            principal thereon prior to the date six months after the then Final
            Maturity Date, (iv) not be guaranteed by or have any recourse to the

            (c) in this definition shall not apply to any such accretion or
            issuance of such pay-in-kind notes). The Original 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

      (f)   Incumbency Certificates of the Loan Parties. The Administrative

      2.3. Representations and Warranties.

      (a)   The Borrower represents and warrants to each Lender that as of the
effective date of this Amendment: (i) this Amendment constitutes the legal,
valid and binding obligation of the Borrower, enforceable against it in
accordance with its terms, except as such enforcement may be limited by
bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or
similar laws affecting


                                       10
<PAGE>
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 to an earlier
date, in which case such representations and warranties shall have been true and
correct in all material respects on and as of such earlier date); and (iii) no
Default or Event of Default shall have occurred and be continuing as of the date
hereof.

      (b)   (i)   The audited consolidated balance sheets of the Borrower and
its Subsidiaries as at December 31, 2003, and the related consolidated
statements of income and of cash flows for the fiscal year ended December 31,
2003, 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 C Term 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 June 27,
2004, 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, 2003, 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, 2003.

            (ii)  Since December 31, 2003 (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 C 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 C Term Loans as secured obligations under such Mortgage, and furnish a
title report with respect to each Mortgaged Property, in each case form and
substance 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.
