WHEREAS,
the Company has filed with the Securities and Exchange Commission (the “Commission”) a Registration Statement,
No. 333-239658, on Form S-1 (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, Warrants
and Warrant Shares, and such Registration Statement was declared effective on July 16, 2020;


 


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

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 warrant (“Global Warrant”)
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. The
terms of the Global Warrant are incorporated herein by reference. 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 Warrant, and the Company shall instruct the Warrant Agent to deliver to DTC separate certificates
evidencing Warrants (“Definitive Certificates” and, together with the Global Warrant, “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 Warrant 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 Warrant shall be exercised by the Holder or a Participant
through the DTC system, except to the extent set forth herein or in the Global Warrant.


 




    	 



    	 



    

 


2.2.4. Delivery
of Warrant Certificate. A Holder has the right to elect at any time or from time to time a Warrant Exchange (as defined below)
pursuant to a Warrant Certificate Request Notice (as defined below). Upon written notice by a Holder to the Warrant Agent for
the exchange of some or all of such Holder’s Global Warrants for a Warrant Certificate evidencing the same number of Warrants,
which request shall be in the form attached hereto as Exhibit B (a “Warrant Certificate Request Notice”
and the date of delivery of such Warrant Certificate Request Notice by the Holder, the “Warrant Certificate Request Notice
Date” and the deemed surrender upon delivery by the Holder of a number of Global Warrants for the same number of Warrants
evidenced by a Warrant Certificate, a “Warrant Exchange”), the Warrant Agent shall promptly effect the Warrant
Exchange and shall promptly issue and deliver to the Holder a Warrant Certificate for such number of Warrants in the name set
forth in the Warrant Certificate Request Notice. Such Warrant Certificate, which shall be in the form attached hereto as Exhibit
C, shall be dated the original issue date of the Warrants, shall be manually executed by an authorized signatory of the Company
and shall be reasonably acceptable in all respects to such Holder. In connection with a Warrant Exchange, the Company agrees to
deliver, or to direct the Warrant Agent to deliver, the Warrant Certificate to the Holder within three (3) Business Days of the
Warrant Certificate Request Notice pursuant to the delivery instructions in the Warrant Certificate Request Notice (“Warrant
Certificate Delivery Date”). If the Company fails for any reason to deliver to the Holder the Warrant Certificate subject
to the Warrant Certificate Request Notice by the Warrant Certificate 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 evidenced by such Warrant Certificate (based on
the VWAP (as defined in the Warrants) of the Common Stock on the Warrant Certificate Request Notice Date), $10 per Business Day
for each Business Day after such Warrant Certificate Delivery Date until such Warrant Certificate is delivered or, prior to delivery
of such Warrant Certificate, the Holder rescinds such Warrant Exchange. The Company covenants and agrees that, upon the date of
delivery of the Warrant Certificate Request Notice, the Holder shall be deemed to be the holder of the Warrant Certificate and,
notwithstanding anything to the contrary set forth herein, the Warrant Certificate shall be deemed for all purposes to contain
all of the terms and conditions of the Warrants evidenced by such Warrant Certificate and the terms of this Agreement.


 


2.2.5. 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.


 




    	 



    	 



    

 


2.2.6. 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 Company and the Warrant Agent may require 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 Company and the Warrant
Agent of all reasonable expenses incidental thereto.


 


2.2.7. 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. The Warrant Agent may receive compensation from the surety companies
or surety agents for administrative services provided to them. In the event a Warrant Certificate is lost, stolen, destroyed or
mutilated, the Company hereby agrees to post a bond with respect to such lost, stolen, destroyed or mutilated Warrant Certificate
in customary form and amount.


 


2.2.8. 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 Warrant, 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 $1.50 per
whole share, subject to the subsequent adjustments provided in the Global Warrant. 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. A Warrant may be exercised only during the period (“Exercise Period”) commencing on the date
of issuance and ending on the Termination Date. For purposes of this Warrant Agreement, the “Termination Date”
shall have the meaning set forth in the Global 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. Exercise
and Payment. Subject to the provisions of the Global Warrant, 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 a notice of exercise of the Warrants to be exercised (i) in the form attached to
the Global Warrant or (ii) via an electronic warrant exercise through the DTC system (each, an “Election to Purchase”
and the date of such Election to Purchase, an “Exercise Date”). All other requirements for the exercise of
a Warrant shall be as set forth in the Warrant.


 


3.3.2. Issuance
of Warrant Shares. The Warrant Agent shall, by 11:00 a.m., New York City time, 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 Notice of Exercise 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. The Company shall issue the Warrant Shares in compliance
with the terms of the Warrant.


 


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.


 


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


 


3.3.5. No
Transfer Taxes. The Company shall not be required to pay any stamp or other tax or governmental charge required to be paid
in connection with any transfer involved in the issue of the Warrant Shares upon the exercise of Warrants; and in the event that
any such transfer is involved, the Company shall not be required to issue or deliver any Warrant Shares until such tax or other
charge shall have been paid or it has been established to the Company’s satisfaction that no such tax or other charge is
due.


 




    	 



    	 



    

 


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,
and for purposes of Regulation SHO, a holder whose interest in this Warrant is a beneficial interest in certificate(s) representing
this Warrant held in book-entry form through DTC shall be deemed to have exercised its interest in this Warrant upon instructing
its broker that is a DTC participant to exercise its interest in this Warrant, 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.


