- 5 -

5.2 Mechanics and Effect of Conversion

	(a)	If Large Scale wishes to convert the entire Principal Amount into Common Shares at any time, Large Scale shall duly endorse and surrender this Note to the Company during usual business hours at its principal place of business in Vancouver, British Columbia with written notice to the Company, duly executed by Large Scale or its duly appointed attorney, stating that Large Scale elects to convert the Principal Amount into Common Shares and specifying the name or names (with addresses) in which a certificate or certificates for Common Shares are to be issued. This Note shall thereafter be cancelled by the Company. Upon surrender of the Note, Large Scale shall be entitled to be entered as a shareholder on the books and records of the Company as at the date of surrender. Immediately after the surrender of the Note (but in any case no later than five (5) Business Days from the date of surrender), the Company shall deliver to Large Scale (or its duly appointed attorney) a certificate or certificates, with appropriate legends, representing the number of fully paid and non-assessable Common Shares resulting from the conversion.
	(b)	If Large Scale desires to convert only a portion of the Principal Amount of the Note, it shall duly endorse and surrender the Note to the Company and comply with the other procedures described in (a) above, with written notice indicating what portion of the Principal Amount is to be converted by the Company into Common Shares. The Company, at its expense, shall issue to Large Scale the number of Common Shares to which Large Scale is entitled upon conversion and shall issue to Large Scale a replacement convertible unsecured promissory note representing the same continuing indebtedness as the Note it replaced and having identical terms to this Note, except that the principal amount thereof shall equal the difference between (x) the Principal Amount outstanding immediately prior to such conversion less (y) the portion of such Principal Amount so converted into Common Shares. Partial conversion of the Principal Amount shall occur in multiples of one thousand dollars ($1,000).
	(c)	No fractional Common Shares shall be issued upon conversion of this Note (or any portion thereof). In lieu of the Company issuing a fractional Common Share, the Company shall round such fractional Common Share down to the nearest whole Common Share. Large Scale shall not be entitled to any compensation in respect of any fractional Common Share.

5.3 Reservation of Common Shares Issuable Upon Conversion

The Company shall at all times while this Note remains outstanding reserve and keep available out of its authorized but unissued Common Shares, solely for the purpose of effecting the conversion of this Note (and any Note issued in cancellation thereof) such number of Common Shares as shall from time to time be sufficient to effect the conversion of this Note, and if at any time the number of authorized but unissued Common Shares shall not be sufficient to effect the conversion of this Note, the Company will take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued Common Shares to such number of shares as shall be sufficient for such purpose. All Common Shares which shall be so issuable shall be duly and validly issued as fully paid and non-assessable and listed on the TSX.

- 6 -

ARTICLE 6
CONVERSION PRICE ADJUSTMENTS

6.1 Anti-Dilution Adjustments

The Conversion Price and the number and type of securities to be received upon conversion of the Principal Amount shall be subject to adjustment from time to time as follows:

	(a)	Dividend, Subdivision, Combination or Re-Classification of Common Shares
		If the Company shall at any time or from time to time, before the complete conversion of this Note:

	(i)	pay a dividend or make a distribution on the outstanding Common Shares payable in shares of the Company;
	(ii)	subdivide the outstanding Common Shares into a larger number of shares;
	(iii)	split or combine the outstanding Common Shares into a smaller number of shares; or
	(iv)	reclassify its Common Shares,

then, and in each such case, the Conversion Price in effect three (3) Business Days prior to the record date for such event shall be adjusted (and any other appropriate actions shall be taken by the Company, including in the case of (i),(ii) or (iii), a corresponding change in the number of Common Shares) so that Large Scale shall be entitled to receive the number of Common Shares or other securities of the Company that it would have owned or would have been entitled to receive upon or by reason of any of the events described above, had the entire Principal Amount been converted immediately prior to the occurrence of such event. An adjustment made pursuant to this Section 6.1(a) shall become effective retroactively:

	(v)	in the case of any such dividend or distribution, to a date immediately following the close of business on the record date for the determination of holders of Common Shares entitled to receive such dividend or distribution; or
	(vi)	in the case of any such subdivision, split, combination or re- classification, to the close of business on the Business Day upon which such corporate action becomes effective.

