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 aggregate exercise price of this Warrant, except for a nominal exercise price of $0.001 per Warrant Share, was pre-funded to the Company
on or prior to the Initial Exercise Date and, consequently, no additional consideration (other than the nominal exercise price of $0.001
per Warrant Share) shall be required to be paid by the Holder to any Person to effect any exercise of this Warrant. The Holder shall not
be entitled to the return or refund of all, or any portion, of such pre-paid aggregate exercise price under any circumstance or for any
reason whatsoever, including in the event this Warrant shall not have been exercised prior to the Termination Date. The remaining unpaid
exercise price per share of Common Stock under this Warrant shall be $0.001, subject to adjustment hereunder (the “Exercise Price”).

 

c) Cashless Exercise.
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;

 

    -3-

     

    

 

(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).

 

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) this Warrant is being exercised via cashless exercise, 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. Notwithstanding the foregoing, with respect to any Notice(s) of Exercise delivered on or prior to 12:00 p.m.
(New York City time) on the Initial Exercise Date, which may be delivered at any time after the time of execution of the Purchase Agreement,
the Company agrees to deliver the Warrant Shares subject to such notice(s) by 4:00 p.m. (New York City time) on the Initial Exercise Date
and the Initial Exercise Date shall be the Warrant Share Delivery Date for purposes hereunder.

 

    -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 (1) 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% (or, upon election by a Holder prior to the issuance of any Warrants, 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.

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 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 Limits) 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 Limits),
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
Limits)).

 

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 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 Limits),
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
Limits)).

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 and
the other Transaction Documents in accordance with the provisions of this Section 3(e) pursuant to written agreements in form and substance
reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such Fundamental Transaction and
shall, at the option of the Holder, deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by
a written instrument substantially similar in form and substance to this Warrant which is exercisable for a corresponding number of shares
of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon
exercise of this Warrant (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(g)(i) 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 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 (other than in accordance with
Article VII of the Charter), (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
5 calendar days prior to the applicable record or effective date hereinafter specified (unless such information is filed at least five
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.
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.

 

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.

 

    -10-

     

    

 

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).

 

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 Charter
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.

 

    -11-

     

    

 

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.

 

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.

 

    -12-

     

    

 

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

York City time) on any date, (ii) the next Trading Day after the date of transmission, if such notice or communication is delivered via

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.

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.

 

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

SG Blocks, Inc.

195 Montague Street, 14th Floor

Brooklyn, NY 11201

Attention: Paul Galvin

Chairman and Chief Executive Officer

 

Dear Mr. Galvin:

 

This letter (the “Agreement”)
constitutes the agreement between A.G.P./Alliance Global Partners, as lead placement agent (“A.G.P.” or the “Placement
Agent”), and SG Blocks, Inc., a company organized under the laws of the state of Delaware (the “Company”),
that the Placement Agent shall serve as the placement agent for the Company, on a “reasonable best efforts” basis, in connection
with the proposed placement (the “Placement”) of (i) shares of common stock, par value, $0.01 per share (the “Shares”),
(ii) Series A warrants to purchase three-fifths of one share of common stock (“Warrants”) and (iii) Pre-Funded warrants
to purchase one share of common stock (the “Pre-Funded Warrants” and together with the Warrants, the “Warrants”).
The Warrants will be immediately exercisable and terminate five years following issuance and are
exercisable at an exercise price of $4.80 per share, subject to adjustment as set forth therein. The Pre-Funded Warrants will be immediately
exercisable and will expire when exercised in full and are exercisable at an exercise price
of $0.001 per share, subject to adjustment as set forth therein. The Shares, Warrants and the shares of common stock issuable upon
exercise of the Warrants are collectively referred to as the “Securities”). The Securities actually placed by the Placement
Agent are referred to herein as the “Placement Agent Securities.” The Shares and the Pre-Funded Warrants shall be offered
and sold under the Company’s registration statement on Form S-3 (File No. 333-228882) (the “Registration Statement”),
and the Warrants shall be offered and sold in reliance upon exemption from the registration requirements of Section 5 of the Securities
Act contained in Section 4(a)(2) thereof and/or Regulation D thereunder. The documents executed and delivered by the Company and the Purchasers
(as defined below), as applicable, in connection with the Placement, including, without limitation, a securities purchase agreement (the
“Purchase Agreement”) and Warrant certificates, shall be collectively referred to herein as the “Transaction
Documents.”

