Any purchase of the Seller Shares by Purchaser shall be referred to herein as an “Acquisition.” The period from the date of the Option Agreement through the expiration of the Call Option Period shall be referred to herein as the “Option Period.”

AGREEMENT

The parties, intending to be legally bound, agree as follows:

CALL AND PUT OPTIONS

1.1 Purchaser’s Call Option.

(a) Purchaser’s Rights. Purchaser shall have an exclusive option to acquire, at its sole election and on the terms and conditions set forth herein, all, but not less than all, of the Seller Shares, which option may be exercised at any time during the Call Option Period. In connection therewith, each Seller hereby grants to Purchaser an exclusive right, exercisable at any time during the Call Option Period, to acquire all, but not less than all, of the Seller Shares held by such Seller on the terms set forth in this Section 1.1 (the “Call Option”).

(b) Exercise of Call Option.

(i) Notice. Purchaser may exercise the Call Option by giving notice, in substantially the form attached hereto as Exhibit B (the “Purchase Election Notice”), to the Sellers’ Representative (which, in turn, shall deliver copies of the Purchase Election Notice to each Seller), at any time during the Call Option Period. The Purchase Election Notice shall set forth the Purchaser’s calculation of the Initial Purchase Price (as defined below) and the proposed closing date of the Acquisition (which shall be the Business Day immediately following the expiration of the Call Option Review Period (as defined below)), in each case, subject to the dispute resolution procedures set forth in Section 1.11.

(ii) Disclosure Schedules.

(A) Attached to this Agreement is a schedule of disclosures and exceptions to the representations and warranties made by the Seller Parties pursuant to Section 2 and Section 3 of this Agreement (the “Seller Parties Disclosure Schedule”). At any time and from time to time during the Call Option Period, but no more than three (3) times during the Call Option Period, Purchaser may, upon written notice to the Sellers’ Representative (a “Disclosure Schedule Request”), require the Seller Parties to prepare, as if such representations and

warranties were made as of the date of such request, an updated schedule of disclosures and exceptions to the representations and warranties of the Seller Parties contained in Section 2 and Section 3 of the this Agreement (an “Updated Seller Parties Disclosure Schedule”), except to the extent any such representations and warranties refer expressly to an earlier date. The Acquired Company shall prepare and deliver to Purchaser an Updated Seller Parties Disclosure Schedule within ten (10) days of receipt of a Disclosure Schedule Request by the Sellers’ Representative. Any Updated Seller Parties Disclosure Schedule delivered pursuant to this Agreement shall refer only to (1) disclosures of actual facts contained in the Seller Parties Disclosure Schedule, and (2) disclosures of actual facts in existence on the date of such Updated Seller Parties Disclosure Schedule that have occurred or have been discovered since the Effective Date, and the Updated Seller Parties Disclosure Schedule shall not otherwise limit or modify any of the representations and warranties made in this Agreement. No disclosure of a fact or event on any Updated Seller Parties Disclosure Schedule shall be deemed to cure any failure to disclose such fact or event on any previously delivered Seller Parties Disclosure Schedule or Updated Seller Parties Disclosure Schedule, or otherwise amend any previously delivered Seller Parties Disclosure Schedule or Updated Seller Parties Disclosure Schedule.

(B) Within ten (10) days after receipt of the Purchase Election Notice, the Sellers’ Representative shall deliver to Purchaser an Updated Seller Parties Disclosure Schedule.

No disclosure of a fact or event on any Updated Seller Parties Disclosure Schedule shall be deemed to cure any failure to disclose such fact or event on any previously delivered Seller Parties Disclosure Schedule or Updated Seller Parties Disclosure Schedule, or otherwise amend any previously delivered Seller Parties Disclosure Schedule or Updated Seller Parties Disclosure Schedule. In the event an Updated Seller Parties Disclosure Schedule is not delivered to Purchaser within the ten (10) day time period, the most recent Updated Seller Parties Disclosure Schedule delivered to the Purchaser, or, if none, the Seller Parties Disclosure Schedule, shall be deemed to be the final Updated Seller Parties Disclosure Schedule for all purposes of this Agreement, and all references in this Agreement to the Updated Seller Parties Disclosure Schedule shall be deemed to refer to such most recent Updated Seller Parties Disclosure Schedule or Seller Parties Disclosure Schedule, as applicable.

(iii) Review Period. Purchaser shall have a further period of ten (10) days after receipt of such Updated Seller Parties Disclosure Schedule to review such Updated Seller Parties Disclosure Schedule (or if no such Updated Seller Parties Disclosure Schedule is delivered within the time period specified in paragraph above, then ten (10) days following the expiration of such period) (the “Call Option Review Period”), and shall have the right at its election to rescind its exercise of the Call Option, in its sole discretion, at any time during the Call Option Review Period by notice to the Sellers’ Representative (the “Call Option Rescission Notice”), if it is not satisfied in any manner with its review of such Updated Seller Parties Disclosure Schedule. In the event that Purchaser delivers a Call Option Rescission Notice to the

Sellers’ Representative within the Call Option Review Period, Purchaser shall be deemed to have not exercised the Call Option at such time, and the parties’ respective rights and obligations under this Agreement shall continue as though no Purchase Election Notice had been delivered until the expiration of the Call Option Period. In the event that Purchaser does not deliver a Call Option Rescission Notice during the Call Option Review Period, the closing of the Acquisition shall be consummated on the later of (x) the Business Day immediately following expiration of the Call Option Review Period in accordance with the terms herein and (y) the Business Day immediately following the final determination of the Initial Purchase Price pursuant to Section 1.11.

1.2 Sellers’ Put Option.

(a) Purchaser’s Obligations. In the event that the Acquired Company achieves the Base Milestones (as defined below) during the Put Option Period, Purchaser shall have an obligation, subject to Section 1.2(b)(iii) below, to acquire all of the Seller Shares on the terms and conditions set forth herein (the “Put Option”). In connection therewith, subject to Section 1.2(b)(iii), Purchaser shall have a binding obligation to acquire from each Seller all, but not less than all, of the Seller Shares held by such Seller on the terms set forth in this Section 1.2.

(b) Exercise of Put Option.

No disclosure of a fact or event on any Updated Seller Parties Disclosure Schedule shall be deemed to cure any failure to disclose such fact or event on any previously delivered Seller Parties Disclosure Schedule or Updated Seller Parties Disclosure Schedule, or otherwise amend any previously delivered Seller Parties Disclosure Schedule or Updated Seller Parties Disclosure Schedule.

In the event an Updated Seller Parties Disclosure Schedule is not delivered to Purchaser with the Second Put Option Notice, the most recent Updated Seller Parties Disclosure Schedule delivered to Purchaser, or, if none, the Seller Parties Disclosure Schedule, shall be deemed to be the final Updated Seller Parties Disclosure Schedule for all purposes of this Agreement, and all references in this Agreement to the Updated Seller Parties Disclosure Schedule shall be deemed to refer to such most recent Updated Seller Parties Disclosure Schedule or Seller Parties Disclosure Schedule, as applicable.

