            UNAUDITED PRO FORMA CONSOLIDATED STATEMENTS OF OPERATIONS

     Plains All American Pipeline, L.P. ("PAA") is a Delaware limited
partnership formed in September of 1998 to acquire and operate the midstream
crude oil business and assets of Plains Resources Inc. and its wholly owned
subsidiaries. The following unaudited pro forma consolidated statements of
operations are presented to give effect to the transactions described below:

     (1)  The acquisition of certain businesses from Shell Pipeline Company
          including its interests in the Basin Pipeline System, the Rancho
          Pipeline System and the Permian Basin Gathering System (the "Shell
          Acquisition"). 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 acquisition was accounted for using
          the purchase method of accounting.

     (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.

     The unaudited pro forma consolidated statements of operations for the year
ended December 31, 2001, and the for the nine months ended September 30, 2002,
were prepared as if the transactions described above had taken place at the
beginning of the period presented.

     These statements are not necessarily indicative of the results of the
actual operations that would have been achieved had the transactions occurred at
the dates assumed nor are they necessarily indicative of the future results of
operations of the businesses. The unaudited pro forma consolidated statements of
operations should be read in conjunction with the notes thereto and the
historical consolidated financial statements of PAA included in PAA's Annual
Report on Form 10-K for the year ended December 31, 2001, and the unaudited
interim consolidated financial statements for PAA included in PAA's Quarterly
Report on Form 10-Q for the nine months ended September 30, 2002 as well as the
combined financial statements of the businesses acquired in the Shell
acquisition, as of December 31, 2001, and for the year then ended and for the
six months ended June 30, 2002 included in PAA's Form 8-K filed August 9, 2002.

               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

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):
