In the event that the Indemnified Party and the Indemnifying Part do not execute a memorandum as contemplated above within [*] business days of receipt by the Indemnified Party of the Objection Notice, then the Buyer Indemnified Party may commence an action to resolve such dispute and enforce its rights with respect thereto in any court available therefor (such action, a “Litigated Dispute”).

If the Indemnifying Part fails or refuses to assume control of the defense of such Third-Party Claim, the Indemnified Party shall have the right, but no obligation, to defend against such Third-Party Claim, including settling such Third-Party Claim after giving notice to Seller, in each case in such manner and on such terms as the Indemnified Party may deem appropriate. Neither the Indemnified Party’s failure to perform any obligation under this Section 8(d), nor any act or omission of the Indemnified Party in the defense or settlement of any Third-Party Claim shall relieve Seller of its obligations under this Section 8, including with respect to any Losses, except to the extent that Seller can demonstrate that it has been materially prejudiced as a result thereof.