- 7 -

Such adjustments shall be made successively whenever any event listed in this Section 6.1(a) shall occur.

	(b)	Certain Distributions
		If the Company shall at any time or from time to time, prior to conversion of the entire Principal Amount, distribute to holders of Common Shares (including any such distribution made in connection with a merger, amalgamation, reorganization, arrangement or consolidation in which the Company is the resulting or surviving Person) any (i) cash, (ii) evidence of indebtedness of the Company or another issuer, (iii) securities of the Company or another issuer or (iv) other assets (excluding dividends payable in Common Shares for which adjustment is made under Section 6.1(a) or rights or warrants to subscribe for or purchase any of the foregoing, then, and in each such case, the Conversion Price then in effect shall be adjusted (and any other appropriate actions shall be taken by the Company) by multiplying the Conversion Price in effect three (3) Business Days prior to the date of such distribution by a fraction:

	(i)	the numerator of which shall be the Market Price for the period starting two (2) Business Days prior to the record date for such distribution; and
	(ii)	the denominator of which shall be the Market Price for the period ending three (3) Business Days prior to the record date for the distribution (but such fraction shall not be greater than one).

	(c)	Rights Offering.
		If at any time the Company fixes a record date for the issue or distribution of rights, options or warrants to the holders of all or substantially all of the outstanding Common Shares under which such holders are entitled to subscribe for or purchase Common Shares or securities exchangeable for or convertible into Common Shares at a price per share (or having an exchange price or conversion price per share) of less than 95% of the Market Price of the Common Shares on such record date (any of such events being a "Rights Offering"), then the Conversion Price will be adjusted effective immediately after the record date for the Rights Offering to a price determined by multiplying the Conversion Price in effect on such record date by a fraction:

(i) the numerator of which will be the aggregate of:

	(A)	the number of Common Shares outstanding as of the record date for the Rights Offering; and
	(B)	a number determined by dividing the sum of:

- 8 -

	(i)	the product of the number of Common Shares (or securities exchangeable for or convertible into Common Shares) offered under the Rights Offering and the price at which such Common Shares are offered (or the exchange price or conversion price per share), and
	(ii)	the product of the number of Common Shares, if any, issuable upon exercise of any securities exchangeable for or convertible into Common Shares (the "Compensation Securities") which Compensation Securities may be issued as compensation to one or more guarantors under the Rights Offering and the exchange price or conversion price per Common Share of such Compensation Securities, as the case may be,

by the Market Price of the Common Shares as of the record date for the Rights Offering; and

(ii) the denominator of which will be the aggregate of the number of Common Shares outstanding on such record date, the number of Common Shares (or securities exchangeable for or convertible into Common Shares) offered pursuant to the Rights Offering and the number of Common Shares issuable on the exchange or conversion of any Compensation Securities.

Any Common Shares owned by or held for the account of the Company will be deemed not to be outstanding for the purpose of any such calculation. For greater certainty and notwithstanding anything to the contrary contained herein, the Conversion Price shall not be adjusted pursuant to this Section 6.1(c) in circumstances where the Market Price of the Common Shares as of the record date for the Rights Offering and the issue price under the Rights Offering is greater than the Conversion Price. To the extent that a Rights Offering is not completed or any rights, options or warrants are not exercised prior to the expiration of a Rights Offering, the Conversion Price shall then be readjusted to the Conversion Price which would then be in effect if such record date had not been fixed or if such expired rights, options or warrants had not been issued.

	(d)	Capital Reorganizations
		If at any time or from time to time after the Issue Date there is a capital reorganization of the Common Shares (other than as previously described in this Article 6), then, as a part of such capital reorganization provision shall be made so that Large Scale shall thereafter be entitled to receive, upon conversion of this Note, the number of shares or other securities or property of the Company to which a holder of the number of Common Shares deliverable upon such conversion would have been entitled on such capital reorganization, subject to adjustment in respect of such securities by the terms thereof. In any such case, appropriate adjustment shall be made in the application of the provisions of this Article 6 with respect to the rights of Large Scale after such capital reorganization to the end that the provisions of this Article 6 (including adjustment of the Conversion Price then in effect and the number of shares issuable upon conversion of this Note) shall be applicable after that event and be as nearly equivalent as practicable.

