The Buyer Entities expressly reserve the right to waive, in their sole discretion, in whole or in part, any Offer Condition or modify the terms of the Offer in any manner not inconsistent with this Agreement, except that the Minimum Tender Condition shall not be waived, and, without the prior written consent of the Company, the Buyer Entities shall not, (i) reduce the number of shares of the Company Common Stock subject to the Offer, (ii) reduce the Offer Price, (iii) waive, amend or modify the Termination Condition, (iv) add to the Offer Conditions or impose any other conditions on the Offer or amend, modify or supplement any Offer Condition in any manner adverse to the holders of the Company Common Stock, (v) except as otherwise provided in this Section 2.01, terminate, or extend or otherwise amend or modify the expiration date of, the Offer, (vi) change the form or terms of consideration payable in the Offer, (vii) otherwise amend, modify or supplement any of the terms of the Offer in any manner adverse to the holders of the Company Common Stock or (viii) provide any “subsequent offering period” in accordance with Rule 14d-11 of the Exchange Act.

On the terms and subject only to the conditions of the Offer and this Agreement, the Buyer Entities shall irrevocably accept for payment, and pay for, all shares of the Company Common Stock validly tendered and not properly withdrawn pursuant to the Offer that Merger Sub becomes obligated to purchase pursuant to the Offer as promptly as practicable after the expiration of the Offer and, in any event, no more than three (3) Business Days after the expiration of the Offer. The time at which Merger Sub first irrevocably accepts for purchase the shares of the Company Common Stock tendered in the Offer is referred to as the “Offer Closing Time.” The Offer may not be terminated or withdrawn prior to its expiration date (as such expiration date may be extended and re-extended in accordance with this Section 2.01(a)), unless this Agreement is validly terminated in accordance with Section 9.01. If this Agreement is validly terminated in accordance with Section 9.01, Merger Sub shall promptly and irrevocably terminate the Offer and return, and shall cause any depository acting on behalf of Merger Sub to return, all tendered shares of the Company Common Stock to the registered holders thereof. Nothing contained in this Section 2.01(a) shall affect any termination rights set forth in Section 9.01.

(b) Schedule TO; Offer Documents. As promptly as reasonably practicable on the date of commencement of the Offer, the Buyer Entities shall (i) file with the SEC a Tender Offer Statement on Schedule TO with respect to the Offer, which shall include an offer to purchase and a related letter of transmittal and summary advertisement containing the terms set forth in this Agreement and Exhibit A (such Schedule TO, as amended from time to time, and the documents included therein pursuant to which the Offer will be made, together with any supplements or amendments thereto, the “Offer Documents”) and (ii) disseminate the Offer Documents to the holders of the Company Common Stock as and to the extent required by applicable Law.

(c) Confirmation of Closing Net Cash.

(i) If, between the Agreement Date and the Offer Closing Time, the outstanding shares of the 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 Offer Price shall be appropriately adjusted and such adjustment to the Offer Price shall provide to the holders of shares of Company Common Stock the same economic effect as contemplated by this Agreement prior to such action.

(ii) Except as otherwise contemplated in this Section 2.01(c), on the tenth (10th) Business Day before the scheduled expiration of the Offer (including as extended pursuant to Section 2.01(a)), the Company shall deliver to Parent a schedule (the “Closing Cash Schedule”) setting forth, in reasonable detail, the Company’s good faith, estimated calculation of Closing Net Cash (the “Closing Cash Calculation”) as of the close of business on the date of the Offer Closing Time (the “Cash Determination Time”) based on such scheduled expiration of the Offer. The Company shall make available to Parent, as reasonably requested by Parent, the work papers and back-up materials used or any other relevant information useful in preparing the Closing Cash Schedule, including close-out memos or other forms of written affirmation from vendors that either no more money is due or an amount of money is due that is reflected on the Closing Cash Schedule. If reasonably requested by Parent, reasonable access to the Company’s accountants and counsel at reasonable times and upon reasonable notice will be provided by the Company in order to permit Parent to review the Closing Cash Calculation. The Closing Cash Calculations shall include the Company’s determination, as of the Cash Determination Time, of the Cash Amount and each component thereof.

18

(iii) Parent shall have the right to dispute any part of the Closing Cash Calculation by delivering a written notice (for which email will suffice) (a “Dispute Notice”) to that effect to the Company on or prior to 11:59 p.m., Eastern Time, on the fifth (5th) Business Day following Parent’s receipt of the Closing Cash Schedule (the “Response Time”), which Dispute Notice shall identify in reasonable detail the nature and amounts of any proposed revisions to the proposed Closing Cash Calculation and shall be accompanied by a reasonably detailed explanation for the basis for such revisions.

(iv) If, on or prior to the Response Time, Parent notifies the Company in writing that it has no objections to the Closing Cash Calculation or if Parent fails to deliver a Dispute Notice as provided in Section 2.01(c)(iii) prior to the Response Time, then the Closing Cash Calculation as set forth in the Closing Cash Schedule shall be deemed to have been finally determined for purposes of this Agreement and shall represent the Closing Net Cash at the Cash Determination Time for purposes of this Agreement.

(v) If Parent delivers a Dispute Notice on or prior to the Response Time, then Representatives of the Company and Parent shall promptly (and in no event later than one (1) Business Day thereafter) meet and attempt in good faith to resolve the disputed item(s) and negotiate an agreed-upon determination of the Closing Net Cash, which agreed upon Closing Net Cash amount shall be deemed to have been finally determined for purposes of this Agreement and shall represent the Closing Net Cash at the Cash Determination Time for purposes of this Agreement.

(vi) If Representatives of the Company and Parent are unable to negotiate an agreed-upon determination of Closing Net Cash as of the Cash Determination Time pursuant to Section 2.01(c)(v) within three (3) Business Days after delivery of the Dispute Notice (or such other period as the Company and Parent may mutually agree upon), then any remaining disagreements as to the calculation of Closing Net Cash shall be referred to for resolution to KPMG, or, if such accounting firm is unable to serve, the Company and Parent shall, within two (2) Business Days, appoint by mutual agreement the office of an impartial nationally or regionally recognized firm of independent certified public accountants other than the Company’s accountants or Parent’s accountants (the “Accounting Firm”). The Company and Parent shall promptly deliver to the Accounting Firm the work papers and back-up materials used in preparing the Closing Cash Schedule and the Dispute Notice, and the Company and Parent shall use commercially reasonable efforts to cause the Accounting Firm to make its determination within three (3) Business Days of accepting its selection. The Company and Parent shall be afforded the opportunity to present to the Accounting Firm any materials related to the unresolved disputes and to discuss the issues with the Accounting Firm; provided that no such presentation or discussion shall occur without the presence of a Representative of each of the Company and Parent. The determination of the Accounting Firm shall be limited to the disagreements submitted to the Accounting Firm. The determination of the amount of Closing Net Cash made by the Accounting Firm shall be made in writing delivered to each of the Company and Parent, shall be final and binding on the Company and Parent and shall (absent manifest error) be deemed to have been finally determined for purposes of this Agreement and to represent the Closing Net Cash at the Cash Determination Time

19

for purposes of this Agreement. The Buyer Entities shall extend the expiration date of the Offer until the resolution of the matters described in this Section 2.01(c)(vi); provided, that the Buyer Entities shall not, and shall not be required to, extend the Offer beyond the Outside Date. The fees and expenses of the Accounting Firm shall be allocated between the Company and Parent in the same proportion that the disputed amount of the Closing Net Cash that was unsuccessfully disputed by such party (as finally determined by the Accounting Firm) bears to the total disputed amount of the Closing Net Cash amount and the Company’s portion of such fees and expenses shall be included in the calculation of Transaction Expenses. If this Section 2.01(c)(vi) applies as to the determination of the Closing Net Cash at the Cash Determination Time with respect to a scheduled expiration of the Offer, upon resolution of the matter in accordance with this Section 2.01(c)(vi), the parties shall not be required to determine Closing Net Cash again (solely with respect to such applicable scheduled expiration of the Offer) even though such applicable expiration of the Offer may occur later.

As of the Effective Time, all such shares of the Company Common Stock shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of any such shares of the Company Common Stock shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration in accordance with this Section 3.08(c). For the avoidance of doubt, at the Effective Time, any repurchase rights of the Company or other similar restrictions on shares of Company Common Stock shall lapse in full and will be of no further force or effect, and all shares of Company Common Stock shall be fully vested as of the Effective Time.

(d) Appraisal Rights. Notwithstanding anything in this Agreement to the contrary, shares (“Appraisal Shares”) of the Company Common Stock that are outstanding immediately prior to the Effective Time and that are held by any Person who is entitled to demand and properly demands appraisal of such Appraisal Shares pursuant to, and who complies in all respects with, Section 262 of the DGCL (“Section 262”) shall not be converted into the Merger Consideration as provided in Section 3.08(c), but instead, at the Effective Time, the Appraisal

23

Shares shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of any such Appraisal Shares shall cease to have any rights with respect thereto, except the right to receive payment of the fair value of such Appraisal Shares in accordance with Section 262; provided that if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal under Section 262 with respect to such Appraisal Shares or a court of competent jurisdiction shall determine that such holder is not entitled to the relief provided by Section 262, then the right of such holder to receive the fair value of such holder’s Appraisal Shares shall cease and such Appraisal Shares shall be deemed to have been converted as of the Effective Time into, and to have become exchangeable solely for, the right to receive the Merger Consideration as provided in Section 3.08(c). The Company shall give prompt written notice to Parent of any demands received by the Company for appraisal of any shares of the Company Common Stock, and Parent shall have the right to participate in, and direct all negotiations and Proceedings with respect to such demands. The Company shall not, without the prior written consent of Parent, make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing. 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. Not less than three (3) Business Days before the Merger Closing Date, 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 Cash Amount pursuant to Section 3.08(c). At or promptly after the Effective Time (and in any event, within two (2) Business Days of the Merger Closing Date), Parent shall deposit with the Paying Agent, for the benefit of holders of shares of the Company Common Stock, cash in U.S. dollars sufficient to pay the Cash Amount at the Effective Time pursuant to Section 3.08(c) (such cash being hereinafter referred to as the “Payment Fund”).

