WHEREAS, the board of directors of the Company (the “Company Board”) has approved and adopted the form of this Agreement and the consummation of the transactions contemplated hereby, and has determined to submit the execution and delivery of this Agreement and the performance of the transactions contemplated hereby to the holders (the “Company Stockholders”) of the shares of the Company’s Common Stock, $0.001 par value per share (the “Company Common Stock”), and Preferred Stock, $0.001 par value per share (the “Company Preferred Stock”), for their approval in accordance with Delaware Law and the terms of the Company’s Amended and Restated Certificate of Incorporation; and

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements herein contained and intending to be legally bound hereby, Parent, Merger Sub, the Company and the members of the Stockholder Representative Committee hereby agree as follows:

form attached hereto as Exhibit A (the “Merger Certificate”), executed by appropriate officers of the Company. The Merger Certificate shall be retained by Parent and filed upon the Closing .

(b) The Merger. After execution and delivery of the Merger Certificate, upon the terms hereof and subject to the conditions set forth herein, and in accordance with Delaware Law, at the Effective Time, Merger Sub shall be merged with and into the Company and, as a result of the Merger, the separate corporate existence of Merger Sub shall cease, and the Company shall continue as the surviving corporation of the Merger (the surviving corporation is referred to herein as the “Surviving Corporation”).

Section 1.2 Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in the Merger Certificate and as provided by the applicable provisions of Delaware Law. Without limiting the generality of the foregoing, and subject thereto, upon the consummation of the Merger, all the property (including, but not limited to, Intellectual Property and licenses to Intellectual Property), rights, privileges, powers and franchises of the Company and the Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities, obligations, restrictions, disabilities and duties of each of those corporations shall become the debts, liabilities, obligations, restrictions, disabilities and duties of the Surviving Corporation.

During the period following delivery of the Capitalization and Closing Payment Amount Certificate and prior to the Closing, the Company shall provide Parent with reasonable access to the Company’s books of account and records used to prepare the Capitalization and Closing Payment Amount Certificate, and the management of the Company, for the purpose of verifying the amounts set forth therein.

(b) Net Cash Payment. At the Closing and deemed to be effective as of the time immediately prior to the Effective Time (after giving effect to all (i) exercises of Company Options, (ii) exercises of warrants to purchase Company Common Stock and Company Preferred Stock and (iii) conversions of Company Preferred Stock into Company Common Stock, that are elected by the holders thereof to be made prior to the Effective Time), the Company shall make a payment (the “Net Cash Payment”) allocated among the Company Stockholders in accordance

with the terms of the Company’s Certificate of Incorporation as in effect as of the earlier of the time of such Net Cash Payment or the time immediately prior to the Effective Time, and among the holders of outstanding unexercised Company Options (assuming the exercise of all of such Company Options for cash immediately prior to such Net Cash Payment, whether or not such exercise is actually elected by the holder thereof prior to the Effective Time), an amount in cash (the “Net Cash Amount”), if any, equal to the amount, if any, by which (i) the Cash On-Hand Amount set forth in the Capitalization and Closing Payment Amount Certificate, exceeds (ii) the sum of the Indebtedness Amount, the Transaction Costs, the Company Payables Amount and the Accrued Vacation Amount, each as set forth in the Capitalization and Closing Payment Amount Certificate.

The portion of the Closing Payment to be contributed hereunder on behalf of each Participating Rights Holder described above to the Committee Reimbursement Amount shall be proportionate to that portion of the Closing Payment that such Participating Rights Holder would otherwise be entitled to receive hereunder.

(ii) “Company Incremental Amount” means, with respect to any Contingent Payment Year, the amount equal to the Worldwide Net Sales for such Contingent Payment Year, minus the amount of Worldwide Net Sales for the immediately completed previous Contingent Payment Year; provided, that in the event that the final Contingent Payment Year is a period of less than twelve months, the Company Incremental Amount for such final Contingent Payment Year shall be an amount equal to the Worldwide Net Sales for such final Contingent Payment Year minus the aggregate Worldwide Net Sales for the same calendar months during the immediately prior Contingent Payment Year as are included in the final Contingent Payment Year; and provided, further, that if the amount otherwise determined in accordance with this definition for any Contingent Payment Year is not greater than zero, then the Company Incremental Amount for such Contingent Payment Year shall be deemed to be zero.

(iii) “Company Product” means the Company’s Complete TransCervical Sterilization System for use in permanent female sterilization as it has been developed by Company prior to the Closing, and as it may be improved or modified by the Parent or the other members of the Buyer Group after the Closing for use in permanent female sterilization.

For purposes of this definition, “valid and enforceable claim” means a claim of an issued and unexpired patent that has not been held revoked, unenforceable or invalid by a court or administrative or other government agency of competent jurisdiction and that has not been admitted to be invalid or unenforceable through reissue, reexamination, disclaimer or otherwise.

Notwithstanding anything to the contrary in this Agreement, in no event shall any Contingent Payment Year commence after December 31, 2012, and the Contingent Payment Year ending December 31, 2012 in accordance with the preceding sentence shall be deemed to be the final Contingent Payment Year for all purposes of this Agreement.

achieved on or prior to January 31, 2008) or $2,000,000 (if the FDA Milestone is achieved after January 31, 2008) multiplied by a fraction, the numerator of which is the day of the month on which the FDA Milestone is achieved, and the denominator of which is the total number of days in such month. Notwithstanding anything to the contrary in this Agreement, in the event that there has been a Pregnancies Event prior to the achievement of the FDA Milestone, the FDA Milestone Payment Amount shall be equal to zero.

(xi) “Maximum Sales Contingent Amount” means the amount of $130,000,000, provided, that in the event that the FDA Milestone Payment Amount for purposes of the FDA Milestone Payment is actually calculated to be zero as a result of the occurrence of a Pregnancies Event, then the Maximum Sales Consideration Contingent Amount shall be increased above $130,000,000 by an amount equal to the amount that the FDA Milestone Payment Amount would have been calculated to be in accordance with the definition thereof, had the Pregnancies Event not occurred.

(xii) “Per Unit Average Selling Price” means, with respect to a Contingent Payment Product, the amount equal to (x) the total amount of annual Worldwide Net Sales of such Contingent Payment Product, not including any such Contingent Payment Products that are sold as a Bundled Product, divided by (y) the total number of units of such Contingent Payment Products sold during such year, not including any such Contingent Payment Products that are sold as a Bundled Product. “Per Unit Average Selling Price” means, with respect to a product other than a Contingent Payment Product, the amount equal to (x) the total amount of annual worldwide revenue recognized by the Buyer Group for the sale of such other product, not including any such products that are sold as a Bundled Product, divided by (y) the total number of units of such products sold during such year, not including any such products that are sold as a Bundled Product.

(xiii) “Sales Contingent Payment Amount” means (a) with respect to the First Contingent Payment Year, an amount equal to 300% of the total Worldwide Net Sales of Contingent Payment Products recorded for the First Contingent Payment Year, (b) with respect to the Second Contingent Payment Year, an amount equal to 200% of the Company Incremental Amount for the Second Contingent Payment Year, (c) with respect to the Third Contingent Payment Year, an amount equal to 150% of the Company Incremental Amount for the Third Contingent Payment Year, and (d) with respect to the Fourth Contingent Payment Year, an amount equal to 150% of the Company Incremental Amount for the Fourth Contingent Payment Year. The Sales Contingent Payment Amount for the final Contingent Payment Year shall be subject to increase under certain circumstances in accordance with Section 6.11.

(xiv) “Second Recovery Contingent Payment Amount” means an amount equal to the difference of (x) $155,000,000, minus (y) the Maximum Sales Contingent Amount actually calculated in accordance with the definition thereof.

(xv) “Worldwide Net Sales” means revenue recorded by Parent (or any other applicable member of the Buyer Group if any sales contemplated hereby are recorded by such member of the Buyer Group but not by Parent) from the sales or license of Contingent Payment Products by a member of the Buyer Group or its sublicensee or authorized or licensed distributor after the Effective Time to unaffiliated third parties, in accordance with GAAP, consistently applied by Parent (or such other member of the Buyer Group) across all similar product lines, in connection with the preparation of the financial statements of such person, as publicly reported (if applicable). For purposes of clarification, when measuring the Worldwide Net Sales recorded in respect of sales of Contingent Payment Products by any person other than a member of the Buyer Group, only the revenue recorded by Parent or another member of the Buyer Group shall be included (for e.g., the transfer price or other amount received by Parent or such other member of the Buyer Group, in the event of any sales by an authorized or licensed distributor of the Contingent Payment Product manufactured by Parent, or the royalty or other license payment amounts received by Parent or another member of the Buyer Group in the case of any sales by another party which has been licensed to manufacture, market or sell Contingent Payment Products by Parent), and the amount of revenue that may be recorded or achieved by such other person who is not a member of the Buyer Group shall be disregarded. Notwithstanding anything to the contrary in this Agreement, any license payments or royalties payable in respect of the license or sublicense of Company Owned Intellectual Property or Company Licensed Intellectual Property after the Effective Time by any party that does not manufacture, market or sell Contingent Payment Products shall not be deemed to be “Worldwide Net Sales” for purposes of this Agreement.

(1) Notwithstanding anything to the contrary in this Agreement or in any financial statements prepared by Parent with respect to any Contingent Payment Year or portion thereof, or to the extent it may otherwise be required pursuant to GAAP, the term “Worldwide Net Sales” shall not include revenue recorded by Parent or any member of the Buyer Group from transactions with another member of the Buyer Group unless such other member of the Buyer Group is an end user of the Contingent Payment Product or no further resale by such member of the Buyer Group is contemplated; provided, however, that “Worldwide Net Sales” shall in such event include the revenue, if any, recorded upon the further resale of such Contingent Payment Product by such other member of the Buyer Group.

(2) Notwithstanding anything to the contrary in this Agreement or in any financial statements prepared by Parent with respect to any Contingent Payment Year or portion thereof, or to the extent it may otherwise be required pursuant to GAAP, whenever any Contingent Payment Product is sold as part of a Bundled Product and all products (including the applicable Contingent Payment Product) in such Bundled Product are sold on a “stand-alone” basis within the particular sales region of such sale, the “Worldwide Net Sales” for such Contingent Payment Product resulting from such sale of such Bundled Product shall be the product of (i) the revenue otherwise recorded by the applicable member of the Buyer Group for such Bundled Product multiplied by (ii) a fraction, the numerator of which is the Per Unit Average Selling Price of such Contingent Payment Product sold within such sales region and the denominator of which is the sum of (x) such numerator and (y) the aggregate Per Unit Average Selling Prices within such sales region of all other products included in such Bundled Product.

(b) Contingent Payments. In the event that the Merger is consummated, as additional consideration for the Merger, and subject to the set-off rights of Parent and the Surviving Corporation pursuant to Section 1.8(j) and Article 9 hereof, after the Effective Time, Parent shall make certain contingent payments (collectively, the “Contingent Payments”) to the Participating Rights Holders in accordance with the provisions of this Section 1.6 and Sections 1.8 and 2.1 hereof, and subject to the limitation on such contingent payments set forth in this Section 1.6 and Section 1.7 hereof and the provisions of Section 2.5. The Contingent Payments shall include the FDA Milestone Payment, the Sales Contingent Payments and the First Recovery Contingent Payment and Second Recovery Contingent Payment, as applicable.

