  Item 4.  Changes in Registrant's Certifying Accountant.
  
  Effective November 21, 2001, the Audit Committee and the Board of Directors of
  the Registrant approved a change in the Registrant's independent accountants for
  the fiscal year ending March 2, 2002 from KPMG LLP to Ernst & Young LLP ("Ernst
  & Young"). As a result, the Registrant informed KPMG LLP that, effective
  November 21, 2001, they had been dismissed as the Registrant's independent
  accountants. The report of KPMG LLP for the fiscal years ended March 3, 2001 and
  February 29, 2000, contained no adverse opinions, disclaimer of opinion or
  qualification or modification as to uncertainty, audit scope or accounting
  principles. During the fiscal years ended March 3, 2001 and February 29, 2000,
  and the interim period from March 4, 2001 through November 21, 2001, there were
  no disagreements between the Registrant and KPMG LLP on any matter of accounting
  principles or practices, financial statement disclosure or auditing scope or
  procedure, which, if not resolved to the satisfaction of KMPG LLP would have
  caused it to make reference to the subject matter of the disagreement in
  connection with its report. No event described in paragraph (a)(1)(v) of Item
  304 of Regulation S-K has occurred within the Registrant's fiscal years ending
  March 3, 2001 and February 29, 2000, or the interim period from March 4, 2001
  through November 21, 2001.
  
  The Registrant has provided KPMG LLP with a copy of the disclosures contained
  herein and has filed as an exhibit hereto the response of KPMG LLP to such
  disclosures.
  
  The Registrant did not consult with Ernst & Young during the fiscal years ended
  March 3, 2001 and February 29, 2000, and the interim period from March 4, 2001
  through November 21, 2001, on any matter which was the subject of any
  disagreement, as defined in paragraph 304(a)(1)(iv), or any reportable event, as
  described in paragraph 304(a)(1)(v), or on the application of accounting
  principles to a specified transaction, either completed or proposed.
