          (c) The Company shall acquire the Acquired Assets free and clear of all liabilities, obligations and commitments of Lucky Parent, any Seller or any of their affiliates, other than the Assumed Liabilities, and free and clear of all

Liens, other than Permitted Liens. For clarity, none of Jupiter Parent or any of its affiliates (other than the Company) shall assume or be liable for any liabilities, commitments or obligations of Lucky Parent, any Seller or any of their affiliates (whether they may be Assumed Liabilities, Excluded Liabilities or otherwise).

          SECTION 1.04. Consents of Third Parties. (a) Notwithstanding anything in this Agreement to the contrary, this Agreement shall not constitute an agreement to assign any Acquired Asset if an attempted assignment thereof, without the consent of a third party, would constitute a breach or other contravention of the rights of such third party, would be ineffective with respect to any party to a Contract concerning such Acquired Asset, or would in any way adversely affect the rights of any Seller or, upon transfer, the Company under such Acquired Asset. If any transfer or assignment by any Seller to, or any assumption by the Company of, any interest in, or liability, obligation or commitment under, any Acquired Asset requires the consent of a third party, then such assignment or assumption shall be made subject to such consent being obtained. To the extent any Acquired Asset may not be assigned to the Company by reason of the absence of any such consent and, to the extent applicable, Jupiter Parent and the Company waive Section 6.02(c) with respect to such consent, the Company shall not be required to assume any Assumed Liabilities arising under such Acquired Asset.

          (b) If any consent referred to in Section 1.04(a) is not obtained prior to the Closing and, to the extent applicable, Jupiter Parent and the Company waive Section 6.02(c) with respect to such consent, Lucky Parent, each applicable Seller and the Company shall cooperate (at their own expense) in any lawful and reasonable arrangement reasonably proposed by the Company under which the Company shall obtain the rights, benefits and economic claims under the Acquired Asset with respect to which such consent has not been obtained in accordance with this Agreement. Such reasonable arrangement may include (i) the subcontracting, sublicensing or subleasing to the Company of any and all rights of such Seller against the other party to such third-party agreement arising out of a breach or cancellation thereof by the other party and (ii) the enforcement by such Seller of such rights. To the extent, and only to the extent, the Company is able to receive the rights, benefits and economic claims under such Acquired Asset, the Company shall be responsible for the Assumed Liabilities, if any, arising under such Acquired Asset.

          SECTION 1.05. Securities Compliance. The Company Stock to be received by Lucky Collaboration Subsidiary pursuant to this Agreement is being acquired for Lucky Collaboration Subsidiary’s own account, for investment and not with a view to or for resale in connection with any “distribution” thereof as such term is used in connection with the registration provisions of the Securities Act of 1933, as amended (the “Securities Act”). Lucky Collaboration Subsidiary acknowledges that Jupiter Parent and the Company have informed it that the shares of Company Stock deliverable pursuant to this Agreement will not be registered under the Securities Act and may not be sold until, among other things, such shares have been registered or until an exemption from registration is available. Lucky Collaboration Subsidiary

acknowledges that it has sufficient knowledge and experience with respect to financial and business matters as is necessary for making an informed decision on the merits and risks of an investment in the Company Stock. Lucky Collaboration Subsidiary further acknowledges that the Company Stock deliverable hereunder is subject to additional restrictions (including with respect to transferability) under the Shareholders’ Agreement.

The Seller Disclosure Letter shall be arranged in numbered and lettered sections and subsections corresponding to the numbered and lettered sections and subsections contained in this Article III, and the disclosure in any section or subsection shall be deemed to qualify other sections and subsections in this Article III to the extent (and only to the extent) that it is reasonably apparent from the face of such disclosure that such disclosure also qualifies or applies to such other sections and subsections (except with respect to disclosures relating to the Collaboration Agreement, which shall not be deemed to qualify any other section unless actually disclosed in such other section).

          SECTION 3.01. Organization, Standing and Power. Lucky Parent and each Seller are duly organized, validly existing and in good standing under the laws of their respective jurisdictions of organization and have full corporate or other power and authority to own, lease or otherwise hold their respective properties and assets and to conduct the Business as currently conducted. Each Seller is duly qualified to do business as a foreign corporation in each jurisdiction where (x) the character of the Acquired Assets held by it or the nature of the Business make such qualification necessary for it to conduct the Business as currently conducted or (y) the failure to so qualify has had or could reasonably be expected to have, individually or in the aggregate, a Seller Material Adverse Effect. Each Seller has delivered to the Company or its counsel true and complete copies of the certificate of incorporation and by-laws (or other comparable documents) of such Seller, in each case as amended through the date of this Agreement. Each Seller is a direct or indirect wholly owned subsidiary of Lucky Parent.

