          This Note has been entered into pursuant to the terms of a subscription agreement between the Borrower, the Holder and certain other holders (the "Other Holders") of convertible promissory notes (the "Other Notes"), dated of even date herewith (the "Subscription Agreement"), and shall be governed by the terms of such Subscription Agreement. Unless otherwise separately defined herein, all capitalized terms used in this Note shall have the same meaning as is set forth in the Subscription Agreement. The following terms shall apply to this Note:

ARTICLE I

INTEREST; AMORTIZATION

           1.1.       Interest Rate . Subject to Section 6.7 hereof, interest payable on this Note shall accrue on the outstanding Principal Amount at a rate per annum (the "Interest Rate") of twelve percent (12%).

          1.2.      Minimum Monthly Principal Payments . Amortizing payments of the outstanding Principal Amount of this Note and accrued interest shall commence on February 11, 2009 and on the same day of each month thereafter (each a "Repayment Date") until the Principal Amount has been repaid in full, whether by the payment of cash or by the conversion of such Principal Amount and interest into Common Stock pursuant to the terms hereof. Subject to Section 2.1 and Article 3 below, on each

Repayment Date, the Borrower shall make payments to the Holder in an amount equal to 14.28% of the initial Principal Amount, the amount of accrued but unpaid or unconverted interest on the entire Principal Amount as of such Repayment Date, and any other amounts which are then owing under this Note that have not been paid (collectively, the "Monthly Amount"). Amounts of conversions of Principal Amount made by the Holder or Borrower pursuant to Section 2.1 or Article III and amounts redeemed pursuant to Section 2.3 of this Note shall be applied first against outstanding fees and damages, then outstanding already payable accrued interest and then to Principal Amounts of not yet due Monthly Amounts commencing with the last Monthly Amount next payable and thereafter to Monthly Amounts in reverse chronological order. Any Principal Amount, interest and any other sum arising under this Note and the Subscription Agreement that remains outstanding on the Maturity Date shall be due and payable on the Maturity Date.

          1.3.      Mandatory Repayment . The entire Principal Interest and all other sums due under and in connection with this Note and the Transaction Documents shall be immediately due and payable upon the Borrower’s receipt of the net proceeds from the sale and issuance by the Borrower and/or a Subsidiary of Borrower of Debt and/or Equity for the gross amount of $3,000,000 in a single or series of offerings of such debt and/or equity.

Following the occurrence and during the continuance of an Event of Default (as defined in Article IV), which, if susceptible to cure is not cured within twenty (20) days, otherwise then from the first date of such occurrence, the annual interest rate on this Note shall (subject to Section 6.7) be fifteen percent (15%). Such interest shall be due and payable together with regular scheduled Monthly Amounts.

ARTICLE II

CONVERSION AND REPAYMENT

          2.1.      Payment of Monthly Amount in Cash or Common Stock . Subject to Sections 2.3 and 3.2 hereof, the Borrower shall pay the Monthly Amount on the applicable Repayment Date at the Borrower’s election, in either of the following manners: (i) in cash equal to 110% of the Principal portion of the Monthly Amount and 100% of all other components of the Monthly Amount, or (ii) with Common Stock at an applied conversion rate equal to the lesser of (A) the Fixed Conversion Price (as defined in section 3.1 hereof), or (B) eighty percent (80%) of the average daily closing bid prices of the Common Stock as reported by Bloomberg L.P. for the Principal Market for the five trading days preceding such Repayment Date (as such amount may be adjusted as described herein). Amounts paid with cash or shares of Common Stock must be delivered to the Holder not later than three business days after the applicable Repayment Date. The Borrower must send notice to the Holder by confirmed telecopier not later than 6:00 PM, New York City time on the tenth calendar day preceding a Repayment Date notifying Holder of Borrower’s election to pay the Monthly Amount in cash or Common Stock. The Notice must state the amount of the Monthly Amount including a description of the components of such Monthly Amount and, to the extent possible, include supporting calculations. The same election must be made to all Holders and Other Holders. If such notice is not given, or is not timely given or if the Monthly Redemption Amount is not timely delivered, then the Holder shall at anytime thereafter have the right on three business days prior notice to the Borrower to elect to receive such Monthly Amount in cash or Common Stock as described in Sections (i) and (ii) above.

