Amended and Restated Employment Agreement



 Exhibit 10(a) 
 AMENDED AND RESTATED EMPLOYMENT AGREEMENT 
 This AMENDED AND
RESTATED EMPLOYMENT AGREEMENT (the “Agreement”) dated October 17, 2011 is made by and between ENERGY FUTURE HOLDINGS CORP. (the “Company”) and JOHN YOUNG (“Executive”)
(individually, each a “Party” and collectively, the “Parties”). 

WITNESSETH 
 WHEREAS, the Parties previously entered into an employment agreement dated January 6, 2008 and effective January 31, 2008 (“Original Effective Date”); and

 WHEREAS, the Parties desire to amend and restate the employment agreement, in each case on the terms and conditions
set forth herein. 
 NOW, THEREFORE, in consideration of the mutual promises, covenants and obligations contained herein,
the 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 July 1, 2011 (“Effective Date”) and shall end as of 11:59:59 P.M. on June 30, 2015 (the “Initial
Term”). Subject to the provisions of Section 7 of this Agreement, 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. Position and Duties. 
 (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 (as used herein, the term “Board” shall mean the board of directors of
the Company or a committee designated by such board), 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 shall be customary for Executive’s position in a business of similar size, type and nature to that of the Company. Executive shall be the senior most executive officer of the Company and 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 performance of the duties described in Section 2(a) and will not engage in any other business, profession or occupation for compensation or otherwise which would conflict or interfere, directly or indirectly,
with performance of Executive’s duties; provided, however, that nothing herein shall preclude Executive from participating in civic and charitable activities and boards and from serving on the outside board of directors of one other


  
 1 








 
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 or corporation; 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 of $1,200,000
annually, payable in regular installments in accordance with the Company’s usual payment practices. Executive may be entitled to increases in his base salary in the sole discretion of the Board, which shall make such determinations following
its 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 fiscal year during the Employment Term, Executive shall have the
opportunity to earn an annual bonus award (the “Annual Bonus”) pursuant to the terms and conditions of the EFH Executive Annual Incentive Plan (“AIP”) of 100% of Base Salary (“Target
Award”). The amount of the Annual Bonus shall be based upon the achievement of annual business performance targets and Executive’s individual performance, both as approved by the Board; provided, however, if the Company and/or
Executive achieve superior performance targets as established by the Board, then Executive shall be eligible to receive a bonus award constituting 200% of his Target Award. Each Annual Bonus, if any, shall be paid to Executive within two and
one-half (2 1/2) months after the end of the
applicable fiscal year. 
 5. Employee Benefits; Perquisites; Fringe Benefits. 

(a) Welfare, Savings and Retirement Benefits. During the Employment Term, Executive shall be entitled to participate in the
Company’s group health, life, disability, and all tax qualified and nonqualified benefit plans, as in effect from time to time (collectively “Employee Benefits”), on a basis which is no less favorable than is offered to
other members of the Strategy and Policy Committee, to the extent consistent with applicable law and the terms of the applicable plans. 
 (b) Fringe Benefits; Perquisites. During the Employment Term, Executive shall be entitled to fringe benefits and perquisites consistent with the practices of the Company (including, without
limitation, the Company’s payment on behalf of Executive of monthly dues of a country club selected by Executive) to the extent the Company provides similar benefits or perquisites (or both) to other members of the Strategy and Policy Committee
and Executive is otherwise eligible to participate. 
 (c) At the beginning of each calendar year during the Employment Term,
Executive shall be entitled to the greater of: five (5) weeks of paid vacation, or the maximum number of days Executive is entitled to under the Company’s vacation or paid time off policy, as applicable. Executive shall be entitled to
carry over up to five (5) days of unused vacation from one calendar year to the next; provided that, any carryover vacation days not used in the next calendar year shall be forfeited. Executive shall also be entitled to paid sick leave benefits
in accordance with those provided to other similarly situated executives during the Employment Term. 

  
 2 








 (d) Executive shall be entitled to the additional benefits and compensation set forth in
Exhibits I and II attached hereto, subject to the terms and conditions thereof. 
 6. Business Expenses. Subject
to the Company’s standard policies and procedures with respect to expense reimbursement, the Company shall reimburse Executive for, or pay on behalf of Executive, reasonable and appropriate expenses incurred by Executive for business related
purposes, provided claims for reimbursement are submitted timely and with appropriate supporting documentation. 
 7.
Termination. Executive’s employment hereunder may be terminated by either the Company or 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 termination of Executive’s employment. Notwithstanding the foregoing, the Company may, in lieu of providing sixty (60) days advance written notice of termination, immediately
terminate Executive’s employment for Cause; provided, that, the Company provides Executive with the compensation and benefits then in effect at the time of such termination to which Executive would have been entitled had he continued employment
with the Company for such sixty (60) day period. The provisions of this Section 7 shall exclusively govern Executive’s rights upon termination of employment with the Company and its Affiliates (as defined in Section 8(c) below).

 (a) By the Company for Cause or by Executive Due to Voluntary Resignation without Good Reason. 

(i) Executive’s employment may be terminated by the Company for Cause (as defined below) or by Executive’s voluntary
resignation without Good Reason (as defined below) and, in either case, Executive shall be entitled to receive: 
 (A) within
six (6) calendar days following the date of termination, accrued, but unpaid Base Salary and unused vacation, earned through the date of termination; 
 (B) in accordance with Section 4 (except to the extent payment is otherwise deferred pursuant to any applicable deferred compensation arrangement with the Company), any accrued but unpaid Annual
Bonus earned for any previously completed fiscal year; 
 (C) within sixty (60) days of Executive’s claim for
reimbursement, payment 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 that claims for reimbursement are accompanied by
appropriate supporting documentation and are submitted to the Company within ninety (90) days following the date of Executive’s termination of employment; 

  
 3 








 (D) Employee Benefits and equity compensation, if any, as to which Executive may be
entitled under the employee benefit plans of the Company and its Affiliates or any agreement between the Company (and/or its Affiliates) and Executive; and 
 (E) any amounts payable or that may become payable pursuant to Section 7(g) and/or Section 9(g) (the amounts described in clauses (A) through (E) hereof being referred to as the
“Accrued Rights”). 
 Following 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) and for any rights to indemnification and claims for liability insurance coverage under officer and director policies, Executive shall have no further
rights to any compensation or any other benefits under this Agreement. 
 (ii) For purposes of this Agreement, the terms:

 (A) “Cause” shall mean (i) if, in carrying out his duties to the Company, 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 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, provided that Executive has not previously given the Company his written consent, (i) a reduction in Executive’s Base Salary or
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 proportionately); (ii) a transfer of
Executive’s primary workplace by more than fifty (50) miles from the workplace on the Effective Date; (iii) a substantial adverse change in Executive’s title, duties or responsibilities; (iv) any material breach of this
Agreement; or (v) an adverse change in Executive’s reporting responsibilities 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 Executive gives the Company written notice of any such event set forth above, shall not constitute Good Reason. 
 (b) Disability or Death. 
 (i) Executive’s employment shall terminate
upon Executive’s death and may be terminated by the Company if Executive has a Disability (as defined below) and, in either case, Executive or Executive’s estate (as the case may be) shall be entitled to receive: 

(A) the Accrued Rights; 
 (B) a portion of the Target Award that Executive would have been entitled to receive pursuant to Section 4 hereof for the fiscal year of termination, such portion to be determined by multiplying the
Target Award by a fraction, the numerator of which 

  
 4 








 
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; and 
 (C) any additional benefits and compensation set forth in Exhibits I and II attached hereto, subject to the terms and conditions thereof. 
 Following Executive’s termination of employment due to death or Disability, except as set forth in this Section 7(b)(i) and for any rights to indemnification and claims for liability insurance
coverage under officer and director policies, 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, with reasonable accommodation, 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 inability to
perform such duties due to a mental or physical incapacity which is, or is reasonably expected to become, a long-term disability, then Executive’s employment shall not be deemed terminated by the Company and Executive shall not be able to
resign with Good Reason. Any question as to the existence of a Disability 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 on 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. 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 and, in either case (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 the
Company and its Affiliates (excluding claims for indemnification, claims for coverage under officer and director policies, and claims as a stockholder of the Company): 
 (A) a lump sum payment equal to: (I) three (3) times Executive’s Base Salary, and (II) the Pro-Rata Bonus, payable as soon as practicable but no later than the earlier of:
(a) March 15 following the calendar year in which termination occurs or (b) ninety (90) days following termination; and 

  
 5 








 (B) 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) thirty (30) months 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 (determined on a coverage by coverage and benefit by benefit basis) under the group health plans of a subsequent employer. If Executive continues to receive benefits pursuant to this Section 7(c)(ii)(B)
when, in the absence of the benefits provided in this Section 7(c)(ii)(B), Executive would not 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 no later than the end of the calendar year immediately following the calendar year in which the applicable expenses were incurred. The health care continuation coverage period under the
Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), Code Section 4980B, or any replacement or successor provision of United States tax law, shall run concurrently with the Severance Period; and

 (iii) any additional benefits and compensation set forth in Exhibits I and II attached hereto, subject to the terms and
conditions thereof. 
 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) and for any rights to indemnification and claims for liability
insurance coverage under officer and director policies, Executive shall have no further rights to any compensation or any other benefits under this Agreement. 
 (d) Expiration of Employment Term. 
 (i) In the event Executive elects not
to extend the Employment Term pursuant to Section 1 and Executive’s employment has not been earlier terminated pursuant to Sections 7(a), (b), (c), or (e), the Employment Term shall expire and Executive’s employment hereunder shall
terminate as of the end of the day immediately preceding the commencement of a subsequent Renewal Term, and Executive shall be entitled to receive the Accrued Rights. Except as set forth in this Section 7(d)(i) and for any rights to
indemnification and claims for liability insurance coverage under officer and director policies, Executive shall have no further rights to any compensation or any other benefits under this Agreement. 

(ii) In the event the Company elects not to extend the Employment Term pursuant to Section 1 and Executive’s employment has
not been earlier terminated pursuant to Sections 7(a), (b), (c), or (e), the Employment Term shall expire and Executive’s employment hereunder shall terminate as of the end of the day immediately preceding the commencement of a subsequent
Renewal Term, and Executive shall be entitled to receive the payments and benefits applicable to a termination of Executive’s employment without Cause pursuant to Section 7(c) or Section 7(e), as applicable. Except as set forth in
this Section 7(d)(ii) and for any rights to indemnification and claims for liability insurance coverage under officer and director policies, Executive shall have no further rights to any compensation or any other benefits under this Agreement.

 (e) Change in Control. Notwithstanding any provision contained herein, if
Executive’s employment is terminated by the Company without Cause (other than by reason of death or Disability) or if Executive resigns for Good Reason, in either case, within twenty-four (24) months following a Change in Control (as
defined in the 2007 Stock Incentive Plan for Key Employees of Energy Future Holdings Corp. and its Affiliates), 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 the Company and its Affiliates (excluding claims for indemnification, claims for coverage under
officer and director policies, and claims as a stockholder of the Company), a lump sum payment equal to three (3) times the sum of Executive’s annualized Base Salary and Executive’s Target Award, payable as soon as practicable but no
later than the earlier of: (i) March 15 following the calendar year in which termination occurs or (ii) ninety (90) days following termination; 
 (iii) 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
the Company and its Affiliates (excluding claims for indemnification, claims for coverage under officer and director policies, and claims as a stockholder of the Company), 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 (A) 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 (B) until Executive is, or becomes, eligible for comparable coverage (determined on a coverage by coverage
and benefit by benefit basis) under the group health plans of a subsequent employer. If Executive continues to receive benefits pursuant to this Section 7(e)(iii) when, in the absence of the benefits provided in this Section 7(e)(iii)
Executive would not be entitled to continuation coverage under Code Section 4980B, Executive shall receive reimbursement for all medical expenses no later than the end of the calendar year immediately following the calendar year in which the
applicable expenses were incurred. The health care continuation coverage period under COBRA, Code Section 4980B, or any replacement or successor provision of United States tax law, shall run concurrently with the Severance Period; and

 (iv) any additional benefits and compensation set forth in Exhibits I and II attached hereto, subject to the terms and
conditions thereof. 
 Following Executive’s termination of employment without Cause (other than by reason of Executive’s death or
Disability) or upon Executive’s resignation for Good Reason, in either case, within twenty-four (24) months following a Change in Control, except as set forth in this Section 7(e) and for any rights to indemnification and claims for
liability insurance coverage under officer and director policies, Executive shall have no further rights to any compensation or any other benefits under this Agreement. 

