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 Original Issue Date and on or before the Termination Date by delivery to the Company (or such other office or agency
of the Company as it may designate by notice in writing to the registered Holder at the address of the Holder appearing on the
books of the Company) of a duly executed copy of the Notice of Exercise form annexed hereto (via facsimile or electronic mail)
and within three (3) Trading Days of the date said Notice of Exercise is delivered to the Company, the Company shall have received
payment of the aggregate Exercise Price of the shares of Common Stock thereby purchased by wire transfer to an account designated
by the Company or cashier’s check drawn on a United States bank or, if available, pursuant to the cashless exercise procedure
specified in Section 2(c) below. If the amount of payment received by the Company is less than the aggregate Exercise Price of
the shares of Common Stock being purchased, the Holder shall make payment of the deficiency within three (3) Trading Days following
notice thereof. 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 form 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 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 automatically
reduce the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares
purchased. The Holder and the Company shall maintain records showing the number of Warrant Shares purchased and the date of such
purchases. The Company shall deliver any objection to any Notice of Exercise Form within two (2) Business Days 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 equal to the lesser of (A) $4.50 and (B) the
price per share of Common Stock sold in the Company’s initial public offering of Common Stock, multiplied by 60% (as may
be adjusted hereunder, the “Exercise Price”; however, in no event shall the Exercise Price be adjusted below
$3.00).

 

    	4

     

    

 

c)        Cashless
Exercise. If at any time there is no effective registration statement registering, or no current prospectus available for,
the resale of the Warrant Shares by the Holder, then this Warrant may also be exercised, in whole or in part, at such time by means
of a “cashless exercise” in which the Holder shall be entitled to receive a number of Warrant Shares equal to the quotient
obtained by dividing [(A-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)(64) of Regulation NMS promulgated under the federal securities laws) on such Trading Day, (ii) the bid
price of the Common Stock on the principal Trading Market as reported by Bloomberg 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 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 1(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.

 

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 Certificates Upon Exercise. Certificates for shares of Common Stock purchased hereunder shall be transmitted by VStock Transfer,
LLC (the “Transfer Agent”) to the Holder by crediting the account of the Holder’ s prime broker with The
Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then
a participant in such system and either (A) there is an effective registration statement permitting the issuance of the Warrant
Shares to or resale of the Warrant Shares by the Holder or (B) the shares of Common Stock are eligible for resale by the Holder
without volume or manner-of-sale limitations pursuant to Rule 144, and otherwise by physical delivery to the address specified
by the Holder in the Notice of Exercise by the date that is five (5) Trading Days after the latest of (A) the delivery to the Company
of the Notice of Exercise, (B) and (B) payment of the aggregate Exercise Price as set forth above (including by cashless exercise,
if permitted) (such date, the “Warrant Share Delivery Date”). The Warrant Shares shall be deemed to have been
issued, and Holder or any other Person so designated to be named therein shall be deemed to have become a holder of record of such
shares for all purposes, as of the date the Warrant has been exercised, with payment to the Company of the Exercise Price (or by
cashless exercise, if permitted) and all taxes required to be paid by the Holder, if any, pursuant to Section 2(d)(vi) prior to
the issuance of such shares, having been paid.

 

    	5

     

    

 

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, at the time of delivery of the certificate or certificates representing Warrant Shares, deliver
to the Holder a new Warrant evidencing the rights of the Holder to purchase the unpurchased Warrant Shares called for by this Warrant,
which new Warrant shall in all other respects be identical with this Warrant.

 

iii.          Rescission
Rights. If the Company fails to cause the Transfer Agent to transmit to the Holder a certificate or the certificates representing
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 Certificates 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 a certificate or the certificates representing the Warrant
Shares pursuant to an exercise on or before the Warrant Share Delivery Date, and if after such date the Holder is required by its
broker to purchase (in an open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, shares
of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving
upon such exercise (a “Buy-In”), then the Company shall (A) pay in cash to the Holder the amount, if any, by
which (x) the Holder’ s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so
purchased exceeds (y) the amount obtained by multiplying (1) the number of Warrant Shares that the Company was required to deliver
to the Holder in connection with the exercise at issue times (2) the price at which the sell order giving rise to such purchase
obligation was executed, and (B) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number
of Warrant Shares for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to
the Holder the number of shares of Common Stock that would have been issued had the Company timely complied with its exercise and
delivery obligations hereunder. For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover
a Buy-In with respect to an attempted exercise 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 certificates representing shares of Common Stock
upon exercise of the Warrant as required pursuant to the terms hereof.

