TO THE STOCKHOLDERS OF
SONUS NETWORKS, INC., GENBAND HOLDINGS COMPANY, GENBAND INC. AND GENBAND II, INC.
MERGER PROPOSAL—YOUR VOTE IS VERY IMPORTANT

[ ], 2017

Dear Stockholders:

Sonus Networks, Inc. (which we refer to as Sonus), GENBAND Holdings Company (which we refer to as GENBAND), GENBAND Inc. (which we refer to as GB) and GENBAND II, Inc. (which we refer to as GB II) have entered into an agreement and plan of merger (which, as amended or supplemented from time to time, we refer to as the merger agreement) providing for the strategic business combination of Sonus, GENBAND, GB and GB II under a new holding company named Solstice Sapphire Investments, Inc. (which we refer to as New Solstice). As a result of the business combination, New Solstice will succeed to and continue to operate, directly or indirectly, the then existing businesses of Sonus, GENBAND, GB and GB II. The post-closing name of New Solstice will be determined in due course prior to the closing of the mergers.

Former Sonus stockholders will hold approximately 50%, and former GENBAND shareholders, GB stockholders and GB II stockholders, collectively, will hold approximately 50%, of the shares of New Solstice's common stock issued and outstanding immediately after the closing of the transactions contemplated by the merger agreement. New Solstice will apply to list its common stock on the NASDAQ Global Select Market (which we refer to as NASDAQ) under the symbol "[ ]," subject to official notice of issuance. New Solstice does not intend to avail itself of any of the exemptions from certain NASDAQ corporate governance requirements that are available to "controlled companies."

In connection with the transactions contemplated by the merger agreement, Sonus stockholders will be entitled to receive one share of New Solstice common stock for each share of Sonus common stock outstanding as of immediately prior to the effective time of the mergers. Based on Sonus' closing per share price of $6.91 as of August 7, 2017, the shares of New Solstice common stock to be received by Sonus stockholders in connection with the business combination would have an aggregate value of approximately $350.2 million.

The number of shares of New Solstice common stock that GENBAND shareholders, GB stockholders and GB II stockholders will be entitled to receive for their shares of common stock or ordinary shares of GENBAND, GB and GB II (as applicable) will, in the aggregate, be approximately equal to the number of shares of New Solstice common stock issuable to existing Sonus stockholders pursuant to the merger agreement, allocated among GENBAND shareholders, GB stockholders and GB II stockholders in accordance with the terms of the merger agreement and the GENBAND charter documents. Based on the current equity capitalization of Sonus, it is estimated that GENBAND shareholders, GB stockholders and GB II stockholders, collectively, will be entitled to receive approximately 50.7 million shares of New Solstice common stock. Based on Sonus' closing per share price as of August 7, 2017, the shares of New Solstice common stock to be received by GENBAND shareholders, GB stockholders and GB II stockholders in connection with the business combination would have an aggregate value of approximately $350.2 million. In addition, GENBAND shareholders, other than GB and GB II, will have the right to receive a three-year promissory note issued by New Solstice having an aggregate principal amount of $22.5 million and accruing interest at a rate of 7.5% per year for the first six months after the effective time of the mergers and 10% thereafter.

Completion of the transactions contemplated by the merger agreement requires, among other things, the separate approvals of Sonus stockholders, GENBAND shareholders, GB stockholders and GB II stockholders. To obtain these approvals, Sonus will hold a special meeting of Sonus stockholders on [ ], 2017, GENBAND will hold an extraordinary general meeting of GENBAND shareholders on [ ], 2017 and each of GB and GB II will hold a special meeting of its stockholders on [ ], 2017.

Sonus stockholders will not be entitled to appraisal rights in connection with the Sonus merger. A description of the appraisal rights available to GENBAND shareholders, GB stockholders and GB II stockholders as a statutory matter is included in the section entitled "Appraisal Rights" beginning on page 340 of the enclosed joint proxy statement/prospectus.

THE SONUS BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE SONUS STOCKHOLDERS VOTE "FOR" EACH OF THE PROPOSALS TO BE CONSIDERED AT THE SONUS SPECIAL MEETING.

THE GENBAND BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE GENBAND SHAREHOLDERS VOTE "FOR" EACH OF THE PROPOSALS TO BE CONSIDERED AT THE GENBAND EXTRAORDINARY GENERAL MEETING.

THE GB II BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE GB II STOCKHOLDERS VOTE "FOR" EACH OF THE PROPOSALS TO BE CONSIDERED AT THE GB II SPECIAL MEETING.

This document is a prospectus of New Solstice, as well as a proxy statement for each of Sonus, GENBAND, GB and GB II, and provides you with detailed information about the merger agreement, the special meetings of Sonus, GB and GB II stockholders and the extraordinary general meeting of GENBAND shareholders and other matters contemplated by the merger agreement.

1.
  to consider and vote upon a proposal (which we refer to as the Sonus merger proposal) to adopt the agreement and plan of merger, dated as of May 23, 2017 (which, as amended or supplemented from time to time, we refer to as the merger agreement), among Sonus, Solstice Sapphire Investments, Inc., a Delaware corporation and wholly owned subsidiary of Sonus (which we refer to as New Solstice), Solstice Sapphire, Inc., a Delaware corporation and wholly owned subsidiary of New Solstice (which we refer to as Solstice Merger Sub), Green Sapphire Investments LLC, a Delaware limited liability company and wholly owned subsidiary of New Solstice (which we refer to as Cayman Merger Sub), Green Sapphire LLC, a Delaware limited liability company and wholly owned subsidiary of New Solstice (which we refer to as GB Merger Sub), GENBAND Holdings Company, a Cayman Islands exempted company limited by shares (which we refer to as GENBAND), GENBAND Inc., a Delaware corporation (which we refer to as GB) and GENBAND II, Inc., a Delaware corporation (which we refer to as GB II, and together with GENBAND and GB, the GENBAND parties), and approve the merger (which we refer to as the Sonus merger) of Solstice Merger Sub with and into Sonus, with Sonus surviving the Sonus merger as a wholly owned subsidiary of New Solstice;
2.
  to consider and vote upon five separate proposals (which we refer to as the Sonus governance-related proposals) relating to the amended and restated certificate of incorporation of New Solstice that, in accordance with the merger agreement, will be approved and adopted by Sonus as the sole stockholder of New Solstice prior to the mergers and will continue to be in effect after the completion of the mergers (which we refer to as the New Solstice charter) and the principal stockholders agreement that we will enter into with certain of the existing principal stockholders of the GENBAND parties upon completion of the mergers. More specifically, the Sonus governance-related proposals relate to (i) the amount and classes of authorized stock, (ii) board size and composition, (iii) removal of directors, (iv) granting preemptive rights to certain of the existing principal stockholders of the GENBAND parties and (v) electing not to be governed by the provisions of Section 203 of the Delaware General Corporation Law;

3.
  to consider and vote upon a proposal to permit Sonus to adjourn the special meeting, if necessary, for further solicitation of proxies if there are not sufficient votes at the originally scheduled time of the special meeting to approve the Sonus merger proposal and the Sonus governance-related proposals; and
4.
  to consider and vote upon a proposal (which we refer to as the Sonus executive compensation proposal) to approve, by non-binding, advisory vote, certain compensation arrangements for Sonus' named executive officers in connection with the mergers.

The approval by Sonus stockholders of the Sonus merger proposal and the Sonus governance-related proposals is required to complete the mergers under the terms of the merger agreement. Each of the five Sonus governance-related proposals is cross-conditioned upon the approval by Sonus stockholders of the Sonus merger proposal and each other Sonus governance-related proposal, and completion of the mergers is cross-conditioned on the approval by Sonus stockholders of each of the Sonus governance-related proposals. The approval by Sonus stockholders of the Sonus merger proposal is the only approval of Sonus stockholders required by Delaware law to complete the Sonus merger. The approval of the Sonus governance-related proposals is being sought under Rule 14(a)-4(b) under the Securities Exchange Act of 1934, as amended (which we refer to as the Exchange Act), which requires certain matters to be presented separately to stockholders for approval. The approval of the Sonus executive compensation proposal is being sought in accordance with Rule 14a-21(c) under the Exchange Act.

THE SONUS BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT SONUS STOCKHOLDERS VOTE "FOR" EACH PROPOSAL.

However, to ensure your representation at the Sonus special meeting, please submit your proxy, either by mail, by telephone or through the Internet with voting instructions. The submission of your proxy will not prevent you from voting in person, but it will help to secure a quorum and avoid added solicitation costs. Any holder of Sonus common stock entitled to vote who is present at the Sonus special meeting may vote in person instead of by proxy, thereby revoking any previous proxy. A proxy may also be revoked in writing at any time before the vote is taken at the Sonus special meeting. Sonus stockholders will not be entitled to appraisal rights in connection with the Sonus merger.

We encourage you to read the enclosed joint proxy statement/prospectus carefully, including all its annexes and documents incorporated by reference, including the section entitled "Risk Factors" beginning on page 57 of the enclosed joint proxy statement/prospectus.

None of the actions contemplated by the GENBAND governance-related proposals will proceed if the GENBAND merger proposals or any of the GENBAND governance-related proposals is not approved by GENBAND shareholders. As a result, a vote against any of the GENBAND governance-related proposals effectively will be a vote against adoption of the merger agreement and the transactions contemplated by the merger agreement. Failure to gain shareholder approval for any of the GENBAND governance-related proposals could cause the mergers not to close or to close later than expected, and/or could cause GENBAND to incur substantial costs and expenses. If the mergers are completed, the provisions of the New Solstice charter and New Solstice's amended and restated bylaws, including the terms of the shares of New Solstice common stock, will become applicable to GENBAND shareholders who continue as New Solstice stockholders as a result of the mergers regardless of whether they vote in favor of the GENBAND merger or any of the GENBAND governance-related proposals.

THE GB II BOARD OF DIRECTORS RECOMMENDS THAT GB II STOCKHOLDERS VOTE "FOR" EACH PROPOSAL.

Holders of GB II common stock of record at the close of business on [ ], 2017 are entitled to vote at the GB II special meeting, or any adjournment of the GB II special meeting. At least ten days prior to the special meeting, a complete list of stockholders of record as of [ ], 2017, will be available for inspection by any stockholder for any purpose germane to the special meeting, during ordinary business hours, at the office of the Corporate Secretary of GB II, at 3605 E. Plano Parkway, Plano, Texas 75074.

Your vote is important. All GB II stockholders entitled to notice of, and to vote at, the GB II special meeting are cordially invited to attend the GB II special meeting in person. However, to ensure your representation at the GB II special meeting, please submit your proxy by mail with voting instructions. The submission of your proxy will not prevent you from voting in person, but it will help to secure a quorum and avoid added solicitation costs. Any holder of GB II common stock entitled to vote who is present at the GB II special meeting may vote in person instead of by proxy, thereby revoking any previous proxy. A proxy may also be revoked in writing at any time before the vote is taken at the GB II special meeting.

We encourage you to read the enclosed joint proxy statement/prospectus carefully, including all its annexes and documents incorporated by reference, including the section entitled "Risk Factors" beginning on page 57. If you have any questions or need assistance voting your shares, please call GB II at (972) 461-7555.

EXPLANATORY NOTE

This joint proxy statement/prospectus relates to the agreement and plan of merger, dated as of May 23, 2017 (which, as amended or supplemented from time to time, we refer to as the merger agreement), among Sonus Networks, Inc., a Delaware corporation (which we refer to as Sonus), Solstice Sapphire Investments, Inc., a Delaware corporation and wholly owned subsidiary of Sonus (which we refer to as New Solstice), Solstice Sapphire, Inc., a Delaware corporation and wholly owned subsidiary of New Solstice (which we refer to as Solstice Merger Sub), Green Sapphire Investments LLC, a Delaware limited liability company and wholly owned subsidiary of New Solstice (which we refer to as Cayman Merger Sub), Green Sapphire LLC, a Delaware limited liability company and wholly owned subsidiary of New Solstice (which we refer to as GB Merger Sub), GENBAND Holdings Company, a Cayman Islands exempted company limited by shares (which we refer to as GENBAND), GENBAND Inc., a Delaware corporation (which we refer to as GB), and GENBAND II, Inc., a Delaware corporation (which we refer to as GB II, and together with GENBAND and GB, the GENBAND parties).

Upon the terms and subject to the conditions of the merger agreement (a copy of which is attached to this joint proxy statement/prospectus as Annex A), Sonus, GENBAND, GB and GB II have agreed to effect a strategic combination of their respective businesses under a new holding company, New Solstice (which we refer to as the business combination). Pursuant to the merger agreement:

•
  Solstice Merger Sub will merge with and into Sonus, with Sonus surviving the merger as a wholly owned subsidiary of New Solstice (which we refer to as the Sonus merger);
•
  Cayman Merger Sub will merge with and into GENBAND, with GENBAND surviving the merger as a wholly owned subsidiary of New Solstice (which we refer to as the GENBAND merger);
•
  GB will merge with and into GB Merger Sub, with GB Merger Sub surviving the merger as a wholly owned subsidiary of New Solstice (which we refer to as the GB merger); and
•
  GB II will merge with and into GB Merger Sub, with GB Merger Sub surviving the merger as a wholly owned subsidiary of New Solstice (which we refer to as the GB II merger, and together with the GENBAND merger and the GB merger, the GENBAND mergers, and the GENBAND mergers together with the Sonus merger, the mergers).

In connection with the business combination, among other things, (i) the respective businesses of Sonus, GENBAND, GB and GB II will be held under a new holding company, New Solstice, (ii) existing Sonus stockholders will be entitled to receive one share of common stock, par value $0.0001 per share, of New Solstice (which we refer to as New Solstice common stock), for each share of Sonus common stock held by such holders (which we refer to as the Sonus exchange ratio), and (iii) GENBAND shareholders, GB stockholders and GB II stockholders will be entitled to receive for their shares of common stock or ordinary shares (as applicable) of GENBAND, GB and GB II, in the aggregate, a number of shares of New Solstice common stock that is approximately equal to the number of shares of New Solstice common stock issuable to existing Sonus stockholders pursuant to the merger agreement, allocated among GENBAND shareholders, GB stockholders and GB II stockholders in accordance with the terms of the merger agreement and the GENBAND charter documents, and GENBAND shareholders, other than GB and GB II, will additionally have the right to receive a three-year promissory note issued by New Solstice having an aggregate principal amount of $22.5 million and accruing interest at a rate of 7.5% per year for the first six months after the effective time of the mergers and 10% thereafter (which we refer to as the promissory note).

Based on Sonus' closing per share price of $6.91 as of August 7, 2017, the shares of New Solstice common stock to be received by Sonus stockholders in connection with the business combination would have an aggregate value of approximately $350.2 million. Based on the current equity capitalization of

i

Sonus, it is estimated that GENBAND shareholders, GB stockholders and GB II stockholders, collectively, will be entitled to receive approximately 50.7 million shares of New Solstice common stock. Based on Sonus' closing per share price as of August 7, 2017, the shares of New Solstice common stock to be received by GENBAND shareholders, GB stockholders and GB II stockholders in connection with the business combination would have an aggregate value of approximately $350.2 million.

QUESTIONS AND ANSWERS ABOUT
THE MERGERS, THE SPECIAL MEETINGS AND THE EXTRAORDINARY GENERAL MEETING

The following questions and answers are intended to briefly address some commonly asked questions regarding the mergers and the special meetings and extraordinary general meeting. These questions and answers may not address all questions that may be important to you as a stockholder or shareholder (as applicable) of Sonus, GENBAND, GB or GB II. To better understand these matters, and for a description of the legal terms governing the mergers, you should carefully read this entire joint proxy statement/prospectus, including the annexes, as well as the documents that have been incorporated by reference in this joint proxy statement/prospectus. See the section entitled "Where You Can Find More Information" beginning on page 350 of this joint proxy statement/prospectus.

About the Mergers

Q:
  Why am I receiving this joint proxy statement/prospectus?
A:
  Sonus and the GENBAND parties have entered into the merger agreement providing for the business combination of Sonus and the GENBAND parties under a new holding company named Solstice Sapphire Investments, Inc. (which we refer to as New Solstice). Pursuant to the merger agreement, (i) Solstice Merger Sub will merge with and into Sonus, with Sonus surviving the merger as a wholly owned subsidiary of New Solstice (which we refer to as the Sonus merger); (ii) Cayman Merger Sub will merge with and into GENBAND, with GENBAND surviving the merger as a wholly owned subsidiary of New Solstice (which we refer to as the GENBAND merger); (iii) GB will merge with and into GB Merger Sub, with GB Merger Sub surviving the merger as a wholly owned subsidiary of New Solstice (which we refer to as the GB merger); and (iv) GB II will merge with and into GB Merger Sub, with GB Merger Sub surviving the merger as a wholly owned subsidiary of New Solstice (which we refer to as the GB II merger, and together with the GENBAND merger and the GB merger, the GENBAND mergers, and the GENBAND mergers together with the Sonus merger, the mergers). See the section entitled "The Mergers—Structure of the Mergers" beginning on page 106 of this joint proxy statement/prospectus.

  As a result of the transactions contemplated by the merger agreement, former Sonus stockholders and GENBAND party shareholders will own shares of New Solstice common stock, and New Solstice will apply to list its common stock for trading on NASDAQ under the symbol "[ ]," subject to official notice of issuance. Completion of the transactions contemplated by the merger agreement is conditioned upon, among other things, the approval of Sonus stockholders and the GENBAND party shareholders.

Q:
  What are the specific proposals on which I am being asked to vote?
A:
  Sonus is holding a special meeting of stockholders (which we refer to as the Sonus special meeting) in order for stockholders to consider and vote upon the following matters:
  •
    a proposal (which we refer to as the Sonus merger proposal) to adopt the merger agreement and approve the Sonus merger;
  •
    five separate proposals (which we refer to as the Sonus governance-related proposals) relating to the amended and restated certificate of incorporation of New Solstice that will be in effect after the completion of the mergers under the merger agreement (which we refer to as the New Solstice charter) and the principal stockholders agreement that we will enter into with certain of the existing principal stockholders of the GENBAND parties upon completion of the mergers (which we refer to as the OEP Stockholders);
  •
    a proposal (which we refer to as the Sonus adjournment proposal) to permit Sonus to adjourn the Sonus special meeting, if necessary, for further solicitation of proxies if there are not

1

Table of Contents

sufficient votes at the originally scheduled time of the Sonus special meeting to approve the Sonus merger proposal and the Sonus governance-related proposals; and

•
  a proposal (which we refer to as the Sonus executive compensation proposal) to approve, by non-binding, advisory vote, certain compensation arrangements for Sonus' named executive officers in connection with the mergers.

  New Solstice, as a result of the mergers, will succeed to and continue to operate, directly or indirectly, the then existing businesses of Sonus, GENBAND, GB and GB II.

  The approval by Sonus stockholders of the Sonus merger proposal and the Sonus governance-related proposals (which we refer to together as the Sonus stockholder approval) is required to complete the mergers under the terms of the merger agreement. Each of the five Sonus governance-related proposals is cross-conditioned upon the approval by Sonus stockholders of the Sonus merger proposal and each other Sonus governance-related proposal, and completion of the mergers is cross-conditioned on the approval by Sonus stockholders of each of the Sonus governance-related proposals. The approval by Sonus stockholders of the Sonus merger proposal is the only approval of Sonus stockholders required by Delaware law to complete the Sonus merger. The approval of the Sonus governance-related proposals is being sought under Rule 14(a)-4(b) under the Securities Exchange Act of 1934, as amended (which we refer to as the Exchange Act), which requires certain matters to be presented separately to stockholders for approval. The approval of the Sonus executive compensation proposal is being sought in accordance with Rule 14a-21(c) under the Exchange Act.

  GENBAND is holding an extraordinary general meeting of shareholders (which we refer to as the Extraordinary General Meeting) in order to obtain the shareholder approval necessary to, among other things, adopt the merger agreement and the plan of merger related thereto and approve the GENBAND merger (which we refer to as the GENBAND shareholder approval). New Solstice, as a result of the mergers, will succeed to and continue to operate, directly or indirectly, the then existing businesses of Sonus, GENBAND, GB and GB II. GENBAND shareholders will also be asked to approve the adjournment of the Extraordinary General Meeting (if it is necessary to solicit additional proxies if there are not sufficient votes to adopt the merger agreement and the plan of merger related thereto and approve the GENBAND merger).

  GB is holding a special meeting of stockholders (which we refer to as the GB special meeting) in order to obtain the stockholder approval necessary to adopt the merger agreement and approve the GB merger (which we refer to as the GB stockholder approval). GB stockholders will also be asked to approve the adjournment of the GB special meeting (if it is necessary to solicit additional proxies if there are not sufficient votes to adopt the merger agreement and approve the GB merger).

  GB II is holding a special meeting of stockholders (which we refer to as the GB II special meeting) in order to obtain the stockholder approval necessary to adopt the merger agreement and approve the GB II merger (which we refer to as the GB stockholder approval). GB II stockholders will also be asked to approve the adjournment of the GB II special meeting (if it is necessary to solicit additional proxies if there are not sufficient votes to adopt the merger agreement and approve the GB II merger).

  We will be unable to complete the mergers unless the Sonus and GENBAND party stockholder and shareholder approvals (as applicable) are obtained.

  We have included in this joint proxy statement/prospectus important information about the mergers, the merger agreement (a copy of which is included as Annex A to this joint proxy statement/prospectus) , the Sonus special meeting, the Extraordinary General Meeting, the GB special meeting and the GB II special meeting. You should read this information carefully and in

its entirety. The enclosed voting materials allow you to submit your proxy to ensure that your shares are voted at the applicable meeting without attending the Sonus special meeting, the Extraordinary General Meeting, the GB special meeting or the GB II special meeting (as applicable). Your vote is very important and we encourage you to submit your proxy as soon as possible.

Q:
  Should I send my share certificates in with my proxy card?
A:
  No. After the consummation of the mergers, Sonus stockholders, GENBAND shareholders, GB stockholders and GB II stockholders will receive written instructions from the exchange agent on how to exchange their Sonus common stock, GENBAND ordinary shares (which we refer to as GENBAND shares), GB common stock or GB II common stock (as applicable) for shares of New Solstice common stock. Please do not send your Sonus or GENBAND party stock or share certificates (as applicable) with your proxy.

  What will happen to Sonus stock options and other Sonus stock-based awards if the mergers are completed?
A:
  Sonus stock options will generally be treated as follows: (i) each Sonus stock option that is outstanding as of the date that is five business days prior to the closing date of the Sonus merger will become vested in full as of that date (to the extent not previously vested), and the holders of such Sonus stock options will be permitted to exercise such awards on or prior to the date that is three business days prior to the closing date of the Sonus merger; (ii) to the extent not exercised as of the end of day that is three business days prior to the closing date, each Sonus stock option granted under the Sonus Assumed Performance Technologies, Incorporated 2003 Omnibus Incentive Plan, the Sonus Assumed 2008 Network Equipment Technologies Stock Incentive Plan and the Sonus 2012 Amended Performance Technologies Incorporated Omnibus Incentive Plan (which we refer to collectively as the Specified Sonus Plans) will, as of the effective time of the mergers, be assumed by New Solstice and converted into an option to purchase (a) that number of shares of New Solstice common stock (rounded down to the nearest whole share) equal to the product obtained by multiplying (y) the number of shares of Sonus common stock subject to such option immediately prior to the effective time of the mergers by (z) the Sonus exchange ratio, (b) at an exercise price per share equal to the quotient (rounded up to the nearest whole cent) obtained by dividing (y) the exercise price per share of such option immediately prior to the effective time of the mergers by (z) the Sonus exchange ratio and will otherwise continue to have, and be subject to, the same terms and conditions (including vesting arrangements and other terms and conditions set forth in the applicable plan and option agreement) as in effect immediately prior to the effective time of the mergers; and (iii) effective as of the end of the day that is three business days prior to the closing date of the Sonus merger, all Sonus stock options other than Sonus stock options granted under the Specified Sonus Plans will be cancelled to the extent not exercised as of such time.

  Sonus restricted stock units (which we refer to as Sonus RSUs) that are vested by their terms as of immediately prior to the effective time of the mergers (after taking into account any accelerated vesting of the Sonus RSU that occurs by reason of the mergers) will have been settled in shares of Sonus common stock, and each Sonus RSU that is not then vested by its terms (after taking into account any accelerated vesting of the Sonus RSU that occurs by reason of the mergers) and settled in shares of Sonus common stock will, as of the effective time of the mergers, be assumed by New Solstice and converted into a new award of restricted stock units of New Solstice covering a number of shares of New Solstice common stock equal to the product (rounded down to the nearest whole share) of the total number of shares of Sonus common stock then underlying such Sonus RSU multiplied by the Sonus exchange ratio and will otherwise continue to have, and be

Table of Contents

subject to, the same terms and conditions (including the vesting arrangements (and accelerated vesting arrangements) and other terms and conditions set forth in any applicable plan and award agreement) as in effect immediately prior to the effective time of the mergers.

Each share of Sonus common stock issued pursuant to an equity compensation plan of Sonus or any of its subsidiaries that is subject to forfeiture or repurchase restrictions (each of which we refer to as a Sonus Restricted Share) that is not vested by its terms (after taking into account any accelerated vesting of the Sonus Restricted Share that occurs by reason of the mergers) will, at the effective time of the mergers, be converted into New Solstice common stock and will otherwise continue to have, and be subject to, the same terms and conditions (including the forfeiture and repurchase restrictions set forth in any applicable plan and award agreement) as in effect immediately prior to the effective time of the mergers.

With respect to Sonus' Amended and Restated 2000 Employee Stock Purchase Plan, as amended (which we refer to as the Sonus ESPP), if the effective time of the mergers occurs on or before the "Purchase Date" relating to the applicable "Offering Period" in effect on the date of the merger agreement (as such terms are defined in the Sonus ESPP) and there are options granted under the Sonus ESPP (which we refer to as ESPP options) then outstanding with respect to such Offering Period, the Sonus board of directors will provide a "New Purchase Date" (as defined in the Sonus ESPP) for such Offering Period, and any ESPP options will automatically be exercised on the New Purchase Date pursuant to the terms of the Sonus ESPP. If the effective time occurs after the exercise date relating to the applicable Offering Period in effect on the date of the merger agreement, the board of directors of Sonus will timely suspend the Sonus ESPP as of immediately following the exercise date relating to such Offering Period. All shares of Sonus common stock due upon exercise of ESPP options will be issued prior to the effective time of the mergers and no ESPP options will be outstanding as of the effective time of the mergers.

Q:
  What will happen to GENBAND party equity awards if the mergers are completed?
A:
  All outstanding GENBAND shares, including the GENBAND Class B Shares and GENBAND Class E Shares, will be converted into shares of New Solstice common stock and a portion of the promissory note as further described in "Other Related Agreements—The Promissory Note" beginning on page 217 of this joint proxy statement/prospectus. The number of shares of New Solstice common stock and the portion of the promissory note received in respect of each GENBAND Class B Share and GENBAND Class E Share will be determined based on the value of the merger consideration. See the section entitled "The Mergers—Consideration to be Received in Connection with the Transactions Contemplated by the Merger Agreement—GENBAND Party Mergers" on page 108 of this joint proxy statement/prospectus for more information.

  In addition to any shares of New Solstice common stock received in respect of GENBAND Class B Shares and GENBAND Class E Shares, certain employees and directors who hold GENBAND Class E Shares are also eligible to receive additional payments upon consummation of the mergers, in the form of shares of New Solstice common stock. The number of shares of New Solstice common stock to be received by each applicable employee and director will equal the number necessary so that, immediately following the mergers, such employee or director has received an aggregate number of shares of New Solstice common stock, either directly in respect of his or her GENBAND Class E Shares or through this additional payment, equal to the number that would have been received in respect of such employee's or director's GENBAND Class E Shares if the fair value of GENBAND equaled approximately $600 million as of the consummation of the mergers. If the actual fair value of GENBAND equals or exceeds approximately $600 million as of the consummation of the mergers, no additional payment (as described in this paragraph) will be paid to any executive officers or directors. All outstanding GENBAND phantom Class B Shares and GENBAND phantom Class E Shares shall be terminated in exchange

Table of Contents

for a cash payment. Such payment with respect to each GENBAND phantom Class B Share and GENBAND phantom Class E Share shall be equal to the amount of the distributions (as described above), if any, that would be received by a holder with respect to a GENBAND Class B Share or GENBAND Class E Share that is comparable to such GENBAND phantom Class B Share or GENBAND phantom Class E Share. If the comparable GENBAND Class B Share or GENBAND Class E Share does not receive any consideration in the GENBAND merger, the GENBAND phantom Class B Share or GENBAND phantom Class E Share, as applicable, will be terminated for no consideration.

All options to purchase shares in GB (which we refer to as the GB Options) that are outstanding as of the consummation of the GB merger will terminate and cease to be outstanding immediately following the GB merger pursuant to the GB Amended and Restated 1999 Stock Option/Stock Issuance Plan.

Q:
  What conditions must be satisfied to complete the mergers?
A:
  Sonus and the GENBAND parties are not required to complete the mergers unless a number of conditions are satisfied or waived. These conditions include, among others: (i) receipt of the Sonus stockholder approval, GENBAND shareholder approval, GB stockholder approval and GB II stockholder approval; (ii) the authorization for listing by NASDAQ of the New Solstice common stock to be issued as consideration in the mergers; (iii) the expiration or termination of the HSR waiting period; (iv) the absence of any law or order from any court or governmental entity prohibiting or making unlawful the consummation of the transactions contemplated by the merger agreement; (v) the effectiveness of the registration statement on Form S-4 of which this joint proxy statement/prospectus forms a part; and (vi) the receipt by Sonus and GENBAND of certain tax opinions.

  For a more complete summary of the conditions that must be satisfied or waived prior to the completion of the mergers and the other transactions contemplated by the merger agreement, see the section entitled "The Merger Agreement—Conditions to the Mergers" beginning on page 207 of this joint proxy statement/prospectus.

Q:
  What happens if the mergers are not consummated?
A:
  If any of the Sonus stockholder approval, the GENBAND shareholder approval, the GB stockholder approval and the GB II stockholder approval is not obtained, the mergers would not be consummated and the Sonus and GENBAND party shareholders will not receive the merger consideration. Instead, Sonus, GENBAND, GB and GB II would remain independent companies, Sonus common stock would continue to be listed and traded on NASDAQ and Sonus stockholders, GENBAND shareholders, GB stockholders and GB II stockholders would continue to be subject to the same risks and opportunities to which they are currently subject with respect to their ownership of Sonus common stock, GENBAND shares and GB or GB II common stock (as applicable). Under specified circumstances, Sonus may be required to pay a termination fee of $14.5 million to GENBAND if the merger agreement is terminated. See the section entitled "The Merger Agreement—Termination Fee" beginning on page 211 of this joint proxy statement/prospectus.
Q:
  What vote is required to approve each Sonus proposal?
A:
  Sonus Merger Proposal. Approval of the Sonus merger proposal requires the affirmative vote of holders of a majority of the shares of Sonus common stock outstanding and entitled to vote. Accordingly, a Sonus stockholder's failure to submit a proxy card or to vote in person at the Sonus special meeting, an abstention from voting, or the failure of a Sonus stockholder who holds

his or her shares in "street name" through a broker, bank or other nominee to give voting instructions to such broker, bank or other nominee, will have the same effect as voting "AGAINST" the Sonus merger proposal.

Sonus Governance-Related Proposals. Approval of each of the Sonus governance-related proposals requires the affirmative vote of holders of a majority of shares of Sonus common stock present in person or represented by proxy and entitled to vote at the Sonus special meeting on such Sonus governance-related proposal. Accordingly, abstentions with respect to any Sonus governance-related proposal will have the same effect as voting "AGAINST" such Sonus governance-related proposal, while shares not in attendance at the Sonus special meeting and broker non-votes (if any) will have no effect on the outcome of the vote on any Sonus governance-related proposal.

Sonus Adjournment Proposal. Approval of the Sonus adjournment proposal (if necessary to solicit additional proxies if there are not sufficient votes to approve the Sonus merger proposal and the Sonus governance-related proposals) requires the affirmative vote of holders of a majority of shares of Sonus common stock present in person or represented by proxy and entitled to vote at the Sonus special meeting on the Sonus adjournment proposal. Accordingly, abstentions will have the same effect as voting "AGAINST" the Sonus adjournment proposal, while shares not in attendance at the Sonus special meeting and broker non-votes (if any) will have no effect on the outcome of any vote on the Sonus adjournment proposal.

Sonus Executive Compensation Proposal. In accordance with Rule 14a-21(c) under the Exchange Act, Sonus is providing its stockholders with the opportunity to approve the Sonus executive compensation proposal. Approval of the Sonus executive compensation proposal requires the affirmative vote of holders of a majority of shares of Sonus common stock present in person or represented by proxy and entitled to vote at the Sonus special meeting on the Sonus executive compensation proposal. Accordingly, abstentions will have the same effect as voting "AGAINST" the Sonus executive compensation proposal, while shares not in attendance at the Sonus special meeting and broker non-votes (if any) will have no effect on the outcome of the vote on the Sonus executive compensation proposal.

Q:
  What are the recommendations of the Sonus board of directors?
A:

Q:
  When do you expect the mergers and the other transactions contemplated by the merger agreement to be completed?
A:
  Sonus and the GENBAND parties are working to complete the mergers and the other transactions contemplated by the merger agreement as soon as possible, and we anticipate that they will occur in October 2017. However, the mergers and the other transactions contemplated by the merger agreement are subject to regulatory approval and other conditions which are described in more detail in this joint proxy statement/prospectus, and it is possible that factors outside the control of Sonus and the GENBAND parties could result in the mergers being completed at a later time, or not at all.
Q:
  Are Sonus stockholders entitled to appraisal rights?
A:
  No. Under the Delaware General Corporation Law (which we refer to as the DGCL), Sonus stockholders do not have appraisal rights in connection with the Sonus merger.
Q:
  Are GENBAND shareholders entitled to appraisal rights?
A:
  With respect to the GENBAND merger, the Companies Law (2016 Revision) provides for a right of dissenting stockholders, in certain situations, to be paid the fair value of their shares upon their dissenting to the merger if they follow a prescribed procedure as further discussed in the section entitled "Appraisal Rights" beginning on page 340 of this joint proxy statement/prospectus. Notwithstanding the foregoing, in accordance with the Fifth Amended and Restated Stockholders Agreement, dated as of July 30, 2013 and as amended, by and among GENBAND, GB, GB II and AN Holdings, Inc., and other certain holders of GENBAND, GB, GB II and AN Holdings, Inc. shares (which we refer to as the GENBAND Stockholders Agreement), certain affiliates of One Equity Partners, a majority shareholder of GENBAND (which we refer to as OEP), have the right to cause stockholders or shareholders (as applicable) of the GENBAND parties holding a majority of shares to vote in favor of the approval of the GENBAND mergers. If OEP exercises this right, then a majority of the shareholders or stockholders (as applicable) of the GENBAND parties would be required to waive their dissenter's rights, appraisal rights or similar rights in connection with the GENBAND mergers. See the section entitled "Appraisal Rights" beginning on page 340 of this joint proxy statement/prospectus for further discussion of appraisal rights of GENBAND shareholders.
Q:
  Are GB stockholders and GB II stockholders entitled to appraisal rights?
A:
  As a statutory matter appraisal rights are available with respect to the GB merger and the GB II merger under Section 262 of the DGCL. However, under the terms of the GENBAND Stockholders Agreement, OEP has the right to require GB and GB II stockholders holding a majority of common stock of GB and GB II, respectively, to vote in favor of the GB merger or the GB II merger, respectively. To the extent a GB stockholder or GB II stockholder does not vote in favor of (or return a separate proxy voting in favor of) the adoption of the merger agreement and the approval of the GB merger or GB II merger, as applicable, OEP may exercise the proxy granted to it by the GENBAND Stockholders Agreement to vote any such stockholder's shares in favor of the adoption of the merger agreement and the approval of the GB merger or GB II merger, as applicable. Under Section 262 of the DGCL, only stockholders who do not vote in favor of a merger are entitled to exercise appraisal rights in connection therewith. Accordingly, any stockholder whose shares are voted in favor of the GB merger or the GB II merger, including

10

Table of Contents

pursuant to the provisions of the GENBAND Stockholders Agreement, will not be entitled to exercise appraisal rights in connection with such mergers. See the section entitled "Appraisal Rights" beginning on page 340 of this joint proxy statement/prospectus for further discussion of appraisal rights of GB stockholders and GB II stockholders.

Q:
  If the mergers are completed, when can Sonus stockholders, GENBAND shareholders, GB stockholders and GB II stockholders expect to receive the merger consideration?
A:
  At the effective time of the Sonus merger, any shares of Sonus common stock held by you will automatically convert into the right to receive the number of shares of New Solstice common stock approximately equal to the number of shares of Sonus common stock that you owned immediately prior to the completion of the Sonus merger.

  At the effective time of the GENBAND merger, any GENBAND shares held by you will, subject to the terms of the merger agreement and the GENBAND charter documents, automatically convert into the right to receive a portion of a share of New Solstice common stock and such share's portion of the promissory note issued by New Solstice to shareholders of GENBAND that the holder of such GENBAND share is entitled to receive as further described in the section entitled "The Mergers—Consideration to be Received in Connection with the Transactions Contemplated by the Merger Agreement" beginning on page 107 of this joint proxy statement/prospectus.

  At the effective time of the GB merger, any shares of GB common stock held by you will, subject to the terms of the merger agreement and the GENBAND charter documents, automatically convert into the right to receive the number of shares of New Solstice common stock approximately equal to the number of shares of GB common stock that you owned immediately prior to the completion of the GB merger multiplied by the exchange ratio described in the section entitled "The Mergers—Consideration to be Received in Connection with the Transactions Contemplated by the Merger Agreement" beginning on page 107 of this joint proxy statement/prospectus.

  At the effective time of the GB II merger, any shares of GB II common stock held by you will, subject to the terms of the merger agreement and the GENBAND charter documents, automatically convert into the right to receive the number of shares of New Solstice common stock approximately equal to the number of shares of GB II common stock that you owned immediately prior to the completion of the GB II merger multiplied by the exchange ratio described in the section entitled "The Mergers—Consideration to be Received in Connection with the Transactions Contemplated by the Merger Agreement" beginning on page 107 of this joint proxy statement/prospectus.

  After the mergers are completed, New Solstice will cause the exchange agent to mail to (i) each holder of record of one or more certificates representing shares of Sonus common stock, GB common stock or GB II common stock one or more letters of transmittal and instructions for effecting the surrender of the certificates in exchange for New Solstice certificates and cash in lieu of fractional shares, if any, and upon surrender of a certificate for cancellation, the holder of such certificate will be entitled to receive in exchange therefor a New Solstice certificate representing that number of shares of New Solstice common stock to which the holder thereof is entitled, together with a check for the cash to be paid in lieu of fractional shares, if any; (ii) each holder of record of shares of Sonus common stock represented (immediately prior to the effective time of the Sonus merger) by book-entry on the records of Sonus or Sonus' transfer agent, on behalf of New Solstice, notice that such holder has become the holder of record of the same number of shares of New Solstice common stock, together with a check for the cash to be paid in lieu of fractional shares, if any; and (iii) each holder of record of GENBAND shares one or more letters

11

Table of Contents

of transmittal which shall be in customary form for a Cayman Islands-incorporated company and instructions for effecting the surrender of the certificates, if any, in exchange for New Solstice certificates and cash in lieu of fractional shares, if any, and in the case of GENBAND shares not represented by a certificate or certificates such other documents as may be required in exchange for the applicable New Solstice certificates, if any, and upon either the surrender of a GENBAND certificate for cancellation to the exchange agent, or with respect to uncertificated GENBAND shares, confirmation by GENBAND that the uncertificated GENBAND shares have been cancelled, in each case together with a letter of transmittal, duly executed and completed in accordance with the instructions thereto, the holder of such GENBAND shares will be entitled to receive in exchange therefor a New Solstice certificate representing that number of shares of New Solstice common stock to which the holder thereof is entitled, together with a check for the cash to be paid in lieu of fractional shares, if any.

Q:
  As a GENBAND shareholder, GB stockholder or GB II stockholder, will I receive any distribution from the merger consideration?
A:
  As further described in the section entitled "The Mergers—Consideration to be Received in Connection with the Transactions Contemplated by the Merger Agreement—GENBAND Party Mergers" beginning on page 108 of this joint proxy statement/prospectus, the distribution of merger consideration to the holders of GENBAND shares, GB common stock and GB II common stock is subject to the liquidation waterfall as set forth in Article 5.2 of the GENBAND Articles of Association attached as Annex C to this joint proxy statement/prospectus. The consideration amount distributed to the shareholders of the GENBAND parties is to be calculated according to this waterfall and, depending on the final total consideration on the closing date of the mergers, the merger consideration distributed to certain shareholders may be zero. Under the merger agreement, GENBAND shareholders, other than GB and GB II, will also have the right to receive a three-year promissory note issued by New Solstice as described in the section entitled "Other Related Agreements—The Promissory Note" beginning on page 217 of this joint proxy statement/prospectus. Consideration from the promissory note will be distributed to GENBAND shareholders, other than GB and GB II, in accordance with the waterfall. Pursuant to the terms of the merger agreement, GB and GB II stockholders are not entitled to receive any consideration under the promissory note.
Q:
  What happens if I sell my shares of Sonus common stock, GB common stock or GB II common stock or my GENBAND shares after the applicable special meeting or extraordinary general meeting, but before the effective time of the mergers?
A:
  If you transfer your shares of Sonus common stock, GB common stock or GB II common stock or your GENBAND shares after the Sonus, GENBAND, GB or GB II special meeting or extraordinary general meeting, respectively, but before the effective time of the mergers, you will have transferred the right to receive the applicable merger consideration. In order to receive the applicable merger consideration, you must hold your shares of Sonus common stock, GB common stock or GB II common stock or your GENBAND shares through the completion of the mergers and the other transactions contemplated by the merger agreement.
Q:
  What if I hold shares in both Sonus and one or more of the GENBAND parties, or in more than one of the GENBAND parties?
A:
  If you are a stockholder in both Sonus and one or more of the GENBAND parties, or in more than one of the GENBAND parties, you will receive two or more separate packages of voting materials. A vote cast as a Sonus stockholder for any Sonus proposal will not constitute a vote cast as a GENBAND shareholder for the proposal to adopt the merger agreement and approve the

12

Table of Contents

GENBAND merger, or vice versa. Similarly, a vote cast as a GENBAND shareholder for the proposal to adopt the merger agreement and approve the GENBAND merger will not constitute a vote cast as a GB or GB II stockholder for the proposal to adopt the merger agreement and approve the GB or GB II merger, or vice versa. Therefore, please mark, sign, date and return the proxy cards you receive from Sonus, GENBAND, GB and/or GB II, or submit proxies as a Sonus stockholder over the Internet or by telephone.

  The Sonus board is providing these Sonus proxy materials to you. These materials also constitute a prospectus with respect to the New Solstice common stock issuable to Sonus stockholders, GENBAND shareholders, GB stockholders and GB II stockholders in connection with the mergers.
Q:
  When and where will the Sonus special meeting be held?
A:
  The Sonus special meeting will be held at the offices of Wilmer Cutler Pickering Hale and Dorr LLP, located at 60 State Street, Boston, Massachusetts 02109 on [ ], 2017, at [ ], Eastern time, unless the special meeting is adjourned.
Q:
  Who is entitled to vote at the Sonus special meeting?
A:
  Sonus has fixed [ ], 2017 as the record date for the Sonus special meeting (which we refer to as the Sonus record date). If you were a Sonus stockholder at the close of business on the Sonus record date, you are entitled to vote on matters that come before the Sonus special meeting or any adjournments thereof. However, a Sonus stockholder may only vote his, her or its shares if such holder is present in person or is represented by proxy at the Sonus special meeting.
Q:
  How many votes do I have?
A:
  Sonus stockholders are entitled to one vote at the Sonus special meeting for each share of Sonus common stock held of record as of the Sonus record date. As of the close of business on the Sonus record date, there were [ ] shares of Sonus common stock outstanding and entitled to vote at the Sonus special meeting.

  At the close of business on the Sonus record date, the directors and executive officers of Sonus and certain of their affiliates were entitled to vote approximately [ ] shares of Sonus common stock, or [ ]% of the shares of Sonus common stock outstanding on that date. Approval of the Sonus merger proposal requires the affirmative vote of the holders of a majority of the total issued and outstanding shares of Sonus common stock on the record date. We currently expect that Sonus' directors and executive officers will vote their shares in favor of each of the proposals to be considered at the Sonus special meeting, although none of them has entered into any agreement obligating them to do so.

Q:
  My shares are held in "street name" by my broker. Will my broker automatically vote my shares for me?
A:
  No. If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the "beneficial holder" of the shares held for you in what is known as "street name." If this is the case, this joint proxy statement/prospectus has been forwarded to you by your broker, bank or other nominee, or its agent. As the beneficial holder, you have the right to direct your broker, bank, nominee or other holder of record as to how to vote your shares. If you do not

Table of Contents

provide voting instructions to your broker, bank or other nominee on a particular proposal on which your broker, bank or other nominee does not have discretionary authority to vote, your shares will not be voted on that proposal. This is called a "broker non-vote." Because brokers, banks and other nominees do not have discretionary voting authority with respect to any of the proposals described in this joint proxy statement/prospectus, if you, as a beneficial owner of shares of Sonus common stock held in "street name," do not give voting instructions to the broker, bank, nominee or other holder of record, then those shares will not be voted on any of the proposals described in this joint proxy statement/prospectus and will have the same effect as voting "AGAINST" the Sonus merger proposal, and will have no effect on the outcome of any vote on any of the Sonus governance-related proposals, the Sonus adjournment proposal and the Sonus executive compensation proposal. If you hold shares of Sonus common stock through a broker, bank, nominee or other holder of record with custody of your shares, follow the voting instructions you receive from that organization.

Q:
  What do I need to do now?
A:
  You should read and consider the information contained in this joint proxy statement/prospectus, including the annexes, as well as the documents that have been incorporated by reference into this joint proxy statement/prospectus, carefully and then please submit your proxy as soon as possible so that your shares may be represented and voted at the Sonus special meeting.
Q:
  How do Sonus stockholders vote?
A:
  You can vote in person by completing a ballot at the Sonus special meeting, or you can submit your proxy to have your shares of Sonus common stock voted by proxy at the Sonus special meeting. Even if you plan to attend the Sonus special meeting, we encourage you to submit your proxy as soon as possible. After carefully reading and considering the information contained in this joint proxy statement/prospectus, including the annexes, as well as the documents that have been incorporated by reference into this joint proxy statement/prospectus, please submit your proxy by telephone or over the Internet in accordance with the instructions set forth on the enclosed proxy card, or mark, sign and date the proxy card, and return it in the enclosed postage-paid envelope as soon as possible so that your shares may be voted at the Sonus special meeting. For detailed information, see the section entitled "The Sonus Special Meeting—How to Submit Your Proxy" beginning on page 84 of this joint proxy statement/prospectus. YOUR VOTE IS VERY IMPORTANT.
Q:
  Can I change my vote after I have submitted a proxy by telephone or over the Internet or submitted my completed proxy card?
A:
  Yes. You may revoke your proxy and change your vote at any time before the polls close at the Sonus special meeting. You may do this by signing and submitting a new proxy card (or revocation) with a later date, submitting a proxy by telephone or submitting a proxy over the Internet (your latest telephone or Internet proxy is counted) or by attending the Sonus special meeting and voting in person. Attending the Sonus special meeting by itself, however, will not revoke your proxy unless you specifically request it.

  If you have instructed your broker, bank or other nominee to vote your shares, you must follow directions received from your broker, bank or other nominee to change your vote.

The Mergers and the Merger Agreement (Page 106)

Sonus and GENBAND have entered into the merger agreement which, among other things, contemplates four separate mergers: the Sonus merger, the GENBAND merger, the GB merger and the GB II merger, each of which is discussed below. The mergers will result in Sonus' and GENBAND's businesses being held under New Solstice. Former Sonus stockholders will own approximately 50%, and former GENBAND party shareholders will own approximately 50%, of the shares of New Solstice common stock issued and outstanding immediately following the consummation of the mergers. The post-closing name of New Solstice will be determined in due course prior to the closing of the mergers.

Consideration to be Received in Connection with the Transactions Contemplated by the Merger Agreement (Page 107)

At the effective time of the Sonus merger, each share of Sonus common stock issued and outstanding immediately prior to the effective time of the Sonus merger (other than Sonus common stock owned by Sonus immediately prior to the effective time of the Sonus merger) will be converted into and become the right to receive one share of New Solstice common stock.

At the effective time of the GENBAND merger, each GENBAND share issued and outstanding immediately prior to the effective time of the GENBAND merger (other than shares of capital stock or other equity interests of GENBAND owned by GENBAND, GB or GB II immediately prior to the effective time of the GENBAND merger) will be converted into and become the right to receive a portion of a share of New Solstice common stock and such share's portion of the promissory note issued by New Solstice to shareholders of GENBAND that the holder of such GENBAND share is entitled to receive as further described in the section entitled "The Mergers—Consideration to be Received in Connection with the Transactions Contemplated by the Merger Agreement" beginning on page 107 of this joint proxy statement/prospectus. The promissory note does not amortize and the principal thereon is payable in full on the third anniversary of its execution. Interest on the promissory note is payable quarterly in arrears and accrues at a rate of 7.5% per annum for the first six months after issuance, and thereafter at a rate of 10% per annum. The failure to make any payment under the promissory note when due and, with respect to payment of any interest, the continuation of such failure for a period of thirty days thereafter, constitutes an event of default under the promissory note. If an event of default occurs under the promissory note, the payees may declare the entire balance of the promissory note due and payable (including principal and accrued and unpaid interest) within five business days of the payees' notification to New Solstice of such acceleration. For additional information regarding the terms of the promissory note, see "Other Related Agreements—The Promissory Note" beginning on page 217 of this joint proxy statement/prospectus.

At the effective time of the GB merger and the GB II merger, respectively, each share of GB and GB II common stock issued and outstanding immediately prior to the effective time of the GB merger and GB II merger, respectively (other than GB common stock owned by GB or GB II common stock owned by GB II, in each case, immediately prior to the effective time of the GB merger or the GB II merger, respectively, and which we refer to as excluded GB shares), will be converted into and become the right to receive a share of New Solstice common stock multiplied by the exchange ratio described in the section entitled "The Mergers—Consideration to be Received in Connection with the

Interests of Directors and Executive Officers in the Transactions (Page 171)

•
  Continuing employment of certain executive officers of Sonus by the combined company; and
•
  Certain other one-time and retention bonus payments for certain executive officers of Sonus.

In considering the recommendation of the GENBAND, GB and GB II boards that GENBAND shareholders, GB stockholders and GB II stockholders, respectively, adopt the merger agreement and approve the transactions contemplated thereby, GENBAND shareholders, GB stockholders and GB II stockholders should be aware that members of the GENBAND, GB and GB II boards and the executive officers of GENBAND, GB and GB II have interests in the transactions contemplated by the merger agreement that may be different from, or in addition to, or may conflict with, the interests of GENBAND shareholders, GB stockholders and GB II stockholders generally. These interests relate to or arise from, among other things, the following events or circumstances:

•
  The accelerated vesting and/or payment in respect of GENBAND Class E Shares held by certain executive officers and directors of GENBAND, GB and GB II;
•
  The grant of New Solstice equity to certain executive officers and directors of GENBAND, GB and GB II who currently hold GENBAND Class E Shares;

  Certain existing executive officers of GENBAND, GB and GB II, including Daryl E. Raiford, are expected to continue to be employed as New Solstice executive officers following consummation of the mergers. The composition of the New Solstice executive officer team has not yet been finalized;
•
  Certain existing directors of GENBAND, GB and GB II are expected to continue to be engaged as New Solstice directors following consummation of the mergers. The composition of the New Solstice board has not yet been finalized;
•
  The right to continued indemnification for directors and executive officers of GENBAND and GB following the completion of the mergers and the other transactions contemplated by the merger agreement, pursuant to the terms of the merger agreement and indemnification agreements entered into by certain directors and officers of the GENBAND parties, as described in more detail below;
•
  Certain executive officers and directors may enter into agreements with one or more of the GENBAND parties pursuant to which (i) such executive officers and directors waive their rights to certain payments and benefits subject to receipt of shareholder approval of such payments in accordance with Section 280G (which we refer to as Section 280G) of the Internal Revenue Code of 1986, as amended (which we refer to as the Code), and (ii) the GENBAND parties may agree to seek such shareholder approval for purposes of Section 280G. No such agreements have been entered into to date and the GENBAND parties have no obligation to obtain shareholder approval for purposes of Section 280G and receipt of such shareholder approval is not a condition to the consummation of the mergers; and
•
  The affiliation of certain directors and officers of the GENBAND parties with OEP and its affiliates. As further described in the section titled "Related Person Transactions" beginning on page 339 of this joint proxy statement/prospectus, GENBAND is party to a Subordinated Term Loan (as defined in the section entitled "GENBAND Management's Discussion and Analysis of Financial Condition and Results of Operations" beginning on page 218 of this joint proxy statement/prospectus) with an affiliate of OEP, under which all outstanding amounts are expected to be paid off in connection with the mergers. GENBAND is also party to a management fee agreement with OEP, which will be terminated in connection with the closing. All management fees payable to OEP (approximately $10 million) are expected to be paid off prior to the consummation of the mergers. In addition, the merger agreement contemplates, as a condition to the closing of the transactions contemplated thereby, that at the closing, New Solstice will enter into a stockholders agreement with the OEP Stockholders.

In addition, pursuant to indemnification agreements entered into by GENBAND and GB and certain of their respective directors and officers, GENBAND and GB have agreed to (i) indemnify their directors and officers to the fullest extent permitted by applicable law from and against any and all Costs (as defined in the applicable indemnification agreement) and (ii) advance all expenses (including attorney's fees and expenses) incurred by such indemnitee or any other Indemnified Person (as defined in the in the applicable indemnification agreement).

Regulatory Matters Relating to the Transactions (Page 184)

Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (which we refer to as the HSR Act), the transactions contemplated by the merger agreement may not be completed until notification and report forms have been filed with the Antitrust Division of the U.S. Department of Justice (which we refer to as the DOJ) and the U.S. Federal Trade Commission (which we refer to as the FTC) and the applicable waiting period has expired or been terminated. Sonus and GENBAND each filed the required Notification and Report Forms pursuant to the HSR Act with the DOJ and the

40

Table of Contents

FTC on June 7, 2017, and on June 29, 2017, the FTC granted early termination of the applicable waiting period under the HSR Act, effective immediately.

Sonus and GENBAND derive revenues in certain other jurisdictions where merger control filings or clearances may be required or advisable. Under the merger agreement, the parties' obligations to effect the transactions contemplated by the merger agreement are conditioned on the receipt of any approvals required or deemed advisable under relevant antitrust laws. Sonus and GENBAND have agreed to make such filings and/or take such actions as promptly as practicable. An additional condition to the consummation of the transactions contemplated by the merger agreement is the absence of any decree, order, or injunction of any governmental authority of competent jurisdiction which prohibits or makes unlawful the consummation of any of the transactions contemplated by the merger agreement.

Sonus and the GENBAND parties have agreed to use their reasonable best efforts to obtain any government clearances or approvals, or expirations or terminations of waiting periods, required for the consummation of the transactions contemplated by the merger agreement under the HSR Act and any antitrust laws, and to take, or cause to be taken, all actions necessary, proper or advisable under applicable antitrust laws to consummate and make effective the transactions contemplated by the merger agreement as promptly as practicable. The use of such reasonable best efforts requires Sonus and the GENBAND parties to vigorously contest and resist any action or proceeding, including administrative or judicial action or proceeding, that would restrict, prevent or prohibit consummation of the transactions contemplated by the merger agreement, including reasonably pursuing administrative and judicial appeals. However, neither Sonus nor any GENBAND party is required to agree to any material divestitures, licenses, hold separate arrangements or similar matters, including material covenants affecting business operating practices, except to the extent any such divestitures, licenses, arrangements, matters or covenants would not reasonably be expected to be material to Sonus and the GENBAND parties, taken as a whole.

Treatment of Sonus Equity Awards (Page 193)

The merger agreement provides that:

•
  each Sonus stock option outstanding as of the date that is five business days prior to the closing date of the Sonus merger will become vested in full as of that date (to the extent not previously vested), and the holders of such Sonus stock options will be permitted to exercise such awards on or prior to the date that is three business days prior to the closing date of the Sonus merger;
•
  to the extent not exercised as of the end of day that is three business days prior to the closing date, each Sonus stock option granted under the Specified Sonus Plans will not be permitted to be exercised between such time and the effective time of the mergers and will, as of the effective time of the mergers, be assumed by New Solstice and converted into an option to purchase (a) that number of shares of New Solstice common stock (rounded down to the nearest whole share) equal to the product obtained by multiplying (y) the number of shares of Sonus common stock subject to such option immediately prior to the effective time of the mergers by (z) the Sonus exchange ratio, (b) at an exercise price per share equal to the quotient (rounded up to the nearest whole cent) obtained by dividing (y) the exercise price per share of such option immediately prior to the effective time of the mergers by (z) the Sonus exchange ratio and will otherwise continue to have, and be subject to, the same terms and conditions (including vesting arrangements and other terms and conditions set forth in the applicable plan and option agreement) as in effect immediately prior to the effective time of the mergers;
•
  effective as of the end of the day that is three business days prior to the closing date of the Sonus merger, all Sonus stock options other than Sonus stock options granted under the Specified Sonus Plans will be cancelled to the extent not exercised as of such time;

41

Table of Contents

•
  Sonus RSUs that are vested by their terms as of immediately prior to the effective time of the mergers (after taking into account any accelerated vesting of the Sonus RSU that occurs by reason of the mergers) will have been settled in shares of Sonus common stock, and each Sonus RSU that is not then vested by its terms (after taking into account any accelerated vesting of the Sonus RSU that occurs by reason of the mergers) and settled in shares of Sonus common stock will, as of the effective time of the mergers, be assumed by New Solstice and converted into a new award of restricted stock units of New Solstice covering a number of shares of New Solstice common stock equal to the product (rounded down to the nearest whole share) of the total number of shares of Sonus common stock then underlying such Sonus RSU multiplied by the Sonus exchange ratio and will otherwise continue to have, and be subject to, the same terms and conditions (including the vesting arrangements (and accelerated vesting arrangements) and other terms and conditions set forth in any applicable plan and award agreement) as in effect immediately prior to the effective time of the mergers; and
•
  each Sonus Restricted Share that is not vested by its terms (after taking into account any accelerated vesting of the Sonus Restricted Share that occurs by reason of the mergers) will, at the effective time of the mergers, be converted into New Solstice common stock and will otherwise continue to have, and be subject to, the same terms and conditions (including the forfeiture and repurchase restrictions set forth in any applicable plan and award agreement) as in effect immediately prior to the effective time of the mergers.

In addition, with respect to the Sonus ESPP, if the effective time of the mergers occurs on or before the "Purchase Date" relating to the applicable "Offering Period" in effect on the date of the merger agreement (as such terms are defined in the Sonus ESPP) and there are ESPP options then outstanding with respect to such Offering Period, the Sonus board of directors will provide a "New Purchase Date" (as defined in the Sonus ESPP) for such Offering Period, and any ESPP options will automatically be exercised on the New Purchase Date pursuant to the terms of the Sonus ESPP. If the effective time occurs after the exercise date relating to the applicable Offering Period in effect on the date of the merger agreement, the board of directors of Sonus will timely suspend the Sonus ESPP as of immediately following the exercise date relating to such Offering Period. All shares of Sonus common stock due upon exercise of ESPP options will be issued prior to the effective time of the mergers and no ESPP options will be outstanding as of the effective time of the mergers.

Listing of New Solstice Common Stock on NASDAQ; Delisting and Deregistering of Sonus Common Stock (Page 188)

It is a condition to the completion of the mergers that the New Solstice common stock to be issued in connection with the transactions contemplated by the merger agreement be authorized for listing on NASDAQ, subject to official notice of issuance. If the mergers are completed, Sonus common stock will be delisted from NASDAQ and deregistered under the Exchange Act, and Sonus will no longer be required to file periodic reports with the Securities and Exchange Commission (which we refer to as the SEC) on account of Sonus common stock.

Appraisal Rights (Page 340)

Under the DGCL, Sonus stockholders do not have appraisal rights in connection with the Sonus merger. A description of the appraisal rights available, as a statutory matter, to GENBAND shareholders, GB stockholders and GB II stockholders and procedures required to exercise statutory appraisal rights is included in the section entitled "Appraisal Rights" beginning on page 340 of this joint proxy statement/prospectus.

Table of Contents

No Solicitation (Page 201)

Sonus, New Solstice, Solstice Merger Sub, Cayman Merger Sub and GB Merger Sub (which we refer to collectively as the Sonus parties) have agreed, from the date of the merger agreement until the effective time of the mergers, or, if earlier, the termination of the merger agreement in accordance with its terms, not to maintain, initiate, solicit or knowingly encourage or facilitate any Sonus acquisition proposal (as defined under the heading "The Merger Agreement—No Solicitation—No Solicitation by Sonus" beginning on page 201 of this joint proxy statement/prospectus) or any inquiry or proposal that would reasonably be expected to lead to a Sonus acquisition proposal from any third party, or participate in any discussions or negotiations regarding any acquisition proposal or any inquiry or proposal that would reasonably be expected to lead to a Sonus acquisition proposal. Notwithstanding these restrictions, the merger agreement provides that, subject to certain conditions, prior to obtaining the Sonus stockholder approval, under specified circumstances, the Sonus board may furnish information to, or participate in discussions and negotiations with, third parties in response to an unsolicited, bona fide written acquisition proposal if the Sonus board determines in good faith, after consultation with outside counsel, that such acquisition proposal constitutes, or could reasonably be expected to result in, a superior proposal (as defined under the heading "The Merger Agreement—No Solicitation—No Solicitation by Sonus" beginning on page 201 of this joint proxy statement/prospectus).

The GENBAND parties have agreed, from the date of the merger agreement until the effective time of the mergers, or, if earlier, the termination of the merger agreement in accordance with its terms, not to maintain, initiate or solicit or knowingly encourage or facilitate a GENBAND acquisition proposal (as defined under the heading "The Merger Agreement—No Solicitation—No Solicitation by GENBAND Parties" beginning on page 203 of this joint proxy statement/prospectus), or participate in any discussions or negotiations regarding any acquisition proposal or any inquiry or proposal that would reasonably be expected to lead to a GENBAND acquisition proposal.

Conditions to Completion of the Mergers (Page 207)

The completion of the transactions contemplated by the merger agreement is subject to the satisfaction or waiver of certain conditions, including, among others: (i) receipt of the Sonus stockholder approval, GENBAND shareholder approval, GB stockholder approval and GB II stockholder approval; (ii) the authorization for listing by NASDAQ of the New Solstice common stock to be issued as consideration in the mergers; (iii) the expiration or termination of the HSR waiting period; (iv) the absence of any law or order from any court or governmental entity prohibiting or making unlawful the consummation of the transactions contemplated by the merger agreement; (v) the effectiveness of the registration statement on Form S-4 of which this joint proxy statement/prospectus forms a part; and (vi) the receipt by Sonus and GENBAND of certain tax opinions.

Termination of the Merger Agreement (Page 210)

The merger agreement may be terminated at any time prior to the closing (i) by the mutual written consent of Sonus and GENBAND; (ii) by either Sonus or GENBAND if (a) the closing has not occurred by February 23, 2018 or, if extended by either Sonus or GENBAND in accordance with the terms of the merger agreement, May 31, 2018, (b) if a meeting of Sonus' stockholders has been held and the Sonus stockholders have voted upon and have not approved the merger agreement, or (c) if any law makes consummation of any of the transactions illegal or otherwise prohibited, or if any judgment, injunction, order or decree of a competent governmental authority enjoining any of the parties from consummating the transactions shall have been entered and such judgment, injunction, order or decree shall have become final and nonappealable; (iii) by Sonus if (a) whether before or after stockholder approval, there has been a breach by any GENBAND party or any GENBAND member of any representation, warranty, covenant or agreement set forth in the merger agreement or the voting agreement or if any such representation or warranty of any GENBAND party or any

43

Table of Contents

GENBAND member shall have become untrue, in either case such that the conditions of the GENBAND parties with respect to the accuracy of representations and warranties would not be satisfied, and such breach or failure of a representation or warranty to be true is not curable, or, if curable, is not cured within 30 days after written notice of such breach or failure of a representation or warranty to be true is given to GENBAND by Sonus, (b) Sonus has received a superior proposal prior to receipt of all necessary stockholder approvals, provided that Sonus has complied in all material respects with its obligations under the merger agreement with respect to such superior proposal and Sonus pays to GENBAND in immediately available funds the termination fee, or (c) if a meeting of stockholders of any GENBAND party has been held and such stockholders have voted upon and have not approved the merger agreement; and (iv) by GENBAND if (a) whether before or after stockholder approval, there has been a breach by any of the Sonus parties of any representation, warranty, covenant or agreement set forth in the merger agreement or if any such representation or warranty of any Sonus party shall have become untrue, in either case such that the conditions of Sonus with respect to the accuracy of representations and warranties would not be satisfied, and such breach or failure of a representation or warranty to be true is not curable, or, if curable, is not cured within 30 days after written notice of such breach or failure of a representation or warranty to be true is given to Sonus by GENBAND, or (b) prior to the Sonus stockholders meeting (including adjournments or postponement) in the event that (x) the board of directors of Sonus makes a change of recommendation or (y) a Sonus acquisition proposal was publicly announced or disclosed, the Sonus board of directors fails to affirm the Sonus board recommendation within 10 business days after receipt of a GENBAND written request to do so.

Termination Fee Relating to the Mergers (Page 211)

Under specified circumstances, Sonus may be required to pay a termination fee of $14.5 million to GENBAND if the merger agreement is terminated. See section entitled "The Merger Agreement—Termination Fee" beginning on page 211 of this joint proxy statement/prospectus.

Comparison of Stockholder Rights (Page 294)

As a result of the mergers, the holders of Sonus common stock and the holders of GENBAND shares, GB common stock and GB II common stock will become holders of New Solstice common stock. Following the mergers, former Sonus stockholders and former GENBAND party shareholders will have different rights as stockholders of New Solstice than they had as stockholders of Sonus or shareholders or stockholders (as applicable) of the GENBAND parties due to the different provisions of the governing documents of Sonus, the GENBAND parties and New Solstice. For additional information comparing the rights of stockholders of Sonus, the GENBAND parties and New Solstice, see the section entitled "Comparison of Stockholder Rights" beginning on page 294 of this joint proxy statement/prospectus.

Material U.S. Federal Income Tax Consequences of the Sonus Merger to U.S. Holders of Sonus Common Stock (Page 185)

It is a condition to Sonus' obligation to effect the transactions that Sonus receive an opinion of counsel in a form and substance reasonably satisfactory to Sonus, dated as of the closing date, to the effect that the exchange of Sonus common stock for New Solstice common stock in the Sonus merger will qualify as a reorganization under Section 368(a) of the Code or as a transaction that, taken together with the other mergers, will qualify as a transfer of property to New Solstice described in Section 351 of the Code.

Based on the tax opinion representations and assumptions (as defined under the heading "The Mergers—Material U.S. Federal Income Tax Consequences of the Sonus Merger to U.S. Holders of Sonus Common Stock—General" beginning on page 186 of this joint proxy statement/prospectus), in

44

Table of Contents

the opinion of Wilmer Cutler Pickering Hale and Dorr LLP (which we refer to as WilmerHale), the Sonus merger will qualify as a reorganization under Section 368(a) of the Code or as a transaction that, taken together with the other mergers, will qualify as a transfer of property to New Solstice described in Section 351 of the Code.

Accordingly, a U.S. holder (as defined under the heading "The Mergers—Material U.S. Federal Income Tax Consequences of the Sonus Merger to U.S. Holders of Sonus Common Stock" beginning on page 185 of this joint proxy statement/prospectus) of Sonus common stock will not recognize any gain or loss for U.S. federal income tax purposes upon the exchange of shares of Sonus common stock for shares of New Solstice common stock in the Sonus merger, except with respect to cash received in lieu of fractional shares.

Please carefully review the information set forth in the section entitled "The Mergers—Material U.S. Federal Income Tax Consequences of the Sonus Merger to U.S. Holders of Sonus Common Stock" beginning on page 185 of this joint proxy statement/prospectus for a discussion of the material U.S. federal income tax consequences of the Sonus merger to holders of Sonus common stock. Please consult your own tax advisors as to the specific tax consequences to you of the mergers.

Accounting Treatment (Page 187)

U.S. generally accepted accounting principles (which we refer to as U.S. GAAP) require the mergers to be accounted for using acquisition accounting pursuant to which Sonus has been determined to be the acquirer for accounting purposes. To make this determination, Sonus considered factors as indicated in Accounting Standards Codification (which we refer to as ASC) 805 and ASC 810, including relative ownership of equity interests in the combined company, board of director composition, shareholder ownership, voting control and anticipated management positions. Sonus will allocate the total purchase consideration to GENBAND's tangible and identifiable intangible assets acquired and liabilities assumed based on their fair values at the date of the completion of the mergers. Any excess purchase price after this allocation will be assigned to goodwill. Goodwill is not amortized, but is tested for impairment at least annually or more frequently if circumstances indicate potential impairment. The operating results of GENBAND will be reported as part of the combined company beginning on the date of the proposed mergers.

Final valuations of GENBAND's tangible and identifiable intangible assets acquired and liabilities assumed have not yet been completed. The completion of the valuation upon consummation of the mergers could result in significantly different amortization, depreciation and other expenses, revenue recognized and balance sheet classifications than those presented in the unaudited pro forma combined financial information included in this joint proxy statement/prospectus.

Litigation Related to the Mergers (Page 189)

On July 19, 2017, Taqua Holdings, LLC (which we refer to as Holdings) filed a lawsuit (which complaint we refer to as the Holdings Complaint) against Sonus, New Solstice, Solstice Merger Sub, Cayman Merger Sub, GB Merger Sub, GENBAND, GB, GB II and Taqua, LLC (which we refer to as Taqua and, collectively, we refer to these parties as the Holdings Lawsuit Defendants) in Texas state court, District of Dallas County (Case No. DC-17-08630) based on an Earn-Out Agreement, dated as of September 26, 2016, between Sonus and Holdings (which we refer to as the Earn-Out Agreement). The Holdings Complaint purports to seek monetary damages for Sonus' alleged breach of the Earn-Out Agreement and an injunction of both (i) Sonus' restructuring plans approved in connection with its acquisition of Taqua (which we refer to as the Taqua Restructuring Initiative) and (ii) the mergers. The Holdings Lawsuit Defendants believe Holdings' allegations are without merit and intend to contest the lawsuit vigorously.

RISK FACTORS

By voting in favor of the applicable merger proposal, Sonus stockholders, GENBAND shareholders, GB stockholders and GB II stockholders will be choosing to invest in New Solstice common stock following the completion of the mergers. An investment in New Solstice common stock involves a high degree of risk. Before you vote, you should carefully consider the risks described below, those described in the section entitled "Cautionary Statement Regarding Forward-Looking Statements" beginning on page 55 of this joint proxy statement/prospectus and the other information contained in this joint proxy statement/prospectus or in the documents of Sonus incorporated by reference into this joint proxy statement/prospectus, particularly the risk factors discussed in this section of this joint proxy statement/prospectus entitled "Risk Factors" and in the sections entitled "Risk Factors" in Sonus' Annual Report on Form 10-K for the fiscal year ended December 31, 2016 and Sonus' Quarterly Report on Form 10-Q for the period ended June 30, 2017, each of which is incorporated by reference into this joint proxy statement/prospectus. See the section entitled "Where You Can Find More Information" beginning on page 350 of this joint proxy statement/prospectus. In addition to the risks set forth below, new risks may emerge from time to time and it is not possible to predict all risk factors, nor can Sonus or GENBAND assess the impact of all factors on the mergers and the combined company following the mergers or the extent to which any factor or combination of factors may cause actual results to differ materially from those contained in or implied by any forward-looking statements.

Risks Relating to the Mergers

Sonus stockholders, GENBAND shareholders, GB stockholders and GB II stockholders cannot be sure of the value of the merger consideration they will be entitled to receive.

Sonus stockholders, GENBAND shareholders, GB stockholders and GB II stockholders will be entitled to receive a fixed number of shares of New Solstice common stock in the mergers, respectively, rather than a number of shares of New Solstice common stock with a particular fixed market value. The market value of Sonus common stock at the effective time may vary significantly from its price on the date prior to the date the merger agreement was executed, the date of this joint proxy statement/prospectus or the date on which Sonus stockholders, GENBAND shareholders, GB stockholders and GB II stockholders vote on the applicable merger proposals. At the time of the special meetings or extraordinary general meeting, Sonus stockholders, GENBAND shareholders, GB stockholders and GB II stockholders will not know or be able to determine the value of the New Solstice common stock they may receive upon completion of the mergers. Changes in the market price of Sonus common stock may result from a variety of factors that are beyond the control of Sonus or GENBAND, including changes in their respective businesses, operations and prospects, regulatory considerations, governmental actions, and legal proceedings and other developments. Market assessments of the benefits of the mergers, the likelihood that the mergers will be completed and general and industry-specific economic and market conditions may also have an effect on the market price of Sonus common stock. Changes in market prices of Sonus common stock may also be caused by fluctuations and developments affecting general and industry-specific economic and market conditions and may have an adverse effect on Sonus common stock prior to the consummation of the mergers.

In addition, the market value of Sonus common stock may vary significantly from the date of the special meetings to the date of the completion of the mergers. You are urged to obtain up-to-date prices for Sonus common stock. There is no assurance that the mergers will be completed, that there will not be a delay in the completion of the mergers or that all or any of the anticipated benefits of the mergers will be obtained. See the section entitled "Comparative Historical and Unaudited Pro Forma Per Share Data" for ranges of historic prices of Sonus common stock.

Table of Contents

The market price for New Solstice common stock may be affected by factors different from those that historically have affected Sonus common stock and GENBAND party shares or common stock (as applicable).

Following the mergers, Sonus stockholders, GENBAND shareholders, GB stockholders and GB II stockholders will become stockholders of New Solstice. The combined company's business will differ from that of Sonus and GENBAND, and accordingly the results of operations of New Solstice following the mergers will be affected by some factors that are different from those currently affecting the results of operations of Sonus and GENBAND. This joint proxy statement/prospectus describes the business of GENBAND and incorporates by reference important information regarding the business of Sonus and also describes important factors to consider in connection with those businesses and the business of the combined company. For a discussion of these matters, see, for example, the sections entitled "Business of GENBAND," "Management's Discussion and Analysis of the Financial Condition and Results of Operations of GENBAND," "Index to Financial Statements of GENBAND" and "Unaudited Pro Forma Condensed Combined Financial Statements" in this joint proxy statement/prospectus as well as the section entitled "Where You Can Find More Information" beginning on page 350 of this joint proxy statement/prospectus for the location of information incorporated by reference into this joint proxy statement/prospectus.

The shares of New Solstice common stock to be received by Sonus stockholders, GENBAND shareholders, GB stockholders and GB II stockholders as a result of the mergers will have different rights from shares of Sonus common stock and GENBAND party shares or common stock (as applicable).

Following completion of the mergers, Sonus stockholders, GENBAND shareholders, GB stockholders and GB II stockholders will no longer be stockholders or shareholders of Sonus and the GENBAND parties (as applicable), but will instead be stockholders of New Solstice. There will be important differences between your current rights as a Sonus stockholder, GENBAND shareholder, GB stockholder or GB II stockholder and your rights as a New Solstice stockholder. See the section entitled "Comparison of Stockholder Rights" beginning on page 294 of this joint proxy statement/prospectus.

Obtaining required regulatory approvals may prevent or delay completion of the mergers or reduce the anticipated benefits of the mergers or may require changes to the structure or terms of the mergers.

Consummation of the mergers is conditioned upon, among other things, the expiration or termination of the waiting period (and any extensions thereof) applicable to the mergers under the HSR Act. Even though on June 29, 2017, the FTC granted early termination of the applicable waiting period under the HSR Act, effective immediately, at any time before or after the mergers are consummated, any of the DOJ, the FTC or U.S. state attorneys general could take action under the antitrust laws in opposition to the mergers, including seeking to enjoin completion of the mergers, condition completion of the mergers upon the divestiture of certain assets of Sonus, GENBAND or their subsidiaries or impose restrictions on New Solstice's post-merger operations. In addition, non-U.S. agencies could take similar action under their antitrust laws in opposition to the mergers. These actions could negatively affect the results of operations and financial condition of the combined company following completion of the mergers. Any such requirements or restrictions may prevent or delay completion of the mergers or may reduce the anticipated benefits of the mergers, which could also have a material adverse effect on the combined company's business and cash flows, financial condition and results of operations. See the sections entitled "The Mergers—Regulatory Matters Relating to the Transactions" and "The Merger Agreement—Conditions to the Mergers" beginning on pages 184 and 207, respectively, of this joint proxy statement/prospectus.

Table of Contents

The closing of the mergers is subject to many conditions and if these conditions are not satisfied or waived, the mergers will not be completed.

The closing of the mergers is subject to a number of conditions as set forth in the merger agreement that must be satisfied or waived, including, among others: (i) receipt of the Sonus stockholder approval, GENBAND shareholder approval, GB stockholder approval and GB II stockholder approval; (ii) the authorization for listing by NASDAQ of the New Solstice common stock to be issued as consideration in the mergers; (iii) the expiration or termination of the HSR waiting period; (iv) the absence of any law or order from any court or governmental entity prohibiting or making unlawful the consummation of the transactions contemplated by the merger agreement; (v) the effectiveness of the registration statement on Form S-4 of which this joint proxy statement/prospectus forms a part; and (vi) the receipt by Sonus and GENBAND of certain tax opinions.

The closing of the mergers is also dependent upon the accuracy of representations and warranties made by the parties to the merger agreement (subject to customary materiality qualifiers and other customary exceptions) and the performance in all material respects by the parties of obligations imposed under the merger agreement.

For a more complete summary of the conditions that must be satisfied or waived prior to completion of the mergers, see the section entitled "The Merger Agreement—Conditions to the Mergers" beginning on page 207 of this joint proxy statement/prospectus.

There can be no assurance as to whether or when the conditions to the closing of the mergers will be satisfied or waived or as to whether or when the mergers will be consummated.

The opinions of Sonus' and GENBAND's financial advisors will not reflect changes in circumstances between the signing of the merger agreement and the completion of the mergers.

GENBAND has not obtained an updated opinion from its financial advisor in respect of the consideration to be paid to GENBAND party shareholders in connection with the mergers as of the date of this joint proxy statement/prospectus and does not expect to receive an updated opinion prior to the completion of the mergers. Sonus received an updated opinion as a result of revised estimates furnished by management of Sonus of the present value of net operating losses of Sonus and the GENBAND parties on June 22, 2017, but otherwise has not obtained an updated opinion from its financial advisor in respect of the consideration to be paid to Sonus stockholders in connection with the mergers as of the date of this joint proxy statement/prospectus and does not expect to receive an updated opinion prior to the completion of the mergers. Changes in the operations and prospects of Sonus or GENBAND, general market and economic conditions and other factors that may be beyond the control of Sonus or GENBAND, and on which the opinion of their respective financial advisors was based, may significantly alter the value of Sonus or GENBAND, or the price of Sonus common stock, by the time the mergers are completed. The opinions do not speak as of the time the mergers will be completed or as of any date other than the date of the opinion. Because the financial advisors will not be updating their opinions, which were issued in connection with the execution of the merger agreement on May 23, 2017 (and, with respect to Sonus, as updated solely as described above), the opinions will not address the fairness of the merger consideration from a financial point of view at the time the mergers are completed. The recommendation of the Sonus board that Sonus stockholders vote "FOR" each of the proposals to be considered at the Sonus special meeting, and the recommendation of the GENBAND board that GENBAND shareholders vote "FOR" each of the proposals to be considered at the Extraordinary General Meeting, however, are made as of the date of this joint proxy statement/prospectus. For a description of the opinions that Sonus and GENBAND received from their respective financial advisors, see the sections entitled "The Mergers—Opinion of Sonus' Financial Advisor" and "The Mergers—Opinion of GENBAND's Financial Advisor" beginning on pages 133 and 153, respectively, of this joint proxy statement/prospectus.

Table of Contents

Sonus and the GENBAND parties will be subject to business uncertainties and certain operating restrictions until consummation of the mergers.

Uncertainty about the effect of the mergers on employees and customers, among others, may have an adverse effect on Sonus, the GENBAND parties or the combined company following the mergers. These uncertainties could disrupt the business of Sonus or the GENBAND parties and cause customers, suppliers, vendors, partners and others that deal with Sonus and the GENBAND parties to defer entering into contracts with Sonus and the GENBAND parties or making other decisions concerning Sonus and the GENBAND parties or seek to change or cancel existing business relationships with Sonus and the GENBAND parties. Retention and motivation of certain employees may be challenging during the pendency of the mergers due to uncertainty about their future roles and difficulty of integration. If key employees depart because of issues related to the uncertainty and difficulty of integration or a desire not to remain with the combined company, New Solstice's business following the mergers could be negatively impacted. In addition, the merger agreement restricts the parties thereto from making certain acquisitions and investments and taking other specified actions until the merger occurs without the consent of the other party. These restrictions may prevent Sonus and the GENBAND parties from pursuing attractive business opportunities that may arise prior to the completion of the mergers. See the section entitled "The Merger Agreement—Covenants and Agreements" beginning on page 199 of this joint proxy statement/prospectus for a description of the restrictive covenants to which each of Sonus and the GENBAND parties is subject.

The merger agreement contains restrictions on the ability of Sonus to pursue other alternatives to the mergers.

The merger agreement contains non-solicitation provisions that, subject to limited exceptions, restrict the ability of Sonus to maintain, initiate, solicit or knowingly encourage or facilitate any Sonus acquisition proposal (as defined under the heading "The Merger Agreement—No Solicitation—No Solicitation by Sonus" beginning on page 201 of this joint proxy statement/prospectus) or any inquiry or proposal that would reasonably be expected to lead to a Sonus acquisition proposal from any third party, or participate in any discussions or negotiations regarding any acquisition proposal or any inquiry or proposal that would reasonably be expected to lead to a Sonus acquisition proposal. Although the Sonus board is permitted to take certain actions in response to a superior proposal (as defined under the heading "The Merger Agreement—No Solicitation—No Solicitation by Sonus" beginning on page 201 of this joint proxy statement/prospectus) or a Sonus acquisition proposal that is reasonably likely to result in a superior proposal if it determines that the failure to do so would be reasonably likely to be inconsistent with its fiduciary duties, doing so in specified situations could require Sonus to pay to GENBAND a termination fee of $14.5 million. See the sections entitled "The Merger Agreement—No Solicitation—No Solicitation by Sonus" beginning on page 201 of this joint proxy statement/prospectus and "The Merger Agreement—Termination Fee" beginning on page 211 of this joint proxy statement/prospectus for a more complete discussion of these restrictions and consequences.

Such provisions could discourage a potential acquiror that might have an interest in making a proposal from considering or proposing any such transaction, even if it were prepared to pay consideration with a higher value to Sonus stockholders than that to be paid in the mergers. There also is a risk that the requirement to pay the termination fee to GENBAND in certain circumstances may result in a potential acquiror proposing to pay a lower per share price to acquire Sonus than it might otherwise have proposed to pay.

The merger agreement contains restrictions on the ability of GENBAND to pursue other alternatives to the mergers.

The merger agreement contains non-solicitation provisions that restrict the ability of GENBAND to maintain, initiate or solicit or knowingly encourage or facilitate any GENBAND acquisition proposal (as defined under the heading "The Merger Agreement—No Solicitation—No Solicitation by

GENBAND Parties" beginning on page 203 of this joint proxy statement/prospectus) or any inquiry or proposal that would reasonably be expected to lead to a GENBAND acquisition proposal from any third party, or participate in any negotiations regarding any acquisition proposal or any inquiry or proposal that would reasonably be expected to lead to a GENBAND acquisition proposal. Such provisions could discourage a potential acquiror that might have an interest in making a proposal from considering or proposing any such transaction, even if it were prepared to pay consideration with a higher value to the GENBAND party shareholders than that to be paid in the mergers.

The merger agreement may be terminated in accordance with its terms and the mergers may not be completed.

Sonus or GENBAND may terminate the merger agreement under certain circumstances including, among other reasons, if the merger is not completed by February 23, 2018 or, if extended by either Sonus or GENBAND in accordance with the terms of the merger agreement, May 31, 2018. For a discussion of the circumstances under which the merger agreement could be terminated and when a termination fee may be payable by Sonus, see the sections entitled "The Merger Agreement—No Solicitation" and "The Merger Agreement—Termination Fee" beginning on pages 201 and 211, respectively, of this joint proxy statement/prospectus.

The termination of the merger agreement could negatively impact Sonus and GENBAND.

If the mergers are not completed for any reason, including as a result of the Sonus stockholder approval, the GENBAND shareholder approval, the GB stockholder approval or the GB II stockholder approval not being obtained, the ongoing businesses of Sonus and GENBAND may be adversely affected and, without realizing any of the anticipated benefits of having completed the mergers, Sonus and GENBAND would be subject to a number of risks, including the following:

•
  Sonus may experience negative reactions from the financial markets, including a decline of its stock price (which may reflect a market assumption that the mergers will be completed);
•
  Sonus and GENBAND may experience negative reactions from their respective customers, regulators and employees;
•
  Sonus and GENBAND could be subject to litigation related to a failure to complete the mergers or perform their respective obligations under the merger agreement;
•
  Sonus and GENBAND will be required to pay certain costs relating to the mergers, whether or not the mergers are completed; and
•
  matters relating to the mergers (including integration planning) will require substantial commitments of time and resources by Sonus management and GENBAND management, which would otherwise have been devoted to day-to-day operations and other opportunities that may have been beneficial to Sonus and GENBAND as independent companies.

If the merger agreement is terminated and the Sonus board or the GENBAND board seeks another merger, business combination or other transaction, Sonus stockholders or GENBAND party shareholders (as applicable) cannot be certain that Sonus or GENBAND will be able to find a party willing to offer equivalent or more attractive consideration than the consideration Sonus stockholders and GENBAND party shareholders (as applicable) would receive in the mergers. If the merger agreement is terminated under certain circumstances specified in the merger agreement, Sonus may be required to pay GENBAND a termination fee of $14.5 million, depending on the circumstances surrounding the termination. See the section entitled "The Merger Agreement—Termination Fee" beginning on page 211 of this joint proxy statement/prospectus for a more complete discussion of the circumstances under which the merger agreement could be terminated and when the termination fee may be payable by Sonus.

If the mergers are not consummated, Sonus cannot assure its stockholders that the risks described will not materially affect the business, financial results and stock price of Sonus.

Directors and executive officers of Sonus and the GENBAND parties have interests in the mergers, including accelerated vesting of equity awards, that are different from, and in addition to, those of Sonus stockholders and GENBAND party shareholders who are not directors or executive officers of Sonus or the GENBAND parties.

Certain of the directors and executive officers of each of Sonus and the GENBAND parties negotiated the terms of the merger agreement, the Sonus board recommended that Sonus stockholders vote in favor of the Sonus merger proposal, the Sonus governance-related proposals and the Sonus executive compensation proposal, and each GENBAND party board recommended that the applicable GENBAND party shareholders vote in favor of the applicable merger proposal. These directors and executive officers have interests in the mergers, which are different from, or in addition to, or in conflict with, those of Sonus stockholders and GENBAND party shareholders who are not directors or executive officers of Sonus or the GENBAND parties. These interests include the continued service of certain directors of Sonus and the GENBAND parties as directors of the combined company, acceleration of vesting of stock options, restricted stock units, performance stock units, profits interests and other equity-based awards, potential severance payments and continued medical and welfare benefits for certain Sonus and GENBAND party executive officers and directors, continuing employment of certain executive officers of Sonus and GENBAND by the combined company, certain other one-time and retention and similar bonus payments for certain executive officers and directors of Sonus and the GENBAND parties, certain equity grants in New Solstice for certain executive officers and directors of the GENBAND parties, and certain indemnification rights for executive officers and directors of Sonus and the GENBAND parties.

Sonus stockholders and GENBAND party shareholders who are not directors or executive officers of Sonus or the GENBAND parties should be aware of these interests when they consider recommendations of the respective Sonus and GENBAND party boards that they vote in favor of the Sonus merger proposal, the Sonus governance-related proposals and the Sonus executive compensation proposal, or the applicable GENBAND party merger proposal, as applicable. The Sonus board was aware of these interests when it determined that the merger agreement and the transactions contemplated thereby were advisable and fair to, and in the best interests of, the Sonus stockholders and recommended that the Sonus stockholders adopt the merger agreement. The interests of Sonus directors and executive officers, including the number and value of equity awards that will be accelerated, are described in more detail in the section entitled "The Mergers—Interests of Directors and Executive Officers in the Transactions—Interests of Directors and Executive Officers of Sonus in the Transactions" and "The Merger Agreement—Treatment of Sonus Equity Awards." Likewise, each GENBAND party board was aware of these interests when it determined that the merger agreement and the transactions contemplated thereby were advisable and fair to, and in the best interests of, the respective GENBAND party shareholders and recommended that the applicable GENBAND party shareholders adopt the merger agreement. The interests of GENBAND party directors and executive officers, including the accelerated vesting of certain equity awards and eligibility for certain additional equity-based payments, are described in more detail in the section entitled "The Mergers—Interests of Directors and Executive Officers in the Transactions—Interests of Directors and Executive Officers of the GENBAND Parties in the Transactions."

The unaudited pro forma condensed combined financial statements included in this joint proxy statement/prospectus are presented for illustrative purposes only and the actual financial condition and results of operations of the combined company following the mergers may differ materially.

The unaudited pro forma condensed combined financial statements contained in this joint proxy statement/prospectus are presented for illustrative purposes only, are based on various adjustments, assumptions and preliminary estimates, and may not be an indication of financial condition or results of operations of the combined company following the mergers for several reasons. The actual financial condition and results of operations of the combined company following the mergers may not be consistent with, or evident from, these unaudited pro forma condensed combined financial statements. In addition, the assumptions used in preparing the unaudited pro forma condensed combined financial statements may not prove to be accurate, and other factors may affect the combined company's financial condition or results of operations following the mergers. Any potential decline in the combined company's financial condition or results of operations may cause significant variations in the stock price of New Solstice following the closing of the mergers.

Both Sonus stockholders and GENBAND party shareholders will have a reduced ownership and voting interest after the mergers and will exercise less influence over management.

After the completion of the mergers, former Sonus stockholders and former GENBAND party shareholders will own a smaller percentage of New Solstice than they currently own of Sonus or GENBAND, GB or GB II, respectively. Upon completion of the mergers, former Sonus stockholders, on the one hand, and former GENBAND shareholders, GB stockholders and GB II stockholders, on the other hand, in the aggregate each will hold approximately 50% of the shares of New Solstice common stock issued and outstanding immediately after the consummation of the mergers. Consequently, Sonus stockholders, as a group, and GENBAND party shareholders, as a group, will each have reduced ownership and voting power in the combined company compared to their ownership and voting power in Sonus and GENBAND, GB and GB II, respectively.

Consideration to be received by GENBAND shareholders, GB stockholders and GB II stockholders is subject to the liquidation waterfall as set forth in Article 5.2 of the GENBAND Articles of Association attached as Annex C to this joint proxy statement/prospectus.

As further described in the section entitled "The Mergers—Consideration to be Received in Connection with the Transactions Contemplated by the Merger Agreement—GENBAND Party Mergers" beginning on page 108 of this joint proxy statement/prospectus, the distribution of merger consideration to the holders of GENBAND shares, GB common stock and GB II common stock is subject to the liquidation waterfall as set forth in Article 5.2 of the GENBAND Articles of Association attached as Annex C to this joint proxy statement/prospectus. The consideration amount distributed to the shareholders of the GENBAND parties is to be calculated according to this waterfall and, depending on the value of the final total consideration on the closing date of the mergers, the merger consideration distributed to certain shareholders may be zero. Under the merger agreement, GENBAND shareholders (other than GB and GB II) will also have the right to receive a three-year promissory note issued by New Solstice as described in the section entitled "The Mergers—Consideration to be Received in Connection with the Transactions Contemplated by the Merger Agreement—GENBAND Merger" beginning on page 107 of this joint proxy statement/prospectus. Consideration from the promissory note will be distributed to GENBAND shareholders (other than GB and GB II) in accordance with the waterfall. Pursuant to the terms of the merger agreement, GB and GB II stockholders are not entitled to receive any consideration under the promissory note.

Table of Contents

Risks Relating to the Combined Company Following the Mergers

New Solstice may fail to realize the anticipated benefits of the mergers.

The success of the mergers will depend on, among other things, New Solstice's ability to combine the businesses of Sonus and GENBAND in a manner that facilitates growth opportunities and realizes the anticipated benefits, including, without limitation the anticipated synergies and cost savings, from combining the businesses of Sonus and GENBAND, as further described in the sections entitled "The Mergers—Recommendation of the Sonus Board; Sonus' Reasons for the Mergers" beginning on page 123 of this joint proxy statement/prospectus and "The Mergers—Recommendation of the GENBAND Board," "—Recommendation of the GB Board," "—Recommendation of the GB II Board" and "—Reasons of GENBAND, GB and GB II for the Transactions" beginning on pages 166, 166, 167 and 167, respectively, of this joint proxy statement/prospectus.

However, New Solstice must successfully combine the businesses of Sonus and GENBAND in a manner that permits these anticipated benefits to be realized. In addition, the combined company must achieve the anticipated synergies and cost savings without adversely affecting current revenues and investments in future growth. If the combined company is not able to successfully achieve these objectives, the anticipated benefits of the mergers may not be realized fully, or at all, or may take longer to realize than expected.

Failure to successfully combine the businesses of Sonus and GENBAND in the expected time frame may adversely affect New Solstice's future results.

Historically, Sonus and GENBAND have been independent companies, and they will continue to be operated as such until the completion of the transactions contemplated by the merger agreement, including the mergers. There can be no assurance that their businesses can be integrated successfully. The management of New Solstice may face significant challenges in consolidating the functions of Sonus and GENBAND, integrating the technologies, organizations, procedures, policies and operations, as well as addressing the different business cultures at the two companies, and retaining key personnel. The integration may also be complex and time consuming, and require substantial resources and effort. The integration process and other disruptions resulting from the mergers may also disrupt each company's ongoing business and/or adversely affect each company's relationships with its employees, regulators and customers and others with whom such company has business or other dealings. In addition, difficulties in integrating the businesses could harm the reputation of New Solstice.

Combining the businesses of Sonus and GENBAND may be more difficult, costly or time-consuming than expected, which may adversely affect the combined company's results and negatively affect the value of its common stock following the mergers.

Sonus and GENBAND have entered into the merger agreement because each believes that the mergers will be beneficial to its respective companies and stockholders and that combining the businesses of Sonus and GENBAND will produce benefits and cost savings. If the combined company is not able to successfully combine the businesses of Sonus and GENBAND in an efficient and effective manner, the anticipated benefits and cost savings of the mergers may not be realized fully, or at all, or may take longer to realize than expected, and the value of New Solstice common stock may be affected adversely.

An inability to realize the full extent of the anticipated benefits of the mergers and the other transactions contemplated by the merger agreement, as well as any delays encountered in the integration process, could have an adverse effect upon the revenues, level of expenses and operating results of the combined company, which may adversely affect the value of New Solstice common stock following the mergers.

64

Table of Contents

In addition, the actual integration may result in additional and unforeseen expenses, and the anticipated benefits of the integration plan may not be realized. Actual growth and cost savings, if achieved, may be lower than what the combined company expects and may take longer to achieve than anticipated. If New Solstice is not able to adequately address integration challenges, the combined company may be unable to successfully integrate Sonus' and GENBAND's operations or realize the anticipated benefits of the integration of the two companies.

Sonus and GENBAND will incur significant transaction and merger-related costs in connection with the mergers, which may adversely affect the liquidity of the combined company.

Sonus and GENBAND have incurred, and expect that they and New Solstice will incur, significant, non-recurring costs in connection with consummating the mergers and integrating the operations of the two companies. Sonus and GENBAND may incur additional costs to maintain employee morale and to retain key employees. Sonus and GENBAND will also incur significant fees and expenses relating to legal, accounting and other transaction fees and other costs associated with the mergers. Some of these costs are payable by Sonus and GENBAND regardless of whether or not the mergers are completed. Moreover, under specified circumstances, Sonus may be required to pay to GENBAND a termination fee of $14.5 million if the mergers are not consummated. See the section entitled "The Merger Agreement—Termination Fee" beginning on page 211 of this joint proxy statement/prospectus.

There is also a large number of processes, policies, procedures, operations, technologies and systems that must be integrated in connection with the mergers and the integration of the two companies' businesses. While both Sonus and GENBAND have assumed that a certain level of expenses would be incurred in connection with the mergers and the other transactions contemplated by the merger agreement, there are many factors beyond their control that could affect the total amount or the timing of the integration and implementation expenses.

There may also be additional unanticipated significant costs and charges in connection with the mergers that the combined company may not recoup. These costs and expenses could reduce the realization of efficiencies, strategic benefits and additional income Sonus and GENBAND expect to achieve from the mergers. Although Sonus and GENBAND expect that these benefits will offset the transaction expenses and implementation costs over time, this net benefit may not be achieved in the near term or at all.

Sonus' credit facility expired by its terms on June 30, 2017 and was not renewed. Accordingly, it is expected that New Solstice will pay the costs and charges described above from available cash on hand or borrowings under any credit facility that New Solstice may be able to obtain in the future. Payment of these costs and charges may adversely affect the liquidity of the combined company, and there can be no assurance that New Solstice will be able to obtain a credit facility on acceptable terms prior to the completion of the mergers or at all.

Third parties may terminate or alter existing contracts or relationships with Sonus or GENBAND.

Sonus and GENBAND have contracts with customers, suppliers, vendors, landlords, licensors and other business partners which may require Sonus or GENBAND to obtain consents from these other parties in connection with the mergers. If these consents cannot be obtained, Sonus or GENBAND may suffer a loss of potential future revenues and may lose rights that are material to their respective businesses and the business of the combined company. In addition, third parties with whom Sonus or GENBAND currently have relationships may terminate or otherwise reduce the scope of their relationship with either party in anticipation of the mergers. Any such disruptions could limit the combined company's ability to achieve the anticipated benefits of the mergers. The adverse effect of such disruptions could also be exacerbated by a delay in the completion of the mergers or the termination of the merger agreement.

65

Table of Contents

The combined company may be unable to retain Sonus and/or GENBAND key employees successfully after the mergers are completed.

The success of the mergers will depend in part on the combined company's ability to retain the talents and dedication of key employees currently employed by Sonus and GENBAND. It is possible that these employees may decide not to remain with Sonus or GENBAND, as applicable, while the mergers are pending or with the combined company after the mergers are consummated. If key employees terminate their employment, or if an insufficient number of employees is retained to maintain effective operations, the combined company's business activities may be adversely affected and management's attention may be diverted from successfully integrating the businesses of Sonus and GENBAND to hiring suitable replacements, all of which may cause the combined company's business to suffer. In addition, Sonus and GENBAND may not be able to locate suitable replacements for any key employees who leave either company or offer employment to potential replacements on reasonable terms.

New Solstice will enter into a stockholders agreement with certain of the GENBAND party shareholders, which provides them with certain rights over company matters.

The merger agreement contemplates that, as an additional condition to the closing of the transactions contemplated by the merger agreement, at the closing, New Solstice will enter into a stockholders agreement with the OEP Stockholders. The stockholders agreement will establish certain rights, restrictions and obligations of New Solstice and the OEP Stockholders, and will set forth other arrangements relating to New Solstice, including the right of the OEP Stockholders to designate up to five directors for nomination to New Solstice's nine member board of directors, subject to the OEP Stockholders maintaining certain beneficial ownership of New Solstice common stock. Therefore, the OEP Stockholders will be able to exert significant influence over matters requiring board approval, and New Solstice stockholders other than the OEP Stockholders will have limited or no ability to influence the outcome of certain key transactions.

The interests of the parties to the stockholders agreement may differ from those of other holders of New Solstice common stock. See the section entitled "Other Related Agreements—Principal Stockholders Agreement" beginning on page 214 of this joint proxy statement/prospectus.

Risks Relating to Ownership of New Solstice Common Stock

Because there is currently no public market for New Solstice common stock, the market price and trading volume of New Solstice common stock may be volatile, and holders may not be able to sell shares of New Solstice common stock following the mergers.

Prior to the completion of the mergers, New Solstice common stock will not be publicly traded and there will not have been any public market for New Solstice common stock. Following the completion of the mergers, an active trading market for the New Solstice common stock may not develop or be sustained. As a result, no public market price is available to Sonus stockholders or GENBAND party shareholders for use in determining the value of New Solstice common stock they are entitled to receive as merger consideration. We cannot predict the extent to which investor interest will lead to the development of an active trading market in shares of New Solstice common stock or whether such a market will be sustained following the mergers.

The market price of New Solstice common stock after the completion of the mergers will be subject to significant fluctuations in response to, among other factors, variations in operating results and market conditions specific to the combined company's industry. If an active trading market does not develop or is not sustained, it may be difficult for you to sell your shares at a price that is attractive

66

Table of Contents

to you, or at all. The market price of New Solstice common stock could fluctuate significantly for many reasons, including, without limitation:

•
  as a result of the risk factors listed in this joint proxy statement/prospectus;
•
  actual or anticipated fluctuations in the combined company's operating results;
•
  for reasons unrelated to operating performance, such as reports by industry analysts, investor perceptions, or negative announcements by the combined company's customers or competitors regarding their own performance;
•
  regulatory changes that could impact the combined company's business; and
•
  general economic and industry conditions.

Future sales of New Solstice common stock in the public market could cause volatility in the price of New Solstice common stock or cause the share price to fall.

Sales of a substantial number of shares of New Solstice common stock in the public market, or the perception that these sales might occur, could depress the market price of New Solstice common stock, and could impair New Solstice's ability to raise capital through the sale of additional equity securities.

The merger agreement provides that New Solstice and the OEP Stockholders will enter into a registration rights agreement requiring New Solstice to register for resale under the Securities Act of 1933, as amended (which we refer to as the Securities Act), all registrable shares held by the OEP Stockholders. As of the closing date, registrable shares will represent approximately [ ]% of the outstanding stock of New Solstice on a fully diluted basis. Accordingly, sales of a large number of registrable shares may be made after the closing of the mergers upon registration of such shares with the SEC in accordance with the terms of the registration rights agreement. Registration and sales of New Solstice common stock effected pursuant to the registration rights agreement will increase the number of shares being sold in the public market and may increase the volatility of the price of New Solstice common stock. See the section entitled "Other Related Agreements—Registration Rights Agreement" beginning on page 216 of this joint proxy statement/prospectus.

The mergers may not be accretive and may cause dilution to New Solstice's earnings per share, which may negatively affect the market price of New Solstice's common stock.

Sonus and GENBAND currently anticipate that the mergers will be accretive to earnings per share of New Solstice in fiscal year 2018, after adjusting for, among other things, stock-based compensation, amortization of intangible assets, acquisition-related expense, restructuring, certain gains and losses included in other income (expense) and deferred income tax adjustments. This expectation is based on preliminary estimates, which may materially change. New Solstice could also encounter additional transaction and integration-related costs or other factors, such as the failure to realize all of the benefits anticipated in the mergers. All of these factors could cause dilution to New Solstice's adjusted earnings per share or decrease or delay the expected accretive effect of the mergers and cause a decrease in the market value of New Solstice's common stock.

Charges to earnings resulting from the application of the purchase method of accounting may adversely affect the market value of New Solstice common stock following the mergers.

In accordance with U.S. GAAP, Sonus will be considered the acquirer of GENBAND for accounting purposes. Sonus will account for the mergers using the purchase method of accounting, which will result in charges to New Solstice's earnings that could adversely affect the market value of New Solstice common stock following the completion of the mergers. Under the purchase method of accounting, Sonus will allocate the total purchase price to the assets acquired and liabilities assumed

67

Table of Contents

from GENBAND based on their fair values as of the date of the completion of the mergers, and record any excess of the purchase price over those fair values as goodwill. For certain tangible and intangible assets, reevaluating their fair values as of the completion date of the mergers will result in New Solstice incurring additional depreciation and/or amortization expense that exceeds the combined amounts recorded by Sonus and GENBAND prior to the mergers. In addition, adjustments to other assets and liabilities, including inventory and deferred revenue, could result in higher cost of sales and lower amounts of revenue recognized in the near term resulting from these adjustments. These increased expenses will be recorded by New Solstice over the useful lives of the underlying assets. The reductions to revenue recognized will be recorded until the related deferred revenue is converted to revenue. In addition, to the extent the value of goodwill or intangible assets were to become impaired, New Solstice may be required to incur charges relating to the impairment of those assets. See the section entitled "The Mergers—Accounting Treatment" beginning on page 187 of this joint proxy statement/prospectus.

Risks Relating to Sonus' Business

You should read and consider risk factors specific to Sonus' business that may also affect the combined company after the mergers. These risks are described in the section entitled "Risk Factors" in Sonus' Quarterly Report on Form 10-Q for the period ended June 30, 2017, and in other documents incorporated by reference into this joint proxy statement/prospectus. See the section entitled "Where You Can Find More Information" beginning on page 350 of this joint proxy statement/prospectus for the location of information incorporated by reference into this joint proxy statement/prospectus.

Risks Relating to the GENBAND Parties' Business

You should read and consider the following risk factors specific to the GENBAND parties' business that may also affect the combined company after the mergers.

Failure by GENBAND's strategic partners or by GENBAND in integrating products provided by its strategic partners could harm its business.

GENBAND's solutions include the integration of products supplied by strategic partners who offer complementary products and services. GENBAND relies on these strategic partners in the timely and successful deployment of its solutions to its customers. If the products provided by these partners have defects or do not operate as expected, if the services provided by these partners are not completed in a timely manner, if GENBAND's partners have organizational or supply issues, or if GENBAND does not effectively integrate and support products supplied by these strategic partners, then GENBAND may have difficulty with the deployment of its solutions that may result in loss of, or delay in, revenues and/or increased service, support and warranty costs and a diversion of development resources, as well as network performance penalties.

In addition to cooperating with GENBAND's strategic partners on specific customer projects, GENBAND also may compete in some areas with these same partners. If these strategic partners fail to perform or choose not to cooperate with GENBAND on certain projects, in addition to the effects described above, GENBAND could experience loss of customers and market share and/or failure to attract new customers or achieve market acceptance for GENBAND's products.

If GENBAND's strategic plan is not aligned with the direction its customers take as they invest in the evolution of their networks, customers may not buy GENBAND's products or use its services. New product launches or acquired products may reduce GENBAND's earnings or generate losses.

