(2) The issuance and sale in August 2002 of 6,325,000 common units and the application of the proceeds therefrom. (3) The issuance and sale in September 2002 of an aggregate principal amount of $200,000,000 of senior notes and the application of the proceeds therefrom. An unaudited pro forma balance sheet has not been presented since the above transactions are reflected in the historical unaudited consolidated balance sheet as of September 30, 2002 included in PAA's Quarterly Report on Form 10-Q. The accompanying unaudited pro forma consolidated statements of operations for the nine months ended September 30, 2002 and the year ended December 31, 2001 are based upon the following, respectively: (1) The unaudited historical consolidated statement of operations of PAA for the nine months ended September 30, 2002 and the unaudited historical combined statement of operations for the businesses acquired in the Shell Acquisition for the seven months ended July 31, 2002. (2) The historical consolidated statement of operations of PAA for the year ended December 31, 2001 and the historical combined statement of operations for the businesses acquired in the Shell Acquisition for the same period.

PLAINS ALL AMERICAN PIPELINE, L.P. AND SUBSIDIARIES NOTES TO UNAUDITED PRO FORMA CONSOLIDATED STATEMENTS OF OPERATIONS Note 1--Pro Forma Adjustments The pro forma adjustments are as follows: (a) Reflects the elimination of crude oil transportation revenues included in Shell's historical financial statements and the offsetting expense included in our historical financial statements related to an existing contract whereby we transported crude oil on the assets acquired from Shell. On a pro forma basis, these transactions constitute intercompany activities and thus are eliminated in consolidation. (b) Reflects the reduction of operating expenses related to certain field personnel who were not hired as part of the acquisition, as well as the decreases in salaries and benefits associated with the remaining employees. (c) Reflects the adjustment to general and administrative expenses relating to Shell's historical allocation of corporate overhead costs primarily related to payroll costs associated with corporate office management personnel including executives and other corporate office expenses. These costs for our operation of the assets are already included in our historical results. (d) To reverse historical depreciation as recorded by Shell. (e) Reflects depreciation on the acquired assets based on the straight-line method of depreciation over an average useful life of 30 years. The increase over historical depreciation is due to the difference in Shell's historical book value versus the purchase price at fair value. (f) Reflects the adjustment to interest expense for the increase in long- term debt associated with the Shell Acquisition of $304 million from a draw down on the credit facility using the historical interest rates of 5.88% and 3.67% for the periods ended December 31, 2001 and September 30, 2002, respectively. The interest rate used to calculate the adjustment in the September 30, 2002 statement of operations is the historical interest rate for the seven months ended July 31, 2002. Subsequent to that date the transaction is reflected in the historical unaudited consolidated statement of operations of PAA. The impact to interest expense of a 1/8% change in interest rates would be approximately $0.4 million per year. (g) Reflects the adjustment to interest expense resulting from the net decrease in long term debt of approximately $145 million resulting from the repayment of the revolving credit facility with the proceeds of the issuance and sale of 6,325,000 common units using the historical interest rates of 5.88% and 3.69% for the periods ended December 31, 2001, and September 30, 2002, respectively. The interest rate used to calculate the adjustment in the September 30, 2002 statement of operations is the historical interest rate for the eight months ended August 31, 2002. Subsequent to that date the transaction is reflected in the historical unaudited consolidated statement of operations of PAA. (h) Reflects the amortization of debt issue costs of approximately $3 million using the straight line method over the life of the notes, which approximates the effective interest rate method. (i) Reflects the net adjustment to interest expense resulting from the sale of the notes with an effective yield of 7.78% (including the amortization of the debt discount using the effective interest rate method), and the use of those proceeds of approximately $196 million to repay indebtedness outstanding under our revolving credit facility using the historical interest rates of 5.88% and 3.70% for the periods ended December 31, 2001 and September 30, 2002, respectively. PLAINS ALL AMERICAN PIPELINE, L.P. AND SUBSIDIARIES NOTES TO UNAUDITED PRO FORMA CONSOLIDATED STATEMENTS OF OPERATIONS--(Continued) Note 2 - Purchase Price Allocation The Shell Acquisition presented in these pro forma statements has been accounted for using the purchase method of accounting and the purchase price has been allocated in accordance with Statement of Financial Accounting Standards No. 141, Business Combinations. The purchase consists of the acquisition of interests in the Basin Pipeline System, the Rancho Pipeline System and the Permian Basin Gathering System. The purchase price of approximately $322.7 million consisted of (i) $304 million in cash, which was borrowed under the revolving credit facility, (ii) approximately $9.1 million related to the settlement of pre-existing accounts receivable and inventory balances, and (iii) approximately $9.6 million of estimated transaction and closing costs. The acquisition closed and was effective on August 1, 2002. The total purchase price and its allocation are preliminary as the resolution of certain claims and the ultimate amount of transaction costs are based on estimates at this time. We do not expect the resolution of these items to have a material impact on the allocation presented below. The purchase price allocation, based on discounted cash flows which approximate fair value, is as follows (in thousands): Crude oil pipeline assets $248,900 Crude oil pipeline facilities 72,450 Land 1,000 Other property and equipment 350 -------- Total $322,700 ========
