Allarity Therapeutics, Inc. 


 


Warrant To Purchase Common Stock


 


Warrant No.: 2021-1


 


Date of Issuance: December __, 2021 (“Issuance
Date”) 


 


Allarity Therapeutics,
Inc., a Delaware corporation (the “Company”), hereby certifies that, for good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, 3i, LP, the registered holder hereof or its permitted assigns (the “Holder”),
is entitled, subject to the terms set forth below, to purchase from the Company, at the Exercise Price (as defined below) then in effect,
upon exercise of this Warrant to Purchase Common Stock (including any Warrants to Purchase Common Stock issued in exchange, transfer or
replacement hereof, the “Warrant”), at any time or times on or after the Issuance Date, but not after 11:59 p.m., New
York time, on the Expiration Date (as defined below), 2,018,958 (subject to adjustment as provided herein) fully paid and non-assessable
shares of Common Stock (as defined below) (the “Warrant Shares”, and such number of Warrant Shares, the “Warrant
Number”). Except as otherwise defined herein, capitalized terms in this Warrant shall have the meanings set forth in Section 17.
This Warrant is one of the Warrants to Purchase Common Stock (the “SPA Warrants”) issued pursuant to Section 1
of that certain Securities Purchase Agreement, dated as of May 20, 2021 (the “Subscription Date”), by and among the
Company and the investors (the “Buyers”) referred to therein, as amended from time to time (the “Securities
Purchase Agreement”).

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 an
acknowledgment of confirmation of receipt of such Exercise Notice, in the form attached hereto as Exhibit B, to the
Holder and the Company’s transfer agent (the “Transfer Agent”), which confirmation shall constitute an instruction
to 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, upon the request of the Holder, 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, upon the request of the
Holder, 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 a price of $9.9061, subject to further
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, to issue
and deliver to the Holder (or its designee) a certificate for the number of Warrant Shares to which the Holder is entitled and
register such Warrant Shares on the Company’s share register or, if the Transfer Agent is participating in the DTC Fast
Automated Securities Transfer Program, 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 2% 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, 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, 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. While this Warrant
is outstanding, the Company shall cause its transfer agent to participate in the DTC Fast Automated Securities Transfer Program. 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 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 at
the time of exercise hereof a Registration Statement (as defined in the Registration Rights Agreement) is not effective (or the prospectus
contained therein is not available for use) for the resale by the Holder of all of the Warrant Shares, then the Holder may, in its sole
discretion, exercise this Warrant in whole or in part and, 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) 


 B


 


 For purposes of the foregoing
formula:


 


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


 


B = as elected by the Holder: (i) the
VWAP of the shares of 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) at the option of the Holder,
either (y) the VWAP on the Trading Day immediately preceding the date of the applicable Exercise Notice or (z) the Bid Price of the shares
of 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. 


 






    4


     


    

 


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


 


If the Warrant Shares are issued
in a Cashless Exercise, the parties acknowledge and agree that in accordance with Section 3(a)(9) of the 1933 Act, the Warrant Shares
take on the registered characteristics of the Warrants being exercised. 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. 


 


(f)   
Limitations on Exercises. 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


     


    

 


(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 100% 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). 


 


(ii)  Insufficient
Authorized Shares. If, notwithstanding Section 1(g)(i), 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); 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)  shall limit any
obligations of the Company under any provision of the Securities Purchase Agreement.

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), Section 3 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 grants
issues or sells (or enters into any agreement to grant, issue or sell), or in accordance with this Section 2 is deemed to have granted,
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 granted issued or sold or deemed to have been granted 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
granting, issuance or sale or deemed granting 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 adjusted Exercise Price and the New Issuance Price under this Section 2(b)), the following shall be applicable:


  


(i) 
Issuance of Options. If the Company in any manner grants, issues or sells (or enters into any agreement to grant, issue
or sell) 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 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” 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, issuance 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) upon the granting, issuance 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 of or upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange
of such Convertible Securities. 


 






    7


     


    

 


(ii) 
Issuance of Convertible Securities. If the Company in any manner issues or sells (or enters into any agreement to issue
or sell) 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
(or the time of execution of such agreement to issue or sell, as applicable) 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 (or pursuant to the agreement to issue or sell, as applicable) 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) upon the issuance or sale (or the agreement to issue or sell, as applicable)
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 of this Warrant 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. 


 


(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 (including, without limitation, 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. 


