(a) Good Faith Reliance. The Escrow Agent shall not be liable for any action taken or omitted by it in good faith and in the exercise of its own best judgment, and may rely conclusively and shall be protected in acting upon any order, notice, demand, certificate, opinion or advice of counsel (including counsel chosen by the Escrow Agent), statement, instrument,

2

report or other paper or document (not only as to its due execution and the validity and effectiveness of its provisions, but also as to the truth and acceptability of any information therein contained) which is believed by the Escrow Agent to be genuine and to be signed or presented by the proper person or persons. The Escrow Agent shall not be bound by any notice or demand, or any waiver, modification, termination or rescission of this Agreement unless evidenced by a writing delivered to the Escrow Agent signed by the proper party or parties and, if the duties or rights of the Escrow Agent are affected, unless it shall have given its prior written consent thereto.

(b) Indemnification. The Escrow Agent shall be indemnified and held harmless, jointly and severally, by the Company and the Initial Stockholders other than Bulldog Investors and White Sand Investor Group, LP (such indemnifying parties, the “Indemnifying Stockholders”) from and against any losses, claims, damages, liabilities or expenses, including counsel fees and disbursements, suffered by the Escrow Agent in connection with any action, suit or other proceeding involving any claim which in any way, directly or indirectly, relates to or arises out of this Agreement, the performance by the Escrow Agent of services under this Agreement or with respect to the Sponsors’ Purchase Price, except to the extent any losses, claims, damages or liabilities are found in a final judgment by a court of competent jurisdiction to have resulted from the Escrow Agent’s willful misconduct or gross negligence. Promptly after the receipt by the Escrow Agent of notice of any demand or claim or the commencement of any action, suit or proceeding, the Escrow Agent shall notify the Company and the Indemnifying Stockholders in writing. In the event of the receipt of such notice, the Escrow Agent, in its sole discretion, may commence an action in the nature of interpleader in an appropriate court to determine ownership or disposition of the Sponsors’ Purchase Price or it may deposit the Sponsors’ Purchase Price with the clerk of any appropriate court or it may retain the Sponsors’ Purchase Price pending receipt of a final, non-appealable order of a court having jurisdiction over all of the parties hereto directing to whom and under what circumstances the Sponsors’ Purchase Price is to be disbursed and delivered. The Company and the Initial Stockholders agree that the Escrow Agent shall have no liability (whether direct or indirect, in contract, tort or otherwise) to the Company or the Initial Stockholders under this Agreement related to or arising out of the performance by the Escrow Agent of services under this Agreement or with respect to the Sponsors’ Purchase Price, except to the extent any losses, claims, damages or liabilities are found in a final judgment by a court of competent jurisdiction to have resulted from the Escrow Agent’s willful misconduct or gross negligence. The provisions of this Section 4(b) shall survive in the event the Escrow Agent resigns or is discharged pursuant to Sections 4(e) or 4(f) below.

(c) Compensation. The Escrow Agent shall be entitled to reimbursement from the Company for all expenses paid or incurred by it in the administration of its duties hereunder including, but not limited to, all counsel, advisors’ and agents’ fees and disbursements and all taxes or other governmental charges.

(d) Further Assurances. If the underwriters’ over-allotment option for the IPO has not been exercised during the 45-day period following the consummation of the IPO, then, no later than 9:00 a.m. New York City time on the 46th day after the date of the consummation of the IPO, the Chairman of the Board, Chief Executive Officer or other authorized officer of the Company shall provide written notice to the Escrow Agent certifying that the underwriters’ over-allotment option for the IPO has not been exercised within the required timeframe. From time to time on and after the date hereof, the Company and the Initial Stockholders shall deliver or cause

to be delivered to the Escrow Agent such further documents and instruments and shall do or cause to be done such further acts as the Escrow Agent shall reasonably request to carry out more effectively the provisions and purposes of this Agreement, to evidence compliance herewith or to assure itself that it is protected in acting hereunder.

(e) Resignation. The Escrow Agent may resign at any time and be discharged from its duties as escrow agent hereunder by its giving the other parties hereto written notice and such resignation shall become effective as hereinafter provided. Such resignation shall become effective at such time that the Escrow Agent shall turn over to a successor escrow agent appointed by the Company, the Sponsors’ Purchase Price held hereunder. If no new escrow agent is so appointed within the sixty (60) day period following the giving of such notice of resignation, the Escrow Agent may deposit the Sponsors’ Purchase Price with any court it reasonably deems appropriate.

(f) Discharge of Escrow Agent. The Escrow Agent shall resign and be discharged from its duties as escrow agent hereunder if so requested in writing at any time by the other parties hereto, jointly; provided, however, that such resignation shall become effective only upon acceptance of appointment by a successor escrow agent as provided in Section 4(e).
