ARTICLE I.

THE MERGER

1.1 The Merger. Pursuant to the terms and subject to the conditions of this Agreement, at the Effective Time (as defined below), the Company and Merger Sub shall consummate the Merger in accordance with the DGCL pursuant to which (a) Merger Sub shall be merged with and into the Company and the separate corporate existence of Merger Sub shall thereupon cease; (b) the Company shall be the successor or Surviving Corporation in the Merger; (c) the separate corporate existence of the Company with all its rights, privileges, immunities, powers and franchises shall continue unaffected by the Merger; and (d) the Company shall succeed to and assume all the rights and obligations of Merger Sub. The corporation surviving the Merger (and any successor or assign thereof) is sometimes hereinafter referred to as the “Surviving Corporation.” The Merger shall have the effects set forth in the applicable provisions of the DGCL.

1.2 Effective Time. Concurrently with the Closing on the Closing Date, the parties shall file a Certificate of Merger in the form attached hereto as Exhibit B (the “Certificate of Merger”) with the Secretary of State of the State of Delaware in accordance with the relevant provisions of the DGCL. The Merger shall become effective upon the filing and acceptance by the Secretary of State of the State of Delaware of the Certificate of Merger or at such later time as is agreed to by Parent and the Company and specified in the Certificate of Merger (the time at which the Merger becomes effective is herein referred to as the “Effective Time”). At the Effective Time, by virtue of the Merger and without any action of the part of Parent, Merger Sub, the Company or any other Person: (a) each share of common stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and exchanged for one share of common stock of the Surviving Corporation; and (b) each share of Company Capital Stock issued and outstanding immediately prior to the Effective Time shall be converted into the right to receive the consideration described in Section 1.5.

1.3 Effects of the Merger. At the Effective Time, and without any further action on the part of Parent, Merger Sub, the Company or any other Person:

(a) the certificate of incorporation of the Company, as in effect immediately prior to the Effective Time (the “Company Certificate”), shall be amended and restated in the Merger to read as set forth on Exhibit A to the Certificate of Merger, and, as so amended and restated, such certificate of incorporation shall be the certificate of incorporation of the Surviving Corporation until thereafter amended as provided therein or by applicable Law;

2

(b) the bylaws of the Company, as in effect immediately prior to the Effective Time, shall be amended and restated in the Merger to read as set forth on Exhibit C, and, as so amended and restated, such bylaws shall be the bylaws of the Surviving Corporation until thereafter amended as provided therein or by applicable Law; and

(c) the Merger shall, from and after the Effective Time, have all of the effects provided by the DGCL and applicable Law. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all the properties, rights, privileges and powers of the Company and Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of the Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation.

1.4 Subsequent Actions. If at any time after the Effective Time the Surviving Corporation shall determine, in its sole discretion, or shall be advised, that any deeds, bills of sale, instruments of conveyance, assignments, assurances or any other actions or things are necessary or desirable to vest, perfect or confirm of record or otherwise in the Surviving Corporation its right, title or interest in, to or under any of the rights, properties or assets of the Company acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger or otherwise to carry out this Agreement, then the officers of the Surviving Corporation shall be authorized to execute and deliver, in the name and on behalf of the Company, all such deeds, bills of sale, instruments of conveyance, assignments and assurances and to take and do, in the name and on behalf of the Company or otherwise, all such other actions and things as may be necessary or desirable to vest, perfect or confirm any and all right, title or interest in, to and under such rights, properties or assets in the Surviving Corporation or otherwise to carry out this Agreement.

1.5 Conversion of Company Capital Stock.

(a) Company Restricted Shares.

(i) Continuing Employees. Upon the terms and subject to the conditions of this Section 1.5 and elsewhere in this Agreement, at the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Company or the holders of shares of Company Capital Stock, each Company Restricted Share (other than Dissenting Shares) that is held, as of immediately prior to the Effective Time, by a Continuing Employee will vest in full and all restrictions, forfeiture conditions and repurchase rights with respect thereto shall lapse, and each such Company Restricted Share will be cancelled and will be converted automatically into the non-transferable right to receive the Per Share Closing Stock Consideration; provided, that each Parent Series B Preferred Share issued pursuant to this Section 1.5(a)(i), including any Parent Series B Preferred Shares released from the Indemnification Holdback Amount or the Roche Holdback Amount in respect of such Company Restricted Share, shall remain subject to the Company Plan or agreement pursuant to which the Company Restricted Share was issued and continue to have, and be subject to, substantially similar terms and conditions (excluding vesting terms, accelerated vesting provisions, risk of forfeiture, but including the right of first refusal, and transfer restrictions) as applied to the applicable Company Restricted Share immediately prior to the Effective Time. At the Effective Time, Parent shall assume the Company Plan and each agreement evidencing a Company Restricted Share that is issued pursuant to this Section 1.5(a)(i).

(ii) Non-Continuing Employees. Upon the terms and subject to the conditions of this Section 1.5 and elsewhere in this Agreement, at the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Company or the holders of shares of Company Capital Stock, each Company Restricted Share (other than Dissenting Shares) that is held, as of immediately prior to the Effective Time, by a Non-Continuing Employee will vest in full and all restrictions, forfeiture conditions and repurchase rights with respect thereto shall lapse, and each such Company Restricted Share will be cancelled and will be converted automatically into the non-transferable right to receive (A) if such Non-Continuing Employee is an Accredited Person, the consideration specified for a share of Company Capital Stock in Section 1.5(b)(i) and (B) if such Non-Continuing Employee is a Non-Accredited Person, the consideration specified for a share of Company Capital Stock in Section 1.5(b)(ii).

(b) Company Non-Restricted Shares.

(i) Shares Held by Accredited Investors. Upon the terms and subject to the conditions of this Section 1.5 and elsewhere in this Agreement, at the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Company or the holders of shares of Company Capital Stock, each share of Company Capital Stock (other than Company Restricted Shares held by Continuing Employees and Dissenting Shares) issued and outstanding immediately prior to the Effective Time that is held by a Person who is an Accredited Investor (an “Accredited Person”) will be cancelled and will be converted automatically into the non-transferable right to receive the Per Share Closing Stock Consideration.

(ii) Shares Held by Non-Accredited Investors. Upon the terms and subject to the conditions of this Section 1.5 and elsewhere in this Agreement, at the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Company or the holders of shares of Company Capital Stock, each share of Company Capital Stock (other than Company Restricted Shares held by Continuing Employees and Dissenting Shares) issued and outstanding immediately prior to the Effective Time that is held by a Person who is not an Accredited Investor (a “Non-Accredited Person”) will be cancelled and will be converted automatically into the non-transferable right to receive an amount in cash equal to the Per Share Closing Cash Consideration.

(c) No Further Ownership Rights in Company Securities. At the Effective Time, each holder of issued and outstanding Company Capital Stock immediately prior to the Effective Time shall cease to have any rights as a holder of securities of the Company. After the Effective Time, there shall be no further registration of transfers on the transfer books of the Surviving Corporation of the Company Capital Stock outstanding immediately prior to the Effective Time. If, after the Effective Time, a valid certificate previously representing any of such shares of Company Capital Stock (a “Company Stock Certificate”) is presented to the Surviving Corporation or Parent, such Company Stock Certificate shall be canceled (as applicable) and shall be exchanged as provided in Section 1.7.

4

(d) No Fractional Shares. No fractional Parent Series B Preferred Shares shall be issued in connection with the Merger, and the number of Parent Series B Preferred Shares issuable to each Company Stockholder pursuant to Sections 1.5, 1.8, 1.9, 8.8 or elsewhere in this Agreement shall be rounded down to the nearest whole number of Parent Series B Preferred Shares for each such issuance, with no cash being paid for any fractional share eliminated by such rounding.

1.6 Dissenting Shares. Notwithstanding anything in this Agreement to the contrary, shares of Company Capital Stock that are issued and outstanding immediately prior to the Effective Time and that are held by Company Stockholders properly exercising appraisal rights available under Section 262 of the DGCL (the “Dissenting Shares”) shall not be converted into or be exchangeable for the right to receive any consideration pursuant to Section 1.5, unless and until such holders shall have failed to perfect or shall have effectively withdrawn or lost their rights to appraisal under the DGCL. Dissenting Shares shall be treated in accordance with Section 262 of the DGCL. If any such holder shall have failed to perfect or shall have effectively withdrawn or lost such right to appraisal, such holder’s shares of Company Capital Stock shall thereupon be converted into and become exchangeable only for the right to receive, as of the later of the Effective Time and the time that such right to appraisal shall have been irrevocably lost, withdrawn or expired, the consideration in respect thereof set forth in Section 1.5, without any interest thereon. The Company shall give Parent and Merger Sub (a) prompt notice of any written demands for appraisal of any shares, attempted withdrawals of such demands and any other instruments served pursuant to the DGCL and received by the Company relating to rights to be paid the “fair value” of Dissenting Shares, as provided in Section 262 of the DGCL and (b) the opportunity to direct all negotiations and proceedings with respect to demands for appraisal under the DGCL. The Company shall not, except with the prior written consent of Parent (which shall not be unreasonably withheld, conditioned or delayed), voluntarily make or agree to make any payment with respect to any demands for appraisals of Company Capital Stock, offer to settle or settle any such demands or approve any withdrawal of any such demands.

