hereof or its permitted assigns (the “Holder”), is entitled, subject to the terms set forth below, to purchase

1.           EXERCISE
OF WARRANT.


 


(a)          Mechanics
of Exercise. Subject to the terms and conditions hereof (including, without limitation, the limitations set forth in Section 1(f)),
this Warrant may be exercised by the Holder on any day on or after the Issuance Date (an “Exercise Date”), in
whole or in part, by delivery (whether via facsimile or otherwise) of a written notice, in the form attached hereto as Exhibit
A (the “Exercise Notice”), of the Holder’s election to exercise this Warrant. Within one (1) Trading
Day following an exercise of this Warrant as aforesaid, the Holder shall deliver payment to the Company of an amount equal to the
Exercise Price in effect on the date of such exercise multiplied by the number of Warrant Shares as to which this Warrant was so
exercised (the “Aggregate Exercise Price”) in cash or via wire transfer of immediately available funds if the
Holder did not notify the Company in such Exercise Notice that such exercise was made pursuant to a Cashless Exercise (as defined
in Section 1(d)). The Holder shall not be required to deliver the original of this Warrant in order to effect an exercise
hereunder. Execution and delivery of an Exercise Notice with respect to less than all of the Warrant Shares shall have the same
effect as cancellation of the original of this Warrant and issuance of a new Warrant evidencing the right to purchase the remaining
number of Warrant Shares. Execution and delivery of an Exercise Notice for all of the then-remaining Warrant Shares shall have
the same effect as cancellation of the original of this Warrant after delivery of the Warrant Shares in accordance with the terms
hereof. On or before the first (1st) Trading Day following the date on which the Company has received an Exercise Notice,
the Company shall transmit by facsimile or electronic mail the transfer agent instructions and representation as to whether such
shares of Common Stock may then be resold pursuant to (A) an effective and available registration statement, (B) Rule 144 (as defined
in the Securities Purchase Agreement) if the Holder indicates on the applicable Exercise Notice that the shares of Common Stock
issuable in connection with such Exercise Notice are being resold either (x) prior to, (y) contemporaneously with, or (z) within
ten (10) Trading Days after, as applicable, the date of the applicable Conversion Notice by the Holder, or (C) Rule 144 without
having to comply with the information requirements under Rule 144(c)(1) (each, a “Permitted Securities Transaction”),
in the form attached hereto as Exhibit B, to the Holder and the Company’s transfer agent (the “Transfer
Agent”), which shall instruct the Transfer Agent to process such Exercise Notice in accordance with the terms herein.
On or before the second (2nd) Trading Day following the date on which the Company has received such Exercise Notice (or such earlier
date as required pursuant to the 1934 Act or other applicable law, rule or regulation for the settlement of a trade of such Warrant
Shares initiated on the applicable Exercise Date), the Company shall (X) provided that the Transfer Agent is participating in The
Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program and such shares of Common Stock
may then be resold by the Holder pursuant to a Permitted Securities Transaction, credit such aggregate number of shares of Common
Stock to which the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s balance account with
DTC through its Deposit/Withdrawal at Custodian system, or (Y) if the Transfer Agent is not participating in the DTC Fast Automated
Securities Transfer Program or such shares of Common Stock may not then be resold by the Holder pursuant to a Permitted Securities
Transaction, issue and deliver (via reputable overnight courier) to the address as specified in the Exercise Notice, a certificate,
registered in the name of the Holder or its designee, for the number of shares of Common Stock to which the Holder shall be entitled
pursuant to such exercise. Upon delivery of an Exercise Notice, 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 such
Warrant Shares are credited to the Holder’s DTC account or the date of delivery of the certificates evidencing such Warrant
Shares (as the case may be). If this Warrant is submitted in connection with any exercise pursuant to this Section 1(a) and
the number of Warrant Shares represented by this Warrant submitted for exercise is greater than the number of Warrant Shares being
acquired upon an exercise and upon surrender of this Warrant to the Company by the Holder, then, at the request of the Holder,
the Company shall as soon as practicable and in no event later than two (2) Business Days after any exercise and at its own expense,
issue and deliver to the Holder (or its designee) a new Warrant (in accordance with Section 7(d)) representing the right to
purchase the number of Warrant Shares purchasable immediately prior to such exercise under this Warrant, less the number of Warrant
Shares with respect to which this Warrant is exercised. No fractional shares of Common Stock are to be issued upon the exercise
of this Warrant, but rather the number of shares of Common Stock to be issued shall be rounded up to the nearest whole number.
The Company shall pay any and all transfer, stamp, issuance and similar taxes, costs and expenses (including, without limitation,
fees and expenses of the Transfer Agent) that may be payable with respect to the issuance and delivery of Warrant Shares upon exercise
of this Warrant. Notwithstanding the foregoing, except in the case where an exercise of this Warrant is validly made pursuant to
a Cashless Exercise), the Company’s failure to deliver Warrant Shares to the Holder on or prior to the later of ((i) two
(2) Trading Days after receipt of the applicable Exercise Notice (or such earlier date as required pursuant to the 1934 Act or
other applicable law, rule or regulation for the settlement of a trade of such Warrant Shares initiated on the applicable Exercise
Date) and (ii) one (1) Trading Day after the Company’s receipt of the Aggregate Exercise Price (or valid notice of a Cashless
Exercise (such later date, the “Share Delivery Date”) shall not be deemed to be a breach of this Warrant. Notwithstanding
anything to the contrary contained in this Warrant or the Registration Rights Agreement, after the effective date of the Registration
Statement (as defined in the Registration Rights Agreement) and prior to the Holder’s receipt of the notice of a Grace Period
(as defined in the Registration Rights Agreement), the Company shall cause the Transfer Agent to deliver unlegended shares of Common
Stock to the Holder (or its designee) in connection with any sale of Registrable Securities (as defined in the Registration Rights
Agreement) with respect to which the Holder has entered into a contract for sale, and delivered a copy of the prospectus included
as part of the particular Registration Statement to the extent applicable, and for which the Holder has not yet settled. From the
Issuance Date through and including the Expiration Date, the Company shall maintain a transfer agent that participates in the DTC’s
Fast Automated Securities Transfer Program.

(b)          Exercise
Price. For purposes of this Warrant, “Exercise Price” means $1.12, subject to adjustment as provided herein.


