On June 14, 2002, the Company appointed Ernst & Young LLP as its independent accountants and terminated Arthur Andersen LLP as its independent accountants. The decision to change accountants was made because the accountants handling the Company's matters in the Oklahoma City office of Arthur Andersen LLP joined the Oklahoma City office of Ernst & Young LLP effective as of May 24, 2002. Arthur Andersen LLP has served as the independent accountants of the Company since 1999. The decision to change the Company's independent accountants was recommended by the Company's Audit Committee and approved by its Executive Committee, acting on behalf of the Board of Directors. In connection with the audits of the two fiscal years ended December 31, 2000, and 2001, respectively, there were no disagreements with Arthur Andersen LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements if not resolved to its satisfaction would have caused Arthur Andersen LLP to make reference to the subject matter of the disagreement in connection with its report. Additionally, during the two most recent fiscal years ended December 31, 2000 and 2001, respectively, there have been no reportable events (as defined in Regulation S-K, Item 304(a)(1)(v)). During the interim period subsequent to December 31, 2001, preceding the decision to change independent accountants, there were no disagreements with Arthur Andersen LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements if not resolved to its satisfaction would have caused Arthur Andersen LLP to make reference to the subject matter of the disagreement in connection with its report. Additionally, during the interim period subsequent to December 31, 2001, preceding the decision to change independent accountants, there have been no reportable events (as defined in Regulation S-K, Item 304(a)(1)(v)). The audit reports issued by Arthur Andersen LLP on the consolidated financial statements of the Company as of and for the years ended December 31, 2000 and 2001 did not contain an adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles.