1.7 Surrender Procedures.

(a) Prior to the Effective Time, Parent shall appoint U.S. Bank National Association as the exchange agent in the Merger (the “Exchange Agent”). Promptly after the Effective Time, the Exchange Agent shall send, to each Company Stockholder that has not delivered a Letter of Transmittal and Accredited Investor Certification to Parent prior to the Effective Time, at the address and email address provided by the Company in the Consideration Schedule a letter of transmittal in the form of Exhibit D attached hereto (the “Letter of Transmittal”) for use in such exchange. The parties acknowledge that the terms of the Letter of Transmittal include (i) an agreement to be bound by the terms of this Agreement, including Article VIII and Section 9.20 hereof, (ii) a written certification of status as an “accredited investor” within the meaning of Securities and Exchange Commission Rule 501 of Regulation D, as presently in effect, under the Securities Act, in the form of Exhibit E attached hereto (an “Accredited Investor Certification”), (iii) a joinder to the Parent Investor Agreements for Stock Converting Holders, (iv) a release of claims against the Company and related parties and (v) instructions for use in effecting the surrender of Company Stock Certificates.

5

(b) On the Closing Date, Parent shall deposit (or cause to be deposited) with the Exchange Agent an amount of cash sufficient to pay the aggregate Per Share Closing Cash Consideration payable hereunder (other than any such amounts which are payable through the Surviving Corporation’s or Parent’s payroll system pursuant to this Agreement). The Exchange Agent shall hold such funds and deliver them in accordance with the terms and conditions hereof and the terms and conditions of an Exchange Agent Agreement in a form to be provided by Parent and reasonably acceptable to the Company (the “Exchange Agent Agreement”).

(c) Upon surrender of a Company Stock Certificate for cancellation to the Exchange Agent, together with the Letter of Transmittal, duly completed and validly executed in accordance with the instructions thereto, the holder of such Company Stock Certificate shall be entitled to receive in exchange for each share of Company Capital Stock formerly represented by such Company Stock Certificate, upon the terms and subject to the conditions set forth in this Agreement, the Per Share Closing Stock Consideration or Per Share Closing Cash Consideration, as applicable, payable in respect of such share of Company Capital Stock pursuant to Section 1.5, and the Company Stock Certificate so surrendered shall forthwith be canceled. The Exchange Agent shall, promptly after receipt of each properly surrendered Company Stock Certificate, (i) cause the Per Share Closing Cash Consideration, if any, payable with respect to each share represented by such Company Stock Certificate to be sent by wire transfer of immediately available funds to the account designated by such holder in the Letter of Transmittal delivered with such Company Stock Certificate and (ii) instruct Parent to issue the Per Share Closing Stock Consideration (which, for the avoidance of doubt, may be delivered in a book-entry or similar position), if any, issuable with respect to each share represented by such Company Stock Certificate. Until so surrendered, each outstanding Company Stock Certificate that prior to the Effective Time represented shares of Company Capital Stock will be deemed from and after the Effective Time, for all purposes, to evidence only the right to receive upon such surrender the Per Share Closing Consideration (upon the terms and subject to the conditions set forth in this Agreement).

(d) If any Company Stock Certificate shall have been lost, stolen or destroyed, Parent may, in its discretion and as a condition precedent to the payment of any portion of the Per Share Closing Consideration, require the owner of such lost, stolen or destroyed Company Stock Certificate to provide an appropriate affidavit, which affidavit will include an obligation to indemnify Parent and the Surviving Corporation against any claim that may be made against Parent or the Surviving Corporation with respect to such Company Stock Certificate.

(e) Notwithstanding anything to the contrary in this Agreement, none of Parent, the Surviving Corporation or the Exchange Agent shall be liable to any holder or former holder of shares of Company Capital Stock for the Per Share Closing Consideration attributable to each of such shares or for any other cash amounts, delivered to any public official pursuant to any applicable abandoned property, escheat or similar Law.

(f) Any portion of the consideration payable to Company Stockholders hereunder that is held by the Exchange Agent and remains undistributed to Company Stockholders as of the first anniversary of this Agreement shall be delivered to Parent upon demand, and Company Stockholders who have not theretofore surrendered their Company Stock Certificates in accordance with this Section 1.7 shall thereafter look only to Parent for satisfaction of their claims for any consideration payable with respect to the shares of Company Capital Stock previously represented by such Company Stock Certificates without any interest thereon.

1.8 Indemnification Holdback Release. Notwithstanding anything to the contrary in this Article I or elsewhere in this Agreement, Parent shall withhold from each Company Stockholder’s applicable portion of the aggregate Per Share Closing Cash Consideration or Per Share Closing Stock Consideration payable or issuable, as applicable, to such Company Stockholder pursuant to Section 1.5, such Company Stockholder’s Pro Rata Share of the Indemnification Holdback Amount (which such amount shall be withheld in the form of cash for each Cash Converting Holder and in the form of Parent Series B Preferred Shares issued in the name of the Company Stockholder at Closing for each Stock Converting Holder (with such Parent Series B Preferred Shares valued at the Parent Per Share Price)). The Indemnification Holdback Amount shall constitute partial security for the benefit of Parent (on behalf of itself or any other Parent Indemnified Party) in respect of the indemnification obligations of the Company Stockholders under Section 8.2, and shall be held and distributed in accordance with Section 8.8. The adoption of this Agreement and the approval of the Merger by the Company Stockholders shall constitute, among other things, approval of the (a) Indemnification Holdback Amount, (b) the withholding of the Indemnification Holdback Amount by Parent and (c) the appointment of the Stockholders’ Representative.

1.9 Roche Release.

(a) Notwithstanding anything to the contrary in this Article I or elsewhere in this Agreement, Parent shall withhold from each Company Stockholder’s applicable portion of the aggregate Per Share Closing Cash Consideration or Per Share Closing Stock Consideration payable or issuable, as applicable, to such Company Stockholder pursuant to Section 1.5, such Company Stockholder’s Pro Rata Share of the Roche Holdback Amount (which such amount shall be withheld in the form of cash for each Cash Converting Holder and in the form of Parent Series B Preferred Shares issued in the name of the Company Stockholder at Closing for each Stock Converting Holder (with such Parent Series B Preferred Shares valued at the Parent Per Share Price)). The Roche Holdback Amount shall be held and distributed in accordance with this Section 1.9. The adoption of this Agreement and the approval of the Merger by the Company Stockholders shall constitute, among other things, approval of the (a) Roche Holdback Amount and (b) the withholding of the Roche Holdback Amount by Parent. The Company Stockholders shall not receive interest on the Roche Holdback Amount. Neither the Roche Holdback Amount (including any portion thereof) nor any beneficial interest therein may be pledged, subjected to any Encumbrance, sold, assigned or transferred by any Company Stockholder, or be taken or reached by any legal or equitable process in satisfaction of any debt or other liability of any Company Stockholder, in each case prior to the release of the Roche Holdback Amount to any Company Stockholder in accordance with this Section 1.9. For the avoidance of doubt, any Parent Series B Preferred Shares deemed withheld from the Stock Converting Holders in respect of the Roche Holdback Amount in accordance with this Section 1.9 shall be issued and outstanding stock of Parent, which Parent shall hold in escrow on behalf of the Stock Converting Holders pending release under this Section 1.9. The Stock Converting Holders shall be entitled to exercise voting rights and shall be entitled to receive any dividends with respect to such shares until such time, if any, as such shares are cancelled by Parent as provided in this Section 1.9.

(b) If and only if the Roche Interim Release Event has occurred, as soon as reasonably practicable following the occurrence of the Roche Interim Release Event (but in no event later than thirty (30) days following such date), Parent shall, upon the terms and subject to the conditions of Section 1.7 and elsewhere in this Agreement, [***].

(d) During the Roche Interim Period and, if applicable, the Roche Secondary Period, [***].

(e) For the avoidance of doubt, in no event shall Parent be obligated to [***].

