Virax Biolabs Group Limited 


 


Warrant
To Purchase Ordinary Shares


 


Warrant No.: UW-1


Date of Issuance: ______ __, 2022 (“Issuance
Date”)


 


Virax Biolabs Group Limited,
a Cayman Island corporation (the “Company”), hereby certifies that, for good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, Boustead Securities, LLC, the registered holder hereof or its permitted assigns
(the “Holder”), is entitled, subject to the terms set forth below, to purchase from the Company, at the Exercise Price
(as defined below) then in effect, Company ordinary shares, par value $0.0001 (“Ordinary Shares”) (including any Warrants
to purchase shares issued in exchange, transfer or replacement hereof, the “Warrant”), at any time or times on or
after the date hereof but not after 11:59 p.m., Eastern Time, on the Expiration Date (as defined below), _____ (subject to adjustment
as provided herein) fully paid and non-assessable shares of Ordinary Shares (the “Warrant Shares”).


 


	1.	EXERCISE OF WARRANT.



 


(a)
Mechanics of Exercise. Subject to the terms and conditions hereof, this Warrant may be
exercised by the Holder on any day on or after the date hereof, in whole or in part, by delivery (whether via facsimile, email, or otherwise)
of a written notice, in the form attached hereto as Exhibit A (the “Exercise Notice”), of the Holder’s
election to exercise this Warrant, by submitting information including the then-applicable Exercise Price, number of Warrant Shares purchased
equal to or lower than the then-applicable number of Warrant Shares and the FMV (collectively, the “Exercise Information”).
Within one (1) Trading Day following an exercise of this Warrant as aforesaid, the Holder shall deliver payment to the Company of an amount
equal to the Exercise Price in effect on the date of such exercise multiplied by the number of Warrant Shares as to which this Warrant
was so exercised (the “Aggregate Exercise Price”) in cash or via wire transfer of immediately available funds if, subject
to the provisions of Section 1(d), the Holder has not notified the Company in such Exercise Notice that such exercise is made pursuant
to a Cashless Exercise (as defined in Section 1(d)) at a time and under circumstances which permit a Cashless Exercise. The Holder shall
not be required to deliver the original of this Warrant in order to effect an exercise hereunder. Execution and delivery of an Exercise
Notice with respect to less than all of the Warrant Shares shall have the same effect as cancellation of the original of this Warrant
and issuance of a new Warrant evidencing the right to purchase the remaining number of Warrant Shares. Execution and delivery of an Exercise
Notice for all of the then-remaining Warrant Shares shall have the same effect as cancellation of the original of this Warrant after delivery
of the Warrant Shares in accordance with the terms hereof. On or before the first (1st) Trading Day following the date on which
the Company has received an Exercise Notice, upon checking that the Exercise Information supplied by the Holder is accurate, the Company
shall transmit by facsimile or email an acknowledgment of confirmation of receipt of such Exercise Notice, in the form attached hereto
as Exhibit B, to the Holder and the Company’s transfer agent (the “Transfer Agent”). On or before
the second (2nd) Trading Day following the date on which the Company has received such Exercise Notice and, in the event that
the Holder has chosen to exercise in cash, the receipt of the payment of the Aggregate Exercise Price, the Company shall instruct the
Transfer Agent to issue to the Holder the number of Warrant Shares to which the Holder is entitled pursuant to such exercise and to, at
the sole direction of the Holder pursuant to the Exercise Notice, hold such Warrant Shares in electronic form at the Transfer Agent registered
in the Company’s share register in the name of the Holder or its designee (as indicated in the applicable Exercise Notice), or mail
to the Holder or, at the Holder’s instruction pursuant to the Exercise Notice, the Holder’s agent or designee, in each case,
sent by reputable overnight courier to the address as specified in the applicable Exercise Notice, a certificate, registered in the Company’s
share register in the name of the Holder or its designee (as indicated in the applicable Exercise Notice). Upon delivery of an Exercise
Notice and in the event that the Holder has chosen to exercise in cash, the Company’s receipt of the payment of the Aggregate Exercise
Price, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to
which this Warrant has been exercised, irrespective of the date of delivery of the certificates evidencing such Warrant Shares (as the
case may be). If this Warrant is submitted in connection with any exercise pursuant to this Section 1(a) and the total number of Warrant
Shares represented by this Warrant is greater than the number of Warrant Shares being acquired by the Holder upon an exercise, then, at
the request of the Holder, the Company shall as soon as practicable and in no event later than three (3) Business Days after any exercise
and at its own expense, issue and deliver to the Holder (or its designee) a new Warrant (in accordance with Section 7(d)) representing
the right to purchase the number of Warrant Shares purchasable immediately prior to such exercise under this Warrant, less the number
of Warrant Shares with respect to which this Warrant is exercised. No fractional Warrant Shares are to be issued upon the exercise of
this Warrant, but rather the number of Warrant Shares to be issued shall be rounded up to the nearest whole number. The Company will from
time to time promptly pay all taxes and charges that may be imposed upon the Company in respect of the issuance or delivery of Warrant
Shares upon the exercise of this Warrant, but the Company shall not be obligated to pay any transfer taxes in respect of this Warrant
or such shares.

