The Company and its counsel shall be given a reasonable opportunity to review and comment on the Schedule TO and any other Offer Document each time before any such document is filed with the SEC, and Parent and Merger Subsidiary shall give reasonable and good faith consideration to any comments made by the Company and its counsel. Parent and Merger Subsidiary shall promptly provide the Company and its counsel with (A) any comments or other communications, whether written or oral, that Parent, Merger Subsidiary or their counsel may receive from time to time from the SEC or its staff with respect to the Schedule TO or Offer Documents promptly after receipt of those comments or other communications and (B) a reasonable opportunity to participate in the response of Parent and Merger Subsidiary to those comments and to provide comments on that response (to which reasonable and good faith consideration shall be given). Parent and Merger Subsidiary shall use their reasonable best efforts to give the Company the opportunity to participate with Parent, Merger Subsidiary or their counsel in any substantive discussions or meetings with the SEC. The Company hereby consents to the inclusion in the Offer Documents of the Company Board Recommendation as it may be amended or modified, and until but not after it is withdrawn, in each case as permitted by this Agreement.

Section 2.02. Company Action. (a) The Company hereby consents to the Offer and represents that the board of directors of the Company (the “Board of Directors”), at a meeting duly called and held has unanimously (i) determined that this Agreement and the transactions contemplated hereby,

including the Offer and the Merger, are fair to and in the best interests of the Company’s stockholders, (ii) approved, adopted and declared advisable this Agreement and the transactions contemplated hereby, including the Offer and the Merger, in accordance with the requirements of Delaware Law and (iii) resolved, subject to ‎Section 7.03(b), to recommend acceptance of the Offer by the Company’s stockholders (such recommendation, the “Company Board Recommendation”). The Company has been advised that all of its directors and executive officers who own Shares intend to tender their Shares pursuant to the Offer. The Company shall, or shall cause its transfer agent to, as promptly as practicable furnish Parent with a list of its stockholders, mailing labels and any available listing or computer file containing the names and addresses of all record holders of Shares and lists of securities positions of Shares held in stock depositories (including the Depository Trust Company), in each case true and correct as of the most recent practicable date, and shall provide to Parent such additional information (including updated lists of stockholders, mailing labels and lists of securities positions) and such other assistance in communicating with the record and beneficial owners of the Shares as Parent may reasonably request in connection with the Offer.

(b) On the Offer Commencement Date, as soon as practicable after the Schedule TO has been filed, the Company shall file with the SEC and disseminate to holders of Shares, in each case as and to the extent required by applicable U.S. federal securities laws, a Solicitation/Recommendation Statement on Schedule 14D-9 (together with any amendments or supplements thereto, the “Schedule 14D-9”) that, subject to ‎Section 7.03(b), shall include the Company Board Recommendation, provided, however, that for so long as the Board of Directors shall not have made an Adverse Recommendation Change, at the Company’s request, Parent and Merger Subsidiary shall, at their own expense, disseminate any Schedule 14D-9 required to be disseminated to holders of Shares. The Company represents that the Schedule 14D-9 shall include in their entirety the separate fairness opinions of Xxxxxxx, Xxxxx & Co. and Leerink Partners LLC (together, the “Company Financial Advisors”) and a description of such fairness opinions and the financial analyses relating thereto. The Schedule 14D-9 shall also contain the notice of appraisal required to be delivered by the Company under Section 262(d) of Delaware Law at the time the Company first files the Schedule 14D-9 with the SEC. The Company shall cause the Schedule 14D-9 to comply in all material respects with the requirements of the 1934 Act and all other Applicable Law. Each of the Company, Parent and Merger Subsidiary agrees promptly to correct any information provided by it or any of their respective Affiliates for use in the Schedule 14D-9 if and to the extent that such information shall have become (or shall have become known to be) false or misleading in any material respect. The Company shall cause the Schedule 14D-9 as so corrected to be filed with the SEC and to be disseminated to holders of Shares, in each case to the extent required by applicable U.S. federal securities laws or the rules and regulations of Nasdaq. Parent will furnish to the Company the information relating to Parent or Merger Subsidiary required by the 1934 Act to be set forth in

the Schedule 14D-9. Parent, Merger Subsidiary and their counsel shall be given a reasonable opportunity to review and comment on the Schedule 14D-9 each time before it is filed with the SEC, and the Company shall give reasonable and good faith consideration to any comments made by Parent, Merger Subsidiary and their counsel. The Company shall promptly provide Parent, Merger Subsidiary and their counsel with (i) any comments or other communications, whether written or oral, that the Company or its counsel may receive from time to time from the SEC or its staff with respect to the Schedule 14D-9 promptly after receipt of those comments or other communications and (ii) a reasonable opportunity to participate in the Company’s response to those comments and to provide comments on that response (to which reasonable and good faith consideration shall be given). The Company shall use its reasonable best efforts to give Parent the opportunity to participate with the Company or its counsel in any substantive discussions or meetings with the SEC.

ARTICLE 3

The Merger

Section 3.01. The Merger. (a) As soon as practicable on or following the Acceptance Date (and in no event later than one Business Day following the Acceptance Date), Merger Subsidiary shall be merged (the “Merger”) with and into the Company in accordance with Delaware Law, whereupon, the separate existence of Merger Subsidiary shall cease and the Company shall be the surviving corporation (the “Surviving Corporation”). The Merger shall be governed by Section 251(h) of Delaware Law and shall be effected as soon as practicable following the consummation of the Offer.

(b) Subject to the provisions of ‎Article 10, the closing of the Merger (the “Closing”) shall take place in New York City at the offices of Xxxxx Xxxx & Xxxxxxxx LLP, 000 Xxxxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx, 00000 as soon as possible, but in any event no later than the Business Day after the date the conditions set forth in Article 10 (other than conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or, to the extent permissible under Applicable Law, waiver of those conditions by the party or parties entitled to the benefit thereof at the Closing) have been satisfied or, to the extent permissible under Applicable Law, waived by the party or parties entitled to the benefit of such conditions, or at such other place or time as Parent and the Company may mutually agree consistent with Section 251(h) of Delaware Law (the date on which the Closing occurs, the “Closing Date”).

(c) At the Closing, the Company and Merger Subsidiary shall file a certificate of merger with the Delaware Secretary of State and make all other filings or recordings required by Delaware Law in connection with the Merger. The Merger shall become effective at such time (the “Effective Time”) as such certificate of merger is duly filed with the Delaware Secretary of State (or at such

later time as may be agreed to by the Company and Merger Subsidiary prior to the Effective Date and specified in such certificate of merger).

(d) From and after the Effective Time, the Surviving Corporation shall possess all the rights, powers, privileges and franchises and be subject to all of the obligations, liabilities, restrictions and disabilities of the Company and Merger Subsidiary, all as provided under Delaware Law.

Section 3.02. Conversion of Shares. At the Effective Time:

(a) Except as otherwise provided in ‎Section 3.02(b) or ‎Section 3.04, each Share outstanding immediately prior to the Effective Time shall be converted into the right to receive the Offer Price in cash, without interest (the “Merger Consideration”). As of the Effective Time, all such Shares shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and shall thereafter represent only the right to receive the Merger Consideration in accordance with ‎Section 3.03.

