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

       Small-Cap  Equity Fund -At least 65% of its total  assets are invested 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.

       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 first of the month  preceding the quarter in
       which the loan is taken.  The interest  rate is 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  particpants at the time his or her account balance is liquidated.
       During 2000, $1,213,038 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.

       Vesting

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

       Participants' 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  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.


                                       5



       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,  2000 or 1999.  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.

       Cash and Cash Equivalents

       All short-tem  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.

                        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, 2000 and 1999, and the changes in its net assets available for benefits for
 the year ended  December  31, 2000 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.
