Option.

 

THIS CERTIFIES THAT, in consideration of
$[100.00] duly paid by or on behalf of [Chardan Capital Markets, LLC] (“Holder”), as registered owner
of this Purchase Option, to Jensyn Acquisition Corp. (“Company”), Holder is entitled, at any time or
from time to time upon the later of the consummation of a Business Combination or [________], 2016 (“Commencement Date”),
and at or before 5:00 p.m., New York City local time, on the earlier of the liquidation of the Company’s Trust Fund (as described
in the Company’s registration statement (“Registration Statement”) pursuant to which Units are
offered for sale to the public (“Offering”)) in the event the Company has not completed a Business Combination
within the required time periods and [________], 2021, five years from the effective date (“Effective Date”)
of the Registration Statement (“Expiration Date”), but not thereafter, to subscribe for, purchase and
receive, in whole or in part, up to [Four Hundred Thousand (400,000)] units (“Units”) of the Company,
each Unit consisting of one share of common stock of the Company, par value $0.0001 per share (“Common Stock”),
one right to receive one-tenth (1/10) of a share of Common Stock automatically on the consummation of an initial Business Combination
(the “Rights”), and one warrant (“Warrant(s)”). Each Warrant is the same as
the whole warrant included in the Units being registered for sale to the public by way of the Registration Statement (“Public
Warrants”). If the Expiration Date is a day on which banking institutions are authorized by law to close, then this
Purchase Option may be exercised on the next succeeding day which is not such a day in accordance with the terms herein. During
the period ending on the Expiration Date, the Company agrees not to take any action that would terminate the Purchase Option. This
Purchase Option is initially exercisable at $12.00 per Unit so purchased; provided, however, that upon the occurrence of any of
the events specified in Section 6 hereof, the rights granted by this Purchase Option, including the exercise price per Unit and
the number of Units (and Common Stock, Rights and Warrants) to be received upon such exercise, shall be adjusted as therein specified.
The term “Exercise Price” shall mean the initial exercise price or the adjusted exercise price, depending on the context.

 

    	 	 	 

     

    

 

2.           Exercise.

 

2.1         Exercise
Form. In order to exercise this Purchase Option, the exercise form attached hereto must be duly executed and completed and
delivered to the Company, together with this Purchase Option and payment of the Exercise Price for the Units being purchased payable
in cash or by certified check or official bank check. If the subscription rights represented hereby shall not be exercised at or
before 5:00 p.m., New York City local time, on the Expiration Date this Purchase Option shall become and be void without further
force or effect, and all rights represented hereby shall cease and expire.

 

2.2         Legend.
Each certificate for the securities purchased under this Purchase Option shall bear a legend as follows unless such securities
have been registered under the Securities Act of 1933, as amended (“Act”):

 

“The securities represented by this certificate
have not been registered under the Securities Act of 1933, as amended (“Act”) or applicable state law. The securities
may not be offered for sale, sold or otherwise transferred except pursuant to an effective registration statement under the Act,
or pursuant to an exemption from registration under the Act and applicable state law.”

 

    	 	2	 

     

    

 

2.3         Cashless
Exercise.

 

2.3.1         Determination
of Amount. In lieu of the payment of the Exercise Price multiplied by the number of Units for which this Purchase Option is
exercisable (and in lieu of being entitled to receive Common Stock, Rights and Warrants) in the manner required by Section 2.1,
the Holder shall have the right (but not the obligation) to convert any exercisable but unexercised portion of this Purchase Option
into Units (“Cashless Exercise Right”) as follows: upon exercise of the Cashless Exercise Right, the
Company shall deliver to the Holder (without payment by the Holder of any of the Exercise Price in cash) that number of Units (or
that number of shares of Common Stock, Rights and Warrants comprising that number of Units) equal to the quotient obtained by dividing
(x) the “Value” (as defined below) of the portion of the Purchase Option being converted by (y) the Current Market
Value (as defined below). The “Value” of the portion of the Purchase Option being converted shall equal
the remainder derived from subtracting (a) (i) the Exercise Price multiplied by (ii) the number of Units underlying the portion
of this Purchase Option being converted from (b) the Current Market Value of a Unit multiplied by the number of Units underlying
the portion of the Purchase Option being converted. As used herein, the term “Current Market Value” per
Unit at any date means: (A) in the event that Public Warrants are not still trading, the remainder derived from subtracting (x)
the exercise price of the Warrants multiplied by the number of shares of Common Stock issuable upon exercise of the Warrants underlying
one Unit from (y) (i) the Current Market Price of the Common Stock multiplied by (ii) the number of shares of Common Stock underlying
one Unit, which shall include the Common Stock underlying the Rights and Warrants included in such Unit; and (B) in the event that
the Common Stock and Public Warrants underlying the Units are still trading, the Current Market Price of the Common Stock plus
the product of (x) the Current Market Price of the Public Warrants, and (y) the number of shares of Common Stock underlying the
Warrants included in one Unit. The “Current Market Price” shall mean (i) if the Common Stock (or Public Warrants, as
the case may be) is listed on a national securities exchange or quoted on the OTC Bulletin Board or the OTC Markets Group Inc.
(or successor markets), the last sale price of the Common Stock (or Public Warrants) in the principal trading market for the Common
Stock as reported by the applicable market on the last trading day preceding the date in question; and (ii) if the fair market
value of the Common Stock cannot be determined pursuant to clause (A) or (B) above, such price as the Board of Directors of the
Company shall determine, in good faith. In the event the Public Warrants have expired and are no longer exercisable, no “Value”
shall be attributed to the Warrants underlying this Purchase Option.

