WHEREAS,
the Company is engaged in a public rights offering (the “Offering”) pursuant to which the Company has distributed,

WHEREAS,
the Units consists of shares of Series C Convertible Preferred Stock (the “Preferred Stock”) and warrants (collectively,

transferees, successors and assigns and “Holder” shall include, if the Warrants are held in “street name,”
a Participant (as defined below) or a designee appointed by such Participant) to purchase an aggregate of up to 6,372,000 shares
of Common Stock upon the terms and subject to the conditions hereinafter set forth;


 


WHEREAS,
the Preferred Stock and Warrants to be issued in connection with the Offering shall be immediately separable and will be issued

WHEREAS,
the Company wishes the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing so to act, in connection
with the issuance, registration, transfer, exchange, exercise and replacement of the Warrants and, in the Warrant Agent’s

NOW,
THEREFORE, in consideration of the premises and the mutual agreements herein set forth, the parties hereby agree as follows:

Section
2. Appointment of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the Company in accordance
with the terms and conditions hereof, and the Warrant Agent hereby accepts such appointment. The Company may from time to time
appoint a Co-Warrant Agent as it may, in its sole discretion, deem necessary or desirable. The Warrant Agent shall have no duty
to supervise, and will in no event be liable for the acts or omissions of, any co-Warrant Agent.


 


Section
3. Global Warrants.


 


(a)       The
Warrants shall be initially issuable in book entry form. Unless otherwise instructed by the Company, all of the Warrants shall
initially be represented by one or more book entry form Warrants (the “Global Warrants”) deposited with the
Warrant Agent and registered in the name of Cede & Co., a nominee of The Depository Trust Company (the “Depositary”),
or as otherwise directed by the Depositary. Ownership of beneficial interests in the Warrants shall be shown on, and the transfer
of such ownership shall be effected through, records maintained by (i) the Depositary or its nominee for each Global Warrant or
(ii) institutions that have accounts with the Depositary (such institution, with respect to a Warrant in its account, a “Participant”).


 


(b)       If
the Depositary subsequently ceases to make its book-entry settlement system available for the Warrants, the Company may instruct
the Warrant Agent regarding 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 Warrant Agent shall provide written instructions
to the Depositary to deliver to the Warrant Agent for cancellation each Global Warrant, and the Company shall instruct the Warrant
Agent to deliver to each Holder a Warrant Certificate.


 


(c)       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 (such separate certificate, a “Definitive Certificate”)
evidencing the same number of Warrants, which request shall be in the form attached hereto as Annex A (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 Definitive Certificate for such
number of Warrants in the name set forth in the Warrant Certificate Request Notice. Such Definitive Certificate shall be dated
the original issue date of the Warrants, shall be manually executed by an authorized signatory of the Company and shall be in
the form attached hereto as Exhibit 1. In connection with a Warrant Exchange, the Company agrees to deliver, or to direct
the Warrant Agent to deliver, the Definitive Certificate to the Holder within four (4) 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 Warrant) of the Common Stock on the Warrant Certificate Request Notice Date), $10 per Business Day (increasing
to $20 per Business Day on the fifth Business Day after such liquidated damages begin to accrue) 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 Definitive Certificate and, notwithstanding anything to the
contrary set forth herein, the Definitive 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, other than Section 3(c) and 3(d), which
shall not apply to the Warrants evidenced by a Definitive Certificate. Notwithstanding anything to the contrary contained in this
Agreement, in the event of inconsistency between any provision in this Agreement and any provision in a Definitive Certificate,
as it may from time to time be amended, the terms of such Definitive Certificate shall control.

(d)       A
Holder of a Definitive Certificate (pursuant to a Warrant Exchange or otherwise) has the right to elect at any time or from time
to time a Global Warrants Exchange (as defined below) pursuant to a Global Warrants Request Notice (as defined below). Upon written
notice by a Holder to the Company for the exchange of some or all of such Holder’s Warrants evidenced by a Definitive Certificate
for a beneficial interest in Global Warrants held in book-entry form through the Depositary evidencing the same number of Warrants,
which request shall be in the form attached hereto as Annex B (a “Global Warrants Request Notice” and the date
of delivery of such Global Warrants Request Notice by the Holder, the “Global Warrants Request Notice Date”
and the surrender upon delivery by the Holder of the Warrants evidenced by Definitive Certificates for the same number of Warrants
evidenced by a beneficial interest in Global Warrants held in book-entry form through the Depositary, a “Global Warrants
Exchange”), the Company shall promptly effect the Global Warrants Exchange and shall promptly direct the Warrant Agent
to issue and deliver to the Holder Global Warrants for such number of Warrants in the Global Warrants Request Notice, which beneficial
interest in such Global Warrants shall be delivered by the Depositary’s Deposit or Withdrawal at Custodian system to the
Holder pursuant to the instructions in the Global Warrants Request Notice. In connection with a Global Warrants Exchange, the
Company shall direct the Warrant Agent to deliver the beneficial interest in such Global Warrants to the Holder within ten (10)
Business Days of the Global Warrants Request Notice pursuant to the delivery instructions in the Global Warrant Request Notice
(“Global Warrants Delivery Date”). The Company covenants and agrees that, upon the date of delivery of the
Global Warrants Request Notice, the Holder shall be deemed to be the beneficial holder of such Global Warrants.


 


Section
4. Form of Warrant. The Warrants, together with the form of election to purchase Common Stock (the “Exercise Notice”)
and the form of assignment to be printed on the reverse thereof, whether a Warrant Certificate or a Global Warrant, shall be substantially
in the form of Exhibit 1 hereto.


