1.5 Conversion of Membership Interests in the First Merger.

(a) Subject to the terms and conditions of this Agreement, at the Effective Time, by virtue of the First Merger and without any further action on the part of Danaher, Newco, NetScout, Merger Sub or any stockholder of Danaher or NetScout:

(i) any Newco Membership Interest owned by Danaher or any Subsidiary of Newco immediately prior to the Effective Time (or held in Newco’s treasury) shall be canceled and shall cease to exist, and no consideration shall be delivered in exchange therefor;

(ii) any Newco Membership Interest owned by NetScout, Merger Sub or any other Subsidiary of NetScout immediately prior to the Effective Time shall be canceled and shall cease to exist, and no consideration shall be delivered in exchange therefor;

(iii) except as provided in clauses “(i)” and “(ii)” above and subject to Sections 1.5(c) and 1.5(d), each Newco Membership Interest outstanding immediately prior to the Effective Time shall be converted into the right to receive an aggregate number of duly authorized, validly issued, fully paid and nonassessable 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 contemplated by Section 4.3(b)(v), divided by (y) the aggregate number of Newco Membership Interests issued and outstanding as of immediately prior to the Effective Time (other than shares canceled in accordance with Sections 1.5(a)(i) and 1.5(a)(ii)) (the “Per Share Merger Consideration”); and

(iv) each share of the common stock, $0.001 par value per share, of Merger Sub outstanding immediately prior to the Effective Time shall be converted into one limited liability company interest of the First Merger Surviving Entity. Pursuant to Section 18-301(b)(3) of the DLLCA, NetScout shall be admitted to the First Merger Surviving Entity as the sole member of the First Merger Surviving Entity, effective at the Effective Time, and the First Merger Surviving Entity shall continue without dissolution.

(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”). Prior to the Effective Time, NetScout shall issue and cause to be deposited with the Exchange Agent, for the benefit of the holders of Newco Common Units, for exchange in accordance with this Section 1, non-certificated shares of NetScout Common Stock represented by book entry issuable pursuant to Section 1.5 (such shares of NetScout Common Stock, together with any dividends or distributions pursuant to Section 1.6(c) received by the Exchange Agent with respect to such shares of NetScout Common Stock, are referred to collectively as the “Exchange Fund”). 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 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. At the Second Merger Effective Time, NetScout shall continue as the sole member of the Second Merger Surviving Entity, and the Second Merger Surviving Entity shall continue without dissolution.

1.11 Adjustment.

(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.

(d) None of the information to be supplied by or on behalf of Danaher or Newco for inclusion or incorporation by reference in the NetScout Form S-4 Registration Statement or the Newco Registration Statements will, at the time the NetScout Form S-4 Registration Statement or the Newco Registration Statements, respectively, is filed with the SEC or at the time it, or any amendment or supplement thereto, becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they are made, not misleading. None of the information supplied or to be supplied by or on behalf of Danaher or Newco for inclusion or incorporation by reference in the Proxy Statement/Prospectus will, at the time the Proxy Statement/Prospectus is mailed to the stockholders of NetScout or at the time of the NetScout Stockholders’ Meeting (or any adjournment or postponement thereof), contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they are made, not misleading.

Newco Registration Statements will comply as to form in all material respects with the provisions of the Securities Act, the Exchange Act and the rules and regulations promulgated by the SEC thereunder, except that no representation or warranty is made by Danaher or Newco with respect to statements made or incorporated by reference therein based on information supplied by or on behalf of NetScout for inclusion or incorporation by reference in the Newco Registration Statements.

(e) After giving effect to the Distribution and the other transactions contemplated by the Distribution Agreement, the Communications Business has not incurred any liabilities or obligations of any nature whatsoever (whether accrued, absolute, contingent or otherwise) that are required to be reflected in the Communications Business Unaudited Financial Statements in accordance with GAAP, as in effect on the date of this Agreement, except for (i) those liabilities that are reflected or reserved for in the Unaudited Interim Communications Business Financial Data, (ii) liabilities that have been incurred by the Communications Business since June 27, 2014 in the ordinary course of the Communications Business consistent with past practice, (iii) liabilities under this Agreement or incurred in connection with the Contemplated Transactions and (iv) liabilities that are not, individually or in the aggregate, material to the Communications Business, or that are described in Part 2.4(e) of the Danaher Disclosure Letter.