(b) Each Share held by the Company as treasury stock (other than Shares in a Company Plan) immediately prior to the Effective Time and each Share that has been irrevocably accepted for purchase by Merger Subsidiary in the Offer (which shall be treated as set forth in ‎Section 2.01(d)), shall be canceled, and no payment shall be made pursuant to the Merger with respect thereto.

(c) Each share of common stock of Merger Subsidiary outstanding immediately prior to the Effective Time shall be converted into and become one fully paid and nonassessable share of common stock of the Surviving Corporation with the same rights, powers and privileges as the shares so converted and shall constitute the only outstanding shares of capital stock of the Surviving Corporation.

Section 3.03. Surrender and Payment. (a) Prior to the Effective Time, Parent shall appoint an agent reasonably acceptable to the Company (the “Paying Agent”) for the purpose of exchanging for the Merger Consideration (i) certificates representing Shares (the “Certificates”) and (ii) uncertificated Shares (the “Uncertificated Shares”). Parent shall, or shall cause one of its Affiliates to, make available to the Paying Agent, as needed, the Merger Consideration to be paid in respect of the Certificates and the Uncertificated Shares. Promptly after the Effective Time (and in any event within five Business Days), Parent shall send, or shall cause the Paying Agent to send, to each holder of Shares at the Effective Time, a letter of transmittal and instructions (which shall specify that the delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the Certificates or transfer of the Uncertificated Shares to the Paying Agent) for use in such exchange.

(b) Each holder of Shares that have been converted into the right to receive the Merger Consideration shall be entitled to receive, upon (i) surrender to

the Paying Agent of a Certificate, together with a properly completed letter of transmittal, or (ii) receipt of an “agent’s message” by the Paying Agent (or such other evidence, if any, of transfer as the Paying Agent may reasonably request) in the case of a book-entry transfer of Uncertificated Shares, the Merger Consideration payable for each Share represented by such Certificate or for each such Uncertificated Share. Until so surrendered or transferred, as the case may be, each such Certificate or Uncertificated Share shall represent after the Effective Time for all purposes only the right to receive the Merger Consideration.

(c) If any portion of the Merger Consideration is to be paid to a Person other than the Person in whose name the surrendered Certificate or the transferred Uncertificated Share is registered, it shall be a condition to such payment that (i) either such Certificate shall be properly endorsed or shall otherwise be in proper form for transfer or such Uncertificated Share shall be properly transferred and (ii) the Person requesting such payment shall pay to the Paying Agent any transfer or other Taxes required as a result of such payment to a Person other than the registered holder of such Certificate or Uncertificated Share or establish to the satisfaction of the Paying Agent that such Tax has been paid or is not payable.

(d) After the Effective Time, there shall be no further registration of transfers of Shares. If, after the Effective Time, Certificates or Uncertificated Shares are presented to the Surviving Corporation or the Paying Agent, they shall be canceled and exchanged for the Merger Consideration provided for, and in accordance with the procedures set forth, in this ‎Article 3.

(e) Any portion of the Merger Consideration made available to the Paying Agent pursuant to ‎Section 3.03(a) (and any interest or other income earned thereon) that remains unclaimed by the holders of Shares 12 months after the Effective Time shall be returned to Parent or one of its Affiliates, upon demand, and any such holder who has not exchanged such Shares for the Merger Consideration in accordance with this ‎Section 3.03 prior to that time shall thereafter look only to the Surviving Corporation for payment of the Merger Consideration in respect of such Shares, without any interest thereon. Notwithstanding the foregoing, neither Parent nor any of its Affiliates shall be liable to any holder of Shares for any amounts paid to a public official pursuant to applicable abandoned property, escheat or similar laws.

(f) Any portion of the Merger Consideration made available to the Paying Agent pursuant to ‎Section 3.03(a) to pay for Shares for which appraisal rights have been perfected shall be returned to Parent or one of its Affiliates, upon demand, provided that in such case, until 12 months after the Effective Time, Parent shall make available to the Paying Agent, as needed, the Merger Consideration to be paid in respect of such Shares to any holder thereof that withdraws or otherwise loses the right to appraisal under Section 262 of Delaware Law.

Section 3.04. Dissenting Shares. Notwithstanding ‎Section 3.02, Shares outstanding immediately prior to the Effective Time and held by a holder who is entitled to demand and properly demands appraisal rights in accordance with Section 262 of Delaware Law and who has otherwise complied with all applicable provisions of Section 262 of Delaware Law shall not be converted into the right to receive the Merger Consideration, but shall be entitled only to such rights as are granted by Section 262 of Delaware Law unless such holder fails to perfect, withdraws or otherwise loses the right to appraisal under Section 262 of Delaware Law. If, either before or after the Effective Time, such holder fails to perfect, withdraws or loses the right to appraisal under Section 262 of Delaware Law, such Shares shall be treated as if they had been converted as of the Effective Time into the right to receive the Merger Consideration in accordance with ‎Section 3.02(a). The Company shall give Parent vi) notice within 24 hours of any demands for appraisal, attempted withdrawals of such demands and any other instruments served pursuant to Applicable Law that are received by the Company relating to stockholders’ rights of appraisal, and vii) the opportunity to direct all negotiations and proceedings with respect to such demands and the exercise of appraisal rights under Section 262 of Delaware Law, provided the foregoing shall not require the Company to agree to make any payment in respect of such demand or exercise prior to the Effective Time. Except with the prior written consent of Parent, the Company shall not voluntarily make any payment with respect to, offer to settle or settle such demands or approve any withdrawal of any such demands.

Section 3.05. Equity Awards. (a) Subject to ‎Section 3.06 at the Acceptance Date, each outstanding option to purchase Shares (a “Company Stock Option”) granted under the Equity Plans whether or not exercisable and whether vested or unvested, without any action on the part of the holder thereof, shall be cancelled in exchange for a single lump sum cash payment (subject to any applicable withholding tax), without interest, in an amount equal to the product of (1) the number of shares of Company Common Stock subject to such Company Stock Option (whether vested or unvested) and (2) the excess, if any, of the Merger Consideration over the exercise price per share of such Company Stock Option (it being understood that, each unexercised Company Stock Option with an exercise price equal to or greater than the Merger Consideration shall be cancelled at the Acceptance Date without consideration therefor), which amount shall be paid by the Company to the holder of the Company Stock Option promptly following the Acceptance Date.

(b) Subject to ‎Section 3.06, at the Acceptance Date, each outstanding restricted stock unit (each, a “Company Stock Unit”) granted under the Equity Plans whether vested or unvested, without any action on the part of the holder thereof, shall be cancelled in exchange for a lump sum cash payment (subject to any applicable withholding tax) in an amount equal to the product of (1) the Merger Consideration and (2) the number of shares of Company Common Stock subject to such Company Stock Unit (whether vested or unvested), which number,

in the case of Company Stock Units subject to performance vesting criteria, shall be determined as if the applicable performance objectives had been achieved at the target performance level, which amount shall be paid by the Company to the holder of the Company Stock Unit promptly following the Acceptance Date.

