The right of any Company Holder to receive a portion of the Merger Consideration shall be subject to and reduced by the amount of any Tax withholding that is required under applicable Law.

Section 2.8 Payment Procedures.

(a) Closing Allocation. Subject to Section 2.8(f), at, or prior to, the Closing, the Buyer will deposit, or cause to be deposited, (i) with the Paying Agent such portion of the Closing Cash Payment payable to the Company Holders other than the Company Award Holders and less the aggregate Note Obligations, and pay to the Surviving Corporation such aggregate Note Obligations and such portion of the Closing Cash Payment payable to the Company Award Holders to be distributed by the Surviving Corporation through the payroll process of the Surviving Corporation, subject to applicable withholding, (ii) with the Escrow Agent, the Escrow Amount and (iii) with the Shareholders’ Representative, the Shareholders’ Representative Fund Amount. At, or prior to the Closing, the Buyer shall deliver a letter of instruction to the Buyer’s transfer agent to issue the Closing Stock Payment in the names and amounts set forth on the Allocation Schedule.

(b) Surrender and Payment Procedures. As soon as reasonably practicable after the date hereof (but in no event later than one (1) Business Day after the date hereof), Buyer will instruct the Paying Agent to mail (as soon as reasonably practicable following delivery by the Company of the information and documents the Paying Agent reasonably requests to effect such mailing) to each Company Holder (other than the Company Award Holders, the procedure for which is described in clause (f) below), (i) a letter of transmittal, in the form set forth in Exhibit E, which will specify that delivery will be effected, and risk of loss and title to any Certificate(s) formerly representing Company Capital Stock will pass, only upon receipt of such Certificate(s) by the Paying Agent (the “Letter of Transmittal”), and (ii) instructions for use in effecting the surrender of Certificate(s) formerly representing all the Company Capital Stock held by such

28

Company Holder in exchange for the Merger Consideration payable to such Company Holder. Such payment is conditioned upon (i) the due execution and delivery of such Letter of Transmittal, (ii) a properly executed Form W-9 or Form W-8BEN (or W-8BEN-E) or other applicable Form W-8, if applicable, from such holder in form and substance acceptable to the Paying Agent and (iii) any other documents as may be reasonably requested by the Paying Agent or the Buyer’s transfer agent. As soon as reasonably practicable after the Effective Time after receipt by the Paying Agent of Certificate(s), properly endorsed or otherwise in proper form for transfer, formerly representing all the Company Capital Stock held by any Company Holder for cancellation, together with such duly executed Letter of Transmittal and any other documents as may be reasonably requested by the Paying Agent (but in no event more than five (5) Business Days after the receipt of such materials), the Paying Agent will, in exchange therefor and in reliance on the representations and warranties herein and therein, deliver to such Company Holder the cash portion of the Per Share Closing Consideration and the Transfer Agent shall promptly provide a statement reflecting the book entry position of the stock portion of the Per Share Closing Consideration issued to such Company Holder.

(c) Alternative Payee and Taxes. If payment of any portion of the applicable Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificate(s) are registered, it will be a condition of payment that the Person requesting such payment (A) will have paid any Taxes required by reason of the payment of those amounts to a Person other than the registered holder of the certificate(s) surrendered, and will have established to the satisfaction of the Buyer that such Taxes have been paid, or (B) will have established to the satisfaction of the Buyer that such Taxes are not applicable. From and after the Effective Time, until surrendered as contemplated by this Section 2.8, each certificate formerly representing Company Capital Stock will be deemed to represent for all purposes only the right to receive the applicable consideration set forth in this Article 2, if any, in respect of such interests formerly represented thereby in accordance with the terms hereof and in the manner provided herein.

(d) Termination of Fund; No Liability. At any time following twelve months after the Effective Time, the Buyer will be entitled to require the Paying Agent to deliver to it any funds (including, without limitation, any earnings received with respect thereto) that had been made available to the Paying Agent and that have not been disbursed to the Company Holders and thereafter such holders will be entitled to look only to the Buyer (subject to abandoned property, escheat or other similar Legal Requirements) and only as general creditors thereof with respect to such holder’s applicable payment, upon and subject to delivery of the duly executed applicable Letter of Transmittal, as applicable, and, with respect to any Company Holder, upon due surrender of their certificates formerly representing such interests, without any interest thereon. Notwithstanding the foregoing, none of the Buyer, the Surviving Corporation or the Paying Agent will be liable to any Company Holder for any amounts delivered to a public official pursuant to any applicable abandoned property, escheat or similar Legal Requirement.

(e) Lost, Stolen or Destroyed Certificates. In the event any Certificate(s) has been lost, stolen or destroyed, upon the making and delivery of an affidavit of that fact by the holder thereof in form reasonably satisfactory to the Buyer and the Paying Agent, the Buyer or Paying Agent will pay such holder the payment to which such holder is entitled, as provided in this Article 2; provided, however, that the Buyer may, in its sole discretion and as a condition precedent to issuing such payment, require the owner of such lost, stolen or destroyed Certificate(s) to deliver an

29

agreement of indemnification in form reasonably satisfactory to the Buyer and a bond in such sum as the Buyer may reasonably direct as indemnity, not to exceed the amount of the Company Holder’s Merger Consideration, against any claim that may be made against the Buyer or the Surviving Corporation with respect to the certificate(s) alleged to have been lost, stolen or destroyed.

(f) Company Options and Company RSU Awards. As soon as reasonably practicable after the date hereof (but in no event later than five (5) Business Days after the date hereof), the Company shall distribute to each Company Award Holder an Equity Award Cancellation Agreement in substantially the form attached hereto as Exhibit F (an “Equity Award Cancellation Agreement”). Subject to Buyer’s receipt of a duly-executed Equity Award Cancellation Agreement from the applicable Company Award Holder, the Buyer shall, or shall cause the Surviving Corporation to (i) pay each such Company Award Holder, as promptly as practicable through its payroll (and in any event no later than the next payroll period of the Buyer or the Surviving Corporation after the Closing Date), such Company Award Holder’s share of the cash portion of the Closing Merger Consideration in accordance with the Allocation Schedule, and (ii) cause the Buyer’s transfer agent to deliver a statement reflecting such Company Award Holder’s shares of Buyer Common Stock, if any, in book entry, which amounts shall be paid less any applicable tax withholding required by applicable Law. For the avoidance of doubt, all applicable Tax withholding for the Per Share Closing Consideration payable to a Company Award Holder (including any portion paid in the form of Buyer Common Stock, if any) shall be deducted from the portion of such Per Share Closing Consideration payable in cash to such Company Award Holder. The Company shall use its reasonable best efforts to obtain executed Equity Award Cancellation Agreements from all Company Award Holders prior to the Closing Date.

(g) Optionholder Notes. Each holder of Company Options as of the date of this Agreement who elects to exercise his or her Company Options prior the Effective Time may elect to execute a promissory note in the form attached hereto as Exhibit G (the “Optionholder Note”) for the purpose of paying the applicable exercise price and any applicable withholding Taxes payable by such holder with respect to the exercise of such Company Options (each holder who so elects is referred to herein as an “Electing Optionholder”). The amount of each Optionholder Note shall be referenced as the “Note Obligation” and reflected on the Allocation Spreadsheet opposite the name of each Electing Optionholder. The Note Obligations, plus any interest due at the time of repayment of the Optionholder Notes, shall be repaid by each Electing Optionholder automatically by offsetting the Note Obligation against the portion of the Closing Consideration to be paid in cash to such Electing Optionholder.

Section 2.9 Shareholders’ Representative.

(a) By voting in favor of or consenting to the Merger or by surrendering or delivering to the Paying Agent or the Company (or its designee payroll service provider), as applicable, an executed Letter of Transmittal to the Paying Agent, in exchange for the consideration to be paid in accordance with this Agreement, each Company Holder irrevocably approves the depositing of the funds held in the Shareholders’ Representative Fund and the constitution and appointment of, and hereby irrevocably constitutes and appoints Shareholder Representative Services LLC as the sole, exclusive, true and lawful agent, representative and attorney-in-fact of all Company Holders and each of them (the “Shareholders’ Representative”) with respect to any and all matters relating

30

to, arising out of, or in connection with, this Agreement, the Paying Agent Agreement or any agreements ancillary hereto, including for purposes of taking any action or omitting to take any action on behalf of each Company Holder hereunder to:

(i) execute and deliver all amendments, waivers, ancillary agreements, certificates and documents that the Shareholders’ Representative deems necessary or appropriate in connection with the consummation of the transactions contemplated by this Agreement or the Paying Agent Agreement, or in connection with any of the matters set forth in clauses (ii) through (xi) of this Section 2.9(a);

(iii) receive funds, make payments of funds and give receipts for funds;

(iv) do or refrain from doing any further act or deed on behalf of the Company Holders that the Shareholders’ Representative deems necessary or appropriate in its discretion relating to the subject matter of this Agreement as fully and completely as the Company Holders could do if personally present;

(v) administer the defense or settlement of any disputes regarding the Closing Cash Payment adjustment pursuant to Section 2.12 and agreeing to or negotiating the Final Closing Statement and Final Closing Cash Payment;

(vi) administer the defense or settlement of any disputes regarding any Contingent Payments pursuant to Section 2.13;

(vii) contest any claims for indemnification pursuant to Section 8.1, to deliver any Claim Dispute Notice pursuant to Section 8.4, and to administer the defense or settlement of any such claims for indemnification, and of any disputes with respect thereto;

(viii) give any written direction to the Paying Agent;

(ix) give or receive notices to be given or received by the Company Holders under this Agreement, or the Paying Agent Agreement (except to the extent that this Agreement, or the Paying Agent Agreement expressly contemplates that any such notice shall be given or received by each Company Holder individually);

(x) receive service of process in connection with any claims under this Agreement or the Paying Agent Agreement; and

(xi) take any other action that, pursuant to the express terms hereof, is to be (or which may be taken by) the Shareholders’ Representative.

