(i)   any item substantially similar in character or substance to any of the foregoing, which is permitted by GAAP to be accounted for in the calculation of Net Sales prevailing at the time and customary in the pharmaceutical industry at the time.

The transfer of any Covered Product by Parent, the Surviving Corporation or any of their respective Affiliates or Sublicensees to Parent, the Surviving Corporation or another of their respective Affiliates or Sublicensees, as the case may be, shall not be considered a Gross Sale or a Net Sale, but the resale of such Covered Product by any of the foregoing to third parties for commercial use shall be included in Net Sales.  In the case of any sale for value, such as barter or counter-trade, of any Covered Product, or part thereof, other than in an arm’s length transaction exclusively for cash, the Net Sales amount shall be deemed to be the Net Sales at which substantially similar quantities of such Covered Product are sold for cash in an arm’s length transaction in the relevant country.

If any Covered Product is sold as part of a Combination Product, the Net Sales for such Covered Product sold as part of a Combination Product, for the purposes of determining whether the First Net Sales Milestone or the Second Net Sales Milestone has been met in any period, shall be determined by multiplying the Net Sales of such Combination Product (replacing “Covered Product” with “Combination Product” in the definition of Net Sales above), during the applicable period, by the fraction, A/(A+B), where A is the average per unit sale price of such Covered Product when sold separately as a stand alone Covered Product in finished form in the country in which the Combination Product is sold and B is the average per unit sale price of the other active ingredients contained in the Combination Product when sold separately as stand alone products in finished form in the country in which the Combination Product is sold, in each case during the applicable period or, if sales of such stand alone Covered Product did not occur in such period, then in the most recent period in which arms length fair market sales of such Covered Product, as applicable, occurred.  If such average sale price cannot be determined for such Covered Product or any of the other active ingredients for the purposes of determining whether the First Net Sales Milestone or the Second Net Sales Milestone has been met in any period, the Net Sales amount shall be mutually agreed upon by the parties based on the relative value contributed by each component, such agreement not to be unreasonably withheld, conditioned or delayed.

Whenever conversion from any foreign currency shall be required for the purposes of calculating Net Sales, the amount of such sales in foreign currencies shall be converted into U.S. dollars using the exchange rate for the relevant month as determined by Parent’s then-current accounting policies (the “Monthly Rate”), such Monthly Rate being determined as the last price rate of exchange for such currencies on the last Business Day of the immediately preceding calendar month as published on Bloomberg page FXC (or such other publication as may be agreed to between Parent and the Equityholders’ Representative from time to time).

The Auditor will only be entitled to disclose to the Equityholders’ Representative (i) whether the Auditor believes it has been provided reasonable access to the relevant books and records to conduct an audit and inspection in accordance with this Section 2.9(d), and if not, the nature of any deficiencies in such access, (ii) any differences between the Auditor’s findings regarding Net Sales and GAAP Net Sales as determined by the Auditor, on the one hand, and the calculations of Net Sales and GAAP Net Sales set forth in any applicable Net Sales Statement and (iii) whether the First Net Sales Milestone and/or the Second Net Sales Milestone were met.  Such inspections may be made no more than once each calendar year and during normal business hours.  The books and records for any particular calendar year shall be subject to no more than one inspection, and in no event shall any inspection be initiated with respect to any calendar year more than two (2) years following the end of such calendar year.  The Auditor shall be obligated to execute a confidentiality agreement in form and substance reasonably satisfactory to Parent prior to commencing any such inspection.  Inspections conducted under this Section 2.9(d) shall be at the sole cost and expense of the Equityholders’ Representative; provided, however, that if by virtue of an inspection it is determined that Parent failed to notify the Equityholders’ Representative in a timely manner under Section 2.9(a) of the occurrence of the First Net Sales Milestone or the Second Net Sales Milestone, then Parent shall bear the cost and expense of such inspection.

(e) The Equityholders’ Representative and each Permitted Recipient (i) shall hold in confidence and shall not disclose to any other Person all information provided to it pursuant to Sections 2.9(c) and 2.9(d) except to the extent that such information can be shown to have been in the public domain through no fault of the Equityholders’ Representative, any

Permitted Recipient or any of their respective Affiliates and (ii) shall not use such information other than solely to assess the value of, the progress towards, and the probability of, achieving the Milestone Payments and to determine or enforce the Equityholders’ right to receive such Milestone Payments; provided, that the Equityholders’ Representative may disclose such information to (x) the employees, advisors and consultants of the Equityholders’ Representative to the same extent, and under the same conditions, as information may be disclosed to such Persons pursuant to the last sentence of Section 10.1(c) and (y) the Permitted Recipients so long as each such Permitted Recipient (A) is informed of the confidential nature of such information and (B) executes a confidentiality agreement with the Equityholders’ Representative regarding such information (1) that is comparable to and no less restrictive than the terms of this Section 2.9(e) with respect to the Equityholders’ Representative, (2) contains the acknowledgement and agreement referred to in the last sentence of this Section 2.9(e) and (3) to which Parent is made an express third party beneficiary.  At the request of Parent, the Equityholders’ Representative shall deliver, or cause to be delivered to Parent, true and correct copies of each such confidentiality agreement.  Any Permitted Recipient receiving such information shall not disclose such information to any Person, including to any prospective or current limited partner or other investor of such Permitted Recipient; provided, however, that a Permitted Recipient that is a venture capital fund may, (i) disclose such information to its auditors for purposes of enabling such auditors to confirm the reasonableness of the methodology utilized by such venture capital fund in valuing its expected return from the Merger; provided that such auditing firm agrees to enter into a confidentiality agreement regarding such information (A) that is comparable to and no less restrictive than the terms of this Section 2.9(e) with respect to the Equityholders’ Representative, (B) contains the acknowledgement and agreement referred to in the last sentence of this Section 2.9(e) and (C) to which Parent is made an express third party beneficiary and (ii) disclose to prospective and current limited partners the valuation such venture capital fund has placed on its expected return from the Merger and a general statement of the likelihood that the Milestone Payments will be received (e.g., a “high likelihood”, a “low likelihood”, “a greater or less than 50% likelihood”, etc.) (it being understood that in no event shall such general statement include any specifics regarding any Covered Product or the progress in achieving the Milestones (including details of the type included in Annual R&D Reports or the Net Sales Statements) that are not generally available publicly).  The Equityholders’ Representative acknowledges and agrees, and each Permitted Recipient receiving information of the type described above shall acknowledge and agree as part of the confidentiality agreement required to be executed by such Permitted Recipient, that (x) the information provided pursuant to Sections 2.9(c) and 2.9(d) may contain material non-public information concerning Parent and its Affiliates, (y) it shall comply with applicable securities laws regarding the trading of securities of Parent and its Affiliates while in possession of any such material non-public information, including any restrictions imposed by such laws prohibiting any Person who has received any such material non-public information from purchasing or selling securities of Parent and its Affiliates or from communicating such information to any other Person under circumstances in which it is reasonably foreseeable that such other Person is likely to purchase or sell such securities and (z) Parent is relying upon its compliance with the obligations under this Section 2.9(e) for purposes of compliance by Parent and its Affiliates with Regulation FD promulgated by the U.S. Securities and Exchange Commission (to the extent Parent or any of its Affiliates is subject to such regulation).

(f) Notwithstanding anything else in this Agreement to the contrary, in the event that the Company has not achieved the Initiation of the Phase III Clinical Trial Milestone on or before [**redacted**] other than as a result of a Fundamental Circumstance, then [**redacted**].

(g) Following the Closing, Parent, the Surviving Corporation and their respective Affiliates shall have the right, in their sole and absolute discretion, to direct and control the development, commercialization, manufacture, marketing, distribution and selling of the Covered Products in all respects, including the determination to test, develop, pursue, market, make any regulatory filings, including any NDA or MAA filing, or seek any Regulatory Approvals, including any marketing approvals in the United States or the European Union, with respect to, or make any strategic product portfolio decisions affecting, the Covered Products.  None of this Agreement or the other Transaction Documents or any other fact, circumstance or matter relating hereto or thereto (including the process of negotiation, execution and implementation hereof or thereof) shall be construed to impose upon Parent, the Surviving Corporation, or any of their respective Affiliates any express or implied obligation, duty or expectation to test, develop, pursue, market, make any regulatory filings or seek any Regulatory Approvals with respect to, or otherwise advance any Covered Product.

(h) During the period beginning at the Effective Time and ending on the date on which each Milestone Payment shall have been delivered to the Equityholders’ Representative or its designated agent for the benefit of the Equityholders, Parent, the Surviving Corporation and their respective Affiliates may not directly or indirectly consummate a Product Sale unless (i) Parent, the Surviving Corporation and their respective Affiliates made provision so that such acquirer assumes and succeeds to the obligations of Parent and the Surviving Corporation set forth in this Section 2.9 and (ii) prior to or simultaneously with the consummation of such Product Sale, such acquirer delivers to the Equityholders’ Representative an instrument of assumption for the benefit of the Equityholders effecting the assumption and succession described in the forgoing clause (i).

(i) If Parent, the Surviving Corporation or any of their respective Affiliates grants, directly or indirectly, a license to any Sublicensee in any jurisdiction pursuant to which such Sublicensee makes commercial sales of any Covered Product to any third party, then Parent shall ensure that such arrangement with such Sublicensee contains provisions requiring such Sublicensee to (i) deliver to Parent the information required by Parent to prepare and deliver to the Equityholders’ Representative the Net Sales Statements, (ii) keep accounts of all Net Sales and GAAP Net Sales, and deliver to Parent the information required by Parent to calculate Net Sales and GAAP Net Sales hereunder and (iii) if the Equityholders’ Representative initiates an inspection pursuant to Section 2.9(d), provide Parent with the right to request access for the Auditor to audit and inspect the books records of such Sublicensee in the same manner and to the same extent as required of an audit and inspection of Parent’s books and records pursuant to Section 2.9(d).

(j) Notwithstanding anything else in this Agreement to the contrary, if [**redacted**] of GAAP Net Sales for a given fiscal year exceeds Net Sales for such fiscal year, Net Sales for such fiscal year shall be deemed to be equal to [**redacted**].

(k) The right of each Equityholder to receive such Equityholder’s Contingent Allocation with respect to any Milestone Payment shall not be evidenced by any form of certificate or instrument, and does not represent any ownership or equity interest in the Surviving Corporation, Parent or any of their respective Affiliates and does not entitle any Equityholder to voting rights or rights to dividend payments. The right of each Equityholder to receive such Equityholder’s Contingent Allocation with respect to any Milestone Payment shall not be assignable or transferable except by (i) will, (ii) the Laws of intestacy, (iii) other operation of Law or (iv) if such Equityholder is a partnership or a limited liability company, pursuant to a

Permitted Disposition to one or more partners or members of such Equityholder or to one or more Affiliates of such Equityholder; provided that, in each case, written notice of such assignment and transfer shall be promptly delivered to each of Parent and the Equityholders’ Representative by the transferor or assignor (or such transferor’s or assignor’s estate), which notice shall expressly set forth the transferor or assignor and the transferee or assignee, the rights to which such transfer or assignment related and the effective date of such transfer; and, provided, further, that as a condition to such transfer or assignment, the parties to such transfer or assignment shall agree to provide to each of Parent and the Equityholders’ Representative, at their respective request, any additional evidence of the transfer or assignment that Parent or the Equityholders’ Representative, as the case may be, may reasonably request.  None of Parent, the Surviving Corporation or the Equityholders’ Representative shall give effect to any purported assignment or transfer made in contravention of this Section 2.9(k).  A “Permitted Disposition” means (a) a transfer or assignment by a Permitted Recipient that is a venture capital fund to its limited partners pursuant to a distribution that is made pro rata to such limited partners in accordance with the terms of such Permitted Recipient’s limited partnership or other governing documents and without the payment of any additional consideration therefor and (b) a transfer or assignment to a third party approved in writing in advance by Parent, such approval not to be unreasonably withheld, conditioned or delayed; provided that notwithstanding anything set forth in this Agreement, Parent shall have no obligation to approve any such transfer or assignment pursuant to the foregoing clause (b) if such transfer or assignment cannot, individually or taken together with any prior transfer or assignment and any potential future transfers or assignments and other facts and circumstances, be accomplished in a transaction that is, in Parent’s reasonable judgment, exempt from registration and qualification under, or would result in any other material adverse consequences under, U.S. federal and state securities laws or any other Law or would have an adverse Tax impact on Parent or its Affiliates (including the Surviving Corporation).

(l) For the purposes of calculating any Milestone Payment, the amount of cash in U.S. dollars set forth in the table in Section 2.9(a) under “Milestone Payment” opposite the applicable Milestone shall be reduced by the total of all Company Transaction Expenses of the type referred to in clause (i) of the definition thereof that would be payable if such amount set forth in the table in Section 2.9(a) were paid in full to the Equityholders’ Representative or its designated agent (calculated without duplication of any Company Transaction Expenses previously paid or deducted in determining the Merger Consideration or any prior Milestone Payment).

SECTION 2.10 Set Off Right.  Notwithstanding any provision of this Agreement to the contrary, the parties hereby acknowledge and agree that, in addition to any other right hereunder, Parent shall have the right, but not the obligation, from time to time to set off any indemnification payments alleged by Parent to be owed by the Equityholders to the Parent Indemnified Parties at such time pursuant to Article IX against any Milestone Payment that is owed and has not yet been paid; provided that the aggregate amount that Parent may set off as of a given time for indemnification payments owed by the Equityholders to the Parent Indemnified Parties pursuant to Sections 9.2(a) and 9.2(b) in respect of breaches of the Specified IP Representations and other non-Fundamental Representations shall not exceed the Specified Liability Limit as of such time; provided, further that for the avoidance of doubt, Parent’s right to set off indemnification payments owed by the Equityholders to the Parent Indemnified Parties pursuant to Sections 9.2(a) and 9.2(b) shall in each case be subject to Parent having delivered notice of such claim to the Equityholders’ Representative in accordance with the applicable provisions of Article IX within the applicable survival period specified in Section 9.1.  If it is finally resolved through negotiation or final, non-appealable decision of a court of competent jurisdiction that all or a portion of any amount set off by Parent was not entitled to be set off by

Parent, then Parent shall promptly pay the amount Parent was not entitled to set off to the Equityholders’ Representative or its designated agent plus interest accruing from and including the date such amount was withheld from the applicable Milestone Payment but excluding the date of payment at a rate per annum equal to (a) the prime rate as published in the Wall Street Journal, Eastern Edition in effect from time to time during such period plus (b) one percent (1%).

To the extent that an Equityholder of record has not delivered the Company Certificates representing all of such Equityholder’s shares of Company Capital Stock as of the Closing together with a properly completed and duly executed Letter of Transmittal on or prior to the Closing Date, then, promptly after the Effective Time, Parent shall instruct the Exchange Agent to mail to such Equityholder (A) a Letter of Transmittal

and (B) instructions for use in effecting the surrender of the Company Certificates in exchange for the portion of the Merger Consideration receivable in respect of such Company Certificates, and following the Effective Time, Parent shall pay or cause to be paid, promptly following surrender of a Company Certificate for cancellation to the Exchange Agent together with such Letter of Transmittal, properly completed and duly executed, and such other documents as may be required pursuant to such instructions, the aggregate Per Share Merger Consideration payable in respect of such Company Certificates pursuant to Section 2.6, subject to adjustment in accordance with Section 3.1(a) and withholding (if any) in accordance with Section 3.4.  All such payments shall be made out of the Exchange Fund to the extent it is then in existence, and the Exchange Fund shall not be used for any other purpose.  In the event of a transfer of ownership of shares of Company Capital Stock that is not registered in the transfer records of the Company, the portion of the Merger Consideration payable in respect of such shares of Company Capital Stock may be issued to a transferee if the Company Certificate representing such shares of Company Capital Stock is presented to the Exchange Agent, accompanied by any documents reasonably required to evidence and effect such transfer and by evidence that any applicable stock transfer Taxes have been paid.

(f) Lost, Stolen or Destroyed Company Certificates.  If any Company Certificate shall have been lost, stolen or destroyed, upon (i) the making of an affidavit of that fact by the Person claiming such Company Certificate to be lost, stolen or destroyed and (ii) the

execution and delivery to the Exchange Agent by such Person of a bond of indemnity in form and substance reasonably satisfactory to Parent and the Exchange Agent as indemnity against any claim that may be made against them with respect to such Company Certificate, the Exchange Agent shall, issue, in exchange for such lost, stolen or destroyed Company Certificate, the amount of cash, without interest, that such Person would have been entitled to receive had such Person surrendered such lost, stolen or destroyed Company Certificate to the Exchange Agent pursuant to Section 3.1(c), subject to withholding (if any) in accordance with Section 3.4.

