Preliminary Copy

[—], 2014

Dear Stockholders:

You are cordially invited to attend a special meeting of the stockholders of NetScout Systems, Inc., or NetScout, to be held on [—], 2015 at [—] local time, at NetScout Systems, Inc., 310 Littleton Road, Westford, Massachusetts to vote on actions associated with a strategic acquisition that your board of directors has determined represents an unprecedented opportunity to strengthen NetScout and position it to deliver enhanced, sustainable shareholder value. A notice of the special meeting and the proxy statement follow.

As previously announced, on October 12, 2014, NetScout entered into a definitive agreement with Danaher Corporation, or Danaher, under which NetScout will acquire Danaher’s Communications Business, comprising Tektronix Communications, Arbor Networks, and certain parts of Fluke Networks, which we refer to as the Communications Business.

We believe the acquisition is highly compelling strategically, operationally and financially, and that it will create shareholder value well in excess of what NetScout could achieve on its own, based on benefits that include:

| • |  | a broader portfolio of best-in-class solutions that will double NetScout’s total addressable market to over $8 billion;

| • |  | acceleration of our plans to enter growth-oriented market sectors such as cyber intelligence and business intelligence analytics;

| • |  | substantially stronger go-to-market capabilities to support a broader, more global and diverse customer base of service provider and enterprise customers; and

| • |  | notable operating synergies arising from our greater scale that will enable us to improve efficiencies across a number of key functional areas, along with the resources necessary to fund continued innovation and key sales, marketing and support programs.

In combination, we believe that these benefits will enable NetScout to sustain strong growth on a substantially larger revenue base, which, in combination with notable operating synergies and prudent investment, will enable us to drive our profitability to new levels.

At the special meeting, you will be asked to approve a proposal to issue shares of NetScout common stock in connection with the transactions necessary to combine the Communications Business with the business of NetScout. You will also be asked to approve a proposal to adjourn or postpone the special meeting, if necessary or appropriate, to solicit additional proxies if there are not sufficient votes at the time of the special meeting to approve the issuance of shares of NetScout common stock in the acquisition. If the proposal to approve the issuance of shares of NetScout common stock is not approved, the proposed acquisition cannot be completed.

After consummation of the transactions described in the proxy statement, approximately 59.5% of NetScout common stock is expected to be held by pre-transaction holders of Danaher common stock and approximately 40.5% of NetScout common stock is expected to be held by pre-transaction NetScout stockholders. After the transactions, NetScout common stock issued will continue to be listed on NASDAQ under NetScout’s current symbol, “NTCT.”

##### Table of Contents

The NetScout board of directors recommends that you vote “FOR” the proposal to issue shares of NetScout common stock to facilitate the completion of the acquisition and “FOR” the proposal to approve adjournments or postponements of the special meeting, if necessary or appropriate, to solicit additional proxies if there are not sufficient votes at the time of the special meeting to approve the issuance of shares of NetScout common stock.

Your proxy is being solicited by the board of directors of NetScout. After careful consideration, our board of directors unanimously approved the definitive agreement and determined that this agreement and the other transactions associated with it are advisable and fair to, and in the best interests of, NetScout and its stockholders.

We urge all NetScout stockholders to read the accompanying proxy statement carefully and in its entirety. In particular, we urge you to read carefully the matters discussed under “Risk Factors” beginning on page 29.

Your vote is very important, regardless of the number of shares you own. We cannot complete the acquisition unless the proposal to issue NetScout shares in the transaction is approved by the affirmative vote of a majority of the outstanding shares of common stock that are voted at the special meeting. Regardless of your plans to attend the special meeting in person, please vote by proxy over the telephone, on the internet or by mail as described in the enclosed proxy materials. If you submit your proxy without indicating how you want to vote, your proxy will be counted as a vote “FOR” each of the proposals presented at the special meeting. If you do not vote by telephone, by using the internet or by mail, or if you do not specifically instruct your bank, broker or other nominee how to vote any shares held for you in “street name,” your shares will not be voted at the special meeting.

On behalf of our Board of Directors, we thank you for your support and appreciate your consideration of this matter. We look forward to reporting the results from the special meeting to you.

Very truly yours,
Anil Singhal
Chairman, President, and Chief Executive Officer

EXPLANATORY NOTE

This proxy statement relates to the special meeting of stockholders of NetScout Systems, Inc. (“NetScout”) to approve the issuance of shares of NetScout common stock, par value $0.001 per share, that will be issued in the two-step merger process whereby (i) RS Merger Sub I, Inc., a Delaware corporation (“Merger Sub”), which is a wholly-owned subsidiary of NetScout Systems, Inc., a Delaware corporation (“NetScout”), will merge with and into Newco, with Newco continuing as the surviving company (the “First Merger”) and (ii) immediately following the First Merger, Newco will merge with and into RS Merger Sub II, LLC, a Delaware limited liability company (“Merger Sub II”), which is a wholly-owned subsidiary of NetScout, with Merger Sub II surviving as a wholly-owned subsidiary of NetScout (the “Second Merger”, and together with the First Merger, the “Mergers”). Prior to the Mergers, Danaher will transfer certain assets and liabilities related to the communications business of Danaher, including Tektronix Communications, Arbor Networks and certain parts of Fluke Networks Enterprise, but excluding Danaher’s data communications cable installation business and its communication service provider (field and test tools systems) business (the “Communications Business”), to Newco or one of its subsidiaries. In exchange therefor, Danaher will receive all of the issued and outstanding Newco common units. Newco is a newly formed, wholly-owned subsidiary of Danaher that was organized specifically for the purpose of effecting the Separation (as defined below). Newco has engaged in no business activities to date and it has no material assets or liabilities of any kind, other than those incident to its formation and those incurred in connection with the Transactions (as defined below). The Newco common units will be immediately converted into shares of NetScout common stock in the First Merger. NetScout has filed this proxy statement that relates to the special meeting of stockholders of NetScout to approve the issuance of shares of NetScout common stock in the First Merger. In addition, NetScout has filed a registration statement on Form S-4 (Registration No. 333-200704) to register the shares of its common stock, which will be issued in the First Merger.

Based on market conditions prior to the closing of the Mergers, Danaher will determine whether the Newco common units will be distributed to Danaher’s stockholders in a spin-off or a split-off. In a spin-off, all Danaher stockholders would receive a pro rata number of Newco common units. In a split-off, Danaher would offer its stockholders the option to exchange their shares of Danaher common stock for Newco common units in an exchange offer. If the exchange offer is undertaken and consummated but the exchange offer is not fully subscribed because fewer than all Newco common units owned by Danaher are exchanged, the remaining Newco common units owned by Danaher would be distributed on a pro rata basis to Danaher stockholders whose shares of Danaher common stock remain outstanding after consummation of the exchange offer. After the distribution of Newco common units in a split-off and/or spin-off, as applicable, Newco common units would immediately be converted into shares of NetScout common stock in the First Merger, resulting in a reduction in Danaher’s outstanding shares.

QUESTIONS AND ANSWERS ABOUT THE TRANSACTIONS AND THE SPECIAL MEETING

The following are some of the questions that NetScout stockholders may have, and answers to those questions. These questions and answers, as well as the following summary, are not meant to be a substitute for the information contained in the remainder of this document, and this information is qualified in its entirety by the more detailed descriptions and explanations contained elsewhere in this document. NetScout urges its stockholders to read this document in its entirety prior to making any decision.

| Q: | Why am I receiving these materials?

| A: | NetScout and Danaher have entered into the Merger Agreement pursuant to which the Communications Business will combine with NetScout’s business. NetScout is holding a special meeting of its stockholders in order to obtain stockholder approval of the issuance of shares of NetScout common stock in the First Merger. NetScout cannot complete the Mergers unless the proposal relating to the issuance of NetScout common stock in the First Merger is approved by the affirmative vote of a majority of the shares of NetScout common stock represented and voting at the special meeting, either in person or by proxy (assuming a quorum exists). The adjournment or postponement of the special meeting, if necessary or appropriate, to solicit additional proxies if there are not sufficient votes at the time of the special meeting to approve the issuance of shares of NetScout common stock in the First Merger must also be approved by the affirmative vote of a majority of the shares of NetScout common stock represented and voting at the special meeting, either in person or by proxy.

This document includes important information about the Transactions and the special meeting of the stockholders of NetScout. NetScout stockholders should read this information carefully and in its entirety. A copy of the Merger Agreement is attached as Annex A to this document. The enclosed proxy materials allow NetScout stockholders to vote their shares without attending the NetScout special meeting. The vote of NetScout stockholders is very important and NetScout encourages its stockholders to vote their proxy as soon as possible. Please follow the instructions set forth on the proxy card (or on the voting instruction form provided by the record holder if shares of NetScout stock are held in the name of a bank, broker or other nominee).

| Q: | Who can vote at the special meeting?

| A: | Only holders of record at the close of business on [—] will be entitled to vote at the special meeting. On this record date, there were [—] shares of common stock outstanding and entitled to vote.

Holder of Record

If, on [—], a NetScout stockholder’s shares were registered directly in that stockholder’s name with NetScout’s transfer agent, Computershare, then that stockholder is a holder of record. As a holder of record, a NetScout Stockholder may vote in person at the meeting or vote by proxy. Whether or not NetScout stockholders plan to attend the meeting, we urge NetScout Stockholders to vote by returning the enclosed proxy card or voting by proxy over the telephone or on the internet as instructed below to ensure their vote is counted.

Beneficial Owner

If, on [—], a NetScout stockholder holds shares of NetScout common stock in “street name” or “beneficial name” (that is, the NetScout stockholder holds its shares through a bank, broker or other nominee), a voting instruction form has been forwarded to that stockholder by its bank, broker or other nominee, or its agent which is considered the holder of record with respect to these shares. As the beneficial owner, a NetScout stockholder has the right to direct its bank, broker or other nominee as

to how to vote its shares by following the instructions in the voting instruction form or by voting via the internet or by telephone, but the scope of its rights depends upon the voting processes of the bank, broker or other nominee. Please carefully follow the voting instructions provided by the bank, broker or other nominee or its respective agent.

| Q: | What is NetScout proposing?

| A: | NetScout is proposing to combine the Communications Business with NetScout’s business. The combination will be effected through a series of Transactions that are described in more detail below and elsewhere in this document. At the consummation of these Transactions:

| • |  | the Communications Business will be owned by Merger Sub II, which will be a wholly-owned subsidiary of NetScout; and

| • |  | approximately 59.5% of NetScout common stock is expected to be held by pre-First Merger holders of Danaher common stock and approximately 40.5% of NetScout common stock is expected to be held by pre-First Merger NetScout stockholders.

In the First Merger, NetScout expects to issue an aggregate number of shares of common stock of NetScout equal to (x) 62.5 million shares of NetScout common stock plus the product of (A) 1.46 multiplied by (B) the number of shares of NetScout common stock issued in any acquisition by NetScout prior to the effective time of the First Merger, divided by (y) the aggregate number of Newco common units issued and outstanding immediately prior to the effective time of the First Merger. Based upon the reported closing sale price of $[—] per share for NetScout common stock on NASDAQ on [—], the total value of the shares expected to be issued by NetScout would have been approximately $[—] billion. The value of the consideration to be paid by NetScout in the First Merger will fluctuate with the market price of NetScout common stock until the Mergers are consummated.

| Q: | What are the “Transactions” referenced above?

| A: | On October 12, 2014, NetScout and Danaher agreed to enter into Transactions to effect the transfer of the Communications Business to NetScout. These Transactions provide for the Separation and the Distribution of the Communications Business and the subsequent mergers of (a) Merger Sub with and into Newco, with Newco surviving as a wholly-owned subsidiary of NetScout and (b) Newco with and into Merger Sub II, with Merger Sub II surviving as a wholly-owned subsidiary of NetScout. In order to effect the Separation, the Distribution and the Mergers, Danaher, Newco, NetScout, Merger Sub and Merger Sub II entered into the Merger Agreement and Danaher, Newco and NetScout entered into the Distribution Agreement. In addition, Danaher, Newco, NetScout and certain of their respective affiliates have entered into, or will enter into, various ancillary agreements in connection with the Transactions. These agreements, which are described in greater detail in this document, govern the relationship among Danaher, Newco, NetScout and their respective affiliates after the Separation, the Distribution and the Mergers.

Immediately after the Distribution and on the closing date of the Mergers, Merger Sub will merge with and into Newco, whereby the separate corporate existence of Merger Sub will cease and Newco will continue as the surviving company and as a wholly-owned subsidiary of NetScout. Afterwards, Newco will merge with and into Merger Sub II, whereby the separate corporate existence of Newco will cease and Merger Sub II will continue as the surviving company and as a wholly-owned subsidiary of NetScout. After the Mergers, NetScout will own and operate the Communications Business through Merger Sub II and will also continue its current businesses. All shares of NetScout common stock, including those issued in the First Merger, will be listed on NASDAQ under NetScout’s current trading symbol “NTCT.”

| Q: | What are NetScout’s reasons for pursuing the Transactions described in this proxy statement?

| A: | The board of directors of NetScout considered the following factors as generally supporting its decision to approve the Merger Agreement and recommend that NetScout stockholders approve the issuance of shares of NetScout common stock in the First Merger:

Advances Strategic Objectives. The acquisition advances NetScout’s strategic objectives of expanding its product portfolio across service assurance and performance analytics, business intelligence and cyber security solutions for communications service providers and large and small enterprises, and government organizations. Consequently, NetScout believes that the acquisition will enhance its ability to create long-term value for its stockholders, including by providing the following benefits:

| • |  | The acquisition enables NetScout to grow to a combined non-GAAP annual revenue base of more than $1.2 billion with an expanded range of complementary products, which is expected to position NetScout to drive strong revenue growth and improved profitability over the long term. Over the long term, NetScout management believes that the combined company will be capable of growing revenue at an approximate compounded annual growth rate of 10 percent.

| • |  | The acquisition increases NetScout’s addressable market and broadens both its service provider and enterprise customer base. The acquisition significantly expands NetScout’s total addressable market to more than $8 billion. International Data Corporation (IDC) estimated that spending on network and application performance management solutions, NetScout’s core market prior to the acquisition, was approximately $5.0 billion in 2013. However, NetScout did not have the requisite offerings to fully address key segments within its core market. The acquisition provides NetScout with new capabilities to fill gaps in its product portfolio and target parts of these markets that were previously not available to NetScout such as radio access network optimization and the low-mid tier of the enterprise network performance management market. Additionally, the acquisition enables NetScout to enter the cyber security and advanced analytics (business intelligence) markets in which global spending was estimated by IDC to be over $3 billion in 2013.

| • |  | The acquisition of the Tektronix Communications business provides NetScout with broader access to the service provider market

| • |  | The acquired portions of the Fluke Networks Enterprise business allows NetScout to expand into the mid-tier and smaller enterprise market.

| • |  | The acquisition of Arbor Networks allows NetScout to immediately enter the cyber intelligence and cyber security market.

| • |  | NetScout will gain complementary, award-winning technologies, capabilities and offerings that can better position it to deliver high-value products and services.

| • |  | NetScout will expand its geographical footprint outside of North America.

| • |  | The combined company is expected to have more than 35% of the workforce composed of research and development personnel.

Cost Synergies. NetScout expects to achieve initial annualized run-rate cost synergies of approximately five percent of the combined cost base, or approximately $45 to $55 million within two years from the consummation of the Transactions as a result of increased size, economies of scale, and elimination of redundancies after the Transactions. NetScout expects to generate additional cost synergies in subsequent years by using common infrastructure platforms, and by eliminating or reducing expenses associated with programs and capabilities already in place as NetScout aligns its go-to-market and related support programs and initiatives. However, the magnitude and timing of such synergies has yet to be determined. NetScout’s initial estimates of cost synergies were based on NetScout’s prior experience in integrating acquired companies and an analysis of the cost base of NetScout and the Danaher Communications businesses. NetScout anticipates that a significant portion of the initial cost

8

##### Table of Contents

savings will result from improved gross margins due to improved purchasing power, rationalization of consulting and support services, and opportunities for the combined company to sell lower cost of goods sold products. The remainder of the initial cost savings will be realized as a result of operating expense reduction from sales force rationalization and product roadmap integration.

Accretive Transaction. NetScout expects the Transactions to be accretive on a non-GAAP basis in the first full year of operations.

Transaction Terms and Other Considerations. The board of directors of NetScout also considered the other facts about the Transactions and combined company, such as the fixed share nature of the merger consideration, that the Merger Agreement and the consideration to be paid by NetScout was the result of extensive arm’s-length negotiation, that the Transaction would not require NetScout to deplete cash resources or incur debt, the opinion, dated October 12, 2014, of RBC Capital Markets, Inc. (“RBC Capital Markets”) to NetScout’s board of directors as to the fairness, from a financial point of view and as of such date, to NetScout of the merger consideration, the modest changes to NetScout’s governance structure and the ability of the board of directors of NetScout, subject to the payment of a termination fee, to withdraw or modify its recommendation to the NetScout stockholders to approve the issuance of the NetScout common stock in the First Merger in certain circumstances.

| Q: | What are the key steps of the Transactions?

| A: | Below is a step-by-step list illustrating the material events relating to the Separation, the Distribution and the Mergers. Each of these events is discussed in more detail elsewhere in this proxy statement.

| 1. | Step #1—Internal Restructuring; The Separation. Prior to the Distribution and the First Merger, Danaher will convey to Newco or one or more subsidiaries of Newco certain assets and liabilities constituting the Communications Business, including certain subsidiaries of Danaher, and will cause any applicable subsidiary of Newco to convey to Danaher or its designated subsidiary (other than Newco or any of Newco’s subsidiaries) its specified excluded assets and excluded liabilities.

| 2. | Step #2—The Distribution—Exchange Offer and/or Spin-Off. On the closing date of the Mergers, Danaher will distribute 100% of the Newco common units to Danaher stockholders either through an exchange offer followed by, in the event the exchange offer is not fully subscribed, a spin-off distribution or in a spin-off distribution not including an exchange offer. Danaher expects for the Distribution to be effected through an exchange offer, but the ultimate structure selected will be based on market conditions. In the exchange offer, Danaher will offer its stockholders the option to exchange all or a portion of their shares of Danaher common stock for Newco common units. In the event the exchange offer is not fully subscribed, Danaher will distribute the remaining Newco common units owned by Danaher on a pro rata basis to Danaher stockholders whose shares of Danaher common stock remain outstanding after consummation of the exchange offer.

| 3. | Step #3—The Mergers. In the First Merger, Merger Sub will be merged with and into Newco, with Newco surviving as a wholly-owned subsidiary of NetScout. Immediately thereafter, in the Second Merger, Newco will be merged with and into Merger Sub II, with Merger Sub II surviving as a wholly-owned subsidiary of NetScout. In the First Merger, each outstanding Newco common unit (except Newco common units held by Danaher, Newco, NetScout or Merger Sub) will be converted into the right to receive a number of shares of NetScout common stock equal to (x) 62.5 million shares of NetScout common stock plus the product of (A) 1.46 multiplied by (B) the number of shares of NetScout common stock issued in any acquisition after the date of the Merger Agreement and prior to the effective time of the First Merger, divided by (y) the aggregate number of Newco common units issued and outstanding as of immediately prior to the effective time of the First Merger.

| Q: | What are the material U.S. federal income tax consequences to NetScout and NetScout’s stockholders resulting from the Transactions?

| A: | NetScout will not recognize any gain or loss for U.S. federal income tax purposes as a result of the Mergers. Because NetScout stockholders will not participate in the Distribution or the Mergers, NetScout stockholders will generally not recognize gain or loss upon either the Distribution (including the exchange offer) or the Mergers. NetScout stockholders should consult their own tax advisor for a full understanding of the tax consequences to them of the Distribution and the Mergers. The material U.S. federal income tax consequences of the Distribution and the Mergers are described in more detail in the section of the document entitled “The Transactions—Material U.S. Federal Income Tax Consequences of the Distribution and the Mergers.”

| Q: | What will NetScout stockholders receive in the Mergers?

| A: | NetScout stockholders will not directly receive any consideration in the Mergers. All shares of NetScout common stock issued and outstanding immediately before the Mergers will remain issued and outstanding after consummation of the Mergers. Immediately after the Mergers, NetScout stockholders will continue to own shares in NetScout, which will include the Communications Business.

| Q: | What is the estimated total value of the consideration to be paid by NetScout in the Transactions?

| A: | In the Mergers, NetScout expects to issue approximately 62.5 million shares of NetScout common stock, assuming no adjustment pursuant to the Merger Agreement. Based upon the reported closing sale price of $[—] per share for NetScout common stock on NASDAQ on [—], the total value of the shares expected to be issued by NetScout would have been approximately $[—] billion. The value of the consideration to be paid by NetScout in the Mergers will fluctuate with the market price of NetScout common stock until the Mergers are consummated.

| Q: | What are the principal adverse consequences of the Transactions to NetScout stockholders?

| A: | Following the consummation of the Transactions, NetScout stockholders will participate in a company that holds the Communications Business, but their percentage interest in this company will be diluted. Immediately after the consummation of the Mergers, pre-First Merger NetScout stockholders are expected to own approximately 40.5% of NetScout common stock. Under limited circumstances described in the section of this document entitled “The Merger Agreement—Merger Consideration,” pre-First Merger NetScout stockholders could own less than approximately 40.5% of NetScout common stock following the consummation of the Mergers and under such circumstances, there is no minimum percentage of NetScout common stock that pre-First Merger NetScout stockholders may own. Therefore, the voting power represented by the shares held by pre-First Merger NetScout stockholders will be lower immediately following the Mergers than immediately prior to the First Merger. In addition, in the event that the Distribution is structured as an exchange offer, Danaher stockholders that participate in the exchange offer will be exchanging their shares of Danaher common stock for Newco common units at a discount to the per-share value of NetScout common stock. The existence of a discount, along with the issuance of shares of NetScout common stock pursuant to the First Merger, may negatively affect the market price of NetScout common stock. NetScout also expects to incur significant one-time costs in connection with the Transactions, including advisory, legal, accounting and other professional fees related to the Transactions, transition and integration expenses, such as consulting professionals’ fees, information technology implementation costs and relocation costs, that NetScout management believes are necessary to realize anticipated annualized cost synergies. The incurrence of these costs may have an adverse impact on NetScout’s liquidity or operating results in the periods in which they are incurred. Finally, NetScout will be required to devote

10

##### Table of Contents

| a significant amount of time and attention to the process of integrating the operations of NetScout and the Communications Business. If NetScout is not able to effectively manage the process, NetScout’s business could suffer and its stock price may decline. In addition, the market price of NetScout common stock could decline as a result of sales of a large number of shares of NetScout common stock in the market after the consummation of the Transactions or even the perception that these sales could occur. See “Risk Factors” for a further discussion of the material risks associated with the Transactions.

| Q: | What is NetScout’s dividend policy?

| A: | NetScout currently intends to retain its future earnings, if any, to finance the development and expansion of its business and is limited in its ability to pay cash dividends under the terms of its current credit facility. Therefore, NetScout does not intend to pay cash dividends on its common stock for the foreseeable future. Any future determination to pay dividends will be at the discretion of NetScout’s board of directors and will depend on NetScout’s financial condition, results of operations and capital requirements, restrictions contained in any financing instruments and such other factors as the NetScout board of directors deems relevant.

| Q: | What will Danaher stockholders receive in the Transactions?

| A: | If the Distribution is structured as an exchange offer, Danaher will offer to Danaher stockholders the right to exchange all or a portion of their shares of Danaher common stock for Newco common units. In the event the exchange offer is not fully subscribed, Danaher will distribute in the spin-off the remaining Newco common units owned by Danaher on a pro rata basis to Danaher stockholders whose shares of Danaher common stock remain outstanding after the consummation of the exchange offer. If the Distribution is structured as a spin-off not including an exchange offer, Danaher will distribute in the spin-off the Newco common units owned by Danaher on a pro rata basis to Danaher stockholders. In the First Merger, the Newco common units will be converted into the right to receive NetScout common stock. Thus, each Danaher stockholder will ultimately receive shares of NetScout common stock in the Distribution and the First Merger. Danaher stockholders will not be required to pay for the Newco common units distributed in the spin-off or the shares of NetScout common stock issued in the First Merger. If the Distribution is structured as an exchange offer, Danaher stockholders will receive cash from the exchange offer agent in lieu of any fractional shares of NetScout common stock to which such stockholders would otherwise be entitled. All shares of NetScout common stock issued in the First Merger will be issued in book entry form. Calculated based on the number of outstanding shares and the closing price on NASDAQ of NetScout common stock as of [—], 2015, the shares of NetScout common stock that NetScout expects to issue to Danaher stockholders as a result of the Transactions would have had a market value of approximately $[—] billion in the aggregate (the actual value will not be known until the closing date of the Mergers). For more information, see “The Transactions—The Separation and Distribution,” “The Transactions—The Mergers,” and “The Transactions—Calculation of the Merger Consideration.”

| Q: | Are there any conditions to the consummation of the Transactions?

| A: | Yes. Consummation of the Transactions is subject to a number of conditions, including:

| • |  | the approval of NetScout’s stockholders of the issuance of shares of NetScout common stock in the First Merger;

| • |  | the receipt by Danaher of the IRS Ruling (unless Danaher has not obtained the IRS Ruling by June 30, 2015, in which case the condition will be considered waived);

| • |  | the receipt by Danaher of the Tax Opinion;

11

##### Table of Contents

| • |  | the completion of the various transaction steps contemplated by the Merger Agreement and the Distribution Agreement, including the Separation and the Distribution;

| • |  | clearance of the Mergers under applicable antitrust or competition laws in the United States;

| • |  | the absence of any material adverse effect (as this term is described in the section of this document entitled “The Merger Agreement—Representations and Warranties”) on the Communications Business; and

| • |  | other customary conditions.

If NetScout waives the satisfaction of a material condition to the consummation of the Transactions, NetScout will evaluate the appropriate facts and circumstances at that time and resolicit stockholder approval of the issuance of shares of NetScout common stock in the First Merger if required to do so by law.

This proxy statement describes these conditions in more detail under “The Merger Agreement—Conditions to the Merger.”

| Q: | When will the Transactions be completed?

| A: | NetScout and Danaher are working to complete the Mergers as quickly as possible after satisfaction of the closing conditions, including receipt of applicable regulatory approvals and receipt of NetScout stockholder approval. In addition, other important conditions to the closing of the Separation and the Mergers exist, including, among other things, the completion of the internal restructuring necessary to separate Danaher’s communications assets and liabilities from Danaher’s other business, the receipt of the IRS ruling unless Danaher has not obtained the IRS Ruling by June 30, 2015, in which case the condition will be considered waived, and the receipt of the Tax Opinion. It is possible that factors outside NetScout’s and Danaher’s control could require Danaher to complete the Separation and the Distribution and NetScout and Danaher to complete the Mergers at a later time or not complete them at all. For a discussion of the conditions to the Separation and the Mergers, see “The Transactions—Regulatory Approvals” beginning on page 121, “The Merger Agreement—Conditions to the Merger” beginning on page 137, and “The Distribution Agreement—Conditions to the Separation” beginning on page 146.

| Q: | Are there risks associated with the Transactions?

| A: | Yes. The material risks and uncertainties associated with the Transactions are discussed in the section entitled “Risk Factors” beginning on page 29 and the section entitled “Cautionary Statement Concerning Forward-Looking Statements” beginning on page 35. Those risks include, among others, the possibility that NetScout may fail to realize the anticipated benefits of the Mergers, the uncertainty that NetScout will be able to integrate the Communications Business successfully, the possibility that NetScout may be unable to provide benefits and services or access to equivalent financial strength and resources to the Communications Business that historically have been provided by Danaher, and the substantial dilution to the ownership interest of current NetScout stockholders following the consummation of the Mergers.

| Q: | Will there be any change to the board of directors or the executive officers of NetScout after the Transactions?

| A: | Yes. Those directors of NetScout serving on its board of directors immediately before the effective time of the First Merger are expected to continue to serve as directors of NetScout immediately following the closing of the Mergers. In addition, as of immediately following the effective time of the First Merger, NetScout will increase the size of its board of directors by one member, and one

12

##### Table of Contents

| individual selected by Danaher (which individual is currently anticipated by NetScout and Danaher to be James A. Lico, Danaher’s Executive Vice President) will be appointed to fill the vacancy and will, subject to the fiduciary duties of NetScout’s board of directors, be nominated for re-election at the expiration of such director’s initial term. However, if Danaher’s designated director: (i) is unwilling or unable to serve at the effective time of the First Merger; (ii) is unwilling or unable to serve when such new term starts; or (iii) is not nominated to serve such new term, then Danaher will designate a replacement, acceptable to NetScout in its sole discretion, for such director before the effective time of the First Merger or the start of such new term, as applicable.

| Q: | What stockholder approvals are needed in connection with the Transactions?

| A: | NetScout cannot complete the Transactions unless the proposal relating to the issuance of shares of NetScout common stock in the First Merger is approved by the affirmative vote of a majority of the shares of NetScout common stock represented and voting at the special meeting, either in person or by proxy (assuming a quorum is present). NetScout intends to hold its stockholder meeting as promptly as possible. No vote of Danaher stockholders is required or being sought in connection with the Transactions.

| Q: | Have any NetScout stockholders already agreed to vote for the issuance of shares of NetScout common stock in the First Merger?

| A: | Anil K. Singhal, NetScout’s Chief Executive Officer, has agreed with Danaher to vote the shares of NetScout common stock that he owns, representing approximately 5.5% of the outstanding shares of NetScout common stock as of October 10, 2014, in favor of the issuance of shares of NetScout common stock. In addition, Danaher intends to vote the shares of NetScout common stock that Danaher owns, representing approximately 2.9% of the outstanding shares of NetScout common stock as of October 10, 2014, in favor of the issuance of shares of NetScout common stock in the First Merger.

| Q: | Do Danaher stockholders have to vote to approve the Transactions?

| A: | No.

| Q: | How does the NetScout board of directors recommend stockholders vote?

| A: | The NetScout board of directors recommends that the stockholders of NetScout vote “FOR” approval of the issuance of shares of NetScout common stock in the First Merger and, if necessary or appropriate, “FOR” the adjournment or postponement of the special meeting to solicit additional proxies if there are not sufficient votes at the time of the special meeting to approve the issuance of shares of NetScout common stock in the First Merger.

| Q: | How can NetScout stockholders cast their vote?

| A: | The procedures for voting are fairly simple:

Holder of Record

NetScout holders of record may vote in person at the special meeting, vote by proxy over the telephone, vote by proxy through the internet, or vote by proxy by mail using the enclosed proxy card. Whether or not NetScout stockholders plan to attend the meeting, we urge each NetScout stockholder to vote by proxy to ensure its vote is counted. A NetScout stockholder may still attend the meeting in person even if it has already voted by proxy.

| • |  | To vote in person, a NetScout stockholder should come to the special meeting and we will give it ballot when it arrives.

13

##### Table of Contents

| • |  | To vote using the proxy card, simply complete, sign and date the enclosed proxy card and return it promptly by mail in the envelope provided. If a NetScout stockholder returns a signed proxy card to us before the special meeting, we will vote that NetScout stockholder’s shares as directed.

| • |  | To vote over the telephone, dial the toll-free number specified on the enclosed proxy card using a touch-tone phone and follow the recorded instructions. NetScout stockholders will be asked to provide the company number and control number from the proxy card. Telephone votes must be received by 11:59 p.m. Eastern Time on [—] to be counted.

| • |  | To vote through the internet, go to the website specified on the enclosed proxy card to complete an electronic proxy card. NetScout stockholders will be asked to provide the company number and control number from the proxy card. Internet votes must be received by 11:59 p.m. Eastern time on [—] to be counted.

Beneficial Owner

If a NetScout stockholder is a beneficial owner of shares registered in the name of a bank, broker or other nominee, that NetScout stockholder should have received a notice containing voting instructions from that organization rather than from NetScout. A NetScout stockholder should simply follow the voting instructions to ensure that its vote is counted. Alternatively, a NetScout stockholder may vote by telephone or over the internet as instructed by its bank, broker or other nominee. To vote in person at the special meeting, a NetScout stockholder must obtain a valid proxy from its bank, broker or other nominee. A NetScout stockholder should follow the instructions from its bank, broker or other nominee included with these proxy materials, or contact its bank, broker or other nominee to request a proxy form.

| Q: | How is a quorum determined?

| A: | A quorum of stockholders is necessary to conduct any business at the special meeting. A quorum will be present if a majority of the outstanding shares of our common stock entitled to vote at the special meeting are present at the meeting in person or represented by proxy. On the Record Date, there were [—] shares outstanding and entitled to vote.

To determine a quorum, NetScout includes abstentions and broker non-votes. Broker non-votes occur when a beneficial owner does not give instructions to the broker, bank or other nominee as to how to vote on matters deemed “non-routine.” A NetScout stockholder’s shares will be counted towards the quorum only if such stockholder submits a valid proxy or one is submitted on such stockholder’s behalf by such stockholder’s bank, broker or other nominee or if such NetScout stockholder votes in person at the meeting. If there is no quorum, the meeting may adjourn to another date.

| Q: | What if a NetScout stockholder does not vote on the issuance of shares of NetScout common stock in the First Merger?

| A: | The outcome depends on how the NetScout common stock is held and whether any vote is cast or not:

Holder of Record

| • |  | if a NetScout stockholder submits a proxy to NetScout but the proxy does not indicate how it should be voted on the proposals, the proxy will be counted as a vote “FOR” the proposals;

| • |  | if a NetScout stockholder submits a proxy to NetScout and the proxy indicates that the stockholder abstains from voting, it will have the same effect as a vote against the proposals;

| • |  | if a NetScout stockholder fails to submit a proxy to NetScout, it will have the same effect as a vote against the proposals and that stockholder’s shares will not count towards the required quorum;

##### Table of Contents

Beneficial Owner

| • |  | if a NetScout stockholder does not instruct its bank, broker or other nominee as to how to vote its shares on the proposal to approve the issuance of shares of NetScout common stock in the First Merger, the bank, broker or other nominee may not vote such shares on this proposal because it is a “non-routine matter,” and the resulting broker non-vote will have no effect on this proposal; and

| • |  | if a NetScout stockholder does not instruct its bank, broker or other nominee as to how to vote its shares on the proposal to adjourn or postpone the special meeting, if necessary or appropriate, to solicit additional proxies if there are not sufficient votes at the time of the special meeting to approve the issuance of shares of NetScout common stock in the First Merger, the bank, broker or other nominee may not vote such shares on this proposal because it is a “non-routine matter” and the resulting broker non-vote will have no effect on this proposal.

| Q: | If a NetScout stockholder is not going to attend the special meeting, should that stockholder return its proxy card or otherwise vote its shares?

| A: | Yes. Returning the proxy card by mail, voting by calling the toll-free number shown on the proxy card or voting instruction form, as applicable, or logging on to the website specified on the proxy card or voting instruction form, as applicable, ensures that the shares will be represented and voted at the special meeting, even if a NetScout stockholder will be unable to or does not attend.

| Q: | If a NetScout stockholder’s shares are held in “street name” through its bank, broker or other nominee, will that bank, broker or other nominee vote those shares?

| A: | Banks, brokers or other nominees will vote shares of a NetScout stockholder with respect to the proposals at the special meeting only if the NetScout stockholder instructs its bank, broker or other nominee how to vote. A NetScout stockholder should follow the directions provided by its bank, broker or other nominee regarding how to instruct its bank, broker or other nominee to vote its shares. If a NetScout stockholder does not provide its bank, broker or other nominee with instructions, that bank, broker or other nominee will not be authorized to vote with respect to the proposal to approve the issuance of shares of NetScout common stock in the First Merger or with respect to the proposal to adjourn or postpone the special meeting, if necessary or appropriate, to solicit additional proxies if there are not sufficient votes at the time of the special meeting to approve the issuance of NetScout common stock in the First Merger.

Shares registered in the name of a bank, broker or other nominee may be voted in person at the special meeting by contacting the bank, broker or other nominee to request a letter confirming its beneficial ownership of the shares and that the bank, broker or other nominee will not vote the shares at the special meeting, and bringing that letter to the special meeting.

| Q: | Can a NetScout stockholder change its vote after submitting its proxy?

| A: | Yes. If a holder of record of NetScout common stock has properly completed and submitted its proxy card, the NetScout stockholder can change its vote in any of the following ways:

| • |  | by sending a signed notice of revocation to the Secretary of NetScout that is received prior to the special meeting stating that the NetScout stockholder revokes its proxy;

| • |  | by properly completing a new proxy card bearing a later date and properly submitting it so that it is received prior to the special meeting;

| • |  | by logging onto the internet website specified on the proxy card in the same manner a stockholder would to submit its proxy electronically or by calling the toll-free number specified on the proxy card prior to the special meeting, in each case if the NetScout stockholder is eligible to do so and following the instructions on the proxy card; or

| • |  | by attending the special meeting and voting in person.

15

##### Table of Contents

Simply attending the special meeting will not revoke a proxy. In the event of multiple online or telephone votes by a stockholder, each vote will supersede the previous vote and the last vote cast will be deemed to be the final vote of the stockholder unless such vote is revoked in person at the special meeting.

If a NetScout stockholder holds shares in “street name” through its bank, broker or other nominee, and has directed such person to vote its shares, it should instruct such person to change its vote, or if in the alternative a NetScout stockholder wishes to vote in person at the special meeting, it must bring to the special meeting a letter from the bank, broker or other nominee confirming its beneficial ownership of the shares and that the bank, broker or other nominee is not voting the shares at the special meeting.

| Q: | What should NetScout stockholders do now?

| A: | After carefully reading and considering the information contained in this document, NetScout stockholders should vote their shares as soon as possible so that their shares will be represented and voted at the NetScout special meeting. NetScout stockholders should follow the instructions set forth on the enclosed proxy card (or on the voting instruction form provided by the record holder if their shares are held in the name of a bank, broker or other nominee). The NetScout board of directors recommends that the stockholders of NetScout vote “FOR” approval of the issuance of shares of NetScout common stock in the First Merger, and, if necessary or appropriate, “FOR” the adjournment or postponement of the special meeting to solicit additional proxies if there are not sufficient votes at the time of the special meeting to approve the issuance of shares of NetScout common stock in the First Merger.

| Q: | Can NetScout stockholders dissent and require appraisal of their shares?

| A: | No.

| Q: | Will the instruments that govern the rights of NetScout stockholders with respect to their shares of NetScout common stock after the Transactions be different from those that govern the rights of current NetScout stockholders?

| A: | No. The rights of NetScout stockholders with respect to their shares of NetScout common stock after the consummation of the Transactions will continue to be governed by federal and state laws and NetScout’s governing documents, including:

| • |  | the corporate law of the State of Delaware, including the Delaware General Corporation Law (the “DGCL”);

| • |  | the Third Amended and Restated Certificate of Incorporation of NetScout Systems, Inc. (the “NetScout Charter”); and

| • |  | the Amended and Restated Bylaws of NetScout Systems, Inc. (the “NetScout Bylaws”).

Potomac Holding LLC, a Delaware limited liability company referred to in this document as Newco, is a newly formed, direct wholly-owned subsidiary of Danaher that was organized specifically for the purpose of effecting the Separation. Newco has engaged in no business activities to date and it has no material assets or liabilities of any kind, other than those incident to its formation and those incurred in connection with the Transactions.

Newco is a holding company. In the Transactions, Danaher will transfer the assets and liabilities related to the Communications Business, including certain subsidiaries of Danaher, to Newco or one of its subsidiaries. In exchange therefor, Danaher will receive all the issued and outstanding Newco common units. The Communications Business is the communications group business of Danaher conducted under the brands Tektronix Communications, Fluke Networks and Arbor Networks, and including Newco and its subsidiaries; provided, however, that the Communications Business excludes Danaher’s data communications cable installation business and its communication service provider (field and test tools systems) business.

The Transactions

On October 12, 2014, NetScout and Danaher agreed to enter into Transactions to effect the transfer of the Communications Business to NetScout. These Transactions provide for the Separation and the Distribution of the Communications Business and the subsequent mergers of (a) Merger Sub with and into Newco, with Newco surviving as a wholly-owned subsidiary of NetScout and (b) Newco with and into Merger Sub II, with Merger Sub II surviving as a wholly-owned subsidiary of NetScout. In order to effect the Separation, the Distribution and the Mergers, Danaher, Newco, NetScout, Merger Sub and Merger Sub II entered into the Merger Agreement and Danaher, Newco and NetScout entered into the Distribution Agreement. In addition, Danaher, Newco, NetScout and certain of their respective affiliates have entered into, or will enter into, various ancillary agreements in connection with the Transactions. These agreements, which are described in greater detail in this document, govern the relationship among Danaher, Newco, NetScout and their respective affiliates after the Separation, the Distribution and the Mergers.

##### Table of Contents

Immediately after the Distribution and on the closing date of the Mergers, Merger Sub will merge with and into Newco, whereby the separate corporate existence of Merger Sub will cease and Newco will continue as the surviving company and as a wholly-owned subsidiary of NetScout. Afterwards, Newco will merge with and into Merger Sub II, whereby the separate corporate existence of Newco will cease and Merger Sub II will continue as the surviving company and as a wholly-owned subsidiary of NetScout. After the Mergers, NetScout will own and operate the Communications Business through Merger Sub II and will also continue its current businesses. All shares of NetScout common stock, including those issued in the First Merger, will be listed on NASDAQ under NetScout’s current trading symbol “NTCT.”

Transaction Timeline

Below is a step-by-step list illustrating the material events relating to the Separation, the Distribution and the Mergers. Each of these events is discussed in more detail elsewhere in this document.

Step #1—Internal Restructuring; The Separation. Prior to the Distribution and the First Merger, Danaher will convey to Newco or one or more subsidiaries of Newco certain assets and liabilities constituting the Communications Business, including certain subsidiaries of Danaher, and will cause any applicable subsidiary of Newco to convey to Danaher or its designated subsidiary (other than Newco or any of Newco’s subsidiaries) its specified excluded assets and excluded liabilities.

Step #2—The Distribution—Exchange Offer and/or Spin-Off. On the closing date of the Mergers, Danaher will distribute 100% of the Newco common units to Danaher stockholders either through an exchange offer followed by, in the event the exchange offer is not fully subscribed, a spin-off distribution or in a spin-off distribution not including an exchange offer. Danaher expects for the Distribution to be effected through an exchange offer, but the ultimate structure selected will be based on market conditions. In the exchange offer, Danaher will offer its stockholders the option to exchange all or a portion of their shares of Danaher common stock for Newco common units. In the event the exchange offer is not fully subscribed, Danaher will distribute the remaining Newco common units owned by Danaher on a pro rata basis to Danaher stockholders whose shares of Danaher common stock remain outstanding after consummation of the exchange offer.

Step #3—The Mergers. In the First Merger, Merger Sub will be merged with and into Newco, with Newco surviving as a wholly-owned subsidiary of NetScout. Immediately thereafter, in the Second Merger, Newco will be merged with and into Merger Sub II, with Merger Sub II surviving as a wholly-owned subsidiary of NetScout. In the First Merger, each outstanding Newco common unit (except Newco common units held by Danaher, Newco, NetScout or Merger Sub) will be converted into the right to receive a number of shares of NetScout common stock equal to (x) 62.5 million shares of NetScout common stock plus the product of (A) 1.46 multiplied by (B) the number of shares of NetScout common stock issued in any acquisition after the date of the Merger Agreement and prior to the effective time of the First Merger, divided by (y) the aggregate number of Newco common units issued and outstanding as of immediately prior to the effective time of the First Merger.

##### Table of Contents

The Separation and the Distribution

Prior to the First Merger, pursuant to the terms of the Distribution Agreement, Danaher will convey to Newco or one or more subsidiaries of Newco certain assets and liabilities constituting the Communications Business, and will cause any applicable subsidiary of Newco to convey to Danaher or its designated subsidiary (other than Newco or any of Newco’s subsidiaries) certain excluded assets and excluded liabilities, in order to separate and consolidate the Communications Business under Newco. Immediately thereafter, Danaher will contribute all the equity interests in each subsidiary of Newco to Newco in exchange for a number of common units representing limited liability company interests in Newco, referred to herein as the Newco common units.

22

##### Table of Contents

On the closing date of the Mergers, Danaher will distribute 100% of the Newco common units to Danaher stockholders through either an exchange offer followed by, in the event the exchange offer is not fully subscribed, a spin-off distribution or in a spin-off distribution not including an exchange offer. In the case of an exchange offer, Danaher will offer its stockholders the option to exchange all or a portion of their shares of Danaher common stock for Newco common units. In the event the exchange offer is not fully subscribed, Danaher will distribute the remaining Newco common units owned by Danaher on a pro rata basis to Danaher stockholders whose shares of Danaher common stock remain outstanding after consummation of the exchange offer. If the Distribution is structured as a spin-off not including an exchange offer, Danaher will distribute in the spin-off the Newco common units owned by Danaher on a pro rata basis to Danaher stockholders.

An agent appointed by Danaher will hold, for the account of the relevant Danaher stockholders, the global certificate(s) representing all of the outstanding Newco common units pending the consummation of the First Merger. Newco common units will not be traded during this period.

The Mergers; Merger Consideration

Under the Merger Agreement and in accordance with the DGCL and the DLLCA, at the effective time of the First Merger, Merger Sub will merge with and into Newco. As a result of the First Merger, the separate corporate existence of Merger Sub will terminate and Newco will continue as the surviving company and as a wholly-owned subsidiary of NetScout and will succeed to and assume all the rights, powers and privileges and be subject to all of the obligations of Merger Sub in accordance with the DGCL and the DLLCA. The certificate of formation and the limited liability company operating agreement of Newco in effect immediately prior to the First Merger will be amended and restated in their entirety following the consummation of the First Merger. Immediately following the First Merger, Newco will merge with and into Merger Sub II. As a result of the Second Merger, the separate corporate existence of Newco will terminate and Merger Sub II will continue as the surviving company and as a wholly-owned subsidiary of NetScout and will succeed to and assume all the rights, powers and privileges and be subject to all of the obligations of Newco in accordance with the DLLCA.

The Merger Agreement provides that, at the effective time of the First Merger, each issued and outstanding Newco common unit (except Newco common units held by Danaher, NetScout, Merger Sub or Newco) will be automatically converted into a number of shares of NetScout common stock equal to (x) 62.5 million shares of NetScout common stock plus the product of (A) 1.46 multiplied by (B) the number of shares of NetScout common stock issued in any acquisition by NetScout prior to the effective time of the First Merger divided by (y) the aggregate number of Newco common units issued and outstanding immediately prior to the effective time of the First Merger. Prior to the consummation of the Distribution, Newco will authorize the issuance of a number of Newco common units such that the total number of Newco common units outstanding immediately prior to the First Merger will be that number that results in the exchange ratio in the First Merger equaling one and, as a result, each Newco common unit (except Newco common units held by Danaher, Newco, NetScout or Merger Sub) will be converted into one share of NetScout common stock in the First Merger. The calculation of the merger consideration as set forth in the Merger Agreement is expected to result, prior to the elimination of fractional shares, in Newco’s members immediately prior to the merger collectively holding approximately 59.5% of the outstanding equity interests of NetScout on a fully-diluted basis immediately following the First Merger and NetScout’s stockholders immediately prior to the First Merger collectively holding approximately 40.5% of such equity interests on a fully-diluted basis.

No fractional shares of NetScout common stock will be issued pursuant to the First Merger. Any holder of Newco common units who would otherwise be entitled to receive a fraction of a share of NetScout common stock (after aggregating all fractional shares issuable to such holder) shall, in lieu of such fraction of a share, be paid in cash the dollar amount (rounded to the nearest whole cent), after deducting any required withholding taxes, on a pro rata basis, without interest, determined by multiplying such fraction by the closing price of a share of NetScout common stock on NASDAQ on the last business day prior to the closing of the First Merger.

NetScout Dividend Policy

NetScout currently intends to retain its future earnings, if any, to finance the development and expansion of its business and is limited in its ability to pay cash dividends under the terms of its current credit facility. Therefore, NetScout does not intend to pay cash dividends on its common stock for the foreseeable future. Any future determination to pay dividends will be at the discretion of NetScout’s board of directors and will depend on NetScout’s financial condition, results of operations and capital requirements, restrictions contained in any financing instruments and such other factors as the NetScout board of directors deems relevant.

RISK FACTORS

You should carefully consider the following risks, together with the other information contained or incorporated by reference in this document and the annexes hereto. Some of the risks described below relate principally to the business and the industry in which NetScout, including the Communications Business, will operate after the Transactions, while others relate principally to the Transactions. The remaining risks relate principally to the securities markets generally and ownership of shares of NetScout common stock. For a discussion of additional uncertainties associated with forward-looking statements in this document, please see the section entitled “Cautionary Statement Concerning Forward-Looking Statements.” In addition, you should consider the risks associated with NetScout’s business that appear in NetScout’s Annual Report on Form 10-K for the year ended March 31, 2014 and NetScout’s Quarterly Report on Form 10-Q for the period ended September 30, 2014, which are incorporated by reference into this document.

Risks Related to the Transactions

The calculation of the merger consideration will not be adjusted if the value of the business or assets of the Communications Business declines or if the value of NetScout increases before the Mergers are completed.

The calculation of the number of shares of NetScout common stock to be distributed in the Mergers will not be adjusted if the value of the business or assets of the Communications Business declines prior to the consummation of the Mergers or the value of NetScout increases prior to the Mergers. NetScout will not be required to consummate the Mergers if there has been any “material adverse effect” (as this term is described in the section of this document entitled “The Merger Agreement—Representations and Warranties”) on the Communications Business. However, NetScout will not be permitted to terminate the Merger Agreement or resolicit the vote of NetScout stockholders because of any changes in the market prices of NetScout’s common stock or any changes in the value of the Communications Business that do not constitute a material adverse effect on the Communications Business.

Upon completion of the Transactions, NetScout will incur significant expenses in connection with the integration of the Communications Business.

Upon completion of the Transactions, NetScout expects to incur significant expenses in connection with the integration of the Communications Business, including integrating products and technology, personnel, information technology systems, accounting systems, suppliers, and channel partners of each business and implementing consistent standards, policies, and procedures, and may possibly be subject to material write downs in assets and charges to earnings, which may include severance pay and other costs.

NetScout will assume certain non-U.S. pension benefit obligations associated with the Communications Business. Future funding obligations related to these liabilities could restrict cash available for NetScout’s operations, capital expenditures or other requirements, or require NetScout to borrow additional funds.

In the Transactions, NetScout will assume certain funded and unfunded non-U.S. pension obligations related to non-U.S. employees of the Communications Business who become employees of Newco to the extent the assumption is required by applicable law. In connection therewith, Danaher will transfer to NetScout all assets set aside by Danaher to fund such non-U.S. pension obligations related to the Communications Business. If the non-U.S. pension liabilities transferred by Danaher exceed the assets transferred by Danaher, Danaher is obligated to transfer an amount of cash to NetScout equal to the difference between the non-U.S. pension liabilities transferred and the assets transferred. The transfers of assets and non-U.S. pension liabilities will be governed by applicable law, provided that if the mechanism for the transfers is not mandated by applicable law, the assets and liabilities will be transferred on a projected benefit obligation basis in accordance with GAAP.

29

##### Table of Contents

Funding obligations with respect to non-U.S. pension plans change due to, among other things, the actual investment return on plan assets. Continued volatility in the capital markets may have a further negative impact on the funded status of the non-U.S. pension plans, which may in turn increase attendant funding obligations. Changing economic conditions, poor pension investment returns or other factors may require NetScout to make substantial cash contributions to the pension plans in the future, preventing the use of increased cash contributions for other purposes and adversely affecting NetScout’s liquidity.

While NetScout intends to comply with any future funding obligations for its non-U.S. pension benefit plans through the use of cash from operations, there can be no assurance that NetScout will generate enough cash to do so and also meet its other required or intended cash uses. NetScout’s inability to fund these obligations through cash from operations could require it to seek funding from other sources, including through additional borrowings, which could materially increase NetScout’s outstanding debt or debt service requirements.

Current NetScout stockholders’ ownership interest in NetScout will be substantially diluted in the Mergers.

Following the consummation of the Mergers, NetScout’s stockholders will, in the aggregate, own a significantly smaller percentage of NetScout than they will own of NetScout immediately prior to the Mergers. Following the consummation of the Mergers, NetScout’s stockholders immediately prior to the Mergers are expected to collectively hold no more than approximately 40.5% of NetScout’s common stock immediately after the Mergers. Consequently, NetScout’s current stockholders, as a group, will be able to exercise less influence over the management and policies of NetScout following the Mergers than they will exercise over the management and policies of NetScout immediately prior to the Mergers.

Sales of NetScout common stock after the Transactions may negatively affect the market price of NetScout common stock.

The shares of NetScout common stock to be issued in the Transactions to holders of Newco common units will generally be eligible for immediate resale. The market price of NetScout common stock could decline as a result of sales of a large number of shares of NetScout common stock in the market after the consummation of the Transactions or even the perception that these sales could occur.

It is expected that immediately after consummation of the First Merger, pre-First Merger holders of Newco common units will hold approximately 59.5% of NetScout’s common stock on a fully-diluted basis and NetScout’s existing stockholders will hold approximately 40.5% of NetScout’s common stock on a fully-diluted basis, subject to potential adjustment under limited circumstances as described in the section of this document entitled “The Merger Agreement—Merger Consideration.” Currently, Danaher stockholders may include index funds that have performance tied to certain stock indices, and institutional investors subject to various investing guidelines. Because NetScout may not be included in these indices following the consummation of the Transactions or may not meet the investing guidelines of some of these institutional investors, these index funds and institutional investors may decide to or may be required to sell the NetScout common stock that they receive in the Transactions. In addition, the investment fiduciaries of Danaher’s defined contribution and defined benefit plans may decide to sell any NetScout common stock that the trusts for these plans receive in the Transactions, or may decide not to participate in the exchange offer, if applicable, in response to their fiduciary obligations under applicable law. These sales, or the possibility that these sales may occur, may also make it more difficult for NetScout to obtain additional capital by selling equity securities in the future at a time and at a price that it deems appropriate.

The historical financial information of the Communications Business may not be representative of its results or financial condition if it had been operated independently of Danaher and, as a result, may not be a reliable indicator of its future results.

The Communications Business is currently operated by Danaher. Consequently, the financial information of the Communications Business included in this document has been derived from the consolidated financial

30

##### Table of Contents

statements and accounting records of the Communications Business and reflects all direct costs as well as assumptions and allocations made by management of Danaher. The financial position, results of operations and cash flows of the Communications Business presented may be different from those that would have resulted had the Communications Business been operated independently of Danaher during the applicable periods or at the applicable dates. For example, in preparing the financial statements of the Communications Business, Danaher made allocations of costs and Danaher corporate expenses deemed to be attributable to the Communications Business. However, these costs and expenses reflect the costs and expenses attributable to the Communications Business operated as part of a larger organization and do not necessarily reflect costs and expenses that would be incurred by the Communications Business had it been operated independently. As a result, the historical financial information of the Communications Business may not be a reliable indicator of future results.

NetScout’s business, financial condition and results of operations may be adversely affected following the Transactions if NetScout cannot negotiate terms that are as favorable as those Danaher has received when NetScout replaces contracts after the closing of the Transactions.

Prior to consummation of the Transactions, certain functions (such as purchasing, information systems, sales, logistics and distribution) for the Communications Business are generally being performed under centralized systems that will not be transferred to NetScout and, in some cases, under contracts that are also used for Danaher’s other businesses and which are not intended to be assigned to NetScout with the Communications Business. In addition, some other contracts that Danaher or its subsidiaries are a party to on behalf of the Communications Business require consents of third parties to assign them to Newco. While Danaher, under the Transition Services Agreement, will agree to provide NetScout with certain services, there can be no assurance that NetScout will be able to obtain those consents or negotiate terms that are as favorable as those Danaher received when and if NetScout replaces these services with its own agreements for similar services. Although NetScout believes that it will be able to obtain any such consents or enter into new agreements for similar services, it is possible that the failure to obtain consents for or replace a significant number of these agreements for any of these services or to replace them on terms that as are as favorable as those Danaher has received could have a material adverse impact on NetScout’s business, financial condition and results of operations following the Transactions.

The Distribution could result in significant tax liability, and NetScout may be obligated to indemnify Danaher for any such tax liability imposed on Danaher.

Danaher will receive the Tax Opinion from Skadden to the effect that the Distribution offer will qualify as a tax-free transaction under Sections 355 and 368(a)(1)(D) of the Code and that the Mergers will qualify as a tax-free transaction under Section 368(a)(1)(A) of the Code. Assuming that the Distribution and the Mergers so qualify, for U.S. federal income tax purposes, no gain or loss will be recognized by a holder of Danaher common stock upon the receipt of Newco common units in the Distribution or upon the exchange of Newco common units for NetScout common stock pursuant to the First Merger other than with respect to cash received in lieu of fractional shares, and Danaher will not recognize gain or loss with respect to the transfer of Newco units pursuant to the Distribution. Danaher also intends to seek a ruling from the IRS regarding certain issues relevant to the qualification of the Distribution and certain other aspects of the Separation for tax-free treatment for U.S. federal income tax purposes.

Although the IRS ruling, if received, will generally be binding on the IRS, the continuing validity of such ruling will be subject to the accuracy of factual representations and assumptions made in the ruling request. Also, as part of the IRS’s general policy with respect to rulings on spin-off and split-off transactions (including the Distribution), the IRS will not rule on the overall qualification of the transaction for tax-free treatment, but instead only on certain significant issues related thereto. As a result of this IRS policy, Danaher will obtain the opinion of counsel described above. The opinion will be based upon various factual representations and assumptions, as well as certain undertakings made by Danaher and Newco. If any of those factual representations or assumptions are untrue or incomplete in any material respect, any undertaking is not complied with, or the

31

##### Table of Contents

facts upon which the opinion will be based are materially different from the facts at the time of the Distribution, the Distribution may not qualify for tax-free treatment. Opinions of counsel are not binding on the IRS. As a result, the conclusions expressed in the opinion of counsel could be challenged by the IRS, and if the IRS prevails in such challenge, the tax consequences to Danaher and its stockholders could be materially unfavorable.

If the Distribution were determined not to qualify for non-recognition of gain and loss under Sections 355 and 368(a)(1)(D) of the Code, Danaher would generally recognize gain with respect to the transfer of Newco common units in the Distribution.

The Distribution and certain aspects of the Separation could be taxable to Danaher if Newco, its unit holders, NetScout or NetScout’s stockholders were to engage in a Disqualifying Action. In such cases, under the Tax Matters Agreement, Newco and NetScout will be required to indemnify Danaher against any taxes resulting from the Distribution or certain aspects of the Separation that arise as a result of a Disqualifying Action. If Danaher were to recognize gain on the Distribution or certain aspects of the Separation for reasons not related to a Disqualifying Action by Newco or NetScout, Danaher would not be entitled to be indemnified under the Tax Matters Agreement and the resulting tax to Danaher could have a material adverse effect on Danaher. If Newco or NetScout were required to indemnify Danaher as a result of the Distribution or certain aspects of the Separation being taxable, this indemnification obligation would likely be substantial and could have a material adverse effect on NetScout, including with respect to its financial condition and results of operations.

NetScout is required to abide by potentially significant restrictions which could limit NetScout’s ability to undertake certain corporate actions (such as the issuance of NetScout common stock or the undertaking of a merger or consolidation) that otherwise could be advantageous.

To preserve the tax-free treatment to Danaher and/or its stockholders of the Distribution and certain related transactions, under the Tax Matters Agreement, NetScout is restricted from taking any action that prevents such transactions from being tax-free for U.S. federal income tax purposes. These restrictions may limit NetScout’s ability to pursue certain strategic transactions or engage in other transactions, including using NetScout common stock to make acquisitions and in connection with equity capital market transactions that might increase the value of NetScout’s business. See “Additional Material Agreements—Tax Matters Agreement” for a detailed description of these restrictions.

Failure to consummate the Transactions could adversely impact the market price of NetScout’s common stock as well as NetScout’s business, financial condition and results of operations.

If the Transactions are not completed for any reason, the price of NetScout’s common stock may decline. In addition, NetScout may be subject to additional risks, including:

| • |  | depending on the reasons for and the timing of the termination of the Merger Agreement, the requirement in the Merger Agreement that NetScout pay Danaher a termination fee of $55 million or reimburse Danaher for certain out-of-pocket costs relating to the Transactions;

| • |  | substantial costs related to the Transactions, such as legal, accounting, regulatory filing, financial advisory and financial printing fees, which must be paid regardless of whether the Transactions are completed; and

The Merger Agreement contains provisions that may discourage other companies from trying to acquire NetScout. In addition, NetScout will have more shares of its common stock outstanding after the Transactions, which may discourage other companies from trying to acquire NetScout.

The Merger Agreement contains provisions that may discourage a third-party from submitting a business combination proposal to NetScout prior to the closing of the Transactions that might result in greater value to

##### Table of Contents

NetScout stockholders than the Transactions. For example, the Merger Agreement generally prohibits NetScout from soliciting any takeover proposal. In addition, if the Merger Agreement is terminated by NetScout or Danaher in circumstances that obligate NetScout to pay a termination fee or to reimburse transaction expenses to Danaher, NetScout’s liquidity or financial condition may be materially adversely affected as a result of such payment, and the requirement to make such a payment might deter third parties from proposing alternative business combination proposals. In addition, the Merger Agreement requires that NetScout seek stockholder approval for the issuance of shares of NetScout common stock in the Merger, even if the NetScout board of directors changes its recommendation regarding the issuance of shares of NetScout common stock in the Merger.

NetScout expects to issue 62.5 million shares of its common stock as part of the Transactions, assuming no adjustments pursuant to the Merger Agreement. Because NetScout will be a significantly larger company and have significantly more shares of its common stock outstanding after the Transactions, an acquisition of NetScout may become more expensive. As a result, some companies may not seek to acquire NetScout, and the reduction in potential parties that may seek to acquire NetScout could negatively impact the prices at which NetScout’s common stock trades.

NetScout’s estimates and judgments related to the acquisition accounting models used to record the purchase price allocation may be inaccurate.

Management will make significant accounting judgments and estimates for the application of acquisition accounting under US generally accepted accounting principles, and the underlying valuation models. NetScout’s business, operating results and financial condition could be materially and adversely impacted in future periods if NetScout’s accounting judgments and estimates related to these models prove to be inaccurate.

NetScout may be required to recognize impairment charges for goodwill and other intangible assets.

The proposed transaction will add approximately $2.7 billion of goodwill and other intangible assets to NetScout’s consolidated balance sheet. In accordance with US generally accepted accounting principles, management periodically assesses these assets to determine if they are impaired. Significant negative industry or economic trends, disruptions to NetScout’s business, inability to effectively integrate acquired businesses, unexpected significant changes or planned changes in use of the assets, divestitures and market capitalization declines may impair goodwill and other intangible assets. Any charges relating to such impairments would adversely affect results of operations in the periods recognized.

Other Risks that Relate to NetScout, Including the Communications Business, After the Transactions

NetScout’s failure to successfully integrate the Communications Business into its business within its expected timetable could adversely affect the combined company’s future results and the market price of NetScout’s common stock following the completion of the Transactions.

The success of the Transactions will depend, in large part, on NetScout’s ability, as a combined company following the completion of the Transactions to realize the anticipated benefits and on the sales and profitability of the combined company. To realize these anticipated benefits, the combined company must successfully integrate its respective businesses. This integration will be complex and time-consuming. The failure to successfully integrate and manage the challenges presented by the integration process may result in NetScout’s failure to achieve some or all of the anticipated benefits of the Transactions.

Potential difficulties that may be encountered in the integration process include the following:

| • |  | Lost sales and customers as a result of customers of NetScout’s or the Communications Business deciding not to do business with the combined company;

| • |  | Complexities associated with managing the larger, more complex, combined business;

| • |  | Integrating personnel of NetScout’s and the Communications Business while maintaining focus on providing consistent, high quality products and service to customers;

33

##### Table of Contents

| • |  | The loss of key employees; and

| • |  | Potential unknown liabilities and unforeseen expenses, delays or regulatory conditions associated with the Transactions.

If any of these events were to occur, NetScout’s ability to maintain relationships with customers, channel partners, suppliers and employees or NetScout’s ability to achieve the anticipated benefits of the Transactions could be adversely affected, or could reduce NetScout’s sales or earnings or otherwise adversely affect NetScout’s business and financial results after the Transactions and, as a result, adversely affect the market price of NetScout’s common stock.

