 (b)  PRO FORMA FINANCIAL INFORMATION

      UNAUDITED PRO FORMA CONDENSED FINANCIAL STATEMENTS

          The following unaudited pro forma condensed financial statements have
      been prepared to illustrate the estimated effect of the acquisition of
      Gulf Canada Resources Limited (Gulf Canada) on Conoco Inc. (Conoco) under
      the purchase method of accounting. The unaudited pro forma condensed
      balance sheet assumes that the transaction was consummated on June 30,
      2001. The unaudited pro forma condensed statements of income for the year
      ended December 31, 2000 and the six months ended June 30, 2001 assume that
      the transaction was consummated on January 1, 2000. The unaudited pro
      forma condensed statement of income for the year ended December 31, 2000
      also gives effect to the acquisition (that closed effective November 6,
      2000) of Crestar Energy Inc. (Crestar) by Gulf Canada as if the
      acquisition had occurred on January 1, 2000. The unaudited pro forma
      condensed financial statements should be read in conjunction with the
      historical financial statements of Conoco and Gulf Canada, including the
      notes thereto, included elsewhere in this Current Report on Form 8-K/A.
      The unaudited pro forma condensed financial statements do not reflect any
      anticipated cost savings or any synergies that are anticipated to result
      from the Gulf Canada acquisition as there can be no assurance that any
      such cost savings or synergies will occur.

          These financial statements do not purport to represent what the
       results of operations or financial position of Conoco would actually have
       been if the acquisition had in fact occurred on such dates or project the
       results of operations or financial position of Conoco for any future date
       or period. Additionally, the unaudited pro forma condensed statements of
       income exclude non-recurring charges made in the third quarter of 2001
       resulting from the consummation of the transaction. These unaudited pro
       forma condensed financial statements are presented in accordance with
       U.S. GAAP under the successful efforts method of accounting for oil and
       gas properties.

                                       1


   This Current Report on Form 8-K/A includes forward-looking statements within
the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the
Securities Exchange Act of 1934.  You can identify these forward-looking
statements by the words "expects," "intends," "plans," "projects," "believes,"
"estimates" and similar expressions.  These statements are not guarantees of
future performance, involve certain risks, uncertainties and assumptions we
cannot predict, and are based upon assumptions as to future events that may not
prove accurate.  Among the factors that could cause such differences are:

  .  changes in crude oil and natural gas prices;

  .  changes in refining and marketing margins;

  .  potential failure to achieve, and potential delays in achieving, expected
     reserve or production levels from existing and future oil and gas
     development projects due to operating hazards, drilling risks and the
     inherent uncertainties in interpreting engineering data relating to
     underground accumulations of oil and gas;

  .  unsuccessful exploratory drilling activities;

  .  failure of new products and services to achieve market acceptance;

  .  unexpected delays and difficulties in constructing or repairing company
     manufacturing and refining facilities;

  .  unexpected difficulties in manufacturing, transporting or refining
     synthetic crude oil;

  .  general domestic and international economic and political conditions;

  .  the ability to meet government regulations;

  .  potential disruption or interruption of our facilities due to accidents or
     political events;

  .  international monetary conditions and exchange controls;

  .  liabilities for remedial actions under environmental regulations;

  .  liability resulting from litigation; and

  .  changes in tax and other laws applicable to our business.

1.   BASIS OF PRESENTATION

     The unaudited pro forma condensed statements of income of Conoco for the
year ended December 31, 2000, and the six months ended June 30, 2001, and the
unaudited pro forma condensed balance sheet as of June 30, 2001 (collectively
the unaudited pro forma condensed financial statements) have been prepared to
illustrate the estimated effect of the acquisition of Gulf Canada on Conoco
under the purchase method of accounting. The unaudited pro forma condensed
statements of income have been prepared as if the acquisition of Gulf Canada by
Conoco had occurred on January 1, 2000. The unaudited pro forma condensed
statement of income for the year ended December 31, 2000 also gives effect to
the acquisition (that closed effective November 6, 2000) of Crestar by Gulf
Canada as if the acquisition had occurred on January 1, 2000. The unaudited pro
forma condensed balance sheet has been prepared as if the acquisition had
occurred on June 30, 2001. The unaudited pro forma condensed financial
statements should be read in conjunction with the historical financial
statements of Conoco and Gulf Canada, including the notes thereto, included
elsewhere in this Current Report on Form 8-K/A.

     The unaudited pro forma condensed financial statements do not purport to
represent what the results of operations or financial position of Conoco would
actually have been if the acquisition had in fact occurred on such dates or to
project the results of operations or financial position of Conoco for any future
date or period.  Additionally, the unaudited pro forma condensed statements of
income exclude non-recurring charges made in the third quarter of 2001 resulting
from the consummation of the transaction.  The pro forma adjustments are based
upon currently available information and contain certain estimates and
assumptions.  Management believes the estimates and assumptions provide a
reasonable basis for presenting the significant effects of the acquisition, and
that the pro forma adjustments give appropriate effect to these estimates and
assumptions and are properly applied in the unaudited pro forma condensed
financial statements. The purchase price allocation is subject to changes as
additional information becomes available including the identification and
valuation of intangible assets. Management does not believe the final purchase
price allocation will differ materially from the estimated purchase price
allocation or that any adjustments to identifiable intangible assets would
materially affect related statement of income amortization expense. These
unaudited pro forma condensed financial statements are presented in accordance
with U.S. GAAP under the successful efforts method of accounting for oil and gas
properties.

