the Borrower party thereto, as guarantors, the lenders party thereto (the
“Existing Lenders”) and Goldman Sachs Bank USA, as Administrative Agent and
Collateral Agent. Capitalized terms used but not otherwise defined in this
Amendment have the meanings specified in the Credit Agreement, as amended by
this Amendment (the “Amended Credit Agreement”).
The Borrower has requested the establishment on the Amendment No. 1 Effective
Date (as defined below) of Refinancing Term Loans made to the Borrower (the
“Tranche B Term Loans”), which Refinancing Term Loans will have the Maturity
Date and all other terms (other than the Applicable Rate) that are substantially
identical to those of the Original Tranche B Term Loans (as defined below).
Each Existing Lender whose name is set forth on Schedule 1.1(a) hereto (such
Existing Lenders being collectively referred to as the “Converting Tranche B
Term Lenders”) has agreed to make a Tranche B Term Loan on the Amendment No. 1
Effective Date by converting the principal amount of its Original Tranche B Term
Loan set forth on such Schedule opposite its name into a Tranche B Term Loan in
a like principal amount (such conversion being referred to as the “Conversion”),
in each case on the terms and subject to the conditions set forth herein.
Each Person (which may include any Existing Lender) whose name is set forth on
Schedule 1.1(b) hereto (such Persons being collectively referred to as the “New
Tranche B Term Lenders” and, together with the Converting Tranche B Term
Lenders, the “Tranche B Term Lenders”) has agreed to make a Tranche B Term Loan
on the Amendment No. 1 Effective Date in a principal amount not to exceed the
amount set forth on such Schedule opposite its name (such agreement being, with
respect to each New Tranche B Term Lender, its “New Tranche B Term Commitment”),
in each case on the terms and subject to the conditions set forth herein.
The Tranche B Term Loans to be made by any Converting Tranche B Term Lender will
be made solely through the Conversion. The Tranche B Term Loans to be made by
any New Tranche B Term Lender will be funded in cash in accordance with Sections
2.1(b) and 2.5 of the Amended Credit Agreement, and all the proceeds thereof
received by the Borrower shall be applied on the Amendment No. 1 Effective Date
to repay the entire principal amount of the Original Tranche B Term Loans that
shall not have been converted into the Tranche B Term Loans pursuant to the
Conversion. The repayment of the Original Tranche B Term Loans in accordance
with this paragraph (including pursuant to the Conversion), together with the
payment of all accrued and unpaid interest thereon through the Amendment No. 1
Effective Date, are collectively referred to as the “Refinancing”.