31

All actions, notices, communications and determinations by or on behalf of the Company Holders shall be given or made by the Shareholders’ Representative and all such actions, notices, communications and determinations by the Shareholders’ Representative shall conclusively be deemed to have been authorized by, and shall be binding upon, any of and all Company Holders, and no Company Holder shall have the right to object, dissent, protest or otherwise contest the same. Without limiting the rights and obligations of the Company, Buyer and Merger Sub under this Agreement, the Shareholders’ Representative shall be entitled to: (i) rely upon the Estimated Closing Statement, Allocation Schedule, the Transaction Expense Schedule, and the CoC Payment 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 Holder.

(b) The Shareholders’ Representative may resign at any time. If the Shareholders’ Representative resigns, dies or becomes legally incapacitated, then a majority of the Company Holders, based on their respective Pro Rata Percentages, shall promptly designate in writing to Buyer a single Person to fill the Shareholders’ Representative vacancy as the successor Shareholders’ Representative hereunder. If at any time there shall not be a Shareholders’ Representative or the Company Holders fail to designate a successor Shareholders’ Representative, then Buyer may have a court of competent jurisdiction appoint a Shareholders’ Representative hereunder. A majority of the Company Holders, based on their respective Pro Rata Percentages, may also replace the Person serving as the Shareholders’ Representative from time to time and for any reason upon at least ten (10) days’ prior written notice to Buyer.

(c) The Shareholders’ Representative shall act for the Company Holders on all of the matters set forth in this Agreement in the manner the Shareholders’ Representative reasonably believes to be in the best interest of the Company Holders. The Shareholders’ Representative is authorized to act on behalf of the Company Holders notwithstanding any dispute or disagreement among the Company Holders. In taking any actions as Shareholders’ Representative, the Shareholders’ Representative may rely conclusively, without any further inquiry or investigation, upon any certification or confirmation, oral or written, given by any Person the Shareholders’ Representative reasonably believes to be authorized thereunto. The Shareholders’ Representative undertakes to perform such duties and only such duties as are specifically set forth in this Agreement and no implied covenants or obligations shall be read into this Agreement against the Shareholders’ Representative. The Shareholders’ Representative will incur no liability of any kind with respect to any action or omission by the Shareholders’ Representative in connection with the Shareholders’ Representative’s services pursuant to this Agreement and any agreements ancillary hereto, except in the event of liability directly resulting from the Shareholders’ Representative’s gross negligence or willful misconduct. The Shareholders’ Representative shall not be liable for any action or omission pursuant to the advice of counsel. The Company Holders will indemnify, defend and hold harmless the Shareholders’ Representative from and against any and all losses, liabilities, damages, claims, penalties, fines, forfeitures, actions, fees, costs and expenses (including the fees and expenses of counsel and experts and their staffs and all expense of document location, duplication and shipment) (collectively, “Representative Losses”) arising out of or in connection with the Shareholders’ Representative’s execution and performance of this Agreement and any agreements ancillary hereto, in each case as such Representative Loss is suffered or incurred; provided, that in the event that any such Representative Loss is finally adjudicated to have been directly caused by the gross negligence or willful misconduct of the

32

Shareholders’ Representative, the Shareholders’ Representative will reimburse the Company Holders the amount of such indemnified Representative Loss to the extent attributable to such gross negligence or willful misconduct. If not paid directly to the Shareholders’ Representative by the Company Holders, any such Representative Losses may be recovered by the Shareholders’ Representative from (i) the funds in the Shareholders’ Representative Fund and (ii) the Escrow Fund, any Development Milestone Payment or any Royalty Payment, in each case only at or after such time as remaining amounts would otherwise be distributable to the Company Holders; provided, that while this section allows the Shareholders’ Representative to be paid from the aforementioned sources of funds, this does not relieve the Company Holders from their obligation to promptly pay such Representative Losses as they are suffered or incurred, nor does it prevent the Shareholders’ Representative from seeking any remedies available to it at law or otherwise. In no event will the Shareholders’ Representative be required to advance its own funds on behalf of the Company Holders or otherwise. Notwithstanding anything in this Agreement to the contrary, any restrictions or limitations on liability or indemnification obligations of, or provisions limiting the recourse against non-parties otherwise applicable to, the Company Holders set forth elsewhere in this Agreement are not intended to be applicable to the indemnities provided to the Shareholders’ Representative under this section. The foregoing indemnities will survive the Closing, the resignation or removal of the Shareholders’ Representative or the termination of this Agreement. Except for this Agreement and the Shareholders’ Representative engagement letter, the Shareholders’ Representative has not entered into any Contract, arrangement or understanding with the Company or any Company Holder, and the Company Holders do not have any requirements, prerequisites or veto rights in connection with the Shareholders’ Representative’s fulfillment of its obligations or exercise of its rights under this Agreement other than as set forth in such engagement letter.

(d) The Shareholders’ Representative shall treat confidentially any nonpublic information disclosed to it pursuant to this Agreement and shall not use such nonpublic information other than in the performance of its duties as the Shareholders’ Representative. In addition, the Shareholders’ Representative shall not disclose any nonpublic information disclosed to it pursuant to this Agreement to anyone except as required by Law; provided that (i) the Shareholders’ Representative may disclose such nonpublic information to legal counsel and other advisors under an obligation of confidentiality and non-use in its capacity as such (for the purpose of advising the Company Holders on any information disclosed to such Shareholders’ Representative pursuant to this Agreement), (ii) the Shareholders’ Representative (or legal counsel or other advisor to whom information is disclosed pursuant to clause (i) above) may disclose such nonpublic information disclosed to the Shareholders’ Representative pursuant to this Agreement in any Action relating to this Agreement or the transactions contemplated hereby (or, in either case, discussion in preparation therefor) and (iii) the Shareholders’ Representative may disclose to employees, advisors, agents or consultants of the Shareholders’ Representative and to any Company Holder (in each case who have a need to know such information and who are subject to confidentiality obligations with respect thereto) any such nonpublic information disclosed to the Shareholders’ Representative.

(e) Buyer shall be entitled to rely on the authority of the Shareholders’ Representative as the agent, representative and attorney-in-fact of the Company Holders for all purposes under this Agreement and shall have no Liability for any such reliance. No Company Holder may revoke the authority of the Shareholders’ Representative. Each Company Holder, by voting in favor of

33

or consenting to the Merger or by surrendering or delivering a Certificate or an affidavit in lieu thereof to the Paying Agent or the Company (or its designee payroll service provider), as applicable, along with an executed Letter of Transmittal hereby ratifies and confirms, and hereby agrees to ratify and confirm, any action taken by the Shareholders’ Representative in the exercise of the power-of-attorney granted to the Shareholders’ Representative pursuant to this Section 2.9, which power-of-attorney, being coupled with an interest, is irrevocable and shall survive the death, incapacity or incompetence of such Company Holder.

(f) At the Closing, Buyer shall pay the Shareholders’ Representative Fund Amount to the Shareholders’ Representative, which shall be maintained by the Shareholders’ Representative in a segregated account (the aggregate amount of cash so held by the Shareholders’ Representative from time to time, the “Shareholders’ Representative Fund”). The Shareholders’ Representative will hold these funds separate from its corporate funds, will not use these funds for its operating expenses or any other corporate purposes and will not voluntarily make these funds available to its creditors in the event of bankruptcy. The Company Holders shall not receive interest or other earnings on the Shareholders’ Representative Fund and the Company Holders irrevocably transfer and assign to the Shareholders’ Representative any ownership right that they may have in any interest that may accrue on funds held in the Shareholders’ Representative Fund. The Company Holders acknowledge that the Shareholders’ Representative is not providing any investment supervision, recommendations or advice. The Shareholders’ Representative shall have no responsibility or liability for any loss of principal of the Shareholders’ Representative Fund other than as a result of its bad faith, gross negligence or willful misconduct. For Tax purposes, the Shareholders’ Representative Fund shall be treated in accordance with Section 5.1(f). The Shareholders’ Representative shall be reimbursed for reasonable out-of-pocket expenses incurred in the performance of its duties (including the reasonable fees and expenses of counsel) under this Agreement from the Shareholders’ Representative Fund; provided that if the Shareholders’ Representative Fund is insufficient to pay such expenses, then the Shareholders’ Representative shall be reimbursed directly from the Company Holders on a several basis (and not a joint and several basis) according to their respective Pro Rata Percentages.

(g) Upon the determination of the Shareholders’ Representative that the Shareholders’ Representative Fund is to be distributed to the Company Holders, (i) the Shareholders’ Representative shall calculate the amount to be distributed to the Company Holders after (A) payment of all of the Shareholders’ Representative’s out-of-pocket expenses incurred in connection with its services as Shareholders’ Representative and (B) deduction of the Employer Tax Amount payable on or triggered by such payment of the portion of such amount to be paid to the Company Award Holders by the Surviving Corporation with the amount in clause (B) to be calculated iteratively, (ii) deposit with the Paying Agent such portion of the resulting amount payable to the Company Holders other than the Company Award Holders, and (iii) pay to the Surviving Corporation such portion of the resulting amount payable to the Company Award Holders plus the Employer Tax Amount calculated in clause (i)(B) above. The Paying Agent and the Surviving Corporation, as applicable, shall make payments to the Company Holders pursuant to the Allocation Schedule, less any applicable Tax withholding required by applicable Law; provided, however, than such amounts payable to the Company Award Holders shall in no event be paid more than five years following the Closing Date. Any portion of the Shareholders’ Representative Fund that remains undeliverable or unclaimed after twelve (12) months of the initial delivery attempt (or such earlier date, immediately prior to such time when the amounts

34

would otherwise escheat to or become property of any Governmental Entity by Law) shall become, to the extent permitted by Law, including any abandoned property, escheat or similar Law, the property of Buyer, free and clear of any claims or interest of any Person previously entitled thereto. The Shareholders’ Representative Fund shall not be available to Buyer to satisfy any claims in connection with this Agreement or the transactions contemplated hereby.

Section 2.10 Close of Stock Transfer Books. At the Effective Time, the stock transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers of shares of Company Capital Stock on the records of the Company unless and until reopened by the Surviving Corporation. From and after the Effective Time, no shares of Company Capital Stock shall be deemed to be outstanding, and the holders of shares of Company Capital Stock immediately prior to the Effective Time shall cease to have any rights with respect to such shares, except as otherwise provided herein or by applicable Law.

