Each suchIn-the-Money Assumed Option shall continue to have, and shall be subject to, the same terms and conditions (including the applicable time-vesting and/or performance-vesting conditions and any provisions for accelerated vesting) as applied to the correspondingIn-the-Money Option immediately prior to the Effective Time.In addition to anIn-the-Money Assumed Option, each holder of anIn-the-Money Option outstanding and unexercised immediately before the Effective Time shall, as of the Effective Time, also receive either (A) with respect to anIn-the-Money Option that is vested immediately prior to the Effective Time (each, a “VestedIn-the-Money Option”), one fully vested CVR for each share of Company Common Stock underlying such vestedIn-the Money Option that will be payable under the terms, including timing of payment, of the applicable CVR Agreement (each, a “Vested CVR”) or (B) with respect to anyIn-the-Money Option that is not vested immediately prior to the Effective Time (each, an “UnvestedIn-the-Money Option”), an unvested CVR for each share of Company Common Stock underlying such UnvestedIn-the-Money Option that will be subject to vesting upon the same time-vesting schedule that applied to the correspondingIn-the-Money Option that will be payable under the terms, including timing of payment, of the applicable CVR Agreement(each, an “Unvested CVR”), provided that if the holder of such Unvested CVR is employed or in the service of Parent, the Surviving Corporation or one of their Subsidiaries on the date a payment is due under the applicable CVR Agreement, then such Unvested CVR will be deemed vested on such date with respect to such payment. In the event that the employment or other service with Parent, the Surviving Corporation or one of their Subsidiaries of a holder of an Unvested CVR is terminated for any reason prior to the vesting of the Unvested CVR for any reason that would trigger the forfeiture of the corresponding UnvestedIn-the-Money Option, such Unvested CVR will be forfeited without payment.

(b) EachOut-of-the-Money Option outstanding and unexercised immediately before the Effective Time shall, as of the Effective Time, automatically and without any action on the part of the holder thereof, be assumed by Parent and converted into a Parent Stock Option to purchase (a) that number of shares of Parent Common Stock (rounded down to the nearest whole share) equal to the product obtained by multiplying (i) the total number of shares of Company Common Stock subject to suchOut-of-the-Money Option immediately prior to the Effective Time by (ii) theOut-of-the-Money Exchange Ratio, (b) at aper-share exercise price (rounded up to the nearest whole cent) equal to the quotient obtained by dividing (i) the exercise price per share of Company Common Stock at which such Company Stock Option was exercisable immediately prior to the Effective Time by (ii) theOut-of-the- Money Exchange Ratio (each, an “Out-of-the-Money Assumed Option”). Each suchOut-of-the-Money Assumed Option shall continue to have, and shall be subject to, the same terms and conditions (including the applicable time-vesting and/or performance-vesting conditions and any provisions for accelerated vesting) as applied to the correspondingOut-of-the Money Option immediately prior to the Effective Time.

(c) Prior to the Effective Time, the Board of Directors of the Company (or, if appropriate, any committee thereof administering the Company Stock Plan) and the Board of Directors of Parent (or if appropriate, any committee thereof administering the Parent Stock Plan) shall each pass resolutions to effect the foregoing provisions of thisSection 2.7.

Section 2.8Appraisal Rights. Notwithstanding anything in this Agreement to the contrary, if required by the DGCL (but only to the extent required thereby) any shares of Company Common Stock that are issued and outstanding immediately prior to the Effective Time and that are held by holders who have not voted such shares of Company Common Stock in favor of the adoption of this Agreement and who are entitled to and have properly demanded appraisal rights with respect thereto in accordance with Section 262 of the DGCL, have complied in all respects with Section 262 of the DGCL and have not effectively withdrawn such demand (collectively, “Dissenting Shares”) shall not be converted into the right to receive the Merger Consideration as provided inSection 2.6(b), unless and until such Person shall have effectively withdrawn or otherwise lost or failed to perfect such Person’s right to appraisal or payment under the DGCL, at which time (a) such shares of Company Common Stock shall be treated as if they had been converted into and become exchangeable for the right to receive, as of the Effective Time, the Merger Consideration as provided inSection 2.6(b), without interest and after giving effect to any required Tax withholdings pursuant toSection 3.3, (b) such shares of Company Common Stock shall not be deemed Dissenting Shares and (c) such holder thereof shall cease to have any other rights with respect to such shares of Company Common Stock. Each Dissenting Share shall no longer be outstanding, shall automatically be canceled and extinguished and shall cease to exist at the Effective Time, and each holder of Dissenting Shares shall be entitled to receive only the payment of the fair value of such Dissenting Shares in accordance with the provisions of, and as provided by, Section 262 of the DGCL with respect to such Dissenting Shares unless and until such Person shall have effectively withdrawn or otherwise lost or failed to perfect such Person’s right to appraisal or payment under the DGCL. The Company shall give Parent prompt written notice of any written demands for appraisal or withdrawals of such demands, and any other instruments served pursuant to applicable Law that are received by the Company relating to stockholders’ rights of appraisal. The Company shall not, except with the prior written consent of Parent, and prior to the Effective Time, Parent shall not, except with the prior written consent of the Company, make any payment with respect to any demands for appraisal or offer to settle or compromise, or settle or compromise or otherwise negotiate, any such demands, or approve any withdrawal of any such demands, or waive any failure to timely deliver a written demand for appraisal or otherwise to comply with the provisions under Section 262 of the DGCL, or agree to do any of the foregoing.