The success of the combined company will also depend on relationships with third parties and pre-existing customers and channel partners of NetScout and the Communications Business, which relationships may be affected by customer, channel partner or third-party preferences or public attitudes about the Transactions. Any adverse changes in these relationships could adversely affect the combined company’s business, financial condition or results of operations.

The combined company’s success will depend on NetScout’s ability to maintain and renew relationships with pre-existing customers, channel partners, suppliers, and other third-parties of both NetScout and the Communications Business and NetScout’s ability to establish new relationships. There can be no assurance that the business of the combined company will be able to maintain and renew pre-existing contracts and other business relationships, or enter into or maintain new contracts and other business relationships, on acceptable terms, if at all. The failure to maintain important business relationships could have a material adverse effect on NetScout’s business, financial condition or results of operations as a combined company.

The growth of the combined company could suffer if the markets into which the combined company sells its products and services experience cyclicality.

The growth of the combined company will depend in part on the growth of the markets which the Communications Business serves. The Communications Business serves certain industries that have historically been cyclical and have experienced periodic downturns that have had a material adverse impact on demand for the products, software and services that the Communications Business offers. Any of these factors could adversely affect the business, financial condition and results of operations of the combined company in any given period.

Defects, quality issues, inadequate disclosure or misuse with respect to the products, software or services of the combined company could adversely affect the business, reputation and financial statements of the combined company.

Defects in, quality issues with respect to or inadequate disclosure of risks relating to the use of the combined company’s products, software and services, or the misuse of the combined company’s products, software and services, could lead to lost profits and other economic damage, property damage, violation of privacy rights, personal injury or other liability resulting in third party claims, criminal liability, significant costs, damage to its reputation and loss of business. Any of these factors could adversely affect the business, financial condition and results of operations of the combined company.

International economic, political, legal, compliance and business factors could negatively affect the financial statements and growth of the combined company.

The Communications Business derives significant sales from customers outside the U.S. and certain manufacturing operations, suppliers and employees of the Communications Business are located outside the U.S. The Communications Business expects to continue to increase its sales and presence outside the U.S., particularly in the high-growth markets. The Communications Business’ international business (and particularly its business in high-growth markets) is subject to risks that are customarily encountered in non-U.S. operations, any of which could negatively affect the business, financial condition and results of operations of the combined company.

| • |  | a material adverse change, event or occurrence affecting NetScout or the Communications Business prior to the closing of the Transactions delaying the Transactions or causing the companies to abandon the Transactions;

| • |  | problems arising in successfully integrating the Communications Business and NetScout, which may result in the combined company not operating as effectively and efficiently as expected;

In addition, other factors besides those listed here could adversely affect NetScout’s business and results of operations.

Because forward-looking statements are based on estimates and assumptions that are subject to significant business, economic and competitive uncertainties, many of which are beyond NetScout’s control or are subject to change, actual results could be materially different and any or all of these forward-looking statements may turn out to be wrong.

Many factors mentioned in this document and in NetScout’s annual and quarterly reports will be important in determining future results. Consequently, NetScout cannot assure you that expectations or forecasts expressed in such forward-looking statements will be achieved. Actual future results may vary materially.

INFORMATION ON THE SPECIAL MEETING

General; Date; Time and Place; Purposes of the Meeting

NetScout is furnishing this proxy statement to its stockholders in connection with the solicitation of proxies by its board of directors for use at a special meeting of stockholders to be held at [—] a.m. local time, on [—], 2015, or at any adjournments or postponements of the special meeting, for the purposes set forth in this document and in the accompanying notice of special meeting. The special meeting will be held at NetScout Systems, Inc., 310 Littleton Road, Westford, Massachusetts. At the special meeting, stockholders will be asked to:

| • |  | approve the issuance of shares of NetScout common stock in the First Merger;

| • |  | adjourn or postpone the special meeting, if necessary or appropriate, to solicit additional proxies if there are not sufficient votes at the time of the special meeting to approve the issuance of shares of NetScout common stock in the First Merger; and

| • |  | transact any and all other business that may properly come before the special meeting or any adjourned or postponed session of the special meeting.

A copy of the Merger Agreement is attached to this document as Annex A. All stockholders of NetScout are urged to read the Merger Agreement carefully and in its entirety.

NetScout does not expect a vote to be taken on any other matters at the special meeting. If any other matters are properly presented at the special meeting for consideration, however, the holders of the proxies, if properly authorized, will have discretion to vote on these matters in accordance with their best judgment.

When this document refers to the “special meeting,” it is also referring to any adjourned or postponed session of the special meeting, if necessary or appropriate.

Record Date; Quorum; Voting Information; Required Votes

Holders of record of NetScout common stock at the close of business on [—], 2015, the record date for the special meeting, are entitled to notice of, and to vote at, the special meeting and any adjourned or postponed session thereof. At the close of business on the record date, [—] shares of NetScout common stock were outstanding and entitled to vote. Stockholders are entitled to one vote on each matter submitted to the stockholders for each share of NetScout common stock held as of the record date.

Shares entitled to vote at the special meeting may take action on a matter at the special meeting only if a quorum of those shares exists with respect to that matter. The presence at the meeting, in person or by proxy, of the holders of a majority of the outstanding shares of NetScout common stock entitled to vote at the special meeting will constitute a quorum for the transaction of business at the special meeting. If a share is represented for any purpose at the special meeting, it will be deemed present for purposes of determining whether a quorum exists. Abstentions and “broker non-votes” will be counted as present and entitled to vote for purposes of determining a quorum. “Broker non-votes” refer to votes that could have been cast on a matter in question by brokers with respect to uninstructed shares if the brokers had received their customers’ instructions.

The issuance of NetScout common stock in the First Merger must be approved by the affirmative vote of a majority of the shares of NetScout common stock represented and voting at the special meeting, either in person or by proxy. If NetScout’s stockholders fail to approve the issuance of shares of NetScout common stock in the First Merger upon a vote at the NetScout special meeting, each of Danaher and NetScout will have the right to terminate the Merger Agreement, as described in the section of this document entitled “The Merger Agreement—Termination.”

37

##### Table of Contents

The adjournment or postponement of the special meeting, if necessary or appropriate, to solicit additional proxies if there are not sufficient votes at the time of the special meeting to approve the issuance of shares of NetScout common stock in the First Merger must also be approved by the affirmative vote of a majority of the shares of NetScout common stock represented and voting at the special meeting, either in person or by proxy.

As of [—], 2015, NetScout’s directors and executive officers held [—]% of the shares entitled to vote at NetScout’s special meeting of the stockholders. As of [—], 2015, no affiliates of NetScout’s directors and executive officers held shares entitled to vote at NetScout’s special meeting of the stockholders. As of [—], 2015, Danaher owned approximately 2.9% of the outstanding shares of NetScout common stock. As of [—], 2015, Newco’s directors, executive officers and their affiliates did not hold shares entitled to vote at NetScout’s special meeting of the stockholders. Newco’s stockholders are not required to vote on any of the proposals, and Newco will not hold a special meeting of stockholders in connection with the Transactions.

Under the terms of the Voting Agreement between Anil Singhal and Danaher, Anil Singhal has agreed in writing to vote his shares, and has granted Danaher a proxy to vote his shares, in favor of the Mergers and against any competing or superior proposals or proposals that would hinder or delay the completion of the Mergers. NetScout estimates that Anil Singhal holds approximately 5.5% of the voting power of the outstanding NetScout common shares with respect to the proposal to issue NetScout common shares in the First Merger. For a more complete description of the Voting Agreement, see “Voting Agreement.” In addition, Danaher intends to vote the shares of NetScout common stock that Danaher owns, representing approximately 2.9% of the outstanding shares of NetScout common stock as of October 10, 2014, in favor of the issuance of shares of NetScout common stock in the First Merger.

Recommendation of Board of Directors

After careful consideration, the board of directors of NetScout resolved that the Transactions contemplated by the Merger Agreement are advisable and fair to, and in the best interests of, NetScout and its stockholders and unanimously approved the Merger Agreement, the Mergers and the other Transactions. The NetScout board of directors recommends that the stockholders of NetScout vote “FOR” approval of the issuance of shares of NetScout common stock in the First Merger, and, if necessary or appropriate, “FOR” the adjournment or postponement of the special meeting to solicit additional proxies if there are not sufficient votes at the time of the special meeting to approve the issuance of shares of NetScout common stock in the First Merger.

How to Vote

NetScout stockholders can vote in person by completing a ballot at the NetScout special meeting, or NetScout stockholders can vote before the NetScout special meeting by proxy. Even if NetScout stockholders plan to attend the special meeting, NetScout encourages its stockholders to vote their shares as soon as possible by proxy. NetScout stockholders can vote by proxy using the enclosed proxy card, or by internet or by telephone as discussed below.

Holder of Record

NetScout holders of record may vote in person at the special meeting, vote by proxy over the telephone, vote by proxy through the internet, or vote by proxy by mail using the enclosed proxy card. Whether or not NetScout stockholders plan to attend the meeting, we urge each NetScout stockholder to vote by proxy to ensure its vote is counted. A NetScout stockholder may still attend the meeting in person even if it has already voted by proxy.

| • |  | To vote in person, a NetScout stockholder should come to the special meeting and we will give it ballot when it arrives.

| • |  | To vote using the proxy card, simply complete, sign and date the enclosed proxy card and return it promptly by mail in the envelope provided. If a NetScout stockholder returns a signed proxy card to us before the special meeting, we will vote that NetScout stockholder’s shares as directed.

38

##### Table of Contents

| • |  | To vote over the telephone, dial the toll-free number specified on the enclosed proxy card using a touch-tone phone and follow the recorded instructions. NetScout stockholders will be asked to provide the company number and control number from the proxy card. Telephone votes must be received by 11:59 p.m. Eastern Time on [—], 2015 to be counted.

| • |  | To vote through the internet, go to the website specified on the enclosed proxy card to complete an electronic proxy card. NetScout stockholders will be asked to provide the company number and control number from the proxy card. Internet votes must be received by 11:59 p.m. Eastern time on [—] to be counted.

Beneficial Owner

If a NetScout stockholder is a beneficial owner of shares registered in the name of a bank, broker or other nominee, that NetScout stockholder should have received a notice containing voting instructions from that organization rather than from NetScout. A NetScout stockholder should simply follow the voting instructions to ensure that its vote is counted. Alternatively, a NetScout stockholder may vote by telephone or over the internet as instructed by its bank, broker or other nominee. To vote in person at the special meeting, a NetScout stockholder must obtain a valid proxy from its bank, broker or other nominee. A NetScout stockholder should follow the instructions from its bank, broker or other nominee included with these proxy materials, or contact its bank, broker or other nominee to request a proxy form.

If a NetScout stockholder returns a signed and dated proxy card or otherwise votes without marking voting selections, its shares will be voted “FOR” approval of the issuance of shares of NetScout common stock in the First Merger and “FOR” the proposal to approve the adjournment or postponement of the special meeting, if necessary or appropriate, to solicit additional proxies, and in accordance with the recommendations of the NetScout board of directors on any other matters properly brought before the special meeting for a vote or any adjourned or postponed session of the special meeting.

Solicitation of Proxies

NetScout will bear the entire cost of soliciting proxies from its stockholders. In addition to solicitation of proxies by mail, proxies may be solicited in person, by telephone or other electronic communications, such as emails or postings on NetScout’s website by NetScout’s directors, officers and employees, who will not receive additional compensation for these services. NetScout has retained Innisfree M&A Incorporated to assist in the solicitation of proxies for an initial fee of $25,000 plus reimbursement for various expenses incurred in conjunction with the delivery of its services. Brokerage houses, nominees, custodians and fiduciaries will be requested to forward soliciting material to beneficial owners of stock held of record by them, and NetScout will reimburse those persons for their reasonable expenses in doing so.

Revocation of Proxies

If a holder of record of NetScout common stock has properly completed and submitted its proxy card, the NetScout stockholder can change its vote in any of the following ways:

| • |  | by sending a signed notice of revocation to the Secretary of NetScout that is received prior to the special meeting stating that the NetScout stockholder revokes its proxy;

| • |  | by properly completing a new proxy card bearing a later date and properly submitting it so that it is received prior to the special meeting;

| • |  | by logging onto the internet website specified on the proxy card in the same manner a stockholder would to submit its proxy electronically or by calling the toll-free number specified on the proxy card prior to the special meeting, in each case if the NetScout stockholder is eligible to do so and following the instructions on the proxy card; or

| • |  | by attending the special meeting and voting in person.

39

##### Table of Contents

Simply attending the special meeting will not revoke a proxy. In the event of multiple online or telephone votes by a stockholder, each vote will supersede the previous vote and the last vote cast will be deemed to be the final vote of the stockholder unless such vote is revoked in person at the special meeting.

If a NetScout stockholder holds shares in “street name” through its bank, broker or other nominee, and has directed such person to vote its shares, it should instruct such person to change its vote, or if in the alternative a NetScout stockholder wishes to vote in person at the special meeting, it must bring to the special meeting a letter from the bank, broker or other nominee confirming its beneficial ownership of the shares and that the bank, broker or other nominee is not voting the shares at the special meeting.

Adjournments and Postponements

Although it is not currently expected, the special meeting may be adjourned or postponed, if necessary, for the purpose of soliciting additional proxies if there are not sufficient votes at the time of the special meeting to approve the issuance of shares of NetScout common stock in the First Merger. Any adjournment or postponement may be made from time to time by the affirmative vote of a majority of the shares of NetScout common stock represented and voting at the special meeting, either in person or by proxy, without further notice other than by an announcement made at the special meeting. Any adjournment or postponement of the special meeting for the purpose of soliciting additional proxies will allow NetScout stockholders who have already sent in their proxies to revoke them at any time prior to their use at the special meeting as adjourned or postponed.

The adjournment or postponement proposal relates only to an adjournment or postponement of the special meeting occurring for purposes of soliciting additional proxies for the approval of the issuance of shares of NetScout common stock in the First Merger. NetScout’s board of directors retains full authority to adjourn or postpone the special meeting for any other purpose, including the absence of a quorum, or to postpone the special meeting before it is convened, without the consent of any stockholders.

Attending the Special Meeting

All NetScout stockholders, including holders of record and stockholders who hold their shares through banks, brokers or other nominees, are invited to attend the NetScout special meeting. Holders of record can vote in person at the special meeting. Cell phones must be turned off prior to entering the special meeting. Cameras and video, audio or any other electronic recording devices will not be allowed in the meeting room during the special meeting, other than for NetScout purposes.

NetScout does not expect representatives of either PricewaterhouseCoopers LLP or Ernst & Young LLP to be present at the special meeting.

Householding

SEC rules allow delivery of a single document to households at which two or more stockholders reside. Accordingly, stockholders sharing an address who have been previously notified by their bank, broker or other nominee or its intermediary will receive only one copy of this document, unless the stockholder has provided contrary instructions. Individual proxy cards or voting instruction forms (or electronic voting facilities) will, however, continue to be provided for each stockholder account. This procedure, referred to as “householding,” reduces the volume of duplicate information received by stockholders, as well as NetScout’s expenses. Stockholders having multiple accounts may have received householding notifications from their respective banks, brokers or other nominees and, consequently, such stockholders may receive only one document.

Stockholders who prefer to receive separate copies of the document may request to receive separate copies of the document by notifying NetScout’s Secretary in writing or by telephone at the following address: NetScout Systems, Inc., Attn: Secretary, 310 Littleton Road, Westford, Massachusetts 01886, telephone: (978) 614-4000.

NetScout will provide the document promptly upon request. Stockholders currently sharing an address with another stockholder who wish to have only one proxy statement and annual report delivered to the household in the future should also contact NetScout’s Secretary.

INFORMATION ON THE DISTRIBUTION

In the Transactions, Danaher will distribute 100% of the Newco common units to Danaher stockholders through either an exchange offer followed by, in the event the exchange offer is not fully subscribed, a spin-off distribution or in a spin-off distribution not including an exchange offer. In the case of an exchange offer, Danaher will offer its stockholders the option to exchange all or a portion of their shares of Danaher common stock for Newco common units. In the event the exchange offer is not fully subscribed, Danaher will distribute the remaining Newco common units owned by Danaher on a pro rata basis to Danaher stockholders whose shares of Danaher common stock remain outstanding after consummation of the exchange offer. If the Distribution is structured as a spin-off not including an exchange offer, Danaher will distribute in the spin-off the Newco common units owned by Danaher on a pro rata basis to Danaher stockholders. See “The Transactions.” Newco has filed a registration statement on Form S-4 and Form S-1 to register the Newco common units, which will be distributed to Danaher stockholders pursuant to the Distribution. The Newco common units will be immediately converted into shares of NetScout common stock in the First Merger. NetScout has filed a registration statement on Form S-4 to register the shares of its common stock, which will be issued in the First Merger. NetScout and NetScout stockholders are not a party to the Distribution and are not being asked to separately vote on the exchange offer, the spin-off or to otherwise participate in the exchange offer.

Upon consummation of the Distribution, Danaher will irrevocably deliver to an agent selected by Danaher a global certificate representing all of the Newco common units being distributed. Shares of NetScout common stock will be delivered immediately following the Distribution and the effectiveness of the Merger, pursuant to the procedures determined by the agent and Danaher’s transfer agent.

In the Mergers, NetScout expects to issue an aggregate number of shares of common stock of NetScout equal to (x) 62.5 million shares of NetScout common stock plus the product of (A) 1.46 multiplied by (B) the number of shares of NetScout common stock issued in any acquisition by NetScout prior to the effective time of the First Merger, divided by (y) the aggregate number of Newco common units issued and outstanding immediately prior to the effective time of the First Merger. Based upon the reported closing sale price of $[—] per share for NetScout common stock on NASDAQ on [—], 2015, the total value of the consideration to be paid by NetScout in the Transactions would have been approximately $[—] billion. The value of the consideration to be paid by NetScout in the Mergers will fluctuate with the market price of NetScout common stock until the Mergers are consummated.

The information included in this section regarding Danaher’s exchange offer, if applicable, is being provided to NetScout’s stockholders for informational purposes only and does not purport to be complete. For additional information on Danaher’s exchange offer and the terms and conditions of Danaher’s exchange offer, NetScout stockholders are urged to read Newco’s registration statement on Form S-4 and Form S-1, or NetScout’s registration statement on Form S-4, and all other documents Newco will file with the SEC. This document constitutes only a proxy statement for NetScout stockholders relating to the approval of the issuance of shares of NetScout common stock in the Mergers and is not an offer to sell or an offer to purchase shares of NetScout common stock.

INFORMATION ON NETSCOUT

Overview

NetScout was founded in 1984 and is headquartered in Westford, Massachusetts. NetScout is an industry leader for advanced network, application and service assurance solutions, providing high-quality performance analytics and operational intelligence solutions that facilitate the evolution toward new computing paradigms, such as virtualization, mobility and cloud. NetScout designs, develops, manufactures, markets, licenses, sells and supports these products focused on assuring service delivery quality, performance and availability for some of the world’s largest, most demanding and complex internet protocol (IP) based service delivery environments. NetScout manufactures and markets these products in integrated hardware and software solutions that are used by commercial enterprises, large governmental agencies and telecommunication service providers worldwide. NetScout has a single operating segment and substantially all of its identifiable assets are located in the United States.

NetScout’s Business After the Transactions

NetScout believes that the Transactions will help support the following key elements of its growth strategy:

Drive technology innovation. NetScout will continue to invest in research and development, and leverage the strong technical and domain expertise across its organization. As a result of the acquisition of Danaher’s Communications business, NetScout’s base of research and development professionals will more than quadruple from its current level of over 350 people and the combined company’s engineering teams will be focused on advancing technical innovation across its broad product portfolio. By capitalizing on NetScout’s extensive experience with global enterprise, service provider and government organizations with IP-based networks, NetScout will be well positioned to cross-leverage its technology development across all major platforms and relevant technologies to address the evolving demands of current and prospective customers. NetScout works closely with its largest enterprise and service provider customers to better understand and address their near-term and longer-term requirements. By better understanding the key, time-sensitive needs of NetScout’s global customer base, NetScout will continue to enhance and extend its product line to meet the increasing challenges of managing a diverse range of services over an increasingly global network environment.

Enable pervasive visibility. NetScout intends to continue to expand its intelligent data source family to enable its customers to achieve greater visibility into more places across their end-to-end network environment. NetScout plans to integrate various capabilities, including its Adaptive Session Intelligence software, across the combined company’s product portfolio to enable wider deployment of NetScout’s technology within virtual computing environments, network devices and computing platforms and to support a broader range of network and application performance management, security and business intelligence requirements. This includes fortifying and enhancing NetScout’s capabilities and technologies by supporting new and innovative ways to address the ongoing challenges associated with the increasing volume of data traffic and enable scalable support for 40 Gigabit, 100 Gigabit topologies and increasing global deployments of IPv6. Advancing these capabilities will enable NetScout to cross-sell a wider range of solutions into NetScout’s existing base of customers using solutions from Danaher’s Communications business, as well as increase business with the current base of Danaher Communications customers by cross-selling NetScout solutions.

Continued portfolio enhancements. NetScout plans to continue to enhance its products and solutions to address the management challenges associated with virtualization, cloud computing, service-oriented architectures, VoIP, video, and telepresence technologies. In addition, NetScout will continue to drive its solutions to help IT organizations address the challenges of complex service delivery, datacenter consolidation, branch office consolidation and optimization, increasing mobility and the move to a more process-oriented operating environment. The acquisition will add Tektronix Communications’ high-value troubleshooting capabilities, which targets service providers, with Fluke Networks’ troubleshooting capabilities, which targets small to mid-sized enterprises. These capabilities are expected to complement NetScout’s traditional strengths in monitoring

large, complex IP-based networks and the mission-critical services that run across them. Over the longer term, NetScout anticipates that the post-acquisition product roadmap integration would support migrating key features and functionalities from various product platforms into new, higher value solutions at more attractive price points that will appeal to a broader range of customers globally.

Extension into Adjacent Markets: By enhancing and expanding NetScout’s product portfolio, NetScout can also enter complementary adjacent markets that will help it further expand its customer relationships and increase its total addressable market. For example, the acquisition of the Arbor Networks business will bring new security offerings that complement NetScout’s core range of solutions by helping customers identify, mitigate and remediate complex technical threats and unauthorized intrusions into their network and IT infrastructures. The Arbor business will accelerate NetScout’s entry into cyber security with market-leading solutions used by leading service providers and enterprises to prevent and mitigate distributed denial of service (DDoS) attacks. In addition, the acquisition will bring new solutions for optimizing the radio access networks (RANs) of service providers and sophisticated business intelligence analytics that are used by service providers to increase customer satisfaction, reduce churn, and increase profits.

Leverage NetScout’s direct sales force and pursue cross-selling opportunities. As a result of the acquisition, NetScout will have a larger direct sales force with specialized expertise in targeting the enterprise, service provider and government markets. Each of these markets has different technology issues, challenges and sales cycles. To augment NetScout’s direct sales resources, particularly in key international markets, NetScout plans to leverage relationships with a range of value-added resellers and systems integrators that have historically supported Tektronix Communications, Arbor Networks and the acquired portions of the Fluke Networks Enterprise businesses. These firms possess specialized technical capabilities and local market knowledge, and NetScout believes that they will be important partners to support NetScout following the Transactions. Consequently, NetScout will be very well positioned to better meet the needs of these diverse markets. Additionally, NetScout believes that the Transactions will help create a range of attractive opportunities for the direct sales force to cross-sell various products into NetScout’s customer base. For example, NetScout will seek to leverage its strong relationships with its enterprise customers to accelerate adoption of Arbor Networks’ cyber security solutions and bring additional cyber security solutions to the marketplace that can take advantage of Arbor’s established customer relationships; NetScout also will focus on broadening its relationships with its existing service provider customers by driving sales of the Tektronix Communications’ RAN solutions and cross-selling Tektronix Communications’ business intelligence analytics into new departments.

Increase market relevance and awareness. The acquisition will substantially expand NetScout’s customer base around the world. To generate increased demand for NetScout’s products, NetScout will implement marketing campaigns aimed at promoting its thought leadership and driving lead generation for its technology, products and solutions among both enterprise and service provider customers. In addition, NetScout will continue to drive industry initiatives around managing service delivery.

Extend NetScout’s technology partner alliance ecosystem. Supporting a larger, more global customer base as a result of the acquisition will require alliances with complementary solutions providers. NetScout plans to continue to enhance its technology value, product capabilities and customer relevance through the continued integration of NetScout’s products into technology partner products. This includes both interoperability integration efforts, as well as embedding NetScout’s technology into alliance partner products to gain a more pervasive footprint across both enterprise and service provider networks.

Pursue strategic acquisitions. Prior to the Transactions, NetScout completed five acquisitions in recent years that helped broaden the Company’s capabilities, products and technologies, and better position the Company to meet the needs of its customers and prospects. Following the Transactions, NetScout plans to be opportunistic in pursuing strategic acquisitions in order to achieve key business and technology objectives.

Improve cost structure and drive efficiencies. NetScout believes that the Transactions will create a range of opportunities to further improve the Company’s operating profitability by pursuing cost synergies. NetScout will seek to leverage its purchasing power and extend its proven manufacturing techniques in ways that can improve

product gross margin. In addition, NetScout plans to integrate certain operations that have previously been managed separately across various business and product lines. NetScout also expects to achieve synergies by using common infrastructure platforms, and by eliminating or reducing redundancies associated with pre-existing resources, programs and capabilities.

NetScout’s Liquidity and Capital Resources After the Transactions

Overview

NetScout’s principal use of its liquidity and capital for six months ended September 30, 2014 was to support its operations, including the payment of routine liabilities, to maintain and improve NetScout’s facilities and systems and to pay variable and incentive compensation to its employees. NetScout’s capital deployment priorities included investments in product development as well as a share repurchase program focusing on the repurchase of incremental shares issued in relation to NetScout’s employee stock compensation programs. For the six months ended September 30, 2014, cash provided by operating activities was approximately $29 million, capital expenditures were approximately $4 million and free cash flow, a non-GAAP measure defined as net cash provided by operating activities less capital expenditures and the purchase of intangible assets, was $25 million. Net cash used in investing activities was approximately $25.6 million, net cash used in financing activities was approximately $27 million primarily because of share repurchases of approximately $31 million. NetScout’s cash, cash equivalents and marketable securities were approximately $217 million as of September 30, 2014.

For the nine month period ended September 26, 2014, cash provided by the operating activities of the Communications Business was approximately $62 million, capital expenditures were approximately $12 million, and free cash flows (as defined above) was approximately $50 million. Net cash used in investing activities was approximately $12 million and net cash paid for financing activities was approximately $50 million, including payments to its parent of approximately $47 million. Danaher has historically provided various services to the Communications Business including cash management and other treasury services. As such, the cash and liquidity is maintained at the Danaher corporate level.

Following the consummation of the Transactions, NetScout expects cash from operating activities to be in the range of $200.0 million to $250.0 million during the first year of the combined operations. Due to the low capital intensive nature of the combined business, NetScout expects that capital expenditures will continue to be less than 5 percent of total combined revenue following the consummation of the Transactions. NetScout expects to incur approximately $11 million of investment banking fees. Since the integration planning is in the beginning phases, there is no estimate of costs associated with achieving any of the projected synergies or the consolidation of any operations and systems as well as professional fees associated with these activities. Additionally, as part of the Merger Agreement, the Communications Business will enter into a Transition Services Agreement with Danaher, under which Danaher will provide the Communications Business specified support services and other assistance for a limited time following the closing of the Transactions. Certain of the services covered under the Transition Services Agreement are costs that are currently included as operating costs in the Communications Business Combined Statements of Earnings, however, there is no guarantee that the Communications Business will not incur higher operating costs than those reflected in those financial statements and NetScout may incur certain costs to replace services at the end of the Transition Services Agreement.

NetScout anticipates that its primary sources of liquidity for working capital and operating activities will be cash provided by operations as well as a financing arrangement which is being reviewed. While NetScout has an existing Revolving Credit Agreement for $250 million that is fully available, NetScout is reviewing alternative financing arrangements including amending the existing facility to cover the requirements of the combined entity. NetScout expects these sources of liquidity will be sufficient to fund working capital and capital expenditure requirements, including the significant one-time costs relating to the Transactions described above.

INFORMATION ON THE COMMUNICATIONS BUSINESS

General

The Communications Business has been operated as Danaher Corporation’s Communications platform since 2008. Danaher created the Communications platform from the enterprise network performance management and diagnostics business of Fluke Networks Enterprise, which Danaher acquired in 1998, the telecommunications network monitoring, subscriber troubleshooting and diagnostics business of Tektronix, Inc., which Danaher acquired in 2007, the network security solutions business of Arbor Networks, Inc., which Danaher acquired in 2010, as well as from the acquisitions of AirMagnet and Aran Technologies in 2009, VSS Monitoring. In 2012 and Newfield Wireless and PacketLoop in 2013. Danaher established its Communications platform primarily to address the market opportunities arising from the convergence of telecommunication and enterprise technologies, which historically had been relatively distinct but have converged as a result of the emergence of internet protocol as the predominant underlying technology for both applications.

Today, the Communications Business is a leading provider of products and solutions used in the design, deployment, monitoring and security of traditional, virtualized, mobile and cloud-based networks operated by communications service providers, hosting service providers, enterprises and government agencies worldwide. The Communications Business derives revenue principally by developing, manufacturing, and selling a broad range of hardware, software and support services.

The Communications Business designs, manufactures, markets, licenses, sells and supports innovative hardware and software solutions that help its customers deploy, manage and secure their communication network technologies and services. Communication networks include telecommunication and other service provider networks as well as enterprise networks. The Communications Business’ solutions collect and analyze massive volumes of voice, video and data traffic that traverse communication networks. The data the Communications Business collects is in the form of “packets” (also known as network data) and “flows” (also known as machine data). These forms of data provide granular detail regarding what is occurring within communication networks, both in real-time and historically. The Communications Business’ solutions allow its customers to analyze the large amount of packets and flows on their communication networks. From these packets and flows the Communications Business’ analytics solutions derive contextual and correlated insights about what is occurring at different physical points and times in a network. These insights help the Communications Business’ customers to:

| • |  | improve the quality of their end users’ experience;

| • |  | monitor the performance of their network infrastructure and the services it delivers;

| • |  | troubleshoot customer service and operational problems across vast, complex networks;

| • |  | enable and deliver location-based services for their mobile subscribers; and

| • |  | detect and mitigate cyber security events in their network, including distributed denial-of-service (“DDoS”) attacks and advanced persistent threats (“APT”).

The Communications Business’ product offerings include the following:

| • |  | telecommunications network monitoring systems for performance management and troubleshooting;

| • |  | cyber security detection and mitigation systems for service provider and enterprise networks;

Businesses in multiple industry verticals (including wireless and fixed-line communications service providers, hosting service providers, enterprises and governmental agencies) use the Communications Business’ solutions to reduce operating expenses and improve the performance and availability of their communications networks. The Communications Business’ broad portfolio of solutions addresses the “end-to-end” needs of large, physically diversified networks: from centralized information technology data centers and network operations centers to the remote access points of networks such as enterprise branch offices and mobile telecommunications “cell towers.”

Sales to the Communications Business’ two largest customers, AT&T and Verizon, were 25% and 11%, respectively, of total sales in 2013, 23% and 10%, respectively, of total sales in 2012 and 31% and 2%, respectively, of total sales in 2011.

The Communications Business’ products and solutions are marketed under the AIRMAGNET, ARBOR NETWORKS, FLUKE NETWORKS, TEKTRONIX COMMUNICATIONS and VSS MONITORING brands.

Strategy

The Communications Business’ management believes there are several key trends driving growth in the Communications Business’ served markets, including the:

| • |  | proliferation of “smart” devices, including mobile phones and machine-to-machine and “Internet of Things” communications;

| • |  | increasing sophistication of “real-time” communications services requiring superior network performance and availability;

| • |  | growing prevalence of cyber security attacks (such as DDoS and APT) on network integrity and availability;

| • |  | new investments in network function virtualization (“NFV”) and software defined networks (“SDN”);

| • |  | continuing transition of “premise-based” infrastructures and services to “cloud-based” infrastructure and services; and

| • |  | increasing demand for the extraction of insights from “Big Data” such as the traffic traversing communication networks.

The Communications Business’ management believes communications service providers, enterprises and government agency network operators worldwide will continue to invest in solutions like the Communications Business’ to address the increasing complexities associated with these trends.

The Communications Business’ strategy is to focus on facilitating the deployment, management and security of the Communications Business’ customers’ communication network technologies and services. As the

| • |  | embracing the opportunities presented by the “cloud,” to improve the Communications Business’ competitive positioning and expand the size of the Communications Business’ addressable market;

| • |  | re-purposing the contextual and correlated insights the Communications Business derives from network traffic to serve not only the technical functions of the Communications Business’ customers but also the business and marketing functions; and

| • |  | leveraging the Communications Business’ broad footprint in monitoring internet traffic to help the Communications Business’ security solutions deployed in customer networks around the world better identify cyber security threats and fortify network defenses.

To accomplish this strategy, the Communications Business is investing in internal product development, pursuing strategic acquisitions as appropriate to gain access to technology, products, or markets and leveraging the Communications Business’ strong industry brands, customer relationships and global distribution channels.

Manufacturing and Materials

The Communications Business’ primary manufacturing activities occur at facilities located in North America. The Communications Business performs installation and integration activities at customer sites using internal direct labor and third-party integration providers. These installation and integration activities occur primarily at network operator sites located in all of the major geographic regions that the Communications Business serves.

The Communications Business’ manufacturing operations employ a variety of raw materials that the Communications Business purchases from independent sources around the world. No single supplier is material, although for some components that require particular specifications or qualifications there may be a single supplier or a limited number of suppliers that can readily provide such components. The Communications Business utilizes a number of techniques to address potential disruption in and other risks relating to its supply chain, including in certain cases the use of safety stock, alternative materials and qualification of multiple supply sources. During 2013, the Communications Business had no raw material shortages that had a material effect on its business.

Sales, Distribution and Backlog

The Communications Business maintains a direct sales and field maintenance organization, staffed with technically trained personnel throughout the world. Sales to end-customers are made through the Communications Business’ direct sales organization and to a lesser extent through independent distributors and resellers located in principal market areas. The Communications Business’ distribution strategy is to align the sales channel with the Communications Business’ customer base, concentrating direct selling efforts in large or strategic geographies and markets, and utilizing distributors or other partners to expand geographic and customer reach.

The Communications Business’ unfilled product and service orders were $357,334,000 as of December 31, 2013 and $398,404,000 as of December 31, 2012. A large majority of the unfilled orders will be delivered to customers within one year.

United States. In the United States, the Communications Business does not have any hourly-rated, unionized employees. Outside the United States, the Communications Business has government-mandated collective bargaining arrangements and union contracts in certain countries.

Regulatory Matters

The Communications Business faces government regulation both within and outside the United States relating to the development, manufacture, marketing, sale and distribution of its products, software and services. The following sections describe certain significant regulations that the Communications Business is subject to. These are not the only regulations that the Communications Business’ businesses must comply with.

Environmental, Health and Safety Laws and Regulations

The Communications Business’ operations, products and services are subject to environmental laws and regulations in the jurisdictions in which they operate, which impose limitations on the discharge of pollutants into the environment and establish standards for the generation, use, treatment, storage and disposal of hazardous and non-hazardous wastes. The Communications Business must also comply with various health and safety regulations in both the United States and abroad in connection with its operations. Compliance with these laws and regulations has not had and, based on current information and the applicable laws and regulations currently in effect, is not expected to have a material effect on the Communications Business’ capital expenditures, earnings or competitive position, and the Communications Business’ management does not anticipate material capital expenditures for environmental control facilities.

Export/Import Compliance

The Communications Business is required to comply with various U.S. export/import control and economic sanctions laws, including: (1) the Export Administration Regulations administered by the U.S. Department of Commerce, Bureau of Industry and Security, which, among other things, impose licensing requirements on the export or re-export of certain dual-use goods, technology and software (which are items that potentially have both commercial and military applications); (2) the regulations administered by the U.S. Department of Treasury, Office of Foreign Assets Control, which implement economic sanctions imposed against designated countries, governments and persons based on United States foreign policy and national security considerations; and (3) the import regulatory activities of the U.S. Customs and Border Protection. Other nations’ governments have implemented similar export and import control regulations, which may affect the Communications Business’ operations or transactions subject to their jurisdictions.

International Operations

The Communications Business’ products, software and services are available worldwide, and the Communications Business’ principal markets outside the United States are in Europe, Asia and Latin America. The Communications Business’ management believes that the Communications Business’ future growth depends in part on its ability to continue developing products and sales models that successfully target emerging markets. Annual revenue derived from customers outside the United States (based on geographic destination) as a percentage of total annual revenue was 41% in 2013, 42% in 2012 and 44% in 2011. Long-lived assets located outside the United States as a percentage of total long-lived assets as of December 31, 2013, 2012 and 2011 were 8%, 8% and 9%, respectively.

The manner in which the Communications Business’ products and services are sold outside the United States differs by product and by region. Most of the Communications Business’ sales in non-U.S. markets are made directly from the U.S., but it also sells products through various representatives and distributors. In countries with low sales volumes, the Communications Business often sells through representatives and distributors as well as other partners such as third party system integrators. Financial information about the Communications Business’ international operations is contained in Note 15 of the Communications Business’ Combined Financial Statements for the year ended December 31, 2013.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND

RESULTS OF OPERATIONS

Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) is designed to provide a reader of the financial statements with a narrative from the perspective of the management of the Communications Business. The MD&A should be read in conjunction with the Communications Business’ Combined Financial Statements for the nine months ended September 26, 2014 and the year ended December 31, 2013. The MD&A is divided into five sections:

| • |  | Basis of Presentation and Overview

| • |  | Results of Operations

| • |  | Risk Management

| • |  | Liquidity and Capital Resources

| • |  | Critical Accounting Estimates

BASIS OF PRESENTATION

The Communications Business consists of the Tektronix Communications and Arbor Networks businesses, and certain parts of the Fluke Networks Enterprise business of Danaher and is a leading provider of products and solutions used in the design, deployment, monitoring and security of traditional, virtualized, mobile and cloud-based networks operated by communications service providers, hosting service providers, enterprises and government agencies worldwide. The Communications Business derives revenue principally by developing, manufacturing, and selling a broad range of hardware, software and support services.

On October 13, 2014, Danaher announced a definitive agreement with NetScout to combine the Communications Business with NetScout whereby Danaher will distribute to its stockholders all of the common units of Newco, a wholly owned subsidiary. Prior to the closing of the distribution, Danaher will cause specified assets used in, and liabilities of, the Communications Business to be conveyed to Newco (the “Transaction” solely for purposes of this section). The distribution of the Newco common units to Danaher stockholders will be effected as either a spin-off transaction, a split-off transaction, or a combination split-off and spin-off, followed by a merger with a subsidiary of NetScout for consideration of 62.5 million NetScout shares, subject to adjustment. Both the distribution and merger are expected to qualify as tax-free transactions to Danaher and its stockholders, except to the extent that cash is paid to Danaher stockholders in lieu of fractional shares. If Danaher elects a spin-off, all Danaher stockholders will participate pro-rata. If Danaher elects a split-off, Danaher will conduct an exchange offer pursuant to which its stockholders will elect whether to exchange Danaher shares for common units of Newco. If the split-off exchange offer is not fully subscribed, the additional Newco common units held by Danaher will be distributed in a spin-off on a pro rata basis to Danaher stockholders. Danaher will determine which approach it will take prior to closing the transaction and no decision has been made at this time. At closing, depending on the number of shares of NetScout common stock outstanding, Danaher stockholders will receive approximately 59.5% of the shares of NetScout stock outstanding following the combination. The Transaction is expected to be completed in 2015.

The accompanying combined financial statements present the historical financial position, results of operations, changes in Parent’s equity and cash flows of the Communications Business of Danaher in accordance with GAAP for the preparation of carved-out combined financial statements.

The Communications Business has historically operated as part of Danaher and not as a stand-alone company and has no separate legal status or existence. The financial statements have been derived from Danaher’s historical accounting records and are presented on a carve-out basis. All revenues and costs as well as assets and liabilities directly associated with the business activity of the Communications Business are included as a component of the financial statements. The financial statements also include allocations of certain general,

55

##### Table of Contents

administrative, sales and marketing expenses and cost of sales from Danaher’s corporate office and from other Danaher businesses to the Communications Business and allocations of related assets, liabilities, and Parent’s investment, as applicable. The allocations have been determined on a reasonable basis; however, the amounts are not necessarily representative of the amounts that would have been reflected in the financial statements had the Communications Business been an entity that operated independently of Danaher. Related party allocations are discussed further in Note 16 of the Notes to the Combined Financial Statements for the year ended December 31, 2013.

As part of Danaher, the Communications Business is dependent upon Danaher for all of its working capital and financing requirements as Danaher uses a centralized approach to cash management and financing of its operations. Financial transactions relating to the Communications Business are accounted for through the Parent investment account of the Communications Business. Accordingly, none of Danaher’s cash, cash equivalents or debt at the corporate level has been assigned to the Communications Business in the financial statements.

Net parent investment, which includes retained earnings, represents Danaher’s interest in the recorded net assets of the Communications Business. All significant transactions between the Communications Business and Danaher have been included in the accompanying Combined Financial Statements for the year ended December 31, 2013. Transactions with Danaher are reflected in the accompanying Combined Statements of Changes in Parent’s Equity as “Net transfers from (to) parent” and in the accompanying Combined Balance Sheets within “Net parent investment”.

All significant intercompany accounts and transactions between the operations comprising the Communications Business have been eliminated in the accompanying Combined Financial Statements for the year ended December 31, 2013.

OVERVIEW

General

Please see “—Information on the Communications Business” for a discussion of the Communications Business’ products and services, customer base, and the strategy of the business. The Communications Business is a multinational corporation that serves communication service providers and enterprise networks in all major geographic regions. During 2013, approximately 41% of the Communications Business’ sales were derived from customers outside the United States. As a global business, the Communications Business’ operations are affected by worldwide, regional and industry-specific economic and political factors, as well as technology trends in the markets served. As a result of the Communications Business’ geographic diversity, as well as the breadth of product offerings across a broad segment of communication industry customers, the Communications Business faces a variety of opportunities and challenges, including rapid technological development, the increasing bandwidth requirement of networks, a concentration of customers in North America, the expansion and evolution of opportunities in high-growth markets, trends and costs associated with a global labor force, and competition from local competitors as well as new market entrants. The Communications Business operates in a highly competitive business environment, and the Communications Business’ long-term growth and profitability will depend in particular on its ability to maintain and expand business with existing customers in both North America and on a global basis and to provide continually enhanced technology solutions that address customer needs.

Restructuring Activities

In light of shifts in demand and consistent with the Communications Business’ approach of positioning itself to provide superior products and services to its customers in a cost efficient manner, the Communications Business will, from time to time, initiate actions to improve productivity and reduce cost, incurring severance and other reorganization costs to do so. As a result of these actions, the Communications Business recorded restructuring and other related charges of $5,529,000, $2,340,000 and $3,421,000, in 2013, 2012 and 2011, respectively; of which approximately 91%, 55% and 89%, in each respective year was included in selling general

56

##### Table of Contents

and administrative expenses in the accompanying Combined Statements of Earnings, with the remaining amount charged to cost of sales. In each year, the amounts are predominantly cash charges.

Acquisitions

During 2013, the Communications Business acquired two businesses for total consideration of $74,719,000 in cash, net of cash acquired. The businesses acquired enhanced the technology platforms and research and development capabilities of the Communications Business. The aggregate annual sales of these two businesses at the time of their respective acquisitions, in each case based on the business’ revenues for its last completed fiscal year prior to the acquisition, were approximately $13,100,000.

There were no business acquisitions during the nine months ended September 26, 2014. For a discussion of the Communications Business’ 2012 and 2011 acquisition activity, refer to “Liquidity and Capital Resources—Investing Activities.”

Sales and Backlog

The Communications Business’ total sales decreased $44,706,000, or 7.3%, during the nine months ended September 26, 2014 as compared to the comparable period in 2013. Price increases contributed approximately 1.0% to sales growth during the nine months ended September 26, 2014 as compared to the comparable period in 2013.

Product sales decreased $58,094,000, or 12.7%, during the nine months ended September 26, 2014 as compared to the comparable period in 2013, due primarily to lower product sales of telecommunications network monitoring systems in North America. Certain of the Communications Business’ large customers are in the process of migrating to a next-generation communication network technology infrastructure, and as a result have delayed capital spending on their networks. The Communications Business is actively working with these customers to support this transition, including by increasing research and development investments to bring to market solutions for these customers’ next generation technology requirements. The Communications Business anticipates this technology migration will continue to adversely impact product shipments for the remainder of 2014 and into the first half of 2015. This revenue decline was partially offset by increased product sales from recently acquired businesses which contributed $14,155,000 during the nine months ended September 26, 2014 as compared to the comparable period in 2013 as well as mid-single digit sales growth from existing businesses in enterprise performance management and cyber security products.

Sales of services increased $13,388,000, or 8.7%, during the nine months ended September 26, 2014 as compared to the comparable period in 2013. This sales growth was primarily as a result of continued strong demand for maintenance and service for the Communications Business’ growing installed base of communications network monitoring systems, cyber security systems and growth in new service offerings, including those from recently acquired businesses.

Geographically, sales decreased significantly in North America and grew moderately in Europe, Latin America, the Middle East and Africa during the nine months ended September 26, 2014 as compared to the comparable period in 2013.

Backlog at September 26, 2014 was $299,060,000, a decrease of $58,274,000 as compared to the balance at December 31, 2013. Orders booked during the nine months ended September 26, 2014 decreased $21,190,000 as compared to the comparable period in 2013. These decreases are due primarily to the North American customer capital spending delays described above.

Cost of Sales

Cost of products sales decreased $6,944,000, or 4.8%, during the nine months ended September 26, 2014 as compared to the comparable period in 2013, due primarily to the decrease in demand for communications network monitoring systems, partially offset by increased cost of sales from recent acquisitions of approximately $6,574,000 during the nine months ended September 26, 2014 as compared to the comparable period in 2013.

Cost of services sales increased $4,380,000 or 12.5% during the nine months ended September 26, 2014 and grew faster than service sales due primarily to higher service costs associated with recently acquired businesses which contributed $3,080,000. Cost of sales related to service sales from existing businesses grew at a rate comparable to revenues for the nine months ended September 26, 2014.

Gross Profit

Gross profit declined $42,142,000 or 180 basis points as a percent of sales during the nine months ended September 26, 2014 as compared to the comparable period in 2013.

58

##### Table of Contents

Products gross profit as a percent of products sales decreased 280 basis points during the nine months ended September 26, 2014 as compared to the comparable period in 2013 primarily as a result of North American sales (where margins are typically higher than in other geographies) comprising a lower percentage of total products sales as well as the dilutive impact of recent acquisitions.

Services gross profit as a percent of service sales decreased 80 basis points during the nine months ended September 26, 2014 as compared to the comparable period in 2013 as a result of the dilutive impact of recent acquisitions.

Operating Costs and Other Expenses

Selling, general and administrative expenses increased $6,804,000, or 370 basis points as a percent of sales, during the nine months ended September 26, 2014 as compared to the comparable period in 2013. This increase was due primarily to the following factors:

| • |  | Growth investments to expand the reach of the Communications Business’ direct sales force in developed and emerging markets increased selling, general and administrative expenses by 270 basis points as a percent of sales.

| • |  | Recent acquisitions increased selling, general and administrative expenses by 100 basis points as a percent of sales.

Research and development expenses increased $14,531,000, or 400 basis points as a percent of sales, during the nine months ended September 26, 2014 as compared to the comparable period in 2013. The Communications Business’ investments in new product development, including the next-generation telecommunications monitoring platform that management anticipates will support the customer technology migration described above and expansion of the Communications Business’ cyber security product offerings into advanced persistent threat (“APT”), increased research and development expenses as a percent of sales by 240 basis points during the nine months ended September 26, 2014 as compared to the comparable period of 2013. In addition, recent acquisitions increased research and development expenses as a percent of sales by 160 basis points during the nine months ended September 26, 2014 as compared to the comparable period of 2013.

Amortization of intangible assets decreased $2,334,000 during the nine months ended September 26, 2014 as compared to the comparable period in 2013. Increased amortization associated with intangible assets recorded in connection with the 2013 acquisitions were more than offset by a decrease in amortization driven by the impairment of certain finite-lived intangible assets in the fourth quarter of 2013 that reduced the amortizable asset base by $31,063,000 as well as certain intangible assets associated with the acquisition of Tektronix in 2007 becoming fully amortized during 2013. For more information regarding this impairment charge see “—Results of Operations—Comparison of Results of Operations for the Years Ended December 31, 2013 and December 31, 2012.”

Earnings Before Income Taxes

The Communications Business’ earnings before income taxes declined $61,143,000 during the nine months ended September 26, 2014 as compared to the comparable period in 2013, or 940 basis points as a percent of sales. The reduction in earnings before income taxes as a percent of sales is due to the following factors:

| • |  | The year-over-year decline in sales and incremental year-over-year costs associated with new product development, sales and marketing growth investments, net of incremental year-over-year cost savings associated with the restructuring actions and continuing productivity improvement initiatives taken in 2014 and 2013, negatively impacted earnings before income taxes as a percent of sales by 770 basis points

| • |  | The dilutive impact of recent acquisitions, due primarily to higher research and development costs, negatively impacted earnings before income taxes as a percent of sales by 170 basis points.

Sales and Backlog

The Communications Business’ total sales increased $49,153,000, or 6.3%, during 2013 as compared to 2012. Price increases contributed approximately 1.0% to sales growth during 2013 as compared to 2012.

Product sales grew $28,862,000, or 4.9%, in 2013 as compared to 2012 due to strong demand for telecommunications network monitoring systems, primarily in North America, as carriers continued to expand wireless telecommunication service offerings and increase the capacity of their networks. Increased demand for enterprise network performance management products and enterprise cyber security systems also contributed to growth. Recent acquisitions contributed slightly to product sales growth.

The Communications Business’ service sales increased by $20,291,000, or 10.6%, in 2013 as compared to 2012. This sales growth was primarily a result of continued strong demand for maintenance and service for the Communications Business’ growing installed base (which installed base increased significantly in 2012 as a result of strong year-over-year product sales growth) of communications network monitoring systems, cyber security systems and growth in new service offerings, including those from recently acquired businesses.

Geographically, the Communications Business sales for products and services increased significantly in North America and Latin America during 2013 as compared to 2012, which was offset somewhat by declines in Europe and Asia.

##### Table of Contents

Backlog at December 31, 2013 was $357,334,000, a decrease of $41,070,000 as compared to the balance at December 31, 2012. However, orders booked during 2013 increased $103,494,000 compared to 2012 bookings. Order growth rates can vary significantly due to the size and timing of receipt of customer orders.

Cost of Sales

Cost of products sales increased $5,366,000, or 2.8%, during 2013 as compared to 2012, due primarily to the increase in demand for communications network monitoring systems. Cost of products sales increased at a lower rate than product sales for the period due to the leveraging of certain fixed costs on higher sales levels.

Cost of services sales increased $3,499,000, or 7.9%, during 2013 as compared to 2012 consistent with increased demand for the Communications Business’ service offerings. Cost of services sales increased at a lower rate than services sales for the period due to the leveraging of certain fixed costs on higher sales levels.

Gross Profit

Gross profit increased $40,288,000 or 70 basis points as a percent of sales during 2013 as compared to 2012.

Product gross profit as a percent of product sales increased 60 basis points during 2013 as compared to 2012 primarily as a result of strong demand in North America for communications network management products and resulting fixed cost leverage, offset slightly by the dilutive impact of product sales from recently acquired businesses.

Service gross profit as a percent of service sales increased 60 basis points during 2013 as compared to 2012 primarily as result of strong demand for the Communications Business’ service offerings as discussed above.

Operating Costs and Other Expenses

Selling, general and administrative expenses increased $31,493,000, or 200 basis points as a percent of sales, during 2013 as compared to 2012, due to sales and marketing growth investments to expand the reach of the Communications Business’ direct sales force in developed and emerging markets and the acquisition of VSS Monitoring, Inc. (“VSS”), which contributed 100 basis points to selling, general and administrative expenses as a percent of sales during 2013 as compared to 2012.

Research and development expenses increased $16,681,000, or 100 basis points as a percent of sales, during 2013 as compared to 2012. This increase was due primarily to investments in new product development, including the next-generation telecommunications monitoring platform that management anticipates will support the customer technology migration described above and expansion of the Communications Business’ cyber security offering into APT as well as continued product development for recently acquired businesses.

Amortization of intangibles increased $2,334,000 during 2013 as compared to 2012 primarily due to the amortization of intangible assets from the acquisition of VSS in the second quarter 2012 and to a lesser extent from business acquisitions in 2013.

The Communications Business recorded an impairment charge of $31,063,000 in 2013 to reduce certain customer relationship assets associated with an acquisition to their fair value. These customer relationship assets were deemed to be impaired because, as of December 31, 2013, orders and financial results of the business had not materialized according to the original expectations of the Communications Business as of the date of acquisition. For additional information regarding the impairment charge see Note 6 to the Combined Financial Statements for the year ended December 31, 2013.

The Communications Business’ earnings before income taxes declined $41,283,000 during 2013 as compared to 2012, and as a percent of sales, declined from 20.1% of sales in 2012 to 14.0% of sales in 2013. The reduction in earnings before income taxes as a percent of sales is due to the following factors:

| • |  | The dilutive impact of recent acquisitions negatively impacted earnings before income taxes by 220 basis points.

| • |  | Intangible asset impairment negatively impacted earnings before income taxes by 370 basis points.

| • |  | The year-over-year increase in sales, and incremental year-over-year cost savings associated with the restructuring actions and continuing productivity improvement initiatives taken in 2013 and 2012, offset by incremental year-over-year costs associated with new product development, sales and marketing growth investments negatively impacted earnings before income taxes as a percent of sales by 20 basis points.

Sales and Backlog

The Communications Business’ total sales increased $116,459,000, or 17.4%, during 2012 as compared to 2011. Price increases contributed approximately 1.0% to sales growth during 2012 as compared to 2011.

##### Table of Contents

Product sales increased $110,988,000, or 22.9%, during 2012 as compared to 2011 due to robust demand for the Communications Business’ telecommunications network monitoring systems, primarily in North America, as well as increased demand for cyber security systems. The acquisition of VSS during the second quarter of 2012 also contributed $29,143,000 to product sales.

Sales of the Communications Business’ services increased by $5,471,000, or 2.9%, in 2012 as compared to 2011. This sales growth was primarily a result of continued demand for maintenance and service for the Communications Business’ growing installed base of communications network monitoring systems, cyber security systems and growth in new service offerings, including from the acquisition of VSS which contributed $1,020,000 to service sales in 2012.

Geographically, the Communications Business sales for products and services increased significantly in North America, Europe and Asia during 2012 as compared to 2011. Growth was moderate in Latin America during 2012 as compared to 2011.

Backlog at December 31, 2012 was approximately $398,404,000, a decrease of $95,411,000 as compared to the balance at December 31, 2011. Orders booked during 2012 decreased $66,034,000 as compared to 2011. This decrease is due primarily to the timing of orders received from large telecommunications network providers in 2011.

Cost of Sales

Cost of products sales increased $5,366,000, or 2.8%, during 2013 as compared to 2012, due primarily to the increase in demand for communications network monitoring systems. Cost of products sales increased at a lower rate than product sales for the period due to the leveraging of certain fixed costs on higher sales levels.

Cost of services sales increased $3,499,000, or 7.9%, during 2013 as compared to 2012 consistent with increased demand for the Communications Business’ service offerings. Cost of services sales increased at a lower rate than services sales for the period due to the leveraging of certain fixed costs on higher sales levels.

Gross Profit

Gross profit increased $95,096,000 or 200 basis points as a percent of sales in 2012 as compared to 2011.

Product gross profit as a percent of product sales increased 290 basis points during 2012 as compared to 2011 as a result of increased leverage due to strong demand for communications network management products in North America and the impact of acquisitions in 2012, which had higher overall gross profit margins than the existing businesses.

Service gross profit as a percent of service sales increased 70 basis points during 2012 as compared to 2011 primarily as result of increased leverage due to strong demand for the Communications Business’ service offerings as discussed above.

Operating Costs and Other Expenses

Selling, general and administrative expenses increased $28,207,000 during 2012 as compared to 2011, due to sales and marketing growth investments to expand the reach of the Communications Business’ direct sales force in developed and emerging markets and the acquisition of VSS, which added approximately $14,022,000 to selling, general and administrative expenses during 2012. Selling, general and administrative expenses decreased 130 basis points as a percent of sales during 2012 as compared to 2011 due to improved leverage of expenses over a growing sales base.

Research and development expenses increased $18,974,000 during 2012 as compared to 2011. This increase was due primarily to investments in new product development, and the acquisition of VSS, which added approximately $6,451,000 to research and development expenses during 2012. Research and development expenses were essentially flat as a percent of sales during 2012 as compared to 2011.

##### Table of Contents

Amortization of intangibles increased $1,703,000 during 2012 as compared to 2011 primarily due to the amortization of intangible assets from the acquisition of VSS in the second quarter 2012.

The Communications Business recorded an impairment charge of $4,947,000 in 2011 to reduce the value of certain customer relationship and technology assets arising from a prior business acquisition to their estimated fair value. These intangible assets were deemed to be impaired because as of December 31, 2011, financial results of the acquired business to which these assets relate had lagged behind the original expectations of the Communications Business as of the date of acquisition. For additional information regarding the impairment charge see Note 6 to the Combined Financial Statements for the year ended December 31, 2013.

Earnings Before Income Taxes

The Communications Business’ earnings before income taxes increased $51,159,000 during 2012 as compared to 2011, and as a percent of sales increased from 15.9% of sales in 2011 to 20.1% of sales in 2012. The increase in earnings before income taxes as a percent of sales is due to the following factors:

| • |  | The year-over-year increase in sales and incremental year-over-year cost savings associated with the restructuring actions and continuing productivity improvement initiatives taken in 2012 and 2011, partially offset by incremental year-over-year costs associated with new product development and sales and marketing growth investments positively impacted earnings before income taxes as a percent of sales by 340 basis points.

| • |  | The impact of recent acquisitions positively impacted earnings before income taxes by 10 basis points.

| • |  | The intangible asset impairment recorded in 2011 positively impacted earnings before income taxes by 70 basis points.

INCOME TAXES

General

The Communications Business’ domestic and international earnings are included in tax returns filed by Danaher. The Communications Business accounts for income taxes under the separate returns method. Under this approach, income tax expense and deferred tax assets and liabilities are determined as if the Communication Business were filing separate returns. The Communications Business records the tax effect of discrete items in the period in which they occur.

The Communications Business’ effective tax rate can be affected by changes in the mix of earnings in countries with differing statutory tax rates (including as a result of business acquisitions and dispositions), changes in the valuation of deferred tax assets and liabilities, accruals related to contingent tax liabilities and period-to-period changes in such accruals, the results of audits and examinations of previously filed tax returns (as discussed below), the expiration of statutes of limitations, the implementation of tax planning strategies, tax rulings, court decisions, settlements with tax authorities and changes in tax laws.

As part of Danaher, the amount of income taxes the Communications Business pays is subject to ongoing audits by federal, state and foreign tax authorities, which often result in proposed assessments. Management performs a comprehensive review of its global tax positions on a quarterly basis. Based on these reviews, the results of discussions and resolutions of matters with certain tax authorities, tax rulings and court decisions, and the expiration of statutes of limitations, reserves for contingent tax liabilities are accrued or adjusted as necessary.

Comparison of the Nine Months Ended September 26, 2014 and September 27, 2013

The Communications Business’ effective tax rate for the nine months ended September 26, 2014 and September 27, 2013, was 31.2% and 28.7%, respectively. The effective tax rate for 2014 and 2013 is lower than the U.S. federal statutory rate of 35% due principally to tax benefits of the Domestic Production Activities

##### Table of Contents

Deduction, partially offset by state income taxes. In addition, the effective tax rate in 2013 is also lower due to the research and experimentation credit, which includes the benefit from the retroactive reinstatement of the credit for the year-ended December 31, 2012 by the American Tax Relief Act of 2012.

Comparison of the Years Ended December 31, 2013 and December 31, 2012

The Communications Business’ effective tax rate for 2013 and 2012, was 28.1% and 34.3%, respectively. The Communications Business’ effective tax rate for each of 2013 and 2012 is lower than the U.S. federal statutory rate of 35% due principally to tax benefits of the Domestic Production Activities Deduction and the lapse of certain statutes of limitation with respect to uncertain tax positions, partially offset by state income taxes. For the year ended December 31, 2013, the effective tax rate is also lower due to the research and experimentation credit, which includes the 2013 benefit from the retroactive reinstatement of the credit for the year ended December 31, 2012 by the American Tax Relief Act of 2012.

Comparison of the Years Ended December 31, 2012 and December 31, 2011

The Communications Business’ effective tax rate for 2012 and 2011, was 34.3% and 30.3%, respectively. The Communications Business’ effective tax rate for each of 2012 and 2011 is lower than the U.S. federal statutory rate of 35% due principally to tax benefits of the Domestic Production Activities Deduction and the lapse of certain statutes of limitation with respect to uncertain tax positions, partially offset by state income taxes. For the year ended December 31, 2011 the effective tax rate is also lower due to the research and experimentation credit which was effective for 2011 but lapsed in 2012. This credit was reinstated in 2013 by the American Tax Relief Act of 2012.

INFLATION

The effect of inflation on the Communications Business’ revenues and net earnings was not significant in the years ended December 31, 2013, 2012 or 2011 nor in the nine months ended September 26, 2014 and September 27, 2013.

RISK MANAGEMENT

The Communications Business is exposed to market risk from changes in foreign currency exchange rates, credit risk, and commodity prices, each of which could impact its financial statements. The Communications Business generally addresses its exposure to these risks through its normal operating and financing activities.

Currency Exchange Rate Risk

The Communications Business faces transactional exchange rate risk from transactions with customers in countries outside the United States and from intercompany transactions between affiliates. Transactional exchange rate risk arises from the purchase and sale of goods and services in currencies other than the Communications Business’ functional currency or the functional currency of an applicable subsidiary. The Communications Business also faces translational exchange rate risk related to the translation of financial statements of foreign operations into U.S. dollars, the Communications Business’ functional currency. Costs incurred and sales recorded by subsidiaries operating outside of the United States are translated into U.S. dollars using exchange rates effective during the respective period. As a result, the Communications Business is exposed to movements in the exchange rates of various currencies against the U.S. dollar, particularly the Euro. Therefore, when the Euro strengthens or weakens against the U.S. dollar, operating profits are increased or decreased, respectively. The effect of a change in currency exchange rates on the Communications Business’ net investment in international subsidiaries is reflected in the accumulated other comprehensive income (loss) component of Parent’s equity. A 10% depreciation in the Euro to the U.S. dollar at September 26, 2014 would have resulted in a reduction of parent’s equity of approximately $5,600,000.

65

##### Table of Contents

The impact of currency exchange rates on reported sales during the nine months ended September 26, 2014 and the years ended December 31, 2013, 2012 and 2011 was negligible.

If the exchange rates in effect as of September 26, 2014 were to prevail throughout 2014, currency exchange rates would have a negligible impact on full-year 2014 estimated sales relative to the Communications Business’ performance in 2013. Any weakening of the U.S. dollar against other major currencies, particularly the Euro, would further positively impact the Communications Business’ sales and results of operations. Any strengthening of the U.S. dollar against other major currencies, particularly the Euro, would adversely impact the Communications Business’ sales and results of operations on an overall basis.

As part of Danaher, the Communications Business has generally accepted the exposure to exchange rate movements without using derivative financial instruments to manage this risk. Both positive and negative movements in currency exchange rates against the U.S. dollar will therefore continue to affect the reported amount of sales, profit, and assets and liabilities in the Communications Business’ financial statements.

Credit Risk

The Communications Business is exposed to potential credit losses in the event of nonperformance by counterparties to its financial instruments. Financial instruments that potentially subject the Communications Business to credit risk consist of receivables from customers.

Sales to the Communications Business’ largest two customers were 31% of total sales during the nine months ended September 26, 2014, 38% of total sales during the nine months ended September 27, 2013, 36% of total sales in 2013, 33% of total sales in 2012, and 33% in of total sales in 2011. No other individual customer accounted for more than 10% of combined sales during these periods. Accounts receivable from these customers was 18% of total receivables as of September 26, 2014, 11% as of December 31, 2013, and 9% at December 31, 2012.

The Communications Business’ management performs credit evaluations of their customers’ financial conditions as appropriate and also obtain collateral or other security when appropriate.