 


(c)          Company’s
Failure to Timely Deliver Securities. If the Company shall fail, for any reason or for no reason, on or prior to the Share
Delivery Date, either (I) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program or such
applicable shares of Common Stock may not then be resold by the Holder pursuant to a Permitted Securities Transaction, to credit
the balance account of the Holder or the Holder’s designee with DTC for such number of Warrant Shares to which the Holder
is entitled upon the Holder’s exercise of this Warrant (as the case may be) or (II) if a Registration Statement covering
the resale of the Warrant Shares that are the subject of the Exercise Notice (the “Unavailable Warrant Shares”)
is not available for the resale of such Unavailable Warrant Shares and the Company fails to promptly, but in no event later than
as required pursuant to the Registration Rights Agreement (x) so notify the Holder and (y) deliver the Warrant Shares electronically
without any restrictive legend by crediting such aggregate number of Warrant Shares to which the Holder is entitled pursuant to
such exercise to the Holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal At Custodian
system (the event described in the immediately foregoing clause (II) is hereinafter referred as a “Notice Failure”
and together with the event described in clause (I) above, a “Delivery Failure”), then, in addition to all other
remedies available to the Holder, (X) the Company shall pay in cash to the Holder on each day after the Share Delivery Date and
during such Delivery Failure an amount equal to 1.25% of the product of (A) the sum of the number of shares of Common Stock not
issued to the Holder on or prior to the Share Delivery Date and to which the Holder is entitled, multiplied by (B) any trading
price of the Common Stock selected by the Holder in writing as in effect at any time during the period beginning on the applicable
Exercise Date and ending on the applicable Share Delivery Date, and (Y) the Holder, upon written notice to the Company, may void
its Exercise Notice with respect to, and retain or have returned, as the case may be, any portion of this Warrant that has not
been exercised pursuant to such Exercise Notice; provided that the voiding of an Exercise Notice shall not affect the Company’s
obligations to make any payments which have accrued prior to the date of such notice pursuant to this Section 1(c) or otherwise.
In addition to the foregoing, if on or prior to the Share Delivery Date either (I) the Transfer Agent is not participating in the
DTC Fast Automated Securities Transfer Program or such applicable shares of Common Stock may not then be resold by the Holder pursuant
to a Permitted Securities Transaction, the Company shall fail to issue and deliver to the Holder (or its designee) a certificate
and register such shares of Common Stock on the Company’s share register or, if the Transfer Agent is participating in the
DTC Fast Automated Securities Transfer Program and such applicable shares of Common Stock may then be resold by the Holder pursuant
to a Permitted Securities Transaction, the Transfer Agent shall fail to credit the balance account of the Holder or the Holder’s
designee with DTC for the number of shares of Common Stock to which the Holder is entitled upon the Holder’s exercise hereunder
or pursuant to the Company’s obligation pursuant to clause (ii) below or (II) a Notice Failure occurs, and if on or after
such Share Delivery Date the Holder purchases (in an open market transaction or otherwise) shares of Common Stock corresponding
to all or any portion of the number of shares of Common Stock issuable upon such exercise that the Holder is entitled to receive
from the Company and has not received from the Company in connection with such Delivery Failure or Notice Failure, as applicable
(a “Buy-In”), then, in addition to all other remedies available to the Holder, the Company shall, within two
(2) Business Days after the Holder’s request and in the Holder’s discretion, either (i) pay cash to the Holder in an
amount equal to the Holder’s total purchase price (including brokerage commissions and other out-of-pocket expenses, if any)
for the shares of Common Stock so purchased (including, without limitation, by any other Person in respect, or on behalf, of the
Holder) (the “Buy-In Price”), at which point the Company’s obligation to so issue and deliver such certificate
(and to issue such shares of Common Stock) or credit the balance account of such Holder or such Holder’s designee, as applicable,
with DTC for the number of Warrant Shares to which the Holder is entitled upon the Holder’s exercise hereunder (as the case
may be) (and to issue such Warrant Shares) shall terminate, or (ii) promptly honor its obligation to so issue and deliver to the
Holder a certificate or certificates representing such Warrant Shares or credit the balance account of such Holder or such Holder’s
designee, as applicable, with DTC for the number of Warrant Shares to which the Holder is entitled upon the Holder’s exercise
hereunder (as the case may be) and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the
product of (A) such number of Warrant Shares multiplied by (B) the lowest Closing Sale Price of the Common Stock on any Trading
Day during the period commencing on the date of the applicable Exercise Notice and ending on the date of such issuance and payment
under this clause (ii) (the “Buy-In Payment Amount”). Nothing shall limit the 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 certificates representing shares of Common
Stock (or to electronically deliver such shares of Common Stock) upon the exercise of this Warrant as required pursuant to the
terms hereof. In addition to the foregoing rights, (i) if the Company fails to deliver the applicable number of Warrant Shares
upon an exercise pursuant to Section 1 by the applicable Share Delivery Date, then the Holder shall have the right to rescind such
exercise in whole or in part and retain and/or have the Company return, as the case may be, any portion of this Warrant that has
not been exercised pursuant to such Exercise Notice; provided that the rescission of an exercise shall not affect the Company’s
obligation to make any payments that have accrued prior to the date of such notice pursuant to this Section 1(c) or otherwise,
and (ii) if a registration statement covering the issuance or resale of the Warrant Shares that are subject to an Exercise Notice
is not available for the issuance or resale, as applicable, of such Exercise Notice Warrant Shares and the Holder has submitted
an Exercise Notice prior to receiving notice of the non-availability of such registration statement and the Company has not already
delivered the Warrant Shares underlying such Exercise Notice electronically without any restrictive legend by crediting such aggregate
number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s
balance account with DTC through its Deposit / Withdrawal At Custodian system, the Holder shall have the option, by delivery of
notice to the Company, to (x) rescind such Exercise Notice in whole or in part and retain or have returned, as the case may be,
any portion of this Warrant that has not been exercised pursuant to such Exercise Notice; provided that the rescission of an Exercise
Notice shall not affect the Company’s obligation to make any payments that have accrued prior to the date of such notice
pursuant to this Section 1(c) or otherwise, and/or (y) switch some or all of such Exercise Notice from a cash exercise to a Cashless
Exercise.


 




    	 	3	 



     


    

 


(d)          Cashless
Exercise. Notwithstanding anything contained herein to the contrary (other than Section 1(f) below), if, after the six
month anniversary of the Issuance date, at the time of exercise hereof a Registration Statement (as defined in the Registration
Rights Agreement (as defined in the Securities Purchase Agreement)) is not effective (or the prospectus contained therein is not
available for use) for the resale by the Holder of the number of Warrant Shares subject to such exercise, then the Holder may,
in its sole discretion, exercise this Warrant with respect to such number of Warrant Shares, in lieu of making the cash payment
otherwise contemplated to be made to the Company upon such exercise in payment of the Aggregate Exercise Price, elect instead to
receive upon such exercise the “Net Number” of Warrant Shares determined according to the following formula (a “Cashless
Exercise”):


 


Net Number = (A x B) - (A x C)


       D


 


For purposes of the
foregoing formula:


 


A= the total number of shares with
respect to which this Warrant is then being exercised.