1.10 Tax Consequences. For U.S. federal income tax purposes, it is intended that the Merger qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and the regulations promulgated thereunder. This Agreement is intended to constitute, and the parties hereto hereby adopt this Agreement as, a “plan of reorganization” for purposes of Sections 354, 361 and 368 of the Code. For the avoidance of doubt, however, neither Parent nor Merger Sub (nor any Representative thereof) has provided or will provide any representations or warranties regarding the tax consequences of the Merger and the transactions contemplated hereunder or any tax advice. Each party hereto shall prepare its Tax Returns relating to the Merger in a manner consistent with the foregoing intent, unless otherwise required by applicable law.

1.11 Withholding. Each of Parent, Merger Sub, the Surviving Corporation, the Exchange Agent and any other applicable withholding agent shall be entitled to deduct or withhold from the amounts payable or issuable (including Parent Series B Preferred Shares deliverable) under this Agreement such amounts as such Person is required to deduct or withhold in accordance with the Code and any other applicable Law. Any such withheld or deducted amount shall be timely paid over to the appropriate Governmental Authority and treated as though such amount had been paid to the Person in respect of whom such withholding was determined to be necessary. Any compensatory payments contemplated to be made hereunder shall be made through the payroll procedures of the applicable Person.

38

(b) Prior to the Effective Time, the Company shall purchase tail insurance coverage (the “Tail Insurance Coverage”) for the Company Indemnified Parties in a form reasonably satisfactory to the Company and Parent, which shall provide the Company Indemnified Parties with coverage for six (6) years following the Closing Date in an amount not less than the existing coverage and that shall have other terms not materially less favorable to the insured persons than the directors’ and officers’ liability insurance coverage maintained by the Company as of the date of this Agreement.

(c) The provisions of this Section 5.5 shall survive the Closing and are intended to be for the benefit of, and enforceable by, the Company Indemnified Parties, and shall be binding on all successors and assigns of the Surviving Corporation and Parent.

39

(c) Notwithstanding anything herein to the contrary in this Section 5.6, no access or examination contemplated by this Section 5.6 shall be permitted to the extent that it would require the Company or its Subsidiaries to waive the attorney-client privilege or attorney work product privilege, or violate any applicable Law; provided, that the Company (i) shall be entitled to withhold only such information that may not be provided without causing such violation or waiver, (ii) shall provide to Parent all related information that may be provided without causing such violation or waiver (including, to the extent permitted, redacted versions of any such information), and (iii) shall enter into such effective and appropriate joint-defense agreements or other protective arrangements as may be reasonably requested by Parent in order that all such information may be provided to Parent without causing such violation or waiver.

ARTICLE VII.

TERMINATION

7.1. Termination. This Agreement may be terminated and the Merger may be abandoned at any time prior to the Effective Time (notwithstanding the Requisite Stockholder Approval):

(a) by mutual written agreement of the Company and Parent;

(b) by either the Company or Parent, if the Merger has not been consummated on or before December 14, 2018 (the “End Date”); provided that the right to terminate this Agreement pursuant to this Section 7.1(b) shall not be available to any party whose breach of any provision of this Agreement is a proximate cause in the failure of the Merger to be consummated by such time;

46

(c) by either Parent or the Company, if a Governmental Authority shall have issued any Order or taken any other action, in each case, which has become final and non-appealable and which restrains, enjoins or otherwise prohibits the Merger;

(d) by Parent, if (i) any representation or warranty of the Company contained in this Agreement shall be inaccurate such that the condition set forth in Section 6.2(a) would not be satisfied, or (ii) the covenants or obligations of the Company contained in this Agreement shall have been breached in any material respect such that the condition set forth in Section 6.2(b) would not be satisfied; provided, however, that if an inaccuracy or breach is curable by the Company during the 30-day period after Parent notifies the Company in writing of the existence of such inaccuracy or breach (the “Company Cure Period”), then Parent may not terminate this Agreement under this Section 7.1(d) as a result of such inaccuracy or breach prior to the expiration of the Company Cure Period unless the Company is no longer continuing to exercise commercially reasonable efforts to cure such inaccuracy or breach;

(e) by the Company, if (i) any representation or warranty of Parent contained in this Agreement shall be inaccurate such that the condition set forth in Section 6.1(a) would not be satisfied, or (ii) the covenants or obligations of Parent or Merger Sub contained in this Agreement shall have been breached in any material respect such that the condition set forth in Section 6.1(b) would not be satisfied; provided, however, that if an inaccuracy or breach is curable by Parent or Merger Sub during the 30-day period after the Company notifies Parent in writing of the existence of such inaccuracy or breach (the “Parent Cure Period”), then the Company may not terminate this Agreement under this Section 7.1(e) as a result of such inaccuracy or breach prior to the expiration of the Parent Cure Period unless Parent is no longer continuing to exercise commercially reasonable efforts to cure such inaccuracy or breach;

(f) by Parent at any time before the Requisite Stockholder Approval has been obtained; provided, that Parent shall not be permitted to terminate pursuant to this Section 7.1(f) during the first 48 hours after the execution of this Agreement.

7.2. Effect of Termination. If this Agreement is terminated pursuant to Section 7.1, this Agreement shall become void and of no effect without liability of any party (or any Representative of such party) to any other party; provided that the parties shall, in all events, remain bound by and continue to be subject to the provisions set forth in Section 5.7 and Article IX, which shall survive any termination of this Agreement.

ARTICLE VIII.

INDEMNIFICATION

8.1. Survival. If the Merger is consummated, each and every representation, warranty, covenant, agreement and indemnity contained in this Agreement, the Parent Disclosure Schedule, the Company Disclosure Schedule, the certificate of Parent delivered pursuant to Section 6.1(e)(i) and the certificate of the Company delivered pursuant to Section 6.2(h)(i) shall survive execution and delivery of this Agreement and the Closing; provided, however, that the representations and warranties of the parties contained in Articles III and IV of this Agreement shall only survive the Closing until twelve (12) months after the Closing Date, other than Company Fundamental Representations and Parent Fundamental Representations which shall survive the

47

Closing until five (5) years after the Closing Date (the “Fundamental Representations”), and those set forth in Section 3.17 (Tax Matters), which shall survive until the date that is 60 days following the expiration of the applicable statute of limitations (including any applicable extensions). All covenants of the parties contained in this Agreement shall remain operative and in full force and effect in accordance with their terms or until fully performed. Notwithstanding the foregoing, (i) the expiration of the above survival periods for any representation or warranty shall not terminate or affect any claim with respect to such representation or warranty that is set forth in a Third-Party Notice of Claim or a Notice of Claim delivered to the other party in accordance with Section 8.6(b) or Section 8.6(e), as applicable, prior to the end of such survival period; and (ii) in the event of fraud (with the element of scienter) by or on behalf the Company on the one hand, or Parent or Merger Sub on the other hand, in connection with a representation or warranty contained in Articles III and IV of this Agreement, such representation or warranty (and the associated right of indemnity) shall survive until the date that is 60 days following the expiration of the applicable statute of limitations (including any applicable extensions) applicable to claims based on such fraud. The right to indemnification or other remedy based on the representations, warranties, covenants, agreements and indemnities contained herein will not be affected by any investigation conducted, or any knowledge acquired (or capable of being acquired), at any time, whether before or after the execution and delivery of this Agreement or the Closing Date, with respect to the accuracy or inaccuracy of or compliance with, any representation, warranty, covenant or agreement contained herein or any other matter.

8.2. Indemnification by Company Stockholders.

(a) From and after the Closing, each Company Stockholder shall severally, not jointly and severally, and in proportion to their respective Pro Rata Share, hold harmless and indemnify each of Parent and its Affiliates (including the Surviving Corporation after the Closing) and each of their respective officers, directors, employees, successors and assigns (collectively, the “Parent Indemnified Parties”) from and against any and all Losses arising out of or resulting from:

(i) any breach of or inaccuracy in any representation or warranty made by the Company pursuant to Article III or the certificate delivered by the Company pursuant to Section 6.2(h)(i) (without giving effect to any Material Adverse Effect or other materiality qualification or any similar qualification contained or incorporated directly or indirectly in such representation or warranty);

(ii) any breach of any covenant or agreement made by the Company under this Agreement that was to be performed by the Company at or prior to the Closing;

(iii) any inaccuracy in the Consideration Schedule or the Estimated Closing Statement;

(iv) any Closing Indebtedness or Unpaid Transaction Expenses to the extent not either (A) fully discharged at Closing, or (B) accounted for in the determination of Aggregate Closing Parent Shares; or

48

(v) the exercise of dissenters’ rights or rights of appraisal by any Company Stockholder or former Company Stockholder to the extent that the aggregate amount paid with respect to any Dissenting Shares, together with the aggregate amount of all Losses with respect thereto, exceeds the consideration that otherwise would have been payable to such Company Stockholder pursuant to Section 1.5 upon the exchange of such Dissenting Shares if such Company Stockholder had not exercised his, her or its right to dissent to the Merger pursuant to Section 262 of the DGCL.

