Any such defence shall be through legal counsel acceptable to the Indemnified Party and no admission of liability shall be made by the Company or the Indemnified Party without, in each case, the prior written consent of all the parties hereto, such consent not to be unreasonably withheld. An Indemnified Party shall have the right to employ separate counsel in any such suit and participate in the defence thereof but the fees and expenses of such counsel shall be at the expense of the Indemnified Party unless: (i) the Company fails to assume the defence of such suit on behalf of the Indemnified Party within a reasonable period of receiving notice of such suit, provided that the expiration of such period shall be deemed to occur on the second clear business day immediately preceding the date by which the Indemnified Party is required by law (in the absence of agreement to the contrary) to take action (such as the filing of an appearance or its equivalent) in connection with defending such suit; (ii) the employment of such counsel has been authorized by the Company; or (iii) the named parties to any such suit include both the Indemnified Party and the Company and the Indemnified Party shall have been advised by counsel that there may be one or more defences available to the Indemnified Party which are different from or in addition to those available to the Company (in each of which cases the Company shall not have the right to assume the defence of such suit on behalf of the Indemnified Party but shall be liable to pay the reasonable fees and expenses of counsel for the Indemnified Party).

Notwithstanding the foregoing, a person guilty of fraudulent misrepresentation, bad faith or gross negligence shall not be entitled to contribution from any other party. Any party entitled to contribution will, promptly after receiving notice of commencement of any claim, action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this Section, notify such party or parties for whom contribution may be sought. In no case shall such party from whom contribution may be sought be liable to contribute pursuant to this Agreement unless such notice shall have been provided, but the omission to so' notify such party shall not relieve the party from whom contribution may be sought from any other obligation it may have otherwise than under this Section. The right to contribution provided in this Section shall be in addition to and not in derogation of any other right to contribution which the any party may have by statute or otherwise by law.
