	Warrant
    Shares: 22,857,143	Initial
Exercise Date: March 2, 2022


 


THIS
COMMON STOCK PURCHASE WARRANT (the “Warrant”) certifies that, for value received, [____________], or its assigns (the “Holder”)
is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter set forth, at any time on or after
the date hereof (the “Initial Exercise Date”) and on or prior to the close of business on the five (5) year anniversary of
the Initial Exercise Date (the “Termination Date”) but not thereafter, to subscribe for and purchase from Curative Biotechnology,
Inc., a Florida corporation (the “Company”), up to 22,857,143 shares of common stock, of the Company (the “Common Stock”)
(subject to adjustment hereunder, the “Warrant Shares”). The purchase price of one Warrant Share under this Warrant shall
be equal to the Exercise Price, as defined in Section 2(b).

Section
2. Exercise.


 


(a)
Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times on or after the Initial
Exercise Date and on or before the Termination Date by delivery to the Company (or such other office or agency of the Company as it may
designate by notice in writing to the registered Holder at the address of the Holder appearing on the books of the Company) of a duly
executed copy by facsimile or e-mail attachment, of the Notice of Exercise Form annexed hereto. Within two (2) Trading Days following
the date said Notice of Exercise is delivered to the Company, the Holder shall deliver the aggregate Exercise Price for the shares specified
in the applicable Notice of Exercise by wire transfer or cashier’s check drawn on a United States bank unless the cashless exercise
procedure specified in Section 2(c) below is specified in the applicable Notice of Exercise. Notwithstanding anything herein to the contrary
(although the Holder may surrender the Warrant to, and receive a replacement Warrant from, the Company), 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 the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting
in purchases of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding
number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Holder and
the Company shall maintain records showing the number of Warrant Shares purchased and the date of such purchases. The Company shall deliver
any objection to any Notice of Exercise Form within one (1) Trading Day of delivery of such notice. The Holder and any assignee, by acceptance
of this Warrant, acknowledges and agrees that, by reason of the provisions of this paragraph, following the purchase of a portion of
the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount
stated on the face hereof.


 


(b)
Exercise Price. The exercise price per share of the Common Stock under this Warrant shall be $0.0001, subject to adjustment hereunder
(the “Exercise Price”).


 


(c)
Cashless Exercise. If at any time after the earlier of (i) the six month anniversary of the date of the Purchase Agreement and
(ii) the completion of the then-applicable holding period required by Rule 144, or any successor provision then in effect, there is no
effective Registration Statement registering, or no current prospectus available for, the resale of the Warrant Shares by the Holder,
then this Warrant may also be exercised, in whole or in part, at such time by means of a “cashless exercise” in which the
Holder shall be entitled to receive a number of Warrant Shares equal to the quotient obtained by dividing [(A x B) – (A x C)] by
(B), where:


 


	 	(A)	=	 the number of Warrant Shares that would be issuable upon
exercise of this Warrant in accordance with the terms of this Warrant if such exercise were by means of a cash exercise rather than a
cashless exercise;
	 	 	 	 
	 	(B)	=	 the VWAP for the Trading Day immediately prior to the date
on which the Holder makes such “cashless exercise” election; and
	 	 	 	 
	 	(C)	=	the Exercise Price of this
Warrant, as adjusted hereunder, at the time of such exercise.




 




    	Page 2 of 14



    	 



    

 


If
Warrant Shares are issued in such a cashless exercise, the parties acknowledge and agree that in accordance with Section 3(a)(9) of the
Securities Act, the Warrant Shares shall take on the 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 2(c).


 


Notwithstanding
anything herein to the contrary, if on the Termination Date (unless the Holder notifies the Company otherwise) if there is no effective
Registration Statement covering the resale of the Warrant Shares by the Holder, then this Warrant shall be automatically exercised via
cashless exercise pursuant to this Section 2 (c).


 


(d)
Mechanics of Exercise.