(b) Payment Procedure. As promptly as reasonably practicable (but in no event later than two (2) 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 the Company Common Stock (the “Certificates”) that were converted into the right to receive the Merger Consideration pursuant to Section 3.08(c) (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 into which the shares of the Company Common Stock theretofore represented by such Certificate shall have been converted pursuant to Section 3.08(c), and the Certificate so surrendered shall forthwith be canceled. In the event of a transfer of ownership of the 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

24

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, stamp, registration or other similar Taxes required by reason of the payment to a Person other than the registered holder of such Certificate or establish to the good faith satisfaction of Parent that any such Tax has been paid or is not applicable. 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 Merger Consideration (without interest) into which the shares of the Company Common Stock theretofore represented by such Certificate have been converted pursuant to Section 3.08(c). 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 the Merger Consideration into which such Book-Entry Shares shall have been converted pursuant to Section 3.08(c), 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 five (5) Business Days after the Effective Time to each such holder of record as of the Effective Time), an amount of U.S. dollars equal to the aggregate Cash Amount (without interest) to which such holder is entitled hereunder, and such Book-Entry Shares shall forthwith be canceled. Payment of the Cash Amount 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 the 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 the 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 the Company Common Stock shall be deemed to have been paid in full satisfaction of all rights pertaining to such shares of the 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 the 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.

(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 the Company Common Stock formerly represented by such lost, stolen or destroyed Certificate, the applicable Merger Consideration to be paid in respect of such shares.

25

(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 twelve (12)-month anniversary of the Merger Closing Date shall be delivered to the Company or its designated Affiliate, upon demand, and any former holder of the Company Common Stock entitled to payment of the Cash Amount who has not theretofore complied with this Article III shall thereafter look only to the Company or any successor-in-interest of the Company for payment of its claim for the Cash Amount (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 the 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 ▇▇▇▇▇▇. 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 Company Stockholders entitled to payment of the Cash Amount to receive the Cash Amount. 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 Cash Amount 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. Notwithstanding anything to the contrary, each of the Company, the Surviving Corporation, Parent and the Paying Agent shall be entitled to deduct and withhold from the amounts otherwise payable 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 Law. Amounts so deducted or withheld shall be treated for all purposes of this Agreement as having been paid to the Person in respect of whom such deduction or withholding was made. Provided IRS Forms W-9 or W-8 have been provided, Parent shall (i) use commercially reasonable efforts to provide advance notice of any such deduction or withholding (other than with respect to amounts paid as compensation) and (ii) cooperate with the Company and any holders of Company Common Stock or Company Equity Awards to obtain any affidavits, certificates and other documents as may reasonably be expected to afford to the Company and such holders reduction of or relief from any such deduction or withholding.

26

SECTION 3.10 Equity Awards.

(a) As of immediately prior to the Offer Closing Time, each Company Option that is then outstanding but not then vested or exercisable shall become immediately vested and exercisable in full.

(i) At the Effective Time, each In-the-Money Option that is then outstanding shall be canceled and the holder thereof shall be entitled to receive (A) an amount in cash without interest, equal to the product obtained by multiplying (x) the excess of the Cash Amount over the exercise price per share of the Company Common Stock underlying such Company Option at the Effective Time by (y) the number of shares of the Company Common Stock underlying such Company Option (such amount, the “Company Option Cash Consideration”) and (B) one CVR for each share of the Company Common Stock underlying such Company Option at the Effective Time. Parent shall cause the Surviving Corporation to pay the Company Option Cash Consideration at or reasonably promptly after the Effective Time (but in no event later than five (5) Business Days after the Effective Time).

(ii) At the Effective Time, each Out-of-the-Money Option that is then outstanding shall be automatically cancelled for no consideration and the holder thereof shall have no further rights with respect thereto.

(b) As of immediately prior to the Offer Closing Time, each Company Restricted Stock Unit Award that is then outstanding but not then vested shall become immediately vested in full. At the Effective Time, each Company Restricted Stock Unit Award that is then outstanding shall be canceled and the holder thereof shall be entitled to receive (i) an amount in cash without interest, equal to the product obtained by multiplying (x) the Cash Amount by (y) the number of shares of the Company Common Stock underlying such Company Restricted Stock Unit Award at the Effective Time (such amount, the “Restricted Stock Unit Cash Consideration”) and (ii) one CVR for each share of the Company Common Stock underlying such Company Restricted Stock Unit Award at the Effective Time. Parent shall cause the Surviving Corporation to pay the Restricted Stock Unit Cash Consideration at or reasonably promptly after the Effective Time (but in no event later than five (5) Business Days after the Effective Time).

(c) Prior to the Effective Time, the Company shall take all reasonable actions required to (A) terminate the Company ESPP, as of immediately prior to the Merger Closing Date and (B) provide that no new offering period shall commence after the date of this Agreement.

(d) Prior to the Effective Time, the Company Board (or, if appropriate, any committee thereof administering any Company Stock Plan) 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 Equity Awards 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; provided, that the Company ESPP shall terminate in accordance with Section 3.10(c) hereof.

27

SECTION 3.11 Contingent Value Right. At or prior to the Offer Closing Time, Parent will authorize and duly adopt, execute and deliver, and will ensure that a duly qualified rights agent with respect to the CVRs mutually agreeable to Parent and the Company (a “Rights Agent”) executes and delivers, a contingent value rights agreement in substantially the form attached as Exhibit C (the “CVR Agreement”), subject to any reasonable revisions to the CVR Agreement that are requested by such Rights Agent or the Representative thereunder (provided that such revisions are not, individually or in the aggregate, materially detrimental to any holder of CVRs). Parent and the Company shall cooperate, including by making changes to the form of CVR Agreement, as necessary to ensure that the CVRs are not subject to registration under the Securities Act, the Exchange Act or any applicable state securities or “blue sky” Laws.

The certifications and statements required by (i) Rule 13a-14 under the Exchange Act and (ii) 18 U.S.C. §1350 (Section 906 of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act) relating to the Company SEC Documents (collectively, the “Company Certifications”) are accurate and complete and comply as to form and content with all applicable Laws.

(g) The Company has established and maintains a system of internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-l5(f) of the Exchange Act) that is sufficient to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP, including policies and procedures sufficient to provide reasonable assurance that the Company maintains records that in reasonable detail accurately and fairly reflect the Company’s transactions and dispositions of assets. The Company has disclosed to the Company’s auditors and the Audit Committee of the Company Board (and made available to the Company a summary of the significant aspects of such disclosure) (A) all significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting that are reasonably likely to adversely affect the Company’s ability to record, process, summarize and report financial information and (B) any fraud, whether or not material, that involves management or other employees who have a significant role in the Company or its Subsidiaries’ internal control over financial reporting.

39

notice or lapse of time would reasonably be expected to allow, revocation, termination or material impairment of the rights of the holder of any Company Permits, where such revocation, termination, or impairment would reasonably be expected to have a Company Material Adverse Effect.

Parts 50, 54, 56, 58 and 312, and any other applicable regulations governing the conduct of such pre-clinical studies or clinical trials. Neither the Company nor any of its Subsidiaries has received any written notices, correspondence, or other written communications from any the FDA or any comparable Governmental Entity or institutional review board of any action to place a clinical hold order on, or otherwise terminate, materially delay, or suspend any clinical studies currently being conducted by or on behalf of, or sponsored by, the Company or any of its Subsidiaries with respect to the Company Product Candidates, other than ordinary course communications regarding the design and implementation of such clinical trials, and to the knowledge of the Company, there are no reasonable grounds for the same.

The Company shall, and shall cause its directors and officers to, and shall use its reasonable best efforts to 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 (other than Parent, Merger Sub or any designees or Representatives of Parent or Merger Sub) within the last six

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 material breach of this Section 6.02(a), in the event that the Company Board determines, in good faith, after consultation with outside counsel and an independent financial advisor, that such Company Takeover Proposal constitutes or could 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 (in any event within one (1) Business Day) 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 reasonably be likely to 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 publicly 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) publicly adopt, endorse, approve or recommend, or propose publicly to adopt, endorse, approve or recommend, any Company Takeover Proposal, (C) if any Company Takeover Proposal is structured as a tender offer or exchange offer (other than by Parent or an Affiliate of Parent), fail to recommend, within five (5) business days (as defined in Rule 14d-1(f) promulgated under the Exchange Act) after such commencement, against acceptance by the Company Stockholders of such tender offer or exchange offer or (D) fail to include the Company Board Recommendation in the Schedule 14D-9 when disseminated to the Company Stockholders (any action described in this clause (i) being referred to in this Agreement as an “Adverse Recommendation Change”) or (ii) enter into any letter of intent, memorandum of understanding, acquisition agreement, merger 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.

(c) Notwithstanding anything to contrary in the foregoing or any other provision of this Agreement, the Company Board may, in response to a Company Takeover Proposal that did not result from a material breach of this Section 6.02 effect an Adverse Recommendation Change if (1) the Company Board determines in good faith, after consultation with outside counsel, such Company Takeover Proposal constitutes a Superior Company Proposal,

56

(2) the Company Board shall have given Parent at least four (4) 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, subject to any restrictions pursuant to any confidentiality agreement in effect, 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), (3) the Company shall have negotiated, and shall have used its reasonable best efforts to cause 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 response to such Company Takeover Proposal, (4) 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 would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law. In the event of any material change to any of the financial terms (including the form and amount of consideration) of such Company Takeover Proposal, the Company shall deliver to Parent an additional Company Notice consistent with that described in clause (2) of this proviso and a renewed notice period under clause (2) of this proviso shall commence (except that the four (4)-Business Day notice period referred to in clause (2) of this proviso shall instead be equal to two (2) Business Days) during which time the Company shall be required to comply with the requirements of this Section 6.02(c) anew with respect to such additional Company Notice, including clauses (1) through (4) of this proviso.

(d) Notwithstanding anything to contrary in the foregoing or any other provision of this Agreement, the Company Board may, in response to an Intervening Event, effect an Adverse Recommendation Change if (1) the Company Board determines in good faith, after consultation with outside counsel, that the failure to make an Adverse Recommendation Change in response to such Intervening Event would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law, (2) the Company Board shall have given Parent at least four (4) Business Days’ prior written notice through a Company Notice of its intention to take such action and a description of the reasons for taking such action (which shall include a reasonably detailed description of the underlying facts giving rise to such action), (3) the Company shall have negotiated, and shall have used its reasonable best efforts to cause 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 response to such Intervening Event, (4) 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 in response to such Intervening Event would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law. In the event of any material change in any event, occurrence or facts relating to such Intervening Event, the Company shall deliver to Parent an additional Company Notice consistent with that described in clause (2) of this proviso and a renewed notice period under clause (2) of this proviso shall commence (except that the four (4)-Business Day notice period referred to in clause (2) of this proviso shall instead be equal to two (2) Business Days) during which time the Company shall be required to comply with the requirements of this Section 6.02(d) anew with respect to such additional Company Notice, including clauses (1) through (4) of this proviso.