 

The Shares, Pre-Funded Warrants
and Warrants shall be sold to the Purchasers for a purchase price of $3.65 per Share and Warrant or $3.649per Pre-Funded Warrant and Warrant.
The Placement Agent may retain other brokers or dealers to act as sub-agents or selected-dealers on its behalf in connection with the
Placement.

 

The terms of the Placement
shall be mutually agreed upon by the Company and the purchasers listed in the Purchase Agreement (each, a “Purchaser”
and collectively, the “Purchasers”), and nothing herein shall imply that the Placement Agent would have the power or
authority to bind the Company or any Purchaser, or shall imply that the Company has an obligation to issue any Securities or complete
the Placement. The Company expressly acknowledges and agrees that the Placement Agent’s obligations hereunder are on a reasonable
best efforts basis only and that the execution of this Agreement does not constitute a commitment by the Placement Agent to purchase the
Securities and does not ensure the successful placement of the Securities or any portion thereof or the success of the Placement Agent
with respect to securing any other financing on behalf of the Company. Certain affiliates of the Placement Agent may participate in the
Placement by purchasing some of the Placement Agent Securities. The sale of Placement Agent Securities to any Purchaser will be evidenced
by the Purchase Agreement between the Company and such Purchaser, in a form reasonably acceptable to the Company and the Purchaser. Capitalized
terms that are not otherwise defined herein have the meanings given to such terms in the Purchase Agreement. Prior to the signing of any
Purchase Agreement, officers of the Company will be available to answer inquiries from prospective Purchasers.

SECTION 1. REPRESENTATIONS
AND WARRANTIES OF THE COMPANY; COVENANTS OF THE COMPANY.

 

A.
Representations of the Company. With respect to the Placement Agent Securities, each of the representations and warranties and
covenants (together with any related disclosure schedules thereto) made by the Company to the Purchasers
in the Purchase Agreement in connection with the Placement, is hereby incorporated herein by reference into this Agreement (as though
fully restated herein) and is, as of the date of this Agreement and as of the Closing Date, hereby made to, and in favor of, the Placement
Agent. In addition to the foregoing, the Company represents and warrants that, to its knowledge, there are no affiliations with any FINRA
member firm participating in the Placement among the Company’s officers, directors or, to the Company’s knowledge, any five
percent (5.0%) or greater stockholder of the Company.

 

B. Covenants of the Company.
The Company covenants and agrees to continue to retain (i) a firm of independent PCAOB registered public accountants for a period of at
least two (2) years after the Closing Date and (ii) a competent transfer agent with respect to the Placement Agent Securities for a period
of two (2) years after the Closing Date.

 

SECTION 2. REPRESENTATIONS
OF THE PLACEMENT AGENT. The Placement Agent represents and warrants that it (i) is a member in good standing of the Financial Industry
Regulatory Authority (“FINRA”), (ii) is registered as a broker/dealer under the Securities Exchange Act of 1934, as
amended (the “Exchange Act”), (iii) is licensed as a broker/dealer under the laws of the United States of America,
applicable to the offers and sales of the Placement Agent Securities by the Placement Agent, (iv) is and will be a corporate body validly
existing under the laws of its place of incorporation, and (v) has full power and authority to enter into and perform its obligations
under this Agreement. The Placement Agent will immediately notify the Company in writing of any change in its status with respect to subsections
(i) through (v) above. The Placement Agent covenants that it will use its reasonable best efforts to conduct the Placement hereunder in
compliance with the provisions of this Agreement and the requirements of applicable law.

 

SECTION 3. COMPENSATION.

 

A. Cash Fees. In consideration
of the services to be provided for hereunder, the Company shall pay to the Placement Agent or its respective designees a total cash fee
equal to seven percent (7.0%) of gross proceeds from the Placement of the total amount of Placement Agent Securities sold by the Placement
Agent. In addition, the Company shall pay the Placement Agent a non-accountable expense allowance of one-half percent (0.5%) of gross
proceeds from the Placement of the total amount of Placement Agent Securities sold by the Placement Agent. A.G.P. reserves the right to
reduce any item of compensation or adjust the terms thereof as specified herein in the event that a determination shall be made by FINRA
to the effect that the Placement Agent’s aggregate compensation is in excess of FINRA Rules or that the terms thereof require adjustment.