 


(i)
Delivery of Certificates Upon Exercise. Warrant Shares purchased hereunder shall be transmitted to the Holder by the Transfer
Agent to the Holder by crediting the account of the Holder’s or its designee’s prime broker with The Depository Trust Company
through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system and either
(A) there is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by
the Holder or (B) this Warrant is being exercised via cashless exercise and Rule 144 is available in either case complying with the transfer
restrictions set forth in the Purchase Agreement, and otherwise by physical delivery to the address specified by the Holder in the Notice
of Exercise by the date that is two (2) Trading Days (five (5) Trading Days for addresses outside of the Continental United States) after
the latest of (A) the delivery to the Company of the Notice of Exercise and (B) payment of the aggregate Exercise Price as set forth
above (unless by cashless exercise, if permitted) (such date, the “Warrant Share Delivery Date”). The Warrant Shares shall
be deemed to have been issued, and Holder or any other person so designated to be named therein shall be deemed to have become a holder
of record of such shares for all purposes, as of the date the Warrant has been exercised, with payment to the Company of the Exercise
Price (or by cashless exercise, if permitted) and all taxes required to be paid by the Holder, if any, pursuant to Section 2(d)(vi) prior
to the issuance of such shares, having been paid. The Company understands that a delay in the delivery of the Warrant Shares after the
Warrant Share Delivery Date could result in economic loss to the Holder. As compensation to the Holder for such loss, the Company agrees
to pay (as liquidated damages and not as a penalty) to the Holder for late issuance of Warrant Shares upon exercise of this Warrant the
proportionate amount of $10 per trading Day (increasing to $20 per Trading Day after the fifth (5th) Trading Day) after the
Warrant Share Delivery Date for each $1,000 of Exercise Price of Warrant Shares for which this Warrant is exercised which are not timely
delivered. In no event shall liquidated damages for any one transaction exceed $1,000.00 for the first ten Trading Days. The Company
shall pay any payments incurred under this Section 2(d)(i) in immediately available funds upon demand. Furthermore, in addition to any
other remedies which may be available to the Holder, in the event that the Company fails for any reason to effect delivery of the Warrant
Shares by the Warrant Share Delivery Date, the Holder may revoke all or part of the relevant Warrant exercise by delivery of a notice
to such effect to the Company, whereupon the Company and the Holder shall each be restored to their respective positions immediately
prior to the exercise of the relevant portion of this Warrant, except that the liquidated damages described above shall be payable through
the date notice of revocation or rescission is given to the Company.

(ii)
Delivery of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of
a Holder and upon surrender of this Warrant certificate, at the time of delivery of the certificate or certificates representing Warrant
Shares, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unpurchased Warrant Shares called for
by this Warrant, which new Warrant shall in all other respects be identical to this Warrant.


 


(iii)
Rescission Rights. If the Company fails to deliver the Warrant Shares cause the Transfer Agent to transmit to the Holder the Warrant
Shares pursuant to Section 2(d)(i) by the Warrant Share Delivery Date, then the Holder will have the right, at any time prior to issuance
of such Warrant Shares, to rescind such exercise.


 


(iv)
Compensation for Buy-In on Failure to Timely Deliver Certificates Upon Exercise. In addition to any other rights available to
the Holder, if the Company fails to deliver the Warrant Shares, or cause the Transfer Agent to transmit to the Holder the Warrant Shares
pursuant to an exercise on or before the Warrant Share Delivery Date, 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 (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 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 certificates representing shares of Common Stock upon
exercise of the Warrant as required pursuant to the terms hereof.


 


(v)
No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise
of this Warrant. As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such exercise, the Company
shall, at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied
by the Exercise Price or round up to the next whole share.


 




    	Page 4 of 14



    	 



    

 


(vi)
Charges, Taxes and Expenses. Issuance of certificates for Warrant Shares shall be made without charge to the Holder for any issue
or transfer tax or other incidental expense in respect of the issuance of such certificate including any charges of any clearing firm,
all of which taxes and expenses shall be paid by the Company, and such certificates shall be issued in the name of the Holder or in such
name or names as may be directed by the Holder; provided, however, that in the event certificates for Warrant Shares are
to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment
Form attached hereto duly executed by the Holder and the Company may require, as a condition thereto, the payment of a sum sufficient
to reimburse it for any transfer tax incidental thereto. The Company shall pay all Transfer Agent fees required for same-day processing
of any Notice of Exercise.