 


B = the quotient of (x) the sum
of the VWAP of the Common Stock of each of the twenty (20) Trading Days ending at the close of business on the Principal Market
immediately prior to the time of exercise as set forth in the applicable Exercise Notice, divided by (y) twenty (20).


 


C = the
Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise.


 


D = as applicable: (i) the Closing
Sale Price of the Common Stock on the Trading Day immediately preceding the date of the applicable Exercise Notice if such Exercise
Notice is (1) both executed and delivered pursuant to Section 1(a) hereof on a day that is not a Trading Day or (2) both executed
and delivered pursuant to Section 1(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) the Bid
Price of the Common Stock as of the time of the Holder’s execution of the applicable Exercise Notice if such Exercise Notice
is executed during “regular trading hours” on a Trading Day and is delivered within two (2) hours thereafter pursuant
to Section 1(a) hereof, or (iii) the Closing Sale Price of the Common Stock on the date of the applicable Exercise Notice
if the date of such Exercise Notice is a Trading Day and such Exercise Notice is both executed and delivered pursuant to Section 1(a)
hereof after the close of “regular trading hours” on such Trading Day.


 


For purposes of Rule
144(d) promulgated under the 1933 Act, as in effect on the Subscription Date, it is intended that the Warrant Shares issued in
a Cashless Exercise shall be deemed to have been acquired by the Holder, and the holding period for the Warrant Shares shall be
deemed to have commenced, on the date this Warrant was originally issued pursuant to the Securities Purchase Agreement.


 


(e)          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 13.


 




    	 	4	 



     


    

 


(f)           Limitations
on Exercises.


 


(i)          Beneficial
Ownership. The Company shall not effect the exercise of any portion of this Warrant, and the Holder shall not have the right
to exercise any portion of this Warrant, pursuant to the terms and conditions of this Warrant and any such exercise shall be null
and void and treated as if never made, to the extent that after giving effect to such exercise, the Holder together with the other
Attribution Parties collectively would beneficially own in excess of 4.99% (the “Maximum Percentage”) of the
shares of Common Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the
aggregate number of shares of Common Stock beneficially owned by the Holder and the other Attribution Parties shall include the
number of shares of Common Stock held by the Holder and all other Attribution Parties plus the number of shares of Common Stock
issuable upon exercise of this Warrant with respect to which the determination of such sentence is being made, but shall exclude
shares of Common Stock which would be issuable upon (A) exercise of the remaining, unexercised portion of this Warrant beneficially
owned by the Holder or any of the other Attribution Parties and (B) exercise or conversion of the unexercised or unconverted portion
of any other securities of the Company (including, without limitation, any convertible notes or convertible preferred stock or
warrants, including other SPA Warrants) beneficially owned by the Holder or any other Attribution Party subject to a limitation
on conversion or exercise analogous to the limitation contained in this Section 1(f)(i). For purposes of this Section 1(f)(i),
beneficial ownership shall be calculated in accordance with Section 13(d) of the 1934 Act. For purposes of determining the number
of outstanding shares of Common Stock the Holder may acquire upon the exercise of this Warrant without exceeding the Maximum Percentage,
the Holder may rely on the number of outstanding shares of Common Stock as reflected in (x) the Company’s most recent Annual
Report on Form 10-K, Quarterly Report on Form 10-Q, Current Report on Form 8-K or other public filing with the SEC, as the case
may be, (y) a more recent public announcement by the Company or (z) any other written notice by the Company or the Transfer Agent,
if any, setting forth the number of shares of Common Stock outstanding (the “Reported Outstanding Share Number”).
If the Company receives an Exercise Notice from the Holder at a time when the actual number of outstanding shares of Common Stock
is less than the Reported Outstanding Share Number, the Company shall (i) notify the Holder in writing of the number of shares
of Common Stock then outstanding and, to the extent that such Exercise Notice would otherwise cause the Holder’s beneficial
ownership, as determined pursuant to this Section 1(f)(i), to exceed the Maximum Percentage, the Holder must notify the Company
of a reduced number of Warrant Shares to be acquired pursuant to such Exercise Notice (the number of shares by which such purchase
is reduced, the “Reduction Shares”) and (ii) as soon as reasonably practicable, the Company shall return to
the Holder any exercise price paid by the Holder for the Reduction Shares. For any reason at any time, upon the written or oral
request of the Holder, the Company shall within one (1) Business Day confirm orally and in writing or by electronic mail 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
and any other Attribution Party since the date as of which the Reported Outstanding Share Number was reported. In the event that
the issuance of shares of Common Stock to the Holder upon exercise of this Warrant results in the Holder and the other Attribution
Parties being deemed to beneficially own, in the aggregate, more than the Maximum Percentage of the number of outstanding shares
of Common Stock (as determined under Section 13(d) of the 1934 Act), the number of shares so issued by which the Holder’s
and the other Attribution Parties’ aggregate beneficial ownership exceeds the Maximum Percentage (the “Excess Shares”)
shall be deemed null and void and shall be cancelled ab initio, and the Holder shall not have the power to vote or to transfer
the Excess Shares. As soon as reasonably practicable after the issuance of the Excess Shares has been deemed null and void, the
Company shall return to the Holder the exercise price paid by the Holder for the Excess Shares. Upon delivery of a written notice
to the Company, the Holder may from time to time increase (with such increase not effective until the sixty-first (61st)
day after delivery of such notice) or decrease the Maximum Percentage to any other percentage not in excess of 9.99% as specified
in such notice; provided that (i) any such increase in the Maximum Percentage will not be effective until the sixty-first (61st)
day after such notice is delivered to the Company and (ii) any such increase or decrease will apply only to the Holder and the
other Attribution Parties and not to any other holder of SPA Warrants that is not an Attribution Party of the Holder. For purposes
of clarity, the shares of Common Stock issuable pursuant to the terms of this Warrant in excess of the Maximum Percentage shall
not be deemed to be beneficially owned by the Holder for any purpose including for purposes of Section 13(d) or Rule 16a-1(a)(1)
of the 1934 Act. No prior inability to exercise this Warrant pursuant to this paragraph shall have any effect on the applicability
of the provisions of this paragraph with respect to any subsequent determination of exercisability. The provisions of this paragraph
shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 1(f)(i) to the
extent necessary to correct this paragraph or any portion of this paragraph which may be defective or inconsistent with the intended
beneficial ownership limitation contained in this Section 1(f)(i) or to make changes or supplements necessary or desirable to properly
give effect to such limitation. The limitation contained in this paragraph may not be waived and shall apply to a successor holder
of this Warrant.