 


4. Adjustments.
Upon every adjustment of the Exercise Price or the number of Warrant Shares issuable upon exercise of a Warrant, the Company shall
give 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 Section 3 of the Warrant, then, in any such event, the Company shall give written notice to the Warrant
Agent. 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.


 


7. Concerning
the Warrant Agent and Other Matters.


 


7.1. Any
instructions given to the Warrant Agent orally, as permitted by any provision of this Warrant Agreement, shall be confirmed in
writing by the Company as soon as practicable. The Warrant Agent shall not be liable or responsible and shall be fully authorized
and protected for acting, or failing to act, in accordance with any oral instructions which do not conform with the written confirmation
received in accordance with this Section 7.1.


 


7.2. (a)
Whether or not any Warrants are exercised, for the Warrant Agent’s services as agent for the Company hereunder, the Company
shall pay to the Warrant Agent such fees as may be separately agreed between the Company and Warrant Agent and the Warrant Agent’s
out of pocket expenses in connection with this Warrant Agreement, including, without limitation, the fees and expenses of the
Warrant Agent’s counsel. While the Warrant Agent endeavors to maintain out-of-pocket charges (both internal and external)
at competitive rates, these charges may not reflect actual out-of-pocket costs, and may include handling charges to cover internal
processing and use of the Warrant Agent’s billing systems. (b) All amounts owed by the Company to the Warrant Agent under
this Warrant Agreement are due within 30 days of the invoice date. Delinquent payments are subject to a late payment charge of
one and one-half percent (1.5%) per month commencing 45 days from the invoice date. The Company agrees to reimburse the Warrant
Agent for any attorney’s fees and any other costs associated with collecting 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.


 






    	 



     


    

 


7.3. As
agent for the Company hereunder the Warrant Agent: (a) shall have no duties or obligations other than those specifically set forth
herein or as may subsequently be agreed to in writing by the Warrant Agent and the Company; (b) shall be regarded as making no
representations and having no responsibilities as to the validity, sufficiency, value, or genuineness of the Warrants or any Warrant
Shares; (c) shall not be obligated to take any legal action hereunder; if, however, the Warrant Agent determines to take any legal
action hereunder, and where the taking of such action might, in its judgment, subject or expose it to any expense or liability
it shall not be required to act unless it has been furnished with an indemnity reasonably satisfactory to it; (d) may rely on
and shall be fully authorized and protected in acting or failing to act upon any certificate, instrument, opinion, notice, letter,
telegram, telex, facsimile transmission or other document or security delivered to the Warrant Agent and believed by it to be
genuine and to have been signed by the proper party or parties; (e) shall not be liable or responsible for any recital or statement

failure on the part of the Company to comply with any of its covenants and obligations relating to the Warrants, including without
limitation obligations under applicable securities laws; (g) may rely on and shall be fully authorized and protected in acting
or failing to act upon the written, telephonic or oral instructions with respect to any matter relating to its duties as Warrant

authorized and directed to accept instructions with respect to the performance of its duties hereunder from the Company or counsel
to the Company, and may apply to the Company, for advice or instructions in connection with the Warrant Agent’s duties hereunder,
and the Warrant Agent shall not be liable for any delay in acting while waiting for those instructions; any applications by 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 than five business days after the date such application is sent to the Company, unless the Company shall have
consented in writing to 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; (h) 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, suffered, or omitted by it hereunder in good faith and in accordance with the advice
of such counsel; (i) may perform any of its duties hereunder either directly or by or through nominees, correspondents, designees,

designee, or subagent appointed with reasonable care by it in connection with this Warrant Agreement; (j) is not authorized, and
shall have no obligation, to pay any brokers, dealers, or soliciting fees to any person; and (k) shall not be required hereunder
to comply with the laws or regulations of any country other than the United States of America or any political subdivision thereof.








 


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 of the possibility of such losses or damages and regardless of the form of action.
Any liability of the Warrant Agent will be limited in the aggregate to the amount of fees paid by the Company hereunder. The Warrant
Agent shall not be liable for any failures, delays or losses, arising directly or indirectly out of conditions beyond its reasonable
control including, but not limited to, acts of government, exchange or market ruling, suspension of trading, work stoppages or
labor disputes, fires, civil disobedience, riots, rebellions, storms, electrical or mechanical failure, computer hardware or software
failure, communications facilities failures including telephone failure, war, terrorism, insurrection, earthquakes, floods, acts
of God or similar occurrences. (b) In the event any question or dispute arises 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 to the Company any entitlements, if any, held by the Warrant Agent under this Warrant
Agreement. The Agent’s right to be reimbursed for fees, charges and out-of-pocket expenses as provided in this Section 8

any provision of this Warrant Agreement shall be held illegal, invalid, or unenforceable by any court, this Warrant Agreement
shall be construed and enforced as if such provision had not been contained herein and shall be deemed an Agreement among the
parties to it to the full extent permitted by applicable law.


