Marrone
Bio Innovations, Inc., a Delaware corporation (the “Company”), hereby certifies that, for good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, National Securities Corporation, a Washington corporation,
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, at any time or times on or
after the Initial Exercise Date (as defined below), but not after 11:59 p.m., New York time, on the Expiration Date (as defined
below), ______________ (_____________) fully paid nonassessable shares of Common Stock, subject to adjustment as provided herein
(the “Warrant Shares”). Except as otherwise defined herein, capitalized terms in this Warrant to Purchase Common
Stock (including any Warrants to Purchase Common Stock issued in exchange, transfer or replacement hereof, this “Warrant”),
shall have the meanings set forth in Section 17. This Warrant is one of the Warrants to purchase Common Stock (the “NSC

Date”), by and among the Company and National Securities Corporation (the “Engagement Letter”).


 




    	 



     


    




 


1. EXERCISE
OF WARRANT.


 


(a) Mechanics
of Exercise. Subject to the terms and conditions hereof, this Warrant may be exercised by the Holder at any time or times
on or after the Issuance Date, in whole or in part, by delivery of a written notice, in the form attached hereto as Exhibit
A (the “Exercise Notice”), of the Holder’s election to exercise this Warrant. On or prior to the
Trading Day immediately preceding the applicable Share Delivery Date (as defined below), the Holder shall either (A) pay to the
Company an amount equal to the applicable Exercise Price multiplied by the number of Warrant Shares as to which this Warrant is
being exercised (the “Aggregate Exercise Price”) in cash by wire transfer of immediately available funds or
(B) if the provisions of Section 1(d) are applicable, by notifying the Company that this Warrant is being exercised pursuant to
a Cashless Exercise (as defined in Section 1(d)). For the avoidance of doubt, the portion of this Warrant corresponding to the
number of shares referenced in an Exercise Notice shall be deemed exercised upon delivery by the Holder of such Exercise Notice
to the Company. The Holder shall not be required to deliver the original Warrant in order to effect an exercise hereunder. Execution
and delivery of the Exercise Notice with respect to less than all of the Warrant Shares shall have the same effect as cancellation
of the original Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Warrant Shares.
On or before the first (1st) Trading Day following the date on which the Company has received the Exercise Notice,
the Company shall transmit by facsimile or electronic mail an acknowledgment of confirmation of receipt of the Exercise Notice
to the Holder and the Company’s transfer agent (the “Transfer Agent”). On or before the earlier of (i)
the second (2nd) Trading Day and (ii) the number of Trading Days comprising the Standard Settlement Period, in each case, following
the date on which the Holder delivers the Exercise Notice to the Company, so long as the Holder delivers the Aggregate Exercise
Price (or notice of a Cashless Exercise) on or prior to the Trading Day immediately preceding the earlier of clauses (i) and (ii)
above (the “Share Delivery Date”) (provided that if the Aggregate Exercise Price has not been delivered by
such date, the Share Delivery Date shall be one (1) Trading Day after the Aggregate Exercise Price (or notice of a Cashless Exercise)
is delivered), the Company shall (X) provided that the Transfer Agent is participating in The Depository Trust Company (“DTC”)
Fast Automated Securities Transfer Program, credit 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, or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, instruct the
Transfer Agent to issue in book-entry form on the books and records of the Transfer Agent, the number of Warrant Shares to which
the Holder is entitled pursuant to such exercise. The Company shall be responsible for all fees and expenses of the Transfer Agent
and all fees and expenses with respect to the issuance of Warrant Shares via DTC, if any. Upon delivery of the 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, then the Company shall as soon as practicable
and in no event later than three (3) Trading Days after any exercise and at its own expense, issue a new Warrant (in accordance
with Section 7(d)) representing the right to purchase the number of Warrant Shares issuable immediately prior to such exercise
under this Warrant, less the number of Warrant Shares with respect to which this Warrant is exercised. No fractional Warrant Shares
are to be issued upon the exercise of this Warrant, but rather the number of Warrant Shares to be issued shall be rounded to the
nearest whole number. The Company shall pay any and all taxes which may be payable with respect to the issuance and delivery of
Warrant Shares upon exercise of this Warrant. The Company’s obligations to issue and deliver Warrant Shares in accordance
with the terms and subject to the conditions hereof are absolute and unconditional, irrespective of any action or inaction by
the Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against
any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination. Notwithstanding
anything to the contrary herein, except in the case where an exercise of this Warrant is validly made pursuant to a Cashless Exercise
(if permitted), the Company’s failure to deliver Warrant Shares to the Holder shall not be deemed to be a breach of this
Warrant if the Company has not received the Aggregate Exercise Price pursuant to the requirements of this Section 1(a).


