(a) Promptly after the receipt by any Person seeking indemnification hereunder (an “Indemnified Party”) of a notice of any Claim by any Third Party that may be subject to indemnification hereunder (a “Third Party Claim”), such Indemnified Party shall give written notice of such Third Party Claim to the indemnifying Party (the “Indemnifying Party”) stating the nature and basis of the Third Party Claim and the amount thereof, to the extent known, along with copies of the relevant documents evidencing the Third Party Claim and the basis for indemnification sought. Failure of the Indemnified Party to give such notice shall not relieve the Indemnifying Party from liability on account of this indemnification, except if and to the extent that the Indemnifying Party is actually prejudiced thereby.

(b) The Indemnifying Party, at its own expense, shall have the right, exercisable within 30 days of receipt of notice of the Third Party Claim, to assume the defense of the Indemnified Party against the Third Party Claim so long as (i) the Indemnifying Party proceeds in good faith and in a timely manner and (ii) such Third Party Claim involves (and continues to involve) solely monetary damages.

(c) So long as the Indemnifying Party has assumed the defense of the Third Party Claim in accordance with Section 9.3(b), (i) the Indemnified Party may retain separate co-counsel at its sole cost and expense and participate in the defense of the Third Party Claim, it being understood that the Indemnifying Party shall pay all costs and expenses of counsel for the Indemnified Party (A) for all periods prior to such time as the Indemnifying Party has notified the Indemnified Party that it has assumed the defense of such Third Party Claim and (B) if there is a conflict of interest between the Indemnifying Party and the Indemnified Party, (ii) the Indemnified Party shall not file any papers or consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld or delayed), and (iii) the Indemnifying Party shall not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld or delayed).

(d) The Parties shall use commercially reasonable efforts to minimize Losses from Third Party Claims and shall act in good faith and in a timely manner in responding to, defending against, settling or otherwise dealing with Third Party Claims. The Parties shall also cooperate in any such defense and give each other reasonable access to all information relevant thereto. Whether or not the Indemnifying Party shall have assumed the defense of a Third Party Claim, the Indemnifying Party shall not be obligated to indemnify the Indemnified Party hereunder for any settlement entered into without the Indemnifying Party’s prior written consent, which consent shall not unreasonably withheld or delayed. Notwithstanding the foregoing, the Indemnified Party shall have the sole and exclusive right to settle any Third Party Claim, on such terms and conditions as it deems reasonably appropriate, to the extent such claim involves equitable or other non-monetary relief.

9.4 Fault of Parties. THE INDEMNIFICATION PROVIDED FOR IN THIS ARTICLE IX SHALL BE APPLICABLE WHETHER OR NOT THE CLAIMS IN QUESTION AROSE FROM THE SOLE, CONCURRENT ACTIVE OR PASSIVE NEGLIGENCE OF THE PARTIES OR ANY THIRD PARTY AND REGARDLESS OF WHO MAY BE AT FAULT OR OTHERWISE RESPONSIBLE UNDER ANY OTHER CONTRACT, OR ANY STATUTE, RULE, OR THEORY OF LAW, INCLUDING, BUT NOT LIMITED TO, THEORIES OF STRICT LIABILITY BUT EXCLUDING GROSS NEGLIGENCE AND WILLFUL MISCONDUCT OF A PARTY. THE PARTIES ACKNOWLEDGE THAT THE FOREGOING INDEMNITIES TOGETHER WITH THIS STATEMENT COMPLIES WITH THE EXPRESS NEGLIGENCE RULE AND IS CONSPICUOUS.
