          NOW, THEREFORE, in consideration of the mutual agreements herein contained and other good and
valuable consideration, the sufficiency and receipt of which are hereby acknowledged, the parties
hereto hereby agree as follows:

circumstance apply to or restrict any payment (whether in respect of a purchase,
repurchase, redemption, defeasance, prepayment or otherwise) that the Borrower is
obligated to make in respect of any Existing Senior Notes or any New Senior Notes;
provided, however, that, except for any actions permitted under clause (i) or (iii)

to, take any action, or omit to take any action, if, as the direct result of such
action or omission, any Existing Senior Notes or any New Senior Notes shall become

Senior Notes Documents. Each









 



6


Lender party hereto irrevocably (i) consents to such amendments,
supplements or other modifications to the Security Documents as the Administrative Agent determines
to be required or desired in order to secure thereunder obligations of the Borrower and the
Subsidiaries under the New Senior Notes Documents on substantially the same terms as the
obligations of the Borrower and the Subsidiaries under the Existing Senior Notes Documents are
secured thereunder, and to provide to the New Senior Notes, and the holders thereof, all the other
rights, powers and privileges that are provided for thereunder with respect to the Existing Senior
Notes and the holders thereof, (ii) authorizes and directs the Administrative Agent to execute and
deliver such agreement or agreements as shall effectuate such amendments, supplements or other
modifications, in each case without any further consent, authorization or other action by such
Lender, and (iii) agrees that such Lender shall not have any right of action whatsoever against the
Administrative Agent as a result of any action taken by the Administrative Agent pursuant to this
paragraph. Without limiting the foregoing, each Lender party hereto consents to (A) the amendment

and the Guarantees of the Subsidiaries in respect thereof and (B) the amendment of the term
“Secured Parties” to include each holder of the New Senior Notes.




          (b) Each Lender party hereto acknowledges that, as a condition precedent under the First Lien
Loan Documents to the issuance of the New Senior Notes, the Liens securing the New Senior Notes and
the holders thereof are required to be subject to the terms of the Intercreditor Agreement. Each

to the Intercreditor Agreement as the Administrative Agent determines to be required or desired in
order to subject the Liens securing the New Senior Notes, and the rights, powers and privileges of
the holders of the New Senior Notes, to the provisions of the Intercreditor Agreement on
substantially the same terms as such provisions apply to the Liens securing the Existing Senior
Notes and the rights, powers and privileges of the holders of the Existing Senior Notes, (ii)
authorizes and directs the Administrative Agent to execute and deliver such agreement or agreements
as shall effectuate such amendments, supplements or other modifications, in each case without any
further consent, authorization or other action by such Lender, and (iii) agrees that such Lender
shall not have any right of action whatsoever against the Administrative Agent as a result of any
action taken by the Administrative Agent pursuant to this paragraph.




          (c) The Administrative Agent shall have the benefit of the provisions of Article IX of the
Credit Agreement with respect to all actions taken by it pursuant to this Section to the full
extent thereof.




          (d) The Loans and other Term Obligations are hereby designated as “Senior Indebtedness” for
purposes of the New Senior Notes Indenture.




          (e) The Lenders party hereto agree that, in respect of any Prepayment Event arising from the
incurrence of any New Senior Notes, the Borrower shall be deemed to be in compliance with Section
2.09(e) so long as the Borrower shall have










 



7



given the notice contemplated by such Section in
connection with such Prepayment Event on or prior to the Prepayment Date with respect thereto.

amount of the Loans of such Lender outstanding on such date. The Amendment Fees shall be payable
in immediately available funds on, and subject to the occurrence of, the Amendment Effective Date.




          SECTION 6. Conditions to Effectiveness. This Amendment shall become effective on and as of

Required Lenders.

rights and remedies of the Lenders, the Administrative Agent (or any sub-agent thereof) or the
Arrangers 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
