Exhibit 10.4


 


STOCK ESCROW AGREEMENT


 


This STOCK ESCROW AGREEMENT,
dated as of [__________], 2015 (this “Agreement”), is made by and among Jensyn Acquisition Corp., a Delaware corporation
(“Company”), Jensyn Capital LLC, a Delaware limited liability company, Jeffrey J. Raymond, Rebecca Irish, Joseph Raymond
and Peter Underwood (the “Initial Stockholders” and each an “Initial Stockholder”), and CONTINENTAL STOCK
TRANSFER & TRUST COMPANY, a New York corporation (“Escrow Agent”).


 


WHEREAS, the Company
has entered into an Underwriting Agreement, dated as of [__________], 2015 (the “Underwriting Agreement”), with Chardan
Capital Markets, LLC (“CCM”) acting as representative of the several underwriters (collectively, the “Underwriters”),
pursuant to which, among other matters, the Underwriters have agreed to purchase 5,000,000 units (“Units”) of the Company,
plus an additional 750,000 Units if the Underwriters exercise their over-allotment option in full. Each Unit consists of one share
of common stock of the Company, par value $0.0001 per share (“Common Stock”), one right (a “Right”) to
receive one-tenth of one share of Common Stock upon the Company’s initial business combination and one warrant (a “Warrant”)
to purchase one-half of one share of Common Stock, all as more fully described in the Company’s final Prospectus, dated [__________],
2015 (the “Prospectus”), comprising part of the Company’s Registration Statement on Form S-1 (File No. 333-______)
under the Securities Act of 1933, as amended (the “Registration Statement”), declared effective on [_________], 2015
(the “Effective Date”);


 


WHEREAS, the Initial
Stockholders have agreed as a condition of the sale of the Units to deposit the aggregate 1,437,500 shares of Common Stock held
by the Initial Stockholders prior to the Company’s initial public offering as set forth opposite their respective names in
Exhibit A attached hereto (the “Escrow Shares”) in escrow as hereinafter provided; and


 


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


 


IT IS AGREED:


 


		1.	Appointment of Escrow Agent. The Company and each of the Initial Stockholders 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 Escrow Shares. On or before the Effective Date, each of the Initial Stockholders
shall deliver to the Escrow Agent certificates representing the Escrow Shares, together with applicable stock powers, to be held
and disbursed subject to the terms and conditions of this Agreement. Each of the Initial Stockholder acknowledges that the certificate
representing the Escrow Shares is legended to reflect the deposit of such Escrow Shares under this Agreement.



 


		3.	Disbursement of the Escrow Shares.



 


		3.1.	The Escrow Agent shall hold the Escrow Shares during the period (the “Escrow Period”)
commencing on the date hereof and (i) for 50% of the Escrow Shares, ending on the earlier of (x) one year after the date of the
consummation of the Company’s initial business combination (as described in the Registration Statement, hereinafter a “Business
Combination”), (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 Business Combination and (z) the date of consummation of a Sale Transaction, and
(ii) for the remaining 50% of the Escrow Shares, ending on the earlier of (x) one year after the date of the consummation of a
Business Combination and (y) the date of consummation of a Sale Transaction. For purposes hereof, a “Sale Transaction”
means a liquidation, merger, stock exchange or other similar transaction subsequent to the Company’s initial Business Combination
which results in all of the stockholders of the Company or such other entity surviving the Business Combination having the right
to exchange their shares of Common Stock for cash, securities or other property. The Company shall promptly provide notice of the
consummation of a Business Combination or a Sale Transaction to the Escrow Agent. Upon completion of the Escrow Period, the Escrow
Agent shall disburse the applicable amount of each of the Initial Stockholder’s Escrow Shares (and any applicable stock power)
to such Initial Stockholder. In addition, if the Escrow Agent is notified by the Company pursuant to Section 6.7 hereof that the
Company is being liquidated at any time during the Escrow Period, then the Escrow Agent shall destroy the certificates representing
the Escrow Shares. The Escrow Agent shall have no further duties hereunder after the disbursement of the Escrow Shares in accordance
with this Section 3.



