In the event of such Impending Generic Entry, in lieu of royalties on Net Sales of such Generic Equivalent which may become payable with respect to such country, Buyer and Seller shall share Gross Profits arising from the Commercialization of such Generic Equivalent in such country, with Buyer entitled to eighty percent (80%) and Seller entitled to twenty percent (20%) of such Gross Profits. For purposes hereof, “Impending Generic Entry” means that Launch of a Generic Equivalent for a Royalty Product or PTB Royalty Product in a country is likely to occur within three (3) months, as mutually determined by the Parties. In the event of any dispute with respect thereto, the matter will be resolved in accordance with Section 11.10.

          (iii) Payment. Buyer shall make the royalty payments to Seller and payments by Buyer to Seller with respect to sharing of Gross Profits described in Sections 2.8(d)(i)(A), (B) and (C) above on a quarterly basis not later than forty-five (45) days after the end of each calendar quarter (with payments made in respect of each of the first three (3) calendar quarters of each applicable calendar year constituting Buyer’s good faith estimate of the royalty (or share of Gross Profits) owed for such quarter, and with the payment made in respect of the fourth calendar quarter of such calendar year including a “true up” for the first three (3) calendar quarters’ payments, based on actual amounts owed by Buyer in respect of such three (3) calendar quarters relative to amounts paid by Buyer).

          (iv) Other Revenue; Pricing. Buyer agrees that it shall not, and shall cause its Affiliates not to, and, after the First Closing Date, Buyer shall cause all licensees, sublicensees, distributors or other agents to whom it or its Affiliates grant rights to Commercialize any Product (to the extent such rights include the right to promote and sell such Product) not to, distribute, bundle or otherwise sell such Product in any manner that would have the effect of reducing the Net Sales or Gross Profits arising from the Commercialization of such Product in favor of other revenue not subject to the royalties or sharing of Gross Profits set forth in Sections 2.8(d)(i)(A), (B) and (C); provided, that this clause (iv) will not apply to actions which have an unintended effect of causing such reduction.

          (v) Reports. In connection with any payments made pursuant to Sections 2.8(d)(i)(A), (B) and (C), Buyer shall simultaneously deliver to Seller a schedule setting forth in reasonable detail the calculation of Net Sales and Gross Profits and the amounts payable by it pursuant to each of the clauses of Sections 2.8(d)(i)(A), (B) and (C), in each case, on a Product-by-Product and country-by-country basis, and including deductions from gross sales to arrive at Net Sales.

          (vi) Books and Records; Audit Rights.

     (A) Each Party shall keep, and shall require its Affiliates to keep, complete, true and accurate books and records in accordance with GAAP (or other internationally recognized accounting standard in use by such Party) in relation to this Agreement, including Development Costs under Section 8.7 and, with respect to Buyer, in relation to Net Sales, Gross Profits and royalties. Each Party will keep such books and records at its principal place of business (or the place of business of its Subsidiaries) for at least three (3) years following the calendar quarter to which they pertain. After the First Closing Date, Buyer shall ensure that any licensees, sublicensees, distributors or other agents to whom it or its Affiliates grant rights to Commercialize any Product (to the extent such rights include the right to promote and sell such Product) to be bound by similar record keeping obligations in relation to Net Sales, Gross Profits and royalties.

     (B) Each Party (the “Audit Rights Holder”) may, upon written request and at its expense (except as provided for in Section 2.8(d)(vi)(F)), cause an internationally-recognized independent accounting firm selected by it (except one that serves as such Party’s independent auditors or to whom the auditee otherwise has a reasonable objection) (the “Audit Team”) to audit during ordinary business hours the books and records of the other Party (“Auditee”) and its Affiliates (and with respect to Buyer, its licensees, sublicensees, distributors or other agents) for a given calendar year and the correctness of any payments made or required to be made to or by such Party during such calendar year, and any report, data or calculation underlying such payment (or lack thereof), pursuant to the terms of this Agreement.

     (C) In respect of each audit of the Auditee’s books and records: (i) the Auditee shall be audited not more frequently than once per year; and (ii) the Audit Rights Holder shall only be entitled to audit books and records of an Auditee from the three (3) calendar years prior to the calendar year in which the audit request is made.

     (D) In order to initiate an audit for a particular calendar year, the Audit Rights Holder must provide written notice to the Auditee, which notice shall include one or more proposed dates for the audit and which notice shall be given not less than forty-five (45) days prior to the first proposed audit date. The Auditee will reasonably accommodate the scheduling of such audit. The Auditee shall provide the Audit Team(s) with full and complete access to the applicable books and records relating to the Products and otherwise reasonably cooperate with such audit.

     (E) The audit report and basis for any determination by an Audit Team shall be made available for review and comment by the Auditee, and the Auditee shall have the right, at its expense, to request a further determination by such Audit Team as to matters which the Auditee disputes (to be completed no more than thirty (30) days after the applicable audit report is provided to such Auditee and to be limited to the disputed matters). If the Parties disagree as to such further determination, the Audit Rights Holder and the Auditee shall mutually select an internationally-recognized independent accounting firm that shall make a final determination as to the remaining matters in dispute, which determination shall be binding upon the Parties.

     (F) If any audit finds any under-reporting or underpayment, or overcharging by any Party, the underpaying or overcharging Party shall remit such underpayment or reimburse such overcharge to the other Party within fifteen (15) days of receiving the final audit report establishing such obligation. Further, if the audit for any one or more calendar years shows an under-reporting or underpayment or an overcharge by the Auditee for that period in excess of five percent (5%) of the amounts properly determined, the Auditee shall reimburse the Audit Rights Holder for its out-of-pocket expenses, including the fees and expenses paid by it to the Audit Team(s), in connection with said audit, which reimbursement shall be made within thirty (30) days of receiving appropriate invoices and other support for such audit-related costs.