 

2.3.1         Mechanics
of Cashless Exercise. The Cashless Exercise Right may be exercised by the Holder on any business day on or after the Commencement
Date and not later than the Expiration Date by delivering the Purchase Option with the duly executed exercise form attached hereto
with the cashless exercise section completed to the Company, exercising the Cashless Exercise Right and specifying the total number
of Units the Holder will purchase pursuant to such Cashless Exercise Right.

 

2.4         No Obligation to Net Cash Settle.
Notwithstanding anything to the contrary contained in this Purchase Option, in no event will the Company be required to net cash
settle the exercise of the Purchase Option or the Rights or Warrants underlying the Purchase Option. The holder of the Purchase
Option and the Rights and Warrants underlying the Purchase Option will not be entitled to exercise the Purchase Option or the Rights
or Warrants underlying such Purchase Option unless it exercises such Purchase Option pursuant to the Cashless Exercise Right or
a registration statement is effective, or an exemption from the registration requirements is available at such time and, if the
holder is not able to exercise the Purchase Option or underlying Rights or Warrants, the Purchase Option and/or the underlying
Rights or Warrants, as applicable, will expire worthless.

 

    	 	3	 

     

    

 

3.           Transfer.

 

3.1         General
Restrictions. The registered Holder of this Purchase Option, by its acceptance hereof, agrees that it will not sell, transfer,
assign, pledge or hypothecate this Purchase Option (or the Common Stock, Rights and Warrants underlying this Purchase Option),
or cause the Purchase Option (or the Common Stock, Rights and Warrants underlying this Purchase Option) to be the subject of any
hedging, short sale, derivative, put, or call transaction that would result in the effective economic disposition of the Purchase
Option by any person, for a period of 180 days (pursuant to Rule 5110(g)(1) of the Conduct Rules of FINRA) following the Effective
Date to anyone other than (i) Chardan or an underwriter or selected dealer in connection with the Offering, or (ii) a
bona fide officer or partner of Chardan or of any such underwriter or selected dealer. On and after the first anniversary of the
Effective Date, transfers to others may be made subject to compliance with or exemptions from applicable securities laws. In order
to make any permitted assignment, the Holder must deliver to the Company the assignment form attached hereto duly executed and
completed, together with the Purchase Option and payment of all transfer taxes, if any, payable in connection therewith. The Company
shall within five business days transfer this Purchase Option on the books of the Company and shall execute and deliver a new Purchase
Option or Purchase Options of like tenor to the appropriate assignee(s) expressly evidencing the right to purchase the aggregate
number of Units purchasable hereunder or such portion of such number as shall be contemplated by any such assignment.

 

3.2         Restrictions
Imposed by the Act. The securities evidenced by this Purchase Option shall not be transferred unless and until (i) the
Company has received the opinion of counsel for the Holder that the securities may be transferred pursuant to an exemption from
registration under the Act and applicable state securities laws, the availability of which is established to the reasonable satisfaction
of the Company (the Company hereby agreeing that the opinion of Giordano, Halleran & Ciesla, P.C. shall be deemed satisfactory
evidence of the availability of an exemption), or (ii) a registration statement or a post-effective amendment to the Registration
Statement relating to such securities has been filed by the Company and declared effective by the Securities and Exchange Commission
(the “Commission”) and compliance with applicable state securities law has been established.

 

4.           New
Purchase Options to be Issued.

 

4.1         Partial
Exercise or Transfer. Subject to the restrictions in Section 3 hereof, this Purchase Option may be exercised or assigned in
whole or in part. In the event of the exercise or assignment hereof in part only, upon surrender of this Purchase Option for cancellation,
together with the duly executed exercise or assignment form and funds sufficient to pay any Exercise Price and/or transfer tax,
the Company shall cause to be delivered to the Holder without charge a new Purchase Option of like tenor to this Purchase Option
in the name of the Holder evidencing the right of the Holder to purchase the number of Units purchasable hereunder as to which
this Purchase Option has not been exercised or assigned.

 

4.2         Lost
Certificate. Upon receipt by the Company of evidence satisfactory to it of the loss, theft, destruction or mutilation of this
Purchase Option and of reasonably satisfactory indemnification or the posting of a bond, the Company shall execute and deliver
a new Purchase Option of like tenor and date. Any such new Purchase Option executed and delivered as a result of such loss, theft,
mutilation or destruction shall constitute a substitute contractual obligation on the part of the Company.

