of any bond and without proof of actual damages), including an order of the Bankruptcy Court or other court of competent jurisdiction requiring any Party to comply promptly with any of its obligations hereunder, in addition to any other remedy at
law or equity; provided, however, that no Party shall be liable for special, indirect, consequential, or punitive damages arising out of, in connection with, or relating to this Agreement or any agreement or instrument contemplated
hereby. 
 10.14. Several, Not Joint, Claims. The agreements, representations, warranties, and obligations of the Parties under this
Agreement are, in all respects, several and not joint. 
 10.15. Severability. If any term or other provision of this Agreement shall
be held by a court of competent jurisdiction to be invalid, illegal or unenforceable, 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 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 unenforceable, the Parties shall negotiate in good faith to modify this Agreement so as to
effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the essential terms and conditions of this Agreement are fulfilled to the extent possible. 

10.16. Remedies Cumulative. All rights, powers, and remedies provided under this Agreement or otherwise available in respect hereof at
law or in equity shall be cumulative and not alternative, and the exercise of any right, power, or remedy thereof by any Party shall not preclude the simultaneous or later exercise of any other such right, power, or remedy by such Party.

its Subsidiaries are able to obtain and have in full force and effect as of the Closing insurance that covers the foregoing matters on terms and conditions that are satisfactory to Parent in its sole discretion (the “Asbestos Insurance
Policy”), then the Asbestos Escrow Agreement shall not be funded (and, for the avoidance of doubt, subject to Section 1.7(a)(vii), such amount shall be included in the Accessible Account Deposit). If, during the 18-month period

binding on the parties hereto for all purposes of this Agreement and the Plan of Reorganization. As used herein, “Audit Procedures” means those procedures for the audit of the Cash and Cash Equivalents of the Company, as of the
Closing Date, to be conducted by the Auditor, such procedures to be developed in writing by the Auditor prior to the Closing consistent with this Agreement and reasonably acceptable to the Company and Parent. “Adjusted Company Cash
Amount” means the amount of Cash and Cash Equivalents of the Company at Closing as determined in accordance with this Section 1.11 and, for the avoidance of doubt, excluding any Emergence Fees or Emergence Payments. If the
Adjusted Company Cash Amount is greater than the Estimated Company Cash Amount, Parent shall deliver by wire transfer of immediately available funds to the EFH Plan Administrator Board an amount equal to the difference in such amounts, to be
distributed in accordance with the Plan of Reorganization. If the Adjusted Company Cash Amount is less than the Estimated Company Cash Amount, Parent shall receive, by wire transfer of immediately available funds from the EFH Plan Administrator
Board, an amount equal to the difference in such amounts, in accordance with the Plan of Reorganization. 
 Section 1.12 Adjustments
to Allocations. For the avoidance of doubt, the provisions in Sections 1.7 through 1.11 are intended to ensure the satisfaction of the continuity of interest requirement under Sections 355 and 368 of the Code, and reasonable
adjustments shall be made, including by issuing additional shares of Parent Common Stock (with a corresponding decrease in the Merger Sub Cash Amount), to the extent Parent reasonably concludes such adjustments are necessary to ensure such
satisfaction, and further reasonable adjustments shall be made to the allocation of Parent Common Stock and the Merger Sub Cash Amount to account for the payment of Cash to the Holders of Allowed EFH Non-Qualified Benefit Claims (as defined in the
Plan of Reorganization) in accordance with the Plan of Reorganization.

 Effect of
the Merger on Capital Stock; 
 Exchange of Certificates 

Section 4.1 Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the
Company, reorganized EFIH, Parent, Merger Sub, the holder of the Reorganized EFH Class A Common Stock, the holder of the Reorganized EFH Class B Common Stock, or the sole member of Merger Sub: 

(a) Stock Consideration. On the terms set forth in this Agreement, at the Closing, (i) the share of Reorganized EFH Class A
Common Stock issued and outstanding immediately prior to the Effective Time (the “Class A Share”) shall be converted into the right to receive the Class A Stock Consideration (such consideration, the “Class A Merger
Consideration”) and (ii) the share of Reorganized EFH Class B Common Stock issued and outstanding immediately prior to the Effective Time (the “Class B Share” and, together with the Class A Share, the
“Shares”) shall be converted into the right to receive the Class B Stock Consideration (such consideration, the “Class B Merger Consideration” and, together with the Class A Merger Consideration, the
“Merger Consideration”). For the avoidance of doubt, the EFH Stakeholders and EFIH Stakeholders shall, notwithstanding the foregoing, continue to have the right to receive such cash consideration (if any) to be paid out in
accordance with the Plan of Reorganization. All of the Shares, when so converted (including if a Share is converted into the right to receive Merger Consideration having no value), shall no longer be outstanding and shall automatically be cancelled
and shall cease to exist, and each holder of a certificate that immediately prior to the Effective Time represented a Share (each a “Certificate”) and each holder of a Share held in uncertificated book-entry form (the
“Book-Entry Shares”) shall cease to have any rights with respect thereto, except the right to receive the Class A Stock Consideration or Class B Stock Consideration (including any cash in lieu of fractional shares of Parent
Common Stock to be issued or paid in consideration therefor in accordance with Section 4.2(g)), as applicable, upon delivery of a fully completed and validly executed letter of transmittal and, in the case of certificated Shares, upon
the surrender of such Certificate(s) and at the times provided in this Agreement or the Plan of Reorganization. 

  
 20 

 (b) Merger Sub. Each membership interest in Merger Sub issued and outstanding immediately
prior to the Effective Time shall be converted into and become one (1) membership interest unit in the Surviving Company, which shall be held by Parent, and shall constitute the only issued and outstanding limited liability company membership
interests of the Surviving Company. 
 Section 4.2 Exchange of Certificates. 

(a) Exchange Agent. Prior to the Closing, the Company shall enter into an exchange agent agreement with an exchange
agent selected by Parent with the Company’s prior approval (such approval not to be unreasonably withheld, conditioned or delayed) (the “Exchange Agent”). The Exchange Agent shall act as exchange agent, registrar and transfer
agent for the purpose of exchanging Certificates or Book-Entry Shares, for the Merger Consideration applicable thereto. At or prior to the Effective Time, Parent shall deposit with the Exchange Agent, for the benefit of the holders of Shares
immediately prior to the Effective Time, for exchange in accordance with this Article IV, a sufficient number of shares of Parent Common Stock to issue the aggregate Stock Consideration. All such Parent Common Stock deposited with the
Exchange Agent is hereinafter referred to as the “Exchange Fund”. 
 (b) Exchange Procedures. As soon
as reasonably practicable after entry of the EFH Confirmation Order (as defined below) and in any event not later than the third (3rd) Business Day following the Effective Time, Parent shall cause the Exchange Agent to mail to each holder of
record of a Certificate or Book-Entry Share that immediately prior to the Effective Time represented outstanding Shares, (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to such
Certificates and Book-Entry Shares shall pass, only upon delivery of such Certificates or Book-Entry Shares, as applicable, to the Exchange Agent and shall be in such form and have such other provisions as Parent and the Company may reasonably
specify) and (ii) instructions for use in surrendering such Certificates or Book-Entry Shares in exchange for whole shares of Parent Common Stock and cash in lieu of fractional shares pursuant to Section 4.2(g). Upon surrender of a
Certificate or Book-Entry Share for cancellation to the Exchange Agent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may reasonably be required
by the Exchange Agent, the holder of such Certificate or Book-Entry Share shall be entitled to receive in exchange therefor (as promptly as possible but in any event within three (3) Business Days following such surrender) that number of whole
shares of Parent Common Stock (which shall be in uncertificated book-entry form through a direct registration system unless a physical certificate is requested), that such holder has the right to receive pursuant to the provisions of this Article
IV and cash in lieu of any fractional share of Parent Common Stock in accordance with Section 4.2(g), and each Certificate or Book Entry Share so surrendered shall forthwith be cancelled. In the event of a transfer of ownership of
Shares that is not registered in the transfer records of the Company, the proper number of shares of Parent Common Stock may be issued to 

  
 21 

 
a Person other than the Person in whose name the Certificate or Book-Entry Share so surrendered is registered if such Certificate or Book-Entry Share shall be properly endorsed or otherwise be in
proper form for transfer and the Person requesting such issuance shall pay any transfer or other taxes required by reason of the issuance of shares of Parent Common Stock to a Person other than the registered holder of such Certificate or Book-Entry
Share or establish to the reasonable satisfaction of Parent that such tax has been paid or is not applicable. Until surrendered as contemplated by this Section 4.2(b), each Certificate and Book-Entry Share shall be deemed at any time
after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration applicable thereto, which the holder thereof has the right to receive in respect of such Certificate or Book-Entry Share pursuant to the
provisions of this Agreement, including, for the avoidance of doubt, cash in lieu of any fractional share of Parent Common Stock payable as part of the Merger Consideration applicable thereto, in accordance with Section 4.2(g), together
with any unpaid dividends or distributions thereon with a record date on or after the Effective Time payable at such time in accordance with Section 4.2(k). No interest shall be paid or will accrue on the Merger Consideration or any cash
payable to holders of Certificates or Book-Entry Shares pursuant to the provisions of this Article IV. The portion of the Merger Consideration receivable by any holder of a Certificate or Book-Entry Shares shall be aggregated with respect to
all Shares held by such holder immediately prior to the Effective Time, and following such aggregation, the Exchange Agent shall determine the number of whole and fractional shares of Parent Common Stock to which such holder is entitled for purposes
of this Article IV. 
 (c) Transfers. From and after the Effective Time, there shall be no transfers on the
stock transfer books of the Surviving Company of the Shares that were outstanding immediately prior to the Effective Time. If, after the Effective Time, any Certificate or Book-Entry Share is presented to the Surviving Company, Parent or the
Exchange Agent for transfer, it shall be cancelled and exchanged for the Merger Consideration applicable thereto to which the holder thereof is entitled pursuant to and in accordance with this Article IV, together with any unpaid dividends or
distributions thereon with a record date on or after the Effective Time payable at such time in accordance with Section 4.2(k). 

(d) Lost, Stolen or Destroyed Certificates. In the event any Certificate shall have been lost, stolen or destroyed, upon
the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such Person of a bond in customary amount and upon such terms as may be required by Parent as
indemnity against any claim that may be made against it or the Surviving Company with respect to such Certificate, the Exchange Agent will treat such Person as having delivered his, her or its Certificate for purposes of Section 4.2(b).

 (e) Withholding Rights. Each of Parent and the Surviving Company shall be entitled to deduct and withhold from any
consideration otherwise payable pursuant to this Agreement such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any other applicable state, local or foreign Tax (as defined below) Law.
To the extent that amounts are so withheld by the Surviving Company or Parent, as the case may be, such withheld amounts (i) shall be remitted by Parent or the Surviving Company, as applicable, to the applicable Governmental Entity, and
(ii) shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made by the Surviving Company or Parent, as the case may be. 

  
 22 

 (f) No Further Ownership Rights in the Shares. After the Merger, no
dividends or other distributions with respect to capital stock of the Surviving Company with a record date on or after the Effective Time shall be paid to the holder of any un-surrendered Certificate or Book-Entry Shares. The shares of Parent Common
Stock issued, and cash paid (if any), in accordance with the terms of this Article IV upon the surrender of Certificates or Book-Entry Shares, as applicable, and delivery of a duly completed and validly executed letter of transmittal,
including any cash paid pursuant to Section 4.2(g), shall be deemed to have been issued and paid in full satisfaction of all rights pertaining to such Certificates or Book-Entry Shares. 

(g) Fractional Shares. 

(i) No fractional shares of Parent Common Stock shall be issued upon the surrender for exchange of Certificates or Book-Entry
Shares, no dividend or distribution by Parent shall relate to such fractional share of Parent Common Stock and such fractional share of Parent Common Stock shall not entitle the owner thereof to vote or to any rights of a shareholder of Parent but,
in lieu thereof, each holder of such Certificate or Book-Entry Shares shall be entitled to a cash payment in accordance with the provisions of this Section 4.2(g). 

(ii) As promptly as practicable following the Effective Time, the Exchange Agent shall determine the excess of (A) the
number of whole shares of Parent Common Stock delivered to the Exchange Agent by Parent pursuant to Section 4.2(a) representing the EFH Stock Consideration over (B) the aggregate number of whole shares of Parent Common
Stock to be distributed to former holders of Shares pursuant to Section 4.2(b) (such excess being herein called the “Excess Shares”). Following the Effective Time, the Exchange Agent shall, on behalf of former
shareholders of the Company, sell the Excess Shares at then-prevailing prices on the NYSE all in the manner provided in Section 4.2(g)(iii). The parties hereto acknowledge that payment of the cash consideration in lieu of issuing
fractional shares of Parent Common Stock was not separately bargained for consideration but merely represents a mechanical rounding off for purposes of avoiding the expense and inconvenience to Parent that would otherwise be caused by the issuance
of fractional shares of Parent Common Stock. 
 (iii) The sale of the Excess Shares by the Exchange Agent shall be executed
on the NYSE through one or more member firms of the NYSE and shall be executed in round lots to the extent practicable. The Exchange Agent shall use reasonable efforts to complete the sale of the Excess Shares as promptly as practicable following
the Effective Time, in the Exchange Agent’s sole judgment, consistent with obtaining the best execution of such sales in light of prevailing market conditions. Until the net proceeds of such sale or sales have been distributed to the holders of
Certificates formerly representing Shares or Book-

  
 23 

 
Entry Shares, the Exchange Agent shall hold such proceeds in trust for such holders (the “Common Shares Trust”). The Surviving Company shall pay all commissions, transfer taxes
and other out-of-pocket transaction costs, including the expenses and compensation of the Exchange Agent incurred in connection with such sale of the Excess Shares. The Exchange Agent shall determine the portion of the Common Shares Trust to which
each former holder of Shares is entitled, if any, by multiplying the amount of the aggregate net proceeds composing the Common Shares Trust by a fraction, the numerator of which is the fractional share of Parent Common Stock to which such former
holder of Shares would otherwise be entitled pursuant to Section 4.1(a) and the denominator of which is the aggregate amount of fractional shares of Parent Common Stock to which all former holders of Shares would otherwise be entitled
pursuant to Section 4.1(a). 
 (iv) As soon as practicable after the determination of the amount of cash, if any,
to be paid to holders of Certificates formerly representing Shares or Book-Entry Shares with respect to any fractional share of Parent Common Stock, the Exchange Agent shall pay such amounts to such holders of Certificates formerly representing
Shares or Book-Entry Shares, without interest, subject to and in accordance with the terms of Section 4.2(b). 

(h) Termination of Exchange Fund. Any portion of the Exchange Fund or Common Shares Trust that remains undistributed for
one hundred eighty (180) days after the Effective Time shall be delivered to Parent, upon demand, and any holders of the Certificates or Book-Entry Shares who have not theretofore complied with this Article IV shall thereafter look only
to Parent for payment of their portion of the Merger Consideration (including any cash in lieu of fractional shares of Parent Common Stock) and any dividends or distributions with respect to Parent Common Stock with a record date on or after the
Effective Time. 
 (i) No Liability. None of Parent, the Company, EFIH, Merger Sub, the Surviving Company or the
Exchange Agent or any of their respective directors, officers, employees, representatives and agents shall be liable to any Person in respect of any shares of Parent Common Stock, any unpaid dividends or distributions with respect thereto with a
record date after the Effective Time or any cash in lieu of fractional shares of Parent Common Stock, in each case delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If any Certificate or Book-Entry
Shares shall not have been surrendered prior to the earlier of (i) any time set forth in the terms of the Plan of Reorganization and (ii) five (5) years after the Effective Time (or immediately prior to such earlier date on which any
portion of the Stock Consideration (including any cash in lieu of fractional shares payable to a holder of such Certificate formerly representing Shares or Book-Entry Shares pursuant to this Article IV) or any dividends or distributions
payable with a record date on or after the Effective Time with respect to any shares of Parent Common Stock comprising the Stock Consideration, would escheat to or become the property of any Governmental Entity), any such Stock Consideration,
dividends, and cash shall, to the extent permitted by applicable Law, become the property of the Surviving Company, free and clear of all claims or interest of any Person previously entitled thereto. 

  
 24 

 (j) Investment of Exchange Fund. The Exchange Agent shall invest any cash
in the Exchange Fund or Common Shares Trust as directed by Parent in (i) short-term obligations of the United States of America (the “U.S.”), (ii) short-term obligations for which the full faith and credit of the U.S. is
pledged to provide for the payment of principal and interest and/or (iii) short-term commercial paper rated the highest quality by each of Moody’s Investors Service Inc. and Standard and Poor’s Ratings Service. Any interest and other
income resulting from such investments shall be paid to Parent, which shall also be responsible for any tax on such income. Parent shall promptly replace any cash held in the Exchange Fund or Common Shares Trust with the Exchange Agent lost through
any investment made pursuant to this Section 4.2(j). 
 (k) Distributions with Respect to Unexchanged
Shares. After the Merger, no dividends or other distributions with respect to shares of Parent Common Stock with a record date on or after the Effective Time shall be paid to the holder of any un-surrendered Certificate or Book-Entry Shares
until such Certificate or Book-Entry Shares is surrendered for exchange in accordance with this Article IV. Subject to the effect of applicable Law, following surrender of any such Certificate or Book Entry Shares, there shall be issued
and/or paid to the holder of the shares of Parent Common Stock issued in exchange therefor, without interest, at the time of such surrender, any unpaid dividends or other distributions with a record date on or after the Effective Time
theretofore payable with respect to such shares of Parent Common Stock. 
 Section 4.3 Adjustments to Prevent Dilution.
Notwithstanding the foregoing, if from the date of this Agreement until the earlier of (i) the Effective Time and (ii) the termination of this Agreement in accordance with Article VIII, the outstanding shares of Reorganized EFH
Common Stock are changed into a different number of shares or a different class, by reason of any stock dividend, subdivision, reclassification, recapitalization, split, combination, consolidation or exchange of shares, or any similar event occurs,
then any number or amount contained herein which is based upon the number of shares of Reorganized EFH Common Stock will be appropriately adjusted.

pending or, to the Knowledge of the Company, threatened audits or investigations by any Governmental Entity involving any Assumed Plan that would reasonably be expected to result in material liability to the Company or any of its Subsidiaries or to
Parent. 

  
 38 

 (vi) Except for any payments made at or prior to the Effective Time, none of the
execution of this Agreement, the consummation of the transactions contemplated by this Agreement, nor a termination or resignation of employment following the Effective Time will result in an obligation of Parent or the Surviving Company after the
Effective Time with respect to any Non-Oncor Employee to severance pay or any material increase in severance pay. Except as set forth in Section 5.1(h)(vi) of the Company Disclosure Letter, neither the execution of this Agreement nor the

by-laws, limited liability company operating agreements, and any other organizational document of Parent, the Company or any of the Company’s Subsidiaries and insurance policies maintained by Parent, the Company or any of the Company’s
Subsidiaries for indemnification or advancement of expenses, neither Parent nor the Company or any of its Subsidiaries will have any obligations or liabilities with respect to any employees of Reorganized TCEH or its Subsidiaries or the Contributed
Plans following the Closing Date. 
 The term “Designated Officer” when used in this Agreement shall mean

 51 

 
being agreed that disclosure of any item in any section or subsection of the Parent Disclosure Letter shall be deemed disclosure with respect to any other section or subsection of the Parent
Disclosure Letter to which the relevance of such item is reasonably apparent from the information disclosed, provided that no such disclosure shall be deemed to qualify Section 5.2(f), unless expressly set forth in
Section 5.2(f), of the Parent Disclosure Letter)), Parent and Merger Sub each hereby represent and warrant to the Company and EFIH, as of the date hereof and as of the Closing Date, that: 

(a) Organization, Good Standing and Qualification. Each of Parent and Merger Sub is a legal entity duly organized,
validly existing and in good standing under the Laws of its respective jurisdiction of organization and has all requisite corporate or similar power and authority to own, lease and operate its properties and assets and to carry on its business as
presently conducted and is qualified to do business and is in good standing as a foreign corporation in each jurisdiction where the ownership, leasing or operation of its assets or properties or conduct of its business requires such qualification,
except where the failure to be so organized, qualified or in such good standing, or to have such power or authority, has not had and would not have, individually or in the aggregate, a Parent Material Adverse Effect (as defined below). Parent has
made available to the Company a complete and correct copy of the certificate of formation and operating agreement or comparable governing documents of each of Parent and Merger Sub, each as amended through the date hereof. 

(b) Capital Structure. 

(i) The authorized capital stock of Parent consists of 800,000,000 shares of Parent Common Stock, of which 461,995,594 shares
of Parent Common Stock were issued and outstanding as of the date hereof and 100,000,000 shares of Serial Preferred Stock, none of which is issued or outstanding on the date hereof. All of the outstanding shares of Parent Common Stock have been duly
authorized and are validly issued, fully paid and nonassessable. As of the date hereof, other than up to 4,600,000 shares of Parent Common Stock issuable pursuant to the (A) terms of outstanding awards under employee incentive awards for
employees of Parent, or (B) pursuant to this Agreement, there were no options to purchase shares of Parent Common Stock issued and outstanding. Except as set forth in this Section 5.2(b) there are no preemptive or other outstanding
rights, options, warrants, conversion rights, stock appreciation rights, performance units, redemption rights, repurchase rights, agreements, arrangements, calls, commitments or rights of any kind that obligate Parent or any of its Subsidiaries to
issue or sell any shares of capital stock or other equity securities of Parent or any of its Subsidiaries or any securities or obligations convertible or exchangeable into or exercisable for, or giving any Person a right to subscribe for or acquire,
any equity securities of Parent or any of its Subsidiaries, and no securities or obligations evidencing such rights are authorized, issued or outstanding except in connection with the Merger. 

  
 52 

 (ii) Upon any issuance of shares of Parent Common Stock pursuant to this
Agreement, such shares of Parent Common Stock will be duly authorized, validly issued, fully paid and non-assessable, approved for listing on the NYSE, subject only to official notice of issuance, and freely saleable and not subject to any resale
restrictions except to the extent such restrictions are due to the status of the holder thereof. 
 (c) Corporate
Authority. No vote of holders of capital stock of Parent is necessary to approve this Agreement, the Oncor Letter Agreement, the Closing Date Transactions, or the other transactions contemplated by this Agreement. Each of Parent and Merger Sub
has all requisite corporate or limited liability company, as applicable, power and authority and has taken all corporate or limited liability company, as applicable, action necessary in order to execute, deliver and perform its obligations under
this Agreement, the Oncor Letter Agreement and any other agreement contemplated herein to be entered into by Parent or Merger Sub. This Agreement, the Plan Support Agreement and the Oncor Letter Agreement have been duly executed and delivered by
each of Parent and Merger Sub and each constitutes a valid and binding obligation of Parent and Merger Sub. This Agreement and the Oncor Letter Agreement are enforceable against each of Parent and Merger Sub in accordance with its terms, subject to
the Bankruptcy and Equity Exception. 
 (d) Governmental Filings; No Violations; Etc. 

(i) Other than the Vermont Insurance Approval, FERC Approval, the PUCT Approval, the FCC Approval, and filings in respect
thereof and the filings and/or notices (A) pursuant to Section 1.5, (B) required as a result of facts or circumstances solely attributable to the Company or its Subsidiaries, a direct or indirect change of control thereof, or
the operation of their businesses, (C) under the HSR Act and (D) under the Securities Act with respect to any registration statement to be filed with the SEC on Form S-4 (the “Form S-4”) or other applicable registration
statement in connection with the issuance by Parent of Parent Common Stock issuable pursuant to this Agreement, (E) under the Exchange Act, (F) under any securities or “blue sky” laws of any jurisdiction in connection with the
issuance by Parent of Parent Common Stock issuable pursuant to this Agreement, and (G) with the NYSE in connection with the listing by Parent on the NYSE of the shares of Parent Common Stock issuable pursuant to this Agreement (other than those
items set forth in clauses (A) and (B), all such approvals being collectively the “Parent Approvals”), no notices, reports or other filings are 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 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. 

  
 53 

 (ii) The execution, delivery and performance of this Agreement by Parent and
Merger Sub do 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 or the comparable governing instruments of any of Parent’s Subsidiaries; (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 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. 

  
 54 

 (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 and (2) any fraud, known to Parent, whether or not material, that involves 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 

  
 55 

 
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, 2015, 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, 2015, including the notes thereto, included in the Company Reports, (B) incurred in the ordinary course of business consistent with past practice since December 31, 2015, (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 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); 

  
 56 

 (ii) any adoption, implementation, promulgation, repeal, modification,
reinterpretation or proposal of any rule, regulation, ordinance, order, protocol or any other Law of or by any national, regional, state or local regulatory Governmental Entity (including, for the avoidance of doubt, the RTOs); 

(iii) changes or developments generally affecting electric transmission or distribution systems (other than changes or
developments that render operationally unusable any facility or property of Parent or 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 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 (solely as the Plan of
Reorganization relates to the E-Side Debtors) shall not constitute, or be deemed to contribute, to a Parent Material Adverse Effect. 

  
 57 

 (g) Litigation. 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. 
 (h) Available Funds. Parent and Merger Sub
currently have available to them, and on or before the Effective Time, will have available to them, (i) all funds necessary to satisfy Parent’s and Merger Sub’s obligations to consummate the Merger and the other transactions required
of it by this Agreement, including funding the Merger Sub Cash Amount, the DIP Repayment and the payment of all of Parent’s and Merger Sub’s fees and expenses related to the foregoing and to satisfy all other payment obligations required
to be paid or satisfied by Parent or Merger Sub in connection therewith, and (ii) the authority to issue shares of Parent Common Stock necessary to effect the Merger described in Section 1.4. Parent and Merger Sub acknowledge and
agree that the consummation of the DIP and Second Lien Note Repayments, the Merger, and the other transactions contemplated by this Agreement, is not conditional upon the receipt by Parent or Merger Sub or availability of the proceeds of any
financing and that any failure by Parent or Merger Sub to consummate the Merger on the Closing Date (provided that at such time the conditions to the Closing set forth in Section 7.1 and 7.2 are otherwise satisfied or are
to be satisfied at the Closing), by reason of absence of financing, shall constitute a breach by Parent and/or Merger Sub of this Agreement. 

(i) Merger Sub. All of the issued and outstanding membership interests of Merger Sub are validly issued and outstanding
and are, and at the Effective Time will be, owned by Parent. Merger Sub has not conducted any business prior to the date hereof and has no, and prior to the Effective Time will have no, assets, liabilities or obligations of any nature other than
those incident to its formation and pursuant to this Agreement. 
 (j) Brokers. No agent, broker, finder or investment
banker is entitled to any brokerage, finder’s or other fee or commission in connection with the transactions contemplated by this Agreement based upon arrangements made by or on behalf of Parent or Merger Sub for which the Company could have
any liability prior to the Effective Time. 
 (k) Taxes. Merger Sub is classified as a disregarded entity and as a
division of Parent for federal income tax purposes. Parent is classified as a corporation for federal income tax purposes. Parent and Merger Sub have not taken or agreed to take any action, and are not aware of any facts or circumstances, in each
case, that would prevent or impede, or would reasonably be expected to prevent or impede, the Merger from qualifying as a reorganization within the meaning of Section 368(a) of the Code. 

  
 58 

 (l) Regulatory Status. Parent is a public utility holding company under
the Public Utility Holding Company Act of 2005 (“PUHCA”). Merger Sub is not a public utility holding company under PUHCA. Neither Parent nor Merger Sub is a public utility under the Federal Power Act. 

(m) Oncor Entities. Parent and Merger Sub acknowledge that the ability of the Company and EFIH to exercise control over
the Oncor Entities, or cause the Oncor Entities to take any action, is limited due to applicable Law and the provisions set forth in the Oncor Agreements. 

(n) Certain Subsidiaries. Parent and Merger Sub acknowledge and agree that, for purposes of determining the satisfaction
of the condition set forth in Section 7.2(a), none of the representations and warranties of the Company and EFIH in this Agreement shall be deemed to be untrue, or fail to be true, due to the existence of any liability of a Spin-Off
Entity or any other Subsidiary of the Company that will dissolve, liquidate, merge out of existence or be abandoned in accordance with the Plan of Reorganization and applicable Law, in each case which will be fully and unconditionally discharged at
or prior to the Effective Time pursuant to the Plan of Reorganization or otherwise. 
 (o) Disclaimer of Other
Representations and Warranties. EACH OF PARENT AND MERGER SUB (INDIVIDUALLY AND ON BEHALF OF THEIR RESPECTIVE SUBSIDIARIES) ACKNOWLEDGES AND AGREES THAT NEITHER THE COMPANY NOR ANY OF ITS SUBSIDIARIES MAKES ANY REPRESENTATION OR WARRANTY,
WHETHER EXPRESS OR IMPLIED, AS TO ANY MATTER WHATSOEVER EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT OR THE ONCOR LETTER AGREEMENT, AS APPLICABLE, OR IN ANY CERTIFICATE DELIVERED BY THE COMPANY OR ITS SUBSIDIARIES TO PARENT IN ACCORDANCE WITH THE
TERMS HEREOF OR THE ONCOR LETTER AGREEMENT, AND SPECIFICALLY (BUT WITHOUT LIMITING THE GENERALITY OF THE FOREGOING) THAT NEITHER THE COMPANY NOR ANY OF ITS SUBSIDIARIES MAKES ANY REPRESENTATION OR WARRANTY WITH RESPECT TO (X) ANY PROJECTIONS,
ESTIMATES OR BUDGETS OF THE COMPANY AND ITS SUBSIDIARIES DELIVERED OR MADE AVAILABLE TO PARENT (OR ANY OF ITS AFFILIATES, OFFICERS, DIRECTORS, MANAGERS, EMPLOYEES OR REPRESENTATIVES) OF FUTURE REVENUES, RESULTS OF OPERATIONS (OR ANY COMPONENT
THEREOF), CASH FLOWS OR FINANCIAL CONDITION (OR ANY COMPONENT THEREOF) OF THE COMPANY AND/OR ANY OF ITS SUBSIDIARIES OR (Y) THE FUTURE BUSINESS AND OPERATIONS OF THE COMPANY AND/OR ANY OF ITS SUBSIDIARIES.

Parent, the Company, its Subsidiaries and their respective Representatives. 
 (d) Except as set forth in
Section 6.2(e), neither the Company Board nor the EFIH board of managers, nor any committee thereof shall allow the Company or EFIH, as the case may be, or any of their respective Subsidiaries (other than the Oncor Entities, subject to
Section 6.21) to execute or enter into, any binding letter of intent, memorandum of understanding, term sheet, agreement or commitment (other than an Acceptable Confidentiality Agreement), that constitutes an Acquisition Proposal, or
requires, or would reasonably be expected to cause, the Company or EFIH to terminate this Agreement (a “Company Acquisition Agreement”). 

(e) Prior to the Company or EFIH, as applicable, terminating this Agreement pursuant to Section 8.3(e) or
Section 8.3(f), as the case may be, (A) the Company shall provide prior written notice to Parent of the submission of any Acquisition Proposal for which the Company or EFIH is prepared to terminate this Agreement at least three
(3) Business Days prior to terminating this Agreement, which notice shall specify the material terms and conditions of any such Acquisition Proposal, the identity of the Person making such Acquisition Proposal and a copy of the most current

of an Acquisition Proposal or as a condition to the submission of an Acquisition Proposal, from furnishing the Company Notice), and (B) the Company Board or the board of managers of EFIH, as the case may be, shall have determined in good faith
(in each case, after consultation with its independent financial advisor and outside legal counsel, and based on advice of such counsel) that such Acquisition Proposal is a Superior Proposal, and after such three
(3)

  
 67 

 
Business Days the Company Board or the board of managers of EFIH, as the case may be, may terminate this Agreement pursuant to Section 8.3(e) or Section 8.3(f), as
applicable and enter into a Company Acquisition Agreement, if concurrently with such termination, it determines in its sole discretion after consultation with its independent financial advisor and outside legal counsel, and based on advice of such
counsel, that such Acquisition Proposal is a Superior Proposal and, that as a result, the failure to terminate this Agreement is inconsistent with its fiduciary duties. In determining whether to terminate this Agreement pursuant to
Section 8.3(e) or Section 8.3(f), the relevant board shall take into account all changes to the terms of this Agreement proposed by Parent after the date hereof in response to such a Company Notice, and any other information
deemed relevant or appropriate by such board. The obligations set forth in this Section 6.2(e) are in addition to those set forth in the other provisions of this Section 6.2, including for the avoidance of doubt
Section 6.2(f). 
 (f) Following the entry of the Approval Order, the Company or EFIH shall as promptly as
reasonably practicable (i) and in any event before engaging in, or continuing, any material discussions with any Person (or its Representatives) who submits, or has submitted, an Acquisition Proposal, or providing material information to such
Person (or its Representatives), enter into an Acceptable Confidentiality Agreement with such Person (to the extent an Acceptable Confidentiality Agreement is not already in effect with such Person), and advise Parent in writing of each such
Acquisition Proposal, the material terms and conditions of any such Acquisition Proposal (including any material changes to such material terms and conditions promptly after receipt thereof) and provide to Parent a copy of each Company Acquisition
Agreement relating to such Acquisition Proposal and the identity of such Person and its Representatives; (ii) make available to Parent and Merger Sub any material information that it or its Representatives make available to each such Person
described in preceding clause (i) or its Representatives which was not previously made available to Parent or Merger Sub, concurrently with the making available of such information to such Person or its Representatives; and (iii) inform
Parent and Merger Sub of any material developments with respect to each Acquisition Proposal described in this sentence. The obligations set forth in this Section 6.2(f) shall apply with respect to any Acquisition Proposal submitted
before or after the date hereof, and the Company and EFIH acknowledge and agree that, to the extent an Acquisition Proposal which meets the requirements for discussions or other actions to occur as contemplated by this Section 6.2 is
submitted by or on behalf of a Person with whom the Company or any of its Subsidiaries has previously entered a confidentiality agreement, such obligations set forth in this Section 6.2(f) may require an amendment to such agreement in
order for such Acquisition Proposal to be pursued by the Company or EFIH. To the extent that Parent or any of its Affiliates receive the identity of any other potential acquiror from the Company or EFIH pursuant to this Section 6.2, the
recipient thereof shall maintain the confidentiality of such identity, and shall only share such identity with its legal advisors for purposes of receiving legal advice. 

(g) Notwithstanding anything to the contrary herein, during the period beginning at the date of the entry of the Confirmation
Order and continuing until the earlier of the Termination Date or the Closing Date, the Company and EFIH and their Representatives shall have the right to: (x) solicit, initiate, encourage, induce or facilitate

  
 68 

 
Backup Plan Proposals, including by way of providing access to non-public information concerning the Company or its Subsidiaries to any Person pursuant to an Acceptable Confidentiality Agreement;
(y) enter into, maintain or continue discussions or negotiations with respect to Backup Plan Proposals or otherwise cooperate with or assist or participate in, or facilitate any such inquiries, proposals, discussions or negotiations; and
(z) adopt, approve, recommend, or enter into a definitive agreement with respect to or propose to adopt, approve, recommend, or enter into a definitive agreement with respect to (publicly or otherwise) any such Backup Plan Proposal;
provided, however, that the Company and EFIH shall use commercially reasonable efforts (x) to keep confidential any solicitation, negotiation, facilitation, and documentation by any Debtor of a Backup Plan Proposal and (y) to
enter into confidentiality agreements with any counterparty to any agreement regarding support for and/or financing of a Backup Plan Proposal, which confidentiality agreement provides that the existence and terms of such Backup Plan Proposal shall
be kept confidential and shall not be publicly disclosed, except in each case to the extent required by applicable Law. 

(h) For purposes of this Agreement: 

“Acceptable Confidentiality Agreement” means a confidentiality agreement that contains provisions that are not less favorable
in the aggregate to the Company than those contained in the Confidentiality Agreement and, solely to the extent executed after the date of this Agreement, does not prohibit the Company or any of its Subsidiaries from providing information to Parent
that Parent is expressly entitled to receive from the Company in accordance with this Section 6.2. 
 “Acquisition
Proposal” means any inquiry, proposal or offer from or by a Person (other than Parent or any of its Subsidiaries and their respective agents and Representatives) with respect to (i) a merger, acquisition, consolidation, dissolution,

transaction involving the Company and/or one or more of its Subsidiaries which results in the direct or indirect acquisition of more than 20% of the assets of the Company and its Subsidiaries on a consolidated basis or in the direct or indirect
acquisition of more than 20% of the equity interests or voting power of the Company, EFIH or any of the Oncor Entities provided, however, that a Backup Plan Proposal (as defined below) shall not constitute an Acquisition Proposal. 

“Backup Plan Proposal” means an any inquiry, proposal or offer that (i) would constitute an Acquisition Proposal
(including, for the avoidance of doubt, a standalone plan of reorganization negotiated with existing creditors of the Company or EFIH) but for its express exclusion from the definition of Acquisition Proposal and, (ii) by its terms,
contemplates consummation or closing of such Backup Plan Proposal only after termination of this Agreement other than a termination arising as a result of the adoption, approval, recommendation, or entry into a definitive agreement with respect to
such Backup Plan Proposal. 

  
 69 

 “Superior Proposal” means a bona fide Acquisition Proposal (except that
references to 20% shall be changed to 50%) which the Company Board or the board of managers EFIH, as the case may be, determines in good faith would, if consummated, result in a superior transaction to the Company or EFIH, as applicable, than the
transactions contemplated by this Agreement after consultation with its independent financial advisors and outside legal counsel, and based on advice of such counsel, and, taking into account (x) the likelihood and timing of consummation and
(y) all material legal, financial (including the financing terms of any such proposal), conditionality, regulatory and other aspects of such proposal, in each case as compared to the transactions contemplated by this Agreement.

avoiding the entry or enactment of any permanent, preliminary or temporary injunction or other order, decree, decision, determination, judgment or Law that, individually or in the aggregate, would be reasonably likely to prevent, enjoin or otherwise
prohibit, or materially impair, restrain or restrict, the transactions contemplated by this Agreement or the Plan of Reorganization (solely as the Plan of Reorganization relates to the E-Side Debtors), including Parent and Merger Sub, subject to the
first sentence of the last paragraph of Section 6.3(e), taking all actions required by, and accepting all conditions and/or requirements imposed under the terms of any, consent, registration, order, approval or authorization issued by
any Governmental Entity in connection with the transactions contemplated by this Agreement or the Plan of Reorganization to the extent that any such condition or requirement is a Key Regulatory Term or is not otherwise a Burdensome Condition; and

  
 74 

 (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 (solely as the Plan of Reorganization relates to the E-Side Debtors) 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 (solely as the Plan of Reorganization relates to the E-Side Debtors), 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. 

(e) Acceptable Conditions. Notwithstanding the obligations set forth in this Section 6.3 or elsewhere in
this Agreement, (A) Parent and Merger Sub shall not be required to, and (B) the Company, EFIH and their Subsidiaries (other than the Oncor Entities, subject to Section 6.21) shall not be permitted to, without the prior written
consent of Parent, take any action pursuant to this Section 6.3 or otherwise if the taking of such efforts or action, individually or in the aggregate, would result in a Burdensome Condition. 

“Burdensome Condition” means any term or condition, order, sanction, requirement, law, rule or regulation that, individually
or in the aggregate, would, or would be reasonably expected to have a material and adverse effect on, or change in, the condition (financial or otherwise), business, assets, liabilities or results of operations (i) of Oncor and its
Subsidiaries, taken as a whole, or (ii) of Parent and its Subsidiaries, taken as whole; provided that, for purposes of this clause (ii) Parent and its Subsidiaries, taken as a whole, shall be deemed to be a consolidated group of
entities that is the size and scale of the Oncor Entities; provided, however, that terms or conditions, orders, sanctions, requirements, laws, rules or regulations that result in changes or developments generally affecting electric
transmission or distribution systems in the State of Texas shall not be deemed to be, or contribute to, a Burdensome Condition (except such changes or developments affecting electric transmission or distribution systems in the State of Texas shall
be taken into account in determining whether there has been or is a Burdensome Condition to the extent such changes, or developments have a disproportionate and adverse effect on Oncor and its Subsidiaries, taken as a whole, or Parent and its
Subsidiaries, taken as a whole (where Parent and its Subsidiaries, including the Oncor Entities, are deemed to be a consolidated group of entities that is the size and scale of the Oncor Entities), as compared to other entities engaged in the
relevant business in the State of Texas); provided, further, that, the approval of any of the Key Regulatory Terms, or any comparable condition, requirement or similar item that, in each case, is substantively the same

  
 75 

 
or results in the same effect as any of the Key Regulatory Terms, by the PUCT shall not be deemed to be, or contribute to, a Burdensome Condition, but adverse variations or changes to any of the
Key Regulatory Terms may contribute to, or be, a Burdensome Condition; and provided, further, however, that the PUCT Approval shall be deemed to be a Burdensome Condition (X) if the PUCT Approval does not approve changes of control of
Oncor (a) pursuant to which Parent and its Affiliates will own, directly or indirectly, all of the equity securities of Oncor and (b) pursuant to which Parent and its Affiliates will own, directly or indirectly, all of the equity
securities of Oncor (other than indirect interests in Oncor that are issued to the public, interests issued to directors, officers and employees of the Oncor Entities pursuant to a management equity incentive plan and direct or indirect interests
held by the current members of Oncor and their successors), (Y) if the PUCT Approval imposes (i) any requirement, restriction, limitation or condition on Parent’s ability to, directly or indirectly, appoint, remove and replace from
time to time any individual who serves on the board of directors of Oncor or Oncor Holdings from time to time (and otherwise to fill vacancies on such boards of directors) or the process for the appointment, removal or replacement of such directors
or (ii) imposes any requirement, restriction, limitation or condition on the qualifications for the directors of the Oncor Entities (including the independence thereof) other than requiring that no more than a majority of the directors of Oncor
Holdings and Oncor shall consist of persons who qualify as “independent” in accordance with the rules and regulations of the NYSE, provided that, if any such requirement, restriction, limitation or condition pursuant to this clause
(Y) is only effective during periods in which Parent and its subsidiaries, other than Oncor and Oncor Holdings, have outstanding new debt that is solely or almost entirely dependent on the revenues of Oncor, then such requirement, restriction,
limitation or condition shall not, in and of itself, be deemed to be a Burdensome Condition, or (Z) if the PUCT Approval imposes any requirement, restriction, limitation, condition or obligation that limits or prevents any of the Oncor Entities
from making distributions, dividends or other payments to Parent or its Affiliates, except in the case of this clause (Z), (i) as provided for in the Key Regulatory Terms without modification thereto, or any comparable condition, requirement or
similar item that, in each case, is substantively the same or results in the same effect as any of the Key Regulatory Terms, or (ii) for any condition that would restrict the Oncor Entities from making distributions, dividends or other payments
to Parent or its Affiliates if such distribution, dividend or other payments would cause Oncor’s actual equity ratio to fall below the equity ratio established by the Commission from time to time, as such actual equity ratio appears in
Oncor’s annual Earnings Monitoring Report, and, except in the case of each of clauses (X), (Y) and (Z), as would not cause any nationally recognized rating agency, rating Parent, any of Parent’s Affiliates or any securities issued by
Parent or any of its Affiliates, (1) to assign to Parent, any of its Affiliates (including any Affiliate that is an issuer of indebtedness) or any securities issued by Parent or any of its Affiliates, a lower rating, or (2) to place
Parent, any of its Affiliates (including any Affiliate that is an issuer of indebtedness) or any securities issued by Parent or any of its Affiliates, on credit watch or negative outlook, in the case of clause (ii) in connection with the
transactions contemplated by this Agreement or as a result of the Merger (as reasonably demonstrated by Parent to the Company). 

  
 76 

 Nothing in this Agreement, including this Section 6.3, shall require,
or be construed to require, Parent, Merger Sub or any of their Affiliates to agree to the sale, license, divestiture, hold separate or other disposition of any assets, categories of assets or businesses or other segments of Parent or Merger Sub or
any of their respective Affiliates (other than the Company and its Subsidiaries). 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. 

(f) Confidentiality. Notwithstanding the foregoing, all information disclosed pursuant to this Section 6.3
shall be subject to the Confidentiality Agreement and nothing in this Section 6.3 shall require any party (i) to violate any of its binding obligations with respect to confidentiality, (ii) to disclose any privileged
information or (iii) to violate any applicable Laws or Orders; provided, that, as applicable, each of the Company and EFIH, on the one hand, and Parent and Merger Sub, on the other hand, shall, to the extent permitted by applicable Law,
provide notice to each other that any information is being withheld pursuant to this provision and shall use their respective commercially reasonable efforts to find a mutually agreeable solution to any such confidentiality and/or privilege
concerns, including providing any such privileged information pursuant to a joint defense agreement. 
 Section 6.4 Access and
Reports. Subject to applicable Law, upon reasonable notice, the Company and EFIH shall (and each shall cause its Subsidiaries (other than the Oncor Entities) to) afford Parent’s officers and other Representatives reasonable access, during
normal business hours throughout the period from the date hereof through the earlier of the Termination Date and the Effective Time, to its employees, properties, books, contracts and records and, during such period, the Company and EFIH shall (and
each shall cause its Subsidiaries (other than the Oncor Entities) to) furnish to Parent all such information concerning its business, properties, facilities, operations and personnel as Parent reasonably requests; provided that, no
investigation pursuant to this Section 6.4 shall (a) unreasonably interfere with the ongoing operations of the Company or its Subsidiaries or (b) affect or be deemed to modify any representation or warranty made by the Company
herein, and provided, further, that the foregoing shall not require the Company or any of its Subsidiaries to (i) permit any inspection, or to disclose any information, that in the reasonable judgment of the Company or such
Subsidiary would result in the disclosure of any trade secrets of third parties or violate any of its or any of its Subsidiaries’ obligations with respect to confidentiality if the Company or such Subsidiary shall have used reasonable best
efforts to furnish such information in a manner that does not result in any such disclosure, including obtaining the consent of such third party to such inspection or disclosure, (ii) disclose any privileged information of the Company or any of
its Subsidiaries if the Company or such Subsidiary shall have used reasonable best efforts to furnish such information in a manner that does not result in the loss of such privilege or (iii) permit any invasive environmental investigation or
sampling, including a Phase II environmental assessment. All information requested pursuant to this Section 6.4 shall be governed by the Confidentiality Agreement. 

  
 77 

 Section 6.5 Publicity. The initial press release or press releases regarding this
Agreement and the transactions contemplated by this Agreement, including the Closing Date Transactions, shall be in a form mutually acceptable to Parent and the Company and thereafter the Company, EFIH and Parent each shall consult with each other
to the extent reasonably practicable prior to issuing any press releases or otherwise making public announcements (except as required by Law) with respect to the Closing Date Transactions. 

Section 6.6 Employee Benefits. 

