We understand that the Exchange Notes will represent the same debt as the Old Notes and the Parent will issue the Exchange Notes under the same Indenture (as amended, supplemented or otherwise modified through the date hereof, the “Indenture”), dated September 21, 2017, by and among the Parent, the Subsidiary Guarantors party thereto and U.S. Bank National Association, as trustee.
