The notice to the indemnifying party shall specify, if known, the amount or an estimate

of the amount of the liability arising therefrom. The Indemnified Party shall not settle or compromise any such claim without the prior written consent of the indemnifying party unless suit shall have been instituted against the Indemnified Party and the indemnifying party shall have failed, within fifteen (15) days after notice of institution of the suit, to take control of such suit as provided in Section 10(d) below.

(d) Defense of Actions. In connection with any claim giving rise to indemnity hereunder resulting from or arising out of any claim or legal proceeding by a person who is not a party to this Agreement, the indemnifying party, at its sole cost and expense, may, upon written notice to the Indemnified Party, assume the defense of such claim or legal proceeding, to the extent that the indemnifying party admits in writing its liability to the Indemnified Party with respect to all material elements thereof. If the indemnifying party assumes the defense of any such claim or legal proceeding, the obligations of the indemnifying party hereunder as to such claim or legal proceeding shall be limited to taking all steps necessary in the defense or settlement thereof and to holding the Indemnified Party harmless from and against any losses, damages, expenses, or liability caused by or arising out of any settlement approved by the indemnifying party or any judgment in connection with such claim or legal proceeding. Each Indemnified Party agrees that it will cooperate with the indemnifying party in the defense of any such action, the defense of which is assumed by the indemnifying party. Except with the consent of the Indemnified Party, the indemnifying party shall not consent to the entry of any judgment arising from any such claim or legal proceeding which, in each case, does not include as an unconditional term thereof the delivering by the claimant or the plaintiff to the Indemnified Party of a release from all liability in respect thereof, unless the indemnifying party has actually paid to the Indemnified Party the full amount of such judgment or settlement. If the indemnifying party does not assume the defense of any claim or litigation, any Indemnified Party may defend against such claim or litigation in such manner as it may deem appropriate, including, but not limited to, settling such claim or litigation, after giving notice of the same to the indemnifying party, on such terms as the Indemnified Party may deem appropriate. The indemnifying party will promptly reimburse the Indemnified Party by payment of cash or delivery to the Indemnified Party of a certified or official bank check in the amount of the indemnification liability.