(c) FDA Milestone Payment. Subject only to the set-off rights of Parent and the Surviving Corporation pursuant to Section 1.8(j) and Article 9 hereof, and other rights of reduction specifically contemplated hereby, Parent and the Surviving Corporation shall, jointly and severally, make a Contingent Payment (the “FDA Milestone Payment”) equal to the FDA Milestone Payment Amount following achievement of the FDA Milestone. Notwithstanding the foregoing, the consideration to be paid by Parent to the Participating Rights Holders at the time specified in Section 1.8 in connection with the FDA Milestone Payment shall be limited to that portion of the FDA Milestone Payment Amount allocated to such Participating Rights Holders pursuant to Section 2.1.

(d) Sales Contingent Payments. Subject only to the set-off rights of Parent and the Surviving Corporation pursuant to Section 1.8(j) and Article 9 hereof, and other rights of reduction specifically contemplated hereby, Parent and the Surviving Corporation shall, jointly and severally, make a Contingent Payment with respect to the sale of Contingent Payment Products recorded for each Contingent Payment Year (each, a “Sales Contingent Payment” and collectively, the “Sales Contingent Payments”), in accordance with Section 1.8. Notwithstanding the foregoing, the consideration to be paid by Parent to the Participating Rights Holders at the time specified in Section 1.8 in connection with each such Sales Contingent Payment shall be limited to that portion of the Sales Contingent Payment Amount for such Contingent Payment Year allocated to such Participating Rights Holders pursuant to Section 2.1.

(e) First Recovery Contingent Payment. In the event that (x) the FDA Milestone Payment Amount actually calculated in accordance with the definition thereof in connection with the making of the FDA Milestone Payment is less than $25,000,000 solely as a result of the FDA Milestone not being achieved before November 1, 2007, and (y) the Buyer Group reports aggregate Worldwide Net Sales equal to or greater than $110,000,000 during any Contingent Payment Year (provided, however, that if the final Contingent Payment Year contains fewer than twelve (12) months then, for the purposes of determining whether or not the Buyer Group reports aggregate Worldwide Net Sales equal to or greater than $110,000,000 during such final Contingent Payment Year for purposes of this paragraph (e) and the following paragraph (f) only, the final Contingent Payment Year shall be deemed to include that number of immediately preceding months in the preceding Contingent Payment Year that may be required so that the final Contingent Payment Year would consist of twelve (12) months), then, subject only to the set-off rights of Parent and the Surviving Corporation pursuant to Section 1.8(j) and Article 9 hereof, and other rights of reduction specifically contemplated hereby, Parent and the Surviving Corporation shall, jointly and severally, make a Contingent Payment (the “First Recovery Contingent Payment”) equal to the First Recovery Contingent Payment Amount.

Notwithstanding the foregoing, the consideration to be paid by the Parent and the Surviving Corporation to the Participating Rights Holders at the time specified in Section 1.8 in connection with the First Recovery Contingent Payment shall be limited to the portion of the First Recovery Contingent Payment Amount allocated to such Participating Rights Holders pursuant to Section 2.1.

(f) Second Recovery Contingent Payment. In the event that (x) the Pregnancies Event occurs, (y) the Buyer Group has reported aggregate Worldwide Net Sales equal to or greater than $110,000,000 in any Contingent Payment Year (provided, however, that if the final Contingent Payment Year contains fewer than twelve (12) months then, for the purposes of determining whether or not the Buyer Group reports aggregate Worldwide Net Sales equal to or greater than $110,000,000 during such final Contingent Payment Year for purposes of this paragraph (f) and the preceding paragraph (e) only, the final Contingent Payment Year shall be deemed to include that number of immediately preceding months in the preceding Contingent Payment Year that may be required so that the final Contingent Payment Year would consist of twelve (12) months), and (z) Parent has not paid Sales Contingent Payments based on Sales Contingent Payment Amounts equal in the aggregate to $155,000,000 then subject to the set-off rights of Parent and the Surviving Corporation pursuant to Section 1.8(j) and Article 9 hereof, and other rights of reduction specifically contemplated hereby, Parent and the Surviving Corporation shall, jointly and severally, make a one-time Contingent Payment (the “Second Recovery Contingent Payment”) equal to the Second Recovery Contingent Payment Amount. Notwithstanding the foregoing, the consideration to be paid by the Parent and the Surviving Corporation to the Participating Rights Holders at the time specified in Section 1.8 in connection with the Second Recovery Contingent Payment shall be limited to the portion of the Second Recovery Contingent Payment Amount allocated to each of such Participating Rights Holders pursuant to Section 2.1.

(g) Contingent Payments Not Certain. Each of Parent, the Company and the Stockholder Representative Committee hereby acknowledge that the achievement of the FDA Milestone is uncertain and that Parent and its Affiliates may not achieve the FDA Milestone, and it is therefore not assured that Parent will be required to pay the FDA Milestone Payment at all. Each of Parent, the Company and the Stockholder Representative Committee hereby further acknowledge that the amount of Worldwide Net Sales, if any, that Parent and its Affiliates may generate during any Contingent Payment Year is uncertain and that (i) Parent and its Affiliates may not generate any Worldwide Net Sales in any Contingent Payment Year, and (ii) it is therefore not assured that Parent will be required to make any Sales Contingent Payments for any particular Contingent Payment Year, or at all, or that either the First Recovery Contingent Payment or the Second Recovery Contingent Payment shall be payable.

(h) Parent Discretion. Without limiting the specific obligations of Parent in Sections 6.10 and 6.11, Parent shall have sole discretion over all matters relating to the Contingent Payment Products after the Effective Time, including, but not limited to, any development, testing, manufacturing, marketing and sales decisions relating to any Contingent Payment Product.

Section 1.7 Maximum Aggregate Sales Contingent Payments. Subject to the further rights of Parent and the Surviving Corporation to reduce the Contingent Payments

pursuant to Section 1.8 and Article 9 hereof, Parent shall not be required to make any Sales Contingent Payments once Parent has made Sales Contingent Payments equal to the Maximum Sales Contingent Amount. Upon distributing Sales Contingent Payments equal to the Maximum Sales Contingent Amount, Parent’s obligation to make any additional or future Sales Contingent Payments pursuant to Section 1.6 shall cease, and the rights of the Participating Rights Holders to receive any further Sales Contingent Payments shall terminate. To the extent that any provision of Section 1.6 would otherwise require Parent to make a Sales Contingent Payment resulting in Parent paying Sales Contingent Payments based on Sales Contingent Payment Amounts that, in the aggregate, exceed the Maximum Sales Contingent Amount, Parent shall be entitled to reduce such Sales Contingent Payment such that the Maximum Sales Contingent Amount is not exceeded, and no further Sales Contingent Payment shall be due or payable thereafter. For purposes of this Section 1.7, any amounts offset by Parent against any Sales Contingent Payments made pursuant to Section 1.8(j), Sections 2.1(a)-2.1(c), Section 2.5(e), Section 9.4 or otherwise, shall be deemed to have been paid by Parent pursuant to this Section 1.7. For clarity, amounts offset by Parent pursuant to Section 1.8(j), Sections 2.1(a)-(c), Section 2.5(e), Section 9.4 or otherwise shall be included for purposes of determining under this Section 1.7 whether Parent has paid the Maximum Sales and Licensing Consideration Contingent Amount. Notwithstanding anything herein to the contrary, Parent shall not be required to make, and the Participating Rights Holders shall not be entitled to receive, any further Sales Contingent Payments after the Sales Contingent Payments are made in connection with the Contingent Payment Termination Date in accordance with the provisions of Section 1.8.

Section 1.8 Payment of Contingent Payments.

(a) FDA Milestone Payment. On or prior to the thirtieth (30^th) day following the achievement of the FDA Milestone, Parent shall deliver to each of the Participating Rights Holders that portion of the FDA Milestone Payment Amount allocated to such Participating Rights Holder pursuant to Section 2.1.

(b) Sales Contingent Payment Amount Certificates. On or prior to the ninetieth (90^th) day following the last day of each Contingent Payment Year, Parent shall deliver to the Stockholder Representative Committee a certificate (each, a “Contingent Payment Certificate”), setting forth (a) the amount of Worldwide Net Sales for such Contingent Payment Year and (b) Parent’s determination of the Sales Contingent Payment Amount, if any, for such Contingent Payment Year.

(c) Stockholder Representative Committee Audit Rights. Parent hereby grants, and shall cause the other members of the Buyer Group to grant, the Stockholder Representative Committee and their representatives and advisers, at the Stockholder Representative Committee’s sole expense, the right, exercisable no more than once during each sixty (60) day period following the receipt by the Stockholder Representative Committee of a Contingent Payment Certificate, subject to the execution of, and compliance with, a customary confidentiality agreement in form and substance reasonably satisfactory to Parent, to examine and have full access to the Buyer Group’s books of account and records of Worldwide Net Sales for the applicable Contingent Payment Year with respect to which the most recent Contingent Payment Certificate has been delivered, as well as the immediately prior Contingent Payment Year, at the location of such records on prior written notice of at least fifteen (15) days, for the

purpose of verifying the amount of Worldwide Net Sales for such Contingent Payment Years (each such review shall be referred to herein as a “Contingent Payment Audit”). Notwithstanding the foregoing, absent fraud, intentional misconduct, or the discovery (following the completion of any Contingent Payment Audit) of a material fact in existence at the time of such Contingent Payment Audit and not made available by Parent to the Stockholder Representative Committee or its representatives in the course of conducting such Contingent Payment Audit, which material fact, if taken into account in the calculation of the applicable Sales Contingent Payment Amount, would have resulted in an increase in such Sales Contingent Payment Amount, the Stockholder Representative Committee or its representatives shall not be permitted to review any records of Worldwide Net Sales for any Contingent Payment Year for which a Contingent Payment Audit has previously been performed. For the purpose of conducting a Contingent Payment Audit, the Stockholder Representative Committee may hire, at its expense, one or more auditors or attorneys of the Stockholder Representative Committee’s choosing to assist in such examination, provided, that such auditors or attorneys have entered into customary confidentiality agreements with Parent in form and substance reasonably acceptable to Parent. The Stockholder Representative Committee and such representatives shall have access to all of the books and records required to perform any Contingent Payment Audit for a thirty (30) day period, beginning on the date on which access to substantially all of such books and records is first given to the Stockholder Representative Committee. Nothing in this Section 1.8(c) shall be deemed to require any member of the Buyer Group to keep any books of account or records other than those which they maintain in the ordinary course of business in its usual and customary practice, to retain any such books of account or records for any period in excess of the period for which they retain such records in the ordinary course of business in their usual and customary practice, or to provide access to any books and records other than that specified above, and no presumption shall be made against any member of the Buyer Group as a result of the absence of any such books and records as a result of the disposition of any such books and records in the ordinary course of business; provided, however, that in no case shall any member of the Buyer Group dispose of such books of account or records with respect to a Contingent Payment Year earlier than the date one hundred and eighty (180) days following the last day of the subsequent Contingent Payment Year or, if such Contingent Payment Year is the last Contingent Payment Year, the last day of such Contingent Payment Year; and, provided further, that once the Stockholder Representative Committee gives notice of its intention to commence a Contingent Payment Audit with respect to a Contingent Payment Year or Contingent Payment Years, the Buyer Group shall use commercially reasonable efforts to keep and retain all books of account relating to Worldwide Net Sales for the Contingent Payment Year or Contingent Payment Years for which such Contingent Payment Audit is being conducted that are identified in a request or requests from the Stockholder Representative Committee with respect to the Sales Contingent Payment Amount for such Contingent Payment Year or Contingent Payments Years.

