CONVERSION BY LENDER 2.1 Conversion by Lender - The Principal Sum of this Note, together with any unpaid interest thereon, will be convertible by the Lender, upon notice being given by the Lender to the Company in the manner specified in subsection 2.2 below, into fully paid, non-assessable shares of the Company's $.001 par value common stock at a price of $0.45 per share (the "Conversion Price"). The Conversion Price is subject to adjustment under section 4 below. The shares of common stock issued upon conversion will be recorded on the books of the Company as of the Conversion Date in the name of the Lender or its nominee, and will rank pari passu with the issued and fully paid shares of the Company of the same class outstanding on the Conversion Date, and the Lender will accordingly be entitled to any dividends or other distributions declared, made, or paid on or after such Conversion Date. If the number of shares to be issued to the Lender on conversion of this Note is not a whole number, then the number of the shares shall be rounded down to the nearest whole number. 2.2 Conversion Procedures. The Lender may exercise its right of conversion by: (a) delivering by hand or by registered mail to the principal office of the Company as set out on page 1 hereof, or to such other address as the Company may from time to time in writing advise, a Notice of Conversion in the form attached as "Schedule A" hereto, such Notice to be received by the Company on or before the Maturity Date and prior to repayment by the Company. The date on which the Notice is received by the Company is herein called the "Conversion Date"; and (b) surrendering this Note to the Company in exchange for a certificate for the appropriate number of shares. Surrender of the Note by the Lender to the Company shall be a good and sufficient discharge to the Company, subject to the delivery of a share certificate for the appropriate number of Shares, of the debt evidenced by this Note or of any lesser amount converted and, if less than the full amount of debt represented by the Note is converted, the Company shall deliver to the Lender a replacement Note representing the balance of the debt which remains outstanding; and 3 (c) delivering to the Company an investment representation letter sufficient to permit the Company to issue the shares deliverable upon conversion in a manner believed to be exempt from registration under the Act. 2.3. Payment Obligation Ceases. The obligation of the Company to repay the Principal Sum of the Note and pay interest on the Note or any portion thereof, as applicable, shall cease on the Conversion Date as to the amount of the Principal Sum and accrued interest which is converted to shares of common stock pursuant to Section 2.2. 3. AVAILABLE AUTHORIZED CAPITAL 3.1 The Company will, at all times while this Note is outstanding, keep available shares of authorized and unissued common stock sufficient to enable the Principal Sum evidenced by this Note from time to time outstanding and unconverted, together with accrued and unpaid interest thereon, to be converted to shares of common stock in accordance with this Note. 3.2 The Company represents and warrants that the shares of common stock issuable upon conversion or in payment of the Note, when issued in compliance with the terms of this Note, will be validly issued, fully paid and non-assessable shares of common stock of the Company, and will be free of any liens, charges or encumbrances. 4. ADJUSTMENT OF CONVERSION PRICE AND SHARES 4.1 If the Company shall at any time subdivide its outstanding common stock by recapitalization, reclassification or split-up thereof, the number of shares of common stock subject to this Note immediately prior to such subdivision shall be proportionately decreased, and if the Company shall at any time combine the outstanding common stock by recapitalization, reclassification or combination thereof, the number of shares of common stock underlying this Note immediately prior to such combination shall be proportionately increased. Any corresponding adjustment to the Conversion Price shall become effective at the close of business on the record date for such subdivision or combination. 4.2 In the event of a dividend (other than in shares of common stock of the Company), the proposed dissolution or liquidation of the Company, or any corporate separation or division, including, but not limited to, a split-up, split-off or spin-off, or a merger or consolidation of the Company with another corporation, or the sale of all or substantially all of the assets of the Company, the Board may provide that the Lender will have the right to convert this Note (at its then current Conversion Price) solely for the kind and amount of shares of stock and other securities, property, cash or any combination thereof receivable upon such dissolution, liquidation, corporate separation or division, or merger or consolidation by a holder of the number of shares of common stock for which this Note might have been exercised immediately prior to such dissolution, liquidation, corporate separation or division, or merger or consolidation; or, in the alternative, the Board may provide that this Note will terminate as of a date fixed by the Board; provided, however, that not less than 30 days' written notice of the date so fixed must be given to the Lender who will have the right, during the period of 30 days preceding such termination, to convert this Note into common stock. 4 4.3 The preceding paragraph will not apply to a merger or consolidation in which the Company is the surviving corporation and shares of common stock are not converted into or exchanged for stock, securities of any other corporation, cash or any other thing of value. Notwithstanding the preceding sentence, in case of any consolidation or merger of another corporation into the Company in which the Company is the surviving corporation and in which there is a reclassification or change (including a change to the right to receive cash or other property) of the shares of common stock (excluding a change in par value, or from no par value to par value, or any change as a result of a subdivision or combination, but including any change in such shares into two or more classes or series of shares), the Board may provide that the Lender will have the right to convert this Note solely for the kind and amount of shares of stock and other securities (including those of any new direct or indirect parent of the Company), property, cash or any combination thereof receivable upon such reclassification, change, consolidation or merger by the holder of the number of shares of common stock into which this Note might have been converted. 4.4 In the event of a change in the common stock of the Company as presently constituted into the same number of shares with a different par value, the shares resulting from any such change will be deemed to be the common stock of the Company within the meaning of this agreement. 4.5 To the extent that the foregoing adjustments relate to stock or securities of the Company, such adjustments will be made in good faith by the Board. 4.6 Except as expressly provided in this Note, the Lender will have no rights by reason of any subdivision or consolidation of shares of stock of any class, or the payment of any stock dividend or any other increase or decrease in the number of shares of stock of any class, or by reason of any dissolution, liquidation, merger, or consolidation or spin-off of assets or stock of another corporation; and any issue by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, will not affect, and no adjustment will be made with respect to, the number or price of shares of common stock subject to this Note. The issuance of this Note will not affect in any way the right or power of the Company to make adjustments, reclassifications, reorganizations or changes of its capital or business structures, or to merge or consolidate, or to dissolve, liquidate, or sell or transfer all or any part of its business or assets. 5.
