Section 2.          Exercise.


 


a)        Exercise
of Warrant. Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times
on or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company (or such other office or
agency of the Company as it may designate by notice in writing to the registered Holder at the address of the Holder appearing
on the books of the Company) of a duly executed facsimile copy of the Notice of Exercise Form annexed hereto; and, within 3 Business
Days of the date said Notice of Exercise is delivered to the Company, the Company shall have received payment of the aggregate
Exercise Price of the shares thereby purchased by wire transfer or cashier’s check drawn on a United States bank. Notwithstanding
anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company until the
Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case,
the Holder shall surrender this Warrant to the Company for cancellation within 3 Business Days of the date the final Notice of
Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number
of Warrant Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder
in an amount equal to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing
the number of Warrant Shares purchased and the date of such purchases. The Company shall deliver any objection to any Notice of
Exercise Form within 1 Business Day of receipt of such notice. In the event of any dispute or discrepancy, the records of the
Company shall be controlling and determinative in the absence of manifest error. The Holder and any assignee, by acceptance
of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion
of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less than
the amount stated on the face hereof.

(the “Exercise Price”).

(A) = the Market
Price on the Trading Day immediately preceding the date of such election;


 


(B) = the Exercise
Price of this Warrant, as adjusted; and


 


(X) = the
number of Warrant Shares issuable upon exercise of this Warrant in accordance with the terms of this Warrant by means of a cash
exercise rather than a cashless exercise.


 



    	3



    	 



    

 


d)       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 person
or entity acting as a group together with the Holder or any of the Holder’s Affiliates), would beneficially own in excess
of the Beneficial Ownership Limitation (as defined below).  For purposes of the foregoing sentence, the number of shares of
Common Stock beneficially owned by the Holder and its Affiliates shall include the number of shares of Common Stock issuable upon
exercise of this Warrant with respect to which such determination is being made, but shall exclude the number of shares of Common
Stock which would be issuable upon (A) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the
Holder or any of its Affiliates and (B) exercise or conversion of the unexercised or nonconverted portion of any other securities
of the Company (including, without limitation, any other Common Stock Equivalents) subject to a limitation on conversion or exercise
analogous to the limitation contained herein beneficially owned by the Holder or any of its affiliates.  Except as set forth
in the preceding sentence, for purposes of this Section 2(d), 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(d) applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by
the Holder together with any Affiliates) and of which portion of this Warrant is exercisable shall be in the sole discretion of
the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder’s determination of whether this Warrant
is exercisable (in relation to other securities owned by the Holder together with any Affiliates) and of which portion of this
Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Company shall have no obligation to
verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above
shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder.
For purposes of this Section 2(d), 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 (x) the Company’s most recent periodic or annual report, as the case
may be, (y) a more recent public announcement by the Company or (z) any other 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
five Trading Days confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding.  In any
case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of
securities of the Company, including this Warrant, by the Holder or its Affiliates since the date as of which such number of outstanding
shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% of the number of shares
of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon exercise
of this Warrant. The Holder, upon not less than 61 days’ prior notice to the Company, may increase or decrease the Beneficial
Ownership Limitation provisions of this Section 2(d), 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(d) shall continue to apply. Any such increase
or decrease will not be effective until the 61st day after such notice is delivered to the Company. The provisions of
this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section
2(d) 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

e)          Mechanics
of Exercise.


 


i.            Delivery
of Certificates Upon Exercise. Certificates for shares purchased hereunder shall be transmitted by the Transfer Agent to the
Holder by crediting the account of the Holder’s prime broker with the Depository Trust Company through its Deposit Withdrawal
Agent Commission (“DWAC”) system if the Company is a participant in such system and either (A) there is an effective
Registration Statement permitting the resale of the Warrant Shares by the Holder or (B) the shares are eligible for resale without
volume or manner-of-sale limitations pursuant to Rule 144, and otherwise by physical delivery to the address specified by the Holder
in the Notice of Exercise within 3 Trading Days from the delivery to the Company of the Notice of Exercise Form, surrender of this
Warrant (if required) and payment of the aggregate Exercise Price as set forth above (“Warrant Share Delivery Date”).
This Warrant shall be deemed to have been exercised on the date the Exercise Price is received by the Company. The Warrant Shares
shall be deemed to have been issued, and Holder or any other person so designated to be named therein shall be deemed to have become
a holder of record of such shares for all purposes, as of the date the Warrant has been exercised by payment to the Company of
the Exercise Price (or by cashless exercise, if permitted) and all taxes required to be paid by the Holder, if any, pursuant to
Section 2(e)(v) prior to the issuance of such shares, have been paid.


 


ii.         Delivery
of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder
and upon surrender of this Warrant certificate, at the time of delivery of the certificate or certificates representing Warrant
Shares, deliver to Holder a new Warrant evidencing the rights of 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 its the Transfer Agent to transmit to the Holder a certificate or certificates representing
the Warrant Shares pursuant to Section 2(e)(i) by the Warrant Share Delivery Date, then the Holder will have the right to rescind
such exercise.


