WHEREAS, the Company has entered into an Underwriting Agreement, dated [_____], 2017 (“Underwriting Agreement”), with EarlyBirdCapital, Inc. (the “Representative”) acting as representative of the several underwriters (collectively, the “Underwriters”), pursuant to which, among other matters, the Underwriters have agreed to purchase 10,000,000 units (“Units”) of the Company, plus an additional 1,500,000 Units if the Representative exercises the over-allotment option in full. Each Unit consists of one share of the Company’s common stock, par value $.0001 per share (“Common Stock”), one right to receive one-tenth of one share of Common Stock upon the consummation by the Company of a merger, share exchange, asset acquisition, stock purchase, recapitalization, reorganization or other similar business combination with one or more businesses or entities (“Business Combination”), and one half of one Warrant, each whole Warrant to purchase one share of Common Stock, in the Company’s initial public offering (the “IPO”), all as more fully described in the Company’s final Prospectus, dated [_____], 2017 (“Prospectus”) comprising part of the Company’s Registration Statement on Form S-1 (File No. 333-_________) under the Securities Act of 1933, as amended (“Registration Statement”), declared effective on [_____], 2017 (“Effective Date”).

WHEREAS, the Sponsor has agreed as a condition of the sale of the Units to deposit its 2,875,000 shares of Common Stock of the Company in escrow as hereinafter provided.

WHEREAS, the Company and the Sponsor desire that the Escrow Agent accept the shares, in escrow, to be held and disbursed as hereinafter provided.

IT IS AGREED:

1.             Appointment of Escrow Agent. The Company and the Sponsor hereby appoint the Escrow Agent to act in accordance with and subject to the terms of this Agreement and the Escrow Agent hereby accepts such appointment and agrees to act in accordance with and subject to such terms.

2.             Deposit of Shares. On or before the Effective Date, the Sponsor shall have delivered to the Escrow Agent a certificate representing such Sponsor’s shares, to be held and disbursed subject to the terms and conditions of this Agreement. The Sponsor acknowledges that the certificate representing such Sponsor’s shares is legended to reflect the deposit of such shares under this Agreement.

3.             Disbursement of the Escrow Shares.

3.1       If the Underwriters do not exercise in full their over-allotment option to purchase up to an additional 1,500,000 Units of the Company within 45 days of the date of the Prospectus (as described in the Underwriting Agreement), the Sponsor agrees that the Escrow Agent shall return to the Company for cancellation, at no cost, a number of shares determined by multiplying 375,000 by a fraction, (i) the numerator of which is 1,500,000 minus the number of shares of Common Stock, if any, purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which is 1,500,000. The Company shall promptly provide notice to the Escrow Agent of the expiration or termination of the Underwriters’ over-allotment option and the number of Units, if any, purchased by the Underwriters in connection with their exercise thereof.

3.2       Except as otherwise set forth herein, the Escrow Agent shall hold the shares remaining after any cancellation required pursuant to Section 3.1 above (such remaining shares to be referred to herein as the “Escrow Shares”) until (i) with respect to 50% of the Escrow Shares, on the earlier of (x) one year after the date of the consummation of the Company’s initial Business Combination and (y) the date on which the closing price of the Company’s Common Stock equals or exceeds $12.50 per share (as adjusted for stock splits, stock dividends, reorganizations and recapitalizations) for any 20 trading days within any 30-trading day period commencing after the Company’s initial Business Combination and (ii) with respect to the remaining 50% of the Escrow Shares, one year after the date of the consummation of an initial Business Combination (the “Escrow Period”). The Company shall promptly provide notice of the consummation of a Business Combination to the Escrow Agent. Upon completion of the Escrow Period, the Escrow Agent shall disburse such amount of each Initial Stockholder’s Escrow Shares (and any applicable share power) to such Initial Stockholder; provided, however, that if the Escrow Agent is notified by the Company pursuant to Section 6.7 hereof that the Company is being liquidated because it failed to consummate a Business Combination within the time period specified in the Prospectus, then the Escrow Agent shall promptly destroy the certificates representing the Escrow Shares; provided further, however, that if, within one year after the Company consummates a Business Combination, the Company (or the surviving entity) subsequently consummates a liquidation, merger, stock exchange or other similar transaction which results in all of the stockholders of such entity having the right to exchange their shares of Common Stock for cash, securities or other property, then the Escrow Agent will, upon receipt of a notice executed by the Chairman of the Board, Chief Executive Officer or other authorized officer of the Company, in form reasonably acceptable to the Escrow Agent, certifying that such transaction is then being consummated or such conditions have been achieved, as applicable, release the Escrow Shares to the Initial Stockholders. The Escrow Agent shall have no further duties hereunder after the disbursement or destruction of the Escrow Shares in accordance with this Section 3.

4.            Rights of Initial Stockholder in Escrow Shares.

4.1       Voting Rights as a Stockholder.

4.2       Dividends and Other Distributions in Respect of the Escrow Shares. For as long as any shares are held in escrow pursuant to this Agreement, all dividends payable in cash with respect to the Escrow Shares shall be paid to the Initial Stockholders, but all dividends payable in stock or other non-cash property (“Non-Cash Dividends”) shall be delivered to the Escrow Agent to hold in accordance with the terms hereof. As used herein, the term “Escrow Shares” shall be deemed to include the Non-Cash Dividends distributed thereon, if any.

4.3       Restrictions on Transfer. During the Escrow Period, the only permitted transfers of the Escrow Shares will be (i) to the Initial Stockholders’ or the Company’s officers, directors, employees, consultants or their affiliates, (ii) to an Initial Stockholders’ officers, directors, employees or members upon the Initial Stockholders’ liquidation, in each case if the Initial Stockholder is an entity, (iii) by bona fide gift to a member of the Initial Stockholders’ immediate family or to a trust, the beneficiary of which is the Initial Stockholder or a member of the Initial Stockholders’ immediate family for estate planning purposes, (iv) by virtue of the laws of descent and distribution upon death, (v) pursuant to a qualified domestic relations order, (vi) to the Company for no value for cancellation in connection with the consummation of a Business Combination or (vii) in connection with the consummation of an initial Business Combination, by private sales of the Escrow Shares at prices no greater than the price at which the Escrow Shares were originally purchased; provided, however, that except for clause (vi) or with the Company’s prior written consent, such permissive transfers may be implemented only upon the respective transferee’s written agreement to be bound by the terms and conditions of this Agreement and of the Insider Letter signed by the Sponsor transferring the shares.

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 other parties hereto 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 Escrow Shares or it may deposit the Escrow Shares with the clerk of any appropriate court or it may retain the Escrow Shares 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 Escrow Shares are to be disbursed and delivered.

5.6       Discharge of Escrow Agent.
