                BURLINGTON RESOURCES INC. RETIREMENT SAVINGS PLAN
                          NOTES TO FINANCIAL STATEMENTS

1.     PLAN DESCRIPTION

       General

       The following description of the Burlington Resources Inc. ("BR" or the
       "Company") Retirement Savings Plan (the "Plan") provides only general
       information. Participants should refer to the Plan Document for a more
       complete description of the Plan's provisions.

       The Plan is a trusteed, defined contribution plan, administered by a
       committee of BR executives, for participants of the employer companies BR
       and Burlington Resources Oil & Gas Company LP (formerly known as
       Burlington Resources Oil & Gas Company), which is a wholly-owned
       subsidiary of BR. The Plan is subject to the provisions of the Employee
       Retirement Income Security Act of 1974 ("ERISA"), as amended. The Plan's
       assets are held by Charles Schwab Trust Company and individual
       participant accounts are maintained by Charles Schwab Retirement Plan
       Services.

       Investments

       A participant may direct his or her contributions and account balances
       among the following investment funds.

       Company Stock Fund - Invested in common stock of BR.

       S&P 500 Institutional Index Fund - Invested in a diversified portfolio of
       common stock and other equity securities. This fund is managed to achieve
       results similar to those of the overall stock market as measured by the
       Standard & Poor's 500 Index.

       International Equity Fund - Invested primarily in the equity securities
       of companies based outside the United States of America.

       Balanced Fund - Invested 60% in equity securities, which attempt to
       mirror the Willshire 5000 Equity Index and 40% in high-quality bonds,
       which attempt to mirror the Lehman Brothers Aggregate Bond Index.

       Small-Cap Equity Fund - Invested at least 65% of its total assets in
       common stock, or other equity securities including preferred stocks,
       rights and warrants of the second 1,000 largest U.S. corporations.

       Growth Equity Fund - Invested primarily in common stocks of corporations
       that the trust advisor believes are undervalued and capable of generating
       strong earnings growth in the near term.

                                       4


       Large Capital Value Fund - Invested primarily in common stocks and other
       instruments convertible into common stock issued by large corporations.

       Global Equity Fund - Invested primarily in equity instruments issued by
       corporations from the U.S. and abroad.

       Stable Value Fund - Invested primarily in a diversified portfolio of
       investment contracts offered by major insurance companies and financial
       institutions.

       Small Cap Growth Fund - Invested primarily in common stocks of U.S. and
       foreign companies within the range of capitalizations of companies
       included in the Lipper, Inc. Small Cap category.

       Participants' Notes Receivable

       The Plan may make loans to actively employed participants of up to 50% of
       their account balance (excluding any Individual Retirement Account
       balance), subject to a minimum loan of $1,000 and a maximum loan of
       $50,000. The $50,000 limit is reduced by the participant's highest
       outstanding loan balance during the prior one-year period. Interest on
       loans accrues at 1% above the Wall Street Journal published prime rate,
       which is determined at the time the loan is taken, and remains fixed for
       the term of the loan. The repayment period may be from one to five years.
       Repayments are made through payroll deductions and are reinvested in Plan
       funds according to the borrowing participant's current investment
       elections. Loan balances due from terminated participants may be deemed
       distributed to the participants at the time his or her account balance is
       liquidated. During 2001, $395,149 of such distributions are included in
       participant withdrawals and distributions in the accompanying financial
       statements.

       Contributions

       A participant may elect to make regular semi-monthly pre-tax and/or
       after-tax contributions from 1% to 13% of his or her total eligible
       compensation. Pre-tax contributions are subject to an IRS limitation of
       $10,500. The Company matches up to 6% of total eligible compensation for
       a participant with less than 10 years of service and up to 8% of total
       eligible compensation for a participant with 10 or more years of service.
       In addition, a participant may make an approved rollover contribution
       from another qualified employee benefit plan. All regular Company and
       participant contributions are paid to the Plan's trustee semi-monthly,
       and allocated among the investment options consistent with participant
       investment elections.

       Vesting

       Participant accounts are 100% vested and nonforfeitable at all times.

       Participant Withdrawals and Distributions

       The Plan provides for several different types of withdrawals by
       participants. Participants may take in-service withdrawals of certain
       funds depending on their source. Upon the separation

                                       5


       from service, a participant's account balance may be distributed in a
       lump sum. A participant whose account balance exceeds $5,000 may elect a
       deferred distribution or installment payments over a period ending not
       later than April 1 of the year following the calendar year in which the
       participant attains age 70-1/2.

