(4) The issuance of the notes in aggregate principal amount of $350.0 million.

The unaudited pro forma consolidated balance sheet as of March 31, 2001 and the unaudited pro forma statements of income for the three months ended March 31, 2001 and the year ended December 31, 2000 are based upon the following, respectively: (1) The historical balance sheet of Plains All American Pipeline at March 31, 2001.

AND SUBSIDIARIES NOTES TO UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS Pro Forma Adjustments 1. Reflects the net proceeds of borrowings under the bank credit facility to fund the Murphy acquisition. 2. Records the assets purchased from Murphy based on the purchase method of accounting. 3. Reflects the estimated net proceeds to Plains All American Pipeline of $100.7 million from the second quarter of 2001 issuance of 3,966,700 common units at an offering price of $26.05 per common unit, net of underwriters' discounts and commissions and offering expenses of approximately $4.7 million and the general partner's capital contribution of approximately $2.1 million to maintain its aggregate 2% general partner interest. 4. Reflects the repayment of approximately $100.7 million of debt outstanding under our bank credit facility with the total net proceeds from our second quarter of 2001 equity offering. 5. Reflects adjustments to interest expense to account for (i) the repayment of approximately $100.7 million of debt outstanding under our bank credit facility with the total net proceeds from our second quarter of 2001 equity offering, (ii) the repayment of outstanding borrowings under our bank credit facility with net proceeds raised in the notes offering and (iii) the increase in total long term debt of $350.0 million from proceeds raised in the notes offering. 6. Reflects the estimated net proceeds to Plains All American Pipeline of $345.2 million from the issuance of $350.0 million aggregate principal amount of notes, net of initial purchasers' discounts and estimated issuance expenses of approximately $4.8 million. 7. Reflects the repayment of outstanding borrowings under the bank credit facility at March 31, 2001 from net proceeds raised in the notes offering. 8. Reflects the adjustment of the historical market valuation charge/credit reflected in Murphy's historical financial statements to reflect such amounts based on the average cost inventory method utilized by Plains All American Pipeline. Murphy utilized the last-in, first-out method to determine inventory cost. 9. Reflects the elimination of expenses associated with Murphy's pension plan in which Murphy's employees are no longer entitled to participate so that general and administrative expenses reflect the ongoing cost of employee benefits to Plains All American Pipeline. 10. Reflects Canadian withholding tax (at the rate of 10%) on interest expense paid on an intercompany loan used to complete the Murphy acquisition. 11. Reflects pro forma depreciation and amortization expense based on the purchase price of the Murphy acquisition. The pro forma composite useful depreciable life of the Murphy assets acquired is 20 years. Debt issue costs incurred in connection with the acquisition, which totaled $1.3 million, are amortized using the straight-line method over the term of the related debt. These costs are not materially different from the amortization of debt issue costs computed under the interest method. 12. Reflects the elimination of historical Murphy depreciation and amortization expense. 5 PLAINS ALL AMERICAN PIPELINE, L.P. AND SUBSIDIARIES NOTES TO UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS 13. Reflects pro forma interest expense on (i) borrowings of approximately $100 million under the Term Loan and (ii) borrowings of $61 million under the U.S. Revolver. Pro forma interest expense was calculated based on a composite annual interest rate of 7.5%. The effect of a 1/8% change in the pro forma interest rate would be approximately $200,000 for the year ended December 31, 2000 and $50,000 for the three month period ended March 31, 2001. 14. Reflects the elimination of the historical income tax provision as income taxes will be borne by the partners and not Plains All American Pipeline. 15. Reflects revenues and costs of sales related to the Manito pipeline system for January through June 2000 due to the fact that Murphy purchased the remaining 47.5% interest in the system effective July, 2000. Pro Forma As Adjusted Earnings Per Limited Partner Unit Pro forma as adjusted earnings per limited partner unit is determined by dividing the pro forma income from continuing operations that would have been allocated to the common and subordinated unitholders, which is 98% of pro forma income from continuing operations, by the number of common and subordinated units expected to be outstanding at the closing of the offering. For purposes of this calculation the minimum quarterly distribution was assumed to have been paid to both common and subordinated unitholders and the number of common and subordinated units outstanding was assumed to have been outstanding the entire period. Pursuant to the partnership agreement, to the extent that the minimum quarterly distribution is exceeded, the general partner is entitled to certain incentive distributions which will result in less income proportionately being allocated to the common and subordinated unitholders. Basic and diluted pro forma earnings per limited partner common and subordinated unit are equal as there are no dilutive units. 6
