- 4 -

3.2 Exercise of Conversion Privilege: In order to exercise the conversion privilege, the Holder shall surrender this Debenture to the Company at the registered office of the Company in the City of Toronto, accompanied by written notice in the form of Schedule “B” hereto signed by the Holder stating that it elects to convert this Debenture or a stated portion of the Principal Sum thereof constituting $1,000 or an integral multiple of $1,000. The surrender of this Debenture, accompanied by such written notice, shall be deemed to constitute a contract between the Holder and the Company whereby (i) the Holder subscribes for the number of Common Shares which it shall be entitled to receive on such conversion, (ii) the Holder releases the Company from all liability under this Debenture or from all liability with respect to that portion of the Principal Sum to be converted, as the case may be, and (iii) the Company agrees that the release of liability constitutes full payment of the subscription price for the Common Shares issuable upon such conversion.

As promptly as practicable after the Conversion Date, the Company shall issue and delivered to the Holder a certificate in the name of the Holder for the number of Common Shares deliverable upon the conversion of such Debenture (or specified portion thereof). Such conversion shall be deemed to have been effected immediately prior to the close of business on the Conversion Date.

3.3 No Fractional Common Shares: Notwithstanding any other provision of this Debenture, the Company shall not be required to issue a fractional Common Share, or to pay any cash or other consideration in lieu of a fractional Common Share, upon the conversion of this Debenture. If any fractional Common Share would, except for the provisions of this Section, be deliverable upon the conversion of any Debenture, the number of Common Shares issuable to the Holder shall be rounded down to the next whole number of Common Shares.

3.4 Partial Exercise: The Holder may elect to convert less than all the Principal Sum into Common Shares, in which case the Holder shall be entitled to receive, without charge, a new certificate representing the balance of the Principal Sum.

3.5 Exercise During Legend Period: If the Holder elects to convert all or part of this Debenture prior to the expiry of the hold period referred to in the legend on the face page of this certificate, the Common Shares issuable on such exercise shall bear the same legend as on the face page of this certificate.

3.6 Transfer of Debenture: This Debenture may be transferred by the Holder (subject to limitations imposed by applicable securities laws and the rules of any stock exchange on which the Common Shares are listed for trading), provided that on or before the transfer of this Debenture all necessary notices and other documents with respect to the transfer of the Debenture shall have been filed by the Holder with the applicable securities regulatory authorities. The transferee shall be entitled to become a registered holder of the Debenture, and to receive a new certificate registered in the transferee’s name for that portion of the Principal Sum transferred to the transferee, upon delivery of each of the following (collectively, the “Transfer Documents”) to the address of the Company:

	(a)	this Debenture;
	(b)	a completed transfer in the form attached to this certificate as Schedule “C”, signed by the Holder.

The Company shall be entitled to rely upon delivery of the Transfer Documents as sufficient evidence that there has been compliance with applicable securities laws and stock exchange requirements, or the Company may require evidence of compliance with applicable securities laws and stock exchange requirements.

Any delivery of Transfer Documents made after 4:00 p.m. shall be deemed to have been received on the next Business Day. The transfer of all or part of this Debenture shall be recorded in the register maintained by the Company as of the close of business on the date on which the Transfer Documents are received by the Company. A certificate for the transferred portion of the Debenture shall be delivered to the transferee (and if the transferred portion of the Debenture represent less than all of the Principal Sum, a certificate for the balance of this Debenture shall be delivered to the Holder) within a reasonable time.

3.7 Ownership of Debenture: The Company shall treat the registered owner of this Debenture as the absolute owner thereof for all purposes, and the Company shall not be affected by any notice or knowledge to the contrary except where the Company is required to take notice by statute or by order of a court of competent jurisdiction. The issue by the Company of the Common Shares (and/or any other securities or assets pursuant to ARTICLE 4) upon the conversion of all or part of the Debenture by the Holder, shall discharge all responsibilities of the Company with respect to the portion of the Debenture so exercised and the Company shall not be bound to inquire into the title of the Holder except where the Company is required to take notice by statute or by order of a court of competent jurisdiction.