(iii) Review Period. Purchaser shall have a period of ten (10) days after receipt of such Updated Seller Parties Disclosure Schedule to review such Updated Seller Parties Disclosure Schedule (or if no such Updated Seller Parties Disclosure Schedule is delivered within the time period specified in paragraph above, then ten (10) days following the expiration of such period) (a “Second Put Option Review Period”), and shall not be obligated to consummate the Acquisition by notice to the Sellers’ Representative (a “Second Put Option Rescission Notice”), if (A) any Seller Parties have materially breached any of the representations, warranties or covenants set forth in this Agreement or the Preferred Stock Purchase Agreement or Purchaser’s rights under the Amended Articles or the Seller Parties are unable to deliver the certificate required under Section 7.1(e) hereof, (B) the Acquired Company has suffered or incurred a Material Adverse Effect, (C) the Acquired Company is subject to (1) an Action or there is an Action Threatened involving a claim that any Product infringes the proprietary rights of a third party, (2) an Action or there is an Action Threatened involving a claim that any Product has resulted in personal injury or death to a human patient or Purchaser in good faith has determined that a Product recall is required to correct a material defect in any Product, or (3) an Action or there is an Action Threatened or an investigation proceeding by any Governmental Body regarding the conduct of the Acquired Company or involving any Product, or (D) any of the Sellers breach their non-competition obligations under the Founders’ Non-Competition Agreements (as defined in the Preferred Stock Purchase Agreement) or the Investor Non-Competition Agreement (as defined in the Preferred Stock Purchase Agreement).

Any Updated Seller Parties Disclosure Schedule delivered pursuant to this Section shall refer only to (A) disclosures of actual facts contained in the Seller Parties Disclosure Schedule, and (B) disclosures of actual facts in existence on the date of such Updated Seller Parties Disclosure Schedule that have occurred or have been discovered since the date of this Agreement, and the Updated Seller Parties Disclosure Schedule shall not otherwise limit or modify any of the representations and warranties made in this Agreement.

In the event an Updated Seller Parties Disclosure Schedule is not delivered to Purchaser with the Second Cure Notice, the most recent Updated Seller Parties Disclosure Schedule delivered to Purchaser, or, if none, the Seller Parties Disclosure Schedule, shall be deemed to be the final Updated Seller Parties Disclosure Schedule for all purposes of this Agreement, and all references in this Agreement to the Updated Seller Parties Disclosure Schedule shall be deemed to refer to such most recent Updated Seller Parties Disclosure Schedule or Seller Parties Disclosure Schedule, as applicable.

1.11 Time for Determination; Dispute Mechanism.

(a) Initial Purchase Price. If Purchaser, at any time, objects to the Sellers determination that a Milestone has been completed, then Purchaser shall deliver a dispute notice (a “Pre-Closing Milestone Dispute Notice”) to the Sellers’ Representative within fifteen (15) days following delivery of the Milestone Completion Notice. Purchaser, on the one hand, and the Sellers’ Representative, on the other, shall attempt in good faith to resolve any such objections within fifteen (15) days of the receipt by the Sellers’ Representative of the Pre-Closing Milestone Dispute Notice. If no Pre-Closing Milestone Dispute Notice is delivered within the fifteen (15) day time period, then the Initial Purchase Price specified in the Milestone Completion Notice shall be deemed to be accepted.

(b) Milestone Payments. In the event that any Sellers believe that any Additional Milestone has been achieved during the Post-Closing Milestone Period, the Sellers’ Representative shall provide notice of such achievement to Purchaser. If Purchaser determines in its sole and reasonable discretion that such Additional Milestone has been achieved during the Post-Closing Milestone Period, then within thirty (30) days of such notice from Sellers’ Representative or, if earlier, within thirty (30) days of Purchaser’s determination that such Additional Milestone has been achieved, Purchaser shall notify Sellers’ Representative of its determination and pay to Sellers the Additional Milestone Payment payable in respect of such Additional Milestone. If Sellers’ Representative delivers such a notice and Purchaser determines, in its sole and reasonable discretion, that the applicable Additional Milestone has not been achieved, then, within thirty (30) days of Sellers’ Representative’s notice Purchaser shall notify Sellers’ Representative of such determination. If Sellers’ Representative believes that Sellers are entitled to payment of all or any portion of an Additional Milestone Payment hereunder which they have not received within thirty (30) days following the achievement of the Additional Milestone for which payment is due, Sellers’ Representative may, not later than twelve (12) months following the achievement of such Additional Milestone, deliver to Purchaser a notice setting forth Sellers’ Representative’s determination that all or a portion of such Additional Milestone Payment is due under this Agreement (the “Post-Closing Assessment Notice”). If Sellers’ Representative does not deliver to Purchaser a Post-Closing Assessment


***		Portions of this page have been omitted pursuant to a request for Confidential Treatment filed separately with the Commission.

Notice within such twelve (12) month period, then Sellers shall have been deemed to agree that the Additional Milestone has not been met and no payment with respect to such Additional Milestone is due to Sellers hereunder and Sellers shall have no further rights to such Milestone Payment or any portion thereof. Such Post-Closing Assessment Notice may be delivered before or after the expiration of the Post-Closing Milestone Period without affecting Sellers’ rights to the applicable Milestone Payment, provided that that applicable Additional Milestone was actually achieved prior to the expiration of such Post-Closing Milestone Period. If Purchaser shall object to Sellers’ determination that a Additional Milestone has been achieved as set forth in the Post-Closing Assessment Notice, then Purchaser shall deliver a dispute notice (a “Post-Closing Milestone Dispute Notice”) to Sellers’ Representative within fifteen (15) days following Sellers’ Representative’s delivery of the Post-Closing Assessment Notice. A representative of Purchaser, on the one hand, and the Sellers’ Representative, on the other, shall attempt in good faith to resolve any such objections within fifteen (15) days of the receipt by Sellers of the Post-Closing Milestone Dispute Notice. If no Post-Closing Milestone Dispute Notice is delivered within the fifteen (15) day time period, then Sellers’ determination that the Additional Milestone has been achieved, and that the amount of the Milestone Payment specified in the Post-Closing Milestone Dispute Notice is due hereunder, shall be deemed to be accepted and Purchaser shall pay to Sellers those amounts set forth in the Post-Closing Assessment Notice no later than five (5) days after the expiration of such fifteen (15) day time period.

(c) Second Put Option Condition. If Sellers at any time believe that the Second Put Option Condition has been satisfied and Sellers’ Representative has not received a Second Put Option Notice, the Sellers’ Representative shall deliver a notice of such achievement to Purchaser no later than thirty (30) days after the expiration of the Second Put Option Period (the “Second Put Option Dispute Notice,” and together with any Pre-Closing Milestone Dispute Notice and any Post-Closing Milestone Dispute Notice, a “Dispute Notice”). Purchaser, on the one hand, and the Sellers’ Representative, on the other, shall attempt in good faith to resolve within fifteen (15) days of the receipt by Purchaser of the Second Put Option Dispute Notice whether the Second Put Option Condition has been satisfied. If Sellers’ Representative fails to deliver the Second Put Option Dispute Notice within thirty (30) days following the expiration of the Second Put Option Period, it shall be definitively determined that the Second Put Option Condition has not been satisfied.