Section 2.11 Dissenting Shares.

(a) Notwithstanding anything in this Agreement to the contrary, any shares of Company Capital Stock outstanding immediately prior to the Effective Time and held by a holder who (i) voted against the Merger (if submitted for approval at a meeting of shareholders); (ii) did not consent in writing to the Merger (if submitted for approval by written consent in lieu of a meeting); or (iii) has not otherwise contractually waived its rights of dissent and appraisal, and, in each case, who has exercised and perfected its rights of dissent and appraisal for such shares in accordance with the Dissent Statute and has not effectively withdrawn or lost such rights of dissent and appraisal (collectively, the “Dissenting Shares”) shall not be converted into or represent the right to consideration for Company Capital Stock set forth in Section 2.7 and the holder or holders of such Dissenting Shares, but shall instead be converted into the right to receive such consideration as may be determined to be due with respect to any such Dissenting Shares pursuant to the Dissent Statute. Each holder of Dissenting Shares who, pursuant to the Dissent Statute, becomes entitled to payment thereunder for such shares shall receive payment therefor in accordance with the Dissent Statute (but only after the value therefor shall have been agreed upon or finally determined pursuant to such provisions).

(b) Notwithstanding the provisions of Section 2.11(a), if any holder of Dissenting Shares shall effectively withdraw or lose (through failure to perfect or otherwise) such holder’s rights to dissent and appraisal under the Dissent Statute, or a court of competent jurisdiction shall determine that such holder is not entitled to relief provided under the Dissent Statute, then, as of the later of the Effective Time and the occurrence of such event, such holder’s shares of Company Capital Stock shall automatically be converted into and represent only the right to receive the consideration for Company Capital Stock set forth in Section 2.7, without interest, following surrender of the certificate representing such shares of Company Capital Stock in the manner provided in Section 2.8 or, in the case of a lost, stolen, mutilated, defaced or destroyed certificate, upon delivery of the documents, if required, described in Section 2.8.

(c) After the Effective Time, the Surviving Corporation shall give the Shareholders’ Representative prompt notice of any written demands for appraisal, negotiations between the Surviving Corporation and any holders of Dissenting Shares, withdrawals of demands for appraisal and any other related instruments served on or by the Surviving Corporation.

No later than four (4) Business Days prior to the Closing Date, the Company shall prepare in good faith and provide to Buyer a statement setting forth in reasonable detail its good faith estimate of the estimated Closing Net Working Capital, the estimated Closing Indebtedness Amount, the estimated Closing Cash Amount, the estimated Seller Transaction Expenses and the estimated Change of Control Payments (the “Estimated Closing Statement”). The Estimated Closing Statement shall be prepared in accordance with the Accounting Principles.

(b) Estimated Closing Cash Payment. The amount of the Closing Cash Payment shall be calculated using the estimated Closing Net Working Capital, estimated Closing Indebtedness Amount, the estimated Closing Cash Amount, the estimated Seller Transaction Expenses and the estimated Change of Control Payments set forth in the Estimated Closing Statement, which shall be subject to a “true-up” adjustment after the Closing pursuant to Section 2.12(f).

(c) Proposed Final Closing Statement. Not later than ninety (90) days after the Closing Date, Buyer shall prepare or cause to be prepared, and deliver to the Shareholders’ Representative, a statement setting forth in reasonable detail its proposed final determination of the Closing Net Working Capital, Closing Indebtedness Amount, the Closing Cash Amount, the Seller Transaction Expenses and the Change of Control Payments (the “Proposed Final Closing Statement”). The Proposed Final Closing Statement will be prepared in accordance with the Accounting Principles and in accordance with the definitions in this Agreement. Notwithstanding anything to the contrary in this Agreement, any calculations with respect to Taxes in the Estimated Closing Statement and the Proposed Final Closing Statement shall be calculated as of the end of the day on the Closing Date taking into account the effect of the transactions contemplated by this Agreement. The Shareholders’ Representative and its Representatives shall have reasonable access to the books, records (including work papers, schedules, memoranda and other documents), supporting data, facilities and employees of the Surviving Corporation for purposes of assisting the Shareholders’ Representative and its Representatives in their review of the Proposed Final Closing Statement and the Buyer shall cooperate with the Shareholders’ Representative and its Representatives in good faith in connection with such review; provided, that such access shall be limited to normal business hours.

(d) Dispute Notice. The Proposed Final Closing Statement will be final, conclusive and binding on the Parties unless the Shareholders’ Representative provides a written notice (a “Dispute Notice”) to Buyer no later than the twentieth (20th) Business Day after the delivery to the Shareholders’ Representative of the Proposed Final Closing Statement. Any Dispute Notice must set forth, based upon the information available to the Shareholders’ Representative, in reasonable detail the Shareholders’ Representative’s alternative calculation of the Closing Net Working Capital, the Closing Indebtedness Amount, the Closing Cash Amount, the Seller Transaction Expenses and the Change of Control Payments, as applicable. For the avoidance of doubt, any item not included in the Dispute Notice shall be considered final and binding.

(e) Resolution of Disputes. Buyer and Shareholders’ Representative will attempt to promptly resolve the matters raised in any Dispute Notice in good faith. If the Parties have not resolved the matters raised in any Dispute Notice, within ten (10) Business Days after the date of

36

delivery of any Dispute Notice pursuant to Section 2.12(d) either Buyer or Shareholders’ Representative may provide written notice to the other (the “Dispute Submission Notice”) that it elects to submit the disputed items to a nationally recognized independent accounting firm chosen jointly by Buyer and the Shareholders’ Representative (the “Accounting Firm”). In the event that an Accounting Firm has not been selected by mutual agreement of Buyer and the Shareholders’ Representative within ten (10) Business Days following the giving of the Dispute Submission Notice, each of Buyer and the Shareholders’ Representative shall promptly select an accounting firm and promptly cause such two accounting firms to mutually select a third independent accounting firm to act as the Accounting Firm within twenty (20) Business Days of the giving of the Dispute Submission Notice. The Accounting Firm will promptly, in accordance with the rules set forth in the Accounting Firm’s engagement letter and its customary practices review only those unresolved items and amounts specifically set forth and objected to in the Dispute Notice and resolve the dispute with respect to each such specific unresolved item and amount in accordance with this Agreement. In any such case, a single partner of the Accounting Firm selected by such Accounting Firm in accordance with its normal procedures and having expertise with respect to settlement of such disputes and the industry in which the Surviving Corporation operates shall act for the Accounting Firm in the determination proceeding, and the Accounting Firm shall render a written decision as to each disputed matter, including a statement in reasonable detail of the basis for its decision. In no event shall the decision of the Accounting Firm provide for a calculation of the Closing Net Working Capital, the Closing Indebtedness Amount, the Closing Cash Amount, the Seller Transaction Expenses or the Change of Control Payments that is less than or greater than the calculation thereof shown in the Proposed Final Closing Statement or less than or greater than the Shareholders’ Representative’s alternative calculation thereof shown in the Dispute Notice. The fees and expenses of the Accounting Firm shall be borne equally by Buyer and the Shareholders’ Representative (on behalf of the Company Holders). The decision of the Accounting Firm with respect to the disputed items of the Proposed Final Closing Statement submitted to it will be final, conclusive and binding on the Parties. As used herein, the Proposed Final Closing Statement, as adjusted to reflect any changes agreed to by the Parties and the decision of the Accounting Firm, in each case, pursuant to this Section 2.12(e), is referred to herein as the “Final Closing Statement”. Each of the Parties to agrees to use its commercially reasonable efforts to cooperate with the Accounting Firm (including by executing a customary engagement letter reasonably acceptable to it) and to cause the Accounting Firm to resolve any such dispute as soon as practicable after the commencement of the Accounting Firm’s engagement.

(f) Closing Cash Payment Adjustment. If any of the Closing Net Working Capital, the Closing Indebtedness Amount, the Closing Cash Amount, the Seller Transaction Expenses or the Change of Control Payments (as finally determined pursuant to this Section 2.12 and as set forth in the Final Closing Statement) differs from the estimated amount thereof set forth in the Estimated Closing Statement, the following shall occur:

(i) the Closing Cash Payment shall be recalculated using the Closing Net Working Capital, the Closing Indebtedness Amount, the Closing Cash Amount, the Seller Transaction Expenses or the Change of Control Payments, as applicable, in the Final Closing Statement in lieu of the Closing Net Working Capital, the Closing Indebtedness Amount, the Closing Cash Amount or the Seller Transaction Expenses, as applicable, in the Estimated Closing Statement (such recalculated Closing Cash Payment, the “Final Closing Cash Payment”);

37

(ii) if the Final Closing Cash Payment exceeds the Closing Cash Payment paid at Closing, Buyer shall, within five (5) Business Days, (A) calculate the amount of such excess to be paid to the Company Holders, after deduction of the Employer Tax Amount payable on or triggered by the payment of the portion of such amount to be paid to the Company Award Holders by the Surviving Corporation, with the amount in this clause (A) to be calculated iteratively, (B) deliver or cause to be delivered to the Paying Agent by wire transfer of immediately available funds, a portion of the resulting excess amount for further disbursement to the Company Holders other than the Company Award Holders, and (C) deliver to the Surviving Corporation the balance of such resulting excess amount for further disbursement to the Company Award Holders, in the case of clauses (B) and (C) above, each pro rata in accordance with their respective Pro Rata Percentages as a portion of the Merger Consideration payable to the Company Holders pursuant to Section 2.7(c) or Section 2.7(d), as applicable. The Shareholders’ Representative shall calculate the amount to be distributed to each Company Holder according to each Company Holder’s respective Pro Rata Percentage and the Paying Agent or the Surviving Corporation, as applicable, shall disburse such amounts to the Company Holders, less applicable Tax withholding; or

(iii) if the Final Closing Cash Payment is less than the Closing Cash Payment paid at Closing (such shortfall, the “Overpayment Amount”), the Shareholders’ Representative and Buyer shall, within five (5) Business Days, instruct the Escrow Agent to release from the Escrow Fund the lesser of (x) the Overpayment Amount and (y) the then-existing balance of the Escrow Fund to Buyer by wire transfer of immediately available funds, to the account designated by Buyer, such Overpayment Amount; provided that payment from the Escrow Fund shall be the Buyer’s sole and exclusive remedy for the payment of the Overpayment Amount. For the avoidance of doubt, and without limiting the generality of the foregoing, no claim by Buyer for the payment of the Overpayment Amount shall be asserted directly against any of the Company Holders.

