attached Warrant Shares Exercise Log) at its address for notice set forth herein and upon payment of the Exercise Price multiplied
by the number of Warrant Shares that the Holder intends to purchase hereunder, the Company shall promptly (but in no event later
than three Trading Days after the Date of Exercise (as defined herein)) issue and deliver to the Holder, a certificate for the
Warrant Shares issuable upon such exercise. The Company shall, upon request of the Holder and subsequent to the date on which a
registration statement covering the resale of the Warrant Shares has been declared effective by the Securities and Exchange Commission,
use its reasonable best efforts to deliver Warrant Shares hereunder electronically through the Depository Trust & Clearing

    	-3-

    	 

    

 

(b)If by the third
Trading Day after a Date of Exercise the Company fails to deliver the required number of Warrant Shares in the manner required
pursuant to Section 5(a), then the Holder will have the right to rescind such exercise.

 

(c)At any time following
the earlier of (i) the fifth day following the effective date of the registration statement filed by the Company registering the
resale of the Warrant Shares and (ii) the one year anniversary of the Original Issue Date, if by the fifth Trading Day after a
Date of Exercise the Company fails to deliver the required number of Warrant Shares in the manner required pursuant to Section
5(a), and if after such fifth Trading Day and prior to the receipt of such Warrant Shares, 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 the Warrant Shares which
the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall (1) pay in cash to
the Holder the amount by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for the shares
of Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the number of Warrant Shares that the Company was
required to deliver to the Holder in connection with the exercise at issue by (B) the closing bid price of the Common Stock on
the Date of Exercise and (2) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of
Warrant Shares for which such exercise was not honored or deliver to the Holder the number of shares of Common Stock that would
have been issued had the Company timely complied with its exercise and delivery obligations hereunder. The Holder shall provide
the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In.

 

(d)The Company’s
obligations to issue and deliver Warrant Shares in accordance with the terms 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,
or any breach or alleged breach by the Holder or any other Person of any obligation to the Company or any violation or alleged
violation of law by the Holder or any other Person, and irrespective of any other circumstance which might otherwise limit such
obligation of the Company to the Holder in connection with the issuance of Warrant Shares. Nothing herein shall limit a 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 Warrant
Shares upon exercise of the Warrant as required pursuant to the terms hereof.

 

6.Charges, Taxes
and Expenses. Issuance and delivery of Warrant Shares upon exercise of this Warrant shall be made without charge to the Holder
for any issue or transfer tax, withholding tax, transfer agent fee or other incidental tax or expense in respect of the issuance
of such certificates, all of which taxes and expenses shall be paid by the Company; provided, however, that the Company shall not
be required to pay any tax which may be payable 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. The Holder shall be responsible for all other tax liability
that may arise as a result of holding or transferring this Warrant or receiving Warrant Shares upon exercise hereof.

 

    	-4-

    	 

    

 

7.Replacement
of Warrant. If this Warrant is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange
and substitution for and upon cancellation hereof, or in lieu of and substitution for this Warrant, a New Warrant, but only upon
receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and customary and reasonable indemnity
(which shall not include a surety bond), if requested. Applicants for a New Warrant under such circumstances shall also comply
with such other reasonable regulations and procedures and pay such other reasonable third-party costs as the Company may prescribe.
If a New Warrant is requested as a result of a mutilation of this Warrant, then the Holder shall deliver such mutilated Warrant
to the Company as a condition precedent to the Company’s obligation to issue the New Warrant.

 

8.Reservation
of Warrant Shares. The Company covenants that it will at all times reserve and keep available out of the aggregate of its authorized
but unissued and otherwise unreserved Common Stock, solely for the purpose of enabling it to issue Warrant Shares upon exercise
of this Warrant as herein provided, the number of Warrant Shares which are then issuable and deliverable upon the exercise of this
entire Warrant, free from preemptive rights or any other contingent purchase rights of Persons other than the Holder (taking into
account the adjustments and restrictions of Section 9). The Company covenants that all Warrant Shares so issuable and deliverable
shall, upon issuance and the payment of the applicable Exercise Price in accordance with the terms hereof, be duly and validly
authorized, issued and fully paid and nonassessable.

 

9.Certain Adjustments.
The Exercise Price and number of Warrant Shares issuable upon exercise of this Warrant are subject to adjustment from time to time
as set forth in this Section 9.

 

(a)Stock Dividends
and Splits. If the Company, at any time while this Warrant is outstanding, (i) pays a stock dividend on its Common Stock or
otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides outstanding
shares of Common Stock into a larger number of shares, or (iii) combines outstanding shares of Common Stock into a smaller
number of shares, then in each such case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the
number of shares of Common Stock outstanding immediately before such event and of which the denominator shall be the number of
shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to clause (i) of this paragraph shall
become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution,
and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective immediately after the effective date
of such subdivision or combination.