     (G) After the First Closing Date, Buyer shall ensure that any licensees, sublicensees, distributors or other agents to whom it or its Affiliates grant rights to Commercialize any Product (to the extent such rights include the right to promote and sell such Product), to be bound by similar audit provisions.

          (vii) Foreign Exchange. The royalties and payments by Buyer with respect to sharing of Gross Profits received by this Section 2.8 will be payable in U.S. dollars. For the purpose of computing the Net Sales of or Gross Profits arising from the Commercialization of Products sold in a currency other than U.S. dollars, such currency shall be converted from the local currency to U.S. dollars by Buyer using the relevant exchange rate, as reported by the Wall Street Journal, in effect on the last Business Day of the relevant calendar quarter in which such sales were made (or such Gross Profits were realized).

          (e) License or Assignment of Rights. Notwithstanding anything to the contrary in this Agreement, Buyer shall not sell, assign, transfer, dispose of or convey any of the Purchased Assets or rights in any Products to any other Person unless such Person has agreed to be bound by the terms and conditions of this Section 2.8; provided, however, that Buyer shall and hereby does guarantee the payment by such Person of amounts payable to Seller pursuant to this Section 2.8.

          (f) Interest. If a Party fails to pay in full on or before the date due any payment that is required to be paid under this Agreement, such Party will also pay to the other Party, on demand, interest on any such amount beginning on such due date at an annual rate (calculated on the basis of a 360-day year) equal to the “base rate” as announced by JPMorgan N.A., or any successor thereto, in New York, New York in effect on such due date, plus two percent (2%) to be assessed from the date payment of the amount in question first became due.

          (g) Set Off. The Post-Closing Payments (if any) payable pursuant to this Section 2.8 shall be subject to reduction for (i) claims for indemnification made by Buyer pursuant to Article X, which are finally determined pursuant to Section 10.6 to be due and owing to Buyer and (ii) breach of Seller’s obligation to use the cash in the Development Bank Account exclusively for Development Costs during the Seller Expense Period as required by Section 8.7(c).

          2.9 Purchase Price Allocation. Seller and Buyer agree that the Purchase Price shall be allocated among the Purchased Assets and the Shares, and the portion of the Purchase Price allocated to the Purchased Assets shall be allocated among the Purchased Assets in accordance with Section 1060 of the Code, pursuant to an allocation schedule (the “Allocation Schedule”) as agreed by Buyer and Seller in accordance with this Section 2.9. Buyer shall provide to Seller the Allocation Schedule within ninety (90) days after the First Closing Date. Thereafter, Seller shall have thirty (30) days either to (a) agree with and accept the Allocation Schedule or (b) in good faith suggest changes to the Allocation Schedule and attempt to agree with Buyer as to the contents of the Allocation Schedule. Seller and Buyer shall provide each other promptly with any other information required to complete the Allocation Schedule. If Seller and Buyer agree on the Allocation Schedule within one hundred and thirty-five (135) days following the First Closing Date, Seller and Buyer shall file IRS Form 8594 and any required attachments thereto (“Form 8594”), together with all federal, state and local Tax Returns, in a manner consistent with and in accordance with the Allocation Schedule. In addition, Seller and Buyer hereby undertake and agree to timely file any information that may be required to be filed pursuant to the U.S. Treasury Regulations promulgated under Section 1060(b) of the Code in a manner consistent with and in accordance with the Allocation Schedule. In any proceeding

related to the determination of any Tax, neither Buyer nor Seller shall contend or represent that the Allocation Schedule is not a correct allocation of the Purchase Price. If Seller and Buyer are unable to reach an agreement within one hundred and thirty-five (135) days following the First Closing Date, Seller and Buyer shall, within fifteen (15) days after the expiration of such one hundred and thirty-five (135) day period, at their joint expense, engage the Independent Accounting Firm to determine the appropriate Allocation Schedule, and they shall use their commercially reasonable efforts to cause the Independent Accounting Firm to determine the Allocation Schedule in a manner that is reasonable and in accordance with Section 1060 of the Code and the Treasury Regulations promulgated thereunder, within thirty (30) days after it is retained for such purpose. The determination of the Allocation Schedule by the Independent Accounting Firm shall be binding on Seller and Buyer. Not later than thirty (30) days prior to filing its respective Form 8594 relating to this transaction, Seller and Buyer shall each deliver to the other party a copy of its Form 8594, and within ten (10) days after filing its Form 8594 with the IRS pursuant to this Section 2.9, each Party shall provide the other with a copy of such form as filed. To the extent required by applicable Law, the Allocation will be revised to reflect any adjustment of the Purchase Price pursuant to this Agreement.

          2.10 Withholding. Buyer shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to Seller such amounts as Buyer is required to deduct and withhold under the Code, or any Tax law, with respect to the making of such payment. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of whom such deduction and withholding was made.

          (a) From the Execution Date until the First Closing Date or, if earlier, the termination of this Agreement pursuant to Article IX, Seller shall not, and shall cause its Subsidiaries not to, and shall use commercially reasonable efforts to cause its Representatives not to, directly or indirectly: (i) solicit, initiate or knowingly or intentionally facilitate any inquiry with respect to, or the making, submission or announcement of, any Acquisition Proposal or any proposal that would reasonably be expected to lead to any Acquisition Proposal, (ii) furnish to any Person any non-public information relating to Seller or any of its Subsidiaries in connection with an Acquisition Proposal (except to the extent specifically permitted pursuant to Section 6.5(b)), (iii) participate or engage in discussions or negotiations with any Person with respect to any Acquisition Proposal, except to notify such Person as to the existence of the provisions of this Agreement or to the extent specifically permitted pursuant to Section 6.5(b), (iv) approve, endorse or recommend any Acquisition Proposal (except to the extent specifically permitted pursuant to Section 6.5(d)), or (v) enter into any letter of intent or similar document or any agreement, commitment or understanding contemplating or otherwise relating to any Acquisition Proposal or a transaction contemplated thereby (except for confidentiality agreements specifically permitted pursuant to Section 6.5(b)). Without limiting the foregoing, it is agreed that any violation of the restrictions set forth in the preceding sentence by any Representative of Seller or any Subsidiary of Seller shall be a breach of this Section 6.5(a) by Seller. On the Execution Date, subject to Section 6.5(b) Seller shall, and shall cause each of its Subsidiaries to, immediately cease and use commercially reasonable efforts to cause its Representatives to terminate any solicitation, discussion or negotiation with any Persons conducted by Seller or its Subsidiaries or any of their Representatives prior to the Execution Date with respect to any Acquisition Proposal.