(f) Except to the extent the Company is prohibited from giving Parent such notice by any confidentiality agreement in effect as of the date hereof, in addition to the requirements set forth in Section 6.02(b), Section 6.02(c) and Section 6.02(d), the Company shall, as promptly as reasonably practicable and in any event within one (1) Business Day after receipt thereof, advise Parent in writing of (i) any Company Takeover Proposal or any inquiry, proposal or offer that the Company Board in good faith believes could 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, and any subsequent material amendments or modifications thereto) and the identity of the Person making any such Company Takeover Proposal or inquiry, proposal or offer.

ADDITIONAL AGREEMENTS

SECTION 7.01 Access to Information; Confidentiality. During the Pre-Closing Period, 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)to its properties, books and records, Contracts and personnel, and, during such period, the Company shall use reasonable best efforts to furnish, as promptly as reasonably practicable, to Parent such information concerning its business, properties and personnel as Parent or Parent’s Representatives may reasonably request for the purpose of

58

transition planning and not for the purpose of any adverse action or dispute between the parties or their Affiliates; 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 (i) such information is subject to the terms of a confidentiality agreement with a third party entered into prior to the Agreement Date or granting such access would violate any obligations of the Company with respect to confidentiality to any third party or otherwise breach, contravene or violate, constitute a default under, or give a third party the right to terminate or accelerate an obligation under, any then effective Contract to which the Company is a party, (ii) such information relates to the applicable portions of the minutes of the meetings of the Company Board where the Company Board discussed (or is information otherwise related to) (A) 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, (B) any Company Takeover Proposal or (C) any Intervening Event, or (iii) the Company determines in good faith after consulting with counsel that affording such access or furnishing such information would reasonably be expected to jeopardize or result in a waiver of any attorney-client privilege, work product doctrine or other applicable privilege applicable to such information, violate applicable Law or result in antitrust risk for the Company; provided that the Company will use its reasonable efforts to communicate the applicable information to Parent in a way that would not violate any applicable Law, Contract or obligation or waive such a privilege. Nothing in this Section 7.01 or elsewhere in this Agreement shall be construed to require the Company or any Representatives of any of the foregoing to prepare any reports, analyses, appraisals, opinions or other information. All information exchanged or accessed pursuant to this Section 7.01 shall be subject to the confidentiality letter agreement dated November 11, 2023 between the Company and Parent, as amended (the “Confidentiality Agreement”).

SECTION 7.02 Reasonable Best Efforts; Notification; Regulatory Filings. Upon the terms and subject to the conditions set forth in this Agreement, each of the parties hereto shall, and shall cause their respective Subsidiaries to, use its reasonable best efforts to promptly take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties hereto in doing, all things necessary, proper or advisable to consummate and make effective, as promptly as reasonably practicable and in any event prior to the Outside Date, the Offer, the Merger and the other Transactions, including (i) causing each of the Offer Conditions and each of the conditions to the Merger set forth in Article VIII to be satisfied, in each case as promptly as reasonably practicable after the Agreement Date, (ii) the obtaining of all necessary or advisable actions or non-actions, waivers and consents from, the making of all necessary registrations, declarations and filings with, and the taking of all reasonable steps as may be necessary to avoid a Proceeding by, any Governmental Entity with respect to this Agreement or the Transactions, (iii) the defending or contesting of any Proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the Transactions, including seeking to have any stay or temporary restraining order entered by any court or other Governmental Entity vacated or reversed and (iv) the execution and delivery of any additional instruments necessary to consummate the Transactions and to fully carry out the purposes of this Agreement.

SECTION 7.03 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, officer, employee or agent (including as a fiduciary with respect to an employee benefit plan) 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 and Parent, 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, and Parent and the Surviving Corporation shall be bound thereby to the fullest extent available under the DGCL or other applicable Law for a period of six years from the Effective Time, and any claim made pursuant to such rights within such six-year period shall continue to be subject to this Section 7.03(a) and the rights provided under this Section 7.03(a) until full and final disposition of such claim. Parent shall cause the Surviving Corporation to perform its obligations under this Section 7.03(a).

(b) Without limiting Section 7.03(a) or any rights of any Indemnified Party pursuant to any indemnification agreement set forth on Section 7.03(b) of the Company Disclosure Letter, from and after the Offer Closing 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, officer, employee or agent (including as a fiduciary with respect to an employee benefit plan) of the Company, any of its former 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, Parent shall or shall cause the Surviving Corporation to 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. Parent shall, and shall cause the Surviving Corporation to, 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 otherwise provided in an indemnification agreement set forth in the Company Disclosure Letter. Parent and the Surviving Corporation shall not settle, compromise or consent to the entry of any

60

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. Parent and the Surviving Corporation’s obligations under this Section 7.03(b) shall continue in full force and effect for the period beginning upon the Offer Closing 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.

(c) At or prior to the Effective Time, following good faith consultation with Parent, the Company shall 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 Offer Closing Time and ending six years from the Effective Time (the “D&O Tail Policies”), 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 250% 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”) and the full cost of such “tail” insurance policies shall be included as Transaction Expenses. 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 Offer Closing 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 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; provided, further, that if the annual premium of such insurance coverage exceeds such Maximum Amount, Parent or the Surviving Corporation shall be obligated to obtain the maximum amount of coverage available for the Maximum Amount, but in such case shall purchase coverage as favorable to the Indemnified Parties as is available for the Maximum Amount as long as such substitution does not result in gaps or lapses of coverage with respect to matters occurring at or prior to the Effective Time.

(d) In the event that (i) Parent or the Surviving Corporation (or any of their respective 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 of Parent or the Surviving Corporation, as applicable, expressly assume the obligations set forth in this Section 7.03.

61

(e) From and after the Offer Closing Time, the obligations of Parent and the Surviving Corporation under this Section 7.03 shall survive the consummation of the Merger and shall not be terminated or modified in such a manner as to adversely affect any Indemnified Party to whom this Section 7.03 applies without the written consent of such affected Indemnified Party. The provisions of this Section 7.03 are, from and after the Offer Closing 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.

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 and that the press release to be issued at the Merger Closing shall state the Cash Amount as finally determined in accordance with Section 2.01(c).

SECTION 7.06 Tax Matters.

(b) In the case of any taxable period that includes (but does not end on) the Merger Closing Date (a “Straddle Period”), (i) the amount of any property and similar ad valorem Taxes of the Company for a Straddle Period which relate to the Pre-Closing Tax Period shall be deemed to be the amount of such Tax for the entire taxable period multiplied by a fraction the numerator of which is the number of days in the taxable period ending on (and including) the Merger Closing Date and the denominator of which is the number of days in the Straddle Period, and (ii) the amount of any other Taxes of the Company for the Pre-Closing Tax Period shall be determined based on an interim closing of the books as of the close of business on the Merger Closing Date. For purposes of the preceding sentence, exemptions, credits, allowances or deductions that are calculated on an annual basis (including depreciation and amortization deductions computed as if the Merger Closing Date was the last day of the Straddle Period) shall be allocated between the portion of the Straddle Period ending on the Merger Closing Date and the portion of the Straddle Period thereafter in proportion to the number of days in each such portion.

SECTION 7.07 Stockholder Litigation. During the Pre-Closing Period, subject to execution of a customary joint defense agreement and the preservation of the attorney-client or other applicable privilege, protection under the work product or other doctrine and protection of confidential information and except if the Company Board has made an Adverse Recommendation Change, 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 Proceedings commenced, or to the knowledge of the Company, threatened in writing, by or on behalf of one or more stockholders of the Company, against the Company and its directors relating to any Transaction, and the Company shall give reasonable and good faith consideration to any comments proposed by Parent. In no event shall the Company enter into, agree to or publicly disclose any settlement with respect to such Proceedings without Parent’s consent, such consent not to be unreasonably withheld, delayed or conditioned, except (i) to the extent such settlement is fully covered by the Company’s insurance policies (other than any applicable deductible) or (ii) such settlement relates solely to the provision of additional disclosure in the Schedule 14D-9, but, in each case, only if such settlement would not result in the imposition of any restriction on the business or operations of the Company or its Affiliates. The Company shall notify Parent promptly of the commencement or written threat of any Proceedings of which it has received notice or become aware and shall keep Parent promptly and reasonably informed regarding any such Proceedings.

Nothing in the foregoing shall be interpreted to require the Company Board (or a duly authorized committee thereof) to take any action that would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law or following an Adverse Recommendation Change. Neither Parent, Merger Sub nor the Company shall take any action that would cause this Agreement, the Merger, the Offer or the other transactions contemplated by this Agreement to be subject to the requirements imposed by any such Takeover Laws; provided, however, that nothing in the foregoing shall be interpreted to require the Company or the Company Board (or a duly authorized committee thereof) to refrain from taking any action that would reasonably be expected to be inconsistent with the fiduciary duties of the Company Board under applicable Law or any other action following an Adverse Recommendation Change.

TERMINATION, AMENDMENT AND WAIVER

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

66

(b) by either Parent or the Company:

(i) if (A) the Offer Closing Time shall not have occurred on or before 11:59 p.m., Eastern time, on February 4, 2026 (the “Outside Date”) or (B) the Offer shall have expired or been terminated and have not been extended in accordance with its terms and in accordance with this Agreement without Merger Sub having accepted for payment any shares of the Company Common Stock tendered in the Offer; 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 (in the case of the foregoing clause (A)) or the failure of Merger Sub to accept for payment any shares of the Company Common Stock tendered in the Offer (in the case of the foregoing clause (B)) is primarily due to a material breach of this Agreement by such party; or

(c) by Parent, if the Company breaches or fails to perform any of its representations, warranties or covenants 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 an Offer Condition 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 ▇▇▇▇▇▇ and Merger Sub are not then in material breach of this Agreement;

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

(g) by the Company, if (i) (x) Parent or Merger Sub breaches any of its representations or warranties contained in this Agreement, which breach had or would reasonably be expected to, individually or in the aggregate with all such other breaches, result in a Parent Material Adverse Effect or (y) Parent or Merger Sub breaches or fails to perform any of its covenants contained in this Agreement in any material respect, and (ii) the applicable breach or failure to perform cannot be or has not been cured prior to the earlier of (x) thirty (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, in each case, that the Company is not then in material breach of this Agreement; or

67

(h) by the Company, if (i) the Company Board authorizes the Company to terminate this Agreement to enter into a definitive written agreement with respect to a Superior Company Proposal, (ii) the Company Board have complied in all material respects with their 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.