 


7.8. The
Company represents and warrants that: (a) it is duly incorporated and validly existing under the laws of its jurisdiction of incorporation;
(b) the offer and sale of the Warrants and the execution, delivery and performance of all transactions contemplated thereby (including
this Warrant Agreement) have been duly authorized by all necessary corporate action and will not result in a breach of or constitute
a default under the articles of association, bylaws or any similar document of the Company or any indenture, agreement or instrument
to which it is a 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; and (e) to the best of its knowledge, there is no litigation pending or threatened as of the
date hereof in connection with the offering of the Warrants.

under this Warrant Agreement (the “Authorized Representatives”). The Company shall, from time to time, certify
to you the names and signatures of any other persons authorized to act for the Company under this Warrant Agreement.


 


7.11. Except

or to such other address of which a party hereto has notified the other party.


 


7.12. (a)
This Warrant Agreement shall be governed by and construed in accordance with the laws of the State of New York. All actions and
proceedings relating to or arising from, directly or indirectly, this Warrant Agreement may be litigated in courts located within
the Borough of Manhattan in the City and State of New York. The Company hereby submits to the personal jurisdiction of such courts
and consents that any service of process may be made by certified or registered mail, return receipt requested, directed to the
Company at its address last specified for notices hereunder. Each of the parties hereto hereby waives the right to a trial by
jury in any action or proceeding arising out of or relating to this Warrant Agreement. (b) This Warrant Agreement shall inure
to the benefit of and be binding upon the successors and assigns of the parties hereto. This Warrant Agreement may not be assigned,
or otherwise transferred, in whole or in part, by either party without the prior written consent of the other party, which the
other party will not unreasonably withhold, condition or delay; except that (i) consent is not required 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 by both parties. The Company and the Warrant Agent may amend or supplement this Warrant Agreement without the consent of
any Holder for the purpose of curing any ambiguity, or curing, correcting or supplementing any defective provision contained herein
or adding or changing any other provisions with respect to matters or questions arising under this Agreement as the parties may
deem necessary or desirable and that the parties determine, in good faith, shall not adversely affect the interest of the Holders.
All other amendments and supplements shall require the vote or written consent of Holders of at least 50.1% of the then outstanding
Warrants, provided that adjustments may be made to the Warrant terms and rights in accordance with Section 4 without the consent
of the Holders.


 


7.13. Payment
of Taxes. 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 Warrant Shares upon the exercise of Warrants, but the Company may require
the Holders to pay any transfer taxes in respect of the Warrants or such shares. The Warrant Agent may refrain from registering
any transfer of Warrants or any delivery of any Warrant Shares unless or until the persons requesting the registration or issuance
shall have paid to the Warrant Agent for the 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.


 




    	 



    	 



    

 


7.14. Resignation
of Warrant Agent.


 


7.14.1. 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 thirty (30) days’ notice in writing to the Company, or such
shorter period of time agreed to by the Company. The Company may terminate the services of the Warrant Agent, or any successor
Warrant Agent, after giving thirty (30) days’ notice in writing to the Warrant Agent or successor Warrant Agent, or such
shorter period of time as agreed. If the office 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 apply to any court of competent jurisdiction for the appointment
of a successor Warrant Agent at the Company’s cost. Pending appointment of a successor to such Warrant Agent, either by
the Company or by such a court, the duties of the Warrant Agent shall be carried out by the Company. Any successor Warrant Agent
(but not including the initial Warrant Agent), whether appointed by the Company or by such court, shall be a person organized
and existing under the laws of any state of the United States of America, in good standing, and authorized under such laws to
exercise corporate trust powers and subject to supervision or examination by federal or state authority. After appointment, any
successor Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties, and obligations of its predecessor
Warrant Agent with like effect as if originally named as Warrant Agent hereunder, without any further act or deed, and except
for executing and delivering documents as provided in the sentence that follows, the predecessor Warrant Agent shall have no further
duties, obligations, responsibilities or liabilities hereunder, but shall be entitled to all rights that survive the termination
of this Warrant Agreement and the resignation or removal of the Warrant Agent, including but not limited to its right to indemnity
hereunder. If for any reason 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 and all instruments in writing for more fully and effectually vesting in and confirming
to such successor Warrant Agent all such authority, powers, rights, immunities, duties, and obligations.


 


7.14.2. Notice
of Successor Warrant Agent. In the event a successor Warrant Agent shall be appointed, the Company shall give notice thereof
to the predecessor Warrant Agent and the transfer agent for the Common Stock not later than the effective date of any such appointment.


 


7.14.3. Merger
or Consolidation of Warrant Agent. Any person into which the Warrant Agent may be merged or converted or with which it may
be consolidated or any person resulting from any merger, conversion or consolidation to which the Warrant Agent shall be a party
or any person succeeding to the shareowner services business of the Warrant Agent or any successor Warrant Agent shall be the
successor Warrant Agent under this Warrant Agreement, without any further act or deed. For purposes of this Warrant Agreement,
“person” shall mean any individual, firm, corporation, partnership, limited liability company, joint venture, association,
trust or other entity, and shall include any successor (by merger or otherwise) thereof or thereto.

Section
2. Exercise.

