     mean, with respect to the revolving credit facility which replaces or
     refinances the Revolving Loan Agreement, an amount equal to the excess of
     (a) the lesser of (i) the total revolving commitment then in effect
     thereunder and (ii) the borrowing base, if any, then in effect, in each
     case after giving effect to reserves taken by the applicable agent under
     such replacement facility, over (b) an amount equal to the sum of (i) the

     modification or any such replacement is not satisfactory to the Required
     Lenders, such definition, for purposes of this Agreement, shall be subject
     to such adjustments as the Administrative Agent may reasonably require in
     order for the calculation of the Consolidated Fixed Charge Coverage Ratio
     to be as consistent as practicable with the calculation thereof prior to
     such amendment or other modification or such replacement); provided that on
     September 30, 2007 this amended definition shall cease to apply, and

     Third Amendment to the Term Loan Agreement, dated as of September 29, 2005.

          "Excess Cash Flow": for any fiscal quarter of the Borrower, the
     excess, if any, of (a) the sum, without duplication, of (i) Consolidated
     Net Income for such fiscal quarter, (ii) the amount of all non-cash charges

     Working Capital, (iv) to the extent not included in (ii) above, the cash
     impact of increases in post-petition employee benefits or post-petition

     increases in Consolidated Operating Working Capital, (iii) the aggregate
     amount actually paid or committed to be paid (such committed amounts to be

     (v) the cash impact of decreases in post-petition employee benefits or
     post-petition "Other Liabilities" (as reflected in the non-current section
     of Holdings' balance sheet), (vi) the aggregate net amount of non-cash gain
     on the Disposition of property by the Borrower and its Subsidiaries during
     such fiscal quarter (other than sales of inventory in the ordinary course
     of business), to the extent included in arriving at such Consolidated Net
     Income and (vii) the aggregate amount of loans and investments made during
     such fiscal quarter as contemplated by Sections 6.8(i) and (j).

          "Required Stated Amount": $7,500,000, provided that the Administrative
     Agent is by this proviso instructed, from time to time after the Fourth
     Amendment Effective Date, (a) to consent to an amendment to the Interest
     Reserve Letter of Credit (including any replacement Interest Reserve Letter
     of Credit) that provides for the Required Stated Amount (as it is reflected
     in the Interest Reserve Letter of Credit) to be promptly conformed to the
     relevant percentage of the then outstanding Tranche A Loans and Tranche B
     Loans as set forth below opposite the then most recent date set forth
     below, upon the issuer thereof receiving a notice from the Administrative
     Agent, to the effect that (i) all interest required to be paid on the Loans
     on or prior to the date of such notice has been paid and (ii) the Borrower
     has made all deposits required to be made on or prior to such date pursuant
     to Section 5.15, and (b) to provide the notice as contemplated in clause
     (a) above, upon a request by the Borrower to do so, so long as the
     statements in such notice are then true and correct.
