Section 8.2Notice of Claims.  If either a Buyer Indemnified Party, on the one hand, or a Seller Indemnified Party, on the other hand (such Buyer Indemnified Party on the one hand and such Seller Indemnified Party on the other hand being hereinafter referred to as an “Indemnified Party”), has suffered or incurred any Losses for which indemnification may be sought under this ‎Article 8, the Indemnified Party shall so notify the other party from whom indemnification is sought under this ‎Article 8 (the “Indemnifying Party”) promptly in writing describing such Loss, the amount or estimated amount thereof, if known or reasonably capable of estimation, and the method of computation of such Loss, all with reasonable particularity and containing a reference to the provisions of this Agreement in respect of which such Loss shall have occurred.  If any claim, action, suit or proceeding is asserted or instituted by or against a third party

24

​

with respect to which an Indemnified Party intends to claim any Loss under this ‎Article 8, such Indemnified Party shall promptly notify the Indemnifying Party of such claim, action, suit or proceeding and tender to the Indemnifying Party the defense of such claim, action, suit or proceeding.  A failure by an Indemnified Party to give notice and to tender the defense of such claim, action, suit or proceeding in a timely manner pursuant to this ‎Section 8.2 shall not limit the obligation of the Indemnifying Party under this ‎Article 8, except to the extent such Indemnifying Party is actually prejudiced thereby.

Section 8.3Limitations on Liability.  Other than with respect to Excluded Liabilities and Obligations, or any Losses due to any fraud, willful misconduct, intentional misrepresentation or intentional breach, no party hereto shall be liable for any consequential, punitive, indirect, special or incidental damages, under this ‎Article 8 (and no claim for indemnification hereunder shall be asserted) as a result of any breach or violation of any covenant or agreement of such party (including under this ‎Article 8) in or pursuant to this Agreement. Notwithstanding the foregoing, the Buyer shall be entitled to make indemnification claims, in accordance with the procedures set forth in this ‎Article 8, for Losses that include any portion of the Purchased Receivables that the Buyer was entitled to receive but did not receive timely or at all due to any indemnifiable events under this Agreement, and such portion of the Purchased Receivables shall not be deemed consequential, punitive, indirect, special or incidental damages for any purpose of this Agreement. Other than with respect to Excluded Liabilities and Obligations, or any Losses due to any fraud, willful misconduct, intentional misrepresentation or intentional breach, in no event shall the Seller’s aggregate liability for Losses under ‎Section 8.1(a)(i) or the Buyer’s aggregate liability for Losses under ‎Section 8.1(b)(i) exceed [***].
Section 8.4Third Party Claims.  Upon providing notice to an Indemnifying Party by an Indemnified Party pursuant to ‎Section 8.2 of the commencement of any action, suit or proceeding against such Indemnified Party by a third party with respect to which such Indemnified Party intends to claim any Loss under this ‎Article 8, such Indemnifying Party shall have the right to defend such claim, at such Indemnifying Party’s expense and with counsel of its choice reasonably satisfactory to the Indemnified Party.  If the Indemnifying Party assumes the defense of such claim, the Indemnified Party shall, at the request of the Indemnifying Party, use commercially reasonable efforts to cooperate in such defense; provided, that the Indemnifying Party shall bear the Indemnified Party’s reasonable out-of-pocket costs and expenses incurred in connection with such cooperation.  So long as the Indemnifying Party is conducting the defense of such claim as provided in this ‎Section 8.4, the Indemnified Party may retain separate co-counsel at its expense and may participate in the defense of such claim, and neither the Indemnified Party nor the Indemnifying Party shall consent to the entry of any Judgment or enter into any settlement with respect to such claim without the prior written consent (which will not be unreasonably withheld, delayed, or conditioned) of the other unless such Judgment or settlement (i) provides for the payment by the Indemnifying Party of money as sole relief (if any) for the claimant (other than customary and reasonable confidentiality obligations relating to such claim, Judgment or settlement), (ii) results in the full and general release of the Indemnified Party from all liabilities arising out of, relating to or in connection with such claim and (iii) does not involve a finding or admission of any violation of any law, rule, regulation or Judgment, or the rights of any Person, and has no effect on any other claims that may be made against the Indemnified Party.  In the event the Indemnifying Party does not or ceases to conduct the defense of such claim as so provided, (a) the Indemnified Party may defend against, and consent to the entry of any Judgment or enter

25

​

into any settlement with respect to, such claim in any manner it may reasonably deem to be appropriate, (b) subject to the limitations set forth in ‎Section 8.3, the Indemnifying Party shall reimburse the Indemnified Party promptly and periodically for the reasonable out-of-pocket costs of defending against such claim, including reasonable attorneys’ fees and expenses against reasonably detailed invoices, and (c) the Indemnifying Party shall remain responsible for any Losses the Indemnified Party may suffer as a result of such claim to the full extent provided in this ‎Article 8.

Section 8.5Survival of Representations and Warranties.  The representations and warranties contained in this Agreement shall survive Closing solely for purposes of ‎Section 8.1 and shall terminate on the date that is eighteen (18) months after the Closing Date (other than any representation or warranty with respect to any Seller Fundamental Representations and any Buyer Fundamental Representations, which shall survive Closing solely for purposes of ‎Section 8.1 and shall terminate on the date that is five (5) years after termination of this Agreement). No Party hereto shall have any liability or obligation of any nature with respect to any representation or warranty after the termination thereof, unless the other party hereto shall have delivered a notice to such party, pursuant to this ‎Article 8, claiming such liability or obligation under ‎Section 8.1 prior to the date that is eighteen (18) months after the Closing Date (other than any liability or obligation of any nature with respect to any Seller Fundamental Representations and any Buyer Fundamental Representations, as to which such notice may be delivered at any time prior to the date that is five (5) years after the termination of this Agreement).
Section 8.6Exclusive Remedy.  Except as set forth in ‎Section 10.10, from and after Closing, the rights of the parties hereto pursuant to (and subject to the conditions of) this ‎Article 8 shall be the sole and exclusive remedy of the parties hereto and their respective Affiliates with respect to any claims (whether based in contract, tort or otherwise) resulting from or relating to any breach of the representations, warranties covenants and agreements made under this Agreement or any certificate, document or instrument delivered hereunder, and each party hereto hereby waives, to the fullest extent permitted under applicable law, and agrees not to assert after Closing, any other claim or action in respect of any such breach.  Notwithstanding the foregoing, claims for fraud shall not be waived or limited in any way by this ‎Article 8.

​

Article 9​
TERMINATION
Section 9.1Mutual Termination.  This Agreement may be terminated at any time by mutual written agreement of the Buyer and the Seller.
Section 9.2Automatic Termination.  Unless earlier terminated as provided in ‎Section 9.1, this Agreement shall continue in full force and effect until sixty (60) days after the full satisfaction of any amounts due under the License Agreement to the Seller and any payments in respect of the Purchased Receivables due under this Agreement to the Buyer, at which point this Agreement shall automatically terminate, except with respect to any rights that shall have accrued prior to such termination.

​

26

​

Section 9.3Survival.  Notwithstanding anything to the contrary in this ‎Article 9, the following provisions shall survive termination of this Agreement:  ‎Section 6.1 (Disclosures), ‎Section 6.2 (Payments Received in Error; Interest), ‎Article 7 (Confidentiality), ‎Article 8 (Indemnification), ‎Section 9.3 (Survival) and ‎Article 10 (Miscellaneous).  Termination of the Agreement shall not relieve any party of liability in respect of breaches under this Agreement by any party on or prior to termination.
