PART III—NARRATIVE

        State below in reasonable detail the reasons why Forms 10-K, 20-F, 11-K, 10-Q, N-SAR, N-CSR or the transition report or portion thereof, could not be filed within the prescribed time period.

1.

In the course of the Company's review of certain selected transactions and the associated account reconciliations at one of the Company's plants, an issue arose related to the substantiation of certain significant accounts related to the Company's year ended October 2, 2004. This substantiation was not completed by the Company until recently and is still subject to audit by our independent registered public accounting firm. Accordingly, the Company is unable to file its report on Form 10-K for the year ended October 2, 2004 on the due date. The Company expects that it will be in a position to file its Form 10-K for fiscal 2004 prior to December 31, 2004, the deadline for filing such report set forth pursuant to Securities and Exchange Commission Rule 12b-25.

2.

The Registrant hereby represents that the reasons causing the inability to timely file the annual report on Form 10-K could not be eliminated by the Registrant without unreasonable effort or expense.
