As described in the Registration Statement, the New 2021 Notes, New 2023 Notes, New 2024 Notes and the related Guarantees will be exchanged for the Company’s outstanding restricted 7.250% notes due 2021 (the “Old 2021 Notes”), the Company’s outstanding restricted 7.875% notes due 2023 (the “Old 2023 Notes”), the Company’s outstanding restricted 7.125% notes due 2024 (the “Old 2024 Notes”) and related guarantees, respectively. The Company will issue the New 2021 Notes pursuant to an indenture dated as of September 11, 2013 (the “Base Indenture”), by and between the Company and The Bank of New York Mellon Trust Company, N.A., as indenture trustee (the “Indenture Trustee”), as supplemented by the first supplemental indenture, dated as of September 11, 2013, by and among the Company, the Guarantor and the Indenture Trustee (the “2021 Notes Indenture”). The Company will issue the New 2023 Notes pursuant to the Base Indenture, as supplemented by the second supplemental indenture, dated as of September 11, 2013, by and among the Company, the Guarantor and the Indenture Trustee (the “2023 Notes Indenture”). The Company will issue the New 2024 Notes pursuant to the Base Indenture, as supplemented by the third supplemental indenture, dated as of December 12, 2013, by and among the Company, the Guarantor and the Indenture Trustee (the “2024 Notes Indenture”).