 



    	5



    	 



    

 


iv.         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 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.


 


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


 


vi.         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.


 


Section 3.             Certain
Adjustments.


 


a)          Stock
Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (A) pays a stock dividend or otherwise
make 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), (B) subdivides outstanding shares of Common Stock into a larger number of shares, (C) combines (including
by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or (D) 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.


 



    	6



    	 



    

 


b)          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.


 


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


 


d)          Notice
to Holder.


 


i.            Adjustment
to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall within
45 calendar days, provide the Holder a notice setting forth the Exercise Price after such adjustment and setting forth a brief
statement of the facts requiring such adjustment. Notwithstanding the forgoing, in the event the Company makes a public disclosure
regarding the adjustment to exercise price, notice will be deemed to have been made pursuant to this section.


 


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, any sale or transfer
of all or substantially all of the assets of the Company, of any compulsory share exchange whereby the Common Stock is converted
into other securities, cash or property; (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation
or winding up of the affairs of the Company; then, in each case, the Company shall cause to be mailed to the Holder at its last
address as it shall appear upon the Warrant Register of the Company, at least 5 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 mail such notice or any defect therein or in the mailing thereof shall
not affect the validity of the corporate action required to be specified in such notice. The Holder is 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.


 



    	7



    	 



    

 


 


Section 4.           Transfer
of Warrant.


 


a)        Transferability.
Upon receipt of such permission, and subject to compliance with any applicable securities laws and the conditions set forth in
Section 4(d) hereof, this Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable,
in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent, together with
a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney
and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required,
such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable,
and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant
evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. The Warrant, if properly
assigned, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.


 


b)       New
Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the
Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by
the Holder or its agent or attorney. Subject to compliance with Section 4(a), as to any transfer which may be involved in such
division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants
to be divided or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall be dated the original
Issue Date and shall be identical with this Warrant except as to the number of Warrant Shares issuable pursuant thereto.


 


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


 



    	8



    	 



    

 


d)        Transfer
Restrictions. If, at the time of
the surrender of this Warrant in connection with any transfer of this Warrant, the transfer of this Warrant shall not be eligible
for resale without volume or manner-of-sale restrictions pursuant to Rule 144, the Company may require, as a condition of allowing
such transfer, that the Holder or transferee of this Warrant, as the case may be, may be required by the Company to provide an
opinion of counsel with regard to such assignment or transfer.


 


Section 5.           Miscellaneous.


 


a)        No Rights
as Shareholder Until Exercise. This Warrant does not entitle the Holder to any voting rights or other rights as a shareholder
of the Company prior to the exercise hereof as set forth in Section 2(e)(i).


 


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


 


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


 


d)      Governing
Law and Venue. 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 Delaware, 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 its respective affiliates, directors,
officers, shareholders, employees or agents) shall be commenced exclusively in the Federal Courts of the State of Delaware. Each
party hereby irrevocably submits to the exclusive jurisdiction of the Federal Courts in the State of Delaware 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 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 or proceeding to enforce any provisions of this Warrant, then the prevailing
party in such action or proceeding shall be reimbursed by the other party for its reasonable attorneys’ fees and other costs
and expenses incurred with the investigation, preparation and prosecution of such action or proceedings or questions concerning
the construction, validity, enforcement and interpretation of this Warrant.


 



    	9



    	 



    

 


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


 


f)         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 Holder’s rights, powers or remedies, notwithstanding the fact that all rights
hereunder terminate on the Termination Date. 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 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 Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies
hereunder.


 


g)        Notices.
Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and
shall be deemed given and effective on the earliest of (a) the date of transmission, if such notice or communication is delivered
via facsimile at the facsimile number set forth on the signature pages attached hereto prior to 5:30 p.m. (New York City time)
on a Trading Day, (b) the next Trading Day after the date of transmission, if such notice or communication is delivered via facsimile
at the facsimile number set forth on the signature pages attached hereto on a day that is not a Trading Day or later than 5:30
p.m. (New York City time) on any Trading Day, (c) the second Trading Day following the date of mailing, if sent by U.S. nationally
recognized overnight courier service, or (d) upon actual receipt by the party to whom such notice is required to be given. The
address for such notices and communications shall be: (i) if to Holder, at its address of records as contained in the Warrant Register,
and (ii) if to Company, at its corporate headquarters.


 


h)        Limitation
of Liability. No provision hereof, in the absence of any affirmative action by Holder to exercise this Warrant to purchase
Warrant Shares, and no enumeration herein of the rights or privileges of Holder, shall give rise to any liability of 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.


 


i)         Remedies.
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.


 



    	10



    	 



    

 


j)         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 of the Company and the successors and permitted assigns of Holder. The provisions
of this Warrant are intended to be for the benefit of all Holders from time to time of this Warrant and shall be enforceable by
the Holder or holder of Warrant Shares.


 


k)        Amendment.
This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and the Holder.


 


l)         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.