 

v.           No
Fractional Shares or Scrip. No fractional shares of Common Stock or scrip representing fractional shares of Common Stock shall
be issued upon the exercise of this Warrant. As to any fraction of a share of Common Stock 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 of Common Stock.

 

    	6

     

    

 

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

 

i.            In
the event the Company shall issue any Additional Shares of Common Stock (as defined below), at a price per share less than the
Exercise Price then in effect or without consideration, then the Exercise Price upon each such issuance shall be adjusted to that
price determined by multiplying the Exercise Price then in effect by a fraction:

 

(A)         the
numerator of which shall be equal to the sum of (x) the number of outstanding shares of Common Stock (assuming full exercise, conversion
or exchange of all warrants and other securities which are convertible into or exercisable or exchangeable for, and any right to
subscribe for, Common Stock) immediately prior to the issuance of such Additional Shares of Common Stock plus (y) the number of
shares of Common Stock (rounded to the nearest whole share of Common Stock) which the aggregate consideration for the total number
of such Additional Shares of Common Stock so issued would purchase at a price per share equal to the Exercise Price then in effect,
and

 

(B)         the
denominator of which shall be equal to the number of outstanding shares of Common Stock (assuming full exercise, conversion or
exchange of all warrants and other securities which are convertible into or exercisable or exchangeable for, and any right to subscribe
for, shares of Common Stock) immediately after the issuance of such Additional Shares of Common Stock.

 

ii.         “Additional
Shares of Common Stock” means all shares of Common Stock issued by the Company after the date hereof, except: (i) securities
issued (other than for cash) in connection with a merger, acquisition, or consolidation, (ii) the Warrant Shares, and (iii) shares
of Common Stock issued pursuant to the Company’s 2018 Long-Term Stock Incentive Plan.

 

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

 

    	8

     

    

 

d)        Notice
to Holder.

 

i.            Adjustment
to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall notify
the Holder via regular or electronic mail setting forth the Exercise Price after such adjustment and any resulting adjustment to
the number of Warrant Shares and setting forth a brief statement of the facts requiring such adjustment.

 

ii.         Notice
to Allow Exercise by Holder. If (A) the Company shall declare a dividend on the shares of Common Stock, (B) the Company shall
declare a special nonrecurring cash dividend on or a redemption of the shares of Common Stock, (C) the Company shall authorize
the granting to all holders of the shares of Common Stock rights or warrants to subscribe for or purchase any shares of Common
Stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection with any
reclassification of the Common Stock, any consolidation or merger to which the Company is a party, any sale or transfer of all
or substantially all of the assets of the Company, or any compulsory share exchange whereby the Common Stock is converted into
other securities, cash or property, or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or
winding up of the affairs of the Company, then, in each case, the Company shall cause to be mailed to the Holder at its last address
as it shall appear upon the Warrant Register of the Company, at least 10 calendar days prior to the applicable record or effective
date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, 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, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation,
merger, sale, transfer or Common Stock 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 Common Stock for securities, cash or other property
deliverable upon such reclassification, consolidation, merger, sale, transfer or Common Stock exchange; provided that the failure
to notify Holder or any defect therein or in the notification thereof shall not affect the validity of the corporate action required
to be specified in such notice. To the extent that any notice provided hereunder constitutes, or contains, material, non-public
information regarding the Company or any of the Company’s 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.

 

e)        Voluntary
Adjustment by Company. The Company may at any time during the term of this Warrant reduce the then current Exercise Price to
any amount and for any period of time deemed appropriate by the Board of Directors of the Company.

Section 4.          Transfer

a)        Transferability.
Subject to compliance with any applicable securities laws and the conditions set forth in Section 4(d) hereof, this Warrant and
all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part, upon surrender
of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this Warrant
substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any
transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company shall
execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the denomination
or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion
of this Warrant not so assigned, and this Warrant shall promptly be cancelled. 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 ten (10) Trading Days of the date the Holder
delivers an assignment form to the Company assigning this Warrant 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 Original
Issue Date and shall be identical with this Warrant except as to the number of Warrant Shares issuable pursuant thereto.

 

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

 

d)       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.

 

e)        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 Section 5(k).

Section 5.         Miscellaneous.

 

a)        No
Rights as Stockholder Until Exercise. This Warrant does not entitle the Holder to any voting rights, dividends or other rights
as a stockholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly set forth in
Section 3.

