SECTION 8.
SURVIVAL AND INDEMNIFICATION

     8.1 Survival of Representations. The representations and warranties contained in this Agreement, the certificates delivered by Seller and Purchaser pursuant to Section 2.11.1(b) and 2.11.2(c), respectively, shall survive the Closing and remain in full force and effect until the **** anniversary of the Closing Date; provided, however, that if notice of any claim for indemnification pursuant to Section 8.2 or Section 8.3 shall have been given prior to the first anniversary of the Closing Date, the relevant representations and warranties shall survive for purposes of such claim until such time as such claim is finally resolved.

     8.2 Indemnification by Seller. Seller shall indemnify Purchaser and its Affiliates and their respective, officers, directors, employees, stockholders, agents and Representatives against, and hold them harmless from, any Losses, to the extent arising from:

          8.2.1 any breach of any representation or warranty of Seller contained in this Agreement or the certificate delivered by Seller pursuant to Section 2.11.1(b);

          8.2.2 any breach of any covenant of Seller contained in this Agreement;

          8.2.3 any Excluded Liabilities; and

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

     8.3 Indemnification by Purchaser. Purchaser shall indemnify Seller and its Affiliates and their respective officers, directors, employees, stockholders, agents and Representatives against, and agrees to hold them harmless from, any Losses, to the extent arising from:

          8.3.1 any breach of any representation or warranty of Purchaser contained in this Agreement or the certificate delivered by Purchaser pursuant to Section 2.11.2(c);

          8.3.2 any breach of any covenant of Purchaser contained in this Agreement;

          8.3.3 any Assumed Liability; and

          8.3.4 any fees, expenses or other payments incurred or owed by Purchaser to any brokers, financial advisors or other comparable Persons retained or employed by it in connection with the Transactions.

     8.4 Procedures. 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 under this Agreement except to the extent the Indemnifying Party shall have been actually prejudiced as a result of such failure (except that the Indemnifying Party shall not be liable for any expenses incurred during the period in which the Indemnified Party failed to give such notice). 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.

          8.4.1 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. 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, 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 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 (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 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 and Representatives available on a mutually convenient basis to provide additional information and explanation of any material provided under this Agreement or other matters reasonably related to such Third Party Claim. 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). If the Indemnifying Party assumes the defense of a Third Party Claim, 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 Losses 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 materially adversely affect the Indemnified Party.

          8.4.2 In the event any Indemnified Party should have a claim against any Indemnifying Party under Section 8.2 or 8.3 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, but in any event not later than fifteen (15) Business Days after the Indemnified Party determines that it has or could have a claim to indemnification under this Agreement, stating the amount of Loss, if known, and method of computation thereof, and containing a specific reference to the provisions of this Agreement in respect of which such right of indemnification is claimed or arises. The failure by any Indemnified Party so to notify the Indemnifying Party shall not relieve the Indemnifying Party from any indemnification obligation that it may have to such Indemnified Party under Section 8.2 or 8.3, as applicable, except to the extent that the Indemnifying Party is prejudiced by such failure. If the Indemnifying Party disputes that it has an indemnification obligation with respect to such claim, the Indemnifying Party shall deliver notice of such dispute with reasonable promptness and the Indemnifying Party and the Indemnified Party shall proceed in good faith to negotiate a resolution of such dispute for a period of thirty (30) days following the receipt by the Indemnified Party of such dispute notice. If the Indemnified Party and the Indemnifying Party have not resolved such dispute during such time period through good faith negotiations, such dispute shall be resolved by litigation in an appropriate court of competent jurisdiction or other mutually agreeable non-judicial dispute resolution mechanism.

     8.5 Certain Limitations on Indemnification Obligations. ****

     8.6 Sole Remedy. Except as otherwise specifically provided in this Agreement or in the BSAA Agreement, each of the Parties acknowledge and agree that its sole and exclusive remedy after the Closing with respect to any and all claims and causes of action under or that are reasonably related to this Agreement, the Transactions, the NK-1 Program, the Purchased Assets and the Assumed Liabilities (other than claims of, or causes of action arising from, fraud, other tortious acts, or relating to breaches of covenants requiring performance after the Closing Date) shall be pursuant to the indemnification provisions set forth in this Section 8. In furtherance of the foregoing, each of the Parties hereby waives, from and after the Closing, to the fullest extent permitted under applicable Law, any and all rights, claims and causes of action under or that are reasonably related to this Agreement, the Transactions, the NK-1 Program, the Purchased Assets and the Assumed Liabilities (other than claims of, or causes of action arising from, fraud, other tortious acts, or relating to breaches of covenants requiring performance after the Closing Date) it may have against any other Party arising under or based upon any applicable Law or arising under or based upon common law or otherwise (except pursuant to the indemnification provisions set forth in Section 8.2 or 8.3, as applicable).

     8.7 Limitation on Liability. EXCEPT WITH RESPECT TO THIRD PARTY CLAIMS, THE INDEMNIFICATION OBLIGATIONS OF THE PARTIES SHALL NOT EXTEND TO INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES, INCLUDING NK-1 PROGRAM INTERRUPTION, LOST PROFITS, LOSS OF USE, DAMAGE TO GOODWILL OR LOSS OF THE NK-1 PROGRAM.

Any Party may give the other Parties written notice of any dispute not resolved in the normal course of business. Within ten (10) days after delivery of the notice, the receiving Party shall submit to the other Party a written response.

Unless otherwise agreed, the Parties will select a mediator from the CPR Panels of Distinguished Neutrals.

          9.6.4 Any dispute which has not been resolved by mediation as provided in Section 9.6.2 within forty-five (45) days after initiation of the mediation procedure shall be finally resolved by arbitration in accordance with the CPR Rules for Non-Administered Arbitration then currently in effect by a sole arbitrator; provided, however, that if one Party fails to participate in either the negotiation or mediation as provided in Section 9.6.1 or 9.6.2, the other Parties can commence arbitration prior to the expiration of the time periods set forth above.

          9.8.1 by the mutual written consent of the Parties;

          9.8.2 by the Purchaser by written notice to the Seller if the Closing has not occurred on or prior to **** after the Execution Date, provided that the failure of the Closing to occur by such date is not attributable in whole or in part to a failure of the Purchaser to fulfill any of its obligations under this Agreement;

          9.8.3 by any Party, by written notice to the other Parties if a court of competent jurisdiction or governmental, regulatory or administrative agency or commission shall have issued an order, decree or ruling or taken any other action, in each case permanently restraining, enjoining or otherwise prohibiting the transactions contemplated by this Agreement, and such order, decree, ruling or other action shall have become final and nonappealable; or