  
 7 








 (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 in accordance with Section 9(j) hereof. For purposes of this Agreement, a “Notice of
Termination” shall mean a notice indicating 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. 
 (g) Code Section 4999. 

(i) If, by reason of, or in connection with, any transaction that occurs after the Original Effective Date, Executive would be subject
to the imposition of the excise tax imposed by Code Section 4999 related to Executive’s employment with the Company, whether before or after termination of Executive’s employment, but the imposition of such tax could be avoided by
approval of shareholders described in Code Section 280G(b)(5)(B), then Executive may ask the Company to seek such approval, in which case the Company 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 Code Section 4999. If Executive fails to request that the Company seek such approval, or if Executive does request that the
Company seek such approval, but fails to cooperate and execute such waivers as may be necessary in the approval process, Section 7(g)(ii) shall not apply and Executive shall not be entitled to any gross-up payment for any resulting tax under
Code Section 4999. If such approval, even if sought and obtained, would not avoid imposition of the excise tax imposed under Code Section 4999, then the provisions of Section 7(g)(ii) shall apply without any precedent obligation of
Executive to seek such approval. 
 (ii) Gross-Up Payment. 

(A) In the event it shall be determined that any payment, benefit or distribution (or combination thereof) by the Company, any
Affiliate, or one or more trusts established by the Company or any Affiliate 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 Code Section 4999 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 federal, state and local income taxes and employment 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. 

  
 8 








 (B) All determinations required to be made under this Section 7(g)(ii), 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, Alvarez & Marsal, or such other
nationally recognized 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 Section 7(g)(ii), 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 Section 7(g)(ii)(C)). As a result of the uncertainty in the application of Code Section 4999, 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 Section 7(g)(ii)(C) 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). 
 (C) 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 he 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 

  
 9 








 
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 Section 7(g)(ii)(C), 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. 

(D) If, after the receipt by Executive of an amount paid or advanced by the Company pursuant to this Section 7(g)(ii), 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 Section 7(g)(ii)(C)) 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 Section 7(g)(ii)(C), a determination is made that Executive shall not be
entitled to any 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 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. 

(E) For the avoidance of doubt, all payments to or for the benefit of Executive provided for in this Section 7(g)(ii) 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.

 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, the Sponsor Group, or any of their respective Affiliates, except when
required to perform his duties to the Company or one of its Affiliates, or by law or judicial process, provided that Executive gives the Company reasonable notice of any legal or judicial proceeding requiring Executive to disclose Confidential
Information and an opportunity to challenge the disclosure of any such information, and Executive agrees to provide such reasonable notice in writing to: 
 General Counsel 
 Energy Future Holdings Corp. 

1601 Bryan Street, 41st Floor 
 Dallas, Texas 75201 
 (214) 812-5153 (facsimile); 

(ii) at any time during the Employment Term and for a period of twenty-four (24) 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 Texas Energy Future
Holdings Limited Partnership, the Company or any of their respective subsidiaries operates or conducts business; or 
 (iii) at
any time during the Employment Term and for a period of twenty-four (24) 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 the Company or any of its subsidiaries in any geographic area where they operate. Notwithstanding the foregoing, for the purposes of this Section 8(a),
(A) Executive may, directly or indirectly own, solely as an investment, securities of any Person engaged in the business of the Company or its Affiliates that 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) Section 8(a)(ii) shall not be violated by reason of any exercise of tag-along rights under the Sale Participation Agreement, by and between the Company (and related parties) and Executive (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 

  
 11 









 
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). Notwithstanding the
foregoing, in the event Executive breaches the covenants set forth in this Section 8, the Company’s rights and remedies with respect Executive’s Options, Option Stock, and Stock and payments related thereto, as those terms are defined
in the Management Stockholder’s Agreement, by and between the Company (and related parties) and Executive (the “Management Stockholder’s Agreement”) shall be limited to those set forth in Section 22(c) of the

as a consequence of or through his employment with the Company or any Affiliate; (B) not publicly available or not generally known outside the Company or any Affiliate; and (C) that relates to the business and/or development of the Company

detrimental to the interests of the Company or any Affiliate; information regarding the Company’s or any Affiliate’s business operations, such as financial and sales data (including budgets, forecasts, and historical financial data),

Executive conceived or developed during his employment with the Company or an Affiliate or learned from other employees or contractors of the Company or an Affiliate that meets the definition of Confidential Information shall be treated as such.

 (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). 
 (v) “Restricted

 (vi) “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. 
 (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, provided that the assignee expressly assumes all obligations of the Company under this Agreement and all other related agreements to which Executive and the
Company are parties. 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. 

  
 13 









 (f) Set Off; Mitigation. Except as otherwise provided in Section 9(o), the
obligations of the Company 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 and/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 and, except as expressly provided herein, no amount payable hereunder shall be reduced by any payments or benefits
received from such subsequent employment. 
 (g) Compliance with Code Section 409A. Notwithstanding anything herein
to the contrary, if, at the time of Executive’s termination of employment, the Company has securities that are publicly traded on an established securities market, and Executive is a “specified employee” (as defined in Code
Section 409A), and the deferral of the commencement of any payments or benefits otherwise payable pursuant to Section 7 is necessary in order to prevent any accelerated or additional tax under Code Section 409A, then, to the extent
permitted by Code Section 409A, the Company will defer any such payments or benefits hereunder (without any reduction in the 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 Code Section 409A), provided that amounts which do not exceed the limits set forth in Code Section 402(g)(1)(B) in the year of such
termination shall be payable immediately upon termination. Any payments or benefits deferred due to such requirements 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 and
its subsidiaries shall indemnify and hold Executive harmless for all acts and omissions occurring during his employment or service as a member of the board of directors or managers (as applicable) of any of the Company and/or its subsidiaries, to
the maximum extent provided under each of the Company’s and such subsidiaries’ charter, certificate of formation, limited partnership agreement, by-laws and applicable law. During the Employment Term and for a term of six (6) years
thereafter, the Company, or any successor to the Company, the Company’s subsidiaries (to the extent not covered under the terms of the Company’s insurance policy), and each of their respective successors, shall purchase and maintain, at
their own expense, directors’ and officers’ liability insurance providing coverage for Executive in the same amount as, and with terms no less favorable than, for members of their respective boards of directors or managers (as applicable).