          (b) Notwithstanding anything to the contrary contained in Section 6.5(a), if at any time following the Execution Date and prior to the earlier of obtaining the Required Seller Stockholder Vote and the termination of this Agreement pursuant to Article IX (i) Seller has fully complied with its obligations in Section 6.5(a) and has received an Acquisition Proposal from any Person or “group” (as determined under Section 13(d)(3) of the Exchange Act) that the board of directors of Seller believes in good faith to be bona fide, and (ii) the board of directors of Seller determines in good faith, after consultation with its financial advisors and outside counsel, that such Acquisition Proposal constitutes or may reasonably be expected to result in a Superior Proposal, then Seller may (A) furnish information (including non-public information) with respect to Seller and its Subsidiaries to the Person or group making such Acquisition Proposal and (B) participate in discussions or negotiations with the Person or group making such Acquisition Proposal regarding such Acquisition Proposal; provided, that Seller (x) will not, and will not allow its Subsidiaries to (and will use commercially reasonable efforts to cause its Representatives not to), disclose any non-public information to such Person or group without first entering or having entered into a confidentiality agreement with such Person or group that is at least as restrictive on such Person or group as the Confidentiality Agreement is on Buyer and (y) will promptly provide to Buyer any material non-public information concerning Seller or its

Subsidiaries provided by Seller to such other Person or group which was not previously made available to Buyer, except to the extent restricted by applicable Laws.

          (c) From and after the Execution Date, Seller shall promptly (within 48 hours of, or the next Business Day immediately following, if later) notify Buyer in the event that any of Seller, its Subsidiaries or its Representatives receives any Acquisition Proposal or written indication by any Person or group that it is considering making an Acquisition Proposal and shall disclose to Buyer the identity of the other Person making such Acquisition Proposal. Seller shall keep Buyer informed (orally and in writing) on a current basis of the occurrence of any material changes or developments of the status of any such Acquisition Proposal or written indication (including the material terms and conditions thereof and of any material modification thereto), and any material developments related thereto.

          (d) Notwithstanding anything to the contrary contained in Section 6.5(a), the board of directors of Seller may, at any time prior to obtaining the Required Seller Stockholder Vote, withdraw, modify or qualify, or propose publicly to withdraw, modify or qualify, in a manner adverse to Buyer, the Seller Board Recommendation and/or endorse or recommend to Seller’s stockholders any Superior Proposal (a “Change of Board Recommendation”) if, but only if, (A) the board of directors of Seller concludes in good faith, after consultation with outside counsel, that failure to take such action would be inconsistent with its fiduciary obligations under applicable Law and (B) in the case of any Superior Proposal, Seller has given Buyer five (5) Business Days prior written notice that the board of directors intends to make a Change of Board Recommendation (the “Superior Proposal Notice”) and for a period of not less than five (5) Business Days after Buyer’s receipt of such Superior Proposal Notice, Seller shall, if requested by Buyer, negotiate in good faith with Buyer to revise this Agreement so that the Acquisition Proposal that constituted a Superior Proposal no longer constitutes a Superior Proposal (a “Former Superior Proposal”). The terms and conditions of this Section 6.5 shall again apply to any inquiry or proposal made by any Person who withdraws a Superior Proposal or who made a Former Superior Proposal (after withdrawal or after such time as their proposal is a Former Superior Proposal). Seller may, if it receives an Acquisition Proposal, delay the mailing of the Proxy Statement and/or the holding of the Seller Stockholders’ Meeting, in each case to provide a reasonable opportunity for the board of directors of Seller to consider such Acquisition Proposal and to determine the effect of the same, if any, on the Seller Board Recommendation. Except as permitted by this Section 6.5, the Proxy Statement shall include the Seller Board Recommendation.

          (e) Nothing contained in this Agreement shall prohibit the board of directors of Seller from disclosing the fact that the board of directors of Seller has received an Acquisition Proposal and the terms of such Acquisition Proposal, if the board of directors of Seller determines, after consultation with its outside legal counsel, that (i) failure to make such disclosure would be inconsistent with its fiduciary duties under applicable Law or (ii) Seller is otherwise required to make such disclosure.

          (f) For purposes of this Agreement, (i) “Acquisition Proposal” means any inquiry, offer or proposal, or any indication of interest in making an offer or proposal, made by a Person or group at any time which is structured to permit such Person or group to acquire beneficial ownership of any Purchased Assets or at least twenty-five percent (25%) of the assets

of, or equity interest in, Seller and its Subsidiaries, taken as a whole, pursuant to a merger, consolidation or other business combination, sale of shares of capital stock, sale of assets, tender offer or exchange offer or similar transaction, in each case other than the Transactions, and (ii) “Superior Proposal” means any bona fide Acquisition Proposal made by a Person or group (except that references in the definition thereof to “at least twenty-five percent (25%) of the assets of, or equity interest in, Seller and its Subsidiaries, taken as a whole,” shall be replaced by “more than fifty percent (50%) of the assets of, or equity interests in, Seller and its Subsidiaries, taken as a whole”), in each case other than the Transactions, made in writing that the board of directors of Seller has determined in its good faith judgment (after consultation with its financial advisors and outside counsel and after taking into account all legal, financial, regulatory and other aspects of the proposal, including the financing terms thereof) is more favorable to Seller and/or Seller’s stockholders than the Transactions. Notwithstanding anything to the contrary contained herein, in no event shall any acquisition by any Person or group from Seller at any time after the termination of this Agreement of any equity “securities” (as defined in Section 2(a)(1) of the Securities Act) of Seller constitute an Acquisition Proposal or a Superior Proposal if the board of directors of Seller shall in good faith determine that such acquisition is made in connection with a bona fide financing or capital raising arrangement (an “Equity Financing”), nor shall any agreement entered into by any Person or group with Seller after the termination of this Agreement in connection with or relating to an Equity Financing constitute an Acquisition Proposal or a Superior Proposal.