LIQUIDITY AND CAPITAL RESOURCES

As part of Danaher, the Communications Business is dependent upon Danaher for all of its working capital and financing requirements as Danaher uses a centralized approach to cash management and financing of its operations. Financial transactions relating to the Communications Business are accounted for through the Parent investment account of the Communications Business. Accordingly, none of Danaher’s cash, cash equivalents or debt at the corporate level has been assigned to the Communications Business in the financial statements. During the years ended December 31, 2013 and 2011, the nine months ended September 26, 2014 and September 27, 2013, the Communications Business generated sufficient cash from operating activities to fund its capital spending and acquisitions. During the year ended December 31, 2012, Danaher provided funding to the Communications Business to support the Communications Business’ investing activities.

Operating cash flows decreased $20,305,000 during the nine months ended September 26, 2014 as compared to the comparable period in 2013, principally due to lower net earnings partially offset by higher levels of customer deposits on future product and service deliveries. Cash used in investing activities decreased $10,600,000 during the nine months ended September 26, 2014 as compared to the comparable period in 2013, as there were no acquisitions of businesses in the nine months ended September 26, 2014. Cash used in financing activities decreased $9,705,000 during the nine months ended September 26, 2014 as compared to the comparable period in 2013, as the Communications Business transferred less cash to Danaher as a result of the decrease in operating cash flows and the payment in the nine months ended September 26, 2014 of an earn-out liability related to a recent acquisition.

Operating cash flows decreased $69,170,000 during 2013 as compared to 2012 principally due to lower net earnings and the timing of customer deposits received in 2012. Cash used in investing activities decreased $113,468,000 during 2013 as compared to 2012, as cash paid for acquisitions decreased by $114,419,000.

Contractual Obligations

The following table sets forth, by period due or year of expected expiration, as applicable, a summary of the Communications Business’ contractual obligations as of December 31, 2013 under (1) leases, (2) purchase obligations and (3) other long-term liabilities reflected on the Communications Business’ balance sheet under GAAP. The amounts presented in the table below do not reflect $5,952,000 of gross unrecognized tax benefits, the timing of which is uncertain. Refer to Note 12 to the Combined Financial Statements for the year ended December 31, 2013 for additional information on unrecognized tax benefits.

(a) | As described in Note 10 to the Combined Financial Statements for the year ended December 31, 2013, certain leases require the Communications Business to pay real estate taxes, insurance, maintenance and other operating expenses associated with the leased premises. These future costs are not included in the schedule above.

(b) | Consist of agreements to purchase goods or services that are enforceable and legally binding on the Communications Business and that specify all significant terms, including fixed or minimum quantities to be purchased, fixed, minimum or variable price provisions and the approximate timing of the transaction.

(c) | Primarily consist of obligations for earn-out and indemnification obligations, self-insurance and litigation claims, pension obligations, deferred tax liabilities (excluding unrecognized tax benefits) and deferred compensation obligations. The timing of cash flows associated with these obligations is based upon management’s estimates over the terms of these arrangements and is largely based upon historical experience.

Off-Balance Sheet Arrangements

In the normal course of business, the Communications Business periodically enters into agreements that require it to indemnify customers, suppliers or other business partners for specific risks, such as claims for injury or property damage arising out of the Communications Business’ products or services or claims alleging that Communications Business products, services or software infringe third party intellectual property. Historically, the Communications Business has not experienced significant losses on these types of indemnification obligations.

Legal Proceedings

Please refer to Note 11 to the Combined Financial Statements for the year ended December 31, 2013 for information regarding certain litigation matters.

In addition to the litigation matters noted under “— Information on the Communications Business” the Communications Business is, from time to time, subject to a variety of litigation and other proceedings incidental to its business, including lawsuits involving claims for damages arising out of the use of the Communications Business’ products, software and services, claims relating to intellectual property matters, employment matters, commercial disputes, and personal injury as well as regulatory investigations or enforcement. The Communications Business may also become subject to lawsuits as a result of past or future acquisitions or as

68

##### Table of Contents

a result of liabilities retained from, or representations, warranties or indemnities provided in connection with divested businesses. Some of these lawsuits may include claims for punitive and consequential as well as compensatory damages. Based upon the Communications Business’ experience, current information and applicable law, it does not believe that these proceedings and claims will have a material adverse effect on its financial position, results of operations or cash flows.

While Danaher maintains workers compensation, property, cargo, automobile, crime, fiduciary, product, general liability, and directors’ and officers’ liability insurance on behalf of the Communications Business that cover a portion of these claims, this insurance may be insufficient or unavailable to cover such losses. In addition, while the Communications Business believes it is entitled to indemnification from third parties for some of these claims, these rights may also be insufficient or unavailable to cover such losses. Danaher maintains third party insurance policies on behalf of the Communications Business up to certain limits to cover certain liability costs in excess of predetermined retained amounts. For general liability risk (which includes product liability) and most other insured risks, Danaher purchases outside insurance coverage only for severe losses (stop loss insurance) and reserves must be established and maintained with respect to amounts within the self-insured retention.

In accordance with accounting guidance, the Communications Business records a liability in the combined financial statements for loss contingencies when a loss is known or considered probable and the amount can be reasonably estimated. If the reasonable estimate of a known or probable loss is a range, and no amount within the range is a better estimate than any other, the minimum amount of the range is accrued. If a loss does not meet the known or probable level but is reasonably possible and a loss or range of loss can be reasonably estimated, the estimated loss or range of loss is disclosed. These reserves consist of specific reserves for individual claims and additional amounts for anticipated developments of these claims as well as for incurred but not yet reported claims. The specific reserves for individual known claims are quantified with the assistance of legal counsel and outside risk insurance professionals where appropriate. In addition, outside risk insurance professionals assist in the determination of reserves for incurred but not yet reported claims through evaluation of the Communications Business’ specific loss history, actual claims reported, and industry trends among statistical and other factors. Reserve estimates are adjusted as additional information regarding a claim becomes known. While the Communications Business actively pursues financial recoveries from insurance providers, it does not recognize any recoveries until realized or until such time as a sustained pattern of collections is established related to historical matters of a similar nature and magnitude. If the risk insurance reserves established with respect to the Communications Business are inadequate, the Communications Business would be required to incur an expense equal to the amount of the loss incurred in excess of the reserves, which would adversely affect the Communications Business’ net earnings.

In addition, the Communications Business’ operations are subject to environmental laws and regulations in the jurisdictions in which they operate, which impose limitations on the discharge of pollutants into the ground, air and water and establish standards for the use, generation, treatment, storage and disposal of hazardous and non-hazardous wastes. Certain of the Communications Business’ operations involve the handling, manufacturing, use or sale of substances that are or could be classified as hazardous materials within the meaning of applicable laws. The Communications Business must also comply with various health and safety regulations in both the United States and abroad in connection with its operations. Compliance with these laws and regulations has not had and, based on current information and the applicable laws and regulations currently in effect, is not expected to have a material adverse effect on the Communications Business’ capital expenditures, earnings or competitive position, and the Communications Business does not anticipate material capital expenditures for environmental control facilities.

For a discussion of additional risks related to legal proceedings, please refer to “Item 1A. Risk Factors.”

CRITICAL ACCOUNTING ESTIMATES

Management’s discussion and analysis of the Communications Business’ financial condition and results of operations is based upon the Communications Business’ Combined Financial Statements, which have been prepared in accordance with accounting principles generally accepted in the United States for the preparation of carved-out, combined financial statements. The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. The Communications Business bases these estimates and judgments on historical experience, the current economic environment and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ materially from these estimates and judgments.

The Communications Business believes the following accounting estimates are most critical to an understanding of its financial statements. Estimates are considered to be critical if they meet both of the following criteria: (1) the estimate requires assumptions about material matters that are uncertain at the time the estimate is made, and (2) material changes in the estimate are reasonably likely from period to period. For a detailed discussion on the application of these and other accounting estimates, refer to Note 2 in the Communications Business’ Combined Financial Statements for the year ended December 31, 2013.

Accounts Receivable— The Communications Business maintains allowances for doubtful accounts to reflect probable credit losses inherent in its portfolio of receivables. Determination of the allowances requires management to exercise judgment about the timing, frequency and severity of credit losses that could materially affect the allowances for doubtful accounts and, therefore, net income. The allowances for doubtful accounts represent management’s best estimate of the credit losses expected from the Communications Business’ trade accounts, contract and finance receivable portfolios. The level of the allowances is based on many quantitative and qualitative factors including historical loss experience by receivable type, portfolio duration, delinquency trends, economic conditions and credit risk quality. The Communications Business regularly performs detailed reviews of its accounts receivable portfolio to determine if an impairment has occurred and to assess the adequacy of the allowances. If the financial condition of the Communications Business’ customers were to deteriorate with a severity, frequency and/or timing different from the Communications Business’ assumptions, additional allowances would be required and the Communications Business’ financial statements would be adversely impacted.

Inventories— The Communications Business records inventory at the lower of cost or market value. The Communications Business estimates the market value of its inventory based on assumptions of future demand and related pricing. Estimating the market value of inventory is inherently uncertain because levels of demand, technological advances and pricing competition in many of the Communications Business’ markets can fluctuate significantly from period to period due to circumstances beyond the Communications Business’ control. If actual market conditions are less favorable than those projected by management, the Communications Business could be required to reduce the value of its inventory, which would adversely impact the Communications Business’ financial statements.

Acquired Intangibles— The Communications Business’ acquisitions typically result in the recognition of goodwill, in-process research and development and other intangible assets, which affect the amount of future period amortization expense and possible impairment charges that the Communications Business may incur. Refer to Notes 2, 3 and 6 in the Communications Business’ Combined Financial Statements for the year ended December 31, 2013 for a description of the Communications Business’ policies relating to goodwill, acquired intangibles and acquisitions.

In performing its goodwill impairment testing, the Communications Business estimates the fair value of its reporting units primarily using a market based approach. The Communications Business estimates fair value based on appropriate multiples of sales or earnings before interest, taxes, depreciation and amortization (“EBITDA”) determined by current trading market multiples of earnings and/or sales for companies operating in

70

##### Table of Contents

businesses similar to each of the Communications Business’ reporting units, in addition to recent market available sale transactions of comparable businesses. In evaluating the estimates derived by the market based approach, management makes judgments about the relevance and reliability of the multiples by considering factors unique to its reporting units, including operating results, business plans, economic projections, anticipated future cash flows, and transactions and marketplace data as well as judgments about the comparability of the market proxies selected. In certain circumstances the Communications Business also estimates fair value utilizing a discounted cash flow analysis (i.e., an income approach) in order to validate the results of the market approach. The discounted cash flow model requires judgmental assumptions about projected revenue growth, future operating margins, discount rates and terminal values. There are inherent uncertainties related to these assumptions and management’s judgment in applying them to the analysis of goodwill impairment.

As of December 31, 2013, the Communications Business had four reporting units for goodwill impairment testing. Reporting units resulting from recent acquisitions generally present the highest risk of impairment. Management believes the impairment risk associated with these reporting units decreases as these businesses are integrated into the Communications Business and better positioned for potential future earnings growth. The carrying value of the goodwill included in each individual reporting unit ranges from $59,330,000 to $422,475,000. The Communications Business’ annual goodwill impairment analysis in 2013 indicated that in all instances, the fair values of the Communications Business’ reporting units exceeded their carrying values and consequently did not result in an impairment charge.

The Communications Business reviews identified intangible assets for impairment whenever events or changes in circumstances indicate that the related carrying amounts may not be recoverable. The Communications Business also tests intangible assets with indefinite lives at least annually for impairment. Determining whether an impairment loss occurred requires a comparison of the carrying amount to the sum of undiscounted cash flows expected to be generated by the asset. These analyses require management to make judgments and estimates about future revenues, expenses, market conditions and discount rates related to these assets.

As a result of these impairment analyses, the Communications Business recorded impairment charges of $31,063,000 in 2013 and $4,947,000 in 2011 related to the value of customer relationship and technology intangible assets. There were no impairments recorded in 2012. The 2013 impairment charge was recorded to reduce the value of certain customer relationship assets to their estimated fair value. These customer relationship assets were deemed to be impaired because as of December 31, 2013, orders and financial results of the acquired business to which these assets relate had not materialized according to the original expectations of the Communications Business as of the date of acquisition. The 2011 impairment charge was recorded to reduce the value of certain customer relationship and technology assets to their estimated fair value. These intangible assets were deemed to be impaired because as of December 31, 2011, financial results of the acquired business to which these assets relate had lagged behind the original expectations of the Communications Business as of the date of acquisition.

If actual results are not consistent with management’s estimates and assumptions, goodwill and other intangible assets may be overstated and a charge would need to be taken against net earnings which would adversely affect the Communications Business’ financial statements.

Contingent Liabilities— As discussed above under “—Liquidity and Capital Resources - Legal Proceedings”, the Communications Business is, from time to time, subject to a variety of litigation and similar contingent liabilities incidental to its business (or the business operations of previously owned entities). The Communications Business recognizes a liability for any contingency that is known or probable of occurrence and reasonably estimable. These assessments require judgments concerning matters such as litigation developments and outcomes, the anticipated outcome of negotiations, the number of future claims and the cost of both pending and future claims. In addition, because most contingencies are resolved over long periods of time, liabilities may change in the future due to various factors, including those discussed above under “—Liquidity and Capital Resources—Legal Proceedings”. If the reserves established by the Communications Business with respect to

71

##### Table of Contents

these contingent liabilities are inadequate, the Communications Business would be required to incur an expense equal to the amount of the loss incurred in excess of the reserves, which would adversely affect the Communications Business’ financial statements.

In connection with acquisitions, the Communications Business may enter into post-closing financial arrangements such as purchase price adjustments, earn-out obligations and indemnification obligations. These obligations are recorded at their fair value at the time of acquisition and require management to make judgments and estimates about the ultimate settlement amount. While the Communications Business believes it has made reasonable estimates and assumptions to calculate the fair value of these obligations, if actual results are not consistent with management’s estimates and assumptions, these obligations may be understated and a charge would need to be taken against net earnings.

Revenue Recognition— The Communications Business derives revenues from the sale of products and services. Refer to Note 2 to the Communications Business’ Combined Financial Statements for the year ended December 31, 2013 for a description of the Communications Business’ revenue recognition policies.

Certain commercial agreements contain multiple elements or non-standard terms and conditions. As a result, judgment is sometimes required to determine the appropriate accounting, including whether the deliverables specified in these agreements should be treated as separate units of accounting for revenue recognition purposes, and, if so, how the consideration should be allocated among the elements and when to recognize revenue for each element.

The Communications Business allocates revenue to each element in the contractual arrangement based on a selling price hierarchy that, in some instances, may require the Communications Business to estimate the selling price of certain deliverables that are not sold separately or where third party evidence of pricing is not observable. When it is required to estimate selling prices, the Communications Business considers relevant internal and external market and entity-specific factors including the relative technological advancement of the product offering, the historical pricing practices and profit objectives and the geographic region and nature of the customer. The Communications Business monitors, on at least an annual basis, its selling price estimates to ensure they are within a sufficiently narrow range within the geographies and customer classes served. Estimates of selling prices impact the amount and timing of revenue recognized in multiple element arrangements. If the Communications Business’ judgments regarding revenue recognition prove incorrect, the Communications Business’ revenues in particular periods may be adversely affected.

Corporate Allocations— The Communications Business has historically operated as part of Danaher and not as a stand-alone company. Accordingly, certain shared costs have been allocated to the Communications Business and are reflected as expenses in the accompanying financial statements. Management considers the allocation methodologies used to be reasonable and appropriate reflections of the related expenses attributable to the Communications Business for purposes of the carve-out financial statements; however, the expenses reflected in these financial statements may not be indicative of the actual expenses that would have been incurred during the periods presented if the Business had operated as a separate stand-alone entity. In addition, the expenses reflected in the financial statements may not be indicative of expenses that will be incurred in the future by the Communications Business.

Stock-Based Compensation— For a description of the Communications Business’ stock-based compensation accounting practices, refer to Note 13 to the Communications Business’ Combined Financial Statements for the year ended December 31, 2013. Determining the appropriate fair value model and calculating the fair value of stock-based payment awards require subjective assumptions, including the expected life of the awards, stock price volatility and expected forfeiture rate. The assumptions used in calculating the fair value of stock-based payment awards represent the Communications Business’ best estimates, but these estimates involve inherent uncertainties and the application of management judgment. If actual results are not consistent with management’s assumptions and estimates, the Communications Business’ equity-based compensation expense could be materially different in the future.

Pension — For a description of the Communications Business’ pension benefit accounting practices, refer to Note 9 in the Communications Business’ Combined Financial Statements for the year ended December 31, 2013. Calculations of the amount of pension costs and obligations depend on the assumptions used in the actuarial valuations, including assumptions regarding discount rates, expected return on plan assets, rates of salary increases, mortality rates, and other factors. If the assumptions used in calculating pension costs and obligations are incorrect or if the factors underlying the assumptions change (as a result of differences in actual experience, changes in key economic indicators or other factors) the Communications Business’ financial statements could be materially affected.

The Communications Business’ pension plan assets consist of various insurance contracts, equity and debt securities as determined by the administrator of each plan. The estimated long-term rate of return for the plans was determined on a plan by plan basis based on the nature of the plan assets and ranged from 4% to 6%. If the expected long-term rate of return on plan assets for 2013 was reduced by 50 basis points, pension expense for the plans for 2013 would have increased $6,500 ($4,600 on an after-tax basis).

During 2014, the Communications Business’ cash contribution requirements for its defined benefit pension plans are expected to be approximately $93,000. The ultimate amounts to be contributed depend upon, among other things, legal requirements, underlying asset returns, the plan’s funded status, the anticipated tax deductibility of the contribution, local practices, market conditions, interest rates and other factors.

Income Taxes— For a description of the Communications Business’ income tax accounting policies, refer to Notes 2 and 12 of the Communications Business’ Combined Financial Statements for the year ended December 31, 2013. The Communications Business establishes valuation allowances for its deferred tax assets if it is more likely than not that some or all of the deferred tax asset will not be realized which requires management to make judgments and estimates regarding: (1) the timing and amount of the reversal of taxable temporary differences, (2) expected future taxable income, and (3) the impact of tax planning strategies. Future changes to tax rates would also impact the amounts of deferred tax assets and liabilities and could have an adverse impact on the Communications Business’ financial statements.

The Communications Business provides for unrecognized tax benefits when, based upon the technical merits, it is “more-likely-than-not” that an uncertain tax position will not be sustained upon examination. Judgment is required in evaluating tax positions and determining income tax provisions. The Communications Business re-evaluates the technical merits of its tax positions and may recognize an uncertain tax benefit in certain circumstances, including when: (i) a tax audit is completed; (ii) applicable tax laws change, including a tax case ruling or legislative guidance; or (iii) the applicable statute of limitations expires.

An increase in the nominal tax rate of 1% would have resulted in an additional income tax provision for continuing operations for the fiscal year ended December 31, 2013 of $1,166,000.

NEW ACCOUNTING STANDARDS

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606), which impacts virtually all aspects of an entity’s revenue recognition. The core principle of the new standard is that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard is effective for annual reporting periods beginning after December 15, 2016. Management has not yet completed its assessment of the impact of the new standard, including possible transition alternatives, on the Communications Business’ financial statements.

| communications by reporting the following non-GAAP measures: non-GAAP revenue, non-GAAP net income, non-GAAP free cash flows and non-GAAP net income per diluted share. Non-GAAP revenue eliminates the GAAP effects of acquisitions by adding back revenue related to deferred revenue revaluation, and, for the fiscal year ended March 31, 2011, eliminates the revenue impact of recently adopted accounting guidance. Non-GAAP net income includes the foregoing adjustment and also removes expenses related to the amortization of acquired intangible assets, share-based compensation, restructuring, certain expenses relating to acquisitions including compensation for post-combination services, business development charges and loss on early extinguishment of debt, net of related income tax effects. Non-GAAP diluted net income per share also excludes these expenses as well as the related impact of all these adjustments on the provision for income taxes. Non-GAAP free cash flow is operating cash flow less outflows for PP&E and intangibles.

These non-GAAP measures are not in accordance with GAAP, should not be considered an alternative for measures prepared in accordance with GAAP (revenue, net income and diluted net income per share), and may have limitations in that they do not reflect all our results of operations as determined in accordance with GAAP. These non-GAAP measures should only be used to evaluate our results of operations in conjunction with the corresponding GAAP measures. The presentation of non-GAAP information is not meant to be considered superior to, in isolation from, or as a substitute for results prepared in accordance with GAAP.

NetScout management believes these non-GAAP financial measures enhance the reader’s overall understanding of NetScout’s current financial performance and its prospects for the future by providing a higher degree of transparency for certain financial measures and providing a level of disclosure that helps investors understand how NetScout plans and measures its business. NetScout believes that providing these non-GAAP measures affords investors a view of NetScout’s operating results that may be more easily compared to its peer companies and also enables investors to consider NetScout’s operating results on both a GAAP and non-GAAP basis during and following the integration period of NetScout’s acquisitions. Presenting the GAAP measures on their own may not be indicative of our core operating results. Furthermore, management believes that the presentation of non-GAAP measures when shown in conjunction with the corresponding GAAP measures provide useful information to management and investors regarding present and future business trends relating to NetScout’s financial condition and results of operations.

Unaudited Pro Forma Combined Consolidated Information of NetScout and the Communications Business

The following unaudited pro forma combined financial information was prepared using the historical consolidated financial statements of NetScout and the combined financial statements of the Communications Business. The unaudited pro forma combined financial information, including the notes thereto, should be read in conjunction with the following historical financial statements and accompanying notes for the applicable periods, which are incorporated by reference or included in this document:

| • |  | NetScout’s audited consolidated financial statements for the fiscal year ended March 31, 2014 (fiscal year 2014) included in NetScout’s Annual Report on Form 10-K which was filed with the SEC on May 20, 2014 (incorporated by reference);

| • |  | NetScout’s unaudited consolidated financial statements for the six month period ended September 30, 2014 included in NetScout’s Quarterly Report on Form 10-Q which was filed with the SEC on October 28, 2014 (incorporated by reference);

| • |  | The Communications Business’ audited combined financial statements for the year ended December 31, 2013 included in this document; and

| • |  | The Communications Business’ unaudited condensed combined financial statements for the nine month period ended September 26, 2014 included in this document.

The accompanying unaudited pro forma combined financial statements give pro forma effect to the acquisition of all of the outstanding common units of the Communications Business by NetScout assuming an equity consideration of $2,380.6 million, paid in NetScout Systems, Inc. common stock based on the closing price of NetScout common stock as of November 21, 2014 (the “Communications Business Acquisition”).

NetScout’s fiscal year 2014 ended on March 31, 2014. The Communications Business’ corresponding fiscal year ended on December 31, 2013. The unaudited interim pro forma combined balance sheet assumes that the Communications Business Acquisition took place on September 30, 2014 and combines NetScout’s historical consolidated balance sheet as of September 30, 2014 with the Communications Business’ historical unaudited combined condensed balance sheet as of September 26, 2014 (communications business interim period end) and applies pro forma adjustments to the resulting amounts.

The unaudited pro forma combined statements of operations for the fiscal year ended March 31, 2014, and the six month period ended September 30, 2014 assume that the Communications Business Acquisition took place on the first day of fiscal year 2014 (April 1, 2013). The unaudited pro forma combined statement of operations for the year ended March 31, 2014 combines NetScout’s historical consolidated statement of operations for the fiscal year 2014 with the Communications Business’ historical combined statement of operations for the fiscal year ended December 31, 2013 and applies pro forma adjustments to the resulting amounts. The unaudited pro forma combined statement of operations for the six months ended September 30, 2014 combines NetScout’s historical consolidated statement of operations for the six months ended September 30, 2014 with the Communications Business’ historical unaudited combined condensed statement of operations for the six months fiscal period ended September 26, 2014 and applies pro forma adjustments to the resulting amounts.

The unaudited pro forma combined financial information has been prepared by NetScout management and is based on the estimates and assumptions set forth in the notes to such information. The unaudited pro forma combined financial information is being presented for illustrative purposes only and, therefore, is not necessarily indicative of the consolidated results of operations or financial position that might have been achieved by the combined company for the dates or periods indicated, nor is it necessarily indicative of the results of operations or financial position of the combined company that may occur in the future.

##### Table of Contents

The unaudited pro forma combined financial information has been prepared using the acquisition method of accounting for business combinations under accounting principles generally accepted in the United States, or GAAP. The unaudited pro forma adjustments related to the Communications Business Acquisition are preliminary and do not reflect the final purchase price or final allocation of the excess of the purchase price over the net book value of the net assets of the Communications Business. The final purchase price and allocation of the purchase price will be based on the fair value of assets and liabilities that exist at the closing date of the Communications Business Acquisition. Accordingly, the pro forma purchase price adjustments are preliminary and are subject to further adjustments as additional information becomes available and additional analysis is performed. Upon closing of the acquisition, final valuations will be performed. The completion of the valuation, accounting for the Communications Business Acquisition and the allocation of the purchase price may be different than that of the amounts reflected in the pro forma purchase price allocation, and any differences could be material. Such differences could affect the purchase price and allocation of the purchase price, which may affect the value assigned to the tangible or intangible assets and amount of depreciation and amortization expense recorded in the combined statements of operations. There can be no assurance that NetScout will not alter the financing structure of the Communications Business Acquisition described herein.

The unaudited pro forma combined financial information contains only adjustments that are factually supportable, directly attributable to the Transactions and with respect to the pro forma combined statements of operations, expected to have a continuing impact on the combined business. The unaudited pro forma combined financial information does not reflect any cost savings or synergies that NetScout may realize after the completion of the Communications Business Acquisition.

NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

Note 1—Basis of Presentation

On October 13, 2014, Danaher announced a definitive agreement with NetScout to combine the Communications Business with NetScout (the “Transaction” solely for purposes of this section). The Transaction will be structured as a distribution of the Communications Business to Danaher stockholders in either a spin-off transaction, a split-off transaction, or a combination split-off and spin-off, followed by a merger with a subsidiary of NetScout for consideration of 62.5 million NetScout shares, subject to adjustment. Both the distribution and merger are expected to qualify as tax-free transactions to Danaher and its stockholders, except to the extent that cash is paid to Danaher stockholders in lieu of fractional shares. If Danaher elects a spin-off, all Danaher stockholders will participate pro-rata. If Danaher elects a split-off, Danaher will conduct an exchange offer pursuant to which its stockholders will elect whether to exchange Danaher shares for common units of Newco. If the split-off exchange offer is not fully subscribed, the additional Newco common units held by Danaher will be distributed in a spin-off on a pro rata basis to Danaher stockholders. Danaher will determine which approach it will take prior to closing the transaction and no decision has been made at this time. At closing, depending on the number of shares of NetScout common stock outstanding, Danaher stockholders will receive approximately 59.5% of the shares of NetScout stock outstanding following the combination. NetScout will be the legal and accounting acquirer. The Transaction is expected to be completed in 2015.

In connection with the Merger Acquisition Agreements, it is currently expected that Newco common unit holders will receive, in aggregate, 62.5 million shares of NetScout, or a ratio of one NetScout share for each Newco common unit.

The pro forma combined financial information has been prepared for illustrative purposes only and does not purport to be indicative of the actual results that would have been achieved by NetScout if the Communications Business Acquisition had already occurred for the periods presented or that will be achieved in the future.

The accompanying unaudited pro forma combined balance sheet assumes the Communications Business Acquisition took place on September 30, 2014 and combines NetScout’s historical consolidated balance sheet as of September 30, 2014 with the Communications Business’ historical unaudited combined condensed balance sheet as of September 26, 2014 and applies pro forma adjustments to the resulting amounts.

The unaudited pro forma combined statements of operations for the fiscal year ended March 31, 2014 and the six months ended September 30, 2014 assume that the Communications Business Acquisition took place on the first day of the earliest period presented (April 1, 2013). The unaudited pro forma combined statement of operations for the year ended March 31, 2014 combines NetScout’s historical consolidated statement of operations for the fiscal year 2014 with the Communications Business’ historical combined condensed statement of operations for the fiscal year ended December 31, 2013 and applies pro forma adjustments to the resulting amounts. The unaudited pro forma combined statement of operations for the six months ended September 30, 2014 combines NetScout’s historical consolidated statement of operations for the six months ended September 30, 2014 with the Communication Business’ historical combined condensed statement of operations for the six months ended September 26, 2014 and applies pro forma adjustments to the resulting amounts.

The unaudited pro forma combined statement of operations for the year ended March 31, 2014 has been prepared utilizing period ends that differ by less than 93 days, as permitted by Regulation S-X. Omitted from the unaudited pro forma combined statement of operations for the year ended March 31, 2014 are the results of operations of the Communications Business for the three months ended March 28, 2014 (“Communications Business’ Fiscal Q1 2014”). The results of operations of the Communications Business for the three months ended March 29, 2013 (“Communications Business’ Fiscal Q1 2013”) have been included in lieu of the omitted period. The Communications Business’ Fiscal Q1 2014 reflected product revenue, service revenue, gross profit

and income from operations of $168.9 million, $54.6 million, $159.8 million, and $43.5 million, respectively. The Communications Business’ Fiscal Q1 2013 reflected product revenue, service revenue, gross profit and income from operations of $171.0 million, $48.1 million, $156.4 million, and $51.6 million, respectively.

Certain reclassifications have been included within the pro forma adjustments to conform the Communications Business’ historical financial statements to NetScout’s financial statement classifications. Upon completion of the Communications Business Acquisition, NetScout will perform a further review of the Communication Business’ accounting policies. As a result of that review, NetScout may identify additional differences between the accounting policies of the two companies that, when conformed, could have a material impact on the combined financial statements.

Note 2—Unaudited Pro Forma Adjustments

The pro forma adjustments included in the accompanying information do not reflect the final purchase price or final allocation of the excess of the purchase price over the net book value of the net assets of the Communications Business. The fair value assigned to the various tangible and intangible assets acquired, including goodwill, is preliminary and subject to change. Final adjustments may result in a materially different purchase price and allocation of the purchase price, which will affect the value assigned to the tangible or intangible assets and the depreciation and amortization expense recorded in the consolidated statements of operations.

Unaudited Pro Forma Combined Balance Sheet

Transaction Adjustments

(A) | Represents reclassifications within the Balance Sheet and Statements of Operations of the Communications Business to conform them to the classifications of the financial statements of NetScout. The reclassifications relate to breaking out financial statement captions not separately discussed by the Communications Business.

(B) | Represents the funding by Danaher of certain pension and post-retirement plans that are being assumed by NetScout such that the cash to be received from Danaher is equivalent to the projected benefit obligation as of September 30, 2014.

(C) | Represents the elimination of the book value of certain property from the historic balance sheet of the Communications Business, which will be retained by Danaher after the Transactions.

(D) | Represents a receivable related to the pre-closing liabilities of the Communications Business that are to be paid by NetScout and fully reimbursed by Danaher pursuant to the Merger Agreement.

(E) | Represents a contingent receivable of $6.8 million related to income tax matters for which NetScout has been indemnified by Danaher pursuant to the Merger Agreement. The actual amounts that NetScout may be obligated to pay and ultimately reimbursed by Danaher could vary depending upon the outcome of the unresolved tax matters, which may not be resolved for several years.

Pro Forma Adjustments

(F) | Represents the adjustment to the inventory at Communications Business, in order to record the inventory of Communications Business at its estimated fair value. The related inventory is expected to be sold within the

| next three months; therefore the adjustment has not been reflected in the accompanying pro forma combined statements of operations, as it will not have a continuing impact on the combined entity.

(G) | Represents the adjustment to the net book value of the plant, property and equipment of the Communications Business, in order to record it at its fair value as of the assumed acquisition date.

(H) | Represents the elimination of the historical goodwill of the Communications Business of $709.0 million and the addition of goodwill of $1,628.7 million related to the Communications Business Acquisition. A preliminary calculation of the goodwill based on the excess of estimated purchase price over the fair values of the assets acquired and liabilities assumed resulting from the Communications Business Acquisition is shown below (in thousands):

Purchase Price Allocation: |  |  |  |
Total equity consideration |  |  | 2,380,625 | (1)
Less: Equity consideration for replacement awards |  |  | (21,625 | )(2)
Estimated purchase price |  |  | 2,359,000 |

Deferred tax liabilities, net |  |  | (370,696 | )
Goodwill |  |  | 1,628,695 |

| (1) | Represents 62.5 million new shares of common stock of NetScout, expected to be issued to the existing common unit holders of Newco based on the November 21, 2014 NetScout common stock closing share price of $38.09 per share. The final consideration could significantly differ from the amounts presented in the unaudited pro forma financial information due to movement in the price of NetScout common stock as of the closing of the Merger.

| (2) | Represents the value of certain outstanding Danaher equity awards held by Newco employees for which continuing employees will receive value after the closing date. A portion of this amount relates to awards that have been modified such that the awards are expected to be vested in Danaher shares after the anticipated closing date of the Merger. These future compensation amounts will be settled in shares other than shares of the acquired business. The balance of this amount also represents future compensation expense and relates to a cash award to be paid by NetScout to acquired Newco employees on the later of the first anniversary of the transaction closing date or August 4, 2016. The cash payment by NetScout will be reimbursed by Danaher. These items are further described in the Separation and Distribution Agreement and have been accounted for separately from the Communications Business Acquisition.

NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION—(Continued)

The final purchase price will vary based on the trading price of NetScout common stock on the date that the Transactions close. For purposes of this unaudited pro forma combined financial information, it has been assumed to be the closing share price as of November 21, 2014. For each $1 change in the price of NetScout common stock, the estimated purchase price will increase or decrease by approximately $62.5 million. Such an increase or decrease would result in an increase or decrease to goodwill from that shown in the unaudited pro forma combined balance sheet as of September 30, 2014. The final allocation of the purchase price may have a material impact on the pro forma combined balance sheet and therefore final goodwill recorded could be materially different than the amount calculated.

The proposed transaction results in the recognition of significant intangible assets which requires management to make assumptions and estimates to determine the fair value of these assets. The following discussion sets forth the methodologies, assumptions and estimates used in the preliminary determination set forth in these pro forma financial statements:

Trademarks have been valued using the relief from royalty method for each significant portfolio of trademarks to be acquired. This method requires management to estimate the future revenues associated with trademarks, estimate a market royalty rate for the use of the trademarks, estimate an effective tax rate, and estimate a discount rate used to calculate the present value of the savings generated by purchasing the trademarks versus paying projected royalty payments to third parties.

Customer relationships have been valued using an excess earnings approach. This method requires management to estimate the future revenues associated with each existing customer base, estimate a customer attrition rate, estimate contributory asset charges, estimate operating expenses associated with obtaining new customers and developing new products, estimate an effective tax rate, and estimate a discount rate used to calculate the present value of the future expected cash inflows from the existing customer base.

Developed technology assets have been valued using the relief from royalty method. This method requires management to estimate the future revenues associated with the technologies to be acquired, estimate technology migration curves for the identified technologies, estimate a market royalty rate for the use of the technologies being acquired, estimate an effective tax rate, and estimate a discount rate used to calculate the present value of the savings generated by purchasing the technology versus paying projected royalty payments to third parties.

Other intangibles primarily relate to projected backlog. Valuing the backlog intangibles required management to estimate the revenues associated with in-process orders and the costs associated with fulfilling those orders.

Future revenues were estimated using both projections provided by the Communications Business and NetScout’s own assumptions and projections. Royalty rates were estimated by calculating an average of selected market observable royalty rates for similar trademarks and technologies. Discount rates were estimated by adjusting the implied discount rate from NetScout’s deal model for risks associated with individual assets based on the characteristics of each asset. Management estimated the tax rate at 38% which approximates a blended effective rate for the tax jurisdictions where these assets reside. Customer attrition and technology migration curves were calculated using historical information of the Communications Business about changes in the customer base and in technology source code. Finally, costs to fulfill orders were estimated based on existing financial metrics and costs associated with the intangible assets being acquired. These assumptions are considered reasonable by management and are Level Three fair value measures under US generally accepted accounting principles.

(I) | Represents the elimination of $211.4 million of the historical Communications Business’ intangible assets and the allocation of $1,053.3 million of the estimated purchase price of the Communications Business Acquisition to intangible assets comprising of the asset classes shown in Note (H) above.

85

##### Table of Contents

NETSCOUT SYSTEMS, INC.

NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION—(Continued)

(J) | Represents the adjustment necessary to recognize the fair value of the performance obligations assumed by NetScout for deferred revenue of the Communications Businesses.

(K) | Represents a net increase to deferred tax liabilities resulting from the assignment of a portion of the estimated purchase price allocation to identifiable tangible and intangible assets which are not expected to be deductible for tax purposes ($323.1 million), as well as the valuation of historical deferred tax assets of the Communications Business ($6.0 million).

(L) | Reflects the (i) elimination of the historical equity of the Communications Business (which results in a reduction to pro forma equity of $829.6 million after consideration of funding of certain liabilities by Danaher as noted in notes (B)(C)(D) and (E)); (ii) addition of equity recorded for the issuance of 62.5 million shares of NetScout common stock issued as Equity Consideration at the November 21, 2014 price of $38.09 per share (which results in an increase in pro forma equity of $2,380.6 million); and (iii) a $7.0 million (after tax) impact to retained earnings of transaction costs associated with the Communication Business Acquisition. As these transaction costs are not expected to have a continuing impact on the combined entity, they were not included in the pro forma combined statements of operations for any period presented; however, pro forma effect has been given to the incurrence of all expected transaction costs in the pro forma combined balance sheet as of September 30, 2014. The net effect of these adjustments to pro forma equity is an increase of $1,544.0 million.

Unaudited Pro Forma Combined Statements of Operations

(M) | Represents the adjustment to revenues to reflect the measurement of deferred revenue based upon the fair value of the performance obligation assumed.

(N) | Represents the elimination of non-recurring transaction costs incurred during the six month period ended September 30, 2014 of $1.4 million that are directly related to the Transactions. No transaction costs were incurred during the fiscal year ended March 31, 2014.

(O) | Represents the net adjustment necessary to reflect the elimination of depreciation of certain property that is being retained by Danaher as part of the transactions and the additional lease expense that will be incurred in relation to such buildings pursuant to the Merger Agreements. Depreciation expense recorded in the Communications Businesses for this property was $1.0 million and $0.5 million for the year ended December 31, 2013 and the six months ended September 26, respectively. Total rent expense to be recorded for the year ended March 31, 2014 and the six months ended September 30, 2014 is $2.3 million and $1.2 million, respectively.

(P) | Reflects the pro forma adjustments for the amortization expense resulting from the allocation of a portion of the estimated purchase price of the Communications Business Acquisition to intangible assets.

NetScout has estimated the pro forma amortization expense of acquired intangibles for the following periods based upon the estimated fair value and expected remaining useful lives (in thousands):

|  | Classification of Expense |  | Six Months Ended September 30, 2014 |  |  | Year Ended March 31, 2014 |

(Q) | Reflects the estimated tax effect of pro forma adjustments to income before provision for income taxes using an estimated blended statutory rate of 38.0% for the periods presented based on the impact of the Communications Business Acquisition on the combined company, as the effective rate approximates the statutory rate for the periods presented.

(R) | Reflects the pro forma total number of shares outstanding giving effect to the common stock issued as consideration for the Communications Business Acquisition and the Retention Awards. The pro forma weighted average number of shares of NetScout common stock outstanding for the fiscal year ended March 31, 2014 and the six months ended September 30, 2014 have been calculated as if the common stock issued as part of the Communications Business Acquisition and the replacement equity awards had been issued or purchased as of April 1, 2014. The following table sets forth the computation of pro forma adjustment to basic and diluted shares for the following periods (in thousands):

|  | Six Months Ended September 30, 2014 |  |  | Year Ended March 31, 2014 |
|  | Basic |  |  | Diluted |  |  | Basic |  |  | Diluted |

NetScout Dividend Policy

NetScout currently intends to retain its future earnings, if any, to finance the development and expansion of its business and is limited in its ability to pay cash dividends under the terms of its current credit facility. Therefore, NetScout does not intend to pay cash dividends on its common stock for the foreseeable future. Any future determination to pay dividends will be at the discretion of NetScout’s board of directors and will depend on NetScout’s financial condition, results of operations and capital requirements, restrictions contained in any financing instruments and such other factors as the NetScout board of directors deems relevant.

THE TRANSACTIONS

Overview

On October 12, 2014, NetScout and Danaher agreed to enter into the Transactions to effect the transfer of the Communications Business to NetScout. These Transactions provide for the separation and distribution of the Communications Business and the subsequent mergers of (a) Merger Sub with and into Newco, with Newco surviving as a wholly-owned subsidiary of NetScout and (b) Newco with and into Merger Sub II, with Merger Sub II surviving as a wholly-owned subsidiary of NetScout. In order to effect the Separation, the Distribution and the Mergers, Danaher, Newco, NetScout, Merger Sub and Merger Sub II entered into the Merger Agreement and Danaher, Newco and NetScout entered into the Distribution Agreement. In addition, Danaher, Newco, NetScout and certain of their respective affiliates have entered into, or will enter into, various ancillary agreements in connection with the Transactions. These agreements, which are described in greater detail in this document, govern the relationship among Danaher, Newco, NetScout and their respective affiliates after the Separation, the Distribution and the Mergers.

The Communications Business consists of the communications group business of Danaher conducted under the brands Tektronix Communications, Fluke Networks and Arbor Networks, and including Newco and its subsidiaries, but excluding Danaher’s data communications cable installation business and its communication service provider business. Prior to the consummation of the Distribution and the First Merger, Danaher will convey to Newco or one or more subsidiaries of Newco certain assets and liabilities constituting the Communications Business.

Immediately after the Distribution and on the closing date of the Mergers, Merger Sub will merge with and into Newco, whereby the separate corporate existence of Merger Sub will cease and Newco will continue as the surviving company and as a wholly-owned subsidiary of NetScout. In the First Merger, each Newco common unit will be converted into the right to receive NetScout common stock based on the exchange ratio set forth in the Merger Agreement, as described in the section of this document entitled “The Merger Agreement—Merger Consideration.” Afterwards, Newco will merge with and into Merger Sub II, whereby the separate corporate existence of Newco will cease and Merger Sub II will continue as the surviving company and as a wholly-owned subsidiary of NetScout. After the Mergers, NetScout will own and operate the Communications Business through Merger Sub II and will also continue its current businesses. All shares of NetScout common stock, including those issued in the First Merger, will be listed on NASDAQ under NetScout’s current trading symbol “NTCT.”

In connection with the First Merger, NetScout expects to issue approximately 62,500,000 shares of NetScout common stock to Danaher stockholders, assuming no adjustment pursuant to the Merger Agreement. Calculated based on the closing price on NASDAQ of NetScout common stock as of [—], 2015, the shares of NetScout common stock that NetScout expects to issue to Danaher stockholders as a result of the Transactions would have had a market value of approximately $[—] billion in the aggregate (the actual value will not be known until the closing date). See “—Calculation of Merger Consideration.”

Transaction Timeline

Below is a step-by-step list illustrating the material events relating to the Separation, the Distribution and the Mergers. Each of these events is discussed in more detail elsewhere in this document.

Step #1—Internal Restructuring; The Separation. Prior to the Distribution and the First Merger, Danaher will convey to Newco or one or more subsidiaries of Newco certain assets and liabilities constituting the Communications Business, including certain subsidiaries of Danaher, and will cause any applicable subsidiary of Newco to convey to Danaher or its designated subsidiary (other than Newco or any of Newco’s subsidiaries) its specified excluded assets and excluded liabilities.

Step #2—The Distribution—Exchange Offer and/or Spin-Off. On the closing date of the Mergers, Danaher will distribute 100% of the Newco common units to Danaher stockholders either through an exchange offer followed by, in the event the exchange offer is not fully subscribed, a spin-off distribution or in a spin-off distribution not including an exchange offer. Danaher expects for the Distribution to be effected through an exchange offer, but the ultimate structure selected will be based on market conditions. In the exchange offer, Danaher will offer its stockholders the option to exchange all or a portion of their shares of Danaher common stock for Newco common units. In the event the exchange offer is not fully subscribed, Danaher will distribute the remaining Newco common units owned by Danaher on a pro rata basis to Danaher stockholders whose shares of Danaher common stock remain outstanding after consummation of the exchange offer.

Step #3—The Mergers. In the First Merger, Merger Sub will be merged with and into Newco, with Newco surviving as a wholly-owned subsidiary of NetScout. Immediately thereafter, in the Second Merger, Newco will be merged with and into Merger Sub II, with Merger Sub II surviving as a wholly-owned subsidiary of NetScout. In the First Merger, each outstanding Newco common unit (except Newco common units held by Danaher, Newco, NetScout or Merger Sub) will be converted into the right to receive a number of shares of NetScout common stock equal to (x) 62.5 million shares of NetScout common stock plus the product of (A) 1.46 multiplied by (B) the number of shares of NetScout common stock issued in any acquisition after the date of the Merger Agreement and prior to the effective time of the First Merger, divided by (y) the aggregate number of Newco common units issued and outstanding as of immediately prior to the effective time of the First Merger.

Set forth below are diagrams that graphically illustrate, in simplified form, the existing corporate structure, the corporate structure immediately following the Separation and Distribution but before the First Merger, the corporate structure immediately following the consummation of the First Merger, and the corporate structure immediately following the consummation of the Second Merger.

The Separation and the Distribution

The Separation

Prior to the First Merger, pursuant to the terms of the Distribution Agreement, Danaher will convey to Newco or one or more subsidiaries of Newco certain assets and liabilities constituting the Communications Business, and will cause any applicable subsidiary of Newco to convey to Danaher or its designated subsidiary (other than Newco or any of Newco’s subsidiaries) its specified excluded assets and excluded liabilities, in order to separate and consolidate the Communications Business under Newco. Immediately thereafter, Danaher will contribute all the equity interests in each subsidiary of Newco to Newco in exchange for a number of Newco common units.

The Distribution

On the closing date of the Mergers, Danaher will distribute 100% of the Newco common units to Danaher stockholders through either an exchange offer followed by, in the event the exchange offer is not fully subscribed, a spin-off distribution or in a spin-off distribution not including an exchange offer. In the case of an exchange offer, Danaher will offer its stockholders the option to exchange all or a portion of their shares of Danaher common stock for Newco common units. In the event the exchange offer is not fully subscribed, Danaher will distribute the remaining Newco common units owned by Danaher on a pro rata basis to Danaher stockholders whose shares of Danaher common stock remain outstanding after consummation of the exchange offer. If the Distribution is structured as a spin-off not including an exchange offer, Danaher will distribute in the spin-off the Newco common units owned by Danaher on a pro rata basis to Danaher stockholders.

An agent appointed by Danaher will hold, for the account of the relevant Danaher stockholders, the global certificate(s) representing all of the outstanding Newco common units pending the consummation of the First Merger. Newco common units will not be traded during this period. Following the consummation of the Distribution and as part of the First Merger, each Newco common unit (except Newco common units held by Danaher, Newco, NetScout or Merger Sub) will be converted into the right to receive fully paid and nonassessable shares of NetScout common stock, as further described below under “—Calculation of the Merger Consideration.”

The Mergers

Under the Merger Agreement and in accordance with the DGCL and the DLLCA, at the effective time of the First Merger, Merger Sub will merge with and into Newco. As a result of the First Merger, the separate corporate existence of Merger Sub will cease and Newco will continue as the surviving company and as a wholly-owned subsidiary of NetScout and will succeed to and assume all the rights, powers and privileges and be subject to all of the obligations of Merger Sub in accordance with the DGCL and the DLLCA. In the First Merger, each Newco common unit will be converted into the right to receive NetScout common stock based on the exchange ratio set forth in the Merger Agreement, as described in the section of this document entitled “The Merger Agreement—Merger Consideration.” The certificate of formation and the limited liability company operating agreement of Newco in effect immediately prior to the First Merger will be amended and restated in their entirety following the consummation of the First Merger. Immediately following the First Merger, Newco will merge with and into Merger Sub II. As a result of the Second Merger, the separate corporate existence of Newco will cease and Merger Sub II will continue as the surviving company and as a wholly-owned subsidiary of NetScout and will succeed to and assume all the rights, powers and privileges and be subject to all of the obligations of Newco in accordance with the DLLCA.

Calculation of the Merger Consideration

The Merger Agreement provides that, at the effective time of the First Merger, each issued and outstanding Newco common unit (except Newco common units held by Danaher, Newco NetScout or Merger Sub) will be automatically converted into a number of shares of NetScout common stock equal to (x) 62.5 million shares of NetScout common stock plus the product of (A) 1.46 multiplied by (B) the number of shares of NetScout common stock issued in any acquisition by NetScout prior to the effective time of the First Merger divided by (y) the aggregate number of Newco common units issued and outstanding immediately prior to the effective time of the First Merger. In addition, Newco will authorize the issuance of a number of Newco common units such that the total number of Newco common units outstanding immediately prior to the First Merger will be that number that results in the exchange ratio in the First Merger equaling one. As a result, each Newco common unit (except Newco common units held by Danaher, Newco, NetScout or Merger Sub) will be converted into one share of NetScout common stock in the First Merger. The calculation of the merger consideration as set forth in the Merger Agreement is expected to result, prior to the elimination of fractional shares, in Newco’s members immediately prior to the merger collectively holding approximately 59.5% of the outstanding equity interests of NetScout on a fully-diluted basis immediately following the First Merger and NetScout’s stockholders immediately prior to the First Merger collectively holding approximately 40.5% of such equity interests on a fully-diluted basis.

No fractional shares of NetScout common stock will be issued pursuant to the First Merger. Any holder of Newco common units who would otherwise be entitled to receive a fraction of a share of NetScout common stock (after aggregating all fractional shares issuable to such holder) shall, in lieu of such fraction of a share, be paid in cash the dollar amount (rounded to the nearest whole cent), after deducting any required withholding taxes, on a pro rata basis, without interest, determined by multiplying such fraction by the closing price of a share of NetScout common stock on NASDAQ on the last business day prior to the closing of the First Merger.

Danaher designs, manufactures and markets professional, medical, industrial and commercial products and services, which are typically characterized by strong brand names, innovative technology and major market positions. The Communications Business is run primarily through Danaher’s Tektronix Communications, Arbor Networks and Fluke Networks Enterprise business. As part of Danaher’s strategy, Danaher’s board of directors and senior management have reviewed Danaher’s portfolio of businesses and assets to determine whether changes might be advisable and to consider possible transactions, including possible disposition and merger opportunities, in order to maximize value for Danaher stockholders.

From time to time over a number of years, Anil K. Singhal, NetScout’s Chief Executive Officer, and representatives of Danaher engaged in preliminary, informal conversations regarding potential opportunities involving the two companies. Danaher’s management had from time to time informed Danaher’s board of directors of these discussions and of the potential opportunities between the two companies.

On July 1, 2014, Mr. Singhal and James A. Lico, Danaher’s Executive Vice President, had a telephonic discussion regarding the potential combination of NetScout and the Communications Business.

On July 11, 2014, Mr. Singhal and H. Lawrence Culp, Jr., Danaher’s then President and Chief Executive Officer, and Daniel L. Comas, Danaher’s Executive Vice President and Chief Financial Officer, met in Washington, D.C. and had a preliminary discussion about the potential combination of NetScout and the Communications Business.

On July 15, 2014, immediately after a regularly scheduled meeting of NetScout’s board of directors, Mr. Singhal met with NetScout’s Finance Committee, the committee historically used by NetScout’s board of directors to evaluate strategic opportunities, and informed the Finance Committee that he had preliminary discussions with Danaher about a possible transaction involving the Communications Business. The Finance Committee requested that Mr. Singhal obtain additional details about the potential transaction and authorized NetScout to begin conducting preliminary due diligence relating to the Communications Business.

On July 15, 2014, Jean Bua, NetScout’s Chief Financial Officer, and Mr. Comas, had a telephone call in which they discussed the potential business combination and the possible structure of the transaction.

On July 18, 2014, Mr. Singhal, Ms. Bua, Mr. Culp and Mr. Comas had a telephone call in which they discussed the respective businesses, the structure of a possible transaction and the general timing of a possible transaction.

While Danaher considered alternate structures for a combination of the Communications Business with Netscout (i.e., a carve-out or merger of the business with Netscout in exchange for cash or stock), the tax-related benefits to Danaher and its stockholders of a Reverse Morris Trust structure (as described in more detail in the immediately following paragraph), together with the ability for Danaher shareholders to continue to own shares representing a majority stake in the combined business, led Danaher to limit its proposal to a Reverse Morris Trust structure.

On July 21, 2014, Mr. Singhal met with NetScout’s Finance Committee and provided additional details about the proposed transaction, including the possibility that the transactions would be structured as a Reverse Morris Trust. In general, in a Reverse Morris Trust transaction, Danaher could dispose of the Communications Business to NetScout on a tax-free basis to Danaher and its stockholders through a spin-off or split-off distribution of the Communications Business to Danaher’s stockholders immediately followed by a merger of a newco entity owning the Communications Business with a subsidiary of NetScout in exchange for equity of NetScout. The Reverse Morris Trust structure was feasible in this case because the value of the Communications Business exceeded the value of NetScout’s existing business, and attractive because a taxable disposition of the Communications Business might otherwise have made the transaction financially unattractive to Danaher or have required NetScout to pay additional consideration. In addition, in a Reverse Morris Trust structure, NetScout

95

##### Table of Contents

would primarily be able to issue equity of NetScout as consideration in the transaction, relieving NetScout from incurring significant debt to fund a cash acquisition of this magnitude. Mr. Singhal noted the preliminary structure of the transaction under consideration and informed NetScout’s Finance Committee that he expected to determine whether the transaction was feasible or financially possible after an in-person meeting between certain members of the NetScout management team and the management team for Danaher and the Communications Business to be held before the end of the month of July.

Between July 25 and July 29, 2014, representatives of NetScout, NetScout’s outside counsel, Cooley LLP (“Cooley”), and Danaher had several telephone calls regarding a proposed confidentiality and non-disclosure agreement between the parties.

On July 29, 2014, NetScout and Danaher executed the confidentiality agreement.

On July 31 and August 1, 2014, members of each of the management teams of Danaher, including Messrs. Lico, Culp and Comas, and NetScout, including Mr. Singhal, Ms. Bua and Mr. Levinson, held in person meetings, at Danaher’s headquarters in Washington, D.C. At these meetings, representatives of Danaher reviewed the Communications Business, including its products, views on the industry, infrastructure and operations, potential synergies and a location-by-location overview, together with preliminary financial information. Representatives of NetScout also reviewed NetScout’s business, products and views on the industry. In addition, representatives of Danaher referenced an illustrative valuation of the Communications Business of $3.0 billion for discussion purposes, based on an assumed value of $44 per share of NetScout common stock. Representatives of NetScout did not comment on the illustrative price at such time and noted that they would revert with a response following further consideration.

On August 12, 2014, NetScout’s board of directors met to discuss NetScout’s progress on the proposed transaction with senior management, Cooley and NetScout’s financial advisor, RBC Capital Markets. Mr. Singhal discussed the strategic rationale for the proposed transaction. During the meeting, NetScout’s board of directors discussed financial aspects of the proposed transaction with RBC Capital Markets. Following the discussion, NetScout’s board of directors authorized management to prepare a non-binding letter of intent and continue discussions with Danaher. On August 15, 2014, NetScout furnished Danaher with a non-binding letter of intent for a possible acquisition by NetScout of the Communications Business through a Reverse Morris Trust structure, which would include the acquisition of the Communications Business through a reverse triangular merger immediately following a spin-off distribution of the Communications Business to Danaher’s stockholders, with consideration in the form of shares of NetScout common stock. The non-binding letter of intent contemplated, among other things, a proposed valuation for the Communications Business of $2.4 billion to $2.6 billion, based on NetScout’s then closing stock price of approximately $44 per share.

Between August 15, 2014 and August 22, 2014, Messrs. Singhal, Culp and Comas discussed various terms of the non-binding letter of intent, including the proposed consideration for the Communications Business. On August 20, 2014, Mr. Culp indicated to Mr. Singhal that Danaher would be willing to accept a valuation of $2.8 billion for the Communications Business, based on an assumed value of $44 per share of NetScout common stock. On August 21, Mr. Singhal indicated to Mr. Culp that NetScout proposed a valuation of $2.7 billion for the Communications Business, based on an assumed value of $44 per share of NetScout common stock. Later on August 21, Mr. Comas indicated to Mr. Singhal that Danaher’s proposal remained at a valuation of $2.8 billion for the Communications Business, based on an assumed value of $44 per share of NetScout common stock. During such period, Mr. Singhal also conferred with John R. Egan, NetScout’s lead independent director, and RBC Capital Markets regarding financial matters pertaining to the Communications Business.

On August 22, 2014, Mr. Comas indicated that Danaher proposed a valuation of $2.75 billion for the Communications Business, equaling approximately 62.5 million shares of NetScout common stock at an assumed value of $44 per share of NetScout common stock, which proposal Mr. Singhal indicated he would find acceptable subject to review with the NetScout board of directors. Later on August 22, 2014, NetScout’s board of

During the meeting, Mr. Singhal updated NetScout’s board of directors on the recent discussions with Danaher regarding the proposed merger consideration, exclusivity periods and other matters. Later in the day, Danaher sent a revised non–binding letter of intent to NetScout, which contemplated an aggregate purchase price of $2.75 billion based on the issuance of 62.5 million shares of NetScout common stock at an assumed value of $44 per share, reflecting the proposal communicated by Mr. Comas to Mr. Singhal earlier that day and subsequently discussed with the NetScout board of directors.

On August 23 and August 24, 2014, Mr. Singhal had additional discussion with Danaher representatives regarding the non-binding letter of intent.

On August 24, 2014, Danaher’s board of directors received an update regarding the status of the potential transaction with NetScout.

On August 25, 2014, NetScout’s board of directors held a meeting, with representatives of NetScout’s senior management and legal and financial advisors attending, to discuss and obtain approval to enter into the proposed non-binding letter of intent. During the meeting, RBC Capital Markets discussed the financial terms and certain related aspects of the proposed letter of intent and Cooley discussed fiduciary duty and other legal considerations relating to the proposed transaction and structure. Following the discussion, the NetScout board of directors authorized the non-binding letter of intent. Later in the day, NetScout executed the non-binding letter of intent with Danaher.

On August 26, 2014, NetScout and its legal and financial representatives had a call with Danaher and its legal representatives to discuss the then-current structure of the Communications Business.

remaining issues that were resolved during that period included the precise manner for calculation of the exchange ratio, the circumstances under which a termination fee would be payable by NetScout, the size of the termination fee, closing conditions relating to the proposed IRS tax letter ruling, NetScout’s termination rights associated with tax matters, structural matters relating to the separation being structured as a spin-off or split-off, certain indemnification matters and the remedy for potential differences between the unaudited financial statements of the Communications Business provided prior to the signing of definitive agreements and the audited financial statements of the Communications Business to be completed after execution of the definitive agreements (each as described in more detail in the section of this document entitled “The Merger Agreement”). Final issues resolved during such time period included the negotiation of certain employee benefit matters and certain tax matters. Additionally, the parties completed their due diligence.

Following continued negotiations on October 11, 2014 and October 12, 2014, the parties finalized their negotiation of all the material terms of the definitive documents for the Transactions, and agreed to submit the Transactions for review and approval by their respective boards of directors.

On October 12, 2014, NetScout’s board of directors met, together with representatives of NetScout’s senior management and legal and financial advisors, to review the final structure and terms of the Transactions. NetScout’s legal advisors reviewed the principal terms of the Merger Agreement, the Distribution Agreement, the Employee Matters Agreement, the Tax Matters Agreement and other related agreements. Also at this meeting, RBC Capital Markets reviewed with NetScout’s board of directors its financial analysis of the merger consideration to be paid by NetScout in the First Merger and delivered to NetScout’s board of directors an oral opinion, confirmed by delivery of a written opinion dated October 12, 2014, to the effect that, as of that date and based on and subject to the matters described in the opinion, the merger consideration to be paid by NetScout in the First Merger was fair, from a financial point of view, to NetScout. Following further discussion, NetScout’s board of directors, by unanimous vote, determined that the Merger Agreement and the proposed transactions with Danaher were advisable and fair to, and in the best interests of, NetScout and its stockholders, approved the Merger Agreement and unanimously recommended that NetScout stockholders approve the issuance of shares of NetScout common stock pursuant to the Merger and approve any other transactions contemplated by the Merger Agreement, including the Merger.

Also on October 12, 2014, the board of directors of Danaher met, together with representatives of management, to review the final structure and terms of the Transactions. Danaher’s management provided information on the due diligence that Danaher conducted with respect to NetScout as well as the terms, structure and strategic rationale of the proposed transactions and the anticipated financial and business impact thereof with respect to Danaher. Following discussion, the board of directors of Danaher, by unanimous vote of all members present, determined that the Merger Agreement and the transactions were advisable and in the best interests of Danaher and its stockholders and approved the Merger Agreement, the Distribution Agreement, the Voting Agreement and the forms of the other transaction agreements and the transactions contemplated thereby.

Following their respective board meetings, NetScout, Danaher and Newco, as the case may be, then signed the Merger Agreement and the Distribution Agreement and Mr. Singhal and Danaher signed the Voting Agreement.

On October 13, 2014, before the opening of trading on NASDAQ and the NYSE, NetScout and Danaher issued press releases announcing the Transactions.

NetScout’s Reasons for the Transactions

In reaching its decision to approve the Merger Agreement and recommend that NetScout stockholders approve the issuance of shares of NetScout common stock in the First Merger, the board of directors of NetScout considered, among other things, the strategic and financial benefits that could be expected to be achieved by combining NetScout and the Communications Business relative to the future prospects of NetScout on a

##### Table of Contents

standalone basis, the relative actual results of operations and prospects of NetScout and of the Communications Business, as well as other strategic alternatives that may be available to NetScout, and the risks and uncertainties associated with the Transactions and with such alternatives.

In that process, the board of directors of NetScout considered the following factors as generally supporting its decision to approve the Merger Agreement and recommend that NetScout stockholders approve the issuance of shares of NetScout common stock in the First Merger:

Advances Strategic Objectives. The acquisition advances NetScout’s strategic objectives of expanding its product portfolio across service assurance and performance analytics, business intelligence and cyber security solutions for communications service providers and large and small enterprises, and government organizations. Consequently, NetScout believes that the acquisition will enhance its ability to create long-term value for its stockholders, including by providing the following benefits:

| • |  | Enhanced Financial Performance. The acquisition enables NetScout to grow from a revenue base of $397 million in fiscal year 2014 and a projected revenue base of $450 million to $465 million in fiscal year 2015 to a combined non-GAAP annual revenue base of more than $1.2 billion, with an expanded range of complementary products, which is expected to position NetScout to drive strong revenue growth and improved profitability over the long term. Over the long term, NetScout management believes that the combined company will be capable of growing revenue at an approximate compounded annual growth rate of 10 percent.

| • |  | Expanded Addressable Markets and Broader Customer Base. The acquisition increases NetScout’s addressable market and broadens both its service provider and enterprise customer base and accelerates its entry into the cyber security and business intelligence markets. The acquisition significantly expands NetScout’s total addressable market to more than $8 billion. International Data Corporation (IDC) estimated that spending on network and application performance management solutions, NetScout’s core market prior to the acquisition, was approximately $5.0 billion in 2013. However, NetScout did not have the requisite offerings to fully address key segments within its core market. The acquisition provides NetScout with new capabilities to fill gaps in its product portfolio and target parts of these markets that were previously not available to NetScout such as radio access network optimization and the low-mid tier of the enterprise network performance management market. Additionally, the acquisition enables NetScout to enter the cyber security and advanced analytics (business intelligence) markets in which global spending was estimated by IDC to be over $3 billion in 2013.

| • |  | Expansion of Service Provider Base. The acquisition of the Tektronix Communications business, a leading provider of service provider network monitoring solutions, provides NetScout with broader access to the service provider market, extends its reach into the RAN portion of the network, offers complementary business intelligence analytics and gives NetScout greater ability to cross-sell solutions into NetScout’s and Tektronix Communications’ existing customer bases. Having a broader, more robust technology and operational platform enables NetScout to further differentiate the company against competitors in the market.

| • |  | Expansion of NetScout’s Enterprise Customer Base. The acquisition of portions of the Fluke Networks Enterprise business, a leading provider of network monitoring solutions, allows NetScout to expand into the mid-tier and smaller enterprise market and expand NetScout’s enterprise product offerings in specialized areas such as software-as-a-service (SaaS) and cloud-based applications and WiFi monitoring.

| • |  | Extension into Adjacent Growth-Oriented Markets. The acquisition of Arbor Networks, a leading provider of network cyber attack detection and mitigation solutions for service provider and enterprise networks, allows NetScout to immediately enter the cyber intelligence and cyber security market. Arbor Networks’ offerings for distributed denial of service and advanced persistent protection are used by more than 300 service provider customers and a growing base of enterprise customers.

| • |  | Substantially Broader Portfolio of Best-in-Class Products. NetScout will gain complementary, award-winning technologies, capabilities and offerings that can better position it to deliver high-value products and services for its existing and prospective enterprise and service provider customers and better position NetScout to compete for a broader range of strategic IT management opportunities in both the enterprise and service provider markets.

| • |  | Broader and More Diverse Geographic Footprint. NetScout will expand its geographical footprint outside of North America, through the Communications Business’ existing customer accounts and through an extensive direct sales, support and service infrastructure, including value-added reseller relationships in key markets such as Southeast Asia, Australia, Japan, Europe and Latin America.

| • |  | Strong Research and Development Capabilities. The combined company is expected to have more than 35% of the workforce composed of research and development personnel, and NetScout will be better positioned to address future technology trends, accelerate innovation, and improve its overall competitive position.