 


Section
5. Countersignature and Registration. The Warrant Certificates shall be executed on behalf of the Company by its Chief
Executive Officer or Chief Financial Officer, either manually or by facsimile signature, and, if applicable, have affixed thereto
the Company’s seal or a facsimile thereof which shall be attested by the Secretary or an Assistant Secretary of the Company,
either manually or by facsimile signature. The Warrant Certificates shall be countersigned by the Warrant Agent either manually
or by facsimile signature and shall not be valid for any purpose unless so countersigned. In case any officer of the Company who
shall have signed a Warrant shall cease to be such officer of the Company before countersignature by the Warrant Agent and issuance
and delivery by the Company, such Warrant, 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 had not ceased to be such officer of the Company; and any
Warrant may be signed on behalf of the Company by any person who, at the actual date of the execution of such Warrant, shall be
a proper officer of the Company to sign such Warrant, although at the date of the execution of this Warrant Agreement any such
person was not such an officer.


 


The
Warrant Agent will keep or cause to be kept, at one of its offices, or at the office of one of its agents, books for registration
and transfer of the Warrant Certificates issued hereunder. Such books shall show the names and addresses of the respective Holders
of the Warrant Certificates, the number of warrants evidenced on the face of each of such Warrant Certificate and the date of
each of such Warrant Certificate. The Warrant Agent will create a special account for the issuance of Warrant Certificates.


 


Section
6. Transfer, Split Up, Combination and Exchange of Warrant Certificates; Mutilated, Destroyed, Lost or Stolen Warrant Certificates.
Subject to the provisions of the Warrant and the last sentence of this first paragraph of Section 6 and subject to applicable
law, rules or regulations, or any “stop transfer” instructions the Company may give to the Warrant Agent, at any time
after the closing date of the Offering, and at or prior to the Close of Business on the Termination Date, any Warrant Certificate
or Warrant Certificates or Global Warrant or Global Warrants may be transferred, split up, combined or exchanged for another Warrant
Certificate or Warrant Certificates or Global Warrant or Global Warrants, entitling the Holder to purchase a like number of shares
of Common Stock as the Warrant Certificate or Warrant Certificates or Global Warrant or Global Warrants surrendered then entitled
such Holder to purchase. Any Holder desiring to transfer, split up, combine or exchange any Warrant Certificate or Global Warrant
shall make such request in writing delivered to the Warrant Agent, and shall surrender the Warrant Certificate or Warrant Certificates
to be transferred, split up, combined or exchanged at the principal office of the Warrant Agent, provided that no such surrender
is applicable to the Holder of a Global Warrant. Any requested transfer of Warrants, whether a Global Warrant or a Warrant Certificate,
shall be accompanied by reasonable evidence of authority of the party making such request that may be required by the Warrant
Agent. Thereupon the Warrant Agent shall, subject to the last sentence of this first paragraph of Section 6, countersign and deliver
to the Person entitled thereto any Warrant Certificate or Global Warrant, as the case may be, as so requested. The Company may
require payment from the Holder of a sum sufficient to cover any tax or governmental charge that may be imposed in connection
with any transfer, split up, combination or exchange of Warrants. The Company shall compensate the Warrant Agent per the fee schedule
mutually agreed upon by the parties hereto and provided separately on the date hereof.


 


Upon
receipt by the Warrant Agent of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of a Warrant
Certificate, which evidence shall include an affidavit of loss, or in the case of mutilated certificates, the certificate or portion
thereof remaining, and, in case of loss, theft or destruction, of indemnity in customary form and amount, and satisfaction of
any other reasonable requirements established by Section 8-405 of the Uniform Commercial Code as in effect in the State of Delaware,
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 Company will make and deliver a new Warrant Certificate
of like tenor to the Warrant Agent for delivery to the Holder in lieu of the Warrant Certificate so lost, stolen, destroyed or
mutilated.

Section
7. Exercise of Warrants; Exercise Price; Termination Date.


 


(a)       The
Warrants shall be exercisable commencing on the Initial Exercise Date. The Warrants shall cease to be exercisable and shall terminate
and become void, and all rights thereunder and under this Agreement shall cease, at or prior to the Close of Business on the Termination
Date. Subject to the foregoing and to Section 7(b) below, the Holder of a Warrant may exercise the Warrant in whole or in part
upon providing the items required by Section 7(c) below to the Warrant Agent at the principal office of the Warrant Agent or to
the office of one of its agents as may be designated by the Warrant Agent from time to time. In the case of the Holder of a Global
Warrant, the Holder shall deliver the executed Exercise Notice and payment of the Exercise Price pursuant to Section 2(a) of the
Warrant. Notwithstanding any other provision in this Agreement, a holder whose interest in a Global Warrant is a beneficial interest
in a Global Warrant held in book-entry form through the Depositary (or another established clearing corporation performing similar
functions), shall effect exercises by delivering to the Depositary (or such other clearing corporation, as applicable) the appropriate
instruction form for exercise, complying with the procedures to effect exercise that are required by the Depositary (or such other
clearing corporation, as applicable). The Company acknowledges that the bank accounts maintained by the Warrant Agent in connection
with the services provided under this Agreement will be in the Warrant Agent’s name and that the Warrant Agent may receive
investment earnings in connection with the investment at Warrant Agent risk and for its benefit of funds held in those accounts
from time to time. Neither the Company nor the Holders will receive interest on any deposits or Exercise Price.