          (g) Notwithstanding anything to the contrary contained in this Agreement, the obligation of Seller to call, give notice of, convene and hold the Seller Stockholders’ Meeting and to hold a vote of Seller’s stockholders on the asset sale contemplated by this Agreement and the Charter Amendment shall not be limited or otherwise affected by the commencement, disclosure, announcement or submission to it of any Acquisition Proposal (whether or not a Superior Proposal), or by any Change of Board Recommendation. Seller agrees that it shall not submit to the vote of its stockholders any Acquisition Proposal (whether or not a Superior Proposal) or propose to do so.

efforts to provide Buyer with the financial statements and other information and documents pertaining to the Business that Buyer will be required by applicable rules and regulations of the SEC to include in its filings and (ii) use commercially reasonable efforts to cause the independent auditors for Seller to promptly deliver such information and provide access to files and work papers in connection therewith as Buyer may reasonably request.

A notice contemplated by clause (i) (other than a MAE Notice) or clause (ii) of the first sentence of this paragraph (b) shall not be deemed to update the Schedules included in the Seller Disclosure Letter or adversely affect Buyer’s rights under this Agreement, including for the purposes of Buyer’s rights under Articles VII, IX and X of this Agreement.

          (g) Seller and Buyer each agree to promptly prepare and file whatever filings, requests or applications are required or deemed advisable to be filed with any Regulatory Authority in connection with the Transactions and transfer and assumption of the Regulatory Approvals and to cooperate with one another as reasonably necessary to accomplish the foregoing.

The Parties agree to use their commercially reasonable efforts to resolve any disagreements over such Tax Return as promptly as possible.

The Filing Party shall provide the non-Filing Party with evidence reasonably satisfactory to the non-Filing Party that such Transfer Taxes have been paid by the Filing Party.

          (b) Buyer and Seller agree to furnish or cause to be furnished to the other, upon request, as promptly as practicable, such information and assistance relating to the Purchased Assets, including, without limitation, access to books and records, as is reasonably necessary for the filing of all Tax Returns by Buyer or Seller, the making of any election relating to Taxes, the preparation for any audit by any taxing authority and the prosecution or defense of any claim, suit or proceeding relating to any Tax. Each of Buyer and Seller shall retain all books and records with respect to Taxes pertaining to the Purchased Assets for a period of at least seven (7) years following the applicable Closing Date.

          (c) Seller shall be responsible for and shall promptly pay when due (x) all Property Taxes levied with respect to the First Closing Date Purchased Assets attributable to the Pre-Closing Tax Period and (y) all Property Taxes levied with respect to the Second Closing Date Purchased Assets attributable to the Second Pre-Closing Tax Period, and Buyer shall be responsible for and shall promptly pay when due (x) all Property Taxes levied with respect to the First Closing Date Purchased Assets attributable to the Post-Closing Tax Period and (y) all Property Taxes levied with respect to the Second Closing Date Purchased Assets attributable to the Second Post-Closing Tax Period.

Seller shall be liable for the proportionate amount of such Property Taxes that is attributable to the relevant Pre-Closing Tax Period, and Buyer shall be liable for the proportionate amount of such Property Taxes that is attributable to the relevant Post-Closing Tax Period. Upon receipt of any bill for such Property Taxes, Buyer or Seller, as applicable, shall present a statement to the other setting forth the amount of reimbursement to which each is entitled under this Section 8.6(c) together with such supporting evidence as is reasonably necessary to calculate the proration amount. The proration amount shall be paid by the party owing it to the other within ten (10) days after delivery of such statement. In the event that Buyer or Seller makes any payment for which it is entitled to reimbursement under this Section 8.6(c), the applicable party shall make such reimbursement promptly but in no event later than ten (10) days after the presentation of a statement setting forth the amount of reimbursement to which the presenting party is entitled along with such supporting evidence as is reasonably necessary to calculate the amount of reimbursement.

          (d) Seller shall promptly notify Buyer in writing upon receipt by Seller of notice of any pending or threatened Tax audits or assessments relating to the income, properties or operations of Seller that reasonably may be expected to relate to or give rise to an Encumbrance on the Purchased Assets.

To the extent there arise any inquiries, claims, assessments, audits or similar events with respect to Taxes relating to the Purchased Assets for a Pre-Closing Tax Period (any such inquiry, claim, assessment, audit or similar event, a “Tax Matter”) and Seller acknowledges in writing to Buyer that Seller shall be obligated to pay in full any Liability that results from a Tax Matter under the terms of its indemnity under this Agreement (a “Complete Indemnity Obligation”), then Seller shall be entitled, if it so elects at its own cost, risk and expense, by written notice to Buyer within ten (10) Business Days of the institution thereof, to take sole control of the conduct of such Tax Matter, including any settlement or compromise thereof, provided, however, that Seller shall keep Buyer reasonably informed of the progress of any such Tax Matter and shall not effect any such settlement or compromise of such Tax Matter which would result in a material adverse Tax consequence to Buyer without obtaining Buyer’s prior written consent thereto, which shall not be unreasonably withheld or delayed; and,

provided, further, that to the extent Seller would not have a Complete Indemnity Obligation to Buyer hereunder in respect of any Tax Matter, Seller and Buyer shall each be entitled to exercise joint control of the conduct of such Tax Matter with the other Party, with each bearing its own costs and expenses. In the event of any conflict or overlap between the provisions of this Section 8.6(e) and Section 10.6 (relating to indemnification procedures), the provisions of this Section 8.6(e) shall control.

