CONVERSION AND PURCHASE RIGHTS

2.1 Conversion or Purchase Right. Holder shall have the right from and after the date of execution of this Debenture, and then at any time on or prior to February 26, 2009, to convert all or any portion of the principal indebtedness evidenced by the provisions of this Debenture into fully paid and nonassessable shares of $.001 par value common stock of Borrower (“Common Stock”) on the terms and subject to the conditions specified by the provisions of this Article Two of this Debenture. Upon the surrender of this Debenture, accompanied by ▇▇▇▇▇▇’s written request for conversion as provided for in Section 2.3 of this Debenture, Borrower shall pay Holder within 30 days of that written request for conversion all interest accrued on the unpaid principal indebtedness evidenced by the provisions of this Debenture to the date of conversion and issue and deliver to Holder certificates evidencing the appropriate number of shares of Common Stock as determined in accordance with Section 2.3 of this Debenture. If a portion but less than all of such principal is converted, Borrower shall deliver to Holder a certificate for the proper number of shares of Common Stock for the portion of that principal indebtedness converted and a new Debenture in the form hereof for the unconverted balance of the principal indebtedness evidenced by the provisions of this Debenture.

2.2 Conversion or Purchase Price. Subject to adjustment as specified by the provisions of Section 2.4 of this Debenture, for that period commencing on the date of execution of this Debenture, and continuing through and including February 26, 2009, the conversion or purchase price of the Common Stock indebtedness shall be CDN$0.10 per share (“Conversion Price”).

2.3 Mechanics of Conversion. No fractional shares of Common Stock shall be issued upon any conversion of the principal indebtedness evidenced by the provisions of this Debenture. In lieu of any fractional shares to which Holder would otherwise be entitled, Borrower shall pay Holder cash in the amount equal to the Conversion Price for such fractional shares. Before Holder shall be entitled to convert the indebtedness evidenced by the provisions of this Debenture into shares of Common Stock and to receive certificates therefor, Holder shall surrender the original copy of this Debenture, duly endorsed and cancelled, at the office of Borrower, and shall give at least seventy-six (76) days written notice to Borrower at such office that Holder elects to so convert the principal indebtedness evidenced by the provisions of this Debenture, which date shall be the conversion date (“Conversion Date”); and provided, further, however, that Borrower shall not be obligated to issue certificates evidencing the shares of Common Stock issuable unless the original endorsed and cancelled original copy of this Debenture is either delivered to Borrower, as specified above, or Holder notifies Borrower that such original copy of this Debenture has been lost, stolen or destroyed and executes an agreement to indemnify Borrower from any loss incurred by Borrower in connection with such original copy of this Debenture. Borrower shall, as soon as practicable after such delivery of an original copy of this Debenture, or such agreement and indemnification, issue and deliver or cause to be issued and delivered at such office to Holder, a certificate or certificates for the number of shares of Common Stock to which Holder shall be entitled and a check payable to Holder in the amount of any cash amounts payable as a result of the conversion into fractional shares of Common Stock. The person or persons entitled to receive the shares of Common Stock issuable upon any such conversion shall be treated for all purposes as the record holder or holders of such shares of Common Stock on such date.

2.4 Adjustment of Conversion Terms. The Conversion Price and number of shares of Common Stock to be issued upon conversion or purchase shall be subject to adjustment from time to time upon the

2

happening of certain events while the conversion or purchase right specified by the provisions of this Debenture remains outstanding, as follows:

▇. ▇▇▇▇▇▇, Sale of Assets, etc. If Borrower at any time shall consolidate with or merge into or sell or convey all or substantially all its assets, the provisions of this Debenture shall thereafter evidence the right to purchase such number and type of 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. Without limiting the generality of the foregoing, the provisions of this Debenture shall apply to such securities of such successor or purchaser after any such consolidation, merger, sale or conveyance.

B. Reclassification, etc. If Borrower at any time shall, by subdivision, combination or reclassification of securities, or otherwise, change any of the securities then purchasable upon the exercise of the conversion or purchase right specified by the provisions of this Debenture into the same or a different number of securities of any class or classes, the provisions of this Debenture shall thereafter evidence the right to purchase such number and type of securities as would have been issuable as the result of such change with respect to the securities which were subject to such conversion or purchase right immediately prior to such subdivision, combination, reclassification or other change. If shares of Common Stock are subdivided or combined into a greater or smaller number of shares of Common Stock, the Conversion Price shall be proportionately decreased in case of subdivision of shares or proportionately increased in the case of combination of shares, in both situations by the ratio which the total number of shares of Common Stock to be outstanding immediately after the occurrence of such event bears to the total number of shares of Common Stock issued and outstanding immediately prior to the occurrence of such event.

