Additional Payment Agreement, dated October 10, 2007

 Exhibit 10(u) 
 C. JOHN WILDER 
 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 Company LLC, a Delaware limited
liability company (the “Holdings”), and C. John Wilder (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, pursuant to Section 4.6 of the Employment Agreement between the Company and Executive, dated February 21, 2004 (the “Employment Agreement”), 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”), and/or the additional tax imposed by Section 409A of the Code (together with any interest or penalties imposed with respect to such additional
tax, the “Additional 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 and/or Additional 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 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 a secular 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”). For the
avoidance of doubt, the amount of the Additional Payment shall not limit the Company’s liability or obligations hereunder. 
 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. 
 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. 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 Tax-and LLC (“A&M”), and approved by
Deloitte & Touche USA LLP, or such other nationally recognized certified public accounting firm as may be designated by the Company (the “Accounting Firm”), which approval shall not be unreasonably withheld. A&M and the
Accounting Firm shall provide detailed supporting calculations both to the Company and Executive within 15 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. All
fees and expenses of Accounting Firm shall be borne solely by the Company. 
 (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, or an imposition of an Additional 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. If the
Company determines not to contest the claim, it shall pay to Executive (or cause the Trust to 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,

  

 2 

 (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, the Company shall pay to Executive (or cause the Trust to 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, Additional 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 2(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 to sue for a refund, the Company shall indemnify and hold Executive
harmless, on an after-tax basis, from any Excise Tax, Additional 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 2(b), Executive becomes entitled to receive any refund with respect to the Excise Tax or
Additional 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 2(b), if applicable) as soon as practicable pay to the Company the
amount of such refund. If, after payment by the Company of an 

  

 3 

 
amount on Executive’s behalf pursuant to Section 2(b), a determination is made that Executive shall not be entitled to a refund (together with any
interest paid or credited thereon by the Service after taxes applicable thereto) 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 2, 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 2, 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; 
 (2) Any expenses, as determined pursuant to this Section 2, incurred by Executive in connection with a contest respecting the
existence or amount of any Excise Tax or Additional Tax to which Executive may be entitled pursuant to Section 2(b) above within 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; and 
 (3) Within five days after Executive submits a claim for reimbursement to which Executive may be entitled under this Agreement for an expense incurred during the term of this Agreement, including, but not limited to,
any Additional Payment with respect to the interest or penalty component of an Excise Tax, shall be paid by the Company to Executive. The amount of any such expenses eligible for reimbursement paid during an Executive’s taxable year shall not
affect the expenses eligible for reimbursement in any other taxable year, and the right to any such expense reimbursement may not be liquidated or exchanged for any other benefit. 
 Notwithstanding the foregoing, in no event shall the foregoing payments be paid later than (A) the end of Executive’s taxable year next following Executive’s taxable year in which (x) with respect
to subsections (d)(1) and (d)(2) above, the Excise Tax and/or Additional Tax (and any income or other related taxes or interest or penalties thereon) on a payment are remitted to the Service or any other applicable taxing authority or, in the case
of amounts relating to a claim described in Section 2(b) that does not result in the remittance of any federal, state, local and foreign income, excise, social security and other taxes, the calendar year in which the claim is finally settled or
otherwise resolved or (y) with respect to subsection (d)(3) above, the expense was incurred, and (B) the end of the six month period described in Section 5 below, if applicable. 
 3. 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 amounts under the Trust shall be paid, 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. 
  

 4 

 4. 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 or income tax (including, but not limited to, any additional income tax under Section 409A of the Code) (including interest
and penalties) imposed as a result of the establishment and funding of the Trust. 
 5. Delayed Payment Date. Notwithstanding any
provision to the contrary in this Agreement, (i) if Executive is deemed at the time of his or her termination of employment to be a “key employee” within the meaning of that term under Code Section 416(i) (as used for purposes of
defining a “specified employee” under Section 409A of the Code) and delayed payment of an amount that is payable to or on behalf of Executive in connection with a termination of employment is required in order to avoid a
prohibited distribution under Section 409A(a)(2) of the Code, no such amount shall be provided to or paid on behalf of Executive prior to the earlier of (x) the expiration of the six (6)-month period measured from the date of
Executive’s “separation from service” (as such term is defined in Treasury Regulations issued under Code Section 409A) or (y) the date of Executive’s death; provided however, upon the expiration of the applicable Code
Section 409A(a)(2) delay period referred to herein, all amounts delayed pursuant to this Section 6 shall be promptly paid to or on behalf of Executive in a lump sum; and (ii) if any other payments of money or other benefits due to
Executive hereunder could cause the application of an accelerated or additional tax under Section 409A of the Code, such payments or other benefits shall be deferred if deferral will make such payment or other benefits compliant under
Section 409A of the Code, or otherwise such payment or other benefits shall be restructured, to the extent possible, in a manner, determined by the Company, that does not cause such an accelerated or additional tax. Whether an Executive is a
“key employee” for purposes of this Section 5 shall be determined in accordance with the written guidelines adopted by the Company for making such determinations. The parties do not expect that Executive will be a specified employee
on the date of his expected termination of employment. 
 6. 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) 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. 
  

