Croatti -------------------------------------- Ronald D. Croatti President and Chief Executive Officer Date: July 7, 2005 By: /s/ John B. Bartlett -------------------------------------- John B. Bartlett Senior Vice President and Chief Financial Officer 2 ATTACHMENT A In response to certain comments provided by the Securities and Exchange Commission to the Company, including in its most recent correspondence on June 30, 2005, the Company will include additional segment reporting in its Form 10-Q and 10-K filings, commencing with the Company's 10-Q filing for the quarter ended May 28, 2005 (in addition to revising applicable disclosures in the Company's Form 10-K for its fiscal year ended August 28, 2004). The Company has been working to prepare its Form 10-Q to include segment reporting. However, because the Company has not prepared its filings utilizing these reporting segments in previous filing periods, the Company's current preparation of the Form 10-Q for the quarter ended May 28, 2005 is taking additional time and management attention. As a result, the Company is unable, without unreasonable effort and expense, to complete and file the Form 10-Q by July 7, 2005, the prescribed deadline for filing. The Company intends to file the Form 10-Q within 5 calendar days of the prescribed due date for the Form 10-Q, or July 12, 2005. 3
