PRO FORMA FINANCIAL DATA The following unaudited pro forma financial data reflects our historical results as adjusted on a pro forma basis to give effect to our April 2004 offering of common units, together with the completion of the acquisition of Spectrum Field Services, Inc. and the offering of 2,100,000 common units, assuming that the underwriters do not exercise their over-allotment option to purchase up to an additional 315,000 common units, as referred to in Item 5 of this Form 8-K report. The unaudited pro forma balance sheet is prepared as though these transactions occurred as of March 31, 2004. The unaudited pro forma statement of operations for the year ended December 31, 2003 is prepared as though these transactions occurred as of January 1, 2003. The unaudited pro forma statement of operations for the three months ended March 31, 2004 is prepared as though these transactions occurred as of January 1, 2004. The acquisition and offering adjustments are described in the notes to the unaudited pro forma financial data. The unaudited pro forma financial data and accompanying notes should be read together with our "Management's Discussion and Analysis of Financial Condition and Results of Operations" and our and Spectrum's historical financial statements and related notes included or incorporated by reference in the prospectus supplement referred to in Item 5 of this Form 8-K report. Because we will not complete the Alaska Pipeline acquisition due to recent events, that acquisition is not included in these unaudited pro forma financial statements. We accounted for the acquisition of Spectrum in the unaudited pro forma financial statements using the purchase method in accordance with the guidance of Statement of Financial Accounting Standards No. 141, "Business Combinations." For purposes of developing the unaudited pro forma financial information, we have allocated the purchase price to Spectrum's gas gathering and transmission facilities based on fair market value. The unaudited pro forma financial statements presented are for informational purposes only and are based upon available information and assumptions that we believe are reasonable under the circumstances. You should not construe the unaudited pro forma financial statements as indicative of the combined financial position or results of operations that we and Spectrum would have achieved had the transaction been consummated on the dates assumed. Moreover, they do not purport to represent our and Spectrum's combined financial position or results of operations for any future date or period or constitute a representation that we will complete the Spectrum acquisition.