 


(vii)
Closing of Books. The Company will not close its stockholder books or records in any manner which by itself prevents the timely
exercise of this Warrant, pursuant to the terms hereof.


 


(e)
Holder’s Exercise Limitations. The Company shall not effect any exercise of this Warrant, and a Holder shall not have the
right to exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such issuance
after exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s Affiliates, and any other
Persons acting as a group together with the Holder or any of the Holder’s Affiliates), would beneficially own in excess of the
Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially
owned by the Holder and its Affiliates shall include the number of shares of Common Stock issuable upon exercise of this Warrant with
respect to which such determination is being made, but shall exclude the number of shares of Common Stock which would be issuable upon
(i) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the Holder or any of its Affiliates and (ii)
exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company (including, without limitation,
any other Common Stock Equivalents) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially
owned by the Holder or any of its Affiliates. Except as set forth in the preceding sentence, for purposes of this Section 2(e), beneficial
ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder,
it being acknowledged by the Holder that the Company is not representing to the Holder that such calculation is in compliance with Section
13(d) of the Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the
extent that the limitation contained in this Section 2(e) applies, the determination of whether this Warrant is exercisable (in relation
to other securities owned by the Holder together with any Affiliates) and of which portion of this Warrant is exercisable shall be in
the sole discretion of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder’s determination
of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates) and of which
portion of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Company shall have no obligation
to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall
be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes
of this Section 2(e), in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding
shares of Common Stock as reflected in (A) the Company’s most recent periodic or annual report filed with the Commission, as the
case may be, (B) a more recent public announcement by the Company or (C) a more recent written notice by the Company or the Transfer
Agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of a Holder, the Company shall
within one Trading Day confirm orally and in writing 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 or its Affiliates since the date as of which such number of outstanding shares
of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% of the number of shares of the Common
Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon exercise of this Warrant. The
Holder, upon not less than 61 days’ prior notice to the Company, may increase the Beneficial Ownership Limitation provisions of
this Section 2(e) solely with respect to the Holder’s Warrant, provided that the Beneficial Ownership Limitation in no event exceeds
9.99% of the number of shares of Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon
exercise of this Warrant held by the Holder and the provisions of this Section 2(e) shall continue to apply. Any such increase will not
be effective until the 61st day after such notice is delivered to the Company. The Holder may also decrease the Beneficial
Ownership Limitation provisions of this Section 2(e) solely with respect to the Holder’s Warrant at any time, which decrease shall
be effectively immediately upon delivery of notice to the Company. The provisions of this paragraph shall be construed and implemented
in a manner otherwise than in strict conformity with the terms of this Section 2(e) to correct this paragraph (or any portion hereof)
which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or to make changes or supplements
necessary or desirable to properly give effect to such limitation. The limitations contained in this paragraph shall apply to a successor
holder of this Warrant.

Section
3. Certain Adjustments. Except with respect to an Exempt Issuance the following adjustments shall be made to this Warrant:


 


(a)
Stock Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or otherwise
makes a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares
of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon exercise of this
Warrant or pursuant to any of the other Transaction Documents), (ii) subdivides outstanding shares of Common Stock into a larger number
of shares, combines (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or
(iv) issues by reclassification of shares of the Common Stock any shares of capital stock of the Company, then the number of shares issuable
upon exercise of this Warrant shall be proportionately adjusted based on the number of shares of Common Stock (excluding treasury shares,
if any) outstanding immediately before such event and the number of shares of Common Stock outstanding immediately after such event..
Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the record date for the determination of stockholders
entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision,
combination or re-classification.


 


	 	(b)	Adjustments for Issuance of Additional Securities in a Qualified
Offering. In the event that the Company issue or sells additional shares of Common Stock or Common Stock Equivalents in a Qualified
Offering at a price per share which multiplied by 75% is less than the Warrant Calculation Price, the number of Warrant Shares issuable
upon exercise of this Warrant will increase to be equal to the product obtained by multiplying: (WCP/BP) x (WS) whereby:




 


(WCP)
= the Warrant Calculation Price.


 


(BP)
= 75% of the price per share sold in the Qualified Offering.


