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 (or e-mail attachment) of the Notice of Exercise
in the form annexed hereto and within three (3) Trading 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. No ink-original Notice of Exercise shall be required, nor shall any medallion guarantee (or
other type of guarantee or notarization) of any Notice of Exercise form be required. Notwithstanding anything herein to the contrary,
the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased all of the
Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender this
Warrant to the Company for cancellation within three (3) Trading Days of the date the final Notice of Exercise is delivered to
the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares available
hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal
to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing the number of
Warrant Shares purchased and the date of such purchases. The Company shall deliver any objection to any Notice of Exercise within
one (1) Business Day of receipt of such notice. The Holder and any assignee, by acceptance of this Warrant, acknowledge and
agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder,
the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on the face
hereof.


 


b) 
Exercise Price. The exercise price per share of the Common Stock under this Warrant shall be $0.135 (the “Exercise
Price”).

c)
[Reserved]


 


d)
Mechanics of Exercise.


 


i.
Delivery of Warrant Shares Upon Exercise. Within the later of (x) one (1) Business Day of receiving a Notice of Exercise
if a cashless exercise or (y) one (1) Business Day of receipt of payment if exercised for cash, the Company shall have provided
instructions to the Transfer Agent for the issuance of the Warrant Shares. Warrant Shares purchased hereunder shall be transmitted
by the Transfer Agent to the Holder by crediting the account of the Holder’s prime broker 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 the Holder or (B) the Warrant Shares are eligible for resale by the
Holder pursuant to Rule 144, 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 two (2) Trading Days after the later of (A)
the delivery to the Company of the Notice of Exercise and (B) payment of the aggregate Exercise Price as set forth above (unless
by cashless exercise, if permitted) (such date, the “Warrant Share Delivery Date”). The Warrant Shares shall
be deemed to have been issued, and Holder or any other person so designated to be named therein shall be deemed to have become
a holder of record of such shares for all purposes, as of the date the Warrant has been exercised, with payment to the Company
of the Exercise Price (or by cashless exercise, if permitted) and all taxes required to be paid by the Holder, if any, pursuant
to Section 2(d)(vi) prior to the issuance of such shares, having been paid. If the Company fails for any reason to deliver to
the Holder 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. Provided; however, that such liquidated
damages shall only accrue for a maximum of ninety (90) Trading Days.


 


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


 


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


 




    	3



    	 



    




 


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


 


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


 


vi.
Charges, Taxes and Expenses. Issuance of Warrant Shares shall be made without charge to the Holder for any issue or transfer
tax or other incidental expense in respect of the issuance of 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.


 




    	4



    	 



    




 


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.


 


viii.
Disputes. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the number
of Warrant Shares to be issued pursuant to the terms hereof, the Company shall promptly issue to the Holder the number of Warrant
Shares that are not disputed and resolve such dispute in accordance with Section 5(p).


 


e)
[Reserved].


 


f)
Holder’s Exercise Limitations. Except as provided for herein, 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), 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 (i) exercise of the remaining, nonexercised portion
of this Warrant beneficially owned by the Holder or any of its Affiliates and (ii) exercise or conversion of the unexercised or
nonconverted portion of any other securities of the Company (including, without limitation, any other Common Stock 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(F), beneficial ownership
shall be calculated in accordance with Section 13(d) of the 1934 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 1934 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(f) 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 1934 Act and the rules and regulations
promulgated thereunder. For purposes of this Section 2(f), 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 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(f), but
not in excess of 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. 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(f) 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. The provisions of this Section 2(f) shall be of no further force or effect
if the Holder participates in a subsequent transaction with the Company which results in the Holder beneficially owning in excess
of 4.99% of the number of shares of the Common Stock outstanding which shall include securities convertible into Common Stock
which do not contain a beneficial ownership limitation.

Section
3. Certain Adjustments.


 


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


 


b)
[Reserved].


 


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)
[Reserved]


 


e)
[Reserved]


 


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 mail to the Holder 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, any sale or transfer of all or substantially all of the assets of the Company, or any compulsory share exchange whereby
the Common Stock is converted into other securities, cash or property, or (E) the Company shall authorize the voluntary or involuntary
dissolution, liquidation or winding up of the affairs of the Company, then, in each case, the Company shall cause to be mailed
to the Holder at its last address as it shall appear upon the Warrant Register of the Company, at least 20 calendar days prior
to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken
for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as
of which the holders of the Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants
are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is
expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall
be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer or share exchange; provided that the failure to mail such notice or any defect therein or
in the mailing thereof shall not affect the validity of the corporate action required to be specified in such notice. To the extent
that any notice provided hereunder constitutes, or contains, material, non-public information regarding the Company or any of
the Subsidiaries, the Company shall simultaneously file such notice with the Commission pursuant to a Current Report on Form 8-K.
The Holder shall remain entitled to exercise 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. Subject to compliance with any applicable securities laws and the conditions set forth in Section 4(d)
hereof and to the provisions of the Purchase Agreement, this Warrant and all rights hereunder 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 the Holder
delivers an assignment form to the Company assigning this Warrant full. The Warrant, if properly assigned in accordance herewith,
may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.


