Exhibit 10.5

PRIVATE UNITS PURCHASE AGREEMENT

THIS PRIVATE UNITS PURCHASE AGREEMENT, dated as of March 2, 106 (as it may from time to time be amended and including all exhibits referenced herein, this “Agreement”), is entered into by and between Jensyn Acquisition Corp., a Delaware corporation (the “Company”), and Jensyn Capital, LLC, a Delaware limited liability company (the “Purchaser”).

The Company intends to consummate an initial public offering (the “Public Offering”) of the Company’s units (the “Public Units”), each Public Unit consisting of one share of the Company’s common stock, par value $0.0001 per share (a “Share”), one right to receive one-tenth (1/10) of a Share automatically on the consummation of an initial business combination and one warrant (a “Public Warrant”). Each Public Warrant entitles the holder thereof to purchase one-half of one Share. The Company will not issue fractional Shares. As a result, holders of Public Warrants must exercise Public Warrants in multiples of two Public Warrants, at a price of $11.50 per full Share, subject to adjustment as described in the prospectus associated with the Public Offering, to validly exercise Public Warrants. The Purchaser has agreed to purchase an aggregate of 275,000 units (or 310,100 units if the underwriters’ over-allotment option in connection with the Public Offering is exercised in full) (the “Private Units”), each Private Unit consisting of one share of the Company’s common stock (a “Private Share”), one right to receive one-tenth (1/10) of a Share automatically on the consummation of an initial business combination (a “Private Right”) and one warrant (a “Private Warrant” and, together with the Private Units, Private Shares, Private Rights and the Shares underlying the Private Warrants and Private Rights, the “Securities”). The Private Units are identical to the Public Units, except that the Private Units may not be transferred, assigned or sold (except to certain permitted transferees, provided the transferees agree to certain terms and restrictions, as described herein) until the completion of the Company’s initial business combination. On the Closing Date, the Purchase Price (as defined below) for the Private Units will be deposited in the trust account that will hold the proceeds of the Public Offering (the “Trust Account”).

NOW THEREFORE, in consideration of the mutual promises contained in this Agreement and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties to this Agreement hereby, intending legally to be bound, agree as follows:

Neither the Company nor, to its knowledge, any of its affiliates, members, officers, directors or beneficial shareholders of 20% or more of its outstanding securities, has experienced a disqualifying event as enumerated pursuant to Rule 506(d) of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”).

E. Governmental Consents. No permit, consent, approval or authorization of, or declaration to or filing with, any governmental authority is required in connection with the execution, delivery and performance by the Company of this Agreement or the consummation by the Company of any other transactions contemplated hereby.

Section 3. Representations and Warranties of the Purchaser. As a material inducement to the Company to enter into this Agreement and issue and sell the Private Units to the Purchaser, the Purchaser hereby represents and warrants to the Company (which representations and warranties shall survive the Closing Date) that:

A. Organization and Requisite Authority. The Purchaser possesses all requisite power and authority necessary to carry out the transactions contemplated by this Agreement.

B. Authorization; No Breach.

(i) This Agreement constitutes a valid and binding obligation of the Purchaser, enforceable in accordance with its terms, subject to bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other laws of general applicability relating to or affecting creditors’ rights and to general equitable principles (whether considered in a proceeding in equity or law).

(ii) The execution and delivery by the Purchaser of this Agreement and the fulfillment of and compliance with the terms hereof by the Purchaser does not and shall not as of the Closing Date conflict with or result in a breach by the Purchaser of the terms, conditions or provisions of any agreement, instrument, order, judgment or decree to which the Purchaser is subject.

C. Investment Representations.

(i) The Purchaser is acquiring the Securities for the Purchaser’s own account, for investment purposes only and not with a view towards, or for resale in connection with, any public sale or distribution thereof.

(ii) The Purchaser is an “accredited investor” as such term is defined in Rule 501(a) of Regulation D under the Securities Act, and the Purchaser has not experienced a disqualifying event as enumerated pursuant to Rule 506(d) of Regulation D under the Securities Act.

(iii) The Purchaser understands that the Securities are being offered and will be sold to it in reliance on specific exemptions from the registration requirements of the United States federal and state securities laws and that the Company is relying upon the truth and accuracy of, and the Purchaser’s compliance with, the representations and warranties of the Purchaser set forth herein in order to determine the availability of such exemptions and the eligibility of the Purchaser to acquire such Securities.

(iv) The Purchaser did not decide to enter into this Agreement as a result of any general solicitation or general advertising within the meaning of Rule 502(c) under the Securities Act.

(v) The Purchaser has been furnished with all materials relating to the business, finances and operations of the Company and materials relating to the offer and sale of the Securities which have been requested by the Purchaser. The Purchaser has been afforded the opportunity to ask questions of the executive officers and directors of the Company. The Purchaser understands that its investment in the Securities involves a high degree of risk and it has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to the acquisition of the Securities.

3

(vi) The Purchaser understands that no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Securities or the fairness or suitability of the investment in the Securities by the Purchaser nor have such authorities passed upon or endorsed the merits of the offering of the Securities.

(vii) The Purchaser understands that: (a) the Securities have not been and are not being registered under the Securities Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred unless (1) subsequently registered thereunder or (2) sold in reliance on an exemption therefrom; and (b) except as specifically set forth in the Registration Rights Agreement, neither the Company nor any other person is under any obligation to register the Securities under the Securities Act or any state securities laws or to comply with the terms and conditions of any exemption thereunder. In this regard, the Purchaser understands that the Securities and Exchange Commission (the “SEC”) has taken the position that promoters or affiliates of a blank check company and their transferees, both before and after a business combination, are deemed to be “underwriters” under the Securities Act when reselling the securities of a blank check company. Based on that position, Rule 144 adopted pursuant to the Securities Act would not be available for resale transactions of the Securities, despite technical compliance with the requirements of such Rule, and the Securities can be resold only through a registered offering or in reliance upon another exemption from the registration requirements of the Securities Act.

(viii) The Purchaser has such knowledge and experience in financial and business matters, knows of the high degree of risk associated with investments in the securities of companies in the development stage such as the Company, is capable of evaluating the merits and risks of an investment in the Securities and is able to bear the economic risk of an investment in the Securities in the amount contemplated hereunder for an indefinite period of time. The Purchaser has adequate means of providing for its current financial needs and contingencies and will have no current or anticipated future needs for liquidity which would be jeopardized by the investment in the Securities. The Purchaser can afford a complete loss of its investment in the Securities.