Section 2.9Parent Board. The Board of Directors of Parent shall appoint Dr. Gerard Ber and Mr. Heinz Mausli (the “Company Directors”) to serve, effective as of the Effective Time, on the Board of Directors of Parent. In addition, the Board of Directors of Parent shall take such actions as are necessary so that there are a total of nine members of the Board of Directors of Parent as of the Effective Time, after giving effect to the appointments of the Company Directors.

ARTICLE III

EXCHANGE OF SHARES

Section 3.1Surrenderand Payment.

(a) Prior to the Effective Time, Parent shall appoint an exchange agent reasonably acceptable to the Company (the “Exchange Agent”) for the purpose of exchanging shares of Company Common Stock for the Stock Consideration payable in respect thereof. As soon as reasonably practicable after the Effective Time, Parent will send, or will cause the Exchange Agent to send, to each holder of record of one or more Certificates as of the Effective Time, whose shares of Company Common Stock were converted into the right to receive the Stock Consideration pursuant toSection 2.6 (Effect on Capital Stock), 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 Exchange Agent) in such form as Parent may specify subject to the Company’s reasonable approval prior to the Effective Time, including instructions for use in effecting the surrender of Certificates (or effective affidavits of loss in lieu thereof) to the Exchange Agent in exchange for the Stock Consideration. At the Effective Time, Parent shall cause to be deposited with the Exchange Agent, for the benefit of the holders of shares of Company Common Stock, shares of Parent Common Stock (which shall be innon-certificated book-entry form) to be issued pursuant toSection 2.6 (Effect on Capital Stock) and an amount of cash in U.S. dollars sufficient to be paid pursuant toSection 3.5 (No Fractional Shares), payable to holders of the Book-Entry Shares or payable to the holders of Certificates upon due surrender of the Certificates (or effective affidavits of loss in lieu thereof), in each case, pursuant to the provisions ofArticle II and thisArticle III (it being understood and agreed, for the avoidance of doubt, that Parent shall not be required to deposit any funds related to any CVR with the Rights Agent unless and until such deposit is required pursuant to the terms of the CVR Agreement). With respect to any Dissenting Shares, Parent shall not be required to deposit or cause to be deposited with the Exchange Agent any funds or shares of Parent Common Stock. Following the Effective Time, Parent agrees to make available to the Exchange Agent, from time to time as needed, cash in U.S. dollars sufficient to pay any dividends pursuant toSection 3.1(f) (Dividends). All cash and book-entry shares representing Parent Common Stock deposited with the Exchange Agent shall be referred to in this Agreement as the “Exchange Fund”. The Exchange Agent shall deliver the Stock Consideration (and any cash to be paid in lieu of any fractional share of Parent Common Stock in accordance withSection 3.5 (No Fractional Shares) or cash to be paid for dividends in accordance withSection 3.1(f)) out of the Exchange Fund. The Exchange Fund shall not be used for any other purpose. The Exchange Agent shall invest any cash included in the Exchange Fund as directed by Parent. Any interest and other income resulting from such investments shall be the property of, and paid to, Parent.

