To assist in the transition, Mr Drosdick will remain as non-executive chairman of the board until December 31, 2008.

An experienced oil industry executive, Ms Elsenhans joins Sunoco most recently from Shell Downstream, a subsidiary of the Royal Dutch Shell Group, where she served since 2005, as executive vice president of global manufacturing.

Ms Elsenhans was responsible for Shell’s refining and chemical manufacturing operations, which included 40 plants and more than 17,000 employees. From 2003 to 2005, she served concurrently as president of the Shell Oil Company, and president and CEO of Shell Oil Products USA.

Mr Drosdick said: Lynn’s record at Shell speaks for itself, she knows the industry intimately and has proven to be a capable manager of a large and complex business. With her qualifications, track record of performance and fresh perspective, Lynn is clearly ready to build on Sunoco’s success.
