SECTION 2.01 The Offer.

(a) Commencement and Term of the Offer. Provided that this Agreement shall not have been terminated in accordance with Section 9.01, subject to the terms and conditions of this Agreement, as promptly as practicable (but in no event later than ten (10) Business Days after the Agreement Date), Merger Sub shall, and Parent shall cause Merger Sub to, commence (within the meaning of the applicable rules and regulations of the SEC) the Offer at the Offer Price. The obligations of Merger Sub to, and of Parent to cause Merger Sub to, irrevocably accept for payment, and pay for, any shares of the Company Common Stock tendered pursuant to the Offer shall be subject only to the satisfaction or waiver of the conditions set forth on Exhibit A (the “Offer Conditions”). The initial expiration date of the Offer shall be at the time that is one minute following 11:59 p.m., Eastern time, on the date that is twenty (20) Business Days (determined using Rule 14d-1(g)(3) of the Exchange Act) after the date the Offer is first commenced (within the meaning of Rule 14d-2 promulgated under the Exchange Act). Merger Sub expressly reserves the right to waive, in its 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, Merger Sub shall not, and Parent shall not permit Merger Sub to, (i) reduce the number of shares of the Company Common Stock subject to the Offer, (ii) reduce the Offer Price below the Base Price Per Share, (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 (provided that the determination of the final Cash Amount pursuant to the terms of this Agreement above the Base Price Per Share shall not constitute such a change), (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. Notwithstanding the foregoing or anything to the contrary in this Agreement, unless this Agreement has been validly terminated in accordance with Section 9.01, (A) Merger Sub may elect to (and if so requested by the Company, Merger Sub shall, and Parent shall cause Merger Sub to), extend the Offer for one or more consecutive increments of such duration as requested by the Company (or if not so requested by the Company, as determined by Parent), but not more than ten (10) Business Days each (or for such longer period as may be agreed to by Parent and the Company), if (I) at the scheduled expiration date of the Offer any of the Offer Conditions (including the Minimum Tender Condition) shall not have been satisfied or waived (if permitted hereunder), until such time as such conditions shall have been satisfied or waived (if permitted hereunder), (II) at the scheduled expiration date of the Offer Section 2.01(d)(v) applies as to the determination of the Closing Net Cash and the resolution of the matters described in Section 2.01(d)(vi) has not been finalized or (III) the Company shall have consummated a Permitted Disposition subsequent to its most recent delivery of the Closing Cash Schedule, to allow for a the delivery of an updated Closing Cash Schedule pursuant to Section 2.01(d)(ii) (which updated Closing Cash Schedule shall supersede any Closing Cash Schedule previously delivered), provided that, if the Offer has previously been extended twice pursuant to this clause (III) at the Company’s request then the mutual agreement of Merger Sub and the Company shall be required for any further extension pursuant to this clause (III), and (B) Merger Sub shall, and Parent shall cause Merger Sub to, extend the Offer for the minimum period required by any rule, regulation or interpretation or position of the SEC or the staff thereof or Nasdaq, in each case that are applicable to the Offer; provided that Merger Sub shall not, and shall not be required to, extend the Offer beyond the Outside Date and, in the case of the Minimum Tender Condition being the only condition not satisfied under clause (I) of the foregoing (other than conditions that by their nature are only satisfied as of the Offer Closing Time), Parent shall not be required to cause Merger Sub to extend the Offer to a date later than the Outside Date.

13

On the terms and subject only to the conditions of the Offer and this Agreement, Merger Sub shall, and Parent shall cause Merger Sub to, 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, Parent and Merger Sub 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. The Company shall furnish to Parent and Merger Sub all information concerning the Company required by applicable Law to be set forth in the Offer Documents. Each of Parent, Merger Sub and the Company shall promptly correct any information provided by it for use in the Offer Documents if and to the extent that such information shall have become false or misleading in any material respect, and to correct any material omissions therefrom, and each of Parent and Merger Sub shall take all steps necessary to amend or supplement the Offer Documents and to cause the Offer Documents, as so amended or supplemented, to be filed with the SEC and disseminated to the holders of the Company Common Stock, in each case, as and to the extent required by applicable Law. Parent and Merger Sub shall promptly provide the Company and its counsel with copies of any written comments, and shall inform the Company and its counsel of any oral comments, that Parent, Merger Sub or their counsel may receive from the SEC or its staff with respect to the Offer Documents promptly after the receipt of such comments. Except from and after an Adverse Recommendation Change, prior to the filing of the Offer Documents (including any amendment or supplement thereto) with the SEC or the dissemination thereof to the holders of the Company Common Stock, or responding to any comments of the SEC or its staff with respect to the Offer Documents, Parent and Merger Sub shall (A) provide the Company and its counsel a reasonable opportunity to review and comment on such Offer Documents or response (it being understood that the Company and its counsel shall provide any comments thereon as soon as reasonably practicable) and (B) give reasonable and good faith consideration to any comments made by the Company or its counsel. Parent and Merger Sub shall respond promptly to any comments of the SEC or its staff with respect to the Offer Documents. In addition, Parent and Merger Sub shall cause the Offer Documents (i) to comply in all material respects with the Exchange Act and other applicable laws and (ii) to not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that no covenant is made by Parent or Merger Sub with respect to information supplied by or on behalf of the Company for inclusion or incorporation by reference in the Offer Documents.

(c) Funding the Offer. Subject to Section 5.09, Parent shall be entitled to use or cause to be used some or all of the Closing Net Cash in order to pay (i) the Cash Amount with respect to each and any shares of the Company Common Stock that Merger Sub becomes obligated to purchase pursuant to the Offer and (ii) the Company Stock Option Cash Consideration and Restricted Stock Unit Cash Consideration payable in accordance with Section 3.10. Parent will notify the Company five (5) Business Days before the Merger Closing how much of the Closing Net Cash will be used to pay the foregoing.

14

(d) 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(d), on the tenth (10th) Business Day before each then 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 immediately prior to 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, access to the Company’s accountants and counsel at reasonable times and upon reasonable notice will be provided by 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.

(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 (5^th) calendar 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(d)(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(d)(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 the San Francisco office of Ernst & Young LLP, 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

15

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 for purposes of this Agreement. Parent shall cause Merger Sub to extend the expiration date of the Offer until the resolution of the matters described in this Section 2.01(d)(vi); provided, that Merger Sub 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(d)(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(d)(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.

(vii) The Cash Amount shall equal the quotient derived by dividing the (A) (1) the Closing Net Cash (as finally determined in accordance with Section 2.01(d)), minus $9,500,000; by (B) the Company Outstanding Shares. The Additional Price Per Share shall equal the Cash Amount as determined pursuant to the immediately preceding sentence, minus the Base Price Per Share.

