Prior to the Offer Closing Time, Parent shall not, except with the prior written consent of the Company, require the Company to make any payment with respect to any demands for appraisal or offer to settle or settle any such demands.

SECTION 3.09 Payment of Merger Consideration.

(a) Paying Agent. Prior to the Effective Time, Parent shall select a bank or trust company reasonably acceptable to the Company to act as paying agent (the “Paying Agent”) for the payment of the Merger Consideration to former holders of Company Common Stock. Parent shall, or shall cause the Surviving Corporation to, deposit with the Paying Agent, as and when necessary after the Effective Time, cash sufficient to pay the Merger Consideration in respect of the shares of Company Common Stock and Company Warrants converted into the right to receive cash pursuant to Section 3.08(c) and Section 3.11, respectively (such cash being hereinafter referred to as the “Payment Fund”).

16

(b) Payment Procedure. As promptly as reasonably practicable (but in no event later than two Business Days) after the Effective Time, the Surviving Corporation or Parent shall cause the Paying Agent to mail to each holder of record of a certificate or certificates that, immediately prior to the Effective Time, represented outstanding shares of Company Common Stock (the “Certificates”) that were converted into the right to receive the Merger Consideration pursuant to Section 3.08 (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Paying Agent, and shall be in such form and have such other provisions as are customary and reasonably acceptable to the Company and Parent) and (ii) instructions for effecting the surrender of the Certificates in exchange for the Merger Consideration. Upon surrender of a Certificate to the Paying Agent for cancelation, together with such letter of transmittal, duly executed and in proper form, and such other documents as may reasonably be required by the Paying Agent, the holder of such Certificate shall be entitled to receive, in exchange therefor, the Merger Consideration for each share of Company Common Stock theretofore represented by such Certificate pursuant to Section 3.08, and the Certificate so surrendered shall forthwith be canceled. In the event of a transfer of ownership of Company Common Stock that is not registered in the transfer records of the Company, payment may be made to a Person other than the Person in whose name the Certificate so surrendered is registered, if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such payment shall pay any transfer or other Taxes required by reason of the payment to a Person other than the registered holder of such Certificate or establish to the satisfaction of Parent that such Tax has been paid or is not applicable. None of Parent, Merger Sub or the Surviving Corporation shall have any liability for the transfer and other similar Taxes described in this Section 3.09(b) under any circumstances. Until surrendered as contemplated by this Section 3.09, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the amount of cash, without interest, into which the shares of Company Common Stock theretofore represented by such Certificate have been converted pursuant to Section 3.08. No interest shall be paid or accrue on the cash payable upon surrender of any Certificate.

(c) Treatment of Book-Entry Shares. No holder of record of Book-Entry Shares shall be required to deliver a Certificate or a letter of transmittal to the Paying Agent to receive the Merger Consideration in respect of such Book-Entry Shares. In lieu thereof, such holder of record shall, upon receipt by the Paying Agent of an “agent’s message” in customary form (or such other evidence, if any, as the Paying Agent may reasonably request), be entitled to receive, and the Surviving Corporation or Parent shall cause the Paying Agent to pay and deliver as promptly as reasonably practicable after the Effective Time (but in no event later than two Business Days after the Effective Time to each such holder of record as of the Effective Time), the Merger Consideration, less any applicable tax withholding, per Book-Entry Share to which such holder is entitled hereunder, and such Book-Entry Shares shall forthwith be canceled. Payment of the Merger Consideration with respect to Book-Entry Shares shall only be made to the Person in whose name such Book-Entry Shares are registered.

(d) Adjustments. If, between the Agreement Date and the Effective Time, the outstanding shares of Company Common Stock are changed into a different number or class of shares by reason of any stock split, division or subdivision of shares, stock dividend, reverse stock split, consolidation of shares, reclassification, recapitalization or other similar transaction, then the Merger Consideration shall be appropriately adjusted.

(e) No Further Ownership Rights in Company Common Stock. The Merger Consideration paid in accordance with the terms of this Article III as a result of the conversion of any shares of Company Common Stock shall be deemed to have been paid in full satisfaction of all rights pertaining to such shares of Company Common Stock. After the Effective Time there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of shares of Company Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, any Certificates are presented to the Surviving Corporation or the Paying Agent for any reason, such Certificates shall be canceled and exchanged as provided in this Article III.

17

(f) Lost, Stolen or Destroyed Certificates. Notwithstanding the requirements to surrender a Certificate contained in Section 3.09, 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 such reasonable amount as Parent may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent will pay, in exchange for the shares of Company Common Stock formerly represented by such lost, stolen or destroyed Certificate, the applicable Merger Consideration to be paid in respect of such shares, less any applicable Tax withholding.

(g) Termination of Payment Fund. Any portion of the Payment Fund (and any interest or other income earned thereon) that remains undistributed as of the 12-month anniversary of the Merger Closing Date shall be delivered to Parent or its designated Affiliate, upon demand, and any former holder of Company Common Stock entitled to payment of Merger Consideration who has not theretofore complied with this Article III shall thereafter look only to Parent or any successor-in-interest of Parent for payment of its claim for Merger Consideration (subject to applicable abandoned property, escheat and other similar Law).

(h) No Liability. None of Parent, Merger Sub, the Company, the Surviving Corporation and the Paying Agent shall be liable to any Person in respect of any cash from the Payment Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If any Certificate has not been surrendered prior to the date on which the Merger Consideration in respect of such Certificate would otherwise escheat to or become the property of any Governmental Entity, any such Merger Consideration in respect of such Certificate shall, to the extent permitted by applicable Law, immediately prior to such date become the property of the Surviving Corporation or its designated Affiliate, free and clear of any claims or interest of any such holders or their successors, assigns or personal representative previously entitled thereto, subject to the claims of any former holder of Company Common Stock entitled to payment of Merger Consideration who has not theretofore complied with this Article III.

(i) Investment of Payment Fund. The Payment Fund shall be invested by the Paying Agent as directed by Parent. Nothing contained in this Section 3.09(i) and no investment losses resulting from the investment of the Payment Fund shall diminish the rights of the stockholders of the Company to receive the Merger Consideration. To the extent there are losses or the Payment Fund for any reason (including Appraisal Shares losing their status as such) is less than the level required to promptly pay the Merger Consideration pursuant to Section 3.08(c), Parent shall replace, restore or add to the cash in the Payment Fund to ensure the prompt payment of the Merger Consideration. Any interest and other income resulting from such investments shall be the property of, and paid to, Parent or its designated Affiliate.

(j) Withholding Rights. Each of the Company, the Surviving Corporation, Parent and the Paying Agent shall be entitled to deduct and withhold from the amounts otherwise payable to any former holder of Company Common Stock, Company Stock Options, Company RSUs or Company Warrants pursuant to this Agreement or the Offer such amounts as are required to be deducted and withheld with respect to the making of such payment under the Code, or under any provision of state, local or foreign Tax Law. Amounts so deducted or withheld and paid over to the appropriate Tax Authority shall be treated for all purposes of this Agreement as having been paid to the former holder of Company Common Stock, Company Stock Options, Company RSUs or Company Warrants in respect of whom such deduction or withholding was made. Parent shall use commercially reasonable efforts to cooperate with the payee to mitigate and reduce such withholding to the extent permitted by applicable Tax Law.

SECTION 3.10 Equity Awards.

(a) As of immediately prior to the Effective Time, each Company Stock Option that is then outstanding but not then vested or exercisable shall become immediately vested and exercisable in full. At the Effective Time, each Company Stock Option that is then outstanding shall be canceled and, if such Company Stock Option has a per share exercise price less than the Merger Consideration, the holder thereof shall be entitled to receive, with respect to each share of Company Common Stock underlying such Company Stock Option, an amount in cash equal to the excess, if any, of the Merger Consideration over the exercise price per share of Company Common Stock underlying such Company Stock Option, without interest and less any applicable Tax withholding (the “Company Stock Option Consideration”). Any Company Stock Option that has an exercise price that equals or exceeds the Merger Consideration shall be canceled for no consideration. Parent shall cause the Surviving Corporation to pay the Company Stock Option Consideration at or reasonably promptly after the Effective Time (but in no event later than ten Business Days after the Effective Time).

(b) As of immediately prior to the Effective Time, each Company RSU that is then outstanding but not then vested shall become immediately vested in full. At the Effective Time, each Company RSU that is then outstanding shall be canceled and the holder thereof shall be entitled to receive, with respect to each share of Company Common Stock underlying such Company RSU, an amount in cash equal to the Merger Consideration, without interest and less any applicable Tax withholding (the “Company RSU Consideration”). Parent shall cause the Surviving Corporation to pay the Company RSU Consideration at or reasonably promptly after the Effective Time (but in no event later than ten Business Days after the Effective Time).