Exercise of Warrant. Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any
time or times on or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company of a duly
executed facsimile copy or PDF copy submitted by e-mail (or e-mail attachment) of the Notice of Exercise in the form annexed hereto
(the “Notice of Exercise”). Within the earlier of (i) two (2) Trading Days and (ii) the number of Trading Days
comprising the Standard Settlement Period (as defined in Section 2(d)(i) herein) following the date of exercise as aforesaid,
the Holder shall deliver the aggregate Exercise Price for the shares specified in the applicable Notice of Exercise by wire transfer
or cashier’s check drawn on a United States bank unless the cashless exercise procedure specified in Section 2(c) below
is specified in the applicable Notice of Exercise. No ink-original Notice of Exercise shall be required, nor shall any medallion
guarantee (or other type of guarantee or notarization) of any Notice of Exercise be required. Notwithstanding anything herein
to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased
all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender
this Warrant to the Company for cancellation within three (3) Trading Days of the date on which the final Notice of Exercise is
delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant
Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in
an amount equal to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing
the number of Warrant Shares purchased and the date of such purchases. The Company shall deliver any objection to any Notice of
Exercise within one (1) Business Day of receipt of such notice. The Holder and any assignee, by acceptance of this Warrant,
acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant
Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount
stated on the face hereof.


 


Notwithstanding
the foregoing in this Section 2(a), a holder whose interest in this Warrant is a beneficial interest in certificate(s) representing
this Warrant held in book-entry form through DTC (or another established clearing corporation performing similar functions), shall
effect exercises made pursuant to this Section 2(a) by delivering to DTC (or such other clearing corporation, as applicable) the
appropriate instruction form for exercise, complying with the procedures to effect exercise that are required by DTC (or such
other clearing corporation, as applicable), subject to a Holder’s right to elect to receive a Warrant in certificated form
pursuant to the terms of the Warrant Agent Agreement, in which case this sentence shall not apply.


 


b)
Exercise Price. The exercise price per share of Common Stock under this Warrant shall be $0.32, subject to adjustment hereunder
(the “Exercise Price”).


 




     


     


    

 


c)
Cashless Exercise. if at the time of exercise hereof there is no effective registration statement registering, or the prospectus
contained therein is not available for the issuance of the Warrant Shares to the Holder, then this Warrant may only be exercised,
in whole or in part, at such time by means of a “cashless exercise” in which the Holder shall be entitled to receive
a number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:


 


	 	(A)	=	as
    applicable: (i) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise if such Notice
    of Exercise is (1) both executed and delivered pursuant to Section 2(a) hereof on a day that is not a Trading Day or (2) both
    executed and delivered pursuant to Section 2(a) hereof on a Trading Day prior to the opening of “regular trading hours”
    (as defined in Rule 600(b)(68) of Regulation NMS promulgated under the federal securities laws) on such Trading Day, (ii)
    at the option of the Holder, either (y) the VWAP on the Trading Day immediately preceding the date of the applicable Notice
    of Exercise or (z) the Bid Price of the Common Stock on the principal Trading Market as reported by Bloomberg L.P. as of the
    time of the Holder’s execution of the applicable Notice of Exercise if such Notice of Exercise is executed during “regular
    trading hours” on a Trading Day and is delivered within two (2) hours thereafter (including until two (2) hours after
    the close of “regular trading hours” on a Trading Day) pursuant to Section 2(a) hereof or (iii) the VWAP on the
    date of the applicable Notice of Exercise if the date of such Notice of Exercise is a Trading Day and such Notice of Exercise
    is both executed and delivered pursuant to Section 2(a) hereof after the close of “regular trading hours” on such
    Trading Day;
	 	 	 	 
	 	(B)	=	the
    Exercise Price of this Warrant, as adjusted hereunder; and
	 	 	 	 
	 	(X)	=	the
    number of Warrant Shares that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant
    if such exercise were by means of a cash exercise rather than a cashless exercise.


 


If
Warrant Shares are issued in such a cashless exercise, the parties acknowledge and agree that in accordance with Section 3(a)(9)
of the Securities Act, the Warrant Shares shall take on the registered characteristics of the Warrants being exercised. The Company
agrees not to take any position contrary to this Section 2(c).


 


Notwithstanding
anything herein to the contrary, on the Termination Date, this Warrant shall be automatically exercised via cashless exercise
pursuant to this Section 2(c).


 


Notwithstanding
the foregoing, and without limiting the rights of the Holder under Sections 2(d)(i) and 2(d)(iv), in no event will the Company
be required to net cash settle an exercise of this Warrant.


 




     


     


    

 


d)
Mechanics of Exercise.


 