(g) Treatment of Unsurrendered Securities.  No Per Share Contingent Consideration, Option Contingent Consideration or proceeds in respect of the Indemnity Escrow Fund or any Milestone Payments shall be paid pursuant to this Agreement or the Escrow Agreement to any Equityholder who has not surrendered his, her or its Company Certificates in accordance with Section 3.1(c) or has not delivered an Optionholder Letter in accordance with Section 3.1(d).  Parent shall timely provide to the Equityholders’ Representative a list of all Equityholders and/or Optionholders who have complied with the requirements of the preceding sentence prior to any Milestone Payment being delivered to the Equityholders’ Representative or its agent.

(h) No Liability.  Notwithstanding anything to the contrary in this Section 3.1, neither the Company, Parent nor the Surviving Corporation shall be liable to any Person for any amount properly paid to a public official pursuant to any abandoned property, escheat or similar Law.

SECTION 3.2 Dissenting Shares.  Notwithstanding any provision of this Agreement to the contrary, if required by the DGCL, but only to the extent required thereby, shares of Company Capital Stock which are issued and outstanding immediately prior to the Effective Time and which are held by holders of such shares of Company Capital Stock who have properly exercised appraisal rights with respect thereto in accordance with the DGCL (the “Dissenting Shares”) shall not be exchangeable for the right to receive the amount payable with respect to such Company Capital Stock pursuant to Section 2.6, and holders of such shares of Company Capital Stock shall be entitled to receive payment of the appraised value of such shares of Company Capital Stock, subject to withholding (if any) in accordance with Section 3.4, in accordance with the provisions of the DGCL unless and until such holders fail to perfect or effectively withdraw or lose their rights to appraisal and payment under the DGCL. If, after the Effective Time, any such holder fails to perfect or effectively withdraws or loses such right, such shares of Company Capital Stock shall thereupon be treated as if they had been converted into and to have become exchangeable for, at the Effective Time, the right to the amount payable with respect to such Company Capital Stock pursuant to Section 2.6, without any interest thereon.  The Company shall give Parent and Merger Sub prompt notice of any written demands for appraisal, withdrawals of demands for appraisal and any other related instruments received by the Company, and Parent shall have the opportunity and right to direct all negotiations and proceedings with respect to such demands and the exercise of such appraisal rights under the provisions of the DGCL.  The Company shall not, except with the prior written consent of Parent, voluntarily make any payment with respect to any demands for appraisal or settle or offer to settle any such demand.

SECTION 3.3 No Further Ownership Rights in Shares of Company Capital Stock; Closing of Company Transfer Books.  At and after the Effective Time, each holder of Company Capital Stock shall cease to have any rights as a stockholder of the Company, except for, in the case of a holder of Company Capital Stock (other than shares to be cancelled pursuant to Section 2.6(a) or Dissenting Shares), the right to surrender his or her Company Certificate in

exchange for payment of the amount payable with respect to such Company Capital Stock pursuant to Section 2.6 or, in the case of a holder of Dissenting Shares, to perfect his or her right to receive payment for his or her shares of Company Capital Stock pursuant to the DGCL, and no transfer of shares of Company Capital Stock shall be made on the stock transfer books of the Surviving Corporation.  At the Effective Time, the stock transfer books of the Company shall be closed, and no transfer of shares of Company Capital Stock shall thereafter be made.  If, after the Effective Time, Company Certificates are presented to the Exchange Agent, they shall be cancelled and exchanged as provided for in this Agreement.

SECTION 3.4 Withholding Rights.

(a) Parent, the Surviving Corporation, the Exchange Agent and the Escrow Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any Equityholder such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any applicable provision of state, local or foreign Tax Law; provided, however, (i) before making any such deduction or withholding (other than deduction or withholding in respect of (A) federal income tax withholding under Section 1441 or 1442 of the Code with respect to any amounts treated as interest under Section 483 or 1274 of the Code, (B) Taxes with respect to Option Payments and payments with respect to Company Restricted Stock held by a current or former employee of any Acquired Company who has not timely filed an election under Section 83(b) of the Code, and (C) backup withholding, Parent or the Surviving Corporation, as applicable, shall give the Equityholders’ Representative notice of the intention to make such deduction or withholding (such notice, which shall include the authority, basis and method of calculation for the proposed deduction or withholding, shall be given at least a commercially reasonable period of time before such deduction or withholding is required, in order for the Equityholders to obtain, if available, reduction of or relief from such deduction or withholding, and the Equityholders’ Representative shall use commercially reasonable efforts to promptly provide copies of such notice to the Equityholders), (ii) Parent, the Surviving Corporation, the Exchange Agent and the Escrow Agent, as applicable, shall cooperate with the Equityholders to the extent reasonable in efforts to obtain, if available, reduction of or relief from such deduction or withholding (other than with respect to a Company Option held by an Employee Optionholder or Company Restricted Stock held by a current or former employee of any Acquired Company) and (iii) Parent, the Surviving Corporation, the Exchange Agent and the Escrow Agent, as applicable, shall timely remit to the appropriate Governmental Authority any and all amounts so deducted or withheld and timely file all Tax Returns and provide to the Equityholders’ Representative such information statements and other documents required to be filed or provided under applicable Tax Law.  To the extent that amounts are so withheld by Parent, the Surviving Corporation, the Exchange Agent and the Escrow Agent in accordance with the foregoing, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Equityholder in respect of which such deduction and withholding was made by Parent, the Surviving Corporation, the Exchange Agent and the Escrow Agent.

(b) The parties hereto acknowledge and agree that, for U.S. federal income tax purposes, a portion of each Milestone Payment received by each Equityholder (other than any Equityholder as to whom the receipt of such Milestone Payment is treated as the receipt of compensation for such purposes) may be treated as imputed interest to the extent required under Sections 483 and 1274 of the Code.

(a) From and after the Effective Time, Parent shall cause the Surviving Corporation to (i) indemnify and hold harmless each present and former director and officer of each Acquired Company (collectively, the “Company Indemnified Parties”), against any and all Damages incurred or suffered by any of the Company Indemnified Parties in connection with any Liabilities or any Action, whether civil, criminal, administrative or investigative, arising out of or pertaining to matters existing or occurring at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, to the fullest extent that the relevant Acquired Company would have been permitted under applicable Law and under the Company Certificate of Incorporation and Company Bylaws (or equivalent organizational documents of the relevant Acquired Company), as the case may be, in each case as in effect on the date of this Agreement (but in each case, subject to the limitations on the Surviving Corporation’s ability to indemnify its

directors and officers under Section 145 of the DGCL), to indemnify such Company Indemnified Parties and (ii) advance reasonable expenses of counsel as incurred by any Company Indemnified Party in connection with any matters for which such Company Indemnified Party is entitled to indemnification from Parent pursuant to this Section 6.7(a) to the fullest extent permitted under applicable Law or, if greater, under the Company Certificate of Incorporation and Company Bylaws (or equivalent organizational documents of the relevant Acquired Company), in each case, as in effect on the date of this Agreement; provided, however, that the Company Indemnified Party to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately and finally determined by a court of competent jurisdiction and all rights of appeal have lapsed that such Company Indemnified Party is not entitled to indemnification under applicable Law, the Company Certificate of Incorporation and Company Bylaws (or equivalent organizational documents of the relevant Acquired Company), and pursuant to this Section 6.7(a); and provided further that Parent and the Surviving Corporation shall not be obligated to pay expenses of more than one counsel for all Company Indemnified Parties in any single Action unless a conflict of interest precludes the effective representation of more than one Company Indemnified Party with respect to such Action.

(b) At or prior to the Effective Time, the Company shall purchase a prepaid directors’ and officers’ liability insurance policy or policies (i.e., “tail coverage”), which policy or policies shall cover those persons who are currently covered by the Company’s directors’ and officers’ liability insurance policy for an aggregate period of not less than six (6) years from the Effective Time with respect to claims arising from facts or events that occurred on or before the Closing Date, including with respect to the transactions contemplated by this Agreement, the premium for which shall be treated as a Company Transaction Expense.

(c) The terms and provisions of this Section 6.7 are intended to be in addition to the rights otherwise available to the Company Indemnified Parties by applicable Law, charter, bylaw or agreement, and shall operate for the benefit of, and shall be enforceable by, the Company Indemnified Parties and their respective heirs and representatives, each of whom is an intended third party beneficiary of this Section 6.7.

SECTION 6.8 Employee Benefit Matters.