(c) As soon as practicable following the Agreement Date, the Company shall take all actions with respect to the Company ESPP that are necessary to provide that (i) no new offering period shall be commenced under the Company ESPP prior to the Effective Time and (ii) immediately prior to the Effective Time, the Company ESPP shall terminate.

(d) Prior to the Effective Time, the Company Board (or, if appropriate, any committee thereof administering any Company Stock Plan, non-plan inducement award or the Company ESPP) shall adopt such resolutions or take such action by written consent in lieu of a meeting, providing for the transactions contemplated by this Section 3.10. The Company shall provide that, on and following the Effective Time, no holder of any Company Stock Option or Company RSU or non-plan inducement award shall have the right to acquire any equity interest in the Company or the Surviving Corporation in respect thereof and each Company Stock Plan shall terminate as of the Effective Time.

SECTION 3.11 Company Warrants.

(a) Pre-Funded Warrants. Each Pre-Funded Warrant that is outstanding as of immediately prior to the Effective Time will, upon the Effective Time, in accordance with Section 9(c) of such Pre-Funded Warrant, become exercisable by the holder thereof solely for the same Merger Consideration as such holder would have been entitled to receive following the Effective Time pursuant to Section 3.08 if such holder had been, immediately prior to the Effective Time, the holder of the number of shares of Company Common Stock then issuable upon exercise in full of such Pre-Funded Warrant without regard to any limitations on exercise contained therein. For the avoidance of doubt, any Pre-Funded Warrant that is exercised prior to the Effective Time shall be an outstanding share of Company Common Stock and treated in accordance with Section 3.08 (unless such share of Company Common Stock was purchased in the Offer).

19

(b) Other Company Warrants. To the extent the Company Warrants that are not a Pre-Funded Warrant (the “Other Company Warrants”) remain outstanding as of immediately prior to the Offer Closing Time, (i) any portion of the Other Company Warrants that then remains unexercised shall, in accordance with Section 1.6 of the Other Company Warrants, be exercised automatically in whole (and not in part) as of immediately prior to, and contingent upon, the Offer Closing Time (without any further action by the holder thereof) pursuant to the net exercise provisions set forth in Section 1.6 and Section 1.2 of the Other Company Warrants, and each share of Company Common Stock issuable pursuant to such automatic exercise of the Other Company Warrants (each, a “Warrant Share”) shall be issued by the Company to the holder of the Other Company Warrants and be outstanding as of immediately prior to the Effective Time, and treated identically to the other shares of Company Common Stock outstanding immediately prior to the Effective Time in accordance with the terms of this Agreement; provided that, for the avoidance of doubt, nothing in this Agreement shall entitle the holder of the Other Company Warrants to receive any consideration or payment in respect of the Other Company Warrants or any Warrant Share other than the Merger Consideration payable with respect to such Warrant Shares pursuant to Section 3.08, less any applicable Tax withholding.

(c) Certain Actions in Respect of Company Warrants. Following the Agreement Date and prior to the Effective Time, (i) the Company shall comply with all of its obligations under the Company Warrants and shall take all such actions as may be required to effect the treatment of the Company Warrants described in this Section 3.11, including delivering in a timely manner under the terms of each Pre-Funded Warrant the notices contemplated by Section 9(g) of each Pre-Funded Warrant and Section 3.2 of each Other Company Warrant, (ii) the Company shall promptly notify Parent if any holder of any Company Warrant elects to exercise such Company Warrant; (iii) the Company shall not amend, supplement or modify any of the terms of any Company Warrant without the prior written consent of Parent; and (iv) the Company shall use commercially reasonable efforts to cause each holder of a Pre-Funded Warrant to exercise such Pre-Funded Warrant prior to the expiration of the Offer.

SECTION 3.12 Further Action. If, at any time after the Effective Time, any further action is reasonably determined by Parent to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full right, title and possession of and to all rights and property of Merger Sub and the Company, the officers and directors of the Surviving Corporation and Parent shall be fully authorized (in the name of Merger Sub, in the name of the Company and otherwise) to take such action.

SECTION 6.02 No Solicitation.

(a) The Company and the Company Subsidiaries shall not, and shall cause its Representatives not to, (i) directly or indirectly solicit, initiate or knowingly encourage or knowingly facilitate (including by way of providing information) any inquiries, proposals or offers, or the making of any submission or announcement of any inquiry, proposal or offer that constitutes or would reasonably be expected to lead to a Company Takeover Proposal or (ii) directly or indirectly engage in, enter into or participate in any discussions or negotiations with any Person regarding, furnish to any Person any information or afford access to the business, properties, assets, books or records of the Company to, or take any other action to assist or knowingly facilitate or knowingly encourage any effort by any Person, in each case, in connection with or in response to any inquiry, offer or proposal that constitutes, or would reasonably be expected to lead to, any Company Takeover Proposal (other than, solely in response to an inquiry that did not result from a breach of this Section 6.02(a), to refer the inquiring person to this Section 6.02 and to limit its communication exclusively to such referral). The Company shall, and shall cause its Representatives to, immediately (i) cease all solicitations, discussions and negotiations regarding any inquiry, proposal or offer pending on the Agreement Date that constitutes, or would reasonably be expected to lead to, a Company Takeover Proposal, (ii) request the prompt return or destruction of all confidential information previously furnished to any Person within the last 12 months for the purposes of evaluating a possible Company Takeover Proposal and (iii) terminate access to any physical or electronic data rooms relating to a potential Company Takeover Proposal. Notwithstanding anything to the contrary contained in the foregoing or any other provision of this Agreement, at any time during the Pre-Closing Period, in response to a Company Takeover Proposal made after the Agreement Date that did not result from a breach of this Section 6.02(a), in the event that the Company Board determines, in good faith, after consultation with outside counsel and a financial advisor, that such Company Takeover Proposal constitutes or would reasonably be expected to lead to a Superior Company Proposal (a “Qualifying Company Takeover Proposal”), the Company may (A) enter into an Acceptable Confidentiality Agreement with any Person or group of Persons making such Qualifying Company Takeover Proposal, (B) furnish information with respect to the Company to the Person or group of Persons making such Qualifying Company Takeover Proposal and its or their Representatives pursuant to an Acceptable Confidentiality Agreement so long as the Company concurrently or promptly thereafter provides Parent, in accordance with the terms of the Confidentiality Agreement, any material non-public information with respect to the Company furnished to such other Person or group of Persons that was not previously furnished to Parent and (C) participate in discussions or negotiations with such Person or group of Persons and its or their Representatives regarding such Qualifying Company Takeover Proposal (including soliciting the making of a revised Qualifying Company Takeover Proposal); provided that the Company may only take the actions described in clauses (A), (B) or (C) above if the Company Board determines, in good faith, after consultation with outside counsel, that the failure to take any such action would be inconsistent with its fiduciary duties under applicable Law. Wherever the term “group” is used in this Section 6.02(a), it is used as defined in Rule 13d-5 under the Exchange Act.

(b) Neither the Company Board nor any committee thereof shall (i) (A) withdraw, qualify or modify in a manner adverse to Parent or Merger Sub, or propose publicly to withdraw, qualify or modify in a manner adverse to Parent or Merger Sub, the Company Board Recommendation or resolve or agree to take any such action, (B) adopt, endorse, approve or recommend, or propose publicly to adopt, endorse, approve or recommend, any Company Takeover Proposal or resolve or agree to take any such action, (C) publicly make any recommendation in connection with a tender offer or exchange offer (other than the Offer) other than a recommendation against such offer or (D) fail to include the Company Board Recommendation in the Schedule 14D-9 when disseminated to the Company’s stockholders (any action described in this clause (i) being referred to in this Agreement as an “Adverse Recommendation Change”) or (ii) approve or recommend, or publicly propose to approve or recommend, or authorize, cause or permit the Company to enter into any letter of intent, memorandum of understanding, agreement in principle,

