(the “Company”), and VStock Transfer, LLC, with offices at 18 Lafayette Place, Woodmere, New York (the “Warrant
Agent”). Capitalized terms used but not defined herein shall have the meanings ascribed to such terms in the Warrant
Certificate.


 


WHEREAS, the Company
is engaged in an initial public offering (the “Offering”) of units consisting of common stock of the Company,
par value $0.000001 per share (“Common Stock”), and warrants to purchase shares of Common Stock of the Company
(“Warrants”) and, in connection therewith, has determined to issue and deliver up to [____________] Warrants
to public investors in the Offering, and [___________] Warrants, bearing restrictive legends, in each case each such Warrant evidencing
the right of the holder thereof to purchase one share of Common Stock of the Company for $[____] per share, subject to adjustment
as described herein;


 


WHEREAS, the Company
has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-1,
No. 333-193315 (the “Registration Statement”) and prospectus (the “Prospectus”), for the
registration, under the Securities Act of 1933, as amended (the “Securities Act”), of the units to be sold in
the Offering, the shares of Common Stock included in the units to be sold in the Offering, the Warrants included in the units to
be sold in the Offering, and the shares of Common Stock underlying the Warrants;


 


WHEREAS, the Company
desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection with the issuance,
registration, transfer, exchange, redemption and exercise of the Warrants;


 


WHEREAS, the Company
desires to provide for the form and provisions of the Warrants, the terms upon which they shall be issued and exercised, and the
respective rights, limitation of rights and immunities of the Company, the Warrant Agent and the holders of the Warrants (the “Holders”);
and


 


WHEREAS, all acts and
things have been done and performed which are necessary to make the Warrants, when executed on behalf of the Company, countersigned
by or on behalf of the Warrant Agent, as provided herein, and delivered by the Company in the manner and for the consideration
described in the Registration Statement, the underwriting agreement for the Offering and applicable warrant, valid, legal and binding
obligations of the Company, and to authorize the execution and delivery of this Agreement.


 


NOW, THEREFORE, in
consideration of the mutual agreements herein contained, the parties hereto agree as follows:


 


1.          Appointment
of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the Company for the Warrants, and the Warrant
Agent hereby accepts such appointment and agrees to perform the same in accordance with the terms and conditions set forth in this
Agreement.


 






    	 



    	 



    

 


2.          Warrants.


 


2.1           Form
of Warrant. Each Warrant shall be (a) issued in registered form only, (b) in substantially the form of Exhibit A attached
hereto (the “Warrant Certificate”), the provisions of which are incorporated herein, (c) signed by, or bear
the facsimile signature of a duly authorized officer of the Company, and (d) signed by the Warrant Agent. In the event the person
whose facsimile signature has been placed upon any Warrant Certificate shall have ceased to serve in the capacity in which such
person signed the Warrant Certificate before such Warrant Certificate is issued, it may be issued with the same effect as if he
or she had not ceased to be such at the date of issuance. All of the Warrants shall initially be represented by one or more book-entry
certificates (each, a “Book-Entry Warrant Certificate”).


 


2.2           Effect
of Countersignature. Unless and until countersigned by the Warrant Agent pursuant to this Agreement, a Warrant shall be invalid
and of no effect and may not be exercised by the holder thereof.


 


2.3           Registration.



 


2.3.1           Warrant
Register. The Warrant Agent shall maintain books (the “Warrant Register”) for the registration of the original
issuance and the registration of transfers of the Warrants. Upon the initial issuance of the Warrants, the Warrant Agent shall
issue and register the Warrants in the names of the respective holders thereof in such denominations and otherwise in accordance
with instructions delivered to the Warrant Agent by the Company. Except as provided in this Section 2.3.1, all of the Warrants
shall initially be represented by one or more Book-Entry Warrant Certificates deposited with the Depository Trust Company (the
“Depository”) and registered in the name of Cede & Co., a nominee of the Depository. Ownership of beneficial
interests in the Book-Entry Warrant Certificates shall be shown on, and the transfer of such ownership shall be effected through,
records maintained (i) by the Depository or its nominee for each Book-Entry Warrant Certificate; (ii) by institutions that have
accounts with the Depository (such institution, with respect to a Warrant in its account, a “Participant”);
or (iii) directly on the book-entry records of the Warrant Agent with respect only to owners of beneficial interests that represent
such direct registration.