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, 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 the 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. Nothing herein shall relieve any party or parties hereto, as applicable, from any liability or damage resulting from any fraud or Willful Breach of this Agreement that occurs prior to such termination (which liability or damages the parties acknowledge and agree shall not be limited to reimbursement of out-of-pocket fees, costs or expenses incurred in connection with the transactions contemplated hereby, and such party shall have the right to seek damages based on loss of the economic benefit of the transactions contemplated by this Agreement to the Company and the Company Stockholders). The parties hereto acknowledge and agree that, to the extent Parent or Merger Sub is required to pay damages in connection with the termination of this Agreement that exceeds the Company’s expenses or out-of-pocket costs incurred in connection with this Agreement and the transactions contemplated hereby, including any disputes related thereto, such excess represents an amount of damages payable in respect of losses suffered by the Company and by Persons who are Company Stockholders as of the date on which this Agreement is terminated in respect of Company Shares

68

SECTION 9.03 Termination Fees.

(a) The Company shall pay to Parent a fee equal to $2,475,000 (the “Company Termination Fee”) if:

(i) the Company terminates this Agreement pursuant to Section 9.01(h) (Superior Company Proposal);

(ii) Parent terminates this Agreement pursuant to Section 9.01(d) (Adverse Recommendation Change);

(iii) (A) after the Agreement Date, a bona fide Company Takeover Proposal is publicly proposed or announced or shall have become publicly known or otherwise communicated to management of the Company or the Company Board, and such Company Takeover Proposal is not publicly withdrawn or, if not publicly proposed or announced, communicated to the Company Board or management, is not withdrawn in the case of this Agreement being subsequently terminated pursuant to Section 9.01(b)(i) (Outside Date) and the Minimum Tender Condition has not been satisfied prior to such termination (provided, that the conditions to the Offer set forth in clause (i) of Schedule 1 are satisfied at the time of such termination), prior to the date that is two (2) Business Days prior to the final expiration date of the Offer, (B) this Agreement is terminated by either Parent or the Company pursuant to Section 9.01(b)(i) (Outside Date) (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) (Outside Date)), and (C) within twelve (12) months after such termination, the Company consummates any Company Takeover Proposal or the Company enters into a definitive agreement with respect to any Company Takeover Proposal that is subsequently consummated.

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 all references to 20% shall be deemed references to 50%. 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, and as a condition to the effectiveness of, such termination of this Agreement, (2) in the case of clause (ii), within two (2) Business Days after the date of such termination of this Agreement and (3) in the case of clause (iii), within two (2) 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 or the Expense Reimbursement Payment 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) The Company shall pay to Parent an expense reimbursement payment equal to the reasonable and documented out-of-pocket fees and expenses incurred by or on behalf of Parent or its Affiliates in connection with the transactions contemplated by this Agreement and the CVR Agreement up to a maximum of $990,000 (the “Expense Reimbursement Payment”) if Parent terminates this Agreement pursuant to Section 9.01(e) (Minimum Cash Condition).

(c) Acceptance by Parent of the Company Termination Fee due under Section 9.03(a)(i) shall constitute acceptance by Parent of the validity of any termination of this Agreement under Section 9.01(h) (Superior Company Proposal). In the event the Company Termination Fee or the Expense Reimbursement Payment described in this Section 9.03 is paid to Parent in accordance with Section 9.03(a) or Section 9.03(b), such Company Termination Fee or Expense Reimbursement Payment shall be deemed to be liquidated damages for any and all losses

69

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 any Willful Breach of this Agreement. If the Company fails to pay in a timely manner the Company Termination Fee or the Expense Reimbursement Payment due pursuant to Section 9.03(a) or Section 9.03(b) and, in order to obtain such payment, Parent makes a claim that results in a judgment for the Company Termination Fee or the Expense Reimbursement Payment, the Company shall pay to Parent its reasonable and documented costs and expenses (including reasonable and documented attorneys’ fees and expenses) in connection with such suit, together with interest on the Company Termination Fee or the Expense Reimbursement Payment (as applicable) at the prime rate as published in The Wall Street Journal in effect on the date such payment was required to be made through the date such payment was actually received.

(d) 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 Effective Time; provided, that following the Offer Closing Time, this Agreement may not be amended in any manner that causes the Merger Consideration to differ from the Offer Price.

(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.

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 or Merger Sub, action by its Board of Directors, and in the case of the Company, action by the Company Board or the duly authorized designee of the Company Board. 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 (e.g., DocuSign or Adobe Sign) 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), the CVR Agreement (including all Exhibits, Annexes or Schedules thereto), the Support Agreements (including all Exhibits, Annexes or Schedules thereto) and the Confidentiality Agreement (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 7.03, are not intended to confer upon any Person other than the parties hereto any rights or remedies, provided, that the Company shall have the right, on behalf of the Company Stockholders (each of whom 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(a) or, if specific performance is not sought or granted as a remedy, damages in accordance with this Agreement (which may include the benefit of the bargain lost by such Company Stockholders) 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 Company Stockholders 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 the sole and exclusive right to do so, as agent for such Company Stockholders. Notwithstanding clause (ii) of the immediately preceding sentence, 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, and the provisions of Section 3.10 shall be enforceable by holders of awards under the Company Stock Plans.

(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-

72

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; 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 or Parent 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 Company Stockholders 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.

73

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 the Buyer Entities 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 any termination of this Agreement or 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 twenty (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.

74

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 (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.

SECTION 10.12 Parent Guarantee. Parent agrees to take all action necessary to cause the Merger Sub or the Surviving Corporation, as applicable, and, during the period between the Offer Closing Time and the Effective Time, to perform all of its agreements, covenants and obligations under this Agreement. Parent unconditionally guarantees to the Company the full and complete performance by the Merger Sub or the Surviving Corporation, as applicable, of its respective obligations under this Agreement and shall be liable for any breach of any representation, warranty, covenant or obligation of the Merger Sub or the Surviving Corporation, as applicable, under this Agreement. Parent hereby waives diligence, presentment, demand of performance, filing of any claim, any right to require any proceeding first against Merger Sub or the Surviving Corporation, as applicable, protest, notice and all defenses and demands whatsoever in connection with the performance of its obligations set forth in this Section 10.12. Parent shall not have any right of subrogation, reimbursement or indemnity whatsoever, nor any right of recourse to security for any of the agreements, covenants and obligations of Merger Sub or the Surviving Corporation under this Agreement.

Offer Conditions

Notwithstanding any other term of the Offer or the Agreement, the Buyer Entities shall not be required 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 the Buyer Entities’ obligation to pay for or return tendered shares of the Company Common Stock promptly after the termination or withdrawal of the Offer), pay for any shares of the Company Common Stock tendered pursuant to the Offer (and not theretofore accepted for payment or paid for) unless 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 the 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, represent at least one share of Company Common Stock more than 50% of the number of Company Common Stock that are then issued and outstanding as of the expiration of the Offer (such condition, the “Minimum Tender Condition”).

With respect to any payments to be made under Section 2.4 below, the Rights Agent will accomplish the payment to any former street name holders of Company Common Stock by sending one lump payment to DTC. The Rights Agent will have no responsibilities whatsoever with regard to the distribution of payments by DTC to such street name holders. Upon a written request of the Acting Holders or the Representative to the Buyer Entities, the Buyer Entities will cause the Rights Agent to make available to the Representative, as applicable, a list of the other Holders, the number of CVRs held by each Holder, the contact information, including email address, maintained by the Rights Agent with respect to each Holder and such other information relating to this Agreement as may be reasonably requested by the Representative and is information that is typically stored by a rights agent in accordance with general industry practices for similar types of engagements.

(c) Subject to the restrictions on transferability set forth in Section 2.2 and subject to the Rights Agent’s bona fide procedures to validate the identity of a Holder, every request made to transfer a CVR must be in writing and accompanied by a written instrument of transfer, in form reasonably satisfactory to the Rights Agent pursuant to its guidelines, duly executed by the Holder thereof, the Holder’s attorney duly authorized in writing, the Holder’s personal representative duly authorized in writing, or the Holder’s survivor (with written documentation evidencing such Person’s status as the Holder’s survivor), and setting forth in reasonable detail the circumstances relating to the transfer. Upon receipt of such written notice and proper validation of the identity of such Holder, the Rights Agent will, subject to its reasonable determination that the transfer instrument is in proper form and the transfer otherwise complies with the other terms and conditions of this Agreement (including the provisions of Section 2.2), register the transfer of the CVRs in the CVR Register. As a condition of such transfer, the Buyer Entities and the Rights Agent may require a transferring Holder or its transferee to pay to the applicable Governmental Body any transfer, stamp, documentary, registration, or other similar Tax or governmental charge that is imposed in connection with any such registration of transfer. The Rights Agent shall have no duty or obligation to take any action under any section of this Agreement that requires the payment by a Holder of a CVR of such applicable Taxes or charges unless and until the Rights Agent is reasonably satisfied that all such Taxes or charges have been paid or that such Taxes or charges are not applicable. All duly transferred CVRs registered in the CVR Register will be the valid obligations of the Buyer Entities and will entitle the transferee to the same benefits and rights under this Agreement as those held immediately prior to the transfer by the transferor. No transfer of a CVR will be valid until registered in the CVR Register in accordance with this Agreement.

(d) A Holder may make a written request to the Rights Agent to change such ▇▇▇▇▇▇’s address of record in the CVR Register. The written request must be duly executed by the Holder. Upon receipt of such written notice and proper validation of the identity of such ▇▇▇▇▇▇, the Rights Agent will promptly record the change of address in the CVR Register.

Section 2.4 Payment Procedures: Notices.

(a) If a Legacy Assets Transaction Agreement is entered into during the Legacy Assets Transaction Period, then the Buyer Entities shall promptly deliver to the Rights Agent (with a copy to the Representative) written notice indicating that a Legacy Assets Transaction Agreement has been entered into and a copy of the Legacy Assets Transaction Agreement and any ancillary agreements thereto.

