You may revoke your proxy at any time prior to its exercise by giving written notice to the Secretary of the Company.

Unless otherwise directed in the accompanying Proxy, persons named therein will vote FOR the election of the ten director nominees listed below. As to any other business that may properly come before the Meeting, the proxy holders will vote in accordance with the recommendation of the Board of Directors. VOTING SECURITIES March 12, 2003 has been fixed as the record date for determination of shareholders entitled to notice of, and to vote at, the Annual Meeting or any adjournment thereof. As of February 14, 2003 there were 20,860,070 and 898,892 shares, respectively, of Class A Common Stock (Common Stock) and Class B Stock (Class B Stock), par value $.01 per share, issued and outstanding, referred to collectively as the Capital Stock. Berry's Certificate of Incorporation provides that, except for proposed amendments to Berry's Certificate of Incorporation adversely affecting the rights of a particular class (which must be approved by the affected class voting separately), the Common Stock and the Class B Stock will vote as a single class on all matters upon which the Capital Stock is entitled to vote. Each share of Common Stock is entitled to one vote and each share of Class B Stock is entitled to 95% of one vote. The Certificate of Incorporation also provides for certain adjustments to the Capital Stock in the event a separate class vote is imposed by applicable law. Holders of the Capital Stock are entitled to cumulative voting rights for election of directors. Cumulative voting rights entitle a shareholder to cast as many votes as is equal to the number of directors to be elected multiplied by the number of shares owned by such shareholder. A shareholder may cast all of such shareholder's votes as calculated above for one candidate or may distribute the votes among two or more candidates. Unless otherwise instructed, the shares represented by proxies will be voted in the discretion of the proxy holders so as to elect the maximum number of management nominees which may be elected by cumulative voting. 1

Salary continuation agreements for certain other executives provide for the payment of six months' salary upon a termination of employment in connection with a Change of Control. The Company entered into an agreement with Mr. Duginski, at his date of hire, whereby he is guaranteed a 12 month notice of termination or his base salary will continue for a period of 12 months, should his services be terminated by the Company prior to February 1, 2004. 9

Life Insurance Coverage The Company provides certain individuals who are officers or other high-level executives with life insurance coverage in addition to that available to employees under the Company's group-term life insurance plan. The amount of this life insurance coverage is $500,000 for Mr. Hoffman, $500,000 for Mr. Goehring, $412,500 for Mr. Rehkopf, $375,000 for Mr. Crawford and $437,500 for Mr. Duginski. Depending on certain variables, an executive or beneficiary may be entitled to insurance benefits exceeding the amount of term insurance that could otherwise have been purchased with the portion of the premium payments that are imputed to the executive as taxable income. The Company has had policies of this type and in these relative amounts in place for certain executives for over 20 years. Notwithstanding anything to the contrary set forth in any of the Company's previous filings under the Securities Act of 1933, as amended, or the Exchange Act that might incorporate future filings, including this Proxy Statement, in whole or in part, the following report of the Audit Committee, the report of the Compensation Committee and the performance graph shall not be incorporated by reference into any such filings. Audit Committee Report To the Board of Directors The Audit Committee consists of the following members of the Board of Directors: Martin H. Young, Jr. (Chairman), Stephen L. Cropper, J. Herbert Gaul, Jr., and Thomas J. Jamieson. Mr. Martin was a member of the Audit Committee for all of 2002, prior to his retirement on January 2, 2003. Each of the members is independent as defined under the rules of the New York Stock Exchange. We have reviewed and discussed with management the Company's audited financial statements as of, and for the year ended December 31, 2002. We have discussed with the independent auditors, PricewaterhouseCoopers LLP (PWC), the matters required to be discussed by Statement on Auditing Standards No. 61, Communication with Audit Committees, as amended, by the Auditing Standards Board of the American Institute of Certified Public Accountants. We have received and reviewed the written