(d) Dispute Notice. In the event that the Stockholder Representative Committee does not agree with the Sales Contingent Payment Amount set forth on any Contingent Payment Certificate, the Stockholder Representative Committee shall be entitled, during the period following delivery of such Contingent Payment Certificate and ending on the later of (i) ninety (90) days of delivery of such Contingent Payment Certificate or (ii) thirty (30) days following the completion of a Contingent Payment Audit commenced in connection with the delivery of such Contingent Payment Certificate (the “Dispute Period”), to give Parent

written notice (a “Dispute Notice”), of such disagreement. In the event that the Stockholder Representative Committee does not deliver a Dispute Notice during the Dispute Period, the Sales Contingent Payment Amount set forth on such Contingent Payment Certificate shall irrevocably be deemed to be the final Sales Contingent Payment Amount for such Contingent Payment Year and all purposes of this Agreement, absent fraud or intentional misconduct.

(e) Agreed Contingent Payment. In the event that the Stockholder Representative Committee delivers a Dispute Notice within the Dispute Period, the Stockholder Representative Committee and Parent shall for a period of not less than thirty (30) days after delivery of the Dispute Notice attempt in good faith to resolve the Sales Contingent Payment Amount that is in dispute (the “Disputed Contingent Payment Amount”), and mutually determine any adjustments to such Sales Contingent Payment Amount (the “Agreed Contingent Payment Amount”). Parent and the Stockholder Representative Committee shall, subject to the execution of a confidentiality agreement in form and substance reasonably satisfactory to the delivering party, provide each other with such information, records and material kept in the ordinary course of business in such party’s possession and which such party may disclose without violating confidentiality obligations to third parties, as is reasonably necessary and appropriate in attempting to resolve such Disputed Contingent Payment Amount, including the delivery of a copy to the Stockholder Representative Committee of any such information, records and material, to the extent then available, that was used to calculate the amount of Worldwide Net Sales and the Sales Contingent Payment Amount set forth on each relevant Contingent Payment Certificate. If the final Agreed Contingent Payment Amount determined pursuant to this Section 1.8(e) is greater than the Sales Contingent Payment Amount set forth on the relevant Contingent Payment Certificate by an amount equal to more than the greater of (i) $1,000,000 or (ii) ten percent (10%) of the Sales Contingent Payment Amount set forth in the relevant Contingent Payment Certificate, Parent shall pay all of the reasonable out-of-pocket costs and expenses actually incurred by the Stockholder Representative Committee in connection with such Contingent Payment Audit.

(f) Arbitration of Disputes. In the event that no agreement can be reached by the Stockholder Representative Committee and Parent as to the calculation of the Disputed Contingent Payment Amount within ninety (90) days after delivery of a Dispute Notice and such disagreement relates only to the amount of Worldwide Net Sales of any Contingent Payment Product, then, pursuant to this Section 1.8(f), either party shall have the right to submit the Disputed Contingent Payment Amount to arbitration by the Boston, Massachusetts office of one (1) of the following entities or their respective successors, or such other accountants as the Company and Parent may mutually agree, so long as such entity or its successors is not the principal regularly-engaged outside accountant to Parent or the Company or any auditor that may have assisted the Stockholder Representative Committee in any Contingent Payment Audit: Deloitte & Touche LLP, KPMG, Ernst & Young LLP, PricewaterhouseCoopers, BDO Xxxxxxx, LLP, Xxxxx Xxxxxxxx LLP, or any successor entity to the foregoing (collectively, the “Accountants”); provided, however, that the engagement and charge of the Accountants shall be limited to determining the Worldwide Net Sales of any identified product or products for the applicable Contingent Payment Year used to calculate the Disputed Contingent Payment Amount, and the Appraiser shall not be entitled to determine whether any products sold by Parent or its Affiliates are Contingent Payment Products for purposes of this Agreement or any other matter. The Stockholder Representative Committee and Parent shall jointly select which of

the Accountants will perform the calculation within thirty (30) days after the Stockholder Representative Committee and Parent determine that they are unable to settle the amount independently; provided, that in the event that the Stockholder Representative Committee and Parent are unable to agree upon the Accountants to perform such calculation within such thirty (30) day period, then each of the Stockholder Representative Committee and Parent shall select one of the Accountants and such Accountants shall jointly select a third Accountant to perform such calculation. The Accountants selected in accordance with the foregoing sentence shall be responsible for the determination of the Disputed Contingent Payment Amount (the “Appraiser”). The Appraiser shall determine the Disputed Contingent Payment Amount within the limitations set forth above within ninety (90) days after the date of such Appraiser’s engagement and the Appraiser shall be provided with such information and records, which may include on-site access, relating to such dispute as it may reasonably request. Any Disputed Contingent Payment Amount determined by an Appraiser in accordance with this paragraph (f) shall be deemed to be the final Sales Contingent Payment Amount for the applicable Contingent Payment Year for all purposes of this Agreement. The fees and expenses of the Appraiser shall be paid by the Stockholder Representative Committee, provided, that if the final Sales Contingent Payment Amount determined by the Appraiser in any examination conducted pursuant to this Section 1.8(f) is greater than the Sales Contingent Payment Amount set forth on the relevant Contingent Payment Certificate by an amount equal to more than the greater of (i) $500,000 or (ii) five percent (5%) of the Sales Contingent Payment Amount set forth in the relevant Contingent Payment Certificate, then Parent shall pay all of the fees and expenses of the Appraiser. If the final Sales Contingent Payment Amount determined by the Appraiser in any examination conducted pursuant to this Section 1.8(f) is greater than the Sales Contingent Payment Amount set forth on the relevant Contingent Payment Certificate by an amount equal to more than the greater of (i) $1,000,000 or (ii) ten percent (10%) of the Sales Contingent Payment Amount set forth in the relevant Contingent Payment Certificate, then Parent shall also pay all reasonable out-of-pocket costs and expenses actually incurred by the Stockholder Representative Committee in connection with any Contingent Payment Audit. Parent shall not have any right of offset with respect to any payments made pursuant to this Section 1.8(f).

(g) Final Calculation and Payment of Sales Contingent Payment. With respect to any Sales Contingent Payment Amount for any Contingent Payment Year:

(i) In the event the Stockholder Representative Committee does not deliver a Dispute Notice with respect to the Sales Contingent Payment Amount set forth on the Contingent Payment Certificate delivered for such Contingent Payment Year within the Dispute Period, or the Stockholder Representative Committee delivers to Parent a written notice (an “Agreement Notice”) informing Parent of its agreement with the Sales Contingent Payment Amount set forth on such Contingent Payment Certificate, the Sales Contingent Payment Amount set forth in the relevant Contingent Payment Certificate shall be deemed to be the final such Sales Contingent Payment Amount for such Contingent Payment Year for all purposes of this Agreement, and the Parent shall, within fifteen (15) days after such determination, pay the amounts required to be paid based on such Sales Contingent Payment Amount to the Participating Rights Holders, subject to paragraph (j) below.

(ii) In the event that the Stockholder Representative Committee delivers a Dispute Notice pursuant to Section 1.8(d) with respect to a Sales Contingent Payment

Amount, and Parent and the Stockholder Representative Committee shall mutually determine the Agreed Contingent Payment Amount, then the Agreed Contingent Payment Amount shall be deemed to be the final such Sales Contingent Payment Amount for such Contingent Payment Year for all purposes of this Agreement, absent fraud or intentional misconduct, and Parent shall, within fifteen (15) days after such Agreed Contingent Payment Amount is determined, pay the amounts required to be paid based on such Sales Contingent Payment Amount to the Participating Rights Holders, subject to paragraph (j) below.

(iii) In the event that the final Sales Contingent Payment Amount for such Contingent Payment Year is determined by an Appraiser pursuant to paragraph (f) above, then the Parent shall, within fifteen (15) calendar days after such determination, pay the amounts required to be paid based on such Sales Contingent Payment Amount to the Participating Rights Holders, subject to paragraph (j) below.

(iv) The determination of any Sales Contingent Payment Amount pursuant to Sections 1.8(g)(i), 1.8(g)(ii) or 1.8(g)(iii) shall, in the absence of fraud or intentional misconduct, be conclusive, and Parent, Stockholder Representative Committee and Appraiser shall each be free from any and all liability resultant from such determination.

(h) First Recovery Contingent Payment. Within thirty (30) days after delivery of the Contingent Payment Certificate for the first Contingent Payment Year, if any, in which the Parent reports aggregate Worldwide Net Sales equal to or greater than $110,000,000, to the extent that a First Recovery Contingent Payment becomes payable in accordance with Section 1.6(e), the Parent shall deliver to each of the Participating Rights Holders that portion of the First Recovery Contingent Payment Amount allocated to such Participating Rights Holder pursuant to Section 2.1, provided, that to the extent that the Sales Contingent Payment Amount set forth on such Contingent Payment Certificate is greater than zero, Parent shall be entitled to delay payment of the amounts due to the Participating Rights Holders in respect of the First Recovery Contingent Payment until payment of the Sales Contingent Payment for such Contingent Payment Year.

(i) Second Recovery Contingent Payment. Within thirty (30) days after delivery of the Contingent Payment Certificate for the Fourth Contingent Payment Year, to the extent that (x) such Contingent Payment Certificate or the Contingent Payment Certificate delivered for any previous Contingent Payment Year reports aggregate Worldwide Net Sales equal to or greater than $110,000,000, and (y) a Second Recovery Contingent Payment becomes payable in accordance with Section 1.6(f), the Parent shall deliver to each of the Participating Rights Holders that portion of the Second Recovery Contingent Payment Amount allocated to such Participating Rights Holder pursuant to Section 2.1, provided, that to the extent that the Sales Contingent Payment Amount set forth on the Contingent Payment Certificate for the Fourth Contingent Payment Year is greater than zero, Parent shall be entitled to delay payment of the amounts due to the Participating Rights Holders in respect of the First Recovery Contingent Payment until payment of the Sales Contingent Payment for such Contingent Payment Year.

(j) Unilateral Right of Set-Off. Subject to the express limitations set forth in Article 9 hereof, the obligation of Parent and the Surviving Corporation to make any Contingent

Payment shall be qualified by the right of Parent and the Surviving Corporation to reduce the amount of any Contingent Payment by the amount of any Damages actually incurred or suffered, or reasonably likely to be incurred or suffered, by Parent or the Surviving Corporation; provided that with respect to Damages reasonably likely to be incurred or suffered with respect to any Third-Party Claim (as defined in Section 9.3(a)), such amount shall not exceed the stated amount of such claim. In the event that Parent sets off the amount of any Contingent Payment by the amount of any Damages that have not been, at the time such Contingent Payment is made, incurred by Parent, and it is later finally determined that the full amount of such Damages will not be incurred by Parent, then, following such determination, Parent shall either, in its discretion, (i) increase the next Contingent Payment to be made by Parent by the amount of such prior reduction attributable to such Damages that will not be incurred by Parent plus interest on such amount at the “Prime Rate” as announced from time to time by Bank of America, N.A., in Charlotte, North Carolina, or its successor, from the date of such determination until the date on which such next Contingent Payment is actually paid, or (ii) pay to the Participating Rights Holders, promptly after such determination and without interest, the amount of the prior reduction attributable to such Damages that will not be incurred by Parent in the form of an additional Contingent Payment that is otherwise paid in accordance with the terms of this Agreement (but shall not be included in any calculation of the Maximum Sales Contingent Amount).