(b) On or prior to each CVR Payment Date and subject to Section 4.2, the Buyer Entities shall deliver to the Rights Agent (with a copy to the Representative) (i) written notice indicating that (A) the Holders are entitled to receive one or more payments with respect to CVR Proceeds; (B) the source and trigger event for such payment of CVR Proceeds; and (C) if applicable, (x) a detailed calculation of Gross Proceeds (including any calculations and/or supporting documentation applicable to any allocation determination for consideration related or

10

not related to a Legacy Asset), Net Proceeds and any Permitted Deductions used to calculate such Legacy Assets Transaction Proceeds with reasonable supporting detail for such Permitted Deductions or (y) a detailed calculation of any Legacy Receivable Amount, with reasonable supporting documentation with respect to any component thereof, including but not limited to any interest accrued or Savings (each such notice, a “CVR Payment Notice”), (ii) a letter of instruction setting forth, for each CVR, the CVR Payment Amount with respect thereto (including each component included in the calculation thereof) and (iii) any other letter of instruction reasonably required by the Rights Agent. On or prior to any CVR Payment Date and subject to Section 4.2, the Buyer Entities shall deliver to the Rights Agent the CVR Payment Amounts required by Section 4.2. All amounts delivered by the Buyer Entities hereunder shall be delivered in U.S. dollars. For the avoidance of doubt, the Buyer Entities shall have no further liability in respect of the relevant CVR Payment Amount upon delivery of such CVR Payment Amount in accordance with this Section 2.4(b) and the satisfaction of each of the Buyer Entities’ obligations set forth in this Section 2.4(b) and Section 2.6. With respect to cash deposited by the Buyer Entities with the bank or financial institution designated by the Rights Agent (which shall be ▇▇▇▇▇ Fargo, U.S. Bank or another bank or financial institution of substantially equivalent national reputation and financial standing), the Rights Agent agrees to cause such bank or financial institution to establish and maintain a separate demand deposit account, therefor in the name of the Rights Agent for the benefit of the Buyer Entities. The Rights Agent will only draw upon cash in such account(s) as required from time to time in order to make payments as required under this Agreement and any applicable Tax withholding payments pursuant to Section 2.6(b) herein. The Rights Agent shall have no responsibility or liability for any diminution of funds that may result from any deposit or investment made by the Rights Agent in accordance with this paragraph, including any losses resulting from a default by any bank, financial institution or other third party, in the absence of fraud, bad faith or willful misconduct by or on behalf of the Rights Agent. The Rights Agent may from time to time receive interest, dividends or other earnings in connection with such deposits. The Rights Agent shall not be obligated to pay such interest, dividends or earnings to the Buyer Entities, the Representative, any Holder or any other party. The Rights Agent is acting as an agent hereunder and is not a debtor of the Buyer Entities in respect of cash deposited hereunder. For the avoidance of doubt, the Buyer Entities and Representative acknowledge that (i) the Rights Agent is not a bank or a trust company, (ii) the Rights Agent is not acting in any sort of capacity as an “escrow” or similar agent hereunder, and (iii) nothing in this Agreement shall be construed as requiring the Rights Agent to perform any services that would require registration with any governmental authority as a bank or a trust company.

(c) The Rights Agent will promptly, and in any event within ten (10) Business Days after receipt of the CVR Payment Notice as well as any letter of instruction reasonably required by the Rights Agent, send each Holder at its registered address a copy of the CVR Payment Notice (at the Buyer Entities’ sole cost and expense) and, following the applicable CVR Payment Date, promptly (or, with respect to any Equity Award CVRs, to the extent required to be exempt from Section 409A of the Code, on or prior to the last date within the applicable “short-term deferral” period as set forth in Treasury Regulation Section 1.409A-1(b)(4)) pay the CVR Payment Amount (i) to each of the Holders (other than Holders who received Equity Award CVRs) by check mailed to the address of each Holder as reflected in the CVR Register as of the close of business on the CVR Payment Date and (ii) with respect to Holders who received Equity Award CVRs, through the payroll system, or any successor payroll system, of Parent or any of its Affiliates, including the Company.

11

(d) Any portion of the CVR Payment Amount that remains undistributed to a Holder six (6) months after the date of the delivery of the applicable CVR Payment Date will be delivered by the Rights Agent to the Buyer Entities, upon demand, and any Holder will thereafter look only to the Buyer Entities for payment of the CVR Payment Amount, without interest, but such Holder will have no greater rights against the Buyer Entities than those accorded to general unsecured creditors of the Buyer Entities under applicable Law.

(e) None of the Buyer Entities, any of its Affiliates, or the Rights Agent will be liable to any Person in respect of the CVR Payment Amount delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If, despite the Buyer Entities’, any of its Affiliates’ or the Rights Agent’s commercially reasonable efforts to deliver the CVR Payment Amount to the applicable Holder, the CVR Payment Amount has not been paid prior to two (2) years after the applicable CVR Payment Date (or immediately prior to such earlier date on which the CVR Payment Amount would otherwise escheat to or become the property of any Governmental Body), the CVR Payment Amount will, to the extent permitted by applicable Law, become the property of the Buyer Entities, free and clear of all claims or interest of any Person previously entitled thereto. In addition to and not in limitation of any other indemnity obligation herein, the Buyer Entities agree to indemnify and hold harmless the Rights Agent with respect to any liability, penalty, cost or expense the Rights Agent may incur or be subject to in connection with transferring such property to the Buyer Entities.

Section 2.5 Calculation of Final Net Cash.

(a) On the tenth (10th) Business Day before the Final Net Cash Determination Date, Parent shall deliver to the Representative a schedule (the “Final Net Cash Schedule”) setting forth, in reasonable detail, Parent’s good faith, estimated calculation of Final Net Cash (the “Final Net Cash Calculation”) as of the close of business on the Final Net Cash Determination Date (the “Final Net Cash Determination Time”). Parent shall make available to the Representative, as reasonably requested by the Representative, the work papers and back-up materials used or any other relevant information useful in preparing the Final Net Cash Schedule, including close-out memos or other forms of written affirmation from vendors that either no more money is due or an amount of money is due that is reflected on the Final Net Cash Schedule. If reasonably requested by the Representative, reasonable access to Parent’s and the Surviving Corporation’s accountants and counsel at reasonable times and upon reasonable notice will be provided by Parent in order to permit the Representative to review the Final Net Cash Calculation. The Final Net Cash Calculations shall include Parent’s determination, as of the Final Net Cash Determination Time, of the Cash Amount and each component thereof.

(b) The Representative shall have the right to dispute any part of the Final Net Cash Calculation by delivering a Dispute Notice to that effect to Parent on or prior to 11:59 p.m., Eastern Time, on the fifth (5th) Business Day following the Representative’s receipt of the Final Net Cash Schedule (the “Response Time”), which Dispute Notice shall identify in reasonable detail the nature and amounts of any proposed revisions to the proposed Final Net Cash Calculation and shall be accompanied by a reasonably detailed explanation for the basis for such revisions.

12

(c) If, on or prior to the Response Time, the Representative notifies Parent in writing that it has no objections to the Final Net Cash Calculation or if the Representative fails to deliver a Dispute Notice prior to the Response Time, then the Final Net Cash Calculation as set forth in the Final Net Cash Schedule shall be deemed to have been finally determined for purposes of this Agreement and shall represent the Final Net Cash at the Final Net Cash Determination Time for purposes of this Agreement.

(d) If the Representative delivers a Dispute Notice on or prior to the Response Time, then Parent and the Representative shall promptly (and in no event later than one (1) Business Day thereafter) meet and attempt in good faith to resolve the disputed item(s) and negotiate an agreed-upon determination of the Final Net Cash, which agreed upon Final Net Cash amount shall be deemed to have been finally determined for purposes of this Agreement and shall represent the Final Net Cash at the Final Net Cash Determination Time for purposes of this Agreement.

(e) If Parent and the Representative are unable to negotiate an agreed-upon determination of Final Net Cash as of the Final Net Cash Determination Time pursuant to this Section 2.5 within three (3) Business Days after delivery of the Dispute Notice (or such other period as Parent and the Representative may mutually agree upon), then any remaining disagreements as to the calculation of Final Net Cash shall be referred to for resolution to the Accounting Firm. Parent and the Representative shall promptly deliver to the Accounting Firm the work papers and back-up materials used in preparing the Final Net Cash Schedule and the Dispute Notice, and Parent and the Representative shall use commercially reasonable efforts to cause the Accounting Firm to make its determination within three (3) Business Days of accepting its selection. Parent and the Representative shall be afforded the opportunity to present to the Accounting Firm any materials related to the unresolved disputes and to discuss the issues with the Accounting Firm; provided that no such presentation or discussion shall occur without the presence of each of Parent and the Representative. The determination of the Accounting Firm shall be limited to the disagreements submitted to the Accounting Firm. The determination of the amount of Final Net Cash made by the Accounting Firm shall be made in writing delivered to each of Parent and the Representative, shall be final and binding on Parent and the Representative and shall (absent manifest error) be deemed to have been finally determined for purposes of this Agreement and to represent the Final Net Cash at the Final Net Cash Determination Time for purposes of this Agreement. The fees and expenses of the Accounting Firm shall be allocated between Parent and the Representative in the same proportion that the disputed amount of the Final Net Cash that was unsuccessfully disputed by such party (as finally determined by the Accounting Firm) bears to the total disputed amount of the Final Net Cash amount.

Section 2.6 Tax Matters.

(a) Except to the extent any portion of the CVR Payment Amount is required to be treated as interest pursuant to applicable Law, the Buyer Entities and the Representative intend that, for all U.S. federal and applicable state and local income tax purposes, (i) the CVRs received in respect of Company Common Stock (which for avoidance of doubt does not include the Equity Award CVRs) will be treated as additional consideration paid with respect to such Company Common Stock in connection with the Offer or the Merger, as the case may be and (ii) any CVR Payment Amount paid in respect of any Equity Award CVR will be treated as compensation in the year in which the CVR Payment Amount is made (and not upon the receipt of such CVR). The Buyer Entities and its Affiliates (including the Company after the Merger) shall

13

(and the Buyer Entities shall instruct the Rights Agent to) report for all Tax purposes in a manner consistent with the foregoing (including as relates to any interest), and none of the parties will take any position to the contrary on any U.S. federal, state and local Tax Returns or for other U.S. federal and applicable state and local income tax purposes, unless otherwise required by applicable Law or a “determination” within the meaning of Section 1313(a) of the Code (or a similar determination under applicable state or local Law).