 5 

 (e) Governing Law. This Agreement has been made in and shall be governed and
construed in accordance with the laws of the State of Texas. 
 (f) 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. 
 7.
Written Agreement. Except as otherwise provided herein, and in the Severance and Release Agreement, between the Company and the Executive, dated October 10, 2007, this Agreement sets forth the entire agreement and understanding of the
parties with respect to the matters covered hereby, including, without limitation, the amount of the Additional Payment which shall be paid from the Trust. This Agreement supersedes all prior agreements and understandings (including verbal
agreements) between Executive and the Company and/or its affiliates regarding the terms and conditions of Executive’s entitlement to, and Company’s obligation to pay, any Gross-Up Payment or Additional Payment in connection with any
payments or benefits provided to Executive; provided, however that nothing herein shall adversely affect Executive’s rights under Section 4.6 of his Employment Agreement.

 9. The first sentence of Section 3.5(c) of the Agreement is amended to read in its entirety as follows: 

(c) The Additional Retirement Compensation shall be payable at the time and in the form as provided under the Supplemental Retirement
Plan. 
 10. The Agreement is amended to add a new Section 3.9 to read as follows: 
 3.9 Treatment of Outstanding Performance Unit Awards. Notwithstanding any other provision contained in this Agreement or any
agreement underlying any award issued to Executive under the LTICP to the contrary, any performance units awarded to the Executive and outstanding under the LTICP at the time of a Change of Control Event (as defined in this Section 3.9) to the
extent not previously vested shall become fully vested at such time. In the event the consideration to be received by shareholders in connection with a Change in Control Event is solely cash, the performance units shall be valued based upon the
product of (x) the number of shares payable pursuant to each performance award (adjusted to reflect the Company’s attainment or non-attainment of the performance criteria set forth in the applicable award agreement), and (y) the Sale
Price; provided, however, that with respect to awards granted in 2007, the awards shall be subject to any caps on the performance achievement levels specified in the applicable award agreement. The determination of the adjustment (if any) set
forth in clause (x) above shall be made by the Organization and Compensation Committee of the Company’s Board of Directors prior to the effective time of such Change in Control Event and, for performance units based on relative total
shareholder return, measured based on (a) of the applicable peer companies, total shareholder return from the beginning of the relevant performance period through the close of trading on the New York Stock Exchange (or, in the case of peer
companies whose shares do not trade on the New York Stock Exchange, the primary exchange on which such shares are traded) on the last trading day prior to the Change in Control Event, as compared to and measured against (b) the Company’s
total shareholder return from the beginning of the relevant performance period through the effective time of the Change in Control Event, using the Sale Price as defined in this Section 3.9 as the value of the Company’s common stock on
such effective time. The value of the LTICP award(s) shall be paid to Executive in cash on the later of (i) the date of the Change in Control Event, and (ii) January 2, 2008. This Section 3.9 shall not operate to defer the
payment of performance units that become payable prior to the occurrence of a Change in Control Event. For purposes hereof, a “Change in Control Event” shall mean one or more acquisitions, by any individual, entity or group (within the
meaning of Treas. Reg. §§1.409A-3(i)(5)(v)(B) and (vi)(D)) (a “Person”) that results in (i) the ownership by such Person of more than 90% of the outstanding voting securities of the Company; and (ii) neither the Company
nor the acquiring Person (or any affiliate of the Company or the acquiring Person) having any publicly traded voting equity securities on any public securities exchange. For purposes hereof, the “Sale Price” shall mean the price per share
of Company common stock to be paid by an acquiror as set forth in the applicable 

  

 3 

 
transaction document (which in the case of the Transaction shall be the Per Share Merger Consideration, as defined in the Merger Agreement) or if there is no
price per share set forth in the applicable transaction document, the Fair Market Value, as defined in the LTICP, per share on the day before the Change in Control Event. 
 11. Section 4.2(d) of the Agreement is amended to read in its entirety as follows: 
 (d)
Any amount of Executive’s accounts under the TXU Deferred and Incentive Compensation Plan (“DICP”) and the TXU Salary Deferral Program (“SDP”) (valued as of the date of such termination in accordance with the valuation
methodology used under such plans) that would otherwise be forfeited, shall become fully vested. Furthermore, any account Executive may hold under the DICP shall be credited with the matching contributions that would have been made on behalf of
Executive under the DICP had Executive continued to defer salary under the DICP at the rate in effect as of the date of such termination for an additional twelve (12) months. Notwithstanding anything contained herein, Executive’s accounts
under the DICP and/or SDP shall be paid to Executive at such time and in such form as otherwise payable under the terms of the DICP and/or SDP, as applicable. 
 12. If and only if the Transaction occurs, effective upon the Closing, Section 4.5(c) of the Agreement is amended to read in its entirety as follows 
 (c) All outstanding LTICP Awards shall not forfeit and shall be paid at the times and in the amounts provided for in, and subject to the
terms and conditions of, Section 3.9. In addition, notwithstanding any other provision contained in this Agreement or any agreement underlying any award issued to Executive under the LTICP to the contrary, and subject to clause (iv) below,
all obligations related to ungranted awards that would have been made to Executive under the LTICP pursuant to Section 3.4 on or prior to the expiration date of the initial 5-year Term shall be satisfied in the following way: 
  