Cost Synergies. NetScout expects to achieve initial annualized run-rate cost synergies of approximately five percent of the combined cost base, or approximately $45 to $55 million within two years from the consummation of the Transactions as a result of increased size, economies of scale, and elimination of redundancies after the Transactions. NetScout expects to generate additional cost synergies in subsequent years by using common infrastructure platforms, and by eliminating or reducing expenses associated with programs and capabilities already in place as NetScout aligns its go-to-market and related support programs and initiatives. However, the magnitude and timing of such synergies has yet to be determined. For a further description of expected cost synergies see “Certain Financial Forecasts Prepared by NetScout-Cost” beginning on Page 111.

Accretive Transaction. NetScout expects the Transactions to be accretive on a non-GAAP basis in the first full year of operations. NetScout expects that it will be able to leverage its purchasing power and expand its proven manufacturing techniques in ways that will improve product gross margins by a few percentage points over the next few years.

Transaction Terms and Other Considerations. The board of directors of NetScout also considered the following facts about the Transactions and combined company:

| • |  | the fact that the number of shares of common stock to be issued by NetScout is fixed and will not fluctuate based upon changes in the stock price of NetScout or Danaher prior to the completion of the First Merger.

| • |  | the fact that the Merger Agreement and the aggregate consideration to be paid by NetScout pursuant to the Merger Agreement were the result of extensive arms’-length negotiations between representatives of NetScout and of Danaher.

| • |  | the fact that the aggregate consideration to be paid by NetScout is payable in NetScout common stock, enabling NetScout to increase its revenue over 2.5 times without depleting its cash resources and incurring debt, thereby preserving its future ability to use leverage to further the growth of its business.

| • |  | the opinion, dated October 12, 2014, of RBC Capital Markets to NetScout’s board of directors as to the fairness, from a financial point of view and as of such date, to NetScout of the merger consideration to be paid by NetScout in the First Merger, which opinion was based on and subject to the procedures followed, assumptions made, factors considered and limitations and qualifications on the review undertaken as more fully described under “Opinion of NetScout’s Financial Advisor.”

| • |  | the fact that the board of directors of the combined company would be composed of all of the current directors of NetScout and one director from Danaher, expected to be James A. Lico, an Executive Vice President of Danaher.

| • |  | the fact that the executive officers of the combined company would be composed of all of the current executive officers of NetScout, but with additional management talent to be gained from the acquired companies.

##### Table of Contents

| • |  | the ability of the board of directors of NetScout under the Merger Agreement, subject to the payment of a termination fee, to withdraw or modify its recommendation to the NetScout stockholders to approve the issuance of the NetScout common stock in the First Merger in certain circumstances.

The board of directors of NetScout considered the following risk factors but determined that the benefits of the proposed transaction substantially outweighed such risks:

| • |  | the possibility that the increased revenues, earnings and efficiencies expected to result from the Transactions would fail to materialize;

| • |  | the challenges inherent in fully and successfully separating the operations of the Communications Business from Danaher and integrating Newco into NetScout, given the size of the Communications Business relative to NetScout and its operations;

| • |  | the dilution of the ownership interests of NetScout’s current stockholders that would result from the issuance of NetScout common stock in the First Merger;

| • |  | the potential payment of termination fees that NetScout would be required to make in certain circumstances under the Merger Agreement;

| • |  | the restrictions imposed on NetScout’s ability to take certain corporate actions under the terms of the Tax Matters Agreement to be entered into by NetScout and Danaher, which could reduce its ability to engage in certain future business transactions that might be advantageous;

| • |  | the risks inherent in requesting that the U.S. Federal Trade Commission and the U.S. Department of Justice allow the waiting period under the HSR Act to expire;

| • |  | the requirement in the Merger Agreement that NetScout call and hold a vote of its stockholders to approve the issuance of the NetScout common stock in the First Merger even in circumstances where the board of directors of NetScout has withdrawn or adversely changed its recommendation to the NetScout stockholders;

| • |  | the possibility that the Transactions may not be consummated and the potential adverse consequences, including substantial costs that would be incurred and potential damage to NetScout’s reputation, if the Transactions are not completed; and

| • |  | the other risks described above under the section entitled “Risk Factors” beginning on page 29.

The foregoing discussion of the information and factors considered by the board of directors of NetScout is not exhaustive, but includes the material factors considered by the board of directors of NetScout, including factors that support the Transactions as well as those that weigh against them. In view of the wide variety of factors considered by the board of directors of NetScout in connection with its evaluation of the Transactions and the complexity of these matters, the board of directors of NetScout did not consider it practical to, nor did it attempt to, quantify, rank or otherwise assign relative weights to the specific factors that it considered in reaching its decision. Rather, the board of directors of NetScout based its recommendation on the totality of the information presented to and considered by it. The board of directors of NetScout evaluated the factors described above with the assistance of NetScout’s senior management and legal and financial advisors. In considering the factors described above, individual members of the board of directors of NetScout may have given different weights to other or different factors.

This explanation of the factors considered by the board of directors of NetScout is in part forward-looking in nature and, therefore, should be read in light of the factors discussed in the sections of this document entitled “Cautionary Statement Concerning Forward-Looking Statements” and “Risk Factors.”

After careful consideration, the board of directors of NetScout resolved that the Transactions contemplated by the Merger Agreement are advisable and fair to, and in the best interests of NetScout and its stockholders and unanimously approved the Merger Agreement, the Mergers and the other Transactions.

##### Table of Contents

The board of directors of NetScout recommends that the stockholders of NetScout vote “FOR” approval of the issuance of shares of NetScout common stock in the First Merger and, if necessary or appropriate, “FOR” the adjournment or postponement of the special meeting to solicit additional proxies if there are not sufficient votes at the time of the special meeting to approve the issuance of shares of NetScout common stock in the Merger.

Opinion of NetScout’s Financial Advisor

NetScout has retained RBC Capital Markets to act as NetScout’s financial advisor in connection with the Mergers. As part of this engagement, NetScout’s board of directors requested that RBC Capital Markets evaluate the fairness, from a financial point of view, to NetScout of the merger consideration to be paid by NetScout in the First Merger. At an October 12, 2014 meeting of NetScout’s board of directors held to evaluate the Mergers, RBC Capital Markets rendered to NetScout’s board of directors an oral opinion, confirmed by delivery of a written opinion dated October 12, 2014 to the effect that, as of that date and based on and subject to the matters described in the opinion, the merger consideration to be paid by NetScout in the First Merger was fair, from a financial point of view, to NetScout. For purposes of RBC Capital Markets’ analyses and opinion, the term “merger consideration” refers to the 62.5 million shares of NetScout common stock, in the aggregate, issuable in the First Merger. The full text of RBC Capital Markets’ written opinion, dated October 12, 2014, is attached as Annex C to this proxy statement and is incorporated in this document by reference. The written opinion sets forth, among other things, the procedures followed, assumptions made, factors considered and qualifications and limitations on the review undertaken by RBC Capital Markets in connection with its opinion. The following summary of RBC Capital Markets opinion is qualified in its entirety by reference to the full text of the opinion. RBC Capital Markets delivered its opinion to NetScout’s board of directors for the benefit, information and assistance of NetScout’s board of directors (in its capacity as such) in connection with and for purposes of its evaluation of the Mergers. RBC Capital Markets’ opinion addressed only the merger consideration from a financial point of view to NetScout and did not address any other aspect of the Mergers or any related transactions. RBC Capital Markets’ opinion also did not address the underlying business decision of NetScout to engage in the Mergers or any related transactions or the relative merits of the Mergers or any related transactions compared to any alternative business strategy or transaction that might be available to NetScout or in which NetScout might engage. RBC Capital Markets does not express any opinion and does not make any recommendation to any stockholder as to how such stockholder should vote or act with respect to any proposal to be voted upon in connection with the Mergers or any related transactions.

In connection with its opinion, RBC Capital Markets, among other things:

| • |  | reviewed the financial terms of drafts, each dated October 12, 2014, of the Merger Agreement and Distribution Agreement;

| • |  | reviewed certain publicly available financial and other information, and certain historical operating data, with respect to NetScout made available to RBC Capital Markets from published sources and internal records of NetScout;

| • |  | reviewed certain publicly available financial and other information, and certain historical operating data, with respect to the Communications Business made available to RBC Capital Markets from published sources and internal records of Danaher;

| • |  | reviewed publicly available financial projections and other estimates and data relating to NetScout for the fiscal years ended March 31, 2015 and March 31, 2016 as extrapolated thereafter by the management of NetScout and financial projections and other estimates and data relating to the Communications Business prepared by the management of Danaher for the fiscal year ended December 31, 2014 as adjusted and extrapolated thereafter by the management of NetScout, in each case which RBC Capital Markets was directed to utilize for purposes of its analyses;

| • |  | conducted discussions with members of the senior managements of NetScout and Danaher with respect to the respective business prospects and financial outlook of NetScout and the Communications

##### Table of Contents

| Business and also held discussions with the senior management of NetScout regarding the strategic rationale and potential cost savings and other benefits expected by such management to be realized in the Mergers and related transactions, which we collectively refer to as “cost savings”;

| • |  | reviewed the reported prices and trading activity for NetScout common stock;

| • |  | compared certain financial metrics of NetScout and the Communications Business with those of selected publicly traded companies;

| • |  | reviewed the potential pro forma financial impact of the Mergers on the future financial performance of NetScout after taking into account potential cost savings; and

| • |  | considered other information and performed other studies and analyses as RBC Capital Markets deemed appropriate. RBC Capital Markets noted for the NetScout board of directors that it did not compare the financial terms of the Mergers to financial terms of other transactions given, in RBC Capital Markets’ view, the limited comparability of such other transactions to the Mergers.

In arriving at its opinion, RBC Capital Markets employed several analytical methodologies and no one method of analysis should be regarded as critical to the overall conclusion reached by RBC Capital Markets. Each analytical technique has inherent strengths and weaknesses, and the nature of the available information may further affect the value of particular techniques. The overall conclusion reached by RBC Capital Markets was based on all analyses and factors presented, taken as a whole, and also on application of RBC Capital Markets’ experience and judgment. Such conclusion may have involved significant elements of subjective judgment and qualitative analysis. RBC Capital Markets therefore gave no opinion as to the value or merit standing alone of any one or more portions of such analyses or factors.

In rendering its opinion, RBC Capital Markets assumed and relied upon the accuracy and completeness of all information that was reviewed by RBC Capital Markets, including all of the financial, legal, tax, accounting, operating and other information provided to or discussed with RBC Capital Markets by or on behalf of NetScout or Danaher (including, without limitation, financial statements and related notes), and upon the assurances of the managements of NetScout and Danaher that they were not aware of any relevant information that was omitted or that remained undisclosed to RBC Capital Markets. RBC Capital Markets did not assume responsibility for independently verifying and it did not independently verify such information. RBC Capital Markets assumed that the publicly available financial projections and other estimates and data relating to NetScout (as extrapolated by the management of NetScout) and the financial projections and other estimates and data relating to the Communications Business (as adjusted and extrapolated by the management of NetScout) which RBC Capital Markets was directed to utilize in its analyses were reasonably prepared on bases reflecting the best currently available estimates and good faith judgments as to the future financial performance of NetScout and the Communications Business and the other matters covered thereby and that the financial results reflected therein would be realized in the amounts and at the times projected. RBC Capital Markets also was advised that there were no audited financial statements relating to the Communications Business and RBC Capital Markets assumed that such audited financial statements, when delivered to NetScout in connection with the Mergers, would not reflect any information that would be meaningful to its analyses or opinion. RBC Capital Markets expressed no opinion as to any such financial projections and other estimates and data or the assumptions upon which they were based. RBC Capital Markets relied upon the assessments of the managements of NetScout and Danaher as to (i) the Transactions (other than the Mergers), including with respect to the timing thereof and assets, liabilities and financial and other terms involved, (ii) the potential impact on NetScout and the Communications Business of market and other trends and prospects for the technology industry, (iii) the products, technology and intellectual property of NetScout and the Communications Business, including the validity of, and risks associated with, such products, technology and intellectual property, (iv) the existing and future relationships, agreements and arrangements with, and NetScout’s ability to retain, key employees and customers of NetScout and the Communications Business, and (v) NetScout’s ability to integrate the Communications Business with the businesses and operations of NetScout. RBC Capital Markets assumed that there would be no developments with respect to any of the foregoing that would have an adverse effect on

104

##### Table of Contents

NetScout, the Communications Business, Newco, the Mergers or related transactions or that would otherwise be meaningful in any respect to its analyses or opinion. RBC Capital Markets also relied on estimates of the management of NetScout as to the capitalization of NetScout and Newco, including as to the number of fully diluted shares of NetScout common stock and Newco common units, as of the effective time of the First Merger, and RBC Capital Markets assumed that such number of shares or units, as the case may be, would not vary in any respect that would be meaningful to its analyses or opinion.

In rendering its opinion, RBC Capital Markets did not assume any responsibility to perform, and it did not perform, an independent evaluation or appraisal of any of the assets or liabilities (contingent or otherwise) of NetScout, the Communications Business or any other entity (including Newco) or business, and RBC Capital Markets was not furnished with any such valuations or appraisals. RBC Capital Markets did not assume any obligation to conduct, and it did not conduct, any physical inspection of the property or facilities of NetScout, the Communications Business or any other entity or business. RBC Capital Markets assumed that the Mergers and related transactions would be consummated in accordance with the terms of the Merger Agreement and Distribution Agreement and all applicable laws and other requirements, without waiver, modification or amendment of any material term, condition or agreement and that, in the course of obtaining the necessary regulatory or third party approvals, consents and releases for the Mergers and related transactions, no delay, limitation, restriction or condition would be imposed, including any divestiture or other requirements, that would have an adverse effect on NetScout, the Communications Business, Newco, the Mergers or related transactions (including the contemplated benefits thereof). RBC Capital Markets also assumed that the Mergers and related transactions would have the tax treatment as set forth in the Merger Agreement and the Distribution Agreement, including that the First Merger and the Second Merger would be treated as a single integrated transaction and would together qualify as a tax-free reorganization within the meaning of Section 368 of the Internal Revenue Code of 1986, as amended. RBC Capital Markets further assumed that Newco would retain or acquire all assets, properties and rights necessary for the operations of the Communications Business, that appropriate reserves, indemnification arrangements or other provisions had been made with respect to the liabilities of or relating to the Communications Business and that NetScout would not directly or indirectly assume or incur any liabilities that were contemplated to be excluded as a result of the Mergers, the related transactions or otherwise. In addition, RBC Capital Markets assumed that the final executed Merger Agreement and Distribution Agreement would not differ, in any respect meaningful to its analyses or opinion, from the drafts of the Merger Agreement and Distribution Agreement reviewed by RBC Capital Markets.

RBC Capital Markets’ opinion spoke only as of the date of its opinion, was based on conditions as they existed and information which RBC Capital Markets was supplied as of the date of its opinion, and was without regard to any market, economic, financial, legal or other circumstances or events of any kind or nature which may exist or occur after such date. RBC Capital Markets did not undertake to reaffirm or revise its opinion or otherwise comment upon events occurring after the date of its opinion and did not have an obligation to update, revise or reaffirm its opinion. RBC Capital Markets’ opinion related to the relative values of NetScout and the Communications Business. RBC Capital Markets did not express any opinion as to what the value of NetScout common stock actually would be when issued in connection with the Mergers or the prices or range of prices at which NetScout common stock may trade or otherwise be transferable at any time, whether prior to or following the Mergers and related transactions.

RBC Capital Markets’ opinion addressed only the fairness, from a financial point of view and as of the date of its opinion, of the merger consideration (to the extent expressly specified in its opinion) to NetScout. RBC Capital Markets’ opinion did not in any way address any other terms, conditions, implications or other aspects of the Mergers, the related transactions, the Merger Agreement, the Distribution Agreement or any related agreements, or any adjustment payment or other agreement, arrangement or understanding to be entered into in connection with or contemplated by the Mergers, the related transactions or otherwise. RBC Capital Markets did not evaluate the solvency or fair value of NetScout, Danaher, the Communications Business or any other entity (including Newco) or business under any state, federal or other laws relating to bankruptcy, insolvency or similar matters. RBC Capital Markets did not express any opinion as to any legal, regulatory, tax or accounting matters, as to which RBC Capital Markets understood that NetScout obtained such advice as it deemed necessary from

105

##### Table of Contents

qualified professionals. Further, in rendering its opinion, RBC Capital Markets did not express any view on, and its opinion did not address, the fairness of the amount or nature of the compensation (if any) to any officers, directors or employees of any party, or class of such persons, relative to the merger consideration or otherwise.

The issuance of RBC Capital Markets’ opinion was approved by RBC Capital Markets’ fairness opinion committee. Except as described in this summary, NetScout imposed no other instructions or limitations on the investigations made or procedures followed by RBC Capital Markets in rendering its opinion.

In preparing its opinion to NetScout’s board of directors, RBC Capital Markets performed various financial and comparative analyses, including those described below. The summary below of RBC Capital Markets’ material financial analyses provided to NetScout’s board of directors in connection with RBC Capital Markets’ opinion is not a comprehensive description of all analyses undertaken or factors considered by RBC Capital Markets in connection with its opinion. The preparation of a financial opinion is a complex analytical process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and, therefore, a financial opinion is not readily susceptible to partial analysis or summary description.

In performing its analyses, RBC Capital Markets considered industry performance, general business and economic conditions and other matters, many of which are beyond the control of NetScout and Danaher. The estimates of the future performance of NetScout and the Communications Business in or underlying RBC Capital Markets’ analyses are not necessarily indicative of actual values or actual future results, which may be significantly more or less favorable than those estimates or those suggested by RBC Capital Markets’ analyses. The analyses do not purport to be appraisals or to reflect the prices at which a company might actually be sold or acquired or the prices at which any securities have traded or may trade at any time in the future. Accordingly, the estimates used in, and the ranges of valuations resulting from, any particular analysis described below are inherently subject to substantial uncertainty and should not be taken as RBC Capital Markets’ view of the actual value of NetScout or the Communications Business.

The merger consideration to be paid by NetScout in the First Merger was determined through negotiations between NetScout and Danaher and was approved by NetScout’s board of directors. The decision to enter into the Merger Agreement and Distribution Agreement was solely that of NetScout’s board of directors. RBC Capital Markets’ opinion and analyses were only one of many factors considered by NetScout’s board of directors in its evaluation of the Mergers and should not be viewed as determinative of the views of NetScout’s board of directors, management or any other party with respect to the Mergers or related transactions or the consideration payable in the Mergers or related transactions.

The following is a brief summary of the material financial analyses provided by RBC Capital Markets to NetScout’s board of directors in connection with RBC Capital Markets’ opinion, dated October 12, 2014. The financial analyses summarized below include information presented in tabular format. In order to fully understand the financial analyses performed by RBC Capital Markets, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. Selecting portions of RBC Capital Markets’ financial analyses or factors considered or focusing on the data set forth in the tables below without considering all analyses or factors or the full narrative description of such analyses or factors, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of RBC Capital Markets’ financial analyses.

Introduction. In its analysis of the merger consideration from a financial point of view to NetScout, RBC Capital Markets performed various financial analyses, as more fully described below. Utilizing selected public companies and discounted cash flow analyses, RBC Capital Markets calculated implied enterprise value reference ranges for the Communications Business and implied per share equity value reference ranges for NetScout. RBC Capital Markets then calculated implied reference ranges of the aggregate number of shares of NetScout common stock issuable in the First Merger, referred to as “implied issuable shares,” based on the

106

##### Table of Contents

implied enterprise value and per share equity value reference ranges derived from these analyses, by (i) in the case of the low-end of such implied reference ranges, dividing the low-end of the implied enterprise value reference ranges for the Communications Business by the high-end of the implied per share equity value reference ranges for NetScout and (ii) in the case of the high-end of such implied reference ranges, dividing the high-end of the implied enterprise value reference ranges for the Communications Business by the low-end of the implied per share equity value reference ranges for NetScout. RBC Capital Markets also performed a pro forma contribution analysis to derive a range of implied issuable shares based on the relative contributions of NetScout and the Communications Business to various financial metrics of the pro forma combined company.

Financial data utilized for NetScout in the financial analyses described below was based on publicly available financial projections and other estimates and data relating to NetScout on a non-GAAP basis for the fiscal years ended March 31, 2015 and March 31, 2016 as extrapolated thereafter by the management of NetScout, which we refer to as the “NetScout forecasts,” and financial data utilized for the Communications Business in such financial analyses was based on financial projections and other estimates and data relating to the Communications Business prepared by the management of Danaher on a non-GAAP basis for the fiscal year ended December 31, 2014 as adjusted and extrapolated thereafter by the management of NetScout, which we refer to as the “Communications Business forecasts.” At the direction of the management of NetScout, RBC Capital Markets assumed, for purposes of its analyses and opinion, that no shares of NetScout common stock would be issued in connection with any acquisition effected as permitted by the terms of the Merger Agreement and, accordingly, RBC Capital Markets evaluated the aggregate number of shares of NetScout common stock issuable in the First Merger on the basis of 62.5 million shares.

Selected Public Companies Analyses. RBC Capital Markets performed selected public companies analyses of NetScout and the Communications Business in which RBC Capital Markets reviewed certain financial and stock market information of NetScout, certain financial information of the Communications Business and certain financial and stock market information of selected companies that RBC Capital Markets considered, in its professional judgment, generally relevant for comparative purposes. Financial data of the selected companies were based on publicly available research analysts’ estimates, public filings and other publicly available information. Financial data of NetScout was based on public filings and the NetScout forecasts (with such data calendarized as necessary) and financial data of the Communications Business was based on public filings and the Communications Business forecasts.

In its selected public companies analysis of NetScout, RBC Capital Markets reviewed, among other things, enterprise values, calculated as equity values based on closing stock prices on October 10, 2014 plus debt and less cash and cash equivalents and short-term and long-term investments, as a multiple of calendar year 2014 and calendar year 2015 estimated unlevered net income and also reviewed equity values, based on closing stock prices on October 10, 2014, as a multiple of calendar year 2014 and calendar year 2015 estimated earnings per share, which we refer to as “EPS,” of NetScout and the following seven selected companies in the network monitoring and management industry, which we refer to as the “selected network monitoring companies,” and the following two selected companies in the systems management industry, which we refer to as the “selected systems management companies” (we collectively refer to the selected network monitoring companies and the selected systems management companies as the “selected companies”):

The overall low to high calendar year 2014 and calendar year 2015 estimated unlevered net income multiples observed for the selected companies were 15.5x to 34.9x (with a median of 19.7x for the selected network monitoring companies and a median of 20.7x for the selected systems management companies) in the case of calendar year 2014 and 10.7x to 18.8x (with a median of 12.7x for the selected network monitoring companies and a median of 17.9x for the selected systems management companies) in the case of calendar year 2015. The overall low to high calendar year 2014 and calendar year 2015 estimated EPS multiples observed for the selected companies were 15.7x to 33.4x (with a median of 22.3x for the selected network monitoring companies and a median of 22.1x for the selected systems management companies) in the case of calendar year 2014 and 14.0x to 20.5x (with a median of 15.5x for the selected network monitoring companies and a median of 19.1x for the selected systems management companies) in the case of calendar year 2015. RBC Capital Markets noted that, based on NetScout’s closing stock price on October 10, 2014, calendar year 2014 and calendar year 2015 estimated unlevered net income multiples observed for NetScout were 21.2x and 18.2x, respectively, and calendar year 2014 and calendar year 2015 estimated EPS multiples observed for NetScout were 24.4x and 20.9x, respectively. In deriving implied per share equity value reference ranges for NetScout, RBC Capital Markets then applied the overall low to high calendar year 2014 and calendar year 2015 estimated unlevered net income multiples and calendar year 2014 and calendar year 2015 estimated EPS multiples observed for the selected companies to corresponding data of NetScout. This analysis indicated approximate implied per share equity value reference ranges for NetScout based on calendar year 2014 and calendar year 2015 estimated unlevered net income multiples of $32.07 to $65.35 and $26.92 to $43.15, respectively, and based on calendar year 2014 and calendar year 2015 estimated EPS multiples of $27.05 to $57.55 and $28.21 to $41.30, respectively.

With respect to the Communications Business, RBC Capital Markets performed a sum-of-the-parts selected public companies analysis of the acquired portions of Fluke Networks Enterprise, Tektronix Communications and Arbor Networks businesses comprising the Communications Business to be acquired in the First Merger. In evaluating the acquired portions of Fluke Networks Enterprise and Tektronix Communications businesses, RBC Capital Markets reviewed, among other things, enterprise values as a multiple of calendar year 2014 and calendar year 2015 estimated unlevered net income of NetScout and the same selected network monitoring companies and selected systems management companies reviewed for the selected public companies analysis of NetScout. In evaluating the Arbor Networks business, RBC Capital Markets reviewed, among other things, enterprise values as a multiple of calendar year 2014 and calendar year 2015 estimated revenue of the following five selected companies in the network security industry, which we refer to as the “selected network security companies” (we collectively refer to the selected companies and the selected network security companies as the “Communications Business selected companies”):

| • |  | A10 Networks, Inc.

| • |  | Barracuda Networks, Inc.

| • |  | F5 Networks, Inc.

| • |  | Fortinet, Inc.

| • |  | Radware Ltd.

The overall low to high calendar year 2014 and calendar year 2015 estimated unlevered net income multiples observed for the selected companies, as noted above, were 15.5x to 34.9x (with a median of 19.7x for the selected network monitoring companies and a median of 20.7x for the selected systems management companies) in the case of calendar year 2014 and 10.7x to 18.8x (with a median of 12.7x for the selected network monitoring companies and a median of 17.9x for the selected systems management companies) in the case of calendar year 2015. Calendar year 2014 and calendar year 2015 estimated unlevered net income multiples observed for NetScout, as noted above, were 21.2x and 18.2x, respectively. The overall low to high calendar year 2014 and calendar year 2015 estimated revenue multiples observed for the selected network security companies were 0.8x to 4.9x (with a median of 3.9x) in the case of calendar year 2014 and 0.7x to 4.2x (with a median of 3.4x) in the case of calendar year 2015. In deriving implied enterprise value reference ranges for the Communications Business, RBC Capital Markets then applied the overall low to high calendar year 2014 and

calendar year 2015 estimated unlevered net income multiples observed for NetScout and the other selected companies to corresponding data of the Fluke Networks Enterprise and Tektronix Communications businesses and the overall low to high calendar year 2014 and calendar year 2015 estimated revenue multiples observed for the selected network security companies to corresponding data of the Arbor Networks business. This analysis indicated approximate aggregate implied enterprise value reference ranges for the Communications Business based on calendar year 2014 estimated unlevered net income and calendar year 2014 estimated revenue multiples of $1.455 billion to $3.850 billion and based on calendar year 2015 estimated unlevered net income and calendar year 2015 estimated revenue multiples of $1.127 billion to $2.634 billion.

Utilizing the approximate implied per share equity value reference ranges derived for NetScout based on the calendar year 2014 and calendar year 2015 estimated unlevered net income multiples described above and the approximate aggregate implied enterprise value reference ranges derived for the Communications Business described above, RBC Capital Markets calculated the following approximate ranges of implied issuable shares, as compared to the merger consideration to be paid by NetScout in the First Merger:

Ranges of Implied Issuable Shares Based On: |  |
2014E Unlevered Net Income and 2014E Revenue |  | 2015E Unlevered Net Income and 2015E Revenue |  | Merger Consideration
22.0 million – 119.8 million |  | 25.8 million – 97.6 million |  | 62.5 million

In addition, RBC Capital Markets noted that the corresponding approximate implied issuable shares would be 22.3 million to 120.1 million shares (based on calendar year 2014 estimated unlevered net income and 2014 estimated revenue) and 26.1 million to 97.9 million shares (based on calendar year 2015 estimated unlevered net income and 2014 estimated revenue) as compared to 62.8 million shares of NetScout common stock issuable in the First Merger, on a fully-diluted basis.

No company used in these analyses is identical to NetScout or the Communications Business. Accordingly, an evaluation of the results of these analyses is not entirely mathematical. Rather, these analyses involve complex considerations and judgments concerning differences in financial and operating characteristics and other factors that could affect the public trading or other values of the companies to which NetScout and the Communications Business were compared.

Discounted Cash Flow Analyses. RBC Capital Markets performed separate discounted cash flow analyses of NetScout and the Communications Business by calculating the estimated present value of the standalone unlevered, after-tax free cash flows that NetScout was forecasted to generate during the fiscal years ending March 31, 2015 through March 31, 2020 based on the NetScout forecasts, and the estimated present value of the standalone unlevered, after-tax free cash flows that the Communications Business was forecasted to generate during the fiscal years ending December 31, 2014 through December 31, 2019 based on the Communications Business forecasts. RBC Capital Markets calculated terminal values for NetScout and the Communications Business by applying to NetScout’s and the Communications Business’ respective terminal year estimated unlevered, after-tax free cash flows a range of perpetuity growth rates of 2.5% to 4.5% in the case of NetScout and 2.0% to 4.0% in the case of the Communications Business. The unlevered, after-tax free cash flows and terminal values were then discounted to present value (as of October 10, 2014) using discount rates ranging from 10% to 11% derived from a weighted average cost of capital calculation. This analysis indicated an approximate implied per share equity value reference range for NetScout of $39.94 to $55.19 and an approximate implied enterprise value reference range for the Communications Business of $1.962 billion to $2.768 billion.

Utilizing the approximate implied per share equity value reference range derived for NetScout common stock and the approximate implied enterprise value reference range derived for the Communications Business described above, RBC Capital Markets calculated the following approximate range of implied issuable shares, as compared to the merger consideration to be paid by NetScout in the First Merger:

Range of Implied Issuable Shares |  | Merger Consideration
35.3 million – 69.0 million |  | 62.5 million

##### Table of Contents

In addition, RBC Capital Markets noted that the corresponding approximate implied issuable shares would be 35.5 million to 69.3 million shares as compared to 62.8 million shares of NetScout common stock issuable in the First Merger, on a fully-diluted basis.

Relative Contribution Analysis. RBC Capital Markets performed a relative contribution analysis of NetScout and the Communications Business in which RBC Capital Markets reviewed the relative contributions of NetScout and the Communications Business to the combined company’s calendar year 2014 and calendar year 2015 estimated revenue, earnings before interest, taxes, depreciation and amortization, which we refer to as “EBITDA,” unlevered net income and net income. Financial data of NetScout was based on the NetScout forecasts (with such data calendarized as necessary) and financial data of the Communications Business was based on the Communications Business forecasts. This analysis indicated overall relative contributions by NetScout of approximately 35.6% to 40.9% and by the Communications Business of approximately 59.1% to 64.4% to the combined company’s calendar year 2014 and calendar year 2015 estimated revenue, EBITDA, unlevered net income and net income.

Utilizing the overall relative contributions of NetScout and the Communications Business to the combined company described above, RBC Capital Markets calculated the following approximate range of implied issuable shares, as compared to the merger consideration to be paid by NetScout in the First Merger:

Range of Implied Issuable Shares |  | Merger Consideration |
53.4 million – 67.0 million |  |  | 62.5 million |

In addition, RBC Capital Markets noted that, based on the merger consideration, the implied pro forma ownership in the combined company of NetScout stockholders and Danaher stockholders (including holders of Danaher restricted stock units) were approximately 40.5% and 59.5%, respectively. RBC Capital Markets also noted that the corresponding approximate implied issuable shares would be 53.7 million to 67.3 million shares as compared to 62.8 million shares of NetScout common stock issuable in the First Merger, on a fully-diluted basis.

Additional Information. RBC Capital Markets observed certain additional information that was not considered part of RBC Capital Markets’ financial analyses with respect to its opinion but was referenced for informational purposes, including, among other things, the following:

• |  | historical trading performance of NetScout common stock during the 52-week period ended October 10, 2014, which reflected low to high closing prices for NetScout common stock during such period of $24.83 to $47.33 per share, as compared to the closing price of NetScout common stock on October 10, 2014 of $41.91 per share;

• |  | publicly available research analysts’ stock price targets for NetScout common stock, which indicated standalone stock price targets for NetScout common stock discounted to present value utilizing a discount rate of 15% based on NetScout’s cost of equity of approximately $29.57 per share to $46.96, as compared to the closing price of NetScout common stock on October 10, 2014 of $41.91 per share; and

• |  | potential pro forma financial effects of the Mergers, both before and after giving effect to potential cost savings, on, among other things, the combined company’s estimated non-GAAP EPS relative to NetScout’s standalone estimated EPS based on the NetScout forecasts and the Communications Business forecasts, which indicated that the Mergers could be accretive to NetScout’s standalone estimated EPS before giving effect to potential cost savings by approximately 0.9% and after giving effect to potential cost savings by approximately 11.9%. The actual results achieved by the combined company may vary from forecasted results and the variations may be material.

Miscellaneous

In connection with RBC Capital Markets’ services as NetScout’s financial advisor, NetScout has agreed to pay RBC Capital Markets an aggregate fee of $11 million, a portion of which was payable upon delivery of RBC Capital Markets’ opinion and $9.5 million of which is contingent upon consummation of the Mergers.

Certain Financial Forecasts Prepared by NetScout

Financial Projections

Neither NetScout nor Danaher, as a matter of course, make public any long-term projections as to future revenues, earnings or other results due to the inherent unpredictability and subjectivity of underlying assumptions and estimates. However, as part of the consideration of the Transactions, Danaher provided unaudited annual results of operations of its Communications Business in calendar year 2011, 2012 and 2013 and preliminary projections for calendar year 2014 and 2015 that were then adjusted by NetScout’s management to reflect $25 million in annualized expense savings as a result of anticipated restructuring activities beginning in the fourth quarter of 2014. After delivery of its preliminary projections to NetScout for 2014 , Danaher subsequently lowered its projections for the Communications Business revenue for calendar year 2014 and NetScout reduced the projected revenue of the Communications Business in 2014 by four percent, which is reflected in the projections. After delivery of its revenue projection for 2015, Danaher communicated to NetScout uncertainty about carrier capital expenditures in fiscal year 2015, which could result in a 2015 revenue forecast for the Communications Business of less than its prior forecast of $891 million. NetScout’s own 2015 revenue forecast for the Communications Business was lower than the Danaher forecast and NetScout did not believe that a further adjustment to the 2015 revenue projection was necessary. These projections are discussed further below.

NetScout’s management prepared financial projections for the Communications Business, as a standalone company, for calendar years 2015 through 2019 by extrapolating results from 2013 and 2014 and making certain assumptions about revenue, potential investments required, operating margin and operating expense growth. Historically, NetScout has publicly provided financial guidance to the investment community for the fiscal year in which it is operating as it relates to key metrics such as revenue and earnings per share, but it does not publicly offer specific long-term guidance on any such metrics. In connection with the Transactions, NetScout prepared financial projections for its existing business, assuming no business combinations or acquisitions, based on consensus Wall Street estimates for fiscal years 2015 and 2016, and by extrapolating those Wall Street estimates for fiscal years 2017 through 2020. The projections do not give pro forma effect to the combination of the Communications Business and NetScout. NetScout’s future financial results and those of the Communications

Business may materially differ from those expressed in the projections due to factors that are beyond NetScout’s ability to control or predict. NetScout cannot assure you that any of these projections will be realized or that its future financial results will not materially vary from the plans and projections. In particular, these projections should not be utilized as public guidance.

The financial projections were not prepared with a view toward public disclosure, or with a view toward compliance with published guidelines of the SEC regarding projections, the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information, or GAAP. The prospective financial information included in this document has been prepared by, and is the responsibility, of the Company’s management.

In light of the foregoing factors and the uncertainties inherent in its financial projections, stockholders are cautioned not to place undue, if any, reliance on these projections.

Certain of the financial projections set forth herein, including earnings before interest, taxes, depreciation and amortization (EBITDA) and earnings before interest and taxes (EBIT), are non-GAAP measures, which means they are financial measures not presented or calculated in accordance with GAAP. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information presented in compliance with GAAP, and Non-GAAP financial measures as used by the Communications Business or NetScout may not be comparable to similarly titled amounts used by other companies.

Near-Term Projections: Relative Contributions

The projections below were used by NetScout’s board of directors to assess the relative contributions of NetScout and the Communications Business to the combined company to be created through the Transactions. As reflected by these near-term projections, NetScout believes the contributions of both NetScout and the Communications Business, support Danaher’s stockholders receiving approximately 59.5% percent of the equity of the combined company and NetScout’s stockholders retaining approximately 40.5% percent of the equity of

Long-Term Projections: Discounted Cash Flows

Management believes the long-term projections are primarily relevant to NetScout’s board of director’s evaluation of the discounted cash flow analyses of the Communications Business on a standalone basis and NetScout on a standalone basis.

Both the NetScout projections for the Communications Business and NetScout as standalone businesses reflect numerous estimates and assumptions with respect to general business, economic, competitive, market and financial conditions and other future events, as well as matters specific to the respective businesses. These projections have not been updated to reflect revised prospects for its business, changes in general business, economic, regulatory, market and financial conditions, or any other transaction or event that has occurred or that may occur and that was not anticipated at the time the projections were prepared. The projections for the Communications Business assume revenue growth of approximately 7% for all of the Communications Business for calendar years 2015 through 2019, although the Tektronix Communications, Arbor Networks and the acquired portions of Fluke Networks Enterprise business lines grow at differing rates within the period and assume that gross margin and operating expense as percentages of revenue remain relatively stable throughout the period. The NetScout projections assume revenue overall growth of approximately 10% at differing rates for fiscal years 2016 through 2020, with the assumption that non-GAAP gross margin and operating expense as percentages of revenue remain relatively stable throughout the period.

Additionally, while the long-term projections focus on the income statement results, the standalone revenue growth assumptions reflected in the financial projections for both the Communications Business and NetScout assume that both NetScout and the Communications Business would make certain investments and/or acquire technology required to successfully launch new or enhanced products, accelerate entry into adjacent market sectors, and drive further customer adoption in key geographic or vertical markets in order to drive the organic and inorganic revenue growth reflected in the assumptions. The acquisition of the Communications Business by NetScout makes those investments and technology acquisitions largely unnecessary and therefore the standalone

projections for each company, which were prepared prior to this acquisition, are not an appropriate basis for accurate projections for the combined company.

The table below presents certain financial metrics reflected in the financial projections for the Communications Business and NetScout on a standalone basis prepared by NetScout management.

As part of the long-term financial projections, NetScout’s management calculated unlevered free cash flow defined as EBIT plus depreciation and amortization expense less capital expenditures and taxes, as well as net changes in working capital, for each of the Communications Business and NetScout on a standalone basis. Unlevered free cash flow differs from the non-GAAP free cash flow that NetScout publicly discloses on a quarterly basis.

Key assumptions for the Communications Business projections included: depreciation expense of $14 million, $16 million, $17 million, $18 million, $19 million and $21 million in calendar years 2014 through 2019 with a terminal value of $23 million (thereby resulting in a terminal value for adjusted EBITDA and tax-effected adjusted EBITA of $277 million and $176 million), respectively; a consistent tax rate of 36.6%; capital expenditures of $16 million will increase by $1 million annually for the next four years and then increase by another $2 million in calendar year 2019; and negative changes in working capital of $15 million in calendar year 2014 will become positive $14 million in calendar year 2015, decline to positive $11 million in calendar year 2016, increase to positive $13 million in calendar year 2017, increase to positive $14 million in calendar year 2018 and finally increase to positive $16 million in calendar year 2019. Accordingly, unlevered free cash flow for the Communications Business is projected as $94 million, $142 million, $149 million, $162 million, $176 million, and $191 million for calendar years 2014 through 2019, respectively, with a terminal value of $192 million.

Key assumptions for the NetScout projections included: depreciation expense of $13 million, $14 million, $16 million, $17 million, $19 million and $21 million in fiscal years 2015 through 2020, respectively; a consistent tax rate of 38.0%; capital expenditures in fiscal year 2015 of $14 million will increase by $2 million annually thereafter; and that positive changes in working capital of $14 million in fiscal year 2015 will decline to

a positive $8 million per year for the next three years, increase slightly to $9 million in fiscal year 2019 and return to $8 million thereafter. Unlevered free cash flow for NetScout is projected at $89 million, $95 million, $104 million, $116 million, $126 million, and $137 million for fiscal years 2015 through 2020, respectively, with a terminal value of $138 million.

Below is a reconciliation of NetScout’s projected non-GAAP adjusted EBITDA with operating income. Reconciliations of the Communications Business non-GAAP metrics to the most applicable GAAP metric were not prepared because no such reconciliation is available without unreasonable efforts.

Post-Acquisition Synergies

Required Investments

As noted above, the long-term projections focus on the income statement results of each of NetScout and the Communications Business on a standalone basis and do not illustrate the capital investment required by either company to achieve these results. In order to achieve the projected revenue growth rates, each business would potentially be required to make investments to successfully launch new or enhanced products, accelerate entry into adjacent market sectors, or drive further customer adoption in key geographic or vertical markets, or all of the above. NetScout’s management believes that its acquisition of the Communication Business will negate the need for NetScout to make further significant investments in order to achieve the revenue growth that was reflected in the long-term projections.

Revenue

NetScout management believes that the combined company will have a broader and more comprehensive portfolio of best-in-class products that roughly doubles NetScout’s existing addressable market from $4 billion to over $8 billion. Just as important, the combined company will have stronger go-to-market capabilities via a larger direct global sales organization that will be complemented by a wider network of value-added resellers around the world. Accordingly, NetScout’s management believes that the combined company will be able to achieve revenue synergies in both the service provider and enterprise markets within the first several years of combined operations. In particular, NetScout expects that in the service provider market, the combined company’s offerings, together with development initiatives to innovate and integrate key features and functionality, will enable the combined company to benefit from new opportunities in its customers’ mobile networks, extend its reach into the radio access portion of its mobile networks, support potential customer initiatives around network virtualization, and drive adoption of its analytics in new departments within its customers. In the enterprise market, NetScout will be better positioned to address a wider range of its customers’ technical and budgetary requirements with opportunities to cross-sell certain offerings into the combined customer base. Additionally, NetScout believes that it can use the combined enterprise customer base to accelerate sales for its cyber security solutions in this market segment. At the same time, NetScout recognizes that a transaction of this magnitude has potential to create slight net revenue dis-synergies in the first year of combined operations primarily arising from customers who may elect to defer purchases or otherwise select a solution from a different vendor, even though NetScout believes that product and customer overlap is minimal in the aggregate. Over the long term, however, NetScout management believes that the combined company will be capable of growing revenue at an approximate compounded annual growth rate of 10 percent.

##### Table of Contents

Cost

The combined company is expected to have a total non-GAAP operating cost base of more than $900 million annually. Once the Transactions are completed, NetScout believes that there will be a number of near and longer-term synergies that will facilitate the elimination of certain costs or otherwise help NetScout limit expense growth across a range of functional areas. During the first year of combined operations, NetScout management’s preliminary estimate is that NetScout will identify, remove and begin realizing run-rate cost synergies of approximately five percent of the combined cost base, or approximately $45 to $55 million. NetScout’s initial estimates of cost synergies were based on NetScout’s prior experience in integrating acquired companies and an analysis of the cost base of NetScout and the Danaher Communications businesses, including materials costs. NetScout’s primary focus during the first year will be to use its purchasing power and extend proven manufacturing techniques in ways that can improve product gross margins while NetScout brings together the combined company’s research and development, sales and marketing, customer service and support, human resources, finance and accounting and other organizations. In addition, NetScout will also seek to consolidate facilities and eliminate unnecessary lease expense in key areas where both companies have historically operated out of separate offices. As a result, NetScout anticipates that its gross margin in the five-year period following the acquisition would improve, as a percentage of total revenue, from 75% to more than 78% of total revenue, which is in line with NetScout’s current gross margins in the 78% to 80% range. Moving into the second year of combined operations, NetScout expects to achieve additional synergies by using common infrastructure platforms, and by eliminating or reducing expenses associated with programs and capabilities already in place as NetScout aligns its go-to-market and related support programs and initiatives. At the same time, NetScout will continue to focus on maintaining a scalable infrastructure and prudently managing its cost structure. Additionally, NetScout will explore opportunities to improve the overall tax efficiency of NetScout’s business by taking advantage of certain operations maintained by the Communications Business in lower tax rate jurisdictions outside of North America.

NetScout believes it will be able to use its purchasing power to improve the gross margins of the Communications Business because NetScout already has lower materials costs than the Communications Business in certain instances. NetScout believes that because the Communications Business products differ from those at other Danaher operating units, the impact of Danaher’s purchasing power on the Communications Business is more modest than it is with respect to other Danaher businesses, and is largely limited to corporate services such as travel, communications, insurance and information technology services. NetScout further believes that the increased size and focus of the combined company will enhance NetScout’s purchasing power and that any increase in the corporate services costs of the Communications Business will be minimal and potentially offset by reductions in NetScout’s corporate services costs as part of the combined company. Projected revenue synergies are based on potential new revenue opportunities in the cyber security market for NetScout utilizing Arbor Networks’ sales force, new enterprise markets for both NetScout and Communications Business products, cross selling opportunities in the service provider market and NetScout leveraging the global marketing network of the Communications Business to grow its international sales.

NetScout believes that the combination of strong revenue growth, operating synergies and prudent cost control will enable NetScout to increase non-GAAP operating profit growth at a higher rate than revenue growth rate. Additionally, by taking steps to improve the combined company’s overall tax efficiency and by continuing to operate with minimal capital requirements, NetScout believes that it will generate substantial free cash flow. Assuming an annual non-GAAP compounded revenue growth rate of 10 percent during the first five-year period after completing the Transaction, and taking into account the aforementioned year-one cost synergies, the potential for additional cost reductions and prudent spending, NetScout believes that the combined company will be capable of increasing its non-GAAP operating margin from NetScout’s operating margin of approximately 25% in fiscal year 2014 by more than five percentage points within five years after completing the Transaction.

Danaher’s Reasons for the Transactions

As discussed in the section of this document entitled “—Background of the Transactions,” from time to time Danaher’s board of directors and senior management have reviewed Danaher’s portfolio of businesses and assets to determine whether changes might be advisable and to consider possible transactions, including possible disposition and merger opportunities, in order to maximize value for Danaher stockholders. As a result of that process, Danaher’s board determined that the separation and distribution of the Communications Business and the merger of the Communications Business with NetScout would be the best way to realize the full value of the Communications Business and enable Danaher to focus on its remaining businesses in accordance with its corporate strategy.

In reaching its decision to approve the Merger Agreement, the Distribution Agreement and the Transactions, Danaher’s board of directors considered the following material factors in supporting its decision:

| • |  | the value creation expected to result from combining the Communications Business with NetScout, and the ability of Danaher stockholders to own approximately 59.5% of NetScout on a fully-diluted basis after giving effect to the Transactions and participate in the future upside of the combined company;

| • |  | the complementary nature of the product and service offerings of the Communications Business and those of NetScout, the combination of which is expected to enhance the offerings of both companies to customers and solidify the position of the combined company as a premier, global communications and data solutions provider;

| • |  | the resources of the Communications Business outside of the United States, and the opportunities that such resources will present for NetScout’s operations to expand to other markets as a result of the Transactions;

| • |  | the expectation that the Separation, the Distribution and the Mergers generally would result in a tax-efficient disposition of the Communications Business for Danaher and Danaher’s stockholders, while a sale of the Communications Business for cash generally would result in a taxable disposition for Danaher;

| • |  | NetScout’s business prospects and expected synergies after giving effect to the proposed acquisition of the Communications Business;

| • |  | the reports of Danaher’s senior management regarding their due diligence review of NetScout’s business; and

| • |  | the review by the board of directors of the structure and terms of the Merger Agreement, the Distribution Agreement and the Transactions, including the parties’ representations, warranties and covenants, the conditions to their respective obligations and the termination provisions, as well as the likelihood of consummation of the Transactions and the board’s evaluation of the likely time period necessary to close the Transactions.

The fourth and seventh bullets above are considered to be benefits to Danaher while the first, second, third, fifth and sixth bullets above are considered to be benefits to Danaher stockholders who are being offered the opportunity to receive shares of NetScout common stock upon completion of the Distribution and thereby participate in the future upside potential of the combined company.

In the course of its deliberations, the Danaher board of directors also considered the following material risks and negative factors in supporting its decision:

| • |  | the risk that all conditions to the parties’ obligations to complete the Transactions will not be satisfied or waived, which while not expected could cause the Transactions to not be completed;

| • |  | because the consideration to be received by Danaher’s stockholders in the Transactions consists of a fixed number of shares of NetScout common stock, the value of the NetScout common stock to be

117

##### Table of Contents

| received in the Mergers could fluctuate, perhaps significantly, based on a variety of factors including general stock market conditions and the performance of NetScout’s business;

| • |  | risks relating to integrating the Communications Business with NetScout’s current operations, including the potential loss of key employees, and the potential effects on the value of the NetScout common stock to be received in the mergers;

| • |  | the risk that the Transactions do not qualify as tax-free transactions under Sections 355 or 368 of the Code, which could result in the stockholders of Danaher having significant tax liability;

| • |  | the risks relating to the combined company maintaining and renewing relationships with pre-existing customers, channel partners, suppliers and other third-parties of both the Communications Business and NetScout, which relationships may be affected by customer, channel partner, supplier or third-party preferences or public attitudes about the Transactions;

| • |  | the effect of divesting the Communications Business pursuant to the Transactions on Danaher’s future earnings per share and cash flows from operating activities; and

| • |  | risks of the type and nature described under the section of this document entitled “Risk Factors.”

Danaher’s board of directors considered all of these factors as a whole and, on balance, concluded that they supported a favorable determination to approve the Merger Agreement, the Distribution Agreement and the Transactions. The foregoing discussion of the information and factors considered by the board of directors of Danaher is not exhaustive. In view of the wide variety of factors considered by the board in connection with its evaluation of the Transactions and the complexity of these matters, the board did not consider it practical to, nor did it attempt to, quantify, rank or otherwise assign relative weights to the specific factors that it considered in reaching its decision. The board evaluated the factors described above, among others, and reached a consensus to approve the Merger Agreement, the Distribution Agreement and the Transactions. In considering the factors described above and any other factors, individual members of the board may have viewed factors differently or given different weight or merit to different factors.

Interests of Certain Persons in the Transactions

As of [—], 2015, Danaher’s directors and executive officers owned approximately [—]% of the outstanding shares of Danaher’s common stock and, as of such date, NetScout’s directors and executive officers owned approximately [—]% of the outstanding shares of NetScout common stock. None of NetScout’s or Newco’s executive officers will receive any severance or other compensation as a result of the Transactions. The directors and officers of Danaher, Newco and NetScout will receive no extra or special benefit that is not shared on a pro rata basis by all other Newco common unit holders and NetScout stockholders in connection with the Transactions. As with all holders of shares of Danaher common stock, if a director or officer of Danaher, Newco or NetScout owns shares of Danaher common stock, directly or indirectly, such person may participate in the Distribution on the same terms as other holders of shares of Danaher common stock. As of [—], 2015, Danaher owned approximately 2.9% of the outstanding shares of NetScout common stock.

In connection with the execution of the Merger Agreement, Steven M. Rales, Chairman of the Board of Directors of Danaher, and Mitchell P. Rales, Chairman of the Executive Committee of Danaher, delivered separate letters to NetScout, in which they each agreed that if the Distribution was structured as an exchange offer, they would not exchange more than the number of shares of Danaher common stock in an exchange offer for Newco common units that would result (after taking into consideration any Newco common units distributed in a pro-rata spin off to Danaher stockholders in the event the exchange offer is not fully subscribed) in his receiving more than 5% of the issued and outstanding shares of NetScout common stock after giving effect to the closing under the Merger Agreement.

Material U.S. Federal Income Tax Consequences of the Transactions

This section describes the material U.S. federal income tax consequences of the Transactions. This section is based on the Code, the Treasury regulations promulgated under the Code, and interpretations of such authorities by the courts and the IRS, all as they exist as of the date of this proxy statement and all of which are subject to change, possibly with retroactive effect. The discussion assumes that the Separation, the Distribution and the Mergers will be consummated in accordance with the Transaction Agreements and as further described in this proxy statement.

This section is limited to holders of NetScout common stock that are U.S. holders, as defined below, that hold their shares of NetScout common stock as a capital asset within the meaning of Section 1221 of the Code. Further, this section does not discuss all tax considerations that may be relevant to holders of NetScout common stock in light of their particular circumstances, nor does it address the consequences to holders of NetScout common stock subject to special treatment under the U.S. federal income tax laws, such as tax-exempt entities, partnerships (including entities treated as partnerships for U.S. federal income tax purposes), persons who acquire their shares of NetScout common stock pursuant to the exercise of employee stock options or otherwise as compensation, financial institutions, insurance companies, dealers or traders in securities, and persons who hold their shares of NetScout common stock as part of a straddle, hedge, conversion, constructive sale, synthetic security, integrated investment or other risk-reduction transaction for U.S. federal income tax purposes. This section does not address any U.S. federal estate, gift or other non-income tax consequences or any state, local or foreign tax consequences, or the consequences of the Medicare tax on net investment income. Holders of NetScout common stock should consult their tax advisors as to the particular tax consequences to them of the Transactions.

For purposes of this section, a U.S. holder is a beneficial owner of NetScout common stock that is, for U.S. federal income tax purposes:

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

| • |  | a corporation, or other entity taxable as a corporation for U.S. federal income tax purposes, created or organized under the laws of the United States or any state or political subdivision thereof;

| • |  | an estate, the income of which is subject to United States federal income taxation regardless of its source; or

| • |  | a trust, if (i) a court within the United States is able to exercise primary jurisdiction over its administration and one or more U.S. persons have the authority to control all of its substantial decisions, or (ii) in the case of a trust that was in existence on August 20, 1996 and treated as a domestic trust under the law in effect prior to that time, a valid election is in place under applicable Treasury regulations.

If a partnership (including any entity treated as a partnership for U.S. federal income tax purposes) holds shares of NetScout common stock, the tax treatment of a partner in the partnership generally will depend upon the status of the partner and the activities of the partnership. A partner of a partnership holding shares of NetScout common stock should consult its tax advisor regarding the tax consequences of the Transactions.

Treatment of the Distribution

Because NetScout stockholders will not participate in the Distribution, NetScout stockholders generally will not recognize gain or loss upon the Distribution. NetScout stockholders should consult their own tax advisors regarding the tax consequences to them of the Distribution.

The consummation of the Distribution is conditioned upon the receipt by Danaher of an opinion from Skadden to the effect that, among other things, the Distribution will qualify as tax-free to Danaher and holders of

119

##### Table of Contents

Danaher common stock who participate in the Distribution for U.S. federal income tax purposes under Sections 355 and 368(a)(1)(D) of the Code. Danaher also intends to seek a ruling from the IRS regarding certain issues relevant to the qualification of the Distribution and certain other aspects of the Separation for tax-free treatment for U.S. federal income tax purposes.

Although the IRS ruling, if received, will generally be binding on the IRS, the continuing validity of such ruling will be subject to the accuracy of factual representations and assumptions made in the ruling request. Also, as part of the IRS’ general policy with respect to rulings on spin-off and split-off transactions (including the Distribution), the IRS will not rule on the overall qualification of the transaction for tax-free treatment, but instead only on certain significant issues related thereto. As a result of this IRS policy, Danaher will obtain the opinion of counsel described above. The opinion will be based upon various factual representations and assumptions, as well as certain undertakings made by Danaher and Newco. If any of those factual representations or assumptions are untrue or incomplete in any material respect, any undertaking is not complied with, or the facts upon which the opinion will be based are materially different from the facts at the time of the Distribution, the Distribution may not qualify for tax-free treatment. Opinions of counsel are not binding on the IRS. As a result, the conclusions expressed in the opinion of counsel could be challenged by the IRS, and if the IRS prevails in such challenge, the Distribution may not qualify for tax-free treatment.

The Distribution and certain aspects of the Separation could be taxable to Danaher if Newco, its unit holders, NetScout or NetScout’s stockholders were to engage in a Disqualifying Action. In such cases, under the Tax Matters Agreement, Newco and NetScout will be required to indemnify Danaher against any taxes resulting from the Distribution or certain aspects of the Separation that arise as a result of a Disqualifying Action. If Danaher were to recognize gain on the Distribution or certain aspects of the Separation for reasons not related to a Disqualifying Action by Newco or NetScout, Danaher would not be entitled to be indemnified under the Tax Matters Agreement. If Newco or NetScout were required to indemnify Danaher as a result of the Distribution or certain aspects of the Separation being taxable, this indemnification obligation would likely be substantial and could have a material adverse effect on NetScout, including with respect to its financial condition and results of operations.

Treatment of the Mergers

NetScout will not recognize any gain or loss for U.S. federal income tax purposes as a result of the Mergers. Because NetScout stockholders will not participate in the Mergers, NetScout stockholders generally will not recognize gain or loss upon the Mergers. NetScout stockholders should consult their own tax advisors regarding the tax consequences to them of the Mergers.

The consummation of the Mergers is conditioned upon the receipt by Danaher of an opinion from Skadden to the effect that, among other things, the Mergers will qualify as a tax-free “reorganization” within the meaning of Section 368(a) of the Code. The opinion will be based upon various factual representations and assumptions, as well as certain undertakings made by Danaher and Newco. If any of those factual representations or assumptions are untrue or incomplete in any material respect, any undertaking is not complied with, or the facts upon which the opinion will be based are materially different from the facts at the time of the Mergers, the Mergers may not qualify for tax-free treatment. Opinions of counsel are not binding on the IRS. As a result, the conclusions expressed in the opinion of counsel could be challenged by the IRS, and if the IRS prevails in such challenge, the Mergers may not qualify for tax-free treatment.

THE FOREGOING IS A SUMMARY OF THE MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE DISTRIBUTION AND THE MERGERS UNDER CURRENT LAW AND FOR GENERAL INFORMATION ONLY. THE FOREGOING DOES NOT PURPORT TO ADDRESS ALL U.S. FEDERAL INCOME TAX CONSEQUENCES OR TAX CONSEQUENCES THAT MAY ARISE UNDER THE TAX LAWS OR THAT MAY APPLY TO PARTICULAR CATEGORIES OF SHAREHOLDERS.

Accounting Treatment and Considerations of the Mergers

ASC 805, Business Combinations, requires the use of the acquisition method of accounting for business combinations. In applying the acquisition method, it is necessary to identify both the accounting acquiree and the accounting acquiror. In a business combination effected through an exchange of equity interests, such as the Mergers, the entity that issues the interests (NetScout in this case) is generally the acquiring entity. In identifying the acquiring entity in a combination effected through an exchange of equity interests, however, all pertinent facts and circumstances must be considered, including the following:

| • |  | The relative voting interests of significant shareholders and the ability of any of those shareholders to exercise control over the consolidated entity after the Transactions. In this case, it was determined that the shareholder bases of both entities are dispersed such that no single shareholder or group of related shareholders would control the entity after the Transactions.

| • |  | The composition of the governing body of NetScout after the Transactions. In this case, the board of directors of NetScout immediately following the Mergers will consist of the members of the board of directors of NetScout immediately prior to the consummation of the Mergers. In addition, as of the consummation of the Mergers, NetScout will increase the size of its board of directors by one member, and one individual selected by Danaher (which individual is currently anticipated by NetScout and Danaher to be James A. Lico, Danaher’s Executive Vice President) will be appointed to fill the vacancy and will, subject to the fiduciary duties of NetScout’s board of directors, be nominated for re-election at the expiration of such director’s initial term.

| • |  | The composition of the senior management of NetScout after the Transactions. In this case, NetScout’s executive officers following the Mergers will consist of NetScout’s executive officers immediately prior to the Mergers.

NetScout’s management has determined that NetScout will be the accounting acquiror in the Mergers based on the facts and circumstances outlined above and the detailed analysis of the relevant GAAP guidance. Consequently, NetScout will apply acquisition accounting to the assets acquired and liabilities assumed of Newco upon consummation of the Mergers. Upon consummation of the Mergers, the historical financial statements will reflect only the operations and financial condition of NetScout.

Regulatory Approvals

Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), and the rules promulgated under the HSR Act by the Federal Trade Commission, the parties must file notification and report forms with the U.S. Federal Trade Commission and the Antitrust Division of the U.S. Department of Justice and observe specified waiting period requirements before consummating the Mergers. NetScout and Danaher each filed the requisite notification and report forms with the Federal Trade Commission and the Antitrust Division on October 24, 2014. NetScout withdrew its filing on November 24, 2014, and refiled on November 26, 2014 to provide the antitrust agencies more time to review the transaction.

On December 24, 2014, NetScout received a second request from the U.S. Department of Justice. The effect of the second request is to extend the waiting period imposed by the HSR Act until 30 days after both NetScout and Danaher have substantially complied with the request, unless that period is extended voluntarily by the parties or terminated sooner by the U.S. Department of Justice.

Federal Securities Law Consequences; Resale Restrictions

NetScout common stock issued in the Mergers will not be subject to any restrictions on transfer arising under the Securities Act, except for shares issued to any Danaher stockholder who may be deemed to be an “affiliate” of Newco for purposes of Rule 145 under the Securities Act.

In connection with the Distribution, Danaher may be deemed to be an “underwriter” within the meaning of Section 2(a)(11) of the Securities Act.

No Appraisal or Dissenters’ Rights

None of NetScout, Merger Sub, Merger Sub II, Danaher or Newco stockholders will be entitled to exercise appraisal rights or to demand payment for their shares in connection with the Transactions.

THE MERGER AGREEMENT

The following is a summary of the material provisions of the Merger Agreement, which summary is qualified in its entirety by the Merger Agreement, a copy of which is attached as Annex A to this document. Stockholders of NetScout are urged to read the Merger Agreement in its entirety. This summary of the Merger Agreement has been included to provide NetScout stockholders with information regarding its terms. The rights and obligations of the parties are governed by the express terms and conditions of the Merger Agreement and not by this summary or any other information included in this document. This summary of the Merger Agreement is not intended to provide any other factual information about NetScout, Merger Sub, Merger Sub II, Danaher or Newco following the consummation of the Mergers. Information about NetScout, Merger Sub, Merger Sub II, Danaher or Newco can be found elsewhere in this document and in the documents incorporated by reference into this document. See also “Where You Can Find More Information: Incorporation by Reference.”

The Mergers

Under the Merger Agreement and in accordance with the DGCL and the DLLCA, at the effective time of the First Merger, Merger Sub will merge with and into Newco. As a result of the First Merger, the separate corporate existence of Merger Sub will terminate and Newco will continue as the surviving company and as a wholly-owned subsidiary of NetScout and will succeed to and assume all the rights, powers and privileges and be subject to all of the obligations of Merger Sub in accordance with the DGCL and the DLLCA. The certificate of formation and limited liability company operating agreement of Newco in effect immediately prior to the First Merger will be amended and restated in their entirety following the consummation of the Merger. Immediately following the First Merger, Newco (as the surviving entity of the First Merger) will merge with and into Merger Sub II. As a result of the Second Merger, the separate corporate existence of Newco will terminate and Merger Sub II will continue as the surviving company and as a wholly-owned subsidiary of NetScout and will succeed to and assume all the rights, powers and privileges and be subject to all of the obligations of Newco in accordance with the DLLCA.

Closing; Effective Time

Under the terms of the Merger Agreement, the closing of the Mergers will take place at 10:00 a.m., Eastern Time, no later than the second business day after the date on which the conditions precedent to the Mergers are satisfied or waived (other than those to be satisfied at the closing of the Mergers), unless otherwise agreed upon by NetScout and Danaher.