 (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. In the event of Executive’s death before receiving all amounts and benefits due to him hereunder, such amounts shall be payable to
Executive’s estate or as otherwise provided under applicable benefit plans or arrangements.

 Exhibit I 
 In addition to the benefits, perquisites and compensation set forth in the Agreement, Executive shall be entitled to receive the benefits, perquisites and compensation set forth in this Exhibit I, subject
to the terms and conditions set forth herein: 
 (a) Executive shall have the opportunity to earn the retention awards set forth
in this Exhibit I, collectively referred to herein as the “Retention Award”, subject to the terms and conditions set forth herein: 
 (i) Executive shall earn a long-term cash bonus award equal to 100% of the aggregate Annual Bonus amount actually earned by Executive in respect of fiscal years 2009, 2010, and 2011 (the “First
Retention Award”). The First Retention Award earned by Executive shall be paid to Executive in a lump sum on September 30, 2012; provided, that, subject to the provisions of sub-paragraph (a)(v) of this Exhibit I, Executive is
employed by the Company or an Affiliate thereof on September 30, 2012. 
 (ii) Executive shall earn an additional
long-term cash bonus award in an amount between $750,000 and $1,500,000 determined by the Company’s performance as indicated by the level of EFH Management EBITDA actually achieved for the fiscal year ended December 31, 2011 relative to
the EFH Management EBITDA threshold and target amounts set by the Board for such fiscal year (the “Second Retention Award”). For the achievement of the threshold level of EFH Management EBITDA in respect of such year,
Executive shall earn $750,000, for the achievement of at least the target level of EFH Management EBITDA in respect of such year, Executive shall earn $1,500,000 (the “Second Retention Target Award”), and for the achievement
of EFH Management EBITDA in between the threshold and target levels in respect of such year, Executive shall earn an amount between $750,000 and $1,500,000 as determined by linear interpolation. The Second Retention Award, if earned, shall be paid
to Executive in two equal installments on September 30, 2012 and September 30, 2013; provided, that, subject to the provisions of sub-paragraph (a)(v) of this Exhibit I, Executive is employed by the Company or an Affiliate thereof on the
applicable payment date. 
 (iii) Executive shall earn an additional long-term cash bonus award in an amount between $1,350,000
and $2,700,000 per fiscal year determined by the Company’s performance as indicated by the level of EFH Management EBITDA actually achieved for the fiscal years ended December 31, 2012, December 31, 2013, and December 31,
2014 relative to the EFH Management EBITDA threshold and target amounts set by the Board for each respective fiscal year (the “Third Retention Award”). For the achievement of the threshold level of EFH Management EBITDA in
respect of any such year, Executive shall earn $1,350,000, for the achievement of at least the target level of EFH Management EBITDA in respect of any such year, Executive shall earn $2,700,000 (the “Third Retention Target
Award”), and for the achievement of EFH Management EBITDA in between the threshold and target levels in respect of any such year, Executive shall earn an amount between $1,350,000 and $2,700,000 as determined by linear interpolation.
The Third Retention Award, if earned, shall be paid to Executive in a lump sum on March 13, 2015; provided, that, subject to the provisions of sub-paragraph (a)(v) of this Exhibit I, Executive is employed by the Company or an Affiliate thereof
on March 13, 2015. 

  
 Exhibit I-1









 (iv) The process followed by the O&C Committee in establishing the EFH Management
EBITDA threshold and target amounts for purposes of the Second Retention Award and the Third Retention Award shall be consistent with the O&C Committee’s prior practice. 

(v) In the event Executive’s employment is terminated pursuant to Section 7(b), 7(c), 7(d)(ii), or 7(e) hereof, in any case,
prior to the payment date of an applicable Retention Award, Executive shall be entitled to receive the Retention Award, or a portion thereof, that Executive would otherwise have been entitled to receive pursuant to sub-paragraphs (a)(i), (a)(ii),
and (a)(iii) of this Exhibit I, calculated as set forth below (the sum of such amounts referred to herein as the “Pro-Rata Retention Award”), with such Pro-Rata Retention Award payable to Executive as soon as practical but no
later than the earlier of: (a) March 15 following the calendar year in which termination occurs or (b) ninety (90) days following termination; provided, that, in the case of a termination of employment pursuant to Section 7(c),
7(d)(ii), or 7(e), 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 the Company and its Affiliates (excluding
claims for indemnification, claims for coverage under officer and director policies, and claims as a stockholder of the Company). 
 (A) with respect to the First Retention Award, (x) 100% of the aggregate Annual Bonus amount(s) actually earned by Executive in respect of any applicable fiscal year completed prior to the date of
Executive’s termination, plus (y) if the termination occurs prior to January 1, 2012, 100% of the Pro-Rata Bonus amount calculated pursuant to Section 7(b)(i)(B) above (for avoidance of doubt, the First Retention Award payment
shall not be based on any Annual Bonus or Pro-Rata Bonus earned by or paid to Executive with respect to fiscal year 2012); plus 
 (B) with respect to the Second Retention Award, (x) if the termination occurs prior to January 1, 2012, a portion of the Second Retention Award to be determined by multiplying the Second
Retention Target Award by a fraction, the numerator of which is the number of days during which Executive was employed by the Company or an Affiliate thereof in the fiscal year of Executive’s termination, and the denominator of which is 365, or
(y) if the termination occurs on or after January 1, 2012, the actual earned amount of the Second Retention Award; plus 
 (C) with respect to the Third Retention Award, (x) if the termination occurs prior to January 1, 2015, a portion of the Third Retention Award equal to (1) the amount that would have been
payable under sub-paragraph (a)(iii) of this Exhibit I for any completed fiscal year, plus (2) a portion of the Third Retention Award to be determined by multiplying the Third Retention Target Award for the year of Executive’s termination
by a fraction, the numerator of which is the number of days during which Executive was employed by the Company or an Affiliate thereof in the fiscal year of Executive’s termination, and the denominator of which is 365, or (y) if the
termination occurs on or after January 1, 2015, the actual earned amount of the Third Retention Award. 
 (vi)
Notwithstanding any provision of this Exhibit I to the contrary, in the event of a Change in Control, Executive’s entitlement to the Retention Awards shall be 

  
 Exhibit I-2









 
determined without regard to the achievement of EFH Management EBITDA in respect of the fiscal year in which such Change in Control occurs and any subsequent year, and the amount earned by
Executive shall be determined as if target level of EFH Management EBITDA were achieved for any such year, but to the extent the Retention Award is attributable to any prior fiscal year, actual EFH Management EBITDA for such prior year shall be
used. 
 (vii) To assure payment of the Company’s obligations under sub-paragraphs (a)(ii) and (a)(iii) above, the Company
shall obtain the issuance of an Irrevocable Standby Letter of Credit (the “LOC”) for the benefit of Executive from a bank (the “Issuer”) on the following terms: 

(A) The LOC shall be in the amount of $9,600,000. 
 (B) The LOC shall expire on                    . 

