 Execution Copy 
 EMPLOYMENT AGREEMENT 
 This EMPLOYMENT AGREEMENT (the “Agreement”) dated July 1, 2008 is made by and between ENERGY FUTURE HOLDINGS CORP. (the
“Company”) and PAUL KEGLEVIC (the “Executive”). 
 WITNESSETH 
 WHEREAS, the Company desires to employ Executive and Executive desires to accept such employment commencing on the Effective Date (as defined herein);
and 
 WHEREAS, the parties wish to enter into this Agreement establishing certain terms and conditions related to Executive’s
employment. 
 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 8 of this Agreement, this Agreement and
Executive’s employment hereunder shall be effective as of July 1, 2008 (“Effective Date”) and shall continue until the third anniversary of the Effective Date (the “Initial Term”). Subject to the provisions of
Section 8 of this Agreement, the Initial Term shall be extended as follows: (i) this Agreement shall automatically renew for an additional one (1) year period commencing immediately following the last day of the Initial Term and each
one (1) year period thereafter (each, a “Renewal Term”), unless, the Company or Executive provides the other party written notice of non-renewal at least sixty (60) days prior to the end of the applicable term. The period during
which Executive is employed by the Company hereunder is hereinafter referred to as the “Employment Term”. 
 2. Positions.

 a. During the Employment Term, Executive shall serve as Executive Vice President and Chief Financial Officer of the Company. In such
position, Executive shall have such duties, authority and responsibilities as shall be determined from time to time by the board of directors of the Company (the “Board”), which duties, authority and responsibilities shall be customary for
Executive’s position in a business of a similar size, type and nature to that of the Company. Executive shall report to the Chief Executive Officer and President of the Company with respect to his responsibilities to the Company. 
 b. During the Employment Term, Executive will devote Executive’s full business time and best efforts to the performance of his duties hereunder and
will not engage in any other business, profession or occupation for compensation or otherwise which would conflict or interfere with the rendition of such services either directly or indirectly, without the prior written consent of the Board;
provided, however, that nothing herein shall preclude Executive from serving on the outside board of directors of one other company and, subject to the prior approval of the Board, which approval shall not be unreasonably withheld,
from accepting appointment to or continuing to serve on such additional boards of directors or trustees of any other business, corporation or charitable organization; provided, further, that, in each case, such activities do not
conflict or interfere with the performance of Executive’s duties hereunder or conflict with Section 9. 







 3. Base Salary and Sign On Bonus. During the Employment Term, the Company shall pay Executive a
base salary at the annual rate of $600,000, payable in regular installments in accordance with the Company’s usual payment practices. Executive shall be entitled to such increases, if any, in his base salary as may be determined from time to
time in the sole discretion of the Board, in accordance with the Company’s normal annual review process for executives. Executive’s annual base salary, as in effect from time to time, is hereinafter referred to as the “Base
Salary”. Additionally, Executive shall be entitled to $550,000 in sign on bonuses, less applicable withholdings and deductions, payable as follows: (a) $250,000 payable on or before Executive’s second pay period of employment;
(b) $150,000 payable on the first pay period following Executive’s first anniversary of employment; and (c) $50,000 payable on the first pay period following Executive’s second, third, and fourth anniversaries of employment.

 4. Annual Bonus. With respect to each full fiscal year during the Employment Term, Executive shall have the opportunity to earn an
annual bonus award (the “Annual Bonus”) of 75% of his Base Salary (“Annual Bonus Target”), as in effect at the beginning of the applicable fiscal year, based upon the achievement of annual performance targets established by the
Board; provided, however, if Executive achieves superior performance targets as established by the Board, then Executive shall be eligible to receive a bonus award constituting 200% of his Annual Bonus Target. The Annual Bonus, if any,
shall be paid to Executive within two and one half (2.5) months after the end of the applicable fiscal year. 
 5. Stock
Compensation; Employee Benefits; Perquisites; Fringe Benefits. 
 a. Upon, or as soon as practicable after the Effective Date, the Company
shall grant Executive: (i) an option to purchase 2,500,000 shares of Company common stock (“Common Stock”) on terms and conditions set forth in the Nonqualified Stock Option Agreement in substantially the form attached as Exhibit I
(such award, the “Option Award”). The Option Award shall be subject to the further terms and conditions of the Management Stockholder’s Agreement and the Sale Participation Agreement each in substantially the form attached as Exhibit
III and IV, respectively; and (ii) deferred share units (“Deferred Share Units”) representing the right to receive 225,000 shares of Stock on terms and conditions set forth in the Deferred Share Agreement in substantially the form
attached as Exhibit II. In addition, upon or as soon as practicable after the Effective Date, Executive shall have the option to purchase an aggregate number of shares of Stock with a fair market value of up to $1,000,000. These awards shall be
subject to the further terms and conditions of the Management Stockholder’s Agreement and the Sale Participation Agreement each in substantially the form attached as Exhibit III and IV, respectively. 
 b. During the Employment Term, Executive shall be entitled to participate in the Company’s group health, life, disability and other active employee
and retiree welfare benefit plans and arrangements, and tax qualified and nonqualified savings and pension benefit plans, as in effect from time to time (collectively “Employee Benefits”), on a basis which is no less favorable than is
provided to other similarly situated executives of the Company, to the extent consistent with applicable law and the terms of the applicable plans and standard perquisites. 
  