(c) Any payment to which a holder of a Company Stock Option or Company Stock Unit becomes entitled pursuant to ‎Section 3.05(a) or ‎Section 3.05(b) shall be made through the Surviving Corporation’s payroll. Notwithstanding the foregoing, for any Company Stock Unit that constitutes deferred compensation within the meaning of Section 409A of the Code, if making the payment as set forth in ‎Section 3.05(b) would subject the holder of such Company Stock Unit to additional tax under Section 409A of the Code, such payment shall be made on the date that it would be made under the applicable Equity Plan absent the application of this ‎Section 3.05.

(d) Prior to the Acceptance Date, the Company shall (i) use its reasonable efforts to obtain any consents from holders of Company Stock Options and Company Stock Units granted under the Company’s Equity Plans and (ii) make any amendments to the terms of such Equity Plans that, in the case of either clauses ‎(i) or ‎(ii), which the Company reasonably determines are reasonable and necessary to give effect to the transactions contemplated by Sections ‎3.05(a), ‎3.05(b) and ‎3.05(c)‎.

(e) At or prior to the Acceptance Date, the Company, the Board of Directors or the Compensation Committee of the Board of Directors, as applicable, shall adopt any resolutions and take any actions which the Company reasonably determines are reasonably necessary to effectuate the provisions of this ‎Section 3.05. Prior to adopting any such resolutions or taking any such action, the Company shall provide Parent with a reasonable opportunity to review such resolutions or action.

Section 3.06. Adjustments. If, during the period between the date of this Agreement and the Effective Time, the outstanding Shares (or securities convertible or exchangeable into, or exercisable for, Shares) shall be changed into a different number of shares or a different class by reason of any reclassification, recapitalization, stock split (including reverse stock split) or combination, exchange or readjustment of Shares, as applicable, or stock dividend thereon with a record date during such period (excluding, for the avoidance of doubt, any change that results from any issuance of Shares permitted by ‎Section 7.01(c)), the Offer Price, the Merger Consideration and any other amounts payable pursuant to this Agreement shall be appropriately adjusted. Nothing in this ‎Section 3.06 shall be construed to permit any party to take any action that is otherwise prohibited or restricted by any other provision of this Agreement.

Section 3.07. Withholding Rights. Notwithstanding any provision contained herein to the contrary, each of the Paying Agent, the Company, the Surviving Corporation and Parent shall be entitled to deduct and withhold from

the consideration otherwise payable to any Person pursuant to Articles ‎2 and ‎3 such amounts as it is required to deduct and withhold with respect to the making of such payment under any provision of Tax law. If the Paying Agent, the Company, the Surviving Corporation or Parent, as the case may be, so withholds amounts, such amounts shall be treated for all purposes of this Agreement as having been paid to such Person in respect of which the Paying Agent, the Surviving Corporation or Parent, as the case may be, made such deduction and withholding.

Section 3.08. Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by the Surviving Corporation, the posting by such Person of a bond in accordance the Paying Agent’s customary practices, in such reasonable amount as the Surviving Corporation may direct, as indemnity against any claim that may be made against the Surviving Corporation with respect to such Certificate and the payment of any customary fees for lost, stolen or destroyed Certificates charged by the Paying Agent, the Paying Agent shall pay, in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration to be paid in respect of the Shares represented by such Certificate, as contemplated by this ‎Article 3.

The certificate of incorporation of the Company in effect at the Effective Time shall be amended and restated in its entirety at the Effective Time to be identical to the certificate of incorporation of Merger Subsidiary in effect immediately prior to the Effective Time, except that all references therein to Merger Subsidiary shall be amended pursuant to the certificate of merger and shall become references to the Surviving Corporation and the provisions of the certificate of incorporation of Merger Subsidiary relating to the incorporator of Merger Subsidiary shall be omitted, until thereafter amended in accordance with Applicable Law.

Section 4.02. Bylaws.

(e) The Company and its Subsidiaries have established and maintain disclosure controls and procedures (as defined in Rule 13a-15 under the 1934 Act).

There has been no material amendment to, written interpretation of or announcement (whether or not written) by the Company or any of its Subsidiaries relating to, or change in employee participation or coverage under, any International Plan, in each case, that would increase materially the expense of maintaining such International Plan above the level of expense incurred in respect thereof for the most recent fiscal year ended prior to the date hereof.

From the date hereof until the Effective Time, and subject to, upon reasonable prior written notice and during normal business hours, Applicable Law and the Confidentiality Agreement, the Company shall (i) give Parent, its counsel, financial advisors, auditors and other authorized representatives reasonable access to the offices, properties, assets, books and records of the Company and the Subsidiaries, (ii) furnish to Parent, its counsel, financial advisors, auditors and other authorized representatives such financial and operating data and other information as such Persons may reasonably request and (iii) instruct the employees, counsel, financial advisors, auditors and other authorized representatives of the Company and its Subsidiaries to reasonably cooperate with Parent in its investigation of the Company and its Subsidiaries; provided, however, that the Company may restrict the foregoing access and the disclosure of information pursuant to this ‎Section 7.02 to the extent that (A) in the reasonable good faith judgment of the Company, any Applicable Law requires the Company or its Subsidiaries to restrict or prohibit access to any such properties or information, (B) in the reasonable good faith judgment of the Company, the information is subject to confidentiality obligations to a Third Party or (C) disclosure of any such information or document would reasonably be expected to result in the loss of attorney-client privilege; provided, further, that with respect to clauses (A) through (C) of this

‎Section 7.02, the Company shall use its commercially reasonable efforts to (1) obtain the required consent of any such Third Party to provide such access or disclosure if requested by Parent, (2) develop an alternative to providing such information so as to address such matters that is reasonably acceptable to Parent and the Company and (3) in the case of clauses (A) and (C), enter into a joint defense agreement or implement such other techniques if the parties determine that doing so would reasonably permit the disclosure of such information without violating Applicable Law or jeopardizing such privilege. Any investigation pursuant to this Section shall be conducted in such manner as not to interfere unreasonably with the conduct of the business of the Company and its Subsidiaries. No information or knowledge obtained in any investigation pursuant to this Section shall affect or be deemed to modify any representation or warranty made by the Company hereunder.

Section 7.03. No Solicitation; Other Offers. (a) General Prohibitions. Neither the Company nor any of its Subsidiaries shall, nor shall the Company or any of its Subsidiaries authorize or permit any of its or their officers, directors, employees, investment bankers, attorneys, accountants, consultants or other agents or advisors (“Representatives”) to, directly or indirectly, (i) solicit, initiate or take any action to knowingly facilitate or encourage the submission of any Acquisition Proposal, (ii) enter into or participate in any discussions or negotiations with, furnish any non-public information relating to the Company or any of its Subsidiaries or afford access to the business, properties, assets, books or records of the Company or any of its Subsidiaries to, otherwise cooperate in any way with, or knowingly assist, participate in, facilitate or encourage any effort by any Third Party, in each case, in connection with or in response to an Acquisition Proposal or an inquiry or indication of interest that could reasonably be expected to lead to an Acquisition Proposal, (iii) fail to make, withdraw or modify in a manner adverse to Parent the Company Board Recommendation (or recommend an Acquisition Proposal or make any statement inconsistent with the Company Board Recommendation) (any of the foregoing in this clause (iii), an “Adverse Recommendation Change”), (iv) fail to enforce or grant any waiver or release under any standstill or similar agreement with respect to any class of equity securities of the Company or any of its Subsidiaries unless the Board of Directors determines in good faith, after consultation with outside legal counsel, that the failure to take such action would be inconsistent with its fiduciary duties under Delaware Law; provided that Company shall not enforce and hereby waives any provision of any such agreement that would prohibit a Third Party from communicating confidentially an Acquisition Proposal to the Board of Directors, (v) approve any transaction under, or any Person becoming an “interested stockholder” under, Section 203 of Delaware Law or (vi) enter into any agreement in principle, letter of intent, term sheet, merger agreement, acquisition agreement, option agreement or other similar instrument relating to an Acquisition Proposal. It is agreed that any violation of the restrictions on the Company set forth in this Section by any Representative of the Company or any of its Subsidiaries shall be a breach of this Section by the Company.