5.           Registration
Rights.

 

5.1         Demand
Registration.

 

5.1.1         Grant
of Right. The Company, upon written demand (“Initial Demand Notice”) of the Holder(s) of at least
51% of the Purchase Options and/or the underlying Units and/or the underlying securities (“Majority Holders”),
agrees to use its best efforts to register (the “Demand Registration”) under the Act on one occasion,
all or any portion of the (i) Purchase Options requested by the Majority Holders in the Initial Demand Notice and all of the securities
underlying such Purchase Options, including the Units, Common Stock, Rights, the Warrants and the Common Stock underlying the Rights
and Warrants and (ii) the units issued to the Holder prior to or concurrently with the Offering and all the securities underlying
such units (collectively, the “Registrable Securities”). On such occasion, the Company will use its best
efforts to file a registration statement or a post-effective amendment to the Registration Statement covering the Registrable Securities
within sixty days after receipt of the Initial Demand Notice and use its best efforts to have such registration statement or post-effective
amendment declared effective as soon as possible thereafter. The demand for registration may be made at any time during a period
of five years beginning on the Effective Date. The Initial Demand Notice shall specify the number of shares of Registrable Securities
proposed to be sold and the intended method(s) of distribution thereof. The Company will notify all holders of the Purchase Options
and/or Registrable Securities of the demand within ten days from the date of the receipt of any such Initial Demand Notice. Each
holder of Registrable Securities who wishes to include all or a portion of such holder’s Registrable Securities in the Demand
Registration (each such holder including shares of Registrable Securities in such registration, a “Demanding Holder”)
shall so notify the Company within fifteen (15) days after the receipt by the holder of the notice from the Company. Upon any such
request, the Demanding Holders shall be entitled to have their Registrable Securities included in the Demand Registration, subject
to Section 5.1.4. The Company shall not be required to effect more than one (1) Demand Registration under this Section 5.1 in respect
of all Registrable Securities.

 

5.1.2         Effective
Registration. A registration will not count as a Demand Registration until the registration statement filed with the Commission
with respect to such Demand Registration has been declared effective and the Company has complied with all of its obligations under
this Agreement with respect thereto.

 

5.1.3         Underwritten
Offering. If the Majority Holders so elect and such holders so advise the Company as part of the Initial Demand Notice, the
offering of such Registrable Securities pursuant to such Demand Registration shall be in the form of an underwritten offering.
In such event, the right of any holder to include its Registrable Securities in such registration shall be conditioned upon such
holder’s participation in such underwriting and the inclusion of such holder’s Registrable Securities in the underwriting
to the extent provided herein. All Demanding Holders proposing to distribute their securities through such underwriting shall enter
into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Majority
Holders.

 

    	 	5	 

     

    

 

5.1.4         Reduction
of Offering. If the managing underwriter or underwriters for a Demand Registration that is to be an underwritten offering advises
the Company and the Demanding Holders in writing that the dollar amount or number of shares of Registrable Securities which the
Demanding Holders desire to sell, taken together with all other shares of Common Stock or other securities which the Company desires
to sell and the shares of Common Stock, if any, as to which registration has been requested pursuant to written contractual piggy-back
registration rights held by other stockholders of the Company who desire to sell, exceeds the maximum dollar amount or maximum
number of shares that can be sold in such offering without adversely affecting the proposed offering price, the timing, the distribution
method, or the probability of success of such offering (such maximum dollar amount or maximum number of shares, as applicable,
the “Maximum Number of Shares”), then the Company shall include in such registration: (i) first,
the Registrable Securities as to which Demand Registration has been requested by the Demanding Holders (pro rata in accordance
with the number of shares that each such Person has requested be included in such registration, regardless of the number of shares
held by each such Person (such proportion is referred to herein as “Pro Rata”)) that can be sold without
exceeding the Maximum Number of Shares; (ii) second, to the extent that the Maximum Number of Shares has not been reached
under the foregoing clause (i), the shares of Common Stock or other securities that the Company desires to sell that can be sold
without exceeding the Maximum Number of Shares; (iii) third, to the extent that the Maximum Number of Shares has not been
reached under the foregoing clauses (i) and (ii), the shares of Common Stock or other securities registrable pursuant to the
terms of the Registration Rights Agreement between the Company and the initial investors in the Company, dated as of [_________],
2016 (the “Registration Rights Agreement” and such registrable securities, the “Investor
Securities”) as to which “piggy-back” registration has been requested by the holders thereof, Pro Rata,
that can be sold without exceeding the Maximum Number of Shares; and (iv) fourth, to the extent that the Maximum Number of
Shares have not been reached under the foregoing clauses (i), (ii), and (iii), the shares of Common Stock or other securities
for the account of other persons that the Company is obligated to register pursuant to written contractual arrangements with such
persons and that can be sold without exceeding the Maximum Number of Shares.

 

5.1.5         Withdrawal.
If a majority-in-interest of the Demanding Holders disapprove of the terms of any underwriting or are not entitled to include all
of their Registrable Securities in any offering, such majority-in-interest of the Demanding Holders may elect to withdraw from
such offering by giving written notice to the Company and the underwriter or underwriters of their request to withdraw prior to
the effectiveness of the registration statement filed with the Commission with respect to such Demand Registration. If the majority-in-interest
of the Demanding Holders withdraws from a proposed offering relating to a Demand Registration, then the Company does not have to
continue its obligations under Section 5.1 with respect to such proposed offering.