Section 2.13 Contingent Payments.

(a) Development Milestones. Subject to the Right of Setoff, Buyer shall make the payments described in Table 1 below (each, a “Development Milestone Payment”) following the first achievement or occurrence by or on behalf of the Buyer, a Rights Transferee or their respective Affiliates, of the corresponding event with respect to MT1621 or a MT1621 Backup (each a “Development Milestone Event”) described in the row to the left of such payment in Table 1. In no event shall more than one Development Milestone Payment be due for either of the two Development Milestone Events in Table 1.

Table 1

For clarity, if the two components of MT1621 are individually approved or if the applicable MT1621 Backup contains two components that are individually approved (i.e., any combination set forth in sub-clause (2) of the definition of MT1621 Backup) then the Development Milestone Events set forth in Table 1 above shall be deemed achieved upon obtaining Marketing Approval for both components in the applicable territory.

(i) From and after the Closing Date, not more than once during any six month period, Buyer shall schedule a meeting between the Development Milestone Review Committee and a senior representative of the Buyer, (a “Buyer Representative”) having knowledge of, and actively involved in managing, Buyer’s efforts to achieve the Development Milestone Events, by telephone conference, and such Buyer Representative shall provide a reasonable update on the progress of achieving the Development Milestone Events, and respond in reasonable detail, during such meeting if practicable (or, if not then practicable, as soon as reasonably practicable thereafter), to the Development Milestone Review Committee’s reasonable inquiries, in each case for the purpose of providing the Development Milestone Review Committee with an opportunity to inquire about efforts, progress and plans of the Buyer with respect to the Development Milestone Events. The foregoing obligations of Buyer are conditional on the agreement, in writing, from each member of the Development Milestone Review Committee to keep all such information confidential pursuant to a customary confidentiality agreement with Buyer containing restrictions on the use and disclose of confidential information of Buyer or its Affiliates (other than the use of such confidential information to exercise his or her rights under this Agreement), which agreement shall provide that such member of the Development Milestone Review Committee may share such information with its advisors and attorneys so long as such parties are subject to a confidentiality obligation with respect to such information. Upon the achievement of both of the Development Milestone Events or the mutual agreement of the Development Milestone Review Committee and the Buyer, the Buyer’s obligations under this Section 2.13(a)(i) shall terminate.

Concurrently with delivery of the Net Sales Report (or, if applicable, promptly following the delivery by the Accounting Firm of an audit report containing a final determination of the Accounting Firm), the Buyer shall (i) calculate the amount of the applicable Royalty Payment to be distributed to the Company Holders, after deduction of (A) any amounts payable by the Surviving Corporation from such Royalty Payment to the Company Award Holders or under the Royalty Payment Bonus Plan and (B) the Employer Tax Amount payable on or triggered by the payment of the portion of such amount to be paid by the Company Award Holders by the Surviving Corporation and the payment of such payments under the Royalty Payment Bonus Plan to the participants therein, if any, with such amounts in clauses (A) and (B) to be calculated iteratively, and (ii) pay to the Paying Agent such portion of the resulting Royalty Payment as is payable to the Company Holders other than the Company Award Holders for further disbursement to the Company Holders other than the Company Award Holders, and (iii) deliver or cause to be delivered to the Surviving Corporation the balance of such resulting Royalty Payment for further disbursement to the Company Award Holders, in the case of clauses (B) and (C) above, each pro rata in accordance with their respective Pro Rata Percentages as a portion of the Merger Consideration payable to the Company Holders pursuant to Section 2.7(c) and Section 2.7(d), as applicable; provided that the Shareholders’ Representative shall calculate the amount to be distributed to each Company Holder according to each Company Holder’s respective Pro Rata Percentage (and Buyer shall provide the Shareholders’ Representative with its calculation of the Employer Tax Amount payable on or triggered by the payment of the portion of such amount to be paid to the Company Award Holders), and the Paying Agent or the Surviving Corporation, as applicable, shall disburse such amounts to the Company Award Holders, less applicable Tax withholding.

(c) In the event of any Product Sale or Business Sale, after such Product Sale or Business Sale, revenues attributable to Company Products sold, licensed or otherwise transferred to a Third Party following a Product Sale or Business Sale will continue to be deemed Net Sales under this Agreement. In addition, upon the occurrence of any Product Sale or Business Sale during the Earnout Period, Buyer shall cause the acquiring Third Party to assume the obligations of Buyer (and Buyer shall remain responsible for such Third Party’s performance absent a novation; provided, however, that, prior to the fifth anniversary of the Closing Date, such novation shall be subject to the Shareholders’ Representative’s consent, such consent not to be unreasonably withheld, conditioned or delayed) under this Agreement, including this Section 2.13 with respect to any Company Product acquired by such Third Party. In the event of any assumption of any obligations of Buyer under the preceding sentence, the Third Party assuming such obligations shall enter into an agreement with the Shareholders’ Representative, on behalf of the Company Holders, in a form reasonably acceptable to the Shareholders’ Representative, agreeing to be bound by the applicable provisions of this Agreement, to ensure that the Company Holders’ rights to receive the Contingent Payments are not adversely affected by such Product Sale or Business Sale and following the execution of such agreement Buyer shall be released from all obligations under this Agreement (for the sake of clarity, it being understood that the foregoing provision shall not release Buyer from any obligations or liability with respect to any breaches of this Agreement that occurred prior to the applicable Product Sale or Business Sale).

(a) Written Report and Audit Rights.

(i) For each of the calendar quarters starting with the Closing Date and ending upon the expiration of the last Earnout Period to expire, Buyer will provide the Shareholders’ Representative with a written report within forty-five (45) days after the conclusion of each calendar quarter setting forth the aggregate Net Sales of the Company Products during the preceding calendar quarter, a calculation of corresponding Royalty Payment for such calendar quarter and the calculation described in clause (i) of the last paragraph of Section 2.13(b) (the “Net Sales Report”). The Buyer shall keep (and shall cause its Affiliates, including the Surviving Corporation to keep), for so long as required under Buyer’s internal records retention policies (but no less than two years), its books and records pertaining to the Net Sales of the Company Product with respect to each calendar year.

(ii) The Shareholders’ Representative may engage the Accounting Firm to conduct an audit of the Buyer and its Affiliates (including the Surviving Corporation) for the purposes of confirming the Royalty Payment for the prior calendar year, the calculation set forth in the Net Sales Report and the Buyer’s compliance with the Royalty Payments provisions of this Agreement, in accordance with the other provisions of this Section 2.14.

(iii) No earlier than forty-five (45) days following the Shareholders’ Representative’s request of an audit pursuant to this Section 2.14, Buyer shall afford the Accounting Firm reasonable access to and opportunity to examine such books and records of the Buyer, during regular business hours, in a manner designed to avoid undue disruption to the Buyer’s business and subject to execution and delivery to Buyer of a confidentiality agreement reasonably acceptable to Buyer for the sole purpose of determining compliance with the Royalty Payments provisions of this Agreement.

(iv) Each of the Shareholders’ Representative and the Buyer will be entitled to receive (substantially simultaneously) a report of the Accounting Firm with respect to its findings directly from the Accounting Firm, which report will disclose only the amount and accuracy of payments reported and actually paid or otherwise payable under this Agreement.

(v) The Shareholders’ Representative (on behalf of the Company Holders) will bear the full cost of such audit, unless such audit discloses that they Royalty Payment as calculated by the Buyer was less than ninety-five percent (95%) of the Royalty Payment calculated by the Accounting Firm, in which case, but subject to subsection (vi) below, the Buyer shall bear the reasonable cost of the Accounting Firm for such audit.

(vi) In the event of any dispute between the Shareholders’ Representative and Buyer regarding the findings of an audit under this Section 2.14(a), the Parties will initially attempt in good faith to resolve the dispute amicably between themselves, and if the Parties are unable to resolve such dispute within thirty (30) days after delivery to both Parties of the Accounting Firm’s report, Buyer will select, subject to the Shareholders’

42

Representative’s consent, such consent not to be unreasonably withheld, conditioned or delayed, an internationally recognized independent certified public accounting firm (other than the Accounting Firm) to resolve such dispute in accordance with such procedures as such independent accounting firm may determine, and such accounting firm’s determination will be binding on both Parties absent manifest error by such accounting firm.

(vii) The Shareholders’ Representative’s exercise of its audit rights under this Section 2.14 may not (A) be conducted with respect to any calendar year other than the three (3) calendar years immediately prior to the calendar year in which such audit right is exercised, (B) be conducted more than once in any twelve (12) month period, or (C) be repeated for any calendar year; except with respect to (B) and (C) if the previous audit revealed an underpayment error of greater than five percent (5%) for such calendar year.

(b) Following the Closing, by execution of this Agreement, Buyer agrees that it and its Affiliates shall use Commercially Reasonable Efforts to develop MT1621 and to file marketing authorization applications, and seek Marketing Approval, for MT1621 so as to achieve the Development Milestone Events and to use Commercially Reasonable Efforts to commercialize, promote and sell MT1621 in the United States and Major European Market Countries after Marketing Approval (including where required or reasonably prudent to obtain, pricing and reimbursement approvals) has been obtained in the applicable country. Buyer further agrees that it, the Surviving Corporation and their Affiliates will not take any action in bad faith that would reasonably be expected to undermine the achievement of the Milestones and the generation of Net Sales.