48

acquisition agreement, option agreement, merger agreement, joint venture agreement, partnership agreement or other agreement relating to or that would reasonably be expected to lead to, any Company Takeover Proposal (other than an Acceptable Confidentiality Agreement entered into in accordance with Section 6.02(a)), or resolve, agree or publicly propose to take any such action. Notwithstanding anything to contrary in the foregoing or any other provision of this Agreement, (x) the Company Board may, in response to an Intervening Event, take any of the actions specified in clause (A) or (D) of the definition of Adverse Recommendation Change (an “Intervening Event Adverse Recommendation Change”) if the Company Board determines, in good faith, after consultation with outside counsel, that the failure to take such action would be inconsistent with its fiduciary duties under applicable Law and (y) if the Company Board receives a Superior Company Proposal that did not result from a breach of this Section 6.02, the Company may make an Adverse Recommendation Change, and may terminate this Agreement pursuant to Section 9.01(g) in order to enter into a definitive agreement with respect to the Superior Company Proposal; provided that, prior to so making an Intervening Event Adverse Recommendation Change or an Adverse Recommendation Change, or so terminating this Agreement pursuant to Section 9.01(g), (1) the Company Board shall have given Parent at least four Business Days’ prior written notice (a “Company Notice”) of its intention to take such action and a description of the reasons for taking such action (which Company Notice, in respect of a Superior Company Proposal, shall specify the identity of the Person who made such Superior Company Proposal and the material terms and conditions of such Superior Company Proposal and attach the most current version of the relevant transaction agreement or, in respect of an Intervening Event, shall include a reasonably detailed description of the underlying facts giving rise to such action), (2) the Company shall have negotiated, and shall have caused its Representatives to negotiate, in good faith, with Parent during such notice period, to the extent Parent wishes to negotiate, to enable Parent to revise the terms of this Agreement in such a manner that would eliminate the need for taking such action (and, in respect of a Superior Company Proposal, would cause such Superior Company Proposal to no longer constitute a Superior Company Proposal), (3) following the end of such notice period, the Company Board shall have considered in good faith any revisions to this Agreement irrevocably committed to in writing by Parent, and shall have determined in good faith, after consultation with outside counsel, that failure to effect such Adverse Recommendation Change or Intervening Event Adverse Recommendation Change would be inconsistent with its fiduciary duties under applicable Law and, with respect to a Superior Company Proposal, that such Superior Company Proposal continues to constitute a Superior Company Proposal and (4) in the event of any change to any of the financial terms (including the form and amount of consideration) of such Superior Company Proposal, the Company shall, in each case, deliver to Parent an additional Company Notice consistent with that described in clause (1) of this proviso and a renewed notice period under clause (1) of this proviso shall commence (except that the four-Business Day notice period referred to in clause (1) of this proviso shall instead be equal to two Business Days) during which time the Company shall be required to comply with the requirements of this Section 6.02(b) anew with respect to such additional Company Notice, including clauses (1) through (4) of this proviso.

(c) Nothing contained in this Section 6.02 or elsewhere in this Agreement shall prohibit the Company from (i) taking and disclosing to its stockholders a position contemplated by Rule 14d-9 or Rule 14e-2(a) promulgated under the Exchange Act (or any similar communication to stockholders), including making any “stop-look-and-listen” communication to the stockholders of the Company or (ii) making any disclosure to its stockholders if the Company Board determines, in good faith, after consultation with outside counsel, that the failure to take such action would reasonably be expected to be inconsistent with its fiduciary duties or applicable Law; provided that any such action that would otherwise constitute an Adverse Recommendation Change shall be made only in compliance with Section 6.02(b) (it being understood that: (A) any “stop, look and listen” letter or similar communication limited to the information described in Rule 14d-9(f) under the Exchange Act and (B) any disclosure of information to the Company’s stockholders that describes the Company’s receipt of a Company Takeover Proposal and the operation of this Agreement with respect thereto and contains a statement that the Company Board has not effected an Adverse Recommendation Change shall be deemed to not be an Adverse Recommendation Change).

49

(d) In addition to the requirements set forth in paragraphs (a) and (b) of this Section 6.02, the Company shall, as promptly as reasonably practicable and in any event within one Business Day after receipt thereof, advise Parent in writing of (i) any Company Takeover Proposal or any request for information or inquiry, proposal or offer that the Company Board in good faith believes would reasonably be expected to lead to a Company Takeover Proposal and (ii) the material terms and conditions of such Company Takeover Proposal or inquiry, proposal or offer (including, if applicable, copies of any written requests, proposals or offers, including proposed term sheets and agreements relating thereto, any subsequent amendments or modifications thereto) and the identity of the Person making any such Company Takeover Proposal or inquiry, proposal or offer. Commencing upon the provision of any notice referred to in the previous sentence, the Company and its Representatives shall keep Parent informed on a reasonably prompt basis as to any material developments with respect to any such Company Takeover Proposal or inquiry, proposal or offer (and any subsequent material amendments or modifications thereto), and shall provide Parent with a copy of any written correspondence, documents or agreements delivered to or by the Company or its Representatives that contain any material amendments thereto or any material change to the scope or material terms or conditions thereof (or, if not delivered in writing, a summary of any such material amendments or material changes).

ARTICLE VII

ADDITIONAL AGREEMENTS

SECTION 7.01 Access to Information; Confidentiality. Except if prohibited by any applicable Law, the Company shall afford to Parent and to Parent’s Representatives reasonable access during normal business hours (under the supervision of appropriate personnel and in a manner that does not unreasonably interfere with the normal operation of the business of the Company) during the Pre-Closing Period to its properties, books and records, Contracts and personnel, and, during such period, the Company shall furnish, as promptly as reasonably practicable, to Parent such information concerning its business, properties and personnel as Parent may reasonably request; provided that any such access shall be afforded and any such information shall be furnished at Parent’s expense. Notwithstanding the immediately preceding sentence, the Company shall not be required to afford access or furnish information to the extent (a) such information is subject to the terms of a confidentiality agreement with a third party entered into prior to the Agreement Date, (b) such information relates to the applicable portions of the minutes of the meetings of the Company Board (including any presentations or other materials prepared by or for the Company Board) where the Company Board discussed (or is information otherwise related to) (i) the Transactions or any similar transaction involving the sale of the Company, or a material portion of its assets, to, the license of a material portion of the Company’s assets to, or combination of the Company with, any other Person, (ii) any Company Takeover Proposal or (iii) any Intervening Event, or (c) the Company determines in good faith after consulting with counsel that affording such access or furnishing such information would jeopardize the attorney-client privilege of the Company, violate applicable Law or result in increased regulatory risk for the Company or the Transaction; provided that the Company will use its reasonable efforts to obtain any required consents for the disclosure of such information and take such other reasonable action (including entering into a joint defense agreement or similar arrangement to avoid loss of attorney-client privilege) with respect to such information as is necessary to permit disclosure to Parent without jeopardizing such attorney-client privilege, violating applicable Law or resulting in such regulatory risk, as applicable. All information exchanged pursuant to this Section 7.01 shall be subject to the confidentiality letter agreement dated March 21, 2024 between the Company and Parent, as amended (the “Confidentiality Agreement”).

In addition and without limiting the foregoing, the Company and the Company Board shall (A) take all action necessary to ensure that no restrictions on business combinations of any Takeover Law or similar statute or regulation is or becomes applicable to any Transaction or this Agreement and (B) if the restrictions on business combinations of any Takeover Law or similar statute or regulation becomes applicable to any Transaction or this Agreement, use its reasonable best efforts to take all action necessary to ensure that the Transactions may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such statute or regulation on the Transactions and this Agreement. Each of Parent and the Company shall take the actions set forth on Section 7.02(a) of the Company Disclosure Letter.

(b) Parent and the Company shall, or shall cause their ultimate parent entity as that term is defined in the HSR Act to, in consultation and cooperation with the other, file (i) with the FTC and DOJ the Notification and Report Form required under the HSR Act for the Offer, the Merger or any of the other Transactions as promptly as practicable (but in no event later than 10 Business Days after the Agreement Date) and (ii) all appropriate filings, notices, applications or similar documents required under any Foreign Antitrust Law applicable to the Transactions (as set forth in Section 7.02(b) of the Company Disclosure Letter) as promptly as practicable.

The parties hereto agree not to extend, directly or indirectly, any waiting period under the HSR Act or any Foreign Antitrust Law or enter into any agreement with a Governmental Entity to delay or not to consummate the Offer, the Merger or any of the other Transactions, except with the prior written consent of the other party. Without limiting the foregoing, each party hereto shall promptly provide to the other (or the other’s respective advisors) copies of all material correspondence between such party and any Governmental Entity relating to the Transactions. The parties hereto may, as they deem advisable and necessary, designate any competitively sensitive materials provided to the other under this Section 7.02 as “outside counsel only.” Such materials and the information contained therein shall be given only to outside counsel of the recipient and will not be disclosed by such outside counsel to employees, officers, or directors of the recipient without the advance written consent of the party providing such materials.