 




    	 	5	 



     


    

 


(ii)         Investor
Prepayment Limitations. Notwithstanding any provision of this Warrant to the contrary, no more than the Maximum Eligibility
Number of Warrant Shares shall be exercisable hereunder.


 


(g)          Reservation
of Shares.


 


(i)          Required
Reserve Amount. So long as this Warrant remains outstanding, the Company shall at all times keep reserved for issuance under
this Warrant a number of shares of Common Stock at least equal to 200% of the maximum number of shares of Common Stock as shall
be necessary to satisfy the Company’s obligation to issue shares of Common Stock under the SPA Warrants then outstanding
(without regard to any limitations on exercise) (the “Required Reserve Amount”); provided that at no time shall
the number of shares of Common Stock reserved pursuant to this Section 1(g)(i) be reduced other than proportionally in connection
with any exercise or redemption of SPA Warrants or such other event covered by Section 2(a) below. The Required Reserve Amount
(including, without limitation, each increase in the number of shares so reserved) shall be allocated pro rata among the holders
of the SPA Warrants based on number of shares of Common Stock issuable upon exercise of SPA Warrants held by each holder on the
Closing Date (without regard to any limitations on exercise) or increase in the number of reserved shares, as the case may be (the
“Authorized Share Allocation”). In the event that a holder shall sell or otherwise transfer any of such holder’s
SPA Warrants, each transferee shall be allocated a pro rata portion of such holder’s Authorized Share Allocation. Any shares
of Common Stock reserved and allocated to any Person which ceases to hold any SPA Warrants shall be allocated to the remaining
holders of SPA Warrants, pro rata based on the number of shares of Common Stock issuable upon exercise of the SPA Warrants then
held by such holders (without regard to any limitations on exercise).


 




    	 	6	 



     


    

 


(ii)         Insufficient
Authorized Shares. If, notwithstanding Section 1(g)(i) above, and not in limitation thereof, at any time while any of the SPA
Warrants remain outstanding, the Company does not have a sufficient number of authorized and unreserved shares of Common Stock
to satisfy its obligation to reserve the Required Reserve Amount (an “Authorized Share Failure”), then the Company
shall immediately take all action necessary to increase the Company’s authorized shares of Common Stock to an amount sufficient
to allow the Company to reserve the Required Reserve Amount for all the SPA Warrants then outstanding. Without limiting the generality
of the foregoing sentence, as soon as practicable after the date of the occurrence of an Authorized Share Failure, but in no event
later than sixty (60) days after the occurrence of such Authorized Share Failure, the Company shall hold a meeting of its stockholders
for the approval of an increase in the number of authorized shares of Common Stock. In connection with such meeting, the Company
shall provide each stockholder with a proxy statement and shall use its best efforts to solicit its stockholders’ approval
of such increase in authorized shares of Common Stock and to cause its board of directors to recommend to the stockholders that
they approve such proposal. In the event that the Company is prohibited from issuing shares of Common Stock upon an exercise of
this Warrant due to the failure by the Company to have sufficient shares of Common Stock available out of the authorized but unissued
shares of Common Stock (such unavailable number of shares of Common Stock, the “Authorization Failure Shares”),
in lieu of delivering such Authorization Failure Shares to the Holder, the Company shall pay cash in exchange for the cancellation
of such portion of this Warrant exercisable into such Authorization Failure Shares at a price equal to the sum of (i) the product
of (x) such number of Authorization Failure Shares and (y) the greatest Closing Sale Price of the Common Stock on any Trading Day
during the period commencing on the date the Holder delivers the applicable Exercise Notice with respect to such Authorization
Failure Shares to the Company and ending on the date of such issuance and payment under this Section 1(g)(ii); and (ii) to the
extent the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a
sale by the Holder of Authorization Failure Shares, any Buy-In Payment Amount, brokerage commissions and other out-of-pocket expenses,
if any, of the Holder incurred in connection therewith. Nothing contained in this Section 1(g)(ii) shall limit any obligations
of the Company under any provision of the Securities Purchase Agreement.


 




    	 	7	 



     


    

 


2.           ADJUSTMENT
OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The Exercise Price and number of Warrant
Shares issuable upon exercise of this Warrant are subject to adjustment from time to time as set forth in this Section 2.


 


(a)          Stock
Dividends and Splits. Without limiting any provision of Section 2(b) or Section 4, if the Company, at any time on
or after the Subscription Date, (i) pays a stock dividend on one or more classes of its then outstanding shares of Common Stock
or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides (by
any stock split, stock dividend, recapitalization or otherwise) one or more classes of its then outstanding shares of Common Stock
into a larger number of shares or (iii) combines (by combination, reverse stock split or otherwise) one or more classes of its
then outstanding shares of Common Stock into a smaller number of shares, then in each such case the Exercise Price shall be multiplied
by a fraction of which the numerator shall be the number of shares of Common Stock outstanding immediately before such event and
of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment
made pursuant to clause (i) of this paragraph shall become effective immediately after the record date for the determination of
stockholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph
shall become effective immediately after the effective date of such subdivision or combination. If any event requiring an adjustment
under this paragraph occurs during the period that an Exercise Price is calculated hereunder, then the calculation of such Exercise
Price shall be adjusted appropriately to reflect such event.