(d) Dispute Resolution. If Purchaser and Sellers shall be unable to resolve any such dispute within the fifteen (15) day period following the non-objecting party’s receipt of a Dispute Notice, then within five (5) days thereafter, Purchaser and the Sellers’ Representative shall designate an arbitrator to resolve any and all matters that remain in dispute and were properly included in the Dispute Notice. The dispute shall be resolved by arbitration in New York, New York administered by the American Arbitration Association in accordance with its Commercial Arbitration Rules (the “AAA Rules”), provided, however, that Purchaser and the Sellers’ Representative shall agree on the selection of an independent medical or scientific expert (the “Independent Expert”) who will make a report to the arbitrator which the arbitrator will be required to use as the basis for his or her decision. In the event that Purchaser and the Sellers’ Representative are unable to agree on the arbitrator within such five (5) day period, AAA will have the authority to select an arbitrator within five (5) Business Days thereafter. In the event that Purchaser and the Sellers’ Representative are unable to agree on the Independent Expert, the arbitrator shall have the authority to determine the Independent Expert. The Sellers’

Representative and Purchaser shall use reasonable efforts to cause the arbitrator to render a written decision resolving the matters submitted on a timely basis to the arbitrator within thirty (30) days of the receipt of such submission. The arbitrator’s decision shall be based solely on written submissions made on a timely basis by the Sellers’ Representative and Purchaser and their respective representatives and not by independent review. The arbitrator shall address only those items in dispute and may not assign 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. Judgment may be entered upon the determination of the arbitrator in any court having jurisdiction over the party against which such determination is to be enforced. The fees and expenses of the arbitrator incurred pursuant to this Section 1.11(d) shall be borne by Purchaser and Sellers (in accordance with their respective Proceeds Allocations), pro rata, based on the difference between the amount of the Initial Purchase Price or Milestone Payment (as the case may be), as finally determined by the arbitrator pursuant to this clause (d), and the amount of the Initial Purchase Price or Milestone Payment (as the case may be) asserted by each party in the Milestone Completion Notice, the Post-Closing Assessment Notice or the Second Put Option Notice, as the case may be, and the Dispute Notice, as applicable.

1.12 Acknowledgement of Sellers and Purchaser. Sellers and Purchaser acknowledge that (i) Purchaser has no obligation to aid or assist the Acquired Company in order to achieve any Milestone or to maximize any Milestone, (ii) the parties solely intend the express provisions of the Closing Documents to govern their contractual relationship, and (iii) unless and until Purchaser, at its sole election, issues a Purchase Election Notice, or unless and until the Sellers’ Representative issues a Milestone Completion Notice or Second Put Option Notice, Purchaser is under no obligation to purchase the Seller Shares from Sellers. The Sellers hereby waive, on their behalf and on behalf of any of their successors and assigns, any fiduciary duty (but, for avoidance of doubt, not any implied covenant of good faith and fair dealing) of Purchaser to Sellers, with respect to the matters contemplated by this Section 1.12.

1.13 Withholding. Purchaser shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to Sellers such amounts as Purchaser is required to deduct and withhold under any Tax law, with respect to the making of such payment. Purchaser shall notify Sellers of the basis for such withholding no less than fifteen (15) days prior to the proposed withholding and shall consider in good faith any views of Sellers with respect to whether such withholding is required under the United States Internal Revenue Code of 1986 (as amended), or any provisions of state or local Tax law, with respect to the making of such payment, provided however, that Sellers provide to Purchaser such documentation as Purchaser reasonably requests to support Sellers’ views with respect to whether such withholding is required.

1.14 Working Capital. One (1) day prior to the Closing, the Sellers’ Representative shall deliver to Purchaser a financial statement setting forth the Working Capital of the Business on the Closing Date.

This Agreement constitutes the legal, valid, and binding obligation of Purchaser, enforceable against Purchaser in accordance with its terms, subject to bankruptcy and other similar Legal Requirements of general applicability relating to or affecting creditors’ rights and to general equity principles. Upon the execution and delivery by Purchaser of the Closing Documents, the Closing Documents will constitute the legal, valid, and binding obligations of Purchaser, enforceable against Purchaser in accordance with their respective terms, enforceable against Purchaser in accordance with their respective terms, subject to bankruptcy and other similar Legal Requirements of general applicability relating to or affecting creditors’ rights and to general equity principles.

4.4 Brokers. Purchaser and its officers and agents have incurred no obligation or liability, contingent or otherwise, for brokerage or finders’ fees or agents’ commissions or other similar payment in connection with this Agreement and will indemnify and hold Sellers harmless from any such payment alleged to be due by or through Purchaser as a result of the action of Purchaser or its officers or agents.

(d) Indemnification by the Sellers. Each Seller agrees, as a consequence of the inclusion of any of such Seller’s shares of Purchaser Common Stock in the Mandatory Registration Statement, severally and not jointly, to (i) indemnify and hold harmless Purchaser, its directors, its officers who sign the Mandatory Registration Statement and each person, if any, who controls Purchaser within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which Purchaser or

such other persons may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Mandatory Registration Statement, or any amendment or supplement, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to Purchaser by or on behalf of such Seller, and (ii) reimburse Purchaser and such other persons for any legal or other expenses reasonably incurred by Purchaser in connection with investigating or defending any such action or claim as such expenses are incurred.

5.10 Right of First Refusal/Right of Notice.

(a) Right of First Refusal. After the expiration of the Option Period through the termination of the Distribution Agreement, if the Acquired Company receives a bona fide offer from any party with respect to any transaction which would result in the sale of substantially all of the Acquired Company’s assets or the sale of all or such portion of the Acquired Company’s capital stock such that, following such transaction, the buyer would own shares having a majority of the combined voting power on a fully diluted basis of all of classes of the Acquired Company’s equity securities (each, a “Sale of the Acquired Company”), the Acquired Company shall provide Purchaser a copy of the offer (upon condition of confidentiality) (the “Sale Notice”). On receipt of the Sale Notice, Purchaser shall have the right and option (the “Right of First Refusal”), exercisable at any time by providing written notice to the Acquired Company during the period of fifteen (15) Business Days following Purchaser’s receipt of the Sale Notice, to elect to purchase all, but not less than all, of the offered securities or assets in connection with the Sale of the Acquired Company, at the same price and upon the same terms and conditions contained in the Sale Notice (the “Purchaser Notice”). The Acquired Company will not, following receipt of the Purchaser Notice through the date ninety (90) days thereafter (the “ROFR Period”), for so long as Purchaser continues to negotiate with the Acquired Company the terms of a definitive agreement, directly or indirectly, facilitate, solicit, recommend or encourage any offer by, or enter into any agreement with any person or entity that would, if the transaction contemplated thereby were completed, result in a Sale of the Acquired Company.

(b) Failure to Agree. If Purchaser does not deliver a Purchase Election Notice within fifteen (15) Business Days of the Sale Notice or if after good faith negotiations Purchaser and the Acquired Company are unable to agree upon the terms of a definitive agreement for a Sale of the Acquired Company during the ROFR Period, then the Acquired Company shall be free for a period of one (1) year to enter into a Sale of the Acquired Company with the buyer identified in the Sale Notice on substantially the terms set forth in the Sale Notice which financial terms and conditions shall not be less favorable to the Acquired Company when taken in their totality than the terms and conditions last offered in writing by Purchaser to the Acquired Company during the ROFR Period.

(c) Right of Notice. After the expiration of the Option Period through the termination of the Distribution Agreement, (i) if the Acquired Company decides to commence

discussion with any party with respect to a Sale of the Acquired Company, then the Acquired Company will provide Purchaser with notice of such within three (3) Business Days of the commencement of such discussions or (ii) if the Acquired Company receives a proposal or offer from any party with respect to any transaction that would result in a Sale of the Acquired Company, and the Acquired Company decides to proceed with such proposal or offer, the Acquired Company shall provide Purchaser with notice and a brief description of any offer or proposal within three (3) Business Days of the receipt of such offer or proposal.

5.11 Sellers’ Right to Audit Purchaser’s Net Sales.

(a) Within thirty (30) days following the expiration of the Put Option Period, Purchaser shall deliver a sales report to the Sellers with respect to Purchaser’s Net Sales of the Products during each of the first two (2) years during the Put Option Period. The sales report shall include Net Sales of Products by month during each of the two years during the Put Option Period.

