Forward-Looking Statements This presentation contains forward-looking statements within the meaning of federal securities laws regarding both MPC and MPLX.

Such forward-looking statements are not guarantees of future performance and are subject to risks, uncertainties and other factors, some of which are beyond the companies’ control and are difficult to predict. Factors that could cause MPC’s actual results to differ materially from those in the forward-looking statements include: volatility in and/or degradation of market and industry conditions; the availability and pricing of crude oil and other feedstocks; slower growth in domestic and Canadian crude supply; completion of pipeline capacity to areas outside the U.S. Midwest; consumer demand for refined products; transportation logistics; the reliability of processing units and other equipment; the ability to successfully implement growth opportunities; impacts from repurchases of shares of MPC common stock under share repurchase authorizations, including the timing and amounts of any common stock repurchases; state and federal environmental, economic, health and safety, energy and other policies and regulations, including the cost of compliance with the Renewable Fuel Standard; other risk factors inherent to MPC’s industry; and the factors set forth under the heading “Risk Factors” in MPC’s Annual Report on Form 10-K for the year ended December 31, 2012, filed with the Securities and Exchange Commission (SEC). Factors that could cause MPLX actual results to differ materially from those in the forward-looking statements include: the adequacy of MPLX capital resources and liquidity, including, but not limited to, availability of sufficient cash flow to pay distributions and execute business plans; the timing and extent of changes in commodity prices and demand for crude oil, refined products, feedstocks or other hydrocarbon-based products; volatility in and/or degradation of market and industry conditions; completion of pipeline capacity by competitors; disruptions due to equipment interruption or failure, including electrical shortages and power grid failures; the suspension, reduction or termination of MPC’s obligations under commercial agreements; the ability to successfully implement growth strategies, whether through organic growth or acquisitions; state and federal environmental, economic, health and safety, energy and other policies and regulations; other risk factors inherent to MPLX’s industry; and the factors set forth under the heading “Risk Factors” in MPLX’s Annual Report on Form 10-K for the year ended December 31, 2012, filed with the SEC. In addition, the forward-looking statements included herein could be affected by general domestic and international economic and political conditions. Unpredictable or unknown factors not discussed here, in MPC’s Form 10-K or in MPLX’s Form 10-K could also have material adverse effects on results.
