(b) By executing this Agreement, each Stockholder hereby acknowledges and agrees that all outstanding Company Options held by such Stockholder that are not exercised as of immediately prior to the Closing shall, as of the Closing, be deemed automatically cancelled and no longer represent the right to acquire Company Common Shares or any other securities of the Company or any of its Affiliates, and, subject to the provisions of Section 1.4(a) governing the treatment of Company Options, all agreements between the Company and such Stockholder relating to such Company Options shall be deemed terminated in their entirety, void and of no further force or effect.

(c) By executing this Agreement, each Stockholder hereby acknowledges and agrees that all outstanding Company Warrants held by such Stockholder that are not exercised as of immediately prior to the Closing shall, as of the Closing, be deemed automatically cancelled and no longer represent the right to acquire Company Common Shares or any other securities of any of the Company or any of its Affiliates, and all agreements between the Company and such Stockholder relating to such Company Warrants shall be deemed terminated in their entirety, void and of no further force or effect.

Section 1.6 Net Debt Adjustment .

(a) No later than five (5) Business Days prior to the Closing Date, the Company shall deliver to the Purchaser a calculation of the estimated Net Debt of the Company at and as of immediately prior to the Closing, which sets forth a good faith estimate of the Net Debt as of such time (the “ Estimated Net Debt ”). The Estimated Net Debt calculation shall be prepared by the Company in accordance with GAAP consistently applied and in accordance with the preparation of the Company Financial Statements. The Purchaser and its Representatives, including the Purchaser’s independent accountants, shall have access to all work papers of the Company and its Representatives, including its independent accountants, relating to the Estimated Net Debt. If the Purchaser disputes the Estimated Net Debt (or any portion thereof) prior to the Closing, then the Purchaser and the Company shall negotiate in good faith to resolve any such dispute at or prior to the Closing. If the Estimated Net Debt is a negative number, the absolute value of the difference between zero and the Estimated Net Debt as reflected, if any, shall be referred to herein as the “ Excess Net Debt .” For avoidance of doubt, if the Estimated Net Debt is a positive number, then no Net Debt-related adjustment shall be made to the Closing Consideration.

(b) As promptly as practicable, but no later than 90 days after the Closing Date, the Purchaser shall cause to be prepared and delivered to the Stockholders’ Representative a calculation of the Net Debt of the Company at and as of immediately prior to the Closing, which shall set forth the Purchaser’s good faith calculation of the Net Debt as of such time (the “ Final Net Debt ”). The Final Net Debt calculation shall be prepared by the Purchaser or its Representatives in accordance with GAAP consistently applied and in accordance with the preparation of the Company Financial Statements.

(c) If the Stockholders’ Representative disagrees with the Purchaser’s calculation of the Final Net Debt delivered pursuant to Section 1.6(b), then the Stockholders’ Representative may, within 45 days after delivery of the Final Net Debt calculation, deliver a written statement (the “ Statement of Objection ”) to the Purchaser disagreeing with such calculation that: (i) specifies the Stockholders’ Representative’s calculation of the Final Net Debt, (ii) indicates each item or amount in the calculation of the Net Debt disputed by the Stockholders’ Representative, and (iii) sets forth in detail the Stockholders’ Representative’s grounds for disputing each individual item or amount in the Final Net Debt calculation. The Stockholders’ Representative may only deliver one Statement of Objection to the Purchaser, and the Stockholders’ Representative shall not raise any disagreements with the Final Net Debt calculation other than the disagreements set forth in the Statement of Objection, nor shall the Stockholders’ Representative assert any claims that the value of any item or amount is greater or less than the value claimed in the Statement of Objection. Failure by the Stockholders’ Representative to deliver a Statement of Objection within such 45 day period shall be deemed to constitute acceptance by the Stockholders’ Representative of the Purchaser’s calculation of the Final Net Debt, and shall be final and binding upon, and non-appealable by, the Purchaser, the Stockholders’ Representative and, for the avoidance of doubt, the Stockholders.

(d) If a Statement of Objection shall be delivered to the Purchaser pursuant to Section 1.6(c), the Purchaser and the Stockholders’ Representative shall, during the 15 days following

4

such delivery, use commercially reasonable, good faith efforts to reach agreement on the disputed items or amounts in order to determine, as may be required, the amount of the Final Net Debt. If the Purchaser and the Stockholders’ Representative are able to reach such agreement during such 15 day period, the Final Net Debt, with such changes as may have been previously agreed in writing by the Purchaser and the Stockholders’ Representative, shall be final and binding upon, and non-appealable by, the Purchaser, the Stockholders’ Representative and, for the avoidance of doubt, the Stockholders.