As technology advances, GENBAND may not be able to respond quickly or effectively to developments in the market for its products, or new industry standards may emerge and could render

68

Table of Contents

its existing or future products and services obsolete. GENBAND's future success will depend in part on its ability to continue offering new products and services that successfully gain market acceptance by addressing the needs of its current and future customers. In order to be successful, GENBAND's technologies, products and solutions must be accepted by relevant standardization bodies and by the industry as a whole. GENBAND spends a significant amount of resources developing new technology and products. GENBAND's strategic plan includes a significant shift in its investments from mature technologies toward certain next-generation technologies. GENBAND's choices of specific technologies to pursue may prove to be inconsistent with its customers' investment spending. Its success also depends upon its ability to integrate new and acquired products and services and to enhance its existing products and services. If GENBAND invests in the development of technologies, products and solutions that do not operate as expected, are not ready in time, are not adopted by the industry or by its customers or are unsuccessful in the marketplace, GENBAND's revenue and earnings may suffer. If GENBAND's products and services become technologically obsolete or if it is unable to develop successor products and services that are accepted by its customers, it may be unable to sell its products and services to customers and face declines in revenues and earnings.

If GENBAND does not meet specific customer requirements or if its products do not interoperate with GENBAND customers' existing networks, GENBAND may not be successful in retaining current or attracting new customers.

To achieve market acceptance for GENBAND's products, GENBAND must adapt in a timely manner to customer requirements and offer products and services that meet shifting demands of its current and prospective customers. Prospective customers may require certain product features and capabilities that GENBAND's current products do not have. The introduction of new or enhanced products also requires that GENBAND carefully manage the transition from older products in order to minimize disruption in customer ordering patterns and ensure that adequate supplies of new products can be delivered to meet anticipated customer demand. If GENBAND fails to develop products and offer services that satisfy customer requirements or if GENBAND fails to effectively manage the transition from older products, its ability to create or increase demand for its products and services could be materially diminished and GENBAND may lose current and prospective customers.

Many of GENBAND's customers will require that GENBAND's products be designed to interface with their existing networks, each of which may have different specifications. Issues caused by an unanticipated lack of interoperability may result in significant warranty and repair costs and cause significant customer relations problems. If GENBAND's products do not interoperate with those of its customers' networks, installations or orders for its products could be delayed or cancelled, which may seriously harm GENBAND's gross margins and result in loss of customers or revenues. Furthermore, GENBAND's customers may decide to devote a significant portion of their budgets to evolving technology as they consider national or worldwide expansion. Accordingly, if demand for GENBAND's products is weak and if its target customers do not adopt, purchase and successfully deploy GENBAND's current or planned products, GENBAND's revenues will not increase.

GENBAND's large customers have substantial negotiating leverage, and they may require that GENBAND agree to terms and conditions that may have an adverse effect on GENBAND's business.

Large communications service providers have substantial purchasing power and leverage in negotiating contractual arrangements with GENBAND. These customers may, among other things, require GENBAND to develop additional features, require penalties for failure to deliver such features, require GENBAND to partner with a certain reseller before purchasing its products and/or seek discounted product and/or service pricing. As GENBAND sells more products to this class of customer, it may be required to agree to terms and conditions that are less beneficial, which may affect

69

Table of Contents

the timing of revenue recognition, amount of deferred revenues or product and service margins and may adversely affect its financial position and cash flows in certain reporting periods.

The market for some of GENBAND's products depends on the availability and demand for other vendors' products.

Some of GENBAND's products are designed to function with other vendors' products. In these cases, demand for its products is dependent upon the availability, demand for, and sales of the other vendors' products, as well as the degree to which its products successfully interoperate with the other vendors' products and add value to the solution being provided to the customer. If the other vendors change the design of their products, delay the issuance of new releases, fail to adequately market their products, or are otherwise unsuccessful in building a market for their products, the demand for GENBAND's products will be adversely affected.

If GENBAND is not able to obtain necessary licenses or ongoing maintenance and support of third-party technology at acceptable prices, on acceptable terms, or at all, it could harm GENBAND's operating results or business.

GENBAND has incorporated third-party licensed technology, including open source software, into GENBAND's current products. From time to time, GENBAND may be required to license additional technology from third parties to develop new products or product enhancements.

Third-party licenses and ongoing maintenance and support may not be available or continue to be available to GENBAND on commercially reasonable terms or may be available to GENBAND but only at significantly escalated pricing. Additionally, GENBAND may not be able to replace the functionality provided by third-party software currently offered with its products if that software becomes obsolete, defective or incompatible with future versions of its products or is not adequately maintained or updated. The inability to maintain or re-license any third-party licenses required in GENBAND's current products or to obtain any new third-party licenses to develop new products and product enhancements could require GENBAND to obtain substitute technology of lower quality or performance standards or at greater cost, and delay or prevent GENBAND from making these products or enhancements, any of which could seriously harm the competitiveness of GENBAND's products. Any significant interruption in the availability of these third-party software products or defects in these products could harm GENBAND's sales unless and until GENBAND can secure an alternative source. Although GENBAND believes there are adequate alternate sources for the technology licensed to it, such alternate sources may not provide GENBAND with the same functionality as that currently provided to it.

GENBAND tests its products before they are deployed. However, because its larger scale products are sophisticated and designed to be deployed in complex networks, they may have errors or defects that it finds only after full deployment, which could seriously harm GENBAND's business.

GENBAND's larger scale products are sophisticated and are designed to be deployed in large and complex networks. GENBAND tests its products before they are deployed. However, because of the nature of GENBAND's products, they can only be fully tested when substantially deployed in very large networks with high volumes of traffic. Some of GENBAND's customers may discover errors or defects in the software or hardware, or the products may not operate as expected after full deployment. As GENBAND continues to expand GENBAND's distribution channel through distributors and resellers, GENBAND will need to rely on and support their service and support organizations. If GENBAND is unable to fix errors or other performance problems that may be identified after full deployment of its products, GENBAND could experience loss of, or delay in, revenues or increased expense; loss of customers and market share; failure to attract new customers or achieve market acceptance for

70

Table of Contents

GENBAND's products; increased service, support and warranty costs and a diversion of development resources; and/or costly and time-consuming legal actions by GENBAND's customers.

Because GENBAND's larger scale products are deployed in large, complex networks around the world, failure to establish a support infrastructure and maintain required support levels could seriously harm its business.

GENBAND's larger scale products are deployed in large and complex networks around the world. GENBAND's customers expect GENBAND to establish a support infrastructure and maintain demanding support standards to ensure that their networks maintain high levels of availability and performance. To continue to support GENBAND's customers with these larger scale products, its support organization will need to provide service and support at a high level throughout the world. If GENBAND is unable to provide the expected level of support and service to its customers, it could experience loss of customers and market share; failure to attract new customers in new markets and geographies; increased service, support and warranty costs and a diversion of development resources; and/or network performance penalties.

Regulation of the telecommunications industry could harm GENBAND's operating results and future prospects.

The telecommunications industry is highly regulated and GENBAND's business and financial condition could be adversely affected by changes in the regulations relating to the telecommunications industry. Currently, there are few laws or regulations that apply directly to access to or delivery of voice services on IP networks. GENBAND could be adversely affected by regulation of IP networks and commerce in any country where GENBAND operates, including the United States. Such regulations could include matters such as voice over the Internet or using Internet protocol, encryption technology, and access charges for service providers. The adoption of such regulations could decrease demand for GENBAND's products, and at the same time increase the cost of selling GENBAND's products, which could have a material adverse effect on GENBAND's business and consolidated financial statements.

Changes in governmental regulation, interpretation or legislative reform could increase GENBAND's costs of doing business and adversely affect its profitability.

Laws and regulations, including in the areas of advertising, consumer affairs, data protection, finance, marketing, privacy, publishing and taxation requirements, are subject to change and differing interpretations. Changes in the political climate or in existing laws or regulations, or their interpretations, or the enactment of new laws or the issuance of new regulations or changes in enforcement priorities or activity could adversely affect GENBAND's business by, among other things, increasing GENBAND's administrative, compliance and other costs; forcing GENBAND to undergo a corporate restructuring; limiting GENBAND's ability to engage in inter-company transactions with its affiliates and subsidiaries; increasing GENBAND's tax obligations, including unfavorable outcomes from audits performed by various tax authorities; affecting GENBAND's ability to continue to serve its customers and to attract new customers; affecting cash management practices and repatriation efforts; forcing GENBAND to alter or restructure its relationships with vendors and contractors; increasing compliance efforts or costs; limiting GENBAND's use of or access to personal information; restricting GENBAND's ability to market its products; and/or requiring GENBAND to implement additional or different programs and systems.

Compliance with regulations is costly and time-consuming, and GENBAND may encounter difficulties, delays or significant expenses in connection with its compliance, and GENBAND may be exposed to significant penalties, liabilities, reputational harm and loss of business in the event that it fails to comply. While it is not possible to predict when or whether fundamental policy or interpretive changes would occur, these or other changes could fundamentally change the dynamics of GENBAND's industry or the costs associated with its operations. Changes in public policy or

71

Table of Contents

enforcement priorities could materially affect GENBAND's profitability, its ability to retain or grow business, or in the event of extreme circumstances, its financial condition. There can be no assurance that legislative or regulatory change or interpretive differences will not have a material adverse effect on GENBAND's business.

GENBAND faces risks related to litigation that could result in significant legal expenses and settlement or damage awards.

GENBAND has been involved in, and may face additional, intellectual property infringement claims that could be time-consuming and costly to assert or defend, and result in GENBAND's loss of significant rights.

GENBAND has been involved in four patent infringement lawsuits involving Metaswitch Networks Ltd., Metaswitch Networks Corp. and Metaswitch Inc. (which we refer to collectively as Metaswitch), three of which are ongoing. These lawsuits have caused GENBAND to incur substantial legal costs and have been time-consuming for GENBAND's management. At this time, it is not possible to predict the outcome of the ongoing lawsuits, including whether or not any proceedings will continue, and when or how these matters will be resolved or whether GENBAND will ultimately receive, and in what sum, amounts previously awarded to it as a result of these proceedings. Regardless of whether GENBAND is ultimately successful in these lawsuits, it will likely elect to continue to incur substantial legal fees in connection with these matters. See the section entitled "GENBAND Management's Discussion and Analysis of Financial Condition and Results of Operations—Legal Costs for Patent Litigation" beginning on page 231 of this joint proxy statement/prospectus for discussion of these four lawsuits involving GENBAND and Metaswitch.

In addition, other parties may assert intellectual property infringement claims against GENBAND, and GENBAND's products may be deemed to infringe the intellectual property rights of third parties. From time to time, GENBAND receives letters alleging infringement of intellectual property rights of others. Intellectual property litigation can be expensive and time-consuming and could divert management's attention from GENBAND's business. If there is a successful claim of infringement against GENBAND, including in any of the ongoing lawsuits involving Metaswitch, GENBAND may be required to pay substantial damages to the party claiming infringement, be subjected to injunction proceedings or be required to enter into royalty or license agreements that may not be available on acceptable or desirable terms, if at all. GENBAND's failure to license the proprietary rights on a timely basis would harm its business.

GENBAND may also be subject to employment claims in connection with employee terminations. In addition, companies in GENBAND's industry whose employees accept positions with GENBAND may claim that it has engaged in unfair hiring practices. These claims may result in material litigation. GENBAND could incur substantial costs defending itself or its employees against those claims, regardless of their merits, as well as potentially be subject to injunctions that could be materially adverse to its business. Further, defending itself from those types of claims could divert GENBAND's management's attention from its operations.

If GENBAND is party to material litigation and if the defenses GENBAND claims are ultimately unsuccessful, or if GENBAND is unable to achieve a favorable settlement, GENBAND could be liable for large damage awards that could have a material adverse effect on its business and consolidated financial statements.

Current economic conditions have been and may continue to be materially adverse to GENBAND's business and results of operations.

GENBAND is unable to predict the duration of current economic conditions or their effects on its business and results of operations, but such effects have been and may continue to be materially

72

Table of Contents

adverse to GENBAND's results of operations. Economic conditions worldwide have contributed to equipment purchasing slowdowns in the telecommunications and networking industries, particularly in the wireline sector. Some of GENBAND's customers have cancelled or delayed, and may continue to cancel or delay, spending on the development or roll-out of capital and technology projects due to current economic conditions and, consequently, such have materially adversely affected GENBAND's results of operations. In addition, current economic conditions have made it increasingly difficult for GENBAND to accurately forecast future product demand, bookings and revenue.

Failure or circumvention of GENBAND's controls and procedures could impair its ability to report accurate financial results and could seriously harm its business.

Even an effective internal control system, no matter how well designed, has inherent limitations—including the possibility of the circumvention or overriding of controls—and therefore, can provide only reasonable assurance with respect to financial statement preparation. The failure or circumvention of GENBAND's controls, policies and procedures could impair GENBAND's ability to report accurate financial results and could have a material adverse effect on GENBAND's business and consolidated financial statements.

GENBAND is exposed to fluctuations in currency exchange rates that could negatively impact its financial results and cash flows.

Because a portion of GENBAND's business is conducted outside the United States, GENBAND faces exposure to adverse movements in foreign currency exchange rates. These exposures may change over time as business practices evolve, and they could have a material adverse impact on GENBAND's financial results and cash flows. An increase in the value of the dollar could increase the real cost to GENBAND's customers of its products in those markets outside the United States where GENBAND often sells in dollars, and a weakened dollar could increase the cost of local operating expenses and procurement of raw materials from sources outside the United States.

Consolidation in the telecommunications industry could harm GENBAND's business.

The telecommunications industry, including many of GENBAND's customers, has experienced consolidation, and GENBAND expects this trend to continue. Consolidation among GENBAND's customers may cause delays or reductions in capital expenditure plans and/or increased competitive pricing pressures as the number of available customers declines and the relative purchasing power of customers increases in relation to suppliers. Any of these factors could adversely affect GENBAND's business.

Man-made problems, such as computer viruses, hacking or terrorism, and natural disasters may disrupt GENBAND's operations and harm its operating results.

Despite GENBAND's implementation of network security measures, GENBAND's servers are vulnerable to computer viruses, break-ins and similar disruptions from unauthorized tampering with GENBAND's computer systems. Any attack on GENBAND's servers could have a material adverse effect on its business and consolidated financial statements. Additionally, the information systems of GENBAND's customers could be compromised due to computer viruses, break-ins and hacking, which could lead to unauthorized tampering with GENBAND's products and may result in, among other things, the disruption of its customers' business, errors or defects occurring in the software due to such unauthorized tampering, and GENBAND's products not operating as expected after such unauthorized tampering. Such consequences could affect its reputation and have a material adverse effect on its business and consolidated financial statements. Efforts to limit the ability of malicious third parties to disrupt the operations of the Internet or undermine GENBAND's own security efforts may be met with resistance. In addition, the continued threat of terrorism and heightened security and military action in

73

Table of Contents

response to this threat, or any future acts of terrorism, may cause further disruptions to the economies of the United States and other countries and create further uncertainties or otherwise materially harm GENBAND's business and consolidated financial statements. Likewise, events such as work stoppages or widespread blackouts could have similar negative impacts. Such disruptions or uncertainties could result in delays or cancellations of customer orders or the manufacture or shipment of GENBAND's products and have a material adverse effect on its business and consolidated financial statements.

GENBAND's encryption of data and other protective measures may not prevent unauthorized access to or use of sensitive data. A breach of a system may subject GENBAND to material losses or liability to its customers. A misuse of such data or a cybersecurity breach could harm GENBAND's reputation and deter customers from using GENBAND's products and services specifically, thus reducing GENBAND's revenue. In addition, any such misuse or breach could cause GENBAND to incur costs to correct the breaches or failures, expose GENBAND to uninsured liability, increase GENBAND's risk of regulatory scrutiny, subject GENBAND to lawsuits, and result in the imposition of material penalties and fines under state and federal laws or by the payment networks. While GENBAND maintains insurance coverage that may, subject to policy terms and conditions, cover certain aspects of cyber risks, GENBAND's insurance coverage may be insufficient to cover all losses.

Natural catastrophic events, such as earthquakes, fire, floods, or tornadoes, may also affect GENBAND's or its customers' operations and could have a material adverse effect on GENBAND's business.

A breach of the security of GENBAND's information systems or those of its third-party providers could adversely affect GENBAND's operating results.

GENBAND relies upon the security of its information systems and, in certain circumstances, those of its third-party providers, such as vendors, consultants and contract manufacturers, to protect its sensitive or proprietary information and information of its customers. Despite its security procedures and those of its third-party providers, GENBAND's information systems and those of its third-party providers are vulnerable to threats such as computer hacking, cyber-terrorism or other unauthorized attempts by third parties to access, modify or delete GENBAND's or its customers' sensitive or proprietary information. Such cyberattacks and other cyber incidents are occurring more frequently, are constantly evolving, are becoming more sophisticated and can take many forms. Information technology system failures, including a breach of GENBAND's or its third-party providers' data security measures through a cyberattack, other cyber incident or otherwise, or the theft or loss of laptops, other mobile devices or electronic records used to back up GENBAND's systems or its third-party providers' systems, could result in a disclosure of customer, employee, or its information or otherwise disrupt its ability to function in the normal course of business by potentially causing, among other things, delays in the fulfillment or cancellation of customer orders or disruptions in the manufacture or shipment of products or delivery of services, any of which could have a material adverse effect on GENBAND's operating results. These types of security breaches could also create exposure to lawsuits, regulatory investigations, increased legal liability and/or reputational damage. Such consequences could be exacerbated if GENBAND or its third-party providers are unable to adequately recover critical systems following a systems failure. Due to the constantly evolving nature of these security threats, the form and impact of any future incident cannot be predicted.

The loss of key personnel could disrupt and adversely affect GENBAND's business.

GENBAND's business depends upon the continued efforts, abilities and expertise of its corporate and divisional executive teams. There can be no assurance that these individuals will remain with GENBAND. GENBAND depends, to a large extent, on the abilities and participation of its current executive and management teams. GENBAND cannot provide assurance that the services of the

74

Table of Contents

members of these teams will continue to be available to it. The loss of the services of members of these teams, for any reason, may have a material adverse effect on GENBAND's business and prospects.

GENBAND may face risks associated with its international operations that could impair GENBAND's ability to grow its international revenues. If GENBAND fails to manage the operational and financial risks associated with its international operations, it could have a material adverse effect on its business and consolidated financial statements.

International operations are a significant part of GENBAND's business, and such operations will continue to require significant management attention and financial resources to successfully develop direct and indirect international sales and support channels. In addition, GENBAND's international operations are subject to other inherent risks, including reliance on channel partners; greater difficulty collecting accounts receivable and longer collection cycles; difficulties and costs of staffing and managing international operations; impacts of differing technical standards outside of the United States; compliance with international trade, customs and export control regulations; reduced protection for intellectual property rights in some countries; foreign government regulations limiting or prohibiting potential sales or increasing the cost of doing business in such markets, including reversals or delays in the opening of foreign markets to new competitors or the introduction of new technologies; challenging pricing environments in highly competitive new markets; foreign currency exchange controls, restrictions on repatriation of cash and changes in currency exchange rates; potentially adverse tax consequences; and/or political, social and economic instability, including as a result of the fragility of global financial markets, health pandemics or epidemics and/or acts of war or terrorism.

GENBAND's international revenue, both as a percentage of total revenue and absolute dollars, may vary from one period to the next, and accordingly, current data may not be indicative of future periods. If GENBAND is unable to support its business operations in international and emerging markets while balancing the higher operational and financial risks associated with these markets, its business and consolidated financial statements could be harmed.

In addition, GENBAND may not be able to develop international market demand for its products, which could impair its ability to grow its revenues. In many international markets, long-standing relationships between potential customers and their local suppliers and protective regulations, including local content requirements and approvals, create barriers to entry. GENBAND has limited experience marketing, distributing and supporting its products in certain international locations and, to do so, it expects that it will need to develop versions of its products that comply with local standards. Moreover, difficulties in foreign financial markets and economies and of foreign financial institutions, particularly in emerging markets, could adversely affect demand from customers in the affected countries.

GENBAND's business and operations in the United Kingdom are exposed to potential disruptions and uncertainty relating to Brexit.

On June 23, 2016, the U.K. voted to leave the European Union (E.U.) (referred to as Brexit), which could cause disruptions to and create uncertainty surrounding GENBAND's business and operations in the United Kingdom, including affecting relationships with existing and future customers, suppliers and employees. The effects of Brexit will depend on any agreements the U.K. makes to retain access to E.U. markets either during a transitional period or more permanently. The measures could potentially disrupt the markets GENBAND serves and the tax jurisdictions in which GENBAND operates and adversely change tax benefits or liabilities in these or other jurisdictions. In addition, Brexit could lead to legal uncertainty and potentially divergent national laws and regulations as the U.K. determines which E.U. laws to replace or replicate.

GENBAND is exposed to the credit risk of some of its customers and to credit exposures in fragile financial markets, which could result in material losses.

Due to GENBAND's reliance on significant customers, GENBAND is dependent on the continued financial strength of its customers. If one or more of its significant customers experience financial difficulties, it could result in uncollectable accounts receivable and a loss of significant customers and anticipated revenue.

Nearly all of GENBAND's sales are subject to managed credit limits, with typical payment terms of immediate to 90 days. GENBAND monitors individual customer payment capability in granting such credit limits, seeking to limit such credit to amounts GENBAND believes its customers can pay and maintain reserves it believes are adequate to cover exposure for doubtful accounts. However, there can be no assurance that GENBAND's credit customers will pay the amounts they owe to it or that the reserves GENBAND maintains will be adequate to cover such credit exposure. GENBAND's customers' failure to pay and/or its failure to maintain sufficient reserves could have a material adverse effect on GENBAND's consolidated financial statements. Additionally, in the event that turmoil in the credit markets makes it more difficult for some customers to obtain financing, those customers' ability to pay could be adversely impacted, which in turn could have a material adverse impact on GENBAND's business and consolidated financial statements.

GENBAND is subject to governmental export and import controls that could subject it to liability or impair its ability to compete in international markets.

Certain of GENBAND's products are subject to export controls and may be exported only with the required export license or through an export license exception. If GENBAND were to fail to comply with export licensing, customs regulations, economic sanctions and other laws, GENBAND could be subject to substantial civil and criminal penalties, including fines for GENBAND and incarceration for responsible employees and managers, and the possible loss of export or import privileges. In addition, if its distributors fail to obtain appropriate import, export or re-export licenses or permits, GENBAND may also be adversely affected through reputational harm and penalties. Obtaining the necessary export license for a particular sale may be time-consuming and may result in the delay or loss of sales opportunities.

Furthermore, export control laws and economic sanctions prohibit the shipment of certain products to embargoed or sanctioned countries, governments and persons. While GENBAND trains its employees to comply with these regulations, GENBAND cannot assure that a violation will not occur, whether knowingly or inadvertently. Any such shipment could have negative consequences including government investigations, penalties, fines, civil and criminal sanctions, and reputational harm. Any change in export or import regulations, economic sanctions or related legislation, shift in the enforcement or scope of existing regulations, or change in the countries, governments, persons or technologies targeted by such regulations, could result in decreased ability to export or sell GENBAND's products to existing or potential customers with international operations. Any limitation on GENBAND's ability to export or sell its products could adversely affect its business, financial condition and results of operations.

Any changes to existing accounting pronouncements or taxation rules or practices may cause adverse fluctuations in GENBAND's reported results of operations or affect how GENBAND conducts its business.

A change in accounting pronouncements or taxation rules or practices can have a significant effect on GENBAND's reported results and may affect its reporting of transactions completed before the change is effective. New accounting pronouncements, taxation rules and varying interpretations of accounting pronouncements or taxation rules have occurred in the past and may occur in the future. The change to existing rules, future changes, if any, or the need for GENBAND to modify a current

Table of Contents

tax position may adversely affect GENBAND's reported financial results or the way GENBAND conducts its business. For example, a new revenue recognition standard was issued in 2014 that will be effective for publicly registered companies in 2018, and it is possible that the adoption of this new standard may have a material impact on GENBAND's consolidated financial statements.

GENBAND's acquisitions subject it to a variety of risks that could harm its business.

GENBAND reviews and completes selective acquisition opportunities. There can be no assurances that GENBAND will be able to complete suitable acquisitions for a variety of reasons, including the identification of and competition for acquisition targets, the need for regulatory approvals, the inability of the parties to agree to the structure or purchase price of the transaction and GENBAND's inability to finance the transaction on commercially acceptable terms. In addition, any completed acquisition will subject GENBAND to a variety of other risks. In particular, GENBAND may need to allocate substantial operational, financial and management resources in integrating new businesses, technologies and products, and management may encounter difficulties in integrating the operations, personnel or systems of the acquired businesses; acquisitions may have a material adverse effect on GENBAND's business relationships with existing or future merchants or distribution partners, in particular, to the extent GENBAND consummates acquisitions that increase its sales and distribution capabilities; GENBAND may assume substantial actual or contingent liabilities, known and unknown; acquisitions may not meet GENBAND's expectations of future financial performance; GENBAND may experience delays or reductions in realizing expected synergies or benefits; GENBAND may incur substantial unanticipated costs or encounter other problems associated with acquired businesses or devote time and capital investigating a potential acquisition and not complete the transaction; GENBAND may be unable to achieve its intended objectives for the transaction; and GENBAND may not be able to retain the key personnel, customers and suppliers of the acquired business.

Additionally, GENBAND may be unable to maintain uniform standards, controls, procedures and policies as GENBAND attempts to integrate the acquired businesses, and this may lead to operational inefficiencies. These factors related to GENBAND's acquisition strategy, among others, could have a material adverse effect on its business, financial condition and results of operations.

THE SONUS SPECIAL MEETING

This section contains information about the Sonus special meeting that has been called for Sonus stockholders to consider and vote on the Sonus merger proposal, the Sonus governance-related proposals, the Sonus adjournment proposal (if it is necessary to solicit additional proxies if there are not sufficient votes to adopt the Sonus merger proposal and the Sonus governance-related proposals) and the Sonus executive compensation proposal.

This joint proxy statement/prospectus is being furnished to the stockholders of Sonus in connection with the solicitation of proxies by the Sonus board for use at the Sonus special meeting. Sonus is first mailing this joint proxy statement/prospectus and accompanying proxy card to its stockholders on or about [ ], 2017.

Date, Time and Place

A special meeting of the stockholders of Sonus will be held at the offices of Wilmer Cutler Pickering Hale and Dorr LLP, located at 60 State Street, Boston, Massachusetts 02109 on [ ], 2017, at [ ], Eastern time, unless the special meeting is adjourned.

Purpose

At the special meeting, Sonus stockholders will be asked to consider and vote upon the following matters:

•
  the Sonus merger proposal;
•
  the Sonus governance-related proposals;
•
  the Sonus adjournment proposal; and
•
  the Sonus executive compensation proposal.

Recommendation of the Sonus Board

The Sonus board has (i) approved the merger agreement and the consummation of the transactions contemplated thereby, including the Sonus merger, upon the terms and subject to the conditions set forth in the merger agreement, (ii) determined that the terms of the merger agreement and the transactions contemplated thereby, including the Sonus merger, are advisable, fair to, and in the best interests of, Sonus and its stockholders, (iii) directed that the Sonus merger and the merger agreement be submitted to Sonus stockholders for approval and adoption, (iv) recommended that Sonus stockholders approve the Sonus merger and adopt the merger agreement, and (v) declared that the merger agreement is advisable.

The Sonus board unanimously recommends that Sonus stockholders vote:

•
  "FOR" the Sonus merger proposal;
•
  "FOR" each of the Sonus governance-related proposals;
•
  "FOR" the Sonus adjournment proposal; and
•
  "FOR" the Sonus executive compensation proposal.

See the sections entitled "The Mergers—Recommendation of the Sonus Board; Sonus' Reasons for the Mergers" beginning on page 123 of this joint proxy statement/prospectus.

Sonus stockholders should carefully read this joint proxy statement/prospectus in its entirety for more detailed information concerning the merger agreement, the proposed transactions and certain compensation arrangements for Sonus' named executive officers and directors in connection with the

81

Table of Contents

mergers. In addition, Sonus stockholders are directed to the merger agreement, which is attached as Annex A to this joint proxy statement/prospectus.

Record Date; Shares Entitled to Vote

Only holders of record of shares of Sonus common stock at the close of business on the Sonus record date ([ ], 2017) will be entitled to vote shares held at that date at the Sonus special meeting or any adjournments thereof. Each outstanding share of Sonus common stock entitles its holder to cast one vote.

As of the close of business on the Sonus record date, there were [ ] shares of Sonus common stock outstanding and entitled to vote at the Sonus special meeting.

Quorum

Holders of a majority of the shares of Sonus common stock issued and outstanding and entitled to vote at the Sonus special meeting, present in person or represented by proxy, constitute a quorum. In the absence of a quorum, the chairman of the Sonus special meeting may adjourn the meeting to another place, date or time. As of the record date for the Sonus special meeting, [ ] shares of Sonus common stock will be required to achieve a quorum.

Holders of shares of Sonus common stock present at the Sonus special meeting but not voting, and shares of Sonus common stock for which Sonus has received proxies indicating that their holders have abstained, will be counted as present at the Sonus special meeting for purposes of determining whether a quorum is established.

Brokers, banks and other nominees have the discretion to vote shares held in "street name"—a term that means the shares are held in the name of the broker, bank or other nominee on behalf of its customer, the beneficial owner—on routine matters, but not on non-routine matters. Generally, broker non-votes occur when shares held by a broker, bank or other nominee for a beneficial owner are not voted with respect to a non-routine matter because the broker, bank or other nominee has not received voting instructions from the beneficial owner and the broker, bank or other nominee lacks discretionary authority to vote the shares because of the non-routine nature of the matter. Broker non-votes with respect to a matter are not counted as shares entitled to vote with respect to that matter and do not affect the voting results on that matter (unless the required vote is a percentage of all outstanding shares). Because brokers, banks and other nominees do not have discretionary voting authority with respect to any of the proposals described in this joint proxy statement/prospectus, if a beneficial owner of shares of Sonus common stock held in "street name" does not give voting instructions to the broker, bank, nominee or other holder of record, then those shares will not be voted as to any of the proposals described in this joint proxy statement/prospectus and will have the same effect as voting "AGAINST" the proposal to adopt the merger agreement and approve the Sonus merger, and will have no effect on the outcome of the vote to approve the Sonus governance-related proposals, any vote to approve the Sonus adjournment proposal or the vote to approve the Sonus executive compensation proposal. Similarly, because none of the proposals are discretionary, it is anticipated that shares held in "street name" with respect to which the beneficial owner does not provide voting instructions will not be represented at the Sonus special meeting and, accordingly, such shares will not be counted as shares present for purposes of determining the presence of a quorum. Your vote is very important, whether you hold directly or through a broker, bank or other nominee. We encourage you to read this joint proxy statement/prospectus carefully and if you are a beneficial owner, please be sure to give voting instructions to your broker, bank or other nominee.

82

Table of Contents

Vote Required

Sonus Merger Proposal

Approval of the Sonus merger proposal requires the affirmative vote of holders of a majority of the shares of Sonus common stock outstanding and entitled to vote. Accordingly, a Sonus stockholder's failure to submit a proxy card or to vote in person at the Sonus special meeting, an abstention from voting, or the failure of a Sonus stockholder who holds his or her shares in "street name" through a broker, bank or other nominee to give voting instructions to such broker, bank or other nominee, will have the same effect as voting "AGAINST" the Sonus merger proposal.

Sonus Governance-Related Proposals

Approval of each of the Sonus governance-related proposals requires the affirmative vote of holders of a majority of shares of Sonus common stock present in person or represented by proxy and entitled to vote at the Sonus special meeting on such Sonus governance-related proposal. Accordingly, abstentions with respect to any Sonus governance-related proposal will have the same effect as voting "AGAINST" such Sonus governance-related proposal, while shares not in attendance at the Sonus special meeting and broker non-votes (if any) will have no effect on the outcome of the vote on any Sonus governance-related proposal.

Sonus Adjournment Proposal

Approval of the Sonus adjournment proposal (if necessary to solicit additional proxies if there are not sufficient votes to approve the Sonus merger proposal and the Sonus governance-related proposals) requires the affirmative vote of holders of a majority of shares of Sonus common stock present in person or represented by proxy and entitled to vote at the Sonus special meeting on the Sonus adjournment proposal. Accordingly, abstentions will have the same effect as voting "AGAINST" the Sonus adjournment proposal, while shares not in attendance at the Sonus special meeting and broker non-votes (if any) will have no effect on the outcome of any vote on the Sonus adjournment proposal.

Sonus Executive Compensation Proposal

In accordance with Rule 14a-21(c) under the Exchange Act, Sonus is providing its stockholders with the opportunity to approve the Sonus executive compensation proposal. Approval of the Sonus executive compensation proposal requires the affirmative vote of holders of a majority of shares of Sonus common stock present in person or represented by proxy and entitled to vote at the Sonus special meeting on the Sonus executive compensation proposal. Accordingly, abstentions will have the same effect as voting "AGAINST" the Sonus executive compensation proposal, while shares not in attendance at the Sonus special meeting and broker non-votes (if any) will have no effect on the outcome of the vote on the Sonus executive compensation proposal.

Voting by Sonus' Directors and Executive Officers

At the close of business on the Sonus record date, the directors and executive officers of Sonus and certain of their affiliates were entitled to vote approximately [ ] shares of Sonus common stock, or [ ]% of the shares of Sonus common stock outstanding on that date. Approval of the Sonus merger proposal requires the affirmative vote of the holders of a majority of the total issued and outstanding shares of Sonus common stock on the record date. We currently expect that Sonus' directors and executive officers will vote their shares in favor of each of the proposals to be considered at the Sonus special meeting, although none of them has entered into any agreement obligating them to do so.

How to Submit Your Proxy

Whether you hold shares of Sonus common stock directly as a stockholder of record or beneficially in street name, you may submit your proxy to ensure that your shares are voted at the Sonus special meeting without attending the Sonus special meeting.

Confidential Voting

Proxy instructions, ballots and voting tabulations that identify individual Sonus stockholders are handled in a manner that protects your voting privacy. Your vote will not be disclosed either within Sonus or to third parties, except as necessary to meet applicable legal requirements, to allow for the tabulation of votes and certification of the vote and to facilitate a successful proxy solicitation. Occasionally, Sonus stockholders provide written comments on their proxy cards, which may be forwarded to Sonus management and the Sonus board.

Solicitation of Proxies

Sonus will pay the costs of soliciting proxies from Sonus stockholders. Sonus has also engaged Innisfree M&A Incorporated to solicit proxies for the Sonus special meeting from Sonus stockholders, brokers, banks, nominees and other institutions for a fee of approximately $25,000, plus reasonable out-of-pocket expenses.

Sonus will also request brokerage houses, custodians, nominees and fiduciaries to forward copies of the proxy materials to those persons for whom they hold shares and request instructions for voting the proxies. Sonus will reimburse such brokerage houses and other persons for their reasonable expenses in connection with forwarding proxy and solicitation materials to the beneficial owners of Sonus common stock and in obtaining voting instructions from such beneficial owners.

SONUS PROPOSALS

Sonus Merger Proposal

Pursuant to Section 251 of the DGCL, Sonus is submitting the Sonus merger and the merger agreement to its stockholders at the Sonus special meeting, at which the Sonus merger and the merger agreement will be considered and a vote taken on a proposal for their approval and adoption.

For a summary of the Sonus merger, the merger agreement and the business combination, including the background of the mergers, Sonus' reasons for the transactions, the opinions of Sonus' financial advisor and related matters, see the sections entitled "The Mergers" and "The Merger Agreement" beginning on pages 106 and 190, respectively, of this joint proxy statement/prospectus.

THE SONUS BOARD UNANIMOUSLY RECOMMENDS THAT SONUS STOCKHOLDERS VOTE "FOR" THE SONUS MERGER PROPOSAL.

Sonus Governance-Related Proposals

Sonus is asking its stockholders to approve the following proposals relating to certain governance and other provisions in the New Solstice charter that will be applicable to New Solstice stockholders upon consummation of the mergers and that give effect to the stockholders agreement. In the merger agreement, Sonus and GENBAND agreed that New Solstice and Sonus, as the sole stockholder of New Solstice prior to the Sonus merger, will take all requisite action to cause the proposed form of New Solstice charter and the proposed form of amended and restated bylaws of New Solstice to be effective prior to the Sonus merger. The New Solstice charter will differ in material respects from Sonus' charter, as described in the following Sonus governance-related proposals.

Each of the five Sonus governance-related proposals is cross-conditioned upon the approval by Sonus stockholders of the Sonus merger proposal and each other Sonus governance-related proposal, and completion of the mergers is cross-conditioned on the approval by Sonus stockholders of each of the Sonus governance-related proposals. None of the actions contemplated by the Sonus governance-related proposals will proceed if the Sonus merger proposal or any of the Sonus governance-related proposals is not approved by Sonus stockholders. As a result, a vote against any of the Sonus governance-related proposals effectively will be a vote against adoption of the merger agreement and the transactions contemplated by the merger agreement. If the Sonus merger proposal is approved, failure to gain stockholder approval for any of the Sonus governance-related proposals could cause the mergers not to close or to close later than expected, and/or could cause Sonus to incur substantial costs and expenses. If the mergers are completed, the provisions of the New Solstice charter and New Solstice's amended and restated bylaws, including the terms of the shares of New Solstice common stock, will become applicable to Sonus stockholders who continue as New Solstice stockholders as a result of the mergers regardless of whether they vote in favor of the Sonus merger or any of the Sonus governance-related proposals.

The form of the New Solstice charter and the form of stockholders agreement are attached to this joint proxy statement/prospectus as Annexes F and I, respectively, and Sonus encourages its stockholders to read the following proposals together with Annexes F and I. The provisions to which these proposals relate are summarized under "Description of New Solstice Capital Stock," "Comparison of Stockholder Rights" and "Other Related Agreements—Principal Stockholders Agreement" in this joint proxy statement/prospectus.

Proposal A: Provisions Related to the Amount and Classes of Authorized Stock

Under the New Solstice charter, New Solstice will have authority to issue 240,000,000 shares of common stock and 10,000,000 shares of preferred stock, which is a larger number of authorized shares than authorized under Sonus' current charter. Under Sonus' charter, Sonus is authorized to issue 120,000,000 shares of common stock and 5,000,000 shares of preferred stock.

86

Table of Contents

The increased amount of authorized shares of New Solstice common stock will provide greater flexibility in the capital structure of the combined company following the mergers by allowing it to raise capital that may be necessary to further develop its business, to fund potential acquisitions, to have shares available for use in connection with stock plans and to pursue other corporate purposes that may be identified by the New Solstice board of directors in the future. The increased amount of authorized shares of New Solstice preferred stock will give the New Solstice board of directors the same power granted to the Sonus board in its parallel blank check preferred stock provision, but with respect to a larger number of shares. Consistent with the authority of the Sonus board of directors under Sonus' charter, the New Solstice board of directors will have broad power to establish the rights and preferences of any shares of preferred stock that New Solstice may issue in the future.

THE SONUS BOARD UNANIMOUSLY RECOMMENDS THAT SONUS STOCKHOLDERS VOTE "FOR" THIS SONUS GOVERNANCE-RELATED PROPOSAL.

Proposal B: Provisions Related to Board Size and Composition

Under the New Solstice charter, the size of the New Solstice board of directors must be established by the New Solstice board in accordance with the requirements of the stockholders agreement, which in turn will require that the size of the New Solstice board of directors be set at nine so long as the OEP Stockholders continue to own at least 10% of the shares of New Solstice common stock issued to them pursuant to the mergers. In addition, the stockholders agreement will give OEP Stockholders the following rights to designate New Solstice directors:

•
  for so long as the OEP Stockholders beneficially own at least 80% of the shares of New Solstice common stock beneficially owned in the aggregate on the date of the stockholders agreement, the OEP Stockholders will have the right to nominate five New Solstice board members, of which at least two must be independent directors;
•
  from and after the first time that the OEP Stockholders beneficially own less than 80% of the shares of New Solstice common stock beneficially owned in the aggregate on the date of the stockholders agreement, the number of directors that the OEP Stockholders will have the right to nominate will be reduced to four New Solstice board members, of which at least one must be an independent director;
•
  from and after the first time that the OEP Stockholders beneficially own less than 70% of the shares of New Solstice common stock beneficially owned in the aggregate on the date of the stockholders agreement, the number of directors that the OEP Stockholders will have the right to nominate will be reduced to three New Solstice board members, of which at least one must be an independent director;
•
  from and after the first time that the OEP Stockholders beneficially own less than 50% of the shares of New Solstice common stock beneficially owned in the aggregate on the date of the stockholders agreement, the number of directors that the OEP Stockholders will have the right to nominate will be reduced to two New Solstice board members, neither of whom need be an independent director;
•
  from and after the first time that the OEP Stockholders beneficially own less than 30% of the shares of New Solstice common stock beneficially owned in the aggregate on the date of the stockholders agreement, the number of directors that the OEP Stockholders will have the right to nominate will be reduced to one New Solstice board member, who does not need to be an independent director; and
•
  upon the first date that the OEP Stockholders beneficially own less than 10% of the shares of New Solstice common stock they beneficially owned as of the date of the stockholders agreement, the OEP Stockholders will have no board designation rights and New Solstice may require any designees of the OEP Stockholders to resign from the New Solstice board.

87

Proposal E: Provisions Relating to Section 203 of the DGCL

Pursuant to the New Solstice charter, New Solstice will expressly elect not to be governed by the provisions of Section 203 of the DGCL. Instead, the New Solstice charter will provide that, notwithstanding any other provisions of the DGCL or the New Solstice charter, New Solstice shall not engage in any business combination with any interested stockholder for a period of three years following the time that such stockholder became an interested stockholder unless: (i) the New Solstice board has approved, before the acquisition time, either the business combination or the transaction that resulted in the person becoming an interested stockholder, (ii) upon consummation of the transaction that resulted in the person becoming an interested stockholder, the person owns at least 85% of the corporation's voting stock (excluding shares owned by directors who are officers and shares owned by employee stock plans in which participants do not have the right to determine confidentially whether shares will be tendered in a tender or exchange offer) or (iii) at or after the person or entity becomes an interested stockholder, the business combination is approved by two-thirds of the total number of authorized directors, whether or not there exist any vacancies in previously authorized directorships, and by a majority of the independent directors (as defined in the stockholders agreement).

The foregoing restriction will not apply if (i) a stockholder becomes an interested stockholder inadvertently and (a) as soon as practicable divests itself of ownership of sufficient shares so that the stockholder ceases to be an interested stockholder; and (b) would not, at any time within the three-year period immediately prior to a business combination between New Solstice and such stockholder, have been an interested stockholder but for the inadvertent acquisition of ownership; or (ii) the business combination is proposed prior to the consummation or abandonment of and subsequent to the earlier of the public announcement or the notice of a proposed transaction which (a) constitutes one of the transactions described in clause (A), (B) or (C) below; (b) is with or by a person who either was not an interested stockholder during the previous three years or who became an interested stockholder with the approval of the New Solstice board; and (c) is approved or not opposed by a majority of the New Solstice board then in office (but not less than one) who were directors prior to any person becoming an interested stockholder during the previous three years or were recommended for election or elected to succeed such directors by a majority of such directors.

The proposed transactions referred to in the preceding paragraph are limited to (A) a merger or consolidation of New Solstice (except for a merger in respect of which, pursuant to Section 251(f) of the DGCL, no vote of the stockholders is required); (B) a sale, lease, exchange, mortgage, pledge, transfer or other disposition (in one transaction or a series of transactions), whether as part of a dissolution or otherwise, of assets of New Solstice or of any of its direct or indirect majority-owned subsidiaries (other than to any direct or indirect wholly owned subsidiary or to New Solstice) having an aggregate market value equal to 50% or more of either that aggregate market value of all of the assets of New Solstice determined on a consolidated basis or the aggregate market value of all the outstanding stock of New Solstice; or (C) a proposed tender or exchange offer for 50% or more of the outstanding voting stock of New Solstice. New Solstice will give not less than 20 days' notice to all interested stockholders prior to the consummation of any of the transactions described in clause (A) or (B) above.

Sonus has not opted out of the protections of Section 203 of the DGCL. As a result, the statute applies to Sonus.

Sonus Adjournment Proposal

This proposal would permit Sonus, if necessary, to adjourn the Sonus special meeting to solicit additional proxies if there are insufficient votes to approve the Sonus merger proposal and the Sonus governance-related proposals.

If the time and place of an adjourned meeting (and means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such adjourned meeting) are announced at the meeting at which the adjournment is taken, no notice of an adjourned meeting need be given unless the adjournment is for more than 30 days or if, after the adjournment, a new record date is fixed for the adjourned meeting, in which case notice of the adjourned meeting will be given to Sonus stockholders of record entitled to vote at the adjourned meeting. At any adjourned meeting, any business may be transacted that might have been transacted if the meeting had been held as originally called.

Sonus Executive Compensation Proposal

Pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and Rule 14a-21(c) of the Exchange Act, Sonus is seeking non-binding, advisory stockholder approval of the compensation of Sonus' named executive officers that is based on or otherwise relates to the mergers. This proposal, commonly known as "say-on-golden parachute," gives Sonus stockholders the opportunity to vote on a non-binding, advisory basis on the "golden parachute" compensation payments that will or may be paid to the named executive officers of Sonus in connection with the mergers.

The golden parachute compensation that Sonus' named executive officers may be entitled to receive in connection with the mergers is summarized under the sections entitled "The Mergers—Interests of Directors and Executive Officers in the Transactions—Interests of Directors and Executive Officers of Sonus in the Transactions—Stock Options and Other Stock-Based Awards" and "—Severance Arrangements with Sonus Named Executive Officers" beginning on pages 172 and 173, respectively, of this joint proxy statement/prospectus and is quantified under the section entitled "The Mergers—Interests of Directors and Executive Officers in the Transactions—Interests of Directors and Executive Officers of Sonus in the Transactions—Quantification of Potential Payments to Sonus Named Executive Officers in Connection with the Mergers" beginning on page 174 of this joint proxy statement/prospectus.

Those summaries include all compensation and benefits that will or may be paid to Sonus' named executive officers in connection with the mergers.

Accordingly, Sonus is requesting that stockholders adopt the following resolution, on a non-binding, advisory basis:

"RESOLVED, that the stockholders of Sonus Networks, Inc. approve, on an advisory basis, the compensation to be paid to its named executive officers that is based on or otherwise relates to the mergers as disclosed pursuant to Item 402(t) of Regulation S-K in the Golden Parachute Compensation table and the related narrative disclosures."

THE SONUS BOARD UNANIMOUSLY RECOMMENDS THAT SONUS STOCKHOLDERS VOTE "FOR" THE SONUS EXECUTIVE COMPENSATION PROPOSAL.

Other Matters to Come Before the Sonus Special Meeting

No other matters are intended to be brought before the Sonus special meeting by Sonus, and Sonus does not know of any matters to be brought before the Sonus special meeting by others. If, however, any other matters properly come before the Sonus special meeting, the persons named in the proxy will vote the shares represented thereby in accordance with their judgment on any such matter.

Record Date; Shares Entitled to Vote

Only holders of record of shares of GB common stock at the close of business on the GB record date ( [ ], 2017) will be entitled to vote shares held at that date at the GB special meeting or any adjournments thereof. Each outstanding share of GB common stock entitles its holder to cast one vote.

As of the close of business on the GB record date, there were [ ] shares of GB common stock, par value $0.001 per share, outstanding and entitled to vote at the GB special meeting.

Quorum

Holders of a majority in voting power of GB common stock entitled to vote at the GB special meeting, present in person or represented by proxy, constitute a quorum. In the absence of a quorum, the chairman of the GB special meeting may adjourn the meeting to another place, date or time. As of the record date for the GB special meeting, [ ] shares of GB common stock will be required to achieve a quorum.

Holders of GB common stock present at the GB special meeting but not voting, and shares of GB common stock for which GB has received proxies indicating that their holders have abstained, will be counted as present at the GB special meeting for purposes of determining whether a quorum is established.

Vote Required

Proposal to Approve the GB Merger and Adopt the Merger Agreement by GB Stockholders. Approving the GB merger and adopting the merger agreement requires the affirmative vote of holders of a majority of the shares of GB common stock outstanding and entitled to vote. If any shares of GB common stock were not affirmatively voted in favor of the adoption of the merger agreement and the approval of the GB merger for any reason, it would have the same effect as a vote "AGAINST" approval of the merger proposal.

Proposal to Adjourn the GB Special Meeting. Approving the proposal to adjourn the GB special meeting (if necessary to solicit additional proxies if there are not sufficient votes to approve the GB merger and adopt the merger agreement) requires the affirmative vote of holders of a majority in voting power of the shares of GB common stock present in person, or represented by proxy, and entitled to vote on the adjournment proposal. Accordingly, abstentions will have the same effect as a vote "AGAINST" the proposal to adjourn the GB special meeting, while shares not in attendance at the GB special meeting and broker non-votes (if any) will have no effect on the outcome of any vote to adjourn the GB special meeting.

Notwithstanding the foregoing, in accordance with the GENBAND Stockholders Agreement, OEP has the right to cause stockholders of GB holding a majority of shares to vote in favor of approval of the GB merger and adoption of the merger agreement. If OEP exercises this right, then such vote would be the only vote required to approve the GB merger and adopt the merger agreement.

The merger agreement, among other things, contemplates four separate mergers: the Sonus merger, the GENBAND merger, the GB merger and the GB II merger, each of which is discussed below. The mergers will result in Sonus' business and GENBAND's business being held under New Solstice. Former Sonus stockholders will own approximately 50%, and former GENBAND party shareholders will own approximately 50%, of the shares of New Solstice common stock issued and outstanding immediately following the consummation of the mergers.

Solstice Merger Sub will merge with and into Sonus, at which time the separate corporate existence of Solstice Merger Sub will cease, and Sonus will survive the merger as a wholly owned subsidiary of New Solstice.

The GENBAND Merger

Cayman Merger Sub will merge with and into GENBAND, at which time the separate existence of Cayman Merger Sub will cease, and GENBAND will survive the merger as a wholly owned subsidiary of New Solstice.

The GB Merger

Consideration to be Received in Connection with the Transactions Contemplated by the Merger Agreement

Sonus Merger

At the effective time of the Sonus merger, each share of common stock of Sonus that is owned by Sonus immediately prior to the effective time will automatically be cancelled and extinguished and will cease to exist, and no consideration will be paid for such shares. Each other share of Sonus common stock issued and outstanding immediately prior to the effective time will be converted into the right to receive one share of New Solstice common stock. Each share of common stock of Solstice Merger Sub issued and outstanding immediately prior to the effective time will be converted into one share of common stock of Sonus (as the surviving entity of the Sonus merger).

GENBAND Merger

At the effective time of the GENBAND merger, each share of capital stock or other equity interests of GENBAND owned by GENBAND will automatically be cancelled and extinguished and will cease to exist, and no consideration will be paid for such shares. Each share of capital stock or other equity interests of GENBAND owned by GB or GB II as of immediately prior to the effective time of the GENBAND merger will be converted into one share of GENBAND (as the surviving entity of the GENBAND merger). Each share of capital stock or other equity interests of GENBAND other than those described above will be converted into the right to receive a portion of a share of New Solstice common stock and such share's portion of the promissory note issued by New Solstice to shareholders of GENBAND that the holder of such GENBAND share is entitled to receive upon a Realization Event as defined in the GENBAND Articles of Association assuming that the total Realization Consideration as defined in the GENBAND Articles of Association is equal to the value of the total number of Sonus common stock outstanding immediately prior to the GENBAND merger plus the aggregate value of the promissory note to be issued by New Solstice, and all such shares of capital stock or other equity interests of GENBAND will cease to be outstanding and will automatically be cancelled and extinguished and will cease to exist. For additional details of the promissory note, see the section entitled "Other Related Agreements—The Promissory Note" beginning on page 217 of this joint proxy statement/prospectus.

All outstanding limited liability company interests of Cayman Merger Sub will be converted into one share of GENBAND (as the surviving entity of the GENBAND merger).

GB Merger

At the effective time of the GB merger, each share of GB common stock owned by GB will automatically be cancelled and extinguished and will cease to exist and no consideration will be paid for such shares. Each other share of GB common stock will be converted into the right to receive a share of New Solstice common stock multiplied by an exchange ratio equal to (a) the total number of shares of New Solstice common stock that GB would be entitled to receive upon a Realization Event as defined in the GENBAND Articles of Association assuming the total Realization Consideration as defined in the GENBAND Articles of Association is equal to the value of total number of shares of Sonus common stock outstanding immediately prior to the GB merger, divided by (b) the total number of shares of GB common stock outstanding immediately prior to the effective time of the GB merger (other than the shares of GB common stock that will be cancelled as described above). In exchange for such shares of New Solstice common stock (if any), each share of GB common stock will automatically be cancelled and extinguished and will cease to exist. Each limited liability company interest of GB Merger Sub will remain unchanged and will continue to remain outstanding as a limited liability company interest in the GB entity surviving the GB merger.

Table of Contents

GB II Merger

At the effective time of the GB II merger, each share of GB II common stock owned by GB II will automatically be cancelled and extinguished and will cease to exist and no consideration will be paid for such shares. Each other share of GB II common stock will be converted into the right to receive a share of New Solstice common stock multiplied by an exchange ratio equal to (a) the total number of shares of New Solstice common stock that GB II would be entitled to receive upon a Realization Event as defined in the GENBAND Articles of Association assuming the total Realization Consideration as defined in the GENBAND Articles of Association is equal to the value of the total number of shares of Sonus common stock outstanding immediately prior to the GB II merger, divided by (b) the total number of shares of GB II common stock outstanding immediately prior to the effective time of the GB II merger (other than the shares of GB II common stock that will be cancelled as described above). In exchange for such shares of New Solstice common stock (if any), each share of GB II common stock will automatically be cancelled and extinguished and will cease to exist. Each limited liability company interest of GB Merger Sub will remain unchanged and will continue to remain outstanding as a limited liability company interest in the GB entity surviving the GB II merger.

GENBAND Party Mergers

Pursuant to Article 5.2 of the GENBAND Articles of Association attached as Annex C to this joint proxy statement/prospectus, all dividends and distributions (including upon a Realization Event, as described below) shall be made in accordance with the waterfall which sets out the priority of distribution amongst the holders of the different classes of shares, and giving effect to all benchmark amounts under the GENBAND Articles of Association. The merger consideration amount to be received by the holders of each class of shares in GENBAND, GB and GB II will therefore be dependent on the value of the total merger consideration. Below is a summary of the approximate thresholds at which holders of each class of shares will participate in the distribution of the merger consideration.

Summary Table of Waterfall Thresholds by Class of Shares (as of July 31, 2017)

Class of Shares |  | Threshold Amount
--- | --- | ---
C |  | $1
E* |  | $478 million
A** |  | $618 million
B** |  | $1.612 billion

*
  Approximately 42,165,041 of Class E Shares will not participate in the distribution of the merger consideration until a threshold of approximately $484 million is met.
**
  The threshold at which the Class A Shares and Class B Shares will participate will continue to increase until closing due to the Class C accretion, which is approximately $6 million per month.

For the purposes of the GENBAND Articles of Association, a "Realization Event" includes, among other things, a merger or consolidation in which GENBAND is a constituent party, if following such merger or consolidation, holders of the shares of GENBAND immediately prior to such merger or consolidation do not hold at least 50.1% of the voting power of GENBAND or an entity holding 100% of the voting power of GENBAND after such a merger or consolidation.

Under the merger agreement, GENBAND shareholders (other than GB and GB II) will also have the right to receive a three-year promissory note issued by New Solstice as described in the section entitled "The Mergers—Consideration to be Received in Connection with the Transactions

108

Table of Contents

Contemplated by the Merger Agreement—GENBAND Merger" beginning on page 107 of this joint proxy statement/prospectus. Consideration from the promissory note will be distributed to GENBAND shareholders (other than GB and GB II) in accordance with the waterfall. Pursuant to the terms of the merger agreement, GB and GB II stockholders are not entitled to receive any consideration under the promissory note.

Background of the Mergers

The network communications marketplace in which Sonus and GENBAND compete has come under significantly increasing competitive pressures as a result of several factors, including rapid technological changes, significant consolidation among the major customers for network communications products and the existence of multiple vendors in the marketplace, including Sonus and GENBAND.

In response to these competitive pressures, and as part of its ongoing oversight of Sonus' business and affairs, the Sonus board periodically reviews Sonus' condition (financial and otherwise), challenges and prospects with a view toward maximizing stockholder value. In addition, the Sonus board has considered numerous potential strategic alternatives for Sonus, including potential business combinations and strategic acquisitions as a means to create and maximize value for Sonus stockholders. These alternatives have involved GENBAND and other third parties.

The GENBAND and GB boards of directors (which we refer to as the GENBAND and GB boards) and management, in their ongoing effort to maximize shareholder value, have also periodically reviewed and assessed GENBAND's business strategy, the various trends and conditions affecting the network communications market, GENBAND's businesses generally and a variety of strategic alternatives reasonably available to GENBAND, including a potential business combination. As part of this process, the GENBAND and GB boards and management have occasionally reached out to third parties regarding potential strategic transactions, including Sonus.

In July 2010, Charlie Vogt, GENBAND's then Chief Executive Officer, approached Sonus about the potential for a business combination resulting in GENBAND and Sonus entering into a mutual confidentiality agreement in order to share certain non-public information about their respective businesses. Subsequently, there were no material discussions between Sonus and GENBAND regarding a potential business combination until September 2012.

In September 2012, at an investor conference in New York, David Walsh, the current GENBAND Chief Executive Officer and Chairman of its board, who at that time was GENBAND's Chairman of its board and a partner of OEP, and another representative of OEP approached Raymond P. Dolan, Sonus' President and Chief Executive Officer and a member of the Sonus board, and discussed with Mr. Dolan the benefits of a potential business combination.

In November 2012, Sonus and GENBAND renewed their prior mutual confidentiality agreement and Mr. Vogt, Daryl Raiford, GENBAND's Chief Financial Officer, and various members of GENBAND's senior management team met with representatives of Sonus to propose and discuss a potential business combination.

In late November 2012, GENBAND made a non-binding proposal for a business combination in which Sonus would be valued at $450 million and GENBAND at $520 million, with $150 million being paid to Sonus stockholders in the form of cash dividend and $220 million used by GENBAND to retire existing debt, through the use of cash on hand, and a new $100 million debt facility, after which there would be equal equity ownership in a combined publicly traded entity for Sonus stockholders and GENBAND shareholders. In January 2013, Messrs. Walsh and Raiford along with James Koven, a partner of OEP, met with Mr. Dolan and other senior representatives of Sonus to further discuss

109

Table of Contents

GENBAND's proposal. Subsequently, the Sonus board determined not to pursue this proposal, and no further substantive discussions took place at that time.

On March 24, 2015, Sonus issued a press release prior to market open announcing lower than anticipated revenues for the first quarter of 2015 and the year as a whole, and the Sonus common stock opened trading at $8.80 per share, down from a closing price of $13.16 per share the prior trading day. A few days after that time, Mr. Walsh, who had become GENBAND's Chief Executive Officer and Chairman of its board, telephoned Mr. Dolan to discuss a potential business combination.

On March 30, 2015, Mr. Walsh provided to Mr. Dolan a non-binding proposal for a business combination between Sonus and GENBAND in which the equity ownership in a combined publicly traded entity would be 34% for Sonus stockholders and 66% for GENBAND shareholders. Later that day, members of the Sonus and GENBAND senior management teams met to discuss GENBAND's growth strategies and a potential business combination.

On April 1, 2015, the Sonus board held a telephonic meeting in which representatives from WilmerHale, Sonus' outside counsel, provided an overview of the Sonus board's fiduciary duties and the GENBAND proposal was discussed. The Sonus board authorized management to continue discussions with GENBAND.

On April 3, 2015, Mr. Dolan and Mr. Walsh discussed the most recent proposal, including the proposed equity split between Sonus stockholders and GENBAND shareholders.

On April 8, 2015, Sonus and GENBAND amended their mutual confidentiality agreement to extend it for another two years.

On April 9, 2015, Mr. Dolan, Mark Greenquist, Sonus' then Chief Financial Officer, and other members of Sonus' senior management, along with representatives of Evercore, Sonus' financial advisor, met in New York with Mr. Walsh, Mr. Raiford, and other senior management of GENBAND and representatives of Guggenheim Securities, GENBAND's financial advisor. The participants discussed a potential business combination, including the likely structure and the mutual benefits for each party. Thereafter, Mr. Walsh proposed that the post-combination equity ownership be 40% for Sonus stockholders and 60% for GENBAND shareholders.

The Sonus board held a telephonic meeting on April 15, 2015 to discuss, among other items, an update on Sonus' discussions with GENBAND and authorized continued discussions with GENBAND. The Sonus board also approved the retention of Evercore as Sonus' financial advisor with respect to a possible business combination with GENBAND and with respect to the examination of potential alternatives, including remaining as a standalone publicly traded company.

On April 23, April 24 and April 27, 2015, Mr. Greenquist, Mr. Raiford and other representatives of Sonus and GENBAND senior management and representatives of Evercore and Guggenheim Securities met in New York to discuss potential synergies and mutual benefits that could be realized from a business combination.

On May 4, 2015, Mr. Greenquist, Mr. Raiford and other representatives of Sonus and GENBAND, representatives of WilmerHale and of Latham & Watkins LLP, outside counsel to GENBAND (which we refer to as Latham & Watkins), discussed by telephone potential tax and structure issues relating to a business combination. Also on that day, senior management of Sonus and GENBAND met in New York to discuss projected revenues for each company.

The Sonus board held a telephonic meeting on May 6, 2015, in which representatives of Evercore and WilmerHale participated. The representatives of Evercore reviewed Sonus' recent financial results, the proposal by GENBAND, and various alternatives including the potential combination with GENBAND, sale to or combination with other entities, acquisitions of other entities by Sonus, and continued operation as an independent entity. The Sonus board authorized continued discussions with

GENBAND, including negotiation of the principal economic terms of a proposed business combination. On the same day, senior management of Sonus and GENBAND met at Sonus' headquarters to review the companies' respective technologies and possible synergies that might be realized in a business combination.

On May 11, 2015, Mr. Greenquist, Mr. Raiford and other senior management of Sonus and GENBAND, along with representatives of Evercore and Guggenheim Securities, met in New York to discuss projected revenues for each entity and revised forecasts presented by GENBAND, as well as potential synergies that might be achieved in a business combination.

On May 12 and May 20, 2015, senior management of Sonus and GENBAND, along with representatives of Evercore and Guggenheim Securities, met in New York to discuss the relative valuations of Sonus and GENBAND. Following such meetings, representatives of Evercore proposed to representatives of Guggenheim Securities that Sonus stockholders hold 60% and GENBAND shareholders hold 40% of the combined publicly traded entity.

On May 21, 2015, GENBAND submitted a revised proposal for a business combination in which Sonus stockholders would receive 44% and GENBAND shareholders would receive 56% of a combined publicly traded entity. The proposal also offered Sonus stockholders an option to elect to receive up to $124 million in cash, at $10.00 per share, in lieu of equity of the combined entity. If the cash election was fully subscribed, Sonus stockholders would own 37.1% and GENBAND shareholders would own 62.9% of the combined publicly traded entity. The proposal also indicated that the GENBAND shareholders would agree not to transfer shares received in the transaction for 180 days and would consider customary and reasonable limits on OEP exercising control as a significant stockholder of the combined entity, including standstill provisions, limitations on certain transfers and supermajority approval requirements for certain business combinations. The proposal also indicated a willingness to have an independent board with two OEP designees.

The Sonus board held a telephonic meeting on May 26, 2015, in which representatives of Evercore and WilmerHale participated. The Sonus board discussed GENBAND's most recent proposal and potential alternatives. Representatives of Evercore reviewed valuation implications of GENBAND's proposal and preliminary valuation analyses for Sonus on a standalone basis. Representatives of WilmerHale reviewed various governance provisions that the Sonus board might wish to consider proposing in a business combination with GENBAND in which OEP would be a significant stockholder of a combined entity, including with respect to board composition, standstill provisions, supermajority voting requirements for business combinations and transfer restrictions. The Sonus board authorized continued discussions with GENBAND, including negotiation of the principal economic terms of a proposed business combination, and determined not to affirmatively seek other sale or business combination alternatives, given that it had not determined to proceed with any transaction and the competitive risks identified that could result from such a process, until it had determined that an acceptable economic and governance framework for a potential combination had been reached with GENBAND.

On May 27, 2015, representatives of Evercore communicated to representatives of Guggenheim Securities a counteroffer that included, among other things, a post-closing equity split of 56% for Sonus stockholders and 44% for GENBAND shareholders.

On May 28, 2015, a Sonus director met with Mr. Walsh and a member of GENBAND's management team in New York to discuss GENBAND's technology and rationale for a business combination.

On June 9, 2015, GENBAND sent a revised proposal to Sonus reflecting an equal equity ownership split between Sonus stockholders and GENBAND shareholders, with a similar cash election option for Sonus stockholders for up to $124 million at $10.00 per share, subject to proration, to be supported by fully-committed debt financing. If the cash election was fully subscribed, the post-combination equity ownership would have been 42.85% for Sonus' stockholders and 57.15% for GENBAND shareholders. This proposal also referenced customary registration rights for GENBAND shareholders and transfer restrictions imposed on GENBAND shareholders for 180 days. Governance terms included an equal number of initial directors being nominated by Sonus and GENBAND and OEP thereafter having the right to designate 50% of the directors of the combined publicly traded entity.

On June 10 and 11, 2015, the Sonus board held regularly scheduled meetings in Boston, at which representatives from Evercore and WilmerHale were present. The Sonus board discussed GENBAND's latest proposal and representatives of Evercore reviewed valuation implications of the revised proposal. Representatives of WilmerHale outlined the fiduciary duties of the Sonus directors and reviewed potential governance provisions, including as to board size and composition, as well as standstill provisions, transfer restrictions and supermajority voting requirements for business combinations applicable to OEP as a significant stockholder of the combined entity. The Sonus board determined that the proposed 50/50 equity split was acceptable subject to reaching suitable agreement on governance provisions, but determined that the cash election and resultant leveraging, and increased control by OEP, of the combined entity would not be advisable. Accordingly, the Sonus board authorized a counterproposal to GENBAND for a proposed business combination with a 50/50 equity split but no cash election. This proposal included a proposed governance framework in which Sonus would have the right to designate a majority of the board of directors of the combined entity, including the Chief Executive Officer of the combined entity.

On June 11, 2015, representatives of Evercore informed representatives of Guggenheim Securities by telephone that the Sonus board did not support the cash election feature, provided an outline of the governance framework approved by the Sonus board and discussed the framework.

On June 12, 2015, Mr. Dolan and Mr. Walsh discussed management of the combined entity and representatives of Evercore and Guggenheim Securities further discussed governance matters.

On June 16, 2015, Sonus received a revised proposal on governance from GENBAND. The material differences related to the size of the board, the number of directors OEP would be entitled to nominate, the qualification standards for a director to be considered an independent director under the governance framework, the composition of board committees, the scope of standstill and transfer restrictions applicable to OEP and supermajority voting requirements for business requirements. Through July 15, 2015, representatives of Sonus, GENBAND, Evercore, Guggenheim Securities, OEP, WilmerHale and Latham & Watkins negotiated the material terms of a governance framework.

On June 18 and June 19, 2015, Messrs. Dolan, Lynch and Walsh, as well as representatives of OEP, met at various times in New York and discussed the management structure of the combined entity, including the selection of the Chief Executive Officer and, because the Chief Executive Officer was expected to be a director, how that choice might affect the director designation rights OEP would receive in a transaction.

On June 25, 2015, the Sonus board held a telephonic meeting in which representatives of Evercore and WilmerHale participated. The Sonus board discussed the current status of negotiations regarding the governance framework and management structure. The Sonus board authorized continued discussions with GENBAND.

On June 26, 2015, Messrs. Dolan and Walsh met in New York to discuss a potential management structure for the combined entity, including the possibility of Mr. Walsh serving as Chief Executive

112

Table of Contents

Officer of the combined entity and Mr. Dolan serving as Executive Chairman of the combined entity's board of directors, comprised of 11 directors. Messrs. Dolan and Walsh also discussed the possibility that, of the 11 directors, five would be nominees of OEP, two of whom would be independent and one of whom would be Mr. Walsh, and the remaining six would be Mr. Dolan and five other Sonus nominees.

On July 8, 2015, the Sonus board held a telephonic meeting in which representatives of Evercore and WilmerHale participated. The Sonus board discussed the current status of negotiations regarding the governance framework and authorized continued discussions with GENBAND.

On July 16, 2015, representatives of Sonus and GENBAND reached tentative agreement on a governance framework providing for 12 directors, with six initially designated by GENBAND, including one who would be designated as the initial Chief Executive Officer (subject to reasonable approval by a majority of the entire board) and two who would be independent under applicable stock exchange and SEC rules and not otherwise a current or former OEP director, officer, employee or consultant, and six initially designated by Sonus, including one who would be designated as Executive Chairman and five others who would be independent under applicable stock exchange and SEC rules. Thereafter, OEP would have the right to nominate five directors, including two independent directors, with such nomination rights decreasing to zero as its holdings in the combined entity received in the transaction decreased, and to propose any replacement for the Chief Executive Officer so long as OEP was entitled to nominate five directors. In addition, OEP nominees would be entitled to participate on all board committees (subject to applicable stock exchange and SEC rules) and would constitute a percentage of each committee proportional to the number of OEP designees as compared to the entire board (less the Chief Executive Officer), rounded up to the nearest whole person, except rounded down to the nearest whole person for the nominating and corporate governance committee, which would have the right to nominate all directors other than those nominated by OEP. In addition, OEP would be subject to standstill limitations and restrictions on voting, transfers and change in control transactions, and receive registration and preemptive rights, substantially similar to those in the stockholders agreement.

On July 20, 2015, the GENBAND and GB boards held a telephonic meeting in which representatives of Guggenheim Securities and Latham & Watkins participated. The GENBAND and GB boards, together with their advisors, discussed the chronology of discussions and negotiations between GENBAND and Sonus and the economic terms of the proposed transaction. Representatives of Latham & Watkins reviewed and discussed with the GENBAND and GB boards the proposed governance framework, including board size and composition, committee structure, voting requirements, transfer restrictions and the standstill provisions. The GENBAND and GB boards discussed the due diligence process and directed the GENBAND advisors and management to continue negotiations with Sonus. The GENBAND and GB boards also determined to establish a special transaction advisory committee comprised of the independent directors, John Bayless, Mark Lancaster, Steven D. Levy and Ray Rothrock, to analyze the proposed transaction, to represent the interests of the non-OEP shareholders and to make a recommendation to the GENBAND and GB boards regarding the proposed transaction, including the value to be attributed to GENBAND in a merger pursuant to the GENBAND Articles of Association.

On July 20, 2015, the Sonus board held a telephonic meeting in which representatives of Evercore and WilmerHale participated. The Sonus board reviewed the economic and governance provisions that had been negotiated and authorized the commencement of legal and confirmatory business diligence and the negotiation of definitive documentation relating to a business combination with GENBAND. The Sonus board also authorized Evercore to contact 16 potential strategic buyers that management and Evercore had identified as likely to have the greatest strategic interest in a transaction with Sonus.

Thereafter through mid-November 2015, representatives of Sonus and GENBAND undertook legal and further business diligence on each other, which efforts took place at in-person meetings, telephone conferences and through review of materials posted in electronic data rooms.

On July 31, 2015, the Chief Financial Officer of one of the parties contacted by representatives of Evercore (which we refer to as Company A) telephoned Mr. Greenquist to discuss a possible transaction. No specific terms were discussed.

On August 5, 2015, the GENBAND and GB boards held a telephonic meeting in which representatives of Guggenheim Securities and Latham & Watkins participated. The GENBAND and GB boards and their advisors discussed the current status of the due diligence process, including business and legal due diligence.

On August 6, 2015, Sonus sent GENBAND initial drafts of merger and contribution agreements to accomplish the business combination. On August 8, 2015, GENBAND sent Sonus an initial draft of a stockholders agreement reflecting the governance framework. Thereafter, representatives of WilmerHale and Latham & Watkins exchanged drafts of a registration rights agreement and a voting agreement, and negotiated the terms of those agreements. The material issues included the scope of the representations and warranties the GENBAND shareholders would make and remedies available to Sonus upon a breach, the ability of Sonus to respond to unsolicited proposals and to terminate the merger agreement to accept a superior proposal, the size of the termination fee payable by Sonus and the circumstances in which it would be payable, and whether Sonus would adopt certain provisions in its charter in lieu of being governed by DGCL Section 203.

In light of the management structure then under consideration with Mr. Walsh as Chief Executive Officer of the combined publicly traded entity, it was determined that several Sonus directors who had not already met with Mr. Walsh would meet with him. Such meetings took place on August 19, August 27 and September 16, 2015.

On August 18 and August 25, 2015, Mr. Dolan and the Chief Executive Officer of Company A discussed a potential transaction by telephone. No specific terms were discussed. On September 3, 2015, senior management of Sonus met with members of Company A's management at Company A's headquarters. No confidentiality agreement was executed, no specific terms were discussed and no consensus to continue discussions was reached.

On August 21, 2015, the GENBAND and GB boards held a telephonic meeting in which its financial and legal advisors participated. Representatives of Guggenheim Securities discussed with the GENBAND and GB boards the financial metrics of each of GENBAND and Sonus and the potential synergy forecast for the proposed business combination. The GENBAND and GB boards also discussed the current state of the proposed merger agreement and related transaction agreements, open issues relating thereto and the status of due diligence.

On September 8, 2015, the Sonus board held a telephonic meeting. The Sonus board discussed the status of due diligence efforts and negotiations on the documentation related to the proposed business combination with GENBAND, and the Sonus directors who recently met with Mr. Walsh reported on their meetings with him.

The Sonus board met on September 16, 2015, with representatives of Evercore and WilmerHale in attendance. The Sonus board discussed the current status of negotiations and the remaining open issues in the various proposed agreements with GENBAND, as well as the status of the due diligence efforts. Sonus directors who met with Mr. Walsh for the first time earlier that day reported on their meeting with him. Representatives of Evercore noted that only one party contacted following the July 20, 2015 board meeting, Company A, had expressed any interest in exploring a transaction and no confidentiality agreements had been requested or executed. Management reported that based on its interactions with Company A, including most recently at the meeting with Company A two weeks earlier following which

114

Table of Contents

no further discussions or information had been requested, further interest by Company A did not appear likely based on Company A's lack of interest to date. Representatives of Evercore reviewed the current forecasts for Sonus and GENBAND, including the associated risks of achieving these forecasts, compared current forecasts to prior forecasts, and reviewed updated synergy estimates, valuation analyses of Sonus and GENBAND on a standalone basis, the relative values of each and the expected contributions of each to a combined entity. The Sonus board authorized continued discussions with GENBAND and continued due diligence.

Between September 17, 2015 and November 13, 2015, Messrs. Dolan, Greenquist, Walsh and Raiford and senior management at Sonus and GENBAND, as well as representatives of Evercore, Guggenheim Securities and OEP, held several meetings and telephone conferences in which the financial results and forecasts of Sonus and GENBAND, including the risks of achieving these forecasts, as well as expected synergies and other potential benefits of a business combination, were discussed.

On November 12, 2015, the Sonus board held a telephonic meeting in which Mr. Dolan reported to the Sonus board on Sonus' discussions with GENBAND since the prior Sonus board meeting. At that meeting, Mr. Dolan recommended that the Sonus board terminate discussions related to a business combination with GENBAND because the parties were unable to agree on relative valuations that would support a 50/50 equity split between the GENBAND shareholders and Sonus stockholders in light of risks facing each company at that time, including market risks associated with the then current customer demand for certain of the types of network communications products that each company sold and product and market development risks associated with new growth strategies that had been identified by each company. The Board accepted Mr. Dolan's recommendation and instructed Sonus management to terminate discussions with GENBAND relating to a possible business combination.

On November 13, 2015, Messrs. Dolan and Walsh spoke by telephone and Mr. Dolan stated that Sonus had determined to terminate discussions relating to a business combination, which determination was confirmed by Sonus in writing on November 16, 2015.

On March 7, 2016, Mr. Greenquist and Mr. Raiford met in New York to discuss recent financial and business results and to assess whether the companies should consider resuming discussions regarding a potential business combination in light of the passage of time and the possibility that the uncertainty caused by the risks facing each company in November 2015 had diminished. No substantive terms were discussed and following such meeting both parties determined that any further discussions should take place only after each party had better visibility into revenue for the second half of 2016.

On September 6, 2016, Messrs. Walsh, Raiford, Dolan and Greenquist and other senior management of Sonus and GENBAND met in New York to discuss the financial results and prospects for each company, and on the following day, Mr. Dolan met with representatives of OEP, including Mr. Koven, to discuss the possibility of again exploring a business combination. No substantive terms were discussed.

At a telephonic meeting held on September 14, 2016, the Sonus board approved resuming initial discussions with GENBAND concerning a possible business combination. The Sonus board determined to resume discussions with GENBAND regarding a potential business combination in light of the Sonus board's belief that remaining a stand-alone public company would present significant risks to Sonus and its stockholders, particularly in light of the challenging carrier spending environment, declining valuation multiples among both communications equipment and next generation networking peers and Sonus' lack of scale.

On October 5, 2016, Messrs. Dolan and Lynch met in New York with GENBAND's lead independent director, Mr. Levy, and Mr. Koven, who continued throughout the negotiations between GENBAND and Sonus to be a principal representative of OEP, to discuss governance and

115

Table of Contents

management structure, and agreed to continue discussions in December 2016 after Sonus' regularly scheduled December board meeting so Sonus could focus on the integration of a recently acquired business.

The Sonus board held a meeting on December 9, 2016, which representatives of Evercore and WilmerHale attended. Representatives of Evercore reviewed Sonus' recent financial results and stock price trading history, current projections in comparison to prior projections both for Sonus and for capital expenditure in the network communications market, preliminary valuation analyses for Sonus and strategic alternatives, including standalone operation, potential acquisitions, a business combination with GENBAND or other market participants or a sale of Sonus. The Sonus board discussed the various alternatives and concluded that Sonus should seek significant growth in an effort to improve profitability and be viewed more favorably by customers and that a business combination with GENBAND, particularly in light of each party's continued progress in implementing its growth strategies since the parties terminated discussions in November 2015, likely presented the best alternative for doing so. The Sonus board authorized continued discussions with GENBAND regarding a business combination.

On December 20, 2016, Sonus and GENBAND entered into a new mutual confidentiality agreement, including a standstill provision. In late 2016, GENBAND began discussions with a strategic third party regarding a potential combination transaction. GENBAND and this third party signed a non-disclosure agreement, shared initial diligence and entered into a preliminary term sheet. After some exchange of preliminary due diligence information, these discussions failed to progress. GENBAND and the strategic third party terminated negotiations in February 2017.

On January 5 and 6, 2017, Messrs. Dolan, Walsh and Raiford and other senior management of Sonus and GENBAND along with representatives of Evercore and OEP met in New York to explore a potential business combination. The participants discussed financial results and forecasts and due diligence items.

On January 12, 2017, the Sonus board held a telephonic meeting in which representatives of Evercore and WilmerHale participated. Representatives of Evercore reviewed preliminary financial analyses of Sonus and GENBAND on a standalone and combined basis, as well as a preliminary contribution analysis and preliminary synergy assumptions that were subject to due diligence and validation. Representatives of WilmerHale reviewed the fiduciary duties of the Sonus directors. The Sonus board discussed potential strategic and financial benefits of a business combination with GENBAND, including that the increased scale and diversification resulting from the proposed transaction would give the combined company greater flexibility to pursue acquisitions and other strategic transactions. Thereafter, the Sonus board authorized Mr. Lynch to negotiate with representatives of OEP regarding governance provisions applicable to OEP as a significant stockholder similar to those previously under negotiation in the prior discussions, and authorized management to evaluate potential synergies based on current operations and with assistance from Evercore negotiate relative valuations of Sonus and GENBAND.

On January 23, 2017, members of management from Sonus, including Mr. Dolan, and GENBAND, including Mr. Walsh, and representatives of OEP met to review GENBAND's technologies. A similar meeting with Mr. Lynch and another Sonus director in attendance was held the next day.

On January 25, 2017, representatives of Evercore and OEP discussed valuation of the proposed combined company. Representatives of Evercore presented information supporting their position that Sonus' stockholders should receive 60% of the combined entity.

On February 2 and 3, 2017, Mr. Dolan, Mr. Walsh and representatives of Evercore and OEP had meetings and calls to discuss relative valuations, in which representatives of OEP presented information supporting their position that GENBAND shareholders should receive 60% of the combined entity.

On February 6, 2017, the Sonus board held a telephonic meeting in which representatives of Evercore and WilmerHale participated. Management and representatives of Evercore reported on discussions relating to relative valuations. Representatives of Evercore reviewed GENBAND's forecasts and updated synergy estimates, as well as potential valuation implications for Sonus stockholders of a combination reflecting the various equity splits proposed by each side. The Sonus board authorized continued discussions with GENBAND regarding relative valuations of GENBAND and Sonus. After this meeting, representatives of Evercore met with representatives of OEP to discuss relative valuations.

On February 8, 2017, representatives of OEP proposed two alternatives for relative valuations of Sonus and GENBAND. One was an equal split of equity but with the combined entity issuing a note for $50 million to GENBAND shareholders and assuming, as part of GENBAND's outstanding liabilities, approximately $10 million in transaction expenses, in addition to accrued management fees payable by GENBAND to OEP, to be paid upon closing. The other was a post-combination equity split of 48% for Sonus stockholders and 52% for GENBAND shareholders, with the same assumption of GENBAND liabilities but without Sonus issuing a note.

On February 9, 2017, the Sonus board held a telephonic meeting in which representatives of Evercore and WilmerHale participated. Representatives of Evercore reviewed the recent proposals from OEP and the prospective financial impacts of those proposals to Sonus stockholders, as well as a preliminary valuation of Sonus on a standalone basis. The Sonus directors discussed potential governance and management structures for a combined entity and whether Evercore should be asked to again contact other potentially interested parties to examine possible alternatives to a business combination with GENBAND. The Sonus board authorized continued discussions with GENBAND but deferred making any decision about contacting third parties at that time.

On February 13, 2017, representatives of WilmerHale began negotiations with representatives of Latham & Watkins over governance provisions, including the size of the board, the selection of initial nominees, the number of director designees thereafter accorded to OEP and the composition of board committees, as well as over issues on the merger and related agreements that remained open when prior negotiations had terminated in November 2015. Negotiations continued through May 22, 2017.

On February 15, 2017, Messrs. Dolan and Lynch, representatives of Evercore and representatives of OEP met in New York and discussed relative valuations and the management structure for a combined entity. Representatives of Evercore proposed a transaction in which Sonus stockholders and GENBAND shareholders would each receive 50% of the equity of a combined entity, without the note or liability assumption reflected in OEP's prior proposal.

On February 16, 2017, the Sonus board held a telephonic meeting in which representatives of Evercore, WilmerHale and Richards, Layton & Finger, P.A., Delaware counsel to Sonus (which we refer to as Richards, Layton & Finger), participated. The Sonus board discussed the status of negotiations with GENBAND. Representatives of Richards, Layton & Finger outlined the fiduciary duties of the Sonus directors in connection with the consideration of the proposed business combination with GENBAND. Management and representatives of Evercore reviewed the results of the outreach efforts in July and August 2015, the likelihood that those or other parties might have an interest in exploring an acquisition of or business combination with Sonus at this time, and potential competitive risks associated with contacting third parties to explore an acquisition of or business combination with Sonus. The Sonus board determined that, in light of the likely value presented by an acquisition or other business combination at that time, especially given the then current price of Sonus common stock, the lack of response from prior attempts to solicit interest and the market for network communication products in general, a business combination with GENBAND was viewed as the best reasonably available means to maximize value to Sonus stockholders, negotiations with GENBAND should continue and no outreach should be made to other parties.

Table of Contents

On February 23, 2017, representatives of OEP proposed a 50/50 equity split of the combined entity among Sonus stockholders and GENBAND shareholders, with the combined entity issuing a note for $25 million to the GENBAND shareholders, or a 48% interest to Sonus stockholders and a 52% interest to GENBAND shareholders with no note. This proposal also permitted Sonus to terminate the merger agreement to accept a superior proposal without having to first hold a stockholder vote to consider approval of the merger agreement but provided OEP the right to make market purchases of the combined entity's common stock, up to a 60% aggregate interest.

Between February 26, 2017 and April 19, 2017, Mr. Lynch had discussions with representatives of OEP about the governance provisions and management structure of a combined entity. The material governance issues discussed included the size of the combined company's board, the selection of initial director nominees, the number of director designees thereafter accorded to OEP, the composition of board committees and who would serve as the initial chairman and the initial chief executive officer of the combined company.

On April 21, 2017, representatives of WilmerHale and Latham & Watkins began exchanging drafts of the merger agreement, stockholders agreement, registration rights agreement and voting agreement and continued negotiating such agreements through May 22, 2017. The material issues negotiated were the definition of independent director, the structures of the board committees of the combined entity, the size of the termination fee payable by Sonus and the circumstances in which the fee would be payable, and the ability of OEP to acquire shares of the combined entity in the market following the business combination.

On May 2, 2017, senior management of Sonus and GENBAND, as well as representatives of Evercore and OEP, met in New York to commence the final confirmatory due diligence process.

On May 4, 2017, the independent directors of the GENBAND board (Messrs. Bayless, Lancaster, Levy and Rothrock) (which we refer to as the GENBAND Advisory Committee) held a telephonic meeting after being informed by members of the GENBAND board that the GENBAND Advisory Committee would be re-established, in which representatives of Baker Botts L.L.P. (which we refer as Baker Botts) participated. The meeting was convened in order to consider and approve various initial matters, including the retention of legal and financial advisors. The GENBAND Advisory Committee retained Baker Botts as independent legal counsel and resolved to again utilize the services of Guggenheim Securities in connection with their committee responsibilities. The GENBAND Advisory Committee also appointed Mr. Levy to serve as its chairman.

At this meeting, the GENBAND and GB boards attended to regular business matters and also discussed various aspects of the proposed transaction with Sonus, including the potential synergies between GENBAND and Sonus, Sonus' financial performance and the process and timing to get to a potential signing of the merger agreement. Representatives of Latham & Watkins reviewed with the GENBAND and GB boards the current drafts of the transaction agreements, including the merger agreement, the stockholders agreement, the voting agreement and the registration rights agreement. The GENBAND and GB boards further determined that Guggenheim Securities should be re-engaged to provide financial advisory services to GENBAND and update their financial analysis performed in 2015. The GENBAND board also determined that the GENBAND Advisory Committee should be established and authorized to make a recommendation to the GENBAND board regarding the value of the consideration to be received by GENBAND shareholders in the proposed transaction as contemplated by the GENBAND Articles of Association, and further approved and ratified the actions taken by the GENBAND Advisory Committee at its meeting on May 4, 2017.

On May 11, 2017, the Sonus board held a telephonic meeting in which representatives of Evercore and WilmerHale participated. The Sonus board discussed the open issues in the definitive agreements, as well as the size and terms of the note to be issued by the combined entity as additional consideration for the GENBAND shareholders and the existing GENBAND liabilities (including accrued management fees owed to OEP and other transaction expenses). Management then reviewed a five-year operating plan that had been circulated in advance of the meeting, including the underlying assumptions, noting that while it was not customary for Sonus to prepare such plans, Evercore required a five-year plan to complete its financial analyses. The Sonus board approved the five-year operating plan and authorized that it be provided to GENBAND and used by Evercore in its financial analyses of the business combination.

On May 17, 2017, the Sonus board held a telephonic meeting in which representatives of Evercore and WilmerHale participated. Senior management reviewed the current status of negotiations and remaining issues on the definitive documentation. Representatives of Evercore reviewed the structure and expected financial terms of the proposed business combination, sources and uses of funds and the pro forma capitalization of the combined entity, key governance terms, Evercore's process for evaluating the financial terms of the transaction and preliminary financial analyses of Sonus and GENBAND, and of the combined entity, in light of historical and projected financial results for each company and anticipated cost synergies developed by management. Senior management reviewed the anticipated cost synergies and the process to develop such estimates, as well as adjustments that management had made to GENBAND financial projections provided by GENBAND management, including the basis for making such adjustments. The Sonus board discussed the expected synergies as well as the proposed adjustments to the GENBAND projections and determined both to be reasonable and appropriate for Evercore to use in its financial analyses.

On May 17 and 18, 2017, representatives of Evercore and OEP finalized the terms of the note to be issued by the combined entity to GENBAND shareholders, decreasing the face value to $22.5 million, providing for an annual interest rate of 7.5% for the first six months and 10% thereafter, as well as agreeing that the accrued management fees payable to OEP would not exceed $10 million. Representatives of Latham & Watkins and WilmerHale finalized the terms of all the transaction documents, including the form of note.

On May 19, 2017, the GENBAND and GB boards held a telephonic meeting in which representatives of Latham & Watkins participated. At this meeting, the GENBAND and GB boards discussed the terms of the proposed transaction with Sonus, including the proposed 50/50 equity split between the parties, the use of a volume weighted average price (or VWAP) or similar mechanic for determining the market value of the merger consideration to be determined pursuant to the GENBAND Articles of Association shortly before the closing of the mergers, the note, and the payment of accrued management fees owed to OEP and transaction expenses, including the payment of the fee to Guggenheim Securities. The Latham & Watkins representatives observed that the use of a VWAP or similar mechanic is common in merger and acquisition transactions where one of the parties involved has publicly traded securities. In addition, the GENBAND and GB boards discussed the treatment of unvested Sonus equity awards, which would survive the proposed mergers.

On May 22, 2017, the GENBAND Advisory Committee held a telephonic meeting in which representatives of Guggenheim Securities and Baker Botts participated. Representatives of Guggenheim Securities discussed the proposed provisions of the merger agreement requiring the value of the merger consideration to be determined by the GENBAND board using a VWAP of Sonus common stock shortly before closing. The Guggenheim Securities representatives noted that it would be unusual for the valuation in a transaction involving a publicly traded company such as Sonus to be determined using metrics other than the market price of the publicly traded security. The Guggenheim Securities representatives suggested that using a VWAP determined on a trading window consisting of as few days as possible prior to closing would be an appropriate time period that would be indicative of the value of the merger consideration. In particular, the GENBAND Advisory Committee and the Guggenheim Securities representatives discussed shortening the VWAP trading window in the draft merger agreement, and the advantages and disadvantages thereof. The GENBAND Advisory Committee also inquired about the fairness opinion of Guggenheim Securities to be delivered to the GENBAND board prior to the execution of the merger agreement, as well as the potential for delivery of valuation materials to the GENBAND Advisory Committee regarding the merger consideration shortly prior to closing. The members of the GENBAND Advisory Committee made inquiries of Guggenheim Securities regarding the potential benefit of investor disclosures following the public announcement of the transaction. Following the departure of the Guggenheim Securities representatives from the meeting, the GENBAND Advisory Committee discussed the advantages and disadvantages of using

120

Table of Contents

VWAP in determining the value of the merger consideration, as well as the appropriate time window thereof. The GENBAND Advisory Committee unanimously approved making a recommendation to the GENBAND board of a 5-day VWAP to determine the value of the merger consideration for purposes of the GENBAND Articles of Association, coupled with a recommendation that the GENBAND board direct management to conduct a robust investor relations campaign with respect to the transaction to highlight the financial merits of the business combination. Immediately following the meeting, Mr. Levy relayed such recommendations to the GENBAND board.

On May 22, 2017, the GENBAND and GB boards held a telephonic meeting to consider approval of the proposed merger agreement. At this meeting:

•
  representatives of Latham & Watkins reviewed with the GENBAND and GB boards their fiduciary duties when considering the proposed transaction and the requirements of the GENBAND Articles of Association;
•
  Messrs. Walsh and Raiford and representatives of Latham & Watkins reviewed with the GENBAND and GB boards the outcome of the negotiations with Sonus and the terms and conditions of the proposed merger agreement and related transaction documents;
•
  the GENBAND board considered and approved the recommendation of the GENBAND Advisory Committee to utilize a 5-day VWAP to determine merger consideration and require an investor relations campaign with respect to the transaction; and
•
  representatives of Guggenheim Securities reviewed with the GENBAND and GB boards Guggenheim Securities' financial analysis of the merger consideration to be received by the GENBAND shareholders, GB stockholders and GB II stockholders, and rendered an oral opinion, confirmed by delivery of a written opinion dated May 23, 2017, to the GENBAND and GB boards to the effect that, as of that date and based on and subject to the matters considered, the procedures followed, the assumptions made and various limitations of and qualifications to the review undertaken, taking into account the Sonus merger, the merger consideration to be received by the GENBAND shareholders, GB stockholders and GB II stockholders was fair, from a financial point of view, to the GENBAND shareholders, GB stockholders and GB II stockholders, as a whole. See the section entitled "—Opinion of GENBAND's Financial Advisor" beginning on page 153 of this joint proxy statement/prospectus.

The GENBAND and GB boards considered various reasons to approve the merger agreement (see the section entitled "—Reasons of GENBAND, GB and GB II for the Transactions" beginning on page 167 of this joint proxy statement/prospectus), including certain countervailing factors. After discussions with its financial and legal advisors and Messrs. Walsh and Raiford, and in light of the reasons considered, the GENBAND and GB boards (i) approved the merger agreement and the consummation of the transactions contemplated thereby, including the GENBAND merger and the GB merger, upon the terms and subject to the conditions set forth in the merger agreement, (ii) determined that the terms of the merger agreement and the transactions contemplated thereby, including the GENBAND and GB mergers, are advisable and in the best interests of, GENBAND shareholders and GB stockholders, respectively, (iii) directed that the GENBAND merger and GB merger and the merger agreement be submitted to GENBAND shareholders and GB stockholders, respectively, for approval, (iv) recommended that GENBAND shareholders and GB stockholders approve the GENBAND merger and GB merger, respectively, and the merger agreement, and (v) declared that the merger agreement is advisable.

On May 22, 2017, the board of directors of GB II, which was comprised entirely of officers of GENBAND, also approved the merger agreement and the consummation of the transactions contemplated thereby upon the terms and subject to the conditions set forth in the merger agreement, determined that the terms of the GB II merger and the other transactions contemplated by the merger

agreement are advisable and in the best interests of GB II and its stockholders, directed that the GB II merger and the merger agreement be submitted to its stockholders for approval and recommended that such stockholders approve the GB II merger and adopt the merger agreement.

On May 22, 2017, the Sonus board held two telephonic meetings in which representatives of Evercore and WilmerHale participated. Members of senior management reported on the final resolution of the terms of the transactions and of issues in the definitive documentation. Representatives of WilmerHale reviewed the terms of the merger agreement, stockholders agreement, registration rights agreement and voting agreement, and advised the Sonus directors of their fiduciary duties regarding their consideration and approval of the transaction. Representatives of Evercore reviewed the terms of the transaction, various trading multiples implied for Sonus and GENBAND based on such terms, the sources and uses of funds in the transaction and the pro forma capitalization of the combined entity, as well as various financial analyses it had performed as to the standalone valuation of both Sonus and GENBAND, including discounted cash flow, peer trading multiple, precedent transaction multiple and present value of future share price analyses. Representatives of Evercore also referred to certain pro forma combination analyses and certain historical trading prices and research analyst price targets for the Sonus common stock that Evercore provided as additional reference points for the directors to consider. Representatives of Evercore then rendered to the Sonus board its oral opinion, subsequently confirmed by delivery of its written opinion, dated May 22, 2017, that, as of the date of its opinion and based upon and subject to the procedures followed, matters considered, assumptions and qualifications set forth in its opinion, that the Sonus exchange ratio is fair, from a financial point of view, to the holders of the Sonus common stock and the GENBAND total consideration, taking into account a significant portion of the GENBAND total consideration is in the form of the combined entity's common stock, is fair, from a financial point of view, to Sonus. After discussing the final terms of the merger agreement, stockholders agreement and related agreements, as well as the terms of the proposed transaction with GENBAND, the Sonus board unanimously approved the merger agreement, stockholders agreement and related agreements, and recommended that Sonus stockholders vote to adopt the merger agreement. In addition, the Sonus board resolved to amend the By-laws of Sonus to add an exclusive forum provision.

On May 23, 2017, Sonus, the GENBAND parties and the other parties to the merger agreement executed the merger agreement. On the same day, before the opening of trading on NASDAQ, Sonus and GENBAND issued a joint press release announcing the execution of the merger agreement.

On June 20, 2017, Sonus management furnished to Evercore revised estimates of the net operating losses of Sonus and the GENBAND parties, together with corresponding revisions to the applicable tax rate estimates (which we refer to collectively as the Management Revised Tax Rate and NOL Estimates). As they relate to Sonus, the Management Revised Tax Rate and NOL Estimates included updated NOL carryover estimates as of March 31, 2017, a revised schedule of projected NOLs usage based on updated assumptions around transfer pricing, and current NOLs expiration schedule and revised standalone tax rates used in the Discounted Cash Flow Analyses. As they relate to the GENBAND parties, the Management Revised Tax Rate and NOL Estimates excluded the impact of NOLs and standalone revised tax rates used in undertaking the Discounted Cash Flow Analyses. Sonus requested that Evercore evaluate, as of May 22, 2017 and taking into account the Management Revised Tax Rate and NOL Estimates, the fairness of the Sonus exchange ratio, from a financial point of view, to the holders of Sonus common stock and the fairness of the GENBAND total consideration, taking into account a significant portion of such GENBAND total consideration is in the form of New Solstice common stock, from a financial point of view, to Sonus.

On June 22, 2017, at a telephonic meeting of the Sonus board in which representatives of Evercore and representatives of WilmerHale participated, representatives of Evercore reviewed with the Sonus board Evercore's updated analyses and the differences between the updated analyses and the analyses that were presented to the Sonus board at the May 22, 2017 Sonus board meeting. Representatives of

122

Table of Contents

Evercore rendered an oral opinion, subsequently confirmed by delivery of a written opinion (which we refer to as the Second Evercore Opinion) that, based upon and subject to the factors, procedures, assumptions, qualifications and limitations set forth in its opinion, as of May 22, 2017 and taking into account the Management Revised Tax Rate and NOL Estimates, the Sonus exchange ratio was fair, from a financial point of view, to the holders of Sonus common stock and the GENBAND total consideration, taking into account a significant portion of such GENBAND total consideration is in the form of New Solstice common stock, was fair, from a financial point of view, to Sonus.

Following receipt of the Second Evercore Opinion, the Sonus board reaffirmed its recommendation that the Sonus stockholders approve the Sonus merger and adopt the merger agreement.

Recommendation of the Sonus Board; Sonus' Reasons for the Mergers

At a meeting held on May 22, 2017, the Sonus board unanimously (i) determined that the merger agreement and the transactions contemplated thereby, including without limitation the mergers, are advisable, fair to and in the best interests of Sonus and the Sonus stockholders, (ii) adopted and approved the merger agreement and the transactions contemplated thereby, and (iii) directed that the merger agreement be submitted to Sonus stockholders for their adoption and recommended that the Sonus stockholders adopt the merger agreement in accordance with applicable law.

In the course of reaching its recommendation, the Sonus board consulted with Sonus' senior management and financial advisor, Evercore, outside legal counsel, WilmerHale, and Delaware counsel, Richards, Layton & Finger, and considered a number of factors, both positive and negative, and potential benefits and detriments of the mergers to Sonus and its stockholders. The Sonus board also considered strategic alternatives reasonably available to Sonus, including remaining a stand-alone public company or pursuing a strategic transaction with another third party. For the reasons described below, including the risks of remaining a standalone public company and the lack of significant interest of other third parties in pursuing a strategic transaction with Sonus, the Sonus board determined that the proposed transaction with GENBAND is the best reasonably available alternative for Sonus.

The decision of the Sonus board to enter into the merger agreement was the result of careful consideration by the Sonus board of numerous factors weighing positively in favor of the merger, including the following material factors:

•
  the Sonus board's belief, based on prior experience at Sonus and in the telecommunications industry generally, that remaining a standalone company would present significant risks for Sonus because:
  •
    the significant consolidation among customers of Sonus in the telecommunications industry has left Sonus with fewer customers and facing increased competition;
  •
    in light of this customer consolidation, the telecommunications carrier spending environment remains depressed; and
  •
    Sonus lacks the size and scale necessary to compete effectively with its larger, better capitalized competitors;
•
  the Sonus board's belief that GENBAND has made significant progress in implementing its growth strategies since the parties terminated discussions regarding a potential business combination in November 2015, including the progress made in product and market development efforts for GENBAND's next generation communications platform as a service (CPaaS) products branded under Kandy. The Sonus board believed that this progress significantly reduced the risks associated with GENBAND's business, as compared to the risks associated with GENBAND's future business in November 2015;

123

Table of Contents

•
  the Sonus board's belief that, in light of this progress, a combination with GENBAND would allow Sonus to benefit from deeper and broader account coverage, product diversification, significant economies of scale and cost savings and significantly improved profitability and cash flows, which the Sonus board believes will facilitate investment in existing growth initiatives and new technologies and drive greater revenues in the future;
•
  the strategic review undertaken by the Sonus board and management and their view of the challenges facing participants in the telecommunications industry, including increasing competition, declining valuation multiples among communications equipment and next generation peers, potential consolidation of other industry participants and the impact of such factors on the strategic alternatives reasonably available to Sonus if it did not pursue the mergers;
•
  the synergies and other benefits to the combined company that could result from the mergers, including an enhanced competitive and financial position, increased scale and the potential to realize, according to Sonus management, an estimated $57 million in run-rate cost synergies by 2020, which are summarized in further detail under the heading "The Mergers—Certain Prospective Financial Information of Sonus and GENBAND—Estimated Cost Synergies" and which the Sonus board believed exceed any cost-reduction benefits that reasonably could be achieved by Sonus on a stand-alone basis because Sonus' publicly announced cost-reduction initiatives had improved Sonus' cost structure significantly, thereby making achievement of further stand-alone cost-reduction benefits unlikely;
•
  the fact that, during and following the bidder outreach conducted by Evercore following the July 20, 2015 meeting of the Sonus board, no third party other than GENBAND expressed significant interest in pursuing a strategic transaction with Sonus;
•
  the Sonus board's understanding of the respective businesses, operations, financial condition, earnings, strategy and prospects of Sonus and GENBAND, including the report of Sonus' management and Sonus' advisors on the results of their due diligence review of GENBAND and its assets, liabilities, earnings and financial condition, as well as Sonus' and GENBAND's historical and projected financial performance;
•
  the fact that, since the consideration to be received by Sonus stockholders in connection with the Sonus merger will consist of shares of New Solstice common stock, Sonus stockholders will own approximately 50% of the combined company and have the opportunity to participate in the future earnings and expected growth of the combined company and any future appreciation in the value of the combined company's common stock should they decide to retain the shares of New Solstice common stock payable in connection with the Sonus merger;
•
  the price negotiations that occurred between the parties resulting in Sonus stockholders owning approximately 50% of the combined company;
•
  the opinion of Evercore rendered to the Sonus board on May 22, 2017, which was subsequently confirmed by delivery of a written opinion dated such date, and, at the request of management of Sonus, rendered to the Sonus board on June 22, 2017, and subsequently confirmed by delivery of a written opinion dated such date, to the effect that, as of such date and based upon and subject to the various assumptions made, procedures followed, matters considered, and qualifications and limitations set forth in Evercore's written opinions, the Sonus exchange ratio was fair from a financial point of view to Sonus stockholders and the GENBAND total consideration was fair, from a financial point of view, to Sonus, as more fully described in the section entitled "—Opinion of Sonus' Financial Advisor" of this joint proxy statement/prospectus;

124

Table of Contents

•
  the fact that, apart from the promissory note, the combined company is not expected to incur any indebtedness in connection with the mergers;
•
  the post-closing governance structure of the combined company under the terms of the merger agreement (see the section entitled "Management and Other Information of the Combined Company") and the stockholders agreement (see the section entitled "Other Related Agreements—Principal Stockholders Agreement"), including that:
  •
    the combined company's board of directors initially will consist of nine directors;
  •
    Richard J. Lynch, the current Chairman of the Sonus board, will be the Chairman of the combined company's board of directors;
  •
    Raymond P. Dolan, the current Chief Executive Officer of Sonus and a member of the Sonus board, will be the Chief Executive Officer of the combined company and a member of the combined company's board of directors;
  •
    Sonus will have the right to designate two other directors who qualify as independent for purposes of applicable SEC and stock exchange rules;
  •
    two of the five directors of the combined company who will be designated by GENBAND under the merger agreement must be independent for purposes of applicable SEC and stock exchange rules, as well as the stockholders agreement;
  •
    following the completion of the mergers, the number of directors whom the OEP Stockholders will have the right to designate to serve on the combined company's board of directors will decrease as the OEP Stockholders dispose of the shares of New Solstice common stock that they initially acquire in connection with the mergers and a sufficient number of these nominees must be independent to ensure that a majority of the combined company's directors are independent;
  •
    the rights of the OEP Stockholders to designate directors of the combined company are not transferrable;
  •
    the nominating and corporate governance committee of the combined company's board of directors will consist of three directors (i) who will be selected by a majority of the independent directors serving on the combined company's board of directors, and (ii) at least two of whom will not be designates of the OEP Stockholders;
  •
    the nominating and corporate governance committee of the combined company's board of directors will determine the size and membership of the audit committee, the compensation committee and any committee formed to consider a transaction between the combined company and an OEP Stockholder or any of its affiliates; and
  •
    transactions between an OEP Stockholder or any of its affiliates must be approved by a majority of the independent directors of the combined company;
•
  the obligations of the OEP Stockholders under the stockholders agreement, including their voting obligations and standstill and transfer restrictions, as more particularly described under the section entitled "Other Related Agreements—Principal Stockholders Agreement";
•
  the Sonus board's view that while the merger agreement contains a covenant prohibiting Sonus from soliciting third party acquisition proposals, it permits the Sonus board to change or withdraw its recommendation in favor of the merger agreement in connection with a superior proposal or an intervening event (as defined under the heading "The Merger Agreement—No Solicitation—No Solicitation by Sonus" beginning on page 201 of this joint proxy statement/prospectus), or to discuss, negotiate and enter into an agreement with a third party providing for

125

Table of Contents

a superior proposal, in each case if the Sonus board determines in good faith, after consultation with its legal and financial advisors, that the failure to do so would be inconsistent with the Sonus board's fiduciary duties under applicable law, subject to the payment by Sonus of a termination fee of $14.5 million if Sonus terminates the merger agreement to enter into an agreement for a superior proposal;

•
  the ability of Sonus and GENBAND to complete the mergers, in a timely manner, including the lack of any financing conditionality in the merger agreement, Sonus' ability to specifically enforce GENBAND's obligations under the merger agreement, and the strong contractual commitments of both parties with respect to the regulatory approvals required to complete the merger;
•
  Sonus and GENBAND expect and intend that the Sonus merger will qualify as a reorganization under Section 368(a) of the Code or as a transaction that, taken together with the other mergers, will qualify as a transfer of property to New Solstice described in Section 351 of the Code;
•
  the fact that the merger is subject to the approval of Sonus stockholders; and
•
  the other material terms and conditions of the merger agreement, including, among other things, the representations, warranties and covenants of the parties, the conditions to closing of the merger and the parties' termination rights.

