                                       3


Notes:

1.  Estimated Sales Volumes. Production estimates are based on historical
    operating performance and trends and the Company's 2001 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. Certain of the
    Company's operations in California that have interruptible electrical
    contracts have been adversely impacted by electrical service interruptions.
    The Company estimates that its oil and gas production for the first nine
    months of 2001 was adversely affected by approximately 60,000 BOE, as a
    result of such interruptions. Although under recent regulatory rulings the
    Company believes that its operations will only be affected if rolling
    blackouts occur and the Company has made operational changes to mitigate the
    effects of electrical interruptions, there can be no assurance that
    operations will not be adversely impacted in the future by the California
    power market.

    SEC Staff Accounting Bulletin 101 ("SAB 101") requires that revenue from
    crude oil production be recognized as the volumes are sold versus when
    produced. Due to the location of the Company's Florida properties and the
    transportation issues involved, reported sales volumes are impacted by the
    timing of the barges that transport the crude oil. The Florida crude is
    typically sold in shipments that range from 130,000 to 180,000 barrels.

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 estimated 2001 production volumes. Fourth
    quarter estimated differentials by area are: Onshore California - $4.70 per
    barrel, Offshore California - $6.90 per barrel, Florida - $14.60 per barrel,
    and Illinois - $1.00 per barrel and are based on current market conditions.
    The estimated hedging gain (loss) is calculated based on the NYMEX prices
    presented and the Company's current crude oil hedge positions.

3.  Operating Costs per BOE. Production expenses (including production and ad
    valorem taxes) averaged $7.01 per BOE in 2000. The Company estimates that
    production expenses will average $7.25 - $7.50 per BOE during the fourth
    quarter of 2001, primarily due to increased electricity and fuel related
    expenses. Unit G&A costs exclude non cash compensation expense. DD&A per BOE
    is based on our year-end 2000 proved reserve volumes. This rate will be
    adjusted for the fourth quarter based on year-end 2001 proved reserve
    volumes.

4.  Other Income (Expense). Equity in earnings of Plains All American Pipeline,
    L.P. (NYSE: PAA) is based on guidance provided by PAA in its November 7,
    2001 earnings release conference call and an aggregate ownership interest of
    approximately 29%, 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. The Company's common
    ownership has been adjusted to reflect PAA's 4.5 million unit equity
    offering, which was announced in October 2001. The Company will recognize a
    noncash gain in the fourth quarter as a result of the PAA offering.

    Estimated interest expense consists of interest expense on our $275 million
    of subordinated notes, net of capitalized interest of approximately $0.9
    million per quarter and estimates of

                                       4


    amounts outstanding on our revolving credit facility. The Company incurs a
    non-use fee of 3/8ths of 1% per annum on its $225 million revolving credit
    facility.

5.  Book Tax Rate. The Company's book tax rate is based on an adjusted Federal
    rate of 33% and an estimated combined foreign and state rate of 7%. 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.

6.  Equivalent weighted average shares outstanding. Estimated basic weighted
    average shares outstanding are based on approximately 24.3 million shares
    outstanding, net of treasury shares, as of September 30, 2001, as adjusted
    for treasury shares repurchased through October 31, 2001. During October, we
    repurchased approximately 1 million shares of our common stock. Estimated
    diluted shares are based on the estimated weighted average 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 the Company's average common stock price for
    the third quarter of 2001.

7.  Distributions from Plains All American Pipeline, L.P. The fourth quarter
    cash distribution is based on PAA's recently declared $.5125 per unit
    distribution. The amount presented reflects estimated cash payments to be
    received from PAA and has not been adjusted for cash taxes attributable to
    the Company's equity in earnings of PAA.