2.5 Absence of Changes. Except as expressly contemplated by this Agreement, since June 27, 2014 through the date of this Agreement, (a) except for discussions, negotiations and transactions related to this Agreement or the other Transaction Documents (including the Internal Restructuring described in the Distribution Agreement), the Communications Business has operated in all material respects in the ordinary course of business consistent with past practice and (b) there has not occurred any event, change, action, failure to act or transaction that, individually or in the aggregate, has had or would be reasonably expected to have, a Newco Material Adverse Effect. Except as expressly contemplated by this Agreement, since June 27, 2014 through the date of this Agreement, neither the Communications Business nor the Communications Companies have taken any actions which, had such actions been taken after the date of this Agreement, would have required the written consent of NetScout pursuant to Sections 4.2(b)(iv) and 4.2(b)(vii)-(xii).

2.6 Title to and Sufficiency of Assets.

(a) After giving effect to the Contemplated Transactions described in or contemplated by the Distribution Agreement, the Communications Companies will have good and valid title to all of the Newco Assets transferred under the Distribution Agreement. All of said assets are, or after the Distribution will be, owned by the Communications Companies free and clear of any Encumbrances, except where (i) the conveyance of any such assets requires a Consent which is not obtained, in which case the provisions of Section 1.08 of the Distribution Agreement will govern or (ii) the failure to have such good and valid title results from any liens described in Part 2.6(a) of the Danaher Disclosure Letter, liens created or otherwise imposed by the NetScout Companies or any other Permitted Encumbrance. After giving effect to the Distribution and the other Contemplated Transactions described in or contemplated by the Distribution Agreement, the Communications Companies are the lessees of, and hold valid leasehold interests in, all assets purported to have been leased by them and the Communications Companies enjoy undisturbed possession of such leased assets, except where (i) the conveyance of any such assets requires a Consent which is not obtained, in which case the provisions of Section 1.08 of the Distribution Agreement will govern or (ii) the failure to have such valid leasehold interest results from any liens described in Part 2.6(a) of the Danaher Disclosure Letter, liens created or otherwise imposed by the NetScout Companies or any other Permitted Encumbrance.

(b) At the Effective Time, the Newco Assets and the properties and rights of the Communications Companies, taken together with the benefits of any alternative arrangements provided

pursuant to Section 1.08 of the Distribution Agreement, the services available from Danaher under the Transition Services Agreement and the licenses from Danaher under the Trademark License Agreement, the IP License Agreement and the DBS License Agreement, will be sufficient for NetScout and the Communications Companies to operate the Communications Business immediately following the Effective Time in all material respects as it is currently conducted.

(c) No representation is made in this Section 2.6 with respect to title to or the sufficiency of any intellectual property assets.

2.7 Real Property; Leasehold.

(a) No Communications Company owns any real property.

(b) Part 2.7(b) of the Danaher Disclosure Letter sets forth an accurate list of each lease pursuant to which any of the Communications Companies leases or uses real property from any other Person for annual rent payments in excess of $500,000. (All real property leased to or used by the Communications Companies pursuant to the real property leases identified or required to be identified in Part 2.7(b) of the Danaher Disclosure Letter, including all buildings, structures, fixtures and other improvements leased to the Communications Companies, is referred to as the “Newco Leased Real Property.”) To the Knowledge of Danaher, there is no existing plan or study by any Governmental Body or by any other Person that challenges or otherwise adversely affects the continuation of the use or operation of any Newco Leased Real Property. Part 2.7(b) of the Danaher Disclosure Letter contains an accurate and complete list of all subleases, occupancy agreements and other Newco Contracts granting to any Person (other than any Communications Company) a right of use or occupancy of any of the Newco Leased Real Property in effect as of the date of this Agreement. Except as set forth in the leases or subleases identified in Part 2.7(b) of the Danaher Disclosure Letter, there is no Person in possession of any Newco Leased Real Property other than a Communications Company.