(e) If the Purchaser and the Stockholders’ Representative are unable to reach such agreement during such 15 day period, they shall promptly and jointly retain a firm of independent accountants of internationally recognized standing reasonably satisfactory to the Stockholders’ Representative and the Purchaser (who shall not have any material relationship with the Stockholders’ Representative or the Purchaser) (the “ Accounting Referee ”) and cause the Accounting Referee promptly to review this Agreement and such disputed amounts. The Accounting Referee shall be instructed to resolve such disputes within 45 days of retention of the Accounting Referee. The Accounting Referee shall address only those matters in dispute and may not allow a value greater than the greatest value for such item claimed by either party or smaller than the smallest value for such item claimed by either party. The Accounting Referee shall deliver to the Purchaser and the Stockholders’ Representative, as promptly as practicable but in no event later than 45 days after retention of the Accounting Referee, a report setting forth such calculation. Such report shall be final and binding upon, and non-appealable by, the Purchaser, the Stockholders’ Representative and, for the avoidance of doubt, the Stockholders. The cost of such review and report shall be borne by the Purchaser, on the one hand, and the Stockholders (payable by the Stockholders’ Representative on their behalf, with pro rata contribution by the Stockholders based upon their Consideration Percentage), on the other, in inverse proportion as the Purchaser and the Stockholders’ Representative (on behalf of the Stockholders), respectively, may prevail on the matters resolved by the Accounting Referee, which proportionate allocation shall also be determined by the Accounting Referee and be included in the Accounting Referee report.

(f) The Purchaser and the Stockholders’ Representative agree that they will, and agree to cause their respective independent accountants to, cooperate and assist in the preparation of the calculation of the Final Net Debt, including making available, to the extent necessary, books, records, work papers and personnel.

(g) If the Final Net Debt is less (that is, more in the negative direction) than the Estimated Net Debt, the Purchaser shall be entitled to recover, pursuant to the Escrow Agreement, such number of the Escrow Shares as is equal to the product obtained by multiplying: (i) the quotient obtained by dividing: (A) the amount by which the Final Net Debt is less (that is, more in the negative direction) than the Estimated Net Debt (such amount, the “ Net Debt Adjustment Amount ”) by (B) the Closing Per Share Price, by (ii) the Proration Factor, within five (5) Business Days from when the Final Net Debt has become final, binding and non-appealable in accordance with Section 1.6(c), (d) or (e); provided , however , that the Purchaser shall in no event be entitled to recover any of the Escrow Shares pursuant to this Section 1.6(g) if the Final Net Debt is a positive number or if the Final Net Debt is a number greater (that is, less in the negative direction) than the Estimated Net Debt.

Section 1.7 Escrow . At the Closing, the Purchaser shall withhold the Initial Escrow Shares and deliver such Initial Escrow Shares to Wilmington Trust N.A., as escrow agent (the “ Escrow Agent ”), to be held by the Escrow Agent as collateral to secure the rights of the Purchaser pursuant to Section 1.6(a) and of the Indemnified Parties under ARTICLE X. The Escrow Shares shall be held pursuant to the provisions of an escrow agreement to be entered into among the Purchaser, the Escrow Agent and the Stockholders’ Representative substantially in the form of E XHIBIT  B hereto (the “ Escrow Agreement ”).

5

On the date that is six months after the Closing Date, any of the Escrow Shares not previously released by the Escrow Agent as of such date shall be released by the Escrow Agent (the “ Escrow Period ”); provided , however , that in the event any Indemnified Party has made a claim under ARTICLE X prior to the end of the Escrow Period, then, in accordance with and subject to the terms and conditions of the Escrow Agreement, the Escrow Period shall continue (and the Escrow Agent will continue to hold such number of the Escrow Shares in escrow as is equal to the quotient obtained by dividing: (i) any claimed amounts by (ii) the Closing Per Share Price, rounded up to the nearest whole share, until such claim is fully and finally resolved. By virtue of the execution of this Agreement by a Stockholder, without any further act of any Stockholder, such Stockholder shall be deemed to have consented to and approved (A) the use of the Escrow Shares as collateral to secure the rights of the Purchaser pursuant to Section 1.6(a) in the manner set forth herein and in the Escrow Agreement, (B) the use of the Escrow Shares as collateral to secure the rights of the Indemnified Parties under ARTICLE X in the manner set forth herein and in the Escrow Agreement, and (C) the appointment of the Stockholders’ Representative as the representative under the Escrow Agreement of the Stockholders under this Agreement and as the attorney-in-fact and agent for and on behalf of such Stockholder.