(k) Dissenting Shares. The provisions of this Section 1.8 shall also apply to Dissenting Shares that lose their status as such, except that the obligations of Parent under this Section 1.8 shall commence on the date of loss of such status and the holder of such shares shall be entitled to receive in exchange for such shares the payments to which such holder would otherwise have been entitled pursuant to Section 2.1 hereof had such shares of Company capital stock not been Dissenting Shares at the Effective Time.

(l) Assignability. The right of each Participating Rights Holder to receive Merger Consideration pursuant to this Article 1 may be assigned (i) to such Participating Rights Holder’s spouse, domestic partner, parents or parents-in-law, siblings or sibling’s in-law, or such Participating Rights Holder’s or such Participating Rights Holder’s spouse or domestic partner’s ancestors, lineal descendants or descendants by virtue of adoption, (ii) to a trust for the benefit of the Participating Rights Holder or any person named in the preceding clause (i), (iii) to another person if all or substantially all of the beneficial ownership of such person as of the date of assignment are beneficially owned by the Participating Rights Holder or any person named in the preceding clause (i), (iv) to another person, if, on the Closing Date, such other person was the beneficial owner of the shares of Company Common Stock, Company Preferred Stock, or Company Options held of record by the Participating Rights Holder, (v) to a parent, subsidiary or other affiliate of any Participating Rights Holder that is an entity or any such Participating Rights Holder’s partners, members or other equity owners, or retired partners, retired members or other equity owners, or to the estate of any of its partners, members or other equity owners or retired partners, retired members or other equity owners, or (vi) by operation of law or by will, provided, however, that the right of each Participating Rights Holder to receive Merger Consideration pursuant to this Article 1 may be assigned to no more than three (3) persons, and in no event shall Parent be required to recognize any such assignment for any purpose hereunder until the Parent has been duly notified of such assignment in a certificate to such effect executed by the members of the Stockholder Representative Committee, and receive such other

certifications and other information as the Parent may reasonably request of the assigning Participating Rights Holder and any assignees.

(m) Contingent Payments Not Royalties. The Contingent Payments provided for pursuant to this Article 1 are provided as a result of bona fide difficulties in determining the present value of the Company. The Contingent Payments represent (and shall be reported by Parent as) additional consideration for the Company Common Stock and Company Preferred Stock and are not intended to be royalty payments.

Notwithstanding the foregoing, a portion of any Contingent Payment otherwise attributable to the Company Common Stock may be deducted from such Contingent Payment and paid to the Stockholder Representative Committee as additional Committee Reimbursement Amount in accordance with Section 2.5 or made subject to the rights of Parent and the Surviving Corporation under Section 1.8(h).

(b) Preferred Stock. Each share of each series, if any, of Company Preferred Stock issued and outstanding immediately prior to the Effective Time and held by Participating Rights Holders will be converted at the Effective Time into the right to receive (i) an amount equal to the Per Share Closing Payment that would otherwise be payable with respect to the number of shares of Company Common Stock into which such share of Company Preferred Stock is convertible immediately prior to the Effective Time, (ii) the right to receive a portion of the funds deposited in escrow pursuant to Section 1.5(e) hereof, when such funds, if any, are released from escrow pursuant to the terms of the Escrow Agreement, (iii) the Per Share FDA Milestone Payment that would otherwise be payable with respect to the number of shares of

It is agreed and understood that for all purposes of this Agreement the parties will not treat as exercised (and will instead treat as outstanding unexercised Company Options) any Company Option that the holder has purported to exercise unless prior to the Effective Time (x) the holder of the Company Option has fully complied with the conditions to such exercise and the holder’s obligations with respect to such exercise as set out in the Company Option Plan, if applicable, and the applicable Company Option documentation (including without limitation by paying in full the applicable purchase price for the shares subject to that Company Option and any applicable amounts required to be paid in respect of withholding obligations under the Company Option Plan and applicable law), (y) the Company has issued a valid certificate for the shares of

Company Common Stock purchased upon exercise of that Company Option, as determined by Parent in its reasonable discretion, and (z) such shares are reflected as being outstanding on the Capitalization and Closing Payment Certificate. The Option Notice shall include specific procedures, mutually acceptable to Parent and the Company, to facilitate the exercise of Company Options as of the Effective Time.

(i) Within a reasonable period of time prior to the Closing, Parent will deliver to the Company forms of the transmittal materials which Parent or its transfer or paying agent will reasonably require from those Participating Rights Holders entitled to receive at the Closing a portion of the Closing Payment Amount in respect of their shares of Company Common Stock or Company Preferred Stock, or in respect of their Company Options, which materials may include any certifications Parent may reasonably request with respect to compliance with any withholding obligations of Parent or the Surviving Corporation under the Code. The Company will distribute such materials to eligible Participating Rights Holders. As promptly as practicable, and using commercially reasonable best efforts, immediately following the Effective Time, Parent will deliver to each Participating Rights Holder who has completed such transmittal materials and returned them to Parent at or prior to the Closing, together with the certificate or certificates representing outstanding shares of Company Common Stock or Company Preferred Stock (the “Certificates”) or certificates or instruments representing outstanding Company Options (“Derivative Instruments”), a check (or, at the Participating Rights Holder’s election, a wire transfer to the extent that the aggregate amount owed to any such holder at the Closing is in excess of $1,000,000) representing that portion of the Closing Payment Amount to which such Participating Rights Holder is entitled; provided, that such payment made by Parent by check may be made by delivering such checks on the Closing Date to the Stockholder Representative Committee, which, in turn, shall distribute such checks to the appropriate Participating Rights Holders. The delivery of such checks (or wire transfers, as applicable) by Parent to the Stockholder Representative Committee or the Participating Rights Holder, as applicable, shall be deemed, for all purposes, to have satisfied in full Parent’s obligation to make payment of the Closing Payment Amount to such Participating Rights Holders and Parent shall have no further obligation for such payments. Parent shall not be required to pay any amount of the Closing Payment Amount or any Contingent Payment to any Participating Rights Holder until receipt from such Participating Rights Holder of properly completed and executed transmittal materials in the form prepared by Parent. Parent shall be entitled to rely entirely on the information contained in the Capitalization and Closing Payment Amount Certificate and any transmittal materials delivered hereunder for purposes of satisfying Parent’s obligation to deliver the Closing Payment Amount and any Contingent Payment hereunder. Without limiting any of the obligations of Parent hereunder with respect to such payments, Parent shall be entitled to engage a transfer or paying agent to make payment of the respective payments required to be made by Parent or the Surviving Corporation to the Participating Rights Holders hereunder on Parent’s behalf.

(ii) As promptly as practicable after the Effective Time, but not later than ten (10) days after the Effective Time, Parent or a transfer or exchange agent engaged by Parent will send to each Participating Rights Holder who does not submit completed transmittal

materials to Parent at or before the Closing, as permitted by Section 2.2(a)(i) above, transmittal materials for use in exchanging his, her or its Certificates or Derivative Instruments for the applicable portion of the Closing Payment Amount (and any Contingent Payments) into which such shares of Company Common Stock or Company Preferred Stock (other than any Dissenting Shares) or Company Options, have been converted. Until surrendered as contemplated by this Section 2.2, each Certificate or Derivative Instrument shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the applicable amounts of Merger Consideration payable pursuant to Section 2.1. Upon receipt of the completed transmittal materials and the applicable Certificates and Derivative Instruments, Parent will deliver to the Participating Rights Holder a check (or, at the Participating Rights Holder’s election, a wire transfer, to the extent that the aggregate amount owed to such Participating Rights Holder as of the Closing is in excess of $1,000,000) representing that portion of the Closing Payment Amount to which such Participating Rights Holder is entitled.

(iii) Lost Certificates and Derivative Instruments. The transmittal materials referenced above shall provide that, in the event that any Certificates or Derivative Instruments have been lost, stolen or destroyed, the Participating Rights Holder thereof may deliver a customary form of lost certificate affidavit of that fact by the holder thereof together with an agreement to indemnify and hold harmless the Parent for any losses in connection therewith, and the posting of a bond in customary amount if required by any paying agent engaged by Parent, and upon such delivery the Parent shall issue in exchange for such lost, stolen or destroyed Certificates the Merger Consideration payable with respect thereto pursuant to Section 2.1.

(b) No Further Rights in Certificates or Derivative Instruments. From and after the Effective Time, holders of Company Common Stock, Company Preferred Stock or Company Options outstanding immediately prior to the Effective Time will cease to be, and will have no rights as, stockholders or rightholders of the Company or the Surviving Corporation, other than (i) in the case of Company Common Stock and Company Preferred Stock (other than Dissenting Shares), and Company Options, the rights to receive the applicable portions of the Merger Consideration to be issued at Closing, of the funds deposited in escrow and of the Contingent Payments; (ii) in the case of Dissenting Shares, the rights afforded to the holders thereof under Section 262 of Delaware Law or Sections 1300-1312 of California Law, as applicable, and (iii) rights under this Agreement and the Escrow Agreement.

(c) No Liability. Neither Parent, the Surviving Corporation nor the Company shall be liable to any holder of Company Common Stock, Company Preferred Stock or Company Options for any portion of the Merger Consideration or the funds deposited in escrow delivered to an appropriate public official pursuant to the requirements of any abandoned property, escheat or similar law.

(d) Withholding Rights. Each of the Surviving Corporation, Parent and Escrow Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement or the Escrow Agreement to any holder of Company Common Stock, Company Preferred Stock or Company Options such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign Tax law. To the extent that amounts are so withheld by the Surviving

Corporation, Parent or Escrow Agent, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to such holder in respect of which such deduction and withholding was made by the Surviving Corporation, Parent or Escrow Agent, as the case may be.

Section 2.3 Stock Transfer Books. At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers of Company Common Stock or Company Preferred Stock thereafter on the records of the Company.

Section 2.4 Dissenting Shares.

(a) Notwithstanding any provision of this Agreement to the contrary, shares of Company Common Stock or Company Preferred Stock that are outstanding immediately prior to the Effective Time and which are held by stockholders who shall have not voted in favor of the Merger or consented thereto in writing and who shall have exercised dissenters’ rights or rights of appraisal for such shares of Company Common Stock or Company Preferred Stock in accordance with Delaware Law or California Law, if any, and who, as of the Effective Time, have not effectively withdrawn or lost such dissenters’ rights (collectively, the “Dissenting Shares”), shall not be converted into or represent the right to receive any portion of the amounts to be paid pursuant to Section 2.1 or under the Escrow Agreement, but the holders thereof shall only be entitled to such rights as are granted by Delaware Law or California Law, if any. All Dissenting Shares held by stockholders who shall have failed to perfect or who effectively shall have withdrawn or lost their dissenters’ rights shall thereupon be deemed to have been converted into and to have become exchangeable for, as of the later of the Effective Time or the occurrence of such event, the right to receive an appropriate portion of the amounts to be paid pursuant to Section 2.1 or under the Escrow Agreement, without any interest thereon, upon surrender, in the manner provided in Section 2.2, of the Certificates that formerly evidenced such shares.