In the course of its deliberations, the Sonus board also identified and considered a variety of risks and countervailing factors weighing negatively against the merger, including the following material factors:

•
  the risk that the significant synergies and other benefits expected to result from the mergers may not be fully realized, including if governmental entities impose conditions on Sonus and GENBAND that adversely impact the ability of the combined company to realize these synergies and other benefits;
•
  the challenges inherent in combining the businesses, operations and workforces of Sonus and GENBAND, including the potential for unforeseen difficulties in integrating operations and systems and the possible distraction of management attention for an extended period of time;
•
  that the combined company will incur $22.5 million of indebtedness payable to GENBAND shareholders, other than GB and GB II, in the form of the promissory note in connection with the mergers;
•
  that, notwithstanding the provisions of the stockholders agreement and the New Solstice charter, the OEP Stockholders will be able to exert significant influence on the combined company by virtue of their ownership of a significant percentage of the outstanding shares of New Solstice common stock, including with respect to major transactions that require stockholder action;
•
  the possible disruption to Sonus' business that may result from the announcement of the transaction and the risk that, despite the efforts of Sonus prior to the consummation of the merger, Sonus and GENBAND may not be able to retain key personnel during the transition and/or following the mergers;
•
  the potential for management focus and resources being diverted from operational matters and other strategic opportunities prior to closing and abiding by the terms of the merger agreement restricting the operation of Sonus' business during the period between the signing of the merger agreement and the completion of the mergers, which could lead to the loss of business opportunities for Sonus;

126

Table of Contents

•
  the risk that GENBAND's financial profile could change between the date of the merger agreement and the completion of the mergers, which could impact the value of the combined company's common stock that Sonus stockholders will receive as consideration;
•
  the risk that the termination fee of $14.5 million to be paid to GENBAND if the merger agreement is terminated under circumstances specified in the merger agreement may discourage other parties that may otherwise have an interest in a business combination with Sonus (see the section entitled "The Merger Agreement—Termination Fee");
•
  the terms of the merger agreement that place limitations on the ability of Sonus to maintain, initiate or solicit or knowingly encourage or facilitate (including by way of furnishing information which has not been previously publicly disseminated) any inquiries with respect to, or the making of any proposal which constitutes, or would reasonably be expected to lead to, a Sonus acquisition proposal (see the section entitled "The Merger Agreement—No Solicitation—No Solicitation by Sonus");
•
  the substantial costs to be incurred in connection with the transaction, including the costs of integrating the businesses of Sonus and GENBAND and the transaction expenses arising from the merger;
•
  the risk that Sonus stockholders or GENBAND shareholders may vote against adoption of the merger agreement, particularly in light of the possibility that certain shareholders or stockholders (as applicable) of the GENBAND parties, by operation of the GENBAND liquidation waterfall, may not receive any consideration in the mergers; and
•
  the risks of the type and nature described in the section of this joint proxy statement/prospectus entitled "Risk Factors."

The Sonus board also considered the interests that the executive officers and directors of Sonus have with respect to the mergers in addition to their interests as stockholders of Sonus generally (see the section entitled "The Mergers—Interests of Directors and Executive Officers in the Transactions—Interests of Directors and Executive Officers of Sonus in the Transactions").

The Sonus board concluded that the negative factors and potential detriments associated with the proposed transaction with GENBAND are significantly outweighed by the positive factors and potential benefits that it expects the Sonus stockholders to achieve as a result of the transaction, including the Sonus board's belief that the proposed transaction would mitigate the risks and uncertainties affecting the future prospects of Sonus as a standalone company.

Accordingly, after careful consideration, the Sonus board unanimously (i) determined that the merger agreement and the transactions contemplated thereby, including without limitation the mergers, are advisable, fair to and in the best interests of Sonus and the Sonus stockholders, (ii) adopted and approved the merger agreement and the transactions contemplated thereby, and (iii) directed that the merger agreement be submitted to Sonus stockholders for their adoption and recommended that the Sonus stockholders adopt the merger agreement in accordance with applicable law.

Although the foregoing discussion sets forth the material factors considered by the Sonus board in reaching its recommendation, it is not intended to be exhaustive and may not include all of the factors considered by the Sonus board, and each director may have considered different factors or given different weight to each factor. The above factors are not presented in any order of priority. In view of the variety of factors, the amount of information and the complexity of the matters considered, the Sonus board did not find it practicable to, and did not, make specific assessments of, or assign relative weights to, the specific factors considered in reaching its recommendation. The explanation of the reasoning of the Sonus board and certain information presented in this section are forward-looking in

127

Table of Contents

nature and should be read in light of the factors discussed in the section entitled "Cautionary Statement Regarding Forward-Looking Statements" of this joint proxy statement/prospectus.

The Sonus board unanimously recommends that the Sonus stockholders vote (i) "FOR" the Sonus merger proposal, (ii) "FOR" each of the Sonus governance-related proposals, (iii) "FOR" the Sonus adjournment proposal and (iv) "FOR" the Sonus executive compensation proposal.

Certain Prospective Financial Information of Sonus and GENBAND

Although Sonus has historically provided limited short-term financial guidance publicly, neither Sonus nor GENBAND as a matter of course makes public long-term financial forecasts as it relates to its projected revenues, earnings or other financial metrics due to the unpredictability and uncertainty of the underlying assumptions and estimates. However, in connection with their review of the mergers, the Sonus board and Evercore, Sonus' financial advisor, and the GENBAND board and Guggenheim Securities, GENBAND's financial advisor, considered certain prospective financial information of Sonus and GENBAND, including estimated cost synergies that are anticipated to be achieved as a result of the mergers. This prospective financial information is summarized below.

This prospective financial information was not prepared for the purpose of public disclosure, nor was it prepared in compliance with published guidelines of the SEC, or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of financial forecasts, but in the view of Sonus management and GENBAND management, was prepared on a reasonable basis, reflects the best currently available estimates and judgments, and presents, to the best of Sonus management's and GENBAND management's knowledge and belief, the expected course of action and the expected future financial performance of Sonus and GENBAND and the estimated cost synergies to be derived in connection with the mergers. The inclusion of this prospective financial information below should not be regarded as an indication that Sonus or the Sonus board or GENBAND or the GENBAND board, considered, or currently considers, such information to be a reliable predictor of actual future results. Although Sonus management and GENBAND management believe there is a reasonable basis for this prospective financial information, Sonus and GENBAND caution stockholders that future results could be materially different from the prospective financial information presented below. The summary of this prospective financial information is not being included in this joint proxy statement/prospectus to influence your decision whether to vote for the Sonus merger proposal or the GENBAND merger proposals, but because this prospective financial information was, to the extent indicated below, made available to Sonus, the Sonus board and its financial advisor, and to GENBAND, the GENBAND board and its financial advisor, in connection with the consideration and evaluation of the mergers and the merger agreement. Neither Sonus' nor GENBAND's independent registered public accounting firm, nor any other independent accountant, has examined, compiled or performed any procedures with respect to the accompanying prospective financial information or expressed any opinion or any other form of assurance on such information or its achievability, and they assume no responsibility for and have disclaimed any association with such information.

The prospective financial information presented below is subjective in many respects and, as a result, subject to interpretation. While presented with numeric specificity, this prospective financial information is based on numerous variables and assumptions that are inherently uncertain and may be beyond the control of the management of Sonus, GENBAND and/or New Solstice. Important factors that may affect actual results and cause actual results to differ from this prospective financial information include, but are not limited to, risks and uncertainties relating to Sonus', GENBAND's or the combined company's businesses (including their ability to achieve strategic goals, objectives and targets over applicable periods), industry performance, the regulatory environment, general business and economic conditions, the ability of Sonus and GENBAND to integrate their businesses successfully and to achieve anticipated synergies, and other factors described under "Cautionary Statement

Regarding Forward-Looking Statements" beginning on page 55 of this joint proxy statement/prospectus. See also "Where you Can Find More Information" and "Risk Factors" beginning on pages 350 and 57, respectively, of this joint proxy statement/prospectus. This prospective financial information also reflects assumptions as to certain business decisions that are subject to change. As a result, actual results may differ materially from this prospective financial information. Accordingly, there can be no assurance that any forecasts and/or synergies will be realized or that actual results will not be significantly lower or higher than estimated. Portions of the prospective financial information cover multiple years. Such information by its nature becomes less predictive with each successive year.

The prospective financial information presented below contains certain non-GAAP financial measures that Sonus and GENBAND believe are helpful in understanding the respective past financial performance and future projected financial results of the respective parties to the mergers. The non-GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable U.S. GAAP measures.

Sonus Management Forecasts

Sonus management prepared and provided to GENBAND, as well as to Sonus' and GENBAND's respective financial advisors and boards of directors, non-public, unaudited prospective internal financial information regarding Sonus' anticipated future operations for the fiscal years ending December 31, 2017 through 2021. This unaudited prospective financial information (which we refer to as the Sonus management forecasts) was prepared and provided in May 2017, treating Sonus on a stand-alone basis, without giving effect to, and as if Sonus never contemplated, the mergers including the impact of negotiating or executing the mergers, the expenses that may be incurred in connection with consummating the mergers, the potential synergies that may be achieved by the combined company as a result of the mergers, the effect of any business or strategic decision or action that has been or will be taken as a result of the mergers agreement having been executed, or the effect of any business or strategic decisions or actions which would likely have been taken if the merger agreement had not been executed but which were instead altered, accelerated, postponed or not taken in anticipation of the mergers.

Adjusted GENBAND Forecasts

In May 2017, Sonus management prepared and provided to Evercore and the Sonus board, non-public, unaudited prospective internal financial information regarding GENBAND's anticipated future operations for the fiscal years ending December 31, 2017 through 2021, which was based on the modified GENBAND management forecasts but which reflected adjustments that Sonus management deemed appropriate and consistent with assumptions used by Sonus management in preparing the Sonus management forecasts. These adjustments consisted of reducing GENBAND's revenue growth forecasts to more closely reflect historical trends and market growth rates, as well as moderating GENBAND's forecasted gross margin improvements and operating expense reductions, as a percentage of revenue, to reflect the lowered revenues being projected in the revised forecast. We refer to this information as the adjusted GENBAND forecasts. The adjusted GENBAND forecasts were not made available to GENBAND or its financial advisor.

The following table summarizes the adjusted GENBAND forecasts:

Estimated Cost Synergies

In May 2017, Sonus' management prepared with the assistance of GENBAND's management certain estimates of annual cost synergies expected to be realized following the completion of the mergers, which we refer to in this section as the Sonus management estimated cost synergies. The Sonus management estimated cost synergies are not reflected in the Sonus management forecasts, the GENBAND management forecasts or the adjusted GENBAND forecasts, each of which relates to stand-alone operations. Sonus provided the Sonus management estimated cost synergies to Evercore to use in connection with its financial analyses and to the Sonus board.

The Sonus management estimated cost synergies assumed that the mergers would be consummated and that the expected benefits of the mergers would be realized, including that no restrictions, terms or other conditions would be imposed in connection with the receipt of any necessary governmental, regulatory or other approvals or consents in connection with the consummation of the proposed mergers, including any divestitures or other actions contemplated by the merger agreement. See the sections entitled "Cautionary Statement Regarding Forward-Looking Statements" beginning on page 55 of this joint proxy statement/prospectus and "Risk Factors—New Solstice May Fail to Realize the Anticipated Benefits of the Mergers" beginning on page 64 of this joint proxy statement/prospectus for further information regarding the uncertainties and factors associated with realizing the Sonus management estimated cost synergies in connection with the mergers.

The following table summarizes the Sonus management estimated cost synergies:

Opinions of Sonus' Financial Advisor

In connection with the mergers, Sonus retained Evercore to act as a financial advisor to Sonus and the Sonus board. As part of this engagement, Sonus requested that Evercore evaluate the fairness of the Sonus exchange ratio, from a financial point of view, to the holders of Sonus common stock and the fairness of the GENBAND total consideration (defined as the aggregate amount of New Solstice common stock and the promissory note to be issued in connection with the GENBAND mergers), taking into account a significant portion of such GENBAND total consideration is in the form of New Solstice common stock, from a financial point of view, to Sonus. On May 22, 2017, at a meeting of the Sonus board, Evercore rendered its oral opinion, subsequently confirmed by delivery of a written opinion (which we refer to as the First Evercore Opinion) that, based upon and subject to the factors, procedures, assumptions, qualifications and limitations set forth in its opinion, as of such date, the Sonus exchange ratio was fair, from a financial point of view, to the holders of Sonus common stock and the GENBAND total consideration, taking into account a significant portion of such GENBAND total consideration is in the form of New Solstice common stock, was fair, from a financial point of view, to Sonus.

On June 20, 2017, management of Sonus furnished to Evercore revised estimates of the present value of the net operating losses of Sonus and the GENBAND parties, together with corresponding revisions to the applicable tax rate estimates, in each case as prepared and revised by management of Sonus (which we refer to collectively as the Management Revised Tax Rate and NOL Estimates). Sonus requested that Evercore evaluate the fairness of the Sonus exchange ratio, from a financial point of view, to the holders of Sonus common stock and the fairness of the GENBAND total consideration, taking into account a significant portion of such GENBAND total consideration is in the form of New Solstice common stock, from a financial point of view, to Sonus, in each case, as of May 22, 2017 and taking into account the Management Revised Tax Rate and NOL Estimates.

Evercore performed an additional analysis, taking into account the Management Revised Tax Rate and NOL Estimates and otherwise using information available as of May 22, 2017 to be consistent with information originally analyzed by Evercore and made available to the Sonus board when it made its decision to enter into the merger agreement. On June 22, 2017, at a meeting of the Sonus board, Evercore rendered its oral opinion, subsequently confirmed by delivery of a written opinion (which we

133

Table of Contents

refer to as the Second Evercore Opinion) that, based upon and subject to the factors, procedures, assumptions, qualifications and limitations set forth in its opinion, as of May 22, 2017 and taking into account the Management Revised Tax Rate and NOL Estimates, the Sonus exchange ratio was fair, from a financial point of view, to the holders of Sonus common stock and the GENBAND total consideration, taking into account a significant portion of such GENBAND total consideration is in the form of New Solstice common stock, was fair, from a financial point of view, to Sonus.

The full text of the First Evercore Opinion, dated as of May 22, 2017, and the Second Evercore Opinion, dated as of June 22, 2017, which set forth, among other things, the procedures followed, assumptions made, matters considered and qualifications and limitations on the scope of review undertaken in rendering such opinions, is attached as Annex D to this joint proxy statement/prospectus. The following summaries of Evercore's opinions are qualified in their entirety by reference to the full text of the opinions, which is incorporated herein by reference. You are urged to read Evercore's opinions carefully and in their entirety. Evercore's opinions were addressed to, and provided for the information and benefit of, the Sonus board (in its capacity as such) in connection with its evaluation of whether the Sonus exchange ratio was fair, from a financial point of view, to the holders of Sonus common stock (after giving effect to the completion of the mergers) and whether the GENBAND total consideration, taking into account a significant portion of such GENBAND total consideration is in the form of New Solstice common stock, was fair, from a financial point of view, to Sonus and do not address any other aspects or implications of the mergers. The opinions do not constitute a recommendation to the Sonus board or to any other persons in respect of the mergers, including as to how any holder of shares of Sonus common stock should vote or act in respect of the mergers. Evercore's opinions do not address the relative merits of the mergers as compared to other business or financial strategies that might be available to Sonus, nor do they address the underlying business decision of Sonus to engage in the mergers.

In connection with rendering its opinions and performing its related financial analysis, Evercore, among other things:

•
  reviewed certain publicly available information that Evercore deemed to be relevant, including business and financial information (including research analysts' estimates) relating to Sonus and business information relating to the GENBAND parties;
•
  reviewed certain non-public historical financial statements and other non-public historical financial and operating data relating to Sonus and the GENBAND parties prepared and furnished to, or otherwise discussed with, Evercore by the management of Sonus and the GENBAND parties, respectively;
•
  reviewed certain non-public projected financial data relating to Sonus and the GENBAND parties, as well as certain non-public historical and projected operating data, in each case prepared and furnished to, or otherwise discussed with, Evercore by the management of Sonus and the GENBAND parties, as well as projected financial and operating data relating to the GENBAND parties prepared by the management of Sonus;
•
  discussed the past and current operations, financial projections and current financial condition of (a) Sonus with management of Sonus and (b) the GENBAND parties with management of the GENBAND parties and Sonus (including in each case their views on the risks and uncertainties of achieving such projections);
•
  reviewed and discussed with the respective management of Sonus and the GENBAND parties certain estimates of the present value of the net operating losses, including the Management Revised Tax Rate and NOL Estimates, as applicable, of Sonus and the GENBAND parties prepared for and furnished to, or otherwise discussed with, Evercore by the management of Sonus and the GENBAND parties, respectively;

Table of Contents

•
  reviewed and discussed with the respective management of the Company and the GENBAND parties certain factors that impact pro forma taxes, including estimates of the net operating losses, in each case prepared for and furnished to, or otherwise discussed with, Evercore by their respective managements, to be used after giving effect to the mergers to determine pro forma effective tax rate estimates, which were prepared by or at the direction of and approved by the management of Sonus;
•
  reviewed analyses performed by management of Sonus and the GENBAND parties with respect to cost synergies, including the amount and timing thereof, that Sonus management believes are realizable by the combined company as a result of the mergers (collectively, the "Synergies");
•
  reviewed the reported prices and the historical trading activity of Sonus common stock;
•
  compared the financial performance metrics of Sonus and its stock market trading multiples with those of certain other publicly traded companies that Evercore deemed relevant;
•
  compared the financial performance of the GENBAND parties and the valuation multiples relating to the mergers with those of certain other transactions that Evercore deemed relevant;
•
  reviewed a draft of the merger agreement dated May 21, 2017, the stockholders agreement, the voting agreement and the registration rights agreement, each in substantially final form, and assumed that the final form of each such agreement will not vary in any respect material to Evercore's analysis; and
•
  performed such other analyses and examinations and considered such other factors that Evercore deemed appropriate.

For purposes of its analysis and opinions, Evercore assumed and relied upon, without undertaking any independent verification of, the accuracy and completeness of all of the information publicly available, and all of the information supplied or otherwise made available to, discussed with, or reviewed by Evercore, and Evercore has assumed no liability thereof. With respect to the projected financial data relating to Sonus and the GENBAND parties referred to above (including the Synergies), Evercore assumed that they had been reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the managements of Sonus and the GENBAND parties as to the future financial performance of each of Sonus and the GENBAND parties, under the assumptions reflected therein and as to the Synergies, including the amounts and timing of the realization of such Synergies.

Evercore expressed no view as to any projected financial data relating to Sonus or the GENBAND parties or the Synergies or the assumptions on which they are based. Evercore relied, at Sonus' direction, without independent verification, upon the assessments of the management of Sonus and the management of the GENBAND parties as to the Synergies, including the amount and timing of the realization of such Synergies.

For purposes of rendering each of its opinions, Evercore assumed, in all respects material to its analysis, that the representations and warranties of each party contained in the merger agreement were true and correct, that each party will perform all of the covenants and agreements required to be performed by it under the merger agreement and that all conditions to the consummation of the mergers will be satisfied without material waiver or modification thereof. Evercore further assumed that all governmental, regulatory or other consents, approvals or releases necessary for the consummation of the mergers will be obtained without any material delay, limitation, restriction or condition that would have an adverse effect on Sonus, the GENBAND parties or the consummation of the mergers or materially reduce the benefits to the holders of shares of Sonus common stock of the mergers. Evercore also assumed that the executed merger agreement would not differ in any material respect from the draft merger agreement dated May 21, 2017 reviewed by Evercore.

Table of Contents

Evercore did not make or assume any responsibility for making any physical inspection, independent valuation or appraisal of the assets or liabilities of Sonus or the GENBAND parties, nor was Evercore furnished with any such inspection, valuation or appraisal, nor did Evercore evaluate the solvency or fair value of Sonus or the GENBAND parties under any state, federal or foreign laws relating to bankruptcy, insolvency or similar matters. Evercore's opinion is necessarily based upon information made available to it as of May 22, 2017 (except the Management Revised Tax Rate and NOL Estimates used solely in connection with the Second Evercore Opinion) and financial, economic, market and other conditions as they existed and as could be evaluated on May 22, 2017. Developments subsequent to May 22, 2017 may affect Evercore's opinions and Evercore did not undertake any obligation to update, revise or reaffirm either of its opinions.

Evercore was not asked to pass upon, and expressed no opinion with respect to, any matter other than the fairness to the holders of Sonus common stock, from a financial point of view, of the Sonus exchange ratio or the fairness to Sonus, from a financial point of view, of the GENBAND total consideration, taking into account a significant portion of such GENBAND total consideration is in the form of New Solstice common stock. Evercore did not express any view on, and neither of its opinions addressed, the fairness of the mergers to, or any consideration received in connection therewith by, the holders of any securities, creditors or other constituencies of Sonus or the GENBAND parties, nor as to the fairness of the amount or nature of any compensation to be paid or payable to any of the officers, directors or employees of Sonus or any other party to the merger agreement, or any class of such persons, whether relative to the GENBAND total consideration or otherwise.

Evercore assumed that any modification to the structure of the transaction would not vary its analysis in any material respect. Evercore's opinions did not address the relative merits of the mergers as compared to other business or financial strategies that might be available to Sonus, nor did they address the underlying business decision of Sonus to engage in the mergers. Evercore's opinions did not constitute a recommendation to the Sonus board or to any other persons in respect of the mergers, including as to how any holder of shares of Sonus common stock should vote or act in respect of the mergers. Evercore expressed no opinion as to the price at which shares of Sonus common stock will trade at any time. Evercore is not a legal, regulatory, accounting or tax expert and therefore assumed the accuracy and completeness of assessments by Sonus and its advisors with respect to legal, regulatory, accounting and tax matters.

Selected Peer Trading Analysis

In performing a selected peer trading analysis of Sonus and the GENBAND parties, Evercore reviewed and compared certain financial, operating and market information relating to Sonus and the GENBAND parties to corresponding information of the publicly traded companies listed in the table below, which Evercore deemed most relevant to consider in relation to Sonus and the GENBAND parties, respectively, based on its professional judgment and experience, because they are public companies with operations that for purposes of this analysis Evercore considered similar to the operations of one or more of the business lines of Sonus and the GENBAND parties, respectively.

|  | Selected Public Company Peers
--- | --- | ---
Traditional Networking |  | Cisco, Nokia, Ericsson, Juniper, Ciena, Infinera, Adtran, Audiocodes

Evercore reviewed, among other things, total enterprise value ("TEV") of the selected companies as a multiple of estimated earnings before interest, taxes, depreciation and amortization ("EBITDA"), as well as equity value net of net cash of the selected companies as a multiple of net income net of net cash ("P/E") for estimated calendar year 2017 and estimated calendar year 2018. Enterprise values were calculated for the purpose of this analysis as equity value (based on the per share closing price of each selected company on May 19, 2017, multiplied by the fully diluted number of such company's outstanding equity securities on such date), plus debt, plus minority interest, less cash and cash equivalents (in the case of debt, minority interest, cash and cash equivalents, as set forth on the most recently publicly available balance sheet of such company, and in the case of minority interest, where applicable). Equity values net of cash were calculated for the purpose of this analysis as equity value (based on the per share closing price of each selected company on May 19, 2017, multiplied by the fully diluted number of such company's outstanding equity securities on such date), plus debt, less cash and cash equivalents (in the case of debt, cash and cash equivalents, as set forth on the most recently publicly available balance sheet of such company). Net income net of cash was calculated as cash net income less post-tax net interest income. The financial data of the selected peer companies used by Evercore for this analysis were based on publicly available research analysts' estimates. The following table summarizes the TEV of the selected companies as a multiple of estimated EBITDA, as well as P/E, for estimated calendar year 2017 and estimated calendar year 2018:

Evercore applied a reference range of EBITDA multiples of 9.0x to 11.0x and 10.0x to 12.0x to the GENBAND parties and Sonus, respectively, as well as a reference range of P/E multiples of 14.0x to 19.0x to Sonus in each case derived by Evercore based on its review of the peer companies selected and its experience and professional judgment, to the estimated EBITDA for each of the GENBAND parties and Sonus and the estimated net income net of net cash for Sonus for the year ending December 31, 2017. In arriving at the reference range for both EBITDA and P/E multiples for the years ending December 31, 2017 and December 31, 2018, Evercore selected for comparison purposes, companies it considered to be similar to the GENBAND parties, based on such factors as participating in similar lines of businesses and having similar operations, operating in the same industry and serving similar customers, having similar financial performance, or having other relevant or similar

characteristics to the GENBAND parties and Sonus. It is important to note that none of the selected companies reviewed are identical to either the GENBAND parties or Sonus. Accordingly, a complete understanding of the results cannot be limited to a quantitative analysis of such results; rather, such understanding necessarily involves complex considerations and judgments concerning the differences in the financial and operating characteristics of the selected companies compared to those of the GENBAND parties and Sonus. In the case of the GENBAND parties, estimated EBITDA were based on the projections provided by the management of the GENBAND parties and adjusted projections of the GENBAND parties provided by the management of Sonus. In the case of Sonus, estimated EBITDA and net income net of net cash were based on the projections provided by the management of Sonus. Using the 2017 EBITDA multiples, this analysis indicated an implied equity value reference range for the GENBAND parties of approximately $382 million to $471 million without Synergies and approximately $893 million to $1,096 million with Synergies based on projections provided by the management of the GENBAND parties; and approximately $325 million to $401 million without Synergies and approximately $836 million to $1,026 million with Synergies based on adjusted projections of the GENBAND parties provided by the management of Sonus, and indicated an implied equity value per-share reference range for Sonus of approximately $7.43 to $8.26 and an implied equity value reference range of approximately $386 million to $429 million. Using the 2017 P/E multiples, this analysis indicated an implied equity value per-share reference range for Sonus of approximately $5.82 to $7.01 and an implied equity value reference range of approximately $302 million to $364 million.

Evercore applied a reference range of EBITDA multiples of 8.0x to 10.0x and 9.0x to 11.0x to the GENBAND parties and Sonus, respectively, as well as a reference range of P/E multiples of 12.0x to 16.0x to Sonus in each case derived by Evercore based on its review of the peer companies selected and its experience and professional judgment, to the estimated EBITDA for each of the GENBAND parties and Sonus and the estimated net income net of net cash for Sonus for the year ending December 31, 2018. In the case of the GENBAND parties, estimated EBITDA were based on the projections provided by the management of the GENBAND parties and adjusted projections of the GENBAND parties provided by the management of Sonus. In the case of Sonus, estimated EBITDA and net income net of net cash were based on the projections provided by the management of Sonus. Using the 2018 EBITDA multiples, this analysis indicated an implied equity value reference range for the GENBAND parties of approximately $419 million to $528 million without Synergies and approximately $873 million to $1,096 million with Synergies based on projections provided by the management of the GENBAND parties; and approximately $217 million to $276 million without Synergies and approximately $672 million to $844 million with Synergies based on adjusted projections of the GENBAND parties provided by the management of Sonus, and an implied equity value per-share reference range for Sonus of approximately $7.82 to $8.82 and an implied equity value reference range of approximately $406 million to $458 million. Using the 2018 P/E multiples, this analysis indicated an implied equity value per-share reference range for Sonus of approximately $6.31 to $7.58 and an implied equity value reference range of approximately $327 million to $394 million.

No company utilized in the peer company trading analysis is identical to Sonus or the GENBAND parties. Accordingly, an analysis of the results of the foregoing necessarily involves complex considerations and judgments concerning differences in financial, operating and market characteristics of Sonus and the GENBAND parties and other factors that could affect the public trading value of the companies to which they are being compared. In evaluating the peer companies selected, Evercore made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of Sonus and the GENBAND parties, such as the impact of competition on Sonus and the GENBAND parties and the industry generally, industry growth and the absence of any adverse material change in the financial conditions and prospects of Sonus, the GENBAND parties, the industry or the financial markets in general. Mathematical analysis, such as determining the mean, median or average, is not in itself a meaningful method of using peer company trading data.

Implied Ownership Interest—Evercore used the resulting equity value reference ranges to calculate the implied ownership interest for Sonus for the 2017 and 2018 EBITDA multiple by dividing the highest respective equity value for the GENBAND parties, plus the average respective equity value for Sonus, less the promissory note to be paid in connection with the mergers, by the average respective equity value for Sonus for the low end of the implied Sonus ownership range in each case and dividing the lowest respective equity value for the GENBAND parties, plus the average respective equity value for Sonus, less the promissory note, by the average respective equity value for Sonus for the high end of the implied Sonus ownership range in each case. This analysis indicated implied Sonus ownership reference ranges of the shares of New Solstice's common stock issued and outstanding immediately

after the closing of the transactions contemplated by the merger agreement based on the different public company multiples and summarized in the following table:

Selected Public Company Multiple |  | Selected Public Company Reference Range for GENBAND |  | Selected Public Company Reference Range for Sonus |  | Implied Sonus Ownership Reference Range
--- | --- | --- | --- | --- | --- | ---
TEV / EBITDA 2017E—Management Projections |  |  | 9.0x - 11.0x |  |  | 10.0x - 12.0x |  | 47.6% - 53.1%

Evercore compared these implied Sonus ownership interests to the transaction ownership split of the shares of New Solstice's common stock of approximately 50% for holders of Sonus common stock and 50% to the GENBAND parties.

Selected Precedent Transaction Analysis

Evercore performed an analysis of selected precedent transactions to compare multiples paid in other transactions to the multiples implied in the mergers. Evercore analyzed 17 merger and acquisition transactions that were announced between 2009 and 2016 involving companies in the traditional / next generation networking sectors of the technology industry, which were selected based on Evercore's professional judgment.

While none of the companies that participated in the selected precedent transactions is directly comparable to the GENBAND parties and none of the transactions in the selected precedent transactions analysis is directly comparable to the mergers, Evercore selected these transactions because each of the target companies was involved in the traditional / next generation networking sectors of the technology industry and had operating characteristics and products that for purposes of analysis may be considered similar to certain of the GENBAND parties' operating characteristics and products.

For each of the selected transactions, Evercore reviewed transaction values and calculated the TEV implied for each target company based on the consideration paid in the selected transaction, as a multiple of the target company's current year revenue (in each case, primarily calculated for the 12-month period prior to the latest available data on the quarter preceding the date of announcement of such transaction). In circumstances where such multiples were unavailable, last quarter annualized revenue, fourth quarter annualized revenue or Wall Street research estimates for current year revenue were utilized.

Table of Contents

Evercore's analysis indicated mean, median, high and low TEV to current year revenue multiples of 2.54x, 1.78x, 7.87x and 0.38x, respectively. The selected precedent transactions are set forth in the table below:

Date Announced |  | Acquiror |  | Target
--- | --- | --- | --- | ---
May 23, 2016 |  | Siris Capital |  | Xura

September 16, 2010 |  | Calix |  | Occam
October 12, 2009 |  | Cisco |  | Starent

Evercore then applied a reference range of estimated revenue multiples of 2.0x to 3.0x, derived by Evercore based on its review of the selected precedent transactions and its experience and professional judgment, to the estimated revenue of the GENBAND parties, for 12 months ending March 31, 2017. This analysis indicated an implied equity value range for the GENBAND parties of $822 million to $1,242 million.

Discounted Cash Flow Analyses

The GENBAND Parties

Evercore performed a discounted cash flow analysis of the GENBAND parties to calculate the estimated present value of the standalone unlevered, after-tax free cash flows that the GENBAND parties was projected to generate from March 31, 2017 through calendar year 2021, based on financial projections of the GENBAND parties that were provided by management of GENBAND parties and adjusted financial projections of the GENBAND parties that were provided by Sonus management.

Evercore also calculated a terminal value for the GENBAND parties by applying a perpetuity growth rate of 2.0% to 4.0%, to the unlevered, after-tax free cash flows in the terminal year. The perpetuity growth rate was based on the professional judgment of Evercore given the nature of the GENBAND parties, their businesses, and growth rates in the global communications networking industry. The cash flows and terminal values for the GENBAND parties were then discounted to present value using a discount rate of 11.0% to 13.0%, based on an estimate of the GENBAND parties' weighted average cost of capital, and net operating losses ("NOLs") (based on assumptions provided by management of the GENBAND parties and Sonus management) were discounted to present value using a discount rate of 13%, to derive respective ranges of implied enterprise values for GENBAND. The discount rates were based on Evercore's analysis of the capital structures and costs of equity and debt of publicly traded companies that may be considered similar to the GENBAND parties. Ranges of implied equity values for the GENBAND parties were then calculated by reducing the respective ranges of implied enterprise values by the amount of the GENBAND parties' projected net debt (calculated as debt and debt-like items less cash and cash equivalents and less present value of

141

Table of Contents

NOLs) as of March 31, 2017. Evercore performed this analysis for the GENBAND parties (a) on a standalone basis and (b) with the inclusion of Synergies estimated by management of the GENBAND parties and Sonus management to be realized from the mergers, attributing 100% of the value of such Synergies to the GENBAND parties. Evercore's analysis indicated an implied equity value reference ranges for the GENBAND parties on a standalone basis based on projections provided by management of the GENBAND parties and adjusted projections of the GENBAND parties provided by Sonus management summarized in the following table:

GENBAND Financial Projections |  | WACC |  | Perp. Growth Rate |  | Implied Equity Valuation Range of the GENBAND Parties
--- | --- | --- | --- | --- | --- | ---
Management Projections |  | 11.0% - 13.0% |  | 2.0% - 4.0% |  | $396mm - $637mm
Adjusted Projections |  | 11.0% - 13.0% |  | 2.0% - 4.0% |  | $135mm - $226mm
Management Projections (with Synergies) |  | 11.0% - 13.0% |  | 2.0% - 4.0% |  | $692mm - $1,085mm
Adjusted Projections (with Synergies) |  | 11.0% - 13.0% |  | 2.0% - 4.0% |  | $431mm - $676mm

Sonus

Evercore performed a discounted cash flow analysis of Sonus to calculate the estimated present value of the standalone unlevered, after-tax free cash flows that Sonus was projected to generate from March 31, 2017 through calendar year 2021, based on financial projections of Sonus that were provided by Sonus management.

Evercore also calculated a terminal value for Sonus by applying a perpetuity growth rate, in each case based on its professional judgment given the nature of Sonus and its business and industry, of 2.0% to 4.0% to the unlevered, after-tax free cash flows in the terminal year. The cash flows and the terminal values for Sonus were then discounted to present value using a discount rate of 11.0% to 13.0%, based on an estimate of Sonus' weighted average cost of capital, and NOLs (based on assumptions provided by Sonus management) were discounted to present value using a discount rate of 13%, to derive a range of implied enterprise values for Sonus. Range of implied equity values for Sonus were then calculated by reducing the range of implied enterprise values by the amount of Sonus' projected net debt (calculated as debt and debt-like items less cash and cash equivalents and less present value of NOLs) as of March 31, 2017 as provided by Sonus management. Evercore's analysis indicated an implied per-share equity value reference range for Sonus on a standalone basis of approximately $5.65 to $7.00 and an implied equity value reference range of approximately $294 million to $364 million.

Implied Ownership Interest—Based on the implied equity value reference ranges, Evercore also calculated the implied ownership interest for Sonus for the perpetuity growth rate case by dividing the highest respective equity value for the GENBAND parties, plus the average respective equity value for Sonus, less the promissory note, by the average respective equity value for Sonus for the low end of the implied Sonus ownership range in each case and dividing the lowest respective equity value for the GENBAND parties, plus the average respective equity value for Sonus, less the promissory note, by the average respective equity value for Sonus for the high end of the implied Sonus ownership range in each case. This analysis indicated implied Sonus ownership reference ranges of the shares of New Solstice's common stock issued and outstanding immediately after the closing of the transactions contemplated by the merger agreement based on financial projections of the GENBAND parties

provided by management of the GENBAND parties and based on adjusted financial projections of the GENBAND parties provided by Sonus management, as summarized in the following table:

GENBAND Financial Projections |  | Implied Valuation Range of the GENBAND Parties |  | Implied Sonus Ownership Reference Range
--- | --- | --- | --- | ---
Management Projections |  | $396mm - $637mm |  | 34.9% - 46.8%
Adjusted Projections |  | $135mm - $226mm |  | 61.7% - 74.6%
Management Projections (with Synergies) |  | $692mm - $1,085mm |  | 23.6% - 32.9%
Adjusted Projections (with Synergies) |  | $431mm - $676mm |  | 33.5% - 44.6%

Evercore compared these implied Sonus ownership interest to the transaction ownership split of 50% for Sonus and 50% to the GENBAND parties.

Net Present Value of Future Stock Price Analysis

Evercore performed an illustrative analysis of the net present value of the future stock price of Sonus, which is designed to provide an indication of the present value of a theoretical future value of a company as a function of such company's estimated future EBITDA and its assumed TEV to NTM EBITDA multiple, as well as such company's estimated future net income net of net cash and its assumed NTM P/E multiple. Evercore used financial projections of Sonus derived from assumptions provided by Sonus management through calendar year 2018.

Evercore reviewed, among other things, TEV of the selected companies as a multiple of estimated EBITDA, as well as P/E for NTM as of March 31, 2017. Enterprise values were calculated for the purpose of this analysis as equity value (based on the per share closing price of each selected company on May 19, 2017, multiplied by the fully diluted number of such company's outstanding equity securities on such date), plus debt, plus minority interest, less cash and cash equivalents (in the case of debt, minority interest, cash and cash equivalents, as set forth on the most recently publicly available balance sheet of such company, and in the case of minority interest, where applicable). Equity values net of cash were calculated for the purpose of this analysis as equity value (based on the per share closing price of each selected company on May 19, 2017, multiplied by the fully diluted number of such company's outstanding equity securities on such date), plus debt, less cash and cash equivalents (in the case of debt, cash and cash equivalents, as set forth on the most recently publicly available balance sheet of such company). Net income net of cash was calculated as cash net income less post-tax net interest income. The financial data of the selected peer companies used by Evercore for this analysis were based on publicly available research analysts' estimates. The following table summarizes the TEV of the selected companies as a multiple of estimated EBITDA, as well as P/E, for NTM as of March 31, 2017.

|  | Traditional Networking |  | Next Generation Networking |
--- | --- | --- | --- | --- | ---
|  | NTM TEV / EBITDA |  | NTM P/E Net of Net Cash |  | NTM TEV / EBITDA |  | NTM P/E Net of Net Cash |
High |  |  | 14.6x |  |  | 23.5x |  |  | 21.8x |  |  | 35.7x |
Mean |  |  | 9.3x |  |  | 15.6x |  |  | 11.7x |  |  | 18.6x |
Median |  |  | 8.8x |  |  | 13.4x |  |  | 9.6x |  |  | 14.6x |
Low |  |  | 6.9x |  |  | 10.2x |  |  | 7.1x |  |  | 13.2x |

With the estimated EBITDA and assumed TEV to NTM EBITDA multiple, Evercore first multiplied the EBITDA estimate by a range of TEV to NTM EBITDA multiples of 9.5x to 11.5x to calculate the implied future enterprise values based on its review of the peer companies selected and its experience and professional judgment. Evercore then calculated the implied future equity values for Sonus as of December 31, 2018 by reducing the implied future enterprise values by the amount of Sonus' projected future net debt (calculated as debt and debt-like items less cash and cash equivalents and less present value of NOLs) as of December 31, 2018. Evercore then discounted the projected per-share equity value as of December 31, 2018 using a discount rate of 13.0% based on Evercore's

143

Table of Contents

analysis of the cost of equity for Sonus. This analysis resulted in an implied per-share equity value reference range of approximately $7.94 to $8.97 and an implied equity value reference range of approximately $412 million to $466 million.

With the estimated net income net of net cash and assumed NTM P/E multiple, Evercore first multiplied the net income net of net cash estimate by a range of NTM P/E multiples of 13.0x to 18.0x to calculate the implied future equity values net of cash based on its review of the peer companies selected and its experience and professional judgment. Evercore then calculated the implied future equity values for Sonus as of December 31, 2018 by increasing the implied future equity values net of cash by the amount of Sonus' projected future net cash (calculated as cash and cash equivalents less debt) as of December 31, 2018. Evercore then discounted the projected per-share equity value as of December 31, 2018 using the discount rate of 13.0% as determined above. This analysis resulted in an implied per-share equity value reference range of approximately $7.13 to $8.96 and an implied equity value reference range of approximately $370 million to $465 million.

Summary of Material Financial Analysis for Second Evercore Opinion

As noted above, on June 20, 2017, management of Sonus provided Evercore with the Management Revised Tax Rate and NOL Estimates in connection with Sonus requesting Evercore to deliver the Second Evercore Opinion. Evercore performed the same analysis with respect to the Second Evercore Opinion as it did with respect to the First Evercore Opinion, but incorporated the Management Revised Tax Rate and NOL Estimates, as applicable. Set forth below is a summary of the material financial and other analyses performed by Evercore and reviewed with the Sonus board on June 22, 2017, in connection with rendering the Second Evercore Opinion. Such summary, however, does not purport to be a complete description of the analyses performed by Evercore. The order of the analyses described and the results of these analyses do not represent relative importance or weight given to these analyses by Evercore. Except as otherwise noted, the following quantitative information, to the extent that it is based on market data, is based on market data that existed on or before May 19, 2017, and is not necessarily indicative of current market conditions.

The following summary of financial analyses includes information presented in tabular format. These tables must be read together with the text of each summary in order to understand fully the financial analyses. The tables alone do not constitute a complete description of the financial analyses. Considering the tables below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of Evercore's financial analyses.

Selected Peer Trading Analysis

In performing a selected peer trading analysis of Sonus and the GENBAND parties, Evercore reviewed and compared certain financial, operating and market information relating to Sonus and the GENBAND parties to corresponding information of the publicly traded companies listed in the table below, which Evercore deemed most relevant to consider in relation to Sonus and the GENBAND parties, respectively, based on its professional judgment and experience, because they are public companies with operations that for purposes of this analysis Evercore considered similar to the operations of one or more of the business lines of Sonus and the GENBAND parties, respectively.

company's outstanding equity securities on such date), plus debt, plus minority interest, less cash and cash equivalents (in the case of debt, minority interest, cash and cash equivalents, as set forth on the most recently publicly available balance sheet of such company, and in the case of minority interest, where applicable). Equity values net of cash were calculated for the purpose of this analysis as equity value (based on the per share closing price of each selected company on May 19, 2017, multiplied by the fully diluted number of such company's outstanding equity securities on such date), plus debt, less cash and cash equivalents (in the case of debt, cash and cash equivalents, as set forth on the most recently publicly available balance sheet of such company). Net income net of cash was calculated as cash net income less post-tax net interest income. The financial data of the selected peer companies used by Evercore for this analysis were based on publicly available research analysts' estimates. The following table summarizes the TEV of the selected companies as a multiple of estimated EBITDA, as well as P/E, for estimated calendar year 2017 and estimated calendar year 2018:

Evercore applied a reference range of EBITDA multiples of 9.0x to 11.0x and 10.0x to 12.0x to the GENBAND parties and Sonus, respectively, as well as a reference range of P/E multiples of 14.0x to 19.0x to Sonus in each case derived by Evercore based on its review of the peer companies selected and its experience and professional judgment, to the estimated EBITDA for each of the GENBAND parties and Sonus and the estimated net income net of net cash for Sonus for the year ending December 31, 2017. In arriving at the reference range for both EBITDA and P/E multiples for the years ending December 31, 2017 and December 31, 2018, Evercore selected for comparison purposes, companies it considered to be similar to the GENBAND parties, based on such factors as participating in similar lines of businesses and having similar operations, operating in the same industry and serving similar customers, having similar financial performance, or having other relevant or similar characteristics to the GENBAND parties and Sonus. It is important to note that none of the selected companies reviewed are identical to either the GENBAND parties or Sonus. Accordingly, a complete understanding of the results cannot be limited to a quantitative analysis of such results; rather, such understanding necessarily involves complex considerations and judgments concerning the differences in the financial and operating characteristics of the selected companies compared to those of the GENBAND parties and Sonus. In the case of the GENBAND parties, estimated EBITDA were based on the projections provided by the management of the GENBAND parties and adjusted projections of the GENBAND parties provided by the management of Sonus. In the case of Sonus, estimated EBITDA and net income net of net cash were based on the projections provided by the management of Sonus. Using the 2017 EBITDA multiples, this analysis indicated an implied equity value reference range for the GENBAND parties of approximately $366 million to $455 million without Synergies and approximately $876 million to $1,079 million with Synergies based on projections provided by the management of the GENBAND parties; and approximately $308 million to $385 million without Synergies and approximately $819 million to $1,009 million with Synergies based on adjusted projections of the GENBAND parties provided by the management of Sonus, and indicated an implied equity value per-share reference range for Sonus of approximately $7.14 to $7.96 and an implied equity value reference range of approximately $370 million to $413 million. Using the 2017 P/E multiples, this analysis indicated an implied equity value per-share reference range for Sonus of approximately $5.82 to $7.01 and an implied equity value reference range of approximately $302 million to $364 million.

Evercore applied a reference range of EBITDA multiples of 8.0x to 10.0x and 9.0x to 11.0x to the GENBAND parties and Sonus, respectively, as well as a reference range of P/E multiples of 12.0x to 16.0x to Sonus in each case derived by Evercore based on its review of the peer companies selected and its experience and professional judgment, to the estimated EBITDA for each of the GENBAND parties and Sonus and the estimated net income net of net cash for Sonus for the year ending December 31, 2018. In the case of the GENBAND parties, estimated EBITDA were based on the projections provided by the management of the GENBAND parties and adjusted projections of the GENBAND parties provided by the management of Sonus. In the case of Sonus, estimated EBITDA and net income net of net cash were based on the projections provided by the management of Sonus. Using the 2018 EBITDA multiples, this analysis indicated an implied equity value reference range for the GENBAND parties of approximately $402 million to $511 million without Synergies and approximately $856 million to $1,079 million with Synergies based on projections provided by the management of the GENBAND parties; and approximately $201 million to $260 million without Synergies and approximately $655 million to $827 million with Synergies based on adjusted projections of the GENBAND parties provided by the management of Sonus, and an implied equity value per-share reference range for Sonus of approximately $7.52 to $8.52 and an implied equity value reference range of approximately $390 million to $442 million. Using the 2018 P/E multiples, this analysis indicated an implied equity value per-share reference range for Sonus of approximately $6.31 to $7.58 and an implied equity value reference range of approximately $327 million to $394 million.

The following table summarizes the GENBAND valuation ranges implied by the TEV/EBITDA multiple reference ranges applied by Evercore, based on the projections provided by the management of the GENBAND parties and adjusted projections of the GENBAND parties provided by the management of Sonus:

Selected Public Company Multiple |  | Selected Public Company Reference Range |  | Implied Valuation Range of the GENBAND parties (Management Projections) |  | Implied Valuation Range of the GENBAND parties (Adjusted Projections)
--- | --- | --- | --- | --- | --- | ---
TEV / EBITDA 2017E |  | 9.0x - 11.0x |  | $366mm - $455mm |  | $308mm - $385mm
TEV / EBITDA 2017E (with Synergies) |  | 9.0x - 11.0x |  | $876mm - $1,079mm |  | $819mm - $1,009mm

No company utilized in the peer company trading analysis is identical to Sonus or the GENBAND parties. Accordingly, an analysis of the results of the foregoing necessarily involves complex considerations and judgments concerning differences in financial, operating and market characteristics of Sonus and the GENBAND parties and other factors that could affect the public trading value of the companies to which they are being compared. In evaluating the peer companies selected, Evercore made judgments and assumptions with regard to industry performance, general business, economic,

146

Table of Contents

market and financial conditions and other matters, many of which are beyond the control of Sonus and the GENBAND parties, such as the impact of competition on Sonus and the GENBAND parties and the industry generally, industry growth and the absence of any adverse material change in the financial conditions and prospects of Sonus, the GENBAND parties, the industry or the financial markets in general. Mathematical analysis, such as determining the mean, median or average, is not in itself a meaningful method of using peer company trading data.

Implied Ownership Interest—Evercore used the resulting equity value reference ranges to calculate the implied ownership interest for Sonus for the 2017 and 2018 EBITDA multiple by dividing the highest respective equity value for the GENBAND parties, plus the average respective equity value for Sonus, less the promissory note to be paid in connection with the mergers, by the average respective equity value for Sonus for the low end of the implied Sonus ownership range in each case and dividing the lowest respective equity value for the GENBAND parties, plus the average respective equity value for Sonus, less the promissory note, by the average respective equity value for Sonus for the high end of the implied Sonus ownership range in each case. This analysis indicated implied Sonus ownership reference ranges of the shares of New Solstice's common stock issued and outstanding immediately after the closing of the transactions contemplated by the merger agreement based on the different public company multiples and summarized in the following table:

Selected Public Company Multiple |  | Selected Public Company Reference Range for GENBAND |  | Selected Public Company Reference Range for Sonus |  | Implied Sonus Ownership Reference Range
--- | --- | --- | --- | --- | --- | ---
TEV / EBITDA 2017E—Management Projections |  |  | 9.0x - 11.0x |  |  | 10.0x - 12.0x |  | 47.6% - 53.3%
TEV / EBITDA 2017E—Management Projections (with Synergies) |  |  | 9.0x - 11.0x |  |  | 10.0x - 12.0x |  | 27.1% - 31.5%
TEV / EBITDA 2018E—Management Projections |  |  | 8.0x - 10.0x |  |  | 9.0x - 11.0x |  | 46.0% - 52.3%
TEV / EBITDA 2018E—Management Projections (with Synergies) |  |  | 8.0x - 10.0x |  |  | 9.0x - 11.0x |  | 28.3% - 33.3%
TEV / EBITDA 2017E—Adjusted Projections |  |  | 9.0x - 11.0x |  |  | 10.0x - 12.0x |  | 52.0% - 57.8%
TEV / EBITDA 2017E—Adjusted Projections (with Synergies) |  |  | 9.0x - 11.0x |  |  | 10.0x - 12.0x |  | 28.4% - 33.0%
TEV / EBITDA 2018E—Adjusted Projections |  |  | 8.0x - 10.0x |  |  | 9.0x - 11.0x |  | 63.7% - 70.0%
TEV / EBITDA 2018E—Adjusted Projections (with Synergies) |  |  | 8.0x - 10.0x |  |  | 9.0x - 11.0x |  | 34.1% - 39.7%

Evercore compared these implied Sonus ownership interests to the transaction ownership split of the shares of New Solstice's common stock of approximately 50% for holders of Sonus common stock and 50% to the GENBAND parties.

Selected Precedent Transaction Analysis

Evercore performed an analysis of selected precedent transactions to compare multiples paid in other transactions to the multiples implied in the mergers. Evercore analyzed 17 merger and acquisition transactions that were announced between 2009 and 2016 involving companies in the traditional / next generation networking sectors of the technology industry, which were selected based on Evercore's professional judgment.

While none of the companies that participated in the selected precedent transactions is directly comparable to the GENBAND parties and none of the transactions in the selected precedent transactions analysis is directly comparable to the mergers, Evercore selected these transactions because each of the target companies was involved in the traditional / next generation networking sectors of the

147

Table of Contents

technology industry and had operating characteristics and products that for purposes of analysis may be considered similar to certain of the GENBAND parties' operating characteristics and products.

For each of the selected transactions, Evercore reviewed transaction values and calculated the TEV implied for each target company based on the consideration paid in the selected transaction, as a multiple of the target company's current year revenue (in each case, primarily calculated for the 12-month period prior to the latest available data on the quarter preceding the date of announcement of such transaction). In circumstances where such multiples were unavailable, last quarter annualized revenue, fourth quarter annualized revenue or Wall Street research estimates for current year revenue were utilized.

Evercore's analysis indicated mean, median, high and low TEV to current year revenue multiples of 2.54x, 1.78x, 7.87x and 0.38x, respectively. The selected precedent transactions are set forth in the table below:

Date Announced |  | Acquiror |  | Target
--- | --- | --- | --- | ---
May 23, 2016 |  | Siris Capital |  | Xura
April 04, 2016 |  | Brocade |  | Ruckus
May 04, 2015 |  | Ciena |  | Cyan
April 22, 2015 |  | Francisco Partners |  | Procera
April 21, 2015 |  | Arris |  | Pace
April 15, 2015 |  | Nokia |  | Alcatel-Lucent
March 02, 2015 |  | Mitel |  | Mavenir
December 13, 2013 |  | Sonus |  | Performance Technologies
October 21, 2013 |  | Marlin Equity |  | Tellabs
February 01, 2013 |  | Oracle |  | Acme Packet
December 19, 2012 |  | Arris |  | Motorola Home Business
June 19, 2012 |  | Sonus |  | Network Equipment Technologies
November 07, 2011 |  | Siris Capital |  | Tekelec
June 17, 2011 |  | Amdocs |  | Bridgewater
October 28, 2010 |  | Carlyle |  | Syniverse
September 16, 2010 |  | Calix |  | Occam
October 12, 2009 |  | Cisco |  | Starent

Evercore then applied a reference range of estimated revenue multiples of 2.0x to 3.0x, derived by Evercore based on its review of the selected precedent transactions and its experience and professional judgment, to the estimated revenue of the GENBAND parties, for 12 months ending March 31, 2017. This analysis indicated an implied equity value range for the GENBAND parties of $805 million to $1,225 million.

Discounted Cash Flow Analyses

The GENBAND Parties

Evercore performed a discounted cash flow analysis of the GENBAND parties to calculate the estimated present value of the standalone unlevered, after-tax free cash flows that the GENBAND parties was projected to generate from March 31, 2017 through calendar year 2021, based on financial projections of the GENBAND parties that were provided by management of GENBAND parties and adjusted financial projections of the GENBAND parties that were provided by Sonus management.

Evercore also calculated a terminal value for the GENBAND parties by applying a perpetuity growth of 2.0% to 4.0%, to the unlevered, after-tax free cash flows in the terminal year. The perpetuity growth rate was based on the professional judgment of Evercore given the nature of the GENBAND parties, their businesses, and growth rates in the global communications networking industry. The cash flows and terminal values for the GENBAND parties were then discounted to present value using a discount rate of 11.0% to 13.0%, based on an estimate of the GENBAND parties' weighted average cost of capital, were discounted to present value using a discount rate of 13%, to derive respective ranges of implied enterprise values for GENBAND. The discount rates were based on Evercore's analysis of the capital structures and costs of equity and debt of publicly traded companies that may be considered similar to the GENBAND parties. Ranges of implied equity values for the GENBAND parties were then calculated by reducing the respective ranges of implied enterprise values by the amount of the GENBAND parties' projected net debt (calculated as debt and debt-like items less cash and cash equivalents) as of March 31, 2017. Evercore performed this analysis for the GENBAND parties (a) on a standalone basis and (b) with the inclusion of Synergies estimated by management of the GENBAND parties and Sonus management to be realized from the mergers, attributing 100% of the value of such Synergies to the GENBAND parties. Evercore's analysis indicated an implied equity value reference ranges for the GENBAND parties on a standalone basis based on projections provided by management of the GENBAND parties and adjusted projections of the GENBAND parties provided by Sonus management summarized in the following table:

GENBAND Financial Projections |  | WACC |  | Perp. Growth Rate |  | Implied Equity Valuation Range of the GENBAND Parties
--- | --- | --- | --- | --- | --- | ---
Management Projections |  | 11.0% - 13.0% |  | 2.0% - 4.0% |  | $588mm - $936mm
Adjusted Projections |  | 11.0% - 13.0% |  | 2.0% - 4.0% |  | $200mm - $332mm
Management Projections (with Synergies) |  | 11.0% - 13.0% |  | 2.0% - 4.0% |  | $1,025mm - $1,595mm
Adjusted Projections (with Synergies) |  | 11.0% - 13.0% |  | 2.0% - 4.0% |  | $637mm - $992mm

Sonus

Evercore performed a discounted cash flow analysis of Sonus to calculate the estimated present value of the standalone unlevered, after-tax free cash flows that Sonus was projected to generate from March 31, 2017 through calendar year 2021, based on financial projections of Sonus that were provided by Sonus management.

Evercore also calculated a terminal value for Sonus by applying a perpetuity growth rate, in each case based on its professional judgment given the nature of Sonus and its business and industry, of 2.0% to 4.0% to the unlevered, after-tax free cash flows in the terminal year. The cash flows and the terminal values for Sonus were then discounted to present value using a discount rate of 11.0% to 13.0%, based on an estimate of Sonus' weighted average cost of capital, and NOLs (based on updated assumptions provided by Sonus management) were discounted to present value using a discount rate of 13%, to derive a range of implied enterprise values for Sonus. Range of implied equity values for Sonus were then calculated by reducing the range of implied enterprise values by the amount of Sonus' projected net debt (calculated as debt and debt-like items less cash and cash equivalents and less

149

Table of Contents

present value of NOLs) as of March 31, 2017 as provided by Sonus management. Evercore's analysis indicated an implied per-share equity value reference range for Sonus on a standalone basis of approximately $5.49 to $6.79 and an implied equity value reference range of approximately $285 million to $352 million.

Implied Ownership Interest—Based on the implied equity value reference ranges, Evercore also calculated the implied ownership interest for Sonus for the perpetuity growth rate case by dividing the highest respective equity value for the GENBAND parties, plus the average respective equity value for Sonus, less the promissory note, by the average respective equity value for Sonus for the low end of the implied Sonus ownership range in each case and dividing the lowest respective equity value for the GENBAND parties, plus the average respective equity value for Sonus, less the promissory note, by the average respective equity value for Sonus for the high end of the implied Sonus ownership range in each case. This analysis indicated implied Sonus ownership reference ranges of the shares of New Solstice's common stock issued and outstanding immediately after the closing of the transactions contemplated by the merger agreement based on financial projections of the GENBAND parties provided by management of the GENBAND parties and based on adjusted financial projections of the GENBAND parties provided by Sonus management, as summarized in the following table:

GENBAND Financial Projections |  | Implied Valuation Range of the GENBAND Parties |  | Implied Sonus Ownership Reference Range
--- | --- | --- | --- | ---
Management Projections |  | $588mm - $936mm |  | 25.9% - 36.0%
Adjusted Projections |  | $200mm - $332mm |  | 50.7% - 64.3%
Management Projections (with Synergies) |  | $1,025mm - $1,595mm |  | 16.8% - 24.1%
Adjusted Projections (with Synergies) |  | $637mm - $992mm |  | 24.7% - 34.2%

Evercore compared these implied Sonus ownership interest to the transaction ownership split of 50% for Sonus and 50% to the GENBAND parties.

Net Present Value of Future Stock Price Analysis

Evercore performed an illustrative analysis of the net present value of the future stock price of Sonus, which is designed to provide an indication of the present value of a theoretical future value of a company as a function of such company's estimated future EBITDA and its assumed TEV to NTM EBITDA multiple, as well as such company's estimated future net income net of net cash and its assumed NTM P/E multiple. Evercore used financial projections of Sonus derived from assumptions provided by Sonus management through calendar year 2018.

Evercore reviewed, among other things, TEV of the selected companies as a multiple of estimated EBITDA, as well as P/E for NTM as of March 31, 2017. Enterprise values were calculated for the purpose of this analysis as equity value (based on the per share closing price of each selected company on May 19, 2017, multiplied by the fully diluted number of such company's outstanding equity securities on such date), plus debt, plus minority interest, less cash and cash equivalents (in the case of debt, minority interest, cash and cash equivalents, as set forth on the most recently publicly available balance sheet of such company, and in the case of minority interest, where applicable). Equity values net of cash were calculated for the purpose of this analysis as equity value (based on the per share closing price of each selected company on May 19, 2017, multiplied by the fully diluted number of such company's outstanding equity securities on such date), plus debt, less cash and cash equivalents (in the case of debt, cash and cash equivalents, as set forth on the most recently publicly available balance sheet of such company). Net income net of cash was calculated as cash net income less post-tax net interest income. The financial data of the selected peer companies used by Evercore for this analysis were based on publicly available research analysts' estimates. The following table summarizes the TEV

Table of Contents

of the selected companies as a multiple of estimated EBITDA, as well as P/E, for NTM as of March 31, 2017.

|  | Traditional Networking |  | Next Generation Networking |
--- | --- | --- | --- | --- | ---
|  | NTM TEV / EBITDA |  | NTM P/E Net of Net Cash |  | NTM TEV / EBITDA |  | NTM P/E Net of Net Cash |
High |  |  | 14.6x |  |  | 23.5x |  |  | 21.8x |  |  | 35.7x |
Mean |  |  | 9.3x |  |  | 15.6x |  |  | 11.7x |  |  | 18.6x |
Median |  |  | 8.8x |  |  | 13.4x |  |  | 9.6x |  |  | 14.6x |
Low |  |  | 6.9x |  |  | 10.2x |  |  | 7.1x |  |  | 13.2x |

With the estimated EBITDA and assumed TEV to NTM EBITDA multiple, Evercore first multiplied the EBITDA estimate by a range of TEV to NTM EBITDA multiples of 9.5x to 11.5x to calculate the implied future enterprise values based on its review of the peer companies selected and its experience and professional judgment. Evercore then calculated the implied future equity values for Sonus as of December 31, 2018 by reducing the implied future enterprise values by the amount of Sonus' projected future net debt (calculated as debt and debt-like items less cash and cash equivalents and less present value of NOLs based on updated assumptions provided by Sonus management) as of December 31, 2018. Evercore then discounted the projected per-share equity value as of December 31, 2018 using a discount rate of 13.0% based on Evercore's analysis of the cost of equity for Sonus. This analysis resulted in an implied per-share equity value reference range of approximately $7.81 to $8.84 and an implied equity value reference range of approximately $405 million to $459 million.

With the estimated net income net of net cash and assumed NTM P/E multiple, Evercore first multiplied the net income net of net cash estimate by a range of NTM P/E multiples of 13.0x to 18.0x to calculate the implied future equity values net of cash based on its review of the peer companies selected and its experience and professional judgment. Evercore then calculated the implied future equity values for Sonus as of December 31, 2018 by increasing the implied future equity values net of cash by the amount of Sonus' projected future net cash (calculated as cash and cash equivalents less debt) as of December 31, 2018. Evercore then discounted the projected per-share equity value as of December 31, 2018 using the discount rate of 13.0% as determined above. This analysis resulted in an implied per-share equity value reference range of approximately $7.13 to $8.96 and an implied equity value reference range of approximately $370 million to $465 million.

Other Factors

Evercore also reviewed and considered other factors, which were not considered part of its financial analyses in connection with rendering its advice, but were referenced for informational purposes, including, among other things, the 52-week trading range and the analysts' price targets described below.

52-Week Trading Range

Evercore reviewed historical trading prices of Sonus shares during the 52-week period ended May 19, 2017, noting that the low and high closing prices during such period ranged from $5.56 to $9.72.

Analyst Price Targets

Evercore reviewed publicly available share price targets of research analysts' estimates known to Evercore as of May 19, 2017, noting that the low and high share price targets ranged from $5.00 to $10.00 (with a median price target of $7.75).

Miscellaneous

The foregoing summary of certain material financial analyses does not purport to be a complete description of the analyses or data presented by Evercore. In connection with the review of the mergers by the Sonus board, Evercore performed a variety of financial and comparative analyses for purposes of rendering its opinions. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or of the summary described above, without considering the analyses as a whole, could create an incomplete view of the processes underlying Evercore's opinions. In arriving at its fairness determinations, Evercore considered the results of all the analyses and did not draw, in isolation, conclusions from or with regard to any one analysis or factor considered by it for purposes of its opinions. Rather, Evercore made its determinations as to fairness on the basis of its experience and professional judgment after considering the results of all the analyses. In addition, Evercore may have given various analyses and factors more or less weight than other analyses and factors, and may have deemed various assumptions more or less probable than other assumptions. As a result, the ranges of valuations resulting from any particular analysis or combination of analyses described above should not be taken to be the view of Evercore with respect to the actual value of Sonus common stock or the GENBAND parties' equity value. No company used in the above analyses as a comparison is directly comparable to Sonus or the GENBAND parties, and no transaction used is directly comparable to the mergers. Further, Evercore's analyses involve complex considerations and judgments concerning financial and operating characteristics and other factors that could affect the acquisition, public trading or other values of the companies or transactions used, including judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of Sonus, the GENBAND parties and their respective advisors. Rounding may result in total sums set forth in this section not equaling 100%.

Evercore prepared these analyses for the purpose of providing opinions to the Sonus board as to the fairness to the holders of Sonus common stock, from a financial point of view, of the Sonus exchange ratio and the fairness to Sonus of the GENBAND total consideration, from a financial point of view, taking into account a significant portion of such GENBAND total consideration is in the form of New Solstice common stock. These analyses do not purport to be appraisals or to necessarily reflect the prices at which the business or securities actually may be sold. Any estimates contained in these analyses are not necessarily indicative of actual future results, which may be significantly more or less favorable than those suggested by such estimates. Accordingly, estimates used in, and the results derived from, Evercore's analyses are inherently subject to substantial uncertainty, and Evercore assumes no responsibility if future results are materially different from those forecasted in such estimates.

Pursuant to the terms of Evercore's engagement letter with Sonus, a fee of $1.5 million was payable to Evercore upon the delivery of the First Evercore Opinion to the Sonus board (regardless of the conclusion reached therein, which we refer to collectively as the Opinion Fee). No fees were payable to Evercore upon the delivery of the Second Evercore Opinion to the Sonus board. In addition, Evercore is entitled to receive a success fee upon the consummation of the mergers in an amount equal to 1.35% of the Transaction Value, defined as the value of the shares of Sonus common stock outstanding immediately prior to the consummation of the mergers (including dividends and stock repurchases made by Sonus in connection with or in anticipation of the mergers) valued at the average closing prices computed over the five trading days ending two trading days prior to the closing of the mergers. Assuming the success fee were calculated as of the date of this joint proxy statement/prospectus, based on the closing price of Sonus common stock on August 7, 2017, the success fee would be approximately $4.5 million, the payment of which would be reduced by the amount of the Opinion Fee. Sonus has also agreed to reimburse Evercore for its reasonable and documented out-of-pocket expenses and to indemnify Evercore for certain liabilities arising out of its engagement.

Prior to Evercore's engagement in connection with the mergers, Evercore and its affiliates provided financial advisory services to Sonus and received fees of approximately $1.5 million for the rendering of such services, including the reimbursement of expenses. During the two-year period prior to the delivery of each of its opinions, no material relationship existed between Evercore and its affiliates and the GENBAND parties or their respective affiliates pursuant to which compensation was received by Evercore or its affiliates as a result of such a relationship. Evercore may provide financial or other services to Sonus in the future and in connection with any such services Evercore may receive compensation.

In the ordinary course of business, Evercore or its affiliates may actively trade the securities, or related derivative securities, or financial instruments of Sonus and affiliates, for its own account and for the accounts of its customers and, accordingly, may at any time hold a long or short position in such securities or instruments.

Each issuance of the fairness opinions was approved by an Opinion Committee of Evercore.

The Sonus board engaged Evercore to act as a financial advisor based on its qualifications, experience and reputation, as well as familiarity with the business of Sonus. Evercore is an internationally recognized investment banking firm and is regularly engaged in the valuation of businesses in connection with mergers and acquisitions.

Opinion of GENBAND's Financial Advisor

GENBAND retained Guggenheim Securities to act as its financial advisor with respect to a possible business combination transaction. In selecting Guggenheim Securities as its financial advisor, GENBAND considered that, among other things, Guggenheim Securities is an internationally recognized investment banking, financial advisory and securities firm whose senior professionals have substantial experience advising companies in, among other industries, the telecommunications industry. Guggenheim Securities, as part of its investment banking, financial advisory and capital markets businesses, is regularly engaged in the valuation and financial assessment of businesses and securities in connection with mergers and acquisitions, recapitalizations, spin-offs/split-offs, restructurings, securities offerings in both the private and public capital markets and valuations for corporate and other purposes.

At the May 22, 2017 meeting of the GENBAND board, Guggenheim Securities delivered its oral opinion, which subsequently was confirmed in writing, to the effect that, as of the date of the opinion and based on the matters considered, the procedures followed, the assumptions made and various limitations of and qualifications to the review undertaken, and taking into account the Sonus merger, the merger consideration to be received by the GENBAND shareholders, GB stockholders, and GB II stockholders (which we refer to as GENBAND Merger Consideration) was fair, from a financial point of view, to the GENBAND shareholders, GB stockholders, and GB II stockholders, as a whole.

Summary of Valuation and Financial Analyses

Overview of Valuation and Financial Analyses

This "Summary of Valuation and Financial Analyses" presents a summary of the principal valuation and financial analyses performed by Guggenheim Securities and presented to the GENBAND board in connection with Guggenheim Securities' rendering of its opinion. Such presentation to the GENBAND board was supplemented by Guggenheim Securities' oral discussion, the nature and substance of which may not be fully described herein.

Some of the valuation and financial analyses summarized below include summary data and information presented in tabular format. In order to understand fully such valuation and financial analyses, the summary data and tables must be read together with the full text of the summary. Considering the summary data and tables alone could create a misleading or incomplete view of Guggenheim Securities' valuation and financial analyses.

The preparation of a fairness opinion is a complex process and involves various judgments and determinations as to the most appropriate and relevant valuation and financial analyses and the application of those methods to the particular circumstances involved. A fairness opinion therefore is not readily susceptible to partial analysis or summary description, and taking portions of the valuation and financial analyses set forth below, without considering such analyses as a whole, would in Guggenheim Securities' view create an incomplete and misleading picture of the processes underlying the valuation and financial analyses considered in rendering Guggenheim Securities' opinion.

In arriving at its opinion, Guggenheim Securities:

•
  based its valuation and financial analyses on assumptions that it deemed reasonable as they were in-line with assumptions generally made in the telecommunications industry, and which financial assumptions were in-line with assumptions generally made by financial institutions in conducting such work, including assumptions concerning general business and economic conditions, capital markets considerations and industry-specific and company-specific factors, including the impact of competition on the businesses of GENBAND, Sonus, New Solstice and the industry generally, industry growth and the absence of any adverse material change in the financial conditions and prospects of GENBAND, Sonus, New Solstice and the industry, all of which are beyond the control of GENBAND, New Solstice, Sonus and Guggenheim Securities;
•
  did not form a view or opinion as to whether any individual analysis or factor, whether positive or negative, considered in isolation, supported or failed to support its opinion;
•
  considered the results of all of its valuation and financial analyses and did not attribute any particular weight to any one analysis or factor; and
•
  ultimately arrived at its opinion based on the results of all of its valuation and financial analyses assessed as a whole and believes that the totality of the factors considered and the various valuation and financial analyses performed by Guggenheim Securities in connection with its opinion operated collectively to support its determination that, as of the date rendered and taking into account the Sonus merger, the GENBAND Merger Consideration was fair, from a financial point of view, to the GENBAND shareholders, GB stockholders, and GB II stockholders, as a whole.

With respect to the valuation and financial analyses performed by Guggenheim Securities in connection with rendering its opinion:

•
  Such valuation and financial analyses, particularly those based on estimates and projections, are not necessarily indicative of actual values or actual future results, which may be significantly more or less favorable than suggested by these analyses.
•
  None of the selected publicly traded companies used in the peer group trading valuation analyses described below is identical or directly comparable to GENBAND or Sonus; however, such companies were selected by Guggenheim Securities based on Guggenheim Securities' familiarity with the telecommunications industry in the United States because, among other reasons, they represented or involved companies that may be considered broadly similar, for purposes of Guggenheim Securities' valuation analyses, to GENBAND or Sonus.
•
  In any event, peer group trading valuation analyses are not mathematical; rather, such analyses involve complex considerations and judgments concerning the differences in business, financial, operating and capital markets-related characteristics and other factors regarding the selected publicly traded companies to which GENBAND and Sonus were compared.

At such meeting, GENBAND's management discussed that the amount of the promissory note would be reduced to $22.5 million. Guggenheim Securities reviewed this information prior to delivering its written opinion on May 23, 2017, and determined that the reduction in the amount of the promissory note was not material to its analyses in any material respect. However, the description of the analyses performed by Guggenheim Securities herein reflects the analyses as presented to the GENBAND board at its meeting on May 22, 2017.
**
  Existing Net Debt does not include accrued management fees payable by GENBAND to OEP or its affiliates, which were reflected on GENBAND's balance sheet as accrued liabilities.

Selected Peer Group Valuation Multiples (as of May 19, 2017)

Summary Statistic |  | EV/Revenue |  | EV/Gross Profit |  | EV/EBITDA |
--- | --- | --- | --- | --- | --- | --- | ---
25th Percentile |  |  | 0.95x |  |  | 1.5x |  |  | 7.2x |

75th Percentile |  |  | 2.18x |  |  | 2.7x |  |  | 12.3x |

In performing its peer group trading valuation analysis:

•

Guggenheim Securities then applied the selected reference ranges, respectively, to GENBAND senior management's estimates of Sonus' 2017 revenue, gross profit and EBITDA.
•
  Guggenheim Securities' analysis of the selected peer group companies resulted in reference ranges of Sonus' value per share of (i) $7.60-$14.60 based on 2017E revenue multiples (or $395 million—$759 million if expressed as total equity value); (ii) $8.02-$12.94 based on 2017E gross profit multiples (or $417 million -$673 million if expressed as total equity value) and (iii) $6.06—$8.16 based on 2017E EBITDA multiples (or $315 million-$424 million if expressed as total equity value).

Sonus Discounted Cash Flow Analyses. Guggenheim Securities performed stand-alone discounted cash flow analyses of Sonus based on projected after-tax unlevered free cash flows for Sonus and an estimate of its perpetual growth rate at the end of the projection horizon. In performing its illustrative discounted cash flow analyses:

•
  Guggenheim Securities based its discounted cash flow analyses on the GENBAND management financial projections for Sonus.
•
  Guggenheim Securities used a discount rate range of 11.25%-14.50% based on its estimate of Sonus' weighted average cost of capital, which Guggenheim Securities estimated based on, among other factors, (i) Guggenheim Securities' then-current estimate of the prospective US equity risk premium range, (ii) the then-prevailing yield on the 20-year US Treasury bond as a proxy for the risk-free rate, and (iii) Guggenheim Securities' investment banking and capital markets judgment and experience in valuing companies similar to Sonus.
•
  In calculating Sonus' terminal value for purposes of its discounted cash flow analyses, Guggenheim Securities used an illustrative reference range of perpetual growth rates of Sonus' terminal year normalized after-tax unlevered free cash flow of 1.50%—2.50%. The illustrative terminal values implied by the foregoing perpetual growth rate reference range were cross-checked for reasonableness by reference to Sonus' implied terminal year EBITDA multiples.
•
  Guggenheim Securities' discounted cash flow analysis resulted in an overall reference range of $6.05-$7.59 per share of Sonus common stock (or $315 million—$395 million if expressed as total equity value), as compared to the market price of $7.69 per share of Sonus common stock.
•
  Guggenheim Securities repeated the discounted cash flow analysis including the synergy estimates provided by GENBAND senior management. When the DCF value of the synergies

  Guggenheim Securities' illustrative discounted cash flow analyses resulted in an overall reference range of $505 million-$754 million for purposes of valuing GENBAND's common stock on a stand-alone intrinsic-value basis.

Implied GENBAND Ownership Analysis

In assessing the ownership split resulting from the transaction, Guggenheim Securities derived implied ownership percentages for each of Sonus and GENBAND based on the contribution to total New Solstice equity value using the valuation methodologies described in the summaries under the captions "Sonus Peer Group Trading Valuation Analyses," "Sonus Discounted Cash Flow Analyses," "GENBAND Peer Group Trading Valuation Analyses," and "GENBAND Discounted Cash Flow Analyses" set forth above. Each of these methodologies was used to generate implied total equity valuation ranges for Sonus and GENBAND which are summarized in the aforementioned sections. For each methodology, GENBAND's implied ownership split was calculated by dividing GENBAND's equity value divided by the sum of GENBAND's and Sonus' equity value, in each case as derived from the same valuation methodology.

Other Financial Reviews and Analyses

In order to provide certain context for the primary valuation and financial analyses in connection with its opinion as described above, Guggenheim Securities performed various additional financial reviews and analyses as summarized below solely for reference purposes. As a general matter, Guggenheim Securities does not consider such additional financial reviews and analyses to be determinative valuation methodologies for purposes of its opinion.

Leverage-Adjusted Relative Contribution Analysis. Guggenheim Securities calculated implied ownership splits based on the relative contribution of each of GENBAND and Sonus to the combined company's revenue, gross profit and EBITDA. In order to facilitate the comparability of such enterprise-related contribution percentages with the merger-related equity ownership splits, Guggenheim Securities calculated the equity value implied by Sonus' market enterprise value with respect to the relevant metric and then calculated the contribution of each company to the combined company's pro forma equity value excluding synergies.

GENBAND Illustrative Has/Gets Analysis (Based on DCF). Guggenheim Securities analyzed the illustrative pro forma impact of the transaction on GENBAND's discounted cash flow valuation based

164

Table of Contents

on (i) the financial projections for each of GENBAND and Sonus and the synergy estimates, in each case provided by GENBAND management and (ii) the GENBAND Merger Consideration. Guggenheim Securities noted that GENBAND's DCF value per share without synergy estimates and after giving effect to the transaction would decrease between 1.5% and 10.3%. When synergies are included, GENBAND's DCF value per share would increase 14.4% on the low end and 23.4% on the high end.

GENBAND Illustrative Has/Gets Analysis (Based on Market Approach). Guggenheim Securities analyzed the pro forma impact of the transaction on the Sonus stock price and the implied GENBAND attributable equity value assuming that the value of the combined company would be equal to (i) the market value of Sonus, plus (ii) the value of GENBAND implied by the 50% ownership split (i.e. equal to the market value of Sonus), plus (iii) the capitalized value of synergies assuming an 8x capitalization multiple, less (iv) typical adjustments from equity value to enterprise value including debt, cash, the PV of NOLs. Under those assumptions, the Sonus stock price would be $12.01 per share as compared to the then current price of $7.69, and the total equity value attributable to legacy GENBAND shareholders would be $649 million.

Other Considerations

GENBAND did not provide specific instructions to, or place any limitations on, Guggenheim Securities with respect to the procedures to be followed or factors to be considered in performing its valuation and financial analyses or providing its opinion. The type and amount of consideration payable in the transaction were determined through negotiations between GENBAND and Sonus and were approved by the GENBAND board. The decision to enter into the merger agreement was solely that of the GENBAND board. Guggenheim Securities' opinion was just one of the many factors taken into consideration by the GENBAND board. Consequently, Guggenheim Securities' valuation and financial analyses should not be viewed as determinative of the decision of the GENBAND board with respect to the fairness, from a financial point of view, of the GENBAND Merger Consideration to the holders of GENBAND shares, GB stock, and GB II stock, as a whole, taking into account the Sonus merger.

Pursuant to the terms of Guggenheim Securities' engagement letter, GENBAND has agreed to pay Guggenheim Securities a cash transaction fee of $2.25 million, of which $1.00 million was payable upon Guggenheim Securities rendering its fairness opinion and $1.25 million is contingent on successful consummation of the transaction. In addition, GENBAND has agreed to reimburse Guggenheim Securities for certain expenses and to indemnify it against certain liabilities arising out of its engagement.

Guggenheim Securities has not otherwise been engaged during the past two years by GENBAND or Sonus to provide financial advisory or investment banking services. Guggenheim Securities may seek to provide GENBAND, New Solstice, Sonus and their respective affiliates with certain financial advisory and investment banking services unrelated to the transaction in the future.

Guggenheim Securities and its affiliates and related entities engage in a wide range of financial services activities for its and their own accounts and the accounts of its and their customers, including: asset, investment and wealth management; insurance services; investment banking, corporate finance, transaction and acquisitions and restructuring; merchant banking; fixed income and equity sales, trading and research; and derivatives, foreign exchange and futures. In the ordinary course of these activities, Guggenheim Securities or its affiliates and related entities may (i) provide such financial services to GENBAND, New Solstice, Sonus, other participants in the transaction or their respective affiliates, subsidiaries, investment funds and portfolio companies, for which services Guggenheim Securities or its affiliates and related entities have received, and may receive, compensation and (ii) directly or indirectly, hold long or short positions, trade and otherwise conduct such activities in or with respect to certain bank debt, debt or equity securities and derivative products of or relating to GENBAND,

Sonus, other participants in the transaction or their respective affiliates, subsidiaries, investment funds and portfolio companies. Furthermore, Guggenheim Securities or its affiliates and related entities and its or their directors, officers, employees, consultants and agents may have investments in GENBAND, Sonus, other participants in the transaction or their respective affiliates, subsidiaries, investment funds and portfolio companies.

Consistent with applicable legal and regulatory guidelines, Guggenheim Securities has adopted certain policies and procedures to establish and maintain the independence of its research departments and personnel. As a result, Guggenheim Securities' research analysts may hold views, make statements or investment recommendations and publish research reports with respect to GENBAND, New Solstice, Sonus, other participants in the transaction or their respective affiliates, subsidiaries, investment funds and portfolio companies and the transaction that differ from the views of Guggenheim Securities' investment banking personnel.

Reasons of GENBAND, GB and GB II for the Transactions

In considering the reasons of GENBAND, GB and GB II (each of which we refer to individually as a GENBAND party and, collectively, as the GENBAND parties) for the transactions contemplated by the merger agreement, you should be aware that each GENBAND party's respective directors may have interests in the transactions contemplated by the merger agreement that may be different from, or in addition to, the interests of such GENBAND party's shareholders or stockholders (as applicable) generally. These interests are described in the section entitled "The Mergers—Interests of Directors and Executive Officers in the Transactions—Interests of Directors and Executive Officers of the GENBAND Parties in the Transactions" beginning on page 177 of this joint proxy statement/prospectus.

In the course of reaching their decision, the members of the board of directors of each GENBAND party consulted with such GENBAND party's management and legal and financial advisors, reviewed a significant amount of information and considered a number of factors, both positive and negative, and potential benefits and detriments of each merger to such GENBAND party and such GENBAND party's shareholders or stockholders (as applicable). The board of directors of each GENBAND party additionally considered potential strategic alternatives for such GENBAND party, including reviewing potential business combination partners, on an ongoing basis. The board of directors of each GENBAND party believed that, taken as a whole, the following factors supported its decision to approve the transactions contemplated by the merger agreement:

•
  the belief that, based on the assessment by the board of directors of such GENBAND party of the value of such GENBAND party as an independent company, the value implied by the merger consideration to be received by such GENBAND party's shareholders or stockholders (as applicable) is attractive;
•
  the belief that the transactions contemplated by the merger agreement gives stockholders of GB and GB II the best chance to realize any value from their shares in GB and GB II, respectively;
•
  the future prospects if such GENBAND party were to remain independent as compared to the prospects of the combined company, given the competitive landscape and the business, financial, execution and other risks associated with continued independence, as well as current industry, economic and market conditions and trends;
•
  the strategic benefits of the proposed transaction with Sonus that the board of directors of such GENBAND party believed could result from, among other factors, the complementary nature of GENBAND's and Sonus' businesses and the anticipated cost synergies, as further described in the section entitled "The Mergers—Certain Prospective Financial Information of Sonus and

167

Table of Contents

GENBAND—Estimated Cost Synergies" beginning on page 132 of this joint proxy statement/prospectus";

•
  the results of the due diligence investigation that such GENBAND party's management conducted with the assistance of its advisors on Sonus with respect to certain matters, including Sonus' historical financial condition, results of operations, business and prospects of Sonus, and the business reputation and capabilities of Sonus and its management;
•
  the opportunity for shareholders or stockholders (as applicable) of such GENBAND party to be able to participate in the future growth of the combined company and hold shares of a publicly traded company;
•
  the fact that the combined company will benefit from a diversified and balanced portfolio across the telecommunications industry and, due to its expected size and scale, from a broader services offering;
•
  the belief that the transactions contemplated by the merger agreement are more favorable to such GENBAND party's shareholders than other strategic alternatives that the GENBAND parties explored, including, among other things, potential mergers and other strategic transactions with public and private counterparties, potential debt or equity financings and continued operations as independent privately held companies, and, in light of the considerations around other potential partners, the belief of the board of directors of such GENBAND party that Sonus was the best strategic partner for GENBAND given the complementary nature of its business and the belief that the transactions contemplated by the merger agreement would create greater long-term value for shareholders of GENBAND, GB and GB II, taking into account the consideration to be received in connection with, and the likelihood of consummating, such transactions, as well as business, competitive, industry and market risks;
•
  the oral opinion, delivered by Guggenheim Securities to GENBAND's board of directors as to the fairness, from a financial point of view and as of the date of the opinion, of the merger consideration to be received by the GENBAND shareholders, GB stockholders and GB II stockholders, as a whole, taking into account the Sonus merger, which opinion was based on and subject to the matters considered, the procedures followed, the assumptions made and various limitations and qualifications to the review undertaken as more fully described under the section entitled "Opinion of GENBAND's Financial Advisor" above;
•
  the likelihood that the transactions contemplated by the merger agreement will be consummated on a timely basis in light of, among other things, the conditions to the merger and the likelihood of the transactions receiving all necessary approvals;
•
  the parties' expectation and intention that, for U.S. federal income tax purposes, the exchange of GENBAND shares for New Solstice common stock pursuant to the GENBAND merger, taken together with the other mergers, will qualify as a transfer of property to New Solstice described in Section 351 of the Code;
•
  the belief that the terms of the merger agreement and the other transaction documents, taken as a whole, provide a significant degree of certainty that the transaction will be completed, including the facts that (i) the merger agreement provides for a termination fee of $14.5 million payable to GENBAND in certain circumstances, as more fully described in the section entitled "The Merger Agreement—Termination Fee" beginning on page 211 of this joint proxy statement/prospectus, (ii) the merger agreement requires the GENBAND parties and Sonus, New Solstice, Solstice Merger Sub, Cayman Merger Sub and GB Merger Sub (which we refer to collectively as the Sonus parties) to use reasonable best efforts to obtain the required consents from governmental entities, including by agreeing to any material divestitures, licenses, separate arrangements or similar matters, including material covenants affecting business operating

168

Table of Contents

practices, except to the extent any such divestitures, licenses, arrangements, matters or covenants would reasonably be expected to be material to the GENBAND parties and Sonus, taken as a whole, as more fully described in the section entitled "The Merger Agreement—Conditions to the Mergers" beginning on page 207 of this joint proxy statement/prospectus, and (iii) there are limited circumstances in which Sonus may terminate the merger agreement, as more fully described in the section entitled "The Merger Agreement—Termination" beginning on page 210 of this joint proxy statement/prospectus;

•
  the determination that the terms of the merger agreement (including the parties' representations, warranties and covenants and the conditions to their respective obligations) are reasonable under the circumstances;
•
  that, as a result of the mergers, GENBAND's shareholders would have greater liquidity options through its receipt of shares of publicly traded New Solstice common stock and cash in exchange for their GENBAND shares, which shares are not publicly traded;
•
  the likelihood that the resources of the combined companies will provide GENBAND a platform to expand its business to new customers, network solutions and markets;
•
  the parties' interest to work with one another's management to develop new services and solutions to further develop GENBAND's platform and business;
•
  the board's assessment of the business, earnings, operations, financial condition, asset, quality, capital levels, strength and leadership of the management and prospects of both Sonus and GENBAND; and
•
  that New Solstice will be better able to grow, gain market share and serve GENBAND's customer base than GENBAND can alone.

In the course of reaching their decision, the members of the board of directors of each GENBAND party also considered a number of risks and potentially negative factors concerning the transactions contemplated by the merger agreement, including, among others, the following:

•
  the risk that certain shareholders or stockholders (as applicable) of the GENBAND parties may not receive consideration pursuant to the merger agreement and transactions contemplated therein as a result of the value of the Sonus common stock prior to the GENBAND mergers and the operation of the liquidation waterfall of Article 5.2 of the GENBAND Articles of Association attached as Annex C to this joint proxy statement/prospectus;
•
  the fact that there can be no assurance that all conditions to the parties' obligations to consummate the transactions contemplated by the merger agreement will be satisfied and, as a result, the transactions contemplated by the merger agreement might be delayed or not be completed, including due to a failure to obtain the required shareholder or stockholder approvals (as applicable) in accordance with the terms agreed upon by the parties, or due to a failure of other closing conditions, and the resulting risks to the GENBAND parties and their respective stockholders or shareholders (including with respect to the diversion of management and employee attention, potential employee attrition and potential adverse effects on GENBAND's customer or other commercial relationships following the announcement of a transaction);
•
  the restrictions on GENBAND's business during the pendency of the transactions contemplated by the merger agreement (which may delay or prevent the GENBAND parties from undertaking certain opportunities that may arise during such time);
•
  the possibility that the transactions might not be consummated, including as a result of the ability of Sonus, under certain circumstances, to change its recommendation that its stockholders

169

Table of Contents

vote in favor of the approval of the Sonus merger and the adoption of the merger agreement in response to certain acquisition proposals and certain intervening events and, subject to certain specified conditions, to terminate the merger agreement to accept a superior acquisition proposal, and, if the transactions are not consummated, the materially adverse impact such event could have on GENBAND's financial condition, results of operations and business;

•
  the restrictions on the GENBAND parties' ability to solicit, negotiate, or provide information with respect to, any alternative transaction proposal, which the members of each GENBAND party's board understood was a condition to the Sonus parties' willingness to enter into a transaction, which each GENBAND party's board believed could have the effect (in combination with the voting agreement) of discouraging third parties from submitting alternative proposals for a business combination with the GENBAND parties, but which the board of each GENBAND party determined was fair and reasonable to each of the GENBAND parties and their respective shareholders or stockholders (as applicable) in light of (among other things) the benefits of the transactions contemplated by the merger agreement to each GENBAND party's shareholders or stockholders (as applicable);
•
  the risks that the financial results or stock price of the combined company might decline, including the possible adverse effects on the stock price and financial results of the combined company if any expected benefits or synergies are not obtained on a timely basis or at all;
•
  the additional risks, management's time and expenses to be incurred in connection with the mergers and other transactions contemplated by the merger agreement;
•
  the risk that the combined company may not be able to successfully integrate the businesses, personnel and operations of the GENBAND parties and Sonus and, as a result, may not be able to realize the potential benefits and anticipated cost synergies;
•
  the fact that some of the GENBAND parties' respective directors and executive officers, in evaluating and negotiating the merger agreement, the transactions contemplated thereby and in recommending to such GENBAND party's shareholders or stockholders (as applicable) that the merger agreement be adopted and the transactions contemplated thereby be approved, may have interests in the transactions contemplated by the merger agreement that may be different from, or in addition to, those of the GENBAND parties' respective shareholders or stockholders (as applicable) generally, including as a result of employment and compensation arrangements and the manner in which they could be affected by the transactions contemplated by the merger agreement;
•
  the fact that the merger consideration does not include a cash component (other than cash received in lieu of fractional shares) to allow the shareholders or stockholders (as applicable) of each GENBAND party to achieve some immediate liquidity with respect to their investment in such GENBAND party;
•
  the fact that, in the stockholders agreement, certain shareholders or stockholders (as applicable) of the respective GENBAND parties will agree generally not to transfer any of their shares of New Solstice common stock for a specified period following completion of the transactions contemplated by the merger agreement;
•
  other risks and uncertainties as described in the sections entitled "Risk Factors" and "Cautionary Statement Regarding Forward-Looking Statements" beginning on pages 57 and 55, respectively, of this joint proxy statement/prospectus;
•
  the risks of dissatisfied management associated with new board members and new shareholders;
•
  the possible disruption of GENBAND's business that may result from the announcement of the transaction;

170

Table of Contents

•
  the risk that Sonus does not meet its internal projections as disclosed in the section entitled "The Mergers—Certain Prospective Financial Information of Sonus and GENBAND" beginning on page 128 of this joint proxy statement/prospectus;
•
  the substantial costs to be incurred in connection with the transaction, including the costs of integrating the businesses of Sonus and GENBAND and the transaction expenses arising from the mergers; and
•
  the potential risk of diverting management focus and resources from operational matters and other strategic opportunities while working to implement the mergers.

While the members of the board of directors of each GENBAND party considered potentially positive and potentially negative factors, they concluded that, overall, the potentially positive factors outweighed the potentially negative factors. Accordingly, the board of directors of each GENBAND party determined that the mergers, the terms thereof and the other transactions contemplated by the merger agreement are advisable and in the best interests of each GENBAND party and its shareholders or stockholders (as applicable) and recommended that such shareholders or stockholders (as applicable) adopt the merger agreement and approve the transactions contemplated thereby.

The foregoing discussion is not intended to be an exhaustive list of the information and factors considered by the members of the board of each GENBAND party in their consideration of the merger agreement and the transactions contemplated thereby, but is merely a summary of the material positive factors and material negative factors considered by the members of the board of each GENBAND party in that regard. In view of the number and variety of factors and the amount of information considered, the members of the board of each GENBAND party did not find it practicable to, and did not make specific assessments of, quantify, or otherwise assign relative weights to, the specific factors considered in reaching its determination. In addition, members of the board of each GENBAND party did not undertake to make any specific determination as to whether any particular factor, or any aspect of any particular factor, was favorable or unfavorable to its ultimate determination, and individual members of the board of each GENBAND party may have given different weights to different factors. Based on the totality of the information presented, the members of the board of each GENBAND party reached the decision to adopt the merger agreement and approve the mergers and the other transactions contemplated by the merger agreement in light of the factors described above and other factors that the members of the board of each GENBAND party felt were appropriate.

This explanation of the GENBAND parties' reasons for the transactions contemplated by the merger agreement and other information presented in this section contains statements that are forward-looking in nature and, therefore, should be read in light of the section entitled "Cautionary Statement Regarding Forward-Looking Statements" beginning on page 55 of this joint proxy statement/prospectus.

Interests of Directors and Executive Officers in the Transactions

Interests of Directors and Executive Officers of Sonus in the Transactions

In considering the recommendation of the Sonus board that Sonus stockholders vote to approve the Sonus merger and adopt the merger agreement, Sonus stockholders should be aware that members of the Sonus board and Sonus' executive officers have interests in the Sonus merger, and the other transactions contemplated by the merger agreement, that may be different from, or in addition to, or may conflict with, the interests of Sonus' stockholders generally. The Sonus board was aware of these potentially different or conflicting interests and considered them, among other matters, in reaching its decision to adopt the merger agreement and approve the transactions contemplated thereby, including the Sonus merger, and to recommend that Sonus stockholders vote in favor of the Sonus merger proposal.

Continuing Services as Directors on the New Solstice Board

The New Solstice board after the consummation of the mergers will include four of the directors from the Sonus board immediately prior to the consummation of the mergers. The Sonus board presently consists of seven directors, including Sonus' President and Chief Executive Officer. While the specific compensation program for the remainder of 2017 and 2018 for New Solstice has not been determined, it is currently expected that the compensation for non-employee directors of New Solstice will be similar to the compensation program for Sonus non-employee directors immediately prior to the effective time of the mergers. For a discussion of the New Solstice board, see the sections entitled "The Merger Agreement—Directors and Officers of New Solstice after the Mergers" and "Management and Other Information of the Combined Company" beginning on pages 193 and 250, respectively, of this joint proxy statement/prospectus.

Stock Options and Other Stock-Based Awards

As a result of the Sonus merger, the vesting of certain unvested equity awards and equity-based awards (which currently include stock options, restricted stock, restricted stock units and performance share units) will be accelerated. For a discussion of the treatment of Sonus stock options and other equity awards, see the section entitled "The Merger Agreement—Treatment of Sonus Equity Awards" beginning on page 193 of this joint proxy statement/prospectus.

Based upon equity compensation holdings as of August 7, 2017, the directors and other executive officers of Sonus held the following unvested Sonus options, restricted stock awards, restricted stock units and performance share units:

Severance Arrangements with Sonus Named Executive Officers

Sonus has entered into severance arrangements with each of its "named executive officers." The severance arrangements generally provide that, upon an involuntary termination of the named executive officer by Sonus without cause (as defined in the named executive officer's employment agreement), or (except in the case of Ms. Villare) upon a resignation by the named executive officer for good reason (as defined in the named executive officer's employment agreement), the named executive officer is entitled to severance benefits as follows:

•
  For Mr. Dolan, severance payments equal to 150% of his base salary and target cash bonus, continued health plan premium payments for up to 18 months, and 24 months accelerated vesting of all unvested restricted stock, stock options and performance shares;
•
  For Mr. Snider, severance payments equal to 100% of his base salary and target cash bonus, continued health plan premium payments for up to 12 months, 12 months accelerated vesting of all unvested stock options and full vesting of all unvested restricted stock; and
•
  For other named executive officers, severance payments equal to 100% of his or her base salary and target cash bonus, continued health plan premium payments for up to 12 months, and 12 months accelerated vesting of all unvested restricted stock and stock options.

The severance arrangements also generally provide that, upon an involuntary termination of the named executive officer by Sonus without cause in connection with a change in control (which would include the Sonus merger), or (except in the case of Ms. Villare) upon a resignation by the named executive officer for good reason in connection with a change in control (which would include the Sonus merger), the named executive officer is entitled to severance benefits as follows:

•
  For Mr. Dolan, severance payments equal to 200% of his base salary and target cash bonus, continued health plan premium payments for up to 18 months, and full vesting of all unvested restricted stock, stock options and performance shares;

  For Ms. Villare, severance payments equal to 100% of her base salary and target cash bonus, continued health plan premium payments for up to 12 months, and 12 months accelerated vesting of all unvested restricted stock and stock options;
•
  For Mr. Snider, severance payments equal to 150% of his base salary and target cash bonus, continued health plan premium payments for up to 18 months, 12 months accelerated vesting of unvested stock options and full vesting of all unvested restricted stock; and
•
  For other named executive officers, severance payments equal to 150% of his base salary and target cash bonus, continued health plan premium payments for up to 18 months, and full vesting of all unvested restricted stock and stock options.

None of the Sonus severance arrangements provide for tax gross-ups in connection with severance benefits following a change in control. The Compensation Committee of Sonus believes that these provisions are consistent with executive severance arrangements that are customary for public companies at the stage of development of Sonus and were necessary in order to hire and/or retain the executives.

Continuing Employment with New Solstice

Under the merger agreement, upon completion of the mergers, the officers of Sonus immediately before the effective time of the Sonus merger will be officers of New Solstice. In addition, Raymond Dolan, Sonus' President and Chief Executive Officer, will serve as President and Chief Executive Officer of New Solstice. While the specific compensation program at New Solstice for the remainder of 2017 and for 2018 has not been determined, it is currently expected that the named executive officers

of Sonus will continue their employment with New Solstice following the mergers on similar terms and conditions as those terms and conditions in existence immediately prior to the mergers.

Quantification of Potential Payments to Sonus Named Executive Officers in Connection with the Mergers

Set forth below is information about the compensation for each Sonus "named executive officer" that is based on or otherwise relates to the mergers. Sonus' named executive officers for purposes of the disclosure in this section of this joint proxy statement/prospectus are the following individuals:

•
  Raymond Dolan, President and Chief Executive Officer;
•
  Susan Villare, Interim Chief Financial Officer, Treasurer and Vice President, Financial Planning and Analysis;
•
  Kevin Riley, Senior Vice President, Engineering and Chief Technology Officer;
•
  Jeffrey Snider, Senior Vice President, Chief Administrative Officer, General Counsel and Corporate Secretary; and
•
  Michael Swade, Senior Vice President, Worldwide Sales.

In accordance with Item 402(t) of Regulation S-K, the table below sets forth the compensation that is based on or otherwise relates to the mergers that may become payable to each of Sonus' named executive officers (which we refer to as golden parachute compensation). See the sections entitled "—Interests of Directors and Executive Officers of Sonus in the Transactions—Stock Options and Other Stock-Based Awards" and "—Interests of Directors and Executive Officers of Sonus in the Transactions—Severance Arrangements with Sonus Named Executive Officers" beginning on pages 172 and 173, respectively.

The amounts set forth below represent an estimate of each named executive officer's golden parachute compensation, assuming the following:

•
  that consummation of the Sonus merger constitutes a change in control or acquisition for purposes of the applicable compensation plan, arrangement or agreement;
•
  that the Sonus merger was consummated on August 7, 2017;
•
  each named executive officer's employment is terminated by Sonus (or any successor entity following a change in control) without "cause" or by the named executive officer with "good reason" immediately following the Sonus merger; and
•
  the value of the vesting acceleration of the named executive officers' equity awards is calculated assuming a price per share of Sonus common stock of $7.06 (the average closing market price of a share of Sonus common stock on NASDAQ over the first five business days following the first public announcement of the merger agreement).

The following table, footnotes and discussion describe single and double trigger benefits for the named executive officers. For purposes of this discussion, "single trigger" refers to benefits that arise solely from the closing of the mergers and "double trigger" refers to benefits that require two conditions, namely, the closing of the mergers and a qualifying termination in connection with the closing of the mergers. The amounts reported below are estimated based on multiple assumptions that may or may not actually occur, including the assumptions described above, and elsewhere in this joint proxy statement/prospectus. As a result, the golden parachute compensation, if any, to be received by a named executive officer may materially differ from the amounts set forth below.

(1)
  The amounts in this column represent "double trigger" severance benefits payable by Sonus upon or after a change in control to Sonus' named executive officers pursuant to severance arrangements with each of Sonus' named executive officers. Such amounts represent severance payments equal to 150% of his or her annual base salary and target bonus (or 100% for Ms. Villare and 200% for Mr. Dolan). Severance payments to the named executive officers other than Ms. Villare would be payable in a lump sum payment at the time of termination. Severance payments to Ms. Villare attributable to her base salary would be payable in accordance with Sonus' usual payroll practices for a period of 12 months following the termination date, and severance payments to Ms. Villare attributable to her target cash bonus would be payable at the same time and in the same form as her target bonus would otherwise have been paid. There are no tax gross-ups on any severance benefits payable to Sonus' named executive officers. The receipt of severance benefits is contingent upon the execution of a release of all claims of any kind or nature in favor of Sonus, and, for Ms. Villare, Mr. Riley and Mr. Swade, compliance with restrictive covenants relating to non-competition and non-solicitation.
(2)
  The amounts in this column represent the value attributable to "single trigger" or "double trigger" accelerated vesting of Sonus equity and equity-based awards as set forth below.

Stock Options. Amounts attributable to Sonus stock options represent the value of the "single trigger" accelerated vesting of in-the-money stock options, which will become vested in full as of five business days prior to the closing date of the Sonus merger. Based on the assumed stock price ($7.06), none of the stock options held by the named executive officers will be in-the-money.

Restricted Stock Awards; Restricted Stock Units; Performance Share Units. Amounts attributable to Sonus restricted stock awards, restricted stock units and performance share units for all named executive officers represent the aggregate value of the accelerated vesting of certain outstanding restricted stock awards, restricted stock units and performance share units that would vest immediately (in the case of performance share units, at 100% of the target rate) prior to the effective time of the mergers (referred to as "single trigger") and the aggregate value of the accelerated vesting of restricted stock awards, restricted stock units and performance share units that would vest (in the case of

(a)
  Amounts set forth in this column reflect the aggregate value of the applicable awards that would vest applying a "double trigger" pursuant to which the executive is terminated in connection with the mergers. If the executive is not terminated, he or she will only be entitled to the amounts set forth in the "single trigger" column.

(3)
  The amounts reflect "double trigger" benefits that would be payable upon a qualifying termination following the closing of the mergers and represent continued medical and welfare benefits for each named executive officer and his or her family, for 12 months, in the case of Ms. Villare, and for 18 months, in the case of each of the other named executive officers. None of the named executive officers are eligible for perquisites, outplacement services or retiree medical benefits. Receipt of these benefits is conditioned upon the named executive officer's execution of a general release, and, for Ms. Villare, Mr. Riley and Mr. Swade, compliance with restrictive covenants relating to non-competition and non-solicitation.
(4)
  On the week of the signing of the merger agreement by Sonus, the Compensation Committee approved the following one-time and retention bonus payments, payable conditioned upon the named executive officer remaining employed by Sonus upon the date of each event set forth in the table below triggering the bonus payment obligation, or upon termination if such named executive officer's termination was by Sonus without cause or by the named executive officer for good reason:

Indemnification Arrangements

Under the merger agreement, New Solstice will indemnify, hold harmless and advance expenses to, among others, all past and present directors and officers of Sonus and its respective subsidiaries (in all of their capacities) (i) to the same extent such persons are indemnified or have the right to

176

Table of Contents

advancement of expenses prior to the date of the merger agreement by Sonus and (ii) to the fullest extent permitted by law, in each case for acts or omissions in their capacities as directors or officers occurring at or prior to the effective time. New Solstice will also include and cause to be maintained in effect in Sonus' certificate of incorporation and by-laws, or equivalent organizational documents, after the effective time provisions regarding elimination of liability of directors, indemnification of officers and directors, and advancement of expenses which are, in the aggregate, no less advantageous to the intended beneficiaries than the corresponding provisions contained in Sonus' certificate of incorporation and by-laws, or equivalent organizational documents, and periodically advance to any such indemnitee its legal and other expenses (including the cost of any investigation and preparation incurred in connection therewith). New Solstice will cause to be maintained for a period of six years after the effective time the current policy of directors' and officers' liability insurance and fiduciary liability insurance maintained by Sonus with respect to claims arising from facts or events that occurred on or before the effective time. See the section entitled "The Merger Agreement—Additional Agreements—Indemnification, Exculpation and Insurance" beginning on page 205 of this joint proxy statement/prospectus.

In addition, Sonus has entered into indemnification agreements with its executive officers and directors.

Interests of Directors and Executive Officers of the GENBAND Parties in the Transactions

In considering the recommendation of the GENBAND, GB and GB II boards that GENBAND shareholders, GB stockholders and GB II stockholders, respectively, adopt the merger agreement and approve the transactions contemplated thereby, GENBAND shareholders, GB stockholders and GB II stockholders should be aware that members of the GENBAND, GB and GB II boards and the executive officers of GENBAND, GB and GB II have interests in the transactions contemplated by the merger agreement that may be different from, or in addition to, or may conflict with, the interests of GENBAND shareholders, GB stockholders and GB II stockholders generally. These interests relate to or arise from, among other things, the following events and circumstances:

•
  The accelerated vesting and/or payment in respect of GENBAND Class E Shares held by certain executive officers and directors of GENBAND, GB and GB II;
•
  The grant of New Solstice equity to certain executive officers and directors of GENBAND, GB and GB II who currently hold GENBAND Class E Shares;
•
  The employment, severance and consulting agreements with the executive officers and directors of GENBAND, GB and GB II that provide severance compensation in connection with certain terminations of service;
•
  The retention and similar bonuses that certain executive officers and directors of GENBAND, GB and GB II are eligible to receive if the mergers are consummated;
•
  Certain existing executive officers of GENBAND, GB and GB II, including Daryl E. Raiford, are expected to continue to be employed as New Solstice executive officers following consummation of the mergers. The composition of the New Solstice executive officer team has not yet been finalized;
•
  Certain existing directors of GENBAND, GB and GB II are expected to continue to be engaged as New Solstice directors following consummation of the mergers. The composition of the New Solstice board has not yet been finalized;
•
  The right to continued indemnification for directors and executive officers of GENBAND and GB following the completion of the mergers and the other transactions contemplated by the merger agreement, pursuant to the terms of the merger agreement and indemnification

177

Table of Contents

agreements entered into by certain directors and officers of the GENBAND parties, as described in more detail below;

•
  Certain executive officers and directors may enter into agreements with one or more of the GENBAND parties pursuant to which (i) such executive officers and directors waive their rights to certain payments and benefits subject to receipt of shareholder approval of such payments in accordance with Section 280G and (ii) the GENBAND parties may agree to seek such shareholder approval for purposes of Section 280G. No such agreements have been entered into to date and the GENBAND parties have no obligation to obtain shareholder approval for purposes of Section 280G and receipt of such shareholder approval is not a condition to the consummation of the mergers; and
•
  The affiliation of certain directors and officers of the GENBAND parties with OEP and its affiliates. As further described in the section titled "Related Person Transactions" beginning on page 339 of this joint proxy statement/prospectus, GENBAND is party to a Subordinated Term Loan with an affiliate of OEP, under which all outstanding amounts are expected to be paid off in connection with the mergers. GENBAND is also party to a management fee agreement with OEP, which will be terminated in connection with the closing. All management fees payable to OEP (approximately $10 million) are expected to be paid off prior to the consummation of the mergers. In addition, the merger agreement contemplates, as a condition to the closing of the transactions contemplated thereby, that at the closing, New Solstice will enter into a stockholders agreement with the OEP Stockholders.