 




    	-2-



     


    




 


(b) Initial
Exercise Date and Exercise Price. For purposes of this Warrant, “Initial Exercise Date” refers to the date
that is six (6) months from the Issuance Date and “Exercise Price” means $1.00 per share, 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 to issue to the Holder 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, the number of shares of Common Stock to which the Holder is entitled, in book-entry form on the books and records
of the Transfer Agent, or if the Transfer Agent is participating in the DTC Fast Automated Securities Transfer Program, to credit
the Holder’s balance account with DTC, for such number of shares of Common Stock to which the Holder is entitled upon the
Holder’s exercise of this Warrant or (II) if the Registration Statement (as defined in the Registration Rights Agreement)
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, an “Exercise Failure”), then, in addition to all
other remedies available to the Holder, (X) 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 and (Y) if on or after such Trading Day 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 shares
of Common Stock issuable upon such exercise that the Holder anticipated receiving from the Company (a “Buy-In”),
then the Company shall, within three (3) Trading 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 (the “Buy-In Price”), at
which point the Company’s obligation to instruct the Transfer Agent to register such shares of Common Stock in book-entry
form (and to issue such shares of Common Stock) or credit the Holder’s balance account with DTC for such shares of Common
Stock shall terminate, or (ii) promptly honor its obligation to instruct the Transfer Agent to register such shares of Common
Stock in book-entry form or credit the Holder’s balance account with DTC, as applicable, 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 shares of Common Stock, times (B)
the Closing Sale Price of the Common Stock on the applicable Exercise Date or on the date the Company makes such payment, whichever
is higher. 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.


 




    	-3-



     


    




 


(d) Cashless
Exercise. Notwithstanding anything contained herein to the contrary, if, beginning 180 days after the Issuance Date, the Registration
Statement (as defined in the Registration Rights Agreement) covering the resale of the Unavailable Warrant Shares is not available
for the resale of such Unavailable Warrant Shares, 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 shares of Common Stock
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 arithmetic average of the Closing Sale Prices of the Common Stock for the five (5) consecutive Trading Days ending on
    the date immediately preceding the date of the Exercise Notice.
	 	 
	C	=
    the Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise.
	 	 
	D	=
    the Closing Sale Price of the Common Stock on the date of the Exercise Notice.


 


For
purposes of Rule 144(d) promulgated under the 1933 Act, as in effect on the date hereof, the Company hereby acknowledges and agrees
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 Engagement
Letter.


 




    	-4-



     


    




 


(e) Disputes.
In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the 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 12.


 


(f) Insufficient
Authorized Shares. If at any time while this Warrant remains outstanding the Company does not have a sufficient number of
authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance upon exercise of this Warrant
at least a number of shares of Common Stock equal to the number of shares of Common Stock as shall from time to time be necessary
to effect the exercise of all of this Warrant then outstanding (the “Required Reserve Amount” and the failure
to have such sufficient number of authorized and unreserved shares of Common Stock, an “Authorized Share Failure”),
then the Company shall promptly 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 this Warrant 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 reasonable 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. Notwithstanding the foregoing, if any such time of an Authorized
Share Failure, the Company is able to obtain the written consent of a majority of the shares of its issued and outstanding shares
of Common Stock to approve the increase in the number of authorized shares of Common Stock, the Company may satisfy this obligation
by obtaining such consent and submitting for filing with the SEC an Information Statement on Schedule 14C. In the event that upon
any exercise of this Warrant, the Company does not have sufficient authorized shares to deliver in satisfaction of such exercise,
then unless the Holder elects to void such attempted exercise, the Holder may require the Company to pay to the Holder within
three (3) Trading Days of the applicable exercise, cash in an amount equal to the product of (i) the quotient determined by dividing
(x) the number of Warrant Shares that the Company is unable to deliver pursuant to this Section 1(f), by (y) the total number
of Warrant Shares issuable upon exercise of this Warrant (without regard to any limitations or restrictions on exercise of this
Warrant) and (ii) the Black Scholes Value; provided, that (x) references to “the day immediately following the public announcement
of the applicable Fundamental Transaction” in the definition of “Black Scholes Value” shall instead refer to
“the date the Holder exercises this Warrant and the Company cannot deliver the required number of Warrant Shares because
of an Authorized Share Failure” and (y) clause (iii) of the definition of “Black Scholes Value” shall instead
refer to “the underlying price per share used in such calculation shall be the highest Weighted Average Price during the
period beginning on the date of the applicable date of exercise and the date that the Company makes the applicable cash payment.”