(a) For purposes of determining eligibility to participate, vesting and entitlement to benefits where length of service is relevant under any benefit plan or arrangement (excluding vesting under any equity incentive plan and benefit accrual under any defined benefit plan) of Parent, the Surviving Corporation or any of their respective Subsidiaries, Company Employees as of the Effective Time shall receive service credit for service with the Acquired Companies to the same extent such service credit was granted under the Company Benefit Plans, subject to offsets for previously accrued benefits and administered in a manner that does not provide for duplication of benefits.  Parent and the Surviving Corporation shall (i) waive all limitations as to preexisting conditions exclusions and waiting periods with respect to participation and coverage requirements applicable to the Company Employees under any welfare benefit plans that such employees may be eligible to participate in after the Effective Time, other than limitations or waiting periods that are already in effect with respect to such employees and that have not been satisfied as of the Effective Time under any welfare benefit plan maintained for the Company Employees immediately prior to the Effective Time and (ii) provide each Company Employee with credit for any co-payments and deductibles paid prior to the Effective Time in satisfying any applicable deductible or out-of-pocket requirements for the plan year that includes the Closing Date under any welfare plans (other than a Company Benefit Plan) that such employees are eligible to participate in after the Effective Time.

(b) For a period of twelve (12) months following the Closing, Parent shall provide (or cause the Surviving Corporation or another Affiliate of Parent to provide) to employees of the Surviving Corporation or any other Affiliate of Parent who were employees of any Acquired Company immediately prior to the Effective Time (“Continuing Employees”) base compensation, bonus opportunities, severance benefits and employee welfare and retirement benefits (other than equity-based compensation arrangements) (such compensation and benefits, collectively, “Employee Benefits”) which are no less favorable in the aggregate than the Employee Benefits provided to the Continuing Employees of the Acquired Companies immediately prior to the Closing.  For the avoidance of doubt, payments and benefits to any individual (including an employee of any Acquired Company) who provides consulting services to Parent or any of its Affiliates following the Effective Time shall be set forth in an individual consulting agreement between such individual and Parent or the Surviving Corporation.

(c) Nothing contained herein shall be construed as requiring, and the Company shall take no action that would have the effect of requiring, Parent, the Surviving Corporation or any Acquired Company to continue any specific Company Benefit Plan or to continue the employment of any specific Person.  The provisions of this Section 6.8 are for the sole benefit of Buyer and the Company and nothing in this Section 6.8, expressed or implied, is intended or shall be construed to constitute an amendment of any Company Benefit Plan or any plan maintained Parent or its Affiliate (or an undertaking to amend any such plan) or other compensation and benefits plan maintained for or provided to Acquired Company employees, including Continuing Employees,  prior to or following the Closing Date.

(d) This Section 6.8 shall be binding upon and inure solely to the benefit of each of the parties to this Agreement, and nothing in this Section 6.8, expressed or implied, is intended to confer upon any other Person any rights or remedies of any nature whatsoever under or by reason of this Section 6.8.  Without limiting the foregoing, no provision of this Section 6.8 shall create any third party beneficiary rights in any current or former employee, director or consultant of any Acquired Company.

SECTION 6.9 Provision Respecting Legal Representation.  Each of the parties to this Agreement hereby agrees, on its own behalf and on behalf of its directors, members, partners, officers, employees and Affiliates, that Xxxxxx & Xxxxxxx LLP may serve as counsel to each and any holder of Company Capital Stock and their respective Affiliates (individually and collectively, the “Holder Group”), on the one hand, and the Company, 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, Xxxxxx & Xxxxxxx LLP (or any successor thereof) may serve as counsel to the Holder Group or any director, member, partner, officer, employee or Affiliate of the Holder Group or the Equityholders’ Representative, 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 and each of the parties hereto hereby consents thereto and waives any conflict of interest arising therefrom, and each of such parties shall cause any Affiliate thereof to consent to waive any conflict of interest arising from such representation.

SECTION 6.10 Tax Matters.

(a) Transfer Taxes.  All Transfer Taxes shall be borne by Parent.  Parent hereby agrees to file in a timely manner all necessary documents (including, but not limited to, all Tax Returns) with respect to all such amounts for which Parent is so liable.  Parent shall provide

the Equityholders’ Representative with evidence satisfactory to the Equityholders’ Representative that such Transfer Taxes have been paid by Parent.  Parent shall pay all such Transfer Taxes without deduction or withholding from any consideration or amounts payable under this Agreement.

(b) FIRPTA Certificate.  At or prior to the Closing, the Company shall deliver to Parent a certification prepared in accordance with Treasury Regulations Section 1.1445-2(c)(3) and a notice prepared in accordance with Treasury Regulations Section 1.897-2(h) certifying that interests in the Company are not U.S. real property interests (it being understood that Parent shall be authorized to deliver a copy of such certification to the Internal Revenue Service after the Closing on behalf of the Company).

(a) the failure of an Acquired Company, Merger Sub or Parent, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it pursuant to this Agreement which would reasonably be expected to result in any condition to the obligations of any party to effect the Merger or any other transaction contemplated by this Agreement not to be satisfied;

(b) any notice or other communication from any Person alleging that the consent of such Person is or may be required in connection with the transactions contemplated by this Agreement;

(c) any notice or other communication from any Governmental Authority in connection with the transactions contemplated by this Agreement; and

SECTION 6.12 Termination of Related Party Agreements and Accounts.  All agreements and accounts between an Acquired Company and each Related Party (other than (i) agreements and accounts between Acquired Companies, (ii) employment, severance, indemnification or other similar arrangements with directors, officers or employees of any Acquired Company (and amounts payable in connection therewith) and (iii) the Standard Exclusive License Agreement with Sublicensing Terms, dated May 9, 2008, between the Company and University of Florida Research Foundation, Inc.) are listed in Schedule 6.12.  All such agreements (other than those listed in the parenthetical in the preceding sentence) shall be terminated immediately prior to the Closing (and all obligations and Liabilities thereunder shall be canceled without payment or any further Liability on the part of the Company or any other Acquired Company), and all such accounts shall be canceled, paid or otherwise settled and terminated immediately prior to the Closing.

SECTION 6.13 Section 280G Matters.  To the extent that (i) any “disqualified individual” (as such term is defined for purposes of Section 280G of the Code) of an Acquired Company would be entitled to any payment or benefit as a result of the transactions contemplated

by this Agreement and (ii) such payment or benefit would or could potentially constitute a “parachute payment” under Section 280G of the Code or could reasonably be expected to result in the imposition of any excise Tax imposed under Section 4999 of the Code, prior to the Closing:

(a) the Company shall use its commercially reasonable efforts to obtain a binding written waiver by such “disqualified individual” (each, an “Excess Parachute Waiver”) of any portion of such parachute payment as exceeds three times less one dollar such individual’s “base amount” within the meaning of Section 280G(b)(3) of the Code (collectively, the “Excess Parachute Payments”) to the extent such Excess Parachute Payments are not subsequently approved pursuant to a stockholder vote in accordance with the requirements of Section 280G(b)(5)(B) of the Code and Regulations § 1.280G-1 thereunder (the “280G Shareholder Approval Requirements”);

(b) the Company shall use its commercially reasonable efforts to obtain stockholder approval in a manner that satisfies the 280G Shareholder Approval Requirements in respect of the Excess Parachute Payments payable to all such “disqualified individuals”;

(c) the Company shall provide all required disclosure to all persons entitled to vote under Section 280G(b)(5)(B)(ii) of the Code and shall hold a vote of stockholders in the manner intended to satisfy the 280G Shareholder Approval Requirements; and

