Our report dated February 1, 2002, except as to note 2, which is as of March 14,
2002, as to note 5, which is as of February 20, 2002, and as to note 9(h), which
is as of May 1, 2002, contains Comments by the Auditors for U.S. Readers on
Canada - U.S. Reporting Differences which states that in the United States,
reporting standards for auditors require the addition of an explanatory
paragraph (following the opinion paragraph) when the financial statements are
affected by conditions and events that cast substantial doubt on the Company's
ability to continue as a going concern such as those described in note 2 to the
consolidated financial statements. Our report to the shareholders is expressed
in accordance with Canadian reporting standards, which do not permit a reference
to such conditions and events in the auditors' report when these are adequately
disclosed in the financial statements.
