This
Warrant supersedes, amends and restates, in its entirety, the Common Stock Purchase Warrant that was originally issued to the Holder

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 Exercisability Date and on or before the Termination Date by delivery to the Company of a duly executed PDF copy
submitted by e-mail (or e-mail attachment) of the Notice of Exercise in the form annexed hereto (the “Notice of Exercise”).
Within the earlier of (i) two (2) Trading Days and (ii) the number of Trading Days comprising the Standard Settlement Period (as defined
in Section 2(d)(i) herein) following the date of exercise as aforesaid, 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. No ink-original Notice
of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise
be required. 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 three (3) Trading Days of the date on which
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

showing the number of Warrant Shares purchased and the date of such purchases. The Company shall deliver any objection to any Notice
of Exercise within one (1) Business Day of receipt of such notice. 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.

“Exercise Price”).


 


c)
Cashless Exercise. If at the time of exercise hereof there is no effective registration statement registering, or the prospectus contained
therein is not available for the issuance of the Warrant Shares to 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-B) (X)] by (A), where:


 


(A)
= as applicable: (i) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise if such Notice of
Exercise is (1) both executed and delivered pursuant to Section 2(a) hereof on a day that is not a Trading Day or (2) both executed and
delivered pursuant to Section 2(a) hereof on a Trading Day before the opening of “regular trading hours” (as defined in Rule
600(b)(68) of Regulation NMS promulgated under the federal securities laws) on such Trading Day, (ii) at the option of the Holder, either
(y) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise or (z) the Bid Price of the Common
Stock on the principal Trading Market as reported by Bloomberg L.P. as of the time of the Holder’s execution of the applicable
Notice of Exercise if such Notice of Exercise 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 2(a) hereof or (iii) the VWAP on the date of the applicable Notice of Exercise if the date of such Notice of Exercise
is a Trading Day and such Notice of Exercise is both executed and delivered pursuant to Section 2(a) hereof after the close of “regular
trading hours” on such Trading Day;


 


(B)
= the Exercise Price of this Warrant, as adjusted hereunder; and


 


(X)
= 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.


 


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 registered characteristics of the Warrants being exercised. The Company agrees not
to take any position contrary to this Section 2(c).


 


“Bid
Price” means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is
then listed or quoted on a Trading Market, the bid price of the Common Stock for the time in question (or the nearest preceding date)
on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (based on a Trading Day from 9:30
a.m. (New York City time) to 4:02 p.m. (New York City time)), (b) if OTCQB or OTCQX is not a Trading Market, the volume weighted average
price of the Common Stock for such date (or the nearest preceding date) on OTCQB or OTCQX as applicable, (c) if the Common Stock is not
then listed or quoted for trading on OTCQB or OTCQX and if prices for the Common Stock are then reported on The Pink Open Market (or
a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of the Common
Stock so reported, or (d) in all other cases, the fair market value of a share of Common Stock as determined by an independent appraiser
selected in good faith by the Purchasers of a majority in interest of the Securities then outstanding and reasonably acceptable to the
Company, the fees and expenses of which shall be paid by the Company.


 


“VWAP”
means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed
or quoted on a Trading Market, the daily volume weighted average price of the Common Stock for such date (or the nearest preceding date)
on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (based on a Trading Day from 9:30
a.m. (New York City time) to 4:02 p.m. (New York City time)), (b) if OTCQB or OTCQX is not a Trading Market, the volume weighted average
price of the Common Stock for such date (or the nearest preceding date) on OTCQB or OTCQX as applicable, (c) if the Common Stock is not
then listed or quoted for trading on OTCQB or OTCQX and if prices for the Common Stock are then reported on The Pink Open Market (or
a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of the Common
Stock so reported, or (d) in all other cases, the fair market value of a share of Common Stock as determined by an independent appraiser
selected in good faith by the Purchasers of a majority in interest of the Securities then outstanding and reasonably acceptable to the
Company, the fees and expenses of which shall be paid by the Company.


 


Notwithstanding
anything herein to the contrary, on the Termination Date, this Warrant shall be automatically exercised via cashless exercise pursuant
to this Section 2(c).


 






    	 



     


    




 






d)
Mechanics of Exercise.


