                    (a) Maximum Capital Expenditures. Borrower and its

               consolidated basis shall not make aggregate Capital Expenditures

                                       2



Fiscal Year Ending On                            Maximum Capital Expenditures
- ---------------------                            ----------------------------
                                              
July 1, 2005                                     $275,000,000
June 30, 2006                                    $280,000,000
June 29, 2007, and each Fiscal Year thereafter   $290,000,000


               provided; that, to the extent that the maximum capital
               expenditure amount identified above (the "Maximum Capital
               Expenditure") for any such Fiscal Year (i.e., Year 1) exceeds the
               amount of Capital Expenditures actually made by Borrower and such
               Subsidiaries during such Fiscal Year (such excess being the
               "Excess Amount"), then the amount of permitted Capital
               Expenditures for the immediately succeeding Fiscal Year (i.e.,
               Year 2) will be increased by the positive amount (the "Carry Over
               Amount") equal to the lesser of (i) the Excess Amount and (ii)
               25% of the amount of the Maximum Capital Expenditure for such
               Fiscal Year (i.e., Year 1), and for purposes of measuring
               compliance herewith, the Carry Over Amount shall be deemed to be
               the last amount spent on Capital Expenditures in any Fiscal Year.

               (e) The following is hereby added as paragraph (c) of Annex G to
     the Credit Agreement:

                    (c) Borrower and its Subsidiaries (other than the Excluded
               Subsidiaries) on a consolidated basis shall not make aggregate
               Capital Expenditures in any Fiscal Year that exceed the total
               EBITDA for Borrower and its Subsidiaries (other than the Excluded
               Subsidiaries) on a consolidated basis for such Fiscal Year.
