Senior Credit Agreement

On April 11, 2018, the Company amended and restated its Senior Credit Agreement to (1) issue a new $2.4 billion Term Loan, (2) increase the total commitments under the Revolving Credit Facility from $1.0 billion to $1.25 billion, (3) extend the maturity date of the Revolving Credit Facility to April 11, 2023, (4) lower the applicable interest rate margins and commitment fees under the Revolving Credit Facility, and (5) amend certain other terms and conditions under the Senior Credit Agreement. The proceeds from the new Term Loan were used to repay the outstanding balances on the 2014 Term Loan, 2015 Term Loan, and Revolving Credit Facility and for general corporate purposes. This transaction was accounted for as an extinguishment of the 2014 Term Loan and 2015 Term Loan.

Terms of the Senior Credit Agreement

The Senior Credit Agreement, as amended, requires SBA Senior Finance II to maintain specific financial ratios, including (1) a ratio of Consolidated Net Debt to Annualized Borrower EBITDA not to exceed 6.5 times for any fiscal quarter, (2) a ratio of Consolidated Net Debt (calculated in accordance with the Senior Credit Agreement) to Annualized Borrower EBITDA for the most recently ended fiscal quarter not to exceed 6.5 times for 30 consecutive days and (3) a ratio of Annualized Borrower EBITDA to Annualized Cash Interest Expense (calculated in accordance with the Senior Credit Agreement) of not less than 2.0 times for any fiscal quarter. The Senior Credit Agreement contains customary affirmative and negative covenants that, among other things, limit the ability of SBA Senior Finance II and its subsidiaries to incur indebtedness, grant certain liens, make certain investments, enter into sale leaseback transactions, merge or consolidate, make certain restricted payments, enter into transactions with affiliates, and engage in certain asset dispositions, including a sale of all or substantially all of their property. The Senior Credit Agreement is also subject to customary events of default. Pursuant to the Second Amended and Restated Guarantee and Collateral Agreement, amounts borrowed under the Revolving Credit Facility, the Term Loans and certain hedging transactions that may be entered into by SBA Senior Finance II or the Subsidiary Guarantors (as defined in the Senior Credit Agreement) with lenders or their affiliates are secured by a first lien on the membership interests of SBA Telecommunications, LLC, SBA Senior Finance, LLC and SBA Senior Finance II and on substantially all of the assets (other than leasehold, easement and fee interests in real property) of SBA Senior Finance II and the Subsidiary Guarantors.

The Senior Credit Agreement, as amended, permits SBA Senior Finance II, without the consent of the other lenders, to request that one or more lenders provide SBA Senior Finance II with increases in the Revolving Credit Facility or additional term loans provided that after giving effect to the proposed increase in Revolving Credit Facility commitments or incremental term loans the ratio of Consolidated Net Debt to Annualized Borrower EBITDA would not exceed 6.5 times. SBA Senior Finance II’s ability to request such increases in the Revolving Credit Facility or additional term loans is subject to its compliance with customary conditions

set forth in the Senior Credit Agreement including compliance, on a pro forma basis, with the financial covenants and ratios set forth therein and, with respect to any additional term loan, an increase in the margin on existing term loans to the extent required by the terms of the Senior Credit Agreement. Upon SBA Senior Finance II’s request, each lender may decide, in its sole discretion, whether to increase all or a portion of its Revolving Credit Facility commitment or whether to provide SBA Senior Finance II with additional term loans and, if so, upon what terms.

Revolving Credit Facility under the Senior Credit Agreement

As amended, the Revolving Credit Facility consists of a revolving loan under which up to $1.25 billion aggregate principal amount may be borrowed, repaid and redrawn, based upon specific financial ratios and subject to the satisfaction of other customary conditions to borrowing. Amounts borrowed under the Revolving Credit Facility accrue interest, at SBA Senior Finance II’s election, at either (1) the Eurodollar Rate plus a margin that ranges from 112.5 basis points to 175.0 basis points or (2) the Base Rate plus a margin that ranges from 12.5 basis points to 75.0 basis points, in each case based on the ratio of Consolidated Net Debt to Annualized Borrower EBITDA, calculated in accordance with the Senior Credit Agreement. In addition, SBA Senior Finance II is required to pay a commitment fee of between 0.20% and 0.25% per annum on the amount of unused commitment. If not earlier terminated by SBA Senior Finance II, the Revolving Credit Facility will terminate on, and SBA Senior Finance II will repay all amounts outstanding on or before, April 11, 2023. The proceeds available under the Revolving Credit Facility may be used for general corporate purposes. SBA Senior Finance II may, from time to time, borrow from and repay the Revolving Credit Facility. Consequently, the amount outstanding under the Revolving Credit Facility at the end of the period may not be reflective of the total amounts outstanding during such period.