(c) After the Closing, no Company Holder may sell, exchange, transfer or otherwise dispose of his, her or its right to receive any portion of any Development Milestone Payment or Royalty Payments that become due and payable in accordance with this Section 2.14, other than (i) upon death by will or intestacy; (ii) by instrument to an inter vivos or testamentary trust in which the right to receive the Development Milestone Payment, Royalty Payment or portion thereof is to be passed to beneficiaries upon the death of the trustee; (iii) made pursuant to a court order; (iv) made by operation of law (including a consolidation or merger) or without consideration in connection with the dissolution, liquidation or termination of any corporation, limited liability company, partnership or other entity; (v) to any other Company Holder; (vi) to any Affiliate or Affiliates of such Company Holder, (vii) in the case of any Company Holder that is a partnership, corporation, limited liability company, trustee or similar entity, (x) to one or more partners, shareholders, members, beneficiaries or similar owners of or investors in such Company Holder or (y) a successor entity upon the sale or transfer of a substantial part of the assets of such Company Holder; or (viii) to any Person, with Buyer’s consent or, with respect to Royalty Payments, to any Person after giving notice to Buyer of its intention to assign its rights to receive all or any portion of its Royalty Payment, which notice shall disclose the identity of the transferee and provide a customary opinion of counsel that such assignment is exempt from (or not subject to) the registration and qualification requirements of the Securities Act; provided, however, that no Company Award Holder may sell, exchange, transfer or otherwise dispose of his, her or its right to receive any portion of any Development Milestone Payment or Royalty Payments to any Person pursuant to clauses (v) through (viii) without Buyer’s consent.

43

to this Section 2.14 shall be delivered to the Paying Agent or Surviving Corporation, as applicable, for further disbursement to such transferee in accordance with the terms of this Agreement. Any transfer in violation of this Section 2.14(c) shall be null and void and shall not be recognized by Buyer or the Surviving Corporation.

Buyer’s then current standard exchange rate methodology will be employed for the translation of foreign currency sales into Dollars, provided that such methodology is used by Buyer in the translation of its foreign currency operating results, is consistent with GAAP, and is audited by Buyer’s independent certified public accountants in connection with the audit of the consolidated financial statements of Buyer, and is used for Buyer’s external reporting of foreign currency operating results.

Section 2.15 Withholding. Notwithstanding anything in this Agreement to the contrary, each of Buyer, the Surviving Corporation, the Paying Agent and any other applicable withholding agent (each, a “Withholding Person”), will be entitled to deduct and withhold, or cause to be deducted and withheld, from any amount payable or consideration otherwise deliverable pursuant to or as contemplated by this Agreement to any Company Holders, recipients of Change of Control Payments, the Shareholders’ Representative on the Company Holders’ behalf, payments to participants in the Royalty Payment Bonus Plan, or any other Person, such amounts as are required to be deducted and withheld therefrom under applicable Tax Law and shall pay such amounts to the appropriate Taxing Authority.

Prior to withholding any amounts from a payment made hereunder other than by reason of withholding on compensatory amounts, Buyer (or the other applicable withholding agent) shall give the Person(s) concerned reasonable notice of the proposed withholding and the reasons therefor and provide such Person with a reasonable opportunity to provide any documentation to Buyer or the other applicable withholding agent in order to reduce or eliminate such withholding. To the extent amounts are so withheld and paid over to the appropriate Taxing Authority, the withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made.

For the avoidance of doubt, in no event shall any adjustment pursuant to this Section 2.16(c) increase the Contingent Payments.

Buyer, the Surviving Corporation and the applicable Company Holder shall file all Tax Returns consistently with the foregoing Tax treatment, except as otherwise expressly required by a Taxing authority.

(a) Buyer shall, or shall cause the Surviving Corporation to, assume, honor and fulfill all of the Employee Plans in accordance with their terms as in effect immediately prior to the date hereof of or as subsequently amended if and as permitted pursuant to the term of such Employee Plans. During the twelve (12) month period immediately following the Closing Date, Buyer shall provide, or shall cause the Surviving Corporation to provide, for each employee of the Company who continues as an employee of Buyer or the Surviving Corporation or any of their respective Affiliates during such period (collectively, the “Continuing Employees”), with (i) a base salary or wage rate no less favorable than the base salary or wage rate provided to such Continuing Employee as of immediately prior to the Effective Time; (ii) target annual cash bonus opportunities that are no less favorable than the target annual cash bonus opportunities provided to such Continuing Employee as of immediately prior to the Effective Time; and (iii) other employee

71

benefits that are substantially comparable, in the aggregate, to the employee benefits provided to (A) such Continuing Employee as of immediately prior to the Effective Time for so long as the Surviving Corporation continues to maintain the Employee Plans and (B) following the transfer of such Continuing Employees to the Buyer Plans, employees of Buyer who are similarly-situated to such Continuing Employee.

(b) Without limiting the generality of Section 5.7(a), Buyer shall, or shall cause the Surviving Corporation to (i) pay to the Continuing Employees their target bonus pursuant to the Company’s annual bonus plan prior to March 15, 2020 (subject to the continued employment of such employee through December 31, 2019 or the earlier termination of such employee by Buyer without “cause” or by such employee for “good reason” (each as defined in the Company’s Change of Control Severance Plan)), multiplied by a fraction, the numerator of which is the number of days elapsed between January 1, 2019 and the Closing and the denominator is 365, and (ii) include each Continuing Employee in the applicable annual bonus plan of Buyer or the Surviving Corporation for the fiscal year in which the Closing Date occurs, on a basis consistent with similarly-situated employees of Buyer, with such participation commencing as of the day after the Closing (so that each Continuing Employee shall be eligible for the full amount of such an annual bonus, pro-rated for the portion of the year following the Closing). For the avoidance of doubt, clause (i) of the immediately preceding sentence shall not require Buyer to, or to cause the Surviving Corporation to, provide any Continuing Employee who participates in the Company’s Change of Control Plan with a duplicate payment of his or her pro-rated target bonus in respect of the Company’s annual bonus plan for fiscal year 2019 in the event such Continuing Employee’s employment is terminated by Buyer without “cause” or by such employee for “good reason” prior to December 31, 2019.

(c) Buyer shall, or shall cause the Surviving Corporation or any of their respective Affiliates to (i) give full credit to each Continuing Employee for purposes of eligibility, vesting and the calculation of benefit accruals (including for purposes of vacation accruals) under any employee benefit plans or arrangements maintained by Buyer, its Affiliates, or the Surviving Corporation (collectively, the “Buyer Plans”) for such Continuing Employee’s service with, or credited by, the Company to the same extent recognized by the Company immediately prior to the Effective Time (other than with respect to any severance plan or equity arrangement or defined contribution plan); (ii) waive all limitations as to preexisting conditions, exclusions, waiting periods, actively at work requirements and evidence of insurability with respect to participation and coverage requirements applicable to each Continuing Employees under any Buyer Plan that is a welfare benefit plan that such employees may be eligible to participate in after the Closing Date and (iii) provide credit under any such welfare plan for any co-payments, deductibles and out-of-pocket expenditures for the remainder of the coverage period during which any transfer of coverage occurs; provided, however, that no such service shall be recognized or credit given to the extent such recognition or credit would result in the duplication of benefits.

(d) If requested by Buyer, effective no later than the day immediately prior to the Closing Date, the Company shall take all actions necessary to terminate any and all Employee Plans intended to qualify as qualified cash or deferred arrangements under Section 401(k) of the Code.

72

Nothing contained in this Section 5.7 or this Agreement is intended to (i) be treated as an amendment of any particular Employee Plan, or otherwise, or alter or limit the ability of the Company, Buyer or any of their respective Affiliates to amend, modify or terminate any compensation or benefit or employment plan, program, agreement or arrangement. No Continuing Employee (or current or former employee of the Company, Buyer or any of their respective Affiliates) shall be regarded for any purpose as a third-party beneficiary of this Agreement or have the right to enforce the provisions hereof.

Section 7.1 Termination Events. This Agreement may be terminated prior to Closing:

(a) by the mutual written consent of Buyer and the Company;

(b) by either the Company, on the one hand, or Buyer and Merger Sub, on the other hand, by written notice to the other party if the Merger shall not have been consummated on or before October 31, 2019 (the “Expiration Date”), except that no Party will be permitted to terminate this Agreement pursuant to the terms of this Section 7.1(b) if the failure to consummate the Merger on or prior to the Expiration Date is the result of such Party’s breach of this Agreement in any material respect;

(c) by either the Company, on the one hand, or Buyer and Merger Sub, on the other hand, by written notice to the other party if any Governmental Entity with jurisdiction over such matters shall have issued an Order permanently restraining, enjoining or otherwise prohibiting the Merger or any of the other transactions contemplated by this Agreement, and such Order shall have become final and nonappealable;

(d) by Buyer if (i) any representation or warranty of the Company or the Shareholders’ Representative contained in this Agreement was inaccurate or was breached as of the Agreement Date, or has become inaccurate or has been breached as of a date subsequent to the Agreement Date (as if made on such subsequent date), such that the condition set forth in Section 6.3(a) would not be satisfied on or before the Expiration Date or (ii) any of the covenants or obligations of the Company, the Shareholders’ Representative or Company Holders contained in this Agreement have been breached such that the condition set forth in Section 6.3(b) would not be satisfied on or before the Expiration Date; provided, however, that if an inaccuracy in or breach of any representation or warranty of the Company or the Shareholders’ Representative as of a date

81

subsequent to the Agreement Date or a breach of a covenant by the Company is curable through the use of commercially reasonable efforts from and after Buyer notifies the Company in writing of the existence of such inaccuracy or breach until the Expiration Date (the “Company Cure Period”), then Buyer 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, provided the Company, during the Company Cure Period, continues to exercise commercially reasonable efforts to cure such inaccuracy or breach (it being understood that Buyer may not terminate this Agreement pursuant to this Section 7.1(d) if Buyer is in material breach of this Agreement or if such breach by the Company is cured);

