The Unregistered Notes have been and the Exchange Notes will be guaranteed (the “Guarantees”) on a full and unconditional basis by each of the guarantors listed in Schedule A hereto (the “Guarantors”).

We understand that the Company intends to offer to exchange the Unregistered Notes and the Guarantees for up to an equivalent principal amount of Exchange Notes and related Guarantees, pursuant to an exchange offer registered with the United States Securities and Exchange Commission (the “SEC”).

The Exchange Notes and related Guarantees will be issued pursuant to an indenture (the “Indenture”) dated as of June 30, 2014 among the Company, Wilmington Trust, National Association, as trustee (the “Trustee”) and Citibank, N.A., as paying agent, registrar and authenticating agent (the “Securities Administrator”), as supplemented by a fourth supplemental indenture among the Company, the Guarantors, the Securities Administrator and the Trustee (including the Guarantees contained therein) dated as of December 4, 2017 (the “Supplemental Indenture”).
