2

WHEREAS, Vistra Energy is currently the ultimate parent holding company of the Spin-Off Entities;

WHEREAS, pursuant to the TCEH Plan and as part of the EFH Contribution, the employees of EFH Corporate Services became the employees of Reorganized TCEH or one or more of its Subsidiaries;

The date on which the Closing actually occurs is hereinafter referred to as the “Closing Date.” For purposes of this Agreement, the term “Business Day” shall mean any day ending at 11:59 p.m. (Eastern Time) other than a Saturday or Sunday, or a day on which banks are required or authorized to close in New York, New York and the term “Person” shall mean any individual, corporation (including not-for-profit), general or limited partnership, limited liability company, joint venture, estate, trust, association, organization, Governmental Entity (as defined below) or other entity of any kind or nature. At the Closing, Parent, Merger Sub, reorganized EFIH, and the reorganized Company shall execute and deliver all certificates, instruments and documents required to be executed and/or delivered by such Person and/or any of its Affiliates (as defined below) under this Agreement in order for the conditions to the other party’s obligations to consummate the Closing to be satisfied.

Section 1.5Effective Time. On the terms and subject to the conditions set forth in this Agreement, on the Closing Date, the reorganized Company and Parent will cause certificates of merger to be executed, acknowledged and filed with the Secretary of State of the State of Delaware as provided under Section 252 of the DGCL and with the Secretary of State of the State of Texas as provided under Section 10.153 of the TBOC, as applicable (the “Certificates of Merger”), and shall take all such further actions as may be required by applicable Law to make the Merger effective. The Merger shall become effective as soon as reasonably practicable on the Closing Date (or at such other time as is mutually agreed to by the parties hereto in writing and specified in each of the Certificates of Merger) (such effective date and time, the “Effective Time”); and shall be immediately followed by the Accessible Account Deposit.

5

all of the property, rights, privileges, powers and franchises of the reorganized Company and Merger Sub shall vest in the Surviving Company, and all debts, liabilities and duties of the reorganized Company (to the extent not assumed by Reorganized TCEH or discharged under the Plan of Reorganization) and Merger Sub shall become the debts, liabilities and duties of the Surviving Company.

Section 1.7Accessible Account Deposit. At the Closing, (a) Parent shall cause Merger Sub to deliver the Cash Deposit Amount by wire transfer of immediately available funds to the EFH Plan Administrator Board (as defined in the Plan of Reorganization), (b) subject to Section 1.8, the Company will send any cash held by the Company as of the Closing Date, by wire transfer of immediately available funds, to the EFH/EFIH Cash Distribution Account, and (c) EFIH will send any cash held by EFIH as of the Closing Date, by wire transfer of immediately available funds, to the EFH/EFIH Cash Distribution Account (such deposits in clause (a), clause (b) and clause (c) herein, the “Accessible Account Deposit”); provided, however, that in no event shall cash held by the Company or EFIH to the extent comprising any dividend paid by Oncor in respect of earnings or income for any period from and after January 1, 2018 be sent to the EFH/EFIH Cash Contribution Account, but instead shall be retained by the Company and its Subsidiaries. The EFH Plan Administrator Board shall distribute the amounts from the Accessible Account Deposit in accordance with the Plan of Reorganization. For the avoidance of doubt, the EFH Plan Administrator Board shall be entitled to create such sub-accounts in the EFH/EFIH Cash Distribution Account as necessary to consummate the transactions contemplated by the Plan of Reorganization. “Cash Deposit Amount” shall mean $9,450,000,000, less the DIP Repayment; provided, that the Cash Deposit Amount shall be reduced in accordance with Section 1.8; provided, further, that (i) it is expected that Oncor will pay a dividend to Oncor Holdings and that Oncor Holdings will pay such dividend to EFIH in respect of amounts earned by Oncor during the period starting as of October 1, 2017 and ending on December 31, 2017 (such a dividend, a “2017 Dividend”), (ii) if the Closing occurs prior to the payment of such 2017 Dividend to EFIH, then the Cash Deposit Amount shall be increased by an amount equal to seventy-five percent (75%) of the actual 2017 Dividend (the “Payable Dividend Amount”), and the Surviving Company shall deliver, or cause to be delivered, such Payable Dividend Amount by wire transfer of immediately available funds to the EFH/EFIH Cash Distribution Account within five (5) Business Days following receipt by EFIH of such 2017 Dividend, and (iii) if the Closing occurs at any time following the payment of any 2017 Dividend, then the Cash Deposit Amount shall be reduced by an amount equal to twenty-five percent (25%) of the actual 2017 Dividend (the “Dividend Reduction Amount”). In no event shall the amount deposited by Merger Sub pursuant to Section 1.7(a), plus the DIP Repayment, plus the value of the Trust Certificates issued pursuant to Section 1.8 exceed $9,450,000,000, plus, if applicable, the Payable Dividend Amount, or minus if applicable, the Dividend Reduction Amount.

Section 1.8Adjustments for Equity Issuances.

(a)To the extent that the applicable Stakeholders elect (or are required), in accordance with the Plan of Reorganization, to receive equity in New HoldCo (as defined in the Plan of Reorganization) (“New HoldCo Equity Interests”) in lieu of cash for all or a portion of their respective EFH Consideration or EFIH Consideration, as applicable, then such Stakeholders shall be required to contribute such New HoldCo Equity Interests to the

6

Rollover Trust (as defined in the Plan of Reorganization) in return for Rollover Trust Certificates (as defined in the Plan of Reorganization) (“Trust Certificates”), and the Cash Deposit Amount shall, except to the extent otherwise provided in a Plan Supplement contemplated by Section 1.8(b), be reduced by an amount equal to the cash amount to which such Stakeholders would have otherwise been entitled absent such receipt of New HoldCo Equity Interests.

