Sonnet
BioTherapeutics Holdings, Inc., a company organized under the laws of Delaware (the “Company”), hereby certifies that,
for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, [  ], 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, at any time or times on or after August 24, 2021 (the “Initial Exercisability
Date”), until exercised in full (the “Termination Date”), [  ] ([  ]) fully paid non-assessable shares of
Common Stock (as defined below), subject to adjustment as provided herein (the “Warrant Shares”). Except as otherwise
defined herein, capitalized terms in this Warrant to Purchase Common Stock (including any Pre-Funded Warrants to Purchase Common Stock
issued in exchange, transfer or replacement hereof, this “Warrant”), shall have the meanings set forth in Section
16. This Warrant is one of the Pre-Funded Warrants to Purchase Common Stock (the “Warrants”) issued pursuant to (i)
that certain Underwriting Agreement, dated as of August 19, 2021 (the “Subscription Date”) by and between the Company
and BTIG, LLC, as representative of the several underwriters named therein, (ii) the Company’s Registration Statement on Form S-1
(File number 333-258092) (the “Registration Statement”) under the Securities Act of 1933, as amended (the “Securities
Act”) and (iii) the Company’s prospectus dated as of August 19, 2021.

 

1.
EXERCISE OF WARRANT.

 

(a)
Mechanics of Exercise. Subject to the terms and conditions hereof (including, without limitation, the limitations set forth in
Section 1(f)), this Warrant may be exercised by the Holder at any time or times on or after the Initial Exercisability Date, in whole
or in part, by delivery (whether via facsimile, electronic mail or otherwise) of a written notice, in the form attached hereto as Annex
A (the “Exercise Notice”), of the Holder’s election to exercise this Warrant. Within one (1) Trading Day
following the delivery of the Exercise Notice, the Holder shall make 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 is being exercised (the “Aggregate
Exercise Price”) in cash by wire transfer of immediately available funds or, if the provisions of Section 1(d) are applicable,
by notifying the Company that this Warrant is being exercised pursuant to a Cashless Exercise (as defined in Section 1(d)). The Holder
shall not be required to deliver the original Warrant in order to effect an exercise hereunder, nor shall any ink-original signature
or medallion guarantee (or other type of guarantee or notarization) with respect to any Exercise Notice be required. Execution and delivery
of the Exercise Notice with respect to less than all of the Warrant Shares shall have the same effect as cancellation of the original
Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Warrant Shares and the Holder shall not
be required to physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder
and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within
three (3) Trading Days of the date on which the final Exercise Notice is delivered to the Company. On or before the first (1st) Trading
Day following the date on which the Holder has delivered the applicable Exercise Notice, the Company shall transmit by facsimile or electronic
mail an acknowledgment of confirmation of receipt of the Exercise Notice, in the form attached to the Exercise Notice, to the Holder
and the Company’s transfer agent (the “Transfer Agent”). So long as the Holder delivers the Aggregate Exercise
Price (or notice of a Cashless Exercise, if applicable) on or prior to the first (1st) Trading Day following the date on which the Exercise
Notice has been delivered to the Company, then on or prior to the earlier of (i) the second (2nd) Trading Day and (ii) the number of
Trading Days comprising the Standard Settlement Period, in each case following the date on which the Exercise Notice has been delivered
to the Company, or, if the Holder does not deliver the Aggregate Exercise Price (or notice of a Cashless Exercise, if applicable) on
or prior to the first (1st) Trading Day following the date on which the Exercise Notice has been delivered to the Company, then on or
prior to the first (1st) Trading Day following the date on which the Aggregate Exercise Price (or notice of a Cashless Exercise) is delivered
(such earlier date, or if later, the earliest day on which the Company is required to deliver Warrant Shares pursuant to this Section
1(a), the “Share Delivery Date”), the Company shall (X) provided that the Transfer Agent is participating in The Depository
Trust Company (“DTC”) Fast Automated Securities Transfer Program, credit such aggregate number of Warrant Shares to
which the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s balance account with DTC through
its Deposit / Withdrawal At Custodian system, or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities
Transfer Program (“FAST”), issue and dispatch by overnight courier to the physical address or email address as specified
in the Exercise Notice, a certificate or evidence of a credit of book-entry shares, registered in the name of the Holder or its designee,
for the number of Warrant Shares to which the Holder is entitled pursuant to such exercise. The Company shall be responsible for all
fees and expenses of the Transfer Agent and all fees and expenses with respect to the issuance of Warrant Shares via DTC, if any, including
without limitation for same day processing. Upon delivery of the Exercise Notice, the Holder shall be deemed for all corporate purposes
to have become the holder of record and beneficial owner of the Warrant Shares with respect to which this Warrant has been exercised,
irrespective of the date such Warrant Shares are credited to the Holder’s DTC account or the date of delivery of the certificates
evidencing such Warrant Shares, as the case may be. If this Warrant is physically delivered to the Company in connection with any exercise
pursuant to this Section 1(a) and the number of Warrant Shares represented by this Warrant submitted for exercise is greater than the
number of Warrant Shares being acquired upon an exercise, then the Company shall as soon as practicable and in no event later than three
(3) Trading 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 issuable 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 down to the nearest
whole number. The Company shall pay any and all transfer, stamp, issuance and similar taxes, costs and expenses (including, without limitation,
fees and expenses of the Transfer Agent) which may be payable with respect to the issuance and delivery of Warrant Shares upon exercise
of this Warrant. The Company’s obligations to issue and deliver Warrant Shares in accordance with the terms and subject to the
conditions hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver
or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or
any setoff, counterclaim, recoupment, limitation or termination; provided, however, that the Company shall not be required
to deliver Warrant Shares with respect to an exercise prior to the Holder’s delivery of the Aggregate Exercise Price (or notice
of a Cashless Exercise) with respect to such exercise.

 

    	 

     

    

 

(b)
Exercise Price. The aggregate exercise price of this Warrant, except for a nominal exercise price of $0.0001 per Warrant Share,
was pre-funded to the Company on or prior to the Initial Exercisability Date and, consequently, no additional consideration (other than
the nominal exercise price of $0.0001 per Warrant Share) shall be required to be paid by the Holder to any Person to effect any exercise
of this Warrant. The Holder shall not be entitled to the return or refund of all, or any portion, of such pre-paid aggregate Exercise
Price under any circumstance or for any reason whatsoever, including in the event this Warrant shall not have been exercised prior to
the Termination Date. The exercise price per share of Common Stock under this Warrant shall be $0.0001, subject to adjustment hereunder
(the “Exercise Price”).

