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 Indemnifying Party shall have the right, upon written notice from the Stockholders’ Representative delivered to the Indemnified Party within ten (10) Business 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 Date, (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) Business 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

51

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 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) Business 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 . 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).

10.3

Survival Period . The representations, warranties and covenants made by the Company and the Stockholders in this Agreement and the Purchased Share Certificate shall not be extinguished by

52

the Closing, but shall survive the Closing for, and all claims for indemnification in connection therewith shall be asserted not later than, twelve (12) months following the Closing Date; provided , however , that (a) each of the Fundamental Representations shall survive the Closing without limitation as to time, and the period during which a claim for indemnification may be asserted in connection therewith shall continue indefinitely; (b) each of the representations and warranties contained in Section 2.12 (Intellectual Property) and Section 2.15 (Environmental Matters), shall survive the Closing until, and all claims for indemnification in connection therewith shall be asserted not later than 60 days following, the expiration of any statute of limitations applicable to the rights of any Person to bring any claim with respect to such matters; and (c) each of the representations and warranties contained in Section 2.9 (Taxes) shall survive until, and all claims for indemnification in connection therewith shall be asserted not later than the later to occur of: (i) the 180th day following the end of the period, if any, during which an assessment, reassessment or other form of document assessing liability for Taxes in respect of any taxation year to which these representations and warranties extend could be issued to the Company, and (ii) 60 days following the expiration of any statute of limitations applicable to the rights of any Person to bring any claim with respect to such matters. 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.

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 any Person.

10.5

Offset Against Closing Shares and Future Product Payments . 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 shall be entitled to recover such Losses by offsetting such Losses against the Escrowed Closing Consideration up until it is released pursuant to Section 1.7(c) and the Escrow Agreement or until the Escrowed Closing Consideration is wholly exhausted and, thereafter, any remaining portion of such Losses shall be satisfied by the Indemnifying Party solely by offsetting such Losses against any Future Product Payments that have yet to be paid and are otherwise payable by the Purchaser or the Company to the Indemnifying Party. In no event shall the aggregate amount of the indemnification obligation of the Indemnifying Parties pursuant to this ARTICLE X exceed the sum of the Escrowed Closing Consideration and the Future Product Payments.

10.6

Set-Off . The Purchaser shall be entitled to set-off any amount or right it may be entitled to pursuant to this Agreement against any amount, right or obligations owed to any Stockholder under this Agreement or any Stockholder Related Agreement.

10.7

Characterization of Indemnification Payments . The Purchaser and the Stockholders agree to treat any payment made under this ARTICLE X as an adjustment to the Escrowed Closing Consideration.

53

ARTICLE XI. STOCKHOLDERS’ REPRESENTATIVE

11.1

Stockholders’ Representative .

(a)

Each of the Stockholders, by such Stockholder’s execution of this Agreement or a Joinder Agreement, hereby irrevocably appoints the Stockholders’ Representative as agent and attorney in fact for the Company and such Stockholder, and authorizes the Stockholders’ Representative (i) to take all action necessary to consummate the transactions contemplated by this Agreement and the Escrow Agreement, or the defense and/or settlement of any claims for which such Stockholder may be required to indemnify the Purchaser or any other Indemnified Party pursuant to ARTICLE X , (ii) to give and receive all notices required to be given under this Agreement, the Escrow Agreement or the Stockholder Related Agreements, (iii) to authorize delivery to the Purchaser of the Escrowed Closing Consideration or the Future Product Payments to the extent necessary for the Purchaser to exercise its rights under Section 1.7 or ARTICLE X , (iv) to make decisions on behalf of the Company and such Stockholder and take any and all additional action as is contemplated to be taken by or on behalf of such Stockholder by the terms of this Agreement or the Escrow Agreement, including, without limitation regarding (A) indemnification claims, Direct Claims, Third-Party Claims and Notices of Claims, (B) amendments to this Agreement, the Escrow Agreement or the Stockholder Related Agreements, and (C) the Future Product Payments.

(b)

All decisions and actions by the Stockholders’ Representative, including without limitation (i) any agreement between the Stockholders’ Representative and the Purchaser relating to the defense or settlement of any claims for which the Stockholders may be required to indemnify the Purchaser pursuant to ARTICLE X , and (ii) any agreement between the Stockholders’ Representative and the Purchaser relating to the Escrow Agreement or the determination of the Specified Indebtedness Amount under Section 1.7 or any other matter relating to ARTICLE I or the Future Product Payments, shall be binding upon all of the Stockholders, and no Stockholder shall have the right to object, dissent, protest or otherwise contest the same.