 


If the Depository subsequently
ceases to make its book-entry settlement system available for the Warrants, the Company may instruct the Warrant Agent regarding
making other arrangements for book-entry settlement within ten (10) days after the Depository ceases to make its book-entry settlement
available. In the event that the Company does not make alternative arrangements for book-entry settlement within ten (10) days,
or the Warrants are not eligible for, or it is no longer necessary to have the Warrants available in, book-entry form, the Warrant
Agent shall provide written instructions to the Depository to deliver to the Warrant Agent for cancellation each Book-Entry Warrant
Certificate, and the Company shall instruct the Warrant Agent to deliver to the Depository definitive Warrant Certificates in physical
form evidencing such Warrants.


 




    	2



    	 



    

 


At the request of any
initial purchaser of Warrants, the Warrant Agent shall deliver to such purchaser definitive Warrant Certificates in physical form,
registered in the name of such purchaser, evidencing the Warrants purchased by such initial purchaser.


 


All definitive Warrant
Certificates shall be in substantially the form of Exhibit A attached hereto.


 


2.3.2           Beneficial
Owner; Registered Holder. The term “Beneficial Owner” shall mean any person in whose name ownership of a
beneficial interest in the Warrants evidenced by a Book-Entry Warrant Certificate is recorded in the records maintained by the
Depository or its nominee. Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent
may deem and treat the person in whose name such Warrant shall be registered upon the Warrant Register (the “Registered
Holder”), as the absolute owner of such Warrant and of each Warrant represented thereby (notwithstanding any notation
of ownership or other writing on the Warrant Certificate made by anyone other than the Company or the Warrant Agent), for the purpose
of any exercise thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice
to the contrary. Any reference herein to the term Holder or Registered Holder shall include a Beneficial Owner who has received
definitive Warrant Certificates registered in its name.


 


3.          Terms
and Exercise of Warrants.


 


3.1           Warrant
Price. Each Warrant shall, when countersigned by the Warrant Agent, entitle the Registered Holder thereof, subject to the provisions
of such Warrant Certificate and of this Agreement, to purchase from the Company the number of shares of Common Stock and at the
price of $[_____] per share, subject to the adjustments provided therein. The term “Warrant Price” as used in
this Agreement shall mean the price per share at which shares of Common Stock may be purchased at the time a Warrant is exercised.


 


3.2           Duration of Warrants. A Warrant may be exercised only during the period
(the “Exercise Period”) commencing on the date of issuance thereof and on or before the Termination Date. For
purposes of this Agreement, the “Termination Date” shall have the meaning set forth in the Warrant. Each Warrant
not exercised on or before the Termination Date shall become void, and all rights thereunder and all rights in respect thereof
under this Agreement shall cease at the close of business on the Termination Date.

3.3           Exercise
of Warrants.





 