The GENBAND, GB and GB II boards were aware of these potential differing interests and considered them, among other matters, in reaching its decision to adopt the merger agreement and approve the transactions contemplated thereby, including the GENBAND, GB and GB II mergers, and to recommend that GENBAND shareholders, GB stockholders and GB II stockholders adopt the merger agreement and approve the transactions contemplated thereby. Other than full disclosure of these potential conflicts of interest, the GENBAND, GB and GB II boards did not take any other steps to alleviate such potential conflicts of interest since it did not consider such potential conflicts of interest to be material in connection with its decision to adopt the merger agreement and approve the transactions contemplated thereby, including the GENBAND, GB and GB II mergers.

As of the close of business on the GENBAND record date, directors and executive officers of GENBAND owned and were entitled to vote, in the aggregate, [ ] GENBAND shares entitled to vote at the Extraordinary General Meeting, which represent [ ] percent ([ ]%) of the aggregate voting power of the outstanding GENBAND shares on that date. As of the close of business on the GB record date, directors and executive officers of GB owned and were entitled to vote, in the aggregate, [ ] shares of common stock, which represent [ ] percent ([ ]%) of the aggregate voting power of the outstanding GB common stock on that date. As of the close of business on the GB II record date, directors and executive officers of GB II did not own any shares of GB II common stock.

Equity-Based Compensation

Under GENBAND's Amended and Restated Equity Incentive Plan, GENBAND's directors and executive officers have previously been granted profits interests in GENBAND in the form of GENBAND Class B Shares, all of which are currently vested. In addition, under the GENBAND 2013 Equity Incentive Plan, GENBAND's directors and executive officers have previously been granted profits interests in GENBAND in the form of GENBAND Class E Shares, which vest over four years following grant, subject to continued employment. The vesting of all GENBAND Class E Shares is expected to accelerate in connection with the mergers.

In connection with the GENBAND merger, all outstanding GENBAND shares, including the GENBAND Class B Shares and Class E Shares, will be converted into shares of New Solstice common

178

Table of Contents

stock and a portion of the promissory note as further described in the section entitled "Other Related Agreements—The Promissory Note" beginning on page 217 of this joint proxy statement/prospectus. The number of shares of New Solstice common stock and the portion of the promissory note received in respect of each GENBAND Class B Share and GENBAND Class E Share will be determined based on the value of such consideration at the time of the mergers. It is not expected, however, that any consideration will be received in respect of the GENBAND Class B Shares. Further, consideration will be received in respect of GENBAND Class E Shares only to the extent the fair value of GENBAND exceeds the applicable threshold value for such GENBAND Class E Shares, which in all cases equals or exceeds $478 million.

The table below sets forth, as of August 7, 2017, information with respect to the GENBAND Class B Shares and GENBAND Class E Shares held by each of GENBAND's executive officers and directors and the estimated number of shares of New Solstice common stock to be received in respect of such equity interests assuming the fair value of GENBAND equals $380.4 million, the estimated value of the shares of New Solstice common stock (based on an assumed value of each share of New Solstice common stock equal to $6.91, Sonus' closing price per share as of August 7, 2017) and promissory note received by GENBAND shareholders in connection with the GENBAND merger), in addition to any portion of the promissory note:

Under the GB Amended and Restated 1999 Stock Option/Stock Issuance Plan (which we refer to as the 1999 Plan), certain GB directors have previously been granted GB Options, all of which are currently vested and exercisable. All GB Options outstanding as of the GB merger will terminate and cease to be outstanding immediately following the GB merger pursuant to the 1999 Plan.

The table below sets forth, as of August 7, 2017, information with respect to the GB Options held by certain GB directors. Except as set forth on the table below, no executive officers or directors of GENBAND, GB or GB II hold GB Options.

Additional Equity-Based Payments

In addition to any shares of New Solstice common stock received in respect of GENBAND Class B Shares and GENBAND Class E Shares, certain executive officers and directors who hold GENBAND Class E Shares are also eligible to receive additional payments upon consummation of the mergers, in the form of shares of New Solstice common stock. The number of shares of New Solstice common stock to be received by each applicable executive officer and director will equal the number necessary so that, immediately following the mergers, such executive officer or director has received an aggregate number of shares of New Solstice common stock, either directly in respect of his or her GENBAND Class E Shares or through this additional payment, equal to the number that would have been received in respect of such executive officer's or director's GENBAND Class E Shares if the fair value of GENBAND equaled approximately $600 million as of the consummation of the mergers. If the actual fair value of GENBAND equals or exceeds approximately $600 million as of the consummation of the mergers, no additional payment (as described in this paragraph) will be paid to any executive officers or directors.

The table below sets forth the estimated number of shares of New Solstice common stock to be received in connection with the additional equity-based payments by the eligible executive officers and directors of GENBAND assuming the fair value of GENBAND equals $380.4 million, the estimated value of the shares of New Solstice common stock (based on an assumed value of each share of New

In addition, in connection with the GENBAND merger, all outstanding GENBAND phantom Class B Shares and GENBAND phantom Class E Shares shall be terminated in exchange for a cash payment. Such payment with respect to each GENBAND phantom Class B Share and GENBAND phantom Class E Share shall be equal to the amount of the distributions, if any, that would be received by a holder with respect to a GENBAND share that is comparable to such GENBAND phantom Class B Share or GENBAND phantom Class E Share. If the comparable GENBAND Class B Share or GENBAND Class E Share does not receive any consideration in the GENBAND merger, the GENBAND phantom Class B Share or GENBAND phantom Class E Share, as applicable, will be terminated for no consideration. No directors or executive officers of the GENBAND parties currently hold any GENBAND phantom equity awards.

Employment and Severance Agreements for Executive Officers

David Walsh is party to an employment agreement with GENBAND and certain of its subsidiaries. The employment agreement provides for severance benefits in the event of termination by GENBAND without "cause" or termination by the executive for "good reason" (each as defined in his employment agreement). In such situations, subject to his execution of a release of claims, Mr. Walsh would be eligible to receive: (i) an amount equal to his annual base salary plus $400,000, payable in 12 monthly installments, and (ii) payment of COBRA premiums for up to 12 months from the date of termination.

In addition, Daryl E. Raiford is party to an employment agreement with GENBAND and certain of its subsidiaries. The employment agreement provides for severance benefits in the event of termination by GENBAND without "cause" or termination by the executive for "good reason" (each as defined in his employment agreement). In such situations, subject to his execution of a release of claims, Mr. Raiford would be eligible to receive: (i) an amount equal to the sum of annual base salary and the annual target bonus in respect of the year of termination (or, if such termination occurs within 12 months following the closing of the mergers, 200% of such sum), payable in 12 monthly installments, (ii) a pro rata annual bonus in respect of the year of termination, payable when such bonuses are paid

181

Table of Contents

to active employees, and (iii) payment of COBRA premiums for up to 12 months from the date of termination.

The other executive officers are parties to severance agreements, which provide each of them with cash severance in the event of a termination of employment by GENBAND without "cause" or by him or her for "good reason" (each as defined in the applicable severance agreement), in either case, within six months following the consummation of the mergers. In such situations, the executive officer will be eligible to receive: (i) 50% of annual base salary, payable over six months, and (ii) payment of COBRA premiums for up to six months from the date of termination.

Assuming the closing of the mergers is completed and all of the executive officers of GENBAND, GB and GB II experienced a qualifying termination on such date, the estimated severance potentially payable to each executive officer is as follows:

Name |  | Cash Severance |  | Value of Continued Benefits |  | Aggregate Value of Potential Severance |

  Reflects the amount of severance in the event Mr. Raiford is terminated within 12 months of the consummation of the mergers (assuming pro rata bonus for the year of termination equals 100% of his target annual bonus).

Consulting Agreements for Directors

Alex Russo is party to a consulting agreement with GENBAND US LLC, a subsidiary of GENBAND, which provides for a monthly consulting fee of $33,333 or approximately $400,000 per annum. In addition, Mr. Russo is also eligible for a discretionary annual bonus with a target bonus opportunity equal to 50% of his annualized consulting fees. Mr. Russo's consulting term under his agreement will continue until terminated either by mutual agreement of the parties, by GENBAND US LLC upon fifteen days' written notice, or by either party in the event of a breach of the agreement. In the event of termination of the consulting term by GENBAND US LLC (other than due to breach of the agreement), Mr. Russo would continue to receive his consulting fees for six months following termination. The aggregate value of fifteen days' notice and the severance potentially payable to Mr. Russo under his consulting agreement is approximately $216,667.

Retention and Similar Bonus Agreements

Each of David Walsh, Steven Bruny, Patrick Joggerst, John McCready and Alex Russo is party to a retention bonus agreement with Genband Management Services Corp., a wholly owned subsidiary of GENBAND, which provides the executive officer or director with eligibility to receive a cash bonus in connection with the closing of the mergers and his continued service for at least six months following closing of the mergers. Fifty percent (50%) of each such cash bonus will be paid on the first regularly scheduled payroll cycle following (or, with respect to Mr. Russo, within 14 days following) the closing of the mergers, subject to the executive officer or director's continued service through the closing of the mergers. The remaining fifty percent (50%) will be paid on the earlier of (x) the six-month anniversary of following closing of the mergers, or (y) the executive officer or director's termination of service without "cause" or for "good reason" (each as defined in the applicable retention agreement)

182

Table of Contents

during the six-month period following the closing of the mergers, subject to the executive officer or director's continued service through the payment date.

Further, pursuant to his retention letter dated December 12, 2016, Daryl E. Raiford received a retention bonus of $1,060,000 on March 2, 2017. Mr. Raiford will not be entitled to any further retention bonus payment in connection with the consummation of the mergers. However, he will be eligible to receive an additional bonus of $1,060,000 in the event of a subsequent "material transaction" (as defined in his retention agreement) occurring after the consummation of the mergers.

Assuming the closing of the mergers is completed and all of the eligible GENBAND executive officers and directors would otherwise qualify for a bonus under their respective retention agreements, the total retention bonus potentially payable to each eligible executive officer and director in connection with the mergers is as follows:

Name |  | Retention Bonus |
--- | --- | --- | ---
Executive Officers |  |  |  |
David Walsh |  | $ | 2,550,000 |
Daryl E. Raiford |  | $ | 1,060,000 | (1)
Steven Bruny |  | $ | 450,000 |
Patrick Joggerst |  | $ | 435,000 |
John McCready |  | $ | 435,000 |
Directors |  |  |  |
Alex Russo |  | $ | 600,000 |

(1)
  Retention bonus for Daryl E. Raiford was paid on March 2, 2017. No further retention bonus payment will be made to Mr. Raiford in connection with the consummation of the mergers.

In addition, David Walsh is party to an arrangement with the OEP Stockholders pursuant to which, following the consummation of the mergers, he will be eligible to receive a payment equal to two and one-half percent (2.5%) of any cash proceeds received by such stockholders for their shares of New Solstice common stock to the extent such cash proceeds exceed the greater of $600 million and the fair equity value of GENBAND, as of the consummation of the GENBAND merger. The arrangement between the OEP Stockholders and Mr. Walsh is not related to and will not affect any carried interest payments Mr. Walsh may be entitled to as a former partner of One Equity Partners. New Solstice and its subsidiaries will not have any obligations under such arrangement.

Indemnification Arrangements

Under the merger agreement, New Solstice will indemnify, hold harmless and advance expenses to, among others, all past and present directors and officers of each GENBAND party and its respective subsidiaries (in all of their capacities) (i) to the same extent such persons are indemnified or have the right to advancement of expenses prior to the date of the merger agreement by any GENBAND party and (ii) to the fullest extent permitted by law, in each case for acts or omissions in their capacities as directors or officers occurring at or prior to the effective time. New Solstice will also include and cause to be maintained in effect in each GENBAND party's certificate of incorporation and by-laws, or equivalent organizational documents, after the effective time provisions regarding elimination of liability of directors, indemnification of officers and directors, and advancement of expenses which are, in the aggregate, no less advantageous to the intended beneficiaries than the corresponding provisions contained in the applicable GENBAND party's certificate of incorporation and by-laws, or equivalent organizational documents, and periodically advance to any such indemnitee its legal and other expenses (including the cost of any investigation and preparation incurred in connection therewith). New Solstice

183

Table of Contents

will cause to be maintained for a period of six years after the effective time the current policy of directors' and officers' liability insurance and fiduciary liability insurance maintained by GENBAND with respect to claims arising from facts or events that occurred on or before the effective time. See the section entitled "The Merger Agreement—Additional Agreements—Indemnification, Exculpation and Insurance" beginning on page 205 of this joint proxy statement/prospectus.

In addition, pursuant to indemnification agreements entered into by GENBAND and GB and certain of their respective directors and officers, GENBAND and GB have agreed to (i) indemnify their directors and officers to the fullest extent permitted by applicable law from and against any and all Costs (as defined in the applicable indemnification agreement) and (ii) advance all expenses (including attorney's fees and expenses) incurred by such indemnitee or any other Indemnified Person (as defined in the in the applicable indemnification agreement).

The following directors and officers of GENBAND entered into indemnification agreements with GENBAND on the following dates: Jon Bayless (May 28, 2010), Joseph Huffsmith (February 9, 2011), Keith Landau (August 4, 2015), James W. Koven (May 28, 2010), Mark Lancaster (May 28, 2010), Steve Levy (May 28, 2010), Ray Rothrock (May 28, 2010), Alexander Russo (February 9, 2011), David A. Walsh (August 4, 2015), Daryl E. Raiford (May 28, 2010), Jody Bishop (October 28, 2015), Steven Bruny (August 4, 2015), Patrick Joggerst (August 4, 2015), Rick Marmurek (August 4, 2015), John McCready (August 4, 2015) and Robin Wright (August 4, 2015).

Koven (May 24, 2010), Mark Lancaster (May 24, 2010), Steve Levy (May 24, 2010), Ray Rothrock (May 24, 2010), Alexander Russo (February 9, 2011), David A. Walsh (May 24, 2010), Daryl E. Raiford (May 28, 2010), Rick Smith (August 4, 2015) and Rick Marmurek (August 4, 2015).

Parachute Waiver Agreements

Certain compensatory payments and benefits in connection with the mergers may constitute "parachute payments" under Section 280G. As a result, certain executive officers and directors who have received, will receive or may become entitled to receive such parachute payments may enter into agreements with one or more of the GENBAND parties pursuant to which (i) such executive officers and directors waive their rights to certain parachute payments subject to receipt of shareholder approval of such payments in accordance with Section 280G and (ii) the GENBAND parties may agree to seek such shareholder approval for purposes of Section 280G. No such agreements have been entered into to date and the GENBAND parties have no obligation to obtain shareholder approval for purposes of Section 280G and receipt of such shareholder approval is not a condition to the consummation of the mergers.

Regulatory Matters Relating to the Transactions

Under the HSR Act, the transactions contemplated by the merger agreement may not be completed until notification and report forms have been filed with the Antitrust Division of the DOJ and the FTC and the applicable waiting period has expired or been terminated. Sonus and GENBAND each filed the required Notification and Report Forms pursuant to the HSR Act with the DOJ and the FTC on June 7, 2017, and on June 29, 2017, the FTC granted early termination of the applicable waiting period under the HSR Act, effective immediately.

Sonus and GENBAND derive revenues in certain other jurisdictions where merger control filings or clearances may be required or advisable. Under the merger agreement, the parties' obligations to effect the transactions contemplated by the merger agreement are conditioned on the receipt of any approvals required or deemed advisable under relevant antitrust laws. Sonus and GENBAND have

184

Table of Contents

agreed to make such filings and/or take such actions as promptly as practicable. An additional condition to the consummation of the transactions contemplated by the merger agreement is the absence of any decree, order, or injunction of any governmental authority of competent jurisdiction which prohibits or makes unlawful the consummation of any of the transactions contemplated by the merger agreement.

Sonus and the GENBAND parties have agreed to use their reasonable best efforts to obtain any government clearances or approvals, or expirations or terminations of waiting periods, required for the consummation of the transactions contemplated by the merger agreement under the HSR Act and any antitrust laws, and to take, or cause to be taken, all actions necessary, proper or advisable under applicable antitrust laws to consummate and make effective the transactions contemplated by the merger agreement as promptly as practicable. The use of such reasonable best efforts requires Sonus and the GENBAND parties to vigorously contest and resist any action or proceeding, including administrative or judicial action or proceeding, that would restrict, prevent or prohibit consummation of the transactions contemplated by the merger agreement, including reasonably pursuing administrative and judicial appeals. However, neither Sonus nor any GENBAND party is required to agree to any material divestitures, licenses, hold separate arrangements or similar matters, including material covenants affecting business operating practices, except to the extent any such divestitures, licenses, arrangements, matters or covenants would not reasonably be expected to be material to Sonus and the GENBAND parties, taken as a whole.

Material U.S. Federal Income Tax Consequences of the Sonus Merger to U.S. Holders of Sonus Common Stock

The following discussion is a summary of the material U.S. federal income tax consequences of the Sonus merger to holders of Sonus common stock.

This discussion addresses in general terms only the U.S. federal income tax consequences of the Sonus merger to holders of Sonus common stock who are "U.S. holders" (as defined below) and hold their shares as capital assets and does not address all of the U.S. federal income tax consequences that may be relevant to particular U.S. holders in light of their individual circumstances. This discussion does not address the tax consequences to holders of Sonus common stock who are subject to special rules, including, without limitation, financial institutions, tax-exempt organizations, insurance companies, dealers in securities or foreign currencies, foreign holders, persons who hold their shares as or in a hedge against currency risk, persons who hold their shares as a result of a constructive sale or as part of a conversion transaction, or holders who acquired their shares pursuant to the exercise of employee stock options or otherwise as compensation. In the case of a U.S. holder that is treated as a partnership for U.S. federal income tax purposes, the tax treatment of the partner will generally depend on the status of the partner and on the activities of the partnership. Partners of partnerships or other pass-through entities holding shares of Sonus common stock are urged to consult their own tax advisors as to the specific tax consequences of the Sonus merger to them. This discussion does not address the tax consequences to holders of Sonus common stock under any state, local or foreign tax laws or the U.S. federal estate or gift, Medicare net investment income, or alternative minimum tax provisions of the Code. It also does not discuss the tax consequences of transactions occurring prior to, concurrently with or after the mergers (whether or not such transactions are undertaken in connection with the mergers), including, without limitation, the exercise of stock options or warrants in anticipation of the mergers.

For purposes of this discussion, the term "U.S. holder" means a beneficial owner (other than a partnership or other pass-through entity) of Sonus common stock that is, for U.S. federal income tax purposes:

•
  an individual who is a citizen or resident of the United States;

185

Table of Contents

•
  a corporation, or other entity treated as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States, any state thereof or the District of Columbia;
•
  an estate the income of which is subject to U.S. federal income taxation regardless of its source; or
•
  a trust, if a U.S. court is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have authority to control all substantial decisions of the trust or if the trust has a valid election in effect to be treated as a U.S. person under applicable U.S. Treasury Regulations.

The following summary is not binding on the Internal Revenue Service (which we refer to as the IRS) or a court. It is based on the Code, laws, regulations, rulings and decisions in effect on the date hereof, all of which are subject to change, possibly with retroactive effect, which could result in U.S. federal income tax consequences different from those described below.

Holders of Sonus common stock are urged to consult their own tax advisors as to the specific tax consequences of the mergers to them, including the applicable federal, state, local and foreign tax consequences of the mergers to them and the effect of possible changes in tax laws.

General

It is a condition to Sonus' obligation to effect the transactions that Sonus receive an opinion of counsel in a form and substance reasonably satisfactory to Sonus, dated as of the closing date, to the effect that the exchange of Sonus common stock for New Solstice common stock in the Sonus merger will qualify as a reorganization under Section 368(a) of the Code or as a transaction that, taken together with the other mergers, will qualify as a transfer of property to New Solstice described in Section 351 of the Code.

This opinion will be based on certain facts, representations and assumptions, including representations of officers of Sonus, GENBAND, GB and GB II contained in officer's certificates delivered to counsel to Sonus pursuant to the merger agreement (which we refer to collectively as the tax opinion representations and assumptions). If any of the tax opinion representations and assumptions are incorrect, incomplete or inaccurate, the validity of the opinion described above may be affected and the tax consequences of the Sonus merger to holders of Sonus common stock could differ from those described herein.

Based on the tax opinion representations and assumptions, it is the opinion of WilmerHale that the Sonus merger will qualify as a reorganization under Section 368(a) of the Code or as a transaction that, taken together with the other mergers, will qualify as a transfer of property to New Solstice described in Section 351 of the Code and accordingly that the material U.S. federal income tax consequences of the Sonus merger to U.S. holders of Sonus common stock are as described below.

An opinion of counsel represents counsel's best legal judgment but is not binding on the IRS or any court. As a result, there can be no assurance that the IRS will not challenge the conclusions reflected in the opinion or that a court would not sustain such a challenge. Sonus does not intend to obtain a ruling from the IRS regarding the qualification of the Sonus merger as a reorganization under Section 368(a) of the Code or as a transaction that, taken together with the other mergers, will qualify as a transfer of property to New Solstice described in Section 351 of the Code. If the IRS were to successfully challenge the qualification of the Sonus merger as a reorganization under Section 368(a) of the Code and/or the qualification of the Sonus merger, together with the other mergers, as a transfer of property to New Solstice described in Section 351 of the Code, the tax consequences could differ from those described herein.

Exchange of Sonus Common Stock for New Solstice Common Stock

Subject to the discussion below relating to the receipt of cash in lieu of fractional shares, a U.S. holder of Sonus common stock that receives shares of New Solstice common stock in the Sonus merger:

•
  will not recognize any gain or loss upon the exchange of shares of Sonus common stock for shares of New Solstice common stock in the Sonus merger;
•
  will have a tax basis in the New Solstice common stock received in the Sonus merger (including any fractional share deemed received and sold as described below) equal to the tax basis of the Sonus common stock surrendered in the exchange therefor, which tax basis will be allocated between the New Solstice common stock received and any fractional share based on their relative fair market values; and
•
  will have a holding period in the shares of New Solstice common stock received in the Sonus merger (including any fractional share deemed received and sold as described below) that includes its holding period in its shares of Sonus common stock surrendered in exchange therefor.

Cash in Lieu of Fractional Shares

No fractional shares of New Solstice common stock will be issued in connection with the mergers. If a U.S. holder of Sonus common stock receives cash in lieu of a fractional share of New Solstice common stock in connection with the Sonus merger, the U.S. holder generally will be treated as having received the fractional share of New Solstice common stock pursuant to the Sonus merger and then as having sold that fractional share for cash. As a result, the U.S. holder will generally recognize capital gain or loss equal to the difference between the amount of cash received in lieu of such fractional share and the portion of the U.S. holder's tax basis in the Sonus common stock that is allocable to the fractional share. Such capital gain or loss will generally be long-term capital gain or loss if the holding period for the Sonus common stock exchanged therefor is more than one year as of the effective time of the Sonus merger. Long-term capital gain of certain non-corporate taxpayers, including individuals, is generally taxed at preferential rates. The deductibility of capital losses is subject to limitations.

U.S. holders that acquired different blocks of Sonus common stock at different times or different prices should consult their tax advisors regarding the manner in which gain or loss should be determined in their specific circumstances.

Backup Withholding

Certain non-corporate holders of Sonus common stock may be subject to backup withholding on cash received in connection with the Sonus merger. Backup withholding will not apply, however, to a U.S. holder who furnishes a correct taxpayer identification number and certifies that such U.S. holder is not subject to backup withholding on IRS Form W-9 or a substantially similar form or otherwise establishes an exemption from backup withholding. If a U.S. holder does not provide a correct taxpayer identification number on IRS Form W-9 or a substantially similar form, the holder may be subject to penalties imposed by the IRS. Backup withholding is not an additional tax, and any amounts withheld under the backup withholding rules may be refunded or credited against the U.S. holder's federal income tax liability, provided that the U.S. holder timely furnishes the required information to the IRS.

Accounting Treatment

U.S. GAAP requires the mergers to be accounted for using acquisition accounting pursuant to which Sonus has been determined to be the acquirer for accounting purposes. To make this determination, Sonus considered factors as indicated in ASC 805 and ASC 810, including relative

187

Table of Contents

ownership of equity interests in the combined company, board of director composition, shareholder ownership, voting control and anticipated management positions. Sonus will allocate the total purchase consideration to GENBAND's tangible and identifiable intangible assets acquired and liabilities assumed based on their fair values at the date of the completion of the mergers. Any excess purchase price after this allocation will be assigned to goodwill. Goodwill is not amortized, but is tested for impairment at least annually or more frequently if circumstances indicate potential impairment. The operating results of GENBAND will be reported as part of the combined company beginning on the date of the proposed mergers.

Final valuations of GENBAND's tangible and identifiable intangible assets acquired and liabilities assumed have not yet been completed. The completion of the valuation upon consummation of the mergers could result in significantly different amortization, depreciation and other expenses, revenue recognized and balance sheet classifications than those presented in the unaudited pro forma combined financial information included in this joint proxy statement/prospectus.

For further discussion of the accounting treatment, see the section entitled "Unaudited Pro Forma Condensed Combined Financial Statements" beginning on page 257 of this joint proxy statement/prospectus.

Restrictions on Sales of Shares by Certain Affiliates

The shares of New Solstice common stock to be issued in connection with the Sonus merger and the GENBAND mergers will be registered under the Securities Act and will be freely transferable under the Securities Act, except for shares of New Solstice common stock issued to any person who is deemed to be an "affiliate" (i) of Sonus or the GENBAND parties at the time of the Sonus special meeting or the GENBAND, GB or GB II special meeting, as applicable, or (ii) of New Solstice following the consummation of the Sonus merger and the GENBAND mergers. Persons who may be deemed to be "affiliates" include individuals or entities that control, are controlled by, or are under common control with Sonus, the GENBAND parties or New Solstice and may include our executive officers and directors, as well as our significant stockholders. Affiliates may not sell their shares of New Solstice common stock acquired in connection with the Sonus merger and/or the GENBAND mergers except pursuant to:

•
  an effective registration statement under the Securities Act covering the resale of those shares;
•
  Rule 144 under the Securities Act; or
•
  any other applicable exemption under the Securities Act.

Resales of New Solstice common stock held by certain parties are also subject to the terms and conditions set forth in the stockholders agreement and New Solstice's restated certificate of incorporation (which we refer to as the New Solstice charter). For a full description of the stockholders agreement and the New Solstice charter, see the sections entitled "Other Related Agreements—Principal Stockholders Agreement" and "Description of New Solstice Capital Stock" beginning on pages 214 and 289, respectively, of this joint proxy statement/prospectus.

This joint proxy statement/prospectus does not cover resales of New Solstice common stock by affiliates of Sonus, the GENBAND parties or New Solstice.

Listing of New Solstice Common Stock on NASDAQ

It is a condition to the completion of the mergers that the New Solstice common stock to be issued in connection with the transactions contemplated by the merger agreement be authorized for listing on NASDAQ, subject to official notice of issuance. It is anticipated that New Solstice common stock will be listed under the symbol "[ ]." New Solstice does not intend to avail itself of any of

188

Table of Contents

the exemptions from certain NASDAQ corporate governance requirements that are available to "controlled companies."

Delisting and Deregistering of Sonus Common Stock

If the mergers are completed, Sonus common stock will be delisted from NASDAQ and deregistered under the Exchange Act, and Sonus will no longer be required to file periodic reports with the SEC on account of Sonus common stock.

Amendment to Sonus By-laws

On May 22, 2017, the Sonus board of directors adopted an amendment to Sonus' Second Amended and Restated By-laws, as previously amended and restated on December 8, 2016 (which we refer to as the by-law amendment). The by-law amendment, among other things, designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for any stockholder to bring any derivative, fiduciary duty and other intra-corporate claims against Sonus, its directors, officers and other employees, including any claims challenging the mergers, unless Sonus otherwise consents in writing to an alternate forum.

The foregoing description of the by-law amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the by-law amendment. A copy of the by-law amendment is filed as an exhibit to Sonus' Current Report on Form 8-K, filed with the SEC on May 23, 2017, and is incorporated herein by reference. See the section entitled "Where You Can Find More Information" beginning on page 350 of this joint proxy statement/prospectus.

Litigation Related to the Mergers

On July 19, 2017, Holdings filed the Holdings Complaint against the Holdings Lawsuit Defendants in Texas state court, District of Dallas County (Case No. DC-17-08630) based on the Earn-Out Agreement. The Holdings Complaint alleges that: (i) Sonus purportedly breached the Earn-Out Agreement by implementing the Taqua Restructuring Initiative that was allegedly intended to undermine Taqua's business and Sonus' payment obligation; and (ii) Sonus purportedly acquired Taqua for the purpose of eliminating Taqua as a competitor before the mergers, and that Sonus never intended to promote Taqua products.

The Holdings Complaint purports to seek monetary damages for Sonus' alleged breach of the Earn-Out Agreement and an injunction of both the Taqua Restructuring Initiative and the mergers.

The Holdings Lawsuit Defendants believe Holdings' allegations are without merit and intend to contest the lawsuit vigorously.

For additional information, see Sonus' Quarterly Report on Form 10-Q for the period ended June 30, 2017.

Structure of the Mergers

The merger agreement provides, upon the terms and subject to the conditions thereof, for four separate mergers, as described in more detail below, pursuant to which the combined companies will operate under a new holding company, New Solstice, which will be listed on NASDAQ under the symbol "[ ]." Following the mergers described below, the existing holders of Sonus common stock

190

Table of Contents

will own approximately 50% of the common stock of New Solstice, and the shareholders of the GENBAND parties will collectively own approximately 50% of the common stock of New Solstice. The mergers will be effected as described below.

At the effective time, the following four mergers will be effected:

•
  Solstice Merger Sub will merge with and into Sonus, at which time the separate corporate existence of Solstice Merger Sub will cease, and Sonus will survive the merger as a wholly owned subsidiary of New Solstice (which we refer to as the Sonus merger);
•
  Cayman Merger Sub will merge with and into GENBAND, at which time the separate existence of Cayman Merger Sub will cease, and GENBAND will survive the merger as a direct or indirect wholly owned subsidiary of New Solstice (which we refer to as the GENBAND merger);
•
  GB will merge with and into GB Merger Sub, at which time the separate corporate existence of GB will cease, and GB Merger Sub will survive the merger as a direct wholly owned subsidiary of New Solstice (which we refer to as the GB merger); and
•
  GB II will merge with and into GB Merger Sub, at which time the separate corporate existence of GB II will cease, and GB Merger Sub will survive the merger as a direct wholly owned subsidiary of New Solstice (which we refer to as the GB II merger, and together with the GENBAND merger and the GB merger, the GENBAND mergers, and the GENBAND mergers together with the Sonus merger, the mergers).

As of the effective time of the mergers, New Solstice will own all of the issued and outstanding shares of capital stock of the surviving entities to the mergers, as further described below.

Sonus Merger

At the effective time of the Sonus merger, each share of common stock of Sonus that is owned by Sonus immediately prior to the effective time will automatically be cancelled and extinguished and will cease to exist, and no consideration will be paid for such shares. Each other share of Sonus common stock issued and outstanding immediately prior to the effective time will be converted into the right to receive one share of New Solstice common stock. Each share of common stock of Solstice Merger Sub issued and outstanding immediately prior to the effective time will be converted into one share of common stock of Sonus (as the surviving entity of the Sonus merger).

GENBAND Merger

At the effective time of the GENBAND merger, each share of capital stock or other equity interests of GENBAND owned by GENBAND will automatically be cancelled and extinguished and will cease to exist, and no consideration will be paid for such shares. Each share of capital stock or other equity interests of GENBAND owned by GB or GB II or any of their respective subsidiaries as of immediately prior to the effective time of the GENBAND merger will be converted into one share of GENBAND (as the surviving entity of the GENBAND merger). Each share of capital stock or other equity interests of GENBAND other than those described above will be converted into the right to receive a portion of a share of New Solstice common stock and such share's portion of the promissory note issued by New Solstice to shareholders of GENBAND that the holder of such GENBAND share is entitled to receive upon a Realization Event as defined in the GENBAND Articles of Association assuming that the total Realization Consideration as defined in the GENBAND Articles of Association is equal to the value of the total number of Sonus common stock outstanding immediately prior to the GENBAND merger plus the aggregate value of the promissory note to be issued by New Solstice, and all such shares of capital stock or other equity interests of GENBAND will cease to be outstanding and will automatically be cancelled and extinguished and will cease to exist. For additional details of the

191

Table of Contents

promissory note, see the section entitled "Other Related Agreements—The Promissory Note" beginning on page 217 of this joint proxy statement/prospectus.

All outstanding limited liability company interests of Cayman Merger Sub will be converted into one share of GENBAND (as the surviving entity of the GENBAND merger).

GB Merger

At the effective time of the GB merger, each share of GB common stock owned by GB will automatically be cancelled and extinguished and will cease to exist and no consideration will be paid for such shares. Each other share of GB common stock (other than dissenting shares) will be converted into the right to receive a share of New Solstice common stock multiplied by an exchange ratio equal to (a) the total number of shares of New Solstice common stock that GB would be entitled to receive upon a Realization Event as defined in the GENBAND Articles of Association assuming the total Realization Consideration as defined in the GENBAND Articles of Association is equal to the value of total number of shares of Sonus common stock outstanding immediately prior to the GB merger, divided by (b) the total number of shares of GB common stock outstanding immediately prior to the effective time of the GB merger (other than the shares of GB common stock that will be cancelled as described above). In exchange for such shares of New Solstice common stock (if any), each share of GB common stock will automatically be cancelled and extinguished and will cease to exist. Each limited liability company interest of GB Merger Sub will remain unchanged and will continue to remain outstanding as a limited liability company interest in the GB entity surviving the GB merger.

GB II Merger

At the effective time of the GB II merger, each share of GB II common stock owned by GB II will automatically be cancelled and extinguished and will cease to exist and no consideration will be paid for such shares. Each other share of GB II common stock (other than dissenting shares) will be converted into the right to receive a share of New Solstice common stock multiplied by an exchange ratio equal to (a) the total number of shares of New Solstice common stock that GB II would be entitled to receive upon a Realization Event as defined in the GENBAND Articles of Association assuming the total Realization Consideration as defined in the GENBAND Articles of Association is equal to the value of the total number of shares of Sonus common stock outstanding immediately prior to the GB II merger, divided by (b) the total number of shares of GB II common stock outstanding immediately prior to the effective time of the GB II merger (other than the shares of GB II common stock that will be cancelled as described above). In exchange for such shares of New Solstice common stock (if any), each share of GB II common stock will automatically be cancelled and extinguished and will cease to exist. Each limited liability company interest of GB Merger Sub will remain unchanged and will continue to remain outstanding as a limited liability company interest in the GB entity surviving the GB II merger.

Closing and Effective Times of the Mergers

The closing is expected to occur concurrently with all necessary filings with the applicable governmental entities in connection with the mergers on a date as specified by the parties and no later than the second business day after the satisfaction or waiver of the conditions set forth in the merger agreement (other than those conditions that by their nature are to be satisfied on the closing date, but subject to the satisfaction or waiver of those conditions). For a description of the conditions to the closing of the mergers, see the section entitled "The Merger Agreement—Conditions to the Mergers" beginning on page 207 of this joint proxy statement/prospectus. The mergers will become effective at the time and on the date on which the relevant certificate of merger is filed with the applicable governmental entity, or later if the parties so agree and specify in such certificates. At the effective time of the mergers, the form of New Solstice charter attached to this joint proxy statement/prospectus

As described above, at the effective time of the Sonus merger, each share of Sonus common stock issued and outstanding immediately prior to the effective time of the Sonus merger (other than shares of Sonus common stock owned by Sonus immediately prior to the effective time of the Sonus merger) will be converted into and become the right to receive one share of New Solstice common stock.

As described above, at the effective time of the GENBAND merger, each GENBAND share issued and outstanding immediately prior to the effective time of the GENBAND merger (other than shares of capital stock or other equity interests of GENBAND owned by GENBAND, GB or GB II immediately prior to the effective time of the GENBAND merger) will be converted into and become the right to receive a portion of a share of New Solstice common stock and such share's portion of the promissory note issued by New Solstice to shareholders of GENBAND.

As described above, at the effective time of the GB merger and the GB II merger, respectively, each share of GB and GB II capital stock issued and outstanding immediately prior to the effective time of the GB merger and GB II merger, respectively (other than GB common stock owned by GB or GB II common stock owned by GB II, in each case, immediately prior to the effective time of the GB merger or the GB II merger, respectively), will be converted into and become the right to receive a share of New Solstice common stock multiplied by the applicable exchange ratio described above.

Treatment of Sonus Equity Awards

Sonus Stock Options

Each Sonus stock option that is outstanding as of the date that is five business days prior to the closing date of the Sonus merger will become vested in full as of that date (to the extent not previously vested), and the holders of such Sonus stock options will be permitted to exercise such awards on or prior to the date that is three business days prior to the closing date of the Sonus merger.

To the extent not exercised as of the end of day that is three business days prior to the closing date, each Sonus stock option granted under the Specified Sonus Plans will not be permitted to be exercised between such time and the effective time and will, as of the effective time, be assumed by New Solstice and converted into an option to purchase (i) that number of shares of New Solstice common stock (rounded down to the nearest whole share) equal to the product obtained by multiplying (a) the number of shares of Sonus common stock subject to such option immediately prior to the

193

Table of Contents

effective time of the mergers by (b) the Sonus exchange ratio, (ii) at an exercise price per share equal to the quotient (rounded up to the nearest whole cent) obtained by dividing (a) the exercise price per share of such option immediately prior to the effective time of the mergers by (b) the Sonus exchange ratio. Each assumed Sonus stock option will otherwise continue to have, and be subject to, the same terms and conditions (including vesting arrangements and other terms and conditions set forth in the applicable plan and option agreement) as are in effect immediately prior to the effective time, except that New Solstice or the board of directors or the compensation committee of New Solstice, as applicable, has any and all amendment and administrative authority with respect to such assumed option (subject, in the case of any amendment, to the required consent of the affected holder thereof).

Effective as of the end of the day that is three business days prior to the closing date of the Sonus merger, all Sonus stock options other than Sonus stock options granted under the Specified Sonus Plans will be cancelled to the extent not exercised as of such time.

Sonus RSUs

Each Sonus RSU that is vested by its terms as of immediately prior to the effective time (after taking into account any vesting of the Sonus RSU that occurs by reason of the mergers) will have been settled in shares of Sonus common stock.

Each Sonus RSU that is not then vested by its terms (after taking into account any accelerated vesting of the Sonus RSU that occurs by reason of the mergers) and settled in shares of Sonus common stock will, as of the effective time of the mergers, be assumed by New Solstice and converted into a new award of restricted stock units of New Solstice covering a number of shares of New Solstice common stock equal to the product (rounded down to the nearest whole share) of the total number of shares of Sonus common stock then underlying such Sonus RSU multiplied by the Sonus exchange ratio. Each assumed Sonus RSU will otherwise continue to have, and be subject to, the same terms and conditions (including the vesting arrangements (and accelerated vesting arrangements) and other terms and conditions set forth in any applicable plan and award agreement) as in effect immediately prior to the effective time of the mergers, except that New Solstice or the board of directors or the compensation committee of New Solstice, as applicable, has any and all amendment and administrative authority with respect to such assumed RSU (subject, in the case of any amendment, to the required consent of the affected holder thereof).

Sonus Restricted Shares

Each Sonus Restricted Share that will not be vested by its terms (after taking into account any vesting of the Sonus Restricted Share that occurs by reason of the mergers) shall, at the effective time, be converted into New Solstice common stock and shall otherwise continue to have, and be subject to, the same terms and conditions (including the forfeiture and repurchase restrictions set forth in any applicable plan and award agreement) as in effect immediately prior to the effective time, except that New Solstice or the board of directors or the compensation committee of New Solstice, as applicable, has any and all amendment and administrative authority with respect to such terms and conditions (subject, in the case of any amendment, to the required consent of the affected holder thereof).

Sonus ESPP

With respect to the Sonus ESPP, if the effective time of the mergers occurs on or before the "Purchase Date" relating to the applicable "Offering Period" in effect on the date of the merger agreement (as such terms are defined in the Sonus ESPP) and there are ESPP options then outstanding with respect to such Offering Period, the Sonus board of directors will provide a "New Purchase Date" (as defined in the Sonus ESPP) for such Offering Period, and any ESPP options will automatically be exercised on the New Purchase Date pursuant to the terms of the Sonus ESPP.

If the effective time occurs after the exercise date relating to the applicable Offering Period in effect on the date of the merger agreement, the board of directors of Sonus will timely suspend the Sonus ESPP as of immediately following the exercise date relating to such Offering Period. All shares of Sonus common stock due upon exercise of ESPP options will be issued prior to the effective time of the mergers and no ESPP options will be outstanding as of the effective time of the mergers.

Appraisal Rights

Sonus Stockholder Appraisal Rights

Under the DGCL, Sonus stockholders do not have appraisal rights in connection with the Sonus merger.

GENBAND Shareholder Dissenter Rights

With respect to the GENBAND merger, the Companies Law (2016 Revision) provides for a right of dissenting stockholders, in certain situations, to be paid the fair value of their shares upon their dissenting to the merger if they follow a prescribed procedure as further discussed in the section entitled "Appraisal Rights" beginning on page 340 of this joint proxy statement/prospectus. Notwithstanding the foregoing, in accordance with the GENBAND Stockholders Agreement, OEP has the right to cause a majority of shares held by the shareholders of GENBAND to vote in favor of the approval of the GENBAND merger. If OEP exercises this right, then shareholders holding a majority of such shares of GENBAND would waive their dissenter's rights in connection with the GENBAND merger. See the section entitled "Appraisal Rights" beginning on page 340 of this joint proxy statement/prospectus for further discussion of appraisal rights of GENBAND shareholders.

GB and GB II Stockholder Appraisal Rights

As a statutory matter appraisal rights are available with respect to the GB merger and the GB II merger under Section 262 of the DGCL. However, under the terms of the GENBAND Stockholders Agreement, OEP has the right to require a majority of common stock held by GB and GB II stockholders to vote in favor of the GB merger or the GB II merger, as applicable. To the extent a GB stockholder or GB II stockholder does not vote in favor of (or return a separate proxy voting in favor of) the adoption of the merger agreement and the approval of the GB merger or GB II merger, as applicable, OEP may exercise the proxy granted to it by the GENBAND Stockholders Agreement to vote any such stockholder's shares in favor of the adoption of the merger agreement and the approval of the GB merger or GB II merger, as applicable. Under Section 262 of the DGCL, only stockholders who do not vote in favor of a merger are entitled to exercise appraisal rights in connection therewith. Accordingly, any stockholder whose shares are voted in favor of the GB merger or the GB II merger, including pursuant to the provisions of the GENBAND Stockholders Agreement, will not be entitled to exercise appraisal rights in connection with such mergers. See the section entitled "Appraisal Rights" beginning on page 340 of this joint proxy statement/prospectus for further discussion of appraisal rights of GB and GB II stockholders.

Upon surrender of a certificate for cancellation to the exchange agent together with a letter of transmittal, duly executed and completed in accordance with the instructions thereto, the holder of such certificate will be entitled to receive in exchange therefor a New Solstice certificate representing that number of whole shares of New Solstice common stock to which the holder thereof is entitled, together with a check for the cash to be paid in lieu of fractional shares, if any.

Notwithstanding the foregoing, until the earlier of the receipt of the Sonus stockholder approval and any termination of the merger agreement, if after the date of the merger agreement Sonus receives a written bona fide Sonus acquisition proposal, that was not, directly or indirectly, solicited, initiated or knowingly encouraged, and that the board of directors of Sonus has determined in good faith, after consultation with its outside legal counsel and financial advisors (i) constitutes a superior proposal or (ii) could reasonably be expected to result in a superior proposal, then Sonus and its subsidiaries and representatives may, to the extent that the board of directors of Sonus has determined in good faith, after consultation with its outside legal counsel, that a failure to take such actions would be inconsistent with its fiduciary duties to Sonus' stockholders under applicable law: (a) furnish nonpublic information to the third party making such Sonus acquisition proposal, if, and only if, prior to furnishing such information, Sonus receives from the third party an executed confidentiality agreement with provisions no less restrictive to such third party with respect to the use or disclosure of nonpublic information than the confidentiality agreement between Sonus and GENBAND and (b) engage in discussions or negotiations with the third party with respect to such Sonus acquisition proposal.

Notwithstanding the foregoing, nothing contained in the merger agreement will prevent Sonus or the board of directors of Sonus from, at any time prior to, but not after, the receipt of the Sonus stockholder approval, in response to the receipt of a written Sonus acquisition proposal prior to the closing and not otherwise received in violation of the merger agreement, (i) terminating the merger agreement in order to enter into a definitive written agreement with respect to such Sonus acquisition proposal or (ii) effecting a change in recommendation, if and only if, prior to taking any of the actions described in clauses (i) or (ii), (a) the board of directors of Sonus determines in good faith, after consultation with its outside legal counsel and financial advisors, that such Sonus acquisition proposal constitutes a superior proposal, (b) GENBAND shall have received written notice of Sonus' intention

202

Table of Contents

to take such action at least four business days prior to the taking of such action by Sonus, (c) during the four business days following the receipt by GENBAND of the notice of a superior proposal, Sonus, if requested by GENBAND, will make its representatives available to negotiate with GENBAND regarding any revisions to the terms of the transactions proposed by GENBAND in response to such Sonus acquisition proposal, and (d) at the end of the four business day period described in the foregoing clause (c) the board of directors of Sonus continues to believe, in good faith after consultation with its outside legal counsel and financial advisors, and after taking into account any modifications to the terms of the transactions that are proposed in a written offer by GENBAND, that such Sonus acquisition proposal continues to constitute a superior proposal and that failure to take such action would be inconsistent with the Sonus' directors' fiduciary duties under applicable law.

Notwithstanding the foregoing, nothing will prevent the Sonus board from, prior to the receipt of the Sonus stockholder approval, effecting a change in recommendation if the board of directors of Sonus determines that an "intervening event" has occurred and is continuing and if, prior to taking such action, the Sonus board determines in good faith, after consultation with its outside legal counsel, that failure to take such action would be inconsistent with the Sonus directors' fiduciary duties under applicable law, provided that GENBAND received written notice at least four business days prior to the taking of such action by the Sonus board specifying in reasonable detail the circumstances related to such determination and during such notice period, Sonus, if requested by GENBAND, makes available its representatives to negotiate with GENBAND to revise the terms of the transactions and the Sonus board continues to believe that failing to take such action would be inconsistent with the Sonus directors' fiduciary duties under applicable law.

For purposes of the merger agreement, "intervening event" means any material event, development or change in circumstances (i) that first becomes known to the Sonus board after the date of the merger agreement, to the extent any such event, development or change in circumstances was not reasonably foreseeable by the Sonus board, or (ii) the consequences of which were not reasonably foreseeable by the Sonus board; provided, however, that in no event shall the following events, developments or changes in circumstances constitute an intervening event: (a) the receipt, existence or terms of a Sonus acquisition proposal or any matter relating thereto or consequence thereof; (b) any change in the price, or change in trading volume, of the Sonus common stock (provided, however, that the exception contained in this clause (b) shall not apply to the underlying causes giving rise to or contributing to such change or prevent any of such underlying causes from being taken into account in determining whether an intervening event has occurred); and (c) meeting or exceeding internal or analysts' expectations, projections or results of operations (provided, however, that the exception contained in this clause (c) shall not apply to the underlying causes giving rise to or contributing to such circumstances or prevent any of such underlying causes from being taken into account in determining whether an intervening event has occurred).

For purposes of the merger agreement, "superior proposal" means a bona fide written Sonus acquisition proposal (except that references in the definition of "Sonus acquisition proposal" to 15% shall be replaced by 50%) made after the date of the merger agreement by any person other than GENBAND or its subsidiaries, on terms that the Sonus board determines in good faith, after consultation with its outside legal counsel and financial advisors, and considering such factors as the Sonus board considers to be appropriate (including the timing and likelihood of consummation of such proposal), are more favorable to Sonus stockholders than the transactions contemplated by the merger agreement, taking into account any change to the transaction proposed by GENBAND.

No Solicitation by GENBAND Parties

Each GENBAND party has agreed to not, directly or indirectly, (i) maintain, initiate or solicit or knowingly encourage or facilitate (including by way of any inquiries with respect to, or the making of, any proposal which constitutes, or would reasonably be expected to lead to) a GENBAND acquisition

203

Table of Contents

proposal, (ii) engage in any negotiations concerning, or provide any confidential information or data regarding GENBAND or its subsidiaries to any person relating to, a GENBAND acquisition proposal, (iii) approve or recommend, or propose publicly to approve or recommend, any GENBAND acquisition proposal, (iv) approve or recommend, or propose publicly to approve or recommend, or execute or enter into, any letter of intent, agreement in principle, merger agreement, acquisition agreement, option agreement or other similar agreement relating to any GENBAND acquisition proposal, (v) take any action to make the provisions of any takeover statute inapplicable to any transactions contemplated by a GENBAND acquisition proposal, or (vi) propose publicly or agree to do any of the foregoing.

GENBAND agrees that it and its subsidiaries shall, and that they shall cause their respective representatives to, (i) immediately cease and cause to be terminated any existing activities, discussions or negotiations with any person (other than the parties) conducted prior to the date of the merger agreement with respect to any GENBAND acquisition proposal and (ii) request each third party that has heretofore executed a confidentiality agreement that relates to a GENBAND acquisition proposal (other than Sonus) to return or destroy all confidential information regarding GENBAND or its subsidiaries heretofore furnished to such third party by GENBAND or on its behalf.

Prior to the effective time, GENBAND will promptly orally notify Sonus of any request for information or any inquiries, proposals or offers relating to a GENBAND acquisition proposal indicating, in connection with such notice, the name of such person making such request, inquiry, proposal or offer and the material terms and conditions of any proposals or offers and GENBAND shall provide to Sonus written notice of any such inquiry, proposal or offer within 24 hours of such event and copies of any written or electronic correspondence to or from any person making a GENBAND acquisition proposal (or its representatives). GENBAND shall keep Sonus informed orally, as soon as is reasonably practicable, of the status of any GENBAND acquisition proposal, including with respect to the status and material terms of any such proposal or offer and whether any such proposal or offer has been withdrawn or rejected and GENBAND shall provide to Sonus written notice of any such withdrawal or rejection and copies of any written proposals or requests for information within 24 hours.

For purposes of the merger agreement, "GENBAND acquisition proposal" means any proposal or offer made by any person other than Sonus or its subsidiaries with respect to (i) a merger, consolidation, share exchange, business combination, reorganization, recapitalization, dissolution, liquidation or similar transaction involving any GENBAND party, (ii) any purchase of an equity interest (including by means of a tender or exchange offer) representing an amount greater than a 15% voting or economic interest in any GENBAND party or (iii) any purchase of assets, securities or ownership interests representing an amount greater than 15% of the consolidated assets (including stock of the subsidiaries of any GENBAND party), consolidated net revenues or earnings before interest, taxes, depreciation and amortization of any GENBAND party and its subsidiaries taken as a whole.

Additional Agreements

Preparation of Form S-4 and the Joint Proxy Statement/Prospectus

Sonus and GENBAND have delivered this joint proxy statement/prospectus pursuant to the merger agreement, which requires the parties to jointly prepare and file this joint proxy statement/prospectus following each party's opportunity for review, comment and approval. Sonus and GENBAND will advise each other, promptly after receiving notice of effectiveness of the registration statement or any supplement or amendment that has been filed, of any request by the SEC for the amendment or supplement to, or of any comments or responses to, the registration statement on Form S-4 of which this joint proxy statement/prospectus forms a part (which we refer to as the

204

Table of Contents

Form S-4). Each of Sonus and the GENBAND parties shall, and Sonus shall cause New Solstice to, use its reasonable best efforts to have the Form S-4 declared effective under the Securities Act as promptly as practicable and to maintain the effectiveness of the Form S-4 as long as is necessary to consummate the mergers and the other transactions contemplated by the merger agreement. Sonus shall cause the joint proxy statement/prospectus to be mailed to its stockholders and the stockholders of the GENBAND parties as promptly as practicable after the Form S-4 is declared effective by the SEC and in any event within five days thereafter.

Required Actions and Governmental Approvals

The Sonus parties and the GENBAND parties have agreed to use its reasonable best efforts to (i) take, or cause to be taken, all actions, and do, or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable to consummate and make effective the transactions contemplated by the merger agreement as promptly as practicable, (ii) as promptly as practicable, obtain from any governmental authority or any other third party any consents or approvals required to be obtained or made by such party or any of its subsidiaries in connection with the merger agreement and (iii) as promptly as practicable (and, in the case of the HSR filing, within 10 business days of the execution of the merger agreement) make all necessary filings, required by the SEC and applicable state securities law, the HSR Act or other law. The parties agree to cooperate with each other in connection with the making of all such filings and shall use their respective reasonable best efforts to furnish to each other all information required for any application or other filing to be made pursuant to the rules and regulations of any law.

Each party has agreed to cooperate and use its reasonable best efforts to vigorously contest and resist any action or proceeding, including administrative or judicial action or proceeding, and to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order (whether temporary, preliminary or permanent) that is in effect and that restricts, prevents or prohibits consummation of the mergers, including reasonably pursuing administrative and judicial appeal. Notwithstanding the foregoing, no party will be required to agree to any material divestitures, licenses, hold separate arrangements or similar matters, including material covenants affecting business operating practices, except to the extent any such divestitures, licenses, arrangements, matters or covenants would not reasonably be expected to be material to the GENBAND parties and Sonus, taken as a whole.

No party will make any settlement offers (or accept any such settlement offer) or negotiate any consent decree, consent order or undertaking with any governmental authority relating to the transactions contemplated by the merger agreement without the prior consent of the other party, which shall not be unreasonably withheld, delayed or conditioned.

Indemnification, Exculpation and Insurance

New Solstice will indemnify, hold harmless and advance expenses to all past and present directors and officers of Sonus, each GENBAND party and each of their subsidiaries (in all of their capacities) (i) to the same extent such persons are indemnified or have the right to advancement of expenses prior to the date of the merger agreement by Sonus or any GENBAND party and (ii) to the fullest extent permitted by law, in each case for acts or omissions in their capacities as directors or officers occurring at or prior to the effective time. New Solstice will also include and cause to be maintained in effect in Sonus' (as the surviving entity of the Sonus merger) and each GENBAND party's (each, as the surviving entity of the applicable GENBAND party merger) certificate of incorporation and by-laws, or equivalent organizational documents, after the effective time provisions regarding elimination of liability of directors, indemnification of officers and directors, and advancement of expenses which are, in the aggregate, no less advantageous to the intended beneficiaries than the corresponding provisions contained in Sonus' or each GENBAND party's certificate of incorporation and by-laws, or equivalent

205

Table of Contents

organizational documents, and periodically advance to any such indemnitee its legal and other expenses (including the cost of any investigation and preparation incurred in connection therewith). New Solstice will cause to be maintained for a period of six years after the effective time the current policies of directors' and officers' liability insurance and fiduciary liability insurance maintained by Sonus and GENBAND with respect to claims arising from facts or events that occurred on or before the effective time. In no event shall New Solstice or Sonus or any GENBAND party be required to expend in any one year an amount in excess of 300% of the last annual premium paid by Sonus or the applicable GENBAND party for such insurance prior to the date of the merger agreement. If the annual premiums of such insurance coverage exceed such amount, Sonus and the applicable GENBAND party will be obligated to obtain a policy with the greatest coverage available for a cost not exceeding such amount. Sonus and each GENBAND party may extend coverage, effective as of the effective time, under its director and officers policy by obtaining a six-year "tail" policy prior to the closing on terms and conditions no less advantageous to the covered persons than Sonus' and GENBAND's existing directors and officers insurance, and such "tail" policy will be deemed to satisfy Sonus' and GENBAND's obligations. If such "tail" policy has been obtained by Sonus or GENBAND prior to the closing, Sonus (as the surviving entity of the Sonus merger) or GENBAND will maintain such policies in full force and effect and continue to honor Sonus' or GENBAND's obligations thereunder.

Tax Matters

None of Sonus, GENBAND, GB, GB II, New Solstice, or any of their respective subsidiaries shall take any action, or fail to take any reasonable action, as a result of which (i) the exchange of Sonus common stock for New Solstice common stock pursuant to the Sonus merger would reasonably be expected to fail to qualify either as a reorganization under Section 368(a) of the Code or as a transaction that, taken together with the other mergers, qualifies as a transfer of property to New Solstice described in Section 351 of the Code or (ii) the exchange of GENBAND shares for New Solstice common stock pursuant to the GENBAND merger, taken together with the other mergers, would reasonably be expected to fail to qualify as a transaction qualifying as a transfer of property to New Solstice described in Section 351 of the Code.

Each of Sonus and GENBAND shall use its reasonable best efforts to obtain the opinion of counsel referred to below under "—Conditions to the Mergers." Each of Sonus, GENBAND, GB and GB II shall deliver to counsel for Sonus and counsel for GENBAND an officer's certificate, dated as of the closing date, to enable such counsel to render such opinions.

So long as the opinions of counsel are given, each party agrees to report for U.S. federal income tax purposes the exchange of GENBAND shares for New Solstice common stock pursuant to the GENBAND merger, taken together with the exchange of Sonus common stock for New Solstice common stock pursuant to the Sonus merger, as a transaction qualifying as a transfer of property to New Solstice described in Section 351 of the Code, except as otherwise required as a result of a final determination of a taxing authority. However, the parties may treat the Sonus merger as a reorganization within the meaning of Section 368(a) of the Code.

Employee Matters

New Solstice has agreed to honor all employment and severance agreements of Sonus and the GENBAND parties and all benefits and obligations under the other plans of Sonus and the GENBAND parties. New Solstice will retain the right to amend or terminate any of the foregoing agreements, plans and arrangements to the extent permitted by the terms thereof and law. This agreement only applies to employees within the United States and those not covered by collective bargaining or other labor agreements. New Solstice has agreed to comply with the requirements of law with respect to the treatment of non-U.S. employees and those covered by collective bargaining and to honor all benefit plans of Sonus and the GENBAND parties and all collective bargaining agreements

206

Table of Contents

or other labor agreements to which Sonus, GENBAND, or any of their subsidiaries is a party or otherwise bound.

New Solstice will provide full credit for purposes of eligibility, vesting and determination of the level of benefits (other than benefit accrual under a defined benefit pension plan) under any employee benefit plans or arrangements maintained by New Solstice or any of its subsidiaries as of the effective time for such employees' service with GENBAND or Sonus or any subsidiary of GENBAND or Sonus to the same extent recognized by GENBAND or Sonus immediately prior to the effective time.

New Solstice will use commercially reasonable efforts to:

•
  waive all limitations as to preexisting conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to the employees under any medical or dental benefit plans that the employees may be eligible to participate in after the effective time of the mergers, other than limitations or waiting periods that are already in effect with respect to such employees and that have not been satisfied as of the effective time under any medical or dental benefit plan; and
•
  to the extent permitted by the applicable medical or dental plan, provide each employee with credit for the year in which the effective time occurs for any co-payments and deductibles paid prior to the effective time in satisfying any applicable deductible or out-of-pocket requirements under any medical and dental plans that the affected employees are eligible to participate in after the effective time.

Sonus has agreed to cause New Solstice to adopt or assume, prior to or as of the effective time of the mergers, an equity compensation plan providing for the granting of stock options and other equity-based awards to the employees of New Solstice, Sonus (as the surviving entity of the Sonus merger), GENBAND (as the surviving entity of the GENBAND merger) and their respective subsidiaries. It is currently expected that New Solstice will assume one or more of Sonus' existing equity compensation plans and that future grants of stock options and other equity-based awards by New Solstice will be made under such assumed plan or plans.

GENBAND Indebtedness

Prior to the closing, GENBAND is obligated to deliver to Sonus executed payoff letters, to be effective upon the closing, from each lender of indebtedness of GENBAND and any of its subsidiaries as of immediately prior to the closing. At the closing and on behalf of the applicable GENBAND party, New Solstice will pay, in cash by wire transfer of immediately available funds, such indebtedness in the amounts set forth in the payoff letters.

•
  GENBAND terminates the merger agreement due to a change in the Sonus board's recommendation;

•
  the merger agreement is terminated by Sonus or GENBAND because the Sonus stockholders have not approved the Sonus merger and prior to such meeting there was a change in the Sonus board recommendation or the Sonus board fails to affirm its recommendation of such merger after a Sonus acquisition proposal is announced.

Amendment and Waiver

Amendment

The merger agreement may be amended only in writing, and only by the parties thereto, by action taken or authorized by their boards of directors, at any time before or after approval of matters presented in connection with the mergers by the stockholders of Sonus and the other parties to such mergers, but after any such stockholder approval, no amendment shall be made which by law requires the further approval of stockholders unless such amendment is subject to such further approval.

Waiver

No action taken pursuant to the merger agreement, including any investigation by or on behalf of any party to the merger agreement, or delay or omission in the exercise of any right, power or remedy accruing to any party to the merger agreement as a result of any breach or default thereunder by any other party to the merger agreement will be deemed to constitute a waiver by the party taking such action of compliance with any representations, warranties, covenants or agreements contained in the merger agreement. The waiver by any party to the merger agreement of a breach of any provision thereunder will not operate or be construed as a waiver of any prior or subsequent breach of the same or any other provision thereunder.

Specific Performance; Third-Party Beneficiaries

Specific Performance

The parties to the merger agreement agreed that irreparable damage would occur in the event that any of the provisions of the merger agreement were not performed in accordance with its specific terms or if the merger agreement was otherwise breached and that monetary damages, even if available, would not be an adequate remedy thereunder. The parties are entitled to an injunction or injunctions

211

Table of Contents

to prevent breaches of the merger agreement and to enforce specifically the terms and provisions thereof in any Delaware court without proof of actual damages and each party to the merger agreement waives any requirement for the securing or posting of any bond in connection with such remedy. The parties to the merger agreement further agreed not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to applicable law or in equity for any reason, nor to assert that a remedy of monetary damages would provide an adequate remedy for such breach.

Third-Party Beneficiaries

Nothing in the merger agreement (other than the indemnification of directors and officers), expressed or implied, is intended to confer on any person other than the parties to the merger agreement or their respective successors and permitted assigns any rights, remedies, obligations or liabilities under or by reason of the merger agreement.

In connection with the signing of the merger agreement, Sonus, New Solstice, GB, GB II and certain investment funds affiliated with GENBAND, GB and GB II (which we refer to as the GENBAND equityholders) entered into a voting agreement, pursuant to which the GENBAND equityholders have agreed not to (subject to limited exceptions) sell or transfer any of their GENBAND shares, GB common stock or GB II common stock or effect a distribution of such stock and to vote all of their shares of such stock in a manner so as to facilitate the consummation of the mergers.

In order to facilitate the consummation of the mergers, the GENBAND equityholders have agreed to vote to approve or deliver a written consent adopting the merger agreement promptly following its receipt of this joint proxy statement/prospectus and, at any meeting of GENBAND shareholders, GB stockholders or GB II stockholders, to vote all of its shares of GENBAND shares, GB common stock or GB II common stock, as the case may be, in favor of the adoption of the merger agreement, the GENBAND mergers and the other transactions contemplated by the merger agreement. The GENBAND equityholders are also subject to certain requirements under the voting agreement that require them to vote against (i) the approval or adoption of any proposal made in opposition to or in competition with the merger agreement and the other transactions contemplated by the merger agreement and (ii) any other action that is intended, or would reasonably be expected, to impede, interfere with, delay, postpone discourage or adversely affect the consummation of the transactions contemplated by the merger agreement.

In addition, each GENBAND equityholder has agreed that until the earlier of the termination of the merger agreement or the effective time of the mergers, it will not, with respect to the GENBAND shares, GB common stock or GB II common stock:

•
  deposit any such stock into a voting trust or enter into a voting agreement or arrangement with respect to such stock; or
•
  grant any proxy or power of attorney with respect to such stock.

In connection with its agreements and obligations under the voting agreement, each GENBAND equityholder has also appointed Sonus, New Solstice and each of their respective executive officers or other designees with an irrevocable proxy with full power of attorney to vote in favor of the GENBAND mergers with respect to any GENBAND shares, GB common stock or GB II common stock owned by such GENBAND equityholder.

The voting agreement will terminate upon the earlier of such date and time as the voting agreement is terminated by mutual consent of the parties thereto, the effective time of the GENBAND mergers or such date and time as the merger agreement is validly terminated pursuant to the merger agreement.

Principal Stockholders Agreement

The following is a summary of certain material terms and provisions of the stockholders agreement. This summary does not purport to describe all of the terms and provisions of the stockholders agreement and is qualified in its entirety by the complete text of the stockholders agreement, a form of which is included as Annex I of this joint proxy statement/prospectus and incorporated by reference herein. All stockholders and shareholders (as applicable) of Sonus, GENBAND, GB and GB II are urged to read the stockholders agreement carefully and in its entirety, as well as this joint proxy statement/prospectus, before making any decisions regarding the merger agreement and the transactions contemplated thereby, including the mergers.

The merger agreement contemplates, as a condition to the closing of the transactions contemplated thereby, that at the closing, New Solstice will enter into a stockholders agreement with certain of the existing principal shareholders of GENBAND (which we refer to as the OEP Stockholders). The stockholders agreement becomes effective upon the closing of the transactions contemplated by the merger agreement and sets forth certain arrangements and contains various provisions relating to, among other things, board representation, standstill restrictions and transfer restrictions as further described below.

For purposes of the stockholders agreement, "independent director" means a person nominated or serving as a director of the New Solstice board who: (i) is independent for purposes of NASDAQ and SEC rules; (ii) does not then serve and has not served as a director, officer, partner or other senior-level employee (or other employee or consultant within the prior five years) of, and does not otherwise then receive (and has not at any time otherwise received) any material compensation from, any OEP Stockholder or any of its affiliates; and (iii) does not then serve (and has not at any time within the prior two years served) as a director, officer, employee or consultant of, and does not otherwise then receive (and has not at any time within the prior two years otherwise received) any compensation from, any portfolio company of any OEP Stockholder or any of its affiliates or any other third party that owns 15% or more of the issued and outstanding shares of New Solstice. Certain qualifications and exclusions apply to the foregoing definition, and the nominating and corporate governance committee of the New Solstice board may waive certain of the foregoing independent director requirements in certain circumstances.

Board Representation

The stockholders agreement will provide that the New Solstice board will be comprised of nine directors, subject to the following:

•
  for so long as the OEP Stockholders beneficially own at least 80% of the shares of New Solstice common stock beneficially owned in the aggregate on the date of the stockholders agreement, the OEP Stockholders will have the right to nominate five New Solstice board members, of which at least two must be independent directors;
•
  from and after the first time that the OEP Stockholders beneficially own less than 80% of the shares of New Solstice common stock beneficially owned in the aggregate on the date of the stockholders agreement, the number of directors that the OEP Stockholders will have the right to nominate will be reduced to four New Solstice board members, of which at least one must be an independent director;
•
  from and after the first time that the OEP Stockholders beneficially own less than 70% of the shares of New Solstice common stock beneficially owned in the aggregate on the date of the stockholders agreement, the number of directors that the OEP Stockholders will have the right to nominate will be reduced to three New Solstice board members, of which at least one must be an independent director;

214

Table of Contents

•
  from and after the first time that the OEP Stockholders beneficially own less than 50% of the shares of New Solstice common stock beneficially owned in the aggregate on the date of the stockholders agreement, the number of directors that the OEP Stockholders will have the right to nominate will be reduced to two New Solstice board members, neither of whom need be an independent director;
•
  from and after the first time that the OEP Stockholders beneficially own less than 30% of the shares of New Solstice common stock beneficially owned in the aggregate on the date of the stockholders agreement, the number of directors that the OEP Stockholders will have the right to nominate will be reduced to one New Solstice board member, who does not need to be an independent director; and
•
  upon the first date that the OEP Stockholders beneficially own less than 10% of the shares of New Solstice common stock they beneficially owned as of the date of the stockholders agreement, the OEP Stockholders will have no board designation rights and New Solstice may require any designees of the OEP Stockholders to resign from the New Solstice board.

New Solstice will take all necessary actions within its control to include the OEP Stockholder nominees in the slate of nominees recommended by the New Solstice board for election of directors and to cause the stockholders of New Solstice to elect the OEP Stockholder nominees. In the event any New Solstice board member nominated by the OEP Stockholders resigns or is unable to serve, the OEP Stockholders will be entitled to designate a replacement director, subject to the conditions set forth in the stockholders agreement.

Following the closing of the transactions contemplated by the merger agreement, the New Solstice board will maintain an audit committee, a compensation committee, a nominating and corporate governance committee and an integration committee.

So long as at least one of the directors designated by the OEP Stockholders qualifies as an independent director, any such independent director (or, in the case of the integration committee, any director designated by the OEP Stockholders) will be eligible to be appointed and remain on each of the board committees then in existence (other than a committee that is to be composed solely of independent directors or a committee established to address conflicts with the OEP Stockholders). In addition, the nominating and corporate governance committee of New Solstice will be comprised of three directors, at least two of whom will not be directors designated by the OEP Stockholders, and one of whom is an OEP Stockholder director if such director qualifies as an independent director. The nominating and corporate governance committee will determine the size and membership of the other committees (subject to the requirements set forth in the stockholders agreement).

So long as the OEP Stockholders are entitled to designate at least a majority of the directors of the New Solstice board of directors, an OEP Stockholder director shall be the chairman of each of the compensation committee, nominating and corporate governance committee and the integration committee. No OEP Stockholder director will be entitled to serve on any committee if it would violate mandatory legal or listing requirements concerning that director's independence or qualifications to serve as a member of the New Solstice board.

Voting

So long as the OEP Stockholders have director nomination rights under the stockholders agreement, with respect to any proposal or resolution relating to the election of directors, each OEP Stockholder will take all necessary actions within its control to vote its shares either affirmatively in favor of such director nominees, or in the same proportion to all shares voted by other stockholders of New Solstice.

Standstill Restrictions

The stockholders agreement contains certain standstill provisions restricting the OEP Stockholders from acquiring (or seeking or making any proposal or offer with respect to acquiring) additional shares of New Solstice common stock or any security convertible into New Solstice common stock or any assets, indebtedness or businesses of New Solstice or any of its subsidiaries. Certain customary exclusions apply, and acquisitions of New Solstice common stock by the OEP Stockholders will be permitted in open market acquisitions during open trading windows, following the determination of a majority of the New Solstice independent directors not to cause New Solstice to repurchase a material amount of shares of New Solstice common stock during such trading window. These restrictions are subject to certain customary exclusions. The standstill restrictions apply from the date of the stockholders agreement until the earlier of the acquisition of New Solstice by a third party in a change of control transaction as discussed in further detail below and when the OEP Stockholders no longer have any rights to nominate or designate nominees to the New Solstice board.

Change of Control

Without the approval of a majority of the independent directors, no OEP Stockholder may enter into or affirmatively support any transaction resulting in a change of control of New Solstice in which any OEP Stockholder receives per share consideration as a holder of New Solstice common stock in excess of that to be received by other holders of New Solstice common stock.

Transfer Restrictions

For 180 days following the effective time of the mergers, no OEP Stockholder may transfer any shares of New Solstice common stock that it beneficially owns (except to a permitted transferee that agrees to hold shares subject to the terms of the stockholders agreement). Thereafter, until three years following the effective time of the mergers, except as otherwise approved by a majority of independent directors, no OEP Stockholder may transfer any shares of New Solstice common stock that it beneficially owns if such transfer involves more than 15% of the outstanding shares of New Solstice common stock or if the transferee would own 15% of the outstanding shares of New Solstice common stock following such transfer, unless the transferee agrees to be subject to the stockholders agreement.

Termination

The stockholders agreement will terminate by mutual consent of a majority in interest of the OEP Stockholders and New Solstice (including the approval by a majority of independent directors) or when the OEP Stockholders, in the aggregate, beneficially own less than 2% of the New Solstice common stock.

Registration Rights Agreement

The following is a summary of certain material terms and provisions of the registration rights agreement. This summary does not purport to describe all of the terms and provisions of the registration rights agreement and is qualified in its entirety by the complete text of the registration rights agreement, a form of which is included as Annex J of this joint proxy statement/prospectus and incorporated by reference herein. All stockholders and shareholders (as applicable) of Sonus, GENBAND, GB and GB II are urged to read the registration rights agreement carefully and in its entirety, as well as this joint proxy statement/prospectus, before making any decisions regarding the merger agreement and the transactions contemplated thereby, including the mergers.

The merger agreement contemplates, as a condition to the closing of the transactions contemplated thereby, that at the closing, New Solstice will enter into a registration rights agreement with certain OEP Stockholders (which we refer to as the registration rights agreement). Under the

216

Table of Contents

registration rights agreement, certain OEP Stockholders will be granted certain registration rights beginning on the 180th day following the effective time of the mergers, including (i) the right to request that New Solstice file an automatic shelf registration statement and effect unlimited underwritten offerings pursuant to such shelf registration statement; (ii) unlimited demand registrations; and (iii) unlimited piggyback registration rights that allow holders of registrable shares to require that shares of New Solstice common stock owned by such holders be included in certain registration statements filed by New Solstice, in each case subject to the transfer restrictions contained in the stockholders agreement. In connection with these registration rights, New Solstice has agreed to effect certain procedural actions, including taking certain actions to properly effect any registration statement or offering and to keep the participating OEP Stockholders reasonably informed with adequate opportunity to comment and review, as well as customary indemnification and contribution agreements.

The Promissory Note

The following is a summary of certain material terms and provisions of the promissory note. This summary does not purport to describe all of the terms and provisions of the promissory note and is qualified in its entirety by the complete text of the promissory note, a form of which is included as Annex K of this joint proxy statement/prospectus and incorporated by reference herein. All stockholders and shareholders (as applicable) of Sonus, GENBAND, GB and GB II are urged to read the promissory note carefully and in its entirety, as well as this joint proxy statement/prospectus, before making any decisions regarding the merger agreement and the transactions contemplated thereby, including the mergers.

The merger agreement provides that, as a portion of the consideration for the GENBAND merger, New Solstice will pay to GENBAND shareholders, other than GB and GB II, interest and principal pursuant to a $22,500,000 promissory note in the form attached to the merger agreement as Exhibit D (which we refer to as the promissory note). The promissory note does not amortize and the principal thereon is payable in full on the third anniversary of its execution. Interest on the promissory note is payable quarterly in arrears and accrues at a rate of 7.5% per annum for the first six months after issuance, and thereafter at a rate of 10% per annum. The failure to make any payment under the promissory note when due and, with respect to payment of any interest, the continuation of such failure for a period of thirty days thereafter, constitutes an event of default under the promissory note. If an event of default occurs under the promissory note, the payees may declare the entire balance of the promissory note due and payable (including principal and accrued and unpaid interest) within five business days of the payees' notification to New Solstice of such acceleration.

Critical Accounting Policies and Estimates

Management's discussion and analysis of the financial condition and results of operations is based upon GENBAND's consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires GENBAND to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. GENBAND bases its estimates and judgments on historical experience, knowledge of current conditions and beliefs of what could occur in the future given available information. GENBAND considers the following accounting policies to be both those most important to the portrayal of its financial condition and those that require the most subjective judgment. If actual results differ significantly from management's estimates and projections, there could be a material effect on GENBAND's consolidated financial statements. The significant accounting policies that GENBAND believes are the most critical include the following:

•
  Foreign currency translation;

222

Table of Contents

•
  Revenue recognition;
•
  Deferred revenue;
•
  Deferred costs;
•
  Goodwill and intangible assets;
•
  Inventory;
•
  Income taxes;
•
  Defined benefits plans; and
•
  Share-based compensation.

Foreign Currency Translation. GENBAND's consolidated financial statements are presented in U.S. dollars (which we refer to as USD). GENBAND has reviewed the functional currency for all international operations in order to evaluate the appropriate functional currency for each location. This determination was made by assessing each of the foreign entities and the nature of its operations. After evaluating the relevant economic factors, GENBAND concluded that the operations in each of its foreign locations are relatively self-contained and integrated within their own particular country or economic environment, thus leading to the conclusion that the local currency should also be the functional currency. All foreign currency statements are translated from their functional currency into USD at the exchange rates in effect at the balance sheet dates for all assets and liabilities and at average rates for all revenues and expenses. The unrealized gains and losses on the net investment in these foreign operations are accumulated as a component of accumulated other comprehensive loss.

Revenue Recognition. GENBAND derives revenue from the sales of telecommunications hardware and software products, complex customized solutions and services, including post-contractual support, maintenance, installation and training that are generally sold pursuant to a contract. The terms of the contracts, taken as a whole, determine the appropriate revenue recognition models to be applied. Product revenue includes revenue from arrangements with software related services such as engineering, where the services cannot be separated from the arrangement because the services are essential or fair value cannot be established under the software revenue recognition guidance. In addition, product revenue includes all amounts billed to customers related to shipping and handling with the related expense as a component of cost of revenue in the accompanying consolidated statements of operations. Where services are sold stand-alone or can be separated from product sales in a bundled arrangement, service revenue is reported separately in the consolidated statements of operations.

GENBAND primarily derives subscription revenue from fees received from customers for time-based license arrangements and CPaaS offerings. GENBAND generally invoices subscription agreements in advance over the subscription period. Subscription revenue is generally recognized ratably over the subscription term when all revenue recognition criteria have been met and is included in product revenue in the consolidated statements of operations.

GENBAND makes significant judgments and estimates to determine revenue to be recognized in any accounting period. Material differences may result in the amount and timing of revenue for any period if GENBAND makes different judgments or utilizes different estimates. These estimates affect unbilled accounts receivable and deferred revenue in the consolidated balance sheets and total revenue

223

Table of Contents

in the consolidated statements of operations. In making these judgments, GENBAND uses the following assumptions and estimates:

Persuasive evidence of an arrangement. GENBAND considers a non-cancellable executed agreement (such as a customer purchase order, contract, etc.) or a group of closely-related agreements signed by all parties involved to be persuasive evidence of an arrangement.

Delivery has occurred. GENBAND generally considers delivery to have occurred when title to and the risk of loss of the products has passed to the customer and no post-delivery obligations exist, except for support. In instances where there are post-delivery obligations, delivery is deemed to occur when the customer specifications have been met with customer acceptance or delivery of the additional elements has occurred. For arrangements where the criteria for revenue recognition have not been met because legal title or risk of loss on products does not transfer to the customer until final payment has been received or where delivery has not occurred, revenue is deferred to a later period when the outstanding criteria have been met.

Fees are fixed or determinable. GENBAND assesses whether fees are fixed or determinable at the time of sale. GENBAND considers the fee to be fixed or determinable if the fees are due within GENBAND's standard payment terms and the fees are not subject to refund or adjustment. If the arrangement fees are not fixed or determinable, including arrangements with extended payment terms, revenue is recognized as cash is collected.

Collection is probable. GENBAND evaluates credit worthiness for all customers with significant transactions at the time of the transaction. Collection is deemed probable if GENBAND expects that the customer will be able to pay amounts under the arrangement as payments become due. If GENBAND determines that collection is not probable, revenue is deferred and recognized upon cash collection.

Depending on the terms of the contract and types of products and services sold, GENBAND recognizes revenue following the guidance for multiple-element arrangements and software revenue recognition in addition to the general revenue recognition guidance. Revenues are reduced for returns, allowances, discounts and other offerings in accordance with the agreement terms.

For multiple-element arrangements, GENBAND separates deliverables into more than one unit of accounting if the delivered item(s) have value to the customer on a stand-alone basis, and delivery of the undelivered item(s) is probable and substantially in GENBAND's control.

GENBAND determines the selling price for each deliverable based upon the selling price hierarchy for multiple-deliverable arrangements. Under this hierarchy, the selling price for each deliverable is determined using vendor specific objective evidence (which we refer to as VSOE) of selling price, if it exists; otherwise selling price is determined based on third-party evidence (which we refer to as TPE) of selling price. If neither VSOE nor TPE of selling price exist, GENBAND uses its best estimate of selling price (which we refer to as BESP) for that deliverable.

VSOE is established by the price charged when the item is sold separately on a stand-alone basis or based on the contractual renewal provision. GENBAND has VSOE for some, but not all, offerings. In cases where VSOE does not exist, GENBAND has been unable to establish TPE of selling price because there are relatively few observable competitor transactions along with varying levels of customization of products that make it difficult to compare to competitors' products and services. In determining BESP, GENBAND considers market conditions as well as entity-specific factors which include the impact to pricing based on geography, the pricing and profit objectives by customer class and region, consideration of any customization needed, the expected technological life, instances or probability of selling the product/service on a stand-alone basis and the use of third parties, among other factors.

Table of Contents

For arrangements without significant customization and where hardware and software components together provide the product's essential functionality, GENBAND recognizes revenue allocated to delivered items that are not contingent on the future delivery of products, services or other performance obligations, including where customer-specified return or refund privileges exist. Once GENBAND allocates revenue to each deliverable, GENBAND recognizes revenue in accordance with its revenue recognition policy noted herein.

For sales of software and software-related services, GENBAND generally uses the residual method to allocate the arrangement consideration. Under the residual method, the amount of consideration allocated to the delivered items equals the total value of software deliverables less the fair value of the undelivered items. For software arrangements where fair value does not exist for any undelivered item, revenue is not recognized until the earlier of (i) delivery of such item or (ii) when fair value of the undelivered item is established, unless the undelivered item is a service, in which case revenue is recognized as the service is performed under the cumulative catch-up method once the service is the remaining undelivered item.

Service elements are generally recognized according to the proportional performance method. The proportional performance method is used when the provision of services extends beyond an accounting period with more than one performance act, and permits the recognition of revenue ratably over the service period when no other pattern of performance is discernible. The nature of the service contract is reviewed to determine which revenue recognition method best reflects the nature of services performed. Provided all other revenue recognition criteria have been met, the revenue recognition method selected reflects the pattern in which the obligations to the customers have been fulfilled.

Deferred Revenue. Deferred revenue in the consolidated balance sheets generally consists of post-contract customer support (which we refer to as PCS) services that are deferred and recognized over the support term and revenue transactions that have outstanding deliverables. Deferred revenue which is not expected to be recognized over the next 12 months is classified as deferred revenue, net of current portion, in the consolidated balance sheets.

Deferred Costs. GENBAND defers costs for all customer sales arrangements in which there is a deferral of revenue recognition. Deferred costs consist of direct and associated costs related to the arrangement, such as the cost of the hardware, installation costs, third-party costs and other direct costs associated with the revenue. These costs are deferred up to the fair value of the products or services being sold and are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.

Goodwill and Intangible Assets. Business combinations have been accounted for using the acquisition method. Accordingly, GENBAND records the assets acquired and liabilities assumed in business combinations at their respective fair values at the date of acquisition, with any excess purchase price recorded as goodwill. This method also requires, among other things, expensing acquisition and integration costs, capitalization of in-process research and development separate from goodwill at the acquisition date fair value, and accounting for acquisition-related restructuring cost accruals subsequent to the acquisition date. The valuation of intangible assets requires significant estimates and assumptions including, but not limited to, determining the timing and expected costs to complete development projects, estimating future cash flows from product sales, developing appropriate discount rates, estimating probability rates for the successful completion of development projects, continuation of customer relationships and renewal of customer contracts and approximating the useful lives of the intangible assets acquired. Intangible assets, other than goodwill, are generally amortized based on the expected pattern of benefit to future periods using estimates of undiscounted cash flows or on a straight-line basis.

225

Table of Contents

Goodwill has an indefinite useful life and is not amortized, but is evaluated for impairment at the reporting unit level annually, on October 1, or whenever events or changes in circumstances indicate the carrying value may not be fully recoverable. In evaluating whether goodwill is impaired, GENBAND may first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. If it is determined the two-step quantitative test is necessary, the fair value of the reporting unit to which the goodwill is assigned is compared to the reporting unit's carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill is not considered impaired. If the carrying amount of the reporting unit exceeds its fair value, the second step of the goodwill impairment test is performed to measure the amount of impairment loss, if any. The second step of the goodwill impairment test compares the implied fair value of the reporting unit's goodwill with the carrying amount of that goodwill. The implied fair value of goodwill is determined by performing an assumed purchase price allocation, using the reporting unit fair value (as determined in the first step) as the purchase price. If the carrying amount of goodwill exceeds the implied fair value, an impairment loss is recognized in an amount equal to that excess. Determining the fair value of reporting units requires management to make a number of judgments about assumptions and estimates that are highly subjective and that are based on unobservable inputs. The actual results may differ from these assumptions and estimates, and it is possible that such differences could have a material impact on GENBAND's consolidated financial statements.

Long-lived assets, including intangible assets other than goodwill, are evaluated for impairment whenever events or changes in circumstances indicate that the net book value of an asset may not be fully recoverable. When such qualitative factors and circumstances exist, GENBAND compares the projected undiscounted future cash flows associated with related groups of assets over their estimated useful lives against their respective carrying amounts. Impairment, if any, is based on the excess of the carrying amount over the fair value of those assets and is recorded in the period in which the determination was made. GENBAND's estimate of future cash flows requires significant judgments and assumptions which may vary from actual cash flows.

Inventory. Inventory is valued at lower of cost or market. Cost is determined using standard cost, which approximates actual cost on a first-in, first-out basis. On an ongoing basis, inventory is reviewed and written down for estimated obsolescence or unmarketable inventory equal to the difference between the costs of inventory and the estimated net realizable value based upon forecasts for future customer demand and market conditions. Any adjustment to inventory as a result of an estimated obsolescence or net realizable condition is reflected as a component of cost of revenue. At the point of the loss recognition, a new, lower-cost basis for the respective inventory is established, and any subsequent improvements in facts and circumstances do not result in the restoration or increase to create a newly established cost basis.

Income Taxes. GENBAND accounts for income taxes under the asset and liability method prescribed by accounting guidance. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. GENBAND periodically assesses the recoverability of its deferred tax assets based upon expected future earnings, future deductibility of the asset, and changes in applicable tax laws and other factors. If GENBAND determines that it is more likely than not that the deferred tax asset will not be fully recoverable against future taxable income, a valuation allowance may be established for the difference between the asset balance and the amount expected to be recoverable in the future. The allowance will result in a charge to GENBAND's consolidated statements of operations. Further, GENBAND records its income taxes receivable and payable based upon its estimated income tax liability.

GENBAND accounts for uncertain tax positions, if any, utilizing the two-step approach. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence

226

Table of Contents

indicates that it is more likely than not the position will be sustained on audit based on the technical merits of the position. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. A liability is recorded (or a tax-related asset is reduced) for the unrecognized tax benefits when a tax position does not meet these criteria. GENBAND recognizes interest income, interest expense and penalties related to unrecognized tax benefits in income tax provision (benefit) in the consolidated statements of operations.

Defined Benefit Plans. GENBAND recognizes retirement benefit assets or liabilities in the consolidated balance sheets reflecting the funded status of pension and other retirement benefit plans. Retirement benefit assets and liabilities are adjusted for the difference between the benefit obligations and the plan assets at fair value (measured at year end), with the offset recorded directly in stockholders' deficit through accumulated other comprehensive loss, net of tax. The amount recorded in stockholders' deficit represents the after-tax unamortized actuarial gains or losses, unamortized transition obligations and unamortized prior service costs.

Share-Based Compensation. GENBAND measures and recognizes compensation expense for share-based awards based on estimated fair values on the date of grant using the Black-Scholes option-pricing model. This model is affected by GENBAND's calculated stock price as well as estimates regarding a number of variables, including expected stock price volatility over the expected term of the award. Compensation expense for these awards is measured and recognized as wages and benefits in the consolidated statements of operations on a straight-line basis over the vesting period.

Product revenue is comprised of sales of GENBAND's telecommunications hardware and software products. Product revenue in the three months ended June 30, 2017 was lower compared with the three months ended June 30, 2016 primarily as a result of a decrease in sales of GENBAND's Network Modernization portfolio. While the timing of the completion of customer projects, revenue recognition criteria satisfaction and customer payments included in multiple-element arrangements may cause GENBAND's product revenue to fluctuate from one period to the next, challenging market conditions persisted during the second quarter of 2017 resulting in less demand for certain network modernization products.

227

Table of Contents

The decrease in product revenue in the six months ended June 30, 2017 compared with the six months ended June 30, 2016 was in line with GENBAND's expectations and primarily the result of a decrease in sales of its Network Modernization portfolio. Challenging market conditions persisted, resulting in lower demand for these products compared with the corresponding period in 2016. GENBAND expects these market conditions to prevail in the second half of 2017.

Service revenue is comprised of all aspects of implementation and support of GENBAND's solutions and products. GENBAND's managed care services include hardware and software maintenance and support (which we refer to as GENBANDCare or GBCare) and solution and business consulting, system integration, and deployment (which we refer to as Professional Services).

Service revenue for the three and six months ended June 30, 2017 and 2016 was comprised of the following (in thousands, except percentages):

GENBANDCare revenue decreased in the three and six months ended June 30, 2017 compared with the three and six months ended June 30, 2016. GENBAND continues to operate in a market dominated by competitive pricing pressure where its customers may demand lower market pricing for legacy product support and could possibly decommission installed legacy products at certain customer sites. GENBAND's strategy is to address these market pressures by growing its maintenance support from new product sales.

The increase in GENBAND's Professional Services revenue in the three and six months ended June 30, 2017 compared with corresponding periods in 2016 was primarily due to greater project completions in 2017 compared with 2016.

The timing of the completion of projects for revenue recognition, customer payments and GENBANDCare contracts may cause GENBAND's service revenue to fluctuate from one period to the next.

GENBAND had two customers that represented 10% or more of GENBAND's revenue in the three months ended June 30, 2017 and 2016. Verizon Communications, Inc. represented 19% and 21% and AT&T, Inc. represented 11% and 11% of revenue for the three months ended June 30, 2017 and 2016, respectively.

These same two customers represented 10% or more of GENBAND's revenue in the six months ended June 30, 2017 and 2016. Verizon Communications, Inc. represented 16% and 18% and AT&T, Inc. represented 10% and 13% of revenue for the six months ended June 30, 2017 and 2016, respectively.

Revenue earned in the U.S. was approximately 52% and 54% of total revenue in the three months ended June 30, 2017 and 2016, respectively, and revenue earned outside the U.S. was approximately 48% and 46% of total revenue in the three months ended June 30, 2017 and 2016, respectively.

Revenue earned in the U.S. was approximately 50% and 54% of total revenue in the six months ended June 30, 2017 and 2016, respectively, and revenue earned outside the U.S. was approximately 50% and 46% of total revenue in the six months ended June 30, 2017 and 2016, respectively.

Due to the timing of project completions, it is reasonable to expect that revenue earned in the U.S. and internationally as a percentage of GENBAND's consolidated total revenue may fluctuate from quarter to quarter and year to year.

Cost of Revenue/Gross Margin. GENBAND's consolidated cost of revenue primarily consists of amounts paid to third-party manufacturers for purchased materials and services, royalties, manufacturing and professional services personnel and related costs, provision for inventory obsolescence and amortization of acquired technology.

GENBAND's consolidated cost of revenue and gross margins for the three and six months ended June 30, 2017 and 2016 were as follows (in thousands, except percentages):

Table of Contents

The decrease in service gross margin in the three and six months ended June 30, 2017 compared to the three and six months ended June 30, 2016 was primarily due to higher Professional Services revenue which has higher performance costs than GBCare revenues.

Research and Development Expense. Consolidated research and development expense consists primarily of salaries and related personnel costs, occupancy costs, consulting costs and the cost of development equipment and supplies for the design, development of new product software, improvement of existing products, process improvement and product use technologies. Research and development expenses for the three and six months ended June 30, 2017 and 2016 were as follows (in thousands, except percentages):

|  |  |  |  |  | Increase (decrease) from prior year |

The decrease in research and development expenses in the three months ended June 30, 2017 compared with the three months ended June 30, 2016 was primarily attributable to approximately $2 million of lower employee-related expenses, $1 million of lower product development costs from third-party engineering and $1 million of lower facilities-related expenses. The decrease in GENBAND's employee-related expenses was primarily attributable to lower third party labor costs due to its commitment to streamlining its operations and reducing its operating costs.

The decrease in research and development expenses in the six months ended June 30, 2017 compared with the six months ended June 30, 2016 was primarily attributable to approximately $3 million of lower employee-related expenses, $1 million of lower product development costs from third-party engineering, $1 million of lower facilities-related expenses and $1 million of lower combined costs equally contributable to depreciation expense and professional fees. The decrease in GENBAND's employee-related expenses was primarily attributable to lower third party labor costs due to its commitment to streamlining its operations and reducing its operating costs.

Some aspects of GENBAND's research and development efforts require significant short-term expenditures, the timing of which may cause significant variability in its expenses. GENBAND believes that rapid technological innovation is critical to its long-term success, and GENBAND is tailoring its investments to meet the requirements of its customers and market.

Sales and Marketing Expense. Consolidated sales and marketing expense consists primarily of salaries and related personnel costs, commissions, travel and entertainment expenses, promotions, and other marketing and sales support expenses. Sales and marketing expenses for the three and six months ended June 30, 2017 and 2016 were as follows (in thousands, except percentages):

|  |  |  |  |  | Increase (decrease) from prior year |

Six months ended |  | $ | 31,738 |  | $ | 34,276 |  |  | (2,538 | ) |  | –7.4 | %

The decrease in sales and marketing expenses in the three months ended June 30, 2017 compared with the three months ended June 30, 2016 was primarily due to $1 million of lower travel and entertainment costs, and $1 million of lower combined employee-related costs.

Table of Contents

The decrease in sales and marketing expenses in the six months ended June 30, 2017 compared with the six months ended June 30, 2016 arose from $1 million of lower employee-related expenses attributable to fewer employees due to GENBAND's commitment to streamlining its operations and reducing its operating costs, and over $1 million of lower combined costs equally contributable to value added taxes, bad debt expense and facility costs.

General and Administrative Expense. Consolidated general and administrative expense consists primarily of salaries and related personnel costs for administrative personnel, and legal, audit and other administrative professional fees. General and administrative expenses for the three and six months ended June 30, 2017 and 2016 were as follows (in thousands, except percentages):

|  |  |  |  |  | Increase (decrease) from prior year |

Six months ended |  | $ | 19,243 |  | $ | 18,305 |  |  | 938 |  |  | 5.1 | %

Consolidated general and administrative expense was relatively unchanged for the three months ended June 30, 2017 compared with the three months ended June 30, 2016.

The increase in general and administrative expenses in the six months ended June 30, 2017 compared with the six months ended June 30, 2016 principally arose from slight increases in amounts earned under GENBAND's bonus plans.

Legal Costs for Patent Litigation. Legal costs for patent litigation include the legal expenses incurred related to four lawsuits involving GENBAND and Metaswitch Networks Ltd., Metaswitch Networks Corp. and Metaswitch Inc. (which we refer to collectively as Metaswitch). The first complaint was filed by GENBAND on January 23, 2014 alleging that Metaswitch infringed certain patents owned by GENBAND. Following unsuccessful mediation, a trial took place, and a jury determined that GENBAND was entitled to approximately $8 million in past royalty damages on January 15, 2016. On September 29, 2016, the United States District Court for the Eastern District of Texas (which we refer to as the Federal District Court) entered judgment confirming the jury verdict, but denied GENBAND's request for a permanent injunction. GENBAND appealed the denial of its request for a permanent injunction and presented oral argument on this issue before the U.S. Court of Appeals for the Federal Circuit on June 8, 2017. On July 20, 2017, the U.S. Court of Appeals for the Federal Circuit vacated the lower court's denial of a permanent injunction and remanded the case for further consideration of GENBAND's request for a permanent injunction under the proper legal standard. GENBAND is seeking ongoing royalties and other damages in motions pending before the Federal District Court. Metaswitch has appealed the judgment, and GENBAND has appealed the denial of a permanent injunction. Due to the uncertainties surrounding the ultimate outcome, GENBAND did not recognize awards in the case as income in its financial statements for the three or six months ended June 30, 2017 or 2016.

A second lawsuit was filed on July 7, 2014, between GENBAND and Metaswitch in which both parties asserted further claims of patent infringement against each other. The trial for the second lawsuit concluded on March 17, 2016 with no damages awarded to either party. The court entered a final judgment on April 14, 2016 awarding GENBAND its costs as the prevailing party. GENBAND's motion for its costs is pending, as are the parties' motions for judgment as a matter of law and for a new trial.

On June 2, 2016, the Federal District Court issued an order removing a stay and consolidating various non-patent claims and counterclaims that were previously stayed/severed from the first two

231

lawsuits into a third lawsuit. On March 28, 2017, the Federal District Court dismissed this third lawsuit without prejudice for improper subject matter jurisdiction. Immediately following the dismissal of this Federal District Court action on March 28, 2017, GENBAND filed a petition against Metaswitch in the District Court of Dallas County, Texas (134th Judicial District) (which we refer to as the Texas State Court), asserting the claims GENBAND had previously asserted in the Federal District Court action. Metaswitch filed its answer on April 21, 2017 and asserted counterclaims against GENBAND. The Texas State Court issued a scheduling order setting trial for this case in April 2018. At this time, it is not possible to predict the outcome, including whether or not any proceedings will continue, and if so, when or how the matter will be resolved. Therefore, an estimate of the possible range of loss, if any, cannot be made.

Additionally, on March 29, 2017, Metaswitch filed a petition in Superior Court of the State of California, County of Santa Clara (which we refer to as the California State Court) seeking declaratory judgment regarding GENBAND's trade secret misappropriation claims previously asserted in the Federal District Court action that was dismissed. Metaswitch also asserts claims of common law unfair competition and tortious interference with a prospective business relationship against GENBAND. Metaswitch filed a request for dismissal of this case on June 29, 2017. GENBAND is waiting for a Dismissal Order from the California State Court to consider the matter closed.

Acquisition and Integration Expense. Consolidated acquisition and integration expense includes costs related to business acquisitions that would not otherwise have been incurred. These expenses include professional and other service fees. GENBAND recorded $4 million of these expenses in the three and six months ended June 30, 2017 in connection with the proposed merger with Sonus Networks, Inc. No such expenses were recorded by GENBAND in the three and six months ended June 30, 2016.

Restructuring Expense. During 2017 and 2016, GENBAND committed itself to streamlining its operations and reducing its operating costs to better correspond with market conditions. To better align its cost structure, restructuring initiatives have been implemented to close and consolidate certain facilities and reduce GENBAND's worldwide workforce, primarily in the research and development areas in the U.S., Canada, Europe, Asia and the Middle East. GENBAND's assessment of its operations is ongoing and may result in further restructuring and related charges, the amount and timing of which cannot be determined at this time.

GENBAND recorded $1 million of expense in each of the three and six month periods ended June 30, 2017 and 2016 in connection with restructuring initiatives, primarily for severance and related costs.

Although GENBAND has eliminated positions as part of its restructuring initiatives, it continues to hire in certain areas that it believes are strategic or are important to its future growth. Restructuring expense is reported separately in the consolidated statements of operations.

Amortization of Acquired Intangibles. Consolidated amortization of acquired intangibles results from intangible assets identified in GENBAND's business combinations, which occurred primarily from

2010 through 2014 and were accounted for using the acquisition method of accounting. GENBAND recorded amortization expense of approximately $1 million in each of the three months ended June 30, 2017 and 2016 and approximately $2 million in each of the six month periods ended June 30, 2017 and 2016. GENBAND anticipates that amortization expense will decrease in future periods as these assets gradually reach the end of their useful accounting lives.

Interest Expense. Interest expense includes the costs of interest, letters of credit and commitment fees associated with GENBAND's revolving credit facility and term debt, and amortization of debt issuance costs. GENBAND recorded about $1 million of interest expense in each of the three months ended June 30, 2017 and 2016, about $3 million of interest expense in the six months ended June 30, 2017 and $2 million of interest expense in the six months ended June 30, 2016. The slight increase in interest expense in the three and six months ended June 30, 2017 compared to the three and six months ended June 30, 2016 arose primarily from the quarterly compounding of interest required by GENBAND's 2016 Subordinated Term Loan Agreement (which we refer to as the Subordinated Term Loan) with OEP Parent LLC (which we refer to as OEP Parent), a related party.

Other Expense (Income), Net. Other expense (income), net includes (gain) loss on foreign currency exchange transactions and miscellaneous income and expense. Other expense (income), net for the three and six months ended June 30, 2017 and 2016 was as follows (in thousands, except percentages):

Income Taxes. GENBAND is classified as a partnership under U.S. federal tax law. No U.S. federal income tax (benefit) provision is included in GENBAND's consolidated financial statements related to the income or loss generated by GENBAND. Certain subsidiaries of GENBAND remain subject to U.S. federal and state income taxation due to their classification as a corporation under U.S. tax law. All of GENBAND's international subsidiaries are subject to tax in their respective jurisdictions.

GENBAND recorded a (benefit) provision for income taxes primarily related to its foreign operations of approximately $(2) million in the three months ended June 30, 2017 and $1 million in the three months ended June 30, 2016. The decrease in the income tax provision was primarily due to GENBAND's operating losses in Ireland.

GENBAND recorded a (benefit) for income taxes of approximately $(3) million in the six months ended June 30, 2017, primarily related to operating losses in Ireland. GENBAND recorded a provision for income taxes of approximately $2 million in the six months ended June 30, 2016, primarily related to foreign operations and U.S. non-partnership income. The decrease in 2017 was primarily the result of operating losses in Ireland.

Effects of Inflation. While inflation may impact its revenues and cost of services, GENBAND believes the effects of inflation, if any, on its results of operations and financial condition have not been significant. However, there can be no assurance that GENBAND's results of operations and financial condition will not be materially impacted by inflation in the future.

The increase in product revenue in 2016 compared with 2015 was primarily the result of an increase in sales of GENBAND's Network Modernization portfolio, which contributed higher product revenue in 2016 compared to 2015 of approximately $23 million.

The timing of the completion of customer projects, revenue recognition criteria satisfaction and customer payments included in multiple element arrangements may cause GENBAND's product revenue to fluctuate from one period to the next.

Service revenue for the years ended December 31, 2016 and 2015 was comprised of the following (in thousands, except percentages):

|  | Year Ended December 31, |  | Increase (decrease) from prior year |

GENBANDCare revenue decreased in 2016 compared to 2015. GENBAND continues to operate in a market dominated by competitive pricing pressure where its customers may demand lower market pricing for legacy product support and could possibly decommission installed legacy products at certain customer sites. GENBAND's strategy is to address these market pressures by growing its maintenance support from new product sales.

The decrease in GENBAND's Professional Services revenue in 2016 compared with 2015 was primarily due to a change in projects completion timing in 2016 compared to 2015. The timing of the completion of projects for revenue recognition, customer payments and GENBANDCare contracts may cause GENBAND's services revenue to fluctuate from one period to the next.

GENBAND had one customer that represented 10% or more of GENBAND's revenue in the years ended December 31, 2016 and 2015. Verizon Communications, Inc. represented 22% and 18% of revenue for the years ended December 31, 2016 and 2015, respectively.

Revenue earned in the U.S. was approximately 56% and 54% of total revenue in 2016 and 2015, respectively, and revenue earned outside the U.S. was approximately 44% and 46% of total revenue in 2016 and 2015, respectively. Due to the timing of project completions, it is reasonable to expect that

revenue earned in the U.S. and internationally as a percentage of GENBAND's consolidated total revenue may fluctuate from quarter to quarter and year to year.

Cost of Revenue/Gross Margin. GENBAND's consolidated cost of revenue and gross margins for the years ended December 31, 2016 and 2015 were as follows (in thousands, except percentages):

Total gross margin |  |  | 50.2 | % |  | 45.9 | % |  |  |  |  |  |

The increase in product gross margin in 2016 compared with 2015 was primarily due to higher product revenue against certain fixed manufacturing costs and the result of focused efforts to improve GENBAND's cost of product structure.

The increase in service gross margin in 2016 compared with 2015 was primarily attributable to an improved services cost structure due to GENBAND's commitment to streamlining its operations and reducing its operating costs.

Research and Development Expense. Research and development expenses for the years ended December 31, 2016 and 2015 were as follows (in thousands, except percentages):

|  | Year ended December 31, |  | Increase (decrease) from prior year |
--- | --- | --- | --- | --- | ---
|  | 2016 |  | 2015 |  | $ |  | % |
Research and development |  | $ | 102,162 |  | $ | 119,444 |  | $ | (17,282 | ) |  | –14.5 | %

The decrease in research and development expenses in 2016 compared with 2015 was attributable to approximately $9 million of lower employee-related expenses, $4 million of lower product development costs from third-party engineering, a $2 million increase in the capitalization of CPaaS development costs, $1 million of lower facilities-related expenses and $1 million of lower depreciation expense. The decrease in GENBAND's employee-related expenses was attributable to $5 million of lower contract labor and $4 million related to fewer employees, both due to its commitment to streamlining its operations and reducing its operating costs.

Some aspects of GENBAND's research and development efforts require significant short-term expenditures, the timing of which may cause significant variability in its expenses. GENBAND believes that rapid technological innovation is critical to its long-term success and is tailoring its investments to meet the requirements of its customers and market.

Sales and Marketing Expense. Sales and marketing expenses for the years ended December 31, 2016 and 2015 were as follows (in thousands, except percentages):

|  | Year ended December 31, |  | Increase (decrease) from prior year |
--- | --- | --- | --- | --- | ---
|  | 2016 |  | 2015 |  | $ |  | % |
Sales and marketing |  | $ | 69,744 |  | $ | 86,737 |  | $ | (16,993 | ) |  | –19.6 | %

The decrease in sales and marketing expenses in 2016 compared with 2015 arose from approximately $10 million of lower employee-related expenses attributable to fewer employees due to GENBAND's commitment to streamlining its operations and reducing its operating costs, $4 million of lower travel and entertainment costs and $1 million of lower facility costs.

General and Administrative Expense. General and administrative expenses for the years ended December 31, 2016 and 2015 were as follows (in thousands, except percentages):

|  | Year ended December 31, |  | Increase (decrease) from prior year |
--- | --- | --- | --- | --- | ---
|  | 2016 |  | 2015 |  | $ |  | % |
General and administrative |  | $ | 36,810 |  | $ | 38,245 |  | $ | (1,435 | ) |  | –3.8 | %

The decrease in general and administrative expenses in 2016 compared with 2015 principally arose from lower depreciation expense of approximately $4 million and a reduction in professional fees of $2 million, partially offset by higher employee-related and facilities-related expenses of approximately $4 million and $2 million, respectively. The increase in employee-related expenses was attributable to increased amounts earned under GENBAND's bonus plans, partially offset by nearly $2 million of lower salaries and related expenses arising from fewer general and administrative employees due to GENBAND's commitment to streamlining its operations and reducing its operating costs.

