Note 1 - Organization

     Plains AAP, L.P. (the "Partnership") is a Delaware limited partnership,
which was formed on May 21, 2001 and, through a series of transactions, was
capitalized on June 8, 2001. Through these series of transactions Plains
Holdings Inc. (formerly known as Plains All American Inc. conveyed to the
Partnership its general partner interest in Plains All American Pipeline, L.P.
("PAA") and, subsequently, sold a portion of its interest in the newly formed
partnership to certain investors. The ownership interest in the Partnership
(collectively, the "Partners") at December 31, 2001, was comprised of a 1%
general partner interest held by Plains All American GP LLC (the "General
Partner") and the following limited partner interests:

     .    Plains Holdings Inc. - 43.560%

     .    Sable Investments, L.P. -18.810%

     .    KAFU Holdings, L.P. - 16.253%

     .    E-Holdings III, L.P. - 8.910%

     .    Mark E. Strome - 2.113%

     .    PAA Management L.P. - 3.960%

     .    Strome Hedgecap Fund, L.P. - 1.055%

     .    John T. Raymond - .990%

     .    First Union Investors - 3.349%

     As of December 31, 2001, the Partnership owns a 2% general partner interest
in PAA and an approximate 1% limited partner interest, consisting of 450,000
subordinated units (see Note 4) in PAA. PAA was formed in the fourth quarter of
1998, as a result of Plains Resources Inc. conveying all of its interest in
their midstream crude oil business, the All American Pipeline and the San
Joaquin Valley Gathering System to PAA in exchange for an indirect interest in
(1) 6,974,239 Common Units, 10,029,619 Subordinated Units and an effective 2%
general partnership interest in PAA and its subsidiary operating partnerships;
(2) the right to receive incentive distributions; and (3) the assumption by PAA
of $175.0 million of indebtedness incurred by Plains All American Inc. in
connection with the All American Pipeline acquisition.

PAA's operations are concentrated in Texas, Oklahoma, California and Louisiana
and in the Canadian provinces of Alberta, Saskatchewan and Manitoba, and can be
categorized into two primary business activities:

     .    Crude Oil Pipeline Transportation. PAA owns and operates over 3,000
          miles of gathering and mainline crude oil pipelines located throughout
          the United States and Canada. Its activities from pipeline operations
          generally consist of transporting third-party volumes of crude oil for
          a fee.

     .    Terminalling and Storage Activities and Gathering and Marketing
          Activities. In connection with its terminalling and storage
          activities, PAA owns and operates approximately 11.5 million barrels
          of above-ground crude oil terminalling and storage facilities,
          including the terminalling and storage facility at Cushing, Oklahoma.
          Cushing is the largest crude oil trading hub in the United States and
          the designated delivery point for New York Mercantile Exchange
          ("NYMEX") crude oil futures contracts. PAA's terminalling and storage
          operations generate revenue through a combination of storage and
          throughput charges to third parties. PAA also utilizes its storage
          tanks to counter-cyclically balance its gathering and marketing
          operations and to execute different hedging strategies to lock in
          profits and reduce the negative impact of crude oil market volatility.
          Its gathering and marketing operations include: the purchase of crude
          oil at the wellhead, and the bulk purchase

                                       7

          of crude oil at pipeline and terminal facilities; the transportation
          of crude oil on trucks, barges or pipelines; the subsequent resale or
          exchange of crude oil at various points along the crude oil
          distribution chain; and, the purchase of LPG from producers, refiners
          and other marketers, and sale of LPG to end users and retailers.

Note 2 - Summary of Significant Accounting Policies

Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the balance
sheet. Although management believes these estimates are reasonable, actual
results could differ from these estimates.

Investment in PAA

     The Partnership accounts for its ownership investment in PAA in accordance
with Accounting Principles Board Opinion No. 18, "The Equity Method of
Accounting for Investments in Common Stock". Although the Partnership owns less
than 50% of PAA, the Partnership has the ability to exercise significant
influence; and therefore, accounts for the investment under the equity method.

Income Taxes

     No liability for U.S. Federal or Canadian income taxes related to our
operations is included in the accompanying financial statement because, as a
partnership, we are not subject to Federal, State or Provincial income tax; and
the tax effect of our activities accrues to the Partners. The Partners may be
required to file U.S. Federal and State, as well as Canadian Federal and
Provincial income tax returns.