 






    8


     


    

 


(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”),
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 difference of (x) the lowest price per share for which one share of Common
Stock was issued (or was deemed to be issued pursuant to Section 2(b)(i) or 2(b)(ii) above, as applicable) in such integrated transaction
solely with respect to such Primary Security, minus (y) with respect to such Secondary Securities, the sum of (I) the Black Scholes Consideration
Value of each such Option, if any, (II) the fair market value (as determined by the Holder in good faith) or the Black Scholes Consideration
Value, as applicable, of such Adjustment Right, if any, and (III) the fair market value (as determined by the Holder) of such Convertible
Security, if any, in each case, as determined on a per share basis in accordance with this Section 2(b)(iv). 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
(for the purpose of determining the consideration paid for such Common Stock, Option or Convertible Security, but not for the purpose
of the calculation of the Black Scholes Consideration Value) 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 (for the purpose of determining the consideration paid for such Common Stock, Option
or Convertible Security, but not for the purpose of the calculation of the Black Scholes Consideration Value) 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
(for the purpose of determining the consideration paid for such Common Stock, Option or Convertible Security, but not for the purpose
of the calculation of the Black Scholes Consideration Value) 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 this Section 2, 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). 


 






    9


     


    

 


(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. 


 






    10


     


    

 


(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. Subject to the rules and regulations of the Principal Market, the Company may at any time
during the term of this Warrant, 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. 


 


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). 


 






    11


     


    

 


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). 


 


(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, 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). Provision made pursuant to the preceding sentence shall be in a form
and substance reasonably satisfactory to the Holder. 


 






    12


     


    

 


(c) 
Black Scholes Value. 


 


(i)  Fundamental Transaction Redemption. 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 (x) the public disclosure of any Fundamental Transaction,
(y) the consummation of any Fundamental Transaction and (z) the Holder first becoming aware of any Fundamental Transaction through the
date that is ninety (90) days after the public disclosure of the consummation of such Fundamental Transaction 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 purchase this Warrant
from the Holder on the date of such request by paying to the Holder cash in an amount equal to the Black Scholes Value. Payment of such
amounts shall be made by the Company (or at the Company’s direction) to the Holder on or prior to the later of (x) the second (2nd)
Trading Day after the date of such request and (y) the date of consummation of such Fundamental Transaction. 


 


(ii) 
Triggering Event 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 Triggering Event (as defined in the Certificate of Designations)(assuming
for such purpose that Preferred Shares 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 Triggering Event 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 Certificate 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. 


 


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 as the Holder
of this Warrant, any of the rights of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action
(whether any reorganization, issue of stock, reclassification of stock, consolidation, merger, conveyance or otherwise), receive notice
of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the Holder of the Warrant Shares which
it is then entitled to receive upon the due exercise of this Warrant. In addition, nothing contained in this Warrant shall be construed
as imposing any liabilities on the Holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a stockholder
of the Company, whether such liabilities are asserted by the Company or by creditors of the Company. Notwithstanding this Section 6,
the Company shall provide the Holder with copies of the same notices and other information given to the stockholders of the Company generally,
contemporaneously with the giving thereof to the stockholders. 





 






    13


     


    

 


7.  REISSUANCE OF WARRANTS. 


 


(a) 
Transfer of Warrant. If this Warrant is to be transferred, the Holder shall surrender this Warrant to the Company, whereupon
the Company will forthwith issue and deliver upon the order of the Holder a new Warrant (in accordance with Section 7(d)), registered
as the Holder may request, representing the right to purchase the number of Warrant Shares being transferred by the Holder and, if less
than the total number of Warrant Shares then underlying this Warrant is being transferred, a new Warrant (in accordance with Section 7(d))
to the Holder representing the right to purchase the number of Warrant Shares not being transferred. 


 


(b) 
Lost, Stolen or Mutilated Warrant. Upon receipt by the Company of evidence reasonably satisfactory to the Company of the
loss, theft, destruction or mutilation of this Warrant (as to which a written certification and the indemnification contemplated below
shall suffice as such evidence), and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to the
Company in customary and reasonable form and, in the case of mutilation, upon surrender and cancellation of this Warrant, the Company
shall execute and deliver to the Holder a new Warrant (in accordance with Section 7(d)) representing the right to purchase the Warrant
Shares then underlying this Warrant. 