(a) Pursuant to the Plan of Reorganization or otherwise, the Company and EFIH shall, and shall cause their respective
Subsidiaries to take all such actions within their control as may be necessary, appropriate or desirable to transfer the sponsorship, maintenance and administration of, and all liabilities (and related contracts or agreements with third parties) in
respect of, the Contributed Plans to Reorganized TCEH or its Subsidiaries on or prior to the date of the Reorganized TCEH Spin-Off. As soon as administratively practicable following the Reorganized TCEH Spin-Off, Reorganized TCEH shall transfer the
liabilities related to the post-retirement health, life, dental and vision benefits for participants previously employed by certain discontinued operations of the Company and its Subsidiaries and their predecessors, and the participants’
beneficiaries (identified by employee number) set forth on Schedule 6.6(a) of the Company Disclosure Letter (the “DiscOp OPEB Participants”) and the related accrued benefits liabilities (the “DiscOp OPEB
Liabilities”) from the EFH Retiree Welfare Plan to a new mirror health and welfare plan established by Reorganized TCEH or another plan reasonably acceptable to Parent and the Company (the “New DiscOp OPEB Plan” which such
plan shall be transferred to and assumed by the Company or one of its Subsidiaries prior to or on the Closing Date. For the avoidance of doubt, upon the transfer of the New DiscOp OPEB Plan to the Company or its Subsidiary, the New DiscOp OPEB Plan
(including the DiscOp OPEB Liabilities) shall be an Assumed Plan and the Surviving Company shall indemnify, defend and hold harmless Reorganized TCEH and its Subsidiaries from and against any claim, action, suit, proceeding relating to any
modification or termination of the post-retirement health and life benefits to any DiscOp OPEB Participants on or after the Closing Date. Parent, the Company and Reorganized TCEH shall take all actions necessary to effectuate the transfer of the New
DiscOp OPEB Plan from Reorganized TCEH to Parent or Company as soon as administratively practicable following the establishment of such plan, but in any event prior to the Closing Date. Notwithstanding anything in this Agreement to the contrary,
during the period beginning on the Reorganized TCEH Spin-Off date and ending on the date the New DiscOp OPEB Plan is assumed by the Company or its Subsidiary as set forth in this Section 6.6, the Company, Surviving Company or its
Subsidiaries shall reimburse Reorganized TCEH and its Affiliates for all claims incurred by DiscOp OPEB Participants under the EFH Retiree Welfare Plan or New DiscOp OPEB Plan, as applicable, plus any reasonable out of pocket expenses incurred by
Reorganized TCEH and its Affiliates in providing such benefits. Notwithstanding the foregoing, except as otherwise provided herein (including, without limitation, the Assumed Plans) or in the 

  
 78 

 
Split Participant Agreement (as defined below), none of Parent, any Oncor Entity or any of their Affiliates shall assume or otherwise incur any liability or obligation under any compensatory,
severance or similar arrangement in respect of any Non-Oncor Employee (as defined below), it being understood that Reorganized TCEH and Oncor shall enter into the Split Participant Agreement. For purposes of Section 6.6(a): 

“Non-Oncor Employee” means consistent with past practices (i) any individual employed by the Company,
EFIH, TCEH, Reorganized TCEH or any of their respective Affiliates (other than the Oncor Entities) on or immediately following the Reorganized TCEH Spin-Off or (ii) any individual formerly employed by TCEH or any Affiliate of TCEH or
Reorganized TCEH (which for this purpose would constitute an Affiliate immediately following the Closing Date), other than an Oncor Employee; 

“Oncor Employee” means consistent with past practices (i) any individual employed by an Oncor Entity on
or immediately following the Closing Date or (ii) any individual formerly employed by an Oncor Entity or, by any predecessor regulated electric utility business on a full time basis, who terminated employment with and did not subsequently
become employed by a non-Oncor Entity; and 
 “Split Participant Service” means service of Oncor Employees
or Non-Oncor Employees, as applicable, whose employment includes service with both the Oncor Entities (or a predecessor regulated electric business) and a business of the Company or its Affiliates other than the Oncor Entities. 

(b) EFIH, the Company and Parent shall use commercially reasonable efforts to obtain unconditional bankruptcy court approval
authorizing the termination and distribution of all payments and obligations under the Discharged Plans (other than any such Discharged Plans that are equity based plans or the Ebasco Services of Canada Limited Pension Plan) prior to the effective
date of the Plan of Reorganization under which the Non-Qualified Plans are to be discharged; provided, however, if EFIH, the Company and Parent cannot obtain such unconditional bankruptcy court approval prior to such date, such Discharged Plans will
be terminated as the effective date of the Plan of Reorganization under which the Non-Qualified Plans are to be discharged and paid out and all associated liabilities discharged in accordance with the terms and procedures of such Plan of
Reorganization. 
 (c) Prior to the Closing Date, Oncor and Reorganized TCEH (or Opco (as defined in the Separation
Agreement)) shall execute and deliver a Split Participant Agreement substantially in the form attached hereto as Exhibit F (the “Split Participant Agreement”). 

(d) No provision of this Agreement shall obligate Parent or the Company or any of its Subsidiaries or Affiliates to continue
the employment of any employee of the Company or any of its Subsidiaries (other than the Oncor Entities) after the Closing Date. 

  
 79 

 (e) The Company and Parent agree to cooperate in good faith using commercially
reasonable efforts to minimize the risk of any Contributed Plan and Assumed Plan becoming a “multiple employer plan” (within the meaning of Section 413 of the Code) or “multiple employer welfare plan” (within the meaning of
Section 3(40) of ERISA) following the Closing Date. 
 (f) The Company and Parent agree to work together in good faith
to develop such timelines, plans, agreements, and communications, and to exchange such information as is necessary to effectuate the intent of this Section 6.6 in an orderly manner. 

(g) For a period of ninety (90) days immediately following the Closing Date, neither Parent nor the Surviving Company
shall close any facility or lay off any Employees of the Surviving Company or its Subsidiaries, if such closure or layoff would result in any material obligations or liabilities for Reorganized TCEH. 

(h) The provisions of this Section 6.6 are solely for the benefit of the parties to this Agreement, and no current
or former Employee or any other individual associated therewith shall be regarded for any purpose as a third party beneficiary of this Agreement, and nothing herein shall be (i) construed as an amendment to any Benefit Plan for any purpose, or
(ii) give any employee or former employee or any other individual associated therewith or any employee benefit plan or trustee thereof or any other third person any right to enforce the provisions of this Section 6.6 or
(iii) obligate Parent, the Merger Sub, Reorganized TCEH or any of their respective Affiliates to (A) maintain any particular benefit plan or refrain from amending or terminating any benefit plan, except as provided otherwise in the Split
Participant Agreement or (B) retain the employment of any particular employee. 
 Section 6.7 Expenses. The Surviving
Company shall pay all charges and expenses, including those of the Exchange Agent, in connection with the transactions contemplated in Article IV. Except as otherwise provided in Section 6.3, Section 6.18,
Section 6.19, Section 6.20 and Section 6.22 or any administrative expenses of the Debtors’ estates addressed in the Plan of Reorganization, whether or not the Merger is consummated, all costs and expenses
incurred in connection with this Agreement and the Closing Date Transactions and the other transactions contemplated by this Agreement shall be paid by the party incurring such expense. 

Section 6.8 Indemnification; Directors’ and Officers’ Insurance. 

(a) From and after the Effective Time for a period of six (6) years, the Surviving Company agrees that it will indemnify
and hold harmless, to the fullest extent permitted under applicable Law (and the Surviving Company shall also advance expenses as incurred to the fullest extent permitted under applicable Law, provided that, the Person to whom expenses are
advanced provides an undertaking to repay such advances if it is ultimately determined that such Person is not entitled to indemnification), each present and former director, manager and officer of the Company and each of its Subsidiaries (together,
the “Indemnified Parties”) against any costs or expenses (including reasonable and necessary attorneys’ fees and experts’ fees), and sums which an Indemnified Party 

  
 80 

 
becomes legally obligated to pay solely as a result of judgments, fines, losses, claims, damages, settlements or liabilities (collectively, “Costs”) arising out of any claim,
action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or related to such Indemnified Parties’ service as a manager, director or officer of the Company or any of its Subsidiaries or
other services performed by such persons at the request of the Company or any of its Subsidiaries at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, including the transactions contemplated by
this Agreement; provided, however, that the Surviving Company shall not indemnify any Indemnified Party for any Costs brought about or contributed to in fact by fraudulent act by such Indemnified Party; and provided, further, that the
Surviving Company shall not be obligated to reimburse any Indemnified Party for any Costs unless and until such Indemnified Party has exhausted the limits of recovery from any other Person obligated to indemnify and reimburse such Indemnified Party
(unless the Company has agreed otherwise in writing prior to the date hereof with any such other Person, in which case this proviso shall be limited with respect to such other Person to the extent of such agreement). 

(b) Prior to the Effective Time, the Company shall obtain, effective as of the Effective Time, and fully pay the premium for a
run-off of (i) the Company’s and its Subsidiaries’ existing directors’, managers’ and officers’ insurance policies as of the date hereof, and (ii) the Company’s existing fiduciary liability insurance policies
as of the date hereof, in each case for a claims reporting or discovery period of at least six (6) years from and after the Effective Time with respect to any claim based on alleged acts or omissions occurring during any period of time at or
prior to the Effective Time (it being understood that, with respect to any claim arising from actual or alleged acts or omissions of such Persons in their capacity as a current or former director or officer or other Representative of any of TCEH
Companies or the SpinCo Group (each as defined in the Separation Agreement), such period shall be limited to the period on or prior to the TCEH Effective Date) from an insurance carrier with the same or better credit rating as the Company’s
current insurance carrier with respect to directors’ and officers’ liability insurance and fiduciary liability insurance (collectively, “D&O Insurance”) with terms, conditions, retentions and limits of liability that
are no less advantageous than the coverage provided under the Company’s existing policies with respect to any actual or alleged error, misstatement, misleading statement, act, omission, neglect, breach of duty or any matter claimed against a
current or former director or officer or other Representative of the Company or any of its Subsidiaries by reason of him or her serving in such capacity that existed or occurred at or prior to the Effective Time (including in connection with this
Agreement and the transactions or actions contemplated by this Agreement). If the Company, after its good faith efforts to obtain, is unable to obtain such run-off insurance policies as of the Effective Time, the Surviving Company shall, and Parent
shall cause the Surviving Company to, continue to maintain in effect for a period of at least six (6) years from and after the Effective Time the D&O Insurance in place as of the date hereof with terms, conditions, retentions and limits of
liability that are no less advantageous than the coverage provided under the Company’s existing policies as of the date hereof, or the Surviving Company shall, and Parent shall cause the Surviving Company to, use reasonable best efforts to
purchase comparable D&O Insurance for such six-year period with terms, conditions, retentions and limits of liability that are at least as 

  
 81 

 
favorable as provided in the Company’s existing policies as of the date hereof; provided, however, that in no event shall Parent or the Surviving Company be required to
expend for such policies pursuant to this sentence an annual premium amount in excess of 200% of the annual premiums currently paid by the Company for such insurance; and provided, further, that if the annual premiums of such insurance
coverage exceed such amount, the Surviving Company shall obtain a policy with the greatest coverage available for a cost not exceeding such amount. 

(c) If the Surviving Company or any of its successors or assigns shall (i) consolidate with or merge into any other
corporation or entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfer all or substantially all of its properties and assets to any individual, corporation or other entity,
then, and in each such case, proper provisions shall be made so that the successors and assigns of the Surviving Company shall assume all of the obligations set forth in this Section 6.8. 

(d) The provisions of this Section 6.8 are intended to be for the benefit of, and shall be enforceable by, each of
the Indemnified Parties. 
 (e) The rights of the Indemnified Parties under this Section 6.8 shall be in addition
to any rights such Indemnified Parties may have under the certificate of incorporation or formation or bylaws, operating agreement or comparable governing documents of the Company or any of its Subsidiaries, or under any applicable Contracts or
Laws. All rights to indemnification and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time and rights to advancement of expenses relating thereto now existing in favor of any Indemnified Party as provided
in the certificate of formation, bylaws, operating agreement or comparable governing documents of the Company or any of its Subsidiaries or any indemnification agreement between such Indemnified Party and the Company or any of its Subsidiaries shall
be continued or be assumed by the Surviving Company following the Merger and shall not be amended, repealed or otherwise modified in any manner that would adversely affect any right thereunder of any such Indemnified Party for a period of six
(6) years after the Effective Time. 
 Section 6.9 Resignation of Directors and Officers. Pursuant to the Plan of
Reorganization, except as otherwise may be agreed by Parent in writing, the Company Board, all officers of the Company and all members of any board of directors or similar governing body and all officers of any Subsidiary of the Company (other than
the Oncor Entities), in each case who are in office immediately prior to the Effective Time, shall be deemed to have resigned from such position(s) effective at the Effective Time. In addition, immediately prior to the Effective Time, EFIH shall
cause the Member Directors (as defined in the Oncor Holdings LLC Agreement) to resign and shall provide to the boards of directors of Oncor Holdings and Oncor EFIH’s written consent to the resignation of the Independent Directors (as defined in
the LLC Agreements) of each of Oncor Holdings and Oncor. 

  
 82 

 Section 6.10 Bankruptcy Court Matters. The Company and EFIH shall comply with the
following covenants and agreements contained in the Plan Support Agreement as if such covenants and agreements were set forth herein, solely to the extent they affect the rights of Parent or Merger Sub: Section 3, Sections 4.02(a) and Sections
7.02 through and including 7.05. 
 Section 6.11 Listing and SEC Registration. Parent shall use its best efforts to cause
(i) the shares of Parent Common Stock issuable pursuant to this Agreement to be approved for listing on the NYSE, subject to official notice of issuance, and (ii) all state securities or “blue sky” authorizations to have been
received, in each case, as promptly as practicable after the date of the entry of the EFH Confirmation Order, and in any event prior to the Closing Date. Prior to the Closing Date, Parent shall use its best efforts to seek a “no-action”
letter from the SEC seeking confirmation that the issuance of the Parent Common Stock pursuant to this Agreement is exempt from the registration requirements of the Securities Act and from applicable state securities laws, pursuant to
Section 1145 of the Bankruptcy Code. Notwithstanding the foregoing, prior to seeking the “no-action” letter (or any amendment or supplement thereto) or responding to any comments of the SEC with respect thereto, Parent
(i) shall provide the Company and EFIH an opportunity to review and comment on such document or response (including the proposed final version of such document or response) and (ii) shall consider in good faith all comments reasonably
proposed by the Company or EFIH. In the event that the staff of the SEC does not issue a favorable “no action” letter with respect to the application of Section 1145 of the Bankruptcy Code in connection with the issuance described
above, (a) Parent shall use it best efforts to, as applicable, cause the shares of Parent Common Stock issuable pursuant to this Agreement to be registered with the SEC on Form S-4 or other applicable registration statement on or before the
Closing Date and (b) Parent and the Company shall each use its reasonable best efforts to cause all of the information supplied by it or any of its Subsidiaries (other than the Oncor Entities) for inclusion or incorporation by reference into
the Form S-4 or other applicable registration statement at the time such registration statement becomes effective under the Securities Act, not to contain any untrue statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein, in light of the circumstances under which they are made, not misleading. 

Section 6.12 Parent and Merger Sub Waiver. Subject to the receipt by Parent, Merger Sub, the Company and EFIH of a reciprocal
release from Reorganized TCEH and its Subsidiaries pursuant to the Plan of Reorganization which is substantially consistent with the release contained herein, except as set forth in Section 6.12 of the Parent Disclosure Letter, each of
Parent, Merger Sub, the Company and EFIH, acknowledges and agrees that, effective from and after the Closing, to the fullest extent allowed by Law, Reorganized TCEH and any of its Subsidiaries and their respective directors, employees, managers,
equityholders, successors and assigns (the “TCEH Released Persons”) shall be deemed released and discharged by Parent, Merger Sub, the Company and EFIH, and each of their respective Subsidiaries from any and all Claims and causes of
action, Debts, liabilities and obligations, of any nature, whether known or unknown, in law or equity, including any derivative claims, asserted on behalf of the E-Side Debtors, that Parent, Merger Sub, the Company and EFIH, and each of their
respective Subsidiaries would have been legally entitled to assert in their own right before the effectiveness of such release (whether individually or collectively) or on behalf of the holder of any Claim or Interest (the “TCEH Released
Claims”), and except for obligations issued or required to be paid pursuant to the Plan of Reorganization, all entities that have held, hold, or may hold TCEH Released Claims are permanently enjoined, from and after the Closing Date, from
taking any of the following actions against the TCEH Released Persons: (i) commencing or continuing in any 

  
 83 

 
manner any action or other proceeding of any kind on account of or in connection with or with respect to any such claims or interests; (ii) enforcing, attaching, collecting, or recovering by
any manner or means any judgment, award, decree, or order against such entities on account of or in connection with or with respect to any such claims or interests; (iii) creating, perfecting, or enforcing any lien or encumbrance of any kind
against such entities or the property or the estates of such entities on account of or in connection with or with respect to any such claims or interests; (iv) asserting any right of setoff, subrogation, or recoupment of any kind against any
obligation due from such entities or against the property of such entities on account of or in connection with or with respect to any such claims or interests unless such entity has timely asserted such setoff right in a document filed with the
Bankruptcy Court explicitly preserving such setoff, and notwithstanding an indication of a claim or interest or otherwise that such entity asserts, has, or intends to preserve any right of setoff pursuant to applicable law or otherwise; and
(v) commencing or continuing in any manner any action or other proceeding of any kind on account of or in connection with or with respect to any such claims or interests released or settled pursuant to the Plan of Reorganization. Subject to the
receipt by Parent, the Surviving Company and EFIH of a reciprocal indemnity from Reorganized TCEH and its Subsidiaries pursuant to the Plan of Reorganization which is substantially consistent with the indemnity contained herein, each of Parent, the
Surviving Company and EFIH hereby agrees, on behalf of itself, effective from and after the Closing, to indemnify and hold harmless each of the TCEH Released Persons from and against, and in respect of, any and all losses, liabilities, damages,
obligations, costs or expenses (including reasonable legal fees) incurred by or on behalf of any TCEH Released Person as a result of such entity’s violation of this Section 6.12. 

Section 6.13 Tax-Free Reorganization Treatment. The parties to this Agreement intend that the Merger will qualify as a
reorganization under Section 368(a) of the Code, and each shall not, and shall not permit any of its respective Subsidiaries or controlled Affiliates (other than the Oncor Entities) to take any action, or fail to take any action, that would
reasonably be expected to jeopardize the qualification of the Merger as a reorganization under Section 368(a) of the Code. 

Section 6.14 Tax 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). 

  
 84 

 (b) Supplemental Ruling. The Company shall be responsible for the
preparation and filing with the IRS of one or more supplemental ruling requests 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 I (such request, the “Supplemental Ruling Request,” the rulings granted pursuant to thereto, the “Supplemental Rulings,” and the materials to be filed in respect of the Supplemental Ruling Request,
the “Supplemental 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 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 Initial Private Letter Ruling
(other than with respect to the effect of the Merger) if the Company determines, in its reasonable discretion, that making such supplement, modification, or request could result in any delay in obtaining the Supplemental Ruling or be otherwise
detrimental to the process of obtaining the Supplemental Ruling. The parties hereto 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 (i) 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, (A) all scheduled conference calls and in-person meetings, to the extent a Representative of the TCEH First Lien Creditors or Reorganized TCEH is given the opportunity to participate in such communications, conference
calls, or in-person meetings; and (ii) updated 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 

  
 85 

 
in the Supplemental Ruling Requests (including, for the avoidance of doubt, the requested rulings, if any, that are not Fundamental Rulings described on Exhibit I), 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, and 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 (x) a material economic detriment to Parent or the Company or any of their respective Subsidiaries (y) the issuance of common stock by Parent
or its Affiliates, if requested by the IRS in order to issue reasonably satisfactory Supplemental Rulings. 
 (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. 
 (f) Tax Matters Agreement. Prior to, but
contingent upon the Reorganized TCEH Spin-Off, the Company and Reorganized TECH shall duly execute and deliver a Tax Matters Agreement substantially in the form of Exhibit G (the “Tax Matters Agreement”), in accordance with
the Plan of Reorganization. 
 Section 6.15 Registration Rights. To the extent that any recipients of any Parent Common Stock
pursuant to this Agreement would become or continue to be affiliates of Parent for purposes of Rule 144 under the Securities Act as a result of receipt of such Parent Common Stock, Parent shall provide such recipients customary registration rights
pursuant to a registration rights agreement effective as of the Effective Time reasonably satisfactory to the Company. 
 Section 6.16
Transition Services Agreement; Separation Agreement. At the Closing, the Company and Reorganized TCEH shall duly execute and deliver a Transition Services Agreement substantially in the form of Exhibit H (the “Transition
Services Agreement”). Prior to, but contingent upon the Reorganized TCEH Spin-Off, the Company and Reorganized TCEH and Opco (as defined in the Separation Agreement) shall duly execute and deliver a Separation Agreement (the
“Separation Agreement”) substantially in the form of Exhibit J, in each case in accordance with the Plan of Reorganization. Following the execution of the Separation Agreement, the Company shall (i) use its reasonable
best efforts to comply with its covenants and other obligations thereunder, and (ii) enforce its rights and remedies thereunder in the event of a breach by Reorganized TCEH or Opco. 

Section 6.17 Notice of Current Events. From and after the date of this Agreement until the Effective Time, the Company and Parent
shall promptly notify each other orally and in writing upon becoming aware of any (i) occurrence, or non-occurrence, of any event that, individually or in the aggregate, would reasonably be expected to cause any condition to the obligations of
the other party to effect the Closing not to be satisfied; (ii) written notice from any third party (other than a notice that has been previously identified pursuant to the Company Disclosure Letter) alleging that the consent of such party is
or may be required in connection 

  
 86 

 
with the Closing Date Transactions or the other transactions contemplated by this Agreement or the Plan of Reorganization; and (iii) written notice of any proceeding commenced or, to the
Knowledge of the Company or Parent, threatened against the Company, Parent or their respective Subsidiaries (other than the Oncor Entities), that has had or would have, individually or in the aggregate, a Company Material Adverse Effect or a Parent
Material Adverse Effect; provided, however, that in each case the delivery of any notice pursuant to this Section 6.17 shall not cure any breach of any representation or warranty requiring disclosure of such matter prior to
the date of this Agreement or otherwise limit or affect the remedies available hereunder to either Party, and the failure to deliver any such notice shall not affect any of the conditions set forth in Article VII. 

Section 6.18 Drag-Along Rights. 

(a) Each of the parties hereto acknowledges and agrees that the Offer (together with this Agreement to the extent referred to
therein) constitutes an offer by Parent and Merger Sub to purchase (i) all of the LLC Units in Oncor held indirectly by the Company and (ii) all of the LLC Units in Oncor that are owned by Oncor Management and by TTI as provided for in
Section 3.3(a) of the Investor Rights Agreement. 
 (b) So long as Parent and Merger Sub have not (x) rescinded the
Offer or (y) amended or modified the Offer in a manner that violates the Investor Rights Agreement, at any time following the receipt of a written request from Parent and prior to the Termination Date, the Company shall (i) prepare a
Required Sale Notice (as such term is defined in the Investor Rights Agreement) in form and substance reasonably satisfactory to Parent and the Company and consistent with Section 3.3 of the Investor Rights Agreement and the terms of this
Agreement and (ii) promptly deliver such Required Sale Notice to TTI. 
 (c) Notwithstanding anything to the contrary in
Section 6.7, all reasonable out-of-pocket Costs incurred by the Company or any of its Subsidiaries (including those of its Representatives) after the date of this Agreement in connection with (i) this Section 6.18,
(ii) the Offer or (iii) delivery of the Required Sale Notice to TTI, shall be paid, or reimbursed, by Parent in immediately available funds within thirty (30) days after termination of this Agreement in accordance with its terms
(1) except if the Company or EFIH terminate this Agreement pursuant to Section 8.3(e) or Section 8.3(f), in which event no amounts shall be payable by Parent, and (2) other than any Costs arising from a material
breach by the Company or EFIH of its obligations under this Agreement (including under this Section 6.18 and Section 6.19) with respect to such matters or from the gross negligence or willful misconduct of the Company or EFIH
in connection with such matters. 
 (d) Parent shall indemnify and hold harmless the Company, its Subsidiaries and its and
their respective Representatives from and against any and all Costs suffered or reasonably incurred by them in connection with (i) this Section 6.18, (ii) the Offer, or (iii) the Required Sale Notice, other than any Costs
arising from a material breach by the Company or EFIH of its respective obligations under this Agreement (including under this Section 6.18 and Section 6.19) with respect to such matters or the gross negligence or willful
misconduct of the Company or EFIH in connection with such matters. 

  
 87 

 (e) Parent and Merger Sub shall be responsible for their own Costs in connection
with (i) this Section 6.18, (ii) the Offer or (iii) delivery of the Required Sale Notice to TTI. 

Section 6.19 Enforcement of Certain Investor Rights. 

(a) Following the execution of this Agreement, Parent and Merger Sub shall use reasonable efforts to negotiate and execute
definitive documentation with TTI (or, if applicable, its equityholders) providing for the acquisition of the Minority Interest as of the Closing Date for consideration in an amount sufficient to satisfy the applicable requirements of
Section 3.3 of the Investor Rights Agreement and otherwise on terms to be mutually agreed by Parent, Merger Sub and TTI (or, if applicable, its equityholders). Solely to the extent that, at any time after the date that is thirty (30) days
from the date on which the Required Sale Notice is delivered in accordance with Section 6.18, (x) neither Merger Sub nor any of its Affiliates has executed definitive documentation with TTI (or, if applicable, its equityholders)
providing for the acquisition of the Minority Interest, (y) Merger Sub and Parent have complied, in all material respects, with their obligations under this Section 6.19(a) and (z) Parent and Merger Sub have
neither rescinded the Offer nor amended or modified the Offer in a manner that violates the Investor Rights Agreement, Parent or Merger Sub shall be entitled to send a written notice to the Company requesting that the Company commence an
Enforcement Action (as defined below). The parties hereto hereby agree that Parent and Merger Sub shall have complied with their respective obligations under this Section 6.19(a) to the extent Parent, Merger Sub or an Affiliate of Parent
has made and not rescinded a good faith offer to TTI consistent with the Offer and otherwise made good faith efforts to propose the basis for negotiations and propose draft definitive documentation providing for the acquisition of the Minority
Interest as of the Closing Date consistent with the terms of the Offer and the Investor Rights Agreement. 
 (b) Promptly
following, and in no case more than fourteen (14) Business Days after, the delivery of the written notice described in Section 6.19(a), the Company shall file an action (the “Enforcement Action”) in the Bankruptcy
Court (or, if the Bankruptcy Court issues a final order confirming that it does not have jurisdiction over the Enforcement Action, another appropriate court mutually agreed in good faith by the Company and Parent) that seeks any or all of the
following remedies (as determined by consultation among the parties hereto, but including, at a minimum, the remedies described in clauses (i) and (ii) below): (i) a determination that the Company has the right to enforce the
Drag-Along Rights and TTI is accordingly bound to consummate the sale of the Minority Interest at the Closing, (ii) a determination that TTI is obligated to take such actions as may be reasonably required on its part in connection with
consummating the IPO Conversion Plan (provided the Company shall not be required to file an Enforcement Action including this remedy if the Company, based on the advice of outside counsel, reasonably determines that an actual case or
controversy regarding such obligation does not exist at that time; provided further, that if TTI indicates that it will 

  
 88 

 
not comply with its obligations in connection with the IPO Conversion within thirty (30) days of delivery of the Required Sale Notice any temporal requirement for a case or controversy
to exist shall be deemed to be satisfied, (iii) a determination, if applicable, that TTI has failed to comply with its obligations under the Investor Rights Agreement with respect to the Drag-Along Rights contained therein or with respect to
the IPO Conversion Plan, (iv) enforcement of any other obligations of TTI arising under the Investor Rights Agreement or the Oncor LLC Agreement, in each case solely relating to the matters described in clause (i) and/or (ii) above
and (v) any other remedy available to the Company at law or in equity in connection with such matters. For the avoidance of doubt, the Company shall have no obligation to bring any other action (whether in law, equity or otherwise) against TTI
pursuant to this Section 6.19; provided, however, that, to the extent that TTI or any of its Affiliates commences any action relating to the matters identified in this Section 6.19 against the E-Side Debtors or any of
their Affiliates, the Company or such other Person shall as promptly as practicable seek to remove any such action to the Bankruptcy Court and, to the extent applicable, seek to enforce the automatic stay against such action pending removal. 

(c) The Enforcement Action shall be conducted by the Company with counsel selected by the Company, in its reasonable
discretion, which may include Kirkland & Ellis LLP. To the extent that Parent and/or Merger Sub move to intervene in and otherwise participate in the Enforcement Action, at their own cost and expense and with their own counsel (which may
include Chadbourne & Parke LLP), the Company and EFIH shall not oppose such motion, or knowingly take any action with the intent of preventing, restricting or hindering Parent or Merger Sub from intervening and participating in the
Enforcement Action, and shall support the their right to intervene in the Enforcement Action for any and all purposes related to the Enforcement Action (including related counterclaims) with full rights of participation. 

(d) To the extent that, after the commencement of the Enforcement Action, (i) none of Merger Sub or any of its Affiliates
has executed definitive documentation with TTI (or, if applicable, its equityholders) providing for the acquisition of the Minority Interest, (ii) Parent and Merger Sub have complied, in all material respects, with their obligations under
Section 6.19 and (iii) Merger Sub has neither rescinded the Offer nor amended or modified the Offer in a manner that violates the Investor Rights Agreement, the Company shall prosecute the Enforcement Action diligently until
entry of a final order resolving the Enforcement Action in its entirety. Subject to the terms of this Section 6.19, the Company and Parent shall (and shall cause their respective attorneys and advisors to) cooperate with each other and
use reasonable best efforts to take all actions, and do, or cause to be done, all things reasonably necessary or advisable to achieve a Successful Outcome (as defined below) of the Enforcement Action, including preparing and filing all documentation
reasonably required in connection therewith. A “Successful Outcome” means obtaining the applicable remedies referred to in clauses (i) through (iv) of Section 6.19(b) or entering into a settlement or compromise
of the Enforcement Action as set forth in Section 6.19(f). 

  
 89 

 (e) In connection with the Enforcement Action, the Company and EFIH shall
(i) provide Parent, Merger Sub and their designated advisors with a reasonable opportunity to review in advance and provide comments to any material filings made in connection therewith, and consider those comments in good faith,
(ii) reasonably consult with, and consider in good faith the views of, Parent, Merger Sub and their designated counsel in connection with the prosecution, defense and/or settlement of such Enforcement Action and (iii) allow Parent, Merger
Sub and their designated legal advisors to attend, and, if permitted by applicable Law (and only if appropriate agreements are entered into designed to minimize the risk of waiving, and with the intention of maintaining, any privilege or work
product doctrine), participate in, all material meetings, communications and proceedings with respect to such Enforcement Action. Without limitation to the foregoing sentence, the Company shall consult with, and consider in good faith the views of,
Parent and Merger Sub regarding all material strategic decisions relating to the conduct of the Enforcement Action, and Parent shall be entitled to set the timing for the filing of any summary judgment or other dispositive motion and for any trial
or other significant hearing; provided, however, that notwithstanding anything to contrary in this Section 6.19, the Company shall be entitled to refrain from taking any action proposed by Parent that it reasonably determines
(based on the advice of its counsel) is (A) likely to have a material and adverse effect on the ability of the Company and/or EFIH to effectuate the Closing Date Transactions or the other transactions contemplated hereby or in the Plan of
Reorganization, or (B) inconsistent with its board of directors’ applicable fiduciary duties. Subject to the limitations set forth in the first sentence of Section 6.19(d), the Company shall, and shall direct its counsel to,
use reasonable best efforts to take all steps to prosecute the Enforcement Action as promptly as reasonably practicable, including filing motions with the court, as appropriate, to seek a ruling on expedited treatment for the Enforcement Action, and
Parent (including designated legal counsel and other advisors) shall use its and their reasonable best efforts to support and assist the Company in fulfilling its obligations with respect to the Enforcement Action. 

(f) Without limiting any other provision of this Section 6.19, the Company shall not settle or compromise any
Enforcement Action or consent to the entry of any order in connection therewith without the prior written consent of Parent (in its sole discretion). Parent shall be entitled to cause the Company to settle or compromise any Enforcement Action or
consent to the entry of any order in connection therewith without the consent of the Company so long as (i) any such settlement or compromise, and any payment obligations in connection therewith, shall be contingent on the occurrence of the
Closing and (ii) Parent provides advance notice of at least five (5) Business Days to the Company of the proposed terms of such settlement or compromise and the Company does not notify Parent in writing within such five (5) Business
Day period that the Company has reasonably determined (based on the advice of its counsel) that such settlement or compromise (A) is likely to have a material and adverse effect on the ability of the Company and/or EFIH to effectuate the
Closing Date Transactions or the other transactions contemplated hereby or in the Plan of Reorganization, or (B) is inconsistent with its board of directors’ applicable fiduciary duties. 

  
 90 

 (g) The Company shall cause its counsel to track separately all fees and expenses
incurred in connection with the Enforcement Action as part of its ongoing fee application process. Notwithstanding anything to the contrary in Section 6.7, the Company shall invoice Parent for all reasonable and documented fees and
expenses incurred by it and its Affiliates in connection with the Enforcement Action on a monthly basis and such invoices shall be payable by Parent in immediately available funds within thirty (30) days after termination of this Agreement in
accordance with its terms (except if the Company or EFIH terminate this Agreement pursuant to Section 8.3(e) or Section 8.3(f), in which event no amounts shall be payable by Parent). 

(h) In addition, Parent shall indemnify and hold harmless the Company, its Affiliates and its and their respective
Representatives from and against any and all Costs suffered or reasonably incurred as a result of actions taken pursuant to this Section 6.19, to the extent such actions are taken during the period from the date of this Agreement to its
termination in accordance with it terms except if this Agreement is terminated pursuant to Section 8.3(e) or Section 8.3(f) and other than any Costs arising from a material breach by the Company or EFIH of its respective
obligations under this Section 6.19 or from the gross negligence or willful misconduct of the Company in connection with the Enforcement Action. 

(i) If requested by Parent, the Company, EFIH and their respective advisors shall promptly consent to, execute and deliver to
Parent a mutually agreeable common interest or joint defense or prosecution agreement regarding the defense and/or prosecution of any Enforcement Action that is consistent with the foregoing provisions of this Section 6.19. For purposes
of this Agreement, the term “Enforcement Action” shall include any appeals therefrom. 
 Section 6.20 IPO Conversion
Plan. 
 (a) The Company hereby agrees that it shall (i) reasonably promptly (but in no event later than ten
(10) Business Days) following the receipt of the Approval Order, approve the IPO Conversion Plan, (ii) reasonably promptly (but in no event later than ten (10) Business Days) following written request of Parent, deliver notice to
Oncor of the Company’s intent to undertake the IPO Conversion pursuant to the IPO Conversion Plan (the “IPO Conversion Plan Notice”) and (iii) undertake the steps of the IPO Conversion Plan reasonably requested by Parent.

 (b) Notwithstanding anything to the contrary in Section 6.7, all reasonable out-of-pocket Costs incurred by
the Company or any of its Subsidiaries (including those of its Representatives) after the date of this Agreement in connection with (i) this Section 6.20, (ii) the IPO Conversion Plan or (iii) delivery of the IPO
Conversion Plan Notice to Oncor, shall be paid, or reimbursed, by Parent in immediately available funds within thirty (30) days of the termination of this Agreement in accordance with its terms (except if the Company or EFIH terminate this
Agreement pursuant to Section 8.3(e) or Section 8.3(f), in which event no amounts shall be payable by Parent and other than any Costs arising from a material breach by the Company or EFIH of its respective obligations under
this Agreement (including under Section 6.19 and this Section 6.20) or the gross negligence or willful misconduct of the Company or EFIH in connection with such matters. Parent and Merger Sub shall be responsible for their
own Costs in connection with (i) this Section 6.20, (ii) the IPO Conversion Plan or (iii) delivery of the IPO Conversion Plan Notice to Oncor. 

  
 91 

 (c) Parent shall indemnify and hold harmless the Company, its Subsidiaries and
its and their respective Representatives, if this Agreement is terminated in accordance with its terms from and against any and all Costs suffered or reasonably incurred by them in connection with (i) this Section 6.20,
(ii) the IPO Conversion Plan, or (iii) delivery of the IPO Conversion Plan Notice to Oncor, other than any Costs arising from a material breach by the Company or EFIH of its respective obligations under this Agreement (including under
Section 6.19 and this Section 6.20) or from the gross negligence or willful misconduct of the Company or EFIH in connection with such matters. 

Section 6.21 Oncor Entities. 

(a) Each of the Company and EFIH covenants that it will exercise its rights to consent and vote (if any) under the Oncor
Agreements as direct or indirect equity owners of the Oncor Entities in a manner intended to cause the Oncor Entities to comply with each of their respective covenants and agreements set forth in the Oncor Letter Agreement, the Investor Rights
Agreement and under applicable Law. Notwithstanding the foregoing, Parent and Merger Sub acknowledge and agree that neither the Company nor EFIH shall be required, in connection with such party’s obligations under this Section 6.21,
and their reasonable best efforts shall not include any obligation, to (A) pay any amounts to the Oncor Entities or any other Person or incur any liabilities or other obligation, (B) execute or enter into or perform any new agreement
(other than an agreement contemplated hereby or in the Plan of Reorganization or that confirms or makes effective its obligations hereunder), or (C) breach any Law or commence any Action against any Person, including any of the Oncor Entities
or their respective officers and managers, other than the Enforcement Action. 
 (b) Each of the Company and EFIH shall, and
shall cause each of their respective Subsidiaries to not permit Oncor Holdings to take, or permit Oncor to take, any of the actions set forth in the Oncor Holdings LLC Agreement or the Oncor LLC Agreement, in each case that require the approval or
consent of the Company or any of its Subsidiaries. 
 Section 6.22 Financing. 

(a) Prior to the date hereof, Parent has provided the Company with a description of the potential debt financing (the
“Debt Financing”) and equity financing (the “Equity Financing” and together with the Debt Financing, the “Financing”) it may incur in order to raise proceeds sufficient to consummate the
transactions contemplated by this Agreement. Prior to the earlier of the Closing Date and the Termination Date, the Company agrees to use reasonable best efforts to provide, and to use reasonable best efforts to cause its Subsidiaries (other than
Oncor Entities, subject to Section 6.21) and their respective officers and employees to provide, reasonable cooperation in connection with the arrangement of the Financing; provided that, Parent shall use reasonable best

  
 92 

 
efforts to provide the Company with notice of any information needed by Parent as soon as reasonably practicable. The Company’s reasonable best efforts contemplated by this
Section 6.22 include the following: (i) assisting with the preparation of customary materials for rating agencies and rating agency presentations, offering documents, private placement memoranda, bank information memoranda,
prospectuses and similar documents required in connection with the Financing, together with procuring customary authorization letters authorizing the distribution of information to prospective lenders or investors (which customary authorization
letters shall be required notwithstanding the reasonable best efforts standard required of the Company above); (ii) furnishing (x) all information and data reasonably requested by Parent to prepare all pro forma financial statements
customary in connection with the Financing and (y) all financial statements and financial data of the type and form prepared in accordance with Regulation S-X and Regulation S-K under the Securities Act for offerings of debt or equity
securities on a registration statement on Form S-1 or Form S-3 under the Securities Act (which, for the avoidance of doubt, in no event shall require financial information otherwise required by Rule 3-10 and Rule 3-16 of Regulation S-X
(provided that information with respect to assets, liabilities, revenue and EBITDA with respect to non-guarantors in the aggregate shall be provided) or “segment reporting” and any Compensation Discussion and Analysis or executive
compensation information required by Item 402 of Regulation S-K)) to the extent customary to consummate the Financing, including all information required to be incorporated therein (subject to exceptions customary for a private Rule 144A
offering); (iii) furnishing Parent and the lenders and investors for such Financing or their respective Affiliates promptly, and in any event no later than three (3) Business Days prior to an Early Financing Date (as defined below) or the
Closing Date, as applicable, with all documentation and other information which any lender or investor providing or arranging the Financing has reasonably requested, including under applicable “know your customer” and anti-money laundering
rules and regulations, including the PATRIOT Act in each case to the extent such request is made at least ten (10) Business Days prior to the Early Financing Date or the Closing Date, as applicable; (iv) providing customary management
representation letters to the independent accountants and using reasonable best efforts to cause the Company’s independent auditors to cooperate in connection with the Financing (including providing accountant’s comfort letters and
consents to use their audit reports from the Company’s independent auditors to the extent required in connection with such Financing); (v) obtaining customary payoff letters, releases of liens and other instruments of termination or
discharge reasonably requested by Parent in connection with the repayment of indebtedness of the Company and its Subsidiaries (other than Oncor Entities) as necessary to consummate the transactions contemplated by this Agreement or the Plan of
Reorganization; and (vi) otherwise cooperating with Parent to satisfy any express conditions precedent to the Financing within the control of the Company, provided in each case (A) such requested cooperation shall not unreasonably
interfere with the ongoing operations of the Company and its Subsidiaries, (B) neither the Company nor any of its Subsidiaries shall be required to pay any commitment or other similar fee or incur any other liability or obligation in connection
with the Financing prior to the Closing Date, (C) other than customary authorization letters, none of the Company, its Subsidiaries or their respective officers, directors, or employees shall be required to

  
 93 

 
execute or enter into or perform any agreement with respect to the Financing that is not contingent upon the Closing or that would be effective prior to the Closing Date nor prepare any pro forma
financial statements, (D) Persons who are on the board of directors or the board of managers (or similar governing body) of the Company and any of its Subsidiaries prior to the Closing Date in their capacity as such shall not be required to
pass resolutions or consents to approve or authorize the execution of the Financing, and (E) none of the Company or its Subsidiaries or their respective officers, directors, or employees shall be required to execute any solvency certificate in
connection with the Financing. Nothing contained in this Section 6.22(a) or otherwise shall require the Company or any of its Subsidiaries, prior to the Closing, to be an issuer or other obligor with respect to the Financing. 

(b) From and after the date hereof until the earlier of the Termination Date and the Closing Date, it is understood that Parent
may seek to market and consummate all or a portion of the Financing (the date of any such issuance, an “Early Financing Date”). In this regard, and for the avoidance of doubt, the Company and EFIH acknowledge that their cooperation
obligations set forth in Section 6.22(a) include the obligation to use their reasonable best efforts to cooperate with any such efforts, provided such cooperation obligations are limited to those set forth in Section 6.22(a).

 (c) Prior to the Closing Date, none of the Company, its Subsidiaries and its and their respective Representatives shall be
required to take any action that would subject such Person to actual or potential liability, to bear any cost or expense or to pay any commitment or other similar fee or make any other payment or incur any other liability or provide or agree to
provide any indemnity in connection with the Financing or their performance of their respective obligations under this Section 6.22 or any information utilized in connection therewith. Parent shall indemnify and hold harmless the
Company, its Subsidiaries and its and their respective Representatives from and against any and all Costs suffered or incurred by them in connection with the arrangement of the Financing and the performance of their respective obligations under this
Section 6.22 and any information utilized in connection therewith (other than arising from information provided by the Company or its Subsidiaries). Parent shall, promptly upon request of the Company if this Agreement is terminated in
accordance with its terms, reimburse the Company and its Subsidiaries for all reasonable and documented out-of-pocket costs and expenses incurred by the Company or its Subsidiaries (including those of its Representatives), in connection with the
cooperation required by this Section 6.22. The Company hereby consents to the use of the logos of the Company and its Subsidiaries in connection with the Financing; provided that such logos are used solely in a manner that is not
intended to or reasonably likely to harm or disparage the Company or any of its Subsidiaries or the reputation or goodwill of the Company or any of its Subsidiaries. 

(d) Parent and Merger Sub acknowledge and agree that the consummation by Parent of the transactions contemplated by this
Agreement or the Plan of Reorganization is not conditional upon the consummation of, or the receipt by Parent or Merger Sub or any of their Affiliates of the proceeds of, the Financing.

 ARTICLE VII 

Conditions 

Section 7.1 Conditions to All Parties’ Obligations. The obligations of each party to effect the Closing are subject to the
satisfaction or mutual waiver (as determined by the Company and, to the extent EFIH would be adversely affected by the Company’s actions, EFIH, on the one hand, and by Parent, on the other hand) of the following conditions at or prior to the
Closing: 
 (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”); (ii) an order, in form reasonably satisfactory to 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”); and (iii) an order confirming the Plan of Reorganization with respect to the TCEH Debtors, which in each case shall be in full force and effect 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. By the time of the Reorganized TCEH Spin-off the
Company and Reorganized TCEH shall have obtained an opinion of nationally recognized counsel or accounting firm selected by the Company in form and substance reasonably acceptable to the Company and Parent at a “should” or higher level, 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 and including the Fundamental Opinions listed in Exhibit I;
provided however, that if the Fundamental Rulings of Exhibit I in respect of section 368 continuity of interest, active trade or business, section 355 continuity of interest, and/or section 355(d) cannot be obtained because
insufficient information is available regarding the reorganization of the E-Side Debtors, but all other conditions to the Closing have been satisfied, then the opinion may assume such provisions are satisfied by the provision of a representation
that the Company and its Subsidiaries has no plan or intention to enter into any transaction that is inconsistent with the Intended Tax-Free Treatment. In rendering such opinion, the party providing the opinion shall be permitted to rely upon
reasonable representations, including a representation that the Company and its Subsidiaries have no plan or intention at the time of the Reorganized TCEH Spin-Off to take any action that is inconsistent with the Intended Tax-Free Treatment. 

  
 95 

 (d) TCEH Separation. The Reorganized TCEH Spin-Off shall have occurred in
all material respects in accordance with the Plan of Reorganization and the Private Letter Ruling. 
 (e) Closing
Debt. Assuming the Closing Date Transactions are consummated, neither the Company nor any of its Subsidiaries (other than the Oncor Entities) will have any indebtedness for borrowed money immediately following the Effective Time. 

(f) Private Letter Rulings. The Initial Private Letter Ruling shall remain in full force and effect and shall not have
been revoked or withdrawn, 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 I 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 I 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) 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 I,
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. 

(g) Tax Matters Agreement. Prior to, but contingent upon the Reorganized TCEH Spin-Off, the Tax Matters Agreement shall
have been entered into between the Company and Reorganized TCEH, in accordance with the terms hereof and the Plan of Reorganization, shall be in full force and effect and shall not have been amended, modified or supplemented without the consent of

amended, modified or supplemented without the consent of Parent.

 (i) NYSE Listing and SEC Registration. The shares of Parent Common Stock
issuable pursuant to this Agreement shall have been approved for listing on the NYSE, subject only to official notice of issuance, shall be freely saleable and not subject to any resale restrictions except to the extent such restrictions are due to
the status of the holder thereof, and either (i) the Form S-4, or other registration statement as applicable, shall have become and continue to be effective under the Securities Act and shall not be the subject of any stop order or proceedings
seeking a stop order, and Parent shall have received the state securities or “blue sky” authorizations necessary for the issuance of the shares of Parent Common Stock to be issued as the Stock Consideration or (ii) the SEC shall have
issued a favorable “no-action” letter to the effect that the exemption from the registration requirements of the Securities Act and from applicable state securities laws provided by Section 1145 of the Bankruptcy Code is applicable in

Entity or the Bankruptcy Court, necessary in connection with the consummation of the transactions contemplated by this Agreement shall have been obtained and shall remain in full force and effect, except such third party consents and approvals the

 101 

 Section 8.2 Termination by Either Parent or the Company/ EFIH. This Agreement may be
terminated at any time prior to the Closing by action of either (x) Parent, on the one hand, or (y) the Company and EFIH (acting together), on the other hand: 

(a) if the Closing (including the Closing Date Transactions) shall not have been consummated within two hundred forty
(240) days of the date of this Agreement (including as extended pursuant to this Section 8.2(a), the “Initial Termination Date”), provided, that, if as of such date any of the FERC Approval, the PUCT Approval
or the Private Letter Ruling (if applicable) shall not have been obtained (and such approval or Private Letter Ruling is still capable of being obtained within ninety (90) days), the Initial Termination Date shall be extended for ninety
(90) days for the purpose of continuing to pursue such approval or Private Letter Ruling, unless the Company and EFIH (acting together) and Parent agree otherwise in writing (the Initial Termination Date (as extended pursuant to this
Section 8.2(a), as applicable) being, the “Termination Date”), provided, further, that, the right to terminate this Agreement pursuant to this clause (a) shall not be available to any party whose
failure to fulfill any obligation under this Agreement has been the cause of (directly or indirectly), or resulted in, the failure of the Closing to occur on or before the Termination Date; or 

(b) if any order of any court or other Governmental Entity permanently restraining, enjoining, rendering illegal or otherwise
prohibiting, directly or indirectly, consummation of the Closing Date Transactions shall have become final and non-appealable; provided, however, that the termination right in this clause (b) shall not be available if the party seeking
to terminate this Agreement pursuant to this clause (b) shall not have used its reasonable best efforts (and caused each of its Subsidiaries and controlled Affiliates (other than the Oncor Entities) to use its reasonable best efforts) to
contest such order prior to its becoming permanent if such party (or Subsidiary or controlled Affiliate had the right to contest such order. 