 

(c)
Company’s Failure to Timely Deliver Securities. If either (I) the Company shall fail for any reason or for no reason to
issue to the Holder on or prior to the applicable Share Delivery Date, if (x) the Transfer Agent is not participating in FAST, a certificate
or evidence of a book-entry credit for the number of shares of Common Stock to which the Holder is entitled and register such Common
Stock on the Company’s share register or (y) the Transfer Agent is participating in FAST, to credit the Holder’s balance
account with DTC, for such number of shares of Common Stock to which the Holder is entitled upon the Holder’s exercise of this
Warrant or (II) a registration statement (which may be the Registration Statement) covering the issuance of the Warrant Shares that are
the subject of the Exercise Notice (the “Exercise Notice Warrant Shares”) is not available for the issuance of such
Exercise Notice Warrant Shares and (x) the Company fails to promptly, but in no event later than one (1) Business Day after such registration
statement becomes unavailable, to so notify the Holder and (y) the Company is unable to deliver the Exercise Notice Warrant Shares electronically
without any restrictive legend by crediting such aggregate number of Exercise Notice Warrant Shares to the Holder’s or its designee’s
balance account with DTC through its Deposit / Withdrawal At Custodian system (the event described in the immediately foregoing clause
(II) is hereinafter referred as a “Notice Failure” and together with the event described in clause (I) above, an “Exercise
Failure”), then, in addition to all other remedies available to the Holder, if on or prior to the applicable Share Delivery
Date either (I) if the Transfer Agent is not participating in FAST, the Company shall fail to issue and deliver a certificate or evidence
of a book-entry credit to the Holder and register such shares of Common Stock on the Company’s share register or, if the Transfer
Agent is participating in FAST, credit the Holder’s balance account with DTC for the number of shares of Common Stock to which
the Holder is entitled upon the Holder’s exercise hereunder or pursuant to the Company’s obligation pursuant to clause (ii)
below or (II) if a Notice Failure occurs, and if after such date the Holder is required by its broker to purchase (in an open market
transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction
of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”),
then the Company shall, within three (3) Trading Days after the Holder’s request, (A) pay in cash to the Holder the amount, if
any, by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so
purchased exceeds (y) the amount obtained by multiplying (1) the number of Warrant Shares that the Company was required to deliver to
the Holder in connection with the exercise at issue times (2) the price at which the sell order giving rise to such purchase obligation
was executed, and (B) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Warrant Shares
for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of
shares of Common Stock that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder.
For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted
exercise of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (A)
of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written
notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount
of such loss. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in
equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure
to timely deliver shares of Common Stock upon exercise of the Warrant as required pursuant to the terms hereof. The Company’s current
transfer agent participates in FAST. In the event that the Company changes transfer agents while this Warrant is outstanding, the Company
shall use commercially reasonable efforts to select a transfer agent that participates in FAST. While this Warrant is outstanding, the
Company shall cause its transfer agent to participate in FAST with respect to this Warrant. In addition to the foregoing rights, (i)
if the Company fails to deliver the applicable number of Warrant Shares upon an exercise pursuant to Section 1 by the applicable Share
Delivery Date, then the Holder shall have the right to rescind such exercise in whole or in part and retain and/or have the Company return,
as the case may be, any portion of this Warrant that has not been exercised pursuant to such Exercise Notice; provided that the rescission
of an exercise shall not affect the Company’s obligation to make any payments that have accrued prior to the date of such notice
pursuant to this Section 1(c) or otherwise, and (ii) if a registration statement (which may be the Registration Statement) covering the
issuance of the Warrant Shares that are subject to an Exercise Notice is not available for the issuance of such Exercise Notice Warrant
Shares and the Holder has submitted an Exercise Notice prior to receiving notice of the non-availability of such registration statement
and the Company has not already delivered the Warrant Shares underlying such Exercise Notice electronically without any restrictive legend
by crediting such aggregate number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the Holder’s
or its designee’s balance account with DTC through its Deposit / Withdrawal At Custodian system, the Holder shall have the option,
by delivery of notice to the Company, to (x) rescind such Exercise Notice in whole or in part and retain or have returned, as the case
may be, any portion of this Warrant that has not been exercised pursuant to such Exercise Notice; provided that the rescission of an
Exercise Notice shall not affect the Company’s obligation to make any payments that have accrued prior to the date of such notice
pursuant to this Section 1(c) or otherwise, and/or (y) switch some or all of such Exercise Notice from a cash exercise to a Cashless
Exercise. In addition to the foregoing, if the Company fails for any reason to deliver to the Holder the Warrant Shares subject to an
Exercise Notice by the second Trading Day following the Share Delivery Date, the Company shall pay to the Holder, in cash, as liquidated
damages and not as a penalty, for each $1,000 of Warrant Shares subject to such exercise (based on the Weighted Average Price of the
Common Stock on the date of the applicable Exercise Notice), $10 per Trading Day (increasing to $20 per Trading Day on the fifth Trading
Day after such liquidated damages begin to accrue) for each Trading Day after the second Trading Day following such Share Delivery Date
until such Warrant Shares are delivered or Holder rescinds such exercise.

 

    	 

     

    

 

(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 shares of Common
Stock determined according to the following formula (a “Cashless Exercise”):

 

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=
as applicable: (i) the Weighted Average Price of the Common Stock on the Trading Day immediately preceding the date of the applicable
Exercise Notice if such Exercise Notice is (1) both executed and delivered pursuant to Section 1(a) hereof on a day that is not a Trading
Day or (2) both executed and delivered pursuant to Section 1(a) hereof on a Trading Day prior to the opening of “regular trading
hours” (as defined in Rule 600(b) of Regulation NMS promulgated under the federal securities laws) on such Trading Day, (ii) at
the option of the Holder, either (y) the Weighted Average Price on the Trading Day immediately preceding the date of the applicable Exercise
Notice or (z) the Bid Price of the Common Stock as of the time of the Holder’s execution of the applicable Exercise Notice if such
Exercise Notice is executed during “regular trading hours” on a Trading Day and is delivered within two (2) hours thereafter
(including until two (2) hours after the close of “regular trading hours” on a Trading Day) pursuant to Section 1(a) hereof
or (iii) the Weighted Average Price of the Common Stock on the date of the applicable Exercise Notice if the date of such Exercise Notice
is a Trading Day and such Exercise Notice is both executed and delivered pursuant to Section 1(a) hereof after the close of “regular
trading hours” on such Trading Day.

 

C=
$0.0001, as adjusted hereunder.

 

If
Warrant Shares are issued in such a cashless exercise, the Company acknowledges and agrees that in accordance with Section 3(a)(9) of
the Securities Act, the Warrant Shares shall take on the registered characteristics of the Warrants being exercised, and the holding
period of the Warrants being exercised may be tacked on to the holding period of the Warrant Shares. The Company agrees not to take any
position contrary to this Section 1(d). Without limiting the rights of a Holder to receive Warrant Shares on a “cashless exercise,”
and to receive the cash payments contemplated pursuant to Sections 1(c) and 4(b), in no event will the Company be required to net cash
settle a Warrant exercise.

 

(e)
Disputes. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Warrant
Shares, 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 11.