Under the terms of the Distribution Agreement, the date of the Distribution will be selected by Danaher’s board of directors or its designees. The closing of the Separation will occur at 12:01 a.m. Eastern Time on the date of the Distribution. See also “Description of the Separation and Distribution Agreement.”

At the closing of the First Merger, NetScout and Danaher will cause to be filed a certificate of merger with the Secretary of State of the State of Delaware to effect the First Merger. The First Merger will become effective at the time of filing of such certificate of merger or at such later time as NetScout and Danaher may agree and provide in the certificate of merger. Immediately after the effective time of the First Merger, NetScout will cause to be filed a certificate of merger with the Secretary of State of the State of Delaware to effect the Second Merger. The Second Merger will become effective at the time of filing of such certificate of merger or at such later time as NetScout and Danaher may agree and provide in the certificate of merger.

Merger Consideration

The Merger Agreement provides that, at the effective time of the First Merger, each issued and outstanding Newco common unit (except Newco common units held by Danaher, NetScout or any of their respective subsidiaries or by Newco in its treasury) will be automatically converted into a number of shares of NetScout

123

##### Table of Contents

common stock equal to (x) 62.5 million shares of NetScout common stock plus the product of (A) 1.46 multiplied by (B) the number of shares of NetScout common stock issued in any acquisition by NetScout prior to the effective time of the First Merger divided by (y) the aggregate number of Newco common units issued and outstanding immediately prior to the effective time of the First Merger. The calculation of the merger consideration as set forth in the Merger Agreement is expected to result, prior to the elimination of fractional shares, in Newco’s members immediately prior to the Merger collectively holding approximately 59.5% of the outstanding equity interests of NetScout on a fully-diluted basis immediately following the First Merger and NetScout’s stockholders immediately prior to the First Merger collectively holding approximately 40.5% of such equity interests on a fully-diluted basis.

No fractional shares of NetScout common stock will be issued pursuant to the First Merger. Any holder of Newco common units who would otherwise be entitled to receive a fraction of a share of NetScout common stock (after aggregating all fractional shares issuable to such holder) shall, in lieu of such fraction of a share, be paid in cash the dollar amount (rounded to the nearest whole cent), after deducting any required withholding taxes, on a pro rata basis, without interest, determined by multiplying such fraction by the closing price of a share of NetScout common stock on NASDAQ on the last business day prior to the closing of the First Merger.

Exchange of Newco Common Units

Prior to the effective time of the First Merger, NetScout will issue and cause to be deposited with the exchange agent non-certificated shares of NetScout common stock represented by book entry authorizations for the benefit of the Danaher stockholders who received Newco common units in the Distribution and for distribution in the First Merger upon conversion of the Newco common units.

At the effective time of the First Merger, all issued and outstanding Newco common units will be converted into the right to receive shares of NetScout common stock as described above under “—Merger Consideration.” Upon receipt of a duly executed letter of transmittal and other customary documents, the exchange agent will distribute the shares of NetScout common stock to each person who was entitled to receive Newco common units in the Distribution. Each person entitled to receive Newco common units in the Distribution will be entitled to receive in respect of such Newco common units a certificate or book-entry authorization representing the number of whole shares of NetScout common stock that such holder has the right to receive pursuant to the First Merger (and cash in lieu of fractional shares of NetScout common stock as described above under “—Merger Consideration”) (and any dividends or other distributions and other amounts as described below under “—Distributions With Respect to Shares of NetScout Common Stock After the Effective Time of the First Merger”).

Distribution With Respect to Shares of NetScout Common Stock After the Effective Time of the First Merger

No dividend or other distributions declared or made after the effective time of the First Merger with respect to NetScout common stock with a record date after the effective time of the First Merger will be paid with respect to any shares of NetScout common stock unless such holder exchanges such Newco common unit in accordance with the Merger Agreement. NetScout is required under the Merger Agreement to deposit all such amounts with the exchange agent.

Termination of the Distribution Fund

Any portion of the amounts deposited with the exchange agent under the Merger Agreement that remains undistributed to the former members of Newco on the one-year anniversary of the effective time of the First Merger will be delivered to NetScout upon demand, and any former members of Newco who have not received shares of NetScout common stock as described above may thereafter look only to NetScout for payment of their claim for NetScout common stock and any dividends, distributions or cash in lieu of fractional shares with respect to NetScout common stock (subject to any applicable abandoned property, escheat or similar law).

Conversion of Shares in the Second Merger

Immediately after the effective time of the First Merger, both Newco (as the surviving entity in the First Merger) and Merger Sub II will be wholly-owned subsidiaries of NetScout. At the effective time of the Second Merger, each limited liability company interest of Newco outstanding immediately prior to the effective time of the Second Merger shall be canceled and shall cease to exist and no consideration shall be delivered in exchange therefor and each limited liability company interest in Merger Sub II outstanding immediately prior to the effective time of the Second Merger shall remain unchanged and continue to remain outstanding as a limited liability company interest in Merger Sub II. At the effective time of the Second Merger, NetScout will continue as the sole member of Merger Sub II (the surviving entity of the Second Merger) and Merger Sub II shall continue without dissolution.

Adjustment Amount

Under the Merger Agreement, promptly following the delivery of the Audited Financial Statements, Danaher was required to deliver to NetScout a statement setting forth a calculation of the Operating Profit derived from the audited financial statements of the Communications Business for the year ended December 31, 2013 included in the Audited Financial Statements. In the event that the Operating Profit was less than the amount set forth on the schedules to the Merger Agreement, then Danaher shall pay to NetScout an amount in cash equal to the product of (x) such shortfall multiplied by (y) 13.1; provided, however, that in no event shall such payment exceed $150 million. Because the Operating Profit reflected in the Audited Financial Statements exceeded the amount specified in the Merger Agreement, there was no payment required.

Post-Closing NetScout Board of Directors and Officers

The Merger Agreement provides that the NetScout board of directors will take all actions necessary such that, effective as of the effective time of the First Merger, one person selected by Danaher and approved by NetScout will be elected to the NetScout board of directors. In accordance with the Merger Agreement, this individual will also, subject to the fiduciary duties of NetScout’s board of directors, be nominated for re-election to the board of directors of NetScout at NetScout’s 2015 annual meeting of stockholders.

Additionally, the executive officers of NetScout immediately prior to the consummation of the First Merger are expected to be the executive officers of NetScout immediately following the consummation of the Mergers.

Stockholders Meeting

Under the terms of the Merger Agreement, NetScout is required to call a meeting of its stockholders for the purpose of voting upon the issuance of shares of NetScout’s common stock in the Mergers and related matters as promptly as practicable following the date on which the SEC has cleared the NetScout proxy statement and, if required by the SEC as a condition to the mailing of the NetScout proxy statement, the registration statement of NetScout has been declared effective. NetScout will ask its stockholders to vote on this matter at the special meeting of NetScout stockholders by delivering the NetScout proxy statement to its stockholders in accordance with applicable law and its organizational documents. NetScout is required to call such a stockholders meeting for the purpose of voting upon the issuance of shares of NetScout common stock in the Mergers and related matters unless the Merger Agreement is terminated, regardless of whether the board of directors of NetScout has made a Change in Recommendation (as defined below).

##### Table of Contents

and, except as set forth in Article IV of the Distribution Agreement, none of the representations and warranties survive the closing of the Mergers. The Merger Agreement does not contain any post-closing indemnification obligations with respect to these matters; provided, however pursuant to the Distribution Agreement, certain of Danaher’s and Newco’s representations in the Merger Agreement related title to and sufficiency of the Newco Assets and the Newco IP survive for a period of 12 months after the effective time of the First Merger.

Under the Merger Agreement, a material adverse effect means, with respect to Newco or NetScout, as applicable, any effect, change, claim, event or circumstance that, considered will all other effects, changes, claims, events or circumstances either (a) would prevent or materially impair such party from complying with its obligations under the Merger Agreement or from consummating the transactions contemplated by the Merger Agreement and the other Transaction Documents or (b) is or would reasonably be expected to be or to become materially adverse to, or has or would reasonably be expected to have or result in a material adverse effect on the business, financial condition or results of operations of such party and its subsidiaries taken as a whole. However, with respect to clause (b), any change, development, event, occurrence, effect or state of facts arising out of or resulting from any of the following will not be deemed either to constitute, or be taken into account in determining whether there is, a material adverse effect:

| • |  | conditions generally affecting the industry in which NetScout or Newco, as the case may be, competes or the U.S. or global economy as a whole, to the extent that such conditions do not have a disproportionate impact on NetScout and its subsidiaries (the “NetScout Companies”) or Newco and its subsidiaries after giving effect to the transactions and transfer of assets and liabilities as set forth in the Distribution Agreement (the “Newco Companies”), as the case may be, taken as a whole, relative to other companies in the industry in which such companies operate;

| • |  | changes in the trading price or trading volume of NetScout common stock or Danaher common stock, as the case may be (it being understood, however, that, generally any effect, change, claim, event or circumstance giving rise to or contributing to such changes in the trading price or trading volume of NetScout common stock or Danaher common stock, as the case may be, may give rise to a material adverse effect and may be taken into account in determining whether a material adverse effect has occurred);

| • |  | changes in GAAP (or any interpretations of GAAP) or laws applicable to NetScout Companies or Newco Companies, as the case may be, to the extent that such conditions do not have a disproportionate impact on NetScout Companies or Newco Companies, as the case may be, taken as a whole, relative to other companies in the industry in which the NetScout Companies or the Newco Companies, as the case may be operate;

| • |  | the failure to meet public estimates or forecasts of revenues, earnings of other financial metrics, in and of itself, or the failure to meet internal projections, forecasts or budgets of revenues, earnings or other financial metrics, in and of itself (it being understood, however, that, generally, any effect, change, claim, event or circumstance giving rise to or contributing to any such failure may give rise to a material adverse effect and may be taken into account in determining whether a material adverse effect has occurred);

| • |  | any stockholder or derivative litigation arising from or relating to the Merger Agreement or the transactions contemplated by the Merger Agreement or the other Transaction Documents;

| • |  | effects, changes, claims, events or circumstances resulting directly from the announcement or pendency of the Merger Agreement or the transactions contemplated by the Merger Agreement or the

127

SEC Filings

The parties agreed to prepare appropriate documents, including this document, a registration statement on Form S-4 of NetScout, and a registration statement on Form S-4 and S-1 (or such other appropriate registration form or forms to be designated by Danaher) of Newco and to file them with the SEC, and NetScout and Newco, as the case may be, have agreed to use their reasonable best efforts to have these documents cleared by the SEC and have their respective registration statements declared effective by the SEC as promptly as reasonably practicable after such filings or at such other time as Danaher, Newco and NetScout may agree.

NetScout is required under the terms of the Merger Agreement to mail this document to its stockholders as promptly as practicable after the SEC clears this document and, if required by the SEC, the registration statements described above are declared effective.

If Danaher elects to complete the Distribution by way of an exchange offer, NetScout, Danaher and Newco are required under the terms of the Merger Agreement to prepare, and Danaher is obligated to file with the SEC, a Schedule TO as promptly as practicable after the date on which the registration statement with respect to the Separation and the Distribution is declared effective and to the extent such filing is required by applicable law.

Regulatory Matters

The Merger Agreement provides that each party to the Merger Agreement will use reasonable best efforts to take or cause to be taken all actions necessary or advisable to consummate the Mergers as soon as practicable, including to prepare and file all filings (if any) and give all notices (if any) required to be made and given by such party in connection with the Mergers and the other transactions contemplated by the Merger Agreement and

131

##### Table of Contents

the other Transaction Documents; (ii) obtain each third party consent (if any) required to be obtained (pursuant to any applicable law or contract, or otherwise) by such party in connection with the Mergers or any of the other transactions contemplated by the Merger Agreement and the other Transaction Documents (including NetScout providing a guarantee of Newco’s obligations reasonably necessary to obtain such consents); and (iii) lift any restraint, injunction or other legal bar to the Mergers. Each party to the Merger Agreement has also agreed to file all notices, reports and other documents required to be filed by such party with any governmental body with respect to the Mergers and to submit promptly any additional information requested by any such governmental body. NetScout and Danaher have agreed to prepare and file (x) the notifications required under the HSR Act and (y) any applicable mandatory foreign competition act filings in connection with the Mergers. NetScout and Danaher each shall use its reasonable best efforts to cause the expiration or early termination of any waiting period under the HSR Act, and NetScout and Danaher shall each (i) cooperate with the other party in connection with any filing or submission and in connection with any investigation or other inquiry, including any proceeding initiated by a private party, (ii) promptly supply the other party with any information which may be required in order to effectuate notices, reports, documents or other filings with any governmental body required to be made pursuant to the HSR Act and any applicable mandatory foreign competition act filings (the “Antitrust Filings”); and (iii) promptly supply any additional information which reasonably may be required by any governmental body in connection with Antitrust Filings or which the parties may reasonably deem appropriate.

Notwithstanding the foregoing, neither NetScout, Danaher, Merger Subs nor Newco shall have any obligation under the Merger Agreement (except as specifically set forth in the Merger Agreement or any other Transaction Document) to divest or agree to divest (or cause any of its subsidiaries to divest or agree to divest) any of its respective material businesses, material product lines or material assets, or to take or agree to take (or cause any of its subsidiaries to take or agree to take) any other material action or agree (or cause any of its subsidiaries to agree) to any material limitation or material restriction on any of its respective material businesses, material product lines or material assets, except as would not, or as would not reasonably be expected to, involve the divestiture of assets that generated in the aggregate more than 10% of the combined gross revenues of the Newco and its subsidiaries and the NetScout Companies for the 12 months ending June 27, 2014 (it being understood that no such action shall be considered for purposes of determining whether a material adverse effect has occurred or is reasonably likely to occur and the parties shall not be required to take any of the foregoing actions in this paragraph unless the effectiveness of such action is conditioned on the closing of the Mergers). Notwithstanding the foregoing, no such divestiture of assets may occur if such divestiture would constitute a Disqualifying Action (as defined in the Tax Matters Agreement).

No Solicitation

The Merger Agreement contains detailed provisions restricting NetScout’s or Danaher’s ability to seek an alternative transaction. With respect to Danaher, this restriction is only with respect to Newco and its subsidiaries, the Communications Business and the Newco Assets. Under these provisions, NetScout and Danaher have each agreed that it and its subsidiaries will not, and it will use reasonable best efforts to cause its and its subsidiaries’ officers, directors, employees, agents and representatives not to:

| • |  | solicit, initiate, knowingly encourage or knowingly facilitate the making, submission or announcement of any acquisition proposal or acquisition inquiry;

| • |  | furnish any information regarding any of the NetScout Companies, on the one hand, or the Communications Business, Newco Assets or the Newco Companies, on the other hand, as applicable, to any person in connection with or in response to an acquisition proposal or acquisition inquiry;

| • |  | except in limited circumstances, approve, endorse or recommend, or propose publicly to approve, endorse or recommend, an acquisition proposal;

| • |  | engage in discussions or negotiations with any person relating to any acquisition proposal or acquisition inquiry;

132

##### Table of Contents

| • |  | except as specifically described below, not directly or indirectly withdraw or modify (or propose to by withdrawn or modified) the Board Recommendation in a manner adverse to Danaher (a “Change in Recommendation”).

Notwithstanding the foregoing, the NetScout board of directors, at any time prior to obtaining stockholder approval of the issuance of shares of NetScout common stock in the First Merger, may effect a Change in Recommendation under the following circumstances:

##### Table of Contents

| determines in good faith, after having consulted with its outside legal counsel, that, in light of such Superior Offer, a failure to make a Change in Recommendation would be reasonably likely to constitute a breach of the fiduciary duties of the NetScout board of directors to NetScout stockholders under applicable law; or

| • |  | if other than in connection with or as a result of the making of an acquisition proposal or an acquisition inquiry with respect to NetScout, a material development or change in circumstances that was not known or reasonably foreseeable to the NetScout board of directors on October 12, 2014 occurs or arises after October 12, 2014, which material development or change in circumstances becomes known to the NetScout board of directors prior to the approval of the issuance of shares of NetScout common stock pursuant to the First Merger by the NetScout stockholders (such material development or change in circumstances being referred to as an “Intervening Event” (it being understood that that in no event shall (i) any action taken by NetScout or Danaher pursuant to and in compliance with its obligations under the Merger Agreement related to the Antitrust Filings, and the consequences of any such action or (ii) the receipt, existence of or terms of an acquisition proposal with respect to NetScout or the consequences thereof constitute an Intervening Event); (A) the NetScout board of directors determines in its good faith judgment, after consulting with its financial advisor and outside legal counsel that an Intervening Event has occurred; (B) the NetScout board of directors does not effect, or cause NetScout to effect, a Change in Recommendation at any time within 4 business days after Danaher receives written notice from NetScout that the NetScout board of directors has determined that an Intervening Event requires the NetScout board of directors to effect, or cause NetScout to effect, a Change in Recommendation (provided, a new notice shall be required with respect to any change in circumstances and a new notice period of 3 business days shall begin); (C) during such applicable period, if requested by Danaher, NetScout engages in good faith negotiations, and directs its financial advisors and outside legal advisors to, engage in good faith negotiations, with Danaher to amend this Agreement in such a manner that obviates the need for the NetScout board of directors to effect, or cause NetScout to effect, a Change in Recommendation as a result of such Intervening Event; and (D) the NetScout board of directors determines in good faith, after having consulted with its outside legal counsel, that, in light of such Intervening Event, a failure to make a Change in Recommendation would be reasonably likely to constitute a breach of the fiduciary duties of the NetScout board of directors to NetScout’s stockholders under applicable law.

The Merger Agreement provides that NetScout is not prohibited from taking and disclosing to its stockholders a position required by Rule 14e-2(a) or Rule 14d-9 promulgated under the Exchange Act and no disclosure that the NetScout board of directors may determine in good faith (after consultation with outside counsel) that it or NetScout is required to make under applicable law will constitute a violation of the Merger Agreement. A “stop, look and listen” or similar communication of the type contemplated by Rule 14d-9(f) of the Exchange Act shall not be deemed a Change in Recommendation if the NetScout board of directors expressly reaffirms the Board Recommendation within 5 business days of the public announcement of any applicable acquisition proposal.

Assumption of Liabilities

At the same time as the transfer of the Communications Assets to Newco or one or more Newco Subs (with certain exceptions), Newco or one or more Newco Subs will assume, perform and fulfill when due and, to the extent applicable, comply with certain liabilities of the Communications Business described below and certain other liabilities described in the schedules to the Distribution Agreement. The Communications Business liabilities, which are referred to herein as the “Communications Liabilities” (which Newco will assume), specifically exclude the Excluded Liabilities (as defined below), but include, with certain exceptions:

| • |  | liabilities that are expressly contemplated by the Distribution Agreement, including certain liabilities specified on the schedules to the Distribution Agreement, or any Ancillary Agreement as liabilities to be retained, assumed or retired by Newco or any Newco Sub, and all agreements, obligations and liabilities of any person at Newco or any Newco Sub under the Distribution Agreement, the Merger Agreement or any Ancillary Agreement;

| • |  | liabilities that relate to (i) the conduct and operation of the Communications Business, (ii) the conduct and operation of any other business conducted by Newco or any subsidiary of Newco after the Separation Time, (iii) the ownership, operation or use of any Communications Assets and (iv) any warranty or similar obligation of the Communications Business;

| • |  | with respect to the Communications Business and the Communications Assets, subject to certain exceptions, liabilities that relate to (x) any violation or alleged violation of environmental laws, (y) any loss of life or injury due to asbestos exposure and (z) the off-site disposal, storage, transport, discharge or release of hazardous materials;

| • |  | liabilities under the Newco contracts and the allocated portion of any Newco Shared Contract or any other contract that is assigned to Newco or any Newco Sub;

| • |  | liabilities that relate to leases for the Communications Assets;

| • |  | customer deposits held by Danaher or any subsidiary of Danaher that are related to the provision of service by the Communications Business;

| • |  | accounts payable that relate to the construction or investment in the Communications Assets as of the effective time of the First Merger;

| • |  | tax liabilities that are allocated to Newco or the Newco Subs pursuant to the Tax Matters Agreement (See “Additional Material Agreements—Tax Matters Agreement”); and

| • |  | other than Excluded Liabilities, liabilities of Danaher or any subsidiary of Danaher (including Newco and the Newco Subs) that relate to the ownership or use of the Communications Assets or the operation or the conduct of the Communications Business.

The Distribution Agreement also identifies specific liabilities that will not be assumed by Newco or any Newco Sub as part of the Separation, which are referred to herein as the “Excluded Liabilities,” including the following liabilities:

| • |  | liabilities that relate to (A) any loss of life or injury due to asbestos exposure and (B) the off-site disposal, storage, transport, discharge or release of hazardous materials that relates to (x) the ownership or use of the Excluded Assets or (y) activities of Danaher or any subsidiary of Danaher (other than Newco or any Newco Sub) at or affecting the Communications Assets, other than as included in the Communications Liabilities above;

| • |  | liabilities for indebtedness other than indebtedness solely between or among Newco and any Newco Sub;

| • |  | liabilities, costs or expenses incurred by or on behalf of Newco or any Newco Sub at or prior to the effective time of the First Merger in connection with the Transactions contemplated by the Distribution Agreement, the Merger Agreement or any Ancillary Agreement;

143

##### Table of Contents

| • |  | tax liabilities that are allocated to Danaher or the Danaher group pursuant to the Tax Matters Agreement (See “Additional Material Agreements—Tax Matters Agreement”);

| • |  | liabilities that relate to certain contingent or deferred obligations and employee benefit payments; and

| • |  | liabilities that are expressly contemplated by the Distribution Agreement or any Ancillary Agreement as liabilities to be retained or assumed by Danaher or any subsidiary of Danaher (other than Newco or any Newco Sub), and all liabilities of Danaher or any subsidiary of Danaher (other than Newco or any Newco Sub) under the Distribution Agreement or any Ancillary Agreement.

Cash Transfers

If any cash or cash equivalents remain in Newco or any Newco Sub immediately following the Separation Time, Newco shall promptly transfer, or cause to be transferred, such amount of cash and cash equivalents (including any interest earned thereon) to Danaher or its designee.

Third Party Consents

As promptly as practicable after the signing of the Distribution Agreement and for a period of eighteen (18) months following the closing of the Mergers, the parties to the Distribution Agreement will cooperate and each use reasonable best efforts to transfer or reissue to Newco or a Newco Sub all the permits used, or held for use, primarily in the Communications Business and to obtain all consents and governmental approvals required to consummate the transfer of the Communications Assets and Communications Liabilities. No party is required to make any material payments, incur a material liability or grant any material accommodation to any third party to obtain such consents or approvals, although Danaher and NetScout have each agreed to bear half the costs associated with obtaining such consents.

Deferred Assets; Subsequent Transfers

If the transfer of any Communications Assets or Excluded Assets requires any consents or approvals which have not been obtained at the Separation Time, the transfer of such asset will automatically be deferred (but will still be considered a Communications Asset or Excluded Asset, as applicable). The party retaining the deferred asset will hold the asset in trust for the benefit of the party entitled to the asset until the asset is transferred. During such time, the parties will use reasonable best efforts to make arrangements to place the party entitled to such asset in the same position as if the asset had been transferred as originally contemplated. As soon as the legal impediment to the transfer of the asset in question is removed, or the necessary consents and/or governmental approvals are obtained, the transfer will be effected pursuant to the terms of the Distribution Agreement and/or applicable Ancillary Agreement. The obligations related to the transfer of deferred assets will survive for the duration of the term of the contract, if any, giving rise to the consent requirement.

Shared Contracts

Danaher will use reasonable best efforts to separate and cause the applicable member of the Newco group to enter into new agreements with the applicable counterparties to the Danaher Shared Contracts prior to the Separation Time. Upon such separation of a Danaher Shared Contract, the separated contract that is related to the Communications Business will be a Newco contract and the other separated contract will be an Excluded Asset. To the extent that Danaher is unable or the applicable counterparties are unwilling to enter into agreements with respect to any Danaher Shared Contract, Danaher (or the applicable subsidiary of Danaher) will partially assign the Communications Business functions to Newco in the manner agreed to by the parties. In the event that such partial assignment is not permitted by the terms of the applicable Danaher Shared Contract or consented to by the applicable counterparty, Danaher will use reasonable best efforts to provide for an alternative arrangement so that the applicable member of the Newco group will have the benefits of such Danaher Shared Contract as though it had been partially assigned. Danaher (or the applicable subsidiary of Danaher) is not required to make any

144

##### Table of Contents

supplemental payments to any third party when providing such an alternative arrangement. Newco will cooperate with Danaher when entering into any new agreement or partial assignment. The obligations related to Danaher’s use of reasonable best efforts to separate and assign Danaher Shared Contracts will terminate on the eighteen (18) month anniversary of the closing of the Mergers, and the obligations related to Danaher’s use of reasonable best efforts to provide for alternative arrangements will survive for the duration of the term of the applicable contract.

Newco will use reasonable best efforts to separate and cause the applicable member of the Danaher group to enter into new agreements with the applicable counterparties to the Newco Shared Contracts prior to the Separation Time. Upon such separation of a Newco Shared Contract, the separated contract that is related to the Communications Business will be a Newco contract and the other separated contract will be an Excluded Asset. To the extent that Newco is unable or the applicable counterparties are unwilling to enter into agreements with respect to any Newco Shared Contract, Newco (or the applicable subsidiary of Newco) will partially assign the non-Communications Business functions to Danaher in the manner agreed to by the parties. In the event that such partial assignment is not permitted by the terms of the applicable Newco Shared Contract or consented to by the applicable counterparty, Newco will use reasonable best efforts to provide for an alternative arrangement so that the applicable member of the Danaher group will have the benefits of such Newco Shared Contract as though it had been partially assigned. Newco (or the applicable subsidiary of Newco) is not required to make any supplemental payments to any third party when providing such an alternative arrangement. Danaher will cooperate with Newco when entering into any new agreement or partial assignment. The obligations related to Newco’s use of reasonable best efforts to separate and assign Newco Shared Contracts will terminate on the eighteen (18) month anniversary of the closing of the Mergers, and the obligations related to Newco’s use of reasonable best efforts to provide for alternative arrangements will survive for the duration of the term of the applicable contract.

Novations of Newco Contracts

Upon Danaher’s request, the parties will use reasonable best efforts to obtain the novation of any Newco contract specified by Danaher. Danaher (or the applicable subsidiary of Danaher) is not required to make any payments to any third party when obtaining such novations. The obligations related to the novation of Newco contracts will terminate on the eighteen (18) month anniversary of the closing of the Mergers.

Termination of Intercompany Agreements

Effective as of the Distribution Date, Danaher and Newco will terminate all contracts (including any guarantee obligations) between Danaher and any subsidiary of Danaher (excluding Newco and any Newco Sub), on the one hand, and Newco and any subsidiary of Newco, on the other hand, except (i) the Merger Agreement, the Distribution Agreement, and the Ancillary Agreements, (ii) any contracts or intercompany accounts solely between members of the Newco group, (iii) any contract to which any person other than the parties to the Distribution Agreement (or their affiliates) are a party, (iv) any contracts between a subsidiary of Danaher that is in the business of selling or buying products or services to or from third parties and a member of the Newco group (and that is primarily related to the provision of such products or services and was or is entered into in the ordinary course of business) and (v) any contract that the Distribution Agreement, the Merger Agreement, or the Ancillary Agreements expressly contemplate will survive the Distribution Date. All loans between Danaher or any subsidiary of Danaher, on the one hand, and Newco or any subsidiary of Newco, on the other hand, likewise will be terminated before the Distribution Date.

Guarantees

Following the closing, if the parties were unable to novate, assign or replace any Danaher guarantees prior to the closing, Newco will (i) continue to use its reasonable best efforts to novate, assign or replace such Danaher guarantees with NetScout as guarantor and (ii) indemnify, defend and hold harmless Danaher and its affiliates

145

##### Table of Contents

against, and reimburse Danaher and its affiliates for, any losses Danaher and its affiliates incurred because any such Danaher guarantee is called upon and Danaher or its affiliate is required to make any material payment under any such Danaher guarantee. The obligations related to Newco’s use of reasonable best efforts do not require Newco to take any action that would be reasonably expected to expose it or any subsidiary of Newco to any material incremental expenses or losses of benefits.

Resignations

At or prior to the Distribution Date, Danaher will use its reasonable best efforts to cause each employee and director of Danaher or any subsidiary of Danaher who will not be employed by Newco or a Newco Sub to resign, effective no later than the Distribution Date, from all boards of directors or similar governing bodies of Newco or any Newco Sub, and from all positions as officers of Newco or any Newco Sub.

Conditions to the Separation

The obligations of Danaher to effect the Separation pursuant to the Distribution Agreement are subject to fulfillment (on or before the effective time of the First Merger) or waiver (which waiver will require the written consent of NetScout unless the Merger Agreement has been terminated), at or prior to the Separation Date, of each condition to each party’s respective obligations to effect the Mergers as described in the Merger Agreement.

The Distribution

The Distribution Agreement provides that Danaher may elect, in its sole discretion, to effect the Distribution in the form of either (i) a dividend of Newco common units to Danaher stockholders on a pro rata basis, referred to as a spin-off, (ii) an offer by Danaher to exchange Newco common units for currently outstanding shares of Danaher’s common stock, referred to as a split-off exchange offer or (iii) a combination of a spin-off and a split-off exchange offer. Danaher must advise NetScout of the form of the Distribution at least thirty (30) business days before the anticipated date of the closing of the Mergers.

| • |  | each material governmental approval required in connection with the Internal Restructuring or any transaction contemplated by the Plan of Reorganization has been obtained and is in full force and effect; and

146

##### Table of Contents

NetScout Guarantee

Following the effective time of the First Merger, NetScout guarantees the obligations of Newco and the Newco Subs to Danaher under the Distribution Agreement and the Ancillary Agreements.

Additional Covenants

Each of Danaher and Newco have undertaken specified covenants in the Distribution Agreement restricting the conduct of their respective businesses and committing them to take specified actions. You are urged to read carefully the sections of the Distribution Agreement entitled “Access to Information” and “Additional Agreements.” The more significant of these covenants discuss:

| • |  | confidentiality and access by each party to confidential information (including making witnesses available) in the possession or control of the other party;

| • |  | treatment by each party of privileged information; and

| • |  | the removal of tangible Communications Assets located at any facilities of Danaher or any subsidiaries of Danaher (other than Newco or any subsidiary of Newco).

Insurance

Prior to the effective time of the First Merger, Newco, the Communications Assets and the Communications Business will continue to be covered under insurance policies of Danaher or the subsidiaries of Danaher. Following the effective time of the First Merger, Newco, the Communications Assets and the Communications Business will no longer be covered under the insurance policies of Danaher or the subsidiaries of Danaher. Newco or any subsidiary of Newco will have the right to access occurrence-based coverage (to the extent such coverage exists) for claims asserted after the effective time of the First Merger but arising out of an occurrence prior to the effective time of the First Merger.

Following the Distribution Date, members of the Newco group will have no rights or claims with respect to any captive insurance company of Danaher or any of its affiliates or any fronted insurance program maintained by Danaher or any of its affiliates that is not a “risk transfer” insurance program.

Danaher will maintain directors’ and officers’ liability and fiduciary liability insurance coverage for no less than six years following the effective time of the First Merger.

Mutual Releases; Indemnification

Release of Pre-Distribution Date Claims

Subject to specified exceptions, Newco, on the one hand, and Danaher, on the other hand, agreed to release the other party and its respective subsidiaries, stockholders, directors, partners, managers, managing members, officers, agents or employees from any and all liabilities, whether arising under any contract or by operation of law or otherwise, including in connection with the Transactions and all other activities to implement the Separation:

| • |  | existing or arising from any acts or events occurring or failing to occur or alleged to have occurred or to have failed to occur on or before the effective time of the Mergers; or

| • |  | arising from any conditions existing or alleged to have existed on or before the effective time of the Mergers.

The mutual release is subject to specified exceptions set forth in the Distribution Agreement, including with respect to any indemnification to which a director, officer, manager, employee or agent of Danaher, Newco or any of their subsidiaries is entitled, if such individual was entitled to a right of indemnification under the organizational documents of Newco or any subsidiary of Newco or pursuant to a contract.

147

##### Table of Contents

Indemnification

Except as otherwise provided in the Merger Agreement or any Ancillary Agreement, Newco and each member of the Newco group, on a joint and several basis, agreed to indemnify Danaher from and against all losses, liabilities, damages, penalties, judgments, assessments, costs and expenses that relate to any of the following, whether arising before or after the effective time of the First Merger:

| • |  | the Communications Liabilities assumed by Newco;

| • |  | any breach by Newco or any Newco Sub of any obligations under the Distribution Agreement or the Ancillary Agreements after the effective time of the Mergers; and

| • |  | any breach by NetScout or any of its affiliates of any covenant of NetScout under the Merger Agreement, which by its terms is to be performed after the effective time of the Mergers.

Except as otherwise provided in the Merger Agreement or any Ancillary Agreement, Danaher has agreed to indemnify Newco from and against all losses, liabilities, damages, penalties, judgments, assessments, costs and expenses that relate to any of the following, whether arising before or after the effective time of the Mergers:

| • |  | the Excluded Liabilities;

| • |  | any breach by Danaher or any subsidiary of Danaher (other than Newco or any subsidiary of Newco) of any obligations under the Distribution Agreement or the Ancillary Agreements on or after the Separation Time;

| • |  | any breach by Danaher or any of its affiliates of any covenant of Danaher under the Merger Agreement, which by its terms is to be performed after the effective time of the Mergers; and

| • |  | any breach of the representations and warranties set forth in certain sections of the Merger Agreement with respect to title to, and sufficiency of, the Communications Assets.

Survival

The ability to make a claim for indemnification related to the breach of any representation and warranty made by Danaher will terminate after the end of the applicable survival period under the terms of the Merger Agreement as described in “The Merger Agreement—Survival of Representations, Warranties and Agreements.” In the event that notice of any claim for indemnification related to the breach of any representation and warranty made by Danaher is given within the applicable survival period, the representations and warranties that are the subject of such indemnification claim will survive until such time as such claim is finally resolved.

Baskets and Caps

Danaher’s obligation to indemnify the Newco indemnitees for losses related to a breach of specified representations and warranties made by Danaher in the Merger Agreement with respect to title to, and sufficiency of, the Communications Assets is subject to certain limitations. With respect to such losses, no indemnification will be made by Danaher with respect to any claim until the aggregate amount of all such losses exceeds $5,000,000, at which point the Newco Indemnitees are entitled to indemnification only for such losses in excess of $5,000,000. Only individual claims or series of related claims involving such losses in excess of $100,000 will be included in the calculation to determine whether the $5,000,000 deductible amount has been met. In no event will the obligation of Danaher to indemnify Newco indemnitees for losses related to breaches of specified representations and warranties made by Danaher in the Merger Agreement with respect to title to, and sufficiency of, the Communications Assets exceed $250,000,000 in the aggregate.

Indemnification Obligations Net of Proceeds from Third Parties

Any liability that is subject to indemnification or contribution pursuant to the Distribution Agreement will be net of any proceeds received by the indemnitee from any third party for indemnification for such liability

148

##### Table of Contents

(referred to as third-party proceeds). An indemnitee must use commercially reasonable efforts to seek to collect or recover any third-party proceeds in connection with any liability for which the indemnitee seeks indemnification or contribution.

Amendment and Waiver

The Distribution Agreement may be amended and any provision may be waived only by writing signed by both parties, in the case of an amendment, or the party waiving the provision, in the case of a waiver. In addition, unless the Merger Agreement shall have been terminated in accordance with its terms, any such amendment or waiver shall be subject to the written consent of NetScout.

Termination

Prior to the closing of the Mergers, the Distribution Agreement will terminate without any further action upon termination of the Merger Agreement. In the event of such termination, no party will have any further liability to the other party, except as provided in the Merger Agreement.

OTHER AGREEMENTS

The following is a summary of the material provisions of the Employee Matters Agreement, the Tax Matters Agreement, the Transition Services Agreement, the Trademark License Agreement, the IP License Agreement, the DBS License Agreement, the Lease Agreement and the Voting Agreement. This summary is qualified in its entirety by reference to the complete text of the Employee Matters Agreement and the Tax Matters Agreement, copies of which are attached hereto as annexes D and E, respectively. The rights and obligations of the parties are governed by the express terms and conditions of these agreements and not by this summary or any other information included in this document. You are urged to read the agreements carefully and in their entirety.

Employee Matters Agreement

In connection with the proposed Transactions, Danaher, NetScout and Newco have negotiated an employee matters agreement, that, among other things, allocates between the parties the pre-and post-closing liabilities in respect of the employees and independent contractors of the Communications Business transferring to Newco (including liabilities in respect of Danaher’s employee benefit plans) and establishes certain required treatment of the transferring employees by NetScout after the closing.

Identification of Newco Employees and Newco Independent Contractors

Transferring employees and independent contractors of the Communications Business, respectively referred to as “Newco Employees” and “Newco Independent Contractors,” will generally consist of:

| • |  | each employee or independent contractor of Danaher’s Tektronix Communications and Arbor Networks businesses;

| • |  | each employee or independent contractor of Danaher’s Fluke Network’s business who transfers by operation of law, or is determined to be either:

| • |  | primarily dedicated to the Communications Business in the ordinary course; or

| • |  | required for the ongoing operation of the Communications Business.

Danaher employees meeting the criteria above who are not actively at work at the time of the closing of the Mergers as a result of a disability or an approved leave of absence will become Newco Employees only if and when they return to active employment within six months after the closing of the Mergers (or such longer period as may be required by law).

The parties will establish an integration team to identify which employees and independent contractors of Danaher’s Fluke Networks Enterprise business should be treated as Newco Employees and Newco Independent Contractors, with the goal of providing Newco with sufficient operational and management employees to operate and manage the Communications Business. If the integration team is unable to agree prior to the closing of the Mergers whether an employee or independent contractor of Danaher’s Fluke Networks Enterprise business should be a Newco Employee or Newco Independent Contractor, the Senior Vice President-Human Resources of Danaher will make the final determination.

General Allocation of Liabilities

Newco will generally assume all liabilities in respect of Newco Employees and Newco Independent Contractors, whether arising before or after the closing of the Mergers, as well as all liabilities arising before the closing of the Mergers in respect of individuals who are not Newco Employees or Newco Independent Contractors but where the liability arose while the individual was employed by or providing substantial services to the Communications Business. Danaher will retain all other liabilities, including all liabilities in respect individuals who are not Newco Employees or Newco Independent Contractors (except as described in the

150

##### Table of Contents

preceding sentence) and all liabilities arising from the transfer of Newco Employees and Newco Independent Contractors in connection with the proposed Transactions (other than transfer-related liabilities that arise out of Newco’s or NetScout’s failure to comply with any of their respective obligations under the terms of the Employee Matters Agreement).

Newco will continue to maintain or assume all obligations under Danaher’s collective bargaining agreements to the extent they apply to Newco Employees and as required by law. If the terms of a collective bargaining agreement require that any assets or liabilities be retained by Danaher or transferred to Newco in a manner other than as set forth in the Employee Matters Agreement, the terms of the applicable collective bargaining agreement will govern.

Post-Closing Compensation and Benefits

For 12 months after the closing of the Mergers, NetScout will generally provide each Newco Employee with a base salary or hourly wage that is at least equal to the base salary or hourly wage provided to the employee immediately before the closing of the Mergers and a target annual cash bonus opportunity that is no less favorable than the target annual cash bonus opportunity in effect for the employee immediately before the closing of the Mergers.

NetScout will also generally provide severance benefits to any Newco Employee not covered by a collective bargaining agreement who is terminated within 12 month after the closing of the Mergers that are no less favorable than the severance benefits the Newco Employee would have received upon a termination of his or her employment immediately before the closing of the Mergers.

In addition, from a period beginning within a reasonable period of time following the closing of the Mergers through the end of the calendar year in which the closing occurs, NetScout will use its reasonable best efforts to provide each Newco Employee with health, welfare and retirement benefits that are no less favorable than the health, welfare and retirement benefits provided by NetScout to its similarly situated employees in the applicable jurisdiction.

Service Crediting

Subject to certain exceptions, Newco Employees generally will be credited by NetScout for all of their pre-closing service with Danaher for purposes of eligibility, vesting and determination of level of benefits under any NetScout benefit arrangement in which Newco Employees participate after the closing of the Mergers.

Treatment of Defined Benefit Pension Plans

Newco Employees will generally cease participating in and accruing benefits under Danaher’s defined benefit pension plans as of the closing of the Mergers. NetScout will not be required to establish or maintain a U.S. defined benefit pension plan following the closing of the Mergers for any Newco Employee, and Danaher will retain all assets and liabilities for Newco Employees relating to Danaher’s U.S. defined benefit pension plan. If required by law in the applicable non-U.S. jurisdiction, NetScout will use its reasonable efforts to establish or maintain a non-U.S. defined benefit pension plan for Newco Employees who participated in a Danaher non-U.S. defined benefit pension plan immediately before the closing of the Mergers with terms substantially similar to the terms of the applicable Danaher non-U.S. defined benefit pension plan as in effect immediately before the closing of the Mergers, and Danaher will transfer assets and liabilities related to Newco Employees under the applicable Danaher non-U.S. defined benefit pension plan to the applicable NetScout non-U.S. defined benefit pension plan. If the non-U.S. pension liabilities transferred by Danaher exceed the assets transferred by Danaher, Danaher is obligated to transfer an amount of cash to NetScout equal to the difference between the non-U.S. pension liabilities transferred and the assets transferred.

151

##### Table of Contents

Treatment of Defined Contribution Retirement Plans

Newco Employees will cease participating in the Danaher 401(k) plan in which the employees participate as of the closing of the Mergers, and each Newco Employee will become fully vested in his or her account balance under the plan as of the closing of the Mergers. Each Newco Employee will be permitted to make rollover contributions from the Danaher 401(k) plan in which the employee participates to NetScout’s 401(k) plan.

Newco Employees will generally cease participating in and accruing benefits under Danaher’s non-U.S. defined contribution retirement plans as of the closing of the Mergers. If required by law in the applicable non-U.S. jurisdiction, NetScout will establish or maintain a non-U.S. defined contribution retirement plan for Newco Employees who participated in a Danaher non-U.S. defined contribution retirement plan immediately before the closing of the Mergers with terms no less favorable than the terms of the applicable Danaher non-U.S. defined contribution retirement plan as in effect immediately before the closing of the Mergers, and Danaher will transfer assets and liabilities related to Newco Employees under the applicable Danaher non-U.S. defined contribution retirement plan to the applicable NetScout non-U.S. defined contribution retirement plan.

Treatment of Welfare Benefit Plans

Newco Employees will generally cease participating in and accruing any benefits under Danaher’s welfare benefit plans as of the closing of the Mergers. NetScout will use its reasonable best efforts to establish or maintain health and welfare benefits plans providing medical, dental, vision, disability and life insurance coverage for Newco Employees with terms and conditions that are fully equivalent to the health and welfare benefits provided by NetScout to its similarly situated employees as of the closing of the Mergers. Danaher generally will retain liabilities for welfare and fringe benefit claims incurred before the closing of the Mergers, and NetScout generally will assume liabilities for welfare and fringe benefit claims incurred on and after the closing of the Mergers.

NetScout will credit each Newco Employee with the amount of accrued but unused vacation time and other paid time off benefits attributable to pre-closing service at Danaher. However, NetScout may require that any carry-over amounts in excess of what could have been carried over under the applicable NetScout paid time off plan be used by December 31 of the year following the year in which the closing of the Mergers occurs.

Treatment of Nonqualified Deferred Compensation Plan

Newco Employees will cease active participation in Danaher’s nonqualified deferred compensation plan as of the closing of the Mergers. NetScout will have no obligation to establish a nonqualified deferred compensation plan for Newco Employees, and Danaher will retain all assets and liabilities with respect to Danaher’s nonqualified deferred compensation plan, including any liabilities with respect to Newco Employees.

Treatment of Danaher Equity Incentive Awards

Each option to purchase shares of Danaher common stock that is held by a Newco Employee and is vested and exercisable immediately before the closing of the Mergers or is scheduled to vest on or before August 4, 2015 will generally remain outstanding for 90 days following the later of the closing date of the Mergers or the date the option becomes vested and exercisable. Each restricted stock unit relating to shares of Danaher common stock that is held by a Newco Employee and is unvested immediately before the closing of the Mergers, but is scheduled to vest on or before August 4, 2015, will continue to vest and be settled in accordance with its terms. Each of these Danaher stock options and Danaher restricted stock units may be equitably adjusted by Danaher if determined by the Danaher board of directors to be necessary to reflect the impact of the proposed Transactions on the value of shares of Danaher common stock. Danaher does not believe that any adjustments will be made in the event that the exchange offer, if applicable, is fully subscribed.

152

##### Table of Contents

All stock options and restricted stock units relating to shares of Danaher common stock that are held by a Newco Employee and that are not vested immediately before the closing of the Mergers or scheduled to vest on or before August 4, 2015, will generally be cancelled by Danaher immediately before the closing of the Mergers and replaced by NetScout with a cash retention award and restricted stock units relating to shares of NetScout common stock in respect of the value (determined in accordance with the methods described below) of the cancelled Danaher stock options and Danaher restricted stock units held by the employee before the closing of the Mergers. The value of each cancelled Danaher stock option, referred to herein as the Cancelled Danaher Option Value, will be equal to the spread value of the cancelled Danaher stock option, or, if greater, the value obtained by dividing the total number of shares of Danaher common stock subject to the cancelled Danaher stock option by 2.5 and multiplying the resulting number of shares by the per share closing price of Danaher common stock trading on the “regular way” basis on the New York Stock Exchange on the day immediately prior to the closing date of the Mergers. The value of each cancelled Danaher restricted stock unit, referred to herein as the Cancelled Danaher Restricted Stock Unit Value, is equal to the total number of shares of Danaher common stock subject to the Danaher restricted stock unit multiplied by the per share closing price of Danaher common stock trading on the “regular way” basis on the New York Stock Exchange on the day immediately prior to the closing date of the Mergers. Together, the Cancelled Danaher Option Value and the Cancelled Danaher Restricted Stock Unit Value are referred to herein as the Newco Employee’s Cancelled Danaher Equity Award Value.

The cash retention award each Newco Employee will receive in respect of the value of the employee’s cancelled Danaher equity awards will be equal to one half of the employee’s Cancelled Danaher Equity Award Value and will become payable on the later of the first anniversary of the closing date of the Mergers or August 4, 2016, subject to the employee’s continued employment with NetScout through the applicable vesting date. Danaher will reimburse NetScout for the amount of the cash retention payments (net of any applicable employment taxes and deductions).

The number of restricted stock units relating to shares of NetScout common stock each Newco Employee will receive in respect of the value of the employee’s cancelled Danaher equity awards will be equal to the number obtained by dividing one half of the employee’s Cancelled Danaher Equity Award Value by the per share closing price of NetScout common stock trading on the “regular way” basis on NASDAQ on the closing date of the Mergers, provided that the maximum aggregate value of all restricted stock units relating to shares of NetScout common stock that will be granted to Newco Employees in respect of their cancelled Danaher equity awards will not exceed $15 million. If the value of the restricted stock units to be granted to Newco Employees in respect of their cancelled Danaher equity awards would otherwise exceed $15 million, the applicable reduction in the number of restricted stock units to be so granted will be applied to each applicable Newco Employee on a pro rata basis. These restricted stock units relating to shares of NetScout common stock will be subject to the terms and conditions of the applicable NetScout stock plan and the applicable award agreement provided by NetScout.

However, in the event the abovementioned treatment of the cancelled Danaher equity awards results in adverse tax consequences or compliance issues to the parties or any Newco employees, different treatment may apply as agreed between Danaher and NetScout.

Treatment of Annual Bonus Programs

Danaher will pay or reimburse NetScout for the bonus amounts that Newco Employees could have received for the fiscal year in which the closing of the Mergers occurs based on projected actual performance for the full year as determined by Danaher in good faith as of the closing date of the Mergers, but pro-rated for the portion of the year ending on the closing date of the Mergers. Danaher will also pay or reimburse NetScout for any accrued but unpaid bonus amounts that NetScout pays to Newco Employees in respect of the fiscal year ending immediately prior to the closing of the Mergers.

Danaher Retention Plan

Danaher may, in its sole discretion, adopt a cash retention plan for the benefit of certain Newco Employees based on the achievement of specified continued employment requirements or other vesting conditions identified by Danaher.

Employee Stock Purchase Plan

Each Newco Employee located in the United States will be eligible to participate in NetScout’s employee stock purchase plan on the same basis as similarly situated employees of NetScout as of the first offering date under such plan following the closing date of the Mergers.

Miscellaneous

The indemnification and dispute resolution procedures in the Employee Matters Agreement are generally consistent with those under the Distribution Agreement. As noted above, however, there are special dispute resolution procedures for the identification of Newco Employees and Newco Independent Contractors.

The Employee Matters Agreement is governed by Delaware law.

Tax Matters Agreement

Allocation of taxes. Newco intends to enter into the Tax Matters Agreement with Danaher and NetScout immediately prior to the Distribution that will govern the parties’ respective rights, responsibilities and obligations with respect to tax liabilities and benefits, tax attributes, the preparation and filing of tax returns, the control of audits and other tax proceedings and other matters regarding taxes. In general, under the agreement:

| • |  | Danaher will be responsible for (i) any U.S. federal income taxes imposed on Danaher’s U.S. federal consolidated group for any period, (ii) any U.S. federal, state, local or foreign taxes (and any related interest, penalties or audit adjustments) imposed on Newco and/or any of its subsidiaries for any periods or portions thereof ending on or prior to the effective date of the Distribution, and (iii) any transfer taxes arising from the separation or the Distribution.

| • |  | Newco (and, following the effective time of the First Merger, NetScout) will be responsible for any U.S. federal, state, local or foreign taxes (and any related interest, penalties or audit adjustments) imposed on Newco and/or any of its subsidiaries for any periods or portions thereof beginning after the effective date of the Distribution.

Neither party’s obligations under the agreement will be limited in amount or subject to any cap. The agreement will also assign responsibilities for administrative matters, such as the filing of returns, payment of taxes due, retention of records and conduct of audits, examinations or similar proceedings. In addition, the agreement provides for cooperation and information sharing with respect to tax matters.

Danaher will generally be responsible for preparing and filing any tax return that includes Danaher or any of its subsidiaries (as determined immediately after the Distribution), including those that also include Newco and/or any of its subsidiaries. Newco will generally be responsible for preparing and filing any tax returns that include only Newco and/or any of its subsidiaries.

The party responsible for preparing and filing a given tax return will generally have primary authority to control tax contests related to any such tax return. Newco will generally have exclusive authority to control tax contests with respect to tax returns that include only Newco and/or any of its subsidiaries.

Preservation of the tax-free status of certain aspects of the Separation. Newco and Danaher intend for the Distribution and certain related transactions to qualify as a reorganization pursuant to which no gain or loss is

154

##### Table of Contents

recognized by Danaher or its stockholders for U.S. federal income tax purposes under Sections 355, 368(a)(1)(D) and related provisions of the Code. In addition, Newco and Danaher intend for certain other aspects of the Separation to qualify for tax-free treatment under U.S. federal, state and local tax law and/or foreign tax law.

Danaher is seeking a ruling from the IRS regarding certain issues relevant to the qualification of the Distribution and certain other aspects of the Separation for tax-free treatment for U.S. federal income tax purposes. The request for the IRS Ruling was filed on November 17, 2014. In addition, Danaher expects to receive opinions from its outside tax advisors regarding the tax-free status of the Distribution and certain other aspects of the Separation. In connection with the ruling and the opinions, Newco and Danaher have made and will make certain representations regarding the past and future conduct of their respective businesses and certain other matters.

Newco will also agree to certain covenants that contain restrictions intended to preserve the tax-free status of the Distribution and certain other aspects of the Separation. Newco may take certain actions prohibited by these covenants only if Danaher receives a private letter ruling from the IRS or Newco obtains and provides to Danaher an opinion from a U.S. tax counsel or accountant of recognized national standing to the effect that such action would not jeopardize the tax-free status of these transactions. Newco will be barred from taking any action, or failing to take any action, where such action or failure to act adversely affects the tax-free status of these transactions, for all relevant time periods. In addition, during the time period ending two years after the effective date of the Distribution these covenants will include specific restrictions on Newco, including the following:

| • |  | certain restrictions on issuing or selling stock or other securities (including securities convertible into Newco stock but excluding certain compensatory arrangements);

| • |  | redeeming or repurchasing its stock or stock rights, except to the extent consistent with guidance issued by the IRS;

| • |  | certain restrictions on selling assets outside the ordinary course of business;

| • |  | discontinuing the active conduct of the Communications Business; and

| • |  | entering into any other corporate transaction (apart from the Mergers) which, when combined with the Mergers, would cause Newco to undergo a 50% or greater change in its stock ownership.

As of the effective time of the First Merger, NetScout will be subject to the same obligations and restrictions imposed on Newco under the Tax Matters Agreement, including, without limitation, the tax-related covenants discussed above, and for the avoidance of doubt any restrictions applicable to Newco shall also apply to NetScout mutatis mutandis.

Newco and NetScout will generally agree to indemnify Danaher and its affiliates against any and all tax-related liabilities incurred by them relating to the Distribution and certain other aspects of the Separation to the extent caused by an acquisition of Newco’s stock or assets or by any other action undertaken by Newco or NetScout. This indemnification provision will apply even if Danaher has permitted Newco or NetScout to take an action that would otherwise have been prohibited under the tax-related covenants described above.

Transition Services Agreement

In connection with the Transactions, Danaher and Newco will enter into a transition services agreement, referred to herein as the Transition Services Agreement, effective as of the closing of the First Merger. In order to facilitate the transition of the Communications Business to Newco (which, after the First Merger, will be a wholly-owned subsidiary of NetScout), under the transition services agreement Danaher and its affiliates will provide Newco, with specified support services and other assistance for a limited time following the closing of the Mergers.

155

##### Table of Contents

The Transition Services Agreement also addresses certain matters with respect to the provision of such services, including the management of the relationship between the parties, the use of and access to each other’s records, confidentiality and proprietary rights.

The initial term of the Transition Services Agreement is currently contemplated to be for a period commencing at the Effective Time and ending at 11:59 p.m. Eastern Time on March 31, 2016, unless earlier terminated as provided in the Transition Services Agreement, although the individual terms of certain services may expire prior to the end of the term of the Transition Services Agreement itself. Newco will not have the option of extending the services provided under the Transition Services Agreement.

Newco will generally be able to terminate any services provided by giving 30 days written notice to Danaher. Once Newco has terminated any of the services, Newco shall not be permitted to request such services be resumed pursuant to the Transition Services Agreement.

Each party to the Transition Services Agreement generally agrees to indemnify the other party and other party’s related parties from claims related to the indemnifying party’s breach of its obligations under the Transition Services Agreement.

Trademark License Agreement

As of the Separation Date, pursuant to the Trademark License Agreement, Danaher will grant Newco a non-exclusive transitional license to use certain retained trademarks for applicable products bearing such marks as of the closing of the Separation and the Mergers and being transferred pursuant to the Distribution Agreement and Merger Agreement (including any modifications or updates thereto in the ordinary course of business), together with applicable materials related thereto. Each such license extends for 12 months following the closing of the Separation and the Mergers (or an additional 1-year extension period if requested by Newco and agreed by Danaher). The Trademark License Agreement will provide for applicable requirements regarding use and sublicensing of the licensed marks and will require the licensee to replace such marks with a new source indicator that is not similar thereto prior to the applicable termination date.

IP License Agreement

As of the Separation Date, pursuant to the Intellectual Property Cross-License Agreement (“IP License Agreement”), Danaher will grant Newco a perpetual and irrevocable, non-exclusive license to certain retained patents, copyrights and trade secrets owned by Danaher and used by Newco as of the closing of the Separation and the Mergers, or embodied by the technology delivered to Newco as of the closing, and Newco will grant Danaher a perpetual and irrevocable, non-exclusive license to certain patents, copyrights and trade secrets owned by Newco and used by Danaher as of the closing of the Separation and the Mergers. The IP License Agreement will provide for applicable requirements and restrictions regarding use and sublicensing of the licensed intellectual property.

DBS License Agreement

As of the Separation Date, pursuant to the DBS License Agreement, Danaher will grant a non-exclusive six-month license to Newco to use the Danaher Business System solely for internal business purposes relating solely to the Communications Business. Newco may sublicense such license solely to direct and indirect, wholly-owned subsidiaries (but only as long as such entities remain direct and indirect, wholly-owned subsidiaries).

Lease Agreement

In connection with the Distribution Agreement, Danaher or one of its subsidiaries (“Landlord”) and Newco or one of its subsidiaries (“Tenant”) will enter into the Commercial Lease Agreement (the “Lease”), to be executed at closing. Pursuant to the Lease, Landlord will lease to Tenant the land and improvements located at 3033 W President George Bush Highway, in Collin County, Plano, Texas (the “Premises”).

156

##### Table of Contents

The Lease is a triple net lease, such that Tenant is responsible for all taxes, insurance, utilities and costs and expenses relating to the repair, maintenance and operation of the Premises during the term of the Lease. The term of the Lease is approximately three years, subject to Tenant’s right to renew the term for one additional term of three years. In addition to paying all costs and expenses relating to the Premises as described above, Tenant is obligated to pay base rent during the first two lease years of $984,000 per annum and during the third lease year, of $3,000,000 per annum. The base rent during the renewal term lease years is based upon the increase in CPI over the prior period.

Tenant is permitted to use the Premises for general, executive and administrative office use and uses reasonably ancillary thereto. The Lease includes customary default provisions and remedies for Landlord in the case of such a default.

Tenant has the right to make alterations to the Premises, subject to Landlord’s consent (provided, however, no consent shall be required for non-structural cosmetic alterations if the price does not exceed agreed upon thresholds), not to be unreasonably withheld, conditioned or delayed, compliance with applicable legal requirements and providing security for the performance of the alteration if the cost thereof exceeds agreed upon thresholds.

Except for customary rights to terminate in the event of a casualty that is not repaired within agreed upon time periods or taking by eminent domain, Tenant does not have the right to an early termination of the Lease.

Landlord and Tenant generally have agreed to indemnify each other and each other’s related parties from claims related to the Premises and the use and occupancy thereof.

Subject to the terms of the Lease, Tenant has the right to purchase the Premises at or near the end of the term of the Lease (but not sooner than six months prior to the expiration of the term). Any such purchase is subject to customary escrow conditions but is not contingent upon Tenant obtaining financing or any other matter.

Voting Agreement

In connection with the Transactions, on October 12, 2014, Danaher and Anil Singhal (the “stockholder”) entered into a voting agreement. Pursuant to the Voting Agreement, the stockholder has agreed, subject to the termination of the Voting Agreement, at any meeting of the stockholders of NetScout, however called, or at any adjournment or postponement thereof, or on any written consent of the stockholders of NetScout, to vote or consent (or cause to be voted or consented) all of his 2,248,226 shares (“subject shares”) of NetScout common stock, representing approximately 5.5% of the total outstanding shares of NetScout common stock based on 41,181,526 shares of common stock reported outstanding as of October 10, 2014 (as represented by NetScout in the Merger Agreement): (a) in favor of the approval of the issuance of shares of NetScout common stock pursuant to the First Merger and any related proposals in furtherance thereof; and (b) against the following actions (other than the Mergers and the transactions contemplated by the Merger Agreement): (i) any acquisition proposal; (ii) any merger, tender offer, recapitalization, reorganization, consolidation, share exchange, business combination, liquidation, dissolution or similar transaction or series of transactions of NetScout or any of its subsidiaries; (iii) any amendment of NetScout’s certificate of incorporation; or (iv) any other action, proposal, transaction or agreement involving NetScout that would reasonably be expected to prevent or materially impede, interfere with, delay, postpone or adversely affect the transactions contemplated by the Merger Agreement, including the Mergers. In addition, the stockholder granted certain officers of Danaher a limited proxy to vote the subject shares in accordance with the foregoing voting commitment.

The stockholder has also agreed, among other things, subject to certain exceptions (including transfers to any person that agrees in writing to be bound by the terms of the Voting Agreement): not to (i) directly or indirectly, sell, transfer (except as may be specifically required by court order), pledge, encumber, hypothecate,

157

##### Table of Contents

assign or otherwise dispose of, by tendering into any tender or exchange offer, by operation of law or otherwise, either voluntarily or involuntarily, or enter into any contract, option or other arrangement or understanding with respect to the voting of or sale, transfer, pledge, encumbrance, hypothecation assignment or similar disposition of, the subject shares; (ii) grant any proxies or powers of attorney, or any other authorization or consent with respect to any or all of the subject shares that could reasonably be expected to prevent, nullify, impede, interfere with, frustrate, delay, postpone, discourage or otherwise materially adversely affect the Mergers, the Merger Agreement, any of the transactions contemplated by the Merger Agreement or the Voting Agreement; or (iii) deposit any of the subject shares into a voting trust or enter into a voting agreement with respect to any of the subject shares.

The voting agreement also provides that nothing in the Voting Agreement limits the discretion of the stockholder to take or not take any action in his fiduciary capacity as director of NetScout. Also, the obligations of the stockholder shall not be affected by any Change in Recommendation.

Each of the parties to the Voting Agreement has made customary representations and warranties, including with respect to authority to enter into and carry out its obligation under, and enforceability of, the Voting Agreement.

The stockholder is also subject to the non-solicitation covenants applicable to NetScout and its representatives in the Merger Agreement.

The voting agreement and the limited proxy granted thereunder will automatically terminate upon the earliest of (i) the effective time of the First Merger and (ii) the termination of the Merger Agreement.

DESCRIPTION OF NETSCOUT CAPITAL STOCK

The rights of NetScout stockholders are governed by the DGCL, the NetScout Charter and the NetScout Bylaws. For information on how to obtain a copy of the NetScout Charter and the NetScout Bylaws, see “Where You Can Find More Information; Incorporation by Reference.”

The following description of NetScout’s capital stock does not purport to be complete and is subject to, and qualified in its entirety by reference to, the complete text of the NetScout Charter and the NetScout Bylaws.

Common Stock

The NetScout Charter authorizes the issuance of up to 150 million shares of common stock, par value $0.001 per share. As of November 24, 2014, there were 41,217,480 shares of NetScout common stock issued and outstanding.

There is one class of authorized NetScout common stock which is entitled to one vote per share of common stock held of record on the applicable record date on all matters submitted to a vote of stockholders. There are no cumulative voting rights. Except as otherwise required by law or the NetScout Charter, each holder of NetScout common stock shall have one vote in respect of each share of NetScout common stock held of record by such holder. The holders of NetScout common stock are entitled to receive, from funds legally available for the payment thereof, dividends when and as declared by resolution of the NetScout board of directors, subject to any preferential dividend rights granted to the holders of any then outstanding preferred stock. In the event of liquidation, each share of NetScout common stock is entitled to share pro rata in any distribution of NetScout’s assets after payment or providing for the payment of liabilities and the liquidation preference of any then outstanding preferred stock. Holders of NetScout common stock have no preemptive rights to purchase, subscribe for or otherwise acquire any unissued or treasury shares or other securities.

Preferred Stock

The NetScout Charter authorizes the NetScout board of directors, without stockholder approval, to create one or more classes or series within a class of preferred stock, to issue shares of preferred stock in such class or series up to the maximum number of shares of the relevant class or series of preferred stock authorized, and to determine the preferences, rights, privileges, qualifications, limitations, and restrictions of any such class or series, including the dividend rights, dividend rates, voting rights, the rights and terms of redemption, redemption prices, the rights and terms of conversion, liquidation preferences, sinking fund terms, the number of shares constituting any such class or series, and the designation of such class or series. Currently, the NetScout board of directors can designate up to 5 million shares of preferred stock.

The NetScout board of directors shall determine the rights, preferences, privileges and restrictions of the 5,000,000 undesignated shares of preferred stock, including dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences, sinking fund terms and the number of shares constituting any series or the designation of any series.

If NetScout decides to sell shares of preferred stock, the NetScout board of directors will fix the rights, preferences, privileges and restrictions of the preferred stock of each series in the certificate of designation relating to that series.

Certain Anti-Takeover Effects of Provisions of the NetScout Charter and the NetScout Bylaws

NetScout is subject to Section 203 of the DGCL. Subject to certain exceptions, Section 203 prevents a publicly held Delaware corporation from engaging in a “business combination” with any “interested stockholder” for three years following the date that the person became an interested stockholder, unless the interested

159

##### Table of Contents

stockholder attained such status with the approval of the NetScout board of directors or unless the business combination is approved in a prescribed manner. A “business combination” includes, among other things, a merger or consolidation involving us, and the interested stockholder and the sale of more than 10% of NetScout’s assets. In general, an “interested stockholder” is any entity or person beneficially owning 15% or more of NetScout’s outstanding voting stock and any entity or person affiliated with or controlling or controlled by such entity or person.

