                  Collateral, 2.50 to 1.00 and (ii) otherwise, 3.00 to 1.00. For
                  purposes of this section, EBITDA shall exclude the $34,400,000
                  restructuring charge recorded in the fiscal quarter ending
                  June 28, 1999.

         (J)      SECTION 10.3 is entirely amended as follows:

                  the last day of each fiscal quarter (commencing June 25, 2000)
                  of Borrower for the four quarters then ended of (a) the
                  DIFFERENCE of the Companies' EBITDA MINUS Capital Expenditures
                  TO (b) Interest Expense to be LESS THAN 3.50 to 1.00. For
                  purposes of calculating the Companies' Capital Expenditures
                  and Interest Expense for any four-quarter period, the
                  Companies' Capital Expenditures and Interest Expense for that
                  period shall, to the extent reflected in Financials acceptable
                  to Agent, include the Capital Expenditures and Interest of any
                  Person that became a Subsidiary of Borrower or was merged with
                  or consolidated into Borrower during that period as if it had
                  been acquired, merged, or consolidated at the beginning of
                  that period.

         (K)      A new SECTION 10.4 is added as follows:

                           10.4 CONSOLIDATED EBITDA. The Companies' EBITDA to be
                  LESS THAN (a) for the fiscal quarter ending October 3, 1999,
                  $11,500,000, (b) for the six-month period ending January 2,
                  2000, $24,000,000, and (c) for the nine-month period ending
                  March 26, 2000, $41,000,000.

         (L)      SCHEDULE 2.1 and EXHIBIT B-4 are amended in the forms of, and
all references in the Loan Documents to that schedule and exhibit are changed
to, the attached SECOND AMENDED SCHEDULE 2.1 and AMENDED EXHIBIT B-4,