(b) Within thirty (30) days following the end of each calendar quarter ending during the Call Option Period, Purchaser shall deliver a sales report to the Sellers with respect to Purchaser’s Net Sales of Products during the most recently completed calendar quarter ending during the Call Option Period. The sales report shall include Net Sales of Products by month during the most recent completed calendar quarter.

(c) At any time during the Call Option Period and during the thirty (30) day period following the expiration of the Call Option Period, up to a maximum of two (2) times, the Purchaser shall permit, upon reasonable written notice from the Sellers’ Representative to Purchaser and at Sellers’ sole expense, an independent auditor with a nationally recognized certified public accounting firm selected by the Sellers’ Representative and reasonably acceptable to Purchaser to audit the books and records of Purchaser to verify Net Sales of Products. If such inspections should disclose underreporting of Net Sales by an amount of five percent (5%) or greater, Purchaser shall reimburse Sellers for the cost of the audit within five (5) Business Days of the completion date of the Sellers’ audit. In the event Purchaser has underreported Net Sales, Sellers shall be entitled to use the post-audit calculations for purposes of determining whether Sellers are entitled to receive a Milestone Payment or exercise their Put Option or Second Put Option under this Agreement, in each case, subject to the dispute resolution procedures set forth in Section 1.11. Any audit shall not unreasonably interfere with Purchaser’s business activities.

The remedies provided in this Section 6.2 will not be exclusive of or limit any other remedies that may be available to the Purchaser Indemnified Persons under this Section 6.

(c) Notwithstanding anything else herein to the contrary, for purposes of determining whether there has been a Breach of the representations and warranties of the Seller Parties under Sections 2 and 3 hereof, each representation and warranty which refers to the “Effective Date” shall be true and correct as of the “Closing Date” notwithstanding that such representation or warranty, as the case may be, refers to the “Effective Date,” provided that such representations and warranties shall be qualified by each Updated Seller Parties Disclosure Schedule to the extent there are any disclosures of actual facts in existence on the date of such Updated Seller Parties Disclosure Schedule that have occurred or been discovered since the Effective Date, and (i) such disclosures are not material, or (ii) the Acquired Company obtained the approval of the Supervisory Board of Directors of the Acquired Company (including the director designated by the Purchaser) or the prior written consent of the Purchaser Representative (as defined in the Preferred Stock Purchase Agreement) pursuant to Section 5.1 of the Preferred Stock Purchase Agreement with respect to an action of the Acquired Company which action directly caused such material change.

(b) Notwithstanding anything to the contrary set forth in this Agreement, the total Damages payable by Sellers pursuant to Section 6.2 shall not exceed an amount equal to *** percent (***%) of the Aggregate Purchase Price (the “Cap”), except to the extent (i) such Damages are due to fraud or intentional misrepresentation of any of the Sellers, or (ii) such Damages are due to a breach of a Fundamental Representation; provided, however, that in no event shall the aggregate amount of Damages recoverable from any Seller pursuant to Section 6.2 exceed *** ; and provided further, any *** shall be excluded from counting towards the Cap.

(c) Notwithstanding anything to the contrary set forth in this Agreement, the total Damages payable by Purchaser pursuant to Section 6.3 shall not exceed the Cap, except to the extent (i) such Damages are due to fraud or intentional misrepresentation of any of the Purchaser, or (ii) such Damages are due to a breach of a Fundamental Representation; and provided, that any *** shall be excluded from counting towards the Cap.

(d) With respect to any Damages recoverable by the Purchaser Indemnified Persons for the matters referred to in Section 6.2, the Purchaser Indemnified Persons shall be obligated to first exhaust the General Escrow Amount or any right of set-off pursuant to Section 6.9 hereof or Section 7.3 of the Preferred Stock Purchase Agreement before proceeding against any Seller.

(e) Neither the Sellers nor Purchaser shall have any liability under any provision of this Agreement for any multiple of damages or diminution in value, other than for diminution in value of the Product(s).

6.5 No Bar. Subject to Section 6.4(d), if the General Escrow Amount is insufficient to set off the aggregate of all claims made hereunder for Damages, then Purchaser may take any action or exercise any remedy available to it by appropriate legal proceedings to collect any such Damages.

6.6 Procedure for Indemnification—Third Party Claims.

(a) Promptly after receipt by an Indemnified Person under Section 6.2 or Section 6.3 of notice of the commencement of any Proceeding against it, such Indemnified Person will, if a claim is to be made against an Indemnifying Person under such Section, give notice to the Indemnifying Person of the commencement of such claim, but the failure to notify the Indemnifying Person will not relieve the Indemnifying Person of any liability that it may


***		Portions of this page have been omitted pursuant to a request for Confidential Treatment filed separately with the Commission.

have to any Indemnified Person, except to the extent that the Indemnifying Person demonstrates that the defense of such action is prejudiced by the Indemnified Person’s failure to give such notice.

(b) If any Proceeding referred to in Section 6.6(a) is brought against an Indemnified Person and it gives notice to the party from which such Indemnified Person is entitled to receive indemnification (an “Indemnifying Person”) of the commencement of such Proceeding, the Indemnifying Person will be entitled to participate in such Proceeding and, to the extent that it wishes (unless (i) the Indemnifying Person is also a party to such Proceeding and the Indemnified Person determines in good faith that joint representation would be inappropriate, or (ii) the Indemnifying Person fails to provide reasonable assurance to the Indemnified Person of its financial capacity to defend such Proceeding and provide indemnification with respect to such Proceeding), to assume the defense of such Proceeding with counsel satisfactory to the Indemnified Person and, after notice from the Indemnifying Person to the Indemnified Person of its election to assume the defense of such Proceeding, the Indemnifying Person will not, as long as it diligently conducts such defense, be liable to the Indemnified Person under this Section 6 for any fees of other counsel or any other expenses with respect to the defense of such Proceeding, in each case subsequently incurred by the Indemnified Person in connection with the defense of such Proceeding, other than reasonable costs of investigation. If the Indemnifying Person assumes the defense of a Proceeding, (i) it will be conclusively established for purposes of this Agreement that the claims made in that Proceeding are within the scope of and subject to indemnification; (ii) no compromise or settlement of such claims may be effected by the Indemnifying Person without the Indemnified Person’s consent unless (A) there is no finding or admission of any violation of Legal Requirements or any violation of the rights of any Person, provided such settlement or compromise would not materially and adversely prejudice the business or other commercial interests of the Indemnified Person, and (B) the sole relief provided is monetary damages that are paid in full by the Indemnifying Person; and (iii) the Indemnified Person will have no liability with respect to any compromise or settlement of such claims effected without its consent. If notice is given to an Indemnifying Person of the commencement of any Proceeding and the Indemnifying Person does not, within ten (10) days after the Indemnified Person’s notice is given, give notice to the Indemnified Person of its election to assume the defense of such Proceeding, the Indemnifying Person will be bound by any determination made in such Proceeding or any compromise or settlement effected by the Indemnified Person if it is ultimately determined that the Indemnified Person is entitled to indemnification.

(c) Notwithstanding the foregoing, if an Indemnified Person determines in good faith that there is a reasonable probability that a Proceeding may adversely affect it or its Affiliates other than as a result of monetary damages for which it would be entitled to indemnification under this Agreement, the Indemnified Person may, by notice to the Indemnifying Person, assume the exclusive right to defend, compromise, or settle such Proceeding, but the Indemnifying Person will not be bound by any determination of a Proceeding so defended or any compromise or settlement effected without its consent (which may not be unreasonably withheld).