(b) Each holder of one or more Certificate(s) representing shares of Company Common Stock that have been converted into the right to receive the Merger Consideration, upon surrender to the Exchange Agent of such Certificate(s) (or effective affidavit of loss in lieu thereof), together with a properly completed letter of transmittal, duly executed and completed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Exchange Agent, will be entitled to receive in exchange therefor (i) the number of whole shares of Parent Common Stock (which shall be innon-certificated book-entry form unless a physical certificate is requested) representing, in the aggregate, the whole number of shares of Parent Common Stock, if any, that such holder has the right to receive pursuant toSection 2.6 (Effect on Capital Stock), (ii) if applicable, any cash to be paid in lieu of any fractional share of Parent Common Stock in accordance withSection 3.5 (No Fractional Shares) and (iii) if applicable, any dividends in accordance withSection 3.1(f) (Dividends), in each case, without interest (less any required Tax withholding). Until so surrendered, each such Certificate shall, after the Effective Time, represent for all purposes only the right to receive such (A) Merger Consideration, (B) cash in lieu of any fractional shares and (C) unpaid dividends. No holder of Book-Entry Shares shall be required to deliver a Certificate or completed letter of transmittal to the Exchange Agent to receive (1) the number of whole shares of Parent Common Stock (which shall be innon-certificated book-entry form unless a physical certificate is requested) representing, in the aggregate, the whole number of shares of Parent Common Stock, if any, that such holder has the right to receive pursuant toSection 2.6 (Effect on Capital Stock), (2) if applicable, any cash to be paid in lieu of any fractional share of Parent Common Stock in accordance withSection 3.5 (No Fractional Shares) and (3) if applicable, any dividends in accordance withSection 3.1(f) (Dividends), in each case, without interest (less any required Tax withholding). No interest shall be paid or accrued on any Merger Consideration, cash in lieu of fractional shares or unpaid dividends payable to holders of Certificates or Book-Entry Shares.

(c) With respect to Certificate(s), in the event of a transfer of ownership of any Certificate that is not registered in the transfer books of the Company as of the Effective Time, (i) any Stock Consideration, (ii) if applicable, any cash to be paid in lieu of any fractional share of Parent Common Stock in accordance withSection 3.5 (No Fractional Shares) and (iii) if applicable, any dividends in accordance withSection 3.1(f) (Dividends), in each case, may be issued or paid to such a transferee if the Certificate is presented to the Exchange Agent, properly endorsed or otherwise in proper form for transfer, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer Taxes have been paid or are not applicable, in each case, in form and substance, reasonably satisfactory to the Exchange Agent. With respect to Book-Entry Shares, issuance or payment of (1) any Stock Consideration, (2) if applicable, any cash to be paid in lieu of any fractional share of Parent Common Stock in accordance withSection 3.5 (No Fractional Shares) and (3) if applicable, any dividends in accordance withSection 3.1(f) (Dividends), in each case, shall only be made to the Person in whose name such Book-Entry Shares are registered in the stock transfer books of the Company as of the Effective Time.

(d) From and after the Effective Time, there shall be no further registration of transfers of shares of Company Common Stock. From and after the Effective Time, the holders of Certificates representing shares of Company Common Stock outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such shares of Company Common Stock except as otherwise provided in this Agreement or by applicable Law. If, after the Effective Time, Certificates are presented to the Exchange Agent or Parent, they shall be cancelled and exchanged for the consideration provided for, and in accordance with the procedures set forth, inArticle II and thisArticle III.

(e) Any portion of the Exchange Fund that remains unclaimed by the holders of shares of Company Common Stock one year after the Effective Time shall be returned to Parent, and any such holder who has not exchanged his or her shares of Company Common Stock for the Merger Consideration in accordance with thisSection 3.1 prior to that time shall thereafter look only to Parent for delivery of the Merger Consideration in respect of such holder’s shares of Company Common Stock. Notwithstanding the foregoing, neither Parent, Merger Sub, nor the Company shall be liable to any holder of shares of Company Common Stock for any Merger Consideration, cash in lieu of fractional shares or any unpaid dividends delivered to any Governmental Entity pursuant to applicable abandoned property Laws. Any Merger Consideration, cash in lieu of fractional shares or any unpaid dividends remaining unclaimed by holders of shares of Company Common Stock immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Entity shall, to the extent permitted by applicable Law, become the property of Parent free and clear of any claims or interest of any Person previously entitled thereto.