(b)In the event the Internal Revenue Service (the “IRS”) indicates that it will not provide one or more of the required Supplemental Rulings unless the consideration payable to the EFH Stakeholders (the “EFH Consideration”) in accordance with the Plan of Reorganization and/or the consideration payable to the EFIH Stakeholders in accordance with the Plan of Reorganization (the “EFIH Consideration”) includes some (or an additional) amount of New HoldCo Equity Interests, then (i) Parent shall cause New HoldCo Equity Interests, to the extent permitted by applicable Law, to be issued to certain Stakeholders pursuant to the Plan of Reorganization, in an amount sufficient to obtain the Supplemental Rulings, and (ii) such Stakeholders that receive such New HoldCo Equity Interests shall immediately thereafter contribute such New HoldCo Equity Interests to the Rollover Trust (as defined in the Plan of Reorganization) in return for Trust Certificates; provided, however, that in the event the IRS indicates that (a) the amount of New HoldCo Equity Interests necessary to obtain the Supplemental Rulings is in an amount greater than the difference between (x) $2,500,000,000 and (y) the value of Trust Certificates issued to Rollover Trust Participants (as defined in the Plan of Reorganization) (the “Maximum Required New HoldCo Issuance”), or (b) the granting of New HoldCo Equity Interests and the contribution of such New HoldCo Equity Interests to the Rollover Trust (as defined in the Plan of Reorganization) in exchange for Trust Certificates is insufficient to obtain one or more Supplemental Rulings, then the Company, EFIH (to the extent any such New HoldCo Equity Interests are anticipated to be issued to EFIH Stakeholders), Merger Sub and Parent shall cooperate, work and negotiate in good faith to identify an alternative structure or issue such other amount and/or form of equity consideration necessary to obtain the Supplemental Rulings; provided, however, the terms and conditions of such alternative structure, the amount of equity consideration, and/or the terms or conditions of such equity interest other than Trust Certificates shall be subject to the consent of Parent (such consent not to be unreasonably withheld, conditioned or delayed). Notwithstanding the foregoing, for purposes of the final proviso to the preceding sentence, for the avoidance of doubt it shall not be unreasonable for Parent to withhold its consent to a proposal or structure that would require it to issue or cause the issuance of (a) any common stock or preferred stock or other equity interests of Parent, (b) New HoldCo Equity Interests in an amount that exceeds the Maximum Required New HoldCo Issuance, or (c) New HoldCo Equity Interests with terms that are different than as set forth on Exhibit C. In all cases, the Company, EFIH, and Parent each understand that any issuance of equity (including New HoldCo Equity Interests) is not intended to increase or decrease the overall amount of consideration received by EFH Stakeholders or EFIH Stakeholders or the total amount of merger consideration payable by Parent (the “Value Condition”). To the extent New HoldCo Equity Interests must be issued pursuant to this paragraph, the mechanics implementing this paragraph shall be included in a Plan Supplement document that is reasonably acceptable to the Company, EFIH, Merger

7

Sub and Parent and the parties hereto shall take all steps necessary to effectuate the other transactions contemplated hereby.

required to be made by Parent or Merger Sub with, nor are any consents, registrations, approvals, permits or authorizations required to be obtained by Parent or Merger Sub from, the Bankruptcy Court or any other Governmental Entity in connection with the execution, delivery and performance of this Agreement by Parent and Merger Sub and the consummation by Parent and Merger Sub of the Closing Date Transactions and the other transactions contemplated by this Agreement, except those the failure of which to make or obtain has not had and would not have, individually or in the aggregate, a Parent Material Adverse Effect.

(ii)The execution, delivery and performance of this Agreement by Parent and Merger Sub does not, and the consummation by Parent and Merger Sub of the Merger and the other transactions contemplated by this Agreement will not, constitute or result in (A) a breach or violation of, or a default under, the certificate of incorporation, certificate of formation or bylaws or comparable governing documents of Parent or Merger Sub; (B) with or without notice, lapse of time or both, a breach or violation of, a termination (or right of termination) or a default under, the creation or acceleration of any obligations or the creation of a Lien on any of the assets of Parent or any of its Subsidiaries pursuant to, any Contracts binding upon Parent or any of its Subsidiaries or any Laws or governmental or non-governmental permit or license to which Parent or any of its Subsidiaries is subject; (C) any change in the rights or obligations of any party under any such Contracts; or (D) assuming compliance with the matters referred to in Section 5.2(d)(i), a violation of any Law to which Parent or any of its Subsidiaries is subject, except, in the case of clause (B), (C) or (D) above, for any breach, violation, termination, default, creation, acceleration or change that has not had and would not have, individually or in the aggregate, a Parent Material Adverse Effect.

(e)Parent Reports; Financial Statements.

(i)Parent has filed or furnished, as applicable, on a timely basis, all forms, statements, certifications, reports and other documents (including exhibits, financial statements and schedules thereto, and other information incorporated therein) required to be filed or furnished by it with the SEC pursuant to the Exchange Act or the Securities Act or any Contract governing any indebtedness of Parent requiring such filings to be made since the Applicable Date (the forms, statements, certifications, reports and documents filed or furnished since the Applicable Date and those filed or furnished subsequent to the date hereof, including any amendments thereto, the “Parent Reports”). Each of the Parent Reports, including any financial statements or schedules included therein, at the time of its filing or being furnished complied or, if not yet filed or furnished, will comply in all material respects with the requirements of the Securities Act, the Exchange Act and the Sarbanes-Oxley Act applicable to the Parent Reports. As of their respective dates (or, if amended prior to, or after, the date hereof, as of the date of such amendment), the Parent Reports filed with or furnished to the SEC prior to the date hereof did not, and any Parent Reports filed with or furnished to the SEC subsequent to the date hereof will

37

not, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements made therein, in light of the circumstances in which they were made, not misleading. There are no outstanding or unresolved comments received from the SEC staff with respect to the Parent Reports. None of the Parent Reports is, to the knowledge of Parent, the subject of ongoing SEC review.

