On July 31, 2019, we entered into a Third Amended and Restated Credit Agreement (the "Third Amended Credit Agreement"). The Third Amended Credit Agreement is a syndicated loan agreement with Wells Fargo Bank, National Association and other parties. The Third Amended Credit Agreement amends and restates in its entirety our previously outstanding Second Amended and Restated Credit Agreement and all amendments thereto. The Third Amended Credit Agreement provides for a term loan of $150 million and a revolving credit commitment up to an aggregate amount of $600 million, inclusive of sub-facilities for multicurrency borrowings, standby letters of credit and swingline loans. On

July 31, 2024, all principal, interest and other amounts outstanding under the Third Amended Credit Agreement are payable in full. At any time prior to the maturity date, we may repay any amounts owing under all term loans and revolving credit loans in whole or in part, without premium or penalty, other than breakage fees (as defined in the Third Amended Credit Agreement).

Revolving credit loans denominated in dollars and term loans made under the Third Amended Credit Agreement bear interest, at our election, at either the Base Rate or the Eurocurrency Rate (as such terms are defined in the Third Amended Credit Agreement) plus the Applicable Margin (as defined in the Third Amended Credit Agreement). Revolving credit loans denominated in an Alternative Currency (as defined in the Third Amended Credit Agreement) bear interest at the Eurocurrency Rate plus the Applicable Margin. Swingline loans bear interest at the Base Rate plus the Applicable Margin (as defined in the Third Amended Credit Agreement). Interest on each loan featuring the Base Rate is due and payable on the last business day of each calendar quarter commencing December 31, 2019; interest on each loan featuring the Eurocurrency Rate is due and payable on the last day of each interest period applicable thereto, and if such interest period extends over three months, at the end of each three-month interval during such interest period.

The Third Amended Credit Agreement is collateralized by substantially all of our assets. The Third Amended Credit Agreement contains affirmative and negative covenants, representations and warranties, events of default and other terms customary for loans of this nature. In particular, the Third Amended Credit Agreement requires that we maintain certain financial covenants, as follows:

(1)	Maximum Consolidated Total Net Leverage Ratio (as defined in the Third Amended Credit Agreement) as of any fiscal quarter end.

(2)	Minimum ratio of Consolidated EBITDA (as defined in the Third Amended Credit Agreement and adjusted for certain expenditures) to Consolidated interest expense (as defined in the Third Amended Credit Agreement) for any period of four consecutive fiscal quarters.

(3)	Maximum level of the aggregate amount of all Facility Capital Expenditures (as defined in the Third Amended Credit Agreement) in any fiscal year.

As of December 31, 2019, we believe we were in compliance with all covenants set forth in the Third Amended Credit Agreement.

As of December 31, 2019, we had outstanding borrowings of $440 million under the Third Amended Credit Agreement, with additional available borrowings of approximately $133.8 million, based on the leverage ratio required pursuant to the Third Amended Credit Agreement. Our interest rate as of December 31, 2019 was a fixed rate of 2.62% on $175 million as a result of an interest rate swap (see Note 9) and a variable floating rate of 3.30% on $265 million. Our interest rate as of December 31, 2018 was a fixed rate of 2.12% on $175 million as a result of an interest rate swap and a variable floating rate of 3.52% on $213.5 million.