 


(b)          Adjustment
Upon Issuance of Shares of Common Stock. If and whenever on or after the Subscription Date, the Company issues or sells, or
in accordance with this Section 2 is deemed to have issued or sold, any shares of Common Stock (including the issuance or
sale of shares of Common Stock owned or held by or for the account of the Company, but excluding any Excluded Securities issued
or sold or deemed to have been issued or sold) for a consideration per share (the “New Issuance Price”) less
than a price equal to the Exercise Price in effect immediately prior to such issuance or sale or deemed issuance or sale (such
Exercise Price then in effect is referred to herein as the “Applicable Price”) (the foregoing a “Dilutive
Issuance”), then immediately after such Dilutive Issuance, the Exercise Price then in effect shall be reduced to an amount
equal to the New Issuance Price. For all purposes of the foregoing (including, without limitation, determining the Exercise Price
after giving effect to this Section 2 and the New Issuance Price under this Section 2(b)), the following shall be applicable:


 




    	 	8	 



     


    

 


(i)          Issuance
of Options. If the Company in any manner grants or sells any Options and the lowest price per share for which one share of
Common Stock is at any time issuable upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible
Securities issuable upon exercise of any such Option or otherwise pursuant to the terms thereof is less than the Applicable Price,
then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of
the granting or sale of such Option for such price per share. For purposes of this Section 2(b)(i), the “lowest price
per share for which one share of Common Stock is at any time issuable upon the exercise of any such Option or upon conversion,
exercise or exchange of any Convertible Securities issuable upon exercise of any such Option or otherwise pursuant to the terms
thereof” shall be equal to (1) the lower of (x) the sum of the lowest amounts of consideration (if any) received or receivable
by the Company with respect to any one share of Common Stock upon the granting or sale of such Option, upon exercise of such Option
and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise of such Option or otherwise pursuant
to the terms thereof and (y) the lowest exercise price set forth in such Option for which one share of Common Stock is issuable
(or may become issuable assuming all possible market conditions) upon the exercise of any such Options or upon conversion, exercise
or exchange of any Convertible Securities issuable upon exercise of any such Option or otherwise pursuant to the terms thereof,
minus (2) the sum of all amounts paid or payable to the holder of such Option (or any other Person) with respect to any one share
of Common Stock upon the granting or sale of such Option, upon exercise of such Option and upon conversion, exercise or exchange
of any Convertible Security issuable upon exercise of such Option or otherwise pursuant to the terms thereof plus the value of
any other consideration received or receivable by, or benefit conferred on, the holder of such Option (or any other Person). Except
as contemplated below, no further adjustment of the Exercise Price shall be made upon the actual issuance of such shares of Common
Stock or of such Convertible Securities upon the exercise of such Options or otherwise pursuant to the terms thereof or upon the
actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible Securities.


 


(ii)         Issuance
of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities and the lowest price per
share for which one share of Common Stock is at any time issuable upon the conversion, exercise or exchange thereof or otherwise
pursuant to the terms thereof is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding
and to have been issued and sold by the Company at the time of the issuance or sale of such Convertible Securities for such price
per share. For the purposes of this Section 2(b)(ii), the “lowest price per share for which one share of Common Stock
is at any time issuable upon the conversion, exercise or exchange thereof or otherwise pursuant to the terms thereof” shall
be equal to (1) the lower of (x) the sum of the lowest amounts of consideration (if any) received or receivable by the Company
with respect to one share of Common Stock upon the issuance or sale of the Convertible Security and upon conversion, exercise or
exchange of such Convertible Security or otherwise pursuant to the terms thereof and (y) the lowest conversion price set forth
in such Convertible Security for which one share of Common Stock is issuable (or may become issuable assuming all possible market
conditions) upon conversion, exercise or exchange thereof or otherwise pursuant to the terms thereof, minus (2) the sum of all
amounts paid or payable to the holder of such Convertible Security (or any other Person) with respect to any one share of Common
Stock upon the issuance or sale of such Convertible Security plus the value of any other consideration received or receivable by,
or benefit conferred on, the holder of such Convertible Security (or any other Person). Except as contemplated below, no further
adjustment of the Exercise Price shall be made upon the actual issuance of such shares of Common Stock upon conversion, exercise
or exchange of such Convertible Securities or otherwise pursuant to the terms thereof, and if any such issuance or sale of such
Convertible Securities is made upon exercise of any Options for which adjustment the Exercise Price has been or is to be made pursuant
to other provisions of this Section 2(b), except as contemplated below, no further adjustment of the Exercise Price shall
be made by reason of such issuance or sale.


 




    	 	9	 



     


    

 


(iii)        Change
in Option Price or Rate of Conversion. If the purchase or exercise price provided for in any Options, the additional consideration,
if any, payable upon the issue, conversion, exercise or exchange of any Convertible Securities, or the rate at which any Convertible
Securities are convertible into or exercisable or exchangeable for shares of Common Stock increases or decreases at any time (other
than proportional changes in conversion or exercise prices, as applicable, in connection with an event referred to in Section 2(a)),
the Exercise Price in effect at the time of such increase or decrease shall be adjusted to the Exercise Price which would have
been in effect at such time had such Options or Convertible Securities provided for such increased or decreased purchase price,
additional consideration or increased or decreased conversion rate, as the case may be, at the time initially granted, issued or
sold. For purposes of this Section 2(b)(iii), if the terms of any Option or Convertible Security that was outstanding as of
the Subscription Date are increased or decreased in the manner described in the immediately preceding sentence, then such Option
or Convertible Security and the shares of Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed
to have been issued as of the date of such increase or decrease. No adjustment pursuant to this Section 2(b) shall be made
if such adjustment would result in an increase of the Exercise Price then in effect.


 




    	 	10	 



     


    

 


(iv)        Calculation
of Consideration Received. If any Option and/or Convertible Security and/or Adjustment Right is issued in connection with the
issuance or sale or deemed issuance or sale of any other securities of the Company (as determined by the Holder, the “Primary
Security”, and such Option and/or Convertible Security and/or Adjustment Right, the “Secondary Securities”,
and together with the Primary Security, each a “Unit”), together comprising one integrated transaction, (or
one or more transactions if such issuances or sales or deemed issuances or sales of securities of the Company either (A) have at
least one investor or purchaser in common, (B) are consummated in reasonable proximity to each other and/or (C) are consummated
under the same plan of financing) the aggregate consideration per share of Common Stock with respect to such Primary Security shall
be deemed to be equal to the lower of (x) the purchase price of such Unit, (y) if such Primary Security is an Option and/or Convertible
Security, the lowest price per share for which one share of Common Stock is at any time issuable upon the exercise or conversion
of the Primary Security in accordance with Section 2(a)(i) and 2(a)(ii) above and (z) the lowest VWAP of the Common Stock of any
Trading Day during the five (5) Trading Day period commencing on and including the later of (I) the Trading Day immediately following
the public announcement of such Dilutive Issuance and (II) solely if such Primary Security and Secondary Security are issued in
a private placement by the Company, the Trading Day any shares of Common Stock issuable upon conversion, exercise or exchange of
such Primary Security, Secondary Security and/or Unit, as applicable, is initially able to be resold by a non-affiliate of the
Company pursuant to Rule 144 (or, if earlier, the effective date of a registration statement registering for resale any shares
of Common Stock issuable upon conversion, exercise or exchange of such Primary Security, Secondary Security and/or Unit). If any
shares of Common Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the
consideration received therefor will be deemed to be the net amount of consideration received by the Company therefor. If any shares
of Common Stock, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of such consideration
received by the Company will be the fair value of such consideration, except where such consideration consists of publicly traded
securities, in which case the amount of consideration received by the Company for such securities will be the arithmetic average
of the VWAPs of such security for each of the five (5) Trading Days immediately preceding the date of receipt. If any shares of
Common Stock, Options or Convertible Securities are issued to the owners of the non-surviving entity in connection with any merger
in which the Company is the surviving entity, the amount of consideration therefor will be deemed to be the fair value of such
portion of the net assets and business of the non-surviving entity as is attributable to such shares of Common Stock, Options or
Convertible Securities (as the case may be). The fair value of any consideration other than cash or publicly traded securities
will be determined jointly by the Company and the Holder. If such parties are unable to reach agreement within ten (10) days after
the occurrence of an event requiring valuation (the “Valuation Event”), the fair value of such consideration
will be determined within five (5) Trading Days after the tenth (10th) day following such Valuation Event by an independent,
reputable appraiser jointly selected by the Company and the Holder. The determination of such appraiser shall be final and binding
upon all parties absent manifest error and the fees and expenses of such appraiser shall be borne by the Company.