 


i.
Delivery of Warrant Shares Upon Exercise. The Company shall cause the Warrant Shares purchased hereunder to be transmitted by the Transfer
Agent to the Holder by crediting the account of the Holder’s or its designee’s balance account 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 Holder or (B) this Warrant is (at a time when the Holder has a sufficient Rule 144 holding period for the Warrant/Warrant Shares)
being exercised via cashless exercise, and otherwise by physical delivery of a certificate, registered in the Company’s share register
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
to the address specified by the Holder in the Notice of Exercise by the date that is the earliest of (i) two (2) Trading Days after the
delivery to the Company of the Notice of Exercise, (ii) one (1) Trading Day after delivery of the aggregate Exercise Price to the Company
and (iii) the number of Trading Days comprising the Standard Settlement Period after the delivery to the Company of the Notice of Exercise
(such date, the “Warrant Share Delivery Date”). Upon delivery of the Notice of Exercise, the Holder shall be deemed for all
corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective
of the date of delivery of the Warrant Shares, provided that payment of the aggregate Exercise Price (other than in the case of a cashless
exercise) is received within the earlier of (i) two (2) Trading Days and (ii) the number of Trading Days comprising the Standard Settlement
Period following delivery of the Notice of Exercise. If the Company fails for any reason to deliver to the Holder the Warrant Shares
subject to a Notice of Exercise by the Warrant 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 VWAP of the Common Stock on the date of
the applicable Notice of Exercise), $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 such Warrant Share Delivery Date until such Warrant Shares are delivered or Holder
rescinds such exercise. The Company agrees to maintain a transfer agent that is a participant in the FAST program so long as this Warrant
remains outstanding and exercisable. As used herein, “Standard Settlement Period” means the standard settlement period, expressed
in a number of Trading Days, on the Company’s primary Trading Market with respect to the Common Stock as in effect on the date
of delivery of the Notice of Exercise.


 


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 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 with this Warrant.


 


iii.Rescission
Rights. If the Company fails to 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 to rescind such exercise.


 


iv.
Compensation for Buy-In on Failure to Timely Deliver Warrant Shares Upon Exercise. In addition to any other rights available to the Holder,
if the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares in accordance with the provisions of Section
2(d)(i) above 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 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.


 


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.


 


vi.
Charges, Taxes and Expenses. Issuance of 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 Warrant Shares, all of which taxes and expenses shall be paid by the Company, and
such Warrant Shares 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 that 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 and all fees to the Depository Trust Company (or another established
clearing corporation performing similar functions) required for same-day electronic delivery of the Warrant Shares.


 




    	 



     


    




 


vii.
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.


 


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 (such Persons, “Attribution Parties”)),
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 and Attribution Parties 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 or Attribution Parties 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 or Attribution Parties. 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 Securities 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 Securities 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 Attribution Parties) 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 Attribution Parties) 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 Securities 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 or Attribution Parties
since the date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation”
shall be 9.99% 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 notice to the Company, may increase or decrease the Beneficial Ownership
Limitation provisions of this Section 2(e), 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(e) shall continue to apply. Any increase in the Beneficial Ownership
Limitation 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(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.


 


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), (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)
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, that, 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).


 


d)
Pro Rata Distributions. During such time as this Warrant is outstanding, if 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 or options 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 on exercise hereof, including without limitation, the Beneficial Ownership Limitation)
immediately before the date of 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 exceeding the Beneficial Ownership
Limitation, then the Holder shall not be entitled to participate in such Distribution to such extent (or in the beneficial ownership
of any shares of Common Stock as a result of such Distribution to such extent) and the portion of such Distribution shall be held in
abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial
Ownership Limitation). To the extent that this Warrant has not been partially or completely exercised at the time of such Distribution,
such portion of the Distribution shall be held in abeyance for the benefit of the Holder until the Holder has exercised this Warrant.


 






    	 



     


    




 


