Exhibit 4.2


 


WARRANT AGENT AGREEMENT


 


This Warrant Agent Agreement
(this “Warrant Agreement”), dated as of [__], 2021 (the “Issuance Date”) between Unicycive Therapeutics,
Inc., a company incorporated under the laws of the State of Delaware (the “Company”), and Philadelphia Stock Transfer,
Inc. (the “Warrant Agent”).


 


WHEREAS, pursuant to the terms
of that certain Underwriting Agreement (“Underwriting Agreement”), dated [__], 2021, by and among the Company and Roth
Capital Partners, LLC, as representatives of the several underwriters set forth therein, the Company is engaged in a public offering (the
“Offering”) of up to ____ Units, each Unit consisting of one share (the “Shares”) of common stock,
par value $0.001 per share (the “Common Stock”) of the Company and one-half Warrant (the “Warrants”)
to purchase one share of Common Stock (such shares of Common Stock underlying the Warrants, the “Warrant Shares”);


 


WHEREAS, the Company has filed
with the Securities and Exchange Commission (the “Commission”) a Registration Statement on Form S-1 (File No. 333-256367)
(as the same may be amended from time to time, the “Registration Statement”), for the registration under the Securities
Act of 1933, as amended (the “Securities Act”), of the Shares, the Warrants and Warrant Shares, and such Registration
Statement was declared effective on [__], 2021;


 


WHEREAS, the Company desires
the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in accordance with the terms set forth
in this Warrant Agreement in connection with the issuance, registration, transfer, exchange and exercise of the Warrants;


 


WHEREAS, the Company desires
to provide for the 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; and


 


WHEREAS, all acts and things
have been done and performed which are necessary to make the Warrants the valid, binding and legal obligations of the Company, and to
authorize the execution and delivery of this Warrant 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 with respect to the Warrants, and the Warrant Agent hereby accepts such
appointment and agrees to perform the same in accordance with the express terms and conditions set forth in this Warrant Agreement (and
no implied terms or conditions).


 


2. Warrants.


 


2.1. Form of Warrants.
The Warrants shall be registered securities and shall be evidenced by a global certificate (“Global Certificate”) in
the form of Exhibit A to this Warrant Agreement, which shall be deposited on behalf of the Company with a custodian for
The Depository Trust Company (“DTC”) and registered in the name of Cede & Co., a nominee of DTC. If DTC 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. In the event that the Warrants are not eligible for, or it is no longer necessary to have
the Warrants available in, book-entry form, the Company may instruct the Warrant Agent to provide written instructions to DTC to deliver
to the Warrant Agent for cancellation the Global Certificate, and the Company shall instruct the Warrant Agent to deliver to DTC separate
certificates evidencing Warrants (“Definitive Certificates” and, together with the Global Certificate, “Warrant
Certificates”) registered as requested through the DTC system.


 






     


     


    

 


2.2. Issuance and Registration
of Warrants.


 


2.2.1. Warrant Register.
The Warrant Agent shall maintain books (“Warrant Register”) for the registration of original issuance and the registration
of transfer of the Warrants.


 


2.2.2. Issuance of Warrants.
Upon the initial issuance of the Warrants, the Warrant Agent shall issue the Global Certificate and deliver the Warrants in the DTC book-entry
settlement system in accordance with written instructions delivered to the Warrant Agent by the Company. Ownership of security entitlements
in the Warrants shall be shown on, and the transfer of such ownership shall be effected through, records maintained (i) by DTC and (ii)
by institutions that have accounts with DTC (each, a “Participant”).


 


2.2.3. Beneficial Owner;
Holder. 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 that Warrant shall be registered on the Warrant Register (the “Holder”) as the absolute owner
of such Warrant for purposes 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. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Warrant Agent
or any agent of the Company or the Warrant Agent from giving effect to any written certification, proxy or other authorization furnished
by DTC governing the exercise of the rights of a holder of a beneficial interest in any Warrant. The rights of beneficial owners in a
Warrant evidenced by the Global Certificate shall be exercised by the Holder or a Participant through the DTC system, except to the extent
set forth herein or in the Global Certificate.


