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 HUDSON ACQUISITION I CORP., a Delaware corporation (the “Company”), Holder is entitled,
at any time or from time to time on or after the consummation of the initial Business Combination (“Commencement Date”)
(as described in the Company’s registration statement (“Registration Statement”) pursuant to which Units
are offered for sale to the public in Company’s initial public offering (“Offering”)) until the earlier
of (i) the liquidation of the Company’s trust account if the Company has not completed a business combination within the required
time periods and (ii) [ ][1], 2027 (the “Expiration Date”), but not thereafter, to subscribe for,
purchase and receive, in whole or in part, up to fifty thousand (50,000) units (“Units”) of the Company (or
up to fifty-seven thousand and five hundred (57,500) Units with the exercise of the over-allotment option in full in the Offering), each
Unit consisting of one (1) share of common stock of the Company, with a par value $0.0001 per share (“Common Stock”),
and one (1) right to receive one-eight (1/8) of a share of Common Stock upon the consummation of a Business Combination (“Right(s)”).
Each Right has the same terms as the right included in the units being registered for sale to the public by way of the Registration Statement
(“Public Rights”). 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 $11.50 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 shares of Common Stock and Rights) 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
OF PUrchase option.

 

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 null and void without further force or effect, and
all rights represented hereby shall cease and expire.

 

2.2    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 shares of Common Stock) in the manner required by Section 2.1, and subject to Section
6.1 hereof, 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 and Rights comprising that number of Units) equal to the number of Units to be exercised multiplied by
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 the Units, shares of Common Stock and Public Rights are still trading, (i) if the Units are listed
on a national securities exchange or quoted on the OTC Bulletin Board (or successor exchange), the average reported last sale price of
the Units in the principal trading market for the Units as reported by the exchange, Nasdaq or the Financial Industry Regulatory Authority
(“FINRA”), as the case may be, for the three trading days preceding the date in question; or (ii) if the Units
are not listed on a national securities exchange or quoted on the OTC Bulletin Board (or successor exchange), but is traded in the residual
over-the-counter market, the average reported last sale price for Units for the three trading days preceding the date in question for
which such quotations are reported by the Pink Sheets, LLC or similar publisher of such quotations; (B) in the event that the Units are
not still trading but the shares of Common Stock and Public Rights underlying the Units are still trading, the aggregate of (i) the product
of (x) the Current Market Price of the Common Stock and (y) the number of shares Common Stock underlying one Unit (which shall include
the portion of a share of Common Stock the holder of a Unit would automatically receive in connection with the Rights included in each
such Unit); or (C) in the event that the Units are not trading but the shares of Common Stock underlying the Units are still trading,
the product of (x) the Current Market Price of the Common Stock and (y) the number of shares of Common Stock underlying one Unit (which
shall include the portion of a share of Common Stock the holder of a Unit would automatically receive in connection with the Rights included
in each such Unit). The “Current Market Price” shall mean (i) if the Common Stock is listed on a national securities exchange
or quoted on the OTC Bulletin Board (or successor exchange), the average reported last sale price of the Common Stock in the principal
trading market for the Common Stock as reported by the exchange, Nasdaq or FINRA, as the case may be, for the three trading days preceding
the date in question; (ii) if the Common Stock is not listed on a national securities exchange or quoted on the OTC Bulletin Board (or
successor exchange), but are traded in the residual over-the-counter market, the average reported last sale price for the Common Stock
for the three (3) trading days preceding the date in question for which such quotations are reported by the Pink Sheets, LLC 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 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. 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,

or such portion of such number as shall be contemplated by any such assignment.

 

3.2    Restrictions

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 Hunter Taubman Fischer & Li LLC 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 U.S. Securities and Exchange Commission (the “Commission”)
and compliance with applicable state securities law has been established.

the Holder elects to exercise this Purchase Option by means of a cashless exercise as provided in Section 2.2 above) 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 Option 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 Option requested by the Majority Holders in the Initial Demand Notice and all of the securities underlying such Purchase
Option, including the Units, shares of Common Stock, Rights and the shares of Common Stock underlying the Rights and (ii) the securities
issued to the Holder prior to or concurrently with the Offering and all the securities underlying such securities (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 as expeditiously as possible within sixty (60) 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 from the Commencement Date and for a period
of five years beginning on the commencement of sales of the Offering. 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 Option 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 Registrations under this Section 5.1 in respect
of all Registrable Securities.

