Registration of Transfers and Exchanges. 
 a) Different Denominations. This Note is exchangeable for an equal aggregate

 b) Investment Representations. This Note has been issued subject to certain investment representations of the original Holder set forth in the

Holder or transferee of this Note, as the case may be, furnish to the Company a written opinion of counsel (which opinion shall be in form, substance and scope customary for opinions of counsel in comparable transactions) to the effect that such

whether or not this Note is overdue, and neither the Company nor any such agent shall be affected by notice to the contrary. 
 Section 4. Conversion. 
 a) Voluntary Conversion. At any time commencing after the
Original Issue Date until this Note is no longer outstanding, this Note may be converted into shares of Common Stock at the option of the Holder, at any time and from time to time. The Holder shall effect conversions by delivering to the Company a
Notice of Conversion, the form of which is attached hereto as Annex A (a “Notice of Conversion”), specifying therein the principal amount of this Note to be converted and the date on which such conversion shall be effected (a
“Conversion Date”). Any partial conversion shall be for increments of $1,000 in principal amount, unless the Holder is converting the entire remaining principal amount of this Debenture. If no Conversion Date is specified in a
Notice of Conversion, the Conversion Date shall be the date that such Notice of Conversion is deemed delivered hereunder. To effect conversions hereunder, the Holder shall not be required to physically surrender this Note to the Company unless the
entire principal amount of this Note thereon has been so converted. Conversions hereunder shall have the effect of lowering the outstanding principal amount of this in an amount equal to the applicable conversion. The Holder and the Company shall
maintain records in the Note Register showing the principal amount(s) converted and the date of such conversion(s). The Company may deliver an objection to any Notice of Conversion within 1 Business Day of receipt of such Notice of Conversion. In
the event of any dispute or discrepancy, the records of the Holder shall be controlling and determinative in the absence of manifest error. The Holder and any assignee, by acceptance of this Note, acknowledge and agree that, by reason of the
provisions of this paragraph, following conversion of a portion of this Note, the unpaid and unconverted principal amount of this Note may be less than the amount stated on the face hereof. 
 b) Conversion Price. The conversion price shall be equal to $0.247 per share of Common Stock (the “Conversion
Price”), subject to adjustment as set forth herein. 
 c) Mechanics of Conversion 
 i. Conversion Shares Issuable Upon Conversion of Principal Amount. The number of shares of Common Stock issuable upon a conversion
hereunder shall be determined by the quotient obtained by dividing (x) the outstanding principal amount of this Note to be converted by (y) the Conversion Price. 

 ii. Delivery of Certificate Upon Conversion. Not later than three (3) Trading
Days after any Conversion Date (the “Share Delivery Date”), the Company shall deliver or cause to be delivered to the Holder a certificate or certificates representing the Conversion Shares which shall be free of restrictive legends
and trading restrictions (other than those required by law) representing the number of shares of Common Stock being acquired upon the conversion of this Note. The Company shall, if available and if allowed under applicable securities laws, use its
best efforts to deliver any certificate or certificates required to be delivered by the Company under this Section electronically through the Depository Trust Corporation or another established clearing corporation performing similar functions.