 

    	 

     

    

 

(f)
Beneficial Ownership. Notwithstanding anything to the contrary contained herein, the Company shall not effect the exercise of
any portion of this Warrant, and the Holder shall not have the right to exercise any portion of this Warrant, pursuant to the terms and
conditions of this Warrant and any such exercise shall be null and void and treated as if never made, to the extent that after giving
effect to such exercise, the Holder together with the other Attribution Parties collectively would beneficially own in excess of 4.99%
(or, upon election of the Holder prior to the issuance of any Warrants, 9.99%) (the “Maximum Percentage”) of the number
of shares of Common Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate
number of shares of Common Stock beneficially owned by the Holder and the other Attribution Parties shall include the number of shares
of Common Stock held by the Holder and all other Attribution Parties plus the number of shares of Common Stock issuable upon exercise
of this Warrant with respect to which the determination of such sentence is being made, but shall exclude the number of shares of Common
Stock which would be issuable upon (A) exercise of the remaining, unexercised portion of this Warrant beneficially owned by the Holder
or any of the other Attribution Parties and (B) exercise or conversion of the unexercised or unconverted portion of any other securities
of the Company (including, without limitation, any convertible notes or convertible preferred stock or warrants, including the other
Warrants) beneficially owned by the Holder or any other Attribution Party subject to a limitation on conversion or exercise analogous
to the limitation contained in this Section 1(f). For purposes of this Section 1(f), beneficial ownership shall be calculated in accordance
with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). For purposes of this Warrant,
in determining the number of outstanding shares of Common Stock the Holder may acquire upon the exercise of this Warrant without exceeding
the Maximum Percentage, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (x) the Company’s
most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q and Current Reports on Form 8-K or other public filing with the
Securities and Exchange Commission (the “SEC”), as the case may be, (y) a more recent public announcement by the Company
or (z) any other written notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding (the
“Reported Outstanding Share Number”). If the Company receives an Exercise Notice from the Holder at a time when the
actual number of outstanding shares of Common Stock is less than the Reported Outstanding Share Number, the Company shall (i) notify
the Holder in writing of the number of shares of Common Stock then outstanding and, to the extent that such Exercise Notice would otherwise
cause the Holder’s beneficial ownership, as determined pursuant to this Section 1(f), to exceed the Maximum Percentage, the Holder
must notify the Company of a reduced number of Warrant Shares to be purchased pursuant to such Exercise Notice (the number of shares
by which such purchase is reduced, the “Reduction Shares”) and (ii) as soon as reasonably practicable, the Company
shall return to the Holder any exercise price paid by the Holder for the Reduction Shares. For any reason at any time, upon the written
or oral request of the Holder, the Company shall within one (1) Business Day confirm orally and in writing or by electronic mail to the
Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be
determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder and
any other Attribution Party since the date as of which the Reported Outstanding Share Number was reported. In the event that the issuance
of Common Stock to the Holder upon exercise of this Warrant results in the Holder and the other Attribution Parties being deemed to beneficially
own, in the aggregate, more than the Maximum Percentage of the number of outstanding shares of Common Stock (as determined under Section
13(d) of the Exchange Act), the number of shares so issued by which the Holder’s and the other Attribution Parties’ aggregate
beneficial ownership exceeds the Maximum Percentage (the “Excess Shares”) shall be deemed null and void and shall
be cancelled ab initio, and the Holder shall not have the power to vote or to transfer the Excess Shares. As soon as reasonably practicable
after the issuance of the Excess Shares has been deemed null and void, the Company shall return to the Holder the exercise price paid
by the Holder for the Excess Shares. Upon delivery of a written notice to the Company, the Holder may from time to time increase or decrease
the Maximum Percentage to any other percentage not in excess of 9.99% as specified in such notice; provided that (i) any such increase
in the Maximum Percentage will not be effective until the sixty-first (61st) day after such notice is delivered to the Company and (ii)
any such increase or decrease will apply only to the Holder and the other Attribution Parties and not to any other holder of Warrants
that is not an Attribution Party of the Holder. For purposes of clarity, the shares of Common Stock issuable pursuant to the terms of
this Warrant in excess of the Maximum Percentage shall not be deemed to be beneficially owned by the Holder for any purpose including
for purposes of Section 13(d) or Rule 16a-1(a)(1) of the Exchange Act. No prior inability to exercise this Warrant pursuant to this paragraph
shall have any effect on the applicability of the provisions of this paragraph with respect to any subsequent determination of exercisability.
The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of
this Section 1(f) to the extent necessary to correct this paragraph or any portion of this paragraph which may be defective or inconsistent
with the intended beneficial ownership limitation contained in this Section 1(f) or to make changes or supplements necessary or desirable
to properly give effect to such limitation. The limitation contained in this paragraph may not be waived and shall apply to a successor
holder of this Warrant.

 

    	 

     

    

 

(g)
Required Reserve Amount. So long as this Warrant remains outstanding, the Company shall at all times keep reserved for issuance
under this Warrant a number of shares of Common Stock at least equal to 100% of the maximum number of shares of Common Stock as shall
be necessary to satisfy the Company’s obligation to issue shares of Common Stock under the Warrants then outstanding (without regard
to any limitations on exercise) (the “Required Reserve Amount”); provided that at no time shall the number
of shares of Common Stock reserved pursuant to this Section 1(g) be reduced other than in connection with any exercise of Warrants or
such other event covered by Section 2(c) below. The Required Reserve Amount (including, without limitation, each increase in the number
of shares so reserved) shall be allocated pro rata among the holders of the Warrants based on the number of shares of Common Stock issuable
upon exercise of Warrants held by each holder thereof on the Issuance Date (without regard to any limitations on exercise) (the “Authorized
Share Allocation”). In the event that a holder shall sell or otherwise transfer any of such holder’s Warrants, each transferee
shall be allocated a pro rata portion of such holder’s Authorized Share Allocation. Any shares of Common Stock reserved and allocated
to any Person which ceases to hold any Warrants shall be allocated to the remaining holders of Warrants, pro rata based on the number
of shares of Common Stock issuable upon exercise of the Warrants then held by such holders thereof (without regard to any limitations
on exercise).

 

(h)
Insufficient Authorized Shares. If at any time while this Warrant remains outstanding the Company does not have a sufficient number
of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance the Required Reserve Amount (an
“Authorized Share Failure”), then the Company shall promptly take all action reasonably necessary to increase the
Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the Required Reserve Amount
for this 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 ninety (90) days after the occurrence of such Authorized Share
Failure, the Company shall hold a meeting of its stockholders for the approval of an increase in the number of authorized shares of Common
Stock. In connection with such meeting, the Company shall provide each stockholder with a proxy statement and shall use its reasonable
best efforts to solicit its stockholders’ approval of such increase in authorized shares of Common Stock and to cause its board
of directors to recommend to the stockholders that they approve such proposal. Notwithstanding the foregoing, if at any such time of
an Authorized Share Failure, the Company is able to obtain the written consent of a majority of the shares of its issued and outstanding
shares of Common Stock to approve the increase in the number of authorized shares of Common Stock, the Company may satisfy this obligation
by obtaining such consent and submitting for filing with the SEC an Information Statement on Schedule 14C.

 

2.
ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The Exercise Price and the number of Warrant Shares shall be adjusted
from time to time as follows:

 

(a)
Intentionally omitted.

 

(b)
Intentionally omitted.

 

(c)
Adjustment Upon Subdivision or Combination of Common Stock. If the Company at any time on or after the Subscription Date subdivides
(by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into
a greater number of shares, the Exercise Price in effect immediately prior to such subdivision will be proportionately reduced and the
number of Warrant Shares will be proportionately increased. If the Company at any time on or after the Subscription Date combines (by
combination, reverse stock split or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of
shares, the Exercise Price in effect immediately prior to such combination will be proportionately increased and the number of Warrant
Shares will be proportionately decreased. Any adjustment under this Section 2(c) shall become effective at the close of business on the
date the subdivision or combination becomes effective.

