Notwithstanding the foregoing, the failure of any Indemnitee or other Person to give notice as provided in this Section 8.4(a) shall not relieve the related Indemnifying Party of its obligations under this Article VIII, except to the extent that such Indemnifying Party is actually prejudiced by such failure to give notice.

(b) An Indemnifying Party may elect to defend (and, unless the Indemnifying Party has specified any reservations or exceptions, to seek to settle or compromise), at such Indemnifying Party’s own expense and by such Indemnifying Party’s own counsel, any Third Party Claim for which indemnification is available under this Article VIII. Within thirty (30) days after the receipt of notice from an Indemnitee in accordance with Section 8.4(a) (or sooner, if the nature of such Third Party Claim so requires), the Indemnifying Party shall notify the Indemnitee of its election whether the Indemnifying Party will assume responsibility for defending such Third Party Claim, which election

shall specify any reservations or exceptions. After notice from an Indemnifying Party to an Indemnitee of its election to assume the defense of a Third Party Claim, such Indemnitee shall have the right to employ separate counsel and to participate in (but not control) the defense, compromise or settlement thereof, but the fees and expenses of such counsel shall be the expense of such Indemnitee except as set forth in the next sentence. In the event that the Indemnifying Party has elected to assume the defense of a Third Party Claim for which indemnification is available under this Article VIII but has specified, and continues to assert, any reservations or exceptions in such notice, then, in any such case, the reasonable fees and expenses of one separate counsel for all Indemnitees shall be borne by the Indemnifying Party.

(c) If an Indemnifying Party elects not to assume responsibility for defending a Third Party Claim for which indemnification is available under this Article VIII, or fails to notify an Indemnitee of its election as provided in Section 8.4(b), such Indemnitee may defend such Third Party Claim at the cost and expense (including allocated costs of in-house counsel and other personnel) of the Indemnifying Party.

(d) Unless the Indemnifying Party has failed to assume the defense of the Third Party Claim for which indemnification is available under this Article VIII in accordance with the terms of this Agreement, no Indemnitee may settle or compromise such Third Party Claim without the consent of the Indemnifying Party.

(e) No Indemnifying Party shall consent to entry of any judgment or enter into any settlement of the Third Party Claim without the consent of an Indemnitee if the effect thereof is to permit any injunction, declaratory judgment, other order or other nonmonetary relief to be entered, directly or indirectly, against such Indemnitee.

(f) In the event of payment by or on behalf of any Indemnifying Party to any Indemnitee in connection with any Third Party Claim under this Article VIII, such Indemnifying Party shall be subrogated to and shall stand in the place of such Indemnitee as to any events or circumstances in respect of which such Indemnitee may have any right, defense or claim relating to such Third Party Claim against any claimant or plaintiff asserting such Third Party Claim or against any other person. Such Indemnitee shall cooperate with such Indemnifying Party in a reasonable manner, and at the cost and expense (including allocated costs of in-house counsel and other personnel) of such Indemnifying Party, in prosecuting any subrogated right, defense or claim. In the event of an Action in which the Indemnifying Party is not a named defendant, if either the Indemnitee or Indemnifying Party shall so request, the parties shall endeavor to substitute the Indemnifying Party for the named defendant, if at all practicable. If such substitution or addition cannot be achieved for any reason or is not requested, the named defendant shall allow the Indemnifying Party to manage the Action as set forth in this Section 8.4 and the Indemnifying Party shall fully indemnify the named defendant against all costs of defending the Action (including court costs, sanctions imposed by a court, attorneys’ fees, experts’ fees and all other external expenses, and the allocated costs of in-house counsel and other personnel), the costs of any judgment or settlement, and the costs of any interest or penalties relating to any judgment or settlement.

SECTION 8.5 Mitigation of Damages. The parties each agree to attempt to mitigate, and to cause each of their respective Affiliates to attempt to mitigate, any Losses that such party may suffer as a consequence of any matter giving rise to a right to indemnification under this Article VIII by taking all actions which a reasonable person would undertake to minimize or alleviate the amount of Losses and the consequences thereof, as if such person would be required to suffer the entire amount of such Losses and the consequences thereof by itself, without recourse to any remedy against another person, including pursuant to any right of indemnification hereunder.
