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 of a duly executed facsimile copy
or 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
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
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.


 


b) Exercise
Price. The exercise price per share of Common Stock under this Warrant shall be $4.80, subject to adjustment hereunder (the “Exercise
Price”).


 



     3


     


    

 


c) Cashless
Exercise. If at 60 days after the date hereof or any time thereafter at the time of exercise hereof there is no effective registration
statement registering, or the prospectus contained therein is not available for the resale of the Warrant Shares by the Holder, then this
Warrant may also be exercised, in whole or in part, at such time by means of a “cashless exercise” in which the Holder shall
be entitled to receive a number of Warrant Shares equal to the quotient obtained by dividing [(A-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 prior to 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 characteristics of the Warrants being exercised, and the holding period of the Warrant Shares being
issued may be tacked on to the holding period of this Warrant. The Company agrees not to take any position contrary to this Section 2(c).


 


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 the Holder or (B) the Warrant Shares are eligible for resale by the Holder without volume or manner-of-sale limitations pursuant
to Rule 144 (assuming cashless exercise of the Warrants, and otherwise by physical delivery of a certificate (if such shares are certificated),
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 provided that payment of the aggregate
Exercise Price (other than in the instance of a cashless exercise) is received by the Company by such date, (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”) provided
that payment of the aggregate Exercise Price (other than in the instance of a cashless exercise) is received by the Company by such 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.


 






     4


     


    

  


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 (other than any such failure that is solely due to
any action or inaction by the Holder with respect to such exercise), 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.


 






     5


     


    

 


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 Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by the Holder that
    the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder
    is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation contained in this
    Section 2(e) applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together
    with any Affiliates and 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 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 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 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.

	f)	 Each certificate or notice of book entry evidencing Warrant Shares that are issued prior to the six- month anniversary of the Initial Issue Date at any time when there is no effective registration statement registering such Warrant Shares shall be imprinted with a legend in substantially the following form and consistent with the legends imprinted on certificates or book entries relating to other shares of Common Stock:







 


			THE SHARES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
                                                                             AS AMENDED (THE “ACT”), OR THE SECURITIES LAWS OF ANY STATE AND, EXCEPT AS SET FORTH IN THAT CERTAIN WARRANT TO
                                                                             PURCHASE STOCK ISSUED BY THE ISSUER TO ARMISTICE CAPITAL MASTER FUND LTD. DATED OCTOBER 27, 2021, MAY NOT BE OFFERED, SOLD, PLEDGED
                                                                             OR OTHERWISE TRANSFERRED UNLESS AND UNTIL REGISTERED UNDER SAID ACT AND LAWS OR, IN THE OPINION OF LEGAL COUNSEL IN FORM AND
                                                                             SUBSTANCE SATISFACTORY TO THE ISSUER, SUCH OFFER, SALE, PLEDGE OR OTHER TRANSFER IS EXEMPT FROM SUCH REGISTRATION.



 


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 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) Intentionally
omitted.


  


c) Subsequent
Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if during such time as this Warrant is outstanding
the Company grants, issues or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro
rata to all of 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 Limitations) 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
Limitations, then the Holder shall not be entitled to participate in such Purchase Right to such extent (or beneficial or constructive
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 Limitations).





 


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 all 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 Ownership Limits) 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 or constructive
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).

e) Fundamental
Transaction. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in one or more related transactions
effects any merger or consolidation of the Company with or into another Person, (ii) the Company, directly or indirectly, effects any
sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of its assets in one or a series
of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer (whether by the Company or another
Person) is completed pursuant to which holders of Common Stock are permitted to sell, tender or exchange their shares for other securities,
cash or property and has been accepted by the holders of 50% or more of the outstanding Common Stock, (iv) the Company, directly or indirectly,
in one or more related transactions effects any reclassification, reorganization or recapitalization of the Common Stock or any compulsory
share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property, or
(v) the Company, directly or indirectly, in one or more related transactions consummates a stock or share purchase agreement or other
business combination (including, without limitation, a reorganization, recapitalization, spin-off, 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 prior to 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 prior to 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,
if the Fundamental Transaction is not within the Company’s control, including not approved by the Company’s Board of Directors, Holder
shall only be entitled to receive from the Company or any Successor Entity, as of the date of consummation of such Fundamental Transaction,
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. “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 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 prior to the public announcement
of such Fundamental Transaction and (y) the last VWAP immediately prior to 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 and (E) a zero cost of borrow. 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 in accordance with the provisions of
this Section 3(e) pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by the Holder
(without unreasonable delay) prior to such Fundamental Transaction or 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) prior to such Fundamental Transaction, and with an exercise price which applies the exercise price hereunder to such
shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction
and the value of such shares of capital stock, such number of shares of capital stock and such exercise price being for the purpose of
protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction), and which is reasonably
satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall
succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Warrant referring
to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall
assume all of the obligations of the Company under this Warrant with the same effect as if such Successor Entity had been named as the
Company herein.