 

3.
RIGHTS UPON DISTRIBUTION OF ASSETS. In addition to any adjustments pursuant to Section 2 above, if, on or after the Subscription
Date and on or prior to the Termination Date, the Company shall declare or make any dividend or other distribution of its assets (or
rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including, without limitation,
any distribution of cash, stock or other securities, property, options, evidence of indebtedness or any other assets by way of a dividend,
spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (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 Common Stock acquirable
upon complete exercise of this Warrant (without regard to any limitations or restrictions on exercise of this Warrant, including without
limitation, the Maximum Percentage) 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 Common Stock are to be determined for the participation in such Distribution
(provided, however, that to the extent that the Holder’s right to participate in any such Distribution would result
in the Holder and the other Attribution Parties exceeding the Maximum Percentage, then the Holder shall not be entitled to participate
in such Distribution to such extent (and shall not be entitled to beneficial ownership of such shares of Common Stock as a result of
such Distribution (and beneficial ownership) to such extent) and the portion of such Distribution shall be held in abeyance for the benefit
of the Holder until such time or times as its right thereto would not result in the Holder and the other Attribution Parties exceeding
the Maximum Percentage, at which time or times the Holder shall be granted such Distribution (and any Distributions declared or made
on such initial Distribution or on any subsequent Distribution held similarly in abeyance) to the same extent as if there had been no
such limitation).

 

    	 

     

    

 

4.
PURCHASE RIGHTS; FUNDAMENTAL TRANSACTIONS.

 

(a)
Purchase Rights. In addition to any adjustments pursuant to Section 2 above, if at any time on or after the Subscription Date
and on or prior to the Termination Date the Company grants, issues or sells any Options, Convertible Securities or rights to purchase
stock, warrants, securities or other property pro rata to the record holders of any class of Common Stock (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 Common Stock acquirable upon complete exercise of this Warrant
(without regard to any limitations or restrictions on exercise of this Warrant, including without limitation, the Maximum Percentage)
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 Common Stock are to be determined for the grant, issuance or sale of such Purchase
Rights (provided, however, that to the extent that the Holder’s right to participate in any such Purchase Right would
result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, then the Holder shall not be entitled to participate
in such Purchase Right to such extent (and shall not be entitled to beneficial ownership of such Common Stock as a result of such Purchase
Right (and beneficial ownership) to such extent) and such Purchase Right to such extent shall be held in abeyance for the benefit of
the Holder until such time or times as its right thereto would not result in the Holder and the other Attribution Parties exceeding the
Maximum Percentage, at which time or times the Holder shall be granted such right (and any Purchase Right granted, issued or sold on
such initial Purchase Right or on any subsequent Purchase Right to be held similarly in abeyance) to the same extent as if there had
been no such limitation).

 

(b)
Fundamental Transaction. 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), 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 capital stock equivalent to the shares of Common Stock 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 capital stock (but taking into account the relative value of the shares of Common Stock
pursuant to such Fundamental Transaction and the value of such shares of capital stock, such adjustments to the number of shares of capital
stock 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 the Company (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 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 Common Stock (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 common stock (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, and without
limiting Section 1(f) hereof, 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 Common Stock are entitled
to receive securities or other assets with respect to or in exchange for shares of Common Stock (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 Termination Date, in lieu
of the shares of the Common Stock (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 stock, securities, cash, assets or any other property whatsoever (including warrants or other purchase or
subscription rights) (collectively, the “Corporate Event Consideration”) 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). The provision made pursuant to the preceding
sentence shall be in a form and substance reasonably satisfactory to the Requisite Holders. The provisions of this Section 4(b) shall
apply similarly and equally to successive Fundamental Transactions and Corporate Events.

 

    	 

     

    

 

5.
NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation
or Bylaws, or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issuance 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 of the provisions of this Warrant and take all action as may be required to protect

as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Common

then outstanding (without regard to any limitations on exercise).

 

6.
WARRANT HOLDER NOT DEEMED A STOCKHOLDER. Except as otherwise specifically provided herein, the Holder, solely in such Person’s
capacity as a holder of this Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of capital stock of
the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in such Person’s
capacity as the Holder of this Warrant, any of the rights of a stockholder of the Company or any right to vote, give or withhold consent
to any corporate action (whether any reorganization, issue of stock, reclassification of stock, 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 such Person 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 stockholder 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
stockholders of the Company generally, contemporaneously with the giving thereof to the stockholders.

GOVERNING LAW; JURISDICTION; JURY TRIAL. 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 jurisdictions other than the State of New

in favor of the Holder. If either party shall commence an action, suit or proceeding to enforce any provisions of this Warrant, the prevailing
party in such action, suit or proceeding shall be reimbursed by the other party for their reasonable attorneys’ fees and other
costs and expenses incurred with the investigation, preparation and prosecution of such action or proceeding. THE COMPANY HEREBY IRREVOCABLY
WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION

and the Company shall submit the disputed determinations or arithmetic calculations via facsimile or electronic mail within two (2) Business
Days of receipt of the Exercise Notice or other event giving rise to such dispute, as the case may be, to the Holder. If the Holder and
the Company are unable to agree upon such determination or calculation of the Exercise Price or the Warrant Shares within three (3) Business
Days of such disputed determination or arithmetic calculation being submitted to the Holder, then the Company shall, within two (2) Business
Days submit via facsimile or electronic mail (a) the disputed determination of the Exercise Price to an independent, reputable investment
bank selected by the Holder and approved by the Company, such approval not to be unreasonably withheld, conditioned or delayed or (b)

at its expense the investment bank or the accountant, as the case may be, to perform the determinations or calculations and notify the
Company and the Holder of the results no later than ten (10) Business Days from the time it receives the disputed determinations or calculations.
Such investment bank’s or accountant’s determination or calculation, as the case may be, shall be binding upon all parties
absent demonstrable error.

 

12.
REMEDIES, 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 any 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 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.

14.
SEVERABILITY; CONSTRUCTION; HEADINGS. 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). 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.

TO PURCHASE COMMON STOCK

 

Warrant
No.: [  ]

Number
of Shares of Common Stock: [  ]

Date
of Issuance: August 24, 2021 (“Issuance Date”)

 

Sonnet
BioTherapeutics Holdings, Inc., a company organized under the laws of Delaware (the “Company”), hereby certifies that,
for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, [  ], 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, at any time or times on or after August 24, 2021 (the “Initial
Exercisability Date”), but not after 11:59 p.m., New York time, on the Expiration Date, (as defined below), [  ]
([  ]) fully paid non-assessable shares of Common Stock (as defined below), subject to adjustment as provided herein (the “Warrant
Shares”). Except as otherwise defined herein, capitalized terms in this Warrant to Purchase Common Stock (including any Warrants
to Purchase Common Stock issued in exchange, transfer or replacement hereof, this “Warrant”), shall have the meanings
set forth in Section 16. This Warrant is one of the Warrants to Purchase Common Stock (the “Warrants”) issued pursuant
to (i) that certain Underwriting Agreement, dated as of August 19, 2021 (the “Subscription Date”) by and between the
Company and BTIG, LLC, as representative of the several underwriters named therein, (ii) the Company’s Registration Statement on
Form S-1 (File number 333-258092) under the Securities Act of 1933, as amended (the “Registration Statement”) and
(iii) the Company’s prospectus dated as of August 19, 2021.