(b) The Company shall give Parent (i) prompt notice of any demands for fair value of shares of Company Common Stock or Company Preferred Stock received by the Company, withdrawals of such demands, and any other instruments served pursuant to Delaware Law or California Law, if any, and received by the Company, and (ii) the opportunity to direct all negotiations and proceedings with respect to demands for fair value under Delaware Law or California Law, if any. The Company shall not, except with the prior written consent of Parent, make any payment with respect to any demands for the fair value of shares of Company Common Stock or Company Preferred Stock or settle or offer to settle any such demands other than by operation of law or pursuant to a final order of a court of competent jurisdiction.

Section 2.5 Stockholder Representative Committee.

(a) Appointment of Stockholder Representative Committee. Upon approval of the Merger by the Company Stockholders, each of the Participating Rights Holders shall be deemed to have constituted and appointed, effective from and after the date of such approval of the Merger, each of Xxxxxxx Xxxxx, Xxxxx Xxxxxxxx and Xxxx Xxxxxxxxxx or their successors or replacements, as determined by the Company prior to the Effective Time, or a majority-in-interest of the Participating Rights Holders following the Effective Time, as the agents and

attorneys-in-fact (the “Stockholder Representative Committee”) of such Participating Rights Holders to act as the Stockholder Representative Committee under this Agreement in accordance with the terms of this Section 2.5 and the Escrow Agreement. In the event of the resignation, removal, death or incapacity of a member of the Stockholder Representative Committee, a successor member shall thereafter be appointed by an instrument in writing signed by such successor member and by the remaining members of the Stockholder Representative Committee, and such appointment shall become effective as to any such successor member when a copy of such instrument shall have been delivered to Parent. Any member of the Stockholder Representative Committee may be removed by action of those Participating Rights Holders who immediately prior to the Effective Time of the Merger held a majority of the outstanding shares of Company Common Stock and Company Preferred Stock held by all Participating Rights Holders, on an as-if fully-converted basis (other than Dissenting Shares). So long as there are more than two members of the Stockholder Representative Committee, the Stockholder Representative Committee shall act by majority vote in accordance with such procedures as it may adopt (otherwise, a unanimous vote shall be required). Notwithstanding the foregoing, unless Parent and the Surviving Corporation shall have actual knowledge that Xxxxxxx Xxxxx has not obtained the authority of the Stockholder Representative Committee with respect to any action or inaction, Parent and the Surviving Corporation shall be entitled to rely, without any investigation or inquiry, upon all action or inaction by Xxxxxxx Xxxxx as having been taken or not taken upon the authority of the Stockholder Representative Committee; provided, that a majority of the members of the Stockholder Representative Committee shall be entitled at any time to designate another member of the Stockholder Representative Committee as the designated representative for the Stockholder Representative Committee for this purpose.

(b) Authority After the Effective Time. From and after the Effective Time, the Stockholder Representative Committee shall be authorized to:

(i) take all actions required by, and exercise all rights granted to, the Stockholder Representative Committee in this Agreement or the Escrow Agreement;

(ii) receive all notices or other documents given or to be given to the Stockholder Representative Committee by Parent pursuant to this Agreement or the Escrow Agreement;

(iii) receive and accept service of legal process in connection with any claim or other proceeding against the Participating Rights Holders or the Company arising under this Agreement or the Escrow Agreement;

(iv) negotiate, undertake, compromise, defend, resolve and settle any suit, proceeding or dispute under this Agreement or the Escrow Agreement;

(vi) participate in and manage the defense of any Third-Party Claims, consult with Parent as to the defense of any Parent-Handled Claims, approve or withhold

approval of proposed settlements of any Third-Party Claims, and take such other actions on behalf of the Participating Rights Holders as may be necessary or appropriate under Article IX of this Agreement;

(vii) execute and deliver all agreements, certificates and documents required or deemed appropriate by the Stockholder Representative Committee in connection with any of the transactions contemplated by this Agreement (including executing and delivering the Escrow Agreement);

(viii) engage special counsel, accountants and other advisors and incur such other expenses in connection with any of the transactions contemplated by this Agreement or the Escrow Agreement;

(ix) apply the Committee Reimbursement Amount to the payment of (or reimbursement of the Stockholder Representative Committee for) expenses and liabilities which the Stockholder Representative Committee may incur pursuant to this Section 2.5;

(x) cause additional amounts to be withheld from Contingent Payments to the extent the Stockholder Representative Committee deems it necessary to maintain an adequate amount of funds in the Committee Reimbursement Amount to cover expenses of the Stockholder Representative Committee and, under the circumstances described in Sections 1.8(f) and 6.9(e)(vi), the Parent, up to a maximum of $250,000 at any given time; and

(xi) take such other action as the Stockholder Representative Committee may deem appropriate, including:

(A) agreeing to any modification or amendment of this Agreement or the Escrow Agreement in accordance with the terms hereof and thereof and executing and delivering an agreement of such modification or amendment;

(B) taking any actions required or permitted under the Escrow Agreement to protect or enforce the Participating Rights Holders’ rights thereunder; and

(C) all such other matters as the Stockholder Representative Committee may deem necessary or appropriate to carry out the intents and purposes of this Agreement and the Escrow Agreement.

(c) Reimbursement of Expenses. The members of the Stockholder Representative Committee shall be entitled to receive reimbursement from any Committee Reimbursement Amount retained on behalf of the Stockholder Representative Committee and then, immediately prior to its distribution to the Participating Rights Holders, against the consideration held pursuant to the Escrow Agreement, for any and all expenses, charges and liabilities, including reasonable attorneys’ fees, incurred by the Stockholder Representative Committee in the performance or discharge of its rights and obligations under this Agreement (the “SRC Expenses”). In the event that the obligations of the Stockholder Representative Committee require that the members of the Stockholder Representative Committee consistently spend significant business time over the course of several months in connection with indemnification claims made pursuant to Article 9 hereof, the Stockholder Representative

Committee shall be entitled to a one-time payment out of the Committee Reimbursement Amount in the aggregate amount of $50,000, which amount will be considered an SRC Expense for purposes hereof. The Committee Reimbursement Amount shall only be used for the payment of the SRC Expenses or as otherwise required by this Agreement. The Parent and its Affiliates shall have no obligations whatsoever with respect to any SRC Expenses.

(d) Release from Liability; Indemnification; Authority of Stockholder Representative Committee. Each Participating Rights Holder hereby releases the Stockholder Representative Committee, and each of its members, from, and each Participating Rights Holder agrees to indemnify the Stockholder Representative Committee, and each of its members, against, liability for any action taken or not taken by him, her or it in his, her or its capacity as such agent, except for the liability of the Stockholder Representative Committee, or any member thereof, to a Participating Rights Holder for loss which such holder may suffer from the willful misconduct or gross negligence of the Stockholder Representative Committee or such member in carrying out his, her or its duties hereunder. By virtue of the adoption of this Agreement and the approval of the Merger by the stockholders of the Company, each Participating Rights Holder (regardless of whether or not such Participating Rights Holder votes in favor of the adoption of the Agreement and the approval of the Merger, whether at a meeting or by written consent in lieu thereof) appoints, as of the date of this Agreement, the Stockholder Representative Committee as his, her or its true and lawful agent and attorney-in-fact to enter into any agreement in connection with the transactions contemplated by this Agreement, to exercise all or any of the powers, authority and discretion conferred on him under any such agreement, to give and receive notices on their behalf and to be his, her or its exclusive representative with respect to any matter, suit, claim, action or proceeding arising with respect to any transaction contemplated by any such agreement, including, without limitation, the defense, settlement or compromise of any claim, action or proceeding for which Parent or the Surviving Corporation may be entitled to indemnification and, by virtue of its approval of the Agreement, the Stockholder Representative Committee agrees to act as, and to undertake the duties and responsibilities of, such agent and attorney-in-fact. All actions, decisions and instructions of the Stockholder Representative Committee shall be conclusive and binding upon all of the Participating Rights Holders.

(e) Reduction of Contingent Payments to Replenish Committee Reimbursement Amount. The Stockholder Representative Committee, upon written notice delivered to Parent no less than twenty (20) business days prior to the making of any Contingent Payment, including the FDA Milestone Payment, shall be entitled to cause Parent to deduct amounts from that portion of such Contingent Payment that is not subject to reduction in accordance with Sections 1.8(j), 2.1(a), 2.1(b), 2.1(c) and 9.4 for purposes of replenishing the Committee Reimbursement Amount hereunder (which Committee Reimbursement Amount may be increased from time to time in the discretion of the Stockholder Representative Committee, but not above $250,000 at any one time). Any reduction from the consideration held pursuant to the Escrow Agreement or any offset against any Contingent Payment shall be made against the amounts to be distributed to the Participating Rights Holders pro rata based on the aggregate amounts of such escrowed consideration or Contingent Payment otherwise to be received by such Participating Rights Holders. In connection with any such offsets by Parent pursuant to this Section 2.5(e), the Stockholder Representative Committee hereby releases Parent from, and agrees to indemnify Parent against, liability for any action taken by Parent at the direction of the Stockholder Representative Committee in accordance with this Section 2.5(e). Any of the

Committee Reimbursement Amount originally deposited with the Stockholder Representative Committee pursuant to this Section 2.5(e) that has not been consumed by the Stockholder Representative Committee pursuant to the terms of this Agreement on or prior to the end of the period in which Parent, the Surviving Corporation and their Affiliates may make claims for indemnification pursuant to Section 9.2 or, if later, the date on which all indemnification claims of Parent, the Surviving Corporation or any of their Affiliates outstanding at the end of such period have been discharged in full, shall be distributed by the Stockholder Representative Committee to the Participating Rights Holders pro rata based on their respective rights to participate in the first Contingent Payment, if any, from which any such amounts were originally deducted.

The Company and its subsidiaries will, and will direct their respective officers, directors, Affiliates, employees, investment bankers, attorneys and other advisors and representatives to, immediately cease any and all existing activities, discussions or negotiations with any parties conducted heretofore with respect to any Acquisition Proposal.

(b) In addition to the obligations of the Company set forth in Section 6.6(a), the Company as promptly as practicable shall advise Parent in writing of any Acquisition Proposal or of any request for nonpublic information or other inquiry which the Company reasonably believes could lead to an Acquisition Proposal, the material terms and conditions of such Acquisition Proposal (to the extent known), and the identity of the person or group making any such request, inquiry or Acquisition Proposal. The Company agrees to keep Parent informed on a current basis of the status and details (including any material amendments or proposed amendments) of any such request, inquiry or Acquisition Proposal.

Section 6.7 Full Access. At all times until the termination or expiration of this Agreement, the Company will afford to Parent and its authorized representatives, upon reasonable notice, full access during normal business hours to all properties, books, records, contracts and documents of the Company as Parent and such authorized representatives may reasonably request and a complete opportunity to make such investigations as Parent and such authorized representatives reasonably request, and the Company will furnish or cause to be furnished to Parent and its authorized representatives all such information with respect to the affairs and businesses of the Company as they may reasonably request. All information obtained by Parent pursuant to this Section 6.7 shall be kept confidential in accordance with that certain Non-Disclosure Agreement, dated March 10, 2004, between Parent and the Company (the “Confidentiality Agreement”). No investigation pursuant to this Section 6.7 shall affect any representation or warranty in this Agreement of any party hereto or thereto or any condition to the obligations of the parties hereto or thereto.