 


2.2.4. Execution. The
Warrant Certificates shall be executed on behalf of the Company by any authorized officer of the Company (an “Authorized Officer”),
which need not be the same authorized signatory for all of the Warrant Certificates, either manually or by facsimile signature. The Warrant
Certificates shall be countersigned by an authorized signatory of the Warrant Agent, which need not be the same signatory for all of the
Warrant Certificates, and no Warrant Certificate shall be valid for any purpose unless so countersigned. In case any Authorized Officer
of the Company that signed any of the Warrant Certificates ceases to be an Authorized Officer of the Company before countersignature by
the Warrant Agent and issuance and delivery by the Company, such Warrant Certificates, nevertheless, may be countersigned by the Warrant
Agent, issued and delivered with the same force and effect as though the person who signed such Warrant Certificates had not ceased to
be such officer of the Company; and any Warrant Certificate may be signed on behalf of the Company by any person who, at the actual date
of the execution of such Warrant Certificate, shall be an Authorized Officer of the Company authorized to sign such Warrant Certificate,
although at the date of the execution of this Warrant Agreement any such person was not such an Authorized Officer.


 


2.2.5. Registration of Transfer.
At any time at or prior to the Expiration Date (as defined below), a transfer of any Warrants may be registered and any Warrant Certificate
or Warrant Certificates may be split up, combined or exchanged for another Warrant Certificate or Warrant Certificates evidencing the
same number of Warrants as the Warrant Certificate or Warrant Certificates surrendered. Any Holder desiring to register the transfer of
Warrants or to split up, combine or exchange any Warrant Certificate shall make such request in writing delivered to the Warrant Agent,
and shall surrender to the Warrant Agent the Warrant Certificate or Warrant Certificates evidencing the Warrants the transfer of which
is to be registered or that is or are to be split up, combined or exchanged and, in the case of registration of transfer, shall provide
a signature guarantee. Thereupon, the Warrant Agent shall countersign and deliver to the person entitled thereto a Warrant Certificate
or Warrant Certificates, as the case may be, as so requested. The Warrant Agent may require reasonable and customary payment, by the Holder
requesting a registration of transfer of Warrants or a split-up, combination or exchange of a Warrant Certificate (but, for purposes of
clarity, not upon the exercise of the Warrants and issuance of Warrant Shares to the Holder), of a sum sufficient to cover any tax or
governmental charge that may be imposed in connection with such registration of transfer, split-up, combination or exchange, together
with reimbursement to the Warrant Agent of all reasonable expenses incidental thereto.

2.2.6. Loss, Theft and Mutilation
of Warrant Certificates. Upon receipt by the Company and the Warrant Agent of evidence reasonably satisfactory to them of the loss,
theft, destruction or mutilation of a Warrant Certificate, and, in case of loss, theft or destruction, of indemnity or security in customary
form and amount, and reimbursement to the Company and the Warrant Agent of all reasonable expenses incidental thereto, and upon surrender
to the Warrant Agent and cancellation of the Warrant Certificate if mutilated, the Warrant Agent shall, on behalf of the Company, countersign
and deliver a new Warrant Certificate of like tenor to the Holder in lieu of the Warrant Certificate so lost, stolen, destroyed or mutilated.
The Warrant Agent may charge the Holder an administrative fee for processing the replacement of lost Warrant Certificates, which shall
be charged only once in instances where a single surety bond obtained covers multiple certificates. The Warrant Agent may receive compensation
from the surety companies or surety agents for administrative services provided to them.


 


2.2.7. Proxies. The Holder
of a Warrant may grant proxies or otherwise authorize any person, including the Participants and beneficial holders that may own interests
through the Participants, to take any action that a Holder is entitled to take under this Agreement or the Warrants; provided,
however, that at all times that Warrants are evidenced by a Global Certificate, exercise of those Warrants shall be effected on
their behalf by Participants through DTC in accordance the procedures administered by DTC.


 


3. Terms and Exercise of Warrants.


 


3.1. Exercise Price.
Each Warrant shall entitle the Holder, subject to the provisions of the applicable Warrant Certificate and of this Warrant Agreement,
to purchase from the Company the number of shares of Common Stock stated therein, at the price of $___ per whole share, subject to the
subsequent adjustments provided in Section 4 hereof. The term “Exercise Price” as used in this Warrant Agreement refers
to 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.
Warrants may be exercised only during the period (“Exercise Period”) commencing on [__], 2021 and terminating at 5:00
P.M., Eastern Standard Time (the “close of business”) on the fifth anniversary of the Issuance Date, [__], 2026 (“Expiration
Date”). Each Warrant not exercised on or before the Expiration Date shall become void, and all rights thereunder and all rights
in respect thereof under this Warrant Agreement shall cease at the close of business on the Expiration Date.