 

1.
EXERCISE OF WARRANT.

 

(a)
Mechanics of Exercise. Subject to the terms and conditions hereof (including, without limitation, the limitations set forth in
Section 1(f)), this Warrant may be exercised by the Holder at any time or times on or after the Initial Exercisability Date, in whole
or in part, by delivery (whether via facsimile, electronic mail 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. Within one (1) Trading Day
following the delivery of the Exercise Notice, the Holder shall make 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 is being exercised (the “Aggregate
Exercise Price”) in cash by wire transfer of immediately available funds or, if the provisions of Section 1(d) are applicable,
by notifying the Company that this Warrant is being exercised pursuant to a Cashless Exercise (as defined in Section 1(d)). The Holder
shall not be required to deliver the original Warrant in order to effect an exercise hereunder, nor shall any ink-original signature
or medallion guarantee (or other type of guarantee or notarization) with respect to any Exercise Notice be required. Execution and delivery
of the Exercise Notice with respect to less than all of the Warrant Shares shall have the same effect as cancellation of the original
Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Warrant Shares and the Holder shall not
be required to physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder
and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within
three (3) Trading Days of the date on which the final Exercise Notice is delivered to the Company. On or before the first (1st) Trading
Day following the date on which the Holder has delivered the applicable Exercise Notice, the Company shall transmit by facsimile or electronic
mail an acknowledgment of confirmation of receipt of the Exercise Notice, in the form attached to the Exercise Notice, to the Holder
and the Transfer Agent. So long as the Holder delivers the Aggregate Exercise Price (or notice of a Cashless Exercise, if applicable)
on or prior to the first (1st) Trading Day following the date on which the Exercise Notice has been delivered to the Company, then on
or prior to the earlier of (i) the second (2nd) Trading Day and (ii) the number of Trading Days comprising the Standard Settlement
Period, in each case following the date on which the Exercise Notice has been delivered to the Company, or, if the Holder does not deliver
the Aggregate Exercise Price (or notice of a Cashless Exercise, if applicable) on or prior to the first (1st) Trading Day following the
date on which the Exercise Notice has been delivered to the Company, then on or prior to the first (1st) Trading Day following the date
on which the Aggregate Exercise Price (or notice of a Cashless Exercise) is delivered (such earlier date, or if later, the earliest day
on which the Company is required to deliver Warrant Shares pursuant to this Section 1(a), the “Share Delivery Date”),
the Company shall (X) provided that the Transfer Agent is participating in the DTC Fast Automated Securities Transfer Program (“FAST”),
credit such aggregate number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the Holder’s or its
designee’s balance account with DTC through its Deposit / Withdrawal At Custodian system, or (Y) if the Transfer Agent is not participating
in FAST, issue and dispatch by overnight courier to the physical address or email address as specified in the Exercise Notice, a certificate
or evidence of a credit of book-entry shares, registered in the name of the Holder or its designee, for the number of Warrant Shares
to which the Holder is entitled pursuant to such exercise. The Company shall be responsible for all fees and expenses of the Transfer
Agent and all fees and expenses with respect to the issuance of Warrant Shares via DTC, if any, including without limitation for same
day processing. Upon delivery of the Exercise Notice, the Holder shall be deemed for all corporate purposes to have become the holder
of record and beneficial owner of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date
such Warrant Shares are credited to the Holder’s DTC account or the date of delivery of the certificates evidencing such Warrant
Shares, as the case may be. If this Warrant is physically delivered to the Company in connection with any exercise pursuant to this Section
1(a) and the number of Warrant Shares represented by this Warrant submitted for exercise is greater than the number of Warrant Shares
being acquired upon an exercise, then the Company shall as soon as practicable and in no event later than three (3) Trading 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 issuable 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 down to the nearest whole number. The
Company shall pay any and all transfer, stamp, issuance and similar taxes, costs and expenses (including, without limitation, fees and
expenses of the Transfer Agent) which may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of this
Warrant. The Company’s obligations to issue and deliver Warrant Shares in accordance with the terms and subject to the conditions
hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver or consent
with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff,
counterclaim, recoupment, limitation or termination; provided, however, that the Company shall not be required to deliver Warrant
Shares with respect to an exercise prior to the Holder’s delivery of the Aggregate Exercise Price (or notice of a Cashless Exercise)
with respect to such exercise.

 

    	 

    	 

    

 

(b)
Exercise Price. For purposes of this Warrant, “Exercise Price” means $0.85 per share, subject to adjustment
as provided herein.

 

(c)
Company’s Failure to Timely Deliver Securities. If either (I) the Company shall fail for any reason or for no reason to
issue to the Holder on or prior to the applicable Share Delivery Date, if (x) the Transfer Agent is not participating in FAST, a certificate
or evidence of a book-entry credit for the number of shares of Common Stock to which the Holder is entitled and register such Common
Stock on the Company’s share register or (y) the Transfer Agent is participating in FAST, to credit the Holder’s balance
account with DTC, for such number of shares of Common Stock to which the Holder is entitled upon the Holder’s exercise of this
Warrant or (II) a registration statement (which may be the Registration Statement) covering the issuance of the Warrant Shares that are
the subject of the Exercise Notice (the “Exercise Notice Warrant Shares”) is not available for the issuance of such
Exercise Notice Warrant Shares and (x) the Company fails to promptly, but in no event later than one (1) Business Day after such registration
statement becomes unavailable, to so notify the Holder and (y) the Company is unable to deliver the Exercise Notice Warrant Shares electronically
without any restrictive legend by crediting such aggregate number of Exercise Notice Warrant Shares to the Holder’s or its designee’s
balance account with DTC through its Deposit / Withdrawal At Custodian system (the event described in the immediately foregoing clause
(II) is hereinafter referred as a “Notice Failure” and together with the event described in clause (I) above, an “Exercise
Failure”), then, in addition to all other remedies available to the Holder, if on or prior to the applicable Share Delivery
Date either (I) if the Transfer Agent is not participating in FAST, the Company shall fail to issue and deliver a certificate or evidence
of a book-entry credit to the Holder and register such shares of Common Stock on the Company’s share register or, if the Transfer
Agent is participating in FAST, credit the Holder’s balance account with DTC for the number of shares of Common Stock to which
the Holder is entitled upon the Holder’s exercise hereunder or pursuant to the Company’s obligation pursuant to clause (ii)
below or (II) if a Notice Failure occurs, and if after such date the Holder is required by its broker to purchase (in an open market
transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction
of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”),
then the Company shall, within three (3) Trading Days after the Holder’s request, (A) pay in cash to the Holder the amount, if
any, by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so
purchased exceeds (y) the amount obtained by multiplying (1) the number of Warrant Shares that the Company was required to deliver to
the Holder in connection with the exercise at issue times (2) the price at which the sell order giving rise to such purchase obligation
was executed, and (B) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Warrant Shares
for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of
shares of Common Stock that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder.
For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted
exercise of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (A)
of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written
notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount
of such loss. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in
equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure
to timely deliver shares of Common Stock upon exercise of the Warrant as required pursuant to the terms hereof. The Company’s current
transfer agent participates in FAST. In the event that the Company changes transfer agents while this Warrant is outstanding, the Company
shall use commercially reasonable efforts to select a transfer agent that participates in FAST. While this Warrant is outstanding, the
Company shall cause its transfer agent to participate in FAST with respect to this Warrant. In addition to the foregoing rights, (i)
if the Company fails to deliver the applicable number of Warrant Shares upon an exercise pursuant to Section 1 by the applicable Share
Delivery Date, then the Holder shall have the right to rescind such exercise in whole or in part and retain and/or have the Company return,
as the case may be, any portion of this Warrant that has not been exercised pursuant to such Exercise Notice; provided that the rescission
of an exercise shall not affect the Company’s obligation to make any payments that have accrued prior to the date of such notice
pursuant to this Section 1(c) or otherwise, and (ii) if a registration statement (which may be the Registration Statement) covering the
issuance of the Warrant Shares that are subject to an Exercise Notice is not available for the issuance of such Exercise Notice Warrant
Shares and the Holder has submitted an Exercise Notice prior to receiving notice of the non-availability of such registration statement
and the Company has not already delivered the Warrant Shares underlying such Exercise Notice electronically without any restrictive legend
by crediting such aggregate number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the Holder’s
or its designee’s balance account with DTC through its Deposit / Withdrawal At Custodian system, the Holder shall have the option,
by delivery of notice to the Company, to (x) rescind such Exercise Notice in whole or in part and retain or have returned, as the case
may be, any portion of this Warrant that has not been exercised pursuant to such Exercise Notice; provided that the rescission of an
Exercise Notice shall not affect the Company’s obligation to make any payments that have accrued prior to the date of such notice
pursuant to this Section 1(c) or otherwise, and/or (y) switch some or all of such Exercise Notice from a cash exercise to a Cashless
Exercise. In addition to the foregoing, if the Company fails for any reason to deliver to the Holder the Warrant Shares subject to an
Exercise Notice by the second Trading Day following the Share Delivery Date, the Company shall pay to the Holder, in cash, as liquidated
damages and not as a penalty, for each $1,000 of Warrant Shares subject to such exercise (based on the Weighted Average Price of the
Common Stock on the date of the applicable Exercise Notice), $10 per Trading Day (increasing to $20 per Trading Day on the fifth Trading
Day after such liquidated damages begin to accrue) for each Trading Day after the second Trading Day following such Share Delivery Date
until such Warrant Shares are delivered or Holder rescinds such exercise.