 


(b)       Upon
receipt of an Exercise Notice for a cashless exercise pursuant to Section 2(c) of the Warrant (each, a “Cashless Exercise”),
the Company will promptly calculate and transmit to the Warrant Agent the number of Warrant Shares issuable in connection with
such Cashless Exercise and deliver a copy of the Exercise Notice to the Warrant Agent, which shall issue such number of Warrant
Shares in connection with such Cashless Exercise.


 


(c)       Upon
the Warrant Agent’s receipt, at or prior to the Close of Business on the Termination Date set forth in a Warrant, of the
executed Exercise Notice, accompanied by payment of the Exercise Price pursuant to Section 2(a) of the Warrant for the shares
to be purchased (other than in the case of a Cashless Exercise), an amount equal to any applicable tax, governmental charge or
expense reimbursement referred to in Section 6 in cash, or by certified check or bank draft payable to the order of the Company
and, in the case of an exercise of a Warrant in the form of a Warrant Certificate for all of the Warrant Shares represented thereby,
the Warrant Certificate, the Warrant Agent shall cause the Warrant Shares underlying such Warrant to be delivered to or upon the
order of the Holder of such Warrant, registered in such name or names as may be designated by such Holder, no later than the date
that is two (2) Trading Days after the date of delivery of the Exercise Notice (the “Warrant Share Delivery Date”).
If the Company is then a participant in the DWAC system of the Depositary 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) the Warrant is being exercised
via Cashless Exercise, then the certificates for Warrant Shares shall be transmitted by the Warrant Agent to the Holder by crediting
the account of the Holder’s broker with the Depositary through its DWAC system. For the avoidance of doubt, if the Company
becomes obligated to pay any amounts to any Holders pursuant to Section 2(d)(i) or 2(d)(iv) of the Warrant, such obligation shall
be solely that of the Company and not that of the Warrant Agent. Notwithstanding anything else to the contrary in this Agreement,
except in the case of a Cashless Exercise, if any Holder fails to duly deliver payment to the Warrant Agent of an amount equal
to the aggregate Exercise Price of the Warrant Shares to be purchased upon exercise of such Holder’s Warrant as set forth
in Section 7(a) hereof, the Warrant Agent will not be obligated to deliver certificates representing any such Warrant Shares (via
DWAC or otherwise) until following receipt of such payment, and the applicable Warrant Share Delivery Date shall be deemed extended
by one day for each day (or part thereof) until such payment is delivered to the Warrant Agent.


 


(d)       The
Warrant Agent shall deposit all funds received by it in payment of the Exercise Price for all Warrants in the account of the Company
maintained with the Warrant Agent for such purpose (or to such other account as directed by the Company in writing) and shall
advise the Company via telephone at the end of each day on which funds for the exercise of any Warrant are received of the amount
so deposited to its account. The Warrant Agent shall promptly confirm such telephonic advice to the Company in writing.


 


(e)       In
case the Holder of any Warrant Certificate exercises fewer than all Warrants evidenced thereby and surrenders such Warrant Certificate
in connection with such partial exercise, a new Warrant Certificate evidencing the number of Warrant Shares equivalent to the
number of Warrant Shares remaining unexercised may be issued by the Warrant Agent to the Holder of such Warrant Certificate or
to his duly authorized assigns in accordance with Section 2(d)(ii) of the Warrant, subject to the provisions of Section 6 hereof.


 






    	5



    	 



    

 


Section
8. Cancellation and Destruction of Warrant Certificates. All Warrant Certificates surrendered for the purpose of exercise,
transfer, split up, combination or exchange shall, if surrendered to the Company or to any of its agents, be delivered to the
Warrant Agent for cancellation or in canceled form, or, if surrendered to the Warrant Agent, shall be canceled by it, and no Warrant
Certificates shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Agreement. The Company
shall deliver to the Warrant Agent for cancellation and retirement, and the Warrant Agent shall so cancel and retire, any other
Warrant Certificate purchased or acquired by the Company otherwise than upon the exercise thereof. The Warrant Agent shall deliver
all canceled Warrant Certificates to the Company, or shall, at the written request of the Company, destroy such canceled Warrant
Certificates, and in such case shall deliver a certificate of destruction thereof to the Company, subject to any applicable law,
rule or regulation requiring the Warrant Agent to retain such canceled certificates.


 


Section
9. Certain Representations; Reservation and Availability of Shares of Common Stock or Cash.


 


(a)       This
Agreement has been duly authorized, executed and delivered by the Company and, assuming due authorization, execution and delivery
hereof by the Warrant Agent, constitutes a valid and legally binding obligation of the Company enforceable against the Company
in accordance with its terms, and the Warrants have been duly authorized, executed and issued by the Company and, assuming due
authentication thereof by the Warrant Agent pursuant hereto and payment therefor by the Holders as provided in the Registration
Statement, constitute valid and legally binding obligations of the Company enforceable against the Company in accordance with
their terms and entitled to the benefits thereof; in each case except as enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally or by general equitable
principles (regardless of whether such enforceability is considered in a proceeding in equity or at law).


 


(b)       As
of the date hereof and prior to the Offering, the authorized capital stock of the Company consists of (i) 250,000,000 shares
of Common Stock, of which 2,434,008 shares of Common Stock are issued and outstanding, and (ii) 130,000,000 shares
of undesignated preferred stock, par value $0.01 per share, none of which are designated Series A Convertible Preferred
Stock, 0 of which are issued and outstanding, and 15,000 of which are designated Series B Preferred Stock, 249
of which are issued and outstanding. 390,883 shares of Common Stock are reserved for issuance upon exercise of the
Warrants. Except as disclosed in the Registration Statement, there are no other outstanding obligations, warrants, options or
other rights to subscribe for or purchase from the Company any class of capital stock of the Company.


