 This EMPLOYMENT AGREEMENT (the “Agreement”) dated December 31, 2007 is made by and between TXU ENERGY RETAIL COMPANY LLC (the
“Company”), Energy Future Holdings Corp., (the parent entity of the Company, “Holdings”) and James Burke (the “Executive”). 
 WITNESSETH 
 WHEREAS, in connection with the closing on October 10, 2007 of the
transactions contemplated in the Agreement and Plan of Merger (the “Merger Agreement”) among Holdings (formerly TXU Corp.), Texas Energy Future Holdings Limited Partnership and Texas Energy Future Merger Sub Corp. (the
“Closing”), the Company desires to employ Executive and to enter into an agreement embodying the terms of such employment; 
 WHEREAS, Company desires to employ Executive and Executive desires to accept such employment commencing on the Effective Date (as defined herein), in each case on the terms and conditions set forth herein; 
 NOW, THEREFORE, in consideration of the mutual promises, covenants and obligations contained herein, Company and Executive agree as follows: 

1. Term of Employment. Subject to the provisions of Section 7 of this Agreement, this Agreement and Executive’s employment hereunder
shall be effective as of the Closing (the “Effective Date”) and shall continue until the third anniversary of the Effective Date (the “Initial Term”). Subject to the provisions of Section 7 of this Agreement, the Initial
Term shall be extended as follows: (i) this Agreement shall automatically renew for an additional one (1) year period commencing immediately following the last day of the Initial Term and each one (1) year period thereafter (each, a
“Renewal Term”), unless, the Company or Executive provides the other party written notice of non-renewal at least sixty (60) days prior to the end of the applicable term. The period during which Executive is employed by the Company
hereunder is hereinafter referred to as the “Employment Term”. 
 2. Positions. 
 a. During the Employment Term, Executive shall serve as Chief Executive Officer (“CEO”) of the Company. Executive shall also
serve as a member of the board of directors of the Company (the “Board”) as its Chairman without additional compensation. In such position, Executive shall have such duties, authority and responsibilities as shall be determined from time
to time by the Board, which duties, authority and responsibilities are customary for Executive’s position in a business of a similar size, type and nature to that of the Company. Executive shall report to the Board with respect to his
responsibilities to the Company. 
 b. During the Employment Term, Executive will devote Executive’s full business time
and best efforts to the performance of his duties hereunder and will not engage in any other business, profession or occupation for compensation or otherwise which would conflict or interfere with the rendition of such services either directly or
indirectly, without the prior 

 
written consent of the Board; provided, however, that nothing herein shall preclude Executive from serving on the outside board of directors of
one other company and, subject to the prior approval of the Board, which approval shall not be unreasonably withheld, from accepting appointment to or continuing to serve on such additional boards of directors or trustees of any other business,
corporation or charitable organization; provided, further, that, in each case, such activities do not conflict or interfere with the performance of Executive’s duties hereunder or conflict with Section 8. 
 3. Base Salary. During the Employment Term, the Company shall pay Executive a base salary at the annual rate of $600,000, payable in regular
installments in accordance with the Company’s usual payment practices. Executive shall be entitled to such increases, if any, in his base salary as may be determined from time to time in the sole discretion of the Board, in accordance with the
Company’s normal annual review process for executives. Executive’s annual base salary, as in effect from time to time, is hereinafter referred to as the “Base Salary”. 
 4. Annual Bonus. With respect to each full fiscal year during the Employment Term, commencing with the 2008 fiscal year, Executive shall have the
opportunity to earn an annual bonus award (the “Annual Bonus”) of 75% of his Base Salary (“Annual Bonus Target”), as in effect at the beginning of the applicable fiscal year, based upon the achievement of annual performance
targets established by the Board; provided, however, if Executive achieves superior performance targets as established by the Board, then Executive shall be eligible to receive a bonus award constituting 200% of his Base Salary.
Executive shall be entitled to receive a cash bonus with respect to the 2007 fiscal year (the “2007 Award”) as provided in the Additional Payment Agreement dated between the Executive, the Company and Holdings dated October 10, 2007
(the “Additional Payment Agreement”). The 2007 Award and the Annual Bonus, if any, shall be paid to Executive within two and one-half (2.5) months after the end of the applicable fiscal year. 
 5. Stock Compensation; Employee Benefits; Perquisites; Fringe Benefits. 
 a. Upon, or as soon as practicable after the date hereof, Holdings shall grant the Executive an option to purchase 2,450,000 shares of
common stock of Holdings at a price per share of $5.00 (which is intended to equal to be the fair market value of a share) pursuant to Holding’s 2007 Stock Incentive Plan in substantially the form attached hereto as Annex A in accordance with
terms and conditions set forth in the Non-Qualified Stock Option Agreement in substantially the form attached hereto as Annex B. 
 b. During the Employment Term, Executive shall be entitled to participate in the Company’s group health, life, disability and other employee benefit plans as in effect from time to time (collectively “Employee Benefits”), on
a basis which is no less favorable than is provided to other similarly situated executives of the Company, to the extent consistent with applicable law and the terms of the applicable plans and standard perquisites. 
 c. During the Employment Term, Executive shall be entitled to fringe benefits consistent with the practices of the Company, and to the
extent the Company provides similar benefits to other similarly situated Company executives, the Company shall pay on behalf of the Executive, the monthly membership fees of a country club selected by Executive.