(b) Exceptions. Notwithstanding ‎Section 7.03(a), at any time prior to the Acceptance Date:

(i) the Company, directly or indirectly through its Representatives, may (A) engage in negotiations or discussions with any Third Party and its Representatives that, subject to the Company’s compliance with ‎Section 7.03(a), has made after the date of this Agreement a bona fide, written Acquisition Proposal that the Board of Directors reasonably believes is or could reasonably be expected to lead to a Superior Proposal and (B) furnish to such Third Party or its Representatives non-public information relating to the Company or any of its Subsidiaries pursuant to a confidentiality agreement with such Third Party with terms not less favorable in the aggregate to the Company than those contained in the Confidentiality Agreement (it being understood that such confidentiality agreement need not contain a standstill provision); provided that all such information (to the extent that such information has not been previously provided or made available to Parent) is provided or made available to Parent, as the case may be, prior to or substantially concurrently with the time it is provided or made available to such Third Party; and

(ii) subject to compliance with Sections ‎7.03(a) and ‎7.03(d), the Board of Directors may make an Adverse Recommendation Change and terminate this Agreement pursuant to ‎Section 11.01(d)(i) (A) following receipt of a Superior Proposal or (B) in response to material events or changes in circumstances arising after the date hereof that were not known to the Company as of or prior to the date hereof,

in each case referred to in the foregoing clauses (i) and (ii) only if the Board of Directors determines in good faith, after consultation with outside legal counsel, that the failure to take such action would be inconsistent with its fiduciary duties under Delaware Law.

In addition, nothing contained herein shall prevent the Board of Directors from complying with Rule 14e-2(a) under the 1934 Act with regard to an Acquisition Proposal so long as any action taken or statement made to so comply is consistent with this ‎Section 7.03; provided that any such action taken or statement made that relates to an Acquisition Proposal shall be deemed to be an Adverse Recommendation Change unless the Board of Directors reaffirms the Company Board Recommendation in such statement or in connection with such action. It is understood and agreed that any factually accurate public statement by the Company that merely describes the Company’s receipt of an Acquisition Proposal and the operation of this Agreement with respect thereto and contains a “stop, look and listen” communication (including pursuant to Rule 14d-9(f) promulgated under the 0000 Xxx) shall not constitute an Adverse Recommendation Change.

(c) Required Notices. The Board of Directors shall not take any of the actions referred to in ‎Section 7.03(b) unless the Company shall have delivered to Parent a prior written notice advising Parent that it intends to take such action. In addition, the Company shall notify Parent promptly (but in no event later than 24 hours) after receipt by the Company (or any of its Representatives) of any Acquisition Proposal, any indication that a Third Party is considering making an Acquisition Proposal or any request for information relating to the Company or any of its Subsidiaries or for access to the business, properties, assets, books or records of the Company or any of its Subsidiaries by any Third Party in connection with or in response to an Acquisition Proposal or an inquiry or indication of interest that could reasonably be expected to lead to an Acquisition Proposal. The Company shall provide such notice orally and in writing and shall identify the Third Party making (except to the extent the Company is prohibited from disclosing such information under the terms of a confidentiality agreement in force on the date hereof (“Restricted Information”)) and, the terms and conditions of, any such Acquisition Proposal, indication or request. The Company shall keep Parent reasonably apprised on a prompt basis of any material developments or changes with respect to any of the terms and conditions of such Acquisition Proposal, indication or request and shall promptly (but in no event later than 24 hours after receipt) provide to Parent copies (redacted to exclude any Restricted Information) of all correspondence and written materials sent or provided to the Company or any of its Subsidiaries that describes any terms or conditions of any Acquisition Proposal (as well as written summaries of any oral communications addressing such matters).

(d) “Last Look”. Further, the Board of Directors shall not make an Adverse Recommendation Change pursuant to ‎Section 7.03(b)(ii)(A) (or terminate this Agreement pursuant to ‎Section 11.01(d)(i)), unless (i) if such Adverse Recommendation Change is to be taken in circumstances involving or relating to an Acquisition Proposal, such Acquisition Proposal constitutes a Superior Proposal, (ii) the Company promptly provides written notice to Parent at least four Business Days before taking such action, of its intention to do so, containing (A) in the case of any action intended to be taken in circumstances involving an Acquisition Proposal, the material terms of such Acquisition Proposal, including the most current version of the proposed agreement under which such Acquisition Proposal is proposed to be consummated and the identity of the Third Party making the Acquisition Proposal, or (B) in the case of any action intended to be taken in circumstances not involving an Acquisition Proposal, a reasonably detailed description of the underlying facts giving rise to, and the reasons for taking such action and (iii) Parent does not make, within four Business Days after its receipt of that written notification, an offer that (A) in the case of any action intended to be taken in circumstances involving an Acquisition, is at least as favorable to the stockholders of the Company as such Acquisition Proposal, taking into account all the terms and conditions of the Acquisition Proposal, including any break-up fees, expense reimbursement provisions and conditions to consummation (and expected timing of consummation relative to

that included in the proposal by Parent to amend the terms of this Agreement) (it being understood and agreed that any amendment to the financial terms or other material terms of such Acquisition Proposal shall require a new written notification from the Company under this ‎Section 7.03(d)) or (B) in the case of any action intended to be taken in circumstances not involving an Acquisition Proposal, obviates the need for taking such action. The Company agrees that, during any four-Business Day period referred to in this ‎Section 7.03(d), the Company and its Representatives shall negotiate in good faith with Parent and its Representatives (if Parent requests to so negotiate) regarding any revisions proposed by Parent to the terms of the transactions contemplated by this Agreement.

(e) Definition of Superior Proposal. For purposes of this Agreement, “Superior Proposal” means a bona fide, unsolicited written Acquisition Proposal (substituting the term “50%” for the term “30%” in each instance where such term appears in the definition thereof) that the Board of Directors determines in good faith by a majority vote, after considering the advice of a financial advisor of nationally recognized reputation and outside legal counsel and taking into account all the terms and conditions of the Acquisition Proposal, including any break-up fees, expense reimbursement provisions and conditions to consummation (and expected timing of consummation relative to the transactions contemplated by this Agreement), are more favorable the Company’s stockholders than as provided hereunder (taking into account any proposal by Parent to amend the terms of this Agreement pursuant to ‎Section 7.03(d)) and, if applicable, any proposed or contemplated future sale or sales of the remaining assets of the Company and its Subsidiaries.