 


(c)       The
Company covenants and agrees that it will cause to be reserved and kept available out of its authorized and unissued shares of
Common Stock or its authorized and issued shares of Common Stock held in its treasury, free from preemptive rights, the number
of shares of Common Stock that will be sufficient to permit the exercise in full of all outstanding Warrants.


 


(d)       The
Warrant Agent will create a special account for the issuance of Common Stock upon the exercise of Warrants.


 


(e)       The
Company further covenants and agrees that it will pay when due and payable any and all federal and state transfer taxes and charges
which may be payable in respect of the original issuance or delivery of the Warrant Certificates or certificates evidencing Common
Stock upon exercise of the Warrants. The Company shall not, however, be required to pay any tax or governmental charge which may
be payable in respect of any transfer involved in the transfer or delivery of Warrant Certificates or the issuance or delivery
of certificates for Common Stock in a name other than that of the Holder of the Warrant Certificate evidencing Warrants surrendered
for exercise or to issue or deliver any certificate for shares of Common Stock upon the exercise of any Warrants until any such
tax or governmental charge shall have been paid (any such tax or governmental charge being payable by the Holder of such Warrant
Certificate at the time of surrender) or until it has been established to the Company’s reasonable satisfaction that no
such tax or governmental charge is due.


 


Section
10. Common Stock Record Date. Each Holder shall be deemed to have become the holder of record for the Warrant Shares pursuant
to Section 2(d)(i) of the Warrants.


 


Section
11. Adjustment of Exercise Price, Number of Shares of Common Stock or Number of the Company Warrants. The Exercise Price,
the number of shares covered by each Warrant and the number of Warrants outstanding are subject to adjustment from time to time
as provided in Section 3 of the Warrant. In the event that at any time, as a result of an adjustment made pursuant to Section
3 of the Warrant, the Holder of any Warrant thereafter exercised shall become entitled to receive any shares of capital stock
of the Company other than shares of Common Stock, thereafter the number of such other shares so receivable upon exercise of any
Warrant shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions
with respect to the shares contained in Section 3 of the Warrant, and the provisions of Sections 7, 9 and 13 of this Agreement
with respect to the shares of Common Stock shall apply on like terms to any such other shares. All Warrants originally issued
by the Company subsequent to any adjustment made to the Exercise Price pursuant to the Warrant shall evidence the right to purchase,
at the adjusted Exercise Price, the number of shares of Common Stock purchasable from time to time hereunder upon exercise of
the Warrants, all subject to further adjustment as provided herein.


 






    	6



    	 



    

 


Section
12. Certification of Adjusted Exercise Price or Number of Shares of Common Stock. Whenever the Exercise Price or the number
of shares of Common Stock issuable upon the exercise of each Warrant is adjusted as provided in Section 11 or 13, the Company
shall (a) promptly prepare a certificate setting forth the Exercise Price of each Warrant as so adjusted, and a brief statement
of the facts accounting for such adjustment, (b) promptly file with the Warrant Agent and with each transfer agent for the Common
Stock a copy of such certificate and (c) instruct the Warrant Agent to send a brief summary thereof to each Holder of a Warrant.


 


Section
13. Fractional Shares of Common Stock.


 


(a)       The
Company shall not issue fractions of Warrants or distribute a Global Warrant or Warrant Certificates that evidence fractional
Warrants. Whenever any fractional Warrant would otherwise be required to be issued or distributed, the actual issuance or distribution
shall reflect a rounding of such fraction either up or down to the nearest whole Warrant.


 


(b)       The
Company shall not issue fractions of shares of Common Stock upon exercise of Warrants or distribute stock certificates that evidence
fractional shares of Common Stock. Whenever any fraction of a share of Common Stock would otherwise be required to be issued or
distributed, the actual issuance or distribution in respect thereof shall be made in accordance with Section 2(d)(v) of the Warrant.


 


Section
14. Conditions of the Warrant Agent’s Obligations. The Warrant Agent accepts its obligations herein set forth upon
the terms and conditions hereof, including the following to all of which the Company agrees and to all of which the rights hereunder
of the Holders from time to time of the Warrant shall be subject:


 


(a)       Compensation
and Indemnification. The Company agrees promptly to pay the Warrant Agent the compensation detailed on Exhibit 2 hereto for all
services rendered by the Warrant Agent and to reimburse the Warrant Agent for reasonable out-of-pocket expenses (including reasonable
counsel fees) incurred without gross negligence, bad faith or willful misconduct by the Warrant Agent in connection with the services
rendered hereunder by the Warrant Agent. The Company also agrees to indemnify the Warrant Agent for, and to hold it harmless against,
any loss, liability or expense incurred without gross negligence, bad faith or willful misconduct on the part of the Warrant Agent,
arising out of or in connection with its acting as Warrant Agent hereunder, including the reasonable costs and expenses of defending
against any claim of such liability.


 


(b)       Agent
for the Company. In acting under this Warrant Agreement and in connection with the Warrant Certificates, the Warrant Agent is
acting solely as agent of the Company and does not assume any obligations or relationship of agency or trust for or with any of
the Holders of Warrant Certificates or beneficial owners of Warrants.