SECTION 2.02 Company Actions.

(a) Schedule 14D-9. On the date the Offer Documents are filed with the SEC, or as promptly thereafter as practicable (but in no event later than the first (1st) Business Day following the date on which the Offer Documents are filed), the Company shall file with the SEC a Solicitation/Recommendation Statement on Schedule 14D-9 with respect to the Offer, (such Schedule 14D-9, as amended from time to time, together with any exhibits, amendments or supplements thereto, the “Schedule 14D-9”), including a description of the Special Committee Recommendation and the Company Board Recommendation (subject to Section 6.02) and shall disseminate the Schedule 14D-9 to the holders of the Company Common Stock, as and to the extent required by applicable U.S. federal securities Law.

The Company shall set the record date for the holders of Company Common Stock to receive such notice of appraisal rights as the same date as the Stockholder List Date and shall disseminate the Schedule 14D-9 including such notice of appraisal rights to such holders to the extent required by section 262(d) of the DGCL. Parent and Merger Sub shall furnish to the Company all information concerning Parent and Merger Sub required by applicable Law to be set forth in the Schedule 14D-9. Each of the Company, Parent and Merger Sub shall promptly correct any information provided by it for use in the Schedule 14D-9 if and to the extent that such information shall have become false or misleading in any material respect, and to correct any material omissions therefrom, and the Company shall take all steps necessary to amend or supplement the Schedule 14D-9 and to cause the Schedule 14D-9, as so amended or supplemented, to be filed with the SEC and disseminated to the holders of the Company Common Stock, in each case, as and to the extent required by applicable Law. Except from and after an Adverse Recommendation Change or in connection with any disclosures made in compliance with Section 6.02, Company shall provide Parent and its counsel with copies of any written comments, and shall inform Parent and its counsel of any oral

16

comments, that the Company or its counsel may receive from the SEC or its staff with respect to the Schedule 14D-9 promptly after the receipt of such comments. Except from and after an Adverse Recommendation Change or in connection with any disclosures made in compliance with Section 6.02, prior to the filing of the Schedule 14D-9 (including any amendment or supplement thereto) with the SEC or the dissemination thereof to the holders of the Company Common Stock, or responding to any comments of the SEC or its staff with respect to the Schedule 14D-9, the Company shall (x) provide Parent and its counsel a reasonable opportunity to review and comment on such Schedule 14D-9 or response (it being understood that Parent and its counsel shall provide any comments thereon as soon as reasonably practicable) and (y) give reasonable and good faith consideration to any comments made by Parent or its counsel. The Company shall respond promptly to any comments of the SEC or its staff with respect to the Schedule 14D-9. The Company hereby approves of and consents to the Offer, the Merger and the Transactions and the inclusion in the Offer Documents of a description of the Special Committee Recommendation and the Company Board Recommendation (except to the extent that the Special Committee or the Company Board shall have withdrawn or modified the Special Committee Recommendation or the Company Board Recommendation, respectively, in accordance with Section 6.02(b)). In addition, the Company shall cause the Schedule 14D-9 (i) to comply in all material respects with the Exchange Act and other applicable laws and (ii) to not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that no covenant is made by the Company with respect to information supplied by or on behalf of Parent or Merger Sub for inclusion or incorporation by reference in the Schedule 14D-9.

(b) Stockholder Information.

The date of the list of stockholders used to determine the persons to whom the Offer Documents and the Schedule 14D-9 are first disseminated is referred to as the “Stockholder List Date.” Subject to the requirements of applicable Law, and except for such steps as are necessary to disseminate the Offer Documents and any other documents necessary to consummate the Transactions, Parent and Merger Sub shall hold in confidence, in accordance with the Confidentiality Agreement, the information contained in any such labels, listings and files, shall use such information only in connection with the Offer and the Merger and, if this Agreement shall be terminated, shall, upon request, deliver to the Company or destroy (and shall direct their agents to deliver to the Company or destroy) all copies of such information (and certify in writing to the Company such destruction, if applicable).

(a) Capital Stock of Merger Sub. Each share of capital stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and become one fully paid and nonassessable share of common stock, par value $0.0001 per share, of the Surviving Corporation and shall constitute the only outstanding shares of capital stock of the Surviving Corporation.

(b) Cancelation of Treasury Stock and Certain Other Stock. Each share of Company Common Stock that (i) is owned by the Company immediately prior to the Effective Time, (ii) was owned by Parent, Merger Sub or any other subsidiary of Parent at the commencement of the Offer and is owned by Parent, Merger Sub or any other subsidiary of Parent immediately prior to the Effective Time or (iii) was irrevocably accepted for purchase in the Offer shall no longer be outstanding and, in each case, shall automatically be canceled and shall cease to exist, and no consideration shall be delivered or deliverable in exchange therefor.

(c) Conversion of Company Common Stock. Except as provided in Section 3.08(b) and Section 3.08(d), each share of the Company Common Stock issued and outstanding immediately prior to the Effective Time shall be converted into the right to receive the Offer Price without interest (the “Merger Consideration”), less any applicable tax withholding. 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), less any applicable tax withholding. 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.

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.

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

19

Agent”) for the payment of the Cash Amount pursuant to Section 3.08(c). The Surviving Corporation will deposit with the Paying Agent, at or promptly after the Effective Time, out of Closing Net Cash, cash necessary to pay the Cash Amount, if any, beyond what has been contributed by Parent, in respect of the shares of the Company Common Stock that were converted into the right to receive cash 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 registered, if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such payment shall pay any transfer or other Taxes required by reason of the payment to a Person other than the registered holder of such Certificate or establish to the satisfaction of Parent that such Tax has been paid or is not applicable. 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), less any applicable tax withholding, 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

20

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, less any applicable tax withholding.

(g) Termination of Payment Fund. Any portion of the Payment Fund (and any interest or other income earned thereon) that remains undistributed as of the 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 Parent. Nothing contained in this Section 3.09(i) and no investment losses resulting from the investment of the Payment Fund shall diminish the rights of the 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 Cash Amount of the Merger Consideration. Any interest and other income resulting from such investments shall be the property of, and paid to, Parent or its designated Affiliate.

(j) Withholding Rights. Each of the Company, the Surviving Corporation, Parent and the Paying Agent shall be entitled to deduct and withhold from the amounts otherwise payable pursuant to this Agreement or the Offer such amounts as are required to be deducted and withheld with respect to the making of such payment under the Code, or under any provision of state, local or foreign Tax Law. Amounts so deducted or withheld and timely paid over to the appropriate Tax Authority 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. Parent shall (i) use commercially reasonable efforts to provide advance notice of any such deduction or withholding and (ii) cooperate with the Company and any holders of Company Common Stock, Company Stock Options or Company Restricted Stock Units 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.