3.3.1           Payment.
Subject to the provisions of the Warrant and this Agreement, a Warrant, when countersigned by the Warrant Agent, may
be exercised by the Registered Holder thereof at any time or times on or after the Initial Exercise Date and on or before
the Termination Date by delivery to the Warrant Agent, at the office of the Warrant Agent, or at the office of its successor
as Warrant Agent, of a duly executed facsimile copy of the Notice of Exercise Form annexed to the Warrant Certificate and surrender of the Warrant
Certificate by the Holder or, in the case of a Book-Entry Warrant Certificate, a copy of the Notice
of Exercise Form annexed to the Warrant Certificate properly delivered by the Participant in accordance with the
Depository’s procedures, and (ii) within three (3) Trading Days following the date of exercise, payment in full of the
Warrant Price for each full share of Common Stock as to which the Warrant is exercised and any and all applicable taxes
(except as set forth below) due in connection with the exercise of the Warrant, the exchange of the Warrant for the shares of
Common Stock, and the issuance of such shares of Common Stock, by wire transfer or cashier’s check drawn on a United
States bank, made payable to the Company, unless the cashless exercise procedure specified in Section 2(c) of the Warrant Certificate is specified in the
applicable Notice of Exercise. When permitted by the provisions of the Warrant Certificate, the Registered Holder of any
Warrant may pay the Warrant Price by the cancellation of such number of Warrant shares as is necessary, in accordance with
the formula set forth in subsection 2(c) of the Warrant Certificate, to exercise the Warrant with respect to the maximum
number of Warrant shares purchasable pursuant to the cashless exercise procedure set forth in subsection 2(c) of the Warrant
Certificate. Partial exercises of the Warrant resulting in purchases of a portion of the total number of Warrant shares available
thereunder shall have the effect of lowering the outstanding number of Warrant shares purchasable thereunder in an amount
equal to the applicable number of Warrant shares purchased. The Holder and the Warrant Agent shall maintain records showing
the number of Warrant shares purchased and the date of such purchases and, in the case of a Book-Entry Warrant Certificate,
the Warrant Agent shall maintain records showing the notation that shall be made to the records maintained by the Depository,
its nominee for each Book-Entry Warrant Certificate, or a Participant, as appropriate, evidencing the balance, if any, of the
Warrants remaining after an exercise of Warrants. The Warrant Agent shall, by the next Trading Day
following the date of exercise of any Warrant, advise the Company and the Transfer Agent and registrar in respect of (a) the
Warrant shares issuable upon such exercise as to the number of Warrants exercised in accordance with the terms and conditions
of this Agreement, (b) the instructions of each Registered Holder or Participant, as the case may be, with respect to
delivery of the Warrant shares issuable upon such exercise, and the delivery of definitive Warrant Certificates, as
appropriate, evidencing the balance, if any, of the Warrants remaining after such exercise, (c) in case of a Book-Entry
Warrant Certificate, the notation that shall be made to the records maintained by the Depository, its nominee for each
Book-Entry Warrant Certificate, or a Participant, as appropriate, evidencing the balance, if any, of the Warrants remaining
after such exercise and (d) such other information as the Company or such transfer agent and registrar shall reasonably
require. The Warrant Agent shall deliver any objection to any Notice of Exercise Form within one (1) Trading Day of receipt
of such notice. The Holder and any assignee, by acceptance of the applicable Warrant, acknowledge and agree that, by reason
of the provisions of this paragraph, following the purchase of a portion of the Warrant shares thereunder, the number of
Warrant shares available for purchase thereunder at any given time may be less than the amount stated on the face
thereof.


 




    	4



    	 



    

 


3.3.2           Issuance
of Common Stock. Certificates for shares of Common Stock purchased pursuant to the exercise of any Warrant shall
be transmitted by the Company’s transfer agent (the “Transfer Agent”) to the Holder or the
Participant by crediting the account of the Holder’s or the Participant’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 Holder or the Participant or (B) the Warrant is being exercised via cashless exercise, and otherwise
by physical delivery to the address specified by the Holder or the Participant in the Notice of Exercise by the date that is
three (3) Trading Days after the latest of (A) the delivery to the Warrant Agent of the Notice of Exercise by the Holder or,
in the case of a Participant, the proper delivery of the Notice of Exercise by the Participant in accordance with the
Depository’s procedures, (B) surrender of the Warrant Certificate and (C) payment of the aggregate Exercise Price as
set forth above and in the Warrant Certificate (including by cashless exercise, if permitted) (such date, the
“Warrant Share Delivery Date”). It is hereby understood that if an effective registration
statement is not available at the time a Notice of Exercise is delivered by
a Holder or a Participant to the Warrant Agent, the Warrant Agent shall require an opinion of
counsel prior to delivery of the Warrant shares via DWAC. 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. If the Company fails for any reason to deliver to the Holder certificates
evidencing 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 certificates are delivered or Holder rescinds such exercise. If the Warrants are not
delivered by the Warrant Share Delivery Date, the Warrant Agent shall immediately notify the Company of the untimely
delivery, the Warrant Share Delivery Date and the date of the delivery of the Warrant shares to facilitate the
Company’s payment of any damages associated therewith. For purposes of this Section 3.3.2, the certificates evidencing
the Warrant shares subject to a Notice of Exercise shall include delivery through book-entry records.


 


3.3.3           Delivery
of New Warrants Upon Exercise. If the Warrant shall have been exercised in part, the Warrant Agent shall, upon surrender
of the Warrant Certificate, deliver to the Holder a new Warrant Certificate, which may be in electronic form, evidencing the
rights of the Holder to purchase the unpurchased Warrant shares called for by the Warrant, which new Warrant shall in
all other respects be identical with the surrendered Warrant.


 


3.3.4           Rescission
Rights.  If the Transfer Agent does not transmit to the Holder a certificate or the certificates representing the
Warrant shares pursuant to Section 2(d)(i) of the Warrant Certificate by the Warrant Share Delivery Date, then the Holder will
have the right to rescind such exercise.


