EXHIBIT B

Indemnification Provisions

Capitalized terms used in this Exhibit shall have the meanings assigned to such terms in the Agreement to which this Exhibit is attached.

The Company agrees to indemnify and hold harmless the Financial Advisor from and against any and all losses, claims, damages, obligations, penalties, judgments, awards, liabilities, costs, expenses and disbursements, and any and all actions, suits, proceedings and investigations in respect thereof and any and all legal and other costs, expenses and disbursements in giving testimony or furnishing documents in response to a subpoena or otherwise (including, without limitation, the costs, expenses and disbursements, as and when incurred, of investigating, preparing, pursing or defending any such action, suit, proceeding or investigation (whether or not in connection with litigation in which the Financial Advisor is a party)) (collectively, “Losses”), directly or indirectly, caused by, relating to, based upon, arising out of, or in connection with, the Financial Advisor’s acting for the Company, including, without limitation, any act or omission by the Financial Advisor in connection with its acceptance of or the performance or non-performance of its obligations under the Agreement between the Company and the Financial Advisor to which these indemnification provisions are attached and form a part (the “Agreement”), any breach by the Company of any representation, warranty, covenant or agreement contained in the Agreement (or in any instrument, document or agreement relating thereto, including any Agency Agreement), or the enforcement by the Financial Advisor of its rights under the Agreement or these indemnification provisions, except to the extent that any such Losses are found in a final judgment by a court of competent jurisdiction (not subject to further appeal) to have resulted primarily and directly from the gross negligence or willful misconduct of the Financial Advisor seeking indemnification hereunder. The Company also agrees that the Financial Advisor shall not have any liability (whether direct or indirect, in contract or tort or otherwise) to the Company for or in connection with the engagement of the Financial Advisor by the Company or for any other reason, except to the extent that any such liability is found in a final judgment by a court of competent jurisdiction (not subject to further appeal) to have resulted primarily and directly from the Financial Advisor’s gross negligence or willful misconduct.

If any action, suit, proceeding or investigation is commenced, as to which the Financial Advisor proposes to demand indemnification, it shall notify the Company with reasonable promptness; provided, however, that any failure by the Financial Advisor to notify the Company shall not relieve the Company from its obligations hereunder. The Financial Advisor shall have the right to retain counsel of its own choice to represent it, and the fees, expenses and disbursements of such counsel shall be borne by the Company. Any such counsel shall, to the extent consistent with its professional responsibilities, cooperate with the Company and any counsel designated by the Company. The Company shall be liable for any settlement of any claim against the Financial Advisor made with the Company’s written consent. The Company shall not, without the prior written consent of the Financial Advisor, settle or compromise any claim, or permit a default or consent to the entry of any judgment in respect thereof, unless such settlement, compromise or consent (i) includes, as an unconditional term thereof, the giving by the claimant to the Financial Advisor of an unconditional release from all liability in respect of such claim, and (ii) does not contain any factual or legal admission by or with respect to the Financial Advisor or an adverse statement with respect to the character, professionalism, expertise or reputation of the Financial Advisor or any action or inaction of the Financial Advisor.

In order to provide for just and equitable contribution, if a claim for indemnification pursuant to these indemnification provisions is made but it is found in a final judgment by a court of competent jurisdiction (not subject to further appeal) that such indemnification may not be enforced in such case, even though the express provisions hereof provide for indemnification in such case, then the Company shall contribute to the Losses to which the Financial Advisor may be subject (i) in accordance with the relative benefits received by the Company and its stockholders, subsidiaries and affiliates, on the one hand, and the Financial Advisor, on the other hand, and (ii) if (and only if) the allocation provided in clause (i) of this sentence is not permitted by applicable law, in such proportion as to reflect not only the relative benefits, but also the relative fault of the Company, on the one hand, and the Financial Advisor, on the other hand, in connection with the statements, acts or omissions which resulted in such Losses as well as any relevant equitable considerations. No person found liable for a fraudulent misrepresentation shall be entitled to contribution from any person who is not also found liable for fraudulent misrepresentation. The relative benefits received (or anticipated to be received) by the Company and its stockholders, subsidiaries and affiliates shall be deemed to be equal to the aggregate consideration payable or receivable by such parties in connection with the transaction or transactions to which the Agreement relates relative to the amount of fees actually received by the Financial Advisor in connection with such transaction or transactions. Notwithstanding the foregoing, in no event shall the amount contributed by the Financial Advisor exceed the amount of fees previously received by the Financial Advisor pursuant to the Agreement.

Neither termination nor completion of the Agreement shall affect these Indemnification Provisions which shall remain operative and in full force and effect. The Indemnification Provisions shall be binding upon the Company and its successors and assigns and shall inure to the benefit of the Financial Advisor and its respective successors, assigns, heirs and personal representatives.