(b)
Exercise Price. For purposes of this Warrant, “Exercise Price” means $____ per share, subject to adjustment
as provided herein.


 


(c)
Company’s Failure to Timely Deliver Securities. If the Company shall fail, for any reason or for no reason, to issue
to the Holder within two (2) Trading Days after receipt of the applicable Exercise Notice, a certificate for the number of Warrant Shares
to which the Holder is entitled and register such Warrant Shares on the Company’s share register, the Holder will have the right
to rescind such exercise. In addition to any other rights available to the Holder, if the Company shall fail, for any reason or for no
reason, to issue to the Holder within two (2) Trading Days after receipt of the applicable Exercise Notice, a certificate for the number
of Warrant Shares to which the Holder is entitled and register such Warrant Shares on the Company’s share register and if on or
after such second (2nd) Trading Day the Holder (or any other Person in respect, or on behalf, of the Holder) purchases (in
an open market transaction or otherwise) Ordinary Shares to deliver in satisfaction of a sale by the Holder of all or any portion of the
number of Warrant Shares, or a sale of a number of Warrant Shares equal to all or any portion of the number of Warrant Shares, issuable
upon such exercise that the Holder so anticipated receiving from the Company, then, in addition to all other remedies available to the
Holder, the Company shall, within three (3) Business Days after the Holder’s request and in the Holder’s discretion, either
(i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including reasonable brokerage commissions and
other reasonable out-of-pocket expenses, if any) for the Warrant Shares so purchased (including, without limitation, by any other Person
in respect, or on behalf, of the Holder) (the “Buy-In Price”), at which point the Company’s obligation to so
issue and deliver such certificate or credit the Holder’s balance account with DTC for the number of Warrant Shares to which the
Holder is entitled upon the Holder’s exercise hereunder (as the case may be) (and to issue such Warrant Shares) shall terminate,
or (ii) promptly honor its obligation to so issue and deliver to the Holder a certificate or certificates representing such Warrant Shares
or credit the Holder’s balance account with DTC for the number of Warrant Shares to which the Holder is entitled upon the Holder’s
exercise hereunder (as the case may be) and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over
the product of (A) such number of Warrant Shares multiplied by (B) the lowest Closing Sale Price of the Ordinary Shares on any Trading
Day during the period commencing on the date of the applicable Exercise Notice and ending on the date of such issuance and payment under
this clause (ii).


 






    2


     


    

 


(d)
Cashless Exercise. Notwithstanding anything contained herein to the contrary, the Holder may, in its sole discretion, exercise
this Warrant in whole or in part and, in lieu of making the cash payment otherwise contemplated to be made to the Company upon such exercise
in payment of the Aggregate Exercise Price, elect instead to receive upon such exercise the “Net Number” of Warrant Shares
determined according to the following formula (a “Cashless Exercise”), provided that the Holder may elect to cashless
exercise pursuant to this Section 1(d) only if B as set forth in the following formula is higher than C as set forth in the following
formula:


 


Net Number = (A x B) - (A
x C)


                                      B


 


For purposes of the foregoing
formula:


 


A= the total number of shares with respect
to which this Warrant is then being exercised.


 


B= the FMV


 


C= the Exercise
Price then in effect for the applicable Warrant Shares at the time of such exercise.


 


(e)
Disputes. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the number
of Warrant Shares to be issued pursuant to the terms hereof, the Company shall promptly issue to the Holder the number of Warrant Shares
that are not disputed and resolve such dispute in accordance with Section 14.


 


(f)
[Intentionally Left Blank].