 


3.3. Exercise of Warrants.


 


3.3.1. Exercise and Payment.
(a) Subject to the provisions of this Warrant Agreement, a Holder (or a Participant or a designee of a Participant acting on behalf of
a Holder) may exercise Warrants by delivering to the Warrant Agent, not later than 5:00 P.M., Eastern Standard Time, on any business day
during the Exercise Period an election to purchase the Warrant Shares underlying the Warrants to be exercised (i) in the form included
in Exhibit B to this Warrant Agreement or (ii) via an electronic warrant exercise through the DTC system (each, an “Election
to Purchase”). No later than one (1) Trading Day following delivery of an Election to Purchase, the Holder (or a Participant
acting on behalf of a Holder in accordance with DTC procedures) shall: (i) (A) surrender of the Warrant Certificate evidencing the Warrants
to the Warrant Agent at its office designated for such purpose or (B) deliver the Warrants to an account of the Warrant Agent at DTC designated
for such purpose in writing by the Warrant Agent to DTC from time to time, and (ii) unless the cashless exercise procedure specified in
Section 3.3.7(b) or (c) below is permitted and specified in the applicable Notice of Exercise, deliver to the Company the Exercise Price
for each Warrant to be exercised, in lawful money of the United States of America by certified or official bank check payable to the Company
or bank wire transfer in immediately available funds to:


 


[WIRE/PAYMENT INFORMATION FOR COMPANY]


 


No ink-original Election to Purchase shall be
required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Election to Purchase form be required.
Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender the Warrants to the Company
until the Holder has purchased all of the Warrant Shares available thereunder and the Warrant has been exercised in full, in which case,
the Holder shall surrender such Warrant to the Company for cancellation within three (3) Trading Days of the date the final Election to
Purchase is delivered to the Company. Partial exercises of a 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 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 Election to Purchase within one (1) Business
Day of receipt of such notice. The Holder and any assignee, by acceptance of a 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 thereof.


 






    -3-


     


    

 


Any person so designated by the Holder (or a Participant
or designee of a Participant on behalf of a Holder) to receive Warrant Shares shall be deemed to have become holder of record of such
Warrant Shares as of the time that an appropriately completed and duly signed Election to Purchase has been delivered to the Warrant Agent,
provided that the Holder (or Participant on behalf of the Holder) makes delivery of the deliverables referenced in the immediately preceding
sentence by the date that is one (1) Trading Day after the delivery of the Election to Purchase. If the Holder (or Participant on behalf
of the Holder) fails to make delivery of such deliverables on or prior to the Trading Day following delivery of the Election to Purchase,
such Election to Purchase shall be void ab initio.


 


(b) If any of (i) the Warrants, (ii) the Election
to Purchase, or (iii) the Exercise Price therefor, is received by the Warrant Agent on any date after 5:00 P.M., Eastern Standard Time,
or on a date that is not a Trading Day, the Warrants with respect thereto will be deemed to have been received and exercised on the Trading
Day next succeeding such date. “Business day” means a day other than a Saturday or Sunday on which commercial Banks
in New York City are open for the general conduct of banking business. The “Exercise Date” will be the date on which
the materials in the foregoing sentence are received by the Warrant Agent (if by 5:00 P.M., New York City time), or the following Trading
Day (if after 5:00 P.M., New York City time), regardless of any earlier date written on the materials. If the Warrants are received or
deemed to be received after the Expiration Date, the exercise thereof will be null and void and any funds delivered to the Company will
be returned to the Holder or Participant, as the case may be, as soon as practicable. In no event will interest accrue on any funds deposited
with the Company in respect of an exercise or attempted exercise of Warrants.


 


(c) If less than all the Warrants evidenced by
a surrendered Warrant Certificate are exercised, the Warrant Agent shall split up the surrendered Warrant Certificate and return to the
Holder a Warrant Certificate evidencing the Warrants that were not exercised.


 


3.3.2. Issuance of Warrant Shares.


 


(a) The Warrant Agent shall, on the Trading Day
following the Exercise Date of any Warrant, advise the Company, the transfer agent and registrar for the Company’s Common Stock,
in respect of (i) the number of Warrant Shares indicated on the Election to Purchase as issuable upon such exercise with respect to such
exercised Warrants, (ii) the instructions of the Holder or Participant, as the case may be, provided to the Warrant Agent with respect
to the delivery of the Warrant Shares and the number of Warrants that remain outstanding after such exercise and (iii) such other information
as the Company or such transfer agent and registrar shall reasonably request.


