2.1 Registration.

Such Shelf Registration Statement shall provide for the resale of the Registrable Securities included therein pursuant to any method or combination of methods legally available to, and requested by, the Holders. The Company shall maintain a Shelf Registration Statement, in accordance with the terms of this Agreement, and shall prepare and file with the Commission such amendments, including post-effective amendments, and supplements as may be necessary to keep a Shelf Registration Statement continuously effective, available for use to permit the Holders to sell the Registrable Securities included therein and in compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities outstanding. In the event the Company is not eligible to file a Form S-3, the Company shall file the Shelf Registration Statement on Form S-1. The Company’s obligation under this Section 2.1.1, shall, for the avoidance of doubt, be subject to Section 3.3.

2.1.2 Effective Registration. The Company shall use its commercially reasonable efforts, including by filing an automatic Shelf Registration Statement that becomes effective upon filing with the Commission to the extent that the Company is then a WKSI, to cause such Shelf Registration Statement to become effective by the Commission as soon as reasonably practicable, including by the earlier of (i) ten (10) Business Days after confirmation from the staff of the Commission that such staff will not review, or has no further comments on, such Shelf Registration Statement and (ii) sixty (60) calendar days after the initial filing of the Shelf Registration Statement.

2.1.3 Subsequent Shelf Registration Statement. If any Registration Statement ceases to be effective under the Securities Act for any reason at any time while Registrable Securities are still outstanding, the Company shall, subject to Section 3.3, use its commercially reasonable efforts to as promptly as is reasonably practicable cause such Registration Statement to again become effective under the Securities Act (including using its commercially reasonable efforts to obtain the prompt withdrawal of any order suspending the effectiveness of such Registration Statement), and shall use its commercially reasonable efforts to as promptly as is reasonably practicable amend such Registration Statement in a manner reasonably expected to result in the withdrawal of any order suspending the effectiveness of such Registration Statement or file an additional Registration Statement as a Shelf Registration Statement (a “Subsequent Shelf Registration Statement”) registering the resale of all Registrable Securities from time to time, which Subsequent Shelf Registration Statement shall thereafter be deemed a Shelf Registration Statement for all purposes hereunder and subject to all requirements with respect thereto. If a Subsequent Shelf Registration Statement is filed, the Company shall use its commercially reasonable efforts to (a) cause such Subsequent Shelf Registration Statement to become effective under the Securities Act as promptly as is reasonably practicable after the filing thereof, including by filing an automatic Shelf Registration Statement that becomes effective upon filing with the Commission to the extent that the Company is then a WKSI, and (b) keep such Subsequent Shelf Registration Statement continuously effective, available for use to permit the Holders to sell their Registrable Securities included therein and in compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities. Any such Subsequent Shelf Registration Statement shall be on Form S-3 to the extent that the Company is eligible to use such form. Otherwise, such Subsequent Shelf Registration Statement shall be on Form S-1. The Company’s obligation under this Section 2.1.3, shall, for the avoidance of doubt, be subject to Section 3.3.