During the year ended December 31, 2019, the Company borrowed $755.0 million and repaid $590.0 million of the outstanding balance under the Revolving Credit Facility. As of December 31, 2019, the balance outstanding under the Revolving Credit Facility was $490.0 million accruing interest at 3.13% per annum. In addition, SBA Senior Finance II was required to pay a commitment fee of 0.20% per annum on the amount of the unused commitment. As of December 31, 2019, SBA Senior Finance II was in compliance with the financial covenants contained in the Senior Credit Agreement.

Subsequent to December 31, 2019, the Company borrowed $250.0 million and repaid $505.0 million of the outstanding balance under the Revolving Credit Facility. As of the date of this filing, $235.0 million was outstanding under the Revolving Credit Facility.

Repricing Amendment to the Senior Credit Agreement

On November 19, 2019, the Company amended its Senior Credit Agreement, primarily to reduce the stated rate of interest applicable to the Company’s senior secured term loan. As amended, the senior secured term loan accrues interest, at SBA Senior Finance II’s election, at either the Base Rate plus 75 basis points (with a zero Base Rate floor) or the Eurodollar Rate plus 175 basis points (with a zero Eurodollar Rate floor).

2018 Term Loan

On April 11, 2018, the Company, through its wholly owned subsidiary, SBA Senior Finance II LLC, obtained a new term loan (the “2018 Term Loan”) under the amended and restated Senior Credit Agreement. The 2018 Term Loan consists of a senior secured term loan with an initial aggregate principal amount of $2.4 billion that matures on April 11, 2025. Prior to November 19, 2019, the 2018 Term Loan accrued interest, at SBA Senior Finance II’s election at either the Base Rate plus 100 basis points (with a zero Base Rate floor) or the Eurodollar Rate plus 200 basis points (with a zero Eurodollar Rate floor). The 2018 Term Loan was issued at 99.75% of par value. As of December 31, 2019, the 2018 Term Loan was accruing interest at 3.55% per annum. Principal payments on the 2018 Term Loan commenced on September 30, 2018 and are being made in quarterly installments on the last day of each March, June, September, and December in an amount equal to $6.0 million. The Company incurred financing fees of approximately $16.8 million in relation to this transaction, which are being amortized through the maturity date. The proceeds from the 2018 Term Loan were used (1) to retire the outstanding $1.93 billion in aggregate principal amount of the 2014 Term Loan and 2015 Term Loan, (2) to pay down the existing outstanding balance under the Revolving Credit Facility, and (3) for general corporate purposes.

During the year ended December 31, 2019, the Company repaid an aggregate of $24.0 million of principal on the 2018 Term Loan. As of December 31, 2019, the 2018 Term Loan had a principal balance of $2.4 billion.

On December 3, 2019, the Company, through its wholly owned subsidiary, SBA Senior Finance II LLC, entered into a series of interest rate swaps on a portion of its 2018 Term Loan, effectively replacing both existing interest rate swaps. As a result, the Company has swapped $1.95 billion of notional value receiving interest at one month LIBOR plus 175 basis points for a fixed rate of 3.78% per annum settled monthly through the maturity date of the 2018 Term Loan. For further discussion of the Company’s interest rate swaps, refer to Note 1 and Note 22.

Secured Tower Revenue Securities

Tower Revenue Securities Terms

The mortgage loan underlying the 2013-2C Tower Securities, 2014-2C Tower Securities, 2015-1C Tower Securities, 2016-1C Tower Securities, 2017-1C Tower Securities, 2018-1C Tower Securities, and 2019-1C Tower Securities (together the “Tower Securities”) will be paid from the operating cash flows from the aggregate 10,043 tower sites owned by the Borrowers. The sole asset of the Trust consists of a non-recourse mortgage loan made in favor of those entities that are borrowers on the mortgage loan (the “Borrowers”). The mortgage loan is secured by (1) mortgages, deeds of trust, and deeds to secure debt on a substantial portion of the tower sites, (2) a security interest in the tower sites and substantially all of the Borrowers’ personal property and fixtures, (3) the Borrowers’ rights under certain tenant leases, and (4) all of the proceeds of the foregoing. For each calendar month, SBA Network Management, Inc., an indirect subsidiary (“Network Management”), is entitled to receive a management fee equal to 4.5% of the Borrowers’ operating revenues for the immediately preceding calendar month.

The Borrowers may prepay any of the mortgage loan components, in whole or in part, with no prepayment consideration, (1) within twelve months (in the case of the component corresponding to the Secured Tower Revenue Securities Series 2015-1C, Secured Tower Revenue Securities Series 2016-1C, Secured Tower Revenue Securities Series 2017-1C, Secured Tower Revenue Securities Series 2018-1C, and Secured Tower Revenue Securities Series 2019-1C) or eighteen months (in the case of the components corresponding to the Secured Tower Revenue Securities Series 2013-2C and Secured Tower Revenue Securities Series 2014-2C) of the anticipated repayment date of such mortgage loan component, (2) with proceeds received as a result of any condemnation or casualty of any tower owned by the Borrowers or (3) during an amortization period. In all other circumstances, the Borrowers may prepay the mortgage loan, in whole or in part, upon payment of the applicable prepayment consideration. The prepayment

consideration is determined based on the class of the Tower Securities to which the prepaid mortgage loan component corresponds and consists of an amount equal to the excess, if any, of (1) the present value associated with the portion of the principal balance being prepaid, calculated in accordance with the formula set forth in the mortgage loan agreement, on the date of prepayment of all future installments of principal and interest required to be paid from the date of prepayment to and including the first due date within twelve months (in the case of the component corresponding to the Secured Tower Revenue Securities Series 2015-1C, Secured Tower Revenue Securities Series 2016-1C, Secured Tower Revenue Securities Series 2017-1C, Secured Tower Revenue Securities Series 2018-1C, and Secured Tower Revenue Securities Series 2019-1C) or eighteen months (in the case of the components corresponding to the Secured Tower Revenue Securities Series 2013-2C and Secured Tower Revenue Securities Series 2014-2C) of the anticipated repayment date of such mortgage loan component over (2) that portion of the principal balance of such class prepaid on the date of such prepayment.

To the extent that the mortgage loan components corresponding to the Tower Securities are not fully repaid by their respective anticipated repayment dates, the interest rate of each such component will increase by the greater of (1) 5% and (2) the amount, if any, by which the sum of (x) the 10 year U.S. treasury rate plus (y) the credit-based spread for such component (as set forth in the mortgage loan agreement) plus (z) 5%, exceeds the original interest rate for such component.

Pursuant to the terms of the Tower Securities, all rents and other sums due on any of the towers owned by the Borrowers are directly deposited by the lessees into a controlled deposit account and are held by the indenture trustee. The monies held by the indenture trustee after the release date are classified as short-term restricted cash on the Consolidated Balance Sheets (see Note 4). However, if the Debt Service Coverage Ratio, defined as the net cash flow (as defined in the mortgage loan agreement) divided by the amount of interest on the mortgage loan, servicing fees and trustee fees that the Borrowers are required to pay over the succeeding twelve months, as of the end of any calendar quarter, falls to 1.30x or lower, then all cash flow in excess of amounts required to make debt service payments, to fund required reserves, to pay management fees and budgeted operating expenses and to make other payments required under the loan documents, referred to as “excess cash flow,” will be deposited into a reserve account instead of being released to the Borrowers. The funds in the reserve account will not be released to the Borrowers unless the Debt Service Coverage Ratio exceeds 1.30x for two consecutive calendar quarters. If the Debt Service Coverage Ratio falls below 1.15x as of the end of any calendar quarter, then an “amortization period” will commence and all funds on deposit in the reserve account will be applied to prepay the mortgage loan until such time that the Debt Service Coverage Ratio exceeds 1.15x for a calendar quarter. In addition, if any of the Tower Securities are not fully repaid by their respective anticipated repayment dates, the cash flow from the towers owned by the Borrowers will be trapped by the trustee for the Tower Securities and applied first to repay the interest, at the original interest rates, on the mortgage loan components underlying the Tower Securities, second to fund all reserve accounts and operating expenses associated with those towers, third to pay the management fees due to Network Management, fourth to repay principal of the Tower Securities and fifth to repay the additional interest discussed above. Furthermore, the advance rents reserve requirement states that the Borrowers are required to maintain an advance rents reserve at any time the monthly tenant Debt Service Coverage Ratio is equal to or less than 2:1 and for two calendar months after such coverage ratio again exceeds 2:1. The mortgage loan agreement, as amended, also includes covenants customary for mortgage loans subject to rated securitizations. Among other things, the Borrowers are prohibited from incurring other indebtedness for borrowed money or further encumbering their assets.
