Interest Rates

Borrowings under the New Credit Agreement may be incurred in U.S. Dollars, Sterling, Euros, Japanese Yen or any other currency approved by the Administrative Agent and the Lenders, subject to certain qualifications described in the New Credit Agreement. Regardless of currency, all borrowings under the New Credit Agreement may, at the Company’s option, be incurred as adjusted term SOFR loans (“Term Benchmark Loans”), adjusted daily simple RFR loans (“RFR Loans”) or alternate base rate loans (“ABR Loans”).

Term Benchmark Loans will accrue interest, for any interest period, at (a) a base rate per annum equal to (x) the Adjusted Term SOFR Rate, (y) the Adjusted EURIBOR Rate or (z) the Adjusted TIBOR Rate (each, as defined below), as applicable, plus 1.25%.

RFR Loans will accrue interest, for any interest period, at (a) a base rate per annum equal to the Adjusted Daily Simple RFR (as defined below), plus 1.25%.

ABR Loans will accrue interest, for any interest period, at (a) the rate of interest last quoted by The Wall Street Journal as the “Prime Rate” in the U.S. (or such other methodology as specified in the New Credit Agreement) in effect on such day, (b) the greater of (1) the Federal Funds Effective Rate (as defined in the New Credit Agreement) in effect on such day and (2) the Overnight Bank Funding Rate (as defined in the New Credit Agreement) in effect on such day plus ¹⁄₂ of 1.00% and (c) the Adjusted Term SOFR Rate for a one month interest period (or if such day is not a business day, the immediately preceding business day) (determined after giving effect to any applicable

“floor”) plus 1.00%; provided that, the Adjusted Term SOFR Rate for any day shall be based on the Term SOFR Rate (as defined below), subject to the interest rate floors set forth in the New Credit Agreement, plus (b) an applicable rate equal to 0.25%.

After the completion of the Company’s first full fiscal quarter occurring after the Closing Date, the applicable rate for borrowings under the Revolving Credit Facility may be increased if the Company’s total net leverage ratio (as described below) increases (or decreased if, after any applicable increase, the Company’s total net leverage ratio decreases).

Certain Covenants and Events of Default

The New Credit Agreement contains certain affirmative and negative covenants that are customary for credit agreements of this nature. The negative covenants include, among other things, limitations on asset sales, mergers and acquisitions, indebtedness, liens, investments and transactions with affiliates; provided that such negative covenants may be adjusted as specified in the New Credit Agreement upon the Company’s election following the achievement of an investment-grade rating for any class of senior, unsecured, non-credit enhanced, long-term

The New Credit Agreement includes customary events of default that include, among other things, non-payment defaults, inaccuracy of representations and warranties, covenant defaults, cross default to material indebtedness, bankruptcy and insolvency defaults, material judgment defaults, ERISA defaults and a change of control default. The occurrence of an event of default could result in the acceleration of the obligations under the New Credit Agreement and cross-default other indebtedness of the Company.