 

    	 

    	 

    

 

(d)
Cashless Exercise. Notwithstanding anything contained herein to the contrary, if a registration statement (which may be the Registration
Statement) covering the issuance of the Exercise Notice Warrant Shares is not available for the issuance of such Exercise Notice Warrant
Shares, 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 shares of Common Stock determined according to the following formula (a “Cashless Exercise”):

 

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
= as applicable: (i) the Weighted Average Price of the Common Stock on the Trading Day immediately preceding the date of the applicable
Exercise Notice if such Exercise Notice is (1) both executed and delivered pursuant to Section 1(a) hereof on a day that is not a Trading
Day or (2) both executed and delivered pursuant to Section 1(a) hereof on a Trading Day prior to the opening of “regular trading
hours” (as defined in Rule 600(b) of Regulation NMS promulgated under the federal securities laws) on such Trading Day, (ii) at
the option of the Holder, either (y) the Weighted Average Price on the Trading Day immediately preceding the date of the applicable Exercise
Notice or (z) the Bid Price of the Common Stock as of the time of the Holder’s execution of the applicable Exercise Notice if such
Exercise Notice is executed during “regular trading hours” on a Trading Day and is delivered within two (2) hours thereafter
(including until two (2) hours after the close of “regular trading hours” on a Trading Day) pursuant to Section 1(a) hereof
or (iii) the Weighted Average Price of the Common Stock on the date of the applicable Exercise Notice if the date of such Exercise Notice
is a Trading Day and such Exercise Notice is both executed and delivered pursuant to Section 1(a) hereof after the close of “regular
trading hours” on such Trading Day.

 

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

 

If
Warrant Shares are issued in such a cashless exercise, the Company acknowledges and agrees that in accordance with Section 3(a)(9) of
the Securities Act of 1933, as amended, the Warrant Shares shall take on the registered characteristics of the Warrants being exercised,
and the holding period of the Warrants being exercised may be tacked on to the holding period of the Warrant Shares. The Company agrees
not to take any position contrary to this Section 1(d). Without limiting the rights of a Holder to receive Warrant Shares on a “cashless
exercise,” and to receive the cash payments contemplated pursuant to Sections 1(c) and 4(b), in no event will the Company be required
to net cash settle a Warrant exercise.

 

(e)
Disputes. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Warrant
Shares, 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 11.

 

    	 

    	 

    

 

(f)
Beneficial Ownership. Notwithstanding anything to the contrary contained herein, the Company shall not effect the exercise of
any portion of this Warrant, and the Holder shall not have the right to exercise any portion of this Warrant, pursuant to the terms and
conditions of this Warrant and any such exercise shall be null and void and treated as if never made, to the extent that after giving
effect to such exercise, the Holder together with the other Attribution Parties collectively would beneficially own in excess of 4.99%
(or, upon election by a Holder prior to the issuance of any Warrants, 9.99%) (the “Maximum Percentage”) of the number
of shares of Common Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate
number of shares of Common Stock beneficially owned by the Holder and the other Attribution Parties shall include the number of shares
of Common Stock held by the Holder and all other Attribution Parties plus the number of shares of Common Stock issuable upon exercise
of this Warrant with respect to which the determination of such sentence is being made, but shall exclude the number of shares of Common
Stock which would be issuable upon (A) exercise of the remaining, unexercised portion of this Warrant beneficially owned by the Holder
or any of the other Attribution Parties and (B) exercise or conversion of the unexercised or unconverted portion of any other securities
of the Company (including, without limitation, any convertible notes or convertible preferred stock or warrants, including the other
Warrants) beneficially owned by the Holder or any other Attribution Party subject to a limitation on conversion or exercise analogous
to the limitation contained in this Section 1(f). For purposes of this Section 1(f), beneficial ownership shall be calculated in accordance
with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “1934 Act”). For purposes of this Warrant,
in determining the number of outstanding shares of Common Stock the Holder may acquire upon the exercise of this Warrant without exceeding
the Maximum Percentage, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (x) the Company’s
most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q and Current Reports on Form 8-K or other public filing with the
Securities and Exchange Commission (the “SEC”), as the case may be, (y) a more recent public announcement by the Company
or (z) any other written notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding (the
“Reported Outstanding Share Number”). If the Company receives an Exercise Notice from the Holder at a time when the
actual number of outstanding shares of Common Stock is less than the Reported Outstanding Share Number, the Company shall (i) notify
the Holder in writing of the number of shares of Common Stock then outstanding and, to the extent that such Exercise Notice would otherwise
cause the Holder’s beneficial ownership, as determined pursuant to this Section 1(f), to exceed the Maximum Percentage, the Holder
must notify the Company of a reduced number of Warrant Shares to be purchased pursuant to such Exercise Notice (the number of shares
by which such purchase is reduced, the “Reduction Shares”) and (ii) as soon as reasonably practicable, the Company
shall return to the Holder any exercise price paid by the Holder for the Reduction Shares. For any reason at any time, upon the written
or oral request of the Holder, the Company shall within one (1) Business Day confirm orally and in writing or by electronic mail to the
Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be
determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder and
any other Attribution Party since the date as of which the Reported Outstanding Share Number was reported. In the event that the issuance
of Common Stock to the Holder upon exercise of this Warrant results in the Holder and the other Attribution Parties being deemed to beneficially
own, in the aggregate, more than the Maximum Percentage of the number of outstanding shares of Common Stock (as determined under Section
13(d) of the 1934 Act), the number of shares so issued by which the Holder’s and the other Attribution Parties’ aggregate
beneficial ownership exceeds the Maximum Percentage (the “Excess Shares”) shall be deemed null and void and shall
be cancelled ab initio and any portion of this Warrant so exercised shall be reinstated, and the Holder shall not have the power to vote
or to transfer the Excess Shares. As soon as reasonably practicable after the issuance of the Excess Shares has been deemed null and
void, the Company shall return to the Holder the exercise price paid by the Holder for the Excess Shares. Upon delivery of a written
notice to the Company, the Holder may from time to time increase or decrease the Maximum Percentage to any other percentage not in excess
of 9.99% as specified in such notice; provided that (i) any such increase in the Maximum Percentage will not be effective until the sixty-first
(61st) day after such notice is delivered to the Company and (ii) any such increase or decrease will apply only to the Holder
and the other Attribution Parties and not to any other holder of Warrants that is not an Attribution Party of the Holder. For purposes
of clarity, the shares of Common Stock issuable pursuant to the terms of this Warrant in excess of the Maximum Percentage shall not be
deemed to be beneficially owned by the Holder for any purpose including for purposes of Section 13(d) or Rule 16a-1(a)(1) of the 1934
Act. No prior inability to exercise this Warrant pursuant to this paragraph shall have any effect on the applicability of the provisions
of this paragraph with respect to any subsequent determination of exercisability. The provisions of this paragraph shall be construed
and implemented in a manner otherwise than in strict conformity with the terms of this Section 1(f) to the extent necessary to correct
this paragraph or any portion of this paragraph which may be defective or inconsistent with the intended beneficial ownership limitation
contained in this Section 1(f) or to make changes or supplements necessary or desirable to properly give effect to such limitation. The
limitation contained in this paragraph may not be waived and shall apply to a successor holder of this Warrant.