(f) Obligation of the Company to Terminate Existing Discussions. The Company shall, and shall cause its Subsidiaries and its and their Representatives to, cease immediately and cause to be terminated any and all existing activities, discussions or negotiations, if any, with any Third Party and its Representatives conducted prior to the date hereof with respect to any Acquisition Proposal and shall request that any such Third Party (together with its Representatives) that has executed a confidentiality agreement within the 24-month period prior to the date hereof and that is in possession of confidential information heretofore furnished by or on behalf of the Company or any of its Subsidiaries (and all analyses and other materials prepared by or on behalf of such Person that contains, reflects or analyzes that information) to return or destroy all such information as promptly as practicable.

Section 7.04. Compensation Arrangements. Prior to the Acceptance Date, the Company (acting through its Compensation Committee) will take all steps that may be necessary or advisable to cause each Company Plan pursuant to which compensation is payable to any officer, director or employee to be approved by the Compensation Committee of the Board of Directors as an “employment compensation, severance or other employee benefit arrangement”

within the meaning of Rule 14d-10(d)(2) under the 1934 Act and to satisfy the requirements of the non-exclusive safe harbor set forth in Rule 14d-10(d) of the 1934 Act.

Section 7.05. Stock Exchange Delisting; 1934 Act Deregistration. Prior to the Effective Time, the Company shall cooperate with Parent and use its reasonable best efforts to take, or cause to be taken, all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under Applicable Law and rules and policies of Nasdaq and consistent with the terms of this Agreement to enable the delisting by the Surviving Corporation of the Shares from Nasdaq and the deregistration of the Shares under the 1934 Act as promptly as practicable after the Effective Time.

Section 7.06. Takeover Statutes. The Company shall, to the extent permitted by Applicable Law, use its reasonable best efforts (a) to take all actions necessary so that no “control share acquisition,” “fair price,” “moratorium” or other antitakeover or similar statute or regulation becomes applicable to the transactions contemplated by this Agreement and (b) if any such antitakeover or similar statute or regulation becomes applicable to the transactions contemplated by this Agreement, to take all actions necessary so that the transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated herein and otherwise to take all such other actions as are reasonably necessary to eliminate or minimize the effects of any such statute or regulation on the transactions contemplated hereby.

Section 7.07. Stockholder Litigation. From and after the date hereof, the Company shall promptly advise Parent orally and in writing of any actions, suits, claims or proceedings (including derivative claims) commenced or, to the knowledge of the Company, threatened in writing to the Company against the Company and/or its directors or executive officers relating to this Agreement, the Offer, the Merger and/or the other transactions contemplated hereby and shall keep Parent fully informed regarding any such action, suit, claim or proceeding. The Company shall give Parent the opportunity to consult with the Company regarding the defense or settlement of any such action, suit, claim or proceeding and shall give due consideration to Parent’s views with respect thereto. The Company shall not agree to any settlement of any such action, suit, claim or proceeding (including derivative claims) without Parent’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed.

Section 7.08. Section 16 Matters. Prior to the Effective Time, the Company shall take all such steps as may be required to cause any dispositions of Shares in connection with the Offer, the Merger or ‎Section 3.05 (including derivative securities of such Shares) by each individual who is subject to the reporting requirements of Section 16(a) of the 1934 Act with respect to the Company and will become subject to such reporting requirements with respect to Parent to be exempt under Rule 16b-3 promulgated under the 1934 Act.

Section 7.09. Part III Disclosure. If the Company omits information required to be disclosed pursuant to Part III of Form 10-K from its annual report on Form 10-K for the year ended December 31, 2014 because the Company intends to include such information in its proxy statement for its 2015 annual meeting and the Closing occurs before the filing of such proxy statement, the Company shall use its reasonable best efforts to ensure that the Company will be able to as promptly (and in any event within ten days) after the Closing file an amendment to its annual report on Form 10-K for the year ended December 31, 2014 that includes such Part III information.

Section 7.10. Company’s Auditors. From the date hereof until the Effective Time, the Company shall use its commercially reasonable efforts to cause the Company’s auditors to complete their audit for the year ending December 31, 2014 in a timely manner consistent with past practice and, at the reasonable request of Parent, to perform a review of the consolidated interim financial statements of the Company for any period beginning thereafter.

Section 7.11. Consultation as to Certain Tax Matters. Except as set forth in ‎Section 7.01 of the Company Disclosure Schedule, prior to xxiv) consummating any material transaction that (i) is described in clause ‎(b), ‎(c), ‎(i), or ‎(j) of ‎Section 7.01 and (ii) is not subject to Parent’s consent right provided in ‎Section 7.01 on the basis that such transaction involves solely the Company and one or more its Subsidiaries or solely its Subsidiaries, or xxv) altering any material intercompany arrangements or agreements or the ownership structure among the Company and its wholly owned Subsidiaries or among the Company’s wholly owned Subsidiaries, the Company shall consult with Parent reasonably prior to consummating any such transaction and shall not proceed with any such action or transaction described in clause ‎(a) or ‎(b) hereof without Parent’s consent (not to be unreasonably conditioned, withheld or delayed) if such action or transaction would, in the reasonable judgment of the Company, and without taking into account any action or transaction entered into by Parent or any of its Subsidiaries (including, after the Effective Time, the Company or any of its Subsidiaries), reasonably be expected to materially change the Tax position of the Company and its Subsidiaries.

ARTICLE 8

Covenants of Parent

Parent agrees that:

Section 8.01. Obligations of Merger Subsidiary. Parent shall take all action necessary to cause Merger Subsidiary to perform its obligations under this Agreement and to consummate the Offer and the Merger on the terms and conditions set forth in this Agreement.

Section 8.02. Director and Officer Liability. (a) Parent shall cause the Surviving Corporation, and the Surviving Corporation hereby agrees, to do the following:

(i) For six years after the Effective Time, indemnify and hold harmless the present and former officers and directors of the Company (each, an “Indemnified Person”) in respect of acts or omissions occurring at or prior to the Effective Time to the fullest extent permitted by Delaware Law or any other Applicable Law or provided under the Company’s certificate of incorporation and bylaws in effect on the date hereof; provided that such indemnification shall be subject to any limitation imposed from time to time under Applicable Law.

(ii) For six years after the Effective Time, maintain in effect provisions in the Surviving Corporation’s certificate of incorporation and bylaws (or in such documents of any successor to the business of the Surviving Corporation) regarding elimination of liability of directors, indemnification of officers, directors and employees and advancement of expenses that are no less advantageous to the intended beneficiaries than the corresponding provisions in existence on the date of this Agreement.

