              prepayments with Net Proceeds from the issuance of Indebtedness
              permitted by Section 6.01(m) or 6.01(p), to the extent applicable)
              at and after the Incremental Effective Date, (1) to reduce in

              Borrowing and (2) thereafter, to reduce on a pro rata basis (based

              For purposes of determining any allocation made ratably or on a
              pro rata basis contemplated under this paragraph at any time, the
              amount of any Tranche D-2 Term Loan shall be the Dollar Equivalent
              of the principal amount thereof, determined using the Exchange
              Rate calculated as of the date of such prepayment. For purposes of
              determining the amount of any prepayment of Tranche D-2 Term
              Borrowings pursuant to Section 2.11(c) or 2.11(d), the applicable
              Exchange Rate on the date such prepayment is to be made shall be
              used.

Term Loans and New Revolving Facility Loans shall be secured by a Lien on the
Mortgaged Property that is the subject of such Mortgage, signed on behalf of the
record owner of such Mortgaged Property.

represents and warrants to the Administrative Agent and to each of the
Incremental Lenders that:

            (a) This Amendment has been duly authorized, executed and delivered
by the U.S. Borrower and constitutes a legal, valid and binding obligation of
the U.S. Borrower, enforceable in accordance with its terms, subject to (i) the
effects of bankruptcy, insolvency, moratorium, reorganization, fraudulent
conveyance or other similar laws affecting creditors' rights generally, (ii)
general principles of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law) and (iii) implied covenants of
good faith and fair dealing.

            (b) Neither the performance by any U.S. Transaction Party of the
Amendment Transactions, nor compliance by such U.S. Transaction Party with the
terms and provisions of the Reaffirmation Agreement (and, in the case of the
U.S. Borrower, this Amendment), will (i) violate (A) any provision of law,
statute, rule or regulation, or of the certificate or articles of incorporation
or other constitutive documents or by-laws of such U.S. Transaction Party, (B)
any applicable order of any court or any rule, regulation or order of any
Governmental Authority or (C) any provision of any indenture, certificate of
designation for preferred stock, agreement or other instrument to which any U.S.
Transaction Party or any of its subsidiaries is a party or by which any U.S.
Transaction Party or any of its subsidiaries or any of its or their property is
or may be bound, (ii) be in conflict with, result in a breach of or constitute
(alone or with notice or lapse of time or both) a default under, give rise to a
right of or result in any cancelation or acceleration of any right or obligation
(including any payment) or to a loss of a material benefit under any such
indenture, certificate of designation for preferred stock, agreement or other
instrument or (iii) result in the creation or imposition of any Lien upon or
with respect to any property or assets now owned or hereafter acquired by any
U.S. Transaction Party or any of its subsidiaries, other than the Liens created
by the Loan Documents.

            (c) The representations and warranties set forth in Article III of
the Credit Agreement are true and correct in all material respects on and as of
the Incremental Effective Date with the same effect as though made on and as of
such date, except to the extent such representations and warranties expressly
relate to an earlier date (in which case such representations and warranties
shall be true and correct in all material respects as of such earlier date).

            (d) Immediately prior to and after giving effect to this Amendment,
no Default or Event of Default shall have occurred and be continuing.

              SECTION 12. Effectiveness; Amendments. This Amendment shall become
effective as of the date first above written when the Administrative Agent shall
have received counterparts of this Amendment that, when taken together, bear the
signatures of the U.S. Borrower and the Incremental Lenders. This Amendment may

writing signed by the U.S. Borrower, the Administrative Agent and each
Incremental Lender.

under the Credit Agreement or any other Loan Document, and shall not alter,
modify, amend or in any way affect any of the terms, conditions, obligations,
covenants or agreements contained in the Credit Agreement or any other Loan
Document, all of which are ratified and affirmed in all respects and shall
continue in full force and effect. Nothing herein shall be deemed to entitle the
Borrowers to any future consent to, or waiver, amendment, modification or other
change of, any of the terms, conditions, obligations, covenants or agreements
contained in the Credit Agreement or any other Loan Document in similar or
different circumstances. After the date this Amendment becomes effective, any
reference to the Credit Agreement shall mean the Credit Agreement as modified
hereby. This Amendment shall constitute an "Incremental Facility Amendment", the
Incremental Lenders shall constitute "Lenders", the Reaffirmation Agreement
shall constitute a "Loan Document", the Tranche B-2 Term Loans shall constitute
"Incremental Extensions of Credit" and the Tranche B-2 Term Loan Commitments
shall constitute commitments in respect of Incremental Extensions of Credit, in
each case for all purposes of the Credit Agreement and the other Loan Documents.

AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

more counterparts, each of which shall constitute an original but all of which,
when taken together, shall constitute but one contract. Delivery of an executed
signature page to this Amendment by facsimile transmission shall be effective as
delivery of a manually signed counterpart of this Amendment.

              SECTION 16. Expenses. The U.S. Borrower agrees to reimburse the
Administrative Agent for its reasonable out-of-pocket expenses in connection
with this Amendment.

              SECTION 17. Headings. The Section headings used herein are for
convenience of reference only, are not part of this Amendment and are not to
affect the construction of, or to be taken into consideration in interpreting,
this Amendment.