- 5 -

3.8 Not a Shareholder: Nothing in this certificate shall be construed as conferring upon the Holder any right or interest whatsoever as a shareholder of the Company.

3.9 Lost Certificate: If this certificate becomes stolen, lost, mutilated or destroyed, the Company may, on such terms as it in its discretion imposes (including the requirement to provide a bond of indemnity), issue a new certificate of like denomination, tenure and date as this certificate.

3.10 Register of the Debenture: The Company will keep, at its principal office, a register of the names and addresses of the holders of this Debenture and any other debentures in this series and particulars of the debenture held by them.

ARTICLE 4 ADJUSTMENTS

4.1 Adjustment to Conversion Price: The Conversion Price in effect at any time is subject to adjustment from time to time in the events and in the manner provided in this Article 4.

4.2 Share Reorganization: Whenever during the Conversion Period the Company:

	(a)	issues Common Shares to all or substantially all the holders of the Common Shares by way of a stock dividend or other distribution (other than dividends paid in the ordinary course); or
	(b)	subdivides, redivides or changes its outstanding Common Shares into a greater number of shares; or
	(c)	combines, consolidates or reduces its outstanding Common Shares into a smaller number of shares,

(any of those events being a “Share Reorganization”), the Conversion Price will be adjusted effective immediately after the record date at which the holders of Common Shares are determined for the purposes of the Share Reorganization to a number that is the product of (1) the Conversion Price in effect on the record date and (2) a fraction:

	(d)	the numerator of which is the number of outstanding Common Shares, calculated as of the record date before giving effect to the Share Reorganization; and
	(e)	the denominator of which is the number of outstanding Common Shares, calculated as of the record date after giving effect to the Share Reorganization.

4.3 Rights Offering: Whenever during the Conversion Period the Company issues rights, options or warrants to all or substantially all the holders of the Common Shares pursuant to which those holders are entitled to subscribe for, purchase or otherwise acquire Common Shares or Convertible Securities within a period of 45 days from the date of issue (the “Rights Period”) at a price, or at a conversion price, of less than 90% of the Current Market Price at the record date for such distribution (any such issuance being a “Rights Offering” and Common Shares that may be acquired in exercise of the Rights Offering, or upon conversion of the Convertible Securities offered by the Rights Offering, being the “Offered Shares”), the Conversion Price will be adjusted effective immediately after the record date at which holders of Common Shares are determined for the purposes of the Rights Offering to a number that is the product of (1) the Conversion Price in effect on the record date, and (2) a fraction:

- 6 -

	(a)	the numerator of which is the sum of:
		(i)	the number of Common Shares outstanding on the record date, before giving effect to the Rights Offering; and
		(ii)	the number arrived at when either the product of:
			(A)	the number of Offered Shares offered and the price at which those shares are offered; or
			(B)	the conversion price of the Offered Shares and the maximum number of Offered Shares for or into which the Convertible Securities offered pursuant to the Rights Offering may be converted,
			as the case may be, is divided by the Current Market Price of the Common Shares on the record date; and
	(b)	the denominator of which is the sum of:
		(i)	the number of Common Shares outstanding on the record date, before giving effect to the Rights Offering; and
		(ii)	the number of Offered Shares offered pursuant to the Rights Offering or the maximum number of Offered Shares into which the Convertible Securities offered pursuant to the Rights Offering may be converted, as the case may be.

If all the Offered Shares are not issued, the Conversion Price will be readjusted based upon the number of Offered Shares actually issued.

4.4 Special Distribution: Whenever during the Conversion Period the Company issues or distributes to all or substantially all the holders of Common Shares (other than as a Share Reorganization, a Rights Offering or dividends paid in the ordinary course):

	(a)	shares of any class;
	(b)	rights, options or warrants;
	(c)	evidences of indebtedness; or
	(d)	any other assets including shares of other corporations,

(any of those issuances or distributions being a “Special Distribution”), the Conversion Price will be adjusted effective immediately after the record date at which the holders of Common Shares are determined for purposes of the Special Distribution to an Conversion Price that is the product of (1) the Conversion Price in effect on the record date, and (2) a fraction:

	(e)	the numerator of which is the amount determined under Section 4.4(f), less the aggregate fair market value, as determined by the board (whose determination, absent manifest error, will be conclusive), of the shares, rights, options, warrants, evidences of indebtedness or other assets issued or distributed in the Special Distribution; and
	(f)	the denominator of which is the product of:

(i) the number of Common Shares outstanding on the record date, and

- 7 -

(ii) the Current Market Price thereof on that date.

