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 ▇▇. ▇▇▇▇▇▇▇, 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:

Page 32

Reorganization or an order approving the Plan of Reorganization null or void, (iii) by Oncor Holdings, if the Board of Directors of Oncor Holdings determines in good faith after consultation with its outside financial advisors and outside legal counsel, and based on the advice of such counsel, that proceeding with this Letter Agreement would be inconsistent with its applicable fiduciary duties or (iv) by Oncor, if the Board of Directors of Oncor determines in good faith after consultation with its outside financial advisors and outside legal counsel, and based on the advice of such counsel, that proceeding with this Letter Agreement would be inconsistent with its applicable fiduciary duties.

The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Letter Agreement were not performed in accordance with their specific terms or were otherwise breached. Accordingly, each of the parties shall be entitled to specific performance and injunctive relief (but not any other form of equitable relief) to prevent or remedy breaches of this Letter Agreement, without the proof of irreparable damage or any actual damages or losses whatsoever. Without limiting the foregoing, the parties hereto agree that a party hereto may not assert that another party to this Letter Agreement is in breach of this Letter Agreement unless such non-breaching party provides the purported breaching party with written notice of such allegation within five (5) Business Days of the non-breaching party or its Affiliates first becoming aware of such purported breach. Prior to the non-breaching party seeking an injunction pursuant to this Section 17(k), the purported breaching party shall have five (5) Business Days after receiving such notice to cure any such breach. Within that five (5) Business Day period, the parties to this Letter Agreement also agree that senior management-level designees of each party shall meet and confer in an attempt to resolve any claim of a breach. Each party irrevocably agrees to waive any requirement for the security or posting of any bond in connection with such specific performance or injunctive relief.

Each party also agrees that in the event that Parent or Merger Sub asserts any claim against the Oncor Entities or their Representatives based upon or reflecting in any manner any provisions of the Merger Agreement and/or related documents, such claim, if any will be subject to and limited by this Section 17(k). Notwithstanding anything to the contrary in this Letter Agreement, in no event shall any party hereto or their Representatives be liable to any other party hereunder for any punitive, incidental, consequential, special or indirect damages, including loss of future revenue or income or opportunity, relating to the breach or alleged breach of this Letter Agreement.

IPO Corp will acquire a 100% controlling interest, and a minority economic interest, in the Merger Sub, thereby indirectly owning a minority economic interest in Oncor.

Parent intends to cause IPO Corp to conduct an initial public offering (“IPO”) of a class of securities of IPO Corp (“IPO Securities”), which will represent a minority of the voting interests in IPO Corp and an indirect minority economic interest in Oncor. Assuming no exercise of the TTI Conversion (defined below), immediately after the IPO, Parent, either directly or indirectly through Affiliate(s), will own the remainder of the voting interests and none of the economic interests in IPO Corp.

Pursuant to the Investor Rights Agreement, TTI will have the right to transfer all or a portion of its LLC Units (as such term is defined in the Investor Rights Agreement) in Oncor for securities of IPO Corp to reflect its proportionate economic and voting rights in Oncor (the “TTI Conversion”).

Parent will have right to exchange interests in Merger Sub for securities of IPO Corp, including IPO Securities.

Notwithstanding the IPO and/or the TTI Conversion, Parent will have control of IPO Corp and Merger Sub, either directly or indirectly through Affiliate(s).

Exhibit C

Key Regulatory Terms

This Exhibit C sets forth certain key terms and undertakings to be included in the PUCT Filing in connection with the PUCT Approval and, to the extent applicable, filings with other Governmental Entities in connection with the Purchase Transactions (“Regulatory Filings”).

The specific terms and undertakings to be included in the Regulatory Filings have not yet been determined and will depend on discussions among the parties and with the rating agencies and the regulatory authorities. In general, however, the Regulatory Filings would contain at least the following proposed commitments.

Parent commits that:

1.	Existing EFH/EFIH Legacy Debt - it will extinguish all debt that resides above Oncor at EFIH and EFH, reducing it to zero, immediately following the Closing.