Legal Costs for Patent Litigation. Legal costs for patent litigation include the legal expenses incurred related to four lawsuits involving GENBAND and Metaswitch as discussed under "Legal Costs for Patent Litigation" under "Results of Operations"—"Three and Six Months Ended June 30, 2017 and June 30, 2016" above. Legal costs for patent litigation for the years ended December 31, 2016 and 2015 were as follows (in thousands, except percentages):

|  | Year ended December 31, |  | Increase (decrease) from prior year |
--- | --- | --- | --- | --- | ---
|  | 2016 |  | 2015 |  | $ |  | % |
Legal costs for patent litigation |  | $ | 11,391 |  | $ | 22,223 |  | $ | (10,832 | ) |  | –48.7 | %

Revaluation of contingent consideration. In 2015, GENBAND revalued a contingent consideration liability, resulting in operating income of nearly $3 million. This contingent consideration relates to the 2014 acquisition of uReach Technologies, Inc., that GENBAND revalued from a fair value of $3.8 million at the date of acquisition to a fair value of $0.6 million. This contingent consideration is being paid quarterly, and equates to 17.5% of cash collected on sales of the CSF Platform to a specific customer through March 31, 2017, based on purchase orders dated through December 31, 2016.

Acquisition and Integration Expense. Consolidated acquisition and integration expense includes costs related to business acquisitions that would not otherwise have been incurred. These expenses include professional and other service fees. GENBAND recorded less than $0.1 million of these expenses in 2016 and recorded $2 million of acquisition-related expenses in 2015 in connection with prior years' acquisitions, including the acquisitions of uReach Technologies, Inc. and Ventraq, Inc. in 2014 and 2013, respectively.

Restructuring Expense. During 2016 and 2015, GENBAND committed itself to streamlining its operations and reducing its operating costs to better correspond with market conditions. To better align its cost structure, restructuring initiatives have been implemented to close and consolidate certain facilities and reduce its worldwide workforce, primarily in the research and development areas in the U.S., Canada, Europe, Asia and the Middle East. GENBAND's assessment of its operations is ongoing and may result in further restructuring and related charges, the amount and timing of which cannot be determined at this time.

In late 2016, GENBAND's restructuring efforts continued and included an initiative to close a facility in EMEA, consolidate facilities and reduce its worldwide workforce by approximately 100 positions. Restructuring expense totaled approximately $7 million in 2016, comprised of $5 million for severance and related costs and $2 million for facilities-related costs.

GENBAND recorded approximately $10 million of expense in 2015 in connection with restructuring initiatives, comprised of about $9 million of expense for severance and related costs and $1 million for facilities-related costs due to the consolidation of facilities.

Although GENBAND has eliminated positions as part of its restructuring initiatives, it continues to hire in certain areas that it believes are strategic or are important to its future growth. Restructuring expense is reported separately in the consolidated statements of operations.

Amortization of Acquired Intangibles. GENBAND recorded amortization of acquired intangibles of nearly $5 million in 2016 and approximately $7 million in 2015. GENBAND anticipates that this amortization expense will decrease in future periods as these assets gradually reach the end of their useful accounting lives.

Interest Expense. GENBAND recorded about $5 million of interest expense in 2016 and $1 million of interest expense in 2015. Higher interest expense in 2016 arose primarily from the higher balance of, and the quarterly compounding of interest required under, its Subordinated Term Loan.

Other Expense (Income), Net. Other expense (income), net for the years ended December 31, 2016 and 2015 was as follows (in thousands, except percentages):

|  | Year Ended December 31, |  | Increase (decrease) from prior year |
--- | --- | --- | --- | --- | ---

Income Taxes. GENBAND is classified as a partnership under U.S. federal tax law. No U.S. federal income tax provision (benefit) is included in GENBAND's consolidated financial statements related to the income or loss generated by GENBAND. Certain subsidiaries of GENBAND remain subject to U.S. federal and state income taxation due to their classification as a corporation under U.S. federal tax law. All of GENBAND's international subsidiaries are subject to tax in their respective jurisdictions.

GENBAND recorded a provision for income taxes of $3 million in 2016, primarily related to foreign operations. GENBAND recorded a provision for income taxes of $4 million in 2015, primarily related to foreign operations and U.S. non-partnership income. The decrease in 2016 was primarily the result of lower non-partnership income in the U.S.

Effects of Inflation. While inflation may impact its revenues and cost of services, GENBAND believes the effects of inflation, if any, on its results of operations and financial condition have not been significant. However, there can be no assurance that its results of operations and financial condition will not be materially impacted by inflation in the future.

The decrease in product revenue in 2015 compared with 2014 was primarily the result of a decrease in sales of GENBAND's Network Modernization portfolio and the strengthening of the U.S. dollar relative to certain foreign currencies. While the timing of the completion of customer projects, revenue recognition criteria satisfaction and customer payments included in multiple-element arrangements may cause GENBAND's product revenue to fluctuate from one period to the next, challenging market conditions persisted during 2015 resulting in less demand for certain network modernization products. In addition, certain large purchases in 2014 by two significant customers of media gateway and transcoding capacity aggregating $40 million did not repeat in the 2015 financial period. The strengthening of the U.S. dollar had an approximately $10 million adverse effect on revenue in 2015 compared with 2014.

Service revenue for the years ended December 31, 2015 and 2014 was comprised of the following (in thousands, except percentages):

|  | Year Ended December 31, |  | Increase (decrease) from prior year |

GENBANDCare revenue decreased in 2015 compared with 2014. The strengthening of the U.S. dollar had an approximately $11 million adverse effect on revenue in 2015 as compared to 2014. GENBAND continues to operate in a market dominated by competitive pricing pressure where its customers may demand lower market pricing for legacy product support and could possibly decommission installed legacy products at certain customer sites. GENBAND's strategy is to address these market pressures by growing its maintenance support from new product sales.

The decrease in GENBAND's Professional Services revenue in 2015 compared with 2014 was primarily due to projects completion timing and the strengthening of the U.S. dollar relative to certain foreign currencies. Significant professional services were performed in 2014 for a Tier 1 U.S. service provider that did not accompany product sales. In addition, several non-recurring network transformation deployment projects were completed in 2014. The strengthening of the U.S. dollar had an approximately $4 million adverse effect on revenue in 2015 compared with 2014.

The timing of the completion of projects for revenue recognition, customer payments and GENBANDCare contracts may cause GENBAND's services revenue to fluctuate from one period to the next.

GENBAND had one customer that represented 10% or more of GENBAND's revenue for the year ended December 31, 2015 and two customers that represented 10% or more of GENBAND's revenue for the year ended December 31, 2014. Verizon Communications, Inc. represented 18% and 17% of revenue for the years ended December 31, 2015 and 2014, respectively. Alcatel-Lucent USA Inc. represented 11% of revenue for the year ended December 31, 2014.

Revenue earned in the U.S. was approximately 54% and 53% of total revenue in 2015 and 2014, respectively, and revenue earned outside the U.S. was approximately 46% and 47% of total revenue in 2015 and 2014, respectively. Due to the timing of project completions, it is reasonable to expect that revenue earned in the U.S. and internationally as a percentage of GENBAND's consolidated total revenue may fluctuate from quarter to quarter and year to year.

Cost of Revenue/Gross Margin. GENBAND's consolidated cost of revenue and gross margins for the years ended December 31, 2015 and 2014 were as follows (in thousands, except percentages):

Total gross margin |  |  | 45.9 | % |  | 44.6 | % |  |  |  |  |  |

The increase in product gross margin in 2015 compared to 2014 was primarily due to certain lower fixed manufacturing costs as a result of focused efforts to improve GENBAND's cost of product structure.

Research and Development Expense. Research and development expenses for the years ended December 31, 2015 and 2014 were as follows (in thousands, except percentages):

|  | Year Ended December 31, |  | Increase (decrease) from prior year |
--- | --- | --- | --- | --- | ---

Research and development |  | $ | 119,444 |  | $ | 128,179 |  | $ | (8,735 | ) |  | –6.8 | %

The decrease in research and development expenses in 2015 compared with 2014 was attributable to approximately $8 million of lower employee-related expenses and $1 million of lower facilities-related costs. The decrease in GENBAND's employee-related expenses was attributable to $5 million of lower 3rd party labor costs and $3 million related to fewer employees, both due to its commitment to streamlining its operations and reducing its operating costs.

Some aspects of GENBAND's research and development efforts require significant short-term expenditures, the timing of which may cause significant variability in its expenses. GENBAND believes

that rapid technological innovation is critical to its long-term success, and GENBAND is tailoring its investments to meet the requirements of its customers and market.

Sales and Marketing Expense. Sales and marketing expenses for the years ended December 31, 2015 and 2014 were as follows (in thousands, except percentages):

|  | Year Ended December 31, |  | Increase (decrease) from prior year |
--- | --- | --- | --- | --- | ---
|  | 2015 |  | 2014 |  | $ |  | % |
Sales and marketing |  | $ | 86,737 |  | $ | 91,795 |  | $ | (5,058 | ) |  | –5.5 | %

The decrease in sales and marketing expenses in 2015 compared with 2014 arose from approximately $5 million of lower employee-related expenses, $2 million of lower advertising and other marketing expenses, and $1 million of lower travel and entertainment costs. These decreases were partially offset by $2 million of higher bad debt expense. The decrease in employee-related expenses was attributable to fewer employees due to its commitment to streamlining its operations and reducing its operating costs.

General and Administrative Expense. General and administrative expenses for the years ended December 31, 2015 and 2014 were as follows (in thousands, except percentages):

|  | Year Ended December 31, |  | Increase (decrease) from prior year |
--- | --- | --- | --- | --- | ---
|  | 2015 |  | 2014 |  | $ |  | % |
General and administrative |  | $ | 38,245 |  | $ | 46,643 |  | $ | (8,398 | ) |  | –18.0 | %

The decrease in general and administrative expenses in 2015 compared with 2014 principally arose from approximately $9 million of lower employee-related expenses, nearly $2 million of lower depreciation expense and $1 million of lower travel and entertainment costs. These reductions were partially offset by nearly $2 million of higher facilities-related expenses. The decrease in employee-related expenses was attributable to approximately $6 million less earned under GENBAND's bonus plans, and $3 million of lower salaries and related expenses arising from fewer general and administrative employees due to GENBAND's commitment to streamlining its operations and reducing its operating costs.

Legal Costs for Patent Litigation. Legal costs for patent litigation include the legal expenses incurred related to the lawsuits involving GENBAND and Metaswitch as discussed under "Legal Costs for Patent Litigation" under "Results of Operations"—"Three and Six Months Ended June 30, 2017 and June 30, 2016" above. Legal costs for patent litigation for the years ended December 31, 2015 and 2014 were as follows (in thousands, except percentages):

Legal costs for patent litigation |  | $ | 22,223 |  | $ | 4,078 |  | $ | 18,145 |  |  | 445.0 | %

Revaluation of contingent consideration. In 2015, GENBAND revalued a contingent consideration liability, resulting in operating income of nearly $3 million. This contingent consideration relates to the 2014 acquisition of uReach Technologies, Inc., that GENBAND revalued from a fair value of $3.8 million at the date of acquisition to a fair value of $0.6 million. This contingent consideration was paid quarterly and equated to 17.5% of cash collected on sales of the CSF Platform to a specific customer through March 31, 2017, based on purchase orders dated through December 31, 2016.

Acquisition and Integration Expense. GENBAND recorded acquisition-related expenses in 2015 and 2014 of $2 million and $1 million, respectively, in connection with prior years' acquisitions, including the acquisitions of uReach Technologies, Inc. and Ventraq, Inc. in 2014 and 2013, respectively.

Restructuring Expense. During 2015 and 2014, GENBAND committed itself to streamlining its operations and reducing its operating costs to better correspond with market conditions. To better align its costs structure, restructuring initiatives have been implemented to close and consolidate certain facilities and reduce its worldwide workforce, primarily in the research and development areas in the U.S., Canada, Europe, Asia and the Middle East. GENBAND's assessment of its operations is ongoing and may result in further restructuring and related charges, the amount and timing of which cannot be determined at this time.

In 2015, GENBAND's restructuring efforts continued and included an initiative to consolidate facilities and reduce its worldwide workforce by approximately 100 positions. Restructuring expense totaled nearly $10 million in 2015, comprised of approximately $9 million of expense for severance and related costs and $1 million for facilities-related costs due to the consolidation of facilities.

GENBAND recorded restructuring expense aggregating $1 million in 2014, comprised almost entirely of severance and related costs.

Although GENBAND has eliminated positions as part of its restructuring initiatives, it continues to hire in certain areas that it believes are strategic or are important to its future growth. Restructuring expense is reported separately in the consolidated statements of operations.

Amortization of Acquired Intangibles. GENBAND recorded amortization of acquired intangibles of nearly $7 million in 2015 and $8 million in 2014. GENBAND anticipates that this amortization expense will decrease in future periods as these assets gradually reach the end of their useful accounting lives.

Interest Expense. GENBAND recorded over $1 million of interest expense in 2015 and nearly $1 million of interest expense in 2014. Higher interest expense in 2015 arose from the interest on borrowings under its Subordinated Term Loan agreement with a related party that was entered into in 2015.

Other Income, Net. Other income, net for the years ended December 31, 2015 and 2014 was as follows (in thousands, except percentages):

Income Taxes. GENBAND is classified as a partnership under U.S. federal tax law. No U.S. federal income tax provision (benefit) is included in GENBAND's consolidated financial statements related to the income or loss generated by GENBAND. Certain subsidiaries of GENBAND remain subject to U.S. federal and state income taxation due to their classification as a corporation under U.S. federal tax law. All of GENBAND's international subsidiaries are subject to tax in their respective jurisdictions.

GENBAND recorded a provision for income taxes of $4 million in 2015, primarily related to foreign operations and U.S. non-partnership income. GENBAND recorded a (benefit) for income taxes of nearly $(1) million in 2014 primarily related to foreign operations, offset by the release of tax reserves due to statute of limitations lapses. The increase in 2015 was primarily the result of higher U.S. non-partnership income and lower release of tax reserves compared to 2014.

GENBAND's cash and cash equivalents totaled approximately $22 million at June 30, 2017 and $33 million at December 31, 2016. As of June 30, 2017, GENBAND had long-term related party borrowings outstanding of $40 million and $19 million of borrowings outstanding under its revolving credit line. As of December 31, 2016, GENBAND had long-term related party borrowings outstanding of $40 million and $17 million was outstanding under its revolving credit line. GENBAND's revolving credit line outstanding balance and availability is subject to a Credit Agreement with Silicon Valley Bank (which we refer to as SVB), as lead agent, and has a term expiring July 1, 2019. The long-term related party debt is due on September 30, 2019 and is subordinate to the borrowings outstanding under the revolving line of credit.

Effective July 1, 2016, two of GENBAND's operating subsidiaries, with GENBAND as guarantor, entered into a Senior Secured Credit Agreement with SVB (which we refer to as the SVB Agreement). The SVB Agreement, with a maturity date of July 1, 2019, provides for revolving loans, including letters of credit, not to exceed $50 million in total, with a potential further increase available for a total revolving line of credit up to $75 million. Borrowing availability is determined monthly based on the amount of collateralized eligible trade accounts receivable. Both Alternate Base Rate (which we refer to as ABR) and Eurodollar loans are available under the facility. ABR loans bear interest based on the higher of the prime rate and the federal funds effective rate, plus 0.5% and an applicable margin that varies according to the amount of borrowings available. Eurodollar loans bear interest based on LIBOR plus an applicable margin that varies according to the amount of borrowings available. In the event of a default, the annual interest rates would increase by 2%.

The SVB Agreement requires GENBAND to comply with certain representations, warranties, periodic reporting and financial covenants, including maintaining a minimum free cash flow and

minimum liquidity. As of June 30, 2017, GENBAND was in compliance with all covenants related to the SVB Agreement.

As of June 30, 2017, GENBAND had $19 million of borrowings outstanding under the SVB Agreement. Letters of credit outstanding as of June 30, 2017 under the revolving credit line totaled approximately $2 million. The availability remaining under the revolving credit line was approximately $10 million as of June 30, 2017.

In 2016, GENBAND entered into the Subordinated Term Loan with OEP Parent, a related party. The Subordinated Term Loan bears interest at 10%, compounding quarterly, with a maturity date of September 30, 2019. As of June 30, 2017, there were borrowings outstanding of $40 million, with no additional available borrowing capacity. Borrowings under the Subordinated Term Loan are unsecured and are subordinate to GENBAND's revolving credit facility. No prepayment of the Subordinated Term Loan is allowed pursuant to the SVB Agreement until the SVB Agreement expires. Upon the occurrence of an Event of Default (as defined in the Subordinated Term Loan), the interest rate would increase to 12%.

Through June 30, 2016, GENBAND maintained a banking relationship with Comerica Bank that consisted of a $16 million, three-year term loan entered into during 2013 to effectuate an acquisition and a revolving credit facility. On June 30, 2016, the term loan matured, and the underlying credit facility, including the revolving credit facility, was terminated in lieu of entering into the SVB Agreement.

GENBAND had net cash flows used in operations of approximately $10 million in the six months ended June 30, 2017 compared with cash used in operations of approximately $17 million in the six months ended June 30, 2016. The increase in cash flows from operations in the 2017 period compared with the 2016 period of $7 million is primarily due to decreases in prepaid expenses and other current assets and a lower net loss as a result of operational efficiencies.

Cash used in operating activities in the six months ended June 30, 2017 was primarily the result of decreases in accounts payable and other accrued liabilities, and GENBAND's net loss, net of non-cash operating expenses. These usages of cash were partially offset by lower accounts receivable and decreases in prepaid expenses and other current assets, as well as changes in other noncurrent assets and liabilities. GENBAND's lower accounts receivable reflects its continued focus on improved timing of collections coupled with its historically higher revenue in the three months ended December 31. GENBAND's lower accounts receivable primarily reflects collections of its December 31, 2016 receivable balance. The decrease in accounts payable and accrued expenses was primarily related to GENBAND's employee compensation and related costs, including payments made in connection with GENBAND's bonus plans and sales commissions, and payments made in connection with its previously recorded restructuring initiatives. GENBAND's net loss, adjusted for non-cash items such as depreciation, amortization and foreign currency exchange loss, used about $5 million of cash.

Cash used in operating activities in the six months ended June 30, 2016 was primarily the result of decreases in accounts payable and other accrued liabilities, GENBAND's net loss, net of non-cash operating expenses, and increases in prepaid expenses and other current assets. These changes were partially offset by lower accounts receivable, the change in other noncurrent assets and liabilities, higher deferred revenue and lower inventory. GENBAND's lower accounts receivable primarily reflects its historically higher revenue in the three months ended December 31. The decrease in accounts payable and other accrued liabilities was primarily related to GENBAND's employee compensation and related costs, including payments made in connection with GENBAND's bonus plans and sales commissions, and payments made in connection with its previously recorded restructuring initiatives. GENBAND's net loss, adjusted for non-cash items such as depreciation, amortization and foreign currency exchange loss, used about $8 million of cash.

GENBAND's investing activities used approximately $4 million of cash in the six months ended June 30, 2017 for the purchase of property and equipment.

GENBAND's investing activities used approximately $8 million of cash in the six months ended June 30, 2016, comprised of $4 million of investments in property and equipment, $2 million of purchases of leasehold improvements reimbursed by lessors, and $2 million of purchases of perpetual licenses and capitalized patent costs.

GENBAND's financing activities provided over $1 million of cash in the six months ended June 30, 2017, almost entirely attributable to $19 million of borrowings and $17 million of principal payments on its revolving line of credit.

GENBAND's financing activities provided $15 million of cash in the six months ended June 30, 2016, primarily due to borrowings of $19 million, consisting of $10 million on its Subordinated Term Loan and $9 million on its then existing revolving line of credit with Comerica Bank. These borrowings were partially offset by principal payments totaling $4 million on its credit facility with Comerica Bank, consisting of over $2 million of payments on the three-year term loan and almost $2 million of payments on the revolving line of credit thereunder.

Based on GENBAND's financial condition at June 30, 2017 and current and anticipated future operations, GENBAND believes that its available cash, anticipated cash flow from operations and available borrowings under its revolving line of credit are sufficient to fund working capital and capital expenditure requirements for at least the next 12 months. It is difficult to predict future liquidity requirements with certainty. The rate at which GENBAND will consume cash will be dependent on the cash needs of future operations, including changes in working capital, which will, in turn, be directly affected by the levels of demand for its products, the timing and rate of expansion of its business, the resources GENBAND devotes to developing its products and any litigation settlements. GENBAND anticipates devoting substantial capital resources to continue its research and development efforts, to maintain sales, support and marketing, to improve its controls environment and for other general corporate activities.

SVB. The long-term related party debt is due on September 30, 2019 and is subordinate to the borrowings outstanding under the revolving line of credit.

The SVB Agreement requires GENBAND to comply with certain representations, warranties, periodic reporting and financial covenants, including maintaining a minimum free cash flow and minimum liquidity. As of December 31, 2016, GENBAND was in compliance with all covenants related to the SVB Agreement.

As of December 31, 2016, GENBAND's borrowings and letters of credit outstanding under the SVB Agreement were $17 million and $2 million, respectively. The availability remaining under the revolving credit line was nearly $31 million as of December 31, 2016.

GENBAND had net cash flows provided by operations of approximately $5 million in 2016 compared with cash used in operations in 2015 of $36 million. The increase in cash flows from operations in 2016 compared with 2015 of $41 million is primarily due to a lower net loss as a result of operational efficiencies and an overall increase in gross profit.

Cash provided by operating activities in 2016 was primarily the result of decreases in other operating assets and liabilities, and higher deferred revenue, partially offset by higher accounts receivable and inventory, lower accounts payable and other accrued expenses, and GENBAND's net loss. The increase in accounts receivable arose from higher revenue in 2016 compared to 2015, partially offset by the results of its continued focus on improved timing of collections. Deferred revenue balances will fluctuate as a result of timing of invoicing and revenue recognition. GENBAND's net loss, adjusted for non-cash items such as depreciation and amortization, share-based compensation, loss on foreign currency exchange, provision for doubtful accounts and provision for inventory obsolescence, provided about $2 million of cash.

Cash used in operating activities in 2015 was primarily the result of GENBAND's net loss, partially offset by lower accounts receivable and other operating assets and liabilities, higher deferred revenue and accrued expenses. The decrease in accounts receivable primarily reflects the impact of lower revenue in 2015 compared with 2014. The decrease in other operating assets was primarily the result of lower prepaid expenses. The increase in accrued expenses was primarily attributable to accrued professional and management fees, partially offset by lower amounts accrued for income taxes, accrued warranty, and royalties. GENBAND's net loss, adjusted for non-cash items, used about $59 million of cash.

GENBAND's investing activities used $13 million of cash in 2016 and $10 million of cash in 2015. In 2016, GENBAND used approximately $9 million of cash for the purchase of property and equipment, $2 million for purchases of leasehold improvements reimbursed by lessors and $2 million for purchases of perpetual licenses and capitalized patent costs. Investing activities in 2015 was comprised of $7 million of cash used to purchase property and equipment, $1 million of purchases of leasehold improvements reimbursed by lessors and $2 million of purchases of perpetual licenses and capitalized patent costs.

GENBAND's financing activities provided $6 million of cash in 2016 and nearly $41 million of cash in 2015. The 2016 amount was primarily comprised of $10 million of proceeds from the issuance of term debt due to a related party, and net borrowings of $0.5 million under its revolving line of credit, partially offset by $3 million of principal payments of debt and $1 million of payments for debt issue costs. The 2015 amount primarily arose from $30 million of proceeds from the issuance of term debt due to a related party and net borrowings of $17 million on its revolving line of credit, partially offset by $5 million of principal payments of debt.

Recent Accounting Pronouncements

In January 2017, the Financial Accounting Standards Board (which we refer to as the FASB) issued Accounting Standards Update (which we refer to as ASU) 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which removes the requirement to compare the implied fair value of goodwill with its carrying amount as part of step 2 of the goodwill impairment test. As a result, under ASU 2017-04, an entity should perform its goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. In addition, ASU 2017-04 clarifies the requirements for excluding and allocating foreign currency translation adjustments to reporting units in connection with an entity's testing of reporting units for

247

Table of Contents

goodwill impairment, clarifies that an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable, and makes minor changes to other related guidance within the Accounting Standards Codification (which we refer to as ASC). ASU 2017-04 is effective prospectively for GENBAND beginning January 1, 2021, with early adoption permitted for goodwill impairment tests performed on testing dates after January 1, 2017. GENBAND is currently evaluating the impact this ASU will have on its consolidated financial statements.

In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-entity Transfers of Assets Other Than Inventory. This ASU requires entities to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. This ASU, which requires modified retrospective application through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption, is effective for annual reporting periods beginning after December 15, 2018, with early adoption permitted. GENBAND is currently evaluating the impact this ASU will have on its consolidated financial statements.

In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. This ASU simplifies various aspects related to how share-based payment transactions are accounted for and presented in the financial statements, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This ASU requires prospective, retrospective, or modified retrospective application, depending on the amendment, and is effective for annual reporting periods beginning after December 15, 2017, with early adoption permitted. GENBAND is currently evaluating the impact this ASU will have on its consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). This new standard requires lessees, among other things, to recognize lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under previous authoritative guidance and introduces new disclosure requirements for leasing arrangements. ASU 2016-02 will be effective for GENBAND beginning in the year ended December 31, 2020, but early application is permitted. The standard must be adopted using a modified retrospective transition and provides for certain practical expedients. GENBAND is currently evaluating the impact this ASU will have on its consolidated financial statements.

In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern. This ASU requires management to evaluate whether there are conditions or events that exists that raise substantial doubt about an entity's ability to continue as a going concern within one year after the date the financial statements are issued and provide related disclosures. The standard was effective beginning with the year ended December 31, 2016.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which provides guidance for revenue recognition. This ASU will supersede the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance. It also supersedes some cost guidance included in Subtopic 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts. The standard can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption and is effective for annual reporting periods beginning after December 15, 2018. In 2016, there were four ASUs issued to clarify or provide technical corrections and improvements to ASU No. 2014-09. The clarifications include reporting revenue gross versus net, identifying performance obligations and licensing, narrow-scope improvements and practical expedients, and technical corrections and improvements. GENBAND is currently evaluating the impact all of these ASUs will have on its consolidated financial statements.

Quantitative and Qualitative Disclosures About Market Risk

GENBAND is exposed to a variety of market risks, including changes in interest rates affecting the SVB Agreement and foreign currency fluctuations.

GENBAND does not believe that a hypothetical 10% adverse movement in interest rates and foreign currency exchange rates for the six months ended June 30, 2017 would have had a material impact on its net loss.

Based on a sensitivity analysis at December 31, 2016, a 10% change in the foreign currency exchange rates for the year ended December 31, 2016 would have impacted GENBAND's net loss by approximately $2 million. This calculation assumes that all currencies change in the same direction and proportion relative to the U.S. dollar. GENBAND does not believe that a 10% adverse movement in interest rates would have had a material impact for the year ended December 31, 2016.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

Sonus, GENBAND, GB and GB II and other parties have entered into a merger agreement providing for the strategic business combination of Sonus, GENBAND, GB and GB II under a new holding company, New Solstice. As a result of the business combination, New Solstice will succeed to and continue to operate, directly or indirectly, the then existing businesses of Sonus, GENBAND, GB and GB II.

The unaudited pro forma condensed combined balance sheet as of June 30, 2017 and the unaudited pro forma condensed combined statement of operations for the year ended December 31, 2016 and for the six months ended June 30, 2017 have been prepared to reflect the mergers. The mergers will be accounted for as a business combination where Sonus is the acquirer and GENBAND is the acquiree. Accordingly, the unaudited pro forma condensed combined balance sheet combines the unaudited condensed consolidated balance sheets of Sonus and GENBAND as of June 30, 2017 and gives effect to the mergers as if they had been completed on June 30, 2017. The unaudited pro forma condensed combined statements of operations for the year ended December 31, 2016 and for the six months ended June 30, 2017 combine the historical condensed consolidated statements of operations of Sonus and GENBAND for the same periods, giving pro forma effect to the mergers as if they had been completed on January 1, 2016. The unaudited pro forma condensed combined financial statements exclude GB and GB II because they are holding companies with no operations. The historical financial information has been adjusted in the unaudited pro forma condensed combined financial statements to give effect to pro forma events that are (1) directly attributable to the mergers, (2) factually supportable, and (3) with respect to the statements of operations, expected to have a continuing impact on the combined results.

The unaudited pro forma condensed combined financial statements presented are based on the assumptions and adjustments described in the accompanying notes. The unaudited pro forma condensed combined financial statements are presented for illustrative purposes and do not purport to represent what the financial position or results of operations would actually have been if the mergers occurred as of the dates indicated or what such financial position or results would be for any future periods for the combined company. The unaudited pro forma condensed combined financial statements are based upon the respective historical consolidated financial statements of Sonus and GENBAND, and should be read in conjunction with the:

•
  accompanying notes to the unaudited pro forma condensed combined financial statements;
•
  separate historical audited consolidated financial statements of Sonus included in its Annual Report on Form 10-K for the year ended December 31, 2016 and the accompanying "Management's Discussion and Analysis of Financial Condition and Result of Operations", each as incorporated by reference into this joint proxy statement/prospectus;
•
  separate historical unaudited condensed consolidated financial statements of Sonus included in its Quarterly Reports on Form 10-Q for the three and six months ended June 30, 2017 and June 30, 2017 and the accompanying "Management's Discussion and Analysis of Financial Condition and Result of Operations", each as incorporated by reference into this joint proxy statement/prospectus;

The mergers are being accounted for as a business combination where Sonus is acquiring GENBAND. GENBAND's assets and liabilities will be measured and recognized at their fair values as of the date of the mergers, and consolidated with the assets, liabilities and results of operations of Sonus following the consummation of the mergers. The difference between the fair value of the purchase price consideration and the fair value of assets and liabilities acquired will be recorded as goodwill.

The unaudited pro forma condensed combined statements of operations do not include the benefits of any revenue, cost or other operating synergies that may result from the mergers or any related restructuring costs or certain amounts resulting from the mergers that were determined to be of a non-recurring nature.

Notes to Unaudited Pro Forma Condensed Combined Financial Statements

1. Description of Transaction and Basis of Presentation

Description of Transaction

On May 23, 2017, Sonus, a publicly traded entity, and GENBAND, GB and GB II, privately held entities, entered into a merger agreement which provides for the strategic business combination of Sonus, GENBAND, GB and GB II under a new holding company, New Solstice. The merger agreement, among other things, contemplates four separate mergers: the Sonus merger, the GENBAND merger, the GB merger and the GB II merger. The mergers will result in Sonus' business and the businesses of GENBAND, GB and GB II being held under New Solstice. Former Sonus stockholders will own approximately 50%, and former GENBAND party stockholders will own approximately 50%, of the shares of New Solstice common stock issued and outstanding immediately following the consummation of the mergers.

To prepare the unaudited pro forma condensed combined financial statements, Sonus adjusted GENBAND's assets and liabilities to their estimated fair values based on preliminary valuation work. As of the date of this joint proxy statement/prospectus, Sonus has not completed the detailed valuation work necessary to finalize the required estimated fair values of the GENBAND assets to be acquired and liabilities to be assumed and the related allocation of purchase price. The final allocation of the purchase price will be determined after the transaction is completed and after completion of an analysis to determine the estimated net fair value of GENBAND's assets and liabilities. Accordingly, the final acquisition accounting adjustments may be materially different from the unaudited pro forma adjustments. The unaudited pro forma condensed combined financial statements reflect material presentation adjustments made to GENBAND's consolidated statements of operations and consolidated balance sheet to conform to Sonus' presentation. Upon closing of the mergers, Sonus will review, in detail, GENBAND's accounting policies. As a result of that review, Sonus may identify additional presentation differences or differences between the accounting policies of the two companies, that when conformed, could have a material impact on the combined financial results. Based on information available at this time, Sonus is not aware of any differences that would have a material impact on the post-combination financial statements other than those presented in the pro forma condensed combined financial statements included herein. The unaudited pro forma condensed combined financial statements do not give effect to any cost savings, operating synergies or revenue synergies that may result from the mergers or the costs to achieve any such cost savings, operating synergies and revenue synergies. All material transactions between Sonus and GENBAND during the period presented in the unaudited pro forma condensed combined financial statements have been eliminated.

Basis of Presentation

The unaudited pro forma condensed combined financial statements were prepared in accordance with Article 11 of SEC Regulation S-X. The unaudited pro forma condensed combined balance sheet as of June 30, 2017 is presented as if the mergers had been completed on June 30, 2017. The unaudited pro forma condensed combined statements of operations for the year ended December 31, 2016 and for the six months ended June 30, 2017 assume that the mergers took place as of January 1, 2016, and combines the historical results of Sonus and GENBAND for the same period. Sonus is deemed to be the acquiring company and the mergers will be accounted for as a business combination in accordance with U.S. GAAP. Accordingly, the assets and liabilities of Sonus will be recorded as of the closing date at their respective carrying values and the acquired net assets of GENBAND will be recorded as of the closing date at their fair values, with the excess of the value of consideration transferred over the fair value of net assets acquired being recognized as goodwill. For the purpose of these unaudited pro forma financial statements, management of Sonus has determined a preliminary estimated purchase price for the business combination, and such amount has been calculated as

described in Note 2 to these unaudited pro forma condensed combined financial statements. The net assets acquired in connection with the transaction are at their estimated fair values. A final determination of these estimated fair values will be based on the actual net acquired assets of GENBAND as of the closing date.

2. Preliminary Consideration Transferred and Preliminary Fair Value of Net Assets Acquired

The unaudited pro forma condensed combined financial statements includes various assumptions, including those related to the preliminary purchase price allocation of the assets acquired and liabilities assumed of GENBAND based on management's preliminary estimates of fair value. The final purchase price allocation may differ significantly based on final appraisals, third-party valuations and analyses of the assets acquired and liabilities assumed. Accordingly, the preliminary allocation described below is subject to change.

The total estimated consideration transferred was determined as follows (in thousands):

Cash consideration: |  |  |  |
Repayment of GENBAND long-term debt and accrued interest, related party |  | $ | 46,443 |
Payment of GENBAND management fees due to OEP |  |  | 10,000 |
Payment of GENBAND estimated transaction fees |  |  | 9,000 |

The number of shares of New Solstice common stock that will be issued to the GENBAND shareholders will be the number of shares of common stock outstanding on the closing date. The estimated fair value of New Solstice common stock to be issued for GENBAND outstanding common stock is computed as follows (in thousands, except per share amount):

Total shares of New Solstice common stock to be issued to GENBAND shareholders |  |  | 50,681 |
Price per share of Sonus common stock on August 7, 2017 |  | $ | 6.91 |
​ | ​ | ​ | ​ | ​
Fair value of New Solstice common stock to be issued to GENBAND shareholders |  | $ | 350,206 |
​ | ​ | ​ | ​ | ​
​ | ​ | ​ | ​ | ​
​ | ​ | ​ | ​ | ​

A 10% increase in the stock price would result in total stock-based purchase consideration of $385.2 million, an increase of $35.0 million. A 10% decrease in the stock price would result in total stock-based purchase consideration of $315.2 million, a decrease of $35.0 million. Any such increase or decrease in the fair value of the stock-based purchase consideration would result in a corresponding increase or decrease to the goodwill recorded in connection with the transaction.

3. Pro Forma Adjustments

The unaudited pro forma condensed combined financial statements include pro forma adjustments giving effect to the mergers. The pro forma adjustments reflecting the completion of the mergers are based upon the accounting analysis conclusion that the mergers should be accounted for as a business combination and upon the assumptions set forth below.

The pro forma adjustments to the condensed combined financial statements are as follows:

(a)
  To record the estimated purchase consideration, including cash and marketable securities of $54.1 million and $30.3 million, respectively, comprised of $46.4 million to repay the outstanding principal and accrued interest of GENBAND's long-term debt, related party; $10.0 million to repay management fees due from GENBAND to OEP; $9.0 million for GENBAND's transaction fees in connection with the mergers and $19.0 million to repay the current amount outstanding under GENBAND's line of credit facility. Additional purchase consideration includes the issuance of 50.7 million shares of New Solstice common stock valued at an estimated $350.2 million as of August 7, 2017 and the issuance of a $22.5 million promissory note as estimated consideration paid to GENBAND shareholders in connection with the mergers.
(b)
  To record the preliminary purchase price allocation. See Note 2, "Preliminary Consideration Transferred and Preliminary Fair Value of Net Assets Acquired."
(c)
  To record a reduction of $7.1 million to marketable securities, representing Sonus' estimated remaining transaction costs in connection with the mergers that would be paid as of the closing date of the mergers, as it is assumed that the expense for these costs would be accrued in Sonus' historical financial results prior to that date and paid on the closing date. At June 30, 2017, $2.8 million of transaction costs had been paid and $1.9 million was accrued, with an additional estimated $5.3 million of costs to be expensed and paid, which amount is offset with an equal adjustment to accumulated deficit. These costs are considered to be non-recurring and, as such, are not included in the unaudited pro forma condensed combined statement of operations.
(d)
  To record $10.8 million of pre-combination stock-based compensation expense for unrecognized expense as of June 30, 2017 related to certain outstanding unvested stock options, restricted stock awards, restricted stock units and performance-based stock units which are being accelerated in connection with the mergers. These costs are considered to be non-recurring and, as such, are not included in the unaudited pro forma condensed combined statement of operations.
(e)
  To record an adjustment to Sonus' deferred tax asset valuation allowance. The mergers will result in the recognition of net deferred tax liabilities aggregating $18.0 million, which relate primarily to amortizable intangible assets recorded in the purchase price allocation. As these deferred tax liabilities will be used to offset future taxable income of the consolidated entity, the existing Sonus valuation allowance will be reduced to the extent of the deferred tax liabilities. This adjustment to the valuation allowance is considered to be non-recurring and, as such, is not included in the Unaudited Pro Forma Condensed Combined Statement of Operations.
(f)
  To reclassify GENBAND's historical accrued compensation and benefits and accrued restructuring to accrued expenses to conform to Sonus' balance sheet presentation.
(g)
  To eliminate revenue and cost of revenue amounts recognized by Sonus from sales to GENBAND of $3.3 million (comprised of $2.4 million of product revenue and cost of product revenue and $0.9 million of service revenue and cost of service revenue) for the year ended December 31, 2016 and $0.9 million (comprised of $0.5 million of product revenue and cost of product revenue and $0.4 million of service revenue and cost of service revenue) for the six months ended June 30, 2017. These amounts represent sales to GENBAND, which recognized the revenue and costs related to the products and services sold to a third party, and which are included in GENBAND's financial results for the respective periods.
(h)
  To reduce GENBAND's historical revenue as a result of preliminary fair value adjustments to deferred revenue (both current and noncurrent). The $42.5 million preliminary decrease in the fair value of the current portion of GENBAND's deferred revenue is comprised of a $20.1 million reduction to deferred product revenue and a $22.4 million reduction to deferred service revenue which is expected to be recognized as an adjustment to revenue within one year following the

mergers. The $5.1 million preliminary decrease in the fair value of the long-term portion of GENBAND's deferred service revenue is expected to be recognized as an adjustment to revenue over a three-year period beginning one year from the completion of the mergers, resulting in a $1.0 million pro forma reduction to service revenue in the six months ended June 30, 2017.

(i)
  To reverse previously recognized amortization of GENBAND's capitalized software development costs of $2.3 million and $1.7 million for the year ended December 31, 2016 and the six months ended June 30, 2017, respectively. The amortization expense reversed through this adjustment relates to capitalized software that was valued at $0 during the preliminary purchase price allocation.
(j)
  To eliminate historical amortization of acquired technology (reported as a separate line item within cost of revenue) and amortization of acquired intangible assets (reported as a separate line item within operating expenses) previously recognized by GENBAND. For the year ended December 31, 2016, GENBAND recognized expense of $2.8 million for the amortization of acquired technology and $4.6 million for the amortization of acquired intangible assets. For the six months ended June 30, 2017, GENBAND recognized expense of $1.0 million for the amortization of acquired technology and $1.8 million for the amortization of acquired intangible assets. The assets to which these expenses relate were re-valued as part of the assessment of assets acquired. The pro forma amortization expense adjustments include the amounts applicable to the re-valued acquired technology [see Note(k)].
(k)
  To record the amortization expense for the preliminary estimate of identifiable intangible assets arising from the mergers. The expense recorded in the respective pro forma statements of operations is as follows (in thousands):

|  | Useful life (years) |  | Statement of operations classification |  | Year ended December 31, 2016 |  | Six months ended June 30, 2017 |

*
  No pro forma amortization expense has been recorded in connection with the in-process research and development intangible assets because the related products are not yet generally available. Once the related products become generally available, these intangible assets will be amortized in relation to the expected cash flows from the individual intangible assets over their respective useful lives.

  To eliminate $9.8 million and $0.4 million of interest income reported by Sonus for the year ended December 31, 2016 and the six months ended June 30, 2017, respectively. Had the mergers been completed as of January 1, 2016, it is expected that Sonus' interest income would have been lower as a result of the net cash consideration paid of $63.0 million, assuming an average annual rate of return of 1.25%.
(m)
  To eliminate $5.2 million and $2.7 million of interest expense for the year ended December 31, 2016 and the six months ended June 30, 2017, respectively, associated with the repayment of the principal and accrued interest in connection with GENBAND's outstanding debt as a condition of consummating the mergers. Of the $5.2 million of interest expense reversed in the year ended December 31, 2016, $3.8 million related to the long-term debt, related party, $0.8 million related to the line of credit facility and $0.6 million related to a previous line of credit facility that was paid off during 2016. Of the $2.7 million of interest expense reversed in the six months ended June 30, 2017, $2.2 million related to the long-term debt, related party and $0.5 million related to the line of credit facility. At December 31, 2016, the principal balance of the long-term debt, related party was $40.0 million, with an interest rate of 10.5%, the outstanding principal balance on the line of credit facility was $17.0 million, with an interest rate of 4.4%. The previous line of credit facility had an interest rate of 5.25%, and there was no outstanding balance at December 31, 2016. At June 30, 2017, the principal balance of the long-term debt, related party was $40.0 million, with an interest rate of 10.0% and the outstanding principal balance on the line of credit facility was $19.0 million, with an interest rate of 4.47%.

  To record interest expense associated with the issuance of a $22.5 million promissory note as partial consideration for the acquisition of GENBAND. The promissory note bears interest at an annual rate of 7.5% for the first six months and 10% thereafter. Interest expense of $2.0 million and $1.1 million was recognized for the year ended December 31, 2016 and the six months ended June 30, 2017, respectively.

GENBAND EXECUTIVE AND DIRECTOR COMPENSATION

GENBAND Party Executive Compensation

This section discusses the material components of the executive compensation program offered to the executive officers of the GENBAND parties who would have been "named executive officers" for 2016 and who may continue to serve as executive officers of New Solstice following completion of the transactions. Such executive officers of the GENBAND parties consist of the following persons (who we refer to as the GENBAND Party Executive Officers):

•
  David Walsh, President and Chief Executive Officer of each GENBAND party
•
  Daryl E. Raiford, Executive Vice President and Chief Financial Officer of each GENBAND party
•
  Patrick Joggerst, Executive Vice President of Global Sales and Marketing of GENBAND

This discussion may contain forward-looking statements that are based on our current plans, considerations, expectations and determinations regarding future compensation programs. Actual compensation programs that GENBAND parties and their affiliates, including New Solstice, adopt following the closing of the mergers may differ materially from the currently planned programs summarized in this discussion. Further, notwithstanding the inclusion of disclosure regarding the GENBAND Party Executive Officers in this joint proxy statement/prospectus, New Solstice may determine in the future not to continue to employ the GENBAND Party Executive Officers as executive officers of New Solstice or otherwise.

All executive compensation described herein was paid by GENBAND. No GENBAND Party Executive Officer received any compensation from GB or GB II in connection with his or her services as an executive officer of the GENBAND parties. Each of the GENBAND parties is an "emerging growth company," within the meaning of the Jumpstart Our Business Startups Act, as amended (which we refer to as the Jobs Act), and has elected to comply with the reduced compensation disclosure requirements available to emerging growth companies under the JOBS Act.

2016 Summary Compensation Table

The following table presents summary information concerning all compensation earned by each GENBAND Party Executive Officer for services rendered to the GENBAND parties during the fiscal year ended December 31, 2016.

  The awards reported in this column reflects the GENBAND Class E Shares granted in 2016. The GENBAND Class E Shares are intended to be "profits interests." GENBAND believes that, despite the fact that the GENBAND Class E Shares do not require the payment of an exercise price, they are most similar economically to stock options, and as such, they are properly classified

as "options" under the definition provided in Item 402(a)(6)(i) of Regulation S-K under the Securities Act as an instrument with an "option-like feature."

(2)
  Amounts reflect the grant date fair value of the GENBAND Class E Shares computed in accordance with FASB ASC Topic 718, rather than the amounts paid to or realized by the applicable GENBAND Party Executive Officer. The assumptions used in the valuation of such GENBAND Class E Shares are as follows: (i) a dividend yield of 0%; (ii) volatility of 40%; (iii) a risk-free rate of 0.50%; and (iv) the period to liquidity event of 1.75 years. See Note 13 to the audited consolidated financial statements of GENBAND appearing elsewhere in this joint proxy statement/prospectus for additional information.

Narrative to the Summary Compensation Table

The primary elements of compensation for the GENBAND Party Executive Officers in 2016 were base salary, annual cash bonuses under the 2016 Short-Term Incentive Plan (which we refer to as the 2016 STIP), equity awards in the form of GENBAND Class E Shares and certain executive perquisites and benefits. The GENBAND Party Executive Officers also participate in employee benefit plans and programs that GENBAND offers to its other full-time employees.

Base Salary

The GENBAND Party Executive Officers receive a base salary to compensate them for the performance of services rendered to GENBAND each year. The base salary payable to each GENBAND Party Executive Officer is intended to provide a fixed component of compensation reflecting his or her skill set, experience, role and responsibilities. Base salaries for the GENBAND Party Executive Officers have generally been set at levels deemed necessary to attract and retain individuals with superior talent.

The base salaries for Mr. Walsh and Mr. Raiford were originally established in their employment agreements, but have been reviewed and adjusted thereafter. In 2016, Mr. Walsh and Mr. Joggerst received an annual base salary of $849,730 and $289,423, respectively. In 2016, Mr. Raiford's annual base salary was initially $425,000, but was increased to $500,000, effective December 12, 2016.

2016 Short-Term Incentive Plan

In 2016, each GENBAND Party Executive Officer participated in the 2016 STIP, an annual cash bonus plan based on GENBAND's performance. The bonuses for each GENBAND Party Executive Officer under the 2016 STIP were generally based equally on four company performance metrics: (1) customer bookings (generally calculated based on executed, binding customer contracts), (2) revenue, (3) EBITDA and (4) customer service. Payout in respect of each performance metric was based on attainment of threshold, mid or target performance, with payout at 25%, 65% and 100% of such metric's portion of target bonus opportunity, respectively. Based on achievement as compared to the applicable performance metrics, the compensation committee of GENBAND approved payout under the 2016 STIP at 48% of target. The compensation committee of GENBAND did not exercise any discretion to adjust the payouts to the GENBAND Party Executive Officers under the 2016 STIP and such payouts are set forth below:

Name |  | 2016 STIP Bonus Amount |  | Percentage of Target Bonus Opportunity for GENBAND Party Executive Officer |
--- | --- | --- | --- | --- | ---
David Walsh |  | $ | 192,000 |  |  | 48 | %
Daryl E. Raiford |  | $ | 180,000 |  |  | 48 | %
Patrick Joggerst |  | $ | 139,200 |  |  | 48 | %

Narrative to Director Compensation Table

Director Fees

Each independent director of GENBAND is entitled to compensation in connection with his or her services to GENBAND, and such compensation for 2016 included the following:

•
  $28,000 annual fee for all independent directors;
•
  An additional $26,502 fee for the lead independent director which represents a prorated portion of the $90,000 annual fee for such position (Steven Levy);
•
  An additional $8,750 annual fee for the chairmen of the compensation committee (Jon Bayless) and audit committee (Mark Lancaster); and
•
  An additional $4,376 annual fee for all other independent members of the compensation and audit committees (Steven Levy and Ray Rothrock).

The GENBAND director compensation for 2016 was reduced on a discretionary basis by the GENBAND board and annual fees (other than the annual fee for the lead independent director) are expected to be 12.5% higher in 2017. No directors of GB or GB II are entitled to any additional compensation from GB or GB II in connection with his or her services as a member of the board of such entities.

Consulting Fees for Non-Director Services

Alex Russo is party to a consulting agreement with GENBAND US LLC, a subsidiary of GENBAND, which provides for a monthly consulting fee of $33,333 or approximately $400,000 per annum. In addition, Mr. Russo is also eligible for a discretionary annual bonus with a target bonus opportunity equal to 50% of his annualized consulting fees. Mr. Russo's consulting term under his agreement will continue until terminated either by mutual agreement of the parties, by GENBAND US LLC upon fifteen days' written notice, or by either party in the event of a breach of the agreement. In the event of termination of the consulting term by GENBAND US LLC (other than due to breach of the agreement), Mr. Russo would continue to receive his consulting fees for six months following termination. The aggregate value of fifteen days' notice and the severance potentially payable to Mr. Russo under his consulting agreement is approximately $216,667.

Compensation Committee Interlocks and Insider Participation

During 2016, the members of the compensation committee of GENBAND were Mr. Bayless (chairman), Mr. Walsh, Mr. Rothrock, Mr. Smith and Mr. Koven. During 2016, the members of the compensation committee of GB were Mr. Bayless (chairman), Mr. Walsh, Mr. Rothrock, Mr. Smith and Mr. Koven. Mr. Walsh is party to an employment agreement and a retention bonus agreement with GENBAND, as well as an arrangement with the OEP Stockholders pursuant to which, following the consummation of the mergers, he will be eligible to receive a payment equal to two and one-half percent (2.5%) of any cash proceeds received by such stockholders for their shares of New Solstice common stock to the extent such cash proceeds exceed the greater of $600 million and the fair equity value of GENBAND, as of the consummation of the GENBAND merger. Apart from these transactions, no member of the GENBAND or GB Compensation Committees has any relationship that would be required to be reported under Item 404 of Regulation S-K under the Securities Act. No member of the GENBAND or GB Compensation Committees serves or served during the fiscal year as a member of the board of directors or compensation committee of a company that has one or more executive officers serving as a member of our board of directors or compensation committee. Thus, no interlocking relationship exists between any member of the GENBAND or GB boards or Compensation Committees and any member of the board or Compensation Committee of any other company, and none of these interlocking relationships have existed in the past.

DESCRIPTION OF NEW SOLSTICE CAPITAL STOCK

Upon completion of the mergers, stockholders of Sonus and the GENBAND parties who receive New Solstice common stock in the mergers will become stockholders of New Solstice. The following is a summary of the material terms of New Solstice capital stock as of the effective times of the mergers and is not complete. You should also refer to (i) the New Solstice charter, which will be in effect as of the effective time of the Sonus merger and the form of which is included as Annex F to this joint proxy statement/prospectus and is incorporated herein by reference, (ii) New Solstice's amended and restated by-laws (which we refer to as the New Solstice by-laws), which will be in effect as of the effective time of the Sonus merger and the form of which is included as Annex G to this joint proxy statement/prospectus and is incorporated herein by reference, and (iii) the applicable provisions of the DGCL. The following summary should be read in conjunction with the section entitled "Comparison of Stockholder Rights" beginning on page 294 of this joint proxy statement/prospectus.

Authorized Capital Stock

As of the effective time of the mergers, New Solstice will be authorized to issue up to 240,000,000 shares of common stock, $0.0001 par value per share, and 10,000,000 shares of preferred stock, $0.01 par value per share. Immediately following the mergers, New Solstice expects there to be approximately [ ] shares of New Solstice common stock issued and outstanding.

Common Stock

Dividend Rights

Holders of New Solstice common stock are entitled to receive ratably any dividends that may be declared by the board of directors out of legally available funds, subject to any preferential dividend rights of any outstanding preferred stock.

Voting Rights

Holders of New Solstice common stock are entitled to one vote for each share held on all matters submitted to a vote of the stockholders and do not have cumulative voting rights. Accordingly, holders of a majority of the shares voted can elect all of the directors then standing for election.

Liquidation Rights

Upon the liquidation, dissolution or winding up of New Solstice, the holders of New Solstice common stock are entitled to receive ratably assets available for distribution to New Solstice stockholders after the payment of all debts and other liabilities and subject to the prior rights of any outstanding preferred stock.

Other Rights

Other than as set forth in the stockholders agreement, holders of New Solstice common stock have no preemptive, subscription, redemption or conversion rights.

Preferred Stock

The New Solstice board of directors will be authorized without further stockholder approval to issue from time to time up to an aggregate of 10,000,000 shares of preferred stock in one or more series. The board of directors has discretion to fix the designations, preferences, relative, participating, optional or other special rights, and the qualifications, limitations or restrictions, if any, of the shares of each series, including the dividend rights, dividend rates, conversion rights, voting rights, term of redemption including sinking fund provisions, redemption price or prices, liquidation preferences and

289

Table of Contents

the number of shares constituting any series or designations of any series without further vote or action by the stockholders.

The purpose of authorizing the New Solstice board of directors to issue preferred stock and determine its rights and preferences is to eliminate delays associated with a stockholder vote on specific issuances. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions, future financings and other corporate purposes, could have the effect of making it more difficult for a third party to acquire, or could discourage a third party from seeking to acquire, a majority of New Solstice's outstanding voting stock. Immediately following the mergers, there will be no shares of preferred stock outstanding.

Delaware Law and Charter and By-Law Provisions; Anti-Takeover Effects

Certain provisions in the New Solstice charter and the New Solstice by-laws summarized below may be deemed to have an anti-takeover effect and may delay, deter or prevent a tender offer or takeover attempt that a stockholder might consider to be in its best interests, including attempts that might result in a premium being paid over the market price for the shares held by stockholders. These provisions are intended to enhance the likelihood of continuity and stability in the composition of the New Solstice board and in the policies formulated by the New Solstice board and to discourage certain types of transactions that may involve an actual or threatened change in control.

Removal of Directors; Vacancies

The New Solstice charter and the New Solstice by-laws to become effective on the closing of the mergers provide, subject to the stockholders agreement (for so long as the stockholders agreement is in effect):

•
  that directors may be removed from office at any time, (i) for cause by the affirmative vote of the holders of a majority of voting power of the shares of New Solstice stock entitled to vote for the election of directors, voting together as a single class, or (ii) without cause by (a) subject to clause (b), the affirmative vote of the holders of at least 662/3% of the voting power of the shares of New Solstice stock entitled to vote for the election of directors, voting together as a single class or (b) in the event recommended by at least two-thirds of the total number of authorized directors, including the approval of a majority of the independent directors (as such term is defined in the stockholders agreement), the affirmative vote of the holders of a majority of the voting power of the shares of New Solstice stock entitled to vote for the election of directors, voting as a single class; and
•
  that any vacancy on the New Solstice board of directors, however occurring, including a vacancy resulting from an enlargement of the board, may only be filled by the vote of a majority of the directors then in office.

The limitations on the removal of directors and filling of vacancies could have the effect of making it more difficult for a third party to acquire, or of discouraging a third party from acquiring, New Solstice.

Stockholder Action; Special Meetings of Stockholders; Advance Notice Requirements for Stockholder Proposals and Director Nominations; Supermajority Voting; Section 203 of the DGCL

The New Solstice charter and the New Solstice by-laws provide that, after the closing of the mergers:

•
  any action required or permitted to be taken by the New Solstice stockholders may be taken only at a duly called annual or special meeting of New Solstice stockholders and may not be taken by any consent in writing by such stockholders; and

290

Table of Contents

•
  special meetings of the stockholders may only be called by a majority of the total number of authorized directors, the president or by the board of directors, whether or not there exist any vacancies in previously authorized directorships, or (for so long as the stockholders agreement remains in effect) a majority of the independent directors (as such term is defined in the stockholders agreement).

The New Solstice by-laws will provide that, for nominations and other business to be "properly brought" at a meeting of stockholders, a stockholder of record at such time must have given timely notice to the Secretary of New Solstice and must comply with the other requirements set forth in the New Solstice by-laws. These provisions could delay until the next stockholders' meeting stockholder actions that are favored by the holders of a majority of the outstanding New Solstice voting securities. These provisions may also discourage another person or entity from making a tender offer for the New Solstice common stock, because the person or entity, even if it acquired a majority of New Solstice's outstanding voting securities, would be able to take action as a stockholder, such as electing new directors or approving a merger, only at a duly called stockholders meeting, and not by written consent.

The DGCL provides that an amendment to a corporation's certificate of incorporation requires that (i) the board of directors adopt a resolution setting forth the proposed amendment and declaring its advisability and either call a special meeting of the stockholders entitled to vote in respect thereof for consideration of such amendment or direct that the amendment be considered at the next annual meeting of the stockholders (provided a meeting or vote is required pursuant to Section 242 of the DGCL) and (ii) the stockholders approve the amendment by a majority of outstanding shares entitled to vote. The New Solstice charter will provide that the affirmative vote of the holders of at least 662/3% of the voting power of the outstanding New Solstice voting stock entitled to vote thereon (in addition to any separate class vote required by law or that may in the future be required pursuant to the terms of any outstanding preferred stock) is required to amend or repeal the provisions of Articles IV (to the extent it relates to the authority of the board of directors to issue shares of preferred stock in one or more series, the terms of which may be determined by the board of directors), V (Board of Directors), VII (Indemnification), IX (Business Combinations with Interested Stockholders), X (Certain Transactions), XI (Stockholder Action), XII (Exclusive Forum), XIII (Severability) or XIV (Amendments) of the New Solstice charter, or to reduce the numbers of authorized shares of common stock or preferred stock.

The New Solstice charter will provide that, subject to any limitations imposed by the New Solstice charter, the New Solstice by-laws may be altered, amended, or repealed, or new bylaws may be adopted, by resolution of the board duly adopted by a majority of the total number of directors which New Solstice would have if there were no vacancies or unfilled newly-created directorships, including (for so long as the stockholders agreement remains in effect) the approval of a majority of the independent directors (as such term is defined in the stockholders agreement). With respect to the power of holders of capital stock to adopt, amend and repeal the New Solstice by-laws, notwithstanding any other provision of the bylaws or any provision that might otherwise permit a lesser vote or no vote, in addition to any vote of the holders of any class or series of capital stock required by the bylaws or by law, the affirmative vote of the holders of the voting power of at least 662/3% of the shares of New Solstice's stock entitled to vote thereon, voting together as a single class, shall be required for any such alteration, amendment, repeal or adoption by the vote of the holders of any class or series of New Solstice's capital stock.

Section 203 of the DGCL generally prohibits "business combinations", including mergers, sales and leases of assets, issuances of securities and similar transactions by a corporation or a subsidiary with an interested stockholder who beneficially owns 15% or more of a corporation's voting stock, within three years after the person or entity becomes an interested stockholder, unless: (i) the board of directors of the target corporation has approved, before the acquisition time, either the business combination or the transaction that resulted in the person becoming an interested stockholder, (ii) upon consummation of

291

Table of Contents

the transaction that resulted in the person becoming an interested stockholder, the person owns at least 85% of the corporation's voting stock (excluding shares owned by directors who are officers and shares owned by employee stock plans in which participants do not have the right to determine confidentially whether shares will be tendered in a tender or exchange offer) or (iii) at or after the person or entity becomes an interested stockholder, the business combination is approved by the board of directors and authorized at a meeting of stockholders by the affirmative vote of at least 66-2/3% of the outstanding voting stock not owned by the interested stockholder.

Section 203 of the DGCL permits a Delaware corporation to elect not to be governed by the provisions of Section 203. Pursuant to the New Solstice charter, New Solstice will expressly elect not to be governed by the provisions of Section 203 of the DGCL. Instead, the New Solstice charter will provide that, notwithstanding any other provisions of the DGCL or the New Solstice charter, New Solstice shall not engage in any business combination with any interested stockholder for a period of three years following the time that such stockholder became an interested stockholder unless: (i) the New Solstice board has approved, before the acquisition time, either the business combination or the transaction that resulted in the person becoming an interested stockholder, (ii) upon consummation of the transaction that resulted in the person becoming an interested stockholder, the person owns at least 85% of the corporation's voting stock (excluding shares owned by directors who are officers and shares owned by employee stock plans in which participants do not have the right to determine confidentially whether shares will be tendered in a tender or exchange offer) or (iii) at or after the person or entity becomes an interested stockholder, the business combination is approved by two-thirds of the total number of authorized directors, whether or not there exist any vacancies in previously authorized directorships, and by a majority of the independent directors (as defined in the stockholders agreement).

The foregoing restriction will not apply if (i) a stockholder becomes an interested stockholder inadvertently and (a) as soon as practicable divests itself of ownership of sufficient shares so that the stockholder ceases to be an interested stockholder; and (b) would not, at any time within the three-year period immediately prior to a business combination between New Solstice and such stockholder, have been an interested stockholder but for the inadvertent acquisition of ownership; or (ii) the business combination is proposed prior to the consummation or abandonment of and subsequent to the earlier of the public announcement or the notice of a proposed transaction which (a) constitutes one of the transactions described in clause (A), (B) or (C) below; (b) is with or by a person who either was not an interested stockholder during the previous three years or who became an interested stockholder with the approval of the New Solstice board; and (c) is approved or not opposed by a majority of the New Solstice board then in office (but not less than one) who were directors prior to any person becoming an interested stockholder during the previous three years or were recommended for election or elected to succeed such directors by a majority of such directors.

The proposed transactions referred to in the preceding paragraph are limited to (A) a merger or consolidation of New Solstice (except for a merger in respect of which, pursuant to Section 251(f) of the DGCL, no vote of the stockholders is required); (B) a sale, lease, exchange, mortgage, pledge, transfer or other disposition (in one transaction or a series of transactions), whether as part of a dissolution or otherwise, of assets of New Solstice or of any of its direct or indirect majority-owned subsidiaries (other than to any direct or indirect wholly owned subsidiary or to New Solstice) having an aggregate market value equal to 50% or more of either that aggregate market value of all of the assets of New Solstice determined on a consolidated basis or the aggregate market value of all the outstanding stock of New Solstice; or (C) a proposed tender or exchange offer for 50% or more of the outstanding voting stock of New Solstice. New Solstice will give not less than 20 days' notice to all interested stockholders prior to the consummation of any of the transactions described in clause (A) or (B) above.

Authorized but Unissued Shares

The authorized but unissued shares of New Solstice common stock and New Solstice preferred stock are available for future issuance without stockholder approval, subject to any limitations imposed by NASDAQ listing standards. These additional shares may be used for a variety of corporate finance transactions, acquisitions, and employee benefit plans. The existence of authorized but unissued and unreserved capital stock and preferred stock could make more difficult or discourage an attempt to obtain control of New Solstice by means of a proxy contest, tender offer, merger or otherwise.

Choice of Forum

The New Solstice charter provides that unless New Solstice consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall, to the fullest extent permitted by law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of New Solstice, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer, other employee or stockholder of New Solstice to New Solstice or New Solstice's stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware, or (iv) any action asserting a claim arising pursuant to any provision of the New Solstice charter or the New Solstice by-laws or governed by the internal affairs doctrine.

Limitation of Liability and Indemnification

The New Solstice charter will provide that New Solstice directors and officers will be indemnified by New Solstice to the fullest extent permitted by Section 145 of the DGCL, against all expense, liability and loss (including attorneys' fees, judgements, fines, ERISA excise taxes or penalties and amounts paid in settlement) reasonably incurred or suffered by such person in connection with such action, suit or proceeding and any appeal therefrom, and such indemnification shall continue as to an indemnitee who has ceased to be a director, trustee, officer, employee or agent.

The New Solstice by-laws will provide that New Solstice shall indemnify, to the fullest extent permitted by applicable law, as the same exists or may be amended, any person who was or is made a party or is threatened to be made a party to or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of being or having been a director or officer of New Solstice; or while a director or officer of New Solstice, serving or having served at the request of New Solstice as a director, trustee, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan, against all expense, liability and loss (including attorneys' fees, judgments, fines, ERISA excise taxes or penalties and amounts paid in settlement) reasonably incurred or suffered by such indemnitee in connection therewith.

The New Solstice by-laws will further provide that the right to indemnification shall include the right to be paid by New Solstice the expenses (including attorneys' fees) incurred in defending any such proceeding in advance of its final disposition; provided, however, that, to the extent required by law, such advancement of expenses shall be made only upon New Solstice's receipt of an undertaking, by or on behalf of such indemnitee, to repay all amounts so advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal that such indemnitee is not entitled to be indemnified for such expenses under the bylaws or otherwise.

New Solstice may, to the extent authorized from time to time by the board, grant rights to indemnification, and to the advancement of expenses, to any employee or agent of New Solstice to the fullest extent provided by the bylaws with respect to the indemnification and advancement of expenses of directors and officers of the expenses payable in advance.

New Solstice may, but shall not be obligated to, purchase and maintain insurance at its expense on behalf of any such person.

COMPARISON OF STOCKHOLDER RIGHTS

Sonus, GB, GB II and New Solstice are each organized under the laws of the State of Delaware, and GENBAND is organized under the laws of the Cayman Islands. If the mergers are consummated, Sonus stockholders, GENBAND shareholders, GB stockholders and GB II stockholders will become stockholders of New Solstice. As New Solstice stockholders, after giving effect to the mergers, your rights with respect thereto will be governed by Delaware law, including the DGCL, as well as New Solstice's constituent documents. This section summarizes material differences between the rights of Sonus stockholders, GENBAND shareholders, GB stockholders and GB II stockholders before consummation of the mergers, and New Solstice stockholders after consummation of the mergers. These differences in stockholder rights result from the differences between the respective constituent documents of Sonus, the GENBAND parties and New Solstice and the difference between Delaware law and the laws of the Cayman Islands.

The following summary is not a complete statement of the rights of the stockholders of any of the five companies or a complete description of the specific provisions referred to below. The identification of specific differences is not intended to indicate that other equally significant or more significant differences do not exist. This summary is qualified in its entirety by reference to Sonus', each GENBAND party's and New Solstice's constituent documents, which you are urged to read carefully.

The form of the New Solstice charter and the New Solstice by-laws are attached as Annexes F and G, respectively, to this joint proxy statement/prospectus and are incorporated herein by reference. Sonus has filed with the SEC its constituent documents and will send copies of these documents to you, without charge, upon your request. The GENBAND parties will send copies of their respective constituent documents to GENBAND shareholders, GB stockholders and GB II stockholders, without charge, upon such shareholders' request.

Initially, five of such directors will be designated by the OEP Stockholders holding a majority of the shares held by the OEP Stockholders (which we sometimes refer to as the OEP Majority) at any given time, two of which must be independent for purposes of applicable NASDAQ and SEC rules and must satisfy the other independence criteria specified in the stockholders agreement (who we refer to in this section as the independent directors).

Business Combination or Anti-Takeover Statutes
Section 203 of the DGCL generally prohibits "business combinations," including mergers, sales and leases of assets, issuances of securities and similar transactions by a corporation or a subsidiary with an interested stockholder who beneficially owns 15% or more of a corporation's voting stock, within three years after the person or entity becomes an interested stockholder, unless: (i) the board of directors of the target corporation has approved, before the acquisition time, either the business combination or the transaction that resulted in the person becoming an interested stockholder, (ii) upon consummation of the transaction that resulted in the person becoming an interested stockholder, the person owns at least 85% of the corporation's voting stock (excluding shares owned by directors who are officers and shares owned by employee stock plans in which participants do not have the right to determine confidentially whether shares will be tendered in a tender or exchange offer) or (iii) at or after the person or entity becomes an interested stockholder, the business combination is approved by the board of directors and authorized at a meeting of stockholders by the affirmative vote of at least 662/3% of the outstanding voting stock not owned by the interested stockholder. Sonus has not opted out of the protections of Section 203 of the DGCL. As a result, the statute applies to Sonus. |  | Section 203 of the DGCL permits a Delaware corporation to elect not to be governed by the provisions of Section 203. Pursuant to the New Solstice charter, New Solstice will expressly elect not to be governed by the provisions of Section 203 of the DGCL. Instead, the New Solstice charter will provide that, notwithstanding any other provisions of the DGCL or the New Solstice charter, New Solstice shall not engage in any business combination with any interested stockholder for a period of three years following the time that such stockholder became an interested stockholder unless: (i) the New Solstice board has approved, before the acquisition time, either the business combination or the transaction that resulted in the person becoming an interested stockholder, (ii) upon consummation of the transaction that resulted in the person becoming an interested stockholder, the person owns at least 85% of the corporation's voting stock (excluding shares owned by directors who are officers and shares owned by employee stock plans in which participants do not have the right to determine confidentially whether shares will be tendered in a tender or exchange offer) or (iii) at or after the person or entity becomes an interested stockholder, the business combination is approved by two-thirds of the total number of authorized directors, whether or not there exist any vacancies in previously authorized directorships, and by a majority of the independent directors (as defined in the stockholders agreement).

Appraisal Rights
Under the DGCL, a stockholder may dissent from, and receive payments in cash for, the fair value of his or her shares as appraised by the Court of Chancery of the State of Delaware in the event of certain mergers and consolidations.

Further, no appraisal rights are available to stockholders of the surviving corporation if the merger did not require the vote of the stockholders of the surviving corporation. Notwithstanding the foregoing, appraisal rights are available if stockholders are required by the terms of the merger agreement to accept for their shares anything other than (i) shares of stock of the surviving corporation, (ii) shares of stock of another corporation that will either be listed on a national securities exchange or held of record by more than 2,000 holders, (iii) cash instead of fractional shares or (iv) any combination of clauses (i)-(iii).

Number and Qualification of Directors |  |  |  |  |  |
The GENBAND board currently consists of 10 members. GENBAND's Articles provide that the board shall consist of 9 members, provided that the members may by Ordinary Resolution increase or reduce the number of directors so long as the board consists of at least one person. In accordance with the terms of the GENBAND Stockholders Agreement, the GENBAND board shall consist of nine directors, with such members consisting of (a) the person serving as the chief executive officer of GENBAND, (b) three persons designated by OEP, (c) two persons designated by the Blocker VC Investors (as defined therein) holding at least a majority of the aggregate issued and outstanding shares of GENBAND shares held by all Blocker VC Investors (as defined therein), and (d) three persons designated by OEP that are not affiliated with GENBAND, GB or any Investor (as defined therein). The number of persons serving on the GENBAND board may be increased at any time (by vote or written consent) by the holders of a majority of the outstanding GENBAND Class A Shares. Upon any such increase of the size of the GENBAND board, the holders then-holding a majority of the outstanding GENBAND Class A Shares shall designate the persons to fill such additional seats. |  | The GB board currently consists of 10 members. The GB bylaws provide that the number of directors which shall constitute a whole board shall be fixed in accordance with the GENBAND Stockholders Agreement. In accordance with the terms of the GENBAND Stockholders Agreement, the GB board shall initially consist of nine members, with such members consisting of (a) the person then serving as the chief executive officer of GB (or, if there is no chief executive officer, the person then serving as the president), (b) three persons designated by OEP, (c) two persons designated by the Blocker VC Investors (as defined therein) holding at least a majority of the aggregate issued and outstanding shares of GENBAND shares held by all Blocker VC Investors (as defined therein), and (d) three persons designated by OEP that are not affiliated with GENBAND, GB or any Investor (as defined therein). The number of persons serving on the GB board shall equal the number of persons on the GENBAND board. Upon any increase in the size of the GB board above nine or if one of the parties set forth above does not designate a person to serve on the GB board, then any vacancies shall be designed by OEP for so long as OEP holds a majority of the GENBAND Class A shares held by the VC Investors. |  | The GB II board currently consists of 10 members. The GB II bylaws provide that the number of directors which shall constitute the whole board shall not be less than one and that the stockholders at each annual meeting of GB II shall determine the number of directors, and the number of directors may be increased or decreased at any time or from time to time by the stockholders or the directors by a vote of the majority of the directors then in office, except that any such decrease by vote of the directors shall only be made to eliminate vacancies existing by reason of death, resignation or removal of one or more directors. In accordance with the terms of the GENBAND Stockholders Agreement, the GB II board initially consisted of two members. Upon any increase of the size of the GB II board above two, any vacancies were and are designated by GENBAND and must be reasonably acceptable to GB II stockholders. Prior to the appointment of any successor to the GB II directors or any new directors resulting from the expansion of the GB II board, GENBAND must provide the GB II stockholders with written notice of such proposed successors or new directors five business days prior to the effective date of such appointment. If, during such five business day period, GENBAND receives objections from GB II stockholders holding a majority of the |  | In accordance with the terms of the stockholders agreement, for so long as the OEP Stockholders beneficially own at least 10% of the shares initially issued in connection with the consummation of the mergers (which we sometimes refer to as the Initial OEP Shares), the New Solstice board will be comprised of nine directors. Initially, five of such directors will be designated by the OEP Stockholders holding a majority of the shares held by the OEP Stockholders (which we sometimes refer to as the OEP Majority) at any given time, two of which must be independent for purposes of applicable NASDAQ and SEC rules and must satisfy the other independence criteria specified in the stockholders agreement (who we refer to in this section as the independent directors). If OEP Stockholders reduce their ownership of the Initial OEP Shares, the number of directors they have the right to designate will be reduced (with the right to designate any directors being eliminated if the OEP Stockholders cease to own at least 10% of the Initial OEP Shares). The nominating and corporate governance committee will designate as directors (i) the Chief Executive Officer of New Solstice (which we sometimes refer to as the CEO Director) and (ii) the remaining directors comprising the New Solstice board (that is, of the eight directors other than the CEO Director, those not

The CEO Director may be removed if such director ceases to serve as the Chief Executive Officer of New Solstice, and the remaining directors may be removed if such removal is directed or approved by the nominating and corporate governance committee.

Limitation on Director Liability |  |  |  |  |  |
Cayman Islands law does not limit the extent to which a company's memorandum and articles of association may provide for indemnification of officers and directors, except to the extent any such provision may be held by the Cayman Islands courts to be contrary to public policy, such as to provide indemnification against willful default, fraud or the consequences of committing a crime. GENBAND's Articles provide that each director and officer of GENBAND shall be indemnified out of the assets of GENBAND, same in respect of any liability they may incur by reason of their own actual fraud or willful default. |  | The DGCL provides that a corporation may include in its certificate of incorporation a provision eliminating the liability of a director to the corporation or its stockholders for monetary damages for a breach of the director's fiduciary duties, except liability for any breach of the director's duty of loyalty to the corporation's stockholders, for acts or omissions not in good faith or that involve intentional misconduct or knowing violation of law, under Section 174 of the DGCL (which deals generally with unlawful payments of dividends, stock repurchases and redemptions) and for any transaction from which the director derived an improper personal benefit. The GB charter provides that the director of GB is not personally liable to GB or its stockholders for monetary damages for breach of fiduciary duty as a director to the fullest extent permitted by law. If the DGCL is amended, after approval by the stockholders of Article IX (regarding director liability) of the GB bylaws, to authorize corporation action further eliminating or limited the personal liability of directors, then the liability of a director of GB shall be eliminated or limited to the fullest extent permitted by the DGCL, as so amended. |  | The DGCL provides that a corporation may include in its certificate of incorporation a provision eliminating the liability of a director to the corporation or its stockholders for monetary damages for a breach of the director's fiduciary duties, except liability for any breach of the director's duty of loyalty to the corporation's stockholders, for acts or omissions not in good faith or that involve intentional misconduct or knowing violation of law, under Section 174 of the DGCL (which deals generally with unlawful payments of dividends, stock repurchases and redemptions) and for any transaction from which the director derived an improper personal benefit. The GB II charter provides that GB II eliminates the personal liability of each member of its board and its stockholders for monetary damages for breach of fiduciary duty as a director, provided, however, that, to the extent provided by applicable law, the foregoing does not eliminate or limit the liability of a director (i) for any breach of such director's duty of loyalty to GB II or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL or (iv) for any transaction from which such director derived an improper personal benefit. |  | The DGCL provides that a corporation may include in its certificate of incorporation a provision eliminating the liability of a director to the corporation or its stockholders for monetary damages for a breach of the director's fiduciary duties, except liability for any breach of the director's duty of loyalty to the corporation's stockholders, for acts or omissions not in good faith or that involve intentional misconduct or knowing violation of law, under Section 174 of the DGCL (which deals generally with unlawful payments of dividends, stock repurchases and redemptions) and for any transaction from which the director derived an improper personal benefit. The New Solstice charter will provide that a director of New Solstice is not personally liable to New Solstice or its stockholders for monetary damages for breach of a fiduciary duty as a director, except, to the extent required from time to time by applicable law, for liability (i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL or (iv) for any transaction from which the director derived any improper personal benefit.

The GB bylaws provide that GB directors, officers, employees or agents of GB, will be indemnified by GB to the fullest extent permitted by Section 145 of the DGCL, against all expenses (including attorneys' fees), judgements, fines and amounts paid in settlement and/or other matters referred to or covered by Section 145. The GB bylaws further provide that the right to indemnification shall include the right to be paid by GB the expenses (including attorneys' fees) incurred by a present or former director or officer of GB in defending a civil, criminal, administrative or investigative action, suit or proceeding in advance of the final disposition of such action, suit or proceeding upon receipt |  | The GB II charter provides that, to the fullest extent permitted by applicable law, GB II is authorized to provide indemnification of (and advancement of expenses to) directors, officers and agents of GB II (and any other persons to which the DGCL permits GB II to provide indemnification) through bylaw provisions, agreements with such agents or other persons, vote of stockholders or disinterested directors or otherwise, in excess of the indemnification and advancement otherwise permitted by Section 145 of DGCL. The GB II charter provides further that any indemnities provided and granted under the GB II charter shall not be exclusive of any other rights or protections afforded an individual under any contract or vote of shareholders or disinterested directors or otherwise. The GB II bylaws provide that GB II shall indemnify its officers and directors to the full extent the corporation is permitted or required to do so by the DGCL. In furtherance of and not in limitation of the foregoing, GB II shall advance expenses, including attorneys' fees, incurred by an officer or director of GB II in defending any civil, criminal, administrative or investigative action, suit or proceeding in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such |  | The New Solstice charter will provide that New Solstice directors and officers will be indemnified by New Solstice to the fullest extent permitted by Section 145 of the DGCL, against all expense, liability and loss (including attorneys' fees, judgements, fines, ERISA excise taxes or penalties and amounts paid in settlement) reasonably incurred or suffered by such person in connection with such action, suit or proceeding and any appeal therefrom, and such indemnification shall continue as to an indemnitee who has ceased to be a director, trustee, officer, employee or agent. The New Solstice by-laws will provide that New Solstice shall indemnify, to the fullest extent permitted by applicable law, as the same exists or may be amended, any person who was or is made a party or is threatened to be made a party to or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of being or having been a director or officer of New Solstice; or while a director or officer of New Solstice, serving or having served at the request of New Solstice as a director, trustee, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan, against all expense, liability and loss

The New Solstice by-laws will further provide that the right to indemnification shall include the right to be paid by New Solstice the expenses (including attorneys' fees) incurred in defending any such proceeding in advance of its final disposition; provided, however, that, to the extent required by law, such advancement of expenses shall be made only upon New Solstice's receipt of an undertaking, by or on behalf of such indemnitee, to repay all amounts so advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal that such indemnitee is not entitled to be indemnified for such expenses under the bylaws or otherwise. New Solstice may, to the extent authorized from time to time by the board, grant rights to indemnification, and to the advancement of expenses, to any employee or agent of New Solstice to the fullest extent provided by the bylaws with respect to the indemnification and advancement of expenses of directors and officers of the expenses payable in advance. New Solstice may, but shall not be obligated to, purchase and maintain insurance at its expense on behalf of any such person.

Further, no appraisal rights are available to stockholders of the surviving corporation if the merger did not require the vote of the stockholders of the surviving corporation. Notwithstanding the foregoing, appraisal rights are available if stockholders are required by the terms of the merger agreement to accept for their shares anything other than (i) shares of stock of the surviving corporation, (ii) shares of stock of another corporation that will either be listed on a national securities exchange or held of record by more than 2,000 holders, (iii) cash instead of fractional shares or (iv) any combination of clauses (i)-(iii).

Notwithstanding the foregoing, appraisal rights are available if stockholders are required by the terms of the merger agreement to accept for their shares anything other than (i) shares of stock of the surviving corporation, (ii) shares of stock of another corporation that will either be listed on a national securities exchange or held of record by more than 2,000 holders, (iii) cash instead of fractional shares or (iv) any combination of clauses (i)-(iii). Appraisal rights are also available under the DGCL in certain other circumstances, including

RELATED PERSON TRANSACTIONS

Sonus

Certain related person transactions involving the directors and executive officers of Sonus are described in more detail in the section entitled "The Mergers—Interests of Directors and Executive Officers in the Transactions—Interests of Directors and Executive Officers of Sonus in the Transactions" beginning on page 171 of this joint proxy statement/prospectus.

The GENBAND Parties

Certain related person transactions involving the directors and executive officers of the GENBAND parties are described in more detail in the section entitled "The Mergers—Interests of Directors and Executive Officers in the Transactions—Interests of Directors and Executive Officers of the GENBAND Parties in the Transactions" beginning on page 177 of this joint proxy statement/prospectus.

GENBAND is party to a management fee agreement (which we refer to as the management fee agreement), dated as of May 28, 2015, with OEP which will be terminated in connection with the closing. Pursuant to the terms of the management fee agreement, GENBAND agrees to pay OEP an annual management fee equal to $1,750,000 in consideration for the management and advisory services provided by OEP to GENBAND from time to time. The management fee is payable on the first business day following the anniversary of the management fee agreement. All management fees payable to OEP (approximately $10 million) are expected to be paid off prior to the consummation of the mergers.

GENBAND is party to the Subordinated Term Loan with OEP Parent, which bears interest at 10%, compounding quarterly, with a maturity date of September 30, 2019. As of August 7, 2017, there were borrowings outstanding of $40 million, with no additional available borrowing capacity. Borrowings under the Subordinated Term Loan are unsecured and are subordinate to GENBAND's revolving credit facility. No prepayment of the Subordinated Term Loan is allowed pursuant to the SVB Agreement until the SVB Agreement expires. Upon the occurrence of an Event of Default (as defined under the Subordinated Term Loan), the interest rate would increase to 12%. All outstanding amounts under the Subordinated Term Loan are expected to be repaid in full in connection with the consummation of the mergers.

GENBAND US LLC and GENBAND Ireland Limited, each a subsidiary of GENBAND, are parties to a master development services agreement, dated as of April 2011, with Nortel Networks Netaş Telekomünikasyon A.Ş. (which we refer to as Netas), a company organized and existing under the laws of the Republic of Turkey. Netas, a significant vendor of GENBAND, was formerly majority-owned by OEP. GENBAND made payments of approximately $22.3 million to Netas in 2016 and approximately $5.6 million to Netas in the first quarter of 2017. In addition, GENBAND received approximately $555,000 from Netas in 2016 and approximately $321,000 in the first quarter of 2017 from Netas. In December 2016, OEP entered into an agreement to sell its ownership interest in Netas to ZTE, a multinational ICT solutions vendor. The sale to ZTE closed in August 2017.

The merger agreement contemplates, as a condition to the closing of the transactions contemplated thereby, that at the closing, New Solstice will enter into a stockholders agreement with the OEP Stockholders. See the section entitled "Other Related Agreements—Principal Stockholders Agreement" beginning on page 214 of this joint proxy statement/prospectus for a further discussion of the stockholders agreement.

GENBAND, GB and GB II are party to the GENBAND Stockholders Agreement, pursuant to which OEP has the right to, among other things, cause shareholders of each GENBAND party holding a majority of shares of such GENBAND party to vote in favor of the approval of the GENBAND mergers.

APPRAISAL RIGHTS

Sonus Stockholder Appraisal Rights

Under the DGCL, Sonus stockholders do not have appraisal rights in connection with the Sonus merger.

GENBAND Shareholder Dissenter Rights

With respect to the GENBAND merger, the Companies Law (2016 Revision) provides for a right of dissenting stockholders, in certain situations, to be paid the fair value of their shares upon their dissenting to the merger if they follow a prescribed procedure. That procedure is as follows:

•
  the shareholder must give their written objection to the merger to the exempted company before the vote on the merger, including a statement that the shareholder proposes to demand payment for their shares if the merger is authorized by the vote;
•
  within 20 days following the date on which the merger is approved by the stockholders, the exempted company must give written notice to each shareholder who made a written objection;
•
  a shareholder must within 20 days following receipt of such notice from the exempted company, give the exempted company a written notice of their intention to dissent including, among other details, a demand for payment of the fair value of their shares;
•
  within seven days following the date of the expiration of the period set out in the immediately preceding paragraph or seven days following the date on which the plan of merger is filed, whichever is later, the constituent company or the surviving company must make a written offer to each dissenting shareholder to purchase their shares at a price that the company determines is their fair value and if the exempted company and the shareholder agree the price within 30 days following the date on which the offer was made, the exempted company must pay the shareholder such amount; and
•
  if the exempted company and the stockholder fail to agree on a price within such 30 day period, within 20 days following the date on which such 30 day period expires, the exempted company must (and any dissenting stockholders may) file a petition with the Cayman Islands Grand Court for a determination of the fair value and such petition must be accompanied by a list of the names and addresses of the dissenting stockholders with whom agreements as to the fair value of their shares have not been reached by the exempted company.

At the hearing of that petition, the court has the power to determine the fair value of the shares together with a fair rate of interest, if any, to be paid by the exempted company upon the amount determined to be the fair value. Any dissenting shareholder whose name appears on the list filed by the exempted company may participate fully in all proceedings until the determination of fair value is reached. These rights of a dissenting shareholder are not available in certain circumstances, for example, (i) to dissenters holding shares of any class in respect of which an open market exists on a recognized stock exchange or recognized interdealer quotation system at the relevant date; or (ii) where the consideration for such shares to be contributed are shares of the surviving company (or depository receipts in respect thereof) or shares of any other company (or depository receipts in respect thereof) which are listed on a national securities exchange or designated as a national market system security on a recognized interdealer quotation system or held of record by more than two thousand holders.

Notwithstanding the above, in accordance with the GENBAND Stockholders Agreement, OEP has the right to require shareholders holding a majority of GENBAND shares to vote in favor of the GENBAND merger. To the extent a GENBAND shareholder does not vote in favor of (or return a separate proxy voting in favor of) the adoption of the merger agreement and the approval of the

340

Table of Contents

GENBAND merger, OEP may exercise the proxy granted to it by the GENBAND Stockholders Agreement to vote any such shareholder's shares in favor of the adoption of the merger agreement and the approval of the GENBAND merger. Accordingly, GENBAND shareholders would waive their dissenters' rights in connection with the GENBAND merger.

Dissenter rights with respect to holders of GENBAND shareholders in connection with the GENBAND merger are therefore subject to OEP's rights under the GENBAND Stockholders Agreement with respect to the GENBAND shareholders as discussed above.

GB and GB II Stockholder Appraisal Rights

As a statutory matter appraisal rights are available with respect to the GB merger and the GB II merger under Section 262 of the DGCL (which we refer to as Section 262). A copy of Section 262 of the DGCL is attached to this joint proxy statement/prospectus as Annex L, and the description of Section 262 set forth herein is qualified in its entirety thereby.

Although, as a statutory matter appraisal rights are available with respect to the GB merger and the GB II merger under Section 262, under the terms of the GENBAND Stockholders Agreement, OEP has the right to require stockholders holding a majority of common stock of GB and GB II stockholders to vote in favor of the GB merger or the GB II merger, as applicable. To the extent a GB stockholder or GB II stockholder does not vote in favor of (or return a separate proxy voting in favor of) the adoption of the merger agreement and the approval of the GB merger or GB II merger, as applicable, OEP may exercise the proxy granted to it by the GENBAND Stockholders Agreement to vote any such stockholder's shares in favor of the adoption of the merger agreement and the approval of the GB merger or GB II merger, as applicable. Under Section 262 of the DGCL, only stockholders who do not vote in favor of a merger are entitled to exercise appraisal rights in connection therewith. Accordingly, any stockholder whose shares are voted in favor of the GB merger or the GB II merger, including pursuant to the provisions of the GENBAND Stockholders Agreement, will not be entitled to exercise appraisal rights in connection with such mergers.

Although, for the reasons described above, stockholders of GB and GB II party to the GENBAND Stockholders Agreement may ultimately not be entitled exercise any appraisal rights in connection with the GB merger or the GB II merger, this section is intended as a brief summary of certain provisions of Section 262 that a stockholder who is entitled to exercise appraisal rights must follow to demand and perfect such appraisal rights. The following summary does not constitute any legal or other advice, nor does it constitute a recommendation that stockholders exercise their appraisal rights under Section 262. GB and GB II stockholders should carefully review the full text of Section 262 as well as the information discussed below. Strict compliance with the statutory procedures in Section 262 is required. Failure to follow precisely any of the statutory requirements will result in the loss of your appraisal rights.

A record holder of shares of GB common stock or GB II common stock, as applicable, who properly makes the demand described below with respect to such shares, who continuously is the record holder of such shares through the effective time of the GB merger or GB II merger (as applicable), who otherwise complies with the statutory requirements of Section 262, who neither votes in favor of the GB merger or GB II merger (as applicable) nor consents thereto in writing and who does not withdraw their demand for appraisal of such shares or otherwise lose their appraisal rights will be entitled to an appraisal of his, her or its shares by the Delaware Court of Chancery (which we refer to as the Delaware Court) of the fair value of his, her or its shares of GB common stock or GB II common stock (as applicable) exclusive of any element of value arising from the accomplishment or expectation of the GB merger or GB II merger (as applicable), together with a fair rate of interest, as determined by the Delaware Court. In determining the fair value of shares, the Delaware Court will take into account all relevant factors. The "fair value" could be greater than, less than or the same as

341

Table of Contents

the consideration that the stockholder would have received in connection with the GB merger or GB II merger, as applicable. All references in this summary of appraisal rights to a "stockholder" or "holders of shares of GB common stock or GB II common stock" are to the record holder or holders of shares of GB common stock or GB II common stock (as applicable).

Under Section 262, where a merger is to be submitted for approval at a meeting of stockholders, such as the GB special meeting or GB II special meeting, not less than 20 days prior to the meeting a constituent corporation must notify each of the holders of its stock for whom appraisal rights are available that such appraisal rights are available and include in each such notice a copy of Section 262. This joint proxy statement/prospectus shall constitute such notice of appraisal rights to the record holders of GB common stock and GB II common stock.

Holders of shares of GB common stock or of GB II common stock who desire to exercise their appraisal rights must not vote in favor of the GB merger or the GB II merger, respectively, and must deliver to GB or GB II, as applicable, a separate written demand for appraisal of his, her or its shares prior to the taking of the vote of the stockholders of GB or of GB II on the GB merger or the GB II merger at the GB special meeting or the GB II special meeting, as applicable. A demand for appraisal must be executed by or on behalf of the stockholder of record and must reasonably inform the applicable corporation of the identity of the stockholder of record and that such stockholder intends thereby to demand appraisal of such stockholder's shares of stock of such corporation. A proxy or vote against a merger will not by itself constitute such a demand. Within ten days after the effective time of the GB merger and the GB II merger, as applicable, GB Merger Sub must provide notice of the effective time of the GB merger and the GB II merger, as applicable, to all stockholders of GB and GB II who have complied with Section 262 and who have not voted in favor of or consented to the applicable merger.

A stockholder of GB or of GB II who elects to exercise appraisal rights should mail or deliver his, her or its written demand to GB or GB II, respectively, by mail at 3605 E. Plano Parkway, Plano, Texas 75074, Attention: Corporate Secretary.

A person having a beneficial interest in shares of GB common stock or in shares of GB II common stock that are held of record in the name of another person, such as a broker, fiduciary, depositary or other nominee, must act promptly to cause the record holder to follow the steps summarized herein properly and in a timely manner to perfect appraisal rights. If the shares of GB common stock or the shares of GB II common stock are owned of record by a person other than the beneficial owner, including a broker, fiduciary (such as a trustee, guardian or custodian), depositary or other nominee, such demand must be executed by or for the record owner. If the shares of GB common stock or of GB II common stock are owned of record by more than one person, as in a joint tenancy or tenancy in common, such demand must be executed by or for all joint owners. An authorized agent, including an agent for two or more joint owners, may execute the demand for appraisal for a stockholder of record; however, the agent must identify the record owner and expressly disclose the fact that, in exercising the demand, such person is acting as agent for the record owner.

Within 120 days after the effective time of the GB merger or GB II merger, as applicable, either GB Merger Sub or any stockholder of GB or of GB II, as applicable, who has complied with the provisions of Section 262 may commence an appraisal proceeding by filing a petition in the Delaware Court, with a copy served on GB Merger Sub in the case of a petition filed by a stockholder, demanding a determination of the fair value of the shares of all dissenting stockholders of GB or of GB II, as the case may be. There is no present intent on the part of GB Merger Sub to file an appraisal petition and stockholders seeking to exercise appraisal rights should not assume that GB Merger Sub will file such a petition or that GB Merger Sub will initiate any negotiations with respect to the fair value of such shares. Accordingly, holders of stock of GB or of GB II who desire to have their shares appraised should file any petitions necessary for the perfection of their appraisal rights

342

Table of Contents

within the time periods and in the manner prescribed in Section 262. Within 120 days after the effective time of the mergers, any stockholder of GB or of GB II who has theretofore complied with the applicable provisions of Section 262 will be entitled, upon written request, to receive from GB Merger Sub a statement setting forth the aggregate number of shares of, as applicable, GB common stock or GB II common stock not voting in favor of the applicable merger and with respect to which demands for appraisal were received by GB or GB II and the number of holders of such shares. Such statement must be mailed by GB Merger Sub within 10 days after the written request therefor has been received by GB Merger Sub or within 10 days after expiration of the period for delivery of demands for appraisal pursuant to Section 262, whichever is later. A person who is the beneficial owner of shares stock held in a voting trust or by a nominee on behalf of such person may, in such person's own name, file a petition or request from the corporation the statement described in the previous sentence.

If a petition for appraisal is timely filed by a stockholder and a copy of the petition is served upon GB Merger Sub, then GB Merger Sub will be obligated, within 20 days, to file with the Delaware Register in Chancery a duly verified list containing the names and addresses of all stockholders who have demanded an appraisal of their shares of GB or GB II common stock, as applicable, with whom agreements as to the value of their shares of stock have not been reached. After notice to stockholders who have demanded appraisal, if such notice is ordered by the Delaware Court, the Delaware Court is empowered to conduct a hearing upon the petition and to determine those stockholders who have complied with Section 262 and who have become entitled to the appraisal rights provided by Section 262. The Delaware Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Delaware Court may dismiss the proceedings as to such stockholder. Where proceedings as to all stockholders who have demanded appraisal are not dismissed, the appraisal proceeding shall be conducted, as to the shares of GB common stock or of GB II common stock, as the case may be, owned by such stockholders, in accordance with the rules of the Delaware Court, including any rules specifically governing appraisal proceedings. Through such proceeding the Delaware Court shall determine the fair value of such shares exclusive of any element of value arising from the accomplishment or expectation of the GB merger or GB II merger (as applicable), together with interest, if any, to be paid upon the amount determined to be the fair value. Unless the Delaware Court, in its discretion, determines otherwise for good cause shown, interest on an appraisal award will accrue and compound quarterly from the effective time of the applicable merger through the date the judgment is paid at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between such effective time and the date of payment of the judgment. At any time before the entry of judgment in any appraisal proceeding, GB Merger Sub may pay to each stockholder of GB or of GB II entitled to appraisal an amount in cash, in which case interest shall accrue thereafter as provided in the preceding sentence only upon the sum of (1) the difference, if any, between the amount so paid and the fair value of shares of GB or of GB II (as applicable) as determined by the Delaware Court and (2) interest theretofore accrued, unless paid at that time.

Although GB and GB II each believes that the applicable merger consideration is fair, no representation is made as to the outcome of the appraisal of fair value as determined by the Delaware Court and stockholders should recognize that such an appraisal could result in a determination of a value higher or lower than, or the same as, the applicable merger consideration. Moreover, GB Merger Sub does not anticipate offering more than the merger consideration to any stockholder exercising appraisal rights and reserves the right to assert, in any appraisal proceeding, that, for purposes of Section 262, the "fair value" of a share of GB common stock or of a share of GB II common stock is less than the applicable merger consideration. In determining "fair value", the Delaware Court is required to take into account all relevant factors. In Weinberger v. UOP, Inc. the Delaware Supreme Court discussed the factors that could be considered in determining fair value in an appraisal

343

Table of Contents

proceeding, stating that "proof of value by any techniques or methods which are generally considered acceptable in the financial community and otherwise admissible in court" should be considered and that "[f]air price obviously requires consideration of all relevant factors involving the value of a company." The Delaware Supreme Court has stated that in making this determination of fair value the court must consider market value, asset value, dividends, earnings prospects, the nature of the enterprise and any other facts which could be ascertained as of the date of the merger which throw any light on future prospects of the merged corporation. Section 262 provides that fair value is to be "exclusive of any element of value arising from the accomplishment or expectation of the merger." In Cede & Co. v. Technicolor, Inc., the Delaware Supreme Court stated that such exclusion is a "narrow exclusion [that] does not encompass known elements of value," but which rather applies only to the speculative elements of value arising from such accomplishment or expectation. In Weinberger, the Delaware Supreme Court construed Section 262 to mean that "elements of future value, including the nature of the enterprise, which are known or susceptible of proof as of the date of the merger and not the product of speculation, may be considered."

The cost of the appraisal proceeding may be determined by the Delaware Court and taxed against the parties as the Delaware Court deems equitable in the circumstances. However, costs do not include attorneys' and expert witness fees. Each dissenting stockholder is responsible for his, her or its attorneys' and expert witness expenses, although, upon application of a dissenting stockholder, the Delaware Court may order that all or a portion of the expenses incurred by any dissenting stockholder in connection with the appraisal proceeding, including without limitation, reasonable attorneys' fees and the fees and expenses of experts, be charged pro rata against the value of all shares of stock entitled to appraisal.

Any holder of shares of GB common stock or GB II common stock who has duly demanded appraisal in compliance with Section 262 will not, after the effective time of the applicable merger, be entitled to vote for any purpose any shares subject to such demand or to receive payment of dividends or other distributions on such shares, except for dividends or distributions payable to stockholders of record at a date prior to such effective time.

At any time within 60 days after the effective time of the applicable merger, any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party will have the right to withdraw such demand for appraisal and to accept the terms offered in the GB merger or GB II merger (as applicable); after this period, the stockholder may withdraw such demand for appraisal only with the consent of GB Merger Sub. With respect to each of GB and GB II, if no petition for appraisal with respect to shares of such corporation is filed with the Delaware Court within 120 days after the effective time of the applicable merger, the rights to appraisal of the stockholders of such corporation shall cease, and all holders of shares of stock of such corporation will be entitled to receive the consideration offered pursuant to the merger agreement. Inasmuch as GB Merger Sub has no obligation to file such a petition, and GB Merger Sub has no present intention to do so, any holder of shares of GB common stock or of GB II common stock who desires such a petition to be filed is advised to file it on a timely basis. Any stockholder of either GB or GB II may withdraw such stockholder's demand for appraisal by delivering to GB Merger Sub a written withdrawal of his, her or its demand for appraisal and acceptance of the applicable merger consideration, except (i) that any such attempt to withdraw made more than 60 days after the effective time of the applicable merger will require written approval of GB Merger Sub and (ii) that no appraisal proceeding in the Delaware Court shall be dismissed as to any stockholder without the approval of the Delaware Court, and such approval may be conditioned upon such terms as the Delaware Court deems just, provided, however, that this provision shall not affect the right of any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party to withdraw such stockholder's demand for appraisal and to accept the terms offered upon the GB merger or GB II merger (as applicable) within 60 days after the effective time of such merger.

Notwithstanding the foregoing description of Section 262, in accordance with the GENBAND Stockholders Agreement, stockholders of GB and GB II party to the GENBAND Stockholders Agreement may be required to vote in favor of the GB merger or the GB II merger, as applicable, which would have the effect of waiving appraisal rights of such stockholders that would otherwise be available. In addition, under the GENBAND Stockholders Agreement, each stockholder of GB and GB II party thereto has agreed to waive appraisal rights in connection with certain mergers and OEP may, in its sole discretion, request such a waiver from any or all stockholders of GB and GB II, at such time as OEP deems advisable (whether before or after the effectiveness of the GB merger or the GB II merger).

FUTURE STOCKHOLDER PROPOSALS

To be considered for inclusion in the proxy statement relating to Sonus' annual meeting of stockholders to be held in 2018, stockholder proposals must be received at Sonus' principal executive offices no later than December 29, 2017, which is not less than 120 calendar days before the date of Sonus' proxy statement was released to its stockholders in connection with the prior year's annual meeting of stockholders, and must otherwise comply with the rules promulgated by the SEC. If the date of Sonus' annual meeting next year is changed by more than 30 days from the anniversary date of this year's annual meeting held on June 9, 2017, then the deadline is a reasonable time before Sonus begins to print and mail proxy materials.

According to Sonus' bylaws, Sonus must receive other proposals of stockholders (including director nominations) intended to be presented at its 2018 annual meeting of stockholders but not included in the proxy statement by the close of business on March 11, 2018, but not before February 9, 2018, which is not later than the ninetieth (90th) day nor earlier than the one hundred twentieth (120th) day prior to the first anniversary of the date of it 2017 annual meeting of stockholders. Such proposals must be delivered to the Secretary of Sonus at Sonus' principal executive offices. However, in the event Sonus' 2018 annual meeting of stockholders is scheduled to be held on a date before May 10, 2018, or after August 18, 2018, which are dates 30 days before or 70 days after the first anniversary of Sonus' 2017 annual meeting of stockholders, then the notice must be received by Sonus at its principal executive offices not earlier than the close of business on the 120th day prior to such annual meeting and not later than the close of business on the later of the 90th day before the scheduled date of such annual meeting or the 10th day after the day on which Sonus first makes a public announcement of the date of such annual meeting. Any proposals that are not made in accordance with the above standards may not be presented at Sonus' 2018 annual meeting of stockholders.

If the mergers are consummated, Sonus will not have public stockholders and there will be no public participation in any future meeting of stockholders of Sonus. However, if the mergers are not consummated, Sonus expects to hold its 2018 annual meeting of stockholders at or around the time at which Sonus' 2018 annual meeting would normally take place, although Sonus reserves the right to delay its annual meeting as may be permitted under applicable law.

Report of Independent Auditors

To the Board of Directors of GENBAND Holdings Company and subsidiaries

We have audited the accompanying consolidated financial statements of GENBAND Holdings Company and its subsidiaries, which comprise the consolidated balance sheets as of December 31, 2016 and 2015 and the related consolidated statements of operations, comprehensive loss, changes in convertible preferred stock and stockholders' deficit and cash flows for each of the three years in the period ended December 31, 2016.

Management's Responsibility for the Consolidated Financial Statements

Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with accounting principles generally accepted in the United States of America; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

Auditor's Responsibility

Our responsibility is to express an opinion on the consolidated financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on our judgment, including the assessment of the risks of material misstatement of the consolidated financial statements, whether due to fraud or error. In making those risk assessments, we consider internal control relevant to the Company's preparation and fair presentation of the consolidated financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of GENBAND Holdings Company and its subsidiaries at December 31, 2016 and 2015, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2016 in accordance with accounting principles generally accepted in the United States of America.

Dallas, Texas
March 17, 2017, except for the change in the manner in which the Company accounts for convertible preferred stock as discussed in Note 12 to the consolidated financial statements, as to which the date is June 27, 2017.

performance. GENBAND Care services include managing software updates, hardware maintenance, hardware repair services and managed spares programs and emergency assistance during disaster recovery.

Note 2. Summary of Significant Accounting Policies

Basis of Presentation

The consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America ("US GAAP") for all periods presented.

Principles of Consolidation

The consolidated financial statements of the Company include all majority owned subsidiaries and assets and liabilities of GB Holdings. All intercompany transactions between and among the Company and its subsidiaries have been eliminated.

Use of Estimates

The preparation of consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the amounts reported. Estimates and judgments relied upon in preparing these consolidated financial statements include revenue recognition for multiple element arrangements, accrued warranty, income taxes, depreciation, amortization, employee benefits, share-based compensation, contingencies, inventory, intangible assets and liability valuations. The Company regularly assesses these estimates and records changes in estimates in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that the Company believes to be reasonable under the circumstances. Actual results may or may not differ from those estimates.

Reclassifications

Certain reclassifications, not affecting previously reported net loss, have been made to the previously issued financial statements to conform to the current period presentation.

Cash and Cash Equivalents

Cash and cash equivalents include cash deposited with financial institutions and liquid investments with original maturity dates equal to or less than three months. The Company holds cash and cash equivalents at major financial institutions, which often exceed Federal Deposit Insurance Corporation insured limits. Historically, the Company has not experienced any losses due to such bank depository concentration.

Foreign Currency Translation

The Company's consolidated financial statements are presented in US dollars ("USD"). The Company has reviewed the functional currency for all international operations in order to evaluate the appropriate functional currency for each location. This determination was made by assessing each of

Note 2. Summary of Significant Accounting Policies (Continued)

the foreign entities and the nature of their operations. After evaluating the relevant economic factors, the Company concluded that the operations in each of the foreign locations are relatively self-contained and integrated within their own particular country or economic environment, thus leading to the conclusion that the local currency should also be the functional currency. All foreign currency statements are translated from their functional currency into USD at the exchange rates in effect at the balance sheet dates for all assets and liabilities and at average rates for all revenue and expenses. The unrealized gains and losses on the net investment in these foreign operations are accumulated as a component of accumulated other comprehensive loss.

Foreign currency translation adjustments of $1,033, $7,234 and $7,568 were recorded in other comprehensive loss for the years ended December 31, 2016, 2015 and 2014, respectively. The loss (gain) on foreign currency exchange transactions of $1,295, $(4,871) and $(1,980) was recorded in other expense (income), net for the years ended December 31, 2016, 2015 and 2014, respectively.

Revenue Recognition

The Company derives revenue from the sales of telecommunications hardware and software products, complex customized solutions, and services, including post-contractual support, maintenance, installation and training that are generally sold pursuant to a contract. The terms of the contracts, taken as a whole, determine the appropriate revenue recognition models to be applied. Product revenue includes revenue from arrangements with software related services such as engineering, where the services cannot be separated from the arrangement because the services are essential or fair value cannot be established under the software revenue recognition guidance. In addition, product revenue includes all amounts billed to customers related to shipping and handling with the related expense as a component of cost of revenue in the accompanying consolidated statements of operations. Where services are sold stand-alone or can be separated from product sales in a bundled arrangement, service revenue is reported separately in the consolidated statements of operations.

We primarily derive subscription revenue from fees received from customers for time-based license arrangements and CPaaS offerings. We generally invoice subscription agreements in advance over the subscription period. Subscription revenue is generally recognized ratably over the subscription term when all revenue recognition criteria have been met and is included in product revenue in the consolidated statements of operations.

The Company makes significant judgments and estimates to determine revenue to be recognized in any accounting period. Material differences may result in the amount and timing of revenue for any period if the Company makes different judgments or utilizes different estimates. These estimates affect unbilled accounts receivable and deferred revenue in the consolidated balance sheets and total revenue in the consolidated statements of operations. In making these judgments, the Company uses the following assumptions and estimates:

Persuasive evidence of an arrangement. The Company considers a non-cancellable executed agreement (such as a customer purchase order, contract, etc.), or a group of closely-related agreements signed by all parties involved to be persuasive evidence of an arrangement.