(b) In addition to any Permitted Deductions, the Buyer Entities and its Affiliates (including the Company after the Merger) and the Rights Agent shall be entitled to, and the Buyer Entities will instruct the Rights Agent or its applicable Affiliate to, deduct and withhold, or cause to be deducted or withheld, from each CVR Payment Amount or any other amounts otherwise payable pursuant to this Agreement such amounts as may be required to be deducted and withheld therefrom under applicable Law. With respect to Holders who received Equity Award CVRs, any such withholding may be made, or caused to be made, by the Buyer Entities through the payroll system or any successor payroll system of the Buyer Entities or any of its Affiliates, including the Company. Prior to making (or causing to be made) any Tax deduction or withholding pursuant to this Section 2.6(b), the Rights Agent will (and the Buyer Entities shall instruct the Rights Agent to) provide the opportunity for the Holders to provide properly completed and duly executed Internal Revenue Service Forms W-9 or applicable Form W-8, as applicable, or any other reasonably appropriate forms or information from Holders in order to eliminate or reduce withholding. The Rights Agent shall and the Buyer Entities shall (or shall cause its applicable Affiliate to), as applicable, promptly and timely remit, or cause to be promptly and timely remitted, any amounts withheld in respect of Taxes to the appropriate Governmental Body. To the extent any amounts are so deducted and withheld and properly remitted, such amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of whom such deduction and withholding was made. Promptly following such withholding, the Buyer Entities will (or will instruct its applicable Affiliate or the Rights Agent to) deliver to the Person to whom such amounts would otherwise have been paid reasonably acceptable evidence of such withholding.

(c) The Buyer Entities and the Representative intend that each payment provided under this Agreement with respect to an Equity Award CVR (the “Payments”) is a separate “payment” for purposes Section 1.409A-2(b)(2)(i) of the U.S. Treasury Regulations. For the avoidance of doubt, the Buyer Entities and the Representative intend that the Payments satisfy, to the greatest extent possible, the exemption from the application of Section 409A of the Code and the Treasury Regulations and other guidance issued thereunder and any state law of similar effect (collectively “Section 409A”) provided under Treasury Regulations Section 1.409A-1(b)(4) and, to the extent not so exempt, that the Payments comply, and this Agreement be interpreted to the greatest extent possible, as consistent with Treasury Regulations Section 1.409A-3(i)(5)(iv)(A)—that is, as “transaction-based compensation.” To the extent this Agreement (and any definitions hereunder), or any payments hereunder, are not exempt, they shall be construed in a manner that complies with Section 409A, including by reason of satisfying the “transaction-based compensation” provisions thereunder, including the five-year post-Closing payment limitation therein, and shall incorporate by reference all required definitions and payment terms. Notwithstanding the foregoing, none of the Buyer Entities, the Company or their respective board, or any of their respective representatives make any representation or warranty and will have no liability to a Holder or transferee or any other Person if any payments under any provisions of this

14

Agreement are determined to constitute deferred compensation under Section 409A of the Code (or any similar U.S. state tax law) that are subject to certain additional federal, state or other taxes. The Buyer Entities may provide each recipient of an Equity Award CVR with a notice or award agreement setting forth the terms and condition of the Holder’s entitlement to payments under such Equity Award CVR in accordance with the terms of this Agreement. The Rights Agent makes no representations or warranties with respect to tax treatment of the CVRs. None of the Rights Agent, its Affiliates or the services provided by the Rights Agent hereunder are intended to provide legal, tax or financial advice.

Section 2.7 No Voting, Dividends or Interest; No Equity or Ownership Interest in Parent or any of its Affiliates.

(a) The CVRs will not have any voting or dividend rights, and interest will not accrue on any amounts payable on the CVRs to any Holder.

(b) The CVRs will not represent any equity or ownership interest in Parent, any constituent corporation party to the Merger or any of their respective Affiliates. It is hereby acknowledged and agreed that a CVR shall not constitute a security of Parent.

(c) Each Holder, by virtue of the approval of the Merger and this Agreement by the Initial Holders or the receipt of any consideration in connection with the Merger, and without any further action of any of the Holders or the Company, acknowledges and agrees to the appointment and authority of the Representative, as of the Offer Closing Time, to act as the exclusive representative, agent and true and lawful attorney-in-fact of such ▇▇▇▇▇▇ and all Holders as set forth in this Agreement, which shall include the power and authority of the Representative to (i) incur and pay expenses on behalf of the Holders as required hereunder, (ii) exercise the audit rights under Section 4.4, and (iii) take or refrain from taking the actions specified herein and any other actions relating to the subject matter of this Agreement reasonably deemed necessary or appropriate by the Representative. Notwithstanding the foregoing, the Representative shall have no obligation to act on behalf of the Holders, except as expressly provided herein and in the Representative Engagement Agreement, and for the avoidance of doubt, the Representative shall have no obligations of the Representative under the Merger Agreement or any ancillary agreement, schedule or exhibit thereto other than this Agreement. All actions taken by the Representative in accordance with the terms of this Agreement and the Representative Engagement Agreement shall be binding upon each Holder and such ▇▇▇▇▇▇’s successors as if expressly confirmed and ratified in writing by such ▇▇▇▇▇▇, and all defenses which may be available to any Holder to contest, negate or disaffirm any such action of the Representative taken in good faith under this Agreement or the Representative Engagement Agreement are waived. Each Holder agrees that such ▇▇▇▇▇▇ will not threaten, bring, commence, institute, maintain, prosecute or voluntarily aid any action, which challenges the validity of or seeks to enjoin the operation of any provision of this Agreement, including the provisions relating to the authority of the Representative to act on behalf of such Holder and all Holders as set forth in this Agreement. The Representative shall be entitled to: (A) rely upon the CVR Register and associated list of Holders, (B) rely upon any signature reasonably believed by it to be genuine, and (C) reasonably assume that a signatory has proper authorization to sign on behalf of the applicable Holder or other party.

15

(d) Parent, its board of directors and its officers and Affiliates will not be deemed to have any fiduciary or similar duties to any Holder by virtue of this Agreement.

(e) It is hereby acknowledged and agreed that the CVRs and the possibility of any payment hereunder with respect thereto are highly speculative and subject to numerous factors outside of Parent’s control, and there is no assurance that Holders will receive any payments under this Agreement or in connection with the CVRs. The Parties acknowledge that it is possible that no Legacy Assets Transaction will occur during the Legacy Assets Transaction Period and that there will not be any Gross Proceeds that may be the subject of a CVR Payment Amount.

Section 2.8 Ability to Renounce or Abandon CVR. Notwithstanding anything to the contrary contained herein, any Holder or ▇▇▇▇▇▇’s successor or assign pursuant to a Permitted CVR Transfer may, at any time, at such Holder’s option, agree to renounce, in whole or in part, its rights under this Agreement and abandon all of such Holder’s remaining rights in a CVR by transferring such CVR to the Buyer Entities without consideration therefor, effected by written notice to the Rights Agent, the Representative and the Buyer Entities, which renouncement and abandonment notice, if given, shall be irrevocable. Nothing in this Agreement shall prohibit the Buyer Entities or any of its Affiliates from offering to acquire or acquiring any CVRs for consideration from the Holders, in private transactions or otherwise, in its sole discretion. Any CVRs acquired by the Buyer Entities or any of its Affiliates shall be automatically deemed extinguished and no longer outstanding for purposes of the definition of Acting Holders and ARTICLE VI and Section 6.3 hereunder.

ARTICLE III

(d) the Rights Agent may engage and consult with counsel of its selection and the written advice of such counsel or any opinion of counsel will, in the absence of bad faith, gross negligence, fraud or willful misconduct (in each case as determined by a court of competent jurisdiction), provide full and complete authorization and protection to the Rights Agent and the Rights Agent shall be held harmless by Parent in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

(n) no provision of this Agreement shall require the Rights Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of its rights if there shall be reasonable grounds for believing that repayment of such funds or adequate indemnification against such risk or liability is not reasonably assured to it.

Section 3.3 Resignation and Removal; Appointment of Successor.

(a) The Rights Agent may resign at any time by giving written notice thereof to Parent (with a copy to the Representative) specifying a date when such resignation will take effect, which notice will be sent at least sixty (60) days prior to the date so specified but in no event will such resignation become effective until a successor Rights Agent has been appointed. The Representative shall have the right to remove the Rights Agent at any time by specifying a date when such removal will take effect but no such removal will become effective until a successor Rights Agent has been appointed. Notice of such removal will be given by the Representative to Rights Agent (with a copy to Parent), which notice will be sent at least sixty (60) days prior to the date so specified.

18

(b) If the Rights Agent provides notice of its intent to resign, is removed pursuant to Section 3.3(a) or becomes incapable of acting, Parent and the Representative, acting in concert, will, as soon as is reasonably possible, appoint a qualified successor Rights Agent who, unless otherwise consented to in writing by the Acting Holders, shall be a stock transfer agent of national reputation or the corporate trust department of a commercial bank. The successor Rights Agent so appointed will, forthwith upon its acceptance of such appointment in accordance with Section 3.4, become the successor Rights Agent.

COVENANTS

Section 4.3 Discretion and Decision-Making Authority. Notwithstanding anything herein to the contrary, but subject to Parent’s obligations as set forth herein, (a) Parent and its Affiliates shall have the power and right to control all aspects of their businesses and operations (and all of their assets and products), and subject to its compliance with the terms of this Agreement, Parent and its Affiliates may exercise or refrain from exercising such power and right as it may deem appropriate and in the best overall interests of Parent and its Affiliates and its and their stockholders, rather than the interest of the Holders, and (b) following the Legacy Assets Transaction Period, the Company shall be permitted to take any action in respect of the Legacy Assets; provided, that, during the Legacy Assets Transaction period:

(a) Solely if requested in writing by the Representative, Parent shall (or shall cause its Affiliates to) enter into one or more Legacy Assets Transaction Agreements; provided, however, that Parent shall not be required to enter into a Legacy Assets Transaction Agreement if such arrangement would result in the Legacy Assets being required by GAAP to be consolidated in the financial statements of Parent following the consummation of the transactions contemplated by such Legacy Assets Transaction Agreement. For the avoidance of doubt, neither Parent nor any of its Affiliates may enter into a Legacy Assets Transaction Agreement without the prior written consent of the Representative.

