costs of investigation; provided, that the Indemnified Party shall have the right to employ separate counsel to represent the Indemnified Party and its Representatives who may be subject toliability arising out of any claim in respect of which indemnity may be sought by the Indemnified Party against the Indemnifying Party, but the fees and expenses of such counsel shall be for the account of and shall be paid by such Indemnified Partyunless (i) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of such counsel or (ii) in the written opinion of counsel to such Indemnified Party, representation of both parties by the same counselwould be inappropriate due to actual or potential conflicts of interest between them, it being understood, however, that the Indemnifying Party shall not, in connection with any one such claim or action or separate but substantially similar orrelated claims or actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (together with appropriate local counsel) at any timefor all Indemnified Parties.

The relative fault of the Company on the one hand and of each Designated Holder on the other shall be determined by reference to,among other things, whether any action taken, including any untrue or alleged untrue statement of a material fact, or the omission or alleged omission to state a material fact relates to information supplied by such party, and the parties’relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 

The Company and theDesignated Holders agree that it would not be just and equitable if contribution pursuant to this Section 2.9(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitableconsiderations referred to in the immediately preceding paragraph.
