WITNESSETH:

WHEREAS, the Borrower has entered into that certain First Lien Credit Agreement, dated as of August 20, 2015 (as amended, amended and restated, supplemented or otherwise modified prior to the date hereof, the “Credit Agreement”), among the Borrower, Holding (as defined therein), the several Lenders party thereto from time to time, the Administrative Agent, and the Collateral Agent;

WHEREAS, immediately prior to the effectiveness of this First Amendment, in accordance with Subsection 2.9 of the Credit Agreement, the Borrower has requested Supplemental Term Loan Commitments in an aggregate principal amount of $40.0 million pursuant to an Increase Supplement (the “Increase Supplement”) dated as of the date hereof, by and among the Borrower, each Lender party thereto and the Administrative Agent.

“First Amendment Effective Date”: the date on which each of the conditions set forth or referred to in Section 3 of the First Amendment is satisfied or waived.

(b)Subsection 3.4(a) of the Credit Agreement is hereby amended by deleting the final sentence thereof and replacing it with the following sentence:

(c)Subsection 3.4(i) of the Credit Agreement is hereby amended and restated in its entirety as follows:

(i) Notwithstanding the foregoing, if on or prior to the date that is one year after the First Amendment Effective Date the Borrower makes a voluntary prepayment (or mandatory prepayment with the proceeds of Specified Refinancing Term Loans) of all or any portion of the outstanding Initial Term Loans pursuant to a Repricing Transaction, the Borrower shall pay to the Administrative Agent, for the ratable account of each Initial Term Loan Lender, a prepayment premium of 1.0% of the aggregate principal amount of Initial Term Loans being prepaid. If, on or prior to the date that is one year after the First Amendment Effective Date, any Initial Term Loan Lender is replaced pursuant to subsection 10.1(g) in connection with any amendment of this Agreement (including in connection with any refinancing transaction permitted under subsection 10.6(g) to replace the Initial Term Loans) that results in a Repricing Transaction, such Lender (and not any Person who replaces such Lender pursuant to subsection 2.5(e) or 10.1(g)) shall receive a fee equal to 1.0% of the principal amount of the Initial Term Loans of such Lender assigned to a replacement Lender pursuant to subsection 2.5(e) or 10.1(g).

2

(b)Without limiting the foregoing, each of the Loan Parties party to the Guarantee and Collateral Agreement or any other Security Documents, in each case as amended, supplemented or otherwise modified from time to time, hereby (i) acknowledges and agrees that the Supplemental Term Loans incurred pursuant to the Increase Supplement are Initial Term Loans, (ii) acknowledges and agrees that all of its obligations under the Guarantee and Collateral Agreement and the other Security Documents to which it is a party are reaffirmed and remain in full force and effect on a continuous basis, (iii) reaffirms each Lien granted by each Loan Party to the Collateral Agent for the benefit of the Secured Parties and reaffirms the guaranties made pursuant to the Guarantee and Collateral Agreement, (iv) acknowledges and agrees that the grants of security interests by and the guaranties of the Loan Parties contained in the Guarantee and Collateral Agreement and the other Security Documents are, and shall remain, in full force and effect after giving effect to the First Amendment and the incurrence of the Supplemental Term Loans under the Increase Supplement, and (v) agrees that the Borrower Obligations and the Guarantor Obligations (each as defined in the Guarantee and Collateral Agreement) include, among other things and without limitation, the prompt and complete payment and performance by the Borrower when due and payable (whether at the stated maturity, by acceleration or otherwise) of principal and interest on the Supplemental Term Loans incurred pursuant to the Increase Supplement.