 


(c) 
Exchangeable for Multiple Warrants. This Warrant is exchangeable, upon the surrender hereof by the Holder at the principal
office of the Company, for a new Warrant or Warrants (in accordance with Section 7(d)) representing in the aggregate the right to
purchase the number of Warrant Shares then underlying this Warrant, and each such new Warrant will represent the right to purchase such
portion of such Warrant Shares as is designated by the Holder at the time of such surrender; provided, however, no warrants for fractional
shares of Common Stock shall be given. 


 


(d) 
Issuance of New Warrants. Whenever the Company is required to issue a new Warrant pursuant to the terms of this Warrant,
such new Warrant (i) shall be of like tenor with this Warrant, (ii) shall represent, as indicated on the face of such new Warrant, the
right to purchase the Warrant Shares then underlying this Warrant (or in the case of a new Warrant being issued pursuant to Section 7(a)
or Section 7(c), the Warrant Shares designated by the Holder which, when added to the number of shares of Common Stock underlying the
other new Warrants issued in connection with such issuance, does not exceed the number of Warrant Shares then underlying this Warrant),
(iii) shall have an issuance date, as indicated on the face of such new Warrant which is the same as the Issuance Date, and (iv) shall
have the same rights and conditions as this Warrant. 


 






    14


     


    

 


8. NOTICES.
Whenever notice is required to be given under this Warrant, unless otherwise provided herein, such notice shall be given in
accordance with Section 9(f) of the Securities Purchase Agreement. The Company shall provide the Holder with prompt written
notice of all actions taken pursuant to this Warrant (other than the issuance of shares of Common Stock upon exercise in accordance
with the terms hereof), including in reasonable detail a description of such action and the reason therefor. Without limiting the
generality of the foregoing, the Company will give written notice to the Holder (i) immediately upon each adjustment of the Exercise
Price and the number of Warrant Shares, setting forth in reasonable detail, and certifying, the calculation of such adjustment(s),
(ii) at least fifteen (15) days prior to the date on which the Company closes its books or takes a record (A) with respect to any
dividend or distribution upon the shares of Common Stock, (B) with respect to any grants, issuances or sales of any Options,
Convertible Securities or rights to purchase stock, warrants, securities or other property to holders of shares of Common Stock or
(C) for determining rights to vote with respect to any Fundamental Transaction, dissolution or liquidation, provided in each case
that such information shall be made known to the public prior to or in conjunction with such notice being provided to the Holder,
(iii) at least ten (10) Trading Days prior to the consummation of any Fundamental Transaction and (iv) within one (1) Business Day
of the occurrence of an Triggering Event (as defined in the Certificate of Designations), setting forth in reasonable detail any
material events with respect to such Triggering Event and any efforts by the Company to cure such Triggering Event. To the extent
that any notice provided hereunder constitutes, or contains, material, non-public information regarding the Company or any of its
Subsidiaries, the Company shall simultaneously file such notice with the SEC (as defined in the Securities Purchase Agreement)
pursuant to a Current Report on Form 8-K. If the Company or any of its Subsidiaries provides material non-public information to the
Holder that is not simultaneously filed in a Current Report on Form 8-K and the Holder has not agreed to receive such material
non-public information, the Company hereby covenants and agrees that the Holder shall not have any duty of confidentiality to the
Company, any of its Subsidiaries or any of their respective officers, directors, employees, affiliates or agents with respect to, or
a duty to any of the foregoing not to trade on the basis of, such material non-public information. It is expressly understood and
agreed that the time of execution specified by the Holder in each Exercise Notice shall be definitive and may not be disputed or
challenged by the Company. 


 


9. 
DISCLOSURE. Upon delivery by the Company to the Holder (or receipt by the Company from the Holder) of any notice
in accordance with the terms of this Warrant, unless the Company has in good faith determined that the matters relating to such notice
do not constitute material, non-public information relating to the Company or any of its Subsidiaries, the Company shall on or prior to
9:00 am, New York city time on the Business Day immediately following such notice delivery date, publicly disclose such material, non-public
information on a Current Report on Form 8-K or otherwise. In the event that the Company believes that a notice contains material, non-public
information relating to the Company or any of its Subsidiaries, the Company so shall indicate to the Holder explicitly in writing in such
notice (or immediately upon receipt of notice from the Holder, as applicable), and in the absence of any such written indication in such
notice (or notification from the Company immediately upon receipt of notice from the Holder), the Holder shall be entitled to presume
that information contained in the notice does not constitute material, non-public information relating to the Company or any of its Subsidiaries.
Nothing contained in this Section 9 shall limit any obligations of the Company, or any rights of the Holder, under Section [ ] of the
Securities Purchase Agreement. 