(e) by the Company if (i) any representation or warranty of either Buyer or Merger Sub contained in this Agreement was inaccurate or was breached as of the Agreement Date, or has become inaccurate or has been breached as of a date subsequent to the Agreement Date (as if made on such subsequent date), such that the condition set forth in Section 6.2(a) would not be satisfied on or before the Expiration Date or (ii) if any of Buyer’s or Merger Sub’s covenants contained in this Agreement have been breached such that the condition set forth in Section 6.2(b) would not be satisfied on or before the Expiration Date; provided, however, that if an inaccuracy in or breach of any representation or warranty of Buyer or Merger Sub as of a date subsequent to the Agreement Date or a breach of a covenant by Buyer or Merger Sub is curable by the same through the use of commercially reasonable efforts from and after the Company notifies Buyer in writing of the existence of such inaccuracy or breach until the Expiration Date (the “Buyer 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 Buyer Cure Period, provided Buyer or Merger Sub, during the Buyer Cure Period, continues to exercise commercially reasonable efforts to cure such inaccuracy or breach (it being understood that the Company may not terminate this Agreement pursuant to this Section 7.1(e) if the Company is in material breach of this Agreement or if such breach by the Buyer or Merger Sub is cured);

ARTICLE 8

INDEMNITY

Section 8.1 Indemnification of Buyer Indemnified Parties. Subject to the limitations set forth in Section 8.3 below, from and after the Effective Time, each Company Holder will severally (in accordance with each Company Holder’s Pro Rata Percentage), but not jointly, indemnify, defend and hold harmless the Buyer Indemnified Parties from and against any and all Damages incurred by such Person (such Damages, “Indemnifiable Damages”) resulting from:

(a) any breach of any representation or warranty made by the Company in this Agreement or in any other certificate executed in connection with this Agreement by the Company as of the Closing;

(b) any breach or failure to perform on or prior to the Closing any covenant or agreement herein by the Company that is required to be performed on or prior to the Closing;

(c) any inaccuracy contained in the Allocation Schedule as of the Closing;

(d) any payments made with respect to Dissenting Shares to the extent that such payments, in the aggregate, exceed the value of the consideration that otherwise would have been payable pursuant Section 2.7, as applicable, upon the exchange of such Dissenting Shares;

(e) the VAT Reclaim Amount to the extent Buyer or the Surviving Corporation (after having used commercially reasonable efforts to receive such payment) shall not have received a payment of the VAT Reclaim Amount from the applicable Governmental Entity prior to the release of the Escrow Fund; and

(f) any Taxes of the Company with respect to any Pre-Closing Tax Period; Taxes for which the Company (or any predecessor of the Company) is held liable under Treasury Regulations Section 1.1502-6 (or any similar provision of state, local or foreign Law) by reason of such entity being included in any consolidated, affiliated, combined or unitary group at any time on or before the Closing Date; and Taxes imposed on or payable by third parties with respect to which the Company has an obligation to indemnify such third party pursuant to a transaction consummated on or prior to the Closing.

Section 8.2 Indemnification of Company Holders. From and after the Effective Time, Buyer and Merger Sub hereby agree to indemnify, defend and hold harmless, jointly and severally, each Company Holder against and in respect of, and pay the Company Holder the amount of, any and all Damages that are directly or indirectly suffered or incurred by any of the Company Holders or to which any of the Company Holders may otherwise become directly or indirectly subject (regardless of whether or not such Damages relate to any Third-Party Claim), and that arise from or as a result of, or are directly or indirectly connected with any of the following:

(a) any breach of any representation or warranty made by Buyer or Merger Sub in this Agreement or in any other certificate executed in connection with this Agreement by the Buyer or Merger Sub as of the Closing; or

83

(b) any breach or failure to perform on or prior to the Closing any covenant or agreement herein by Buyer or Merger Sub that is required to be performed on or prior to the Closing.

Section 8.3 Limitations on Recovery. Recovery by the Buyer Indemnified Parties pursuant to this Agreement will be subject to the following limitations:

(a) Threshold to Recovery of Damages.

(i) No Buyer Indemnified Party may recover Indemnifiable Damages from the Escrow Fund or the Company Holders in respect of any indemnification pursuant to Section 8.1(a) (except with regard to a breach of a Fundamental Representation, an Extended IP Representation or claims arising as a result of fraud, which shall not be so limited or subject to any Deductible) until the aggregate amount (without duplication) of Indemnifiable Damages to the Buyer Indemnified Parties has exceeded $1,500,000 (the “Deductible”), in which event the Buyer Indemnified Parties shall, subject to the other limitations contained herein, be entitled to be indemnified for all Indemnifiable Damages that exceed the Deductible.

(b) Caps on Recovery of Indemnifiable Damages.

(i) Each Company Holder’s liability for the payment of Indemnifiable Damages pursuant to Section 8.1 shall be several (in accordance with each Company Holders’ Pro Rata Percentage) and not joint.

(ii) With regard to indemnification for Indemnifiable Damages under Section 8.1(a) (except with regard to a breach of a Fundamental Representation, Extended IP Representation, Tax Representation or claims arising as a result of fraud, which shall not be so limited), amounts retained in the Escrow Fund will serve as the Buyer Indemnified Parties’ sole source of recovery from the Company Holders, and with regard to indemnification for Indemnifiable Damages under Section 8.1(a) with regard to a breach of an Extended IP Representation, amounts retained in the Escrow Fund and the Right of Setoff will serve as the Buyer Indemnified Parties’ sole source of recovery from the Company Holders.

(iii) Until the fifth anniversary of the Closing Date, with regard to indemnification claims made by a Buyer Indemnified Party under Section 8.1(a) relating to or arising out of a breach of any of the Fundamental Representations or under Section 8.1(b)-(f), a Buyer Indemnified Party shall recover any Indemnifiable Damages to which it is entitled hereunder first (A) from the Escrow Fund and (B) solely to the extent amounts available in the Escrow Fund are insufficient to recover such Indemnifiable Damages, directly from each Company Holder, severally and not jointly, according to each such Company Holders’ Pro Rata Percentage of such Indemnifiable Damages, up to the aggregate amount actually received by such Company Holder pursuant to this Agreement. Notwithstanding the foregoing, if a Buyer Indemnified Party is entitled to indemnification under Section 8.1(a) relating to or arising out of a breach of any of the Fundamental Representations, the Extended IP Representations, the Tax Representations, under Section

84

8.1(b)-(f) or as a result of fraud in excess of the amounts then remaining in the Escrow Fund (or in the event that the Escrow Fund has already been exhausted or terminated), and Buyer has delivered a Claim Certificate (as defined in Section 8.4) with respect thereto, Buyer shall have the right but not the obligation to setoff, on a dollar for dollar basis, the amount of Indemnifiable Damages (in the case of the Fundamental Representations and the Tax Representations, or under Section 8.1(b)-(f) or as a result of fraud) or [***] the amount of Indemnifiable Damages (in the case of the Extended IP Representations) reasonably determined by the Buyer Indemnified Party as necessary to satisfy then pending claims brought by a Buyer Indemnified Party in respect of such indemnification rights arising from such claim against Contingent Payments payable (but not any Contingent Payments previously paid) to the Company Holders (the “Right of Setoff”). Once such claim is finally determined in accordance with this Agreement, if the Indemnifiable Damages relating to such claim are determined to be less than the amount setoff against the applicable Contingent Payment, or if the Buyer Indemnified Party is determined not to be entitled to indemnification with respect to such claim, Buyer shall promptly, and in any event within five (5) Business Days, deliver (i) to the Surviving Corporation for further distribution by the Surviving Corporation to the applicable Tax authorities, the Employer Tax Amount arising out of the payment of the amounts described in clause (ii)(B) below to the Company Award Holders, (ii) after deduction of the Employer Tax Amount described in clause (i), (A) to the Paying Agent for further disbursement to the Company Holders (pro rata in accordance with their respective Pro Rata Percentages) such remaining portion of the amount equal to the remaining amount of such Contingent Payment payable to the Company Holders other than the Company Award Holders, as applicable, and (B) to the Surviving Corporation for further disbursement to the Company Award Holders (pro rata in accordance with their respective Pro Rata Percentages) an amount equal to the portion of the remaining amount of such Contingent Payment, less applicable Tax withholding. After the five (5) year anniversary of the Closing Date, a Buyer Indemnified Party may recover for indemnification claims under Section 8.1(a) relating to or arising out of a breach of any of the Fundamental Representations, the Extended IP Representations or the Tax Representations, or under Section 8.1(b)-(f); provided such recovery shall be limited to the Right of Setoff.

(c) No Buyer Indemnified Party shall be entitled to recover any Indemnifiable Damages with respect (i) to any Liability reflected in the Estimated Closing Statement, up to the amount of such Liability reflected in the Estimated Closing Statement or (ii) to the extent that the Buyer Indemnified Parties have already recovered the same Indemnifiable Damages with respect to such indemnifiable matter pursuant to any other provision of this Agreement.

(d) The Buyer Indemnified Parties shall take such commercially reasonable actions as are available to them to mitigate the amount of any Damages (other than mitigation efforts that would be harmful to Buyer or the business of the Company; provided that a mitigation effort shall not be considered harmful to Buyer or the business of the Company simply because it will limit Buyer’s recovery for Indemnifiable Damages in accordance with this Article 8). The amount of Indemnifiable Damages payable under this Article 8 shall be reduced by (i) any insurance proceeds actually received from an insurance carrier by the Buyer Indemnified Party with respect thereto (net of any applicable deductibles or similar costs or payments), (ii) indemnity or contribution amounts actually received from third parties (net of any applicable costs of recovery or collection

85

thereof) and (iii) any tax deduction or other tax benefit, if any, actually recognized by any Indemnified Party as a result of incurring such Damages in the Taxable year in which such Damages are incurred; provided, that nothing in this Section 8.3(d) shall require a Buyer Indemnified Party to litigate any dispute to obtain any insurance proceeds, indemnity or contribution amount; provided, further, that if a Buyer Indemnified Party receives insurance proceeds, indemnity or contribution amounts or recognizes tax benefits, including the receipt of tax refunds or a reduction in cash taxes payable, after having received payment from (or on behalf of) any Company Holders with respect to any Indemnifiable Damages, such Buyer Indemnified Party shall pay to the Shareholders’ Representative the lesser of (x) the amount of the insurance proceeds received and tax benefits and (y) the amount of indemnification received by the Buyer Indemnified Party from the Company Holders, and the Shareholders’ Representative will distribute such funds to the Company Holders in accordance with their Pro Rata Percentage.

