         of a Term Loan of either Class shall be applied to reduce ratably the

         previously paid, all Term Loans of each Class shall be due and payable

         notwithstanding, concurrently with any payment of Term Loans on March
         31, 2003, or any payment of Revolving Credit Loans or Incremental
         Revolving Credit Loans as a result of a reduction of Revolving Credit
         Commitments or Incremental Revolving Credit Commitments on March 31,

         a Vice President or a Financial Officer to the effect that on the date
         of such payments, and after giving effect thereto, no Default has
         occurred and is continuing (it being understood that the determination
         of whether or not a breach has occurred in respect of the financial
         covenants set forth in Section 7.09 shall be based upon the Borrower's
         good faith estimate of the financial results for the relevant fiscal
         periods ending on said March 31, 2003, which good faith estimate
         together with related computations of such covenants shall be set forth

         deposit the aggregate amount so received from the Borrower on such date
         into the Collateral Account (which amount shall be subject to
         application as provided in the Security Agreement)."

                  2.06.  Sections 2.10(a) and  2.10(b) of the Credit Agreement
are hereby amended in their entirety to read as follows:

                  "(a) Optional Prepayments. The Borrower shall have the right
                       --------------------
         at any time and from time to time to prepay any Borrowing in whole or
         in part, subject to the requirements of this Section, provided that (i)
                                                               --------
         the Borrower shall not prepay any Loans of any Class (other than a
         prepayment of Revolving Credit Loans concurrently with the issuance of
         a Letter of Credit in a face amount equal to such prepayment) unless it
         shall concurrently therewith prepay Loans of all Classes in such amount
         as shall be necessary so that the Lenders of each Class receive a
         prepayment in an amount equal to its Ratable Percentage of the
         aggregate prepayment of all Classes and (ii) each prepayment of Term
         Loans shall be applied ratably to the remaining scheduled installments
         thereof. In addition, on the sixth Business Day following any
         expiration or termination of a Letter of Credit (including pursuant to
         a drawing thereunder), unless and to the extent that within five
         Business Days following such expiration or termination the unused
         Revolving Credit Commitment that arises as a consequence thereof shall
         have been reutilized (whether through one or more Borrowings or the
         issuance of one or more Letters of Credit), the Borrower shall borrow
         Revolving Credit Loans and apply the proceeds thereof to the prepayment
         of Term Loans, and (whether or not the conditions precedent thereto set
         forth in Section 5.02 shall have been satisfied) the Revolving Credit
         Lenders shall make Revolving Credit Loans, in such amounts as shall be
         necessary so that the Lenders of each Class of Loans receive a
         reduction in Revolving Credit Exposure, or prepayment of Term Loans, in
         an amount equal to its Ratable Percentage of the aggregate reduction in

LC Exposure as a result of such expiration or termination (it being understood
that, during any time when an event referred to in clauses (h) or (i) of Article
VIII shall have occurred and be continuing, the Revolving Credit  Lenders may,
in lieu of such Borrowing and prepayment purchase participations or other
interests in the Loans of other Classes hereunder in a manner that achieves the
same economic effect of such Borrowing and prepayment).

     For purposes hereof, "Ratable Percentage" means, with respect to any Class
                           ------------------
of Lenders, the percentage equivalent of a fraction, the numerator of which is
the aggregate outstanding principal amount of the Loans held by the Lenders of
such Class (or, in the case of Revolving Credit Lenders or Incremental Revolving
Credit Lenders, the greater of the aggregate Revolving Credit Exposure or the
aggregate Incremental Revolving Credit Exposure, as the case may be, and the
aggregate amount of the Revolving Credit Commitments or the Incremental
Revolving Credit Commitments, as the case may be), and the denominator of which
is the sum of (i) the aggregate outstanding principal amount of the Term Loans
held by the Term Loan Lenders plus (ii) the greater of the aggregate Revolving
                              ----
Credit Exposure or the aggregate Incremental Revolving Credit Exposure, as the
case may be, and the aggregate amount of the Revolving Credit Commitments or the
Incremental Revolving Credit Commitments, as the case may be.

     (i)  Casualty Events.  Following the receipt by the Borrower of the
          ---------------
proceeds of insurance, condemnation award or other compensation in respect of
any Casualty Event affecting any property of the Borrower or any of its
Subsidiaries, the Borrower shall prepay the Loans (and/or provide cover for LC
Exposure as specified in Section 2.05(k)), and/or the Commitments shall be
subject to automatic reduction, in an aggregate amount, if any, equal to 100% of
the Net Available Proceeds of such Casualty Event to the extent required by the
next sentence of this clause (i), such prepayment and/or reduction to be
effected in each case in the manner and to the extent specified in clause (vi)
of this paragraph.