          2.2.       Restriction on Payments in Kind . Notwithstanding anything to the contrary herein, the Borrower may not exercise its right to pay any portion of the Monthly Amount with Common Stock without the Holder’s consent unless on the day the Common Stock issued as payment of a Monthly Redemption Amount (a) an exemption from registration of the resale of shares of Common Stock to be issued in payment

2

of the Monthly Amount is available to the Holder for the unrestricted public resale of the Conversion Shares pursuant to Rule 144(b)(1) of the 1933 Act without volume or manner of sale limitations, or such shares of Common Stock are included for the unrestricted pubic resale thereof in an effective registration statement filed with the Commission, (b) an Event of Default (or an event that with the passage of time or the giving of notice could become an Event of Default) hereunder has not occurred, (c) the delivery of such Common Stock to Holder is timely made, (d) the amount of Common Stock (based on the aggregate Conversion Price) that would be issued in satisfaction of the Monthly Amount may not exceed for the Holder and Other Holders, in the aggregate, who could receive such Common Stock, more than 33% of the aggregate daily trading volume of the Common Stock for the seven trading days preceding such Repayment Date, as reported by Bloomberg L.P. for the Principal Market, and (e) the Principal Market is either the OTC Bulletin Board, American Stock Exchange, Nasdaq Capital Market, Nasdaq National Market, or New York Stock Exchange ("Listing Condition") from and after thirty (30) days prior to a Repayment Date.

          2.3.       Optional Redemption . Provided an Event of Default or an event which with the passage of time or the giving of notice would become an Event of Default is not pending, then the Borrower will have the option of prepaying the unpaid and unconverted Principal Amount then outstanding under this Note and the Other Notes ("Optional Redemption"), in whole or in part in increments of not less than $100,000, or the entire outstanding balance if less than $100,000 in the aggregate on this Note and the Other Notes, by paying to the Holder a sum of money equal to the Redemption Amount described below. Borrower’s election to exercise its right to prepay must be by notice in writing ("Notice of Redemption"). The Redemption Amount shall equal 125% of the outstanding Principal Amount being redeemed together with all interest accrued on this Note and all other amounts payable hereunder or pursuant to the Subscription Agreement. The Notice of Redemption shall specify the date for such Optional Redemption (the "Redemption Payment Date"), which date shall be twenty days after the date of the Notice of Redemption. A Notice of Redemption shall not be effective with respect to any portion of the principal amount under this Note for which the Holder has a pending election to convert or for which a Conversion Notice is given prior to the Redemption Payment Date. On the Redemption Payment Date, the Redemption Amount, less any portion of the Redemption Amount against which the Holder has previously exercised its rights pursuant to Section 3.1, shall be paid in good funds to the Holder. In the event the Borrower fails to pay the Redemption Amount on the Redemption Payment Date as set forth herein, then (i) at the Holder’s election, such Notice of Redemption will be null and void or Holder may enforce the Notice of Redemption, (ii) Borrower will not have the right to deliver another Notice of Redemption, and (iii) Borrower’s failure may be deemed by Holder to be a non-curable Event of Default. A Notice of Redemption may be cancelled at the option of the Holder, if at any time during the Redemption Period an Event of Default, or an event which with the passage of time or giving of notice would become an Event of Default (whether or not such Event of Default has been cured), occurs. Notices of Redemption must be given to the Holder and all Other Holders with respect to all amounts owed by Borrower to Holder and Other Holders in proportion to the outstanding Principal Amounts of the Notes and Other Notes held by the Holder and Other Holders on the date Notice of Redemption is given.

ARTICLE III

CONVERSION RIGHTS

          3.1.       Holder’s Conversion Rights . Subject to Section 3.2, the Holder shall have the right, but not the obligation, to convert all or any portion of the then aggregate outstanding Principal Amount of this Note, together with interest and fees due hereon, and any sum arising under the Subscription Agreement, and the Transaction Documents, including but not limited to Liquidated Damages, into shares of Common Stock, subject to the terms and conditions set forth in this Article III, at the rate of $0.05 per share of Common Stock ("Fixed Conversion Price"), as the same may be adjusted pursuant to this Note

3

and the Subscription Agreement. The Holder may exercise such right by delivery to the Borrower of a written Notice of Conversion pursuant to Section 3.3. Anything to the contrary herein notwithstanding, the Holder may convert up to one-twelfth (1/12 ^th ) of the initial Principal Amount of this Note, on a cumulative basis, each 30 days during the initial 180 days after the Issue Date at a conversion price equal to the lesser of (i) the Fixed Conversion Price, or (ii) eighty percent (80%) of the average daily closing bid prices of the Common Stock as reported by Bloomberg L.P. for the Principal Market for the five trading days preceding the date of the Notice of Conversion (as defined in Section 3.3) is given to the Borrower.

          3.2.      Conversion Limitation . Neither Holder nor the Borrower may convert on any date that amount of the Note Principal or interest in connection with that number of shares of Common Stock which would be in excess of the sum of (i) the number of shares of Common Stock beneficially owned by the Holder and its affiliates on a Conversion Date, Repayment Date, or interest payment date, as the case may be, (ii) any Common Stock issuable in connection with the unconverted portion of the Note, and (iii) the number of shares of Common Stock issuable upon the conversion of the Note with respect to which the determination of this provision is being made, which would result in beneficial ownership by the Holder and its affiliates of more than 4.99% of the outstanding shares of Common Stock of the Borrower on such Conversion Date. For the purposes of the provision to the immediately preceding sentence, beneficial ownership shall be determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended, and Regulation 13d-3 thereunder. Subject to the foregoing, the Holder shall not be limited to aggregate conversions of only 4.99% and aggregate conversion by the Holder may exceed 4.99% . The Holder shall have the authority and obligation to determine whether the restriction contained in this Section 2.3 will limit any conversion hereunder and to the extent that the Holder determines that the limitation contained in this Section applies, the determination of which portion of the Notes are convertible shall be the responsibility and obligation of the Holder. The Holder may waive the conversion limitation described in this Section 2.3, in whole or in part, upon and effective after 61 days prior written notice to the Borrower to increase such percentage to up to 9.99% .

          3.3.      Mechanics of Holder’s Conversion .

                         (a)      In the event that the Holder elects to convert any amounts outstanding under this Note into Common Stock, the Holder shall give notice of such election by delivering an executed and completed notice of conversion (a "Notice of Conversion") to the Borrower, which Notice of Conversion shall provide a breakdown in reasonable detail of the Principal Amount, accrued interest and amounts being converted. The original Note is not required to be surrendered to the Borrower until all sums due under the Note have been paid. On each Conversion Date (as hereinafter defined) and in accordance with its Notice of Conversion, the Holder shall make the appropriate reduction to the Principal Amount, accrued interest and fees as entered in its records. Each date on which a Notice of Conversion is delivered or telecopied to the Borrower in accordance with the provisions hereof shall be deemed a "Conversion Date." A form of Notice of Conversion to be employed by the Holder is annexed hereto as Exhibit A.

                         (b)      Pursuant to the terms of a Notice of Conversion, the Borrower will issue instructions to the transfer agent accompanied by an opinion of counsel (if so required by the Borrower’s transfer agent), and, except as otherwise provided below, shall cause the transfer agent to transmit the certificates representing the Conversion Shares to the Holder by crediting the account of the Holder’s designated broker with the Depository Trust Corporation ("DTC") through its Deposit Withdrawal Agent Commission ("DWAC") system within three (3) business days after receipt by the Borrower of the Notice of Conversion (the "Delivery Date"). In the case of the exercise of the conversion rights set forth herein, the conversion privilege shall be deemed to have been exercised and the Conversion Shares issuable upon

4

such conversion shall be deemed to have been issued upon the date of receipt by the Borrower of the Notice of Conversion. The Holder shall be treated for all purposes as the beneficial holder of such shares of Common Stock, or, in the case that Borrower delivers physical certificates as set forth below, the record holder of such shares of Common Stock, unless the Holder provides the Borrower written instructions to the contrary.
