		1.	Purchase Option.



 


THIS CERTIFIES THAT, in consideration of
$100 duly paid by or on behalf of [_____________] (the “Holder”), as registered owner of this Purchase
Option, to Jensyn Acquisition Corp. (the “Company”), the Holder is entitled, at any time or from time
to time upon the later of the consummation of a Business Combination or [__________], 2015 (the “Commencement Date”),
and at or before 5:00 p.m., New York City local time, on the five-year anniversary of the effective date (the “Effective
Date”) of the Company’s registration statement on Form S-1 (File No. 333-_____________) (the “Registration
Statement”) pursuant to which Units are offered for sale to the public (the “Offering”),
but not thereafter (the “Expiration Date”), to subscribe for, purchase and receive, in whole or in part,
up to five hundred thousand (500,000) 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 (a “Right”)
entitling the holder to automatically receive one-tenth (1/10) of a share of Common Stock upon consummation of a Business Combination,
and one warrant (a “Warrant”) entitling the holder thereof to purchase one-half of one share of Common
Stock at a price of $12.00 per full share, as more fully described in the Registration Statement. 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 one hundred percent
(100%) of the initial public offering price 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, in substantially
the form attached hereto as Exhibit A (the “Exercise Form”) 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 (the “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.”


 


		2.3.	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 neither the Units, Rights nor Warrants are still trading, (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 (x) the one-tenth (1/10) of a share of Common Stock the holder of a Unit will automatically receive in connection with
the Right included in each such Unit and (y) the one-half (1/2) of a share of Common Stock underlying the Warrant included in each
such Unit; (B) in the event that the Units, Common Stock, Rights and Warrants are still trading, (i) if the Units are listed on
a national securities exchange, the average reported last sale price of the Units in the principal trading market for the Units
as reported by the exchange for the five trading days preceding the date in question; or (ii) if the Units are not listed on a
national securities exchange, but are quoted on the residual over-the-counter market, the average reported last sale price for
Units on the five trading days preceding the date in question for which such quotations are reported by the OTC Markets or similar
publisher of such quotations; and (C) in the event that the Units are not still trading but the Common Stock, Rights and Warrants
are still trading, the Current Market Price of the Common Stock plus (i) the product of (x) the Current Market Price of the Rights
and (y) the number of shares of Common Stock in the Rights that will automatically convert to Common Stock included in one Unit
and (ii) the product of (x) the Current Market Price of the Warrants and (y) the number of shares of Common Stock in the Warrants
that will be exercisable for Common Stock included in one Unit. The “Current Market Price” shall mean (i) if the Common
Stock, Rights or Warrants (as the case may be) is/are listed on a national securities exchange, the average reported last sale
price of the Common Stock, Rights or Warrants (as the case may be) in the principal trading market for the Common Stock, Rights
or Warrants (as the case may be) as reported by the exchange on the five trading days preceding the date in question; (ii) if the
Common Stock, Rights or Warrants (as the case may be) is/are not listed on a national securities exchange, but is/are traded in
the residual over-the-counter market, the average reported last sale price for the Common Stock, Rights or Warrants (as the case
may be) on the five trading days preceding the date in question for which such quotations are reported by the OTC Markets or similar
publisher of such quotations; and (iii) if the fair market value of the Common Stock cannot be determined pursuant to clause (i)
or (ii) above, such price as the Board of Directors of the Company shall determine, in good faith.

		2.3.2.	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 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 will not be entitled to exercise the 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, the Purchase Option will expire worthless.



 


		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) for a period of one year (including a period of 180 days pursuant to Rule 5110(g)(1) of the Conduct
Rules of the Financial Industry Regulatory Authority (“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 in substantially the form attached hereto as Exhibit B (the “Assignment
Form”), 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 Graubard
Miller 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 Form 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.



 




    	3



    	 



    

 


		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 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, the Rights, the Warrants and the
Common Stock included in the Rights and Warrants (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 obligated
to effect more than one (1) Demand Registrations 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.



 




    	4



    	 



    

 


		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 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 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 [__________],
2015 (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 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 this 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 any 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.



 




    	5



    	 



    

 


		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:



 


(a) If the registration is undertaken
for the Company’s account: (A) first, the 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 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 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 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 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 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


 




    	6



    	 



    

 


(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 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 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 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 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.


 


		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 any 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.	General Terms.



 


		5.3.1.	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 (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 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 which the underwriters have agreed to indemnify the Company.

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



 


		5.3.3.	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.



 


		5.3.4.	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.



 




    	8



    	 



    

 


		5.3.5.	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).



 


		5.3.6.	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:



 


		6.1.1.	Stock Dividends - Split-Ups. If after the date hereof, and subject to the provisions of
Section 6.3 below, the number of shares of outstanding Common Stock is increased by a stock dividend payable in Common Stock or
by a split-up 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, the number of shares of Common Stock included in the Right and the Warrant included in each of the Units purchasable
hereunder shall be adjusted in accordance with the terms of the Rights and 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 shares of outstanding Common Stock is decreased by a consolidation, combination or reclassification 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, the number of
shares of Common Stock included in the Right and the Warrant included in each of the Units purchasable hereunder shall be adjusted
in accordance with the terms of the Rights and the Warrants.