2.8 Intellectual Property; Privacy.

(a) Registered IP. Part 2.8(a)(i) of the Danaher Disclosure Letter identifies, as of the date of this Agreement: (i) each material item of Registered IP in which Danaher or any of its Subsidiaries (including the Communications Companies) has or purports to have (including as a result of the transfers under the Distribution Agreement) an ownership interest of any nature (whether exclusively, jointly with another Person, or otherwise) and that either: (A) covers any Newco Product or (B) that covers or that would be infringed by the operation of the Communications Business, including the manufacture, development, sale, import, support, maintenance or testing of any Newco Product or the provision of any service or test using the Newco Product (the “Newco Material Registered IP”); and (ii) any Person other than the Communication Companies that has an ownership interest in such item of Newco Material Registered IP and the nature of such ownership interest. Except as set forth in Parts 2.8(a)(ii) and 2.8(c) of the Danaher Disclosure Letter, and except with regard to non-exclusive licenses granted to Communications Companies’ distributors, resellers and end-user customers in connection with the sale, distribution or use of the Newco Products in the ordinary course of business of the Communications Companies, no material licenses, covenants not to sue, or other similar rights under the Newco Material Registered IP have been granted to any Person, including as a result of any participation in an industry association, standard setting organization or similar body.

(b) Inbound Licenses. Part 2.8(b) of the Danaher Disclosure Letter accurately identifies each Contract in effect as of the date of this Agreement pursuant to which any Intellectual Property Right or Intellectual Property is or has been licensed by any Person to Danaher, its Subsidiaries or the Communications Companies, which Contract is material to the Communications Business,

including material licenses to any Intellectual Property included in, or Intellectual Property Rights embodied by, the Newco Products or used in connection with or necessary to any development, manufacture, distribution, other commercialization, maintenance or support of the Newco Products as currently conducted (“Newco Material Inbound License”), other than (1) Contracts between Danaher or its Subsidiaries, on the one hand, and their respective employees, on the other hand, in Danaher’s standard form thereof, (2) licenses for standard commercially available off the shelf software or hardware with annual fees of less than $200,000 (“Shrink-Wrap”), (3) licenses to Open Source Code, other than that set forth in Section 2.8(i), (4) licenses for technology used exclusively by the data communication cable installation and communications service provider business of Danaher and its Subsidiaries, and (5) non-exclusive licenses to third-party software or hardware that is not incorporated into, or necessary for the development, manufacturing, testing, distribution, maintenance, or support of, any Newco Product and that is not otherwise material to the Communications Business (together with Newco Material Inbound Licenses, the “Newco Inbound Licenses”). To the Knowledge of Danaher, no material royalties or similar amounts in excess of $200,000 during any calendar year are payable by Danaher or its Subsidiaries or, after or as a result of the consummation of the transactions contemplated hereby, will be payable by the Communications Companies under the terms of any Newco Inbound Licenses other than Newco Material Inbound Licenses.

(c) Outbound Licenses. Part 2.8(c) of the Danaher Disclosure Letter identifies each material Contract, other than non-exclusive customer or sales channel Contracts for Newco Products entered into in the ordinary course of business and that does not materially differ in substance from standard form agreements and other than Contracts listed in Section 2.9(a), to which any Person has been granted any license under, or otherwise has received or acquired any right (whether or not currently exercisable) or interest in, any Newco IP, in each case in effect as of the date of this Agreement.

(d) Ownership Free and Clear. The Communications Companies exclusively own all right, title, and interest to and in the Newco IP free and clear of any Encumbrances other than licenses and similar rights granted by any Communications Company (including as set forth in Parts 2.8(a), 2.8(b) and 2.8(c) of the Danaher Disclosure Letter, and subject to the exceptions set forth in Sections 2.8(a), 2.8(b) and 2.8(c)) and other than Permitted Encumbrances. Without limiting the foregoing, to the Knowledge of Danaher, neither Danaher nor any of its Subsidiaries has transferred to, or permitted under any Contract to which Danaher or its Subsidiary is a party, any Person other than the Communications Companies to retain ownership of, or an exclusive license to: (i) the Intellectual Property Rights in or to any Derivatives of any Proprietary Newco Product, whether developed by or for Danaher or its Subsidiaries, or by or for such other Person, under any such Contract; or (ii) any interfaces developed by, with, or on behalf of, Danaher or its Subsidiaries between any Newco Product and any Person’s software or product; except in the foregoing (i) and (ii) under any Contract set forth in Parts 2.8(a), 2.8(b) or 2.8(c) of the Danaher Disclosure Letter or that is not otherwise material to the Communications Business. 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.