(ii)Each of the consolidated balance sheets included in or incorporated by reference into the Parent Reports as amended prior to the date hereof (including the related notes and schedules) fairly presents in all material respects, or, in the case of Parent Reports filed after the date hereof, will fairly present in all material respects the financial position of Parent and its consolidated Subsidiaries as of its date (and if amended, as of the date of the last such amendment prior to the date hereof) and each of the statements of consolidated income, comprehensive income, cash flows and shareholders’ equity included in or incorporated by reference into the Parent Reports (including any related notes and schedules), as finally amended prior to the date hereof, fairly presents in all material respects, or in the case of Parent Reports filed after the date hereof, will fairly present in all material respects the financial position, results of operations and cash flows, as the case may be, of Parent and its consolidated Subsidiaries for the periods set forth therein (subject, in the case of unaudited statements, to notes and normal year-end adjustments), in each case in accordance with GAAP, except as may be noted therein.

(iii)Parent maintains internal control over financial reporting (as defined in Rule 13a-15 or 15d-15, as applicable, under the Exchange Act). Such internal control over financial reporting is effective in providing reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP, in each case, in all material respects. Except as has not had, or would not reasonably be expected to have, individually or in the aggregate, a material effect on the nature or reliability of the information disclosed in Parent’s periodic reports filed under the Exchange Act, (A) Parent maintains disclosure controls and procedures required by Rule 13a-15 or 15d-15 under the Exchange Act that are effective to ensure that information required to be disclosed by Parent is recorded and reported on a timely basis to the individuals responsible for the preparation of Parent’s filings with the SEC and other public disclosure documents (including Parent’s chief executive officer and chief financial officer) and (B) Parent has not disclosed, and is not required to disclose, based on its most recent evaluation prior to the date of this Agreement, to Parent’s outside auditors and the audit committee of Parent’s board of directors, and has not had, (1) any significant deficiencies and material weaknesses in the design or operation of internal controls over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that are reasonably likely to adversely affect Parent’s ability to record, process, summarize and report financial information in any material respect and (2) any fraud, known to Parent, whether or not material, that involves

38

management or other employees who have a significant role in Parent’s internal controls over financial reporting.

(iv)Except as has not had and would not have, individually or in the aggregate, a Parent Material Adverse Effect, each of Parent and its Subsidiaries is in compliance with the applicable provisions of the Sarbanes-Oxley Act. Without limiting the generality of the foregoing, neither Parent nor any of its Subsidiaries is a party to, or has a commitment to become a party to, any joint venture, off-balance sheet partnership or any similar Contract or arrangement (including any Contract or arrangement relating to any transaction or relationship between or among Parent or any of its Subsidiaries, on the one hand, and any unconsolidated Affiliate, including any structured finance, special purpose or limited purpose entity or Person, on the other hand) or any “off-balance sheet arrangements” (as defined in Item 303(a) of Regulation S-K of the SEC), where the result, purpose or effect of such Contract or arrangement is to avoid disclosure of any material transaction involving, or material liabilities of, Parent or any of its Subsidiaries in the Parent Reports or the financial statements included therein.

(f)Absence of Certain Changes. Since December 31, 2016, there has not occurred a Parent Material Adverse Effect. Neither Parent nor any of its Subsidiaries has any liabilities or obligations of any nature (whether accrued, absolute, contingent or otherwise), other than liabilities and obligations (A) set forth in Parent’s consolidated balance sheet as of December 31, 2016, including the notes thereto, included in the Company Reports, (B) incurred in the ordinary course of business consistent with past practice since December 31, 2016, (C) incurred in connection with the Closing Date Transactions or any other transaction or agreement contemplated by this Agreement, (D) pursuant to any Contract that would be required to be filed by Parent as a “material contract” (as such term is defined in item 601(b)(10) of Regulation S-K of the Securities Act, except for any such Contract that is a Benefit Plan) or that was or is material to the business, operations or financial condition of Parent and its Subsidiaries, taken as a whole (but not including any liability for breach thereunder), or (E) that has not had and would not have, individually or in the aggregate, have a Parent Material Adverse Effect.

For purposes of this Agreement “Parent Material Adverse Effect” means (i) any fact, event, change, effect, development, circumstance or occurrence that, individually or together with all other facts, events, changes, effects, developments, circumstances or occurrences, has had or would reasonably be expected to have a material and adverse effect on, or change in, the financial condition, business, assets, liabilities or results of operations of Parent and its Subsidiaries, taken as a whole, for the avoidance of doubt any reference in any provision hereof to any item that “would have a Parent Material Adverse Effect”, or any similar phrase, shall be interpreted as “individually or in the aggregate, has had or would be reasonably expected to have, a Parent Material Adverse Effect” (and such interpretation shall extend to the negative expression of such phrase, or any similar phrase, mutatis mutandis), or (ii) anything that prevents, materially restricts, or materially impairs Parent or Merger Sub from consummating the Closing Date Transactions; provided, however, that, none of the following

39

shall constitute or be taken into account in determining whether there has been or is a Parent Material Adverse Effect:

(i)(x) changes or developments in general economic or political conditions or the securities, credit or financial markets, in general, globally or outside of or in the U.S. or in the State of Texas or (y) changes that are the result of acts of war or terrorism or any hurricane, tornado, tsunami, flood, earthquake or other natural disaster or other weather-related event, circumstance or development (other than such acts of war or terrorism or any hurricane, tornado, tsunami, flood, earthquake or other natural disaster or other weather-related event, circumstance or development that cause any physical damage or destruction to or render physically or operationally unusable any facility or property of Parent, Merger Sub or any of their respective Subsidiaries);

(iv)changes or developments that are the result of factors generally affecting any industry in which Parent or its Subsidiaries operate;

(v)any loss or threatened loss of, or adverse change or threatened adverse change in, the relationship of Parent or any of its Subsidiaries with its customers, employees, regulators, financing sources or suppliers to the extent caused by the pendency or the announcement of the transactions contemplated by this Agreement or Plan of Reorganization;