 


(v)         Record
Date. If the Company takes a record of the holders of shares of Common Stock for the purpose of entitling them (A) to
receive a dividend or other distribution payable in shares of Common Stock, Options or in Convertible Securities or (B) to
subscribe for or purchase shares of Common Stock, Options or Convertible Securities, then such record date will be deemed to be
the date of the issuance or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such
dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase (as the
case may be).


 


(c)          Number
of Warrant Shares. Simultaneously with any adjustment to the Exercise Price pursuant to Section 2(a) above, the number
of Warrant Shares that may be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that
after such adjustment the aggregate Exercise Price payable hereunder for the adjusted number of Warrant Shares shall be the same
as the aggregate Exercise Price in effect immediately prior to such adjustment (without regard to any limitations on exercise contained
herein).


 




    	 	11	 



     


    

 


(d)          Holder’s
Right of Alternative Exercise Price Following Issuance of Certain Options or Convertible Securities. In addition to and not
in limitation of the other provisions of this Section 2, if the Company in any manner issues or sells or enters into any agreement
to issue or sell, any Common Stock, Options or Convertible Securities (any such securities, “Variable Price Securities”)
after the Subscription Date that are issuable pursuant to such agreement or convertible into or exchangeable or exercisable for
shares of Common Stock at a price which varies or may vary with the market price of the shares of Common Stock, including by way
of one or more reset(s) to a fixed price, but exclusive of such formulations reflecting customary anti-dilution provisions (such
as share splits, share combinations, share dividends and similar transactions) (each of the formulations for such variable price
being herein referred to as, the “Variable Price”), the Company shall provide written notice thereof via facsimile
and overnight courier to the Holder on the date of such agreement and the issuance of such Convertible Securities or Options. From
and after the date the Company enters into such agreement or issues any such Variable Price Securities, the Holder shall have the
right, but not the obligation, in its sole discretion to substitute the Variable Price for the Exercise Price upon exercise of
this Warrant by designating in the Exercise Notice delivered upon any exercise of this Warrant that solely for purposes of such
exercise the Holder is relying on the Variable Price rather than the Exercise Price then in effect. The Holder’s election
to rely on a Variable Price for a particular exercise of this Warrant shall not obligate the Holder to rely on a Variable Price
for any future exercises of this Warrant.


 


(e)          Stock
Combination Event Adjustment. If at any time and from time to time on or after the Issuance Date there occurs any stock split,
stock dividend, stock combination recapitalization or other similar transaction involving the Common Stock (each, a “Stock
Combination Event”, and such date thereof, the “Stock Combination Event Date”) and the Event Market
Price is less than the Exercise Price then in effect (after giving effect to the adjustment in clause 2(a) above), then on the
sixteenth (16th) Trading Day immediately following such Stock Combination Event, the Exercise Price then in effect on such sixteenth
(16th) Trading Day (after giving effect to the adjustment in clause 2(a) above) shall be reduced (but in no event increased) to
the Event Market Price. For the avoidance of doubt, if the adjustment in the immediately preceding sentence would otherwise result
in an increase in the Exercise Price hereunder, no adjustment shall be made.


 


(f)           Other
Events. In the event that the Company (or any Subsidiary (as defined in the Securities Purchase Agreement)) shall take any
action to which the provisions hereof are not strictly applicable, or, if applicable, would not operate to protect the Holder from
dilution or if any event occurs of the type contemplated by the provisions of this Section 2 but not expressly provided for by
such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights
with equity features), then the Company’s board of directors shall in good faith determine and implement an appropriate adjustment
in the Exercise Price and the number of Warrant Shares (if applicable) so as to protect the rights of the Holder, provided that
no such adjustment pursuant to this Section 2(f) will increase the Exercise Price or decrease the number of Warrant Shares as otherwise
determined pursuant to this Section 2, provided further that if the Holder does not accept such adjustments as appropriately protecting
its interests hereunder against such dilution, then the Company’s board of directors and the Holder shall agree, in good
faith, upon an independent investment bank of nationally recognized standing to make such appropriate adjustments, whose determination
shall be final and binding absent manifest error and whose fees and expenses shall be borne by the Company.


 




    	 	12	 



     


    

 


(g)          Calculations.
All calculations under this Section 2 shall be made by rounding to the nearest cent or the nearest 1/100th of a
share, as applicable. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held
by or for the account of the Company, and the disposition of any such shares shall be considered an issuance or sale of Common
Stock.


 


(h)          Voluntary
Adjustment By Company. The Company may at any time during the term of this Warrant, subject to the approval of the Principal
Market and with the prior written consent of the Required Holders (as defined in the Securities Purchase Agreement), 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.


