        Further to your request to extend the Availability Period in accordance
        with Clause 7.3 (Extension) of the Facility Agreement and to make
        certain other amendments to the Facility Agreement, we confirm our

        364 days from the date of this Agreement" in the second line of

        follows:

        course of business given extensions or waivers of the statute of
        limitations relating to various state, local and foreign taxes or
        impositions, none of which might reasonably be expected to result in a

               financial condition as at such dates and the results of its
               operations for the fiscal year and three-month period ended on
               such dates (subject, in the case of the financial statements as
               at 30 September 2001 to normal year-end audit adjustments) unless
               expressly disclosed to the contrary in those financial statements
               or in writing by the Guarantor to the Lender on or before the
               date of this amendment."

               the period ending 30 September 2001 filed by the Guarantor with
               the U.S. Securities and Exchange Commission are the most current
               10-K and 10-Q financial statements of the Guarantor and fairly
               represent in all material respects the Guarantor's financial
               position as at those dates."

1.5     CLAUSE 19.13 (NO PROCEEDINGS PENDING OR THREATENED)
