Item 7.   Financial Statements and Exhibits

           (c) Exhibit 99.1 - Press Release dated April 25, 2003

Item 9 and 12.  Regulation FD Disclosure; Results of Operations and Financial

     Plains All American Pipeline, L.P. (the "Partnership") today issued a press
release reporting its first quarter results. The Partnership is furnishing the
press release, attached as Exhibit 99.1, pursuant to Item 9 and Item 12 of Form
8-K. The Partnership is also furnishing pursuant to Item 9 its estimates of
certain operating and financial results for the second quarter of 2003. In
accordance with General Instruction B.2. of Form 8-K, the information presented
under this Item 9, including Exhibit 99.1, shall not be deemed "filed" for
purposes of Section 18 of the Securities Act of 1934, as amended, nor shall it
be deemed incorporated by reference in any filing under the Securities Act of
1933, as amended, except as expressly set forth by specific reference in such a

Full Year 2003 Estimates

     The Partnership provided its estimates for the full year 2003 on Form 8-K
on February 26, 2003. Management believes that the assumptions and overall
estimates for EBITDA and Net Income contained within that filing remain
reasonable based on information known to us as of April 24, 2003. In March 2003,
we issued 2.6 million common units as part of an equity offering in order to
optimize our capital structure. This issuance increases the number of units
outstanding from 49.6 million units to 52.2 million units. Such equity offering
was not included in the assumptions contained in the February 26, 2003 8-K.
Accordingly, the increase in the number of units will have a dilutive effect on
per-unit measures.

Disclosure of Second Quarter 2003 Estimates

     The following table reflects the Partnership's range of current estimates
of certain results for the second quarter of 2003. These estimates are based on
assumptions and estimates that management believes are reasonable based on
currently available information; however, management's assumptions and our
future performance are both subject to a wide range of business risks and
uncertainties, so we cannot assure you that these goals and estimates can or
will be met. Please refer to the information under the caption "Forward-Looking
Statements and Associated Risks" below. These risks and uncertainties could
cause our actual results to differ materially from those in the following table.
The estimates set forth below are given as of the date hereof, based on
information known to us as of April 24, 2003. EBIT and EBITDA are non-GAAP
financial measures, and are reconciled in the table below to Net Income, the
most directly comparable GAAP measure. EBIT and EBITDA are presented because
management believes they provide additional information with respect to both the
performance of our fundamental business activities, as well as our ability to
meet our future debt service, capital expenditures, and working capital
requirements. Management also believes that debt holders commonly use EBITDA to
analyze company performance.

Notes and Assumptions:

1.   EBITDA means Earnings Before Interest, Taxes, Depreciation, and
     Amortization. EBIT means EBITDA less Depreciation and Amortization. The
     forecast presented above does not include assumptions or projections with
     respect to potential gains or losses related to SFAS 133, as there is no
     accurate way to forecast these potential gains or losses. The potential
     gains or losses related to SFAS 133 could materially change reported net
     income (related primarily to non-cash, mark-to-market gains or losses).
     Gross margin excludes depreciation.

2.   Pipeline Gross Margin. Pipeline volume and tariff estimates are based on
     historical operating performance and our outlook for future performance.
     Actual results could vary materially depending on volumes that are shipped.
     Average pipeline volumes are estimated to be approximately 845,000 barrels
     per day for the second quarter of 2003, with Outer Continental Shelf (OCS)
     volumes estimated to make up approximately 7% of these volumes, or
     approximately 60,000 barrels per day (compared to 1Q03 volumes of 59,000
     barrels per day). Volumes on Basin Pipeline for the second quarter are
     forecast at approximately 260,000 barrels per day (compared to 1Q03 volumes
     of 210,000 barrels per day). Revenues are forecast using these volume
     assumptions, current tariffs and estimates of operating expenses, each of
     which management believes are reasonable. A 5,000 barrel per day variance
     in OCS volumes would have an approximate $0.8 million effect on tariff
     revenue for the quarter and an approximate $3.1 million effect on an
     annualized basis. An average 25,000 barrel per day variance in the Basin
     Pipeline System, which is equivalent to an approximate 10% volume variance
     on that pipeline system, would have an approximate $0.9 million effect on
     tariff revenue for the quarter and an approximate $3.8 million effect on an
     annualized basis.