 iii. Failure to Deliver Certificates. If in the case of any Notice of Conversion such certificate or certificates
are not delivered to or as directed by the applicable Holder by the third Trading Day after a Conversion Date, the Holder shall be entitled by written notice to the Company at any time on or before its receipt of such certificate or certificates
thereafter, to rescind such conversion, in which event the Company shall immediately return the certificates representing the principal amount of this Note tendered for conversion. 
 iv. Reservation of Shares Issuable Upon Conversion. Prior to September 30, 2008, the Company shall take all action required by
law to submit to the shareholders of the Company a proposal to amend the Company’s articles of incorporation to increase the number of authorized shares of Common Stock by such amount as is necessary to reserve for issuance the maximum
aggregate number of Conversion Shares then issued or potentially issuable in the future upon the conversion of the outstanding principal amount of this Note. If, on any date after the articles of incorporation of the Company are amended to increase
the number of authorized shares of Common Stock, the number of authorized but unissued (and otherwise unreserved) shares of Common Stock is less than the number of Conversion Shares issuable hereunder, then the board of directors of the Company
shall use commercially reasonable efforts to amend the Company’s articles of incorporation to increase the number of authorized but unissued shares of Common Stock to at least the maximum number of Conversion Shares issuable upon conversion of
the then outstanding principal of this Note as soon as possible and in any event not later than the 75th day after such date. The Company covenants that all shares of Common Stock that shall be so issuable shall, upon issue, be duly and validly
authorized, issued and fully paid, nonassessable. 
 v. Fractional Shares. Upon a conversion hereunder the Company
shall not be required to issue stock certificates representing fractions of shares of the Common Stock, but may if otherwise permitted, make a cash payment in respect of any final fraction of a share based on the Closing Price at such time. If the
Company elects not, or is unable, to make such a cash payment, the Holder shall be entitled to receive, in lieu of the final fraction of a share, one whole share of Common Stock. 

 vi. Transfer Taxes. The issuance of certificates for shares of the Common Stock on
conversion of this Note shall be made without charge to the Holder hereof for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery of such certificate, provided that the Company shall not be required to pay
any tax that may be payable in respect of any transfer involved in the issuance and delivery of any such certificate upon conversion in a name other than that of the Holder of this Note so converted and the Company shall not be required to issue or
deliver such certificates unless or until the person or persons requesting the issuance thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid.

 Section 5. Certain Adjustments. 
 a) Stock Dividends and Stock Splits. If the Company, at any time while this Note is outstanding: (A) pays a stock dividend or
otherwise makes a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued
by the Company pursuant to this Note), (B) subdivides outstanding shares of Common Stock into a larger number of shares, (C) combines (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of
shares, or (D) issues by reclassification of shares of the Common Stock any shares of capital stock of the Company, then the Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock
(excluding any treasury shares of the Company) 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 this
Section shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision,
combination or re-classification. 
 b) Subsequent Equity Sales. If the Company at any time while this Note is
outstanding, sells or grants any option to purchase or sells or grants any right to reprice its securities, or otherwise disposes of or issues (or announces any sale, grant or any option to purchase or other disposition) any Common Stock Equivalents
entitling any Person to acquire shares of Common Stock at an effective price per share that is lower than the then in effect Conversion Price (such lower price, the “Base Conversion Price” and such issuances collectively, a “Dilutive
Issuance”) (if the holder of the Common Stock Equivalents so issued shall at any time, whether by operation of purchase price adjustments, reset provisions, floating conversion, exercise or exchange prices or otherwise, or due to warrants,
options or rights per share which are issued in connection with such issuance, be entitled to receive shares of Common Stock at an effective price per share that is lower than the Conversion Price, such issuance shall be deemed to have occurred for
less than the Conversion Price on such date of the Dilutive Issuance), then the Conversion Price shall be reduced to equal the Base Conversion Price. Such adjustment shall be made whenever such 