2. ADJUSTMENT
OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The Exercise Price and the number of Warrant Shares shall be adjusted from
time to time as follows:


 


(a) Adjustment
Upon Issuance of Shares of Common Stock. If and whenever on or after the Subscription Date, the Company issues or sells, or
in accordance with this Section 2 is deemed to have issued or sold, any shares of Common Stock (including the issuance or sale
of shares of Common Stock owned or held by or for the account of the Company, but excluding shares of Common Stock deemed to have
been issued or sold by the Company in connection with any Excluded Securities) for a consideration per share (the “New
Issuance Price”) less than a price (the “Applicable Price”) equal to the Exercise Price in effect
immediately prior to such issue or sale or deemed issuance or sale (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 product
of (A) the Exercise Price in effect immediately prior to such Dilutive Issuance and (B) the quotient determined by dividing (1)
the sum of (I) the product derived by multiplying the Exercise Price in effect immediately prior to such Dilutive Issuance and
the number of shares of Common Stock Deemed Outstanding immediately prior to such Dilutive Issuance plus (II) the consideration,
if any, received by the Company upon such Dilutive Issuance, by (2) the product derived by multiplying (I) the Exercise Price
in effect immediately prior to such Dilutive Issuance by (II) the number of shares of Common Stock Deemed Outstanding immediately
after such Dilutive Issuance. For purposes of determining the adjusted Exercise Price under this Section 2(a), the following shall
be applicable:


 


(i) Issuance
of Options. If the Company in any manner grants or sells any Options and the lowest price per share for which one share of
Common Stock is 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 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(a)(i), the “lowest price per share for which one share of Common Stock is 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” shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by
the Company with respect to any one share of Common Stock upon the granting or sale of the Option, upon exercise of the Option
and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise of such Option less any consideration
paid or payable by the Company with respect to such one share of Common Stock upon the granting or sale of such Option, upon exercise
of such Option and upon conversion exercise or exchange of any Convertible Security issuable upon exercise of such Option. No
further adjustment of the Exercise Price or number of Warrant Shares 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 upon the actual issuance of such shares of
Common Stock upon conversion, exercise or exchange of such Convertible Securities.


 




    	-6-



     


    




 


(ii) Issuance
of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities and the lowest price per
share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof is less than the Applicable
Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the
time of the issuance or sale of such Convertible Securities for such price per share. For the purposes of this Section 2(a)(ii),
the “lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof”
shall be equal to 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 issuance or sale of the Convertible Security and upon conversion, exercise or exchange
of such Convertible Security less any consideration paid or payable by the Company with respect to such one share of Common Stock
upon the issuance or sale of such Convertible Security and upon conversion, exercise or exchange of such Convertible Security.
No further adjustment of the Exercise Price or number of Warrant Shares shall be made upon the actual issuance of such shares
of Common Stock upon conversion, exercise or exchange of such Convertible Securities, and if any such issue 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(a), no further adjustment of the Exercise Price or number of Warrant Shares shall be made by reason
of such issue or sale.