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 (and all of its Subsidiaries,
taken as a whole), 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, merger 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 before
the occurrence of such Fundamental Transaction, at the option of the Holder (without regard to any limitation in Section 2(e) on the
exercise of this Warrant), 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 before
such Fundamental Transaction (without regard to any limitation in Section 2(e) 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, in the event of a
Fundamental Transaction, 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 (or, if later, the date of the public
announcement of the applicable Fundamental Transaction), purchase this Warrant from the Holder by paying to the Holder an amount of cash
equal to the Black Scholes Value (as defined below) of the remaining unexercised portion of this Warrant on the date of the consummation
of such Fundamental Transaction; 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 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 of the Company in connection with the Fundamental Transaction, 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 the Fundamental Transaction; provided, further, that if holders
of Common Stock of the Company are not offered or paid any consideration in such Fundamental Transaction, such holders of Common Stock
will be deemed to have received common stock of the Successor Entity (which Entity may be the Company following such Fundamental Transaction)
in such Fundamental Transaction. “Black Scholes Value” means the value of this Warrant based on the Black-Scholes Option
Pricing Model obtained from the “OV” function on Bloomberg, L.P. (“Bloomberg”) 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 (determined utilizing a 365 day annualization factor) 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 greater of (i) 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 (ii) the greater of (x) the last VWAP immediately before the public announcement of such Fundamental Transaction
and (y) the last VWAP immediately before the consummation of 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 payment of the
Black Scholes Value will be made by wire transfer of immediately available funds within the later of (i) five Business Days of the Holder’s
election and (ii) the date of consummation of the Fundamental Transaction. 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)
before 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 (without regard to any limitations on the exercise of this Warrant) before
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 number of shares of capital stock and such exercise price being for the purpose of protecting the economic value
of this Warrant immediately before 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.


 




    	 



     


    




 


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 is adjusted pursuant to any provision of this Section 3, the Company shall
promptly deliver to the Holder by email 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.


 


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 (and all of its Subsidiaries, taken as a whole) 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, 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 delivered by email to the Holder at its
last email address as it shall appear upon the Warrant Register of the Company, at least 20 calendar days before 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 deliver such notice or any defect therein or in the delivery thereof shall not affect the validity of the
corporate action required to be specified in such notice. To the extent that any notice provided in this Warrant constitutes, or contains,
material, non-public information regarding the Company or any of the Subsidiaries, 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.


 


h)
Voluntary Adjustment By Company. Subject to the rules and regulations of the Trading Market, the Company may at any time during the term
of this Warrant, subject to the prior written consent of the Holder, 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.


 


Section
4. Transfer of Warrant.


 


a)
Transferability. This Warrant and all rights hereunder 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. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant
to the Company unless the Holder has assigned this Warrant in full, in which case, the Holder shall surrender this Warrant to the Company
within three (3) Trading Days of the date on which the Holder delivers an assignment form to the Company assigning this Warrant in full.
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; No Settlement in Cash. This Warrant does not entitle the Holder to any voting rights, dividends
or other rights as a stockholder of the Company before the exercise hereof as set forth in Section 2(d)(i), except as expressly set forth
in Section 3. Without limiting any rights of a Holder to receive Warrant Shares on a “cashless exercise” pursuant to Section
2(c) or to receive cash payments pursuant to Section 2(d)(i) and Section 2(d)(iv) herein, in no event shall the Company be required to
net cash settle an exercise of this Warrant.


 






    	 



     


    




 


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 issuing the necessary 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 and payment for such Warrant Shares in accordance herewith, 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 before 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.


 


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 the Transaction Documents shall
be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles
of conflicts of law thereof.


 


f)
Restrictions. The Holder, by acceptance of this Warrant, acknowledges that the Warrant Shares acquired upon the exercise of this Warrant
may have restrictions upon resale imposed by state and federal securities laws. The Holder, by acceptance of this Warrant, covenants
to comply with any such 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 the Holder’s rights, powers or remedies. Without limiting any other provision
of this Warrant, 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 in
writing and shall be deemed given and effective on the earliest of: (a) the time of transmission, if such notice or communication is
delivered via email attachment at the Holder’s e-mail address on file with the Company at or before 5:30 p.m. (New York City time)
on a Trading Day, (b) the next Trading Day after the time of transmission, if such notice or communication is delivered via email attachment
at the Holder’s e-mail address on file with the Company 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 (2nd) Trading Day following the date of mailing to the Holder’s mail address on file with
the Company, if sent by U.S. nationally recognized overnight courier service or (d) upon actual receipt by the Holder.


 


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.


 


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 the Holder.


 


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.


 


o)
Registration of Warrant Shares. The Company acknowledges that, pursuant to the Consulting Agreement dated November 9, 2021 between the
Company and GreenBlock Capital LLC, the Company is required to, upon the closing of the Company’s acquisition of NanoSynex Ltd.
(in the event such closing occurs), seek and obtain the registration of the Warrant Shares under the Securities Act on a Form S-3 or
other similar registration statement; and the Company hereby confirms and agrees that it will do so in such event.