Section 6.8 Public Announcements. Prior to the closing of the Merger, Parent shall not, without having previously informed the Company about the form, content and timing of any such announcement, issue any press release or otherwise make any public statements with respect to this Agreement or the transactions contemplated hereby, except as may be required by (a) law, (b) the Securities Exchange Commission, (c) the Securities Act, or the Exchange Act, or (d) any listing agreement with the NASDAQ Stock Market. Nothing

herein express or implied shall require Parent to consult with the Company following the closing of the Merger.

From and after the date of this Agreement until the Effective Time or termination of this Agreement, the Company shall (a) maintain at least one (1) pending United States patent application in each independent patent family of the Company Intellectual Property, (b) not abandon or allow to be abandoned any patent applications of the Company pending as of the Agreement Date, (c) take any and all such actions as may be commercially reasonable to cause each patent of the Company to be valid and subsisting, including paying all necessary registration, maintenance and renewal fees in connection with such patents and filing all necessary documents and certificates in connection with such patents with the relevant authorities in the United States or foreign jurisdictions, as the case may be, for the purposes of maintaining such patents in full force and effect, and (d) use commercially reasonable efforts to continue to acquire and develop additional Intellectual Property useful to the Principal Business consistent with its ordinary course of business.

Section 6.10 Certain Obligations of Parent.

(a) During the period from the Closing Date until the achievement of the FDA Milestone, Parent shall use commercially reasonable efforts to achieve the FDA Milestone as soon as reasonably practicable including taking those commercially reasonable actions required or otherwise requested by the FDA, or any successor entity, to achieve the FDA Milestone. However, the parties acknowledge that despite Parent’s use of commercially reasonable efforts in accordance with this Section 6.10, circumstances may exist that delay or prevent the achievement of the FDA Milestone. Accordingly, nothing herein shall be deemed to be an agreement on the part of Parent to achieve the FDA Milestone within any period of time, or at all. Without limiting the foregoing, Parent shall be required to answer reasonable inquiries of the Stockholder Representative Committee with respect to the prosecution of any application with the FDA, or any successor entity, intended to achieve the FDA Milestone and (i) promptly provide to the members of the Stockholder Representative Committee copies of any material written correspondence received from the FDA with respect thereto, and (ii) no later than ten (10) business days prior to the filing thereof provide to the members of the Stockholder Representative Committee any proposed application or written correspondence to the FDA with respect thereto, including copies of any and all underlying data to accompany any such application or correspondence. Parent shall consider in good faith any comments of the members of the Stockholder Representative Committee on any such proposed application or

written correspondence which are delivered to Parent a reasonable time prior to the proposed filing thereof. Parent shall also notify the members of the Stockholder Representative Committee of any meetings with the FDA with respect to such application.

(b) During the period between the achievement of the FDA Milestone and the Contingent Payment Termination Date, (i) Parent shall not, and shall cause each member of the Buyer Group to not, take any actions in bad faith in the marketing and sale of Contingent Payment Products, and the operation of the Surviving Corporation which could reasonably be expected to have the effect of avoiding the Parent’s obligations to make the Contingent Payments hereunder, (ii) Parent agrees, and shall cause each member of the Buyer Group to agree, to use its commercially reasonable efforts, consistent with its ordinary course of conduct, to market and sell Contingent Payment Products, and (iii) the Parent shall, and shall cause each member of the Buyer Group to, not discontinue the sale of any Contingent Payment Product during the period between the Effective Time and the Contingent Payment Termination Date unless it determines in good faith that it would be commercially reasonable to do so; provided, however, that from and after the occurrence of a Pregnancies Event, the Parent shall not be required to comply with clauses (ii) and (iii) above. Moreover, whether certain efforts by Parent to market and sell any Contingent Payment Product are deemed to be “commercially reasonable” in accordance with clause (ii) above shall be determined in light of, and in making the determination set forth in clause (iii) above, Parent shall be entitled to consider, all relevant factors, taken as a whole, including without limitation the level of development of such Contingent Payment Product, the perceived market potential of such Contingent Payment Product in each relevant jurisdiction, the level of regulatory approval for such Contingent Payment Product (if applicable) in each jurisdiction (including, but not limited to, the extent of the indications for which such Contingent Payment Product has been approved, if applicable), whether or not the sale of such Contingent Payment Product could infringe the Intellectual Property rights of third parties and, if so, the likelihood thereof, the relative profitability of such Contingent Payment Product, including as to gross and net margins, the availability of raw materials and components for such Contingent Payment Product (if applicable), and the competitive position of such product vis-à-vis other products that may be marketed and sold in each jurisdiction for the same or similar indications or uses, including with respect to the efficacy, safety and cost of such Contingent Payment Product when compared to such other products. The efforts required by Parent under this Section 6.10 shall be measured in relation to the efforts historically undertaken by Parent as of the Effective Time with respect to products of similar market potential, and shall take into account Parent’s financial and sales and marketing related resources from time to time. In connection with its obligations under this paragraph (a), Parent shall be required to designate an individual representative of Parent involved in the organization, development and management of development activities for the Contingent Payment Products who will be available for reasonable communications, on no more than a quarterly basis, with the members of the Stockholder Representative Committee regarding the development of Contingent Payment Products during the period between the achievement of the FDA Milestone and the Contingent Payment Termination Date. Notwithstanding the foregoing, the Parent’s efforts and decisions shall be deemed to be “commercially reasonable” for all purposes of this Section 6.10 in any event if (w) with respect to efforts and decisions made in the First Contingent Payment Year, Worldwide Net Sales recorded for such First Contingent Payment Year are equal to or greater than $9,000,000, (x) with respect to efforts and decisions made in the Second Contingent Payment Year, Worldwide Net Sales recorded for such Second Contingent Payment Year are equal to or greater

than $22,000,000, (y) with respect to efforts and decisions made in the Third Contingent Payment Year, Worldwide Net Sales recorded for such Third Contingent Payment Year are equal to or greater than $36,000,000, and (z) with respect to efforts and decisions made in the Fourth Contingent Payment Year, Worldwide Net Sales recorded for such Fourth Contingent Payment Year are equal to or greater than $45,000,000. Notwithstanding anything to the contrary in this Agreement, (A) the “safe harbor” provisions set forth in the preceding sentence are not intended to set minimum standards of performance by the Parent, and the Parent shall be entitled to demonstrate that its marketing and selling efforts with respect to the Contingent Payment Products may be deemed to be commercially reasonable, in the absence of the achievement of the levels of Worldwide Net Sales described above, and (B) in no event shall Parent or any successor entity of an Acquisition Transaction be required to market or sell Contingent Payment Products in any jurisdiction where neither the Buyer Group nor such successor entity, as applicable, has had, at any time since the Effective Date, a direct or indirect sales force. Notwithstanding anything to the contrary, in no event shall the engagement by Parent or any other member of the Buyer Group of a distributor to promote, market or sell any Contingent Payment Products in any jurisdiction, where such engagement would otherwise be commercially reasonable in light of all relevant circumstances, be deemed to be undertaken in bad faith in contravention of this Section 6.10.

Section 6.11 Change of Control of Parent; Sale of Assets. In the event that, during the period between the Effective Time and the Contingent Payment Termination Date, there occurs a Parent Change of Control, or a sale of a majority of the assets of the Company or of Company’s Intellectual Property as of Closing Date (any such transaction, an “Acquisition Transaction”), then the Parent shall be required to cause the successor entity of such Acquisition Transaction to specifically agree with the Stockholder Representative Committee (on behalf of the Participating Rights Holders):

(a) to assume all of the obligations of the Parent and Surviving Corporation hereunder, including pursuant to Section 6.10 with respect to any unpaid Contingent Payments (with appropriate adjustments to reflect the succession and the substitution of such successor or assignee to the obligations of Parent and Surviving Corporation hereunder); and

(b) to increase the amount of the Sales Contingent Payment Amount for the final Contingent Payment Year by an amount equal to the Catch-Up Contingent Payment, if greater than zero, to the Participating Rights Holders.

(i) “Accrued Contingent Payment Amount” means, as of the last day of the final Contingent Payment Year, the sum of the aggregate amount of all Sales Contingent Payment Amounts for all of the previously completed Contingent Payment Years, plus the Sales Contingent Payment Amount for the final Contingent Payment Year (prior to any increase in accordance with the terms of paragraph (b) above.

(ii) “Base Annual Amount” means an amount equal to: (A) $78,000,000 if an Acquisition Transaction occurs prior to the first commercial sale of a

Company Product by Parent to an unaffiliated purchaser in the United States after the Effective Time; (B) $65,000,000 if an Acquisition Transaction occurs after the first commercial sale of a Company Product by Parent to an unaffiliated purchaser in the United States after the Effective Time, but before the end of the First Contingent Payment Year; (C) $52,000,000 if an Acquisition Transaction occurs after the end of the First Contingent Payment Year, but before the end of the Second Contingent Payment Year; (D) $39,000,000 if an Acquisition Transaction occurs after the end of the Second Contingent Payment Year, but before the end of the Third Contingent Payment Year; and (E) $26,000,000 if an Acquisition Transaction occurs after the end of the Third Contingent Payment Year, but before the end of the Fourth Contingent Payment Year.

(iii) “Catch-Up Contingent Payment” means an amount equal to the Base Annual Amount minus the Accrued Contingent Payment Amount, if such result is greater than zero. In the event that the Accrued Contingent Payment Amount is greater than the Base Annual Amount, then the Catch-Up Contingent Payment shall be equal to zero.

Section 6.12 Employment Matters. Following the Effective Time, Parent, in its sole discretion, will either (a) continue (or cause the Company to continue) to maintain the Employee Benefit Plans on substantially the same terms as in effect immediately prior to the Effective Time, or (b) arrange for each participant (including, without limitation, all dependents) in the Employee Benefit Plans (the “Company Participants”) to participate in a substantially similar plans or arrangements, as determined on a plan-by-plan or arrangement-for-arrangement basis, of Parent or its applicable subsidiary (“Parent Plans”), or (c) a combination of clauses (a) and (b) so that each Company Participant shall have benefits that are substantially similar in the aggregate to benefits provided to similarly situated employees of Parent under Parent Plans and in each case at least equivalent to the benefits provided to each the Company Participant under the Employee Benefit Plans prior to the Effective Time. For purposes of determining eligibility to participate, vesting and entitlement to benefits where length of service is relevant (including for purposes of vacation accrual) under Parent Plans and other benefit arrangements of Parent (excluding a defined benefit plan), to the extent the Company Participants participate in the Parent Plans and other benefit arrangements of Parent following the Closing Date, (i) each the Company Participant will receive credit for purposes of eligibility to participate and vesting under such for years of service with the Company (or any of its subsidiaries or predecessors) prior to the Closing Date, and (ii) Parent will cause any and all pre-existing condition limitations, eligibility waiting periods and evidence of insurability requirements under any Parent Plans that are group health plans in which such the Company Participants will participate to be waived and will provide credit for any co-payments and deductibles prior to the Closing Date for purposes of satisfying any applicable deductible, out-of-pocket or similar requirements under any such plans that may apply after the Closing Date.

Section 6.13 Indemnification.