(b) Notwithstanding anything to the contrary in this Agreement, the right to indemnification under this Section 8.2 is subject to the following limitations; provided, however, that the following limitations described in clauses (i) and (ii) below shall not apply to Losses arising out of or resulting from fraud (with the element of scienter) by or on behalf of the Company:

(i) Company Stockholders shall not have any obligation to indemnify any Parent Indemnified Party from and against any Losses arising out of breaches or inaccuracies indemnified under Section 8.2(a)(i) (other than as a result of a breach of or inaccuracy in a Company Fundamental Representation) until the Parent Indemnified Parties have suffered aggregate Losses by reason of such breaches or inaccuracies in excess of $250,000 (the “Deductible”) (it being understood that if aggregate Losses exceed the Deductible, then the Parent Indemnified Parties shall be entitled to be indemnified against only the portion of the aggregate Losses that exceed the Deductible). For the avoidance of doubt, the rights of Parent Indemnified Parties to indemnification pursuant to Section 8.2(a)(i) as a result of a breach of or inaccuracy in a Company Fundamental Representation shall not be subject to the Deductible.

(ii) The maximum amount which the Parent Indemnified Parties may recover arising out of breaches or inaccuracies described in Section 8.2(a)(i) (other than as a result of a breach of or inaccuracy in a Company Fundamental Representation) shall be an aggregate amount equal to the Indemnification Holdback Amount (the “Cap”) and recovery from the Indemnification Holdback Amount shall be the sole and exclusive remedy under this Agreement for any breaches or inaccuracies described in Section 8.2(a)(i) (other than as a result of a breach of or inaccuracy in a Company Fundamental Representation). For the avoidance of doubt, the Parent Indemnified Parties’ right to indemnification under Section 8.2(a)(i) as a result of a breach of or inaccuracy in a Company Fundamental Representation shall not be subject to the Cap.

(c) Subject to the other limitations contained herein, the Parent Indemnified Parties shall satisfy any finally determined claim for indemnification under this Section 8.2 (i) first, by permanently retaining such Losses from the Indemnification Holdback Amount as described in Section 8.8(b) and by therefore reducing the portion of the Indemnification Holdback Amount to be released to Company Stockholders pursuant to Section 8.8(c); and (B) second, with respect to aggregate indemnifiable Losses in excess of the Indemnification Holdback Amount, the Parent Indemnified Parties may satisfy any such Losses directly from such Company Stockholders in an amount not to exceed each such Company Stockholder’s Pro Rata Share of

49

such Losses; provided, that Parent may also offset any indemnifiable Losses for which any Parent Indemnified Party is entitled to be indemnified hereunder, after the Parent Indemnified Parties have exhausted all of the Indemnification Holdback Amount, against all or a portion of any payment of the Roche Interim Release Amount or Roche Secondary Release Amount otherwise payable to the Company Stockholders pursuant to Section 1.9 (with each Parent Series B Preferred Share offset thereby deemed to satisfy an amount of Losses equal to the Adjusted Parent Stock Price).

(d) Notwithstanding anything to the contrary in Section 8.2(c) or Section 8.8(b), in the event that the Parent Indemnified Parties are entitled to recover Losses in connection with a finally determined Parent Indemnity Claim, from the Indemnification Holdback Amount or otherwise, Parent shall provide written notice (“Indemnity Election Notice”) to the Stockholders’ Representative promptly following the date upon which such Parent Indemnity Claim is finally determined specifying (i) the Losses that the Parent Indemnified Parties are entitled to recover (the “Applicable Indemnifiable Amount”), (ii) each Company Stockholder’s Pro Rata Share of the Applicable Indemnifiable Amount, and (iii) the Adjusted Parent Stock Price applicable to such finally determined Parent Indemnity Claim. With respect to any Applicable Indemnifiable Amount, each Stock Converting Holder shall be entitled, at such Stock Converting Holder’s election, to deliver to the Stockholders’ Representative prior to the tenth (10^th) Business Day after Parent has delivered the Indemnity Election Notice to the Stockholders’ Representative an amount of cash to be applied to such Applicable Indemnifiable Amount equal to such Stock Converting Holder’s Pro Rata Share of the Applicable Indemnifiable Amount (such amount, with respect to any Stock Converting Holder, such Stock Converting Holder’s “Voluntary Cash Payment”). With respect to any Applicable Indemnifiable Amount, in the event that Parent receives from the Stockholders’ Representative, prior to the fifteen (15^th) Business Day after Parent has delivered the Indemnity Election Notice to the Stockholders’ Representative, (x) any Voluntary Cash Payments and (y) a written statement specifying the amount, if any, of such Voluntary Cash Payments paid by and therefor attributable to each Stock Converting Holder in respect of such Applicable Indemnifiable Amount, then Parent shall (A) first set-off against such Applicable Indemnifiable Amount the aggregate amount of such Voluntary Cash Payments, on a dollar-for-dollar basis, which aggregate amount shall be thereupon deemed to be paid over to, and owned by, Parent; (B) then, if applicable, release to each Stock Converting Holder that paid such a Voluntary Cash Payment in respect of such Applicable Indemnifiable Amount a number of the Parent Series B Preferred Shares out of the Indemnification Holdback Amount equal to such Stock Converting Holder’s Voluntary Cash Payment divided by the Adjusted Parent Stock Price applicable to such finally determined Parent Indemnity Claim; and (C) finally set-off against any remaining Applicable Indemnifiable Amount any Parent Series B Preferred Shares, on a dollar-for-dollar basis, determined using the Adjusted Parent Stock Price applicable to such finally determined Parent Indemnity Claim, such Parent Series B Preferred Shares to be returned to the authorized but unissued shares of Parent.

(e) Upon the consummation of a Parent IPO at any time from and after the Closing Date, the per share price to be used to value Parent Series B Preferred Shares in order to determine the amount of Losses deemed to be satisfied by such Parent Series B Preferred Shares (either with respect to Parent Series B Preferred Shares to be cancelled by Parent pursuant to Section 8.2(c) or to be issued to Company Indemnified Parties pursuant to Section 8.3(b)(iii)) shall be the greater of (i) $2.06 per share or (ii) an amount equal to the closing price of a share of Parent

50

Common Stock on the applicable nationally recognized stock exchange as of the last trading day preceding the date of submission of a Third Party Claim Notice or Notice of Claim, as applicable (the “Adjusted Parent Stock Price”); provided, that the Adjusted Parent Stock Price shall also be equitably adjusted (without duplication to any other equitable adjustment contemplated by this Agreement) to reflect any conversion of Parent Series B Preferred Shares into shares of Parent Common Stock other than on a one-for-one basis and/or any stock splits or reverse stock splits which occur in connection with such Parent IPO.

(f) Notwithstanding anything in this Agreement to the contrary, in no event shall any Company Stockholder have any liability pursuant to this Section 8.2 greater than the amount of consideration actually received by such Company Stockholder pursuant to Sections 1.5, 1.9 and 8.8(c) of this Agreement (inclusive of each Company Stockholder’s contributions to the Roche Holdback Amount and the Indemnification Holdback Amount) (with any Parent Series B Preferred Shares valued at the Parent Per Share Price).

(g) No Company Stockholder shall be liable to any Parent Indemnified Party (i) for the breach by any other Company Stockholder of any agreement entered into in connection with this Agreement, or (ii) any fraud (with the element of scienter) by any other Person (except for such fraud committed by or on behalf of the Company).

8.3. Indemnification by Parent and the Surviving Corporation.

(a) From and after the Closing, Parent and the Surviving Corporation will, jointly and severally, hold harmless and indemnify each Company Stockholder and its Affiliates and each of their respective officers, directors, employees, successors and assigns (collectively, the “Company Stockholder Indemnified Parties” and, together with the Parent Indemnified Parties, the “Indemnified Parties”) from and against any and all Losses arising out of or resulting from:

(i) any breach of or inaccuracy in any representation or warranty made by Parent or Merger Sub pursuant to Article IV or the certificates delivered by Parent and Merger Sub pursuant to Section 6.1(e)(i) (without giving effect to any Material Adverse Effect or other materiality qualification or any similar qualification contained or incorporated directly or indirectly in such representation or warranty); or

(ii) any breach of covenant or agreement made by Parent or Merger Sub under this Agreement that was to be performed by Parent or Merger Sub at or prior to the Closing.