New Debt Solely Dependent on Oncor - it and its subsidiaries, other than Oncor, will not incur, guarantee, or pledge assets in respect of any new debt that is solely or almost entirely dependent on the revenues of Oncor without first seeking PUCT approval. Parent and its Affiliates (other than Oncor) will provide advance notice to potential lenders of new debt issued pursuant to the PUCT approval received under this commitment of its corporate separateness from Oncor and will obtain an acknowledgement of the separateness and non-petition covenants in all such new debt instruments.

Credit Rating - the current credit issuer/corporate ratings of Oncor will be maintained or improved at the time of Closing. If, at any time from the date of closing through December 31, 2020, Oncor’s issuer/corporate rating is not maintained as investment grade by Standard & Poor’s, ▇▇▇▇▇’▇, or Fitch credit ratings agencies, Oncor shall not use the lower credit rating as a justification for a higher regulatory rate of return.

Reliability - for a period of five (5) years, for purposes of Substantive Rule 25.52, system average interruption duration index (“SAIDI”) and system average interruption frequency index (“▇▇▇▇▇”) standards should be calculated based on Oncor’s forced interruption performance for years 2011, 2013, and 2014. Oncor’s SAIDI standard should be 96.30667 and its ▇▇▇▇▇ standard should be 0.94000.

5.	Interconnection Process - Oncor will continue to participate in discussions with PUCT staff and customers to address implementing improvements to its interconnection process.

6.	Headquarters/Management - Oncor will maintain headquarters and management in Dallas County, Texas.

Capital Expenditures - Oncor will fund capital expenditures in the amounts set forth in Oncor’s current long range plan for five (5) years following the date of the closing. Notwithstanding the preceding sentence, Oncor may reduce capital spending due to conditions not under its control, including, without limitations, siting delays, cancellations of projects by third parties, or weaker than expected economic conditions as long as such conditions are reported to the PUCT in Oncor’s annual earnings monitoring report.

8.	Non-ERCOT Assets – Oncor and Oncor Holdings will not own, operate or construct capital assets outside of ERCOT without prior approval from the PUCT.

9.	Advisory Board - it will establish an advisory board of Texas residents that will meet quarterly with the Chief Executive Officer of Oncor to discuss service and other operational issues.

10.	Oncor Board of Directors - Parent will maintain a separate Board of Directors at Oncor.

11.

Debt-to-Equity Ratio - Oncor’s debt will be limited so that its regulatory debt-to-equity ratio (as determined by the PUCT) is at or below the assumed debt-to-equity ratio established from time to time by the PUCT for ratemaking purposes, which is currently set at 60% debt to 40% equity. The calculations of the debt-to-equity ratio for purposes of this commitment will not include goodwill resulting from the Merger.

12.	Rate Settlements - Oncor will comply with all terms and conditions imposed by Oncor’s previous rate settlements.

13.	Rate Case - Oncor will file a general base rate case by July 1, 2017, unless before that date a general base rate case has been initiated by Commission Staff or some other party.

14.

Workforce - for two years after closing, each current Oncor employee who is employed on the Closing Date, other than those executives identified in 17 below who choose to retire from or terminate their service with the Oncor Entities in connection with the Merger, will be provided (i) a base salary or wage rate that is no less favorable than the base salary or wage rate provided to such employee immediately prior to the Effective Time, (ii) aggregate incentive compensation opportunities that are substantially comparable in the aggregate to those provided to such employee immediately prior to the Effective Time, and (iii) employee benefits that are substantially comparable in the aggregate to those provided to such employee immediately prior to the Effective Time, and Oncor will not implement any material involuntary workforce reductions (with respect to either field or corporate personnel) of Oncor employees.

15.

Collective Bargaining Agreement - with respect to any Oncor employee whose terms and conditions of employment are covered by a collective bargaining agreement, the terms and conditions of such employment will continue to be governed by the terms of the applicable collective bargaining agreement, as may be modified from time to time.