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 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 facsimile or 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; provided, however, that the
Company may satisfy this notice requirement in this Section 3(f) by filing such notice with the Commission pursuant to a Current Report
on Form 8-K or Quarterly or Annual Report.


 


ii. Notice
to Allow Exercise by Holder. If (A) the Company shall declare a dividend or other distribution (other than a stock split), (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 (excluding any granting or issuance of rights to all of the Company’s shareholders pursuant to a shareholder rights
plan), (D) the approval of any stockholders of the Company shall be required in connection with any reclassification of the Common Stock
(other than a reverse stock split), any consolidation or merger to which the Company is a party, any sale or transfer of all or substantially
all of the assets of the Company, or any compulsory share exchange whereby the Common Stock is converted into other securities, 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 facsimile or email to the Holder at its last facsimile number
or email address as it shall appear upon the Warrant Register of the Company, at least 4calendar days prior to the applicable record or
effective date hereinafter specified (unless such information is filed at least twenty calendar days prior to the applicable record with
the Commission on its EDGAR system in which case a notice shall not be required), 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.

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 and to the provisions of
Section 4.18 of the Purchase Agreement, this Warrant and all rights hereunder (including, without limitation, any registration rights)
are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent,
together with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent
or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required,
such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable,
and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing
the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. 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.


 






     11


     


    

 


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 or current public information
requirements 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, comply with the provisions of Section 4.1 of the Purchase Agreement.


 


e) Representation
by the Holder. The Holder, by the acceptance hereof, represents and warrants that it is acquiring this Warrant and, upon any exercise
hereof, will acquire the Warrant Shares issuable upon such exercise, for its own account and not with a view to or for distributing or
reselling such Warrant Shares or any part thereof in violation of the Securities Act or any applicable state securities law, except pursuant
to sales registered or exempted under the Securities Act.


 


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 prior to 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).


 






     12


     


    

 


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.


 


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) Governing
Law. 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 New York, without regard to the principles of conflicts of
law thereof. Each party agrees that all legal proceedings concerning the interpretations, enforcement and defense of the transactions
contemplated by this Warrant (whether brought against a party hereto or their respective affiliates, directors, officers, shareholders,
partners, members, employees or agents) shall be commenced exclusively in the state and federal courts sitting in the City of New York.
Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, Borough
of Manhattan for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed
herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally
subject to the jurisdiction of any such court, that such suit, action or proceeding is improper or is an inconvenient venue for such proceeding.
Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding
by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address
in effect for notices to it under this Warrant and agrees that such service shall constitute good and sufficient service of process and
notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted
by law. If either party shall commence an action, suit or proceeding to enforce any provisions of this Warrant, the prevailing party in
such action, suit or proceeding shall be reimbursed by the other party for their reasonable attorneys’ fees and other costs and
expenses incurred with the investigation, preparation and prosecution of such action or proceeding.


  






     13


     


    

 


f) Restrictions.
The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered, and the Holder does not
utilize cashless exercise, 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 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 and all notices or other communications or deliveries to be provided by the Holders hereunder including, without limitation, any Notice
of Exercise, shall be in writing and delivered personally, by facsimile or e-mail, or sent by a nationally recognized overnight courier
service, addressed to the Company, at SG Blocks, Inc., 195 Montague Street, 14th Floor, Brooklyn, NY 11201, Attention: Paul
Galvin, email address: pgalvin@sgblocks.com, or such other email address or address as the Company may specify for such purposes by notice
to the Holders. Any and all notices or other communications or deliveries to be provided by the Company hereunder shall be in writing
and delivered personally, by facsimile or e-mail, or sent by a nationally recognized overnight courier service addressed to each Holder
at the facsimile number, e-mail address or address of such Holder appearing on the books of the Company. Any notice or other communication
or deliveries hereunder shall be deemed given and effective on the earliest of (i) the time of transmission, if such notice or communication
is delivered via facsimile at the facsimile number or via e-mail at the e-mail address set forth in this Section prior to 5:30 p.m. (New
York City time) on any date, (ii) the next Trading Day after the date of transmission, if such notice or communication is delivered via
facsimile at the facsimile number or via e-mail at the e-mail address set forth in this Section on a day that is not a Trading Day or
later than 5:30 p.m. (New York City time) on any Trading Day, (iii) the second Trading Day following the date of mailing, if sent by U.S.
nationally recognized overnight courier service, or (iv) upon actual receipt by the party to whom such notice is required to be given.
To the extent that any notice provided hereunder constitutes, or contains, material, non-public information regarding the Company or any
Subsidiaries, the Company shall simultaneously file such notice with the Commission pursuant to a Current Report on Form 8-K.


 


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.


  






     14


     


    

 


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.
