FACTORS AFFECTING THIRD QUARTER RESULTS

o    On July 19, 2002 Suncor successfully completed a maintenance shutdown of
     one of its two Oil Sands upgraders to repair a fractionator. The outage
     lasted eight days, during which oil production averaged about 95,000
     barrels per day.

o    During the third quarter, the Canadian dollar weakened relative to the U.S.
     dollar resulting in a reduction of net earnings due to an expected $25
     million foreign exchange loss on Suncor's $500 U.S. dollar denominated
     debt. This loss has no impact on cash flow from operations.

OTHER NOTES ON THIRD QUARTER RESULTS

o    Suncor has hedged 50 per cent of budgeted production in 2002 and 35 per
     cent in 2003. The company continues to work towards hedging 30 per cent of
     budgeted production in 2004, 2005 and 2006. The objective of Suncor's
     hedging program is to lock in prices on a portion of the company's future
     production to reduce exposure to market volatility, manage debt levels and
     support the company's ability to finance future growth.

o    The following table sets out the company's approximate crude oil hedge
     position as of September 30, 2002 for the years indicated.