(vi)changes, effects or developments to the extent relating to the entry into this Agreement, the performance of actions or obligations required to be taken by a party hereunder or consented to in writing by the Company and EFIH, including any change in Parent’s or any of its Subsidiaries’ credit ratings to the extent resulting therefrom;

(vii)changes or developments in GAAP or authoritative interpretation thereof after the date hereof; and

(viii)any failure by Parent or any of its Subsidiaries to meet any internal or public projections or forecasts or estimates of revenues or earnings for any period, in and of itself, provided that the exception in this clause shall not prevent or otherwise

40

affect a determination that any change, effect or development underlying such failure has resulted in, or contributed to, a Parent Material Adverse Effect;

provided, further, that (x) facts, events, changes, effects, developments, circumstances or occurrences set forth in clauses (i) through (iv) above may be taken into account in determining whether there has been or is a Parent Material Adverse Effect to the extent such matters, changes, effects or developments have a disproportionate and adverse effect on Parent and its Subsidiaries, taken as a whole, as compared to other entities engaged in the relevant business in Texas or other relevant geographic area and (y) any condition or requirement attached to any order or approval issued by the PUCT, FERC or FCC that is necessary or was sought in order to consummate the transactions contemplated by this Agreement, and/or the Plan of Reorganization shall not constitute, or be deemed to contribute to, a Parent Material Adverse Effect.

There are no civil, criminal or administrative actions, suits, complaints, enforcement actions, penalty assessments, claims, hearings, arbitrations, investigations, inquiries, audits or other proceedings (formal or informal, public or non-public) pending or, to the knowledge of Parent, threatened in writing against Parent or any of its Subsidiaries, in each case that, individually or in the aggregate, has had or would have a Parent Material Adverse Effect. None of Parent or any of its Subsidiaries is a party to or subject to the provisions of any judgment, settlement, order, writ, injunction, decree or award of any Governmental Entity specifically imposed upon Parent, any of its Subsidiaries or any of their respective businesses, assets or properties which, individually or in the aggregate, has had or would have a Parent Material Adverse Effect.

(iii)in the event that any permanent, preliminary or temporary injunction, decision, order, judgment, determination, decree or Law is entered, issued or enacted, or becomes reasonably foreseeable to be entered, issued or enacted, in any proceeding, review or inquiry of any kind that would make consummation of the transactions contemplated by this Agreement or the Plan of Reorganization unlawful or that would prevent, enjoin or otherwise prohibit, or materially impair, restrain or restrict, the transactions contemplated by this Agreement or the Plan of Reorganization, vacate, modify, reverse, suspend, prevent, eliminate, avoid, remove or comply with such actual, anticipated or threatened injunction, decision, order, judgment, determination, decree or enactment so as to permit prompt consummation of the transactions contemplated by this Agreement.

In the event that the Company or its Subsidiaries are required to agree to the sale, license, divestiture, hold separate or other disposition of any assets, categories of assets or businesses of the Company or any of its Subsidiaries in connection with obtaining a Company Approval, then such requirement may contribute to, or be, a Burdensome Condition.

Section 6.14Tax Matters.

(a)Private Letter Ruling. The Company, on behalf of the Debtors, has received a private letter ruling (the “Private Letter Ruling”) from the IRS in response to a written request, dated June 10, 2014 (the “Initial Ruling Request,” and together with all related materials and supplements thereto filed with respect to the Initial Ruling Request, the “Initial IRS Submissions”). The Private Letter Ruling addresses certain issues related to the qualification of the Reorganized TCEH Contributions, the Reorganized TCEH Conversion, and the Reorganized TCEH Spin-Off as a “reorganization” within the meaning of Sections 368(a)(1)(G), 355 and 356 of the Code (collectively, the “Intended Tax-Free Treatment”) and certain other matters. The parties hereto acknowledge and agree that the Private Letter Ruling is acceptable to the parties hereto with respect to the Intended Tax-Free Treatment. The transactions contemplated by this Agreement are not conditioned on the receipt of any additional rulings from the IRS, other than the Supplemental Rulings (defined below).

(b)Supplemental Ruling. The Company has prepared and filed with the IRS a supplemental ruling request, dated November 3, 2016, that, among other things, requests rulings that address the effect of the Company’s previously contemplated merger with a direct wholly owned subsidiary of NextEra Energy, Inc., a Florida Corporation, on certain of the rulings received in the Private Letter Ruling (the “Prior Supplemental Ruling Request”). The Company shall be responsible for the preparation and filing with the IRS of one or more supplemental ruling requests, whether in the form of modifying the Prior Supplement Ruling Request or in the form of a new request, that, among other things, request rulings that address the effect of the Merger on certain of the rulings received in the Private Letter Ruling as reflected on Exhibit E (such request, the “Supplemental Ruling Request,” the rulings to be granted pursuant thereto, the “Supplemental Rulings,” and the materials filed or to be filed in respect of the Supplemental Ruling Request, the “Supplemental IRS Submissions” and together with the Initial IRS Submissions, the “IRS Submissions”).

(c)Supplemental IRS Submissions. The Company shall be responsible for the preparation and filing of the Supplemental IRS Submissions. The Company shall provide tax counsel of Parent with a reasonable opportunity to review and comment on drafts of all such IRS Submissions and any pre-filing agreement or closing agreement that is intended to satisfy the requirements of Section 7.1(d) or that could reasonably be determined to affect the treatment of the restructuring transactions contemplated by this Agreement and the Plan of Reorganization to be submitted or entered into on or after the date hereof. The Company agrees to supplement or modify any Supplemental IRS Submissions and agreements related to Supplemental IRS Submissions as may be reasonably requested by Parent; provided, however, that the Company shall not be required to supplement or modify any Supplemental IRS Submission, request any additional ruling, or modify any ruling being requested with respect to the Supplemental Rulings (other than with respect to the effect of the Merger and the transactions contemplated by this Agreement) if the Company determines, in its reasonable discretion, that making such supplement, modification, or request could result in any delay in obtaining the Supplemental Rulings or be otherwise detrimental to the process of obtaining the Supplemental Rulings. The parties hereto

69

acknowledge and agree that it is anticipated that this Agreement and the facts related to the contemplated Merger will be disclosed to the IRS pursuant to a Supplemental IRS Submission. To the extent that the Company, in its good faith judgment, or upon a reasonable request by any other person, considers any information included in an IRS Submission or a Supplemental IRS Submission (or drafts thereof) to be confidential, the Company may redact such documents to exclude such information before providing such documents to Parent. Subject to the foregoing, the Company shall provide Parent with copies of each Supplemental IRS Submission promptly following the filing thereof.