 


(g)
Insufficient Authorized Shares. The Company shall at all times keep reserved for issuance under this Warrant a number of
shares of Ordinary Shares as shall be necessary to satisfy the Company’s obligation to issue Warrant Shares hereunder (without regard
to any limitation otherwise contained herein with respect to the number of Warrant Shares that may be acquirable upon exercise of this
Warrant). If, notwithstanding the foregoing, and not in limitation thereof, at any time while the Warrant remains outstanding the Company
does not have a sufficient number of authorized and unreserved shares of Ordinary Shares to satisfy its obligation to reserve for issuance
upon exercise of the Warrant at least a number of shares of Ordinary Shares equal to the number of shares of Ordinary Shares as shall
from time to time be necessary to effect the exercise of the Warrant then outstanding (the “Required Reserve Amount”)
(an “Authorized Share Failure”), then the Company shall immediately take all action necessary to increase the Company’s
authorized shares of Ordinary Shares to an amount sufficient to allow the Company to reserve the Required Reserve Amount for the Warrant
then outstanding. Without limiting the generality of the foregoing sentence, as soon as practicable after the date of the occurrence of
an Authorized Share Failure, but in no event later than sixty (60) days after the occurrence of such Authorized Share Failure, the Company
shall hold a meeting of its shareholders for the approval of an increase in the number of authorized shares of Ordinary Shares. In connection
with such meeting, the Company shall provide each shareholder with a proxy statement and shall use its best efforts to solicit its shareholders’
approval of such increase in authorized shares of Ordinary Shares and to cause its board of directors to recommend to the shareholders
that they approve such proposal.

2.
ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The Exercise Price and number of Warrant Shares issuable
upon exercise of this Warrant are subject to adjustment from time to time as set forth in this Section 2.


 


(a)
Share Dividends and Splits. Without limiting any provision of Section 4, if the Company, at any time on or after the date
hereof, (i) pays a share dividend on one or more classes of its then outstanding shares of Ordinary Shares or otherwise makes a distribution
on any class of share capital that is payable in shares of Ordinary Shares, (ii) subdivides (by any share split, share dividend, recapitalization
or otherwise) one or more classes of its then outstanding shares of Ordinary Shares into a larger number of shares or (iii) combines (by
combination, reverse share split or otherwise) one or more classes of its then outstanding shares of Ordinary Shares into a smaller number
of shares, then in each such case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares
of Ordinary Shares outstanding immediately before such event and of which the denominator shall be the number of shares of Ordinary Shares
outstanding immediately after such event. Any adjustment made pursuant to clause (i) of this paragraph shall become effective immediately
after the record date for the determination of shareholders entitled to receive such dividend or distribution, and any adjustment pursuant
to clause (ii) or (iii) of this paragraph shall become effective immediately after the effective date of such subdivision or combination.
If any event requiring an adjustment under this paragraph occurs during the period that an Exercise Price is calculated hereunder, then
the calculation of such Exercise Price shall be adjusted appropriately to reflect such event.


 


(b)
[Intentionally Left Blank].


 


(c)
Number of Warrant Shares. Simultaneously with any adjustment to the Exercise Price pursuant to only paragraph (a) of this
Section 2, the number of Warrant Shares that may be purchased upon exercise of this Warrant shall be increased or decreased proportionately,
so that after such adjustment the aggregate Exercise Price payable hereunder for the adjusted number of Warrant Shares shall be the same
as the aggregate Exercise Price in effect immediately prior to such adjustment (without regard to any limitations on exercise contained
herein).


 


(d)
Other Events. In the event that the Company (or any subsidiary) shall take any action to which the provisions hereof are
not strictly applicable, or, if applicable, would not operate to protect the Holder from dilution or if any event occurs of the type contemplated
by the provisions of this Section 2 but not expressly provided for by such provisions (including, without limitation, the granting of
share appreciation rights, phantom share rights or other rights with equity features), then the Company’s board of directors shall
in good faith determine and implement an appropriate adjustment in the Exercise Price and the number of Warrant Shares (if applicable)
so as to protect the rights of the Holder, provided that no such adjustment pursuant to this Section 2(d) will increase the Exercise Price
or decrease the number of Warrant Shares as otherwise determined pursuant to this Section 2, provided further that if the Holder does
not accept such adjustments as appropriately protecting its interests hereunder against such dilution, then the Company’s board
of directors and the Holder shall agree, in good faith, upon an independent investment bank of nationally recognized standing to make
such appropriate adjustments, whose determination shall be final and binding and whose fees and expenses shall be borne by the Company.