(e) Valid and Enforceable. To the Knowledge of Danaher, none of the material Newco IP is invalid or unenforceable.

(f) Protection of Proprietary Information. Danaher and each of its Subsidiaries (including the Communications Companies) have taken commercially reasonable steps to maintain the confidentiality of and otherwise protect and enforce their respective rights in all material proprietary information pertaining to the Communications Business and all Proprietary Newco Products, and except as set forth in Part 2.8(f) of the Danaher Disclosure Letter, no source code owned by Danaher or its Subsidiaries for any Proprietary Newco Product has been disclosed or delivered to any Person who is not a Newco Employee.

(g) Sufficiency. Danaher or its Subsidiaries owns or otherwise has, and after the Closing the Communications Companies will have (including as a result of the transfers under the Distribution Agreement), taken together with the benefits of any alternative arrangements provided pursuant to Section 1.08 of the Distribution Agreement, the services available from Danaher under the Transition Services Agreement and the licenses from Danaher under the Trademark License Agreement, the IP License Agreement and the DBS License Agreement, all Intellectual Property and Intellectual Property Rights needed to conduct the Communications Business in all material respects as it is currently conducted, including as may be necessary to so design, develop, copy, modify, make, test, support, maintain, market, license, sell or otherwise commercialize (as applicable) the Newco Products without infringing the Intellectual Property Rights of Danaher or its Affiliates; provided that the foregoing is not a representation or warranty with respect to infringement, misappropriation or other violation of third party Intellectual Property Rights or unfair competition, which solely is covered under Section 2.8(i).

(h) Third-Party Infringement of Newco IP. To the Knowledge of Danaher, no Person in the past three (3) years has infringed, misappropriated, or otherwise violated, and no Person is currently infringing, misappropriating, or otherwise violating, any material Newco IP.

(i) No Infringement of Third Party IP Rights. To the Knowledge of Danaher, the conduct of the Communications Business and of the Communications Companies as conducted in the past three (3) years, including the development, manufacture, use, import, export, offer for sale, sale or other commercialization of any of the Newco Products as so conducted, does not and has not in the past three (3) years infringed (directly, contributorily, by inducement, or otherwise), misappropriated, or otherwise violated or made unlawful use of any Intellectual Property Right of any other Person. Without limiting the generality of the foregoing, as relates to the Communications Business, including Newco IP or the Newco Products, as of the date of this Agreement, no infringement, misappropriation, or similar claim or Legal Proceeding is pending or, to the Knowledge of Danaher, threatened in writing against Danaher or its Subsidiaries (including the Communications Business and Communications Companies) or, to the Knowledge of Danaher, against any other Person who is or may be entitled to be indemnified, defended, held harmless, or reimbursed by Danaher or its Subsidiaries (including the Communications Business and Communications Companies) of the foregoing with respect to such claim or Legal Proceeding, and except as set forth in Part 2.8(i) of the Danaher Disclosure Letter, no Person has made a written request against Danaher or its Subsidiaries (including the Communications Business and Communications Companies) to be indemnified, defended, held harmless, or reimbursed with respect to any such claim or Legal Proceeding. No Proprietary Newco Product contains, is derived from, or is distributed with Open Source Code in a manner that has resulted in a requirement or condition that any Proprietary Newco Product or part thereof (1) be disclosed or distributed in source code form, (2) be licensed for the purpose of making modifications or derivative works, or (3) be redistributable at no charge.

(j) To the Knowledge of Danaher, (i) Danaher and its Subsidiaries have since January 1, 2012 materially complied with, and, as of the date of this Agreement, no Person (including any Governmental Body) has asserted a claim against, or otherwise tendered written notice to, Danaher or its Subsidiaries, in connection with the Communications Business, alleging a material violation of any

privacy policy of the Communications Companies (including those posted on the Newco Web Sites) or the applicable Legal Requirements pertaining to privacy and data (including Personal Data) protection, and (ii) there have been no unauthorized intrusions or breaches of the security of the Communications Companies’ information technology systems resulting in any material data breach.

(k) This Section 2.8 contains the sole and exclusive representations and warranties of Danaher and Newco under this Agreement with respect to Intellectual Property matters (other than Contracts required to be disclosed pursuant to Section 2.9(a)(iii)).