 6. Business Expenses. Subject to Company’s standard policies and procedures with respect to
expense reimbursement as applied to its executive employees generally, Company shall reimburse Executive for, or pay on behalf of Executive, reasonable and appropriate expenses incurred by Executive for business related purposes. 
 7. Termination. The Employment Term and Executive’s employment hereunder may be terminated by either the Company or the Executive at any time
and for any reason; provided that, unless otherwise provided herein, either party will be required to give the other party at least sixty (60) days advance written notice of any termination of Executive’s employment. Notwithstanding any
other provision of this Agreement, the provisions of this Section 7 shall exclusively govern Executive’s rights upon termination of employment with the Company and its affiliates. 
 a. By the Company For Cause or By Executive Due to Voluntary Resignation Without Good Reason. (i) The Employment Term and
Executive’s employment hereunder may be terminated by the Company for Cause (as defined below) and shall terminate upon Executive’s voluntary resignation without Good Reason (as defined below). If Executive’s employment is terminated
by the Company for Cause, or if Executive resigns without Good Reason, Executive shall be entitled to receive: 
 (A) within
ten (10) days following the date of termination, accrued, but unpaid Base Salary, earned through the date of termination; 
 (B) accrued, but unpaid Annual Bonus, earned for any previously completed fiscal year, paid in accordance with Section 4 (except to the extent payment is otherwise deferred pursuant to any applicable deferred compensation arrangement
with the Company); 
 (C) reimbursement, within sixty (60) days following submission by Executive to the Company, as
applicable, of appropriate supporting documentation, for any unreimbursed business expenses properly incurred by Executive in accordance with the Company’s policies prior to the date of Executive’s termination; provided claims for such
reimbursement (accompanied by appropriate supporting documentation) are submitted to the Company within ninety (90) days following the date of Executive’s termination of employment; and 
 (D) such Employee Benefits (including stock compensation), if any, as to which Executive may be entitled under the employee benefit plans
of the Company (the amounts described in clauses (A) through (D) hereof being referred to as the “Accrued Rights”). 
 Following
such termination of Executive’s employment by the Company for Cause or voluntary resignation by Executive without Good Reason, except as set forth in this Section 7(a)(i), Executive shall have no further rights to any compensation or any
other benefits under this Agreement. 
 (ii) For purposes of this Agreement, the terms: 
  

 3 

 (A) “Cause” shall mean (i) if, in carrying out his duties to the
Company, the Executive engages in conduct that constitutes (a) a material breach of his fiduciary duty to the Company or its shareholders (including, without limitation, a material breach or attempted breach of the provisions under
Section 8), (b) gross neglect or (c) gross misconduct resulting in material economic harm to the Company, provided that any such conduct described in (a), (b) or (c) is not cured within ten (10) business days after the
Executive receives from the Company written notice thereof, or (ii) Executive’s conviction of , or entry of a plea of guilty or nolo contendere for, a felony or other crime involving moral turpitude. 
 (B) “Good Reason” shall mean (i) a reduction in the Executive’s base salary or the Executive’s annual
incentive compensation opportunity (other than a general reduction in base salary or annual incentive compensation opportunities that affects all salaried employees of the Company equally); (ii) a transfer of the Executive’s primary
workplace by more than thirty-five (35) miles from the current workplace; (iii) a substantial adverse change in the Executive’s duties or responsibilities; (iv) any material breach of this Agreement; or (v) an adverse change
in the Executive’s post-Closing line of reporting to superior officers pursuant to the terms of this Agreement; provided, however, that any isolated, insubstantial and inadvertent failure by the Company that is not in bad faith
and is cured within ten (10) business days after the Executive gives the Company written notice of any such event set forth above, shall not constitute Good Reason. 
 b. Disability or Death. (i) The Employment Term and Executive’s employment hereunder shall terminate upon
Executive’s death and may be terminated by the Company if Executive has a Disability as hereinafter defined. Upon termination of Executive’s employment hereunder for either Disability or death, Executive or Executive’s estate (as the
case may be) shall be entitled to receive: 
 (A) the Accrued Rights; and 
 (B) a pro-rata portion of the Annual Bonus Target, if any, that Executive would have been entitled to receive pursuant to Section 4
hereof for the fiscal year of termination, multiplied by a fraction, the numerator of which is the number of days during which Executive was employed by the Company in the fiscal year of Executive’s termination, and the denominator of which is
365 (the “Pro-Rata Bonus”), with such Pro-Rata Bonus payable to Executive pursuant to Section 4 as if Executive’s employment had not terminated. 
 Following Executive’s termination of employment due to death or Disability, except as set forth in this Section 7(b)(i), Executive shall have no further rights to any compensation or any other benefits under
this Agreement. 
 (ii) “Disability” shall mean Executive’s physical or mental incapacitation and consequent
inability for a period of six consecutive months to perform Executive’s duties; provided, however, in the event the Company temporarily replaces Executive, or transfers Executive’s duties or responsibilities to another individual, on
account of Executive’s mental or physical impairment for a period of time which is covered by the Company’s short term disability plan, Executive’s employment shall not be deemed terminated by the Company and the Executive shall not
be able to resign with Good Reason. Any question 

  

 4 

 
as to the existence of the Disability of Executive as to which Executive and the Company cannot agree shall be determined in writing by a qualified
independent physician mutually acceptable to Executive and the Company. If Executive and the Company cannot agree as to a qualified independent physician, each shall appoint a physician and those two physicians shall select a third who shall make
such determination in writing. The determination of Disability made in writing to the Company and Executive shall be final and conclusive for all purposes of the Agreement and any other agreement with Executive that incorporates this definition of
“Disability”. 
 c. By the Company Without Cause; Resignation by Executive for Good Reason. The Employment
Term and Executive’s employment hereunder may be terminated by the Company without Cause (other than by reason of death or Disability) or upon Executive’s resignation for Good Reason. If Executive’s employment is terminated by the
Company without Cause (other than by reason of death or Disability) or Executive resigns for Good Reason (except as otherwise provided in Section 7(e)), Executive shall be entitled to receive: 
 (i) the Accrued Rights; 
 (ii) provided Executive (x) does not violate the restrictions set forth in Section 8 of this Agreement and (y) executes, delivers and does not revoke a general release of claims against Holdings, its

 (A) for a termination occurring on or prior to the second anniversary of the Effective Date, a lump sum payment equal to two

participation in such plan as in effect on the date of such termination for an additional twelve (12) months, payable as soon as practicable but no later than March 15 following the calendar year in which termination occurs. 
 (iii) Executive, his spouse and eligible dependents (to the extent covered immediately prior to such termination) shall continue to be
eligible to participate in all of the Company’s group health plans on the same terms and conditions as active employees of the Company until the earlier of (x) two (2) years from the date of termination of Executive’s employment
(the “Severance Period”), to the extent that Executive was eligible to participate in such plans immediately prior to the date of termination, or (y) until Executive is, or becomes, eligible for comparable coverage under the group
health plans of a subsequent employer, provided that, if Executive continues to receive benefits pursuant to this Section 

