to permit the Replacement Transaction (as defined in Amendment No. 3).

          (3)  The Borrower has requested that the Lenders agree to an increase
in the aggregate principal amount of the Replacement Notes and to correct a
drafting error in Amendment No. 3.

Agreement as hereinafter set forth.

          sheet of such Person and its Subsidiaries (the "Employee Liability")
          for such period and (b) any decrease in pension asset that would be
          reflected on a consolidated balance sheet of such Person and its
          Subsidiaries (the "Pension Asset") for such period less (a) any
          decrease in the Employee Liability for such period and (b) any
          increase in the Pension Asset for such period.

          (b)  by amending the definition of "Indentures" in Section 1.1 in full
     to read as follows:

                    "Indentures" means, (a) until the issuance of the
          Replacement Notes, collectively, (i) the Permanent Financing Indenture

          the Replacement Notes, (i) the Replacement Indenture and (ii) the Term
          Loan Agreement, if any.

                    "Replacement Indenture" means the indenture incorporating
          terms and conditions no less favorable to Holdings than those terms
          and conditions set forth in Exhibit S hereto to be entered into to
          refinance the Permanent Financing Notes, between Holdings and the
          trustee thereunder, pursuant to which the Replacement Notes are
          issued, as the same may be amended, supplemented or modified from time
          to time; provided, however, that the aggregate principal amount of
          Replacement Notes that may be issued
<PAGE>   3
                                       3

     pursuant to the Replacement Indenture and the Term Loan Agreement shall not
     exceed in the aggregate $450,000,000.

     (d) by amending the definition of "Replacement Notes" in Section 1.1 in
full to read as follows:

          "Replacement Notes" means Holdings market rate senior notes, whether
     fixed rate or floating, issued in one or more series, with a term of not

     (e) by adding the following definition to Section 1.1:

          "Term Loan Agreement" means the term loan agreement, if any,
     incorporating terms and conditions no less favorable to Holdings than those
     terms and conditions set forth in Exhibit S hereto (other than a floating
     interest rate and an optional call provision one year from issuance) to be
     entered into to refinance the Permanent Financing Notes, between Holdings
     and the purchasers under the foregoing term loan agreement, pursuant to
     which the Replacement Notes are issued, as the same may be amended,
     supplemented or otherwise modified from time to time; provided, however,
     that the aggregate principal amount of Replacement Notes that may be issued
     pursuant to the Replacement Indenture and the Term Loan Agreement shall not
     exceed in the aggregate $450,000,000.

     (f) by amending Section 4.11 in full to read as follows:

          4.11. Replacement Notes. Neither the Replacement Indenture nor the
     Term Loan Agreement has been amended or modified since its effective date

          (except a non-payment default on any of the Replacement Notes, the
          effect of which is not to accelerate or permit the acceleration of the
          maturity of any of the Replacement Notes)

          SECTION 3.  Conditions of Effectiveness. This Amendment shall become