(b) Parent shall (or shall cause its Affiliates to) utilize the Legacy Assets and Expense Fund to take all actions reasonably necessary or advisable (subject to the prior written consent of the Representative) to maintain, advance and maximize the value of the Legacy Assets and pursue one or more Legacy Assets Transactions (collectively, the “Purpose”), including but not limited to (i) the transfer of the Legacy Assets out of the Company and into a newly formed special purpose vehicle or other similar structure (“Parent NewCo”), (ii) the issuance of any amount of new equity interests in Parent NewCo to bona fide third party investors and financing sources (iii) the issuance of any amount of new incentive awards to Parent NewCo employees and/or consultants for services to Parent NewCo for the advancement of the Legacy Assets and pursuit of Legacy Assets Transactions, and (iii) any amount of new equity interests in Parent NewCo to maintain, retain or improve the intellectual property, including the license, with respect to the Legacy Assets.

(c) Parent shall not, before the expiration of the Legacy Assets Transaction Period, terminate or negatively impact the required maintenance of Legacy Assets, including by failing to preserve and maintain the Legacy Assets. Solely if requested in writing by the Representative, Parent shall terminate the Legacy Assets and wind down prosecution and maintenance costs relating to the Legacy Assets.

(d) Parent shall comply with all prosecution, maintenance and other obligations relating to the Intellectual Property Rights within the Legacy Assets required by any license or related term set forth in any Legacy Assets Transaction Agreement, to the extent such Intellectual Property Rights are contemplated by said Legacy Assets Transaction Agreement.

Section 4.4 Audit Right. Parent agrees to maintain, for at least six months after the applicable CVR Payment Date, all books and records relevant to the calculation of a CVR Payment Amount and the amount of Gross Proceeds, Net Proceeds and Permitted Deductions. Subject to reasonable advance written notice from the Representative and prior execution and delivery by it and an independent accounting firm of national reputation chosen by the Representative (the “Accountant”) of a reasonable and customary confidentiality/nonuse agreement, Parent shall permit the Representative and the Accountant, acting as agent of the Representative (on behalf of the Holders), to have access during normal business hours to the books and records of Parent as may be reasonably necessary to audit the calculation of such CVR Payment Amount, the calculation of the amount of Gross Proceeds, Net Proceeds and Permitted Deductions.

Section 4.5 Assignments. The Buyer Entities shall not, in whole or in part, assign any of its obligations under this Agreement other than in accordance with the terms of Section 6.3. At any time, the Representative may resign (in which case the Acting Holders shall promptly appoint a successor Representative (reasonably acceptable to the Buyer Entities)) and may assign any of its rights or obligations under this Agreement (or this Agreement in its entirety) to any third party (reasonably acceptable to the Buyer Entities) to serve as a successor Representative, provided, that such assignee executes a written joinder to this Agreement assuming the rights and duties of the Representative.

Section 4.6 Additional Covenants.

(a) During the Legacy Assets Transaction Period, Parent shall, and shall cause its Subsidiaries, licensees and rights transferees to, use commercially reasonable efforts to enter into one or more Legacy Assets Transaction Agreements as promptly as practicable following the Effective Time. During the Legacy Assets Transaction Period, Parent shall, and shall cause its Affiliates to, use commercially reasonable efforts to (i) preserve and maintain the Legacy Assets (including with respect to its obligations in Section 4.3), (ii) pursue any Legacy Assets Transaction required to advance the Legacy Assets and (iii) take all other actions reasonably necessary and advisable to advance and maximize the value of the Legacy Assets in connection with achieving one or more Legacy Assets Transactions. Parent shall consult with the Representative on all efforts taken by Parent and its Affiliates in compliance with Parent’s obligations under this Section 4.6(a) and Section 4.3 herein.

(b) In the event that any of the Buyer Entities desires to consummate a Change of Control prior to the final CVR Payment Date, such Buyer Entity or its successor, as applicable depending upon the structure of the Change of Control, will cause the Person acquiring the Buyer Entity to assume the Buyer Entity’s or its successor’s (as applicable depending upon the structure of the Change of Control) obligations, duties and covenants under this Agreement. No later than five (5) Business Days after the consummation of any Change of Control, the Buyer Entity will deliver to the Rights Agent an Officer’s Certificate, stating that such Change of Control complies with this Section 4.6(b) and that all conditions precedent herein relating to such transaction have been complied with.

21

(c) Until such time as the Expiration Date occurs, (i) Parent shall, and shall cause its Subsidiaries to, maintain records in the ordinary course of business pursuant to record-keeping procedures normally used by Parent and its Subsidiaries regarding its activities (including its resources and efforts) with respect to entering into Legacy Assets Transaction Agreements and (ii) to the extent Parent licenses, sells, assigns or otherwise transfers intellectual property and other rights (including, without limitation, all data, marketing authorizations and applications for marketing authorization), assets, rights, powers, privileges and Contracts, Parent will require the licensee, purchaser, assignee, or transferee, as applicable to provide the information necessary for Parent to comply with its obligations under this Agreement.

(d) Upon the reasonable written request from the Representative, and subject to the Representative executing a customary confidentiality agreement in the event the information provided would constitute material non-public information of Parent, Parent will provide (i) during the Legacy Assets Transaction Period, the Representative with a written update in reasonable detail describing the progress, status and anticipated trajectory of efforts in respect of Legacy Assets Transactions and (ii) the anticipated timing of receiving payments in respect of such Legacy Assets Transactions, in each case up to one time in a fiscal quarter of each calendar year.

(e) Parent shall, and shall cause its Affiliates, including the Company, to, until such time as this Agreement is terminated pursuant to Section 6.8, (i) comply in all material respects with their respective covenants and obligations under each Legacy Assets Transaction Agreement, and (ii) consider the interests of the Holders under this Agreement in good faith, and not take any action, or fail to take any action, the primary purpose of which is to circumvent the purpose of this Agreement and the intent of the parties, including by reducing the amount of Legacy Assets Transaction Proceeds.

(f) Neither the Representative nor (if applicable) its members, managers, directors, officers, contractors, agents and employees (collectively, the “Representative Group”), shall be liable to any Holder for any action or failure to act in connection with the acceptance or administration of the Representative’s responsibilities hereunder unless and only to the extent such action or failure to act constitutes gross negligence, fraud or willful misconduct. The Holders shall indemnify, defend and hold harmless the Representative Group from and against any and all losses, claims, damages, liabilities, fees, costs, expenses (including fees, disbursements and costs of counsel and other skilled professionals and in connection with seeking recovery from insurers), judgments, fines, amounts paid in settlement (collectively, the “Representative Expenses”) incurred without gross negligence, fraud or willful misconduct on the part of the Representative and arising out of or in connection with the acceptance or administration of its duties hereunder. Such Representative Expenses may be recovered first, from the Legacy Assets and Expense Fund, second, from any distribution of CVR Payment Amounts otherwise distributable to the Holders at the time of distribution, and third, directly from the Holders. The immunities and rights to indemnification shall survive the resignation or removal of the Representative or any termination of this Agreement. The Holders acknowledge that the Representative shall not be required to expend or risk its own funds or otherwise incur any financial liability in the exercise or performance of any of its powers, rights, duties or privileges or pursuant to this Agreement or the transactions contemplated hereby or thereby. Furthermore, the Representative shall not be required to take any action unless the Representative has been provided with funds, security or indemnities which, in its reasonable determination, are sufficient to protect the Representative against the costs, expenses and liabilities which may be incurred by the Representative in performing such actions. The powers, immunities and rights to indemnification granted to the Representative Group hereunder: (i) are coupled with an interest and shall be irrevocable and survive the death,

22

incompetence, bankruptcy or liquidation of any Holder and shall be binding on any successor thereto, and (ii) shall survive the delivery of an assignment by any Holder of the whole or any fraction of his, her or its interest in the CVR Proceeds. The Legacy Assets and Expense Fund Amount shall be held by Parent in a segregated client account and shall be used only with the consent of the Representative (A) for the Purpose and (B) for the purposes of paying directly or reimbursing the Representative for any Representative Expenses incurred pursuant to this Agreement. The Representative is not acting as a withholding agent or in any similar capacity in connection with the Legacy Assets and Expense Fund and has no tax reporting or income distribution obligations with respect to the Legacy Assets and Expense Fund. The Holders will not receive any interest on the Legacy Assets and Expense Fund and assign to the Representative any such interest. The Representative may instruct the Rights Agent to contribute funds to the Legacy Assets and Expense Fund from the CVR Payment Amounts otherwise distributable to any Holders, on a pro rata basis. As soon as reasonably determined by the Representative that the Legacy Assets and Expense Fund is no longer required to be withheld, Parent shall distribute the remaining Legacy Assets and Expense Fund, if any, to the Rights Agent for further distribution to the Holders in such proportions as though the amount of the remaining Legacy Assets and Expense Fund constituted CVR Proceeds hereunder (provided, that, any amounts remaining from the amounts contributed to the Legacy Assets and Expense Fund from the CVR Payment Amounts otherwise distributable to any Holders pursuant to the previous sentence shall first be distributed to such Holders in proportion to such Holders’ respective contributions).

Any party may specify a different address by giving notice in accordance with this Section 6.1.

Section 6.2 Notice to Holders. Where this Agreement provides for notice to Holders, such notice will be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at the Holder’s address as it appears in the CVR Register, not later than the latest date, and not earlier than the earliest date, if any, prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder will affect the sufficiency of such notice with respect to other Holders.

Section 6.3 Successors and Assigns. The Buyer Entities may assign any or all of its rights, interests and obligations hereunder in its sole discretion and without the consent of any other party, (i) to any controlled Affiliate of Parent, but only for so long as it remains a controlled Affiliate of Parent, (ii) in compliance with Section 4.6(b), or (iii) otherwise with the prior written consent of the Acting Holders (such consent not to be unreasonably withheld, conditioned or delayed), any other Person (any permitted assignee under clauses (i), (ii), or (iii), an “Assignee”), in each case provided, that the Assignee agrees to assume and be bound by all of the terms of this Agreement. Any Assignee may thereafter assign any or all of its rights, interests and obligations hereunder in the same manner as the Buyer Entities pursuant to the prior sentence. In connection with any assignment to an Assignee described in clause (i) above in this Section 6.3 and clause (ii) above in this Section 6.3, the Buyer Entities shall agree to remain liable for the performance by each Assignee of all obligations of the Buyer Entities hereunder with such Assignee substituted for the Buyer Entities under this Agreement. This Agreement will be binding upon, inure to the benefit of and be enforceable by each of the Buyer Entities’ successors and each Assignee. Subject to compliance with the requirements set forth in this Section 6.3 relating to assignments, this Agreement shall not restrict the Buyer Entities’ any Assignee’s or any of their respective successors’ ability to merge or consolidate with, or sell, issue or dispose of its stock or other equity

26

interests or assets to, any other Person. Each of the Buyer Entities’ successors and Assignees shall expressly assume by an instrument supplemental hereto, executed and delivered to the Rights Agent (with a copy to the Representative), the due and punctual payment of the aggregate CVR Proceeds and the due and punctual performance and observance of all of the covenants and obligations of this Agreement to be performed or observed by the Buyer Entities. The Rights Agent may not assign this Agreement without the Representative’s written consent, except to an affiliate of the Rights Agent in connection with a corporate restructuring or to a successor Rights Agent in accordance with the terms of this Agreement. Any attempted assignment of this Agreement or any such rights in violation of this Section 6.3 shall be void and of no effect.