(b) Notwithstanding anything to the contrary in this Agreement, the right to indemnification under this Section 8.3 is subject to the following limitations; provided, however, that the following limitations described in clauses (i) and (ii) below shall not apply to Losses arising out of or resulting from fraud (with the element of scienter) by or on behalf of Parent or Merger Sub:

(i) Parent and the Surviving Corporation shall not have any obligation to indemnify any Company Stockholder Indemnified Party from and against any Losses arising out of breaches or inaccuracies indemnified under Section 8.3(a)(i) (other than as a result

51

of a breach of or inaccuracy in a Parent Fundamental Representation) until the Company Stockholder Indemnified Parties have suffered aggregate Losses by reason of such breaches or inaccuracies in excess of the Deductible (it being understood that if aggregate Losses exceed the Deductible, then the Company Stockholder Indemnified Parties shall be entitled to be indemnified against only the portion of the aggregate Losses that exceed the Deductible). For the avoidance of doubt, the Company Stockholder Indemnified Parties’ right to indemnification under Section 8.3(a)(i) as a result of a breach of or inaccuracy in a Parent Fundamental Representation shall not be subject to the Deductible.

(ii) The maximum amount which the Company Stockholder Indemnified Parties may recover arising out of breaches or inaccuracies described in Section 8.3(a)(i) (other than as a result of a breach of or inaccuracy in a Parent Fundamental Representation) shall be the Cap. For the avoidance of doubt, the Company Stockholder Indemnified Parties’ right to indemnification under Section 8.3(a)(i) as a result of a breach of or inaccuracy in a Parent Fundamental Representation shall not be subject to the Cap.

(iii) Subject to the other limitations contained herein, Parent and the Surviving Corporation shall have the right (but not the obligation) to satisfy all or any portion of any finally determined claim for indemnification under this Section 8.3 with respect to Stock Converting Holders through the issuance to such Stock Converting Holders of a number of additional Parent Series B Preferred Shares equal to the quotient obtained by dividing (A) the applicable Losses to be satisfied with Parent Series B Preferred Shares by (B) the Adjusted Parent Stock Price; provided, that in the event of the consummation of a Parent IPO at any time from and after the Closing Date pursuant to which Parent Series B Preferred Shares are converted into shares of Parent Common Stock, Parent shall be entitled to issue shares of Parent Common Stock in lieu of such Parent Series B Preferred Shares. If the Company’s counsel reasonably determines that the aggregate amount of payments to be made in cash from Parent or the Surviving Corporation to the Stock Converting Holders in satisfaction of any indemnification obligations of Parent or the Surviving Corporation under this Article VIII would cause the Merger to fail to qualify as a reorganization under Section 368 of the Code, the aggregate amount of indemnity payments to be made in cash from Parent or the Surviving Corporation to the Stock Converting Holders shall be decreased by an amount (the amount of such decrease, the “Reduction Amount”) that would not cause the Merger to fail to qualify as a reorganization under Section 368 of the Code and neither Parent nor the Surviving Corporation shall have any further obligation or liability in respect of the payment of such Reduction Amount.

(c) Notwithstanding anything in this Agreement to the contrary, in no event shall Parent and the Surviving Corporation have aggregate liability pursuant to this Section 8.3 in excess of $70,040,000.

8.4. Exclusive Remedy. From and after the Closing Date, the Parent Indemnified Parties’ and the Company Stockholder Indemnified Parties’ sole and exclusive remedy for any claim with respect to the breach of any representation, warranty, covenant or agreement or other express indemnification obligation set forth in this Agreement shall be those remedies set forth in this Article VIII or Section 5.4(c) (for any claim with respect to Taxes); provided, however, that nothing herein shall preclude any party hereto from (a) enforcing its rights to an injunction or specific performance pursuant to Section 9.15, (b) seeking any remedy based

52

upon fraud (with the element of scienter) by any other party hereto (including any such fraud committed by any officer, director or employee of Parent, Merger Sub, the Company Stockholders, the Company or any Affiliate thereof in connection with the transactions contemplated by this Agreement) or (c) seeking any remedy with respect to a breach of any representation, warranty, covenant or agreement or other express indemnification obligation set forth in any agreement entered into in connection with this Agreement, including the Accredited Investor Certification, the Investor Representation Letter and the Letter of Transmittal.

8.5. Additional Provisions Regarding Indemnification.

(a) Notwithstanding any other provision of this Article VIII, the right to indemnification pursuant to this Article VIII is subject to the following limitations; provided, however, that the following limitations described in (i) and (iv) below shall not apply to Losses arising out of or resulting from fraud (with the element of scienter):

(i) in no event will any party to this Agreement be liable under this Agreement (for indemnification) to any other party or other Person for any diminution in value, lost opportunities or punitive damages except where punitive damages are received by a third party from an Indemnified Party in connection with Losses indemnified hereunder;

(ii) the amount of Loss for which any party to this Agreement or other Person may be entitled to seek indemnification under this Agreement will be reduced by the amount of any third-party insurance (and not self-insurance) proceeds or other payment from a third party that is actually received by such party or Person (or its Affiliates) with respect to such Loss (net of any out-of-pocket expenses incurred in obtaining such amounts, any co-payment, retrospective premium adjustment and increased premiums resulting from such Loss as reasonably determined by the Indemnifying Parties and Indemnified Parties (“Reduction Amounts”)); and

(iii) if an Indemnified Party, after having received any indemnification payment pursuant to this Agreement with respect to a Loss, subsequently actually receives any third-party insurance proceeds or other payment from a third party for which it was actually indemnified pursuant to this Article VIII, such Indemnified Party will promptly refund and pay to the Indemnifying Party an amount equal to such insurance proceeds or payment (net of applicable Reduction Amounts).

(b) No Indemnified Party shall be entitled to double recovery for any indemnifiable Losses even though such Losses may have resulted from the breach of more than one of the representations, warranties, agreements, or covenants in this Agreement; provided if an Indemnified Party’s claim under this Article VIII may be properly characterized in multiple ways in accordance with this Article VIII such that such claim may or may not be subject to different limitations depending on such characterization, then such Indemnified Party shall have the right to characterize such claim in a manner that maximizes the recovery and time to assert such claim permitted in accordance with this Article VIII. No Indemnified Party shall be entitled to indemnification under this Agreement in respect of any Losses to the extent such Losses were specifically taken into account in the calculation of, and reduced the Aggregate Closing Parent Shares, including the calculation of the Unpaid Transaction Expenses, Closing Indebtedness, and the Closing Working Capital.

53

(c) The Indemnified Parties shall use such efforts as required by applicable Law to mitigate the amount of any Losses arising from a matter subject to indemnification hereunder; provided, however, that (i) this clause (c) shall not require any Indemnified Party to take any action to recover Losses from any third party; and (ii) the taking of any such action shall not be a condition to indemnification rights hereunder.

(d) All payments (if any) made to an Indemnified Party pursuant to any indemnification, compensation or reimbursement obligations under this Article VIII will be treated as adjustments to the purchase price for Tax purposes and such agreed treatment will govern for purposes of this Agreement, unless otherwise required by Law.

(e) Notwithstanding anything to the contrary in this Agreement, no Indemnified Party shall be entitled to make any claim for recovery for any liability to the extent related to or arising from the amount of or ability of any Indemnified Party to utilize any net operating loss carryforward or other Tax attribute of the Company in any Tax period (or portion thereof) beginning after the Closing Date.

8.6. Indemnification Procedures.

(a) Any party or other Person that has an indemnification obligation under this Article VIII is referred to herein as an “Indemnifying Party” and any party or Person that is entitled to indemnification under this Article VIII is referred to herein as an “Indemnified Party”.

(b) Should any claim or Proceeding by or involving a third party (including any Governmental Authority) not party to this Agreement (or an Affiliate thereof) arise after the Closing Date for which an Indemnifying Party has an indemnification obligation under the terms of this Agreement (a “Third-Party Claim”), the Indemnified Party shall notify the Indemnifying Party in writing (a “Third-Party Claim Notice”) prior to the expiration of the applicable survival date provided in Section 8.1 and within a reasonable time after such Third-Party Claim or Proceeding arises and is known to the Indemnified Party; provided, however, that no delay on the part of the Indemnified Party to provide the Indemnifying Party a Third-Party Claim Notice shall relieve the Indemnifying Party from any obligation hereunder unless (and then solely to the extent) the Indemnifying Party is actually prejudiced as a result thereof.

(c) After receipt of a Third-Party Claim Notice from Parent or the Stockholders’ Representative, as applicable, the other party shall be entitled, at its own cost and expense, to consult with the party who has delivered such Third-Party Claim Notice in any defense of such claim, it being understood that the party who delivered such Third-Party Claim Notice shall have the sole right to control such defense; provided, however, that the Indemnifying Parties and the Indemnified Parties shall cooperate in good faith to implement reasonable arrangements designed to preserve any existing attorney-client privilege; provided, further, that each party shall be entitled to withhold information from the other party if its provision would cause the attorney-client privilege thereof to be waived.