21

(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, less any applicable tax withholding, 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 Stock Option by (y) the number of shares of the Company Common Stock underlying such Company Stock Option (such amount, the “Company Stock Option Cash Consideration”) and (B) one CVR for each share of the Company Common Stock underlying such Company Stock Option. Parent shall cause the Surviving Corporation to pay the Company Stock 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 cancelled and the holder thereof shall be entitled to receive one CVR for each share of the Company Common Stock underlying such Company Stock Option; provided that each such CVR will provide for payment only after amounts otherwise payable under such CVR exceed a threshold equal to the excess of the exercise price per share of the Company Common Stock underlying such Company Stock Option over the Cash Amount.

(b) As of immediately prior to the Offer Closing Time, each Company Restricted Stock Unit that is then outstanding but not then vested shall become immediately vested in full. At the Effective Time, each Company Restricted Stock Unit that is then outstanding shall be canceled and the holder thereof shall be entitled to receive (i) an amount in cash without interest, less any applicable tax withholding, equal to the Cash Amount (the “Restricted Stock Unit Cash Consideration”) and (ii) one CVR. 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’s 2020 Employee Stock Purchase Plan (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 Stock Option or Company Restricted Stock Units shall have the right to acquire any equity interest in the Company or the Surviving Corporation in respect thereof and each Company Stock Plan shall terminate as of the Effective Time.

SECTION 3.11 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 Company Board and the Special Committee have taken all action necessary to render Section 203 of the DGCL and any other takeover, anti-takeover, moratorium, “fair price,” “control share,” or similar Law inapplicable to the Offer and the Merger. Assuming the accuracy of the representations and warranties set forth in Section 5.08, no restrictions of any other “business combination,” “control share acquisition,” “fair price,” “moratorium” or other anti-takeover Laws (each, a “Takeover Law”) apply or will apply to the Company pursuant to this Agreement or the Transactions.

SECTION 4.22 Opinion of Financial Advisor. The Company Board has received the opinion of Leerink Partners LLC, independent financial advisor to the Company Board, dated February 15, 2024, to the effect that, based upon and subject to the various assumptions, qualifications and limitations set forth therein, as of such date, the Cash Amount proposed to be paid to the holders of shares of Company Common Stock (other than (a) (i) shares of Company Common Stock owned by the Company immediately prior to the Effective Time, (ii) shares of Company Common Stock owned by Parent, Merger Sub or any other subsidiary of Parent at the commencement of the Offer which are owned by Parent, Merger Sub or any other subsidiary of Parent immediately prior to the Effective Time and (iii) solely with respect to the Merger, shares of Company Common Stock irrevocably accepted for purchase in the Offer, each of which shall automatically be canceled and shall cease to exist, and (b) Appraisal Shares) pursuant to the terms of this Agreement is fair, from a financial point of view, to such holders. It is agreed and understood that such opinion is for the benefit of the Company Board and may not be relied upon by Parent or Merger Sub. The Company will make available to Parent and Merger Sub a signed copy of such opinion as soon as possible following the Agreement Date.

SECTION 4.23 No Vote Required. Assuming the Transactions are consummated in accordance with Section 251(h) of the DGCL and assuming the accuracy of the representations and warranties set forth in Section 5.08, no stockholder votes or consents are needed to authorize this Agreement or for consummation of the Transactions.

REPRESENTATIONS AND WARRANTIES OF PARENT AND MERGER SUB

Except set forth in the letter, dated as of the Agreement Date, from the Parent and Merger Sub to the Company (which shall be arranged in numbered and lettered sections corresponding to the numbered and lettered sections contained in this Article V, and the disclosure in any section shall be deemed to qualify or apply to other sections in this Article V to the extent that it is reasonably apparent on its face that such disclosure also qualifies or applies to such other sections) (the “Parent Disclosure Letter”), Parent and Merger Sub, jointly and severally, represent and warrant to the Company that:

SECTION 5.01 Organization, Standing and Power. Each of Parent and Merger Sub is duly organized, validly existing and in good standing under the Laws of the jurisdiction in which it is organized (in the case of good standing, to the extent the concept is recognized by such jurisdiction) and has full corporate power and authority to conduct its businesses as presently conducted.

SECTION 5.02 Merger Sub.

(a) Merger Sub was formed solely for the purpose of entering into the Transactions, and since the date of its incorporation, Merger Sub has not carried on any business, conducted any operations or incurred any

The execution and delivery by each of Parent and Merger Sub of this Agreement and the consummation by it of the Transactions have been duly authorized by all necessary corporate action on the part of Parent and Merger Sub, subject, in the case of the Merger, to the adoption of this Agreement by Parent, as sole stockholder of Merger Sub (which shall occur immediately following the execution of this Agreement). Neither the approval and adoption of this Agreement nor the consummation of the Offer, the Merger or the other Transactions requires any approval of the stockholders of Parent. Each of Parent and Merger Sub has duly executed and delivered this Agreement, and, assuming due authorization, execution and delivery by the Company, this Agreement constitutes its, and at the Offer Closing Time the CVR Agreement will constitute Parent’s, legal, valid and binding obligation, enforceable against it in accordance with its terms (subject to the Bankruptcy, Equity and Indemnity Exception).

SECTION 5.04 No Conflicts; Consents.

(a) The execution and delivery by each of Parent and Merger Sub of this Agreement and the CVR Agreement do not, and the consummation of the Offer, the Merger and the other Transactions and compliance with the terms hereof will not, conflict with, or result in any violation of, or default (with or without notice or lapse of time, or both) under, any provision of (i) the organizational documents of Parent, Merger Sub or any of Parent’s subsidiaries, (ii) any Contract to which Parent or any of its subsidiaries is party or by which any of their respective properties or assets is bound or (iii) subject to the filings and other matters referred to in Section 5.04(b), any Judgment or Law applicable to Parent or any of its subsidiaries or their respective properties or assets, other than, in the case of clauses (ii) and (iii), any such items that would not reasonably be expected to, individually or in the aggregate, have a Parent Material Adverse Effect.