 


(c)       Counsel.
The Warrant Agent may consult with counsel satisfactory to it, which may include counsel for the Company, and the written 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.


 


(d)       Documents.
The Warrant Agent shall be protected and shall incur no liability for or in respect of any action taken or omitted by it in reliance
upon any Warrant Certificate, notice, direction, consent, certificate, affidavit, statement or other paper or document reasonably
believed by it to be genuine and to have been presented or signed by the proper parties.


 


(e)       Certain
Transactions. The Warrant Agent, and its officers, directors and employees, may become the owner of, or acquire any interest in,
Warrants, with the same rights that it or they would have if it were not the Warrant Agent hereunder, and, to the extent permitted
by applicable law, it or they may engage or be interested in any financial or other transaction with the Company and may act on,
or as depositary, trustee or agent for, any committee or body of Holders of Warrant Securities or other obligations of the Company
as freely as if it were not the Warrant Agent hereunder. Nothing in this Warrant Agreement shall be deemed to prevent the Warrant
Agent from acting as trustee under any indenture to which the Company is a party.


 






    	7



    	 



    

 


(f)       No
Liability for Interest. Unless otherwise agreed with the Company, the Warrant Agent shall have no liability for interest on any
monies at any time received by it pursuant to any of the provisions of this Agreement or of the Warrant Certificates.


 


(g)       No
Liability for Invalidity. The Warrant Agent shall have no liability with respect to any invalidity of this Agreement or any of
the Warrant Certificates (except as to the Warrant Agent’s countersignature thereon).


 


(h)       No
Responsibility for Representations. The Warrant Agent shall not be responsible for any of the recitals or representations herein
or in the Warrant Certificates (except as to the Warrant Agent’s countersignature thereon), all of which are made solely
by the Company.


 


(i)       No
Implied Obligations. The Warrant Agent shall be obligated to perform only such duties as are herein and in the Warrants specifically
set forth and no implied duties or obligations shall be read into this Agreement or the Warrants against the Warrant Agent. The
Warrant Agent shall not be under any obligation to take any action hereunder which may tend to involve it in any expense or liability,
the payment of which within a reasonable time is not, in its reasonable opinion, assured to it. The Warrant Agent shall not be
accountable or under any duty or responsibility for the use by the Company of any of the Warrants authenticated by the Warrant
Agent and delivered by it to the Company pursuant to this Agreement or for the application by the Company of the proceeds of the
Warrants. The Warrant Agent shall have no duty or responsibility in case of any default by the Company in the performance of its
covenants or agreements contained herein or in the Warrants or in the case of the receipt of any written demand from a Holder
of a Warrant Certificate with respect to such default, including, without limiting the generality of the foregoing, any duty or
responsibility to initiate or attempt to initiate any proceedings at law.


 


Section
15. Purchase or Consolidation or Change of Name of Warrant Agent. Any corporation into which the Warrant Agent or any successor
Warrant Agent may be merged or with which it may be consolidated, or any corporation resulting from any merger or consolidation
to which the Warrant Agent or any successor Warrant Agent shall be party, or any corporation succeeding to the corporate trust
business of the Warrant Agent or any successor Warrant Agent, shall be the successor to the Warrant Agent under this Agreement
without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that such corporation
would be eligible for appointment as a successor Warrant Agent under the provisions of Section 17. In case at the time such successor
Warrant Agent shall succeed to the agency created by this Agreement any of the Warrants shall have been countersigned but not
delivered, any such successor Warrant Agent may adopt the countersignature of the predecessor Warrant Agent and deliver such Warrants
so countersigned; and in case at that time any of the Warrants shall not have been countersigned, any successor Warrant Agent
may countersign such Warrants either in the name of the predecessor Warrant Agent or in the name of the successor Warrant Agent;
and in all such cases such Warrants shall have the full force provided in the Warrants and in this Agreement.


 


In
case at any time the name of the Warrant Agent shall be changed and at such time any of the Warrants shall have been countersigned
but not delivered, the Warrant Agent may adopt the countersignature under its prior name and deliver Warrants so countersigned;

Section
16. Duties of Warrant Agent. The Warrant Agent undertakes the duties and obligations imposed by this Agreement upon the
following terms and conditions, by all of which the Company, by its acceptance hereof, shall be bound:


 


(a)       The
Warrant Agent may consult with legal counsel reasonably acceptable to the Company (who may be legal counsel for the Company),
and the opinion of such counsel shall be full and complete authorization and protection to the Warrant Agent as to any action
taken or omitted by it in good faith and in accordance with such opinion.


 


(b)       Whenever
in the performance of its duties under this Agreement the Warrant Agent shall deem it necessary or desirable that any fact or
matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless
other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by
a certificate signed by the Chief Executive Officer or Chief Financial Officer of the Company; and such certificate shall be full
authentication to the Warrant Agent for any action taken or suffered in good faith by it under the provisions of this Agreement
in reliance upon such certificate.

(c)       Subject
to the limitation set forth in Section 14, the Warrant Agent shall be liable hereunder only for its own gross negligence, bad
faith or willful misconduct, or for a breach by it of this Agreement.


 


(d)       The
Warrant Agent shall not be liable for or by reason of any of the statements of fact or recitals contained in this Agreement or
in the Warrants (except its countersignature thereof) by the Company or be required to verify the same, but all such statements
and recitals are and shall be deemed to have been made by the Company only.