(C) The LOC shall not be transferable. 
 (D) Partial and multiple draws shall be permitted under the LOC. [Information Omitted] 
 (viii) The LOC shall be issued in the form attached hereto as Exhibit I(A) as soon as administratively feasible after the date of this Agreement. 

(ix) Any amount paid under the LOC to the United States Treasury in respect of the Company’s tax account shall be credited as
withheld income and payroll taxes with respect to Executive, and the Company shall properly report such amount on IRS Form W-2 issued to Executive for the applicable tax year. 

(x) For purposes hereof, “EFH Management EBITDA” shall mean Energy Future Holdings Corp. consolidated EBITDA;
where: 
 (A) “EBITDA” shall mean earnings before interest, taxes, depreciation and amortization plus
transaction, management and/or similar fees paid to the Sponsor Group and/or its Affiliates, together with such adjustments as the O&C Committee shall determine appropriate in its discretion after good faith consultation with the Chief Executive
Officer and/or Chief Financial Officer. Such adjustments will be consistent with those included in the definition of EBITDA in the Energy Future Holdings Corp. Indenture related to its 10.000% Senior Secured Notes due 2020, as such indenture is in
effect on the Effective Date, to the extent considered appropriate for management compensation purposes, which will include but are not limited to, adjustments to reflect unrealized mark-to-market valuations of hedging instruments; fees and expenses
relating to the Company’s receivables financing facilities; the amortization of nuclear fuel costs; and any effects of adjustments in the financial statements resulting from the application of purchase accounting; but which for clarification
will not include, without limitation, adjustments to reflect unrealized cost savings and planned and unplanned outages. In any event and notwithstanding anything herein to the contrary, the O&C Committee shall have the discretion to make any
further adjustments to the calculation of EBITDA as it deems fair and appropriate after good faith consultation with the Chief Executive Officer and/or Chief Financial Officer. 

  
 Exhibit I-3









 (B) The O&C Committee shall, fairly and appropriately, following the O&C
Committee’s good faith consultation with the Chief Executive Officer and/or Chief Financial Officer, adjust the calculation of EBITDA to reflect the following: acquisitions, divestitures, any change required by GAAP relating to share-based
compensation or for other changes in GAAP promulgated by accounting standard setters that, in each case, the O&C Committee in good faith determines require adjustment of EBITDA. The O&C Committee’s determination of such adjustment shall
be based on the effect of such event on the Company’s consolidated financial statements. 
 (b) As soon as administratively
practicable following the February O&C Committee meeting in each of 2011, 2012, and 2013, provided Executive remains continuously employed by the Company or an Affiliate thereof through each applicable grant date, Executive shall be entitled to
receive on each such date, a grant of 1,500,000 restricted stock units under the 2007 Stock Incentive Plan for Key Employees of Energy Future Holdings Corp. and its Affiliates and the Restricted Stock Unit Agreement, in such form and substance as
attached hereto as Exhibit I(B), to be entered into by and between the Company and Executive with respect to each annual grant. In the event of a Change in Control prior to any applicable grant date, the restricted stock units that would have been
granted under this sub-paragraph (b) of this Exhibit I shall be issued and shall be vested immediately prior to the effective date of the Change in Control. The rights and obligations of Executive and the Company shall be governed by the 2007
Stock Incentive Plan for Key Employees of Energy Future Holdings Corp. and its Affiliates and the Restricted Stock Unit Agreement entered into incident to each such grant.

 Exhibit I(B) 
 2007 STOCK INCENTIVE PLAN FOR KEY EMPLOYEES OF 
 ENERGY FUTURE HOLDINGS
CORP. AND ITS AFFILIATES 
 RESTRICTED STOCK UNIT AGREEMENT 

 

					
	To: [Name]	  	Date of Grant: [Date]	  	Number of Shares: [#]

 This Agreement is made and entered into as of the Date of Grant set forth above by and between Energy
Future Holdings Corp., a Texas corporation (the “Company”), and you; 
 WHEREAS, the Company
adopted the 2007 Stock Incentive Plan for Key Employees of Energy Future Holdings Corp. and its Affiliates, as it may be amended from time to time (the “Plan”) under which the Company is authorized to grant restricted stock
units to certain employees, directors and other service providers of the Company or a Subsidiary; 
 WHEREAS, a
“Restricted Stock Unit” shall represent your right to receive one share of common stock of the Company (the “Stock”) upon the lapse of the restrictions on your award, plus the additional rights to
receive dividend equivalents (“Dividend Equivalent Right,” or “DER”), in accordance with the terms and conditions set forth herein and in the Plan (the “Award”); 

WHEREAS, a copy of the Plan has been made available to you and shall be deemed a part of this Restricted Stock Unit Agreement
(“Agreement”) as if fully set forth herein; and 
 WHEREAS, you desire to accept the Award made
pursuant to this Agreement. 
 NOW, THEREFORE, in consideration of the mutual covenants set forth herein and for other
valuable consideration hereinafter set forth, you and the Company agree as follows: 
 1. The Grant. Subject to the
conditions set forth below, the Company hereby grants you, effective as of the Date of Grant set forth above, an award consisting of [#] Restricted Stock Units (subject to any adjustment made to this Award pursuant to Section 8 of
the Plan in connection with a stock split, spin-off, recapitalization or other transaction that affects the Company’s equity securities). To the extent that any provision of this Agreement conflicts with the expressly applicable terms of the
Plan, you acknowledge and agree that those terms of the Plan shall control and, if necessary, the applicable terms of this Agreement shall be deemed amended so as to carry out the purpose and intent of the Plan. Terms that have their initial letter
capitalized, but that are not otherwise defined in this Agreement shall have the meanings given to them in the Plan. 
 2. No
Shareholder Rights. The Restricted Stock Units granted pursuant to this Agreement do not and shall not entitle you to any rights of a holder of Stock prior to the date shares of Stock are issued to you in settlement of the Award. Your rights
with respect to the Restricted Stock Units shall remain forfeitable at all times prior to the date on which rights become vested and the restrictions with respect to the Restricted Stock Units lapse in accordance with Section 6 or 7, as the
case may be. 

