B.      The Lender has agreed to extend the term of the Loan to January 12, 2009 on the terms and conditions set out herein.

NOW, THEREFORE, in consideration of the premises contained herein and the sum of $10.00 paid by the Borrower to the Lender, the receipt and sufficiency of which are hereby acknowledged, the parties agree to amend the terms of the Loan Agreement as follows:

1.	Definitions. Capitalized terms used in this Agreement shall have the same meaning as specified in the Loan Agreement unless the context clearly indicates the contrary.

	(i)	The term “Maturity Date” is replaced in its entirety with the following:
		“Maturity Date” means January 12, 2009;
	(ii)	Section 2.1 of the Loan Agreement is replaced in its entirety with the following:
		“2.1 “Loan and Repayment. The Lender hereby agrees to lend to the Borrower the Principal Sum of $250,000 (U.S.). The Loan shall be made in United States currency and shall be repaid by the Borrower on or before January 12, 2009.”
	(iii)	Section 7.1 of the Loan Agreement is replaced in its entirety with the following:
		“7.1 The Lender may at its option, at any time prior to January 12, 2009, convert all or any portion of the Principal Sum into that number of fully-paid and non-assessable shares of common stock of the Borrower (the “Conversion Shares”) as shall be equal to the Principal Sum at a conversion rate which shall be the lesser of $0.30 U.S. per share or the closing price of the Borrower’s shares on the Over-the-Counter Bulletin Board on the business day preceding the date that the Borrower provides notice of conversion to the Borrower (the “Notice of Conversion”).