(b) No Consent of, or registration, declaration or filing with, or permit from, any Governmental Entity is required to be obtained or made by or with respect to Parent or any of its subsidiaries in connection with the execution, delivery and performance of this Agreement or the CVR Agreement or the consummation of the Transactions, other than (i) the filing with the SEC of (A) the Offer Documents and (B) such reports under the Exchange Act, as may be required in connection with this Agreement, the CVR Agreement, the Offer, the Merger and the other Transactions, (ii) the filing of the Certificate of Merger with the secretary of the State of Delaware, (iii) compliance with the rules and regulations of any national security exchange on which securities of Parent or the Company are listed and (iv) such other items that the failure of which to obtain or make would not reasonably be expected to, individually or in the aggregate, have a Parent Material Adverse Effect.

SECTION 5.05 Information Supplied. None of the information supplied or to be supplied by or on behalf of Parent or Merger Sub for inclusion or incorporation by reference in the Offer Documents or the Schedule 14D-9 will, at the time such document is filed with the SEC, at any time it is amended or supplemented or at the time it is first published, sent or given to the Company Stockholders, contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they are made, not misleading. The Offer Documents will comply as to form in all material respects with the requirements of the Exchange Act and the rules and regulations thereunder, except that no representation or warranty is made by Parent or Merger Sub with respect to statements included or incorporated by reference therein based on information supplied by or on behalf of the Company for inclusion or incorporation by reference therein.

38

SECTION 5.06 Brokers. No broker, investment banker, financial advisor or other Person is entitled to any broker’s, finder’s, financial advisor’s or other similar fee or commission in connection with the Offer, the Merger and the other Transactions based upon arrangements made by or on behalf of Parent or any of its Affiliates, directors, officers or employees.

SECTION 5.07 Litigation. There is no Proceeding pending or, to the knowledge of Parent, threatened against Parent or any subsidiary of Parent that would reasonably be expected to, individually or in the aggregate, have a Parent Material Adverse Effect, nor is there any Judgment outstanding against Parent or any subsidiary of Parent that would reasonably be expected to, individually or in the aggregate, have a Parent Material Adverse Effect.

SECTION 5.08 Ownership of the Company Common Stock. Neither Parent nor Merger Sub is, nor at any time for the past three years has been, an “interested stockholder” of the Company as defined in Section 203 of the DGCL. As of the date hereof, Parent or a subsidiary of Parent beneficially own no shares of the Company Common Stock and none of Parent or any subsidiary of Parent (i) owns (as such term is defined in Section 203 of the DGCL), directly or indirectly, any other shares of the Company Common Stock or other securities convertible into, exchangeable for, or exercisable for shares of the Company Common Stock or any securities of any subsidiary of the Company or (ii) has any rights to acquire any shares of the Company Common Stock except pursuant to this Agreement. Parent and each of its subsidiaries are affiliates of Merger Sub as such term is defined in section 251(h) of the DGCL.

SECTION 5.09 Sufficient Funds. Parent and Merger Sub have (or have available to them), and will have as of the Offer Closing Time and Effective Time sufficient cash available to pay all amounts to be paid by Parent and Merger Sub in connection with this agreement and the Merger Transactions, including Parent’s and Merger Sub’s costs and expenses and the aggregate Offer Price, Merger Consideration and Cash Amount on the terms and conditions contained in this agreement, and there is not, nor will there be, any restriction on the use of such cash or cash equivalents for such purpose. In no event shall the receipt or availability of any funds or financing by or to Parent, Merger Sub or any of their respective Affiliates or any other financing transaction be a condition to any of the obligations of Parent or Merger Sub hereunder.

SECTION 5.10 Competing Businesses. None of Parent or any of its Affiliates owns any controlling interest in any person that is developing products in the same markets in which Parent or Merger Sub operate that would reasonably be expected to have an adverse effect on the ability of Parent to consummate the Merger and the Transactions in a timely manner in accordance with the terms hereof.

SECTION 5.11 No Foreign Person. Neither Parent nor Merger Sub is a foreign person, as defined in 31 C.F.R. § 800.224. Each of Buyer and Merger Sub further represent that the transaction contemplated by this Agreement will not result in foreign control (as defined in 31 C.F.R. § 800.208) of the Company, and does not constitute direct or indirect investment in the Company by any foreign person that affords the foreign person with any of the access, rights, or involvement contemplated under 31 C.F.R. § 800.211(b).

(b) Neither the Company Board nor any committee thereof (including the Special Committee) shall (i) (A) withdraw, qualify or modify in a manner adverse to Parent or Merger Sub, or propose publicly to withdraw, qualify or modify in a manner adverse to Parent or Merger Sub, the Special Committee Recommendation or the Company Board Recommendation or resolve or agree to take any such action, (B) adopt, endorse, approve or recommend, or propose publicly to adopt, endorse, approve or recommend, any Company

Notwithstanding anything to contrary in the foregoing or any other provision of this Agreement, (x) the Company Board (acting upon the recommendation of the Special Committee) or the Special Committee may, in response to an Intervening Event, take any of the actions specified in clause (A) or (D) of the definition of Adverse Recommendation Change (an “Intervening Event Adverse Recommendation Change”) if the Company Board (acting upon the recommendation of the Special Committee) or the Special Committee determines, in good faith, after consultation with outside counsel, that the failure to take such action would be inconsistent with its fiduciary duties under applicable Law and (y) if the Special Committee or the Company Board receives a Superior Company Proposal that did not result from a material breach of this Section 6.02, the Company may make an Adverse Recommendation Change, and may terminate this Agreement pursuant to Section 9.01(h) in order to enter into a definitive agreement with respect to the Superior Company Proposal; provided that, prior to so making an Intervening Event Adverse Recommendation Change or an Adverse Recommendation Change, or so terminating this Agreement pursuant to Section 9.01(h), (1) the Company Board (acting upon the recommendation of the Special Committee) or the Special Committee 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 Company Notice, in respect of a Superior Company Proposal, shall specify the identity of the Person who made such Superior Company Proposal and subject to any restrictions pursuant to any confidentiality agreement in effect, the material terms and conditions of such Superior Company Proposal and attach the most current version of the relevant transaction agreement or, in respect of an Intervening Event, shall include a reasonably detailed description of the underlying facts giving rise to such action), (2) the Company shall have negotiated, and shall have 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 such a manner that would eliminate the need for taking such action (and, in respect of a Superior Company Proposal, would cause such Superior Company Proposal to no longer constitute a Superior Company Proposal), (3) following the end of such notice period, the Company Board (acting upon the recommendation of the Special Committee) or the Special Committee shall have considered in good faith any revisions to this Agreement irrevocably committed to in writing by Parent, and shall have determined in good faith, after consultation with outside counsel, that failure to effect such Adverse Recommendation Change or Intervening Event Adverse Recommendation Change would be inconsistent with its fiduciary duties under applicable Law and, with respect to a Superior Company Proposal, that such Superior Company Proposal continues to constitute a Superior Company Proposal and (4) in the event of any change to any of the financial terms (including the form and amount of consideration) of such Superior Company Proposal, or in the event of any material change in any event, occurrence or facts relating to such Intervening Event, the Company shall, in each case, deliver to Parent an additional Company Notice consistent with that described in clause (1) of this proviso and a renewed notice period under clause (1) of this proviso shall commence (except that the four (4)-Business Day notice period referred to in clause (1) 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(b) anew with respect to such additional Company Notice, including clauses (1) through (4) of this proviso.

