Suncor Energy announces senior management appointments

Calgary, Alberta (March 4, 2008) — Suncor Energy Inc. Chief Operating Officer Steve Williams today announced three appointments to the company's executive leadership team.

Jay Thornton assumes the role of executive vice president, Refining and Marketing, with responsibility for Suncor's downstream business in Canada and the United States, including refining operations, and industrial and retail marketing of refined products, as well as the company's growing renewable energy business. Thornton was previously senior vice president, Business Integration and has held a variety of roles in corporate planning and strategy in Suncor's oil sands and refining and marketing businesses. An industry veteran with more than 20 years experience, Thornton previously held various commercial, operations and planning executive positions with a major multinational oil and gas company, primarily in the downstream sector. He replaces outgoing Executive Vice President Tom Ryley, who is leaving in March.

Taking over from Thornton as senior vice president, Business Integration is Bart Demosky. In his new role, Demosky assumes responsibility for enterprise-wide business services and integration of technology and processes, including supply chain management. Demosky most recently served as treasurer and was a key leader of Suncor's finance team, providing guidance on the company's financial risk management initiatives and ensuring Suncor has the financial resources necessary to support the company's growth strategy. Prior to joining Suncor, Demosky held various senior roles in finance, risk management and energy marketing in the energy and utilities sectors.

Joel Croteau has been appointed senior vice president, Natural Gas and In Situ Resources. In this role he will be responsible for continuing to develop Suncor's natural gas production as a financial hedge against the company's internal energy demands. He is also responsible for oil sands in situ subsurface technology and reservoir development. Croteau is a 29-year Suncor veteran who has held a variety of positions in exploration and production, business services, finance, and corporate planning and strategy development. He replaces Dave Byler, who is retiring from Suncor in April.

"The quality of the senior management appointments announced today demonstrates the bench strength of Suncor's leadership team," said Williams. "I expect a smooth transition as we continue to grow our business and work to deliver safe, reliable and environmentally responsible energy production."
