Forward-Looking Statement Statements made in this presentation that are not historical facts are forward- looking statements. We believe the assumptions underlying these statements are reasonable, but caution you that such forward-looking statements involve risks that may affect our prospects and performance, causing actual results to differ from those discussed here. Such risks and uncertainties include, among other things: our ability to successfully consummate announced acquisitions and integrate them into existing operations; the ability of such acquisitions to be cash-flow accretive; increased competition; changes in demand for crude oil we buy and sell, as well as for crude oil and refined products that connect, store and distribute; the loss of a major customer; changes in our tariff rates; changes in throughput of third-party pipelines to our pipelines and terminals; changes in operating conditions and costs; changes in level of environmental remediation spending; potential equipment malfunction; potential labor relations problems; the legislative or regulatory environment; plant construction/repair delays; and political and economic conditions, including the impact of potential terrorists acts and international hostilities. These and other applicable risks and uncertainties are described more fully in our Quarterly Form 10-Q (filed with the Securities and Exchange Commission on May 9, 2005). We undertake no obligation to update publicly any forward-looking statements in this presentation, whether as a result of new information or future events.

EBITDA Reconciliation ($ million) Year ended December 31, Quarter ended March 31, 2004 2003 2005 2004 EBITDA (1) East 45.3 47.7 11.3 10.7 Terminals 47.9 41.4 13.6 10.6 West 16.1 17.5 3.7 4.0 109.3 106.6 28.6 25.3 Depreciation and amortization (31.9) (27.2) (8.1) (7.5) Operating Income 77.4 79.5 20.5 17.8 Management of the Partnership believes EBITDA and distributable cash flow information enhances an investor's understanding of a business ability to generate cash for payment of distributions and other purposes. In addition, EBITDA is also used as a measure in the Partnership's $250 million revolving credit facility in determining its compliance with certain covenants. However, there may be contractual, legal, economic or other reasons which may prevent the Partnership from satisfying principal and interest obligations with respect to indebtedness and may require the Partnership to allocate funds for other purposes. EBITDA and distributable cash flow do not represent and should not be considered alternatives to net income, operating income or cash flows from operating activities as determined under United States generally accepted accounting principles and may not be comparable to other similarly titled measures of other businesses. 56 (1) Earnings before interest, taxes, depreciation and amortization