 






    15


     


    

 


10. 
ABSENCE OF TRADING AND DISCLOSURE RESTRICTIONS. The Company acknowledges and agrees that the Holder is not a fiduciary or
agent of the Company and that the Holder shall have no obligation to (a) maintain the confidentiality of any information provided by the
Company or (b) refrain from trading any securities while in possession of such information in the absence of a written non-disclosure
agreement signed by an officer of the Holder that explicitly provides for such confidentiality and trading restrictions. In the absence
of such an executed, written non-disclosure agreement, the Company acknowledges that the Holder may freely trade in any securities issued
by the Company, may possess and use any information provided by the Company in connection with such trading activity, and may disclose

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

with its resolution of such dispute (including, without limitation, determining (A) whether an issuance or sale or deemed issuance or
sale of Common Stock occurred under Section 2(b), (B) the consideration per share at which an issuance or deemed issuance of Common Stock

threatened breach, the holder of this Warrant shall be entitled, in addition to all other available remedies, to specific performance
and/or temporary, preliminary and permanent injunctive or other equitable relief from any court of competent jurisdiction in any such
case without the necessity of proving actual damages and without posting a bond or other security. The Company shall provide all information

then during the hour ending at 4:00:00 p.m., New York time) unless such day is otherwise designated as a Trading Day in writing by the
Holder or (y) with respect to all determinations other than price or trading volume determinations relating to the Common Stock, any day
on which The New York Stock Exchange (or any successor thereto) is open for trading of securities. 


 


(ff) 
“Triggering Event Black Scholes Value” means the value of the unexercised portion of this Warrant remaining
on the date of the Holder’s request pursuant to Section 4(c)(ii), which value is calculated using the Black Scholes Option
Pricing Model obtained from the “OV” function on Bloomberg utilizing (i) an underlying price per share equal to the highest
Closing Sale Price of the Common Stock during the period beginning on the date of the occurrence of the Triggering Event through the date
all Events of Default have been cured (assuming for such purpose that the Preferred Shares remain outstanding) or, if earlier, the Trading
Day of the Holder’s request pursuant to Section 4(c)(ii), (ii) a strike price equal to the [Alternate] Exercise Price in effect
on the date of the Holder’s request pursuant to Section 4(c)(ii), (iii) a risk-free interest rate corresponding to the U.S.
Treasury rate for a period equal to the greater of (1) the remaining term of this Warrant as of the date of the Holder’s request
pursuant to Section 4(c)(ii) and (2) the remaining term of this Warrant as of the date of the occurrence of such Triggering Event,
(iv) a zero cost of borrow and (v) an expected volatility equal to the greater of 100% and the 30 day volatility obtained from the “HVT”
function on Bloomberg (determined utilizing a 365 day annualization factor) as of the Trading Day immediately following later of (x) the
date of the occurrence of such Triggering Event and (y) the date of the public announcement of such Triggering Event. 


 


(gg) “VWAP”
means, for any security as of any date, the dollar volume-weighted average price for such security on the Principal Market (or, if the
Principal Market is not the principal trading market for such security, then on the principal securities exchange or securities market
on which such security is then traded), during the period beginning at 9:30 a.m., New York time, and ending at 4:00 p.m., New York time,
as reported by Bloomberg through its “VAP” function (set to 09:30 start time and 16:00 end time) or, if the foregoing does
not apply, the dollar volume-weighted average price of such security in the over-the-counter market on the electronic bulletin board
for such security during the period beginning at 9:30 a.m., New York time, and ending at 4:00 p.m., New York time, as reported by Bloomberg,
or, if no dollar volume-weighted average price is reported for such security by Bloomberg for such hours, the average of the highest
closing bid price and the lowest closing ask price of any of the market makers for such security as reported in The Pink Open Market
(or a similar organization or agency succeeding to its functions of reporting prices). If the VWAP cannot be calculated for such security
on such date on any of the foregoing bases, the VWAP of such security on such date shall be the fair market value as mutually determined
by the Company and the Holder. If the Company and the Holder are unable to agree upon the fair market value of such security, then such
dispute shall be resolved in accordance with the procedures in Section 13. All such determinations shall be appropriately adjusted
for any stock dividend, stock split, stock combination, recapitalization or other similar transaction during such period.