disclosures and the letter from PWC required by Independence Standard No. 1, Independence Discussions with Audit Committees, as amended, by the Independence Standards Board, and have discussed with the auditors the auditors' independence. The Audit Committee has reviewed the services provided by the independent auditors and has specifically pre-approved the provision of tax and hedge accounting services by the auditor and determined that all fees billed by PWC for non-audit services are compatible with maintaining the auditor's independence. Based on the reviews and discussions referred to above, we recommend to the Board of Directors that the financial statements referred to above be included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2002 for filing with the Securities and Exchange Commission. Audit Committee of the Board of Directors March 1, 2003 Martin H. Young, Jr. (Chairman), Stephen L. Cropper, J. Herbert Gaul, Jr. Thomas J. Jamieson 10

Auditor Independence Report In conjunction with recent SEC releases on auditor independence, the following items are disclosed herein: Audit Fees For the audit for the year ended December 31, 2002, the Company was billed $188,760 by PWC, its principal accountant, for the audit and quarterly reviews completed. Financial Information Systems Design and Implementation Fees No fees were billed for Financial Information Systems Design and Implementation. All Other Fees The Company was billed $39,190 for all other non-audit services provided by PWC, its principal accountant and by Qbyte, an affiliate of PWC for the year ended December 31, 2002. Qbyte was sold in October 2002 and is no longer affiliated with PWC. PWC has represented to the Company that none of the work performed for the Company was by persons other than PWC's full-time permanent employees and that such employees were independent from the Company. Board Compensation Committee Report on Executive Compensation The Company's executive compensation program is administered by the Compensation Committee of the Board of Directors. Currently, the Committee is composed of three non-employee directors, however, prior to Mr. Martin's retirement in January 2003, the Committee was composed of four non-employee directors for all of 2002. The Committee is committed to a strong, positive link between business performance and the attainment of strategic goals and the overall compensation and benefit programs. Report of Compensation Committee on Executive Compensation Policy The Company's compensation policy is designed to support the overall objective of maximizing the return to Berry's shareholders by: - - Attracting, developing, rewarding, and retaining highly qualified and productive individuals. - - Directly aligning compensation to both Company and individual performance. - - Ensuring compensation levels that are externally competitive and internally equitable. - - Encouraging executive stock ownership to enhance a mutuality of interest with the Company's shareholders. The following is a description of the elements of executive compensation and how each relates to the objectives and policy outlined above. Base Salary The Committee reviews each executive officer and certain other management employees' salaries annually. In determining appropriate salary levels, we consider the level and scope of responsibility, experience, Company and individual performance, internal equity, as well as pay practices of other companies relating to executives of similar responsibility. By design, we strive to set executives' salaries at competitive market levels. 11

Short-Term Incentive Plan Compensation The Short-Term Incentive Plan (Bonus Plan) awards cash bonuses to executives and other employees to recognize and reward Company and individual performance. Subject to the Board's discretion to vary the targets, the Bonus Plan was restructured in early 2001 to focus on three specific Company targets, these being: production volume, reserve replacement and non-steam operating costs. Based on the Company's net income, the Bonus Plan provides an annual incentive fund for eligible employees involved in decision-making roles which effect the Company's business performance and the attainment of established strategic goals. Bonuses may also be awarded for discretionary performance by the Chief Executive Officer for other employees whose efforts and performance are judged to be exceptional. The Company anticipates that future annual bonuses, if any, will be determined in December of each year. Cash bonuses paid in 2002, 2001 and 2000 were $669,000, $1,033,000 and $465,000, respectively. Cash bonuses of $465,000 were declared in December 2002 and paid in January 2003 for 2002 performance. The amount an individual may earn