 


(iii) Change
in Option Price or Rate of Conversion. If the purchase 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,
the Exercise Price and the number of Warrant Shares in effect at the time of such increase or decrease shall be adjusted to the
Exercise Price and the number of Warrant Shares, 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(a)(iii), if the terms
of any Option or Convertible Security that was outstanding as of the Subscription Date are increased or decreased in the manner
described in the immediately preceding sentence, then such Option or Convertible Security and the shares of Common Stock deemed
issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such increase or
decrease. No adjustment pursuant to this Section 2(a) shall be made if such adjustment would result in an increase of the Exercise
Price then in effect or a decrease in the number of Warrant Shares.


 




    	-7-



     


    




 


(iv) Calculation
of Consideration Received. In case any Option is issued in connection with the issue or sale of other securities of the Company,
together comprising one integrated transaction, (x) the Options will be deemed to have been issued for the Option Value of such
Options and (y) the other securities issued or sold in such integrated transaction shall be deemed to have been issued or sold
for the difference of (I) the aggregate consideration received by the Company less any consideration paid or payable by the Company
pursuant to the terms of such other securities of the Company, less (II) the Option Value. 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 other than cash
received therefor will be deemed to be the net amount received by the Company therefor. If any shares of Common Stock, Options
or Convertible Securities are issued or sold for a consideration other than cash, the amount of such consideration received by
the Company will be the fair value of such consideration, except where such consideration consists of publicly traded securities,
in which case the amount of consideration received by the Company will be the Closing Sale Price of such publicly traded securities
on the date of receipt. If any shares of Common Stock, Options or Convertible Securities are issued to the owners of the non-surviving
entity in connection with any merger in which the Company is the surviving entity, the amount of consideration therefor will be
deemed to be the fair value of such portion of the net assets and business of the non-surviving entity as is attributable to such
shares of Common Stock, Options or Convertible Securities, as the case may be. The fair value of any consideration other than
cash or publicly traded securities will be determined jointly by the Company and the Required Holders. 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) Business Days after the tenth (10th) day following
the Valuation Event by an independent, reputable appraiser jointly selected by the Company and the Required Holders. 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 issue 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.


 


(vi) No
Readjustments. For the avoidance of doubt, in the event the Exercise Price has been adjusted pursuant to this Section 2(a)
and the Dilutive Issuance that triggered such adjustment does not occur, is not consummated, is unwound or is cancelled after
the facts for any reason whatsoever, in no event shall the Exercise Price be readjusted to the Exercise Price that would have
been in effect if such Dilutive Issuance had not occurred or been consummated.


 


(b) Voluntary
Adjustment By Company. Subject to the applicable listing standards 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, 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.


 




    	-8-



     


    




 


(c) Adjustment
Upon Subdivision or Combination of Common Stock. If the Company at any time on or after the Subscription Date subdivides (by
any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock
into a greater number of shares, the Exercise Price in effect immediately prior to such subdivision will be proportionately reduced
and the number of Warrant Shares will be proportionately increased. If the Company at any time on or after the Subscription Date
combines (by combination, reverse stock split or otherwise) one or more classes of its outstanding shares of Common Stock into
a smaller number of shares, the Exercise Price in effect immediately prior to such combination will be proportionately increased
and the number of Warrant Shares will be proportionately decreased. Any adjustment under this Section 2(c) shall become effective
at the close of business on the date the subdivision or combination becomes effective.


 


(d) Other
Events. 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), as mutually determined by the Company’s
Board of Directors and the Required Holders, 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.


 


3. RIGHTS
UPON DISTRIBUTION OF ASSETS. 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 (other than stock or securities in which an adjustment is being made pursuant
to Section 2(c)), 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, upon the exercise of this Warrant, in whole or
in part, be entitled to receive such Distribution to the same extent that the Holder would have received 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) immediately before the date of 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. From the time of any Distribution until this Warrant is exercised or expires, the Company shall hold such Distribution
for the benefit of the Holder and distribute such Distribution to the Holder on the applicable Share Delivery Date with respect
to the portion of this Warrant being exercised.


 


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) 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, issue or sale of such Purchase Rights.


