Change In Independent Accountants Effective May 27, 1998, the Registrant terminated Ernst & Young LLP as its independent accounting firm. The termination of Ernst & Young LLP was approved by the Audit Committee of the Board of Directors of the Registrant. Ernst & Young LLP's report on the financial statements of the Registrant for each of the last two fiscal years neither contained an adverse opinion or a disclaimer of opinion, nor was qualified or modified as to uncertainty, audit scope, or accounting principles. During the Registrant's two most recent fiscal years and the interim period through May 27, 1998, there were no disagreements or "reportable events" with Ernst & Young LLP as described in Items 304(a)(1)(iv) and (v) of Regulation S-K. Accordingly, Ernst & Young LLP has not advised the Registrant of (i) the absence of the internal controls necessary for the Registrant to develop reliable financial statements, (ii) any information which would cause Ernst & Young LLP to no longer rely on management's representations, or that Ernst & Young LLP was unwilling to be associated with the financial statements prepared by management, (iii) any need to expand significantly the scope of its audit, or any information that if further investigated may (a) materially impact the fairness or reliability of either a previously issued audit report or the underlying financial statements or any financial statements for any fiscal period subsequent to the date of the most recent financial statements covered by an audit report or (b) cause it to be unwilling to rely on management's representations or be associated with the Registrant's financial statements, or (iv) any information that has come to the attention of Ernst & Young LLP that it concluded materially impacts the fairness or reliability of either (a) a previously issued audit report or the underlying financial statements or (b) any financial statements issued or to be issued covering any fiscal period subsequent to the date of the most recent financial statements covered by an audit report. Effective June 3, 1998, the Registrant engaged Deloitte & Touche LLP as its independent accounting firm. Neither the Registrant or any of its subsidiaries has had any prior relationships with Deloitte & Touche LLP.