 

SECTION 4. EXPENSES.
The Company agrees to pay all costs, fees and expenses incurred by the Company in connection with the performance of its obligations hereunder
and in connection with the transactions contemplated hereby, including, without limitation: (i) all expenses incident to the issuance,
delivery and qualification of the Securities (including all printing and engraving costs); (ii) all fees and expenses of the registrar
and transfer agent of the Shares; (iii) all necessary issue, transfer and other stamp taxes in connection with the issuance and sale of
the Placement Agent Securities; (iv) all fees and expenses of the Company’s counsel, independent public or certified public accountants
and other advisors; (v) all costs and expenses incurred in connection with the preparation, printing, filing, shipping and distribution
of the Registration Statement (including financial statements, exhibits, schedules, consents and certificates of experts), the Base Prospectus
and the Prospectus Supplement, and all amendments and supplements thereto, and this Agreement; (vi) all filing fees, reasonable attorneys’
fees and expenses incurred by the Company in connection with qualifying or registering (or obtaining exemptions from the qualification
or registration of) all or any part of the Securities for offer and sale under the state securities or blue sky laws or the securities
laws of any other country; and (vii) the fees and expenses associated with including the Shares on the Trading Market. Notwithstanding
the foregoing, any advance received by the Placement Agent will be reimbursed to the Company to the extent not actually incurred in compliance
with FINRA Rule 5110(g)(4)(A). The Company’s obligations to reimburse the Placement Agent for any out-of-pocket expenses actually
incurred including the fees and disbursements of A.G.P.’s counsel, shall not exceed $50,000 in the aggregate. The Placement Agent
may deduct from the net proceeds of the offering payable to the Company on the Closing Date, the expenses set forth herein to be paid
by the Company to the Placement Agent. In the event that this Agreement shall not be carried out for any reason whatsoever, within the
time specified herein or any extensions thereof pursuant to the terms herein, the Company shall be obligated to pay to the Placement Agent
their actual and accountable out-of-pocket expenses related to the transactions contemplated herein then due and payable and upon demand
the Company shall pay the full amount thereof to the Placement Agent; provided, however, that such expense payment in no
way limits or impairs the indemnification and contribution provisions of this Agreement.

 

    -2-

     

    

 

SECTION 5. INDEMNIFICATION.

 

A. To the extent permitted
by law, with respect to the Placement Agent Securities, the Company will indemnify the Placement Agent and its affiliates, stockholders,
directors, officers, employees, members and controlling persons (within the meaning of Section 15 of the Securities Act or Section 20
of the Exchange Act) against all losses, claims, damages, expenses and liabilities, as the same are incurred (including the reasonable
fees and expenses of counsel), relating to or arising out of its activities hereunder or pursuant to this Agreement, except to the extent
that any losses, claims, damages, expenses or liabilities (or actions in respect thereof) are found in a final judgment (not subject to
appeal) by a court of law to have resulted primarily and directly from the Placement Agent’s willful misconduct or gross negligence
in performing the services described herein.

 

B. Promptly after receipt
by the Placement Agent of notice of any claim or the commencement of any action or proceeding with respect to which the Placement Agent
is entitled to indemnity hereunder, the Placement Agent will promptly notify the Company in writing of such claim or of the commencement
of such action or proceeding, but failure to so notify the Company shall not relieve the Company from any obligation it may have hereunder,
except and only to the extent such failure results in the forfeiture by the Company of substantial rights and defenses. If the Company
so elects or is requested by the Placement Agent, the Company will assume the defense of such action or proceeding and will employ counsel
reasonably satisfactory to the Placement Agent and will pay the fees and expenses of such counsel. Notwithstanding the preceding sentence,
the Placement Agent will be entitled to employ its own counsel separate from counsel for the Company and from any other party in such
action if counsel for the Placement Agent reasonably determines that it would be inappropriate under the applicable rules of professional
responsibility for the same counsel to represent both the Company and the Placement Agent. In such event, the reasonable fees and disbursements
of no more than one such separate counsel will be paid by the Company, in addition to fees of local counsel. The Company will have the
right to settle the claim or proceeding, provided that the Company will not settle any such claim, action or proceeding without the prior
written consent of the Placement Agent, which will not be unreasonably withheld.

 

C. The Company agrees to notify
the Placement Agent promptly of the assertion against it or any other person of any claim or the commencement of any action or proceeding
relating to a transaction contemplated by this Agreement.