          (f) Seller and Buyer hereby waive compliance with any “bulk sales” Laws (including Laws relating to obtaining Tax clearance certificates and any requirement to withhold any amount from payment of the Purchase Price or Post-Closing Payments) applicable to the sale to Buyer of the Purchased Assets by Seller.

          8.11 Covenant Not to Compete.

          (a) Seller understands that Buyer shall be entitled to protect and preserve the value of the Business following the First Closing Date to the extent permitted by Law and that Buyer would not have entered into this Agreement absent the provisions of this Section 8.11. During the Joint Development Period and for a period of two (2) years thereafter (the “Non-Compete Period”), Seller and its Subsidiaries, and any successor to all or substantially all of their assets, taken as a whole, shall not, directly or indirectly (1) engage in the manufacture, Development or Commercialization in the Territory (A) of Products containing Progesterone, or (B) any other products which are approved or being Developed for any pre-term birth indication ((i) and (ii), collectively, “Competing Activities”); or (2) engage in, own, manage, operate, advise, control or in any way participate in the ownership, management, operation, financing or control of any business engaged in Competing Activities (a “Competing Business”). The restrictions set forth in this Section 8.11 shall not be construed to preclude, prohibit or restrict (i) Seller, from performing its obligations under this Agreement or the Other Agreements; (ii) any investment by Seller or its Subsidiaries in any class of publicly traded debt or equity securities of any Competing Business so long as Seller does not hold at any time during such period more than five percent (5%) of such class of issued and outstanding voting securities of such publicly traded company, and so long as Seller does not otherwise exercise any management or control with respect to such Competing Business; or (iii) any activity set forth on Schedule 8.11.

          (b) If a court determines that the foregoing restrictions are too broad or otherwise unreasonable under applicable Law, including with respect to time or scope, the court is hereby requested and authorized by the Parties to revise the foregoing restriction to include the

maximum restrictions allowable under applicable Law. Each of the Parties acknowledges, however, that this Section 8.11 has been negotiated by the Parties and that the Territory and Non-Compete Period are reasonable in light of the circumstances pertaining to the Parties.

          (c) Notwithstanding any other provision of this Agreement, it is understood and agreed that the remedy of indemnity payments pursuant to Article X and other remedies at law, if any, would be inadequate in the case of any breach of the covenants contained in this Section 8.11, and, accordingly, Buyer shall be entitled to equitable relief, including the remedy of specific performance, with respect to any breach or attempted breach of such covenants.

          (iii) if, prior to obtaining the Required Seller Stockholders Vote a Change of Board Recommendation shall have occurred; provided, that any such termination must occur within five (5) Business Days following the occurrence of any Change of Board Recommendation.

          9.2 Procedure and Effect of Termination.

          (a) Upon termination of this Agreement by Seller or Buyer pursuant to Section 9.1, this Agreement shall terminate forthwith and become void and there shall be no Liability or obligation on the part of the Parties or their respective Representatives, except as provided in this Section 9.2. Termination of this Agreement shall terminate all outstanding obligations and liabilities between the Parties arising from this Agreement except those set forth in: (i) Section 8.1(a), this Article IX and Article XI; (ii) the Confidentiality Agreement; and (iii) any other provisions of this Agreement that specifically state that they shall survive termination of this Agreement.

          (b) In the event that this Agreement is terminated pursuant to Section 9.1(c)(iii), then Seller shall pay to Buyer a fee of two million dollars ($2,000,000) (the “Termination Fee”) within two (2) Business Days after such termination.

          (c) In the event that an Acquisition Proposal has been publicly announced and, thereafter, (x) this Agreement is terminated pursuant to Section 9.1(a)(ii) or Section 9.1(a)(iii) and (y) within twelve (12) months after the termination of this Agreement, Seller shall have entered into an agreement regarding or consummated a transaction which would have constituted an Acquisition Proposal (excluding an Equity Financing and/or any agreement relating thereto), then Seller shall pay to Buyer, the Termination Fee upon the earlier of (i) two

(2) days following entering into any such agreement or (ii) immediately upon the consummation of any such transaction.

          (d) The Termination Fee shall be the sole and exclusive remedy of Buyer under circumstances where the Termination Fee is payable by Seller and upon payment of the Termination Fee in accordance with this Section 9.2, Seller shall not have any further Liability or obligation relating to or arising out of this Agreement; provided, however, that nothing in this Agreement shall limit the ability of either Party to obtain specific performance of this Agreement or to recover damages (including damages in excess of the Termination Fee) in the event of fraud or a willful breach of this Agreement by the other Party.

          (e) Each of the Parties acknowledges that the agreements contained in this Section 9.2 are an integral part of the Transactions contemplated by this Agreement and that without these agreements, Buyer would not enter into this Agreement. Accordingly, if Seller fails promptly to pay an amount due pursuant to this Section 9.2, and, in order to obtain such payment, Buyer commences a suit that results in a judgment against Seller, Seller shall pay to Buyer its reasonable costs and expenses (including attorneys’ fees and expenses) in connection with such suit, together with interest on the amount due from the date such payment was required to be made until the date of payment at the prime rate of Citibank, N.A. in effect on the date such payment was required to be made.