Section 8.3 Termination by the Company and/or EFIH. This Agreement may be terminated at any time prior to the Closing: 

(a) by the Company and EFIH (acting together) if there has been a breach of any representation, warranty, covenant or agreement
made by Parent or Merger Sub in this Agreement, or any such representation or warranty shall have become untrue after the date of this Agreement, as if, in each such case, such representation or warranty were required by the Agreement to be true on
and as of each such date between the date hereof and the Closing Date, which breach or failure of a representation, warranty, covenant or agreement to be true or to be performed (i) would result in a failure of a condition set forth in any
provision of Section 7.1 or Section 7.3 (which for the purpose of such clauses it shall be assumed such breach is continuing as of the Closing) and (ii) cannot be, or has not been, cured within thirty (30) Business
Days after Parent’s receipt of written notice thereof from the Company or EFIH; provided, however, that the termination right in this clause (a) shall not apply if either the Company or EFIH is then in breach of this
Agreement in a manner that would result or has resulted in any of the conditions set forth in Section 7.1 or Section 7.2 not being satisfied; 

  
 102 

 (b) by the Company and EFIH (acting together) if Parent and Merger Sub have
failed to consummate the Closing no later than the date required by Section 1.4; provided, however, that the termination right in this clause (b) shall not apply if either the Company or EFIH is then in breach of this
Agreement in a manner that would result or has resulted in any of the conditions set forth in Section 7.1 or Section 7.2 not being satisfied; 

(c) by the Company and EFIH (acting together) if the Bankruptcy Court enters an order approving a plan of reorganization not
proposed or supported by the Company or EFIH (and which the Company and EFIH, to the extent requested by Parent, used commercially reasonable efforts to challenge before the Bankruptcy Court) that is inconsistent with this Agreement or the Plan of
Reorganization; 
 (d) by the Company and EFIH (acting together) if the Chapter 11 Cases are dismissed or converted to
a case under Chapter 7 of the Bankruptcy Code and neither such dismissal or conversion contemplates the Closing Date Transactions; provided, that such dismissal or conversion was not proposed or supported by the Company or EFIH (and which the
Company and EFIH, to the extent requested by Parent, used commercially reasonable efforts to challenge before the Bankruptcy Court); 

(e) until the entry of the EFH Confirmation Order, by the Company if concurrently with such termination, the Company Board
determines in its sole discretion after consultation with its independent financial advisors and outside legal counsel, and based on the advice of such counsel, that the failure to terminate this Agreement is inconsistent with its fiduciary duties,
provided that a material breach of the Company’s or EFIH’s obligations under Section 6.2 has not provided the basis for such determination; 

(f) until the entry of the EFH Confirmation Order, by EFIH if concurrently with such termination, the board of managers of EFIH
determines in its sole discretion after consultation with its independent financial advisors and outside legal counsel, and based on the advice of such counsel, that the failure to terminate this Agreement is inconsistent with its fiduciary duties,
provided that a material breach of the Company’s or EFIH’s obligations under Section 6.2 has not provided the basis for such determination; or 

(g) by the Company and EFIH (acting together) upon any termination of the Plan Support Agreement in accordance with its terms
as to the Company, EFIH, Parent or Merger Sub. 
 Section 8.4 Termination by Parent. This Agreement may be terminated at any
time prior to the Closing by Parent:

on and as of each such date between the date hereof and the Closing Date, which 

  
 103 

 
breach or failure of a representation, warranty, covenant or agreement to be true or to be performed (i) would result in a failure of a condition set forth in any provision of
Section 7.1 or Section 7.2 (which for the purpose of such clauses it shall be assumed such breach is continuing as of the Closing), and (ii) cannot be or has not been cured within thirty (30) Business Days after the
Company’s or EFIH’s receipt of written notice thereof from Parent; provided, however, that the termination right in this clause (a) shall not apply if either Parent or Merger Sub is then in breach of this Agreement or
the Oncor Letter Agreement in a manner that would result or has resulted in any of the conditions set forth in Section 7.1 or Section 7.3 not being satisfied; 

(b) if there has been a breach of any representation, warranty, covenant or agreement made by Oncor or Oncor Holdings under the
Oncor Letter Agreement, or any such representation or warranty shall have become untrue after the date of this Agreement, as if, in each such case, such representation or warranty were required by the Agreement to be true on and as of each such date
between the date hereof and the Closing Date, which breach or failure of a representation, warranty, covenant or agreement to be true or to be performed (i) would result in a failure of a condition set forth in any provision of
Section 7.1 or Section 7.2 (which for the purpose of such clauses it shall be assumed such breach is continuing as of the Closing) and (ii) cannot be or has not been cured within thirty (30) Business Days after the
Company’s, EFIH’s, Oncor’s and Oncor Holdings’ receipt of written notice thereof from Parent; provided, however, that the termination right in this clause (b) shall not apply if either Parent or Merger Sub is
then in breach of this Agreement or the Oncor Letter Agreement in a manner that would result or has resulted in any of the conditions set forth in Section 7.1 or Section 7.3 not being satisfied;

provided, however, that the termination right in this clause (c) shall not apply if either Parent nor Merger Sub is then in breach of this Agreement or the Oncor Letter Agreement in a manner that would result or has resulted in
the failure to consummate the Closing; 
 (d) if the Company or EFIH files or expressly supports in the Bankruptcy Court a
plan of reorganization that is inconsistent in any substantive legal or economic respect with this Agreement and the Plan of Reorganization (solely as it the Plan of Reorganization relates to the E-Side Debtors) and such inconsistency cannot be or
has not been cured within thirty (30) Business Days after the Company’s or EFIH’s receipt of written notice thereof from Parent (which notice must occur within five (5) Business Days of the filing of such Plan); 

(e) if the Bankruptcy Court enters an order, or if the Company or EFIH files a motion seeking entry of an order, approving any
sale or other disposition (other than a sale or other disposition permitted by this Agreement) of (i) any material portion of the assets of the Company or its Subsidiaries or (ii) any equity interests in EFIH or any of its Subsidiaries

Company LLC, (ii) EECI, Inc., (iii) EEC Holdings, Inc., and (iv) LSGT SACROC, Inc., is dismissed or converted to a case under Chapter 7 of the Bankruptcy Code and neither such dismissal or conversion contemplates the Closing Date
Transactions and the other transactions contemplated by this Agreement; 
 (h) if the Bankruptcy Court orders the substantive
consolidation of (i) the chapter 11 estates of the Company and/or EFIH and/or any of their respective Subsidiaries, on one hand, with (ii) the chapter 11 estates of EFCH and/or any of its Subsidiaries, on the other hand;

 (k) if Parent, Merger Sub, Oncor and Oncor Holdings fail to enter into the Oncor Letter
Agreement in substantially the form attached hereto as Exhibit K within seven (7) days following the date hereof; provided however if Parent has not terminated this Agreement pursuant to this Section 8.4(k) thirteen
(13) days after such seven (7) day period elapses, this Section 8.4(k) shall be of no further force and effect and Parent shall have no such right to terminate this Agreement.

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
transactions contemplated by this Agreement (which liability the parties hereto acknowledge and agree shall not be limited to reimbursement of expenses or out-of-pocket costs). 

  
 105 

 (b) If this Agreement is terminated pursuant to this Article VIII and any
alternative transaction is consummated (including 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 neither Parent nor any of
its Affiliates will obtain direct or indirect ownership of 100% of Oncor Holdings and Oncor Holdings’ approximately 80% equity interest in Oncor, then, subject to the approval of the Bankruptcy Court, 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; provided, however,
that the Termination Fee (as defined below) will not be payable if this Agreement is terminated (i) pursuant to Section 8.1, (ii) by Parent pursuant to Section 8.2(a) and the receipt of the PUCT Approval (without
the imposition of a Burdensome Condition) is the only condition set forth in Article VII not satisfied or waived in accordance with this Agreement (other than those conditions that by their nature or pursuant to the terms of this Agreement are to be
satisfied at the Closing) or 8.2(b), or 8.4(g) (unless the Chapter 11 Cases are dismissed or converted to Chapter 7 of the Bankruptcy Code with respect to the Company or EFIH in which case the Termination Fee is payable) or
Section 8.4(i) if the Plan Support Agreement is terminated pursuant to a breach thereof by Parent or Merger Sub, or (iii) by the Company pursuant to Section 8.3(a), 8.3(b), or 8.3(g) to the extent that the
Plan Support Agreement is terminated pursuant to a breach thereof by Parent or Merger Sub. 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. Subject to the Bankruptcy Court’s approval of
the Termination Fee, 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. The Termination Fee, to the extent approved by the Bankruptcy

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 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.

(a) THIS AGREEMENT SHALL BE CONSTRUED, PERFORMED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE, WITHOUT
GIVING EFFECT TO ITS PRINCIPLES OR RULES OF CONFLICT OF LAWS TO THE EXTENT SUCH PRINCIPLES OR RULES WOULD REQUIRE OR PERMIT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION. Each of the parties hereto (i) submits to the exclusive
jurisdiction of the Bankruptcy Court (or, if the Bankruptcy Court declines to accept jurisdiction over a particular matter, then the Chancery Court of the State of Delaware, and if the Chancery Court of the State of Delaware declines jurisdiction,

(iii) agrees not to bring any action or proceeding arising out of or relating to this Agreement in any other court. Each of the parties hereto agrees that a final judgment (subject to any appeals therefrom) in any such action or proceeding
shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. Each of the parties hereto hereby irrevocably and unconditionally waives, to the fullest extent it may legally and
effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or the transactions contemplated by this Agreement in any Delaware or federal
court in accordance with the provisions of this Section 9.5(a). Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or
proceeding in any such court. Each of the parties hereto hereby irrevocably and unconditionally consents to service of process in the manner provided for notices in Section 9.6. Nothing in this Agreement will affect the right of any
party to this Agreement to serve process in any other manner permitted by Law. 

  
 107 

 (b) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER
THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY
ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE,
THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (ii) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH PARTY MAKES THIS WAIVER VOLUNTARILY, AND
(iv) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS Section 9.5.

Section 9.7 Entire Agreement. This Agreement (including any exhibits or schedules hereto including as actually executed), the
Company Disclosure Letter, the Parent Disclosure Letter, the Oncor Letter Agreement, the Plan Support Agreement, the Confidentiality Agreement, dated June 1, 2016, by and among Parent, the Company and EFIH and, pursuant to a Joinder dated
June 1, 2016, Oncor (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, THE PLAN SUPPORT 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 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 9.8 No Third Party Beneficiaries. Except as provided in
Section 6.8, and Section 6.12, 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. 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. 

  
 110 

 Section 9.9 Obligations 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 9.10 Remedies. 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. 

Section 9.11 Transfer Taxes. To the extent payable under applicable Law (notwithstanding section 1146 of the Bankruptcy Code), all
transfer, documentary, sales, use, stamp, registration and other similar such Taxes and fees (including penalties and interest) incurred in connection with the Merger shall be paid by the Surviving Company when due. 

Section 9.12 Definitions. Each term set forth in the Table of Defined Terms is defined on the page of this Agreement set forth
opposite such term. 
 Section 9.13 Severability. 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. 

Section 9.14 Interpretation; Construction. 

(a) The table of contents and headings herein are for convenience of reference only, do not constitute part of this Agreement
and shall not be deemed to limit or otherwise affect any of the provisions hereof. Where a reference in this Agreement is made to a section or exhibit, such reference shall be to a section of or exhibit to this Agreement unless otherwise indicated.
Such exhibits are an integral part of this Agreement as if fully set forth herein. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words

  
 111 

 
“without limitation.” The words “hereof,” “hereto,” “hereby,” “herein” and “hereunder” and words of similar import when used in this
Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The term “made available” and words of similar import means that the relevant documents, instruments or materials were either
(i) posted and made available to the other party or its designated Representatives on the Intralinks due diligence data site maintained by the Company for purposes of the transaction(s) contemplated by this Agreement, (ii) sent to the
other party or its representatives directly, or (iii) publicly available by virtue of the relevant party’s filing of a publicly available final registration statement, prospectus, report, form, schedule or definitive proxy statement filed
with the SEC pursuant to the Securities Act or the Exchange Act, in each case, at least five (5) Business Days prior to the date hereof or such prior date with respect to which such documents, instruments or materials were represented by a
party to have been made available to the other party. The words “shall” and “will” have the same meaning. 

(b) The parties hereto have participated jointly in negotiating and drafting this Agreement. In the event that an ambiguity or
a question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any
provision of this Agreement. 
 (c) Subject to the first paragraphs of Sections 5.1 and 5.2, respectively, each
of the Company, EFIH, Parent and Merger Sub has, or may have, set forth information in its respective Disclosure Letter in a section thereof that corresponds to the section of this Agreement to which it relates. The fact that any item of information
is disclosed in a Disclosure Letter to this Agreement shall not be construed to mean that such information is required to be disclosed by this Agreement. 

Section 9.15 Assignment. This Agreement shall not be assignable by operation of law or otherwise without the prior written consent
of the non-assigning parties hereto (such consent not to be unreasonably withheld, conditioned or delayed). Any purported assignment in violation of this Agreement is void.

the outstanding claims against, and interests in, the Debtors pursuant to the Bankruptcy Code. Capitalized terms used herein and not otherwise defined shall have the meanings ascribed to them in Article I.A of the Plan. Holders of Claims and

 ARTICLE II. 

ADMINISTRATIVE CLAIMS, DIP CLAIMS, AND PRIORITY TAX CLAIMS 

In accordance with section 1123(a)(1) of the Bankruptcy Code, Administrative Claims, DIP Claims, and Priority Tax Claims have not been
classified and, thus, are excluded from the Classes of Claims and Interests. 
  

	A.	Administrative Claims. 

 1. General Administrative Claims. 

Except as specified in this Article II, unless the Holder of an Allowed General Administrative Claim and the Debtors or the Reorganized
Debtors, as applicable, agree to less favorable treatment, each Holder of an Allowed General Administrative Claim will receive, in full satisfaction of its General Administrative Claim, Cash equal to the amount of such Allowed General Administrative
Claim either: (a) on the Effective Date; (b) if the General Administrative Claim is not Allowed as of the Effective Date, 60 days after the date on which an order allowing such General Administrative Claim becomes a Final Order, or as soon
thereafter as reasonably practicable; or (c) if the Allowed General Administrative Claim is based on a liability incurred by the Debtors in the ordinary course of their business after the Petition Date, pursuant to the terms and conditions of
the particular transaction or agreement giving rise to such Allowed General Administrative Claim, without any further action by the Holders of such Allowed General Administrative Claim, and without any further notice to or action, order, or approval
of the Bankruptcy Court. 
 Requests for payment of General Administrative Claims must be Filed and served on the Debtors or the Reorganized
Debtors, as applicable, no later than the Administrative Claims Bar Date applicable to the Debtor against whom the General Administrative Claim is asserted pursuant to the procedures specified in the Confirmation Order and the notice of the
Effective Date. Holders of General Administrative Claims that are required to File and serve a request for payment of such General Administrative Claims by the Administrative Claims Bar Date that do not File and serve such a request by the
Administrative Claims Bar Date shall be forever barred, estopped, and enjoined from asserting such General Administrative Claims against the Debtors, the Reorganized Debtors, or their respective property and such General Administrative Claims shall
be deemed forever discharged and released as of the Effective Date. Any requests for payment of General Administrative Claims that are not properly Filed and served by the Administrative Claims Bar Date shall not appear on the Claims Register and
shall be disallowed automatically without the need for further action by the Debtors or the Reorganized Debtors or further order of the Bankruptcy Court. To the extent this Article II.A.1 conflicts with Article XII.C of the Plan with respect to fees
and expenses payable under section 1930(a) of the Judicial Code, including fees and expenses payable to the U.S. Trustee, Article XII.C of the Plan shall govern. 

  
 44 

	2.	Professional Compensation. 

  

	 	(a)	Final Fee Applications. 

 All final requests for payment of Professional Fee Claims, including
the Professional Fee Claims incurred during the period from the Petition Date through the Effective Date, must be Filed and served on the Debtors or Reorganized Debtors, as applicable, no later than the Administrative Claims Bar Date. All such final
requests will be subject to approval by the Bankruptcy Court after notice and a hearing in accordance with the procedures established by the Bankruptcy Code and prior orders of the Bankruptcy Court in the Chapter 11 Cases, including the Interim
Compensation Order, and once approved by the Bankruptcy Court, promptly paid from the Professional Fee Escrow Account up to its full Allowed amount. 
  

	 	(b)	Professional Fee Escrow Accounts. 

 On the TCEH Effective Date, the Reorganized TCEH Debtors
shall establish and fund the TCEH Professional Fee Escrow Account with Cash equal to the TCEH Professional Fee Reserve Amount. On the EFH Effective Date, the EFH Debtors and the EFIH Debtors shall establish and fund the EFH Professional Fee Escrow
Account and the EFIH Professional Fee Escrow Account, respectively, with Cash equal to the EFH Professional Fee Reserve Amount and the EFIH Professional Fee Reserve Amount, respectively. 

Upon the establishment of the applicable Professional Fee Escrow Account, the Reorganized TCEH Debtors, the EFIH Debtors, and the EFH Debtors
shall select a Professional Fee Escrow Agent for the applicable Professional Fee Escrow Account to administer payments to and from such Professional Fee Escrow Account in accordance with the Plan and shall enter into escrow agreements providing for
administration of such payments in accordance with the Plan. 
 The Professional Fee Escrow Accounts shall be maintained in trust solely for
the Professionals. Such funds shall not be considered property of the Estates of the Debtors or the Reorganized Debtors. The amount of Professional Fee Claims owing to the Professionals shall be paid in Cash to such Professionals from the applicable
Professional Fee Escrow Account when such Professional Fee Claims are Allowed by a Final Order. 
  

	 	(c)	Professional Fee Reserve Amount. 

 Professionals shall estimate their unpaid Professional
Fee Claims and other unpaid fees and expenses incurred in rendering services to the Debtors before and as of the Effective Date and shall deliver such estimate to the Debtors no later than five days before the Effective Date; provided,
however, that such estimate shall not be deemed to limit the amount of the fees and expenses that are the subject of the Professional’s final request for payment of Filed Professional Fee Claims. If a Professional does not provide an
estimate, the Debtors may estimate the unpaid and unbilled fees and expenses of such Professional.  
 The total amount estimated
pursuant to this section shall: (a) as estimated to be allocated to the TCEH Debtors or the Reorganized TCEH Debtors in accordance with Article II.A.2(d) of the Plan, comprise the TCEH Professional Fee Reserve Amount; (b) as estimated to
be allocated to the EFH Debtors or the Reorganized EFH Debtors in accordance with Article II.A.2(d) of the Plan, comprise the EFH Professional Fee Reserve Amount; and (c) as estimated to be allocated to the EFIH Debtors or the Reorganized EFH
Debtors in accordance with Article II.A.2(d) of the Plan, comprise the EFIH Professional Fee Reserve Amount. 
  

	 	(d)	Allocation of Professional Fee Claims. 

 Allowed Direct Professional Fee Claims shall be
allocated to, and paid from, the applicable Professional Fee Escrow Account. Allowed Collective Professional Fee Claims shall be allocated to, and paid from, the applicable Professional Fee Escrow Account in the same proportion that the amount of
Allowed Direct Professional Fee Claims incurred by such Professional for such Debtor bears to the total amount of Allowed Direct Professional Fee Claims incurred by such Professional for all of the Debtors. 

  
 45 

	 	(e)	Post-Effective Date Fees and Expenses. 

 When all Allowed amounts owing to Professionals have
been paid in full from the applicable Professional Fee Escrow Account, any remaining amount in such Professional Fee Escrow Account shall be disbursed as follows without any further action or order of the Bankruptcy Court: (a) from the TCEH
Professional Fee Account, to the Reorganized TCEH Debtors; (b) from the EFH Professional Fee Account, to the EFH/EFIH Distribution Account, on account of the EFH Creditor Recovery Pool; and (c) from the EFIH Professional Fee Account, to
the EFH/EFIH Distribution Account, on account of the EFIH Unsecured Creditor Recovery Pool. 
 If the amount in any Professional Fee Escrow
Account is insufficient to fund payment in full of all Allowed amounts owing to Professionals, the deficiency shall be promptly funded to the applicable Professional Fee Escrow Account as follows without any further action or order of the Bankruptcy
Court: (a) as to the TCEH Debtors or the Reorganized TCEH Debtors, by the Reorganized TCEH Debtors; (b) as to the EFH Debtors, from the EFH/EFIH Distribution Account, on account of the EFH Creditor Recovery Pool; and (c) as to the
EFIH Debtors, from the EFH/EFIH Distribution Account, on account of the EFIH Unsecured Creditor Recovery Pool. 
 Upon the Effective
Dates, any requirement that Professionals comply with sections 327 through 331, 363, and 1103 of the Bankruptcy Code in seeking retention or compensation for services rendered after such date shall terminate, and the Debtors or Reorganized Debtors
may employ and pay any Professional in the ordinary course of business without any further notice to or action, order, or approval of the Bankruptcy Court; provided, however, that, for the avoidance of doubt, the Reorganized EFH Debtors and
the Reorganized EFIH Debtors shall not be liable or otherwise responsible for the payment of any Professional Fee Claims. 
  

	B.	DIP Claims. 

  

	 	1.	TCEH DIP Claims. 

 The TCEH DIP Claims shall be Allowed in the full amount due and owing under

DIP L/C is no longer in effect), (ii) such TCEH DIP L/C shall have been collateralized in Cash in an amount equal to 101% of the undrawn face amount of such TCEH DIP L/C, pursuant to documentation in form and substance satisfactory to the

of receiving distributions pursuant to the Plan only to the extent that such Claim or Interest is an Allowed Claim or Allowed Interest in that Class and has not been paid, released, or otherwise satisfied before the applicable Effective Date. The
Debtors reserve the right to assert that the treatment provided to Holders of Claims and Interests pursuant to Article III.B of the Plan renders such Holders Unimpaired.

 The Plan constitutes a separate chapter 11 plan of

(a) the Spin-Off Conditions are satisfied on or before the Spin-Off Conditions Termination Date and (b) the Spin-Off Conditions remain satisfied as of the TCEH Effective Date, then the TCEH Debtors will effectuate the Spin-Off on the TCEH
Effective Date. In all other circumstances, the TCEH Debtors will effectuate the Taxable Separation on the TCEH Effective Date. For the avoidance of doubt, if the Spin-Off Conditions are not satisfied on or before the Spin-Off Conditions Termination

Participant Agreement, and the Separation Agreement must be in full force and effect and, in each case, be in form and substance acceptable to the Plan Sponsor.

accordance with the Plan that are to be made after the TCEH Effective Date; 

  

	 	C.	pursuant to the Separation Agreement, TCEH and the EFH Debtors will make the Contribution to Reorganized TCEH, in exchange for which TCEH shall receive 100% of the (i) Reorganized TCEH membership interests and
(ii) the net Cash proceeds of the New Reorganized TCEH Debt (or, at the TCEH Supporting First Lien Creditors’ election, with the consent of the Debtors, all or a portion of such New Reorganized TCEH Debt); 

 

	 	D.	immediately following the Contribution, TCEH and Reorganized TCEH shall effectuate the Spin-Off Preferred Stock Sale, including the distribution of the proceeds thereof to TCEH; 

 

	 	E.	immediately following the Spin-Off Preferred Stock Sale, Reorganized TCEH shall undertake the Reorganized TCEH Conversion; and 

  

	 	F.	immediately following the Reorganized TCEH Conversion, TCEH will make the Distribution, and all Claims against the TCEH Debtors (other than liabilities assumed by Reorganized TCEH pursuant to the Plan) will be cancelled
in connection therewith. 

  

	 	(b)	Taxable Separation. If applicable, the TCEH Debtors will undertake the Taxable Separation, as set forth in the [Taxable Separation Memorandum].

 6. Tax Matters Agreement.

equal to the difference in such amounts. Upon conclusion of the Post-Closing Audit, the EFH Plan Administrator Board shall direct that an amount of Cash shall be transferred from the EFH/EFIH Distribution Account to (i) the EFH Creditor
Recovery Pool equal to the amount, if any, by which the Adjusted Company Cash Amount exceeds the NextEra Class A Common Stock Investment or (ii) NextEra equal to the amount, if any, by which the NextEra Common Stock Investment exceeds the

Except (i) as otherwise provided in the Plan or the Plan Supplement and (ii) with respect to the EFH

 Q. Preservation of Causes of Action. 

In accordance with section 1123(b) of the Bankruptcy Code, but subject to Article VIII of the Plan, the Reorganized Debtors shall retain and
may enforce all rights to commence and pursue any and all Causes of Action belonging to their Estates, whether arising before or after the Petition Date, including any actions specifically enumerated in the Plan Supplement, and the Reorganized
Debtors’ rights to commence, prosecute, or settle such Causes of Action shall be preserved notwithstanding the occurrence of the applicable Effective Date, other than: (i) the Causes of Action released by the Debtors pursuant to the
releases and exculpations contained in the Plan, including in Article VIII, which shall be deemed released and waived by the Debtors and Reorganized Debtors as of the Effective Date; (ii) all Causes of Action that arise under sections 544, 547,
548, and 549 of the Bankruptcy Code and state fraudulent conveyance law; and (iii) the Causes of Action released by the Debtors pursuant to the Settlement Agreement. 

The Reorganized Debtors may pursue such Causes of Action, as appropriate, in accordance with the best interests of the Reorganized
Debtors. No Entity may rely on the absence of a specific reference in the Plan, the Plan Supplement, or the Disclosure Statement to any Cause of Action against it as any indication that the Debtors or the Reorganized Debtors, as applicable, will
not pursue any and all available Causes of Action against it. Unless any Causes of Action against an Entity are expressly waived, relinquished, exculpated, released, compromised, or settled herein or in a Bankruptcy Court order, the Reorganized
Debtors expressly reserve all Causes of Action, for later adjudication, and, therefore, no preclusion doctrine, including the doctrines of res judicata, collateral estoppel, issue preclusion, claim preclusion, estoppel (judicial, equitable, or
otherwise), or laches, shall apply to such Causes of Action upon, after, or as a consequence of Confirmation or Consummation. 
 The
Reorganized Debtors reserve and shall retain the Causes of Action notwithstanding the rejection of any Executory Contract or Unexpired Lease during the Chapter 11 Cases or pursuant to the Plan. In accordance with section 1123(b)(3) of the Bankruptcy
Code, any Causes of Action that a Debtor may hold against any Entity shall vest in the Reorganized Debtors. The Reorganized Debtors shall have the exclusive right, authority, and discretion to determine and to initiate, file, prosecute, enforce,
abandon, settle, compromise, release, withdraw, or litigate to judgment any such Causes of Action and to decline to do any of the foregoing without the consent or approval of any third party or further notice to or action, order, or approval of the
Bankruptcy Court. 
 R. Payment of Certain Fees. 

1. Payment of Fees of Certain Creditors of the EFIH Debtors. 

Without any further notice to or action, order, or approval of the Bankruptcy Court, the EFH Plan Administrator Board shall pay from the

 The EFH Plan Administrator Board shall pay from the EFH/EFIH Distribution Account the reasonable and documented fees
and expenses allowed under the EFIH Unsecured Note Indentures, and the EFH Notes Indentures; provided, however, that such fees and expenses shall be subject to approval by the Fee Committee, with respect to the reasonableness of such
documented fees and expenses in their reasonable discretion, and the Bankruptcy Court; provided further, however, that such fees and expenses shall be paid on the EFH Effective Date or as soon as reasonably practicable thereafter
following Fee Committee and Bankruptcy Court approval thereof; provided, further, that, for the avoidance of doubt, such fees and expenses shall not be included in the amount of any Allowed Claims under the EFIH Unsecured Notes Indentures or
the EFH Notes Indentures. 
 Without any further notice to or action, order, or approval of the Bankruptcy Court, the EFH Plan Administrator
Board shall pay from the EFH/EFIH Distribution Account the reasonable and documented fees and expenses of the Auditor in conducting the Post-Closing Report and as otherwise provided in the Merger Agreement. 

  
 81 

 All amounts distributed and paid pursuant to this Article IV.R.1. shall not be subject to
disgorgement, setoff, recoupment, reduction, or reallocation of any kind. 
 2. Payment of Fees of Certain Creditors of the TCEH Debtors.

 Without any further notice to or action, order, or approval of the Bankruptcy Court, the Reorganized TCEH Debtors shall pay on the TCEH
Effective Date any reasonable and documented unpaid fees and expenses incurred on or before the TCEH Effective Date by professionals (a) payable under (1) the TCEH DIP Facility (which fees and expenses shall be paid by Reorganized TCEH),
and (2) the Cash Collateral Order (which fees and expenses shall be paid by TCEH or Reorganized TCEH), including any applicable transaction, success, or similar fees for which the applicable Debtors have agreed to be obligated, and
(b) retained by any individual member of the TCEH First Lien Ad Hoc Committee that is a TCEH Supporting First Lien Creditor. Reorganized TCEH shall indemnify (a) the TCEH First Lien Agent for any reasonable and documented fees and expenses
(including the reasonable and documented fees and expenses of its counsel and agents) incurred after the TCEH Effective Date solely in connection with the implementation of the Plan, including but not limited to, making distributions pursuant to and
in accordance with the Plan, and any disputes arising in connection therewith; and (b) any member or members of the TCEH First Lien Ad Hoc Committee for any reasonable and documented fees and expenses (including the reasonable and documented
fees and expenses of its counsel and agents) incurred after the TCEH Effective Date solely in connection with the TCEH First Lien Creditor Deposit L/C Collateral Allocation Dispute. 

All amounts distributed and paid pursuant to this Article IV.R.2 shall not be subject to disgorgement, setoff, recoupment, reduction, or
reallocation of any kind. 
 S. Treatment of Certain Claims of the PBGC and Pension Plan. 

Nothing in the Chapter 11 Cases, the Disclosure Statement, the Plan, the Confirmation Order, or any other document filed in the Chapter 11
Cases shall be construed to discharge, release, limit, or relieve any individual from any claim by the PBGC or the Pension Plans for breach of any fiduciary duty under ERISA, including prohibited transactions, with respect to the Pension Plans,
subject to any and all applicable rights and defenses of such parties, which are expressly preserved. The PBGC and the Pension Plans shall not be enjoined or precluded from enforcing such fiduciary duty or related liability by any of the provisions
of the Disclosure Statement, Plan, Confirmation Order, Bankruptcy Code, or other document filed in the Chapter 11 Cases. For the avoidance of doubt, the Reorganized Debtors shall not be released from any liability or obligation under ERISA, the
Internal Revenue Code, and any other applicable law relating to or arising from the Pension Plans.

the Distribution. Only Holders of Allowed TCEH First Lien Secured Claims that timely return a TRA Information Form shall be entitled to receive beneficial interests in the Spin-Off TRA Rights (if any). Holders of Allowed TCEH First Lien Secured

 ARTICLE
V. 
 TREATMENT OF EXECUTORY CONTRACTS AND UNEXPIRED LEASES 

A. Assumption and Rejection of Executory Contracts and Unexpired Leases. 

1. Rejection of EFH Debtor and EFIH Debtor Executory Contracts and Unexpired Leases 

On the EFH Effective Date, except as otherwise provided herein or in the Confirmation Order, all Executory Contracts or Unexpired Leases
of the EFH Debtors or the EFIH Debtors, not previously assumed or rejected pursuant to an order of the Bankruptcy Court, including the TCEH Confirmation Order or the EFH Confirmation Order, will be deemed to be Rejected Executory Contracts or
Unexpired Leases, in accordance with the provisions and requirements of sections 365 and 1123 of the Bankruptcy Code, other than those Executory Contracts or Unexpired Leases that are: (1) identified on the EFH/EFIH Assumed Executory Contract
and Unexpired Lease List; (2) the subject of a motion to assume Executory Contracts or Unexpired Leases that is pending on the Confirmation Date; or (3) subject to a motion to reject an Executory Contract or Unexpired Lease pursuant to
which the requested effective date of such rejection is after the Effective Date; provided that each of (1), (2) and (3) must be in form and substance acceptable to the Plan Sponsor. Entry of the EFH Confirmation Order by the
Bankruptcy Court shall constitute approval of such rejections and the assignments and/or assumptions of the Executory Contracts or Unexpired Leases listed on the EFH/EFIH Assumed Executory Contract and Unexpired Lease List pursuant to sections
365(a) and 1123 of the Bankruptcy Code. Any motions to assume Executory Contracts or Unexpired Leases of the EFH Debtors or EFIH Debtors pending on the EFH Effective Date shall be subject to approval by the Bankruptcy Court on or after the Effective
Date by a Final Order. Each Executory Contract and Unexpired Lease assumed pursuant to this Article V.A.1 or by any order of the Bankruptcy Court, which has not been assigned to a third party before the Confirmation Date, shall revest in and be
fully enforceable by Reorganized EFH or Reorganize EFIH, as applicable, or their successors in accordance with its terms, except as such terms are modified by the Plan or any order of the Bankruptcy Court authorizing and providing for its assumption
under applicable federal law. The Plan Sponsor, Reorganized EFH, and Reorganized EFIH, as applicable, reserve the right to alter, amend, modify, or supplement the EFH/EFIH Assumed Executory Contract and Unexpired Lease List and the schedules of
Executory Contracts and Unexpired Leases with respect to EFH, Reorganized EFH, EFIH, and Reorganized EFIH at any time through and including 45 days after the Effective Date, without incurrence of any penalty or changing the priority or security of
any Claim as a result of such treatment change. For the avoidance of doubt, and notwithstanding anything herein to the contrary, the Tax Matters Agreement, the Transition Services Agreement, and the Separation Agreement, to the extent in the form
attached to the Merger Agreement or as amended or modified in accordance with their respective terms and with the consent of the Plan Sponsor, shall be EFH/EFIH Assumed Executory Contracts or Unexpired Leases. 

2. Assumption of TCEH Debtor Executory Contracts and Unexpired Leases. 

On the TCEH Effective Date, except as otherwise provided herein, all TCEH Executory Contracts or Unexpired Leases of the TCEH Debtors,
not previously assumed or rejected pursuant to an order of the Bankruptcy Court, will be deemed to be TCEH Assumed Executory Contracts or Unexpired Leases, in accordance with the provisions and requirements of sections 365 and 1123 of the
Bankruptcy Code, other than those Executory Contracts or Unexpired Leases that: (1) previously were assumed or rejected by the Debtors; (2) are identified on the TCEH Rejected Executory Contract and Unexpired Lease List; (3) are the
subject of a motion to reject TCEH Executory Contracts or Unexpired Leases that is pending on the Confirmation Date; or (4) are subject to a motion to reject a TCEH Executory Contract or Unexpired Lease pursuant to which the requested effective
date of such rejection is after the Effective Date; provided that each of (2), (3) and (4) must be in form and substance reasonably acceptable  

  
 83 

 
to the TCEH Supporting First Lien Creditors. Entry of the Confirmation Order by the Bankruptcy Court shall constitute approval of such assignments and/or assumptions and the rejection of the
Executory Contracts or Unexpired Leases listed on the Rejected Executory Contract and Unexpired Lease List pursuant to sections 365(a) and 1123 of the Bankruptcy Code. Any motions to assume Executory Contracts or Unexpired Leases pending on the
Effective Date shall be subject to approval by the Bankruptcy Court on or after the Effective Date by a Final Order. Each Executory Contract and Unexpired Lease assumed pursuant to this Article V.A.2 or by any order of the Bankruptcy Court, which
has not been assigned to a third party before the Confirmation Date, shall revest in and be fully enforceable by the Reorganized TCEH Debtors in accordance with its terms, except as such terms are modified by the Plan or any order of the Bankruptcy
Court authorizing and providing for its assumption under applicable federal law. Notwithstanding anything this Article V.A.2 to the contrary, the Employment Agreements, the New Employee Agreements/Arrangements, and the Executive Severance Policy
shall be deemed to be entered into or assumed and/or assigned (as applicable) to Reorganized TCEH on the TCEH Effective Date, and Reorganized TCEH shall be responsible for any cure costs arising from or related to the assumption of such Employment
Agreement or Executive Severance Policy; provided that, for the avoidance of doubt, in the event any party to an Employment Agreement and the Reorganized EFH Debtors or Reorganized EFIH Debtors mutually agree that such party’s Employment
Agreement shall be assumed by Reorganized EFH or Reorganized EFIH and not assigned to Reorganized TCEH, the consent of the Plan Sponsor shall be required with respect to such assumption and the Reorganized EFH Debtors and Reorganized EFIH Debtors,
as applicable, shall be responsible for any cure costs arising from or related to the assumption of such Employment Agreements. Additionally, notwithstanding anything to the contrary in the Plan, the Plan Supplement, the Executive Severance Policy,
or any Employment Agreement, the occurrence of the TCEH Effective Date shall be deemed to constitute a “change in control” under the Executive Severance Policy and each Employment Agreement. On the TCEH Effective Date, Reorganized TCEH
shall execute a written agreement (in a form reasonably acceptable to the TCEH Supporting First Lien Creditors) with each employee who is party to an Employment Agreement acknowledging that the transactions consummated upon the occurrence of the
TCEH Effective Date shall constitute a “change in control” under such employee’s Employment Agreement. The Debtors or the Reorganized Debtors, as applicable, with the reasonable consent of the Plan Sponsor and the TCEH Supporting
First Lien Creditors, reserve the right to alter, amend, modify, or supplement the schedules of Executory Contracts and Unexpired Leases with respect to such Debtors and Reorganized Debtors at any time through and including 45 days after the
Effective Date, without incurrence of any penalty or changing the priority or security of any Claim as a result of such treatment change. For the avoidance of doubt, and notwithstanding anything herein to the contrary, the Tax Matters Agreement,
Transition Services Agreement, Separation Agreement, and Amended and Restated Split Participant Agreement, to the extent in the form attached to the Merger Agreement or as amended or modified in accordance with their respective terms and with the
consent of the Plan Sponsor, shall be TCEH Assumed Executory Contracts or Unexpired Leases. 
 B. Claims Based on Rejection of Executory Contracts
or Unexpired Leases. 
 Unless otherwise provided by a Final Order of the Bankruptcy Court, all Proofs of Claim with respect to
Claims arising from the rejection of Executory Contracts or Unexpired Leases, pursuant to the Plan or the Confirmation Order, if any, must be Filed within 30 days after the later of: (1) the date of entry of an order of the Bankruptcy Court
(including the Confirmation Order) approving such rejection; and (2) the effective date of such rejection. Any Claims arising from the rejection of an Executory Contract or Unexpired Lease not Filed within such time will be automatically
disallowed, forever barred from assertion, and shall not be enforceable against the Debtors or the Reorganized Debtors, the Estates, or their property without the need for any objection by the Reorganized Debtors or further notice to, or action,
order, or approval of the Bankruptcy Court or any other Entity, and any Claim arising out of the rejection of the Executory Contract or Unexpired Lease shall be deemed fully satisfied, released, and discharged, notwithstanding anything in the
Schedules or a Proof of Claim to the contrary. All Allowed Claims arising from the rejection of the Debtors’ Executory Contracts or Unexpired Leases shall be classified as General Unsecured Claims against the applicable Debtor and shall be
treated in accordance with the Plan, unless a different security or priority is otherwise asserted in such Proof of Claim and Allowed in accordance with Article VII of the Plan. 

  
 84 

 C. Cure of Defaults for Assumed Executory Contracts and Unexpired Leases. 

Any monetary defaults under each Assumed Executory Contract or Unexpired Lease shall be satisfied, pursuant to section 365(b)(1) of the
Bankruptcy Code, by payment of the default amount in Cash on the Effective Date, subject to the limitation described below, or on such other terms as the parties to such Executory Contracts or Unexpired Leases may otherwise agree. In the event of a
dispute regarding (1) the amount of any payments to cure such a default, (2) the ability of the Reorganized Debtors or any assignee to provide “adequate assurance of future performance” (within the meaning of section 365 of
the Bankruptcy Code) under the Executory Contract or Unexpired Lease to be assumed, or (3) any other matter pertaining to assumption, the cure payments required by section 365(b)(1) of the Bankruptcy Code shall be made following the entry
of a Final Order resolving the dispute and approving the assumption. At least 14 days before the applicable Confirmation Hearing, the Debtors will provide for notices of proposed assumption and proposed cure amounts to be sent to applicable third
parties and for procedures for objecting thereto and resolution of disputes by the Bankruptcy Court. Any objection by a counterparty to an Executory Contract or Unexpired Lease to a proposed assumption or related cure amount must be Filed, served,
and actually received by the Debtors at least seven (7) days before the applicable Confirmation Hearing. Any counterparty to an Executory Contract or Unexpired Lease that fails to object timely to the proposed assumption or cure amount will be
deemed to have consented to such assumption or proposed cure amount. 
 Assumption of any Executory Contract or Unexpired Lease shall
result in the full release and satisfaction of any Claims or defaults, whether monetary or nonmonetary, including defaults of provisions restricting the change in control or ownership interest composition or other bankruptcy-related defaults,
arising under any Assumed Executory Contract or Unexpired Lease at any time before the effective date of assumption. Any Proofs of Claim Filed with respect to an Assumed Executory Contract or Unexpired Lease shall be deemed disallowed and
expunged, without further notice to or action, order, or approval of the Bankruptcy Court. 
 D. Preexisting Obligations to the Debtors under
Executory Contracts and Unexpired Leases. 
 Rejection of any Executory Contract or Unexpired Lease pursuant to the Plan or otherwise
shall not constitute a termination of preexisting obligations owed by the Executory Contract or Unexpired Lease counterparty or counterparties to the Debtors or the Reorganized Debtors, as applicable, under such Executory Contracts or Unexpired
Leases. 
 E. Indemnification Obligations. 

1. Indemnification Obligations of the TCEH Debtors and EFH Shared Services Debtors. 

Notwithstanding anything in the Plan to the contrary, each Indemnification Obligation or any TCEH Debtor or EFH Shared Services Debtor shall be
assumed by the applicable TCEH Debtor or EFH Shared Services Debtor, effective as of the Effective Date, pursuant to sections 365 and 1123 of the Bankruptcy Code or otherwise. Each such Indemnification Obligation shall remain in full force and
effect, shall not be modified, reduced, discharged, impaired, or otherwise affected in any way, and shall survive Unimpaired and unaffected, irrespective of when such obligation arose. 

The TCEH Debtors, Reorganized TCEH, EFH Shared Services Debtors, and Reorganized EFH Shared Services Debtors shall assume the Indemnification
Obligations for the current and former directors, officers, managers, employees, and other professionals of the TCEH Debtors and EFH Shared Services Debtors, as applicable, in their capacities as such; provided that the TCEH Debtors,
Reorganized TCEH, EFH Shared Services Debtors, and Reorganized EFH Shared Services Debtors shall not assume, and shall not have any liability for or any obligations in respect of, any Indemnification Obligations for the current and former directors,
officers, managers, employees, and other professionals of the EFH Debtors or EFIH Debtors, in their capacities as such, and the EFH Debtors, Reorganized EFH, EFIH Debtors, and Reorganized EFIH shall not assume, and shall not have any liability for
or any obligations in respect of, any Indemnification Obligations for the current and former directors, officers, managers, employees, and other professionals of the TCEH Debtors or the EFH Shared Services Debtors, in their capacities as such. 

Notwithstanding the foregoing, nothing shall impair the ability of the Reorganized TCEH Debtors and Reorganized EFH Shared Services Debtors,
as applicable, to modify indemnification obligations (whether in the bylaws, certificates or incorporate or formation, limited liability company agreements, other organizational or formation documents, board resolutions, indemnification agreements,
employment contracts, or otherwise) for acts or omissions arising after the Effective Date. 

  
 85 

 2. Indemnification Obligations of the EFH Debtors and EFIH Debtors. 

Notwithstanding anything in the Plan to the contrary, from and after the Effective Date, each Indemnification Obligation of any EFH Debtor or
EFIH Debtor shall be treated in accordance with Section [6.8] of the Merger Agreement. 
 Notwithstanding the foregoing, nothing shall
impair the ability of Reorganized EFH or Reorganized EFIH, as applicable, to modify indemnification obligations (whether in the bylaws, certificates or incorporate or formation, limited liability company agreements, other organizational or formation
documents, board resolutions, indemnification agreements, employment contracts, or otherwise) for acts or omissions arising after the Effective Date. 

F. Insurance Policies. 
 Each of the
Debtors’ Insurance Policies are treated as Executory Contracts under the Plan. Unless otherwise provided in the Plan, on the TCEH Effective Date, the TCEH Debtors and EFH Shared Services Debtors, as applicable, shall be deemed to have assumed
all insurance policies and any agreements, documents, and instruments relating to coverage of all insured Claims, and such Insurance Policies shall not be impaired in any way by the Plan or the Confirmation Order, but rather will remain valid and
enforceable in accordance with their terms. 
 Notwithstanding Article V.A.1 of the Plan, except to the extent that the Plan Sponsor elects,
in its sole discretion, to list an Insurance Policy (or Insurance Policies) on the EFH/EFIH Rejected Executory Contract and Unexpired Lease List, on the EFH Effective Date, the EFH Debtors and EFIH Debtors, as applicable, shall be deemed to have
assumed all insurance policies and any agreements, documents, and instruments relating to coverage of all insured Claims against the EFH Debtors or EFIH Debtors, as applicable, and such Insurance Policies shall not be impaired in any way by the Plan
or the Confirmation Order, but rather will remain valid and enforceable against the Reorganized EFH Debtors or Reorganized EFIH Debtors, as applicable, in accordance with their terms. 

G. Modifications, Amendments, Supplements, Restatements, or Other Agreements. 

Unless otherwise provided in the Plan, each Executory Contract or Unexpired Lease that is assumed shall include all modifications, amendments,
supplements, or restatements, thereto or thereof, if any, including all easements, licenses, permits, rights, privileges, immunities, options, rights of first refusal, and any other interests, unless any of the foregoing agreements have been
previously rejected or repudiated or is rejected or repudiated under the Plan. 
 Modifications, amendments, supplements, and restatements
to prepetition Executory Contracts and Unexpired Leases that have been executed by the Debtors during the Chapter 11 Cases shall not be deemed to alter the prepetition nature of the Executory Contract or Unexpired Lease, or the validity, priority,
or amount of any Claims that may arise in connection therewith. 
 H. Reservation of Rights. 

Neither the exclusion nor inclusion of any Executory Contract or Unexpired Lease on the Rejected Executory Contract and Unexpired Lease List or
the Assumed Executory Contract and Unexpired Lease List, nor anything contained in the Plan, shall constitute an admission by the Debtors that any such contract or lease is in fact an Executory Contract or Unexpired Lease or that any of the
Reorganized Debtors has any liability thereunder. If there is a dispute regarding whether a contract or lease is or was executory or unexpired at the time of assumption or rejection, the Debtors or the Reorganized Debtors, as applicable, shall have
30 days following entry of a Final Order resolving such dispute to alter its treatment of such contract or lease. 
 I. Nonoccurrence of Effective Date.

 In the event that the Effective Date does not occur with respect to a Debtor, the Bankruptcy Court shall retain jurisdiction with
respect to any request to extend the deadline for assuming or rejecting Unexpired Leases with respect to such Debtor pursuant to section 365(d)(4) of the Bankruptcy Code, unless such deadline(s) have expired. 

  
 86 

 J. Contracts and Leases Entered Into After the Petition Date. 

Contracts and leases entered into after the Petition Date by any Debtor, including any Assumed Executory Contracts or Unexpired Leases, will be
performed by the applicable Debtor or the applicable Reorganized Debtor liable thereunder in the ordinary course of their business. Accordingly, any such contracts and leases (including any Assumed Executory Contracts or Unexpired Leases) that have
not been rejected as of the date of the Confirmation Date shall survive and remain unaffected by entry of the Confirmation Order. 

ARTICLE VI. 
 PROVISIONS
GOVERNING DISTRIBUTIONS 
 A. Timing and Calculation of Amounts to Be Distributed. 

Unless otherwise provided in the Plan, on the Effective Date (or if a Claim or Interest is not an Allowed Claim or Allowed Interest on the
Effective Date, on the date that such Claim or Interest becomes an Allowed Claim or Allowed Interest, or as soon as reasonably practicable thereafter), each Holder of an Allowed Claim or Allowed Interest shall receive the full amount of the
distributions that the Plan provides for Allowed Claims and Allowed Interest in the applicable Class. In the event that any payment or act under the Plan is required to be made or performed on a date that is not a Business Day, then the making
of such payment or the performance of such act may be completed on the next succeeding Business Day, but shall be deemed to have been completed as of the required date. If and to the extent that there are Disputed Claims or Disputed Interests,
distributions on account of any such Disputed Claims or Disputed Interests shall be made pursuant to the provisions set forth in Article VII of the Plan. Except as otherwise provided in the Plan, Holders of Claims and Interests shall not be entitled
to interest, dividends, or accruals on the distributions provided for in the Plan, regardless of whether such distributions are delivered on or at any time after the Effective Date. For the avoidance of doubt, distributions to Holders of Allowed
Class C3 Claims shall be made in accordance with Article III.B.29 of the Plan, notwithstanding the pendency of the TCEH First Lien Creditor Deposit L/C Collateral Allocation Dispute. 