 

5.1.2    Effective
Registration. Notwithstanding Section 5.1.5, 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 Purchase Option 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.

 

5.1.4    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 and Chardan, dated
as of [●], 2022 (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 has 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.

 

    4

     

    

 

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, provided that, any such withdrawal will not count as the Demand Registration if the Demanding Holders
pay all of the Company’s out-of-pocket expenses, with respect to such withdrawn registration.

 

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.

 

5.2   Piggy-Back
Registration.

 

5.2.1    Piggy-Back
Rights. If at any time during the seven year period commencing on the commencement of sales of the Offering 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

     

    

 

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 the 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 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

to register pursuant to written contractual arrangements with such persons, that can be sold without exceeding the maximum Number of Shares;
and

 

(c)    If

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

Agreement, as applicable, that can be sold without exceeding the maximum Number of Shares; and (D) fourth, to the extent that the maximum

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.

 

    6

     

    

 

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    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 (“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 (“Underwriting Agreement”). 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
for specific inclusion in such registration statement or arising from any omission or the alleged omission to state a material fact required
to be stated therein or necessary to make the statement contained therein not misleading in connection with the registration of the Registrable
Securities, 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 Option. Nothing contained in this Purchase Option shall be construed as requiring the Holder(s) to exercise their Purchase
Option.

 

5.3.3    Documents
Delivered to Holders. The Company shall furnish Chardan, for as long as it is a Holder, 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.

 

    7

     

    

 

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.

 

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, or (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.

 

5.3.7   Holder
Obligations. No Holder may participate in any underwritten offering pursuant to this Section
5 unless such Holder (i) agrees to sell only the Holder’s Registrable Securities on the basis reasonably provided in any underwriting
agreement, and (ii) completes, executes and delivers any and all questionnaires, powers of attorney, custody agreements, indemnities,
underwriting agreements and other documents reasonably and customarily required by or under the terms of any underwriting agreement.

 

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 outstanding
shares of Common Stock is increased by a stock dividend payable in 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.

 

    8

     

    

 

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 the 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 and the Exercise Price shall be proportionately increased.

 

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 company (other than a consolidation or merger
in which the Company is the continuing entity 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 company 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 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 immediately
prior to such event; and if any reclassification also results in a change in shares of 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 a
Purchase Option issued after such change may state the same Exercise Price and the same number of Units as are stated in the Purchase
Option as initially issued. The acceptance by any Holder of the issuance of a new Purchase Option 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
entity (other than a consolidation or merger which does not result in any reclassification or change of the outstanding shares of Common
Stock), the entity 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 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
or Rights 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 or down to the nearest
whole number of shares of Common Stock, Rights or other securities, properties or rights.

 

    9

     

    

 

7.    RESERVATION
AND LISTING. The Company shall at all times reserve and keep available out of its authorized but unissued shares of Common
Stock, solely for the purpose of issuance upon exercise of the Purchase Option (including the shares of Common Stock underlying the Rights),
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 Option and payment of the Exercise Price therefor, all shares of 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 Option shall be outstanding, the Company shall use its best efforts to cause all (i)
Units and shares of Common Stock issuable upon exercise of the Purchase Option, (ii) Rights issuable upon exercise of the Purchase Option
and (iii) shares of Common Stock underlying the Rights included in the Units issuable upon exercise of the Purchase Option to be listed
and/or quoted (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 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 stockholders of the Company. If, however, at
any time prior to the expiration of the Purchase Option and its exercise, any of the events described in Section 8.2 shall occur,
then, in each such event, 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 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 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
Chief Executive 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:

9.5    Governing
Law; Submission to Jurisdiction. This Purchase Option shall be governed by and construed and enforced in accordance with the internal

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,
