</FONT>

<FONT SIZE=2><P>The Company's Annual Report on Form 10-K for the fiscal year ended May 28, 2005 cannot be filed within the prescribed time period because of delays associated with the completion of the audit.  The Company is still responding to requests from its independent auditors for supporting documentation primarily related to accounting for income taxes and, as a result, the Company's auditors are unable to complete the financial audit of the Company's financial statements by the required filing date of August 11, 2005.  As a result of the delay in the completion of the financial audit, the Company is unable to complete its assessment of internal controls over financial reporting by the required filing date of August 11, 2005, as well.<br />
&nbsp;<br />
The Company anticipates filing its Annual Report on Form 10-K for the year ended May 28, 2005 within the regulatory fifteen-day extension period. <br />