(iii) Either (A) continue to maintain in effect for six years after the Effective Time the Company’s directors’ and officers’ insurance policies and fiduciary liability insurance policies (collectively, “D&O Insurance”) in place as of the date hereof or (B) purchase comparable D&O Insurance for such six-year period, in each case with respect to any claim related to any period of time at or prior to the Effective Time with terms, conditions, retentions and limits of liability that are at least as favorable as those contained in the D&O Insurance in effect as of the date hereof; provided that in no event shall Parent or the Surviving Corporation be required to expend for such policies pursuant to this sentence an aggregate premium amount in excess of 300% of the amount per annum the Company paid in its last full fiscal year, which amount is set forth in ‎Section 8.02(a)(iii) of the Company Disclosure Schedule; and provided, further, that if the aggregate premiums of such insurance coverage exceed such amount, the Surviving Corporation shall be obligated to obtain a policy with the greatest coverage available, with respect to matters occurring prior to the Effective Time, for a cost not exceeding such amount. At the Company’s option, the Company may purchase, prior to the Effective Time, a six-year prepaid “tail policy” with terms, conditions, retentions and limits of liability that are at least as favorable as those contained in the D&O Insurance in effect as of the date hereof, in which event Parent shall cease to have any obligations under the first sentence of this ‎Section 8.02(a)(iii); provided that the aggregate premium for such policies shall not exceed 300% of the amount per annum the Company paid in its last full fiscal year. In the event the Company elects to

purchase such a “tail policy,” the Surviving Corporation shall (and Parent shall cause the Surviving Corporation to) maintain such “tail policy” in full force and effect and continue to honor their respective obligations thereunder.

(iv) If Parent, the Surviving Corporation or any of their respective successors or assigns (A) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (B) transfers or conveys all or substantially all of its properties and assets to any Person, then, and in each such case, to the extent necessary, make proper provision so that the successors and assigns of Parent or the Surviving Corporation, as the case may be, shall assume the obligations set forth in this ‎Section 8.02.

(b) The rights of each Indemnified Person under this ‎Section 8.02 shall be in addition to any rights such Indemnified Person may have under the certificate of incorporation or bylaws of the Company or any of its Subsidiaries, Delaware Law or any other Applicable Law or any agreement of any Indemnified Person with the Company or any of its Subsidiaries. These rights shall survive consummation of the Merger and are intended to benefit, and shall be enforceable by, each Indemnified Person.

Section 8.03. Employee Matters. (a) During the period beginning at the Effective Time and ending on December 31, 2015, Parent shall, or shall cause its Subsidiaries to, provide to each employee who is actively employed by the Company or its Subsidiaries at the Effective Time (each, a “Covered Employee”), (i) base salary or base wages and cash target bonus opportunity no less than the base salary or base wages and cash target bonus opportunity provided to such Covered Employee immediately prior to the Acceptance Date and (ii) benefits (other than equity compensation and other long-term incentives, change in control, retention, transition, stay or similar arrangements) that are substantially comparable in the aggregate to the benefits (other than equity compensation and other long-term incentives, change in control, retention, transition, stay or similar arrangements) as in effect immediately prior to the Acceptance Date.

(b) In the event any Covered Employee first becomes eligible to participate under any employee benefit plan, program, policy or arrangement of Parent or any of its Subsidiaries (each, a “Parent Plan”) following the Effective Time, Parent shall, or shall cause its Subsidiaries to use reasonable efforts to: (i) waive any preexisting condition exclusions and waiting periods with respect to participation and coverage requirements applicable to such Covered Employee under any Parent Plan providing medical, dental or vision benefits to the same extent such limitation would have been waived or satisfied under the Company Plan such Covered Employee participated in immediately prior to coverage under such Parent Plan and (ii) provide such Covered Employee with credit for any

copayments and deductibles paid under a Company Plan prior to such Covered Employee’s coverage under any Parent Plan during the calendar year in which such amount was paid, to the same extent such credit was given under the Company Plan such Covered Employee participated in immediately prior to coverage under such Parent Plan in satisfying any applicable deductible or out-of-pocket requirements under such Parent Plan. Parent shall, or shall cause the Surviving Corporation or Parent’s or the Surviving Corporation’s Subsidiaries, as applicable, to, give Covered Employees full credit for such Covered Employees’ service with the Company and its Subsidiaries for purposes of eligibility, vesting (other than for purposes of future equity grants), and determination of the level of paid time off, vacation and sick leave benefits, under any benefit plans of Parent, the Surviving Corporation or any of their respective Subsidiaries in which the Covered Employee participates to the same extent recognized by the Company immediately prior to the Acceptance Date; provided, however, that such service shall not be recognized to the extent that (i) such recognition would result in a duplication of benefits with respect to the same period of service or (ii) such service was not recognized under the corresponding Company Plan.

(c) Effective as of immediately prior to the Acceptance Date, unless otherwise directed in writing by Parent at least five Business Days prior to any scheduled expiration date of the Offer, the Company shall terminate the Company’s 401(k) Plan, pursuant to resolutions of the Board of Directors. Prior to adopting any such resolutions, the Company shall provide Parent with a reasonable opportunity to review such resolutions.

(d) Prior to the Acceptance Date, the Board of Directors or the appropriate committee thereof shall take all actions necessary, including adopting any resolutions or amendments and providing any notices to participants, with respect to the NPS Pharmaceuticals, Inc. 2010 Employee Stock Purchase Plan (the “ESPP”) to: (1) cause the Offering Period (as defined in the ESPP) ongoing as of the date of this Agreement to cease and be the final Offering Period under the ESPP and the options under the ESPP to be exercised on the earlier of (x) the scheduled purchase date for such Offering Period and (y) the date that is seven Business Days prior to the initial scheduled expiration date of the Offer (with any participant payroll deductions not applied to the purchase of shares of common stock of the Company returned to the participant), (2) prohibit any individual who is not participating in the ESPP as of the date of this Agreement from commencing participation in the ESPP following the date of this Agreement, (3) prohibit participants in the ESPP from increasing their payroll deductions from those in effect as of the date of this Agreement and (4) terminate the ESPP effective immediately prior to the Effective Time. Prior to providing notices to participants, the Company shall provide Parent with a reasonable opportunity to review such notices.

(e) From and after the Effective Time, Parent shall, and shall cause the Surviving Corporation to, honor and perform the obligations of the Company or

any Subsidiary under each Company Plan, including, without limitation, International Plans and the Company's Change in Control Severance Pay Plan, as amended and as provided to Parent as of the date of this Agreement, and each employment or other similar agreement to which the Company or a Subsidiary of the Company is a party.

(f) Nothing in this ‎‎Section 8.03, express or implied, (5) is intended to or shall confer upon any Person other than the parties hereto and their respective successors and assigns, including any current or former Service Provider, any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement, or (6) shall establish or constitute an amendment, termination or modification of, or an undertaking to establish, amend, terminate or modify, any benefit plan, program, agreement or arrangement, (7) shall alter or limit the ability of Parent or any of its Subsidiaries (or, following the Effective Time, the Surviving Corporation or any of its Subsidiaries) to amend, modify or terminate any benefit plan, program, agreement or arrangement at any time assumed, established, sponsored or maintained by any of them or (8) shall create any obligation on the part of Parent or its Subsidiaries (or, following the Effective Time, the Surviving Corporation or its Subsidiaries) to employ or engage any Service Provider for any period following the Effective Time.

ARTICLE 9

Covenants of Parent and the Company

The parties hereto agree that:

Section 9.01. Reasonable Best Efforts.