ARTICLE X.
INDEMNIFICATION

          10.1 Survival of Representations.

          (a) The representations and warranties and the covenants, agreements and obligations to be performed on or prior to the First Closing Date (the “Pre-Closing Covenants”) contained in this Agreement shall survive the First Closing Date solely for purposes of this Article X and shall terminate and no longer survive at the close of business on the eighteenth (18^th) month anniversary of the First Closing Date (the “Basic Survival Period”); provided, however, that the representations and warranties of Seller in Sections 4.2, 4.4 and 4.5 and of the Buyer in Sections 5.2 and 5.3 (collectively, the “Fundamental Representations”) and the representations and warranties of Seller in Section 4.9 shall survive the First Closing Date until the expiration of the applicable statute of limitations (with extensions) with respect to the matters addressed in such sections. The period of time a representation, warranty or the Pre-Closing Covenants survives the First Closing Date pursuant to the preceding sentence shall be the “Survival Period” with respect to such representation, warranty or the Pre-Closing Covenants. Subject to Section 10.6, so long as a Party gives written notice of an indemnification claim notice, including a description of the claim and the amount of claimed Losses for such claim on or before the expiration of the applicable Survival Period, such Indemnified Party shall be entitled to pursue its rights to indemnification under Section 10.2 or 10.3, as applicable. Subject to Section 10.6, in the event notice of any claim(s) for indemnification under Section 10.2 or 10.3 shall have been given within the applicable Survival Period and such claim(s) have not been finally resolved by the expiration of such Survival Period, the representations, warranties or Pre-Closing Covenants, as applicable, that are the subject of such claim(s) shall survive the end of

the Survival Period of such representations, warranties or Pre-Closing Covenants until such claim(s) are finally resolved, but such representations, warranties and Pre-Closing Covenants shall only survive with respect to such asserted claim(s).

          (b) The covenants and agreements contained in this Agreement that require by their terms performance or compliance on and after the First Closing Date shall continue in force thereafter in accordance with their terms or if no term is specified, indefinitely.

          10.2 Indemnification by Seller. Subject to the limitations and terms of this Article X and Section 6.9(b), on and after the First Closing Date, Seller shall indemnify, reimburse and defend Buyer and its Affiliates and each of their respective Representatives, successors and assigns (“Buyer Indemnitees”) from and against, and hold them harmless from, any Losses incurred (payable promptly upon written request), without duplication, to the extent arising from, in connection with, or otherwise with respect to:

          (a) subject to Section 10.1, any breach of any representation or warranty of Seller contained in this Agreement;

          (b) any breach of any representation and warranty of Seller under any Other Agreement or any covenant, agreement or obligation of Seller contained in this Agreement or in any Other Agreement;

          (c) any Excluded Liability; and

          (d) any fees, expenses or other payments incurred or owed by Seller to any brokers, financial advisors or other comparable Persons retained or employed by Seller in connection with the Transactions.

          10.3 Indemnification by Buyer. Subject to the limitations and terms of this Article X, on and after the First Closing Date, Buyer shall indemnify and defend Seller, its Affiliates and each of their respective Representatives, successor and assigns (“Seller Indemnitees”) from and against, and agrees to hold them harmless from, any Losses, as incurred (payable promptly upon written request), without duplication, to the extent arising from, in connection with, or otherwise with respect to:

          (a) subject to Section 10.1, any breach of any representation or warranty of Buyer contained in this Agreement;

          (b) any breach of any representation or warranty of Buyer under any Other Agreement or any covenant, agreement or obligation of Buyer contained in this Agreement or in any Other Agreement;

          (c) any Assumed Liability;

          (d) any fees, expenses or other payments incurred or owed by Buyer to any brokers, financial advisors or other comparable Persons retained or employed by Buyer in connection with the Transactions; and

          (e) any Losses of Seller arising out of or resulting from the circumstances described in Schedule 10.3(e).

          10.4 Limitation on Losses; Calculation of Losses; Treatment of Indemnification Payments.

          (a) Seller and Buyer shall have no indemnification obligations pursuant to Section 10.2(a) and Section 10.3(a) as applicable, except to the extent that the aggregate amount of Losses incurred or suffered by Indemnified Parties, that Buyer or Seller, as applicable, is otherwise responsible for under Section 10.2(a) or Section 10.3(a) as applicable, exceeds five hundred thousand dollars ($500,000) (the “Deductible”), at which time an Indemnified Party shall be entitled to assert claims against Buyer or Seller, as applicable, for all Losses in excess of, but excluding the Deductible; provided, that, subject to the immediately following proviso, the maximum liability of Buyer and Seller for all claims by Indemnified Parties under Section 10.2(a) or Section 10.3(a) as applicable, shall not in any case exceed seven million five hundred thousand dollars ($7,500,000) (the “Liability Cap”); provided further, that for purposes of claims made by Buyer Indemnitees pursuant to Sections 10.2(a) or Seller Indemnitees pursuant to Section 10.3(a) arising from the breach of a Fundamental Representation or fraud or intentional misrepresentation by Buyer or Seller, as applicable, the Liability Cap shall be inapplicable.

          (b) The amount of any Loss for which indemnification is provided under Section 10.2 or Section 10.3 shall be reduced to take account of any Tax benefit actually realized by the Indemnified Party arising from the incurrence or payment of any such Loss in the Tax year of such incurrence or payment, or in the subsequent two (2) Tax years. In computing the amount of any such Tax benefit, the Indemnified Party shall be deemed to recognize all other items of income, gain, loss deduction or credit before recognizing any item arising from the receipt of any indemnity payment under Section 10.2 or Section 10.3 or the incurrence or payment of any indemnified Loss.

          (c) The amount of Losses recoverable by an Indemnified Party under Section 10.2 or Section 10.3 shall be reduced by the amount of any payment received under insurance policies or from any third-party indemnitor by such Indemnified Party (or an Affiliate thereof) with respect to the Losses to which such claim for indemnification relates, less the reasonable cost incurred in obtaining such payment. If an Indemnified Party (or an Affiliate) receives any insurance or other payment in connection with any claim for Losses for which it has already received an indemnification payment from the Indemnifying Party, it shall pay to the Indemnifying Party, within thirty (30) days of receiving such payment, the amount of such payment (less the reasonable cost incurred in obtaining such payment) not to exceed the amount previously received by the Indemnified Party under Section 10.2 or Section 10.3, as applicable, with respect to such claim from the Indemnifying Party.