     Notwithstanding anything herein or in any Security Document to the
contrary, the Borrower shall be required to make a prepayment in respect of any
Casualty Event pursuant to this clause (i) as follows:

          (x)  The first $25,000,000 in the aggregate of Net Available Proceeds

     of Casualty Events may be used by the Borrower or any of its Subsidiaries
     to repair or replace the property affected by the relevant Casualty Event,
     provided that all such amounts in excess of $10,000,000 in the aggregate
     --------
     shall be deposited by the Borrower or the relevant Subsidiary into the
     relevant cash collateral account (in the case of property covered by the
     Security Agreement) or the Restoration Account (as defined in the relevant
     Mortgage) or similar account (in the case of property covered by a
     Mortgage) and shall be disbursed by the Administrative Agent (or mortgagee,
     as the case may be) upon request and certification by the Borrower that
     such amounts are to be used to repair or replace the property

                                                  -------- -------
     time the Borrower determines that it shall not repair or replace such
     property, the Borrower shall promptly notify the Administrative Agent
     thereof and, within 30 days thereof, prepay the Loans (and/or provide cover
     for LC Exposure) and/or the Commitments shall be reduced as provided in the
     first paragraph of this clause (i) in an amount equal to that portion of
     the Net Available Proceeds so determined not to be used for such repair or
     replacement (but in amounts not less than $1,000,000 and in $1,000,000
     increments); and

          (y)  All Net Available Proceeds of Casualty Events in excess of

     property affected by the relevant Casualty Event, within 30 days after the
     Borrower's receipt of such Net Available Proceeds, prepay the Loans (and/or
     provide cover for LC Exposure) and/or the Commitments shall be reduced as
     provided in the first paragraph of this clause (i) in an amount equal to
     such excess (but in amounts not less than $1,000,000 and in $1,000,000
     increments).

     Nothing in this paragraph shall be deemed to limit any obligation of the
Borrower or any of its Subsidiaries pursuant to any of the Security Documents to
remit to a collateral or similar account maintained by the Administrative Agent
pursuant to any of the Security Documents the proceeds of insurance,
condemnation award or other compensation received in respect of any Casualty
Event.

     (ii)  Debt Incurrence.  Upon any Debt Incurrence after the Effective Date,
           ---------------
the Borrower shall prepay the Loans (and/or provide cover for LC Exposure as
specified in Section 2.05(k)), and/or the Revolving Credit Commitments and/or

thereof, such prepayment and/or reduction to be effected in each case in the
manner and to the extent specified in clause (vi) of this paragraph.

     (iii)  Equity Issuance.  Upon any Equity Issuance after the Effective Date,
            ---------------

Credit Commitments and/or the Incremental Revolving Credit Commitments shall be
subject to automatic reduction, in an aggregate amount equal to 100% of Excess
Cash Flow for the two fiscal quarter period ending on such date, such prepayment
and/or reduction to be effected in

shall prepay the Loans (and/or provide cover for LC Exposure as specified in
Section 2.05(k)), and/or the Revolving Credit Commitments and/or the Incremental

collateral security and/or guarantees therefor, all of which are expressly

Documents, because each

Lender has bargained for and given valuable consideration for this Amendment
No. 5 and the other Credit Documents and its creation of express, explicit and
objective limits of what benefits each Lender is willing to provide to the
Borrower, and what, in return, the Borrower is required to provide to each
Lender. This Amendment No. 5 and the other Credit Documents provide a clear
statement of each Lender's requirements and obligations and creates an agreed

exercising and enforcing its respective remedies under the Credit Agreement and
the other Credit Documents.

Amendment No. 5, the Credit Agreement or any other Credit Document.

Agent nor any Lender intends to assume any such status at any time; and (iii)
neither the Administrative Agent nor any Lender shall be deemed responsible for
(or a participant in) any acts, omissions or decisions of the Obligors, or any
of their respective Affiliates, or any other Lender or, in the case of Lenders,

Party has been advised by counsel with respect to the release contained in this
Section 8. Each Releasing Party hereby affirms its intent to waive unknown
claims and to waive any statutory protection available in any applicable
jurisdiction with respect thereto.