(d)IRS Communications and Cooperation. The Company shall notify Parent of any substantive communications with the IRS regarding the Supplemental IRS Submissions and restructuring transactions contemplated by this Agreement and by the Plan of Reorganization. Notwithstanding the foregoing, a single Representative from Parent shall be given the opportunity to participate in all scheduled communications with the IRS concerning the Supplemental Ruling Requests or any restructuring transactions contemplated by this Agreement and by the Plan of Reorganization, including, (i) all scheduled conference calls that are expected to address material issues with respect to which there is sufficient prior notice and the IRS indicates its acceptance of multiple participants and (ii) all in-person meetings. The Company shall update Parent in a timely fashion regarding any unscheduled communications from the IRS or any other communication with respect to which a Representative of Parent does not participate. The Company and Parent agree to cooperate and use their reasonable best efforts to assist in obtaining the rulings requested in the Supplemental Ruling Requests (including, for the avoidance of doubt, the requested rulings, if any, that are not Supplemental Rulings described on Exhibit E), including providing such appropriate information and representations as the IRS shall reasonably require in connection with the Supplemental Rulings or any restructuring transactions contemplated by this Agreement and by the Plan of Reorganization. The Company and Parent agree to use their commercially reasonable efforts to provide any appropriate information and additional representations necessary or appropriate in connection with the Supplemental Rulings. The Company and Parent agree to use their commercially reasonable efforts to implement any changes to the restructuring transactions contemplated by this Agreement and by the Plan of Reorganization to the extent such changes would not, unless otherwise agreed by Parent, result in a material economic detriment to Parent or the Company or any of their respective Subsidiaries if requested by the IRS in order to issue reasonably satisfactory Supplemental Rulings;provided,however, that this sentence shall not apply to any changes to the restructuring transactions contemplated by this Agreement and by the Plan of Reorganization addressed bySection 1.8of this Agreement, with respect to which the terms ofSection 1.8of this Agreement shall govern.

(e)Tax Opinion. Prior to the Closing, the Company shall use its commercially reasonable efforts to obtain the tax opinion contemplated by Section 7.3(c), if applicable, and Parent shall use its commercially reasonable efforts to obtain the tax opinion contemplated by Section 7.2(e), if applicable.

70

(f)Tax Matters Agreement. Prior to the Closing, the Company shall not, without the prior written consent of Parent, (i) consent to any amendment to the Tax Matters Agreement or waive any of its or its Affiliates’ rights thereunder or (ii) take or fail to take any action that would constitute a breach of the Tax Matters Agreement.

(g)Supplemental E&P Ruling. Notwithstanding anything in this Agreement or the Tax Matters Agreement to the contrary, the Company shall, without further consent of Parent, be permitted, but not required, to file (or join or otherwise participate in a filing) a request for a supplemental ruling with the IRS that solely addresses the proper allocation of earnings and profits in connection with the Reorganized TCEH Spin-Off (the “E&P Allocation Ruling Request”). Parent shall have no consent or participation rights with respect to such E&P Allocation Ruling Request, provided, however, that the Company shall provide materials related to the E&P Allocation Ruling Request to Parent for review and comment, provided, further, that the Company shall not be required to accept any comments provided by Parent but shall consider any such comments in good faith. Notwithstanding the foregoing, Parent shall have the right to review, comment on and approve any items included in the E&P Allocation Ruling Request that do not solely address the proper allocation of earnings and profits in connection with the Reorganized TCEH Spin-Off. To the extent of any inconsistency between the Tax Matters Agreement and any ruling provided in response to the E&P Allocation Ruling Request, the E&P Allocation Ruling Request shall control, and Parent hereby consents to any modification that may be necessary to the Tax Matters Agreement in light of such ruling; provided, however, that any modification to the Tax Matters Agreement shall require Parent’s consent to the extent such modification does not solely relate to the proper allocation of earnings and profits in connection with the Reorganized TCEH Spin-Off.

(a)Bankruptcy Orders. The Bankruptcy Court shall have entered (in a form which is not materially inconsistent, in any substantive legal or economic respect, with the rights and obligations of the Company or EFIH or Parent or Merger Sub hereunder or in the Plan of Reorganization) (i) the order of the Bankruptcy Court approving this Agreement, including, among other things, approval of the Termination Fee and the Company’s and EFIH’s entry into and performance of their obligations under this Agreement and the related agreements (the “Approval Order”) and (ii) an order, in form reasonably satisfactory to

77

Parent, confirming the Plan of Reorganization with respect to the E-Side Debtors and authorizing all of the transactions and agreements contemplated by this Agreement (the “EFH Confirmation Order”), which in each case shall be in full force and not subject to any stay.

(b)Orders. No court or other Governmental Entity of competent jurisdiction shall have enacted, issued, promulgated, enforced or entered any Law or order (whether temporary, preliminary or permanent) that is in effect and restrains, enjoins, renders illegal or otherwise prohibits consummation of the Closing Date Transactions.

(c)Opinion of Counsel with respect to the Reorganized TCEH Spin-Off. The tax opinion of Kirkland & Ellis LLP obtained by the Company on October 3, 2016 to the effect that the Reorganized TCEH Contributions, Reorganized TCEH Conversion and Reorganized TCEH Spin-Off meet the requirements of Sections 368(a)(1)(G), 355 and 356 of the Code shall not have been revoked, rescinded or modified in any respect (except as consented to in writing by Parent).