To the extent that the distribution of shares, rights, options, warrants, evidences of indebtedness or assets is not made or to the extent that any rights, options or warrants expire without being exercised, the Conversion Price will be readjusted to the Conversion Price that would then be in effect based upon shares, rights, options, warrants, evidences of indebtedness or assets actually distributed or based upon the number of securities actually delivered upon the exercise of the rights, options or warrants, as the case may be.

4.5 Reclassification of Common Shares: If the Company reclassifies or otherwise changes the outstanding Common Shares, the right to purchase Common Shares evidenced by this certificate will be adjusted effective immediately upon the reclassification becoming effective so that the Holder if converting this Debenture thereafter will be entitled to receive such property as the Holder would have received had the Debenture been converted immediately prior to the effective date of the reclassification.

4.6 Redemption on Capital Reorganization and Certain Other Events: Whenever during the Conversion Period there is a reorganization of the Company not otherwise provided for in Sections 4.2, 4.3, 4.4 or 4.5 or a consolidation or merger or amalgamation of the Company with or into another body corporate or other entity (including a transaction whereby all or substantially all of the Company’s undertaking and assets become the property of any other body corporate, trust, partnership or other entity), a sale of all or substantially all of the assets of the Company, or the Company receiving conditional listing approval for the listing of the Company’s Common Shares on any of the TSX, the TSX Venture, the AMEX, the AIM, or the NASDAQ Stock Exchange (and the Company holding a bona fide intention to so list), the Company may redeem the Debenture at its option on not less than fifteen (15) business days’ notice (during which period the Holder may convert the Debenture at its sole option), at the following rates:

(i) $1,250 per $1,000 of Principal Sum, if occurring on or before the first anniversary of issuance;

(ii) $1,125 per $1,000 of Principal Sum if occurring after the first anniversary and prior to the second anniversary of issuance; and

(iii) $1,050 per $1,000 of Principal Sum if occurring after the second anniversary of issuance and prior to the end of the term.

4.7 Rules Regarding Calculation of Adjustment of Conversion Price

	(a)	The adjustments and readjustments provided for in this ARTICLE 4 are cumulative and, subject to subsection 4.7(b), will apply (without duplication) to successive issues, subdivisions, combinations, consolidations, distributions and any other events that require adjustment of the Conversion Price or the number or kind of shares or securities to be issued upon conversion of this Debenture.
	(b)	No adjustment in the Conversion Price will be required unless the adjustment would result in a change of at least 1% in the Conversion Price then in effect provided however, that any adjustments that, except for the provisions of this subsection 4.7(b) would otherwise have been required to be made, will be carried forward and taken into account in any subsequent adjustment.
	(c)	No adjustment in the Conversion Price will be made in respect of any event described in subsections 4.2(a), 4.3 or 4.4 if the Holder is entitled to participate in the event as if the Holder had converted this Debenture immediately prior to the effective date or record date of the event.
	(d)	No adjustment in the Conversion Price will be made pursuant to this ARTICLE 4 in respect of Common Shares issued or issuable from time to time as dividends paid in the ordinary course.

- 8 -

	(e)	If a dispute arises with respect to adjustments of the Conversion Price, the dispute will be conclusively determined by the Company’s auditors or, if they are unable or unwilling to act, by such firm of independent chartered accountants as may be selected by the directors of the Company and any such determination, absent manifest error, will be binding upon the Company and the Holder.
	(f)	If the Company sets a record date to determine the holders of Common Shares for the purpose of entitling them to receive any dividend or distribution or any subscription or purchase rights and thereafter abandons its plans to pay or deliver the dividend, distribution or subscription or purchase rights then no adjustment in the Conversion Price will be required by reason of the setting of the record date.
