Warrant No.: 0914Fee-1

Number of Shares of Common Stock: 250,000

Date of Issuance: September 29, 2014 ("Issuance Date")

Ener-Core, Inc., a
Nevada corporation (the "Company"), hereby certifies that, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, Chardan capital markets, 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), Two Hundred Fifty Thousand
(250,000) 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 14. This Warrant is one of the Warrants to purchase Common Stock issued pursuant to the Placement

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(c) 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 affect an exercise hereunder, provided,
however, that the Holder shall covenant in the Exercise Notice, that it will deliver the original Warrant to the Company within
three (3) Trading Days of its delivery of its Exercise Notice. 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 each of the Exercise Notice and, if this Warrant is being exercised pursuant to a Cash
Exercise, the Aggregate Exercise Price (the “Exercise Delivery Documents”), the Company shall transmit by facsimile
or email 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 Delivery Documents, 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 Delivery Documents
(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 Delivery Documents and surrender of this Warrant, 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 5(e)) 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 down
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, provided, however, that the Company
shall not be required to pay any tax which may be payable based on the income of the Holder or in respect of any transfer involved
in the registration of any certificates for Warrant Shares or Warrants in a name other than that of the Holder or an Affiliate
thereof.

(b)         Exercise
Price. For purposes of this Warrant, "Exercise Price" means $0.50, subject to adjustment as provided herein.

 

(c)         Cashless
Exercise.  Notwithstanding anything contained herein to the contrary, if there is no effective registration statement
registering, or no current prospectus available for the resale 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 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 Securities Act, as in effect on the date hereof, it is intended, understood and acknowledged 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. 

(d)         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 8.

(e)         Compliance with Securities Laws.

(i)The Holder
of this Warrant, by acceptance hereof, acknowledges that this Warrant and the Common Stock to be issued upon exercise hereof are
being acquired solely for the Holder’s own account and not as a nominee for any other party; and for investment, and that
the Holder will not offer, sell or otherwise dispose of this Warrant or any Common Stock to be issued upon exercise hereof except
under circumstances that will not result in a violation of the Securities Act or any state securities laws. Upon exercise of this
Warrant, the Holder shall, if requested by the Company, confirm in writing, in a form satisfactory to the Company, that the Common
Stock so purchased are being acquired solely for the Holder's own account and not as a nominee for any other party, for investment,
and not with a view toward distribution or resale.

(ii)This Warrant
and all Common Stock issued upon exercise hereof unless registered under the Securities Act shall be stamped or imprinted with
a legend in substantially the following form (in addition to any legend required by state securities laws):

THE SECURITIES
REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND
MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF REGULATION S PROMULGATED
UNDER THE SECURITIES ACT, PURSUANT TO REGISTRATION UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM REGISTRATION.
HEDGING TRANSACTIONS INVOLVING THE SECURITIES REPRESENTED HEREBY MAY NOT BE CONDUCTED UNLESS IN COMPLIANCE WITH THE SECURITIES
ACT. THIS CERTIFICATE MUST BE SURRENDERED TO THE COMPANY OR ITS TRANSFER AGENT AS A CONDITION PRECEDENT TO THE SALE, PLEDGE, HYPOTHECATION
OR ANY OTHER TRANSFER OF ANY INTEREST IN ANY OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE.