Section 1.8 Exercise of Company Options and Company Warrants Pre-Closing . In the event that any holder of a Company Option or Company Warrant exercises such Company Option or Company Warrant prior to the Closing (each such holder, an “ Exercising Holder ”), to the extent such Exercising Holder is not already a party to this Agreement as a Stockholder, the Company shall cause such Exercising Holder to execute a joinder signature to this Agreement whereby such Exercising Holder shall agree to become a party to, and bound by, the provisions of this Agreement, in each case in substantially the form of E XHIBIT C hereto (each, a “ Joinder Agreement ”).

Section 1.9 Non-Accredited Investors . Notwithstanding any provisions of this Agreement to the contrary, in the event the Purchaser or the Company believes in its reasonable discretion that a Stockholder entitled to receive consideration upon the acceleration of a Company Option in accordance with Section 1.4(a) is not an “accredited investor” as defined in Rule 501(a) of Regulation D promulgated under the Securities Act, in connection with the cancellation of such Company Option, the Purchaser shall pay (or cause to be paid) to the holder of such Company Option, in the form of cash only (and not in the form of Purchaser Common Stock), an amount equal to (a) the number of Company Common Shares subject to the Company Option multiplied by (b) the positive amount, if any, by which the Fair Market Value (as defined in the Company Stock Option Plan) of a Company Common Share on the date of the Closing exceeds the exercise price of such Company Option. The cash amount payable in respect of a Company Option pursuant to this Section 1.9 shall be the sole consideration payable in connection with the cancellation of any such option, and no further consideration shall be payable to the holder thereof in respect of such Company Option.

Section 1.10 Definitions . Capitalized terms used in this Agreement but not otherwise defined in this Agreement shall have the meanings set forth in E XHIBIT A hereto.

Such Stockholder thus acknowledges that he may discover facts in addition to or different from those that he now knows or believes to be true with respect to the subject matter of this release, but that it is his intention to fully and finally settle and release any and all claims released hereby, known or unknown, suspected or unsuspected, which now exist, or heretofore existed, or may hereafter exist, and without regard to subsequent discovery or existence of such additional or different facts. Such Stockholder acknowledges that the release of unknown claims was separately bargained for, constitutes separate consideration for, and was a key element of the Agreement and was relied upon by the Purchaser in entering into the Agreement.

Section 5.13 Termination of Certain Agreements . Prior to the Closing, the Company shall terminate, or cause to be terminated, the agreements and arrangements set forth on S CHEDULE 5.13 (the “ Excluded Contracts ”), such that the Company shall not have any liability following the Closing related to such Excluded Contracts. Each such termination shall include a release of the Company, as applicable, from any and all liabilities and obligations arising out of, or related to, such Excluded Contract.

Section 5.14 Purchaser Representative . During the Pre-Closing Period, the Company shall facilitate the appointment of a “purchaser representative” as defined by Rule 501(h) of Regulation D under the Securities Act, by each Stockholder who is not an “accredited investor” as defined in Rule 501(a) of Regulation D promulgated under the Securities Act to the extent such appointment is required to comply with Regulation 506 of Regulation D and other applicable Laws in connection with the issuance of shares of Purchaser Common Stock contemplated by this Agreement.

Section 5.15 Employees .