The NetScout Charter provides that the directors elected may be removed with cause only by the holders of at least a majority of the shares then entitled to vote at an election of directors or without cause only by the holders of at least a 75% of the shares then entitled to vote at an election of directors. Under the NetScout Bylaws, unless and until filled by the stockholders, any vacancy or newly created directorships on the NetScout board of directors may be filled by vote of a majority of the directors then in office, although less than a quorum, or by a sole remaining director.

The NetScout Charter and the NetScout Bylaws provide that any action required or permitted to be taken by NetScout stockholders at an annual meeting or special meeting of stockholders may only be taken if it is properly brought before such meeting. The NetScout Bylaws also provide that, except as otherwise required by law, special meetings of the stockholders can only be called by NetScout’s Chairman, president or by a majority vote of the NetScout board of directors. In addition, the NetScout Bylaws establish an advance notice procedure for stockholder proposals to be brought before an annual meeting of stockholders, including proposed nominations of candidates for election to the NetScout board of directors. Stockholders at an annual meeting may only consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of the NetScout board of directors or by a stockholder of record on the record date for the meeting, who is entitled to vote at the meeting and who has delivered timely written notice in proper form to the NetScout secretary of the stockholder’s intention to bring such business before the meeting. These provisions could have the effect of delaying stockholder actions that are favored by the holders of a majority of NetScout’s outstanding voting securities until the next stockholder meeting.

The DGCL provides generally that the affirmative vote of a majority of the shares entitled to vote on any matter is required to amend a corporation’s certificate of incorporation or bylaws, unless a corporation’s certificate of incorporation or bylaws, as the case may be, requires a greater percentage. Portions of the NetScout Charter may be amended by the affirmative vote of the holders of at least 75% of the votes which all the NetScout stockholders would be entitled to vote. The NetScout Bylaws may be amended or repealed by a majority vote of the NetScout board of directors or by the affirmative vote of the holders of at least 75% of the votes which all NetScout stockholders would be entitled to cast in any annual election of directors.

PROPOSAL NO. 1—

PROPOSAL TO APPROVE THE ISSUANCE OF SHARES OF NETSCOUT COMMON STOCK

IN THE FIRST MERGER

For a summary and detailed information regarding this proposal, see the information about the proposed Mergers, and the issuance of shares of NetScout common stock in the First Merger, contained throughout this document, including the information set forth in the sections of this document entitled “The Transactions,” “The Merger Agreement” and the “Distribution Agreement.”

Copies of the Merger Agreement and the Distribution Agreement are attached to this document as Annex A and Annex B, respectively.

If the proposal to approve the issuance of shares of NetScout common stock in the First Merger is not approved, the Mergers cannot be completed, and each of Danaher and NetScout will have the right to terminate the Merger Agreement, as described in the section entitled “The Merger Agreement—Termination.”

Required Vote

This proposal regarding the issuance of shares of NetScout common stock in the First Merger must be approved by the affirmative vote of a majority of the shares of NetScout common stock represented and voting at the special meeting, either in person or by proxy (assuming a quorum is present). Abstentions would have the same effect as a vote against this proposal and broker non-votes would have no effect on the outcome of the vote on this proposal.

NetScout’s board of directors recommends that stockholders vote “FOR” the proposal to issue shares of NetScout common stock in the First Merger.

PROPOSAL NO. 2—

PROPOSAL TO APPROVE THE ADJOURNMENT OR POSTPONEMENT OF THE

SPECIAL MEETING, IF NECESSARY OR APPROPRIATE

If, at the special meeting of stockholders, the board of directors of NetScout determines it is necessary or appropriate to adjourn or postpone the special meeting in order to solicit additional proxies if there are not sufficient votes at the time of the special meeting to approve the proposal to issue shares of NetScout common stock in the First Merger, NetScout intends to move to adjourn or postpone the special meeting. If the board of directors of NetScout determines that adjournment or postponement of the special meeting is necessary or appropriate, NetScout will ask its stockholders to vote only upon the adjournment or postponement proposal, and not on the proposal to approve the issuance of shares of NetScout common stock in the Merger.

In this proposal, NetScout is asking NetScout Stockholders to vote in favor of adjournment or postponement of the special meeting to a later date or time, if necessary or appropriate, to solicit additional proxies if there are not sufficient votes at the time of the special meeting to approve the issuance of shares of NetScout common stock in the First Merger. If the stockholders approve the adjournment or postponement proposal, NetScout could adjourn or postpone the special meeting and use the additional time to solicit additional proxies, including the solicitation of proxies from stockholders that have previously voted. Among other things, approval of the adjournment or postponement proposal could mean that, even if NetScout had received proxies representing a sufficient number of votes against the issuance of NetScout common stock in the First Merger to defeat that proposal, NetScout could adjourn or postpone the special meeting without a vote and seek to convince the holders of those shares to change their votes to vote in favor of approval of the issuance of shares of NetScout common stock in the First Merger.

Required Vote

This proposal regarding the adjournment or postponement of the special meeting, if necessary or appropriate, to solicit additional proxies if there are not sufficient votes at the time of the special meeting to approve the issuance of shares of NetScout common stock in the First Merger must be approved by the affirmative vote of a majority of the shares of NetScout common stock represented and voting at the special meeting, either in person or by proxy. Abstentions would have the same effect as a vote against this proposal and broker non-votes would have no effect on the outcome of the vote on this proposal if it is submitted for approval when no quorum is present at the special meeting.

NetScout’s board of directors recommends that stockholders vote “FOR” the proposal to approve adjournments or postponements of the special meeting for the purpose of soliciting additional proxies, if necessary or appropriate.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Danaher Corporation

We have audited the accompanying combined balance sheets of the Communications Business of Danaher Corporation (the Company), a wholly-owned business of Danaher Corporation, as of December 31, 2013 and 2012, and the related combined statements of earnings, comprehensive income, changes in parent’s equity and cash flows for each of the three years in the period ended December 31, 2013. Our audits also included the financial statement schedule listed at Item 21(b). These financial statements and schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Company’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing 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 over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the combined financial statements referred to above present fairly, in all material respects, the combined financial position of the Communications Business of Danaher Corporation at December 31, 2013 and 2012, and the combined results of its operations and its cash flows for each of the three years in the period ended December 31, 2013 in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

COMMUNICATIONS BUSINESS OF DANAHER CORPORATION

NOTES TO COMBINED FINANCIAL STATEMENTS

(1) BUSINESS OVERVIEW AND BASIS OF PRESENTATION

The accompanying combined financial statements present the historical financial position, results of operations, changes in Parent’s equity and cash flows of the Communications Business of Danaher Corporation (the “Business”) in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for the preparation of carved-out combined financial statements.

The Business consists of certain operating units of Danaher Corporation (“Danaher”) and is a premier global provider of network management tools and security solutions for telecommunications carriers and network enterprise customers. The Business’ products enable organizations to gain unique and encompassing real-time analytical insights to better design, deploy, monitor and secure the traditional, virtualized, mobile and cloud-based networks operated by communication service providers, hosters, enterprises and government agencies worldwide. The Business’ products simplify the complexity of understanding and effectively managing the underlying network technologies, communication services and subscriber interactions.

On October 13, 2014, Danaher announced a definitive agreement with NetScout Systems, Inc. (“NetScout”) to combine the Business with NetScout (the “Transaction”). The Transaction will be structured as a distribution of the Business to Danaher shareholders in either a spin-off transaction, a split-off transaction, or a combination split-off and spin-off, followed by a merger with a subsidiary of NetScout for consideration of 62.5 million NetScout shares, subject to adjustment. Both the distribution and merger are expected to qualify as tax-free transactions to Danaher and its shareholders, except to the extent that cash is paid to Danaher stockholders in lieu of fractional shares. If Danaher elects a spin-off, all Danaher shareholders will participate pro-rata. If Danaher elects a split-off, Danaher will conduct an exchange offer pursuant to which its shareholders will elect whether to exchange Danaher shares for common units of the Business. If the split-off exchange offer is not fully subscribed, the additional Business common units held by Danaher will be distributed in a spin-off on a pro rata basis to Danaher shareholders. Danaher will determine which approach it will take prior to closing the transaction and no decision has been made at this time. The transaction remains subject to approval by NetScout’s shareholders and the satisfaction of customary closing conditions, including regulatory approvals and the absence of a material adverse change with respect to each of the Business and NetScout. At closing, depending on the number of shares of NetScout common stock outstanding, Danaher shareholders will receive approximately 59.5% of the shares of NetScout stock outstanding following the combination. The Transaction is expected to be completed in 2015.

The Business has historically operated as part of Danaher and not as a stand-alone company and has no separate legal status or existence. The financial statements have been derived from Danaher’s historical accounting records and are presented on a carve-out basis. All revenues and costs as well as assets and liabilities directly associated with the business activity of the Business are included as a component of the financial statements. The financial statements also include allocations of certain general, administrative, sales and marketing expenses and cost of sales from Danaher’s corporate office and from other Danaher businesses to the Business and allocations of related assets, liabilities, and Parent’s investment, as applicable. The allocations have been determined on a reasonable basis; however, the amounts are not necessarily representative of the amounts that would have been reflected in the financial statements had the Business been an entity that operated independently of Danaher. Related party allocations are discussed further in Note 16.

As part of Danaher, the Business is dependent upon Danaher for all of its working capital and financing requirements as Danaher uses a centralized approach to cash management and financing of its operations. Financial transactions relating to the Business are accounted for through the Parent investment account of the Business. Accordingly, none of Danaher’s cash, cash equivalents or debt at the corporate level has been assigned to the Business in the financial statements.

F-8

##### Table of Contents

Net parent investment, which includes retained earnings, represents Danaher’s interest in the recorded net assets of the Business. All significant transactions between the Business and Danaher have been included in the accompanying combined financial statements. Transactions with Danaher are reflected in the accompanying Combined Statements of Changes in Parent’s Equity as “Net transfers from (to) parent” and in the accompanying Combined Balance Sheets within “Net parent investment”.

All significant intercompany accounts and transactions between the operations comprising the Business have been eliminated in the accompanying financial statements.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates—The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. The Business bases these estimates on historical experience, the current economic environment and on various other assumptions that are believed to be reasonable under the circumstances. However, uncertainties associated with these estimates exist and actual results may differ from these estimates.

Accounts Receivable and Allowances for Doubtful Accounts—The Business records accounts receivable at their face amount less an allowance for doubtful accounts. An allowance for doubtful accounts is maintained at an amount estimated to be sufficient to cover the risk of collecting less than full payment on receivables. On a regular basis, the Business re-evaluates customer receivables and reassesses the sufficiency of the allowance for doubtful accounts based on specific customer collection issues.

All accounts receivable are reported on the accompanying Combined Balance Sheets adjusted for any write-offs and net of allowances for doubtful accounts. The allowances for doubtful accounts represent management’s best estimate of the credit losses expected from the Business’ trade accounts. Determination of the allowances requires management to exercise judgment about the timing, frequency and severity of credit losses that could materially affect the allowance for doubtful accounts and, therefore, net earnings. The Business regularly performs detailed reviews of its portfolios to determine if an impairment has occurred and evaluates the collectability of receivables based on a combination of financial and qualitative factors that may affect customers’ ability to pay, including customers’ financial condition, past payment experience and credit bureau information. In circumstances where the Business is aware of a specific customer’s inability to meet its financial obligations, a specific reserve is recorded against amounts due to reduce the recognized receivable to the amount reasonably expected to be collected. Additions to the allowances for doubtful accounts are charged to current period earnings, amounts determined to be uncollectible are charged directly against the allowances, while amounts recovered on previously written-off accounts increase the allowances. If the financial condition of the Business’ customers were to deteriorate, resulting in an impairment of their ability to make payments, additional reserves would be required. The Business recorded a provision of $710,000, $467,000, and $1,891,000 associated with doubtful accounts for the years ended December 31, 2013, 2012, and 2011 respectively.

Sales to the Business’ largest two customers were 36% of total sales in 2013, 33% in 2012, and 33% in 2011. No other individual customer accounted for more than 10% of combined sales in 2013, 2012, or 2011. Accounts receivable from these customers was 11% of total receivables at December 31, 2013 and 9% at December 31, 2012.

Inventory Valuation—Inventories include the costs of material, labor and overhead. Inventories are stated at the lower of cost or market using the first-in, first-out (“FIFO”) method to value inventory.

##### Table of Contents

Property, Plant and Equipment—Property, plant and equipment are carried at cost. The provision for depreciation has been computed principally by the straight-line method based on the estimated useful lives of the depreciable assets as follows:

Category |  | Useful Life
Buildings |  | 30 years
Leased assets and leasehold improvements |  | Amortized over the lesser of the economic life of the asset or the term of the lease
Machinery and equipment |  | 3 – 10 years

Estimated useful lives are periodically reviewed and, when appropriate, changes to estimates are made prospectively.

Other Assets—Other assets principally include non-current deferred tax assets.

Goodwill and Other Intangible Assets—Goodwill and other intangible assets result from the Business’ acquisition of existing businesses. In accordance with accounting standards related to business combinations, goodwill is not amortized, however, certain definite-lived identifiable intangible assets, primarily customer relationships and acquired technology, are amortized over their estimated useful lives. Intangible assets with indefinite lives are not amortized. In-process research and development (“IPR&D”) is initially capitalized at fair value and when the IPR&D project is complete, the asset is considered a finite-lived intangible asset and amortized over its estimated useful life. If an IPR&D project is abandoned, an impairment loss equal to the value of the intangible asset is recorded in the period of abandonment. The Business reviews identified intangible assets for impairment whenever events or changes in circumstances indicate that the related carrying amounts may not be recoverable.

The Business also tests intangible assets with indefinite lives at least annually for impairment. Refer to Note 6 for additional information about the Business’ goodwill and other intangible assets.

Revenue Recognition—The Business derives revenues primarily from the sale of network management tools and security solutions for carrier and enterprise customers, which include hardware, software and service offerings. The majority of the Business’ product sales consist of a hardware product with embedded software that is essential to providing the customer the intended functionality of the solution. In addition, the Business sells stand-alone software and software-as-a-service solutions to provide customers with enhanced functionality. The Business’ service offerings include installation, integration, extended warranty and maintenance services, post-contract customer support (“PCS”), and other professional services.

For revenue related to a product or service to qualify for recognition, there must be persuasive evidence of an arrangement, delivery must have occurred or the services must have been rendered, the price to the customer must be fixed and determinable and collectability of the balance must be reasonably assured, or probable in the case of stand-alone software sales. The Business evaluates delivery for product sales based on shipping terms and when title and risk of loss have passed to the customer, and in the case of software products, when the customer has the rights and ability to access the software. The Business generally considers services to be delivered as performed or upon completion to the extent there are significant customer acceptance obligations. If any significant obligations to the customer remain to be fulfilled following delivery, typically involving obligations relating to installation and acceptance by the customer, revenue recognition is deferred until such obligations have been fulfilled.

Management is required to exercise judgment and use estimates in connection with evaluating these criteria and determining the amounts of product and service revenues to be recognized.

F-10

##### Table of Contents

Certain of the Business’ contractual arrangements consist of multiple elements (i.e., deliverables) which may include hardware, software, PCS and other services. Revenues for contractual arrangements consisting of multiple elements are recognized for the separate elements when the product or services that are part of the multiple-element arrangement have value on a stand-alone basis, fair value of the separate elements exists and, in arrangements that include a general right of refund relative to the delivered element, performance of the undelivered element is considered probable and substantially in the Business’ control. Allocation of the consideration is determined at the arrangement’s inception.

When a multiple-element arrangement includes software and non-software elements, the arrangement fee is first allocated between the software and non-software elements based on the relative selling prices of all deliverables and then allocated to the individual deliverables in the arrangement. Software elements in a multiple element arrangement are recognized based on their relative vendor-specific objective evidence (“VSOE”) of fair value. If VSOE does not exist for all software elements, revenue is deferred until either: i) VSOE does exist for all elements, ii) all elements have been delivered, or iii) VSOE for all undelivered elements is known and the residual method is used to recognize revenue of delivered elements. Non-software elements in a multiple-element arrangement are recognized based on their relative selling prices determined by the selling price hierarchy. The selling price for a non-software deliverable is based on VSOE, if available, third party evidence (“TPE”) if VSOE is not available, or estimated selling price (“ESP”) if neither VSOE or TPE is available. The Business considers relevant internal and external market factors in cases where the Business is required to estimate selling prices.

Product returns consist of estimated returns for products sold and are recorded as a reduction in reported revenues at the time of sale. Customer allowances and rebates, consisting primarily of volume discounts and other short-term incentive programs, are recorded as a reduction in reported revenues at the time of sale because these allowances reflect a reduction in the purchase price. Product returns, customer allowances and rebates are estimated based on historical experience and known trends.

Deferred Revenue—Deferred revenue includes amounts which have been billed in accordance with contractual terms but have not yet been recognized as revenue because the criteria for revenue recognition have not been met.

Shipping and Handling—Shipping and handling costs are included as a component of cost of sales. Shipping and handling costs billed to customers are included in sales.

Research and Development—The Business conducts research and development activities for the purpose of developing new products, enhancing the functionality, effectiveness, ease of use and reliability of the Business’ existing products and expanding the applications for which uses of the Business’ products are appropriate. Research and development costs are expensed as incurred.

Income Taxes—The Business’ domestic and foreign operating results are included in the income tax returns of Danaher. The Business accounts for income taxes under the separate return method. Under this approach, the Business determines its deferred tax assets and liabilities and related tax expense as if it were filing a separate tax return. The accompanying Combined Balance Sheet does not contain a current taxes payable liability as it is deemed settled with Danaher when due and therefore included in Parent’s Equity. Deferred tax liabilities and assets are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted rates expected to be in effect during the year in which the differences reverse. Deferred tax assets generally represent items that could be used as tax deductions or credits in the future for which the tax benefit has already been reflected on the Business’ Combined Statements of Earnings. The Business establishes valuation allowances for its deferred tax assets if it is more likely than not that some or all of the deferred tax assets would not be realized on a separate return basis. Deferred tax liabilities generally represent items that would have already been taken as deductions on the Business’ separate tax return but have not yet been recognized as an expense in the Business’ Combined Statements of Earnings. The effect on deferred tax assets and liabilities due to a change in tax rates is recognized as income tax expense in the period that includes the enactment date. A tax benefit or expense is recognized for the net change in the deferred tax asset or liability

during the year and the current tax liability for the year. The Business accounts for uncertain tax positions by recognizing the financial statement effects of a tax position only when, based upon the technical merits, it is “more-likely-than-not” that the position will be sustained upon examination. Judgment is required in evaluating tax positions and determining income tax provisions. The Business re-evaluates the technical merits of its tax positions and may recognize an uncertain tax benefit in certain circumstances, including when: (i) a tax audit is completed; (ii) applicable tax laws change, including a tax case ruling or legislative guidance; or (iii) the applicable statute of limitations expires. The Business recognizes accrued interest and penalties associated with unrecognized tax positions within income tax expense. Refer to Note 12 for additional information.

Restructuring—The Business periodically initiates restructuring activities to appropriately position the Business’ cost base relative to prevailing economic conditions and associated customer demand. Costs associated with restructuring actions can include one-time termination benefits and related charges in addition to facility closure, contract termination and other related activities. The Business records the cost of the restructuring activities when the associated liability is incurred. Refer to Note 14 for additional information.

Foreign Currency Translation—Exchange rate adjustments resulting from foreign currency transactions are recognized in net earnings, whereas adjustments resulting from the translation of financial statements are reflected as a component of accumulated other comprehensive income (loss) within parent’s equity. Net foreign currency transaction gains or losses were not material in any of the years presented.

Accounting for Stock Options—Certain employees of the Business participate in Danaher’s share-based compensation plans which include stock options and restricted stock units (“RSUs”). The Business accounts for stock-based compensation incurred by Danaher by measuring the fair value of the award as of the grant date. Equity-based compensation expense is recognized net of an estimated forfeiture rate on a straight-line basis over the requisite service period of the award, except that in the case of RSUs, compensation expense is recognized using an accelerated attribution method.

Pension Plans—The Business measures its pension assets and its obligations that determine the respective plan’s funded status as of the end of the Business’ fiscal year, and recognizes an asset for a plan’s overfunded status or a liability for a plan’s underfunded status in its balance sheet. Changes in the funded status of the plans are recognized in the year in which the changes occur and reported in comprehensive income (loss).

Recently Issued Accounting Pronouncements—In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606), which impacts virtually all aspects of an entity’s revenue recognition. The core principle of the new standard is that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard is effective for annual reporting periods beginning after December 15, 2016. Management has not yet completed its assessment of the impact of the new standard, including possible transition alternatives, on the Business’ financial statements.

Accumulated Other Comprehensive Income (Loss)—Effective January 1, 2013, the Business adopted accounting guidance that requires the Business to separately disclose, on a prospective basis, the change in each component of other comprehensive income (loss) relating to reclassification adjustments and current period other comprehensive income (loss). As the guidance relates to presentation only, the adoption did not have a material impact on the Business’ results of operations, financial position or cash flows.

Foreign currency translation adjustments are generally not adjusted for income taxes as they relate to the Business’ indefinite investments in non-U.S. subsidiaries.

Subsequent Events—The Business has evaluated subsequent events for recording or disclosure in these financial statements. There were no such events other than the Transaction described in Note 1.

(3) ACQUISITIONS

As part of Danaher, the Business continually evaluates potential acquisitions that either strategically fit with the Business’ existing portfolio or expand the Business’ portfolio into a new and attractive business area. The Business has completed several acquisitions that have been accounted for as purchases and have resulted in the recognition of goodwill in the Business’ financial statements. This goodwill arises because the purchase prices for these businesses reflect a number of factors including the future earnings and cash flow potential of these businesses, the multiple to earnings, cash flow and other factors at which similar businesses have been purchased by other acquirers, the competitive nature of the processes by which the Business acquired the businesses and the complementary strategic fit and resulting synergies these businesses bring to existing operations.

F-13

##### Table of Contents

The Business makes an initial allocation of the purchase price at the date of acquisition based upon its understanding of the fair value of the acquired assets and assumed liabilities. The Business obtains this information during due diligence and through other sources. In the months after closing, as the Business obtains additional information about these assets and liabilities, including through tangible and intangible asset appraisals, and learns more about the newly acquired business, it is able to refine the estimates of fair value and more accurately allocate the purchase price. Only items identified as of the acquisition date are considered for subsequent adjustment. The Business evaluates whether any adjustments to the purchase accounting are material and assesses if any retrospective adjustments to prior period financial statements are required. The accompanying financial statements reflect the impact of all adjustments to the initial purchase accounting as of the original acquisition dates.

In connection with acquisitions, the Business may enter into post-closing financial arrangements such as purchase price adjustments, earn-out obligations and indemnification obligations. These obligations are recorded at their fair value at the time of acquisition and require management to make judgments and estimates about the ultimate settlement amount. While the Business believes it has made reasonable estimates and assumptions to calculate the fair value of these obligations, if actual results are not consistent with management’s estimates and assumptions, these obligations may be understated and a charge would need to be taken against net earnings. As of December 31, 2013, the Business had recorded an estimated earn-out liability for arrangements in connection with acquisitions of $24,896,000. The maximum exposure for these earn-out obligations as of December 31, 2013 is estimated at $33,067,000 and these earn-out obligations are expected to be resolved by 2015.

The acquisitions made during 2013 and 2012 enhanced the technology platforms and research and development capabilities of the Business. The following briefly describes the Business’ acquisition activity for the years ended December 31, 2013 and 2012. There were no acquisitions in 2011.

During 2013, the Business acquired two businesses for total consideration of $74,719,000 in cash, net of cash acquired. The aggregate annual sales of these two businesses at the time of their respective acquisitions, in each case based on the business’ revenues for its last completed fiscal year prior to the acquisition, were approximately $13,100,000. Due to the timing of these acquisitions during 2013, they did not materially impact the Business’ sales or operating profit during 2013. The Business recorded an aggregate of $62,621,000 of goodwill related to these acquisitions.

During 2012, the Business acquired VSS Monitoring, Inc (“VSS”) for total consideration of $189,138,000 in cash, net of cash acquired. The aggregate annual sales of this business at the time of its acquisition, based on VSS’ revenues for its last completed fiscal year prior to the acquisition, were $31,346,000. In addition in 2012, VSS contributed $30,163,000 to sales and reported a loss before income taxes of $8,552,000 from the date of acquisition. The Business recorded an aggregate of $135,927,000 of goodwill related to this acquisition.

The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the date of acquisition for all acquisitions consummated during 2013 and 2012 ($ in thousands):

Transaction related costs were not material to 2013, 2012 or 2011 earnings. The Business’ earnings for the year ended December 31, 2012 reflects the impact of additional pre-tax charges totaling $3,026,000 associated with fair value adjustments to inventory and deferred revenue related to the acquired business. These amounts were not material for the year ended December 31, 2013.

(6) GOODWILL & OTHER INTANGIBLE ASSETS

As discussed in Note 2, goodwill arises from the purchase price for acquired businesses exceeding the fair value of tangible and intangible assets acquired less assumed liabilities and non-controlling interests. The Business assesses goodwill for impairment at least annually in the fourth quarter of each year, or more frequently as “triggering” events occur that indicate that it is more likely than not than an impairment exists. In performing its

F-15

##### Table of Contents

goodwill impairment test, the business first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. Qualitative factors that the Business considers include macroeconomic conditions, industry and market considerations, cost factors, and overall financial performance. If qualitative factors indicate that an impairment may have occurred, the Business performs a quantitative impairment test. The Business may opt to bypass the qualitative test in any given period.

As of December 31, 2013, the Business had four reporting units for goodwill impairment testing. The carrying value of the goodwill included in each individual reporting unit ranges from $59,330,000 to $422,475,000. In 2011 and 2012, the qualitative impairment test indicated that an impairment of goodwill was not more likely than not. In 2013, the Business opted to skip the qualitative test and performed the quantitative impairment test for all reporting units. In performing its quantitative assessment of goodwill impairment, management relied on a number of factors including operating results, business plans, economic projections, anticipated future cash flows, and transactions and marketplace data. These factors are inherently subject to uncertainty and require management to make estimates and exercise judgment. While the Business believes it has made reasonable estimates and assumptions to calculate the fair value of its reporting units, if actual results are not consistent with management’s estimates and assumptions, goodwill and other intangible assets may be overstated and a charge would need to be taken against net earnings. No goodwill impairment charges were recorded for the years ended December 31, 2013, 2012 and 2011 and no “triggering” events have occurred subsequent to the performance of the latest annual impairment test.

The following table shows the rollforward of goodwill reflected in the financial statements resulting from the Business’ activities during 2013 and 2012 ($ in thousands):

|  | Total |
Balance, January 1, 2012 |  | $ | 511,947 |

During 2013 and 2012, the Company acquired finite-lived intangible assets, consisting primarily of patents and technology and customer relationships with a weighted average life of 7 and 10 years, respectively. Refer to Note 3 for additional information about acquired intangible assets.

F-16

##### Table of Contents

Total intangible amortization expense in 2013, 2012 and 2011 was $29,005,000, $25,612,000 and $23,777,000, respectively of which $9,344,000, $8,285,000 and $8,153,000 are included in costs of sales for the years ended December 31, 2013, 2012 and 2011, respectively. Based on the finite-lived intangible assets recorded as of December 31, 2013, amortization expense is estimated to be $25,944,000 during 2014, $25,240,000 during 2015, $21,692,000 during 2016, $19,428,000 during 2017 and $19,428,000 during 2018.

The Business reviews identified intangible assets for impairment whenever events or changes in circumstances indicate that the related carrying amounts may not be recoverable. The Business also tests intangible assets with indefinite lives at least annually for impairment. Determining whether an impairment loss occurred requires a comparison of the carrying amount to the sum of undiscounted cash flows expected to be generated by the asset. These analyses require management to make judgments and estimates about future revenues, expenses, market conditions and discount rates related to these assets.

As a result of these impairment analyses, the Business recorded impairment charges of $31,063,000 in 2013 and $4,947,000 in 2011 related to the value of customer relationship and technology intangible assets. There were no impairments recorded in 2012. The 2013 impairment charge was recorded to reduce the value of certain customer relationship assets to their estimated fair value. These customer relationship assets were deemed to be impaired because as of December 31, 2013, orders and financial results of the acquired business to which these assets relate had not materialized according to the original expectations of the Business as of the date of acquisition. The 2011 impairment charge was recorded to reduce the value of certain customer relationship and technology assets to their estimated fair value. These intangible assets were deemed to be impaired because as of December 31, 2011, financial results of the acquired business to which these assets relate had lagged behind the original expectations of the Business as of the date of acquisition.

(7) FAIR VALUE MEASUREMENTS

Accounting standards define fair value based on an exit price model, establish a framework for measuring fair value where the Business assets and liabilities are required to be carried at fair value and provide for certain disclosures related to the valuation methods used within a valuation hierarchy as established within the accounting standards. This hierarchy prioritizes the inputs into three broad levels as follows. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets in markets that are not active, or other observable characteristics for the asset or liability, including interest rates, yield curves and credit risks, or inputs that are derived principally from, or corroborated by, observable market data through correlation. Level 3 inputs are unobservable inputs based on the Business’ assumptions. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement in its entirety.

A summary of financial assets and liabilities that are measured at fair value on a recurring basis as of December 31, 2013 and 2012 were as follows ($ in thousands):

There have been no transfers of assets or liabilities between the fair value measurement levels. The earn-out obligations recorded in 2013 are related to acquisitions made in that year and represent the Business’ estimate of the fair value of the liability based on the expected results of operations and achievement of other significant operational milestones of the acquired businesses during the earn-out period. As of December 31, 2012 the Business had not recorded any earn-out obligations. See Note 3 for more information on earn-out obligations.

(9) PENSION BENEFIT PLANS

Certain of the Business’ non-U.S. employees participate in certain of Danaher’s noncontributory defined benefit pension plans. None of the Business’ employees in the U.S. participate in any Danaher noncontributory defined benefit pension plans. In general, these plans are funded based on considerations relating to legal requirements, underlying asset returns, the plans’ funded status, the anticipated deductibility of the contribution, local practices, market conditions, interest rates and other factors. The following sets forth the funded status of the plans as of the most recent actuarial valuations using measurement dates of December 31, 2013 and 2012 ($ in thousands):

The discount rate reflects the market rate on December 31 for high-quality fixed-income investments with maturities corresponding to the Business’ benefit obligations and is subject to change each year. Rates appropriate for each plan are determined based on investment grade instruments with maturities approximately equal to the average expected benefit payout under the plan.

As of December 31, 2013, unrecognized actuarial losses of $1,873,000 ($1,315,000, net of tax) which have not yet been recognized in net periodic pension cost are included in accumulated other comprehensive income. The unrecognized actuarial losses are calculated as the difference between the actuarially determined projected benefit obligation and the value of the plan assets less accrued pension costs as of December 31, 2013. None of this amount is expected to be recognized in net periodic pension costs during the year ending December 31, 2014. No plan assets are expected to be returned to the Business during the year ending December 31, 2014.

Selection of Expected Rate of Return on Assets

Long-term rate of return on asset assumptions were determined on a plan-by-plan basis based on the composition of assets and ranged from 4% to 6% and in each of 2013 and 2012, with a weighted average rate of return assumption of 5% in each of 2013 and 2012.

Plan Assets

Plan assets are invested in various insurance contracts, equity and debt securities as determined by the administrator of each plan. The value of the plan assets directly affects the funded status of the Business’ pension plans recorded in the financial statements. Plan assets are held in a collective trust for the overall Danaher plans. They have been allocated to the Business in proportion to the Business’ proportion of the overall obligation in each year. The fair values of the Business’ pension plan assets as of December 31, 2013, by asset category were as follows ($ in thousands):

Preferred stock and certain common stock and mutual funds are valued at the quoted closing price reported on the active market on which the individual securities are traded. Common stock, corporate bonds, U.S. government securities and mutual funds that are not traded on an active market are valued at quoted prices reported by investment brokers and dealers based on the underlying terms of the security and comparison to similar securities traded on an active market.

Venture capital, partnerships and other private investments are valued based on the information provided by the asset fund managers, which reflects the plan’s share of the fair value of the net assets of the investment. The

F-20

##### Table of Contents

investments are valued using a combination of either discounted cash flows, earnings and market multiples, third party appraisals or through reference to the quoted market prices of the underlying investments held by the venture, partnership or private entity where available. Valuation adjustments reflect changes in operating results, financial condition, or prospects of the applicable portfolio company.

The methods described above may produce a fair value estimate that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Business believes the valuation methods are appropriate and consistent with the methods used by other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

The table below sets forth a summary of changes in the fair value of the Business’ Level 3 venture capital, partnerships, other private investments and real estate for the years ended December 31, 2013 and 2012 ($ in thousands):

Expected Contributions

During 2013, the Business did not make any contributions to its defined benefit pension plans. During 2014, the Business cash contribution requirements for its defined benefit pension plans are expected to be approximately $93,000.

As the participants within the Business’ plans are all active employees, the benefit payments are not expected to be material in the foreseeable future.

Other Matters

Substantially all employees not covered by defined benefit plans are covered by defined contribution plans, which generally provide for Business funding based on a percentage of compensation. Expense for all defined benefit and defined contribution pension plans amounted to $8,418,000, $7,163,000, and $6,315,000 for the years ended December 31, 2013, 2012 and 2011, respectively.

(10) LEASES AND COMMITMENTS

The Business’ operating leases extend for varying periods of time up to nine years. Future minimum rental payments for all operating leases having initial or remaining non-cancelable lease terms in excess of one year are $6,696,000 in 2014, $6,600,000 in 2015, $6,367,000 in 2016, $5,073,000 in 2017, $2,419,000 in 2018 and $2,303,000 thereafter. Rent expense related to operating leases was $6,025,000, $5,204,000, and $4,258,000 for the years ended December 31, 2013, 2012 and 2011, respectively.

##### Table of Contents

The Business generally accrues estimated warranty costs at the time of sale. In general, manufactured products are warranted against defects in material and workmanship when properly used for their intended purpose, installed correctly, and appropriately maintained. Warranty periods depend on the nature of the product and range from one to five years. The amount of the accrued warranty liability is determined based on historical information such as past experience, product failure rates or number of units repaired, estimated cost of material and labor, and in certain instances estimated property damage. The accrued warranty liability is reviewed on a quarterly basis and may be adjusted as additional information regarding expected warranty costs becomes known.

The following is a rollforward of the Business’ accrued warranty liability for the years ended December 31, 2013 and 2012 ($ in thousands):

(11) LITIGATION AND CONTINGENCIES

The Business is, from time to time, subject to a variety of litigation and other proceedings incidental to its business, including lawsuits involving claims for damages arising out of the use of the Business’ products, software and services, claims relating to intellectual property matters, employment matters, commercial disputes, and personal injury as well as regulatory investigations or enforcement. The Business may also become subject to lawsuits as a result of past or future acquisitions or as a result of liabilities retained from, or representations, warranties or indemnities provided in connection with divested businesses. Some of these lawsuits may include claims for punitive and consequential as well as compensatory damages. Based upon the Business’ experience, current information and applicable law, it does not believe that these proceedings and claims will have a material adverse effect on its financial position, results of operations or cash flows.

While Danaher maintains workers compensation, property, cargo, automobile, crime, fiduciary, product, general liability, and directors’ and officers’ liability insurance on behalf of the Business that cover a portion of these claims, this insurance may be insufficient or unavailable to cover such losses. In addition, while the Business believes it is entitled to indemnification from third parties for some of these claims, these rights may also be insufficient or unavailable to cover such losses. Danaher maintains third party insurance policies on behalf of the Business up to certain limits to cover certain liability costs in excess of predetermined retained amounts. For general liability risk (which includes product liability) and most other insured risks, Danaher purchases outside insurance coverage only for severe losses (stop loss insurance) and reserves must be established and maintained with respect to amounts within the self-insured retention.

In accordance with accounting guidance, the Business records a liability in the combined financial statements for loss contingencies when a loss is known or considered probable and the amount can be reasonably estimated. If the reasonable estimate of a known or probable loss is a range, and no amount within the range is a better estimate than any other, the minimum amount of the range is accrued. If a loss does not meet the known or probable level but is reasonably possible and a loss or range of loss can be reasonably estimated, the estimated loss or range of loss is disclosed. These reserves consist of specific reserves for individual claims and additional amounts for anticipated developments of these claims as well as for incurred but not yet reported claims. The specific reserves for individual known claims are quantified with the assistance of legal counsel and outside risk insurance professionals where appropriate. In addition, outside risk insurance professionals assist in the

F-22

##### Table of Contents

determination of reserves for incurred but not yet reported claims through evaluation of the Business’ specific loss history, actual claims reported, and industry trends among statistical and other factors. Reserve estimates are adjusted as additional information regarding a claim becomes known. While the Business actively pursues financial recoveries from insurance providers, it does not recognize any recoveries until realized or until such time as a sustained pattern of collections is established related to historical matters of a similar nature and magnitude. If the risk insurance reserves established with respect to the Business are inadequate, the Business would be required to incur an expense equal to the amount of the loss incurred in excess of the reserves, which would adversely affect the Business’ net earnings.

In addition, the Business’ operations are subject to environmental laws and regulations in the jurisdictions in which they operate, which impose limitations on the discharge of pollutants into the ground, air and water and establish standards for the use, generation, treatment, storage and disposal of hazardous and non-hazardous wastes. Certain of the Business’ operations involve the handling, manufacturing, use or sale of substances that are or could be classified as hazardous materials within the meaning of applicable laws. The Business must also comply with various health and safety regulations in both the United States and abroad in connection with its operations. Compliance with these laws and regulations has not had and, based on current information and the applicable laws and regulations currently in effect, is not expected to have a material adverse effect on the Business’ capital expenditures, earnings or competitive position, and the Business does not anticipate material capital expenditures for environmental control facilities.

(12) INCOME TAXES

The operating results of the Business are included in the income tax returns of Danaher. The Business accounts for income taxes under the separate return method. Under this approach, the Business determines its current tax liability, deferred tax assets and liabilities and related tax expense as if it were filing separate tax returns in each tax jurisdiction.

Included in deferred income taxes as of December 31, 2013 are tax benefits for U.S. and non-U.S. net operating loss carry forwards totaling $23,075,000. Certain of the losses from 2013 may be carried forward indefinitely and others may be carried forward to various dates from 2014 through 2028.

The effective income tax rate for the years ended December 31 varies from the U.S. statutory federal income tax rate as follows:

|  | Percentage of Pre-Tax Earnings |
|  | 2013 |  |  | 2012 |  |  | 2011 |
Statutory federal income tax rate |  |  | 35.0 | % |  |  | 35.0 | % |  |  | 35.0 | %

Foreign income taxed at different rates than the U.S. statutory rate |  |  | 1.2 |  |  |  | (0.3 | ) |  |  | 1.3 |
Research and experimentation credits |  |  | (5.2 | ) |  |  | — |  |  |  | (2.1 | )
Domestic production activities deduction |  |  | (4.3 | ) |  |  | (2.7 | ) |  |  | (2.5 | )
Resolution and adjustment of uncertain tax positions/statute expirations |  |  | (1.7 | ) |  |  | (0.6 | ) |  |  | (4.5 | )
Other |  |  | 0.4 |  |  |  | 0.3 |  |  |  | 0.2 |
Effective income tax rate |  |  | 28.1 | % |  |  | 34.3 | % |  |  | 30.3 | %

The Business’ effective tax rate for each of 2013, 2012 and 2011 is lower than the U.S. federal statutory rate of 35% due principally to tax benefits of the Domestic Production Activities Deduction and the lapse of certain statutes of limitation, partially offset by state income taxes. For the years ended December 31, 2013 and 2011 the effective tax rate is also lower due to the research and experimentation credit, which for the year ended 2013 includes the benefit from the retroactive reinstatement of the credit for the year ended December 31, 2012 by the American Tax Relief Act of 2012.

As of December 31, 2013, gross unrecognized tax benefits totaled approximately $5,952,000 ($6,314,000, including $362,000 associated with potential interest and penalties). As of December 31, 2012, gross unrecognized tax benefits totaled approximately $5,677,000 ($6,027,000, including $350,000 associated with

potential interest and penalties). The Business recognized approximately $145,000, $120,000, and $91,000 of interest and penalties associated with uncertain tax positions for the years ended December 31, 2013, 2012 and 2011, respectively. To the extent unrecognized tax benefits including interest and penalties are not assessed with respect to uncertain tax positions, substantially all amounts accrued will be reduced and reflected as a reduction of the overall income tax provision.

By virtue of previously filed separate company and consolidated tax returns of Danaher that cover the Business, the Business is routinely under audit by federal, state, local and foreign income tax authorities including with respect to the timing and amount of deductions and the allocation of income among various tax jurisdictions. Income taxes payable include amounts considered sufficient to pay assessments that may result from examination of prior year returns; however, the amount paid upon resolution of issues raised may differ from the amount provided.

The Internal Revenue Service is currently examining the Danaher consolidated tax returns for the years ended December 31, 2010 and 2011, which includes the operations of the Business. The statute of limitations for these years has been extended to September 15, 2015. In addition, various other Danaher consolidated tax returns which include the Business are currently under examination, the more significant jurisdictions are Germany, California and Illinois for tax years December 31, 2005 and subsequent. These examinations are expected to be completed no later than 2016.

Management estimates that it is reasonably possible that the amount of unrecognized tax benefits may be reduced by approximately $345,000 within twelve months as a result of resolution of worldwide tax matters, tax audit settlements and/or statute expirations.

The Business provides income taxes for unremitted earnings of foreign subsidiaries that the Business does not consider indefinitely reinvested overseas. As of December 31, 2013, the approximate amount of earnings from foreign subsidiaries that the Business considers indefinitely reinvested and for which deferred taxes have not been provided was approximately $35,029,000. United States income taxes have not been provided on earnings that are planned to be reinvested indefinitely outside the United States and the amount of such taxes that may be applicable is not readily determinable given the various tax planning alternatives the Business could employ should it decide to repatriate these earnings.

(13) STOCK-BASED COMPENSATION

The Business has no stock-based compensation plans; however, certain employees of the Business are eligible to participate in Danaher’s stock-based compensation plans, which include stock options and restricted stock units (“RSUs”). The expense associated with the Business’ employees who participate in the Plans is allocated to the Business in the accompanying Combined Statements of Earnings. All current grants of stock options and RSUs are made under Danaher’s 2007 Stock Incentive Plan (the “2007 Plan”). The 2007 Plan provides for the grant of stock options, stock appreciation rights, RSUs, restricted stock or any other stock based award. Stock options and

##### Table of Contents

RSUs have also been issued to employees of the Business under Danaher’s 1998 Stock Option Plan (together with the 2007 Plan, the “Plans”), which operates in a similar manner to the 2007 Plan, but no further equity awards will be issued under the 1998 Stock Option Plan. No more than 19 million of the 62 million authorized shares under the 2007 Plan may be granted in any form other than stock options or stock appreciation rights. As of December 31, 2013, approximately 29 million shares of Danaher’s common stock were reserved for issuance under the 2007 Plan.

Stock options granted under the Plans generally vest pro-rata over a five-year period and terminate ten years from the grant date, though the specific terms of each grant are determined by the Compensation Committee of Danaher’s Board of Directors (“Compensation Committee”). Certain employees of the Business have been awarded options with different vesting criteria. Option exercise prices for options under these plans are equal to the closing price of Danaher’s common stock on the NYSE on the date of grant.

RSUs issued under the Plans provide for the issuance of a share of Danaher’s common stock at no cost to the holder, generally vest pro-rata over a five-year period and terminate ten years from the grant date, though the specific terms of each grant are determined by the Compensation Committee. Certain employees of the Business have been awarded RSUs with different vesting criteria.

The options and RSUs generally vest only if the employee is employed by Danaher on the vesting date or in other limited circumstances and unvested options and RSUs are forfeited upon retirement before age 65 unless the Compensation Committee determines otherwise. In connection with the Transaction, Danaher has agreed to (i) allow stock options held by Business employees that are scheduled to vest between the closing date and August 4, 2015 to vest in accordance with their terms and remain exercisable for up to 90 days following such vesting date, and (ii) allow RSUs held by Business employees that are scheduled to vest between the closing date and August 4, 2015 to vest in accordance with their terms.

Option activity under the Company’s stock plans as of December 31, 2013 and changes during the year ended December 31, 2013 were as follows (in thousands; except exercise price and number of years):

|  | Options |  |  | Weighted Average Exercise Price |  |  | Weighted Average Remaining Contractual Term (in Years) |  |  | Aggregate Intrinsic Value |

##### Table of Contents

The following table summarizes information on unvested RSUs activity during the year ended December 31, 2013 (in thousands; except grant date fair value):

|  | Number of RSUs |  |  | Weighted Average Grant-Date Fair Value |
Unvested at December 31, 2012 |  |  | 214 |  |  |  | 45.01 |
Granted |  |  | 83 |  |  |  | 65.39 |
Vested |  |  | (60 | ) |  |  | 40.80 |
Forfeited |  |  | — |  |  |  | — |
Unvested at December 31, 2013 |  |  | 237 |  |  |  | 53.15 |

The Business accounts for stock-based compensation by measuring the cost of employee services received in exchange for all equity awards granted, including stock options and RSUs, based on the fair value of the award as of the grant date. The Business recognizes the compensation expense over the requisite service period (which is generally the vesting period but may be shorter than the vesting period if the employee becomes retirement eligible before the end of the vesting period). The fair value for RSU awards was calculated using the closing price of Danaher’s common stock on the date of grant. The fair value of the options granted was calculated using a Black-Scholes Merton option pricing model (“Black-Scholes”).

The following summarizes the assumptions used in the Black-Scholes model to value options granted during the years ended December 31, 2013, 2012 and 2011:

|  | Year Ended December 31 |
|  | 2013 |  |  | 2012 |  |  | 2011 |
Risk-free interest rate |  |  | 1.0 – 1.7 | % |  |  | 0.7 – 1.1 | % |  |  | 1.2 – 2.6 | %
Weighted average volatility |  |  | 23.5 | % |  |  | 29.4 | % |  |  | 28.3 | %
Dividend yield |  |  | 0.2 | % |  |  | 0.2 | % |  |  | 0.2 | %
Expected years until exercise |  |  | 6.0 |  |  |  | 6.0 |  |  |  | 6.0 |

The Black-Scholes model incorporates assumptions to value stock-based awards. The risk-free rate of interest for periods within the contractual life of the option is based on a zero-coupon U.S. government instrument whose maturity period equals or approximates the option’s expected term. Expected volatility is based on implied volatility from traded options on Danaher’s stock and historical volatility of Danaher’s stock. The dividend yield is calculated by dividing Danaher’s annual dividend, based on the most recent quarterly dividend rate, by the closing stock price on the grant date. To estimate the option exercise timing used in the valuation model, in addition to considering the vesting period and contractual term of the option, the Business analyzes and considers actual historical exercise experience for previously granted options. At the time of grant, the Business estimates the number of options that it expects will be forfeited based on historical experience.

The Business recognized approximately $8,106,000, $6,167,000 and $2,821,000 during the years ended December 31, 2013, 2012 and 2011, respectively, of non-cash pre-tax compensation expense associated with share-based compensation programs. This expense was allocated to the Business based on the cost directly attributable to the Business’ employees that participate in the share-based compensation program and has been recognized as a component of selling, general and administrative expenses in the accompanying Combined Statements of Earnings. As of December 31, 2013, $9,949,000 and $9,135,000 of total unrecognized compensation cost related to RSUs and stock options, respectively, are expected to be recognized over a weighted average period of approximately three years. These amounts will be adjusted for any future changes in estimated forfeitures.

(14) RESTRUCTURING AND OTHER RELATED CHARGES

During 2013, 2012 and 2011, the Business recorded restructuring and other related charges of $5,529,000, $2,340,000 and $3,421,000, respectively; of which approximately 91%, 55% and 89%, in each respective year was included in selling general and administrative expenses in the accompanying Combined Statements of Earnings, with the remaining amount charged to cost of sales.

The Business’ restructuring and related activities were focused on improvements in operational efficiency through targeted workforce reductions. These costs were incurred to position the Business to provide superior products and services to its customers in a cost efficient manner, and taking into consideration broad economic uncertainties.

Substantially all restructuring activities initiated in 2013 were completed by December 31, 2013 and substantially all cash payments associated with remaining termination benefits have been paid in 2014. As of December 31, 2013 and 2012, the Business had accrued restructuring charges of $5,611,000 and $2,591,000, respectively, included in accrued expenses and other liabilities in the accompanying Combined Balance Sheets.

(15) SEGMENT INFORMATION

The Business is comprised of certain operating units of Danaher and is a premier global provider of network management tools and security solutions for telecommunications carriers and network enterprise customers. Given the interrelationships between products, technologies and customers, and resulting similar long-term economic characteristics, the Business meets the criteria for aggregating its three operating segments into a single reportable segment.

(16) RELATED-PARTY TRANSACTIONS

The Business has historically operated as part of Danaher and not as a stand-alone company. Accordingly, certain shared costs have been allocated to the Business and are reflected as expenses in these financial statements. Management considers the allocation methodologies used to be reasonable and appropriate reflections of the related expenses attributable to the Business for purposes of the carve-out financial statements; however, the expenses reflected in these financial statements may not be indicative of the actual expenses that would have been incurred during the periods presented if the Business had operated as a separate stand-alone entity. In addition, the expenses reflected in the financial statements may not be indicative of expenses that will be incurred in the future by the Business.

Corporate Expenses

Certain corporate overhead and other shared expenses incurred by Danaher and its subsidiaries have been allocated to the Business and are reflected in the Combined Statements of Earnings. These amounts include, but are not limited to, items such as general management and executive oversight, costs to support Danaher information technology infrastructure, facilities, compliance, human resources, marketing and legal functions and financial management and transaction processing including public company reporting, consolidated tax filings and tax planning, Danaher benefit plan administration, risk management and consolidated treasury services, certain employee benefits and incentives, and stock based compensation administration. These costs are allocated using methodologies that management believes are reasonable for the item being allocated. Allocation methodologies include the Business’ relative share of revenues, headcount, or functional spend as a percentage of the total.

Insurance Programs Administered by Danaher

In addition to the corporate allocations noted above, the Business was allocated expenses related to certain insurance programs Danaher administers on behalf of the Business, including automobile liability, workers’ compensation, general liability, product liability and property insurance. These amounts are allocated using various methodologies, as described below.

Included within the insurance cost allocation are allocations related to non-property casualty programs (automobile liability, workers’ compensation and general liability) for which Danaher is self-insured up to a certain amount. For the self-insured component, costs are allocated to the Business based on incurred claims of the Business. Danaher has premium based policies which cover amounts in excess of the self-insured retentions. The Business is allocated a portion of the total insurance cost incurred by Danaher based on its pro-rata portion of Danaher’s total underlying exposure base (e.g., number and type of vehicles, sales, payroll dollars, etc.). An estimated liability relating to the Business’ known and incurred but not reported claims has been allocated to the Business and reflected on the accompanying Combined Balance Sheets.

##### Table of Contents

Also included within the insurance allocation is coverage related to property insurance. The Business is allocated a portion of the total insurance cost incurred by Danaher based on its pro-rata portion of Danaher’s total insured property values.

Medical Insurance Programs Administered by Danaher

In addition to the corporate allocations noted above, the Business was allocated expenses related to the medical insurance programs Danaher administers on behalf of the Business. These amounts were allocated using actual medical claims incurred during the period for the associated employees attributable to the Business.

Deferred Compensation Program Administered by Danaher

Certain employees of the Business participate in Danaher’s nonqualified deferred compensation programs that permit officers, directors and certain management employees to defer a portion of their compensation, on a pre-tax basis, until their termination of employment. Participants may choose among alternative earning rates for the amounts they defer, which are primarily based on investment options within the Danaher’s 401(k) program (except that the earnings rates for amounts contributed unilaterally by the Business are entirely based on changes in the value of Danaher’s common stock). All amounts deferred under this plan are unfunded, unsecured obligations of the Business.

The amounts of related party expenses allocated to the Business from Danaher and its subsidiaries for the years ended December 31, 2013, 2012 and 2011, were as follows ($ in thousands):

COMMUNICATIONS BUSINESS OF DANAHER CORPORATION

NOTES TO COMBINED CONDENSED FINANCIAL STATEMENTS

(unaudited)

(1) BUSINESS OVERVIEW AND BASIS OF PRESENTATION

The accompanying unaudited condensed combined financial statements present the historical financial position, results of operations and cash flows of the Communications Business of Danaher Corporation (the “Business”) in accordance with accounting principles generally accepted in the United States of America “(GAAP)” for the preparation of carved-out combined condensed financial statements. The combined condensed financial statements included herein should be read in conjunction with the combined financial statements and accompanying notes as of December 31, 2013 and 2012 and for the three years ended December 31, 2013, 2012 and 2011 included elsewhere in this information statement. In the opinion of management, the financial data presented includes all adjustments necessary to present fairly the financial position of the Business as of September 26, 2014 and December 31, 2013, and its results of operations and cash flows for the nine months ended September 26, 2014 and September 27, 2013.

The Business consists of certain operating units of Danaher Corporation (“Danaher”) and is a premier global provider of network management tools and security solutions for telecommunications carriers and network enterprise customers. The Business’ products enable organizations to gain unique and encompassing real-time analytical insights to better design, deploy, monitor and secure the traditional, virtualized, mobile and cloud-based networks operated by communication service providers, hosters, enterprises and government agencies worldwide. The Business’ products simplify the complexity of understanding and effectively managing the underlying network technologies, communication services and subscriber interactions.

On October 13, 2014, Danaher announced a definitive agreement with NetScout Systems, Inc. (“NetScout”) to combine the Business with NetScout (the “Transaction”). The Transaction will be structured as a distribution of the Business to Danaher shareholders in either a spin-off transaction, a split-off transaction, or a combination split-off and spin-off, followed by a merger with a subsidiary of NetScout for consideration of 62.5 million NetScout shares, subject to adjustment. Both the distribution and merger are expected to qualify as tax-free transactions to Danaher and its shareholders, except to the extent that cash is paid to Danaher stockholders in lieu of fractional shares. If Danaher elects a spin-off, all Danaher shareholders will participate pro-rata. If Danaher elects a split-off, Danaher will conduct an exchange offer pursuant to which its shareholders will elect whether to exchange Danaher shares for common units of the Business. If the split-off exchange offer is not fully subscribed, the additional Business common units held by Danaher will be distributed in a spin-off on a pro rata basis to Danaher shareholders. Danaher will determine which approach it will take prior to closing the transaction and no decision has been made at this time. The transaction remains subject to approval by NetScout’s shareholders and the satisfaction of customary closing conditions, including regulatory approvals and the absence of a material adverse change with respect to each of the Business and NetScout. At closing, depending on the number of shares of NetScout common stock outstanding, Danaher shareholders will receive approximately 59.5% of the shares of NetScout stock outstanding following the combination. The Transaction is expected to be completed in 2015.

The Business has historically operated as part of Danaher and not as a stand-alone company and has no separate legal status or existence. The financial statements have been derived from Danaher’s historical accounting records and are presented on a carve-out basis. All revenues and costs as well as assets and liabilities directly associated with the business activity of the Business are included as a component of the financial statements. The financial statements also include allocations of certain general, administrative, sales and marketing expenses and cost of sales from Danaher’s corporate office and from other Danaher businesses to the Business and allocations of related assets, liabilities, and Parent’s investment, as applicable. The allocations have been determined on a reasonable basis; however, the amounts are not necessarily representative of the amounts that would have been reflected in the financial statements had the Business been an entity that operated independently of Danaher. Related party allocations are discussed further in Note 11.

As part of Danaher, the Business is dependent upon Danaher for all of its working capital and financing requirements as Danaher uses a centralized approach to cash management and financing of its operations.

##### Table of Contents

Financial transactions relating to the Business are accounted for through the Parent investment account of the Business. Accordingly, none of Danaher’s cash, cash equivalents or debt at the corporate level has been assigned to the Business in the financial statements.

Net parent investment, which includes retained earnings, represents Danaher’s interest in the recorded net assets of the Business. All significant transactions between the Business and Danaher have been included in the accompanying combined condensed financial statements. Transactions with Danaher are reflected in the accompanying Combined Condensed Statements of Cash Flows as “Net transfers to parent” and in the accompanying Combined Condensed Balance Sheets within “Net parent investment”.

All significant intercompany accounts and transactions between the operations comprising the Business have been eliminated in the accompanying financial statements.

Sales to the Business’ largest two customers were 31% of total sales during the nine months ended September 26, 2014, and 38% of total sales during the nine months ended September 27, 2013. No other individual customer accounted for more than 10% of combined sales during these periods. Accounts receivable from these customers was 18% of total receivables as of September 26, 2014, and 11% as of December 31, 2013.

Accumulated Other Comprehensive Loss—Accumulated other comprehensive loss of $10,148,000 and $4,401,000 as of September 26, 2014, and December 31, 2013, respectively, consists of accumulated foreign currency translation adjustments and pension adjustments. Foreign currency translation adjustments are generally not adjusted for income taxes as they relate to indefinite investments in non-U.S. subsidiaries. For the nine months ended September 26, 2014, and September 27, 2013, there were no reclassifications out of accumulated other comprehensive income loss.

Recently Issued Accounting Pronouncements—In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606) , which impacts virtually all aspects of an entity’s revenue recognition. The core principle of the new standard is that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard is effective for annual reporting periods beginning after December 15, 2016. Management has not yet completed its assessment of the impact of the new standard, including possible transition alternatives, on the Business’ financial statements.

(2) ACQUISITIONS

For a description of the Business’ acquisition activity for the year ended December 31, 2013, reference is made to Note 3 of the financial statements as of and for the year ended December 31, 2013 included elsewhere in this information statement.

The Business continually evaluates potential acquisitions that either strategically fit with the Business’ existing portfolio or expand the Business’ portfolio into a new and attractive business area. There were no acquisitions completed by the Business during the nine months ended September 26, 2014. The Business spent $12,500,000 to acquire certain technology related assets in a business combination during the nine months ended September 27, 2013.

(3) INVENTORIES

The classes of inventory are summarized as follows ($ in thousands):

|  | September 26, 2014 |  |  | December 31, 2013 |
Finished goods |  | $ | 20,710 |  |  | $ | 28,852 |
Work in process |  |  | 10,667 |  |  |  | 9,041 |
Raw materials |  |  | 9,775 |  |  |  | 15,862 |

(6) FAIR VALUE MEASUREMENTS

Accounting standards define fair value based on an exit price model, establish a framework for measuring fair value where the Business assets and liabilities are required to be carried at fair value and provide for certain disclosures related to the valuation methods used within a valuation hierarchy as established within the accounting standards. This hierarchy prioritizes the inputs into three broad levels as follows. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets in markets that are not active, or other observable characteristics for the asset or liability, including interest rates, yield curves and credit risks, or inputs that are derived principally from, or corroborated by, observable market data through correlation. Level 3 inputs are unobservable inputs based on the Business’ assumptions. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement in its entirety.

A summary of financial assets and liabilities that are measured at fair value on a recurring basis as of September 26, 2014, and December 31, 2013 were as follows ($ in thousands):

|  | Quoted Prices in Active Market (Level 1) |  |  | Significant Other Observable Inputs (Level 2) |  |  | Significant Unobservable Inputs (Level 3) |  |  | Total |
September 26, 2014: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Liabilities: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Deferred compensation plans |  | $ | — |  |  | $ | 1,623 |  |  | $ | — |  |  | $ | 1,623 |
Earn-out obligations |  |  | — |  |  |  | — |  |  |  | 22,921 |  |  |  | 22,921 |
December 31, 2013: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Liabilities: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Deferred compensation plans |  | $ | — |  |  | $ | 1,498 |  |  | $ | — |  |  | $ | 1,498 |
Earn-out obligations |  |  | — |  |  |  | — |  |  |  | 24,896 |  |  |  | 24,896 |

For more information on the deferred compensation programs see Note 11.

For more information on earn-out obligations, see Note 3 of the combined financial statements as of for the year ended December 31, 2013.

There have been no transfers of assets or liabilities between the fair value measurement levels. The following table is a reconciliation of the fair value measurements that use significant unobservable inputs (Level 3), which consist of earn-out obligations related to acquisitions made in 2013 ($ in thousands):

Fair value as of December 31, 2013 |  | $ | 24,896 |
Payments |  |  | (2,500 | )
Adjustment of earn-out liability recorded through earnings |  |  | 525 |
Fair value as of September 26, 2014 |  | $ | 22,921 |

(7) PENSION BENEFIT PLANS

Certain of the Business’ non-U.S. employees participate in certain of Danaher’s noncontributory defined benefit pension plans. None of the Business’ employees in the U.S. participate in any Danaher noncontributory defined benefit pension plans. In general, these plans are funded based on considerations relating to legal requirements, underlying asset returns, the plan’s funded status, the anticipated deductibility of the contribution, local practices, market conditions, interest rates and other factors.

F-39

##### Table of Contents

The following sets forth the components of the Business’ net periodic pension cost of the noncontributory defined benefit pension plans ($ in thousands):

|  | Nine Months Ended |
|  | September 26, 2014 |  |  | September 27, 2013 |
Service cost |  | $ | 329 |  |  | $ | 251 |
Interest cost |  |  | 220 |  |  |  | 170 |
Expected return on plan assets |  |  | (67 | ) |  |  | (50 | )
Net periodic pension cost |  | $ | 482 |  |  | $ | 371 |

Expected Contributions

During 2013, the Business did not make any contributions to its defined benefit pension plans. During 2014, the Business cash contribution requirements for its defined benefit pension plans are expected to be approximately $93,000.

As the participants within the Business’ plans are all active employees, the benefit payments are not expected to be material in the foreseeable future.

Other Matters

Substantially all employees not covered by defined benefit plans are covered by defined contribution plans, which generally provide for Business funding based on a percentage of compensation. Expense for all defined benefit pension and defined contribution plans amounted to $7,081,000 and $6,305,000 for the nine months ended September 26, 2014, and September 27, 2013, respectively.

(8) INCOME TAXES

The Business’ effective tax rate for the nine months ended September 26, 2014 and September 27, 2013, was 31.2% and 28.7%, respectively. The effective tax rate for 2014 and 2013 is lower than the U.S. federal statutory rate of 35% due principally to tax benefits of the Domestic Production Activities Deduction, partially offset by state income taxes. In addition, the effective tax rate in 2013 is also lower due to the research and experimentation credit, which includes the benefit from the retroactive reinstatement of the credit for the year-ended December 31, 2012 by the American Tax Relief Act of 2012.

(9) RESTRUCTURING AND OTHER RELATED CHARGES

During the nine months ended September 26, 2014, and September 27, 2013, the Business recorded restructuring and other related charges of $869,000 and $76,000, respectively; of which 100% and 10% in each respective year was included in selling general and administrative expenses in the accompanying Condensed Combined Statements of Earnings, with the remaining amount charged to cost of sales.

The Business’ restructuring and related activities are focused on improvements in operational efficiency through targeted workforce reductions. These costs are incurred to position the Business to provide superior products and services to its customers in a cost efficient manner, and taking into consideration broad economic uncertainties.

Substantially all restructuring activities initiated in 2014 are expected to be completed by December 31, 2014, and substantially all cash payments associated with remaining termination benefits will be paid in 2015. As of September 26, 2014 and December 31, 2013, the Business had accrued restructuring charges of $958,000 and $5,611,000, respectively, included in accrued expenses and other liabilities in the accompanying Combined Condensed Balance Sheets.

The table below shows the rollforward of the accrual balance ($ in thousands).

|  | Total |
Balance, December 31, 2013 |  | $ | 5,611 |
Costs incurred |  |  | 869 |
Paid/Settled |  |  | (5,522 | )
Balance, September 26, 2014 |  | $ | 958 |

(10) COMMITMENTS AND CONTINGENCIES

For a description of the Business’ litigation and contingencies, reference is made to Note 11 of the Business’ combined financial statements as of and for the year ended December 31, 2013.

The Business generally accrues estimated warranty costs at the time of sale. In general, manufactured products are warranted against defects in material and workmanship when properly used for their intended purpose, installed correctly and appropriately maintained. Warranty period terms depend on the nature of the product and range from ninety days up to the life of the product. The amount of the accrued warranty liability is determined based on historical information such as past experience, product failure rates or number of units repaired, estimated cost of material and labor, and in certain instances, estimated property damage. The accrued warranty liability is reviewed on a quarterly basis and may be adjusted as additional information regarding expected warranty costs becomes known.