          (d) Any indemnity payment under Section 10.2 or Section 10.3 shall be treated as an adjustment to the Purchase Price, including for Tax purposes, to the maximum extent allowable under applicable Law.

          (e) Notwithstanding anything to the contrary herein, Seller shall not in any event be liable to the Buyer Indemnitees and Buyer shall not in any event be liable to the Seller

Indemnitees on account of any indemnity obligation set forth in Section 10.2 or Section 10.3, respectively, for any indirect, consequential or punitive damages (including, but not limited to, lost profits, loss of use, damage to goodwill or loss of business).

          10.5 No Termination of Indemnification. Except with respect to the Pre-Closing Covenants, the obligations to indemnify and hold harmless any Party pursuant to Sections 10.2(b)-(d) and Section 10.3(b)-(e), shall not terminate.

          10.6 Procedures.

          (a) In order for a party (the “Indemnified Party”) to be entitled to any indemnification provided for under this Agreement in respect of, arising out of or involving a claim made by any Person against the Indemnified Party (a “Third-Party Claim”), such Indemnified Party must notify the indemnifying party (the “Indemnifying Party”) in writing (and in reasonable detail) of the Third-Party Claim within fifteen (15) Business Days after receipt by such Indemnified Party of notice of the Third-Party Claim; provided, however, that failure to give such notification shall not affect the indemnification provided hereunder except to the extent the Indemnifying Party shall have been actually prejudiced as a result of such failure. Thereafter, the Indemnified Party shall deliver to the Indemnifying Party, within five (5) Business Days after the Indemnified Party’s receipt thereof, copies of all notices and documents (including court papers) received by the Indemnified Party relating to the Third-Party Claim.

          (b) If a Third-Party Claim is made against an Indemnified Party, the Indemnifying Party shall be entitled to participate in the defense thereof and, if it so chooses, to assume the defense thereof with counsel selected by the Indemnifying Party. Should the Indemnifying Party so elect to assume the defense of a Third-Party Claim, the Indemnifying Party shall not be liable to the Indemnified Party for any legal expenses subsequently incurred by the Indemnified Party in connection with the defense thereof unless (i) a conflict of interest arises between the Indemnifying Party and the Indemnified Party such that legal counsel cannot represent both the Indemnifying Party and the Indemnified Party or (ii) the Indemnified Party is advised in writing by counsel that one or more legal defenses is available to it that are different from those of the Indemnifying Party. If the Indemnifying Party assumes such defense, the Indemnified Party shall have the right to participate in the defense thereof and to employ counsel, at its own expense (except under the conditions described in the prior sentence), separate from the counsel employed by the Indemnifying Party, it being understood that the Indemnifying Party shall control such defense. The Indemnifying Party shall be liable for the fees and expenses of counsel employed by the Indemnified Party for any period during which the Indemnifying Party has not assumed the defense thereof (other than during any period in which the Indemnified Party shall have failed to give notice of the Third-Party Claim as provided above). If the Indemnifying Party chooses to defend or prosecute a Third-Party Claim, all the Indemnified Parties shall cooperate in the defense or prosecution thereof. Such cooperation shall include the retention and (upon the Indemnifying Party’s request) the provision to the Indemnifying Party of records and information that are reasonably relevant to such Third-Party Claim, and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Whether or not the Indemnifying Party assumes the defense of a Third-Party Claim, the Indemnified Party shall not admit any liability with respect to, or settle, compromise or discharge, such Third-Party Claim

without the Indemnifying Party’s prior written consent (which consent shall not be unreasonably withheld). The Indemnifying Party may not settle, compromise or discharge any Third-Party Claim without the Indemnified Party’s prior written consent (which shall not be unreasonably withheld), unless such settlement, compromise or discharge shall obligate the Indemnifying Party to pay the full amount of the Liability in connection with such Third-Party Claim, releases the Indemnified Party completely in connection with such Third-Party Claim and does not materially adversely affect the Indemnified Party.

          (c) In the event any Indemnified Party should have a claim against any Indemnifying Party under Section 10.2 or Section 10.3 that does not involve a Third-Party Claim being asserted against or sought to be collected from such Indemnified Party, the Indemnified Party shall deliver notice of such claim with reasonable promptness to the Indemnifying Party and in any event prior to the expiration of the underlying representations and warranties, if applicable. Except as provided in Section 10.5, the failure by any Indemnified Party so to notify the Indemnifying Party shall not relieve the Indemnifying Party from any Liability that it may have to such Indemnified Party under Section 10.2 or Section 10.3, except to the extent that the Indemnifying Party shall have been actually prejudiced as a result of such failure. If the Indemnifying Party disputes its Liability with respect to such claim, the Indemnifying Party and the Indemnified Party shall proceed in good faith to negotiate a resolution of such dispute and, if not resolved through negotiations, such dispute shall be resolved in accordance with Section 11.10.

          (d) To the extent of any conflict between this Section 10.6 and Section 8.6(e), Section 8.6(e) shall control.

          10.7 Sole Remedy. Each of Buyer and Seller acknowledges and agrees that its sole and exclusive remedy after the First Closing Date with respect to any and all claims and causes of action relating to this Agreement (including the Schedules), the Other Agreements and the Transactions, the Purchased Assets, the Assumed Liabilities and the Shares (other than claims of, or causes of action arising from fraud) shall be pursuant to the indemnification provisions set forth in this Article X or as provided in Section 11.11.

          10.8 Effect of Investigation or Knowledge. Any claim by Buyer or its Affiliates or any of their Representatives for indemnification shall not be adversely affected by any investigation by or opportunity to investigate afforded to Buyer, nor, subject to the limitations set forth in Section 6.9(b), shall such a claim be adversely affected by Buyer’s knowledge on or before any Closing Date of any breach of the type specified in Section 10.2 or of any state of facts that may give rise to such a breach. Subject to the limitations set forth in Section 6.9(b), the waiver of any condition based on the accuracy of any representation or warranty, or on the performance of or compliance with any covenant or obligation, will not adversely affect the right to indemnification, payment of Losses or other remedy based on such representations, warranties, covenants or obligations.