(f) No dividends with respect to shares of Parent Common Stock issued in the Merger shall be paid to the holder of any Certificates or Book-Entry Shares until such Certificates or Book-Entry Shares are surrendered or transferred, as applicable, as provided in thisSection 3.1. Following such surrender, subject to the effect of escheat or abandoned property (in accordance withSection 3.1(e)), Tax or other applicable Law, shall be paid, without interest, to the record holder of the shares of Parent Common Stock issued in exchange therefor (i) at the time of such surrender, all dividends payable in respect of such shares of Parent Common Stock with a record date after the Effective Time and a payment date on or prior to the date of such surrender and not previously paid and (ii) at the appropriate payment date, the dividends payable with respect to such shares of Parent Common Stock with a record date after the Effective Time but with a payment date subsequent to such surrender. For purposes of dividends in respect of shares of Parent Common Stock, all shares of Parent Common Stock to be issued pursuant to the Merger shall be entitled to dividends pursuant to the immediately preceding sentence as if issued and outstanding as of the Effective Time.

Section 3.2Lost, Stolen or Destroyed Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, 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 Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Stock Consideration, any cash to be paid in lieu of any fractional share of Parent Common Stock in accordance withSection 3.5 (No Fractional Shares) and, if applicable, any dividends in accordance withSection 3.1(f) (Dividends) to be paid in respect of the shares of Company Common Stock represented by such Certificate as contemplated by thisArticle III.

Section 3.3Withholding Rights. Each of Parent and the Surviving Corporation shall be entitled to deduct and withhold, or cause the Exchange Agent or Rights Agent, as applicable, to deduct and withhold, from the consideration otherwise payable to any Person pursuant to this Agreement, the CVR Agreement or otherwise such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign Tax Law. To the extent that amounts are so deducted or withheld and paid over to the applicable Governmental Entity or Taxing Authority, such deducted or withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of shares of Company Common Stock in respect of which such deduction and withholding was made.

Section 3.4Further Assurances. After the Effective Time, the officers and directors of the Surviving Corporation will be authorized to execute and deliver, in the name and on behalf of the Company and Merger Sub, any deeds, bills of sale, assignments or assurances and to take and do, in the name and on behalf of the Company or Merger Sub, as applicable, any other actions and things to vest, perfect or confirm of record or otherwise in the Surviving Corporation any and all right, title and interest in, to and under any of the rights, properties or assets acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger

Section 3.5No Fractional Shares. No certificates or scrips representing fractional shares of Parent Common Stock shall be issued in exchange for shares of Company Common Stock, no dividends of Parent shall relate to such fractional share interests and such fractional share interests shall not entitle the owner thereof to vote or to any rights of a stockholder of Parent. In lieu of such fractional share interests, Parent or the Exchange Agent shall pay to each holder of Company Common Stock an amount in cash equal to the product obtained by multiplying (a) the fraction of a share (after taking into account all shares of Company Common Stock held by such holder at the Effective Time and rounded to the nearest one thousandth when expressed in decimal form) of Parent Common Stock to which such holder would otherwise be entitled to receive pursuant toSection 2.6 (Effect on Capital Stock) by (b) the average of the volume weighted average price per share of Parent Common Stock on the Nasdaq Global Market (as reported in The Wall Street Journal or, if not reported therein, in another authoritative source mutually selected by Parent and the Company) on each of the 20 consecutive trading days ending with the second complete trading day prior to the Closing Date.

Section 7.5CompanyNo Solicitation.

(a) From the date hereof until the earlier of the Effective Time and the termination of this Agreement pursuant toSection 9.1, except as otherwise set forth in thisSection 7.5, the Company shall not, nor shall it authorize or permit any of the Company Subsidiaries to, and the Company shall use reasonable best efforts to cause its and its Subsidiaries’ respective Representatives not to, directly or indirectly (i) initiate or solicit or knowingly facilitate, knowingly induce or knowingly encourage any inquiry or the making of any proposal or offer that constitutes, or would reasonably be expected to lead to, a Takeover Proposal, (ii) enter into, continue or otherwise participate in any discussions or negotiations regarding, furnish to any Person any information or data with respect to, or cooperate in any way that would otherwise reasonably be expected to lead to, any proposal or offer that constitutes, or would reasonably be expected to lead to, any Takeover Proposal, (iii) submit to the stockholders of the Company for their approval or adoption any Takeover Proposal or (iv) agree or publicly announce an intention to take any of the foregoing actions.

