Loans under the Revolving Credit Facility bear interest, at the Company’s option, at a rate equal to either (a) the LIBOR rate, plus an applicable margin ranging from 1.75% to 2.50% per annum, based upon the secured leverage ratio (as defined in the Credit Agreement) or (b) the prime lending rate, plus an applicable margin ranging from 0.75% to 1.50% per annum, based upon the senior secured net leverage ratio (as defined in the Credit Agreement). The obligations under the Credit Agreement and any swap obligations and banking services obligations owing to a lender (or an affiliate of a lender) thereunder are and will be guaranteed by the Company and each of the Company’s existing and subsequently acquired or organized direct and indirect domestic subsidiaries (other than certain immaterial domestic subsidiaries, certain Domestic Foreign Holding Companies, and certain domestic subsidiaries whose equity interests are owned directly or indirectly by certain foreign subsidiaries) (collectively, the “Loan Parties”). The obligations under the Credit Agreement and any such swap and banking services obligations are secured, subject to customary permitted liens and other agreed upon exceptions, by a perfected security interest in (i) all tangible and intangible assets of the Loan Parties, except for certain customary excluded assets, and (ii) all of the capital stock owned by the Loan Parties thereunder (limited, in the case of the stock of certain non-U.S. subsidiaries of the Company and Domestic Foreign Holding Companies, to 65% of the capital stock of such subsidiaries). The Credit Agreement contains customary representations and warranties and customary affirmative and negative covenants, including, among other things, restrictions on indebtedness, liens, investments, mergers, dispositions, prepayment of other indebtedness and dividends and other distributions. Under the terms of the Credit Agreement, the Company is required to comply with a maximum senior secured net leverage ratio and minimum interest coverage ratio covenants. On October 23, 2015, the Company borrowed $75.0 million under the Revolving Credit Facility, which was used to repay the $75.0 million outstanding at September 30, 2015 under the Existing Credit Agreement.
