CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT On April 16, 2003, Deloitte & Touche LLP ("Deloitte") notified Registrant that it did not intend to stand for reelection as Registrant's principal independent accountant. The reports of Deloitte on Registrant's financial statements for the fiscal years ended December 31, 2001 and 2000 have not included an adverse opinion or a disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principles. However, as previously announced by Registrant, the Audit Committee is currently conducting an investigation into issues involving revenue recognition, which, upon completion of this investigation, may materially impact the previously issued financial statements and related reports. During the fiscal years ended December 31, 2001 and 2000 and the period from January 1, 2002 to April 16, 2003, (a) there were no disagreements with Deloitte on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Deloitte, would have caused Deloitte to make reference to the subject matter of the disagreements in connection with its report, and (b) there were no "reportable events" as the term is defined in Item 304(a)(1)(v) of Regulation S-K. However, as previously announced by Registrant, the Audit Committee is currently conducting an investigation into issues involving revenue recognition, which, upon completion of this investigation, may result in a determination that events requiring additional disclosure under Item 304(a)(1)(v) of Regulation S-K have occurred. Registrant has furnished Deloitte with a copy of the foregoing disclosures and has requested Deloitte to furnish Registrant with a letter addressed to the Securities and Exchange Commission stating whether it agrees with the above statements and, if not, stating the respects in which it does not agree.