 


b)
New Warrants. 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 Exercise 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.


 


d)
Transfer Restrictions. This Warrant may be offered for sale, sold, transferred or assigned without the consent of the Company
in accordance with an exemption from registration under the Securities Act of 1933 and applicable state securities laws.


 




    	7



    	 



    




 


e)
Representation by the Holder. The Holder, by the acceptance hereof, represents and warrants that it is acquiring this Warrant
and, upon any exercise hereof, will acquire the Warrant Shares issuable upon such exercise, for its own account and not with a
view to or for distributing or reselling such Warrant Shares or any part thereof in violation of the Securities Act or any applicable
state securities law, except pursuant to sales registered or exempted under the Securities Act.


 


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.


 


d)
[Reserved].


 


e)
Jurisdiction. All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall
be determined in accordance with the provisions of the Purchase Agreement.


 


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, 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 damages in excess of $5,000 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.


 




    	 8



    	 



    




 


h)
Notices. Any notice, request or other document required or permitted to be given or delivered to the Holder by the Company
shall be delivered in accordance with the notice provisions of the Purchase Agreement.


 


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 remedies provided in this Warrant shall be cumulative and in addition to all other remedies available under
this Warrant and the other Transaction Documents, at law or in equity (including a decree of specific performance and/or other
injunctive relief or ensuring performance of any obligation herein or preventing a breach of any obligation herein), and nothing
herein shall limit the right of the Holder to pursue actual and consequential damages for any failure by the Company to comply
with the terms of this Warrant. The Company covenants to the Holder that there shall be no characterization concerning this instrument
other than as expressly provided herein. Amounts set forth or provided for herein with respect to payments, exercises and the
like (and the computation thereof) shall be the amounts to be received by the Holder and shall not, except as expressly provided
herein, be subject to any other obligation of the Company (or the performance thereof). The Company acknowledges that a breach
by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such breach may
be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the holder of this Warrant
shall be entitled, in addition to all other available remedies, to specific performance and an injunction restraining any breach,
without the necessity of showing economic loss and without any bond or other security being required. The Company shall provide
all information and documentation to the Holder that is requested by the Holder to enable the Holder to confirm the Company’s
compliance with the terms and conditions of this Warrant. The issuance of shares and certificates for shares as contemplated hereby
upon the exercise of this Warrant shall be made without charge to the Holder or such shares for any issuance tax or other costs
in respect thereof, provided that the Company shall not be required to pay any tax which may be payable in respect of any transfer
involved in the issuance and delivery of any certificate in a name other than the Holder or its agent on its behalf. If (a) this
Warrant is placed in the hands of an attorney for collection or enforcement or is collected or enforced through any legal proceeding
or the holder otherwise takes action to collect amounts due under this Warrant or to enforce the provisions of this Warrant or
(b) there occurs any bankruptcy, reorganization, receivership of the company or other proceedings affecting company creditors’
rights and involving a claim under this Warrant, then the Company shall pay the costs incurred by the Holder for such collection,
enforcement or action or in connection with such bankruptcy, reorganization, receivership or other proceeding, including, without
limitation, attorneys’ fees and disbursements.


 


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.


 




    	9



    	 



    




 


l)
Amendment. This Warrant (other than Section 2(f)) may be modified or amended or the provisions hereof waived with the written
consent of the Company and (i) a majority of the Holders of the Warrants issued under the Purchase Agreement, or (ii) Cavalry
Fund 1 LP if it still holds any Warrants. No consideration (other than reimbursement of legal fees) shall be offered or paid to
any Person to amend or consent to a waiver or modification of any provision of any of the Transaction Documents (as defined in
the Purchase Agreement) unless the same consideration also is offered to all of the parties to the Transaction Documents. No waiver
shall be effective unless it is in writing and signed by an authorized representative of the waiving party.


