4 INDEPENDENT AUDITOR'S REPORT To the Administrator of the Berry Petroleum Company Thrift Plan We have audited the accompanying statements of net assets available for benefits of the Berry Petroleum Company Thrift Plan as of December 31, 2002 and 2001, and the related statement of changes in net assets available for benefits for the year ended December 31, 2002. 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 in accordance with auditing standards generally accepted in the United States of America. Those standards 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. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of Berry Petroleum Company Thrift Plan as of December 31, 2002 and 2001 and the changes in 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. Our audits were made for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets (held at end of year) as of December 31, 2002, is presented for the purpose of additional analysis and is not required part of the basic financial statements, but is supplementary information required by the United States Department of Labor 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 take as a whole.

7 BERRY PETROLEUM COMPANY THRIFT PLAN NOTES TO FINANCIAL STATEMENTS Note 1. Plan Description The following description of the Berry Petroleum Company Thrift Plan (the "Plan") is provided for general information purposes only. Participants should refer to the Plan Agreement for more complete information. General The Plan is a defined contribution plan under Section 401(k) of the Internal Revenue Code (the "Code"). All employees of Berry Petroleum Company (the "Company") who have completed six months of service, as defined in the Plan Agreement, and who are not covered by a collective bargaining agreement with retirement benefits, are eligible to participate in the Plan. Contributions Employees who elect to participate in the Plan must contribute 6% of their annual earnings as a basic tax-deferred contribution. The Company matches 100% of this employee contribution. The Plan provides for a Company match in excess of 6% if certain financial results are achieved. Company matching contributions can range from 6% to 9% of eligible participating employee earnings for active participants in the Plan. Matching contributions were from 6% to 9% in both 2002 and 2001 and averaged approximately 6.83% and 7.25% for 2002 and 2001, respectively. The Plan allowed employees to contribute a maximum combined pre-tax and after-tax deferral of 60% as of May 1, 2002, up from a previous limit of 16%. Participant and employer contributions are subject to statutory limitations, which for 2002 were $11,000 pre-tax and $40,000 total for all employee and employer contributions. Employees who have attained the age of 50 by the end of the Plan year were eligible to make an additional catch- up contribution of $1,000 for 2002. Participants vest immediately in their contributions, and vesting in employer contributions is at a rate of 20% per year of service during the first five years of employment. Investment Funds The investment selections available to participants are as follows: Berry Petroleum Company Common Stock Spartan U.S. Equity Index Fund Managed Income Portfolio Fidelity U.S. Bond Index Fund Fidelity Contrafund Fidelity Freedom Income Fund Fidelity Diversified Fidelity Freedom 2000 Fund International Fund Fidelity Equity Income I Fund Fidelity Freedom 2010 Fund Fidelity Growth & Income Fund Fidelity Freedom 2020 Fund Fidelity Low Priced Stock Fund Fidelity Freedom 2030 Fund Fidelity Puritan Fund Fidelity Freedom 2040 Fund Contributions made by or on behalf of Plan participants are invested monthly and held under a trust agreement in one or more of the investment funds selected by the Plan Sponsor in accordance with the provisions of the Plan Agreement and as directed by the participants. Employees are able to choose to have their contributions invested in the Managed Income Portfolio, Berry Petroleum Company Common Stock 5