The Company (x) shall not take or agree to take any action identified in clause (A) or (B) of the preceding sentence (any such action, a “Burdensome Condition”) without the prior written consent of Parent and (y) if so requested by Parent, shall use reasonable best efforts to take any Burdensome Condition provided that such Burdensome Condition is conditioned on the consummation of the Offer and does not reduce the Offer Price or the Merger Consideration. Parent and Merger Subsidiary shall not take any action or agree to take any action (including by acquiring or agreeing to acquire by merging or consolidating with, or by purchasing a substantial portion of the assets of or equity in, or by any other manner, any business of any Third Party) which is reasonably likely to prevent the obtaining of, any authorization, consent, order, declaration or approval of any Governmental Authority, or expiration or termination of the applicable waiting period under, any Competition Law by the End Date or delay such obtaining, expiration or termination to a date after the End Date.

(b) In furtherance and not in limitation of the foregoing, each of Parent and the Company shall (i) make an appropriate filing of a Notification and Report Form pursuant to the HSR Act with respect to the transactions contemplated hereby as promptly as practicable, and in any event within ten Business Days after the date hereof, (ii) make appropriate Filings pursuant to any other Competition Law with respect to the transactions contemplated hereby as promptly as practicable after the date hereof and (iii) supply as promptly as practicable any additional information and documentary material that may be requested and to use their reasonable best efforts to take all other actions necessary to cause the expiration or termination of the applicable waiting periods under the HSR Act or such other Competition Law as soon as practicable.

(d) Each of the Company and Parent may, as each deems advisable and necessary, reasonably designate any competitively sensitive material provided to the other under this ‎Section 9.01 as “Outside Counsel Only Material.” Such materials and the information contained therein shall be given only to the outside counsel of the recipient and, subject to any additional confidentiality or joint defense agreement the parties may mutually propose and enter into, will not be disclosed by such outside counsel to employees, officers or directors of the recipient unless express permission is obtained in advance from the source of the

materials (the Company or Parent, as the case may be) or its legal counsel. Notwithstanding anything to the contrary in this ‎Section 9.01, materials provided to the other party or its outside counsel may be redacted (i) to remove references concerning valuation, (ii) as necessary to comply with contractual arrangements and (iii) as necessary to address reasonable attorney-client or other privilege or confidentiality concerns.

(e) The Company and Parent shall cooperate with one another in determining whether any action by or in respect of, or Filing with, any Governmental Authority is required, or any actions, consents, approvals or waivers are required to be obtained from parties to any Contracts, in connection with the consummation of the transactions contemplated by this Agreement.

(d) by the Company, if, prior to the Acceptance Date:

(i) the Board of Directors shall have made an Adverse Recommendation Change in compliance with the terms of this Agreement, including ‎Section 7.03(d), and such termination is effected in order to enter into a definitive, written agreement immediately following such termination in respect of a Superior Proposal; provided that such termination may not occur unless the Company shall have paid or have had paid on its behalf the Termination Fee immediately before and as a condition to such termination; or

(ii) a breach of any representation or warranty or failure to perform any covenant or agreement on the part of Parent or Merger Subsidiary set forth in this Agreement shall have occurred and such breach or failure (c) is incapable of being cured by the End Date or, if curable by the End Date, is not cured by Parent or Merger Subsidiary within 30 days of receipt by Parent of written notice of such breach or failure and (d) would reasonably be expected to have, individually or in the aggregate, a Parent Material Adverse Effect; provided that, the right to terminate this Agreement pursuant to this Section 11.01(d)(ii) shall not be available to the Company if the Company shall then be in material breach of its obligations under this Agreement.

Section 11.02. Effect of Termination. If this Agreement is terminated pursuant to ‎Section 11.01, this Agreement shall become void and of no effect without liability of any party (or any stockholder or Representative of such party) to the other party hereto; provided that, if such termination shall result from (3) the fraud of either party or (4) the intentional and willful failure of either party (a) to fulfill a condition to the performance of the obligations of the other party or (b) to perform a covenant hereof, such party shall be fully liable for any and all liabilities and damages incurred or suffered by the other party as a result of such failure. The provisions of this ‎Section 11.02 and Sections ‎12.01, ‎12.04, ‎12.07, ‎12.08, ‎12.09 and ‎Section 12.14 shall survive any termination hereof pursuant to ‎Section 11.01.

Section 12.02. Survival of Representations and Warranties. The representations and warranties contained herein and in any certificate or other writing delivered pursuant hereto shall not survive the Effective Time.

Section 12.03. Amendments and Waivers. (a) Any provision of this Agreement may be amended or waived prior to the Effective Time if, but only if, such amendment or waiver is in writing and is signed, in the case of an amendment, by each party to this Agreement or, in the case of a waiver, by each party against whom the waiver is to be effective; provided that after the Acceptance Date no amendment shall be made that decreases the Offer Price or the Merger Consideration or otherwise adversely affect the rights of the Company’s stockholders (other than Parent or its Affiliates) hereunder without the approval of such stockholders.

(b) No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

Section 12.04. Expenses. (a) General. Except as otherwise provided herein, all costs and expenses incurred in connection with this Agreement shall be paid by the party incurring such cost or expense.

(b) Termination Fee. (1) If this Agreement is terminated by Parent pursuant to ‎Section 11.01(c)(i) or by the Company pursuant to ‎Section 11.01(d)(i), then the Company shall pay to Parent, to be received and held by Parent in trust for one or more Affiliates of Parent designated by Parent in writing prior to the receipt of such payment (each such Affiliate, a “Designated Affiliate”), or to one or more such Designated Affiliates directly, in immediately available funds $155,939,696 (the “Termination Fee”), in the case of a termination by Parent, within one Business Day after such termination and, in the case of a termination by the Company, immediately before and as a condition to such termination.

(ii) If (a) this Agreement is terminated by Parent or the Company pursuant to ‎Section 11.01(b)(i) or by Parent pursuant to ‎Section 11.01(c)(ii) or ‎Section 11.01(b)(iii), (b) after the date of this Agreement and prior to such termination, an Acquisition Proposal shall have been publicly announced or otherwise communicated to the Board of Directors or the Company’s stockholders and (c) within 12 months following the date of such termination, the Company shall have entered into a definitive agreement with respect to or recommended to its stockholders an Acquisition Proposal or any Acquisition Proposal shall have been consummated (provided that for purposes of this clause ‎(C), each reference to “30%” in the definition of Acquisition Proposal shall be deemed to be a reference to “50%”), then the Company shall pay to Parent to be received and held by Parent in trust for one or more Designated Affiliates, or to one or more such Designated Affiliates directly, in immediately available funds, concurrently with the occurrence of the applicable event described in clause ‎(C), the Termination Fee.

(iii) In no event shall the Company or any Person on the Company’s behalf be required to pay the Termination Fee on more than one occasion, whether or not the Termination Fee may be payable at different times or upon the occurrence of different events. Other than in the case of the fraud by the Company or the intentional and willful failure of the Company to fulfill a condition to the performance of the obligations of Parent or Merger Subsidiary, in circumstances where the Termination Fee is payable in accordance with this ‎Section 12.04(b), Parent’s receipt of the Termination Fee from or on behalf of the Company shall be deemed to be liquidated damages and not a penalty and shall be Parent’s and Merger Subsidiary’s sole and exclusive remedy under this Agreement, and the

Company, and any Person who pays the Termination Fee on the Company’s behalf, shall have no further liability to Parent or Merger Subsidiary with respect to this Agreement and the transactions contemplated hereby or the termination hereof.