 
Common Stock Equivalents are issued. Notwithstanding the foregoing, no adjustment will be made under this Section 5(b) in respect of an Exempt Issuance.
The Company shall notify the Holder in writing, no later than the Business Day following the issuance of any Common Stock or Common Stock Equivalents subject to this Section 5(b), indicating therein the applicable issuance price, or applicable
reset price, exchange price, conversion price and other pricing terms (such notice, the “Dilutive Issuance Notice”). For purposes of clarification, whether or not the Company provides a Dilutive Issuance Notice pursuant to this
Section 5(b), upon the occurrence of any Dilutive Issuance, the Holder is entitled to receive a number of Conversion Shares based upon the Base Conversion Price on or after the date of such Dilutive Issuance, regardless of whether the Holder
accurately refers to the Base Conversion Price in the Notice of Conversion. 
 c) Pro Rata Distributions. If the
Company, at any time while this Note is outstanding, shall distribute to all holders of Common Stock (and not to the holders of the Notes) evidences of its indebtedness or assets (including cash and cash dividends) or rights or warrants to subscribe
for or purchase any security, then in each such case the Conversion Price shall be adjusted by multiplying such Conversion Price in effect immediately prior to the record date fixed for determination of stockholders entitled to receive such
distribution by a fraction of which the denominator shall be the Closing Price determined as of the record date mentioned above, and of which the numerator shall be such Closing Price on such record date less the then fair market value at such
record date of the portion of such assets or evidence of indebtedness so distributed applicable to one (1) outstanding share of the Common Stock as determined by the Board of Directors of the Company in good faith. In either case the
adjustments shall be described in a statement delivered to the Holder describing the portion of assets or evidences of indebtedness so distributed or such subscription rights applicable to one share of Common Stock. Such adjustment shall be made
whenever any such distribution is made and shall become effective immediately after the record date mentioned above. 
 d)
Fundamental Transaction. If, at any time while this Note is outstanding, (A) the Company effects any merger or consolidation of the Company with or into another Person, (B) the Company effects any sale of all or substantially all of
its assets in one transaction or a series of related transactions, (C) any tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to tender or exchange
their shares for other securities, cash or property, or (D) the Company effects any reclassification of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other
securities, cash or property (in any such case, a “Fundamental Transaction”), then upon any subsequent conversion of this Note, the Holder shall have the right to receive, for each Conversion Share that would have been issuable upon
such conversion immediately prior to the occurrence of such Fundamental Transaction, the same kind and amount 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 one (1) share of Common Stock (the “Alternate Consideration”). For purposes of any such conversion, the determination of the Conversion Price shall be
appropriately adjusted to apply to such Alternate Consideration 

 
based on the amount of Alternate Consideration issuable in respect of one (1) share of Common Stock in such Fundamental Transaction, and the Company
shall apportion the Conversion 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 conversion of this Note following such Fundamental Transaction. To the
extent necessary to effectuate the foregoing provisions, any successor to the Company or surviving entity in such Fundamental Transaction shall issue to the Holder a new Note consistent with the foregoing provisions and evidencing the Holder’s
right to convert such Note into Alternate Consideration. 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 (d) and insuring that this Note (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction. 
 e) Calculations. All calculations under this Section 5 shall be made to the nearest cent or the nearest 1/100th of a share, as
the case may be. For purposes of this Section 5, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding treasury shares of the Company)
issued and outstanding. 
 f) Notice to the Holder. 
 i. Adjustment to Conversion Price. Whenever the Conversion Price is adjusted pursuant to any provision of this Section 5, the
Company shall promptly mail to each Holder a notice setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment. 
 ii. Notice to Allow Conversion by Holder. If (A) the Company shall declare a dividend (or any other distribution) on the
Common Stock; (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock; (C) the Company shall authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or
purchase any shares of capital stock of any class or of any rights; (D) the approval of any stockholders of the Company shall be required in connection with any reclassification of the Common Stock, any consolidation or merger to which the
Company is a party, any sale or transfer of all or substantially all of the assets of the Company, of any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property; (E) the Company shall authorize
the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company; then, in each case, the Company shall cause to be filed at each office or agency maintained for the purpose of conversion of this Note, and shall
cause to be mailed to the Holder at its last address as it shall appear upon the Note Register, at least 20 