 

(b)Fundamental
Transactions. If, at any time while this Warrant is outstanding there is a Fundamental Transaction, then the Holder shall have
the right thereafter to receive, upon exercise of this Warrant, the same amount and kind of securities, cash or property as it
would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such
Fundamental Transaction, the holder of the number of Warrant Shares then issuable upon exercise in full of this Warrant (the “Alternate
Consideration”). For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted
to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common
Stock in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in
a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common
Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder
shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental
Transaction. The Company shall use its reasonable best efforts to ensure that at the Holder’s option and request, any successor
to the Company or surviving entity in such Fundamental Transaction shall issue to the Holder a new warrant substantially in the
form of this Warrant and consistent with the foregoing provisions and evidencing the Holder’s right to purchase the Alternate
Consideration for the aggregate Exercise Price upon exercise thereof. The Company shall use its reasonable best efforts to ensure
that the terms of any agreement pursuant to which a Fundamental Transaction is effected shall include terms requiring any such
successor or surviving entity to comply with the provisions of this paragraph (b) and ensuring that the Warrant (or any such replacement
security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction.

 

    	-5-

    	 

    

 

(c)Number of Warrant
Shares. Simultaneously with any adjustment to the Exercise Price pursuant to this Section 9, the number of Warrant Shares that
may be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that after such adjustment the
aggregate Exercise Price payable hereunder for the adjusted number of Warrant Shares shall be the same as the aggregate Exercise
Price in effect immediately prior to such adjustment.

 

(d)Calculations.
All calculations under this Section 9 shall be made to the nearest cent or the nearest 1/100th of a share, as applicable.
The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account
of the Company, and the disposition of any such shares shall be considered an issue or sale of Common Stock.

 

(e)Notice of Adjustments.
Upon the occurrence of each adjustment pursuant to this Section 9, the Company at its expense will promptly compute such adjustment
in accordance with the terms of this Warrant and prepare a certificate setting forth such adjustment, including a statement of
the adjusted Exercise Price and adjusted number or type of Warrant Shares or other securities issuable upon exercise of this Warrant
(as applicable), describing the transactions giving rise to such adjustments and showing in detail the facts upon which such adjustment
is based. Upon written request, the Company will promptly deliver a copy of each such certificate to the Holder and to the Company’s
Transfer Agent.

 

(f)Notice of Corporate
Events. If the Company (i) declares a dividend or any other distribution of cash, securities or other property in respect of
its Common Stock, including without limitation any granting of rights or warrants to subscribe for or purchase any capital stock
of the Company or any Subsidiary, (ii) authorizes or approves, enters into any agreement contemplating or solicits stockholder
approval for any Fundamental Transaction or (iii) authorizes the voluntary dissolution, liquidation or winding up of the affairs
of the Company, then the Company shall deliver to the Holder a notice describing the material terms and conditions of such transaction
(but only to the extent such disclosure would not result in the dissemination of material, non-public information to the Holder)
at least 10 calendar days prior to the applicable record or effective date on which a Person would need to hold Common Stock in
order to participate in or vote with respect to such transaction, and the Company will take all steps reasonably necessary in order
to ensure that the Holder is given the practical opportunity to exercise this Warrant prior to such time so as to participate in
or vote with respect to such transaction; provided, however, that the failure to deliver such notice or any defect therein shall
not affect the validity of the corporate action required to be described in such notice.

 

    	-6-

    	 

    

 

10.Payment of
Exercise Price. The Holder may pay the Exercise Price
in one of the following manners:

 

(a)Cash Exercise.
The Holder may deliver immediately available funds; or

 

(b)Cashless Exercise.
The Holder may notify the Company in an Exercise Notice of its election to utilize cashless exercise, in which event the Company
shall issue to the Holder the number of Warrant Shares determined as follows:

 

X = Y [(A-B)/A]

 

where:

 

X = the number of Warrant Shares
to be issued to the Holder.

 

Y = the number of Warrant Shares
with respect to which this Warrant is being exercised.

 

A = the average of the daily volume
weighted average price for the five Trading Days immediately prior to (but not including) the Exercise Date.

 

B = the Exercise Price.

 

For purposes of Rule 144 promulgated under
the Securities Act, it is intended, understood and acknowledged that the Warrant Shares issued in a cashless exercise transaction
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.