SECTION 9.2 Right to Indemnification. Subject to the limitations set forth in this Article IX, from and after the Effective Time, each of the Equityholders, severally and in proportion to each such Equityholder’s respective Aggregate Pro Rata Share of the Total Consideration as of such time, shall hold harmless and indemnify each of Merger Sub, the Surviving Corporation, Parent and their respective officers, directors, employees, agents, representatives and Affiliates (the “Parent Indemnified Parties”) against any Damages actually incurred as a result of (a) any breach or inaccuracy of any representation or warranty set forth in Article IV (disregarding any exception or qualification as to materiality or Material Adverse Effect set forth therein), (b) any breach or inaccuracy of any representation or warranty set forth in Article IV as of the Closing Date as if such representation or warranty had been made as of the Closing Date except for such representations and warranties that address matters only as of a particular time, which need only be accurate as of such time (disregarding any exception or qualification as to materiality or Material Adverse Effect set forth therein), (c) any breach or violation of any covenant or agreement of the Company set forth in this Agreement, (d) any Closing Cash, Closing Debt, Company Transaction Expense or Past Due Payable that was improperly accounted for or not accounted for in the determination of the Merger Consideration or, in the case of any Company Transaction Expense, any Milestone Payment, but, in each case, only to the extent that such improper accounting or lack of accounting resulted in an overpayment of the Merger Consideration or such Milestone Payment, (e) the exercise of dissenters’ rights or rights of appraisal by any holder or former holder of Company Capital Stock (it being understood that the Parent Indemnified Parties’ Damages in respect of such exercise shall be equal to the amount, if any, by which (i) the aggregate payment to such holder in respect of such holder’s Dissenting Shares, together with all reasonable costs and expenses (including reasonable attorneys’ fees, costs and expenses) incurred by the Parent Indemnified Parties in respect of such holder’s exercise, exceeds (ii) the product of the number of such holder’s Dissenting Shares and the price per share set forth on Section 9.2 of the Company Disclosure Schedule), (f) any actual or alleged breach of fiduciary duty by an Equityholder or any present or former director or officer of any Acquired Company prior to the Closing (including, for the avoidance of doubt, all Damages actually incurred by any Acquired Company or any other Parent Indemnified Party arising from the indemnification of, the advancement or reimbursement of expenses to, or the payment of insurance proceeds (including self-insured retention or deductible amounts, costs and expenses of pursuing claims and related increases in insurance premiums) to, any such Person based upon any actual or alleged breach of fiduciary duty of such Person prior to the Closing), (g) any actual or alleged breach by the Company of the Amended and Restated Investors’ Rights Agreement dated as of June 3, 2010 by and among the Company, the investors listed on the

Schedule of Investors attached thereto and the University of Florida Research Foundation, Inc. (as such agreement may have been amended, modified or supplemented), and  (h) any inaccuracy in the Consideration Allocation Schedule, including to the extent any Equityholder is entitled to receive any amounts in connection with the Merger (in such Equityholder’s capacity as an Equityholder) in excess of the amounts indicated on the Consideration Allocation Schedule.

SECTION 9.3 Limitations on Liability.

(a) From and after the Effective Time, except as otherwise provided in this Agreement (including Parent’s right of set-off pursuant to Section 2.10 and the provisions of this Agreement that provide for remedies including injunctive relief or specific performance), the right of the Parent Indemnified Parties to be indemnified from the Indemnity Escrow Fund pursuant to this Article IX shall be the sole and exclusive remedy for any matter arising under or related to this Agreement or the transactions contemplated hereby, other than any claims relating to the breach of a Fundamental Representation, a Specified IP Representation, a Specified Covenant or claims arising out of fraud or intentional misrepresentation of the Company or any Person acting on the Company’s behalf; provided that in no event shall any Equityholder be liable to the Parent Indemnified Parties for Damages (i) in excess of such Equityholder’s Aggregate Pro Rata Share of such Damages as of such time, (ii) in excess of the portion of the Total Consideration actually received by such Equityholder as of such time or (iii) with respect to Damages arising from or relating to breaches of any representations or warranties of the Company set forth in this Agreement other than the Fundamental Representations, in excess of the Specified Liability Limit as of such time.  Except as provided with respect to the Equityholders in the immediately preceding sentence, no current or former stockholder, director, officer, employee, affiliate or advisor of the Company shall have any Liability of any nature to any Parent Indemnified Party with respect to any matter arising under or related to this Agreement or the transactions contemplated hereby.  Notwithstanding anything to the contrary contained in this Section 9.3, nothing herein shall limit or otherwise affect Parent’s rights or remedies in respect of any breach by the Equityholders’ Representative of Sections 2.9(a), 2.9(d), 2.9(e), 2.9(k), 3.4 or 10.1(c) or any breach or inaccuracy of any of the Equityholders’ Representative’s representations or warranties set forth in Section 10.1(e).

(b) Notwithstanding anything to the contrary contained in this Agreement, except for Damages resulting from a breach of a Fundamental Representation, a Specified IP Representation or fraud or intentional misrepresentation, no Equityholder shall be liable to a Parent Indemnified Party in respect of any indemnification hereunder pursuant to Section 9.2(a) or (b) except to the extent that the aggregate amount (without duplication) of Damages of the Parent Indemnified Parties exceeds $750,000 (the “Deductible”), in which event the Parent Indemnified Parties shall, subject to the other limitations contained herein, be entitled to be indemnified only against the portion of Damages in excess of the Deductible.  Without limiting Parent’s right of set-off pursuant to Section 2.10, any amounts payable by the Equityholders to a Parent Indemnified Party pursuant to Section 9.2 shall be paid solely and exclusively from the Indemnity Escrow Fund in accordance with the terms of the Escrow Agreement, except with respect to the breach of a Fundamental Representation, a Specified IP Representation, a Specified Covenant (in which case the Indemnity Escrow Fund must first be exhausted before recovery can be made against any Equityholder) or fraud or intentional misrepresentation.  Notwithstanding the foregoing, except for Damages resulting from a breach of a Fundamental Representation, a Specified IP Representation or fraud or intentional misrepresentation, no claim for indemnification may be made pursuant to Section 9.2(a) or (b) unless the amount of such claim (or series of related claims arising from the same underlying facts) shall exceed $25,000, and if the amount of such claim(s) does not exceed such amount, the amount of such claim(s) shall not

be taken into account in determining whether or not or to the extent to which the Deductible has been exceeded.

(c) Without limiting the effect of any other limitation contained in this Article IX for purposes of computing the amount of any Damages incurred by Parent under this Article IX, there shall be deducted (i) an amount equal to the amount of any Tax Benefit actually realized by Parent or any of its Affiliates in connection with such Damages and (ii) an amount equal to the amount of any insurance proceeds, indemnification payments, contribution payments or reimbursements actually received (net of costs of enforcement, deductibles and retro-premium adjustments) by Parent or any of its Affiliates in respect of such Damages (it being understood that Parent and any of its Affiliates shall use commercially reasonable efforts to obtain such proceeds, payments or reimbursements).  To the extent that a claim for indemnification by Parent or Merger Sub hereunder relates to a Liability incurred by the Company and there is a specific accrual on the Current Balance Sheet in respect of such Liability, then the determination of Damages in respect of such claim shall be net of such accrual. If Parent or any of its Affiliates actually realizes a Tax Benefit on account of such Damages after an indemnification payment has been made to it, Parent or its Affiliates, as the case may be, shall promptly pay (up to the amount of indemnification payment previously made to Parent or its Affiliates with respect to such Damages) to the Equityholders’ Representative the amount of such Tax Benefit at such time or times as and to the extent that such Tax Benefit is actually realized by Parent or its Affiliates, to the extent not previously offset against Damages paid by the Equityholders. For purposes hereof, “Tax Benefit” shall mean any refund or credit of Taxes to be paid or reduction in the amount of Taxes which otherwise would be owed by Parent or its Affiliates, as applicable, actually realized by Parent or its Affiliates in the taxable year in which the relevant Damages were incurred or the subsequent taxable year.

SECTION 9.4 Claims and Procedures.

(a) If Parent determines in good faith that any Parent Indemnified Party has a bona fide claim for indemnification pursuant to this Article IX, Parent may deliver to the Equityholders’ Representative a certificate signed by any officer of Parent (any certificate delivered in accordance with the provisions of this Section 9.4(a), an “Officer’s Claim Certificate”):

(i) stating that a Parent Indemnified Party has a claim for indemnification pursuant to this Article IX;

(ii) to the extent possible, containing a good faith non-binding, preliminary estimate of the amount to which such Parent Indemnified Party claims to be entitled to receive, which shall be the amount of Damages such Parent 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 Parent) the material facts known to the Parent Indemnified Party giving rise to such claim.

No delay in providing such Officer’s Claim Certificate prior to the Expiration Date shall affect a Parent Indemnified Party’s rights hereunder, unless (and then only to the extent that) the Equityholders are materially prejudiced thereby.

(b) At the time of delivery of any Officer’s Claim Certificate to the Equityholders’ Representative, if the Indemnity Escrow Account has not been released in accordance with the terms of the Escrow Agreement, a duplicate copy of such Officer’s Claim Certificate shall be delivered to the Escrow Agent by or on behalf of Parent (on behalf of itself or any other Parent Indemnified Party).