 


(e)       The
Warrant Agent shall not be under any responsibility in respect of the validity of this Agreement or the execution and delivery
hereof (except the due execution hereof by the Warrant Agent) or in respect of the validity or execution of any Warrant (except
its countersignature thereof); nor shall it be responsible for any breach by the Company of any covenant or condition contained
in this Agreement or in any Warrant; nor shall it be responsible for the adjustment of the Exercise Price or the making of any
change in the number of shares of Common Stock required under the provisions of Section 11 or 13 or responsible for the manner,
method or amount of any such change or the ascertaining of the existence of facts that would require any such adjustment or change
(except with respect to the exercise of Warrants evidenced by Warrant Certificates after actual notice of any adjustment of the
Exercise Price); nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or
reservation of any shares of Common Stock to be issued pursuant to this Agreement or any Warrant or as to whether any shares of
Common Stock will, when issued, be duly authorized, validly issued, fully paid and nonassessable.


 


(f)       Each
party hereto agrees that it will perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and
delivered all such further and other acts, instruments and assurances as may reasonably be required by the other party hereto
for the carrying out or performing by any party of the provisions of this Agreement.


 


(g)       The
Warrant Agent is hereby authorized to accept instructions with respect to the performance of its duties hereunder from the Chief
Executive Officer or Chief Financial Officer of the Company, and to apply to such officers for advice or instructions in connection
with its duties, and it shall not be liable and shall be indemnified and held harmless for any action taken or suffered to be
taken by it in good faith in accordance with instructions of any such officer, provided Warrant Agent carries out such instructions
without gross negligence, bad faith or willful misconduct.


 


(h)       The
Warrant Agent and any shareholder, director, officer or employee of the Warrant Agent may buy, sell or deal in any of the Warrants
or other securities of the Company or become pecuniarily interested in any transaction in which the Company may be interested,
or contract with or lend money to the Company or otherwise act as fully and freely as though it were not Warrant Agent under this
Agreement. Nothing herein shall preclude the Warrant Agent from acting in any other capacity for the Company or for any other
legal entity.


 


(i)       The
Warrant Agent may execute and exercise any of the rights or powers hereby vested in it or perform any duty hereunder either itself
or by or through its attorney or agents, and the Warrant Agent shall not be answerable or accountable for any act, default, neglect
or misconduct of any such attorney or agents or for any loss to the Company resulting from any such act, default, neglect or misconduct,
provided reasonable care was exercised in the selection and continued employment thereof.


 


Section
17. Change of Warrant Agent. The Warrant Agent may resign and be discharged from its duties under this Agreement upon 30
days’ notice in writing sent to the Company and to each transfer agent of the Common Stock, and to the Holders of the Warrant
Certificates. The Company may remove the Warrant Agent or any successor Warrant Agent upon 30 days’ notice in writing, sent
to the Warrant Agent or successor Warrant Agent, as the case may be, and to each transfer agent of the Common Stock, and to the
Holders of the Warrant Certificates. If the Warrant Agent shall resign or be removed or shall otherwise become incapable of acting,
the Company shall appoint a successor to the Warrant Agent. If the Company shall fail to make such appointment within a period
of 30 days after such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated
Warrant Agent or by the Holder of a Warrant Certificate (who shall, with such notice, submit his Warrant Certificate for inspection
by the Company), then the Holder of any Warrant Certificate may apply to any court of competent jurisdiction for the appointment
of a new Warrant Agent. Any successor Warrant Agent, whether appointed by the Company or by such a court, shall be a corporation
organized and doing business under the laws of the United States or of a state thereof, in good standing, which is authorized
under such laws to exercise corporate trust powers and is subject to supervision or examination by federal or state authority
and which has at the time of its appointment as Warrant Agent a combined capital and surplus of at least $50,000,000. After appointment,
the successor Warrant Agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally
named as Warrant Agent without further act or deed; but the predecessor Warrant Agent shall deliver and transfer to the successor
Warrant Agent any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or
deed necessary for the purpose. Not later than the effective date of any such appointment, the Company shall file notice thereof
in writing with the predecessor Warrant Agent and each transfer agent of the Common Stock, and mail a notice thereof in writing
to the Holders of the Warrant Certificates. However, failure to give any notice provided for in this Section 17, or any defect
therein, shall not affect the legality or validity of the resignation or removal of the Warrant Agent or the appointment of the
successor Warrant Agent, as the case may be.

                                         Warrant Shares that would be issuable upon exercise of the Warrants if such exercise
                                         were by means of a cash exercise and (ii) 0.70.



 


		ii.	Additionally,
                                         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 also be exercised, in whole or in part, at
                                         such time by means of a “cashless exercise” in which the Holder shall be
                                         entitled to receive a number of Warrant Shares equal to the quotient obtained by dividing
                                         [(A-B) (X)] by (A), where:

	 	(A)
    =	as applicable: (i) the VWAP on the
    Trading Day immediately preceding the date of the applicable Notice of Exercise if such Notice of Exercise is (1) both executed
    and delivered pursuant to Section 2(a) hereof on a day that is not a Trading Day or (2) both executed and delivered pursuant
    to Section 2(a) hereof on a Trading Day prior to the opening of “regular trading hours” (as defined in Rule 600(b)(64)
    of Regulation NMS promulgated under the federal securities laws) on such Trading Day, (ii) 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.




 


		iii.	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).



 


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

d)       Mechanics
of Exercise.