The Private Letter Ruling shall remain in full force and effect and shall not have been revoked, withdrawn or amended and the Supplemental Rulings shall have been obtained by the Company from the IRS in a form reasonably satisfactory to Parent; provided, however, that (A) a particular ruling that, in the reasonable determination of Parent covers substantially the same subject matter as any one or more of the Supplemental Rulings set forth in Exhibit E shall not be grounds for concluding that the Supplemental Rulings (collectively) are not reasonably satisfactory to Parent due to its failure to include such ruling, (B) in the event a specific Supplemental Ruling set forth in Exhibit E is not given because the IRS communicates that there is no significant issue with respect to the requested ruling, the absence of such ruling shall not, standing alone (or collectively)

78

be grounds for concluding the Supplemental Rulings (collectively) are not reasonably satisfactory to Parent; provided that Parent, and unless waived by Parent, the Company, obtain an opinion of nationally recognized tax counsel, in form and substance acceptable to Parent, at a “will” level with respect to the issue that was initially requested pursuant to the Supplemental Ruling Request, or (C) a pre-filing agreement (including an agreement in accordance with Revenue Procedure 2016-30) or closing agreement with the IRS shall be acceptable in lieu of such specific Supplemental Ruling set forth in Exhibit E; provided that such agreement is both (i) binding on the IRS to the same degree as a private letter ruling or is otherwise acceptable to Parent in its reasonable discretion, and (ii) contains, in the reasonable determination of Parent conclusions that are substantially similar, and have substantially the same practical effect, to those contained in the specific rulings initially requested pursuant to the Supplemental Ruling Requests.

(iii)the Bankruptcy Court does not enter the Disclosure Statement Order by September 30, 2017; provided, that, entry of such order shall be deemed to occur upon an oral indication by the Bankruptcy Court that it is approving or will approve the Disclosure Statement and solicitation materials as containing “adequate information” as required by section 1125 of the Bankruptcy Code; or

(i)if Parent, Merger Sub, Oncor and Oncor Holdings fail to enter into the Oncor Letter Agreement within five (5) days following the date hereof; provided, however, that if Parent has not terminated this Agreement pursuant to this Section 8.4(i) within ten (10) days following the end of such five (5) day period, this Section 8.4(i) shall be of no further force and effect and Parent shall have no such right to terminate this Agreement.

(a)In the event of a termination of this Agreement pursuant to this Article VIII, this Agreement shall become void and of no further force or effect and no party shall have any liability to any other party hereto (or of any of its Representatives or Affiliates) with respect hereto; provided, however, and notwithstanding anything in the foregoing to the contrary, that, (i) this Section 8.5 and the provisions set forth in the second sentence of Section 9.1 shall survive the termination of this Agreement and the parties hereto may have further liability with respect thereto, and (ii) liability may exist for willful or intentional breaches of this Agreement (where willful or intentional breach means a breach of this Agreement by a party that has actual knowledge that its action (or failure to act) would reasonably be expected to breach this Agreement) by a party prior to the time of such termination and, in the case of Parent and Merger Sub, any failure to have sufficient immediately available funds at the Closing for the consummation of the Closing Date Transactions (which liability the parties hereto acknowledge and agree shall not be limited to reimbursement of expenses or out-of-pocket costs).

(b)If this Agreement is terminated pursuant to Section 8.3(e), Section 8.3(f), Section 8.4(a), Section 8.4(d) or Section 8.4(e), and any alternative transaction is consummated (including pursuant to any Chapter 7 proceedings or any transaction or proceeding that permits the E-Side Debtors that are the direct or indirect owners of Oncor Holdings to emerge from the Chapter 11 Cases) pursuant to which none of Parent, Merger Sub or any of their respective Affiliates will obtain direct or indirect ownership of 100% of Oncor Holdings and Oncor Holdings’ approximately 80% equity interest in Oncor, then, if the Approval Order has been entered, no later than five (5) days following the consummation of such alternative transaction, the Company and EFIH shall pay to Parent the Termination Fee (as defined below), by wire transfer, as directed by Parent, in immediately available funds. In the event the Company and EFIH pay the Termination Fee pursuant to this Section 8.5(b), such payment shall be the sole and exclusive remedy of Parent and Merger Sub against the Company, EFIH and their respective Affiliates, Representatives, creditors or shareholders with respect to any breach of this Agreement prior to such termination. If the Approval Order has been entered, the Company’s and EFIH’s obligation to pay the Termination Fee pursuant to this Section 8.5(b) shall survive the termination of this Agreement. If the Approval Order has been entered, the Termination Fee shall constitute an administrative expense of the Company and EFIH under the Bankruptcy Code. “Termination Fee” shall mean an amount equal to $190,000,000, inclusive of all expense reimbursements, including reasonable and documented professional fees of Parent and Merger Sub; provided that, in no event shall such claim be senior or pari passu with the superpriority administrative

88

claims granted to the secured parties pursuant to the DIP Facility (as in effect on the date hereof).

(c)The parties hereto acknowledge that the agreements contained in this Section 8.5 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the parties hereto would not enter into this Agreement.