(c) Nothing contained in this Section 6.02 or elsewhere in this Agreement shall prohibit the Company from (i) taking and disclosing to its stockholders a position contemplated by Rule 14d-9 or Rule 14e-2(a) promulgated under the Exchange Act (or any similar communication to stockholders), including making any

43

“stop, look and listen” communication to the stockholders of the Company or (ii) making any disclosure to its stockholders if the Company Board (acting upon the recommendation of the Special Committee) or the Special Committee determines, in good faith, after consultation with outside counsel, that the failure to take such action would be inconsistent with its fiduciary duties or applicable Law; provided that any such action that would otherwise constitute an Adverse Recommendation Change shall be made only in compliance with Section 6.02(b) (it being understood that: (A) any “stop, look and listen” letter or similar communication limited to the information described in Rule 14d-9(f) under the Exchange Act and (B) any disclosure of information to the Company Stockholders that describes the Company’s receipt of a Company Takeover Proposal and the operation of this Agreement with respect thereto and contains a statement that the Special Committee or the Company Board, as applicable, has not effected an Adverse Recommendation Change shall be deemed to not be an Adverse Recommendation Change).

(d) 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 paragraphs (a) and (b) of this Section 6.02, 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 request for information or inquiry, proposal or offer that the Company Board (acting upon the recommendation of the Special Committee) or the Special Committee 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 amendments or modifications thereto) and the identity of the Person making any such Company Takeover Proposal or inquiry, proposal or offer. Commencing upon the provision of any notice referred to in the previous sentence, the Company and its Representatives shall keep Parent informed on a reasonably prompt basis as to any material developments with respect to any such Company Takeover Proposal or inquiry, proposal or offer (and any subsequent material amendments or modifications thereto), and shall provide Parent with a copy of any written correspondence, documents or agreements delivered to or by the Company or its Representatives that contain any material amendments thereto or any material change to the scope or material terms or conditions thereof (or, if not delivered in writing, a summary of any such material amendments or material changes).

(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, 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 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

45

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, the Surviving Corporation shall indemnify and hold harmless, as and to the fullest extent permitted by applicable Law, each such Indemnified Party against any losses, claims, damages, liabilities, costs, expenses (including reasonable attorney’s fees and expenses in advance of the final disposition of any Proceeding to each Indemnified Party to the fullest extent permitted by applicable Law upon receipt of any undertaking required by applicable Law), judgments, fines and amounts paid in settlement of or in connection with any such threatened or actual Proceeding. The Surviving Corporation shall cooperate with an Indemnified Party in the defense of any matter for which such Indemnified Party could seek indemnification hereunder; provided, that Parent and the Surviving Corporation shall be entitled to assume the defense and appoint lead counsel for such defense, except to the extent otherwise provided in an indemnification agreement set forth in the Company Disclosure Letter. The Surviving Corporation shall not settle, compromise or consent to the entry of any judgment in any threatened or actual Proceeding for which indemnification could be sought by an Indemnified Party hereunder, unless such settlement, compromise or consent includes an unconditional release of such Indemnified Party from all liability arising out of such Proceeding or such Indemnified Party otherwise consents in advance in writing to such settlement, compromise or consent. The Surviving Corporation’s obligations under this Section 7.03(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. Parent shall cause the Surviving Corporation to perform its obligations under this Section 7.03(b).

(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.

(d) In the event that (i) the Surviving Corporation or any of its successors or assigns (A) consolidates with or merges into any other Person and is not the continuing or surviving corporation or entity of such consolidation or merger or (B) transfers or conveys all or a substantial portion of its properties or other assets to any Person or (ii) Parent or any of its successors or assigns dissolves the Surviving Corporation, then, and in each

46

such case, Parent shall cause proper provision to be made so that the applicable successors and assigns or transferees expressly assume the obligations set forth in this Section 7.03.

(e) From and after the Offer Closing Time, the obligations of Parent and the Surviving Corporation under this Section 7.03 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 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.

(f) Parent shall pay all reasonable and documented expenses, including reasonable attorneys’ fees, that may be incurred by any Indemnified Party in successfully enforcing the indemnity and other obligations provided in this Section 7.03.

SECTION 7.04 Fees and Expenses. Except as set forth in Section 7.03, Section 7.06 and Section 9.03, all fees and expenses incurred in connection with this Agreement, the Offer, the Merger and the other Transactions shall be paid by the party incurring such fees or expenses, whether or not the Offer or the Merger is consummated.

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(d).

SECTION 7.06 Transfer Taxes. Except as provided in Section 3.09(b), all stock transfer, real estate transfer, documentary, stamp, recording and other similar Taxes (including interest, penalties and additions to any such Taxes) (“Transfer Taxes”) imposed on the Transactions shall be paid by Parent or Merger Sub when due, and the Company shall cooperate with Merger Sub and Parent in preparing, executing and filing any Tax Returns with respect to such Transfer Taxes.

SECTION 7.07 Stockholder Litigation. During the Pre-Closing Period, the Company shall provide Parent an opportunity to review and to propose comments to all material filings or responses to be made by the Company in connection with any 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 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.

47

SECTION 7.08 Rule 14d-10 Matters. Prior to the scheduled expiration of the Offer, the Company (acting through the Company Board and the compensation committee of the Company Board) shall use reasonable best efforts to cause to be exempt under Rule 14d-10(d) promulgated under the Exchange Act any employment compensation, severance or other employee benefit arrangement that has been, or after the Agreement Date will be, entered into by the Company with current or future directors, officers or employees of the Company.

SECTION 7.09 Rule 16b-3 Matters.

SECTION 7.12 No Control of Other Party’s Business. Nothing contained in this Agreement is intended to give Parent or Merger Sub, directly or indirectly, the right to control or direct the Company’s operations prior to the Effective Time. Prior to the Effective Time, the Company shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its operations, subject to the provisions in Section 6.01.