 

b)        Loss,
Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant
Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (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 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 is listed. The Company covenants that
all Warrant Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise
of the purchase rights represented by this Warrant and payment for such Warrant Shares in accordance herewith, be duly authorized,
validly issued, fully paid and nonassessable and free from all taxes, liens and charges created by the Company in respect of the
issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

 

Except and to the extent as waived or consented
to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate of incorporation,
as amended, or bylaws, 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) 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 (ii) 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.

 

    	11

     

    

 

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
having jurisdiction thereof.

 

e)        Jurisdiction.
The corporate laws of the State of Delaware shall govern all issues concerning the relative rights of the Company and its stockholders.
All other 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. The Company and Holder each agrees that all legal proceedings concerning the interpretations, enforcement and defense
of the transactions contemplated by this Warrant (whether brought against the Company or Holder, or their respective affiliates,
directors, officers, stockholders, partners, members, employees or agents) shall be commenced exclusively in the state and federal
courts sitting in the City of New York. The Company and Holder each 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. The Company and Holder each 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 one another 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 the Company or Holder shall commence an action, suit or proceeding to enforce any provisions of the
Warrant, then, the prevailing party in such action, suit or proceeding shall be reimbursed by the other party for its reasonable
attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of such action
or proceeding and/or incurred in connection with the preparation therefor. The Company (on its behalf and, to the extent permitted
by applicable law, on behalf of its stockholders and affiliates) and the Holder hereby irrevocably waive, to the fullest extent
permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Warrant
or any transaction contemplated hereby.

 

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 or Company
shall operate as a waiver of such right or otherwise prejudice the Holder’s or Company’s rights, powers or remedies,
notwithstanding the fact that all rights hereunder terminate on the Termination Date. If either party willfully and knowingly fails
to comply with any provision of this Warrant, which results in any material damages to the other, the first party shall pay to
the other party 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 affected party in collecting any amounts due pursuant hereto or
in otherwise enforcing any of its rights, powers or remedies hereunder.

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 shares of 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

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.

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 Original Issue Date and on or before the Termination Date by delivery to the Company (or such other office or agency
of the Company as it may designate by notice in writing to the registered Holder at the address of the Holder appearing on the
books of the Company) of a duly executed copy of the Notice of Exercise form annexed hereto (via facsimile or electronic mail)
and within three (3) Trading Days of the date said Notice of Exercise is delivered to the Company, the Company shall have received
payment of the aggregate Exercise Price of the shares of Common Stock thereby purchased by wire transfer to an account designated
by the Company or cashier’s check drawn on a United States bank or, if available, pursuant to the cashless exercise procedure
specified in Section 2(c) below. If the amount of payment received by the Company is less than the aggregate Exercise Price of
the shares of Common Stock being purchased, the Holder shall make payment of the deficiency within three (3) Trading Days following
notice thereof. 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 form 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 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 automatically
reduce the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares
purchased. The Holder and the Company shall maintain records showing the number of Warrant Shares purchased and the date of such
purchases. The Company shall deliver any objection to any Notice of Exercise Form within two (2) Business Days 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 equal to the lesser of (A) $4.50 and (B) the
price per share of Common Stock sold in the Company’s initial public offering of Common Stock multiplied by 60% (as may be
adjusted hereunder, the “Exercise Price”; however, in no event shall the Exercise Price be adjusted below $3.00).

 

    	 	4	 

     

    

 

c)           Cashless
Exercise. If at any time there is no effective registration statement registering, or no current prospectus available for,
the resale of the Warrant Shares by the Holder, then this Warrant may also be exercised, in whole or in part, at such time by means
of a “cashless exercise” in which the Holder shall be entitled to receive a number of Warrant Shares equal to the quotient
obtained by dividing [(A-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)(64) of Regulation NMS promulgated under the federal securities laws) on such Trading Day, (ii) the bid
price of the Common Stock on the principal Trading Market as reported by Bloomberg 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 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 1(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.