 


(b) The Company shall, by no later than 5:00 P.M.,
Eastern Standard Time, on the second Trading Day following the delivery of the Election to Purchase (provided the payment of the Exercise
Price has been submitted as required by Section 3.3.1) (such date and time, the “Delivery Time”), cause its registrar
to electronically transmit the Warrant Shares issuable upon that exercise to DTC by crediting the account of DTC or of the Participant,
as the case may be, through its Deposit/Withdrawal at Custodian (DWAC) system. If the Company fails for any reason to deliver to the Holder
the Warrant Shares subject to an Election to Purchase by the Delivery Time, 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 closing price 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 Delivery Time until such Warrant Shares are delivered or Holder
rescinds such exercise. The Company agrees to maintain a transfer agent that is a participant in the FAST program so long as this Warrant
remains outstanding and exercisable.


 


3.3.3. Valid Issuance.
All Warrant Shares issued by the Company upon the proper exercise of a Warrant in conformity with this Warrant Agreement shall be validly
issued, fully paid and non-assessable.


 






    -4-


     


    

 


3.3.4. No Fractional Exercise.
No fractional Warrant Shares will be issued upon the exercise of the Warrant. If, by reason of any adjustment made pursuant to Section
4, a Holder would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a share, the Company shall, upon
such exercise, round up or down, as applicable, to the nearest whole number the number of Warrant Shares to be issued to such Holder.


 


3.3.5. No Transfer Taxes.
Issuance of Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental expense in respect
of the issuance of such Warrant Shares, all of which taxes and expenses shall be paid by the Company, and such Warrant Shares shall be
issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however, that in the
event Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be
accompanied by an assignment form 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 Election to Purchase and all fees to the Depository Trust Company (or another established clearing corporation performing
similar functions) required for same-day electronic delivery of the Warrant Shares.


 


3.3.6. Date of Issuance.
The Company will treat an exercising Holder as a beneficial owner of the Warrant Shares as of the Exercise Date, except that, if the Exercise
Date 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 open of business on the next succeeding date on which the stock transfer books are open.


 


3.3.7. Restrictive Legend
Events. (a) The Company shall use it reasonable best efforts to maintain the effectiveness of the Registration Statement and the current
status of the prospectus included therein or to file and maintain the effectiveness of another registration statement or to file a registration
statement and another current prospectus covering the Warrants and the Warrant Shares at any time that the Warrants are exercisable. The
Company shall provide to the Warrant Agent and each Holder prompt written notice of any time that the Company is unable to deliver the
Warrant Shares via DTC transfer or otherwise without restrictive legend because (i) the Commission has issued a stop order with respect
to the Registration Statement, (ii) the Commission otherwise has suspended or withdrawn the effectiveness of the Registration Statement,
either temporarily or permanently, (iii) the Company has suspended or withdrawn the effectiveness of the Registration Statement, either
temporarily or permanently, (iv) the prospectus contained in the Registration Statement is not available for the issuance of the Warrant
Shares to the Holder or (v) otherwise (each a “Restrictive Legend Event”). To the extent that the Warrants cannot be
exercised as a result of a Restrictive Legend Event or a Restrictive Legend Event occurs after a Holder has exercised Warrants in accordance
with the terms of the Warrants but prior to the delivery of the Warrant Shares, the Company shall, at the election of the Holder, which
shall be given within five (5) days of receipt of such notice of the Restrictive Legend Event, either (A) rescind the previously submitted
Election to Purchase and the Company shall return all consideration paid by registered holder for such shares upon such rescission, or
(B) treat the attempted exercise as a cashless exercise as described in paragraph (b) below and refund the cash portion of the exercise
price to the Holder. Notwithstanding anything herein to the contrary, the Company shall not be required to make any cash payments or net
cash settlement to the Holder in lieu of delivery of the Warrant Shares.


 


(b) If a Restrictive Legend Event has occurred,
the Warrant shall only be exercisable on a cashless basis. Upon a “cashless exercise”, the Holder shall be entitled to receive
the number of Warrant Shares equal to the quotient obtained by dividing (A-B) (X) by (A), where:


 


	(A) =	the last VWAP immediately preceding the date of exercise giving rise to the applicable “cashless exercise”, as set forth in the applicable Election to Purchase (to clarify, the “last VWAP” will be the last VWAP as calculated over an entire Trading Day such that, in the event that this Warrant is exercised at a time that the Trading Market is open, the prior Trading Day’s VWAP shall be used in this calculation);
	 	 
	(B) =	the Exercise Price of the Warrant, as adjusted as set forth herein; and


 


	(X) =	the number of Warrant Shares that would be issuable upon exercise of the Warrant in accordance with the terms of the Warrant if such exercise were by means of a cash exercise rather than a cashless exercise.