 


		6.1.3.	Replacement of Securities upon Reorganization, etc. In case of any reclassification or reorganization
of the outstanding 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 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 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 (including the shares of Common Stock included in the Rights and the Warrants) of the Company obtainable upon exercise of
this Purchase Option immediately prior to such event; and if any reclassification also results in a change in 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.



 




    	9



    	 



    

 


		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 Option 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.



 


		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 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 shares of Common Stock 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 down to the nearest whole number of Common Stock or other securities, properties, Rights or Warrants.



 


		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 Warrants
included in the Purchase Option, such number of shares of Common Stock or other securities, properties or rights as shall be issuable
upon the conversion 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 (including the Common Stock included in the Rights
and the Warrants) 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, (iv) Common Stock issuable upon conversion of the Rights included in the Units
issuable upon exercise of the Purchase Options and (v) Common Stock issuable upon exercise of the Warrants included in the Units
issuable upon exercise of the Purchase Options to be listed (subject to official notice of issuance) on all securities exchanges
on which the Units, the Common Stock, the Rights or the 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 stockholder for the election of directors or any other matter, or as having
any rights whatsoever as a stockholder of the Company. 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 prior to the date fixed as a record date or the date of closing the transfer
books for the determination of the stockholders entitled 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.



 


		8.2.	Events Requiring Notice. The Company shall be required to give the notice described in this
Section 8 upon one or more of the following events: (i) if the Company shall take a record of the holders of its Common Stock for
the purpose of entitling them to receive 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 (a “Price
Notice”). The Price Notice shall describe the event causing the change and the method of calculating same and shall
be certified as being true and accurate by the Company’s President and Chief Financial Officer.



 


		8.4.	Transmittal of Notices. All notices, requests, consents and other communications under this
Purchase Option shall be in writing and shall be deemed to have been duly made when hand delivered, or mailed by express mail or
private courier service: (i) if to the registered Holder of the Purchase Option, to the address of such Holder as shown on the
books of the Company, or (ii) if to the Company, to the following address or to such other address as the Company may designate
by notice to the Holders:

		9.	Miscellaneous.



 


		9.1.	Amendments. The Company and Chardan may from time to time supplement or amend this Purchase
Option without the approval of any of the Holders in order to cure any ambiguity, to correct or supplement any provision contained
herein that may be defective or inconsistent with any other provisions herein, or to make any other provisions in regard to matters
or questions arising hereunder that the Company and Chardan may deem necessary or desirable and that the Company and Chardan deem
shall not adversely affect the interest of the Holders. All other modifications or amendments shall require the written consent
of and be signed by the party against whom enforcement of the modification or amendment is sought.



 


		9.2.	Headings. The headings contained herein are for the sole purpose of convenience of reference,
and shall not in any way limit or affect the meaning or interpretation of any of the terms or provisions of this Purchase Option.



 


		9.3.	Entire Agreement. This Purchase Option (together with the other agreements and documents
being delivered pursuant to or in connection with this Purchase Option) constitutes the entire agreement of the parties hereto
with respect to the subject matter hereof, and supersedes all prior agreements and understandings of the parties, oral and written,
with respect to the subject matter hereof.



 




    	11



    	 



    

 


		9.4.	Binding Effect. This Purchase Option shall inure solely to the benefit of, and shall be
binding upon, the Holder and the Company and their permitted assignees, respective successors, legal representative and assigns,
and no other person shall have or be construed to have any legal or equitable right, remedy or claim under or in respect of or
by virtue of this Purchase Option or any provisions herein contained.



 


		9.5.	Governing Law. This Agreement shall be governed by and construed and enforced in accordance
with the laws of the State of New York, without giving effect to conflicts of law principles that would result in the application
of the substantive laws of another jurisdiction.



 


		9.6.	Waiver, Etc. The failure of the Company or the Holder to at any time enforce any of the
provisions of this Purchase Option shall not be deemed or construed to be a waiver of any such provision, nor to in any way affect
the validity of this Purchase Option or any provision hereof or the right of the Company or any Holder to thereafter enforce each
and every provision of this Purchase Option. No waiver of any breach, non-compliance or non-fulfillment of any of the provisions
of this Purchase Option shall be effective unless set forth in a written instrument executed by the party or parties against whom
or which enforcement of such waiver is sought; and no waiver of any such breach, non-compliance or non-fulfillment shall be construed
or deemed to be a waiver of any other or subsequent breach or non-compliance.



 


		9.7.	Execution in Counterparts. This Purchase Option may be executed in one or more counterparts,
and by the different parties hereto in separate counterparts, each of which shall be deemed to be an original, but all of which
taken together shall constitute one and the same agreement, and shall become effective when one or more counterparts has been signed
by each of the parties hereto and delivered to each of the other parties hereto.



 


		9.8.	Exchange Agreement. As a condition of the Holder’s receipt and acceptance of this
Purchase Option, Holder agrees that, at any time prior to the complete exercise of this Purchase Option by Holder, if the Company
and Chardan enter into an agreement (an “Exchange Agreement”) pursuant to which they agree that all outstanding
Purchase Options will be exchanged for securities or cash or a combination of both, then Holder shall agree to such exchange and
become a party to the Exchange Agreement.