(c) If the Equityholders’ Representative in good faith objects to any claim made by Parent in any Officer’s Claim Certificate, then the Equityholders’ Representative shall deliver a written notice (a “Claim Dispute Notice”) to Parent during the thirty (30) day period commencing upon receipt by the Equityholders’ Representative of the Officer’s Claim Certificate (such period, the “Claim Response Period”).  The Claim Dispute Notice shall set forth in reasonable detail the basis for the dispute of any claim made by Parent in the Officer’s Claim Certificate.  If the Equityholders’ Representative does not deliver a Claim Dispute Notice to Parent prior to the expiration of such thirty (30) day period, then (i) each claim for indemnification set forth in such Officer’s Claim Certificate shall be deemed to have been conclusively determined in Parent’s favor for purposes of this Article IX on the terms set forth in the Officer’s Claim Certificate and (ii) if cash remains in the Indemnity Escrow Fund, then Parent may direct the Escrow Agent to deliver cash from the Escrow Fund to Parent in accordance with this Section 9.4 and the Escrow Agreement.

(d) If the Equityholders’ Representative delivers a Claim Dispute Notice within the Claim Response Period, then Parent and the Equityholders’ Representative shall attempt in good faith to resolve any such objections raised by the Equityholders’ Representative in such Claim Dispute Notice.  If Parent and the Equityholders’ Representative agree to a resolution of such objection, then a memorandum setting forth the matters conclusively determined by Parent and the Equityholders’ Representative shall be prepared and signed by both parties and, if cash remains in the Indemnity Escrow Fund, promptly delivered to the Escrow Agent directing the Escrow Agent to distribute cash from the Indemnity Escrow Fund in accordance with the terms of such memorandum.

(e) If no such resolution can be reached during the forty-five (45) day period following Parent’s receipt of a given Claim Dispute Notice, then upon the expiration of such forty-five (45) day period, either Parent or the Equityholders’ Representative may bring suit to resolve the objection in accordance with Sections 10.12 and 10.13.  Upon any such resolution, Parent and the Equityholders’ Representative shall promptly direct the Escrow Agent to act in accordance with such decision and distribute cash from the Indemnity Escrow Fund in accordance therewith.

SECTION 9.5 Defense of Third-Party Claims.

(a) Upon receipt by any Parent Indemnified Party seeking to be indemnified pursuant to Section 9.2 of notice of any actual claim, demand, suit, action, arbitration, investigation, inquiry or proceeding that has been brought or asserted by a third party against such Parent Indemnified Party and that may be subject to indemnification hereunder (a “Third-Party Claim”), the Parent Indemnified Party shall promptly deliver an Officer’s Claim Certificate to the Equityholders’ Representative indicating the nature of such Third-Party Claim and the stated basis therefor and the amount of Damages claimed pursuant to such Third-Party Claim, to the extent known.

(b) (i) The Equityholders’ Representative shall have ten (10) days after receipt of the Officer’s Claim Certificate notice of a given Third-Party Claim to elect, at its

option, to assume the defense of any such Third-Party Claim if the Equityholders’ Representative (A) acknowledges that the Damages resulting from such Third-Party Claim are Damages for which the Equityholders must indemnify or hold harmless the Parent Indemnified Party pursuant to Section 9.2 and (B) furnishes the Parent Indemnified Party with evidence that the Equityholders have adequate resources to defend the Third-Party Claim; provided that the Equityholders’ Representative shall not be entitled to assume or maintain control of the defense of any Third-Party Claim if (1) the Third-Party Claim relates to or arises in connection with any criminal Action, (2) the Third Party Claims seeks an injunction or equitable relief for other than monetary damages against any Parent Indemnified Party, (3) the Equityholders have failed or are failing to prosecute or defend vigorously the Third-Party Claim or (4) the amount of the Third-Party Claim, if determined in favor of the claimant, would reasonably be expected to result in Damages, together with all other then-outstanding claims for indemnification hereunder, that would exceed the remaining available amount in the Indemnity Escrow Fund.  (ii) If the Equityholders’ Representative assumes the defense of a Third-Party Claim: (A) the attorneys’ fees, other professionals’ and experts’ fees and court or arbitration costs incurred by the Equityholders’ Representative in connection with defending such Third-Party Claim shall be payable by the Equityholders, (B) the Parent Indemnified Party shall be entitled to monitor and participate in such defense at its sole expense (except as provided in the following sentence), (C) the Parent Indemnified Party shall make available to the Equityholders’ Representative all books, records and other documents and materials of any Acquired Company that the Equityholders’ Representative reasonably considers necessary or desirable for the defense of such Third-Party Claim, (D) the Parent Indemnified Party shall otherwise cooperate in good faith as reasonably requested by the Equityholders’ Representative in the defense of such Third-Party Claim, (E) the Parent Indemnified Party shall not admit any Liability with respect to such Third-Party Claim, (F) the Equityholders’ Representative shall not enter into any agreement providing for the settlement or compromise of such Third-Party Claim or the consent to the entry of a judgment with respect to such Third-Party Claim without the prior written consent of Parent Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed) and (G) the Parent Indemnified Party shall not enter into any agreement providing for the settlement or compromise of such Third-Party Claim or the consent to the entry of a judgment with respect to such Third-Party Claim without the prior written consent of Equityholders’ Representative (which consent shall not be unreasonably withheld, conditioned or delayed).  (iii) The Parent Indemnified Party shall have the right to employ separate counsel in such Third-Party Claim and participate in such defense thereof, but the fees and expenses of such counsel shall be at the expense of the Parent Indemnified Party, provided, however, that the Parent Indemnified Party shall be entitled, at the Equityholders’ cost, risk and expense, to retain one firm of separate counsel of its own choosing (along with any required local counsel) if (w) the Equityholders’ Representative and the Parent Indemnified Party so mutually agree, (x) the Equityholders’ Representative fails within a reasonable time to retain counsel reasonably satisfactory to the Parent Indemnified Party, (y) the Parent Indemnified Party shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Equityholders or (z) the named parties in any such proceeding (including any impleaded parties) include both the Equityholders and the Parent Indemnified Party and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them.

SECTION 9.6 Subrogation.  To the extent that a Parent Indemnified Party is entitled to indemnification pursuant to this Article IX, the Equityholders’ Representative shall be entitled (on behalf of the Equityholders) to exercise, and shall be subrogated to, any rights and remedies (including rights of indemnity, rights of contribution and other rights of recovery) that the Parent Indemnified Party or any of the Parent Indemnified Party’s Subsidiaries or other Affiliates may have against any other Person with respect to any Damages, circumstances or

matter to which such indemnification is directly or indirectly related.  The Parent Indemnified Party shall take such actions as the Equityholders’ Representative may reasonably request for the purpose of enabling the Equityholders’ Representative to perfect or exercise the right of subrogation of the Equityholders’ Representative under this Section 9.6.

SECTION 9.7 Characterization of Indemnification Payments.  The parties agree that any indemnification payments made pursuant to this Article IX shall be treated for all Tax purposes as an adjustment to the purchase price unless otherwise required by Law.

ARTICLE X.

GENERAL PROVISIONS

SECTION 10.1 Equityholders’ Representative.

(a) Appointment.  By virtue of the adoption of this Agreement by the Company’s stockholders, and without further action of any Company stockholder, each Equityholder shall be deemed to have irrevocably constituted and appointed Shareholder Representative Services LLC (and by execution of this Agreement it hereby accepts such appointment) to act as the Equityholders’ Representative and as the sole agent and attorney-in-fact for and on behalf of the Equityholders (in their capacity as such), with full power of substitution, to act in the name, place and stead of each Equityholder with respect to Article II, Article III, Article IX and the Escrow Agreement and the taking by the Equityholders’ Representative of any and all actions and the making of any decisions required or permitted to be taken by the Equityholders’ Representative under Article II, Article III, Article IX and the Escrow Agreement and to accept on behalf of each Equityholder service of process and any notices required to be served on the Equityholders.  The power of attorney granted in this Section 10.1(a) is coupled with an interest and is irrevocable, may be delegated by the Equityholders’ Representative and shall survive the death or incapacity of each Equityholder.  Such agency may be changed by the holders of a majority in interest of the Escrow Fund from time to time (including in the event of the death, disability or other incapacity of an Equityholders’ Representative that is an individual), and any such successor shall succeed the Equityholders’ Representative as Equityholders’ Representative hereunder.  Neither the removal of, nor the appointment of a successor, Equityholders’ Representative shall affect in any manner the validity or enforceability of any actions taken or agreements, understandings or commitments entered into by the prior Equityholders’ Representative, which shall continue to be effective and binding on the Equityholders.  For the avoidance of doubt, any compromise or settlement of any matter by the Equityholders’ Representative hereunder shall be binding on, and fully enforceable against, all Equityholders.  No bond shall be required of the Equityholders’ Representative.

