(b)        Conversion Price. Subject to adjustment from time to time as provided in Section 4(d) below, the term “Conversion Price" shall mean US$0.03 per share of Common Stock and the rate of exchange for CDN dollar denominated notes shall be determined on the date of conversion.

(i) Adjustments for Stock Splits and Combinations. If the Company shall at any time or from time to time after the Issuance Date, effect a stock split of the outstanding Common Stock, the Conversion Price in effect immediately prior to the stock split shall be proportionately decreased. If the Company shall at any time or from time to time after the Issuance Date, combine the outstanding shares of Common Stock, the Conversion Price in effect immediately prior to the combination shall be proportionately increased. Any adjustments under this Section 4(c)(i) shall be effective at the close of business on the date the stock split or combination occurs.

(ii) Adjustments for Certain Dividends and Distributions. If the Company shall at any time or from time after the Issuance Date, make or issue or set a record date for the determination of holders of Common Stock entitled to receive a dividend or other distribution payable in shares of Common Stock, then, and in each event, the Conversion Price in effect immediately prior to such event shall be decreased as of the time of such issuance or, in the event such a record date shall have been fixed, as of the close of business on such record date, by multiplying the Conversion Price then in effect by a fraction;

(B) the denominator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of shares of Common Stock issuable in payment of such dividend or distribution.

(iii) Adjustments for Other Dividends and Distributions. If the Company shall at any time or from time to time after the Issuance Date, make or issue or set a record date for the determination of holders of Common Stock entitled to receive a dividend or other distribution payable in other than shares of Common Stock, then, and in each event, an appropriate revision to the Conversion Price shall be made and provision shall be made (by adjustments of the Conversion Price or otherwise) so that the holder of this Note shall receive upon conversions thereof, in addition to the number of shares of Common Stock receivable thereon, the number of securities of the Company which they would have received had this Note been converted into Common Stock on the date of such event and had thereafter, during the period from the date of such event to and including the Conversion Date, retained such securities (together with any distributions payable thereon during such period), giving application to all adjustments called for during such period under this Section 4(c)(iii) with respect to the rights of the holders of the Note.

(iv) Adjustments for Reclassification, Exchange, or Substitution. If the Common Stock issuable upon conversion of this Note at any time or from time to time after the Issuance Date shall be changed into the same or a different number of shares of any class or classes of stock, whether by reclassification, exchange, substitution or otherwise (other than by way of a stock split or combination of shares or stock dividends provided for in Sections 4(c)(i), (ii) and (iii), or a reorganization, merger, consolidation, or sale of assets provided for in Section 4(c)(v)), then, and in each event, an appropriate revision to the Conversion Price shall by made and provisions shall be made (by adjustments of the Conversion Price of otherwise) so that the holder of this Note shall have the right thereafter to convert such Note into the kind and amount of shares of stock and other securities receivable upon such reclassification, exchange, substitution or other change, by holders of the number of shares of Common Stock into which such Note might have been converted immediately prior to such reclassification, exchange, substitution or other change, all subject to further adjustment as provided herein.

(v) Adjustments for Reorganization, Merger, Consolidation, or Sales of Assets. If at any time or from time to time after the Issuance Date there shall be a capital reorganization of the Company (other than by way of a stock split or combination of shares or stock dividends or distributions provided for in Section 4(c)(i), (ii) and (iii), or a reclassification, exchange or substitution of shares provided for in Section 4(c)(iv)), or a merger or consolidation of the Company with or into another corporation, or the sale of all or substantially all of the Company's properties or assets to any other person, then as a part of such reorganization, merger, consolidation, or sale, an appropriate revision to the Conversion Price shall be made and provision shall be made (by adjustments of the Conversion Price or otherwise) so that the holder of this Note shall have the right thereafter to convert this Note into the kind and amount of shares of stock and other securities or property of the Company or any successor corporation resulting from such reorganization, merger, consolidation, or sale, to which a holder of Common Stock deliverable upon conversion of such shares would have been entitled upon such reorganization, merger, consolidation, or sale. In any such case, appropriate adjustment shall be made in the application of the provisions of this Section 4(c)(v) with respect to the rights of the holders of this Note after the reorganization, merger, consolidation, or sale to the end that the provisions of this Section 4(c)(v) (including any adjustment in the Conversion Price then in effect and the number of shares of stock or other securities deliverable upon conversion of this Note) shall be applied after that event in as nearly an equivalent manner as may be practicable.

(c)       No Impediment. The Company shall not, by amendment of its Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, but will at all times in good faith, assist in the carrying out of all the provisions of this Section 4 and in the taking of all such action as may be necessary or appropriate in order to protect the conversion rights of the holders of the Note set forth in this Section 4 against impairment.

Notwithstanding the foregoing, the Company shall not be obligated to deliver a certificate unless such certificate would reflect an increase or decrease of at least one percent (1%) of such adjusted amount.

(e)        In the event that, notwithstanding the provisions of this Section 9, any payment shall be made on account of the principal of or interest on this Note in contravention of such provisions, then such payment shall be held for the benefit of, and shall be paid over and delivered to, the holders of such Senior Debt remaining unpaid to the extent necessary to pay in full in cash or cash equivalents the principal of and interest on such Senior Debt in accordance with its terms after giving effect to any concurrent payment or distribution to the holders of such Senior Debt.

The Company may pay the holder hereof any defaulted payment and all other amounts due following any such acceleration of the maturity of this Note if this Section 9 would not prohibit such payment to be made at that time.

(h)        Upon payment in full of all Senior Debt, the Payee of this Note shall be subrogated to the rights of the holder or holders of Senior Debt to receive all payments or distributions applicable on such Senior Debt to the extent of the prior application thereto of moneys or other assets which would have been received in respect of this Note, but for these subordination provisions, until the principal of, and interest on, this Note shall have been paid in full.

(i)        The Payee, by accepting this Note:

(i) shall be bound by all of the foregoing subordination provisions;

(a)        the payment terms set forth in Section l of this Note;

(b)        the subordination provisions contained in Section 9 of this Note, nor