- 9 -

6.2 Adjustments to Conversion Price for Private Placement of Additional Shares

	(a)	No Adjustment of Conversion Price. For greater certainty and notwithstanding anything to the contrary contained herein, the Conversion Price shall not be adjusted pursuant to this Section 6.2 in circumstances where the Market Price of the Common Shares at the time of issuance or deemed issuance of Additional Shares and the issue price of such Additional Shares is greater than the Conversion Price. In addition, no adjustment in the Conversion Price shall be made as the result of the issuance or deemed issuance of Additional Shares if the Company receives written consent from Large Scale confirming that no adjustment be made as the result of the issuance or deemed issuance of such Additional Shares.
	(b)	Deemed Issue of Additional Shares.

	(i)	If the Company at any time or from time to time after the Issue Date issues, pursuant to a private placement exemption under Canadian Securities Laws, Options or Convertible Securities (excluding Options or Convertible Securities that are themselves Exempted Securities), then the maximum number of Common Shares (as set forth in the relating instrument, assuming the satisfaction of any conditions to exercisability, convertibility or exchangeability but without regard to any of its provisions for a subsequent adjustment of such number) issuable upon the exercise of such Options or, in the case of Convertible Securities, the conversion or exchange of such Convertible Securities, will be deemed to be Additional Shares issued as of the time of such issue.
	(ii)	If the terms of any Option or Convertible Security, the issuance of which resulted in an adjustment to the Conversion Price, are revised as a result of an amendment to such terms or any other adjustment under such Option or Convertible Security (but excluding automatic adjustments to such terms under anti-dilution or similar provisions of such Option or Convertible Security) to provide for either (1) any increase or decrease in the number of Common Shares issuable upon the exercise, conversion and/or exchange of the Option or Convertible Security or (2) any increase or decrease in the consideration payable to the Company upon such exercise, conversion and/or exchange, then, effective upon such increase or decrease becoming effective, the Conversion Price computed upon the original issue of the Option or Convertible Security (or upon the occurrence of a record date with respect thereto) shall be readjusted to such Conversion Price as would have obtained had such revised terms been in effect upon the original date of issuance of the Option or Convertible Security. Notwithstanding the foregoing, no readjustment under this clause (b) shall increase the Conversion Price to an amount that exceeds the lower of (i) the Conversion Price in effect immediately before the original adjustment made as a result of the issuance of the Option or Convertible Security, or (ii) the Conversion Price that would have resulted from any issuances of Additional Shares (other than deemed issuances of Additional Shares as a result of the issuance of the Option or Convertible Security) between the original adjustment date and such readjustment date.

	(iii)	If the terms of any Option or Convertible Security (excluding Options or Convertible Securities that are themselves Exempted Securities), the issuance of which did not result in an adjustment to the Conversion Price under 6.2(b)(ii) (either because the consideration per share of the Additional Shares subject thereto was equal to or greater than the Conversion Price then in effect, or because such Option or Convertible Security was issued before the Issue Date), are revised after the Issue Date as a result of an amendment to such terms or any other adjustment under such Option or Convertible Security (but excluding automatic adjustments to such terms under anti-dilution or similar provisions of the Option or Convertible Security) to provide for either (1) any increase in the number of Common Shares issuable upon the exercise, conversion or exchange of the Option or Convertible Security or (2) any decrease in the consideration payable to the Company upon such exercise, conversion or exchange, then the Conversion Price computed upon the adjustment of the Option or Convertible Security (or upon the occurrence of a record date with respect thereto) shall be readjusted to such Conversion Price as would have obtained had such revised terms been in effect upon the original date of issuance of the Option or Convertible Security.
	(iv)	Upon the expiration or termination of any unexercised Option or unconverted or unexchanged Convertible Security (or portion thereof) that resulted (either upon its original issuance or upon a revision of its terms) in an adjustment to the Conversion Price, the Conversion Price shall be readjusted to such Conversion Price as would have obtained had such Option or Convertible Security (or portion thereof) never been issued.
	(v)	If the number of Common Shares issuable upon the exercise, conversion and/or exchange of any Option or Convertible Security, or the consideration payable to the Company upon such exercise, conversion and/or exchange, is calculable at the time the Option or Convertible Security is issued or amended but is subject to adjustment based upon subsequent events, any adjustment to the Conversion Price shall be effected at the time of such issuance or amendment based on such number of shares or amount of consideration without regard to any provisions for subsequent adjustments. If the number of Common Shares issuable upon the exercise, conversion and/or exchange of any Option or Convertible Security, or the consideration payable to the Company upon such exercise, conversion and/or exchange, cannot be calculated at all at the time the Option or Convertible Security is issued or amended, any adjustment to the Conversion Price that would result at the time of such issuance or amendment shall instead be effected at the time such number of shares and/or amount of consideration is first calculable (even if subject to subsequent adjustments), assuming for purposes of calculating such adjustment to the Conversion Price that such issuance or amendment took place at the time such calculation can first be made.