54

(d) No settlement of any Third-Party Claim without the consent (which shall not be unreasonably withheld, conditioned or delayed) of Parent or the Stockholders’ Representative, as applicable, shall be dispositive of whether such Third-Party Claim represented an indemnifiable matter hereunder or determinative of the existence or amount of Losses relating to such matter for which any Indemnified Party shall be entitled to indemnification hereunder. In the event that Parent or the Stockholders’ Representative, as applicable, has consented to any such settlement, however, the applicable Indemnifying Parties shall have no power or authority to object to such Third-Party Claim and the payment of Losses in respect thereof.

(e) Any claim on account of Losses for which indemnification is provided under this Agreement which does not involve a Third-Party Claim shall be asserted by reasonably prompt written notice (a “Notice of Claim”) prior to the expiration of the applicable survival date provided in Section 8.1, stating, in reasonable detail, and to the extent known, the nature and basis of such claim and a good faith, non-binding, preliminary estimate of the aggregate dollar amount of actual Losses that have arisen and are expected to arise as a result of such breach or other matter as set forth on such Notice of Claim, given by the Indemnified Party to the Indemnifying Party; provided, however, that no delay on the part of the Indemnified Party in notifying the Indemnifying Party shall relieve the Indemnifying Party from any obligation hereunder unless (and then solely to the extent) the Indemnifying Party is actually prejudiced as a result thereof.

(f) Upon receipt of a Notice of Claim, the Indemnifying Party and the Indemnified Party shall consult with each other in an attempt to agree upon the matters set forth in the Notice of Claim and reach a written agreement with respect to such matters (a “Claim Settlement Agreement”). If the Indemnifying Party and the Indemnified Party fail to agree upon the matters contained in such Notice of Claim within thirty (30) days after the date the Notice of Claim is delivered to the Indemnified Party, then, at the request of any party, the Indemnifying Party and the Indemnified Party shall meet in an attempt to resolve the objection described in such Notice of Claim and reach a Claim Settlement Agreement. If the Indemnifying Party and the Indemnified Party enter into a Claim Settlement Agreement, the objections contained in such Notice of Claim shall be deemed to be as resolved as provided therein. If the Indemnifying Party and the Indemnified Party are unable to resolve the objection described in such Notice of Claim within sixty (60) days after delivery by the Indemnified Party of such Notice of Claim, then either party may submit the objections contained in such Notice of Claim for resolution in a Proceeding commenced as contemplated by Section 9.12.

8.7. Calculation of Loss Amount. For purposes of determining whether any representation or warranty in this Agreement has been breached and the amount of any Losses with respect to any claim for indemnification under Section 8.2 or Section 8.3, any qualifiers as to materiality (including Material Adverse Effect or similar terms) contained in an applicable representation and warranty shall be deemed to be deleted and shall be given no force or effect.

8.8. Indemnification Holdback Amount.

(a) The Indemnification Holdback Amount shall be withheld from the consideration otherwise payable to each Company Stockholder at Closing in accordance with Section 1.8 and retained by Parent to be used solely for the satisfaction of indemnification obligations of the Company Stockholders under Article VIII. The Company Stockholders shall not receive interest on the Indemnification Holdback Amount. Neither the Indemnification

55

Holdback Amount (including any portion thereof) nor any beneficial interest therein may be pledged, subjected to any Encumbrance, sold, assigned or transferred by any Company Stockholder, or be taken or reached by any legal or equitable process in satisfaction of any debt or other liability of any Company Stockholder, in each case prior to the distribution of the Indemnification Holdback Amount to any Company Stockholder in accordance with this Section 8.8. Any Parent Series B Preferred Shares withheld from the Stock Converting Holders in respect of the Indemnification Holdback Amount in accordance with Section 1.8 shall constitute issued and outstanding stock of Parent, which Parent shall hold in escrow on behalf of the Company Stockholders pending release under Section 8.8(c). The Stock Converting Holders shall be entitled to exercise voting rights and shall be entitled to receive any dividends with respect to such shares until such time, if any, as such shares are cancelled by Parent as provided in this Article VIII.

(b) Parent shall be entitled to permanently retain from the Indemnification Holdback Amount in respect of finally determined Losses (i) with respect to each Cash Converting Holder, an amount of cash equal to the Losses which the Parent Indemnified Parties are entitled to recover from such Cash Converting Holder (in accordance with such Cash Converting Holder’s Pro Rata Share) and (ii) with respect to each Stock Converting Holder, subject to Section 8.2(d) and any Voluntary Cash Payments made pursuant thereto, a number of Parent Series B Preferred Shares equal to the quotient obtained by dividing (A) the Losses which the Parent Indemnified Parties are entitled to recover from such Stock Converting Holder (in accordance with such Stock Converting Holder’s Pro Rata Share) by (B) the Adjusted Parent Stock Price. The parties hereto acknowledge that the Adjusted Parent Stock Price only reflects an agreed-upon amount as to the value of Parent Series B Preferred Shares solely for the limited purpose of satisfying any Losses under this Article VIII and is not intended to be, nor is it, deemed to constitute the fair market value of Parent Series B Preferred Shares at any given time.

9.4. References. The titles, captions or headings of the Articles and Sections herein are inserted for convenience of reference only and are not intended to be a part of or to affect the meaning or interpretation of this Agreement. All references to “days” or “months” shall be deemed references to calendar days or months. All references to “$” or “dollars” shall be deemed references to United States dollars. Any dollar amounts or thresholds set forth herein shall not be used as a determinative benchmark for establishing what is or is not “material” or a “Material Adverse Effect” (or words of similar import) under this Agreement Unless the context otherwise requires, any reference to an “Article”, “Section,” “Exhibit,” or “Schedule” shall be deemed to refer to an article of this Agreement, Section of this Agreement, exhibit to this Agreement or a schedule to this Agreement, as applicable. Any reference to any federal, state, county, local or foreign statute or Law shall be deemed also to refer to all rules and regulations promulgated thereunder, unless the context requires otherwise. For all purposes of and under this Agreement, (a) the words “include”, “includes” and “including” shall be deemed to be immediately followed by the words “without limitation”; (b) words (including defined terms) in the singular shall be deemed to include the plural and vice versa; (c) words of one gender shall be deemed to include the other genders as the context requires; (d) “or” is not exclusive; (e) the word “will” shall

71

be construed to have the same meaning and effect as the word “shall”; (f) unless otherwise stated, any reference herein to any Person shall be construed to include such Person’s successors and assigns; and (g) the terms “hereof,” “herein,” “hereto,” “herewith”, “hereunder” and any other words of similar import shall, unless otherwise stated, be construed to refer to this Agreement as a whole (including the exhibits and schedules hereto) and not to any particular term or provision of this Agreement, unless otherwise specified.

9.5. Entire Agreement. This Agreement, including the Exhibits hereto, the Company Disclosure Schedule, the Parent Disclosure Schedule and the other agreements, documents and written understandings referred to herein or otherwise entered into or delivered by the parties hereto pursuant to this Agreement (including the Letters of Transmittal and the Investor Representation Letters), constitute the entire agreement and understanding of the parties hereto with respect to the subject matter hereof and supersede all other prior covenants, agreements (including any letters of intent between the parties), undertakings, obligations, promises, arrangements, communications, representations and warranties, whether oral or written, by any party hereto with respect to the subject matter hereof.

9.6. Assignment. No party may assign, delegate or otherwise transfer any of its rights or obligations under this Agreement without the consent of each other party hereto.

9.8. Waiver. Except where a specific period for action or inaction is provided herein, neither the failure nor any delay on the part of any party in exercising any right, power or privilege under this Agreement or the documents referred to in this Agreement shall operate as a waiver thereof, nor shall any waiver on the part of any party of any such right, power or privilege, nor any single or partial exercise of any such right, power or privilege, preclude any other or further exercise thereof or the exercise of any other such right, power or privilege. The failure of a party to exercise any right conferred herein within the time required shall cause such right to terminate with respect to the transaction or circumstances giving rise to such right, but not to any such right arising as a result of any other transactions or circumstances.

9.9. Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced as a result of any rule of Law or public policy, all other terms and other provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated by this Agreement is not affected in any manner materially adverse to any party. 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 as closely as possible in an acceptable manner to the end that the transactions contemplated by this Agreement are fulfilled to the greatest extent possible.

72

9.10. Burden and Benefit. This Agreement shall be binding upon and shall inure to the benefit of, the parties hereto and their respective successors and permitted assigns. This Agreement and all of its conditions and provisions are for the sole and exclusive benefit of the parties hereto and their respective successors and permitted assigns, and nothing in this Agreement, express or implied, is intended to confer upon any Person other than the parties hereto any rights or remedies of any nature whatsoever under or by reason of this Agreement or any provision hereof; provided, however, that the provisions of Section 5.5 are intended to be for the benefit of, and enforceable by, the Company Indemnified Parties.