(e) Materiality standards or qualifications or any references to Material Adverse Effects in any representation, warranty or covenant shall not be taken into account in determining whether a breach of or default in connection with such representation, warranty or covenant (or failure of any representation or warranty to be true and correct) exists, or in determining the amount of any Indemnifiable Damages with respect to such breach, default or failure.

(f) Indemnifiable Damages will be limited to actual Damages incurred by the Indemnified Parties and will exclude exemplary or punitive Damages, or special Damages that are in the nature of exemplary or punitive Damages (except to the extent such types of Damages are specifically awarded by an arbitrator or Governmental Entity to a third party and paid to such third party by an Indemnified Party in connection with a Third-Party Claim).

Section 8.4 Notification of Certain Claims.

(a) If a Buyer Indemnified Party or Company Holder (each, an “Indemnified Party”) believes that it has a bona fide claim for indemnification pursuant to this Article 8, other than in respect of a Third-Party Claim, then Buyer (if such Indemnified Party is a Buyer Indemnified Party) or the Shareholders’ Representative (if such Indemnified Party is a Company Holder), as the case may be, shall promptly deliver to the Shareholders’ Representative or Buyer, respectively, a certificate (any certificate delivered in accordance with the provisions of this Section 8.4(a), a “Claim Certificate”): (i) stating that an Indemnified Party has a claim for indemnification pursuant to this Article 8; (ii) containing a calculation, prepared in good faith, of the amount to which such Indemnified Party claims to be entitled to receive, which shall be the amount of Damages such Indemnified Party claims to have so incurred or suffered or could reasonably be expected to incur or suffer and (iii) specifying in reasonable detail (based upon the information then possessed by Buyer or the Shareholders’ Representative, as the case may be) the material facts known to the Indemnified Party giving rise to such claim.

(b) Buyer is the sole and exclusive Person authorized to act for and bring claims on behalf of Buyer Indemnified Parties, and the Shareholders’ Representative is the sole and exclusive Person authorized to act for and bring claims on behalf of Company Holders.

86

(c) No delay in providing such Claim Certificate will affect an Indemnified Party’s rights hereunder except to the extent that (and then only to the extent that) the indemnifying party is adversely prejudiced thereby.

(d) If the Escrow Fund is available to satisfy the recovery of the claim asserted in such Claim Certificate and has not been fully released, at the time of delivery of any Claim Certificate to the Shareholders’ Representative, a duplicate copy of such Claim Certificate shall be delivered to the Escrow Agent by or on behalf of Buyer (on behalf of itself or any other Buyer Indemnified Party).

(e) If the Shareholders’ Representative or Buyer, as the case may be, objects to any claim made in any Claim Certificate, then the Shareholders’ Representative or Buyer, as the case may be, shall deliver a written notice (a “Claim Dispute Notice”) to Buyer or the Shareholders’ Representative, as the case may be, during the 30-day period commencing upon receipt by the Shareholders’ Representative or Buyer, as the case may be, of the Claim Certificate. The Claim Dispute Notice will set forth the principal basis for the dispute of any claim made in the applicable Claim Certificate. If the Shareholders’ Representative or Buyer, as the case may be, does not deliver a Claim Dispute Notice hereunder prior to the expiration of such 30-day period, then such claim for indemnification set forth in such Claim Certificate shall be deemed to have been conclusively determined in favor of the Indemnified Party that delivered the Claim Certificate for purposes of this Article 8 on the terms set forth in the Claim Certificate and the applicable Indemnified Party will be indemnified for the amount of the Damages set forth in the Claim Certificate pursuant to this Article 8.

(f) If a Claim Dispute Notice is properly delivered hereunder, then Buyer and the Shareholders’ Representative will attempt in good faith to resolve any such objections raised in such Claim Dispute Notice. If Buyer and the Shareholders’ Representative agree to a resolution of such objection, then a memorandum setting forth the matters conclusively determined by Buyer and the Shareholders’ Representative will be prepared and signed by both Parties.

(g) If no such resolution can be reached during the 30-day period following receipt of a given Claim Dispute Notice hereunder, then upon the expiration of such 30-day period, either Buyer or the Shareholders’ Representative may bring suit to resolve the objection in accordance with Section 9.5.

Section 8.5 Third Party Claims.

(a) If a Buyer Indemnified Party or Company Holder receives notice of any Action that has been or may be brought or asserted by a third party against such Indemnified Party and that may give rise to a claim by such Indemnified Party for Damages under this Article 8 (each, a “Third-Party Claim”), such Indemnified Party will, promptly after receipt of notice of any such Third-Party Claim, notify the Shareholders’ Representative of such Third-Party Claim where one or more of the Company Holders are the Person(s) from whom indemnification is sought and notify Buyer where Buyer is the Person from whom indemnification is sought, in each case by the delivery of a certificate regarding the same, which shall be deemed a Claim Certificate. The failure of an Indemnified Party to so notify the party from whom indemnification is being sought of the commencement of any such Third-Party Claim will not relieve any party from liability in

87

connection therewith, except to the extent that such failure materially and adversely affects the ability of such party from whom indemnification is being sought to defend its interests in such Third-Party Claim.

(b) Buyer, upon written notice to the Shareholders’ Representative, will have the right in its sole discretion to assume and control the defense of any such Third-Party Claim; provided that the Shareholders’ Representative and its counsel (at Shareholders’ Representative’s sole expense on behalf of the Company Holders) may participate in (but not control the conduct of) the defense of such Action except to the extent such participation would adversely affect any privilege of Buyer or a Buyer Indemnified Party in respect of such Third-Party Claim. Buyer will have the right, in its sole discretion, to settle any Third-Party Claim, but no settlement of any such Third-Party Claim with third party claimants will be determinative of whether such Third-Party Claim gives rise to any right to indemnification hereunder, and, if so, the amount of, Damages under this Article 8 relating to such matter unless the Shareholders’ Representative consents to such settlement (and the Company Holders shall have no obligation to indemnify any Buyer Indemnified Party for any Damages payable pursuant to a settlement to the extent that such settlement is not reasonable, including in the amount of costs and expenses agreed to in such settlement). In the event that the Shareholders’ Representative has consented to any such settlement, the Company Holders will have no power or authority to object under any provision of this Article 8 to the amount of Damages with respect to such settlement.

(c) If requested by Buyer, the Shareholders’ Representative will enter into a separate confidentiality or joint defense agreement prior to participating in the defense of any Third-Party Claim.

(d) The party controlling the defense of a Third-Party Claim will (i) keep the non-controlling party reasonably advised of the status of such Third-Party Claim and the defense thereof and will consider in good faith recommendations made by the non-controlling party with respect thereto and (ii) make available to the non-controlling party any documents or materials in its possession or control that may be necessary to understand the defense of such claim (subject to confidentiality obligations and the protection of the attorney-client privilege). The non-controlling party will reasonably cooperate with and assist the controlling party in the defense of such Third-Party Claim, including by furnishing the controlling party with such information as it may have with respect to such Third-Party Claim (including copies of any summons, complaints or other proceedings which may have been served on such party and any written claim, demand, invoice, billing or other document evidencing or asserting the same).

(e) Costs and expenses (including attorneys’ fees, costs and other expenses incurred in investigating, preparing or defending any applicable claim or Action) shall constitute Indemnifiable Damages for which a Buyer Indemnified Party is entitled to indemnification if and solely to the extent that such underlying claim or Action gives rise to Indemnifiable Damages for which an Indemnified Party is entitled to indemnification pursuant to Section 8.1(a) (without taking into account such costs and expenses).

Section 8.6 Treatment of Adjustments. The Company Holders, on the one hand, and Buyer and Merger Sub, on the other hand, agree that, except as otherwise required by applicable Law, all payments made by or on behalf of either of them to or for the benefit of the other

88

(including any payments to the Company) under this Article 8 will be treated as adjustments to the consideration payable pursuant to this Agreement for Tax purposes and that such treatment will govern for purposes hereof.

Section 8.7 Exclusive Remedy. Notwithstanding any other provision of this Agreement to the contrary, this Article 8, will be the sole and exclusive remedy of the Buyer Indemnified Parties and the Company Holders from and after the Closing Date for any claims arising under this Agreement; provided, however, that the foregoing sentence will not be deemed a waiver by any party of any right to specific performance or injunctive or equitable relief, any right or remedy arising from a criminal Action, or any right or remedy arising by reason of any claim of fraud.

ARTICLE 9

(a) Each Party irrevocably submits to the exclusive jurisdiction of the Delaware Chancery Court, and any federal court of the United States of America sitting in the State of Delaware, for the purposes of any suit, action or other proceeding arising out of this Agreement or any transaction contemplated hereby. Each Party agrees to commence any such action, suit or proceeding either in the Delaware Chancery Court or if such suit, action or other proceeding may not be brought in such court for jurisdictional reasons, in any federal court of the United States of America sitting in the State of Delaware. Each Party further agrees that service of any process, summons, notice or document by the U.S. registered mail to such Party’s respective address set forth above shall be effective service of process for any action, suit or proceeding in Delaware with respect to any matters to which it has submitted to jurisdiction in this Section 9.5. Each Party irrevocably and unconditionally waives any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement or the transactions contemplated hereby in (i) the Delaware Chancery Court, and (ii) any federal court of the United States of America sitting in the State of Delaware, and hereby and thereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum. This Section 9.5 shall not apply to any dispute under Section 2.12 that is required to be decided by the Accounting Firm.

(b) EACH PARTY HERETO WAIVES ITS RIGHT TO TRIAL OF ANY ISSUE BY JURY.

Section 9.7 Entire Agreement. This Agreement, together with all annexes, schedules (including the Disclosure Schedule) and exhibits and all ancillary agreements, documents or instruments to be delivered in connection herewith and therewith, contain the entire agreement and understanding between the Parties with respect to the subject matter hereof and thereof and supersede all prior discussions, negotiations, commitments, agreements and understandings, both written and oral, relating to such subject matter.

Section 9.8 No Third-Party Beneficiaries. Except as otherwise provided in Section 5.2, this Agreement is for the sole benefit of the Parties and their permitted successors and assigns and nothing herein expressed or implied shall give or be construed to give to any Person, other than the Parties and such successors and assigns, any legal or equitable rights hereunder.

