Introductory Note

On April 29, 2014, Energy Future Holdings Corp. (“EFH Corp.”), Energy Future Intermediate Holding Company LLC (“EFIH”) and EFIH Finance Inc. and certain of EFH Corp.’s subsidiaries (collectively, such entities, the “EFH Debtors”) filed voluntary petitions for relief (the “Bankruptcy Filing”) under Chapter 11 of the United States Bankruptcy Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”). The cases pending in the Bankruptcy Court concerning the Bankruptcy Filing are referred to in this Current Report on Form 8-K as the “Chapter 11 Cases.” During the pendency of the Chapter 11 Cases, the EFH Debtors have operated their businesses as debtors-in-possession under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code. The EFH Debtors will emerge from the Chapter 11 Cases if, and when, a plan of reorganization with respect to the EFH Debtors receives the requisite approval from holders of claims against, or interests in, the EFH Debtors, the Bankruptcy Court enters an order confirming such plan of reorganization, and the conditions to the effectiveness of such plan of reorganization, as stated therein, are satisfied.

Item 1.01. Entry into a Material Definitive Agreement.

As previously disclosed, on June 19, 2014 EFIH and EFIH Finance (together, the “EFIH Debtors”) entered into a $5.4 billion Senior Secured, Superpriority Debtor-in-Possession Credit Agreement (as amended, the “EFIH DIP Credit Agreement”) with the lenders party thereto and Deutsche Bank AG New York Branch, as administrative and collateral agent (the “Agent”). The EFIH DIP Credit Agreement had an original maturity date of June 19, 2016 (as subsequently extended, the “Maturity Date”). Effective January 12, 2016, the EFIH Debtors extended the Maturity Date to December 19, 2016.

On October 20, 2016, the EFIH Debtors entered into an Extension and Increase Amendment (the “2016 EFIH DIP Amendment”) to the EFIH DIP Credit Agreement with the Agent and the lenders party thereto. Pursuant to the 2016 EFIH DIP Amendment, (a) the EFIH Debtors received additional term loan commitments in an aggregate principal amount of $75.0 million and (b) the Maturity Date was extended to the earliest to occur of (i) June 30, 2017 (subject to a six-month extension upon the payment of an extension fee and the satisfaction of certain conditions specified in the 2016 EFIH DIP Amendment), (ii) the effective date of any Reorganization Plan (as defined in the EFIH DIP Credit Agreement), (iii) the consummation of a sale of all or substantially all of the EFIH Debtors’ assets or stock under section 363 of the Bankruptcy Code and (iv) the acceleration of any loans under the EFIH DIP Credit Agreement or the termination of any then outstanding term loan commitments in accordance with the terms of the EFIH DIP Credit Agreement. The EFIH Debtors paid aggregate fees and expenses of approximately $9.7 million in connection with the entrance into the 2016 EFIH DIP Amendment.

The above description of the 2016 EFIH DIP Amendment is qualified in its entirety by reference to the 2016 EFIH DIP Amendment, which is attached hereto as Exhibit 10.1 and incorporated herein by reference.
