In any such action, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the sole expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) in the reasonable judgment of such indemnified party representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, in which case the fees and expenses of one separate counsel (together with any required local counsel) shall be at the sole expense of the indemnifying party. It is understood that the indemnifying party shall not, other than as provided in the preceding sentence, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) at any time for all such indemnified parties, and that all such fees and expenses shall be reimbursed as they are incurred. The indemnifying party shall not be liable for any settlement of any claim or action effected without its written consent, which consent shall not be unreasonably withheld or delayed, but if settled with such consent, or if there be a final judgment for the plaintiff, the indemnifying party shall indemnify and hold harmless such indemnified parties from and against any loss or liability (to the extent stated above) by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened claim or action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability arising out of such proceeding and imposes no obligations on such indemnified party other than the payment of monetary damages (which damages will be paid by the indemnifying party hereunder).

(iv) If the indemnification provided for in this Section ‎8(i) shall for any reason be unavailable (other than in accordance with its terms), including without limitation instances where (i) a party otherwise entitled to indemnification is judicially determined (by entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced, notwithstanding the fact that this Section ‎8(i) provides for indemnification, or (ii) contribution under the Securities Act may be required on the part of any party hereto, for which indemnification is provided under this Section ‎8(i), then the indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by the indemnified party as a result of any Damages that would otherwise be indemnifiable hereunder, in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and the indemnified party on the other. The relative fault shall be determined by reference to, among other things, whether the 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 the indemnifying party or the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. Notwithstanding anything in this Section ‎8(i)(iv) to the contrary, in no event shall the Investor’s liability pursuant to this Section ‎8(i)(iv), when combined with the amounts paid or payable by the Investor pursuant to Section ‎8(i)(ii), in connection with any given registration, exceed the net proceeds received by the Investor in connection with the offering of its Shares under such registration. In addition, neither the Investor or any Affiliate thereof shall be required to pay any amount under this Section ‎8(i)(iv) unless such Person or entity would have been required to pay an amount pursuant to Section ‎8(i)(ii) if it had been applicable in accordance with its terms. The parties to this Agreement agree that it would not be just and equitable if contribution pursuant to this Section ‎8(i)(iv) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. If indemnification is available under this Section ‎8(i), the indemnifying parties shall indemnify each indemnified party to the full extent provided in Sections ‎8(i)(i) and ‎8(i)(ii) without regard to the relative fault of said indemnifying parties or indemnified party.

(v) The obligations of the parties under this Section ‎8(i) shall be in addition to any liability which any party may otherwise have to any other party.

(vi) The rights and obligations of the Company and the Investor under this Section ‎8(i) shall survive the Closing or any termination of this Agreement, and shall control over any inconsistent or conflicting provisions in any underwriting agreement.