 


(i)           Adjustment
Date Reset. No later than the first Trading Day after the occurrence of each of (i) the later of (x) the Stockholder Approval
Date (as defined in the Securities Purchase Agreement) and (y) the effective date of a registration statement registering for resale
by the Holder of less than all of the shares of Common Stock issued upon conversion of the Notes and Warrants held by the Holder,
(ii) the later of (x) the Stockholder Approval Date and (y) the Applicable Date (as defined in the Securities Purchase Agreement),
and (iii) the Stockholder Approval Date (each, an “Adjustment Date Event”), the Company shall notify the Holder
in writing of the occurrence of such Adjustment Date Event (each, an “Adjustment Date Event Notice”). With respect
to any given Adjustment Date Event, on the tenth (10th) Trading Day immediately following the later of (x) the Company’s
delivery of the applicable Adjustment Date Event Notice to the Holder with respect to such Adjustment Date Event (or, if the Company
fails to provide such Adjustment Date Event Notice to the Holder, upon the Holder’s delivery of written notice to the Company
that the Holder has become aware of the occurrence of such Adjustment Date Event) and (y) the date of occurrence of such Adjustment
Date Event (such later date, each an “Adjustment Date”), if the Exercise Price then in effect is greater than
the Adjusted Exercise Price, on the applicable Adjustment Date the Exercise Price shall automatically adjust to the Adjusted Exercise
Price.


 


(j)           Exercise
Floor Price. No adjustment pursuant to this Section 2 shall cause the Exercise Price to be less than $0.97 (as adjusted for
any stock dividend, stock split, stock combination, reclassification or similar transaction occurring after the date of the Securities
Purchase Agreement) (the “Exercise Floor Price”). Notwithstanding the foregoing, nothing contained in this Section
2(j) shall apply after Shareholder Approval (as defined in the Securities Purchase Agreement) is obtained and any adjustments hereunder
that, but for this Section 2(j), would have occurred prior to the Stockholder Approval Date, shall occur on the Stockholder Approval
Date.


 




    	 	13	 



     


    

 


3.           RIGHTS
UPON DISTRIBUTION OF ASSETS. In addition to any adjustments pursuant to Section 2 above, if the Company shall
declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to holders of shares of Common
Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities,
property, options, evidence of indebtedness or any other assets 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 or restrictions on exercise of this Warrant, including without limitation,
the Maximum Percentage) immediately before the date on 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 and the other Attribution Parties exceeding the Maximum Percentage, then the Holder shall not be entitled to participate
in such Distribution to the extent of the Maximum Percentage (and shall not be entitled to beneficial ownership of such shares
of Common Stock as a result of such Distribution (and beneficial ownership) to the extent of any such excess) and the portion
of such Distribution shall be held in abeyance for the benefit of the Holder until such time or times, if ever, as its right thereto
would not result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, at which time or times the
Holder shall be granted such Distribution (and any Distributions declared or made on such initial Distribution or on any subsequent
Distribution held similarly in abeyance) to the same extent as if there had been no such limitation).


 


4.           PURCHASE
RIGHTS; FUNDAMENTAL TRANSACTIONS.


 


(a)          Purchase
Rights. In addition to any adjustments pursuant to Section 2 above, if at any time the Company grants, issues or sells
any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to the record
holders of any class 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
or restrictions on exercise of this Warrant, including without limitation, the Maximum Percentage) 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, issuance or sale of such Purchase Rights
(provided, however, that to the extent that the Holder’s right to participate in any such Purchase Right would
result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, then the Holder shall not be entitled
to participate in such Purchase Right to the extent of the Maximum Percentage (and shall not be entitled to beneficial ownership
of such shares of Common Stock as a result of such Purchase Right (and beneficial ownership) to the extent of any such excess)
and such Purchase Right to such extent shall be held in abeyance for the benefit of the Holder until such time or times, if ever,
as its right thereto would not result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, at which
time or times the Holder shall be granted such right (and any Purchase Right granted, issued or sold on such initial Purchase Right
or on any subsequent Purchase Right held similarly in abeyance) to the same extent as if there had been no such limitation).


 




    	 	14	 



     


    

 


(b)          Fundamental
Transactions. The Company shall not enter into or be party to a Fundamental Transaction unless (i)  the Successor Entity
assumes in writing all of the obligations of the Company under this Warrant and the other Transaction Documents (as defined in
the Securities Purchase Agreement) in accordance with the provisions of this Section 4(b) pursuant to written agreements in
form and substance satisfactory to the Holder and approved by the Holder prior to such Fundamental Transaction, such approval not
to be unreasonably withheld, conditioned or delayed, including agreements to 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,
including, without limitation, which is exercisable for a corresponding number of shares of capital stock 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 adjustments to the 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 (ii) the Successor Entity (including its Parent Entity) is a publicly traded corporation whose common stock
is quoted on or listed for trading on an Eligible Market. Upon the consummation of each Fundamental Transaction, the Successor
Entity shall succeed to, and be substituted for (so that from and after the date of the applicable Fundamental Transaction, the
provisions of this Warrant and the other Transaction Documents 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 and the other Transaction Documents with the same effect as if such Successor Entity had been named as the Company
herein. Upon consummation of each Fundamental Transaction, the Successor Entity shall deliver to the Holder confirmation that there
shall be issued upon exercise of this Warrant at any time after the consummation of the applicable Fundamental Transaction, in
lieu of the shares of Common Stock (or other securities, cash, assets or other property (except such items still issuable under
Sections 3 and 4(a) above, which shall continue to be receivable thereafter)) issuable upon the exercise of this Warrant prior
to the applicable Fundamental Transaction, such shares of publicly traded common stock (or its equivalent) of the Successor Entity
(including its Parent Entity) which the Holder would have been entitled to receive upon the happening of the applicable Fundamental
Transaction had this Warrant been exercised immediately prior to the applicable Fundamental Transaction (without regard to any
limitations on the exercise of this Warrant), as adjusted in accordance with the provisions of this Warrant. Notwithstanding the
foregoing, and without limiting Section 1(f) hereof, the Holder may elect, at its sole option, by delivery of written notice to
the Company to waive this Section 4(b) to permit the Fundamental Transaction without the assumption of this Warrant. In addition
to and not in substitution for any other rights hereunder, prior to the consummation of each Fundamental Transaction pursuant to
which holders of shares of Common Stock are entitled to receive securities or other assets with respect to or in exchange for shares
of Common Stock (a “Corporate Event”), the Company shall make appropriate provision to insure that the Holder
will thereafter have the right to receive upon an exercise of this Warrant at any time after the consummation of the applicable
Fundamental Transaction but prior to the Expiration Date, in lieu of the shares of the Common Stock (or other securities, cash,
assets or other property (except such items still issuable under Sections 3 and 4(a) above, which shall continue to be receivable
thereafter)) issuable upon the exercise of the Warrant prior to such Fundamental Transaction, such shares of stock, securities,
cash, assets or any other property whatsoever (including warrants or other purchase or subscription rights) which the Holder would
have been entitled to receive upon the happening of the applicable Fundamental Transaction had this Warrant been exercised immediately
prior to the applicable Fundamental Transaction (without regard to any limitations on the exercise of this Warrant) (collectively,
the “Corporate Event Consideration”). Provision made pursuant to the preceding sentence shall be in a form and
substance reasonably satisfactory to the Holder.

