TRANSLATION REPORT OF INDEPENDENT AUDITOR To the shareholders of The Bangchak Petroleum Public Company Limited The State Audit Office has reviewed the balance sheets as at as at March 31,2001 and 2000, the statements of income , the statements of changes in shareholders' equity and the statements of cash flows for the three months then ended of The Bangchak Petroleum Public Company Limited. These financial statements are the responsibility of the Company's management as to their fair presentation and completeness of the information. The responsibility of the State Audit Office is to report on these financial statements based on the results of its review. The State Audit Office conducted the review in accordance with the auditing standards applicable to review engagements. Those standards require that the State Audit Office plans and performs the review to obtain moderate assurance as to whether the financial statements are free of material misstatement. A review is limited primarily to inquiries of the company personnel and analytical comparison of financial data. This, therefore, provides less assurance than an audit in accordance with the generally accepted auditing standards. Due to this , the State Audit Office is unable to express an opinion on the financial statements referred to above. Based on our review, nothing has come to attention that causes the State Audit Office to believe that the financial statements are not presented fairly , in all material respects , in conformity with the generally accepted accounting principles. The State Audit Office audited the financial statements as at December 31,2000 of The Bangchak Petroleum Public Company Limited in accordance with the generally accepted auditing standards and expressed an unqualification opinion as per the independent auditor report dated February 23, 2001. The balance sheets as at December 31,2000 as presented herein for comparison, formed partly the financial statements which the State Audit Office previously audited and reported. The State Audit Office has not performed any other audits since the date of that report .