2.9 Contracts.

(a) Part 2.9(a) of the Danaher Disclosure Letter identifies each Newco Material Contract that is executory as of the date of this Agreement. For purposes of this Agreement, “Newco Material Contract” shall mean:

The Communications Business and each of the Communications Companies is, and since January 1, 2012 has been, in compliance with all applicable Legal Requirements, except where the failure to so comply would not, individually or in the aggregate, reasonably be expected to have a Newco Material Adverse Effect.

Since January 1, 2012, neither Danaher nor any of its Subsidiaries (with respect to the Communications Business) nor any of the Communications Companies has received any written notice or other written communication from any Governmental Body (i) regarding any actual or possible violation of, or failure to comply with, any Legal Requirement or (ii) that it is or has been the subject of any inspection, investigation, survey, audit, monitoring or other form of review by any Governmental Body.

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.

(b) Except to the extent permitted by Section 5.2(c): (i) the NetScout Board shall recommend that NetScout’s stockholders vote in favor of the issuance of shares of NetScout Common Stock pursuant to the First 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, 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. Without limiting the generality of the foregoing or Section 5.3(b) below, NetScout and Danaher each shall, promptly (and in any event, with respect to clause (x), within 10 business days after the date of this Agreement), prepare and file (x) the notifications required under the HSR Act and (y) any applicable mandatory foreign competition act filings in connection with the Merger. 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 any of the other Contemplated Transactions, shall keep the other party reasonably informed as to the status of any such Legal Proceeding or threat, and, in connection with any such Legal Proceeding, will permit authorized representatives of the other party to be present at each meeting or conference relating to any such Legal Proceeding and to have access to and be consulted in connection with any document, opinion or proposal made or submitted to any Governmental Body in connection with any such Legal Proceeding.

(b) Upon the terms and subject to the conditions set forth in this Agreement and subject to Section 5.3(b), each of NetScout, Danaher, Merger Sub and Newco agrees to use its

reasonable best efforts to take, or cause to be taken, all actions necessary or advisable to satisfy each of the conditions set forth in Sections 6 and 7, consummate the Mergers and make effective the other Contemplated Transactions (provided that no party shall be required to waive any of the conditions set forth in Sections 6 or 7, as applicable, to its obligations to consummate the Mergers and the other Contemplated Transactions). 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. NetScout shall consult with Danaher and consider the views and comments of Danaher before any of the NetScout Companies or any of their Representatives sends any emails or other documents to the Danaher Associates generally or otherwise communicate with the Danaher Associates generally, with respect to the Mergers or any of the other Contemplated Transactions. Notwithstanding the foregoing: (i) each party may, without such consultation or consent, make any public statement in response to questions from the press, analysts, investors or those attending industry conferences and make internal announcements to employees, so long as such statements are consistent with previous press releases, public disclosures or public statements made jointly by the parties (or individually, if approved by the other party), (ii) each

party may, without the prior consent of the other party hereto, issue any such press release or make any such public announcement or statement as may be required by Legal Requirement or the rules and regulations of the NASDAQ Global Select Market (with respect to NetScout) and the New York Stock Exchange (with respect to Danaher), in which case such party shall use its reasonable best efforts to consult in good faith with the other party hereto prior to issuing any such press release or making any such public announcement or statement; and (iii) NetScout need not consult with Danaher in connection with any press release, public statement or filing to be issued or made with respect to any NetScout Change in Recommendation.

(c) For purposes of this Section 5.12, “participate” means that the non-litigating party will be kept apprised of proposed strategy and other significant decisions with respect to any securityholder litigation by the litigating party (to the extent the attorney-client privilege between the litigating party and its counsel is not undermined or otherwise affected), and the non-litigating party may offer comments or suggestions with respect to the litigation but will not be afforded any decision making power or authority over the litigation, except for the right to consent to any settlement as set forth in Section 5.12(a) or Section 5.12(b), as applicable.

