The Company hereby agrees to indemnify, protect, defend and hold harmless the Placement Agent, each director, officer and employee thereof, and each person, if any, who controls the Placement Agent within the meaning of Section 15 of the Securities Act of 1933, as amended, or Section 20 of the Securities Exchange Act of 1934, as amended (any such person being herein sometimes called an "Indemnified Party"), against all losses, claims, damages, liabilities or expenses, whether joint or several, to which any such Indemnified Party may become subject, under any statute or regulation at law or in equity or otherwise insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof) arise out of or are based upon any (a) breach of any warranty, representation or agreement of the Company set forth in this Series A Debenture Placement Agreement, or (b) untrue statement or alleged untrue statement of a material fact set forth in the Private Placement Memorandum, or any amendment or supplement thereof, or arise out of or are based upon (i) the omission or alleged omission to state therein a material fact required to be stated therein or which is necessary to make the statements made therein, in light of the circumstances in which they were made, not misleading in any material respect, and will reimburse any legal or other expenses reasonably incurred by any such Indemnified Party in connection with investigating or defending any such loss, claim, damage, liability or action. Provided, however, that such indemnity shall not extend to any Indemnified Party if the loss, claim, damage or liability is caused by the gross negligence or misconduct of the Indemnified Party. This indemnity agreement shall not be construed as a limitation on any other liability that the Company may otherwise have to any Indemnified Party, provided that in no event shall the Company be obligated for double indemnification.

(b) Procedure. An Indemnified Party shall, promptly after the receipt of notice of the commencement of any action against such Indemnified Party, in respect of which indemnification may be sought against the Company, notify the Company in writing of the commencement thereof. Failure of the Indemnified Party to give such notice will reduce the liability of the Company by the amount of damages attributable to the failure of the Indemnified Party to give such notice to the Company, but the omission to notify the Company of any such action shall not relieve the Company from any liability that it may have to such Indemnified Party otherwise than under this section. In case any such action shall be brought against an Indemnified Party and such Indemnified Party shall notify the Company of the commencement thereof, the Company may, or if so requested by such Indemnified Party shall, participate therein or assume the defense thereof, with counsel satisfactory to such Indemnified Party (it being understood that, except as hereinafter provided, the Company shall not be liable for the expenses of more than one separate counsel representing the Indemnified Parties in such action), and after notice from the Company to such Indemnified Party of an election so to assume the defense thereof, the Company will not be liable to such Indemnified Party under this Section for any legal or other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that unless and until the Company assume the defense of any such action at the request of such Indemnified Party, the Indemnified Party shall have the right to participate at its own expense in the defense of any such action. If the Company shall not have employed counsel to take charge of the defense of any such action, or if an Indemnified Party shall have reasonably concluded that there may be defenses available to it or other Indemnified Parties that are different from or additional to those available to the Company (in which cases the Company shall not have the right to direct the defense of such action on behalf of such Indemnified Party) or to other Indemnified Parties, legal and other expenses, including the expenses of separate counsel incurred by such Indemnified Party, shall be borne by the Company.

(c) Placement Agent's Agreement. The Placement Agent agrees, at its expense, to indemnify, promptly defend (by counsel reasonably satisfactory to the Company) and hold harmless the Company, and its officers, directors, employees and each person, if any, who has the power, directly or indirectly, to direct or cause the direction of the management and policies of the Company, from and against any and all losses, claims, damages, demands, liabilities, costs or expenses, including reasonable attorneys' fees and expenses, if such losses, claims, damages, demands, liabilities, costs or expenses arise out of, or are materially increased by, or would not exist but for, a breach by the Placement Agent of its duties under, or failure to abide by any of its covenants in, this Agreement.