The following is a rollforward of the Business’ accrued warranty liability ($ in thousands):

Balance, December 31, 2013 |  | $ | 1,132 |
Accruals for warranties issued during the period |  |  | 648 |
Settlements made |  |  | (415 | )
Balance, September 26, 2014 |  | $ | 1,365 |

(11) RELATED PARTY TRANSACTIONS

The Business has historically operated as part of Danaher and not as a stand-alone company. Accordingly, certain shared costs have been allocated to the Business and are reflected as expenses in these financial statements. Management considers the allocation methodologies used to be reasonable and appropriate reflections of the related expenses attributable to the Business for purposes of the carve-out financial statements; however, the expenses reflected in these financial statements may not be indicative of the actual expenses that would have been incurred during the periods presented if the Business had operated as a separate stand-alone entity. In addition, the expenses reflected in the financial statements may not be indicative of expenses that will be incurred in the future by the Business.

Corporate Expenses

Certain corporate overhead and other shared expenses incurred by Danaher and its subsidiaries have been allocated to the Business and are reflected in the Combined Statements of Earnings. These amounts include, but are not limited to, items such as general management and executive oversight, costs to support Danaher information technology infrastructure, facilities, compliance, human resources, marketing and legal functions and financial management and transaction processing including public company reporting, consolidated tax filings and tax planning, Danaher benefit plan administration, risk management and consolidated treasury services, certain employee benefits and incentives, and stock based compensation administration. These costs are allocated using methodologies that management believes are reasonable for the item being allocated. Allocation methodologies include the Business’ relative share of revenues, headcount, or functional spend as a percentage of the total.

F-41

##### Table of Contents

Insurance Programs Administered by Danaher

In addition to the corporate allocations noted above, the Business was allocated expenses related to certain insurance programs Danaher administers on behalf of the Business, including automobile liability, workers’ compensation, general liability, product liability and property insurance. These amounts are allocated using various methodologies, as described below.

Included within the insurance cost allocation are allocations related to non-property casualty programs (automobile liability, workers’ compensation and general liability) for which Danaher is self-insured up to a certain amount. For the self-insured component, costs are allocated to the Business based on incurred claims of the Business. Danaher has premium based policies which cover amounts in excess of the self-insured retentions. The Business is allocated a portion of the total insurance cost incurred by Danaher based on its pro-rata portion of Danaher’s total underlying exposure base (e.g., number and type of vehicles, sales, payroll dollars, etc.). An estimated liability relating to the Business’ known and incurred but not reported claims has been allocated to the Business and reflected on the accompanying Combined Balance Sheets.

Also included within the insurance allocation is coverage related to property insurance. The Business is allocated a portion of the total insurance cost incurred by Danaher based on its pro-rata portion of Danaher’s total insured property values.

Medical Insurance Programs Administered by Danaher

In addition to the corporate allocations noted above, the Business was allocated expenses related to the medical insurance programs Danaher administers on behalf of the Business. These amounts were allocated using actual medical claims incurred during the period for the associated employees attributable to the Business. Had these medical insurance programs been administered by the Business as a separate entity, the amounts may have been different than those allocated to the Business.

Deferred Compensation Program Administered by Danaher

Certain employees of the Business participate in Danaher’s nonqualified deferred compensation programs that permit officers, directors and certain management employees to defer a portion of their compensation, on a pre-tax basis, until their termination of employment. Had the deferred compensation program been administered by the Business as a separate entity, the amounts may have been different than those allocated to the Business. Participants may choose among alternative earning rates for the amounts they defer, which are primarily based on investment options within the Danaher’s 401(k) program (except that the earnings rates for amounts contributed unilaterally by the Business are entirely based on changes in the value of Danaher’s common stock). All amounts deferred under this plan are unfunded, unsecured obligations of the Business.

To the Board of Directors and Stockholders of Danaher Corporation

We have audited the accompanying balance sheet of Potomac Holding LLC (the Company), a wholly-owned business of Danaher Corporation, as of September 29, 2014. This balance sheet is the responsibility of the Company’s management. Our responsibility is to express an opinion on this balance sheet based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statement is free of material misstatement. We were not engaged to perform an audit of the Company’s internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing 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 over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the balance sheet referred to above presents fairly, in all material respects, the financial position of Potomac Holding LLC at September 29, 2014 in conformity with U.S. generally accepted accounting principles.

NOTE TO THE BALANCE SHEET

(1) BUSINESS OVERVIEW AND BASIS OF PRESENTATION

Potomac Holding LLC (“Newco”) is a Delaware limited liability company and a wholly owned subsidiary of Danaher Corporation (“Danaher”). On September 29, 2014, Danaher caused Newco to be formed in order to facilitate the separation of the Communications Business of Danaher Corporation (the “Communications Business” or the “Business”) from Danaher. Newco has engaged in no business operations to date and at September 29, 2014 it had no assets or liabilities.

The accompanying balance sheet presents the historical financial position of Newco in accordance with accounting principles generally accepted in the United States of America (“GAAP”).

On October 13, 2014, Danaher announced a definitive agreement with NetScout Systems, Inc. (“NetScout”) to combine the Business with NetScout (the “Transaction”). Prior to the closing of the Transaction the Business will be transferred to Newco. The Transaction will be structured as a distribution of Newco to Danaher shareholders in either a spin-off transaction, a split-off transaction, or a combination split-off and spin-off, followed by a merger with a subsidiary of NetScout for consideration of 62.5 million NetScout shares, subject to adjustment. Both the distribution and merger are expected to qualify as tax-free transactions to Danaher and its shareholders, except to the extent that cash is paid to Danaher stockholders in lieu of fractional shares. If Danaher elects a spin-off, all Danaher shareholders will participate pro-rata. If Danaher elects a split-off, Danaher will conduct an exchange offer pursuant to which its shareholders will elect whether to exchange Danaher shares for common units of Newco. If the split-off exchange offer is not fully subscribed, the additional Newco common units held by Danaher will be distributed in a spin-off on a pro rata basis to Danaher shareholders. Danaher will determine which approach it will take prior to closing the transaction and no decision has been made at this time. The transaction remains subject to approval by NetScout’s shareholders and the satisfaction of customary closing conditions, including regulatory approvals and the absence of a material adverse change with respect to each of the Business and NetScout. At closing, depending on the number of shares of NetScout common stock outstanding, Danaher shareholders will receive approximately 59.5% of the shares of NetScout stock outstanding following the combination. The Transaction is expected to be completed in 2015.

(b) If, during the period from the date of this Agreement through the Effective Time, the outstanding Newco Common Units or shares of NetScout Common Stock are changed into a different number or class of shares by reason of any stock or interest split, division or subdivision of shares, stock dividend, distribution of limited liability company interests, reverse stock or interest split, combination of shares, reclassification, recapitalization or other similar transaction, or if a distribution of limited liability company interests or stock dividend is declared by Newco or NetScout, respectively, during such period, then the payment calculations set forth in Section 1.5(a)(iii) shall be adjusted to the extent appropriate to provide the same economic effect as contemplated by this Agreement prior to such action.

(c) If any Newco Membership Interest outstanding immediately prior to the Effective Time is unvested or is subject to a repurchase option, risk of forfeiture or other condition under any applicable restricted equity purchase agreement or other Contract with Newco or under which Newco has any rights, then (except to the extent provided in any binding agreement between Newco and the holder thereof): (i) the shares of NetScout Common Stock issued in exchange for such Newco Membership Interests will also be unvested and subject to the same repurchase option, risk of forfeiture or other condition; and (ii) such shares of NetScout Common Stock, whether represented by certificates or in book entry form, may accordingly be marked with appropriate legends. Prior to the Effective Time, Newco shall ensure that, from and after the Effective Time, NetScout or the First Merger Surviving Entity or Second Merger Surviving Entity, as applicable, is entitled to exercise any such repurchase option or other right set forth in any such restricted stock or interest purchase agreement or other Contract.

(d) No fractional shares of NetScout Common Stock shall be issued in connection with the First Merger, and no certificates or scrip for any such fractional shares shall be issued. Any holder of Newco Membership Interests who would otherwise be entitled to receive a fraction of a share of NetScout Common Stock (after aggregating all fractional shares of NetScout Common Stock issuable to such holder) shall, in lieu of such fraction of a share, be paid in cash the dollar amount (rounded to the nearest whole cent), after deducting any required withholding taxes, on a pro rata basis, without interest, determined by multiplying such fraction by the closing price of a share of NetScout Common Stock on the NASDAQ Global Select Market on the last business day prior to the date on which the First Merger becomes effective. Payment of cash in lieu of fractional shares of NetScout Common Stock shall be made solely for the purpose of avoiding the expense and inconvenience to NetScout of issuing fractional shares of NetScout Common Stock and shall not represent separately bargained-for consideration.

1.6 Exchange of Newco Membership Interests.

(a) Pursuant to Article III of the Distribution Agreement, the Exchange Agent (as defined below) shall hold, for the account of the relevant Danaher stockholders, the global certificate(s) representing all of the outstanding Newco Common Units distributed in the Distribution. Such Newco Common Units shall be converted into shares of NetScout Common Stock in accordance with the terms of this Section 1.

(b) Prior to the Closing Date, Danaher shall appoint a reputable bank or trust company reasonably satisfactory to NetScout as exchange agent in the First Merger (the “Exchange Agent”).

For the purposes of such deposit, NetScout will assume that there will not be any fractional shares of NetScout Common Stock. NetScout will make available to the Exchange Agent, for addition to the Exchange Fund, from time to time as needed or as reasonably requested by Danaher, cash sufficient to pay cash in lieu of fractional shares in accordance with Section 1.5(d). Following the Effective Time, the Exchange Agent shall, pursuant to irrevocable instructions, deliver the NetScout Common Stock to be issued pursuant to this Section 1 from the shares of NetScout Common Stock held in the Exchange Fund. The Exchange Fund shall not be used for any other purpose.

(c) Promptly after the Effective Time, and to the extent not previously distributed in connection with the Distribution, the Exchange Agent will mail to the Persons who were record holders of Newco Membership Interests immediately prior to the Effective Time: (i) a letter of transmittal in customary form; and (ii) instructions for use in effecting the exchange of any Newco Membership Interests for the Per Share Merger Consideration. Upon surrender of a duly executed letter of transmittal, together with such other customary documents as may be reasonably required by the Exchange Agent or NetScout, the holder of such Newco Membership Interests shall be entitled to receive, and the Exchange Agent shall (and NetScout shall cause the Exchange Agent to) in exchange therefor transfer from the Exchange Fund to such holder the number of whole shares of NetScout Common Stock that such holder has the right to receive pursuant to the provisions of Section 1.5(a)(iii) (and cash in lieu of any fractional share of NetScout Common Stock pursuant to Section 1.5(d) and any dividends or other distributions pursuant to Section 1.6(d)). From and after the Effective Time, any certificates formerly representing Newco Membership Interests will represent only the right to receive shares of NetScout Common Stock (and cash in lieu of any fractional share of NetScout Common Stock as contemplated by Section 1.5(d) and any dividends or other distributions pursuant to Section 1.6(d)).

(d) No dividends or other distributions declared or made with respect to NetScout Common Stock with a record date after the Effective Time shall be paid or otherwise delivered to the holder of any unsurrendered Newco Membership Interest with respect to the shares of NetScout Common Stock that such holder has the right to receive in the First Merger until such holder exchanges such Newco Membership Interest in accordance with this Section 1.6 (at which time such holder shall be entitled, subject to the effect of applicable abandoned property law, escheat law or other Legal Requirement, to receive all such dividends and distributions theretofore paid or, at the appropriate payment date, payable, in each case, without interest). NetScout shall deposit all such dividends and distributions in the Exchange Fund.

(e) Any portion of the Exchange Fund that remains undistributed to holders of unexchanged Newco Membership Interests as of the date that is one year after the Effective Time shall be delivered to NetScout upon demand, and any holders of Newco Membership Interests who have not theretofore exchanged their Newco Membership Interests in accordance with this Section 1.6 shall thereafter look only to NetScout for satisfaction of their claims for NetScout Common Stock, cash in lieu of fractional shares of NetScout Common Stock as contemplated by Section 1.5(d) and any dividends or distributions pursuant to Section 1.6(d) with respect to shares of NetScout Common Stock, in each case without interest thereon.

(f) Each of the Exchange Agent, NetScout and the First Merger Surviving Entity or Second Merger Surviving Entity, as applicable, shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable pursuant to this Agreement to any holder or former holder of Newco Membership Interest such amounts as may be required to be deducted or withheld from such consideration under the Code or any provision of state, local or foreign tax law or under any other applicable Legal Requirement. To the extent such amounts are so deducted or withheld and paid to the appropriate Governmental Body, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

(g) Neither NetScout nor the First Merger Surviving Entity nor Second Merger Surviving Entity shall be liable to any holder or former holder of Newco Membership Interests or to any other Person with respect to any shares of NetScout Common Stock (or dividends or distributions with respect thereto), or for any cash amounts, required to be delivered to any public official pursuant to any applicable abandoned property law, escheat law or other Legal Requirement.

1.7 Closing of Transfer Books. From and after the Effective Time, the membership transfer books of Newco shall be closed and no transfer shall be made of any Newco Membership Interests that were outstanding as of the Effective Time.

1.8 Tax Consequences. For U.S. federal income tax purposes, the Mergers are intended to be treated as integrated steps in a single transaction and together qualify as a reorganization within the meaning of

A-5

##### Table of Contents

Section 368(a)(1) of the Code. The parties to this Agreement adopt this Agreement as a “plan of reorganization” within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the U.S. Treasury Regulations. Each party hereto shall cause all Tax Returns relating to the Mergers filed by such party to be filed on the basis of treating the Mergers as a reorganization within the meaning of Section 368(a)(1) of the Code unless otherwise required by a “determination” (within the meaning of Section 1313(a) of the Code).

1.9 Further Action. If, at any time after the Effective Time, any further action is determined by NetScout or the First Merger Surviving Entity or Second Merger Surviving Entity to be necessary or desirable to carry out the purposes of this Agreement or to vest the First Merger Surviving Entity or Second Merger Surviving Entity with full right, title and possession of and to all rights and property of Merger Sub and Newco, the officers and directors of the First Merger Surviving Entity or Second Merger Surviving Entity and NetScout shall be fully authorized (in the name of the Merger Subs, in the name of Newco and otherwise) to take such action.

1.10 Conversion of Shares in the Second Merger. Subject to the terms and conditions of this Agreement, at the Second Merger Effective Time, by virtue of the Second Merger and without any further action on the part of NetScout, the First Merger Surviving Entity, Merger Sub II or any stockholder of NetScout:

(a) each limited liability company interest of the First Merger Surviving Entity outstanding immediately prior to the Second Merger Effective Time shall be canceled and shall cease to exist and no consideration shall be delivered in exchange therefor; and

(b) each limited liability company interest in Merger Sub II outstanding immediately prior to the Second Merger Effective Time shall remain unchanged and continue to remain outstanding as a limited liability company interest in the Second Merger Surviving Entity.

(a) Promptly following the delivery of the Audited Financial Statements pursuant to Section 5.13, Danaher shall cause to be delivered to NetScout a statement setting forth a calculation of the Operating Profit derived from the audited financial statements of the Communications Business for the year ended December 31, 2013 included in the Audited Financial Statements (the “Operating Profit”).

(b) In the event that the Operating Profit is less than the amount set forth on Schedule 1.11(b), then Danaher shall pay to NetScout an amount equal to the product of (x) such shortfall multiplied by (y) 13.1; provided, however, that in no event shall such payment amount exceed $150,000,000 in cash. Such amount shall be paid to NetScout only in the event that the Closing occurs and shall be payable by wire transfer of same-day funds within three (3) business days after the Closing Date. The foregoing adjustment shall not impact NetScout’s rights to terminate this Agreement under Section 8 or its closing conditions under Section 6.

(c) Any payment made pursuant to this Section 1.11 is intended to be treated as a contribution by Danaher to Newco occurring immediately prior to the Closing Date.

As of the date of this Agreement, no material item of Newco IP is subject to any action or outstanding Order or settlement agreement or stipulation in litigation that restricts in any manner the use, provision, transfer, assignment or licensing thereof by Danaher or its Subsidiaries (including any Communications Company) or affects the validity, use, ownership, registrability or enforceability of such Newco IP. Except with regard to certain Danaher corporate names and marks set forth in Part 2.8(d) of the Danaher Disclosure Letter, no rights, title or interest in the names or other indicia of commercial source or origin used to designate any material Newco Products prior to Closing are owned by any Entity (including Danaher or its Subsidiaries) other than the Communications Companies.

5.2 NetScout Stockholders’ Meeting.

(a) As promptly as practicable following the date on which the SEC shall clear (whether orally or in writing) the Proxy Statement/Prospectus, NetScout: (i) shall take all action necessary under all applicable Legal Requirements to call, give notice of and hold a meeting of the holders of NetScout Common Stock (the “NetScout Stockholders’ Meeting”) to vote on a proposal to approve the issuance of shares of NetScout Common Stock pursuant to the First Merger pursuant to Nasdaq Listing Rule 5635 and (ii) shall submit such proposal to such holders at the NetScout Stockholders’ Meeting. NetScout shall not submit any other proposals for approval at the NetScout Stockholders’ Meeting without the prior written consent of Danaher. NetScout in consultation with Danaher shall set a record date for Persons entitled to notice of, and to vote at, the NetScout Stockholders’ Meeting and shall not change such record date without the prior written consent of Danaher (such consent not to be unreasonably withheld, conditioned or delayed). NetScout shall use its reasonable best efforts to ensure that all proxies solicited by the NetScout Companies and their Representatives in connection with the NetScout Stockholders’ Meeting are solicited in compliance with all applicable Legal Requirements. Notwithstanding anything to the contrary contained in this Agreement, NetScout may after consultation with Danaher adjourn or postpone the NetScout Stockholders’ Meeting: (i) to the extent necessary to ensure that any supplement or amendment to the Proxy Statement/Prospectus that is required by applicable Legal Requirement (or in connection with the settlement of any applicable litigation) is timely provided to NetScout’s stockholders; (ii) if as of the time for which the NetScout’s Meeting is originally scheduled there are insufficient shares of NetScout Common Stock represented (either in person or by proxy) to constitute a quorum necessary to conduct the business to be conducted at the NetScout Stockholders’ Meeting; or (iii) if additional time is reasonably required to solicit proxies in favor of the approval of the issuance of shares of NetScout Common Stock pursuant to the First Merger. Nothing contained in this Agreement shall be deemed to relieve NetScout of its obligation to submit the issuance of shares of NetScout Common Stock pursuant to the First Merger to its stockholders for a vote on the approval thereof. NetScout agrees that, unless this Agreement shall have been terminated in accordance with Section 8, its obligations to hold the NetScout Stockholders’ Meeting pursuant to this Section 5.2(a) shall not be affected by the commencement, public proposal, public disclosure or communication to NetScout of any Acquisition Proposal with respect to NetScout or Acquisition Inquiry with respect to NetScout or by any NetScout Change in Recommendation.

Merger at the NetScout Stockholders’ Meeting, (ii) the Proxy Statement/Prospectus shall include a statement to the effect that the NetScout Board recommends that NetScout’s stockholders vote to approve the issuance of shares of NetScout Common Stock pursuant to the First Merger at the NetScout Stockholders’ Meeting (such determination and recommendation being referred to as the “NetScout Board Recommendation”) and (iii) except as expressly permitted by Section 5.2(c), the NetScout Board Recommendation shall not be directly or indirectly withdrawn or modified (or proposed to be withdrawn or modified) by the NetScout Board nor any committee thereof in a manner adverse to Danaher (a “NetScout Change in Recommendation”).

(c) Notwithstanding anything to the contrary contained in Section 5.2(a) or elsewhere in this Agreement, at any time prior to the approval of the issuance of shares of NetScout Common Stock pursuant to the First Merger by the Required NetScout Stockholder Vote, the NetScout Board may effect, or cause NetScout to effect, as the case may be, a NetScout Change in Recommendation:

(i) if: (A) NetScout has not materially breached its obligations under Section 4.5; (B) after the date of this Agreement, an unsolicited, bona fide written Acquisition Proposal is made to NetScout and is not withdrawn; (C) the NetScout Board determines in its good faith judgment, after consulting with its financial advisor and outside legal counsel, that such Acquisition Proposal constitutes a NetScout Superior Offer; (D) the NetScout Board does not effect, or cause NetScout to effect, a NetScout Change in Recommendation at any time within four (4) business days (together with any subsequent shorter period as contemplated by clause (E) below, the “Notice Period”) after Danaher receives (x) written notice from NetScout that the NetScout Board has determined that such Acquisition Proposal is a NetScout Superior Offer and (y) a summary of the material terms and conditions of the Acquisition Proposal and other information required to be provided pursuant to Section 4.5 (provided, a new notice shall be required with respect to each material modification to such offer (it being understood that any change in the purchase price or form of consideration in such offer shall be deemed a material modification) and a new Notice Period (of three (3) business days) shall begin); (E) during the applicable Notice Period, if requested by Danaher, NetScout engages in good faith negotiations, and directs its financial advisors and outside legal advisors to, engage in good faith negotiations, with Danaher to amend this Agreement in such a manner that the competing Acquisition Proposal does not constitute a NetScout Superior Offer; (F) at the end of the applicable Notice Period, such Acquisition Proposal has not been withdrawn and constitutes a NetScout Superior Offer (taking into account any changes to the terms of this Agreement proposed by Danaher as a result of the negotiations required by clause “(E)” or otherwise); and (G) the NetScout Board determines in good faith, after having consulted with its outside legal counsel, that, in light of such NetScout Superior Offer, a failure to make a NetScout Change in Recommendation would be reasonably likely to constitute a breach of the fiduciary duties of the NetScout Board to NetScout stockholders under applicable Legal Requirements; or

(ii) if other than in connection with or as a result of the making of an Acquisition Proposal with respect to NetScout or an Acquisition Inquiry with respect to NetScout, a material development or change in circumstances that was not known or reasonably foreseeable (or if known or reasonably foreseeable, the probability or magnitude of consequences of which were not known or reasonably foreseeable) to the NetScout Board on the date of this Agreement occurs or arises after the date of this Agreement, which material development or change in circumstances becomes known to the NetScout Board prior to the approval of the issuance of shares of NetScout Common Stock pursuant to the First Merger by the Required NetScout Stockholder Vote (such material development or change in circumstances being referred to as an “Intervening Event” (it being understood that that in no event shall (i) any action taken by either party pursuant to and in compliance with the affirmative covenants set forth in Section 5.3, and the consequences of any such action or (ii) the receipt, existence of or terms of an Acquisition Proposal with respect to NetScout or an Acquisition Inquiry with respect to NetScout or the consequences thereof constitute an Intervening Event); (A) the NetScout Board determines in its good faith judgment,

A-44

##### Table of Contents

after consulting with its financial advisor and outside legal counsel that an Intervening Event has occurred; (B) the NetScout Board does not effect, or cause NetScout to effect, a NetScout Change in Recommendation at any time within four (4) business days after Danaher receives written notice from NetScout that the NetScout Board has determined that an Intervening Event requires the NetScout Board to effect, or cause NetScout to effect, a NetScout Change in Recommendation (provided, a new notice shall be required with respect to any change in circumstances and a new notice period of three (3) business days shall begin); (C) during such applicable period, if requested by Danaher, NetScout engages in good faith negotiations, and directs its financial advisors and outside legal advisors to, engage in good faith negotiations, with Danaher to amend this Agreement in such a manner that obviates the need for the NetScout Board to effect, or cause NetScout to effect, a NetScout Change in Recommendation as a result of such Intervening Event; and (D) the NetScout Board determines in good faith, after having consulted with its outside legal counsel, that, in light of such Intervening Event, a failure to make a NetScout Change in Recommendation would be reasonably likely to constitute a breach of the fiduciary duties of the NetScout Board to NetScout’s stockholders under applicable Legal Requirements.

(d) (i) Nothing contained in this Section 5.2 will prohibit NetScout from taking and disclosing to its stockholders a position required by Rule 14e-2(a) or Rule 14d-9 promulgated under the Exchange Act and (ii) no disclosure that the NetScout Board may determine in good faith (after consultation with outside counsel) that it or NetScout, as applicable, is required to make under applicable Legal Requirements will constitute a violation of this Agreement; provided, however, that in any event under clause (i) or (ii) the NetScout Board shall not make a NetScout Change in Recommendation except in accordance with this Section 5.2. It is expressly understood and agreed by the parties that a “stop, look and listen” or similar communication of the type contemplated by Rule 14d-9(f) of the Exchange Act shall not be deemed a NetScout Change in Recommendation; provided that the NetScout Board expressly reaffirms the NetScout Board Recommendation within five (5) business days of the public announcement of any applicable Acquisition Proposal.

5.3 Regulatory Approvals and Related Matters.

(a) Each party shall file all notices, reports and other documents required to be filed by such party with any Governmental Body with respect to the Mergers and the other Contemplated Transactions, and to submit promptly any additional information requested by any such Governmental Body.

NetScout and Danaher each shall use its reasonable best efforts to cause the expiration or early termination of any waiting period under the HSR Act, and NetScout and Danaher shall each (i) cooperate with the other party in connection with any filing or submission and in connection with any investigation or other inquiry, including any proceeding initiated by a private party, (ii) promptly supply the other party with any information which may be required in order to effectuate notices, reports, documents or other filings with any Governmental Body required to be made pursuant to the HSR Act and any applicable mandatory foreign competition act filings (the “Antitrust Filings”); and (iii) promptly supply any additional information which reasonably may be required by any Governmental Body in connection with Antitrust Filings or which the parties may reasonably deem appropriate. Each of NetScout and Danaher will notify the other party promptly upon the receipt of (and, if in writing, share a copy of) any communication received by such party from, or given by such party to, any Governmental Bodies and of any material communication received or given in connection with any proceeding by a private party, in each case in connection with the Contemplated Transactions. Whenever any event occurs that is required to be set forth in an amendment or supplement to any Antitrust Filings, NetScout or Danaher, as the case may be, will promptly inform the other party of such occurrence and cooperate in filing with the applicable Governmental Body (and share a copy of) such amendment or supplement. Each of NetScout and Danaher shall give the other party prompt notice of the commencement or known threat of commencement of any Legal Proceeding by or before any Governmental Body with respect to the Mergers or

Without limiting the generality of the foregoing, but subject to Section 5.3(b), each party to this Agreement agrees to use its reasonable best efforts to: (i) as promptly as practicable, prepare and file all filings (if any) and give all notices (if any) required to be made and given by such party in connection with the Mergers and the other Contemplated Transactions; (ii) obtain each Consent (if any) required to be obtained (pursuant to any applicable Legal Requirement or Contract, or otherwise) by such party in connection with the Mergers or any of the other Contemplated Transactions (including NetScout providing a guarantee of Newco’s obligations reasonable necessary to obtain such Consents); and (iii) lift any restraint, injunction or other legal bar to the Mergers.

(c) Notwithstanding anything to the contrary in this Section 5.3, neither NetScout, Danaher, Merger Sub nor Newco shall have any obligation under this Agreement (except as specifically set forth in this Agreement, the Distribution Agreement or any other Transaction Document) to divest or agree to divest (or cause any of its Subsidiaries to divest or agree to divest) any of its respective material businesses, material product lines or material assets, or to take or agree to take (or cause any of its Subsidiaries to take or agree to take) any other material action or agree (or cause any of its Subsidiaries to agree) to any material limitation or material restriction on any of its respective material businesses, material product lines or material assets, except as would not, or as would not reasonably be expected to, involve the divestiture of assets that generated in the aggregate more than 10% of the combined gross revenues of the Communications Companies and the NetScout Companies for the 12 months ending June 27, 2014 (a “Burdensome Condition”) (it being understood that no such action shall be considered for purposes of determining whether a NetScout Material Adverse Effect or Newco Material Adverse Effect has occurred or is reasonably likely to occur and the parties shall not be required to take any of the foregoing actions in this clause (c) unless the effectiveness of such action is conditioned on the Closing). Notwithstanding the foregoing, no such divestiture of assets may occur if such divestiture would constitute a Disqualifying Action (as defined in the Tax Matters Agreement).

(d) Each party shall not, and shall cause its Affiliates not to, acquire or agree to acquire any business or entity, or otherwise acquire or agree to acquire any assets, if doing so could reasonably be expected to delay or prevent consummation of the Contemplated Transactions, increase the risk of not obtaining any consents of any Governmental Body necessary to consummate the Contemplated Transactions or give rise to a requirement to obtain any additional Governmental Authorizations not currently required to consummate the Contemplated Transactions.

5.4 Disclosure. NetScout and Danaher shall consult with each other before issuing any press release or otherwise making any public statement regarding this Agreement or the Contemplated Transactions. Danaher shall consult with NetScout and consider the views and comments of NetScout before any of the Communications Companies or any of their Representatives sends any emails or other documents to the Newco Associates generally or otherwise communicate with the Newco Associates generally, with respect to the Mergers or any of the other Contemplated Transactions.

Danaher will use reasonable best efforts to procure, at its expense, the delivery of the consents of its independent accountants required to be filed with the NetScout Form S-4 Registration Statement or any future registration statement until such independent accountant consents are no longer required.

Communications Business. When delivered, such financial statements shall present fairly in all material respects the combined financial position and combined and consolidated results of operations of the Communications Business as of the dates and for the periods shown therein. Danaher acknowledges that NetScout’s ability to comply with its obligations under Section 5.1 depend, in part, on Danaher’s timely compliance with this Section 5.13, and therefore NetScout shall be afforded a reasonable period to comply with such obligations based upon the timing of Danaher providing the financial statements herein contemplated.

(c) In connection with the filing of the NetScout Form S-4 Registration Statement and other SEC filings, Danaher shall use its reasonable efforts during the Pre-Closing Period and after the Closing to (i) cooperate with NetScout to prepare pro forma financial statements that comply with the rules and regulations of the SEC to the extent required for SEC filings, including the requirements of Regulation S-X and (ii) provide and make reasonably available upon reasonable notice the senior management employees of Danaher to discuss the materials prepared and delivered pursuant to this Section 5.13(c).

Danaher and the Communications Companies shall, and shall cause their respective Representatives to, use commercially reasonable efforts to provide such cooperation (including with respect to timeliness) to NetScout, at NetScout’s sole expense, in connection with the arrangement of the Debt Financing as may be reasonably requested by NetScout, including by using commercially reasonable efforts in providing to NetScout and its Debt Financing Sources from time to time information regarding the Communications Companies reasonably requested by the lenders providing the Debt Financing (it being understood that such information shall not be required to be of a level of detail greater than the information made available by Danaher to NetScout in the virtual data room maintained by Danaher on the Data Site from Merrill Corporation); provided that, in all cases, such activities do not interfere with or disrupt the operation and management of the Communications Business; provided, however, that, irrespective of the above, no obligation of Danaher or its Subsidiaries (including the Communications Companies) under any certificate, document or instrument shall be effective until the Effective Time (except for customary pre-filing of UCC financing statements) and none of Danaher or its Subsidiaries (including the Communications Companies) shall be required to take any action (A) under any certificate, document or instrument that is not contingent upon the Closing (including the entry into any agreement that is effective before the Effective Time) or that would be effective prior to the Effective Time (except, in any such case, for customary pre-filing of UCC financing statements) or (B) that would reasonably be expected to cause any director, officer or employee of Danaher or its Subsidiaries (including the Communications Companies) to incur any personal liability. For the avoidance of doubt, none of the Danaher or the Communications Companies shall be required to pay any commitment or other similar fee in connection with, or incur any other expenses or costs associated with NetScout’s arrangement of the Debt Financing. NetScout shall, promptly upon request by the Danaher, reimburse Danaher for all documented and reasonable out-of-pocket costs incurred by Danaher or its Subsidiaries (including the Communications Companies) in connection with this Section 5.14. NetScout shall indemnify and hold harmless Danaher and its Subsidiaries (including the Communications Companies) and their respective Representatives from and against any and all liabilities, losses, damages, claims, costs, reasonable expenses, interest, awards, judgments and penalties suffered or incurred in connection with the arrangement of the Debt Financing (including any action taken in accordance with this Section 5.14) and any information utilized in connection therewith (other than information relating to Danaher and its Subsidiaries (including the Communications Companies) provided by Danaher in writing specifically for use in the Debt Financing offering documents); provided, however, that NetScout shall not be obligated to indemnify and hold harmless Danaher and its Subsidiaries (including the Communications Companies) and their respective Representatives pursuant to this sentence the extent any such otherwise indemnifiable proximately resulted from the willful misconduct, gross negligence or fraud of Danaher and its Subsidiaries (including the Communications Companies). Further, and for avoidance of doubt, NetScout’s obligations to effect the Contemplated Transactions shall not be subject to its ability to obtain Debt Financing, or any alternative financing, nor shall they be subject to any form of financing contingency.

(a) Danaher shall assign, transfer, convey and deliver (“Convey”) (and shall cause any applicable Subsidiary to Convey) to Newco or one or more Newco Subs in accordance with the Plan of Reorganization (as defined below) and the other terms and conditions of this Agreement, and Newco shall accept from Danaher, and shall cause the applicable Newco Sub to accept, the Communications Assets and all of Danaher’s and its applicable Subsidiaries’ respective direct or indirect right, title and interest in, to and under all Communications Assets (other than any Communications Assets that are already held as of the Separation Time by Newco or a Newco Sub, which Communications Assets shall continue to be held by Newco or such Newco Sub after the Separation Time), free and clear of all Security Interests (other than Permitted Encumbrances). The preliminary plan and structure set forth on Schedule 1.01(a) as of the date hereof is referred to herein as the “Preliminary Plan”, and the corporate structuring steps contemplated by the Plan of Reorganization as finally determined in accordance with Section 1.01(a) being referred to herein as the “Internal Restructuring”. Except as otherwise expressly set forth herein, the Preliminary Plan may be amended, modified or supplemented in the sole discretion of Danaher until such time as the Preliminary Plan becomes the Plan of Reorganization in accordance with Section 1.01(b).

(b) As promptly as practicable following the date of this Agreement (but in no event later than January 15, 2015), Danaher shall deliver to NetScout an updated version of the Preliminary Plan for NetScout’s review and approval, such approval not to be unreasonably withheld, conditioned or delayed, setting forth Danaher’s plan (with reasonable specificity on the corporate transaction steps) with respect to the Internal Restructuring necessary: (i) to allocate and Convey to Newco (or the applicable Newco Sub) the Communications Assets, the Communications Liabilities and ownership of the Newco Subs to reach the Newco structure as it will exist as of immediately prior to the Distribution; and (ii) to identify any material Government Approvals required in connection with the Internal Restructuring (such plan as finally delivered and accepted in accordance with this Section 1.01(b), the “Plan of Reorganization”), provided, however, that NetScout’s approval shall be deemed granted for purposes of this sentence and the immediately following sentence in the event that no detailed written proposed revisions are received by Danaher from NetScout within five (5) Business Days. Once the Plan of Reorganization has been delivered and accepted hereunder, such Plan of Reorganization may only be further amended, modified or supplemented by Danaher with the express written consent of NetScout, such consent not to be unreasonably withheld, conditioned or delayed.

(c) Danaher shall: (i) provide NetScout with an opportunity to review any contemplated amendments, modifications or supplements to the Preliminary Plan; (ii) consult with NetScout in good faith regarding any such amendments, modifications or supplements and consider in good faith any comments received from NetScout in connection therewith; and (iii) promptly provide NetScout with copies of any such amendments, modifications or supplements.

Plan of Reorganization, and Newco shall assume, perform, satisfy, discharge and fulfill when due and, to the extent applicable, comply with on a timely basis, or shall cause any applicable Newco Sub to assume, perform, satisfy, discharge and fulfill when due and, to the extent applicable, comply with on a timely basis, all of the Communications Liabilities, in accordance with their respective terms (other than any Communications Liabilities that as of the Separation Time are already Liabilities of Newco or a Newco Sub, which Communications Liabilities shall continue to be Liabilities of Newco or such Newco Sub after the Separation Time). As between members of the Danaher Group, on the one hand, and members of the Newco Group, on the other hand, following the Separation Time, the members of the Newco Group will be solely responsible for all Communications Liabilities, on a joint and several basis.

Section 1.03 Transfer of Excluded Assets; Excluded Liabilities. Subject to Section 1.08(b), prior to the Separation Time: (i) Danaher shall cause any applicable Newco Sub to Convey to Danaher or an appropriately capitalized Subsidiary of Danaher (as Danaher may designate) (other than any member of the Newco Group) any Excluded Assets that it owns, leases or has any right to use, and Danaher shall accept from such Newco Sub, or shall cause any designated Subsidiary of Danaher (other than any member of the Newco Group) to accept, the Excluded Assets and all such respective right, title and interest in and to any and all of such Excluded Assets; and (ii) Danaher shall cause any applicable Newco Sub to Convey any Excluded Liability for which it is otherwise responsible to Danaher or an appropriately capitalized Subsidiary of Danaher (as Danaher may designate) (other than any member of the Newco Group), and Danaher shall assume, perform, satisfy, discharge and fulfill when due, and to the extent applicable, comply with on a timely basis, or shall cause the designated Subsidiary of Danaher to assume, perform, satisfy, discharge and fulfill when due, and to the extent applicable, comply with on a timely basis, any and all of such Excluded Liabilities in accordance with their respective terms. As between members of the Danaher Group, on the one hand, and members of the Newco Group, on the other hand, following the Separation Time, the members of the Danaher Group will be solely responsible for all Excluded Liabilities, on a joint and several basis.

Section 1.04 Misallocated Transfers. In the event that, at any time from and after the Separation Time, either Danaher or Newco (or any member of the Danaher Group or the Newco Group, as applicable) discovers that it or one of its Affiliates is the owner of, receives or otherwise comes to possess or benefit from any Asset (including the receipt of payments made pursuant to Contracts and proceeds from accounts receivable with respect to such Asset) or is liable for any Liability that is otherwise allocated to any Person that is a member of the other Group pursuant to this Agreement or any Ancillary Agreement (except in the case of any deliberate acquisition of Assets or assumption of Liabilities from the other Party for value subsequent to the Separation Time), such Party shall promptly Convey, or cause to be Conveyed, such Asset or Liability to the Person so entitled thereto (and the relevant Party shall cause such entitled Person to accept such Asset or assume such Liability) for no consideration. Prior to any such transfer, such Asset shall be held in accordance with Section 1.08(b). For the avoidance of doubt, if any cash or cash equivalents remain in Newco (or any member of the Newco Group) immediately following the Separation Time, Newco shall promptly Convey, or cause to be Conveyed, such amount of cash and cash equivalents (including any interest earned thereon) to Danaher or its designee(s).

##### Table of Contents

(b) The provisions of Section 1.07(a) shall not apply to any of the following Contracts (or to any of the provisions thereof):

(ii) any Contracts or Intercompany Accounts solely between or among members of the Newco Group;

(iii) any Contracts to which any Person, other than the Parties and their respective Affiliates, is a Party;

(iv) any Contracts between: (i) a Subsidiary of Danaher that is in the business of selling or buying products or services to or from third parties; and (ii) a member of the Newco Group, and which Contract is related primarily to the provision of such products or services and was or is entered into in the ordinary course of business and on arms’-length terms; and

For the avoidance of any doubt, any and all Liabilities arising from the activities contemplated by this Section 1.07 will constitute Excluded Liabilities for the purposes hereof.

Section 1.08 Third-Party Consents.

(a) Obtaining Consents; Consent Committee. The Parties shall, as promptly as practicable after the date hereof and for a period of eighteen (18) months following the Closing, cooperate with each other and use their respective reasonable best efforts to obtain: (i) the transfer, assignment or reissuance to Newco or a member of the Newco Group of all Transferable Permits; and (ii) all Consents and Governmental Approvals of all other Persons to the extent necessary to consummate the Newco Transfer as required by the terms of any Law, license, permit, concession or Contract to which Danaher or any of its Subsidiaries is currently a party or by which any of them is bound, subject to the limitations set forth in this Section 1.08; provided, however, that no Party or member of the Danaher Group shall be required to make any material payments, incur any material Liability or offer or grant any material accommodation (financial or otherwise, that is not provided for in the underlying Contract) (it being understood that materiality shall, in the case of Danaher or its Subsidiaries, be measured in relation to the Communications Business) to any third party to obtain any such Consents; provided, further, that Danaher and NetScout shall each be responsible for 50% of the costs associated with obtaining such consents. Each of the Parties agrees that it shall not commit, and shall cause its Subsidiaries not to commit, to any third party on behalf of Newco or any member of the Newco Group to make any payments, incur any Liability or offer or grant any accommodation (financial or otherwise, regardless of any provision to the contrary in the underlying Contract, including any requirements for the securing or posting of any bonds, letters of credit or similar instruments, or the furnishing of any guarantees) to any third party to obtain any such Consents that would be a Liability of Newco or any member of the Newco Group after the Separation Time, without Newco’s prior express written consent (and, unless the Merger Agreement shall have been terminated in accordance with its terms, NetScout’s prior express written consent). For the avoidance of doubt, the required efforts and responsibilities of the Parties to seek the regulatory approvals contemplated by the Antitrust Filings (as defined in

B-9

##### Table of Contents

the Merger Agreement) shall be governed by the Merger Agreement. Promptly following the date hereof (and in any case within thirty (30) days after the date hereof), the Parties shall establish a committee (the “Consent Committee”), composed of at least one (1) manager-level employee of each of Danaher and NetScout, which shall be responsible for coordinating and helping to implement the provisions of this Section 1.07(a) (including discussing and agreeing on action plans to resolve any outstanding obligations under this Section 1.08(a)) for a period of time starting on the date hereof and ending eighteen (18) months following the Closing Date. The Consent Committee shall meet telephonically or in person on a monthly basis. The Consent Committee process described in this Section 1.08(a) shall be subject to modification or termination upon mutual consent of Danaher and NetScout.

(b) Transfer in Violation of Laws or Requiring Consent or Governmental Approval. If and to the extent that the Conveyance to any member of the Newco Group of any Communications Assets or to any member of the Danaher Group of any Excluded Assets would be a violation of applicable Laws or require any Consent or Governmental Approval in connection with the Newco Transfer that has not been obtained at the Separation Time, then, notwithstanding any other provision hereof, the Conveyance to the Newco Group of such Communications Assets or to the Danaher Group of such Excluded Assets (any such Asset, a “Deferred Asset”) shall automatically be deferred and no Conveyance shall occur until all legal impediments are removed or such Consents or Governmental Approvals have been obtained. Notwithstanding the foregoing, any such Deferred Asset shall still be considered a Communications Asset or Excluded Asset, as applicable, and the Person retaining such Asset shall thereafter hold such Asset in trust for the benefit of the Person entitled thereto (and at such Person’s sole expense) until the consummation of the Conveyance thereof. To the extent that any Deferred Asset cannot be Conveyed without the Consent or Governmental Approval of any Person which Consent or Governmental Approval has not been obtained prior to the Separation Time, this Agreement will not constitute an agreement to Convey the same if an attempted Conveyance would constitute a breach thereof or violate any Law. The Parties shall use their reasonable best efforts to develop and implement mutually acceptable arrangements to place the Person entitled to receive such Deferred Asset, insofar as reasonably possible, in the same position as if such Deferred Asset had been Conveyed as contemplated hereby and so that all the benefits and burdens relating to such Deferred Asset, including possession, use, risk of loss, potential for gain, any Tax Liabilities in respect thereof and dominion, ability to enforce the rights under or with respect to, control and command over such Deferred Asset, are to inure from and after the Separation Time. Such arrangements may include, among others, the entry into reseller agreements with respect to government Contracts, or the entry into subcontracting agreements. If and when the legal or contractual impediments the presence of which caused the deferral of transfer of any Deferred Asset pursuant to this Section 1.08(b) are removed or any Consents and/or Governmental Approvals the absence of which caused the deferral of transfer of any Deferred Asset pursuant to this Section 1.08(b) are obtained, the transfer of the applicable Deferred Asset shall be effected in accordance with the terms of this Agreement and/or such applicable Ancillary Agreement. The obligations set forth in this Section 1.08(b) shall survive for the duration of the term of the applicable Contract (without any obligation to renew or extend).

(c) Shared Contracts.

(i) Danaher (including on behalf of the other members of the Danaher Group) shall use reasonable best efforts to separate and cause the applicable member of the Newco Group to enter into new agreements with the counterparties to the Danaher Shared Contracts prior to the Separation. Upon such separation of a Danaher Shared Contract, the separated Contract that is related to the Communications Business will be a Newco Contract and the other separated Contract will be an Excluded Asset. To the extent that Danaher is unable or the counterparties are unwilling to enter into agreements with respect to any Danaher Shared Contract, Danaher (or the applicable member of the Danaher Group) will partially assign the Communications Business functions to Newco in the manner agreed to by the Parties (but only if such Danaher Shared Contract is assignable) and in the event that such partial assignment is not permitted by the terms of the applicable Danaher Shared Contract or consented to by the applicable counterparty, Danaher shall use reasonable best efforts to provide for an alternative arrangement so that the applicable member of the Newco Group will have the benefits of such

Danaher Shared Contract as though it had been partially assigned; provided, however, that no member of the Danaher Group shall be required to make any payments (other than as provided for in the underlying Contract) to any third party in connection with the foregoing; provided, further, that Danaher shall obtain Newco’s express written consent prior to agreeing to any waiver, amendment, modification or termination under any such Danaher Shared Contract if such waiver, amendment, modification would have the effect of limiting, restricting or increasing the costs to a member of the Newco Group’s rights or interests under such Danaher Shared Contract in a materially disproportionate manner relative to Danaher’s other businesses covered under such Danaher Shared Contract. Newco shall cooperate with Danaher in connection with the entering into of any new agreement or partial assignment. The obligations set forth in the first sentence of this Section 1.08(c)(i) regarding Danaher use of reasonable best efforts to separate and assign Danaher Shared Contracts shall terminate on the eighteen (18) month anniversary of the Closing Date, and the obligations set forth in the remainder of this Section 1.08(c)(i), including the obligations of Danaher to use reasonable best efforts to provide for alternative arrangements, shall survive for the duration of the term of the applicable Contract (without any obligation to renew or extend).

(ii) Newco (including on behalf of the other members of the Newco Group) shall use reasonable best efforts to separate and cause the applicable member of the Danaher Group to enter into new agreements with the counterparties to the Newco Shared Contracts prior to the Separation. Upon such separation of a Newco Shared Contract, the separated Contract that is related to the Communications Business will be a Newco Contract and the other separated Contract will be an Excluded Asset. To the extent that Newco is unable or the counterparties are unwilling to enter into agreements with respect to any Newco Shared Contract, Newco (or the applicable member of the Newco Group) will partially assign the non-Communications Business functions to Danaher in the manner agreed to by the Parties (but only if such Newco Shared Contract is assignable) and in the event that such partial assignment is not permitted by the terms of the applicable Newco Shared Contract or consented to by the applicable counterparty, Newco shall use reasonable best efforts to provide for an alternative arrangement so that the applicable member of the Danaher Group will have the benefits of such Newco Shared Contract as though it had been partially assigned; provided, however, that no member of the Newco Group shall be required to make any payments (other than as provided for in the underlying Contract) to any third party in connection with the foregoing; provided, further, that Newco shall obtain National’s written consent prior to agreeing to any waiver, amendment, modification or termination under any such Newco Shared Contract if such waiver, amendment, modification or termination would have the effect of limiting, restricting or increasing the costs of a member of the Danaher Group’s rights or interests under such Newco Shared Contract. Danaher shall cooperate with Newco in connection with the entering into of any new agreement or partial assignment. The obligations set forth in the first sentence of this Section 1.08(c)(ii) regarding Newco’s use of reasonable best efforts to separate and assign Newco Shared Contracts shall terminate on the eighteen (18) month anniversary of the Closing Date, and the obligations set forth in the remainder of this Section 1.08(c)(ii), including the obligations of Newco to use reasonable best efforts to provide for alternative arrangements, shall survive for the duration of the term of the applicable Contract (without any obligation to renew or extend).

Section 1.09 Novations of Newco Contracts. Upon Danaher’s request, the Parties (which, prior to the Effective Time shall not impose obligations on NetScout under any Newco Contract) shall use reasonable best efforts to obtain the novation of any Newco Contract so specified by Danaher, whether prior to, at or following the Separation Time (it being understood that such obligations shall apply following the Separation Time regardless of whether any such Newco Contract has been Conveyed pursuant to the terms hereof or such Conveyance was deferred in accordance with Section 1.08(b)); provided, however, that no member of the Danaher Group shall be required to make any payments (other than as provided for in the underlying Contract) to any third party in connection with the foregoing. The foregoing obligations shall terminate on the eighteen (18) month anniversary of the Closing Date.

COMPLETION OF THE DISTRIBUTION

Section 3.01 Manner of Distribution. Danaher may, in its sole discretion, elect to effect the Distribution as a Spin-Off, as an Exchange Offer, or as a combination of a Spin-Off and an Exchange Offer with or without a Clean-Up Spin-Off and shall advise NetScout of the form of the Distribution no later than thirty (30) Business Days prior to the anticipated Closing Date. Danaher will provide notice (with a copy to NetScout) to the Financial Industry Regulatory Authority (“FINRA”) no later than ten (10) days prior to the Record Date (as determined in accordance with Section 3.02(a)) in compliance with Rule 10b-17 under the Exchange Act. All Newco Common Units held by Danaher on the Distribution Date will be distributed to the Record Holders in the manner set forth in Section 3.02(a) and in accordance with Section 3.04(b). At least five (5) days prior to the Distribution Date, Danaher shall provide to Newco and NetScout a list of Record Holders entitled to receive Newco Common Units in connection with the Distribution.

Section 3.02 The Distribution.

(a) To the extent the Distribution includes a Spin-Off, subject to the terms thereof, in accordance with Section 3.02(c), each Record Holder will be entitled to receive for each share of common stock, par value $0.01 per share (“Danaher Common Stock”), of Danaher held by such Record Holder as of the Record Date a number of Newco Common Units equal to the total number of Newco Common Units held by Danaher on the Distribution Date, multiplied by a fraction, the numerator of which is the number of Danaher Common Stock held by such Record Holder as of the Record Date and the denominator of which is the total amount of Danaher Common Stock outstanding on the Record Date. To the extent the Distribution is effected as a Spin-Off, prior to the Distribution Date, the Danaher Board, in accordance with applicable Law, shall establish (or designate a committee of the Danaher Board to establish) the Record Date for the Distribution and any appropriate procedures in connection with the Spin- Off. To the extent any of the Distribution is effected as an Exchange Offer followed by a Clean-Up Spin-Off of any remaining Newco Common Units to be distributed by Danaher pursuant to Section 3.02(b), the Danaher Board shall set the Record Date as the time on the Distribution Date immediately following the time at which the validly tendered shares of Danaher Common Stock are accepted for payment in the Exchange Offer.

(b) Subject to the terms and conditions thereof, to the extent any of the Distribution is effected as an Exchange Offer, each Danaher shareholder may elect in the Exchange Offer to exchange a number of shares of Danaher Common Stock held by such Danaher stockholder for Newco Common Units. Subject to applicable

securities Laws, Danaher shall determine, in its sole discretion, the terms and conditions of the Exchange Offer, including the exchange ratio (including any discount to the reference price of common stock of NetScout), the timing of the offer period and any extensions thereto, and other customary provisions, each as will be set forth in the Newco Registration Statement (as defined below) and Schedule TO; provided, however, that the maximum number of days that the Exchange Offer may be extended following satisfaction of the conditions to Closing set forth in Article VI and Article VII of the Merger Agreement (other than consummation of the transactions contemplated by this Agreement and satisfaction of those conditions to be satisfied as of the Closing Date) shall be ten (10) Business Days. Before filing the Newco Registration Statement, the Schedule TO or any amendments or supplements thereto, or comparable documents under securities or state “blue sky” laws of any jurisdiction, Danaher and/or Newco (as applicable) will furnish to NetScout and its counsel copies of all such documents proposed to be filed (including all exhibits thereto), which documents will be subject to the reasonable comment of NetScout and its counsel, and, before filing any such document, Danaher and/or Newco (as applicable) shall reasonably consider any changes thereto that NetScout and its counsel shall reasonably request.

(c) The terms and conditions of any Clean-Up Spin-Off shall be as determined by Danaher in its sole discretion; provided, however, that: (i) any Newco Common Units that are not subscribed for in the Exchange Offer must be distributed to Danaher’s shareholders in the Clean-Up Spin-Off; and (ii) subject to any applicable Law or stock exchange requirement, the Clean-Up Spin-Off shall take place on the Distribution Date immediately following the consummation of the Exchange Offer and the Record Date for the Clean-Up Spin-Off shall be established as of such date in the same manner as provided in Section 3.02(a).

(d) No action by any Record Holder shall be necessary for such Record Holder (or such Record Holder’s designated transferee or transferees) to receive the applicable number of Newco Common Units such stockholder is entitled to in the Distribution. For stockholders of Danaher who own Danaher Common Stock through a broker or other nominee, their Newco Common Units will be credited to their respective accounts by such broker or nominee.

(e) Upon the consummation of the Distribution, Danaher shall deliver to the Exchange Agent a global certificate representing the Newco Common Units being transferred in the Distribution, for the account of Danaher’s stockholders that are entitled thereto. The Exchange Agent shall hold such certificate or certificates, as the case may be, for the account of Danaher’s stockholders pending the Mergers. In no event shall the number of Newco Common Units issued and distributed in the Distribution exceed the number of Newco Common Units determined pursuant to Section 3.02(a), as adjusted if necessary pursuant to Section 3.02(d).

(f) The Parties shall keep each other reasonably informed with respect to the transactions contemplated by this Section 3.02 in order to coordinate the timing of such transactions to the extent reasonably practicable and desirable and otherwise consistent with the other provisions of this Section 3.02.

(g) Neither of the Parties, and none of their respective Affiliates, will be liable to any Person in respect of any Newco Common Units (or dividends or distributions with respect thereto) that are properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

Section 3.03 Actions Prior to Distribution.

(a) Newco will cooperate with Danaher to accomplish the Distribution, including in connection with the preparation of all documents and the making of all filings required in connection with the Distribution.

(c) Danaher and Newco will take all such action as may be necessary or appropriate under the securities or blue sky laws of the United States (and any comparable Laws under any foreign jurisdiction) in connection with the Distribution.

(d) Danaher and Newco will take all reasonable steps necessary and appropriate to cause the conditions set forth in Section 7.02 to be satisfied and to effect the Distribution on the Distribution Date.

(e) Notwithstanding anything to the contrary, any and all costs, expenses and Liabilities incurred by or on behalf of Newco or any member of the Newco Group as a result of or in connection with the matters set forth in this Section 3.03 shall be the sole responsibility of Danaher and shall be deemed to be “Excluded Liabilities” for the purposes hereof.

(f) Notwithstanding anything to the contrary, without any further action required by any Party, effective as of immediately prior to the Effective Time, all provisions of this Section 3.03, with the exception of Section 3.03(a), shall automatically terminate and be of no further force and the Parties shall cease to have any rights or obligations thereunder.

The Exchange Agent will hold such certificate or certificates, as the case may be, for the account of the Danaher stockholders pending the First Merger, as provided in Section 1.6 of the Merger Agreement.

(d) any breach of the representations and warranties set forth in the first sentence of Section 2.6(a), Section 2.6(b), the first sentence of Section 2.8(d) and Section 2.8(g) of the Merger Agreement (determined, in each case, for all purposes without regard to any material, materiality, Material Adverse Effect or other similar qualification contained therein).

Section 4.04 Survival. No claim or cause of action for indemnification under Section 4.03(d) may be made following the termination of the applicable survival period set forth in Section 9.3 of the Merger Agreement; it being understood that in the event notice of any claim for indemnification under Section 4.03(d) shall have been given within the applicable survival period set forth in Section 9.3 of the Merger Agreement, the representations and warranties that are the subject of such indemnification claim shall survive until such time as such claim is finally resolved.

Section 4.05 Basket and Cap. Danaher’s obligation to indemnify Newco Indemnitees for Losses pursuant to Section 4.03(d) is subject to the limitation that no indemnification shall be made by Danaher with respect to any claim (including any Losses) until the aggregate amount of all such Losses for which indemnification may be sought hereunder exceeds $5,000,000 (the “Deductible”), at which point the Newco Indemnitees shall be entitled to indemnification only for those Losses in excess of the Deductible; provided, however, that only individual claims or series of related claims involving Losses in excess of $100,000 shall be included in the Deductible or be counted for determining the amount of Losses to be indemnified to the Newco Indemnitees. Notwithstanding the foregoing, in no event shall the obligation of Danaher to indemnify Newco Indemnitees pursuant to Section 4.03(d) exceed, in the aggregate, $250,000,000. For the avoidance of doubt, the limitations in this Section 4.05 shall not apply to any claims for indemnification pursuant to Section 4.03(a)-(c). For the avoidance of doubt, nothing herein shall limit the ability of Danaher to Convey Communications Assets to NetScout or Newco in respect of any alleged breach of the first sentence of Section 2.6(a), Section 2.6(b), the first sentence of Section 2.8(d) or Section 2.8(g) of the Merger Agreement.

Section 4.06 Procedures for Indemnification.

(a) An Indemnitee shall give the Indemnifying Party notice of any matter that an Indemnitee has determined has given or would reasonably be expected to give rise to a right of indemnification under this Agreement (other than a Third-Party Claim, which shall be governed by Section 4.07(b)), within twenty (20) Business Days of such determination, stating the amount of the Loss claimed, if known, and method of computation thereof, and containing a reference to the provisions of this Agreement in respect of which such

B-19

##### Table of Contents

right of indemnification is claimed by such Indemnitee or arises; provided, however, that the failure to provide such notice shall not release the Indemnifying Party from any of its obligations except and solely to the extent the Indemnifying Party shall have been materially prejudiced as a result of such failure.

(b) If a claim or demand is made against a Danaher Indemnitee or a Newco Indemnitee (each, an “Indemnitee”) by any Person who is not a party to this Agreement or an Affiliate of a Party (a “Third-Party Claim”) as to which such Indemnitee is or reasonably expects to be entitled to indemnification pursuant to this Agreement, such Indemnitee shall notify the Party that is or may be required pursuant to this Article IV or pursuant to any Ancillary Agreement to make such indemnification (the “Indemnifying Party”) in writing, and in reasonable detail, of the Third-Party Claim promptly (and in any event within thirty (30) calendar days) after receipt by such Indemnitee of written notice of the Third-Party Claim; provided, however, that the failure to provide notice of any such Third-Party Claim pursuant to this sentence shall not release the Indemnifying Party from any of its obligations except and solely to the extent the Indemnifying Party shall have been materially prejudiced as a result of such failure (except that the Indemnifying Party or Parties shall not be liable for any expenses incurred by the Indemnitee in defending such Third-Party Claim during the period in which the Indemnitee failed to give such notice). Thereafter, the Indemnitee shall deliver to the Indemnifying Party, promptly (and in any event within ten (10) Business Days) after the Indemnitee’s receipt thereof, copies of all notices and documents (including court papers) received by the Indemnitee relating to the Third-Party Claim.

(c) Other than in the case of any Liability being managed by a Party in accordance with any Ancillary Agreement or as provided in Section 4.08(a), an Indemnifying Party shall be entitled (but shall not be required) to assume, control the defense of, and settle any Third-Party Claim, at such Indemnifying Party’s own cost and expense and by such Indemnifying Party’s own counsel, which counsel must be reasonably acceptable to the applicable Indemnitees, if it gives written notice of its intention to do so and agreement that the Indemnitee is entitled to indemnification under this Article IV to the applicable Indemnitees within thirty (30) calendar days of the receipt of notice from such Indemnitees of the Third-Party Claim. After such notice from an Indemnifying Party to an Indemnitee of its election to assume the defense of a Third-Party Claim, such Indemnitee shall have the right to employ separate counsel and to participate in (but not control) the defense, compromise or settlement thereof, at its own expense and, in any event, shall reasonably cooperate with the Indemnifying Party in such defense and make available to the Indemnifying Party all witnesses, pertinent and material Information and materials in such Indemnitee’s possession or under such Indemnitee’s control relating thereto as are reasonably required by the Indemnifying Party; provided, however, that such access shall not require the Indemnitee to disclose any information the disclosure of which would, in the reasonable judgment of the Indemnitee, result in the loss of any existing attorney-client privilege with respect to such information or violate any applicable Law.

(d) Notwithstanding anything to the contrary in this Section 4.06, in the event that: (i) an Indemnifying Party elects not to assume responsibility for defending a Third-Party Claim; (ii) there exists a conflict of interest or potential conflict of interest between the Indemnifying Party and the applicable Indemnitee(s), (iii) any Third-Party Claim seeks an order, injunction or other equitable relief or relief for other than money damages against the Indemnitee; (iv) the Indemnifying Party shall not have employed counsel to represent the Indemnitee within thirty (30) calendar days after notice from the Indemnitee of such Third-Party Claim; or (v) the party making such Third-Party Claim is a Governmental Authority with regulatory authority over the Indemnitee or any of its material Assets, such Indemnitee(s) shall be entitled to assume the defense of such Third-Party Claim, at the Indemnifying Party’s expense, with counsel of such Indemnitee’s choosing. If the Indemnitee is conducting the defense against any such Third-Party Claim, the Indemnifying Party shall reasonably cooperate with the Indemnitee in such defense and make available to the Indemnitee all witnesses, pertinent and material Information and materials in such Indemnifying Party’s possession or under such Indemnifying Party’s control relating thereto as are reasonably required by the Indemnitee pursuant to a joint defense agreement to be entered into by Indemnitee and the Indemnifying Party; provided, however, that such access shall not require the Indemnifying Party to disclose any information the disclosure of which would, in the reasonable judgment of the Indemnifying Party, result in the loss of any existing attorney-client privilege with respect to such information or violate any applicable Law.

(e) No Indemnitee may settle or compromise any Third-Party Claim without the consent of the Indemnifying Party, which consent shall not be unreasonably withheld, conditioned or delayed. If an Indemnifying Party has failed to assume the defense of the Third-Party Claim, it shall not be a defense to any obligation to pay any amount in respect of such Third-Party Claim that the Indemnifying Party was not consulted in the defense thereof, that such Indemnifying Party’s views or opinions as to the conduct of such defense were not accepted or adopted, that such Indemnifying Party does not approve of the quality or manner of the defense thereof or that such Third-Party Claim was incurred by reason of a settlement rather than by a judgment or other determination of liability.

(f) In the case of a Third-Party Claim, no Indemnifying Party shall consent to entry of any judgment or enter into any settlement of the Third-Party Claim without the consent (not to be unreasonably withheld, conditioned or delayed) of the Indemnitee if the effect thereof is to permit any injunction, declaratory judgment, other order or other non-monetary relief to be entered, directly or indirectly, against any Indemnitee, or does not release the Indemnitee from all liabilities and obligations with respect to such Third-Party Claim or includes an admission of guilt or liability on behalf of the Indemnitee.

(g) Except as otherwise provided in Section 9.04, the Merger Agreement or any Ancillary Agreement, following the Closing, the indemnification provisions of this Article IV shall be the sole and exclusive remedy of an Indemnitee for any monetary or compensatory damages or Losses resulting from any breach of this Agreement (including with respect to monetary or compensatory damages or Losses arising out of or relating to, as the case may be, any Communications Liability or Excluded Liability), and each Indemnitee expressly waives and relinquishes any and all rights, claims or remedies such Person may have with respect to the foregoing other than under this Article IV against any Indemnifying Party.

Section 4.07 Indemnification Obligations Net of Proceeds Received from Third Parties.

(a) Any Liability subject to indemnification or contribution pursuant to this Article IV will be net of any proceeds received by the Indemnitee from any third party (net of any deductible or retention amount or any other third-party costs or expenses incurred by the Indemnifying Party in obtaining such recovery, including any increased insurance premiums) for indemnification for such Liability that actually reduce the amount of the Liability (“Third-Party Proceeds”). Accordingly, the amount which any Indemnifying Party is required to pay pursuant to this Article IV to any Indemnitee pursuant to this Article IV will be reduced by Third-Party Proceeds theretofore actually recovered by or on behalf of the Indemnitee in respect of the related Liability. If an Indemnitee receives a payment required by this Agreement from an Indemnifying Party in respect of any Liability (an “Indemnity Payment”) and subsequently receives Third-Party Proceeds, then the Indemnitee will pay to the Indemnifying Party an amount equal to the excess of the Indemnity Payment received over the amount of the Indemnity Payment that would have been due if the Third-Party Proceeds had been received, realized or recovered before the Indemnity Payment was made.