 

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 Certificates Upon Exercise. Certificates for shares of Common Stock purchased hereunder shall be transmitted by VStock Transfer,
LLC (the “Transfer Agent”) to the Holder by crediting the account of the Holder’ s prime broker with The
Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then
a participant in such system and either (A) there is an effective registration statement permitting the issuance of the Warrant
Shares to or resale of the Warrant Shares by the Holder or (B) the shares of Common Stock are eligible for resale by the Holder
without volume or manner-of-sale limitations pursuant to Rule 144, and otherwise by physical delivery to the address specified
by the Holder in the Notice of Exercise by the date that is five (5) Trading Days after the latest of (A) the delivery to the Company
of the Notice of Exercise, (B) and (B) payment of the aggregate Exercise Price as set forth above (including by cashless exercise,
if permitted) (such date, the “Warrant Share Delivery Date”). The Warrant Shares shall be deemed to have been
issued, and Holder or any other Person so designated to be named therein shall be deemed to have become a holder of record of such
shares for all purposes, as of the date the Warrant has been exercised, with payment to the Company of the Exercise Price (or by
cashless exercise, if permitted) and all taxes required to be paid by the Holder, if any, pursuant to Section 2(d)(vi) prior to
the issuance of such shares, having been paid.

 

    	 	5	 

     

    

 

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, at the time of delivery of the certificate or certificates representing Warrant Shares, deliver
to the Holder a new Warrant evidencing the rights of the Holder to purchase the unpurchased Warrant Shares called for by this Warrant,
which new Warrant shall in all other respects be identical with this Warrant.

 

iii.          Rescission
Rights. If the Company fails to cause the Transfer Agent to transmit to the Holder a certificate or the certificates representing
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 Certificates 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 a certificate or the certificates representing the Warrant
Shares pursuant to an exercise on or before the Warrant Share Delivery Date, and if after such date the Holder is required by its
broker to purchase (in an open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, shares
of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving
upon such exercise (a “Buy-In”), then the Company shall (A) pay in cash to the Holder the amount, if any, by
which (x) the Holder’ s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so
purchased exceeds (y) the amount obtained by multiplying (1) the number of Warrant Shares that the Company was required to deliver
to the Holder in connection with the exercise at issue times (2) the price at which the sell order giving rise to such purchase
obligation was executed, and (B) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number
of Warrant Shares for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to
the Holder the number of shares of Common Stock that would have been issued had the Company timely complied with its exercise and
delivery obligations hereunder. For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover
a Buy-In with respect to an attempted exercise 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 certificates representing shares of Common Stock
upon exercise of the Warrant as required pursuant to the terms hereof.

 

v.           No
Fractional Shares or Scrip. No fractional shares of Common Stock or scrip representing fractional shares of Common Stock shall
be issued upon the exercise of this Warrant. As to any fraction of a share of Common Stock 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 of Common Stock.

 

    	 	6	 

     

    

 

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

 

i.             In
the event the Company shall issue any Additional Shares of Common Stock (as defined below), at a price per share less than the
Exercise Price then in effect or without consideration, then the Exercise Price upon each such issuance shall be adjusted to that
price determined by multiplying the Exercise Price then in effect by a fraction:

 

(A)         the
numerator of which shall be equal to the sum of (x) the number of outstanding shares of Common Stock (assuming full exercise, conversion
or exchange of all warrants and other securities which are convertible into or exercisable or exchangeable for, and any right to
subscribe for, Common Stock) immediately prior to the issuance of such Additional Shares of Common Stock plus (y) the number of
shares of Common Stock (rounded to the nearest whole share of Common Stock) which the aggregate consideration for the total number
of such Additional Shares of Common Stock so issued would purchase at a price per share equal to the Exercise Price then in effect,
and

 

(B)         the
denominator of which shall be equal to the number of outstanding shares of Common Stock (assuming full exercise, conversion or
exchange of all warrants and other securities which are convertible into or exercisable or exchangeable for, and any right to subscribe
for, shares of Common Stock) immediately after the issuance of such Additional Shares of Common Stock.

 

ii.           “Additional
Shares of Common Stock” means all shares of Common Stock issued by the Company after the date hereof, except: (i) securities
issued (other than for cash) in connection with a merger, acquisition, or consolidation, (ii) the Warrant Shares, and (iii) shares
of Common Stock issued pursuant to the Company’s 2018 Long-Term Stock Incentive Plan.

 

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

 

    	 	8	 

     

    

 

d)           Notice
to Holder.

 

i.            Adjustment
to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall notify
the Holder via regular or electronic mail setting forth the Exercise Price after such adjustment and any resulting adjustment to
the number of Warrant Shares and setting forth a brief statement of the facts requiring such adjustment.