 


m)
Severability. If any provision of this Warrant is prohibited by law or otherwise determined to be invalid or unenforceable
by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed
amended to apply to the broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such
provision shall not affect the validity of the remaining provisions of this Warrant so long as this Warrant as so modified continues
to express, without material change, the original intentions of the parties as to the subject matter hereof and the prohibited
nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations
or reciprocal obligations of the parties or the practical realization of the benefits that would otherwise be conferred upon the
parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s)
with a valid provision(s), the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable
provision(s).


 


n)
Headings. This Warrant shall be deemed to be jointly drafted by the Company and the Holder and shall not be construed against
any Person as the drafter hereof. The headings of this Warrant are for convenience of reference and shall not form part of, or
affect the interpretation of, this Warrant. Terms used in this Warrant but defined in the other Transaction Documents shall have
the meanings ascribed to such terms on the Closing Date in such other Transaction Documents unless otherwise consented to in writing
by the Holder.


 


o)
Governing Law. This Warrant shall be governed by and construed and enforced in accordance with, and all questions concerning
the construction, validity, interpretation and performance of this Warrant shall be governed by, the internal laws of the State
of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York
or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York.
The Company 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 to the Company at the address set forth on its signature page to the Purchase Agreement
and agrees that such service shall constitute good and sufficient service of process and notice thereof. The Company 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 brought in an inconvenient forum or that
the venue of such suit, action or proceeding is improper. Nothing contained herein shall be deemed to limit in any way any right
to serve process in any manner permitted by law. Nothing contained herein shall be deemed or operate to preclude the Holder from
bringing suit or taking other legal action against the Company in any other jurisdiction to collect on the Company’s obligations
to the Holder, to realize on any collateral or any other security for such obligations, or to enforce a judgment or other court
ruling in favor of the Holder. THE COMPANY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE TO, AND AGREES NOT TO REQUEST, A
JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS WARRANT OR ANY TRANSACTION
CONTEMPLATED HEREBY.

(A)
In the case of a dispute relating to the Exercise Price, the closing sale price, fair market value or the arithmetic calculation
of the number of Warrant Shares (as the case may be) (including, without limitation, a dispute relating to the determination of
any of the foregoing), the Company or the Holder (as the case may be) shall submit the dispute to the other party via email (A)
if by the Company, within two (2) Business Days after the occurrence of the circumstances giving rise to such dispute or (B) if
by the Holder, at any time after the Holder learned of the circumstances giving rise to such dispute. If the Holder and the Company

or such arithmetic calculation of the number of Warrant Shares (as the case may be), at any time after the second (2nd)
Business Day following such initial notice by the Company or the Holder (as the case may be) of such dispute to the Company or
the Holder (as the case may be), then the Holder may, at its sole option, select an independent, reputable investment bank to
resolve such dispute.


 


(B)
The Holder and the Company shall each deliver to such investment bank (A) a copy of the initial dispute submission so delivered
in accordance with the first sentence of this Section 5(o) and (B) written documentation supporting its position with respect
to such dispute, in each case, no later than 5:00 p.m. (New York time) by the fifth (5th) Business Day immediately
following the date on which the Holder selected such investment bank (the “Dispute Submission Deadline”) (the
documents referred to in the immediately preceding clauses (A) and (B) are collectively referred to herein as the “Required
Dispute Documentation”) (it being understood and agreed that if either the Holder or the Company fails to so deliver
all of the Required Dispute Documentation by the Dispute Submission Deadline, then the party who fails to so submit all of the
Required Dispute Documentation shall no longer be entitled to (and hereby waives its right to) deliver or submit any written documentation
or other support to such investment bank with respect to such dispute and such investment bank shall resolve such dispute based
solely on the Required Dispute Documentation that was delivered to such investment bank prior to the Dispute Submission Deadline).
Unless otherwise agreed to in writing by both the Company and the Holder or otherwise requested by such investment bank, neither
the Company nor the Holder shall be entitled to deliver or submit any written documentation or other support to such investment
bank in connection with such dispute (other than the Required Dispute Documentation).

(C)
The Company and the Holder shall cause such investment bank to determine the resolution of such dispute and notify the Company
and the Holder of such resolution no later than ten (10) Business Days immediately following the Dispute Submission Deadline.
Such investment bank’s resolution of such dispute shall be final and binding upon all parties absent manifest error. If
such investment bank’s resolution differs by less than 5% from the Company’s proposed determination, the fees and
expenses of such investment bank shall be borne by the Holder, and if such investment bank’s resolution differs by more
than 5% from the Company’s proposed determination, the fees and expenses of such investment bank shall be borne by the Company.
