The terms of the Notes are governed by an Indenture, dated as of May 20, 2019 (the “Base Indenture”), by and between the Company and U.S. Bank Trust Company, National Association (f/k/a U.S. Bank National Association) (the “Trustee”), as further supplemented by the Eighth Supplemental Indenture with respect to the 2029 Notes, as further supplemented by the Ninth Supplemental Indenture with respect to the 2031 Notes and as further supplemented by the Tenth Supplemental Indenture with respect to the 2037 Notes, each dated as of the Closing Date (collectively, the “Supplemental Indentures”; the Supplemental Indentures collectively with the Base Indenture, the “Indenture”), by and between the Company and the Trustee. The 2029 Notes mature on August 14, 2029 and bear interest at a rate of 4.800% per year. Interest on the 2029 Notes is payable on February 14 and August 14 of each year, beginning on February 14, 2027. The 2031 Notes mature on August 14, 2031 and bear interest at a rate of 5.050% per year. Interest on the 2031 Notes is payable on February 14 and August 14 of each year, beginning on February 14, 2027. The 2037 Notes mature on March 14, 2037 and bear interest at a rate of 5.550% per year. Interest on the 2037 Notes is payable on March 14 and September 14 of each year, beginning on March 14, 2027. The Notes are the Company’s general unsecured senior obligations and are equal in right of payment with all of the Company’s other existing and future unsecured and unsubordinated indebtedness, including the Company’s credit facility and the Company’s 5.750% Senior Notes due 2026, the Company’s 3.600% Senior Notes due 2027, the Company’s 4.350% Senior Notes due 2028, the Company’s 3.900% Senior Notes due 2029, the Company’s 4.200% Senior Notes due 2030, the Company’s 1.750% Senior Notes due 2031, the Company’s 4.700% Senior Notes due 2032 (such series of notes, collectively, the “Existing Notes”), the Company’s 5.000% Senior Notes due 2034 and the Company’s 5.100% Senior Notes due 2036. The Notes are effectively junior to the Company’s future secured indebtedness, if any, to the extent of the value of the collateral securing such indebtedness.

The Company would be permitted to release any such future guarantee without the consent of holders of the Notes under the circumstances described in the Indenture.

The Indenture contains covenants that limit the ability of the Company and each of its subsidiaries, as applicable to, among other things: (i) create certain liens on its assets to secure certain debt; (ii) enter into certain sale and leaseback transactions; and (iii) in the case of the Company, merge or consolidate with another company or transfer all or substantially all of the Company’s property, in each case as set forth in the Indenture. These covenants are, however, subject to a number of important limitations and exceptions.

In the case of an event of default, other than a default under clause (v) above, the Trustee or the holders of at least 25% in aggregate principal amount of the applicable series of Notes then outstanding, by written notice to the Company (and to the Trustee if the notice is given by the holders of such Notes), may declare the principal of and accrued and unpaid interest, if any, on such Notes to be immediately due and payable. If an event of default under clause (v) above occurs, the principal of and accrued and unpaid interest, if any, on the applicable series of Notes will be immediately due and payable without any act on the part of the Trustee or holders of such Notes. The Trustee is also a lender under the Company’s credit facility, and an affiliate of the Trustee was an underwriter in the offering of the Notes.
