This release contains forward-looking statements with respect to the sale of Marathon Oil's interest in Angola Block 31, expectations with respect to the use of proceeds from the sale, and projected asset dispositions through 2013. Some factors that could potentially affect the sale of the Company's interest in Angola Block 31 are completion of the necessary government, regulatory and third-party approvals, and satisfaction of other customary closing conditions. The expectations with respect to the use of proceeds could be affected by changes in the prices and demand for crude oil and natural gas, actions of competitors, disruptions or interruptions of the Company's exploration or production operations, unforeseen hazards such as weather conditions or acts of war or terrorist acts, and other operating and economic considerations.

Actual results may differ materially from these expectations, estimates and projections and are subject to certain risks, uncertainties and other factors, some of which are beyond the Company's control and difficult to predict.