 


(WS)
= the number of Warrant Shares that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant immediately
prior to the Qualified Offering if such exercise were by means of a cash exercise rather than a cashless exercise;


 


The
term “Warrant Calculation Price” means $0.05


 


(c)
Subsequent Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time the Company grants,
issues or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the record
holders of any class of shares 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 on exercise
hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date on which a record is taken for
the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares
of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, to the extent that the
Holder’s right to participate in any such Purchase Right would result in the Holder exceeding the Beneficial Ownership Limitation,
then the Holder shall not be entitled to participate in such Purchase Right to such extent (or beneficial ownership of such shares of
Common Stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for
the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).
Notwithstanding the foregoing, no Purchase Rights will be made under this Section 3(c) in respect of an Exempt Issuance.


 


(d)
Pro Rata Distributions. If the Company, at any time while this Warrant is outstanding, shall distribute to all holders of Common
Stock (and not to the Holder) evidences of its indebtedness or assets (including cash and cash dividends) or rights or warrants to subscribe
for or purchase any security other than the Common Stock (which shall be subject to Section 3(a)), then in each such case the Holder
will be entitled to acquire such evidences of its indebtedness or assets (including cash and cash dividends) or rights or warrants to
subscribe for or purchase any security other than the Common Stock so distributed 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 on exercise
hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date on which a record is taken for
the grant, issuance or sale of such evidences of its indebtedness or assets (including cash and cash dividends) or rights or warrants
to subscribe for or purchase any security other than the Common Stock. In either case the adjustments shall be described in a statement
provided to the Holder of the portion of assets or evidences of indebtedness so distributed or such subscription rights applicable to
one share of Common Stock. Such adjustment shall be made whenever any such distribution is made and shall become effective immediately
after the record date mentioned above.

(e)
Fundamental Transaction. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in one or
more related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company, directly
or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of
its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer
(whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell, tender or exchange
their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the outstanding Common Stock,
(iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification, reorganization or recapitalization
of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for
other securities, cash or property, or (v) the Company, directly or indirectly, in one or more related transactions consummates a stock
or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off
or scheme of arrangement) with another Person or group of Persons whereby such other Person or group acquires more than 50% of the outstanding
shares of Common Stock (not including any shares of Common Stock held by the other Person or other Persons making or party to, or associated
or affiliated with the other Persons making or party to, such stock or share purchase agreement or other business combination) (each
a “Fundamental Transaction”), then, upon any subsequent exercise of this Warrant, the Holder shall have the right to receive,
for each Warrant Share that would have been issuable upon such exercise immediately prior to the occurrence of such Fundamental Transaction
(without regard to any limitation on the exercise of this Warrant), at the option of the Holder the number of shares of Common Stock
of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and any additional consideration (the
“Alternate Consideration”) receivable as a result of such Fundamental Transaction by a holder of the number of shares of
Common Stock for which this Warrant is exercisable immediately prior to such Fundamental Transaction (without regard to any limitation
on the exercise of this Warrant). For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted
to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock
in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in a reasonable
manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given
any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same
choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction. Notwithstanding
anything to the contrary, other than a Fundamental Transaction in which the Company is the surviving entity and the Company’s Common
Stock continues to be quoted or listed on a Trading Market, the Company or any Successor Entity (as defined below) shall, at the Holder’s
option, exercisable at any time concurrently with, or within 30 days after, the consummation of the Fundamental Transaction, purchase
this Warrant from the Holder by paying to the Holder an amount of cash equal to the greater of (i) the Black Scholes Value of the remaining
unexercised portion of this Warrant on the date of the consummation of such Fundamental Transaction and (ii) the positive difference
between the cash per share paid in such Fundamental Transaction minus the then in effect Exercise Price; provided, however, that if the
Fundamental Transaction is not within the Company’s control, including not approved by the Company’s Board of Directors,
Holder shall only be entitled to receive from the Company or any Successor Entity, as of the date the Fundamental Transaction is consummated,
the same type and form of consideration (and in the same proportion), as the greater of (i) 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 the Fundamental Transaction
and (ii) the positive difference between the cash per share paid in such Fundamental Transaction minus the then in effect Exercise Price,
whether that consideration be in the form of cash, stock or any combination thereof, or whether the holders of Common Stock are given
a choice to receive from among alternative forms of consideration in connection with the Fundamental Transaction. “Black Scholes
Value” means the value of the unexercised portion of this Warrant based on the Black and Scholes Option Pricing Model obtained
from the “OV” function on Bloomberg L.P. determined as of the day of consummation of the applicable Fundamental Transaction
for pricing purposes and reflecting (A) a risk-free interest rate corresponding to the U.S. Treasury rate for a period equal to the time
between the date of the public announcement of the applicable Fundamental Transaction and the Termination Date,(B) an expected volatility
equal to the greater of 100% and the 100 day volatility obtained from the HVT function on Bloomberg L.P. as of the Trading Day immediately
following the public announcement of the applicable Fundamental Transaction, (C) the underlying price per share used in such calculation
shall be the sum of the price per share being offered in cash, if any, plus the value of any non-cash consideration, if any, being offered
in such Fundamental Transaction and (D) a remaining option time equal to the time between the date of the public announcement of the
applicable Fundamental Transaction and the Termination Date. The Company shall cause any successor entity in a Fundamental Transaction
in which the Company is not the survivor (the “Successor Entity”) to assume in writing all of the obligations of the Company
under this Warrant and the other Transaction Documents in accordance with the provisions of this Section 3(e) pursuant to written agreements
in form and substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such Fundamental
Transaction and shall, at the option of the Holder, 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 which is exercisable for a corresponding
number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable
and receivable upon exercise of this Warrant prior to such Fundamental Transaction (without regard to any limitation on the exercise
of this Warrant), 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 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), and which is reasonably satisfactory in form and substance
to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for
(so that from and after the date of such Fundamental Transaction, the provisions of this Warrant and the other Transaction Documents
referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company
and shall assume all of the obligations of the Company under this Warrant and the other Transaction Documents with the same effect as
if such Successor Entity had been named as the Company herein. Notwithstanding the foregoing, no adjustment shall be made pursuant to
this Section 3(f) with respect to an Exempt Issuance (as defined in the Purchase Agreement)