  

(g)
Required Reserve Amount. So long as this Warrant remains outstanding, the Company shall at all times keep reserved for issuance
under this Warrant a number of shares of Common Stock at least equal to 100% of the maximum number of shares of Common Stock as shall
be necessary to satisfy the Company’s obligation to issue shares of Common Stock under the Warrants then outstanding (without regard
to any limitations on exercise) (the “Required Reserve Amount”); provided that at no time shall the number
of shares of Common Stock reserved pursuant to this Section 1(g) be reduced other than in connection with any exercise of Warrants or
such other event covered by Section 2(c) below. The Required Reserve Amount (including, without limitation, each increase in the number
of shares so reserved) shall be allocated pro rata among the holders of the Warrants based on the number of shares of Common Stock issuable
upon exercise of Warrants held by each holder thereof on the Issuance Date (without regard to any limitations on exercise) (the “Authorized
Share Allocation”). In the event that a holder shall sell or otherwise transfer any of such holder’s Warrants, each transferee
shall be allocated a pro rata portion of such holder’s Authorized Share Allocation. Any shares of Common Stock reserved and allocated
to any Person which ceases to hold any Warrants shall be allocated to the remaining holders of Warrants, pro rata based on the number
of shares of Common Stock issuable upon exercise of the Warrants then held by such holders thereof (without regard to any limitations
on exercise).

 

    	 

    	 

    

 

(h)
Insufficient Authorized Shares. If at any time while this Warrant remains outstanding the Company does not have a sufficient number
of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance the Required Reserve Amount (an
“Authorized Share Failure”), then the Company shall promptly take all action reasonably necessary to increase the
Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the Required Reserve Amount
for this 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 ninety (90) days after the occurrence of such Authorized Share
Failure, the Company shall hold a meeting of its stockholders for the approval of an increase in the number of authorized shares of Common
Stock. In connection with such meeting, the Company shall provide each stockholder with a proxy statement and shall use its reasonable
best efforts to solicit its stockholders’ approval of such increase in authorized shares of Common Stock and to cause its board
of directors to recommend to the stockholders that they approve such proposal. Notwithstanding the foregoing, if at any such time of
an Authorized Share Failure, the Company is able to obtain the written consent of a majority of the shares of its issued and outstanding
shares of Common Stock to approve the increase in the number of authorized shares of Common Stock, the Company may satisfy this obligation
by obtaining such consent and submitting for filing with the SEC an Information Statement on Schedule 14C.

 

2.
ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The Exercise Price and the number of Warrant Shares shall be adjusted
from time to time as follows:

 

(a)
Intentionally omitted.

 

(b)
Voluntary Adjustment By Company. Unless prohibited by the rules of the Principal Market, the Company may at any time during the
term of this Warrant reduce the then current Exercise Price to any amount and for any period of time deemed appropriate by the Board
of Directors of the Company.

 

(c)
Adjustment Upon Subdivision or Combination of Common Stock. If the Company at any time on or after the Subscription Date subdivides
(by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into
a greater number of shares, the Exercise Price in effect immediately prior to such subdivision will be proportionately reduced and the
number of Warrant Shares will be proportionately increased. If the Company at any time on or after the Subscription Date combines (by
combination, reverse stock split or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of
shares, the Exercise Price in effect immediately prior to such combination will be proportionately increased and the number of Warrant
Shares will be proportionately decreased. Any adjustment under this Section 2(c) shall become effective at the close of business on the
date the subdivision or combination becomes effective.

 

3.
RIGHTS UPON DISTRIBUTION OF ASSETS. In addition to any adjustments pursuant to Section 2 above, if, on or after the Subscription
Date and on or prior to the Expiration Date, the Company shall declare or make any dividend or other distribution of its assets (or rights
to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including, without limitation,
any distribution of cash, stock or other securities, property, options, evidence of indebtedness or any other assets by way of a dividend,
spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (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 Common Stock acquirable
upon complete exercise of this Warrant (without regard to any limitations or restrictions on exercise of this Warrant, including without
limitation, the Maximum Percentage) 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 Common Stock are to be determined for the participation in such Distribution
(provided, however, that to the extent that the Holder’s right to participate in any such Distribution would result in the Holder
and the other Attribution Parties exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in such Distribution
to such extent (and shall not be entitled to beneficial ownership of such shares of Common Stock as a result of such Distribution (and
beneficial ownership) to such extent) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder until
such time or times as its right thereto would not result in the Holder and the other Attribution Parties exceeding the Maximum Percentage,
at which time or times the Holder shall be granted such Distribution (and any Distributions declared or made on such initial Distribution
or on any subsequent Distribution held similarly in abeyance) to the same extent as if there had been no such limitation).

 

    	 

    	 

    

 

4.
PURCHASE RIGHTS; FUNDAMENTAL TRANSACTIONS.

 

(a)
Purchase Rights. In addition to any adjustments pursuant to Section 2 above, if at any time on or after the Subscription Date
and on or prior to the Expiration Date the Company grants, issues or sells any Options, Convertible Securities or rights to purchase
stock, warrants, securities or other property pro rata to the record holders of any class of Common Stock (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 Common Stock acquirable upon complete exercise of this Warrant
(without regard to any limitations or restrictions on exercise of this Warrant, including without limitation, the Maximum Percentage)
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 Common Stock are to be determined for the grant, issuance or sale of such Purchase
Rights (provided, however, that to the extent that the Holder’s right to participate in any such Purchase Right would result
in the Holder and the other Attribution Parties exceeding the Maximum Percentage, then the Holder shall not be entitled to participate
in such Purchase Right to such extent (and shall not be entitled to beneficial ownership of such Common Stock as a result of such Purchase
Right (and beneficial ownership) to such extent) and such Purchase Right to such extent shall be held in abeyance for the benefit of
the Holder until such time or times as its right thereto would not result in the Holder and the other Attribution Parties exceeding the
Maximum Percentage, at which time or times the Holder shall be granted such right (and any Purchase Right granted, issued or sold on
such initial Purchase Right or on any subsequent Purchase Right to be held similarly in abeyance) to the same extent as if there had
been no such limitation).