(c) In furtherance of the foregoing and subject to the terms and conditions set forth in this Agreement, Parent and Merger Sub agree to take promptly any and all steps necessary to avoid, eliminate or resolve each and every impediment and obtain all clearances, consents, approvals and waivers under the HSR Act or any Foreign Antitrust Law that may be required by any Governmental Entity, so as to enable the parties hereto to expeditiously close the Transactions (and in any event by or before the Outside Date). Parent and the Company acknowledge and agree that their obligation to use reasonable best efforts includes negotiating, committing to and effecting by consent decree, hold separate orders, or otherwise, the sale, divestiture, hold separate, license or other disposition of any assets, products, product lines, properties or services or businesses of the Company or any Company Subsidiary necessary to eliminate each and every impediment to close the transactions contemplated hereby prior to the Outside Date (such actions, the “Remedy Actions”); provided that, notwithstanding the foregoing or anything in this Agreement to the contrary, (i) neither Parent nor any of its Affiliates shall be required to proffer, offer, commit to, consent to or agree to or effect any Remedy Action with respect to (A) any assets, products, product lines, properties, services or businesses or portions thereof of Parent or any of its Subsidiaries (other than solely the Company and the Company Subsidiaries, subject to the following clause (B)) or (B) any assets, products, product lines, properties, services or businesses or portions thereof of the Company or any Company Subsidiary if, in the case of this clause (B), any such Remedy Action would, individually or in the aggregate, reasonably be expected to be material and adverse to the Company and the Company Subsidiaries, taken as a whole, and (ii) in no event shall Parent, the Company or their respective Subsidiaries be required to proffer, offer, commit to, consent to or agree to or effect any Remedy Action unless such Remedy Action is conditioned upon the consummation of the Merger Closing.

SECTION 7.03 Employee Matters.

(a) For a period of one year following the Effective Time (the “Continuation Period”), Parent shall, or shall cause the Surviving Corporation to, provide to each Company Employee (i) (x) a base salary (or wage rate) and (y) target cash incentive opportunity that, in each case, is no less favorable than those provided to such Company Employee by the Company or either Company Subsidiary, as applicable, as of immediately prior to the Effective Time (including, for the avoidance of doubt, continuation of the Company’s 2024 Annual Bonus Plan (as defined in the Company Disclosure Letter) and payments thereunder, calculated and timely paid in accordance with past practice) and (ii) employee benefits (excluding cash incentive opportunities, equity and equity based awards, and change in control

52

plans, programs and arrangements) that are substantially comparable in the aggregate to those provided to such Company Employee by the Company or either Company Subsidiary, as applicable, as of immediately prior to the Effective Time or, at Parent’s election if greater, the other compensation and employee benefits provided to similarly situated new hires of Parent or its Affiliates, it being understood that this Section 7.03(a) shall not require the continuation of any particular benefit plan or the provision of duplicate benefits. Notwithstanding the foregoing, during the Continuation Period, Parent shall, and shall cause the Surviving Corporation to, provide any Company Employee who experiences a termination of employment under the circumstances set forth in Section 7.03(a) of the Company Disclosure Letter with severance benefits no less favorable than those set forth in Section 7.03(a) of the Company Disclosure Letter, subject to the Company Employee’s execution of a general release of claims in favor of the Company, Parent and related Persons.

(b) Following the time at which the Company Employees no longer participate in a Company Benefit Plan following the Effective Time, the Company Employees shall be eligible to participate in a corresponding plan of Parent, the Surviving Corporation or their respective Affiliates (the “Surviving Corporation Plans”) to the same extent as other similarly-situated employees of Parent and its Affiliates. In addition, and without limiting the generality of the foregoing, following the Effective Time, each Company Employee shall be immediately eligible to participate, without any waiting time, in any Surviving Corporation Plans which replace coverage under a comparable Company Benefit Plan in which such Company Employee participated immediately prior to the Effective Time. This Section 7.03 shall not be interpreted to require Parent, the Surviving Corporation or their respective Affiliates to duplicate any benefits that are provided under a Company Benefit Plan or Company Benefit Agreement following the Effective Time or to provide any particular plan or type or level of benefits.

(c) Without limiting the generality of Section 7.03(a), from and after the Effective Time, Parent shall or shall cause the Surviving Corporation to assume, honor and continue the Company Benefit Plans and Company Benefit Agreements in accordance with their respective terms as in effect as of immediately prior to the Effective Time; provided that this Section 7.03(c) shall not limit the ability of Parent or the Surviving Corporation, as applicable, to amend, modify or terminate any such Company Benefit Plan or Company Benefit Agreement in accordance with its terms as in effect as of immediately prior to the Effective Time, and subject, in the case of a Company Benefit Agreement, to the consent of any affected Company Employee who is party to such a Company Benefit Agreement and without limitation of the provisions of Section 7.03(a). Parent acknowledges that, as of the Effective Time, a “change in control” (or “change of control” or similar defined term, as applicable) shall have occurred for purposes of each Company Benefit Plan and Company Benefit Agreement set forth in Section 7.03(c) of the Company Disclosure Letter in which such definition appears.

(d) With respect to Surviving Corporation Plans, including any “employee benefit plan,” as defined in Section 3(3) of ERISA (but not including any equity compensation plans), maintained by Parent or any of its subsidiaries, for purposes of determining eligibility to participate, level of benefits and vesting, each Company Employee’s service with the Company (as well as service with any predecessor employer of the Company, to the extent service with the predecessor employer is recognized by the Company) shall be treated as service with Parent or an applicable subsidiary; provided that the foregoing service recognition shall not apply to (i) the extent that it would result in duplication of benefits for the same period of services, (ii) any benefit plan that is a frozen plan or that provides benefits to a grandfathered employee population or (iii) determining years of service under any Parent program that provides for accelerated vesting of equity awards held by qualified retirement-eligible participants based on a formula that takes into account an employee’s age and service with Parent.

53

(e) With respect to any welfare plan maintained by Parent or any of its subsidiaries in which any Company Employee is eligible to participate after the Effective Time, Parent shall, and shall cause the Surviving Corporation to, use commercially reasonable efforts to (i) waive all limitations as to preexisting conditions and exclusions with respect to participation and coverage requirements applicable to such employees and their eligible dependents and beneficiaries, to the extent such limitations were waived, satisfied or did not apply to such employees or eligible dependents or beneficiaries under the corresponding welfare Company Benefit Plan in which such employees participated immediately prior to the Effective Time, (ii) provide Company Employees and their eligible dependents and beneficiaries with credit for any co-payments and deductibles paid prior to the Effective Time under any Company Benefit Plan in satisfying any analogous deductible or out-of-pocket maximum requirements for the year in which the Effective Time occurs and (iii) waive any waiting period or evidence of insurability requirement that would otherwise be applicable to a Company Employee and their eligible dependents on or after the Effective Time, in each case, to the extent such Company Employee or eligible dependent had satisfied any similar limitation or requirement under an analogous Company Benefit Plan prior to the Effective Time.

(f) With respect to any accrued but unused personal, sick or vacation time to which any Company Employee is entitled pursuant to the personal, sick or vacation policies applicable to such Company Employee immediately prior to the Effective Time, Parent shall, or shall cause the Surviving Corporation to, as applicable (and without duplication of benefits), recognize and allow such Company Employee to use such accrued personal, sick or vacation time in accordance with the practice and policies of Parent or the Surviving Corporation, as they may be amended from time to time.

(g) If requested by Parent no later than five (5) Business Days prior to the Merger Closing Date, the Company or the applicable Company Subsidiary shall adopt written resolutions to terminate the Company’s 401(k) plan effective as of the Business Day preceding the date on which the Offer Closing Time occurs. The Company shall provide Parent with an advance copy of such proposed resolutions and a reasonable opportunity to comment thereon prior to adoption or execution.

(h) The provisions of this Section 7.03 are solely for the benefit of the parties hereto, and no provision of this Section 7.03 shall (i) create any third-party beneficiary rights in any Company Employee or any other Person (including any beneficiary or dependent thereof) in respect of any benefits that may be provided, directly or indirectly, under any Company Benefit Plan or Company Benefit Agreement or any Surviving Corporation Plan or other employee program or any plan or arrangement of Parent or any of its subsidiaries, (ii) be construed to modify, amend or establish any benefit plan, program or arrangement or (iii) in any way affect the ability of the parties hereto or any other Person to modify, amend or terminate any of its benefit plans, programs or arrangements. Nothing in this Agreement shall confer upon any director, employee or service provider of the Company any right to continue in the employ or service of the Surviving Corporation, Parent or any subsidiary or Affiliate thereof, or shall interfere with or restrict in any way the rights of the Surviving Corporation, Parent or any subsidiary or Affiliate thereof to discharge or terminate the services of any director, employee or individual service provider of the Company at any time for any reason whatsoever, with or without cause.

SECTION 7.04 Indemnification.