SECTION 7.13 Anti-Takeover Provisions. Each of Parent and the Company and the Company Board (and any committee empowered to take such action, if applicable) will (i) take all actions within their power to ensure that no Takeover Law is or becomes applicable to this Agreement, the Offer, Offer Documents, the Merger or any of the transactions contemplated by this Agreement; and (ii) if any Takeover Law becomes applicable to this Agreement, the Offer, Offer Documents, the Merger or any of the transactions contemplated by this Agreement, take all action within their power to ensure that the Merger and the other transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such statute or regulation on the Offer, the Merger and the other transactions contemplated by this Agreement.

SECTION 7.16 Permitted Dispositions.

48

obligations or liabilities on the Company or any of its subsidiaries, the terms of the Permitted Disposition relating to such obligations or liabilities shall be reasonably acceptable to Parent, it being acknowledged that any such Permitted Disposition that is (i) made pursuant to an asset purchase agreement in substantially the form referenced in Section 7.16 of the Company Disclosure Schedule (the “Form Asset Purchase Agreement”) or (ii) that does not impose any obligations or liabilities on the Company or its subsidiaries beyond those contained in the Form Asset Purchase Agreement, shall be deemed reasonably acceptable to Parent. The parties hereto acknowledge that the Company may not be successful in completing, or may determine not to proceed, with any Permitted Dispositions.

SECTION 7.17 Employee Matters.

(a) If, at least ten (10) Business Days prior to the Effective Time, Parent provides written notice to the Company directing the Company to terminate its 401(k) plan(s), the Company shall terminate any and all 401(k) plans effective as of the day immediately preceding the day on which the Effective Time occurs (the “401(k) Termination Date”).

(c) The provisions of this Section 7.17 are for the sole benefit of Parent and the Company and no provision of this Agreement shall (i) create any third-party beneficiary or other rights in any Person other than Parent and Company, including rights in respect of any benefits that may be provided, directly or indirectly, under any Company Benefit Plan or any employee benefit plan of Parent or any Affiliate, or rights to continued employment or service with the Company or Parent (or any Affiliate thereof), (ii) be construed as an amendment, waiver or creation of any Company Benefit Plan, or any employee benefit plan of Parent or any Affiliate, (iii), subject to the requirements explicitly set forth in this Section 7.17, serve as a limitation on the ability of the Company, Parent or applicable Affiliate to amend, waive, create, suspend or terminate any Company Benefit Plan, or any employee benefit plan of Parent or any Affiliate, or (iii) limit the ability of the Company, Parent or applicable Affiliate to terminate the employment of any employee.

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.

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

51

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

(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 (x) in the case of this Agreement being subsequently terminated pursuant to Section 9.01(b)(i), prior to the date that is four (4) Business Days prior to the final expiration date of the Offer or (y) in the case of this Agreement being subsequently terminated pursuant to Section 9.01(c) as a result of a breach by the Company of a covenant in this Agreement, prior to the time of the breach giving rise to such termination, (B) this Agreement is terminated by (x) either Parent or the Company pursuant to Section 9.01(b)(i) (but in the case of a termination by the Company, only if at such time Parent would not be prohibited from terminating this Agreement pursuant to the proviso in Section 9.01(b)(i)) or (y) Parent pursuant to Section 9.01(c) as a result of a breach by the Company of a covenant in this Agreement, and (C) within 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.

(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 $1,250,000 (the “Expense Reimbursement Payment”) if Parent terminates this Agreement pursuant to Section 9.01(e).

(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). 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 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 costs and expenses (including reasonable 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 of Citibank, N.A. in effect from time to time from the date such payment was required to be made hereunder through the date such payment was actually received.

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

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

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 Special Committee or the duly authorized designee of the Special Committee.

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 10.05 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

54

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-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 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.

55

SECTION 10.08 Specific Enforcement; Jurisdiction.

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

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

56

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 Special Committee Matters. For all purposes of this Agreement, the Company (prior to the Effective Time) and the Company Board, as applicable, shall act, including with respect to the granting of any consent, permission, approval, amendment or waiver or the making of any determination, only as directed by the Special Committee or its designees. Prior to the Effective Time, without the consent of the Special Committee, the Company Board shall not (a) eliminate, revoke or diminish the authority of the Special Committee or (b) remove or cause the removal of any director of the Company Board that is a member of the Special Committee from the Company Board or the Special Committee. The Special Committee (and, for so long as the Special Committee is in existence, only the Special Committee) may pursue any action or litigation with respect to breaches of this Agreement on behalf of the Company.

SECTION 10.13 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 10.13.

ARTICLE II

CONTINGENT VALUE RIGHTS

Section 2.1 CVRs. The CVRs represent the contractual rights of Holders to receive contingent cash payment of the aggregate CVR Proceeds from Purchaser pursuant to this Agreement.

Section 2.2 Nontransferable. The CVRs may not be sold, assigned, transferred, pledged, encumbered or in any other manner transferred or disposed of, in whole or in part, other than through a Permitted CVR Transfer. Any attempted sale, assignment, transfer, pledge, encumbrance or disposition of CVRs, in whole or in part, in violation of this Section 2.2 shall be void ab initio and of no effect.

C-6

Section 2.3 No Certificate; Registration; Registration of Transfer; Change of Address.

(a) The CVRs will be issued and distributed by Purchaser to each Holder in book-entry form only and will not be evidenced by a certificate or other instrument.

(b) The Rights Agent will keep a register (the “CVR Register”) for the purpose of (i) identifying the Holders of CVRs and (ii) registering CVRs and Permitted CVR Transfers thereof. The CVR Register will initially show one position for Cede & Co. representing all the Company Common Stock held by DTC on behalf of the street holders of the Company Common Stock held by such Holders as of immediately prior to the Effective Time. The Rights Agent will have no responsibility whatsoever directly to the street name holders with respect to transfers of CVRs unless and until such CVRs are transferred into the name of such street name holders in accordance with Section 2.2. 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 request of a Holder or the Representative, the Rights Agent will make available to such Holder or the Representative, as applicable, a list of the other Holders, the number of CVRs held by each Holder, the contact information 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.

(c) Subject to the restrictions on transferability set forth in Section 2.2, 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, 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, Parent and 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 Purchaser 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 Holder’s address of record in the CVR Register. The written request must be duly executed by the Holder. Upon receipt of such written notice, the Rights Agent will promptly record the change of address in the CVR Register.

Section 2.4 Payment Procedures: Notices.