With respect to Holders of Class C5 Claims that are Allowed as of the TCEH Effective Date, the amount of the Effective Date distribution will
be calculated as if each Disputed Class C5 Claim were an Allowed Class C5 Claim equal to the lesser of (a) the asserted amount of such Claim and (b) the amount estimated by the Bankruptcy Court in accordance with Article VII.C of the Plan.
On each Periodic Distribution Date, the Disbursing Agent shall make additional Pro Rata distributions to Holders of Allowed Class C5 Claims until such Claims have received the maximum recovery available to Holders of Class C5 Claims under the Plan.

 Before the TCEH Effective Date, the TCEH Debtors shall create, in consultation with the TCEH Committee, a list of Disputed Class C5
Claims that shall be Allowed Class C5 Claims as of the TCEH Effective Date. Following the creation of such list, the TCEH Debtors shall, as soon as reasonably practicable thereafter submit, to the Bankruptcy Court an order, in form and substance
reasonably acceptable to the TCEH Committee, allowing such Claims; provided, however, that entry of such order shall not in any way impede, delay, or otherwise interfere with the occurrence of the TCEH Effective Date. 

Notwithstanding anything to the contrary in the Plan, including provisions providing for distributions to occur on the Effective Date or as
soon as reasonably practicable after the Effective Date, no distributions shall be made to Holders of Claims against the EFH Debtors or the EFIH Debtors, except certain distributions to take place on the EFH Effective Date as set forth in Article
IV.B.9 of the Plan, until: (a) all Claims against the EFH Debtors and the EFIH Debtors, excluding any Makewhole Claim that is either an EFIH First Lien Note Claim or an EFIH Second Lien Note Claim, have been resolved by Final Order pursuant to
Article VII of the Plan, (b) all Professional Fee Claims have been paid from the EFH Professional Fee Escrow Account and the EFIH Professional Fee Escrow Account and any amounts remaining in such accounts have been refunded to the EFH/EFIH
Distribution Account, in accordance with Article II.A.2(e), (c) the fees and expenses provided for in Article IV.R.1 and Article VI.C.1 of the Plan have been paid in full in Cash, and (d) the Post-Closing Audit has concluded according to
the terms of the Merger Agreement and all payments to or from the EFH/EFIH Distribution Account based on the results of the Post-

  
 87 

 
Closing Audit have been made. Any Makewhole Claim that is either an EFIH First Lien Note Claim or an EFIH Second Lien Note Claim and which is first Allowed after the EFH Effective Date shall be
paid in full, in Cash, by Reorganized EFIH in accordance with Article III.B.19 or III.B.20, as applicable, and such Cash shall not be subtracted from the EFH/EFIH Distribution Account. 

B. Rights and Powers of EFH Plan Administrator Board. 

The EFH Plan Administrator Board shall be authorized to direct the Disbursing Agent to make distributions from the EFH/EFIH Distribution
Account to Holders of Allowed Claims and Allowed Interests against the EFH Debtors and the EFIH Debtors on the EFH Effective Date, or as soon as reasonably practicable thereafter, in accordance with the Plan and to exercise such other powers as may
be vested in the EFH Plan Administrator Board by order of the Bankruptcy Court, pursuant to the Plan, or as deemed by the EFH Plan Administrator Board to be necessary and proper to implement the provisions of the Plan. The EFH Plan Administrator
Board shall not be required to give any bond or surety or other security for the performance of its duties unless otherwise ordered by the Bankruptcy Court. 

The EFH Plan Administrator Board or its professionals on behalf of the EFH Plan Administrator Board shall keep an accounting of distributions
made from, and funds contributed to, the EFH/EFIH Distribution Account that sets forth whether such distributions or contributions, as applicable, were made for the benefit of the EFH Debtors or their creditors, on the one hand, or the EFIH Debtors
on the other hand. 
 C. Disbursing Agent. 

All distributions under the Plan shall be made to Holders of Allowed Claims and Allowed Interests by the Disbursing Agent (including at the
direction of the EFH Plan Administrator Board, as applicable) on the applicable Effective Date, or as soon as reasonably practicable thereafter, in accordance with the Plan. The Disbursing Agent shall not be required to give any bond or surety
or other security for the performance of its duties unless otherwise ordered by the Bankruptcy Court. 
 D. Rights and Powers of Disbursing
Agent. 
 1. Powers of the Disbursing Agent. 

The Disbursing Agent shall be empowered to: (a) effect all actions and execute all agreements, instruments, and other documents necessary
to perform its duties under the Plan; (b) make all distributions contemplated hereby, including making distributions from the EFH/EFIH Distribution Account at the direction of the EFH Plan Administrator Board; (c) employ professionals to
represent it with respect to its responsibilities; and (d) exercise such other powers as may be vested in the Disbursing Agent by order of the Bankruptcy Court, pursuant to the Plan, or as deemed by the Disbursing Agent to be necessary and
proper to implement the provisions of the Plan. 
 2. Expenses Incurred On or After the Effective Date. 

Except as otherwise ordered by the Bankruptcy Court, the amount of any reasonable fees and expenses incurred by the Disbursing Agent in
performing its duties under the Plan on or after the Effective Date (including taxes) and any reasonable compensation and expense reimbursement claims (including reasonable attorney fees and expenses) made by the Disbursing Agent shall be paid in
Cash by the Reorganized Debtors. Reorganized TCEH and the Reorganized EFH Shared Services Debtors shall only be obligated to pay the reasonable fees and expenses incurred by the Disbursing Agent for distributions related to Claims against the TCEH
Debtors and the EFH Shared Services Debtors, and the Reorganized EFH Debtors and Reorganized EFIH Debtors shall only be obligated to pay the reasonable fees and expenses incurred by the Disbursing Agent for distributions related to Claims against
the EFH Debtors and EFIH Debtors. 

  
 88 

 E. Delivery of Distributions and Undeliverable or Unclaimed Distributions. 

1. Record Date for Distribution. 

On the Distribution Record Date, the Claims Register shall be closed and any party responsible for making distributions shall be authorized and
entitled to recognize only those record Holders listed on the Claims Register as of the close of business on the Distribution Record Date. The record Holder for the TCEH Credit Agreement Claims solely for purposes of the Distribution Record Date
shall be the TCEH First Lien Administrative Agent. 
 2. Delivery of Distributions in General. 

Except as otherwise provided herein, the Reorganized Debtors shall make distributions to Holders of Allowed Claims and Allowed Interests as of
the Distribution Record Date at the address for each such Holder as indicated on the Debtors’ records as of the date of any such distribution; provided, however, that the Distribution Record Date shall not apply to publicly-traded Securities.
The manner of such distributions shall be determined at the discretion of the Reorganized Debtors, and the address for each Holder of an Allowed Claim or Allowed Interest shall be deemed to be the address set forth in any Proof of Claim or Interest
Filed by that Holder. 
 3. Delivery of Distributions on DIP Claims. 

All distributions on account of DIP Claims shall be made to the applicable DIP Agent, who shall be deemed to be the Holder of such DIP Claims,
as applicable, for purposes of distributions to be made hereunder. As soon as practicable following compliance with the requirements set forth in this Article VI, the applicable DIP Agent shall arrange to deliver or direct the delivery of such
distributions to or on behalf of the Holders of DIP Claims in accordance with the terms of the DIP Facilities, as applicable, subject to any modifications to such distributions in accordance with the terms of the Plan; provided, however, that
the DIP Agents shall retain all rights as administrative agents under the DIP Facilities in connection with the delivery of distributions to DIP Lenders. The DIP Agents shall not have any liability to any person with respect to distributions made or
directed to be made by the DIP Agents. 
 4. Delivery of Distributions on TCEH First Lien Claims. 

To the extent that the TCEH First Lien Creditor Plan Distribution Allocation Order provides that any of the TCEH First Lien Creditor
Distributions are Collateral (as that term is used in the TCEH First Lien Intercreditor Agreement) or proceeds of Collateral (as that term is used in the TCEH First Lien Intercreditor Agreement), then such distributions shall be made to the TCEH
First Lien Collateral Agent for further distribution to the Secured Debt Representatives (as defined in the TCEH First Lien Intercreditor Agreement) pursuant to and in accordance with the Plan and the TCEH First Lien Creditor Plan Distribution
Allocation Order, and the Secured Debt Representatives (as defined in the TCEH First Lien Intercreditor Agreement) shall in turn make such distributions to the Holders of Allowed Class C3 Claims pursuant to and in accordance with the Plan and the
TCEH First Lien Creditor Plan Distribution Allocation Order. To the extent that the TCEH First Lien Creditor Plan Distribution Allocation Order provides that any of the TCEH First Lien Creditor Distributions are not Collateral (as that term is used
in the TCEH First Lien Intercreditor Agreement) or proceeds of Collateral (as that term is used in the TCEH First Lien Intercreditor Agreement), then such distributions shall be made to the Secured Debt Representatives (as defined in the TCEH First
Lien Intercreditor Agreement) for further distribution directly to the Holders of Allowed Class C3 Claims pursuant to and in accordance with the Plan. If the TCEH First Lien Creditor Plan Distribution Allocation Order has not been entered as of the
TCEH Effective Date, a reserve will be established in the manner described in Article III.B.29. For the avoidance of doubt, distributions to Holders of Allowed Class C3 Claims shall be made in accordance with Article III.B.29 of the Plan,
notwithstanding the pendency of the TCEH First Lien Creditor Deposit L/C Collateral Allocation Dispute. THE TCEH FIRST LIEN AGENT AND THE TCEH FIRST LIEN NOTES TRUSTEE SHALL NOT HAVE ANY LIABILITY TO ANY PERSON WITH RESPECT TO DISTRIBUTIONS MADE
OR DIRECTED TO BE MADE BY SUCH TCEH FIRST LIEN AGENT OR TCEH FIRST LIEN NOTES TRUSTEE PURSUANT TO AND IN ACCORDANCE WITH THE PLAN. 

  
 89 

 5. No Fractional Distributions. 

No fractional shares of Reorganized TCEH Common Stock, Reorganized EFH Common Stock, or NextEra Common Stock shall be distributed and no Cash
shall be distributed in lieu of such fractional amounts, except as provided in the Merger Agreement. When any distribution pursuant to the Plan on account of an applicable Allowed Claim would otherwise result in the issuance of a number of shares of
Reorganized TCEH Common Stock or Reorganized EFH Common Stock, that is not a whole number, the actual distribution of shares of Reorganized TCEH Common Stock or Reorganized EFH Common Stock shall be rounded as follows: (a) fractions of one-half ( 1⁄2) or greater shall be rounded to the next higher whole number and (b) fractions of less than one-half ( 1⁄2) shall be rounded to the next lower whole number with no further payment therefor. The total number of authorized shares of Reorganized TCEH Common Stock or
Reorganized EFH Common Stock to be distributed to Holders of Allowed Claims shall be adjusted as necessary to account for the foregoing rounding. 

6. Minimum Distribution. 
 No
Cash payment of less than $50.00 shall be made to a Holder of an Allowed Claim on account of such Allowed Claim. 
 7. Undeliverable
Distributions and Unclaimed Property. 
 In the event that any distribution to any Holder is returned as undeliverable, no distribution to
such Holder shall be made unless and until the Disbursing Agent has determined the then-current address of such Holder, at which time such distribution shall be made to such Holder without interest; provided, however, that such distributions shall
be deemed unclaimed property under section 347(b) of the Bankruptcy Code at the expiration of one year from the applicable Distribution Date. After such date, all unclaimed property or interests in property shall revert to the applicable Reorganized
Debtor(s) automatically and without need for a further order by the Bankruptcy Court (notwithstanding any applicable federal or state escheat, abandoned, or unclaimed property laws to the contrary), and the claim of any Holder to such property shall
be fully discharged, released, and forever barred. 
 8. Delivery of Distributions on PCRB Claims. 

All distributions on account of PCRB Claims are subject to the PCRB Trustee’s charging lien and priority of payment rights. Accordingly,
before the distribution of any Cash to Holders of Allowed PCRB Claims pursuant to Article III.B.30 of the Plan, the Disbursing Agent will distribute (solely from the distribution of Cash to Holders of Allowed PCRB Claims as set forth in Article
III.B.30 of the Plan) to the PCRB Trustee the amount of Cash that is necessary to pay in full (in accordance with the amount provided by the PCRB Trustee in a written notice to the Disbursing Agent) (a) the fees and expenses of the PCRB Trustee
(including professional and other advisory fees and expenses) that are not otherwise paid under the Plan and (b) any reserve for fees and expenses as requested by the PCRB Trustee (including any reserve required in the event of an appeal
relating to the PCRB Trustee’s fees and expenses otherwise payable under this Plan). The Disbursing Agent shall distribute Pro Rata the remainder of the Cash that is distributable on account of the PCRB Claims pursuant to Article III.B.30 of
the Plan to the Holders of the PCRB Claims pursuant to the Plan. The Disbursing Agent also shall distribute Pro Rata to the Holders of the PCRB Claims any unused portion of any reserve required by the PCRB Trustee upon the PCRB’s release of
such reserve to the Disbursing Agent. 
 F. Manner of Payment. 

Unless as otherwise set forth herein, all distributions of Cash, the Reorganized TCEH Common Stock, and the Reorganized EFH Common Stock to the
Holders of Allowed Claims under the Plan shall be made by the Disbursing Agent on behalf of the Reorganized Debtors, the Plan Sponsor, and Merger Sub. At the option of the Disbursing Agent, any Cash payment to be made under the Plan may be made by
check or wire transfer or as otherwise required or provided in applicable agreements. All Cash distributions to be made hereunder to the DIP Agents on account of the DIP Claims shall be made by wire transfer. 

  
 90 

 G. SEC Registration/Exemption. 

Each of the Reorganized TCEH Common Stock, New Reorganized TCEH Debt, Reorganized TCEH Sub Preferred Stock, Reorganized EFH Common Stock, and
NextEra Common Stock are or may be “securities,” as defined in Section 2(a)(1) of the Securities Act, section 101 of the Bankruptcy Code, and applicable state securities laws.

Pursuant to section 1145 of the Bankruptcy Code, the issuance of (1) the Reorganized TCEH Common Stock and (2) the Reorganized EFH
Common Stock are exempt from, among other things, the registration requirements of Section 5 of the Securities Act and any other applicable U.S. state or local law requiring registration before the offering, issuance, distribution, or sale of
such securities. Each of the Reorganized TCEH Common Stock and the Reorganized EFH Common Stock (a) is not a “restricted security” as defined in Rule 144(a)(3) under the Securities Act, and (b) is freely tradable and
transferable by any initial recipient thereof that (i) at the time of transfer, is not an “affiliate” of the Reorganized TCEH, Reorganized EFH, Reorganized EFIH, the Plan Sponsor, or Merger Sub, as the case may be, as defined in Rule
144(a)(1) under the Securities Act and has not been such an “affiliate” within 90 days of such transfer, and (ii) is not an entity that is an “underwriter” as defined in subsection (b) of section 1145 of the Bankruptcy
Code.
 The NextEra Common Stock issued in exchange for Reorganized EFH Common Stock may be issued without registration under the Securities
Act in reliance upon the exemption set forth in section 1145(a)(1) of the Bankruptcy Code for the offer or sale under a chapter 11 plan of a security of a successor to the debtor if such securities are offered or sold in exchange for a claim
against, or an interest in, such debtor. The EFH Debtors and EFIH Debtors, with the support of the Plan Sponsor, will seek to obtain a ruling from the Bankruptcy Court in the Confirmation Order that the section 1145(a)(1) exemption applies to the
NextEra Common Stock. In the event the Plan Sponsor is unable to obtain a ruling from the Bankruptcy Court that the issuance of the NextEra Common Stock qualifies for the statutory exemption from securities law provided under section 1145 of the
Bankruptcy Code, the Plan Sponsor will either rely on another exemption from the registration requirements of the Securities Act, use reasonable best efforts to seek a “no action” letter from the SEC seeking confirmation that the issuance
of the NextEra Common Stock is exempt from the registration requirements of the Securities Act and from applicable state securities laws, or will be required to register the issuance of the NextEra Common Stock under the Securities Act. 

The New Reorganized TCEH Debt and the Reorganized TCEH Sub Preferred Stock will be issued without registration under the Securities Act in
reliance on the exemption from the registration requirements of the Securities Act provided by section 4(a)(2) of the Securities Act (and/or Regulation D promulgated thereunder) and each will be “restricted securities” subject to resale
restrictions and may be resold, exchanged, assigned or otherwise transferred only pursuant to registration, or an applicable exemption from registration under the Securities Act and other applicable law. 

Should the Reorganized Debtors elect on or after the Effective Date to reflect any ownership of any of the Reorganized TCEH Common Stock, New
Reorganized TCEH Debt, Reorganized TCEH Sub Preferred Stock, Reorganized EFH Common Stock, and NextEra Common Stock through the facilities of the DTC, the Reorganized Debtors need not provide any further evidence other than the Plan or the
Confirmation Order with respect to the treatment of the Reorganized TCEH Common Stock, New Reorganized TCEH Debt, Reorganized TCEH Sub Preferred Stock, Reorganized EFH Common Stock, and NextEra Common Stock under applicable securities laws. 

The DTC shall be required to accept and conclusively rely upon the Plan and Confirmation Order in lieu of a legal opinion regarding whether
any of the Reorganized TCEH Common Stock, New Reorganized TCEH Debt, Reorganized TCEH Sub Preferred Stock, Reorganized EFH Common Stock, and NextEra Common Stock, as applicable, are exempt from registration and/or eligible for DTC book-entry
delivery, settlement, and depository services. 
 Notwithstanding anything to the contrary in the Plan, no entity (including, for the
avoidance of doubt, the DTC) may require a legal opinion regarding the validity of any transaction contemplated by the Plan, including, for the avoidance of doubt, whether the Reorganized TCEH Common Stock, New Reorganized TCEH Debt, Reorganized
TCEH Sub Preferred Stock, Reorganized EFH Common Stock, and NextEra Common Stock are exempt from registration and/or eligible for DTC book-entry delivery, settlement, and depository services. 

  
 91 

 H. Compliance with Tax Requirements. 

In connection with the Plan, the applicable Reorganized Debtor(s) shall comply with all tax withholding and reporting requirements imposed on
them by any Governmental Unit with respect to distributions pursuant to the Plan. Notwithstanding any provision herein to the contrary, the Reorganized Debtors and the Disbursing Agent, as applicable, shall be authorized to take all actions
necessary to comply with such withholding and reporting requirements, including liquidating a portion of the distribution to be made under the Plan to generate sufficient funds to pay applicable withholding taxes, withholding distributions pending
receipt of information necessary to facilitate such distributions, and establishing any other mechanisms they believe are reasonable and appropriate to comply with such requirements. The Reorganized Debtors reserve the right to allocate all
distributions made under the Plan in compliance with all applicable wage garnishments, alimony, child support, and other spousal awards, liens, and encumbrances. 

I. No Postpetition or Default Interest on Claims. 

Unless otherwise specifically provided for in the Plan or the Confirmation Order, and notwithstanding any documents that govern the
Debtors’ prepetition funded indebtedness to the contrary, (1) postpetition and/or default interest shall not accrue or be paid on any Claims and (2) no Holder of a Claim shall be entitled to: (a) interest accruing on or after the
Petition Date on any such Claim; or (b) interest at the contract default rate, as applicable. 
 J. Setoffs and Recoupment. 

The Debtors and Reorganized Debtors, as applicable, may, but shall not be required to, setoff against or recoup any payments or distributions
to be made pursuant to the Plan in respect of any Claims of any nature whatsoever that the Debtors or the Reorganized Debtors may have against the claimant, but neither the failure to do so nor the allowance of any Claim hereunder shall constitute a
waiver or release by the Debtors or the Reorganized Debtors of any such claim it may have against the Holder of such Claim. 
 K. No Double Payment of
Claims. 
 To the extent that a Claim is Allowed against more than one Debtor’s Estate, there shall be only a single recovery on
account of that Allowed Claim, but the Holder of an Allowed Claim against more than one Debtor may recover distributions from all co-obligor Debtors’ Estates until the Holder has received payment in full on the Allowed Claims. No Holder of an
Allowed Claim shall be entitled to receive more than payment in full of its Allowed Claim, and each Claim shall be administered and treated in the manner provided by the Plan only until payment in full on that Allowed Claim. 

L. Claims Paid or Payable by Third Parties. 

1. Claims Paid by Third Parties. 

The Debtors or the Reorganized Debtors, as applicable, shall reduce a Claim, and such Claim shall be disallowed without a Claims objection
having to be Filed and without any further notice to or action, order, or approval of the Bankruptcy Court, to the extent that the Holder of such Claim receives payment on account of such Claim from a party that is not a Debtor or a Reorganized
Debtor (other than the Disbursing Agent). Subject to the last sentence of this paragraph, to the extent a Holder of a Claim receives a distribution on account of such Claim and receives payment from a party that is not a Debtor or a Reorganized
Debtor on account of such Claim, such Holder shall, within 14 days of receipt thereof, repay or return the distribution to the applicable Reorganized Debtor, to the extent the Holder’s total recovery on account of such Claim from the third
party and under the Plan exceeds the amount of such Claim as of the date of any such distribution under the Plan. The failure of such Holder to timely repay or return such distribution shall result in the Holder owing the applicable Reorganized
Debtor annualized interest at the Federal Judgment Rate on such amount owed for each Business Day after the 14-day period specified above until the amount is repaid. 

  
 92 

 2. Claims Payable by Third Parties. 

No distributions under the Plan shall be made on account of an Allowed Claim that is payable pursuant to one of the Debtors’ insurance
policies until the Holder of such Allowed Claim has exhausted all remedies with respect to such insurance policy. To the extent that one or more of the Debtors’ insurers agrees to satisfy in full or in part a Claim (if and to the extent
adjudicated by a court of competent jurisdiction), then immediately upon such insurers’ agreement, the applicable portion of such Claim may be expunged without a Claims objection having to be Filed and without any further notice to or action,
order, or approval of the Bankruptcy Court. 
 3. Applicability of Insurance Policies. 

Except as otherwise provided in the Plan, distributions to Holders of Allowed Claims shall be in accordance with the provisions of any
applicable insurance policy. Except as otherwise expressly provided in the Plan, nothing contained in the Plan shall constitute or be deemed a waiver of any Cause of Action that the Debtors or any Entity may hold against any other Entity, including
insurers under any policies of insurance, nor shall anything contained herein (a) constitute or be deemed a waiver by such insurers of any rights or defenses, including coverage defenses, held by such insurers, or (b) establish, determine,
or otherwise imply any liability or obligation, including any coverage obligation, of any insurer. 
 ARTICLE VII. 

PROCEDURES FOR RESOLVING CONTINGENT, 

UNLIQUIDATED, AND DISPUTED CLAIMS 
 A.
Allowance of Claims. 
 Except as otherwise set forth in the Plan, after the Effective Date, each of the Reorganized Debtors shall have
and retain any and all rights and defenses such Debtor had with respect to any Claim immediately before the Effective Date. This Article VII of the Plan shall not apply to the DIP Claims, TCEH First Lien Claims, TCEH Second Lien Note Claims, or TCEH
Unsecured Note Claims, which Claims shall be Allowed in full and shall not be subject to any avoidance, reductions, set off, offset, recharacterization, subordination (whether equitable, contractual, or otherwise), counterclaims, cross-claims,
defenses, disallowance, impairment, objection, or any other challenges under any applicable law or regulation by any person or entity. 

Except as specifically provided as Allowed Claims pursuant to Article III.B of the Plan or otherwise objected to by the Debtors in the Chapter
11 Cases, the Plan shall serve as the Debtors’ objection to all other EFIH First Lien Note Claims, EFIH Second Lien Note Claims, EFIH Unsecured Note Claims, EFH LBO Note Claims, and EFH Legacy Note Claims under the respective indentures. If the
Bankruptcy Court sustains the Debtors’ objection to these Claims, the Confirmation Order shall disallow such Claims. The Holders of such Claims may respond to the Debtors’ objection to such Claims by filing an objection to the Plan. 

B. Claims Administration Responsibilities. 

Except as otherwise specifically provided in the Plan, after the Effective Date, the applicable Reorganized Debtor(s) shall have the sole
authority: (1) to File, withdraw, or litigate to judgment, objections to Claims; (2) to settle or compromise any Disputed Claim without any further notice to or action, order, or approval by the Bankruptcy Court; and (3) to administer
and adjust the Claims Register to reflect any such settlements or compromises without any further notice to or action, order, or approval by the Bankruptcy Court. 

Except with respect to Claims and Causes of Action released by the Debtors pursuant to the releases and exculpations contained in the Plan,
including in Article VIII, if one or more Entities have sought and obtained standing to prosecute a Cause of Action on behalf of one or more of the Debtors’ Estates and such Entities are prosecuting such Causes of Actions as of the Effective
Date, then such Entities will have the sole authority, solely with respect to such Causes of Action, to File, withdraw, litigate to judgment, settle, compromise, or take any other actions in respect of such Causes of Action. 

  
 93 

 C. Estimation of Claims. 

Before or after the Effective Date, the Debtors or the Reorganized Debtors, as applicable, with the consent of the Plan Sponsor with respect to
any Dispute Claim against any EFH Debtor or any EFIH Debtor, may (but are not required to) at any time request that the Bankruptcy Court estimate any Disputed Claim that is contingent or unliquidated pursuant to section 502(c) of the Bankruptcy Code
for any reason, regardless of whether any party previously has objected to such Claim or whether the Bankruptcy Court has ruled on any such objection, and the Bankruptcy Court shall retain jurisdiction to estimate any such Claim, including during
the litigation of any objection to any Claim or during the appeal relating to such objection. Notwithstanding any provision to the contrary in the Plan, a Claim that has been expunged from the Claims Register, but that either is subject to appeal or
has not been the subject of a Final Order, shall be deemed to be estimated at zero dollars, unless otherwise ordered by the Bankruptcy Court. In the event that the Bankruptcy Court estimates any contingent or unliquidated Claim, that estimated
amount shall constitute a maximum limitation on such Claim for all purposes under the Plan (including for purposes of distributions), and the relevant Reorganized Debtor may elect to pursue any supplemental proceedings to object to any ultimate
distribution on such Claim. 
 If the TCEH Debtors determine, in their reasonable discretion and in consultation with the TCEH Committee,
that (1) one or more Disputed Class C5 Claims are capable of estimation by the Bankruptcy Court, (2) estimation will materially improve TCEH Effective Date distributions to Holders of Allowed Class C5 Claims, and (3) estimation is
otherwise in the best interests of the Estates, the TCEH Debtors shall file one or more motions to estimate such Disputed Class C5 Claims, which motion or motions shall be filed and noticed to be heard (on regular notice to all parties in interest)
by the Bankruptcy Court before the TCEH Effective Date (or such other date as determined by the Bankruptcy Court). 
 D. Adjustment to Claims without
Objection. 
 Any Claim that has been paid or satisfied, or any Claim that has been amended or superseded, may be adjusted or expunged on
the Claims Register by the Reorganized Debtors without a Claims objection having to be Filed and without any further notice to or action, order, or approval of the Bankruptcy Court. 

E. Time to File Objections to Claims or Interests. 

Any objections to Claims or Interests shall be Filed on or before the Claims Objection Deadline. 

F. Disallowance of Claims. 
 Any Claims
held by Entities from which the Bankruptcy Court has determined that property is recoverable under section 542, 543, 550, or 553 of the Bankruptcy Code or that is a transferee of a transfer that the Bankruptcy Court has determined is avoidable under
section 522(f), 522(h), 544, 545, 547, 548, 549, or 724(a) of the Bankruptcy Code, shall be deemed disallowed pursuant to section 502(d) of the Bankruptcy Code, and Holders of such Claims may not receive any distributions on account of such Claims
until such time as such Causes of Action against that Entity have been settled or a Bankruptcy Court order with respect thereto has been entered and the full amount of such obligation to the Debtors has been paid or turned over in full. All Proofs
of Claim Filed on account of an Indemnification Obligation shall be deemed satisfied and expunged from the Claims Register as of the Effective Date to the extent such Indemnification Obligation is assumed (or honored or reaffirmed, as the case may
be) pursuant to the Plan, without any further notice to or action, order, or approval of the Bankruptcy Court. All Proofs of Claim Filed on account of an employee benefit shall be deemed satisfied and expunged from the Claims Register as of the
Effective Date to the extent the Reorganized Entities elect to honor such employee benefit, without any further notice to or action, order, or approval of the Bankruptcy Court. 

Except as provided herein or otherwise agreed, any and all Proofs of Claim Filed after the Bar Date shall be deemed disallowed and expunged
as of the Effective Date without any further notice to or action, order, or approval of the Bankruptcy Court, and Holders of such Claims may not receive any distributions on account of such Claims, unless on or before the Confirmation Hearing such
late Claim has been deemed timely Filed by a Final Order. 

  
 94 

 G. Amendments to Proofs of Claim. 

On or after the Effective Date, a Proof of Claim or Interest may not be Filed or amended without the prior authorization of the Bankruptcy
Court or the Reorganized Debtors, and any such new or amended Proof of Claim or Interest Filed shall be deemed disallowed in full and expunged without any further action. 

H. Reimbursement or Contribution. 
 If the
Bankruptcy Court disallows a Claim for reimbursement or contribution of an Entity pursuant to section 502(e)(1)(B) of the Bankruptcy Code, then to the extent that such Claim is contingent as of the time of allowance or disallowance, such Claim shall
be forever disallowed and expunged notwithstanding section 502(j) of the Bankruptcy Code, unless before the Confirmation Date: (1) such Claim has been adjudicated as non-contingent; or (2) the
relevant Holder of a Claim has Filed a non-contingent Proof of Claim on account of such Claim and a Final Order has been entered before the Confirmation Date determining such Claim as no longer contingent. 

I. No Distributions Pending Allowance. 

Except as otherwise set forth herein, if an objection to a Claim or portion thereof is Filed as set forth in Article VII.A and VII.B of the
Plan, no payment or distribution provided under the Plan shall be made on account of such Disputed Claim or portion thereof unless and until such Disputed Claim becomes an Allowed Claim. 

J. Distributions After Allowance. 
 To the
extent that a Disputed Claim ultimately becomes an Allowed Claim, distributions (if any) shall be made to the Holder of such Allowed Claim in accordance with the provisions of the Plan. Except as otherwise set forth in the Plan, as soon as
practicable after the date that the order or judgment of the Bankruptcy Court allowing any Disputed Claim becomes a Final Order, the Disbursing Agent shall provide to the Holder of such Claim the distribution (if any) to which such Holder is
entitled under the Plan as of the Effective Date, less any previous distribution (if any) that was made on account of the undisputed portion of such Claim, without any interest, dividends, or accruals to be paid on account of such Claim unless
required under such order or judgment of the Bankruptcy Court. 
 ARTICLE VIII.

pursuant to section 501 of the Bankruptcy Code; (2) a Claim or Interest based upon such debt, right, or Interest is Allowed pursuant to section 502 of the Bankruptcy Code; or (3) the Holder of such a Claim or Interest has accepted the
Plan. Any default or “event of default” by the Debtors or Affiliates with respect to any Claim or Interest that existed immediately before or on account of the Filing of the Chapter 11 Cases shall be deemed cured (and no longer continuing)

Plan (and, with respect to any Allowed Other Secured Claims of the Texas Comptroller which the Debtors shall Reinstate on the Effective Date), all mortgages, deeds of trust, Liens, pledges, or other security interests against any property of the
Estates shall be fully released and discharged, and all of the right, title, and interest of any Holder of such mortgages, deeds of trust, Liens, pledges, or other security interests shall revert to the Reorganized Debtors and their successors and
assigns, in each case, without any further approval or order of the Bankruptcy Court and without any action or Filing being required to be made by the Debtors.

 96 

 
Settlement Claim shall be treated, released, and discharged on the EFH Effective Date. Notwithstanding anything to the contrary in the foregoing, the claims and Causes of Action set forth in
Section 6.12 of the Parent Disclosure Letter delivered in connection with the Merger Agreement shall not be released or discharged. 
 D.

 As of the Effective Date, each Releasing Party is deemed to have released and
discharged each Debtor, Reorganized Debtor, and Released Party from any and all Claims and Causes of Action, including Claims and Causes of Action identified, claimed, or released in the Standing Motions, the Litigation Letters, or the Disinterested
Directors Settlement, as well as all other Claims and Causes of Action, whether known or unknown, including any derivative claims, asserted on behalf of the Debtors, that such Entity would have been legally entitled to assert (whether individually

party who brings a claim or Cause of Action against the Plan Sponsor in connection with the Debtors’ pursuit of regulatory approvals under the Original Confirmed Plan. Notwithstanding anything to the contrary in the foregoing, and for the
avoidance of doubt, the TCEH Settlement Claim shall be treated, released, and discharged on the EFH Effective Date. 

  
 97 

 E. Exculpation. 

Except as otherwise specifically provided in the Plan (including Article III.B.19, III.B.20, and III.B.22), no Exculpated Party shall have
or incur liability for, and each Exculpated Party is hereby released and exculpated from, any Cause of Action for any claim related to any act or omission in connection with, relating to, or arising out of, the Chapter 11 Cases, the formulation,
preparation, dissemination, negotiation, Filing, or termination of the Terminated Restructuring Support Agreement and related prepetition transactions, the Disclosure Statement, the Plan, the Plan Support Agreement, the New EFH/EFIH Plan Support
Agreement, the EFH/EFIH Committee Settlement, the Original Confirmed Plan, the Transaction Agreements, or any Restructuring Transaction, contract, instrument, release or other agreement or document (including providing any legal opinion requested by
any Entity regarding any transaction, contract, instrument, document, or other agreement contemplated by the Plan or the reliance by any Exculpated Party on the Plan or the Confirmation Order in lieu of such legal opinion) created or entered into in
connection with the Disclosure Statement, the Plan, the Original Confirmed Plan, the Plan Support Agreement, the New EFH/EFIH Plan Support Agreement, the EFH/EFIH Committee Settlement, the Transaction Agreements, or the DIP Facilities, the Filing of
the Chapter 11 Cases, the pursuit of Confirmation, the pursuit of Consummation, the administration and implementation of the Plan, including the issuance of Securities pursuant to the Plan, or the distribution of property under the Plan, the
Transaction Agreements, or any other related agreement, except for claims related to any act or omission that is determined in a final order to have constituted actual fraud, willful misconduct, or gross negligence, but in all respects such Entities
shall be entitled to reasonably rely upon the advice of counsel with respect to their duties and responsibilities pursuant to the Plan. The Exculpated Parties have, and upon completion of the Plan shall be deemed to have, participated in good faith
and in compliance with the applicable laws with regard to the solicitation of, and distribution of, consideration pursuant to the Plan and, therefore, are not, and on account of such distributions shall not be, liable at any time for the violation
of any applicable law, rule, or regulation governing the solicitation of acceptances or rejections of the Plan or such distributions made pursuant to the Plan. For the avoidance of doubt, notwithstanding anything to the contrary in the foregoing,
the exculpation set forth above does not exculpate any (i) claims or Causes of Action by the Holders of TCEH First Lien Claims, the TCEH First Lien Agent, or the TCEH First Lien Notes Trustee against one or more Holders of TCEH First Lien
Claims, the TCEH First Lien Agent, or the TCEH First Lien Notes Trustee arising from or in connection with the TCEH First Lien Creditor Allocation Disputes, or (ii) claims or Causes of Action asserted by any Holder of Allowed Class C3 Claims
against one or more Holders of Allowed Class C3 Claims (other than the TCEH First Lien Agent, except in the TCEH First Lien Agent’s capacity as a nominal defendant to declaratory judgment claims in respect of which no monetary recovery is
sought) solely with respect to the TCEH First Lien Creditor Deposit L/C Collateral Allocation Dispute. 
 F. Injunction. 

In addition to any injunction provided in the Settlement Order, except as otherwise expressly provided in the Plan or for obligations issued
or required to be paid pursuant to the Plan or the Confirmation Order, all Entities that have held, hold, or may hold Claims or Interests that have been released pursuant to Article VIII.C or Article VIII.D of the Plan, shall be discharged pursuant
to Article VIII.A of the Plan, or are subject to exculpation pursuant to Article VIII.E of the Plan, are permanently enjoined, from and after the Effective Date, from taking any of the following actions against, as applicable, the Debtors, the
Reorganized Debtors, or the Released Parties: (i) commencing or continuing in any manner any action or other proceeding of any kind on account of or in connection with or with respect to any such claims or interests; (ii) enforcing,
attaching, collecting, or recovering by any manner or means any judgment, award, decree, or order against such Entities on account of or in connection with or with respect to any such claims or interests; (iii) creating, perfecting, or
enforcing any lien or encumbrance of any kind against such Entities or the property or the estates of such Entities on account of or in connection with or with respect to any such claims or interests; (iv) asserting any right of setoff,
subrogation, or recoupment of any kind against any obligation due from such Entities or against the property of such Entities on account of or in connection with or with respect to any such claims or interests unless such Entity has timely asserted
such setoff right in a document Filed with the Bankruptcy Court explicitly preserving such setoff, and notwithstanding an indication of a claim or interest or otherwise that such Entity asserts, has, or intends to preserve any right of setoff
pursuant 

  
 98 

 
to applicable law or otherwise; and (v) commencing or continuing in any manner any action or other proceeding of any kind on account of or in connection with or with respect to any such
claims or interests released or settled pursuant to the Plan. For the avoidance of doubt, notwithstanding anything to the contrary in the foregoing, the injunction set forth above does not enjoin (a) the TCEH First Lien Creditor Allocation
Disputes, or any claims or Causes of Action by the Holders of TCEH First Lien Claims, the TCEH First Lien Agent, or the TCEH First Lien Notes Trustee against one or more Holders of TCEH First Lien Claims, the TCEH First Lien Agent, or the TCEH First
Lien Notes Trustee arising from or in connection with the TCEH First Lien Creditor Allocation Disputes, or (b) the TCEH First Lien Creditor Deposit L/C Collateral Allocation Dispute, or claims or Causes of Action asserted in the Marathon
Delaware Action (in accordance with and as that term is defined in the Stipulation and Consent Order Regarding Limited Objection of Marathon Asset Management, LP to Confirmation of Debtors’ Fifth Amended Plan of Reorganization,
dated November 10, 2015 [Docket No. 6932]) by any Holder of Allowed Class C3 Claims against one or more Holders of Allowed Class C3 Claims (other than the TCEH First Lien Agent, except in the TCEH First Lien Agent’s capacity as
a nominal defendant to declaratory judgment claims in respect of which no monetary recovery is sought) solely with respect to the TCEH First Lien Creditor Deposit L/C Collateral Allocation Dispute. Notwithstanding anything to the contrary in the
foregoing, the Plan shall not enjoin any party from pursuing the claims and Causes of Action set forth in Section 6.12 of the Parent Disclosure Letter delivered in connection with the Merger Agreement. 

G. Liabilities to, and Rights of, Governmental Units. 

Nothing in the Plan or the Confirmation Order shall release, discharge, or preclude the enforcement of: (i) any liability to a
Governmental Unit that is not a Claim; (ii) any Claim of a Governmental Unit arising on or after the Effective Date, other than taxes determined under the prompt determination procedure in section 505 of the Bankruptcy Code, to the extent
applicable; (iii) any liability to a Governmental Unit on the part of any Entity other than the Debtors or Reorganized Debtors; or (iv) any valid right of setoff or recoupment by any Governmental Unit. 

H. Environmental Law Matters. 
 Nothing in
the Plan or the Confirmation Order shall release, discharge, or preclude the enforcement of (or preclude, release, defeat, or limit the defense under non-bankruptcy law of): (i) any liability under Environmental Law to a Governmental Unit that
is not a Claim; (ii) any Claim under Environmental Law of a Governmental Unit arising on or after the Effective Date; (iii) any liability under Environmental Law to a Governmental Unit on the part of any Entity to the extent of such
Entity’s liability under non-bankruptcy law on account of its status as owner or operator of such property after the Effective Date; (iv) any liability to a Governmental Unit on the part of any Entity other than the Debtors or Reorganized
Debtors; or (v) any valid right of setoff or recoupment by any Governmental Unit. All parties’ rights and defenses under Environmental Law with respect to (i) through (v) above are fully preserved. For the avoidance of doubt, the
United States is not a Releasing Party under the Plan. 
 Nothing in the Plan or the Confirmation Order shall enjoin or otherwise bar any
Governmental Unit from asserting or enforcing, outside this Court, any liability described in the preceding paragraph. Nothing in the Plan or the Confirmation Order authorizes: (i) the transfer or assignment of any governmental license, permit,
registration, authorization, or approval, or (ii) the discontinuation of any obligation thereunder, without compliance with all applicable legal requirements under Environmental Law. The Bankruptcy Court retains jurisdiction, but not
exclusive jurisdiction, to determine whether environmental liabilities asserted by any Governmental Unit are discharged or otherwise barred by the Confirmation Order or the Plan, or the Bankruptcy Code. 

For the avoidance of doubt, all Claims under Environmental Law arising before the Effective Date, including penalty claims for days of
violation prior to the Effective Date, shall be subject to Article VIII of the Plan and treated in accordance with the Plan in all respects and the Bankruptcy Court shall retain jurisdiction as provided in Article XI of the Plan in relation to the
allowance or disallowance of any Claim under Environmental Law arising before the Effective Date. 
 Without limiting the Bankruptcy
Court’s jurisdiction as set forth above, nothing in the Plan or the Confirmation Order shall divest or limit the jurisdiction of other tribunals over the Environmental Action, and upon the Effective Date of the Plan, the Environmental Action
shall survive the Chapter 11 Cases and may be adjudicated 

  
 99 

 
in the court or tribunal in which such Environmental Action is currently pending; provided, further, however, any judgment for a Claim in the Environmental Action arising
before the Effective Date shall be treated in accordance with the Plan in all respects; provided, further, however, that nothing in the Plan shall preclude, release, defeat, or limit any grounds for asserting or opposing an
alleged defense or affirmative defense under non-bankruptcy law in the Environmental Action based on any change in ownership, and all such grounds for asserting or opposing such defenses and affirmative defenses under non-bankruptcy law are
expressly preserved. With respect to the Environmental Action, this Article VIII.H does not alter any rights or defenses under non-bankruptcy law arising as a result of any changes of ownership provided in the Plan or the Confirmation Order. The
Governmental Units reserve all rights as to whether there are any such rights or defenses. 
 I. Protections Against Discriminatory Treatment. 

Consistent with section 525 of the Bankruptcy Code and the Supremacy Clause of the U.S. Constitution, all Entities, including Governmental
Units, shall not discriminate against the Reorganized Debtors or deny, revoke, suspend, or refuse to renew a license, permit, charter, franchise, or other similar grant to, condition such a grant to, discriminate with respect to such a grant
against, the Reorganized Debtors, or another Entity with whom the Reorganized Debtors have been associated, solely because each Debtor has been a debtor under chapter 11 of the Bankruptcy Code, has been insolvent before the commencement of the
Chapter 11 Cases (or during the Chapter 11 Cases but before the Debtors are granted or denied a discharge), or has not paid a debt that is dischargeable in the Chapter 11 Cases. 

J. Recoupment. 
 In no event shall any
Holder of Claims or Interests be entitled to recoup any Claim against any claim, right, or Cause of Action of the Debtors or the Reorganized Debtors, as applicable, unless such Holder actually has performed such recoupment and provided notice
thereof in writing to the Debtors on or before the Confirmation Date, notwithstanding any indication in any Proof of Claim or Proof of Interest or otherwise that such Holder asserts, has, or intends to preserve any right of recoupment. 

K. Document Retention. 
 On and after the
Effective Date, the Reorganized Debtors may maintain documents in accordance with their standard document retention policy, as may be altered, amended, modified, or supplemented by the Reorganized Debtors.

Services Debtors, including, in the case of any Conflict Matter between any Debtors, each Debtor acting at the direction of its respective Disinterested Director or Manager and without the consent of any other Debtor, with the consent of the TCEH
Supporting First Lien Creditors (such consent not to be unreasonably withheld); provided, that in the event the condition to Consummation set forth in Article IX.C.8 is not satisfied, the TCEH Debtors may nevertheless consummate the Taxable
Separation and the TCEH Effective Date may occur so long as the other conditions to Confirmation and Consummation have been satisfied or waived in accordance with this Article IX.E; provided further that in no event shall either of the
conditions set forth in Article IX.C.6 or IX.C.8 be waived without the consent of the Plan Sponsor. 

  
 105 

 The conditions to Confirmation with respect to the EFH Debtors and the EFIH Debtors and the EFH
Effective Date set forth in Articles IX.B.1 through IX.B.3, IX.D.1 through IX.D.5, IX.D.12, and IX.D.14 through IX.D.16 may be waived subject to the consent of each of (a) the EFH Debtors, (b) the EFIH Debtors, and (c) the Plan
Sponsor, including, in the case of any Conflict Matter between any Debtors, each Debtor acting at the direction of its respective Disinterested Director or Manager and without the consent of any other Debtor. The conditions to EFH Effective Date set
forth in Articles IX.D.7, IX.D.8, IX.D.10, IX.D.11, and IX.D.13 may be waived by the Plan Sponsor in its sole and absolute discretion. The conditions to the EFH Effective Date set forth in Article IX.D.6 and IX.D.9 may not be waived pursuant to this
Article IX.E, but may only be waived pursuant to waiver rights expressly provided therein, if any. 
 F. Effect of Failure of Conditions. 

Unless extended by the Debtors, including, in the case of any Conflict Matter between any Debtors, each Debtor acting at the direction of its
respective Disinterested Director or Manager and without the consent of any other Debtor, if the Effective Date does not occur before one year following Confirmation, with respect to a particular Debtor, then, as to such particular Debtor:
(1) the Plan shall be null and void in all respects; (2) any settlement or compromise embodied in the Plan, assumption or rejection of Executory Contracts or Unexpired Leases effected under the Plan, and any document or agreement executed
pursuant to the Plan, shall be deemed null and void; and (3) nothing contained in the Plan shall: (a) constitute a waiver or release of any Claims, Interests, or Causes of Action; (b) prejudice in any manner the rights of such Debtor
or any other Entity; or (c) constitute an admission, acknowledgement, offer, or undertaking of any sort by such Debtor or any other Entity. Notwithstanding the foregoing, for the avoidance of doubt, (i) the Settlement embodied in the
Settlement Agreement shall remain in full force and effect and the failure of Confirmation or Consummation to occur with respect to any or all Debtors shall not affect the Settlement or any provisions of the Settlement Agreement and (ii) if the
Spin-Off is effectuated, the Approval Order shall remain in full force and effect and the failure of Confirmation or Consummation to occur with respect to any Debtor (other than a TCEH Debtor) shall not affect the Approval Order or the Tax Matters
Agreement. 
 G. Certain IRS Matters. 

The Plan provides that as a condition precedent to the TCEH Effective Date in the event of a Spin-Off, the Private Letter Ruling obtained by
the Debtors is in full force and effect and shall not have been revoked or withdrawn and that the requirements in the Merger Agreement with respect to the Supplemental Rulings shall have been satisfied.

Nothing in the Plan (or subsequently amended Plan) or the Confirmation Order shall be deemed to waive the right of the IRS to object to
confirmation of a subsequently amended Plan or alternative chapter 11 plan to the extent the U.S. would be entitled to object to confirmation under applicable law, including to the extent that the Debtors choose to go forward with a chapter 11 plan
that is premised on a taxable separation of TCEH from EFH Corp. and not a tax-free reorganization within the meaning of Section 368(a)(1)(G) of the Internal Revenue Code. Specifically, the Debtors may not oppose the U.S.’s objection
on the grounds of failure to file an earlier objection, equitable mootness, laches, estoppel, or a similar theory. The U.S. may move for a stay of the Effective Date in conjunction with its objection, and the Debtors’ right to object to
any such motion are preserved. 
 Nothing in the Plan (or subsequently amended Plan) or Confirmation Order shall affect the rights of the
IRS or United States to assess or collect a tax arising on or after the Confirmation Date against Reorganized EFH, any member of its consolidated group, and/or any successor entities as permitted under applicable law.