The execution and delivery by Lucky Parent and each Seller of this Agreement and the Specified Collaboration Documents to which each of them is, or is specified to be, a party and the consummation by Lucky Parent and each Seller of the Acquisition and the other transactions contemplated hereby and thereby have been duly authorized by all necessary corporate or other action on the part of Lucky Parent and each Seller, and no other proceedings on the part of

Lucky Parent or any Seller are necessary to authorize this Agreement and the Specified Collaboration Documents or the consummation of the Acquisition and the other transactions contemplated hereby or thereby.

ARTICLE VII

Termination, Amendment and Waiver

          SECTION 7.01. Termination. (a) Notwithstanding anything to the contrary in this Agreement, this Agreement may be terminated and the Acquisition and the other transactions contemplated by this Agreement abandoned at any time prior to the Closing:

          (i) by written consent of Lucky Parent, each Seller, Jupiter Parent and the Company;

          (ii) by either Jupiter Parent and the Company, on one hand, or the Sellers and Lucky Parent, on the other hand, if the Closing shall not have occurred on or before September 15, 2009 (the “Outside Date”); provided, that if on the Outside Date, the condition set forth in Section 6.01(a) has not been fulfilled but each other condition has been fulfilled or waived to the satisfaction of each of the parties, any party may by notice to each of the other parties extend the Outside Date until the date that is 75 days after the Outside Date; provided, however, that the right to terminate this Agreement or extend the Outside Date pursuant to this Section 7.01(a)(ii) will not be available to a party if the failure of the Closing to occur on or before the Outside Date is due to a breach by any such party (or any of its affiliates) of its (or any of their) obligations under this Agreement;

          (iii) by Lucky Parent or Sellers, if Jupiter Parent or the Company breaches or fails to perform any of its covenants or agreements contained in this Agreement, or if any of the representations or warranties of Jupiter

Parent or the Company contained herein fails to be true and correct, which breach or failure (A) would give rise to the failure of a condition set forth in Section 6.03(a) or Section 6.03(b) and (B) is not capable of being cured by the Outside Date;

          (iv) by Jupiter Parent or the Company, if either Lucky Parent or any Seller breaches or fails to perform any of its covenants or agreements contained in this Agreement, or if any of the representations or warranties of Lucky Parent or any Seller contained herein fails to be true and correct, which breach or failure (A) would give rise to the failure of a condition set forth in Section 6.02(a) or Section 6.02(b) and (B) is not capable of being cured by the Outside Date; or

          (v) by either Jupiter Parent and the Company, on one hand, or the Sellers and Lucky Parent, on the other hand, if any Restraint shall be in effect and shall have become final and nonappealable.

               (b) In the event of termination by Lucky Parent, any Seller, Jupiter Parent or the Company pursuant to this Section 7.01, written notice thereof shall forthwith be given to the other and the transactions contemplated by this Agreement shall be terminated, without further action by any party. If the transactions contemplated by this Agreement are terminated as provided herein:

Nothing in this Section 7.02 shall be deemed to release any party from any liability for any breach by such party of the terms and provisions of this Agreement or to impair the right of any party to compel specific performance by any other party of its obligations under this Agreement.

          SECTION 7.03. Amendments and Waivers. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto. By an instrument in writing Jupiter Parent and the Company, on the one hand, or Lucky Parent and each Seller, on the other hand, may waive compliance by the other party with any term or provision of this Agreement that such other party was or is obligated to comply with or perform.