       Termination of the Plan

       While the Board of Directors of BR has not expressed any intention to do
       so, they may at any time terminate the Plan. Upon termination, the Plan's
       assets will be distributed to the participants on the basis of their
       account balances existing at the date of termination.

       Income Taxes

       The Plan has received a determination letter dated June 12, 2000, from
       the Internal Revenue Service advising that the Plan constitutes a
       qualified plan under Section 401(a) of the Internal Revenue Code and is
       therefore exempt from income taxes.

2.     ACCOUNTING POLICIES

       Principles of Reporting

       In accordance with generally accepted accounting principles ("GAAP"), the
       accounting records of the Plan are maintained on the accrual basis except
       for participant withdrawals and distributions, which are reported when
       paid. Amounts for benefit claims that have been processed and approved
       for payment prior to December 31, but not paid as of that date are
       reported on Form 5500 as withdrawals. No such unpaid claims exist at
       December 31, 2001 or 2000. The preparation of the Plan's financial
       statements in conformity with GAAP requires certain estimates and
       assumptions. Actual results could differ from estimates. Due to the level
       of risk associated with certain investment securities and the level of
       uncertainty related to changes in their value, it is at least reasonably
       possible that changes in the near term could materially affect the
       amounts reported in the Statement of Net Assets Available for Benefits.

       Investments

       The Plan's investments, except for its investment contracts, are stated
       at fair value. Investment contracts, which are fully benefit responsive,
       are stated at contract value. Fair value for investments other than
       participants' notes receivable is determined by quoted market prices.
       Participants' notes receivable are carried at original loan principal
       balance, less principal repayments which approximates fair value.

       Net appreciation (depreciation) in the fair value of the Plan
       investments, which consists of net realized and unrealized appreciation
       (depreciation), is presented in the Statement of Changes in Net Assets
       Available for Benefits. This appreciation (depreciation) is allocated to
       participants based upon their proportionate share of assets in each
       investment fund.

                                       6


       Cash and Cash Equivalents

       All short-term investments purchased with a maturity of three months or
       less are considered cash equivalents. Cash equivalents are stated at fair
       value.

       Dividend and Interest Income

       Dividend and interest income from investments are recorded as earned and
       allocated to participants based upon their proportionate share of assets
       in each investment fund.

       Administrative Expenses

       Certain administrative expenses and professional fees incurred by the
       Plan are paid by BR, including record keeping and trust fees.

3.     NET DEPRECIATION IN THE FAIR VALUE OF INVESTMENTS

       Following is a summary of the components of the net depreciation in the
       fair value of investments.

5.     INVESTMENT CONTRACTS

       The fair value of investment contracts as of December 31, 2001 and 2000
       was approximately $64,500,000 and $58,100,000, respectively. Fair value
       was determined using a discounted cash flow analysis assuming market
       rates for similar contracts. The average yield for these investment
       contracts during 2001 and 2000 was 5.82% and 6.50%, respectively. The
       crediting interest rates ranged from 2.44% to 8.75% and 5.13% to 7.50% at
       December 31, 2001 and 2000, respectively.

                        REPORT OF INDEPENDENT ACCOUNTANTS


To the Participants and Administrator of
Burlington Resources Inc. Retirement Savings Plan

In our opinion, the accompanying statement of net assets available for benefits
and the related statement of changes in net assets available for benefits
present fairly, in all material respects, the net assets available for benefits
of Burlington Resources Inc. Retirement Savings Plan (the "Plan") at December
31, 2001 and 2000, and the changes in its net assets available for benefits for
the year ended December 31, 2001 in conformity with accounting principles
generally accepted in the United States of America. These financial statements
are the responsibility of the Plan's management; our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with auditing standards
generally accepted in the United States of America which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule listed in the
accompanying table of contents on Page 1 is presented for the purpose of
additional analysis and is not a required part of the basic financial statements
but is supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. This supplemental schedule is the responsibility of the
Plan's management. The supplemental schedule has been subjected to the auditing
procedures applied in the audits of the basic financial statements and, in our
opinion, is fairly stated in all material respects in relation to the basic
financial statements taken as a whole.