2.2 Shelf Underwritten Offering.

2.2.1 Shelf Underwritten Offering. In the event that one or more Selling Holders (the “Offering Holders”) elect to dispose of Registrable Securities totaling five percent (5%) or more (the “Minimum Amount”) of the outstanding Company Common Stock under a Shelf Registration Statement pursuant to an Underwritten Offering, the Company shall, at the request of the Offering Holders, subject to the agreement of the Company on the form of such Underwritten Offering (whether a typical underwritten offering, or an overnight or bought deal), enter into an underwriting agreement in a form as is customary in Underwritten Offerings of securities by the Company with the Managing Underwriter or Managing Underwriters selected pursuant to Section 2.2.3 and shall take all such other reasonable actions as are requested by the Managing Underwriter of such Underwritten Offering and/or the Offering Holders in order to expedite or facilitate the disposition of such Registrable Securities (a “Shelf Underwritten Offering”); provided, however, that the Company shall have no obligation to facilitate more than two Shelf Underwritten Offerings that are initiated by the Holders pursuant to this Section 2.2.1. If any Selling Holder disapproves of the terms of a Shelf Underwritten Offering contemplated by this Section 2.2.1, such Selling Holder may elect to withdraw therefrom by notice to the Company and the Managing Underwriter of such Shelf Underwritten Offering at any time prior to the execution of an underwriting agreement with respect to such offering. Upon delivery of such a notice by all of the Offering Holders or by a number of Selling Holders such that the remaining Registrable Securities subject to such Shelf Underwritten Offering is less than the Minimum Amount, (i) such Shelf Underwritten Offering shall be deemed to be withdrawn, (ii) the Company may, at its option, cease all efforts to conduct such Shelf Underwritten Offering, (iii) the first such withdrawn Shelf Underwritten Offering shall not count against the limitation on Shelf Underwritten Offerings set forth in the first sentence of this Section 2.2.1, and (iv) any subsequent withdrawn Shelf Underwritten Offering shall count against the limitation on Shelf Underwritten Offerings set forth in the first sentence of this Section 2.2.1 unless (a) each Selling Holder shall have paid or reimbursed the Company for its pro rata share of all commercially reasonable and documented fees and expenses incurred by the Company in connection with the withdrawn Shelf Underwritten Offering (based on the number of Registrable Securities each such Selling Holder sought to include in such Shelf Underwritten Offering) or (b) the withdrawal is made a result of the Company’s exercise of its suspension rights under Section 3.3.

2.2.2 Priority on Shelf Underwritten Offerings. If the Managing Underwriter of the Shelf Underwritten Offering shall inform the Company and the Offering Holders in writing of its belief that the number of shares of Company Common Stock requested to be included in such Shelf Underwritten Offering by any other persons having registration rights with respect to such offering, when added to the number of Registrable Securities proposed to be offered by the Offering Holders, would materially adversely affect such offering, then the Company shall include in the applicable Underwritten Offering Filing, to the extent of the total number of Registrable Securities that the Company is so advised can be sold in such Shelf Underwritten Offering without so materially adversely affecting such offering (the “Shelf Underwritten Offering Maximum Number of Shares”), Registrable Securities and other shares of Company Common Stock in the following priority:

(a) First, all Registrable Securities that the Holders requested to be included therein (the “Holder Securities”), and

6

(b) Second, to the extent that the number of Holder Securities is less than the Shelf Underwritten Offering Maximum Number of Shares, the number of shares of Company Common Stock requested to be included by any other persons having registration rights with respect to such offering, pro rata among such other persons based on the number of shares of Company Common Stock each requested to be included.

2.2.3 Managing Underwriter. The Offering Holders holding a majority of the Registrable Securities subject to a Shelf Underwritten Offering shall select one or more nationally prominent firms of investment bankers reasonably acceptable to the Company to act as Managing Underwriter(s) with respect to such Shelf Underwritten Offering. The Holders shall determine the pricing of the Registrable Securities offered pursuant to any Shelf Underwritten Offering and the applicable underwriting discounts and commissions and determine the timing of any such Shelf Underwritten Offering.

2.3 Block Trades. In the event that one or more Holders elect to dispose of Registrable Securities pursuant to a block trade with the assistance of the Company (a “Block Trade”), the Company shall, at the request of such Holders, enter into customary agreements and take all such other customary actions to expedite or facilitate the disposition of such Registrable Securities, including, without limitation, filing any required prospectus supplements, facilitating customary “underwriters’ due diligence” and causing delivery of customary comfort letters, officer’s certificates and legal opinions, as are requested by such Holders or any financial counterparty participating in or facilitating such block trade.