(b) Limitation on Liability.  The Equityholders’ Representative (in its capacity as such) shall not be liable to any Person for any act of the Equityholders’ Representative taken in good faith and arising out of or in connection with the acceptance or administration of its duties under this Agreement and the Escrow Agreement (it being understood that any act done or omitted pursuant to the advice of legal counsel shall be conclusive evidence of such good faith), except to the extent any Liability, loss, damage, penalty, fine, cost or expense is actually incurred by such Person as a result of the gross negligence, willful misconduct or bad faith of the Equityholders’ Representative.  The Equityholders’ Representative shall not be liable for, and shall be indemnified by the Equityholders for, and to the extent available shall be entitled to draw against the Equityholders’ Representative Fund at any time and from time to time for, any Liability, loss, damage, penalty, fine, cost or expense (“Representative Losses”) incurred by the Equityholders’ Representative while acting in good faith and arising out of or in connection

with the acceptance or administration of its duties under this Agreement and the Escrow Agreement, except to the extent that any such Liability, loss, damage, penalty, fine, cost or expense is the proximate result of the gross negligence, willful misconduct or bad faith of the Equityholders’ Representative. If not paid directly to the Equityholders’ Representative by the Equityholders or satisfied by the funds in the Equityholders’ Representative Fund, any such Representative Losses may be recovered by the Equityholders’ Representative from (i) the amounts in the Indemnity Escrow Fund otherwise distributable to the Equityholders pursuant to the terms hereof and the Escrow Agreement at the time of distribution in accordance with written instructions delivered by the Equityholders’ Representative to the Escrow Agent and (ii) any Milestone Payments actually payable to the Equityholders; provided that while this Section 10.1(b) allows the Equityholders’ Representative to be paid from the Escrow Fund and the Milestone Payments, this Section 10.1(b) shall not relieve the Equityholders from their obligation to promptly pay such Representative Losses as such Representative Losses are suffered or incurred, nor shall it prevent the Equityholders’ Representative from seeking any remedies available to it at law or otherwise. The Equityholders’ Representative shall be permitted, in its sole discretion, to engage a third-party payment agent for the purposes of the distributing funds to the Equityholders as required by this Agreement and shall be entitled to be reimbursed by the Equityholders for the costs thereof, including by utilizing funds from the Equityholders’ Representative Fund.  The Equityholders’ Representative shall be the administrator of the Equityholders’ Representative Fund and shall have authority to draw against the Equityholders’ Representative Fund in accordance with the preceding sentences of this Section 10.1(b).

(c) Access.  Subject to the provisions of Sections 2.9(c), 2.9(d) and 2.9(e), from and after the Effective Time, Parent shall cause the Surviving Corporation to provide the Equityholders’ Representative with reasonable access to information about the Surviving Corporation and the reasonable assistance of the officers and employees of Parent and the Surviving Corporation for purposes of performing its duties and exercising its rights under this Agreement, provided, that the Equityholders’ Representative shall treat confidentially any nonpublic information about the Surviving Corporation; provided that the foregoing shall not prevent the Equityholders’ Representative from disclosing such information to enforce any rights or defend any claims hereunder so long as such disclosure is relevant to the enforcement of such rights or defense of such claims and is only disclosed in formal proceedings related thereto and provided that the Equityholders’ Representative shall give Parent as much notice thereof as reasonably practicable, makes reasonable efforts to obtain confidential treatment of such information and discloses no more than is legally required.  Notwithstanding anything in this Agreement to the contrary, the Equityholders’ Representative may disclose information (x) to the extent required by Law, (y) to Permitted Recipients who are bound by obligations of confidentiality with respect to such information that are at least as restricted as those imposed on Permitted Recipients pursuant to Section 2.9(e) and (z) to employees, advisors or consultants of the Equityholders’ Representative, in the case of the foregoing clauses (y) and (z), who have a need to know such information; provided that (i) each such Person referred to in clause (z) is informed of the confidential nature of such information and is bound by obligations of confidentiality to the Equityholders’ Representative and (ii) the Equityholders’ Representative shall be responsible for the action by any such Person that would constitute a breach of this Section 10.1(c) if taken by the Equityholders’ Representative.

(d) Actions of the Equityholders’ Representative.  From and after the Effective Time, a decision, act, consent or instruction of the Equityholders’ Representative shall constitute a decision of all Equityholders and shall be final, binding and conclusive upon each Equityholder, and the Escrow Agent and the Parent Indemnified Parties shall be entitled to deal exclusively with the Equityholders’ Representatives on all matters relating to this Agreement and

the Escrow Agreement, and may rely upon any decision, act, consent or instruction of the Equityholders’ Representative as being the decision, act, consent or instruction of each Equityholder.  The Parent Indemnified Parties are hereby relieved from any Liability to any Person for any acts done by them in accordance with any such decision, act, consent or instruction of the Equityholders’ Representative.

(e) Representations and Warranties.  The Equityholders’ Representative, solely in its capacity as the representative of the Equityholders, represents and warrants to Parent and Merger Sub, as of the date hereof and as of the Closing Date, as follows:

(i) the Equityholders’ Representative is a limited liability company duly organized, validly existing and in good standing under the Laws of Colorado, and has all requisite limited liability company power and authority and all material Permits required to carry on its business in all material respects as currently conducted;

(ii) the execution and delivery of this Agreement by the Equityholders’ Representative, and the performance by the Equityholders’ Representative of its obligations hereunder, have been duly authorized by all necessary corporate action on the part of the Equityholders’ Representative;

(iii) this Agreement has been duly executed and delivered by the Equityholders’ Representative and, assuming due authorization, execution and delivery by the other parties to this Agreement, this Agreement constitutes a legally valid and binding obligation of the Equityholders’ Representative, enforceable against the Equityholders’ Representative in accordance with its terms, except as enforceability may be limited by principles of public policy, and subject to (A) the effect of any applicable Law of general application relating to bankruptcy, reorganization, insolvency, or moratorium or similar Laws affecting creditors’ rights and relief of debtors generally and (B) the effect of rules of Law and general principles of equity, including rules of Law and general principles of equity governing specific performance, injunctive relieve and other equitable remedies (regardless of whether such enforceability is considered in a proceeding in equity or at Law); and

(iv) the execution and delivery of this Agreement by the Equityholders’ Representative, and the performance by the Equityholders’ Representative of its obligations hereunder and under the Escrow Agreement do not and will not (A) conflict with or result in a violation of the organizational documents of the Equityholders’ Representative, (B) to its knowledge, violate any Law applicable to the Equityholders’ Representative or (C) require any consent or approval that has not been given or other action that has not been taken by any Person under any Contract binding upon the Equityholders’ Representative.

SECTION 10.2 Expenses.  Except as otherwise expressly provided in this Agreement, all costs and expenses (including all fees and disbursements of counsel, financial advisors and accountants) incurred in connection with the negotiation and preparation of this Agreement, the performance of the terms of this Agreement and the consummation of the transactions contemplated by this Agreement, shall be paid by the respective party incurring such costs and expenses, whether or not the Closing shall have occurred.

SECTION 10.3 Costs and Attorneys’ Fees.  Subject to the limitations set forth herein, including Article IX, in the event that any action, suit or other proceeding is instituted concerning or arising out of this Agreement, the prevailing party shall recover all of such party’s

costs and reasonable attorneys’ fees incurred in connection with each and every such action, suit or other proceeding, including any and all appeals and petitions therefrom.

SECTION 10.5 Public Announcements.  Unless otherwise required by applicable Law, any listing agreement with any U.S. or U.K. securities exchange or share market, or any listing authority including the U.K. Listing Authority, no party to this Agreement shall make any public announcements in respect of this Agreement or the transactions contemplated by this Agreement, or otherwise communicate with any news media regarding this Agreement or the transactions contemplated by this Agreement, without the prior written consent of the other parties to this Agreement.  If a public statement is required to be made pursuant to applicable Law, any listing agreement with any U.S. or U.K. securities exchange or share market, or any listing authority including the U.K. Listing Authority, the parties shall consult with each other, to the extent permitted by such applicable Law, agreement or authority and to the extent reasonably practicable, in advance as to the contents and timing thereof.