D. If for any reason the foregoing
indemnity is unavailable to the Placement Agent or insufficient to hold the Placement Agent harmless, then the Company shall contribute
to the amount paid or payable by the Placement Agent as a result of such losses, claims, damages or liabilities in such proportion as
is appropriate to reflect not only the relative benefits received by the Company on the one hand and the Placement Agent on the other,
but also the relative fault of the Company on the one hand and the Placement Agent on the other that resulted in such losses, claims,
damages or liabilities, as well as any relevant equitable considerations. The amounts paid or payable by a party in respect of losses,
claims, damages and liabilities referred to above shall be deemed to include any legal or other fees and expenses incurred in defending
any litigation, proceeding or other action or claim. Notwithstanding the provisions hereof, the liable Placement Agent’s share of
the liability hereunder shall not be in excess of the amount of fees actually received, or to be received, by the Placement Agent under
this Agreement (excluding any amounts received as reimbursement of expenses incurred by the Placement Agent).

 

E. These indemnification provisions
shall remain in full force and effect whether or not the transaction contemplated by this Agreement is completed and shall survive the
termination of this Agreement, and shall be in addition to any liability that the Company might otherwise have to any indemnified party
under this Agreement or otherwise.

 

SECTION 6. COMPANY
LOCK-UP AGREEMENTS.

 

A. Restriction on Sales
of Capital Stock. The Company, on behalf of itself and any successor entity, agrees that, without the prior written consent of the
Purchaser, which consent may be provided or withheld for any reason in Purchaser’s sole discretion, it will not, for a period beginning
on the date of this Agreement and ending on the date that is the 90th day after the Closing Date (the “Lock-Up Period”),
(i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any
option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of capital stock of
the Company or any securities convertible into or exercisable or exchangeable for shares of capital stock of the Company; (ii) file or
cause to be filed any registration statement with the Commission relating to the offering of any shares of capital stock of the Company
or any securities convertible into or exercisable or exchangeable for shares of capital stock of the Company; (iii) complete any offering
of debt securities of the Company, other than entering into a line of credit with a traditional bank or (iv) enter into any swap or other
arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of capital stock of the Company,
whether any such transaction described in clause (i), (ii), (iii) or (iv) above is to be settled by delivery of shares of capital stock
of the Company or such other securities, in cash or otherwise.

 

The restrictions contained
in this Section 6(a) (collectively, the “Restrictions”) shall not apply to (i) the Securities, (ii) the issuance by
the Company of securities of the Company pursuant to any documents, agreements or securities existing or outstanding as of the Closing
Date, provided that such existing or outstanding documents, agreements or securities have not been amended since the date of this Agreement
to increase the number of securities or to decrease the exercise price, exchange price or conversion price of securities (other than in
connection with stock splits or combinations or otherwise in accordance with their terms at the time of the Closing Date) or to extend
the term of such documents, agreements or securities, (iii) the issuance by the Company of any securities of the Company under any equity
compensation plan of the Company for services rendered to the Company; (iv) the issuance of shares of Common Stock issued by reason of
a dividend, stock split, split-up or other distribution on shares of Common Stock, (v) the issuance of shares of Common Stock or Common
Stock Equivalents issued to banks, equipment lessors or other financial institutions, or to real property lessors, pursuant to a debt
financing, equipment leasing or real property leasing transaction, (vi) shares of Common Stock or Common Stock Equivalents issued to suppliers
or third party service providers in connection with the provision of goods or services or (vii) the issuance of any securities of the
Company in connection with a merger, joint venture, licensing arrangement or any other similar non-capital raising transaction or strategic
transaction, provided that any such issuance shall only be to a Person (or to the equityholders of a Person) which is, itself or through
its subsidiaries, an operating company or an owner of an asset in a business synergistic with the business of the Company and shall provide
to the Company additional benefits in addition to the investment of funds, but shall not include a transaction in which the Company is
issuing securities primarily for the purpose of raising capital or to an entity whose primary business is investing in securities, provided
that in each of (ii) through (iv) above, the securities shall be restricted from sale during the entire Lock-Up Period.

 

    -4-

     

    

 

B. Restriction on Continuous
Offerings. Notwithstanding the restrictions contained in Section 6(a), the Company, on behalf of itself and any successor entity,
agrees that, it will not engage, for a period beginning on the date of this Agreement and ending on the date that is the 90th day after
the date of filing of the Registration Statement as set forth in Section 4.20 of the Purchase Agreement, directly or indirectly in any
“at the market” or continuous equity transaction, offer to sell, sell, contract to sell, grant any option to sell or otherwise
dispose of shares of capital stock of the Company or any securities convertible into or exercisable or exchangeable for shares of capital
stock of the Company.