2.4 Piggyback Registration Rights.

2.4.1 Piggyback Underwritten Offering. Subject to Section 2.4.3, if the Company at any time proposes to file an Underwritten Offering Filing for an Underwritten Offering of shares of Company Common Stock for its own account or for the account of any other persons who have or have been granted registration rights (a “Piggyback Underwritten Offering”), it will give written notice of such Piggyback Underwritten Offering to the Holders, which notice shall be held in strict confidence by the Holders and shall include the anticipated filing date of the Underwritten Offering Filing and, if known, the number of shares of Company Common Stock that are proposed to be included in such Piggyback Underwritten Offering, and of such Holders’ rights under this Section 2.4.1. Such notice shall be given promptly (and in any event at least ten (10) Business Days before the filing of the Underwritten Offering Filing or two Business Days before the filing of the Underwritten Offering Filing in connection with a bought or overnight Underwritten Offering); provided, that if the Piggyback Underwritten Offering is a bought or overnight Underwritten Offering and the Managing Underwriter advises the Company in writing that the giving of notice pursuant to this Section 2.4.1 would adversely affect such offering, no such notice shall be required (and the Holders shall have no right to include Registrable Securities in such bought or overnight Underwritten Offering). If such notice is delivered pursuant to this Section 2.4.1, each Holder shall then have four Business Days (or one Business Day in the case of a bought or overnight Underwritten Offering) after the date on which such Holder received notice pursuant to this Section 2.4.1 to request inclusion of Registrable Securities in the Piggyback Underwritten Offering (which request shall specify the maximum number of Registrable Securities intended to be disposed of by such Holder and such other information as is reasonably required to effect the inclusion of such Registrable Securities). If no request for inclusion from a Holder is received within such period, such Holder shall have no further right to participate in such Piggyback Underwritten Offering. Subject to Section 2.4.3, the Company shall use its commercially reasonable efforts to include in the Piggyback Underwritten Offering all Registrable Securities that the Company has been so requested to include by a Holder; provided, however, that if, at any time after giving written notice of a proposed Piggyback Underwritten Offering pursuant to this Section 2.4.1 and prior to the execution of an underwriting agreement with respect thereto, the Company or such other persons who have or have been granted registration rights, as applicable, shall determine for any reason not to proceed with or to delay such Piggyback Underwritten Offering, the Company shall give written notice of such determination to the Holders participating in such Piggyback Underwritten Offering (which such Holders will hold in strict confidence) and (i) in the case of a determination not to proceed, shall be relieved of its obligation to include any Registrable Securities in such Piggyback Underwritten Offering (but not from any obligation of the Company to pay the Registration Expenses in connection therewith), and (ii) in the case of a determination to delay, shall be permitted to delay inclusion of any Registrable Securities for the same period as the delay in including the shares of Company Common Stock to be sold for the Company’s account or for the account of such other persons who have or have been granted registration rights, as applicable. Each Holder shall have the right to withdraw its request for inclusion of its Registrable Securities in any Piggyback Underwritten Offering at any time prior to the execution of an underwriting agreement with respect thereto by giving written notice to the Company of its request to withdraw.

7

2.4.2 Opt-Out Notice. Each Holder may deliver written notice (an “Opt-Out Notice”) to the Company requesting that such Holder not receive notice from the Company of any proposed Underwritten Offering, whether a Piggyback Underwritten Offering, a Shelf Underwritten Offering or otherwise; provided, however, that such Holder may later revoke any such Opt-Out Notice in writing. Following receipt of an Opt-Out Notice from a Holder (unless subsequently revoked), the Company shall not, and shall not be required to, deliver any notice of any proposed Underwritten Offering pursuant to this Agreement, and such Holder shall not be entitled to participate in any such Underwritten Offering.

