COMMON STOCK PURCHASE WARRANT

 

CURATIVE BIOTECHNOLOGY,
Inc.

 

	Warrant Shares: [*]	Initial Exercise Date: May [*], 2021

 

THIS COMMON STOCK PURCHASE WARRANT
(the “Warrant”) certifies that, for value received, [*] (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 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 3,500,000 shares (the “Warrant Shares”) of common
stock of the Company (“Common Stock”). The purchase price of one share of Common Stock under this Warrant shall be
equal to the Exercise Price, as defined in Section 2(b).

 

Section 1. Reserved.

 

Section 2. Exercise.

 

a) Exercise of Warrant.
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 facsimile copy of the Notice of Exercise Form annexed hereto; and, within 3 “Business Days” (weekdays on which banks
are open for general banking business in New York City, New York) of the date said Notice of Exercise is delivered to the Company, the
Company shall have received payment of the aggregate Exercise Price of the shares thereby purchased by wire transfer or cashier’s
check drawn on a United States bank. Notwithstanding anything herein to the contrary, 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 3 Business 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 1 Business Day of receipt of such notice. In the event of any dispute or discrepancy, the records of the Company shall be controlling
and determinative in the absence of manifest error. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree
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.

 

    	1 

     

    

 

b) Exercise Price.
The exercise price per share of the Common Stock under this Warrant shall be $0.11, subject to adjustment hereunder (the “Exercise
Price”).

 

c) Reserved.

 

d) 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 (defined as any person or entity that, directly or indirectly
through one or more intermediaries, controls or is controlled by or is under common control with a Person, as such terms are used in and
construed under Rule 405 under the Securities Act), and any other person or entity 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 (A) exercise of the remaining, nonexercised portion of this
Warrant beneficially owned by the Holder or any of its Affiliates and (B) 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(d), beneficial ownership shall be calculated in accordance with
Section 13(d) of the Securities Exchange Act of 1934, as amended (“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(d) 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(d), 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 Securities Exchange Commission most recent filings or current public information
from the OTC Markets website (C) a more recent public announcement by the Company or (D) any other notice by the Company or the transfer
agent of the Company setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of a Holder, the
Company shall within five Business Days 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 or decrease the Beneficial Ownership
Limitation provisions of this Section 2(d), provided that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number
of shares of the 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(d) shall continue to apply. Any such increase or decrease will not be
effective until the 61st day after such notice is delivered 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(d) 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.

e) Mechanics of Exercise.

 

i. Delivery of Certificates
Upon Exercise. Certificates for shares purchased hereunder shall be transmitted by the transfer agent of the Company to the Holder
by crediting the account of the Holder’s prime broker with the Depository Trust Company through its Deposit Withdrawal Agent Commission
(“DWAC”) system if the Company is then a participant in such system and either (A) there is an effective registration
statement permitting the resale of the Warrant Shares by the Holder or (B) the shares are eligible for resale without volume or manner-of-sale
limitations pursuant to Rule 144 (defined as Rule 144 promulgated by the Securities and Exchange Commission pursuant to the Securities
Act, as such Rule may be amended or interpreted from time to time, or any similar rule or regulation hereafter adopted by the Securities
Exchange Commission having substantially the same purpose and effect as such Rule), and otherwise by physical delivery to the address
specified by the Holder in the Notice of Exercise within 5 Business Days from the delivery to the Company of the Notice of Exercise Form,
surrender of this Warrant (if required) and payment of the aggregate Exercise Price as set forth above (the “Warrant Share Delivery
Date”). This Warrant shall be deemed to have been exercised on the date the Exercise Price is received by the Company. 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 by payment to the Company of the Exercise
Price and all taxes required to be paid by the Holder, if any, pursuant to Section 2(e)(v) prior to the issuance of such shares, have
been paid.

 

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 Holder a new Warrant evidencing the rights of Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new
Warrant shall in all other respects be identical with this Warrant.

 

iii. Rescission Rights.
If the Company fails to cause the transfer agent of the Company to transmit to the Holder a certificate or the certificates representing
the Warrant Shares pursuant to Section 2(e)(i) by the Warrant Share Delivery Date, then, the Holder will have the right to rescind such
exercise.