  

 5 

 
7(c)(iii) during a period of time during which, in the absence of the benefits provided in this Section 7(c)(iii), Executive would not otherwise be
entitled to continuation coverage under Section 4980B of the Internal Revenue Code of 1986, as amended (the “Code”), Executive shall receive reimbursement for all medical expenses on the date no later than the end of the calendar year
immediately following the calendar year in which the applicable expenses have been incurred. The COBRA health care continuation coverage period under Section 4980B of the Code, or any replacement or successor provision of United States tax law,
shall run concurrently with the Severance Period. 
 Following Executive’s termination of employment by the Company without Cause (other than by reason
of Executive’s death or Disability) or upon Executive’s resignation for Good Reason, except as set forth in this Section 7(c) or otherwise provided in Section 7(e), Executive shall have no further rights to any compensation or
any other benefits under this Agreement. 
 d. Expiration of Employment Term. (i) Election Not to Extend the
Employment Term. 
 (A) In the event Executive elects not to extend the Employment Term pursuant to Section 1,
unless Executive’s employment is earlier terminated pursuant to paragraphs (a), (b), (c), or (e) of this Section 7, the Employment Term shall expire and Executive’s employment hereunder shall terminate on the close of business on
the day immediately preceding the commencement of a subsequent Renewal Term, and Executive shall be entitled to receive the Accrued Rights. Executive shall have no further rights to any compensation or any other benefits under this Agreement.

 (B) In the event the Company elects not to extend the Employment Term pursuant to Section 1, unless Executive’s
employment is earlier terminated pursuant to paragraphs (a), (b), (c), or (e) of this Section 7, the Employment Term shall expire and Executive’s employment hereunder shall terminate on the close of business on the day immediately

 (A) the Accrued Rights; 
 (B) provided Executive (x) does not violate the restrictions set forth in Section 8 of this Agreement and (y) executes, delivers and does not revoke a general release of claims against Holdings, its

equal to two times the sum of: (1) Executive’s annualized Base Salary and (2) Executive’s Annual Bonus Target; and 
  

 6 

 (C) Executive, his spouse and eligible dependents (to the extent covered immediately
prior to such termination) shall continue to be eligible to participate in all of the Company’s group health plans on the same terms and conditions as active employees of the Company until the earlier of (x) termination of the Severance
Period, to the extent that Executive was eligible to participate in such plans immediately prior to the date of termination, or (y) until Executive is, or becomes, eligible for comparable coverage under the group health plans of a subsequent
employer, provided that, if Executive continues to receive benefits pursuant to this Section 7(e)(i)(C) during a period of time during which, in the absence of the benefits provided in this Section 7(e)(i)(C) Executive would not otherwise
be entitled to continuation coverage under Section 4980B of the Code, Executive shall receive reimbursement for all medical expenses on the date no later than the end of the calendar year immediately following the calendar year in which the
applicable expenses have been incurred. The COBRA health care continuation coverage period under Section 4980B of the Code, or any replacement or successor provision of United States tax law, shall run concurrently with the Severance Period.
The value of the Company-provided medical coverage contained herein will be reported as income to Executive. 
 (ii)
Section 4999. 
 (A) If, by reason of, or in connection with, any transaction that occurs after the Effective
Date, Executive would be subject to the imposition of the excise tax imposed by Section 4999 of the Code, but the imposition of such tax could be avoided by approval of shareholders described in Section 280G(b)(5)(B) of the Code, then
Executive may cause the Company or Holdings to seek such approval, in which case the Company and Holdings will use its reasonable best efforts to cause such approval to be obtained and Executive will cooperate and execute such waivers as may be
necessary so that such approval avoids imposition of any excise tax under Section 4999. If the Executive fails to cause the Company or Holdings to seek such approval, Exhibit I shall not apply and Executive shall not be entitled to any gross-up
payment for any resulting tax under Section 4999. If such approval, even if sought and obtained, would not avoid imposition of the excise tax imposed under Section 4999, then the provisions of Exhibit I attached hereto shall apply.

 (B) With respect to the imposition of the excise tax imposed by Section 4999 of the Code arising by reason of or in
connection with the Closing, Section 4.6 of the Employment Agreement between Executive and Holdings dated as of October 11, 2004, as amended on September 28, 2007 (the “Prior Agreement”) shall apply. The Gross-up Payment, as
defined in the Prior Agreement, that is attributable to the amount by which the LTIP Payment, as defined in Section 2.1 of the Deferred Share Agreement dated October 9, 2007 between Executive and Texas Energy Future Holdings Limited
Partnership (the “Deferred Share Agreement”), is reduced pursuant to Section 2.1 of the Deferred Share Agreement (the “Deferred Share Gross-Up”), shall be paid to Executive on January 2, 2008, subject to withholding for
federal income taxes, FICA taxes, and Section 4999 excise taxes. The parties agree that the Deferred Share Gross-Up, after application of the Additional Payment Agreement, shall equal $437,575, subject to federal income tax withholding of
$153,151.25, FICA withholding of $6,344.84, and Section 4999 withholding of $80,803. Any Gross-Up Payment otherwise due by reason of distributions pursuant to the Deferred Share Agreement shall be reduced by the amount of the Deferred Share
Gross-Up. 
  