 




    	 



    	 



    

 


		3.2.	Notwithstanding Section 3.1, if the Underwriters do not exercise in full their over-allotment option
to purchase an additional 750,000 Units of the Company within 45 days of the date of the Prospectus (as described in the Underwriting
Agreement), each of the Initial Stockholders agrees that the Escrow Agent shall return to the Company for cancellation, at no cost,
the number of Escrow Shares held by such holder determined by multiplying 46,875 by a fraction, (i) the numerator of which is 750,000
minus the number of shares of Common Stock purchased by the Underwriters upon the exercise of their over-allotment option, and
(ii) the denominator of which is 750,000. 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.



 


		4.	Rights of Initial Stockholders in Escrow Shares.



 


		4.1.	Voting Rights as a Stockholder. Subject to the terms of the Insider Letter described in
Section 4.4 hereof and except as herein provided, each of the Initial Stockholders shall retain all of such Initial Stockholders’
rights as a stockholder of the Company during the Escrow Period, including, without limitation, the right to vote such shares.



 


		4.2.	Dividends and Other Distributions in Respect of the Escrow Shares. During the Escrow Period,
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 Company’s officers, directors, advisors and employees, (ii) as a distribution to partners,
members or stockholders of an Initial Stockholder upon the liquidation and dissolution of the Initial Stockholder, (iii) by bona
fide gift to a member of an Initial Stockholder’s immediate family or to a trust, the beneficiary of which is such Initial
Stockholder or a member of such Initial Stockholder’s 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) by private sales at prices
no greater than the price at which the Escrow Shares were originally purchased or (vii) to the Company for cancellation as set
forth in Section 3.2 hereof or in connection with the consummation of a Business Combination, in each case, except for clause (vii),
on the condition that such 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 (as defined below) signed by the Initial Stockholder transferring
the Escrow Shares.



 


		4.4.	Insider Letters. Each of the Initial Stockholders has executed a letter agreement with the
Company, dated as indicated on Exhibit A hereto, and the form of which is filed as an exhibit to the Registration Statement (the
“Insider Letter”), respecting the rights and obligations of such Initial Stockholder in certain events, including but
not limited to the liquidation of the Company.

		5.	Concerning the Escrow Agent.



 


		5.1.	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, 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.



 


		5.2.	Indemnification. The Escrow Agent shall be indemnified and held harmless by the Company
from and against any expenses, including counsel fees and disbursements, or loss suffered by the Escrow Agent in connection with
any action, suit or other proceeding involving any claim which in any way, directly or indirectly, arises out of or relates to
this Agreement, the services of the Escrow Agent hereunder, or the Escrow Shares held by it hereunder, other than expenses or losses
arising from the gross negligence or willful misconduct of the Escrow Agent. 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. The provisions of this Section 5.2 shall survive in the event the Escrow Agent resigns or is
discharged pursuant to Sections 5.5 or 5.6 below.



 


		5.3.	Compensation. The Escrow Agent shall be entitled to compensation from the Company for all
services rendered by it hereunder as set forth in Exhibit B. The Escrow Agent shall also be entitled to reimbursement from the
Company for all reasonable 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.



 


		5.4.	Further Assurances. From time to time on and after the date hereof, the Company and each
of 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.



 


		5.5.	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 Escrow Shares held hereunder. If no new escrow agent is so appointed within the 60-day period following
the giving of such notice of resignation, the Escrow Agent may deposit the Escrow Shares with any court it reasonably deems appropriate.



 


		5.6.	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
5.5.



 


		5.7.	Liability. Notwithstanding anything herein to the contrary, the Escrow Agent shall not be
relieved from liability hereunder for its own gross negligence or its own willful misconduct.



 


		5.8.	Waiver. The Escrow Agent hereby waives any right of set-off or any other right, title, interest
or claim of any kind (“Claim”) in, or to any distribution of, the Trust Account (as defined in that certain Investment
Management Trust Agreement, dated as of the date hereof, by and between the Company and the Escrow Agent as trustee thereunder)
and hereby agrees not to seek recourse, reimbursement, payment or satisfaction for any Claim against the Trust Account for any
reason whatsoever.
