We have not audited any financial statements of the Company as at any date or for any period subsequent to December 31, 2004.  Although we have performed an audit for the year ended December 31, 2004, the purpose and therefore the scope of the audit was to enable us to express our opinion on the consolidated financial statements as at December 31, 2004 and for the year then ended, but not on the consolidated financial statements for any interim period within that year.  Therefore, we are unable to and do not express an opinion on the Second Quarter Financial Statements, or on the financial position, results of operations or cash flows of the Company as at any date or for any period subsequent to December 31, 2004.

We have, however, performed a review of the Second Quarter Financial Statements of the Company. We performed our review in accordance with Canadian generally accepted standards for a review of interim financial statements by an entity’s auditor. Such an interim review consists principally of applying analytical procedures to financial data, and making enquiries of, and having discussions with, persons responsible for financial and accounting matters. An interim review is substantially less in scope than an audit, whose objective is the expression of an opinion regarding the financial statements. An interim review does not provide assurance that we would become aware of any or all significant matters that might be identified in an audit.

Based on our review, we are not aware of any material modification that needs to be made for the Second Quarter Financial Statements to be in accordance with Canadian generally accepted accounting principles.