(d) Each Seller hereby consents to the non-exclusive jurisdiction of any court in which a Proceeding is brought against any indemnified party for purposes of any claim that an

Indemnified Person may have under this Agreement with respect to such Proceeding or the matters alleged therein, and agrees that process may be served on Sellers with respect to such a claim anywhere in the world.

6.7 Procedure for Indemnification—Other Claims. A claim for indemnification for any matter not involving a third-party claim may be asserted by notice to the party from whom indemnification is sought.

6.8 Remedies Exclusive. From and after the Closing, except in the event of fraud or willful misconduct (in which case the defrauded party shall have all rights and remedies available under this Agreement and available under the law against the party that committed such fraud or willful misconduct), the remedies provided in this Section 6 shall be the exclusive remedies of the parties hereto and their heirs, Affiliates, successors, and assigns after the Closing with respect to the representations and warranties set forth in this Agreement. Except as set forth in this Section 6.8, no party may bring or commence any Proceeding with respect to the representations and warranties set forth in this Agreement, whether in contract, tort or otherwise, except to bring a claim for (a) fraud or willful misconduct against the party that committed such fraud or willful misconduct and (b) indemnification in accordance with Section 6. Notwithstanding the foregoing, nothing contained in this Agreement shall limit the rights of any party hereto to seek or obtain injunctive relief or other equitable remedies to which such party may otherwise be entitled. The provisions of this Section 6 constitute an integral part of the consideration given pursuant to this Agreement and were specifically bargained for and reflected in the total amount of the Aggregate Purchase Price payable to the Sellers.

6.9 Rights of Set-Off. To the extent than any Purchaser Indemnified Person is (or may be) entitled to be indemnified by any Seller for Damages hereunder, Purchaser shall have the right to withhold and set-off against any amount otherwise due to be paid (but not yet paid) to such Seller pursuant to this Agreement the amount of any such Damages to which any Purchaser Indemnified Persons may be entitled under this Section 6 hereof or any other agreement entered into pursuant to this Agreement (except with respect to the Distribution Agreement); provided, that to the extent the amount so set-off exceeds the amount of Damages for which it is finally determined that such Purchaser Indemnified Person is entitled to be indemnified, promptly following such final determination, Purchaser shall remit such excess to the Sellers’ Representative.

6.10 Sellers’ Representative.

(a) By virtue of the approval and adoption of this Agreement by the requisite consent of the Sellers, each of the Sellers shall be deemed to have agreed to appoint each of ▇▇▇▇▇▇ ▇▇▇ ▇▇▇▇▇ and Joost D de Bruijn as its agent and attorney-in-fact and as the Sellers’ Representative for and on behalf of the Sellers to give and receive notices and communications, to authorize payment to any Indemnified Person from the Escrow Account in satisfaction of claims by any Indemnified Person, to object to such payments, to agree to, negotiate, enter into settlements and compromises of, and demand arbitration and comply with orders of courts and awards of arbitrators with respect to such claims, to assert, negotiate, enter into settlements and compromises of, and demand arbitration and comply with orders of courts and awards of arbitrators with respect to, any other claim by any Indemnified Person against any Seller or by

any Seller against any Indemnified Person or any dispute between any Indemnified Person and any such Seller, in each case relating to this Agreement or the transactions contemplated hereby, and to take all other actions that are either (i) necessary or appropriate in the judgment of the Sellers’ Representative for the accomplishment of the foregoing or (ii) specifically mandated by the terms of this Agreement or the Escrow Agreement. Such agency may be changed by the Sellers with the right to a majority of the Escrow Account from time-to-time. Notwithstanding the foregoing, the Sellers’ Representative may resign at any time by providing written notice of intent to resign to the Sellers, which resignation shall be effective upon the earlier of (A) thirty (30) calendar days following delivery of such written notice or (B) the appointment of a successor by the holders of a majority in interest of the Escrow Account. No bond shall be required of the Sellers’ Representative, and the Sellers’ Representative shall not receive any compensation for its services. Until notified in writing signed by an authorized person on behalf of the Sellers that the Sellers’ Representative has resigned or been removed and that a successor has been appointed, Purchaser shall be entitled to rely upon any instruction, notice, decision, action or inaction of the Sellers’ Representative whether in receipt of a writing signed by one or both of the individuals serving in such capacity. Any notice delivered by Purchaser or Sellers’ Representative, as the case may be, shall be delivered in accordance with Section 9.2 hereof.

(b) The Sellers’ Representative shall not be liable for any act done or omitted hereunder as Sellers’ Representative while acting in good faith, even if such act or omission constitutes negligence on the part of such Sellers’ Representative. The Sellers’ Representative shall only have the duties expressly stated in this Agreement and shall have no other duty, express or implied. The Sellers’ Representative may engage attorneys, accountants and other professionals and experts. The Sellers’ Representative may in good faith rely conclusively upon information, reports, statements and opinions prepared or presented by such professionals, and any action taken by the Sellers’ Representative based on such reliance shall be deemed conclusively to have been taken in good faith. The Sellers shall indemnify the Sellers’ Representative and hold the Sellers’ Representative harmless against any loss, liability or expense incurred on the part of the Sellers’ Representative (so long as the Sellers’ Representative was acting in good faith in connection therewith) and arising out of or in connection with the acceptance or administration of the Sellers’ Representative duties hereunder, including the reasonable fees and expenses of any legal counsel retained by the Sellers’ Representative and reasonable travel expenses for services rendered as Sellers’ Representative (“Sellers’ Representative Expenses”). The Sellers’ Representative shall have the right to retain Sellers’ Representative Expenses from the Escrow Account prior to any distribution to the Sellers. Prior to any such distribution from the Escrow Account, the Sellers’ Representative shall deliver to the Escrow Agent a certificate setting forth the Sellers’ Representative Expenses actually incurred. A decision, act, consent or instruction of the Sellers’ Representative, including an amendment, extension or waiver of this Agreement pursuant to its authority hereunder, shall constitute a decision of the Sellers and shall be final, binding and conclusive upon the Sellers.

WHEREAS, the Purchaser is entering into an Option Purchase Agreement with the Acquired Company and the Sellers, dated as of January 8, 2009 (the “Option Purchase Agreement”), pursuant to which Purchaser may purchase from the Sellers all of the outstanding capital stock of the Acquired Company (the “Acquisition”).

WHEREAS, pursuant to the terms of the Option Purchase Agreement, at the sole election of the Purchaser, all or a portion of the Initial Purchase Price or Milestone Payments (collectively, the “Aggregate Purchase Price”) may be paid by Purchaser to the Sellers in the form of shares of common stock (“Purchaser Common Stock”) of the Purchaser (the “Stock Consideration”), with the exact number of shares determined based on the closing price (the “Closing Price”) of the Purchaser Common Stock on the Qualified Stock Exchange on the Trading Day (as defined below) immediately prior to the date of each applicable payment (each, a “Payment Date”). For purposes of this Agreement, the term “Trading Day” shall mean any day when the Qualified Stock Exchange is open for trading.

WHEREAS, pursuant to Section 1.6(b)(iii) of the Option Purchase Agreement, Purchaser has elected to cause each of the Sellers to execute this Agreement.

NOW, THEREFORE, in consideration of the mutual covenants contained herein, the parties hereto agree as follows:

Section 1. Appointment of Market Maker. In the event that the Purchaser elects to issue Stock Consideration as any portion of the Aggregate Purchase Price:

(a) Each Seller agrees to engage ____________(the “Market Maker”) to serve as its sole broker for the sale of any Purchaser Common Stock issued by Purchaser as part of the Stock Consideration during the thirty (30) Trading Days immediately following a Payment Date (each such period, a “Trading Period”); and

(b) Each Seller agrees to execute an irrevocable Letter of Instruction to the Market Maker in the form attached hereto as Exhibit A.

