Pursuant to Section 2.13 of the Credit Agreement, the Borrower may establish Incremental Term Loans by, among other things, entering into one or more Increase Joinders pursuant to the terms and conditions of the Credit Agreement with each Lender and/or additional lender agreeing to provide such Incremental Term Loans (each such Lender or additional lender agreeing to provide 2016 Term Loans (as defined below) and any permitted assignees thereof in accordance with the Credit Agreement, are referred to herein as “2016 Term Loan Lenders).
The Borrower has requested that the 2016 Term Loan Lenders party hereto extend credit to the Borrower in the form of Incremental Term Loans in an aggregate principal amount of $250,000,000 (the “2016 Term Loan Facility”; the loans thereunder, “2016 Term Loans”), and the 2016 Term Loan Lenders party hereto as of the date hereof have indicated their willingness to lend such 2016 Term Loans on the terms and subject to the conditions herein.
In connection with the advance of the 2016 Term Loans, the Borrower, the Agent and the 2016 Term Loan Lenders have agreed to make certain technical amendments to the Credit Agreement as contemplated by Section 2.13 of the Credit Agreement.
Therefore, in consideration of the premises and agreements, provisions and covenants herein contained, the parties hereto agree as follows:

Accordingly Section 2.01 is hereby amended to (a) make the first two sentences of existing Section 2.01 as a new clause (a), (b) renumber the last two sentences of existing Section 2.01 as a new clause (c) and (c) insert the following clause (b) above such new clause (c):

To the extent not previously paid, all 2016 Term Loans shall be due and payable on April 25, 2021 [the date that is five years after the 2016 Term Incremental Effective Date], together with accrued and unpaid interest on the principal amount to but excluding the date of payment.