Section 9.7Entire Agreement. This Agreement (including any exhibits or schedules hereto including as actually executed), the Company Disclosure Letter, the Oncor Letter Agreement, the Confidentiality Agreement, dated August 10, 2017, by and among Parent, the Company and EFIH (the “Confidentiality Agreement”) and the other agreements named herein constitute the entire agreement of the parties hereto with respect to the subject matter hereof, and cancel, merge and supersede all other prior or contemporaneous oral or written agreements, understandings, representations and warranties both written and oral, among the parties hereto, with respect to the subject matter hereof. EACH PARTY HERETO AGREES THAT, EXCEPT FOR THE REPRESENTATIONS AND WARRANTIES CONTAINED IN THIS AGREEMENT AND THE ONCOR LETTER AGREEMENT, NEITHER PARENT AND MERGER SUB NOR THE COMPANY AND ITS SUBSIDIARIES MAKES ANY OTHER REPRESENTATIONS OR WARRANTIES, AND EACH HEREBY DISCLAIMS ANY OTHER REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED, OR AS TO THE ACCURACY OR COMPLETENESS

92

OF ANY OTHER INFORMATION, MADE BY, OR MADE AVAILABLE BY, ITSELF OR ANY OF ITS REPRESENTATIVES, WITH RESPECT TO, OR IN CONNECTION WITH, THE NEGOTIATION, EXECUTION OR DELIVERY OF THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT, NOTWITHSTANDING THE DELIVERY OR DISCLOSURE TO THE OTHER OR THE OTHER’S REPRESENTATIVES OF ANY DOCUMENTATION OR OTHER INFORMATION WITH RESPECT TO ANY ONE OR MORE OF THE FOREGOING.

Section 9.8No Third-Party Beneficiaries. Except as provided in Section 6.8, Parent, Merger Sub, EFIH and the Company hereby agree that their respective representations, warranties and covenants set forth herein are solely for the benefit of the other parties hereto, in accordance with and subject to the terms of this Agreement, and this Agreement is not intended to, and does not, confer upon any Person other than the parties hereto any rights or remedies hereunder, including the right to rely upon the representations and warranties set forth herein, except for the rights of the Financing Sources pursuant to this Section 9.8, Section 9.2, Section 9.5 and Section 9.16 (who are intended third party beneficiaries thereunder and are intended to be the only third party beneficiaries thereunder). The parties hereto further agree that the rights of third party beneficiaries under Section 6.8 shall not arise unless and until the Effective Time occurs. The representations and warranties in this Agreement are the product of negotiations among the parties hereto and are for the sole benefit of the parties hereto. In some instances, the representations and warranties in this Agreement may represent an allocation among the parties hereto of risks associated with particular matters regardless of the knowledge of any of the parties hereto. Consequently, Persons other than the parties hereto may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.

Section 9.9Obligations of Parent. Whenever this Agreement requires a Subsidiary of Parent, including Merger Sub, to take any action, such requirement shall be deemed to include an undertaking on the part of Parent to cause such Subsidiary to take such action.

Section 9.10Remedies. The parties hereto agree that irreparable damage would occur in the event that any provision of this Agreement was not performed by the Company, EFIH, Parent or Merger Sub in accordance with the terms hereof and that monetary damages, even if available, would not be an adequate remedy therefor. As a result, prior to the termination of this Agreement pursuant to Article VIII, each party shall be entitled to specific performance to prevent breaches of this Agreement and of the terms hereof (including the obligation to consummate the Closing Date Transactions and the other transactions contemplated herein, subject to the terms and conditions hereof), without proof of actual damages (and each party hereby waives any requirement for the securing or posting of any bond in connection with such remedy) in addition to any other remedy at law or equity. The parties hereto further agree not to assert that a remedy of monetary damages would provide an adequate remedy for any such breach. The parties acknowledge the Company’s right to (i) seek specific performance and (ii) to cause Parent and Merger Sub to sue and enforce against the Financing Sources, but with respect to clause (ii), only to the extent Parent or Merger Sub have such a right under the Debt Commitment Letter.

93

Section 9.11Transfer Taxes.

Section 9.12Definitions. Each term set forth in the Table of Defined Terms is defined on the page of this Agreement set forth opposite such term.

Section 9.13Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule or Law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated by this Agreement is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in an acceptable manner to the end that the transactions contemplated by this Agreement are fulfilled to the extent possible.

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

WHEREAS, except as expressly set forth herein, this Letter Agreement is not intended to give any Purchaser, directly or indirectly, any right to control or to direct the operations or decisions of any Oncor Entity;

WHEREAS, Oncor Holdings and Oncor (i) have not endorsed or approved any transactions or commitments proposed by the Purchasers, (ii) are not parties to or bound by the Merger Agreement and (iii) have not approved and are not required to approve the Merger Agreement;

WHEREAS, Oncor and Purchasers will use reasonable best efforts to cooperate with Purchasers in the preparation of any filings and in appearances made before the PUCT, as appropriate, in support of Purchasers’ proposal to acquire Oncor and Oncor Holdings, and Purchasers, Oncor and Oncor Holdings agree to use reasonable best efforts to make a single filing by the parties seeking prior approval by the PUCT of the Purchase Transaction;

WHEREAS, Oncor Holdings and Oncor have agreed to operate in the ordinary course of business and materially consistent with the 2017-2018 Plan upon signing of this Letter Agreement, 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:

Any costs of goodwill of Parent or its affiliates (including the pre-existing goodwill recognized by Oncor) will not be included in rate base, cost of capital, or operating expenses in future Oncor ratemaking proceedings. Write-downs or write-offs of goodwill will not be included in the calculation of net income for dividend payment purposes.

42. Tangible and Quantifiable Benefits. At a minimum, Oncor will provide the following tangible and quantifiable benefits associated with the merger. Oncor will provide monthly bill credits to electric delivery rates for ultimate credits to customers in an amount equal to 90% of any interest rate savings achieved until: final rates are set in the next Oncor base rate case after the Oncor base rate case currently filed. Savings will not be included in credits if already realized in rates. Interest Rate Savings refers to the improvement in Oncor’s borrowing costs post-close relative to those costs as of June 30, 2017 due to improvement in credit ratings and/or improvement in market spreads. Until final rates are set in the next Oncor base rate case after the Oncor base rate case that is currently filed, Oncor will file a report with the Commission every six months detailing any interest rate savings determined by the amount of debt issued by Oncor by at least 0.15% (amounts above 0.15% being based on actual interest rate savings by Oncor) and demonstrating a calculation of the credit. Parent and Oncor agree to work in good faith with interested parties, including TXU Energy Retail Company LLC, Texas Energy Association for Marketers, Alliance for Retail Markets, and NRG Companies, to determine an acceptable method for implementation of any bill credit to effectuate this commitment, as approved by the Commission. At a minimum, Oncor shall provide retail electric providers 45-day notice of the amount of any customer credits (e.g., for each customer class, the amount per kwh or per-customer credit that would apply) prior to the effective date of the credits and shall implement updated bill credits simultaneously with other changes in Oncor’s rates. In addition, one year after closing, Oncor will present a merger synergy savings analysis to the Commission and provide monthly bill credits to electric rates for inclusion in customer bills in an

amount equal to 90% of any synergy savings until final rates are set in the next Oncor base rate proceeding, in which any total synergy savings shall be reflected in Oncor’s rates.

