On March 29, 2017, Frontier Communications Corporation amended its credit agreement, dated as of June 2, 2014, with CoBank, ACB, as administrative agent, and the other lenders party thereto, and its credit agreement, dated as of October 12, 2016, with CoBank, ACB, as administrative agent, and the other lenders party thereto (the Amendments). The Amendments provide that interest rate margins under each of these facilities will range from 0.875% to 3.875% for Base Rate borrowings and 1.875% to 4.875% for LIBOR borrowings, subject to adjustment based on our Total Leverage Ratio, as defined in each credit agreement. The interest rate on each of the facilities as of March 29, 2017 was LIBOR plus 3.875%. In addition, the Amendments provide Frontier with more flexible terms, the most significant of which is a change in the covenants to increase the maximum Leverage Ratio (as defined in the Amendments) to 5.25 to 1.0 initially, migrating to 5.0 to 1.0 beginning in the second quarter of 2018, 4.75 to 1.0 in the second quarter of 2019, and 4.5 to 1.0 in the second quarter of 2020. Under the Amendments, Frontier will be expanding the security package to include pledges of the equity interests in certain Frontier subsidiaries and guaranties by certain Frontier subsidiaries. Such increase in the maximum Leverage Ratio and expansion of the security package are the same as those contained in that certain first amended and restated credit agreement, dated as of February 27, 2017, with JPMorgan Chase Bank, N.A., as administrative agent, and the other lenders party thereto, previously filed with the Commission as Exhibit 10 under cover of Form 8-K on February 28, 2017.

The foregoing description of the Amendments is qualified in its entirety by reference to the full text of each Amendment, copies of which are filed as Exhibit 10.1 and 10.2 to this Report and incorporated herein by reference.