- 11 -

	(c)	Adjustment of Conversion Price Upon Issuance of Additional Shares. If the Company, at any time after the Issue Date issues Additional Shares pursuant to a private placement exemption under Canadian Securities Laws, without consideration or for consideration per share less than the Initial Market Price, then the Conversion Price shall be reduced, concurrently with such issue, to 124% of the consideration per share received by the Company for such issue or deemed issue of the Additional Shares; provided that if such issuance or deemed issuance was without consideration, then the Company will be deemed to have received an aggregate of $.001 of consideration for all such Additional Shares issued or deemed to be issued. In no circumstances will the Conversion Price be reduced to less than 85% of the Initial Market Price under this section 6.2(c).
	(d)	Determination of Consideration. For purposes of this subsection, the consideration received by the Company for the issue of any Additional Shares shall be computed as follows:

(i) Cash and Property: Such consideration shall:

	(A)	if it consists of cash, be computed at the aggregate amount of cash received by the Company;
	(B)	if it consists of property other than cash, be computed at its fair market value at the time of such issue, as determined in good faith by the Company's board of directors; and
	(C)	if Additional Shares are issued together with other shares or securities or other assets of the Company for consideration that covers both, be the proportion of such consideration so received, computed as provided in clauses (A) and (B) above, as determined in good faith by the Company's board of directors.

- 12 -

(ii) Options and Convertible Securities. The consideration per share received by the Company for Additional Shares deemed to have been issued, relating to Options and Convertible Securities, shall be determined by dividing:

	(A)	the total amount, if any, received or receivable by the Company as consideration for the issue of such Options or Convertible Securities, plus the minimum aggregate amount of additional consideration (as set forth in the relating instruments, without regard to any of its provision for a subsequent adjustment of such consideration) payable to the Company upon the exercise of the Options or the conversion or exchange of the Convertible Securities, or in the case of Options for Convertible Securities, the exercise of the Options for Convertible Securities and the conversion or exchange of such Convertible Securities, by
	(B)	the maximum number of Common Shares (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities.

(e) Multiple Closing Dates. If the Company issues on more than one date Additional Shares that are a part of one transaction or a series of related transactions and that would result in an adjustment to the Conversion Price, and such issuance dates occur within a period of no more than 90 days from the first such issuance to the final such issuance, then, upon the final such issuance, the Conversion Price shall be readjusted to give effect to all such issuances as if they occurred on the date of the first such issuance (and without giving effect to any additional adjustments as a result of any such subsequent issuances within such period).

6.3 Certificate of Adjustment

In each case of an adjustment or re-adjustment of any Conversion Price, the Company, at its own expense, shall cause its Chief Financial Officer to compute such adjustment or readjustment in accordance with the provisions hereof and prepare a certificate showing such adjustment or re-adjustment, and shall mail such certificate, by first class mail, to Large Scale at Large Scale's address as shown in the Company's books within 10 Business Days from the date of adjustment or readjustment. The certificate shall set forth such adjustment or re-adjustment, showing in detail the facts upon which such adjustment or re-adjustment is based.
