MANAGEMENTS
DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS-CANADIAN
SUPPLEMENT (in United States dollars, unless otherwise indicated, and in accordance with CDN GAAP)

Acquired in-process
technology

Canadian GAAP requires capitalization
of the value assigned to acquired in-process technology and amortization of this value
over its estimated useful life. Under U.S. GAAP, this value is written off immediately.
The impact of this difference was to decrease income before taxes by $0.5 million and $1.6
million for the three months ended August 31, 2003 and August 31, 2002,
respectively, compared to U.S. GAAP. For the six-month periods ending August 31, 2003 and
August 31, 2002 the impact of this difference was to decrease income before taxes by $1.0
million and $3.4 million, respectively, as compared to U.S. GAAP.

Investment tax credits

Canadian GAAP requires that
investment tax credits be deducted from operating expense. Under U.S. GAAP, these amounts
are deducted from the income tax provision. The impact of this difference was to increase
income before taxes and the income tax provision by $4.9 million and $1.3 million for the
three months ended August 31, 2003 and August 31, 2002, respectively compared to U.S.
GAAP. For the six-month periods ended August 31, 2003 and August 31, 2002 the impact of
this difference was to increase income before taxes and the income tax provision by $7.3
million and $2.7 million, respectively as compared to U.S. GAAP.

Deferred income taxes
related to acquired in-process technology

The above noted difference related to
the capitalization of in-process technology created an additional deferred income tax
liability on the Canadian GAAP balance sheet as the capitalization of the in-process
technology created a temporary difference. The amortization of this balance decreased the
Canadian GAAP income tax provision by $0.2 million and $0.6 million for the quarters ended
August 31, 2003 and August 31, 2002, respectively as compared to U.S. GAAP. For
the six-month periods ended August 31, 2003 and August 31, 2002 the amortization of this
balance decrease the Canadian GAAP income tax provision by $0.3 million and $1.3 million,
respectively as compared to U.S. GAAP.