  
 Exhibit I(B)-1









 3. Dividend Equivalent Rights. In the event that the Company declares and pays a
dividend in respect of its outstanding shares of Stock and, on the record date for such dividend, you hold Restricted Stock Units granted pursuant to this Agreement that have not been settled, the Company shall create a bookkeeping account that will
track, (a) to the extent the dividend paid to stockholders generally was a cash dividend, the cash value you would have been entitled to receive as if you had been the holder of record of the number of shares of Stock related to the Restricted
Stock Units that have not been settled as of the record date, or (b) to the extent the dividend paid to stockholders generally was paid in the form of property, the property you would have been entitled to receive as if you had been the holder
of record of the number of shares of Stock related to the Restricted Stock Units that have not been settled as of the record date. All DER amounts credited to your bookkeeping account pursuant to this Section 3, if any, shall be deemed
converted into shares of Stock on the date that the Restricted Stock Units vest (based on the Fair Market Value (as such term is defined in the Management Stockholder’s Agreement) of Stock on such date and rounded down to the nearest whole
share of Stock) and paid to you in the form of additional shares of Stock on the date that the underlying Restricted Stock Units associated with such DER amounts are settled pursuant to Section 5 below. In the event that the Restricted Stock
Units are forfeited to the Company without settlement to you, you will also forfeit any associated DER amounts. No interest will be payable with respect to DER amounts credited to your bookkeeping account, if any, that represent cash dividends.
Property, if any, deemed credited to DER bookkeeping accounts representing dividends paid in property will be deemed invested in such property until the DER amounts are deemed converted to shares of Stock pursuant to this Section 3. The
bookkeeping accounts, if any, created to track DER amounts are phantom accounts and the Company is under no obligation to set aside cash or property with respect to any DER amounts. Valuations made pursuant to this Section 3 (including any
valuation of property deemed credited to a bookkeeping account) will be made by the Committee, or its designee, in its sole discretion and such valuation will be final and binding. 

4. Restrictions; Forfeiture. The Restricted Stock Units are restricted in that they may not be sold, transferred or otherwise
alienated or hypothecated until these restrictions are removed or expire as contemplated in Section 6 or 7 of this Agreement and Stock is issued to you as described in Section 5 of this Agreement. The Restricted Stock Units are also
subject to forfeiture to the Company (the “Forfeiture Restrictions”) pursuant to Section 7 of this Agreement. 
 5. Issuance of Stock. 
 (a) No shares of Stock shall be issued to you prior
to the date on which the Restricted Stock Units vest and the restrictions, including the Forfeiture Restrictions, with respect to the Restricted Stock Units lapse, in accordance with Section 6 or 7. After the Restricted Stock Units vest
pursuant to Section 6 or 7, as applicable, the Company shall, subject to any conditions described in subsection (b) below, promptly and within 30 days of such vesting date, cause to be issued Stock registered in your name in payment of
such vested Restricted Stock Units upon receipt by the Company of any required tax withholding. Such issuance shall be made as soon as administratively practicable, but may be delayed, in the sole discretion of the Committee, if required by
applicable securities law; provided, that, in no event shall the issuance of Stock be made later than March 15th of the year following the year of vesting, or as otherwise may be permitted under Treasury Regulation
§ 1.409A-1(b)(4)(ii). The Company shall evidence 

  
 Exhibit I(B)-2









 
the Stock to be issued in payment of such vested Restricted Stock Units in the manner it deems appropriate. The value of any fractional Restricted Stock Units shall be rounded down at the time
Stock is issued to you in connection with the Restricted Stock Units. No fractional shares of Stock, nor the cash value of any fractional shares of Stock, will be issuable or payable to you pursuant to this Agreement. The value of such shares of
Stock shall not bear any interest owing to the passage of time. Neither this Section 5 nor any action taken pursuant to or in accordance with this Section 5 shall be construed to create a trust or a funded or secured obligation of any
kind. 
 (b) You hereby acknowledge that by accepting this Award, the issuance of Stock pursuant to the settlement of your
Restricted Stock Units pursuant to this Agreement shall be subject to all the terms and conditions of any Management Stockholder’s Agreement and Sale Participation Agreement previously executed by you, as such forms may be modified under the
terms of such agreements; provided, however, that if you have not previously executed a Management Stockholder’s Agreement and/or a Sale Participation Agreement with the Company, you agree that, prior to the Company’s issuance of Stock to
you pursuant to this Agreement, you will execute such documents in the form required by the Company. All Stock issued to you pursuant to this Agreement will (a) constitute “Stock” (as such term is defined in the Management
Stockholder’s Agreement) for all purposes under the Management Stockholder’s Agreement, and (b) be treated as “Common Stock” underlying “Options” (as such terms are defined in the Sale Participation Agreement) for
all purposes under the Sale Participation Agreement. 
 (c) The shares of Stock deliverable upon vesting of the Restricted Stock
Units, may be either previously authorized but unissued shares or issued shares, which have then been reacquired by the Company. Such shares shall be fully paid and nonassessable. 

6. Expiration of Restrictions and Risk of Forfeiture. Unless otherwise provided in Section 7 below, the restrictions on the
Restricted Stock Units granted pursuant to this Agreement, including the Forfeiture Restrictions, will expire on September 30, 2014, and shares of Stock that are nonforfeitable and transferable will be issued to you in payment of your vested
Restricted Stock Units as set forth in Section 5, provided that you remain in the continuous employ of, or a service provider to, the Company or its Subsidiaries until September 30, 2014. 