 

11.Limitations
on Exercise. Notwithstanding anything to the contrary contained herein, the number of Warrant Shares that may be acquired by
the Holder upon any exercise of this Warrant (or otherwise in respect hereof) shall be limited to the extent necessary to ensure
that, following such exercise (or other issuance), the total number of shares of Common Stock then beneficially owned by such Holder
and its Affiliates and any other Persons whose beneficial ownership of Common Stock would be aggregated with the Holder’s
for purposes of Section 13(d) of the Exchange Act, does not exceed 9.99% of the total number of issued and outstanding shares of
Common Stock (including for such purpose the shares of Common Stock issuable upon such exercise). For such purposes, beneficial
ownership shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder.
This provision shall not restrict the number of shares of Common Stock which a Holder may receive or beneficially own in order
to determine the amount of securities or other consideration that such Holder may receive in the event of a Fundamental Transaction
as contemplated in Section 9 of this Warrant. 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.

 

    	-7-

    	 

    

 

12.No Fractional
Shares. No fractional shares of Warrant Shares will be issued in connection with any exercise of this Warrant. In lieu of any
fractional shares which would, otherwise be issuable, the Company shall pay cash equal to the product of such fraction multiplied
by the closing price of one Warrant Share as reported by the applicable Trading Market on the date of exercise.

 

13.Notices.
Any and all notices or other communications or deliveries hereunder (including, without limitation, any Exercise Notice) shall
be in writing and shall be deemed given and effective on the earliest of (i) the date of transmission, if such notice or communication
is delivered via facsimile at the facsimile number specified in this Section prior to 5:30 p.m. (New York City time) on a Trading
Day, (ii) the next Trading Day after the date of transmission, if such notice or communication is delivered via facsimile at the
facsimile number specified in this Section on a day that is not a Trading Day or later than 5:30 p.m. (New York City time) on any
Trading Day, (iii) the Trading Day following the date of mailing, if sent by nationally recognized overnight courier service, or

be: (i) if to the Company, to 9400 Toledo Way, Irvine, CA 92618, Attn: Chief Executive Officer, or to Facsimile No.: (949) 616-3399
(or such other address as the Company shall indicate in writing in accordance with this Section), or (ii) if to the Holder, to
the address or facsimile number appearing on the Warrant Register or such other address or facsimile number as the Holder may provide
to the Company in accordance with this Section.

 

14.Warrant Agent.
The Company shall serve as warrant agent under this Warrant. Upon 10 days’ notice to the Holder, the Company may appoint
a new warrant agent. Any corporation into which the Company or any new warrant agent may be merged or any corporation resulting
from any consolidation to which the Company or any new warrant agent shall be a party or any corporation to which the Company or
any new warrant agent transfers substantially all of its corporate trust or shareholders services business shall be a successor
warrant agent under this Warrant without any further act. Any such successor warrant agent shall promptly cause notice of its succession
as warrant agent to be mailed (by first class mail, postage prepaid) to the Holder at the Holder’s last address as shown
on the Warrant Register.

 

15.Miscellaneous.

 

(a)This Warrant shall
be binding on and inure to the benefit of the parties hereto and their respective successors and assigns. Subject to the preceding
sentence, nothing in this Warrant shall be construed to give to any Person other than the Company and the Holder any legal or equitable
right, remedy or cause of action under this Warrant. This Warrant may be amended only in writing signed by the Company and the
Holder and their successors and assigns. The foregoing sentence shall be subject to the restrictions on waivers and amendments
set forth in Section 11 of this Warrant.

 

    	-8-

    	 

    

 

(b)All questions
concerning the construction, validity, enforcement and interpretation of this Warrant shall be governed by and construed and enforced
in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof. Each
party agrees that all legal proceedings concerning the interpretations, enforcement and defense of this Warrant and the transactions
herein contemplated (“Proceedings”) (whether brought against a party hereto or its respective Affiliates, employees
or agents) shall be commenced exclusively in the New York Courts. Each party hereto hereby irrevocably submits to the exclusive
jurisdiction of the New York Courts 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 Proceeding, any claim that
it is not personally subject to the jurisdiction of any New York Court, or that such Proceeding has been commenced in an improper
or inconvenient forum. Each party hereto hereby irrevocably waives personal service of process and consents to process being served
in any such Proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery)
to such party at the address in effect for notices to it under this Warrant 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. Each party hereto hereby irrevocably waives, to the fullest extent permitted by applicable
law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Warrant or the transactions
contemplated hereby. If either party shall commence a Proceeding to enforce any provisions of this Warrant, 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.

 

(c)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.

 

(d)In case any one
or more of the provisions of this Warrant shall be invalid or unenforceable in any respect, the validity and enforceability of
the remaining terms and provisions of this Warrant shall not in any way be affected or impaired thereby and the parties will attempt
in good faith to agree upon a valid and enforceable provision which shall be a commercially reasonable substitute therefor, and
upon so agreeing, shall incorporate such substitute provision in this Warrant.

 

(e)Prior to exercise
of this Warrant, the Holder hereof shall not, by reason of being a Holder, be entitled to any rights of a stockholder with respect
to the Warrant Shares.