16.	Employment Agreements - Oncor will honor any employment, severance, retention, termination, and change in control arrangements of Oncor in accordance with their terms.

17.

Change in Control - Each party hereto hereby acknowledges that, with respect to specified executives of the Oncor Entities, a “change in control” or “change of control” within the meaning of each Assumed Plan in which such employee is a participant or to which such employee is a party will occur as a result of the consummation of the Merger. For those specified executives who choose to retire from or terminate his or her service with the Oncor Entities in connection with the closing of the Merger, Parent and Merger Sub agree to pay any and all benefits (including change in control benefits) to which such individual would be entitled in connection with such retirement or termination, treating such retirement or termination as a resignation with “good reason,” a termination “without cause,” or a retirement under the relevant Assumed Plans.

18.	Benefits - for Oncor employees who become participants in any employee benefit plan of Parent or its Affiliates in connection with the Merger, the prior service of those employees to an Oncor entity will generally be taken into account, for purposes of eligibility and vesting thereunder.

19.

Code of Conduct - Oncor will comply with applicable laws and rules concerning affiliate activities and will file a revised Code of Conduct that will acknowledge that, for purposes of Oncor’s Code of Conduct, Gexa, certain NextEra Energy Resources subsidiaries and any other Parent Affiliates will be considered Texas competitive affiliates to the extent they provide services or sell products in a competitive energy-related market in Texas.

20.	Transaction Costs - none of the fees and expenses of the Merger will be borne by Oncor’s customers. Oncor further commits that it will not seek to include costs of the Merger in its rates.

21.	Pledging of Assets - Oncor will not incur, guaranty, or pledge assets in respect of any incremental new debt related to the Merger at the closing or thereafter. Oncor’s assets shall not be pledged for any entity other than Oncor.

22.

Goodwill - any costs of goodwill of Parent or its Affiliates (including Oncor) will not be included in rate base, cost of capital, or operating expenses in future ratemaking Oncor related proceedings. Write-downs or write-offs of goodwill will not be included in the calculation of net income for dividend payment purposes.

23.	Inter-company Debt - Oncor will not enter into any inter-company debt transactions with Affiliates of Parent following consummation of the Merger and Oncor will not lend money to or borrow money from Parent or its Affiliates.

24.

Separate Books and Records - Oncor will maintain accurate, appropriate, and detailed books, financial records and accounts, including checking and other bank accounts, and custodial and other securities safekeeping accounts that are separate and distinct from those of Parent and its other Affiliates.

25.	Shared Credit Facilities - Oncor will not share any credit facility with Parent or its Affiliates.

26.	Organizational Documents - the organizational documents of Oncor and any modifications to those documents will not be inconsistent with any order approving the Merger.

27.	Regulatory Modifications - until the Merger closes, Parent and Oncor agree to request approval from the PUCT of any modifications or additions to the approved commitments in this case by other regulatory bodies.

28.

Compliance Reports - for five (5) years post-closing, Oncor will file periodic reports with the PUCT regarding compliance with these commitments. Such reports will be filed at the same time as the annual earnings report under 16 Texas Administrative Code § 25.73 is filed for Oncor. All unexpired commitments will remain in effect after the end of the five-year reporting period and will expire according to their own terms.

29.

Dividends - Oncor shall not make any distributions, dividends, or other payments to Parent or its Affiliates without the prior approval of the PUCT at any time that two or more of Standard & Poor’s, ▇▇▇▇▇’▇, or Fitch credit rating agencies determine that Oncor’s issuer/corporate credit rating is not investment grade.

30.	Separate Name - Oncor shall maintain a name and logo separate and distinct from the names of its competitive Texas affiliates.

31.	No Recovery of Gexa Bad Debt - So long as Oncor is affiliated with Gexa, Oncor will not seek to recover from its customers any costs incurred as a result of a bankruptcy of Gexa.

32.	Bankruptcy Expense - Oncor will not seek recovery in rates of any expenses related to EFH’s bankruptcy.
