      Lender not less than ten (10) Business Days' prior written notice of its
      intention to prepay the Facility.

	5. 	
      Bonus. As additional consideration for the Advance
      of the Facility, the Borrower shall pay to the Lender the following

      Advance (the "First Tranche Bonus Shares"),
and

-4-

	 	(b) 	
      such number of common shares in the capital of the
      Borrower issued from treasury equal to five percent (5%) of the

      closing price of the Borrower's common shares through the facilities of
      the Exchange immediately preceding September 30, 2006, less a 10% discount
      (the "Second Tranche Bonus Shares").

		
      The Bonus Shares will be subject to a hold period in
      Canada of four months from their date of issue in accordance with
      applicable securities laws and the policies of the Exchange, and will bear
      a legend to that effect.

	 	 	 
	6. 	
      Interest. From and after January 1, 2007, interest
      will accrue on the Outstanding Balance at the rate of twenty percent (20%)
      per annum, calculated daily and compounded monthly (effective annual rate
      of 21.94%), and be payable by the Borrower to the Lender monthly in
      arrears, on the last Business Day of every month, as well as after
      maturity, default and judgment.

      successors and permitted assigns.

      Criminal Code Compliance. In this paragraph the
      terms "interest", "criminal rate" and "credit advanced" have the meanings
      ascribed to them in Section 347 of the Criminal Code (Canada) as amended
      from time to time. The Borrower and the Lender agree that, notwithstanding
      any agreement to the contrary, no interest on the Facility or the credit
      advanced by the Lender under this Agreement will be payable in excess of
      that permitted under the laws of Canada. If the effective rate of
      interest, calculated in accordance with generally accepted actuarial
      practices and principles, would exceed the criminal rate on the credit
      advanced, then:

	 	 	 
		(a) 	
      the elements of return which fall within the term
      "interest" will be reduced to the extent necessary to eliminate such
      excess;

	 	 	 
		(b) 	
      any remaining excess that has been paid will be credited
      towards prepayment of the Facility; and

	 	 	 
		(c) 	
      any overpayment that may remain after such crediting will
      be returned forthwith to the Borrower upon demand, and, in the event of
      dispute, a Fellow of the Canadian Institute of Actuaries appointed by the
      Lender will perform the relevant calculations and determine the
      reductions, modifications and credits necessary to effect the foregoing
      and the same will be conclusive and binding on the parties. This
      Agreement, the Note and all related agreements and documents will
      automatically be modified to reflect such modifications without the
      necessity of any further act or deed of the Borrower and the Lender to
      give effect to them.

	25. 	
      Invalidity. If at any time any one or more of the
      provisions hereof is or becomes invalid, illegal or unenforceable in any
      respect under any law, the validity, legality and enforceability of the
      remaining provisions hereof will not in any way be affected or impaired
      thereby to the fullest extent possible by law.

	26. 	
      Governing Laws. This Agreement will be governed by
      and interpreted in accordance with the laws of the Province of British
      Columbia and the laws of Canada applicable therein. The Borrower submits
      to the non-exclusive jurisdiction of the Courts of the Province of British
      Columbia and agrees to be bound by any suit, action or proceeding
      commenced in such Courts and by any order or judgment resulting from such
      suit, action or proceeding, but the foregoing will in no way limit the
      right of the Lender to commence suits, actions or proceedings based on
      this Agreement in any jurisdiction it may deem
  appropriate.

	27. 	
      Amendment. This Agreement supersedes the Term
      Sheet and all prior agreements and discussions between the parties with
      respect to the subject matter set forth herein.
This

-15-

		
      Agreement may be varied or amended only by or pursuant to
      an agreement in writing signed by the parties hereto.

	 	 
	28. 	
      Schedules. All Schedules attached hereto will be
      deemed fully a part of this Agreement.

	 	 
	29. 	
      Further Assurances. The Borrower will, and will
      cause its Subsidiaries, from time to time and upon reasonable request of
      the Lender do, execute and deliver all further assurances, acts and
      documents for the purpose of giving full force and effect to the
      covenants, agreements and provisions herein contained, including but not
      limited to all such further assurances, acts and documents as may be
      required to obtain exchange control approval of the South African Reserve
      Bank, as contemplated above.

	 	 
	30. 	
      Currency. All references herein to "dollars" or
      "$" are to Canadian dollars, unless otherwise indicated.

	 	 
	31. 	
      Counterparts. This Agreement may be signed in one
      or more counterparts, originally or by facsimile, each such counterpart
      taken together will form one and the same
agreement.