 

(b)
Fundamental Transaction. 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), 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 capital stock equivalent to the shares of Common Stock 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 capital stock (but taking into account the relative value of the shares of Common Stock
pursuant to such Fundamental Transaction and the value of such shares of capital stock, such adjustments to the number of shares of capital
stock 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 the Company (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 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 Common Stock (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 common stock (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, and without
limiting Section 1(f) hereof, 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 Common Stock are entitled
to receive securities or other assets with respect to or in exchange for shares of Common Stock (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 Common Stock (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 stock, securities, cash, assets or any other property whatsoever (including warrants or other purchase or
subscription rights) (collectively, the “Corporate Event Consideration”) 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). The provision made pursuant to the preceding
sentence shall be in a form and substance reasonably satisfactory to the Requisite Holders. The provisions of this Section 4(b) shall
apply similarly and equally to successive Fundamental Transactions and Corporate Events. Notwithstanding the foregoing, in the event
of a Change of Control (other than a Change of Control which was not approved by the Board of Directors, as to which this right shall
not apply), at the request of the Holder delivered before the 30th day after such Change of Control, the Company (or the Successor Entity)
shall purchase this Warrant from the Holder by paying to the Holder, within five (5) Business Days after such request (or, if later,
on the effective date of the Change of Control), an amount equal to the Black Scholes Value of the remaining unexercised portion of this
Warrant on the effective date of such Change of Control, payable in cash; provided, however, if such Change of Control
is not within the Company’s control, including not approved by the Company’s Board of Directors, the Holder shall only be
entitled to receive from the Company or any Successor Entity, as of the date of consummation of such Change of Control, the same type
or form of consideration (and in the same proportion), at the Black Scholes Value of the unexercised portion of this Warrant, that is
being offered and paid to the holders of Common Stock in connection with such Change of Control, whether that consideration be in the
form of cash, stock or any combination thereof, or whether the holders of Common Stock are given the choice to receive from among alternative
forms of consideration in connection with such Fundamental Transaction; provided, further, that if the holders of Common Stock are not
offered any consideration in such Change of Control, the holders of Common Stock are deemed to be issued shares of Common Stock in such
Change of Control. The payment of the Black Scholes Value will be made pursuant to instructions delivered by the Holder to the Company
within five (5) Business Days of the Holder’s election (or, if later, on the effective date of the Change of Control).

 

    	 

    	 

    

 

5.
NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation
or Bylaws, or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issuance 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 of 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 (i) shall not increase the par value of any shares
of Common Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect, (ii) shall take all such actions
as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Common
Stock upon the exercise of this Warrant, and (iii) shall, so long as any of the Warrants are outstanding, take all action necessary to
reserve and keep available out of its authorized and unissued shares of Common Stock, solely for the purpose of effecting the exercise
of the Warrants, the number of shares of Common Stock as shall from time to time be necessary to effect the exercise of the Warrants
then outstanding (without regard to any limitations on exercise).

 

6.
WARRANT HOLDER NOT DEEMED A STOCKHOLDER. Except as otherwise specifically provided herein, the Holder, solely in such Person’s
capacity as a holder of this Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of capital stock of
the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in such Person’s
capacity as the Holder of this Warrant, any of the rights of a stockholder of the Company or any right to vote, give or withhold consent
to any corporate action (whether any reorganization, issue of stock, reclassification of stock, 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 such Person 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 stockholder 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
stockholders of the Company generally, contemporaneously with the giving thereof to the stockholders.

9.
AMENDMENT AND WAIVER. Except as otherwise provided herein, the provisions of this Warrant may be amended or waived and the 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.

 

10.
GOVERNING LAW; JURISDICTION; JURY TRIAL. 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 jurisdictions other than the State of New
York. The Company hereby irrevocably submits to the exclusive jurisdiction of the state and 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. The Company hereby irrevocably waives personal service of process
and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to the Company at the address set
forth in Section 8(i) above or such other address as the Company subsequently delivers to the Holder and agrees that such service shall
constitute good and sufficient service of process and notice thereof. 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, to realize on any collateral or any other security for such obligations, or to enforce a judgment or other court ruling
in favor of the Holder. If either party shall commence an action, suit or proceeding to enforce any provisions of this Warrant, the prevailing
party in such action, suit or proceeding shall be reimbursed by the other party for their reasonable attorneys’ fees and other
costs and expenses incurred with the investigation, preparation and prosecution of such action or proceeding. THE COMPANY HEREBY IRREVOCABLY
WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION
WITH OR ARISING OUT OF THIS WARRANT OR ANY TRANSACTION CONTEMPLATED HEREBY.

  

11.
DISPUTE RESOLUTION. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the
Warrant Shares, the Company shall cause the Transfer Agent to issue to the Holder the number of shares of Common Stock that is not disputed
and the Company shall submit the disputed determinations or arithmetic calculations via facsimile or electronic mail within two (2) Business
Days of receipt of the Exercise Notice or other event giving rise to such dispute, as the case may be, to the Holder. If the Holder and
the Company are unable to agree upon such determination or calculation of the Exercise Price or the Warrant Shares within three (3) Business
Days of such disputed determination or arithmetic calculation being submitted to the Holder, then the Company shall, within two (2) Business
Days submit via facsimile or electronic mail (a) the disputed determination of the Exercise Price to an independent, reputable investment
bank selected by the Holder and approved by the Company, such approval not to be unreasonably withheld, conditioned or delayed or (b)
the disputed arithmetic calculation of the Warrant Shares to the Company’s independent, outside accountant. The Company shall cause
at its expense the investment bank or the accountant, as the case may be, to perform the determinations or calculations and notify the
Company and the Holder of the results no later than ten (10) Business Days from the time it receives the disputed determinations or calculations.
Such investment bank’s or accountant’s determination or calculation, as the case may be, shall be binding upon all parties
absent demonstrable error.

 

12.
REMEDIES, 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 any 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 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.

 

    	 

    	 

    

 

13.
TRANSFER. This Warrant and the Warrant Shares may be offered for sale, sold, transferred, pledged or assigned without the consent
of the Company.

  

14.
SEVERABILITY; CONSTRUCTION; HEADINGS. 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). 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.

 

15.
DISCLOSURE. Upon receipt or delivery by the Company of any notice in accordance with the terms of this Warrant, unless the Company
has in good faith determined that the matters relating to such notice do not constitute material, nonpublic information relating to the
Company or its subsidiaries, the Company shall contemporaneously with any such receipt or delivery publicly disclose such material, nonpublic
information on a Current Report on Form 8-K or otherwise. In the event that the Company believes that a notice contains material, nonpublic
information relating to the Company or its subsidiaries, the Company so shall indicate to such Holder contemporaneously with delivery
of such notice, and in the absence of any such indication, the Holder shall be allowed to presume that all matters relating to such notice