 

SECTION 7. ENGAGEMENT
TERM. The Placement Agent’s engagement hereunder will be until the earlier of (i) October 29, 2021 and (ii) the Closing Date.
The date of termination of this Agreement is referred to herein as the “Termination Date.” In the event, however, in
the course of the Placement Agent’s performance of due diligence it deems it necessary to terminate the engagement, the Placement
Agent may do so prior to the Termination Date. The Company may elect to terminate the engagement hereunder for any reason prior to the
Termination Date but will remain responsible for fees pursuant to Section 3 hereof with respect to the Placement Agent Securities if sold
in the Placement and will remain responsible to reimburse expenses actually incurred and reimbursable pursuant to Section 4 hereof. Notwithstanding
anything to the contrary contained herein, the provisions concerning the Company’s obligation to pay any fees actually earned pursuant
to Section 3 hereof and any reimbursable expenses actually incurred and reimbursable pursuant to Section 4 hereof and the provisions concerning
confidentiality, indemnification and contribution contained herein will survive any expiration or termination of this Agreement. If this
Agreement is terminated prior to the completion of the Placement, all fees due to the Placement Agent as set forth in Section 3 and 4
shall be paid by the Company to the Placement Agent on or before the Termination Date (in the event such fees are earned or owed as of
the Termination Date). The Placement Agent agrees not to use any confidential information concerning the Company provided to the Placement
Agent by the Company for any purposes other than those contemplated under this Agreement.

 

SECTION 8. PLACEMENT
AGENT INFORMATION. The Company agrees that any information or advice rendered by the Placement Agent in connection with this engagement
is for the confidential use of the Company only in their evaluation of the Placement and, except as otherwise required by law, the Company
will not disclose or otherwise refer to the advice or information in any manner without the Placement Agent’s prior written consent.

 

SECTION 9. NO FIDUCIARY
RELATIONSHIP. This Agreement does not create, and shall not be construed as creating rights enforceable by any person or entity not
a party hereto, except those entitled hereto by virtue of the indemnification provisions hereof. The Company acknowledges and agrees that
the Placement Agent is not and shall not be construed as a fiduciary of the Company and shall have no duties or liabilities to the equity
holders or the creditors of the Company or any other person by virtue of this Agreement or the retention of the Placement Agent hereunder,
all of which are hereby expressly waived.

(i) The representations and

do not include any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to

Company in writing or orally. Any such oral notice shall be confirmed promptly thereafter in writing.

 

SECTION 11. GOVERNING
LAW. This Agreement will be governed by, and construed in accordance with, the laws of the State of New York applicable to agreements
made and to be performed entirely in such State, without regard to principles of conflicts of law. This Agreement may not be assigned
by either party without the prior written consent of the other party. This Agreement shall be binding upon and inure to the benefit of
the parties hereto, and their respective successors and permitted assigns. Any right to trial by jury with respect to any dispute arising
under this Agreement or any transaction or conduct in connection herewith is waived. Any dispute arising under this Agreement may be brought

courts. Each party hereto hereby irrevocably waives personal service of process and consents to process being served in any such suit,
action or proceeding by delivering a copy thereof via overnight delivery (with evidence of delivery) to such party at the address in effect
for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice
thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. If either
party shall commence an action or proceeding to enforce any provisions of this Agreement, then the prevailing party in such action or
proceeding shall be reimbursed by the other party for its attorney’s fees and other costs and expenses incurred with the investigation,
preparation and prosecution of such action or proceeding.

 

SECTION 12. ENTIRE
AGREEMENT/MISCELLANEOUS. This Agreement embodies the entire agreement and understanding between the parties hereto, and supersedes
all prior agreements and understandings, relating to the subject matter hereof. If any provision of this Agreement is determined to be
invalid or unenforceable in any respect, such determination will not affect such provision in any other respect or any other provision
of this Agreement, which will remain in full force and effect. This Agreement may not be amended or otherwise modified or waived except
by an instrument in writing signed by the Placement Agent and the Company. The representations, warranties, agreements and covenants contained
herein shall survive the Closing Date of the Placement and delivery of the Placement Agent Securities. This Agreement may be executed
in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective
when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign
the same counterpart. In the event that any signature is delivered by facsimile transmission or a .pdf format file, such signature shall
create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect
as if such facsimile or .pdf signature page were an original thereof.

 

SECTION 13. NOTICES.
Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and shall