 






    4


     


    

 


(e)
Calculations. All calculations under this Section 2 shall be made by rounding to the nearest cent or the nearest 1/100th
of a share, as applicable. The number of shares of Ordinary Shares outstanding at any given time shall not include shares owned or held
by or for the account of the Company, and the disposition of any such shares shall be considered an issue or sale of Ordinary Shares.


 


3.
RIGHTS UPON DISTRIBUTION OF ASSETS. In addition to any adjustments pursuant to Section 2 above, if the Company shall
declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to holders of Ordinary Shares, by way
of return of capital or otherwise (including, without limitation, any distribution of shares or other securities, property or options
by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction, but specifically
excluding cash) (a “Distribution”), at any time after the issuance of this Warrant, then, in each such case, the Holder
shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder
had held the number of shares of Ordinary Shares acquirable upon a complete exercise of this Warrant (without regard to any limitations
on exercise hereof) immediately before the date on which a record is taken for such Distribution, or, if no such record is taken, the
date as of which the record holders of shares of Ordinary Shares are to be determined for the participation in such Distribution.


 


	4.	PURCHASE RIGHTS; FUNDAMENTAL TRANSACTIONS.



 


(a)
Purchase Rights. In addition to any adjustments pursuant to Section 2 above, if at any time while the Warrant remains outstanding
and before the Expiration Date, the Company grants, issues or sells any Options, Convertible Securities or rights to purchase share, warrants,
securities or other property pro rata to the record holders of any class of shares of Ordinary Shares (the “Purchase Rights”),
then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the
Holder could have acquired if the Holder had held the number of shares of Ordinary Shares acquirable upon a complete exercise of this
Warrant (without regard to any limitations on exercise hereof) immediately before the date on which a record is taken for the grant, issuance
or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of Ordinary Shares
are to be determined for the grant, issue or sale of such Purchase Rights.

(b)
Fundamental Transactions. During the term of this Warrant, the Company shall not enter into or be party to a Fundamental
Transaction unless the Successor Entity assumes in writing all of the obligations of the Company under this Warrant in accordance with
the provisions of this Section 4(b) pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved
by the Holder prior to such Fundamental Transaction, such approval not to be unreasonably withheld, conditioned or delayed, including
agreements to deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument
substantially similar in form and substance to this Warrant, including, without limitation, which is exercisable for a corresponding number
of shares of share capital equivalent to the shares of Ordinary Shares acquirable and receivable upon exercise of this Warrant (without
regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price which applies
the exercise price hereunder to such shares of share capital (but taking into account the relative value of the shares of Ordinary Shares
pursuant to such Fundamental Transaction and the value of such shares of share capital, such adjustments to the number of shares of share
capital and such exercise price being for the purpose of protecting the economic value of this Warrant immediately prior to the consummation
of such Fundamental Transaction). Upon the consummation of each Fundamental Transaction, the Successor Entity shall succeed to, and be
substituted for (so that from and after the date of the applicable Fundamental Transaction, the provisions of this Warrant and the other
Transaction Documents referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right
and power of the Company and shall assume all of the obligations of the Company under this Warrant and the other Transaction Documents
with the same effect as if such Successor Entity had been named as the Company herein. Upon consummation of each Fundamental Transaction,
the Successor Entity shall deliver to the Holder confirmation that there shall be issued upon exercise of this Warrant at any time after
the consummation of the applicable Fundamental Transaction, in lieu of the shares of Ordinary Shares (or other securities, cash, assets
or other property (except such items still issuable under Sections 3 and 4(a) above, which shall continue to be receivable thereafter))
issuable upon the exercise of this Warrant prior to the applicable Fundamental Transaction, such shares of publicly traded Ordinary Shares
(or its equivalent) of the Successor Entity (including its Parent Entity) which the Holder would have been entitled to receive upon the
happening of the applicable Fundamental Transaction had this Warrant been exercised immediately prior to the applicable Fundamental Transaction
(without regard to any limitations on the exercise of this Warrant), as adjusted in accordance with the provisions of this Warrant. Notwithstanding
the foregoing, the Holder may elect, at its sole option, by delivery of written notice to the Company to waive this Section 4(b) to permit
the Fundamental Transaction without the assumption of this Warrant. In addition to and not in substitution for any other rights hereunder,
prior to the consummation of each Fundamental Transaction pursuant to which holders of shares of Ordinary Shares are entitled to receive
securities or other assets with respect to or in exchange for shares of Ordinary Shares (a “Corporate Event”), the
Company shall make appropriate provision to insure that the Holder will thereafter have the right to receive upon an exercise of this
Warrant at any time after the consummation of the applicable Fundamental Transaction but prior to the Expiration Date, in lieu of the
shares of the Ordinary Shares (or other securities, cash, assets or other property (except such items still issuable under Sections 3
and 4(a) above, which shall continue to be receivable thereafter)) issuable upon the exercise of the Warrant prior to such Fundamental
Transaction, such shares of share , securities, cash, assets or any other property whatsoever (including warrants or other purchase or
subscription rights) which the Holder would have been entitled to receive upon the happening of the applicable Fundamental Transaction
had this Warrant been exercised immediately prior to the applicable Fundamental Transaction (without regard to any limitations on the
exercise of this Warrant). Provision made pursuant to the preceding sentence shall be in a form and substance reasonably satisfactory
to the Holder.