7. Termination of Services or Change in Control Events. 
 (a) Termination of Employment Other Than without Cause, for Good Reason, or Due to Death or Disability. In the event your service relationship with the Company or any of its Subsidiaries is
terminated for any reason other than by the Company or any of its Subsidiaries without Cause, by your voluntary resignation for Good Reason, or due to your death or Disability (“Cause”, “Good Reason”, and “Disability”
as defined in your employment agreement with the Company or any of its Subsidiaries then in effect at the time of your termination of employment) prior to September 30, 2014, then those Restricted Stock Units for which the restrictions have not
lapsed as of the date of your termination shall become null and void and those Restricted Stock Units shall be forfeited to the Company. 

  
 Exhibit I(B)-3









 (b) Termination of Employment without Cause, for Good Reason, or Due to Death or
Disability. In the event your service relationship with the Company or any of its Subsidiaries is terminated by the Company or any of its Subsidiaries without Cause, by your voluntary resignation for Good Reason, or due to your death or
Disability prior to September 30, 2014, a portion of the Restricted Stock Units shall vest and all Forfeiture Restrictions shall lapse with respect to such Restricted Stock Units on the effective date of your termination of employment. The
portion of the Restricted Stock Units that shall become vested upon your termination of employment shall be determined by multiplying the number of Restricted Stock Units set forth in Section 1 by a fraction, the numerator of which is the
number of days you were employed by the Company or any of its Subsidiaries from [February    , 20    ] through the effective date of your termination of employment, and the denominator of which is the number
of days between [February     , 20    ] and September 30, 2014; all remaining Restricted Stock Units shall become null and void and shall be forfeited to the Company upon your termination of
employment. The Restricted Stock Units that become vested pursuant to this Section 7(b) will be settled in accordance with Section 5 above. 
 (c) Change in Control. In the event that the Company undergoes a Change in Control (as defined in the Plan) prior to September 30, 2014, the Restricted Stock Units shall vest and all
Forfeiture Restrictions shall lapse on the effective date of such a Change in Control, provided that you have remained in the continuous employ of, or a service provider to, the Company or its Subsidiaries from the Date of Grant until the effective
date of the Change in Control. Upon a Change in Control, your Restricted Stock Units will be settled in accordance with Section 5 above. 
 8. Leave of Absence. With respect to the Award, the Company may, in its sole discretion, determine that if you are on leave of absence for any reason you will not be considered as having terminated
employment with the Company; however, your rights to the Restricted Stock Units during a leave of absence will be limited to the extent to which those rights were earned or vested when the leave of absence began. 

9. Payment of Taxes. It shall be a condition of the obligations of the Company upon delivery of the Stock pursuant to
Section 5 above that you pay to the Company such amount as may be requested by the Company for the purpose of satisfying any liability for any federal, state or local income or other taxes required by law to be withheld with respect to such
Stock. The Company may, in its sole discretion, and you hereby authorize the Company to take such actions as may be necessary, in the opinion of the Company’s counsel (including, without limitation, withholding Stock otherwise deliverable to
you hereunder through a net settlement and/or withholding amounts from any compensation or other amount owing to you from the Company), to satisfy the obligations for payment of the minimum amount of any such taxes. Notwithstanding the foregoing
provisions of this Section 9, you may, at your election, be permitted to elect to use Stock otherwise deliverable to you hereunder, having an equivalent Fair Market Value (as such term is defined in the Management Stockholder’s Agreement)
to the payment that would otherwise be made by you to the Company pursuant to the foregoing provisions of this Section 9, to satisfy such obligations. You are hereby advised to seek your own tax counsel regarding the taxation of the Restricted
Stock Units made hereunder. 

  
 Exhibit I(B)-4









 10. Compliance with Securities Law. Notwithstanding any provision of this Agreement
to the contrary, the issuance of Stock will be subject to compliance with all applicable requirements of federal, state, or foreign law with respect to such securities and with the requirements of any stock exchange or market system upon which the
Stock may then be listed. No Stock will be issued hereunder if such issuance would constitute a violation of any applicable federal, state, or foreign securities laws or other law or regulations or the requirements of any stock exchange or market
system upon which the Stock may then be listed. In addition, Stock will not be issued hereunder unless (a) a registration statement under the Securities Act of 1933, as amended (the “Securities Act”), is, at the time of
issuance, in effect with respect to such shares or (a) in the opinion of legal counsel to the Company, such shares may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act.
YOU ARE CAUTIONED THAT ISSUANCE OF STOCK UPON THE VESTING OF RESTRICTED STOCK UNITS GRANTED PURSUANT TO THIS AGREEMENT MAY NOT OCCUR UNLESS THE FOREGOING CONDITIONS ARE SATISFIED. The inability of the Company to obtain from any regulatory body
having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance and sale of any shares subject to the Award will relieve the Company of any liability in respect of the failure to issue
such shares as to which such requisite authority has not been obtained. As a condition to any issuance hereunder, the Company may require you to satisfy any qualifications that may be necessary or appropriate to evidence compliance with any
applicable law or regulation and to make any representation or warranty with respect to such compliance as may be requested by the Company. From time to time, the Board and appropriate officers of the Company are authorized to take the actions
necessary and appropriate to file required documents with governmental authorities, stock exchanges, and other appropriate Persons to make shares of Stock available for issuance. 

11. Lock-Up Period. You hereby agree that, if so requested by the Company or any representative of the underwriters (the
“Managing Underwriter”) in connection with any registration of the offering of any securities of the Company under the Securities Act, you will not sell or otherwise transfer any Stock acquired hereunder or other
securities of the Company during the 180 day period (or such other period as may be requested in writing by the Managing Underwriter and agreed to in writing by the Company) (the “Market Standoff Period”) following the
effective date of a registration statement of the Company filed under the Securities Act. The Company may impose stop-transfer instructions with respect to securities subject to the foregoing restrictions until the end of such Market Standoff
Period. 
 12. Legends. The Company may at any time place legends referencing any restrictions imposed on the shares
pursuant to Sections 5(b), 10 and 11 of this Agreement on all certificates representing shares issued with respect to this Award. 
 13. Right of the Company and Subsidiaries to Terminate Services. Nothing in this Agreement confers upon you the right to continue in the employ of or to perform services for the Company or any
Subsidiary, or interfere in any way with the rights of the Company or any Subsidiary to terminate your employment or service relationship at any time. 
 14. Furnish Information. You agree to furnish to the Company all information reasonably requested by the Company to enable it to comply with any reporting or other requirements imposed upon the
Company by or under any applicable statute or regulation with respect to the transactions contemplated by this Agreement. 

