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 only on information known to us as of October 28, 2002.

Notes and Assumptions:

1.   EBITDA means Earnings Before Interest, Taxes, Depreciation, Amortization
     and other non-cash items. EBIT means EBITDA less Depreciation and
     Amortization. Adjusted income means net income before unusual or
     non-recurring items and the impact of Standards of Financial Accounting
     Statement (SFAS) 133, "Accounting for Derivative Instruments and Hedging
     Activities." The historical results presented in the table do not include
     the impact of any unusual or non-recurring items or SFAS 133. The effect of
     these excluded items would be to reduce adjusted income, EBITDA and EBIT by
     approximately $2.1 million, and would reduce adjusted income per unit by
     $0.04.The forecast presented above does not include any assumptions or
     projections with respect to any potential gains or losses related to SFAS
     133 or EITF 98-10. The potential gains or losses related to SFAS 133 or
     EITF 98-10 could materially change reported net income.

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 900,000 barrels
     per day for the fourth quarter of 2002, with Outer Continental Shelf (OCS)
     volumes estimated to make up approximately 7% of these volumes, or
     approximately 68,000 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 (approximately 7%) would have an approximate
     $800,000 effect on EBITDA for the fourth quarter and an approximate $3.2
     million effect on an annualized basis. An average 25,000 barrel per day
     variance in the Basin Pipeline System, equivalent to an approximate 10%
     volume reduction on that pipeline system, would have an approximate
     $850,000 effect on EBITDA for the fourth quarter and an approximate $3.4
     million effect on an annualized basis.

3.   Gathering, Marketing, Terminalling and Storage Gross Margin. Forecast
     volumes for Gathering & Marketing are approximately 485,000 barrels per day
     for the fourth quarter of 2002, consistent with our current volumes. Gross
     margin is forecast using these volume assumptions and estimates of unit
     margins and operating expenses, each of which management believes are
     reasonable.

4.   General and Administrative Expense. G&A expense is forecast to be between
     $11.7 million and $11.8 million for the fourth quarter of 2002. Excluding
     acquisition related increases, the fourth quarter of 2002 includes
     approximately $600,000 of consultant and contractor related expenses
     attributable to accounting system enhancements and increased resources
     associated with an ongoing project to reprocess, validate and collect
     certain prior-year accounts receivable, which we expect to substantially
     complete over the next three months.

5.   Interest Expense. Fourth quarter interest expense is forecast to be between
     $8.7 million and $9.0 million assuming an average debt balance in the
     fourth quarter of 2002 of approximately $525 million and an average
     interest rate of approximately 6.8%, including our current interest rate
     hedges and commitment fees. The forecast is based on estimated cash flow,
     current distribution rates, planned capital projects, planned sales of
     surplus equipment, 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 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 49,577,748 units that are
     currently outstanding.

8.   Adjusted Income per Unit. Adjusted income per limited partner unit is
     calculated by dividing the adjusted income allocated to limited partners by
     the weighted average units outstanding during the period. As noted in
     number 10 below, the adjusted income allocated to limited partners is
     impacted by the amount of the incentive distribution paid to the general
     partner.

9.   Potential Effect of Changes in Capital Structure. Interest expense,
     adjusted income and adjusted income per unit estimates are based on our
     capital structure as of October 28, 2002. 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
     debt associated with any future acquisitions. Depending on the terms, any
     such equity issuance may dilute the adjusted income per unit forecasts
     included in the foregoing table. In addition, we have recently issued $200
     million of senior unsecured notes. 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 unamortized debt issuance costs associated with the
     retired debt. We have not included any such potential charge in our
     forecast.

10.  Adjusted Income to Limited Partners. The forecast is based on our current
     annual distribution of $2.15 per unit. The amount of adjusted income
     allocated to our limited partnership interests is 98% of the total
     partnership adjusted income less the amount of the general partner's
     incentive distribution. Based on a $2.15 annual distribution level and the
     current units outstanding, our general partner's incentive distribution is
     forecast to be approximately $4.0 million annually. 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. Total capital expenditures are estimated to be $8.3
     million for the fourth quarter of 2002. Of this amount, expansion capital
     is estimated to be $6.5 million during the fourth quarter. The expansion
     capital estimates are primarily attributable to the Phase III expansion at
     our Cushing Terminal and a pipeline loop on a portion of the Manito System
     in Canada. Maintenance capital is estimated to be $1.8 million for the
     fourth quarter.

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

13.  The results for the year are based on the year-to-date September 30, 2002
     actuals and our fourth quarter estimates.