(f)          Limitations on Exercise. The Company shall not effect the exercise of this Warrant, and the Holder shall not have
the right to exercise this Warrant, to the extent that after giving effect to such exercise, such Person (together with such Person’s
Affiliates) would beneficially own in excess of 9.99% (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 such Person and its Affiliates shall include 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 (i) exercise of the remaining, unexercised portion of this Warrant beneficially
owned by such Person and its Affiliates and (ii) exercise or conversion of the unexercised or unconverted portion of any other
securities of the Company beneficially owned by such Person and its Affiliates (including, without limitation, any convertible
notes or convertible preferred stock or warrants) subject to a limitation on conversion or exercise analogous to the limitation
contained herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be
calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).
For purposes of this Warrant, in determining the number of outstanding shares of Common Stock, the Holder may rely on the number
of outstanding shares of Common Stock as reflected in (1) the Company’s most recent Form 10-K, Form 10-Q, Current Report
on Form 8-K or other public filing with the Securities and Exchange Commission, as the case may be, (2) a more recent public
announcement by the Company or (3) any other notice by the Company or the Transfer Agent setting forth the number of shares
of Common Stock outstanding. For any reason at any time, upon the written or oral request of the Holder, the Company shall within
two (2) Trading Days confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In
any case, the number of outstanding shares Common Stock shall be determined after giving effect to the conversion or exercise of
securities of the Company, including the Warrants, by the Holder and its Affiliates since the date as of which such number of outstanding
shares of Common Stock was reported. This restriction may not be waived. Notwithstanding anything to the contrary contained in
this Warrant, (a) no term of this Section may be waived by any party, nor amended such that the threshold percentage of ownership
would be directly or indirectly increased, (b) this restriction runs with the Warrant and may not be modified or waived by any
subsequent holder hereof and (c) any attempted waiver, modification or amendment of this Section will be void ab initio.

    	- 4 -

    	 

    

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 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
Issuance 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 Issuance 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(b) 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 Section 2(b) 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 so as to protect the rights of the Holder; provided that no such adjustment pursuant to this
Section 2(c) will increase the Exercise Price or decrease the number of Warrant Shares as otherwise determined pursuant to this
Section 2.

3.          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 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 Warrants, the number of shares of Common Stock
as shall from time to time be necessary to effect the exercise of the Warrants then outstanding (without regard to any limitations
on exercise).

4.           WARRANT
HOLDER NOT DEEMED A SHAREHOLDER. 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 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.

5.           REISSUANCE
OF WARRANTS.

for that purpose (the “Warrant Register”), in the name of the record Holder hereof from time to time. The Company

of the loss, theft, destruction or mutilation of this Warrant, and, in the case of loss, theft or destruction, of any indemnification
undertaking by the Holder to the Company in customary form and, in the case of mutilation, upon surrender and cancellation of this

8.           GOVERNING
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 California, without giving effect to any choice of law or conflict of law provision or rule (whether of the State
of California or any other jurisdictions) that would cause the application of the laws of any jurisdictions 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 or proceeding (“Proceedings”),
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. 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 the address set forth herein 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 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. If either party
shall commence a Proceeding in connection with or related to this Warrant or any transaction contemplated hereby or discussed
herein, then the prevailing party in such Proceeding shall be reimbursed by the other party for its attorney’s fees and
other costs and expenses incurred with the investigation, preparation and prosecution of such Proceeding.

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

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, 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.

11.         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).

of this Warrant and shall not be deemed to limit or affect any of the provisions hereof.

hereby shall inure to the benefit of and be binding upon the successors of the Company and the successors and permitted assigns

Warrant
To Purchase Common Stock

 

Warrant No.: 0914Fee-2

Number of Shares of Common Stock: 750,000

Date of Issuance: September 29, 2014 ("Issuance Date")

 

Ener-Core, Inc., a
Nevada corporation (the "Company"), hereby certifies that, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, THE SPECIAL EQUITIES GROUP, 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), Seven Hundred Fifty Thousand
(750,000) 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 14. This Warrant is one of the Warrants to purchase Common Stock issued pursuant to the Placement
Agent Agreement, dated as of September 9, 2014, and approved by the Company’s Board of Directors on September 29, 2014, by
and among the Company and Chardan Capital Markets, LLC referred to therein (the "Services Agreement"). Capitalized
terms used herein and not otherwise defined shall have the definitions ascribed to such terms in the Services 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 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(c) 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 affect an exercise hereunder, provided, however,
that the Holder shall covenant in the Exercise Notice, that it will deliver the original Warrant to the Company within three (3)
Trading Days of its delivery of its Exercise Notice. 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 each of the Exercise Notice and, if this Warrant is being exercised pursuant to a Cash Exercise,
the Aggregate Exercise Price (the “Exercise Delivery Documents”), the Company shall transmit by facsimile or
email 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 Delivery
Documents, 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 Delivery Documents (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
Delivery Documents and surrender of this Warrant, 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 5(e)) 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 down 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, provided, however, that the Company shall not be required to pay any tax which
may be payable based on the income of the Holder or in respect of any transfer involved in the registration of any certificates
for Warrant Shares or Warrants in a name other than that of the Holder or an Affiliate thereof.