The Company shall, and the Company shall cause the Company Subsidiaries and shall use reasonable best efforts to cause its and their respective Representatives to, immediately cease and cause to be terminated any existing activities, discussions or negotiations with any Persons or their Representatives conducted prior to the date of this Agreement with respect to any Takeover Proposal and will request the prompt return

or destruction of any confidential information previously furnished to such Persons in connection therewith and immediately terminate the access of each such Person and its Representatives to any electronic data room maintained by or on behalf of the Company or any of the Company Subsidiaries. Neither the Company nor any of the Company Subsidiaries shall modify, amend or terminate, or waive, release, fail to enforce or assign any provisions of, any confidentiality agreement (other than any standstill provision therein) to which it is a party relating to any Takeover Proposal or any inquiry, offer or proposal in connection therewith and shall enforce, to the fullest extent permitted under applicable Law, the provisions of any such agreement (other than any standstill provision therein). Without limiting the foregoing, any violation of the restrictions set forth in thisSection 7.5 by any Representative of the Company or any of the Company Subsidiaries shall be deemed to be a breach of thisSection 7.5 by the Company.

(b) Notwithstanding the foregoing, prior to receipt of the Company Stockholder Approval, the Company may, in response to a bona fide written Takeover Proposal that was first received after the date hereof, was unsolicited and did not result from a breach ofSection 7.5(a):

(i) furnish information with respect to the Company and the Company Subsidiaries to the Person making such Takeover Proposal and its Representatives pursuant to and in accordance with a confidentiality agreement containing provisions no less restrictive in any substantive respect than those contained in the Confidentiality Agreement;provided that such confidentiality agreement need not contain a standstill provision;provided,further, that all such information provided to such Person has previously been provided to Parent or is provided to Parent prior to or substantially concurrently with (and in any event on the same calendar day as) the time it is provided to such Person; and

(ii) participate in discussions or negotiations with such Person or its Representatives regarding such Takeover Proposal;

provided, in each case, that the Board of Directors of the Company determines in good faith (after consultation with its outside legal counsel and a financial advisor of nationally recognized reputation), that (i) after consultation with its outside legal counsel and a financial advisor of nationally recognized reputation (it being understood that the Company Financial Advisor is a financial advisor of nationally recognized reputation), such Takeover Proposal is, or would reasonably be expected to lead to, a Superior Proposal and (ii) after consultation with its outside legal counsel, the failure to furnish such information or participate in such discussions or negotiations with respect to such Takeover Proposal would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law.

(c) As promptly as reasonably practicable after the receipt, directly or indirectly, by the Company of any Takeover Proposal or any proposal, offer or inquiry with respect to, or that would reasonably be expected to lead to, any Takeover Proposal, and in any case within 24 hours after the receipt thereof, the Company shall provide oral and written notice to Parent of (i) such Takeover Proposal, proposal, offer or inquiry, (ii) the identity of the Person making any such Takeover Proposal, proposal, offer or inquiry and (iii) the economic and other material terms and conditions of any such Takeover Proposal, proposal, offer or inquiry (including an unredacted copy of all written materials provided by such Person to the Company in connection with such Takeover Proposal, proposal, offer or inquiry and any amendments or modifications thereto). The Company shall promptly (and in any event within 24 hours) keep Parent reasonably informed of any material developments with respect to any such Takeover Proposal, proposal, offer or inquiry (including any material changes thereto and copies of any additional written materials received by the Company, the Company Subsidiaries or their respective Representatives from the Person that submitted such Takeover Proposal or such proposal, offer or inquiry or such Person’s Representatives).

(d) Except as provided in thisSection 7.5(d), neither the Board of Directors of the Company nor any committee thereof shall, directly or indirectly, effect a Change in Recommendation. Notwithstanding the foregoing, at any time prior to receipt of the Company Stockholder Approval, the Board of Directors of the Company may, in response to a Superior Proposal (that has not been withdrawn) or an Intervening Event, effect a Change in Recommendation;provided that the Board of Directors of the Company determines in good faith (after consultation with its outside legal counsel and a financial advisor of nationally recognized reputation) that the failure to do so would be inconsistent with its fiduciary duties under applicable Law;provided,further, that the Board of Directors of the Company may not effect such a Change in Recommendation unless:

(i) the Board of Directors of the Company shall have first provided four Business Days’ prior written notice to Parent that it is prepared to effect a Change in Recommendation in response to a Superior Proposal or an Intervening Event (it being understood that delivery of such notice shall not in and of itself constitute a Change in Recommendation), which notice shall (A) in the case of a Superior Proposal, include the material terms and conditions of the Superior Proposal that is the basis of the proposed action of the Board of Directors of the Company (including the identity of the Person making such Superior Proposal and a written summary of any material terms and conditions communicated orally), and shall attach the most current unredacted version of the relevant Alternative Acquisition Agreement (if any) with the Person making such Superior Proposal and unredacted copies of any other documents evidencing or specifying any other terms and conditions of such Takeover Proposal received from, or provided by, the Person making such Superior Proposal and (B) in the case of an Intervening Event, state in reasonable detail the material facts underlying, and the rationale and basis for, the determination that an Intervening Event has occurred (it being understood and agreed that an amendment to the material terms of such Superior Proposal or a material change to the facts and circumstances that are the basis for such Intervening Event shall require an updated notice and a new three Business Day period pursuant to thisclause (i) during which period the Company shall be required to comply with thisSection 7.5(d) anew with respect to such additional notice);

(ii) during such four Business Day period, the Company and its Representatives, to the extent reasonably requested by Parent, engaged in good faith negotiations with Parent to amend this Agreement in such a manner (A) in the case of a Superior Proposal, that the Takeover Proposal ceases to constitute a Superior Proposal or (B) in the case of an Intervening Event, to obviate the need to effect a Change in Recommendation; and

(iii) after taking into account any revised terms offered in writing by Parent, the Board of Directors of the Company determines in good faith (A) in the case of a Superior Proposal, after consultation with its legal counsel and financial advisor, that such Takeover Proposal continues to constitute a Superior Proposal and (B) in the case of a Superior Proposal or Intervening Event, after consultation with its outside legal counsel, that the failure to make a Change in Recommendation would continue to be inconsistent with its fiduciary duties under applicable Law.

(e) Nothing contained in thisSection 7.5 shall prohibit the Company from complying with Rule14d-9, Rule14e-2 or Item 1012(a) of RegulationM-A promulgated under the Exchange Act in respect of any Takeover Proposal or making any disclosure to the stockholders of the Company if the Board of Directors of the Company determines in good faith (after consultation with its outside legal counsel) that the failure to make such disclosure would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law;provided,however, that any such action taken or statement made that relates to a Takeover Proposal shall not be deemed to be a Change in Recommendation if the Board of Directors of the Company reaffirms the Company Recommendation in such statement or in connection with such action;provided,further, that neither the Board of Directors of the Company nor any committee thereof shall, except as expressly permitted bySection 7.5(d) (Change in Recommendation), effect a Change in Recommendation.

(f) For purposes of this Agreement:

(i) “Intervening Event” means a Change that is material to the Company and the Company Subsidiaries, taken as a whole, which was not known by, or if known, the effect of which was not reasonably foreseeable by, the Board of Directors of the Company as of or prior to the date hereof (which Change does not relate to a Takeover Proposal), and which becomes known to the Board of Directors of the Company prior to the Company Stockholder Approval;provided,however that none of the following shall constitute, be deemed to contribute to or otherwise be taken into account in determining whether there has been a Intervening Event: (A) any changes in the market price or trading volume of Company Common Stock or Parent Common Stock, in and of itself; (B) the fact that, in and of itself, the Company or any of the Company Subsidiaries exceeds any internal or published projections, forecasts, estimates or predictions in respect of revenues, earnings or other financial or operating metrics for any period ending after the date of this Agreement (it being understood that the underlying facts giving rise or contributing to events described inclauses (A) and(B) may be taken into account in determining whether there has been an Intervening Event if such facts are not otherwise excluded under this definition); (C) any regulatory or clinical Changes relating to any Company Product (including (1) any regulatory actions, requests, recommendations or decisions of any Governmental Entity relating to any Company Product or any other regulatory or clinical development relating to any Company Product, and (2) any clinical trials, studies, tests or results or announcements thereof with respect to any Company Product); and (D) the research, development, testing, distribution, sale, supply, license, marketing, promotion, manufacturing or commercialization of any Company Product.

(ii) “Superior Proposal” means an unsolicited bona fide written Takeover Proposal that was first received after the date hereof that (x) did not result from a breach ofSection 7.5 and (y) the Board of Directors of the Company determines, in good faith, after consultation with its outside legal counsel and its financial advisor, (A) is reasonably likely to be consummated in accordance with its terms (if accepted), taking into account all legal, regulatory and financing aspects (including certainty of closing and, to the extent third party financing is required, that such financing is then fully committed on customary terms and conditions) of such Takeover Proposal and the Person making the proposal and other aspects of the Takeover Proposal that the Board of Directors of the Company deems relevant, and (B) if consummated, would result in a transaction more favorable from a financial point of view to the holders of Company Common Stock (solely in their capacity as such) than the Transactions;provided,however, that, for the purposes of this definition of “Superior Proposal,” the term “Takeover Proposal” shall have the meaning assigned to such term herein, except that references to “15%” in such definition shall be deemed to be references to “50%”.