Preliminary Estimates for Year 2003

     On July 24, 2002, we provided preliminary guidance for 2003 for EBITDA and
EBIT, which guidance incorporated information for the Shell West Texas assets.
We are currently in the process of developing our 2003 plan. We intend to update
this guidance upon completion of our annual plan for 2003. Pending that update
the following information updates our estimate of 2003 depreciation and
amortization resulting from an updated purchase price allocation for the Shell
West Texas assets. Such information also incorporates the impact of recent
changes in our capital structure resulting from equity and debt offerings
completed in the third quarter.

Adjusted Income Per Unit                       $1.46             $1.60

     The table above reflects the estimated EBITDA range as well as estimated
depreciation, amortization and interest expense for the full year 2003. Adjusted
income per unit is calculated assuming no change in units outstanding or
distribution ($2.15 per unit), as of October 28, 2002.

     We have not included in this table the effect of potential vesting of unit
grants under our Long-Term Incentive Plan, which permits the grant of restricted
units and unit options covering an aggregate of approximately 1.4 million units.
Approximately 1.0 million restricted units (and no unit options) have been
granted. A restricted unit grant entitles the grantee to receive a common unit
upon the vesting of the phantom unit. Subject to additional vesting
requirements, restricted units may vest in the same proportion as the conversion
of the partnership's outstanding subordinated units into common units. Certain
of the restricted unit grants contain additional vesting requirements tied to
the partnership

achieving targeted distribution thresholds, generally $2.10, $2.30 and $2.50 per
unit, in equal proportions.

     Under generally accepted accounting principles, we are required to
recognize an expense when the financial tests for conversion of subordinated
units and required distribution levels are met. The test associated with the
conversion of subordinated units to common units is set forth in the partnership
agreement and involves GAAP accounting concepts as well as complex and esoteric
cash receipts and disbursement concepts that are indexed to the minimum
quarterly distribution rate of $1.80 per limited partner unit.

     Because of this complexity, it is difficult to forecast when the vesting of
these phantom units will occur. However, at the current distribution level of
$2.15 per unit, assuming the subordination conversion test is met, the costs
associated with the vesting of up to approximately 820,000 units would be
incurred or accrued in the second half of 2003 or the first quarter of 2004. At
a distribution level of $2.30 to $2.49, the number of units would be
approximately 940,000. At a distribution level at or above $2.50, the number of
units would be approximately 1,030,000. We are currently planning to issue units
to satisfy the first 975,000 vested, and to purchase units in the open market to
satisfy any vesting obligations in excess of that amount. Issuance of units
would result in a non-cash compensation expense. Purchase of units would result
in a cash charge to compensation expense. The amount of the charge to expense
will be determined by the unit price on the date vesting occurs multiplied by
the number of units.

     Consistent with our acquisition strategy, we are continuously engaged in
discussions with potential sellers regarding the possible purchase by us of
midstream crude oil assets. Since 1998, we have completed 12 acquisitions for an
aggregate purchase price of $1.1 billion. We can give you no assurance that our
current or future acquisition efforts will be successful or that any such
acquisition will be completed on terms considered favorable to us. In addition,
the partnership routine incurs third party costs in connection with these
activities, which are capitalized and deferred pending final outcome of the
transaction. Deferred costs associated with successful transactions are
capitalized as part of the transaction, while deferred costs associated with
unsuccessful transactions are expensed at the time of such final determination.
We have not included any such potential charge in our forecast.

     Several regulatory and legislative initiatives have been introduced over
the past several months in response to recent events regarding accounting issues
at large public companies, resulting disruptions in the capital markets and
ensuing calls for action to prevent repetition of such events. The partnership
supports the actions called for under these initiatives and believes these steps
will ultimately be successful in accomplishing the stated objectives. However,
implementation of reforms in connection with such initiatives will add to the
costs of doing business for all publicly-traded entities, including the
partnership. Such costs will have an adverse impact on future income and cash
flow, especially in the near term as legal, financial and consultant costs are
incurred to analyze the new requirements, formalize current practices and
implement required changes to ensure the partnership maintains compliance with
these new rules. We are not able to estimate the magnitude of increase in our
costs that will result from such reforms.

     Our current capital structure is expected to change as a result of issuing
equity to fund subsequent future acquisitions, if any, and from the possible
issuance of additional senior unsecured notes. These financing transactions may
have a dilutive effect on adjusted income per unit. Additionally, financing
transactions may result in our retiring some of our outstanding debt, which
could result in a charge to earnings of unamortized debt issuance costs. We have
not included any such potential charge in our forecast.