ARTICLE VIII

Indemnification

          SECTION 8.01. Indemnification by Lucky Parent and each Seller. Lucky Parent and each Seller, jointly and severally, shall indemnify Jupiter Parent, the Company, their affiliates and each of their respective Representatives against, and hold them harmless from, any Losses, as incurred (payable promptly upon written request), arising from, in connection with or otherwise with respect to:

     (a) any inaccuracy in, or breach of, any representation or warranty of Lucky Parent or any Seller contained in this Agreement or any document delivered in connection herewith (it being agreed and acknowledged by the parties that for purposes of determining the existence of any such inaccuracy or breach or the amount of any Loss with respect thereto, the representations and warranties of Lucky Parent and the Sellers shall be deemed not qualified by any references therein to materiality or Seller Material Adverse Effect);

     (b) any failure by Lucky Parent or any Seller to perform any covenant, agreement, obligation or undertaking contained in this Agreement or in any document delivered in connection herewith;

     (c) any Excluded Liability; and

     (d) any and all actions, suits, proceedings, demands, assessments, judgments, damages, awards, costs and expenses (including third-party fees and expenses) incident to any of the foregoing or incurred in connection with the enforcement of the rights of any such indemnified party with respect to the foregoing.

          SECTION 8.02. Indemnification by Jupiter Parent and the Company. (a) Jupiter Parent and the Company, jointly and severally, shall indemnify Lucky Parent, each Seller, their affiliates and each of their respective Representatives against, and hold them harmless from, any Losses, as incurred (payable promptly upon written request), for or on account of or arising from or in connection with or otherwise with respect to:

          (i) any inaccuracy in, or breach of, any representation or warranty of Jupiter Parent or the Company contained in this Agreement or any document delivered in connection herewith (it being agreed and

acknowledged by the parties that for purposes of determining the existence of any such inaccuracy or breach or the amount of any Loss with respect thereto, the representations and warranties of Jupiter Parent and the Company shall be deemed not qualified by any references therein to materiality or Company Material Adverse Effect);

          (ii) any failure by Jupiter Parent or the Company to perform any covenant, agreement, obligation or undertaking contained in this Agreement or in any document delivered in connection herewith; and

          (iii) any and all actions, suits, proceedings, demands, assessments, judgments, damages, awards, costs and expenses (including third-party fees and expenses) incident to any of the foregoing or incurred in connection with the enforcement of the rights of any such indemnified party with respect to the foregoing.

     (b) the Company shall indemnify Lucky Parent, each Seller, their affiliates and each of their respective Representatives against, and hold them harmless from, any Losses, as incurred (payable promptly upon written request), for or on account of or arising from or in connection with or otherwise with respect to any Assumed Liability and any and all actions, suits, proceedings, demands, assessments, judgments, damages, awards, costs and expenses (including third-party fees and expenses) incident to, or incurred in connection with the enforcement of the rights of any such indemnified party with respect to any Assumed Liability.

Notwithstanding the foregoing, the parties agree that any Losses incurred by Lucky Parent or any of its subsidiaries which are indemnifiable pursuant to this Section 8.02 shall be paid to the applicable party (or its designee).

          SECTION 8.03. Termination of Indemnification. Except with respect to any fraud, intentional misrepresentation, intentional misconduct or intentional concealment by or on behalf of any party, such party’s obligations to indemnify and hold harmless any other party pursuant to Section 8.01(a) (other than with respect to any inaccuracy in, or breach of, any representation or warranty contained in Sections 3.01, 3.02, 3.03, 3.05, 3.07(b) and 3.20) or Section 8.02(a) (other than with respect to any inaccuracy in, or breach of, any representation or warranty contained in Sections 4.01, 4.02 and 4.03) shall, in each case, terminate on the date that is two years after the Closing Date (except in the case of any Specified Cap Indemnification Obligation, which shall terminate on the date that is five years after the Closing Date); provided, however, that such obligations to indemnify and hold harmless shall not terminate with respect to any item as to which the applicable indemnified party shall have, before the expiration of the applicable period, previously made a claim by delivering a notice of such claim pursuant to Section 8.04 to the applicable indemnifying party, which notice shall specify the basis of the claim in reasonable detail to the extent known to the indemnified party. Any other obligation to indemnify and hold harmless any party shall terminate upon the expiration of the relevant statute of limitations, taking into account

extensions thereof; provided, however, that such obligations shall not terminate with respect to any item as to which the applicable indemnified party has, before the expiration of the relevant period, taking into account extensions thereof, previously made a claim by delivering a notice of such claim pursuant to Section 8.04 to the applicable indemnifying party, which notice shall specify the basis of the claim in reasonable detail to the extent known to the indemnified party.

          SECTION 8.04. Procedures. (a) Third Party Claims. If a claim by a third party is made against a party hereto or any of its affiliates (the “indemnified party”) in respect of, arising out of or involving a matter for which the indemnified party is entitled to be indemnified by another party hereto (the “indemnifying party”) pursuant to this Article VIII (a “Third Party Claim”), such indemnified party must notify the indemnifying party in writing of the Third Party Claim promptly following receipt by such indemnified party of written notice of the Third Party Claim, which notice shall specify the basis of the claim in reasonable detail to the extent known to the indemnified party; provided, however, that failure to give such notification shall not affect the indemnification provided hereunder except to the extent (and only to the extent) the indemnifying party shall have been actually and materially prejudiced as a result of such failure. Thereafter, the indemnified party shall deliver to the indemnifying party, promptly following 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) Assumption. 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; provided, however, that such counsel is not reasonably objected to by the indemnified 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 (except as provided below). If the indemnifying party assumes such defense, the indemnified party shall have the right to participate in the defense thereof and to employ counsel, separate from the counsel employed by the indemnifying party, at its own expense (except that the legal expenses of such separate counsel shall be borne by the indemnifying party if (i) the indemnified party shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the indemnifying party or (ii) the named parties in any Proceeding (including any impleaded parties) related to such Third Party Claim include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them). The indemnifying party shall be liable for the reasonable fees and expenses of counsel employed by the indemnified party for any period during which the indemnifying party has not assumed the defense thereof. 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. If the indemnifying party assumes the defense of a Third Party Claim, (A) the indemnified party shall agree to any settlement, compromise or discharge of a Third Party Claim that the indemnifying party may recommend and that by its terms obligates the indemnifying party to pay the full amount of the liability in connection with such Third Party Claim, which releases the indemnified party completely in connection with such Third Party Claim and that would not otherwise adversely affect the indemnified party, and (B) the indemnified party shall not enter into any settlement, compromise or discharge of a Third Party Claim without the prior written consent of the indemnifying party (which shall not be unreasonably withheld, conditioned or delayed). Notwithstanding the foregoing, (i) the indemnifying party shall not be entitled to assume the defense of any Third Party Claim (and shall be liable for the reasonable fees and expenses of counsel incurred by the indemnified party in defending such Third Party Claim) if (x) the Third Party Claim seeks an order, injunction or other equitable relief or relief for other than money damages against the indemnified party that the indemnified party reasonably determines, after conferring with its outside counsel, cannot be separated from any related claim for money damages or (y) the indemnified party reasonably believes itself to be exposed, in the event that such Third Party Claim is not resolved in the indemnified party or indemnifying party’s favor, to Losses in excess of amounts reasonably expected to be received from the indemnifying party and (ii) the Company shall be entitled to assume the defense with respect to any Third Party Claim that relates to any Intellectual Property of the Company or any of its affiliates (including, after the Closing, the Business Intellectual Property) or that is brought by Wyeth or any of its affiliates in respect of the Collaboration Agreement; provided that, in the case of both clauses (i) and (ii) above, the Company shall not settle any Third Party Claim without the indemnified party’s prior written consent (such consent not to be unreasonably withheld or delayed). In the case of any Third Party Claim referred to in clause (i)(x) of the immediately preceding sentence, if such equitable relief or other relief portion of such Third Party Claim can be so separated from that for money damages, the indemnifying party shall be entitled to assume the defense of the portion of such Third Party Claim relating to money damages.

          (c) Other Claims. In the event any indemnified party should have a claim against any indemnifying party under Section 8.01 or 8.02 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. Subject to Sections 8.03 and 8.05, 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 8.01 or 8.02, except to the extent that the indemnifying party demonstrates that it has been actually and materially

prejudiced by such failure. If the indemnifying party does not notify the indemnified party within thirty (30) days following its receipt of such notice that the indemnifying party disputes its liability to the indemnified party under Section 8.01 or 8.02, such claim specified by the indemnified party in such notice shall be conclusively deemed a liability of the indemnifying party under Section 8.01 or 8.02 and the indemnifying party shall pay the amount of such liability to the indemnified party on demand or, in the case of any notice in which the amount of the claim (or any portion thereof) is estimated, on such later date when the amount of such claim (or such portion thereof) becomes finally determined.