(iii) “Takeover Proposal” means any inquiry, proposal or offer from any Person, other than Parent and the Parent Subsidiaries, relating to any (A) direct or indirect acquisition (whether in a single transaction or a series of related transactions) of assets of the Company or any of the Company Subsidiaries (including Securities of any Company Subsidiaries) equal to 15% or more of the consolidated assets of the Company and the Company Subsidiaries, or to which 15% or more of the revenues of the Company and the Company Subsidiaries on a consolidated basis are attributable for the most recent fiscal year in which audited financial statements are then available, (B) direct or indirect acquisition from the Company or issuance (whether in a single transaction or a series of related transactions) of 15% or more of any class of equity or voting securities of the Company, (C) tender offer or exchange offer that, if consummated, would result in such Person Beneficially Owning 15% or more of any class of equity or voting securities of the Company, or (D) merger, consolidation, share exchange, business combination, joint venture, reorganization, recapitalization, liquidation, dissolution or similar transaction or series of related transactions involving the Company or any of the Company Subsidiaries, under which (1) such Person would, directly or indirectly, acquire assets equal to 15% or more of the consolidated assets of the Company and the Company Subsidiaries, or to which 15% or more of the revenues of the Company and the Company Subsidiaries on a consolidated basis are attributable for the most recent fiscal year in which audited financial statements are then available, or (2) the stockholders or equityholders of such Person immediately after giving effect to such transaction(s) would Beneficially Own 15% or more of any class of equity or voting securities of the Company or the surviving or resulting entity in such transaction(s).

(b) Except to the extent necessary to avoid the duplication of benefits, the Surviving Corporation shall use commercially reasonable efforts to recognize the service of each Continuing Employee with the Company or its Affiliates before the Effective Time as if such service had been performed with Parent or its Affiliates (i) for purposes of eligibility and vesting under any employee benefit plans (including Parent’s 401(k) plan) and programs of the Parent, of the Surviving Corporation or any of their Affiliates (the “Surviving Corporation Plans”) in which the Continuing Employee participates after the Effective Time, and (ii) for benefit accrual purposes under any Surviving Corporation Plan that is a vacation or severance plan in which the Continuing Employee participates after the Effective Time;provided, that such recognition of service shall not apply for purposes of any plan or arrangement that is a defined benefit pension plan or that is grandfathered or frozen, either with respect to level of benefits or participation or for any post-retirement health or welfare plan.

From and after the Effective Time, any agreement of any Indemnified Person with the Company or any of its Subsidiaries regarding elimination of liability, indemnification or advancement of expenses shall be assumed by the Surviving Corporation, shall survive the Merger and shall continue in full force and effect in accordance with its terms.

(e) If Parent or the Surviving Corporation or any of its successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) transfers or conveys all or substantially all of its property and assets to any Person, then, and in each such case, proper provision shall be made so that the applicable successor, assign or transferee shall assume the obligations set forth in thisSection 7.8 (including thisSection 7.8(e)).

(i) the Board of Directors of Parent shall have first provided four Business Days’ prior written notice to the Company that it is prepared to effect a Parent Change in Recommendation in response to a Parent Superior Proposal or a Parent Intervening Event (it being understood that the delivery of such notice shall not in and of itself constitute a Parent Change in Recommendation), which notice shall (A) in the case of a Parent Superior Proposal, include the material terms and conditions of the Parent Superior Proposal that is the basis of the proposed action of the Board of Directors of Parent (including the identity of the Person making such Parent Superior Proposal and a written summary of any material terms and conditions communicated orally), and shall attach the most current unredacted version of the relevant Parent Alternative Acquisition Agreement (if any) with the Person making such Parent Superior Proposal and unredacted copies of any other documents evidencing or specifying any other terms and conditions of

(ii) during such four Business Day period, Parent and its Representatives, to the extent reasonably requested by the Company, engaged in good faith negotiations with the Company to amend this Agreement in such a manner (A) in the case of a Parent Superior Proposal, that the Parent Takeover Proposal ceases to constitute a Parent Superior Proposal or (B) in the case of a Parent Intervening Event, to obviate the need to effect a Parent Change in Recommendation; and

(iii) after taking into account any revised terms offered in writing by the Company, the Board of Directors of Parent determines in good faith (A) in the case of a Parent Superior Proposal, after consultation with its legal counsel and financial advisor, that such Parent Takeover Proposal continues to constitute a Parent Superior Proposal and (B) in the case of a Parent Superior Proposal or a Parent Intervening Event, after consultation with its outside legal counsel, that the failure to make a Parent Change in Recommendation would continue to be inconsistent with its fiduciary duties under applicable Law.