 7 

 Following Executive’s termination of employment following a Change in Control, except as set forth in this
Section 7(e), Executive shall have no further rights to any compensation or any other benefits under this Agreement. 
 f. Notice of Termination. Any purported termination of employment by the Company or by Executive (other than due to Executive’s death) shall be communicated by written Notice of Termination to the other party hereto in
accordance with Section 9(j) hereof. For purposes of this Agreement, a “Notice of Termination” shall mean a notice which shall indicate the specific termination provision in this Agreement relied upon and shall set forth in reasonable
detail the facts and circumstances claimed to provide a basis for termination of employment under the provision so indicated. 
 8.
Restrictive Covenants. 
 a. In consideration of the Company entering into this Agreement with Executive and hereby
promising and committing itself to provide Executive with Confidential Information and/or specialized training after Executive executes this Agreement, Executive shall not, directly or indirectly: 
 (i) at any time during or after the Employment Term, disclose any Confidential Information pertaining to the business of the Company or
any of its Affiliates or the Sponsor Group or any of their respective Affiliates, except when required to perform his duties to the Company or one of its subsidiaries, by law or judicial process; 
 (ii) at any time during the Employment Term and for a period of eighteen (18) months thereafter (the “Non-Compete Period”),
directly or indirectly, act as a proprietor, investor, director, officer, employee, substantial stockholder, consultant, or partner in any Competing Business in Texas or any other geographic area in which the Company or its Affiliates operates or
conducts business; or 
 (iii) at any time during the Employment Term and for a period of eighteen (18) months
thereafter, directly or indirectly (A) solicit customers or clients of the Company or any of its Affiliates to terminate their relationship with the Company or any of its Affiliates or otherwise solicit such customers or clients to compete with
any business of the Company or any of its Affiliates, or (B) solicit or offer employment to any person who is, or has been at any time during the twelve (12) months immediately preceding the termination of Executive’s employment
employed by the Company or any of its Affiliates; 
 provided that in each of (ii) and (iii) above, such restrictions shall not apply with respect
to any member of the Sponsor Group or any of its Affiliates that is not engaged in any business that competes, directly or indirectly, with Holdings or any of its subsidiaries in any geographic area where they operate. Notwithstanding the foregoing,
for the purposes of Section 8(a), (A) Executive may, directly or indirectly own, solely as an investment, securities of any Person 

  

 8 

 
engaged in the business of the Company or its Affiliates which are publicly traded on a national or regional stock exchange or quotation system or on the
over-the-counter market if Executive (I) is not a controlling person of, or a member of a group which controls, such person and (II) does not, directly or indirectly, own 5% or more of any class of securities of such Person, and (B) the
Non-Compete Period shall not be triggered by any exercise of tag-along rights under the Sale Participation Agreement entered into between Executive and Texas Energy Future Holdings Limited Partnership (the “Sale Participation Agreement”)
or Drag Transaction (as defined in the Sale Participation Agreement) that may occur after the date hereof. 
 b.
Notwithstanding clause (a) above, if at any time a court holds that the restrictions stated in such clause (a) are unreasonable or otherwise unenforceable under circumstances then existing, the parties hereto agree that the maximum period,
scope or geographic area determined to be reasonable under such circumstances by such court will be substituted for the stated period, scope or area. Because Executive’s services are unique and because Executive has had access to Confidential
Information, the parties hereto agree that money damages will be an inadequate remedy for any breach of this Agreement. In the event of a breach or threatened breach of this Agreement, the Company or its successors or assigns may, in addition to
other rights and remedies existing in their favor, apply to any court of competent jurisdiction for specific performance and/or injunctive relief in order to enforce, or prevent any violations of, the provisions hereof (without the posting of a bond
or other security). 
 c. For purposes of this Section 8, the terms listed below shall be defined as follows: 

(i) Affiliate shall mean with respect to any Person, any entity directly or indirectly controlling, controlled by or under

 (ii) Competing Business shall mean any business that directly or indirectly competes, at the relevant determination date, with one
or more of the businesses of the Company, or its Affiliates in any geographic area where the Company or its Affiliates operate.

proprietary or confidential information, documents or materials in any form or media, including any of the foregoing relating to research, operations, finances, current and proposed products and services, customers, advertising and marketing, and
other non-public, proprietary, and confidential information of the Restricted Group, excluding any such non-public information that (i) is required by court or administrative order to be disclosed or (ii) becomes generally available to the
public other than as a result of Executive’s disclosure or failure to safeguard in violation of this Section 8. 
 (iv) Person shall mean “person,” as such term is used for purposes of Section 13(d) or 14(d) of the Securities Exchange Act of 1934, as amended (or any successor thereto). 
  

 9 

 (v) Restricted Group shall mean, collectively Holdings, its subsidiaries, the
members of the Sponsor Group and their respective Affiliates. 
 (v) Sponsor Group shall mean Kohlberg Kravis
Roberts & Co. L.P., TPG Capital L.P., and Goldman, Sachs & Co. 
 9. Miscellaneous. 
 a. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Texas without
regard to conflicts of laws principles thereof. 
 b. Entire Agreement. Except as otherwise provided herein, this
Agreement contains the entire understanding of the parties with respect to the employment of Executive by the Company and/or its affiliates and supersedes all prior agreements and understandings. There are no restrictions, agreements, promises,
warranties, covenants or undertakings between the parties with respect to the subject matter herein other than those expressly set forth herein. This Agreement shall not supersede (i) the Deferred Share Agreement, (ii) the Additional
Payment Agreement, (iii) Executive’s entitlement on January 2, 2008 to the LTIP Payment, as defined in the Deferred Share Agreement (subject to reduction as provided in Section 2.1 of the Deferred Share Agreement), and
(iv) Section 6.11 of the Merger Agreement. 
 c. No Waiver. The failure of a party to insist upon strict
adherence to any term of this Agreement on any occasion shall not be considered a waiver of such party’s rights or deprive such party of the right thereafter to insist upon strict adherence to that term or any other term of this Agreement.

 d. Severability. In the event that any one or more of the provisions of this Agreement shall be or become invalid,
illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions of this Agreement shall not be affected thereby. 
 e. Assignment. This Agreement, and all of Executive’s rights and duties hereunder, shall not be assignable or delegable by
Executive. Any purported assignment or delegation by Executive in violation of the foregoing shall be null and void ab initio and of no force and effect. This Agreement may be assigned by the Company to a person or entity which is an affiliate or a
successor in interest to substantially all of the business operations of the Company. Upon such assignment, the rights and obligations of the Company hereunder shall become the rights and obligations of such affiliate or successor person or entity.

 f. Set Off; Mitigation. The Company’s obligation to pay Executive the amounts provided and to make the
arrangements provided hereunder shall not be subject to setoff, counterclaim or recoupment of amounts owed by Executive to the Company or its affiliates. Executive shall not be required to mitigate the amount of any payment provided for pursuant to
this Agreement by seeking other employment. 
  