	 	(i)	If the Executive shall not have received a grant of an award under the LTICP with respect to 2008 or 2009, Executive shall receive an immediate payment in cash in an amount equal to
the Per Share Merger Consideration (as defined in the Merger Agreement) multiplied by 80,000. 

  

	 	(ii)	If the Executive shall have received an award under the LTICP with respect to 2008, but not with respect to 2009, Executive shall receive an immediate payment in cash in an amount
equal to the Per Share Merger Consideration multiplied by 40,000. 

  

	 	(iii)	If the Executive shall have received awards under the LTICP with respect to 2008 and 2009, no additional payment or awards shall be made to Executive under this Section 4.5(c)
and Executive shall have no right to any payment of any additional amount or grant of any additional award under this Section 4.5(c). 

  

 4 

	 	(iv)	Notwithstanding clauses (i) through (iii) above, if such termination occurs prior to the end of the 7 month anniversary of the Closing, then Executive shall receive an
immediate payment in cash in an amount equal to the Per Share Merger Consideration (as defined in the Merger Agreement) multiplied by 80,000, reduced by any cash payment previously received in respect of any annual LTICP Award for 2008 or 2009
granted pursuant to Section 3.4, and such payment shall extinguish any and all rights Executive may have to any annual LTICP awards for 2008 or 2009, whether or not such awards are outstanding at the time of such termination.

 13. Section 4.5(d) of the Agreement is amended to read in its entirety as follows: 
 (d) Any amount of Executive’s accounts under the TXU Deferred and Incentive Compensation Plan (“DICP”) and the TXU Salary
Deferral Program (“SDP”) (valued as of the date of such termination in accordance with the valuation methodology used under such plans) that would otherwise be forfeited, shall become fully vested. Furthermore, any account the Executive
may have under the DICP shall be credited with the matching contributions that would have been made on behalf of Executive under the DICP had Executive continued to defer salary under the DICP at the rate in effect as of the date of such termination
for an additional twenty-four (24) months. Notwithstanding anything contained herein, Executive’s accounts under the DICP and/or SDP shall be paid to Executive at such time and in such form as otherwise payable under the terms of the DICP
and/or SDP, as applicable 
 14. Section 4.6 of the Agreement is amended to add the following to the end thereof. 
 Notwithstanding anything contained in this Section 4.6, in no event shall Executive become entitled to any indemnity, payment or
benefit in respect of any taxes, interest or penalties under Section 409A of the Code arising out of, or in connection with, or otherwise related to any payment to which Executive may become entitled due to the changes effected by this
Amendment (other than the amendments to Sections 3.5(c), 4.2(d) or 4.5(d)); provided, however, that this sentence shall not reduce or eliminate any right to indemnity relating to 409A except to the extent resulting from changes effected by this
Amendment (other than the amendments to Sections 3.5(c), 4.2(d) or 4.5(d)). Based on the information and legal analysis of which the Parties are currently aware, the Parties agree that the Company is not required, nor does it intend, to withhold any
Section 409A taxes from any such payments nor report any amounts as subject to Section 409A taxes on Executive’s Form W-2. 
 Any payments made pursuant to the Agreement will be reduced by normal required income and employment tax withholding and will be reported as income on the Executive’s Form W-2 for the year in which payment
occurs. To the extent that the payments constitute excess parachute payments under Section 280G and if Executive is entitled to be grossed-up for the excise taxes related thereto, the Company shall: (1) pay all of the excise taxes owed
with respect to the payment no later than on the business day following the date of payment, (2) impute such taxes paid into the income of Executive,

and (3) pay all taxes related to such income imputation no later than on the business day following the date of payment. As a result of the foregoing
tax payments by the Company, the payment made to Executive will not be reduced by any such excise taxes or additional taxes on the imputed income. The Company shall report such additional income and the total amount of taxes paid on Executive’s
Form W-2 for the year of payment. Any other gross-up payment to which Executive is entitled under this Agreement will be paid at the time when the relevant tax is due. For the avoidance of doubt, this second paragraph of Section 13 of this
Amendment shall not operate to reduce or eliminate any gross-up payment to which Executive is entitled under Section 4.6, but merely clarifies the timing of such payments. 
 14. Except as expressly amended hereby, the Agreement shall remain in full force and effect.