2.4.3 Priority on Piggyback Underwritten Offerings. If the Managing Underwriter of the Piggyback Underwritten Offering shall inform the Company of its belief that the number of Registrable Securities requested to be included in a Piggyback Underwritten Offering, when added to the number of shares of Company Common Stock proposed to be offered by the Company or such other persons who have or have been granted registration rights (and any other shares of Company Common Stock requested to be included by any other persons having registration rights on parity with the Holders with respect to such offering), would materially adversely affect such offering, then the Company shall include in such Piggyback Underwritten Offering, to the extent of the total number of securities which the Company is so advised can be sold in such offering without so materially adversely affecting such offering (the “Piggyback Underwritten Offering Maximum Number of Shares”), shares of Company Common Stock in the following priority:

(a) First, (i) if the Piggyback Underwritten Offering is for the account of the Company, all shares of Company Common Stock that the Company proposes to include for its own account (the “Company Securities”) or, (ii) if the Piggyback Underwritten Offering is for the account of any other persons who have or have been granted registration rights, all shares of Company Common Stock that such persons propose to include (the “Other Securities”); and

(b) Second, (i) if the Piggyback Underwritten Offering is for the account of the Company, to the extent that the number of Company Securities is less than the Piggyback Underwritten Offering Maximum Number of Shares, the shares of Company Common Stock requested to be included by the Holders and holders of any other shares of Company Common Stock requested to be included by persons having comparable rights to registration with the Holders with respect to such offering, pro rata among the Holders and such other holders based on the number of shares of Company Common Stock each requested to be included and, (ii) if the Piggyback Underwritten Offering is for the account of any other persons who have or have been granted registration rights, to the extent that the number of Other Securities is less than the Piggyback Underwritten Offering Maximum Number of Shares, the shares of Company Common Stock requested to be included by the Holders and holders of any other shares of Company Common Stock requested to be included by persons having rights of registration on parity with the Holders with respect to such offering, pro rata among the Holders and such other holders based on the number of shares of Company Common Stock each requested to be included.

2.5 Participation in Underwritten Offerings.

2.5.1 In connection with any Underwritten Offering contemplated by Section 2.2 or Section 2.4, the underwriting agreement into which the Selling Holders and the Company shall enter into shall contain such representations, covenants, indemnities (subject to Article IV) and other rights and obligations as are customary in Underwritten Offerings of securities by the Company. No Selling Holder shall be required to make any representations or warranties to or agreements with the Company or the underwriters other than representations, warranties or agreements regarding such Selling Holder’s authority to enter into such underwriting agreement and to sell, and its ownership of and lack of liens on, the securities being registered on its behalf, its intended method of distribution and any other representation required by law.

If the continued use of a Registration Statement in respect of any Registration at any time would (a) require the Company to make an Adverse Disclosure or (b) render the Company unable to comply with applicable securities laws, the Company may, upon giving prompt written notice of such action to the Holders (which notice shall not specify the nature of the event giving rise to such suspension or disclose any material nonpublic information of the Company), suspend use of such Registration Statement for the shortest period of time determined in good faith by the Board to be necessary for such purpose, provided, however, that the Company may not suspend a Registration Statement or Prospectus on more than two (2) occasions, for more than sixty (60) consecutive calendar days, or more than one hundred-twenty (120) total calendar days, in each case during any twelve (12)-month period, provided, further, that such periods may be extended to a maximum of ninety (120) consecutive days per occasion for an aggregate of no more than one hundred-eighty (180) total calendar days during any twelve (12)-month period solely to the extent such extension is due to the pendency of a restatement of the Company’s financial statements determined in the good faith judgment of the Board to be necessary and in the best interests of the Company. In the event the Company exercises its rights under the preceding sentence in this Section 3.3, the Holders agree to suspend, immediately upon their receipt of the notices referred to in this Section 3.3, its use of the Registration Statement or Prospectus in connection with any resale or other disposition of Registrable Securities. The Company shall immediately notify the Holders of the expiration of any period during which it has exercised its rights under this Section 3.3; provided, that the Holders hereby (i) acknowledge that such notice referred to in the immediately preceding sentence shall constitute confidential information of the Company and (ii) agree to maintain in strict confidence and not to disclose to any person any information contained in such notice (including, without limitation, the fact that the Company has delivered such notice to the Holders). The Company may only exercise its suspension rights under this Section 3.3 if it exercises similar suspension rights with respect to each other holder of securities that is entitled to registration rights under an agreement with the Company.