is directly dependent upon the individual's position, responsibility, and ability to impact the Company's financial success. External market data is reviewed periodically to determine the competitiveness of the Company's incentive programs for eligible individuals. Long-Term Incentive Plan Compensation Non-Statutory Stock Option Plan (Stock Option Plan) The purpose of this plan is to provide additional incentives to employees to stay focused on the long-term goal of maximizing shareholder value and to encourage management to own and hold the Company's stock and tie their long-term economic interests directly to those of the Company's shareholders. While the Compensation Committee maintains substantial flexibility in the operation of the Stock Option Plan, it was restructured in early 2001 to consider the link of the quantity of options allowable for grant with the Company's stock performance measured in comparison to a select peer group of other U.S. based exploration and production companies. The Stock Option Plan utilizes vesting periods to encourage key employees to continue in the employ of the Company and grants options which have an exercise price at market value on the date of grant. The Compensation Committee is charged with responsibility for administering and granting non-statutory stock options. At December 31, 2002, an aggregate of 1,007,100 options are available for issuance from the 1994 Stock Option Plan. Options granted in 2002, 2001 and 2000 to employees were 191,200, 199,500 and 262,000, respectively. Chief Executive Officer The Committee believes Mr. Hoffman has done a good job of leading and managing the Company during a volatile and rapidly-changing period for the energy industry as witnessed over the last several years and has restored the Company's oil production to its pre-California electricity crisis levels. Additionally, Mr. Hoffman was successful in recruiting talented individuals in 2002 to assist the Company in meeting its strategic goals and being positioned favorably for continued growth. Mr. Hoffman, as Chief Executive Officer, has also demonstrated a keen ability in redirecting the Company's resources to higher profitability projects and growth opportunities. Mr. Hoffman's compensation incentives are primarily derived from the Bonus Plan and the Stock Option Plan. The ultimate value of the stock options received are directly related to the Company's current and future stock performance. Compensation Committee of the Board of Directors March 1, 2003 Thomas J.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS Eagle Creek Mining & Drilling, Inc. Eagle Creek Mining & Drilling, Inc. (Eagle Creek), a California corporation, was a wholly-owned subsidiary of the Company's predecessor, Berry Holding Company, until it was spun off to the majority shareholders of the predecessor in 1984. On November 30, 1989, Eagle Creek purchased the assets of S&D Supply Company (S&D), a California partnership. S&D, a retail distributor of oilfield parts and supplies, is now a division of Eagle Creek. The five-year contract whereby the Company purchased oilfield parts and supplies from S&D at competitive prices expired November 30, 1999 and was not renewed. Even though the contract expired, based on competitive pricing, the Company continues to purchase oilfield parts and supplies from S&D. The amounts paid to S&D in 2002, 2001 and 2000 were $396,067, $332,000 and $713,000, respectively. Mr. Ralph B. Busch, III and his immediate family are significant beneficial owners of the stock of Eagle Creek. Halliburton Energy Services During 2002, the Company paid Halliburton Energy Services $1,418,578 for services and equipment provided by Halliburton to the Company. The Company has used Halliburton's services for in excess of 10 years and anticipates using Halliburton's services in the future, including in 2003. All contracts awarded to Halliburton are based on competitive bid circumstances unless a particular service is in management's judgement best provided by Halliburton due to its experience, expertise or availability considering all circumstances. Mr. Heinemann served as Senior Vice President and Chief Technology Officer of Halliburton Company from 2000 until his resignation in December 2002. The compensation paid by Halliburton to him and the compensation paid to him as a director of the Company were not affected by any payments from Berry Petroleum Company to Halliburton or its affiliates or subsidiaries. Tristone Capital Advisors During 2002, the Company paid Tristone Capital Advisors (Tristone) $134,325 under the terms of a letter agreement dated January 21, 2002 (the Agreement). Under the Agreement, Tristone received a consulting fee of $25,000 monthly for services rendered between January 21, 2002 and June 30, 2002 by Tristone for providing the Company assistance in evaluation of potential acquisitions in Canada. In addition, Tristone was to receive a "success fee" of ..625% to 1.2% of the "Enterprise Value" of the transaction should the Company complete an acquisition covered by the Agreement and for a period of nine months following the contract termination. No such success fee was paid or is payable under the Agreement. The Agreement expired on June 30, 2002 and was not renewed. Mr. John A. Hagg, a director of Berry Petroleum Company, became a shareholder and director of Tristone in February 2002. Victory Settlement Trust In connection with the reorganization of the Company in 1985, a shareholder of Berry Holding Company (BHC), Victory Oil Company (Victory), a California partnership, brought suit against Berry Holding Company (one of Berry's predecessor companies prior to the reorganization in 1985) and all of its directors and officers and certain significant shareholders seeking to enjoin the reorganization. As a result of the reorganization, Victory's shares of BHC stock were converted into shares of Berry Common Stock representing approximately 9.7% of the shares of Berry Common Stock outstanding immediately subsequent to the reorganization. In 1986, Berry and Victory, together with certain of its affiliates, entered into the Instrument for Settlement of Claims and Mutual Release (the Settlement Agreement). The Settlement Agreement provided for the exchange (and retirement) of all shares of Common Stock of Berry held by Victory and certain of its affiliates for certain assets (the Settlement Assets) conveyed by Berry to Victory. The Settlement Assets consisted of (i) a 5% overriding royalty interest in the production removed or sold from certain real property situated in the Midway-Sunset field which is referred to as the Maxwell property (Maxwell Royalty) and (ii) a parcel of real property in Napa, California. 14

Victory Settlement Trust (Cont'd) The shares of BHC originally acquired by Victory and the shares of Berry Common Stock issued to Victory in exchange for the BHC Stock in the reorganization (the Victory Shares) were acquired subject to a legend provision designed to carry out certain provisions of the Will of Clarence J. Berry, the founder of Berry's predecessor companies. The legend enforces an Equitable Charge (the Equitable Charge) which requires that 37.5% of the dividends declared and paid on such shares from time to time be distributed to a group of lifetime income beneficiaries (the B Group). As a result of the Settlement Agreement, the B Group was deprived of the distributions related to the stock that they would have received on the Victory Shares under the Equitable Charge. In order to adequately protect the interests of the B Group, Berry executed a Declaration of Trust (the Victory Settlement Trust). In recognition of the obligations of Berry and Victory with respect to the Equitable Charge, Victory agreed in the Settlement Agreement to pay to Berry in its capacity as trustee under the Victory Settlement Trust, 20% of the 5% Maxwell Royalty (Maxwell B Group Payments). The Maxwell B Group Payments will continue until the death of the last surviving member of the B Group, at which time the payments will cease and the Victory Settlement Trust will terminate. There is one surviving member of the B Group. Under the Settlement Agreement, Berry agreed to guarantee that the B Group will receive the same distributions under the Equitable Charge that they would have received had the Victory shares remained as issued and outstanding shares. Accordingly, when Berry declares and pays dividends on its capital stock, it is obligated to calculate separately the applicable distribution (the Trust Payment). Berry will make payments from the Victory Settlement Trust to the surviving member of the B Group, which payments may constitute all or a part of the Trust Payment in March and September of each year. Such payments will be made to the surviving member of the B Group for the remainder of his life. Typically, the Maxwell B Group Payments have contributed to a portion or all of the Trust Payment. Pursuant to the Settlement Agreement, Berry paid $ 115,675 to the Victory Settlement Trust in 2002. Wholesale Fuels Inc. The Company bid out its lubrication business in 2001 to various vendors. The bid was awarded to Wholesale Fuels Inc., as it was the low bidder, for a period of two years beginning July 15, 2001 and ending July 15, 2003. The Company paid $72,409 to Wholesale Fuels Inc. in 2002 under the terms of the bid. Mr. Thomas J. Jamieson, a director of Berry Petroleum Company, is the majority owner and founder of Wholesale Fuels Inc. 15