3.   Gathering, Marketing, Terminalling and Storage Gross Margin. Forecast
     volumes for Gathering & Marketing are approximately 505,000 barrels per day
     (approximately 440,000 barrels per day of lease gathering) for the second
     quarter of 2003 (compared to 1Q03 volumes of 503,000 barrels per day
     including 434,000 barrels per day of lease gathering). Gross margin
     excluding depreciation is forecast using these volume assumptions and
     estimates of unit margins and operating expenses, each of which management
     believes are reasonable. A 5,000 barrel per day variance in lease gathering
     volumes would have an approximate $0.2 million effect on gross margin and
     an approximate $0.9 million effect on an annualized basis. A variance in
     bulk purchases would have a substantially lower effect on gross margin as
     these volumes carry lower margins than our lease gathering business.

4.   General and Administrative Expense. G&A expense is forecast to be between
     $12.2 million and $12.6 million for the second quarter of 2003. This is
     based on current and forecast staffing levels and administrative

5.   Interest Expense. Second quarter interest expense is forecast to be between
     $8.8 million and $9.0 million assuming an average debt balance of
     approximately $550 million and an average interest rate of approximately
     6.4%, including our fixed rate debt, current interest rate hedges on
     floating rate debt and commitment fees. The forecast is based on estimated
     cash flow, current distribution rates, planned capital projects, planned
     sales of surplus equipment, forecast timing of collections and payments,
     and forecast levels of inventory and other working capital sources and
     uses, each of which management believes is reasonable.

6.   Depreciation & Amortization. Depreciation and amortization is forecast
     based on our existing depreciable assets and forecast capital expenditures.
     Depreciation is computed using the straight-line method over estimated
     useful lives which range from 5 years for office property and equipment to
     40 years for certain crude oil terminals and facilities. Crude oil
     pipelines are depreciated over 30 years.

7.   Units Outstanding. Our forecast is based on the 52,222,748 units currently
     outstanding. There are no dilutive securities or options issued or

8.   Net Income per Unit. Net income per limited partner unit (basic and
     diluted) is calculated by dividing the net income allocated to limited
     partners by the weighted average units outstanding during the period. As
     noted below, the net income allocated to limited partners is impacted by
     the income allocated to the general partner and the amount of the incentive
     distribution paid to the general partner.

9.   Potential Effect of Changes in Capital Structure. Interest expense, net
     income and net income per unit estimates are based on our capital structure
     as of April 24, 2003. In keeping with our established financial growth
     strategy of financing acquisitions using a balance of equity and debt, we
     anticipate that we will issue equity in order to reduce a portion of any
     debt associated with any future acquisitions. Depending on the terms, any
     such equity issuance may dilute the net income per unit forecasts included
     in the foregoing table. In addition, we intend to monitor debt capital
     market conditions and may in the future issue additional senior unsecured
     notes, which may bear interest costs greater than the amount included in
     the foregoing guidance. Accordingly,

     the foregoing financial results and per unit estimates will change,
     depending on the timing and the terms of any debt or equity we actually
     issue. Additionally, financing transactions may result in our retiring some
     of our outstanding debt, which could result in a charge to earnings of any
     unamortized debt issuance costs. We have not included any such potential
     charge in our forecast.

10.  Net Income to Limited Partners. The amount of income allocated to our
     limited partnership interests is 98% of the total partnership income after
     deducting the amount of the general partner's incentive distribution. Based
     on a $2.20 annual distribution level and the current units outstanding, our
     general partner's distribution is forecast to be approximately $7.4 million
     annually, of which $5.1 million is attributed to the incentive distribution
     rights. The amount of the incentive distribution changes based on the
     number of units outstanding and the level of the distribution on the units.

11.  Capital Expenditures. Expansion capital expenditures are forecast to be
     approximately $26 million for the second quarter. Maintenance capital
     expenditures are forecast to be approximately $2.5 million for the second
     quarter of 2003.

12.  Although acquisitions comprise a key element of our growth strategy, these
     results and estimates do not include any assumptions or forecasts for any
     material acquisitions that may be made after the date hereof.