(b) The Indemnitee shall use commercially reasonable efforts to seek to collect or recover any Third-Party Proceeds to which the Indemnitee is entitled in connection with any Liability for which the Indemnitee seeks contribution or indemnification pursuant to this Article IV; provided, however, that the Indemnitee’s inability to collect or recover any such Third-Party Proceeds shall not limit the Indemnifying Party’s obligations hereunder.

Section 4.08 Certain Actions; Substitution; Subrogation.

(a) Certain Actions. Notwithstanding anything to the contrary set forth in Section 4.06, and subject to the provisions of the Tax Matters Agreement and the Employee Matters Agreement, which shall remain exclusive as to Tax matters and employee and benefit matters, respectively, and except to the extent there are actual or potential conflicts of interest between Danaher and Newco with respect to a particular Action: (i) Danaher may elect to have exclusive authority and control over the investigation, prosecution, defense and

B-21

##### Table of Contents

appeal of any and all Actions pending at the Separation Time which relate to or arise out of the Communications Business, the Communications Assets or the Communications Liabilities and as to which a member of the Danaher Group (other than Newco and the Newco Subs) is also named as a target or defendant thereunder, but excluding any such Actions described in clause (ii); and (ii) Newco may elect to have exclusive authority and control over the investigation, prosecution, defense and appeal of any and all Actions pending at the Separation Time which relate to or arise out of the Communications Business, the Communications Assets or the Communications Liabilities and as to which a member of the Danaher Group (other than Newco and the Newco Subs) is also named as a target or defendant thereunder, but only to the extent any such Actions primarily relate to or primarily arise in connection with the Communications Business, the Communications Assets or the Communications Liabilities and do not primarily relate to or primarily arise in connection with Excluded Liabilities; provided, however, that: (i) the Party in control of any such Action shall investigate, prosecute, defend and/or appeal such Action in good faith; (ii) the Parties shall reasonably consult with each other on a regular basis with respect to strategy and developments with respect to any such Action; (iii) the Party not in control of such Action shall have the right to participate in (but not control) and employ separate counsel in connection with the defense, compromise or settlement of such Action at its own cost and expense; and (iv) the Party in control of such Action must obtain the written consent of the other Party, such consent not to be unreasonably withheld, conditioned or delayed, to settle or compromise or consent to the entry of judgment with respect to such Action. After any such compromise, settlement, consent to entry of judgment or entry of judgment, Danaher and Newco shall agree upon a reasonable allocation to Newco of, and Newco shall be responsible for or receive, as the case may be, Newco’s proportionate share of any such compromise, settlement, consent or judgment attributable to the Communications Business, the Communications Assets or the Communications Liabilities, including its proportionate share of the reasonable costs and expenses associated with defending the same.

(b) Substitution. In the event of an Action that involves solely matters that are indemnifiable and in which the Indemnifying Party is not a named defendant, if either the Indemnitee or the Indemnifying Party so requests, the Parties shall use commercially reasonable efforts to substitute the Indemnifying Party for the named but not liable defendant to be removed from such Action and such defendants shall not be required to make any payments or contribution in connection therewith (regardless if such removal is successful or not). If such substitution or addition cannot be achieved for any reason or is not requested, the rights and obligations of the Parties regarding indemnification and the management of the defense of claims as set forth in this Article IV shall not be affected.

(c) Subrogation. In the event of payment by or on behalf of any Indemnifying Party to or on behalf of any Indemnitee in connection with any Third-Party Claim, such Indemnifying Party shall be subrogated to and shall stand in the place of such Indemnitee, in whole or in part based upon and in proportion to the amount of the Indemnitee’s Liability that the Indemnifying Party has paid, as to any events or circumstances in respect of which such Indemnitee may have any right, defense or claim relating to such Third-Party Claim against any claimant or plaintiff asserting such Third-Party Claim or against any other Person; provided, however, that in no event shall the Indemnifying Party have any rights under this Section 4.08(b) to assert any claim, action or proceeding against any customer or material supplier of the Indemnitee (whether or not the Indemnitee has been indemnified under this Agreement). Such Indemnitee shall cooperate with such Indemnifying Party in a reasonable manner, and at the cost and expense of such Indemnifying Party, in prosecuting any subrogated right, defense or claim.

Section 4.09 Payments. Indemnification required by this Article IV shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or a Loss or Liability incurred.

Section 4.10 Non-Applicability to Taxes and Employee Matters. Except as otherwise specifically provided herein, Tax matters shall be exclusively governed by the Tax Matters Agreement, employee and employee benefit matters shall be exclusively governed by the Employee Matters Agreement and, in the event of any inconsistency between the Tax Matters Agreement or the Employee Matters Agreement and this Agreement,

B-22

the Tax Matters Agreement or Employee Matters Agreement, as applicable, shall control. The procedures relating to indemnification for Tax matters and for employee and employee benefit matters shall be exclusively governed by the Tax Matters Agreement and the Employee Matters Agreement, respectively.

Section 4.11 Characterization of and Adjustment to Payments.

(a) For all Tax purposes, Danaher and Newco agree to treat any payment required by this Agreement or the Merger Agreement as either a contribution by Danaher to Newco or a distribution by Newco to Danaher, as the case may be, occurring immediately prior to the Closing Date.

(b) Notwithstanding the foregoing, any payment made pursuant to Article IV of this Agreement shall be: (i) decreased to take into account the present value of any Tax Benefit (as defined in the Tax Matters Agreement) made allowable to the Indemnitee (or any of its Affiliates) arising from the incurrence or payment of the relevant indemnified item (which Tax Benefit would not have arisen or been allowable but for such indemnified item); and (ii) increased to take into account any Tax Cost (as defined in the Tax Matters Agreement) of the Indemnitee (or any of its Affiliates) arising from the receipt of the relevant indemnity payment (but taking into account the present value of all correlative Tax Benefits resulting from the payment of such Tax Cost). For purposes of this Section 4.11(b), any Tax Benefit or Tax Cost, as applicable, shall be determined: (i) using the highest marginal rates in effect at the time of the determination; (ii) assuming the Indemnitee will be liable for such Taxes at such rate and has no Tax Attributes (as defined in the Tax Matters Agreement) at the time of the determination; and (iii) assuming that any such Tax Benefit is used at the earliest date allowable by applicable Law. The present value referred to in the first sentence of this Section 4.11(b) shall be determined using a discount rate equal to the mid term applicable federal rate in effect at the time of the payment of the relevant indemnity payment.

ARTICLE V

Section 5.01 Access to Personnel and Property. From and after the Separation Time until the sixth anniversary of the Separation Time, each of Danaher and Newco shall afford to the other and the Representatives of each, at such requesting Party’s expense on a time and materials basis, reasonable access during normal business hours, subject to the restrictions for privileged or Confidential Information set forth in this Agreement and to the requirements of any applicable Law (including, without limitation, any applicable requirements relating to privacy or disclosure of personal information) such as a code of conduct or standard of conduct (provided, however, that the Parties will arrange for appropriate substitute access of disclosure to the extent necessary to comply with any such regulation), to the personnel, properties, and, in connection with access to such personnel and properties, Information of such Party and its Subsidiaries insofar as such access is reasonably required by the other Party, upon the reasonable prior written request by such Party for access to specific and identified personnel, properties and Information, and only for the duration such access is reasonably requested and required by the other Party, and (a) relates to such other Party or, in the case of requests from Danaher, the Communications Assets prior to the Separation Time solely as may be reasonably necessary in connection with the prosecution or defense of any Action for which the requesting Party may have Liability under this Agreement (except for claims, demands or Actions between members of each Group), and in the case of requests from Newco, the Communications Business, prior to the Separation Time or (b) is reasonably required by a Party to perform its obligations under any Ancillary Agreement to which such Party or any of its Affiliates is a party; provided, however, that the Party providing such access may require that such Representatives execute a confidential non-disclosure agreement agreeing to be bound by the provisions of this Article V, unless such individual is already subject to a non-disclosure agreement containing at least substantially the same terms and conditions as this Article V with respect to Confidential Information; provided, further, that nothing in this

B-23

##### Table of Contents

Section 5.01 shall be deemed to grant Newco or any Newco Sub any license, easement, servitude or similar right with respect to any real property that is an Excluded Asset; provided, further, that the requesting Party shall reimburse the other Party for the time expended by its employees in connection therewith in an amount determined by such other Party in good faith.

Section 5.02 Witness Services. For a period of six (6) years from and after the Separation Time (or for any pending matter arising prior to the expiration of such period), each of Danaher and Newco shall use its commercially reasonable efforts to make available to the other, upon reasonable prior written request, its and its Subsidiaries’ directors, officers, employees and agents (taking into account the work schedules and other commitments of such Persons) as witnesses to the extent that (a) such Persons may reasonably be required to testify in connection with the prosecution or defense of any Action for which the requesting Party may have Liability under this Agreement or in connection with the transactions contemplated by this Agreement, the Merger Agreement or any Ancillary Agreement (except for claims, demands or Actions between members of each Group) and (b) there is no adversity in the Action between the requesting Party and the other Party except for the time and effort required in connection with the services of the officers, directors and employees and agents of the other Party. The out-of-pocket costs and expenses incurred in the provision of such witnesses shall be paid by the Party requesting the availability of such persons (provided, however, that such requesting Party must obtain written approval of the other Party prior to incurring any such costs or expenses), and such requesting Party shall reimburse the other Party for the time expended by its employees in connection therewith in an amount determined by such other Party in good faith.

Section 5.03 Privileged Matters.

(a) The respective rights and obligations of the Parties to maintain, preserve, assert or waive any or all privileges belonging to either Party or its Subsidiaries with respect to the Communications Business or the other businesses of Danaher, including the attorney-client and work product privileges (collectively, “Privileges”), will be governed by the provisions of this Section 5.03. With respect to Privileged Information (as defined below) of Danaher, Danaher will have sole authority in perpetuity to determine whether to assert or waive any or all Privileges, and Newco will not take any action (or permit any member of the Newco Group to take action) without the prior written consent of Danaher that could result in any waiver of any Privilege that could be asserted by any member of the Danaher Group under applicable Law and this Agreement. With respect to Privileged Information of Newco arising after the Separation Time, Newco will have sole authority in perpetuity to determine whether to assert or waive any or all Privileges, and Danaher will take no action (nor permit any member of the Danaher Group to take action) without the prior written consent of Newco that could result in any waiver of any Privilege that could be asserted by any member of the Newco Group under applicable Law and this Agreement. The rights and obligations created by this Section 5.03 will apply to all Information as to which a Party or its respective Groups would be entitled to assert, or has asserted, a Privilege without regard to the effect, if any, of the Transactions (“Privileged Information”).

(b) Privileged Information of the Danaher Group includes: (i) any and all Information regarding the Danaher Group and its businesses (other than Information relating to the Communications Business (“Newco Information”)), whether or not such Information (other than Newco Information) is in the possession of Newco or any Affiliate thereof; (ii) all communications subject to a Privilege between counsel for Danaher (other than counsel for the Communications Business) (including any person who, at the time of the communication, was an employee of the Danaher Group in the capacity of in-house counsel, regardless of whether such employee is or becomes an employee of NetScout, Newco or any Affiliate thereof) and any person who, at the time of the communication, was an employee of Danaher, regardless of whether such employee is or becomes an employee of Newco or any Affiliate thereof; (iii) all Information generated, received or arising after the Separation Time that discloses Privileged Information of the Danaher Group generated, received or arising prior to the Separation Time; and (iv) all Information relating to all matters relating to Danaher’s evaluation and negotiation of the Transactions.

B-24

##### Table of Contents

Privilege between counsel for the Communications Business (including any person who, at the time of the communication, was an employee of the Danaher Group in the capacity of in-house counsel, regardless of whether such employee is or remains an employee of Danaher or any Affiliate thereof) and any person who, at the time of the communication, was an employee of Danaher, Newco or any member of either Group or the Communications Business, regardless of whether such employee was, is or becomes an employee of Danaher or any of its Subsidiaries; and (iii) all Information generated, received or arising after the Separation Time that discloses Privileged Information of the Newco Group generated, received or arising after the Separation Time.

(d) Upon receipt by Danaher or Newco, or any of their respective Affiliates, as the case may be, of any subpoena, discovery or other request from any third party that actually or arguably calls for the production or disclosure of Privileged Information of the other or if Danaher or Newco, or any of their respective Affiliates, as the case may be, obtains knowledge that any current or former employee of Danaher or Newco, or any of their respective Affiliates, as the case may be, receives any subpoena, discovery or other request from any third-party that actually or arguably calls for the production or disclosure of Privileged Information of the other, Danaher or Newco, as the case may be, will promptly notify the relevant other Party of the existence of the request and will provide such other Party a reasonable opportunity to review the Information and to assert any rights it may have under this Section 5.03 or otherwise to prevent the production or disclosure of Privileged Information. Danaher or Newco, as the case may be, will not, and will cause their respective Affiliates not to, produce or disclose to any third-party any of the other Party’s Privileged Information under this Section 5.03 unless: (i) the other Party has provided its express written consent to such production or disclosure; or (ii) a court of competent jurisdiction has entered an Order not subject to interlocutory appeal or review finding that the Information is not entitled to protection from disclosure under any applicable privilege, doctrine or rule.

(e) Danaher’s transfer of books and records pertaining to the Communications Business and other Information to Newco, Danaher’s agreement to permit Newco to obtain Information existing prior to the Internal Restructuring, Newco’s transfer of books and records pertaining to Danaher, if any, and other Information to Danaher and Newco’s agreement to permit Danaher to obtain Information existing prior to the Internal Restructuring are made in reliance on Danaher’s and Newco’s respective agreements, as set forth in Section 5.01 and this Section 5.03, to maintain the confidentiality of such Information and to take the steps provided herein for the preservation of all Privileges that may belong to or be asserted by Danaher or Newco, as the case may be. The access to Information, witnesses and individuals being granted pursuant to Section 5.01 and the disclosure to Newco and Danaher of Privileged Information relating to the Communications Business or the other businesses of Danaher pursuant to this Agreement in connection with the Internal Restructuring will not be asserted by Danaher or Newco to constitute, or otherwise deem, a waiver of any Privilege that has been or may be asserted under this Section 5.03 or otherwise. Nothing in this Agreement will operate to reduce, minimize or condition the rights granted to Danaher and Newco in, or the obligations imposed upon Danaher and Newco by, this Section 5.03.

ARTICLE VI

ADDITIONAL AGREEMENTS

Section 6.01 Further Assurances. Subject to the limitations or other provisions of this Agreement, the Merger Agreement and any Ancillary Agreement: (i) each of the Parties (which shall not include NetScout unless and until the Effective Time shall have occurred) shall use reasonable best efforts (subject to, and in accordance with, applicable Law) to take promptly, or cause to be taken promptly, all actions, and to do promptly, or cause to be done promptly, and to assist and cooperate with the other Parties in doing, all things reasonably necessary, proper or advisable to consummate and make effective the transactions contemplated by and carry out the intent and purposes of this Agreement and the Ancillary Agreements, including using reasonable best efforts to obtain satisfaction of the conditions precedent to each Party’s obligations hereunder or in any Ancillary Agreement within its reasonable control and to perform all covenants and agreements herein or any Ancillary Agreement applicable to such Party; and (ii) none of the Parties (which shall not include NetScout unless and until the

B-25

##### Table of Contents

Effective Time shall have occurred) will, without the prior written consent of the other applicable Party, take any action which would reasonably be expected to prevent or materially impede, interfere with or delay the transactions contemplated by this Agreement, the Merger Agreement or any Ancillary Agreement. Without limiting the generality of the foregoing, where the cooperation of third parties, such as insurers or trustees, would be necessary in order for a Party to completely fulfill its obligations under the Merger Agreement, this Agreement or the Ancillary Agreements, such Party shall use reasonable best efforts to cause such third parties to provide such cooperation.

Section 6.02 Removal of Tangible Assets. Except as may be otherwise provided in the Ancillary Agreements or otherwise agreed to by the Parties, all tangible Communications Assets that are located at any facilities of any member of the Danaher Group shall be moved or caused to be moved by Danaher as promptly as practicable after the Separation Time from such facilities, at Danaher’s expense and in a manner so as not to unreasonably interfere with the operations of any member of the Danaher Group and not to cause damage to such facility, and such member of the Danaher Group shall provide reasonable access to such facility to effectuate the same.

Section 6.03 Danaher Guarantees. Following the Closing, if the Parties were unable to novate, assign or replace any Danaher Guarantees prior to the Closing, Newco will: (i) continue to use its reasonable best efforts to novate, assign or replace such Danaher Guarantees with NetScout as guarantor; and (ii) indemnify, defend and hold harmless Danaher and its Affiliates against, and reimburse Danaher and its Affiliates for, any Losses of Danaher and its Affiliates incurred because any such Danaher Guarantee is called upon and Danaher or its Affiliate is required to make any material payment under any such Danaher Guarantee. Newco’s reasonable best efforts with respect to this Section 6.03 shall not require Newco to take any action that would be reasonably expected to expose it or any other member of the Newco Group to any material incremental expenses or losses of benefits.

Section 6.04 Insurance Matters.

(a) Notwithstanding anything to the contrary herein, from and after the Separation Time, Newco, the Communications Assets and the Communications Business shall be, and Danaher shall use commercially reasonable efforts to cause them to continue to be, covered under insurance policies of Danaher or its Subsidiaries (as applicable), to the extent insurance coverage exists, until the Effective Time.

(b) Subject to, and other than as set forth in, Section 6.04(c) and Section 6.04(d), Newco acknowledges that: (i) coverage for Newco, the Communications Assets and the Communications Business for the period after the Effective Time under all of the insurance policies maintained by Danaher prior to the Effective Time will be terminated effective as of the Effective Time; and (ii) upon such termination, Newco, the Communications Assets and the Communications Business will cease to be covered under such policies with respect to the period after the Effective Time.

(c) For any claim asserted against any Newco or any Newco Sub after the Effective Time arising out of an occurrence taking place prior to the Effective Time (“Post-Closing Claims”), Newco and each Newco Sub may access coverage under the occurrence-based insurance policies of Danaher or its Subsidiaries (as applicable) issued or in place prior to the Effective Time under which Newco or any Newco Sub is insured (the “Pre-Closing Occurrence Based Policies”), to the extent such insurance coverage exists. After the Effective Time, Newco or any Newco Sub may seek coverage for any Post-Closing Claim under any applicable Pre-Closing Occurrence Based Policies, to the extent such insurance coverage exists, and Danaher and its Subsidiaries (as applicable) shall cooperate with Newco and the Newco Subs in connection with the tendering of such claims; provided, however, that: (i) Newco or the Newco Subs shall promptly notify Danaher of all such Post-Closing Claims and; (ii) Newco shall be responsible for the satisfaction or payment of any applicable retention, deductible or retrospective premium with respect to any Post-Closing Claim. In the event that a Post-Closing Claim relates to the same occurrence for which Danaher or its Subsidiaries is seeking coverage under Pre-Closing Occurrence Based Policies, and the limits under an applicable Pre-Closing Occurrence Based Policy are not sufficient to fund

B-26

##### Table of Contents

all covered claims of Newco or any Newco Sub (as applicable) and Danaher or its Subsidiaries (as applicable), amounts due under such a Pre-Closing Occurrence Based Policy shall be paid to the respective entities in proportion to the amounts which otherwise would be due were the limits of liability infinite. Notwithstanding anything to the contrary in this Agreement, following the Distribution Date members of the Newco Group shall have no rights or claims against or with respect to (1) any captive insurance company of Danaher or any of its Affiliates or (2) any fronted insurance program maintained by Danaher or any of its Affiliates that is not a “risk transfer” insurance program.

This Agreement, the Merger Agreement and the Ancillary Agreements, including any related annexes, schedules and exhibits, as well as any other agreements and documents referred to herein and therein, shall together constitute the entire agreement between the Parties with respect to the subject matter hereof and thereof and shall supersede all prior negotiations, agreements and understandings of the Parties of any nature, whether oral or written, with respect to such subject matter.

In addition, each of the Parties (including NetScout for so long as the Merger Agreement has not been terminated in accordance with its terms) irrevocably agrees that any legal action or proceeding with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement 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). Each of the Parties (including NetScout for so long as the Merger Agreement has not been terminated in accordance with its terms) hereby irrevocably submits with regard to any such action or proceeding for itself and in respect of its property, generally and unconditionally, to the personal jurisdiction of the aforesaid courts and agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated by this Agreement in any court other than the aforesaid courts. Each of the Parties (including NetScout for so long as the Merger Agreement has not been terminated in accordance with its terms) hereby irrevocably waives, and agrees not to assert, by way of motion, as a defense, counterclaim or otherwise, in any action or proceeding with respect to this Agreement: (a) any claim that it is not personally subject to the jurisdiction of the above named courts for any reason other than the failure to serve in accordance with this Section 9.04; (b) any claim that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether

Section 9.07 Amendments and Waivers.

(a) This Agreement may be amended and any provision of this Agreement may be waived, provided, however, that any such waiver shall be binding upon a Party only if such waiver is set forth in a writing executed by such Party and any such amendment shall be effective only if set forth in a writing executed by each of the Parties. In addition, unless the Merger Agreement shall have been terminated in accordance with its terms, any such amendment or waiver (including, for the avoidance of doubt and without limitation, any waiver of the conditions in Section 7.01 or Section 7.02) shall be subject to the written consent of NetScout. No course of dealing between or among any Persons having any interest in this Agreement shall be deemed effective to modify, amend or discharge any part of this Agreement or any rights or obligations of any Party under or by reason of this Agreement.

(b) No delay or failure in exercising any right, power or remedy hereunder shall affect or operate as a waiver thereof; nor shall any single or partial exercise thereof or any abandonment or discontinuance of steps to enforce such a right, power or remedy preclude any further exercise thereof or of any other right, power or remedy. The rights and remedies hereunder are cumulative and not exclusive of any rights or remedies that any Party would otherwise have. Any waiver, permit, consent or approval of any kind or character of any breach or default under this Agreement or any such waiver of any provision of this Agreement must satisfy the conditions set forth in Section 9.07(a) and shall be effective only to the extent in such writing specifically set forth.

Section 9.08 Early Termination. This Agreement shall terminate without further action at any time before the Closing upon termination of the Merger Agreement. If so terminated, no Party shall have any Liability of any kind to the other Party or any other Person on account of this Agreement, except as provided in the Merger Agreement.

Section 9.09 No Third-Party Beneficiaries. Except for the provisions of Article IV with respect to indemnification of Indemnitees, which is intended to benefit and be enforceable by the Persons specified therein as Indemnitees, this Agreement is solely for the benefit of the Parties and does not confer on third parties (including any employees of any member of the NetScout Group or the Newco Group) any remedy, claim, reimbursement, claim of action or other right in addition to those existing without reference to this Agreement.

Section 9.10 Assignability; Binding Effect. This Agreement is not assignable by any Party without the prior written consent of the other Parties and any attempt to assign this Agreement without such consent shall be void and of no effect. Notwithstanding anything to the contrary, and by way of expansion and not limitation, (a) Newco may assign its rights and delegate its duties under this Agreement to the Second Merger Surviving Entity (as defined in the Merger Agreement) or any other Affiliate of NetScout, (b) Danaher hereby consents and agrees to the assignment and delegation by Newco of its rights and duties under this Agreement to the Second Merger Surviving Entity upon the occurrence of the Second Merger Effective Time (as defined in the Merger Agreement) with no further action required hereunder to effect such assignment and delegation. This Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns.

Section 9.13 Construction; Interpretation. Headings of the Articles and Sections of this Agreement are for convenience of the Parties only and shall be given no substantive or interpretive effect whatsoever. The table of contents to this Agreement is for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever required by the context, any pronoun used in this Agreement or the Schedules hereto shall include the corresponding masculine, feminine or neuter forms, and the singular forms of nouns, pronouns and verbs shall include the plural and vice versa. Reference to any agreement, document or instrument means such agreement, document or instrument as amended or otherwise modified from time to time in accordance with the terms thereof, and if applicable hereof. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof,” “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The Parties have participated jointly in the negotiation and drafting of this Agreement, the Merger Agreement and the Ancillary Agreements. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties, and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any of the provisions of this Agreement.

Section 9.14 Severability. Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, such provision shall be interpreted to be only so broad as is enforceable.

Section 9.15 Counterparts. This Agreement may be executed in multiple counterparts (any one of which need not contain the signatures of more than one Party), each of which shall be deemed to be an original but all of which taken together shall constitute one and the same agreement. This Agreement, and any amendments hereto, to the extent signed and delivered by means of a facsimile machine or other electronic transmission, shall be treated in all manner and respects as an original agreement and shall be considered to have the same binding legal effects as if it were the original signed version thereof delivered in person. At the request of any Party, the other Party shall re-execute original forms thereof and deliver them to the requesting Party. No Party shall raise the use of a facsimile machine or other electronic means to deliver a signature or the fact that any signature was transmitted or communicated through the use of a facsimile machine or other electronic means as a defense to the formation of a Contract and each such Party forever waives any such defense.

Section 9.16 Plan of Reorganization. This Agreement and the Merger Agreement together shall constitute a “plan of reorganization” under Treasury Regulation Section 1.368-2(g) for the Internal Restructuring and the Distribution.

The Board of Directors:

You have requested our opinion as to the fairness, from a financial point of view, to NetScout Systems, Inc., a Delaware corporation (“NetScout”), of the Merger Consideration (defined below) to be paid by NetScout pursuant to the terms and subject to the conditions set forth in an Agreement and Plan of Merger and Reorganization (the “Merger Agreement”) proposed to be entered into among Danaher Corporation, a Delaware corporation (“Danaher”), Potomac Holding LLC, a Delaware limited liability company and wholly owned subsidiary of Danaher (“Newco”), NetScout, RS Merger Sub I, Inc., a Delaware corporation and wholly owned subsidiary of NetScout (“Merger Sub”), and RS Merger Sub II, LLC, a Delaware limited liability company and wholly owned subsidiary of NetScout (“Merger Sub II”). As more fully described in the Merger Agreement and after giving effect to the Related Transactions (defined below), NetScout and Danaher will effect a business combination of Danaher’s Communications Business (as defined below) and NetScout (the “Transaction”) in which Merger Sub will be merged with and into Newco (the “First Merger”) and, immediately following the First Merger and as part of a single integrated transaction, NetScout will cause Newco, as the surviving limited liability company in the First Merger, to be merged with and into Merger Sub II (the “Second Merger”), with Merger Sub II as the surviving limited liability company in the Second Merger. The Merger Agreement provides, among other things, that pursuant to the First Merger, each outstanding common unit representing limited liability company membership interests of Newco (“Newco Common Units”) will be converted into the right to receive that number of shares of the common stock, $0.001 par value per share, of NetScout (“NetScout Common Stock”) equal to the quotient of (i) 62.5 million shares of NetScout Common Stock plus the product of (A) 1.46 multiplied by the number of shares of NetScout Common Stock issued in any acquisition effected pursuant to the terms of the Merger Agreement divided by (ii) the aggregate number of Newco Common Units outstanding immediately prior to the effective time of the First Merger. We have been directed by the management of NetScout to assume, for purposes of our analyses and opinion, that no shares of NetScout Common Stock will be issued in connection with any acquisition pursuant to clause (A) above and, accordingly, we have evaluated the aggregate number of shares of NetScout Common Stock issuable in the First Merger on the basis of 62.5 million shares (such aggregate number of shares of NetScout Common Stock so issuable in the First Merger, the “Merger Consideration”).

We have been advised that, prior (and as a condition) to consummation of the Transaction and pursuant to the Merger Agreement and a Separation and Distribution Agreement (the “Separation Agreement” and, together with the Merger Agreement, the “Agreements”) proposed to be entered into among Danaher, Newco and NetScout, (i) Danaher will effect an internal reorganization pursuant to which, among other things, certain assets (including the outstanding capital stock of, or other equity interests in, certain subsidiaries of Danaher) and liabilities related to Danaher’s communications group business conducted under the Arbor Networks, Fluke Networks and Tektronix brands, excluding Danaher’s data communications cable installation business and communication service provider (field and test tool systems) business, will be consolidated and transferred to Newco or one or more its subsidiaries (such consolidated and transferred communications group businesses, collectively, the “Communications Business”) and (ii) Danaher will distribute to holders of the common stock, $0.01 par value per share, of Danaher all Newco Common Units held by Danaher through a split-off, followed by a clean-up spin-off, if necessary, or through a spin-off (such distribution, together with the transactions described in clause

We are acting as financial advisor to NetScout in connection with the Transaction and the Related Transactions and we will receive a fee for our services, a portion of which is payable upon delivery of this opinion and the principal portion of which is contingent upon consummation of the Transaction. NetScout also has agreed to indemnify us for certain liabilities that may arise out of our engagement and to reimburse us for expenses reasonably incurred in connection with our services. RBCCM and its affiliates have not provided investment banking or financial advisory services during the past two years to NetScout or Danaher for which compensation has been received. RBCCM and certain of our affiliates in the future may provide investment banking and financial advisory services to NetScout and Danaher, for which services RBCCM and such affiliates may receive compensation.

For the purposes of rendering our opinion, we have undertaken such review, inquiries and analyses as we deemed necessary or appropriate under the circumstances, including the following: (i) we reviewed the financial terms of drafts, each dated October 12, 2014, of the Agreements; (ii) we reviewed certain publicly available financial and other information, and certain historical operating data, with respect to NetScout made available to us from published sources and internal records of NetScout; (iii) we reviewed certain publicly available financial and other information, and certain historical operating data, with respect to the Communications Business made available to us from published sources and internal records of Danaher; (iv) we reviewed publicly available financial projections and other estimates and data relating to NetScout for the fiscal years ended March 31, 2015 and March 31, 2016 as extrapolated thereafter by the management of NetScout and financial projections and other estimates and data relating to the Communications Business prepared by the management of Danaher for the fiscal year ended December 31, 2014 as adjusted and extrapolated thereafter by the management of NetScout, in each case which we were directed to utilize for purposes of our analyses; (v) we conducted discussions with members of the senior managements of NetScout and Danaher with respect to the respective business prospects and financial outlook of NetScout and the Communications Business and also held discussions with senior management of NetScout regarding the strategic rationale and potential cost savings and other benefits expected by such management to be realized in the Transaction and the Related Transactions (collectively, the “Cost Savings”); (vi) we reviewed the reported prices and trading activity for NetScout Common Stock; (vii) we compared certain financial metrics of NetScout and the Communications Business with those of selected publicly traded companies; (viii) we reviewed the potential pro forma financial impact of the Transaction on the future financial performance of NetScout after taking into account potential Cost Savings; and (ix) we considered other

information and performed other studies and analyses as we deemed appropriate. We have not compared the financial terms of the Transaction to financial terms of other transactions given, in our view, the limited comparability of such other transactions to the Transaction.

In arriving at our opinion, we employed several analytical methodologies and no one method of analysis should be regarded as critical to the overall conclusion we have reached. Each analytical technique has inherent strengths and weaknesses, and the nature of the available information may further affect the value of particular techniques. The overall conclusion we have reached is based on all analyses and factors presented, taken as a whole, and also on application of our own experience and judgment. Such conclusion may involve significant elements of subjective judgment and qualitative analysis. We therefore give no opinion as to the value or merit standing alone of any one or more portions of such analyses or factors.

In rendering our opinion, we have assumed and relied upon the accuracy and completeness of all information that was reviewed by us, including all of the financial, legal, tax, accounting, operating and other information provided to or discussed with us by or on behalf of NetScout or Danaher (including, without limitation, financial statements and related notes), and upon the assurances of the managements of NetScout and Danaher that they are not aware of any relevant information that has been omitted or that remains undisclosed to us. We have not assumed responsibility for independently verifying and have not independently verified such information. We have assumed that the publicly available financial projections and other estimates and data relating to NetScout (as extrapolated by the management of NetScout) and the financial projections and other estimates and data relating to the Communications Business (as adjusted and extrapolated by the management of NetScout) which we have been directed to utilize in our analyses were reasonably prepared on bases reflecting the best currently available estimates and good faith judgments as to the future financial performance of NetScout and the Communications Business and the other matters covered thereby and that the financial results reflected therein will be realized in the amounts and at the times projected. We also have been advised that there currently are no audited financial statements relating to the Communications Business and we have assumed that such audited financial statements, when delivered to NetScout in connection with the Transaction, will not reflect any information that would be meaningful to our analyses or opinion. We express no opinion as to any such financial projections and other estimates and data or the assumptions upon which they were based. We have relied upon the assessments of the managements of NetScout and Danaher as to (i) the Related Transactions, including with respect to the timing thereof and assets, liabilities and financial and other terms involved, (ii) the potential impact on NetScout and the Communications Business of market and other trends and prospects for the technology industry, (iii) the products, technology and intellectual property of NetScout and the Communications Business, including the validity of, and risks associated with, such products, technology and intellectual property, (iv) the existing and future relationships, agreements and arrangements with, and NetScout’s ability to retain, key employees and customers of NetScout and the Communications Business, and (v) NetScout’s ability to integrate the Communications Business with the businesses and operations of NetScout. We have assumed that there will be no developments with respect to any such matters that would have an adverse effect on NetScout, the Communications Business, Newco, the Transaction or the Related Transactions (including the contemplated benefits thereof) or that would otherwise be meaningful in any respect to our analyses or opinion. We also have relied on estimates of the management of NetScout as to the capitalization of NetScout and Newco, including as to the number of fully diluted shares of NetScout Common Stock and Newco Common Units, as of the effective time of the First Merger and we have assumed that such number of shares or units, as the case may be, will not vary in any respect that would be meaningful to our analyses or opinion.

In rendering our opinion, we have not assumed any responsibility to perform, and have not performed, an independent evaluation or appraisal of any of the assets or liabilities (contingent or otherwise) of NetScout, the

Communications Business or any other entity (including Newco) or business, and we have not been furnished with any such valuations or appraisals. We have not assumed any obligation to conduct, and have not conducted, any physical inspection of the property or facilities of NetScout, the Communications Business or any other entity or business. We have assumed that the Transaction and the Related Transactions will be consummated in accordance with the terms of the Agreements and all applicable laws and other requirements, without waiver, modification or amendment of any material term, condition or agreement and that, in the course of obtaining the necessary regulatory or third party approvals, consents and releases for the Transaction and the Related Transactions, no delay, limitation, restriction or condition will be imposed, including any divestiture or other requirements, that would have an adverse effect on NetScout, the Communications Business, Newco, the Transaction or the Related Transactions (including the contemplated benefits thereof). We also have assumed that the Transaction and the Related Transactions will have the tax treatment as set forth in the Agreements, including that the First Merger and the Second Merger will be treated as a single integrated transaction and will together qualify as a tax-free reorganization within the meaning of Section 368 of the Internal Revenue Code of 1986, as amended. We further have assumed that Newco will retain or acquire all assets, properties and rights necessary for the operations of the Communications Business, that appropriate reserves, indemnification arrangements or other provisions have been made with respect to the liabilities of or relating to the Communications Business and that NetScout will not directly or indirectly assume or incur any liabilities that are contemplated to be excluded as a result of the Transaction, the Related Transactions or otherwise. In addition, we have assumed that the final executed Agreements will not differ, in any respect meaningful to our analyses or opinion, from the drafts of the Agreements we reviewed.

Our opinion speaks only as of the date hereof, is based on conditions as they exist and information which we have been supplied as of the date hereof, and is without regard to any market, economic, financial, legal or other circumstances or event of any kind or nature which may exist or occur after such date. We have not undertaken to reaffirm or revise this opinion or otherwise comment upon events occurring after the date hereof and do not have an obligation to update, revise or reaffirm this opinion. Our opinion, as set forth herein, relates to the relative values of NetScout and the Communications Business. We do not express any opinion as to what the value of NetScout Common Stock actually will be when issued in connection with the Transaction or the prices or range of prices at which NetScout Common Stock may trade or otherwise be transferable at any time, whether prior to or following the Transaction and the Related Transactions.

The advice (written or oral) of RBCCM and our opinion expressed herein is provided for the benefit, information and assistance of the Board of Directors of NetScout (in its capacity as such) in connection with its evaluation of the Transaction. We express no opinion and make no recommendation to any stockholder as to how such stockholder should vote or act with respect to any proposal to be voted upon in connection with the Transaction or any Related Transactions.

Our opinion addresses only the fairness, from a financial point of view and as of the date hereof, of the Merger Consideration (to the extent expressly specified herein) to NetScout. Our opinion does not in any way address any other terms, conditions, implications or other aspects of the Transaction, the Related Transactions, the Agreements or any Related Agreements, or any adjustment payment or other agreement, arrangement or understanding to be entered into in connection with or contemplated by the Transaction, the Related Transactions or otherwise. Our opinion also does not address the underlying business decision of NetScout to engage in the Transaction or any Related Transactions or the relative merits of the Transaction or any Related Transactions compared to any alternative business strategy or transaction that may be available to NetScout or in which NetScout might engage. We have not evaluated the solvency or fair value of NetScout, Danaher, the Communications Business or any other entity (including Newco) or business under any state, federal or other

laws relating to bankruptcy, insolvency or similar matters. We do not express any opinion as to any legal, regulatory, tax or accounting matters, as to which we understand that NetScout has obtained such advice as it deemed necessary from qualified professionals. Further, in rendering our opinion, we do not express any view on, and our opinion does not address, the fairness of the amount or nature of the compensation (if any) to any officers, directors or employees of any party, or class of such persons, relative to the Merger Consideration or otherwise.

The issuance of our opinion has been approved by RBCCM’s Fairness Opinion Committee.

Based on our experience as investment bankers and subject to the foregoing, including the various assumptions and limitations set forth herein, it is our opinion that, as of the date hereof, the Merger Consideration to be paid by NetScout in the First Merger is fair, from a financial point of view, to NetScout.

Very truly yours,

(b) With respect to identifying which employees and independent contractors of Danaher’s Fluke Network’s business who are not fully dedicated to the Communications Business should be treated as a Newco Employee or Newco Independent Contractor, respectively, (the “Potential Transferees”), the Parties agree to establish a human resources integration team (“Integration Team”) not later than one (1) month following the date of this Agreement consisting from time to time of eight (8) individuals (or such other number as agreed by the Parties), one-half of whom are employees of Danaher as designated by the vice president of human resources of Danaher and one half of whom are employees of NetScout as designated by the vice president of human resources of NetScout or other designee as determined by NetScout.

If such disagreement cannot be resolved in good faith, then the vice president of human resources of Danaher shall make the final determination. Notwithstanding the foregoing provisions of this Section 2.10 or the definition of “Newco Employee” or “Newco Independent Contractor” to the contrary, the identification of Newco Employees and Newco Independent Contractors shall be made subject to and in accordance with the provisions of any applicable collective bargaining obligation and Collective Bargaining Agreement and otherwise in accordance with applicable Law. Additionally, to the extent any member of the Newco Group desires to adopt or maintain a Newco Benefit Arrangement on behalf of Newco Employees prior to the Effective Time, the terms and conditions of any such Newco Benefit Arrangement must be approved and authorized by the Integration Team. If the Integration team is unable to agree on the establishment or terms and conditions of a Newco Benefit Arrangement, the respective chief human resources officers of Danaher and NetScout shall act in good faith to resolve such disagreement as soon as practicable.

No Newco Employee will accrue benefits under the Danaher U.S. Retirement Plan after the Effective Time.

Section 3.2 Non-U.S. Retirement Plan Participation.

The Pension Transfers shall be effected in accordance with applicable Law and local custom and practice; provided that if the mechanism for transfer of such assets and Liabilities is not mandated by applicable Law, then the assets and Liabilities relating to Newco Employees in respect of any applicable Danaher Non-U.S. Retirement Plan in such jurisdiction will be transferred on a projected benefit obligation basis as determined in accordance with U.S. Generally Accepted Accounting Principles and based on the applicable discount rates used in the most recent financial statements relating to the applicable Danaher Non-U.S. Retirement Plan (updated as of the Effective Time). Danaher shall use commercially reasonable efforts to provide that all assets transferred in accordance with this subsection (b) shall be transferred in the form of cash, insurance contracts or marketable securities unless otherwise required by applicable Law. NetScout shall be responsible for any and all Liabilities (including Liability for funding) and other obligations with respect to the NetScout Non-U.S. Retirement Plans.

If the assets held by any Danaher Non-U.S. Retirement Plan or Newco Benefit Arrangement assumed or retained under this Section 3.2(c) are less than the Liabilities accrued under such Danaher Non-U.S. Retirement Plan or Newco Benefit Arrangement (determined on a projected benefit obligation basis), Danaher shall transfer to NetScout an amount of cash equal to the difference between the assets

##### Table of Contents

(a) An Indemnitee shall give the Indemnifying Party notice of any matter that an Indemnitee has determined has given or would reasonably be expected to give rise to a right of indemnification under this Agreement (other than a Third-Party Claim which shall be governed by Section 9.2(b)), within twenty (20) Business Days of such determination, stating the amount of the Loss claimed, if known, and method of computation thereof, and containing a reference to the provisions of this Agreement in respect of which such right of indemnification is claimed by such Indemnitee or arises; provided, that the failure to provide such notice shall not release the Indemnifying Party from any of its obligations except and solely to the extent the Indemnifying Party shall have been materially prejudiced as a result of such failure.

(b) If a claim or demand is made against an Indemnitee by any Person who is not a party to this Agreement or an Affiliate of a Party (a “Third-Party Claim”) as to which such Indemnitee is or reasonably expects to be entitled to indemnification pursuant to this Agreement, such Indemnitee shall notify the Party that is or may be required pursuant to this Article IX to make such indemnification (the “Indemnifying Party”) in writing, and in reasonable detail, of the Third-Party Claim promptly (and in any event within thirty (30) calendar days) after receipt by such Indemnitee of written notice of the Third-Party Claim; provided, that the failure to provide notice of any such Third-Party Claim pursuant to this sentence shall not release the Indemnifying Party from any of its obligations except and solely to the extent the Indemnifying Party shall have been materially prejudiced as a result of such failure (except that the Indemnifying Party or Parties shall not be liable for any expenses incurred by the Indemnitee in defending such Third-Party Claim during the period in which the Indemnitee failed to give such notice). Thereafter, the Indemnitee shall deliver to the Indemnifying Party, promptly (and in any event within ten (10) Business Days) after the Indemnitee’s receipt thereof, copies of all notices and documents (including court papers) received by the Indemnitee relating to the Third-Party Claim.

(c) An Indemnifying Party shall be entitled (but shall not be required) to assume, control the defense of, and settle any Third-Party Claim, at such Indemnifying Party’s own cost and expense and by such Indemnifying Party’s own counsel, which counsel must be reasonably acceptable to the applicable Indemnitees, if it gives written notice of its intention to do so and agreement that the Indemnitee is entitled to indemnification under this Article IX to the applicable Indemnitees within thirty (30) calendar days of the receipt of notice from such Indemnitees of the Third-Party Claim. After such notice from an Indemnifying Party to an Indemnitee of its election to assume the defense of a Third-Party Claim, such Indemnitee shall have the right to employ separate counsel and to participate in (but not control) the defense, compromise or settlement thereof, at its own expense and, in any event, shall reasonably cooperate with the Indemnifying Party in such defense and make available to the Indemnifying Party all witnesses, pertinent and material Information and materials in such Indemnitee’s possession or under such Indemnitee’s control relating thereto as are reasonably required by the Indemnifying Party; provided, that such access shall not require the Indemnitee to disclose any information the disclosure of which would, in the reasonable judgment of the Indemnitee, result in the loss of any existing attorney-client privilege with respect to such information or violate any applicable Law.

(d) Notwithstanding anything to the contrary in this Section 9.2, in the event that (i) an Indemnifying Party elects not to assume responsibility for defending a Third-Party Claim, (ii) there exists a conflict of interest or potential conflict of interest between the Indemnifying Party and the applicable Indemnitee(s), (iii) any Third-Party Claim seeks an order, injunction or other equitable relief or relief for other than money damages against the Indemnitee, (iv) the Indemnifying Party shall not have employed counsel to represent the Indemnitee within thirty (30) calendar days after notice from the Indemnitee of such Third-Party Claim or (v) the party making such Third-Party Claim is a Governmental Authority with regulatory authority over the Indemnitee or any of its material assets, such Indemnitee(s) shall be entitled to assume the defense of such Third-Party Claim, at the Indemnifying Party’s expense, with counsel of such Indemnitee’s choosing. If the Indemnitee is conducting the defense against any such Third-Party Claim, the Indemnifying Party shall reasonably cooperate with the Indemnitee in such defense and make available to the Indemnitee all witnesses, pertinent and material Information and materials in such Indemnifying Party’s possession or under such Indemnifying Party’s control relating thereto as are reasonably required by the Indemnitee pursuant to a joint defense agreement to be entered into by Indemnitee and the Indemnifying Party; provided, that such access shall not require the Indemnifying

Party to disclose any information the disclosure of which would, in the reasonable judgment of the Indemnifying Party, result in the loss of any existing attorney-client privilege with respect to such information or violate any applicable Law.

(e) No Indemnitee may settle or compromise any Third-Party Claim without the consent of the Indemnifying Party, which consent shall not be unreasonably withheld, conditioned or delayed. If an Indemnifying Party has failed to assume the defense of the Third-Party Claim, it shall not be a defense to any obligation to pay any amount in respect of such Third-Party Claim that the Indemnifying Party was not consulted in the defense thereof, that such Indemnifying Party’s views or opinions as to the conduct of such defense were not accepted or adopted, that such Indemnifying Party does not approve of the quality or manner of the defense thereof or that such Third-Party Claim was incurred by reason of a settlement rather than by a judgment or other determination of liability.

(f) In the case of a Third-Party Claim, no Indemnifying Party shall consent to entry of any judgment or enter into any settlement of the Third-Party Claim without the consent (not to be unreasonably withheld, conditioned or delayed) of the Indemnitee if the effect thereof is to permit any injunction, declaratory judgment, other order or other non-monetary relief to be entered, directly or indirectly, against any Indemnitee, does not release the Indemnitee from all liabilities and obligations with respect to such Third-Party Claim or includes an admission of guilt or liability on behalf of the Indemnitee.

(g) Except as otherwise provided in Section 11.3, the indemnification provisions of this Article IX shall be the sole and exclusive remedy of an Indemnitee for any monetary or compensatory damages or Losses resulting from any breach of this Agreement, and each Indemnitee expressly waives and relinquishes any and all rights, claims or remedies such Person may have with respect to the foregoing other than under this Article IX against any Indemnifying Party.

Section 9.3 Indemnification Obligations Net of Proceeds Received from Third Parties.

(a) Any Liability subject to indemnification or contribution pursuant to this Article IX will be net of any proceeds received by the Indemnitee from any third party (net of any deductible or retention amount or any other third party costs or expenses incurred by the Indemnifying Party in obtaining such recovery, including any increased insurance premiums) for indemnification for such Liability that actually reduce the amount of the Liability (“Third-Party Proceeds”). Accordingly, the amount which any Indemnifying Party is required to pay pursuant to this Article IX to any Indemnitee pursuant to this Article IX will be reduced by Third-Party Proceeds theretofore actually recovered by or on behalf of the Indemnitee in respect of the related Liability. If an Indemnitee receives a payment required by this Agreement from an Indemnifying Party in respect of any Liability (an “Indemnity Payment”) and subsequently receives Third-Party Proceeds, then the Indemnitee will pay to the Indemnifying Party an amount equal to the excess of the Indemnity Payment received over the amount of the Indemnity Payment that would have been due if the Third-Party Proceeds had been received, realized or recovered before the Indemnity Payment was made.

(b) The Indemnitee shall use commercially reasonable efforts to seek to collect or recover any Third-Party Proceeds to which the Indemnitee is entitled in connection with any Liability for which the Indemnitee seeks contribution or indemnification pursuant to this Article IX; provided, that the Indemnitee’s inability to collect or recover any such Third-Party Proceeds shall not limit the Indemnifying Party’s obligations hereunder.

Section 9.4 Certain Actions; Substitution; Subrogation.

(a) Certain Actions. Notwithstanding anything to the contrary set forth in Section 9.2, Danaher may elect to have exclusive authority and control over the investigation, prosecution, defense and appeal of any and all Actions pending at the Separation Time which otherwise would be subject to this Article IX and as to which a member of the Danaher Group (other than Newco and the Newco Subs) is also named as a target or defendant

At the request of any Party, the other Party shall re-execute original forms thereof and deliver them to the requesting Party. No Party shall raise the use of a facsimile machine or other electronic means to deliver a signature or the fact that any signature was transmitted or communicated through the use of a facsimile machine or other electronic means as a defense to the formation of a Contract and each such Party forever waives any such defense.

Section 11.13 Relationship of Parties. Nothing in this Agreement shall be deemed or construed by the Parties or any third party as creating the relationship of principal and agent, partnership, joint venture or joint employer relationship between or among the Parties, it being understood and agreed that no provision contained herein, and no act of the Parties, shall be deemed to create any relationship between or among the Parties other than the relationship set forth herein.

In no event shall this Agreement be construed as establishing a partnership or joint venture or similar relationship between or among a Party and its Subsidiaries or Affiliates or to cause any such Person to be treated as the alter ego of the other.

(b) Notwithstanding the foregoing, any payment made pursuant to Article III of this Agreement shall be (i) decreased to take into account the present value of any Tax Benefit made allowable to the Indemnified Party (or any of its affiliates) arising from the incurrence or payment of the relevant indemnified item (which Tax Benefit would not have arisen or been allowable but for such indemnified item), and (ii) increased to take into account any Tax Cost of the Indemnified Party (or any of its affiliates) arising from the receipt of the relevant indemnity payment (but taking into account the present value of all correlative Tax Benefits resulting from the payment of such Tax Cost). For purposes of this Section 3.03(b), any Tax Benefit or Tax Cost, as applicable, shall be determined (i) using the highest marginal rates in effect at the time of the determination, (ii) assuming the Indemnified Party will be liable for such Taxes at such rate and has no Tax Attributes at the time of the determination, and (iii) assuming that any such Tax Benefit is used at the earliest date allowable by applicable Law.

(c) Notwithstanding Section 4.01(a), to the extent that a Party applies or causes to be applied an overpayment of Taxes as a credit toward or a reduction in Taxes otherwise payable (or a Taxing Authority requires such application in lieu of a Refund) and such overpayment of Taxes, if received as a Refund, would have been payable by such Party to the other Party pursuant to this Section 4.01, such Party shall pay such amount to the other Party no later than the Due Date of the Tax Return for which such overpayment is applied to reduce Taxes otherwise payable.

(d) If Newco or any of its Subsidiaries receives a Refund attributable to Restructuring VAT, or otherwise utilizes the benefits of a payment of Restructuring VAT (including by way of credit), Newco shall pay, or cause to be paid, to Danaher, within ten (10) days of the receipt of any such Refund or the filing of the Tax Return utilizing any such benefit the amount of such Restructuring VAT to the extent of such Refund, credit or other benefit. For purposes of determining whether Newco or any of its Subsidiaries have received such a Refund, credit or otherwise utilized the benefits of a payment of Restructuring VAT, any refund, credit or other benefit received by Newco or its Subsidiaries shall be considered to be attributable to Restructuring VAT prior to any refund, credit or other benefit being considered to be attributable to other payments of VAT. Newco agrees to claim any refund, offset, credit or other allowance attributable to Restructuring VAT as soon as reasonably possible and to furnish to Danaher at Danaher’s request all information, records and assistance reasonably necessary to verify the amount of any such refund, offset, credit or other allowance.

(e) To the extent that the amount of any Refund under this Section 4.01 is later reduced by a Taxing Authority or in a Tax Proceeding, such reduction shall be allocated to the Party to which such Refund was allocated pursuant to this Section 4.01 and an appropriate adjusting payment shall be made.

(f) Notwithstanding anything to the contrary in this Agreement, neither Danaher nor Newco shall be required to pay or cause to be paid any Refund to the other Party pursuant to this Section 4.01 if the amount of such Refund is less than $50,000.

Section 4.02 Carrybacks.

(a) The carryback of any loss, credit or other Tax Attribute from any Post-Closing Period shall be in accordance with the provisions of the Code and Treasury Regulations (and any applicable state, local or foreign Laws).

(b) Except to the extent otherwise consented to by Danaher or prohibited by applicable Law, Newco shall elect to relinquish, waive or otherwise forgo the carryback of any loss, credit or other Tax Attribute from any Post-Closing Period to any Pre-Closing Period or Straddle Period (a “Carryback”). In the event that Newco (or the appropriate member of the Newco Group) is prohibited by applicable Law to relinquish, waive or otherwise forgo a Carryback (or Danaher consents to a Carryback), Danaher shall cooperate with Newco, at Newco’s expense, in seeking from the appropriate Taxing Authority such Refund as reasonably would result from such Carryback, to the extent that such Refund is directly attributable to such Carryback, and shall pay over

E-14

##### Table of Contents

to Newco the amount of such Refund, net of any Taxes imposed on the receipt of such Refund, within ten (10) days after such Refund is received; provided, however, that Newco shall indemnify and hold the members of the Danaher Group harmless from and against any and all collateral Tax consequences resulting from or caused by any such Carryback, including, without limitation, the loss or postponement of any benefit from the use of Tax Attributes generated by a member of the Danaher Group if (i) such Tax Attributes expire unutilized, but would have been utilized but for such Carryback, or (ii) the use of such Tax Attributes is postponed to a later taxable period than the taxable period in which such Tax Attributes would have been utilized but for such Carryback.

Section 4.03 Tax Attributes.

(a) Danaher shall reasonably determine in good faith the allocation of Tax Attributes arising in a Pre-Closing Period to the Danaher Group and the Newco Group in accordance with the Code and Treasury Regulations. Danaher shall be entitled to make any determination as to (A) basis, and (B) valuation, and shall make such determinations reasonably and in good faith and consistent with Past Practice, where applicable. Danaher shall consult in good faith with NetScout regarding such allocation of Tax Attributes and determinations as to basis and valuation, and shall incorporate any reasonable comments received in writing from NetScout regarding such allocation and determinations. Danaher and Newco hereby agree to compute all Taxes for Post-Closing Periods consistently with the determination of the allocation of Tax Attributes pursuant to this Section 4.03(a) unless otherwise required by a Final Determination.

(b) To the extent that the amount of any Tax Attribute is later reduced or increased by a Taxing Authority or Tax Proceeding, such reduction or increase shall be allocated to the Party to which such Tax Attribute was allocated pursuant to Section 4.03(a).

Section 4.04 Treatment of Deductions Associated with Equity-Related Compensation.

(a) Unless otherwise prohibited by applicable Law, from and after the Closing Date, solely Danaher or any member of the Danaher Group, as the case may be, shall be entitled to claim any Tax deduction associated with the exercise in any taxable period of any Danaher stock options or stock appreciation rights by any Newco Employee.

(b) “Newco Employee” means any person employed or formerly employed by any member of the Newco Group at the time of the exercise, vesting, settlement disqualifying disposition or payment, as appropriate.

Section 4.05 Timing Differences. If pursuant to a Final Determination any Tax Benefit is made allowable to a member of the Newco Group as a result of an Adjustment to any Taxes for which a member of the Danaher Group is responsible hereunder (or Tax Attribute of a member of the Danaher Group) and such Tax Benefit would not have arisen or been allowable but for such Adjustment, or if pursuant to a Final Determination any Tax Benefit is made allowable to a member of the Danaher Group as a result of an Adjustment to any Taxes for which a member of the Newco Group is responsible hereunder (or Tax Attribute of a member of the Newco Group) and such Tax Benefit would not have arisen or been allowable but for such Adjustment, Newco or Danaher, as the case may be, shall make a payment to either Danaher or Newco, as appropriate, within thirty (30) days following such Final Determination, in an amount equal to the present value of such Tax Benefit (including any Tax Benefit made allowable as a result of the payment) determined (i) using the highest marginal rates in effect at the time of the determination, (ii) assuming the Party to which such Tax Benefit is made allowable will be liable for Taxes at such rate and has no Tax Attributes at the time of the determination, and (iii) assuming that the Tax Benefit is used at the earliest date allowable by applicable Law. The present value referred to in the preceding sentence shall be determined using a discount rate equal to the mid term applicable federal rate in effect at the time of the Final Determination.

(c) No Contrary Knowledge. Each of Danaher and Newco represents and warrants that it knows of no fact (after due inquiry) that may cause the Tax treatment of the Restructuring or the Distribution to be other than the Tax-Free Status of the Transactions.

(d) No Contrary Plan. Each of Danaher and Newco represents and warrants that neither it, nor any of its Subsidiaries, has any plan or intent to take any action which is inconsistent with any statements or representations made in the Tax Materials.

Section 6.02 Restrictions Relating to the Distribution.

(a) General. Neither Danaher nor Newco shall, nor shall Danaher or Newco permit, any Danaher Entity or any Newco Entity, respectively, to take or fail to take, as applicable, any action that constitutes a Disqualifying Action described in the definitions of Danaher Disqualifying Action and Newco Disqualifying Action, respectively.

(b) Restrictions. Prior to the first day following the second anniversary of the Distribution (the “Restriction Period”), Newco:

(i) shall continue and cause to be continued the active conduct of the Communications Business, in each case taking into account Section 355(b)(3) of the Code, in all cases as conducted immediately prior to the Distribution;

(ii) shall not voluntarily dissolve or liquidate itself or any Newco Entity (including any action that is a liquidation for federal income tax purposes);

(iii) shall not (1) enter into any Proposed Acquisition Transaction or, to the extent Newco has the right to prohibit any Proposed Acquisition Transaction, permit any Proposed Acquisition Transaction to occur, (2) redeem or otherwise repurchase (directly or through a Subsidiary) any stock, or rights to acquire stock, other than repurchases satisfying the requirements of Section 4.05(1)(b) of Revenue Procedure 96-30, 1996-1 C.B. 696 (as in effect prior to the release of Revenue Procedure 2003-48, 2003-2 C.B. 86), (3) amend its certificate of incorporation (or other organizational documents), or take any other action, whether through a stockholder vote or otherwise, affecting the relative voting rights of its capital stock (including through the conversion of any capital stock into another class of capital stock), (4) merge or consolidate with any other Person (other than pursuant to the Merger and the LLC Merger) or (5) take any other action or actions (including any action or transaction that would be reasonably likely to be inconsistent with any representation made in the Tax Materials), in each case which in the aggregate (and taking into account the Merger, the LLC Merger and any other transactions described in this Section 6.02(b)(iii)) would, when combined with any other direct or indirect changes in ownership of Newco capital stock pertinent for purposes of Section 355(e) of the Code (including the Merger and the LLC Merger), have the effect of causing or permitting one or more Persons (whether or not acting in concert) to acquire directly or indirectly stock representing a Fifty-Percent or Greater Interest in Newco or would reasonably be expected to result in a failure to preserve the Tax-Free Status of the Transactions; and

(iv) shall not, and shall not permit any member of the Newco Group, to sell, transfer, or otherwise dispose of or agree to, sell, transfer or otherwise dispose (including in any transaction treated for federal income tax purposes as a sale, transfer or disposition) of assets (including, any shares of capital stock of a Subsidiary) that, in the aggregate, constitute more than 25% of the consolidated gross assets of Newco or the Newco Group. The foregoing sentence shall not apply to (1) sales, transfers, or dispositions of assets in the Ordinary Course of Business, (2) any cash paid to acquire assets from an

E-18

##### Table of Contents

unrelated Person in an arm’s-length transaction, (3) any assets transferred to a Person that is disregarded as an entity separate from the transferor for federal income tax purposes or (4) any mandatory or optional repayment (or pre-payment) of any indebtedness of Newco or any member of the Newco Group. The percentages of gross assets or consolidated gross assets of Newco or the Newco Group, as the case may be, sold, transferred, or otherwise disposed of, shall be based on the fair market value of the gross assets of Newco and the members of the Newco Group as of the Closing Date. For purposes of this Section 6.02(b)(iv), a merger of Newco or one of its Subsidiaries with and into any Person that is not a wholly owned Subsidiary of Newco or NetScout shall constitute a disposition of all of the assets of Newco or such Subsidiary.

(c) Notwithstanding the restrictions imposed by Section 6.02(b), during the Restriction Period, Newco may proceed with any of the actions or transactions described therein, if (i) Newco shall first have requested Danaher to obtain a supplemental ruling in accordance with Section 6.03(a) to the effect that such action or transaction will not affect the Tax-Free Status of the Transactions and Danaher shall have received such a supplemental ruling in form and substance reasonably satisfactory to it, (ii) Newco shall have provided to Danaher an Unqualified Tax Opinion in form and substance reasonably satisfactory to Danaher, or (iii) Danaher shall have waived in writing the requirement to obtain such ruling or opinion. For the avoidance of doubt, the presence of a supplemental ruling, an Unqualified Tax Opinion or a waiver from Danaher shall not relieve Newco from indemnification obligations otherwise present under Article III of this Agreement. In determining whether a ruling or opinion is satisfactory, Danaher may consider, among other factors, the appropriateness of any underlying assumptions or representations used as a basis for the ruling or opinion and the views on the substantive merits.

(d) Tax Reporting. Each of Danaher and Newco covenants and agrees that it will not take, and will cause its respective Subsidiaries to refrain from taking, any position on any Income Tax Return that is inconsistent with the Tax-Free Status of the Transactions.

(e) For the avoidance of the doubt, notwithstanding the restrictions set forth in this Section 6.02, (i) Newco shall be permitted to enter into the Merger and the LLC Merger, (ii) Merger Sub II shall be permitted to liquidate or merge with and into NetScout, (iii) Newco may adopt or modify a shareholder rights plan (and issue stock in accordance therewith) that is described in or similar to the shareholder rights plan described in Revenue Ruling 90-11, 1990-1 C.B. 10.

Section 6.03 Procedures Regarding Opinions and Rulings.

(a) If Newco notifies Danaher that it desires to take one of the actions described in Section 6.02(b) (a “Notified Action”), Danaher shall cooperate with Newco and use its reasonable best efforts to seek to obtain a supplemental ruling from the IRS or an Unqualified Tax Opinion for the purpose of permitting Newco to take the Notified Action unless Danaher shall have waived the requirement to obtain such ruling or opinion. If such a ruling is to be sought, Danaher shall apply for such ruling and Danaher and Newco shall jointly control the process of obtaining such ruling. In no event shall Danaher be required to file any ruling request under this Section 6.03(a) unless Newco represents that (i) it has read such ruling request, and (ii) all information and representations, if any, relating to any member of the Newco Group, contained in such ruling request documents are (subject to any qualifications therein) true, correct and complete. Newco shall reimburse Danaher for all reasonable costs and expenses incurred by the Danaher Group in obtaining or seeking to obtain a ruling or Unqualified Tax Opinion requested by Newco within ten (10) days after receiving an invoice from Danaher therefor.

(b) Danaher shall have the right to obtain a supplemental ruling or an Unqualified Tax Opinion at any time in its sole and absolute discretion. If Danaher determines to obtain such ruling or opinion, Newco shall (and shall cause each Newco Entity to) cooperate with Danaher and take any and all actions reasonably requested by Danaher in connection with obtaining such ruling or opinion (including by making any representation or

E-19

reasonable covenant or providing any materials requested by the IRS or the law firm issuing such opinion); provided, that Newco shall not be required to make (or cause a Newco Entity to make) any representation or covenant that is untrue or inconsistent with historical facts, or as to future matters or events over which it has no control. In connection with obtaining such ruling, Danaher shall apply for such ruling and shall have sole and exclusive control over the process of obtaining such ruling. Danaher shall reimburse Newco for all reasonable costs and expenses incurred by the Newco Group in cooperating with Danaher’s efforts to obtain a supplemental ruling or Unqualified Tax Opinion within ten (10) days after receiving an invoice from Newco therefor.

(c) Except as provided in Sections 6.03(a) and (b), following the Effective Time, neither Newco nor any Newco Subsidiary shall seek any guidance from the IRS or any other Taxing Authority (whether written, verbal or otherwise) at any time concerning the Restructuring or the Distribution (including the impact of any transaction on the Restructuring or Distribution).

In the event of any dispute between the Parties as to any matter covered by this Agreement, the parties shall appoint a nationally recognized independent public accounting firm (the “Accounting Firm”) to resolve such dispute. In this regard, the Accounting Firm shall make determinations with respect to the disputed items based solely on representations made by Danaher and Newco and their respective representatives, and not by independent review, and shall function only as an expert and not as an arbitrator and shall be required to make a determination in favor of one Party only.
