Re: Initial Public Offering

Gentlemen:

This letter is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) entered into by and between Constellation Alpha Capital Corp., a British Virgin Islands Company (the “Company”), and Xxxxx and Company, LLC. as Representative (the “Representative”) of the several Underwriters named in Schedule A thereto (the “Underwriters”), relating to an underwritten initial public offering (the “IPO”) of the Company’s units (the “Units”), each comprised of one ordinary share, no par value, of the Company (the “Ordinary Shares”), one warrant (the “Warrant”) to purchase one-half of one Ordinary Share and one right to receive one-tenth (1/10) of one Ordinary Share upon the consummation of the Company’s initial business combination (the “Right”). Certain capitalized terms used herein are defined in paragraph 17 hereof.

In order to induce the Company and the Underwriters to enter into the Underwriting Agreement and to proceed with the IPO, and in recognition of the benefit that such IPO will confer upon the undersigned as a shareholder or officer or director of the Company, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned xxxxxx agrees with the Company as follows:

1.    If the Company solicits approval of its shareholders of a Business Combination (as defined below), the undersigned will vote all Ordinary Shares beneficially owned by him, her or it, whether acquired before, in or after the IPO, or whether such Ordinary Shares are underlying the Private Units, in favor of such Business Combination.

2.     (a) In the event that the Company fails to consummate a Business Combination within the time period set forth in the Company’s Amended and Restated Memorandum and Articles of Association, as the same may be amended from time to time, the undersigned shall take all reasonable steps to (i) cause the Trust Fund to be liquidated and distributed to the holders of IPO Shares and (ii) cause the Company to liquidate as soon as reasonably practicable.

(b) The undersigned hereby waives any and all right, title, interest or claim of any kind (“Claim”) in, or, with respect to his, her or its Insider Shares or Private Units, to any distribution of, the Trust Fund. The undersigned hereby waives any Claim the undersigned may have in the future as a result of, or arising out of, any contracts or agreements with the Company and will not seek recourse against the Trust Fund for any reason whatsoever. The undersigned acknowledges and agrees that there will be no distribution from the Trust Fund with respect to any Rights or Warrants, which will terminate on the Company’s liquidation.

(c) In the event of the liquidation of the Trust Fund, Centripetal, LLC (“Sponsor”) agrees to indemnify and hold harmless the Company against any and all loss, liability, claims, damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably incurred in investigating, preparing or defending against any litigation, whether pending or threatened, or any claim whatsoever) which the Company may become subject as a result of any claim by any vendor or other person who is owed money by the Company for services rendered or products sold to or contracted for the Company, or by any target business with which the Company has discussed entering into a transaction agreement, but only to the extent necessary to ensure that such loss, liability, claim, damage or expense does not reduce the amount of funds in the Trust Fund to below $10.00 per IPO Share; provided that such indemnity shall not apply if such vendor or other person executes a waiver of any and all rights to seek access to the Trust Account and except as to claims under the Company’s indemnity of the underwriters of the IPO against certain liabilities.

3.     (a) The Sponsor agrees that it shall not Transfer any Insider Shares: (x) with respect to 50% of its Insider Shares, until the earlier of (i) one year after the date of the consummation of the Business Combination or (ii) the date on which the closing price of the Ordinary Shares 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 Business Combination and (y) with respect to the remaining 50% of its Insider Shares, one year after the date of the consummation of the Business Combination, or earlier, in either case, if, subsequent to the Business Combination, the Company consummates a subsequent liquidation, merger, stock exchange or other similar transaction which results in all of the Company’s shareholders having the right to exchange their Ordinary Shares for cash, securities or other property.

(b) The Sponsor agrees that it shall not effectuate any Transfer of securities issued or issuable upon the exercise of the Private Units or their underlying securities until after the completion of the Business Combination.

4.     [Intentionally Omitted].

5.     In order to minimize potential conflicts of interest which may arise from multiple affiliations, the undersigned directors and officers of the Company agree to present to the Company for its consideration, prior to presentation to any other person or entity, any suitable opportunity to acquire a target business, until the earlier of the consummation by the Company of a Business Combination or the liquidation of the Company, subject to any pre-existing fiduciary and contractual obligations the undersigned directors and officers might have.

6.    The undersigned acknowledges and agrees that prior to entering into a Business Combination with a target business that is affiliated with any Insiders of the Company or their affiliates, such transaction must be approved by a majority of the Company’s disinterested independent directors and the Company must obtain an opinion from an independent investment banking firm or independent accounting firm that such Business Combination is fair to the Company’s unaffiliated shareholders from a financial point of view.

7.     Neither the undersigned, any member of the family of the undersigned, nor any affiliate of the undersigned will be entitled to receive and will not accept any compensation or other cash payment for services rendered prior to, or in order to effectuate, the consummation of the Business Combination; provided that the Company shall be allowed to (i) repay working capital loans made by the undersigned or its affiliates to the Company in cash upon consummation of the Business Combination or, at the undersigned’s discretion, with respect to up to an aggregate of $1,500,000 of working capital loans from all lenders, by converting such loans into Private Units at a price of $10.00 per Private Unit, as more fully described in the Registration Statement, (ii) repay a non-interest bearing advances in an aggregate amount of [_____] made to the Company by the Sponsor to cover the IPO expenses, (iii) pay $10,000 per month to an affiliate of the Chief Executive Officer and Chairman of the Company for office space and related services, and (iv) reimburse the undersigned and any affiliate of the undersigned for their out-of-pocket expenses incurred in connection with identifying, investigating and consummating a Business Combination.

8.     Neither the undersigned, any member of the family of the undersigned, nor any affiliate of the undersigned will be entitled to receive or accept a finder’s fee or any other compensation in the event the undersigned, any member of the family of the undersigned or any affiliate of the undersigned originates a Business Combination.

9.    The undersigned officers and directors agree to be the officers and directors of the Company until the earlier of the consummation by the Company of a Business Combination, the liquidation of the Company or such officer or director is officially replaced by the Company’s board of directors. The undersigned officers’ and directors’ biographical information previously furnished to the Company and the Representative is true and accurate in all material respects, does not omit any material information with respect to the officers’ and directors’ biography and contains all of the information required to be disclosed pursuant to Item 401 of Regulation S-K, promulgated under the Securities Act of 1933, as amended (the “Securities Act”).