9.11. Governing Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of Delaware, without giving effect to principles of conflicts of laws that would require the application of the laws of any other jurisdiction.

9.12. Consent to Jurisdiction. The parties hereto agree that any Proceeding seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the transactions contemplated hereby shall be brought in any federal or state court located in the State of Delaware, and each of the parties hereby irrevocably consents to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such Proceeding and irrevocably waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to the laying of the venue of any such Proceeding in any such court or that any such Proceeding brought in any such court has been brought in an inconvenient forum. Process in any such Proceeding may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing, each party agrees that service of process on such party as provided in Section 9.2 shall be deemed effective service of process on such party.

9.13. Waiver of Trial by Jury. EACH PARTY TO THIS AGREEMENT ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE IT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE AGREEMENTS DELIVERED IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE EITHER OF SUCH WAIVERS, (B) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVERS, (C) IT MAKES SUCH WAIVERS VOLUNTARILY, AND (D) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.13.

9.14. Limitations on Damages. Notwithstanding anything to the contrary in this Agreement, in no event shall any party be liable for punitive damages to the other party (except for punitive damages that are payable to third parties).

73

9.15. Specific Performance. The parties hereto agree that irreparable damage would occur if any provision of this Agreement were not performed in accordance with the terms hereof or were otherwise breached and that, irrespective of any other rights or remedies that may be available to the parties as provided herein or otherwise, the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof in any federal or state court located in the State of Delaware. Each of the parties hereto agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief on the basis that the other parties hereto have an adequate remedy at law or an award of specific performance is not an appropriate remedy for any reason at law or equity. The parties hereto 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 this Section 9.15 shall not be required to provide any bond or other security in connection with any such order or injunction.

9.16. Cumulative Remedies. Except as otherwise expressly set forth in this Agreement, including in Section 8.4, all rights and remedies of any party hereto are cumulative of each other and of every other right or remedy such party may otherwise have at Law or in equity, and the exercise of one or more rights or remedies shall not prejudice or impair the concurrent or subsequent exercise of other rights or remedies.

9.17. Expenses. Except as otherwise expressly set forth in this Agreement, all costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such expenses.

9.18. Representation by Counsel. Each party hereto represents and agrees with each other that it has been represented by or had the opportunity to be represented by, independent counsel of its own choosing, and that it has had the full right and opportunity to consult with its respective attorney(s), that to the extent, if any, that it desired, it availed itself of this right and opportunity, that it or its authorized officers (as the case may be) have carefully read and fully understand this Agreement in its entirety and have had it fully explained to them by such party’s respective counsel, that each is fully aware of the contents thereof and its meaning, intent and legal effect, and that it or its authorized officer (as the case may be) is competent to execute this Agreement and has executed this Agreement free from coercion, duress or undue influence.

9.19. Execution and Counterparts. This Agreement may be executed in one or more counterparts, each of which when executed shall be deemed an original and all of which together shall constitute one and the same instrument. The parties agree that this Agreement shall be legally binding upon the electronic transmission, including by facsimile or email, by each party of a signed signature page to this Agreement to the other party.

9.20. Stockholders’ Representative.

(a) Appointment. By executing this Agreement, the Company (and, upon execution of the Written Consent or Letter of Transmittal by a Company Stockholder, such Company Stockholder) shall be deemed to have constituted and appointed, effective from and after the Effective Time, Fortis Advisors LLC as exclusive agent and attorney-in-fact for and on behalf of each Company Stockholder to act as the Stockholders’ Representative under this Agreement, including in respect of the following matters:

(i) giving and receiving any notice or instruction permitted or required to be given to or received by any Company Stockholder under this Agreement;

74

(ii) coordinating the common defense of all indemnity claims against the Company Stockholders by any Parent Indemnified Party pursuant to this Agreement (a “Parent Indemnity Claim”),

(iii) consenting to, compromising or settling all Parent Indemnity Claims,

(iv) conducting negotiations with Parent and its Representatives regarding such Parent Indemnity Claims,

(v) dealing with Parent under this Agreement with respect to all matters arising under this Agreement, and

(vi) engaging counsel, accountants or other Stockholders’ Representatives in connection with the foregoing matters.

(b) Authorization. By each Company Stockholder’s execution of the Written Consent or Letter of Transmittal, each such Company Stockholder shall authorize the Stockholders’ Representative, on such Company Stockholder’s behalf, to:

(i) receive all notices or documents given or to be given to any of the Company Stockholders by Parent or the Surviving Corporation pursuant hereto or in connection herewith and to receive and accept service of legal process in connection with any suit or proceeding arising under this Agreement;

(ii) engage counsel, and such accountants and other advisors for any of the Company Stockholders and incur such other expenses on behalf of any of the Company Stockholders in connection with this Agreement and the transactions contemplated hereby or thereby as the Stockholders’ Representative may in its sole discretion deem appropriate;

(iii) take such action on behalf of any of the Company Stockholders as the Stockholders’ Representative may in its sole discretion deem appropriate in respect of: (A) taking such other action as the Stockholders’ Representative is authorized to take under this Agreement and the Stockholders’ Representative Engagement Agreement; (B) receiving all documents or certificates and making all determinations, on behalf of any of the Company Stockholders, required under this Agreement; and (C) all such action as may be necessary after the Closing Date to carry out any of the transactions contemplated by this Agreement, including, the defense and/or settlement of any claims for which indemnification is sought pursuant to Article VIII and any waiver of any obligation of Parent or the Surviving Corporation. Notwithstanding the foregoing, the Stockholders’ Representative shall have no obligation to act on behalf of the Company Stockholders, except as expressly provided herein and in the Stockholders’ Representative Engagement Agreement, and for purposes of clarity, there are no obligations of the Stockholders’ Representative in any ancillary agreement, schedule, exhibit or the Company Disclosure Schedule.

75

(c) Decisions. The powers, immunities and rights to indemnification granted to the Stockholders’ Representative Group hereunder: (i) are coupled with an interest and shall be irrevocable and survive the death, incompetence, bankruptcy or liquidation of any Company Stockholder and shall be binding on any successor thereto, and (ii) shall survive the delivery of an assignment by any Company Stockholder of the whole or any fraction of his, her or its interest in the Indemnification Holdback Amount. All actions, decisions and instructions of the Stockholders’ Representative shall be conclusive and binding upon all of the Company Stockholders and such Company Stockholder’s successors as if expressly confirmed and ratified in writing by such Company Stockholder and no Company Stockholder shall have any claim or cause of action against the Stockholders’ Representative, and the Stockholders’ Representative shall have no liability to any Company Stockholder, for any action taken, decision made or instruction given by the Stockholders’ Representative in connection with this Agreement or the Stockholders’ Representative Engagement Agreement, except in the case of its own gross negligence or willful misconduct.

(d) Limitation of Liability. Certain Company Stockholders have entered into an engagement agreement (the “Stockholders’ Representative Engagement Agreement”) with the Stockholders’ Representative to provide direction to the Stockholders’ Representative in connection with its services under this Agreement and the Stockholders’ Representative Engagement Agreement (such Company Stockholders, including their individual representatives, collectively hereinafter referred to as the “Advisory Group”). Neither the Stockholders’ Representative nor its members, managers, directors, officers, contractors, agents and employees nor any member of the Advisory Group (collectively, the “Stockholders’ Representative Group”), shall be liable to any Company Stockholder for any action or failure to act in connection with the acceptance or administration of the Stockholders’ Representative’s responsibilities hereunder or under the Stockholders’ Representative Engagement Agreement, unless and only to the extent such action or failure to act constitutes gross negligence, fraud, or willful misconduct.

(e) Indemnification. The Company Stockholders shall indemnify, defend and hold harmless the Stockholders’ Representative Group from and against any and all losses, claims, damages, liabilities, fees, costs, expenses (including fees, disbursements and costs of counsel and other skilled professionals and in connection with seeking recovery from insurers), judgments, fines or amounts paid in settlement (collectively, the “Stockholders’ Representative Expenses”) incurred without gross negligence or willful misconduct on the part of the Stockholders’ Representative and arising out of or in connection with the acceptance or administration of its duties hereunder or under the Stockholders’ Representative Engagement Agreement. Such Stockholders’ Representative Expenses may be recovered first, from the Expense Fund, second, from any distribution of the Indemnification Holdback Amount otherwise distributable to the Company Stockholders at the time of distribution, and third, directly from the Company Stockholders. The Company Stockholders acknowledge that the Stockholders’ Representative shall not be required to expend or risk its own funds or otherwise incur any financial liability in the exercise or performance of any of its powers, rights, duties or privileges or pursuant to this Agreement or the transactions contemplated hereby. Furthermore, the Stockholders’ Representative shall not be required to take any action unless the Stockholders’ Representative has been provided with funds, security or indemnities which, in its determination, are sufficient to protect the Stockholders’ Representative against the costs, expenses and liabilities which may be incurred by the Stockholders’ Representative in performing such actions.