 


3.3.5           Charges,
Taxes and Expenses. Issuance of certificates for Warrant shares shall be made without charge to the Holder for any issue or
transfer tax or other incidental expense in respect of the issuance of such certificate, all of which taxes and expenses shall
be paid by the Company, and such certificates shall be issued in the name of the Holder or in such name or names as may be directed
by the Holder; provided, however, that in the event certificates for Warrant shares are to be issued in a name other than
the name of the Holder, the Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached to the Warrant
Certificate 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.


 




    	5



    	 



    

 


3.3.6           Valid Issuance. All shares of Common Stock issued upon the proper exercise
or surrender of a Warrant in conformity with this Agreement shall be validly issued, fully paid and nonassessable.


 


3.3.7           Date
of Issuance. Each person or entity in whose name any such certificate for shares of Common Stock is issued shall, for all purposes,
be deemed to have become the holder of record of such shares on the date on which the Warrant was surrendered and payment of the
Warrant Price was made, irrespective of the date of delivery of such certificate, except that, if the date of such surrender and
payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder
of such shares at the close of business on the next succeeding date on which the stock transfer books are open. The Company will
not close its stockholder books or records in any manner which prevents the timely exercise of the Warrants, pursuant to the terms
thereof.


 


3.3.8           Holder’s
Exercise Limitations. A Holder shall not have the right to exercise any portion of the Warrant, and neither the Warrant Agent
nor the Company shall be obligated to effect any exercise of the Warrant 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. 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 the 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 the 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 Equivalent) 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, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934,
as amended (the “Exchange Act”), and the rules and regulations promulgated thereunder, it being acknowledged
by the Holder that neither the Warrant Agent nor the Company is 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 applies, the determination of whether the Warrant is exercisable
(in relation to other securities owned by the Holder together with any Affiliates) and of the portion of the Warrant that 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 that the Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates)
with respect to the portion of the Warrant exercised as set forth in the Notice of Exercise, in each case subject to the Beneficial
Ownership Limitation, and neither the Warrant Agent nor the Company shall have any 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, 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 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
the 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 the Warrant. The Holder, upon not less
than 61 days’ prior notice to the Warrant Agent, may increase or decrease the Beneficial Ownership Limitation provisions
of this section. Any such increase or decrease will not be effective until the 61st day after such notice is delivered to the Warrant
Agent and 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 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 the Warrant.

4.          Adjustments.


 


4.1           Notices
of Changes in Warrant. Potential adjustments are set forth in the Warrant Certificate. Upon every adjustment of
the Warrant Price or the number of shares issuable upon exercise of a Warrant, the Company shall give written notice thereof
to the Warrant Agent, which notice shall state the Warrant Price resulting from such adjustment and the increase or decrease,
if any, in the number of shares purchasable at such price upon the exercise of a Warrant, setting forth in reasonable detail
the method of calculation and the facts upon which such calculation is based. Upon the occurrence of any such adjustment, and
upon notice from the Company to the Warrant Agent, the Warrant Agent shall give written notice to each Warrant holder, at
the last address set forth for such holder in the Warrant Register, of the record date or the effective date of the event
and setting forth a brief statement of facts requiring such adjustment. Failure to give such notice, or any defect therein,
shall not affect the legality or validity of such event.


 


4.2           Notice
to Allow Exercise by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on the
Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the
Company shall authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or purchase any shares
of capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection
with any reclassification of the Common Stock, any consolidation or merger to which the Company is a party, any sale or transfer
of all or substantially all of the assets of the Company, 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 20 calendar days prior to the applicable record or
effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend,
distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common
Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the
date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or
close, and (z) the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their
shares of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger,
sale, transfer or share exchange; provided that the failure to mail such notice or any defect therein or in the mailing
thereof shall not affect the validity of the corporate action required to be specified in such notice. To the extent that any notice
provided hereunder 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 the Warrants 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.


 






    	7



    	 



    

 


4.3           No
Fractional Shares. Notwithstanding any provision contained in this Agreement to the contrary, no fractional shares or scrip
representing fractional shares shall be issued upon the exercise of the Warrants.  As to any fraction of a share which
the Holder would otherwise be entitled to purchase upon such exercise, the Warrant Agent shall, at the Company’s election,
either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Warrant Price
or round up to the next whole share.


