Forward-Looking Statement

These web pages contain certain "forward-looking statements" within the meaning of the federal securities laws. All statements, other than statements of historical fact included in these web pages are forward-looking statements. These statements are based on management's belief and assumptions using currently available information and expectations as of the date hereof, are not guarantees of future performance and involve certain risks and uncertainties. Although we believe that the expectations reflected in these forward-looking statements are reasonable, we cannot assure you that our expectations will prove to be correct. Therefore, actual outcomes and results could materially differ from what is expressed, implied or forecast in these statements. Any differences could be caused by a number of factors including, but not limited to:

• Risks and uncertainties with respect to the actions of actual or potential competitive suppliers of refined petroleum products in our markets;
• The demand for and supply of crude oil and refined products;
• The spread between market prices for refined products and market prices for crude oil;
• The possibility of constraints on the transportation of refined products;
• The possibility of inefficiencies or shutdowns in refinery operations or pipelines;
• Effects of governmental regulations and policies;
• The availability and cost of our financing;
• The effectiveness of our capital investments and marketing strategies;
• Our efficiency in carrying out construction projects;
• Our ability to acquire refined product operations on acceptable terms and to integrate any future acquired operations;
• The possibility of terrorist attacks and the consequences of any such attacks; general economic conditions; and
• Other financial, operational and legal risks and uncertainties detailed from time to time in our SEC filings.

Cautionary statements identifying important factors that could cause actual results to differ materially from our expectations are set forth from time to time in our Securities and Exchange Commission filings. All forward-looking statements included in these Web pages and all subsequent written or oral forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by these cautionary statements. The forward-looking statements speak only as of the date made and, other than as required by law, we undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.