Section 2. Adjustments to Stock Consideration.

(a) If a Seller sells all or a portion of the Purchaser Common Stock issued at a Payment Date in a sale executed by the Market Maker prior to the expiration of the Trading Period associated with such Payment Date (the “Expiration Date”) at a price per

- 1 -

share below the Closing Price, as adjusted for stock splits, stock dividends, reclassifications or similar events (any such sale price hereinafter referred to as the “Sale Price”), the Purchaser shall pay to the Seller in cash an amount equal to (i) the product of the Closing Price and the number of shares of Purchaser Common Stock sold by such Seller at such Sale Price during the relevant Trading Period, less (ii) the product of such Sale Price and the number of shares of Purchaser Common Stock sold by such Seller at such Sale Price during the relevant Trading Period (each of (i) and (ii) above as adjusted for stock splits, stock dividends, reclassifications or similar events). The increase in Stock Consideration payable to any Seller shall hereinafter be referred to as the “True-Up Amount.” As soon as practicable following determination of the True-Up Amount and receipt of evidence of the True-Up Amount reasonably satisfactory to Purchaser through the delivery of stock confirmation or account records, and subject to Section 2(c) herein, Purchaser shall pay the True-Up Amount to the Seller in cash.

(b) If a Seller sells all or a portion of the Purchaser Common Stock issued at a Payment Date in a sale executed by the Market Maker prior to the Expiration Date associated with such Payment Date at a Sale Price above the Closing Price, as adjusted for stock splits, stock dividends, reclassifications or similar events, the Seller shall pay to Purchaser in cash (i) the product of the applicable Sale Price and the number of shares of Purchaser Common Stock sold by such Seller at such Sale Price during the relevant Trading Period, less (ii) the product of the Closing Price and the number of shares of Purchaser Common Stock sold by such Seller at such Sale Price during the relevant Trading Period (each of (i) and (ii) above as adjusted for stock splits, stock dividends, reclassifications or similar events). The decrease in Stock Consideration payable to any Seller shall hereinafter be referred to as the “Excess Amount.” Seller will cause the Market Maker to retain the Excess Amount, for and on behalf of the Purchaser, out of the Seller’s proceeds from the sale of Purchaser Common Stock.

1. Escrow Fund.

(a) Pursuant to Section 1.9 of the Option Purchase Agreement, as soon as reasonably practicable after the Closing Date, Purchaser shall cause the Escrow Cash to be deposited with the Escrow Agent. Escrow Agent agrees to accept delivery of the Escrow Cash and to hold such Escrow Cash in escrow subject to the terms and conditions of this Agreement and the Option Purchase Agreement.

2. Escrow Period. The period during which claims for Damages may be made (the “Claims Period”) shall commence at the Closing and terminate on (a) in case of the General Escrow Fund, the date that is eighteen (18) months after the Closing (the “General Escrow Period”) and (b) in the case of the Special Escrow Fund, the date that after the Closing (or earlier pursuant to Part 3.20(c) of the Seller Parties Disclosure Schedule (as defined in the Option Agreement) in which case at such time Purchaser shall direct the Escrow Agent to release such portion of the remaining Special Escrow Fund to the Sellers in accordance with the Proceeds Allocation set forth on Schedule I) (the “Special Escrow Period”). Notwithstanding the foregoing, all or a portion of the General Escrow Fund may be retained beyond the General Escrow Period as provided in Section 5(a) of this Agreement.

3. Rights and Obligations of the Parties.

(a) The Escrow Agent shall be entitled to such rights and shall perform such duties as escrow agent as set forth herein and as set forth in the Option Purchase Agreement (collectively, the "Duties”), in accordance with the provisions of this Agreement and the Option Purchase Agreement. Such Duties shall include the following: (i) safeguarding and treating the Escrow Fund as a trust fund in accordance with the provisions of this Agreement and not as the property of Purchaser, and holding the Escrow Fund in a separate account, apart from any other funds or accounts of the Escrow Agent or any other Person and (ii) holding and disposing of the Escrow Fund only in accordance with the provisions of this Agreement. The Duties of the Escrow Agent with respect to the Escrow Cash may be altered, amended, modified or revoked only by a writing signed by Purchaser, the Escrow Agent and the Sellers’ Representative.

(b) Purchaser and the Sellers’ Representative shall be entitled to their respective rights and shall perform their respective duties and obligations as set forth herein and in the Option Purchase Agreement, in accordance with the provisions of this Agreement and the Option Purchase Agreement.

4. Claims Against the Escrow Fund.

(a) On or before the last day of the General Escrow Period or the Special Escrow Period, as the case may be, Purchaser may deliver to the Escrow Agent a certificate signed by any officer of Purchaser (an “Officer’s Certificate”):

(i) stating that a Purchaser Indemnified Person has incurred, paid, reserved or accrued, or reasonably anticipates that it may incur, pay, reserve or accrue, Damages (or that with respect to any Tax matters, that any Governmental Body may raise such matter in an audit of Purchaser or its subsidiaries, which are reasonably likely to give rise to Damages);

(ii) stating the amount of such Damages (which, in the case of Damages not yet incurred, paid, reserved or accrued, may be the maximum amount reasonably anticipated by Purchaser to be incurred, paid, reserved or accrued);

(iii) specifying in reasonable detail (based upon the information then possessed by Purchaser) the individual items of such Damages included in the amount so stated and the nature of the claim to which such Damages are related; and

(iv) stating whether the claim is against the General Escrow Fund or the Special Escrow Fund.

No delay in providing such Officer’s Certificate within the General Escrow Period or Special Escrow Period, as the case may be, shall affect any Purchaser Indemnified Person’s rights hereunder, unless (and then only to the extent that) any Seller is materially prejudiced thereby.

(b) At the time of delivery of any Officer’s Certificate to the Escrow Agent, a duplicate copy of such Officer’s Certificate shall be delivered to the Sellers’ Representative by or on behalf of Purchaser (on behalf of itself or any other Purchaser Indemnified Person) and, in the case of a claim against the General Escrow Fund, for a period of 30 days after such delivery to the Escrow Agent of such Officer’s Certificate, the Escrow Agent shall make no payment pursuant to this Section 4 unless the Escrow Agent shall have received written authorization from the Sellers’ Representative to make such delivery. After the expiration of such 30-day period, the Escrow Agent shall make delivery of cash in the amount of the maximum Damages set forth in such Officer’s Certificate from the General Escrow Fund to Purchaser in accordance with this Section 4; provided, however, that no such delivery may be made if and to the extent the Sellers’ Representative shall object in a written statement to any claim or claims made in the Officer’s Certificate, and such statement shall have been delivered to the Escrow Agent and to Purchaser prior to the expiration of such 30-day period. In the case of a claim against the Special Escrow Fund, upon delivery of any Officer’s Certificate to the Escrow Agent, the Escrow Agent shall immediately release the Special Escrow Cash to Purchaser, and in no event shall the Sellers’ Representative object to the release of such funds by the Escrow Agent.

