B.            The Borrower desires to amend the Credit Agreement to, among other things, permit the incurrence of additional Indebtedness, in the form of new Tranche C Term Loans, to be used for the purpose of prepaying the Tranche B Term Loans, to replace the existing Funded Letter of Credit Facility (the “Existing Funded L/C Facility”) with a new funded letter of credit facility and to increase the Borrower’s ability to make Restricted Payments, Permitted Acquisitions and Capital Expenditures.

C.            Each existing Lender with outstanding Tranche B Term Loans (an “Existing Tranche B Term Loan Lender”) and each Lender that is a Funded L/C Participant (an “Existing Funded L/C Participant”) that executes and delivers to the Administrative Agent a consent to this Amendment together with a conversion notice in the form attached hereto as Exhibit A (each, a “Conversion Notice”), will be considered a continuing Lender (each a “Continuing Lender”) and will exchange all of its outstanding Tranche B Term Loans for Tranche C Term Loans on the Amendment Effective Date and will exchange its reversionary interest in the existing Credit Linked Deposit (the “Existing Credit Linked Deposit”) for a reversionary interest in the Credit Linked Deposit established pursuant to this Amendment.

D.            Each Person (other than a Continuing Lender) that agrees to make Tranche C Term Loans or to provide a Funded Letter of Credit Commitment on the Amendment Effective Date (an “Additional Lender”) will execute and deliver to the Administrative Agent, on or prior to the Amendment Effective Date, a Lender Addendum, in the form attached hereto as Exhibit B and make such Tranche C Term Loans to the Borrower or make a deposit with the Revolving Administrative Agent in the manner contemplated by Section 2 of this Amendment.