11

3.4 Reporting Obligations. As long as the Holders shall own Registrable Securities, the Company, at all times while it shall be a reporting company under the Exchange Act, covenants to use commercially reasonable efforts to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act. The Company further covenants that it shall take such further action as the Holders may reasonably request, all to the extent required from time to time to enable the Holders to resell or otherwise dispose of shares of Registrable Securities held by the Holders without registration under the Securities Act within the limitation of the exemptions provided by Section 4(a)(7) of the Securities Act and Rule 144 promulgated under the Securities Act and other rules and regulations of the Commission that may at any time permit a Holder of Registrable Securities to sell securities of the Company without registration, including providing any customary legal opinions.

3.5 No Conflicts of Rights. The Company represents and warrants that it is not subject to any registration rights that are inconsistent with or that in any way violate the rights granted to the Holders hereby. The Company shall not, prior to the termination of this Agreement, grant any registration rights that conflict with, would prevent the Company from performing, or are inconsistent with, the rights granted to the Holders hereby (which, for the avoidance of doubt, shall include granting priority rights superior to those of the Holders in Section 2.2.2 and Section 2.4.3 hereto).

Article IV
INDEMNIFICATION AND CONTRIBUTION

4.1 Indemnification.

4.1.1 The Company agrees to indemnify, to the extent permitted by law, the Holders of Registrable Securities, their Affiliates and their respective officers, directors, managers, employees, advisors, agents, representatives, members and each person who controls such person (within the meaning of the Securities Act) (collectively, the “Holder Indemnified Persons”) against all losses, claims, damages, liabilities and expenses resulting from any Misstatement or alleged Misstatement, except insofar as the same are caused by or contained or included in any information furnished in writing to the Company by or on behalf of any Holder Indemnified Person specifically for use therein.

4.1.2 In connection with any Registration Statement filed pursuant hereto, the Holders shall promptly furnish (or cause to be furnished) to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with such Registration Statement or any Prospectus (the “Holder Information”) and, to the extent permitted by law, shall indemnify the Company, its Affiliates and their respective officers, directors, managers, employees, advisors, agents, representatives and each person who controls such person (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses resulting from any Misstatement or alleged Misstatement, but only to the extent that the same are made in conformity with information relating to the Holders so furnished in writing to the Company by or on behalf of the Holders specifically for use therein. In no event shall the liability of the Holders hereunder be greater in amount than the net proceeds received by the Holders from the sale of Registrable Securities pursuant to such Registration Statement giving rise to such indemnification obligation.

12

4.1.3 Any person or entity entitled to indemnification herein shall (a) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (b) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim or there may be reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying party, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld, conditioned or delayed). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, not to be unreasonably withheld, conditioned or delayed, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement includes a statement or admission of fault and culpability on the part of such indemnified party or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

4.1.4 The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director, employee, advisor, agent, representative, member or controlling person or entity of such indemnified party and shall survive the transfer of securities. The Company and the Holders also agree to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s or the Holders’ indemnification is unavailable for any reason.

4.1.5 If the indemnification provided under this Section 4.1 is held by a court of competent jurisdiction to be unavailable to an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall to the extent permitted by law contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by a court of law by reference to, among other things, whether the Misstatement or alleged Misstatement relates to information supplied by such indemnifying party or such indemnified party and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, however, that the liability of the Holders under this Section 4.1.5 shall be limited to the amount of the net proceeds received by the Holders in such offering giving rise to such liability. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.1.5 were determined by pro rata allocation or by any other method of allocation, which does not take account the equitable considerations referred to in this Section 4.1.5. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 4.1.5 from any person who was not guilty of such fraudulent misrepresentation.

No single or partial exercise of any rights or remedies under this Agreement by a party shall operate as a waiver or preclude the exercise of any other rights or remedies hereunder or thereunder by such party.

5.8 Term. This Agreement shall terminate, with respect to any Holder, on the date as of which such Holder, together with its Affiliates, ceases to hold any Registrable Securities. The provisions of Article IV shall survive any termination for a period of two (2) years.

15
