The Amendment provides for, among other things, a new senior secured revolving credit facility with aggregate commitments of $300,000,000 (the "Refinancing Revolving Facility").  The Refinancing Revolving Facility replaces the Existing Revolving Facility.  The maturity date for loans under the Refinancing Revolving Facility is April 18, 2023.

Loans under the Refinancing Revolving Facility will bear interest at a rate equal to, at the election of the Company, Adjusted LIBOR plus an applicable margin equal to 1.625% per annum or a base rate plus an applicable margin equal to 0.625% per annum, subject in each case to a decrease of (a) 12.5 basis points in the event that, and for so long as, the Net Leverage Ratio (as defined in the Amended Credit Agreement) is less than 2.00 to 1.00 and greater than or equal to 1.00 to 1.00 as of the last day of the preceding fiscal quarter and (b) 25 basis points in the event that, and for so long as, the Net Leverage Ratio is less than 1.00 to 1.00 as of the last day of the preceding fiscal quarter.  The Company will pay certain fees under the Credit Agreement, including (a) a commitment fee of 0.30% per annum on the undrawn portion of the Refinancing Revolving Facility (subject to step-downs to 0.25% and 0.20% at the same levels described above), (b) a fronting fee of 0.125% per annum on the average daily undrawn amount of, plus unreimbursed amounts in respect of disbursements under, letters of credit issued under the Refinancing Revolving Facility and (c) customary annual administration fees.