Note 2. Summary of Significant Accounting Policies (Continued)

Delivery has occurred. The Company generally considers delivery to have occurred when title to and the risk of loss of the products has passed to the customer and no post-delivery obligations exist, except for support. In instances where there are post-delivery obligations, delivery is deemed to occur when the customer specifications have been met with customer acceptance or delivery of the additional elements has occurred. For arrangements where the criteria for revenue recognition have not been met because legal title or risk of loss on products does not transfer to the customer until final payment has been received or where delivery has not occurred, revenue is deferred to a later period when the outstanding criteria have been met.

Fees are fixed or determinable. The Company assesses whether fees are fixed or determinable at the time of sale. The Company considers the fee to be fixed or determinable if the fees are due within the Company's standard payment terms and the fees are not subject to refund or adjustment. If the arrangement fees are not fixed or determinable, including arrangements with extended payment terms, revenue is recognized as cash is collected.

Collection is probable. The Company evaluates credit worthiness for all customers with significant transactions at the time of the transaction. Collection is deemed probable if the Company expects that the customer will be able to pay amounts under the arrangement as payments become due. If the Company determines that collection is not probable, revenue is deferred and recognized upon cash collection.

Depending on the terms of the contract and types of products and services sold, the Company recognizes revenue following the guidance for multiple-element arrangements and software revenue recognition in addition to the general revenue recognition guidance. Revenues are reduced for returns, allowances, discounts and other offerings in accordance with the agreement terms.

For multiple-element arrangements, the Company separates deliverables into more than one unit of accounting if the delivered item(s) have value to the customer on a stand-alone basis, and delivery of the undelivered item(s) is probable and substantially in the Company's control.

The Company determines the selling price for each deliverable based upon the selling price hierarchy for multiple-deliverable arrangements. Under this hierarchy, the selling price for each deliverable is determined using vendor specific objective evidence ("VSOE") of selling price, if it exists; otherwise selling price is determined based on third-party evidence ("TPE") of selling price. If neither VSOE nor TPE of selling price exist, the Company uses its best estimate of selling price ("BESP") for that deliverable.

VSOE is established by the price charged when the item is sold separately on a stand-alone basis or based on the contractual renewal provision. The Company has VSOE for some, but not all, offerings. In cases where VSOE does not exist, the Company has been unable to establish TPE of selling price because there are relatively few observable competitor transactions along with varying levels of customization of products that make it difficult to compare to competitors' products and services. In determining BESP, the Company considers market conditions as well as entity-specific factors which include the impact to pricing based on geography, the pricing and profit objectives by customer class and region, consideration of any customization needed, the expected technological life,

instances or probability of selling the product/service on a stand-alone basis and the use of third parties, among other factors.

For arrangements without significant customization and where hardware and software components together provide the product's essential functionality, the Company recognizes revenue allocated to delivered items that are not contingent on the future delivery of products, services, or other performance obligations, including where customer-specified return or refund privileges exist. Once the Company allocates revenue to each deliverable, the Company recognizes revenue in accordance with its revenue recognition policy noted herein.

For sales of software and software related services, the Company generally uses the residual method to allocate the arrangement consideration. Under the residual method, the amount of consideration allocated to the delivered items equals the total value of software deliverables less the fair value of the undelivered items. For software arrangements where fair value does not exist for any undelivered item, revenue is not recognized until the earlier of (i) delivery of such item or (ii) when fair value of the undelivered item is established, unless the undelivered item is a service, in which case revenue is recognized as the service is performed under the cumulative catch-up method once the service is the remaining undelivered item.

Service elements are generally recognized according to the proportional performance method. The proportional performance method is used when the provision of services extends beyond an accounting period with more than one performance act, and permits the recognition of revenue ratably over the service period when no other pattern of performance is discernible. The nature of the service contract is reviewed to determine which revenue recognition method best reflects the nature of services performed. Provided all other revenue recognition criteria have been met, the revenue recognition method selected reflects the pattern in which the obligations to the customers have been fulfilled.

Deferred revenue

Deferred revenue in the consolidated balance sheets generally consists of post-contract customer support ("PCS") services that are deferred and recognized over the support term and revenue transactions that have outstanding deliverables. Deferred revenue which is not expected to be recognized over the next 12 months is classified as deferred revenue, net of current portion, in the consolidated balance sheets.

Deferred Costs

The Company defers costs for all customer sales arrangements in which there is a deferral of revenue recognition. Deferred costs consist of direct and associated costs related to the arrangement, such as the cost of the hardware, installation costs, third-party costs and other direct costs associated with the revenue. These costs are deferred up to the fair value of the products or services being sold and are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.

Goodwill and Intangible Assets

Business combinations have been accounted for using the acquisition method. Accordingly, the Company records the assets acquired and liabilities assumed in business combinations at their respective fair values at the date of acquisition, with any excess purchase price recorded as goodwill. This method also requires, among other things, expensing acquisition and integration costs, capitalization of in-process research and development separate from goodwill at the acquisition date fair value, and accounting for acquisition-related restructuring cost accruals subsequent to the acquisition date. The valuation of intangible assets requires significant estimates and assumptions including, but not limited to, determining the timing and expected costs to complete development projects, estimating future cash flows from product sales, developing appropriate discount rates, estimating probability rates for the successful completion of development projects, continuation of customer relationships and renewal of customer contracts and approximating the useful lives of the intangible assets acquired. Intangible assets, other than goodwill are generally amortized based on the expected pattern of benefit to future periods using estimates of undiscounted cash flows, or on a straight-line basis.

Goodwill has an indefinite useful life and is not amortized, but is evaluated for impairment at the reporting unit level annually, on October 1, or whenever events or changes in circumstances indicate that the carrying value may not be fully recoverable. In evaluating whether goodwill is impaired, the Company may first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. If it is determined that the two-step quantitative test is necessary, the fair value of the reporting unit to which the goodwill is assigned is compared to the reporting unit's carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill is not considered impaired. If the carrying amount of the reporting unit exceeds its fair value, the second step of the goodwill impairment test is performed to measure the amount of impairment loss, if any. The second step of the goodwill impairment test compares the implied fair value of the reporting unit's goodwill with the carrying amount of that goodwill. The implied fair value of goodwill is determined by performing an assumed purchase price allocation, using the reporting unit fair value (as determined in Step 1) as the purchase price. If the carrying amount of goodwill exceeds the implied fair value, an impairment loss is recognized in an amount equal to that excess. Determining the fair value of reporting units requires management to make a number of judgments about assumptions and estimates that are highly subjective and that are based on unobservable inputs. The actual results may differ from these assumptions and estimates, and it is possible that such differences could have a material impact on the Company's consolidated financial statements.

Long-lived assets, including intangible assets other than goodwill, are evaluated for impairment whenever events or changes in circumstances indicate that the net book value of an asset may not be fully recoverable. When such qualitative factors and circumstances exist, the Company compares the projected undiscounted future cash flows associated with related groups of assets over their estimated useful lives against their respective carrying amounts. Impairment, if any, is based on the excess of the carrying amount over the fair value of those assets and is recorded in the period in which the determination was made. The Company's estimate of future cash flows requires significant judgments and assumptions which may vary from actual cash flows.

Contingent Consideration

Contingent consideration, which includes earnout payments in connection with certain acquisitions, is recognized at fair value on the acquisition date and remeasured each reporting period with subsequent adjustments recognized in the Company's consolidated statements of operations. Changes in the fair value of contingent consideration liabilities may result from changes in discount rates, changes in the timing and amount of sales and/or other specific milestone estimates and changes in probability assumptions with respect to the likelihood of achieving the various earnout criteria. These changes could cause a material impact to, and volatility in the Company's operating results. Earnout payments are reflected in cash flows from financing activities and the changes in fair value are reflected in cash flows from operating activities in the consolidated statements of cash flows.

Research and Development Costs

Research and development costs associated with new product software development, improvement of existing products, process improvement and product use technologies are charged to expense in the period in which they are incurred. These costs consist primarily of employee salaries and benefits, occupancy costs, consulting costs and the cost of development equipment and supplies.

Advertising Costs

Advertising costs are expensed as incurred and are recorded within sales and marketing in the accompanying consolidated statements of operations. Advertising costs, primarily consisting of public relations, trade shows and other advertising costs totaled $2,250, $2,461 and $3,739 for the years ended December 31, 2016, 2015 and 2014, respectively.

Warranty Costs

The Company's products are covered by a standard product warranty that extends for periods typically ranging from one to three years from the date of sale. The Company's accrued warranty reflects estimated material and labor costs for potential or actual product issues in its installed base that are not covered under maintenance contracts but for which the Company expects to incur an obligation. The Company's accrued warranty, classified as accrued expenses on the consolidated balance sheets, was $1,567 and $1,564 as of December 31, 2016 and 2015, respectively.

Accounts Receivable

Accounts receivable are carried at original invoice amount less an allowance for doubtful accounts that represents an estimate of losses that could result from collection issues. Revenue that has been earned but remains unbilled is recorded as a component of accounts receivable, net. The Company specifically analyzes accounts receivable, customer credit-worthiness, current economic trends and changes in customer payment terms and collection trends when evaluating the adequacy of its allowance for doubtful accounts. The Company writes off accounts receivable balances against the allowance for doubtful accounts, net of any amounts recorded in deferred revenue, when it ceases collection activities. The Company generally does not charge interest on accounts receivable. Any change in the assumptions used in analyzing a specific account receivable may result in the recognition

Note 2. Summary of Significant Accounting Policies (Continued)

of an additional provision for doubtful accounts during the period in which the change occurs. The Company does not have any off-balance sheet credit exposures related to its customers.

Inventory

Inventory is valued at lower of cost or market. Cost is determined using standard cost, which approximates actual cost on a first-in, first-out basis. On an ongoing basis, inventory is reviewed and written down for estimated obsolescence or unmarketable inventory equal to the difference between the costs of inventory and the estimated net realizable value based upon forecasts for future customer demand and market conditions. Any adjustment to inventory as a result of an estimated obsolescence or net realizable condition is reflected as a component of cost of revenue. At the point of the loss recognition, a new, lower-cost basis for the respective inventory is established, and any subsequent improvements in facts and circumstances do not result in the restoration or increase to create a newly established cost basis.

Property and Equipment

Property and equipment is stated at cost less accumulated depreciation. Depreciation expense is computed using the straight-line basis over the shorter of the estimated useful life or remaining lease term.

Expenditures for repairs and maintenance are charged to expense when incurred while expenditures for major improvements are capitalized and depreciated. Expenditures for major improvements such as leasehold improvements or qualifying internal use software costs, incurred during the application development stage consisting primarily of outside services and purchased software license costs, are capitalized and amortized. Upon retirement or disposition of property and equipment, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is recognized.

The Company also capitalizes certain development costs incurred in connection with its CPaaS. These capitalized costs are primarily related to the Company's development of its CPaaS communications platform that is hosted by the Company and accessed by its customers on a subscription basis. Costs incurred in the preliminary stages of development are expensed as incurred. Once an application has reached the development stage, direct internal and external costs are capitalized until the software is substantially complete and ready for its intended use. Capitalized software development costs are amortized into cost of revenue on a straight-line basis over the estimated useful life of the related technology, generally two years.

Income Taxes

The Company accounts for income taxes under the asset and liability method prescribed by accounting guidance. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. The Company periodically assesses the recoverability of its deferred tax assets based upon expected future earnings, future deductibility of the asset, and changes in applicable tax laws and other factors. If the Company determines that it is more likely than not that

the deferred tax asset will not be fully recoverable against future taxable income, a valuation allowance may be established for the difference between the asset balance and the amount expected to be recoverable in the future. The allowance will result in a charge to the Company's consolidated statements of operations. Further, the Company records its income taxes receivable and payable based upon its estimated income tax liability.

The Company accounts for uncertain tax positions, if any, utilizing the two-step approach. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, based on the technical merits of the position. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. A liability is recorded (or a tax related asset is reduced) for the unrecognized tax benefits when a tax position does not meet these criteria. The Company recognizes interest income, interest expense and penalties related to unrecognized tax benefits in income tax provision (benefit) in the consolidated statements of operations.

Defined Benefit Plans

The Company recognizes retirement benefit assets or liabilities in the consolidated balance sheets reflecting the funded status of pension and other retirement benefit plans. Retirement benefit assets and liabilities are adjusted for the difference between the benefit obligations and the plan assets at fair value (measured at year end), with the offset recorded directly in stockholders' deficit through accumulated other comprehensive loss, net of tax. The amount recorded in stockholders' deficit represents the after-tax unamortized actuarial gains or losses, unamortized transition obligations and unamortized prior service costs.

Share-Based Compensation

The Company measures and recognizes compensation expense for share-based awards based on estimated fair values on the date of grant using the Black-Scholes option-pricing model. This model is affected by the Company's calculated stock price as well as estimates regarding a number of variables, including expected stock price volatility over the expected term of the award. Compensation expense for these awards is measured and recognized as wages and benefits in the consolidated statements of operations on a straight-line basis over the vesting period.

Fair Value

Fair value for the measurement of financial assets and liabilities is defined as the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. The Company utilizes a valuation hierarchy for disclosure of the inputs for fair value measurement. This hierarchy prioritizes the inputs into three broad levels as follows:

Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 inputs are quoted prices for identical or similar assets or liabilities in less active markets or model-derived valuations in which significant inputs are observable for the asset or liability, either

directly or indirectly through market corroboration, for substantially the full term of the financial instrument.

Level 3 inputs are unobservable inputs based on the Company's assumptions used to measure assets and liabilities at fair value.

The estimated fair values of the Company's financial instruments have been determined by the Company using available market information and valuation methodologies. The carrying value of the Company's cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate fair market value due to the relatively short period of time to maturity. The carrying value of the Company's revolving credit facility approximates fair value, as outstanding advances at December 31, 2016 bear interest based on current market rates as defined in the credit facility.

As of December 31, 2016, the carrying value of the Company's long-term debt and related accrued interest was $40,000 and $4,245, respectively, with a total estimated fair value of $52,919. The Company estimated the fair value of the debt using a discounted cash flow model which includes the instrument's term, notional amount and discount rate. These fair value measurements are considered Level 3, as significant inputs to the fair value calculation are unobservable in the market.

Concentration of Credit Risk and Significant Customers

The Company has no significant off-balance sheet risk such as foreign exchange contracts, option contracts or other hedging arrangements. Financial instruments that potentially expose the Company to concentrations of credit risk consist mainly of cash and cash equivalents and accounts receivable. The Company maintains its cash and cash equivalents principally in accredited financial institutions of high credit standing. The Company routinely assesses the credit worthiness of its customers and generally has not experienced any material losses related to receivables from individual customers or groups of customers. The Company does not generally require collateral. Due to these factors, no credit risk beyond amounts provided for collection losses is believed by management to be probable in our accounts receivable, net.

The Company had one customer that represented 22% and 18% of revenue for the years ended December 31, 2016 and 2015, respectively. This customer also represented 28% and 19% of accounts receivable at December 31, 2016 and 2015, respectively. The Company had one customer that represented 17% of revenue and another customer represented 11% of revenue for the year ended December 31, 2014.

Recent Accounting Pronouncements

In October 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-16, Income Taxes (Topic 740): Intra-entity Transfers of Assets Other Than Inventory. This ASU requires entities to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. This ASU, which requires modified retrospective application through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption, is effective for annual reporting periods beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact this ASU will have on its consolidated financial statements.

Note 2. Summary of Significant Accounting Policies (Continued)

In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. This ASU simplifies various aspects related to how share-based payment transactions are accounted for and presented in the financial statements, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This ASU requires prospective, retrospective, or modified retrospective application, depending on the amendment, and is effective for annual reporting periods beginning after December 15, 2017, with early adoption permitted. The Company is currently evaluating the impact this ASU will have on its consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which provides guidance for revenue recognition. This ASU will supersede the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance. It also supersedes some cost guidance included in Subtopic 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts. The standard can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption and is effective for annual reporting periods beginning after December 15, 2018. In 2016, there were four ASUs issued to clarify or provide technical corrections and improvements to ASU No. 2014-09. The clarifications include reporting revenue gross versus net, identifying performance obligations and licensing, narrow-scope improvements and practical expedients, and technical corrections and improvements. The Company is currently evaluating the impact all of these ASUs will have on its consolidated financial statements.

Note 8. Restructuring

During 2016, 2015 and 2014, the Company continued efforts to restructure certain acquired operations, primarily in the research and development areas in the US, Canada, Europe, Asia and the Middle East. This resulted in several restructuring initiatives related to facilities and human capital to align operations with Company business requirements. The Company recorded restructuring expense related to the costs arising from these decisions which included the cost of terminating leases, costs associated with the consolidation of facilities and the elimination of various workforce positions. The Company accounts for workforce termination costs in accordance with ASC 712—"Non-retirement post-employment benefits". In accounting for these obligations, the Company is required to make assumptions related to the amounts of employee severance, benefits, and related costs and the time period over which leased facilities will remain vacant, sublease terms, sublease rates and discount rates. Estimates and assumptions are based on the best information available at the time the obligation arises. These estimates are reviewed and revised as facts and circumstances dictate. Changes in these estimates could have a material effect on the amount accrued on the consolidated balance sheet. The assessment activities are ongoing and may result in further restructuring and related charges, the amount and timing of which cannot be determined at this time.

A summary of changes in the restructuring accrual is as follows:

|  | Facilities-related |  | Workforce reduction |  | Total |
--- | --- | --- | --- | --- | --- | --- | ---
Liability as of January 1, 2014 |  | $ | 1,438 |  | $ | 2,828 |  | $ | 4,266 |

Note 9. Liquidity and Borrowings

Liquidity

The Company had net cash flows provided by operations of $5,361 during 2016 compared to cash used in operations of $35,628 in 2015. The increase in cash flows from operations in 2016 of $40,989 is primarily due to operational efficiencies and an overall increase in gross profit. As of December 31, 2016, the Company had a cash balance of $32,759 and borrowings available under its revolving credit line of $30,767. As of December 31, 2016, the Company had long-term related party borrowings outstanding of $40,000 and $17,000 under the revolving credit line. The revolving credit line outstanding balance and availability is subject to a Credit Agreement with Silicon Valley Bank as lead agent, which has a term expiring July 1, 2019. The $40,000 long-term related party debt is due on September 30, 2019 and is subordinate to the borrowings outstanding under the revolving line of credit. Based on the Company's financial condition at December 31, 2016 and current and anticipated future operations, the Company believes that its available cash, anticipated cash flow from operations and available borrowings under its revolving line of credit are sufficient to fund working capital and capital expenditure requirements for at least the next 12 months from the date of this report.

Revolving Credit Facility with Silicon Valley Bank

Effective July 1, 2016, two of the Company's operating subsidiaries, with the Company as guarantor, entered into a Senior Secured Credit Agreement with Silicon Valley Bank ("SVB") ("the SVB Agreement"). The SVB Agreement, with a maturity date of July 1, 2019, provides for revolving loans, including letters of credit, not to exceed $50,000 in total, with a potential further increase available for a total revolving line of credit up to $75,000. Borrowing availability is determined monthly based on the amount of collateralized eligible trade accounts receivable. Both Alternate Base Rate ("ABR") and Eurodollar loans are available under the facility. ABR loans bear interest based on the higher of the Prime Rate and the Federal Funds Effective Rate, plus 0.5% and an applicable margin that varies according to the amount of borrowings available. Eurodollar loans bear interest based on LIBOR plus an applicable margin that varies according to the amount of borrowings available. In the event of a default, the annual interest rates would increase by 2%.

Note 9. Liquidity and Borrowings (Continued)

In conjunction with the SVB Agreement, the Company incurred $1,428 in debt issuance costs. These debt issuance costs are included in other assets in the consolidated balance sheets and are being amortized over the remaining life of the SVB Agreement using the straight line method. As of December 31, 2016, the unamortized debt issuance costs totaled $1,215. Amortization of debt issuance costs are included in interest expense in the consolidated statements of operations and totaled $217 for the year ended December 31, 2016.

The SVB Agreement requires the Company to comply with certain representations, warranties, periodic reporting and financial covenants, including maintaining a minimum free cash flow and minimum liquidity. As of December 31, 2016, the Company was in compliance with all covenants related to the SVB Agreement.

As of December 31, 2016, the Company had borrowings and letters of credit outstanding under the SVB Agreement of $17,000 and $2,233, respectively. The availability remaining under the revolving credit line was $30,767 as of December 31, 2016.

Long-Term Debt, Related Party

In 2015, the Company entered into a Subordinated Term Loan Agreement ("Subordinated Term Loan") with OEP Parent, a related party. The Subordinated Term Loan bears interest at 10%, compounding quarterly, with a maturity date of September 30, 2019. As of December 31, 2016, there were borrowings outstanding of $40,000, with no additional available borrowing capacity. Borrowings under the Subordinated Term Loan are unsecured and are subordinate to the Company's Revolving Credit Facility. No prepayment of the Subordinated Term Loan is allowed per the SVB Agreement until the SVB Agreement expires. Upon the occurrence of an Event of Default as defined, the interest rate would increase to 12%.

In 2013, the Company entered into the Third Amendment to the Amended and Restated Loan and Security Agreement with Comerica Bank (collectively the "Comerica Agreement") which established a $16,000 term loan payable in 36 monthly installments of $444 commencing August 1, 2013. The term loan proceeds were used to pay or refinance the purchase price and related fees and expenses in connection with the Company's July 1, 2013 acquisition of the assets of Ventraq Inc. The Comerica Agreement also provided for an increase to the Company's then existing revolving credit line (inclusive of the term loan balance) from $35,000 to $40,000, with a further increase available for a total revolving line of credit of up to $50,000. Outstanding advances bore interest based on the prime rate as defined in the Comerica Agreement plus an applicable margin of 1.75%, and were collateralized by certain assets of the Company. The Comerica Agreement matured on July 1, 2016 and consequently, there were no borrowings outstanding under the revolving credit line at December 31, 2016.

Purchase Commitments

In the normal course of business, the Company enters into commitments to purchase goods and services over a fixed period of time. If the Company does not meet these specified purchase commitments, it could be required to purchase the inventory, or in the case of certain agreements, pay an early termination fee. In certain instances, the Company is permitted to cancel, reschedule or adjust these orders. Consequently, only a portion of the amount reported as purchase commitments relates to firm, non-cancelable and unconditional obligations.

As of December 31, 2016, minimum contractual commitments for supplier contracts and software licensing agreements having an initial or remaining non-cancelable term in excess of one year are $5,314, $4,715, $4,335, $765 and $0 for 2017, 2018, 2019, 2020 and 2021, respectively.

Legal Proceedings

The Company is routinely subject to legal proceedings and claims arising in the ordinary course of business. The Company's management does not expect that the outcome in any of these legal proceedings, individually or collectively, will have a material adverse effect on the Company's financial position, results of operations or cash flows.

The Company recognizes legal fees as incurred when the legal services are provided. For the years ended December 31, 2016, 2015 and 2014, legal costs of $11,391, $22,223 and $4,078, respectively, were incurred related to three lawsuits. The first complaint was filed by the Company on January 23, 2014 alleging that Metaswitch Networks Ltd. and Metaswitch Networks Corp. ("Metaswitch") infringed on certain patents owned by the Company. Following unsuccessful mediation, a trial took place and the Company was initially awarded approximately $8,200 in past royalty damages on January 15, 2016. On September 29, 2016, the Court confirmed the jury verdict following motions from both parties. The Company is seeking royalty income and other damages and has appealed a ruling of the Court denying an injunction for continued infringement by Metaswitch. Due to the uncertainties surrounding the ultimate outcome, the Company has not recognized awards in the case as income in its financial statements for the years ended December 31, 2016, 2015 or 2014. A second lawsuit was filed on July 7, 2014, between the Company and Metaswitch in which both parties asserted further claims of patent

infringement against each other. The trial for the second lawsuit concluded on March 17, 2016 with no damages awarded to either party. On June 2, 2016, a third lawsuit was filed that involves consolidating various non-patent claims and counterclaims that were severed from the first two lawsuits and the trial is currently expected to begin in the second half of 2017.

Note 12. Stockholders' Deficit

On July 30, 2013, the Articles of Association ("Articles") were amended and adopted by special resolution at an extraordinary general meeting of the shareholders of the Company and the Fifth Amended and Restated Stockholders Agreement ("Stockholders Agreement") was executed. Among other things, the Articles identify four Classes of Shares that are designated as Class A, B, C and E Shares. The Articles provide that following a Realization Event, all issued and outstanding shares of stock will be automatically converted into Class D Shares. A Realization Event is defined in the Articles as any voluntary or involuntary liquidation, dissolution or winding up of the Company; mergers or consolidations in which majority voting power is lost; the sale, lease, transfer, exclusive license or other disposition of the assets of the Company to a third party; or a public offering providing an amount of funds for distribution that would provide holders of Class C Shares cash distributions at least as great as their then-existing Class C Accreted Amount. Class A and C Shares are identified as voting shares of the Company and, subject to applicable law, Class B and E Shares are identified as non-voting shares. At the extraordinary general meeting of the shareholders, the shareholders approved an ordinary resolution granting authority to the Board to issue Class E Shares.

Class E Shares

In July 2013, the Board approved the 2013 Equity Incentive Plan (the "Plan") which granted stock based compensation awards of Class E Shares to designated participants. All share-based compensation awards are subject to restrictions and other provisions contained in the Plan and the applicable award agreement. The aggregate number of shares of stock available for issuance under the Plan is 752,947,156 Class E Shares. All Class E Shares have a par value of $0.00001 per share. In 2016, 2015 and 2014, the Company issued 70,777,034, 17,317,785 and 28,611,992 Class E Shares to designated Participants of the Plan, respectively. Shares repurchased during 2016, 2015 and 2014 in accordance with the Plan provisions totaled 18,823,683, 60,784,797 and 35,890,480 respectively. Class E Shares outstanding as of December 31, 2016 totaled 693,166,280.

Class C Shares—Redeemable Preferred Stock

On December 19, 2012, the Company issued 4,872,903,160 shares of GENBAND Holdings Class C Shares to One Equity Partners III, L.P. and certain affiliated entities (collectively, "OEP"), a direct majority stockholder, in exchange for the extinguishment and termination of all of the obligations under a then pre-existing credit agreement with OEP (the "OEP Debt Agreement"). As a result, the Company's authorized capital was increased from 5 billion to 10 billion shares with a par value of US $0.00001 per share; Class C Shares were authorized; and following a Realization Event, if applicable, all issued and outstanding shares of stock are to convert to Class D Shares.

The Class C accretes value at 13% per annum and such accretion is reported in the consolidated statements of changes in convertible preferred stock and stockholders' deficit as the accretion of

Note 12. Stockholders' Deficit (Continued)

convertible preferred stock and is equal to the initial amount of $0.070486161 per share plus accretion at 13% per annum, accreting daily and compounding annually. The Class C accreted value is reduced for cash dividends paid or tax distributions. When and if declared at each quarterly determination date, a quarter's accretion value may be paid as a cash dividend to the Class C stockholders. No dividends were paid or declared for the years ended December 31, 2016, 2015 or 2014.

The Company adopted the reporting requirements of ASR 268 (Securities and Exchange Commission Financial Reporting Codification, SEC. 211, Redeemable Preferred Stocks) which changed the manner in which it accounts for Class C convertible preferred stock. As a result, the Company retrospectively reclassified the Class C Shares from permanent stockholder's deficit to mezzanine equity and recorded its accretion as an increase in Class C convertible preferred stock and a decrease in additional paid-in capital. Additionally, the Class C Shares are now presented in the accompanying consolidated balance sheets at the liquidation preference at December 31, 2016, 2015 and 2014. Previously, the Class C Shares were presented in the consolidated balance sheets at $343,472, which represented the fair value on the issuance date of December 19, 2012.

The following list of actions, among others, by the Company require the approval of the holders of at least a majority of the outstanding Class C Shares: issuance of additional preferred shares ranking pari passu or senior to Class C Shares, share repurchases or redemptions by the Company, incurrence of indebtedness (other than trade indebtedness) and the consummation of any change of control or public offering in which Class C stockholders would not receive cash distributions at least equal to Class C accreted value. The Company has a call right, subject to the consent of a majority of the holders of the Class C Shares, to purchase on a pro rata basis, some or all of the Class C Shares at any time at the Class C accreted amount. The Company had a one-time right to repurchase up to $100,000 of Class C Shares (based on accreted value) by paying an annually increasing repurchase premium ranging from 6% to 37.5% of the Class C accreted value. Such one-time repurchase right expired on December 19, 2016.

In January 2013, in connection with the issuance of Class C Shares in December 2012, the Company offered existing accredited investors that were direct or indirect holders of Class A Shares, the right to purchase Class C Shares (the "Class C Rights Offering"), at the price of $0.070486161 per share. Eligible stockholders could purchase up to their pro-rata portion of available Class C Shares. At the closing of the Class C Rights Offering, pursuant to the Contribution Agreement between the Company and OEP executed December 3, 2012, as amended, OEP surrendered to the Company an equal number of Class C Shares purchased by eligible stockholders in the rights offering and the Company remitted to OEP $0.070486161 per Class C Share in cash. Concurrently with the repurchase of Class C Shares from OEP, the Company issued the Class C Shares to the eligible stockholders participating in the Class C Rights Offering and such eligible stockholders remitted to the Company $0.070486161 per Class C Share in cash. The Class C Rights Offering closed on March 15, 2013 with 34,816,054 Class C Shares repurchased and issued.

Priorities and Dividends

The Articles set forth the following order of priority for dividends and distributions to the Company's stockholders, provided that Step A and Step B will occur simultaneously, after giving effect to all benchmark amounts, as defined:

Step A is defined as first, to the holders of Class C Shares, in an amount equal to the greater of (i) the accreted value of the Class C Shares or (ii) the amount that would be distributed if the Class C accreted share value was converted to Class A Shares at the price of $0.070486161 per share (the liquidation preference); second, to holders of Class A Shares, in proportion to the respective unreturned capital of each member in respect of the Class A Shares until the cumulative dividends and other distributions equals the aggregate amount of all capital contributions made by holders of Class A Shares; and thereafter, to the holders of Class A Shares and Class B Shares pro rata based on the number of such shares held by each holder relative to all of the issued and outstanding shares, provided that distributions shall be adjusted for Class B shareholders who are also Class E shareholders.

Step B is defined as to the holders of Class E Shares, in an amount equal to the total distributions made in respect of Class A, B and C Shares in excess of the benchmark amount (as defined) multiplied by the ratio of Class E Shares held to the total number of Class A, B, C and E Shares outstanding.

Note 13. Equity Incentive Plans

The Company has granted share-based awards under its Equity Incentive Plans (the "New Plans") and its 1999 Stock Option/Stock Issuance Plan (the "Predecessor Plans"). The Predecessor Plans provided for grants of non-qualified or incentive stock options as well as restricted stock awards.

The New Plans

2013 Equity Incentive Plan

In July 2013, the Board approved the 2013 Equity Incentive Plan (the "2013 Plan") which grants stock based compensation awards of Class E Shares to designated participants. All share-based compensation awards are subject to restrictions and other provisions contained in the Plan. The intent is for all Class E Shares to be treated as "profits interests" for United States ("US") federal income tax purposes as of the date such Class E Shares are issued. Any person receiving Class E Shares is required to have made a capital contribution to the Company in the amount of $1 in exchange for Class A Shares and make a timely and effective election under Section 83(b) of the Internal Revenue Code ("Code") with respect to such Class E Shares.

Per the terms of the Class E Share Agreement, the shares are subject to an automatic repurchase right whereby the Company can repurchase, at par value, all Class E Shares not yet vested upon the occurrence of a repurchase trigger as defined. Shares are released from the automatic repurchase right as they become vested. A majority of the Class E Shares outstanding was issued on the 2013 Plan effective date and has been released from the automatic repurchase right as of December 31, 2016.

The aggregate number of shares of stock available for issuance under the 2013 Plan is 752,947,156 Class E Shares. All Class E Shares have a par value of $0.00001 per share. The fair value of the

Class E Shares issued in 2016, 2015 and 2014 was $0.0007, $0.005 and $0.008 per share, respectively. The Class E Shares are being amortized as a component of share-based compensation expense over the vesting period of four years.

A summary of the 2013 Plan activity for non-vested Class E shares for the years ended December 31, 2016, 2015 and 2014 is as follows:

|  | Years Ended December 31, |

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

For the years ended December 31, 2016, 2015 and 2014, Class E Share compensation expense was $978, $1,148, and $1,318, respectively. Total compensation expense related to non-vested awards not yet recognized was $160 as of December 31, 2016 and is expected to be recognized over the weighted average vesting period of 1.47 years or at the occurrence of an IPO or other specified event, whichever is shorter.

2010 Equity Incentive Plan

On November 3, 2010, the Company's Board approved the 2010 Equity Incentive Plan (the "2010 Plan") which provided share-based compensation awards of Class B Shares to designated participants. All share-based compensation awards are subject to restrictions and other provisions contained in the 2010 Plan. Among other things, the 2010 Plan restricts the transferability of all equity instruments of the consolidated group and provides for liquidity upon a change in control and other certain transactions, as defined in the 2010 Plan. The intent was for all Class B Shares to be treated as "profits interest" for US federal income tax purposes as of the date such Class B Shares are issued. Any person receiving Class B Shares was required to make a capital contribution to the Company in the amount of $1 in exchange for Class A Shares and made an election under Section 83(b) of the Code with respect to such Class B Shares.

Per the terms of the Class B Share agreement (the "Class B Agreement"), the shares were subject to an automatic repurchase right whereby the Company could repurchase, at par value, all Class B Shares not yet vested upon the occurrence of a repurchase trigger as defined in the Class B Agreement. As of December 31, 2016, all Class B Shares have been released from the automatic repurchase right.

During 2016, 2015 and 2014, the Company exercised the automatic repurchase rights under the Class B Agreement and repurchased 507,020, 384,524 and 764,647 of non-vested Class B Shares, respectively, from the participants who terminated their employment with the Company. The Company paid par value for these shares.

The aggregate number of shares of stock available for issuance under the 2010 Plan was 136,581,762 Class B Shares with a par value of $0.00001 per share. The Class B Shares were amortized as a component of share-based compensation expense over the vesting period of four years. For the years ended December 31, 2016, 2015 and 2014, Class B Share compensation expense was $294, $274 and $355, respectively.

The Predecessor Plans

Prior to the year 2010, certain employees of the Company, or its predecessor entities, and other individuals participated in employee stock compensation plans generally comprised of stock options and restricted stock. Awards outstanding under such predecessor plans are not material either individually or in the aggregate. For the years ended December 31, 2016, 2015 and 2014, there was no share-based compensation expense related to the stock options and compensation expense related to the restricted stock was insignificant. At December 31, 2016, there were approximately 3.3 million stock options outstanding with a weighted average exercise price of $0.93 and a weighted average remaining contractual life of 0.92 years and there were no restricted stock awards outstanding.

No US federal income tax provision (benefit) is included in the Company's consolidated financial statements related to the income or loss generated by the Company and GENBAND US LLC.

Certain subsidiaries of the Company remain subject to US federal income taxation due to their classification as a corporation under US tax law. Therefore, the current and deferred US federal income tax provision (benefit) for the years ended December 31, 2016, 2015 and 2014 relates entirely to these subsidiaries.

The Company and certain of its subsidiaries are each subject to certain state and local income taxes imposed at the entity level. All of the Company's international subsidiaries are subject to tax in their respective jurisdictions.

The Company has state research and development credit and other state tax credit carryforwards available for use in the Company's state tax returns totaling $1,469 and $1,517 as of December 31, 2016 and 2015, respectively. The credit carryforwards begin to expire in 2025.

The Company has Canadian research and development tax credit carryforwards of $4,838 and $4,219 as of December 31, 2016 and 2015, respectively. These credit carryforwards begin to expire in 2031 and are subject to full valuation allowances as the Company has concluded that it is not more-likely-than-not that these carryforwards will be realized. Future law changes or unexpected changes to the company's business operations may affect the valuation allowances.

The Company also had NOL carryforwards in various states of $5,439 and $3,075 as of December 31, 2016 and 2015, respectively. These carryforwards are subject to full valuation allowances as the Company has concluded that it is not more-likely-than-not that these carryforwards will be realized. These NOL's begin to expire in 2021.

The increase in the Company's valuation allowance of $305 primarily relates to additional Canada research and development credits.

The Company had non-US NOL carryforwards of $4,661 and $4,631 as of December 31, 2016 and 2015, respectively. These NOL carryforwards are mainly related to Brazil and are available for carryforward indefinitely.

The company asserts permanent reinvestment outside the United States of the earnings in its non-US subsidiaries. As such, the Company does not record a deferred tax liability related to bringing these earnings to the United States. If the earnings were distributed back to the United States, there would not be a material impact on the taxes of the Company. However, the Company does not assert permanent reinvestment of the earnings of its non-US subsidiaries inside of their countries of incorporation and those earnings would be available for repatriation to GENBAND Ireland Limited (immediate indirect parent). Consequently, the Company has recorded a deferred tax liability of $1,215 and $826 as of December 31, 2016 and 2015, respectively.

The Company recognizes interest and penalties as a component of its income tax provision (benefit). For the years ended December 31, 2016, 2015 and 2014, interest and penalties were not a material component of the Company's income tax provision (benefit).

The Company does not anticipate a material change to its unrecognized tax benefits in the next 12 months. The Company files federal, state and local income tax returns in the United States and in numerous foreign jurisdictions. In general, the Company and its non-US subsidiaries have no open tax years prior to 2011. As of December 31, 2016, the Company has ongoing income tax audits in certain foreign countries. The Company believes that an adequate provision has been made for any adjustments that may result from tax examinations.

Note 15. Employee Retirement Benefit Plans

Defined Contribution Plans

The Company has established a defined contribution savings plan under Section 401(k) of the Code, whereby substantially all employees in the United States may contribute a percentage of their compensation on a tax-deferred basis. The Company sponsors defined contribution plans covering

substantially all employees in various international locations to which the employees may make contributions. The Company generally contributes amounts sufficient to satisfy the minimum amount required by applicable law and regulations in each country. For the years ended December 31, 2016, 2015 and 2014, the Company contributed $2,415, $4,683 and $5,195, respectively, to the defined contribution plans.

Non-US Defined Benefit Plans

Several subsidiaries of the Company sponsor certain retirement benefit programs covering employees in various international locations that are considered to be defined benefit pension plans for accounting purposes. The Company's general funding policy with respect to the qualified pension plans is to contribute amounts at least sufficient to satisfy the minimum amount required by applicable law and regulations, or to directly pay benefits where appropriate. Benefits under the defined benefit plans are typically based either on years of service and the employee's compensation (generally during a fixed number of years immediately before retirement) or on annual credits. The range of assumptions that are used for the non-US defined benefit plans reflect the different economic environments within the various countries.

The Company defers all actuarial gains and losses resulting from variances between actual results and economic estimates or actuarial assumptions. The unrecognized actuarial gains and losses are recorded as unrealized pension actuarial gain (loss) in accumulated other comprehensive loss. For defined benefit pension plans, these unrecognized gains and losses are amortized as a component of net periodic benefit cost when the net gains and losses exceed 10% of the greater of the market-related value of plan assets or the projected benefit obligation at the beginning of the year. Amortization of accumulated other comprehensive loss, net into net periodic benefit cost in 2017 is expected to be $106.

The principal weighted average assumptions used to determine benefit obligation are as follows:

|  | December 31, |
--- | --- | --- | ---
|  | 2016 |  | 2015 |
Discount rate |  |  | 1.41 | % |  | 1.97 | %
Rate of compensation increase |  |  | 3.39 | % |  | 3.33 | %

The principal weighted average assumptions used to determine net periodic benefit cost are as follows:

|  | Years Ended December 31, |
--- | --- | --- | ---
|  | 2016 |  | 2015 |  | 2014 |
Discount rate |  |  | 1.97 | % |  | 1.78 | % |  | 3.29 | %
Expected long-term return on plan assets |  |  | 1.63 | % |  | 1.49 | % |  | 3.08 | %
Rate of compensation increase |  |  | 3.33 | % |  | 3.30 | % |  | 3.39 | %

Assumed discount rates are used in measurements of the projected, accumulated and vested benefit obligations and the service and interest cost components of net periodic pension cost. Estimated discount rates reflect the rates at which the pension benefits could be effectively settled. The Company determines the discount rates of the plans in the Euro zone using the iBoxx Euro Corporate AA Bond indices with appropriate adjustments for the duration of the plan obligations. In other international locations, the Company determines the discount rates based primarily on local AA-AAA rated Corporate Bond Indices and the Citigroup Pension Discount Curve with the duration appropriate to the duration of the plan obligations.

Note 15. Employee Retirement Benefit Plans (Continued)

The plans in the Netherlands and Switzerland are funded through insurance contracts, which provide guaranteed interest credit. The fair value of the contract is derived from the insurance company's assessment of the minimum value of the benefits provided by the insurance contract. The methodology used to value the plan assets assumes that the value of the plan assets equals the guaranteed insured benefits. For consistency, the same discount rate used in the valuation of the benefit obligations is used to place a value on the plan assets. The assets are assumed to grow each year in line with the discount rate, and therefore, the expected return on the assets is set equal to the discount rate.

The Company utilizes a valuation hierarchy discussed in Note 2 for disclosure of the inputs for fair value measurement of the plan assets. The fair value of the combined plan assets are as follows:

|  | December 31, 2016 |  | December 31, 2015 |

During the year ended December 31, 2016, certain employees in the Netherlands and Switzerland made total contributions of $37 to the respective pension plans. Employee contributions for these plans are based on a fixed 5% of the relevant pensionable earnings. The Company funds these plans by contributing at least the minimum amount required by applicable regulations and as recommended by an independent actuary. During the year ended December 31, 2016, the Company contributed $112 to its pension plans and expects to contribute $144 to its pension plans in 2017.

Note 20. Subsequent Events (Continued)

2017, the Company filed a petition against Metaswitch in the District Court of Dallas County, Texas (134th Judicial District) ("the Texas State Court"), asserting the claims the Company had previously asserted in the Federal District Court action. Metaswitch filed its answer on April 21, 2017 and asserted counterclaims against the Company. The Texas State Court issued a scheduling order setting trial for this case in April 2018.

Additionally, on March 29, 2017, Metaswitch filed a petition in Superior Court of the State of California, County of Santa Clara ("the California State Court") seeking declaratory judgment regarding the Company's trade secret misappropriation claims previously asserted in the Federal District Court action that was dismissed. Metaswitch also asserts claims of common law unfair competition and tortious interference with a prospective business relationship against the Company. The parties are now awaiting a decision from the California State Court. At this time, it is not possible to predict the outcome, including whether or not any proceedings will continue, and when or how the matter will be resolved. Therefore, an estimate of the possible range of loss, if any, cannot be made.

On May 23, 2017, the Company, GENBAND Inc. ("GB"), GENBAND II, Inc. ("GB II") and Sonus Networks, Inc. ("Sonus") entered into an Agreement and Plan of Merger ("the Merger Agreement"). Pursuant to the Merger Agreement, all issued and outstanding shares of the Company (other than shares of capital stock or other equity interests of the Company owned by the Company, GB or GB II) will be converted into shares of a newly formed company ("Newco"), and shareholders of the Company will have a right to receive a three-year promissory note issued by Newco having an aggregate principal amount of $22.5 million. Upon the consummation of the transactions contemplated by the Merger Agreement, the Company's shareholders will own approximately 50% of the outstanding shares of Newco. The Board of Directors of the Company has unanimously approved the transactions contemplated by the Merger Agreement and the Company has agreed to hold a shareholders' meeting to submit the Merger Agreement to its shareholders for their approval.

performance. GENBANDCare services include managing software updates, hardware maintenance, hardware repair services and managed spares programs and emergency assistance during disaster recovery.

Note 2. Summary of Significant Accounting Policies

Basis of Presentation

The consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America ("US GAAP") for all periods presented. The year-end balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America.

Principles of Consolidation

The consolidated financial statements of the Company include all majority owned subsidiaries and assets and liabilities of GB Holdings. All intercompany transactions between and among the Company and its subsidiaries have been eliminated.

Use of Estimates

The preparation of consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the amounts reported. Estimates and judgments relied upon in preparing these consolidated financial statements include revenue recognition for multiple element arrangements, accrued warranty, income taxes, depreciation, amortization, employee benefits, share-based compensation, contingencies, inventory, intangible assets and liability valuations. The Company regularly assesses these estimates and records changes in estimates in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that the Company believes to be reasonable under the circumstances. Actual results may or may not differ from those estimates.

Cash and Cash Equivalents

Cash and cash equivalents include cash deposited with financial institutions and liquid investments with original maturity dates equal to or less than three months. The Company holds cash and cash equivalents at major financial institutions, which often exceed Federal Deposit Insurance Corporation insured limits. Historically, the Company has not experienced any losses due to such bank depository concentration.

Foreign Currency Translation

The Company's consolidated financial statements are presented in US dollars ("USD"). The Company has reviewed the functional currency for all international operations in order to evaluate the appropriate functional currency for each location. This determination was made by assessing each of the foreign entities and the nature of their operations. After evaluating the relevant economic factors,

FIN-49

Table of Contents

(In thousands, except share information)

(Unaudited)

Note 2. Summary of Significant Accounting Policies (Continued)

the Company concluded that the operations in each of the foreign locations are relatively self-contained and integrated within their own particular country or economic environment, thus leading to the conclusion that the local currency should also be the functional currency. All foreign currency statements are translated from their functional currency into USD at the exchange rates in effect at the balance sheet dates for all assets and liabilities and at average rates for all revenue and expenses. The unrealized gains and losses on the net investment in these foreign operations are accumulated as a component of accumulated other comprehensive loss.

Foreign currency translation adjustments of $2,984 and $(433) were recorded in other comprehensive loss for the three months ended June 30, 2017 and 2016, respectively. The loss (gain) on foreign currency exchange transactions of $4,450 and $(931) was recorded in other expense, net for the three months ended June 30, 2017 and 2016, respectively. The loss on foreign currency exchange transactions of $5,764 and $2,733 was recorded in other expense, net for the six months ended June 30, 2017 and 2016, respectively.

Revenue Recognition

The Company derives revenue from the sales of telecommunications hardware and software products, complex customized solutions, and services, including post-contractual support, maintenance, installation and training that are generally sold pursuant to a contract. The terms of the contracts, taken as a whole, determine the appropriate revenue recognition models to be applied. Product revenue includes revenue from arrangements with software related services such as engineering, where the services cannot be separated from the arrangement because the services are essential or fair value cannot be established under the software revenue recognition guidance. In addition, product revenue includes all amounts billed to customers related to shipping and handling with the related expense as a component of cost of revenue in the accompanying consolidated statements of operations. Where services are sold stand-alone or can be separated from product sales in a bundled arrangement, service revenue is reported separately in the consolidated statements of operations.

We primarily derive subscription revenue from fees received from customers for time-based license arrangements and CPaaS offerings. We generally invoice subscription agreements in advance over the subscription period. Subscription revenue is generally recognized ratably over the subscription term when all revenue recognition criteria have been met and is included in product revenue in the consolidated statements of operations.

The Company makes significant judgments and estimates to determine revenue to be recognized in any accounting period. Material differences may result in the amount and timing of revenue for any period if the Company makes different judgments or utilizes different estimates. These estimates affect unbilled accounts receivable and deferred revenue in the consolidated balance sheets and total revenue in the consolidated statements of operations. In making these judgments, the Company uses the following assumptions and estimates:

Persuasive evidence of an arrangement. The Company considers a non-cancellable executed agreement (such as a customer purchase order, contract, etc.), or a group of closely-related agreements signed by all parties involved to be persuasive evidence of an arrangement.

Note 2. Summary of Significant Accounting Policies (Continued)

Delivery has occurred. The Company generally considers delivery to have occurred when title to and the risk of loss of the products has passed to the customer and no post-delivery obligations exist, except for support. In instances where there are post-delivery obligations, delivery is deemed to occur when the customer specifications have been met with customer acceptance or delivery of the additional elements has occurred. For arrangements where the criteria for revenue recognition have not been met because legal title or risk of loss on products does not transfer to the customer until final payment has been received or where delivery has not occurred, revenue is deferred to a later period when the outstanding criteria have been met.

Fees are fixed or determinable. The Company assesses whether fees are fixed or determinable at the time of sale. The Company considers the fee to be fixed or determinable if the fees are due within the Company's standard payment terms and the fees are not subject to refund or adjustment. If the arrangement fees are not fixed or determinable, including arrangements with extended payment terms, revenue is recognized as cash is collected.

Collection is probable. The Company evaluates credit worthiness for all customers with significant transactions at the time of the transaction. Collection is deemed probable if the Company expects that the customer will be able to pay amounts under the arrangement as payments become due. If the Company determines that collection is not probable, revenue is deferred and recognized upon cash collection.

Depending on the terms of the contract and types of products and services sold, the Company recognizes revenue following the guidance for multiple-element arrangements and software revenue recognition in addition to the general revenue recognition guidance. Revenues are reduced for returns, allowances, discounts and other offerings in accordance with the agreement terms.

For multiple-element arrangements, the Company separates deliverables into more than one unit of accounting if the delivered item(s) have value to the customer on a stand-alone basis, and delivery of the undelivered item(s) is probable and substantially in the Company's control.

The Company determines the selling price for each deliverable based upon the selling price hierarchy for multiple-deliverable arrangements. Under this hierarchy, the selling price for each deliverable is determined using vendor specific objective evidence ("VSOE") of selling price, if it exists; otherwise selling price is determined based on third-party evidence ("TPE") of selling price. If neither VSOE nor TPE of selling price exist, the Company uses its best estimate of selling price ("BESP") for that deliverable.

VSOE is established by the price charged when the item is sold separately on a stand-alone basis or based on the contractual renewal provision. The Company has VSOE for some, but not all, offerings. In cases where VSOE does not exist, the Company has been unable to establish TPE of selling price because there are relatively few observable competitor transactions along with varying levels of customization of products that make it difficult to compare to competitors' products and services. In determining BESP, the Company considers market conditions as well as entity-specific factors which include the impact to pricing based on geography, the pricing and profit objectives by customer class and region, consideration of any customization needed, the expected technological life,

instances or probability of selling the product/service on a stand-alone basis and the use of third parties, among other factors.

For arrangements without significant customization and where hardware and software components together provide the product's essential functionality, the Company recognizes revenue allocated to delivered items that are not contingent on the future delivery of products, services, or other performance obligations, including where customer-specified return or refund privileges exist. Once the Company allocates revenue to each deliverable, the Company recognizes revenue in accordance with its revenue recognition policy noted herein.

For sales of software and software related services, the Company generally uses the residual method to allocate the arrangement consideration. Under the residual method, the amount of consideration allocated to the delivered items equals the total value of software deliverables less the fair value of the undelivered items. For software arrangements where fair value does not exist for any undelivered item, revenue is not recognized until the earlier of (i) delivery of such item or (ii) when fair value of the undelivered item is established, unless the undelivered item is a service, in which case revenue is recognized as the service is performed under the cumulative catch-up method once the service is the remaining undelivered item.

Service elements are generally recognized according to the proportional performance method. The proportional performance method is used when the provision of services extends beyond an accounting period with more than one performance act, and permits the recognition of revenue ratably over the service period when no other pattern of performance is discernible. The nature of the service contract is reviewed to determine which revenue recognition method best reflects the nature of services performed. Provided all other revenue recognition criteria have been met, the revenue recognition method selected reflects the pattern in which the obligations to the customers have been fulfilled.

Deferred revenue

Deferred revenue in the consolidated balance sheets generally consists of post-contract customer support ("PCS") services that are deferred and recognized over the support term and revenue transactions that have outstanding deliverables. Deferred revenue which is not expected to be recognized over the next 12 months is classified as deferred revenue, net of current portion, in the consolidated balance sheets.

Deferred Costs

The Company defers costs for all customer sales arrangements in which there is a deferral of revenue recognition. Deferred costs consist of direct and associated costs related to the arrangement, such as the cost of the hardware, installation costs, third-party costs and other direct costs associated with the revenue. These costs are deferred up to the fair value of the products or services being sold and are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.

Note 2. Summary of Significant Accounting Policies (Continued)

Goodwill and Intangible Assets

Business combinations have been accounted for using the acquisition method. Accordingly, the Company records the assets acquired and liabilities assumed in business combinations at their respective fair values at the date of acquisition, with any excess purchase price recorded as goodwill. This method also requires, among other things, expensing acquisition and integration costs, capitalization of in-process research and development separate from goodwill at the acquisition date fair value, and accounting for acquisition-related restructuring cost accruals subsequent to the acquisition date. The valuation of intangible assets requires significant estimates and assumptions including, but not limited to, determining the timing and expected costs to complete development projects, estimating future cash flows from product sales, developing appropriate discount rates, estimating probability rates for the successful completion of development projects, continuation of customer relationships and renewal of customer contracts and approximating the useful lives of the intangible assets acquired. Intangible assets, other than goodwill are generally amortized based on the expected pattern of benefit to future periods using estimates of undiscounted cash flows, or on a straight-line basis.

Goodwill has an indefinite useful life and is not amortized, but is evaluated for impairment at the reporting unit level annually, on October 1, or whenever events or changes in circumstances indicate the carrying value may not be fully recoverable. In evaluating whether goodwill is impaired, the Company may first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. If it is determined the two-step quantitative test is necessary, the fair value of the reporting unit to which the goodwill is assigned is compared to the reporting unit's carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill is not considered impaired. If the carrying amount of the reporting unit exceeds its fair value, the second step of the goodwill impairment test is performed to measure the amount of impairment loss, if any. The second step of the goodwill impairment test compares the implied fair value of the reporting unit's goodwill with the carrying amount of that goodwill. The implied fair value of goodwill is determined by performing an assumed purchase price allocation, using the reporting unit fair value (as determined in Step 1) as the purchase price. If the carrying amount of goodwill exceeds the implied fair value, an impairment loss is recognized in an amount equal to that excess. Determining the fair value of reporting units requires management to make a number of judgments about assumptions and estimates that are highly subjective and that are based on unobservable inputs. The actual results may differ from these assumptions and estimates, and it is possible that such differences could have a material impact on the Company's consolidated financial statements.

Long-lived assets, including intangible assets other than goodwill, are evaluated for impairment whenever events or changes in circumstances indicate that the net book value of an asset may not be fully recoverable. When such qualitative factors and circumstances exist, the Company compares the projected undiscounted future cash flows associated with related groups of assets over their estimated useful lives against their respective carrying amounts. Impairment, if any, is based on the excess of the carrying amount over the fair value of those assets and is recorded in the period in which the

determination was made. The Company's estimate of future cash flows requires significant judgments and assumptions which may vary from actual cash flows.

Contingent Consideration

Contingent consideration, which includes earnout payments in connection with certain acquisitions, is recognized at fair value on the acquisition date and remeasured each reporting period with subsequent adjustments recognized in the Company's consolidated statements of operations. Changes in the fair value of contingent consideration liabilities may result from changes in discount rates, changes in the timing and amount of sales and/or other specific milestone estimates and changes in probability assumptions with respect to the likelihood of achieving the various earnout criteria. These changes could cause a material impact to, and volatility in the Company's operating results. Earnout payments are reflected in cash flows from financing activities and the changes in fair value are reflected in cash flows from operating activities in the consolidated statements of cash flows.

Research and Development Costs

Research and development costs associated with new product software development, improvement of existing products, process improvement and product use technologies are charged to expense in the period in which they are incurred. These costs consist primarily of employee salaries and benefits, occupancy costs, consulting costs and the cost of development equipment and supplies.

Advertising Costs

Advertising costs are expensed as incurred and are recorded within sales and marketing in the accompanying consolidated statements of operations. Advertising costs, primarily consisting of public relations, trade shows and other advertising costs totaled $222 and $526 for the three months ended June 30, 2017 and 2016, respectively and $1,296 and $1,720 for the six months ended June 30, 2017 and 2016, respectively.

Warranty Costs

The Company's products are covered by a standard product warranty that extends for periods typically ranging from one to three years from the date of sale. The Company's accrued warranty reflects estimated material and labor costs for potential or actual product issues in its installed base that are not covered under maintenance contracts but for which the Company expects to incur an obligation. The Company's accrued warranty, classified as accrued expenses on the consolidated balance sheets, was $1,379 and $1,567 as of June 30, 2017 and December 31, 2016, respectively.

Accounts Receivable

Accounts receivable are carried at original invoice amount less an allowance for doubtful accounts that represents an estimate of losses that could result from collection issues. Revenue that has been earned but remains unbilled is recorded as a component of accounts receivable, net. The Company specifically analyzes accounts receivable, customer credit-worthiness, current economic trends and

FIN-54

Table of Contents

Note 2. Summary of Significant Accounting Policies (Continued)

changes in customer payment terms and collection trends when evaluating the adequacy of its allowance for doubtful accounts. The Company writes off accounts receivable balances against the allowance for doubtful accounts, net of any amounts recorded in deferred revenue, when it ceases collection activities. The Company generally does not charge interest on accounts receivable. Any change in the assumptions used in analyzing a specific account receivable may result in the recognition of an additional provision for doubtful accounts during the period in which the change occurs. The Company does not have any off-balance sheet credit exposures related to its customers.

Inventory

Inventory is valued at lower of cost or market. Cost is determined using standard cost, which approximates actual cost on a first-in, first-out basis. On an ongoing basis, inventory is reviewed and written down for estimated obsolescence or unmarketable inventory equal to the difference between the costs of inventory and the estimated net realizable value based upon forecasts for future customer demand and market conditions. Any adjustment to inventory as a result of an estimated obsolescence or net realizable condition is reflected as a component of cost of revenue. At the point of the loss recognition, a new, lower-cost basis for the respective inventory is established, and any subsequent improvements in facts and circumstances do not result in the restoration or increase to create a newly established cost basis.

Property and Equipment

Property and equipment is stated at cost less accumulated depreciation. Depreciation expense is computed using the straight-line basis over the shorter of the estimated useful life or remaining lease term.

Expenditures for repairs and maintenance are charged to expense when incurred while expenditures for major improvements are capitalized and depreciated. Expenditures for major improvements such as leasehold improvements or qualifying internal use software costs, incurred during the application development stage consisting primarily of outside services and purchased software license costs, are capitalized and amortized. Upon retirement or disposition of property and equipment, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is recognized.

The Company also capitalizes certain development costs incurred in connection with its CPaaS. These capitalized costs are primarily related to the Company's development of its CPaaS communications platform that is hosted by the Company and accessed by its customers on a subscription basis. Costs incurred in the preliminary stages of development are expensed as incurred. Once an application has reached the development stage, direct internal and external costs are capitalized until the software is substantially complete and ready for its intended use. Capitalized software development costs are amortized into cost of revenue on a straight-line basis over the estimated useful life of the related technology, generally two years.

Income Taxes

The Company accounts for income taxes under the asset and liability method prescribed by accounting guidance. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. The Company periodically assesses the recoverability of its deferred tax assets based upon expected future earnings, future deductibility of the asset, and changes in applicable tax laws and other factors. If the Company determines that it is more likely than not the deferred tax asset will not be fully recoverable against future taxable income, a valuation allowance may be established for the difference between the asset balance and the amount expected to be recoverable in the future. The allowance will result in a charge to the Company's consolidated statements of operations. Further, the Company records its income taxes receivable and payable based upon its estimated income tax liability.

The Company accounts for uncertain tax positions, if any, utilizing the two-step approach. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, based on the technical merits of the position. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. A liability is recorded (or a tax related asset is reduced) for the unrecognized tax benefits when a tax position does not meet these criteria. The Company recognizes interest income, interest expense and penalties related to unrecognized tax benefits in income tax (benefit) provision in the consolidated statements of operations.

Defined Benefit Plans

The Company recognizes retirement benefit assets or liabilities in the consolidated balance sheets reflecting the funded status of pension and other retirement benefit plans. Retirement benefit assets and liabilities are adjusted for the difference between the benefit obligations and the plan assets at fair value (measured at year end), with the offset recorded directly in stockholders' deficit through accumulated other comprehensive loss, net of tax. The amount recorded in stockholders' deficit represents the after-tax unamortized actuarial gains or losses, unamortized transition obligations and unamortized prior service costs.

Share-Based Compensation

The Company measures and recognizes compensation expense for share-based awards based on estimated fair values on the date of grant using the Black-Scholes option-pricing model. This model is affected by the Company's calculated stock price as well as estimates regarding a number of variables, including expected stock price volatility over the expected term of the award. Compensation expense for these awards is measured and recognized as wages and benefits in the consolidated statements of operations on a straight-line basis over the vesting period.

Note 2. Summary of Significant Accounting Policies (Continued)

Fair Value

Fair value for the measurement of financial assets and liabilities is defined as the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. The Company utilizes a valuation hierarchy for disclosure of the inputs for fair value measurement. This hierarchy prioritizes the inputs into three broad levels as follows:

Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 inputs are quoted prices for identical or similar assets or liabilities in less active markets or model-derived valuations in which significant inputs are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument.

Level 3 inputs are unobservable inputs based on the Company's assumptions used to measure assets and liabilities at fair value.

The estimated fair values of the Company's financial instruments have been determined by the Company using available market information and valuation methodologies. The carrying value of the Company's cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate fair market value due to the relatively short period of time to maturity. The carrying value of the Company's revolving credit facility approximates fair value, as outstanding advances bear interest based on current market rates as defined in the credit facility.

As of June 30, 2017, the carrying value of the Company's long-term debt and related accrued interest was $40,000 and $6,443, respectively, with a total estimated fair value of $53,805. The Company estimated the fair value of the debt using a discounted cash flow model which includes the instrument's term, notional amount and discount rate. These fair value measurements are considered Level 3, as significant inputs to the fair value calculation are unobservable in the market.

Concentration of Credit Risk and Significant Customers

The Company has no significant off-balance sheet risk such as foreign exchange contracts, option contracts or other hedging arrangements. Financial instruments that potentially expose the Company to concentrations of credit risk consist mainly of cash and cash equivalents and accounts receivable. The Company maintains its cash and cash equivalents principally in accredited financial institutions of high credit standing. The Company routinely assesses the credit worthiness of its customers and generally has not experienced any material losses related to receivables from individual customers or groups of customers. The Company does not generally require collateral. Due to these factors, no credit risk beyond amounts provided for collection losses is believed by management to be probable in our accounts receivable, net.

The Company had two customers that represented 10% or more of our revenue in the three and six months ended June 30, 2017 and 2016. One customer represented 19% and 21%, and another

customer represented 11% and 11% for the three months ended June 30, 2017 and 2016, respectively. One customer represented 16% and 18%, and another customer represented 10% and 13% for the six months ended June 30, 2017 and 2016, respectively.

Recent Accounting Pronouncements

In January 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04") which removes the requirement to compare the implied fair value of goodwill with its carrying amount as part of step 2 of the goodwill impairment test. As a result, under ASU 2017-04, an entity should perform its goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. In addition, ASU 2017-04 clarifies the requirements for excluding and allocating foreign currency translation adjustments to reporting units in connection with an entity's testing of reporting units for goodwill impairment; clarifies that an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable; and makes minor changes to other related guidance within the Accounting Standards Codification ("ASC"). ASU 2017-04 is effective prospectively for us beginning January 1, 2021, with early adoption permitted for goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the impact this ASU will have on its consolidated financial statements.

In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-entity Transfers of Assets Other Than Inventory. This ASU requires entities to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. This ASU, which requires modified retrospective application through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption, is effective for annual reporting periods beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact this ASU will have on its consolidated financial statements.

In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. This ASU simplifies various aspects related to how share-based payment transactions are accounted for and presented in the financial statements, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This ASU requires prospective, retrospective, or modified retrospective application, depending on the amendment, and is effective for annual reporting periods beginning after December 15, 2017, with early adoption permitted. The Company is currently evaluating the impact this ASU will have on its consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). This new standard requires lessees, among other things, to recognize lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under previous authoritative guidance and introduces new disclosure requirements for leasing arrangements. ASU 2016-02 will be effective for the Company

beginning in the year ended December 31, 2020, but early application is permitted. The standard must be adopted using a modified retrospective transition, and provides for certain practical expedients. The Company is currently evaluating the impact this ASU will have on its consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which provides guidance for revenue recognition. This ASU will supersede the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance. It also supersedes some cost guidance included in Subtopic 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts. The standard can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption and is effective for annual reporting periods beginning after December 15, 2018. In 2016, there were four ASUs issued to clarify or provide technical corrections and improvements to ASU No. 2014-09. The clarifications include reporting revenue gross versus net, identifying performance obligations and licensing, narrow-scope improvements and practical expedients, and technical corrections and improvements. The Company is currently evaluating the impact all of these ASUs will have on its consolidated financial statements.

Note 3. Proposed Merger

On May 23, 2017, the Company, GENBAND Inc. ("GB"), GENBAND II, Inc. ("GB II") and Sonus Networks, Inc. ("Sonus") entered into an Agreement and Plan of Merger ("the Merger Agreement"). Pursuant to the Merger Agreement, all issued and outstanding shares of the Company (other than shares of capital stock or other equity interests of the Company owned by the Company, GB or GB II) will be converted into shares of a newly formed company ("Newco"), and shareholders of the Company (other than GB or GB II) will have a right to receive a three-year promissory note issued by Newco having an aggregate principal amount of $22.5 million. Upon the consummation of the transactions contemplated by the Merger Agreement, the Company's shareholders will own approximately 50% of the outstanding shares of Newco. The Board of Directors of the Company has unanimously approved the transactions contemplated by the Merger Agreement and the Company has agreed to hold a shareholders' meeting to submit the Merger Agreement to its shareholders for their approval.

Acquisition and Integration

Acquisition and integration expenses include those expenses related to acquisitions that would otherwise not have been incurred by the Company. These expenses include professional and services fees, such as legal, audit, consulting, paying agent and other fees. The Company recorded $4,103 in the three and six months ended June 30, 2017 related to the proposed merger with Sonus.

Note 9. Restructuring

During 2017 and 2016, the Company continued efforts to restructure certain acquired operations, primarily in the research and development areas in the US, Canada, Europe, Asia and the Middle East. This resulted in several restructuring initiatives related to facilities and human capital to align operations with Company business requirements. The Company recorded restructuring expense related to the costs arising from these decisions which included the cost of terminating leases, costs associated with the consolidation of facilities and the elimination of various workforce positions. The Company accounts for workforce termination costs in accordance with ASC 712—"Non-retirement post-employment benefits". In accounting for these obligations, the Company is required to make assumptions related to the amounts of employee severance, benefits, and related costs and the time period over which leased facilities will remain vacant, sublease terms, sublease rates and discount rates. Estimates and assumptions are based on the best information available at the time the obligation arises. These estimates are reviewed and revised as facts and circumstances dictate. Changes in these estimates

Revolving Credit Facility with Silicon Valley Bank

Effective July 1, 2016, two of the Company's operating subsidiaries, with the Company as guarantor, entered into a Senior Secured Credit Agreement with Silicon Valley Bank ("SVB") ("the SVB Agreement"). The SVB Agreement, with a maturity date of July 1, 2019, provides for revolving loans, including letters of credit, not to exceed $50,000 in total, with a potential further increase available for a total revolving line of credit up to $75,000. Borrowing availability is determined monthly based on the amount of collateralized eligible trade accounts receivable. Both Alternate Base Rate ("ABR") and Eurodollar loans are available under the facility. ABR loans bear interest based on the higher of the Prime Rate and the Federal Funds Effective Rate, plus 0.5% and an applicable margin

that varies according to the amount of borrowings available. Eurodollar loans bear interest based on LIBOR plus an applicable margin that varies according to the amount of borrowings available. In the event of a default, the annual interest rates would increase by 2%.

In conjunction with the SVB Agreement, the Company incurred $1,479 in debt issuance costs. These debt issuance costs are included in other assets in the consolidated balance sheets and are being amortized over the remaining life of the SVB Agreement using the straight line method. As of June 30, 2017, the unamortized debt issuance costs totaled $1,026. Amortization of debt issuance costs is included in interest expense in the consolidated statements of operations and totaled $126 and $248 for the three and six months ended June 30, 2017, respectively.

The SVB Agreement requires the Company to comply with certain representations, warranties, periodic reporting and financial covenants, including maintaining a minimum free cash flow and minimum liquidity. As of June 30, 2017, the Company was in compliance with all covenants related to the SVB Agreement.

As of June 30, 2017, the Company had borrowings outstanding totaling $19,000, with letters of credit outstanding under the SVB Agreement of $2,261. The availability remaining under the revolving credit line was $10,482 as of June 30, 2017.

Long-Term Debt, Related Party

In 2015, the Company entered into a Subordinated Term Loan Agreement ("Subordinated Term Loan") with OEP Parent LLC ("OEP Parent"), a related party. The Subordinated Term Loan bears interest at 10%, compounding quarterly, with a maturity date of September 30, 2019. As of June 30, 2017, there were borrowings outstanding of $40,000, with no additional available borrowing capacity. Borrowings under the Subordinated Term Loan are unsecured and are subordinate to the Company's Revolving Credit Facility. No prepayment of the Subordinated Term Loan is allowed per the SVB Agreement until the SVB Agreement expires. Upon the occurrence of an Event of Default as defined, the interest rate would increase to 12%.

Revolving Credit Line and Term Debt with Comerica Bank

Through June 30, 2016, the Company had a credit facility with Comerica Bank that included a revolver and a $16,000, three-year term loan that was established in 2013 to effectuate an acquisition. The term loan was payable in 36 monthly installments of $444 commencing in August 2013. On July 1, 2016, the term loan matured and the underlying credit facility, including the revolving credit facility, was terminated in lieu of entering into the SVB Agreement. Consequently, there were no borrowings outstanding under the credit facility with Comerica Bank at December 31, 2016 or June 30, 2017.

Note 12. Commitments and Contingencies

Leases

The Company has entered into leases for office space and office equipment used in its operations with expiration dates ranging from 2017 through 2027.

Rent expense recorded under operating leases was $1,453 and $2,334 for the three months ended June 30, 2017 and 2016, respectively. Rent expense recorded under operating leases was $2,912 and $5,353 for the six months ended June 30, 2017 and 2016, respectively. As of June 30, 2017, the Company had standby letters of credit in the amount of $100 in connection with facility leases.

Future minimum operating lease commitments at June 30, 2017 are as follows:

|  | Minimum Operating Lease Commitments |  | Sublease Income |  | Net Operating Lease Commitments |

Purchase Commitments

In the normal course of business, the Company enters into commitments to purchase goods and services over a fixed period of time. If the Company does not meet these specified purchase commitments, it could be required to purchase the inventory, or in the case of certain agreements, pay an early termination fee. In certain instances, the Company is permitted to cancel, reschedule or adjust these orders. Consequently, only a portion of the amount reported as purchase commitments relates to firm, non-cancelable and unconditional obligations.

Note 12. Commitments and Contingencies (Continued)

As of June 30, 2017, minimum contractual commitments for supplier contracts and software licensing agreements having an initial or remaining non-cancelable term in excess of one year are $1,280, $3,227, $1,817, $63 and $0 for 2017, 2018, 2019, 2020 and 2021, respectively.

Legal Proceedings

The Company is routinely subject to legal proceedings and claims arising in the ordinary course of business. The Company's management does not expect that the outcome in any of these legal proceedings, individually or collectively, will have a material adverse effect on the Company's financial position, results of operations or cash flows.

The Company recognizes legal fees as incurred when the legal services are provided. For the three months ended June 30, 2017 and 2016, legal costs of $456 and $2,251, respectively, were incurred related to three lawsuits. For the six months ended June 30, 2017 and 2016, legal costs of $1,418 and $7,993, were incurred, respectively. The first complaint was filed by the Company on January 23, 2014 alleging that Metaswitch infringed on certain patents owned by the Company. Following unsuccessful mediation, a trial took place and the Company was initially awarded approximately $8,200 in past royalty damages on January 15, 2016. On September 29, 2016, the Court confirmed the jury verdict following motions from both parties. The Company is seeking royalty income and other damages and has appealed a ruling of the Court denying an injunction for continued infringement by Metaswitch. GENBAND appealed the denial of its request for a permanent injunction and presented oral argument on this issue before the U.S. Court of Appeals for the Federal Circuit on June 8, 2017. On July 20, 2017, the U.S. Court of Appeals for the Federal Circuit vacated the lower court's denial of a permanent injunction and remanded the case for further consideration of GENBAND's request for a permanent injunction under the proper legal standard. Due to the uncertainties surrounding the ultimate outcome, the Company did not recognize awards in the case as income in its financial statements for the years ended December 31, 2016 or 2015 or for the six months ended June 30, 2017.

A second lawsuit was filed on July 7, 2014, between the Company and Metaswitch in which both parties asserted further claims of patent infringement against each other. The trial for the second lawsuit concluded on March 17, 2016 with no damages awarded to either party. The court entered a final judgment on April 14, 2016 awarding the Company its costs as the prevailing party. The Company's motion for its costs is pending, as are the parties' motions for judgment as a matter of law and for a new trial.

On June 2, 2016, the Federal District Court issued an order removing a stay and consolidating various non-patent claims and counterclaims that were previously stayed/severed from the first two lawsuits into a third lawsuit. On March 28, 2017, the Federal District Court dismissed this third lawsuit without prejudice for improper subject matter jurisdiction. Immediately following the dismissal of this Federal Court action on March 28, 2017, the Company filed a petition against Metaswitch in Texas State Court asserting the claims the Company had previously asserted in the Federal Court action. Metaswitch filed its answer on April 21, 2017 and asserted counterclaims against the Company. The Texas State Court issued a scheduling order setting trial for this case in April 2018. At this time, it is not possible to predict the outcome, including whether or not any proceedings will continue, and if so,

when or how the matter will be resolved. Therefore, an estimate of the possible range of loss, if any, cannot be made.

Additionally, on March 29, 2017, Metaswitch filed a petition in California State Court, seeking declaratory judgment regarding the Company's trade secret misappropriation claims previously asserted in the Federal Court action that was dismissed. Metaswitch also asserts claims of common law unfair competition, and tortious interference with a prospective business relationship against the Company. Metaswitch filed a request for dismissal of this case on June 29, 2017. The Company is waiting for a Dismissal Order from the California State Court to consider the matter closed.

Note 13. Income Taxes

The Company's income tax (benefit) provision reflects estimates of the effective rates expected to be applicable for the respective full years, adjusted for any discrete events, which are recorded in the period that they occur. These estimates are reevaluated each quarter based on the Company's estimated income tax (benefit) expense for the full year. The estimated effective rates for the three months ended June 30, 2017 and 2016 do not include any benefit for the Company's United States of America partnership losses or zero-rate jurisdictions, as these have no associated tax benefits to the Company. The Company recorded an income tax (benefit) provision of ($1,921) and $816 for the three months ended June 30, 2017 and 2016, respectively, which primarily related to foreign operations. The decrease in 2017 was primarily the result of operating losses in Ireland. The Company recorded an income tax (benefit) provision of ($3,180) and $1,895 for the six months ended June 30, 2017 and 2016, respectively. The decrease in 2017 was primarily the result of operating losses in Ireland.

Note 14. Related Party Transactions

Certain members of the Company's Board and executive management team are on the board of directors of a company that is both a Company customer and vendor. In addition, the Company incurs an annual management fee payable to OEP and has a subordinated term loan payable to OEP. All transactions between the Company and these parties are considered related party transactions in the normal course of business.

Subject to the effect of Applicable Laws, following surrender of any such Certificate, there shall be paid to the holder of the Company Certificates representing whole shares of Company Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of dividends or other distributions, if any, on shares of Company Common Stock with a record date after the Effective Time and theretofore payable with respect to such whole shares of Company Common Stock and not paid, less the amount of any withholding Taxes which may be required thereon, and (ii) at the appropriate payment date, the amount of dividends or other distributions, if any, with a record date after the Effective Time and a payment date subsequent to such surrender, payable with respect to such whole shares of Company Common Stock, less the amount of any withholding Taxes which may be required thereon.

Solstice Common Stock, GB Stock or GB II Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Company or the applicable Surviving Entity, the presented Certificates shall be canceled and exchanged for Company Certificates and cash in lieu of fractional shares, if any, deliverable in respect thereof pursuant to this Agreement in accordance with the procedures set forth in this Article 3.

(f) No fraction of a share of Company Common Stock will be issued in connection with the Mergers, but in lieu thereof each Person otherwise entitled to receive a fraction of a share of Company Common Stock pursuant to Section 3.1(a)(ii), Section 3.1(b)(ii), Section 3.1(c)(ii) or Section 3.1(d)(ii) will be entitled to receive, in accordance with the provisions of this Section 3.2(f), from the Exchange Agent or the Company an amount in cash equal to the product obtained by multiplying (i) the fractional share interest to which such holder would otherwise be entitled pursuant to such Section by (ii) the closing price of a share of Solstice Common Stock on The NASDAQ Stock Market LLC ("NASDAQ") on the last full trading day prior to the Effective Time.

(g) Any portion of the Exchange Fund (including the proceeds of any investments thereof and any shares of Company Common Stock) that remains unclaimed twelve months after the Effective Time shall be delivered to the Company. Any former stockholder of Solstice, Glass, GB or GB II who has not theretofore complied with this Article 3 shall thereafter look only to the Company for payment of their shares of Company Common Stock or cash in lieu of fractional shares and unpaid dividends and distributions on Company Common Stock deliverable in respect of each Certificate such former stockholder or former holder of Glass Shares holds as determined pursuant to this Agreement.

(h) None of the Company, the Surviving Entities, the Exchange Agent or any other person shall be liable to any former holder of Glass Shares or shares of Solstice Common Stock, GB Stock or GB II Stock for any shares of Company Common Stock or cash properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws. If any Certificate shall not have been surrendered prior to seven (7) years after the Effective Time (or immediately prior to such earlier date on which any shares of Company Common Stock or cash payable to the holder of such Certificate pursuant to this Article 3 would otherwise escheat to or become the property of any Governmental Authority), any such shares of Company Common Stock and any such cash shall, to the extent permitted by Applicable Law, become the property of the Company, free and clear of all claims or interest of any person previously entitled thereto.

(i) If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by the Company, the posting by such person of a bond in such reasonable amount as the Company may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the shares of Company Common Stock and cash in lieu of fractional shares, if any, and unpaid dividends and distributions on shares of Company Common Stock deliverable in respect thereof pursuant to this Agreement.

(j) The Exchange Agent shall invest any cash included in the Exchange Fund as directed by the Company on a daily basis; provided, that no such investment or loss thereon shall affect any amounts payable in respect of Solstice Common Stock, Glass Shares, GB Stock or GB II Stock pursuant to Article 2 and the other provisions of this Article 3. Any interest and other income resulting from such investments shall promptly be paid to the Company.

3.3 Treatment of Equity Awards and Equity Plans.

(a) Prior to the Effective Time, Solstice and the Board of Directors or Compensation Committee of Solstice shall take all steps necessary to (i) cause all Solstice Options outstanding as of the date that is five Business Days prior to the Closing Date to (the "Option Vesting Date") become vested in full as of the Option Vesting Date (to the extent not previously vested), (ii) with respect to any Solstice Options that became vested pursuant to Section 3.3(a)(i), permit the holders of such Solstice Options to exercise such awards on or prior to the date that is three Business Days prior to the Closing Date, (iii) cancel, effective as of the end of the day that is three Business Days prior to the Closing Date all Solstice Options outstanding as of such time that have not been exercised, other than Solstice Options granted under the Specified Solstice Plans, and (iv) cause all Solstice Options to otherwise be treated in accordance with this Section 3.3(a). Any Solstice Option under a Specified Solstice Plan that is outstanding as of the end of the day that is three Business Days prior to the Closing Date not be permitted to be exercised between such time and the Effective Time and shall, as of the Effective Time, be assumed by the Company and converted into an option (an "Assumed Company Option") to purchase a number of shares of Company Common Stock (rounded down to the nearest whole share) that is equal to the product obtained by multiplying (i) the number of shares of Solstice Common Stock subject to such Solstice Option as of immediately prior to the Effective Time, by (ii) the Solstice Exchange Ratio, which Assumed Company Option shall have an exercise price per share of Company Common Stock equal to the quotient (rounded up to the nearest whole cent) obtained by dividing (x) the exercise price per share of Solstice Company Stock of such Solstice Option as of immediately prior to the Effective Time by (y) the Solstice Exchange Ratio. Each Assumed Company Option shall otherwise continue to have, and be subject to, the same terms and conditions (including the vesting arrangements and other terms and conditions set forth in the applicable Solstice Stock Plan and the Solstice Option award agreement thereunder) as are in effect immediately prior to the Effective Time, except that the Company or the Board of Directors or Compensation Committee of the Company, as applicable, shall have any and all amendment and administrative authority with respect to such Assumed Company Option (subject, in the case of any amendment, to the required consent, if any, of the affected holder of such Assumed Company Option). The assumption of the Assumed Company Options pursuant to this 3.3(a) shall be undertaken in accordance with Sections 409A and 424 of the Code and the applicable Treasury Regulations thereunder.

(b) Effective as of immediately prior to the Effective Time, (i) each Solstice RSU that is then vested, by its terms (after taking into account any vesting of the Solstice RSU that occurs by reason of the Transactions), will have been settled in shares of Solstice Common Stock and (ii) each Solstice RSU that is not then vested, by its terms (after taking into account any vesting of the Solstice RSU that occurs by reason of the Transactions), as a result of the consummation of the Transactions and settled in shares of Solstice Common Stock shall, at the Effective Time, be assumed by the Company and shall be converted into a new award of restricted stock units of the Company ("Assumed Company RSUs") covering a number of shares of Company Common Stock equal to the product (rounded down to the nearest whole share) of (i) the total number of shares of Solstice Common Stock then underlying such Solstice RSU award multiplied by (ii) the Solstice Exchange Ratio. Subject to the following sentence, each Assumed Company RSU shall otherwise continue to have, and be subject to, the same terms and conditions (including the vesting arrangements (and accelerated vesting arrangements) and other terms and conditions set forth in the applicable Solstice Stock Plan, the Solstice RSU award agreement thereunder and any other Solstice Plan set forth on Schedule 4.11(a) governing such Solstice RSU) as are in effect immediately prior to the Effective Time, except that the Company or the Board of Directors or Compensation Committee of the Company, as applicable, shall have any and all amendment and administrative authority with respect to such Assumed Company RSUs (subject, in the case of any

A-22

amendment, to the required consent, if any, of the affected holder of such Assumed Company RSU).

(c) Effective as of immediately prior to the Effective Time, each Solstice Restricted Share that will not be vested, by its terms (after taking into account any vesting of the Solstice Restricted Share that occurs by reason of the Transactions), as a result of the consummation of the Transactions shall, at the Effective Time, be converted into Company Common Stock pursuant to Section 3.1(a)(ii) and shall otherwise continue to have, and be subject to, the same terms and conditions (including the forfeiture and repurchase restrictions set forth in the applicable Solstice Stock Plan, Solstice Restricted Share award agreement thereunder and any other Solstice Plan set forth on Schedule 4.11(a) governing such Solstice Restricted Share) as are in effect immediately prior to the Effective Time, except that the Company or the Board of Directors or Compensation Committee of the Company, as applicable, shall have any and all amendment and administrative authority with respect to such terms and conditions (subject, in the case of any amendment, to the required consent of the affected holder thereof).

(d) As soon as practicable following the execution of this Agreement, Solstice shall mail to each Person who is a holder of Solstice Options, Solstice Restricted Shares or Solstice RSUs a letter describing the treatment of and payment for such equity awards pursuant to this Section 3.3. On the Option Vesting Date, Solstice shall further notify each holder of a Solstice Option, other than Assumed Company Options, regarding the treatment of his or her Solstice Option set forth in Section 3.3(a) in accordance with the terms and conditions of the applicable Solstice Stock Plan. The forms of such letter shall be provided to Glass for review and comment at least five (5) Business Days prior to distribution and Solstice shall reflect all reasonable comments of Glass thereon to the extent provided within three (3) Business Days following the receipt by Glass of such forms. Solstice acknowledges and agrees that, except as set forth in Sections 3.3(a) through (c), no Solstice Options, Solstice Restricted Shares or Solstice RSUs will be assumed by the Company or otherwise remain outstanding following the Effective Time.

(e) The parties may agree to treat equity compensation held by Solstice employees subject to non-U.S. law in a manner other than that contemplated above in this Section 3.3 to the extent necessary or appropriate to take into account applicable non-U.S. law or Tax or employment considerations.

(f) If the Effective Time occurs on or before the "Purchase Date" relating to the applicable "Offering Period" in effect as of the date of this Agreement (the "Signing Offering Period") (as such terms are defined in the Solstice ESPP) and there are options granted under the Solstice ESPP (the "ESPP Options") then outstanding with respect to the Signing Offering Period, the Board of Directors of Solstice shall, prior to the Effective Time, take such actions as are necessary or appropriate to provide for a New Purchase Date (as defined in the Solstice ESPP) for the Signing Offering Period in accordance with Section 18.2 of the Solstice ESPP. Each holder of an ESPP Option will receive notice of the New Purchase Date, and each ESPP Option shall be automatically exercised on the New Purchase Date, pursuant to the terms of Section 18.2 of the Solstice ESPP. If the Effective Time occurs after the Exercise Date relating to the Signing Offering Period, the Board of Directors of Solstice shall timely suspend the Solstice ESPP as of immediately following the Exercise Date relating to the Signing Offering Period. All shares of Solstice Common Stock due upon exercise of ESPP Options will be issued prior to the Effective Time and no ESPP Options will be outstanding as of the Effective Time.

3.4 Adjustment of Exchange Ratios. If any of the Company, Solstice, Glass, GB and GB II changes the number of shares of capital stock or shares, as applicable, issued and outstanding as a result of a stock split, reverse stock split, stock dividend, recapitalization, reclassification, combination or exchange of shares or other similar transaction, in each case only to the extent permitted by

A-23

Section 6.1 or Section 6.2, and the record date for such an event is on or subsequent to the date of this Agreement but prior to the Effective Time, the Solstice Exchange Ratio, the GB Exchange Ratio, the GB II Exchange Ratio and the number of shares of Company Common Stock issuable pursuant to each of the Mergers, and other items dependent thereon, shall be appropriately adjusted to provide the holders of capital stock of Solstice, GB GB II and Glass Members, as the case may be, the same economic effect as contemplated by this Agreement prior to such event.

3.5 Rule 16b-3 Approval. Prior to the Effective Time, Solstice and the Company, and their respective Boards of Directors or committees thereof, shall take all actions necessary or appropriate to cause any dispositions of Solstice Common Stock (including derivative securities with respect to Solstice Common Stock) or acquisitions of Company Common Stock (including derivative securities with respect to Company Common Stock) resulting from the Transactions by each individual who is or will be subject to the reporting requirements of Section 16(a) of the Exchange Act to be exempt from Section 16(b) of the Exchange Act under Rule 16b-3 promulgated under the Exchange Act in accordance with the terms and conditions set forth in no-action letters issued by the SEC in similar transactions.

3.6 Withholding. Each of the Surviving Entities, Glass, Solstice, the Company, any Subsidiary thereof and the Exchange Agent shall be entitled to deduct and withhold from amounts otherwise payable by it under this Agreement such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign Tax law, and to collect any necessary Tax forms, including Forms W-8 or W-9, as applicable, or any similar information, from holders of Solstice Common Stock, Glass Stockholders, OEP Glass Members and any other recipients of payments hereunder. In the event that any amount is so deducted and withheld, and properly remitted, such amount will be treated for all purposes of this Agreement as having been paid to the Person to whom the payment from which such amount was withheld was made.

3.7 Appraisal Rights.

(a) In accordance with Section 262 of the DGCL, no appraisal rights shall be available to holders of any shares of Solstice Common Stock in connection with the Solstice Merger.

(b) Notwithstanding anything to the contrary contained in this Agreement, Dissenting Shares and Dissenting Cayman Shares shall not be converted into or represent the right to receive any consideration in accordance with Section 3.1(b)(ii), Section 3.1(c)(ii) or Section 3.1(d)(ii) but shall be entitled only to such rights as are granted by the applicable Appraisal Statute to a holder of Dissenting Shares or Dissenting Cayman Shares.

(c) If any Dissenting Shares or Dissenting Cayman Shares shall lose their status as such (through failure to perfect or otherwise), then, as of the later of the Effective Time or the date of loss of such status, such shares shall thereupon be deemed to have been converted as of the Effective Time into the right to receive the consideration otherwise payable in respect thereof pursuant to this Agreement, without interest thereon, upon surrender of the Certificate formerly representing such shares and shall not thereafter be deemed to be Dissenting Shares or Dissenting Cayman Shares, as the case may be.

(d) Each Glass Party shall give Solstice (i) prompt notice of any written demand for appraisal received by any Glass Party pursuant to the applicable Appraisal Statute, any withdrawal of any such demand and any other demand, notice or instrument delivered to any Glass Party prior to the Effective Time pursuant to the applicable Appraisal Statute that relates to such demand and (ii) the opportunity to participate in all negotiations and proceedings with respect to any such demand, notice or instrument. No Glass Party shall settle or make any payment or settlement offer prior to the Effective Time with respect to any such demand, notice or instrument unless Solstice shall have given its written consent to such settlement, payment or settlement offer.

ARTICLE 4
REPRESENTATIONS AND WARRANTIES OF THE SOLSTICE PARTIES

Except (a) as set forth in the applicable section of the disclosure letter delivered by Solstice to Glass on the date of this Agreement (the "Solstice Disclosure Letter") (it being agreed that any information disclosed in a section of the Solstice Disclosure Letter with respect to a corresponding Section of this Agreement shall be deemed to have been disclosed with respect to any other Section of this Agreement to the extent the applicability thereto is reasonably apparent from the face of the disclosure), or (b) other than with respect to Sections 4.1 and 4.3, as disclosed in the Solstice Reports (excluding the exhibits thereto) filed by Solstice with the SEC between December 31, 2014 and the date three (3) Business Days prior to the date hereof (other than in any "risk factor" section of the Solstice Reports, any disclosures in any section of the Solstice Reports designated as relating to forward-looking statements or any other disclosures included therein to the extent they are primarily predictive, cautionary or forward-looking in nature), the Solstice Parties, jointly and severally, hereby represent and warrant to the Glass Parties as follows:

4.1 Existence; Good Standing; Corporate Authority. Each Solstice Party is an entity duly organized, validly existing and in good standing under the laws of the State of Delaware. Each Solstice Party is duly qualified to do business as a foreign entity and is in good standing under the laws of any jurisdiction in which the character of the properties owned or leased by it therein or in which the transaction of its business makes such qualification necessary (to the extent the "good standing" concept is applicable in the case of any jurisdiction outside the United States), except where the failure to be so qualified would not, individually or in the aggregate, reasonably be expected to have a Solstice Material Adverse Effect. Each Solstice Party has all requisite corporate (or comparable) power and authority to own, operate and lease its properties and to carry on its business as now conducted. The copies of the certificates of incorporation and by-laws (or comparable governing documents) of each Solstice Party previously made available to Glass are true and correct and contain all amendments as of the date hereof.

4.2 Authorization, Validity and Effect of Agreements. Each Solstice Party has the requisite corporate (or comparable) power and authority to execute and deliver this Agreement and all other agreements and documents contemplated hereby to which it is or will be a party. The consummation by each Solstice Party of the Transactions has been duly authorized by all requisite corporate (or comparable) action on the part of such Solstice Party, other than (a) in the case of Solstice, (i) the adoption of this Agreement and approval of the Solstice Merger by the holders of a majority of the outstanding shares of Solstice Common Stock entitled to vote thereon at a stockholders' meeting duly called and held for such purpose and (ii) if applicable, the approval by Solstice's stockholders of the issuance of shares of Company Common Stock pursuant to the Transactions and any proposal related to the Solstice Merger that is required pursuant to Rule 14a-4(b) promulgated under the Exchange Act to be presented separately to such stockholders for approval or to be submitted to stockholders of Solstice pursuant to applicable NASDAQ rules in connection with the Transactions (any such proposals, the "Solstice Merger-Related Proposals") by the affirmative vote of a majority of shares present in person or represented by proxy at a meeting duly called and held for such purpose and entitled to vote on such matters shall be the act of the stockholders (clauses (i) and (ii) together, the "Required Solstice Stockholder Approval") and (b) in the case of Solstice Merger Sub, the adoption of this Agreement and the approval of the Solstice Merger by the Company, as Solstice Merger Sub's sole stockholder, which will be obtained by written consent and delivered to Glass immediately after the execution of this Agreement (the "Required Solstice Merger Sub Stockholder Approval"). This Agreement constitutes the valid and legally binding obligation of each Solstice Party, enforceable against such Solstice Party in accordance with its terms, subject to applicable bankruptcy, insolvency, moratorium or other similar laws relating to creditors' rights and general principles of equity.

All issued and outstanding shares of Solstice Common Stock (A) are duly authorized, validly issued, fully paid, nonassessable and free of preemptive rights, (B) were not issued in violation of the terms of any agreement or other understanding binding upon Solstice and (C) were issued in compliance with the certificate of incorporation and by-laws of Solstice and all applicable federal and state securities laws, rules and regulations.

(c) There are no stockholder agreements, voting trusts or other agreements or understandings to which Solstice or any of its Subsidiaries is a party or, to Solstice's knowledge, otherwise with respect to the voting of the capital stock or other equity interests of Solstice or any of its Subsidiaries.

Solstice has made available to Glass a copy of each Solstice Stock Plan and the forms of awards agreement for grants of awards thereunder (and, where not included in such forms, a description of the terms and conditions of vesting (including any acceleration upon an acquisition, change in control or similar transaction) for each outstanding award). All outstanding Solstice Restricted Shares, Solstice Options and Solstice RSUs have been granted pursuant to individual award agreements in the forms of award agreements made available to Glass and/or filed as exhibits with the SEC.

(e) The shares of Company Common Stock issuable pursuant to the Mergers, when issued, sold and delivered in accordance with the terms of this Agreement, will be duly authorized, validly issued, fully paid and nonassessable and, assuming the accuracy of the representations and warranties of the Glass Stockholders and the OEP Glass Members in their respective Letters of

A-26

Transmittal, will be issued in compliance with all applicable federal and state securities laws, rules and regulations.

4.4 Significant Subsidiaries. Each of Solstice's Significant Subsidiaries is a corporation or limited liability company duly organized, validly existing and in good standing (where applicable) under the laws of its jurisdiction of incorporation or organization, has the corporate (or comparable) power and authority to own, operate and lease its properties and to carry on its business as it is now being conducted, and is duly qualified to do business and is in good standing (where applicable) in each jurisdiction in which the ownership, operation or lease of its property or the conduct of its business requires such qualification (to the extent the "good standing" concept is applicable in the case of any jurisdiction outside the United States), except for jurisdictions in which such failure to be so qualified or to be in good standing would not, individually or in the aggregate, reasonably be expected to have a Solstice Material Adverse Effect. All of the outstanding shares of capital stock or other securities of, or other ownership interests in, each of Solstice's Significant Subsidiaries are duly authorized, validly issued, fully paid and nonassessable and are owned, directly or indirectly, by Solstice free and clear of all Liens. There are no existing options, rights of first refusal, conversion rights, preemptive rights, calls, puts, commitments, arrangements or obligations of any character, including voting agreements, proxies or similar arrangements relating to the issued or unissued capital stock or other securities of, or other ownership interests in, any Subsidiary of Solstice. Solstice does not directly or indirectly own any equity or similar interest in, or any interest convertible into or exchangeable or exercisable for any equity or similar interest in, any corporation, partnership, joint venture or other business association or entity that directly or indirectly conducts any activity which is material to Solstice and its Subsidiaries taken as a whole. The copies of Solstice's Subsidiaries' certificates of incorporation, by-laws and similar governing documents previously made available to Glass are true and correct and contain all amendments as of the date hereof. Exhibit 21.1 to Solstice's Annual Report on Form 10-K for the year ended December 31, 2016 filed with the SEC prior to the date hereof sets forth for each Significant Subsidiary of Solstice, its name and jurisdiction of incorporation or organization.

4.5 No Violation. Neither Solstice nor any of its Subsidiaries is, or has received notice or is otherwise aware that it would be with the passage of time, in violation of any term, condition or provision of (a) the certificate of incorporation or by-laws of Solstice, (b) the certificate of incorporation, by-laws or comparable governing documents of any Subsidiary of Solstice, (c) any loan or credit agreement, note, bond, mortgage, indenture, Contract, agreement, joint venture, lease, license, franchise, Solstice Permit or other instrument or (d) any Applicable Law, except, in the case of matters described in clauses (c) or (d), as would not, individually or in the aggregate, reasonably be expected to have a Solstice Material Adverse Effect. Solstice and its Subsidiaries hold all permits, licenses, variances, exemptions, orders, franchises and approvals of all Governmental Authorities necessary for the lawful conduct of their respective businesses (the "Solstice Permits"), except where the failure so to hold would not, individually or in the aggregate, reasonably be expected to have a Solstice Material Adverse Effect. Solstice and its Subsidiaries are in compliance with the terms of the Solstice Permits, except where the failure so to comply would not, individually or in the aggregate, reasonably be expected to have a Solstice Material Adverse Effect. No investigation by any Governmental Authority with respect to Solstice or any of its Subsidiaries is pending or, to the knowledge of Solstice, threatened, other than those the outcome of which would not, individually or in the aggregate, reasonably be expected to have a Solstice Material Adverse Effect.

4.6 No Conflict.

(a) Neither the execution and delivery by any Solstice Party of this Agreement nor the consummation by such Solstice Party of the Transactions in accordance with the terms hereof will: (i) conflict with or result in a breach of any provisions of or create any rights in favor of any other party under the certificate of incorporation or by-laws of Solstice; (ii) conflict with or result in a breach of any provisions of or create any rights in favor of any other party under the certificate of

A-27

Table of Contents

incorporation, by-laws or similar governing documents of any Subsidiary of Solstice; (iii) violate, or conflict with, or result in a breach of any provision of, or constitute a default (or an event which, with notice or lapse of time or both, would constitute a default) under, or result in the termination or in a right of termination or cancellation of, or give rise to a right of purchase under, or accelerate the performance required by, or result in the creation of any Lien upon any of the properties of Solstice or its Subsidiaries under, or result in being declared void, voidable, or without further binding effect, or otherwise result in a detriment to Solstice or any of its Subsidiaries under any of the terms, conditions or provisions of, any loan or credit agreement, note, bond, mortgage, indenture, deed of trust, license, franchise, Solstice Permit, lease, Contract, agreement, joint venture or other instrument or obligation to which Solstice or any of its Subsidiaries is a party, or by which Solstice or any of its Subsidiaries or any of their properties is bound or affected; or (iv) contravene or conflict with or constitute a violation of any provision of any Applicable Laws, except, in the case of matters described in clauses (iii) or (iv), as would not, individually or in the aggregate, reasonably be expected to have a Solstice Material Adverse Effect and except in the case of clause (iv) for the matters described in clauses (i) and (ii) of Section 4.6(b) below.

(b) Neither the execution and delivery by any Solstice Party of this Agreement nor the consummation by such Solstice Party of the Transactions in accordance with the terms hereof will require any consent, approval or authorization of, or filing or registration with, any Governmental Authority, other than (i) the filings provided for in Article 2 and (ii) filings, consents, approvals and authorization required under applicable Antitrust Laws, the Exchange Act, the Securities Act or other applicable U.S. state securities and "blue sky" laws or the rules of NASDAQ ((i) and (ii) collectively, the "Solstice Regulatory Filings"), and listing on NASDAQ of the Company Common Stock to be issued pursuant to the Mergers, or pursuant to stock options or convertible or exchangeable securities of Solstice or Glass, except for any consent, approval or authorization the failure of which to obtain and for any filing or registration the failure of which to make would not prevent or materially delay the consummation of the Mergers or otherwise prevent Solstice from performing its obligations under this Agreement and would not, individually or in the aggregate, reasonably be expected to have a Solstice Material Adverse Effect.

(c) Other than as contemplated by Section 4.6(b) and except for the Required Solstice Stockholder Approval and the Required Solstice Merger Sub Stockholder Approval, no consents, assignments, waivers, authorizations or other certificates are necessary in connection with the Transactions to provide for the continuation in full force and effect of all of the Solstice Material Contracts or for any Solstice Party to consummate the Transactions, except where the failure to receive such consents, assignments, waivers, authorizations or other certificates would not, individually or in the aggregate, reasonably be expected to have a Solstice Material Adverse Effect.

4.7 SEC Documents.

(a) Since December 31, 2014, Solstice has filed all forms, reports and documents with the SEC that have been required to be filed by it under Applicable Laws prior to the date hereof, and Solstice will timely file prior to the Effective Time all forms, reports and documents with the SEC that are required to be filed by it under Applicable Laws prior to such time (all such forms, reports and documents, together with all exhibits and schedules thereto, the "Solstice Reports"). Each of the consolidated balance sheets included in or incorporated by reference into the Solstice Reports (including related notes and schedules) complied as to form in all material respects with the applicable accounting requirements and the published rules and regulations of the SEC with respect thereto and fairly presents in all material respects the consolidated financial position of Solstice and its Subsidiaries (or such entities as indicated in such balance sheet) as of its date, and each of the consolidated statements of operations, cash flows and changes in stockholders' equity included in or incorporated by reference into the Solstice Reports (including any related notes and

A-28

Table of Contents

Each Glass Party is duly qualified to do business as a foreign entity and is in good standing under the laws of any jurisdiction in which the character of the properties owned or leased by it therein or in which the transaction of its business makes such qualification necessary (to the extent the "good standing" concept is applicable in the case of any jurisdiction outside the United States), except where the failure to be so qualified would not, individually or in the aggregate, reasonably be expected to have a Glass Material Adverse Effect. Each Glass Party has all requisite corporate (or comparable) power and authority to own, operate and lease its properties and to carry on its business as now conducted. The copies of the certificate of incorporation or formation, memorandum and articles of association, by-laws, operating agreement and similar formation or governing documents and instruments of each Glass Party (collectively, the "Glass Organizational Documents") previously made available to Solstice are true and correct and contain all amendments as of the date hereof.

5.2 Authorization, Validity and Effect of Agreements. Each Glass Party has the requisite corporate (or comparable) power and authority to execute and deliver this Agreement and all other agreements and documents contemplated hereby to which it is a party. The consummation by each Glass Party of the Transactions has been duly authorized by all requisite corporate (or comparable) action on the part of such Glass Party, other than the adoption of this Agreement and the approval of the applicable Merger by the holders of the requisite majority of the issued and outstanding shares of capital stock of each Glass Party at a meeting duly called and held for such purpose, or the delivery of written consents or proxies in accordance with the Glass Stockholders Agreement and, in the case of Glass, the Companies Law (collectively, the "Required Glass Stockholder Approvals").

All such issued and outstanding equity interests (i) are duly authorized, validly issued, fully paid and non-assessable (as applicable) and free of preemptive rights (other than as set forth in the Glass Stockholders Agreement), (ii) were not issued in violation of the terms of any agreement or other understanding binding upon any Glass Party and (iii) were issued in compliance with the applicable Glass Organizational Documents and all applicable federal and state securities laws, rules and regulations. The Transactions, when consummated in accordance with the terms of this Agreement, will constitute a Realization Event (as defined the Glass Charter).

(b) Except as set forth in the Glass Stockholders Agreement or as described in the list delivered pursuant to Section 5.3(d), there are no outstanding subscriptions, options, warrants, calls, convertible securities or other similar rights, agreements, plans or commitments relating to the issuance of capital stock or other equity interests to which any Glass Party or any of its Subsidiaries is a party obligating any Glass Party or any of its Subsidiaries to (i) issue, transfer or sell any shares of capital stock or other equity interests of any Glass Party or any of its Subsidiaries or securities convertible into or exchangeable for such shares or equity interests, (ii) grant, extend or enter into any such subscription, option, warrant, call, convertible securities or other similar right, agreement or arrangement or (iii) redeem or otherwise acquire any such shares of capital stock or other equity interests (including securities or obligations convertible into or exchangeable or exercisable for any shares of capital stock or other equity interests).

Each such Subsidiary is duly organized, validly existing and in good standing (where applicable) under the laws of its jurisdiction of incorporation or organization, has the corporate (or comparable) power and authority to own, operate and lease its properties and to carry on its business as it is now being conducted, and is duly qualified to do business and is in good standing (where applicable) in each jurisdiction in which the ownership, operation or lease of its property or the conduct of its business requires such qualification (to the extent the "good standing" concept is applicable in the case of any jurisdiction outside the United States), except for jurisdictions in which such failure to be so qualified or to be in good standing would not, individually or in the aggregate, reasonably be expected to have a Glass Material Adverse Effect. All of the outstanding shares of capital stock or other securities of, or other ownership interests in, each such Subsidiary are duly authorized, validly issued, fully paid and nonassessable, and are owned, directly or indirectly, by a Glass Party free and clear of all Liens. There are no existing options, rights of first refusal, conversion rights, preemptive rights, calls, puts, commitments, arrangements or obligations of any character, including voting agreements, proxies or similar arrangements relating to the issued or unissued capital stock or other securities of, or other ownership interests in, any such Subsidiary.

The Glass Parties and their respective Subsidiaries hold all permits, licenses, variances, exemptions, orders, franchises and approvals of all Governmental Authorities necessary for the lawful conduct of their respective businesses (the "Glass Permits"), except where the failure so to hold would not, individually or in the aggregate, reasonably be expected to have a Glass Material Adverse Effect. The Glass Parties and their respective Subsidiaries are in compliance with the terms of the Glass Permits, except where the failure so to comply would not, individually or in the aggregate, reasonably be expected to have a Glass Material Adverse Effect. No investigation by any Governmental Authority with respect to any Glass Party or any of its Subsidiaries is pending or, to the knowledge of Glass, threatened other than those the outcome of which would not, individually or in the aggregate, reasonably be expected to have a Glass Material Adverse Effect.

5.6 No Conflict.

(b) Neither the execution and delivery by any Glass Party of this Agreement nor the consummation by such Glass Party of the Transactions in accordance with the terms hereof will require any consent, approval or authorization of, or filing or registration with, any Governmental Authority, other than (i) the filings provided for in Article 2 and (ii) filings, consents, approvals and authorization required under applicable Antitrust Laws, the Exchange Act, the Securities Act or other applicable U.S. state securities and "blue sky" laws ((i) and (ii) collectively, the "Glass Regulatory Filings"), and listing on NASDAQ of the Company Common Stock to be issued pursuant to the Mergers, or pursuant to stock options or convertible or exchangeable securities of Solstice or any Glass Party, except for any consent, approval or authorization the failure of which to obtain and for any filing or registration the failure of which to make would not prevent or

(c) Other than as contemplated by Section 5.6(b), and except for the Required Glass Stockholder Approvals, no consents, assignments, waivers, authorizations or other certificates are necessary in connection with the Transactions to provide for the continuation in full force and effect of all Glass Material Contracts or for Glass to consummate the Transactions, except where the failure to receive such consents, assignments, waivers, authorizations or other certificates would not, individually or in the aggregate, reasonably be expected to have a Glass Material Adverse Effect.

