Notes.

June 17, 2015,

the Company issued

$450

million aggregate principal amount of

5.75%

senior unsecured notes due

2022

(the “Notes”). The Notes mature on

June 15, 2022

and interest is payable on

June

and

The Notes were issued pursuant to an indenture dated as of

the “Indenture”). The Indenture provides for early redemption of the Notes, at the option of the Company, at the prices and subject to the terms specified in the Indenture. The Indenture includes certain covenants relating to debt incurrence, liens, restricted payments, asset sales and transactions with affiliates, changes in control and mergers or sales of all or substantially all of the Company’s assets. The Indenture also provides for customary events of default (subject, in certain cases, to customary grace periods).

Senior Credit Facilities.

June 30, 2015,

the Company entered into a Credit Agreement (the “Credit Agreement”) among the Company, as borrower, the lenders party thereto, JPMorgan Chase Bank, N.A. (“JPMorgan”), as administrative agent, and the other agents party thereto. The Credit Agreement provided for a

five

-year revolving credit facility in an aggregate principal amount of

$200

million (the “Revolving Credit Facility”) and a

five

-year term loan facility in an aggregate principal amount of

$100

million (the “Term Loan Facility”). Concurrently with its entry into the Credit Agreement, the Company borrowed the full amount of the Term Loan Facility. The Revolving Credit Facility also gives the Company the ability to issue letters of credit, which reduce the amount available for borrowing under the Revolving Credit Facility. On

May 1, 2017,

the Company and the lenders amended and restated the Credit Agreement (the “Amended and Restated Credit Agreement”) and incurred

$750

million of senior secured loans (the “New Loans”) which were used, together with cash on hand, to finance the NewWave acquisition, repay in full the Term Loan Facility and pay related fees and expenses.

The New Loans consist of a

five

-year term “A” loan in an aggregate principal amount of

$250

million (the “Term Loan A”) and a

seven

-year term “B” loan in an aggregate principal amount of

$500

million (the “Term Loan B” and, together with the Term Loan A and the Revolving Credit Facility, the “Senior Credit Facilities”). The obligations under the Amended and Restated Credit Agreement are guaranteed by the Company’s wholly owned domestic subsidiaries and are secured, subject to certain exceptions, by substantially all assets of the Company and the guarantors.

The interest margins applicable to the Senior Credit Facilities are, at the Company’s option, equal to either the London Interbank Offered Rate (“LIBOR”) or a base rate, plus an applicable margin equal to, (i) with respect to the Term Loan A, and the Revolving Credit Facility,

1.50%

2.25%

for LIBOR loans and

0.50%

1.25%

for base rate loans, determined on a quarterly basis by reference to a pricing grid based on the Company’s total net leverage ratio and (ii) with respect to the Term Loan B, (

) for any day on or prior to

April 22, 2018,

2.25%

for LIBOR loans and

1.25%

for base rate loans and (y) for any date after

April 22, 2018,

1.75%

for LIBOR loans and

0.75%

for base rate loans. The Term Loan A

may

be prepaid at any time without premium and amortizes quarterly at a rate (expressed as a percentage of the original principal amount) of

2.5%

per annum for the

first

year after funding,

5.0%

per annum for the

second

year after funding,

7.5%

per annum for the

third

year after funding and

10.0%

per annum for the

fourth

and

fifth

years after funding, with the outstanding balance due upon maturity. The Term Loan B amortizes quarterly at a rate (expressed as a percentage of the original principal amount) of

1.0%

per annum, with the outstanding balance due upon maturity. The Term Loan B is subject to a

1.0%

prepayment premium if prepaid in connection with a “Repricing Transaction” (as defined in the Amended and Restated Credit Agreement) within

six

months of the effective date of the Repricing Amendment (as defined below), benefits from certain “most favored nation” pricing protections and is

not

subject to the financial maintenance covenants under the Amended and Restated Credit Agreement. Other than as set forth above, the New Loans are subject to terms substantially similar to those under the Credit Agreement.

The Company

may,

subject to certain specified terms and provisions, obtain additional credit facilities of up to

$425

million under the Amended and Restated Credit Agreement plus an unlimited amount so long as, on a pro forma basis, the Company’s First Lien Net Leverage Ratio (as defined in the Amended and Restated Credit Agreement) is

greater than

1.80

1.00.

The Amended and Restated Credit Agreement contains customary representations, warranties and affirmative and negative covenants as well as customary events of default. The Amended and Restated Credit Agreement also requires the Company to maintain specified ratios of total net indebtedness and

first

lien net indebtedness to consolidated operating cash flow. Refer to note