(a) Immediately prior to the Closing, the Company shall, in full compliance with all applicable laws and legal requirements, terminate the employment of the Employees set forth on S CHEDULE 5.15( A )(1) . The Purchaser shall have no liability with respect to the employment or termination by the Company of any such employees, including any liability or obligation for or with respect to accrued benefits, continuing benefits, severance or otherwise, and the Company shall be responsible for all such liabilities and obligations. Prior to or at the Closing, the Company or one of its Affiliates shall offer employment to, and enter into an offer letter with, each of the Persons set forth on S CHEDULE 5.15( A )(2) in the form of E XHIBIT D-1 or E XHIBIT D-2 hereto (collectively, the “ Offer Letters ”) with such Offer Letters to be effective as of the Closing Date. Such Offer Letters shall supersede any existing employment agreement or arrangement between the Company and the Persons set forth on S CHEDULE 5.15( A )(2) , and the Purchaser shall have no liability with respect to any existing employment agreement or arrangement between such employees and the Company, including any

51

liability or obligation for or with respect to accrued benefits, continuing benefits, severance or otherwise, and the Company shall be responsible for all such liabilities and obligations.

(b) Immediately prior to the Closing Date, the Company shall terminate all of the Employee Plans set forth on S CHEDULE  5.15( B ) (except as otherwise specified on such Schedule with respect to the applicable plan), and Purchaser shall provide the Company with sufficient funds, and the Company shall pay the expenses of terminating such Employee Plans.

(c) Prior to the Closing, the Company shall provide Purchaser with a schedule, in a form reasonably acceptable to the Purchaser, setting forth, as of the Closing Date, the vacation pay each Employee has accrued but not used. On the Closing Date, the Purchaser shall provide the Company with sufficient funds, and the Company shall pay to each Employee who is terminated immediately prior to the Closing under Section 5.15(a) all amounts owed to such individual (including, but not limited to, vacation pay and final wages). Following the Closing, the Company shall not have any outstanding obligations to such Employees.

(d) From and after the Closing, the Company shall assume or retain, as the case may be, and be solely responsible for all known and unknown liabilities arising under, resulting from or relating to the Employee Plans or the Company’s employment of or termination of the Employees, whether incurred, accrued or arising before, on or after the Closing, including without limitation, any liability attributable to a breach of the representations in Section 2.16 and Section 2.17. In accordance with Treasury Regulation Section 54.4980B-9, Q&A 7, the Company shall be and is solely responsible for COBRA coverage for all M&A qualified beneficiaries (determined in accordance with Treasury Regulation Section 54.4980B-9, Q&A 4) including, but not limited to, with respect all Employee Plans. The Company shall ensure that the Purchaser and its Affiliates do not have any obligation under COBRA with respect to any Employees. The Company shall take all steps that may be necessary, including arranging for continued group health plan coverage for the COBRA statutory coverage period for each M&A qualified beneficiary, to ensure that such COBRA continuation coverage is available to such individuals and to ensure that the provisions of Treasury Regulation Section 54.4980B-9, Q&A 8(c) do not become applicable at any time, and to prevent the Purchaser from becoming by operation of such regulation, section or otherwise, a “successor employer” for purposes of COBRA coverage. For purposes of this Agreement, “qualified beneficiary,” “M&A qualified beneficiaries,” “group health plan” and “qualifying event” shall have the meanings ascribed thereto in Section 4980B of the Code and the related regulations.

(e) Notwithstanding anything to the contrary in this Section 5.15, the provisions of this Section 5.15 are for the sole benefit of the Company and the Purchaser and neither this Agreement nor any action by the Company or the Purchaser shall be deemed to create any third party beneficiary rights in any person or organization, including any Employee (including any beneficiary or dependent thereof) of the Company or the Purchaser, or any ERISA Affiliate, and no person or organization other than the Parties to this Agreement shall have any rights to enforce any provision hereof, including any provision pertaining to any benefits that may be provided, directly or indirectly, under any employee benefit plan, including the Employee Plans. The parties expressly acknowledge and agree that (i) this Agreement is not intended to create a Contract between the Purchaser, the Company or any ERISA Affiliate, on the one hand, and any Employee or any employee of any ERISA Affiliate, on the other hand, and no Employee and no employee of any ERISA Affiliate may rely on this Agreement as the basis for any breach of contract claim against the Purchaser, the Company, or any ERISA Affiliate, (ii) nothing in this Agreement shall be deemed or construed to require the Purchaser, the Company, or any ERISA Affiliate to continue to employ any particular Employee or any employee of any ERISA Affiliate for any

period of time after the Closing, (iii) nothing in this Agreement shall be deemed or construed to limit the Company’s or the Purchaser’s right to terminate the employment of any Employee during any period after the Closing, and (iv) nothing in this Agreement shall modify or amend any Employee Plan set forth on Section 2.17 of the Disclosure Schedule or any other agreement, plan, program or document unless this Agreement explicitly states that the provision “amends” such Employee Plan or other agreement, plan, program or document.