 


		i.	Delivery
                                         of Warrant Shares Upon Exercise. The Company shall cause the Warrant Shares purchased
                                         hereunder to be transmitted by the Transfer Agent to the Holder by crediting the account
                                         of the Holder’s or its designee’s balance account with The Depository Trust
                                         Company through its Deposit or Withdrawal at Custodian system (“DWAC”)
                                         if the Company is then a participant in such system and either (A) there is an effective
                                         registration statement permitting the issuance of the Warrant Shares to or resale of
                                         the Warrant Shares by 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 by the Holder of the Notice of Exercise,
                                         (ii) one (1) Trading Day after delivery of the aggregate Exercise Price to the Company
                                         and (iii) the number of Trading Days comprising the Standard Settlement Period after
                                         the delivery to the Company of the Notice of Exercise (such date, the “Warrant
                                         Share Delivery Date”). Upon delivery of the Notice of Exercise, the Holder
                                         shall be deemed for all corporate purposes to have become the holder of record of the
                                         Warrant Shares with respect to which this Warrant has been exercised, irrespective of
                                         the date of delivery of the Warrant Shares, provided that payment of the aggregate Exercise
                                         Price (other than in the case of a cashless exercise) is received within the earlier
                                         of (i) two (2) Trading Days and (ii) the number of Trading Days comprising the Standard
                                         Settlement Period following delivery of the Notice of Exercise. If the Company fails
                                         for any reason to deliver to the Holder the Warrant Shares subject to a Notice of Exercise
                                         by the Warrant Share Delivery Date, the Company shall pay to the Holder, in cash, as
                                         liquidated damages and not as a penalty, for each $1,000 of Warrant Shares subject to
                                         such exercise (based on the VWAP of the Common Stock on the date of the applicable Notice
                                         of Exercise), $10 per Trading Day (increasing to $20 per Trading Day on the fifth Trading
                                         Day after such liquidated damages begin to accrue) for each Trading Day after such Warrant
                                         Share Delivery Date until such Warrant Shares are delivered or Holder rescinds such exercise.
                                         The Company agrees to maintain a transfer agent that is a participant in the FAST program
                                         so long as this Warrant remains outstanding and exercisable. As used herein, “Standard
                                         Settlement Period” means the standard settlement period, expressed in a number
                                         of Trading Days, on the Company’s primary Trading Market with respect to the Common
                                         Stock as in effect on the date of delivery of the Notice of Exercise.

ii.       Delivery
of New Warrants Upon Exercise. If this Warrant is not held in global form through DTC (or any successor depositary) and 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.


 






    	10



    	 



    

 


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.


 




    	11



    	 



    

 


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


 


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


 


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

f)       Right
of Redemption. Subject to the provisions of Section 2(e) and this Section 2(f), if, at any time at least one (1) year after
the Initial Exercise Date, (i) the VWAP for each of 10 consecutive Trading Days (the “Measurement Period”),
which 10 consecutive Trading Day period shall not have commenced until one (1) year after the Initial Exercise Date) exceeds $8.00
(subject to adjustment for forward and reverse stock splits, recapitalizations, stock dividends and the like after the Initial
Exercise Date) and (ii) the Holder is not in possession of any information that constitutes, or might constitute, material non-public
information which was provided by the Company, any of its Subsidiaries, or any of their officers, directors, employees, agents
or Affiliates, then the Company may, at its sole option and in its sole discretion, redeem not less than all of the outstanding
Warrants for which a Notice of Exercise has not yet been delivered (such right, a “Redemption Right”) for consideration
equal to $0.01 per Warrant (subject to adjustment for forward and reverse stock splits, recapitalizations, stock dividends and
the like after the Initial Exercise Date, the “Redemption Price”). For the avoidance of any doubt, to the extent
that the Company determines to exercise its Redemption Right pursuant to this Section 2(f), the Company shall be required to exercise
its Redemption Right with respect to all of the other Warrants issued by the Company pursuant to the Registration Statement. To
exercise the Redemption Right, the Company must deliver to all of the Holders an irrevocable written notice (a “Redemption
Notice”) indicating therein the Company’s election to redeem all of the Warrants and setting forth a date for
the redemption of such Warrants, which date shall be at least thirty (30) days after the date of the Redemption Notice (the “Redemption
Date”). The Redemption Notice shall be mailed by first class mail, postage prepaid, by the Company to the Holders of
the Warrants at their last addresses as they shall appear on the Warrant Register. Any Redemption Notice mailed in the manner
herein provided shall be conclusively presumed to have been duly given on the date sent whether or not the Holder received such
notice. The Warrants may be exercised in accordance with the terms herein at any time after the Redemption Notice shall have been
given by the Company pursuant to this Section 2(f) hereof and prior to the Redemption Date. In furtherance thereof, the Company
covenants and agrees that it will honor all Notices of Exercise with respect to Warrant Shares subject to a Redemption Notice
that are tendered through 6:30 p.m. (New York City time) on the Redemption Date. Following the Redemption Date, the Holders of
the Warrants shall have no further rights except to receive the Redemption Price upon surrender of the Warrants. Notwithstanding
anything to the contrary set forth in this Warrant, the Company may not deliver a Redemption Notice or require the redemption
of this Warrant (and any such Redemption Notice shall be void), unless, from the beginning of the Measurement Period through the
Redemption Date, (1) the Company shall have honored in accordance with the terms of this Warrant all Notices of Exercise delivered
by 6:30 p.m. (New York City time) on the Redemption Date, (2) a registration statement shall be effective as to all Warrant Shares
and the prospectus and all relevant amendments and supplements thereunder available for use by the Company for the sale of all
such Warrant Shares to the Holder, (3) the Common Stock shall be listed or quoted for trading on the Trading Market, (4) there
is a sufficient number of authorized shares of Common Stock for issuance of all Warrant Shares, and (5) the issuance of all Warrant
Shares subject to a Redemption Notice shall not cause a breach of any provision of Section 2(e) herein.


