The Amendment Agreement amends the Credit Agreement to, among other things, make changes to the covenants and other provisions therein and to change the interest rate applicable to borrowings under (A) the senior secured term loan A facility to (i) for base rate loans, a base rate equal to the highest of (x) the prime rate, (y) the federal funds rate plus 50 basis points and (z) the one-month LIBOR rate plus 100 basis points (the highest of (x), (y) and (z), the “base rate”), plus a leverage-based margin of 100 to 312.5 basis points and (ii) for Eurodollar rate loans, the applicable LIBOR rate (subject to a 0.00% LIBOR floor) plus a leverage-based margin of 200 to 412.5 basis points, and (B) the senior secured term loan B facility to (i) for base rate loans, the base rate plus a leverage-based margin of 300 to 337.5 basis points and (ii) for Eurodollar rate loans, the applicable LIBOR rate (subject to a 1.00% LIBOR floor) plus a leverage-based margin of 400 to 437.5 basis points.

In addition, pursuant to the Amendment Agreement, immediately after the effectiveness of the amendments described above, the Company established $80,000,000 of increased revolving commitments and borrowed $80,000,000 of increased term B loans (such increased commitments and loans, collectively, the “Incremental Facilities”) on the same terms as the Company’s existing revolving commitments and term B loans, respectively.