Conflict Matter between any Debtors, each Debtor acting at the direction of its respective Disinterested Director or Manager and without the consent of any other Debtor, reserves the right to
modify the Plan, one or more times, before Confirmation, whether such modification is material or immaterial, and to seek Confirmation consistent with the Bankruptcy Code. Subject to certain restrictions and requirements set forth in section 1127 of
the Bankruptcy Code and Bankruptcy Rule 3019, each of the Debtors, including, in the case of any Conflict Matter between any Debtors, each of the Debtors acting at the direction of its respective Disinterested Director or Manager and without
the consent of any other Debtor, expressly reserves its respective rights to alter, amend, or modify the Plan, one or more times, after Confirmation and, to the extent necessary, may initiate proceedings in the Bankruptcy Court to so alter, amend,
or modify the Plan, or remedy any defect or omission, or reconcile any inconsistencies in the Plan, the Disclosure Statement, or the Confirmation Order, including with respect to such modifications. Any alteration, amendment, or modification to the
Plan shall be in accordance with the Plan Support Agreement and the New EFH/EFIH Plan Support Agreement and in form and substance reasonably acceptable to (i) the Plan Sponsor (both with respect to (a) the Plan of the EFH Debtors and EFIH
Debtors, it being understood that it shall be reasonable for the Plan Sponsor to deem unacceptable any alteration, amendment, or modification that (1) results in the imposition or reinstatement of any Claim against or Interest in the
Reorganized EFH Debtors, the Reorganized EFIH Debtors, the Plan Sponsor, or any Affiliate of the Plan Sponsor or (2) alters any consent right in favor of the Reorganized EFH Debtors, the Reorganized EFIH Debtors, the Plan Sponsor, or any
Affiliate of the Plan Sponsor, and (b) the Plan of the TCEH Debtors and EFH Shared Services Debtors, but only to the extent that such alteration, amendment, or modification affects the rights or liabilities of the Reorganized EFH Debtors, the
Reorganized EFIH Debtors, the Plan Sponsor, or any Affiliate of the Plan Sponsor), (ii) the TCEH Supporting First Lien Creditors (with respect to the Plan of the TCEH Debtors and EFH Shared Services Debtors), and (iii) the DIP Agents (and

EFH Notes Trustee. 
 B. Effect of Confirmation on Modifications. 

Entry of a Confirmation Order shall mean that each alteration, amendment, or modification to the Plan since the solicitation thereof are
approved pursuant to section 1127(a) of the Bankruptcy Code and do not require additional disclosure or resolicitation under Bankruptcy Rule 3019; provided, however, that each alteration, amendment, or modification shall be made in
accordance with Article X.A of the Plan. 
 C. Revocation or Withdrawal of Plan. 

1. Revocation or Withdrawal of the Plan with Respect to the TCEH Debtors and EFH Shared Services Debtors. 

Subject to the Plan Support Agreement, the New EFH/EFIH Plan Support Agreement, and the Merger Agreement, each of the TCEH Debtors and
EFH Shared Services Debtors, including, in the case of any Conflict Matter between any Debtors, each TCEH Debtor or EFH Shared Services Debtor acting at the direction of its respective Disinterested Director or Manager and without the consent of any
other Debtor, reserves the right to revoke or withdraw the Plan as it applies to the TCEH Debtors and EFH Shared Services Debtorsbefore the Confirmation Date and to File subsequent plans for any reason, including to the extent the Debtors receive a
higher or otherwise better offer than what is provided for in the Plan, or if pursuing Confirmation of the Plan would be inconsistent with any Debtor’s fiduciary duties; provided, however, that the Debtors shall not seek to revoke
or withdraw the Plan with respect to the TCEH Debtors without the consent of the TCEH Supporting First Lien Creditors (such consent not to be unreasonably withheld); provided further, however, that the Debtors may withdraw support of
the Plan with respect to the TCEH Debtors without any party’s consent.  
 2. Revocation or Withdrawal of the Plan with Respect
to the EFH Debtors and EFIH Debtors. 
 Each EFH Debtor and EFIH Debtor reserves the right to revoke or withdraw the Plan as it applies to
the EFH Debtors and the EFIH Debtors only to the extent permitted by the terms of the New EFH/EFIH Plan Support Agreement and the Merger Agreement. 

  
 107 

 3. Consequence of Withdrawal of the Plan. 

If any of the Debtors revoke or withdraw the Plan, or if Confirmation or Consummation does not occur, then: (1) the Plan shall be null and
void in all respects; (2) any settlement or compromise embodied in the Plan (other than the Settlement embodied in the Settlement Agreement), assumption or rejection of Executory Contracts or Unexpired Leases effected under the Plan, and any
document or agreement executed pursuant to the Plan, shall be deemed null and void; and (3) nothing contained in the Plan shall: (a) constitute a waiver or release of any Claims, Interests, or Causes of Action; (b) prejudice in any
manner the rights of such Debtor or any other Entity; or (c) constitute an admission, acknowledgement, offer, or undertaking of any sort by such Debtor or any other Entity. Notwithstanding the foregoing and for the avoidance of doubt,
(i) the Settlement embodied in the Settlement Agreement shall remain in full force and effect and the failure of Confirmation or Consummation to occur with respect to any or all Debtors shall not affect the Settlement or any provisions of the
Settlement Agreement and (ii) if the Spin-Off is effectuated, the Approval Order shall remain in full force and effect and the failure of Confirmation or Consummation to occur with respect to any Debtor (other than a TCEH Debtor) shall not

 After the
Effective Date, the Reorganized Debtors have authority to send a notice to Entities that to continue to receive documents pursuant to Bankruptcy Rule 2002, such Entity must File a renewed request to receive documents pursuant to Bankruptcy Rule
2002. After the Effective Date, the Reorganized Debtors are authorized to limit the list of Entities receiving documents pursuant to Bankruptcy Rule 2002 to those Entities who have Filed such renewed requests. 

I. Term of Injunctions or Stays. 
 Unless
otherwise provided in the Plan or the Confirmation Order, all injunctions or stays in effect in the Chapter 11 Cases pursuant to sections 105 or 362 of the Bankruptcy Code or any order of the Bankruptcy Court, and extant on the Confirmation Date
(excluding any injunctions or stays contained in the Plan or the Confirmation Order) shall remain in full force and effect until the Effective Date. All injunctions or stays contained in the Plan or the Confirmation Order shall remain in full
force and effect in accordance with their terms. 
 J. Entire Agreement. 

Except as otherwise indicated, the Plan supersedes all previous and contemporaneous negotiations, promises, covenants, agreements,
understandings, and representations on such subjects, all of which have become merged and integrated into the Plan. 

  
 113 

 K. Exhibits. 

All exhibits and documents included in the Plan Supplement are incorporated into and are a part of the Plan as if set forth in full in the
Plan. After the exhibits and documents are Filed, copies of such exhibits and documents shall be available upon written request to the Debtors’ counsel at the address above or by downloading such exhibits and documents from the Debtors’
restructuring website at http://www.efhcaseinfo.com or the Bankruptcy Court’s website at www.deb.uscourts.gov. 
 L. Nonseverability of Plan
Provisions. 
 If, before Confirmation, any term or provision of the Plan is held by the Bankruptcy Court to be invalid, void, or
unenforceable, the Bankruptcy Court shall have the power to alter and interpret such term or provision to make it valid or enforceable to the maximum extent practicable, consistent with the original purpose of the term or provision held to be
invalid, void, or unenforceable, and such term or provision shall then be applicable as altered or interpreted; provided that in no event shall the Plan Sponsor be required to consummate any of the transactions contemplated to be consummated
at the Merger Closing unless the conditions to the Plan Sponsor’s consummation of such transactions shall have been satisfied or waived in accordance with the Merger Agreement. Notwithstanding any such holding, alteration, or interpretation,
the remainder of the terms and provisions of the Plan will remain in full force and effect and will in no way be affected, impaired, or invalidated by such holding, alteration, or interpretation. The Confirmation Order shall constitute a judicial
determination and shall provide that each term and provision of the Plan, as it may have been altered or interpreted in accordance with the foregoing, is: (1) valid and enforceable pursuant to its terms; (2) integral to the Plan and may
not be deleted or modified without the Debtors’ or Reorganized Debtors’ consent, as applicable; and (3) nonseverable and mutually dependent. Notwithstanding anything in this Plan to the contrary, the Plan may be confirmed and
consummated as to the TCEH Debtors and the EFH Shared Services Debtors separate from, and independent of, any confirmation or consummation of this Plan as to any of the EFH Debtors or EFIH Debtors. 

M. Votes Solicited in Good Faith. 
 Upon
entry of the Confirmation Order, the Debtors will be deemed to have solicited votes on the Plan in good faith and in compliance with the Bankruptcy Code, and pursuant to section 1125(e) of the Bankruptcy Code, the Debtors and each of their
respective Affiliates, agents, representatives, members, principals, shareholders, officers, directors, managers, employees, advisors, and attorneys will be deemed to have participated in good faith and in compliance with the Bankruptcy Code in the
offer, issuance, sale, and purchase of Securities offered and sold under the Plan and any previous plan, and, therefore, neither any of such parties or individuals or the Reorganized Debtors will have any liability for the violation of any
applicable law (including the Securities Act), rule, or regulation governing the solicitation of votes on the Plan or the offer, issuance, sale, or purchase of the Securities offered and sold under the Plan and any previous plan. 

N. Waiver or Estoppel. 
 Each Holder of a
Claim or Interest shall be deemed to have waived any right to assert any argument, including the right to argue that its Claim or Interest should be Allowed in a certain amount, in a certain priority, Secured or not subordinated by virtue of an
agreement made with the Debtors or their counsel, or any other Entity, if such agreement was not disclosed in the Plan, the Disclosure Statement, or papers Filed before the Confirmation Date. 

O. Conflicts. 
 Except as set forth
in the Plan, to the extent that any provision of the Disclosure Statement, the Plan Supplement, the Merger Agreement, or any agreement or order (other than the Confirmation Order) referenced in the Plan (or any exhibits, schedules, appendices,
supplements, or amendments to any of the foregoing), conflict with or are in any way inconsistent with any provision of the Plan, the Plan shall govern and control; provided, however, with respect to any conflict or inconsistency
between the Plan and the Confirmation Order, the Confirmation Order shall govern; provided further, however, that in no event shall the Plan Sponsor be required to consummate any of the transactions contemplated to be consummated at the Merger
Closing unless the conditions to the Plan Sponsor’s consummation of such transactions shall have been satisfied or waived in accordance with the Merger Agreement.

 Exhibit B 

Offer 
 (See Attached)

  
 Exhibit B 

 Exhibit C 

IPO Conversion Plan 
 The following
constitutes the “IPO Conversion Plan” that is expected to be implemented in connection with or following the Merger at the election of NextEra Energy, Inc. (“Parent”) and its implementation shall constitute an “IPO
Conversion” as such term is defined in the Investor Rights Agreement. The IPO Conversion Plan may be amended, modified or supplemented from time to time by Parent subject to the prior written consent of the Company and EFIH (such consent not to
be unreasonably withheld, conditioned or delayed). Capitalized terms used herein and not otherwise expressly defined shall have the meaning set forth in the Agreement and Plan of Merger. 

 

	 	1.	Parent will form a new entity (“IPO Corp”), which will initially be wholly-owned and controlled, either directly or indirectly through Affiliate(s), by Parent. 

 

	 	2.	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. 

 

	 	3.	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. 

  

	 	4.	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”). 

  

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

  

	 	6.	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 

 Exhibit D 

Asbestos Escrow Agreement 

(See Attached) 

  
 Exhibit D 

 Exhibit E 

Key Regulatory Terms 
 The specific
package of terms and undertakings to be included in the application for the PUCT Approval in connection with the transactions contemplated by the Agreement or the Plan of Reorganization have not yet been finalized, however, the PUCT Approval
application will contain in any event 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. 

 

	 	2.	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. 

  

	 	3.	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, Moody’s, or Fitch credit ratings agencies, Oncor shall not use the lower credit rating as a justification for a higher regulatory
rate of return. 

  

	 	4.	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 (“SAIFI”) 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 SAIFI 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. 

  

	 	7.	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. 

  
 Exhibit E 

	 	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 staff of the PUCT 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 identified in 17 below, 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 Oncor, (i) 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 Purchase Transactions, and (ii) whether a termination of employment that occurs with respect to such employee constitutes a termination for “good reason” or “without cause” will be determined under the
terms of such Assumed Plan. Notwithstanding the foregoing, Oncor shall request each of such executives to execute a valid and non-revocable waiver 

  
 Exhibit E 

	 	
of his or her right to terminate his or her employment for an event specified under items (c) and (f) of the definitions of “Good Reason” specified in the Third Amended and
Restated Oncor Executive Change in Control Policy or “Good Reason” specified in the Oncor Amended and Restated Key Employee Change in Control Policy, as applicable. 

 

	 	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. 

  
 Exhibit E 

	 	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, Moody’s, or Fitch credit rating agencies determine that Oncor’s issuer/corporate credit rating is not investment grade.

 SCHEDULE I 

POST-RETIREMENT WELFARE BENEFITS 

WHEREAS, that certain Agreement entered into by and between TXU Electric Delivery Company, a Texas corporation, and TXU Energy Company LLC, a
Delaware limited liability company, dated March 10, 2005 (the “Original Agreement”) set forth certain provisions regarding the allocation to Oncor of a portion of the cost for post-retirement welfare benefits to be provided to Split
Participants (which benefits are currently provided under the Oncor Retiree Welfare Plan but which benefits may be provided through a successor plan to the Oncor Retiree Welfare Plan in the future (such plan, together with any such successor plan
(but not including the OSPP (as defined below)), collectively referred to as the “Oncor Plan”)) to certain current and future eligible Split Participants as listed on Exhibit A to the Administration Manual (as defined in Section 4
below) who are eligible for a retiree benefits subsidy as of the date hereof, as such Exhibit A may be amended from time to time in accordance with the provisions of the Administration Manual (the “Oncor Plan Split Participants”); 

WHEREAS, that certain Split Participant Agreement entered into by and between Oncor and EFH, dated April 28, 2014 and effective
July 1, 2014 (the “2014 Agreement”) modified the Original Agreement; 
 WHEREAS, pursuant to the Original Agreement, as
modified by the 2014 Agreement, Oncor is obligated to fund that portion of the welfare benefit costs for the Oncor Plan Split Participants with respect to such Oncor Plan Split Participants’ service allocated to Oncor under the Aon Hewitt
Welfare Letter, and EFH is obligated to fund the remaining welfare benefit costs of the Oncor Plan Split Participants, in each case, less the Oncor Plan Split Participants’ contributions; 

WHEREAS, pursuant to the 2014 Agreement, beginning on January 1, 2015, Oncor began administering the Oncor Plan, and EFH agreed to pay
Oncor for EFH’s portion of the costs associated with providing welfare benefits coverage for the Oncor Plan Split Participants (including certain administrative costs); 

WHEREAS, as a result of the Separation and the Transfer, Oncor and RTCEH will not be under “common control” within the meaning of
Section 414(c) of the Internal Revenue Code of 1986, as amended (the “Code”), or part of a “control group” within the meaning of Section 3(40)(B)(ii) of the Employee Retirement Income Security Act of 1974, as amended
(“ERISA”); 
 WHEREAS, as a result of the lack of common control under ERISA, among other things, the Oncor Plan could be a
multiple employer welfare arrangement as defined in Section 3(40) of ERISA (a “MEWA”) treated as self-insured for purposes of the Texas Insurance Code if both RTCEH and Oncor were to continue to fund the Oncor Plan as described in the
2014 Agreement beyond the Separation and Transfer; 

  
 5 

 WHEREAS, the Parties desire to amend and restate within this Schedule I the 2014 Agreement to:
(a) provide for the establishment of a separate post-retirement welfare benefit plan for the benefit of the Oncor Plan Split Participants that is a “fully-insured” plan; (b) permit the subsequent conversion of such fully-insured
plan to a “self-funded” or “partially-funded” plan if a written and binding advisory opinion from the Employee Benefits Security Administration of the U.S. Department of Labor (“DOL”) is issued to the effect that the
Oncor Split Participant Plan is not a MEWA as defined in 3(40) of ERISA (such “fully-insured” and/or “self-funded” or “partially-funded” plan is hereinafter referred to as the “Oncor Split Participant Plan” or
“OSPP”); and (c) set forth the funding obligations of RTCEH and Oncor under the OSPP; and WHEREAS, it is the intention of the Parties that RTCEH’s and Oncor’s obligations with respect to the costs of post-retirement welfare
benefits for the Oncor Plan Split Participants under the OSPP shall continue to be allocated in a manner consistent with the past practices of Oncor and EFH under the Oncor Plan prior to the Separation and the Transfer and in accordance with the Aon
Hewitt Welfare Letter. 
 NOW, THEREFORE, the Parties hereby agree as follows: 

 

	 	1.	Transition Period. Oncor will continue to provide medical (including prescription drug coverage), vision, life insurance and dental benefits to the Oncor Plan Split Participants, to the extent eligible,
under the Oncor Plan, on the same terms and conditions as heretofore provided under the Oncor Plan (including on a self-insured basis for purposes of medical, prescription drug, and dental coverage) through the last day of the calendar year
following the year of the Separation and Transfer, or such earlier date as determined in Oncor’s discretion (the “Transition Period”), provided however, that Oncor shall have given advance written notice to RTCEH of such
earlier date not less than ninety (90) days prior to such date. During the Transition Period, RTCEH shall pay its portion of (i) the aggregate benefit obligation costs, subject to the cap established by EFH in 2012 (as further described in
the Administration Manual (as defined below) and the memorandum from Aon Hewitt to EFH, dated August 7, 2015 (the “Aon Memorandum”), attached hereto as Exhibit I-B), with respect to medical, prescription drug, vision, life
insurance and dental benefits for each Oncor Plan Split Participant, and (ii) the Administrative Costs (as defined below), each of the foregoing as allocated pursuant to the Aon Hewitt Welfare Letter and historical practice between Oncor and
EFH except, in each instance, as may be provided otherwise in the Administration Manual. During the Transition Period, RTCEH shall not amend or terminate the amount of its contribution (determined consistent with the Aon Hewitt Welfare Letter) that
it provides for Oncor Plan Split Participant benefit obligation costs. 

  

	 	2.	Establishment of Separate Oncor Split Participant Plan. 

  

	 	a.	Effective no later than immediately following the end of the Transition Period, Oncor shall have established, with insurers selected by Oncor, a separate fully-insured post-retirement welfare benefit plan for the Oncor
Plan Split Participants and shall have transferred the liabilities associated with such fully-insured plan from the Oncor Plan to the OSPP. 

  
 6 

	 	b.	At any time, either Party may apply for a written and binding advisory opinion from the DOL to the effect that the OSPP or a similar alternative post-retirement welfare benefit arrangement is not, or would not be, a
MEWA. In the event that such requested advisory opinion is obtained to the reasonable satisfaction of the Parties, the Parties may mutually agree to convert the funding status of the OSPP from a fully-insured arrangement to a “self-funded”
or “partially-funded” arrangement. 

  

	 	3.	Coverage and Benefits under the Oncor Split Participant Plan. 

  

	 	a.	No later than immediately following the end of the Transition Period, to the extent an Oncor Plan Split Participant is or would otherwise become eligible for medical (including prescription drug coverage), vision,
dental, and life insurance benefits under the Oncor Plan according to its terms in effect as of the end of the Transition Period, such Oncor Plan Split Participant shall be or will become eligible for such benefits under the OSPP. Subject to
Section 9, Oncor shall use commercially reasonable efforts to offer benefits under the OSPP that are in the aggregate substantially equivalent to those benefits offered to former Oncor employees who are retirees under the Oncor Plan
(“Substantial Coverage Equivalence”); provided, however that Oncor’s obligations pursuant to this sentence shall be deemed satisfied if it (i) determines, in its sole but good faith judgment, that no available insurance product
provides Substantial Coverage Equivalence and (ii) offers an insurance product that, in its sole but good faith judgment, provides benefits that are as close as reasonably possible to Substantial Coverage Equivalence. The determination of
Substantial Coverage Equivalence shall not take into account any incremental cost attributable to the OSPP’s status as a fully-insured plan when compared to the Oncor Plan’s status as a self-insured arrangement. Oncor shall be deemed to
comply with this Section 3(a) if both: (i) Oncor determines, in its sole but good faith judgment, that the cost to the Oncor Plan Split Participants of benefits that provide Substantial Coverage Equivalence is unduly burdensome to the
Oncor Plan Split Participants, and (ii) Oncor instead provides such benefit options based on and reflecting the Oncor Subsidy (as defined below) that, in Oncor’s sole but good faith judgment, are collectively in the best interests of the
Oncor Plan Split Participants. Nothing in this Section 3 shall diminish Oncor’s obligations under Section 9. 

  

	 	b.	 As further set forth in the Administration Manual, Oncor shall timely provide to RTCEH information on the
benefits and coverages to be provided under the OSPP, including any changes in benefits, as compared to the benefits provided to former Oncor employees who are retirees under the Oncor Plan. Any active employees who will be eligible for benefits
under the OSPP following retirement will not be eligible for such benefits under any welfare plans maintained by RTCEH after retirement so long as this Schedule I is in effect. Active employees who are future eligible Oncor Plan Split Participants
shall continue to be credited with service for purposes of determining the premium subsidies provided to them by 

  
 7 

	 	
Oncor and RTCEH for post-retirement welfare benefits in accordance with the practice in effect for such crediting of service as of the date of this Agreement. Oncor shall for all purposes,
including those relating to the Oncor Plan Split Participants, be the sponsor of the OSPP, and Oncor or its designee shall be the plan administrator for the OSPP. In no event shall Oncor be (i) limited in any way in offering benefits to
participants under any of its other plans as it determines, in its sole but good faith judgment, or (ii) required to incur any expense related to benefits offered to Oncor Plan Split Participants that is greater than has been determined
reasonable by the Public Utility Commission of Texas pursuant to Section 36.065 of the Texas Utilities Code (the Public Utility Regulatory Act (PURA)). 

  

	 	4.	Allocation of Costs under the Oncor Plan and the Oncor Split Participant Plan. 

  

	 	a.	The Aon Hewitt Welfare Letter describes the current and past practices of allocating the costs associated with providing post-retirement welfare benefit coverage for the Oncor Plan Split Participants between Oncor and
EFH, including the practices prior to the Separation and the Transfer, and the Parties agree that such practices will be continued by RTCEH and Oncor following the Separation and the Transfer for so long as this Schedule I is in effect except as
otherwise provided herein or in the Administration Manual. RTCEH and Oncor will each continue to pay its own portion of the costs (including Administrative Costs, as defined below) associated with providing welfare benefit coverage for the Oncor
Plan Split Participants according to the allocations set forth in the Aon Hewitt Welfare Letter subject to both: (i) as to the RTCEH portion of the costs, the cap described in the Administration Manual and the Aon Memorandum; and (ii) the
ability of RTCEH and Oncor to reduce the amount of their respective contributions in accordance with the provisions described in this Agreement. 

  

	 	b.	Following the Transition Period, RTCEH shall not amend or terminate the amount of the contribution it provides for Oncor Plan Split Participant premium subsidies unless it provides at least one hundred fifty
(150) days’ notice to Oncor and such advanced notice to Oncor Plan Split Participants as required by any applicable law of such amendment or termination, and provided that such amendment or termination may only become effective as of the
first day of a plan year. RTCEH shall be fully responsible for any additional administrative expenses that may be incurred by Oncor as a result of RTCEH’s amendment and termination of the premium subsidies it provides to the Oncor Plan Split
Participants. 

  

	 	c.	 For each plan year that the OSPP is a fully-insured arrangement, RTCEH will pay Oncor for RTCEH’s share of
the costs associated with providing post- retirement welfare benefits to the Oncor Plan Split Participants (including the annual premium, Administrative Costs and the Overhead Fee, as defined below) calculated using the methodologies described in
the Aon Hewitt Welfare Letter in accordance with the procedures set forth in this Section 4 and the administration manual attached hereto as Exhibit I-C containing details regarding the operations and administration of the Oncor Plan
during the Transition Period and the OSPP following the Transition 

  
 8 

	 	
Period, developed and mutually agreed to by the Parties and as amended from time to time by written consent of the Parties to the extent specified therein (the “Administration Manual”).
Oncor shall invoice RTCEH monthly for RTCEH’s monthly premium subsidy, and monthly share of the Administrative Costs and Overhead Fee. Each invoice shall have sufficient details as to the Administrative Costs as to allow RTCEH to identify and
reconcile its share of the Administrative Costs. RTCEH will pay Oncor any undisputed amount of an invoice within thirty (30) days of receipt and disputed amounts shall be reconciled in accordance with the dispute resolution process set forth in
the Administration Manual. 

  

	 	d.	As further set forth in the Administration Manual, Oncor will perform periodic true-up calculations of RTCEH’s aggregate premium subsidies paid to Oncor. Oncor will notify RTCEH in writing of the results of these
true-up calculations promptly after the calculations are completed and will, upon request, provide RTCEH with the information relied upon to make its calculations. As further set forth in the Administration Manual, Oncor will also perform periodic
true-up calculations of RTCEH’s share of the Administrative Costs paid to Oncor. Oncor shall keep and retain full and accurate records relating to the calculation of RTCEH’s aggregate premium subsidies, the Administrative Costs including
RTCEH’s allocable share of such costs, vendor invoices, insurance carrier statements and any true-up calculations (the “SPA Records”). Oncor shall preserve such SPA Records for each calendar year for seven (7) calendar years
following the end of such calendar year. During such period, RTCEH or its agents shall have the right, at RTCEH’s sole expense, to review such SPA Records during Oncor’s normal business hours, provided that such right may be exercised by
RTCEH no more than once per calendar year. For any year that the OSPP is a self-insured arrangement or is a partially fully-insured and partially self-insured arrangement, the Parties agree that the terms of the Administration Manual shall govern
the payment, subsidy and true-up calculations associated with the OSPP. Any disputed amounts shall be reconciled in accordance with the dispute resolution process set forth in the Administration Manual, provided, however, that RTCEH must
notify Oncor of any disputed amounts by within two (2) years after receipt of a true-up calculation. After two (2) years from receipt of a true-up calculation, RTCEH may not dispute any item in such true-up calculation and Oncor will have
no obligation to make any reimbursements pursuant to such true-up calculation. 

  

	 	e.	 For purposes of this Schedule I, “Administrative Costs” shall mean with respect to the plan under which
the Oncor Plan Split Participants are being provided with post-retirement welfare benefits, the total annual amount of administrative costs and expenses incurred by Oncor, relating to Oncor Plan Split Participants, in sponsoring, maintaining and
administering the Oncor Plan or the OSPP (as applicable), including without limitation, proportionate costs associated with communications to Oncor Plan Split Participants, third party vendor/benefit provider administrative costs and costs of legal
compliance (e.g., preparing Form 5500s, summaries of benefits and coverage, summary plan descriptions, summary annual reports and other applicable reporting and disclosure requirements), set-up and other costs associated with creating and adopting
the OSPP, costs associated with developing an open 

  
 9 

	 	
enrollment process for Oncor Plan Split Participants and calculating premium subsidies, and external actuarial, legal, consulting and accounting fees and costs of Oncor in sponsoring, maintaining
and administering the Oncor Plan or the OSPP (as applicable). 

  

	 	f.	Commencing on January 1 following the date of this Agreement, in addition to the Administrative Costs described above, RTCEH will pay Oncor an annual administration fee as set forth in the Administration Manual to
cover a portion of administrative overhead expenses Oncor incurs with respect to maintenance of the Oncor Plan or the OSPP (as applicable) (the “Overhead Fee”). 

 

	 	5.	Administration. Oncor shall in all respects be responsible for the customary administration of retiree welfare benefits for the Oncor Plan Split Participants. For the avoidance of doubt, such
administration services shall include but may not be limited to: benefit distributions; vendor selection, oversight and management; benefits strategy and plan design; participant communications, including but not limited to those required by law;
benefit accounting and claims processing; issue resolution; IRS Form W-2 processing for group term life insurance coverage; Retiree Club communications and inquiries; participant data and records management; selection and rollout of technology and
support; and engagement of actuarial, accounting, consulting and legal services related to the Oncor Plan, OSPP, and any other arrangement by which Oncor provides the Oncor Subsidy. Oncor agrees that it will give RTCEH a reasonable opportunity to
preview all participant communications created by or under Oncor’s direction that relate to material plan changes or amendments prior to the distribution of such communications to the Oncor Plan Split Participants. Notwithstanding anything in
this Agreement to the contrary, RTCEH will be responsible for any initial communications to Oncor Plan Split Participants regarding any reduction in or termination of its payment of premium subsidies for post-retirement welfare benefits provided
under the Oncor Plan or the OSPP (as applicable) on behalf of Oncor Plan Split Participants. RTCEH agrees that it will give Oncor a reasonable opportunity to preview any such communications prior to the distribution of such communications to the
Oncor Plan Split Participants and will notify Oncor of the anticipated distribution date for such communications. Oncor agrees that it will send to RTCEH a copy of all communications provided to Oncor Plan Split Participants contemporaneous with the
distribution of such communications to such Oncor Plan Split Participants. 

  

	 	6.	 Oncor Plan and OSPP Amendment, Modification or Termination. Nothing in this Schedule I shall be
deemed to constitute a provision of, or an amendment to the Oncor Plan, OSPP or any other benefit plan maintained by either Oncor or RTCEH. During the Transition Period, Oncor agrees it will not materially amend or modify (with an amendment or
modification being deemed material only if such amendment or modification would require Oncor to send a summary of material modifications to participants under applicable law) or terminate the Oncor Plan or, if applicable, the OSPP with respect to
the benefits available to the Oncor Plan Split Participants, other than as contemplated herein or as required by applicable law, without the written consent of RTCEH, which consent will not be unreasonably withheld. Subject to the requirements of
Section 9 herein, in the event that either (i) RTCEH reduces the amount of the contribution 

  
 10 

	 	
that it provides for Oncor Plan Split Participant benefits under the OSPP by 50% or more as compared to the contributions of EFH as of immediately before the date of this Agreement (a “50%
RTCEH Subsidy Reduction”) or (ii) RTCEH fails to make any payment due under this Schedule I (including the Administration Manual) within ninety (90) days of its due date, Oncor may, in its sole and absolute discretion, modify or
terminate the OSPP. 

  

	 	7.	No Third Party Beneficiary Rights. Nothing in this Schedule I shall create any third party beneficiary rights for any individual, including without limitation, any Oncor Plan Split Participant or his/her
dependents, nor shall this Schedule I be deemed to provide any Oncor Plan Split Participant or dependent, or any other individual, with any right to continued coverage under the OSPP or any other plan of Oncor or RTCEH. This Schedule I relates
solely to the Oncor Plan Split Participants and does not affect Oncor’s welfare benefit obligations related to any participant who is not an Oncor Plan Split Participant. 

 

	 	8.	Schedule I Amendment, Modification, or Termination. 

  

	 	a.	This Schedule I may be amended or terminated by written agreement of the Parties. 

  

	 	b.	This Schedule I will automatically terminate in the event that Oncor terminates the Oncor Plan during the Transition Period or each of the Oncor Plan, the OSPP, and any alternative arrangement provided under
Section 9 following the Transition Period. 

  

	 	c.	Without limiting the generality of the foregoing, in the event that RTCEH shall fail to pay the contribution that it provides for Oncor Plan Split Participant benefits within: (i) thirty (30) days of its due
date, Oncor may, subject to any limitations set forth in the Administration Manual, invoice the Oncor Plan Split Participants for such amounts unpaid by RTCEH, and (ii) ninety (90) days of its due date, Oncor may terminate the OSPP and
provide benefits to such Oncor Plan Split Participants from and after the date of the OSPP termination pursuant to Section 9 below. 

  

	 	9.	Oncor’s Post-Separation and Transfer Obligation. Notwithstanding any other provision in this Agreement to the contrary, Oncor shall after the Separation and Transfer offer an arrangement under which
Oncor shall provide a subsidy (“Oncor Subsidy”) for post-retirement medical (including prescription drug coverage) and life insurance benefits for Oncor Plan Split Participants, as applicable, for as long as Oncor offers such benefits and
provides a per-participant subsidy for such benefits to retirees under the Oncor Plan. If upon (i) a 50% RTCEH Subsidy Reduction or (ii) a failure of RTCEH to make any payment due under this Schedule I (including the Administration Manual)
within ninety (90) days of its due date, Oncor terminates the OSPP pursuant to Section 6 or Section 8(c), for as long as Oncor offers such benefits and provides a per-participant subsidy for such benefits to retirees under the Oncor
Plan, Oncor shall determine the benefits to be offered to Oncor Plan Split Participants in its sole and absolute discretion under this Section 9 (which shall in all events include the Oncor Subsidy and may include cash payments to the Oncor
Plan Split Participants equal to the Oncor Subsidy in lieu of the provision of any post-retirement benefits), and Sections 3 and 6 shall have no further force or effect. 

  
 11 

	 	10.	Cooperation. The Parties agree to cooperate with each other in any reasonable manner to carry out the terms of this Agreement. RTCEH acknowledges and agrees that in order to facilitate operation of the
Oncor Plan and the OSPP, as the case may be, Oncor will need information from RTCEH with respect to each Oncor Plan Split Participant who retired or retires from RTCEH or its affiliates and their predecessors, and RTCEH agrees to provide such
information to Oncor in the manner and at the times specified in the Administration Manual. Oncor acknowledges and agrees that Oncor shall provide to RTCEH information required to fulfill its obligations under this Agreement, including, without
limitation, Oncor Plan Split Participant contact information, information regarding plan amendments, actuarial data, and accounting information, on an annual basis, or more frequently upon request as may be further specified in the Administration
Manual. The Parties agree to work together in good faith, as necessary, to implement an appropriate approach that satisfies any new regulatory requirements applicable to the OSPP in the future. 

  
 12 

 SCHEDULE II 

RETIREMENT PLAN OBLIGATIONS 

WHEREAS, the Parties acknowledge that, pursuant to the Plan, RTCEH has assumed the EFH Retirement Plan from EFH and as a result RTCEH
sponsors, maintains and administers (or, if applicable, will sponsor, maintain and administer) the EFH Retirement Plan that covers certain Split Participants (“EFH Split Participants”); 

WHEREAS, the Separation Agreement by and between TXU Corp., a Texas corporation and Oncor Holdings dated October 10, 2007 set forth
certain provisions regarding the shared funding of pension benefits under the EFH Retirement Plan for the EFH Split Participants (such provisions are hereinafter collectively referred to as the “Funding Agreement”); 

WHEREAS, RTCEH shall for all purposes be the sponsor of the EFH Retirement Plan and RTCEH or its designee shall be plan administrator for the

 WHEREAS, the Parties desire and agree to continue to share the costs of funding of the EFH Retirement Plan as
described in this Schedule II; and NOW, THEREFORE, the Parties hereby agree as follows: 
  

	1.	 Aon Calculation Method. The Parties acknowledge and agree to continue to utilize the methods
of allocating liabilities, costs and expenses associated with the EFH Retirement Plan that are in effect on the date hereof, including (i) the method of allocating any amount that may be required to be contributed to any trust established for
the purpose of funding benefits under the EFH Retirement Plan, and (ii) the method for allocating between the Parties pension liabilities, costs and expenses under the EFH Retirement Plan (which method is described in the direct 2008 rate case
testimony filed with the Public Utilities Commission of Texas by Don Shipman, and more specifically described in the letter from Aon Hewitt to EFH dated November 13, 2012, addressing pension benefits, which is attached hereto as Exhibit II-A
(together with any mutually-agreed upon updates to said allocations, the “Aon Calculation Method”)). The Parties agree that the Aon Calculation Method is fair, appropriate and non-arbitrary, and that, pursuant to such method, each
Party will bear its fair share of such liabilities, costs and expenses. The term “Allocable Liabilities” shall mean, with respect to each Party, the projected benefit obligations allocated to such Party by the enrolled actuary for the EFH
Retirement Plan in accordance with the Aon Calculation Method. The Parties further agree that Allocable Liabilities shall be calculated by taking into account, if applicable, (i) any plan termination liability; (ii) any premiums payable to
the Pension Benefit Guaranty Corporation (the “PBGC”); (iii) the cost of obtaining annuities; and (iv) any other costs or expenses under the EFH Retirement Plan. The term “Allocable Assets” shall mean, with respect to
each Party, the fair value of the plan assets allocated to such Party by the enrolled actuary for the EFH Retirement Plan in accordance with the Aon Calculation Method. For avoidance of doubt, the Parties acknowledge that the Aon Calculation Method
utilizes Generally Accepted Accounting Principles (“GAAP”) to calculate Allocable Liabilities and Allocable Assets for an ongoing plan and a plan undergoing a “standard” plan termination as defined in ERISA § 4041(b), and
that the Aon Calculation Method utilizes the actuarial assumptions outlined in 29 

  
 13 

	 	
C.F.R. § 4044 in the event of a “distress” or “involuntary” plan termination as defined in ERISA § 4041(c) or 4042. RTCEH shall not alter or otherwise change the Aon
Calculation Method without the prior written agreement of Oncor other than as otherwise required by law. RTCEH as sponsor of the EFH Retirement Plan may amend the EFH Retirement Plan at any time, as required by federal laws, in order to ensure that
the EFH Retirement Plan maintains its qualified plan status and is in compliance with the requirements of any applicable collective bargaining agreement, ERISA, the Code and other applicable laws. Except as set forth in the immediately preceding
sentence, RTCEH further agrees it will not amend, modify or terminate the EFH Retirement Plan during the Transition Period without the consent of Oncor, which consent will not be unreasonably withheld and will not, without the consent of Oncor,
which will not be unreasonably withheld, amend, modify or terminate the EFH Retirement Plan at any time thereafter if such amendment, modification or termination reflects a material increase in the accrued benefit provided to any Split Participant
and that would result in a material increase in Oncor’s Allocable Liabilities with respect to the EFH Retirement Plan. 

  

	2.	Ongoing Reimbursement by Oncor to RTCEH in Respect of EFH Retirement Plan. 

  

	 	a.	Prior to the start of each plan year commencing after the year of the Separation and Transfer, the actuary for the EFH Retirement Plan will send a statement to Oncor and RTCEH identifying each Party’s share of the
required minimum contributions (determined in accordance with Code Section 412 and ERISA Section 302) (each such contribution a “Minimum Contribution,” and collectively, the “Minimum Contributions”) with respect to the
EFH Retirement Plan for such plan year and the due dates for the same, together with supporting documentation showing the calculation of such Minimum Contributions. Each Party’s share of each Minimum Contribution shall be calculated by
multiplying the amount of such Minimum Contribution by the percentage determined by dividing (i) such Party’s “Allocable Share of Unfunded Benefit Liabilities” (as defined below) by (ii) the sum of (A) such Party’s
Allocable Share of Unfunded Benefit Liabilities plus (B) the other Party’s Allocable Share of Unfunded Benefit Liabilities (each such Party’s portion of the Minimum Contribution as so determined is hereafter referred to as such
Party’s “Allocable Share of Minimum Contribution”). In the event the sum of all of Oncor’s Allocable Share of Minimum Contributions for a plan year exceeds its Allocable Share of Unfunded Benefit Liabilities for such plan year,
Oncor’s total Allocable Share of Minimum Contributions for such plan year shall be reduced to equal its Allocable Share of Unfunded Benefit Liabilities for such plan year, and RTCEH shall be responsible for the difference. In the event the
Allocable Share of Unfunded Benefit Liabilities for both Oncor and RTCEH are both zero, but there is a scheduled minimum contribution for the year, all scheduled contributions will be allocated to RTCEH. 

 

	 	b.	If the actuary cannot provide an allocation prior to the first required contribution for a plan year, the Parties agree that the actuary may provide an allocation based on an estimate of the contribution and its
allocation (with any differences between the estimated allocation and the final allocation reflected in subsequent contributions after the final allocation is completed). 

  
 14 

	 	c.	For each plan year, the actuary for the EFH Retirement Plan will perform a true-up calculation of each Party’s Allocable Share of Unfunded Benefit Liabilities for such plan year and shall adjust each Party’s
Allocable Share of Minimum Contribution accordingly for the next plan year. 

  

	 	d.	RTCEH shall tender each Minimum Contribution (including, for the avoidance of doubt, Oncor’s Allocable Share of Minimum Contribution and RTCEH’s Allocable Share of Minimum Contribution) to the EFH Retirement
Plan trust no later than ten (10) days prior to its due date. Within ten (10) days of receipt by Oncor from RTCEH of written documentation evidencing RTCEH’s contribution to the trust established for the EFH Retirement Plan of the
total Minimum Contribution due (including, for the avoidance of doubt, Oncor’s Allocable Share of Minimum Contribution and RTCEH’s Allocable Share of Minimum Contribution), Oncor agrees to pay to RTCEH its Allocable Share of Minimum
Contribution. In the event RTCEH does not contribute all or a portion of a Minimum Contribution to the trust established for the EFH Retirement Plan by the due date of such Minimum Contribution, Oncor may tender the unpaid portion of its Allocable
Share of Minimum Contribution on behalf of RTCEH directly to the trust established for the EFH Retirement Plan. Notwithstanding any provision of this Schedule II to the contrary, the payment by Oncor of its funding obligation under this
Section 2 is conditioned on RTCEH making a corresponding contribution in respect of its Allocable Share of Minimum Contribution. Oncor’s payment to RTCEH pursuant to this Section 2 shall reimburse RTCEH for the amount RTCEH tendered
to the EFH Retirement Plan with respect to Oncor’s Allocable Share of Minimum Contribution. 

  

	 	e.	For purposes of this Schedule II, the term “Allocable Share of Unfunded Benefit Liabilities” with respect to each Party shall mean the positive difference (if any) between (i) the applicable Party’s
Allocable Liabilities minus (ii) the applicable Party’s Allocable Assets, as determined in accordance with Section 1 of this Schedule II on an ongoing basis. If a Party’s Allocable Assets exceeds such Party’s Allocable
Liabilities, the Party’s Allocable Share of Unfunded Benefit Liabilities shall be zero. In calculating a Party’s “Allocable Share of Unfunded Benefit Liabilities,” Allocable Assets and Allocable Liabilities shall be determined as
of the end of the year preceding the relevant contribution year. 

  

	 	f.	For the year in which the Separation and Transfer occurs, the Party’s agree to provide any required minimum funding contributions in accordance with a statement to be provided by the actuary following the effective
date of this Agreement. 

  

	3.	Specific Event Reimbursement by Oncor to RTCEH in Respect of EFH Retirement Plan. In the event that in any given plan year the enrolled actuary of the EFH Retirement Plan determines that any of the
benefit restrictions under Code Section 436 (“Benefit Restrictions”) may, in its reasonable discretion, apply to the EFH Retirement Plan, the enrolled actuary shall calculate the contribution amount owed by each Party to avoid the
Benefit Restrictions based on each Party’s Allocable Share of Unfunded Benefit Liabilities and shall advise the Parties of the timing of the required contributions; provided, however, that if a Party’s Allocable Share of Unfunded
Benefit Liabilities is zero, the other Party shall tender the entire contribution amount necessary to avoid the Benefit Restrictions. 

  
 15 

 Oncor shall, upon written request from RTCEH, which request shall include supporting
documentation showing the calculation of such contribution amount owed and evidence of RTCEH’s payment to the trust under the EFH Retirement Plan of such amount (the “Benefit Restriction Request”), timely tender to RTCEH its Allocable
Share of Unfunded Benefit Liabilities up to the maximum amount required to avoid Benefit Restrictions. For the avoidance of doubt, Oncor shall not remit payment to RTCEH in accordance with this Section 3 until RTCEH has contributed such amount
to the trust under the EFH Retirement Plan. Notwithstanding any provision of this Schedule II to the contrary, the payment by Oncor of its funding obligation under this Section 3 is conditioned on RTCEH making a corresponding contribution in
respect of its Allocable Share of Unfunded Benefit Liabilities unless RTCEH’s Allocable Share of Unfunded Benefit Liabilities is zero at the time such contribution is necessary. RTCEH shall timely tender its Allocable Share of Unfunded Benefit
Liabilities up to the maximum amount owed to avoid Benefit Restrictions as well as the amount of the Benefit Restriction Request to the EFH Retirement Plan trust. Oncor’s payment of the Benefit Restriction Request to RTCEH shall reimburse RTCEH
for the amount RTCEH tendered to the EFH Retirement Plan with respect to the Benefit Restriction Request. In the event that RTCEH fails to timely tender the amount of the Benefit Restriction Request to the EFH Retirement Plan trust, Oncor will
tender the amount of the Benefit Restriction Request on behalf of RTCEH directly to the EFH Retirement Plan trust. 
  

	4.	Plan Termination. In the event that RTCEH wishes to terminate the EFH Retirement Plan under a standard or distress termination, RTECH shall provide Oncor with notice of at least one hundred fifty
(150) days prior to the proposed termination date. In the event RTCEH receives written notice of the PBGC’s intent to initiate an involuntary termination of the EFH Retirement Plan, RTCEH shall promptly provide Oncor with such written
notice. In the case of a standard, distress, or involuntary plan termination, the EFH Retirement Plan enrolled actuary shall calculate the (i) plan termination liability and (ii) any other costs or expenses under the EFH Retirement Plan,
in accordance with the assumptions for terminating such plan and each Party shall pay its respective share of the plan termination liability by the date indicated by the enrolled actuary, which shall in each case be prior to the date(s) mandated by
ERISA. Notwithstanding any provision of this Schedule II to the contrary, in the event that Oncor has a funding obligation under this Section 4 as a result of a standard termination, the payment by Oncor of its funding obligations under this
Section 4 is conditioned on RTCEH making a corresponding contribution in respect of its share of such termination liabilities. Upon satisfaction of Oncor’s payment of such liability and other costs and expenses, Oncor shall have no further
obligation to RTCEH in respect of the EFH Retirement Plan other than as provided in this Agreement. 

  

	5.	Contributing Sponsor Status. Notwithstanding any other provision of this Agreement or Schedule II to the contrary, the Parties acknowledge and agree that Oncor’s obligation in respect of the
funding of the EFH Retirement Plan is solely a contractual obligation to RTCEH under this Agreement and that Oncor shall be liable under this Schedule II only for its Allocable Share of Unfunded Benefit Liabilities and shall not be liable for
RTCEH’s Allocable Share of Unfunded Benefit Liabilities under the EFH Retirement Plan. It is the intent of the Parties that Oncor is not and will not become a “contributing sponsor” of the EFH Retirement Plan as such term is defined
in ERISA Section 4001(a)(13), and nothing contained in this Schedule II or otherwise in this Agreement shall be construed otherwise. 

  
 16 

	6.	Plan Administrative Expenses. Except as otherwise provided in Exhibit II-B, the Parties agree that Permissible Expenses (as defined below) shall be charged against each party’s Allocable Assets
in proportion to each party’s Allocable Assets compared to the total assets under the EFH Retirement Plan as of the date designated by the plan administrator. The term “Permissible Expenses” includes those expenses properly payable
from the plan assets of the EFH Retirement Plan in accordance with ERISA. Expenses that are not properly payable from plan assets shall be allocated in accordance with historical practice. 

 

	7.	Dispute Resolution. Notwithstanding any provision of this Agreement to the contrary, Oncor may engage its own enrolled actuary to calculate its Allocable Liabilities, Allocable Assets, Allocable Share of
Unfunded Benefit Liabilities, and any and all payments to be made by Oncor in accordance with this Schedule II. If the Parties’ enrolled actuaries do not agree on any such calculations, the Parties agree that they shall cause each enrolled
actuary to prepare and deliver to the other a statement setting forth the enrolled actuary’s calculation and methodologies. The Parties agree to negotiate in good faith for 60 days following receipt of such statements in order to come to an
agreement as to such calculations. If, at the end of such 60 day period, the enrolled actuaries and the Parties have not resolved such disputes, the two enrolled actuaries shall select a third enrolled actuary, and such third enrolled actuary shall
determine which of the calculation and methodologies prepared by the two prior enrolled actuaries is correct. Such new enrolled actuary’s determination shall be set forth in a written statement delivered to the Parties and the determination
shall be final, binding and non-appealable. All fees and expenses of such third enrolled actuary shall be borne 50% by Oncor and 50% by RTCEH. 