(a) Parent and Merger Sub agree that all rights to exculpation, indemnification and advancement of expenses now existing in favor of the current or former directors, officers or employees, as the case may be, of the Company as provided in the certificate of incorporation or bylaws of the Company in effect immediately prior to the Effective Time or in any indemnification agreement with such directors, officers or employees which is identified on the

Company Disclosure Schedule shall survive the Merger and shall continue in full force and effect.

(b) The provisions of this Section 6.13 shall survive the consummation of the Merger and expressly are intended to benefit, and are enforceable by, each of the parties entitled to indemnification hereunder. In the event Parent, the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any person, then, and in either such case, to the extent necessary, proper provision shall be made so that the successors and assigns of Parent or the Surviving Corporation, as the case may be, shall assume the obligations set forth in this Section 6.13.

(b) any of the following which arise at any time up to and including the Closing Date (regardless of any disclosure on the Company Disclosure Schedule): (i) any obligation or liability of the Company to any employee, former employee or beneficiary of any

Employee Benefit Plan, including those arising in connection with or by virtue of the employment up to and including the Closing Date or termination of employment of any such employee or former employee by the Company prior to the Closing Date (collectively, “Benefit Claims”); (ii) any actual or alleged liability of the Company, the Surviving Corporation or any of its Affiliates for death or injury to person or property as a result of any actual or alleged defect in any product manufactured or sold by the Company or any of its Affiliates at or prior to the Effective Time, or any actual or alleged warranty, recall or similar liability for any product sold by or for the Company at or prior to the Effective Time, or any statutory liability of the Company, the Surviving Corporation or any of its Affiliates or any liability of the Company, the Surviving Corporation or any of its Affiliates assessed with respect to any failure to warn arising out of products sold at or prior to the Effective Time (collectively, “Product Liability Claims”); (iii) any liability of the Company, the Surviving Corporation or any of its Affiliates under any Environmental Laws relating to any occurrences at or prior to the Effective Time (collectively, “Environmental Claims”); or (iv) any of the matters described in Sections 3.6 and 3.13 of the Company Disclosure Schedule (the “Known Claims”);

(c) any payments made by Parent, the Merger Sub or the Surviving Corporation after the Effective Time with respect to any Dissenting Shares to the extent that such payments exceed the portion of the Closing Payment Amount to which the holders of such Dissenting Shares would have been entitled had such Dissenting Shares not been Dissenting Shares, with any claims made pursuant to this Section 9.2(c) being referred to hereafter sometimes as the “Appraisal Claims”;

(d) regardless of any disclosure on the Company Disclosure Schedule, any claim, allegation or assertion that the development, manufacture, marketing, distribution or sale of any Company Product by Parent or the Surviving Corporation infringes or violates any Intellectual Property or other proprietary rights of any third party, except to the extent that such infringement or violation is caused by an improvement or modification to such Company Product made by Parent after the Effective Time (other than any improvement or modification specifically contemplated by the Company prior to the Effective Time or is described in, or covered by, any claims of any patents or patent applications included in the Company Owned Intellectual Property or Company Licensed Intellectual Property) to the extent that the Company Product, absent such improvement or modification, would not so infringe such Intellectual Property or other proprietary rights (collectively “Intellectual Property Claims”);

(e)(i) any breach of any representation or warranty in Section 3.14 of this Agreement or any covenant in Sections 5.1(q), 5.5 or 7.2(j) of this Agreement and (ii) to the extent not duplicative of clause (i), any actual or asserted liability for Taxes of or owed by the Company or any Subsidiary of the Company in respect of any full or partial Tax period ending on or prior to the Closing Date (claims for indemnification under this Section 9.2(e) are referred to herein as “Tax Claims”); provided, that for purposes of applying this Section 9.2(e), Parent and the Company shall use appropriate methods to allocate liability in respect of any Taxes of the Company or any Subsidiary of the Company attributable to any Tax period that includes but ends after the Closing Date (each, a “Straddle Period”), which appropriate methods shall include the following:

(A) for any income Taxes or transactional Taxes, including Taxes based on sales or revenue, the allocation of Taxes to pre- and post-Closing portions of a Straddle Period shall be determined using a closing-of-the-books method assuming that the applicable Straddle Period consists of two Taxable periods, one ending at the close of the Closing Date and one beginning at the opening of the day after the Closing Date, and

(B) for any Taxes based on net worth, capital, intangibles, or similar items, and for any real estate Taxes or other property or tangible asset-based Taxes, the allocation of Taxes to pre- and post-Closing portions of a Straddle Period shall be determined on a per-diem basis taking into account the number of days in the Straddle Period through and including the Closing Date and the number of days in the entire Straddle Period;

(f) regardless of any disclosure on the Company Disclosure Schedule, any claims made by any Company Stockholder based upon any alleged breach of fiduciary or other duty by any officer, director or stockholder of the Company in connection with this Agreement or the transactions contemplated hereby, or any claims by any officer, director or Company Stockholder to indemnification by the Company or the Surviving Corporation with respect to any such claims (collectively, “Fiduciary Duty Claims”);

(g) regardless of any disclosure on the Company Disclosure Schedule, any amounts required to discharge any Indebtedness of the Company as of the Closing Date in excess of the amount thereof set forth on the Capitalization and Closing Payment Amount Certificate (“Indebtedness Claims”);

(h) regardless of any disclosure on the Company Disclosure Schedule, any amounts required to discharge any accrued and unpaid vacation obligations of the Company outstanding as of the Closing Date in excess of the amount thereof set forth on the Capitalization and Closing Payment Amount Certificate (“Accrued Vacation Claims”);

(i) regardless of any disclosure on the Company Disclosure Schedule, any amounts required to discharge any Transaction Costs as of the Closing Date in excess of the amount thereof set forth on the Capitalization and Closing Payment Amount Certificate (“Transaction Cost Claims”);

(k) regardless of any disclosure on the Company Disclosure Schedule, any shortfall in Cash On-Hand Amount set forth in the Capitalization and Closing Payment Amount Certificate (“Shortfall Claims”); or

(l) regardless of any disclosure on the Company Disclosure Schedule, the treatment as an “excess parachute payment” (within the meaning of Code Section 280G(b)) of any payment made by the Company on or prior to the Closing Date or otherwise required to be paid by the Company, the Surviving Corporation or their respective affiliates before, on or after

the Closing Date pursuant to written or oral contracts or agreements entered into on or prior to the Closing Date (“Excess Parachute Claims”).

Without limiting the foregoing, in addition to the individual indemnification obligations of the Participating Rights Holders set forth herein, the ability of Parent and the Surviving Corporation to recover for any Damages under this Section 9.2 shall represent an express contract right to seek recovery under the Escrow Agreement in accordance with the terms thereof, and to reduce the amount of any Contingent Payment, if any, in accordance with Section 1.8(j), and nothing in this Article 9 shall be deemed to require Parent or the Surviving Corporation to obtain jurisdiction over any Participating Rights Holder, or pursue any process in connection therewith beyond that expressly required by the terms of the Escrow Agreement or Section 9.3 below. Parent’s and the Surviving Corporation’s rights of recovery hereunder are severable and distinct, provided, that in no event shall Parent or the Surviving Corporation be entitled to recover the same Damages more than once under all of such sections. Notwithstanding anything contained in this Agreement to the contrary, in the event that Parent and/or the Surviving Corporation are unable to exercise their rights of indemnification and set-off under Section 1.8(j) and this Section 9.2 or under the Escrow Agreement against any Participating Rights Holder (a “Disqualified Participating Rights Holder”) for any reason, then in each such case the other Participating Rights Holders shall indemnify Parent and/or the Surviving Corporation against that portion of such indemnification and set-off. Each such obligation of the other Participating Rights Holders may be satisfied by recovery of such amounts under the Escrow Agreement or by a further reduction in the amount of any Contingent Payment otherwise payable to such other Participating Rights Holders hereunder. The portion of such Disqualified Participating Rights Holder’s indemnification obligation that each other Participating Rights Holder shall assume hereunder shall be proportionate to that portion of the Escrowed Funds that such Participating Rights Holder would otherwise be entitled to receive upon a distribution of the Escrowed Funds (in the event of any recovery of such indemnification obligation of the Disqualified Participating Rights Holder pursuant to the Escrow Agreement), when measured against the amounts of such Escrowed Funds that all other Participating Rights Holders (other than any Disqualified Participating Rights Holder) would otherwise be entitled to receive upon a distribution of the Escrowed Funds, or that portion of the Contingent Payment such Participating Rights Holder would otherwise be entitled to receive (in the event of a reduction and off-set against a Contingent Payment in accordance with Section 1.8(j) and this Section 9.2), when measured against the amounts of such Contingent Payment that all other Participating Rights Holders (other than any Disqualified Participating Rights Holder) would otherwise be entitled to receive.

Section 9.3 Third-Party Claims.

(a) In the event that any Indemnified Party desires to make a claim against an Indemnifying Party (which term shall be deemed to include all Indemnifying Parties if more than one) in connection with any third-party litigation, arbitration, action, suit, proceeding, claim or demand at any time instituted against or made upon it for which it may seek indemnification hereunder (a “Third-Party Claim”), the Indemnified Party will promptly notify the Indemnifying Party (or, if the Indemnifying Party is the Company Stockholders or the Participating Rights Holders, the Stockholder Representative Committee), of such Third-Party Claim and of its

claims of indemnification with respect thereto; provided, that failure to promptly give such notice will not relieve the Indemnifying Party of its indemnification obligations under this Section 9.3, except to the extent, if any, that the Indemnifying Party has actually been prejudiced thereby.

(b) Subject to paragraph (e) below, the Indemnifying Party will, upon its written confirmation of its obligation to indemnify the Indemnified Party in full with respect to such Third-Party Claim, have the right to assume the defense of the Third-Party Claim with counsel of its choice reasonably satisfactory to the Indemnified Party by written notice to the Indemnified Party within twenty (20) days after the Indemnifying Party has received notice of the Third-Party Claim; provided, however, that the Indemnifying Party must conduct the defense of the Third-Party Claim actively and diligently thereafter in order to preserve its rights in this regard; and provided, further, that the Indemnified Party may retain separate co-counsel at its sole cost and expense and participate in the defense of the Third-Party Claim. In addition, in the event that the Indemnifying Party assumes the defense of any Third-Party Claim in accordance with this paragraph (b), the limitations on recovery set forth in Section 9.5 below shall not apply to any Damages incurred by Parent in connection with such Third-Party Claim.

(c) The Indemnifying Party will not consent to the entry of any judgment or enter into any settlement with respect to the Third-Party Claim without the prior written consent of the Indemnified Party (which consent will not be unreasonably withheld or delayed) unless the judgment or proposed settlement (i) includes an unconditional release of all liability of each Indemnified Party with respect to such Third-Party Claim, (ii) involves only the payment of money damages that are fully covered by the Indemnifying Party (including amounts deemed to be paid by the Participating Rights Holders pursuant to Section 9.4 by distribution of amounts to Parent from escrow or by set-off from unpaid Contingent Payments to be made by Parent, to the extent that the amount of such payment is then determinable as a result of Worldwide Net Sales that have already been generated), and (iii) does not impose an injunction or other equitable relief upon the Indemnified Party. So long as the Indemnifying Party has assumed and is conducting the defense of the Third-Party Claim in accordance with Section 9.3(b) above, the Indemnified Party will not consent to the entry of any judgment or enter into any settlement with respect to the Third-Party Claim without the prior written consent of the Indemnifying Party (which consent will not be unreasonably conditioned, withheld or delayed by the Indemnifying Party).

