Section 4. Conversion.

a) Voluntary Conversion. At any time after the Original Issue Date and until payment hereof in full (including interest), this Note shall be convertible into Note Shares at the option of the Holder, in whole or in part at any time and from time to time. The Holder shall effect conversions by delivering to the Company the form of Notice of Conversion attached hereto as Annex A (a “Notice of Conversion”), specifying therein the principal amount of Notes and interest thereon to be converted and the date on which such conversion is to be effected (a “Conversion Date”). If no Conversion Date is specified in a Notice of Conversion, the Conversion Date shall be the date that such Notice of Conversion is received hereunder. To effect conversions hereunder, the Holder shall not be required to physically surrender Notes to the Company unless the entire principal amount of this Note plus all accrued and unpaid interest thereon has been so converted. Conversions hereunder shall have the effect of lowering the outstanding principal amount of this Note in an amount equal to the applicable conversion. The Holder and the Company shall maintain records showing the principal amount converted and the date of such conversions. The Company shall deliver any objection to any Notice of Conversion promptly, but in no event later than 2 Business Days of receipt of such notice. 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. Conversion Notices shall be irrevocable, except as provided in Section 4.21 of the Purchase Agreement.

b) Conversion Price. The conversion price in effect on any Conversion Date shall be equal to the lower of the Original Conversion Price or the price as adjusted subject to Section 5 herein (the “Conversion Price”).

c) Mechanics of Conversion.

i. Note Shares Issuable Upon Conversion. The number of shares of Note Shares 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 plus all accrued and unpaid interest thereon by (y) the Conversion Price.

ii. Delivery of Certificate Upon Conversion. Not later than 7 Business Days after any Conversion Date, the Company will deliver to the Holder (A) a certificate or certificates representing the Note Shares representing the number of shares of Note Shares being acquired upon the conversion of this Note or a portion of this Note.

iii. Reservation of Certificates. Certificates for the Note Shares on conversion of this Note shall be made without charge to the Holder 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) shall pay a stock dividend or otherwise make 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) subdivide outstanding shares of Common Stock into a larger number of shares, (C) combine (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or (D) issue 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 treasury shares, if any) outstanding before such event and of which the denominator shall be the number of shares of Common Stock outstanding 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, shall offer, sell, grant any option to purchase or offer, sell or grant any right to re-price its securities, or otherwise dispose of or issue (or announce any offer, sale, grant or any option to purchase or other disposition) any Common Stock or Common Stock Equivalents entitling any Person to acquire shares of Common Stock, at an effective price per share less than the then Conversion Price (“Dilutive Issuance”), except for an Exempt Issuance, as adjusted hereunder (if the holder of the Common Stock or 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 is issued in connection with such issuance, be entitled to receive shares of Common Stock at an effective price per share which is less than the Conversion Price, such issuance shall be deemed to have occurred for less than the Conversion Price), then the Conversion Price shall be multiplied by a fraction of which the denominator shall be the number of shares of Common Stock issued and outstanding immediately prior to such Dilutive Issuance plus the number of additional shares of Common Stock offered for subscription or purchase in connection with such Dilutive Issuance, and of which the numerator shall be the number of shares of Common Stock issued and outstanding immediately prior to such Dilutive Issuance plus the number of shares which the aggregate offering price of the total number of shares so offered (assuming delivery to the Company in full of all consideration payable upon exercise of such rights, options or warrants) would purchase at the Conversion Price

c) 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 outstanding as of a given date shall be the sum of the aggregate number of issued and to be converted shares of Common Stock (excluding treasury shares, if any) outstanding.

7

d) Notice to Holders.

i. Adjustment to Conversion Price. Whenever the Conversion Price is adjusted pursuant to any of this Section 5, the Company shall promptly mail to the 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 Xxxxxx. 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 the Holder’s last address appearing on the stock books of the Company, 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 mail such notice or any defect therein or in the mailing 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 during the 20-day period commencing the date of such notice to the effective date of the event triggering such notice.

8

iii. 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 where the Company is not the surviving corporation, (B) the Company effects any sale of all or substantially all of its assets in one 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 Note Share that would have been issuable upon such conversion absent 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 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 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 Company will utilize its best efforts to ensure that 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 (c) and insuring that this Note (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction. Failure to obtain such terms by the Company shall not cause an Event of Default and the Holder shall then be required to convert in accordance with the terms of the Fundamental Transaction.

iv. Exempt Issuance. Notwithstanding the foregoing, no adjustment will be made under this Section 5 in respect of an Exempt Issuance.

9

Section 6. Redemption and Forced Conversion.

(a) Optional Redemption at Election of Company. Subject to the provisions of this Section 6, at any time after the Original Issuance Date, the Company may deliver a notice to the Holder (an “Optional Redemption Notice” and the date such notice is deemed delivered hereunder, the “Optional Redemption Notice Date”) of its revocable election to redeem this Note, for an amount, in cash, equal to the Optional Redemption Amount on the 60^th day following the Optional Redemption Notice Date (such date, the “Optional Redemption Date” and such redemption, the “Optional Redemption”). The Optional Redemption Amount is equal to the sum of the un-converted principal balance outstanding plus the aggregate accrued interest payable outstanding on the Optional Redemption Date and is due in full. The Company may only effect an Optional Redemption if during the period commencing on the Optional Redemption Notice Date through to the Optional Redemption Date, each of the Equity Conditions shall have been met. If any of the Equity Conditions shall cease to be satisfied at any time during the required period, then the Holder may elect to nullify the Optional Redemption Notice by notice to the Company within three (3) Business Days after the first day on which any such Equity Condition has not been met (provided that if, by a provision of the Transaction Documents the Company is obligated to notify the Holder of the non-existence of an Equity Condition, such notice period shall be extended to the third Business Day after proper notice from the Company) in which case the Optional Redemption Notice shall be null and void, ab initio. The Company covenants and agrees that it will honor all Conversion Notices tendered from the time of delivery of the Optional Redemption Notice through the date all amounts owing thereon are due and paid in full.

(b) Redemption Procedure. The payment of cash pursuant to an Optional Redemption shall be made on the Optional Redemption Date. If any portion of the cash payment for an Optional Redemption shall not be paid by the Company by the respective due date, interest shall accrue thereon at the rate of 15% per annum (or the maximum rate permitted by applicable law, whichever is less) until the payment of the Optional Redemption Amount plus all amounts owing thereon is paid in full. Alternatively, if any portion of the Optional Redemption Amount remains unpaid after such date, the Holders subject to such redemption may elect, by written notice to the Company given at any time thereafter, to invalidate ab initio such redemption. The Holder may elect to convert the outstanding principal amount of this Note pursuant to Section 4 prior to actual payment in cash for any redemption under this Section 6 by fax delivery of a Notice of Conversion to the Company.

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):

10

i. any default in the payment of (A) the principal of amount of this Note, or (B) interest (including Late Fees) on, or liquidated damages in respect of, this Note, in each case free of any claim of subordination, 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, solely in the case of an interest payment or other default under clause (B) above, is not cured, within 15 Business Days;

ii. the Company shall fail to deliver certificates representing Note Shares issuable upon a conversion or redemption hereunder that comply with the provisions hereof prior to the 15^th Business Day after such shares are required to be delivered hereunder, or the Company shall provide written notice to the Holder, including by way of public announcement, at any time, of its intention not to comply with requests for conversion or redemption of this Note in accordance with the terms hereof;

iii. the Company shall fail to have available a sufficient number of authorized and unreserved shares of Common Stock to issue to the Holder upon a conversion hereunder;

iv. the Company shall materially fail to observe or perform any other covenant, agreement or warranty contained in, or otherwise commit any breach of the Transaction Documents to which the Holder is a party, and such failure or breach shall not, if subject to the possibility of a cure by the Company, have been remedied within 30 calendar days after the date on which written notice of such failure or breach shall have been given;

v. the Company shall purchase more than a de minimis number of Common Stock Equivalents (not including a redemption of this Note hereunder);

vi. there shall have occurred a Bankruptcy Event;

b) Remedies Upon Event of Default. If any Event of Default occurs and is continuing, the full principal amount of this Note, together with interest and other amounts owing in respect thereof, to the date of acceleration shall become, at the Holder’s election, immediately due and payable in cash. Commencing 5 days after the occurrence of any Event of Default that results in the eventual acceleration of this Note, the interest rate on this Note shall accrue at the rate of 15% per annum, or such lower maximum amount of interest permitted to be charged under applicable law. When this Note shall have been paid in full in accordance herewith, the Holder shall promptly surrender this Note to or as directed by the Company. The Holder need not provide and the Company hereby waives any presentment, demand, protest or other notice of any kind, and the Holder may immediately and without expiration of any grace period enforce any and all of its rights and remedies hereunder and all other remedies available to it under applicable law. Such declaration may be rescinded and annulled by Xxxxxx at any time prior to payment hereunder and the Holder shall have all rights as a Note holder until such time, if any, as the full payment under this Section shall have been received by it. No such rescission or annulment shall affect any subsequent Event of Default or impair any right consequent thereon.

11

Section 8. Miscellaneous.

a) Notices. Any and all notices or other communications or deliveries to be provided by the Holder hereunder, including, without limitation, any Notice of Conversion, shall be in writing and delivered either personally, by facsimile or sent by a nationally recognized overnight courier service, addressed to the Company at the address set forth above, facsimile number 213.947.1914, Attn: Chief Executive Officer or such other address or facsimile number as the Company may specify for such purposes by notice to the Holder delivered in accordance with this Section, with any fax delivery followed up by overnight delivery service.

This Note is a direct debt obligation of the Company. This Note ranks pari passu with all other Notes now or hereafter issued under the terms set forth herein.

c) Subordinated Security Interest. This Note is a general obligation of the Company and is specifically subordinate in all ways to any Superior Indebtedness now or hereafter created, issued made or outstanding, to or held by any Secured Parties.

f) Waiver. Any waiver by the Company or the Holder of a breach of any provision of this Note shall not operate as or be construed to be a waiver of any other breach of such provision or of any breach of any other provision of this Note. The failure of the Company or the Holder to insist upon strict adherence to any term of this Note on one or more occasions shall not be considered a waiver or deprive that party of the right thereafter to insist upon strict adherence to that term or any other term of this Note. Any waiver must be in writing.

g) 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 the extent it may lawfully do so) hereby expressly waives all benefits or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impeded the execution of any power herein granted to the Holder, but will suffer and permit the execution of every such as though no such law has been enacted.

13
