Repayments of Outstanding Principal under Term Loan Facility

On August 1, 2017, the Company entered into an amendment (the “Third Amendment”) to the Second Amended and Restated Credit Agreement. The Third Amendment increased the borrowing limit under the revolving credit facility from $225 million to $325 million and reset the uncommitted accordion feature to $125 million for potential future expansion. Additionally, the Third Amendment increased the term loan balance from $65.6 million to $90.6 million. Under the Third Amendment, the Company is required to pay quarterly scheduled principal repayments of $2.3 million beginning in October 2017, with the final installment of $56.1 million due upon maturity in May 2021. Borrowings under the revolving credit facility may be repaid at any time through May 2021, the date of maturity date of the Senior Credit Facilities. The Company may voluntarily prepay loans or reduce commitments under the Senior Credit Facilities, in whole or in part, without premium or penalty, subject to certain minimum principal amounts.

On February 26, 2018, the Company entered into a fourth amendment (the “Fourth Amendment”) to the Second Amended and Restated Credit Agreement. The Fourth Amendment increases the maximum permitted consolidated leverage ratio from 3.00 to 3.50, increases the maximum consolidated leverage ratio for permitted acquisitions and stock repurchases from 2.50 to 3.00, increases the maximum permitted consolidated leverage ratio for a designated acquisition from 3.00 to 3.50, and increases the maximum leverage ratio for four consecutive quarters following a designated acquisition from 3.50 to 4.00. Certain other technical changes were made to the Second Amended and Restated Credit Agreement as a result of the Fourth Amendment and are not considered material.
