The Investor hereby authorizes the Escrow Agent to release such funds in accordance with the terms of the Escrow Agreement and to take such other actions as provided therein. Such funds shall be held in escrow until the Closing and delivered by the Escrow Agent on behalf of the Investor to the Company upon the satisfaction, in the sole judgment of the Placement Agents, of the Company Closing Conditions. The Placement Agents shall have no rights in or to any of the escrowed funds, unless the Placement Agents and the Escrow Agent are notified in writing by the Company in connection with the Closing that a portion of the escrowed funds shall be applied to the Placement Fee.

The Company and the Investor agree that: (i) the Escrow Agent shall be obligated only for the performance of such duties as are specifically set forth herein and may rely and shall be protected in relying or refraining from acting on any instrument reasonably believed by it to be genuine and to have been signed or presented by the proper party or parties; (ii) the Escrow Agent shall not be personally liable for any act it may do or omit to do hereunder as escrow agent while acting in good faith and in the exercise of its own good judgment, and any act done or omitted by it pursuant to the advice of its legal counsel and other experts shall be conclusive evidence of such good faith; (iii) the Escrow Agent is hereby expressly authorized to disregard any and all warnings given by any of the parties hereto or by any other person or company, excepting only orders or process of courts of law, and are hereby expressly authorized to comply with and obey orders, judgments or decrees of any court; and (iv) should any dispute arise with respect to the delivery and/or ownership or rights of possession of the escrowed funds held by the Escrow Agent hereunder, the Escrow Agent is authorized and directed to retain in its possession without liability to anyone all or any part of said funds until such dispute shall have been settled either by mutual written agreement of the parties concerned or by a final order, decree, or judgment of a court of competent jurisdiction after the time for appeal has expired and no appeal has been perfected, but the Escrow Agent shall be under no duty whatsoever to institute or defend any such proceedings. The Company and the Investor agree to indemnify and hold the Escrow Agent harmless from and against any and all losses, costs, damages, expenses and claims (including, without limitation, court costs and reasonable attorneys fees) ("Losses") arising under this Section 3.3 or otherwise with respect to the funds held in escrow pursuant hereto or arising under the Escrow Agreement, unless it is finally determined that such Losses resulted directly from the willful misconduct or gross negligence of the Escrow Agent. Anything in this Agreement to the contrary notwithstanding, in no event shall the Escrow Agent be liable for any special, indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Escrow Agent has been advised of the likelihood of such loss or damage and regardless of the form of action.

Investor shall also furnish to the Placement Agents a completed W-9 form (or, in the case of an Investor who is not a United States citizen or resident, a W-8 form), if requested.

Investor acknowledges that the Escrow Agent acts as counsel to the Placement Agents, and shall have the right to continue to represent the Placement Agents, in any action, proceeding, claim, litigation, dispute, arbitration or negotiation in connection with the Offering or otherwise, and Investor hereby consents thereto and waives any objection to the continued representation of the Placement Agents by the Escrow Agent in connection therewith based upon the services of the Escrow Agent under the Escrow Agreement, without waiving any duty or obligation the Escrow Agent may have to any other person.