 


4.4           Form of Warrant. The form of Warrant need not be changed because of any
adjustment pursuant to this Section 4, and Warrants issued after such adjustment may state the same Warrant Price and the same
number of shares as is stated in the Warrants initially issued pursuant to this Agreement. However, the Company may, at any time,
in its sole discretion, make any change in the form of Warrant that the Company may deem appropriate and that does not affect the
substance thereof, and any Warrant thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant
or otherwise, may be in the form as so changed.


 


4.5           Calculations.
All calculations under Section 3 of the Warrant Certificate shall be made to the nearest cent or the nearest 1/100th of a share,
as the case may be. For purposes of that section, 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



    	 



    

 


5.          Transfer
and Exchange of Warrants.





 


5.1           Registration
of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant into the Warrant
Register, upon surrender of such Warrant for transfer, properly endorsed with signatures properly
guaranteed, at the principal office of the Warrant Agent or its designated agent, together
with a written assignment of the Warrant substantially in the form attached thereto 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, a new Warrant or Warrants in the name of the assignee or assignees, as applicable, representing an equal aggregate
number of Warrants shall be issued and the old Warrant shall be cancelled by the Warrant Agent. The Warrants so cancelled shall
be delivered by the Warrant Agent to the Company from time to time upon the Company’s request.


 


5.2           Procedure
for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent, together with a written request for exchange or
transfer, and, thereupon, the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the Registered
Holder of the Warrants so surrendered, representing an equal aggregate number of Warrants; provided, however, that except
as otherwise provided herein or in any Book-Entry Warrant Certificate, each Book-Entry Warrant Certificate may be transferred only
in whole and only to the Depository, to another nominee of the Depository, to a successor depository, or to a nominee of a successor
depository; provided further, however, that, in the event a Warrant surrendered for transfer bears a restrictive legend,
the Warrant Agent shall not cancel such Warrant and shall issue new Warrants in exchange therefor until the Warrant Agent has received
an opinion of counsel for the Company stating that such transfer may be made and indicating whether the new Warrants must also
bear a restrictive legend.


 


5.3           Fractional
Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange which will result in the
issuance of a warrant certificate for a fraction of a warrant.


 


5.4           Warrant
Execution and Countersignature. The Warrant Agent is hereby authorized to countersign and to deliver, in accordance with the
terms of this Agreement, the Warrants required to be issued pursuant to the provisions of this Section 5, and the Company, whenever
required by the Warrant Agent, will supply the Warrant Agent with Warrant Certificates duly executed on behalf of the Company for
such purpose.


 


6.          Other
Provisions Relating to Rights of Holders of Warrants.


 


6.1           No
Rights as Stockholder. A Warrant does not entitle the Registered Holder thereof to any of the rights of a stockholder of the
Company, including, without limitation, the right to receive dividends, or other distributions, exercise any preemptive rights
to vote or to consent or to receive notice as stockholders in respect of the meetings of stockholders or the election of directors
of the Company or any other matter.


 


6.2           Lost,
Stolen Mutilated or Destroyed Warrants. The Company covenants that upon receipt by the Company, Warrant Agent or Transfer Agent,
as applicable, of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of the 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, and upon surrender and cancellation of such
Warrant or stock certificate, if mutilated, the Warrant Agent or Transfer Agent, as applicable, 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.


 




    	9



    	 



    

 


6.3           Reservation
of Common Stock. The Company shall at all times reserve and keep available a number of its authorized but unissued shares of
Common Stock that will be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Agreement.


 


7.          Concerning
the Warrant Agent and Other Matters.


 


7.1           Payment
of Taxes. Subject to Section 3.3.5 hereof, the Company will, from time to time, promptly pay all taxes and charges that may
be imposed upon the Company or the Warrant Agent in respect of the issuance or delivery of shares of Common Stock upon the exercise
of Warrants.


 


7.2           Resignation,
Consolidation, or Merger of Warrant Agent.


 


7.2.1           Appointment
of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties and be discharged
from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the Company. If the
office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the Company shall appoint, in writing,
a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to make such appointment within a period of
thirty (30) days after it has been notified in writing of such resignation or incapacity by the Warrant Agent or by the holder
of the Warrant (who shall, with such notice, submit his, her or its Warrant for inspection by the Company), then the holder of

Agent hereunder; and, upon request of any successor Warrant Agent, the Company shall make, execute, acknowledge, and deliver any