(f)
Calculations. All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the
case may be. For purposes of this Section 3, the number of shares of Common Stock deemed to be issued and outstanding as of a given date
shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.


 


(g)
Notice to Holder.


 


(i)
Adjustment to Exercise Price. Whenever the Exercise Price or the number of Warrant Shares to be received hereunder is adjusted
pursuant to any provision of this Section 3, the Company shall promptly email to the Holder a notice setting forth the Exercise Price
after such adjustment and any resulting adjustment to the number of Warrant Shares and setting forth a brief statement of the facts requiring
such adjustment. The Holder may supply an email address to the Company and change such address.


 


(ii)
Notice to Allow Exercise by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on
the Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the
Company shall authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or purchase any shares of
capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection with
any reclassification of the Common Stock, any consolidation or merger to which the Company is a party, any sale or transfer of all or
substantially all of the assets of the Company, or any compulsory share exchange whereby the Common Stock is converted into other securities,
or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company,
then, in each case, the Company shall deliver to the Holder at its last address as it shall appear upon the Warrant Register of the Company,
at least 20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which
a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken,
the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions, redemption, rights or
warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange
is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be
entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer or share exchange; provided that the failure to email such notice or any defect therein or in the
emailing thereof shall not affect the validity of the corporate action required to be specified in such notice. To the extent that any
notice provided hereunder constitutes, or contains, material, non-public information regarding the Company or any of the Subsidiaries
(as determined in good faith by the Company), the Company shall simultaneously file such notice with the Commission pursuant to a Current
Report on Form 8-K. The Holder shall remain entitled to exercise this Warrant during the period commencing on the date of such notice
to the effective date of the event triggering such notice except as may otherwise be expressly set forth herein.


 


Section
4. Transfer of Warrant.


 


(a)
Transferability. Subject to compliance with any applicable securities laws and the provisions of the Purchase Agreement, this
Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part, upon
surrender of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this
Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any
transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company shall execute
and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the denomination or denominations
specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not
so assigned, and this Warrant shall promptly be cancelled. The Warrant, if properly assigned in accordance herewith, may be exercised
by a new holder for the purchase of Warrant Shares without having a new Warrant issued.