 

ii.          Notice
to Allow Exercise by Holder. If (A) the Company shall declare a dividend on the shares of Common Stock, (B) the Company shall
declare a special nonrecurring cash dividend on or a redemption of the shares of Common Stock, (C) the Company shall authorize
the granting to all holders of the shares of Common Stock rights or warrants to subscribe for or purchase any shares of Common
Stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection with any
reclassification of the Common Stock, any consolidation or merger to which the Company is a party, any sale or transfer of all
or substantially all of the assets of the Company, or any compulsory share exchange whereby the Common Stock is converted into
other securities, cash or property, or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or
winding up of the affairs of the Company, then, in each case, the Company shall cause to be mailed to the Holder at its last address
as it shall appear upon the Warrant Register of the Company, at least 10 calendar days prior to the applicable record or effective
date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, 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, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation,
merger, sale, transfer or Common Stock 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 Common Stock for securities, cash or other property
deliverable upon such reclassification, consolidation, merger, sale, transfer or Common Stock exchange; provided that the failure
to notify Holder or any defect therein or in the notification thereof shall not affect the validity of the corporate action required
to be specified in such notice. To the extent that any notice provided hereunder constitutes, or contains, material, non-public
information regarding the Company or any of the Company’s 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.

 

e)           Voluntary
Adjustment by Company. The Company may at any time during the term of this Warrant reduce the then current Exercise Price to
any amount and for any period of time deemed appropriate by the Board of Directors of the Company.

Section 4.            Transfer
of Warrant.

 

a)           Transferability.
Subject to compliance with any applicable securities laws and the conditions set forth in Section 4(d) hereof, this Warrant and
all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part, upon surrender
of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this Warrant
substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any
transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company shall
execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the denomination
or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion
of this Warrant not so assigned, and this Warrant shall promptly be cancelled. 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 ten (10) Trading Days of the date the Holder
delivers an assignment form to the Company assigning this Warrant 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 Original
Issue Date and shall be identical with this Warrant except as to the number of Warrant Shares issuable pursuant thereto.

 

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

 

d)           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.

 

e)           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 Section 5(k).

 

    	 	10	 

     

    

 

Section 5.           Miscellaneous.

 

a)          No
Rights as Stockholder Until Exercise. This Warrant does not entitle the Holder to any voting rights, dividends or other rights
as a stockholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly set forth in
Section 3.

 

b)          Loss,
Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant
Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (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 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 is listed. The Company covenants that
all Warrant Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise
of the purchase rights represented by this Warrant and payment for such Warrant Shares in accordance herewith, be duly authorized,
validly issued, fully paid and nonassessable and free from all taxes, liens and charges created by the Company in respect of the
issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

 

Except and to the extent as waived or consented
to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate of incorporation,
as amended, or bylaws, 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) 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 (ii) 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.

 

    	 	11	 

     

    

 

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
having jurisdiction thereof.

 

e)           Jurisdiction.
The corporate laws of the State of Delaware shall govern all issues concerning the relative rights of the Company and its stockholders.
All other 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. The Company and Holder each agrees that all legal proceedings concerning the interpretations, enforcement and defense
of the transactions contemplated by this Warrant (whether brought against the Company or Holder, or their respective affiliates,
directors, officers, stockholders, partners, members, employees or agents) shall be commenced exclusively in the state and federal
courts sitting in the City of New York. The Company and Holder each 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. The Company and Holder each 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 one another 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 the Company or Holder shall commence an action, suit or proceeding to enforce any provisions of the
Warrant, then, the prevailing party in such action, suit or proceeding shall be reimbursed by the other party for its reasonable
attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of such action
or proceeding and/or incurred in connection with the preparation therefor. The Company (on its behalf and, to the extent permitted
by applicable law, on behalf of its stockholders and affiliates) and the Holder hereby irrevocably waive, to the fullest extent
permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Warrant
or any transaction contemplated hereby.

 

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.

 

    	 	12	 

     

    

 

g)          Nonwaiver
and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder or Company
shall operate as a waiver of such right or otherwise prejudice the Holder’s or Company’s rights, powers or remedies,
notwithstanding the fact that all rights hereunder terminate on the Termination Date. If either party willfully and knowingly fails
to comply with any provision of this Warrant, which results in any material damages to the other, the first party shall pay to
the other party 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 affected party 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 required or permitted to be provided hereunder shall be in writing and
shall be deemed given and effective on the earliest of: (a) the date of transmission, if such notice or communication is delivered
via email or facsimile at the email address or facsimile number set forth below at or prior to 5:30 p.m. (New York City time) on

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 shares of 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.

 

    	 	13	 

     

    

 

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.
