UPSTREAM

Exploration and Production
Marathon's exploration activities are focused on adding profitable production to existing core areas (the U.S., Equatorial Guinea, Libya and the North Sea) and developing potential new core areas (Angola, Indonesia and Poland). Marathon's production operations supply liquid hydrocarbons and natural gas to the growing world energy markets. Worldwide production operations are currently focused in North America, Africa and Europe. The Company also holds ownership interests in both operated and outside-operated oil sands leases in Canada that could be developed using in-situ methods of extraction.

Oil Sands Mining
Marathon owns a 20 percent outside-operated interest in the Athabasca Oil Sands Project (AOSP), which includes the existing Muskeg River Mine and the Scotford Upgrader, the upcoming Jack Pine Mine and Scotford Upgrader expansion and additional prospective acreage in Alberta, Canada. These assets give Marathon access to stable, long-life Organization for Economic Cooperation and Development (OECD) production through several future phased expansions.

Integrated Gas
Marathon's integrated gas business adds value through the development of opportunities created by demand for natural gas. This business complements the Company's exploration and production operations and opens a wide array of investment opportunities designed to add sustainable value growth.

DOWNSTREAM

Refining, Marketing and Transportation
Marathon has extensive refining, marketing and transportation operations concentrated primarily in the Midwest, Upper Great Plains, Gulf Coast and Southeast regions of the U.S. Marathon ranks as the fifth largest crude oil refiner in the U.S. and the largest in the Midwest.