 
calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for
the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions, redemption, rights or
warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the Common
Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange; provided, that the failure
to deliver such notice or any defect therein or in the delivery thereof shall not affect the validity of the corporate action required to be specified in such notice. The Holder is entitled to convert this Note or any portion thereof at any time
through during the 20-day period commencing the date of such notice to the effective date of the event triggering such notice in order for such converted Conversion Shares to be treated as Common Stock as of the record date of the applicable record
or effective date of the event triggering such notice. 
 Section 6. Registration of Conversion Shares. The Company shall
file a registration statement with the Securities and Exchange Commission (the “Commission”) under the Securities Act for the purpose of registering on or before January 9, 2009, resale of the Conversion Shares, and shall use its best
efforts to keep such registration statement continuously effective under the Securities Act until all such shares covered by such registration statement have been sold or may be sold without restriction pursuant to Rule 144 as determined by the
counsel to the Company pursuant to a written opinion letter to such effect. The Company shall not be obligated to file a registration statement with respect to any Conversion Shares that have been sold or may be sold without restriction pursuant to
Rule 144 as determined by the counsel to the Company pursuant to a written opinion letter to such effect. If: (i) a registration statement is not effective with respect to any Conversion Shares the Company is obligated to register for resale on
or before the date specified above; or (ii) after the effective date a registration statement ceases for any reason to remain continuously effective for all Conversion Shares for which it is required to be effective, or the Holder is not
permitted to utilize the prospectus therein to resell such shares for 20 consecutive trading days, but no more than an aggregate of 40 trading days during any 12-month period (which need not be consecutive trading days) (any such failure or breach
being referred to as an “Event”, and for purposes of clause (i) the date on which such Event occurs, or for purposes of clause (ii) the date on which such 20 or 40 trading day period, as applicable, is exceeded being
referred to as “Event Date”), then within 10 days following each such Event Date and within 10 days following each monthly anniversary of each such Event Date (if the applicable Event shall not have been cured by such monthly
anniversary date) until the applicable Event is cured, the Company shall pay to each Holder an amount in cash, as liquidated damages and not as a penalty, equal to 1.0% of the aggregate market value on the Event Date of the Conversion Shares that
are not so registered or cannot be sold under an effective registration statement. The Holder shall provide to the Company in writing all information reasonably required by the Company to comply with its disclosure obligations in the registration
statement imposed by the Securities Act and the regulations 

 
promulgated thereunder. The failure of the Holder for any reason to provide such information at least five Business Days prior to the filing of the
registration statement covering the Conversion Shares shall effect a termination of any obligation of the Company to file any registration statement pertaining to the Conversion Shares and the Company shall have no liability to the Holder with
respect to the liquidated damages stated above. 
 Section 7. Events of Default. 
 a) “Event of Default”, wherever used herein, means any one of the following events (whatever the reason and whether it
shall be voluntary or involuntary or effected by operation of law or pursuant to any judgment, decree or order of any court, or any order, rule or regulation of any administrative or governmental body): 
 i. any default in the payment of the principal amount of this Note, as and when the same shall become due and payable (whether on a
Conversion Date or the Maturity Date or by acceleration or otherwise) which default under clause (B) above, is not cured, within 3 Trading Days; 
 ii. the Company shall fail to observe or perform any other covenant or agreement contained in this Note or any other Note (other than a breach by the Company of its obligations to deliver shares of Common Stock to the
Holder upon conversion) which failure is not cured, if possible to cure, within the earlier to occur of (A) 5 Trading Days after notice of such default sent by the Holder or by any other Holder and (B)10 Trading Days after the Company shall
become or should have become aware of such failure;

 d) Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Note shall be

state and federal courts sitting in the City of Costa Mesa, California (the “California Courts”). Each party hereto hereby irrevocably submits to the exclusive jurisdiction of the California Courts for the adjudication of any
dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in

 f) Severability. If any provision of this Note is invalid, illegal or
unenforceable, the balance of this Note shall remain in effect, and if any provision is inapplicable to any person or circumstance, it shall nevertheless remain applicable to all other persons and circumstances. If it shall be found that any
interest or other amount deemed interest due hereunder violates applicable laws governing usury, the applicable rate of interest due hereunder shall automatically be lowered to equal the maximum permitted rate of interest. The Company covenants (to
the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law which would prohibit or forgive the Company
from paying all or any portion of the principal of or interest on this Note as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this indenture, and the Company (to