(d) In the event that the Indemnifying Party fails to assume the defense of the Third-Party Claim in accordance with Section 9.3(b) above, (i) the Indemnified Party may defend against, and consent to the entry of any judgment or enter into any settlement with respect to, the Third-Party Claim in any manner it reasonably may deem appropriate (and the Indemnified Party need not consult with, or obtain any consent from, the Indemnifying Party in connection therewith) if either (x) the Indemnified Party is responsible for at least twenty-five (25%) of the Damages resulting from such Third-Party Claim or (y) such Third-Party Claim relates to the Intellectual Property of the Company, and (ii) the Indemnifying Party will remain responsible for any Damages the Indemnified Party may suffer as a result of such Third-Party Claim to the extent subject to indemnification under this Article 9.

(e) Notwithstanding the foregoing, Parent and the Surviving Corporation shall be responsible for the prosecution and defense of all Product Liability Claims and any claims relating to the Intellectual Property of the Company (collectively, the “Parent-Handled Claims”). Except to the extent that any such disclosure would cause a waiver of applicable attorney-client privilege, the Stockholder Representative Committee shall have the right to monitor the progress of the Parent Handled Claims, to review on a timely basis all pleadings and other filings relating thereto and to discuss with counsel to Parent and/or the Surviving Corporation such matters relating to the Parent-Handled Claims as may be reasonably appropriate. Parent and the Surviving Corporation shall pursue in good faith the prosecution or defense of all Parent-Handled Claims in a manner no less diligent than the conduct of the prosecution or defense of other claims against Parent analogous to such Parent-Handled Claim, through counsel of their selection, the prosecution or defense of all Parent-Handled Claims until such time, if any, that Parent shall elect not to pursue indemnification with respect to such Third-Party Claim. In the event that neither Parent nor the Surviving Corporation chooses to prosecute and defend any Parent-Handled Claim, notice of such shall be delivered promptly to the Stockholder Representative Committee and Stockholder Representative Committee shall be entitled to pursue the prosecution and defense of the Parent-Handled Claim, notice of which shall be delivered promptly to Parent, or the Surviving Corporation, provided, that the Stockholder Representative Committee shall not be entitled to enter into any voluntary settlement agreement of such Third-Party Claim without the express written consent of the Parent, which consent may not be unreasonably withheld, delayed or conditioned, and provided, further, that any such rights shall cease when the maximum aggregate liability described below in Section 9.5(b) has been reached.

(f) Parent shall, to the extent that Parent and the Surviving Corporation are entitled to indemnification for Damages pursuant to this Article 9 and it could reasonably be expected that Parent may recover a substantial portion of the Damages relating to such Parent-Handled Claim pursuant to this Article 9, (i) provide the Stockholder Representative Committee with access to appropriate employees of Parent and the Surviving Corporation for the purpose of discussing matters relating to Parent-Handled Claims as the Stockholder Representative Committee may from time to time reasonably request, and (ii) permit the Stockholder Representative Committee, upon its reasonable request, to participate in the process of any settlement or other resolution of any Parent-Handled Claims pursuant to this Article 9; provided, that Parent shall be entitled to settle, control, compromise or otherwise dispose of Parent-Handled Claims in its sole discretion and without obtaining the consent of the Indemnified Party, provided that it has actively and diligently pursued in good faith the prosecution or defense of such Parent-Handled Claim in a manner no less diligent than the conduct of the prosecution or defense of claims against Parent analogous to such Parent-Handled Claim.

Section 9.4 Payment of Claims. In the event of any bona fide claim for indemnification hereunder, the Indemnified Party will advise the Indemnifying Party that is required to provide indemnification therefor in writing. Such notice shall be signed by the Indemnified Party: (a) stating that such Indemnified Party has paid or incurred Damages, and (b) specifying in reasonable detail the individual items of Damages included in the amount so stated, the date each such item was paid or incurred, if applicable, and the nature of the misrepresentation, breach of warranty or covenant or other event or circumstances which resulted in the indemnification obligation of the Indemnifying Party. With respect to liquidated

claims for Damages, if within sixty (60) days the Indemnifying Party has not contested such claim in writing, the Indemnifying Party will be liable for the full amount thereof, subject to the limitations set forth in Section 9.5 and except as set forth in the following sentence of this Section 9.4, within ten (10) days after the expiration of such period. As the sole and exclusive remedy to satisfy any indemnification obligations of the Company Stockholders and the Participating Rights Holders pursuant to this Article 9 (other than in the case of fraud), and subject to all of the limitations of liability stated in this Article 9, Parent and the Surviving Corporation (and each of their respective directors, officers, employees, representatives and other Affiliates) shall have the right to recover Damages that have been incurred first from the Escrowed Funds to the extent available and then by setting off any remaining such amounts against any Contingent Payments that have not yet been paid and are otherwise due to the Participating Rights Holders pursuant to this Agreement or any indemnity payments owed by Parent and the Surviving Corporation pursuant to Section 9.1. All such recoveries from Escrowed Funds and offsets against Contingent Payments or indemnification payments shall be made on a pro rata basis from all Participating Rights Holders in the same proportions in which they would otherwise be entitled to receive such Escrowed Funds, Contingent Payments or indemnification payments. Any indemnification obligations of Parent or Merger Sub pursuant to this Article 9 shall be promptly paid, at Parent’s election (a) in cash, (b) by setting off against (i.e., reducing) any then existing indemnification obligations of the Participating Rights Holders due and payable to Parent under this Article 9, or (c) through a combination of the methods specified in clauses (a) and (b). The parties agree that to the greatest extent possible the payment of any indemnity hereunder shall be treated as an adjustment to the Merger Consideration paid by Parent hereunder for Tax purposes. Notwithstanding anything contained in this Agreement to the contrary, the amount of the Indemnifying Party’s liability under this Agreement shall be net of any insurance proceeds or other third party indemnity or contribution amounts actually recovered by an Indemnified Party. Pursuant to the definition of “Closing Payment Amount” in Section 10.2 hereof, Parent shall be entitled to reduce the Closing Payment by the amount of Damages incurred or to be incurred by Parent or the Company in respect of any Excess Parachute Claims, to the extent reasonably determinable prior to Closing.

Section 9.5 Limitations of Liability.

(a) Threshold. No Indemnifying Party will be required to indemnify an Indemnified Party hereunder with respect to any particular set of events, facts or circumstances (whether or not such events, facts or circumstances may represent a breach of more than one representation, warranty or covenant of a party) until such time as the aggregate amount of Damages for which (i) Parent, the Surviving Corporation, and their respective directors, officers, employees, representatives, and other Affiliates, on the one hand, or (ii) the Company, the Company Stockholders, the Participating Rights Holders and their respective directors, officers, employees, representatives, and other Affiliates, as the case may be, on the other hand, are otherwise entitled to indemnification pursuant to this Agreement with respect to such event, facts or circumstances exceeds $50,000, at which time the Indemnifying Party shall be obligated to indemnify the Indemnified Party for the full amount of such Damages subject to limitations of this Article 9. Notwithstanding anything to the contrary in this Section 9.5, the threshold limits imposed by this Section 9.5(a) shall not apply to any Damages arising out of or in connection with (A) any breach by the Company or any Participating Rights Holders of any Special

Representations, (B) any Special Claims, or (C) any intentional or willful breaches of this Agreement, or fraud or similar circumstances.

(b) Maximum Liability. The parties specifically agree that, notwithstanding any provision of this Agreement to the contrary, the maximum aggregate liability of all of the Company Stockholders and Participating Rights Holders for indemnification under this Article 9, except in the case of intentional or willful breach of this Agreement or fraud or similar circumstances, will not exceed a maximum amount equal to (x) the aggregate amount originally deposited into escrow pursuant to the Escrow Agreement, plus (y) $50,000,000. Notwithstanding anything to the contrary in this Agreement, except in the case of intentional or willful breaches of this Agreement or fraud by the Company or any Participating Rights Holder or similar circumstances, the liability of the Participating Rights Holders, including indemnification obligations, under this Agreement shall be limited to the Escrowed Funds and off-set against Contingent Payments in accordance with Section 9.4 (subject to the applicable Indemnity Limit stated herein), and once amounts held pursuant to the Escrow Agreement are released to the Participating Rights Holders or a Contingent Payment has been paid to the Participating Rights Holders, except in the case of intentional or willful breaches of this Agreement or fraud by the Company or any Participating Rights Holder or similar circumstances, Parent, the Surviving Corporation and any Affiliate thereof shall have no further claim to such amounts thereof from the Participating Rights Holders.

(c) Time Limit. All representations and warranties in this Agreement shall survive the Closing and shall expire on, and no Indemnifying Party will be liable for any Damages hereunder with respect to a breach of such representations and warranties unless a written claim for indemnification is given by the Indemnified Party to the Indemnifying Party with respect thereto prior to, the third anniversary of the Effective Time; provided, that the Special Representations shall survive, and written claims for indemnification based on such representations may be made, until the date on which the final Contingent Payment is made.

(d) Contribution. Any indemnification, contribution or other similar payment actually recovered by an Indemnified Party or its Affiliate from any third party with respect to any indemnity claim after it has received an indemnity payment hereunder shall be promptly paid over to the Indemnifying Party; provided, that the Indemnified Party shall not be obligated to pay over any such amount or benefit in excess of the amount paid by the Indemnifying Party to the Indemnified Party with respect to such claim.

(e) Insurance. Each Indemnified Party shall use reasonable efforts to collect any amounts available under insurance coverage for any Damages payable under Article 9, provided, that the Indemnified Party shall be permitted to pursue its other remedies with respect to such Damages simultaneously therewith. To the extent that the Indemnified Party actually receives any insurance proceeds in respect of any Damages which have already been paid to the Indemnified Party, the Indemnified Party shall reimburse the Indemnifying Party in an amount equal to the amount of such insurance proceeds actually received by the Indemnified Party (net of any deductible amounts) or, if less, the amount of such Damages for which the Indemnified Party has already been paid.

(f) Exclusive Remedy. From and after the Effective Time, except in the case of intentional or willful breach of this Agreement by the Company or any Participating Rights Holder, or fraud or similar circumstances, the indemnification provisions contained in Article 9 shall be the Buyer Indemnified Parties’ sole and exclusive remedy for any Damages incurred by the Buyer Indemnified Parties under this Agreement.

Section 9.6 Right to Bring Action; No Contribution. Notwithstanding anything in this Article 9 or elsewhere in this Agreement to the contrary, only the Stockholder Representative Committee shall have the right, power and authority to commence any action, suit or proceeding, including any arbitration proceeding, by and on behalf of any or all Participating Rights Holders or any other Indemnifying Party against Parent or the Surviving Corporation, or any other Indemnified Party, and in no event shall any Participating Rights Holder himself, herself or itself have the right to commence any action, suit or proceeding, including any arbitration proceeding, against Parent or the Surviving Corporation, or any other Indemnified Party. Each Participating Rights Holder waives, and acknowledges and agrees that he shall not have and shall not exercise or assert (or attempt to exercise or assert), any right of contribution, right of indemnity or other right or remedy against Surviving Corporation in connection with any indemnification obligation or any other liability to which he may become subject under or in connection with this Agreement.