          (b)      Exercise
Price. For purposes of this Warrant, "Exercise Price" means $0.50, subject to adjustment as provided herein.

 

          (c)      Cashless
Exercise.  Notwithstanding anything contained herein to the contrary, if there is no effective registration statement
registering, or no current prospectus available for the resale 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 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 Securities Act, as in effect on the date hereof, it is intended, understood and acknowledged 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.

 

          (d)     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 8.

 

          (e)     Compliance
with Securities Laws.

 

                   (i)The Holder
of this Warrant, by acceptance hereof, acknowledges that this Warrant and the Common Stock to be issued upon exercise hereof are
being acquired solely for the Holder’s own account and not as a nominee for any other party; and for investment, and that
the Holder will not offer, sell or otherwise dispose of this Warrant or any Common Stock to be issued upon exercise hereof except
under circumstances that will not result in a violation of the Securities Act or any state securities laws. Upon exercise of this
Warrant, the Holder shall, if requested by the Company, confirm in writing, in a form satisfactory to the Company, that the Common
Stock so purchased are being acquired solely for the Holder's own account and not as a nominee for any other party, for investment,
and not with a view toward distribution or resale.

 

    	3

    	 

    

 

 

                 (ii)This Warrant
and all Common Stock issued upon exercise hereof unless registered under the Securities Act shall be stamped or imprinted with
a legend in substantially the following form (in addition to any legend required by state securities laws):

 

THE SECURITIES
REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND
MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF REGULATION S PROMULGATED
UNDER THE SECURITIES ACT, PURSUANT TO REGISTRATION UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM REGISTRATION.
HEDGING TRANSACTIONS INVOLVING THE SECURITIES REPRESENTED HEREBY MAY NOT BE CONDUCTED UNLESS IN COMPLIANCE WITH THE SECURITIES
ACT. THIS CERTIFICATE MUST BE SURRENDERED TO THE COMPANY OR ITS TRANSFER AGENT AS A CONDITION PRECEDENT TO THE SALE, PLEDGE, HYPOTHECATION
OR ANY OTHER TRANSFER OF ANY INTEREST IN ANY OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE.

 

          (f)      Limitations
on Exercise. The Company shall not effect the exercise of this Warrant, and the Holder shall not have the right to exercise
this Warrant, to the extent that after giving effect to such exercise, such Person (together with such Person’s Affiliates)
would beneficially own in excess of 9.99% (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 such Person and its Affiliates shall include 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 (i) exercise of the remaining, unexercised portion of this Warrant beneficially owned by such
Person and its Affiliates and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities
of the Company beneficially owned by such Person and its Affiliates (including, without limitation, any convertible notes or convertible
preferred stock or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except
as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance
with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). For purposes
of this Warrant, in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding
shares of Common Stock as reflected in (1) the Company’s most recent Form 10-K, Form 10-Q, Current Report on Form 8-K
or other public filing with the Securities and Exchange Commission, as the case may be, (2) a more recent public announcement
by the Company or (3) any other notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock
outstanding. For any reason at any time, upon the written or oral request of the Holder, the Company shall within two (2) Trading
Days confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number
of outstanding shares Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company,
including the Warrants, by the Holder and its Affiliates since the date as of which such number of outstanding shares of Common
Stock was reported. This restriction may not be waived. Notwithstanding anything to the contrary contained in this Warrant, (a)
no term of this Section may be waived by any party, nor amended such that the threshold percentage of ownership would be directly
or indirectly increased, (b) this restriction runs with the Warrant and may not be modified or waived by any subsequent holder
hereof and (c) any attempted waiver, modification or amendment of this Section will be void ab initio.

