                      PLAINS ALL AMERICAN PIPELINE, L.P.
             UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS

    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 financial
statements are presented to give effect to the transaction described below:

        The acquisition of certain businesses from Shell Pipeline Company
    ("Shell"), 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 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 acquisition will be accounted for
    using the purchase method of accounting.

    The unaudited pro forma consolidated balance sheet as of June 30, 2002 and
the unaudited pro forma statements of operations for the six months ended June
30, 2002 and the year ended December 31, 2001 are based upon the following,
respectively:

    (1) The historical balance sheet of Plains All American Pipeline, L.P. at
        June 30, 2002.

    (2) The historical consolidated statement of operations of Plains All
        American Pipeline, L.P. for the six months ended June 30, 2002 and the
        historical combined statement of operations for the businesses acquired
        in the Shell Acquisition for the same period.

    (3) The historical consolidated statement of operations of Plains All
        American Pipeline, L.P. 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 financial statements are not
necessarily indicative of the results of the actual or future operations or
financial condition that would have been achieved had the transactions occurred
at the dates assumed (as noted below). The unaudited pro forma consolidated
financial statements should be read in conjunction with the notes thereto and
the historical audited financial statements of Plains All American Pipeline,
L.P. for the year ended December 31, 2001 and the unaudited interim financial
statements for Plains All American Pipeline, L.P. for the six months ended June
30, 2002 as well as those for the businesses acquired in the Shell Acquisition,
for the same periods.

    The following unaudited pro forma consolidated statements of operations for
the six months ended June 30, 2002 and the year ended December 31, 2001 have
been prepared as if the transaction described above had taken place on January
1, 2001. The unaudited pro forma consolidated balance sheet at June 30, 2002
assumes the transaction was consummated on that date.

              PLAINS ALL AMERICAN PIPELINE, L.P. 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