(c)

The Stockholders’ Representative shall not have any liability to any of the parties to this Agreement or to the Stockholders for any act done or omitted pursuant to this Agreement as the Stockholders’ Representative while acting in good faith, and any act done or omitted pursuant to the advice of counsel shall be conclusive evidence of such good faith. The Stockholders shall severally indemnify the Stockholders’ Representative and hold the Stockholders’ Representative harmless against any loss, liability or expense incurred without fraud or bad faith on the part of the Stockholders’ Representative and arising out of or in connection with the acceptance or administration of the Stockholders’ Representative’s duties under this Agreement.

(d)

The Stockholders’ Representative shall have full power and authority on behalf of each Stockholder to take any and all actions on behalf of, execute any and all instruments on behalf of, and execute or waive any and all rights of, the Stockholders under this Agreement, the Escrow Agreement and the Stockholder Related Agreements.

(e)

Each of the Stockholders, by such Stockholder’s execution of this Agreement or a Joinder Agreement, agrees, in addition to the foregoing, that:

(i)

the Purchaser shall be entitled to rely conclusively on the instructions and decisions of the Stockholders’ Representative as to (A) the settlement of any claims for indemnification by the Purchaser pursuant to ARTICLE X , (B) actions taken in respect of indemnification claims, Direct Claims, Third-Party Claims, Notices of Claims, the Specified Indebtedness Amount, and the Future Product Payments, and (C) any other actions required or permitted to be taken by the Stockholders’ Representative under this Agreement, the Escrow Agreement and any Stockholder

54

Related Agreement, and no Stockholder shall have any cause of action against the Purchaser for any action taken by the Purchaser in reliance upon the instructions or decisions of the Stockholders’ Representative;

(ii)

all actions, decisions and instructions of the Stockholders’ Representative shall be conclusive and binding upon the Company and all of the Stockholders and no Stockholder shall have any cause of action against the Stockholders’ Representative for any action taken, decision made or instruction given by the Stockholders’ Representative under this Agreement or the Escrow Agreement except for fraud or willful misconduct by the Stockholders’ Representative in connection with the matters described in this ARTICLE XI ; and

(iii)

the provisions of this ARTICLE XI are independent and severable, are irrevocable and coupled with an interest and shall be enforceable notwithstanding any rights or remedies that any Stockholder may have in connection with the transactions contemplated by this Agreement, the Escrow Agreement and the Stockholder Related Agreements.

(f)

The provisions of this ARTICLE XI shall be binding upon the executors, heirs, legal Representatives, personal Representatives, successor trustees and successors of each Stockholder, and any reference in this Agreement or the Escrow Agreement to a Stockholder or the Stockholders shall mean and include the successors to the rights of the Stockholders under this Agreement, whether pursuant to testamentary disposition, the laws of descent and distribution or otherwise.

Each of the parties hereto consents to the jurisdiction of such court (and of the appropriate appellate courts therefrom) in any such suit, action, or proceeding and irrevocably agrees not to commence any litigation relating thereto except in such court, and each further waives any objection to the laying of venue of any such litigation in such court and agrees not to plead or claim in such court that such litigation brought therein has been brought in an inconvenient forum.  Any party hereto may make service on another party by sending or delivering a copy of the process to the party to be served at the address and in the manner provided for the giving of notices in Section 12.10.

The Escrow Agent shall not be liable for any action taken, suffered or omitted to be taken by it in good faith except to the extent that the Escrow Agent’s gross negligence or willful misconduct are determined by a court of competent jurisdiction through a final order to have been the cause of any direct loss to either Party. The Escrow Agent may execute any of its powers and perform any of its duties hereunder directly or through its agents, representatives, attorneys, custodians and/or nominees. In the event the Escrow Agent shall be uncertain, or believes there is some ambiguity, as to its duties or rights hereunder, or receives instructions, claims or demands from any Party which, in the Escrow Agent’s judgment, conflict with the provisions of this Agreement, or if the Escrow Agent receives conflicting instructions from the Parties, the Escrow Agent shall be entitled either to (i) refrain from taking any action until it shall be given either (A) a joint written direction executed by Authorized Representatives of the Parties which eliminates such conflict, or (B) a court order issued by a court of competent jurisdiction (it being understood that the Escrow Agent shall be entitled conclusively to rely and act upon any such court order and shall have no obligation to determine whether any such court order is final) or by a final court order, or (ii) file an action in interpleader. Anything in this Agreement to the contrary notwithstanding, in no event shall the Escrow Agent be liable for special, incidental, punitive, indirect or consequential loss or damage of any kind whatsoever (including

but not limited to lost profits), even if the Escrow Agent has been advised of the likelihood of such loss or damage and regardless of the form of action.