 






    -5-


     


    

 


If the Warrant Shares are issued in such a cashless
exercise, the Company acknowledges and agrees that, in accordance with Section 3(a)(9) of the Securities Act, the Warrant Shares shall
take on the registered characteristics of the Warrants being exercised and the Company agrees not to take any position contrary thereto.
Upon receipt of an Election to Purchase for a cashless exercise, the Warrant Agent will promptly deliver a copy of the Election to Purchase
to the Company to confirm the number of Warrant Shares issuable in connection with the cashless exercise. The Company shall calculate
and transmit to the Warrant Agent in a written notice, and the Warrant Agent shall have no duty, responsibility or obligation under this
section to calculate, the number of Warrant Shares issuable in connection with any cashless exercise. The Warrant Agent shall be entitled
to rely conclusively on any such written notice provided by the Company, and the Warrant Agent shall not be liable for any action taken,
suffered or omitted to be taken by it in accordance with such written instructions or pursuant to this Warrant Agreement.


 


3.3.8. Disputes. In the
case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the number of Warrant Shares issuable
in connection with any exercise, the Company shall promptly deliver to the Holder the number of Warrant Shares that are not disputed.


 


3.3.9 Compensation for Buy-In
on Failure to Timely Deliver Warrant Shares Upon Exercise. In addition to any other rights available to the Holder, if the Company
fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares in accordance with the provisions of Section 3.3.2 above
pursuant to an exercise on or before the Delivery Time, and if after such date the Holder is required by its broker to purchase (in an
open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction
of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then
the Company shall (A) pay in cash to the Holder the amount, if any, by which (x) the Holder’s total purchase price (including brokerage
commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (1) the number of Warrant
Shares that the Company was required to deliver to the Holder in connection with the exercise at issue times (2) the price at which the
sell order giving rise to such purchase obligation was executed, and (B) at the option of the Holder, either reinstate the portion of
the Warrant and equivalent number of Warrant Shares for which such exercise was not honored (in which case such exercise shall be deemed
rescinded) or deliver to the Holder the number of shares of Common Stock that would have been issued had the Company timely complied with
its exercise and delivery obligations hereunder. For example, if the Holder purchases Common Stock having a total purchase price of $11,000
to cover a Buy-In with respect to an attempted exercise of shares of Common Stock with an aggregate sale price giving rise to such purchase
obligation of $10,000, under clause (A) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000.
The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request
of the Company, evidence of the amount of such loss. Nothing herein shall limit a Holder’s right to pursue any other remedies available
to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect
to the Company’s failure to timely deliver shares of Common Stock upon exercise of the Warrant as required pursuant to the terms
hereof.

3.3.10 Beneficial Ownership
Limitation. The Company shall not affect any exercise of this Warrant, and a Holder shall not have the right to exercise any portion
of a Warrant, pursuant to Section 3 or otherwise, to the extent that after giving effect to such issuance after exercise as set forth
on the applicable Election to Purchase, the Holder (together with the Holder’s Affiliates, and any other Persons acting as a group
together with the Holder or any of the Holder’s Affiliates (such Persons, “Attribution Parties”)), would beneficially
own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares
of Common Stock beneficially owned by the Holder and its Affiliates and Attribution Parties shall include the number of shares of Common
Stock issuable upon exercise of such 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, non-exercised portion of such Warrant beneficially owned by
the Holder or any of its Affiliates or Attribution Parties and (ii) exercise or conversion of the unexercised or non-converted portion
of any other securities of the Company (including, without limitation, any other Common Stock Equivalents) subject to a limitation on
conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its Affiliates or Attribution
Parties. Except as set forth in the preceding sentence, for purposes of this Section 3.3.10, 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 3.3.10 applies, the determination of whether a Warrant is exercisable (in relation to other securities owned
by the Holder together with any Affiliates and Attribution Parties) and of which portion of a 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
a Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties) and
of which portion of a 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 3.3.10, 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 such Warrant, by the Holder or its Affiliates or Attribution Parties since the date as of which such number of outstanding shares
of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% (or, upon election by a Holder prior
to the issuance of any Warrants, 9.99%) of the number of shares of the Common Stock outstanding immediately after giving effect to the
issuance of shares of Common Stock issuable upon exercise of a Warrant. The Holder, upon notice to the Company, may increase or decrease
the Beneficial Ownership Limitation provisions of this Section 3.3.10, 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 3.3.10 shall continue to apply. Any increase in the
Beneficial Ownership Limitation will not be effective until the 61st day after such notice is delivered to the Company. The
provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this
Section 3.3.10 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.