i.
Delivery of Warrant Shares Upon Exercise. The Company shall cause the Warrant Shares purchased hereunder to be transmitted
by the Transfer Agent to the Holder by crediting the account of the Holder’s or its designee’s balance account with
The Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company
is then a participant in such system and either (A) there is an effective registration statement permitting the issuance of the
Warrant Shares to or resale of the Warrant Shares by Holder or (B) this Warrant is being exercised via cashless exercise, and
otherwise by physical delivery of a certificate, registered in the Company’s share register in the name of the Holder or
its designee, for the number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the address specified
by the Holder in the Notice of Exercise by the date that is the earliest of (i) two (2) Trading Days after the delivery to the
Company of the Notice of Exercise and (ii) one (1) Trading Day after delivery of the aggregate Exercise Price to the Company (such
date, the “Warrant Share Delivery Date”). Upon delivery of the Notice of Exercise, the Holder shall be deemed
for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been
exercised, irrespective of the date of delivery of the Warrant Shares, provided that payment of the aggregate Exercise Price (other
than in the case of a cashless exercise) is received within the earlier of (i) two (2) Trading Days and (ii) the number of Trading
Days comprising the Standard Settlement Period following delivery of the Notice of Exercise. If the Company fails for any reason
to deliver to the Holder the Warrant Shares subject to a Notice of Exercise by the Warrant Share Delivery Date, the Company shall
pay to the Holder, in cash, as liquidated damages and not as a penalty, for each $1,000 of Warrant Shares subject to such exercise
(based on the VWAP of the Common Stock on the date of the applicable Notice of Exercise), $5 per Trading Day (increasing to $10
per Trading Day on the fifth Trading Day after such liquidated damages begin to accrue) for each Trading Day after such Warrant
Share Delivery Date until such Warrant Shares are delivered or Holder rescinds such exercise. The Company agrees to maintain a
transfer agent that is a participant in the FAST program so long as this Warrant remains outstanding and exercisable. As used
herein, “Standard Settlement Period” means the standard settlement period, expressed in a number of Trading
Days, on the Company’s primary Trading Market with respect to the Common Stock as in effect on the date of delivery of the
Notice of Exercise.


 


ii.
Delivery of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request
of a Holder and upon surrender of this Warrant certificate, at the time of delivery of the Warrant Shares, deliver to the Holder
a new Warrant evidencing the rights of the Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which
new Warrant shall in all other respects be identical with this Warrant.


 


iii.
Rescission Rights. If the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares pursuant
to Section 2(d)(i) by the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise.


 




     


     


    

 


iv.
Compensation for Buy-In on Failure to Timely Deliver Warrant Shares Upon Exercise. In addition to any other rights available
to the Holder, if the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares in accordance with
the provisions of Section 2(d)(i) above pursuant to an exercise on or before the Warrant Share Delivery Date, 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.


 


v.
No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise
of this Warrant. As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such exercise, the
Company shall, at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction
multiplied by the Exercise Price or round up to the next whole share.


 




     


     


    

 


vi.
Charges, Taxes and Expenses. Issuance of Warrant Shares shall be made without charge to the Holder for any issue or transfer
tax or other incidental expense in respect of the issuance of such Warrant Shares, all of which taxes and expenses shall be paid
by the Company, and such Warrant Shares shall be issued in the name of the Holder or in such name or names as may be directed
by the Holder; provided, however, that, in the event that Warrant Shares are to be issued in a name other than the
name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached hereto duly
executed by the Holder and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for
any transfer tax incidental thereto. The Company shall pay all Transfer Agent fees required for same-day processing of any Notice
of Exercise and all fees to the Depository Trust Company (or another established clearing corporation performing similar functions)
required for same-day electronic delivery of the Warrant Shares.


 


vii.
Closing of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise
of this Warrant, pursuant to the terms hereof.


 




     


     


    

 


e)
Holder’s Exercise Limitations. The Company shall not effect any exercise of this Warrant, and a Holder shall not
have the right to exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect
to such issuance after exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s
Affiliates, and any other Persons acting as a group together with the Holder or any of the Holder’s Affiliates (such Persons,
“Attribution Parties”)), would beneficially own in excess of the Beneficial Ownership Limitation (as defined
below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder and its
Affiliates and Attribution Parties shall include the number of shares of Common Stock issuable upon exercise of this Warrant with
respect to which such determination is being made, but shall exclude the number of shares of Common Stock which would be issuable
upon (i) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the Holder or any of its Affiliates
or Attribution Parties and (ii) exercise or conversion of the unexercised or nonconverted portion of any other securities of the
Company (including, without limitation, any other Common Stock Equivalents) subject to a limitation on conversion or exercise
analogous to the limitation contained herein beneficially owned by the Holder or any of its Affiliates or Attribution Parties.
Except as set forth in the preceding sentence, for purposes of this Section 2(e), beneficial ownership shall be calculated in
accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged
and accepted by the Holder that the Company is not representing to the Holder that such calculation is in compliance with Section
13(d) of the Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith.
To the extent that the limitation contained in this Section 2(e) applies, the determination of whether this Warrant is exercisable
(in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties) and of which portion
of this Warrant is exercisable shall be in the sole discretion of the Holder, and the submission of a Notice of Exercise shall
be deemed to be the Holder’s determination of whether this Warrant is exercisable (in relation to other securities owned
by the Holder together with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable, in each
case subject to the Beneficial Ownership Limitation. To ensure compliance with this restriction, each Holder shall be deemed to
represent to the Company each time it delivers a Notice of Exercise that such Notice of Exercise has not violated the restrictions
set forth in this paragraph, and the Company shall have no obligation to verify or confirm the accuracy of such determination.
In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d)
of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 2(e), in determining the
number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as reflected
in (A) the Company’s most recent periodic or annual report filed with the Commission, as the case may be, (B) a more recent
public announcement by the Company or (C) a more recent written notice by the Company or the Transfer Agent setting forth the
number of shares of Common Stock outstanding. Upon the written or oral request of a Holder, the Company shall within one Trading
Day confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number
of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the
Company, including this Warrant, by the Holder or its Affiliates or Attribution Parties since the date as of which such number
of outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% (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 this Warrant. The Holder,
upon notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 2(e), provided
that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares of the Common Stock outstanding immediately
after giving effect to the issuance of shares of Common Stock upon exercise of this Warrant held by the Holder and the provisions
of this Section 2(e) shall continue to apply. Any increase in the Beneficial Ownership Limitation will not be effective until
the 61st day after such notice is delivered to the Company. The provisions of this paragraph shall be construed and
implemented in a manner otherwise than in strict conformity with the terms of this Section 2(e) to correct this paragraph (or
any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained
or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained
in this paragraph shall apply to a successor holder of this Warrant.


