In the case of a claim originating from a Person other than the Indemnified Party (a “Third Party Claim”), the Indemnifying Party shall have the right to elect, by written notice delivered to the Indemnified Party within thirty (30) days of receipt by the Indemnifying Party of the notice from the Indemnified Party in respect of the Third Party Claim, at the sole expense, cost and risk of the Indemnifying Party to participate in or assume control of the defence of the Third Party Claim and to pursue such defence in good faith by appropriate actions or proceedings promptly taken or instituted and diligently pursued, including, without limitation, to employ and engage attorneys of its own choice reasonably acceptable to the Indemnified Party to defend, compromise or settle such claim, provided that the Indemnifying Party shall pay all reasonable out-of-pocket expenses incurred by the Indemnified Party as a result of such participation or assumption, provided, further, that any compromise or settlement shall be made only with the written consent of the Indemnified Party, such consent not to be unreasonably withheld.

(d)

If the Indemnifying Party does not elect to assume control of the Third Party Claim, or if having so elected to assume control, it thereafter fails to proceed with the defence or settlement of such Third Party Claim in good faith and with reasonable diligence, then the Indemnified Party shall be entitled to assume control of the Third Party Claim at the Indemnifying Party’s sole expense, cost and risk. An Indemnified Party agreeing to assume control of a claim shall use commercially reasonable efforts to deal with the claim reasonably diligently and in a manner consistent with the manner in which the Indemnified Party would have acted if there had been no indemnity. In such case, the Indemnifying Party shall be kept reasonably informed of the progress of any defence, compromise or settlement (and shall be entitled to participate in at its expense, but not assume control of, such action).

(e)

The Indemnifying Party or the Indemnified Party who does not have control of the Third Party Claim shall cooperate with the other of them in the defence thereof (at the cost and expense of the Indemnifying Party), such cooperation to include the provision of records and information within its control that are relevant to the Third Party Claim and making available its employees and servants (and those of its affiliates) as are appropriate and reasonably necessary and relevant to the Third Party Claim.