(a) All rights to indemnification and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time (and rights to advancement of expenses) now existing in favor of any Person who is or prior to the Effective Time becomes, or has been at any time prior to the Agreement Date, a director or officer of the Company or its predecessors (each, an “Indemnified Party”) as provided in the Company Charter, the Company Bylaws or any indemnification agreement between such Indemnified Party and the Company that is in effect as of the Agreement Date and that has been made available to Parent (i) shall be assumed by the Surviving Corporation, without further action, at the Effective Time, (ii) shall survive the Merger, (iii) shall continue in full force and effect in accordance with their terms with respect to any claims against any such Indemnified Party arising out of such acts or omissions and (iv) for a period of six years following the Agreement Date, shall not be amended, repealed or otherwise modified in any manner that would adversely affect any right thereunder of any such Indemnified Party. Parent shall ensure that the Surviving Corporation complies with and honors the foregoing obligations.

(b) Without limiting Section 7.04(a) or any rights of any Indemnified Party pursuant to any indemnification agreement, from and after the Effective Time, in the event of any threatened or actual Proceeding, whether civil, criminal or administrative, based in whole or in part on, or arising in whole or in part out of, or pertaining to (i) the fact that an Indemnified Party is or was a director or officer of the Company, the Company Subsidiaries or any of their respective predecessors or (ii) this Agreement or any of the Transactions, whether in any case asserted or arising before or after the Effective Time, the Surviving Corporation shall indemnify and hold harmless, as and to the fullest extent permitted by applicable Law, each such Indemnified Party against any losses, claims, damages, liabilities, costs, expenses (including reasonable attorney’s fees and expenses in advance of the final disposition of any Proceeding to each Indemnified Party to the fullest extent permitted by applicable Law upon receipt of any undertaking required by applicable Law), judgments, fines and amounts paid in settlement of or in connection with any such threatened or actual Proceeding. The Surviving Corporation shall cooperate with an Indemnified Party in the defense of any matter for which such Indemnified Party could seek indemnification hereunder; provided that Parent and the Surviving Corporation shall be entitled to assume the defense and appoint lead counsel for such defense, except to the extent (i) otherwise provided in an indemnification agreement set forth in the Company Disclosure Letter, (ii) Parent and the Surviving Corporation shall have failed to employ counsel reasonably satisfactory to the Indemnified Party in a timely fashion or (iii) Parent shall have failed to diligently prosecute such matter on the Indemnified Party’s behalf. The Surviving Corporation shall not settle, compromise or consent to the entry of any judgment in any threatened or actual Proceeding for which indemnification could be sought by an Indemnified Party hereunder, unless such settlement, compromise or consent includes an unconditional release of such Indemnified Party from all liability arising out of such Proceeding or such Indemnified Party otherwise consents in advance in writing to such settlement, compromise or consent. The Surviving Corporation’s obligations under this Section 7.04(b) shall continue in full force and effect for the period beginning upon the Effective Time and ending six years from the Effective Time; provided that all rights to indemnification in respect of any Proceeding asserted or made within such period shall continue until the final disposition of such Proceeding. Parent shall cause the Surviving Corporation to perform its obligations under this Section 7.04(b).

(c) At or prior to the Effective Time, the Company may obtain and fully pay the premium for “tail” directors’ and officers’ liability insurance policies in respect of acts or omissions occurring at or prior to the Effective Time (including for acts or omissions occurring in connection with the approval of this Agreement and the consummation of the Transactions) for the period beginning upon the Effective Time and ending six years from the Effective Time, covering each Indemnified Party and containing terms (including with respect to coverage and amounts) and conditions (including with respect to deductibles and exclusions) that are in the aggregate, no less favorable to any Indemnified Party than those of the Company’s directors’ and officers’ liability insurance policies in effect on the Agreement Date (the “Existing D&O Policies”); provided that the maximum aggregate annual premium for such “tail” insurance policies shall not exceed 300% of the aggregate annual premium payable by the Company for coverage pursuant to its most recent renewal under the Existing D&O Policies (the “Maximum Amount”). If such “tail” insurance policies have been obtained by the Company, Parent shall cause such “tail” insurance policies to be maintained in full force and effect, for their full term, and cause all obligations thereunder to be honored by it and the Surviving Corporation. In the event the Company does not obtain such “tail” insurance policies, then, for the period beginning upon the Effective Time and ending six years from the Effective Time, Parent shall either purchase such “tail” insurance policies or Parent shall maintain in effect the Existing D&O Policies in respect of acts or omissions occurring at or prior to the Effective Time (including for acts or omissions occurring in connection with the approval of this Agreement and the consummation of the Transactions); provided that (i) neither Parent nor the Surviving Corporation shall be required to pay an aggregate annual premium for such insurance policies in excess of the Maximum Amount and (ii) if the annual premium of such insurance coverage exceeds such amount, Parent or the Surviving Corporation shall be obligated to obtain the maximum amount of coverage available for the Maximum Amount.

55

(d) In the event that (i) the Surviving Corporation or any of its successors or assigns (A) consolidates with or merges into any other Person and is not the continuing or surviving corporation or entity of such consolidation or merger or (B) transfers or conveys all or a substantial portion of its properties or other assets to any Person or (ii) Parent or any of its successors or assigns dissolves the Surviving Corporation, then, and in each such case, Parent shall cause proper provision to be made so that the applicable successors and assigns or transferees expressly assume the obligations set forth in this Section 7.04.

(e) From and after the Effective Time, the obligations of Parent and the Surviving Corporation under this Section 7.04 shall not be terminated or modified in such a manner as to adversely affect any Indemnified Party to whom this Section 7.04 applies without the consent of such affected Indemnified Party. The provisions of this Section 7.04 are, from and after the Effective Time, intended to be for the benefit of, and shall be enforceable by, each Indemnified Party, their heirs and their representatives, and are in addition to, and not in substitution for, any other rights to which each Indemnified Party is entitled, whether pursuant to Law, Contract or otherwise.

(f) Parent shall pay all reasonable and documented expenses, including reasonable attorneys’ fees, that may be incurred by any Indemnified Party in successfully enforcing the indemnity and other obligations provided in this Section 7.04.

SECTION 7.05 Fees and Expenses. Except as set forth in Section 7.01, Section 7.04, Section 7.07 and Section 9.03, all fees and expenses incurred in connection with this Agreement, the Offer, the Merger and the other Transactions shall be paid by the party incurring such fees or expenses, whether or not the Offer or the Merger is consummated.

Parent and Merger Sub, on the one hand, and the Company, on the other hand, shall consult with each other before issuing, and provide each other the opportunity to review and comment upon, any press release or other public statements with respect to the Offer, the Merger and the other Transactions, and shall not issue any such press release or make any such public statement prior to such consultation, except as may be required by applicable Law (including in connection with the making of any filings or notifications required under the HSR Act or any Foreign Antitrust Laws in connection with the transactions described in this Agreement or to respond to any requests for information or documents made by a Governmental Entity investigating the transactions described in this Agreement), court process or by obligations pursuant to any listing agreement with any national or foreign securities exchange, in which case, the party required to make such press release or public statement shall use its reasonable best efforts to allow the other party a reasonable opportunity to review and comment on such press release or statement in advance of its issuance; provided that the restrictions set forth in this Section 7.06 shall not apply (i) in the event of a dispute between the parties relating to this Agreement or the Transactions, or (ii) to any release, announcement or disclosure made or proposed to be made by the Company with respect to a Company Takeover Proposal, Superior Company Proposal, Intervening Event, Adverse Recommendation Change or Intervening Event Adverse Recommendation Change that does not violate Section 6.02. Notwithstanding the foregoing, to the extent a press release or public statement has been approved and made in compliance with this Section 7.06, no separate approval shall be required in respect of such content to the extent replicated in whole or in part in any subsequent press release or public statement. The parties hereto agree that the initial press release to be issued with respect to the Transactions shall be in the form heretofore agreed to by the parties hereto.

56

SECTION 7.07 Transfer Taxes. Except as provided in Section 2.01(e) and Section 3.09(b), all stock transfer, real estate transfer, documentary, stamp, recording and other similar Taxes (including interest, penalties and additions to any such Taxes) (“Transfer Taxes”) imposed with respect to the Transactions shall be paid by the Parent or the Surviving Corporation, and the Company shall cooperate with Merger Sub and Parent in preparing, executing and filing any Tax Returns with respect to such Transfer Taxes.

SECTION 7.08 Stockholder Litigation. During the Pre-Closing Period, the Company shall notify Parent promptly of the commencement or written threat of any Proceedings by or on behalf of one or more stockholders of the Company or any third party, against the Company and/or its directors relating to this Agreement or the Transactions of which it has received notice and shall keep Parent promptly and reasonably informed regarding any such Proceedings. During the Pre-Closing Period, the Company shall provide Parent an opportunity to review and to propose comments to all material filings or responses to be made by the Company in connection with any such Proceedings, and the Company shall give reasonable and good faith consideration to any comments proposed by Parent (in each case, unless the Company has made an Adverse Recommendation Change, in which case this sentence will continue to apply to the extent such Proceeding does not relate to such Adverse Recommendation Change). In no event shall the Company enter into, agree to or disclose any settlement with respect to such Proceedings without Parent’s consent, such consent not to be unreasonably withheld, delayed or conditioned. In the event of any conflict or overlap between the provisions of this Section 7.08 and Section 6.01 or Section 7.02, this Section 7.08 will control.