  

	8.	Reservation of Rights. Nothing in this Schedule II shall be deemed to constitute a provision of, or an amendment to the EFH Retirement Plan or any other benefit plan maintained by either Oncor or
RTCEH, nor shall this Schedule II be deemed to limit, in any way, the authority of either Oncor or RTCEH to amend or terminate their respective benefit plans from time to time in accordance with the terms of such plans except as otherwise provided
in Section 1 hereof. 

  

	9.	No Third Party Beneficiary Rights. Nothing in this Schedule II shall create any third party beneficiary rights for any individual, including without limitation, any EFH Split
Participant or his/her beneficiary, nor shall this Schedule II be deemed to provide any EFH Split Participant or beneficiary, or any other individual, with any right to continued coverage under the EFH Retirement Plan or any other plan of Oncor or
RTCEH. This Schedule II relates solely to the EFH Retirement Plan and does not affect RTCEH’s obligation to any participant or beneficiary who is not an EFH Split Participant. 

  
 17 

	10.	Termination. This Schedule II will automatically terminate in the event that (a) the EFH Retirement Plan is terminated; or (b) benefits under the EFH Retirement Plan are no longer payable
to EFH Split Participants. 

  

	11.	Representation on EFH Retirement Plan Investment Committee. During the term of the obligations under this Schedule II the investments of the trust for the EFH Retirement Plan shall be governed by a
committee (the “Investment Committee”), and Oncor shall have the right to have three (3) voting members named by Oncor when the Investment Committee has seven (7) voting members. 

  
 18 

 SCHEDULE III 

LIFE INSURANCE 

WHEREAS, certain retirees of Oncor, RTCEH and their predecessors and affiliates may be eligible for life insurance subsidies from both Oncor
and RTCEH; and WHEREAS, the Parties have agreed to address the provision of life insurance benefits to such retirees in accordance with this Schedule III. 

NOW, THEREFORE, the Parties hereby agree as follows: 

1. On [•], RTCEH will pay Oncor $[negotiated amount based on actuarial calculation] for full payment of the life insurance premiums for
Split Participants in proportion to their non-regulated service. 
 2. Oncor will assume all of EFH’s obligations and liabilities with
respect to life insurance benefits being provided to the Split Participants listed in the attached Exhibit III-A. 
 3. Oncor will
continue providing the same level of life insurance benefits currently provided. 
 4. If Oncor terminates the life insurance benefits being
provided to the Split Participants listed on Exhibit III-A prior to the date that all amounts paid in Section 1 of this Schedule III have been used by Oncor to pay or fund premiums for such life insurance benefits, Oncor shall pay to
RTCEH the net amount paid under Section 1 less the actual out-of-pocket amounts used to pay life insurance premiums for such participants through the date on which such benefits are terminated.

and file (or cause to be prepared and filed) each Tax Return required to be filed by a Reorganized TCEH Entity after the Distribution Date and shall pay, or cause be paid, all Taxes shown to be due and payable on such Tax Return; provided, that the

extent not in conflict with this Agreement, the applicable Intended Tax Treatment and the Tax Materials) commercial practice. All Tax Returns shall be filed on a timely basis (taking into account applicable extensions) by the Party responsible for
filing such Tax Returns under this Agreement. 
 (b) Right to Review Certain Returns Prepared by EFH. In the case of any
Tax Return described in Section 2.01(a), (i) the portion (if any) of such Tax Return that relates to Reorganized TCEH Taxes or would reasonably be expected to adversely affect the Tax position of any Reorganized TCEH Entity shall

Section 2.01(b) that relates to EFH Taxes or that would reasonably be expected to adversely affect the Tax position of any Reorganized EFH Entity, (i) such Tax Return shall (to the extent permitted by law) be prepared in a manner
described in Section 2.02(a) and (ii) Reorganized TCEH shall provide a draft of such Tax Return to EFH for its review and comment at least thirty (30) days prior to the Due Date for such Tax Return, or in the case of any such
Tax Return filed on a monthly basis or property Tax Return, ten (10) days. Reorganized TCEH shall consider in good faith any reasonable comment received from EFH at least three (3) days prior to the Due Date for such Tax Return. In the
event that neither the Intended Tax Treatment, the Tax Materials nor commercial practice are applicable to a particular item or matter, Reorganized TCEH shall determine the reporting of such item or matter in good faith in consultation with EFH. The
Parties shall negotiate in good faith to resolve all disputed issues. Any disputes that the Parties are unable to resolve shall be resolved by the Accounting Firm pursuant to Section 9.02. In the event that any dispute is not resolved
(whether pursuant to good faith negotiations among the Parties or by the Accounting Firm) prior to the Due Date for the filing of any Tax Return, such Tax Return shall be timely filed as prepared by Reorganized TCEH and such Tax Return shall be
amended as necessary to reflect the resolution of such dispute in a manner consistent with such resolution. For the avoidance of doubt, each Reorganized TCEH Entity shall be jointly and severally responsible for any interest, penalties or additions
to Tax resulting from the late filing of any Tax Return Reorganized TCEH is required to file under Section 2.01(b) except to the extent that such late filing is primarily caused by the failure of any Reorganized EFH Entity to provide
relevant information necessary for the preparation and filing of such Tax Return. 
 (d) Tax Reporting. Unless otherwise
required by law, if the Spin-Off occurs, EFH and Reorganized TCEH, as applicable, shall file the appropriate information and statements, as required by Treasury Regulations Sections 1.355-5(a) and 1.368-3, with the IRS, and shall retain the
appropriate information relating to the Contribution, the Reorganized TCEH Conversion and the Distribution as described in Treasury Regulations Sections 1.355-5(d) and 1.368-3(d). 

(e) Amendments. Any amendment of any Tax Return described in Section 2.01 of any Reorganized TCEH Entity shall be subject to
the same procedures required for the preparation of such type of Tax Return of such Reorganized TCEH Entity pursuant to this Section 2.02. Any amendment of any Tax Return described in Section 2.01 of any Reorganized EFH
Entity shall be subject to the same procedures required for the preparation of such type of Tax Return of such Reorganized EFH Entity pursuant to this Section 2.02. 

  
 14 

 Section 2.03 Straddle Period Tax Allocation. To the extent permitted by
law, EFH and Reorganized TCEH shall elect, or cause an election to be made, to close the taxable year of each Reorganized TCEH Entity as of the close of the Distribution Date. In the case of any Straddle Period, the amount of any Income Taxes
attributable to the portion of the Straddle Period ending on, or beginning after, the Distribution Date shall be made by means of a closing of the books and records of such Reorganized TCEH Entity as of the close of the Distribution Date; provided,
that in the case of Non-Income Taxes that are periodic Taxes (e.g., property Taxes) and exemptions, allowances, and deductions that are calculated on an annual basis (such as depreciation deductions), such Taxes, exemptions, allowances, and
deductions shall be allocated between the portion of the Straddle Period ending at the end of the Distribution Date and the portion beginning after the Distribution Date based upon the ratio of (a) the number of days in the relevant portion of
the Straddle Period to (b) the number of days in the entire Straddle Period; provided, however, that in allocating any such exemptions, allowances, or deductions (or increase in such amounts) between the two periods that comprise a Straddle
Period, any such items that relate to an asset or property that was sold, acquired or improved during the Straddle Period shall be allocated on a daily basis solely among the days in the Straddle Period during which such asset was owned or such
improvement existed; provided, further, that Taxes that are properly allocable (based on, among other relevant factors, factors set forth in Treasury Regulations Section 1.1502-76(b)(1)(ii)(B)) to a portion of the Distribution Date following
the Distribution, shall be allocable to the portion of the Straddle Period beginning after the Distribution Date. 

Section 2.04 Allocation of Taxes. 

(a) Income Taxes. Income Taxes (other than Income Taxes allocated pursuant to Section 2.04(b), Section 2.04(d),
and Section 2.05) shall be allocated in an appropriate manner, consistent with commercial practice, and as follows: 

(i) In the case of U.S. federal regular Income Taxes, in proportion to the separate taxable income (calculated in a manner
consistent with Treasury Regulations Section 1.1552-1(a)(1) and determined without regard to any items the Income Taxes for which are allocated pursuant to Section 2.04(b), Section 2.04(d), and Section 2.05)
attributable to (x) any Reorganized EFH Entity (treated as if all of the assets and liabilities of such entities were combined into a single corporation) (such single corporation, the “EFH Consolidated Corporation”), including
any business or assets retained by such entities following the Distribution Date, on the one hand, and (y) any Reorganized TCEH Entity (treated as if all of the assets and liabilities of such entities were combined into a single corporation)
(such single corporation, the “Reorganized TCEH Consolidated Corporation”), including any business or assets contributed to or otherwise held by such entities following the Distribution Date, on the other hand. 

(ii) In the case of Texas Margin Tax, the methodology specified in Section 2.04(a)(i) shall be applied, and Texas
Margin Tax shall be allocated, based on the separate taxable margins of the EFH Consolidated Corporation, on the one hand, and the Reorganized TCEH Consolidated Corporation, on the other hand. 

  
 15 

 (b) Alternative Minimum Taxes. Alternative minimum Taxes (other than alternative
minimum Taxes allocated pursuant to Section 2.04(d) and Section 2.05) shall be allocated in proportion to the respective separate amounts of alternative minimum tax of the EFH Consolidated Corporation, on the one hand, and
the Reorganized TCEH Consolidated Corporation, on the other hand. 
 (c) Non-Income Taxes. Except as provided in
Section 2.04(d)(i), Non-Income Taxes shall be allocated between the EFH Parties, on the one hand, and Reorganized TCEH, on the other hand, based on the applicable items attributable to or arising from any business retained by any
Reorganized EFH Entity, on the one hand, and any business contributed to (or otherwise held on the Effective Date by) any Reorganized TCEH Entity, on the other hand, that contribute to such Taxes (e.g., sales Taxes and value added Taxes shall be
allocated to the EFH Parties to the extent arising from taxable sales made by any business retained by any Reorganized EFH Entity). In the event that any Non-Income Tax is not attributable to (and does not arise from) any items relating to any
business (e.g., capital Taxes imposed based on the authorized stock), such Non-Income Taxes shall be allocated between the EFH Parties, on the one hand, and Reorganized TCEH, on the other hand, in proportion to the net taxable income of any business
retained by any Reorganized EFH Entity, on the one hand, and any business contributed to (or otherwise held on the Effective Date by) any Reorganized TCEH Entity, on the other hand. 

(d) Other Taxes. 

(i) Transfer Taxes, if any, related to or arising as a result of the Spin-Off or the Taxable Separation shall be allocated one
hundred percent (100%) to the TCEH Parties. Transfer Taxes, if any, arising as a result of restructuring of the EFH Parties or a direct or indirect acquisition of an interest in Oncor shall be allocated one hundred percent (100%) to the
EFH Parties. Other Transfer Taxes, if any, will be allocated to the EFH Parties if they constitute items attributable to the EFH Consolidated Corporation and to Reorganized TCEH if they constitute items attributable to the Reorganized TCEH
Consolidated Corporation. 
 (ii) If the Spin-Off occurs, Income Taxes attributable to a Tax-Free Transaction Failure shall
be allocated as set forth in Section 2.05. 
 (iii) If the Spin-Off occurs, an amount (but not less than zero)
equal to fifty percent (50%) of U.S. federal alternative minimum tax liability (including any adjustments pursuant to a Final Determination), if any, that results from the limitation on the utilization of the net operating losses to offset gain
recognized from the Spin-Off Preferred Stock Sale under Section 56(d)(1)(A) of the Code shall be allocated to the EFH Parties. 

(iv) If the Spin-Off occurs, the Additional Spin-Off Preferred Stock Sale Tax shall be allocated to Reorganized TCEH. 

  
 16 

 (v) If the Spin-Off occurs and there has been no Tax-Free Transaction Failure,
any discharge of indebtedness income or gain under Section 1001 of the Code arising from any discharge of indebtedness shall be allocated to the EFH Parties. 

(e) Allocation of Tax Attributes. Tax Attributes, if any, remaining after the Distribution (other than net operating losses)
shall be allocated in accordance with the Private Letter Ruling or, if not addressed in the Private Letter Ruling, between the Reorganized EFH Entities, on the one hand, and the Reorganized TCEH Entities, on the other hand, in
accordance with the Code and Treasury Regulations, including Treasury Regulations Section 1.1502-76 (and any applicable state, local and foreign Laws) and, with respect to earnings and profits, as initially requested in the IRS Submissions. The
allocation of such Tax Attributes shall be determined by treating the Reorganized TCEH Entities as one consolidated group and the Reorganized EFH Entities as a separate and distinct consolidated group. Any disputes shall be resolved by the
Accounting Firm in accordance with Section 9.02. The EFH Parties and Reorganized TCEH hereby agree to compute all Taxes consistently with the determination of the allocation of Tax Attributes pursuant to this Section 2.04(e)
unless otherwise required by a Final Determination. For the avoidance of doubt, in the event the Taxable Separation occurs, no Tax Attributes (other than tax basis) shall be allocated to the Reorganized TCEH Entities unless otherwise required by a
Final Determination. 
 Section 2.05 Allocation of Separation-Related Taxes. If the Spin-Off occurs: 

(a) No-Fault. Income Taxes attributable to a Tax-Free Transaction Failure, to the extent not allocated pursuant to Sections
2.05(b), (c) or (d), shall be allocated to the EFH Parties. 
 (b) EFH Breach. Income Taxes principally
attributable to a Tax-Free Transaction Failure as a result of an EFH Breach shall be allocated to the EFH Parties. 
 (c)
Reorganized TCEH Breach. Incomes Taxes principally attributable to a Tax-Free Transaction Failure as a result of Reorganized TCEH Breach shall be allocated to the Reorganized TCEH Entities. 

(d) Certain Actions by TCEH Creditors and Holders of Reorganized TCEH Stock and Securities. Income Taxes principally attributable
to a Tax-Free Transaction Failure resulting from any action taken by the TCEH Creditors or by holders of stock or securities in Reorganized TCEH with respect to their interests that (i) causes the Distribution not to satisfy the continuity of
interest requirement set forth in Treasury Regulations Section 1.368-1(e) or 1.355-2(c)(1), (ii) results in the imposition of any Income Taxes under Section 355(d) or Section 355(e) of the Code with respect to the Distribution,
or (iii) results in the Distribution failing to satisfy the device test set forth in Treasury Regulations Section 1.355-2(d), shall be allocated to Reorganized TCEH. 

Section 2.06 Audits/Redeterminations. Any redetermined Taxes or Tax Attributes resulting from an audit shall be allocated between
the EFH Parties, on the one hand, and Reorganized TCEH, on the other hand, in the same manner as they would have been allocated had the redetermined amounts been known at the time the original Tax liability was computed. 

  
 17 

 Section 2.07 Expenses. Except as provided in Section 9.02 in respect of
the Accounting Firm, each Party shall bear its own expenses incurred in connection with this Article II. 
 Section 2.08
Timing of Payments. Any reimbursement of Taxes under Section 2.01 shall be made upon the later of (a) two (2) business days before the Due Date of such payment of such Taxes and (b) ten (10) business days after the
party required to make such reimbursement has received notice from the party entitled to such reimbursement. For the avoidance of doubt, a party may provide notice of reimbursement of Taxes prior to the time such Taxes were paid, and such notice may
represent a reasonable estimate (provided, that the amount of reimbursement shall be based on the actual Tax liability and not on such reasonable estimate). 

ARTICLE III 
 Indemnification

 Section 3.01 Indemnification by the Reorganized EFH Entities. The Reorganized EFH Entities, on a joint and several basis,
shall pay (or cause to be paid), and shall indemnify and hold each Reorganized TCEH Entity harmless from and against, without duplication, all EFH Taxes and all losses or damages arising out of, resulting from or relating to any breach by any
Reorganized EFH Entity of any EFH representation, warranty, covenant or agreement in this Agreement (including, in the case of a Tax-Free Transaction Failure pursuant to Section 2.05(b), any reduced depreciation, amortization or similar
deduction or any reduced loss or increased gain, in each case resulting from a reduction in the income tax basis of any asset of any Reorganized TCEH Entity resulting from such Tax-Free Transaction Failure pursuant to Section 2.05(b),
such loss or damage determined (a) without regard to any tax receivable agreement or similar arrangement with respect to any Reorganized TCEH Entity and (b) taking into account any Final Determinations relating to the income tax basis of
any asset immediately after the Spin-Off); provided, that for the avoidance of doubt, for so long as the Oncor Entities have not executed a joinder to this Agreement pursuant to Section 9.19, the Oncor Entities shall have no obligation
under this Section 3.01. 
 Section 3.02 Indemnification by the Reorganized TCEH Entities. The Reorganized TCEH Entities, on a
joint and several basis, shall pay (or cause to be paid), and shall indemnify and hold each Reorganized EFH Entity harmless from and against, without duplication, all Reorganized TCEH Taxes and all losses or damages arising out of, resulting from or
relating to any breach by any Reorganized TCEH Entity of any Reorganized TCEH representation, warranty, covenant or agreement in this Agreement. 

Section 3.03 Characterization of and Adjustments to Payments. 

(a) In the absence of a Final Determination to the contrary, for all Tax purposes, EFH and Reorganized TCEH shall treat or cause to be treated
any payment required by this Agreement (other than any payment treated for Tax purposes as interest) as either a contribution by EFH to Reorganized TCEH or a distribution by Reorganized TCEH to EFH, as the case may be, occurring immediately prior to
the Distribution. 

  
 18 

 (b) Any indemnity payment pursuant to this Agreement shall be (A) increased to include
(i) all reasonable accounting, legal, and other professional fees and court costs and damages incurred by the Indemnified Party in connection with such indemnity payment and (ii) any Tax Cost to such Indemnified Party or its Affiliates
resulting from the receipt of (or entitlement to) such indemnity payment and (B) decreased to account for any Tax Benefit that the Indemnified Party or its Affiliates actually realizes by way of a Refund or a decrease in Taxes reported on a
filed Tax Return (in or with respect to a taxable year that ends on or before December 31, 2021) in connection with the incurrence or the payment by the Indemnified Party of such fees or costs or indemnifiable amounts determined using a
“with and without” methodology (treating any deductions attributable to such fees or costs or indemnifiable amounts as the last items claimed for any taxable year, including after the utilization of any available net operating loss
carryovers). In the event that any Tax Cost or Tax Benefit is not actually realized at the time of the indemnity payment by the Indemnifying Party to the Indemnified Party, the payment related to such Tax Cost or Tax Benefit shall be paid at the
time the Tax Cost or Tax Benefit is actually realized. 
 Section 3.04 Timing of Indemnification Payments. Indemnification
payments in respect of any liabilities for which an Indemnified Party is entitled to indemnification pursuant to this Article III shall be paid by the Indemnifying Party to the Indemnified Party within ten (10) days after written
notification thereof by the Indemnified Party, including reasonably satisfactory documentation setting forth the basis for, and calculation of, the amount of such indemnification payment. If an indemnification obligation is attributable to a Tax
which the Indemnified Party pays, but for which no Final Determination has been made (such as a payment in response to an asserted adjustment in audit, which adjustment remains subject to further challenge), then the Indemnifying Party shall pay
such amounts to the Indemnified Party within ten (10) days after written notification thereof by the Indemnified Party, including reasonably satisfactory documentation setting forth the basis for, and calculation of, the amount of such
indemnification payment, provided, that, in the event that such amounts are returned or refunded to Indemnified Party, the Indemnified Party shall pay such amounts to the Indemnifying Party within (10) days of receipt thereof plus interest at a
rate equal to the rate provided in Section 9.04. 
 Section 3.05 Exclusive Remedy. Anything to the contrary in this
Agreement notwithstanding, but in all events subject to Article VIII, the EFH Parties and the Reorganized TCEH Entities hereby agree that the sole and exclusive monetary remedy of a party for any breach or inaccuracy of any
representation, warranty, covenant or agreement contained in Section 6.01 shall be the indemnification rights set forth in this Article III. 

Section 3.06 No Duplicative Payment. Notwithstanding anything to the contrary in this Agreement, it is intended that the
provisions of this Agreement will not result in a duplicative payment of any amount required to be paid under any other Transaction Agreement, and this Agreement shall be construed accordingly. 

  
 19 

 ARTICLE IV 

Refunds, Timing Differences, and Tax Attributes 

Section 4.01 Refunds. 

(a) Except as provided in Section 4.02, EFH shall be entitled to all Refunds of Taxes for which a Reorganized EFH Entity or its
Affiliates is responsible pursuant to Article III, and Reorganized TCEH shall be entitled to all Refunds of Taxes for which Reorganized TCEH or its Affiliates is responsible pursuant to Article III. A Party receiving a Refund to which
the other Party is entitled pursuant to this Agreement shall pay the amount to which such other Party is entitled (less any Tax or other reasonable out-of-pocket costs incurred by the first Party in receiving such Refund within ten (10) days
after the receipt of the Refund. 
 (b) To the extent that the amount of any Refund under this Section 4.01 is later reduced by a
Taxing Authority or in a Tax Proceeding, such reduction shall be allocated to the Party to which such Refund was allocated pursuant to this Section 4.01 and an appropriate adjusting payment shall be made. 

Section 4.02 Timing Differences. If pursuant to a Final Determination any Tax Attribute (including those allocated pursuant to
Section 2.04(e)) is made allowable to a Reorganized TCEH Entity as a result of an adjustment to any Taxes for which an EFH Party is responsible hereunder (other than Taxes attributable to a Tax-Free Transaction Failure described in
Section 2.05(a) or Section 2.05(b)) and such Tax Attribute would not have arisen or been allowable but for such adjustment, or if pursuant to a Final Determination any Tax Attribute is made allowable to a Reorganized EFH
Entity as a result of an adjustment to any Taxes for which Reorganized TCEH is responsible hereunder (other than Taxes attributable to a Tax-Free Transaction Failure described in Section 2.05(c) or 2.05(d)) and such Tax Attribute would
not have arisen or been allowable but for such adjustment, the Reorganized TCEH Entities (on a joint and several basis) or the Reorganized EFH Entities (on a joint and several basis), as the case may be, shall make a payment to either EFH or
Reorganized TCEH, as appropriate, within thirty (30) days after such Party (or its Affiliates) actually realizes a Tax benefit by way of a Refund or a decrease in Taxes reported on a filed Tax Return (in or with respect to a taxable year that
ends on or before December 31, 2021) that is attributable to such Tax Attribute, determined using a “with and without” methodology (treating any deductions or amortization attributable to such Tax Attributes as the last items claimed
for any taxable year, including after the utilization of any available net operating loss carryovers); provided, that no payment shall be made under this Section unless Reorganized TCEH or EFH, as the case may be, has previously paid the Tax
adjustment or indemnified the other Party for such Tax adjustment. In the event of any overlap between Section 3.03 and this Section 4.02, this Section 4.02 shall apply and Section 3.03 shall not
apply. 
 ARTICLE V 
 Tax
Proceedings 
 Section 5.01 Notification of Tax Proceedings. Within ten (10) days after an Indemnified Party becomes
aware of the commencement of a Tax Proceeding that may give rise to an indemnity payment pursuant to Article III, such Indemnified Party shall notify the Indemnifying Party in writing of such Tax Proceeding, and thereafter shall promptly
forward or make available to the Indemnifying Party copies of notices and communications relating to such Tax Proceeding. The failure of the Indemnified Party to notify the Indemnifying Party in writing of the commencement of any such Tax Proceeding
within such ten (10) day period or promptly forward any further notices or communications shall not relieve the Indemnifying Party of any obligation which it may have to the Indemnified Party under this Agreement except to the extent (and only
to the extent) that the Indemnifying Party is actually materially prejudiced by such failure. 

  
 20 

 Section 5.02 Tax Proceeding Procedures. 

(a) EFH. EFH shall be entitled to contest, compromise, and settle any adjustment that is proposed, asserted or assessed pursuant to any
Tax Proceeding with respect to any Tax Return it is responsible for preparing pursuant to Article II; provided, that to the extent that such Tax Proceeding relates to Reorganized TCEH Taxes or would reasonably be expected to materially
adversely affect the Tax position of any Reorganized TCEH Entity for any Post-Distribution Period, EFH shall (i) keep Reorganized TCEH informed in a timely manner of the material actions proposed to be taken by EFH with respect to such Tax
Proceeding, (ii) permit Reorganized TCEH at its own expense to participate in the aspects of such Tax Proceeding that relate to Reorganized TCEH Taxes, and (iii) not settle any aspect of such Tax Proceeding that relates to Reorganized TCEH
Taxes without the prior written consent of Reorganized TCEH, which shall not be unreasonably withheld, delayed or conditioned. Notwithstanding the foregoing, Reorganized TCEH shall have the right to jointly control any Tax Proceeding that relates
primarily to Taxes for which Reorganized TCEH has an indemnification obligation pursuant to Section 3.02. 
 (b) Reorganized
TCEH. Except as otherwise provided in Section 5.02(a), Reorganized TCEH shall be entitled to contest, compromise, and settle any adjustment that is proposed, asserted or assessed pursuant to any Tax Proceeding with respect to any Tax
Return it is responsible for preparing pursuant to Article II; provided, that to the extent that such Tax Proceeding relates to EFH Taxes or would reasonably be expected to materially adversely affect the Tax position of any Reorganized EFH
Entity, Reorganized TCEH shall (i) keep EFH informed in a timely manner of the material actions proposed to be taken by Reorganized TCEH with respect to such Tax Proceeding, (ii) permit EFH at its own expense to participate in the aspects
of such Tax Proceeding that relate to EFH Taxes, and (iii) not settle any aspect of such Tax Proceeding that relates to EFH Taxes without the prior written consent of EFH, which shall not be unreasonably withheld, delayed or conditioned.
Notwithstanding the foregoing, the EFH Parties shall have the right to jointly control any Tax Proceeding that relates primarily to Taxes for which EFH Parties have an indemnification obligation pursuant to Section 3.01. 

Section 5.03 Consistency. The Parties shall (and shall cause each of their respective Subsidiaries to) take the position on
all Tax Returns and in all Tax Proceedings (including in supplemental ruling request submissions to the IRS), unless otherwise required by a Final Determination, that (a) the transactions contemplated by the Plan qualify for the Spin-Off
Intended Tax Treatment (in the case of the Spin-Off) or the Taxable Separation Intended Tax Treatment (in the case of the Taxable Separation), and (b) the fair market value of each Stepped-Up TCEH Asset on the Distribution Date is equal to the
value of such asset that has been reasonably agreed to by the TCEH Supporting First Lien Creditors and the Debtors. 

  
 21 

 ARTICLE VI 

Spin-Off Intended Tax Treatment 

Section 6.01 Restrictions Relating to the Distribution. 

(a) General. If the Spin-Off occurs, following the Distribution, (i) EFH will not (and will cause each other Reorganized EFH

inconsistent with the facts presented and the representations made prior to the Distribution Date with respect to any Tax Materials submitted specifically with respect to obtaining a ruling [or opinion] with respect to the treatment of the
cancellation of the TCEH debt, and solely to the extent such action or representation specifically relates to, and is relevant to, any ruling obtained with respect to the treatment of the cancellation of the TCEH debt and (z) Reorganized TCEH
will not (and will cause each other Reorganized TCEH Entity and its Affiliates not to) take any action (or refrain from taking any action) which is inconsistent with such facts presented and the representations made prior to the Distribution Date

(i) continue the active conduct of each trade or business (for purposes of Section 355(b) of the Code and the Treasury
Regulations thereunder) (A) that it was engaged in immediately prior to the Distribution (taking into account Section 355(b)(3) of the Code), (B) that was being relied upon for purposes of satisfying the requirements of

(vi) not directly or indirectly acquire any of the Preferred Stock. 

(c) Certain Exceptions. Notwithstanding the restrictions imposed by Section 6.01(b), during the Restriction Period, the EFH
Parties and Reorganized TCEH may proceed with any of the actions or transactions described therein, if: 
 (i) such action or
transaction is described in (or is otherwise consistent with) the facts in the Private Letter Ruling;

 (v) such action by the EFH Parties and/or their Affiliates is approved in writing by Reorganized TCEH and such action by

 (d) EFH Party Covenants.
Each EFH Party shall not and shall cause each of its Subsidiaries not to: 

  
 23 

 (i) propose or support an EFH Plan or any other transaction (A) pursuant to
which EFH or EFIH, directly or indirectly, transfers their indirect economic interest in Oncor, the consummation of which would breach this Agreement or (B) which would reasonably be expected to create a material risk of (x) a Tax-Free
Transaction Failure or (y) a breach by the EFH Parties of any term or condition of this Agreement; and 
 (ii) take any
action without the consent of Reorganized TCEH outside the ordinary course of business that, in the reasonable determination of Reorganized TCEH, would give rise to $250 million or more of net taxable income recognized by the EFH Group (when
combined with any other net taxable income of the EFH Group, but excluding, for the avoidance of doubt, (x) the net taxable income arising in connection with the transactions constituting the Spin-Off and (y) any Agreed Tax Attributes) in
the same taxable year as the TCEH Effective Date; provided, however, that in the event an EFH Party seeks to take any action outside the ordinary course of business that, in the reasonable determination of Reorganized TCEH, would give rise to $250
million or more of net taxable income recognized by the EFH Group (when combined with any other net taxable income of the EFH Group, but excluding, for the avoidance of doubt, (x) the net taxable income arising in connection with the Spin-Off
Preferred Stock Sale and (y) any Agreed Tax Attributes) in the same taxable year as the TCEH Effective Date, Reorganized TCEH shall consent to such transaction if it concludes in its sole discretion that such transaction will not give rise to a
material risk of nonpayment of an amount owed (whether due to such transaction or otherwise) under this Agreement or to an applicable taxing authority. 

(e) Additional Covenants. 

(i) If the Plan is consummated without receiving the Private Letter Ruling (or any Fundamental Ruling), then EFH shall continue
to pursue the Private Letter Ruling (or a supplemental Private Letter Ruling, if applicable) until a determination is made by EFH and Reorganized TCEH (each making their determination under a reasonable exercise of discretion) that the Private
Letter Ruling or supplemental Private Letter Ruling cannot be obtained. Parent and Reorganized TCEH shall have the right to participate in any submissions related to the Private Letter Ruling, including by (i) commenting on written submissions,
(ii) having participation in in-person conferences, (iii) having participation in scheduled, substantive telephone conferences with the IRS, and (iv) being updated promptly regarding any unscheduled communications with the IRS or any
other communications with respect to which Parent or Reorganized TCEH does not participate; provided, however, that Parent and Reorganized TCEH shall work in good faith with counsel for EFH to determine the appropriate level of participation by any
other persons in any particular meeting or conference. 
 (ii) If the Plan is consummated after the receipt of the Private
Letter Ruling, supplemental submissions with respect to the Private Letter Ruling shall be made to reflect any material developments with respect to the EFH Plan to the extent such developments may implicate the Spin-Off Intended Tax Treatment.
Parent and Reorganized TCEH shall have the right to participate in such supplemental submissions, including by (A) commenting on written submissions, (B) having participation in in-person conferences,
(C)

  
 24 

 
having participation in scheduled, substantive telephone conferences with the IRS, and (D) being updated promptly regarding any unscheduled communications with the IRS or any other
communications with respect to which Parent or Reorganized TCEH does not participate; provided, however, that Parent and Reorganized TCEH shall work in good faith with counsel for the EFH Parties to determine the appropriate level of participation
by any other persons in any particular meeting or conference. 
 ARTICLE VII 

Cooperation 

Section 7.01 General Cooperation. The Parties shall each cooperate fully (and each shall cause its respective Subsidiaries to
cooperate fully) with all reasonable requests in writing or via e-mail from another Party, or from an agent, representative or advisor to such Party, in connection with the preparation and filing of Tax Returns, claims for Refunds, Tax Proceedings,
Tax ruling requests, and calculations of amounts required to be paid pursuant to this Agreement, in each case, related or attributable to or arising in connection with Taxes of any of the Parties or their respective Subsidiaries covered by this
Agreement and the establishment of any reserve required in connection with any financial reporting (a “Tax Matter”). Such cooperation shall include the provision of any information reasonably necessary or helpful in connection with
a Tax Matter and shall include at each Party’s own cost: 
 (i) the provision, in hard copy and electronic forms, of any
Tax Returns (or proforma returns) of the Parties and their respective Subsidiaries, books, records (including information regarding ownership and Tax basis of property), documentation, and other information relating to such Tax Returns (or proforma
returns), including accompanying schedules, related work papers, and documents relating to rulings or other determinations by Taxing Authorities; 

(ii) the execution of any document (including any power of attorney) reasonably requested by another Party in connection with
any Tax Proceedings of any of the Parties or their respective Subsidiaries, or the filing of a Tax Return or a Refund claim of the Parties or any of their respective Subsidiaries; and 

(iii) the use of the Party’s reasonable best efforts to obtain any documentation in connection with a Tax Matter. 

Each Party shall make its employees, advisors, and facilities available, without charge, on a reasonable and mutually convenient basis in
connection with the foregoing matters in a manner that does not interfere with the ordinary business operations of such Party. 

Section 7.02 Retention of Records. The EFH Parties and Reorganized TCEH shall retain or cause to be retained all Tax Returns,
schedules, and work papers, and all material records or other documents relating thereto in their possession, including all such electronic records, and shall maintain all hardware necessary to retrieve such electronic records, in all cases until
sixty (60) days after the expiration of the applicable statute of limitations (including any waivers or extensions 

  
 25 

 
thereof) of the taxable periods to which such Tax Returns and other documents relate or until the expiration of any additional period that any Party reasonably requests, in writing, with respect
to specific material records and documents. A Party intending to destroy any material records or documents shall provide the other Party with reasonable advance notice and the opportunity to copy or take possession of such records and documents. The
Parties will notify each other in writing of any waivers or extensions of the applicable statute of limitations that may affect the period for which the foregoing records or other documents must be retained. 

Section 7.03 Failure to Perform. If a Party materially fails to comply with any of its obligations set forth in Sections
7.01 or 7.02 upon reasonable request and notice by the other Party, and such failure results in the imposition of additional Taxes, the non-performing Party shall be liable in full for such additional Taxes notwithstanding anything to the
contrary in this Agreement. 
 ARTICLE VIII 

Provisions of EFH Plan; Enforcement 

Section 8.01 Provisions of EFH Plan. 

(a) Each Party agrees not to attempt to seek or to argue that an EFH Plan, or any other restructuring transaction (including a sale pursuant to
Section 363 of the Bankruptcy Code) for any of the EFH Parties, can or should be confirmed or approved by the Bankruptcy Court if (x) the consummation of such an EFH Plan, or any other restructuring transaction (including a sale pursuant
to Section 363 of the Bankruptcy Code) for any of the EFH Parties would reasonably be expected to create a material risk of (A) a Tax-Free Transaction Failure or (B) causing a breach by the EFH Parties of any term or condition of this
Agreement or (y) it provides that any claim (A) arising from a breach by any of the EFH Parties of any term or condition of this Agreement or (B) for indemnification under Section 3.01 is released or deemed discharged
under an EFH Plan. 
 (b) Each Party shall object to and oppose any proposed EFH Plan, or any other restructuring transaction (including a
sale pursuant to Section 363 of the Bankruptcy Code) for any of the EFH Parties that (x) would reasonably be expected to create a material risk of (A) a Tax-Free Transaction Failure or (B) causing a breach by the Parties of any
term or condition of this Agreement or (y) provides that any claim (A) arising from a breach by any of the EFH Parties of any term or condition of this Agreement or (B) for indemnification under Section 3.01, is released
or deemed discharged under an EFH Plan. 
 Section 8.02 Enforcement. 

(a) Until the substantial consummation of an EFH Plan that is consistent with the terms and conditions of this Agreement: 

(i) The Parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not
performed by the EFH Parties in accordance with their specific terms and that monetary damages, even if available, would not 

  
 26 

 
be an adequate remedy therefor. It is accordingly agreed that with respect to each EFH Party, this Agreement shall be enforceable as against such EFH Party by specific performance or other
injunctive relief, without proof of actual damages (and each EFH Party hereby waives any requirement for the securing or posting of any bond in connection with such remedy), in addition to any other remedy available against such EFH Party at law or
equity. Each EFH Party knowingly, voluntarily and unconditionally (i) waives its rights to revoke, terminate, avoid, disaffirm or reject this Agreement, or any portion thereof, pursuant to the Bankruptcy Code or other applicable law, including
Section 365 of the Bankruptcy Code and (ii) agrees that it shall not support, directly or indirectly, and shall oppose, any request by any other party-in-interest to compel, require or otherwise request that this Agreement or any portion
thereof be revoked, avoided, disaffirmed, terminated or rejected for any reason. 
 (ii) Without limiting in any manner the
right to obtain specific performance or other injunctive relief pursuant to Section 8.02(a)(i), if a Party elects to seek monetary damages, any claim against an EFH Party under this Agreement shall be non-dischargeable under any EFH Plan and
entitled to superpriority administrative claim status, junior only to (i) the EFIH First Lien DIP Facility or a future EFIH Second Lien DIP Facility (if any) to the extent the proceeds thereof are used solely to repay the EFIH Second Lien Note
Claims (as defined in the Plan) and for fees and expenses related to such repayment, (ii) the Carve-Out (as defined in the EFIH First Lien DIP Order), and (iii) any of the following fees owed by EFH (subject to the same caps applicable to
the Carve-Out): (A) all fees required to be paid to the Clerk of the Court and to the Office of the United States Trustee under Section 1930(a) of title 28 of the United States Code plus interest at the statutory rate; (B) reasonable
fees and expenses incurred by a trustee under Section 726(b) of the Bankruptcy Code; and (C) to the extent allowed at any time, whether by interim order, procedural order, or otherwise, all unpaid fees and expenses incurred by persons or
firms retained by (1) the EFH Debtors, pursuant to Section 327, 328, or 363 of the Bankruptcy Code, and (2) the EFH/EFIH Committee. 

ARTICLE IX 
 Miscellaneous

 Section 9.01 Governing law. This Agreement and all issues and questions concerning the construction, validity,
enforcement, and interpretation of this Agreement (and all Schedules and Exhibits) shall be governed by, and construed in accordance with, the laws of the State of Delaware, without giving effect to any choice of law or conflict of law rules or
provisions (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware. In furtherance of the foregoing, the internal laws of the State of Delaware
shall control the interpretation and construction of this Agreement (and all Schedules and Exhibits), even though under that jurisdiction’s choice of law or conflict of law analysis, the substantive law of some other jurisdiction would
ordinarily apply. 

  
 27 

 Section 9.02 Dispute Resolution. In the event of any dispute among the Parties as to
any matter covered by Sections 2.02 or 2.04, the Parties shall appoint a nationally recognized independent public accounting firm (the “Accounting Firm”) to resolve such dispute. In this regard, the Accounting Firm
shall make determinations with respect to the disputed items based solely on representations made by the EFH Parties and Reorganized TCEH and their respective representatives, and not by independent review, and shall function only as an expert and
not as an arbitrator and shall be required to make a determination in favor of one Party only. The Parties shall require the Accounting Firm to resolve all disputes no later than thirty (30) days after the submission of such dispute to the
Accounting Firm and agree that all decisions by the Accounting Firm with respect thereto shall be final and conclusive and binding on the Parties. The Accounting Firm shall resolve all disputes in a manner consistent with this Agreement. The Parties
shall require the Accounting Firm to render all determinations in writing and to set forth, in reasonable detail, the basis for such determination. The fees and expenses of the Accounting Firm shall be borne equally by the Parties. For the avoidance
of doubt, any dispute among the Parties as to any matter not covered by Sections 2.02 or 2.04 shall be governed by the provisions set forth in Section 9.15. 

Section 9.03 Tax Sharing Agreements. All Tax sharing, indemnification, and similar agreements, written or unwritten, as between a
Reorganized EFH Entity, on the one hand, and a Reorganized TCEH Entity, on the other (other than this Agreement and any other agreement for which Taxes is not the principal subject matter), shall be or shall have been terminated (and, to the extent
provided under the Plan, settled) no later than the TCEH Effective Date and, after the TCEH Effective Date, no Reorganized EFH Entity or Reorganized TCEH Entity shall have any further rights or obligations under any such Tax sharing, indemnification
or similar agreement, except as provided in the Plan. 
 Section 9.04 Interest on Late Payments. With respect to any payment
among the Parties pursuant to this Agreement not made by the due date set forth in this Agreement for such payment, the outstanding amount will accrue interest at a rate per annum equal to the rate in effect for underpayments under Section 6621
of the Code from such due date to and including the payment date. 
 Section 9.05 Survival of Covenants. Except as otherwise
contemplated by this Agreement, the covenants and agreements contained herein to be performed following the Distribution shall survive the Distribution in accordance with their respective terms. 

Section 9.06 Severability. If any provision of this Agreement or the application of any such provision to any Person or
circumstance shall be declared judicially to be invalid, unenforceable or void, such decision shall not have the effect of invalidating or voiding the remainder of this Agreement, it being the intent and agreement of the Parties that this Agreement
shall be deemed amended by modifying such provision to the extent necessary to render it valid, legal, and enforceable to the maximum extent permitted while preserving its intent or, if such modification is not possible, by substituting therefor
another provision that is valid, legal, and enforceable and that achieves the original intent of the Parties. 
 Section 9.07 Entire
Agreement. This Agreement, the Exhibits, the other Transaction Agreements, the Plan and the other documents referred to herein shall constitute the entire agreement among the Parties with respect to the subject matter hereof and shall supersede
all previous negotiations, commitments, and writings with respect to such subject matter. Except as otherwise expressly provided herein, in the case of any conflict between the terms of this Agreement and the terms of any other agreement, the terms
of this Agreement shall control. 

  
 28 

 Section 9.08 Assignment. This Agreement shall not be assigned or delegated by a Party
(in each case, whether (x) by merger, consolidation or dissolution of a Party, (y) by contract, operation of law or (z) otherwise) without the prior written consent of the other Parties, and any purported assignment or delegation in
violation of this Agreement shall be null and void. Notwithstanding the foregoing, the Parties hereby acknowledge that the surviving entity of any merger involving any Party shall be entitled and subject to all of the rights, benefits and
obligations of the Company pursuant to this Agreement. For purposes of this Section 9.08, the term “merger” refers to any merger in which a Party is a constituent entity, regardless of whether it is the surviving or merged
entity. As a condition to, and prior to the consummation of, any direct or indirect transfer or other disposition of all or substantially all of its assets (whether in a single transaction or a series of related or unrelated transactions) the Party
engaging in such transfer or other disposition shall require the transferee to assume all of such Party’s obligations hereunder. 

Section 9.09 No Third Party Beneficiaries. Nothing in this Agreement, express or implied, is intended to or shall confer upon any
Person (other than the Parties and their respective successors and permitted assigns) any legal or equitable right, benefit or remedy of any nature whatsoever under or by reason of this Agreement, and, except as provided in Article III
relating to certain indemnitees, no Person shall be deemed a third party beneficiary under or by reason of this Agreement. 

Section 9.10 Performance. Each EFH Party shall cause to be performed, and hereby guarantees the performance of, all actions,
agreements, and obligations set forth herein to be performed by an Affiliate of such EFH Party, and each Reorganized TCEH Entity shall cause to be performed, and hereby guarantees the performance of, all actions, agreements, and obligations set
forth herein to be performed by an Affiliate of Reorganized TCEH. 
 Section 9.11 Amendments; Waivers. This Agreement may not be
amended except by an instrument in writing signed by each of the Parties. No failure or delay by any Party in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or
further exercise thereof or the exercise of any other right hereunder. Any agreement on the part of any Party to any such waiver shall be valid only if set forth in an instrument in writing signed on behalf of such Party. 

Section 9.12 Interpretation. The Parties have participated jointly in the negotiation and drafting of this Agreement, and in the
event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties, and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the
authorship of any provisions of this Agreement. 
 Section 9.13 Counterparts. This Agreement may be executed in one or more
counterparts each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by facsimile or
portable document format (PDF) shall be as effective as delivery of a manually executed counterpart of any such Agreement. 

  
 29 

 Section 9.14 Confidentiality. Each Party shall hold and cause its directors,
officers, employees, advisors, and consultants to hold in strict confidence, unless compelled to disclose by judicial or administrative process or, in the opinion of its counsel, by other requirements of law, all information (other than any such
information relating solely to the business or affairs of such party) concerning the other Party furnished it by such other Party or its representatives pursuant to this Agreement (except to the extent that such information can be shown to have been
(a) in the public domain through no fault of such Party or (b) later lawfully acquired from other sources not under a duty of confidentiality by the party to which it was furnished), and no Party shall release or disclose such information
to any other Person, except its directors, officers, employees, auditors, attorneys, financial advisors, bankers or other consultants who shall be advised of and agree to be bound by the provisions of this Section 9.13. Each Party shall
be deemed to have satisfied its obligation to hold confidential information concerning or supplied by the other Party if it exercises the same care as it takes to preserve confidentiality for its own similar information. Except as required by law or
with the prior written consent of the other Party, all Tax Returns, documents, schedules, work papers and similar items and all information contained therein, and any other information that is obtained by a Party or any of its Affiliates pursuant to
this Agreement, shall be kept confidential by such Party and its Affiliates and representatives, shall not be disclosed to any other Person, and shall be used only for the purposes provided herein. If a Party or any of its Affiliates is required by
law to disclose any such information, such Party shall give written notice to the other Party prior to making such disclosure. 

Section 9.15 Waiver of Jury Trial. AS A SPECIFICALLY BARGAINED INDUCEMENT FOR EACH PARTY TO ENTER INTO THIS AGREEMENT (WITH EACH
PARTY HAVING HAD OPPORTUNITY TO CONSULT COUNSEL), EACH PARTY EXPRESSLY AND IRREVOCABLY WAIVES THE RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING UNDER THIS AGREEMENT OR ANY ACTION OR PROCEEDING ARISING OUT OF THE TRANSACTIONS CONTEMPLATED
HEREBY OR ANY OTHER TRANSACTION AGREEMENT, REGARDLESS OF WHICH PARTY INITIATES SUCH ACTION OR PROCEEDING, AND ANY ACTION OR PROCEEDING UNDER THIS AGREEMENT OR ANY ACTION OR PROCEEDING ARISING OUT OF THE TRANSACTIONS CONTEMPLATED HEREBY OR ANY OTHER
TRANSACTION AGREEMENT SHALL BE TRIED IN A COURT OF COMPETENT JURISDICTION BY A JUDGE SITTING WITHOUT A JURY. 
 Section 9.16
Jurisdiction; Service of Process. Any action with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations
arising hereunder brought by a Party or its successors or assigns, in each case, shall be brought and determined exclusively in the Bankruptcy Court (or, if the Bankruptcy Court declines to accept jurisdiction over a particular matter, then the
Chancery Court of the State of Delaware, and if the Chancery Court of the State of Delaware declines jurisdiction, then any state or federal court sitting in Delaware). Each Party hereby irrevocably waives, and agrees not to assert, by way of
motion, as a defense, counterclaim or otherwise, in any Action with respect to this Agreement (a) any claim that is not personally subject to the jurisdiction of the above named courts for any reason other than the failure to serve in
accordance with this Section 9.15, (b) any claim that it or its property is exempt or immune from 

  
 30 

 
jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment,
execution of judgment or otherwise), and (c) to the fullest extent permitted by applicable law, any claim that (i) the Action in such court is brought in an inconvenient forum, (ii) the venue of such Action is improper or
(iii) this Agreement, or the subject matter hereof, may not be enforced in or by such courts. Each Party further agrees that no Party to this Agreement shall be required to obtain, furnish or post any bond or similar instrument in connection
with or as a condition to obtaining any remedy referred to in this Section 9.15 and each Party waives any objection to the imposition of such relief or any right it may have to require the obtaining, furnishing or posting of any such
bond or similar instrument. The Parties hereby agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 9.16, or in such other manner as may be permitted by law,
shall be valid and sufficient service thereof and hereby waive any objections to service accomplished in the manner herein provided. NOTWITHSTANDING THIS SECTION 9.15, ANY DISPUTE REGARDING SECTIONS 2.02 OR 2.04 SHALL BE
RESOLVED IN ACCORDANCE WITH SECTION 9.02; PROVIDED, THAT THE TERMS OF SECTION 9.02 MAY BE ENFORCED BY EITHER PARTY IN ACCORDANCE WITH THE TERMS OF THIS SECTION 9.15. 