 




     


     


    

 


Section
3. Certain Adjustments.


 


a)
Stock Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or
otherwise makes a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities
payable in shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company
upon exercise of this Warrant), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines
(including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or (iv) issues by
reclassification of shares of the Common Stock any shares of capital stock of the Company, then in each case the Exercise Price
shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares,
if any) outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding
immediately after such event, and the number of shares issuable upon exercise of this Warrant shall be proportionately adjusted
such that the aggregate Exercise Price of this Warrant shall remain unchanged. Any adjustment made pursuant to this Section 3(a)
shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend
or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.


 


b)
Subsequent Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time the Company
grants, issues or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata
to the record holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will
be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could
have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without
regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before
the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the
date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase
Rights (provided, however, that, to the extent that the Holder’s right to participate in any such Purchase Right would result
in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase
Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent)
and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto
would not result in the Holder exceeding the Beneficial Ownership Limitation).


 




     


     


    

 


c)
Pro Rata Distributions. During such time as this Warrant is outstanding, if the Company shall declare or make any dividend
or other distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of
capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options
by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction)
(a “Distribution”), at any time after the issuance of this Warrant, then, in each such case, the Holder shall
be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder
had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations
on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date of which a
record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of shares of Common
Stock are to be determined for the participation in such Distribution (provided, however, that, to the extent that
the Holder’s right to participate in any such Distribution would result in the Holder exceeding the Beneficial Ownership
Limitation, then the Holder shall not be entitled to participate in such Distribution to such extent (or in the beneficial ownership
of any shares of Common Stock as a result of such Distribution to such extent) and the portion of such Distribution shall be held
in abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding
the Beneficial Ownership Limitation).


 




     


     


    

 


d)
Fundamental Transaction. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in
one or more related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company
(and all of its Subsidiaries, taken as a whole), directly or indirectly, effects any sale, lease, license, assignment, transfer,
conveyance or other disposition of all or substantially all of its assets in one or a series of related transactions, (iii) any,
direct or indirect, purchase offer, tender offer or exchange offer (whether by the Company or another Person) is completed pursuant
to which holders of Common Stock are permitted to sell, tender or exchange their shares for other securities, cash or property
and has been accepted by the holders of 50% or more of the outstanding Common Stock, (iv) the Company, directly or indirectly,
in one or more related transactions effects any reclassification, reorganization or recapitalization of the Common Stock or any
compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities,
cash or property, or (v) the Company, directly or indirectly, in one or more related transactions consummates a stock or share
purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off,
merger or scheme of arrangement) with another Person or group of Persons whereby such other Person or group acquires more than
50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person or other Persons
making or party to, or associated or affiliated with the other Persons making or party to, such stock or share purchase agreement
or other business combination) (each a “Fundamental Transaction”), then, upon any subsequent exercise of this Warrant,
the Holder shall have the right to receive, for each Warrant Share that would have been issuable upon such exercise immediately
prior to the occurrence of such Fundamental Transaction, at the option of the Holder (without regard to any limitation in Section
2(e) on the exercise of this Warrant), the number of shares of Common Stock of the successor or acquiring corporation or of the
Company, if it is the surviving corporation, and any additional consideration (the “Alternate Consideration”) receivable
as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Warrant is exercisable
immediately prior to such Fundamental Transaction (without regard to any limitation in Section 2(e) on the exercise of this Warrant).
For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate
Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental
Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting
the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice
as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice
as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction. Notwithstanding
anything to the contrary, in the event of a Fundamental Transaction, the Company or any Successor Entity (as defined below) shall,
at the Holder’s option, exercisable at any time concurrently with, or within 30 days after, the consummation of the Fundamental
Transaction (or, if later, the date of the public announcement of the applicable Fundamental Transaction), purchase this Warrant
from the Holder by paying the same type or form of consideration (and in the same proportion), at the Black Scholes Value (as
defined below) of the unexercised portion of this Warrant, that is being offered and paid to the holders of Common Stock of the
Company in connection with the Fundamental Transaction, whether that consideration be in the form of cash, stock or any combination
thereof, or whether the holders of Common Stock are given the choice to receive from among alternative forms of consideration
in connection with the Fundamental Transaction; provided, however, if the Fundamental Transaction is not within
the Company’s control, including not approved by the Company’s Board of Directors, Holder shall only be entitled to
receive from the Company or any Successor Entity, as of the date of consummation of such Fundamental Transaction, the same type
or form of consideration (and in the same proportion), at the Black Scholes Value of the unexercised portion of this Warrant,
that is being offered and paid to the holders of Common Stock of the Company in connection with the Fundamental Transaction, whether
that consideration be in the form of cash, stock or any combination thereof, or whether the holders of Common Stock are given
the choice to receive from among alternative forms of consideration in connection with the Fundamental Transaction. “Black
Scholes Value” means the value of this Warrant based on the Black-Scholes Option Pricing Model obtained from the “OV”
function on Bloomberg, L.P. (“Bloomberg”) determined as of the day of consummation of the applicable Fundamental
Transaction for pricing purposes and reflecting (A) a risk-free interest rate corresponding to the U.S. Treasury rate for a period
equal to the time between the date of the public announcement of the applicable Fundamental Transaction and the Termination Date,
(B) an expected volatility equal to the 100 day volatility obtained from the HVT function on Bloomberg (determined utilizing a
365 day annualization factor) as of the Trading Day immediately following the public announcement of the applicable Fundamental
Transaction, (C) the underlying price per share used in such calculation shall be the greater of (i) the sum of the price per
share being offered in cash, if any, plus the value of any non-cash consideration, if any, being offered in such Fundamental Transaction
and (ii) the greater of (x) the last VWAP immediately prior to the public announcement of such Fundamental Transaction and (y)
the last VWAP immediately prior to the consummation of such Fundamental Transaction and (D) a remaining option time equal to the
time between the date of the public announcement of the applicable Fundamental Transaction and the Termination Date and (E) a
zero cost of borrow. The payment of the Black Scholes Value will be made by wire transfer of immediately available funds within
the later of (i) five Business Days of the Holder’s election and (ii) the date of consummation of the Fundamental Transaction.
The Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the survivor (the “Successor
Entity”) to assume in writing all of the obligations of the Company under this Warrant in accordance with the provisions
of this Section 3(d) pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by
the Holder (without unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the Holder, deliver
to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially
similar in form and substance to this Warrant which is exercisable for a corresponding number of shares of capital stock of such
Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon exercise of this
Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an
exercise price which applies the exercise price hereunder to such shares of capital stock (but taking into account the relative
value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such
number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant
immediately prior to the consummation of such Fundamental Transaction), and which is reasonably satisfactory in form and substance
to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted
for (so that from and after the date of such Fundamental Transaction, the provisions of this Warrant referring to the “Company”
shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the
obligations of the Company under this Warrant with the same effect as if such Successor Entity had been named as the Company herein.