 




    	-9-



     


    




 


(b) Fundamental
Transactions. The Company shall not enter into or be party to a Fundamental Transaction unless the Successor Entity assumes
in writing all of the obligations of the Company under this Warrant and the Engagement Letter in accordance with the provisions
of this Section 4(b) pursuant to written agreements in form and substance satisfactory to the Required Holders prior to such Fundamental
Transaction, including agreements, if so requested by the Holder, to deliver to each holder of the NSC Warrants in exchange for
such NSC Warrants 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 reasonably satisfactory to the Required Holders, 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 occurrence or consummation of such Fundamental Transaction). Upon the occurrence
or consummation of any Fundamental Transaction, and it shall be a required condition to the occurrence or consummation of any
Fundamental Transaction that, the Company and the Successor Entity or Successor Entities, jointly and severally, shall succeed
to, and the Company shall cause any Successor Entity or Successor Entities to jointly and severally succeed to, and be added to
the term “Company” under this Warrant (so that from and after the date of such Fundamental Transaction, each and every
provision of this Warrant referring to the “Company” shall refer instead to each of the Company and the Successor
Entity or Successor Entities, jointly and severally), and the Company and the Successor Entity or Successor Entities, jointly
and severally, may exercise every right and power of the Company prior thereto and shall assume all of the obligations of the
Company prior thereto under this Warrant with the same effect as if the Company and such Successor Entity or Successor Entities,
jointly and severally, had been named as the Company in this Warrant. Upon occurrence or consummation of the Fundamental Transaction,
and it shall be a required condition to the occurrence or consummation of such Fundamental Transaction that, the Company and the
Successor Entity or Successor Entities shall deliver to the Holder confirmation that there shall be issued upon exercise of this
Warrant at any time after the occurrence or consummation of the Fundamental Transaction, as elected by the Holder solely at its
option, shares of Common Stock or shares of capital stock of the Successor Entity and/or Successor Entities (the “Successor
Capital Stock”) or, in lieu of the shares of Common Stock or Successor Capital Stock (or other securities, cash, assets
or other property purchasable upon the exercise of this 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
for purposes of clarification may continue to be shares of Common Stock, if any, that the Holder would have been entitled to receive
upon the happening of such Fundamental Transaction or the record, eligibility or other determination date for the event resulting
in such Fundamental Transaction, had this Warrant been exercised immediately prior to such Fundamental Transaction or the record,
eligibility or other determination date for the event resulting in such 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,
(i) the Holder may elect, at its sole option, by delivery of written notice to the Company to waive this Section 4(b) in writing
to permit the Fundamental Transaction without redemption, similar repayment, “cash out” or assumption of this Warrant
(as applicable) and (ii) if holders of Common Stock are given any choice as to the securities, cash or other assets to be received
in a Fundamental Transaction, then the Holder shall be given the same choice as the consideration it receives upon any exercise
of this Warrant following a Corporate Event. In addition to and not in substitution for any other rights hereunder, prior to the
occurrence or consummation of any Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to
receive securities, cash, assets or other property with respect to or in exchange for shares of Common Stock (a “Corporate
Event”), the Company shall make appropriate provision to ensure that, and any applicable Successor Entity or Successor
Entities shall ensure that, and it shall be a required condition to the occurrence or consummation of such Corporate Event that,
the Holder will thereafter have the right to receive upon exercise of this Warrant at any time after the occurrence or consummation
of the Corporate Event, shares of Common Stock or Successor Capital Stock or, if so elected by the Holder, in lieu of the shares
of Common Stock or Successor Capital Stock (or other securities, cash, assets or other property) purchasable upon the exercise
of this Warrant prior to such Corporate Event (but not in lieu of such items still issuable under Sections 3 and 4(a), which shall
continue to be receivable on the shares of Common Stock or on the such shares of stock, securities, cash, assets or any other
property otherwise receivable with respect to or in exchange for shares of Common Stock), such shares of stock, securities, cash,
assets or any other property whatsoever (including warrants or other purchase or subscription rights and any shares of Common
Stock) which the Holder would have been entitled to receive upon the occurrence or consummation of such Corporate Event or the
record, eligibility or other determination date for the event resulting in such Corporate Event, had this Warrant been exercised
immediately prior to such Corporate Event or the record, eligibility or other determination date for the event resulting in such
Corporate Event (without regard to any limitations on exercise of this Warrant). Provision made pursuant to the preceding sentence
shall be in a form and substance reasonably satisfactory to the Holder. The provisions of this Section 4(b) shall apply similarly
and equally to successive Fundamental Transactions and Corporate Events. Notwithstanding, anything herein to the contrary, if
a Corporate Event occurs where the holders of shares of Common Stock receive cash and/or securities listed on an Eligible Market,
this Warrant shall no longer be exercisable for shares of Common Stock or Successor Capital Stock (but such items issuable under
Sections 3 and 4(a) shall continue to be receivable).