(c) If the Sellers’ Representative objects in writing to any claim or claims by Purchaser against the General Escrow Fund made in any Officer’s Certificate within such 30-day period, Purchaser and the Sellers’ Representative shall attempt in good faith for 30 days after Purchaser’s receipt of such written objection to resolve such objection. If Purchaser and the Sellers’ Representative shall so agree, a memorandum setting forth such agreement shall be prepared and signed by both parties and delivered to the Escrow Agent. The Escrow Agent shall be entitled to conclusively rely on any such memorandum and the Escrow Agent shall distribute cash from the General Escrow Fund in accordance with the terms of such memorandum. If no such agreement can be reached during the 30-day period for good faith negotiation, then upon the expiration of such 30-day period, either Purchaser or the Sellers’ Representative may bring proceeding pursuant to the dispute resolution proceedings set forth in Section 9.4 of the Option Purchase Agreement to resolve the matter. The decision of the arbiter as to the validity and amount of any claim in such Officer’s Certificate shall be nonappealable, binding and conclusive upon the parties to this Agreement and the Escrow Agent shall be entitled to act in accordance with such decision and shall distribute cash from the General Escrow Fund in accordance therewith.

5. Distribution of Escrow Fund Upon Expiration of the Escrow Periods.

(a) Retention of Funds to Satisfy Pending Claims. Such portion of the General Escrow Fund at the conclusion of the General Escrow Period that may be necessary to satisfy any unresolved or unsatisfied claims made against the General Escrow Fund for Damages specified in any

Officer’s Certificate delivered to the Sellers’ Representative and Escrow Agent prior to expiration of the General Escrow Period (the “Reserve Amount”) shall remain in the General Escrow Fund until such claims for Damages have been resolved or satisfied pursuant to Section 6 of the Option Purchase Agreement and prior to such resolution or satisfaction of any such claim, none of the Reserve Amount shall be delivered or distributed to any Person; provided, that prior to any distribution to Sellers pursuant to this Section 5(b), the Escrow Agent shall first distribute to the Sellers’ Representative on behalf of the Sellers an amount in respect of the Sellers’ Representative Expenses actually incurred as set forth in a certificate delivered by the Sellers’ Representative to the Escrow Agent prior to such distribution. For purposes of determining at any particular time the amount of Escrow Cash in the General Escrow Fund that is necessary or sufficient to satisfy and/or provide for all such claims, Purchaser shall be assumed to be entitled to the full amount of Damages stated in good faith in such Officer’s Certificate(s). The amount retained in the General Escrow Fund after the expiration of the General Escrow Period with respect to a particular pending claim shall be available to Purchaser only with respect to such pending claim and shall not be available to Purchaser for any other pending claim. The General Escrow Amount shall be available to Purchaser only with respect to claims made under Section 6.2 of the Option Purchase Agreement and the Special Escrow Amount shall be available to Purchaser only with respect to claims made under Section 6.11 of the Option Purchase Agreement.

(b) Distributions from Escrow Fund to the Sellers. Promptly after the expiration of the General Escrow Period or the Special Escrow Period, as the case may be, and in any event no later than thirty (30) days after such expiration, such portion of the then remaining General Escrow Fund in excess of any Reserve Amount and such portion of the then remaining Special Escrow Fund shall be paid to the Sellers in accordance with the Proceeds Allocation set forth on Schedule I hereto (the “Proceeds Allocation”); provided, however, that prior to any distribution to Sellers pursuant to this Section 5(b), the Escrow Agent shall first distribute to the Sellers’ Representative on behalf of the Sellers an amount in respect of the Sellers’ Representative Expenses actually incurred as set forth in a certificate delivered by the Sellers’ Representative to the Escrow Agent prior to such distribution. The Escrow Agent need not monitor or inquire into the Sellers’ tax treatment of funds distributed to them and shall allocate for income tax purposes the income earned on the Escrow Fund to Purchaser in accordance with Section 6(b).

(c) Distributions of Reserve Amount. Promptly following the resolution or satisfaction of any claim for Damages relating to any portion of the Reserve Amount (and in any event no later than thirty (30) after such resolution and satisfaction), such portion of the Reserve Amount shall be paid to Purchaser and/or to the Sellers, as the case may be, in accordance with the terms of a memorandum setting forth an agreement between Purchaser and the Sellers’ Representative or the artbiter’s decision, as applicable. No Reserve Amount shall be subject to any claim or right of offset except with respect to the claim for which such Reserve Amount was retained following the expiration of the General Escrow Period.

6. Investment of Escrow Cash.

(a) The Escrow Agent shall hold the Escrow Cash in escrow and shall invest the Escrow Cash and any interest or income thereon only in Permitted Investments. “Permitted Investments” shall mean (i) such investments as may be specified from time to time by written instruction from the Purchaser or (ii) in the absence of written instructions to the contrary, investments in the Escrow Agent’s insured money market account as described in Annex A hereto (“IMMA”). Notwithstanding the foregoing, Permitted Investments shall be limited to the following (1) direct obligations of the United States government having maturities of 90 days or less, (2) money market funds that invest solely in direct obligations of the United States government, (3) repurchase obligations for underlying securities of the types described in clause (1) and (4) the IMMA. The Escrow Agent or any of its affiliates may receive compensation with respect to any investment directed hereunder. The Escrow Agent will act

upon investment instructions the day that such instructions are received, provided the requests are communicated within a sufficient amount of time to allow the Escrow Agent to make the specified investment. Instructions received after an applicable investment cutoff deadline will be treated as being received by the Escrow Agent on the next business day, and the Escrow Agent shall not be liable for any loss arising directly or indirectly, in whole or in part, from the inability to invest funds on the day the instructions are received. The Escrow Agent shall not be liable for any loss incurred by the actions of third parties or for any loss arising by error, failure or delay in the making of an investment or reinvestment, and the Escrow Agent shall not be liable for any loss of principal or income in connection therewith, unless such error, failure or delay results from the Escrow Agent’s gross negligence, willful misconduct, fraud or breach of this Agreement. As and when the Escrow Cash and any interest or income thereon is to be released under this Agreement, the Escrow Agent shall cause the Permitted Investments to be converted into cash in accordance with its customary procedures and shall not be liable for any loss of principal or income in connection therewith. The Escrow Agent shall not be liable for any loss of principal or income due to the choice of Permitted Investments in which the Escrow Cash is invested or the choice of Permitted Investments converted into cash pursuant to this Section 6.

(b) All interest attributable to the Escrow Cash shall first be distributed to Purchaser up to any amount paid in fees to the Escrow Agent. Any remaining interest shall be added to the Escrow Cash and be part of the Escrow Fund for all purposes hereunder. At the time of delivery to the Sellers, the Escrow Agent shall deliver to the Sellers any accrued but unpaid interest on such amount of the Escrow Cash distributable to the Sellers hereunder (but not any accrued and unpaid interest on such amount of the Escrow Cash that is distributable to Purchaser hereunder, which shall instead be delivered to Purchaser, except to the extent the memorandum or arbiter’s decision relating to such amounts awarded to Purchaser specifically states that interest has already been taken to account and included in such awarded amount, in which case such interest shall be distributed to Sellers). The parties acknowledge that, for tax reporting purposes, all interest attributable to the Escrow Cash, and interest thereon, held in the Escrow Fund by the Escrow Agent pursuant to this Agreement shall be allocable to Purchaser.

7. Exculpatory Provisions.

(a) The Escrow Agent shall be obligated only for the performance of such Duties as are specifically set forth herein and may rely and shall be protected in relying or refraining from acting on any instrument reasonably believed to be genuine and to have been signed or presented by the proper party or parties. The Escrow Agent shall not be liable for forgeries or false impersonations. The Escrow Agent shall not be liable for any act done or omitted hereunder as escrow agent except for gross negligence, willful misconduct or breach of this Agreement. The Escrow Agent shall in no case or event be liable for any representations or warranties of the Sellers, the Sellers’ Representative or Purchaser or for punitive, incidental or consequential damages. Any act done or omitted pursuant to the advice or opinion of counsel shall be conclusive evidence of the good faith of the Escrow Agent.