8 BERRY PETROLEUM COMPANY THRIFT PLAN NOTES TO FINANCIAL STATEMENTS Note 1. Plan Description, continued and a selection of mutual funds, currently at 14. With the maturity on December 31, 2001 of the last separate GIC contract, all of the funds allocated to the Blended Income Fund were moved to Fidelity's Managed Income Portfolio, a common collective trust, effective February 1, 2002. The Managed Income Portfolio is designed to preserve capital and achieve a competitive level of income over time while attempting to maintain a participant's unit value at one dollar per share, similar to a money market fund. The 14 mutual funds available for investments noted above are: Fidelity Contrafund seeks high capital appreciation, Fidelity Diversified International seeks capital appreciation investing in equity markets worldwide but mainly those in the Morgan Stanley EAFE Index, which excludes the United States, Fidelity Equity Income I is a stock fund seeking capital appreciation and dividend income that exceeds the yield of the Standard & Poors 500 Index ("S & P 500 Index"), Fidelity Growth & Income seeks long- term capital growth, current income and growth of income, consistent with reasonable investment risk, Fidelity Low Priced Stock seeks capital appreciation by investing mainly in low-priced common stocks (less than $35.00 at original purchase), Fidelity Puritan seeks as much income as possible, consistent with the preservation of capital, by investing in common stocks, bonds and preferred stock, Spartan U. S. Equity Index is a stock index fund that seeks investment results that correspond to the total return performance of the S & P 500 Index by duplicating the investment composition. Fidelity U. S. Bond Index seeks to provide investment results that correspond to the aggregate price and interest performance of the debt securities of the Lehman Brothers Aggregate Bond Index. Fidelity Freedom Income seeks a high level of current income with capital appreciation as a secondary objective. The Fidelity Freedom 2000, 2010, 2020, 2030 and 2040 mutual funds are designed to provide attractive long-term returns consistent with the targeted investment horizon. The Plan had group annuity contracts ("GICs") with John Hancock Mutual Life Insurance Company ("John Hancock") during 2001 and in prior years. All of the Plan's group annuity contracts were fully benefit responsive. Each account was credited with income determined at a fixed interest rate until maturity. These contracts are included in the financial statements at cash value at December 31, 2001 because the last contract matured on December 31, 2001. The following investments had values at December 31, 2002 and 2001 representing more than 5% of net assets available for Plan benefits: 2002 2001 Fidelity Managed Income Portfolio $ 5,444,806 $ - Blended Income Fund - 4,746,085 Fidelity Contrafund 1,545,417 1,744,808 Fidelity Low-Priced Stock 1,145,130 1,119,056 Fidelity Diversified International 822,059 859,990 Fidelity Growth & Income 808,021 932,406 Spartan U.S. Equity Index 767,638 876,582 Fidelity Equity Income I 628,882 751,693 6

9 BERRY PETROLEUM COMPANY THRIFT PLAN NOTES TO FINANCIAL STATEMENTS Note 1. Plan Description, continued The following table presents a summary of credited interest rates and average yield information for each of the GICs for the period shown: 2001 Credited Interest Average Issuer Rate Yield John Hancock Contract #2 6.17% due 12/31/2001 6.17% Participant Accounts Participant statements are prepared and distributed quarterly. However, the participant can access their account daily with Fidelity's Net Benefits online service. Each participant's account is credited with the participant's and the Company's contributions, in addition to the allocation of any Plan earnings or losses and forfeitures of terminated participants' nonvested accounts. Earnings or losses are allocated on a fund-by-fund basis. Allocations are based on the ratio of the participant's account balance in each mutual fund to the total assets of the mutual fund. Allocation of forfeitures is based on service units from 0 to 12 depending on months of service during the year. Only employees who are active participants at December 31 each year are eligible for the allocation of forfeitures to their accounts. Forfeitures allocated to participant accounts for the years ended December 31, 2002 and 2001 totaled $24,839 and $5,975, respectively. Participant Loans Participants are entitled to borrow from their vested account balances in amounts from $1,000 to $50,000, but not in excess of 50% of their vested account balances. Interest is computed based on the prime rate in the Wall Street Journal on the date of the application, plus 2%. A maximum of two loans can be outstanding at any one time and each loan must be repaid over a period of from 1 to 5 years. Each loan is supported by a promissory note with the participant's account balance as collateral. Hardship Withdrawals The Plan allows for hardship withdrawals to pay certain housing, health or education expenses if the participant does not have other funds available for these expenses. Internal Revenue Service ("IRS") regulations require that a participant cannot make contributions to the Plan for 6 months after taking a hardship withdrawal. In addition, participants will not receive matching contributions or forfeitures for the 6 months they are ineligible to participate in the Plan. 7