 

5.1.6         Terms.
The Company shall bear all fees and expenses attendant to registering the Registrable Securities, including the expenses of one
legal counsel selected by the Holders to represent them in connection with the sale of the Registrable Securities, but the Holders
shall pay any and all underwriting commissions. The Company agrees to use its reasonable best efforts to qualify or register the
Registrable Securities in such states as are reasonably requested by the Majority Holder(s); provided, however, that in no event
shall the Company be required to register the Registrable Securities in a state in which such registration would cause (i) the
Company to be obligated to qualify to do business in such state, or would subject the Company to taxation as a foreign corporation
doing business in such jurisdiction or (ii) the principal stockholders of the Company to be obligated to escrow their shares
of capital stock of the Company. The Company shall use its best efforts to cause any registration statement or post-effective amendment
filed pursuant to the demand rights granted under Section 5.1.1 to remain effective for a period of nine consecutive months from
the effective date of such registration statement or post-effective amendment.

 

    	 	6	 

     

    

 

5.2         Piggy-Back
Registration.

 

5.2.1         Piggy-Back
Rights. If at any time during the seven year period commencing on the Effective Date the Company proposes to file a registration
statement under the Act with respect to an offering of equity securities, or securities or other obligations exercisable or exchangeable
for, or convertible into, equity securities, by the Company for its own account or for stockholders of the Company for their account
(or by the Company and by stockholders of the Company including, without limitation, pursuant to Section 5.1), other than a registration
statement (i) filed in connection with any employee stock option or other benefit plan, (ii) for an exchange offer or
offering of securities solely to the Company’s existing stockholders, (iii) for an offering of debt that is convertible
into equity securities of the Company or (iv) for a dividend reinvestment plan, then the Company shall (x) give written notice
of such proposed filing to the holders of Registrable Securities as soon as practicable but in no event less than ten (10) days
before the anticipated filing date, which notice shall describe the amount and type of securities to be included in such offering,
the intended method(s) of distribution, and the name of the proposed managing underwriter or underwriters, if any, of the offering,
and (y) offer to the holders of Registrable Securities in such notice the opportunity to register the sale of such number of shares
of Registrable Securities as such holders may request in writing within five (5) days following receipt of such notice (a “Piggy-Back
Registration”). The Company shall cause such Registrable Securities to be included in such registration and shall
use its best efforts to cause the managing underwriter or underwriters of a proposed underwritten offering to permit the Registrable
Securities requested to be included in a Piggy-Back Registration on the same terms and conditions as any similar securities of
the Company and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s)
of distribution thereof. All holders of Registrable Securities proposing to distribute their securities through a Piggy-Back Registration
that involves an underwriter or underwriters shall enter into an underwriting agreement in customary form with the underwriter
or underwriters selected for such Piggy-Back Registration.

 

5.2.2         Reduction
of Offering. If the managing underwriter or underwriters for a Piggy-Back Registration that is to be an underwritten offering
advises the Company and the holders of Registrable Securities in writing that the dollar amount or number of shares of Common Stock
which the Company desires to sell, taken together with shares of Common Stock, if any, as to which registration has been demanded
pursuant to written contractual arrangements with persons other than the holders of Registrable Securities hereunder, the Registrable
Securities as to which registration has been requested under this Section 5.2, and the shares of Common Stock, if any, as to which
registration has been requested pursuant to the written contractual piggy-back registration rights of other stockholders of the
Company, exceeds the Maximum Number of Shares, then the Company shall include in any such registration:

 

    	 	7	 

     

    

 

(a)         If
the registration is undertaken for the Company’s account: (A) first, the shares of Common Stock or other securities
that the Company desires to sell that can be sold without exceeding the Maximum Number of Shares; (B) second, to the extent
that the Maximum Number of Shares has not been reached under the foregoing clause (A), the shares of Common Stock or other
securities, if any, comprised of Registrable Securities and Investor Securities, as to which registration has been requested pursuant
to the applicable written contractual piggy-back registration rights of such security holders, Pro Rata, that can be sold without
exceeding the Maximum Number of Shares; and (C) third, to the extent that the Maximum Number of shares has not been reached
under the foregoing clauses (A) and (B), the shares of Common Stock or other securities for the account of other persons that
the Company is obligated to register pursuant to written contractual piggy-back registration rights with such persons and that
can be sold without exceeding the Maximum Number of Shares;

 