SECTION 7.09 Rule 14d-10 Matters. Prior to the scheduled expiration of the Offer, the Company (acting through the Company Board and the compensation committee of the Company Board) shall take such actions as are necessary to cause to be exempt under Rule 14d-10(d) promulgated under the Exchange Act any employment compensation, severance or other employee benefit arrangement that has been, or after the Agreement Date will be, entered into by the Company with current or future directors, officers or employees of the Company.

SECTION 7.10 Rule 16b-3 Matters. Prior to the Effective Time, the Company shall take all steps as may be required to cause any dispositions or cancellations or deemed dispositions or cancellations of Company equity securities (including derivative securities) in connection with this Agreement or the Transactions by each individual who is a director or officer of the Company subject to Section 16 of the Exchange Act to be exempt under Rule 16b-3 under the Exchange Act.

SECTION 7.11 Merger Sub and Surviving Corporation Compliance. Parent shall cause Merger Sub or the Surviving Corporation, as applicable, to comply with all of its respective obligations under this Agreement and Merger Sub shall not engage in any activities of any nature except as provided in or contemplated by this Agreement.

58

ARTICLE IX

TERMINATION, AMENDMENT AND WAIVER

SECTION 9.01 Termination. This Agreement may be terminated at any time prior to the Offer Closing Time, notwithstanding adoption of this Agreement by Parent as sole stockholder of Merger Sub:

(a) by mutual written consent of Parent, Merger Sub and the Company;

(b) by either Parent or the Company:

(i) if the Offer Closing Time shall not have occurred on or before 11:59 p.m., Eastern time, on the date which is one year from the Agreement Date (the “Outside Date”); provided that the right to terminate this Agreement pursuant to this Section 9.01(b)(i) shall not be available to any party hereto if the failure of the Offer Closing Time to occur on or before the Outside Date is primarily due to a material breach of this Agreement by such party; or

(ii) if any Legal Restraint permanently preventing or prohibiting the consummation of the Offer or the Merger shall be in effect and shall have become final and non-appealable; provided that the right to terminate this Agreement pursuant to this Section 9.01(b)(ii) shall not be available to any party hereto if such Legal Restraint is primarily due to such party’s failure to comply in all material respects with its obligations under Section 7.02 in respect of any such Legal Restraint;

(c) by Parent, if the Company breaches or fails to perform any of its representations, warranties, covenants or obligations contained in this Agreement, which breach or failure to perform individually or in the aggregate with all such other breaches or failures to perform (i) would result in the failure of any of the conditions set forth in clause (ii) or (iii) of Exhibit A and (ii) cannot be or has not been cured prior to the earlier of (x) 30 days after the giving of written notice to the Company of such breach or failure to perform and (y) the Outside Date; provided that Parent and Merger Sub are not then in material breach of this Agreement;

(d) by Parent if an Adverse Recommendation Change has occurred;

(e) by the Company, if (i) Merger Sub fails to commence the Offer in violation of Section 2.01 (other than due to a violation by the Company of its obligations under Section 2.02(b)), (ii) Merger Sub shall have terminated the Offer prior to its expiration date (as such expiration date may be extended in accordance with Section 2.01(a)), other than in accordance with this Agreement or (iii) all of the Offer Conditions have been satisfied or waived by Merger Sub as of immediately prior to the expiration of the Offer and the Offer Closing Time shall not have occurred within five Business Days following the expiration of the Offer;

(f) by the Company, if Parent or Merger Sub breaches or fails to perform any of its representations, warranties, covenants or obligations contained in this Agreement (without regard to any qualifications or exceptions contained therein as to materiality or Parent Material Adverse Effect), which breach or failure to perform (i) would, individually or in the aggregate, result in a Parent Material Adverse Effect and (ii) has not been cured prior to the earlier of (x) 30 days after the giving of written notice to Parent or Merger Sub of such breach or failure to perform and (y) the Outside Date; provided that the Company is not then in material breach of this Agreement; or

59

(g) by the Company, if (i) the Company Board authorizes the Company to enter into a definitive written agreement constituting a Superior Company Proposal, (ii) the Company Board has complied in all material respects with its obligations under Section 6.02(b) in respect of such Superior Company Proposal and (iii) the Company has paid, or simultaneously with the termination of this Agreement pays, the Company Termination Fee due under Section 9.03(a) that is payable if this Agreement is terminated pursuant to this Section 9.01(g).

The party hereto desiring to terminate this Agreement pursuant to this Section 9.01 (other than pursuant to Section 9.01(a)) shall give written notice of such termination to each other party hereto and specify the applicable provision or provisions hereof pursuant to which such termination is being effected.

SECTION 9.02 Effect of Termination. In the event of termination of this Agreement by either the Company or Parent as provided in Section 9.01, this Agreement shall forthwith become void and have no effect, without any liability or obligation on the part of Parent or Merger Sub, on the one hand, or the Company, on the other hand (except to the extent that such termination results from Fraud or the Willful Breach by a party hereto of any representation, warranty, covenant or obligation set forth in this Agreement, in which case such party may be liable to the other party hereto for damages which shall include, in the case of a breach by Parent or Merger Sub, liability to the Company for loss of economic benefits to the Company, including as a result of any foregone opportunities, or damages based on lost stockholder premium), the last sentence of Section 7.01, this Section 9.02, Section 9.03 and Article X, and any definitions contained in this Agreement and referred to but not contained in any such provisions, which provisions and definitions shall survive such termination. Without limiting the generality of the foregoing, Parent and Merger Sub acknowledge and agree that any failure of Parent or Merger Sub to satisfy its obligations to irrevocably accept for payment or pay for the shares of Company Common Stock following satisfaction of the Offer Conditions, and any failure of Parent to cause the Merger to be effective following the satisfaction of the conditions set forth in Article VIII, will be deemed to constitute a Willful Breach of a covenant of this Agreement.

SECTION 9.03 Termination Fees.

(a) The Company shall pay to Parent a fee of $173,000,000 (the “Company Termination Fee”) if:

(i) the Company terminates this Agreement pursuant to Section 9.01(g);

(ii) Parent terminates this Agreement pursuant to Section 9.01(d); or

(iii) (A) after the Agreement Date, a bona fide Company Takeover Proposal is proposed or announced or shall have become known to the Company Board and such Company Takeover Proposal is not withdrawn (x) in the case of this Agreement being subsequently terminated pursuant to Section 9.01(b)(i), prior to the date that is four Business Days prior to the final expiration date of the Offer or (y) in the case of this Agreement being subsequently terminated pursuant to Section 9.01(c), prior to the time of the breach giving rise to such termination, (B) this Agreement is terminated by (x) either Parent or the Company pursuant to Section 9.01(b)(i) (but in the case of a termination by the Company, only if at such time Parent would not be prohibited from terminating this Agreement pursuant to the proviso in Section 9.01(b)(i), and in the case of a termination by either Parent or the Company, only if at the time of any such termination, the Regulatory Condition and the Offer Condition set forth in clause (i) of Exhibit A shall have been satisfied but the Minimum Tender Condition shall not have been satisfied) or (y) Parent pursuant to Section 9.01(c) as a result of a breach by the Company of a covenant in this Agreement, and (C) within 12 months after such termination, the Company consummates any Company Takeover Proposal or the Company enters into a definitive acquisition agreement with respect to any Company Takeover Proposal that is subsequently consummated (whether such consummation occurs during or after such 12-month period).

60

For purposes of this Section 9.03(a), the term “Company Takeover Proposal” shall have the meaning set forth in the definition of Company Takeover Proposal contained in Section 1.01 except that (x) all references to 20% shall be deemed references to 50% and (y) clause (iii) of the definition thereof shall be omitted. Any fee due under this Section 9.03(a) shall be paid by wire transfer of same-day funds to an account designated by Parent, (1) in the case of clause (i), prior to or simultaneously with such termination of this Agreement, (2) in the case of clause (ii), within two Business Days after the date of such termination of this Agreement and (3) in the case of clause (iii), within two Business Days after the consummation of such a transaction. The parties hereto acknowledge and agree that in no event shall the Company be required to pay the Company Termination Fee on more than one occasion, whether or not the Company Termination Fee may be payable under more than one provision of this Agreement at the same or at different times and the occurrence of different events.