 

iv. 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 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.

 

    	3 

     

    

 

v. 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, 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.

 

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

 

Section 3. Adjustments
for 

 

a) Stock Dividends
and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or otherwise make 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), (ii) subdivides
outstanding shares of Common Stock into a larger number of shares, (iii) 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 in each case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the
number of shares of Common Stock (excluding treasury shares, if any) outstanding immediately before such event and of which the denominator
shall be the number of shares of Common Stock outstanding immediately after such event and the number of shares issuable upon exercise
of this Warrant shall be proportionately adjusted such that the aggregate Exercise Price of this Warrant shall remain unchanged. 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) Reserved.

 

c) 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.

 

    	4 

     

    

 

d) Notice to Holder.

 

i. Adjustment to
Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall notify the
Holder of the Exercise Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment. In the
event the Company makes a public disclosure with regard to the adjustment, such public disclosure shall be deemed notice to the Holder.

 

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, of any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property, 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 cause to be mailed 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 mail such notice or any defect therein or in the
mailing thereof shall not affect the validity of the corporate action required to be specified in such notice. The Holder is 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.

 

    	5 

     

    

 

Section 4. Transfer
of Warrant.

 

a) Transferability.
Subject to compliance with any applicable securities laws and the conditions set forth in Section 4(d) hereof, 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, 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 original Issue Date 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.

 

d) Transfer Restrictions.
If, at the time of the surrender of this Warrant in connection with any transfer of this Warrant, the transfer of this Warrant shall not
be either (i) registered pursuant to an effective registration statement under the Securities Act and under applicable state securities
or blue sky laws or (ii) eligible for resale without volume or manner-of-sale restrictions pursuant to Rule 144, the Company may require,
as a condition of allowing such transfer, that the Holder or transferee of this Warrant, as the case may be, may be required by the Company
to provide an opinion of counsel with regard to such assignment or transfer.

 

Section 5. Miscellaneous.

 

a) No Rights as Stockholder
Until Exercise. This Warrant does not entitle the Holder to any voting rights or other rights as a stockholder of the Company prior
to the exercise hereof as set forth in Section 2(e)(i).

 

    	6 

     

    

 

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 (which, in the case of the Warrant, shall not include the posting
of any bond), 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 Business Day, then, such action may be taken or such right may be exercised on the next succeeding Business 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 a sufficient number of shares
to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant. 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 the 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, be duly authorized, validly issued, fully paid and nonassessable
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 commercially reasonable 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.

 

    	7 

     

    

 

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 governed by and construed
and enforced in accordance with the internal laws of the State of Florida, without regard to the principles of conflict of laws thereof.
All legal proceedings concerning the interpretation, enforcement and defense of this Warrant (whether brought against a party hereto or
its respective affiliates, directors, officers, shareholders, employees or agents) shall be commenced in the state and federal courts
sitting in the County of Palm Beach, Florida (the “Palm Beach Courts”). Each party hereto hereby irrevocably
submits to the exclusive jurisdiction of the Palm Beach Courts 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 such Palm Beach Courts, or such Palm Beach Courts are
improper or inconvenient venue for such proceeding. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE
LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS WARRANT OR THE TRANSACTIONS CONTEMPLATED
HEREBY.

 

f) Restrictions.
The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered, will have restrictions
upon resale imposed by state and federal securities laws.

 

g) Nonwaiver 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 Holder’s rights, powers or remedies, notwithstanding the fact that all rights hereunder terminate
on the Termination Date. 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 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 Holder in collecting any amounts
due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.

 

    	8 

     

    

 

h) Notices. Any
notice required or permitted hereunder shall be given in writing and shall be conclusively deemed effectively given upon personal delivery
or delivery by courier, or on the first Business Day after transmission if sent by confirmed facsimile transmission or electronic mail

i) Limitation of
Liability. No provision hereof, in the absence of any affirmative action by Holder to exercise this Warrant to purchase Warrant Shares,
and no enumeration herein of the rights or privileges of Holder, shall give rise to any liability of 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.

 

k) Successors and
Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the benefit

l) Amendment.
This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Holder of the Warrant.