 






    6


     


    

 


Reserved.


 


(c)
Application. The provisions of this Section 4 shall apply similarly and equally to successive Fundamental Transactions and
Corporate Events and shall be applied as if this Warrant (and any such subsequent warrants) were fully exercisable and without regard
to any limitations on the exercise of this Warrant.


 


5.
NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its certificate
of incorporation, bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution,
issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of
this Warrant, and will at all times in good faith carry out all the provisions of this Warrant and take all action as may be required
to protect the rights of the Holder. Without limiting the generality of the foregoing, the Company (a) shall not increase the par
value of the Ordinary Shares receivable upon the exercise of this Warrant above the Exercise Price then in effect, (b) shall take
all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and non-assessable
shares of Ordinary Shares upon the exercise of this Warrant, and (c) shall, so long as the Warrant is outstanding, take all action necessary
to reserve and keep available out of its authorized and unissued shares of Ordinary Shares, solely for the purpose of effecting the exercise
of the Warrant, the maximum number of shares of Ordinary Shares as shall from time to time be necessary to effect the exercise of the
Warrant then outstanding (without regard to any limitations on exercise).


 


6.
WARRANT HOLDER NOT DEEMED A SHAREHOLDER. Except as otherwise specifically provided herein, the Holder, solely in
its capacity as a holder of this Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of share capital
of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in its capacity
as the Holder of this Warrant, any of the rights of a shareholder of the Company or any right to vote, give or withhold consent to any
corporate action (whether any reorganization, issue of share , reclassification of share , consolidation, merger, conveyance or otherwise),
receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the Holder of the Warrant
Shares which it is then entitled to receive upon the due exercise of this Warrant. In addition, nothing contained in this Warrant shall
be construed as imposing any liabilities on the Holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a
shareholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company. Notwithstanding this
Section 6, the Company shall provide the Holder with copies of the same notices and other information given to the shareholders of the
Company generally, contemporaneously with the giving thereof to the shareholders.


 


7.
REISSUANCE OF WARRANTS.


 


(a)
Transfer of Warrant. If this Warrant is to be transferred, the Holder shall surrender this Warrant to the Company, whereupon
the Company will forthwith issue and deliver upon the order of the Holder a new Warrant (in accordance with Section 7(d)), registered
as the Holder may request, representing the right to purchase the number of Warrant Shares being transferred by the Holder and, if less
than the total number of Warrant Shares then underlying this Warrant is being transferred, a new Warrant (in accordance with Section 7(d))
to the Holder representing the right to purchase the number of Warrant Shares not being transferred.

Company in customary and reasonable form and, in the case of mutilation, upon surrender and cancellation of this Warrant, the Company
shall execute and deliver to the Holder a new Warrant (in accordance with Section 7(d)) representing the right to purchase the Warrant
Shares then underlying this Warrant.


 


(c)

office of the Company, for a new Warrant or Warrants (in accordance with Section 7(d)) representing in the aggregate the right to purchase
the number of Warrant Shares then underlying this Warrant, and each such new Warrant will represent the right to purchase such portion
of such Warrant Shares as is designated by the Holder at the time of such surrender; provided, however, no warrants for fractional shares
of Ordinary Shares shall be given.


 


(d)

other new Warrants issued in connection with such issuance, does not exceed the number of Warrant Shares then underlying this Warrant),
(iii) shall have an issuance date, as indicated on the face of such new Warrant which is the same as the Issuance Date, and (iv) shall
have the same rights and conditions as this Warrant.


 


8.