2.5 Corporate Authority. ▇▇▇▇▇▇▇▇’s issuance of this Debenture shall constitute full authority to ▇▇▇▇▇▇▇▇'s officers who are charged with the duty of executing stock certificates for shares of Common Stock pursuant to the exercise of this Debenture by ▇▇▇▇▇▇. Borrower shall execute stock certificates for shares of Borrower’s Common Stock no later than thirty (30) days after the Conversion Date to convert the principal indebtedness evidenced by the provisions of this Debenture or purchase of shares pursuant to the provisions of this Debenture.

ARTICLE SEVEN

LOST OR DESTROYED DEBENTURES

7.1 Lost or Destroyed Debentures. Upon receipt by ▇▇▇▇▇▇▇▇ at its principal office of evidence satisfactory to Borrower of the loss, theft, destruction or mutilation of this Debenture, and in the event of any such loss, theft, or destruction, upon delivery of indemnity satisfactory to Borrower or, in case of any such mutilation, upon surrender and cancellation of this Debenture, Borrower will issue a new Debenture of similar tenor in lieu of this Debenture with a notification thereon of the date from which interest has accrued.

MAXIMUM INTEREST RATE

8.1 Maximum Interest Rate. The maximum total interest that Holder shall be entitled to receive pursuant to this Debenture shall not exceed the maximum rate permitted pursuant to applicable law. Borrower and Holder intend to comply at all times with applicable usury laws. Notwithstanding any provision of this Debenture, if at any time any applicable usury law would ever render usurious any amounts contemplated by this Debenture, it is Borrower’s and ▇▇▇▇▇▇'s express intention that Borrower shall not be required to pay interest pursuant to this Debenture at a rate in excess of the maximum lawful rate, that the provisions of this Section 8.1 of this Article Eight shall control any other inconsistent provisions of this Debenture, that such excess interest shall be immediately credited pursuant to the principal balance of this Debenture (or, if this Debenture has been fully paid, refunded by Holder to Borrower), and the provisions hereof shall be immediately reformed and the amounts thereafter collectible pursuant to this Debenture reduced, without the necessity of the execution of any further documents, so as to comply with the then applicable law, but so as to permit the recovery of the fullest amount otherwise called for pursuant to this Debenture. Any such crediting or refund shall not cure or

6

waive any default by Borrower pursuant to this Debenture. If at any time following any reduction in the interest rate payable by Borrower there remains unpaid any principal amount pursuant to this Debenture and the maximum interest rate allowed by applicable law is increased or eliminated, then the interest payable pursuant to this Debenture shall be readjusted, to the extent not prohibited by applicable law, so that the total dollar amount of interest payable pursuant to this Debenture shall be equal to the dollar amount of interest which would have been paid by Borrower without giving effect to the reduction in interest resulting from compliance with applicable usury laws. The term “applicable law” as used in this Debenture shall mean the laws of the State of Nevada, or federal law in the event that federal law preempts Nevada law.

ARTICLE NINE

CLOSING

9.1 Definition. The consummation of the transactions provided for herein (“Closing”) shall take place at the offices of Borrower, at 1:00 p.m. Pacific Standard Time, or at such other place and on such other date as shall be agree upon in writing by ▇▇▇▇▇▇▇▇ and Holder.

At the Closing, and provided Borrower has fully performed all its obligations pursuant to the provisions of this Debenture, Holder will deliver to Borrower a check (or wire transfer to Borrower’s account) made payable to the order of Borrower in the principal amount specified in the preamble of this Debenture.

ARTICLE TEN

INDEMNIFICATION

10.1 Indemnification.

A. Borrower will indemnify and hold harmless Holder, each of its directors, officers, shareholders, representatives, agents, accountants and attorneys, against any losses, claims, damages or liabilities to which Borrower or any such director, officer, shareholder, representative, agent, accountant or attorney may become subject, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) result from or are based upon any action known or unknown, which currently exists or may arise in the future as a direct or indirect result of this Debenture; and will reimburse any legal or other expenses reasonably incurred by Holder any such director, officer, shareholder, representative, agent, accountant or attorney in connection with investigating or defending any such loss, claim, damage, liability or action.

B. Promptly after receipt by Holder of notice of the commencement of any action, Holder will, if a claim in respect thereof is to be made against Holder pursuant to the provisions of this Section 10.1, notify Borrower of the commencement thereof; but the omission so to notify Borrower will not relieve Borrower from any liability which Borrower may have to Holder pursuant to the provisions of this Section 10.1.

C. In the event that any such action is brought against ▇▇▇▇▇▇, and ▇▇▇▇▇▇ notifies Borrower of the commencement thereof, Borrower will be entitled to participate in, and, to the extent that Borrower may desire, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to Holder. In the event ▇▇▇▇▇▇▇▇ gives notice to ▇▇▇▇▇▇ of ▇▇▇▇▇▇▇▇'s election so to assume the defense thereof, ▇▇▇▇▇▇▇▇ will not be liable to Holder pursuant to the provisions of this subparagraph C for any legal or other expenses subsequently incurred by ▇▇▇▇▇▇ in connection with the

7

defense thereof subsequent to the date of such notice, other than reasonable costs of investigation.
