<PAGE>
         "Holdings Notes": the Original Holdings Notes or any Refinancing
         Holdings Notes.

         Replacement Tranche B Effective Date in one or more series from time to
         time pursuant to one or more Holdings Note Indentures, provided that
         (a) each series of such notes shall (i)(x) be issued at a discount and
         not require the payment of interest in cash thereon prior to the fifth
         anniversary of the Replacement Tranche B Effective Date or (y) permit
         the payment of any interest thereon prior to such fifth anniversary in
         kind (it being understood that a "catch-up" payment in an amount
         sufficient to avoid such notes having significant original issue
         discount as described in Section 163(i)(2) of the Code, may be required
         to be made in or after the year following such fifth anniversary), (ii)
         be issued in a maximum aggregate amount such that the aggregate
         principal amount thereof that would appear on a balance sheet of
         Holdings as of the date of such issuance, prepared in accordance with
         GAAP, shall not exceed the amount which would cause the Consolidated

         notes to exceed 5.50 to 1, (iii) not have a scheduled maturity or
         provide for any scheduled payments of principal thereon prior to the

         shall (a)(i) be issued at a discount and not require the payment of
         interest in cash thereon prior to the fifth anniversary of the
         Replacement Tranche B Effective or (ii) permit the payment of any
         interest thereon prior to such fifth anniversary in kind (it being
         understood that a "catch-up" payment in an amount sufficient to avoid
         such notes having significant original issue discount as described in
         Section 163(i)(2) of the Code, may be required to be made in or after
         the year following such fifth anniversary), (b) be issued in a maximum
         aggregate principal amount such that the Net Cash Proceeds thereof do
         not exceed the then aggregate principal amount (or then accreted value)

         Original Holdings Notes or the Refinancing Holdings Notes refinanced
         thereby, (c) not have a scheduled maturity or provide for any scheduled
         payments of principal thereon prior to the date six months after the

         reasonably acceptable to the Administrative Agent. Any Refinancing
         Holdings Notes shall include any accretion in the principal amount
         thereof and any pay-in-kind notes issued for the payment of interest
         thereon pursuant to the relevant Holdings Note Indenture. The
         Refinancing Holdings Notes may take the form of Disqualified Capital
         Stock and, in such event, references above to payments of interest
         shall be deemed to refer to required or regularly scheduled dividend
         payments, references to notes shall be deemed to refer to capital
         stock, references to scheduled maturity and scheduled payments of
         principal shall be deemed to refer to scheduled mandatory redemption

bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or
similar laws affecting creditors' rights generally, by general equitable
principles (whether enforcement is sought by proceedings in equity or at law)
and an implied covenant of good faith and fair dealing; (ii) the representations
and warranties made by the Loan Parties in the Loan Documents are true and
correct in all material respects on and as of the date hereof (except to the
extent that such representations and warranties are expressly stated to relate

                                       12
<PAGE>
         (b) (i) The audited consolidated balance sheets of the Borrower and its
Subsidiaries as at December 31, 2002, and the related consolidated statements of
income and of cash flows for the fiscal year ended December 31, 2002, reported
on by and accompanied by an unqualified report from KPMG LLP, copies of each of
which have heretofore been furnished to the Administrative Agent and each
Replacement Tranche B Lender, present fairly, in all material respects, the
consolidated financial condition of the Borrower and its Subsidiaries as at such
date, and the consolidated results of its operations and its consolidated cash
flows for the fiscal year then ended. The unaudited consolidated balance sheet
of the Borrower and its Subsidiaries as at March 31, 2003, and the related
unaudited consolidated statements of income and cash flows for the three-month
period ended on such date, present fairly, in all material respects, the
consolidated financial condition of the Borrower as at such date, and the
consolidated results of its operations and its consolidated cash flows for the
three-month period then ended (subject to normal year-end audit adjustments).
All such financial statements, including the related schedules and notes
thereto, have been prepared in accordance with GAAP applied consistently
throughout the periods involved (except as approved by the aforementioned firm
of accountants and disclosed therein and, in the case of the unaudited financial
statements referred to in the preceding sentence, except for the absence in
footnotes) and the applicable rules and regulation of the Securities Act. As of
December 31, 2002, neither Holdings nor any of its Subsidiaries has any material
Guarantee Obligations, contingent liabilities and liabilities for taxes, or any
long-term leases or unusual forward or long-term commitments, including any
interest rate or foreign currency swap or exchange transaction or other
obligation in respect of derivatives, that are not reflected in the most recent
financial statements as of and for the fiscal year ended December 31, 2002.

                  (ii) Since December 31, 2002 (i) there have not been any
events or states of fact which individually or in the aggregate would have a
Material Adverse Effect, and (ii) no change has occurred or is threatened which
individually or in the aggregate has had or is continuing to have a material
adverse effect on the prospects of the Borrower and its Subsidiaries taken as a
whole.

         2.4. Mortgages. With respect to each of the Mortgages, to the extent
reasonably requested by the Administrative Agent, within sixty (60) days
following the Replacement Tranche B Effective Date, the Loan Party signatory
thereto shall execute and deliver a mortgage amendment, which has the effect of
including all obligations of the Loan Parties in respect of the Replacement
Tranche B Term Loans as secured obligations under such Mortgage, and cause an
appropriate endorsement to the title policy (if any) issued in respect thereto
by the relevant title insurance company to be furnished to the Administrative
Agent, in each case in a form reasonably satisfactory to the Administrative
Agent.

         2.5. Counterparts. This Amendment may be executed by one or more of the
parties to this Amendment on any number of separate counterparts (including by
facsimile transmission), and all of said counterparts taken together shall be
deemed to constitute one and the same instrument. A set of the copies of this
Amendment signed by all the parties shall be lodged with the Borrower and the
Administrative Agent. The execution and delivery of the Amendment by any Lender
shall be binding upon each of its successors and assigns (including Transferees
of its commitments and Loans in whole or in part prior to effectiveness hereof)
and binding in respect of all of its commitments and Loans, including any
acquired subsequent to its execution and delivery hereof and prior to the
effectiveness hereof.

         2.6. Continuing Effect; No Other Amendments. Except as expressly
amended, modified and supplemented hereby, the provisions of the Credit
Agreement are and shall remain in full force and effect. This Amendment shall
not constitute a Amendment of any other provision of the Credit Agreement not
expressly referred to herein and shall not be construed as a Amendment or
consent to any further or future action on the part of the Borrower that would
require a Amendment or consent of the Required Lenders or Lenders, as the case
may be, or the Administrative Agent. This Amendment shall constitute a Loan
Document.

         2.7. Payment of Expenses. The Borrower agrees to pay and reimburse the
Administrative Agent for all of its out-of-pocket costs and reasonable expenses
incurred to date in connection with this Amendment and the other Loan Documents,
including, without limitation, the reasonable fees and disbursements of legal
counsel to the Administrative Agent.

         2.8. GOVERNING LAW. THIS AMENDMENT AND THE RIGHTS AND OBLIGATIONS OF
THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN
ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.
