Retirement Savings Plan In our opinion, the accompanying statements 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, 2002 and 2001, and the changes in its net assets available for benefits for the year ended December 31, 2002, 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 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.

RETIREMENT SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2002 -------------------------------------------------------------------------------- 1. PLAN DESCRIPTION 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. GENERAL 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 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 in equity securities, which attempt to mirror the Willshire 5000 Equity Index and in high-quality bonds, which attempt to mirror the Lehman Brothers Aggregate Bond Index. Small-Cap Equity Fund Invested in common stocks, 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. Large Capital Value Fund Invested primarily in common stocks and other instruments convertible into common stock issued by large corporations. 4 BURLINGTON RESOURCES INC. RETIREMENT SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2002 -------------------------------------------------------------------------------- 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. ELIGIBILITY All employees are eligible to participate in the Plan beginning the first day of the month following full time employment, or upon completion of 1,000 hours of service. PARTICIPANT ACCOUNTS A separate account is maintained for each participant that reflects the participant's contributions and the participant's share of Company contributions and Plan investment income net of withdrawals. Each participant can authorize the transfer of account balances among funds or change investment options for future contributions. Appreciation (depreciation) is allocated to participants based upon their proportionate share of assets in each investment fund. PARTICIPANTS' NOTES RECEIVABLE The Plan may make loans to actively employed participants of up to 50 percent of their account balance (excluding any remaining Individual Retirement Account balance that was entered into prior to 1998), 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. Loans are secured by the balance in a participant's account. Interest on loans accrues at 1 percent 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. Interest rates ranged from 5.25 percent to 10.50 percent for the year ended December 31, 2002. The repayment period may be from 12-60 months. 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 are deemed distributed to the participants during the quarter following the quarter in which the last loan payment was made. During 2002, $397,251 of such distributions are included in participant withdrawals and distributions in the accompanying financial statements. There were no loans in default as of December 31, 2002 and 2001. CONTRIBUTIONS A participant may elect to make regular semi-monthly pre-tax and/or after-tax contributions from 1 percent to 13 percent of his or her total eligible compensation via regular payroll deduction. Pre-tax contributions are subject to an Internal Revenue Service (IRS) limitation of $11,000 for the 2002 plan year. The Company matches 100 percent of employee contributions up to 6 percent of total eligible compensation for a participant with less than 10 years of service and up 5 BURLINGTON RESOURCES INC. RETIREMENT SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2002 -------------------------------------------------------------------------------- to 8 percent 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, subject to IRS rules. 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 percent vested and nonforfeitable at all times. PARTICIPANT WITHDRAWALS AND DISTRIBUTIONS The Plan provides for in-service withdrawals by participants from certain funds depending on their source. Upon separation from service, a participant's account balance is either distributed as a lump sum or deferred until 70-1/2, at which time funds are to be distributed in a lump sum. A participant whose account balance exceeds $5,000 may elect to defer distribution until 70-1/2 but no later. TERMINATION OF THE PLAN While the Board of Directors of BR has not expressed any intention to do so, it 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 received a determination letter dated October 25, 2002, from the IRS 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. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BASIS OF ACCOUNTING 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, 2002 or 2001. USE OF ESTIMATES The preparation of the Plan's financial statements in conformity with GAAP requires certain estimates and assumptions by Plan management. Actual results could differ from estimates. RISKS AND UNCERTAINTIES 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. 6 BURLINGTON RESOURCES INC. RETIREMENT SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2002 -------------------------------------------------------------------------------- VALUATION OF 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 values for investments other than participants' notes receivable and cash are determined by quoted market prices. Participants' notes receivable are carried at original loan principal balance, less principal repayments, which approximates fair value. Cash is stated at account value. Investment transactions are recorded on a settlement date basis. CASH AND CASH EQUIVALENTS All short-term investments purchased with an original 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. BR paid approximately $242,000 and $212,000 for the years ended December 31, 2002 and 2001, respectively. 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 for the year ended December 31, 2002.

Fair value was determined using a discounted cash flow analysis assuming market rates for similar contracts. The average yield for these investment contracts during 2002 and 2001 was 5.22 percent and 5.82 percent, respectively. The crediting interest rates ranged from 1.43 percent to 7.65 percent and 2.44 percent to 8.75 percent at December 31, 2002 and 2001, respectively.