 2 








 c. During the Employment Term, Executive shall be entitled to fringe benefits consistent with the
practices of the Company. Fringe benefits shall be provided to Executive to the extent the Company provides similar benefits to other similarly situated Company executives. 
 6. Business Expenses. Subject to the Company’s standard policies and procedures with respect to expense reimbursement as applied to its
executive employees generally, the Company shall reimburse Executive for, or pay on behalf of Executive, reasonable and appropriate expenses incurred by Executive for business related purposes. 
 7. Relocation Expenses. The Company shall reimburse Executive for all reasonable relocation expenses directly related to Executive’s
relocation from the metropolitan Chicago, Illinois, area to the metropolitan Dallas, Texas area in accordance with terms of the Company’s relocation policy and as otherwise provided in Appendix A hereto. To the extent the Company’s payment
or reimbursement of such expenses are required to be included in the Executive’s income for income tax purposes or as wages for employment tax purposes, the Company shall pay to the Executive an amount necessary to “gross up”
Executive for state and federal income and employment tax purposes (and for such taxes on such gross-up payment), which gross up amount shall be paid to Executive no later than the end of the applicable calendar year in which the expenses were
incurred. 
 8. Termination. The Employment Term and 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 any termination of Executive’s employment.
Notwithstanding any other provision of this Agreement, the provisions of this Section 8 shall exclusively govern Executive’s rights upon termination of employment with the Company and its Affiliates (as defined in Section 9(c) below).

 a. By the Company For Cause or By Executive Due to Voluntary Resignation Without Good Reason. 
 (i) The Employment Term and Executive’s employment hereunder may be terminated by the Company for Cause (as defined below) or by Executive’s
voluntary resignation without Good Reason (as defined below). If Executive’s employment is terminated by the Company for Cause, or if Executive resigns without Good Reason, Executive shall be entitled to receive: 
 (A) within ten (10) business days following the date of termination, accrued, but unpaid Base Salary and unused vacation, earned through the date
of termination; 
 (B) accrued, but unpaid Annual Bonus, earned for any previously completed fiscal year, paid in accordance with
Section 4 (except to the extent payment is otherwise deferred pursuant to any applicable deferred compensation arrangement with the Company); 
  

 3 








 (C) reimbursement, within sixty (60) days following submission by Executive to the Company, as
applicable, of appropriate supporting documentation, for any unreimbursed business expenses properly incurred by Executive in accordance with the Company’s policies prior to the date of Executive’s termination; provided claims for such
reimbursement (accompanied by appropriate supporting documentation) are submitted to the Company within ninety (90) days following the date of Executive’s termination of employment; 
 (D) such Employee Benefits and stock compensation, if any, as to which Executive may be entitled under the employee benefit plans of the Company or any
agreement between the Company and Executive; and 
 (E) any amounts payable or that may become payable pursuant to Section 8(e)(ii) and
Section 10(g) (the amounts described in clauses (A) through (E) hereof being referred to as the “Accrued Rights”). 
 Following such
termination of Executive’s employment by the Company for Cause or voluntary resignation by Executive without Good Reason, except as set forth in this Section 8(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 9), (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 (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 equally); (ii) a transfer of Executive’s primary workplace by more
than thirty-five (35) miles from the current workplace; (iii) a substantial adverse change in Executive’s duties or responsibilities; (iv) any material breach of this Agreement; or (v) an adverse change in Executive’s
line of reporting to superior officers pursuant to the terms of this Agreement; provided, however, that any isolated, insubstantial and inadvertent failure by the Company that is not in bad faith and is cured within ten
(10) business days after Executive gives the Company written notice of any such event set forth above, shall not constitute Good Reason. 
 b. Disability or Death. 
 (i) The Employment Term and Executive’s employment hereunder shall terminate upon
Executive’s death and may be terminated by the Company if Executive has 

  

 4 








 
a Disability as hereinafter defined. Upon termination of Executive’s employment hereunder for either Disability or death, Executive or Executive’s
estate (as the case may be) shall be entitled to receive: 
 (A) the Accrued Rights; and 
 (B) a pro-rata portion of the Annual Bonus Target, if any, that Executive would have been entitled to receive pursuant to Section 4 hereof for the
fiscal year of termination, multiplied by a fraction, the numerator of which is the number of days during which Executive was employed by the Company in the fiscal year of Executive’s termination, and the denominator of which is 365 (the
“Pro-Rata Bonus”), with such Pro-Rata Bonus payable to Executive pursuant to Section 4 as if Executive’s employment had not terminated. 
 Following Executive’s termination of employment due to death or Disability, except as set forth in this Section 8(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 mental or physical impairment for a period of time which is covered by the Company’s
short term disability plan, Executive’s employment shall not be deemed terminated by the Company and Executive shall not be able to resign with Good Reason. Any question as to the existence of the Disability of Executive as to which Executive
and the Company cannot agree shall be determined in writing by a qualified independent physician mutually acceptable to Executive and the Company. If Executive and the Company cannot agree as to a qualified independent physician, each shall appoint
a physician and those two physicians shall select a third who shall make such determination in writing. The determination of Disability made in writing to the Company and Executive shall be final and conclusive for all purposes of the Agreement and
any other agreement with Executive that incorporates this definition of “Disability”. 
 c. By the Company Without Cause;
Resignation by Executive for Good Reason. The Employment Term and Executive’s employment hereunder may be terminated by the Company without Cause (other than by reason of death or Disability) or upon Executive’s resignation for Good
Reason. If Executive’s employment is terminated by the Company without Cause (other than by reason of death or Disability) or Executive resigns for Good Reason (except as otherwise provided in Section 8(e)), Executive shall be entitled to
receive: 
 (i) the Accrued Rights; 
 (ii) provided Executive (x) does not violate the restrictions set forth in Section 9 of this Agreement and (y) executes, delivers and does not revoke a general release of claims against the Company, its subsidiaries and its
stockholders (excluding claims for indemnification, claims for coverage under officer and director policies, and claims as a stockholder of the Company): 
 (A) for a termination occurring on or prior to the second anniversary of the Effective Date, a lump sum payment equal to two (2) times the sum of: (1) Executive’s annualized Base Salary and
(2) Executive’s Annual Bonus Target, 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;
or 
  