2.   PRO FORMA ADJUSTMENTS

     The following is a description of each of the pro forma adjustments.

     (a) Unaudited Pro Forma Condensed Statements of Income

         1.  Incremental depreciation, depletion and amortization expense for
             Gulf Canada and Crestar based on the step-up to estimated fair
             value of the assets assuming the acquisition occurred on January 1,
             2000. Oil and gas properties are depreciated on a unit-of-
             production basis using estimated proved reserve quantities
             attributable to Gulf Canada.

         2.  Additional pro forma interest expense related to the borrowing of
             $4,500 necessary to fund the Gulf Canada acquisition. This entry
             assumes that the borrowing occurred on January 1, 2000. Interest
             expense calculations are based on Conoco's $4,500 senior unsecured
             364-day bridge credit facility used to fund the acquisition.
             Interest expense was calculated using an effective interest rate of
             approximately 4.76 percent. This rate was based on a July 1, 2001
             LIBOR three-month rate of approximately 3.83 percent. A 1/8th
             percent change in the effective interest rate would change interest
             expense by $6 for the year ended December 31, 2000 and $3 for the
             six months ended June 30, 2001. Conoco intends to refinance the
             364-day bridge credit facility of $4,500 in the capital markets
             prior to its expiration.

         3.  Incremental undeveloped leasehold amortization expense based on
             the estimated fair value of the undeveloped leaseholds acquired.
             During 2000, Gulf Canada recorded an impairment of undeveloped
             leaseholds, which has been reflected in the fair value allocated by
             Conoco as of June 30, 2001. This resulted in a pro forma adjustment
             to decrease amortization expense in the pro forma condensed income
             statement for the year ended December 31, 2000.

                    (DOLLARS IN MILLIONS, EXCEPT PER SHARE)


         4.  Income tax benefit related to purchase price adjustments, which was
             calculated using a blended statutory rate of 43 percent for cost
             and expense items with the exception of interest expense, which was
             calculated using a rate of 58 percent reflecting the deductibility
             of interest expense in both Canada and the U.S.

         5.  Estimated income effects of the Crestar acquisition by Gulf Canada
             for the first ten months of 2000. Gulf Canada purchased Crestar
             effective November 6, 2000. The historical consolidated financial
             statements of Crestar were prepared under Canadian GAAP and in
             Canadian dollars. The Crestar statement of income for the period
             ended November 5, 2000 has been converted to U.S. GAAP using the
             successful efforts method of accounting for oil and gas properties
             and converted to U.S. dollars using the average exchange rate of
             approximately .69 for the period ended November 5, 2000.

         6.  Recognition of Gulf Canada's preferred stock dividend. Gulf Canada
             reflected preferred stock in the stockholders' equity section of
             the balance sheet. Conoco reflects these shares as a minority
             interest as after the acquisition such shares represent preferred
             stock of a subsidiary.

     (b) Unaudited Pro Forma Condensed Balance Sheet as of June 30, 2001

         1.  Adjustment primarily reflects an asset as of June 30, 2001
             associated with cash collected by Gulf Canada between the July 1,
             2001 accounting date of the business combination and the July 16,
             2001 effective date for stock options exercised by Gulf Canada
             employees. The shares issued upon exercise of these options were
             issued and outstanding as of July 16, 2001 and therefore were
             shares purchased by Conoco at the acquisition date.

         2.  Reversal of Gulf Canada's historical property, plant and equipment
             balances and the related accumulated depreciation, depletion and
             amortization.

         3.  Estimated fair value of Gulf Canada's property, plant and
             equipment. Proved properties were valued at $4,192, unproved
             properties at $1,526 and other properties and equipment at $97.

         4.  Goodwill associated with the acquisition of Gulf Canada pursuant to
             the purchase method of accounting. Goodwill will be reviewed for
             impairment under the rules of Statement of Financial Accounting
             Standards (SFAS) No. 121, "Accounting for the Impairment of Long-
             lived Assets and for Long-lived Assets to be Disposed of," until
             adoption of SFAS No. 142, "Goodwill and Other Intangible Assets" on
             January 1, 2002.

         5.  This adjustment primarily relates to the reversal of deferred debt
             issuance costs recorded on Gulf Canada's historical financial
             statements. Gulf Canada's existing debt is adjusted to fair value.