 10 

 g. Compliance with Section 409A of the Code. Notwithstanding anything herein
to the contrary, if, at the time of Executive’s termination of employment with the Company, the Company has securities which are publicly traded on an established securities market, and Executive is a “specified employee” (as defined
in Section 409A of the Code), and the deferral of the commencement of any payments or benefits otherwise payable pursuant to Section 7 as a result of such termination of employment is necessary in order to prevent any accelerated or
additional tax under Section 409A of the Code, then, to the extent permitted by Section 409A of the Code, the Company will defer the commencement of the payment of any such payments or benefits hereunder (without any reduction in such
payments or benefits ultimately paid or provided to Executive) until the date that is six (6) months following Executive’s termination of employment with the Company (or the earliest date as is permitted under Section 409A of the
Code), provided that amounts which do not exceed the limits set forth in Section 402(g)(1)(B) of the Code in the year of such termination shall be payable immediately upon termination. If any payments or benefits are deferred due to such
requirements, such amounts will be paid in a lump sum to Executive at the end of such six (6) month period. The Company shall consult with Executive in good faith regarding the implementation of the provisions of this Section 9(g).

 h. Indemnity. The Company agrees that it shall indemnify and hold Executive harmless to the fullest extent permitted
by law from and against any and all liabilities, costs, claims and expenses relating to a third party claim including without limitation all costs and expenses incurred in defense of litigation, including attorneys’ fees, arising out of the
performance of his duties other than such liability (if any) that he may incur by his own actual fraud or intentional misconduct or which is not entitled to indemnification as a matter of law. The Company will insure Executive, for the duration of
his employment, and thereafter, as long as he cooperates with the Company as required by Section 9(n) of this Agreement with respect to any claims against the Company, in respect of his acts and omissions occurring during such employment under
a contract of directors and officers liability insurance to the extent that the Company maintains any such insurance to insure members of the Board. 
 i. Successors; Binding Agreement. This Agreement shall inure to the benefit of and be binding upon personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and
legatees.

 Exhibit I 
 Paragraph 1. In the event it shall be determined that any payment, benefit or distribution (or combination thereof) by the Company, any of its affiliates, or one or more trusts established by the Company or any of its affiliates for
the benefit of their employees, to or for the benefit of Executive (whether paid or payable or distributed or distributable pursuant to the terms of this Agreement, or otherwise) (a “Payment”) is subject to the excise tax imposed by
Section 4999 of the Code or any interest or penalties are incurred by Executive with respect to such excise tax (such excise tax, together with any such interest and penalties, hereinafter collectively referred to as the “Excise
Tax”), Executive shall be entitled to receive an additional payment (a “Gross-Up Payment”) in an amount such that after payment by Executive of all taxes (including any interest or penalties imposed with respect to such
taxes), including, without limitation, any income taxes (and any interest and penalties imposed with respect thereto) and the Excise Tax imposed upon the Gross-Up Payment, Executive retains an amount of the Gross-Up Payment equal to the Excise Tax
imposed upon the Payments. 
 Paragraph 2. All determinations required to be made under this Exhibit I, including whether and when a Gross-Up Payment
is required and the amount of such Gross-Up Payment and the assumptions to be utilized in arriving at such determination, shall be made by Deloitte & Touche LLP or such other nationally recognized certified public accounting firm as
may be designated by the Company (the “Accounting Firm”) which shall provide detailed supporting calculations both to the Company and Executive within ten (10) business days of the receipt of notice from Executive that there has been
a Payment, or such earlier time as is requested by the Company; provided that for purposes of determining the amount of any Gross-Up Payment, Executive shall be deemed to pay federal income tax at the highest marginal rates applicable to individuals
in the calendar year in which any such Gross-Up Payment is to be made and deemed to pay state and local income taxes at the highest effective rates applicable to individuals in the state or locality of Executive’s residence or place of
employment in the calendar year in which any such Gross-Up Payment is to be made, net of the maximum reduction in federal income taxes that can be obtained from deduction of such state and local taxes, taking into account limitations applicable to
individuals subject to federal income tax at the highest marginal rates. All fees and expenses of the Accounting Firm shall be borne solely by the Company. Any Gross-Up Payment, as determined pursuant to this Exhibit I, shall be paid by the Company
to Executive (or to the appropriate taxing authority on Executive’s behalf) when due. If the Accounting Firm determines that no Excise Tax is payable by Executive, it shall so indicate to Executive in writing. Any determination by the
Accounting Firm shall be binding upon the Company and Executive (subject to Paragraph 3). As a result of the uncertainty in the application of Section 4999 of the Code, it is possible that the amount of the Gross-Up Payment determined by
the Accounting Firm to be due to (or on behalf of) Executive was lower than the amount actually due (“Underpayment”). In the event that the Company exhausts its remedies pursuant to Paragraph 3 of Exhibit I and Executive thereafter is
required to make a payment of any Excise Tax, the Accounting Firm shall determine the amount of the Underpayment that has occurred, and any such Underpayment shall be promptly paid by the Company to or for the benefit of Executive (but in any case
no later than the calendar year following the calendar year in which such tax was payable). 
  

 14 

 Paragraph 3. Executive shall notify the Company in writing of any claim by the Internal Revenue Service that, if
successful, would require the payment by the Company of any Gross-Up Payment. Such notification shall be given as soon as practicable but no later than ten (10) business days after Executive is informed in writing of such claim and shall
apprise the Company of the nature of such claim and the date on which such claim is requested to be paid. Executive shall not pay such claim prior to the expiration of the thirty (30) day period following the date on which it gives such notice
to the Company (or such shorter period ending on the date that any payment of taxes with respect to such claim is due). If the Company notifies Executive in writing prior to the expiration of such period that it desires to contest such claim,
Executive shall (i) give the Company any information reasonably requested by the Company relating to such claim, (ii) take such action in connection with contesting such claim as the Company shall reasonably request in writing from time to
time, including, without limitation, accepting legal representation with respect to such claim by an attorney reasonably selected by the Company, (iii) cooperate with the Company in good faith in order to effectively contest such claim and
(iv) permit the Company to participate in any proceedings relating to such claim; provided, however, that the Company shall bear and pay directly all costs and expenses (including additional interest and penalties) incurred in
connection with such contest and shall indemnify and hold Executive harmless, on an after-tax basis, for any Excise Tax or income tax (including interest and penalties with respect thereto) imposed as a result of such representation and payment of
costs and expenses. Without limitation on the foregoing provisions of this Paragraph 3, the Company shall control all proceedings taken in connection with such contest and, at its sole option, may pursue or forego any and all administrative appeals,
proceedings, hearings and conferences with the taxing authority in respect of such claim and may, at its sole option, either direct Executive to pay the tax claimed and sue for a refund or contest the claim in any permissible manner, and Executive
agrees to prosecute such contest to a determination before any administrative tribunal, in a court of initial jurisdiction and in one (1) or more appellate courts, as the Company shall determine; provided that if the Company directs Executive
to pay such claim and sue for a refund, the Company shall advance the amount of such payment to Executive, on an interest-free basis, and shall indemnify and hold Executive harmless, on an after-tax basis, from any Excise Tax or income tax
(including interest or penalties with respect thereto) imposed with respect to such advance or with respect to any imputed income with respect to such advance; provided, further, that if Executive is required to extend the statute of
limitations to enable the Company to contest such claim, Executive may limit this extension solely to such contested amount. The Company’s control of the contest shall be limited to issues with respect to which a Gross-Up Payment would be
payable hereunder and Executive shall be entitled to settle or contest, as the case may be, any other issue raised by the Internal Revenue Service or any other taxing authority. 
 Paragraph 4. If, after the receipt by Executive of an amount paid or advanced by the Company pursuant to this Exhibit I, Executive becomes entitled to receive any refund with respect to a Gross-Up Payment,
Executive shall (subject to the Company’s complying with the requirements of Paragraph 3 of this Exhibit I) promptly pay to the Company the amount of such refund received (together with any interest paid or credited thereon after taxes
applicable thereto). If, after the receipt by Executive of an amount advanced by the Company pursuant to Paragraph 3 of this Exhibit I, a determination is made that Executive shall not be entitled to any refund with 

  

 15 

 
respect to such claim, and the Company does not notify Executive in writing of its intent to contest such denial of refund prior to the expiration of thirty
(30) days after such determination, then such advance shall be forgiven and shall not be required to be repaid, and the amount of such advance shall offset, to the extent thereof, the amount of the Gross-Up Payment required to be paid.

 Paragraph 5. For the avoidance of doubt, all payments to or for the benefit of Executive provided for in this Exhibit I or pursuant to
Section 4.6 of the Original Employment Agreement shall be made no later than the end of the calendar year in which the applicable Excise Tax has become due, or if as a result a tax audit or litigation, it is determined that no additional Excise
Tax has become due, the end of the calendar year in which the audit is completed or there is a final and non-appealable settlement or other resolution. 
  

 16Additional Payment Agreement, dated October 10, 2007

 Exhibit 10(ff) 
  

			
	  	  	PRIVILEGED AND CONFIDENTIAL
	  	  	Execution Version JAB

 ADDITIONAL PAYMENT AGREEMENT 
 ADDITIONAL PAYMENT AGREEMENT, dated as of the 10th day of October, 2007 (this “Agreement”), by and between TXU Corp. (which is expected
to be renamed Energy Future Holdings Corp. following the Merger (as defined below)), a Texas corporation (the “Company”), Texas Energy Future Holdings Limited Partnership, a Delaware limited partnership (the
“Parent”), Texas Competitive Electric Holdings LLC, a Delaware limited liability company (the “Holdings”), and James A. Burke (the “Executive”). 
 WHEREAS, pursuant to an Agreement and Plan of Merger (the “Merger Agreement”) dated February 25, 2007, by and among Parent, Texas
Energy Future Merger Sub Corp, a Texas corporation (“Merger Sub”), and the Company, Merger Sub will be merged with and into the Company (the “Merger”), with the Company surviving the Merger as a subsidiary of
Parent. 
 WHEREAS, the Company and Executive have previously agreed that, in consideration of Executive’s dedicated service to the
Company and in order to ensure that the compensation and benefits expectations of Executive will be satisfied, in the event it shall be determined that any payment, benefit or distribution in the nature of compensation (within the meaning of section
280G(b)(2) of the Code) to or for the benefit of Executive, whether paid, payable or provided by the Company or any of its affiliates or their respective successors or assigns, pursuant to this Agreement, any benefit plan, stock incentive plan,
employment or severance agreement or otherwise (collectively, the “Payments”), would be subject to the excise tax imposed by section 4999 of the Code (together with any interest or penalties imposed with respect to such excise tax,
the “Excise Tax”), then Executive shall be entitled to receive an additional payment (the “Gross-Up Payment”) in an amount such that, after payment by Executive of all taxes (and any interest or penalties imposed
with respect to such taxes), including, without limitation, any income taxes (and any interest and penalties imposed with respect thereto) and the Excise Tax imposed upon the Gross-Up Payment, Executive retains an amount of the Gross-Up Payment
equal to the Excise Tax imposed upon the Payments. 
 WHEREAS, the parties hereto agree that Executive will be entitled to receive a Gross-Up
Payment in an amount such that, after payment of all taxes imposed pursuant to Section 409A of the Code (and any interests and penalties imposed with respect to such taxes) resulting from Executive’s execution of this Agreement and the
establishment and funding of the Trust, Executive retains an amount of the Gross-Up Payment equal to the excise tax imposed upon the Payments; provided, however, Executive shall not be entitled under this Agreement to an additional payment in
respect of any taxes, interests or penalties imposed with respect to such taxes pursuant to Section 409A of the Code in connection with any payments or benefits not covered hereunder. 
 WHEREAS, the Company agrees to calculate the amount of the Gross-Up Payment payable on behalf of Executive to the Internal Revenue Service (the
“Service”) in good faith and in accordance with a reasonable interpretation of the Code as to the amount of the Excise Tax which may be imposed on Executive with respect to payments made by the Company and, in reliance on the
Company’s commitments set forth in this Agreement, Executive agrees to accept such calculation. 
 WHEREAS, because of the uncertainties
involved in calculating the exact amount of the payments that will be subject to the Excise Tax, which in turn affects the extent to which a Gross-Up Payment is necessary, the parties desire to have the Company set aside certain proceeds in order to
satisfy any subsequent claims by the Service that the amount of Excise Tax that was paid on such Payments was insufficient. 

 WHEREAS, in the event the Gross-Up Payment made by the Company to Executive is insufficient to cover the
additional Excise Tax that becomes due and owing to the Service, the Company agrees to indemnify and hold Executive harmless in respect of any Excise Tax by setting aside in the Trust (as defined below), the amount set forth on Exhibit A
representing the difference between a calculation using a method consistent with Treasury Regulation § 1.280G-1 and a calculation assuming that all payments are subject to Excise Tax (the “Additional Payment”). 
 WHEREAS, the Company has also agreed that, in addition to the Additional Payment, the Company shall indemnify and hold Executive harmless from any and
all liabilities (including interest and penalties) that result from Executive entering into this Agreement and the funding of the Trust. 
 WHEREAS, the Company and Executive previously agreed to the terms of the cash award that will be payable to Executive for the 2007 calendar year and the parties desire to memorialize the terms and conditions of such bonus in this Agreement.

 NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS: 
 1. Effective Time. This Agreement shall become effective upon the Effective Time (as defined in the Merger Agreement) and shall remain in effect until the later of (i) the closing of the later of
(A) the Company’s or (B) Executive’s, tax year that follows the expiration of the statute of limitations for which the Service may audit the tax year in which the Service could claim that an underpayment of the Excise Tax for
such year was paid and (ii) the resolution and settlement with the Service as to any contested claim. If the Merger Agreement is terminated in accordance with its terms prior to the Effective Time, this Agreement shall automatically terminate
and shall be null and void ab initio and of no further force and effect. 
 2. 2007 Bonus Payment. Executive shall be
entitled to receive a cash bonus with respect to the 2007 calendar year (the “2007 Award”) under and subject to the terms and conditions of the Company’s Annual Incentive Plan (the “AIP”); provided that such
bonus payment shall not be less than the percentage of the Target Incentive Pool (as defined in the AIP) used in determining the 2007 Award for all other participants in the AIP and with a personal modifier of at least 100%; provided further, in the
event that Executive’s employment with the Company terminates (i) prior to December 31, 2007, Executive shall be entitled to receive an amount of the 2007 Award prorated on the basis of the number of months Executive was employed by
the Company during 2007, with the month of termination counting as a full month for this purpose, or (ii) on or after December 31, 2007, but prior to the date that the 2007 Award is paid to Executive, then Executive shall receive the same
2007 Award as Executive would have received if Executive was employed by the Company on the date that the 2007 Award is paid. The 2007 Award shall be paid to Executive at the same time that the 2007 Award is paid to other recipients of such award
who are employed by the Company. 
 3. Amount of Additional Gross-up Payment. (a) The determinations as to the Additional Payment for
purposes of this Agreement shall be made by Alvarez & Marsal Taxand LLC (“A&M”), and approved by Deloitte & Touche USA LLP, such approval not to be unreasonably withheld (the “Accounting
Firm”). All fees and expenses of A&M and the Accounting Firm shall be borne solely by the Company. 
  

 2 

 (b) (i) If at any time after the Effective Time, Executive receives a claim from the
Service of an underpayment of the Excise Tax on the Payments, Executive shall notify the Company in writing of such claim by the Service. Such notification shall be given as soon as practicable after Executive receives actual notice in writing of
such claim by the Service. The Executive shall apprise the Company of the nature of such claim and the date on which such claim is requested to be paid. The Executive shall not pay such claim prior to the expiration of the 30-day period following
the date on which Executive gives such notice to the Company (or the date that any payment of taxes with respect to such claim is due pursuant to the notice from the Service, if shorter). The Company shall provide notice to Executive in writing
regarding whether it will contest such claim no later than 5 business days prior to the date on which the amount of such claim is required to be paid. To the extent the Trust has sufficient funds available, the Company shall direct the Trustee to
pay to Executive (or the Company shall pay to Executive) prior to the date on which Executive must pay the claim to the Service the amount necessary for Executive to satisfy the claim by the Service for all or the portion of the Additional Payment
set forth in such claim, plus any interest and penalties imposed as a result of such claim, on an after-tax basis. If the Company notifies Executive that the Company desires to contest such claim, Executive shall: 
 (A) give the Company information reasonably requested by the Company relating to such claim, 
 (B) reasonably cooperate with the Company in good faith in order to contest such claim and take such action in connection with such claim
as the Company shall reasonably request in writing, and 
 (C) permit the Company to participate in any proceedings relating
to such claim and accept legal representation with respect to such claim by an attorney reasonably selected by the Company. 
 In the event that in
connection with such contest Executive is required to pay the claim prior to the final resolution, to the extent the Trust has sufficient funds available, the Company shall direct the Trustee to pay to Executive (or the Company shall pay to
Executive) prior to the date on which Executive must pay the claim to the Service the amount necessary for Executive to satisfy the claim by the Service for all or the portion of the Additional Payment set forth in such claim, plus any interest and
penalties imposed as a result of such claim, on an after-tax basis. 
 (ii) The Company shall bear and pay directly all costs
and expenses (including additional interest and penalties) incurred in connection with such contest identified in subsection (b)(i) above, and shall indemnify and hold Executive harmless, on an after-tax basis, for any Excise Tax or income tax
(including interest and penalties) imposed as a result of such representation and payment of costs and expenses. Without limitation on the foregoing provisions of this Section 3(b), the Company shall control all proceedings taken in connection
with such contest, and, at its sole discretion, may pursue or forgo any and all administrative appeals, proceedings, hearings and conferences with the applicable taxing authority in respect of such claim and may, at its sole discretion, either pay
the tax claimed to the appropriate taxing authority on behalf of Executive and direct Executive to sue for a refund or contest the claim in any permissible manner, and Executive agrees to prosecute such contest to a determination before any
administrative tribunal, in a court of initial jurisdiction and in one or more appellate courts, as the Company shall determine; provided, however, that, if the Company pays such claim and directs Executive 

  

 3 

 
to sue for a refund, the Company shall indemnify and hold Executive harmless, on an after-tax basis, from any Excise Tax or income tax (including interest or
penalties) imposed with respect to such payment or with respect to any imputed income in connection with such payment. Furthermore, the Company’s control of the contest shall be limited to issues with respect to the Additional Payment or to
which Executive has any liability as a result of his entering into this Agreement or the funding of the Trust, and Executive shall be entitled to settle or contest, as the case may be, any other issue raised by the Service or any other taxing
authority. 
 (c) If, after the receipt by Executive of an Additional Payment or payment by the Company of an amount on
Executive’s behalf pursuant to Section 3(b), Executive becomes entitled to receive any refund with respect to the Excise Tax to which such Additional Payment relates or with respect to such claim, Executive shall (subject to the
Company’s complying with the requirements of Section 3(b), if applicable) as soon as practicable pay to the Company the amount of such refund (together with any interest paid or credited thereon by the Service after taxes applicable
thereto). If, after payment by the Company of an amount on Executive’s behalf pursuant to Section 3(b), a determination is made that Executive shall not be entitled to a refund with respect to such claim and the Company does not notify
Executive in writing of its intent to contest such denial of refund prior to the expiration of 30 days after such determination, then the amount previously paid by the Company shall offset, to the extent thereof, the amount of Additional Payment
required to be paid. 
 (d) The following payments shall in all events be paid as follows: 
 (1) Any Additional Payment, as determined pursuant to this Section 3, shall be paid by the Company to Executive prior to the date on
which such amount is due to the Service. Notwithstanding any other provision of this Section 3, the Company may, in its sole discretion, withhold and pay over to the Service or any other applicable taxing authority, for the benefit of
Executive, all or any portion of any Additional Payment, provided that such payment is paid no later than required by the Service, and Executive hereby consents to such withholding; and, 
 (2) Any expenses, as determined pursuant to this Section 3, incurred by Executive in connection with a contest respecting the
existence or amount of any Excise Tax to which Executive may be entitled pursuant to Section 3(b) above shall be paid directly by Company and the Company shall fully gross-up Executive with respect to any income recognized by Executive as a
result of income taxes that Executive is required to pay with respect to such expenses being paid by the Company. 
 4. Establishment of
Trust. In furtherance of its obligations hereunder, the Company hereby agrees to establish a trust as of October 10, 2007, in the form attached hereto as Exhibit “A,” for the benefit of Executive pursuant to the terms herein (the
“Trust”). To the extent not paid by the Company, the Additional Payments shall be paid to the Service or Executive, in accordance with and pursuant to the terms and conditions of the Trust and this Agreement. If paid by the Company,
it shall be entitled to reimbursement from the Trust in accordance with and pursuant to the terms and conditions thereof. 
 5.
Indemnification. As further inducement for Executive to enter into this Agreement, the Company shall indemnify and hold Executive harmless on an after-tax basis, for any Excise Tax due under section 4999 of the Code, excise tax under section
409A of the Code or income tax (including interest and penalties) imposed as a result of the establishment and funding of the Trust or that result from the Company’s or Executive’s obligations under this Agreement. 
  

 4 

 6. Delayed Payment Date. To the extent any amounts payable to Executive or on Executive’s
behalf under this Agreement are deemed to be deferred compensation subject to the requirements of section 409A of the Code and the delay of such payments to Executive could avoid adverse tax treatment and even where the delay would avoid adverse tax
treatment, the Company shall not delay the payment to Executive for such amounts and shall pay to Executive or on Executive’s behalf such amounts when required to be paid under this Agreement. The Company shall also pay to Executive an
additional amount, if applicable, to cover the excise tax under section 409A of the Code that results from the failure to delay such payments, plus an additional amount to cover any income taxes thereon (plus interest and penalties) because of the
failure to comply with such requirements and an additional amount to cover the Excise Tax on such amount so that on an after-tax basis Executive shall be in the same position as if there were no excise tax under section 409A of the Code assessed on
such amounts. 
 7. Miscellaneous. (a) No Waiver. The waiver by a party of the violation of any of the provisions of this Agreement,
whether express or implied, shall not operate or be construed as a waiver of any subsequent violation of any such provision. 
 (b) Amendment. This Agreement may not be amended, modified or cancelled except by written consent of the parties. 
 (c) Severability. In the event that any provision or portion of this Agreement shall be determined to be invalid or unenforceable for any reason, the remaining provisions of this Agreement shall remain in full force and effect to the
fullest extent permitted by law. 
 (d) Joint and Several Liability. As a party to this Agreement, in the event that the
Company does not fully satisfy its obligations hereunder, Parent and Holdings expressly agree that they shall be jointly and severally liable for the Company’s obligations and Executive shall be able to enforce his rights under this Agreement
against Parent and Holdings in the event the Company does not satisfy its obligations. 
 (e) Legal Fees. The Company agrees
that Executive shall not be responsible for the incurrence of any legal fees that result from the enforcement of his rights under this Agreement and in the event there is any dispute under this Agreement between the Company and Executive, the
Company agrees to pay, on an after-tax basis, all legal fees and other expenses incurred by Executive in a good faith dispute. 
 (f) Binding Effect. This Agreement shall be binding upon and inure to the benefit of Executive, the Company, Parent, Holdings, their affiliates, and any successor organization or organizations which shall succeed to the business and
property of the Company, Parent and Holdings, whether by means of merger, consolidation, acquisition of substantially all the assets of the Company, Parent and Holdings or otherwise, including by operation of law. 
 (g) Governing Law. This Agreement has been made in and shall be governed and construed in accordance with the laws of the State of Texas.

  

 5 

 (h) Counterparts. This Agreement may be executed in any number of counterparts, each of
which shall be an original with the same effect as if the signatures were all affixed to the same instrument. 
 8. Written Agreement.
This Agreement memorializes all oral discussions between the parties relating to the Gross-Up Payment and Additional Payment and is intended to be the controlling document with respect to the Company’s obligations with respect to the setting
aside of the Additional Payment in the event the Service makes a successful claim for such; provided, however, this Agreement does not, and is not intended to, supersede any written agreements that the parties have previously entered into that cover
the Gross-Up Payment and Executive continues to have those rights afforded to him under such agreements and the Company agrees and affirms that such agreements shall continue in force and effect. 
 9. Notices. All notices and other communications hereunder shall be in writing and shall be given by hand delivery to the other party or by
registered or certified mail, return receipt requested, postage prepaid, addressed as follows:
