Revolving Lenders”) will thereby (i) agree to the terms of this Amendment and
(ii) agree to convert its Existing Revolving Commitments into New Revolving
Commitments in a principal amount equal to the aggregate principal amount of

liens created under the Guarantee and Collateral Agreement and the other
Security Documents and the effectiveness and enforceability thereof for the
benefit of the New Term Loans and the New Revolving Commitments.

(f)  Prepayment of the Existing Term Loans.  The Existing Term Loans, including
all accrued, unpaid interest thereon, shall be paid simultaneously in full in
cash.

(g)  Fees.  The Administrative Agent shall have been reimbursed for all
reasonable expenses then due and payable for which invoices have been presented
(including reasonable fees, disbursements and other charges of counsel to the
Administrative Agent) and shall have received all fees required to be paid in
connection herewith  including for the account of:

(i) each Tranche A Term Lender executing and delivering a Lender Addendum
providing that it shall be a Tranche A Term Lender for Tranche A Term Loans in
an amount equal to its commitment to make Tranche A Term Loans prior to 9:00
a.m. (EST) on May 27, 2011, an upfront fee equal to 100 basis points of the
amount of such commitment to provide Tranche A Term Loans; and
 
(ii) each New Revolving Lender executing and delivering a Lender Addendum prior
to 9:00 a.m. (EST) on May 27, 2011, an upfront fee equal to 100 basis points of
the amount of its New Revolving Commitment as set forth on such Lender

New Revolving Commitments in excess of such Lender’s Existing Revolving
Commitment shall be entitled to an upfront fee pursuant to this paragraph (ii)
on such excess commitment amount.
 
All such amounts will be paid with cash on hand of the Borrower and its
Subsidiaries or with proceeds of Loans made on the Effective Date and will be
reflected in the funding instructions given by the Borrower to the

Administrative Agent and notified to it prior to the Effective Date and (ii) of
any Tranche A Term Lender will be such amount of Tranche A Term Loans set forth

(b)  For purposes hereof, a Person may become a party to the Credit Agreement as
amended hereby and a New Tranche B Term Lender or a Tranche A Term Lender, as
the case may be, as of the Effective Date by executing and delivering to the
Administrative Agent, on or prior to the Effective Date, a Lender Addendum in
its capacity as a Tranche A Term Lender or a New Tranche B Term Lender.  The
Borrower shall give notice to the Administrative Agent of the proposed Effective
Date not later than one Business Day prior thereto, and the Administrative Agent
shall notify each Existing Term Loan Lender, each New Tranche B Term Lender and
each Tranche A Term Lender thereof.
 
(c)  Each Tranche A Term Lender will make its Tranche A Term Loan on the
Effective Date and each New Tranche B Term Lender will make its Tranche B Term
Loan on the Effective Date, by making available to the Administrative Agent, in
the manner contemplated by Section 2.2 of the Credit Agreement (as amended
hereby), an amount equal to such Lender’s New Term Loan Commitment.  The
commitments of the Tranche A Term Lenders and the New Tranche B Term Lenders are
several and no such Lender will be responsible for any other such Lender’s
failure to make its New Term Loan.  The New Term Loans may from time to time be
Eurodollar Loans or Base Rate Loans, as determined by the Borrower and notified
to the Administrative Agent as contemplated by Sections 2.2 and 4.3 of the
Credit Agreement.  The Lenders having Existing Term Loans that are prepaid in
connection with the making of the New Term Loans shall be entitled to the
benefits of Section 4.11 of the Credit Agreement with respect thereto.

(d)  The obligation of each Tranche A Term Lender and New Tranche B Term Lender
to make New Term Loans on the Effective Date is subject to the satisfaction of
the conditions set forth in Section 11 of this Amendment.

(e)  On and after the Effective Date, each reference in the Credit Agreement to
“Term Loans” shall be deemed a reference to the New Term Loans contemplated
hereby, except as the context may otherwise require.  Notwithstanding the
foregoing, the provisions of the Credit Agreement with respect to
indemnification, reimbursement of costs and expenses, increased costs and break
funding payments (other than to the extent set forth in Section 12 of this
Amendment) shall continue in full force and effect with respect to, and for the
benefit of, each Existing Term Loan Lender in respect of such Lender’s Existing
Term Loans.
 
SECTION 13.  Representations and Warranties.  The Borrower hereby represents and
warrants that (a) each of the representations and warranties made by any Loan
Party in or pursuant to the Loan Documents shall be, after giving effect to this
Amendment, true and correct in all material respects as if made on and as of the
Effective Date, except to the extent such representations and warranties
expressly relate to an earlier time, in which case such representations and
warranties were true and correct in all material respects as of such earlier
time; provided that, to the extent any such representation and warranty is
already qualified by materiality or by reference to material adverse effect,
such representation shall be true and correct in all respects; provided further
that, each reference to the Credit Agreement therein shall be deemed to be a
reference to the Credit Agreement after giving effect to this Amendment and (b)
after giving effect to this Amendment, no Default or Event of Default shall have
occurred and be continuing.

SECTION 14.  Effects on Loan Documents.  Except as specifically amended herein,
all Loan Documents shall continue to be in full force and effect and are hereby
in all respects ratified and confirmed.  Except as otherwise expressly provided
herein, the execution, delivery and effectiveness of this Amendment shall not
operate as a waiver of any right, power or remedy of any Lender or the
Administrative Agent under any of the Loan Documents, nor constitute a waiver of
any provision of the Loan Documents.

SECTION 15.  GOVERNING LAW; WAIVER OF JURY TRIAL.  THIS AMENDMENT AND THE RIGHTS
AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH
AND BE GOVERNED BY THE LAW OF THE STATE OF NEW YORK.  EACH PARTY HERETO HEREBY
AGREES AS SET FORTH FURTHER IN SECTION 11.12 OF THE CREDIT AGREEMENT AS IF SUCH
SECTION WAS SET FORTH IN FULL HEREIN.

SECTION 16.  Loan Document.  This Amendment shall constitute a “Loan Document”
for all purposes of the Credit Agreement and the other Loan Documents.
 
SECTION 17.  Amendments; Execution in Counterparts.  This Amendment shall not
constitute an amendment of any other provision of the Credit Agreement not
referred to herein and shall not be construed as a waiver or consent to any
further or future action on the part of the Credit Parties that would require a
waiver or consent of the Required Lenders or the Administrative Agent.  Except
as expressly amended hereby, the provisions of the Credit Agreement are and
shall remain in full force and effect.  This Amendment may be executed in any
number of counterparts and by the different parties hereto on separate
counterparts, including by means of facsimile or electronic transmission, each
of which when so executed and delivered shall be an original, but all of which
shall together constitute one and the same instrument.

2.      The Assignor (a) makes no representation or warranty and assumes no

document furnished pursuant thereto, other than that the Assignor has not
created any adverse claim upon the interest being assigned by it hereunder and
that such interest is free and clear of any such adverse claim and (b) makes no
representation or warranty and assumes no responsibility with respect to the
financial condition of the Borrower, any of its Subsidiaries, any of its