5.7 Financial Statements.

(a) Section 5.7(a) of the Glass Disclosure Letter sets forth the following financial statements (the "Glass Financial Statements"): (i) the audited consolidated balance sheet of Glass and its Subsidiaries as of December 31, 2016 and as of December 31, 2015, and the related statements of income, changes in equity and cash flows for the years ending December 31, 2016 and December 31, 2015 and (ii) the unaudited consolidated balance sheet of Glass and its Subsidiaries as of March 31, 2017, and the related unaudited statements of operations and cash flows, respectively, for the three-month period ended on such date (the "Glass Most Recent Unaudited Financial Statements"). Each of the Glass Financial Statements has been prepared in accordance with GAAP applied on a basis consistent with prior periods and fairly presents in all material respects the consolidated financial condition of Glass and its Subsidiaries as of its respective date and the consolidated results of operations and stockholders' equity, or cash flows, as the case may be, of Glass and its Subsidiaries for the period covered thereby, subject, in the case of the Glass Most Recent Unaudited Financial Statements, to the absence of footnote disclosure and to normal, recurring end-of-period adjustments which are, in the aggregate, not material.

(b) The financial books and records of the Glass Parties and their respective Subsidiaries have been maintained in accordance with customary business practices and fairly and accurately reflect, in all material respects, on a basis consistent with past periods and throughout the periods involved, (i) the consolidated financial position of the Glass Parties and their respective Subsidiaries and (ii) all transactions of the Glass Parties and their respective Subsidiaries, including all transactions between any Glass Party or any of its Subsidiaries, on the one hand, and any holder of any Glass Party, on the other hand. Glass has not received any advice or notification from its independent accountants that any Glass Party has used any improper accounting practice that would have the effect of not reflecting or incorrectly reflecting in the books and records of any Glass Party or any of its Subsidiaries any properties, assets, liabilities, revenues, expenses, equity accounts or other accounts.

(c) Except as reflected in the Glass Most Recent Unaudited Financial Statements, no Glass Party nor any Subsidiary of any Glass Party has any liabilities of any nature (whether accrued, contingent, absolute or otherwise) that would be required to be reflected on, or reserved against in, a consolidated balance sheet of any Glass Party or in the notes thereto prepared in accordance with GAAP consistently applied, except for liabilities that may have arisen in the ordinary course of business since March 31, 2017 and which are not, and would not reasonably be expected to have, a Glass Material Adverse Effect.

5.8 Litigation. There are no actions, suits or proceedings pending against any Glass Party or any of its Subsidiaries or, to Glass's knowledge, threatened against any Glass Party or any of its Subsidiaries, at law or in equity, or before or by any Governmental Authority, that would reasonably be expected to have, individually or in the aggregate, a Glass Material Adverse Effect. There are no outstanding judgments, decrees, injunctions, awards or orders against any Glass Party or any of its

A-45

Table of Contents

Subsidiaries except as would not, individually or in the aggregate, reasonably be expected to have a Glass Material Adverse Effect.

5.9 Absence of Certain Changes. Since December 31, 2016, each of the Glass Parties and their respective Subsidiaries has conducted its business in the ordinary course consistent with past practice, and there has not been any event that has had or would be reasonably expected to have, individually or in the aggregate, a Glass Material Adverse Effect. Without limiting the generality of the foregoing, since December 31, 2016, no Glass Party nor any of their respective Subsidiaries has taken any action (or has failed to take any action) that would require the consent of Solstice under Section 6.2 if taken (or failed to be taken) after the date of this Agreement and prior to the Effective Time.

5.10 Taxes.

(a) Each of the Glass Parties and their respective Subsidiaries is classified as set forth in Section 5.10(a) of the Glass Disclosure Letter for all U.S. federal and applicable state income Tax purposes.

(b) Each of the Glass Parties and each of their respective Subsidiaries has properly filed on a timely basis all material Tax Returns that it was required to file, and all such Tax Returns are true, correct and complete in all material respects. Except as would not reasonably be expected to have, individually or in the aggregate, a Glass Material Adverse Effect, each of the Glass Parties and each of their respective Subsidiaries has paid on a timely basis all Taxes, whether or not shown on any Tax Return, that were due and payable. Except as would not reasonably be expected to have, individually or in the aggregate, a Glass Material Adverse Effect, the unpaid Taxes of each of the Glass Parties and their respective Subsidiaries (A) for taxable periods through the date of the most recent balance sheet included in the Glass Financial Statements (or, in the case of the Glass Corporate Members, the most recent balance sheet included in the financial books and records of such Glass Corporate Member) do not exceed the accruals and reserves for Taxes (excluding accruals and reserves for deferred Taxes established to reflect timing differences between book and Tax income) set forth on such most recent balance sheet and (B) for taxable periods through the Closing Date, will not exceed the reserve as adjusted for the passage of time through the Closing Date in accordance with GAAP. All material unpaid Taxes of each of the Glass Parties and their respective Subsidiaries for all taxable periods commencing after the date of the most recent balance sheet included in the Glass Financial Statements (or, in the case of the Glass Corporate Members, the most recent balance sheet included in the financial books and records of such Glass Corporate Member) arose in the ordinary course of business.

(c) All material Taxes that the Glass Parties or any of their respective Subsidiaries is or was required by Applicable Law to withhold or collect have been duly withheld or collected and, to the extent required, have been properly paid to the appropriate Governmental Authority, and each of the Glass Parties and each of their respective Subsidiaries has complied with all information reporting and backup withholding requirements in all material respects, including the maintenance of required records with respect thereto, in connection with amounts paid to any employee, independent contractor, creditor, or other third party.

Solstice may extend coverage, effective as of the Effective Time, under Solstice's D&O Insurance by obtaining a six-year "tail" policy prior to the Closing on terms and conditions no less advantageous to the covered persons than Solstice's existing D&O Insurance, and such "tail" policy shall satisfy the provisions of this Section 6.14(a). If such "tail" policy has been obtained by Solstice prior to the Closing, Solstice Surviving Corporation shall maintain such policies in full force and effect and continue to honor Solstice's obligations thereunder. From and after the Effective Time, the Company will guarantee the obligations of Solstice Surviving Corporation under this Section 6.14(a).

(b) The Company shall (A) indemnify, hold harmless and advance expenses to all past and present directors and officers of each Glass Party and its Subsidiaries (in all of their capacities) (x) to the same extent such persons are indemnified or have the right to advancement of expenses as of the date of this Agreement by any Glass Party pursuant to the Glass Organizational Documents and indemnification agreements, if any, in existence on the date hereof with any directors and officers of any Glass Party and its Subsidiaries and (y) without limitation to clause (x), to the fullest extent permitted by Applicable Law, in each case for acts or omissions in their capacities as directors or officers occurring at or prior to the Effective Time (including for acts or omissions occurring in connection with the approval of this Agreement and the consummation of the Transactions), (B) include and cause to be maintained in effect in the applicable Surviving Corporation's (or any successor's) memorandum and articles of association or other organizational documents after the Effective Time provisions regarding elimination of liability of directors, indemnification of officers and directors, and advancement of expenses which are, in the aggregate, no less advantageous to the intended beneficiaries than the corresponding provisions contained in the Glass Organizational Documents, (C) periodically advance to any such indemnitee its legal and other expenses (including the cost of any investigation and preparation incurred in connection therewith), subject to the following clause (c) of this Section 6.14, and subject to the providing by such indemnitee of an undertaking to reimburse all amounts so advanced in the event of a final non-appealable determination by a court of competent jurisdiction that such indemnitee is not entitled thereto and (D) cause to be maintained for a period of six years after the Effective Time the current D&O Insurance maintained by Glass (provided that any Surviving Corporation (or any successor) may substitute therefor one or more policies of at least the same coverage and amounts containing terms and conditions which are, in the aggregate, no less advantageous to the insured) with respect to claims arising from facts or events that occurred on or before the Effective Time; provided, however, that in no event shall the Company or any Surviving Corporation be required pursuant to this Section 6.14(b) to expend in any one year an amount in excess of 300% of the last annual premium paid by Glass for such insurance prior to the date hereof, the amount of such annual premium being set forth in Section 6.14(b) of the Glass Disclosure Letter; provided, further, that if the annual premiums of such insurance coverage exceed such amount, the applicable Surviving Corporation shall be obligated to obtain a policy with the greatest coverage available for a cost not exceeding such amount.

policy prior to the Closing on terms and conditions no less advantageous to the covered persons than Glass's existing D&O Insurance, and such "tail" policy shall satisfy the provisions of this Section 6.14(b). If such "tail" policy has been obtained by Glass prior to the Closing, the applicable Surviving Corporation shall maintain such policies in full force and effect and continue to honor Glass's obligations thereunder. From and after the Effective Time, the Company will guarantee the obligations of the Surviving Entities under this Section 6.14(b).

(c) No Surviving Corporation shall be obligated to pay the fees and expenses of more than one counsel for all indemnitees in any single claim except to the extent that, in the opinion of independent legal counsel selected by the indemnitee, which counsel shall be reasonably acceptable to the Company, representation of two or more of such indemnitees would present a conflict of interest under applicable standards of conduct in the legal profession. No Surviving Corporation shall be liable for any settlement effected without its written consent, which consent shall not unreasonably be withheld.

(d) The obligations of the Company and the Surviving Entities under this Section 6.14 shall not be terminated or modified in such a manner as to adversely affect any indemnitee to whom this Section 6.14 applies without the consent of such affected indemnitee (it being expressly agreed that the indemnitees to whom this Section 6.14 applies shall be third party beneficiaries of this Section 6.14). In the event that the Company, any Surviving Corporation or any of their respective successors or assigns (A) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity in such consolidation or merger or (B) transfers all or substantially all its properties and assets to any person, then and in each case, proper provision shall be made so that the successors and assigns of such person or entity assume the indemnification obligations set forth in this Section 6.14.

(b) None of Solstice, the Glass Parties, the Company, or any of their respective Subsidiaries shall (i) take any action, or fail to take any reasonable action, as a result of which the exchange of Solstice Common Stock for Company Common Stock pursuant to the Solstice Merger would reasonably be expected to fail to qualify either as a reorganization under Section 368(a) of the Code or as a transaction that, taken together with the other Mergers, qualifies as a transfer of property to the Company described in Section 351 of the Code, or (ii) take any action, or fail to take any reasonable action, as a result of which the exchange of Glass Shares for Company Common Stock pursuant to the Cayman Merger, taken together with the other Mergers, would reasonably be expected to fail to qualify as a transaction qualifying as a transfer of property to the Company described in Section 351 of the Code. Each of Solstice and Glass shall use its reasonable best efforts to obtain the opinion of counsel referred to in Sections 7.2(d) and 7.3(d).

(c) The parties shall cooperate to prepare and file any Internal Revenue Service Forms 8937 as required pursuant to Section 6045B of the Code in connection with the Transactions.

Subject to the previous sentence, no provision of this Agreement shall be construed as a limitation on the right of the Company or any Surviving Corporation to amend or terminate any of the foregoing agreements, plans and arrangements to the extent permitted by the terms thereof and Applicable Law, and no provision of this Agreement shall be construed to create a right in any employee, director or beneficiary that such employee, director or beneficiary would not otherwise have under any of the foregoing agreements, plans and arrangements. Section 6.16 shall not apply to persons employed outside the United States or covered by collective bargaining or other labor agreements (such non-U.S. employees and collectively bargained employees, the "Excluded Employees"). The foregoing notwithstanding, the Company agrees to comply with the requirements of Applicable Law with respect to the treatment of Excluded Employees and to honor, or to cause each Surviving Corporation or any of their respective Subsidiaries following the Effective Time to honor, in accordance with their terms all Solstice Plans, Solstice Foreign Plans, Glass Plans, Glass Foreign Plans and all Collective Bargaining Agreements or other labor agreements to which Solstice, Glass, or any of their Subsidiaries is a party or otherwise bound and which apply to the Excluded Employees, provided that such plans or agreements may be amended, terminated or suspended in accordance with their terms and Applicable Law.

(b) The Company shall, and shall cause each Surviving Corporation to, give individuals who were employed by the Company, any Surviving Corporation or their respective Subsidiaries as of the Effective Time (the "Affected Employees") full credit for purposes of eligibility, vesting and determination of the level of benefits (other than benefit accrual under a defined benefit pension plan) under any employee benefit plans or arrangements maintained by the Company, any Surviving Corporation or any of their respective Subsidiaries as of the Effective Time for such Affected Employees' service with Glass or Solstice or any Subsidiary of Glass or Solstice to the same extent recognized by Glass or Solstice immediately prior to the Effective Time; provided, however, that no Affected Employee shall receive a duplication of benefits with respect to the same period of service.

(c) The Company shall use commercially reasonable efforts to, and shall cause each Surviving Corporation to use commercially reasonable efforts to, (i) waive all limitations as to preexisting conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to the Affected Employees under any medical or dental benefit plans that the Affected Employees may be eligible to participate in after the Effective Time, other than limitations or waiting periods that are already in effect with respect to such employees and that have not been satisfied as of the Effective Time under any medical or dental benefit plan maintained for the

A-73

Affected Employees immediately prior to the Effective Time, and (ii) to the extent permitted by the applicable medical or dental plan, provide each Affected Employee with credit for the year in which the Effective Time occurs for any co-payments and deductibles paid prior to the Effective Time in satisfying any applicable deductible or out-of-pocket requirements under any medical and dental plans that the Affected Employees are eligible to participate in after the Effective Time.

The New Equity Plan shall authorize a share reserve for the grant of awards covering a number of shares of Company Common Stock as agreed by Solstice and Glass and Solstice and Glass agree to cause the Company to allocate a portion of such share reserve consisting of a number of shares of Company Common Stock equal to the sum of (i) the aggregate number of shares of Company Common Stock that would be issued at Closing pursuant to the Assumed Company Options if each such option was "net exercised" on the Closing Date using the VWAP on the day immediately prior to the Closing Date (and for the avoidance of doubt, without any shares of Company Common Stock being withheld to pay income, payroll or other Taxes) and (ii) the aggregate number of shares of Company Common Stock covered by equity awards under the Solstice Stock Plans that are assumed by the Company pursuant to Sections 3.3(b) and 3.3(c) for grants to employees of the Glass Surviving Corporation and its Subsidiaries. The New Equity Plan will be in a form agreed to by Solstice and Glass and no awards under the New Equity Plan may be made on or prior to the Effective Time without the consent of Glass. The Company will adopt, and Solstice agrees that, as the stockholder of the Company, it will approve the adoption of, the New Equity Plan prior to the Effective Time.

(e) Prior to the Effective Time, each of Solstice and Glass shall cause the Solstice Plans and Solstice Foreign Plans and the Glass Plans and Glass Foreign Plans to be amended as necessary to the extent permitted by Applicable Law so that (i) no Affected Employee who, immediately prior to the Effective Time, was an employee of Solstice or one of its Subsidiaries shall be eligible to participate in a Glass Plan or Glass Foreign Plan as of the Effective Time and (ii) no Affected Employee who, immediately prior to the Effective Time, was an employee of Glass or one of its Subsidiaries shall be eligible to participate in a Solstice Plan or Solstice Foreign Plan as of the Effective Time.

(f) Glass and Solstice and their respective Subsidiaries have taken or caused to be taken all action necessary such that neither the execution of this Agreement nor the consummation of any of the Transactions shall constitute an event that requires the funding of any rabbi or similar trust with respect to any Solstice Plan, Solstice Foreign Plan, Glass Plan or Glass Foreign Plan.

(g) This Section 6.16 is included for the sole benefit of the parties hereto and their respective transferees and permitted assigns and does not and shall not, except between the parties hereto, create any right in or obligation to any Person, including any Affected Employee, any person previously employed by the parties, any participant in any Solstice Plan, Glass Plan, or successor or replacement plan or arrangement or any beneficiary or trustee thereof. Nothing contained in this Agreement (express or implied) (i) is intended to require the Company or its Affiliates to establish or maintain or cause to be established or maintained any specific employee benefit plan or other compensatory arrangement for any length of time, (ii) is intended to create such a plan or arrangement or amend any of the foregoing, (iii) is intended to confer upon any individual any right to employment or other service relationship or continued employment or service relationship for any period of time, or any right to a particular term or condition of employment or service, or (iv) shall be construed to indicate existence of employment relations between Company and any of its service providers (including contractors and consultants). No Affected Employee or other current or former employee of any of the parties or their Affiliates, including any beneficiary or

dependent thereof, or any other Person not a party to this Agreement, shall be entitled to assert any claim (directly or as a third party beneficiary) against Solstice, Glass, the Company, the Surviving Entities or any of their respective Affiliates under this Section 6.16.

6.17 Notification. Solstice, Glass and each of the Glass Members shall give prompt notice to the other of (i) any representation or warranty made by it or him or contained in this Agreement becoming untrue or inaccurate in any material respect and (ii) the failure by it or him to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement; provided, however, that no such notification shall affect the representations, warranties, covenants or agreements of the parties or the conditions to the obligations of the parties under this Agreement.

6.18 Security Holder Litigation. Each of Solstice and Glass shall provide the other party the opportunity to participate in the defense of any litigation brought by stockholders or any holder of other securities of Solstice or shareholders or any holder of other securities of Glass or any Glass Corporate Member or in the name of Solstice or Glass against Solstice or Glass, as applicable, and/or their respective directors or officers related to this Agreement or any of the Transactions; provided, however, that no party shall compromise, settle, come to an arrangement regarding or agree to compromise, settle or come to an arrangement regarding any litigation arising or related to this Agreement or any of the Transactions, or consent to the same, without the prior written consent of the other party (not to be unreasonably withheld, conditioned of delayed), except that no such consent shall be required for any such settlement, compromise or arrangement that would not result in the payment by such party of any amount in excess of $1,000,000 over and above any retention or deductible under any applicable insurance policy.

6.19 FIRPTA Compliance. On or prior to the Closing Date, (i) each of GB and GB II shall deliver or cause to be delivered to the Company a signed original of a certification that the shares of their respective stock are not United States real property interests as defined in Section 897(c) of the Code, together with a notice to the Internal Revenue Service (which shall be filed by the Company with the Internal Revenue Service following the Closing Date), in accordance with the Treasury Regulations under Sections 897 and 1445 of the Code and (ii) Glass shall deliver to the Company a signed original of a certification pursuant to Treasury Regulation Section 1.1445-11T(d)(2). If any of GB, GB II or Glass has not provided such certification and notice, as applicable, to the Company on or before the Closing Date, the Company shall be permitted to withhold from the payments to be made pursuant to this Agreement any required withholding Tax under Section 1445 of the Code.

6.20 280G Vote. Not less than three (3) Business Days prior to the Closing Date, each of the Glass Parties shall submit to a stockholder vote, in a manner that satisfies the stockholder approval requirements under Section 280G(b)(5)(B) of the Code and the Treasury Regulations promulgated thereunder, the right of any "disqualified individual" (as defined in Section 280G(c) of the Code) of such Glass Party that executed any required waiver or consent to receive all or a portion of payments (or other benefits) contingent on the consummation of the Transactions (within the meaning of Section 280G(b)(2)(A)(i) of the Code) to the extent necessary so that, upon stockholder approval, no payment received by such "disqualified individual" shall be a "parachute payment" under Section 280G(b) of the Code (determined without regard to Section 280G(b)(4) of the Code). Such vote shall establish each such disqualified individual's right to the payment or other compensation that, absent waiver and stockholder approval in accordance with Section 280G of the Code, could constitute a "parachute payment" under Section 280G(b) of the Code, and each of the Glass Parties shall use commercially reasonable efforts to obtain any required waivers or consents from the disqualified individuals of such Glass Party prior to the vote. In addition, each of the Glass Parties shall provide adequate disclosure to their respective stockholders that hold voting capital stock of all material facts concerning all payments to any such disqualified individual that, but for such vote, could be deemed a "parachute payment" under Section 280G of the Code in a manner that satisfies

A-75

Table of Contents

Section 280G(b)(5)(B)(ii) of the Code and Treasury Regulations promulgated thereunder. At least five (5) Business Days prior to the vote, Solstice and its counsel shall be given the right to review and comment on all documents required to be delivered to each of the Glass Parties' respective stockholders in connection with such vote and any required disqualified individual waivers or consents (or a form thereof), and each of the Glass Parties shall reflect all reasonable comments of Solstice thereon to the extent provided within three (3) Business Days following the receipt by Solstice or its counsel of such document, waiver, or consent, as applicable. Prior to soliciting the vote, each of the Glass Parties shall provide to Solstice and its counsel copies of all waivers or consents executed by the disqualified individuals of such Glass Party in connection with the vote, and promptly following the vote, Solstice and its counsel shall be provided copies of all documents executed by each of the Glass Parties' respective stockholders in connection with the vote. For the avoidance of doubt, if, absent any action under this Section 6.20, no payment to any disqualified individual of a Glass Party would constitute a "parachute payment" under Section 280G(b) of the Code, such Glass Party will have no obligations to take any actions pursuant to this Section 6.20.

6.21 Allocation Schedule. Not less than one (1) day prior to the Closing Date, Glass shall deliver to Solstice the Allocation Schedule.

6.22 Glass Indebtedness. Prior to the Closing Date, Glass shall obtain and deliver to Solstice executed payoff letters (the "Payoff Letters"), to be effective upon the Closing, from each lender of Indebtedness of Glass and any of its Subsidiaries as of immediately prior to the Closing (the "Glass Closing Indebtedness"). Subject to the satisfaction or waiver of the conditions set forth in Section 7.1 and Section 7.2, at the Closing and on behalf of the applicable Glass Party, the Company shall pay, in cash by wire transfer of immediately available funds, the Glass Closing Indebtedness in the amounts set forth in the Payoff Letters delivered pursuant to this Section 6.22 and pursuant to wire instructions provided by Glass to Solstice prior to the Closing Date.

6.23 Termination of 401(k) Plan. Prior to the Closing Date, Glass and Solstice will review the advisability of either (a) termination of one or more of the existing Glass Plans or Solstice Plans intended to comply with Section 401(k) of the Code (each a "401(k) Plan") to take effect prior to the Closing Date (a "Plan Termination") or (b) merger of the 401(k) Plans of the Parties as soon as practicable following the Effective Time (a "Plan Merger"). In the event the Parties agree to effect a Plan Termination, the Board of Directors of either Glass or Solstice, as applicable, will adopt resolutions for the foregoing, having first provided the other party with the form of resolutions and obtained its approval not less than two (2) Business Days preceding the Closing Date and the party whose 401(k) Plan is being terminated will provide other Party with evidence that such 401(k) Plan has been terminated pursuant to resolution of the applicable Board of Directors prospectively adopted and effective not later than the day immediately preceding the Closing Date. In the event Glass and Solstice agree to effect a Plan Merger, the Company shall and shall cause the Surviving Corporations to take all steps necessary or appropriate to merge the 401(k) Plans as soon as reasonably practicable after the Effective Time (or such later date agreed between the Parties).

The waiver by any party hereto of a breach of any provision hereunder shall not operate or be construed as a waiver of any prior or subsequent breach of the same or any other provision hereunder.

9.11 Incorporation of Disclosure Letters and Exhibits. The Solstice Disclosure Letter, the Glass Disclosure Letter and all Exhibits and Schedules hereto are hereby incorporated herein and made a part hereof for all purposes as if fully set forth herein.

9.12 Severability. If any provision (or part thereof) of this Agreement is invalid, illegal or unenforceable, that provision (or part thereof) will, to the extent possible, be modified in such a manner as to be valid, legal and enforceable but so as to retain most nearly the intent of the parties as expressed herein, and if such a modification is not possible, that provision (or part thereof) will be severed from this Agreement, and in either case the validity, legality and enforceability of the

A-84

Table of Contents

remaining provisions (or parts thereof) of this Agreement will not in any way be affected or impaired thereby. If any provision (or part thereof) of this Agreement is so broad as to be unenforceable, the provision (or part thereof) shall be interpreted to be only so broad as is enforceable.

9.13 Enforcement of Agreement. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with its specific terms or if this Agreement was otherwise breached and that monetary damages, even if available, would not be an adequate remedy hereunder. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any Delaware Court without proof of actual damages and each party hereto waives any requirement for the securing or posting of any bond in connection with such remedy, this being in addition to any other remedy to which they are entitled at law or in equity. The parties further agree not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to Applicable Law or in equity for any reason, nor to assert that a remedy of monetary damages would provide an adequate remedy for such breach.

1,000 shares of common stock, par value $0.001 per share (the "Common Stock"); and

Table of Contents

B.
  PREFERRED STOCK.

1. General.

Shares of Preferred Stock may be issued from time to time in one or more series, each of such series to have such powers, designations, preferences, and relative, participating, optional, or other special rights, if any, and such qualifications and restrictions, if any, of such preferences and rights, as are stated or expressed in the resolution or resolutions of the Board of Directors providing for such series of Preferred Stock. Different series of Preferred Stock shall not be construed to constitute different classes of shares for the purposes of voting by classes unless expressly so provided in such resolution or resolutions.

Authority is hereby granted to the Board of Directors from time to time to issue the Preferred Stock in one or more series, and in connection with the creation of any such series, by resolution or resolutions to determine and fix the powers, designations, preferences, and relative, participating, optional, or other special rights, if any, and the qualifications and restrictions, if any, of such preferences and rights, including without limitation dividend rights, conversion rights, voting rights (if any), redemption privileges, and liquidation preferences, of such series of Preferred Stock (which need not be uniform among series), all to the fullest extent now or hereafter permitted by the DGCL. Without limiting the generality of the foregoing, the resolution or resolutions providing for the creation or issuance of any series of Preferred Stock may provide that such series shall be superior to, rank equally with, or be junior to the Preferred Stock of any other series, all to the fullest extent permitted by law. No resolution, vote, or consent of the holders of the capital stock of the Corporation shall be required in connection with the creation or issuance of any shares of any series of Preferred Stock authorized by and complying with the conditions of this Restated Certificate of Incorporation, the right to any such resolution, vote, or consent being expressly waived by all present and future holders of the capital stock of the Corporation.

Any resolution or resolutions adopted by the Board of Directors pursuant to the authority vested in them by this Article IV shall be set forth in a certificate of designation along with the number of shares of stock of such series as to which the resolution or resolutions shall apply and such certificate shall be executed, acknowledged, filed, recorded, and shall become effective, in accordance with Section 103 of the DGCL. Unless otherwise provided in any such resolution or resolutions, the number of shares of stock of any such series to which such resolution or resolutions apply may be increased (but not above the total number of authorized shares of the class) or decreased (but not below the number of shares thereof then outstanding) by a certificate likewise executed, acknowledged, filed and recorded, setting forth a statement that a specified increase or decrease therein has been authorized and directed by a resolution or resolutions likewise adopted by the Board of Directors. In case the number of such shares shall be decreased, the number of shares so specified in the certificate shall resume the status which they had prior to the adoption of the first resolution or resolutions. When no shares of any such class or series are outstanding, either because none were issued or because none remain outstanding, a certificate setting forth a resolution or resolutions adopted by the Board of Directors that none of the authorized shares of such class or series are outstanding, and that none will be issued subject to the certificate of designations previously filed with respect to such class or series, may be executed, acknowledged, filed and recorded in the same manner as previously described and it shall have the effect of eliminating from this Restated Certificate of Incorporation all matters set forth in the certificate of designations with respect to such class or series of stock. If no shares of any such class or series established by a resolution or resolutions adopted by the Board of Directors have been issued, the voting powers, designations, preferences and relative, participating, optional or other rights, if any, with the qualifications, limitations or restrictions thereof, may be amended by a resolution or resolutions adopted by the Board of Directors. In the event of any such amendment, a certificate which (i) states that no shares of such class or series have been issued, (ii) sets forth the copy of the amending resolution or resolutions and (iii) if the designation of such class or series is being changed,

A-93

Table of Contents

indicates the original designation and the new designation, shall be executed, acknowledged, filed, recorded, and shall become effective, in accordance with Section 103 of the DGCL.

ARTICLE V
BOARD OF DIRECTORS

The following provisions are inserted for the management of the business and for the conduct of the affairs of the Corporation and for defining and regulating the powers of the Corporation and its directors and stockholders and are in furtherance and not in limitation of the powers conferred upon the Corporation by statute:

(a) Each director shall hold office until the next annual meeting of stockholders and until his or her respective successor shall have been duly elected and qualified, subject, however, to prior death, resignation, retirement, disqualification or removal from office. Except as may otherwise be provided by the DGCL or the By-Laws of the Corporation, any director or the entire Board of Directors may be removed from office at any time, with or without cause but only by the affirmative vote of the holders of at least 66 2/3% of the voting power of the shares of the Corporation's stock entitled to vote for the election of directors. The number of directors constituting the full Board of Directors shall be such number as the Board of Directors from time to time may determine.

(b) The Board of Directors shall have the power and authority: (i) to adopt, amend or repeal By-Laws of the Corporation, subject only to such limitations, if any, as may be from time to time imposed by other provisions of this Certificate, by law, or by the By-Laws; and (ii) to the full extent permitted or not prohibited by law, and without the consent of or other action by the stockholders, to authorize or create mortgage, pledges or other liens or encumbrances upon any or all of the assets, real, personal or mixed, and franchises of the Corporation, including after-acquired property, and to exercise all of the powers of the Corporation in connection therewith.

ARTICLE VI
LIMITATION OF LIABILITY

No director of the Corporation shall be personally liable to the Corporation or to any of its stockholders for monetary damages for breach of fiduciary duty as a director, notwithstanding any provision of law imposing such liability; PROVIDED, HOWEVER, that to the extent required from time to time by applicable law, this Article VI shall not eliminate or limit the liability of a director, to the extent such liability is provided by applicable law, (i) for any breach of the director's duty of loyalty to the Corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of Title 8 of the DGCL, or (iv) for any transactions from which the director derived an improper personal benefit. No amendment to or repeal of this Article VI shall apply to or have any effect on the liability or alleged liability of any director for or with respect to any acts or omissions of such director occurring prior to the effective date of such amendment or repeal.

ARTICLE VII
INDEMNIFICATION

The Corporation shall, to the fullest extent permitted by Section 145 of the DGCL, as amended from time to time, indemnify each person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he is or was, or has agreed to become, a director or officer of the Corporation, or is or was serving, or has agreed to serve, at the request of the Corporation, as a director, officer or trustee of, or in a similar capacity with, another corporation, partnership, joint venture, trust or other enterprise (including any employee benefit plan), or by reason of any action alleged to have been taken or omitted in such capacity, against all expenses (including attorneys' fees),

A-94

Table of Contents

judgements, fines and amounts paid in settlement actually and reasonably incurred by him or on his behalf in connection with such action, suit or proceeding and any appeal therefrom.

Indemnification may include payment by the Corporation of expenses in defending an action or proceeding in advance of the final disposition of such action or proceeding upon receipt of an undertaking by the person indemnified to repay such payment if it is ultimately determined that such person is not entitled to indemnification under this Article VII, which undertaking may be accepted without reference to the financial ability of such person to make such repayment.

The Corporation shall not indemnify any such person seeking indemnification in connection with a proceeding (or part thereof) initiated by such person unless the initiation thereof was approved by the Board of Directors.

The indemnification rights provided in this Article VII (i) shall not be deemed exclusive of any other rights to which those indemnified may be entitled under any law, agreement or vote of stockholders or disinterested directors or otherwise, and (ii) shall inure to the benefit of the heirs, executors and administrators of such persons. The Corporation may, to the extent authorized from time to time by its Board of Directors, grant indemnification rights to other employees or agents of the Corporation or other persons serving the Corporation and such rights may be equivalent to, or greater or less than, those set forth in this Article VII.

ARTICLE VIII
COMPROMISES AND ARRANGEMENTS

Whenever a compromise or arrangement is proposed between the Corporation and its creditors or any class of them and/or between the Corporation and its stockholders or any class of them, any court of equitable jurisdiction within the State of Delaware may, on the application in a summary way of the Corporation or of any creditor or stockholder thereof or on the application of any receiver or receivers appointed for the Corporation under Section 291 of Title 8 of the Delaware Code or on the application of trustees in dissolution or of any receiver or receivers appointed for the Corporation under Section 279 of Title 8 of the Delaware Code order a meeting of the creditors or class of creditors, and/or of the stockholders or class of stockholders of the Corporation, as the case may be, to be summoned in such manner as the said court directs. If a majority in number representing three-fourths (3/4ths) in value of the creditors or class of creditors, and/or of the stockholders or class of stockholders of the Corporation, as the case may be, agree to any compromise or arrangement and to any reorganization of the Corporation as consequence of such compromise or arrangement, the said compromise or arrangement and the said reorganization shall, if sanctioned by the court to which the said application has been made, be binding on all the creditors or class of creditors, and/or on all the stockholders or class of stockholders, of the Corporation, as the case may be, and also on the Corporation.

ARTICLE IX
CERTAIN TRANSACTIONS

The Board of Directors, when considering a tender offer or merger or acquisition proposal, may take into account factors in addition to potential economic benefits to stockholders, including without limitation (i) comparison of the proposed consideration to be received by stockholders in relation to the then current market price of the Corporation's capital stock, the estimated current value of the Corporation in a freely negotiated transaction, and the estimated future value of the Corporation as an independent entity, (ii) the impact of such a transaction on the employees, suppliers, and customers of the Corporation and its effect on the communities in which the Corporation operates, and (iii) the impact of such a transaction on the unique corporate culture and atmosphere of the Corporation.

A-95

ARTICLE X
STOCKHOLDER ACTION

Any action required or permitted to be taken by the stockholders of the Corporation may be taken either at a duly called annual or special meeting of the stockholders or by written consent in lieu of such a meeting, and special meetings of stockholders may be called only by the Chairman of the Board of Directors, the President, or a majority of the Board of Directors.

ARTICLE XI
SEVERABILITY

To the extent that any provision of this Restated Certificate of Incorporation is found to be invalid or unenforceable, such invalidity or unenforceability shall not affect the validity or enforceability of any other provision of this Restated Certificate of Incorporation, and following any determination by a court of competent jurisdiction that any provision of this Restated Certificate of incorporation is invalid or unenforceable, this Restated Certificate of Incorporation shall contain only such provisions (i) as were in effect immediately prior to such determination and (ii) were not so determined to be invalid or unenforceable.

ARTICLE XII
AMENDMENTS

Unless otherwise indicated, capitalized terms not defined herein have the meanings set forth in the Agreement.

A. Representations. The undersigned hereby certifies and represents that the following facts are true, correct and complete in all respects and will be true, correct and complete in all respects at the Effective Time:

1. Solstice and, to the best knowledge of the undersigned, the stockholders of Solstice ("Equityholders") are participating in the Solstice Merger for good and valid business reasons and not for tax purposes. The terms of the Agreement and all other agreements entered into in connection with the Agreement are the products of arm's length negotiation;

3. Each Equityholder will transfer its stock in Solstice pursuant to the Solstice Merger solely in exchange for Company stock (and/or cash received in lieu of fractional shares of Company stock). Any cash received in lieu of fractional shares of Company stock is the only consideration other than Company stock that will be received by Equityholders in connection with the transfer of their stock in Solstice in the Solstice Merger. Any Company stock to be received by the Equityholders will be issued by the Company;

4. Other than with regard to Company Stock issued in exchange for Compensatory Solstice Stock, which Company stock shall not exceed 1.5% of the value of all Company stock that is issued and outstanding after the Mergers, no Company stock or securities will be issued in the Solstice Merger for services rendered to or for the benefit of the Company or its Subsidiaries in connection with the Solstice Merger. "Compensatory Solstice Stock" shall mean any Solstice Restricted Shares and any Solstice stock received in settlement of Solstice RSUs that vest by reason of the Solstice Merger;

5. No Company stock or securities will be issued in the Solstice Merger for indebtedness of the Company or for interest on indebtedness of the Company;

6. There is no intercorporate indebtedness existing between Solstice, on the one hand, and the Company, on the other hand, that was issued, acquired, or will be settled at a discount;

7. The Solstice Merger is not the result of the solicitation by a promoter, broker, or investment house;

8. The Equityholders will not retain any rights in the Solstice stock to be transferred to the Company pursuant to the Solstice Merger at or after the Effective Time;

9. No Company stock received in the Solstice Merger will be received in exchange for any licenses, leases or similar rights between the Equityholders and the Company;

17. To the best knowledge of the undersigned, there is no plan or intention on the part of the Company to redeem or otherwise reacquire any stock or indebtedness to be issued by the Company in the Mergers. To the best knowledge of the undersigned, no person related to the Company, as defined in Treas. Reg. Section 1.368-1(e)(3), and no person acting as intermediary for the Company or such related person (i) has acquired any stock of Solstice or (ii) has a plan or intention to acquire any of the Company stock to be issued in the Mergers;

18. To the best knowledge of the undersigned, the Equityholders do not have any plan or intention to sell, exchange or otherwise dispose of any of the Company stock to be issued in the Solstice Merger;

19. To the best knowledge of the undersigned, taking into account any issuance of additional shares of Company stock, any issuance of Company stock for services (including the Company stock that will be issued to holders of Class E Shares (as defined in the Amended and Restated Memorandum and Articles of Association of Glass) of Glass and the Company stock that will be issued to holders of Compensatory Solstice Stock in respect of such Compensatory Solstice Stock, which Company stock, in the aggregate, shall not exceed 1.5% of the value of all Company stock that is issued and outstanding after the Mergers (such Company common stock issued to such holders, the "Compensatory Company Stock")), the exercise of any Company stock rights, warrants or subscriptions, a public offering of Company stock, and the sale, exchange, transfer by gift, or other disposition of any of the stock of Company to be received in the Mergers, the direct shareholders of Glass immediately prior to the Mergers (excluding for this purpose (i) any shareholders of Glass who receive Compensatory Company Stock and (ii) the Glass Corporate Members and their stockholders), together with the Equityholders (excluding for this purpose any Equityholders who receive Compensatory Company Stock in their capacity as holders of Compensatory Solstice Stock) (together, such holders, the "Control Transferors"), will be in "control" (within the meaning of Sections 351(a) and 368(c) of the Code) of the Company immediately after the Mergers;

exercised, would affect the Control Transferors' acquisition and retention of "control" (within the meaning of Sections 351(a) and 368(c) of the Code) of the Company. To the best knowledge of the undersigned, there is no plan or intention for the Company to issue additional shares of Company stock after the Mergers, or take any other action, that would result in the Control Transferors not being in "control" of the Company after the Mergers;

21. The Equityholders will receive Company stock with a fair market value approximately equal to the fair market value of the Solstice stock disposed of in the Solstice Merger;

22. No Company stock will be placed in escrow or will be issued after the Closing Date pursuant to a contingent stock arrangement, in each case, in connection with the Mergers;

23. The principal purpose of the formation and use of the Company is not the avoidance of U.S. federal income tax or to obtain a U.S. federal income tax benefit that would have otherwise been unavailable;

24. To the best knowledge of the undersigned, the Company will remain in existence and retain and use the property transferred to it in a trade or business (or such property will reflect the ownership of subsidiaries engaged in a trade or business);

25. To the best knowledge of the undersigned, the Company has no plan or intention (i) to liquidate Solstice, (ii) to merge Glass or Solstice with or into another entity, (iii) to sell or otherwise dispose of the shares of Glass or the stock of Solstice acquired in the Mergers, (iv) to sell or otherwise dispose of the assets of Glass or Solstice or (v) to cause Glass or Solstice to sell or otherwise dispose of any of its assets, except, in the case of (iv) and (v), dispositions of assets made in the ordinary course of business and, in the case of (iii), (iv) and (v), transfers or successive transfers of stock or assets to one or more corporations controlled (within the meaning of Section 368(c) of the Code) in each case by the transferor corporation;

26. Each of the parties to the Mergers will pay its own expenses, if any, incurred in connection with the proposed transactions;

5.1
  For the purpose of determining Members entitled to notice of, or to vote at any meeting of Members or any adjournment thereof, or Members entitled to receive payment of any Dividend or other distribution, or in order to make a determination of Members for any other purpose, the Directors may provide that the Register of Members shall be closed for transfers for a stated period which shall not in any case exceed forty days.

If the Directors refuse to register a transfer they shall notify the transferee within two months of such refusal.
7.2
  The instrument of transfer of any Share shall be in writing and shall be executed by or on behalf of the transferor (and if the Directors so require, signed by or on behalf of the transferee).

8
  Redemption, Repurchase and Surrender of Shares
8.1
  Subject to the provisions of the Statute the Company may issue Shares that are to be redeemed or are liable to be redeemed at the option of the Member or the Company.

8.3
  The Company may make a payment in respect of the redemption or purchase of its own Shares in any manner permitted by the Statute, including out of capital.
8.4
  The Directors may accept the surrender for no consideration of any fully paid Share.

9.2
  The Directors may determine to cancel a Treasury Share or transfer a Treasury Share on such terms as they think proper (including, without limitation, for nil consideration).

10 Variation of Rights of Shares

10.1
  If at any time the share capital of the Company is divided into different classes of Shares, all or any of the rights attached to any class (unless otherwise provided by the terms of issue of the Shares of that class) may, whether or not the Company is being wound up, be varied without the consent of the holders of the issued Shares of that class where such variation is considered by the Directors not to have a material adverse effect upon such rights; otherwise, any such variation shall be made only with the consent in writing of the holders of not less than two thirds of the issued Shares of that class, or with the approval of a resolution passed by a majority of not less than two thirds of the votes cast at a separate meeting of the holders of the Shares of that class. For the avoidance of doubt, the Directors reserve the right, notwithstanding

B-10

Table of Contents

that any such variation may not have a material adverse effect, to obtain consent from the holders of Shares of the relevant class. To any such meeting all the provisions of the Articles relating to general meetings shall apply mutatis mutandis, except that the necessary quorum shall be one person holding or representing by proxy at least one third of the issued Shares of the class and that any holder of Shares of the class present in person or by proxy may demand a poll.

10.2
  For the purposes of a separate class meeting, the Directors may treat two or more or all the classes of Shares as forming one class of Shares if the Directors consider that such class of Shares would be affected in the same way by the proposals under consideration, but in any other case shall treat them as separate classes of Shares.
10.3
  The rights conferred upon the holders of the Shares of any class issued with preferred or other rights shall not, unless otherwise expressly provided by the terms of issue of the Shares of that class, be deemed to be varied by the creation or issue of further Shares ranking pari passu therewith.
11
  Commission on Sale of Shares

  The Company may, in so far as the Statute permits, pay a commission to any person in consideration of his subscribing or agreeing to subscribe (whether absolutely or conditionally) or procuring or agreeing to procure subscriptions (whether absolutely or conditionally) for any Shares. Such commissions may be satisfied by the payment of cash and/or the issue of fully or partly paid-up Shares. The Company may also on any issue of Shares pay such brokerage as may be lawful.

12
  Non Recognition of Trusts

  The Company shall not be bound by or compelled to recognise in any way (even when notified) any equitable, contingent, future or partial interest in any Share, or (except only as is otherwise provided by the Articles or the Statute) any other rights in respect of any Share other than an absolute right to the entirety thereof in the holder.

13 Lien on Shares

13.1
  The Company shall have a first and paramount lien on all Shares (whether fully paid-up or not) registered in the name of a Member (whether solely or jointly with others) for all debts, liabilities or engagements to or with the Company (whether presently payable or not) by such Member or his estate, either alone or jointly with any other person, whether a Member or not, but the Directors may at any time declare any Share to be wholly or in part exempt from the provisions of this Article. The registration of a transfer of any such Share shall operate as a waiver of the Company's lien thereon. The Company's lien on a Share shall also extend to any amount payable in respect of that Share.
13.2
  The Company may sell, in such manner as the Directors think fit, any Shares on which the Company has a lien, if a sum in respect of which the lien exists is presently payable, and is not paid within fourteen clear days after notice has been received or deemed to have been received by the holder of the Shares, or to the person entitled to it in consequence of the death or bankruptcy of the holder, demanding payment and stating that if the notice is not complied with the Shares may be sold.
13.3
  To give effect to any such sale the Directors may authorise any person to execute an instrument of transfer of the Shares sold to, or in accordance with the directions of, the purchaser. The purchaser or his nominee shall be registered as the holder of the Shares comprised in any such

B-11

Table of Contents

transfer, and he shall not be bound to see to the application of the purchase money, nor shall his title to the Shares be affected by any irregularity or invalidity in the sale or the exercise of the Company's power of sale under the Articles.

13.4
  The net proceeds of such sale after payment of costs, shall be applied in payment of such part of the amount in respect of which the lien exists as is presently payable and any balance shall (subject to a like lien for sums not presently payable as existed upon the Shares before the sale) be paid to the person entitled to the Shares at the date of the sale.

  Subject to the terms of the allotment and issue of any Shares, the Directors may make calls upon the Members in respect of any monies unpaid on their Shares (whether in respect of par value or premium), and each Member shall (subject to receiving at least fourteen clear days' notice specifying the time or times of payment) pay to the Company at the time or times so specified the amount called on the Shares. A call may be revoked or postponed, in whole or in part, as the Directors may determine. A call may be required to be paid by instalments. A person upon whom a call is made shall remain liable for calls made upon him notwithstanding the subsequent transfer of the Shares in respect of which the call was made.
14.2
  A call shall be deemed to have been made at the time when the resolution of the Directors authorising such call was passed.
14.3
  The joint holders of a Share shall be jointly and severally liable to pay all calls in respect thereof.
14.4
  If a call remains unpaid after it has become due and payable, the person from whom it is due shall pay interest on the amount unpaid from the day it became due and payable until it is paid at such rate as the Directors may determine (and in addition all expenses that have been incurred by the Company by reason of such non-payment), but the Directors may waive payment of the interest or expenses wholly or in part.
14.5
  An amount payable in respect of a Share on issue or allotment or at any fixed date, whether on account of the par value of the Share or premium or otherwise, shall be deemed to be a call and if it is not paid all the provisions of the Articles shall apply as if that amount had become due and payable by virtue of a call.
14.6
  The Directors may issue Shares with different terms as to the amount and times of payment of calls, or the interest to be paid.
14.7
  The Directors may, if they think fit, receive an amount from any Member willing to advance all or any part of the monies uncalled and unpaid upon any Shares held by him, and may (until the amount would otherwise become payable) pay interest at such rate as may be agreed upon between the Directors and the Member paying such amount in advance.
14.8
  No such amount paid in advance of calls shall entitle the Member paying such amount to any portion of a Dividend or other distribution payable in respect of any period prior to the date upon which such amount would, but for such payment, become payable.
15
  Forfeiture of Shares
15.1
  If a call or instalment of a call remains unpaid after it has become due and payable the Directors may give to the person from whom it is due not less than fourteen clear days' notice requiring payment of the amount unpaid together with any interest which may have accrued and any expenses incurred by the Company by reason of such non-payment. The notice shall specify

B-12

Table of Contents

where payment is to be made and shall state that if the notice is not complied with the Shares in respect of which the call was made will be liable to be forfeited.

15.2
  If the notice is not complied with, any Share in respect of which it was given may, before the payment required by the notice has been made, be forfeited by a resolution of the Directors.

  Such forfeiture shall include all Dividends, other distributions or other monies payable in respect of the forfeited Share and not paid before the forfeiture.

15.3
  A forfeited Share may be sold, re-allotted or otherwise disposed of on such terms and in such manner as the Directors think fit and at any time before a sale, re-allotment or disposition the forfeiture may be cancelled on such terms as the Directors think fit. Where for the purposes of its disposal a forfeited Share is to be transferred to any person the Directors may authorise some person to execute an instrument of transfer of the Share in favour of that person.
15.4
  A person any of whose Shares have been forfeited shall cease to be a Member in respect of them and shall surrender to the Company for cancellation the certificate for the Shares forfeited and shall remain liable to pay to the Company all monies which at the date of forfeiture were payable by him to the Company in respect of those Shares together with interest at such rate as the Directors may determine, but his liability shall cease if and when the Company shall have received payment in full of all monies due and payable by him in respect of those Shares.
15.5
  A certificate in writing under the hand of one Director or officer of the Company that a Share has been forfeited on a specified date shall be conclusive evidence of the facts stated in it as against all persons claiming to be entitled to the Share. The certificate shall (subject to the execution of an instrument of transfer) constitute a good title to the Share and the person to whom the Share is sold or otherwise disposed of shall not be bound to see to the application of the purchase money, if any, nor shall his title to the Share be affected by any irregularity or invalidity in the proceedings in reference to the forfeiture, sale or disposal of the Share.
15.6
  The provisions of the Articles as to forfeiture shall apply in the case of non payment of any sum which, by the terms of issue of a Share, becomes payable at a fixed time, whether on account of the par value of the Share or by way of premium as if it had been payable by virtue of a call duly made and notified.
16
  Transmission of Shares
16.1
  If a Member dies the survivor or survivors (where he was a joint holder) or his legal personal representatives (where he was a sole holder), shall be the only persons recognised by the Company as having any title to his Shares. The estate of a deceased Member is not thereby released from any liability in respect of any Share, for which he was a joint or sole holder.
16.2
  Any person becoming entitled to a Share in consequence of the death or bankruptcy or liquidation or dissolution of a Member (or in any other way than by transfer) may, upon such evidence being produced as may be required by the Directors, elect, by a notice in writing sent by him to the Company, either to become the holder of such Share or to have some person nominated by him registered as the holder of such Share. If he elects to have another person registered as the holder of such Share he shall sign an instrument of transfer of that Share to that person. The Directors shall, in either case, have the same right to decline or suspend registration as they would have had in the case of a transfer of the Share by the relevant Member before his death or bankruptcy or liquidation or dissolution, as the case may be.
16.3
  A person becoming entitled to a Share by reason of the death or bankruptcy or liquidation or dissolution of a Member (or in any other case than by transfer) shall be entitled to the same Dividends, other distributions and other advantages to which he would be entitled if he were the

B-13

Table of Contents

holder of such Share. However, he shall not, before becoming a Member in respect of a Share, be entitled in respect of it to exercise any right conferred by membership in relation to general meetings of the Company and the Directors may at any time give notice requiring any such person to elect either to be registered himself or to have some person nominated by him be registered as the holder of the Share (but the Directors shall, in either case, have the same right to decline or suspend registration as they would have had in the case of a transfer of the Share by the relevant Member before his death or bankruptcy or liquidation or dissolution or any other case than by transfer, as the case may be). If the notice is not complied with within ninety days of being received or deemed to be received (as determined pursuant to the Articles) the Directors may thereafter withhold payment of all Dividends, other distributions, bonuses or other monies payable in respect of the Share until the requirements of the notice have been complied with.

17
  Amendments of Memorandum and Articles of Association and Alteration of Capital

  The Company may by Ordinary Resolution:
  (a)

    consolidate and divide all or any of its share capital into Shares of larger amount than its existing Shares;
  (c)
    convert all or any of its paid-up Shares into stock, and reconvert that stock into paid-up Shares of any denomination;

  (e)
    cancel any Shares that at the date of the passing of the Ordinary Resolution have not been taken or agreed to be taken by any person and diminish the amount of its share capital by the amount of the Shares so cancelled.
17.2
  All new Shares created in accordance with the provisions of the preceding Article shall be subject to the same provisions of the Articles with reference to the payment of calls, liens, transfer, transmission, forfeiture and otherwise as the Shares in the original share capital.

  General Meetings
19.1
  All general meetings other than annual general meetings shall be called extraordinary general meetings.
19.2
  The Company may, but shall not (unless required by the Statute) be obliged to, in each year hold a general meeting as its annual general meeting, and shall specify the meeting as such in the notices calling it. Any annual general meeting shall be held at such time and place as the Directors shall appoint and if no other time and place is prescribed by them, it shall be held at the Registered Office on the second Wednesday in December of each year at ten o'clock in the morning. At these meetings the report of the Directors (if any) shall be presented.
19.3
  The Directors may call general meetings, and they shall on a Members' requisition forthwith proceed to convene an extraordinary general meeting of the Company.
19.4
  A Members' requisition is a requisition of Members holding at the date of deposit of the requisition not less than ten per cent. in par value of the issued Shares which as at that date carry the right to vote at general meetings of the Company.
19.5
  The Members' requisition must state the objects of the meeting and must be signed by the requisitionists and deposited at the Registered Office, and may consist of several documents in like form each signed by one or more requisitionists.
19.6
  If there are no Directors as at the date of the deposit of the Members' requisition or if the Directors do not within twenty-one days from the date of the deposit of the Members' requisition duly proceed to convene a general meeting to be held within a further twenty-one days, the requisitionists, or any of them representing more than one-half of the total voting rights of all of the requisitionists, may themselves convene a general meeting, but any meeting so convened shall be held no later than the day which falls three months after the expiration of the said twenty-one day period.
19.7
  A general meeting convened as aforesaid by requisitionists shall be convened in the same manner as nearly as possible as that in which general meetings are to be convened by Directors.
20
  Notice of General Meetings
20.1
  At least five clear days' notice shall be given of any general meeting. Every notice shall specify the place, the day and the hour of the meeting and the general nature of the business to be conducted at the general meeting and shall be given in the manner hereinafter mentioned or in such other manner if any as may be prescribed by the Company, provided that a general meeting of the Company shall, whether or not the notice specified in this Article has been given and whether or not the provisions of the Articles regarding general meetings have been complied with, be deemed to have been duly convened if it is so agreed:
  (a)
    in the case of an annual general meeting, by all of the Members entitled to attend and vote thereat; and
  (b)
    in the case of an extraordinary general meeting, by a majority in number of the Members having a right to attend and vote at the meeting, together holding not less than ninety five per cent. in par value of the Shares giving that right.
20.2
  The accidental omission to give notice of a general meeting to, or the non receipt of notice of a general meeting by, any person entitled to receive such notice shall not invalidate the proceedings of that general meeting.

21 Proceedings at General Meetings

21.1
  No business shall be transacted at any general meeting unless a quorum is present. Two Members being individuals present in person or by proxy or if a corporation or other non-natural person by its duly authorised representative or proxy shall be a quorum unless the Company has only one Member entitled to vote at such general meeting in which case the quorum shall be that one Member present in person or by proxy or (in the case of a corporation or other non-natural person) by its duly authorised representative or proxy.
21.2
  A person may participate at a general meeting by conference telephone or other communications equipment by means of which all the persons participating in the meeting can communicate with each other. Participation by a person in a general meeting in this manner is treated as presence in person at that meeting.
21.3
  A resolution (including a Special Resolution) in writing (in one or more counterparts) signed by or on behalf of all of the Members for the time being entitled to receive notice of and to attend and vote at general meetings (or, being corporations or other non-natural persons, signed by their duly authorised representatives) shall be as valid and effective as if the resolution had been passed at a general meeting of the Company duly convened and held.
21.4
  If a quorum is not present within half an hour from the time appointed for the meeting to commence or if during such a meeting a quorum ceases to be present, the meeting, if convened upon a Members' requisition, shall be dissolved and in any other case it shall stand adjourned to the same day in the next week at the same time and/or place or to such other day, time and/or place as the Directors may determine, and if at the adjourned meeting a quorum is not present within half an hour from the time appointed for the meeting to commence, the Members present shall be a quorum.
21.5
  The Directors may, at any time prior to the time appointed for the meeting to commence, appoint any person to act as chairman of a general meeting of the Company or, if the Directors do not make any such appointment, the chairman, if any, of the board of Directors shall preside as chairman at such general meeting. If there is no such chairman, or if he shall not be present within fifteen minutes after the time appointed for the meeting to commence, or is unwilling to act, the Directors present shall elect one of their number to be chairman of the meeting.
21.6
  If no Director is willing to act as chairman or if no Director is present within fifteen minutes after the time appointed for the meeting to commence, the Members present shall choose one of their number to be chairman of the meeting.
21.7
  The chairman may, with the consent of a meeting at which a quorum is present (and shall if so directed by the meeting) adjourn the meeting from time to time and from place to place, but no business shall be transacted at any adjourned meeting other than the business left unfinished at the meeting from which the adjournment took place.
21.8
  When a general meeting is adjourned for thirty days or more, notice of the adjourned meeting shall be given as in the case of an original meeting. Otherwise it shall not be necessary to give any such notice of an adjourned meeting.
21.9
  A resolution put to the vote of the meeting shall be decided on a show of hands unless before, or on the declaration of the result of, the show of hands, the chairman demands a poll, or any other Member or Members collectively present in person or by proxy (or in the case of a corporation or other non-natural person, by its duly authorised representative or proxy) and holding at least ten per cent. in par value of the Shares giving a right to attend and vote at the meeting demand a poll.

B-16

Table of Contents

21.10
  Unless a poll is duly demanded and the demand is not withdrawn a declaration by the chairman that a resolution has been carried or carried unanimously, or by a particular majority, or lost or not carried by a particular majority, an entry to that effect in the minutes of the proceedings of the meeting shall be conclusive evidence of that fact without proof of the number or proportion of the votes recorded in favour of or against such resolution.
21.11
  The demand for a poll may be withdrawn.
21.12
  Except on a poll demanded on the election of a chairman or on a question of adjournment, a poll shall be taken as the chairman directs, and the result of the poll shall be deemed to be the resolution of the general meeting at which the poll was demanded.
21.13
  A poll demanded on the election of a chairman or on a question of adjournment shall be taken forthwith. A poll demanded on any other question shall be taken at such date, time and place as the chairman of the general meeting directs, and any business other than that upon which a poll has been demanded or is contingent thereon may proceed pending the taking of the poll.
21.14
  In the case of an equality of votes, whether on a show of hands or on a poll, the chairman shall be entitled to a second or casting vote.
22
  Votes of Members
22.1
  Subject to any rights or restrictions attached to any Shares, on a show of hands every Member who (being an individual) is present in person or by proxy or, if a corporation or other non-natural person is present by its duly authorised representative or by proxy, shall have one vote and on a poll every Member present in any such manner shall have one vote for every Share of which he is the holder.
22.2
  In the case of joint holders the vote of the senior holder who tenders a vote, whether in person or by proxy (or, in the case of a corporation or other non-natural person, by its duly authorised representative or proxy), shall be accepted to the exclusion of the votes of the other joint holders, and seniority shall be determined by the order in which the names of the holders stand in the Register of Members.
22.3
  A Member of unsound mind, or in respect of whom an order has been made by any court, having jurisdiction in lunacy, may vote, whether on a show of hands or on a poll, by his committee, receiver, curator bonis, or other person on such Member's behalf appointed by that court, and any such committee, receiver, curator bonis or other person may vote by proxy.
22.4
  No person shall be entitled to vote at any general meeting unless he is registered as a Member on the record date for such meeting nor unless all calls or other monies then payable by him in respect of Shares have been paid.
22.5
  No objection shall be raised as to the qualification of any voter except at the general meeting or adjourned general meeting at which the vote objected to is given or tendered and every vote not disallowed at the meeting shall be valid. Any objection made in due time in accordance with this Article shall be referred to the chairman whose decision shall be final and conclusive.
22.6
  On a poll or on a show of hands votes may be cast either personally or by proxy (or in the case of a corporation or other non-natural person by its duly authorised representative or proxy). A Member may appoint more than one proxy or the same proxy under one or more instruments to attend and vote at a meeting. Where a Member appoints more than one proxy the instrument of proxy shall state which proxy is entitled to vote on a show of hands and shall specify the number of Shares in respect of which each proxy is entitled to exercise the related votes.

B-17

Table of Contents

22.7
  On a poll, a Member holding more than one Share need not cast the votes in respect of his Shares in the same way on any resolution and therefore may vote a Share or some or all such Shares either for or against a resolution and/or abstain from voting a Share or some or all of the Shares and, subject to the terms of the instrument appointing him, a proxy appointed under one or more instruments may vote a Share or some or all of the Shares in respect of which he is appointed either for or against a resolution and/or abstain from voting a Share or some or all of the Shares in respect of which he is appointed.
23
  Proxies
23.1
  The instrument appointing a proxy shall be in writing and shall be executed under the hand of the appointor or of his attorney duly authorised in writing, or, if the appointor is a corporation or other non natural person, under the hand of its duly authorised representative. A proxy need not be a Member.
23.2
  The Directors may, in the notice convening any meeting or adjourned meeting, or in an instrument of proxy sent out by the Company, specify the manner by which the instrument appointing a proxy shall be deposited and the place and the time (being not later than the time appointed for the commencement of the meeting or adjourned meeting to which the proxy relates) at which the instrument appointing a proxy shall be deposited. In the absence of any such direction from the Directors in the notice convening any meeting or adjourned meeting or in an instrument of proxy sent out by the Company, the instrument appointing a proxy shall be deposited physically at the Registered Office not less than 48 hours before the time appointed for the meeting or adjourned meeting to commence at which the person named in the instrument proposes to vote.
23.3
  The chairman may in any event at his discretion declare that an instrument of proxy shall be deemed to have been duly deposited. An instrument of proxy that is not deposited in the manner permitted, or which has not been declared to have been duly deposited by the chairman, shall be invalid.
23.4
  The instrument appointing a proxy may be in any usual or common form (or such other form as the Directors may approve) and may be expressed to be for a particular meeting or any adjournment thereof or generally until revoked. An instrument appointing a proxy shall be deemed to include the power to demand or join or concur in demanding a poll.
23.5
  Votes given in accordance with the terms of an instrument of proxy shall be valid notwithstanding the previous death or insanity of the principal or revocation of the proxy or of the authority under which the proxy was executed, or the transfer of the Share in respect of which the proxy is given unless notice in writing of such death, insanity, revocation or transfer was received by the Company at the Registered Office before the commencement of the general meeting, or adjourned meeting at which it is sought to use the proxy.
24
  Corporate Members

  Any corporation or other non-natural person which is a Member may in accordance with its constitutional documents, or in the absence of such provision by resolution of its directors or other governing body, authorise such person as it thinks fit to act as its representative at any meeting of the Company or of any class of Members, and the person so authorised shall be entitled to exercise the same powers on behalf of the corporation which he represents as the corporation could exercise if it were an individual Member.

  Subject to the provisions of the Statute, the Memorandum and the Articles and to any directions given by Special Resolution, the business of the Company shall be managed by the Directors who may exercise all the powers of the Company. No alteration of the Memorandum or Articles and no such direction shall invalidate any prior act of the Directors which would have been valid if that alteration had not been made or that direction had not been given. A duly convened meeting of Directors at which a quorum is present may exercise all powers exercisable by the Directors.
27.2
  All cheques, promissory notes, drafts, bills of exchange and other negotiable or transferable instruments and all receipts for monies paid to the Company shall be signed, drawn, accepted, endorsed or otherwise executed as the case may be in such manner as the Directors shall determine by resolution.

  The Company may by Ordinary Resolution appoint any person to be a Director or may by Ordinary Resolution remove any Director.
28.2

29
  Vacation of Office of Director

  The office of a Director shall be vacated if:

  (a)
    the Director gives notice in writing to the Company that he resigns the office of Director; or
  (b)
    the Director absents himself (for the avoidance of doubt, without being represented by proxy or an alternate Director appointed by him) from three consecutive meetings of the board of

  the Director dies, becomes bankrupt or makes any arrangement or composition with his creditors generally; or
(d)
  the Director is found to be or becomes of unsound mind; or

30
  Proceedings of Directors
30.1
  The quorum for the transaction of the business of the Directors may be fixed by the Directors, and unless so fixed shall be two if there are two or more Directors, and shall be one if there is only one Director. A person who holds office as an alternate Director shall, if his appointor is not present, be counted in the quorum. A Director who also acts as an alternate Director shall, if his appointor is not present, count twice towards the quorum.
30.2
  Subject to the provisions of the Articles, the Directors may regulate their proceedings as they think fit. Questions arising at any meeting shall be decided by a majority of votes. In the case of an equality of votes, the chairman shall have a second or casting vote. A Director who is also an alternate Director shall be entitled in the absence of his appointor to a separate vote on behalf of his appointor in addition to his own vote.
30.3
  A person may participate in a meeting of the Directors or any committee of Directors by conference telephone or other communications equipment by means of which all the persons participating in the meeting can communicate with each other at the same time. Participation by a person in a meeting in this manner is treated as presence in person at that meeting. Unless otherwise determined by the Directors the meeting shall be deemed to be held at the place where the chairman is located at the start of the meeting.
30.4
  A resolution in writing (in one or more counterparts) signed by all the Directors or all the members of a committee of the Directors or, in the case of a resolution in writing relating to the removal of any Director or the vacation of office by any Director, all of the Directors other than the Director who is the subject of such resolution (an alternate Director being entitled to sign such a resolution on behalf of his appointor and if such alternate Director is also a Director, being entitled to sign such resolution both on behalf of his appointer and in his capacity as a Director) shall be as valid and effectual as if it had been passed at a meeting of the Directors, or committee of Directors as the case may be, duly convened and held.
30.5
  A Director or alternate Director may, or other officer of the Company on the direction of a Director or alternate Director shall, call a meeting of the Directors by at least two days' notice in writing to every Director and alternate Director which notice shall set forth the general nature of the business to be considered unless notice is waived by all the Directors (or their alternates) either at, before or after the meeting is held. To any such notice of a meeting of the Directors all the provisions of the Articles relating to the giving of notices by the Company to the Members shall apply mutatis mutandis.
30.6
  The continuing Directors (or a sole continuing Director, as the case may be) may act notwithstanding any vacancy in their body, but if and so long as their number is reduced below the number fixed by or pursuant to the Articles as the necessary quorum of Directors the continuing Directors or Director may act for the purpose of increasing the number of Directors

B-20

Table of Contents

to be equal to such fixed number, or of summoning a general meeting of the Company, but for no other purpose.

30.7
  The Directors may elect a chairman of their board and determine the period for which he is to hold office; but if no such chairman is elected, or if at any meeting the chairman is not present within five minutes after the time appointed for the meeting to commence, the Directors present may choose one of their number to be chairman of the meeting.
30.8
  All acts done by any meeting of the Directors or of a committee of the Directors (including any person acting as an alternate Director) shall, notwithstanding that it is afterwards discovered that there was some defect in the appointment of any Director or alternate Director, and/or that they or any of them were disqualified, and/or had vacated their office and/or were not entitled to vote, be as valid as if every such person had been duly appointed and/or not disqualified to be a Director or alternate Director and/or had not vacated their office and/or had been entitled to vote, as the case may be.
30.9
  A Director but not an alternate Director may be represented at any meetings of the board of Directors by a proxy appointed in writing by him. The proxy shall count towards the quorum and the vote of the proxy shall for all purposes be deemed to be that of the appointing Director.
31
  Presumption of Assent

  A Director or alternate Director who is present at a meeting of the board of Directors at which action on any Company matter is taken shall be presumed to have assented to the action taken unless his dissent shall be entered in the minutes of the meeting or unless he shall file his written dissent from such action with the person acting as the chairman or secretary of the meeting before the adjournment thereof or shall forward such dissent by registered post to such person immediately after the adjournment of the meeting. Such right to dissent shall not apply to a Director or alternate Director who voted in favour of such action.

32
  Directors' Interests
32.1
  A Director or alternate Director may hold any other office or place of profit under the Company (other than the office of Auditor) in conjunction with his office of Director for such period and on such terms as to remuneration and otherwise as the Directors may determine.
32.2
  A Director or alternate Director may act by himself or by, through or on behalf of his firm in a professional capacity for the Company and he or his firm shall be entitled to remuneration for professional services as if he were not a Director or alternate Director.
32.3
  A Director or alternate Director may be or become a director or other officer of or otherwise interested in any company promoted by the Company or in which the Company may be interested as a shareholder, a contracting party or otherwise, and no such Director or alternate Director shall be accountable to the Company for any remuneration or other benefits received by him as a director or officer of, or from his interest in, such other company.
32.4
  No person shall be disqualified from the office of Director or alternate Director or prevented by such office from contracting with the Company, either as vendor, purchaser or otherwise, nor shall any such contract or any contract or transaction entered into by or on behalf of the Company in which any Director or alternate Director shall be in any way interested be or be liable to be avoided, nor shall any Director or alternate Director so contracting or being so interested be liable to account to the Company for any profit realised by or arising in connection with any such contract or transaction by reason of such Director or alternate Director holding office or of the fiduciary relationship thereby established. A Director (or his alternate Director in his absence) shall be at liberty to vote in respect of any contract or transaction in which he is interested provided that the nature of the interest of any Director or alternate Director in any such contract or transaction shall be disclosed by him at or prior to its consideration and any vote thereon.

B-21

Table of Contents

32.5
  A general notice that a Director or alternate Director is a shareholder, director, officer or employee of any specified firm or company and is to be regarded as interested in any transaction with such firm or company shall be sufficient disclosure for the purposes of voting on a resolution in respect of a contract or transaction in which he has an interest, and after such general notice it shall not be necessary to give special notice relating to any particular transaction.
33
  Minutes

  The Directors shall cause minutes to be made in books kept for the purpose of recording all appointments of officers made by the Directors, all proceedings at meetings of the Company or the holders of any class of Shares and of the Directors, and of committees of the Directors, including the names of the Directors or alternate Directors present at each meeting.

  The Directors may delegate any of their powers, authorities and discretions, including the power to sub-delegate, to any committee consisting of one or more Directors. They may also delegate to any managing director or any Director holding any other executive office such of their powers, authorities and discretions as they consider desirable to be exercised by him provided that an alternate Director may not act as managing director and the appointment of a managing director shall be revoked forthwith if he ceases to be a Director. Any such delegation may be made subject to any conditions the Directors may impose and either collaterally with or to the exclusion of their own powers and any such delegation may be revoked or altered by the Directors. Subject to any such conditions, the proceedings of a committee of Directors shall be governed by the Articles regulating the proceedings of Directors, so far as they are capable of applying.
34.2
  The Directors may establish any committees, local boards or agencies or appoint any person to be a manager or agent for managing the affairs of the Company and may appoint any person to be a member of such committees, local boards or agencies. Any such appointment may be made subject to any conditions the Directors may impose, and either collaterally with or to the exclusion of their own powers and any such appointment may be revoked or altered by the Directors. Subject to any such conditions, the proceedings of any such committee, local board or agency shall be governed by the Articles regulating the proceedings of Directors, so far as they are capable of applying.

34.4
  The Directors may by power of attorney or otherwise appoint any company, firm, person or body of persons, whether nominated directly or indirectly by the Directors, to be the attorney or authorised signatory of the Company for such purpose and with such powers, authorities and discretions (not exceeding those vested in or exercisable by the Directors under the Articles) and for such period and subject to such conditions as they may think fit, and any such powers of attorney or other appointment may contain such provisions for the protection and convenience of persons dealing with any such attorneys or authorised signatories as the Directors may think fit and may also authorise any such attorney or authorised signatory to delegate all or any of the powers, authorities and discretions vested in him.

and removal as the Directors may think fit. Unless otherwise specified in the terms of his appointment an officer of the Company may be removed by resolution of the Directors or Members.

36
  No Minimum Shareholding

  The Company in general meeting may fix a minimum shareholding required to be held by a Director, but unless and until such a shareholding qualification is fixed a Director is not required to hold Shares.

37
  Remuneration of Directors
37.1
  The remuneration to be paid to the Directors, if any, shall be such remuneration as the Directors shall determine. The Directors shall also be entitled to be paid all travelling, hotel and other expenses properly incurred by them in connection with their attendance at meetings of Directors or committees of Directors, or general meetings of the Company, or separate meetings of the holders of any class of Shares or debentures of the Company, or otherwise in connection with the business of the Company or the discharge of their duties as a Director, or to receive a fixed allowance in respect thereof as may be determined by the Directors, or a combination partly of one such method and partly the other.
37.2
  The Directors may by resolution approve additional remuneration to any Director for any services which in the opinion of the Directors go beyond his ordinary routine work as a Director.

38.2
  The Company may have for use in any place or places outside the Cayman Islands a duplicate Seal or Seals each of which shall be a facsimile of the common Seal of the Company and, if the Directors so determine, with the addition on its face of the name of every place where it is to be used.
38.3
  A Director or officer, representative or attorney of the Company may without further authority of the Directors affix the Seal over his signature alone to any document of the Company required to be authenticated by him under seal or to be filed with the Registrar of Companies in the Cayman Islands or elsewhere wheresoever.
39
  Dividends, Distributions and Reserve
39.1
  Subject to the Statute and this Article and except as otherwise provided by the rights attached to any Shares, the Directors may resolve to pay Dividends and other distributions on Shares in issue and authorise payment of the Dividends or other distributions out of the funds of the Company lawfully available therefor. A Dividend shall be deemed to be an interim Dividend unless the terms of the resolution pursuant to which the Directors resolve to pay such Dividend specifically state that such Dividend shall be a final Dividend. No Dividend or other distribution shall be paid except out of the realised or unrealised profits of the Company, out of the share premium account or as otherwise permitted by law.
39.2
  Except as otherwise provided by the rights attached to any Shares, all Dividends and other distributions shall be paid according to the par value of the Shares that a Member holds. If any Share is issued on terms providing that it shall rank for Dividend as from a particular date, that Share shall rank for Dividend accordingly.
39.3
  The Directors may deduct from any Dividend or other distribution payable to any Member all sums of money (if any) then payable by him to the Company on account of calls or otherwise.
39.4
  The Directors may resolve that any Dividend or other distribution be paid wholly or partly by the distribution of specific assets and in particular (but without limitation) by the distribution of shares, debentures, or securities of any other company or in any one or more of such ways and where any difficulty arises in regard to such distribution, the Directors may settle the same as they think expedient and in particular may issue fractional Shares and may fix the value for distribution of such specific assets or any part thereof and may determine that cash payments shall be made to any Members upon the basis of the value so fixed in order to adjust the rights of all Members and may vest any such specific assets in trustees in such manner as may seem expedient to the Directors.
39.5
  Except as otherwise provided by the rights attached to any Shares, Dividends and other distributions may be paid in any currency. The Directors may determine the basis of conversion for any currency conversions that may be required and how any costs involved are to be met.
39.6
  The Directors may, before resolving to pay any Dividend or other distribution, set aside such sums as they think proper as a reserve or reserves which shall, at the discretion of the Directors, be applicable for any purpose of the Company and pending such application may, at the discretion of the Directors, be employed in the business of the Company.
39.7
  Any Dividend, other distribution, interest or other monies payable in cash in respect of Shares may be paid by wire transfer to the holder or by cheque or warrant sent through the post directed to the registered address of the holder or, in the case of joint holders, to the registered

B-24

Table of Contents

address of the holder who is first named on the Register of Members or to such person and to such address as such holder or joint holders may in writing direct. Every such cheque or warrant shall be made payable to the order of the person to whom it is sent. Any one of two or more joint holders may give effectual receipts for any Dividends, other distributions, bonuses, or other monies payable in respect of the Share held by them as joint holders.

39.8
  No Dividend or other distribution shall bear interest against the Company.
39.9
  Any Dividend or other distribution which cannot be paid to a Member and/or which remains unclaimed after six months from the date on which such Dividend or other distribution becomes payable may, in the discretion of the Directors, be paid into a separate account in the Company's name, provided that the Company shall not be constituted as a trustee in respect of that account and the Dividend or other distribution shall remain as a debt due to the Member. Any Dividend or other distribution which remains unclaimed after a period of six years from the date on which such Dividend or other distribution becomes payable shall be forfeited and shall revert to the Company.
40
  Capitalisation

  The Directors may at any time capitalise any sum standing to the credit of any of the Company's reserve accounts or funds (including the share premium account and capital redemption reserve fund) or any sum standing to the credit of the profit and loss account or otherwise available for distribution; appropriate such sum to Members in the proportions in which such sum would have been divisible amongst such Members had the same been a distribution of profits by way of Dividend or other distribution; and apply such sum on their behalf in paying up in full unissued Shares for allotment and distribution credited as fully paid-up to and amongst them in the proportion aforesaid. In such event the Directors shall do all acts and things required to give effect to such capitalisation, with full power given to the Directors to make such provisions as they think fit in the case of Shares becoming distributable in fractions (including provisions whereby the benefit of fractional entitlements accrue to the Company rather than to the Members concerned). The Directors may authorise any person to enter on behalf of all of the Members interested into an agreement with the Company providing for such capitalisation and matters incidental or relating thereto and any agreement made under such authority shall be effective and binding on all such Members and the Company.

41
  Books of Account
41.1
  The Directors shall cause proper books of account (including, where applicable, material underlying documentation including contracts and invoices) to be kept with respect to all sums of money received and expended by the Company and the matters in respect of which the receipt or expenditure takes place, all sales and purchases of goods by the Company and the assets and liabilities of the Company. Such books of account must be retained for a minimum period of five years from the date on which they are prepared. Proper books shall not be deemed to be kept if there are not kept such books of account as are necessary to give a true and fair view of the state of the Company's affairs and to explain its transactions.
41.2
  The Directors shall determine whether and to what extent and at what times and places and under what conditions or regulations the accounts and books of the Company or any of them shall be open to the inspection of Members not being Directors and no Member (not being a Director) shall have any right of inspecting any account or book or document of the Company except as conferred by Statute or authorised by the Directors or by the Company in general meeting.

B-25

42
  Audit
42.1
  The Directors may appoint an Auditor of the Company who shall hold office on such terms as the Directors determine.
42.2
  Every Auditor of the Company shall have a right of access at all times to the books and accounts and vouchers of the Company and shall be entitled to require from the Directors and officers of the Company such information and explanation as may be necessary for the performance of the duties of the Auditor.
42.3
  Auditors shall, if so required by the Directors, make a report on the accounts of the Company during their tenure of office at the next annual general meeting following their appointment in the case of a company which is registered with the Registrar of Companies as an ordinary company, and at the next extraordinary general meeting following their appointment in the case of a company which is registered with the Registrar of Companies as an exempted company, and at any other time during their term of office, upon request of the Directors or any general meeting of the Members.
43
  Notices
43.1
  Notices shall be in writing and may be given by the Company to any Member either personally or by sending it by courier, post, cable, telex, fax or e-mail to him or to his address as shown in the Register of Members (or where the notice is given by e-mail by sending it to the e-mail address provided by such Member). Any notice, if posted from one country to another, is to be sent by airmail.
43.2
  Where a notice is sent by courier, service of the notice shall be deemed to be effected by delivery of the notice to a courier company, and shall be deemed to have been received on the third day (not including Saturdays or Sundays or public holidays) following the day on which the notice was delivered to the courier. Where a notice is sent by post, service of the notice shall be deemed to be effected by properly addressing, pre paying and posting a letter containing the notice, and shall be deemed to have been received on the fifth day (not including Saturdays or Sundays or public holidays in the Cayman Islands) following the day on which the notice was posted. Where a notice is sent by cable, telex or fax, service of the notice shall be deemed to be effected by properly addressing and sending such notice and shall be deemed to have been received on the same day that it was transmitted. Where a notice is given by e-mail service shall be deemed to be effected by transmitting the e-mail to the e-mail address provided by the intended recipient and shall be deemed to have been received on the same day that it was sent, and it shall not be necessary for the receipt of the e-mail to be acknowledged by the recipient.
43.3
  A notice may be given by the Company to the person or persons which the Company has been advised are entitled to a Share or Shares in consequence of the death or bankruptcy of a Member in the same manner as other notices which are required to be given under the Articles and shall be addressed to them by name, or by the title of representatives of the deceased, or trustee of the bankrupt, or by any like description at the address supplied for that purpose by the persons claiming to be so entitled, or at the option of the Company by giving the notice in any manner in which the same might have been given if the death or bankruptcy had not occurred.

B-26

Table of Contents

43.4
  Notice of every general meeting shall be given in any manner authorised by the Articles to every holder of Shares carrying an entitlement to receive such notice on the record date for such meeting except that in the case of joint holders the notice shall be sufficient if given to the joint holder first named in the Register of Members and every person upon whom the ownership of a Share devolves by reason of his being a legal personal representative or a trustee in bankruptcy of a Member where the Member but for his death or bankruptcy would be entitled to receive notice of the meeting, and no other person shall be entitled to receive notices of general meetings.
44
  Winding Up
44.1
  If the Company shall be wound up the liquidator shall apply the assets of the Company in satisfaction of creditors' claims in such manner and order as such liquidator thinks fit. Subject to the rights attaching to any Shares, in a winding up:
  (a)
    if the assets available for distribution amongst the Members shall be insufficient to repay the whole of the Company's issued share capital, such assets shall be distributed so that, as nearly as may be, the losses shall be borne by the Members in proportion to the par value of the Shares held by them; or
  (b)
    if the assets available for distribution amongst the Members shall be more than sufficient to repay the whole of the Company's issued share capital at the commencement of the winding up, the surplus shall be distributed amongst the Members in proportion to the par value of the Shares held by them at the commencement of the winding up subject to a deduction from those Shares in respect of which there are monies due, of all monies payable to the Company for unpaid calls or otherwise.
44.2
  If the Company shall be wound up the liquidator may, subject to the rights attaching to any Shares and with the approval of a Special Resolution of the Company and any other approval required by the Statute, divide amongst the Members in kind the whole or any part of the assets of the Company (whether such assets shall consist of property of the same kind or not) and may for that purpose value any assets and determine how the division shall be carried out as between the Members or different classes of Members. The liquidator may, with the like approval, vest the whole or any part of such assets in trustees upon such trusts for the benefit of the Members as the liquidator, with the like approval, shall think fit, but so that no Member shall be compelled to accept any asset upon which there is a liability.
45
  Indemnity and Insurance
45.1
  Every Director and officer of the Company (which for the avoidance of doubt, shall not include auditors of the Company), together with every former Director and former officer of the Company (each an "Indemnified Person") shall be indemnified out of the assets of the Company against any liability, action, proceeding, claim, demand, costs, damages or expenses, including legal expenses, whatsoever which they or any of them may incur as a result of any act or failure to act in carrying out their functions other than such liability (if any) that they may incur by reason of their own actual fraud or wilful default. No Indemnified Person shall be liable to the Company for any loss or damage incurred by the Company as a result (whether direct or indirect) of the carrying out of their functions unless that liability arises through the actual fraud or wilful default of such Indemnified Person. No person shall be found to have committed actual fraud or wilful default under this Article unless or until a court of competent jurisdiction shall have made a finding to that effect.
45.2
  The Company shall advance to each Indemnified Person reasonable attorneys' fees and other costs and expenses incurred in connection with the defence of any action, suit, proceeding or

B-27

Table of Contents

investigation involving such Indemnified Person for which indemnity will or could be sought. In connection with any advance of any expenses hereunder, the Indemnified Person shall execute an undertaking to repay the advanced amount to the Company if it shall be determined by final judgment or other final adjudication that such Indemnified Person was not entitled to indemnification pursuant to this Article. If it shall be determined by a final judgment or other final adjudication that such Indemnified Person was not entitled to indemnification with respect to such judgment, costs or expenses, then such party shall not be indemnified with respect to such judgment, costs or expenses and any advancement shall be returned to the Company (without interest) by the Indemnified Person.

45.3
  The Directors, on behalf of the Company, may purchase and maintain insurance for the benefit of any Director or other officer of the Company against any liability which, by virtue of any rule of law, would otherwise attach to such person in respect of any negligence, default, breach of duty or breach of trust of which such person may be guilty in relation to the Company.
46
  Financial Year

  Unless the Directors otherwise prescribe, the financial year of the Company shall end on 31st December in each year and, following the year of incorporation, shall begin on 1st January in each year.

47
  Transfer by Way of Continuation

  If the Company is exempted as defined in the Statute, it shall, subject to the provisions of the Statute and with the approval of a Special Resolution, have the power to register by way of continuation as a body corporate under the laws of any jurisdiction outside the Cayman Islands and to be deregistered in the Cayman Islands.

48
  Mergers and Consolidations

  The Company shall have the power to merge or consolidate with one or more other constituent companies (as defined in the Statute) upon such terms as the Directors may determine and (to the extent required by the Statute) with the approval of a Special Resolution.

Annex C

Article 5.2 and Related Provisions of
the Amended and Restated Memorandum and Articles of Association
(the "Articles of Association")
of GENBAND Holdings Company

Set forth below is the text of Article 5.2 and other related provisions of the Articles of Association. GENBAND will send a copy of the full text of the Articles of Association to GENBAND shareholders, GB stockholders and GB II stockholders, without charge, upon such shareholders' request.

5.2
  Subject to the Statute and these Articles, the Board of Directors may resolve to pay Dividends and make other distributions of any assets of the Company or any net proceeds thereof (including, without limitation, any net proceeds resulting from the operation of such assets, the net proceeds of any debt financing transaction using such assets as collateral (to the extent allocable thereto) or the net proceeds of any disposition of such assets, in each case, as such net proceeds are reasonably determined by the Board of Directors), from time to time (as determined by the Board of Directors), subject to such withholding or reserves as the Board of Directors may deem appropriate in its discretion. All such Dividends and distributions, as well as any other distributions (including upon a merger or consolidation of the Company resulting in a change of control involving a third party, a sale of all or substantially all of the assets of the Company and any winding-up, dissolution or liquidation of the Company, in each case, the existence of which shall be determined by the Board of Directors), shall be made in the following order of priority (provided, that the distributions contemplated by Step A and Step B shall occur simultaneously, after giving effect to all Benchmark Amounts):
  (a)
    Step A:
    (i)
      First, to the holders of Class C Shares in proportion to the respective aggregate Class C Accreted Amount of the Class C Shares held thereby based upon which of the following methodologies would result in greater cumulative Dividends and other distributions to the holders of a majority of the Class C Shares:
      (A)
        to the holders of Class C Shares until the cumulative Dividends and other distributions pursuant to this Article 5.2(a)(i) and Article 5.4 equals the aggregate Class C Accreted Amount for all outstanding Class C Shares at the applicable time of the Dividend or distribution;
      (B)
        to the holders of Class C Shares until the cumulative Dividends and other distributions pursuant to this Article 5.2(a)(i) and Article 5.4 equals the aggregate Class C Accreted Amount for all outstanding Class C Shares at the applicable time of the Dividend or distribution; to the holders of Class C Shares until the cumulative Dividends and other distributions pursuant to this Article 5.2(a)(i) and Article 5.4 equals the amount that would be paid in Dividends and other distributions to the holders of Class C Shares pursuant to this Article 5.2 and Article 5.4 if (x) each outstanding Class C Share was converted into that number of Class A Shares equal to the Class C Accreted Amount of such Class C Share at the applicable time of the Dividend or other distribution divided by $0.070486161, (y) each such Class A Share resulting from the hypothetical conversion of Class C Shares pursuant to the proceeding clause (x) had an amount of Unreturned Capital equal to the average amount of the Unreturned Capital of each outstanding Class A Share (not including any Class A Shares resulting from the hypothetical conversion) at the applicable time and (z) all such Dividends and other distributions were made pursuant to Article 5.2

C-1

Table of Contents

and Article 5.4, including the Class A Shares resulting from such hypothetical conversion of Class C Shares into Class A Shares;

(ii)
  second, to the holders of Class A Shares in proportion to the respective Unreturned Capital of each such Member in respect of the Class A Shares held thereby until the cumulative Dividends and other distributions pursuant to this Article 5.2(a)(ii) and Article 5.4 equals the aggregate amount of all Capital Contributions made by holders of Class A Shares with respect to their Class A Shares; and
(iii)
  thereafter, to the holders of Class A Shares and Class B Shares pro rata based on the number of such Shares held by each holder relative to all of the issued and outstanding Class A Shares and Class B Shares; provided, that (x) any Dividends and other distributions to be made in respect of Offset B Shares shall be reduced by any Dividends and other distributions made in respect of Class E Shares that upon their issuance caused the applicable Class B Shares to become Offset B Shares and (y) to the extent any Class E Shares have been redeemed or repurchased by the Company, those Class E Shares nonetheless shall be deemed to be outstanding for purposes of reducing Dividends and distributions in respect of any Offset B Shares pursuant to the immediately preceding clause; and

(b)
  Step B: (i) to the holders of Class E Shares an amount for each Class E Share owned by such holder equal to (x) the total Dividends and other distributions made in respect of Class A Shares, Class B Shares and Class C Shares pursuant to Step A (without giving effect to the reductions thereto pursuant to this Step B), less (y) the Benchmark Amount applicable to the Class E Shares, and that difference multiplied by (z) a fraction, the numerator of which is one (1) and the denominator of which is the total number of the outstanding Class A Shares, Class B Shares, Class C Shares and Class E Shares, and (ii) the total amounts available for Dividends and other distributions to the holders of Class A Shares, Class B Shares and Class C Shares pursuant to Step A will be reduced by the corresponding amounts (as if such amounts were not available for Dividends and other distributions) necessary to make the Dividends and other distributions required pursuant to this Step B.

  Notwithstanding anything to the contrary in this Article 5.2, no Dividend or distribution (other than any tax distribution pursuant to Article 5.4) shall be made in respect of any Class B Share with a Benchmark Amount until the aggregate distributions made to holders of Class A Shares and Class C Shares pursuant to this Article 5.2 and Article 5.4 from the date of issuance of such Class B Share equals the Benchmark Amount of such Class B Share. The amount of any reduction in distributions in respect of a Class B Share resulting from the application of the foregoing sentence shall be distributed in respect of the other outstanding Shares in accordance with this Article 5.2.

(c)
  To further clarify the above, Exhibit A, sets forth an example of hypothetical distributions as of the date and based upon the assumptions set forth in such Exhibit.

4.1(b)
  The Board of Directors shall determine a benchmark amount (the "Benchmark Amount"), if any, with respect to each Class B Share and Class E Share. For the Class B Shares, the Benchmark Amount shall be the sum of (i) the "Benchmark Target" as determined by the Board of Directors at the time such Class B Share is issued which amount shall be reflected in the records of the Company plus (ii) the sum of all Capital Contributions made after the date of such issuance of such Class B Share, less (iii) the sum of all distributions made with respect to the Class A and the Class C Shares after the date of such issuance of such Class B Share under Article 5 hereof For the Class E Shares, the Benchmark Amount shall be the sum of (i) the "Benchmark Target" as determined by the Board of Directors at the time such Class E Share is

C-2

Table of Contents

issued which amount shall be reflected in the records of the Company plus (ii) each time a Capital Contribution is made after the date issuance of such Class E Share, an amount equal to the quotient of (A) the amount of such Capital Contribution divided by (B) the quotient of (x) the total equity value of the Company implied by such Capital Contribution (which shall be determined immediately prior to such Capital Contribution by the Board of Directors in good faith), divided by (y) the Benchmark Amount applicable to such Class E Share immediately prior to such Capital Contribution, less (iii) the sum of all distributions made with respect to the Class A and the Class C Shares after the date of such issuance of such Class E Share under Article 5 hereof. The Class B Shares issued on December 20, 2010 shall have a Benchmark Target equal to zero and the Class E Shares issued on July 30, 2013 shall have a Benchmark Target equal to $478,000,000, It is intended that if a Class B Share or Class E Share issued after that date would, absent a Benchmark Amount, be entitled to a share of proceeds if the Company's assets were sold at their fair market value immediately after issuance of such Class B Share or Class E Share, as applicable, and the proceeds from such sale were distributed in a complete liquidation of the Company, that the Benchmark Target with respect to such newly issued Class B Share or Class E Share, as applicable, be equal to the fair market value (as determined by the Board of Directors in good faith) of the Company's assets on the date of issuance of such Class B Share or Class E Share, as applicable. This Article 4.1(b), together with the provisions of Article 5, is intended to result in each Class B Share and each Class E Share being treated as a "profits interest" for U.S. federal income tax purposes as of the date such Class B Share or such Class E Share, as applicable, is issued. Any person who receives Class B Shares or Class E Shares shall (i), unless such person has already made a Capital Contribution to the Company in exchange for Class A Shares, make a Capital Contribution to the Company in the amount of $1,000 in exchange for Class A Shares, and (ii) make a timely and effective election under Section 83(b) of the Code with respect to such Class B Shares or Class E Shares, as applicable.

4.2
  Combination and Reclassification of Prior Series. On December 19, 2012, (i) each of the Company's Class A Shares (par value $0.00001 per share) previously designated as "GENBAND US Series" and each of the Company's Class A Shares (par value $0.00001 per share) previously designated as "Cayman IP Co Series" were reclassified and redesignated into one share of the Company's Class A Shares (par value $0.00001 per share) and any designation of such Shares as shares of the Prior Series was terminated and extinguished, and (ii) each of the Company's Class B Shares (par value $0.00001 per share) previously designated as "GENBAND US Series" and each of the Company's Class B Shares (par value $0.00001 per share) previously designated as "Cayman IP Co Series" were reclassified and redesignated into one share of the Company's Class B Shares (par value $0.00001 per share) and any designation of such Shares as shares of the Prior Series was terminated and extinguished. The Register of Members was modified and updated to give effect to the reclassification and redesignation of all Class A Shares and Class B Shares of a Prior Series. Any prior allocation or segregation of assets and/or liabilities of the Company by or in respect of a Prior Series was terminated and extinguished as of the close of business on December 19, 2012. Any allocation or segregation of assets and/or liabilities of the Company by or in respect of a Prior Series shall remain in full force and effect for all purposes for any periods prior to and including December 19, 2012. Any reference in the Shareholders Agreement to Shares of either the "GENBAND US Series" or the "Cayman IP Co Series" shall be deemed to refer to a Class A Share or Class B Shares (as applicable) without any designation of such Share as part of any Prior Series.
4.4
  Capital Contributions. The initial capital contributions to the Company made in respect of the Prior Series pursuant to the GENBAND Subscription Agreement, the Contribution Agreement and the Amended and Restated Stock Purchase Agreement shall be deemed to be Capital Contributions to the Company in respect of the Class A Shares into which such shares of the

C-3

Table of Contents

Prior Series were reclassified and redesignated (as described in Article 4.2). With respect to the issuance of all Class A Shares issued through the date of adoption of these Articles (as reclassified and redesignated), the Board of Directors has determined that the value of Capital Contributions made at the time of issuance of each such Class A Share was equal to $0.146. The parties agree that the amount of the Capital Contribution made by OEP III pursuant to the 2012 Contribution Agreement is equal to $343,472,237. The Company and the Members hereby agree that the fair market value of the indebtedness contributed by OEP III pursuant to the 2012 Contribution Agreement is equal to the "liquidation value" (as defined in Section 1.108-8 of the Treasury Regulations) of OEP III's Class C Shares received in exchange therefor and that the "liquidation value" of such Class C Shares is equal to $343,472,237. In the event that any Person makes additional Capital Contributions (other than those described above), such Capital Contributions will be made on terms satisfactory to the Board of Directors and in accordance with the Shareholders Agreement, and additional Shares of the applicable Class, as determined by the Board of Directors, shall be issued to such Person.

The Board of Directors of
Sonus Networks, Inc.
4 Technology Park Drive
Westford, MA 01186

Members of the Board of Directors:

We understand that Sonus Networks, Inc., a Delaware corporation (the "Company"), proposes to enter into an Agreement and Plan of Merger, to be dated as of May 23, 2017 (the "Merger Agreement"), with Solstice Sapphire Investments, Inc., a Delaware corporation and a direct wholly owned subsidiary of the Company ("Newco"), Solstice Sapphire, Inc., a Delaware corporation and a direct wholly owned subsidiary of Newco ("Solstice Merger Sub"), Green Sapphire Investments LLC, a Delaware limited liability company and a direct wholly owned subsidiary of Newco ("Cayman Merger Sub"), Green Sapphire LLC, a Delaware limited liability company and a direct wholly owned subsidiary of Newco ("GB Merger Sub"), Genband Holdings Company, a Cayman Islands exempted company limited by shares ("Glass"), GENBAND Inc., a Delaware corporation ("GB") and GENBAND II, Inc., a Delaware corporation ("GB II" and together with Glass and GB, the "Glass Parties"), pursuant to which (a) Solstice Merger Sub will merge with and into the Company, with the Company surviving as a direct wholly owned subsidiary of Newco (the "Solstice Merger" and, together with the Glass Mergers (as defined below), the "Mergers"), (b) Cayman Merger Sub will merge with and into Glass, with Glass surviving as a direct or indirect wholly owned subsidiary of the Company (the "Glass Merger"), (c) GB will merge with and into GB Merger Sub, with GB Merger Sub surviving as a direct wholly owned subsidiary of Newco (the "GB Merger") and (d) GB II will merge with and into GB Merger Sub, with GB Merger Sub surviving as a direct wholly owned subsidiary of Newco (the "GB II Merger" and, together with the Glass Merger and the GB Merger, the "Glass Mergers").

As a result of (a) the Solstice Merger, each share of common stock, par value $0.001 per share, of the Company (the "Company Common Stock") issued and outstanding immediately prior to the Effective Time (as defined in the Merger Agreement), other than the Excluded Solstice Shares (as defined in the Merger Agreement) will be converted into the right to receive one share of common stock, par value $0.01 per share ("Newco Common Stock"), of Newco (the "Solstice Exchange Ratio"), and (b) the Glass Mergers, among other things, (i) each share of common stock, par value $0.001 per share, of GB issued and outstanding immediately prior to the Effective Time, other than the Excluded GB Shares and Dissenting Shares (each as defined in the Merger Agreement), will be converted into the right to receive a number of shares of Newco Common Stock equal to one multiplied by the GB Exchange Ratio (as defined in the Merger Agreement), (c) each share of common stock, par value $0.001 per share, of GB II issued and outstanding immediately prior to the Effective Time, other than the Excluded GB II Shares and Dissenting Shares (each as defined in the Merger Agreement), will be converted into the right to receive a number of shares of Newco Common Stock equal to one multiplied by the GB II Exchange Ratio (as defined in the Merger Agreement), and (d) each share of capital stock or other equity interest of Glass (the "Glass Shares") issued and outstanding immediately prior to the Effective Time, other than the Excluded Glass Shares and Held Glass Shares (each as defined in the Merger Agreement), will be converted into the right to receive (i) that number of shares of Newco Common Stock and (ii) that portion of the Promissory Note (as defined in the Merger Agreement) that the holder of such Glass Share is entitled to receive as set forth in the Merger Agreement (such portion of the Promissory Note, the "Glass Note Consideration"). The Solstice Exchange Ratio, after giving effect to the Glass Mergers, results in the holders of shares of Company Common Stock immediately prior to the Effective Time holding 50% of the outstanding shares of Newco Common Stock immediately after the Effective Time. The aggregate amount of Newco Common Stock and Glass Note Consideration to be issued in connection with the Glass Mergers is

herein referred to as the "Total Consideration". The terms and conditions of the Mergers are more fully set forth in the Merger Agreement and terms used herein and not defined shall have the meanings ascribed thereto in the Merger Agreement.

The Board of Directors has asked us whether, in our opinion, the Solstice Exchange Ratio is fair, from a financial point of view, to the holders of shares of the Company Common Stock and whether the Total Consideration, taking into account a significant portion of such Total Consideration is in the form of Newco Common Stock, is fair, from a financial point of view, to the Company.

In connection with rendering our opinion, we have, among other things:

(i)
  reviewed certain publicly available information that we deemed to be relevant, including business and financial information (including research analysts' estimates) relating to the Company and business information relating to the Glass Parties;
(ii)
  reviewed certain non-public historical financial statements and other non-public historical financial and operating data relating to the Company and the Glass Parties prepared and furnished to, or otherwise discussed with, us by their respective managements;
(iii)
  reviewed certain non-public projected financial data relating to the Company and the Glass Parties prepared and furnished to, or otherwise discussed with, us by their respective managements;
(iv)
  reviewed certain non-public historical and projected operating data relating to the Company and the Glass Parties prepared and furnished to us by their respective managements;
(v)
  discussed the past and current operations, financial projections and current financial condition of (a) the Company with management of the Company and (b) the Glass Parties with management of the Company and the Glass Parties (including in each case their views on the risks and uncertainties of achieving such projections);
(vi)
  reviewed and discussed with the respective management of the Company and the Glass Parties certain estimates of the present value of the net operating losses of the Company and the Glass Parties prepared and furnished to, or otherwise discussed with, us by their respective managements, to be used after giving effect to the Mergers in accordance with pro forma utilization estimates prepared by or at the direction of and approved by the Company's management;
(vii)
  reviewed analyses performed by respective managements of the Company and the Glass Parties with respect to cost synergies, including the amount and timing thereof, that management believes are realizable by the combined company as a result of the Mergers (the "Synergies");
(viii)
  reviewed the reported prices and the historical trading activity of the Company Common Stock;
(ix)
  compared certain financial performance metrics of the Company and its stock market trading multiples with the financial performance metrics and stock market trading multiples of certain other publicly traded companies that we deemed relevant;
(x)
  compared the financial performance of the Glass Parties and the valuation multiples relating to the Mergers with those of certain other transactions that we deemed relevant;
(xi)
  reviewed a draft of the Merger Agreement, the Principal Stockholders Agreement, the Voting Agreement and the Registration Rights Agreement, each in substantially final form, and assumed that the final form of each such agreement will not vary in any respect material to our analysis; and

(xii)
  performed such other analyses and examinations and considered such other factors that we deemed appropriate.

For purposes of our analysis and opinion, we have assumed and relied upon, without undertaking any independent verification of, the accuracy and completeness of all of the information publicly available, and all of the information supplied or otherwise made available to, discussed with, or reviewed by us, and we assume no liability therefor. With respect to the projected financial data relating to the Company and the Glass Parties referred to above (including the Synergies), we have assumed that they have been reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the managements of the Company and the Glass Parties as to the future financial performance of the Company and the Glass Parties and as to the Synergies, including the amounts and timing of the realization of such Synergies. We express no view as to any projected financial data relating to the Company, the Glass Parties, the Synergies or the assumptions on which they are based, and we have assumed that the financial results reflected in the projected financial data and estimates utilized in our analyses, including with respect to the Synergies, will be realized in the amounts and at the times projected.

For purposes of rendering our opinion, we have assumed, in all respects material to our analysis, that the representations and warranties of each party contained in the Merger Agreement are true and correct, that each party will perform all of the covenants and agreements required to be performed by it under the Merger Agreement and that all conditions to the consummation of the Mergers will be satisfied without material waiver or modification thereof. We have further assumed that all governmental, regulatory or other consents, approvals or releases necessary for the consummation of the Mergers will be obtained without any material delay, limitation, restriction or condition that would have an adverse effect on the Company or the Glass parties or the consummation of the Mergers or materially reduce the benefits to the holders of the Company Common Stock of the Mergers.

We have not made nor assumed any responsibility for making any physical inspection, independent valuation or appraisal of the assets or liabilities of the Company or the Glass Parties, nor have we been furnished with any such inspection, valuation or appraisals, nor have we evaluated the solvency or fair value of the Company or the Glass Parties under any state or federal laws relating to bankruptcy, insolvency or similar matters. Our opinion is necessarily based upon information made available to us as of the date hereof and financial, economic, market and other conditions as they exist and as can be evaluated on the date hereof. It is understood that subsequent developments may affect this opinion and that we do not have any obligation to update, revise or reaffirm this opinion.

We have not been asked to pass upon, and express no opinion with respect to, any matter other than the fairness to the holders of the Company Common Stock, from a financial point of view, of the Solstice Exchange Ratio or the fairness to the Company of the Total Consideration, taking into account a significant portion of such Total Consideration is in the form of Newco Common Stock. We do not express any view on, and our opinion does not address, the fairness of the proposed transaction to, or any consideration received in connection therewith by, the holders of any other securities, creditors or other constituencies of the Company or the Glass Parties, nor as to the fairness of the amount or nature of any compensation to be paid or payable to any of the officers, directors or employees of the Company or any other party to the Merger Agreement, or any class of such persons, whether relative to the Total Consideration or otherwise. We have assumed that any modification to the structure of the transaction will not vary in any respect material to our analysis. Our opinion does not address the relative merits of the Mergers as compared to other business or financial strategies that might be available to the Company, nor does it address the underlying business decision of the Company to engage in the Mergers. In arriving at our opinion, we were not authorized to solicit, and did not solicit, interest from any third party with respect to the acquisition of any or all of the Company Common Stock or any business combination or other extraordinary transaction involving the Company. This letter, and our opinion, does not constitute a recommendation to the Board of Directors or to any

other persons in respect of the Mergers, including as to how any holder of shares of Company Common Stock should vote or act in respect of the Mergers. We express no opinion herein as to the price at which shares of the Company will trade at any time. We are not legal, regulatory, accounting or tax experts and have assumed the accuracy and completeness of assessments by the Company and its advisors with respect to legal, regulatory, accounting and tax matters.

We will receive a fee for our services upon the rendering of this opinion. The Company has also agreed to reimburse our expenses and to indemnify us against certain liabilities arising out of our engagement. We will also be entitled to receive a success fee if the Mergers are consummated. Prior to this engagement, we, Evercore Group L.L.C., and its affiliates provided financial advisory services to the Company and had received fees for the rendering of these services including the reimbursement of expenses. During the two year period prior to the date hereof, no material relationship existed between Evercore Group L.L.C. and its affiliates and the Glass Parties pursuant to which compensation was received by Evercore Group L.L.C. or its affiliates as a result of such a relationship. We may provide financial or other services to the Glass Parties in the future and in connection with any such services we may receive compensation.

In the ordinary course of business, Evercore Group L.L.C. or its affiliates may actively trade the securities, or related derivative securities, or financial instruments of the Company and its affiliates, for its own account and for the accounts of its customers and, accordingly, may at any time hold a long or short position in such securities or instruments.

This letter, and the opinion expressed herein is addressed to, and for the information and benefit of, the Board of Directors of the Company in connection with its evaluation of the proposed Mergers. The issuance of this opinion has been approved by an Opinion Committee of Evercore Group L.L.C.

This opinion may not be disclosed, quoted, referred or communicated (in whole or in part) to any third party for any purpose whatsoever except with our prior written approval, except the Company may reproduce this opinion in full in any document that is required to be filed with the U.S. Securities and Exchange Commission and required to be mailed by the Company to its stockholders relating to the Mergers; provided, however, that all references to us or our opinion in any such document and the description or inclusion of our opinion therein shall be subject to our prior consent with respect to form and substance, which consent shall not be unreasonably withheld or delayed.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Solstice Exchange Ratio is fair, from a financial point of view, to the holders of shares of Company Common Stock, and the Total Consideration, taking into account a significant portion of such Total Consideration is in the form of Newco Common Stock, is fair, from a financial point of view, to the Company.

Members of the Board of Directors:

We understand that Sonus Networks, Inc., a Delaware corporation (the "Company"), entered into an Agreement and Plan of Merger, dated as of May 23, 2017 (the "Merger Agreement"), with Solstice Sapphire Investments, Inc., a Delaware corporation and a direct wholly owned subsidiary of the Company ("Newco"), Solstice Sapphire, Inc., a Delaware corporation and a direct wholly owned subsidiary of Newco ("Solstice Merger Sub"), Green Sapphire Investments LLC, a Delaware limited liability company and a direct wholly owned subsidiary of Newco ("Cayman Merger Sub"), Green Sapphire LLC, a Delaware limited liability company and a direct wholly owned subsidiary of Newco ("GB Merger Sub"), Genband Holdings Company, a Cayman Islands exempted company limited by shares ("Glass"), GENBAND Inc., a Delaware corporation ("GB") and GENBAND II, Inc., a Delaware corporation ("GB II" and together with Glass and GB, the "Glass Parties"), pursuant to which (a) Solstice Merger Sub will merge with and into the Company, with the Company surviving as a direct wholly owned subsidiary of Newco (the "Solstice Merger" and, together with the Glass Mergers (as defined below), the "Mergers"), (b) Cayman Merger Sub will merge with and into Glass, with Glass surviving as a direct or indirect wholly owned subsidiary of the Company (the "Glass Merger"), (c) GB will merge with and into GB Merger Sub, with GB Merger Sub surviving as a direct wholly owned subsidiary of Newco (the "GB Merger") and (d) GB II will merge with and into GB Merger Sub, with GB Merger Sub surviving as a direct wholly owned subsidiary of Newco (the "GB II Merger" and, together with the Glass Merger and the GB Merger, the "Glass Mergers").

