  2.1.          Conversion into the Borrower's Common Stock as defined below.
  (a)            Subject to the terms of the Note, the Holder shall have the right from and after the date of issuance and then at any time until this Note is fully paid, to convert any outstanding and unpaid principal portion of this Note, and accrued interest, at the election of the Holder (the date of giving of such notice of conversion being a "Conversion Date") into fully paid and nonassessable units of securities of the Borrower at the rate of US$0.08 (the "Conversion Price") of the principal amount or accrued interest due under the Note converted, with each unit comprised of one common share, no par value, in the capital of the Borrower (the “Common Stock”) and one-half share purchase warrant with each full warrant enabling the purchase of an additional common share of the Borrower at $0.12 per share for a three year term from the date of issuance of this Note (the “Warrant Shares”), or such pro-rata number of units that may result from a change in the capital stock of Borrower as a result of a share split, consolidation or reclassification, as described below. Upon delivery to the Borrower of a completed Notice of Conversion, a form of which is annexed hereto, Borrower shall issue and deliver to the Holder within seven (7) business days from the date the Holder has delivered the Notice to the Borrower (the “Conversion Date”) (such seventh day being the “Delivery Date”) that number of shares of Common Stock and Share Purchase Warrants for the portion of the Note and accrued interest converted in accordance with the foregoing. At the election of the Holder, the Borrower will deliver accrued but unpaid interest on the Note in the manner provided in Section 1.3 through the Conversion Date directly to the Holder on or before the Delivery Date. The number of common stock and warrants to be issued upon each conversion of this Note shall be determined by dividing that portion of the principal of the Note and accrued interest to be converted, by the Conversion Price. Any accrued interest which the Holder has not converted at the same time as conversion of principal will be treated as Note principal due on the Maturity Date.
  (b)            As evidenced and defined above, and subject to adjustment as provided in Section 2.1(c) hereof, the Conversion Price per share shall be US$0.08.
  (c)            The certificates representing the shares and warrants issuable on Conversion will carry a restrictive legend as required under applicable securities law and regulatory policy.
  (d)            The Conversion Price and number and kind of shares and warrants to be issued upon conversion determined pursuant to Section 2.1(a), shall be subject to adjustment from time to time upon the happening of certain events while this conversion right remains outstanding, as follows:
  A. Merger, Sale of Assets, etc. If the Borrower at any time shall consolidate with or merge into or sell or convey all or substantially all its assets to any other corporation, this Note, as to the unpaid principal portion thereof and accrued interest thereon, shall thereafter be deemed to evidence the right to purchase such number and kind of shares or other securities and property as would have been issuable or distributable on account of such consolidation, merger, sale or conveyance, upon or with respect to the securities subject to the conversion or purchase right immediately prior to such consolidation, merger, sale or conveyance. The foregoing provision shall similarly apply to successive transactions of a similar nature by any such successor or purchaser.
  2
  Without limiting the generality of the foregoing, the anti-dilution provisions of this Section shall apply to such securities of such successor or purchaser after any such consolidation, merger, sale or conveyance.
  B.           Reclassification, etc. If the Borrower at any time shall, by reclassification or therwise, change the Common Stock into the same or a different number of securities of any class or classes that may be issued or outstanding, this Note, as to the unpaid principal portion thereof and accrued interest thereon, shall thereafter be deemed to evidence the right to purchase an adjusted number of such securities and kind of securities as would have been issuable as the result of such change with respect to the Common Stock immediately prior to such reclassification or other change.
  C.           Stock Splits, and Combinations. If the shares of Common Stock are subdivided or ombined into a greater or smaller number of shares of Common Stock, the Conversion Price shall be proportionately reduced in case of subdivision of shares or stock dividend or proportionately increased in the case of combination of shares, in each such case by the ratio which the total number of shares of Common Stock outstanding immediately after such event bears to the total number of shares of Common Stock outstanding immediately prior to such event.
  (e) During the period the conversion right exists, Borrower will reserve from its authorized and issued Common Stock not less than the number of shares of Common Stock issuable upon the full conversion of this Note. Borrower represents that upon issuance, such shares will be duly and validly issued, fully paid and non-assessable. Borrower agrees that its issuance of this Note shall constitute full authority to its officers, agents, and transfer agents who are charged with the duty of executing and issuing stock certificates to execute and issue the necessary certificates for shares of Common Stock upon the conversion of this Note.
  2.2Method of Conversion. This Note may be converted by the Holder in whole or in part as described in Section 2.1(a) hereof and subject to Section 2.3 hereof. Upon partial conversion of this Note, a new Note containing the same date and provisions of this Note shall, at the request of the Holder, be issued by the Borrower to the Holder for the principal balance of this Note and interest which shall not have been converted or paid.