(c) Other Costs and Expenses. The Company acknowledges that the agreements contained in this ‎Section 12.04 are an integral part of the transactions contemplated by this Agreement and that, without these agreements, Parent and Merger Subsidiary would not enter into this Agreement. Accordingly, if the Company fails promptly to pay any amount due to Parent pursuant to this ‎Section 12.04, it shall also pay any costs and expenses incurred by Parent and its Affiliates in connection with a legal action to enforce this Agreement that results in a judgment against the Company for such amount, together with interest on the amount of any unpaid fee, cost or expense at the publicly announced prime rate of Citibank, N.A. from the date such fee, cost or expense was required to be paid to (but excluding) the payment date; provided that, in the case the Company contests in good faith any amount due to Parent pursuant to this ‎Section 12.04, (i) the costs and expenses incurred by Parent and its Affiliates in connection such legal action shall not be borne by the Company and (ii) interest on the amount of any unpaid fee shall not accrue until the final disposition of such legal action.

Section 12.05. Disclosure Schedule and SEC Document References. (a) The parties hereto agree that any reference in a particular Section of the Company Disclosure Schedule shall only be deemed to be an exception to (or, as applicable, a disclosure for purposes of) the representations and warranties (or covenants, as applicable) of the relevant party that are contained in the corresponding Section of this Agreement and any other representations and warranties of such party that are contained in this Agreement, but only if the relevance of that reference as an exception to (or a disclosure for purposes of) such representations and warranties would be readily apparent to a reasonable person engaged in the business of the Parent and its Subsidiaries who has read that reference and such representations and warranties, without any independent knowledge on the part of the reader regarding the matter(s) so disclosed.

(b) The parties hereto agree that any information contained in any Company SEC Document listed in the first sentence of ‎‎Article 5 shall only be deemed to be an exception to (or, as applicable, a disclosure for purposes of) the Company’s representations and warranties if the relevance of that information as an exception to (or a disclosure for purposes of) such representations and warranties would be reasonably apparent to a reasonable person engaged in the business of the Parent and its Subsidiaries who has read that information concurrently with such representations and warranties, without any independent knowledge on the part of the reader regarding the matter(s) so disclosed; provided that in no event shall any information contained in any part of any Company SEC Document under the headings “Safe Harbor Statement” or “Risk Factors,”

containing a description or explanation of “Forward-Looking Statements” or any similar section, or that is predictive, cautionary or forward-looking in nature, be deemed to be an exception to (or, as applicable, a disclosure for purposes of) any representations and warranties of the Company contained in this Agreement.

Section 12.06. Binding Effect; Benefit; Assignment. (a) The provisions of this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and assigns. Except (i) as provided in ‎Section 8.02 (which is intended for the benefit of the Indemnified Persons, all of whom shall be third party beneficiaries thereof) (ii) for (A) the rights of the Company’s stockholders to receive the Offer Price in accordance with the Offer and, following the Acceptance Date, the Merger Consideration and the holders of the Company Stock Options and Company Stock Units to receive the consideration described in ‎Section 3.05, and (B) the right of the Company, on behalf of its stockholders and the holders of the Company Stock Options and Company Stock Units to pursue specific performance as set forth in ‎Section 12.13 or, if specific performance is not sought or is not granted as a remedy, damages, to the extent proven (which damages the parties agree may be based upon the consideration that would have otherwise been payable to holders, lost premium and any decrease in value of Shares, Company Stock Options and Company Stock Units, as applicable) in the event of Parent’s or Merger Subsidiary’s intentional and willful failure to perform a covenant or agreement hereof, which rights of the Company’s stockholders and the Company are hereby acknowledged and agreed by Parent and Merger Subsidiary, no provision of this Agreement is intended to confer any rights, benefits, remedies, obligations or liabilities hereunder upon any Person other than the parties hereto and their respective successors and permitted assigns.

(b) No party may assign, delegate or otherwise transfer any of its rights or obligations under this Agreement without the consent of each other party hereto, except that Parent or Merger Subsidiary may transfer or assign its rights and obligations under this Agreement, in whole or from time to time in part, to one or more of its Affiliates at any time and, after the Effective Time, to any Person; provided that such transfer or assignment shall not relieve Parent or Merger Subsidiary of its obligations hereunder or enlarge, alter or change any obligation of any other party hereto or prejudice the rights of tendering stockholders to receive payment for Shares validly tendered and accepted for payment pursuant to the Offer.

Section 12.07. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to the conflicts of law rules of such state.

Section 12.08. Jurisdiction. The parties hereto agree that any suit, action or proceeding seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the transactions

contemplated hereby (whether brought by any party or any of its Affiliates or against any party or any of its Affiliates) shall be brought in the Delaware Chancery Court or, if such court shall not have jurisdiction, any federal court located in the State of Delaware or other Delaware state court, and each of the parties hereby irrevocably consents to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such suit, action or proceeding and irrevocably waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding in any such court or that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. Process in any such suit, action or proceeding may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing, each party agrees that service of process on such party as provided in ‎Section 12.01 shall be deemed effective service of process on such party.

Section 12.09. WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

Section 12.10. Counterparts; Effectiveness. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement shall become effective when each party hereto shall have received a counterpart hereof signed by all of the other parties hereto. Until and unless each party has received a counterpart hereof signed by the other party hereto, this Agreement shall have no effect and no party shall have any right or obligation hereunder (whether by virtue of any other oral or written agreement or other communication).

Section 12.11. Entire Agreement. This Agreement and the Confidentiality Agreement constitute the entire agreement between the parties with respect to the subject matter of this Agreement and supersede all prior agreements and understandings, both oral and written, between the parties with respect to the subject matter of this Agreement.

Section 12.12. Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other Governmental Authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such a determination, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as

closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Section 12.13. Specific Performance. The parties hereto agree that irreparable damage would occur if any provision of this Agreement were not performed in accordance with the terms hereof and that, except where this Agreement is terminated in accordance with ‎Section 11.01, the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof in the courts referred to in ‎Section 12.08, without proof of actual damages (and each party further agrees to waive any requirement for the securing or posting of any bond in connection with such remedy), in addition to any other remedy to which they are entitled at law or in equity.

(a) Parent Holdco irrevocably and unconditionally guarantees to the Company the due and punctual performance of the obligations of Parent and Merger Subsidiary hereunder (the “Guaranteed Obligations”) subject to the terms hereof. If, for any reason whatsoever, Parent or Merger Subsidiary shall fail or be unable to duly, punctually and fully pay or perform the Guaranteed Obligations, Parent Holdco will forthwith pay or perform, or cause to be paid or performed, the Guaranteed Obligations.

This is a guarantee of payment and performance and not collectability.

(b) Parent Holdco is a legal entity duly organized, validly existing and (to the extent applicable) in good standing under the laws of its jurisdiction of organization. Parent Holdco has all requisite corporate power and authority and has taken all corporate action necessary in order to execute, deliver and perform its obligations under this Agreement.