 


4. Adjustments.


 


4.1. Adjustment upon Subdivisions
or Combinations. If the Company at any time after the Issuance Date subdivides (by any stock split, stock dividend, recapitalization,
reorganization, scheme, arrangement or otherwise) its outstanding shares of Common Stock into a greater number of shares, the Exercise
Price in effect immediately prior to such subdivision will be proportionately reduced and the number of Warrant Shares will be proportionately
increased. If the Company at any time after the Issuance Date combines (by any stock split, stock dividend, recapitalization, reorganization,
scheme, arrangement or otherwise) its outstanding shares of Common Stock into a smaller number of shares, the Exercise Price in effect
immediately prior to such combination will be proportionately increased and the number of Warrant Shares will be proportionately decreased.
Any adjustment under this Section 4.1 shall become effective at the close of business on the date the subdivision or combination becomes
effective. The Company shall promptly notify Warrant Agent of any such adjustment and give specific instructions to Warrant Agent with
respect to any adjustments to the warrant register.


 


4.2. Adjustment for Other
Distributions. In the event the Company shall fix a record date for the making of a dividend or distribution to all holders of Common
Stock of any evidences of indebtedness or assets or subscription rights, options or warrants (excluding those referred to in Section 4.1
or other dividends paid out of retained earnings), then in each such case the Holder will, upon the exercise of Warrants, be entitled
to receive, in addition to the number of Warrant Shares issuable thereupon, and without payment of any additional consideration therefor,
the amount of such dividend or distribution, as applicable, which such Holder would have held on the date of such exercise had such Holder
been the holder of record of such Warrant Shares as of the date on which holders of Common Stock became entitled to receive such dividend
or distribution. Such adjustment shall be made whenever any such distribution is made and shall become effective immediately after the
record date mentioned above.

4.3. Reclassification,
Consolidation, Purchase, Combination, Sale or Conveyance. If, at any time while the Warrants are outstanding, (a) the Company, directly
or indirectly, in one or more related transactions effects any merger or consolidation of the Company with or into another person, (b)
the Company, directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or
substantially all of its assets in one or a series of related transactions, (c) any, direct or indirect, purchase offer, tender offer
or exchange offer (whether by the Company or another person) is completed pursuant to which holders of Common Stock are permitted to sell,
tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the outstanding
Common Stock (not including any Common Stock held by the other person or other persons making or party to, or associated or affiliated
with the other persons making, such purchase offer, tender offer or exchange offer), (d) the Company, directly or indirectly, in one or
more related transactions effects any reclassification, reorganization or recapitalization of the Common Stock or any compulsory share
exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property, or (e)
the Company, directly or indirectly, in one or more related transactions consummates a stock or share purchase agreement or other business
combination (including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with another person
whereby such other person acquires more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held
by the other person or other persons making or party to, or associated or affiliated with the other persons making or party to, such stock
or share purchase agreement or other business combination) (each a “Fundamental Transaction”), then, upon any subsequent
exercise of a Warrant, each Holder shall have the right to receive, for each Warrant Share that would have been issuable upon such exercise
immediately prior to the occurrence of such Fundamental Transaction, the same amount and kind of securities, cash or property, if any,
of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and any additional consideration (the
“Alternate Consideration”) receivable as a result of such Fundamental Transaction by a holder of the number of shares
of Common Stock for which each Warrant is exercisable immediately prior to such Fundamental Transaction. For purposes of any such exercise,
the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of
Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion
the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components
of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received
in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration that such Holder receives
upon any exercise of each Warrant following such Fundamental Transaction. The Company shall cause any successor entity in a Fundamental
Transaction in which the Company is not the survivor (the “Successor Entity”) and for which stockholders received any
equity securities of the Successor Entity and for which stockholders received any equity securities of the Successor Entity, to assume
in writing all of the obligations of the Company under this Warrant Agreement in accordance with the provisions of this Section 4.3 pursuant
to written agreements and shall, upon the written request of such Holder, deliver to such Holder in exchange for the applicable Warrants
created by this Warrant Agreement a security of the Successor Entity evidenced by a written instrument substantially similar in form and
substance to the Warrants which are exercisable for a corresponding number of shares of capital stock of such Successor Entity (or its
parent entity), if any, plus any Alternate Consideration, receivable as a result of such Fundamental Transaction by a holder of the number
of shares of Common Stock for which the Warrants are exercisable immediately prior to such Fundamental Transaction, and with an exercise
price which applies the Exercise Price hereunder to such shares of capital stock, if any, plus any Alternate Consideration (but taking
into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of
capital stock plus Alternative consideration after that Fundamental Transaction for the purpose of protecting the economic value of such
Warrant immediately prior to the consummation of such Fundamental Transaction). Upon the occurrence of any such Fundamental Transaction
the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions
of this Warrant Agreement and the Warrants referring to the “Company” shall refer instead to the Successor Entity), and may
exercise every right and power of the Company and shall assume all of the obligations of the Company under this Warrant Agreement and
the Warrants with the same effect as if such Successor Entity had been named as the Company herein and therein. The Company shall instruct
the Warrant Agent in writing to mail by first class mail, postage prepaid, to each Holder, written notice of the execution of any such
amendment, supplement or agreement with the Successor Entity. Any supplemented or amended agreement entered into by the successor corporation
or transferee shall provide for adjustments, which shall be as nearly equivalent as may be practicable to the adjustments provided for
in this Section 4.3. The Warrant Agent shall have no duty, responsibility or obligation to determine the correctness of any provisions
contained in such agreement or such notice, including but not limited to any provisions relating either to the kind or amount of securities
or other property receivable upon exercise of warrants or with respect to the method employed and provided therein for any adjustments,
and shall be entitled to rely conclusively for all purposes upon the provisions contained in any such agreement. The provisions of this
Section 4.3 shall similarly apply to successive reclassifications, changes, consolidations, mergers, sales and conveyances of the kind
described above.