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 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 Issuance 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 Issuance 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(b) 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 Section 2(b) 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 so as to protect the rights of the Holder; provided that no such adjustment pursuant to this Section
2(c) will increase the Exercise Price or decrease the number of Warrant Shares as otherwise determined pursuant to this Section
2.

 

    	5

    	 

    

 

 

3.       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 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 Warrants, the number of shares of Common Stock as shall from time to time be necessary
to effect the exercise of the Warrants then outstanding (without regard to any limitations on exercise).

 

4.       WARRANT
HOLDER NOT DEEMED A SHAREHOLDER. 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 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.

 

5.       REISSUANCE
OF WARRANTS.

 

          (a)      Registration
of Warrant. The Company shall register this Warrant, upon the records to be maintained by the Company for that purpose (the
“Warrant Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat
the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution
to the Holder, and for all other purposes, absent actual notice to the contrary. The Company shall also register any transfer,
exchange, reissuance or cancellation of any portion of this Warrant in the Warrant Register.

 

          (b)      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 5(e)), registered as the
Holder may request, representing the right to purchase the number of Warrant Shares being transferred by the Holder and, if less
than the total number of Warrant Shares then underlying this Warrant is being transferred, a new Warrant (in accordance with Section
5(e)) to the Holder representing the right to purchase the number of Warrant Shares not being transferred.

 

    	6

    	 

    

 

          (c)      Lost,
Stolen or Mutilated Warrant. Upon receipt by the Company of evidence reasonably satisfactory to the Company of the loss, theft,
destruction or mutilation of this Warrant, and, in the case of loss, theft or destruction, of any indemnification undertaking
by the Holder to the Company in customary form and, in the case of mutilation, upon surrender and cancellation of this Warrant,
the Company shall execute and deliver to the Holder a new Warrant (in accordance with Section 5(e)) representing the right to
purchase the Warrant Shares then underlying this Warrant.

 

          (d)      Exchangeable
for Multiple Warrants. This Warrant is exchangeable, upon the surrender hereof by the Holder at the principal office of the
Company, for a new Warrant or Warrants (in accordance with Section 5(e)) representing in the aggregate the right to purchase the
number of Warrant Shares then underlying this Warrant, and each such new Warrant will represent the right to purchase such portion
of such Warrant Shares as is designated by the Holder at the time of such surrender; provided, however, that no
Warrants for fractional Warrant Shares shall be given.

 

          (e)      Issuance

the other new Warrants issued in connection with such issuance, does not exceed the number of Warrant Shares then underlying this
Warrant), (iii) shall have an issuance date, as indicated on the face of such new Warrant which is the same as the Issuance Date,
and (iv) shall have the same rights and conditions as this Warrant.

    	7

    	 

    

 

8.       GOVERNING
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 California, without giving effect to any choice of law or conflict of law provision or rule (whether of the State
of California or any other jurisdictions) that would cause the application of the laws of any jurisdictions 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 or proceeding (“Proceedings”),
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. 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 the address set forth herein 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 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. If either party
shall commence a Proceeding in connection with or related to this Warrant or any transaction contemplated hereby or discussed
herein, then the prevailing party in such Proceeding shall be reimbursed by the other party for its attorney’s fees and
other costs and expenses incurred with the investigation, preparation and prosecution of such Proceeding.

 

9.       CONSTRUCTION;
HEADINGS. This Warrant shall be deemed to be jointly drafted by the Company and all the Buyers and shall not be construed
against any Person as the drafter hereof. The headings of this Warrant are for convenience of reference and shall not form part
of, or affect the interpretation of, this Warrant.

 

10.     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, 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.

 

    	8

    	 

    

 

11.     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).

 

12.     CONSTRUCTION
AND HEADINGS. This Warrant shall be deemed to be jointly drafted by the Company and the Holder and shall not be construed
against any person as the drafter hereof. The headings herein are for convenience only, do not constitute a part of this Warrant
and shall not be deemed to limit or affect any of the provisions hereof.

 

13.     SUCCESSORS

to the benefit of and be binding upon the successors of the Company and the successors and permitted assigns of Holder. The provisions

any such Holder.