ARTICLE XI.

          11.1 Assignment; Binding Effect. This Agreement shall be binding upon and inure to the benefit of the Parties hereto and their respective successors’ and assigns.

          11.8 Waiver. Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of the party waiving such term or condition. The failure of any Party to enforce any condition or part of this Agreement at any time shall not be construed as a waiver of that condition or part, nor shall it forfeit any rights to future enforcement thereof. Except as provided in Section 9.2, all remedies either under this Agreement or by Law or otherwise afforded, will be cumulative and not in the alternative.

          11.9 Governing Law. This Agreement (including any claim or controversy arising out of or relating to this Agreement) shall be governed by and construed in accordance with the Laws of the State of Delaware without regard to conflict of law principles that would result in the application of any Law other than the Laws of the State of Delaware.

          11.10 Arbitration.

          (a) All disputes, differences, controversies and claims of the Parties arising out of or relating to the Agreement (individually, a “Dispute” and, collectively, “Disputes”), except as otherwise provided under this Agreement, shall be resolved by final and binding arbitration administered by the American Arbitration Association (“AAA”) under its Commercial Arbitration Rules, subject to the provisions of this Section 11.10.

          (b) Following the delivery of a written demand for arbitration by either Party, each of Buyer and Seller shall choose one (1) arbitrator within ten (10) Business Days after the date of such written demand and the two chosen arbitrators shall mutually, within ten (10) Business Days after selection select a third (3^rd) arbitrator (each, an “Arbitrator” and together, the “Arbitrators”), each of whom shall be a retired judge, subject to Section 11.10(i) below, selected from a roster of arbitrators provided by the AAA. If the third (3^rd) Arbitrator is not selected within fifteen (15) Business Days after delivery of the written demand for arbitration (or such other time period as the Parties may agree), the Parties shall promptly request that the commercial panel of the AAA select an independent Arbitrator meeting such criteria.

          (c) The rules of arbitration shall be the Commercial Rules of the American Arbitration Association; provided, however, that notwithstanding any provisions of the

Commercial Arbitration Rules to the contrary, unless otherwise mutually agreed to by Buyer and Seller, the sole discovery available to each Party shall be its right to conduct up to two (2) non-expert depositions of no more than three (3) hours of testimony each.

          (d) The Arbitrators shall render an award by majority decision within three (3) months after the date of appointment, unless the Parties agree to extend such time. The award shall be final and binding upon the Parties.

          (e) Any judicial proceeding arising out of or relating to this Agreement or the relationship of the Parties, including without limitation any proceeding to enforce this section, to review or confirm the award in arbitration, shall be brought exclusively in the Delaware Chancery Court sitting in the county of New Castle, Delaware (the “Enforcing Court”). By execution and delivery of this Agreement, each Party accepts the jurisdiction of the Enforcing Court.

          (f) Each Party shall pay its own expenses in connection with the resolution of Disputes pursuant to this Section, including attorneys’ fees, unless determined otherwise by the Arbitrator.

          (g) The Parties agree that the existence, conduct and content of any arbitration pursuant to this section shall be kept confidential and no Party shall disclose to any Person any information about such arbitration, except in connection with such arbitration or as may be required by Law or by any Regulatory Authority (or any exchange on which such Party’s securities are listed) or for financial reporting purposes in such Party’s financial statements.

          (h) Notwithstanding the foregoing, none of the provisions of this Section 11.10 shall restrict the right of any Party to seek injunctive relief or other equitable remedies, to enjoin any breach or threatened breach of this Agreement or otherwise specifically enforce any provision of this Agreement.

          (i) For purposes of resolving any disputes pursuant to Section 2.8(a)(ii) or Section 2.8(d)(ii), the Arbitrators shall consist of current or former executives with knowledge of and experience in the pharmaceutical industry.

          11.11 Injunctive Relief. Except as set forth in Section 9.2, the Parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement, including Section 8.11, were not performed in accordance with their specific terms or were otherwise breached and that such damages would not be fully compensable by an award of money damages. It is accordingly agreed that, except as set forth in Section 9.2, the Parties hereto shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement without posting a bond or other undertaking, this being in addition to any other remedy to which they are entitled at law or in equity. The parties agree that notwithstanding Section 11.10, any Action brought for an injunction or injunction, or for specific performance shall be heard and exclusively in the Delaware Chancery Court sitting in New Castle County and each Party waives any objection which it may now or hereafter have to the laying of venue of any such proceeding, and irrevocably submits to the jurisdiction of such courts in any such suit, action or proceeding.

          11.12 Headings. The headings of the Sections and subsections of this Agreement are inserted for convenience only and shall not be deemed to constitute a part hereof.

          11.13 Counterparts. This Agreement may be executed in two or more counterparts (including by facsimile or by an electronic scan delivered by electronic mail), each of which shall be deemed to be an original, but all of which, taken together, shall constitute one and the same agreement and shall become effective when counterparts have been signed by each of the Parties hereto delivered to the other Parties, it being understood that all Parties need not sign the same counterpart.

          11.14 Schedules. Buyer agrees that any disclosure by Seller of any item or matter under any Section or subsection in the Schedules delivered by Seller in connection with this Agreement, or in attachments thereto, and documents referred to therein, (a) shall be deemed disclosure for all purposes of Article IV and (b) shall not establish any threshold of materiality or concede the materiality of any matter or item disclosed therein.

          11.15 Construction. The language in all parts of this Agreement shall be construed, in all cases, according to its fair meaning. The Parties acknowledge that each Party and its counsel have reviewed and revised this Agreement and that any rule of construction to the effect that any ambiguities are to be resolved against the drafting Party shall not be employed in the interpretation of this Agreement.