Section 9.17 Notices. All notices, requests, claims, demands, and other communications to be given or delivered under or by the

prepaid), provided that confirmation of delivery is received, (c) upon machine-generated acknowledgment of receipt after transmittal by facsimile or (d) five (5) days after being mailed to the recipient by certified or registered mail

 Any
Party to this Agreement may notify any other Party of any changes to the address or any of the other details specified in this paragraph; provided, that such notification shall only be effective on the date specified in such notice or five
(5) Business Days after the notice is given, whichever is later. Rejection or other refusal to accept or the inability to deliver because of changed address of which no notice was given shall be deemed to be receipt of the notice as of the date
of such rejection, refusal or inability to deliver. Any notice to any EFH Party will be deemed notice to all the Reorganized EFH Entities, and any notice to Reorganized TCEH will be deemed notice to all the Reorganized TCEH Entities. 

Section 9.18 Headings. The headings and captions of the Articles and Sections used in this Agreement and the table of contents to
this Agreement are for reference and convenience purposes of the Parties only, and will be given no substantive or interpretive effect whatsoever. 

Section 9.19 Effectiveness. 

(a) Subject to Section 9.18(b), this Agreement shall become effective upon the Distribution or the consummation of the Taxable
Separation, as appropriate. 
 (b) Notwithstanding anything contained in this Agreement to the contrary, this Agreement shall be null, void,
and of no force or effect, without any action required by any Party, (i)

  
 33 

 
in the event of a Taxable Separation, unless EFH has received a private letter ruling (or a legally binding agreement with the IRS, including a closing agreement) that income realized upon the
cancellation of the TCEH First Lien Claims will be excluded from EFH’s gross income pursuant to Section 108(a)(1)(A); and (ii) in the event of a Spin-Off, unless EFH has received a private letter ruling (or a legally binding agreement
with the IRS, including a closing agreement), that (A) subject to the penultimate sentence of this Section 9.18(b), income realized upon the cancellation of the TCEH First Lien Claims will be excluded from EFH’s gross income
pursuant to Section 108(a)(1)(A); or that (B) (x) assuming the Distribution satisfies the requirements of Section 368(a)(1)(G) and Section 355, EFH will recognize no income or gain from the cancellation of the TCEH First
Lien Claims; and (y) no amount of the TCEH debt will be treated as having been (1) assumed by [Reorganized TCEH] pursuant to Section 357(c) and Section 357(d) or (2) treated as an amount realized in connection with the
Preferred Stock Sale. In the event that this Agreement becomes null, void and of no force or effect pursuant to the foregoing sentence, the holders of TCEH First Lien Claims reserve all rights to seek Bankruptcy Court approval of a Taxable
Separation or a Spin-Off that includes the Preferred Stock Sale, and EFH and EFIH reserve all rights to object to such transactions. In the event the IRS informs the Parties that a ruling or rulings required by this Section 9.18(b) are
not provided on the basis that such ruling does not present a significant issue, the requirement to obtain such rulings can be satisfied by the provision of a “will” opinion to EFH, in form and substance satisfactory to the EFH Parties and
Reorganized TCEH, without substantive qualifications, of a nationally recognized law or accounting firm, which firm is reasonably acceptable to the EFH Parties and Reorganized TCEH, addressing the matter covered by such rulings. For the purposes of
such opinion, each of the EFH Parties and Reorganized TCEH acknowledges that Paul, Weiss, Rifkind, Wharton & Garrison LLP, Kirkland & Ellis LLP and KPMG LLP are reasonably acceptable to such entity. 

(c) This Agreement shall not become effective with respect to Merger Sub or Parent until the Merger is consummated. 

Section 9.20 Further Assurances. The EFH Parties shall cause each other Person that is or becomes a Subsidiary of EFH (other than
any such Person or Subsidiary that is “ring fenced,” including the Oncor Entities) to execute a joinder to this Agreement (a) to become an EFH Party (effective as of the date such Person becomes a Subsidiary of EFH or ceases to be
“ring fenced”) and (b) to be bound by the obligations of the EFH Parties under this Agreement on a joint and several basis. Reorganized TCEH shall cause each Reorganized TCEH Entity on the date of this Agreement (y) to execute a
joinder to this Agreement to become a Reorganized TCEH Entity (effective as of the date of this Agreement) and (z) to be bound by the obligations of the Reorganized TCEH Entities under this Agreement on a joint and several basis.

NOW, THEREFORE, in consideration of the premises, the covenants and agreements set forth herein, the mutual benefits to be
gained by the performance thereof and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound, the Parties hereby agree as follows: 

ARTICLE 1 - SERVICES 
 1.1
Transition Services. 
 (a) During the Term, OpCo hereby agrees to provide, or cause to be provided (whether through one or more of
its Subsidiaries or as permitted pursuant to Section 1.2), to the Company and its Subsidiaries upon the terms and subject to the conditions set forth in this Agreement (i) the services described on Annex A attached hereto (the
“Service Schedule”), (ii) as reasonably requested by the Company, any other service historically provided to the Company and/or its Subsidiaries during the period from April 29, 2014 through the date hereof by EFH Corporate
Services, OpCo and/or their respective Subsidiaries, or (iii) if applicable, other services that may be agreed upon by the Parties in writing after the date hereof (“Additional Services” and, together with the services in
clauses (i) and (ii), the “Transition Services”). In the event that the Parties identify and agree upon Additional Services to be provided under this Agreement, the Parties shall execute an amendment to this Agreement that
provides for the substitution of the relevant Service Schedule, or additions or supplements to the relevant Service Schedule, in order to describe such Additional Services and other specific terms and conditions applicable thereto. 

  
 2 

 (b) Notwithstanding the foregoing, during the Term, the Parties agree, subject to Article
6 hereof, that the Transition Services include, to the extent applicable, the transitioning of information of the Company and its Subsidiaries to the Company and its Subsidiaries that such Company and/or Subsidiary reasonably require to operate
their businesses (including historical books and records and electronic and other data related to the business of the Company and its Subsidiaries). 

(c) In no event shall OpCo or its Affiliates be required to (i) lend any funds to the Company or its Affiliates or (ii) make any payments
or disbursements on behalf of the Company, except to the extent the Company has previously delivered to OpCo sufficient funds to make any such payment or disbursement. 

(d) Subject to Section 1.1(f), unless otherwise expressly required under the terms of any relevant Service Schedule hereto, the Tax
Matters Agreement, the Separation Agreement, the Split Participant Agreement, or as otherwise agreed to by the Parties in writing, in providing the Transition Services, OpCo or its Affiliates shall not be obligated to: (i) expend funds and other
resources beyond levels that would be customary and reasonable for any other nationally recognized service provider to perform services that are similar to the relevant Transition Services; (ii) maintain the employment of any specific employee or
subcontractor; (iii) purchase, lease or license any additional (measured as of the date hereof) equipment or materials (expressly excluding any renewal or extension of any leases or licenses required for OpCo to perform the relevant Transition
Services during the Term; provided, that such extension or renewal shall be subject to Section 3.1 in all respects); or (iv) pay any of the Company’s costs related to its or any of its Affiliates’ receipt of the Transition
Services. 
 (e) The Parties acknowledge the transitional nature of the Transition Services. In this regard, the Company acknowledges and
agrees that it has the responsibility for the daily and strategic management of the Company and its Subsidiaries and that the intent of this Agreement and the extent of the Transition Services to be provided hereunder are for OpCo solely to provide,
during the Term, the back-office and administrative services necessary to support the on-going daily operations of the Company and its Subsidiaries in a reasonably prudent manner. Given the transitional nature of the Transition Services, the Company
acknowledges and agrees that OpCo may make changes from time-to-time in the personnel performing the Transition Services, subject to Section 1.1(f). 

(f) Nothing in Section 1.1(d) or Section 1.1(e) shall alter the obligations of OpCo to provide the Transition Services during
the Term in accordance with the other provisions of this Agreement, including with regard to type, skill, care, quantity, scope, timeliness and diligence as provided in Section 1.4(a). 

1.2 Personnel; Third-Party Providers. 

(a) OpCo hereby agrees, except as otherwise provided in this Section 1.2, it will not delegate its responsibilities under this
Agreement to any unaffiliated third Person (a “Third-Party Provider”) without the Company’s express prior written consent (such consent not to be unreasonably withheld, conditioned, or delayed; it being understood that it would
be reasonable for the Company not to consent to any delegation that would adversely change in any material respect the obligations of the Company under this Agreement (including any delegation that would obligate the Company to provide any
incremental credit support or that would materially increase the cost of the services subject to such delegation)). Notwithstanding the foregoing, the Parties acknowledge and agree that the Transition Services that have historically been provided
and supported by Third-Party Providers may be provided and supported without the consent of the Company; provided that such Third-Party Provider provision and support does not alter the obligations of OpCo to provide the Transition Services
during the Term in accordance with this Agreement, including with regard to type, skill, care, quantity, scope, timeliness and 

  
 3 

 
diligence as provided in Section 1.4(a); provided, further, that, without the prior written consent of the Company (which consent may be withheld, conditioned or delayed in
the Company’s sole discretion), in no event shall OpCo enter into any arrangement or contract with a Third-Party Provider (1) in the name of the Company (or any of its affiliates) on its behalf or (2) that would reasonably be expected to result
in the Company (or any of its affiliates) being required to make, directly or indirectly, any payments to such Third-Party Provider (or to Opco for services provided by any Third-Party Provider) following completion of the Transition Services
(except, for the avoidance of doubt, any payments to OpCo for Transition Services performed in accordance with this Agreement prior to the completion of the Transition Services which may not have been paid but are otherwise due and payable in
accordance with this Agreement).
 (b) In the event OpCo or a Third-Party Provider requires incremental credit support in connection with
the provision of Transition Services, OpCo may request that the Company provide reasonable credit support to OpCo or such Third Party Provider with respect thereto. In the event that the Company elects not to provide such requested credit
support (which it may do in its sole discretion), the Company agrees that the fees to be charged hereunder shall include any reasonable and documented incremental cost and expense that OpCo or such Third Party Provider incurs in connection with
providing OpCo or such Third-Party Provider the required credit support for the applicable Transition Services. 
 (c) OpCo shall perform
its obligations under this Agreement as an independent contractor. No employees or representatives of OpCo or a Third-Party Provider shall be deemed to be employees or representatives of the Company. In performing the Transition Services, such
employees and representatives of OpCo or a Third-Party Provider shall be under the direction, control and supervision of OpCo or the Third-Party Provider, as applicable, and, subject to compliance with the requirements set forth in the Service
Schedule. OpCo or the Third-Party Provider, as applicable, shall be solely responsible for exercising all authority with respect to, and shall bear all liabilities arising from, the employment (including termination of employment), assignment and
compensation of such employees or representatives (including the payment of all salary and benefits and all premiums and remittances with respect to employees used to provide any Transition Services hereunder). 

(d) If a Third-Party Provider provides Transition Services in accordance with this Agreement, such Third-Party Provider shall be a
subcontractor engaged by OpCo. OpCo shall cause each such Third Party Provider to be subject to service standards and confidentiality provisions at least equivalent to those set forth herein. OpCo shall remain responsible for the
performance by it of all of its obligations hereunder with respect to the Transition Services provided by such Third-Party Provider. 
 1.3
Third Party Consents. 
 (a) The Parties acknowledge and agree that it may be necessary to obtain from third parties certain
consents, waivers, permits, licenses or sublicenses (“Consents”) in order for (i) OpCo to use third-party applications, Intellectual Property, systems, networks and similar services and functions in the provision of Transition
Services and/or (ii) the Company to receive Transition Services. 
 (b) The Parties will cooperate and use their respective commercially
reasonable efforts to obtain the Consents; provided, however, that the failure to obtain any such Consent shall not relieve OpCo of its obligation to provide the relevant Transition Service unless (A) the provision of such Transition Service
is prohibited by applicable Law or (B) such Consent cannot be obtained in a timely manner after using commercially reasonable efforts. In either case of clauses (A) or (B) in the preceding sentence, OpCo shall promptly notify the Company thereof and
the Parties will use their commercially reasonable efforts to implement an alternative means of continuing the provision of the applicable Transition Service for which the Consent is required, in accordance with the service standards described in
Section 1.4. Each Party shall use commercially reasonable efforts to mitigate the effects (including the cost) of such alternative means. 

  
 4 

 1.4 Level of Service and Limitations. 

(a) During the Term, OpCo shall perform, or cause to be performed, the Transition Services (i) in a professional and workmanlike manner at a
quality substantially equivalent (including with regard to type, skill, care, quantity, scope, timeliness and diligence) as provided by EFH Corporate Services and/or any of its Subsidiaries in the ordinary course of business during the twelve (12)
month period prior to the Petition Date (or, to the extent new services commenced following the Petition Date, during the twelve (12) month period prior to the Effective Date) and (ii) in compliance with all applicable Laws, in all material
respects. 
 (b) During the Term, the Company shall (i) use commercially reasonable efforts to terminate its need to receive the Transition
Services as soon as commercially practicable after the Effective Date and (ii) allow representatives of OpCo reasonable access to its employees, facilities, assets, advisors, systems and information as reasonably requested by OpCo for purposes of
rendering the Transition Services under this Agreement; provided, that no such access shall unreasonably interfere with the ongoing operations of the Company and its Subsidiaries; and provided, further, that the Company may
exclude any OpCo personnel at its sole discretion from access to any of its employees, facilities, assets, advisors, systems and/or information due to a material violation by OpCo personnel of the Company’s reasonable health, safety, data
security, conduct or other policies. 
 (c) In connection with its provision of the Transition Services under this Agreement, OpCo shall be
permitted to rely on any written information or data provided by the Company, its Subsidiaries or its Representatives, to OpCo, except to the extent that OpCo has actual knowledge that such information or data is inaccurate. 

(d) Notwithstanding anything to the contrary contained herein, OpCo shall not be obligated to (and shall not be obligated to cause any Third
Party Provider to) provide any Transition Services if the provision of such Transition Services would (i) violate any Law or (ii) with respect to legal, accounting or similar professional services, violate or be in contravention of any rules,
regulations or standards of practice promulgated by any organization or authority governing such professional service; provided, however, in each case, that the Parties shall work diligently together in good faith to obtain or cause to be
obtained such Transition Services (including, if applicable, professional services) from another provider on a commercially reasonable basis. 

(e) During the Term, each Party agrees to use commercially reasonable efforts to cooperate with the other Party in all matters relating to the
provision and receipt of the Transition Services and to effect an orderly transition of the Transition Services. This Agreement is a purely commercial transaction between the Parties and nothing stated in this Agreement shall operate to create any
partnership, or special or fiduciary duty between the Parties. 
 1.5 Project Managers. OpCo and the Company shall each appoint one
or more individuals to act as project managers (each, a “Project Manager”) to (i) serve as the primary contact for any issues arising out of the performance of this Agreement or any portion of the Transition Services and (ii)
be primarily responsible for administering the orderly provision or receipt, as applicable, of the Transition Services (or applicable portion thereof) on its behalf. The initial Project Managers, as well as their respective addresses for notices and
other communications, are set forth in the Service Schedule. Each Party agrees to provide reasonable access (in person, by telephone or electronically via e-mail) during normal business hours to its Project Manager for problem resolution. Either
Party may replace its Project Manager at any time by providing notice in accordance with Section 7.5, such replacement to be effective as of the date of the other Party’s receipt of such notice. 

  
 5 

 1.6 No Service Warranty. Except to the extent provided in Section 1.2(d) and
Section 1.4(a), OpCo makes no warranties or representations relating to the Transition Services or the results of the Transition Services hereunder and hereby disclaims all representations or warranties, whether express, implied or statutory,
with respect to its performance under this Agreement, including without limitation any warranty of adequacy, merchantability or fitness for a particular purpose. 

1.7 No Conflicts. OpCo hereby represents and warrants to the Company that, except as set forth on Annex B attached
hereto, to the knowledge of OpCo (after reasonable inquiry) (i) the execution and delivery of this Agreement by OpCo and (ii) the performance by OpCo of its obligations under this Agreement do not violate, in any material respect, applicable Law .

 ARTICLE 2 - TERM AND TERMINATION 

2.1 Term. The term of this Agreement shall commence on the Effective Date and shall continue until the earlier of (i) the date that is
twelve (12) months from the Effective Date for tax services referred to in Annex A or six (6) months from the Effective Date for other Transition Services and (ii) the termination of all Transition Services pursuant to Section
2.2 or Section 2.3 (the “Term”). At the end of the Term all rights and obligations under this Agreement shall cease, except (a) the rights and obligations that are expressly stated to survive termination pursuant to
Section 2.4 and (b) rights and obligations that have accrued prior to such termination, including the obligation to pay any amounts that have become due and payable prior to such termination. 

2.2 Discontinuation of Services. During the Term, the Company may terminate any particular Transition Service (whether provided
directly or indirectly by OpCo and/or any of its Affiliates or by any Third-Party Provider) and eliminate it from the scope of the Transition Services provided under this Agreement upon at least thirty (30) days’ (or such other amount of time
as mutually agreed in writing between the Parties) prior written notice to OpCo, and following such termination the Company shall only be liable to OpCo for the Fees (as defined below) owed to OpCo in connection with, and attributable to, the
provision of such discontinued Transition Services to the extent attributable to the period on and before such discontinuation. During the Term, the Parties shall cooperate as reasonably required to effectuate an orderly and systematic transfer to
the Company, or any such Person at the request of the Company, of all of the duties and obligations previously performed by OpCo (whether provided directly or indirectly by Opco and/or any of its Affiliates or by any Third-Party Provider) under this
Agreement that the Company desires to continue following the Term. 
 2.3 Early Termination. 

(a) Notwithstanding anything in this Agreement to the contrary, this Agreement or any particular Transition Service may be terminated prior to
the expiration of the Term as follows: 
  

	 	(i)	with respect to any particular Transition Service, by the Company pursuant to Section 2.2; 

  

	 	(ii)	by mutual written consent of the Company and OpCo; or 

  

	 	(iii)	 by the Company, on the one hand, or OpCo, on the other hand, if the other Party is in material breach of any of
its covenants or obligations set forth in this Agreement and fails to cure such breach as promptly as 

  
 6 

	 	
reasonably practicable but in any event within twenty (20) Business Days (or ten (10) Business Days with respect to any failure to make a required payment under this Agreement that is not subject
to a good faith dispute pursuant to Section 3.3) after receipt of written notice thereof from the other Party (which notice must specify, in reasonable detail, the nature of such breach). 

2.4 Survival. The termination of this Agreement with respect to any particular Transition Service pursuant to Section 2.2 or
Section 2.3 shall not affect the provisions of this Agreement and the Service Schedule with respect to a Transition Service not terminated. Neither the termination of this Agreement with respect to any particular Transition Service pursuant
to Section 2.2 or Section 2.3 nor the expiration of the Term shall affect (i) the liability of a Party for a breach of this Agreement prior to the termination or expiration hereof, (ii) the Parties’ obligations set forth in this
Section 2.4, Article 5, Article 6 and Article 7, which shall survive any termination or expiration of this Agreement and (iii) any rights or obligations arising out of or in connection with this Agreement that have
vested, matured or accrued prior to such termination or expiration, including, the right of OpCo to receive any and all amounts owed to OpCo hereunder to the extent attributable to the period on and before such termination or expiration. 

ARTICLE 3 - COMPENSATION 

3.1 Fees. In consideration for the provision of the Transition Services, the Company shall pay to OpCo all reasonable and documented
fees, costs, and expenses (including employee-related, overhead, general and administrative expenses) incurred by OpCo related directly to the Transition Services provided during the Term, plus a twenty-five percent (25%) additional mark-up on all
such fees, costs and expenses, excluding from the mark-up all fees, costs and expenses invoiced, directly or indirectly, by any Third-Party Provider (which for the avoidance of doubt will be payable by the Company solely at the amount invoiced by
the Third-Party Provider) (collectively, the “Fees”). Annex C attached hereto sets forth a good faith “ballpark” estimate of all Fees that OpCo expects the Company will incur under this Agreement during the
Term for the Transition Services that OpCo expects will be required to support the on-going daily operations of the Company and its subsidiaries in a reasonably prudent manner (it being understood that such the amounts set forth on Annex
C are an estimate and the actual Fees to be incurred may differ from such estimate and OpCo shall, except as otherwise provided under this Agreement, have no liability solely as a result of such difference). 

3.2 Invoices. Within ten (10) Business Days after the end of each calendar month, OpCo (on behalf of itself and each of its
Subsidiaries providing Transition Services) shall submit an invoice (each, an “Invoice”) to the Company setting forth (i) a reasonably detailed description of the Transition Services provided by OpCo and its Subsidiaries during such
calendar month and (ii) reasonable documentation and supporting detail of the Fees owing for such Transition Services (including any third-party invoices related thereto). 

3.3 Time of Payment; Disputes; Interest; No Deductions. 

(a) The Company shall pay, or cause to be paid, all undisputed amounts due under this Agreement within thirty (30) days after receipt of the
applicable Invoice. Such payment shall be made in immediately available funds by bank wire transfer to an account designated by OpCo. 
 (b)
The Company shall promptly (and in no event later than thirty (30) days following receipt of any Invoice) notify OpCo of any good faith objection of the Company with regard to such Invoice and the failure to so object shall be definitive evidence of
the acceptance of such Invoice. If requested by the Company, OpCo shall promptly furnish reasonable documentation to substantiate the 

  
 7 

 
amounts invoiced, including listing the date(s), time(s) and amount(s) of the Transition Services in question. Following any good faith invoice objection, the Company and OpCo shall cooperate in
good faith and use commercially reasonable efforts to resolve any remaining dispute expeditiously, without prejudice to either Party’s rights under Section 7.3 or Section 7.8. The Company shall pay all disputed amounts in
accordance with the resolution of such disputed amount within five (5) Business Days after such resolution. 
 (c) If the Company has not
paid any undisputed amounts within thirty (30) days after receipt of the applicable Invoice with respect thereto, such undisputed amounts shall accrue interest at the lesser of (i) the maximum rate allowed by applicable Law, and (ii) the prime rate
published in The Wall Street Journal plus 4% per annum, and the Company shall pay OpCo such accrued interest. Notwithstanding the foregoing, the failure of the Company to pay any material undisputed amounts within thirty (30) days after
receipt of the applicable Invoice with respect thereto shall also constitute a material breach of this Agreement. 
 3.4 Taxes. 

(a) All Fees shall be exclusive of any goods and services taxes, value added taxes or similar taxes on the performance or delivery of
Transition Services (collectively “Sales Taxes”). 
 (b) To the extent that OpCo is obligated to collect and remit any
Sales Tax in respect of the Transition Services herein provided, the Company shall pay the amount of such Sales Taxes to OpCo in addition to the Fees otherwise payable hereunder. Any amount required to be paid under this Section 3.4(b) and
not paid by the due date for payment shall be subject to the late charges specified in Section 3.3(c). 
 (c) Subject to Section
3.4(b), OpCo shall be responsible for and shall pay all taxes, assessments or other charges against it in connection with the Transition Services, including taxes on OpCo’s income or profits thereon and all taxes imposed on or assessed or
levied against or on account of salaries or other compensation or other benefits or amounts paid or provided to OpCo’s employees or subcontractors. OpCo accepts full and exclusive liability for and shall indemnify, defend and hold the Company
harmless from and against any and all claims arising out of income or payroll taxes or withholding taxes assessed or levied in respect of the provision of Transition Services hereunder by any Governmental Entity. 

(d) OpCo shall not be reimbursed for any (i) real or personal property taxes on property it owns or leases, (ii) franchise, margin, privilege
or similar taxes on its business, (iii) payroll or employment taxes of its employees (including income tax, social security taxes, unemployment compensation, workers’ compensation tax, other employment taxes or withholdings), (iv) taxes based
on its income or gross receipts or (v) withholding taxes. Should there be any withholding tax required for payment made hereunder, the Company shall have the right to withhold such amount from money due to OpCo under this Agreement for payment of
taxes, assessment or other charges. Such payment by the Company shall relieve the Company of further obligation with respect to any amount withheld and OpCo shall assist the Company by submitting the necessary documents to support the application
for the Company to recover such amount later, if applicable. 
 (e) Within thirty (30) days after receiving notification of the commencement
of any Sales Tax, VAT or other similar tax audit by a tax authority which involves the provision of any Transition Services or access to any facilities provided hereunder, the Party receiving such notice shall notify the other Party of such audit.
Thereafter, the Party receiving such notice shall control all proceedings taken in connection with such Sales Tax or VAT or other similar tax audit and shall take 

  
 8 

 
reasonable steps to keep the other Party informed of the progress of any such audit; provided, however, that where the other Party is liable to pay an amount in respect of such Sales Tax,
VAT or other similar tax pursuant to this Section 3.4, the controlling Party shall not settle or otherwise compromise such audit without the other Party’s consent. The other Party shall have the right (but not the duty) to participate in
any proceeding to contest Sales Tax, VAT or other similar liability, and shall have the right to retain tax advisers or counsel at its own expense. 

(f) Subject to applicable Law, the Parties shall use commercially reasonable efforts to cooperate with each other in connection with obtaining
any available reduction of, or exemption from, any taxes due in respect of the provision of Transition Services to the extent possible. 

ARTICLE 4 - FORCE MAJEURE 

4.1 Force Majeure. 
 (a)
If any Party is rendered unable, wholly or in part, by Force Majeure (as defined below) to carry out its obligations under this Agreement, other than obligations to make monetary payments, that Party shall give the non-affected Party prompt written
notice of the cause and extent of the Force Majeure, the date of commencement thereof and the means proposed to be adopted to remedy or abate such Force Majeure, following which the affected Party shall be excused from performance of its obligations
under this Agreement solely to the extent, and for the period, that such performance is prevented by such Force Majeure. The affected Party shall use commercially reasonable diligence to remove or remediate the Force Majeure as quickly as possible
and shall use commercially reasonable efforts to develop a mutually satisfactory solution to such Force Majeure with the non-affected Party. If any Transition Service is interrupted or suspended due to an event of Force Majeure, (i) the Company
shall be entitled to an equitable reduction of Fees payable for the affected Transition Services and (ii) the Company shall have the right to immediately terminate the affected Transition Service and/or any Transition Service linked to the affected
Transition Service. 
 (b) The term “Force Majeure” shall mean any act of God, industry wide strikes directly impacting the
Transition Services, act of the public enemy, war, blockade, terrorism, public riot, lightning, fire, storm, flood, explosion, governmental action, or other circumstance that is beyond the reasonable control of the affected Party and which did not
arise from the fraud, bad faith, intentional or willful misconduct or gross negligence of the affected Party.

ARTICLE 6 - CONFIDENTIALITY 

6.1 Confidential Information. 

(a) For purposes of this Agreement, “Business Information” means all confidential or proprietary business, financial or
technical data, documents, plans, intellectual property and other information, in whatever form, relating to the operations, businesses or assets of a Party or its Affiliates (the “Discloser”) that is disclosed to, or received by,
the other Party (the “Recipient”) in connection with the services or arrangements contemplated by this Agreement. Each Recipient shall, and shall cause its Affiliates, directors, officers, employees, and contractors and its and
their Representatives to, hold the Business Information of the Discloser in confidence and not to use or disclose such Business Information, except as reasonably required for the purposes of this Agreement or otherwise expressly permitted hereunder.
Each Party (as the Recipient) shall use no less than the same degree of care that it uses to protect its own confidential information of similar sensitivity to protect the Business Information of the other Party, but in no event less than a
commercially reasonable degree of care. The restrictions of this Article 6 shall not apply to Business Information that: 
  

	 	(i)	is or becomes generally available to the public other than as a result of a violation of this Section 6.1 by the Recipient or its Affiliates, directors, officers, employees, or contractors or its or their
Representatives; 

  
 11 

	 	(ii)	is developed by the Recipient or its Affiliates, directors, officers, employees, or contractors or its or their Representatives without the use of or reference to any of the Discloser’s Business Information;

  

	 	(iii)	is rightfully obtained by the Recipient or its Affiliates, directors, officers, employees, or contractors or its or their Representatives from a third-party source which such Person reasonably believes was not subject
to any legal, contractual or fiduciary duty to the Discloser; or 

  

	 	(iv)	is identified in writing by the Discloser as no longer proprietary or confidential. 

 (b)
Nothing herein shall prevent a Recipient or its Affiliates, directors, officers, employees, or contractors or its or their Representatives from disclosing Business Information (i) as required by applicable Law or upon the order of any court or
administrative agency, (ii) upon the request or demand of, or pursuant to any regulation of, any regulatory agency or authority (including any self-regulatory agency, stock exchange or quotation system), (iii) to the extent reasonably required in
connection with the exercise of any remedy hereunder in connection with the conduct or defense of any 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) (each, an “Action”), (iv) to its Affiliates, directors, officers, employees, or contractors or its or their Representatives as
necessary to perform the Transition Services pursuant to the terms of this Agreement, provided that such Persons are informed of the confidential nature of the Business Information, and the Recipient shall be liable to the Discloser for the
use or disclosure thereof by such Person in violation of the terms hereof; provided, further, that if Recipient or its Affiliates, directors, officers, employees, or contractors or its or their Representatives is requested or required
pursuant to clause (i) or (ii) to disclose any Business Information of the Discloser, such Recipient shall notify the Discloser promptly in writing, to the extent permitted by applicable Law, of such requirement so that the Discloser may seek a
protective order or other appropriate remedy or waive compliance with this Article 6, and the Recipient or its Affiliates, directors, officers, employees, or contractors or its or their Representatives (as applicable) shall disclose only that
portion of such Business Information which it believes in its reasonable judgment is legally required to be disclosed and shall use its commercially reasonable efforts to obtain assurances that confidential treatment shall be accorded such Business
Information. 
 6.2 Length of Confidentiality Obligation. Each Party agrees to maintain and protect the confidentiality of the
Business Information of the other Party as set forth in this Article 6 during the Term and for two (2) years after the expiration of the Term. 

ARTICLE 7 - MISCELLANEOUS 

7.1 Waiver of Compliance. Any failure of OpCo, on the one hand, or the Company, on the other hand, to comply with an obligation,
covenant, agreement or condition contained in this Agreement may be expressly waived in writing by the non-failing Party, but such waiver or failure to insist upon strict compliance shall not operate as a waiver of, or estoppel with respect to, any
subsequent or other failure. 

  
 12 

 7.2 Waiver of Jury Trial. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH
MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY
OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (i) NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT
SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (ii) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH PARTY MAKES THIS WAIVER VOLUNTARILY, AND
(iv) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 7.2. 

7.3 Governing Law and Venue. THIS AGREEMENT, TOGETHER WITH ANY CLAIM, DISPUTE, REMEDY OR LEGAL PROCEEDING ARISING FROM OR RELATING TO
THIS AGREEMENT OR ANY RELIEF OR REMEDIES SOUGHT BY THE PARTIES, AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER, SHALL BE CONSTRUED, PERFORMED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE, WITHOUT GIVING EFFECT TO ITS
PRINCIPLES OR RULES OF CONFLICT OF LAWS TO THE EXTENT SUCH PRINCIPLES OR RULES WOULD REQUIRE OR PERMIT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION. Each of the Parties (i) submits to the exclusive jurisdiction of the Bankruptcy Court
(or, if the Bankruptcy Court declines to accept jurisdiction over a particular matter, then the Chancery Court of the State of Delaware, and if the Chancery Court of the State of Delaware declines jurisdiction, then any state or federal court
sitting in Delaware) in any Action arising out of or relating to this Agreement, (ii) agrees that all claims in respect of such Action may be heard and determined in any such court and (iii) agrees not to bring any Action arising out of or
relating to this Agreement (whether on the basis of a claim sounding in contract, tort or otherwise) in any other court. Each of the Parties agrees that a final judgment in any such Action shall be conclusive (subject to any appeals therefrom) and
may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. Each of the Parties hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which
it may now or hereafter have to the laying of venue of any Action arising out of or relating to this Agreement or the transactions contemplated hereby in any Delaware or federal court in accordance with the provisions of this
Section 7.3. Each of the Parties hereby irrevocably waives, to the fullest extent permitted by Law, the defense of an inconvenient forum to the maintenance of such Action in any such court. Each of the Parties hereby irrevocably and
unconditionally consents to service of process in the manner provided for notices in Section 7.5. Nothing in this Agreement will affect the right of any Party to serve process in any other manner permitted by Law.

being deemed to be an original instrument, and all such counterparts taken together constituting one and the same agreement.

 7.7 No Third Party Beneficiaries.
Except for the indemnification of members of the Company Group (other than the Company) or members of the Opco Group (other than Opco) set forth in Article V, the Parties hereby agree that their respective covenants and agreements set
forth herein are solely for the benefit of the other Parties and their permitted successors and assigns, 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 and their permitted successors and assigns any rights or remedies hereunder, including the right to rely upon the representations and warranties set forth herein.

 15 

 7.10 Intellectual Property Rights. 

(a) Except as otherwise expressly provided in this Section 7.10, each of OpCo and the Company and their respective
Affiliates shall retain all right, title and interest in and to their respective intellectual property and any and all improvements, modifications and derivative works thereof. No license or right, express or implied, is granted under this Agreement
by OpCo, the Company or their respective Affiliates in or to their respective intellectual property, except that, solely to the extent required for the provision or receipt of the Transition Services in accordance with this Agreement, each of OpCo
and the Company, for itself and on behalf of their respective Affiliates, hereby grants to the other (and their respective Affiliates) a non-exclusive, revocable, non-transferable license during the Term to such intellectual property that is
provided by the granting party to the other party (“Licensee”) in connection with this Agreement, but only to the extent and for the duration necessary for the Licensee to provide or receive the applicable Transition Services as
permitted by this Agreement. Upon the expiration of such time, or the earlier termination of such Transition Service in accordance with this Agreement, the license to the relevant intellectual property will terminate; provided,
however, that all licenses granted hereunder shall terminate immediately upon the expiration or earlier termination of this Agreement in accordance with the terms hereof. The foregoing license is subject to any licenses granted by others with
respect to intellectual property not owned by OpCo, the Company or their respective Affiliates. 
 (b) Subject to the limited
license granted in Section 7.10(a), in the event that any intellectual property is created by OpCo (or a Third-Party Provider, if applicable) in the performance of the Transition Services or provision of access to the facilities, all
right, title and interest throughout the world in and to all such intellectual property shall vest solely in OpCo (or such Third-Party Provider, if applicable) unconditionally and immediately upon such intellectual property having been developed,
written or produced. 
 (c) Except as otherwise expressly provided in this Agreement, none of OpCo (or its Affiliates) and
the Company (or its Affiliates) shall have any rights or licenses with respect to any intellectual property (including software), hardware or facility of the other Party. All rights and licenses not expressly granted in this Agreement or in any
other agreement contemplated by the transactions set forth in the Merger Agreement are expressly reserved by the relevant Party. Each of OpCo and the Company shall from time to time execute any documents and take any other actions reasonably
requested by the other Party to effectuate the intent of this Section 7.10.
 7.11 No Assumption; Other Agreements.
Nothing herein shall be deemed to (a) constitute the assumption by OpCo or any of its Affiliates, or the agreement to assume, any duties, obligations or liabilities of the Company or its Affiliates whatsoever; or (b) alter, amend or otherwise modify
any obligation of the Parties or their Affiliates under the Separation Agreement, the Tax Matters Agreement, the Split Participant Agreement or in any other agreement contemplated by the transactions set forth in the Merger Agreement. 

7.12 Severability. The provisions of this Agreement shall be deemed severable and the invalidity or unenforceability of any provision
shall not affect the validity or enforceability of the other provisions hereof. If any provision of this Agreement, or the application thereof to any Person or any circumstance, is invalid or unenforceable, (a) a suitable and equitable
provision shall be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision and (b) the remainder of this Agreement and the application of such
provision to other Persons or circumstances shall not be affected by such invalidity or unenforceability, nor shall such invalidity or unenforceability affect the validity or enforceability of such provision, or the application thereof, in any other
jurisdiction. 

  
 16 

 7.13 Interpretation; Construction. 

(a) Headings herein are for convenience of reference only, do not constitute part of this Agreement and shall not be deemed to limit or
otherwise affect any of the provisions hereof. Where a reference in this Agreement is made to a section, annex or schedule, such reference shall be to a section of or annex or schedule to this Agreement unless otherwise indicated. Such annexes and
schedules are an integral part of this Agreement and shall be treated as if fully set forth herein. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed
by the words “without limitation.” The words “hereof,” “hereto,” “hereby,” “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as
a whole and not any particular provision of this Agreement. 
 (b) The Parties have participated jointly in negotiating and drafting this
Agreement. In the event that an ambiguity or a question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties, and no presumption or burden of proof shall arise favoring or disfavoring any Party
by virtue of the authorship of any provision of this Agreement. 
 7.14 Assignment; Delegation. This Agreement shall not be assigned
or delegated by a Party (in each case, whether (x) by merger, consolidation or dissolution of a Party, (y) by contract, operation of law or (z) otherwise) without the prior written consent of the other Parties, and any purported assignment or
delegation in violation of this Agreement shall be null and void. Notwithstanding the foregoing, the Company and OpCo hereby acknowledge that, following the Merger, Merger Sub, as the surviving company in the Merger, shall be entitled and subject to
all of the rights, benefits and obligations of the Company pursuant to this Agreement. For purposes of this Section 7.14, the term “merger” refers to any merger in which a Party is a constituent entity, regardless of whether it
is the surviving or merged entity. As a condition to, and prior to the consummation of, any direct or indirect transfer or other disposition of all or substantially all of its assets (whether in a single transaction or a series of related or
unrelated transactions) the Party engaging in such transfer or other disposition shall require the transferee to assume all of such Party’s obligations hereunder. 

7.15 Entire Agreement. This Agreement (which includes the Service Schedule), together with the Merger Agreement, the Separation
Agreement, the Tax Matters Agreement, the Split Participant Agreement and the other agreements contemplated by the Merger Agreement, constitutes the entire agreement, and supersedes all other prior agreements, understandings, representations and
warranties both written and oral, between the Parties, with respect to the subject matter hereof.

 Exhibit I 

Private Letter Ruling and Tax Opinions1 

The following are “Supplemental Rulings”: 
  

	 	(a)	The unsecured EFH Creditors and the unsecured EFIH Creditors, to the extent such creditors receive Common Stock in the EFH Issuances, will be treated as “owners of the enterprise” with respect to EFH for
purposes of Treasury Regulations Section 1.355-2(c)(1). 

  

	 	(b)	Persons receiving Reorganized EFH Common Stock pursuant to the EFH Issuances will not be aggregated for purposes of applying Section 355(d) to the Reorganized TCEH Spin-Off.

 

	 	(c)	In addition to the specific Supplemental Rulings listed above, a ruling in form and substance reasonably satisfactory to the Company and Parent that the Merger does not cause Section 355(d) to apply to the
Reorganized TCEH Spin-Off. A ruling that provides that Parent will not be aggregated with persons receiving Reorganized EFH Common Stock pursuant to the EFH Issuances shall be a reasonably satisfactory ruling for these purposes 

The following are “Fundamental Opinions”: 
  

	 	(a)	The following opinions of nationally recognized tax counsel or a Big Four accounting firm (who shall be permitted to rely upon reasonable representations, including a representation that the Debtors and Reorganized TCEH
have no plan or intention at the time of the Merger to take, and have not taken, any action that is inconsistent with the Spin-Off Intended Tax Treatment), at a “should” level: 

 

	 	(i)	Taking into account the Merger, the Contribution, Reorganized TCEH Conversion, and Distribution should meet the requirements of Sections 368(a)(1)(G), 355, and 356 of the Internal Revenue Code. 

 

	 	(ii)	EFH should not recognize gain for U.S. federal income tax purposes as a result of the Contribution or the Reorganized TCEH Conversion other than gain recognized pursuant to the transfer of assets to the Preferred Stock
Entity and the Preferred Stock Sale. 

  

	 	(iii)	EFH should recognize no gain or loss for U.S. federal income tax purposes upon the Distribution. 

 

	1 	 Terms used but not defined in this Exhibit I shall have the meanings ascribed to them in the Initial
IRS Submissions. 

  
 Exhibit I 

	 	(b)	The following opinion of nationally recognized tax counsel or a Big Four accounting firm (who shall be permitted to rely upon reasonable representations, including a representation that the Debtors and Reorganized TCEH
have no plan or intention at the time of the Merger to take, and have not taken, any action that is inconsistent with the Spin-Off Intended Tax Treatment), at a “will” level that Section 355(g) will not apply to the Reorganized TCEH
Spin-Off.

transfer, convey and deliver to SpinCo or a member of the SpinCo Group designated by SpinCo, and SpinCo or such member of the SpinCo Group, as applicable, shall accept from the Company and such Subsidiaries, the TCEH Assets, and (ii) SpinCo or such
member of the SpinCo Group designated by SpinCo, as applicable, shall accept, assume and agree faithfully to perform, discharge and fulfill all the Assumed Liabilities. 

(b) In furtherance of the transactions described in Section 2.1(a), on the TCEH Effective Date: 

(i) the Company and SpinCo shall, and the Company and SpinCo shall cause their applicable Subsidiaries to, execute assignment
and assumption agreements substantially in the form attached hereto as Exhibit A, and such additional bills of sale, quitclaim deeds, stock or equity powers, certificates of title, assignments of contracts and other instruments of transfer,

 Section 2.2 Approvals and Notifications. 

(a) The Parties will use their commercially reasonable efforts to obtain all material Approvals and Notifications, if any,
necessary to consummate the transactions contemplated by this Agreement, as soon as reasonably practicable, including the Specified Approvals, if any. 

(b) If the transfer or assignment of any Acquired TCEH Assets or assumption of any Assumed Liabilities would violate, in any
material respect, any applicable Law or require any Approvals and Notifications or release which have not been obtained or made, notwithstanding the receipt of the Specified Approvals, then those Acquired TCEH Assets or Assumed Liabilities will be
identified in reasonable detail in a written notice given by any Party that would violate such Law by the transfer or receipt of the Acquired TCEH Assets or the assignment or assumption of the Assumed Liability or require such Approvals and
Notifications or release, and unless the Parties mutually shall otherwise determine, the transfer or assignment of such Acquired TCEH Assets or the assumption of such Assumed Liabilities, as the case may be, shall be automatically deemed deferred
and any such purported transfer, assignment or assumption shall be null and void until such time as all such Approvals and Notifications or releases have been obtained or made. 

(c) If any transfer or assignment of any Acquired TCEH Asset or any assumption of any Assumed Liability intended to be
transferred, assigned or assumed hereunder, as the case may be, is not consummated on the TCEH Effective Date, as a result of the provisions of Section 2.2(b) or otherwise, then the Parties shall use commercially reasonable efforts to effect
such transfer, assignment or assumption as promptly following the TCEH Effective Date as shall be reasonably practicable. The member of the Company Group retaining such Acquired TCEH Asset or such Assumed Liability, as the case may be, shall
thereafter hold such Acquired TCEH Asset or Assumed Liability, as the case may be, for the use and benefit of the member of the SpinCo Group entitled thereto (at the expense of the member of the SpinCo Group entitled thereto) until such Acquired
TCEH Asset or Assumed Liability is transferred and conveyed to, and assumed by, or until such time as the Company, in good faith, concludes that it is unable, using commercially reasonable efforts, to obtain or cause to be obtained, any consent,
approval or release required to transfer such Acquired TCEH Asset or Assumed Liability to, a member of the SpinCo Group, and SpinCo shall, or shall cause the applicable member of the SpinCo Group to, pay or reimburse the Party retaining such
Acquired TCEH Asset or Assumed Liability for all amounts reasonably paid or incurred in connection with the retention of such Acquired TCEH Asset or Assumed Liability. The Parties agree that, as between the Parties, as of the TCEH Effective
Date, the applicable member of the SpinCo Group shall be deemed to have acquired complete and sole beneficial ownership over all of the Acquired TCEH Assets, together with all rights, powers and privileges incident thereto, and shall be deemed to
have assumed in accordance with the terms of this Agreement all of the Assumed Liabilities, and all duties, obligations and responsibilities incident thereto, which such member is entitled to acquire or required to assume pursuant to the terms of
this Agreement. 
 (d) With respect to any Acquired TCEH Assets or Assumed Liabilities described in Section 2.2(c),
each of the Company and SpinCo shall, and shall cause the members of its respective Group to, (i) treat for all income Tax purposes and for all purposes of the Tax Matters Agreement, (A) any Acquired TCEH Asset retained by the Company Group as
having been transferred to and owned by the member of the SpinCo Group entitled to such Acquired TCEH Asset not later than the TCEH Effective Date and (B) any Assumed Liability retained by the Company Group as a liability having been assumed and
owned by the member of the SpinCo Group intended to be subject to such Assumed Liabilities not later than the TCEH Effective Date 

  
 8 

 
and (ii) neither report nor take any income Tax position (on a Tax Return or otherwise) inconsistent with such treatment (unless required by a change in applicable Tax Law or good faith
resolution of a dispute with a Governmental Entity relating to income Taxes). 
 (e) If and when any violation of Law or
other impediment with respect to such retained Acquired TCEH Asset or Assumed Liabilities has been resolved, the transfer or assignment of the applicable Acquired TCEH Asset or the assumption of the applicable Assumed Liability, as the case may be,
shall be effected in accordance with the terms of this Agreement and the applicable Assignment and Assumption Agreement. 

(f) Any member of the Company Group retaining an Acquired TCEH Asset or Assumed Liability due to the deferral of the transfer
or assignment of such Acquired TCEH Asset or the deferral of the assumption of such Assumed Liability, as the case may be, shall not, in connection with such retention, be obligated, unless the Parties have executed documentation providing for such
asset or liability to be retained by such member of the Company Group pursuant to Section 2.2(b), to expend any money whatsoever unless the necessary funds are advanced (or otherwise made available) by SpinCo or the member of the SpinCo Group
entitled to the Acquired TCEH Asset or Assumed Liability. 
 Section 2.3 Responsibility for Assumed Liabilities Retained by the
Company. If the Company or SpinCo is unable to obtain, or to cause to be obtained, any consent, approval, amendment or release required to transfer an Assumed Liability to a member or members of the SpinCo Group, then the applicable member of
the Company Group shall continue to retain such Assumed Liability and, the applicable member of the SpinCo Group shall, as agent or subcontractor for such member of the Company Group, as the case may be, pay, perform and discharge fully all the
obligations or other Liabilities of such member of the Company Group that constitute or are caused by such Assumed Liabilities, as the case may be, thereunder from and after the Contribution Effective Time. From and after the Contribution
Effective Time, OpCo shall indemnify each Company Indemnified Party, and hold each of them harmless, against any Liabilities arising from any such retained Assumed Liability; provided that OpCo shall have no obligation to indemnify any
Company Indemnified Party that has engaged in any fraud, willful misconduct or knowing and intentional violation of Law, in each case in connection therewith. The Company shall cause each member of the Company Group without further consideration, to
pay and remit, or cause to be paid or remitted, to the applicable member of the SpinCo Group, promptly all money, rights and other consideration received by it or any member of the Company Group in respect of such performance under any agreement,
lease, license or other obligations or Liabilities under any Assumed Liability retained by any member of the Company Group; provided that the Company shall be entitled to offset any amounts owed by the SpinCo Group to any member of the
Company Group hereunder. If and when any such consent, substitution, approval, amendment or release shall be obtained, or the obligations under any agreement, lease, license or other obligations or Liabilities under any Assumed Liability retained by
any member of the Company Group shall otherwise become assignable or able to be novated, the applicable member of the Company Group shall promptly assign, or cause to be assigned, all its obligations and other Liabilities thereunder or any
obligations of any member of the Company Group to the applicable member of the SpinCo Group without payment of further consideration, and the applicable member of the SpinCo Group shall, without the payment of any further consideration, assume such
obligations or other Liabilities in accordance with the terms of this Agreement and the applicable Assignment and Assumption Agreement.

received, or is in possession of, certain non-public, confidential, or proprietary Information (including trade secrets) of the other Party or its respective Group (the “Confidential Information”). Each Party agrees that it
will not, that it will cause its Affiliates not to, and that it will use commercially reasonable efforts to cause each of its and their respective Representatives not to, for a period of five (5) years after the TCEH Effective Date, directly or
indirectly, use Confidential Information of the other Party or its respective Group for its competitive, commercial or proprietary advantage, or disclose, divulge or publish, whether in written or unwritten form or through any medium, such
Confidential Information publicly or to any Person or group of Persons for any reason or purpose whatsoever, except: (i) to authorized Representatives of such Party as reasonably necessary in the course of performing such Party’s
obligations, or enforcing such Party’s rights, under this Agreement or the other Transaction Agreements and (ii) to the extent required to be disclosed by order of a Governmental Entity, or by subpoena, summons or legal process, or by Law,
provided that, to the extent permitted by Law, the disclosing Party shall provide prompt notice of such disclosure to the applicable other Party, so that such Party whose Confidential Information is required to be disclosed may seek to obtain an
order or other reliable assurance that confidential treatment will be accorded to designated portions of such Confidential Information, and the disclosing Party shall reasonably cooperate with the other Party in connection with such other
Party’s efforts to obtain confidential treatment or similar reliable assurances that the relevant Confidential Information will remain confidential. For purposes of this Section 3.5, such Confidential Information shall not include any
Confidential Information that (a) was or becomes generally available to the public other than as a result of a disclosure by such Person (or its Affiliates or Representatives) in violation of this Agreement, (b) becomes available to such Person or
any of such Person’s Affiliates or Representatives after the date hereof from a source other than the other Party hereto or its respective Group or such Group’s Representatives, provided that such source is not known by such Person to be
subject to an obligation of confidentiality (whether by agreement or otherwise) to the other Party with respect to the Information or (c) was independently developed by such Person (or its Affiliates) after the date hereof without reference to,
incorporation of, or other use of any Confidential Information. The limitations in this Section 3.5 are in addition to, and not in lieu of, any other restrictions by which a Party may be bound (whether by contract or
otherwise). 
 Section 3.6 Other Agreements Providing for Exchange of Information.

