Item 2.03. Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

Unitymedia Hessen GmbH & Co. KG (the “Original Borrower”) as original borrower, the other guarantors named therein (the “Guarantors”), The Bank of Nova Scotia as facility agent (the “Facility Agent”) and Credit Suisse AG, London Branch as security trustee (the “Security Trustee”), among others, are parties to a Senior Facilities Agreement, originally dated July 25, 2014 (as amended from time to time prior to the date of the Senior Facilities Agreement Amendment and Restatement Agreement (as defined below), the “Senior Facilities Agreement”) and a Super Senior Facilities Agreement, originally dated July 25, 2014 (as amended from time to time prior to the date of the Super Senior Facilities Agreement Amendment and Restatement Agreement as defined below), the “Super Senior Facilities Agreement”, together with the Senior Facilities Agreement, the “Facilities Agreements”). The Original Borrower and the Guarantors are each an indirect wholly-owned subsidiary of Liberty Global plc.

On June 19, 2017, the Original Borrower, the Guarantors, the Facility Agent and the Security Trustee entered into an amendment and restatement agreement (the “Senior Facilities Agreement Amendment and Restatement Agreement”), to amend and restate the Senior Facilities Agreement (the Senior Facilities Agreement, as amended and restated, the “Amended Senior Facilities Agreement”) and an amendment and restatement agreement (the “Super Senior Facilities Agreement Amendment and Restatement Agreement”, together with the Senior Facilities Agreement Amendment and Restatement Agreement, the “Amendment and Restatement Agreements”), to amend and restate the Super Senior Facilities Agreement (the Super Senior Facilities Agreement, as amended and restated, the “Amended Super Senior Facilities Agreement”, together with the Amended Senior Facilities Agreement, the “Amended Facilities Agreements”).

Each of the Amendment and Restatement Agreements amends and restates in full the applicable Facilities Agreement to, among other things, widen the scope of certain exceptions to the negative covenants, revise the change-of-control provision to allow for certain internal restructurings, amend certain default provisions and make administrative and consequential changes. Each of the Amended Facilities Agreements provides for the future incurrence of additional credit facilities thereunder; however, no additional indebtedness was incurred in connection with the effectiveness of the Amended Facilities Agreements.

All other terms of each of the Facilities Agreements remain in full force and effect under the applicable Amended Facilities Agreement, and all loans and commitments outstanding under each of the Facilities Agreements continue to be outstanding under the applicable Amended Facilities Agreement.

The Senior Facilities Agreement Amendment and Restatement Agreement (including the Amended Senior Facilities Agreement scheduled thereto) is attached hereto as Exhibit 4.1 and is incorporated herein by reference. The Super Senior Facilities Agreement Amendment and Restatement Agreement (including the Amended Super Senior Facilities Agreement scheduled thereto) is attached hereto as Exhibit 4.2 and is incorporated herein by reference. The foregoing description of the Amended Senior Facilities Agreement is qualified in its entirety by reference to the full text thereof set forth in Exhibit 4.1. The foregoing description of the Amended Super Senior Facilities Agreement is qualified in its entirety by reference to the full text thereof set forth in Exhibit 4.2.
