All payments made hereunder shall be made in immediately available funds. By acceptance of this Note, the Payee represents, warrants, covenants and agrees that it will abide by and be bound by its terms. Capitalized terms not otherwise defined herein shall have the meaning set forth in that certain Securities Purchase Agreement dated October 3, 2005 by and between the Maker and the Payee. 1. Conversion. The Payee shall have the option at any time to convert all or a portion of the outstanding principal and interest on this Note into a number of shares of common stock, $0.001 par value per share (the "Common Stock") equal to a fraction, the numerator of which shall be the amount of principal and interest being so converted and the denominator of which shall be equal to the Conversion Price (the "Conversion Shares"). The "Conversion Price" shall be $0.02. 2. Restrictions on Conversion. Notwithstanding anything to the contrary contained herein, the number of Conversion Shares that may be acquired by the Payee upon any conversion of this Note (or otherwise in respect hereof) shall be limited to the extent necessary to insure that, following such conversion, the total number of shares of Common Stock then beneficially owned by such Payee and its affiliates and any other persons whose beneficial ownership of Common Stock would be aggregated with the Payee's for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), does not exceed 4.999% of the total number of issued and outstanding shares of Common Stock (including for such purpose the shares of Common Stock issuable upon such conversion). 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. 3. Prepayment. If at any time the Market Price (as defined below) of the Maker's Common Stock remains less than $0.03 cents for ten (10) consecutive trading days, then at the written election of the Payee provided not later than the 10th calendar day following the last day of such 10 trading day period, the Maker shall within 60 days of the receipt of such election prepay the principal amount outstanding at the time of such prepayment plus a premium (a "Prepayment Premium") equal to 40% of the principal amount being prepaid plus accrued interest. For the purposes of this Section 3, the "Market Price" shall equal the closing price per share of the Common Stock on such date as reported by a nationally recognized stock exchange price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed or quoted on the New York Stock Exchange, the American Stock Exchange, the Nasdaq National Market, the Nasdaq SmallCap Market or the OTC Bulletin Board, the bid price per share of the Common Stock on the primary market or exchange on which the Common Stock is then listed or quoted; (b) if prices for the Common Stock are then reported in the "Pink Sheets" published by the National Quotation Bureau Incorporated (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported; or (c) in all other cases, the fair market value of a share of Common Stock as determined by an independent qualified appraiser selected in good faith and paid for by the Payee. 4. Adjustment for Dividends, Distributions, Subdivisions, Combinations, Mergers, Consolidations or Sale of Assets. (a) Manner of Adjustment. (i) Stock Dividends, Distributions or Subdivisions. In the event the Maker shall issue shares of Common Stock in a stock dividend, stock distribution or subdivision, the Conversion Price in effect immediately before such stock dividend, stock distribution or subdivision shall, concurrently with the effectiveness of such stock dividend, stock distribution or subdivision, be proportionately decreased and the number of shares of Common Stock issuable upon conversion of this Note shall be proportionately increased. (ii) Combinations or Consolidations. In the event the outstanding shares of Common Stock shall be combined or consolidated, by reclassification or otherwise, into a lesser number of shares of Common Stock, the Conversion Price in effect immediately prior to such combination or consolidation shall, concurrently with the effectiveness of such combination or consolidation, be proportionately increased and the number of shares of Common Stock issuable upon conversion of this Note shall be proportionately decreased. (iii) Adjustment for Reclassification, Exchange or Substitution. In the event that the class of securities issuable upon the conversion of this Note shall be changed into the same or a different number of shares of any class or classes of stock, whether by capital reorganization, reclassification or otherwise, then and in each such event the Payee shall have the right thereafter to convert this Note for the kind and amount of shares of stock and other securities and property receivable upon such reorganization, reclassification, or other change, by Payees of the number of shares of the class of securities into which such Note might have been 2 convertible for immediately prior to such reorganization, reclassification, or change, all subject to further adjustment as provided herein. (iv) Adjustment for Merger, Consolidation or Sale of Assets. In the event that the Maker shall merge or consolidate with or into another entity or sell all or substantially all of its assets, this Note shall thereafter be convertible for the kind and amount of shares of stock or other securities or property to which a Payee of the number of shares of Common Stock of the Maker deliverable upon conversion of this Note would have been entitled upon such consolidation, merger or sale; and, in such case, appropriate adjustment (as determined in good faith by the Maker's Board of Directors) shall be made in the application of the provisions set forth in this Section 4 with respect to the rights and interest thereafter of the Payee of this Note, to the end that the provisions set forth in this Section 4 shall thereafter be applicable, as nearly as reasonably may be, in relation to any shares of stock or other property thereafter deliverable upon the conversion of this Note. (b) Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment of the Conversion Price pursuant to this Section 4, the Maker at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to the Payee a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based.