Section 6.4 Benefits of Agreement. Nothing in this Agreement, express or implied, will give to any Person (other than the Rights Agent, the Representative, the Buyer Entities, the Buyer Entities’ successors and Assignees, the Holders and the Holders’ successors and assigns pursuant to a Permitted CVR Transfer) any benefit or any legal or equitable right, remedy or claim under this Agreement or under any covenant or provision herein contained, all such covenants and provisions being for the sole benefit of the foregoing. The rights of Holders and their successors and assigns pursuant to Permitted CVR Transfers are limited to those expressly provided in this Agreement. Notwithstanding anything to the contrary herein, the Representative shall not commence any action under this Agreement on behalf of or to enforce the rights of the Holders except at the direction of and with the prior written consent of the Acting Holders. Except for the rights of the Rights Agent and the Representative set forth herein, the Acting Holders will have the sole right, on behalf of all Holders, by virtue of or under any provision of this Agreement, to institute any action or proceeding with respect to this Agreement, and no individual Holder or other group of Holders will be entitled to exercise such rights. Reasonable expenditures incurred by such Holders in connection with any enforcement action hereunder may be deducted from any damages or settlement obtained prior to the distribution of any remainder to Holders generally. Holders acting pursuant to this provision on behalf of all Holders shall have no liability to the other Holders for such actions. The Representative and all Holders (including the Acting Holders) must enforce any such legal or equitable rights, remedies or claims under this Agreement against the Buyer Entities and not against the Rights Agent.

Section 6.5 Governing Law; Jurisdiction; Waiver of Jury Trial.

Each of the parties irrevocably and unconditionally (A) agrees not to commence any such action or proceeding except in the Delaware Courts, (B) agrees that any claim in respect of any such action or proceeding may

27

be heard and determined in the Delaware Courts, (C) waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the jurisdiction or laying of venue of any such action or proceeding in the Delaware Courts and (D) waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in the Delaware Courts.

(c) EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING BETWEEN THE PARTIES (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE), INCLUDING ANY COUNTERCLAIM, ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THE ACTIONS OF ANY PARTY IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT THEREOF. EACH PARTY HERETO (A) MAKES THIS WAIVER VOLUNTARILY AND (B) ACKNOWLEDGES THAT SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS CONTAINED IN THIS SECTION 6.5(C).

Section 6.6 Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement shall remain in full force and effect. Any provision of this Agreement held invalid or unenforceable only in part or degree shall remain in full force and effect to the extent not held invalid or unenforceable. The parties further agree to replace such invalid or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable provision.

Section 6.7 Counterparts and Signature. This Agreement may be executed in two or more counterparts (including by an electronic scan delivered by electronic mail), each of which shall be deemed an original but all of which together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each of the parties hereto and delivered to the other party, it being understood that the parties need not sign the same counterpart.

Section 6.8 Termination. This Agreement will be terminated and of no force or effect, the parties hereto will have no liability hereunder (other than with respect to monies due and owing by the Buyer Entities to the Rights Agent or the Representative), and no payments will be required to be made, upon the earliest to occur of (a) the mailing by the Rights Agent to the address of each Holder as reflected in the CVR Register of all CVR Payment Amounts (if any) required to be paid under the terms of this Agreement, (b) the delivery of a written notice of termination duly executed by the Buyer Entities and the Acting Holders, or (c) subject to Section 4.4, the Expiration Date (only to the extent that a Legacy Assets Transaction does not occur prior to the Expiration Date). For the avoidance of doubt and notwithstanding anything to the contrary, nothing herein shall terminate or otherwise negatively affect any of the rights or remedies of the Representative Group with respect to the Holders pursuant to this Agreement or otherwise.

Section 6.9 Entire Agreement. This Agreement, the Merger Agreement (including the schedules, annexes and exhibits thereto and the documents and instruments referred to therein) contain the entire understanding of the parties hereto and thereto with reference to the transactions and matters contemplated hereby and thereby and supersede all prior agreements, written or oral, among the parties with respect hereto and thereto.

28

Section 6.10 Legal Holiday. In the event that the CVR Payment Date shall not be a Business Day, then, notwithstanding any provision of this Agreement to the contrary, any payment required to be made in respect of the CVRs on such date need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the CVR Payment Date.

Section 6.11 Obligations of Parent. Parent shall ensure that Merger Sub, and Merger Sub shall ensure that Parent, duly perform, satisfy and discharge each of the covenants, obligations and liabilities applicable to such party under this Agreement, and Parent shall be jointly and severally liable with ▇▇▇▇▇▇ Sub for the performance and satisfaction of each of said covenants, obligations and liabilities.

This TENDER AND SUPPORT AGREEMENT (this “Agreement”), dated as of August 4, 2025, is made by and among XOMA Royalty Corporation, a Nevada corporation (“Parent”), XRA 4 Corp., a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”), and the undersigned holder (“Stockholder”) of shares of common stock, par value $0.0001 per share (the “Company Common Stock”), of HilleVax, Inc., a Delaware corporation (the “Company”). Capitalized terms used herein and not defined shall have the meanings ascribed to them in the Merger Agreement (as defined below).

WHEREAS, Stockholder is, as of the date hereof, the beneficial owner (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which meaning will apply for all purposes of this Agreement) of the number of shares of Company Common Stock set forth opposite the name of Stockholder on Schedule 1 attached hereto (all such Shares, together with any securities convertible into or exercisable or exchangeable or redeemable for Shares, and any New Shares (defined in Section 3 below), the “Shares”);

WHEREAS, Parent, Merger Sub and the Company have entered into an Agreement and Plan of Merger, dated as of August 4, 2025, by and among Parent, Merger Sub and the Company (as such agreement may be subsequently amended or modified, the “Merger Agreement”), which provides, among other things, for the Buyer Entities to commence a tender offer for all of the issued and outstanding shares of Company Common Stock (as it may be amended from time to time in accordance with the terms of the Merger Agreement, the “Offer”) and, following the completion of the Offer, the merger of Merger Sub with and into the Company, with the Company surviving that merger, on the terms and subject to the conditions set forth in the Merger Agreement (the “Merger”); and

WHEREAS, as an inducement and a condition to the willingness of ▇▇▇▇▇▇ and ▇▇▇▇▇▇ Sub to enter into the Merger Agreement, and in consideration of the substantial expenses incurred and to be incurred by them in connection therewith, Stockholder (solely in Stockholder’s capacity as a stockholder of the Company) has agreed to enter into and perform this Agreement.

NOW, THEREFORE, in consideration of, and as a condition to, ▇▇▇▇▇▇ and ▇▇▇▇▇▇ Sub entering into the Merger Agreement and proceeding with the transactions contemplated thereby, and in consideration of the expenses incurred and to be incurred by the Buyer Entities in connection therewith, the parties hereto agree as follows:

1. Agreement to Tender Shares.

(a) Subject to the terms of this Agreement, Stockholder hereby agrees that it shall irrevocably tender its Shares, or cause its Shares to be validly and irrevocably tendered, into the Offer pursuant to and in accordance with the terms of the Offer, free and clear of all Liens (as defined below) (except for Permitted Liens (as defined below)).

(b) Upon receipt of payment in full for all of its Shares pursuant to the Merger Agreement and the full and complete satisfaction of the terms of the Offer, Stockholder agrees that any and all rights incident to its ownership of Shares (including any rights to recover amounts, if any, that may be determined to be due to any stockholder or former stockholder of the Company), including but not limited to rights arising out of Stockholder’s ownership of Shares prior to the transfer of such Shares to the Buyer Entities pursuant to the Offer or pursuant to the Merger Agreement, shall be transferred to the Buyer Entities upon the transfer to the Buyer Entities of Stockholder’s Shares.

2. Termination Date. As used in this Agreement, the term “Termination Date” shall mean the earliest to occur of: (a) the Effective Time; (b) such date and time as the Merger Agreement shall be validly terminated upon the terms and subject to the conditions set forth therein; (c) an amendment of the Merger Agreement, without the prior written consent of Stockholder, in a manner that negatively or adversely affects the Offer or that decreases the amount, or changes the form, of consideration payable to any stockholder of the Company pursuant to the terms of the Merger Agreement; (d) the mutual written agreement of the parties hereto to terminate this Agreement; (e) any material breach of this Agreement or the Merger Agreement by Parent or Merger Sub; or (f) the Board approves, recommends, encourages or supports an alternative transaction in compliance with Section 6.2 of the Merger Agreement. Upon termination of this Agreement, no party shall have any further obligations or liabilities under this Agreement; provided, however, such termination shall not relieve any party from liability for any common law fraud or willful, knowing and material breach of this Agreement prior to termination hereof.

3. Additional Purchases. Stockholder agrees that any Shares of the Company (and any securities convertible into or exercisable or exchangeable or redeemable for Shares) that Stockholder purchases or with respect to which Stockholder otherwise acquires beneficial ownership (as defined in Rule 13d-3 under the Exchange Act) after the execution of this Agreement and prior to the Termination Date, including, without limitation, by the exercise of a Company Stock Option or the vesting or settlement of a Company Restricted Stock Unit (“New Shares”), shall be subject to the terms and conditions of this Agreement to the same extent as if they constituted Shares as of the date hereof and the representation and warranties in Section 5 below shall be true and correct as of the date that beneficial ownership (as defined in Rule 13d-3 under the Exchange Act) of such New Shares is acquired.

4. Agreement to Retain Shares and Other Covenants.
