                                       3



Notes:

     1.   Estimated production volumes. Production estimates are based on
          historical operating performance and trends and the Company's 2002
          capital budget and assume that market demand and prices for oil and
          gas will continue at levels that allow for profitable production of
          these products.

          SEC Staff Accounting Bulletin 101 ("SAB 101") requires that revenue
          from crude oil production be recognized as the volumes are sold versus
          when produced. The location of our Florida properties and the timing
          of the barges that transport the crude oil to market cause reported
          sales volumes to differ from production volumes. Actual timing of
          sales volumes is difficult to predict. Reported sales volumes will
          differ from the production estimates provided. The Florida crude oil
          is typically sold in shipments of approximately 130,000-140,000
          barrels (100,000 barrels net to the Company's interest) and typically
          occurs every 40-50 days.

     2.   Estimated oil price differentials. The Company's realized wellhead
          crude oil price is lower than the NYMEX index level as a result of
          area and quality differentials. The Company has locked in a fixed
          price differential to NYMEX on approximately 65% of its production for
          the fourth quarter of 2002.

     3.   General and administrative. For purposes of calculating upstream unit
          G&A, we exclude noncash compensation expense related to stock options
          and nonrecurring items from the calculation. For the fourth quarter of
          2002 noncash compensation expense is estimated at $400,000.

     4.   DD&A - oil and gas. The Company's DD&A rate for the first nine months
          of 2002 is $3.10 per BOE. The fourth quarter DD&A rate will be
          adjusted based on year-end 2002 proved reserve volumes. For estimate
          purposes we are utilizing the $3.10 rate for the fourth quarter.

     5.   Equity in earnings of Plains All American Pipeline, L.P. ("PAA"). The
          Company's equity in earnings from PAA is based on guidance provided by
          PAA in its Form 8-K filed with the SEC on October 29, 2002, and the
          Company's aggregate ownership interest, as adjusted for general
          partner incentive distributions. As of the date hereof, the Company
          has an aggregate ownership interest of approximately 25%, consisting
          of (i) a 44% ownership stake in the general partner interest and
          incentive distribution rights, (ii) 45%, or approximately 4.5 million,
          of the subordinated units and (iii) 24%, or approximately 7.9 million
          of the common units (including the Class B common units). PAA's Form
          8-K provides guidance of $17.8 million to $20.1 million for its fourth
          quarter 2002 net income.

     6.   Interest expense. The Company's interest expense will consist of
          interest on:

          a.   $200 million of 8.75% Senior Subordinated Notes issued by our
               wholly owned subsidiary, Plains Exploration & Production Company
               ("PXP"). The notes were issued at 98.376% of par, and interest
               expense for the fourth quarter of 2002 will include $52,000 for
               the amortization of the original issue discount.

          b.   Amounts outstanding under PXP's $300 million revolving credit
               facility ("Credit Facility"). The Credit Facility provides for
               grid pricing at LIBOR or Prime at PXP's



                                       4



          option plus a margin based on the percentage of the borrowing base
          then being utilized as follows:

                                              25%          greater      greater
                           less than 25%     to 50%        than 50%     than 75%
    LIBOR Loans               1.375%         1.500%         1.625%       1.750%
    Prime Loans               0.125%         0.250%         0.375%       0.500%
    Commitment Fee            0.375%         0.375%         0.500%       0.500%


     c.   The Company has a three-year interest rate swap agreement under which
          it receives LIBOR and pays 3.9% on a notional amount of $7.5 million.

     d.   The Company estimates it will capitalize approximately
          $500,000-$600,000 of interest during the fourth quarter of 2002.

7.   The Company estimates that fourth quarter results will include
     approximately $650,000-$750,000 of expenses related to the terminated
     initial public offering of PXP. Total costs of the offering including
     amounts recognized in the third quarter are estimated to be approximately
     $2.4-$2.5 million.

8.   Book Tax Rate. The Company's book tax rate is based on a Federal rate of
     35% and an estimated combined foreign and state rate of 6%. The foreign tax
     is attributable to the Canadian operations of PAA. The Company's deferred
     and current tax rates are based on current estimates of taxable income and
     utilization of net operating loss carryforwards.

9.   Weighted average equivalent shares outstanding. Estimated basic shares
     outstanding are based on shares outstanding on September 30, 2002, net of
     treasury shares. Estimated diluted shares are based on basic shares
     outstanding, plus shares issuable upon conversion of preferred stock and
     outstanding options and warrants utilizing the treasury stock method for
     the options and warrants assuming a $25.00 average price for the Company's
     common stock.

10.  Distributions from Plains All American Pipeline, L.P. The estimated cash
     distributions are based on PAA's $0.5375 per unit quarterly distribution
     ($2.15 on an annual basis) that was declared in October 2002. The amount
     presented reflects estimated cash to be received from PAA and has not been
     adjusted for cash taxes.
