ITEM 4. Changes in Registrant's Certifying Accountant On June 18, 2004, Deloitte notified the Company of its intent to resign as the Company's independent registered public accounting firm effective immediately upon the completion of Deloitte's review of the Company's unaudited condensed consolidated interim financial statements to be included in the Company's Form 10-Q for the quarter ended July 3, 2004. Deloitte completed its review on August 23, 2004 and Deloitte's resignation became effective as of that date. The decision to change accountants was not recommended or approved by the audit committee of the Company's board of directors.

During fiscal 2002 and 2003 and the subsequent period through August 23, 2004, there were no disagreements between the Company and Deloitte on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure which disagreements, if not resolved to Deloitte's satisfaction, would have caused Deloitte to make reference thereto in Deloitte's reports on the Company's financial statements for such periods. In addition, no reportable events, as defined in Item 304(a)(1)(v) of Regulation S-K, occurred during the Company's two most recent fiscal years, 2002 and 2003, and through August 23, 2004. The Company has requested that Deloitte furnish it with a letter addressed to the Securities and Exchange Commission stating that it agrees with the above statements.