          (d) Quantifying Company Losses. Except as set forth in the proviso to this sentence and notwithstanding anything else in this Agreement to the contrary, the parties agree that any Losses incurred by the Company or any of its subsidiaries which are indemnifiable pursuant to Section 8.01 shall be paid to Jupiter Parent (or its designees); provided, however, that the Company shall receive all payment (or portions thereof) in respect of Losses indemnifiable pursuant to Section 8.01 to the extent, and only to the extent, (i) such payment (or portion thereof) is made at any time prior to the Positive Cash Flow Date and (ii) such Losses were funded or covered by the Company with the proceeds of a repayment of the Loan by Jupiter Sub-2. In the event of any Loss incurred by the Company or any of its subsidiaries for which the Company or such subsidiary is entitled to indemnification under Section 8.01, (A) to the extent such Loss is paid, funded, satisfied or discharged directly or indirectly, in whole or in part, with the proceeds of a capital contribution, loan, repayment of the Loan by Jupiter Sub-2 or other payment or advance by Jupiter Parent or any of its affiliates (other than the Company and its subsidiaries) (any of the foregoing, a “Loss Funding Contribution”), the liability of Lucky Parent and the Sellers in respect of the portion of such Loss so funded, satisfied or discharged shall not exceed the amount of such Loss Funding Contribution and (B) to the extent such Loss is paid, funded, satisfied or discharged with any other asset of the Company or any of its subsidiaries, or the Company or any of its subsidiaries is required to concede anything of value in satisfaction or discharge of such Loss other than cash in respect of a Loss Funding Contribution, the liability of Lucky Parent and the Sellers in respect of such Loss shall not exceed 50.1% of the aggregate economic value of such Loss. For any Loss in respect of which both subclauses (A) and (B) of this clause (d) would apply, such Loss shall be addressed first by the application of subclause (A), with any remaining Loss being addressed by the application of subclause (B).

          (e) Deductible and Limitations of Lucky Parent and the Sellers. Notwithstanding any other provision of this Article VIII, Lucky Parent and the Sellers shall not have any liability:

          (i) under clause (a) of Section 8.01 (and, to the extent relating thereto, clause (d) of Section 8.01) for any Losses unless and until the aggregate amount of all such Losses exceeds $3,500,000, in which case

Lucky Parent or any such Seller shall be liable for all such Losses only in excess of such amount; and

          (ii) under clause (a) of Section 8.01 (and, to the extent relating thereto, clause (d) of Section 8.01), individually or in the aggregate, in excess of (x) $140,000,000 in the case of the General Cap Indemnification Obligations (the “General Cap”) or (y) $350,000,000 in the case of the Specified Cap Indemnification Obligations (the “Specified Cap”); provided, that the General Cap shall be reduced by any amount in excess of $210,000,000 actually paid in respect of the Specified Cap Indemnification Obligations and the Specified Cap shall be reduced by any amount actually paid in respect of the General Cap Indemnification Obligations; provided, further, that the limitations set forth in this clause (ii) shall not apply to any claim for indemnification to the extent arising out of an inaccuracy or breach of any representation or warranty contained in Sections 3.01, 3.02, 3.03, 3.05, 3.07(b) or 3.20 or to any Loss incurred due to fraud, intentional misrepresentation, intentional misconduct or intentional concealment by or on behalf of Lucky Parent or any Seller. In no event shall the liability of Lucky Parent and the Sellers pursuant to clause (a) of Section 8.01 (and, to the extent relating thereto, clause (d) of Section 8.01) include Losses to the extent based on lost profits or on diminution in the value (or prospective value) of the Company (or an indemnified party’s or its affiliate’s investment in the Company); provided, however, that the foregoing shall not limit or otherwise affect the liability of Lucky Parent and the Sellers thereunder in respect of the Losses suffered by Jupiter Parent or the Company involving the expenditure of money or the loss or transfer of assets (including rights in respect of Intellectual Property) or other concession of value (including the grant of any royalty or similar right).