 




     


     


    
 


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


 


f)
Notice to Holder.


 


i.
Adjustment to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the
Company shall promptly deliver to the Holder by facsimile or email a notice setting forth the Exercise Price after such adjustment
and any resulting adjustment to the number of Warrant Shares and setting forth a brief statement of the facts requiring such adjustment.


 


ii.
Notice to Allow Exercise by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever
form) on the Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common
Stock, (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 (and
all of its Subsidiaries, taken as a whole) is a party, any sale or transfer of all or substantially all of the assets of the Company,
or any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property, or (E) the Company
shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then, in each
case, the Company shall cause to be delivered by facsimile or email to the Holder at its last facsimile number or email address
as it shall appear upon the Warrant Register of the Company, at least 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 the date
as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common
Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or
share exchange; provided that the failure to deliver such notice or any defect therein or in the delivery thereof shall not affect
the validity of the corporate action required to be specified in such notice. To the extent that any notice provided in this Warrant
constitutes, or contains, material, non-public information regarding the Company or any of the Subsidiaries, the Company shall
simultaneously file such notice with the Commission pursuant to a Current Report on Form 8-K. The Holder shall remain entitled
to exercise this Warrant during the period commencing on the date of such notice to the effective date of the event triggering
such notice except as may otherwise be expressly set forth herein.


 




    	 



     


    

 


Section
4. Transfer of Warrant.


 


a)
Transferability. This Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable,
in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent, together with
a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney
and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required,
such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable,
and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant
evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. Notwithstanding anything
herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company unless the Holder
has assigned this Warrant in full, in which case, the Holder shall surrender this Warrant to the Company within three (3) Trading
Days of the date on which the Holder delivers an assignment form to the Company assigning this Warrant in full. The Warrant, if
properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Warrant Shares without having a
new Warrant issued.


 


b)
New Warrants. If this Warrant is not held in global form through DTC (or any successor depositary), this Warrant may be
divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together with a written
notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney.
Subject to compliance with Section 4(a), as to any transfer which may be involved in such division or combination, the Company
shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance
with such notice. All Warrants issued on transfers or exchanges shall be dated the initial issuance date of this Warrant and shall
be identical with this Warrant except as to the number of Warrant Shares issuable pursuant thereto.


 


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


 


Section
5. Miscellaneous.


 


a)
No Rights as Stockholder Until Exercise; No Settlement in Cash. This Warrant does not entitle the Holder to any voting
rights, dividends or other rights as a stockholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i),
except as expressly set forth in Section 3. Without limiting any rights of a Holder to receive Warrant Shares on a “cashless
exercise” pursuant to Section 2(c) or to receive cash payments pursuant to Section 2(d)(i) and Section 2(d)(iv) herein,
in no event shall the Company be required to net cash settle an exercise of this Warrant.


 




    	 



     


    

 


b)
Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant
Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, solely in the
case of a Warrant evidenced by a physical Warrant certificate, shall include the posting of a 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, which, in the case of the Warrant, shall
include the posting of a bond.


