Repayment of all then outstanding principal, interest, fees and costs is due at the end of the Term (as defined in the Credit Agreement).

With respect to Revolving B Loans (as defined in the Credit Agreement), for any day, the rate per annum is a tiered pricing based upon the Consolidated Debt to Consolidated EBITDA Ratio. The applicable rate for Revolving B Loans that are Base Rate Loans range between 0.20% and 1.15%. and the applicable rate for Revolving B Loans that are Term SOFR/Term SOFR Daily Floating Rate range between 1.20% and 2.15%