(b)         If
the registration is a “demand” registration undertaken at the demand of holders of Investor Securities, (A) first,
the shares of Common Stock or other securities for the account of the demanding persons, Pro Rata, that can be sold without exceeding
the Maximum Number of Shares; (B) second, to the extent that the Maximum Number of Shares has not been reached under the foregoing
clause (A), the shares of Common Stock or other securities that the Company desires to sell that can be sold without exceeding
the Maximum Number of Shares; (C) third, to the extent that the Maximum Number of Shares has not been reached under the foregoing
clauses (A) and (B), the shares of Registrable Securities, Pro Rata, as to which registration has been requested pursuant
to the terms hereof, that can be sold without exceeding the Maximum Number of Shares; and (D) fourth, to the extent that the
Maximum Number of Shares has not been reached under the foregoing clauses (A), (B) and (C), the shares of Common Stock or
other securities for the account of other persons that the Company is obligated to register pursuant to written contractual arrangements
with such persons, that can be sold without exceeding the Maximum Number of Shares; and

 

(c)         If
the registration is a “demand” registration undertaken at the demand of persons other than either the holders of Registrable
Securities or of Investor Securities, (A) first, the shares of Common Stock or other securities for the account of the demanding
persons that can be sold without exceeding the Maximum Number of Shares; (B) second, to the extent that the Maximum Number of Shares
has not been reached under the foregoing clause (A), the shares of Common Stock or other securities that the Company desires to
sell that can be sold without exceeding the Maximum Number of Shares; (C) third, to the extent that the Maximum Number of Shares
has not been reached under the foregoing clauses (A) and (B), collectively the shares of Common Stock or other securities comprised
of Registrable Securities and Investor Securities, Pro Rata, as to which registration has been requested pursuant to the terms
hereof and of the Registration Rights Agreement, as applicable, that can be sold without exceeding the Maximum Number of Shares;
and (D) fourth, to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (A), (B) and (C),
the shares of Common Stock or other securities for the account of other persons that the Company is obligated to register pursuant
to written contractual arrangements with such persons, that can be sold without exceeding the Maximum Number of Shares.

 

    	 	8	 

     

    

 

5.2.3         Withdrawal.
Any holder of Registrable Securities may elect to withdraw such holder’s request for inclusion of Registrable Securities
in any Piggy-Back Registration by giving written notice to the Company of such request to withdraw prior to the effectiveness of
the registration statement. The Company (whether on its own determination or as the result of a withdrawal by persons making a
demand pursuant to written contractual obligations) may withdraw a registration statement at any time prior to the effectiveness
of the registration statement. Notwithstanding any such withdrawal, the Company shall pay all expenses incurred by the holders
of Registrable Securities in connection with such Piggy-Back Registration as provided in Section 5.2.4.

 

5.2.4         Terms.
The Company shall bear all fees and expenses attendant to registering the Registrable Securities, including the expenses of one
legal counsel selected by the Holders to represent them in connection with the sale of the Registrable Securities but the Holders
shall pay any and all underwriting commissions related to the Registrable Securities. In the event of such a proposed registration,
the Company shall furnish the then Holders of outstanding Registrable Securities with not less than fifteen days written notice
prior to the proposed date of filing of such registration statement. Such notice to the Holders shall continue to be given for
each applicable registration statement filed (during the period in which the Purchase Option is exercisable) by the Company until
such time as all of the Registrable Securities have been registered and sold. The Holders of the Registrable Securities shall exercise
the “piggy-back” rights provided for herein by giving written notice, within ten days of the receipt of the Company’s
notice of its intention to file a registration statement. The Company shall use its best efforts to cause any registration statement
filed pursuant to the above “piggyback” rights to remain effective for at least nine months from the date that the
Holders of the Registrable Securities are first given the opportunity to sell all of such securities.

 

5.3         Intentionally
Omitted.

 

5.4         General
Terms.

 

5.4.1         Indemnification.
The Company shall indemnify the Holder(s) of the Registrable Securities to be sold pursuant to any registration statement hereunder
and each person, if any, who controls such Holders within the meaning of Section 15 of the Act or Section 20(a) of the Securities
Exchange Act of 1934, as amended (“Exchange Act”), against all loss, claim, damage, expense or liability
(including all reasonable attorneys’ fees and other expenses reasonably incurred in investigating, preparing or defending
against litigation, commenced or threatened, or any claim whatsoever whether arising out of any action between the underwriter
and the Company or between the underwriter and any third party or otherwise) to which any of them may become subject under the
Act, the Exchange Act or otherwise, arising from such registration statement but only to the same extent and with the same effect
as the provisions pursuant to which the Company has agreed to indemnify the underwriters contained in Section 5 of the Underwriting
Agreement between the Company, Chardan and the other underwriters named therein dated the Effective Date. The Holder(s) of the
Registrable Securities to be sold pursuant to such registration statement, and their successors and assigns, shall severally, and
not jointly, indemnify the Company, its officers and directors and each person, if any, who controls the Company within the meaning
of Section 15 of the Act or Section 20(a) of the Exchange Act, against all loss, claim, damage, expense or liability (including
all reasonable attorneys’ fees and other expenses reasonably incurred in investigating, preparing or defending against any
claim whatsoever) to which they may become subject under the Act, the Exchange Act or otherwise, arising from information furnished
by or on behalf of such Holders, or their successors or assigns, in writing, for specific inclusion in such registration statement
to the same extent and with the same effect as the provisions contained in Section 5 of the Underwriting Agreement pursuant to

    	 	9	 

     

    

 

5.4.2         Exercise
of Purchase Options. Nothing contained in this Purchase Option shall be construed as requiring the Holder(s) to exercise their
Purchase Options or Rights or Warrants underlying such Purchase Options prior to or after the initial filing of any registration
statement or the effectiveness thereof.