(b) Acceptance by Parent of the fee due under Section 9.03(a)(i) shall constitute acceptance by Parent of the validity of the termination of this Agreement under Section 9.01(g). In the event the Company Termination Fee described in this Section 9.03 is paid to Parent in accordance with Section 9.03(a), such Company Termination Fee shall be deemed to be liquidated damages for any and all losses or damages suffered or incurred by Parent or Merger Sub and constitute their sole and exclusive remedy of Parent and Merger Sub against the Company and its current, former or future stockholders and Representatives for any loss suffered as a result of the failure of the Transactions to be consummated, and none of the Company and its current, former or future stockholders or Representatives shall have any further liability or obligation relating to or arising out of this Agreement or the Transactions; provided that nothing contained in this Agreement shall relieve any party hereto from liability for Fraud or its Willful Breach of this Agreement. If the Company fails to pay in a timely manner the Company Termination Fee due pursuant to Section 9.03(a) and, in order to obtain such payment, Parent makes a claim that results in a judgment for the Company Termination Fee, the Company shall pay to Parent its reasonable costs and expenses (including reasonable attorneys’ fees and expenses) in connection with such suit, together with interest on the Company Termination Fee at the prime rate of Citibank, N.A. in effect from time to time from the date such payment was required to be made hereunder through the date such payment was actually received.

(c) Each of the parties hereto acknowledges that the agreements contained in this Section 9.03 are an integral part of the Transactions and that, without these agreements, the parties hereto would not enter into this Agreement.

SECTION 9.04 Amendment; Extension; Waiver.

(a) This Agreement may be amended by the parties hereto at any time prior to the Offer Closing Time. At any time prior to the Offer Closing Time, the parties hereto may (i) extend the time for the performance of any of the obligations or other acts of the other parties hereto, (ii) waive any inaccuracies in the representations and warranties contained in this Agreement or in any document delivered pursuant to this Agreement or (iii) waive compliance with any of the agreements or conditions contained in this Agreement (subject to Section 2.01). This Agreement may not be amended or supplemented after the Offer Closing Time.

(b) This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto. Any agreement on the part of a party hereto to any extension or waiver with respect to this Agreement shall be valid only if set forth in an instrument in writing signed on behalf of such party. The failure of any party hereto to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights.

61

SECTION 9.05 Procedure for Termination, Amendment, Extension or Waiver. A termination of this Agreement pursuant to Section 9.01 or an amendment of this Agreement or an extension or waiver with respect to this Agreement pursuant to Section 9.04 shall, in order to be effective, require, in the case of Parent, Merger Sub or the Company, action by its Board of Directors or the duly authorized designee of its Board of Directors. Termination of this Agreement pursuant to Section 9.01 shall not require the approval of the stockholders of the Company or Parent as sole stockholder of Merger Sub.

SECTION 10.03 Severability. If any term or other provision of this Agreement is determined by a court of competent jurisdiction to be invalid, illegal or incapable of being enforced by any rule or law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in an acceptable manner to the end that Transactions are fulfilled to the extent possible.

SECTION 10.04 Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties hereto and delivered to the other parties hereto. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or other electronic image scan transmission shall be effective as delivery of a manually executed counterpart of this Agreement.

SECTION 10.05 Entire Agreement; Third-Party Beneficiaries; No Other Representations or Warranties.

(a) This Agreement (including all Exhibits, Annexes and Schedules, including the Company Disclosure Letter, attached to this Agreement) and the Confidentiality Agreement (including all Exhibits, Annexes or Schedules thereto) (i) constitute the entire agreement, and supersede all prior agreements and understandings, both written and oral, among the parties hereto and their Affiliates, or any of them, with respect to the subject matter of this Agreement and the Confidentiality Agreement and (ii) except for Section 7.04, are not intended to confer upon any Person other than the parties hereto any rights or remedies. Notwithstanding clause (ii) of the immediately preceding sentence, (x) following the Effective Time the provisions of Article III shall be enforceable by holders of Certificates and holders of Book-Entry Shares solely to the extent necessary to receive the Merger Consideration to which such holders are entitled to thereunder, the provisions of Section 3.10 shall be enforceable by holders of awards under the Company Stock Plans and the provisions of Section 3.11 shall be enforceable by the holders of Company Warrants and (y) the Company shall have the right, on its own behalf and on behalf of the holders of Company Common Stock, the holders of awards under the Company Stock Plans and the holders of Company Warrants (each of which are third party beneficiaries of this Agreement to the extent required for this proviso to be enforceable), to pursue specific performance as set forth in Section 10.08 or, if specific performance is not sought or granted as a remedy, damages in accordance with this Agreement (which may include, among other things, the loss of economic benefits to the Company, including as a result of foregone opportunities, and may be based on the benefit of the bargain lost by such holders) in the event of a breach hereof by Parent or Merger Sub of this Agreement, it being agreed that in no event shall any such holder be entitled to enforce any of their rights, or any of Parent’s or Merger Sub’s obligations, under this Agreement in the event of any such breach, but rather the Company shall have, to the fullest extent permitted by Law, the sole and exclusive right to do so, as agent for such holders.

63

(b) Except for the representations and warranties contained in Article IV, each of Parent and Merger Sub acknowledges that neither the Company nor any Person on behalf of the Company makes, and neither Parent nor Merger Sub is relying on, any other express or implied representation or warranty with respect to the Company or with respect to any other information made available to Parent or Merger Sub in connection with the Transactions (including with respect to the accuracy or completeness thereof). In connection with the due diligence investigation of the Company by Parent and Merger Sub, Parent and Merger Sub have received and may continue to receive from the Company certain estimates, projections, forecasts and other forward-looking information, as well as certain business plans and cost-related plan information, regarding the Company’s business and operations. Parent and Merger Sub hereby acknowledge that there are uncertainties inherent in attempting to make such estimates, projections, forecasts and other forward-looking information, with which Parent and Merger Sub are familiar, that Parent and Merger Sub are making their own evaluation of the adequacy and accuracy of all estimates, projections, forecasts and other forward-looking information, as well as such business plans and cost-related plans, furnished to them (including the reasonableness of the assumptions underlying such estimates, projections, forecasts, forward-looking information, business plans or cost-related plans), and that neither Parent nor Merger Sub has relied upon the Company or its stockholders, directors, officers, employees, Affiliates, advisors, agents or other Representatives, or any other Person, with respect thereto. Accordingly, each of Parent and Merger Sub hereby acknowledge that neither the Company nor its stockholders, directors, officers, employees, Affiliates, advisors, agents or other Representatives, nor any other Person, has made or is making any representation or warranty or has or shall have any liability (whether pursuant to this Agreement, in tort or otherwise) with respect to such estimates, projections, forecasts, forward-looking information, business plans or cost-related plans (including the reasonableness of the assumptions underlying such estimates, projections, forecasts, forward-looking information, business plans or cost-related plans), except as expressly set forth in Article IV.

(c) Except for the representations and warranties contained in Article V, the Company acknowledges that none of Parent, Merger Sub and any other Person on behalf of Parent or Merger Sub makes, and the Company is not relying on, any other express or implied representation or warranty with respect to Parent or Merger Sub or with respect to any other information made available to the Company in connection with the Transactions (including with respect to the accuracy or completeness thereof).

SECTION 10.06 Governing Law. 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.

SECTION 10.07 Assignment. Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned, in whole or in part, by operation of law or otherwise by any of the parties hereto without the prior written consent of the other parties hereto, and any purported assignment in violation of this provision shall be void; provided that Merger Sub may assign, in its sole discretion, any of or all its rights, interests and obligations under this Agreement to Parent or to any direct or indirect wholly owned subsidiary of Parent, but no such assignment shall relieve Merger Sub of any of its obligations under this Agreement; provided, further, that any such assignment shall not take place after the commencement of the Offer and shall not otherwise materially impede or delay the consummation of the Transactions or otherwise materially impede the rights of the stockholders of the Company under this Agreement. Any purported assignment without such consent shall be void. Subject to the preceding sentences, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the parties hereto and their respective successors and assigns.

SECTION 10.08 Specific Enforcement; Jurisdiction.

(a) The parties hereto acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with its specific terms or were otherwise breached, and that monetary damages, even if available, would not be an adequate remedy therefor. It is accordingly agreed that the parties hereto shall be entitled to an injunction or injunctions, or any other appropriate form of equitable relief, to prevent breaches of this Agreement and to enforce specifically the performance of the terms and provisions of this Agreement in any court referred to in Section 10.08(b), without proof of damages or otherwise (and each party hereto hereby waives any requirement for the securing or posting of any bond in connection with such remedy), this being in addition to any other remedy to which they are entitled at law or in equity. The right to specific enforcement shall include the right of the Company to cause Parent and Merger Sub to cause the Offer, the Merger and the other Transactions to be consummated on the terms and subject to the conditions set forth in this Agreement. The parties hereto further agree not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to Law or inequitable for any reason, nor to assert that a remedy of monetary damages would provide an adequate remedy. Each of the parties hereto acknowledges and agrees that the right of specific enforcement is an integral part of the Transactions and without such right, none of the parties hereto would have entered into this Agreement. If, prior to the Outside Date, any party hereto brings any Proceeding, in each case, in accordance with Section 10.08(b), to enforce specifically the performance of the terms and provisions hereof by any other party hereto, the Outside Date shall automatically be extended by (i) the amount of time during which such Proceeding is pending, plus 20 Business Days or (ii) such other time period established by the court presiding over such Proceeding, as the case may be.