               (f) Deductible of Jupiter Parent and the Company. Notwithstanding any other provision of this Article VIII, Jupiter Parent and the Company shall not have any liability under clause (i) of Section 8.02(a) (and, to the extent relating thereto, clause (iii) of Section 8.02(a)) for any Losses unless and until the aggregate amount of all such Losses exceeds $3,500,000, in which case Jupiter Parent or the Company shall be liable for all such Losses only in excess of such amount. In no event shall the liability of Jupiter Parent and the Company pursuant to clause (i) of Section 8.02(a) (and, to the extent relating thereto, clause (iii) of Section 8.02(a)) include Losses to the extent based on lost profits or on diminution in the value (or prospective value) of the Company (or an indemnified party’s or its affiliate’s investment in the Company); provided, however, that the foregoing shall not limit or otherwise affect the liability of Jupiter Parent and the Company thereunder in respect of the Losses suffered by Lucky Parent or the Sellers involving the expenditure of money or the loss or transfer of assets (including rights in respect of Intellectual Property) or other concession of value (including the grant of any royalty or similar right).

          SECTION 8.05. Survival of Representations and Covenants. (a) The representations, warranties, covenants and agreements contained in this Agreement and in any document delivered in connection herewith shall survive the Closing and remain in full force and effect until the indemnification obligation therefor terminates in accordance with Section 8.03.

          (b) The obligations of Lucky Parent and each Seller under Section 8.01 and the obligations of Jupiter Parent and the Company under Section 8.02 shall not be affected by any knowledge by any indemnified party at or prior to the Closing of any breach of representation or warranty, whether such knowledge came from Lucky Parent, a Seller, Jupiter Parent, the Company or any other person, or any waiver of Section 6.02 or 6.03.

          SECTION 8.06. Tax Treatment of Indemnification Payments. For all Tax purposes, the parties agree to treat, to the extent permitted by Applicable Law, any indemnity payment under this Agreement as an adjustment to the Purchase Price.

          SECTION 8.07. Exemplary or Punitive Damages. To the extent permitted by Applicable Law, none of the parties hereto shall assert, and each of the parties hereto hereby waives, any claim against any other party hereto, on any theory of liability, for exemplary, punitive or special damages arising out of, in connection with, or as a result of, this Agreement or any indemnification claim, except to the extent payable to a Third Party.

          SECTION 8.08. Claims under Collaboration Agreement; Turnover. (a) In the event of any Loss incurred by the Company or any of its subsidiaries (other than any Loss arising from the gross negligence or willful misconduct of Lucky Parent or any of its affiliates) for which (i) the Company or such subsidiary is entitled to indemnification under Section 8.01 and (ii) the Company or such subsidiary is entitled to indemnification from, or has a bona fide claim against, Wyeth under the Collaboration Agreement, the Company or such subsidiary, as applicable, shall use reasonable efforts to pursue recovery of such Loss from Wyeth before the Company or such subsidiary shall be entitled to indemnification under Section 8.01 (it being agreed that nothing in this Section 8.08 shall limit the Company’s or such subsidiary’s right to indemnification under this Article in the event, and to the extent, full recovery of such Loss is not obtained from Wyeth (including with respect to costs and expenses incurred in connection with pursuing recovery from Wyeth, and, for clarity, the applicable survival period for indemnification under Section 8.03 in respect of such Loss shall be tolled for so long as the Company or such subsidiary is pursuing recovery from Wyeth)).

          (b) In the event any person receives an indemnification payment under this Article VIII in respect of any Loss and thereafter such person receives a payment in respect of such Loss by way of insurance proceeds, other indemnification or any other available remedy, then, in each such case, such person shall promptly pay-over to the applicable indemnifying party under this Article VIII any and all amounts so recovered from any such alternative sources

to the extent necessary so that such person does not recover more than the entire amount of the Loss at issue (or, if less, to the extent necessary so that the applicable indemnifying party recovers the entire amount of indemnification paid hereunder to such person in respect of such Loss). In furtherance of the foregoing, and subject only to Section 8.08(a), no person entitled to indemnification hereunder shall be required to first pursue recovery of a Loss from any such alternative sources as a condition to receiving indemnification under this Article VIII.

          SECTION 8.09. Sole Remedy. In the absence of fraud, intentional misrepresentation, intentional misconduct or intentional concealment, the indemnification provisions set forth herein shall constitute the sole remedy for any breach of this Agreement or for any Losses arising out of or relating to this Agreement, and applicable indemnified parties expressly waive any other remedy with respect to such Losses, whether in contract or tort or otherwise, including any right to rescind this Agreement; provided that this Section 8.09 shall not limit in any way the rights of any party pursuant to or under the express terms of any Transaction Document.
