Re: Oncor Letter Agreement

Ladies and Gentlemen:

Reference is made to that certain Agreement and Plan of Merger, dated as of July 29, 2016 (the “Merger Agreement”), by and among (i) Energy Future Holdings Corp., a Texas corporation (the “Company”), (ii) Energy Future Intermediate Holding Company LLC, a Delaware limited liability company (“EFIH” and, together with the Company, the “Sellers”), (iii) NextEra Energy, Inc., a Florida corporation (“Parent”), and (iv) EFH Merger Co., LLC, a Delaware limited liability company (“Merger Sub” and, together with Parent, the “Purchasers”), which agreement has been approved by the board of directors of the Company, the board of managers of EFIH and the board of directors of Parent and the manager of Merger Sub and will be submitted for approval by the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”). In addition, reference is made to the amended Plan of Reorganization (the “Plan of Reorganization”) attached to the Merger Agreement and filed or to be filed with the Bankruptcy Court on or about the date hereof by Parent, the Company, EFIH and other Debtors (as defined below) in connection with the Chapter 11 Cases (as defined below), which, among other things, provided for the transactions contemplated by the Merger Agreement. Upon the terms and conditions of the Merger Agreement, among other things, the Purchasers plan to acquire, pursuant to certain transactions described therein (the “Purchase”), direct or indirect equity interests in the Company and EFIH that indirectly represent all of the outstanding equity interests in Oncor Electric Delivery Holdings Company LLC (“Oncor Holdings”) and at least 80.03% of the outstanding equity interests in Oncor Electric Delivery Company LLC (“Oncor” and, together with Oncor Holdings and their respective Subsidiaries, the “Oncor Entities”). A full and complete copy of the Merger Agreement (including the Plan of Reorganization, which is attached as an exhibit thereto) has been provided to Oncor Holdings and Oncor.

WHEREAS, the Oncor Entities are “ring-fenced” from the Sellers and their Affiliates (as defined below), as a result of which, among other things, (i) the boards of directors of Oncor Holdings and Oncor are comprised of a majority of independent directors and (ii) certain arrangements are in place to maintain the separateness of the business and operations of the Sellers from the business and operations of the Oncor Entities (such limitations collectively, the “Ring-Fence”);

WHEREAS, in furtherance of the Purchase and in light of the Ring-Fence, the Order on Rehearing entered in PUCT Docket No. 34077, the limited liability company agreements (as amended) of Oncor Holdings and Oncor (the “LLC Agreements”), the 2007 Separation Agreement (as defined below) and the Investor Rights Agreement (as defined below), the Sellers have requested that Oncor Holdings and Oncor enter into this letter agreement (this “Letter Agreement”) and have provided their prior written consent, as the sole shareholder of Oncor Holdings (in the case of EFIH) and as the direct or indirect 80.03% equity interest holders of Oncor, and if the Merger Agreement or the Purchase Transactions (defined below) are designated as a conflict matter by the board of directors of EFIH, the consent of Mr. Cremens, the director on the EFIH board of directors appointed in the Bankruptcy Court to consider on behalf of EFIH matters as to which a conflict may exist with EFH and/or its other affiliates (the “EFIH Disinterested Director”), to Oncor Holdings and Oncor with respect to their entry into and performance of this Letter Agreement;

WHEREAS, this Letter Agreement sets forth certain rights and obligations of the Oncor Entities and the Purchasers to cooperate in the manner set forth herein with respect to initial steps to be taken in connection with the Merger and the IPO Conversion Plan (the “Purchase Transactions”);

WHEREAS, this Letter Agreement is not intended to give either Purchaser, directly or indirectly, the right to control or direct the operations of any Oncor Entity prior to the receipt of all approvals required by the Bankruptcy Court, the PUCT (as defined below) and other Governmental Entities (as defined below) and the consummation of the Purchase Transactions (if and when such transactions are consummated);

WHEREAS, Oncor Holdings and Oncor (i) have not endorsed or approved the IPO Conversion Plan (as defined below) or the other transactions proposed by the Purchasers and (ii) are not parties to the Merger Agreement and have not approved and are not required to approve the Merger Agreement;

WHEREAS, Purchasers will be the primary advocates in the PUCT on their proposal to acquire Oncor and Oncor Holdings, and Oncor Holdings and Oncor have agreed to use reasonable best efforts to make a single filing by the parties seeking prior approval by the PUCT of the Purchase Transactions; and have also agreed to allow Parent, subject to the terms of this Letter Agreement, to lead the PUCT approval process, in close cooperation with Oncor.

Page 2

WHEREAS, Oncor Holdings and Oncor have agreed to certain narrowly-defined limitations set forth herein with respect to their operations in the ordinary course of business from and after the date the Bankruptcy Court has entered an order approving the Merger Agreement (such date, the “Approval Date”) and prior to the Purchase Closing Date (as defined below), and they have preserved the right to take reasonable actions consistent with prudent industry practices to respond to emergency situations and/or to comply and respond to any requirement, or reasonable request, in a Governmental Request or Order (as defined below); and

WHEREAS, in exchange for the agreements of Oncor Holdings and Oncor in this Letter Agreement, Purchasers have agreed to certain commitments set forth herein with respect to the implications of the Purchase Transaction for Oncor Holdings, Oncor and their employees;

NOW, THEREFORE, in consideration of the premises, representations, warranties, covenants and agreements contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound, the parties hereto agree as follows:
