2 BERRY PETROLEUM COMPANY FORM 10-K/A Amendment No. 1 Explanatory Note On March 12, 2003, the Registrant filed its Form 10-K on Edgar with the Securities and Exchange Commission. This Form 10- K inadvertently contained errors in the first sentence for the wording used for the Opinion Page for the Independent Accountants. The correct wording for the Report of PricewaterhouseCoopers LLP, Independent Accountants is included in this Form 10-K/A. The Form 10-K filed also contained an incorrect reference in the Section 302 Certifications from the CEO and CFO under number 2 to a quarterly rather than an annual report. Those certifications are enclosed herewith with the correction made in this Form 10-K/A. All other information contained in our original Form 10-K filing remains unchanged.

3 REPORT OF INDEPENDENT ACCOUNTANTS To the Shareholders and Board of Directors Berry Petroleum Company In our opinion, the accompanying balance sheets and the related statements of income, comprehensive income, shareholders' equity and cash flows present fairly, in all material respects, the financial position of Berry Petroleum Company at December 31, 2002 and 2001, and the results of its operations and its cash flows for each of the three years in the period 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 Company'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. /s/ PricewaterhouseCoopers LLP February 12, 2003