(c) Notwithstanding
the foregoing, in the event of a Fundamental Transaction other than one in which a Successor Entity that is a publicly traded
corporation whose stock is quoted or listed for trading on an Eligible Market assumes this Warrant such that the Warrant shall
be exercisable for the publicly traded Common Stock of such Successor Entity, at the request of the Holder delivered before the
ninetieth (90th) day after the occurrence or consummation of such Fundamental Transaction, the Company (or the Successor
Entity) shall purchase this Warrant from the Holder by paying to the Holder, within five (5) Business Days after such request
(or, if later, on the effective date of the Fundamental Transaction), cash in an amount equal to the Black Scholes Value of the
remaining unexercised portion of this Warrant on the date of such Fundamental Transaction.


 


5. NONCIRCUMVENTION.
The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation or Bylaws,
or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue 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 of 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 (i) 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, (ii)
shall take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid
and nonassessable shares of Common Stock upon the exercise of this Warrant, and (iii) shall, so long as any of the NSC Warrants
are outstanding, take all action necessary to reserve and keep available out of its authorized and unissued shares of Common Stock,
solely for the purpose of effecting the exercise of the NSC Warrants, the number of shares of Common Stock as shall from time
to time be necessary to effect the exercise of the NSC Warrants then outstanding (without regard to any limitations on exercise).


 


6. WARRANT
HOLDER NOT DEEMED A STOCKHOLDER. Except as otherwise specifically provided herein, the Holder, solely in such Person’s
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
such Person’s 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 such Person 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; provided, that the Company shall not be required to provide the Holder with such
notices and other information to the extent such notices or other information is filed with the SEC pursuant to its Electronic
Data Gathering, Analysis and Retrieval (EDGAR) system.


 


7. REISSUANCE
OF WARRANTS.


 


(a) Transfer

9. AMENDMENT

LAW; JURISDICTION; JURY TRIAL. 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 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

personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof
to the Company at the address set forth in Section 8 hereof and agrees that such service shall constitute good and sufficient
service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process

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, 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.


 


11. CONSTRUCTION;
HEADINGS. This Warrant shall be deemed to be jointly drafted by the Company and all the Buyers and shall not be construed

Holder and the Company are unable to agree upon such determination or calculation of the Exercise Price or the Warrant Shares
within three (3) Business Days of such disputed determination or arithmetic calculation being submitted to the Holder, then the
Company shall, within two (2) Business Days submit via facsimile or electronic mail (a) the disputed determination of the Exercise

13. REMEDIES,
OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF. The remedies provided in this Warrant shall be cumulative and in addition
to all other remedies available under this Warrant and the Engagement Letter, at law or in equity (including a decree of specific
performance and/or other injunctive relief), and nothing herein shall limit the right of the Holder to pursue actual damages for
any failure by the Company to comply with the terms of this Warrant. The Company acknowledges that a breach by it of its obligations
hereunder will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company
therefore agrees that, in the event of any such breach or threatened breach, the holder of this Warrant shall be entitled, in
addition to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss
and without any bond or other security being required.

15. 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).


 


16. DISCLOSURE.
Upon receipt or delivery by the Company 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, nonpublic information relating to the
Company or its Subsidiaries, the Company shall within four (4) Business Days after any such receipt or delivery publicly disclose
such material, nonpublic information on a Current Report on Form 8-K or otherwise. In the event that the Company believes that
a notice contains material, nonpublic information relating to the Company or its Subsidiaries, the Company so shall indicate to
the Holder contemporaneously with delivery of such notice, and in the absence of any such indication, the Holder shall be allowed
to presume that all matters relating to such notice do not constitute material, nonpublic information relating to the Company
or its Subsidiaries.