  
 Exhibit I(B)-5









 15. No Liability for Good Faith Determinations. The Company and the members of the
Board shall not be liable for any act, omission or determination taken or made in good faith with respect to this Agreement or the Restricted Stock Units granted hereunder. 
 16. Execution of Receipts and Releases. Any payment of cash or any issuance or transfer of shares of Stock or other property to you, or to your legal representative, heir, legatee or distributee,
in accordance with the provisions hereof, shall, to the extent thereof, be in full satisfaction of all claims of such Persons hereunder. The Company may require you or your legal representative, heir, legatee or distributee, as a condition precedent
to such payment or issuance, to execute a release and receipt therefor in such form as it shall determine. 
 17. No
Guarantee of Interests. The Board and the Company do not guarantee the Stock of the Company from loss or depreciation. 

18. Company Records. Records of the Company or its Subsidiaries regarding your period of service, termination of service and the
reason(s) therefor, and other matters shall be conclusive for all purposes hereunder, unless determined by the Company to be incorrect. 
 19. Notice. All notices required or permitted under this Agreement must be in writing and personally delivered or sent by mail and shall be deemed to be delivered on the date on which it is
actually received by the person to whom it is properly addressed or if earlier the date it is sent via certified United States mail. 
 20. Waiver of Notice. Any person entitled to notice hereunder may waive such notice in writing. 
 21. Information Confidential. As partial consideration for the granting of the Award hereunder, you hereby agree to keep confidential all information and knowledge, except that which has been
disclosed in any public filings required by law, that you have relating to the terms and conditions of this Agreement; provided, however, that such information may be disclosed as required by law and may be given in confidence to your spouse and
tax, legal and financial advisors. In the event any breach of this promise comes to the attention of the Company, it shall take into consideration that breach in determining whether to recommend the grant of any future similar award to you and as a
factor weighing against the advisability of granting any such future award to you. 
 22. Successors. This Agreement
shall be binding upon you, your legal representatives, heirs, legatees and distributees, and upon the Company, its successors and assigns. 
 23. Severability. If any provision of this Agreement is held to be illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining provisions hereof, but such
provision shall be fully severable and this Agreement shall be construed and enforced as if the illegal or invalid provision had never been included herein. 

  
 Exhibit I(B)-6









 24. Company Action. Any action required of the Company under this Agreement shall be
by resolution of the Board or the Committee or by a person or entity authorized to act by resolution of the Board. 
 25.
Headings. The titles and headings of Sections are included for convenience of reference only and are not to be considered in construction of the provisions hereof. 
 26. Governing Law. All questions arising with respect to the provisions of this Agreement shall be determined by application of the laws of Texas, without giving any effect to any conflict of law
provisions thereof, except to the extent Texas state law is preempted by federal law. The obligation of the Company to sell and deliver Stock hereunder is subject to applicable laws and to the approval of any governmental authority required in
connection with the authorization, issuance, sale, or delivery of such Stock. 
 27. Consent to Texas Jurisdiction and
Venue. You hereby consent and agree that state courts located in Dallas County, Texas and the United States District Court for the Northern District of Texas (Dallas Division) each shall have personal jurisdiction and proper venue with respect
to any dispute between you and the Company arising in connection with the Restricted Stock Units, the Plan, or this Agreement. In any such dispute, each of you and the Company agree not to raise, and do hereby expressly waive, any objection or
defense to such jurisdiction as an inconvenient forum. 
 28. Amendment. This Agreement may be amended in accordance with
the terms of the Plan. 
 29. The Plan. This Agreement is subject to all the terms, conditions, limitations and
restrictions contained in the Plan.

 Exhibit II 
 In addition to the benefits, perquisites and compensation set forth in the Agreement, Executive shall be entitled to receive the benefits, perquisites and compensation set forth in this Exhibit II,
subject to the terms and conditions set forth herein: 
 (a) Service Crediting. For purposes of eligibility to receive
retiree medical benefits under any retiree medical benefit plan or program of the Company or its Affiliates, Executive shall be deemed eligible for such benefits upon retirement at any time after reaching age 55, so long as Executive has completed
five (5) years of service with the Company and its Affiliates following January 31, 2008; provided that in all other respects Executive shall be subject to the terms and conditions of any such retiree medical plan (including with respect
to any requirement for employee contributions). 
 (b) Life Insurance. During the Employment Term, the Company shall
maintain in effect, at the Company’s cost, a ten (10) year term life insurance policy on the life of Executive in the amount of $10,000,000, payable to such beneficiary as designated by Executive. If Executive terminates employment prior
to the expiration of the ten (10) year term of such policy, he may continue to maintain the policy at his own expense or the policy may be allowed to lapse. 
 (c) Annuity Benefit. Provided Executive remains continuously employed by the Company through December 31, 2014, the Company shall purchase on Executive’s behalf, as soon as
administratively feasible, but in no event later than March 15, 2015, a single premium annuity contract from an insurance company acceptable to Executive, providing an annual annuity commencing on such date thereafter and payable in such form
(e.g., life annuity, term certain and life annuity or joint and survivor annuity) as specified by Executive (the “Annuity Contract”). The Annuity Contract shall provide the specified annuity in the amount which may be
provided by a single premium of the net amount remaining after withholding all applicable income and payroll taxes, from a non-periodic payment of $3,000,000. If, prior to December 31, 2014, Executive has been terminated without Cause by the
Company, resigns for Good Reason, or terminates employment due to death or Disability, Executive (or his personal representative, as the case may be) shall be entitled to such Annuity Contract as soon as administratively practicable following
Executive’s termination of employment, but in no event later than March 15th of the year following such termination of employment. If Executive is terminated by the Company for Cause or resigns without Good Reason prior to
December 31, 2014, he shall forfeit his right to the Annuity Contract. 
 (d) Additional Cooperation.
Notwithstanding anything in Section 9(n) to the contrary, (i) Executive and the Company shall coordinate with Executive’s schedule so as to minimize the extent to which any cooperation obligation under Section 9(n) interferes
with Executive’s other business activities, and (ii) the Company shall pay Executive’s travel expenses (transportation, lodging, meals, etc.) in a level of comfort comparable to that enjoyed while employed hereunder and reasonable
attorneys’ fees of counsel selected by him, incurred in order to satisfy Executive’s obligations under Section 9(n).