(e) Nothing contained in thisSection 7.19 shall prohibit Parent from complying with Rule14d-9, Rule14e-2 or Item 1012(a) of RegulationM-A promulgated under the Exchange Act in respect of any Parent Takeover Proposal or making any disclosure to the stockholders of Parent if the Board of Directors of Parent determines in good faith (after consultation with its outside legal counsel) that the failure to make such disclosure would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law;provided,however, that any such action taken or statement made that relates to a Parent Takeover Proposal shall not be deemed to be a Parent Change in Recommendation if the Board of Directors of Parent reaffirms the Parent Recommendation in such statement or in connection with such action;provided,further, that neither the Board of Directors of Parent nor any committee thereof shall, except as expressly permitted bySection 7.19(d) (Parent No Solicitation), effect a Parent Change in Recommendation.

otherwise be impossible to calculate with precision. In addition, if the Company fails to pay in a timely manner the Willful Breach Damages when due and payable pursuant to thisSection 9.2 (Effect of Termination), then (i) the Company shall reimburse Parent and Merger Sub for all costs and expenses (including disbursements and fees of counsel) incurred in the collection of such overdue amount, including in connection with any related Proceedings commenced and (ii) the Company shall pay to Parent and Merger Sub interest on the unpaid Willful Breach Damages from and including the date payment of such amount was due to but excluding the date of actual payment at the prime rate set forth in The Wall Street Journal in effect on the date such payment was required to be made plus 2%.

Section 10.3Interpretation. When a reference is made in this Agreement to Sections, Exhibits or Schedules, such reference shall be to a Section of or Exhibit or Schedule to this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation”. The words “made available” shall be deemed to mean that such information was included in the Company’s electronic data room or Parent’s electronic data room, as applicable, or was otherwise provided to the applicable Party (as demonstrated by reasonable documentation), prior to the execution and delivery of this Agreement. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms. The Parties have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as drafted jointly by the Parties and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Agreement. The words “hereby,” “herein,” “hereof,” “hereunder” and words of similar import refer to this Agreement as a whole (including any Exhibits hereto and Schedules delivered herewith) and not merely to the specific section, paragraph or clause in which such word appears. Whenever the context may require, any pronoun shall include the corresponding masculine, feminine and neuter forms. Except as otherwise expressly provided herein, all references to “Dollars” or “$” shall be deemed references to the lawful money of the United States of America. Any reference in this Agreement to a date or time shall be deemed to be such date or time in the City of New York, New York, U.S.A., unless otherwise specified. Any reference to a number of days shall refer to calendar days unless Business Days are specified. Any reference to “ordinary course of business” or any similar concept refers to the ordinary course of business of the Company and the Company Subsidiaries, taken as a whole, or of Parent and the Parent Subsidiaries, taken as a whole, in each case, consistent with past practices.

All terms defined in this Agreement have the defined meanings when used in any certificate or other document made or delivered pursuant hereto, unless otherwise defined therein. When reference is made herein to a Person, such reference shall be deemed to include all direct and indirect Subsidiaries of such Person unless

otherwise indicated or the context otherwise requires. The terms “or”, “any” and “either” are not exclusive. The word “extent” in the phrase “to the extent” shall mean the degree to which a subject or other thing extends, and such phrase shall not mean simply “if”.

Any agreement on the part of a Party to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such Party. The failure of any Party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of those rights.

hereof in any court of competent jurisdiction, this being in addition to any other remedy to which they are entitled at Law or in equity and (b) the right of specific enforcement is an integral part of the Transactions and without that right, neither the Company nor Parent would have entered into this Agreement. The Parties agree not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to Law or inequitable for any reason, and not to assert that a remedy of monetary damages would provide an adequate remedy or that the parties otherwise have an adequate remedy at Law. The Parties acknowledge and agree that any Party seeking an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in accordance with thisSection 10.11 shall not be required to provide any bond or other security in connection with any such order or injunction.