10 BERRY PETROLEUM COMPANY THRIFT PLAN NOTES TO FINANCIAL STATEMENTS Note 1. Plan Description, continued Payment of Benefits Upon termination of service due to retirement, death, disability or other reasons, the participant or beneficiary, in the case of death, can request withdrawal of his or her account equal to the value of the vested balance in the participant account, reduced by any unpaid loan balance. If desired, a participant can leave the account balance in the Plan until the participant attains age 70 and 1/2 unless the participant's vested account balance is less than $5,000, in which case the vested account balance would be distributed to the participant. Plan Termination Although it is anticipated that the Plan will remain in effect indefinitely, the Company has the right to discontinue its contributions and terminate the Plan subject to the provisions of the Employee Retirement Income Security Act of 1974. In the event of complete or partial termination of the Plan, participants become 100% vested in the employer contributions and earnings thereon. Upon termination of the Plan, all participants have equal priority in the distribution of any Plan assets in excess of Plan liabilities. Trustees and Administration The Company has entered into a trust agreement with Fidelity Management Trust Company (Fidelity) to handle duties as the named Trustee for the Plan. Three officers of the Company, Jerry V. Hoffman, Ralph J. Goehring and Kenneth A. Olson, are the Administrators of the Plan, and Berry Petroleum Company is the Plan Sponsor. The Administrators have the authority to delegate plan administration duties as necessary. Certain administrative expenses are paid by the Company. Fidelity, as the Trustee, receives contributions from the Plan Sponsor, invests and reinvests the Plan's assets, determines the market value of Plan assets, prepares statements and processes loans and withdrawals to beneficiaries. Note 2. Summary of Significant Accounting Policies Basis of Accounting The Plan's financial statements are prepared using the accrual method of accounting in accordance with generally accepted accounting principles. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of net assets available for benefits and changes therein. Actual results could differ from those estimates. 8

11 BERRY PETROLEUM COMPANY THRIFT PLAN NOTES TO FINANCIAL STATEMENTS Note 2. Summary of Significant Accounting Policies, continued Investments Quoted market prices as of the valuation date are used to compute the fair value of equity securities in the Berry Stock Fund and the 14 mutual funds. The value of the Managed Income Portfolio is based on the unit price quoted by the trust, representing the fair value of the underlying investments. In accordance with the policy of stating Plan assets at their fair value, the Plan presents the net appreciation (depreciation) in the fair value of its investments in the statement of changes in net assets, which consists of the realized gains or losses and the unrealized appreciation (depreciation) on those investments. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. Payment of Benefits Benefit payments to participants are recorded upon distribution. Expenses of the Plan The Plan's administrative expenses are paid by either the Plan or the Plan's Sponsor as provided by the Plan document. Note 3. Tax Status On June 7, 1988 the IRS advised the Company that the Plan meets the requirements of Section 401(a) of the Code, as restated by the Tax Reform Act of 1986, and is therefore exempt from federal income taxes under Section 501(a) of the Code. In 1994 conforming amendments, as requested by the IRS, were made to the Plan Agreement and a favorable determination letter was issued by them on December 7, 1994. The Plan has been amended and restated since the receipt of the prior IRS determination letter of December 7, 1994. The Plan Sponsor believes the Plan is designed to be, and is currently being operated, in compliance with the applicable requirements of the Internal Revenue Code (see Note 4 below). Note 4. Subsequent Events Fidelity received a favorable IRS Determination Letter from the IRS for their Prototype Plan (the Prototype Plan) in November 2002. The Sponsor had a choice of conforming the Plan to Fidelity's Prototype Plan so that they could rely on Fidelity's Determination Letter, or maintaining the Plan as is and filing their own determination letter for the differences that existed. After evaluation of the required changes and the benefits that would pass on to the participants, the Administrators elected to make the required changes to the Plan so that the Plan would conform to Fidelity's Prototype Plan. On March 6, 2003, the Board of Directors approved the adoption of Fidelity's Prototype 401(k) Plan along with the changes 9

12 BERRY PETROLEUM COMPANY THRIFT PLAN NOTES TO FINANCIAL STATEMENTS Note 4. Subsequent Events, continued required to conform Berry Petroleum Company's Plan to Fidelity's Prototype Plan. Future changes required to conform the Plan to IRS Regulations or rule changes will be implemented by Fidelity to their Prototype Plan, which has been adopted. The changes were implemented in two steps, the Prototype Plan was adopted and implemented in June 2003 and the Berry Petroleum Company Stock fund (Berry Stock Fund) is being changed from a share accounted fund option to a mutual fund accounted option effective July 1, 2003. After the switch to mutual fund accounting for the Berry Stock Fund, participants will be able to trade all of the investment options in the Plan on a daily basis, rather than daily for the mutual funds and the Managed Income Portfolio and only during the two monthly trading dates for Berry Stock (approximately on the 15th and 31st of each month.) This change will allow full internet access for Plan Participants, including investment transfers and loan and withdrawal requests without intervention by the Plan Administrators. Note 5. Transactions with Parties-in-Interest During the years ended December 31, 2002 and 2001, there were transactions involving investment of Plan assets in investment funds maintained by the Plan's trustee, a party-in-interest as defined in Section 3(14) of ERISA. One of the Plan's investment options is Berry Petroleum Company Common Stock which is purchased by the Plan's trustee in the open market. 10