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

(b) On or prior to each CVR Payment Date, with respect to any Disposition Agreement or Permitted Disposition, Parent 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 Disposition Proceeds,

C-7

(B) in the case of Disposition Proceeds, the source and trigger event for such payment of Disposition Proceeds, (C) a detailed calculation of Gross Proceeds (including any calculations and/or supporting documentation applicable to any allocation determination for consideration related or not related to a CVR Product), Net Proceeds and any Permitted Deductions used to calculate such Disposition Proceeds with reasonable supporting detail for such Permitted Deductions, as applicable, (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, Parent shall deliver to the Rights Agent the CVR Payment Amounts required by Section 4.2. All amounts delivered by Parent hereunder shall be delivered in U.S. dollars. For the avoidance of doubt, Parent 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 Parent’s obligations set forth in this Section 2.4(b) and Section 2.5.

(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 and, following the applicable CVR Payment Date, promptly pay the CVR Payment Amount to each of the Holders 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.

(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 Parent or Purchaser, upon demand, and any Holder will thereafter look only to Parent and Purchaser for payment of the CVR Payment Amount, without interest, but such Holder will have no greater rights against Parent and Purchaser than those accorded to general unsecured creditors of Parent and Purchaser under applicable Law.

(e) None of Parent, any of its Affiliates (including Purchaser), 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 Parent’s, any of its Affiliates’ and/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 Parent or Purchaser, 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, Parent and Purchaser agree to indemnify and hold harmless Rights Agent with respect to any liability, penalty, cost or expense Rights Agent may incur or be subject to in connection with transferring such property to Parent or Purchaser.

Section 2.5 Tax Matters.

(a) Except to the extent any portion of the CVR Payment Amount is required to be treated as imputed interest pursuant to applicable Law, the parties 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, (ii) any CVR Payment Amount received in respect of such CVRs will be treated as an amount realized on the disposition or partial disposition of the applicable CVRs, and (iii) 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 parties to this Agreement shall file all U.S. federal, state and local Tax Returns in a manner consistent with clauses (i) and (ii), unless otherwise required by applicable Laws and clause (iii), unless otherwise required by a “determination” within the meaning of Section 1313(a) of the Code (or a similar determination under applicable state or local Law).

C-8

(b) In addition to any Permitted Deductions, Parent and its Affiliates (including Purchaser) and the Rights Agent shall be entitled 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 Parent through the payroll system or any successor payroll system of Parent or any of its Affiliates, including the Company. Prior to making (or causing to be made) any such Tax deduction or withholding, Parent shall instruct the Rights Agent to provide the opportunity for the Holders to provide duly executed Internal Revenue Service Forms W-9 or 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 promptly and timely remit, or cause to be remitted, any amounts withheld in respect of Taxes to the appropriate Governmental Body. To the extent any amounts are so deducted and withheld, 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.

(c) Parent, Purchaser 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, Parent, Purchaser 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 Parent, the Company or the 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 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. Parent 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.

Section 2.6 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 and/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 to act as the exclusive representative, agent and attorney-in-fact of such Holder and all Holders as set forth in this Agreement, which shall include the power and authority of the Representative to take or refrain from taking the actions specified herein and any other actions relating to the subject matter of this Agreement as determined by the Representative. Each Holder agrees that such Holder will not challenge or contest any action, inaction, determination or decision of the Representative or the authority or power of the Representative and will not

C-9

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.

(d) Parent, its Board 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 Disposition will occur during the Disposition Period and that there will not be any Gross Proceeds that may be the subject of a CVR Payment Amount.

Section 2.7 Ability to Renounce or Abandon CVR. Notwithstanding anything to the contrary contained herein, any Holder or Holder’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 Purchaser or Parent without consideration therefor, effected by written notice to the Rights Agent, the Representative and Parent, which renouncement and abandonment notice, if given, shall be irrevocable. Nothing in this Agreement shall prohibit Parent or any of its Affiliates (including Purchaser) 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 Parent or any of its Affiliates (including Purchaser) 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.

The Representative will incur no liability of any kind to the Holders with respect to any action or omission by the Representative in connection with the Representative’s services in connection with this Agreement, except in the event of liability directly resulting from the Representative’s bad faith, gross negligence, fraud or willful misconduct.

Form of Tender and Support Agreement

SUPPORT AGREEMENT

This SUPPORT AGREEMENT (“Agreement”), dated as of February 16, 2024, is made by and among XOMA Corporation, a Delaware corporation (“Parent”), XRA 1 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 Kinnate Biopharma 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 February 16, 2024, 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 Merger Sub to commence a tender offer for all of the issued and outstanding shares of Company Common Stock (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”);

WHEREAS, the board of directors of the Company (the “Board”) has, prior to the execution and delivery of this Agreement, taken all actions so that the restrictions applicable to business combinations contained in Section 203 of the DGCL and any other Takeover Law are, and will be, inapplicable to the execution, delivery and performance of this Agreement and the transactions contemplated hereby (the “203 Approval”); and

WHEREAS, as an inducement and a condition to the willingness of Parent and Merger Sub to enter into the Merger Agreement, and in consideration of the substantial expenses incurred and to be incurred by them in connection therewith, the Stockholder has agreed to enter into and perform this Agreement.

NOW, THEREFORE, in consideration of, and as a condition to, Parent and Merger 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 Parent in connection therewith, the parties hereto agree as follows:

1. Agreement to Tender Shares.

(a) Subject to the terms of this Agreement and the 203 Approval (which has been obtained prior to the execution 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 Merger Sub or Parent pursuant to the Offer or pursuant to the Merger Agreement, shall be transferred to Merger Sub and Parent upon the transfer to Merger Sub or Parent of Stockholder’s Shares.

D-1

(c) If the Board or the Special Committee has effected (and not withdrawn) an Intervening Event Adverse Recommendation Change in accordance with the Merger Agreement, then the obligation of Stockholder to tender its Shares in the manner set forth in this Section 1 shall be, by virtue of such Intervening Event Adverse Recommendation Change, automatically modified such that the Stockholder, together with the other stockholders of the Company entering into substantially similar tender and support agreements with Parent and Merger Sub on the date hereof (the “Other Support Agreements”), shall collectively only be required to tender into the Offer that number of Shares equal to an aggregate number of Shares which, together with Shares as defined in the Other Support Agreements, equal in the aggregate thirty percent (30%) of the total number of shares of Company Common Stock outstanding as of the expiration of the Offer (with Stockholder being obligated to tender its pro rata portion thereof).

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, (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 stockholders of the Company pursuant to the terms of the Merger Agreement, (d) the mutual written agreement of the parties to terminate this Agreement, (e) any material breach of this Agreement or the Merger Agreement by Parent or Merger Sub or (f) the Board or the Special Committee approves, recommends, encourages or supports an alternative transaction. 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. The Stockholder agrees that any Shares of the Company (and any securities convertible into or exercisable or exchangeable or redeemable for Shares) that the Stockholder purchases or with respect to which the 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.

(a) From and after the date hereof until the Termination Date, except as otherwise provided herein (including pursuant to Section 1 or Section 7) or in the Merger Agreement, Stockholder shall not, and Stockholder shall not direct its Affiliates to: (i) voluntarily transfer, assign, sell, gift-over, hedge, pledge or otherwise dispose (whether by sale or merger, liquidation, dissolution, dividend or distribution, by operation of Law or otherwise) of, enter into any derivative arrangement with respect to, create or suffer to exist any Liens (except for Permitted Liens) on or consent to any of the foregoing (“Transfer”), any or all of the Shares or any right or interest therein; (ii) enter into any contract, option or other agreement, arrangement or understanding with respect to any Transfer; (iii) grant or permit the grant of any proxy, power-of-attorney or other authorization or consent with respect to any of the Shares with respect to any matter that is, or that is reasonably likely to be exercised in a manner, inconsistent with the transactions contemplated by the Merger Agreement or the provisions thereof; (iv) deposit any of the Shares into a voting trust, or enter into a voting agreement or arrangement with respect to any of the Shares; or (v) directly take or cause the taking of any other action that would restrict, limit or interfere with the performance of Stockholder’s obligations hereunder or the transactions contemplated hereby, except, in each case, as would not reasonably be expected to have, individually or in the aggregate, a material adverse effect on such Stockholder’s ability to timely perform its obligations under this Agreement; provided, that Stockholder and its Affiliates shall be permitted to Transfer Shares to Affiliates, so long as such transferees agree to remain subject to the terms of this Agreement. Without limiting the foregoing,

D-2

at all times commencing with the execution and delivery of this Agreement and continuing until Termination Date, Stockholder shall not tender the Shares into any tender or exchange offer commenced by a Person other than Parent, Merger Sub or any other subsidiary of Parent.

(b) The Stockholder hereby agrees not to commence or knowingly participate in any Proceeding, derivative or otherwise, against Parent, Merger Sub, the Company or any of their respective successors or their Affiliates and each of their successors and assigns and their respective directors and officers (i) challenging the validity of, or seeking to enjoin or delay the operation of, any provision of this Agreement or the Merger Agreement (including any claim seeking to enjoin or delay the Offer Closing Time or the Merger Closing) or (ii) alleging a breach of any duty of the Board in connection with the Merger Agreement, this Agreement or the transactions contemplated thereby or hereby.

5. Representations and Warranties of the Stockholder. The Stockholder hereby represents and warrants, as of the date hereof, to Parent and Merger Sub as follows:

(b) Stockholder has the full power and authority to execute and deliver this Agreement and to perform Stockholder’s obligations hereunder, subject to applicable federal securities laws and the terms of this Agreement; if the Stockholder is not an individual, it is duly organized, validly existing and in good standing under the laws of its jurisdiction of organization and has taken all action necessary, to execute, deliver and perform its obligations under this Agreement and to consummate the transactions contemplated hereby, and no other proceedings on the part of the Stockholder are necessary to authorize this Agreement, the performance of Stockholder’s obligations hereunder and the consummation of the transactions contemplated hereby.

(c) This Agreement (assuming this Agreement constitutes a valid and binding agreement of Parent and Merger Sub) has been duly executed and delivered by or on behalf of the Stockholder and constitutes a valid and binding agreement with respect to the Stockholder, enforceable against the Stockholder in accordance with its terms, subject to (i) laws of general application relating to bankruptcy, insolvency and the relief of debtors, and (ii) rules of law governing specific performance, injunctive relief and other equitable remedies.

(d) The shares of Company Common Stock and the certificates, if any, representing the Shares owned by Stockholder are now held by Stockholder, by a nominee or custodian for the benefit of Stockholder or by the depository under the Offer, free and clear of any liens, claims, charges, proxies, powers of attorney, rights of first offer or rights of first refusal, voting agreement or voting trust or any other agreement, arrangement, or restriction with respect to the voting of such Shares, or other encumbrances or restrictions of any kind whatsoever (“Liens”), and has sole or shared, and otherwise unrestricted, voting power with respect to such Shares, except for (i) any such Liens arising hereunder (in connection therewith any restrictions on transfer or any other Liens have been waived by appropriate consent) and (ii) Liens imposed by federal or state securities laws (collectively, “Permitted Liens”).

(e) Neither the execution and delivery of this Agreement by such Stockholder nor the consummation of the transactions contemplated hereby nor compliance by such Stockholder with any provisions herein will (i) if such Stockholder is not an individual, violate, contravene or conflict with or result in any breach of any provision of the certificate of incorporation or bylaws (or other similar governing documents) of such Stockholder, (ii) violate, conflict with, or result in a breach of any provisions of, or require any consent, waiver or approval or result in a default or loss of a benefit (or give rise to any right of termination, cancellation, modification or acceleration or any event that, with the giving of notice, the passage of time or otherwise, would constitute a

D-3

default or give rise to any such right) under any of the terms, conditions or provisions of any Contract or other legally binding instrument or obligation to which such Stockholder is a party or by which such Stockholder or any of its assets may be bound, (iii) result (or, with the giving of notice, the passage of time or otherwise, would result) in the creation or imposition of any Lien on any assets (including Shares) of such Stockholder (other than one created by Parent or Merger Sub) or (iv) violate any Law applicable to such Stockholder or by which any of its assets (including Shares) are bound, except, in each case, as would not reasonably be expected to have, individually or in the aggregate, a material adverse effect on such Stockholder’s ability to timely perform its obligations under this Agreement.

(f) Stockholder has not directly engaged any broker, investment banker, financial advisor, finder, agent or other Person such that such Person is entitled to any broker’s, finder’s, financial adviser’s or other similar fee or commission in connection with this Agreement.

(g) The Stockholder understands and acknowledges that Parent and Merger Sub are entering into the Merger Agreement in reliance upon the Stockholder’s execution and delivery of this Agreement.

6. Representations and Warranties of Parent and Merger Sub. Each of Parent and Merger Sub hereby represents and warrants to Stockholder as follows:

24. Specific Performance.

Any requirements for the securing or posting of any bond with respect to any such remedy are hereby waived. The parties hereto further agree that by seeking the remedies provided for in this Section 24, a party shall not in any respect waive its right to seek any other form of relief that may be available to such party under this Agreement (including monetary damages) for breach of any of the provisions of this Agreement or in the event that the remedies provided for in this Section 24 are not available or otherwise are not granted.
