The Thirteenth Supplemental Indenture also provides for the guarantee of the TWCE Securities by CCO Holdings, LLC (“CCOH”), Charter Communications Operating, LLC and certain subsidiaries of Charter Communications Operating, LLC (“CCO”) (including subsidiaries of TWC) that are guarantors of CCO’s Amended and Restated Credit Agreement described below (the “Subsidiary Guarantors”).