SECTION 10.6 Interpretation.  The Article and Section headings in this Agreement are for convenience of reference only and shall not be deemed to alter or affect the meaning or interpretation of any provision of this Agreement.  References to Articles, Sections, Schedules or Exhibits in this Agreement, unless otherwise indicated, are references to Articles, Sections, Schedules and Exhibits of or to this Agreement.  The parties to this Agreement have participated jointly in the negotiation and drafting of this Agreement.  In the event an ambiguity or question of intent or interpretation arises with respect to any term or provision of this Agreement, this Agreement shall be construed as if drafted jointly by the parties to this Agreement, and no presumption or burden of proof shall arise favoring or disfavoring any party to this Agreement by virtue of the authorship of any of the terms or provisions of this Agreement.  Any reference to any federal, state, county, local or foreign statute or Law shall be deemed also to refer to all rules and regulations promulgated thereunder, unless the context requires otherwise.  For all purposes of and under this Agreement, (a) the word “including” shall be deemed to be immediately followed by the words “without limitation,” (b) words (including defined terms) in the singular shall be deemed to include the plural and vice versa, (c) words of one gender shall be deemed to include the other gender as the context requires, (d) the terms “hereof,” “herein,” “hereto,” “herewith” and any other words of similar import shall, unless otherwise stated, be construed to refer to this Agreement as a whole (including the Company Disclosure Schedule, the other Schedules and Exhibits to this Agreement) and not to any particular term or provision of this Agreement, unless otherwise specified and (e) unless otherwise defined in this Agreement, accounting terms shall have the respective meanings assigned to them in accordance with GAAP applied on a consistent basis.

SECTION 10.7 Severability.  In the event that any one or more of the terms or provisions contained in this Agreement or in any other certificate, instrument or other document referred to in this Agreement, shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other term or provision of this Agreement or any other such certificate, instrument or other document referred to in this Agreement, and the parties to this Agreement shall use their commercially reasonable efforts to substitute one or more valid, legal and enforceable terms or provisions into this Agreement which, insofar as practicable, implement the purposes and intent of this Agreement.  Any term or provision of this Agreement held invalid or unenforceable only in part, degree or within certain jurisdictions shall remain in full force and effect to the extent not held invalid or unenforceable to the extent consistent with the intent of the parties as reflected by this Agreement.  To the extent permitted by applicable Law, each party waives any term or provision of Law which renders any term or provision of this Agreement to be invalid, illegal or unenforceable in any respect.

SECTION 10.8 Entire Agreement.  This Agreement (including the Company Disclosure Schedule, the other Schedules and the Exhibits to this Agreement) and the Confidentiality Agreement constitute the entire agreement of the parties to this Agreement with respect to the subject matter of this Agreement and the Confidentiality Agreement, and supersede all prior agreements and undertakings, both written and oral, among the parties to this Agreement with respect to the subject matter of this Agreement and the Confidentiality Agreement, except as otherwise expressly provided in this Agreement.

SECTION 10.9 Assignment.  Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties to this Agreement (whether by operation of law or otherwise) without the prior written consent of the other parties to this Agreement, and any purported assignment or other transfer without such consent shall be void and unenforceable, except that Parent or Merger Sub may transfer or assign its rights and obligations under this Agreement, in whole or from time to time in part, to (a) one or more of their respective Affiliates at any time and (b) after the Effective Time, to any Person; provided, that such transfer or assignment shall not relieve Parent or Merger Sub of its obligations hereunder or enlarge, alter or change any obligation of any other party hereto.  Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of and be enforceable by the parties to this Agreement and their respective successors and assigns.

SECTION 10.10 No Third-Party Beneficiaries.  This Agreement is for the sole benefit of the parties to this Agreement and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any legal or equitable right, benefit or remedy of any nature whatsoever under or by reason of this Agreement, except for (a) the Company Indemnified Parties under Section 6.7, (b) the Parent Indemnified Parties under Article IX and (c) the Company on behalf of the Equityholders to pursue damages (including claims for damages based on loss of the economic benefits of the transaction to the Equityholders) in the event of Parent’s or Merger Sub’s breach of this Agreement prior to the Closing Date (whether or not the Agreement has been terminated pursuant to Article VIII), which right is hereby expressly acknowledged and agreed by Parent and Merger Sub.  The third-party beneficiary rights referenced in clause (c) of the preceding sentence may be exercised only by the Company (on behalf of the Equityholders as their agent) through actions expressly approved by the Company’s Board of Directors, and no Equityholder whether purporting to act in its capacity as a Equityholder or purporting to assert any right (derivatively or otherwise) on behalf of the Company, shall have any right or ability to exercise or cause the exercise of any such right.

SECTION 10.11 Waivers and Amendments.  This Agreement may be amended or modified only by a written instrument executed by all of the parties to this Agreement.  Any failure of the parties to this Agreement to comply with any obligation, covenant, agreement or condition in this Agreement may be waived by the party entitled to the benefits thereof only by a written instrument signed by the party granting such waiver.  No delay on the part of any party to this Agreement in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any waiver on the part of any party to this Agreement of any right, power or privilege hereunder operate as a waiver of any other right, power or privilege hereunder, nor shall any single or partial exercise of any right, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder.  Unless otherwise provided, the rights and remedies provided for in this Agreement are cumulative and are not exclusive of any rights or remedies which the parties to this Agreement may otherwise have at law or in equity.  Whenever this Agreement requires or permits consent by or on behalf of a party, such consent shall be given in writing in a manner consistent with the requirements for a waiver of compliance as set forth in this Section 10.11.

SECTION 10.12 Governing Law; Consent to Jurisdiction.  This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware applicable to contracts executed in and to be performed entirely within such State.  Each of the parties to this Agreement hereby irrevocably and unconditionally submits, for itself and its assets and properties, to the exclusive jurisdiction of any Delaware State court, or Federal court of the United States of America sitting within the State of Delaware, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement, the agreements delivered in connection with this Agreement, or the transactions contemplated hereby or thereby, or for recognition or enforcement of any judgment relating thereto, and each of the parties to this Agreement hereby irrevocably and unconditionally (a) agrees not to commence any such action or proceeding except in such courts, (b) agrees that any claim in respect of any such action or proceeding may be heard and determined in such Delaware State court or, to the extent permitted by Law, in such Federal court, (c) waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any such action or proceeding in any such Delaware State or Federal court and (d) waives, to the fullest extent permitted by Law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such Delaware State or Federal court.  Each of the parties to this Agreement hereby agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law.  Each of the parties to this Agreement hereby irrevocably consents to service of process in the manner provided for notices in Section 10.4.  Nothing in this Agreement shall affect the right of any party to this Agreement to serve process in any other manner permitted by applicable Law.

SECTION 10.13 Waiver of Jury Trial.  EACH PARTY TO THIS AGREEMENT ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE, IT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE AGREEMENTS DELIVERED IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.  EACH PARTY TO THIS AGREEMENT CERTIFIES AND ACKNOWLEDGES THAT (a) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE

EITHER OF SUCH WAIVERS, (b) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVERS, (c) IT MAKES SUCH WAIVERS VOLUNTARILY AND (d) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 10.13.

SECTION 10.14 Exclusivity of Representations and Warranties.  It is the explicit intent and understanding of each of the parties to this Agreement that no party to this Agreement, nor any of their respective Affiliates, representatives or agents, is making any representation or warranty whatsoever, oral or written, express or implied, other than those set forth in this Agreement (as qualified by the Company Disclosure Schedule), and none of the parties to this Agreement is relying on any statement, representation or warranty, oral or written, express or implied, made by another party to this Agreement or such other party’s Affiliates, representatives or agents, except for the representations and warranties set forth in this Agreement.

SECTION 10.15 Equitable Remedies.  Each of the parties to this Agreement acknowledges and agrees that the other parties to this Agreement would be irreparably damaged in the event that any of the terms or provisions of this Agreement are not performed in accordance with their specific terms or otherwise are breached.  Therefore, notwithstanding anything to the contrary set forth in this Agreement, each of the parties to this Agreement hereby agrees that the other parties to this Agreement shall be entitled to obtain an injunction or injunctions to prevent breaches of any of the terms or provisions of this Agreement, and to enforce specifically the performance by such first party under this Agreement, and each party to this Agreement hereby agrees to waive the defense in any such suit that the other parties to this Agreement have an adequate remedy at law and to interpose no opposition, legal or otherwise, as to the propriety of injunction or specific performance as a remedy, and hereby agrees to waive any requirement to post any bond in connection with obtaining such relief.  The equitable remedies described in this Section 10.15 shall be in addition to, and not in lieu of, any other remedies at law or in equity that the parties to this Agreement may elect to pursue.

SECTION 10.16 Counterparts.  This Agreement may be executed in one or more counterparts, each of which when executed shall be deemed to be an original, but all of which taken together shall constitute one and the same agreement.