 


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.


 




    	13



    	 



    

 


b)       Intentionally
omitted.


 


c)       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, 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).


 


d)       Pro
Rata Distributions. During such time as this Warrant is outstanding, if the Company shall declare or make any dividend or
other distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital
or otherwise (including, without limitation, any distribution of 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).
To the extent that this Warrant has not been partially or completely exercised at the time of such Distribution, such portion
of the Distribution shall be held in abeyance for the benefit of the Holder until the Holder has exercised this Warrant.


 






    	14



    	 



    

 


e)       Fundamental
Transaction. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in one or more related
transactions effects any merger or consolidation of the Company with or into another Person (other than a transaction solely to
change the domicile of the Company), (ii) the Company, directly or indirectly, effects any sale, lease, license, assignment, transfer,
conveyance or other disposition of all or substantially all of its assets in one or a series of related transactions, (iii) any,
direct or indirect, purchase offer, tender offer or exchange offer (whether by the Company or another Person) is completed pursuant
to which holders of Common Stock are permitted to sell, tender or exchange their shares for other securities, cash or property
and has been accepted by the holders of 50% or more of the outstanding Common Stock, (iv) the Company, directly or indirectly,
in one or more related transactions effects any reclassification, reorganization or recapitalization of the Common Stock or any
compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities,
cash or property, or (v) the Company, directly or indirectly, in one or more related transactions consummates a stock or share
purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off,
merger or scheme of arrangement) with another Person or group of Persons whereby such other Person or group acquires more than
50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person or other Persons
making or party to, or associated or affiliated with the other Persons making or party to, such stock or share purchase agreement
or other business combination) (each a “Fundamental Transaction”), then, upon any subsequent exercise of this
Warrant, the Holder shall have the right to receive, for each Warrant Share that would have been issuable upon such exercise immediately
prior to the occurrence of such Fundamental Transaction, at the option of the Holder (without regard to any limitation in Section
2(e) on the exercise of this Warrant), the number of shares of Common Stock of the successor or acquiring corporation or of the
Company, if it is the surviving corporation, and any additional consideration (the “Alternate Consideration”)
receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Warrant
is exercisable immediately prior to such Fundamental Transaction (without regard to any limitation in Section 2(e) on the exercise
of this Warrant). For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to
apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common
Stock in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in
a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common
Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder
shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such
Fundamental Transaction. Notwithstanding anything to the contrary, in the event of a Fundamental Transaction, the Company or any
Successor Entity (as defined below) shall, at the Holder’s option, exercisable at any time concurrently with, or within
30 days after, the consummation of the Fundamental Transaction (or, if later, the date of the public announcement of the applicable
Fundamental Transaction), purchase this Warrant from the Holder by paying to the Holder an amount of cash equal to the Black Scholes
Value (as defined below) of the remaining unexercised portion of this Warrant on the date of the consummation of such Fundamental
Transaction; provided, however, that, 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 greater of 100% and 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 five Business Days of the Holder’s election (or, if later, on the effective date 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(e) pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by
the Holder (without unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the Holder, deliver
to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially
similar in form and substance to this Warrant which is exercisable for a corresponding number of shares of capital stock of such
Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon exercise of this
Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an
exercise price which applies the exercise price hereunder to such shares of capital stock (but taking into account the relative
value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such
number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant
immediately prior to the consummation of such Fundamental Transaction), and which is reasonably satisfactory in form and substance
to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted
for (so that from and after the date of such Fundamental Transaction, the provisions of this Warrant referring to the “Company”
shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the
obligations of the Company under this Warrant with the same effect as if such Successor Entity had been named as the Company herein.

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


 


g)       Notice
to Holder.


 


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


 


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 is a party (other than a transaction
solely to change the domicile of the Company), 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.


 






    	17



    	 



    

 


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 Warrant Agent shall register this Warrant, upon records to be maintained by the Warrant Agent for that purpose
(the “Warrant Register”), in the name of the record Holder hereof from time to time. The Company and the Warrant
Agent 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. This Warrant does not entitle the Holder to any voting rights, dividends or other rights
as a stockholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly set forth in
Section 3.


 


b)       Loss,
Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant
Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case
of the Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate,
if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation,
in lieu of such Warrant or stock certificate.


 


c)       Saturdays,
Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required
or granted herein shall not be a Business Day, then, such action may be taken or such right may be exercised on the next succeeding
Business Day.


 




    	18



    	 



    

 


d)       Authorized
Shares.


 


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


 


Except
and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation,
amending its 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.


 


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


 




    	19



    	 



    

 


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 1885 West 2100 South, Salt Lake City, Utah 84119, , Attention: Chief Executive
Officer, facsimile number: 855.839.3500, email address: sbal@sintx.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 date 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 date 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.


 






    	20



    	 



    

 


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.


 


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.


 


o)       Warrant
Agency Agreement. If this Warrant is held in global form through DTC (or any successor depositary), this Warrant is issued
subject to the Warrant Agency Agreement. To the extent any provision of this Warrant conflicts with the express provisions of
the Warrant Agency Agreement, the provisions of this Warrant shall govern and be controlling.