43. LLC Agreements. The Oncor Holdings and Oncor LLC Agreements shall be amended to the extent necessary to effect all of the commitments herein.

44. Competitive Shopping Platforms. Parent agrees that neither Oncor nor Oncor's subsidiaries will host or allow the Oncor name, trademark, brand, logo, or other identifying brand features to be used to promote a competitive retail electric shopping website.

Distributions may be made, at such times and in such amounts as determined by the Board of Directors of New HoldCo (the “Board”), on a pro rata basis with respect to the Class A Units, Class B Units and the Class C Units then outstanding. Such determination shall be made by the majority vote of the Board. Notwithstanding the foregoing, to the extent of available cash and to the extent not prohibited by New HoldCo’s or its subsidiaries’ financing agreements with lenders that are not Unitholders, New HoldCo shall make pro rata quarterly distributions to its Unitholders with respect to the taxable income generated by New HoldCo and its subsidiaries allocable to the Unitholders in a manner to be set forth in the LLC Agreement, assuming the highest applicable tax rates.

Call Option:	From and after the Closing Date, Parent shall have the right to purchase any or all of the number of Class A Units issued on the Closing Date (but not Class B Units) at fair market value (calculated by an expert appraisal firm based on the fair market value of the Class A Units at the time of the exercise of the call option) in exchange for cash or shares of common stock of Parent or a combination thereof, at the election of Parent.
Capital Calls and Preemptive Rights:	The Unitholders will be entitled to customary preemptive rights in respect of issuances by Parent BidCco or any of its controlled subsidiaries. If the Board determines to pay down existing debt of New HoldCo or any of its controlled Subsidiaries, or if New HoldCo is unable to service its existing debt, New HoldCo shall initiate a capital call to the Unitholders on a pro rata basis with proportional adjustments to each Unitholder’s membership interest at fair market value. To the extent that any Unitholder elects not to participate pro rata in the capital calls to pay down the applicable debt, the Unitholders participating in the capital call will retain the right to contribute the shortfall amount of equity capital and the non- contributing Unitholders will be diluted.
Information Rights:	New HoldCo shall grant customary information rights to Unitholders.

Voting Rights:

Each Class A Unit and Class B Unit confers the holder one vote per unit, subject to the restrictions on the Class C Units. Each Class C Unit confers upon the holder one vote per Class C Unit unless: the number of Class C Units outstanding, as a percentage of the total number of Units outstanding exceeds 50.0%, then the voting rights of each Class C Unit shall decrease proportionately such that the total voting power of all Class C Units as a class does not exceed 50.0% of the aggregate voting power of New HoldCo; provided, that this restriction on the voting of the Class C Units shall cease once Parent owns more than 80% of the total outstanding Units.

Conversion:

Each Class A Unit and Class B Unit is convertible into a Class C Unit upon the transfer thereof to Parent.

Board Representation:

The Board shall initially consist of eight directors, four of which shall be selected by Parent (the “Class C Directors”) and four of which shall be selected by the Rollover Trust and the Non-Rollover Trust proportionally based on the number of total Units held by the Trusts (the “Class A Directors” or the “Class B Directors”, as applicable), and shall serve until successors are duly appointed. Once Parent owns more than 80% of the total outstanding Units, the directors of New HoldCo shall be selected by Parent, the Rollover Trust and the Non-Rollover Trust proportionally based on the number of total Units held by such members. The LLC Agreement shall contain a customary waiver of fiduciary duties in respect of the members of the Board. The Board shall act by action of the majority of the whole Board.

Oncor will provide monthly bill credits to electric delivery rates for ultimate credits to customers in an amount equal to 90% of any interest rate savings achieved until: final rates are set in the next Oncor base rate case after the Oncor base rate case currently filed. Savings will not be included in credits if already realized in rates. Interest Rate Savings refers to the improvement in Oncor’s borrowing costs post-close relative to those costs as of June 30, 2017 due to improvement in credit ratings and/or improvement in market spreads. Until final rates are set in the next Oncor base rate case after the Oncor base rate case that is currently filed, Oncor will file a report with the Commission every six months detailing any interest rate savings determined by the amount of debt issued by Oncor by at least 0.15% (amounts above 0.15% being based on actual interest rate savings by Oncor) and demonstrating a calculation of the credit. Parent

and Oncor agree to work in good faith with interested parties, including TXU Energy Retail Company LLC, Texas Energy Association for Marketers, Alliance for Retail Markets, and NRG Companies, to determine an acceptable method for implementation of any bill credit to effectuate this commitment, as approved by the Commission. At a minimum, Oncor shall provide retail electric providers 45-day notice of the amount of any customer credits (e.g., for each customer class, the amount per kwh or per-customer credit that would apply) prior to the effective date of the credits and shall implement updated bill credits simultaneously with other changes in Oncor’s rates. In addition, one year after closing, Oncor will present a merger synergy savings analysis to the Commission and provide monthly bill credits to electric rates for inclusion in customer bills in an amount equal to 90% of any synergy savings until final rates are set in the next Oncor base rate proceeding, in which any total synergy savings shall be reflected in Oncor’s rates.