         6.  Reflects preliminary assessment of fair value of identifiable
             intangible assets of $7.

         7.  Conoco incurred additional debt to fund the Gulf Canada
             acquisition. Conoco executed a $4,500 senior unsecured 364-day
             bridge credit facility on June 29, 2001. The total amount of the
             facility was drawn on July 16, 2001. The $4,500 debt is reflected
             as $650 in long-term debt based on Conoco's five-year committed
             credit facility with over two years remaining. The balance of
             $3,850 is reflected as short-term debt in other current
             liabilities. Conoco intends to refinance the 364-day bridge credit
             facility of $4,500 in the capital markets prior to its expiration.

         8.  Additional debt incurred to fund the Gulf Canada acquisition.

             contracts to their estimated fair values and the accrual of

             primarily Petrovera Resources, to estimated fair values.

        11.  Reflects the pro forma deferred income tax effect of the fair value
             adjustments related to the merger in accordance with the purchase
             method of accounting.

        12.  Adjustment of Gulf Canada's historical liabilities primarily to
             reflect the reversal of abandonment liabilities, which are included
             in the fair values of the producing oil and gas properties
             acquired.

        13.  Elimination of Gulf Canada's historical stockholders' equity in
             accordance with the purchase method of accounting.

        14.  Adjust Gulf Canada's existing debt to fair value.

             section of the balance sheet. Conoco reflects these shares as a
             minority interest as after the acquisition such shares represent
             preferred stock of a subsidiary.

  these financial statements, this amount has been grouped with net property,
  plant and equipment.

    The following adjustments are necessary to restate Gulf Canada's historical
financial statements from Canadian GAAP to U.S. GAAP and conform Gulf Canada's
presentation to Conoco's presentation.

Canadian GAAP to U.S. GAAP adjustments in Canadian dollars

    1.  Under U.S. GAAP, unrealized gains or losses arising on translation of
        long-term liabilities in foreign funds would be included in earnings in
        the period in which they arise. The capitalized balance on Gulf Canada's
        balance sheet of such losses was $75 at June 30, 2001 and $60 at
        December 31, 2000.

    2.  Additional pension and post-retirement expenses of $22 for the year
        ended December 31, 2000 and an additional liability of $10 at December
        31, 2000 and June 30, 2001, recognized under U.S. GAAP.

    3.  U.S. GAAP requires that impaired assets (Petrovera Resources) be written
        down to their fair value, rather than undiscounted future cash flows
        from use. Accordingly, Gulf Canada would have recognized additional
        impairment losses of $46 in 2000 and $123 in 1998, which in turn lowers
        depreciation expense by $8 in 2001 and $14 in 2000.

    4.  The related tax impacts of all U.S. GAAP adjustments.

    5.  Gulf Canada accounts for certain companies with less than 100 percent
        ownership using proportionate consolidation, whereas under U.S. GAAP,
        these companies would be accounted for under the equity method of
        accounting. There is no profit and loss impact to these line item
        reclassifications.

    6.  Under U.S. GAAP, Gulf Canada would have been required to adopt SFAS No.
        133, "Accounting for Derivative Instruments and Hedging Activities" and
        SFAS No. 138, "Accounting for Certain Derivative Instruments and Certain
        Hedging Activities," effective January 1, 2001. Gulf Canada has not
        designated any of the derivatives it held at January 1, 2001 as hedges
        under the provisions of these standards. The adoption of these standards
        would have resulted in a pre-tax gain of $51 for the period ended
        June 30, 2001 (exclusive of the cumulative effect adjustment) and the
        recognition of $3 in assets and $62 in liabilities as of June 30, 2001.

    7.  Gulf Canada reported revenues net of purchase costs, transportation
        costs and marketing fees. This entry is made to reflect revenues gross
        and to reflect purchase costs, transportation costs and marketing fees
        in the individual line items of cost of goods sold, operating expenses
        and general and administrative expenses, respectively. There is no
        profit and loss impact to these line item reclassifications.


Conforming adjustments to reclassify certain amounts in Gulf Canada's historical
financial statements to conform to Conoco's presentation

    8.  Gulf Canada reflected undeveloped leasehold amortization as
        depreciation, depletion and amortization expense whereas Conoco reflects
        undeveloped leasehold amortization as exploration expense, which is
        consistent with U.S. oil and gas industry practices.

    9.  Gulf Canada reflected property taxes as other operating expenses whereas
        Conoco reflects property taxes as taxes other than income taxes.

   10.  Gulf Canada reflected net (gain) loss on asset disposals and provision
        for other losses in a cost and expense caption. Conoco would reflect
        this activity in other revenues.

   11.  Conoco reflects pension settlements in operating costs whereas Gulf
        Canada reported these costs separately.

INFORMATION ON SYNCRUDE PROJECT NOT INCLUDED ABOVE

  In addition to conventional liquids and natural gas proved reserves, Gulf
Canada has a 9.03 percent interest in the Syncrude project in Canada.  Conoco
views the reserves associated with this project and their development as an
integral part of total upstream operations.  However, U.S. Securities and
Exchange Commission regulations define these reserves as mining related and not
a part of conventional oil and gas reserves.  The following is Gulf Canada's
share of reserves and estimated standardized measure of discounted future net
cash flows associated with the Syncrude project at December 31, 2000:
