liability that it may have under this Section 8 except to the extent it has been materially prejudiced by such failure and; provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under this Section 8. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the Placement Agents shall have the right to employ counsel to represent the Placement Agents and their respective directors, officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Placement Agents against the Company under this Section 8 if, (i) the Company and the Placement Agents shall have so mutually agreed; (ii) the Company has failed within a reasonable time to retain counsel reasonably satisfactory to the Placement Agents; (iii) the Placement Agents and their respective directors, officers, employees and controlling persons shall have reasonably conclude, based on advice of counsel that there may be legal defenses available to them that are different from or in addition to those available to the Company; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Placement Agents or their respective directors, officers, employees or controlling persons, on the one hand, and the Company on the other hand, and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the Company. No indemnifying party shall (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding, or (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(d) If the indemnification provided for in this Section 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 8(a), 8(b) or 8(c) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company, on the one hand, and the Placement Agents, on the other, from the offering of the Stock or

(ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and the Placement Agents, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Placement Agents, on the other, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Stock in the Private Placement (before deducting expenses) received by the Company, on the one hand, and the total fees received by the Placement Agents with respect to the Stock offered and sold in the Private Placement, on the other hand, bear to the total gross proceeds from the offering of the Stock in the Private Placement. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Placement Agents, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Placement Agents agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8(d), the Placement Agents shall not be required to contribute any amount in excess of the amount by which the aggregate Placement Fee paid to the Placement Agents exceeds the amount of any damages that the Placement Agents have otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. 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. The Placement Agents’ obligations to contribute as provided in this Section 8(d) are several in proportion to their respective obligations and not joint.

(e) The Placement Agents severally confirm and the Company acknowledges and agrees that the statements in the third paragraph appearing under the caption “Private Placement” in, the Preliminary Private Placement Memorandum and the Private Placement Memorandum are correct and constitute the only information furnished in writing to the Company by or on behalf of the Placement Agents specifically for inclusion in any Private Placement Memorandum, Blue Sky Application, Marketing Materials or in any amendment or supplement thereto.

9. Termination. The obligations of the Placement Agents hereunder may be terminated by the Placement Agents by notice given to and received by the Company prior to delivery of and payment for the Stock if, prior to that time, any of the events described in Sections 7(h), 7(l) and 7(o) shall have occurred or if the Placement Agents shall decline to act as the placement agent to solicit offers in connection with the Private Placement of the Stock for any reason permitted hereunder.

10. Reimbursement of Placement Agents’ Expenses. If the Company fails to tender the Stock for delivery in connection with the Private Placement for any reason not permitted under this Agreement, the Company shall reimburse the Placement Agents for all reasonable out-of-pocket expenses (including fees and disbursements of counsel) incurred by the Placement Agents in connection with this Agreement and the proposed Private Placement, and upon demand the Company shall pay the full amount thereof to the Placement Agents.

11. Research Independence. In addition, the Company acknowledges that the Placement Agents’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that the Placement Agents’ research analysts may hold and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering that differ from the views of their respective investment banking divisions. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Placement Agents with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company by the Placement Agents’ investment banking divisions. The Company acknowledges that the Placement Agents are full service securities firms and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies which may be the subject of the transactions contemplated by this Agreement.

12. No Fiduciary Duty. The Company acknowledges and agrees that in connection with the Private Placement or any other services the Placement Agents may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Placement Agents: (i) no fiduciary or agency relationship between the Company and any other person, on the one hand, and either Placement Agent, on the other, exists; (ii) neither Placement Agent is acting as an advisor, expert or otherwise, to the Company, including, without limitation, with respect to the determination of the public offering price of the Stock, and such relationship between the Company, on the one hand, and the Placement Agents, on the other, is entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Placement Agents may have to the Company shall be limited to those duties and obligations specifically stated herein; and (iv) the Placement Agents and their affiliates may have interests that differ from those of the Company. The Company hereby waives any claims that the Company may have against the Placement Agents with respect to any breach of fiduciary duty in connection with the Private Placement.