 


(b)
New Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of
the Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by
the Holder or its agent or attorney. Subject to compliance with Section 4(a), as to any transfer which may be involved in such division
or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided
or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall be dated the initial issuance date of
this Warrant and shall be identical with this Warrant except as to the number of Warrant Shares issuable pursuant thereto.

(c)
Warrant Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the
“Warrant Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered
Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for
all other purposes, absent actual notice to the contrary.


 


Section
5. Miscellaneous.


 


(a)
No Rights as Stockholder Until Exercise. This Warrant does not entitle the Holder to any voting rights, dividends or other rights
as a stockholder of the Company prior to the exercise hereof other than as explicitly set forth in Section 3.


 


(b)
Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares,
and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it, and upon surrender and cancellation
of such Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor
and dated as of such cancellation, in lieu of such Warrant or stock certificate.


 


(c)
Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required
or granted herein shall not be a Trading Day, then, such action may be taken or such right may be exercised on the next succeeding Trading
Day.


 


(d)
Authorized Shares. The Company covenants that, during the period the Warrant is outstanding, it will reserve from its authorized
and unissued Common Stock, free of preemptive rights the number of shares of Common Stock issuable upon exercise of this Warrant, subject
to adjustment for stock dividends, stock splits, combination and similar events. The Company further covenants that its issuance of this
Warrant shall constitute full authority to its officers who are charged with the duty of executing stock certificates to execute and
issue the necessary certificates for the Warrant Shares upon the exercise of the purchase rights under this Warrant. The Company will
take all such reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation
of any applicable law or regulation, or of any requirements of any Trading Market upon which the Common Stock may be listed. The Company
covenants that all Warrant Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon
exercise of the purchase rights represented by this Warrant and payment for such Warrant Shares in accordance herewith, be duly authorized,
validly issued, fully paid and non-assessable and free from all taxes, liens and charges created by the Company in respect of the issue
thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

Except
and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending
its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale
of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant,
but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary
or appropriate to protect the rights of Holder as set forth in this Warrant against impairment. Without limiting the generality of the
foregoing, the Company will (i) not increase the par value of any Warrant Shares above the amount payable therefor upon such exercise
immediately prior to such increase in par value, (ii) take all such action as may be necessary or appropriate in order that the Company
may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant and (iii) use best efforts
to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof, as may be, necessary
to enable the Company to perform its obligations under this Warrant.


 


Before
taking any action which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the
Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from
any public regulatory body or bodies having jurisdiction thereof.


 


(e)
Jurisdiction. All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be determined
in accordance with the provisions of the Purchase Agreement.


 


(f)
Restrictions. The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered or
if not exercised on a cashless basis when Rule 144 is available, may have restrictions upon resale imposed by state and federal securities
laws.


 


(g)
Non-waiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall
operate as a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies. Without limiting any other provision
of this Warrant or the Purchase Agreement, if the Company willfully and knowingly fails to comply with any provision of this Warrant,
which results in any material damages to the Holder, the Company shall pay to the Holder such amounts as shall be sufficient to cover
any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate proceedings, incurred
by the Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.


 


(h)
Notices. Any notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall
be delivered in accordance with the notice provisions of the Purchase Agreement.


 




    	Page 10 of 14



    	 



    

 


(i)
Limitation of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant
to purchase Warrant Shares, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of
the Holder for the purchase price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company
or by creditors of the Company.


 


(j)
Remedies. The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will
be entitled to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate
compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to
assert the defense in any action for specific performance that a remedy at law would be adequate or that there is no irreparable harm
and not to require the posting of a bond or other security.


 


(k)
Successors and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall
inure to the benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns
of Holder. The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and shall
be enforceable by the Holder or holder of Warrant Shares.


 


(l)
Amendment. This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and
Holder the Warrants issued pursuant to the Purchase Agreement.


 


(m)
Severability. Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid
under applicable law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall
be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining
provisions of this Warrant.


 


(n)
Headings. The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed
a part of this Warrant.