(b) Each of the parties hereto hereby irrevocably submits to the exclusive jurisdiction of the courts of the State of Delaware and to the jurisdiction of the United States District Court for the State of Delaware, for the purpose of any Proceeding arising out of or relating to this Agreement or the actions of Parent, Merger Sub or the Company in the negotiation, administration, performance and enforcement thereof, and each of the parties hereto hereby irrevocably agrees that all claims with respect to such Proceeding may be heard and determined exclusively in the Delaware Court of Chancery or, solely if the Delaware Court of Chancery does not have subject matter jurisdiction thereof, any other court of the State of Delaware or any federal court sitting in the State of Delaware. Each of the parties hereto (i) consents to submit itself to the personal jurisdiction of the Delaware Court of Chancery, any other court of the State of Delaware and any federal court sitting in the State of Delaware in the event any Proceeding arises out of this Agreement, the Offer, the Merger or any of the other Transactions, (ii) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court, (iii) irrevocably consents to the service of process in any Proceeding arising out of or relating to this Agreement, the Offer, the Merger or any of the other Transactions, on behalf of itself or its property, by U.S. registered mail to such party’s respective address set forth in Section 10.02 (provided that nothing in this Section 10.08(b) shall affect the right of any party hereto to serve legal process in any other manner permitted by Law) and (iv) agrees that it will not bring any Proceeding relating to this Agreement, the Offer, the Merger or any of the other Transactions in any court other than the Delaware Court of Chancery (or, solely if the Delaware Court of Chancery shall be unavailable, any other court of the State of Delaware or any federal court sitting in the State of Delaware). The parties hereto agree that a final trial court judgment in any such Proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law; provided that nothing in the foregoing shall restrict any party’s rights to seek any post-judgment relief regarding, or any appeal from, such final trial court judgment.

SECTION 10.09 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY PROCEEDING ARISING OUT OF THIS AGREEMENT, THE OFFER, THE MERGER OR ANY OF THE OTHER TRANSACTIONS. EACH PARTY HERETO

65

(A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH PARTY WOULD NOT, IN THE EVENT OF ANY PROCEEDING, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVER AND CERTIFICATIONS IN THIS SECTION 10.09.

SECTION 10.10 Remedies. Except as otherwise provided in this Agreement, the rights and remedies provided in this Agreement shall be cumulative and not exclusive of any rights or remedies provided by applicable Law, and the exercise by a party hereto of any one remedy will not preclude the exercise of any other remedy.

SECTION 10.11 Cooperation. The parties hereto agree to provide reasonable cooperation with each other and to execute and deliver such further documents, certificates, agreements and instruments and to take such actions as may be reasonably requested by the other parties hereto to evidence or effect the Transactions and to carry out the intent and purposes of this Agreement.

Notwithstanding any other term of the Offer or the Agreement, Merger Sub shall not be required to, and Parent shall not be required to cause Merger Sub to, accept for payment or, subject to any applicable rules and regulations of the SEC, including Rule 14e-1(c) under the Exchange Act (relating to Merger Sub’s obligation to pay for or return tendered shares of Company Common Stock promptly after the termination or withdrawal of the Offer), pay for any shares of Company Common Stock tendered pursuant to the Offer (and not theretofore accepted for payment or paid for) unless (a) there shall have been validly tendered in the Offer (and not properly withdrawn) prior to the expiration of the Offer that number of shares of Company Common Stock (excluding shares tendered pursuant to guaranteed delivery procedures that have not yet been “received” by the “depository,” as such terms are defined by Section 251(h) of the DGCL) that, when added to the shares of Company Common Stock then owned by Parent, Merger Sub or any subsidiary of Parent, would represent at least a majority of the Company Common Stock outstanding as of immediately following the consummation of the Offer, including, for the avoidance of doubt, the Company Common Stock issued upon the automatic exercise of any then-outstanding Other Company Warrants upon the Offer Closing Time (such condition in this clause (a), the “Minimum Tender Condition”) and (b) the waiting period under the HSR Act applicable to the purchase of shares of Company Common Stock pursuant to the Offer and the consummation of the Merger shall have either expired or been terminated, and the waiting periods, approvals, clearances and consents listed in Section 7.02(b) of the Company Disclosure Letter shall have terminated, expired or been obtained, as applicable (such condition in this clause (b), the “Regulatory Condition”).

Furthermore, notwithstanding any other term of the Offer or this Agreement, Merger Sub shall not be required to, and Parent shall not be required to cause Merger Sub to, accept for payment or, subject as aforesaid, to pay for any shares of Company Common Stock not theretofore accepted for payment or paid for if, at the then-scheduled expiration of the Offer, any of the following conditions exists:

(i) there shall be any Legal Restraint in effect preventing or prohibiting the consummation of the Offer or the Merger (in each case, whether temporary, preliminary or permanent in nature);

(ii) (A) any representation or warranty of the Company set forth in Article IV (other than those set forth in Sections 4.01 (Organization, Standing and Power) (but only with respect to the first and second sentences thereof), 4.02(a), (c) and (d) (Capital Structure), 4.04 (Authority; Execution and Delivery; Enforceability), 4.08(a) (Absence of Certain Changes or Events), 4.21 (Brokers and Other Advisors), 4.23 (Opinion of Financial Advisors) and 4.24 (No Vote Required)) shall not be true and correct at and as of the Agreement Date and at and as of such time, except to the extent such representation or warranty expressly relates to a specified date (in which case on and as of such specified date), other than for such failures to be true and correct that have not had or would not reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect (for purposes of determining the satisfaction of this condition, without regard to any qualifications or exceptions contained therein as to “materiality” or “Company Material Adverse Effect”), (B) any representation or warranty of the Company set forth in Sections 4.01 (Organization, Standing and Power) (but only with respect to the first and second sentences thereof), 4.04 (Authority; Execution and Delivery; Enforceability), 4.21 (Brokers and other Advisors), 4.23 (Opinion of Financial Advisors) and 4.24 (No Vote Required) shall not be true and correct in all material respects at and as of the Agreement Date and at and as of such time, except to the extent such representation or warranty expressly relates to a specified date (in which case on and as of such specified date), (C) any representation or warranty of the Company set forth in Section 4.02(a), (c) and (d) (Capital Structure) shall not be true and correct other than in de minimis respects at and as of the Agreement Date and at and as of such time, except to the extent such representation or warranty expressly relates to a specified date (in which case on and as of such specified date) and (D) any representation or warranty of the Company set forth in Section 4.08(a) (Absence of Certain Changes or Events) shall not be true and correct in all respects as of such time;

(iii) the Company shall have failed to perform in all material respects the obligations to be performed by it as of such time under this Agreement;

(iv) since the Agreement Date, there shall have occurred any change, event, condition, development, circumstance, state of facts, effect or occurrence which, individually or in the aggregate, has had, or would reasonably be expected to have, a Company Material Adverse Effect and such Company Material Adverse Effect is continuing as of immediately prior to the Effective Time;

(v) Parent shall have failed to receive from the Company a certificate, dated as of the date on which the Offer expires and signed by an executive officer of the Company, certifying to the effect that the Offer Conditions set forth in clauses (ii), (iii) and (iv) have been satisfied as of immediately prior to the expiration of the Offer; or

(vi) this Agreement shall have been validly terminated in accordance with its terms (the “Termination Condition”).

The foregoing conditions shall be in addition to, and not a limitation of, the rights of Parent and Merger Sub to extend, terminate or modify the Offer in accordance with the terms and conditions of this Agreement.

The foregoing conditions are for the sole benefit of Parent and Merger Sub and, subject to the terms and conditions of this Agreement and the applicable rules and regulations of the SEC, may be waived by Parent and Merger Sub in whole or in part at any time and from time to time in their sole discretion (other than the Minimum Tender Condition and the Termination Condition, which may not be waived by Parent or Merger Sub). The failure by Parent, Merger Sub or any other Affiliate of Parent at any time to exercise any of the foregoing rights shall not be deemed a waiver of any such right, the waiver of any such right with respect to particular facts and circumstances shall not be deemed a waiver with respect to any other facts and circumstances and each such right shall be deemed an ongoing right that may be asserted at any time and from time to time.