Section 9.9 Counterparts. This Agreement may be executed in any number of counterparts and by the Parties in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. This Agreement may be executed by facsimile, .pdf or other electronically transmitted signatures and such signatures shall be deemed to bind each Party hereto as if they were the original signatures.

Section 9.10 Governing Law. This Agreement and all matters relating to or arising out of this Agreement (whether sounding in contract, tort or otherwise) shall be governed by, and construed in accordance with, the substantive Laws of the State of Delaware, regardless of the Laws that might otherwise govern under applicable principles of conflict of laws thereof.

Section 9.11 Specific Performance. Each of the Parties hereby agrees that irreparable damage would occur (for which monetary relief, even if available, would not be an adequate remedy) in the event that any of the provisions of this Agreement were not performed by Buyer, Merger Sub or the Company, as applicable, in accordance with their specific terms or were otherwise breached by Buyer, Merger Sub or the Company, as applicable, including if the parties hereto fail to take any action required of them hereunder to consummate the transaction contemplated by this Agreement. It is accordingly agreed that (i) the Parties shall be entitled to an injunction or injunctions, specific performance, or other equitable relief to prevent breaches of this Agreement by any of Buyer, Merger Sub or the Company, as applicable, and to enforce specifically the terms and provisions hereof against Buyer, Merger Sub or the Company, as applicable, in any court having jurisdiction, without proof of damages or otherwise, this being in addition to any other remedy to which the parties hereto are entitled at law or in equity and (ii) the right of specific performance and other equitable relief is an integral part of the transactions contemplated by this Agreement and without that right, neither the Company nor Buyer would have entered into this Agreement. The Parties agree not to assert that a remedy of specific performance or other equitable

93

relief 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 this Section 9.11 shall not be required to provide any bond or other security in connection with any such order or injunction. Notwithstanding anything herein to the contrary, in no event shall this Section 9.11, be used, alone or together with any other provision of this Agreement, to require the Company to remedy any breach of any representation or warranty of the Company made herein.

Section 9.12 Representation. Each of the Parties hereby agrees, on its own behalf and on behalf of its directors, members, partners, officers, employees and Affiliates, that Fenwick & West LLP may serve as counsel to each and any of the Shareholders’ Representative, the Company Holders and their respective Affiliates (individually and collectively, the “Seller Group”), on the one hand, and the Company and its Subsidiaries, on the other hand, in connection with the negotiation, preparation, execution and delivery of this Agreement and the consummation of the transactions contemplated hereby, and that, following consummation of the transactions contemplated hereby, Fenwick & West LLP (or any successor) may serve as counsel to the Seller Group or any director, member, partner, officer, employee or Affiliate of the Seller Group, in connection with any litigation, claim or obligation arising out of or relating to this Agreement or the transactions contemplated by this Agreement notwithstanding such representation of the Company or its Subsidiaries, even though the interests of the Shareholders’ Representative, the Company Holders and other members of the Seller Group may be directly adverse to Buyer, the Surviving Corporation or any of their respective Subsidiaries, and each of the Parties hereby consents thereto and waives any conflict of interest arising therefrom, and each of such Parties shall use commercially reasonable efforts to cause any Affiliate thereof to consent to waive any conflict of interest arising from such representation. The Parties agree that any privilege attaching as a result of Fenwick & West LLP representing the Company or its Subsidiaries in connection with the transactions contemplated by this Agreement, including the negotiation, preparation, execution, delivery and closing under, or any dispute arising in connection with, this Agreement or any agreement entered into pursuant to this Agreement, shall survive the Closing and shall remain in effect, provided that such privilege from and after the Closing shall be controlled by the Shareholders’ Representative, and all communications prior to the Closing between the Company or any of its employees, directors or advisors, the Shareholders’ Representative, any Company Holder or any other member of the Seller Group, and any third parties, on the one hand, and Fenwick & West on the other, shall be deemed to be the confidential communications of the Company Holders and the Shareholders’ Representative (and shall be controlled by the Shareholders’ Representative). As to any privileged attorney-client communications between Fenwick & West LLP and the Company or any of its employees, directors or advisors, the Shareholders’ Representative, any Company Holder or any other member of the Seller Group prior to the Closing Date (collectively, the “Privileged Communications”), each of Buyer, Merger Sub, the Company, and its Subsidiaries together with any of their respective Affiliates, Subsidiaries, successors or assigns, agree that no such party may use or rely on any of the Privileged Communications in any action against or involving any member of the Seller Group, after the Closing. Notwithstanding the foregoing, in the event that a dispute arises between Buyer, the Surviving Corporation or any of their respective Affiliates, on the one hand, and a Person other than a member of the Seller Group, on the other hand, after the Closing, Buyer, the Surviving

94

Corporation and any of their respective Affiliates may assert the attorney-client privilege to prevent disclosure to such third-party of such privileged communications; provided that none of Buyer, the Surviving Corporation or any of their respective Affiliates may waive such privilege without the prior written consent of the Shareholders’ Representative.

Section 9.13 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible to the fullest extent permitted by applicable Law in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

For purposes of this Agreement, the term “Registrable Securities” shall mean all of the shares of Buyer Common Stock to be issued to Company Holders under this Agreement (the “Closing Shares”) other than shares of Buyer Common Stock issued to a Company Holder that has not provided the information required by paragraph 7 one Business Day prior to the filing of the Resale Registration Statement.

Section 2. Resale Registration Statement. Buyer agrees that it will file a prospectus supplement to Buyer’s registration statement on Form S-3ASR filed October 2, 2017 (File No. 333-220759) (or another registration statement on Form S-3, or such other form under the Securities Act then available to Buyer), providing for the resale pursuant to Rule 415 from time to time, and on a continuing basis, by each holder thereof (each a “Holder”), of the Registrable Securities (such registration statement, including the prospectus, any pre-effective or post-effective amendments and supplements thereto, all exhibits thereto and all material incorporated by reference or deemed to be incorporated by reference, if any, therein being hereinafter referred to as the “Resale Registration Statement” and such prospectus supplement, including the base prospectus included in the Resale Registration Statement, the “Resale Prospectus Supplement”). Buyer agrees to file the Resale Prospectus Supplement within two (2) Business Days after the Closing Date; provided, however, that Buyer will be permitted to postpone or suspend (upon written notice to the Holders) the use of the Resale Prospectus Supplement or the Resale Registration Statement (on one or more occasions) (a) if the disclosure requirements of the Securities Act in connection with the Resale Registration Statement would require Buyer to include material information (including information to supplement, update or correct existing disclosures) that has not theretofore been included or incorporated by reference in the Resale Registration Statement and Buyer’s Board of Directors has determined in its reasonable judgment that Buyer has a bona fide business reason not to disclose such material information; provided, that the aggregate number of days Buyer shall be permitted to so postpone or suspend the use of the Resale Prospectus Supplement or effectiveness of the Resale Registration Statement shall not exceed thirty (30) consecutive days or an aggregate of sixty (60) days in any period of twelve (12) consecutive months, or (b) if the SEC shall determine (and notify Buyer) that financial statements required to be included or incorporated by reference in the Resale Registration Statement or Resale Prospectus Supplement pursuant to Rules 3-05 and 11-01 of Regulation S-X promulgated by the SEC related to an acquisition by the Company are not yet so included or incorporated; provided, that (1) Buyer shall consult with the Holders promptly upon receipt of any such notice and shall permit counsel for the Holders to participate in any discussions with the SEC regarding such determination; (2) such postponement or suspension of the use of the Resale Prospectus Supplement or effectiveness of the Resale Registration Statement shall only continue until such time any such required financial statements are included or incorporated; and (3) Buyer shall be not permitted to so postpone or suspend the use of the Resale Prospectus Supplement or the Resale Registration Statement after (or for a period ending after) the date five Business Days after the Closing Date.

Section 3. Withdrawal. Any Holder on behalf of whom any Registrable Securities have been included in the Resale Prospectus Supplement shall have the right to withdraw any or

(b) notify as promptly as reasonably practicable each seller of Registrable Securities of each of (A) the filing of the Resale Prospectus Supplement and any amendment or supplements thereto, (B) the receipt of any comments from the SEC or any state securities law authorities or any other governmental authorities with respect to any such registration statement or Resale Prospectus Supplement or any amendments or supplements thereto, and (C) any oral or written stop order with respect to such registration, any suspension of the registration or qualification of the sale of such Registrable Securities in any jurisdiction, or any initiation or threatening of any proceedings with respect to any of the foregoing; provided that Buyer shall not be required to notify sellers of Registrable Securities of any events described in (A) to (C) of this paragraph related to the Shelf Registration Statement that do not affect the availability of the Resale Prospectus Supplement;

(c) if requested, furnish to each seller of Registrable Securities, the underwriters, and the sales or placement agent, if any, and counsel for each of the foregoing, a conformed copy of such registration statement and each amendment and supplement thereto (in each case, including all exhibits thereto and documents incorporated by reference therein) and such additional number of copies of such registration statement, each amendment, and supplement thereto (in such case without such exhibits and documents), the prospectus (including each preliminary prospectus) included in such registration statement, and the Resale Prospectus Supplements and all exhibits thereto and documents incorporated by reference therein, and such other documents as such seller, underwriter, agent, or counsel may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such seller; provided, that Buyer shall have no obligation to provide any document pursuant to this section that is available on the SEC’s EDGAR system;

(d) use commercially reasonable efforts to register or qualify such Registrable Securities under such securities or “blue sky” laws of such jurisdictions as the holders of Registrable Securities reasonably request and do any and all other acts and things that may be reasonably necessary or advisable to enable the holders of Registrable Securities to consummate the disposition in such jurisdictions of the Registrable Securities owned by such holders and keep such registration or qualification in effect for so long as the registration statement remains effective under the Securities Act (provided that Buyer shall not be required to (x) qualify generally to do business in any jurisdiction in which it would not otherwise be required to qualify but for this paragraph, (y) subject itself to taxation in any such jurisdiction in which it would not

2