(f) None of the Company, the Stockholders or any of their Representatives shall make any communication to employees of the Company regarding any 401(k), group health, life insurance, disability, accidental death and dismemberment insurance, equity incentive plans or employee stock purchase plans maintained by the Purchaser or any of its Affiliates or any compensation or benefits to be provided after the Closing Date without the advance approval of the Purchaser.

Section 5.16 Operation of the Purchaser’s Business .

(a) During the Pre-Closing Period, the Purchaser shall: (a) ensure that the Purchaser conducts its business and operations in the ordinary course of business consistent with past practice; (b) use best efforts to ensure that the Purchaser preserves intact its current business organization and maintain its relations and goodwill with all suppliers, customers, landlords, creditors, licensors, licensees, employees, consultants and other Persons having business relationships with the Purchaser; and (c) maintain the books, records and financial statements of the Purchaser in accordance with GAAP and consistent with past practice.

Section 10.2 Indemnification Procedure .

(a) Promptly following receipt by an Indemnified Party of notice by a third-party (including any Governmental Body) of any complaint, dispute or claim or the commencement of any audit, investigation, action or proceeding with respect to which such Indemnified Party may be entitled to indemnification pursuant to this Agreement (a “ Third-Party Claim ”), or upon realization of a Loss by an Indemnified Party for which the Indemnified Party is entitled to indemnification under this ARTICLE X, such Indemnified Party shall provide written notice thereof to the Stockholders’ Representative; provided, however , that the failure to so notify the Stockholders’ Representative shall relieve the Indemnifying Party from liability under this ARTICLE X with respect to such Third-Party Claim only if, and only to the extent that, such failure to so notify the Stockholders’ Representative materially prejudices the rights and defenses otherwise available to the Indemnifying Party with respect to such Third-Party Claim. The

63

Indemnifying Party shall have the right, upon written notice from the Stockholders’ Representative delivered to the Indemnified Party within ten (10) days thereafter assuming full responsibility for any Losses resulting from such Third-Party Claim, to assume the defense of such Third-Party Claim, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of the fees and disbursements of such counsel; provided , however , that the Indemnifying Party shall not have the right to assume the defense of any Third-Party Claim that (i) affects any Intellectual Property Rights that the Company owns or has a right to use in the conduct of its business as currently conducted and as proposed to be conducted by the Company as of the Closing and by the Purchaser after the Closing, (ii) is asserted directly by or on behalf of any Person that is a supplier or a customer of the Company, the Indemnified Party or their Affiliates, (iii) seeks an injunction or other equitable relief against the Indemnified Party or its Affiliates, (iv) involves a finding of any violation of Law or other wrongdoing by the Indemnified Party, the Company or their Affiliates, (v) relates to or arises in connection with any criminal proceeding, action, indictment, allegation or investigation, or (vi) does not seek only monetary damages and, in the case of this clause (vi), the Indemnified Party reasonably believes an adverse determination with respect to the Third-Party Claim would be detrimental to or materially injure the reputation or future business prospects of the Indemnified Party. In the event, however, that the Indemnifying Party declines or fails to assume the defense of such Third-Party Claim on the terms of this Section 10.2(a) or to employ counsel reasonably satisfactory to the Indemnified Party, in either case within such ten (10) day period, or thereafter defaults in continuing to defend the Indemnified Party, then any Losses shall include the reasonable fees and disbursements of counsel for the Indemnified Party as incurred. In addition, Losses shall include, as incurred, the reasonable fees and disbursements of counsel for the Indemnified Party: (A) that are incurred prior to the date the Indemnifying Party effectively assumes control of such defense, (B) if the Indemnified Party employs separate counsel due to the Indemnified Party being advised by counsel that a reasonable likelihood exists of a conflict of interest between the Indemnified Party and the Indemnifying Party, (C) if the Indemnified Party employs separate counsel because there are one or more legal or equitable defenses available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party, or (D) if the Indemnified Party employs separate counsel because such audit, investigation, action or proceeding involves, or could have a material effect on, any matter beyond the scope of the indemnification or defense obligations of the Indemnifying Party.

