 EXPLANATORY NOTE We are filing this Amendment No. 1 to the Companys Quarterly Report on Form
10-Q for the quarter ended September 25, 2004 solely to amend Part 1, Item 4.
of the Quarterly Report of Form 10-Q as originally filed on November 9, 2004.
This Amendment does not reflect any events occurring after the original date of
filing of the report on Form 10-Q, or otherwise modify or update any of the
information contained therein. 
 Item 4.      Controls and Procedures Evaluation of Disclosure Controls and Procedures The Companys President, Chief Executive Officer, and Chairman of the Board, O.
Victor Edelbrock, and the Companys Vice-President of Finance and Chief
Financial Officer, Aristedes T. Feles, evaluated the Companys disclosure
controls and procedures as of September 25, 2004. These controls and procedures
are designed to ensure that all of the information required to be disclosed by
the Company in its periodic reports filed with the Securities and Exchange
Commission (the Commission) is recorded, processed, summarized and reported
within the time periods specified in the rules and forms of the Commission and
that the information is accumulated and communicated to the Companys
management, including Messrs. Edelbrock and Feles on a timely basis. As required by Rule 15d-15, promulgated by the Commission under the
Securities Exchange Act of 1934, as amended (the Exchange Act), the Company
carried out an evaluation, under the supervision and with the participation of
management, including the Companys Chief Executive Officer and Chief Financial
Officer, of the effectiveness of the design and operation of the Companys
disclosure controls and procedures as of the end of the fiscal quarter ended
September 25, 2004 covered by this report. Based on the foregoing, the
Companys Chief Executive Officer and Chief Financial Officer concluded that
the Companys disclosure controls and procedures are effective to provide
reasonable assurance that information required to be disclosed in the reports
that the Companys files or submits under the Exchange Act is recorded,
processed, summarized, and reported within the time periods specified in the
Commissions rules and forms. Subsequent to the date of such evaluation, there
has been no change in the Companys internal controls over financial reporting
that occurred during the period covered by this report that has materially
affected, or are reasonably likely to materially affect, the Companys internal
controls over financial reporting. 2