4.4. Other Events.
If any event occurs of the type contemplated by the provisions of Section 4.1 or 4.2 but not expressly provided for by such provisions
(including, without limitation, the granting of stock appreciation rights, Adjustment Rights, phantom stock rights or other rights with
equity features to all holders of Common Stock for no consideration), then the Company's Board of Directors will, at its discretion and
in good faith, make an adjustment in the Exercise Price and the number of Warrant Shares or designate such additional consideration to
be deemed issuable upon exercise of a Warrant, so as to protect the rights of the registered Holder. No adjustment to the Exercise Price
will be made pursuant to more than one sub-section of this Section 4 in connection with a single issuance.


 


4.5. Notices of Changes
in Warrant. Upon every adjustment of the Exercise Price or the number of Warrant Shares issuable upon exercise of a Warrant, the Company
shall give prompt written notice thereof to the Warrant Agent, which notice shall state the Exercise Price resulting from such adjustment
and the increase or decrease, if any, in the number of Warrant 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 event
specified in Sections 4.1 or 4.2, then, in any such event, the Company shall give written notice to each Holder, at the last address set
forth for such holder in the Warrant Register, as of the record date or the effective date of the event. Failure to give such notice,
or any defect therein, shall not affect the legality or validity of such event. The Warrant Agent shall be entitled to rely conclusively
on, and shall be fully protected in relying on, any certificate, notice or instructions provided by the Company with respect to any adjustment
of the Exercise Price or the number of shares issuable upon exercise of a Warrant, or any related matter, and the Warrant Agent shall
not be liable for any action taken, suffered or omitted to be taken by it in accordance with any such certificate, notice or instructions
or pursuant to this Warrant Agreement. The Warrant Agent shall not be deemed to have knowledge of any such adjustment unless and until
it shall have received written notice thereof from the Company.


 


5. Restrictive Legends; Fractional Warrants.
In the event that a Warrant Certificate surrendered for transfer bears a restrictive legend, the Warrant Agent shall not register that
transfer until the Warrant Agent has received an opinion of counsel for the Company stating that such transfer may be made and indicating
whether the Warrants must also bear a restrictive legend upon that transfer. The Warrant Agent shall not be required to effect any registration
of transfer or exchange which will result in the transfer of or delivery of a Warrant Certificate for a fraction of a Warrant.


 


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


 


6.1. No Rights as Stockholder.
Except as otherwise specifically provided herein, a Holder, solely in its capacity as a holder of Warrants, shall not be entitled to vote
or receive dividends or be deemed the holder of share capital of the Company for any purpose, nor shall anything contained in this Warrant
Agreement be construed to confer upon a Holder, solely in its capacity as the registered holder of Warrants, any of the rights of a stockholder
of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification
of share capital, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights
or rights to participate in new issues of shares, or otherwise, prior to the issuance to the Holder of the Warrant Shares which it is
then entitled to receive upon the due exercise of Warrants.


