CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT. On July 30, 2002, we dismissed our independent auditor Arthur Andersen LLP ("Andersen"), and engaged KPMG LLP ("KPMG") as our new independent auditor for our current fiscal year ending December 31, 2002. Our Audit Committee recommended the change of auditor, and our Board of Directors approved the change. During our two most recent fiscal years ended December 31, 2001, and the subsequent interim period through July 30, 2002, there were: (1) no disagreements between us and Andersen on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to Andersen's satisfaction, would have caused Andersen to make reference to the subject matter of the disagreement in connection with its reports, and (2) no reportable events described under Item 304 (a) (1) (v) of Regulation S-K. The audit reports of Andersen on our consolidated financial statements as of and for the fiscal years ended December 31, 2000 and 2001 did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles. We have provided Andersen with a copy of the foregoing disclosures. After reasonable efforts, we have been unable to obtain the letter from Andersen that is required by Item 304(a)(3) of Regulation S-K. We have therefore not included such letter as an exhibit to this Current Report on Form 8-K pursuant to Item 304T(b)(2) of Regulation S-K. During our two most recent fiscal years ended December 31, 2001, and the subsequent interim period through July 30, 2002, we did not consult with KPMG regarding any of the matters or events set forth in Item 304 (a) (2) (i) and (ii) of Regulation S-K. Pursuant to the requirements of the Securities Exchange Act of 1934, the Registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
