(c) Loss Indemnity Procedure. (i) Upon learning of the commencement of a Covered Action or the actual receipt by the party claiming a right of indemnification of information relating to the purported existence of facts or circumstances which could result in the commencement of a Purchaser or Seller Covered Action or other incurrence of a Purchaser or Seller Loss, the party claiming the right of indemnification (the "Indemnified Party") shall promptly, but no later than fifteen (15) days after learning of such commencement or receipt, give notice thereof, with reasonable specificity of the facts as then known, to the party having the indemnification obligation (the "Indemnifying Party"); provided, however, failure to give timely notice shall not release the Indemnifying Party of its obligations hereunder except if, and only to the extent that, the Indemnifying Party suffers actual prejudice as a proximate result of such failure. (ii) The Indemnifying Party shall have the right to assume the defense of any such Covered Action only by giving written notice (the "Assumption Notice") to the Indemnified Party within 20 days after notice given pursuant to Section 9(c)(i) above, which Assumption Notice shall state that (A) it agrees that the claimant is entitled to indemnification hereunder; and (B) it agrees or they agree to assume the defense thereof in the name and on behalf of the Indemnified Party with counsel reasonably satisfactory to the Indemnified Party, in either event at the sole cost and expense of the Indemnifying Party; provided, however: A. all such costs and expenses of the foregoing counsel, if not paid by the Indemnifying Party and instead paid by the Indemnified Party shall be Losses indemnifiable by the Indemnifying Party under Section 9(a) or (b), as the case may be, B. the Indemnified Party, notwithstanding the timely delivery of an Assumption Notice, may participate in such Covered Action through counsel separately selected and paid for by the Indemnified Party, and 24 C. if no Assumption Notice complying with subclauses (A) and (B) above is timely given, or despite the giving of the Assumption Notice the defendants in any Purchaser Covered Action or Seller Covered Action, as the case may be, include both the Indemnified Party and the Indemnifying Party, and the Indemnified Party shall have reasonably concluded that there may be legal defenses available to it which are different from or additional to those available to the Indemnifying Party, or if there is a conflict of interest which would prevent counsel for the Indemnifying Party from also representing the Indemnified Party, then the Indemnified Party in each of the foregoing cases shall have the right to select one separate counsel to conduct the defense of such action on its behalf, and all such costs and expenses shall be paid by the Indemnifying Party and, if paid by the Indemnified Party, shall be Purchaser Losses or Seller Losses indemnifiable by the Indemnifying Party under Subsection 9(a) or (b), as the case may be. The Indemnified Party may take such action with respect to a Purchaser or Seller Covered Action as it may deem appropriate to protect against further damage or default, including obtaining an extension of time to answer the complaint or other pleading or filing an answer thereto.

(e) Duration of Indemnification. Liability for indemnification hereunder shall expire as provided in Section 9(h) below unless the Purchaser gives written notice prior to such date of expiration to the Seller of a Purchaser Loss or a Purchaser Covered Action (setting forth in reasonable detail the specific facts and circumstances then known and pertaining thereto). In any of such events, such liability shall survive until such Purchaser Loss or Purchaser Covered Action is finally determined and any indemnification payment due with respect thereto or with respect to a Purchaser Loss is made. (f) Limitations. 25 (i) Notwithstanding anything to the contrary contained in this Section 9, (A) the Sellers shall not be obligated to pay in the aggregate any amounts in respect of Purchaser Losses in excess of $3,500,000 (the "Indemnification Cap") and (B) the Purchaser shall not be obligated to pay in the aggregate any amounts in respect of Seller Losses in excess of the Indemnification Cap.