 

5.4.3         Documents
Delivered to Holders. The Company shall furnish Chardan, as representative of the Holders participating in any of the foregoing
offerings, a signed counterpart, addressed to the participating Holders, of (i) an opinion of counsel to the Company, dated the
effective date of such registration statement (and, if such registration includes an underwritten public offering, an opinion dated
the date of the closing under any underwriting agreement related thereto), and (ii) a “cold comfort” letter dated the
effective date of such registration statement (and, if such registration includes an underwritten public offering, a letter dated
the date of the closing under the underwriting agreement) signed by the independent public accountants who have issued a report
on the Company’s financial statements included in such registration statement, in each case covering substantially the same
matters with respect to such registration statement (and the prospectus included therein) and, in the case of such accountants’
letter, with respect to events subsequent to the date of such financial statements, as are customarily covered in opinions of issuer’s
counsel and in accountants’ letters delivered to underwriters in underwritten public offerings of securities. The Company
shall also deliver promptly to Chardan, as representative of the Holders participating in the offering, the correspondence and
memoranda described below and copies of all correspondence between the Commission and the Company, its counsel or auditors and
all memoranda relating to discussions with the Commission or its staff with respect to the registration statement and permit Chardan,
as representative of the Holders, to do such investigation, upon reasonable advance notice, with respect to information contained
in or omitted from the registration statement as it deems reasonably necessary to comply with applicable securities laws or rules
of FINRA. Such investigation shall include access to books, records and properties and opportunities to discuss the business of
the Company with its officers and independent auditors, all to such reasonable extent and at such reasonable times and as often
as Chardan, as representative of the Holders, shall reasonably request. The Company shall not be required to disclose any confidential
information or other records to Chardan, as representative of the Holders, or to any other person, until and unless such persons
shall have entered into reasonable confidentiality agreements (in form and substance reasonably satisfactory to the Company), with
the Company with respect thereto.

 

    	 	10	 

     

    

5.4.4         Underwriting
Agreement. The Company shall enter into an underwriting agreement with the managing underwriter(s), if any, selected by any
Holders whose Registrable Securities are being registered pursuant to this Section 5, which managing underwriter shall be reasonably
acceptable to the Company. Such agreement shall be reasonably satisfactory in form and substance to the Company, each Holder and
such managing underwriters, and shall contain such representations, warranties and covenants by the Company and such other terms
as are customarily contained in agreements of that type used by the managing underwriter. The Holders shall be parties to any underwriting
agreement relating to an underwritten sale of their Registrable Securities and may, at their option, require that any or all the
representations, warranties and covenants of the Company to or for the benefit of such underwriters shall also be made to and for
the benefit of such Holders. Such Holders shall not be required to make any representations or warranties to or agreements with
the Company or the underwriters except as they may relate to such Holders and their intended methods of distribution. Such Holders,
however, shall agree to such covenants and indemnification and contribution obligations for selling stockholders as are customarily
contained in agreements of that type used by the managing underwriter. Further, such Holders shall execute appropriate custody
agreements and otherwise cooperate fully in the preparation of the registration statement and other documents relating to any offering
in which they include securities pursuant to this Section 5. Each Holder shall also furnish to the Company such information regarding
itself, the Registrable Securities held by it, and the intended method of disposition of such securities as shall be reasonably
required to effect the registration of the Registrable Securities.

 

5.4.5         Rule
144 Sale. Notwithstanding anything contained in this Section 5 to the contrary, the Company shall have no obligation pursuant
to Sections 5.1 or 5.2 to use its best efforts to obtain the registration of Registrable Securities held by any Holder (i) where
such Holder would then be entitled to sell under Rule 144 within any three-month period (or such other period prescribed under
Rule 144 as may be provided by amendment thereof) all of the Registrable Securities then held by such Holder, and (ii) where the
number of Registrable Securities held by such Holder is within the volume limitations under paragraph (e) of Rule 144 (calculated
as if such Holder were an affiliate within the meaning of Rule 144).

 

5.4.6         Supplemental
Prospectus. Each Holder agrees, that upon receipt of any notice from the Company of the happening of any event as a result
of which the prospectus included in the registration statement, as then in effect, includes an untrue statement of a material fact
or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light
of the circumstances then existing, such Holder will immediately discontinue disposition of Registrable Securities pursuant to
the registration statement covering such Registrable Securities until such Holder’s receipt of the copies of a supplemental
or amended prospectus, and, if so desired by the Company, such Holder shall deliver to the Company (at the expense of the Company)
or destroy (and deliver to the Company a certificate of such destruction) all copies, other than permanent file copies then in
such Holder’s possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice.

