(i)                   Buyer and its Affiliates shall have complete control and sole discretion with respect to decisions concerning the Exploitation of the Compound and such control and discretion by Buyer and its Affiliates could result in Seller receiving no Milestone Payment whatsoever;

(ii)                neither Buyer nor any of its Affiliates has any duty to Exploit the Compound, to exert any level of efforts in Exploiting the Compound or to achieve the milestone described in Section 2.5(a)  above;

(v)               Seller shall not challenge in any subsequent Action any decision regarding the Exploitation of the Compound made by any director, officer, employee or agent of Buyer or any of its Affiliates in what such individual subjectively believes to be the best interests of Buyer (or such Affiliate), unless such Action constitutes a breach by

15

Buyer of any of its express obligations to make the Milestone Payment under this Section 2.5 .  For the avoidance of doubt, any obligations assumed by Buyer relating to or arising out of the License Agreement shall have no effect on the foregoing provisions of this Section 2.5 , and nothing herein, expressed or implied, shall give or be construed to give the Seller or any of its Affiliates any rights as a third party beneficiary of the License Agreement after the Closing.

Section 2.6.                                  Third Party Consents .  If the assignment or transfer of any asset included in the Purchased Assets or any claim, right or benefit arising thereunder or resulting therefrom, 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 an agreement concerning such asset, claim, right or benefit, or, upon assignment or transfer, would in any way adversely affect the rights of Seller or, upon transfer, Buyer (each, a “ Non-Assignable Right ”), then Seller shall use its commercially reasonable efforts, at Seller’s sole cost and expense, to obtain such consent after the execution of this Agreement until such consent is obtained.  If any such consent cannot be obtained prior to the Closing, then, notwithstanding anything to the contrary in this Agreement or any Related Document, (a) this Agreement and the related instruments of transfer shall not constitute an assignment or transfer of the applicable Non-Assignable Right, and Seller shall use its commercially reasonable efforts, at Seller’s sole cost and expense, to obtain such consent as soon as possible after the Closing; and (b) Seller shall use its commercially reasonable efforts, at its sole cost and expense, to obtain for Buyer substantially all of the practical benefit and burden of such Non-Assignable Right, including by (i) entering into appropriate and reasonable alternative arrangements on terms mutually agreeable to Buyer and Seller and (ii) subject to the consent and control of Buyer, enforcement, at the cost and for the account of Buyer, of any and all rights of Seller against the other party thereto arising out of the breach or cancellation thereof by such other party or otherwise.

(b)                                  Upon the date that is 12 months from the Closing (the “ Escrow Termination Date ”), the Escrow Agent shall, in accordance with the Escrow Agreement, release the remaining amount in the Escrow Fund at such time, less the Outstanding Claim Reserve at such time, to Seller. If at any time after the Escrow Termination Date the Outstanding Claim Reserve, as determined by a court or by mutual agreement of Buyer and Seller, is less than the Escrow Fund at such time, then an amount equal to such difference shall be released to Seller.

16

(c)           For purposes of this Section 2.7 , “ Outstanding Claim Reserve ” as of any date means the sum of all amounts in good faith claimed by Buyer as of such date to be then owed to the Buyer Indemnified Parties in respect of indemnity claims made by the Buyer Indemnified Parties as of such date in accordance with Article VI .

(d)           All funds so released from the Escrow Fund shall include any Escrow Consideration earned thereon.  The amount of any funds released from the Escrow Fund pursuant to Section 2.7(b)  shall, for the avoidance of doubt, be deemed a part of the Purchase Price to the extent permitted by applicable Law.  The Escrow Fund shall be held as a trust fund and shall not be subject to any Lien, and shall be held and disbursed solely for the purposes and in accordance with the terms of this Agreement and the Escrow Agreement.  Upon the final release of all of the Escrow Fund, the Escrow Agreement shall terminate.

Section 2.8.           Purchase Price Allocation .

(a)           The allocation of the Purchase Price among the Purchased Assets and Seller’s obligations under Section 5.1(b)  in accordance with Section 1060 of the Code shall be as set forth on Schedule 2.8(a)  (the “ Purchase Price Allocation ”).  The Purchase Price Allocation shall be appropriately adjusted, based on good faith consultation between Buyer and Seller, in the event of an adjustment to the Purchase Price, including pursuant to Section 2.5 or Article VI .

(b)           Seller and Buyer agree to act in accordance with the Purchase Price Allocation, as adjusted in accordance with Section 2.8(a)  if applicable, in any Tax Return, including any forms or reports required to be filed pursuant to Section 1060 of the Code or any provisions of any comparable Law, unless there has been a final “determination,” as defined in Section 1313(a) of the Code, pursuant to which the allocation is modified.  Buyer and Seller shall cooperate in the preparation of such Tax Returns and file such forms as required by applicable Law.  Neither Buyer nor Seller shall take a position inconsistent therewith upon examination of any Tax Return, in any refund claim, or in any litigation or investigation, without the prior written consent of the other Party, except as required by applicable Law.  In the event that the Purchase Price Allocation is disputed by any Taxing Authority, the Party receiving notice of the dispute shall promptly notify the other Party in writing of such notice and resolution of the dispute.

39

without the prior written consent of the Indemnified Party if (1)  the claimant in such Third Party Claim provides to the Indemnified Party an unqualified release of such Indemnified Party from all liability in respect of such Third Party Claim, (2) such settlement does not involve any injunctive relief binding upon the Indemnified Party, (3) such settlement does not encumber any of the material assets of the Indemnified Party or impose any restriction or condition that would apply to or materially affect such Indemnified Party or the conduct of such Indemnified Party’s businesses and (4) such settlement does not involve any admission of liability or wrongdoing by the Indemnified Party; and provided , further , that the Indemnified Party may settle such Third Party Claim without the prior written consent of the Indemnifying Party if such settlement satisfies the criteria set forth in the foregoing clauses (1) through (4), mutatis mutandis, with respect to the Indemnifying Party, and such Third Party Claim (x) seeks an injunction or other equitable relief or (y) involves money damages which are, taken together with the reasonably estimated costs of defense thereof, greater than the Cap, if applicable (it being understood that any such settlement without the Indemnifying Party’s prior written consent shall not be evidence in determining whether the Indemnifying Party must provide indemnification to, or hold harmless, the Indemnified Party with respect to such Third Party Claim).

(b)           In order for an Indemnified Party to be entitled to any indemnification provided for under this Agreement other than in respect of, arising out of or involving a Third Party Claim, such Indemnified Party shall deliver written notice of such claim with reasonable promptness to the Indemnifying Party (including in such notice a brief description of the applicable claim(s), including damages in good faith sought or estimated, to the extent actually known by such Indemnified Party); provided , however , that failure to give such notification shall not affect the indemnification provided under Section 6.1 or 6.2 except to the extent the Indemnifying Party has been actually prejudiced as a result of such failure (it being understood that the failure to have released the applicable portion of the Escrow Amount at the expected release time due to an inability to ascertain the amount of Loss owed to a Buyer Indemnified Party at such time shall not constitute such prejudice).  If the Indemnifying Party does not notify the Indemnified Party within 20 Business Days following its receipt of such notice that the Indemnifying Party disputes the indemnity claimed by the Indemnified Party under Section 6.1 or 6.2 such indemnity claim specified by the Indemnified Party in such notice shall be conclusively deemed a liability to be indemnified under Section 6.1 or 6.2 and the Indemnified Party shall be indemnified for the amount of the Losses stated in such notice to the Indemnified Party on demand or, in the case of any notice in which the Losses (or any portion thereof) are estimated, on such later date when the amount of such Losses (or such portion thereof) becomes finally determined, but in all cases subject to the Indemnity Threshold and the Cap, to the extent applicable, and the other limitations set forth herein.

Section 6.5.           Termination of Indemnification .  (a)  The obligations to indemnify and hold harmless an Indemnified Party hereto (i) pursuant to Sections 6.1(a)(i)  and 6.2(a)(i) , shall terminate when the applicable representation or warranty terminates pursuant to Section 6.5(b)  and (ii) pursuant to the other clauses of Sections 6.1(a)  and 6.2(a)  shall terminate on the expiration of any statute of limitations applicable thereto; provided , however , that as to clause (i) above such obligation to indemnify and hold harmless shall not terminate with respect to any Losses as to which the Indemnified Party shall have, before the expiration of the applicable period, previously made a claim by delivering a written notice of such claim to the Indemnifying Party in accordance with Section 6.4 .

40

(b)           All representations, warranties, covenants and obligations contained in this Agreement shall survive the consummation of the transactions contemplated by this Agreement; provided , however , that, except in the case of intentional fraud, (i) the Specified Representations and the representations and warranties set forth in Sections 4.1 , 4.2(a)  and 4.5 shall terminate on the expiration of the statute of limitations applicable thereto, and (ii) the representations and warranties contained in this Agreement other than the Specified Representations and the representations and warranties set forth in Sections 4.1 , 4.2(a)  and 4.5 shall terminate on the date that is 15 months after the Closing Date; provided , further , such covenants and agreements of the Parties shall survive until they are fully performed or, if earlier, until the expiration thereof set forth in the terms of such covenants and agreements.

Section 6.6.           Exclusive Remedies .  Buyer and Seller acknowledge and agree that after the Closing, the indemnification provisions of this Article VI shall be the sole and exclusive remedies of Buyer and Seller for any breach of the representations or warranties or nonperformance of or default under any covenants or agreements of Buyer or Seller contained in this Agreement or any Related Document, or otherwise in connection with the Contemplated Transactions (other than (i) claims for equitable relief under Section 7.8 and (ii) claims of, or causes of action arising from, intentional fraud).