 


6.2. 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 Warrant Agreement.

delinquent payments. (c) No provision of this Warrant Agreement shall require Warrant Agent to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties under this Warrant Agreement or in the exercise of its rights.

hereunder the Warrant Agent: (a) shall have no duties or obligations other than those specifically set forth herein or as may subsequently

the Warrant Agent for written instructions from the Company may, at the option of the Agent, set forth in writing any action proposed
to be taken or omitted by the Warrant Agent under this Warrant Agreement and the date on or after which such action shall be taken or
such omission shall be effective; the Warrant Agent shall not be liable for any action taken by, or omission of, the Warrant Agent in
accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less

any earlier date) unless prior to taking any such action, the Warrant Agent shall have received written instructions in response to such
application specifying the action to be taken or omitted; (i) may consult with counsel satisfactory to the Warrant Agent, including its
in-house counsel, and the advice of such counsel shall be full and complete authorization and protection in respect of any action taken,

hereunder either directly or by or through nominees, correspondents, designees, or subagents, and it shall not be liable or responsible

7.4. (a) In the absence of
gross negligence or willful or illegal misconduct on its part, the Warrant Agent shall not be liable for any action taken, suffered, or
omitted by it or for any error of judgment made by it in the performance of its duties under this Warrant Agreement. Anything in this
Warrant Agreement to the contrary notwithstanding, in no event shall Warrant Agent be liable for special, indirect, incidental, consequential
or punitive losses or damages of any kind whatsoever (including but not limited to lost profits), even if the Warrant Agent has been advised

with respect to the proper interpretation of the Warrants or the Warrant Agent’s duties under this Warrant Agreement or the rights
of the Company or of any Holder, the Warrant Agent shall not be required to act and shall not be held liable or responsible for its refusal
to act until the question or dispute has been judicially settled (and, if appropriate, it may file a suit in interpleader or for a declaratory
judgment for such purpose) by final judgment rendered by a court of competent jurisdiction, binding on all persons interested in the matter
which is no longer subject to review or appeal, or settled by a written document in form and substance satisfactory to Warrant Agent and
executed by the Company and each such Holder. In addition, the Warrant Agent may require for such purpose, but shall not be obligated
to require, the execution of such written settlement by all the Holders and all other persons that may have an interest in the settlement.


 


7.5. The Company covenants
to indemnify the Warrant Agent and hold it harmless from and against any loss, liability, claim or expense (“Loss”)
arising out of or in connection with the Warrant Agent’s duties under this Warrant Agreement, including the costs and expenses of
defending itself against any Loss, unless such Loss shall have been determined by a court of competent jurisdiction to be a result of
the Warrant Agent’s gross negligence or willful misconduct.


 


7.6. Unless terminated earlier
by the parties hereto, this Agreement shall terminate 90 days after the earlier of the Expiration Date and the date on which no Warrants
remain outstanding (the “Termination Date”). On the business day following the Termination Date, the Agent shall deliver

party or is bound; (c) this Warrant Agreement has been duly executed and delivered by the Company and constitutes the legal, valid, binding
and enforceable obligation of the Company; (d) the Warrants will comply in all material respects with all applicable requirements of law;

for an assignment or delegation of duties by Warrant Agent to any affiliate of Warrant Agent and (ii) any reorganization, merger, consolidation,
sale of assets or other form of business combination by Warrant Agent or the Company shall not be deemed to constitute an assignment of
this Warrant Agreement. (c) No provision of this Warrant Agreement may be amended, modified or waived, except in a written document signed

the purpose of curing any ambiguity, or curing, correcting or supplementing any defective provision contained herein or adding or changing

of the issuance or delivery of Warrant Shares upon the exercise of Warrants, but the Company may require the Holders to pay any transfer

account of the Company the amount of such tax or charge, if any, or shall have established to the reasonable satisfaction of the Company
and the Warrant Agent that such tax or charge, if any, has been paid.

of the Warrant Agent becomes vacant by resignation, termination 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 30 days
after it has been notified in writing of such resignation or incapacity by the Warrant Agent, then the Warrant Agent or any Holder may

it becomes necessary or appropriate or at the request of the Company, the predecessor Warrant Agent shall execute and deliver, at the
expense of the Company, an instrument transferring to such successor Warrant Agent all the authority, powers, and rights of such predecessor
Warrant Agent hereunder; and upon request of any successor Warrant Agent the Company shall make, execute, acknowledge, and deliver any

powers, rights, immunities, duties, and obligations.