76

(f) Reliance. Parent, Merger Sub and the Surviving Corporation shall not be obliged to inquire into the authority of the Stockholders’ Representative, and Parent, Merger Sub and the Surviving Corporation shall be fully protected in dealing with the Stockholders’ Representative in good faith. The Stockholders’ Representative shall be entitled to: (i) rely upon the Consideration Schedule, (ii) rely upon any signature believed by it to be genuine, and (iii) reasonably assume that a signatory has proper authorization to sign on behalf of the applicable Company Stockholder or other party.

(g) Successor Stockholders’ Representative. If the Stockholders’ Representative shall die, become disabled, resign or otherwise be unable to fulfill its responsibilities hereunder, the Company Stockholders who in the aggregate held at least a majority of the Company Capital Stock immediately prior to the Effective Time shall appoint a new Stockholders’ Representative as soon as reasonably practicable by written consent by sending notice and a copy of the duly executed written consent appointing such new Stockholders’ Representative to Parent and the Surviving Corporation. Such appointment will be effective upon the later of the date indicated in the consent or the date such consent is received by Parent and the Surviving Corporation. Company Stockholders who in the aggregate held at least a majority of the Company Capital Stock immediately prior to the Effective Time shall have the right at any time to remove the then-acting Stockholders’ Representative and to appoint a successor Stockholders’ Representative; provided, however, that neither such removal of the then acting Stockholders’ Representative nor such appointment of a successor Stockholders’ Representative shall be effective until the delivery to Parent and Surviving Corporation of executed counterparts of a writing signed by each such Company Stockholder with respect to such removal and appointment, together with an acknowledgment signed by the successor Stockholders’ Representative appointed in such writing that it, he or she accepts the responsibility of successor Stockholders’ Representative and agrees to perform and be bound by all of the provisions of this Agreement applicable to the Stockholders’ Representative. The immunities and rights to indemnification shall survive the resignation or removal of the Stockholders’ Representative or any member of the Advisory Group and the Closing and/or any termination of this Agreement. Each successor Stockholders’ Representative shall have all of the power, authority, rights, privileges and obligations conferred by this Agreement upon the original Stockholders’ Representative, and the term “Stockholders’ Representative” as used herein shall be deemed to include any interim or successor Stockholders’ Representative.

(h) Expense Fund. Upon the Closing, the Company shall wire to the Stockholders’ Representative $[***] (the “Expense Fund Amount”). The Expense Fund Amount shall be held by the Stockholders’ Representative in a segregated client account and shall be used (i) for the purposes of paying directly or reimbursing the Stockholders’ Representative for any Stockholders’ Representative Expenses incurred pursuant to this Agreement or any Stockholders’ Representative Engagement Agreement, or (ii) as otherwise determined by the Advisory Group (the “Expense Fund”). The Stockholders’ Representative is not providing any investment supervision, recommendations or advice and shall have no responsibility or liability for any loss of principal of the Expense Fund other than as a result of its gross negligence or willful misconduct. The Stockholders’ Representative is not acting as a withholding agent or in any similar capacity in connection with the Expense Fund and has no tax reporting or income distribution obligations. The Company Stockholders will not receive any interest on the Expense Fund and assign to the Stockholders’ Representative any such interest. Subject to Advisory Group approval, the

77

Stockholders’ Representative may contribute funds to the Expense Fund from any consideration otherwise distributable to the Company Stockholders. As soon as reasonably determined by the Stockholders’ Representative that the Expense Fund is no longer required to be withheld, the Stockholders’ Representative shall distribute the remaining Expense Fund (if any) to Parent for further distribution to the Company Stockholders.

9.21 Waiver of Conflicts; Privilege.

(a) Each of the parties acknowledges and agrees that ▇▇▇▇▇▇▇ Procter LLP (“▇▇▇▇▇▇▇”) has acted as counsel to the Company and the Stockholders’ Representative in connection with the negotiation of this Agreement and consummation of the transactions contemplated hereby.

(b) Parent hereby consents and agrees to, and agrees to cause Surviving Corporation to consent and agree to, ▇▇▇▇▇▇▇ representing the Stockholders’ Representative after the Closing, including with respect to disputes in which the interests of the Stockholders’ Representative may be directly adverse to Parent and its Subsidiaries (including the Surviving Corporation), and even though ▇▇▇▇▇▇▇ may have represented the Company in a matter substantially related to any such dispute, or may be handling ongoing matters for the Company. Parent further consents and agrees to, and agrees to cause the Surviving Corporation to consent and agree to, the communication by ▇▇▇▇▇▇▇ to the Stockholders’ Representative in connection with any such representation of any fact known to ▇▇▇▇▇▇▇ arising by reason of ▇▇▇▇▇▇▇’▇ prior representation of the Company.

(c) In connection with the foregoing, Parent hereby irrevocably waives and agrees not to assert, and agrees to cause the Surviving Corporation to irrevocably waive and not to assert, any conflict of interest arising from or in connection with (i) ▇▇▇▇▇▇▇’▇ prior representation of the Company and (ii) ▇▇▇▇▇▇▇’▇ representation of the Stockholders’ Representative prior to and after the Closing.

(d) Parent further agrees, on behalf of itself and, after the Closing, on behalf of the Surviving Corporation, that all communications in any form or format whatsoever between or among any of ▇▇▇▇▇▇▇, on the one hand, and the Company, the Company’s Subsidiaries, the Stockholders’ Representative and/or any Company Stockholder, or any of their respective directors, officers, employees or other Representatives, on the other hand, that relate in any way to the negotiation, documentation and consummation of the transactions contemplated by this Agreement or any dispute arising under this Agreement (collectively, the “Deal Communications”) shall be deemed to be retained and owned collectively by the Company Stockholders, shall be controlled by the Stockholders’ Representative on behalf of the Company Stockholders and shall not pass to or be claimed by Parent or the Surviving Corporation. All Deal Communications that are attorney-client privileged (the “Privileged Deal Communications”) shall remain privileged after the Closing and the privilege and the expectation of client confidence relating thereto shall belong solely to the Stockholders’ Representative and the Company Stockholders, shall be controlled by the Stockholders’ Representative on behalf of the Company Stockholders and shall not pass to or be claimed by Parent or the Surviving Corporation.

78

(e) Notwithstanding the foregoing, in the event that a dispute arises between Parent or the Surviving Corporation, on the one hand, and a third party other than the Stockholders’ Representative, on the other hand, Parent or the Surviving Corporation may assert the attorney-client privilege to prevent the disclosure of the Privileged Deal Communications to such third party; provided, however, that neither Parent nor the Surviving Corporation may knowingly waive such privilege without the prior written consent of the Stockholders’ Representative (which such consent shall not be unreasonably withheld, conditioned or delayed); provided, further, that if Parent or the Surviving Corporation discloses any Privileged Deal Communications without the prior written consent of the Stockholders’ Representative, then Parent and the Surviving Corporation shall use their reasonable best efforts to obtain a protective order with respect to, and to recover, such disclosed Privileged Deal Communications. In the event that Parent or the Surviving Corporation is legally required by applicable Law, an Order or otherwise to access or obtain a copy of all or a portion of the Privileged Deal Communications after the Closing, Parent shall promptly (and, in any event, within five (5) Business Days) notify the Stockholders’ Representative (if after Closing) in writing (including by making specific reference to this Section 9.21(e)) so that the Stockholders’ Representative can seek a protective order and Parent agrees to use all commercially reasonable efforts, at the sole cost and expense of the Stockholders’ Representative, reasonably requested by the Stockholders’ Representative to assist therewith.

(f) To the extent that files or other materials maintained by ▇▇▇▇▇▇▇ constitute property of its clients, only the Stockholders’ Representative shall hold such property rights and ▇▇▇▇▇▇▇ shall have no duty to reveal or disclose any such files or other materials or any Privileged Deal Communications by reason of any attorney-client relationship between ▇▇▇▇▇▇▇, on the one hand, and Parent or the Surviving Corporation, on the other hand.

(g) Parent agrees that it will not, and that it will cause the Surviving Corporation not to, access or use the Privileged Deal Communications, including by way of review of any electronic data, communications or other information or seek to obtain the Deal Communications from ▇▇▇▇▇▇▇.