(b) In any Third-Party Claim for which indemnification is being sought under this ARTICLE X, the Indemnified Party or the Indemnifying Party, whichever is not assuming the defense of such Third-Party Claim, shall have the right to participate in such matter and to retain its own counsel at such party’s own expense. The Indemnifying Party or the Indemnified Party (as the case may be) shall at all times use reasonable efforts to keep the Stockholders’ Representative or Indemnified Party (as the case may be) reasonably apprised of the status of the defense of any matter, the defense of which it is maintaining, and to cooperate in good faith with the other party with respect to the defense of any such matter.

(c) No Indemnified Party may settle or compromise any Third-Party Claim or consent to the entry of any judgment with respect to which indemnification is being sought under this ARTICLE X without the prior written consent of the Stockholders’ Representative (which may not be unreasonably withheld, conditioned or delayed), unless (i) the Indemnifying Party fails to assume and maintain diligently the defense of such Third-Party Claim pursuant to Section 10.2(a) or fails to reimburse the Indemnified Party within 30 days for expenses incurred by the Indemnified Party in defending itself against any Third-Party Claim in the circumstance where the Indemnifying Party fails to assume the defense of the Indemnified Party or as required under the last sentence of Section 10.2(a) or, having assumed the defense, thereafter defaults in pursuing such defense, or (ii) such settlement, compromise or

64

consent includes an unconditional release of the Indemnifying Party and its officers, directors, employees and Affiliates from all liability arising out of, or related to, such Third-Party Claim without further actual or potential monetary liability to the Indemnifying Party. An Indemnifying Party may not, without the prior written consent of the Indemnified Party, settle or compromise any Third-Party Claim or consent to the entry of any judgment with respect to which indemnification is being sought under this ARTICLE X unless such settlement, compromise or consent (A) includes an unconditional release of the Indemnified Party and its officers, directors, employees and Affiliates from all liability arising out of, or related to, such Third-Party Claim, (B) does not contain any admission or statement suggesting any wrongdoing or liability on behalf of the Indemnified Party, and (C) does not contain any equitable order, judgment or term that in any manner affects, restrains or interferes with the business of the Indemnified Party or any of the Indemnified Party’s Affiliates.

(d) In the event an Indemnified Party claims a right to payment pursuant to this Agreement with respect to any Loss or other matter not involving a Third-Party Claim (a “ Direct Claim ”), such Indemnified Party shall send written notice of such claim to the Stockholders’ Representative (a “ Notice of Claim ”). Such Notice of Claim shall specify the basis for such Direct Claim. The failure by any Indemnified Party to so notify the Stockholders’ Representative shall not relieve the Indemnifying Party from any liability that it may have to such Indemnified Party with respect to any Direct Claim made pursuant to this Section 10.2(d), it being understood that Notices of Claim in respect of a breach of a representation or warranty must be delivered prior to the expiration of the survival period for such representation or warranty under Section 10.3. In the event the Stockholders’ Representative does not notify the Indemnified Party within ten (10) days following its receipt of such Notice of Claim that the Stockholders’ Representative disputes the Indemnifying Parties’ liability to the Indemnified Party under this ARTICLE X or the amount thereof, the Direct Claim specified by the Indemnified Party in such Notice of Claim shall be conclusively deemed a liability of the Indemnifying Party under this ARTICLE X, and the Indemnifying Party shall pay the amount of such liability to the Indemnified Party on demand or, in the case of any notice in which the amount of the Direct Claim (or any portion of the Direct Claim) is estimated, on such later date when the amount of such Direct Claim (or such portion of such Direct Claim) becomes finally determined, in each case with such payment to be rendered pursuant to the offset mechanism in accordance with Section 10.5. In the event the Stockholders’ Representative has timely disputed its liability with respect to such Direct Claim as provided in this Section 10.2(d), as promptly as reasonably practicable, such Indemnified Party and the Stockholders’ Representative shall establish the merits and amount of such Direct Claim (by mutual agreement, litigation or otherwise) and, within five (5) Business Days following the final determination of the merits and amount of such Direct Claim, the Indemnifying Party shall pay to the Indemnified Party in accordance with the offset mechanism pursuant to Section 10.5 an amount equal to such Direct Claim as determined pursuant to this Section 10.2(d). If a dispute exists as to the amount of any Direct Claim, the prevailing party shall be entitled to all legal and other fees paid in asserting or defending such Direct Claim, as the case may be (which legal and other fees, if owed by the Stockholders, shall be payable pursuant to the offset mechanism pursuant to Section 10.5).