(a) Any Party that receives, pursuant to a request for Information in accordance with this Article III, Information that
is not relevant to its request shall promptly either destroy such Information or return it to the providing Party, at the option of the providing Party, and if the receiving Party elects to destroy such Information, then the receiving party shall
promptly deliver written confirmation (including by email) of the destruction of such Information to the providing Party. 

(b) When any Information provided by one Group to the other is no longer needed for the purposes contemplated by this Agreement
or any other Transaction Agreement or is no longer required to be retained by applicable Law, the receiving Party will promptly, after request of the providing Party, at the receiving Party’s option (and expense), either return to the providing

  
 11 

 
Party all Information in a tangible form (including all copies thereof and all notes, extracts or summaries based thereon) or destroy such Information (and such copies thereof and such notes,
extracts or summaries based thereon); provided that if the receiving Party elects to destroy such Information, then the receiving Party shall promptly deliver written confirmation (including by email) of the destruction of such Information to
the providing Party; and provided, further, that the receiving Party shall not be deemed to have retained or failed to return or destroy any Confidential Information stored in digital format that is deleted from local hard drives so long as
no attempt is made to recover such Confidential Information from servers or back-up sources, provided that any such retained Confidential Information shall remain subject to the terms hereof in all respects. 

(c) Nothing in this Section 3.6 shall require any Receiving Party to destroy or return any Information that the
Receiving Party would routinely retain pursuant to its record retention policies aimed at legal, corporate governance or regulatory compliance or that the Receiving Party is required to retain under any applicable Law or regulation or the terms of
the Tax Matters Agreement or any other Transaction Agreement; provided that any such retained Confidential Information shall remain subject to the terms hereof in all respects for so long as such Confidential Information is so retained. 

Section 3.7 Production of Witnesses; Records; Cooperation. 

(a) After the TCEH Effective Date, except in the case of an adversarial Action by one Party against another Party, each Party
shall use its commercially reasonable efforts to make available to each other Party, upon written request, the former, current and future directors, officers, employees, other personnel and agents of the members of its respective Group as witnesses
and any books, records or other documents within its control or which it otherwise has the ability to make available, to the extent that any such person (giving consideration to business demands of such directors, officers, employees, other
personnel and agents) or books, records or other documents may reasonably be required in connection with any Action in which the requesting Party may from time to time be involved, regardless of whether such Action is a matter with respect to which
indemnification may be sought hereunder; provided, that no such access shall unreasonably interfere with the ongoing operations of such Party and its Subsidiaries; provided, further, that no Party shall be required to make
available to the requesting Party any such persons or materials if doing so could be commercially detrimental, violate any Law or agreement, or waive any attorney-client privilege held by such Party provided, further, that, as
applicable, the Party making such assertion shall, to the extent permitted by applicable Law, provide notice to the receiving party that any Information is being withheld pursuant to this proviso and the Parties shall use their respective
commercially reasonable efforts to find a mutually agreeable solution to any such commercial, legal and/or privilege concerns, including, if applicable, by providing any privileged Information pursuant to a joint defense agreement to be mutually
agreed and executed between the applicable Parties. The requesting Party shall bear all reasonable out-of-pocket costs and expenses in connection therewith. 

(b) For the avoidance of doubt, the provisions of this Section 3.7 are in furtherance of the provisions of Section
3.1 and shall not be deemed to in any way limit or otherwise modify the Parties’ rights and obligations under Section 3.1.

 13 

 ARTICLE V 

RELEASES AND INDEMNIFICATION 

Section 5.1 Termination of Guarantees. The Parties acknowledge and agree that the obligations of the Company Group under or with
respect to the EFH/TCEH Guarantees shall be terminated and extinguished as of the Contribution Effective Time pursuant to the Plan of Reorganization. 

Section 5.2 General Indemnification by OpCo. Subject to the provisions and limitations of this Article V, from and after the
Contribution Effective Time, OpCo shall indemnify, defend and hold harmless each Person that after the Contribution Effective Time is a member of the Company Group (including all Affiliates of the Company) and each of their respective
Representatives and, as applicable, each of the heirs, executors, successors and assigns of any of the foregoing (collectively, the “Company Indemnified Parties”), from and against: 

(a) any Assumed Liability, including the failure of any member of the SpinCo Group or any other Person to pay, perform or
otherwise promptly discharge any Assumed Liability in accordance with its terms, whether prior to, at or after the Contribution Effective Time; 

(b) any TCEH Company Liability, including the failure of any member of the SpinCo Group or any other Person to pay, perform or
otherwise promptly discharge any TCEH Company Liability in accordance with its terms, whether prior to, at or after the Contribution Effective Time; and 

(c) any Liability arising from any breach by any member of the SpinCo Group of any covenant or other agreement (other than any
representation or warranty) set forth in this Agreement or in any Assignment and Assumption Agreement, subject to any limitations of liability provisions and other provisions applicable to any such breach set forth herein or therein. 

Section 5.3 General Indemnification by the Company. Subject to the provisions and limitations of this Article V, from and after
the Contribution Effective Time, the Company shall indemnify, defend and hold harmless each Person that after the Contribution Effective Time is a member of the SpinCo Group (including all Affiliates of SpinCo) and each of their respective
Representatives and, as applicable, each of the heirs, executors, successors and assigns of any of the foregoing, from and against: 

(a) any Excluded Liability, including the failure of any member of the Company Group or any other Person to pay, perform or
otherwise promptly discharge any Excluded Liability in accordance with their respective terms, whether prior to, at or after the Contribution Effective Time; and 

(b) any Liability arising from any breach by any member of the Company Group of any covenant or other agreement (other than any
representation or warranty) set forth in this Agreement or in any Assignment and Assumption Agreement, subject to any limitations of liability provisions and other provisions applicable to any such breach set forth herein or therein. 

Section 5.4 Tax Indemnification. Notwithstanding anything in Article V to the contrary, indemnification for Taxes and for other
matters subject to the Tax Matters Agreement is governed solely by the terms, provisions and procedures of the Tax Matters Agreement and not by this Article V. 

Section 5.5 Contribution. If the indemnification provided for in this Article V shall, for any reason, be unavailable or
insufficient to hold harmless any Indemnified Party hereunder in respect of any Liability, then each Indemnifying Party shall, in lieu of indemnifying such Indemnified Party, 

  
 14 

 
contribute to the amount paid or payable by such Indemnified Party as a result of such Liability, in such proportion as shall be sufficient to place the Indemnified Party in the same position as
if such Indemnified Party were indemnified hereunder, the Parties intending that their respective contributions hereunder be as close as possible to the indemnification under Section 5.2 and Section 5.3, as the case may be. If the
contribution provided for in the previous sentence shall, for any reason, be unavailable or insufficient to put any Indemnified Party in the same position as if it were indemnified under Section 5.2 or Section 5.3, as the case may be,
then the Indemnifying Party shall contribute to the amount paid or payable by such Indemnified Party as a result of such Liability, in such proportion as shall be appropriate to reflect the relative benefits received by and the relative fault of the
indemnifying Party on the one hand and the Indemnified Party on the other hand with respect to the matter giving rise to the Liability. 

Section 5.6 Indemnification Obligations Net of Insurance Proceeds and Other Amounts. Any Liability subject to indemnification or
contribution pursuant to this Article V will be (a) net of Insurance Proceeds that are actually received by the Indemnified Party, (b) decreased by any actual recoveries from third parties pursuant to indemnification or otherwise with respect
thereto, (c) decreased by any Tax Benefit actually recovered, and (d) increased by any Tax Cost actually incurred as a result of the receipt of (or entitlement to) such indemnity payment, as applicable. Accordingly, the amount which any Party (an
“Indemnifying Party”) is required to pay to any Person entitled to indemnification under this Article V (an “Indemnified Party”) will be reduced by any such Insurance Proceeds and/or recoveries actually
received from third parties and/or Tax Benefits actually recovered, and increased by Tax Costs actually incurred, in each case, by or on behalf of the Indemnified Party in respect of the related Liability, as applicable. If an Indemnified Party
receives a payment (an “Indemnity Payment”) required by this Agreement from an Indemnifying Party in respect of any Liability and subsequently receives Insurance Proceeds or any other recovery from a third party (including any Tax
Benefit actually recovered), then the Indemnified Party will pay to the Indemnifying Party an amount equal to the lesser of (x) the amount of such Insurance Proceeds or the amount actually received from the third party (including any Tax Benefit
actually recovered) and (y) the Indemnity Payment previously received. If an Indemnified Party receives an Indemnity Payment from an Indemnifying Party in respect of any Liability and subsequently incurs Tax Costs associated by that Indemnity
Payment, then the Indemnifying Party will pay to the Indemnified Party an amount equal to those Tax Costs promptly after receipt of a reasonably detailed statement of those Tax Costs given by the Indemnified Party to the Indemnifying Party within a
reasonable period of time (not to exceed six months) after the Tax Cost is actually incurred. In the case of Tax Benefits, “actually recovered” means an Indemnified Party actually realizes a Refund or a decrease in Taxes reported on a
filed Tax Return (in or with respect to a taxable year that ends on or before December 31, 2021) in connection with the incurrence or the payment by the Indemnified Party of such fees or costs or indemnifiable amounts determined using a “with
and without” methodology (treating any deductions attributable to such fees or costs or indemnifiable amounts as the last items claimed for any taxable year, including after the utilization of any available net operating loss carryovers). In
the case of Tax Costs, “actually incurred” means an Indemnified Party actually realizes a Tax Cost reported on a filed Tax Return (in or with respect to a taxable year that ends on or before December 31, 2021) in connection with the
receipt of (or entitlement to) an Indemnity Payment determined using a “with and without” methodology (treating any receipt of (or entitlement to) such Indemnity Payment as the last items claimed for any taxable year, including after the
utilization of any available net operating loss carryovers). For the avoidance of doubt, for purposes of determining the amount “actually recovered” (for purposes of Tax Benefits) or “actually incurred” (for purposes of Tax
Costs), a netting approach shall be taken for determining any increase or decrease, as the case may be, of taxable income or loss, net operating losses, deductions or other Tax attributes. 

Section 5.7 Procedures for Indemnification of Third Party Claims. 

(a) If an Indemnified Party receives written notice that a Person (including any Governmental Entity) that is not a member of
the Company Group or the SpinCo Group, or any Affiliate thereof, has asserted any claim or commenced any Action (any such claim or Action, a 

  
 15 

 
“Third Party Claim”) that may give rise to an Indemnifying Party’s obligation to indemnify pursuant to Section 5.2 or Section 5.3, as the case may be,
then the Indemnified Party shall provide the Indemnifying Party written notice thereof as promptly as practicable (and no later than fifteen (15) Business Days, or sooner, if the nature of the Third Party Claim so requires) after becoming aware of
the Third Party Claim. Such notice shall describe the Third Party Claim in reasonable detail and include copies of all notices and documents (including court papers) received by the Indemnified Party relating to the Third Party Claim.
Notwithstanding the foregoing, the failure of an Indemnified Party to provide notice in accordance with this Section 5.7(a) shall not relieve an Indemnifying Party of its indemnification obligations under this Agreement, except to the
extent the Indemnifying Party is actually prejudiced by the Indemnified Party’s failure to provide notice in accordance with this Section 5.7(a). 

(b) Subject to this Section 5.7(b) and Section 5.7(c), an Indemnifying Party may elect to control the defense of
(and seek to settle or compromise), at its own expense and with its own counsel, any Third Party Claim if the Indemnifying Party irrevocably and unconditionally acknowledges its obligation to indemnify the Indemnified Party in respect of such Third
Party Claim in accordance with and subject to the terms hereof. Within thirty (30) Business Days after the receipt of notice from an Indemnified Party in accordance with Section 5.7(a), the Indemnifying Party shall notify the Indemnified
Party whether the Indemnifying Party will assume responsibility for defending the Third Party Claim. After receiving notice of an Indemnifying Party’s election to assume the defense of a Third Party Claim, an Indemnified Party shall have the
right to employ separate counsel and to participate in (but not control) the defense, compromise, or settlement thereof, but the Indemnified Party shall be responsible for the fees and expenses of its counsel and, in any event, shall cooperate with
the Indemnifying Party in such defense in accordance with Section 5.7(f). If an Indemnifying Party has elected to assume the defense of a Third Party Claim, then such Indemnifying Party shall be solely liable for all fees and expenses
incurred by it in connection with the defense of such Third Party Claim and shall not be entitled to seek any indemnification or reimbursement from the Indemnified Party for any such fees or expenses incurred during the course of its defense of such
Third Party Claim. 
 (c) Notwithstanding Section 5.7(b), if, in the reasonable opinion of counsel to the Indemnified
Party, such Indemnified Party and the Indemnifying Party have actual or potential differing defenses or conflicts of interest between them that make joint representation inappropriate, then the Indemnified Party shall have the right to employ
separate counsel and to participate in (but not control) the defense, compromise, or settlement thereof, and the Indemnifying Party shall bear the reasonable fees and expenses of one (and only one) such counsel for all Indemnified Parties. 

(d) If an Indemnifying Party elects not to assume responsibility for defending a Third Party Claim, or fails to notify an
Indemnified Party of its election within thirty (30) Business Days after the receipt of notice from an Indemnified Party as provided in Section 5.7(b), then the Indemnified Party may defend the Third Party Claim at the cost and expense of the
Indemnifying Party; provided, that the Indemnified Party shall not be permitted to settle or compromise any Third Party Claim without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld,
conditioned or delayed. If the Indemnified Party is conducting the defense against any such Third Party Claim, then the Indemnified Party and its counsel shall keep the Indemnifying Party informed of all developments relating to such Third
Party Claim and provide copies of all relevant correspondence and documents relating thereto. 
 (e) Notwithstanding any
other provision of this Agreement, without the prior written consent of any Indemnified Party, no Indemnifying Party shall consent to the entry of any judgment or enter into any settlement or compromise of any pending or threatened Third Party Claim
for which the Indemnified Party is seeking or may seek indemnity pursuant to this Section 5.7 unless such judgment or settlement is solely for monetary damages (which shall be fully paid 

  
 16 

 
by the Indemnifying Party), does not impose any expense or obligation on the Indemnified Party (other than obligations for which the Indemnified Party is indemnified hereunder and which are fully
paid by the Indemnifying Party), does not involve any finding or determination of wrongdoing or violation of Law by the Indemnified Party and provides for a full, unconditional and irrevocable release of that Indemnified Party and its Affiliates and
Representatives from all liability in connection with the Third Party Claim. 
 (f) Each of the Indemnifying Party and the
Indemnified Party shall use commercially reasonable efforts to make available to the other, upon written request, the former, current and future directors, officers, employees, other personnel and agents of the members of its respective Group as
witnesses and any books, records or other documents within its control or which it otherwise has the reasonable ability to make available, to the extent that any such persons (giving consideration to business demands of such directors, officers,
employees, other personnel and agents) or books, records or other documents may reasonably be required in connection with the defense, settlement or compromise, or the prosecution, evaluation or pursuit of any Third Party Claim, and shall otherwise
reasonably cooperate in such defense, settlement or compromise, or such prosecution, evaluation or pursuit, as the case may be of such Third Party Claim; provided, that no such cooperation shall unreasonably interfere with the ongoing
operations of such Party and its Subsidiaries; provided, further, that no Party shall be required to make available to the requesting Party any such Persons or materials if doing so would reasonably be expected to be materially
commercially detrimental, violate any Law or agreement, or waive any attorney-client privilege held by such Party; provided, further, that, as applicable, the Party asserting such detriment, violation or privilege shall, to the extent
permitted by applicable Law, provide notice to the receiving party that any Information is being withheld pursuant to the foregoing proviso and the Parties shall use their respective commercially reasonable efforts to find a mutually agreeable
solution to any such commercial, legal and/or privilege concerns, including, if applicable, by providing any privileged Information pursuant to a joint defense agreement to be mutually agreed and executed between the applicable Parties. The
Indemnifying Party shall bear all reasonable out-of-pocket costs and expenses in connection therewith. 
 Section 5.8 Additional
Matters. 
 (a) Indemnification or contribution payments in respect of any Liabilities for which an Indemnified Party is
entitled to indemnification or contribution under this Article V shall be paid by the Indemnifying Party to the Indemnified Party as such Liabilities are incurred upon demand by the Indemnified Party, including reasonably satisfactory
documentation setting forth the basis for the amount of such indemnification or contribution payment, including documentation with respect to calculations made and consideration of any Insurance Proceeds and/or recoveries from third parties that
actually reduce the amount of such Liabilities and/or Tax Benefits actually recovered or Tax Costs actually incurred; provided, that no Indemnifying Party shall be entitled to condition, delay or withhold any payment pending claim for, or
receipt of, any Insurance Proceeds and/or recoveries from third parties or actual recovery of any Tax Benefits or actual incurrence of Tax Costs. The indemnity and contribution agreements contained in this Article V shall remain operative and
in full force and effect, regardless of (i) any investigation made by or on behalf of any Indemnified Party and (ii) the knowledge by the Indemnified Party of Liabilities for which it might be entitled to indemnification or contribution hereunder.

 (b) Any claim for indemnification under this Agreement which does not result from a Third Party Claim shall be asserted by
written notice given by the Indemnified Party to the applicable Indemnifying Party. Such Indemnifying Party shall have a period of thirty (30) days after the receipt of such notice within which to respond thereto. If such Indemnifying Party does not
respond within such thirty (30)-day period, such Indemnifying Party shall be deemed to have refused to accept responsibility to make payment. If such Indemnifying Party does not respond 

  
 17 

 
within such thirty (30)-day period or rejects such claim in whole or in part, such Indemnified Party, shall be free to pursue such remedies as may be available to such party as contemplated by
this Agreement without prejudice to its continuing rights to pursue indemnification or contribution hereunder. 
 (c) If
payment is made by or on behalf of any Indemnifying Party to any Indemnified Party in connection with any Third Party Claim, such Indemnifying Party shall be subrogated to and shall stand in the place of such Indemnified Party as to any events or
circumstances in respect of which such Indemnified Party may have any right, defense or claim relating to such Third Party Claim against any claimant or plaintiff asserting such Third Party Claim or against any other Person. Such Indemnified Party
shall cooperate with such Indemnifying Party in a reasonable manner, and at the cost and expense of such Indemnifying Party, in prosecuting any subrogated right, defense or claim. 

Section 5.9 Exclusive Remedy; Limitations of Liability; Mitigation. After the Contribution Effective Time, except for the rights under
Section 7.13, the indemnification and contribution provisions of this Article V shall be the sole and exclusive remedy for the matters set forth herein and in any Assignment and Assumption Agreement and the transactions contemplated
hereby and thereby and no party shall pursue or seek to pursue any other remedy. Neither SpinCo or its Affiliates, on the one hand, nor the Company or its Affiliates, on the other hand, shall be liable to the other for any Liabilities arising under
or relating to this Agreement, any Assignment and Assumption Agreement or the transactions contemplated hereby or thereby that are (i) not direct, actual damages or (ii) special, indirect, consequential, punitive, exemplary, remote, speculative or
similar damages or lost profits (except to the extent such lost profits constitute direct, actual damages) of the other arising in connection with the transactions contemplated hereby (other than such damages described in this clause (ii) payable to
a third party in respect of a Third Party Claim). Any Indemnified Party that becomes aware of a Liability for which it seeks indemnification or contribution under this Article V shall to the extent required by law mitigate such Liability, and
the Indemnifying Party shall not be liable for any such Liability to the extent that it is attributable to the failure of the Indemnified Party to use such commercially reasonable efforts to mitigate to the extent required by law. For the avoidance
of doubt, no provision of this Agreement provides indemnification for a breach, misrepresentation or violation under the Merger Agreement. 

Section 5.10 Survival of Indemnities. The rights and obligations of each of the Company and SpinCo and their respective
Indemnified Parties under this Article V shall survive the sale or other transfer by any Party of any Assets or businesses or the assignment by it of any Liabilities. Each Party hereby agrees that prior to the consummation of any sale or
transfer of all or substantially all of the Assets of such Party, it will require the acquirer of such Assets to assume the obligations of such Party under this Agreement as a condition thereto. 

Section 5.11 No Assumption of Discharged Liabilities; Obligations under Transaction Agreements. For the avoidance of doubt,
nothing herein shall require or be construed to effectuate the assumption, for any period of time, of any Liability or Tax discharged, released or otherwise satisfied (or to be discharged, released or otherwise satisfied on the EFH Effective Date)
pursuant to the Plan of Reorganization. Additionally, for the avoidance of doubt, nothing herein shall require or be construed to effectuate the assumption, for any period of time or at all, of any obligations of any Person, or otherwise affect in
any way the rights or obligations of any of the Parties or their respective Groups, under the Plan of Reorganization, the Tax Matters Agreement, the Transition Services Agreement, the Split Participant Agreement, the Merger Agreement or any other
Transaction Agreement.

any obligations thereunder, shall survive the Distribution Effective Time and shall remain in full force and effect in accordance with their terms. 

Section 7.2 Termination, Wind-Down and Distribution of EFH Non-Qualified Benefit Plans and EFH Split Dollar Life Insurance

Reorganization, the Parties acknowledge and agree that (a) the Company shall (or cause the applicable third party service provider to) provide SpinCo with, and accept all reasonable comments of SpinCo to (i) drafts of all notices and other written

to such participants and (ii) any estimated calculations of payouts and distributions to such participants promptly upon receipt of such calculations from the third party administrator of such EFH Non-Qualified Benefit Plans or the EFH Split Dollar
Life Insurance Plan, as applicable, but in each case, no later than fifteen (15) Business Days prior to the making of any such payments or distributions with respect thereto and (b) SpinCo shall review, comment upon and approve as soon after receipt
as is administratively practicable (i) all such notices and other written correspondence with participants in such EFH Non-Qualified Benefit Plans and the EFH Split Dollar Life Insurance Plan and (ii) any such estimated calculations of payouts and
distributions to such participants, in each case from such third parties as are assisting with such terminations, wind-downs and distributions. 

Section 7.3 Regulatory Matters. In connection with obtaining any required approval by the Public Utility Commission of Texas (the
“PUCT”) with respect to the transactions contemplated by the Merger Agreement or any other transaction constituting a direct or indirect change of control of Oncor Electric Delivery Company LLC that requires the approval of the PUCT
(in each case, the “PUCT Filing”), the Company shall use its reasonable best efforts to cause, including by exercising its rights to consent and vote (if any) under the Oncor Agreements as an indirect equity owner of Oncor, Oncor
Electric Delivery Company LLC to request from the PUCT, as part of the PUCT Filing, an order stating that none of TCEH, SpinCo, or any subsidiaries or Affiliates of SpinCo will, from and after the TCEH Effective Date, be subject to any obligation
set forth in the Final Order on Rehearing issued in PUCT Docket No. 34077 on April 24, 2008. The Company’s obligations under this Section 7.3 including using its reasonable best efforts, shall not include any obligation to (A) pay
any amounts to the Oncor Entities (as defined in the Merger Agreement) or any other Person or incur any liabilities or other obligation, (B) execute or enter into or perform any new agreement (other than an agreement contemplated hereby or in the
Plan of Reorganization or that confirms or makes effective its obligations hereunder), or (C) breach any Law or commence any Action against any Person, including any of the Oncor Entities or their respective officers and managers. 

Section 7.4 D&O Insurance. 

(a) During the period beginning on the date hereof and ending on the EFH Effective Date, the Company agrees to and to cause its
Subsidiaries to maintain, as in effect immediately prior to the TCEH Effective Date (i) the Company’s and its Subsidiaries’ directors’, managers’ 

  
 19 

 
and officers’ insurance policies, and (ii) the Company’s fiduciary liability insurance policies ((i) and (ii), collectively, the “EFH D&O Policies”), in each case,
with terms, conditions, retentions and limits of liability that are no less advantageous than the coverage provided under the Company’s and its Subsidiaries’ policies as of immediately prior to the TCEH Effective Date with respect to any
actual or alleged error, misstatement, misleading statement, act, omission, neglect, breach of duty or any matter claimed against a current or former director, officer or other Representative of TCEH, the TCEH Companies, the Company Group or the
SpinCo Group or any of their respective Subsidiaries (collectively, the “Pre-Spin Group”) by reason of him or her serving in such capacity (“Wrongful Acts”) that existed or occurred on or prior to the TCEH Effective
Date (including in connection with this Agreement and the transactions or actions contemplated by this Agreement). 
 (b) The
Company agrees that, on or before the EFH Effective Date or any other event constituting a change in control as described in Section IX(C)(2) of the EFH D&O Policies (a “Company Change in Control”), it will obtain and fully pay
the premium for a run-off of the EFH D&O Policies for the benefit of each member of the Pre-Spin Group and their respective current and former directors, officers and other Representatives, in each case for a claims reporting or discovery period
of at least six (6) years from and after the EFH Effective Date (or the effective date of such other Company Change in Control, as applicable) with respect to any claim arising from actual or alleged Wrongful Acts on or prior to the EFH
Effective Date (it being understood that, with respect to any claim arising from actual or alleged Wrongful Acts of such Persons in their capacity as a current or former director or officer or other Representative of any TCEH Company or the SpinCo
Group, such period shall be limited to the period on or prior to the TCEH Effective Date), from insurance carriers with the same or better credit rating as the insurance carrier(s) for the EFH D&O Policies with terms, conditions, retentions and
limits of liability that are no less advantageous than the coverage provided for members of the Pre-Spin Group and their respective current and former directors, officers and other Representatives under the EFH D&O Policies with respect to any
actual or alleged Wrongful Act that existed or occurred on or prior to the EFH Effective Date (the “Run-Off Coverage”). 

(c) If the Company, after its good faith efforts, is unable to obtain such Run-Off Coverage as of the EFH Effective Date, then
the Company shall use its reasonable best efforts to purchase insurance comparable to the EFH D&O Policies for such six-year period with terms, conditions, retentions and limits of liability that are at least as favorable as provided in the EFH
D&O Policies; provided, however, that in no event shall the Company be required to expend for such policies pursuant to this sentence an annual premium amount in excess of 200% of the annual premiums paid by the Company for such
insurance as of immediately prior to the TCEH Effective Date; and provided, further, that if the annual premiums of such insurance coverage exceed such amount, the Company shall obtain a policy with the greatest coverage available for
a cost not exceeding such amount. 
 (d) If the Effective Time under the Merger Agreement occurs and the Company complies
with its obligation under Section 6.8(b) of the Merger Agreement (as such obligations are set forth in the Merger Agreement as of the date hereof and without giving effect to any subsequent amendment thereof) and obtains the “D&O
Insurance” (as defined in the Merger Agreement), then the Company shall be deemed to have satisfied its obligations under Section 7.4(b) and (c) hereof; provided, however that this Section 7.4(d) shall have no
effect and be null and void if the Merger Agreement is terminated or the Effective Time under the Merger Agreement otherwise never occurs. 

(e) Additionally, the Company agrees not to seek or, subject to Section 7.4(c), agree to any changes or amendments to
the EFH D&O Policies or the Run-Off Coverage that have or would reasonably be expected to have the effect of reducing or limiting coverage available to any member of the Pre-Spin Group or any of their respective current and former directors,
officers and other Representatives.

  
 20 

 (f) Within ten (10) Business Days of the written request of SpinCo, the Company
shall provide SpinCo copies of all EFH D&O Policies or Run-Off Coverage policies. 
 (g) The Parties agree that the
provisions of this Section 7.4 are for the benefit of each member of the Pre-Spin Group and their respective current and former directors, officers and other Representatives (collectively, the “Beneficiaries”). The
provisions of this Section 7.4 shall be enforceable by each of the Beneficiaries as if such Person were a party to this Agreement. 

Section 7.5 Amendment. No provision of this Agreement shall be terminated, amended, modified or supplemented by any Party, unless such
termination, amendment, supplement or modification is in writing and signed by each of the Parties.

 (a) Any term or provision of this Agreement may be waived, or the time for its performance may be extended, by the Party
or the Parties entitled to the benefit thereof. Any such waiver shall be validly and sufficiently given for the purposes of this Agreement if, as to any Party, it is in writing signed by an authorized representative of such Party. 

(b) Waiver by any Party of any default by the other Party of any provision of this Agreement or any Assignment and Assumption
Agreement shall not be construed to be a waiver by the waiving party of any subsequent or other default, nor shall it in any way affect the validity of this Agreement or any Party or prejudice the rights of the other Party or Parties thereafter to
enforce each and every such provision. No failure or delay by any Party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise
thereof or the exercise of any other right, power or privilege. 
 Section 7.7 Third Party Beneficiaries. Except (i) for the
indemnification rights under this Agreement of any Indemnified Party in their respective capacities as such, (ii) the Beneficiaries pursuant to Section 7.4 and (iii) as specifically provided in any Assignment and Assumption Agreement, the
provisions of this Agreement and each Assignment and Assumption Agreement are solely for the benefit of the parties hereto and thereto and their respective successors and permitted assigns and are not intended to confer upon any Person, except the
parties hereto and thereto and their respective successors and permitted assigns, any rights or remedies hereunder and there are no third party beneficiaries of this Agreement or any Assignment and Assumption Agreement; and neither this Agreement
nor any Assignment and Assumption Agreement shall provide any third party with any remedy, claim, liability, reimbursement, claim of action or other right in excess of those existing without reference to this Agreement or any Assignment and
Assumption Agreement.

electronic means), each such counterpart being deemed to be an original instrument, and all such counterparts taken together constituting one and the same agreement.

THE COMPANY GROUP MAKES ANY REPRESENTATIONS OR WARRANTIES, AND EACH HEREBY DISCLAIMS ANY OTHER REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED, INCLUDING AS TO THE ACCURACY OR COMPLETENESS OF ANY OTHER INFORMATION WITH RESPECT TO, OR IN CONNECTION

Agreement; and (d) they knowingly waive any right to rescind or avoid this Agreement based upon presently existing facts, known or unknown.

Liabilities and all costs, fees and expenses under the Letters of Credit identified on Annex A attached hereto (the “Split Letters of Credit”) (including any draws on the Split Letters of Credit in respect of the Company
Policy Liabilities and the costs of maintaining such Split Letters of Credit allocable to the Company Policy Liabilities) arising out of or resulting from the Company Policy Liabilities are Excluded Liabilities for all purposes hereunder, and (ii)

 Assignment and Assumption
Agreements 
 (TCEH Assets) 

ASSIGNMENT AND ASSUMPTION AGREEMENT 
  

 
 This Assignment and Assumption
Agreement (this “Agreement”) is effective as of [●], 2016, by and among Energy Future Holdings Corp., a Texas corporation (the “Company”), Texas Competitive Electric Holdings Company LLC, a Delaware limited
liability company (“TCEH”), and TEX Energy LLC, a Delaware limited liability company (“SpinCo”). 

WHEREAS, TCEH is an indirect wholly owned subsidiary of the Company and SpinCo is a direct wholly owned subsidiary of TCEH; 

WHEREAS, the Company owns (i) the Acquired TCEH Assets (as defined in the Separation Agreement referred to below) (the “EFH
Contributed Assets”) and (ii) directly or indirectly, all of the outstanding equity interests of the entities listed on Schedule B hereto (the “EFH Contributed Subsidiaries”); 

WHEREAS, TCEH owns (i) the assets identified on Schedule A hereto (the “TCEH Contributed Assets,” and together
with the EFH Contributed Assets, the “Contributed Assets”) and (ii) directly or indirectly, all of the outstanding equity interests of the entities listed on Schedule B hereto (the “TCEH Contributed
Subsidiaries”); and 
 WHEREAS, as contemplated by that certain Separation Agreement, dated as of the date hereof, by and between
the Company, SpinCo, and TEX Operations Company LLC, a Delaware limited liability company and indirect wholly owned subsidiary of TCEH (as amended, the “Separation Agreement”), the Company desires to contribute, convey, transfer and
assign the EFH Contributed Assets and the EFH Contributed Subsidiaries, and TCEH desires to contribute, convey, transfer and assign the TCEH Contributed Assets and the TCEH Contributed Subsidiaries, to SpinCo. 

NOW THEREFORE, in consideration of the mutual covenants set forth herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows: 
 1. Capitalized Terms. Capitalized terms
used herein and not defined herein have the meanings assigned to them in the Separation Agreement. 
 2. EFH Contribution. The
Company hereby contributes, conveys, transfers and assigns the EFH Contributed Assets and the EFH Contributed Subsidiaries to SpinCo, and SpinCo hereby accepts such contribution, conveyance, transfer and assignment (the “EFH
Contribution”). SpinCo hereby assumes and agrees to pay, discharge, perform or otherwise satisfy as and when due all liabilities and obligations of any kind and nature, in each case, arising out of facts, circumstances, events or
conditions in existence before, on or after the date hereof of, under, related to, resulting from, or arising out of or in connection with, as applicable, the EFH Contributed Subsidiaries, the EFH Contributed Assets and all Assumed Liabilities (as
defined in the Separation Agreement) (the “EFH Assumed Liabilities”). 

 3. TCEH Contribution. TCEH hereby contributes, conveys, transfers and assigns the
TCEH Contributed Assets and TCEH Contributed Subsidiaries to SpinCo, and SpinCo hereby accepts such contribution, conveyance, transfer and assignment (the “TCEH Contribution,” and together with the EFH Contribution, the
“Contributions”). SpinCo hereby assumes and agrees to pay, discharge, perform or otherwise satisfy all liabilities and obligations of any kind and nature arising out of or otherwise relating to the TCEH Contributed Assets and
any other liabilities identified on Schedule C hereto (the “TCEH Assumed Liabilities,” and together with the EFH Assumed Liabilities, the “Assumed Liabilities”). 

4. Further Assurances. In furtherance of the transactions described herein, the parties hereto shall, and shall cause their applicable
subsidiaries to, execute such additional bills of sale, quitclaim deeds, stock or equity powers, certificates of title, assignments of contracts and other instruments of transfer, conveyance and assignment and other documents reasonably necessary to
evidence the transfer, conveyance and assignment of the Contributed Assets to SpinCo and the valid and effective assumption of the Assumed Liabilities by SpinCo, including any which are not transferred on the date hereof as a result of Section
2.2(b) of the Separation Agreement or for any other reason. 
 5. Tax Treatment. For federal income tax purposes, at the
time of the Contributions, each of TCEH and SpinCo is an entity that is disregarded as separate from the Company, and accordingly, the Contributions will have no federal income tax effect. For Texas sales and use tax purposes, the Contributions will
be treated as (i) a transfer of intangible assets not subject to Texas sales and use tax, and/or (ii) a transfer of assets constituting a separate division, branch, or identifiable segment of a business that is exempt from Texas sales and use tax as
an occasional sale. 
 6. Counterparts. This Agreement may be executed in any number of counterparts (including by electronic
means), each such counterpart being deemed to be an original instrument, and all such counterparts taken together constituting one and the same agreement. 

7. Captions. The captions of the paragraphs herein are inserted for convenience of reference only and shall not be used in
construing the terms and provisions hereof. 
 8. Successors and Assigns. This Agreement shall be binding upon, and shall inure
to the benefit of, the parties hereto and their respective heirs, legal representatives, successors and permitted assigns. 
 9.
Governing Law and Venue; Waiver of Jury Trial.
 (a) THIS AGREEMENT, TOGETHER WITH ANY CLAIM, DISPUTE, REMEDY OR ACTION ARISING FROM
OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR ANY RELIEF OR REMEDIES SOUGHT BY ANY PARTY, AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER, SHALL BE CONSTRUED, PERFORMED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF
THE STATE OF DELAWARE, WITHOUT GIVING EFFECT TO ITS PRINCIPLES OR RULES OF CONFLICT OF LAWS TO THE EXTENT SUCH PRINCIPLES OR RULES WOULD REQUIRE OR PERMIT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION. Each of the parties hereto (i)
submits to the exclusive jurisdiction of the Bankruptcy Court; provided that if the Bankruptcy Court declines to accept jurisdiction over a particular Action, then the Chancery Court of the State of Delaware, and if the Chancery Court of the State
of Delaware declines jurisdiction, then any state or federal court sitting in Delaware, in any Action arising out of or relating to this Agreement, (ii) agrees that all claims in respect of such Action may be heard and determined in any such court
and (iii) agrees not to bring any Action arising out of or relating to this Agreement (whether on the basis of a claim sounding in contract, equity, tort or otherwise) in any other court. Each of the parties agrees that a final judgment (subject to
any 

 
appeals therefrom) in any such Action shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. Each of the parties hereby
irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any Action arising out of or relating to this Agreement or the
transactions contemplated hereby in any Delaware or federal court in accordance with the provisions of this Section. Each of the parties hereby irrevocably waives, to the fullest extent permitted by Law, the defense of an inconvenient forum to the
maintenance of such Action in any such court. Each of the parties hereby irrevocably and unconditionally consents to service of process in the manner provided for notices in the Separation Agreement. Nothing in this Agreement will affect the right
of any party to serve process in any other manner permitted by Law. 
 (b) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH
MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY
OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (W) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT
SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (X) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (Y) EACH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (Z) EACH PARTY HAS BEEN
INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION. 
 10. Limitations of
Liability. The Liabilities of any party hereto arising out of or relating to this Agreement shall be limited pursuant to and as provided in the Separation Agreement. 

11. No Third Party Beneficiaries. Except for the indemnification rights under the Separation Agreement of any Indemnified Party in
their respective capacities as such, the provisions of this Agreement and the Separation Agreement are solely for the benefit of the parties hereto and thereto and their respective successors and permitted assigns and are not intended to confer upon
any Person, except the parties hereto and thereto and their respective successors and permitted assigns, any rights or remedies hereunder and there are no third party beneficiaries of this Agreement or the Separation Agreement; and neither this
Agreement nor the Separation Agreement shall provide any third party with any remedy, claim, liability, reimbursement, cause of action or other right in excess of those existing without reference to this Agreement or the Separation Agreement. 

12. Assignment. Neither party shall assign its rights or obligations under this Agreement (by operation of law or otherwise) unless,
such party concurrently assigns its rights and obligations under the Separation Agreement to the same assignee of its rights and obligations hereunder.

to OpCo the sponsorship (including the assumption of all assets and liabilities thereto) of each of the Contributed Plans and the Agreement Parties desire to transfer and assign its rights and obligations under each Agreement to which it is a party,
and OpCo desires to accept and assume all such transfers; and 
 WHEREAS, the parties desire to enter into this Agreement to evidence
and effectuate such transfer and assignment, and acceptance and assumption of the Contributed Plans and the Agreements. 
 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: 
 1. Assignment and Assumption of Plans. Effective as of the TCEH Effective
Date, the sponsorship and all obligations relating to the maintenance and administration of each of the Contributed Plans are hereby transferred and assigned from EFH to OpCo, and OpCo hereby accepts such transfer and assignment. By virtue of
such assignment and assumption, OpCo hereby possesses all rights, authority, and responsibility as plan sponsor, employer and a participating employer and fiduciary under each of the Contributed Plans. Effective as of the TCEH Effective Date,
OpCo hereby assumes full responsibility for the liabilities, qualification, administration and compliance with all applicable legal requirements relating to each of the Contributed Plans, including without limitation the provision of all benefits
due or required to be paid under the Contributed Plans (including benefits accrued or which become payable prior to the Effective Date). 

2. Assignment and Assumption of Agreements. Effective as of the TCEH Effective Date, the rights and obligations of the Agreement
Party under each of the applicable Agreements are hereby transferred and assigned from the applicable Agreement Parties to OpCo, and OpCo hereby accepts such transfer and assignment. By virtue of such assignment and assumption, OpCo hereby
possesses all rights and obligations of the applicable Agreement Parties under each of the Agreements. Effective as of the TCEH Effective Date, OpCo hereby assumes full responsibility for the performance of all obligations of the Agreement
Party under each of the applicable Agreements. EFH, the Agreement Party and OpCo shall reasonably cooperate with each other to cause each of the Contributed Plans and Agreements to be amended, as necessary, to reflect the assignment, transfer
and assumption evidenced hereby. To the extent that the transfer, acceptance and assignment of any of the Agreements require the consent of an individual employee, affiliate or third party, as applicable, the parties shall reasonably cooperate
to obtain such consent. 
 3. Plan Administrator. From and after the TCEH Effective Date, the named fiduciary and plan
administrator, as applicable, of each of the Contributed Plans shall be the applicable administrative committee, or other designee, of OpCo, which shall replace the applicable named fiduciary and plan administrator of EFH in such capacity, and shall
have all responsibility and authority necessary or appropriate to administer the Contributed Plans in accordance with their terms. All policies and decisions adopted by the applicable EFH plan administrator prior to the TCEH Effective Date
shall, unless and until changed by the applicable OpCo plan administrator, continue in effect. Without limiting the generality of the foregoing, all funding and investment policies, loan, withdrawal and distribution procedures, procedures for
processing domestic relations orders and qualified medical child support orders, 

 
procedures for processing claims, and any other policies or procedures relating to the administration of any of the Contributed Plans, previously adopted by the applicable EFH plan administrator,
shall remain in full force and effect unless and until changed by the applicable OpCo plan administrator. 
 4. Fidelity Bond; Liability
Insurance. EFH and OpCo shall timely notify the issuer of any fidelity bond or liability insurance policy relating to any Contributed Plan or Agreement of the transfer, assignment and assumption provided for herein, and the parties shall
fully cooperate and take all action necessary to effectuate the transfer, assignment and assumption with respect to such fidelity bonds and insurance policies so as to ensure coverage of OpCo, the applicable OpCo plan administrators and all entities
and individuals involved in the administration of the Contributed Plans and Agreements from and after the TCEH Effective Date. 
 5.
Effect on Employment. It is the intent of the parties, that the transfer of employment of employees from EFH, and certain of its affiliates (other than Oncor Electric Delivery Holdings Company, LLC and its subsidiaries), to OpCo shall be
treated as a transfer of employment and not as a termination of employment for purposes of any of the Contributed Plans. In this connection, each employee shall be treated as if his/her employment has not been terminated as a result of the
transfer from EFH, or an affiliate of EFH, to OpCo, and his/her service, for all purposes under each Contributed Plan and Agreement, shall be treated as continuous without any break in service related to such transfer. Notwithstanding the
foregoing, consistent with the Plan of Reorganization, the Closing of the transactions contemplated in the Plan of Reorganization shall be deemed to constitute a change in control of EFH for purposes of the applicable Contributed Plans. 

6. Employee Communications. OpCo shall be responsible for preparing and distributing summaries of material modifications and other
communication materials to notify employees of the assignment, transfer and assumption evidenced hereby. EFH shall cooperate with OpCo in the preparation of such materials as may be reasonably requested by OpCo. 

7. Reports to Governmental Agencies; Audits. From and after the TCEH Effective Date, OpCo shall be responsible for preparing,
filing and/or distributing all required governmental reports relating to the Contributed Plans including without limitation, Annual Returns/Reports (Form 5500 Series), Summary Annual Reports, Annual Funding Notices, and all filings required under
the Affordable Care Act. EFH shall, or shall cause its affiliates to, cooperate with OpCo, and provide OpCo with all information available to EFH or its affiliates, as OpCo may reasonably request, in connection with the preparation of such
reports. Additionally, in the event of a governmental audit, investigation or inquiry relating to any of the Contributed Plans, EFH and OpCo shall fully cooperate with each other, and EFH shall, or shall cause its affiliates to, provide OpCo
with all information or documentation in EFH’s, or its affiliates’ possession or control as may be reasonably requested by OpCo in connection with any such audit, investigation or inquiry. 

8. Transfer of Records. To the maximum extent allowed under applicable law, EFH shall, or shall cause its affiliates to, transfer
to OpCo all records pertaining to the Contributed Plans and Agreements in EFH’s, or its affiliates, possession or control as soon as reasonably practical following the Effective Date. 

9. No Plan Amendment. Except as expressly provided for herein, nothing in this Agreement shall be construed or deemed to
constitute an amendment to any Contributed Plan, and nothing in this Agreement shall limit, in any way, the right and authority of OpCo to amend each of the Contributed Plans, in whole or in part, from time to time. 

10. No Third Party Beneficiary. Nothing in this Agreement shall create any rights in any person or entity other than the parties
hereto, including without limitation any participant, beneficiary, dependent or other covered person under any Contributed Plan. 

 11. Further Acts. The parties agree to take any and all further action and to execute
any and all further documents as either of them may reasonably determine to be necessary or appropriate to effectuate the transfer, assignment and assumption of the Contributed Plans and the Agreements, and all other matters contemplated in this
Agreement.
 12. Applicable Law. TO THE EXTENT NOT OTHERWISE GOVERNED BY FEDERAL LAWS SUCH AS ERISA AND THE CODE (AS SUCH TERMS
ARE DEFINED IN THE MERGER AGREEMENT) THIS AGREEMENT SHALL BE GOVERNED AND CONSTRUED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS OF THE STATE OF TEXAS. 

13. Binding Effect; Assignment. All of the terms and provisions of this Agreement shall be binding upon and inure to the benefit
of, and be enforceable by the parties hereto and their respective successors and permitted assigns. Neither party shall assign its rights or obligations under this Agreement (by operation of law or otherwise) unless, such party concurrently
assigns its rights and obligations under the Separation Agreement to the same assignee of its rights and obligations hereunder. 
 14.
Invalidity of Provisions. In the event that one or more of the provisions contained in this Agreement shall be invalid, illegal or unenforceable in any respect under any applicable law, the validity, legality or enforceability of the
remaining provisions hereof shall not be affected or impaired thereby. 
 15. Entire Agreement. This Agreement, together with
that certain Separation Agreement, by and among EFH, OpCo and TEX Energy LLC, a Delaware limited liability company, dated as of the date hereof (the “Separation Agreement”), constitutes the whole and entire agreement between the
parties hereto and supersedes any prior agreement, undertaking, declaration, commitment or representation, verbal or oral, with respect to the subject matter hereof. 

16. Limitations of Liability. The liabilities of the parties hereto arising out of or relating to this Agreement shall be limited
pursuant to and as provided in the Separation Agreement. 
 17. Defined Terms. Capitalized terms not defined herein shall be
given the meaning ascribed to them in the Merger Agreement, Plan of Reorganization or Separation Agreement. In the event of a conflict between any such definitions, the definition in the Merger Agreement shall be controlling. 

18. Captions. The captions of the sections and paragraphs of this Agreement are for convenience and reference only and in no way
define, limit or describe the scope or intent of this Agreement. 

 IN WITNESS WHEREOF, the parties have caused this Agreement to be duly executed as of the
Effective Date.