 

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.

Common Stock. The purchase price of one share of Common Stock under this Warrant shall be equal to the Exercise Price, as defined
in Section 2(b).

Section
1. Exercise.

 

a)
Exercise of Warrant. 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 3 years following 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 facsimile copy of the Notice of Exercise Form annexed hereto; and, within 3
Business Days of the date said Notice of Exercise is delivered to the Company, the Company shall have received payment of the aggregate
Exercise Price of the shares thereby purchased by wire transfer or cashier’s check drawn on a United States bank. Notwithstanding
anything herein to the contrary, 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 3 Business 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 Holder and any assignee, by acceptance of this Warrant, acknowledge and agree 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 $0.05 (five cents), subject
to adjustment hereunder (the “Exercise Price”).

 

i.
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 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.

 

Section
3. Certain Adjustments.

 

a)
Stock Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or otherwise
make 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), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) 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 then the pricing of the warrants shall be adjusted accordingly..

 

    	2

     

    

 

b)
Fundamental Transaction. If, at any time while this Warrant is outstanding, (i) the Company effects any merger or consolidation
of the Company with or into another Person, (ii) the Company effects any sale of all or substantially all of its assets in one or a series
of related transactions, (iii) any tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to
which holders of Common Stock are permitted to tender or exchange their shares for other securities, cash or property or (iv) the Company
effects any reclassification 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 (each “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, 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 merger, consolidation or disposition of assets by a holder of the number of
shares of Common Stock for which this Warrant is exercisable immediately prior to such event.

 

c)
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.

 

Section
4. Transfer of Warrant.

 

a)
Transferability. Subject to compliance with any applicable securities laws and the conditions set forth in Section 4(d) hereof,
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, may be exercised by a new holder for the
purchase of Warrant Shares without having a new Warrant issued.

 

b)
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.

 

c)
Transfer Restrictions. If, at the time of the surrender of this Warrant in connection with any transfer of this Warrant, the transfer
of this Warrant shall not be eligible for resale without volume or manner-of-sale restrictions pursuant to Rule 144, the Company may
require, as a condition of allowing such transfer, that the Holder or transferee of this Warrant, as the case may be, may be required
by the Company to provide an opinion of counsel with regard to such assignment or transfer.

 

    	3

     

    

 

a)
Authorized Shares.

 

The
Company covenants that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a
sufficient number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant.
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 the Trading
Market upon which the Common Stock may be listed.

 

b)
Governing Law and Venue. All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall
be governed by and construed and enforced in accordance with the internal laws of the State of Florida, without regard to the principles
of conflicts of law thereof.

 

c)
Restrictions. The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered, will
have restrictions upon resale imposed by state and federal securities laws.

 

d)
Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in
writing and shall be deemed given and effective on the earliest of (a) the date of transmission, if such notice or communication is delivered
via facsimile at the facsimile number set forth on the signature pages attached hereto prior to 5:30 p.m. (New York City time) on a Trading
Day, (b) the next Trading Day after the date of transmission, if such notice or communication is delivered via facsimile at the facsimile
number set forth on the signature pages attached hereto on a day that is not a Trading Day or later than 5:30 p.m. (New York City time)
on any Trading Day, (c) the second Trading Day following the date of mailing, if sent by U.S. nationally recognized overnight courier
service, or (d) upon actual receipt by the party to whom such notice is required to be given. The address for such notices and communications
shall be: (i) if to Holder, at its address of records as contained in the Warrant Register, and (ii) if to Company, at its corporate
headquarters.

 

e)
Limitation of Liability. No provision hereof, in the absence of any affirmative action by Holder to exercise this Warrant to purchase
Warrant Shares, and no enumeration herein of the rights or privileges of Holder, shall give rise to any liability of 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.

 

    	4

     

    

 

f)
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.

 

g)
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 of the Company and the successors and permitted assigns of Holder. The provisions
of this Warrant are intended to be for the benefit of all Holders from time to time of this Warrant and shall be enforceable by the Holder
or holder of Warrant Shares.

 

h)
Amendment. This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and
Holder.

 

i)
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.

 

j)
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.