Section 10.3 Survival Period . The representations, warranties and covenants made by the Company and the Stockholders in this Agreement and the Consideration Certificate shall not be extinguished by the Closing, but shall survive the Closing for, and all claims for indemnification in connection therewith shall be asserted not later than, 12 months following the Closing Date; provided, however , that (a) each of the representations and warranties contained in Section 2.1 (Organization and Good Standing), Section 2.2 (Capitalization), Section 2.3 (Subsidiaries), Section 2.4 (Authority; No Conflict; Required Filings and Consents), Section 2.16 (Employee Matters), Section 2.17 (Employee Benefit Plans), Section 2.20 (Brokerage and Transaction Bonuses), Section 2.21 (Title to and Sufficiency

Notwithstanding the foregoing, if, prior to the close of business on the last day a claim for indemnification may be asserted under this ARTICLE X, the Stockholders’ Representative shall have been properly notified of a claim for indemnity under this ARTICLE X and such claim shall not have been finally resolved or disposed of as of such date, such claim shall continue to survive and shall remain a basis for indemnity under this ARTICLE X until such claim is finally resolved or disposed of in accordance with the terms of this Agreement. All representations, warranties and covenants made by the Purchaser shall continue in accordance with their respective terms. Subject at all times to the limitations set forth in this ARTICLE X, the covenants and agreements of the parties pursuant to this ARTICLE X shall survive without limitation as to time, and the period during which a claim for indemnification may be asserted in connection therewith shall continue indefinitely, subject to applicable statutes of limitations.

Section 10.4 Investigations. The respective representations and warranties of the parties contained in this Agreement or any certificate or other document delivered by any party at or prior to the Closing and the rights to indemnification set forth in this ARTICLE X shall not be deemed waived or otherwise affected by any investigation made, or Knowledge acquired, by a party.

Section 10.5 Offset Against Escrow Shares, FDA Acceptance Consideration Shares, FDA Approval Consideration Shares and FDA Approval Cash Consideration . Notwithstanding anything in this Agreement to the contrary, in the event any Indemnified Party shall suffer any Losses for which such Indemnified Party is entitled to indemnification under this ARTICLE X, such Indemnified Party’s sole remedy shall be to recover such Losses by offsetting such Losses (subject to the limitations set forth in Section 10.6 and elsewhere in this ARTICLE X) against the Escrow Shares (with such shares valued at the Closing Per Share Price) until the Escrow Shares are wholly exhausted and, thereafter, the FDA Acceptance Consideration Shares, the FDA Approval Consideration Shares or the FDA Approval Cash Consideration.

Section 10.6 Limitations on Liability .

(a) The Indemnifying Parties will not be liable to the Indemnified Parties for indemnification under this ARTICLE X unless and until the aggregate Losses for which they would otherwise be liable under this ARTICLE X exceed $250,000, at which point the Indemnifying Parties shall be liable for the aggregate Losses in excess of $125,000.

66

(b) In no event shall the aggregate amount of the indemnification obligation of the Indemnifying Parties pursuant to this ARTICLE X exceed (i) 15% of the Closing Consideration, plus (ii) 15% of the FDA Acceptance Consideration Shares, but solely to the extent actually issued or determined to be issuable, plus (iii) 15% of each of the FDA Approval Consideration Shares and FDA Approval Cash Consideration, but in each case solely to the extent actually issued, paid, determined to be issuable or determined to be payable.

(c) Notwithstanding the foregoing to the contrary, each Stockholder’s aggregate liability with respect to a claim for indemnification under this ARTICLE X shall not exceed (i) 15% of the Closing Consideration actually issued or determined to be issuable to such Stockholder, plus (ii) 15% of the FDA Acceptance Consideration Shares actually issued or determined to be issuable to such Stockholder, plus (iii) 15% of each of the FDA Approval Consideration Shares and FDA Approval Cash Consideration, but in each case solely to the extent actually issued, paid, determined to be issuable or determined to be payable to such Stockholder; provided that no Stockholder shall be liable for the breach by any other Stockholder of the representations or warranties made by any other Stockholder pursuant to ARTICLE III or pursuant to any Stockholder Related Agreement.