(a)
The Company shall provide the Holder with prompt written notice of all actions taken pursuant to this Warrant, including in reasonable
detail a description of such action and the reason therefor. Without limiting the generality of the foregoing, the Company will give written

9.

Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the Company has
obtained the written consent of the Holder. No waiver shall be effective unless it is in writing and signed by an authorized representative
of the waiving party.


 


10.
SEVERABILITY. If any provision of this Warrant is prohibited by law or otherwise determined to be invalid or unenforceable
by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended
to apply to the broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision shall
not affect the validity of the remaining provisions of this Warrant so long as this Warrant as so modified continues to express, without
material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability
of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties or
the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith
negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as
close as possible to that of the prohibited, invalid or unenforceable provision(s).


 


11.
GOVERNING LAW. This Warrant shall be governed by and construed and enforced in accordance with, and all questions
concerning the construction, validity, interpretation and performance of this Warrant shall be governed by, the internal laws of the State
of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any
other jurisdictions) that would cause the application of the laws of any jurisdiction other than the State of New York. The Company hereby
irrevocably submits to the exclusive jurisdiction of the federal courts sitting in The City of New York, Borough of Manhattan, for the
adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby
irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction
of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or
proceeding is improper. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted
by law. Nothing contained herein shall be deemed or operate to preclude the Holder from bringing suit or taking other legal action against
the Company in any other jurisdiction to collect on the Company’s obligations to the Holder or to enforce a judgment or other court
ruling in favor of the Holder. If service of process is effected pursuant to the above sentence, such service will be deemed sufficient
under New York law and the Company shall not assert otherwise. Nothing contained herein shall be deemed to limit in any way any right
to serve process in any manner permitted by law. THE COMPANY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE TO, AND AGREES NOT TO

13.
CONSTRUCTION; HEADINGS. This Warrant shall be deemed to be jointly drafted by the Company and the Holder and shall
not be construed against any Person as the drafter hereof. The headings of this Warrant are for convenience of reference and shall not
form part of, or affect the interpretation of, this Warrant. Terms used in this Warrant but defined in the other Transaction Documents
shall have the meanings ascribed to such terms on the Closing Date in such other Transaction Documents unless otherwise consented to in

14.
DISPUTE RESOLUTION. In the case of a dispute as to the determination of the Exercise Price or FMV or the arithmetic
calculation of the Warrant Shares (as the case may be), the Company or the Holder (as the case may be) shall submit the disputed determinations
or arithmetic calculations (as the case may be) via facsimile (a) within two (2) Business Days after receipt of the applicable notice
giving rise to such dispute to the Company or the Holder (as the case may be) or (b) if no notice gave rise to such dispute, at any time
after the Holder learned of the circumstances giving rise to such dispute (including, without limitation, as to whether any issuance or
sale or deemed issuance or sale was an issuance or sale or deemed issuance or sale of Excluded Securities). If the Holder and the Company
are unable to agree upon such determination or calculation (as the case may be) of the Exercise Price, or FMV or the number of Warrant
Shares (as the case may be) within three (3) Business Days of such disputed determination or arithmetic calculation being submitted to

REMEDIES, CHARACTERIZATION, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF. The remedies provided in this Warrant
shall be cumulative and in addition to all other remedies available under this Warrant and the other Transaction Documents, at law or
in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the right of the
Holder to pursue actual damages for any failure by the Company to comply with the terms of this Warrant. The Company covenants to the
Holder that there shall be no characterization concerning this instrument other than as expressly provided herein. Amounts set forth or
provided for herein with respect to payments, exercises and the like (and the computation thereof) shall be the amounts to be received
by the Holder and shall not, except as expressly provided herein, be subject to any other obligation of the Company (or the performance
thereof). The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that
the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened
breach, the holder of this Warrant shall be entitled, in addition to all other available remedies, to an injunction restraining any breach,
without the necessity of showing economic loss and without any bond or other security being required. The Company shall provide all information
and documentation to the Holder that is requested by the Holder to enable the Holder to confirm the Company’s compliance with the
terms and conditions of this Warrant (including, without limitation, compliance with Section 2 hereof). The issuance of shares and certificates
for shares as contemplated hereby upon the exercise of this Warrant shall be made without charge to the Holder or such shares for any
issuance tax or other costs in respect thereof, provided that the Company shall not be required to pay any tax which may be payable in
respect of any transfer involved in the issuance and delivery of any certificate in a name other than the Holder or its agent on its behalf.