(c) 

The Parties hereby acknowledge and agree that the value of the Escrow Shares as set forth in Section 4(h) has been negotiated and agreed between the Parties and that the Escrow Agent shall not be liable or responsible for any diminution in value, or fluctuation in value, with respect to the Escrow Shares due to any decrease or increase (or any subsequent decrease or increase) in the fair market value of the Purchaser Common Stock following the date of this Agreement.

10. 

Termination . The terms of this Agreement shall terminate upon the release by the Escrow Agent of the entire Escrow Fund in accordance with this Agreement; provided , however ,   that if on or prior to the Escrow Fund Release Date, the Escrow Agent has received from the Purchaser a Claim Notice in accordance with the terms and requirements set forth in Section 4 and elsewhere in this Agreement, setting forth a claim that has not been fully resolved by the Escrow Fund Release Date, then this Agreement shall continue in full force and effect with respect to that portion of the Escrow Fund necessary to resolve each such unresolved claim for the purpose of resolving such unresolved claim until such claim has been fully resolved and the retained amount released in accordance with this Agreement. Notwithstanding the foregoing, in no event shall this Agreement cease to remain in full force and effect until such time as all assets deposited hereunder have been distributed by the Escrow Agent per the terms of this Agreement.

11. 

Successor Escrow Agent . In the event the Escrow Agent becomes unavailable or unwilling to continue as escrow agent under this Agreement, the Escrow Agent may resign and be discharged from its duties and obligations hereunder by giving its written resignation to the Parties upon 30 days’ prior written notice to the Parties. In addition, the Escrow Agent may be removed at any time, with or without cause, upon 30 days’ prior written notice delivered to the Escrow Agent and executed by both the Purchaser and the Stockholders’ Representative. Such resignation or removal shall take effect not less than 30 days after notice is given to all Parties and the Escrow Agent. In such event, the Purchaser may appoint, with the consent of the Stockholders’ Representative, which consent shall not be unreasonably withheld, conditioned or delayed, a successor Escrow Agent, which shall be a commercial bank, trust company or other financial institution with a combined capital and surplus in excess of $100,000,000 (unless otherwise agreed by the Parties in writing), that will be an unrelated third party with respect to each of the Purchaser and the Stockholders’ Representative. If the Purchaser fails to appoint a successor Escrow Agent within 15 days after receiving the Escrow Agent’s written resignation, the Escrow Agent shall have the right to apply to a court of competent jurisdiction for the appointment of a successor Escrow Agent or appoint a successor Escrow Agent of its own choice. Any appointment of a successor Escrow Agent shall be binding upon the Purchaser, each of the Stockholders and the Stockholders’ Representative, and no appointed successor Escrow Agent shall be deemed to be an agent of the Escrow Agent. The successor Escrow Agent shall execute and deliver to the Escrow Agent an instrument accepting such appointment on the terms and conditions contained in this Agreement, and the successor Escrow Agent shall, without further acts, be vested with all the estates, property rights, powers and duties of the predecessor Escrow Agent as if originally named as the Escrow Agent herein. The Escrow Agent shall act in accordance with written instructions from the Purchaser and the Stockholders’ Representative as to the transfer of the Escrow Fund to a successor Escrow Agent, at which time the Escrow Agent’s obligations under this Agreement shall cease and terminate. Any entity into which the Escrow Agent may be merged or converted or with which it may be consolidated, or any entity to which all or substantially all the escrow business may be transferred, shall be the Escrow Agent under this Agreement without further act.

12. 

Stockholders’ Representative .

