Engagement: The Company hereby engages HCW as its exclusive agent to facilitate the exercise (“Warrant Exercise”) by the holders thereof (“Holders”) of outstanding common stock purchase warrants of the Company with expiry dates of November 21, 2014, November 7, 2018, April 16, 2019 and May 1, 2019. HCW shall engage in discussions with the Holders regarding the terms of such exercise and facilitate the closing of the Warrant Exercise.

Term; Exclusivity: This exclusive engagement will commence on the date hereof and terminate on September 30, 2014. (“Term”), provided that the Company can immediately terminate this engagement if the Warrant Exercise is not completed on or before September 1, 2014.

Best Efforts: It is understood that HCW’s involvement in a Warrant Exercise is strictly on a reasonable best efforts basis and that the consummation of a Warrant Exercise will be subject to, among other things, market conditions. It is understood that HCW’s assistance in a Warrant Exercise will be subject to the satisfactory completion of such investigation and inquiry into the affairs of the Company as HCW deems appropriate under the circumstances (such investigation hereinafter to be referred to as “Due Diligence”) and to the receipt of all internal approvals of HCW in connection with the Warrant Exercise. HCW shall have the right in its sole discretion to terminate this Agreement if the outcome of the Due Diligence is not satisfactory to HCW or if approval of its internal committees is not obtained.

Fees: As compensation for the services to be rendered by HCW hereunder, the Company will pay HCW and amount equal to 10% of the gross proceeds received by the Company in connection with the Warrant Exercise (“Transaction Fee”), which fee shall be immediately payable upon receive by the Company of any such proceeds. HCW may elect to retain the services of an escrow agent, at the expense and with the written consent of the Company, to facilitate to the Warrant Exercise and pursuant to which the Transaction Fee shall be paid directly to HCW. The Company also agrees to reimburse HCW $10,000 for its legal fees and expenses (the “Expense Reimbursement”) (provided, however, that such expense cap in no way limits or impairs the indemnification and contribution provisions of this Agreement), provided that no Expense Reimbursement shall be payable by the Company to HCW if the Warrant Exercise results in gross proceeds to the Company of less than $500,000. The Transaction Fee and the Expense Reimbursement shall be the only fees and expenses payable by the Company to HCW in connection with the Warrant Exercise (provided, however, that this provision in no way limits or impairs the indemnification and contribution provisions of this Agreement).

Indemnification:

To the extent permitted by law, the Company will indemnify HCW and its affiliates, stockholders, directors, officers, employees and controlling persons (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) against all losses, claims, damages, expenses and liabilities, as the same are incurred (including the reasonable fees and expenses of counsel), relating to or arising out of its activities hereunder or pursuant to this engagement letter, except to the extent that any losses, claims, damages, expenses or liabilities (or actions in respect thereof) are found in a final judgment (not subject to appeal) by a court of law to have resulted primarily and directly from HCW’s willful misconduct or gross negligence in performing the services described herein.

Promptly after receipt by HCW of notice of any claim or the commencement of any action or proceeding with respect to which HCW is entitled to indemnity hereunder, HCW will notify the Company in writing of such claim or of the commencement of such action or proceeding, and the Company will assume the defense of such action or proceeding and will employ counsel reasonably satisfactory to HCW and will pay the fees and expenses of such counsel. Notwithstanding the preceding sentence, HCW will be entitled to employ counsel separate from counsel for the Company and from any other party in such action if counsel for HCW reasonably determines that it would be inappropriate under the applicable rules of professional responsibility for the same counsel to represent both the Company and HCW. In such event, the reasonable fees and disbursements of no more than one such separate counsel will be paid by the Company, in addition to local counsel. The Company will have the exclusive right to settle the claim or proceeding provided that the Company will not settle any such claim, action or proceeding without the prior written consent of HCW, which will not be unreasonably withheld.

The Company agrees to notify HCW promptly of the assertion against it or any other person of any claim or the commencement of any action or proceeding relating to a transaction contemplated by this engagement letter.

If for any reason the foregoing indemnity is unavailable to HCW or insufficient to hold HCW harmless, then the Company shall contribute to the amount paid or payable by HCW as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect not only the relative benefits received by the Company on the one hand and HCW on the other, but also the relative fault of the Company on the one hand and HCW on the other that resulted in such losses, claims, damages or liabilities, as well as any relevant equitable considerations. The amounts paid or payable by a party in respect of losses, claims, damages and liabilities referred to above shall be deemed to include any legal or other fees and expenses incurred in defending any litigation, proceeding or other action or claim. Notwithstanding the provisions hereof, HCW’s share of the liability hereunder shall not be in excess of the amount of fees actually received, or to be received, by HCW under this engagement letter (excluding any amounts received as reimbursement of expenses incurred by HCW).

These indemnification provisions shall remain in full force and effect whether or not the transaction contemplated by this engagement letter is completed and shall survive the termination of this engagement letter, and shall be in addition to any liability that the Company might otherwise have to any indemnified party under this engagement letter or otherwise.
