Series A Warrant To Purchase
Common Stock


 


Warrant No.: A-1


 


Date of Issuance: October __, 2020 (“Issuance
Date”)


 


PACIFIC ETHANOL, INC.,
a Delaware corporation (the “Company”), hereby certifies that, for good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, [BUYER], 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 date six (6) months after the date hereof (the “Exercisability Date”),
but not after 11:59 p.m., New York time, on the Expiration Date (as defined below), 8,900,493 (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 19.


 


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 October 26, 2020 (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 Exercisability Date (an
“Exercise Date”), in whole or in part, by delivery (whether via facsimile, electronic mail 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)); provided, however, that upon
thirty (30) days’ prior written notice to the Holder, the Company may elect to require the Holder to make any portion of
such future exercises pursuant to a Cashless Exercise until such time as the Company provides another thirty (30) days’
prior written notice to the Holder requiring the Holder to make any portion of such future exercises on a cash exercise basis,
subject to the provisions of 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 (i) 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 (ii) 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 (A) 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 (B) 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. 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 $9.757, 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, 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 (or prospectus contained therein) 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 (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”), and if
on or after such Share Delivery Date 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 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 (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) as an indemnity for loss hereunder, 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, as an indemnity for loss hereunder, pay cash to the Holder in an amount equal to the excess
(if any) of 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”) 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 resale of the
Warrant Shares that are subject to an Exercise Notice is not available for the resale 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 at the time of exercise hereof a registration statement covering the resale of the Warrant Shares is not effective (or the
prospectus contained therein is not available for use) for the issuance 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)


 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 ten (10) 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) ten (10).


 


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.


 


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.


 






    4


     


    

 


(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 15.


 


(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) 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(f); 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.

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) 
[Intentionally Omitted]


 


(c) 
[Intentionally Omitted]


 


(d) 
Number of Warrant Shares. Simultaneously with any adjustment to the Exercise Price pursuant to this Section 2(a),
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).


 


(e) 
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(d) 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.


 


(f) 
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.


 






    7


     


    

 


(g) 
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 holders of a majority of the SPA Warrants then
outstanding, 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).


 


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).


 






    8


     


    

 


(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 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 referring to the “Company” shall refer instead to the Successor Entity), and may exercise
every right and power of the Company and shall assume all of the obligations of the Company under this Warrant with the same effect
as if such Successor Entity had been named as the Company herein. 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.


 


(c) 
Black Scholes Value. 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.


 


(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, bylaws or other organizational documents 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 one hundred eighty (180) 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.

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

in any securities issued by the Company, may possess and use any information provided by the Company in connection with such trading

11. 
AMENDMENT AND WAIVER. Except as otherwise provided herein, the provisions of this Warrant (other than Section 1(f))
may be amended and the Company may take any action herein prohibited, or omit to perform any act herein required to be performed
by it, only if the Company has obtained the written consent of the Holder. No waiver shall be effective unless it is in writing
and signed by an authorized representative of the waiving party.


 


12. 
SEVERABILITY. If any provision of this Warrant is prohibited by law or otherwise determined to be invalid
or unenforceable by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable
shall be deemed amended to apply to the broadest extent that it would be valid and enforceable, and the invalidity or unenforceability
of such provision shall not affect the validity of the remaining provisions of this Warrant so long as this Warrant as so modified
continues to express, without material change, the original intentions of the parties as to the subject matter hereof and the
prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective
expectations or reciprocal obligations of the parties or the practical realization of the benefits that would otherwise be conferred
upon the parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s)
with a valid provision(s), the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable
provision(s).


 


13. 
GOVERNING LAW. This Warrant shall be governed by and construed and enforced in accordance with, and all questions
concerning the construction, validity, interpretation and performance of this Warrant shall be governed by, the internal laws
of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State
of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State
of New York. The Company hereby irrevocably waives personal service of process and consents to process being served in any such
suit, action or proceeding by mailing a copy thereof to the Company at its principal executive office and agrees that such service
shall constitute good and sufficient service of process and notice thereof. The Company hereby irrevocably submits to the exclusive
jurisdiction of the state and federal courts sitting in The City of New York, Borough of Manhattan, for the adjudication of any
dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably
waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction
of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action
or proceeding is improper. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner
permitted by law. Nothing contained herein shall be deemed or operate to preclude the Holder from bringing suit or taking other
legal action against the Company in any other jurisdiction to collect on the Company’s obligations to the Holder, to realize
on any collateral or any other security for such obligations, or to enforce a judgment or other court ruling in favor of the Holder.
THE COMPANY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE TO, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION
OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS WARRANT OR ANY TRANSACTION CONTEMPLATED HEREBY.