(c)          Black
Scholes Value.


 


(i)          Change
of Control Rights. Notwithstanding the foregoing and the provisions of Section 4(b) above, at the request of the Holder delivered
at any time commencing on the earliest to occur of (A) the public disclosure of any Change of Control, (B) the consummation of
any Change of Control and (C) the Holder first becoming aware of any Change of Control through the date that is ninety (90) days
after the public disclosure of the consummation of such Change of Control by the Company pursuant to a Current Report on Form 8-K
filed with the SEC, the Company or the Successor Entity (as the case may be) shall exchange this Warrant for consideration equal
to the Black Scholes Value of such portion of this Warrant subject to exchange (collectively, the “Aggregate Black Scholes
Value”) in the form of, at the Company’s election (such election to pay in cash or by delivery of the Rights (as
defined below), a “Consideration Election”), either (I) rights (with a beneficial ownership limitation in the
form of Section 1(f)(i) hereof, mutatis mutandis) (collectively, the “Rights”), convertible in whole, or in
part, at any time, without the requirement to pay any additional consideration, at the option of the Holder, into such Corporate
Event Consideration applicable to such Change of Control equal in value to the Aggregate Black Scholes Value (as determined in
accordance with Section 2(b)(iv) above, but with the aggregate number of Successor Shares (as defined below) issuable upon conversion
of the Rights to be determined in increments of 10% of the portion of the Aggregate Black Scholes Value attributable to such Successor
Shares (the “Successor Share Value Increment”), with the aggregate number of Successor Shares issuable upon
exercise of the Rights with respect to the first Successor Share Value Increment determined based on 95% of the Closing Bid Price
of the Successor Shares on the date the Rights are issued and on each of the nine (9) subsequent Trading Days, in each case, the
aggregate number of additional Successor Shares issuable upon exercise of the Rights shall be determined based upon a Successor
Share Value Increment at 95% of the Closing Bid Price of the Successor Shares in effect for such corresponding Trading Day (such
ten (10) Trading Day period commencing on, and including, the date the Rights are issued, the “Rights Measuring Period”),
or (II) in cash; provided, that the Company shall not consummate a Change of Control if (x) the Corporate Event Consideration includes
share capital or other equity interest (the “Successor Shares”) either in an entity that is not listed on an
Eligible Market or an entity in which the daily share volume for the applicable Successor Shares for each of the twenty (20) Trading
Days prior to the date of consummation of such Change of Control is less than the aggregate number of Successor Shares issuable
to the Holder upon conversion in full of the applicable Rights (without regard to any limitations on conversion therein, assuming
the exercise in full of the Rights on the date of issuance of the Rights and assuming the Closing Bid Price of the Successor Shares
for each Trading Day in the Rights Measuring Period is the Closing Bid Price on the Trading Day ended immediately prior to the
time of consummation of the Change of Control) and (y) the Company shall not have properly elected in accordance with this Section
4(c)(i) to pay the applicable Black Scholes Value to the Holder in cash.  The Company shall give the Holder written notice
of each Consideration Election at least twenty (20) Trading Days prior to the time of consummation of such Change of Control. 
Payment of such amounts or delivery of the Rights, as applicable, shall be made by the Company (or at the Company’s direction)
to the Holder on the later of (x) the second (2nd) Trading Day after the date of such request and (y) the date of consummation
of such Change of Control (or, with respect to any Right, if applicable, such later time that holders of shares of Common Stock
are initially entitled to receive Corporate Event Consideration with respect to the shares of Common Stock of such holder). 
Any Corporate Event Consideration included in the Right, if any, pursuant to this Section 4(c)(i) is pari passu with the Corporate
Event Consideration to be paid to holders of shares of Common Stock and the Company shall not permit a payment of any Corporate
Event Consideration to the holders of shares of Common Stock without on or prior to such time delivering the Right to the Holder
hereunder.


 




    	 	16	 



     


    

 


(ii)         Event
of Default Redemption. Notwithstanding the foregoing and the provisions of Section 4(b) above, at the request of the Holder
delivered at any time after the occurrence of an Event of Default (as defined in the Notes)(assuming for such purpose that the
Notes remain outstanding), the Company or the Successor Entity (as the case may be) shall purchase this Warrant from the Holder
on the date of such request by paying to the Holder cash in an amount equal to the Event of Default Black Scholes Value.


 


(d)          Application.
The provisions of this Section 4 shall apply similarly and equally to successive Fundamental Transactions and Corporate Events
and shall be applied as if this Warrant (and any such subsequent warrants) were fully exercisable and without regard to any limitations
on the exercise of this Warrant (provided that the Holder shall continue to be entitled to the benefit of the Maximum Percentage,
applied however with respect to shares of capital stock registered under the 1934 Act and thereafter receivable upon exercise of
this Warrant (or any such other warrant)).


 


5.           NONCIRCUMVENTION.
The Company hereby covenants and agrees that the Company will not, by amendment of its Articles of Incorporation (as defined
in the Securities Purchase Agreement), Bylaws (as defined in the Securities Purchase Agreement) or through any
reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issuance 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, and will at all times in good faith carry out all the provisions of this Warrant and take all action as may be
required to protect the rights of the Holder. Without limiting the generality of the foregoing, the Company (a) shall not
increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price
then in effect, and (b) shall take all such actions as may be necessary or appropriate in order that the Company may validly
and legally issue fully paid and non-assessable shares of Common Stock upon the exercise of this Warrant. Notwithstanding
anything herein to the contrary, if after the sixty (60) calendar day anniversary of the Issuance Date, the Holder is not
permitted to exercise this Warrant in full for any reason (other than pursuant to restrictions set forth in Section 1(f)
hereof), the Company shall use its best efforts to promptly remedy such failure, including, without limitation, obtaining
such consents or approvals as necessary to permit such exercise into shares of Common Stock.


 




    	 	17	 



     


    

 


6.           WARRANT
HOLDER NOT DEEMED A STOCKHOLDER. Except as otherwise specifically provided herein, the Holder, solely in its capacity
as a holder of this Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of share capital of the
Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in its capacity

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

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).

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