Note 3 -Investment in PAA

     The Partnership's investment in PAA at December 31, 2001, is $51.8 million.
The summarized financial information of PAA at December 31, 2001, is presented
below (in thousands):

Current assets                              $558,082
Non - current assets                        $703,169
Current liabilities                         $505,160
Long-term debt and other long-term
 liabilities                                $353,294
Partners' capital                           $402,797

     At the date of inception, the Partnership's investment in PAA exceeded its
share of the underlying equity in the net assets of PAA by $44.5 million. This
excess is related to the fair value of PAA's crude oil pipelines and is
amortized on a straight-line basis over their estimated useful life of 30 years.

Note 4 - Contribution of Subordinated Units

     On June 8, 2001, certain of our limited partners contributed to the
Partnership an aggregate of 450,000 subordinated units of PAA. These
subordinated units are intended for use in connection with an option plan (see
Note 6) pursuant to which certain members of the management of our general
partner will, subject to the satisfaction of vesting criteria, have a right to
purchase a portion of such subordinated units. Until the exercise of such
options, we will continue to own and receive any distributions paid by PAA with
respect to such subordinated units. Any distributions we make as a result of the
receipt of distributions on the subordinated units will be paid to our limited
partners in proportion to the original contribution of such subordinated units.

                                       8

Note 5 - Partner's Capital

     The Partnership distributes all of its available cash, less reserves
established by management, on a quarterly basis. Except as described in Note 4,
distributions are paid to the partners in proportion to their percentage
interest in the Partnership.

     The General Partner manages the business and affairs of the Partnership.
Except for situations in which the approval of the limited partner is expressly
required by the Partnership agreement, or by nonwaivable provisions of
applicable law, the General Partner has full and complete authority, power and
discretion to manage and control the business, affairs and property of the
Partnership, to make all decisions regarding those matters and to perform any
and all other acts or activities customary or incident to the management of the
Partnership's business, including the execution of contracts and management of
litigation. The General Partner employs all officers and personnel involved in
the operation and management of PAA and its subsidiaries. PAA reimburses the
General Partner for all expenses, including compensation expenses, related to
such operation and management. The Partnership has no commitment or intent to
fund cash flow deficits or furnish other financial assistance to PAA.

Note 6 - Performance Option Plan

     In June 2001, the Performance Option Plan (the "Plan") was approved by the
General Partner to grant options to purchase up to 450,000 subordinated units
(See Note 4) to employees of the General Partner. As of December 31, 2001,
options to purchase 312,500 units have been granted under the Plan. The options
have been granted with an exercise price of $22, less 80% of any distributions
on these subordinated units from the date of grant until the date of exercise.
At December 31, 2001 the exercise price has been reduced to $21.19 for
distributions made since the date of grant. The options have a ten-year term and
vest only upon PAA meeting certain levels of distributions. These options are
considered performance awards and will be accounted for at fair value upon
vesting. No compensation has been recorded by the Partnership as no vesting has
occurred as of December 31, 2001. Pursuant to the first quarter 2002
distribution, paid on May 15, 2002, PAA attained the distribution level
necessary for 25% of the units to vest.

Note 7 - Accounting Pronouncements

     In June 2001, the Financial Accounting Standards Board ("FASB") issued
Statements of Financial Accounting Standards No. 142 "Goodwill and Other
Intangible Assets" ("SFAS 142"). SFAS 142 changes the accounting for goodwill
and other intangible assets after an acquisition. The most significant changes
made by SFAS 142 are:1) goodwill and intangible assets with indefinite lives
will no longer be amortized; 2) goodwill and intangible assets with indefinite
lives must be tested for impairment at least annually; and 3) the amortization
period for intangible assets with finite lives will no longer be limited to
forty years. We adopted this Standard effective January 1, 2002, and there was
no effect on either our financial position, results of operations or cash flows.

     In June 2001, the FASB also issued SFAS 143 "Asset Retirement Obligations".
SFAS 143 establishes accounting requirements for retirement obligations
associated with tangible long-lived assets, including (1) the timing of the
liability recognition, (2) initial measurement of the liability, (3) allocation
of asset retirement cost to expense, (4) subsequent measurement of the liability
and (5) financial statement disclosures. SFAS 143 requires that an asset
retirement cost should be capitalized as part of the cost of the related
long-lived asset and subsequently allocated to expense using a systematic and
rational method. We will adopt the statement effective January 1, 2003, as
required. The transition adjustment resulting from the adoption of SFAS 143 will
be reported as a cumulative effect of a change in accounting principle. SFAS 143
will only impact the Partnership to the extent PAA is affected. At this time, we
cannot reasonably estimate the effect of the adoption of this statement on
either our financial position, results of operations, or cash flows.