 

6.           Adjustments.

 

6.1         Adjustments
to Exercise Price and Number of Securities. The Exercise Price and the number of Units underlying the Purchase Option shall
be subject to adjustment from time to time as hereinafter set forth:

 

    	 	11	 

     

    

 

6.1.1         Stock
Dividends - Split-Ups. If after the date hereof, and subject to the provisions of Section 6.4 below, the number of outstanding
shares of Common Stock is increased by a stock dividend payable in shares of Common Stock or by a split-up of shares of Common
Stock or other similar event, then, on the effective date thereof, the number of shares of Common Stock underlying each of the
Units purchasable hereunder shall be increased in proportion to such increase in outstanding shares. In such case, (i) the number
of shares of Common Stock underlying the Rights underlying each of the Units purchasable hereunder shall be adjusted accordingly,
and (ii) the number of shares of Common Stock, and the exercise price applicable thereto, underlying the Warrants underlying each
of the Units purchasable hereunder shall be adjusted in accordance with the terms of the Warrants.

 

6.1.2         Aggregation
of Shares. If after the date hereof, and subject to the provisions of Section 6.3, the number of outstanding shares of Common
Stock is decreased by a consolidation, combination or reclassification of shares of Common Stock or other similar event, then,
on the effective date thereof, the number of shares of Common Stock underlying each of the Units purchasable hereunder shall be
decreased in proportion to such decrease in outstanding shares. In such case, (i) the number of shares of Common Stock underlying
the Rights underlying each of the Units purchasable hereunder shall be adjusted accordingly, and (ii) the number of shares of Common
Stock, and the exercise price applicable thereto, underlying the Warrants underlying each of the Units purchasable hereunder shall
be adjusted in accordance with the terms of the Warrants.

 

6.1.3         Replacement
of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding shares of Common
Stock other than a change covered by Section 6.1.1 or 6.1.2 hereof or that solely affects the par value of such shares of Common
Stock, or in the case of any merger or consolidation of the Company with or into another corporation (other than a consolidation
or merger in which the Company is the continuing corporation and that does not result in any reclassification or reorganization
of the outstanding shares of Common Stock), or in the case of any sale or conveyance to another corporation or entity of the property
of the Company as an entirety or substantially as an entirety in connection with which the Company is dissolved, the Holder of
this Purchase Option shall have the right thereafter (until the expiration of the right of exercise of this Purchase Option) to
receive upon the exercise hereof, for the same aggregate Exercise Price payable hereunder immediately prior to such event, the
kind and amount of shares of stock or other securities or property (including cash) receivable upon such reclassification, reorganization,
merger or consolidation, or upon a dissolution following any such sale or transfer, by a Holder of the number of shares of Common
Stock of the Company obtainable upon exercise of this Purchase Option and the underlying Rights and Warrants immediately prior
to such event; and if any reclassification also results in a change in the Common Stock covered by Section 6.1.1 or 6.1.2, then
such adjustment shall be made pursuant to Sections 6.1.1, 6.1.2 and this Section 6.1.3. The provisions of this Section 6.1.3 shall
similarly apply to successive reclassifications, reorganizations, mergers or consolidations, sales or other transfers.

 

6.1.4         Changes
in Form of Purchase Option. This form of Purchase Option need not be changed because of any change pursuant to this Section,
and Purchase Options issued after such change may state the same Exercise Price and the same number of Units as are stated in the
Purchase Options initially issued pursuant to this Agreement. The acceptance by any Holder of the issuance of new Purchase Options
reflecting a required or permissive change shall not be deemed to waive any rights to an adjustment occurring after the Commencement
Date or the computation thereof.

 

    	 	12	 

     

    

 

6.2         Substitute
Purchase Option. In case of any consolidation of the Company with, or merger of the Company with, or merger of the Company
into, another corporation (other than a consolidation or merger which does not result in any reclassification or change of the
outstanding shares of Common Stock), the corporation formed by such consolidation or merger shall execute and deliver to the Holder
a supplemental Purchase Option providing that the holder of each Purchase Option then outstanding or to be outstanding shall have
the right thereafter (until the stated expiration of such Purchase Option) to receive, upon exercise of such Purchase Option, the
kind and amount of shares of stock and other securities and property receivable upon such consolidation or merger, by a holder
of the number of shares of Common Stock of the Company for which such Purchase Option might have been exercised immediately prior
to such consolidation, merger, sale or transfer. Such supplemental Purchase Option shall provide for adjustments which shall be
identical to the adjustments provided in Section 6. The above provision of this Section shall similarly apply to successive consolidations
or mergers.

 

6.3         Elimination
of Fractional Interests. The Company shall not be required to issue certificates representing fractions of a share of Common
Stock, Rights or Warrants upon the exercise of the Purchase Option, nor shall it be required to issue scrip or pay cash in lieu
of any fractional interests, it being the intent of the parties that all fractional interests shall be eliminated by rounding any
fraction up to the nearest whole number of Rights, Warrants, Common Stock or other securities, properties or rights.