 


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. This Warrant shall not be exercisable until the Authorized Share Increase Date. In connection with a
meeting of stockholders to obtain the Authorized Share Approval, the Company shall provide each stockholder with a proxy statement
and shall use its reasonable best efforts to solicit its stockholders’ approval of such increase in authorized shares of
Common Stock and to cause its Board of Directors to recommend to the stockholders that they approve such proposal. For the avoidance
of doubt, in the event the Company fails to obtain Authorized Share Approval, in no event shall any cash be payable to the Holder
with respect to this Warrant.


 


The
Company covenants that, from and after the Authorized Share Increase Date, during the period the Warrant is outstanding, it will
reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of the Warrant
Shares upon the exercise of any purchase rights under this Warrant. The Company further covenants that its issuance of this Warrant
shall constitute full authority to its officers who are charged with the duty of issuing the necessary Warrant Shares upon the
exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure
that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements
of the Trading Market upon which the Common Stock may be listed. The Company covenants that all Warrant Shares which may be issued
upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by
this Warrant and payment for such Warrant Shares in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable
and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect
of any transfer occurring contemporaneously with such issue).


 




    	 



     


    

 


Except
and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation,
amending its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution,
issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the
terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all
such actions as may be necessary or appropriate to protect the rights of Holder as set forth in this Warrant against impairment.
Without limiting the generality of the foregoing, the Company will (i) not increase the par value of any Warrant Shares above
the amount payable therefor upon such exercise immediately prior to such increase in par value, (ii) take all such action as may
be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares
upon the exercise of this Warrant and (iii) use commercially reasonable efforts to obtain all such authorizations, exemptions
or consents from any public regulatory body having jurisdiction thereof, as may be, necessary to enable the Company to perform
its obligations under this Warrant.


 


Before
taking any action which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or
in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be
necessary from any public regulatory body or bodies having jurisdiction thereof.


 


For
the avoidance of doubt, in the event that the Company does not obtain the Authorized Share Approval by the Termination Date, this
Warrant will expire unexercisable.


 


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


 




    	 



     


    

 


f)
Restrictions. The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered,
and the Holder does not utilize cashless exercise, will have restrictions upon resale imposed by state and federal securities
laws.


 


g)
Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder
shall operate as a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies. Without limiting
any other provision of this Warrant, if the Company willfully and knowingly fails to comply with any provision of this Warrant,
which results in any material damages to the Holder, the Company shall pay to the Holder such amounts as shall be sufficient to
cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate proceedings,
incurred by the Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies
hereunder.


 


h)
Notices. Any and all notices or other communications or deliveries to be provided by the Holders hereunder including, without
limitation, any Notice of Exercise, shall be in writing and delivered personally, by facsimile or e-mail, or sent by a nationally
recognized overnight courier service, addressed to the Company, at 70 Doppler, Irvine, CA 92618, Attention: Craig Glynn, facsimile
number: 949-261-2992, email address: cglynn@hancockjaffe.com, or such other facsimile number, email address or address as the
Company may specify for such purposes by notice to the Holders. Any and all notices or other communications or deliveries to be
provided by the Company hereunder shall be in writing and delivered personally, by facsimile or e-mail, or sent by a nationally
recognized overnight courier service addressed to each Holder at the facsimile number, e-mail address or address of such Holder
appearing on the books of the Company. Any notice or other communication or deliveries hereunder shall be deemed given and effective
on the earliest of (i) the time of transmission, if such notice or communication is delivered via facsimile at the facsimile number
or via e-mail at the e-mail address set forth in this Section prior to 5:30 p.m. (New York City time) on any date, (ii) the next
Trading Day after the time of transmission, if such notice or communication is delivered via facsimile at the facsimile number
or via e-mail at the e-mail address set forth in this Section on a day that is not a Trading Day or later than 5:30 p.m. (New
York City time) on any Trading Day, (iii) the second Trading Day following the date of mailing, if sent by U.S. nationally recognized
overnight courier service, or (iv) upon actual receipt by the party to whom such notice is required to be given. To the extent
that any notice provided hereunder constitutes, or contains, material, non-public information regarding the Company or any Subsidiaries,
the Company shall simultaneously file such notice with the Commission pursuant to a Current Report on Form 8-K.


 


i)
Limitation of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant
to purchase Warrant Shares, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability
of the Holder for the purchase price of any Common Stock or as a stockholder of the Company, whether such liability is asserted
by the Company or by creditors of the Company.


 




    	 



     


    

 


j)
Remedies. The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages,
will be entitled to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not
be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees
to waive and not to assert the defense in any action for specific performance that a remedy at law would be adequate.


 


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,
on the one hand, and the Holder or the beneficial owner of this Warrant, on the other hand. This Warrant also may be modified
or amended or the provisions hereof waived with the written consent of the Company and the holders of Warrants representing 67%
of the Warrant Shares issuable under Warrants then outstanding as of the date such consent is sought; provided, however, that
(i) no such amendment shall adversely affect any Holder differently than it affects all other Holders, unless such Holder consents
thereto and (ii) no amendment may increase the Exercise Price, decrease the number of shares or change the class of shares obtainable
upon exercise of this Warrant or decrease the time period in which this Warrant can be exercised without the written consent of
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.
