sufficiency of which are hereby acknowledged, Island Pickle, LLC, 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 Issuance Date,
but not after 11:59 p.m., New York time, on the Expiration Date, (as defined below), Three Hundred Twenty Thousand, Five Hundred
and Thirteen (320,513) fully paid nonassessable shares of Common Stock, subject to adjustment as provided herein (the "Warrant

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 "Supplemental Warrants")

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 at any time or times on or after the Issuance Date, in whole or in part, by
(i) 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 and (ii) (A) payment to the Company of 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(c)). 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 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 fifth (5th) Trading Day following the date
on which the Company has received the Exercise Notice, so long as the Holder delivers the Aggregate Exercise Price (or notice
of a Cashless Exercise) on or prior to the second (2nd) Trading Day following the date on which the Company has received the Exercise
Notice (the "Share Delivery Date") (provided that if the Aggregate Exercise Price has not been delivered by such
date, the Share Delivery Date shall be three (3) Trading Days after the Aggregate Exercise Price (or notice of a Cashless Exercise)
is delivered), the Company shall issue and dispatch by overnight courier to the address as specified in the Exercise Notice, a
certificate, registered in the Company's share register in the name of the Holder or its designee, for the number of Warrant Shares
to which the Holder is entitled pursuant to such exercise. The Company shall be responsible for all fees and expenses of the Transfer
Agent. 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 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 five (5) 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 up 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
any provision of this Warrant to the contrary, no more than the Maximum Eligibility Number of Warrant Shares shall be exercisable
hereunder.

(b)   Exercise
Price. For purposes of this Warrant, "Exercise Price" means $0.78, subject to adjustment as provided herein.


 


(c)   Disputes. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Warrant
Shares, 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.


 


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)   Voluntary Adjustment By Company. 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.


 


(b)   Adjustment Upon Subdivision or Combination of Shares 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.


 


(c)   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 will make an appropriate adjustment in the Exercise Price and the
number of Warrant Shares, 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.           REGISTRATION
RIGHTS. This Warrant shall have piggyback registration rights. The Company hereby agrees to make its best commercial efforts
to include the shares underlying the Warrants in the next available registration statement filed by the Company and is committed
to including the underlying warrant shares in the next available registration statement unless the inclusion of the Warrants in
such a registration statement would cause undue harm to the Company or is prohibited by the securities laws, rules or regulations.


 


4.           NONCIRCUMVENTION.
The Company hereby covenants and agrees that the Company will not, by amendment of its Articles 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 SPA 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 SPA Warrants, 135% of the number of shares of Common Stock as shall from
time to time be necessary to effect the exercise of the SPA Warrants then outstanding (without regard to any limitations on exercise).


 


5.           WARRANT

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 shareholder 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 shareholder 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 shareholders of the Company generally, contemporaneously with the giving thereof to the shareholders.


 


6.           REISSUANCE
OF WARRANTS.


 


(a)   Transfer of Warrant. If this Warrant is to be transferred, the Holder shall surrender this Warrant to the Company, whereupon
the Company will forthwith issue and deliver upon the order of the Holder a new Warrant (in accordance with Section 7(d)), registered

other than the State of California. The Company hereby irrevocably submits to the exclusive jurisdiction of the state and federal
courts sitting in Orange County, California, 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

waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy

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.

case may be, to perform the determinations or calculations and notify the Company and the Holder of the results no later than
ten (10) Business Days from the time it receives the disputed determinations or calculations. Such investment bank's or accountant's
determination or calculation, as the case may be, shall be binding upon all parties absent demonstrable error.

12.         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 other Transaction Documents, 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.


 


13.         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).