 

7.         Reservation
and Listing. The Company shall at all times reserve and keep available out of its authorized Common Stock, solely for the purpose
of issuance upon exercise of the Purchase Options or the Rights or the Warrants underlying the Purchase Option, such number of
shares of Common Stock or other securities, properties or rights as shall be issuable upon the exercise thereof. The Company covenants
and agrees that, upon exercise of the Purchase Options and payment of the Exercise Price therefor, all Common Stock and other securities
issuable upon such exercise shall be duly and validly issued, fully paid and non-assessable and not subject to preemptive rights
of any stockholder. The Company further covenants and agrees that upon exercise of the Warrants underlying the Purchase Options
and payment of the respective Warrant exercise price therefor, all Common Stock and other securities issuable upon such exercise
shall be duly and validly issued, fully paid and non-assessable and not subject to preemptive rights of any stockholder. As long
as the Purchase Options shall be outstanding, the Company shall use its best efforts to cause all (i) Units and Common Stock issuable
upon exercise of the Purchase Options, (ii) Rights issuable upon exercise of the Purchase Options, (iii) Warrants issuable upon
exercise of the Purchase Options and (iv) Common Stock issuable upon conversion of the Rights and exercise of the Warrants included
in the Units issuable upon exercise of the Purchase Option to be listed (subject to official notice of issuance) on all securities
exchanges (or, if applicable on the OTC Bulletin Board or OTC Markets Group, Inc. or any successor trading market) on which the
Common Stock or the Public Warrants issued to the public in connection herewith may then be listed and/or quoted.

8.           Certain
Notice Requirements.

 

8.1         Holder’s
Right to Receive Notice. Nothing herein shall be construed as conferring upon the Holders the right to vote or consent as a

If, however, at any time prior to the expiration of the Purchase Options and their exercise, any of the events described in Section
8.2 shall occur, then, in one or more of said events, the Company shall give written notice of such event at least fifteen days

to such dividend, distribution, conversion or exchange of securities or subscription rights, or entitled to vote on such proposed
dissolution, liquidation, winding up or sale. Such notice shall specify such record date or the date of the closing of the transfer
books, as the case may be. Notwithstanding the foregoing, the Company shall deliver to each Holder a copy of each notice given
to the other stockholders of the Company at the same time and in the same manner that such notice is given to the stockholders.

a dividend or distribution payable otherwise than in cash, or a cash dividend or distribution payable otherwise than out of retained
earnings, as indicated by the accounting treatment of such dividend or distribution on the books of the Company, or (ii) the Company
shall offer to all the holders of its Common Stock any additional shares of capital stock of the Company or securities convertible
into or exchangeable for shares of capital stock of the Company, or any option, right or warrant to subscribe therefor, or (iii)
a dissolution, liquidation or winding up of the Company (other than in connection with a consolidation or merger) or a sale of
all or substantially all of its property, assets and business shall be proposed.

 

8.3         Notice
of Change in Exercise Price. The Company shall, promptly after an event requiring a change in the Exercise Price pursuant to
Section 6 hereof, send notice to the Holders of such event and change (“Price Notice”). The Price Notice

by the Company’s President and Chief Financial Officer.

PRIVATE UNITS PURCHASE AGREEMENT

 

THIS PRIVATE UNITS
PURCHASE AGREEMENT, dated as of [_____], 2016 (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 311,000 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:  

 

AGREEMENT

 

Section 1. Authorization,
Purchase and Sale; Terms of the Private Units.

 

A. Authorization
of the Private Units. The Company has duly authorized the issuance and sale of the Private Units to the Purchaser.

 

B. Purchase
and Sale of the Private Units. On the date that the Public Offering is consummated or at such earlier time and date
as may be mutually agreed by the Purchaser and the Company (the “Closing Date”), the Company shall issue and sell
to the Purchaser, and the Purchaser shall purchase from the Company, the Private Units at a price of $10.00 per unit for
an aggregate purchase price of $ 2,750,000 (or $ 3,110,000 if the underwriters’ over-allotment option in connection
with the Public Offering is exercised in full) (the “Purchase Price”), which shall be paid by wire transfer of
immediately available funds to Continental Stock Transfer & Trust Company, acting as escrow agent in connection with the
sale of the Private Units, at least 24 hours prior to the effective date of the registration statement relating to the Public
Offering, to hold in a non-interest bearing account until the Public Offering is consummated. On the Closing Date, upon the
deposit of the Purchase Price into the Trust Account by Continental Stock Transfer & Trust Company, the Company shall
deliver a certificate evidencing the Private Units duly registered in the Purchaser’s name to the Purchaser.

 

C. Terms of the
Private Units.

(iii) At the time of
the closing of the Public Offering, the Company and the Purchaser shall enter into a registration rights agreement (the “Registration
Rights Agreement”) pursuant to which the Company will grant certain registration rights to the Purchaser relating to the

planning purposes, (iv) by virtue of the laws of descent and distribution upon death of the Purchaser, (v) pursuant to a qualified
domestic relations order, (vi) by private sales at prices no greater than the price at which the Private Units were originally

combination, in each case, except for clause (vii), on the condition that such transfers may be implemented only upon the respective

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.

 

(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.

 

    3 

     

    

 

(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.