(b) In the event of a dispute between the parties hereto, the Escrow Agent is hereby expressly authorized to disregard any and all notifications given by any of the parties hereto or by any other person, excepting only memoranda of agreement as provided in Section 9.4 of the Option Purchase Agreement and orders or process of courts of law as provided in Section 9.4 of the Option Purchase Agreement to which Escrow Agent shall be entitled to conclusively rely and shall distribute the Escrow Fund in accordance with the terms thereof, and is hereby expressly authorized to comply with and obey orders, judgments or decrees of any court. In case the Escrow Agent obeys or complies with any such order, judgment or decree of any court, the Escrow Agent shall not be liable to any of the parties hereto or to any other person by reason of such compliance, notwithstanding any such order, judgment, or decree being subsequently reversed, modified, annulled, set aside, vacated or found to have been entered without jurisdiction.

(c) In the event of any ambiguity or uncertainty hereunder or in any notice, instruction or other communication received by the Escrow Agent hereunder, the Escrow Agent may, in its sole discretion, refrain from taking any action other than retaining possession of the Escrow Fund, unless the Escrow Agent receives written instructions, signed by Purchaser and the Sellers’ Representative, which eliminates such ambiguity or uncertainty.

(d) The Escrow Agent shall not be liable in any respect on account of the identity, authority or rights of the parties executing or delivering or purporting to execute or deliver the Option Purchase Agreement, this Agreement or any documents or papers deposited or called for thereunder or hereunder.

(e) The Escrow Agent shall not be liable for the outlawing of any rights under any statute of limitations with respect to the Option Purchase Agreement, this Agreement or any documents deposited with the Escrow Agent.

8. Resignation and Removal of the Escrow Agent. The Escrow Agent may resign as escrow agent of the Escrow Fund at any time, with or without cause, by giving at least thirty (30) days’ prior written notice to each of Purchaser and the Sellers’ Representative, such resignation to be effective thirty (30) days following the date such notice is given. In addition, Purchaser and the Sellers’ Representative may jointly remove the Escrow Agent as escrow agent at any time, with or without cause, by an instrument executed by Purchaser and the Sellers’ Representative (which may be executed in counterparts) given to the Escrow Agent, which instrument shall designate the effective date of such removal. In the event of any such resignation or removal, a successor escrow agent, which shall be a bank or trust company organized under the laws of the United States of America or of the State of New York having (or if such bank or trust company is a member of a bank company, its bank holding company shall have) a combined capital and surplus of not less than $50,000,000, shall be appointed by Purchaser on the terms of this Agreement with the written approval of the Sellers’ Representative, which approval shall not be unreasonably withheld or delayed. In the event that a successor escrow agent has not been appointed within thirty (30) days after notice of the Escrow Agent’s resignation or removal the Escrow Agent shall be entitled to petition a court of competent jurisdiction to have a successor escrow agent appointed. Any such successor escrow agent shall deliver to Purchaser and the Sellers’ Representative, a written instrument accepting such appointment, and thereupon it shall succeed to all the rights and duties of the escrow agent hereunder and shall be entitled to receive possession of the Escrow Fund. Upon receipt of the identity of the successor escrow agent, the Escrow Agent shall deliver the Escrow Fund then held hereunder to the successor escrow agent.

9. Sellers’ Representative. The Sellers’ Representative (and each successor as such, as of the time he, she or it becomes the Sellers’ Representative) represents and warrants to the Escrow Agent that he, she or it has the right, power and authority to enter into an perform this Agreement as agent of and on behalf of the Sellers, to give and receive all directions and notices hereunder and to make all determinations that may be required or that he, she or it deems appropriate under this Agreement. Until notified in writing signed by an authorized person on behalf of the Sellers that the Sellers’ Representative has resigned or been removed and that a successor (named therein) has been appointed, the Escrow Agent shall be entitled to rely upon any instruction, notice, decision, action or inaction of the Sellers’ Representative whether in receipt of a writing signed by one or both of the individuals serving in such capacity, and shall have no duty to inquire into the authority of any person reasonably believed by the Escrow Agent to be the Sellers’ Representative.

10. Further Instruments. If the Escrow Agent reasonably requires other or further instruments in connection with its performance of the Duties, the necessary parties hereto shall join in furnishing such instruments.

11. Disputes. It is understood and agreed that should any dispute arise with respect to the delivery and/or ownership or right of possession of the cash and/or other property held by the Escrow Agent hereunder, the Escrow Agent is authorized and directed to act in accordance with, and in reliance upon, the provisions of this Agreement and the Option Purchase Agreement. Section 9.4 of the Option Purchase Agreement insofar as it relates to submission to jurisdiction and dispute resolution procedures in the event of any dispute solely between Purchaser and the Sellers’ Representative under any section of this Agreement is hereby incorporated by reference.

12. Escrow Fees and Expenses. Purchaser shall pay the Escrow Agent such fees and reimburse the Escrow Agent for such expenses as are established and contemplated by the Fee Schedule attached hereto as Annex B.

13. Indemnification. In consideration of the Escrow Agent’s acceptance of this appointment, Purchaser and the Sellers’ Representative (on behalf of the Sellers), hereby jointly and severally, agree to indemnify and hold the Escrow Agent harmless as to any liability incurred by it to any person, firm or corporation by reason of its having accepted such appointment or in carrying out the provisions of this Agreement and the Option Purchase Agreement, and to reimburse the Escrow Agent for all its costs and expenses (including, without limitation, counsel fees and expenses) reasonably incurred by reason of any matter as to which such indemnity is paid pursuant to this Section 13; provided, however, that no indemnity need be paid in case of the Escrow Agent’s gross negligence, willful misconduct, fraud or breach of this Agreement.

15. Tax Reporting Matters. Purchaser and the Sellers’ Representative each agree to provide the Escrow Agent with certified tax identification numbers for Purchaser and the Sellers, respectively, by furnishing appropriate Forms W-9 (or Forms W-8, in the case of non-U.S. persons) and other forms and documents that the Escrow Agent may reasonably request (collectively, “Tax Reporting Documentation”) to the Escrow Agent within 30 days after the Closing Date. The parties hereto understand that, if such Tax Reporting Documentation is not so certified to the Escrow Agent, the Escrow Agent may be required by the Internal Revenue Code of 1986 (the “Code”), as it may be amended from time to time, to withhold a portion of any payments made to Purchaser or the Sellers pursuant to this Agreement. If the date of a payment from the Escrow Fund occurs more than six months after the Closing Date, a portion of the payment will be treated by the Sellers as imputed interest to the extent required under the Code. The Escrow Agent need not monitor the Sellers’ tax treatment of any distributions made to them.

16. Patriot Act Compliance. To help the government fight the funding of terrorism and money laundering activities, federal law requires all financial institutions to obtain, verify and record information that identifies each person who opens an account. For a non-individual person such as a business entity, a charity, a trust or other legal entity the Escrow Agent will ask for documentation to verify its formation and existence as a legal entity. The Escrow Agent may also ask to see financial statements, licenses, identification and authorization documents from individuals claiming authority to represent the entity or other relevant documentation. Purchaser and the Sellers’ Representative each agree to provide all such information and documentation as to Purchaser and the Sellers as requested by Escrow Agent to ensure compliance with federal law.
