Notwithstanding any other provision of this Agreement, no claim for indemnification by either party based on a breach of a representation or warranty made in this Agreement, unless such breach rises to the level of fraud, in which case these provisions shall not apply, pursuant to Sections 8.2(a) or 8.3(a), as applicable, or a breach of any covenant or agreement made in this Agreement pursuant to Sections 8.2(b)or 8.3(b), as applicable, against the other party may be made after the first anniversary of the Closing Date. Claims for indemnification may be brought pursuant to Sections 8.2(c), 8.2(d), 8.3(c) or 8.3(d), as applicable, against the other party at any time during the applicable statute of limitations.

8.5. Matters Involving Third Parties, including Third Party Claims. If any third party notifies either party (“Indemnified Party”) with respect to any matter which may give rise to a claim for indemnification against the other party (the “Indemnifying Party”) under this Article VIII, the Indemnified Party shall notify the Indemnifying Party promptly in writing; provided, however, that no delay on the part of the Indemnified Party in notifying the Indemnifying Party shall relieve the Indemnifying Party from any liability or obligation unless (and then solely to the extent) the Indemnifying Party is damaged by the delay. In the event the Indemnifying Party notifies the Indemnified Party within fifteen (15) days after the Indemnified Party has given notice of the matter that the Indemnifying Party is assuming its defense, (a) the Indemnifying Party shall defend the Indemnified Party against the matter with counsel of the Indemnifying Party’s choice reasonably satisfactory to the Indemnified Party, (b) the Indemnified Party shall cooperate in the defense of such claim and may retain separate co-counsel at its sole cost and expense, (c) the Indemnified Party shall not consent to the entry of any judgment or enter into any settlement with respect to the matter without the prior written consent of the Indemnifying Party (not to be unreasonably withheld or delayed), and (d) the Indemnifying Party shall not consent to the entry of any judgment with respect to the matter, or enter into any settlement which does not include a provision whereby the plaintiff or claimant in the matter releases the Indemnified Party from all liability with respect to the claim, without the prior written consent of the Indemnified Party (not to be unreasonably withheld or delayed). In the event the Indemnifying Party fails to notify the Indemnified Party within 15 days after the Indemnified Party has given notice of the matter that the Indemnifying Party is assuming its defense, the Indemnified Party may defend against, or enter into any settlement with respect to, the matter in any manner it may deem appropriate.

8.6. Matters Involving the Parties. In the event that the Indemnified Party asserts a claim under this Article VIII (excluding claims covered by Section 8.5) against the Indemnifying Party, the Indemnified Party shall give written notice to the Indemnifying Party specifying, in reasonable detail, the basis for the assertion of the claim and the amount of the claim asserted. Such assertion of liability shall be deemed accepted by such Indemnifying Party and the amount of such claim shall be deemed a valid claim, conclusive and binding on the Indemnifying Party, unless, within twenty (20) days after the Indemnified Party gives written notice to the Indemnifying Party of such claim, the Indemnifying Party gives written notice to the Indemnified Party contesting the basis for, or the amount of, such claim. If such notice is given by the Indemnifying Party, then the parties shall use commercially reasonable efforts to reach agreement with respect to such claim. If no such agreement is reached, the parties may pursue their respective rights and remedies to the full extent of the law, subject to the terms of this Agreement.

8.7. Mitigation. The Indemnified Party shall take all reasonable steps to mitigate all Damages, including availing itself as reasonably directed by the Indemnifying Party of any defenses, limitations, rights of contribution, claims against third parties and other rights at law, and shall provide such evidence and documentation of the nature and extent of any Damages as may be reasonably requested by the Indemnifying Party. Each party shall use commercially reasonable efforts in addressing any Damages that may provide the basis for an indemnifiable claim (that is, each party shall respond to such liability in the same manner that it would respond to such liability in the absence of the indemnification provided for in this Agreement). Any request for indemnification of specific costs shall include invoices and supporting documents containing reasonably detailed information about the costs and/or damages for which indemnification is being sought.

8.8. Exclusive Remedy. The parties acknowledge that the indemnification provided in this Article VIII shall be the sole and exclusive remedy after the Closing Date for monetary damages available to the parties to this Agreement for breach of any of the terms, conditions, representations or warranties contained herein; provided, however, this exclusive remedy for damages does not preclude a party from (a) bringing an action for specific performance or other available equitable remedy for a breach of a covenant or agreement contained in this Agreement, or (b) pursuing remedies under applicable law for fraud.