(a) 

Appointment .   As between the Parties, each Stockholder has approved the indemnification and escrow terms set forth in the Stock Purchase Agreement and the appointment of the Stockholders’ Representative to give and receive notices and communications, to authorize delivery to the Purchaser of Escrowed Closing Consideration or Additional Property or to object to such deliveries, to agree to, negotiate, enter into settlements and compromises of and demand arbitration, and comply with orders of courts and awards of arbitrator(s) with respect to claims of the Indemnified Parties hereunder, and to take all actions necessary or appropriate in the reasonable judgment of the Stockholders’ Representative for the accomplishment of the foregoing.

(b) 

Successor Stockholders’ Representative . If the Stockholders’ Representative or any successors thereto shall be dissolved or otherwise be unable to fulfill such Stockholders’ Representative’s responsibilities as the agent of the stockholders of the Company, then the Stockholders’ Representative shall, within 10 calendar days after

such event, appoint a successor representative reasonably satisfactory to the Purchaser, subject to such successor representative’s compliance with Patriot Act requirements and the consent of the Escrow Agent. Unless and until the Purchaser and the Escrow Agent shall have received written notice of the appointment of a successor Stockholders’ Representative, the Purchaser and the Escrow Agent shall be entitled to rely on, and shall be fully protected in relying on, the power and authority of the Stockholders’ Representative to act on behalf of the Stockholders.

13. 

Miscellaneous .

(a) 

Waiver and Amendment .   Any agreement on the part of a Party or the Escrow Agent to any extension or waiver of any provision hereof shall be valid only if set forth in an instrument in writing signed on behalf of such Party and the Escrow Agent. A waiver by a Party or the Escrow Agent of the performance of any covenant, agreement, obligation, condition, representation or warranty shall not be construed as a waiver of any other covenant, agreement, obligation, condition, representation or warranty. A waiver by any Party or the Escrow Agent of the performance of any act shall not constitute a waiver of the performance of any other act or an identical act required to be performed at a later time. This Agreement may not be amended, modified, altered or supplemented except by written agreement of the Parties and the Escrow Agent.

(b)

As directed by the Stockholders’ Representative in connection with any such delivery.

Security Procedure for Funds Transfer .  Concurrent with the execution of this Escrow Agreement, the Parties shall deliver to the Escrow Agent authorized signers’ forms in the form of Exhibit C-1 hereto and Exhibit C-2 hereto.  The Escrow Agent shall confirm each funds transfer instruction received in the name of Parties by confirming with an authorized individual as evidenced in Exhibit C-1 hereto and Exhibit C-2 hereto.  Once delivered to the Escrow Agent, Exhibit C-1 hereto or Exhibit C-2 hereto may be revised or rescinded only in writing signed by an authorized representative of the Party.  Such revisions or rescissions shall be effective only after actual receipt and following such period of time as may be necessary to afford the Escrow Agent a reasonable opportunity to act on it.  If a revised Exhibit C-1 hereto or Exhibit C-2 hereto or a rescission of an existing Exhibit C-1 hereto or Exhibit C-2 hereto is delivered to the Escrow Agent by an entity that is a successor-in-interest to either party, such document shall be accompanied by additional documentation satisfactory to the Escrow Agent showing that such entity has succeeded to the rights and responsibilities of the Parties.  The Parties understand that the Escrow Agent’s inability to receive or confirm funds transfer instructions may result in a delay in accomplishing such funds transfer, and agree that the Escrow Agent shall not be liable for any loss caused by any such delay.

The Parties represent, warrant and covenant that each document, notice, instruction or request provided by such Party to the Escrow Agent shall comply with applicable laws and regulations.

expressly and irrevocably consents and submits to the exclusive jurisdiction of the Court of Chancery of the State of Delaware or, if such court lacks jurisdiction, any state or federal court sitting in the State of Delaware (and each appellate court located in the State of Delaware), in connection with any legal proceeding;

(ii)

agrees not to assert (by way of motion, as a defense or otherwise), in any such legal proceeding commenced in any state or federal court located in the County of New Castle, State of Delaware, any claim by any party to this Agreement that it is not subject personally to the jurisdiction of such court, that such legal proceeding has been brought in an inconvenient forum, that the venue of such proceeding is improper or that this Agreement or the subject matter of this Agreement may not be enforced in or by such court.

(i) 

Waiver of Immunity . To the extent that in any jurisdiction any party to this Agreement may now or hereafter be entitled to claim, for itself or its assets, immunity from suit, execution, attachment (before or after judgment) or other legal process, such party to this Agreement shall not claim, and hereby irrevocably waives, such immunity.