5.13 Financial Statements.

(a) Danaher shall engage its auditors to perform an audit of the financial statements of (x) the Communications Business and (y) Newco (before giving effect to the Internal Restructuring) and will use its reasonable best efforts to provide NetScout, as promptly as practicable after the date hereof and prior to November 15, 2014, with (i) the audited combined and consolidated financial statements of (x) the Communications Business and (y) Newco (before giving effect to the Internal Restructuring), including the combined and consolidated balance sheets of (x) the Communications Business and (y) Newco (before giving effect to the Internal Restructuring) as of December 31, 2012 and December 31, 2013, and the combined and consolidated statements of earnings, cash flows and parent equity of (x) the Communications Business and (y) Newco (before giving effect to the Internal Restructuring) for the years ended December 31, 2011, December 31, 2012 and December 31, 2013 together with a report on the financial statements from the independent accounts for the Communications Business (collectively, the “Audited Financial Statements”) and (ii) the unaudited combined and consolidated financial statements of (x) the Communications Business and (y) Newco (before giving effect to the Internal Restructuring) for applicable interim periods ending prior to the date of this Agreement required for SEC filings, prepared from the books and records of Danaher and its Subsidiaries and in accordance with GAAP consistently applied and the rules and regulations of the SEC, including the requirements of Regulation S-X and the Public Company Accounting Oversight Board Rules, and which present fairly in all material respects the combined financial position and combined results of operations of (x) the Communications Business and (y) Newco (before giving effect to the Internal Restructuring) as of the dates and for the periods shown therein (except as otherwise noted therein) (it being understood, however, that the Communications Business has not been operating historically as a separate “standalone” entity or reporting segment and, therefore, the Audited Financial Statements and the unaudited interim financial statements of the Communications Business will reflect certain cost allocations made that may not reflect what would have been incurred if the Communications Business had been a standalone business). 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.

(b) Danaher shall use its reasonable best efforts to, as promptly as practicable and no later than forty five (45) calendar days after the end of any fiscal quarter or sixty (60) calendar days after the end of any fiscal year (or as promptly thereafter as possible), prepare and furnish to NetScout copies of financial statements of the Communications Business as of and for the periods ending on any fiscal quarterly and annual periods ending after the date of this Agreement and prior to the Closing Date, in each case together with the notes thereto, and prepared from the books and records of Danaher

and its Subsidiaries and in accordance with GAAP with no exception or qualification thereto (it being understood, however, that the Communications Business has not been operating historically as a separate “standalone” entity or reporting segment and, therefore, the financial statements of the Communications Business will reflect certain cost allocations made that may not reflect what would have been incurred if the Communications Business had been a standalone business) applied on a consistent basis through the periods involved (except as may otherwise be required under GAAP) and the rules and regulations of the SEC, including the requirements of Regulation S-X, and, in the case of the combined financial statements of the Communications Business for any fiscal year, Danaher shall use its reasonable best efforts to ensure that such financial statements shall be audited and accompanied by a report of the independent accountants for the Communications Business and for any quarterly period, Danaher shall use its reasonable best efforts to ensure that such financial statements shall be reviewed by the independent accountants for the 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). 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 for actions taken at the request of NetScout pursuant to this Section 5.13(c) following the Closing.

5.14 Financing. 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.

5.15 Covenant Not to Compete.

(a) In furtherance of the Mergers and the Contemplated Transactions, Danaher covenants and agrees that, for a period beginning on the Effective Time and ending on the two (2) year anniversary of the Effective Time, neither Danaher nor any of its Subsidiaries shall, without the prior written consent of NetScout, engage in, directly or indirectly, the Communications Business as conducted as of the Effective Time (the “NetScout Restricted Business”) anywhere throughout the world. Notwithstanding anything to the contrary in the foregoing:

(i) Nothing in this Section 5.15(a) shall prohibit Danaher or its Subsidiaries from engaging in the businesses conducted by Danaher or its Subsidiaries (excluding the Communications Business) as of the Effective Time;

(ii) The restrictions set forth in this Section 5.15(a) shall not apply to any joint venture or non-consolidated entity in which Danaher or its Subsidiaries owns a non-controlling interest;

(iii) Danaher may acquire interests in or securities of any Person engaged in the NetScout Restricted Business where the revenues of such Person that are derived from the NetScout Restricted Business are (A) thirty-five percent (35%) or less of such Person’s total revenues or (B) less than $50,000,000 annually;

(iv) In the event that Danaher completes a business combination transaction with a Person that is engaged in any NetScout Restricted Business, which transaction results in the holders of the voting securities of Danaher outstanding immediately prior to the consummation of such transaction owning less than 50% of the voting power of the voting securities of Danaher or the surviving entity in the transaction or any parent thereof outstanding immediately after the consummation of such transaction, such surviving entity or parent or any of its Subsidiaries or Affiliates (but not Danaher or any of its Subsidiaries) may engage in any NetScout Restricted Business;

(v) Nothing set forth in this Section 5.15(a) shall prohibit Danaher or its Subsidiaries from owning not in excess of 10% in the aggregate of any class of capital stock or other equity interest of any publicly traded Person engaged in the NetScout Restricted Business;

(vi) Danaher may acquire interests in or securities of any Person as an investment by their pension funds or funds of any other benefit plan of Danaher whether or not such Person is engaged in any NetScout Restricted Business; and

(vii) Danaher may perform its obligations under this Agreement and the Transaction Documents.

The parties hereto acknowledge and agree that nothing herein shall be deemed to require Danaher to give notice to or obtain the consent of NetScout in order to engage in any activity or transaction of the types described in Section 5.15(a)(i) through (vii).

(b) Danaher acknowledges and agrees that the covenants included in Section 5.15(a) are, taken as a whole, reasonable in their geographic and temporal coverage and Danaher shall not raise any issue of geographic or temporal reasonableness in any proceeding to enforce such covenant; provided, however, that (i) if the final judgment of a court of competent jurisdiction declares that any term or provision of this Section 5.15 is invalid or unenforceable, the parties hereto agree that the court making such determination shall have the power to limit the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Section 5.15 shall be enforceable as so modified and (ii) in the event such court does not exercise the power granted to it in the prior clause, the parties hereto agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term. Danaher acknowledges and agrees that in the event of a breach by Danaher of the provisions of this Section 5.15, monetary damages shall not constitute a sufficient remedy. Consequently, in the event of any such breach, NetScout may, in addition to any other rights and remedies existing in its favor, apply to any court of law or equity of competent jurisdiction for specific performance and/or preliminary and final injunctive relief or other relief in order to enforce or prevent any violation of the provisions hereof, without the necessity of proving actual damages or posting a bond.

Notwithstanding any other provision of this Agreement to the contrary, other than as provided in this Section 8.3(d), the parties agree that the payments contemplated by Section 8.3(b) and Section 8.3(c) represent the sole and exclusive remedy of Danaher in respect of a termination pursuant to Section 8.1 and that, except for the payment expressly set forth in this Section 8.3, Danaher and its Affiliates shall not be entitled to bring or maintain any other claim, action or proceeding against NetScout or its Affiliates, shall be precluded from any other remedy against the other, at law or in equity or otherwise, and shall not seek to obtain any recovery, judgment or damages of any kind against NetScout (or any partner, member, stockholder, director, officer, employee, Subsidiary, affiliate, agent or other representative of the NetScout Companies) in connection with or arising out of the termination of this Agreement, any breach of or by any party giving rise to such termination or the failure of the Mergers and the other Contemplated Transactions to be consummated.

This Agreement, including the schedules, exhibits and amendments hereto and the other agreements referred to herein constitute the entire agreement and supersede all prior agreements and understandings, both written and oral, among or between any of the parties with respect to the subject matter hereof and thereof; provided, however, that the Confidentiality Agreement shall not be superseded and shall remain in full force and effect in accordance with its terms (it being understood that no provision in the Confidentiality Agreement shall limit any party’s rights or remedies in the case of fraud). This Agreement may be executed in several counterparts, each of which shall be deemed an original and all of which shall constitute one and the same instrument.

9.5 Applicable Law; Jurisdiction; Specific Performance; Remedies. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof. In any action between any of the parties arising out of or relating to this Agreement or any of the Contemplated Transactions: (a) each of the parties irrevocably and unconditionally consents and submits

to the exclusive jurisdiction and venue of the Court of Chancery of the State of Delaware or, if under applicable Legal Requirements, exclusive jurisdiction over such matter is vested in the federal courts, any federal court in the State of Delaware and any appellate court from any thereof; and (b) each of the parties irrevocably waives the right to trial by jury.

The parties hereto hereby agree that a final judgment in any such claim, suit, action or other proceeding will be conclusive, subject to any appeal, and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable law. The parties agree that irreparable damage would occur and that the parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to specific performance and injunctive or other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement without the requirement for the posting of any bond, this being in addition to any other remedy to which they are entitled at law or in equity.
