2.Amendments to Credit Agreement. Subject to the satisfaction of the conditions to effectiveness set forth in Section 3 of this Amendment and in reliance upon the representations and warranties set forth in Section 4 of this Amendment, the Credit Agreement is hereby amended as follows:

(a)Section 1.2 of the Credit Agreement is hereby amended by amending and restating the defined term "Applicable Margin" set forth therein as follows:

"Applicable Margin" shall mean the applicable rate per annum corresponding to the applicable Senior Net Leverage Ratio, all as set forth in the following table:

Senior Net Leverage Ratio	Prime Rate Loans	LIBOR Rate Loans

The Applicable Margin shall be adjusted quarterly, to the extent applicable, as of the first Business Day of the month following the date on which financial statements are required to be delivered pursuant to Section 9.8 hereof (including with respect to the last fiscal quarter of each fiscal year) after the end of each related fiscal quarter based on the Senior Net Leverage Ratio as of the last day of such fiscal quarter. Notwithstanding the foregoing, (a) until the first Business Day of the month following the date on which financial statements for the fiscal quarter ending March 31, 2019 are required to be delivered pursuant to Section 9.8 hereof, the Applicable Margin shall be (i) 7.25% with respect to Prime Rate Loans and (ii) 8.25% with respect to LIBOR Rate Loans, (b) if Borrowers fail to deliver the financial statements required by Section 9.8 hereof, and the related Compliance Certificate required by Section 9.8 hereof, by the respective date required thereunder after the end of any related fiscal quarter, if requested in writing by Agent or Required Lenders, the Applicable Margin shall be the rates corresponding to the Senior Net Leverage Ratio of > 3.00x in the foregoing table until such financial statements and Compliance Certificate are delivered (plus, if requested by Agent or Required Lenders, the Default Rate), (c) no reduction to the Applicable Margin shall become effective at any time when an Event of Default has occurred and is continuing; provided, that such a reduction shall occur on the date all such Events of Default have been cured or waived in accordance with Section 16.2(b) hereof, and (d) during the PIK Interest Period, the Applicable Margin shall be increased by an amount equal to the PIK Interest Rate, with 100% of such increase being paid in kind by adding such interest to the outstanding principal amount of the Term A Loan ("PIK Interest").