As a result of (a) the Solstice Merger, each share of common stock, par value $0.001 per share, of the Company (the "Company Common Stock") issued and outstanding immediately prior to the Effective Time (as defined in the Merger Agreement), other than the Excluded Solstice Shares (as defined in the Merger Agreement) will be converted into the right to receive one share of common stock, par value $0.01 per share ("Newco Common Stock"), of Newco (the "Solstice Exchange Ratio"), and (b) the Glass Mergers, among other things, (i) each share of common stock, par value $0.001 per share, of GB issued and outstanding immediately prior to the Effective Time, other than the Excluded GB Shares and Dissenting Shares (each as defined in the Merger Agreement), will be converted into the right to receive a number of shares of Newco Common Stock equal to one multiplied by the GB Exchange Ratio (as defined in the Merger Agreement), (ii) each share of common stock, par value $0.001 per share, of GB II issued and outstanding immediately prior to the Effective Time, other than the Excluded GB II Shares and Dissenting Shares (each as defined in the Merger Agreement), will be converted into the right to receive a number of shares of Newco Common Stock equal to one multiplied by the GB II Exchange Ratio (as defined in the Merger Agreement), and (iii) each share of capital stock or other equity interest of Glass (the "Glass Shares") issued and outstanding immediately prior to the Effective Time, other than the Excluded Glass Shares and Held Glass Shares (each as defined in the Merger Agreement), will be converted into the right to receive (A) that number of shares of Newco Common Stock and (B) that portion of the Promissory Note (as defined in the Merger Agreement) that the holder of such Glass Share is entitled to receive as set forth in the Merger Agreement (such portion of the Promissory Note, the "Glass Note Consideration").

Newco Common Stock immediately after the Effective Time. The aggregate amount of Newco Common Stock and Glass Note Consideration to be issued in connection with the Glass Mergers is herein referred to as the "Total Consideration". The terms and conditions of the Mergers are more fully set forth in the Merger Agreement and terms used herein and not defined shall have the meanings ascribed thereto in the Merger Agreement.

On May 22, 2017, we rendered our opinion to the Board of Directors of the Company with respect to the fairness of the Solstice Exchange Ratio, from a financial point of view, to the holders of shares of the Company Common Stock and the fairness of the Total Consideration, taking into account a significant portion of such Total Consideration is in the form of Newco Common Stock, from a financial point of view, to the Company.

On June 22, 2017, management of the Company furnished to us revised estimates of the present value of the net operating losses of the Company and the Glass Parties, together with corresponding revisions to the applicable tax rate estimates, in each case prepared and revised by management of the Company (the "Management Revised Tax Rate and NOL Estimates").

You have asked us to render an additional opinion as to whether, as of May 22, 2017 and taking into account the Management Revised Tax Rate and NOL Estimates, the Solstice Exchange Ratio is fair, from a financial point of view, to the holders of shares of the Company Common Stock and whether the Total Consideration, taking into account a significant portion of such Total Consideration is in the form of Newco Common Stock, is fair, from a financial point of view, to the Company.

We are not legal, regulatory, accounting or tax experts and have assumed the accuracy and completeness of assessments by the Company and its advisors with respect to legal, regulatory, accounting and tax matters.

We will not receive a fee for our services upon the rendering of this opinion. As part of this engagement, we received a fee of $1.5 million for our services in rendering to the Board of Directors of the Company a separate opinion on May 22, 2017. The Company has also agreed to reimburse our expenses and to indemnify us against certain liabilities arising out of our engagement. We will be entitled to receive a success fee if the Mergers are consummated.

During the two year period prior to the date hereof, no material relationship existed between Evercore Group L.L.C. and its affiliates and the Glass Parties pursuant to which compensation was received by Evercore Group L.L.C. or its affiliates as a result of such a relationship.

You have asked us to render our opinion as to whether, taking into account the Sonus Merger, the shares of NewCo Stock and the Promissory Note to be issued in the Genband Merger, GB Merger and GB II Merger (collectively, the "Merger Consideration"), is fair, from a financial point of view, to the holders of Genband Stock, GB Stock, and GB II stock, as a whole.

In the course of performing our reviews and analyses for rendering our opinion, we have:

•
  Reviewed the Agreement dated as of May 23, 2017, and the form of the Promissory Note attached thereto;
•
  Reviewed certain publicly available business and financial information regarding each of Genband and Sonus;
•
  Reviewed certain non-public business and financial information regarding the respective businesses and prospects of each of Genband and Sonus (including certain financial projections for each of Genband and Sonus for the years ended December 31, 2017 through December 31, 2021), all as prepared and provided to us by Genband's senior management;
•
  Reviewed certain estimated cost savings and other combination benefits and estimated costs to achieve the same (collectively, "synergy estimates" or "synergies") expected to result from the Transaction, all as prepared and provided to us by Genband's senior management and discussed with the senior management of Genband and Sonus;
•
  Discussed with the senior management of Genband and Sonus their strategic and financial rationale for the Transaction as well as their views of Genband's and Sonus' businesses, operations, historical and projected financial results and future prospects;
•
  Discussed with the senior management and the Board of Directors of Genband the efforts undertaken to explore Genband's strategic alternatives other than the Transaction;
•
  Reviewed the historical prices, trading multiples and trading activity of the Sonus Stock;
•
  Compared the financial performance of Genband and Sonus and the trading multiples and trading activity of the Sonus Stock with corresponding data for certain other publicly traded companies that we deemed relevant in evaluating Genband and Sonus;
•
  Performed discounted cash flow analyses based on the financial projections for Genband, Sonus, NewCo and the synergy estimates, in each case as furnished to us by Genband's senior management;
•
  Reviewed the pro forma financial results, financial condition and capitalization of NewCo after giving effect to the Transaction; and
•
  Conducted such other studies, analyses, inquiries and investigations as we deemed appropriate.

With respect to the information used in arriving at our opinion:

•
  We have relied upon and assumed the accuracy, completeness and reasonableness of all industry, business, financial, legal, regulatory, tax, accounting, actuarial and other information (including, without limitation, any financial projections, synergy estimates, other estimates and other forward-looking information) furnished by or discussed with Genband or Sonus or obtained from public sources, data suppliers and other third parties.
•
  We (i) do not assume any responsibility, obligation or liability for the accuracy, completeness, reasonableness, achievability or independent verification of, and we have not independently verified, any such information (including, without limitation, any financial projections, synergy estimates, other estimates and other forward-looking information), (ii) express no view, opinion, representation, guaranty or warranty (in each case, express or implied) regarding the

E-2

Table of Contents

reasonableness or achievability of any financial projections, synergy estimates, other estimates and other forward-looking information or the assumptions upon which they are based and (iii) have relied upon the assurances of Genband's senior management that they are unaware of any facts or circumstances that would make such information (including, without limitation, any financial projections, synergy estimates, other estimates and other forward-looking information) incomplete, inaccurate or misleading.

•
  Specifically, with respect to any (i) financial projections, synergy estimates, other estimates and other forward-looking information furnished by or discussed with Genband, (a) we have been advised by Genband's senior management, and we have assumed, that such financial projections, synergy estimates, other estimates and other forward-looking information utilized in our analyses have been reasonably prepared on bases reflecting the best currently available estimates and judgments of Genband's senior management as to the expected future performance of Genband, Sonus, NewCo and the expected amounts and realization of such synergies (and we have assumed that such synergies will be realized in the amounts and at the times projected) and (b) we have assumed that such financial projections, synergy estimates, other estimates and other forward-looking information have been reviewed by Genband's Board of Directors with the understanding that such information will be used and relied upon by us in connection with rendering our opinion and (ii) financial projections, other estimates and/or other forward-looking information obtained by us from public sources, data suppliers and other third parties, we have assumed that such information is reasonable and reliable.

In rendering our opinion, we have analyzed the Transaction as a strategic business combination not involving a sale of control of Genband, and we have not solicited, nor were we asked to solicit, third party acquisition interest in Genband.

In arriving at our opinion, we have not performed or obtained any independent appraisal of the assets or liabilities (including any contingent, derivative or off-balance sheet assets and liabilities) of Genband, Sonus or any other entity or the solvency or fair value of Genband, Sonus or any other entity, nor have we been furnished with any such appraisals. We are not legal, regulatory, tax, consulting, accounting, appraisal or actuarial experts and nothing in our opinion should be construed as constituting advice with respect to such matters; accordingly, we have relied on the assessments of Genband's other advisors with respect to such matters. Genband's senior management has advised us that all tax-affected financial projections, synergy estimates, other estimates and other forward-looking information reflect currently applicable laws and regulations; at the direction of Genband's Board of Directors and senior management, we have not considered or analyzed the impacts of any potential or proposed reform thereof in connection with our opinion and analyses. We are not expressing any view or rendering any opinion regarding the tax consequences of the Transaction to Genband, GB, GB II or their respective equity holders.

In rendering our opinion, we have assumed that, in all respects meaningful to our analyses, (i) the final executed form of the Promissory Note will not differ from the form attached to the Agreement that we have reviewed, (ii) Genband, Sonus and the other parties thereto will comply with all terms of the Transaction Documentation and (iii) the representations and warranties of Genband, Sonus and the other parties thereto contained in the Transaction Documentation are true and correct and all conditions to the obligations of each party to the Transaction Documentation to consummate the Transaction will be satisfied without any waiver, amendment or modification thereof. We also have assumed that the Transaction will be consummated in a timely manner in accordance with the terms of the Transaction Documentation and in compliance with all applicable laws, documents and other requirements, without any delays, limitations, restrictions, conditions, divestiture or other requirements, waivers, amendments or modifications (regulatory, tax-related or otherwise) that would have an effect on Genband, Sonus, NewCo, the other parties to the Transaction Documentation or the Transaction or its contemplated benefits in any way meaningful to our analyses or opinion.

In rendering our opinion, we do not express any view or opinion as to the price or range of prices at which the shares of common stock or other securities of Sonus or NewCo may trade or otherwise be transferable at any time, including subsequent to the announcement or consummation of the Transaction.

We have been engaged solely to render this opinion in connection with the Transaction and will receive a customary fee for such services, a substantial portion of which is contingent on successful consummation of the Transaction. A portion of our compensation is earned upon delivery of our opinion and will be credited against the fee payable upon consummation of the Transaction. In addition, Genband has agreed to reimburse us for certain expenses and to indemnify us against certain liabilities arising out of our engagement.

Aside from our current engagement by Genband, Guggenheim Securities, LLC ("Guggenheim Securities") has not been previously engaged during the past two years by Genband, nor has Guggenheim Securities been previously engaged during the past two years by Sonus, to provide financial advisory or investment banking services for which we received fees. In the ordinary course of our investment banking business, we have worked informally with each of Genband and Sonus on matters unrelated to the Transaction and we regularly call on and have worked with or opposite OEP and its portfolio companies in connection with various potential transactions and other matters unrelated to Genband and Sonus, for which we may receive fees. Guggenheim Securities may seek to provide Genband, Sonus, NewCo and their respective affiliates with certain financial advisory and investment banking services unrelated to the Transaction in the future, for which services Guggenheim Securities would expect to receive compensation.

Guggenheim Securities and its affiliates and related entities engage in a wide range of financial services activities for our and their own accounts and the accounts of our and their customers, including: asset, investment and wealth management; insurance services; investment banking, corporate finance, mergers and acquisitions and restructuring; merchant banking; fixed income and equity sales, trading and research; and derivatives, foreign exchange and futures. In the ordinary course of these activities, Guggenheim Securities or its affiliates and related entities may (i) provide such financial services to Genband, Sonus, other participants in the Transaction or their respective affiliates, subsidiaries, investment funds and portfolio companies, for which services Guggenheim Securities or any of its affiliates and related entities has received, and may receive, compensation and (ii) directly or indirectly, hold long or short positions, trade and otherwise conduct such activities in or with respect to certain bank debt, debt or equity securities and derivative products of or relating to Genband, Sonus, other participants in the Transaction or their respective affiliates, subsidiaries, investment funds and portfolio companies.

Furthermore, Guggenheim Securities or its affiliates and related entities and our or their respective directors, officers, employees, consultants and agents may have investments in Genband, Sonus other participants in the Transaction or their respective affiliates, subsidiaries, investment funds and portfolio companies.

Consistent with applicable legal and regulatory guidelines, Guggenheim Securities has adopted certain policies and procedures to establish and maintain the independence of its research departments and personnel. As a result, Guggenheim Securities' research analysts may hold views, make statements or investment recommendations and publish research reports with respect to Genband, Sonus, other participants in the Transaction or their respective affiliates, subsidiaries, investment funds and portfolio companies and the Transaction that differ from the views of Guggenheim Securities' investment banking personnel.

Our opinion has been provided to Genband's Board of Directors (in its capacity as such) solely for its information and assistance in connection with its evaluation of the Merger Consideration. Our opinion is not intended to be used or relied upon for any other purpose or by any other person or

entity and may not be disclosed publicly, made available to third parties or reproduced, disseminated, quoted from or referred to at any time, in whole or in part, without our prior written consent.

Our opinion and any materials provided in connection therewith do not constitute a recommendation to Genband's Board of Directors with respect to the Transaction, nor does our opinion or any materials provided in connection therewith constitute advice or a recommendation to any holder of Genband's, GB's, GB II's or Sonus' equity as to whether to exercise any approval rights in connection with the Transaction. Our opinion does not address Genband's underlying business or financial decision to pursue the Transaction, the relative merits of the Transaction as compared to any alternative business or financial strategies that might exist for Genband or the effects of any other transaction in which Genband might engage. Our opinion addresses only the fairness, from a financial point of view and as of the date hereof, taking into account the Sonus Merger, of the Merger Consideration to the holders of Genband Stock, GB Stock, and GB II stock, as a whole. We do not express any view or opinion as to (i) any other term, aspect or implication of (a) the Transaction or the Transaction Documentation (including, without limitation, the form or structure of the Transaction) or (b) any other agreement, transaction document or instrument contemplated by the Transaction Documentation or to be entered into or amended in connection with the Transaction or (ii) the fairness, financial or otherwise, of the Transaction to, or of any consideration to be paid to or received by, or the allocation thereof among, the holders of any particular class of securities, creditors or other constituencies of Genband, GB or GB II. Our opinion (i) does not address the individual circumstances of specific holders of Genband's, GB's or GB II's securities (including stock options and warrants) with respect to rights or aspects which may distinguish such holders or Genband's, GB's or GB II's securities (including stock options and warrants) held by such holders, (ii) does not address, take into consideration or give effect to any rights, preferences, restrictions or limitations or other attributes of any such securities (including stock options and warrants) and (iii) does not in any way address proportionate allocation or relative fairness of consideration received by holders of the various classes of Genband's, GB's and GB II's securities, including with respect to the consideration to be received by OEP and its affiliates relative to the consideration to be received by any other holders of such classes of securities. In addition, our opinion cannot be relied upon to support a determination of fair market value or other judgments that may be made by the Board of Directors in allocating the Merger Consideration to holders of the various classes of Genband's, GB's and GB II's securities. Furthermore, we do not express any view or opinion as to the fairness, financial or otherwise, of the amount or nature of any compensation payable to or to be received by any of Genband's, GB's or GB II's directors, officers or employees, or any class of such persons, in connection with the Transaction or otherwise.

Our opinion has been authorized for issuance by the Fairness Opinion and Valuation Committee of Guggenheim Securities. Our opinion is subject to the assumptions, limitations, qualifications and other conditions contained herein and is necessarily based on economic, capital markets and other conditions, and the information made available to us, as of the date hereof. We assume no responsibility for updating or revising our opinion based on facts, circumstances or events occurring after the date hereof.

Based on and subject to the foregoing, it is our opinion that, as of the date hereof, taking into account the Sonus Merger, the Merger Consideration is fair, from a financial point of view, to the holders of Genband Stock, GB Stock, and GB II stock, as a whole.

Very truly yours,

(iii) Has any agreement, arrangement or understanding for the purpose of acquiring, holding, voting (except voting pursuant to a revocable proxy or consent as described in item (B) of subparagraph (ii) of this paragraph (6)), or disposing of such stock with any other person that beneficially owns, or whose affiliates or associates beneficially own, directly or indirectly, such stock.

CERTAIN TRANSACTIONS

The Board of Directors, when considering a tender offer or merger or acquisition proposal, may, to the fullest extent permitted by applicable law, take into account factors in addition to potential economic benefits to stockholders, including without limitation (i) comparison of the proposed consideration to be received by stockholders in relation to the then current market price of the Corporation's capital stock, the estimated current value of the Corporation in a freely negotiated transaction, and the estimated future value of the Corporation as an independent entity, (ii) the impact of such a transaction on the employees, suppliers, and customers of the Corporation and its effect on the communities in which the Corporation operates, and (iii) the impact of such a transaction on the unique corporate culture and atmosphere of the Corporation.

Notwithstanding anything to the contrary herein, for so long as the Stockholders Agreement remains in effect, in the event that any provision herein has a corresponding provision in, or otherwise relates or is applicable to, the Stockholders Agreement, such provision herein shall be interpreted in a manner consistent with, and giving full effect to, the provisions of the Stockholders Agreement. A copy of the Stockholders Agreement will be provided to any stockholder of the Corporation upon request.

2.2 Annual Meeting. The annual meeting of the stockholders shall be held each year on such date and at such time as the Board of Directors may determine. At each annual meeting the stockholders entitled to vote shall elect such members of the Board of Directors as are standing for election, by ballot, and they may transact such other corporate business as may properly be brought before the meeting.

2.3 Quorum. At all meetings of the stockholders the holders of a majority in voting power of the shares of stock issued and outstanding and entitled to vote thereat, present in person or represented by proxy, shall constitute a quorum requisite for the transaction of business except as otherwise provided by law, the Company's Certificate of Incorporation (the "Certificate of Incorporation"), or these by-laws. Whether or not there is such a quorum at any meeting, the chairman of the meeting or the stockholders entitled to vote thereat, present in person or by proxy, by a majority vote, may adjourn the meeting from time to time without notice of such adjourned meeting if the time and place, if any, thereof, are announced at the meeting at which the adjournment is taken. If the adjournment is for more than thirty (30) days, or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting. At such adjourned meeting, at which a quorum shall be present, any business may be transacted that might have been transacted if the meeting had been held as originally called. The stockholders present in person or by proxy at a duly called meeting at which a quorum is present may continue to transact business until adjournment, notwithstanding the withdrawal of enough stockholders to leave less than a quorum.

2.4 Right to Vote; Proxies. Subject to the provisions of the Company's Certificate of Incorporation, each holder of a share or shares of capital stock of the Company having the right to vote at any meeting shall be entitled to one vote for each such share of stock held by him. Any stockholder entitled to vote at any meeting of stockholders may vote either in person or by proxy, but no proxy that is dated more than three years prior to the meeting at which it is offered shall confer the right to vote thereat unless the proxy provides that it shall be effective for a longer period. A proxy may be granted by a writing executed by the stockholder or his authorized agent or by transmission or

G-1

Table of Contents

authorization of transmission of a telegram, cablegram, or other means of electronic transmission to the person who will be the holder of the proxy or to a proxy solicitation firm, proxy support service organization, or like agent duly authorized by the person who will be the holder of the proxy to receive such transmission, subject to the conditions set forth in Section 212 of the General Corporation Law of the State of Delaware, as it may be amended from time to time (the "General Corporation Law"). A proxy shall be irrevocable if it states that it is irrevocable and if, and only as long as, it is coupled with an interest sufficient in law to support an irrevocable power.

2.5 Voting.

(a) At all meetings of stockholders, when a quorum is present, in all matters other than the election of directors, the affirmative vote of the holders of a majority in voting power of the shares of stock present in person or represented by proxy at the meeting and entitled to vote on such matter shall be the act of the stockholders unless a different or minimum vote is required by the Certificate of Incorporation, these by-laws, the rules or regulations of any stock exchange applicable to the Company, or any law or regulation applicable to the Company or its securities, in which case such different or minimum vote shall be the applicable vote on the matter.

(b) At all meetings of stockholders at which directors are to be elected, other than in a Contested Election Meeting (as defined below), when a quorum is present, a nominee for election as a director at such meeting shall be elected to the Board of Directors if the votes cast "for" such nominee's election exceed the votes cast "against" such nominee's election (with "abstentions" and "broker non-votes" not counted as a vote "for" or "against" such nominee's election). In a Contested Election Meeting, when a quorum is present, directors shall be elected by a plurality of the votes of the shares present in person or represented by proxy at such Contested Election Meeting and entitled to vote on the election of directors. If directors are to be elected by a plurality vote, stockholders shall not be permitted to vote against a nominee. A meeting of stockholders shall be a "Contested Election Meeting" if the number of nominees for election as directors exceeds the number of directors to be elected at such meeting, as of the tenth (10th) day preceding the date of the Company's first notice to stockholders of such meeting sent pursuant to Section 2.6 or Section 2.9, as applicable, of these by-laws (the "Determination Date"); provided, however, that if, in accordance with Section 2.12 of these by-laws, stockholders are entitled to nominate persons for election as a director after the otherwise applicable Determination Date, the Determination Date shall instead be the last day on which stockholders are entitled to nominate persons for election as a director in accordance with Section 2.12.

2.6 Notice of Annual Meetings. Unless otherwise provided by law, the Certificate of Incorporation or these by-laws, notice of the date, time, place (if any), and the means of remote communications (if any), by which stockholders and proxyholders may be deemed to be present in person and vote, of each annual meeting of the stockholders shall be given, at least ten (10) days but not more than sixty (60) days prior to the meeting, to each stockholder of record entitled to vote. Such notice shall be given personally or by mail or, to the extent and in the manner permitted by applicable law, by a form of electronic transmission consented to by the stockholder to whom the notice is given. Notices are deemed given as provided in Section 6.2(a) of these by-laws. The Board of Directors may postpone, reschedule or cancel any annual meeting of the stockholders at its discretion, even after notice thereof has been given. Notice need not be given to any stockholder who submits a written waiver of notice signed by him or waives notice by electronic transmission, whether before or after the time of such meeting. Attendance of a stockholder at a meeting of stockholders shall constitute a waiver of notice of such meeting, except when the stockholder attends the meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any annual meeting of the stockholders need be specified in any waiver of notice.

Neither the business to be transacted at, nor the purpose of, any special meeting of the stockholders need be specified in any waiver of notice.

2.10 Inspectors. The Company shall, in advance of any meeting of stockholders, appoint one or more inspectors to act at the meeting and make a written report thereof.

Each inspector, before discharging his or her duties, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according to the best of such inspector's ability. At the meeting for which the inspector or inspectors are appointed, he or they shall, in addition to the duties set forth in Section 231 of the General Corporation Law, receive and take charge of the proxies and ballots, and decide all questions touching on the qualifications of voters, the validity of proxies, and the acceptance and rejection of votes.

The Company may require any proposed nominee to furnish such other information as it may reasonably require to determine the eligibility of such proposed nominee to serve as a director of the Company.

(3) Notwithstanding anything in the second sentence of paragraph (a)(2) of this Section 2.12 to the contrary, in the event that the number of directors to be elected to the Board of Directors of the Company is increased effective at the annual meeting and there is no public announcement by the Company naming the nominees for the additional directorships at least one hundred (100) days prior to the first anniversary of the preceding year's annual meeting, a stockholder's notice required by this Section 2.12 shall also be considered timely, but only with respect to nominees for the additional directorships, if it shall be delivered to the Secretary at the principal executive offices of the Company not later than the close of business on the tenth (10th) day following the day on which such public announcement is first made by the Company.

Notwithstanding the foregoing provisions of this Section 2.12, unless otherwise required by law, if the stockholder (or a qualified representative of the stockholder) does not appear at the annual or special meeting of stockholders of the Company to present a nomination or proposed business, such nomination shall be disregarded and such proposed business shall not be transacted, notwithstanding that proxies in respect of such vote may have been received by the Company. For purposes of this Section 2.12, to be considered a qualified representative of the stockholder, a person must be a duly authorized officer, manager or partner of such stockholder or must be authorized by a writing executed by such stockholder or an electronic transmission delivered by such stockholder to act for such stockholder as proxy at the meeting of stockholders and such person must produce such writing or electronic transmission, or a reliable reproduction of the writing or electronic transmission, at the meeting of stockholders.

2.13 Conduct of Meetings.

Article V—Stock.

5.1 Stock. The shares of the Company shall be represented by certificates, provided that the Board of Directors may provide by resolution or resolutions that some or all of any or all classes or series of its stock shall be uncertificated shares. Any such resolution shall not apply to shares represented by a certificate until such certificate is surrendered to the Company.

Table of Contents

signed such certificate or certificates or whose facsimile signature shall have been used thereon had not ceased to be such officer or officers, transfer agent or registrar of the Company.

If the Company does not issue fractions of a share, it shall (i) arrange for the disposition of fractional interests by those entitled thereto, (ii) pay in cash the fair value of fractions of a share as of the time when those entitled to receive such fractions are determined, or (iii) issue scrip or warrants in registered form (either represented by a certificate or uncertificated) or in bearer form (represented by a certificate) that shall entitle the holder to receive a full share upon the surrender of such scrip or warrants aggregating a full share. A certificate for a fractional share or an uncertificated fractional share shall, but scrip or warrants shall not unless otherwise provided therein, entitle the holder to exercise voting rights, to receive dividends thereon, and to participate in any of the assets of the Company in the event of liquidation. The Board of Directors may cause scrip or warrants to be issued subject to the conditions that they shall become void if not exchanged for certificates representing full shares or uncertificated full shares before a specified date, or subject to the conditions that the shares for which scrip or warrants are exchangeable may be sold by the Company and the proceeds thereof distributed to the holders of scrip or warrants, or subject to any other conditions that the Board of Directors may impose.

5.3 Transfers of Stock. Subject to any transfer restrictions then in force, the shares of stock of the Company shall be transferable only upon its books by the holders thereof in person or by their duly authorized attorneys or legal representatives, and upon the surrender of the certificate or certificates for such shares properly endorsed (or, with respect to uncertificated shares, by delivery of duly executed instructions or in any other manner permitted by applicable law). The Company shall be entitled to treat the holder of record of any share or shares of stock as the holder in fact thereof and accordingly shall not be bound to recognize any equitable or other claim to or interest in such share on the part of any other person whether or not it shall have express or other notice thereof save as expressly provided by the laws of Delaware.

5.4 Record Date. For the purpose of determining the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, or entitled to receive payment of any dividend or other distribution or the allotment of any rights, or entitled to exercise any rights in respect of any change, conversion, or exchange of stock or for the purpose of any other lawful action, the Board of Directors may fix, in advance, a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which record date shall not be more than sixty (60) days nor less than ten (10) days before the date of such meeting, nor more than sixty (60) days prior to any other action. If no such record date is fixed by the Board of Directors, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held; and the record date for determining stockholders for any other purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto. A determination of stockholders of record entitled to notice of or to vote at any meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board of Directors may fix a new record date for the adjourned meeting.

5.5 Transfer Agent and Registrar. The Board of Directors may appoint one or more transfer agents or transfer clerks and one or more registrars and may require all certificates of stock to bear the signature or signatures of any of them.

(b) Reserves. Before payment of any dividend, there may be set aside out of any funds of the Company lawfully available for dividends such sum or sums as the directors from time to time, in their absolute discretion, think proper as a reserve or reserves to meet contingencies, or for equalizing dividends, or for repairing or maintaining any property of the Company, or for such other purpose as the directors shall think conducive to the interest of the Company, and the directors may modify or abolish any such reserve in the manner in which it was created.

5.7 Lost, Stolen, or Destroyed Certificates. No certificates for shares of stock of the Company (or uncertificated shares, as the case may be) shall be issued in place of any certificate alleged to have been lost, stolen, or destroyed, except upon production of such evidence of the loss, theft, or destruction and upon indemnification of the Company and its agents to such extent and in such manner as the Board of Directors may from time to time prescribe.

5.8 Inspection of Books. Any stockholder, in person or by attorney or other agent, shall, upon written demand under oath stating the purpose thereof, have the right during the usual hours for business to inspect for any proper purpose the Company's stock ledger, a list of its stockholders, and its other books and records; and no stockholder shall have any right to inspect any account or book or document of the Company except as conferred by law.

6.2 Notices.

(a) Notices to directors may be given personally or by telephone, mail, facsimile, electronic mail or other electronic transmission to the extent and in the manner permitted by applicable law. Notices to stockholders may be given personally or by mail or, to the extent and in the manner permitted by applicable law, by a form of electronic transmission consented to by the stockholder to whom the notice is given. In accordance with Section 232 of the General Corporation Law, notices are deemed given (i) if by mail, when deposited in the United States mail, postage prepaid, directed to the stockholder at such stockholder's address as it appears on the records of the Company, or, if a stockholder shall have filed with the Secretary of the Company a written request that notices to such stockholder be mailed to some other address, then directed to such stockholder at such other address; (ii) if by facsimile, when directed to a number at which the stockholder has consented to receive notice; (iii) if by electronic mail, when directed to an electronic mail address at which the stockholder has consented to receive such notice; (iv) if by posting on an electronic network together with a separate notice to the stockholder of such specific posting, upon the later to occur of (A) such posting and (B) the giving of such separate notice of such posting; and (v) if by any other form of electronic transmission, when directed to the stockholder in the manner consented to by the stockholder. Notice shall be deemed to have been given to all stockholders of record who share an address if notice is given in accordance with Section 233 of the General Corporation Law. An affidavit of the Secretary, Assistant Secretary or any transfer agent of the Company that the notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein.

(b) Whenever any notice is required to be given under the provisions of any applicable law or of the Company's Certificate of Incorporation or of these by-laws, a written waiver of notice,

G-13

Table of Contents

signed by the person or persons entitled to said notice, or a waiver of notice by electronic transmission, whether before or after the time stated therein or the meeting or action to which such notice relates, shall be deemed equivalent to notice. Attendance of a person at a meeting shall constitute a waiver of notice of such meeting except when the person attends a meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened.

6.3 Conflict of Interest. No contract or transaction between the Company and one or more of its directors or officers, or between the Company and any other corporation, partnership, association, or other organization in which one or more of its directors or officers are directors or officers, or have a financial interest, shall be void or voidable solely for this reason, or solely because the director or officer is present at or participates in the meeting of the board or committee thereof that authorized the contract or transaction, or solely because any such director's or officer's votes are counted for such purpose, if: (i) the material facts as to the director's or officer's relationship or interest and as to the contract or transaction are disclosed or are known to the Board of Directors or the committee, and the Board of Directors or committee in good faith authorizes the contract or transaction by the affirmative vote of a majority of the disinterested directors, even though the disinterested directors be less than a quorum; or (ii) the material facts as to the director's or officer's relationship or interest and as to the contract or transaction are disclosed or are known to the stockholders of the Company entitled to vote thereon, and the contract or transaction as specifically approved in good faith by vote of such stockholders; or (iii) the contract or transaction is fair as to the Company as of the time it is authorized, approved, or ratified, by the Board of Directors, a committee or the stockholders. Common or interested directors may be counted in determining the presence of a quorum at a meeting of the Board of Directors or of a committee that authorizes the contract or transaction.

6.4 Voting of Securities Owned by the Company. Subject always to the specific directions of the Board of Directors, (i) any shares or other securities issued by any other entity and owned or controlled by the Company may be voted in person at any meeting of security holders of such other entity by the President of the Company if he is present at such meeting, or in his absence by the Treasurer of the Company if he is present at such meeting, and (ii) whenever, in the judgment of the President, it is desirable for the Company to execute a proxy or written consent in respect to any shares or other securities issued by any other entity and owned by the Company, such proxy or consent shall be executed in the name of the Company by the President, without the necessity of any authorization by the Board of Directors, affixation of corporate seal or countersignature or attestation by another officer, provided that if the President is unable to execute such proxy or consent by reason of sickness, absence from the United States or other similar cause, the Treasurer may execute such proxy or consent. Any person or persons designated in the manner above stated as the proxy or proxies of the Company shall have full right, power and authority to vote the shares or other securities issued by such other entity and owned by the Company the same as such shares or other securities might be voted by the Company.

Article VII—Indemnification.

7.1 Right to Indemnification. Each person who was or is made a party or is threatened to be made a party to or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (a "Proceeding"), by reason of being or having been a director or officer of the Company or, while a director or officer of the Company, serving or having served at the request of the Company as a director, trustee, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan (an "Indemnitee"), shall be indemnified and held harmless by the Company to the fullest extent permitted by applicable law, as the same exists or may hereafter be amended, against all expense, liability and loss (including attorneys' fees, judgments, fines, ERISA excise taxes or penalties

G-14

Table of Contents

and amounts paid in settlement) reasonably incurred or suffered by such Indemnitee in connection therewith and such indemnification shall continue as to an Indemnitee who has ceased to be a director, trustee, officer, employee, or agent and shall inure to the benefit of the Indemnitee's heirs, executors, and administrators; provided, however, that, except as provided in Section 7.2 hereof with respect to Proceedings to enforce rights to indemnification or Advancement of Expenses, the Company shall indemnify any such Indemnitee in connection with a Proceeding (or part thereof) initiated by such Indemnitee only if such Proceeding (or part thereof) was approved by the Board of Directors of the Company. The right to indemnification conferred in this Article 7 shall be a contract right and shall include the right to be paid by the Company the expenses (including attorneys' fees) incurred in defending any such Proceeding in advance of its final disposition (an "Advancement of Expenses"); provided, however, that, to the extent required by law, such Advancement of Expenses shall be made only upon the Company's receipt of an undertaking (an "Undertaking"), by or on behalf of such Indemnitee, to repay all amounts so advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal (a "Final Adjudication") that such Indemnitee is not entitled to be indemnified for such expenses under this Article 7 or otherwise.

7.2 Right of Indemnitee to Bring Suit. If a claim under Section 7.1 hereof is not paid in full by the Company within sixty days after a written claim has been received by the Company, except in the case of a claim for an Advancement of Expenses, in which case the applicable period shall be twenty days, the Indemnitee may at any time thereafter bring suit against the Company to recover the unpaid amount of the claim. If successful in whole or in part in any such suit, or in a suit brought by the Company to recover an Advancement of Expenses pursuant to the terms of an Undertaking, the Indemnitee shall be entitled to be paid also the expense of prosecuting or defending such suit to the fullest extent permitted by applicable law. In (i) any suit brought by the Indemnitee to enforce a right to indemnification hereunder (but not in a suit brought by the Indemnitee to enforce a right to an Advancement of Expenses) it shall be a defense that, and (ii) in any suit by the Company to recover an Advancement of Expenses pursuant to the terms of an Undertaking the Company shall be entitled to recover such expenses upon a Final Adjudication that, the Indemnitee has not met the applicable standard of conduct set forth in Section 145 of the General Corporation Law. Neither the failure of the Company (including its Board of Directors, independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such suit that indemnification of the Indemnitee is proper in the circumstances because the Indemnitee has met the applicable standard of conduct set forth in Section 145 of the General Corporation Law, nor an actual determination by the Company (including its Board of Directors, independent legal counsel, or its stockholders) that the Indemnitee has not met such applicable standard of conduct, shall create a presumption that the Indemnitee has not met the applicable standard of conduct or, in the case of such a suit brought by the Indemnitee, be a defense to such suit. In any suit brought by the Indemnitee to enforce a right to indemnification or to an Advancement of Expenses hereunder, or by the Company to recover an Advancement of Expenses pursuant to the terms of an Undertaking, the burden of proving that the Indemnitee is not entitled to be indemnified, or to such Advancement of Expenses, under this Article 7 or otherwise shall be on the Company.

7.3 Non-Exclusivity of Rights. The rights to indemnification and to the Advancement of Expenses conferred in this Article 7 shall not be exclusive of any other right that any person may have or hereafter acquire under any law, the Company's Certificate of Incorporation, these by-laws, agreement, vote of stockholders or disinterested directors or otherwise.

7.4 Insurance. The Company may maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the Company or another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss, whether or not the Company would have the power to indemnify such person against such expense, liability or loss under this Article 7 or under the General Corporation Law.

G-15

Table of Contents

7.5 Indemnification of Employees and Agents of the Company. The Company may, to the extent authorized from time to time by the Board of Directors, grant rights to indemnification, and to the Advancement of Expenses, to any employee or agent of the Company to the fullest extent of the provisions of this Article 7 with respect to the indemnification and Advancement of Expenses of directors and officers of the Company.

7.6 Amendment or Repeal. Any repeal or modification of the foregoing provisions of this Article VII shall not adversely affect any right or protection hereunder of any Indemnitee in respect of any act or omission occurring prior to the time of such repeal or modification.

Article VIII—Amendments.

8.1 Amendments. Subject always to any limitations imposed by the Company's Certificate of Incorporation, these by-laws may be altered, amended, or repealed, or new by-laws may be adopted, by resolution of the Board of Directors duly adopted by a majority of the Whole Board, including (for so long as the Stockholders Agreement remains in effect) the approval of a majority of the Independent Directors. With respect to the power of holders of capital stock to adopt, amend and repeal by-laws of the Company, notwithstanding any other provision of these by-laws or any provision that might otherwise permit a lesser vote or no vote, in addition to any vote of the holders of any class or series of capital stock of the Company required herein or by law, the affirmative vote of the holders of the voting power of at least 662/3% of the shares of the Company's stock entitled to vote thereon, voting together as a single class, shall be required for any such alteration, amendment, repeal, or adoption by the vote of the holders of any class or series of the capital stock of the Company.

(l) Severability. If any provision (or part thereof) of this Agreement is invalid, illegal or unenforceable, that provision (or part thereof) will, to the extent possible, be modified in such a manner as to be valid, legal and enforceable but so as to retain most nearly the intent of the parties as expressed herein, and if such a modification is not possible, that provision (or part thereof) will be severed from this Agreement, and in either case the validity, legality and enforceability of the remaining provisions of (or parts thereof) this Agreement will not in any way be affected or impaired thereby. If any provision (or part thereof) of this Agreement is so broad as to be unenforceable, the provision (or part thereof) shall be interpreted to be only so broad as is enforceable.

(m) Enforcement of Agreement. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with its specific terms or if this Agreement was otherwise breached and that monetary damages, even if available, would not be an adequate remedy hereunder. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any Delaware Court without proof of actual damages and each party hereto waives any requirement for the securing or posting of any bond in connection with such remedy, this being in addition to any other remedy to which they are entitled at law or in equity. The parties further agree not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to Applicable Law or in equity for any reason, nor to assert that a remedy of monetary damages would provide an adequate remedy for such breach.

SECTION IV. TRANSFER RESTRICTIONS

4.1 Transfer Restrictions.

(a) Except as otherwise approved by a majority of the Independent Directors then serving on the Board of Directors, during the period of one hundred and eighty (180) days after the Effective Date (the "Initial Lock-Up Period"), no Stockholder may Transfer any voting Shares that it Beneficially Owns to any Person, other than, in the case of OEP Stockholders, a Permitted Transferee or as may be required as a result of a Regulatory Requirement.

(b) From and after the end of the Initial Lock-Up Period and until the third (3rd) anniversary of the Effective Date, except as otherwise approved by a majority of the Independent Directors then serving on the Board of Directors, no Stockholder may Transfer any voting Shares that it Beneficially Owns to any Person, other than a Permitted Transferee or, in the case of JPMorgan Chase & Co. and its controlled Affiliates, as may be required as a result of a Regulatory Requirement, if:

(i) such Transfer (or series of related Transfers) involves more than fifteen percent (15%) of the then outstanding voting Shares; or

(ii) such Transferee (together with its Affiliates), to the knowledge of such Stockholder, would Beneficially Own, after giving effect to such Transfer (or series of related Transfers), more than fifteen percent (15%) of the then outstanding voting Shares; provided, that the foregoing restriction shall not apply to a Transfer made by such Stockholder in a block trade (without knowledge by such Stockholder of the identity of the ultimate Transferee at the time of such Transfer) to a broker-dealer that is instructed by such Stockholder to comply with the Transfer restrictions of this Section IV with respect to any subsequent Transfer by such broker-dealer to the ultimate Transferee.

(c) Until such time as when the OEP Stockholders no longer have a right to designate any Investor Designees under Section 2.1(a)(ii), and except as otherwise approved by a majority of the Independent Directors then serving on the Board of Directors, no OEP Stockholder may Transfer pursuant to Rule 144 under the Securities Act (other than in a privately negotiated sale, including block trades) any voting Shares that it Beneficially Owns if after giving effect to such Transfer (or series of related Transfers) such Stockholder (together with its Affiliates), in the aggregate, would Transfer more than one percent (1%) of the then outstanding voting Shares in any one (1) calendar quarter. For the avoidance of doubt, the restrictions in this Section 4.1(c) do not apply to a bona fide public offering pursuant to an effective registration statement filed under the Securities Act, including pursuant to the Registration Rights Agreement.

(d) The restrictions in Section 4.1(b) shall not apply with respect to any Transferee that agrees in writing to (and to cause any subsequent Transferee to) be bound by, and comply with, the terms and conditions of Sections 3.1 of this Agreement by executing a Joinder Agreement with respect to such Section or, in the alternative, enters into a separate agreement with the Company (the "Standstill Agreement") that contains standstill restrictions that are at least as favorable to the Company as the terms of and conditions of Section 3.1; provided, however, that the terms and conditions of Section 3.1 or the corresponding requirements of the Standstill Agreement, as applicable, shall terminate and no longer apply with respect to any such Transferee (or subsequent Transferee, as the case may be) upon the earlier of (i) the third (3rd) anniversary of the Effective Date and (ii) such date as when such Transferee (or subsequent Transferee, as the case may be) and its Affiliates, in the aggregate, Beneficially Own not more than fifteen percent (15%) of the then outstanding voting Shares.

I-15

Table of Contents

Upon notice given by the OEP Stockholder to the Company that the OEP Stockholder is exploring a potential transfer of its Shares, which notice shall be given to the Company at least fifteen (15) days prior to the proposed Transfer, the Company shall negotiate in good faith and use its commercially reasonable efforts to enter into a customary confidentiality agreement with any potential Transferee identified by the OEP Stockholder to the Company and to enter a Standstill Agreement and such other related and customary transfer documentation with a Transferee (as applicable).

(e) Notwithstanding any restrictions in Section 4.1 (but subject to Section 2.4 and Section 4.2), each Stockholder shall be permitted to tender any voting Shares it Beneficially Owns pursuant to a public tender offer made to all holders of Shares so long as a majority of the Independent Directors then serving on the Board of Directors has recommended to the holders of Shares that they accept such tender offer and tender their Shares in such tender offer.

4.2 Change of Control Transactions. The OEP Stockholders shall not enter into any definitive agreement with any Person providing for a Change of Control Transaction or participate in or in any way support, assist, facilitate or encourage any other Person to effect or seek, directly or indirectly, a Change of Control Transaction, including by Transferring any Shares in connection with a public tender or similar takeover offer made to all holders of Shares for all Shares, in each case, if as a result of such Change of Control Transaction the OEP Stockholders or their Affiliates would receive per Share consideration in excess of the per Share consideration to be received by the other holders of Shares (provided, however, that if the holders of Shares are granted the right to elect to receive one of two or more alternative forms of consideration, the foregoing provision shall be deemed satisfied if each holder of Shares is granted identical election rights), except as otherwise approved by a majority of the Independent Directors then serving on the Board of Directors.

4.3 Legend. Each OEP Stockholder consents to the placement of the following legend on any Certificate representing Shares:

"THE SALE OR OTHER DISPOSITION OF ANY OF THE SHARES REPRESENTED BY THIS CERTIFICATE IS RESTRICTED BY THE PRINCIPAL STOCKHOLDERS AGREEMENT, DATED AS OF [ ], 2017, AS AMENDED FROM TIME TO TIME, AMONG CERTAIN OF THE STOCKHOLDERS OF THIS CORPORATION AND THIS CORPORATION (THE "AGREEMENT"). A COPY OF THE AGREEMENT IS AVAILABLE FOR INSPECTION DURING NORMAL BUSINESS HOURS AT THE PRINCIPAL EXECUTIVE OFFICE OF THIS CORPORATION."

The Company may also place stop-transfer instructions in respect of such Shares with respect to such legend.

SECTION V. PREEMPTIVE RIGHTS

5.1 Preemptive Rights.

(a) For as long as the OEP Stockholders have a right to designate two (2) or more Investor Designees under Section 2.1(a)(ii), each OEP Stockholder shall have the right to purchase, in accordance with the procedures set forth herein, its pro rata portion, calculated based on the percentage of the total issued and outstanding voting Shares owned by such OEP Stockholder immediately prior to issuance of the New Shares ("Pro Rata Portion") of any New Shares that the Company may, from time to time, propose to sell and issue (hereinafter referred to as the "Preemptive Right").

I-16

Table of Contents

(b) In the event that the Company proposes to issue and sell New Shares, the Company shall notify the OEP Stockholders in writing with respect to the proposed New Shares to be issued (the "New Shares Notice"). Each New Shares Notice shall set forth: (i) the number of New Shares proposed to be issued by the Company and the purchase price therefor; (ii) each OEP Stockholder's Pro Rata Portion of such New Shares; and (iii) any other material term (including, if known, the expected date of consummation of the purchase and sale of the New Shares).

(c) The OEP Stockholders shall be entitled to exercise their right to purchase New Shares by delivering an irrevocable written notice to the Company within twenty (20) days from the date of receipt of any such New Shares Notice specifying the number of New Shares to be subscribed, which in any event can be no greater than each OEP Stockholder's Pro Rata Portion of such New Shares at the price and on the terms and conditions specified in the New Shares Notice.

(d) If any OEP Stockholder does not elect within the applicable notice period described above to exercise its Preemptive Rights with respect to any of the New Shares proposed to be sold by the Company, the Company shall have one hundred twenty (120) days after expiration of such notice period to sell such unsubscribed New Shares proposed to be sold by the Company, at a price and on terms no more favorable to the purchaser than those set forth in the New Shares Notice. If the Company does not consummate the sale of the unsubscribed New Shares in accordance with the terms of the New Shares Notice within such one hundred twenty (120)-day period, then the Company may not issue or sell such New Shares unless it sends a new New Shares Notice and once again complies with the provisions of this Section 5.1 with respect to such New Shares. A failure by any OEP Stockholder to exercise its Preemptive Rights with respect to any of the New Shares shall not waive such OEP Stockholder's Preemptive Rights with respect to future issuances of the New Shares.

(e) Each OEP Stockholder shall take up and pay for any New Shares that such OEP Stockholder has elected to purchase pursuant to the Preemptive Right upon closing of the issuance of the New Shares, and shall have no right to acquire such New Shares if the issuance thereof is not consummated.

6.5 Remedies; Severability. It is specifically understood and agreed that any breach of the provisions of this Agreement by any party will result in irreparable injury to the other parties, that the remedy at law alone will be an inadequate remedy for such breach, and that, in addition to any other legal or equitable remedies which they may have, such other parties shall be entitled to enforce their respective rights by bringing actions for specific performance or injunctive relief. If any provision (or part thereof) of this Agreement is invalid, illegal or unenforceable, that provision (or part thereof) will, to the extent possible, be modified in such a manner as to be valid, legal and enforceable but so as to retain most nearly the intent of the parties as expressed herein, and if such a modification is not possible, that provision (or part thereof) will be severed from this Agreement, and in either case the validity, legality and enforceability of the remaining provisions (or parts thereof) of this Agreement will not in any way be affected or impaired thereby.

6.6 Entire Agreement. This Agreement, the Exhibits and any documents delivered by the parties in connection herewith constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and understandings among the parties with respect thereto.

6.8 Governing Law. This Agreement and the rights and obligations of the parties hereto shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware.

6.9 Successors and Assigns; Beneficiaries. No party hereto may assign this Agreement, or any of its rights or obligations under this Agreement, to any Person without the prior written consent of the other parties. Subject to the foregoing sentence, this Agreement shall be binding upon and

I-19

Table of Contents

inure to the benefit of the parties and the respective successors and permitted assigns of the parties as contemplated herein.

6.10 Consent to Jurisdiction; Specific Performance; WAIVER OF JURY TRIAL.

(a) Each of the parties hereby irrevocably agrees that any legal action or proceeding with respect to this Agreement, the Transactions, and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement, the Transactions, and the rights and obligations arising hereunder brought by the other party hereto or its successors or assigns, shall be brought and determined exclusively in the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (or, if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware) (collectively with Delaware Court of Chancery, the "Delaware Courts"). Each of the parties hereto further agrees not to commence any litigation relating to this Agreement or the Transactions except in the Delaware Courts, waives any objection to the laying of venue of any such litigation in the Delaware Courts and agrees not to plead or claim in any Delaware Court that such litigation brought therein has been brought in an inconvenient forum. The choice of forum set forth in this Section shall not be deemed to preclude the enforcement of any judgment of a Delaware federal or state court, or the taking of any action under this Agreement to enforce such a judgment, in any other appropriate jurisdiction.

(b) EACH PARTY TO THIS AGREEMENT IRREVOCABLY WAIVES THE RIGHT TO A TRIAL BY JURY IN CONNECTION WITH ANY MATTER ARISING OUT OF THIS AGREEMENT AND, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY DEFENSE OR OBJECTION IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY PROCEEDING UNDER THIS AGREEMENT BROUGHT IN THE DELAWARE COURTS AND ANY CLAIM THAT ANY PROCEEDING UNDER THIS AGREEMENT BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. EACH PARTY TO THIS AGREEMENT CERTIFIES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT OR INSTRUMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS SET FORTH ABOVE IN THIS SECTION 6.10. NO PARTY HAS IN ANY WAY AGREED WITH OR REPRESENTED TO ANY OTHER PARTY THAT THE PROVISIONS OF THIS SECTION WILL NOT BE FULLY ENFORCED IN ALL INSTANCES.

6.11 Further Assurances; Company Logo. At any time or from time to time after the Effective Date, the parties hereto agree to cooperate with each other, and at the request of any other party, to execute and deliver any further instruments or documents and to take all such further action as any other party may reasonably request in order to evidence or effectuate the provisions of this Agreement and to otherwise carry out the intent of the parties hereunder. The Company hereby grants the OEP Stockholders and their respective Affiliates permission to use the Company's and its subsidiaries' name and logo in marketing materials.

6.12 Competitive Opportunity. If any Stockholder or any of its Affiliates acquires knowledge of a potential transaction or matter which may be an investment or business opportunity or prospective economic or competitive advantage in which the Company could have an interest or expectancy (a "Competitive Opportunity") or otherwise is then exploiting any Competitive Opportunity, then, except with respect to any Competitive Opportunity described in the following sentence of this Section 6.12, the Company shall have no interest in, and no expectation that, such Competitive Opportunity be offered to it, any such interest or expectation being hereby renounced so that each Stockholder (other than any such Stockholder who is bound by any employment,

I-20

Table of Contents

consulting, non-competition or other agreements that prohibit such actions) shall (i) have no duty to communicate or present such Competitive Opportunity to the Company and (ii) have the right to hold any such Competitive Opportunity for such Stockholder's (and its agents', partners' or Affiliates') own account and benefit or to recommend, assign or otherwise transfer such Competitive Opportunity to Persons other than the Company or any Affiliate of the Company. Notwithstanding the foregoing, as long as the OEP Stockholders have a right to designate an Investor Designee and to the extent that the Company identifies a Competitive Opportunity to an Investor Designee that (i) the Investor Designee and the OEP Stockholders did not have knowledge of prior to receipt of such notice, (ii) the Board of Directors resolves to cause the Company to pursue, and (iii) the Board of Directors determines the Company has or is reasonably capable of obtaining the requisite funding to pursue, then no OEP Stockholder may seek the assistance of such Investor Designee, and such Investor Designee shall not assist any OEP Stockholder, in pursuing such Competitive Opportunity until such time as the Company ceases to pursue such Competitive Opportunity. Notwithstanding anything to the contrary contained in this Agreement or any other agreement, none of the provisions of this Agreement or any other agreement shall in any way limit the activities of the OEP Stockholders and their Affiliates in their businesses unrelated to the Company and its Subsidiaries or in making investments.

6.13 Recapitalization, Exchange, Etc. Affecting the Shares. The provisions of this Agreement shall apply, to the full extent set forth herein, with respect to any and all Shares or equity securities of any successor or assign of the Company (whether by merger, consolidation, sale of assets, conversion to a corporation or otherwise) that may be issued in respect of, in exchange for, or in substitution of, the Shares and shall be appropriately adjusted for any dividends, splits, reverse splits, combinations, recapitalizations, and the like occurring after the Effective Date.

6.14 No Recourse. Notwithstanding anything that may be expressed or implied in this Agreement, the Company and each Stockholder covenant, agree and acknowledge that no recourse under this Agreement or any document or instrument delivered in connection with this Agreement shall be had against any current or future director, officer, employee, agent, general or limited partner or member of any Stockholder or any Affiliate or assignee thereof, as such, whether by the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any statute, regulation or other Applicable Law, it being expressly acknowledged that no personal liability whatsoever shall attach to, be imposed upon or otherwise be incurred by any current or future director, officer, employee, agent, general or limited partner or member of any Stockholder or any Affiliate or assignee thereof, as such, for any obligation of any Stockholder under this Agreement or any documents or instruments delivered in connection with this Agreement for any claim based on, in respect of or by reason of such obligations or their creation.

REGISTRATION RIGHTS

SECTION 2.01 Demand Registration. (a) Registration. Subject to the terms hereof and of the Stockholders Agreement, at any time after the 180th day following the Closing Date, any Stockholder or group of Stockholders holding at least 2.5% of the outstanding Shares (collectively, the "Demand Right Holders") shall be entitled to make a written request of the Company (a "Demand" and any Demand Right Holders that makes such written request, the "Requesting Stockholders") for registration under the Securities Act of an amount equal to or greater than the Registrable Amount (a "Demand Registration") and thereupon the Company will, subject to the terms of this Agreement, use its reasonable best efforts to effect, as promptly as reasonably practicable, the registration under the Securities Act of:

(i) the Registrable Securities which the Company has been so requested to register by the Requesting Stockholders for disposition in accordance with the intended method of disposition stated in such Demand;

(ii) all other Registrable Securities which the Company has been requested to register pursuant to Section 2.01(b), but subject to Section 2.01(g); and

(iii) all Shares which the Company may elect to register in connection with any offering of Registrable Securities pursuant to this Section 2.01, but subject to Section 2.01(g);

all to the extent necessary to permit the disposition (in accordance with the intended distribution methods in such request) of the Registrable Securities and the additional Shares, if any, to be so registered.

(b) Demands; Demand Participation. A Demand shall specify: (i) the aggregate number of Registrable Securities requested to be registered in such Demand Registration, (ii) the intended method of disposition in connection with such Demand Registration, to the extent then known, and (iii) the identity of the Requesting Stockholder(s). Within five Business Days after receipt of a Demand, the Company shall give written notice of such Demand to each other Stockholder that holds any Registrable Securities. Subject to Section 2.01(g), the Company shall include in such registration all Registrable Securities with respect to which the Company has received a written request for inclusion therein within ten Business Days after the Company's notice required by this paragraph has been given (such participating Stockholders, the "Demand Participating Stockholders"). Such written notice shall include the same information included in the written request of the Requesting Stockholder(s) delivered pursuant to this Section 2.01(b).

(c) Number of Demands. The Demand Right Holders (collectively) shall be entitled to unlimited Demand Registrations during the term of this Agreement.

(d) Effective Registration Statement. A Demand Registration shall not be deemed to have been effected and shall not count as a Demand (i) unless a registration statement with respect thereto has become effective and has remained effective for a period of at least 120 days (or two years in the case of a Shelf Registration Statement) or such shorter period in which all Registrable Securities included in such registration statement have actually been sold thereunder (provided that such period shall be

J-4

Table of Contents

extended for a period of time equal to the period the holder of Registrable Securities refrains from selling any securities included in the effective registration statement at the request of the Company or the lead or co-managing underwriter(s) pursuant to the provisions of this Agreement), (ii) if, after it has become effective, but before any of the circumstances in clause (i) are satisfied, such registration statement becomes subject to any stop order, injunction or other order or requirement of the Commission or other Governmental Authority for any reason, or (iii) if the conditions to closing specified in the purchase agreement or underwriting agreement entered into in connection with such registration statement are not satisfied, other than by reason of some act or omission by such Requesting Stockholders.

(e) Registration Statement Form. Demand Registrations shall be on such appropriate registration form of the Commission as shall be selected by the Company and shall be reasonably acceptable to the Requesting Stockholder.

(f) Restrictions on Demand Registrations. The Company shall not be obligated to (i) maintain the effectiveness of a registration statement under the Securities Act, filed pursuant to a Demand Registration, for a period longer than 120 days (or, in the case of a Shelf Registration Statement, two years), or (ii) effect any Demand Registration (A) within 90 days of a "firm commitment" underwritten registration in which all Stockholders holding a Registrable Amount were given piggyback rights pursuant to Section 2.02 (subject to Section 2.02(b)) and at least 80% of the number of Registrable Securities requested by such Stockholders to be included in such registration statement were included, (B) within three months of any other Demand Registration, or (C) if, in the Company's reasonable judgment, it is not feasible for the Company to proceed with the Demand Registration because of the unavailability of audited financial statements. In addition, the Company shall be entitled to postpone the filing of a registration statement or the facilitation of a registered offering (upon written notice to all Stockholders) in the event of a Blackout Period until the expiration of the applicable Blackout Period. The Company may not postpone the filing of a registration statement or the facilitation of a registered offering more than twice in any period of 12 consecutive months, except if required by Applicable Law; provided that if the Company has previously postponed the filing of a registration statement or the facilitation of a registered offering, the Company may not again postpone the effectiveness of such registration statement until 30 days after the expiration of the previous postponement. If the Company postpones the filing or effectiveness of a registration statement for a Demand Registration, the holders of a majority of Registrable Securities held by the Requesting Stockholder(s) shall have the right to withdraw such Demand in accordance with Section 2.04.

(g) Participation in Demand Registrations. The Company shall not include any securities other than Registrable Securities in a Demand Registration, except (i) for Shares that the Company proposes to sell for its own account and (ii) with the written consent (such consent not to be unreasonably withheld, delayed or conditioned) of Stockholders participating in such Demand Registration that hold a majority of the Registrable Securities in such Demand Registration. If, in connection with a Demand Registration, the lead managing or co-managing underwriter(s) advise(s) the Company, in writing, that, in its opinion, the inclusion of all of the securities, including securities of the Company that are not Registrable Securities, sought to be registered in connection with such Demand Registration would adversely affect the distribution of the Registrable Securities sought to be sold pursuant thereto, then the Company shall include in such registration statement only such securities as the Company is advised by such underwriter(s) can be sold without such adverse effect (the "Maximum Amount") as follows and in the following order of priority:

(i) first, the number of Registrable Securities requested to be included in such registration by the Requesting Stockholders up to the Maximum Amount, allocated pro rata among such Requesting Stockholders requesting such registration on the basis of the number of such securities requested to be included by such Stockholders;

J-5

Table of Contents

(ii) second, Shares that the Company proposes to sell which, taken together with the Registrable Securities under clause (i) above, do not exceed the Maximum Amount; and

(iii) third, all other securities of the Company duly requested to be included in such registration statement, pro rata on the basis of the amount of such other securities requested to be included or such other method determined by the Company, to the extent, when taken together with clause (i) and (ii) such number of securities does not exceed the Maximum Amount.

(h) Selection of Underwriters. In connection with a Demand Registration, the Requesting Stockholder(s) may elect to have Registrable Securities sold in an Underwritten Offering. Anytime that a Demand Registration involves an Underwritten Offering, the Requesting Stockholder(s) may select the investment banker or investment bankers and managers that will serve as lead and co-managing underwriters with respect to the offering of such Registrable Securities, subject to the prior written consent of the Company, which consent shall not be unreasonably withheld, delayed or conditioned. In connection with any Underwritten Offering under this Section 2.01, each Demand Participating Stockholder shall be obligated to accept the terms of the underwriting as agreed upon between the Requesting Stockholder(s) and the lead or co-managing underwriters on terms no less favorable to such Demand Participating Stockholders than the Requesting Stockholders(s). In the event of a disagreement among the Requesting Stockholders, the decision of the Stockholder(s) holding a majority of the Registrable Securities shall govern for purposes of this Section 2.01(h).

(i) Demand Withdrawal. The Requesting Stockholder or the Requesting Stockholders (with the consent of the Requesting Stockholder(s) holding a majority of the Registrable Securities), as the case may be, shall have the right to withdraw a Demand in accordance with Section 2.04.

SECTION 2.02 Piggyback Rights. (a) Subject to the terms and conditions hereof and the Stockholders Agreement, whenever the Company proposes to register any of its securities under the Securities Act (other than a registration by the Company (i) on a registration statement on Form S-4 or any successor form, a registration statement on Form S-8 or any successor form or (ii) pursuant to Section 2.01 or 2.03) (a "Piggyback Registration"), the Company shall give the Stockholders prompt written notice thereof (but not less than ten Business Days prior to the filing by the Company with the Commission of any registration statement with respect thereto). Such notice (a "Piggyback Notice") shall specify, at a minimum, the number of securities proposed to be registered, the proposed date of filing of such registration statement with the Commission, the proposed means of distribution, the proposed lead or co-managing underwriter(s) (if any and if known), and a good faith estimate by the Company of the proposed minimum offering price of such securities. Upon the written request of a Stockholder (a "Piggyback Seller") (which written request shall specify the number of Registrable Securities then presently intended to be disposed of by such Stockholder) given within ten days after such Piggyback Notice is sent to such Stockholder, the Company, subject to the terms and conditions of this Agreement, shall use its reasonable best efforts to cause all such Registrable Securities held by Stockholders with respect to which the Company has received such written requests for inclusion to be included in such Piggyback Registration on the same terms and conditions as the Company's securities being sold in such Piggyback Registration.

(b) Priority on Piggyback Registrations. If, in connection with a Piggyback Registration, the lead or co-managing underwriter(s) advise(s) the Company, in writing, that, in its opinion, the inclusion of all the securities sought to be included in such Piggyback Registration by the Company, by others who have sought to have Registrable Securities registered pursuant to any rights to demand registration (other than pursuant to so called "piggyback" or other incidental or participation registration rights described herein) (such demand rights being "Other Demand Rights" and such Persons being "Other Demanding Sellers"), by the Piggyback Sellers and by any other proposed sellers, as the case may be, would adversely affect the distribution of the securities sought to be sold pursuant thereto, then the Company shall include in the registration statement applicable to such Piggyback Registration only such

J-6

Table of Contents

securities as the Company is so advised by such lead or co-managing underwriter(s) can be sold without such an effect, as follows and in the following order of priority:

(i) if the Piggyback Registration is in connection with an offering for the Company's own account, then (A) first, such number of securities to be sold by the Company as the Company, in its reasonable judgment and acting in good faith and in accordance with sound financial practice, shall have determined, (B) second, Registrable Securities of Piggyback Sellers, pro rata on the basis of the amount of such Registrable Securities sought to be registered by such Piggyback Sellers, (C) third, other Shares of the Company sought to be registered by the Other Demanding Sellers and (D) fourth, other shares held by any other proposed sellers; and

(ii) if the Piggyback Registration relates to an offering other than for the Company's own account, then (A) first, such number of Registrable Securities sought to be registered by each Other Demanding Seller, pro rata in proportion to the number of securities sought to be registered by all such Other Demanding Sellers, (B) second, Registrable Securities of Piggyback Sellers pro rata on the basis of the amount of such Registrable Securities sought to be registered by such Piggyback Sellers, (C) third, Shares to be sold by the Company and (D) fourth, other shares of the Company held by any other proposed sellers.

(c) Terms of Underwriting. In connection with any offering under this Section 2.02 involving an underwriting for the Company's account, the Company shall not be required to include a holder's Registrable Securities in the underwritten offering if, after the Company consults with such holder and considers such holder's positions in good faith, such holder refuses to agree to the terms of the underwriting as agreed upon between the Company and the lead or co-managing underwriter(s) whether secured by the Company or otherwise.

(d) Withdrawal by the Company. If, at any time after giving written notice of its intention to register any of its securities as set forth in this Section 2.02 and prior to the time the registration statement filed in connection with such registration is declared effective, the Company shall determine for any reason not to register such securities, the Company may, at its election, give written notice of such determination to each Stockholder and thereupon shall be relieved of its obligation to register any Registrable Securities in connection with such particular withdrawn or abandoned registration (but not from its obligation to pay the Registration Expenses in connection therewith as provided herein); provided that any participating Demand Right Holders may continue the registration as a Demand Registration pursuant to Section 2.01.

SECTION 2.03 Shelf Registration. (a) Subject to the terms hereof and of the Stockholders Agreement, in connection with a Demand Registration, subject to Section 2.03(d), and further subject to the availability of a registration statement on Form S-3 or any successor form ("Form S-3") to the Company, the Requesting Stockholder(s) making the Demand may by written notice delivered to the Company (the "Shelf Notice") require the Company to file as soon as practicable (but no later than 45 days after the date the Shelf Notice is delivered and no earlier than the 180th day following the Closing Date), and to use reasonable best efforts to cause to be declared effective by the Commission as soon as practicable, a Form S-3 providing for an offering to be made on a continuous or delayed basis pursuant to Rule 415 under the Securities Act relating to the offer and sale, from time to time, of the Registrable Securities Beneficially Owned by such Requesting Stockholder(s) and the other Stockholders holding any Registrable Securities who elect to participate therein as provided in Section 2.03(b) in accordance with the plan and method of distribution set forth in the prospectus included in such Form S-3 (the "Shelf Registration Statement"). In the event of a disagreement among the Requesting Stockholders, the decision of the Stockholder(s) holding a majority of the Registrable Securities shall govern for purposes of this Section 2.03(a).

J-7

Table of Contents

(b) Within five Business Days after receipt of a Shelf Notice pursuant to Section 2.03(a), the Company will deliver written notice thereof to each Stockholder holding any Registrable Securities. Each Stockholder may elect to participate in the Shelf Registration Statement in accordance with the plan and method of distribution set forth in such Shelf Registration Statement by delivering to the Company a written request to so participate within ten Business Days after the Shelf Notice is given to any such Stockholders.

(c) Subject to Section 2.03(d), the Company will use reasonable best efforts to keep the Shelf Registration Statement continuously effective until the earlier of (i) two years after the Shelf Registration Statement has been declared effective and (ii) the date on which all Registrable Securities covered by the Shelf Registration Statement have been sold thereunder in accordance with the plan and method of distribution disclosed in the prospectus included in the Shelf Registration Statement, or otherwise.

(d) The Company shall be entitled, from time to time, by providing written notice to the Stockholders who elected to participate in the Shelf Registration Statement, to require such Stockholders to suspend the use of the prospectus for sales of Registrable Securities under the Shelf Registration Statement for any Blackout Period. Immediately upon receipt of such notice, the Stockholders covered by the Shelf Registration Statement shall suspend the use of the prospectus until the requisite changes to the prospectus have been made as required below. After the expiration of any Blackout Period and without any further request from a Stockholder, the Company shall as promptly as reasonably practicable prepare a post-effective amendment or supplement to the Shelf Registration Statement or the prospectus, or any document incorporated therein by reference, or file any other required document so that, as thereafter delivered to purchasers of the Registrable Securities included therein, the prospectus will not include any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to be stated in order to make the statements made, in light of the circumstances under which they were made, not misleading.

(e) At any time that a Shelf Registration Statement is effective, if any Demand Right Holder delivers a notice to the Company (a "Take-Down Notice") stating that it intends to sell all or part of its Registrable Securities included by it on the Shelf Registration Statement in an Underwritten Offering (a "Shelf Offering"), then, the Company shall as promptly as reasonably practicable amend or supplement the Shelf Registration Statement as may be necessary in order to enable such Registrable Securities to be distributed pursuant to the Shelf Offering (taking into account, solely in connection with a Marketed Underwritten Shelf Offering (as defined below), the inclusion of Registrable Securities by any other holders pursuant to this Section 2.03(e)). In connection with any Shelf Offering that is an Underwritten Offering and where the plan of distribution set forth in the applicable Take-Down Notice includes a customary "road show" (including an "electronic road show") or other substantial marketing effort by the Company and the underwriters (a "Marketed Underwritten Shelf Offering"):

(i) the Company shall forward the Take-Down Notice to all other holders of Registrable Securities included on the Shelf Registration Statement and the Company and such proposing Demand Right Holder shall permit each such holder to include its Registrable Securities included on the Shelf Registration Statement in the Marketed Underwritten Shelf Offering if such holder notifies the proposing Demand Right Holder and the Company within five Business Days after delivery of the Take-Down Notice to such holder; and

(ii) if the lead or co-managing underwriter(s) advises the Company and the proposing Demand Right Holder that, in its opinion, the inclusion of all of the securities sought to be sold in connection with such Marketed Underwritten Shelf Offering would adversely affect the distribution thereof, then there shall be included in such Marketed Underwritten Shelf Offering only such securities as the proposing Demand Right Holder is advised by such lead or co-managing underwriter(s) can be sold without such adverse effect, and such number of Registrable Securities

J-8

Table of Contents

shall be allocated in the same manner as described in Section 2.01(g). Except as otherwise expressly specified in this Section 2.03, any Marketed Underwritten Shelf Offering shall be subject to the same requirements, limitations and other provisions of this Article II as would be applicable to a Demand Registration (i.e., as if such Marketed Underwritten Shelf Offering were a Demand Registration), including Section 2.01(f) and Section 2.01(g).

Notwithstanding anything in this Section 2.03 to the contrary, the Company shall not be required to participate in more than two Marketed Underwritten Shelf Offerings per fiscal year.

SECTION 2.04 Withdrawal Rights. Any Stockholder having notified or directed the Company to include any or all of its Registrable Securities in a registration statement under the Securities Act shall have the right to withdraw any such notice or direction with respect to any or all of the Registrable Securities designated by it for registration by giving written notice to such effect to the Company prior to the effective date of such registration statement. In the event of any such withdrawal, the Company shall not include such Registrable Securities in the applicable registration and such Registrable Securities shall continue to be Registrable Securities for all purposes of this Agreement. No such withdrawal shall affect the obligations of the Company with respect to the Registrable Securities not so withdrawn; provided, however, that in the case of a Demand Registration, if such withdrawal shall reduce the number of Registrable Securities sought to be included in such registration below the Registrable Amount, then the Company shall as promptly as practicable give each holder of Registrable Securities sought to be registered notice to such effect and, within ten Business Days following the mailing of such notice, such holder of Registrable Securities still seeking registration shall, by written notice to the Company, elect to register additional Registrable Securities, when taken together with elections to register Registrable Securities by its Affiliates, to satisfy the Registrable Amount or elect that such registration statement not be filed or, if theretofore filed, be withdrawn. During such ten Business Day period, the Company shall not file such registration statement or, if such registration statement has already been filed, the Company shall not seek, and shall use reasonable best efforts to prevent, the effectiveness thereof. Any registration statement withdrawn or not filed (a) in accordance with an election by the Company, (b) in accordance with an election by the Requesting Stockholder in the case of a Demand Registration or with respect to a Shelf Registration Statement or (c) in accordance with an election by the Company subsequent to the effectiveness of the applicable Demand registration statement because any post-effective amendment or supplement to the applicable Demand registration statement contains information regarding the Company which the Company deems adverse to the Company, shall not be counted as a Demand.

SECTION 2.05 Lock-up Agreements. In connection with any Underwritten Offering, each Stockholder agrees to enter into customary agreements to not effect any public sale or distribution (including sales pursuant to Rule 144) of Company Equity Securities (a) for a Public Offering (other than a Demand Registration or Piggyback Registration), during the period between the date specified by the Company to such Stockholder in its notice of intention to commence a Public Offering (such date to be the Company's best estimate as to the date that is 10 days prior to the date of the filing of the "final" prospectus or "final" prospectus supplement if the Underwritten Offering is made pursuant to a Shelf Registration Statement, the "Final Prospectus Filing Date") and 120 days following the Final Prospectus Filing Date or (b) for a Demand Registration or Piggyback Registration, during the period between the date specified by the Company to such Stockholder in its notice of intention to commence an Underwritten Offering (such date to be the Company's best estimate as to the date that is 10 days prior to the Final Prospectus Filing Date) and 90 days following the Final Prospectus Filing Date. For the avoidance of doubt, the lock-up restrictions pursuant to any underwriting agreement to be entered into with the underwriters shall not exceed the time limits on the lock-up restrictions set forth herein without the written consent (such consent not to be unreasonably withheld, delayed or conditioned) of each Demand Right Holder. The Company also shall cause its executive officers and directors (and managers, if applicable) and shall use its reasonable best efforts to cause other holders of Shares who

J-9

Table of Contents

Beneficially Own any of the Shares participating in such offering (including the Company, if applicable), to enter into lockup agreements that contain restrictions that are no less restrictive than the restrictions contained herein. Notwithstanding anything in this Agreement to the contrary, no provision of this Agreement nor any other agreement between any of the OEP Stockholders or their Affiliates, on the one hand, and the Company or its subsidiaries, on the other, shall in any way restrict, prohibit or otherwise restrain JPMorgan Chase & Co. and its Affiliates from operating in the ordinary course business or engaging in their respective ordinary course business activities, whether through its investment banking division or otherwise.

SECTION 2.06 Registration Procedures. (a) Registration. If and whenever the Company is required to use reasonable best efforts to effect the registration of any Registrable Securities under the Securities Act as provided in Sections 2.01, 2.02, and 2.03, the Company shall as promptly as reasonably practicable:

(i) prepare and file with the Commission a registration statement to effect such registration and thereafter use reasonable best efforts to cause such registration statement to become and remain effective, pursuant to the terms of this Agreement; provided, however, that the Company may discontinue any registration of its securities which are not Registrable Securities at any time prior to the effective date of the registration statement relating thereto; provided, further, however, that at least five Business Days prior to filing any registration statement or any amendments thereto, the Company will furnish to the counsel selected by the holders of Registrable Securities which are to be included in such registration ("Selling Holders") copies of all such documents proposed to be filed, which documents will be subject to the review of such counsel (such review to be conducted with reasonable promptness) and other documents reasonably requested by such counsel, including any comment letter from the Commission, and if reasonably requested by such counsel, provide such counsel reasonable opportunity to participate in the preparation of such registration statement and each prospectus included therein and such other opportunities to conduct a reasonable investigation within the meaning of the Securities Act, including reasonable access upon reasonable notice during normal business hours to the Company's books and records, officers, accountants and other advisors, so long as such access or request does not unreasonably disrupt the normal operations of the Company and its subsidiaries. The Company shall not file such registration statement or any amendments thereto if the Selling Holders shall in good faith reasonably object in writing to the filing of such documents, unless, in the good faith opinion of the Company, such filing is necessary to comply with Applicable Law; provided, however, that the Selling Holders shall (and shall cause their representatives to) keep confidential any such information that is not generally publicly available at the time of delivery of such information;

(ii) prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary (A) to keep such registration statement effective, (B) to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement and (C) to not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to be stated in order to make the statements made, in light of the circumstances under which they were made, not misleading, until the earlier of such time as all of such securities have been disposed of in accordance with the intended methods of disposition by Selling Holders thereof set forth in such registration statement or the expiration of 120 days (or two years in the case of a Shelf Registration Statement) after such registration statement becomes effective;

(iii) if requested by the lead or co-managing underwriters, if any, or the holders of a majority of the then outstanding Registrable Securities being sold in connection with an underwritten offering, as promptly as reasonably practicable include in a prospectus supplement or post-effective amendment such information as the lead or co-managing underwriters, if any, and such holders

J-10

may reasonably request in order to permit the intended method of distribution of such securities and make all required filings of such prospectus supplement or such post-effective amendment as soon as practicable after the Company has received such request; provided, however, that the Company shall not be required to take any actions under this Section 2.06(a)(iii) that are not, in the good faith opinion of the Company, in compliance with Applicable Law;

(iv) furnish to each Selling Holder and each underwriter, if any, of the securities being sold by such Selling Holder such number of conformed copies of such registration statement and of each amendment and supplement thereto (in each case including all exhibits), such number of copies of the prospectus contained in such registration statement (including each preliminary prospectus and any summary prospectus) and each free writing prospectus (as defined in Rule 405 of the Securities Act) (a "Free Writing Prospectus") utilized in connection therewith and any other prospectus filed under Rule 424 under the Securities Act, in conformity with the requirements of the Securities Act, and such other documents as such Selling Holder and underwriter, if any, may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities owned by such Selling Holder;

(v) use reasonable best efforts to register or qualify or cooperate with the Selling Holders, the underwriters, if any, and their respective counsel in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable Securities covered by such registration statement under such other securities laws or blue sky laws of such jurisdictions as any Selling Holder and any underwriter of the securities being sold by such Selling Holder shall reasonably request and to keep each such registration or qualification (or exemption therefrom) effective during the period such registration statement is required to be kept effective hereunder, and take any other action which may be reasonably necessary or advisable to enable such Selling Holder and underwriter to consummate the disposition in such jurisdictions of the Registrable Securities owned by such Selling Holder, except that the Company shall not for any such purpose be required to qualify generally to do business as a foreign corporation in any jurisdiction wherein it would not, but for the requirements of this subdivision (v), be obligated to be so qualified, to subject itself to taxation in any such jurisdiction or to file a general consent to service of process in any such jurisdiction;

(vi) use reasonable best efforts to cause such Registrable Securities to be listed on each securities exchange on which the same securities issued by the Company are then listed;

(vii) use reasonable best efforts to cause such Registrable Securities covered by such registration statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to enable the Selling Holder(s) thereof to consummate the disposition of such Registrable Securities;

(viii) use reasonable best efforts to provide and cause to be maintained a transfer agent and registrar for all Registrable Securities covered by such registration statement from and after a date not later than the effective date of such registration statement;

(ix) make, in accordance with customary practice and upon reasonable notice during normal business hours, available for inspection by representatives of the Selling Holders, any underwriters and any counsel or accountant retained by the Selling Holders or underwriters all relevant financial and other records, pertinent corporate documents and properties of the Company and cause appropriate officers, managers, employees, outside counsel and accountants of the Company to supply all information reasonably requested by any such representative, underwriter, counsel or accountant in connection with their due diligence exercise, including through in-person meetings, but subject to the recipients of such information executing customary confidentiality agreements and to customary privilege constraints and so long as such access or request does not unreasonably disrupt the normal operations of the Company and its subsidiaries.

(xii) notify each Selling Holder, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, upon discovery that, or upon the happening of any event as a result of which, the registration statement, the prospectus included in such registration statement or any document incorporated or deemed to be incorporated therein by reference, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to be stated in order to make the statements therein, not misleading, and, at the request of any Selling Holder, as promptly as reasonably practicable prepare and furnish to such Selling Holder a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to be stated in order to make the statements made, in light of the circumstances under which they were made, not misleading;

J-12

Table of Contents

(xiii) make every reasonable effort to obtain the withdrawal of any order suspending the effectiveness of the registration statement and to prevent or obtain the lifting of any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction as any Selling Holder and any underwriter of the securities being sold by such Selling Holder shall reasonably request at the earliest date reasonably practicable;

(xiv) otherwise use reasonable best efforts to comply with all applicable rules and regulations of the Commission, and make available to Selling Holders, as soon as reasonably practicable, an earnings statement covering the period of at least 12 months, but not more than 18 months, beginning with the first day of the Company's first full quarter after the effective date of such registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder;

(xv) cooperate with each seller of Registrable Securities and each underwriter or agent participating in the disposition of such Registrable Securities and their respective counsel in connection with any filings required to be made with the Financial Industry Regulatory Authority, Inc.;

(xvi) prior to the date on which the pricing of the relevant offering is expected to occur, provide a CUSIP number for the Registrable Securities;

(xvii) use its reasonable best efforts to assist Stockholders who made a request of the Company to provide for a third party "market maker" for the Shares; provided, however, that the Company shall not be required to serve as such "market maker"; and

(xviii) have appropriate officers of the Company prepare and make presentations at any "road shows" and before analysts and rating agencies, as the case may be, and otherwise use its reasonable best efforts to cooperate as reasonably requested by the underwriters in the offering, marketing or selling of the Registrable Securities.

(b) Agreements. Without limiting any of the foregoing, the Company agrees to, in connection with registration of any Registrable Securities under this Article II, enter into an underwriting agreement in form, scope and substance as is customary in underwritten offerings including indemnification provisions and procedures substantially to the effect set forth in Section 2.09 hereof with respect to all parties to be indemnified pursuant thereto. In connection with any offering of Registrable Securities registered pursuant to this Agreement, the Company shall (i) furnish to the underwriter, if any (or, if no underwriter, the sellers of such Registrable Securities), unlegended (unless otherwise required by Applicable Law) certificates representing ownership of the Registrable Securities being sold under the registration statement, in such denominations and registered in such names as requested by the lead or co-managing underwriters or sellers, (ii) make available to the Company's transfer agent prior to the effectiveness of such registration statement a supply of such certificates and (iii) instruct any transfer agent and registrar of the Registrable Securities to release any stop transfer order with respect thereto.

(c) Return of Prospectuses. Each Selling Holder agrees that upon receipt of any notice from the Company of the happening of any event of the kind described in clauses (B) through (D) of Section 2.06(a)(xi) or in Section 2.06(a)(xii), such Selling Holder shall forthwith discontinue such Selling Holder's disposition of Registrable Securities pursuant to the applicable registration statement and prospectus relating thereto until such Selling Holder's receipt of the copies of the supplemented or amended prospectus contemplated by Section 2.06(a)(xi) or until it is advised in writing by the Company that the use of the applicable prospectus may be resumed, and has received copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such prospectus and, if so directed by the Company, deliver to the Company, at the Company's expense, all copies, other than permanent file copies, then in such Selling Holder's possession of the

J-13

Table of Contents

prospectus current at the time of receipt of such notice relating to such Registrable Securities. If the Company shall give such notice, any applicable 120 day or two year period during which such registration statement must remain effective pursuant to this Agreement shall be extended by the number of days during the period from the date of giving of a notice regarding the happening of an event of the kind described in Section 2.06(a)(xi) or Section 2.06(a)(xii) to the date when all such Selling Holders shall receive such a supplemented or amended prospectus and such prospectus shall have been filed with the Commission.

(d) Requested Information. Not less than five Business Days before the expected filing date of each registration statement pursuant to this Agreement, the Company shall notify each Selling Holder of the information, documents and instruments from such Selling Holder that the Company or any underwriter reasonably requests in connection with such registration statement, including to a questionnaire, custody agreement, power of attorney, lock-up letter and underwriting agreement (the "Requested Information"). If the Company has not received, on or before the second day before the expected filing date, the Requested Information from such Selling Holder, the Company may file the registration statement without including Registrable Securities of such Selling Holder. The failure to so include in any registration statement the Registrable Securities of a Selling Holder (with regard to that registration statement) shall not in and of itself result in any liability on the part of the Company to such Selling Holder. In the event that, either immediately prior to or subsequent to the effectiveness of any registration statement, any Stockholder shall distribute Registrable Securities to its stockholders, partners or members, such Stockholder shall so advise the Company and provide such information as shall be necessary or advisable to permit an amendment to such registration statement or supplement to any prospectus to provide information with respect to such stockholders, partners or members, in their capacity as selling security holders (it being understood that no such distribution of any Shares may be effectuated following the pricing of an Underwritten Offering that includes such Shares). As soon as reasonably practicable following receipt of such information, the Company shall file an appropriate amendment to such registration statement or supplement to any prospectus reflecting the information so provided.

(e) No Requirement to Participate. Neither the Company nor any Stockholder shall be required to participate in any Public Offering.

(f) Rule 144. The Company covenants that it will use its reasonable best efforts to (i) file in a timely fashion the reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the Commission thereunder (or, if it is not required to file such reports, it will, upon the request of any holder of Registrable Securities, make publicly available other information so long as necessary to permit sales in compliance with Rule 144 under the Securities Act), (ii) furnish to any holder of Registrable Securities, as promptly as reasonably practicable upon request, a written statement by the Company as to its compliance with the reporting requirements of Rule 144 under the Securities Act and of the Exchange Act, and (iii) take such further reasonable action, to the extent required from time to time to enable such holder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 under the Securities Act, as such Rule may be amended from time to time, or any similar rule or regulation hereafter adopted by the Commission.

SECTION 2.07 Registration Expenses. All expenses incident to the Company's performance of, or compliance with, its obligations under this Agreement including (a) all registration and filing fees, all fees and expenses of compliance with securities and blue sky laws (including the reasonable and documented fees and disbursements of counsel for the underwriters in connection with blue sky qualifications of the Registrable Securities pursuant to Section 2.06), (b) all printing and copying expenses (including expenses of printing certificates for the Registrable Securities in a form eligible for deposit with the Depository Trust Company and of printing prospectuses as requested by any holder of Registrable Securities), (c) all messenger and delivery expenses, (d) all fees and expenses of the

Table of Contents

Company's independent certified public accountants and counsel (including, with respect to "comfort" letters and opinions) and (e) all reasonable fees and disbursements of one single primary outside counsel and one outside local counsel for each jurisdiction that Registrable Securities shall be distributed for the holders thereof, which counsels shall be selected by the holders of a majority of the Registrable Securities being sold (collectively, the "Registration Expenses") shall be borne by the Company. The Registration Expenses shall be borne by the Company regardless of whether or not any registration statement is filed or becomes effective. the Company will pay its internal expenses (including all salaries and expenses of its officers and employees performing legal or accounting duties, the expense of any annual audit and the expense of any liability insurance), the expenses and fees for listing the securities to be registered on each securities exchange and included in each established over-the-counter market on which similar securities issued by the Company are then listed or traded and any expenses of the Company incurred in connection with any "road show". Each Selling Holder shall pay its pro rata portion (based on the number of Registrable Securities registered) of all underwriting discounts and commissions and transfer taxes, if any, relating to the sale of such Selling Holder's Registrable Securities pursuant to any registration.

SECTION 2.08 Miscellaneous. The Company may grant demand, piggyback or shelf registration rights to third parties, provided that the terms of such rights are not senior to and do not conflict with the rights granted to the holders of Registrable Securities hereunder without the prior written consent (such consent not to be unreasonably withheld, delayed or conditioned) of the OEP Stockholders.

SECTION 2.09 Indemnification. (a) The Company shall indemnify and hold harmless each Selling Holder and their respective Affiliates, member, partners, directors, officers and employees and each Person, if any, who controls any Selling Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each of their respective representatives as follows:

(i) against any and all losses, liabilities, claims, damages, judgments and reasonable expenses whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement (or any amendment thereto) pursuant to which Registrable Securities were registered under the Securities Act, including all documents incorporated therein by reference, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact contained in any prospectus (or any amendment or supplement thereto) including all documents incorporated therein by reference, or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all losses, liabilities, claims, damages, judgments and reasonable expenses whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, investigation or proceeding by any governmental agency or body, commenced or threatened, or of any other claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, if such settlement is effected with the written consent of the Company; and

(iii) against any and all reasonable expense whatsoever, as incurred (including, subject to Section 2.09(c), fees and disbursements of counsel) incurred in investigating, preparing or defending against any litigation, investigation or proceeding by any governmental agency or body, commenced or threatened, in each case whether or not such Person is a party, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under subparagraph (i) or (ii) above;

J-15

Table of Contents

provided, however, that this indemnity agreement does not apply to any Selling Holder with respect to any loss, liability, claim, damage, judgment or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission (A) made in reliance upon and in conformity with written information furnished to the Company by any Selling Holder expressly for use in a Registration Statement (or any amendment thereto) or any related prospectus (or any amendment or supplement thereto) or (B) if such untrue statement or omission or alleged untrue statement or omission was corrected in an amended or supplemented Registration Statement or prospectus and the Company had furnished copies thereof to the Person asserting such loss, liability, claim, damage, judgment or expense purchased the securities that are the subject thereof prior to the date of sale by such Selling Holder to such Person.

(b) Indemnification by Selling Holders. Each Selling Holder shall severally (but not jointly) indemnify and hold harmless the Company, and each other Selling Holder, and each of their respective Affiliates, members, partners, directors, officers and employees (including each officer of the Company who signed the Registration Statement) and each Person, if any, who controls the Company, or any other Selling Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each of their respective representatives, against any and all losses, liabilities, claims, damages, judgments and expenses described in the indemnity contained in Section 2.09(a) (provided that any settlement of the type described therein is effected with the written consent of such Selling Holder) as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in a Registration Statement (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by such Selling Holder expressly for use in such Registration Statement (or any amendment thereto) or such prospectus (or any amendment or supplement thereto); provided, however, that an indemnifying Selling Holder shall not be required to provide indemnification in any amount in excess of the amount by which (x) the total price at which the Registrable Securities sold by such indemnifying Selling Holder and its Affiliates and distributed to the public were offered to the public exceeds (y) the amount of any damages which such indemnifying Selling Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. The Company shall be entitled, to the extent customary, to receive indemnification and contribution from underwriters, selling brokers, dealer managers and similar securities industry professionals participating in the distribution, to the same extent as provided above with respect to information so furnished in writing by such Persons specifically for inclusion in any prospectus or Registration Statement.

(c) Conduct of Indemnification Proceedings. Each indemnified party or parties shall give reasonably prompt notice to each indemnifying party or parties of any action or proceeding commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party or parties shall not relieve it or them from any liability which it or they may have under this indemnity agreement, except to the extent that the indemnifying party is materially prejudiced by such failure to give notice. If the indemnifying party or parties so elects within a reasonable time after receipt of such notice, the indemnifying party or parties may assume the defense of such action or proceeding at such indemnifying party's or parties' expense with counsel chosen by the indemnifying party or parties and approved by the indemnified party defendant in such action or proceeding, which approval shall not be unreasonably withheld; provided, however, that, if such indemnified party or parties reasonably determine that a conflict of interest exists and that therefore it is advisable for such indemnified party or parties to be represented by separate counsel or that, upon advice of counsel, there may be legal defenses available to it or them which are different from or in addition to those available to the indemnifying party, then the indemnifying party or parties shall not be entitled to assume such defense and the indemnified party or parties shall be entitled to separate counsel (limited in each jurisdiction to one counsel for all indemnified parties under this Agreement) at the indemnifying party's or parties' expense. If any indemnifying party or parties are not so entitled to assume the defense of such action or do not assume such defense, after having received the notice

J-16

Table of Contents

referred to in the first sentence of this paragraph, the indemnifying party or parties will pay the reasonable fees and expenses of counsel for the indemnified party or parties (limited in each jurisdiction to one counsel for all indemnified parties under this Agreement). In such event, however, no indemnifying party or parties will be liable for any settlement effected without the written consent of such indemnifying party or parties (which consent shall not be unreasonably withheld or delayed); provided, however, that if at any time an indemnified party or parties shall have requested an indemnifying party or parties to reimburse the indemnified party or parties for fees and expenses of counsel as contemplated by this paragraph, the indemnifying party or parties shall be liable for any settlement of any proceeding effected without the written consent of such indemnifying party or parties if (x) such settlement is entered into more than 15 business days after receipt by such indemnifying party or parties of the aforesaid request accompanied by supporting documents reasonably satisfactory to the indemnifying party or parties and (y) such indemnifying party or parties shall not have reimbursed the indemnified party or parties in accordance with such request prior to the date of such settlement. If an indemnifying party is entitled to assume, and assumes, the defense of such action or proceeding in accordance with this paragraph, such indemnifying party or parties shall not, except as otherwise provided in this Section 2.09(c), be liable for any fees and expenses of counsel for the indemnified parties incurred thereafter in connection with such action or proceeding.

(d) Contribution. (i) In order to provide for just and equitable contribution in circumstances in which the indemnity agreement provided for in this Section 2.09 is for any reason held to be unenforceable by the indemnified parties although applicable in accordance with its terms in respect of any losses, liabilities, claims, damages, judgments and expenses suffered by an indemnified party referred to therein, each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, liabilities, claims, damages, judgments and expenses in such proportion as is appropriate to reflect the relative fault of the Company, on the one hand, and of the liable Selling Holders (including, in each case, that of their respective officers, directors, employees and agents), on the other, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages, judgments or expenses, as well as any other relevant equitable considerations. The relative fault of the Company, on the one hand, and of the liable Selling Holders (including, in each case, that of their respective officers, directors, employees and agents), on the other, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, on the one hand, or by or on behalf of the Selling Holders, on the other, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, liabilities, claims, damages, judgments and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 2.09(c), any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim.

(ii) The Company and each Selling Holder agree that it would not be just and equitable if contribution pursuant to this Section 2.09(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in sub-paragraph (i) above. Notwithstanding this Section 2.09(d), in the case of distributions to the public, an indemnifying Selling Holder shall not be required to contribute any amount in excess of the amount by which (A) the total price at which the Registrable Securities sold by such indemnifying Selling Holder and its Affiliates and distributed to the public were offered to the public exceeds (B) the amount of any damages which such indemnifying Selling Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

J-17

Table of Contents

(iii) For purposes of this Section, each Person, if any, who controls a Selling Holder within the meaning of Section 15 of the Securities Act shall have the same rights to contribution as such Selling Holder; and each director of the Company, each officer of the Company who signed the Registration Statement, and each Person, if any, who controls the Company within the meaning of Section 15 of the Securities Act, shall have the same rights to contribution as the Company.

$22,500,000 |  | [ , 2017] (the "Issue Date")

Solstice Sapphire Investments, Inc., a Delaware corporation ("Payor"), for value received, promises to pay to each person identified on Schedule I hereto (each, a "Payee") the principal amount set forth opposite its name on Schedule I together with accrued interest thereon, calculated and payable as set forth below (together with any PIK Notes issued pursuant to Section 1.1 below, the "Note"). The principal and interest on this Note is payable in lawful money of the United States of America in immediately available funds at such place in the United States as Payee may from time to time designate in writing to Payor.

This Note is made pursuant to that certain Agreement and Plan of Merger (the "Merger Agreement"), dated May 23, 2017 by and among Sonus Networks Inc., Genband Holdings Company, Genband Inc., Genband II, Inc., the Payor and the other parties thereto, and is the "Promissory Note" referred to therein. Payee is receiving this Note pursuant to the Merger Agreement. All capitalized terms used herein and not defined herein shall have the meanings assigned to such terms in the Merger Agreement.

1. Payment of Principal and Interest

1.1 Calculation and Payment of Interest. Interest on the principal balance of this Note outstanding from time to time until paid in full in cash shall accrue at the rate equal to the Applicable Rate per annum, computed on the basis of a 360-day year, for the actual number of days elapsed, commencing on the date hereof. "Applicable Rate" means, 7.5% on or before the date that is exactly six months after the Issue Date, and after the date that is exactly six months after the Issue Date means 10.0%. Interest shall be payable quarterly in arrears, beginning on the last day of the first calendar quarter following the Issue Date and on the last date of each calendar quarter thereafter (each, an "Interest Payment Date") until the Maturity Date; provided, however, that any amount of cash interest which is not paid on an Interest Payment Date as a result of a Payment Restriction or pursuant to Section 3 hereof shall be made either (i) by the issuance of a promissory note in a principal amount equal to interest accrued but not otherwise paid (by the issuance of a PIK Note or otherwise) on the principal amount hereof through and including such Interest Payment Date and otherwise having such terms and provisions that are the same as the terms and provisions of this Note (each such promissory note a "PIK Note") and Payor shall be deemed to have issued a PIK Note for any such interest regardless of whether Payor shall have actually delivered any such PIK Note or (ii) by increasing the principal amount of this Note by the amount of such cash interest. Payee, by its acceptance hereof, acknowledges (i) that Payor is contractually bound hereunder to pay cash interest only to the extent not prohibited by a Payment Restriction or by Section 3 hereof, (ii) that any cash interest not so paid shall be paid in the form of a PIK Note or by increasing the principal amount of this Note by the amount of such cash interest, and (iii) the failure to pay cash interest as a result of a Payment Restriction or pursuant to Section 3 hereof shall not constitute a default or Event of Default under this Note.

1.2 Payment on Maturity Date. The principal balance of, and any accrued and unpaid interest on, this Note (including, for the avoidance of doubt, the principal balance of and any

K-1

Table of Contents

accrued and unpaid interest on any PIK Note) shall be payable in cash on the third anniversary of the Issue Date the ("Maturity Date").

In the event that this Note is prepaid in its entirety, this Note shall be surrendered to Payor for cancellation as a condition to any such prepayment.

1.4 Payment Only on Business Days; Payments Free and Clear. Any payment hereunder which, but for this Section 1.4, would be payable on a day which is not a Business Day, shall instead be due and payable on the Business Day next following such date for payment. All payments hereunder shall be made free and clear of any deduction, withholding or offset and in immediately available funds, except to the extent otherwise required by applicable law.

K-2

Table of Contents

agents under the Senior Indebtedness Documents (the "Acceleration Notice"), declare the entire principal amount of this Note and the interest accrued thereon to be due and payable upon the earlier of (i) one hundred eighty (180) days after the receipt of the Acceleration Notice by Payor and the agents under the Senior Indebtedness Documents or (ii) an acceleration under any of the Senior Indebtedness Documents, and upon any such declaration the same shall become due and payable at such time. If an Event of Default specified in Section 2(a)(i) shall have occurred and be continuing and no Senior Indebtedness shall then be outstanding, the Majority Payees may, at their option, declare the entire principal balance of this Note and the accrued and unpaid interest thereon to be due and payable upon the date which is five Business Days after the date of delivery by Payee to Payor of a written notice of acceleration, and upon any such declaration the same shall become due and payable at such time.

Annex L

Section 262 of the General Corporation Law of the State of Delaware

(a)
  Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to § 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder's shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word "stockholder" means a holder of record of stock in a corporation; the words "stock" and "share" mean and include what is ordinarily meant by those words; and the words "depository receipt" mean a receipt or other instrument issued by a depository representing an interest in 1 or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository.
(b)
  Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to § 251 (other than a merger effected pursuant to § 251(g) of this title and, subject to paragraph (b)(3) of this section, § 251(h) of this title), § 252, § 254, § 255, § 256, § 257, § 258, § 263 or § 264 of this title:
  (1)
    Provided, however, that, except as expressly provided in § 363(b) of this title, no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of the meeting of stockholders to act upon the agreement of merger or consolidation, were either: (i) listed on a national securities exchange or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in § 251(f) of this title
  (2)
    Notwithstanding paragraph (b)(1) of this section, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to §§ 251, 252, 254, 255, 256, 257, 258, 263 and 264 of this title to accept for such stock anything except:
    a.
      Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof;
    b.
      Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or held of record by more than 2,000 holders;
    c.
      Cash in lieu of fractional shares or fractional depository receipts described in the foregoing paragraphs (b)(2)a. and b. of this section; or
    d.
      Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing paragraphs (b)(2)a., b. and c. of this section.
  (3)
    In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under § 251(h), § 253 or § 267 of this title is not owned by the parent immediately prior to

L-1

Table of Contents

the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation.

(4)
  In the event of an amendment to a corporation's certificate of incorporation contemplated by § 363(a) of this title, appraisal rights shall be available as contemplated by § 363(b) of this title, and the procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as practicable, with the word "amendment" substituted for the words "merger or consolidation," and the word "corporation" substituted for the words "constituent corporation" and/or "surviving or resulting corporation."

(c)
  Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the provisions of this section, including those set forth in subsections (d), (e), and (g) of this section, shall apply as nearly as is practicable.
(d)
  Appraisal rights shall be perfected as follows:
  (1)
    If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for notice of such meeting (or such members who received notice in accordance with § 255(c) of this title) with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) of this section that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section and, if 1 of the constituent corporations is a nonstock corporation, a copy of § 114 of this title. Each stockholder electing to demand the appraisal of such stockholder's shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder's shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or
  (2)
    If the merger or consolidation was approved pursuant to § 228, § 251(h), § 253, or § 267 of this title, then either a constituent corporation before the effective date of the merger or consolidation or the surviving or resulting corporation within 10 days thereafter shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section and, if 1 of the constituent corporations is a nonstock corporation, a copy of § 114 of this title. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice or, in the case of a merger approved pursuant to § 251(h) of this title, within the later of the consummation of the offer contemplated by § 251(h) of this title and 20 days after the date of mailing of such

L-2

Table of Contents

notice, demand in writing from the surviving or resulting corporation the appraisal of such holder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder's shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice or, in the case of a merger approved pursuant to § 251(h) of this title, later than the later of the consummation of the offer contemplated by § 251(h) of this title and 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder's shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given.

(e)
  Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) of this section hereof and who is otherwise entitled to appraisal rights, may commence an appraisal proceeding by filing a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party shall have the right to withdraw such stockholder's demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) of this section hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder's written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) of this section hereof, whichever is later. Notwithstanding subsection (a) of this section, a person who is the beneficial owner of shares of such stock held either in a voting trust or by a nominee on behalf of such person may, in such person's own name, file a petition or request from the corporation the statement described in this subsection.
(f)
  Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting

L-3

Table of Contents

corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation.

(g)
  At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder. If immediately before the merger or consolidation the shares of the class or series of stock of the constituent corporation as to which appraisal rights are available were listed on a national securities exchange, the Court shall dismiss the proceedings as to all holders of such shares who are otherwise entitled to appraisal rights unless (1) the total number of shares entitled to appraisal exceeds 1% of the outstanding shares of the class or series eligible for appraisal, (2) the value of the consideration provided in the merger or consolidation for such total number of shares exceeds $1 million, or (3) the merger was approved pursuant to § 253 or § 267 of this title.
(h)
  After the Court determines the stockholders entitled to an appraisal, the appraisal proceeding shall be conducted in accordance with the rules of the Court of Chancery, including any rules specifically governing appraisal proceedings. Through such proceeding the Court shall determine the fair value of the shares exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. Unless the Court in its discretion determines otherwise for good cause shown, and except as provided in this subsection, interest from the effective date of the merger through the date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the merger and the date of payment of the judgment. At any time before the entry of judgment in the proceedings, the surviving corporation may pay to each stockholder entitled to appraisal an amount in cash, in which case interest shall accrue thereafter as provided herein only upon the sum of (1) the difference, if any, between the amount so paid and the fair value of the shares as determined by the Court, and (2) interest theretofore accrued, unless paid at that time. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, proceed to trial upon the appraisal prior to the final determination of the stockholders entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder's certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section.
(i)
  The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the

L-4

Table of Contents

certificates representing such stock. The Court's decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state.

(j)
  The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney's fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal.
(k)
  From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder's demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just; provided, however that this provision shall not affect the right of any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party to withdraw such stockholder's demand for appraisal and to accept the terms offered upon the merger or consolidation within 60 days after the effective date of the merger or consolidation, as set forth in subsection (e) of this section.
(l)
  The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.

PART II
INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 20. Indemnification of Directors and Officers

Delaware General Corporation Law.

Section 102 of the Delaware General Corporation Law (which we refer to as the DGCL) permits a corporation to eliminate the personal liability of its directors or its stockholders for monetary damages for a breach of fiduciary duty as a director, except where the director breached his or her duty of loyalty, failed to act in good faith, engaged in intentional misconduct or knowingly violated a law, authorized the payment of a dividend or approved a stock repurchase in violation of Delaware corporate law or obtained an improper personal benefit.

Section 145 of the DGCL provides that a corporation has the power to indemnify a director, officer, employee or agent of the corporation and certain other persons serving at the request of the corporation in related capacities against expenses (including attorneys' fees), judgments, fines and amounts paid in settlements actually and reasonably incurred by the person in connection with an action, suit or proceeding to which he or she is or is threatened to be made a party by reason of such position, if such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, in any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful, except that, in the case of actions brought by or in the right of the corporation, indemnification may only be made for expenses and no indemnification shall be made with respect to any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or other adjudicating court determines that, despite the adjudication of liability but in view of all of the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

New Solstice Organizational Documents.

The current certificate of incorporation of Solstice Sapphire Investments, Inc., a Delaware corporation (which we refer to as New Solstice), provides that, to the fullest extent permitted by the DGCL as the same exists or may hereafter be amended, a director of New Solstice to the fullest extent permitted by law shall not be personally liable to New Solstice or its stockholders for monetary damages for breach of fiduciary duty as a director. Further, the New Solstice certificate of incorporation provides that any repeal or modification of the provision relating to such limitation of liability shall not adversely affect any right or protection of a director of the New Solstice existing at the time of, or increase the liability of any director of New Solstice with respect to any acts or omissions of such director occurring prior to, such repeal or modification.

The current New Solstice certificate of incorporation provides that, to the fullest extent permitted by applicable law, New Solstice is authorized to provide indemnification of (and advancement of expenses to) its directors, officers and agents of (and any other persons to which the DGCL permits New Solstice to provide indemnification) through Bylaw provisions, agreements with such agents or other persons, vote of stockholders or disinterested directors or otherwise, in excess of the indemnification and advancement otherwise permitted by Section 145 of the DGCL. Further, the New Solstice certificate of incorporation provides that any amendment, repeal or modification of the provision relating to such indemnification shall not adversely affect any right or protection of any New Solstice director, officer or other agent existing at the time of such amendment, repeal or modification.

Upon consummation of the transactions contemplated by the agreement and plan of merger, dated as of May 23, 2017, among Sonus Networks, Inc., New Solstice, Solstice Sapphire, Inc., Green Sapphire Investments LLC, Green Sapphire LLC, GENBAND Holdings Company, GENBAND Inc. and

II-1

Table of Contents

GENBAND II, Inc. (which we refer to as the merger agreement and which is included as Exhibit 2.1 to this registration statement), New Solstice will amend and restate its certificate of incorporation and its bylaws (in substantially the forms included as Exhibit 3.3 and Exhibit 3.4, respectively, to this registration statement) (which we refer to as the New Solstice charter and New Solstice by-laws, respectively).

The New Solstice charter will provide that no director will be personally liable to New Solstice or its stockholders for monetary damages for any breach of fiduciary duty as a director, notwithstanding any provision of law imposing such liability except for liability (i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or knowing violation of law, (iii) under Section 174 of the DGCL or (iv) for any transaction from which the directors derived an improper personal benefit. Further, the New Solstice charter will provide that no amendment to or repeal of the provisions of the New Solstice charter relating to any such limitation of liability shall apply to or have any effect on the liability or alleged liability of any director for or with respect to any acts or omissions of such director occurring prior to the effective date of such amendment or repeal.

The New Solstice by-laws will provide that New Solstice will indemnify its current and former directors and officers to the fullest extent permitted by applicable law, as the same exists or may hereafter be amended, except that New Solstice will not indemnify any director or officer in connection with a proceeding initiated by such person unless such proceeding was authorized or consented to by the New Solstice board, subject to limited exceptions set forth in the New Solstice by-laws. The right to indemnification includes the right to be paid by New Solstice the expenses (including attorneys' fees) incurred in connection with any action, suit or proceeding, whether civil, criminal, administrative or investigative, in advance of its final disposition or in connection with a proceeding brought to establish or enforce a right to indemnification or advancement of expenses under the New Solstice by-laws, provided that the director or officer delivers an undertaking to repay the advanced amounts if it is ultimately determined that the director or officer is not entitled to indemnification or advancement.

The New Solstice by-laws will provide that any repeal or modification of the indemnification provisions shall not adversely affect any right or protection of any indemnitee in respect of any act or omission occurring prior to the time of such repeal or modification. Additionally, the New Solstice by-laws will provide that the indemnification and expense advancement obligations under the New Solstice by-laws shall not be exclusive of any other right that any person may have or hereafter acquire under any law, the New Solstice certificate of incorporation, the bylaws, agreement, vote of stockholders or disinterested directors or otherwise.

Directors' and Officers' Insurance.

Sonus maintains, and if the transaction contemplated by the merger agreement occur New Solstice will maintain, insurance on behalf of any person who is or was an officer or director against claims or liability asserted against him or her and incurred by him or her in such capacity, or arising out of his or her status as such, whether or not New Solstice would have the power or the obligation to indemnify him or her against such liability under New Solstice's by-laws or the DGCL.

(f) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(g) That prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other Items of the applicable form.

(h) That every prospectus (i) that is filed pursuant to the paragraph immediately preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act of 1933 and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(i) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

(j) To respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

(k) To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
