AND SUBSIDIARIES NOTES TO UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS Note 1--Pro Forma Adjustments The pro forma adjustments are as follows: a. Reflects the net proceeds of borrowings under the bank credit facility to fund the Shell Acquisition at closing. b. Records the assets purchased in the Shell Acquisition based on the purchase method of accounting. The purchase price was $322.7 million and consisted of (i) approximately $304 million in cash of which $15.7 million was paid as a deposit in May 2002, (ii) an estimated $9.1 million related to the settlement of pre-existing inventory balances and (iii) the accrual of approximately $9.6 million of other transaction and closing costs (See Note 2). c. Reflects the adjustment to interest expense for the increase in long term debt of $304 million from a draw down on the credit facility using historical interest rates of 5.88% and 3.68% for the periods ended December 31, 2001 and June 30, 2002, respectively. The impact to interest expense of a 1/8% change in interest rates would be approximately $0.4 million per year. d. Reflects the elimination of crude oil transportation revenues included in Shell's historical financial statements and the offsetting expense included in PAA's historical financial statements related to an existing contract whereby PAA 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. e. 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 PAA's operation of the assets are already included in our historical results. f. Reflects the reduction of operating expenses related to certain field personnel which were not hired as part of the acquisition as well as the decreases in salaries and benefits associated with the remaining employees. g. To reverse historical depreciation as recorded by Shell. h. 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. 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 certain businesses from Shell Pipeline Company, including its interests in the Basin 5 PLAINS ALL AMERICAN PIPELINE, L.P. AND SUBSIDIARIES NOTES TO UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Pipeline System, the Rancho Pipeline System and the Permian Basin Gathering System. The purchase price of approximately $322.7 million is net of interest earned on the deposit and the settlement of pre-existing accounts receivable and inventory balances and purchase price adjustments as provided for in the amended purchase and sale agreement, and includes other transaction and closing costs. The acquisition closed on August 1, 2002 which was also the effective date. 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 ======== 6
