On December 18, 2013, Time Warner Inc. (“Time Warner”) amended its $2.5 billion senior unsecured revolving credit facility with a maturity date of September 27, 2016 (the “Tranche One Facility”) and its $2.5 billion senior unsecured revolving credit facility with a maturity date of December 14, 2017 (the “Tranche Two Facility”) to, among other things, extend the maturity dates of both revolving credit facilities to December 18, 2018. The amendment also provides for up to two additional one-year extensions of the maturity dates for each revolving credit facility with lender consent. As amended, the interest rate on borrowings and the facility fee for both the Tranche One Facility and the Tranche Two Facility are the same and are based on the credit rating for Time Warner’s senior unsecured debt. Based on the credit rating as of December 18, 2013, the interest rate on borrowings under each revolving credit facility would be LIBOR (TIBOR in the case of yen borrowings) plus 1.100% per year and the facility fee is 0.150% per year. As of December 18, 2013, there were no borrowings outstanding under the revolving credit facilities.

The amendments were made pursuant to an Amendment and Restatement Agreement, dated as of December 18, 2013 (the “Amendment and Restatement Agreement”), relating to the Credit Agreement, dated as of January 19, 2011, as amended and restated as of December 14, 2012, among Time Warner and Time Warner International Finance Limited, as borrowers, the lenders from time to time party thereto and Citibank, N.A., as administrative agent (the “Credit Agreement”). The Amendment and Restatement Agreement amended and restated the Credit Agreement (as amended and restated, the “Amended and Restated Credit Agreement”) to reflect the changes described above.

The foregoing description of the Amendment and Restatement Agreement and the Amended and Restated Credit Agreement do not purport to be complete and are qualified in their entirety by reference to the Amendment and Restatement Agreement and the Amended and Restated Credit Agreement, which are filed as Exhibits 10.1 and 10.2, respectively, to this Current Report on Form 8-K.