 5 








 (B) for a termination occurring after the second anniversary of the Effective Date, a lump sum payment
of an amount equal to: (1) two (2) times Executive’s Base Salary, (2) the Pro-Rata Bonus, and (3) the matching contributions which would have been made on behalf of Executive pursuant to the Company’s Salary Deferral
Program had Executive continued his participation in such plan as in effect on the date of such termination for an additional twelve (12) months, payable as soon as practicable but no later than the earlier of: (i) March 15 following
the calendar year in which termination occurs or (ii) ninety (90) days following termination. 
 (C) Executive, his spouse and
eligible dependents (to the extent covered immediately prior to such termination) shall continue to be eligible to participate in all of the Company’s group health plans on the same terms and conditions as active employees of the Company until
the earlier of (x) two (2) years from the date of termination of Executive’s employment (the “Severance Period”), to the extent that Executive was eligible to participate in such plans immediately prior to the date of
termination, or (y) until Executive is, or becomes, eligible for comparable coverage under the group health plans of a subsequent employer, provided that, if Executive continues to receive benefits pursuant to this Section 8(c)(ii)(C)
during a period of time during which, in the absence of the benefits provided in this Section 8(c)(ii)(C), Executive would not otherwise be entitled to continuation coverage under Section 4980B of the Internal Revenue Code of 1986, as
amended (the “Code”), Executive shall receive reimbursement for all medical expenses on the date no later than the end of the calendar year immediately following the calendar year in which the applicable expenses have been incurred. The
COBRA health care continuation coverage period under Section 4980B of the Code, or any replacement or successor provision of United States tax law, shall run concurrently with the Severance Period. 
 Following Executive’s termination of employment by the Company without Cause (other than by reason of Executive’s death or Disability) or upon Executive’s
resignation for Good Reason, except as set forth in this Section 8(c) or otherwise provided in Section 8(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, unless Executive’s employment is
earlier terminated pursuant to paragraphs (a), (b), (c), or (e) of this Section 8, the Employment Term shall expire and 

  

 6 








 
Executive’s employment hereunder shall terminate on the close of business on the day immediately preceding the commencement of a subsequent Renewal
Term, and Executive shall be entitled to receive the Accrued Rights and the rights set forth in Section 8(d)(ii) below. 
 (ii) In the
event the Company elects not to extend the Employment Term pursuant to Section 1, unless Executive’s employment is earlier terminated pursuant to paragraphs (a), (b), (c), or (e) of this Section 8, the Employment Term shall
expire and Executive’s employment hereunder shall terminate on the close of business on the day immediately preceding the commencement of a subsequent Renewal Term, and Executive shall be entitled to receive the payments and benefits applicable
to a termination of Executive’s employment without Cause pursuant to Section 8(c) or Section 8(e), as applicable. Except as set forth in this Section 8(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 9 of this Agreement and
(y) executes, delivers and does not revoke a general release of claims against the Company, its subsidiaries and its stockholders (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 two times the sum of: (1) Executive’s annualized Base Salary and (2) Executive’s Annual Bonus Target 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; and 
 (iii) provided Executive (x) does not violate the restrictions set forth in Section 9 of this Agreement and (y) executes, delivers and does not revoke a general release of claims against the Company, its subsidiaries and its
stockholders (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 (x) termination of the Severance Period, to the
extent that Executive was eligible to participate in such plans immediately prior to the date of termination, or (y) until Executive is, or becomes, eligible for comparable coverage under the group health plans of a subsequent employer,
provided that, if Executive continues to receive benefits pursuant to this Section 8(e)(i)(C) during a period of time during which, in the absence of the 

  

 7 








 
benefits provided in this Section 8(e)(i)(C) Executive would not otherwise be entitled to continuation coverage under Section 4980B of the Code,
Executive shall receive reimbursement for all medical expenses on the date no later than the end of the calendar year immediately following the calendar year in which the applicable expenses have been incurred. The COBRA health care continuation
coverage period under Section 4980B of the Code, or any replacement or successor provision of United States tax law, shall run concurrently with the Severance Period. 
 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 8(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. 
 f. Notice of Termination. Any purported termination
of employment by the Company or by Executive (other than due to Executive’s death) shall be communicated by written Notice of Termination to the other party hereto in accordance with Section 10(j) hereof. For purposes of this Agreement, a
“Notice of Termination” shall mean a notice which shall indicate the specific termination provision in this Agreement relied upon and shall set forth in reasonable detail the facts and circumstances claimed to provide a basis for
termination of employment under the provision so indicated. 
 g. Section 4999. If, by reason of, or in connection with, any
transaction that occurs after the Effective Date, Executive would be subject to the imposition of the excise tax imposed by Section 4999 of the Code related to Executive’s employment with or Company or Holdings, whether before or after
termination of Executive’s employment, but the imposition of such tax could be avoided by approval of shareholders described in Section 280G(b)(5)(B) of the Code, then Executive may cause the Company or Holdings to seek such approval, in
which case the Company and Holdings will use their reasonable best efforts to cause such approval to be obtained and Executive will cooperate and execute such waivers as may be necessary so that such approval avoids imposition of any excise tax
under Section 4999. If Executive fails to cause the Company or Holdings to seek such approval, or if Executive does cause the Company or Holdings to seek such approval, but fails to cooperate and execute such waivers as may be necessary in the
approval process, Exhibit V shall not apply and Executive shall not be entitled to any gross-up payment for any resulting tax under Section 4999. If such approval, even if sought and obtained, would not avoid imposition of the excise tax
imposed under Section 4999, then the provisions of Exhibit V attached hereto shall apply without any precedent obligation of Executive to seek such approval. 
 9. 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, 6
th Floor 
 Dallas, Texas 75201

 (214) 812-6032 (facsimile); 
 (ii) at any time during the Employment Term and for a period of eighteen (18) months thereafter (the “Non-Compete Period”), directly or indirectly, act as a proprietor, investor, director, officer, employee, substantial
stockholder, consultant, or partner in any Competing Business in Texas or any other geographic area in which 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 eighteen (18) months thereafter, directly or indirectly
(A) solicit customers or clients of the Company or any of its Affiliates to terminate their relationship with the Company or any of its Affiliates or otherwise solicit such customers or clients to compete with any business of the Company or any
of its Affiliates, or (B) solicit or offer employment to any person who is, or has been at any time during the twelve (12) months immediately preceding the termination of Executive’s employment, employed by the Company or any of its
Affiliates; 
 provided that in each of (ii) and (iii) above, such restrictions shall not apply with respect to any member of the Sponsor Group or
any of its Affiliates that is not engaged in any business that competes, directly or indirectly, with the Company or any of its subsidiaries in any geographic area where they operate. Notwithstanding the foregoing, for the purposes of
Section 9(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 which are publicly traded on a national or regional stock exchange or
quotation system or on the over-the-counter market if Executive (I) is not a controlling person of, or a member of a group which controls, such person and (II) does not, directly or indirectly, own 5% or more of any class of securities of such
Person, and (B) the Non-Compete Period shall not be triggered by any exercise of tag-along rights under the Sale Participation Agreement entered into between Executive and Texas Energy Future Holdings Limited Partnership (the “Sale
Participation Agreement”) or Drag Transaction (as defined in the Sale Participation Agreement) that may occur after the date hereof. 
 b. Notwithstanding clause (a) above, if at any time a court holds that the restrictions stated in such clause (a) are unreasonable or otherwise unenforceable under circumstances then existing, the parties hereto agree that the
maximum period, scope or geographic area determined to be reasonable under such circumstances by such court will be 

  

 9 








 
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 Section 9(a), 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 between Executive and the Company (the “MSA”), shall be limited to those set forth in Section 22(c) of the MSA. 
 c. For purposes of this Agreement, the terms listed below shall be defined as follows: 
 (i) Affiliate shall mean with respect to any Person, any entity directly or indirectly controlling, controlled by or under common control with
such Person; provided, however, for purposes of this Agreement, Texas Energy Future Co-Invest, LP shall not be deemed to be an Affiliate of the Sponsor Group or any member of the Sponsor Group. 
 (ii) Competing Business shall mean any business that directly or indirectly competes, at the relevant determination date, with one or more of the
businesses of the Company or any of its Affiliates in any geographic area where Texas Energy Future Holdings Limited Partnership, the Company, or any of their respective subsidiaries operates. 
 (iii) Confidential Information shall mean information: (i) disclosed to or known by Executive as a consequence of or through his employment
with the Company or any Affiliate; (ii) not publicly available or not generally known outside the Company or any Affiliate; and (iii) that relates to the business and development of the Company or any Affiliate. Any information that does
not meet each of the criteria listed above (in subsections (i) – (iii)) shall not constitute Confidential Information. By way of example, Confidential Information shall include but not be limited to the following: all non-public
information or trade secrets of the Company or any Affiliate that gives the Company or any Affiliate a competitive business advantage or the opportunity of obtaining such advantage, or disclosure of which might be 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), operational information, plans, and
strategies; business and marketing strategies and plans for various products and services; rate and regulatory strategy and plans; information regarding suppliers, consultants, employees, and contractors; technical information concerning products,
equipment, services, and processes; procurement procedures; pricing and pricing techniques; information concerning past, current and prospective customers, investors, and business affiliates; plans or strategies for expansion or acquisitions;
budgets; research; trading methodologies and terms; communications information; evaluations, opinions, and interpretations of information and data; marketing and merchandising techniques; electronic databases; models; specifications; computer
programs; contracts; bids or proposals; technologies and methods; training methods and processes; organizational structure; 

  

 10 








 
personnel information; payments or rates paid to consultants or other service providers; and the Company’s or any Affiliate’s files, physical or
electronic documents, equipment, and proprietary data or material in whatever form including all copies of all such materials. By way of clarification (but not limitation), information that Executive conceived or developed during his employment with
the Company or learned from other employees or contractors of the Company 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 Group shall mean, collectively the Company, its subsidiaries, the members of the Sponsor Group and their respective Affiliates.

 (vi) Sponsor Group shall mean Kohlberg Kravis Roberts & Co. L.P., TPG Capital L.P., and Goldman, Sachs & Co.

 10. 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 of the Company’s obligations 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. 
  

 11 








 f. Set Off; Mitigation. The Company’s obligation to pay Executive the amounts provided and to
make the arrangements provided hereunder shall not be subject to setoff, counterclaim or recoupment of amounts owed by Executive to the Company or its Affiliates. Executive shall not be required to mitigate the amount of any payment provided for
pursuant to this Agreement by seeking other employment 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 Section 409A of the Code. Notwithstanding anything herein to the contrary, if, at the time of Executive’s termination
of employment with the Company, the Company has securities which are publicly traded on an established securities market, and Executive is a “specified employee” (as defined in Section 409A of the Code), and the deferral of the
commencement of any payments or benefits otherwise payable pursuant to Section 8 as a result of such termination of employment is necessary in order to prevent any accelerated or additional tax under Section 409A of the Code, then, to the
extent permitted by Section 409A of the Code, the Company will defer the commencement of the payment of any such payments or benefits hereunder (without any reduction in such payments or benefits ultimately paid or provided to Executive) until

 Section 2.4 – Adjustments to
Option 
 The Option shall be subject to the adjustment provisions of Sections 8 and 9 of the Plan, provided, however, that in
the event of the payment of an extraordinary dividend by the Company to its stockholders, then: the Exercise Price of the Option shall be reduced by the amount of the dividend paid, but only to the extent the Committee determines it to be permitted
under applicable tax laws and not have adverse tax consequences to the Optionee under Section 409A of the Code; and, if such reduction cannot be fully effected due to such tax laws without adverse tax consequences to the Optionee, then the

 5 








 
amount of the dividend not permitted to be applied to reduce the Exercise Price of the applicable Option as follows: (a) for each Share subject to a
vested Option, immediately upon the date of such dividend payment; and (b), for each Share subject to an unvested Option, on the date on which such Option becomes vested and exercisable with respect to such Share. 
 ARTICLE III 
 PERIOD OF EXERCISABILITY 

 Section 3.1 – Commencement of Exercisability 
 (a) So long as the Optionee continues to be employed by the Company or any other Service Recipients, the Option shall become exercisable pursuant to the following schedules: 
 (i) Time Option. The Time Option shall become vested and exercisable with respect to 20% of the Shares subject to such Option on each of the first
five anniversaries of the Closing Date. 
 (ii) Performance Option. The Performance Option shall be eligible to become vested and
exercisable as to 20% of the Shares subject to such Option at the end of each of the five Fiscal Years if the Company, on a consolidated basis, achieves its annual EBITDA targets as set forth in Schedule A attached hereto (each an
“EBITDA Target”) for the given Fiscal Year. Notwithstanding the foregoing, in the event that an EBITDA Target is not achieved in a particular Fiscal Year, then that portion of the Performance Option that was eligible to vest but
failed to vest due to the Company’s failure to achieve its EBITDA Target shall nevertheless vest and become exercisable at the end of either of the two immediately subsequent Fiscal Years if the applicable two- or three-year cumulative
EBITDA Target (each a “Cumulative EBITDA Target”) set forth on Schedule A attached hereto is achieved on a cumulative basis at the end of either of the two immediately subsequent Fiscal Years with respect to a Fiscal Year
completed no more than two years prior to the then completed Fiscal Years; provided that, in the event that an EBITDA Target is not achieved in either of Fiscal Years 2011 or 2012, then that portion of the Performance Option that was eligible to
vest but failed to vest due to the Company’s failure to achieve its EBITDA Target or the applicable Cumulative EBITDA Target shall nevertheless vest and become exercisable at the end of either of the two immediately subsequent fiscal years of
the Company if the budgeted EBITDA target set by the Board and the Committee in respect of such Fiscal Year of the Company is achieved and the excess over such budgeted amount is sufficient to satisfy the shortfall from Fiscal Year 2011 or
2012. 
 (b) Notwithstanding any of Section 3.1(a) above, upon the occurrence of a termination of employment without Cause, termination
of employment on account of the Company or other applicable Service Recipient’s failure to renew the Optionee’s existing employment agreement, or a resignation by the Optionee for Good Reason following the occurrence of a Change in
Control, the Time Option shall become immediately exercisable as to 100% of the shares of Common Stock subject to such Option immediately prior to the Change of Control; and 
 (c) Notwithstanding any of Section 3.1(a) above, upon the occurrence of a Liquidity Event, subject to the Optionee’s employment on the date of
the event, the Performance Option shall become immediately exercisable as to 100% of the shares of Common Stock subject to such Option immediately prior to the Liquidity Event (but only to the extent such Option has not otherwise terminated or
become exercisable). If immediate exercisability as to 100% of the shares of Common Stock subject to the Option pursuant to the preceding sentence would cause the Sponsor IRR and Sponsor Return not to be achieved, “100%” in the preceding
sentence shall be replaced with the maximum percentage so that either the Sponsor IRR or Sponsor Return is achieved. 
  

 6 








 (d) In the event that the Sponsor Group receives Marketable Securities in an event constituting a
Measurement Date (including, following a public offering, shares of Common Stock) in excess of more than 25% of the aggregate amount realized in such event, (1) Sponsor IRR and Sponsor Return shall be initially calculated at the time of the
Measurement Date without regard to the value of such Marketable Securities so received and such resulting Sponsor Return and Sponsor IRR shall be used to determine vesting of Shares of Common Stock subject to Performance Options in accordance with
Section 3.1(c) above; and (2) if the Sponsor Return and/or Sponsor IRR as calculated in (1) above do not result in 100% vesting of the outstanding exercisable Shares of Common Stock subject to such Option immediately prior to the
Measurement Date, Sponsor Return and Sponsor IRR shall be recalculated upon each direct or indirect disposition of such Marketable Securities by the Sponsor Group for cash, discounting the cash received to determine its present value at the time of
the Measurement Date. If such recalculated Sponsor IRR and/or Sponsor Return would have resulted in 100% vesting of all Shares of Common Stock subject to Performance Options at the time of the Measurement Date, then all such Options shall
immediately vest; provided, however, that any Optionee whose employment is terminated without Cause by the Company or as a result of the Company or other applicable Service Recipient’s failure to renew his employment agreement, or
who terminates his employment with Good Reason, such Optionee’s Performance Options having been forfeited or cancelled between the occurrence of the Measurement Date and the subsequent vesting of such Performance Options, in accordance with
this Section 3.1(d), shall be entitled to the difference between the price per Share paid on the Measurement Date and the strike price of the Performance Options that were so cancelled or forfeited. 
 (e) Notwithstanding the foregoing, no Option shall become exercisable as to any additional shares of Common Stock following the termination of employment
of the Optionee for any reason and any Option, which is unexercisable as of the Optionee’s termination of employment, shall immediately expire without payment therefor. 
 Section 3.2 – Expiration of Option 
 Except as otherwise provided in Section 5 or 6 of the
Management Stockholder’s Agreement, the Optionee may not exercise the Option to any extent after the first to occur of the following events: 
 (a) The tenth anniversary of the Grant Date so long as the Optionee remains employed with the Company or any Service Recipient through such date; 
 (b) The first anniversary of the date of the Optionee’s termination of employment with the Company and all Service Recipients, if the Optionee’s employment is terminated by reason of death or Disability;

 (c) Immediately upon the date of an Optionee’s termination of employment by the Company and all Service Recipients for Cause;

 (d) Thirty (30) days after the date of an Optionee’s resignation from employment with the Company and all Service Recipients
without Good Reason (except due to death or Disability); 
 (e) One hundred and eighty (180) days after the date of: (i) an
Optionee’s resignation from employment with the Company and all Service Recipients for Good Reason; (ii) an Optionee’s Retirement; or (iii) an Optionee’s termination of employment by the Company and all Service Recipients


  

 7 








 
without Cause (for any reason other than as set forth in Sections 3.2(b) or 3.2(g)), including upon nonrenewal of Optionee’s existing employment
agreement by the Company or other applicable Service Recipient, in the event such termination listed in (i), (ii), or (iii) occurs prior to the fifth anniversary of the Closing Date; 
 (f) The Extended Exercise Date in the event of (i) an Optionee’s resignation from employment with the Company and all Service Recipients for
Good Reason; (ii) an Optionee’s Retirement; or (iii) an Optionee’s termination of employment by the Company and all Service Recipients without Cause (for any reason other than as set forth in Sections 3.2(b) or 3.2(g)), including
upon nonrenewal of Optionee’s existing employment agreement by the Company or other applicable Service Recipient, and any such termination listed in (i), (ii), or (iii) occurs on or after the fifth anniversary of the Closing Date;

 (h) Immediately upon the date of an Optionee’s breach of the provisions Section 22(a)(ii) of the Management Stockholder’s Agreement; or

 (i) At the discretion of the Company, if the Committee so determines pursuant to Section 9 of the Plan. 
 Notwithstanding the foregoing, the time periods set forth in this Section 3.2 shall not begin to run with respect to Performance Options that vest
in accordance with Section 3.1(a)(ii) above until the time at which the Board certifies the financial statements for the Company for the Fiscal Year immediately preceding the Fiscal Year in which, or for the Fiscal Year in which, termination of
employment occurs. 
 ARTICLE IV 
 EXERCISE OF OPTION 
 Section 4.1. – Person Eligible to Exercise 
 During the lifetime of the Optionee, only the Optionee (or his duly authorized legal representative) may exercise an Option or any portion thereof. After
the death of the Optionee, any exercisable portion of an Option may, prior to the time when an Option becomes unexercisable under Section 3.2, be exercised by his personal representative or by any person empowered to do so under the
Optionee’s will or under the then applicable laws of descent and distribution. 
 Section 4.2 – Partial Exercise 
 Any exercisable portion of an Option or the entire Option, if then wholly exercisable, may be exercised in whole or in part at any time prior to the time
when the Option or portion thereof becomes unexercisable under Section 3.2; provided, however, that any partial exercise shall be for whole shares of Common Stock only. 
 Section 4.3 – Manner of Exercise 
 An Option, or
any exercisable portion thereof, may be exercised solely by delivering to the Secretary or his office all of the following prior to the time when the Option or such portion becomes unexercisable under Section 3.2: 
 (a) Notice in writing signed by the Optionee or the other person then entitled to exercise the Option or portion thereof, stating that the Option or
portion thereof is thereby exercised, such notice complying with all applicable rules established by the Committee; 
  

 8 








 (b) (i) Full payment (in cash, by check, or by a combination thereof or through tender of previously
owned Shares (any such Shares valued at Fair Market Value on the date of exercise) that the Participant has held for at least six months (or such other period as may be required by the Company’s accountants but only to the extent required to
avoid liability accounting under FAS 123(R) or any successor standard thereto)) for the shares with respect to which such Option or portion thereof is exercised or (ii) indication that the Optionee elects to have the number of Shares that would
otherwise be issued to the Optionee reduced by a number of Shares having an equivalent Fair Market Value to the payment that would otherwise be made by the Optionee to the Company pursuant to clause (i) of this subsection (b); 
 (c)(i) Full payment (in cash or by check or by a combination thereof) to satisfy the minimum withholding tax obligation with respect to which such Option
or portion thereof is exercised; (ii) notice in writing that the Optionee elects to have the number of Shares that would otherwise be issued to the Optionee reduced by a number of Shares having an equivalent Fair Market Value to the payment
that would otherwise be made by the Optionee to the Company pursuant to clause (i) of this subsection (c); 
 (d) A bona fide written
representation and agreement, in a form satisfactory to the Committee, signed by the Optionee or other person then entitled to exercise such Option or portion thereof, stating that the shares of Common Stock are being acquired for his own account,

thereunder, and that the Optionee or other person then entitled to exercise such Option or portion thereof will indemnify the Company against and hold it free and harmless from any loss, damage, expense or liability resulting to the Company if any
sale or distribution of the shares by such person is contrary to the representation and agreement referred to above; provided, however, that the Committee may, in its reasonable discretion, take whatever additional actions it deems
reasonably necessary to ensure the observance and performance of such representation and agreement and to effect compliance with the Act and any other federal or state securities laws or regulations; and

appropriate proof of the right of such person or persons to exercise the Option. 
 Without limiting the generality of the foregoing, the Committee may
require an opinion of counsel acceptable to it to the effect that any subsequent transfer of shares acquired on exercise of an Option does not violate the Act, and may issue stop-transfer orders covering such shares. Share certificates evidencing
stock issued on exercise of this Option shall bear an appropriate legend referring to the provisions of subsection (d) above and the agreements herein. The written representation and agreement referred to in subsection (d) above shall,
however, not be required if the shares to be issued pursuant to such exercise have been registered under the Act, and such registration is then effective in respect of such shares.

the exercise of an Option, or any portion thereof, 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. The Company shall not

 Except as otherwise provided in Section 2.4 of this Agreement, the holder of an Option shall not be, nor have any of the rights or privileges of, a
stockholder of the Company in respect of any shares purchasable upon the exercise of the Option or any portion thereof unless and until certificates representing such shares shall have been issued by the Company to such holder or the Shares have
otherwise been recorded in the records of the Company as owned by such holder.

 Exhibit II 
 Deferred Share Agreement 
 This Deferred Share Agreement, dated as of July 1, 2008 (this
“Agreement”) by and among Energy Future Holdings Corp. (“EFH Corp.”) and Paul Keglevic (the “Executive”). 
 WHEREAS, the Executive is employed by EFH Corp., pursuant to an employment agreement dated July 1, 2008 (the “Employment Agreement”); 
 WHEREAS, in connection with Executive’s continued employment with EFH Corp., EFH Corp. has agreed to deliver 225,000 shares of common stock, no par
value, of EFH Corp. (“Shares”) under the terms of this Agreement; 
 NOW, THEREFORE, in consideration of the foregoing and
the respective representations, warranties, covenants and agreements set forth in this Agreement, and intending to be legally bound hereby, the parties hereto agree as follows: 
 ARTICLE I 
 DEFERRED SHARE AWARD 
 1.1 Number of Shares. Subject to the vesting requirements under Section 1.2(a), EFH Corp. shall deliver 225,000 Shares to the Executive on
the Distribution Date; provided, however, that if, after the date hereof and prior to the Distribution Date, there is a merger, spin-off, stock dividend, recapitalization, reorganization, stock split or other similar event that results in an
adjustment to an outstanding Share, the number of Shares to be delivered on the Distribution Date pursuant to this Section 1.1 shall be adjusted by the Board of Directors of EFH Corp. (or a committee thereof) in a manner which is necessary to
reflect the effect of such event on the Shares, consistent with the treatment of stockholders of EFH Corp. 
 1.2 Distribution Date.

 (a) Provided the Executive is employed on the third anniversary of the Effective Date (as defined by the Employment Agreement) of
Executive’s Employment Agreement with EFH Corp., the Shares shall vest and become nonforfeitable as to (i) 112,500 of the Shares on the date that is the third anniversary date of this Agreement and (ii) provided Executive is employed
on the fifth anniversary of the Effective Date of Executive’s Employment, the remaining 112,500 of the Shares shall vest and become nonforfeitable on the date that is the fifth anniversary date of this Agreement; provided that any
shares not yet vested shall become 100% vested and become nonforfeitable upon the first to occur of (x) immediately prior to a Change of Control (as defined in the 2007 Stock Incentive Plan for Key Employees of EFH Corp.) or (y) a
termination of Executive’s employment by EFH Corp. without Cause, by Executive for Good Reason or due to Executive’s death or Disability (“Cause,” “Good Reason” and “Disability” are defined as provided in the
Employment Agreement). The Shares shall be delivered to the Executive on the “Distribution Date”, which, subject to Section 3.3 below, shall be the earliest of the following dates: 
 (1) the occurrence of Executive’s separation of service for any reason, or, if necessary to meet the distribution requirement of Section 409A
of the Internal Revenue Code of 1986, as amended (the “Code”), the date that is six months and one day following such separation; and 
  

 16 








 (2) the occurrence of a change in the ownership or effective control of EFH Corp., or in the ownership
of a substantial portion of the assets of EFH Corp., occurring prior to Executive’s separation from service; and 
 (3) the 90th day following the fifth anniversary date of the Agreement. 
 in each case within the meaning of, and interpreted in a
manner consistent with regulations under, Section 409A of the Code. 
 (b) In the event of the Executive’s death, any distribution
to which the Executive would be entitled shall be made to the Executive’s estate or in accordance with the Executive’s will, the designated beneficiary. 
 1.3 Dividends. If there is any dividend or distribution in respect of outstanding Shares, the Executive shall be entitled to receive a payment in respect of the Shares in the amount and form, and at the time,
that such payment would have been made had the Executive actually held the underlying Shares, subject to applicable withholding taxes. 
 1.4
Right to Diversify. If, prior to the Distribution Date, any of the Shares, had they been delivered to the Executive, would be released from the transfer restrictions contained in the Management Stockholders Agreement and could have been sold
by the Executive without violation of applicable law or EFH Corp.’s trading policy, then upon and following the time of such release, the Executive shall have the right (a “Diversification Right”), exercisable by written notice
to EFH Corp. and subject to reasonable administrative limitations, to convert his right to receive any or all of the Shares on the Distribution Date into a right to receive cash on the Distribution Date. In addition, the Executive shall have a
Diversification Right with respect to any Shares that he would have been permitted to sell under the Sale Participation Agreement had he actually owned the Shares. In the event the Executive exercises a Diversification Right with respect to any
Shares, the cash to be delivered to him on the Distribution Date shall equal the Fair Market Value (as defined in the Management Stockholders Agreement) of the Shares as to which the Diversification Right was exercised on the date of such exercise,
as subsequently credited with investment returns based on notional investments as selected by the Executive from time to time following exercise of the Diversification Right from among those that EFH Corp. shall make available from among those
notional investments under any nonqualified deferred compensation plan then maintained by EFH Corp. (or, if no such notional investments are made available, with compound annual interest equal to the prevailing prime rate plus 2 percentage points,
but in no event shall it exceed EFH Corp.’s borrowing rate). 
  

 16 








 ARTICLE II 
 ADDITIONAL AGREEMENTS 
 2.1 Additional Agreements. Simultaneously with the execution of
this Agreement, the parties shall execute a Management Stockholders Agreement and a Sale Participation Agreement each of which shall apply to the Shares subject to this Agreement. 
 2.2 Special Put Right. If the Executive’s employment with EFH Corp. terminates for any reason prior to July 1, 2013, other than for
Cause or without Good Reason (as defined in the Employment Agreement), he shall have the right (but not the obligation) to sell to EFH Corp. all (but not less than all) of the Shares delivered pursuant to Section 1.2 for a purchase price of
$3,200,000 (the “Special Put Right”). In the event the Executive intends to exercise the Special Put Right, he shall send written notice, postmarked on or prior to the sixtieth day following termination of his employment, to EFH
Corp. of his intention to sell the Shares in exchange for the applicable purchase price (“Put Option Notice”). The completion of the purchase shall take place at the principal office of EFH Corp. no later than the twentieth business
day (such date to be determined by EFH Corp.) after the giving of the Put Option Notice. The applicable purchase price shall be paid by delivery to the Executive of a check payable to the order of the Executive against delivery of duly executed
stock powers transferring the Shares. 
 ARTICLE III 
 TAX MATTERS 
 3.1 Tax Withholding and Reporting. Upon any
Distribution Date, EFH Corp. shall be entitled to withhold from any payment or distribution to the Executive an amount necessary to satisfy applicable withholding taxes that become due by reason of such payment or distribution. EFH Corp.
acknowledges that for income tax purposes, the Executive will not include into income any amount payable on the Distribution Date until payment is actually made on the Distribution Date. EFH Corp. shall report and file all EFH Corp. tax returns and
information reports (including Form W-2) consistent with such position. 
 3.2 Delivery Before Liquidity. If, on the Distribution
Date, (i) Shares are to be delivered to the Executive, and (ii) the Executive cannot resell promptly within a reasonable time thereafter such Shares either because there is no public market for the Shares, or the Executive is restricted
under the Management Stockholders Agreement, EFH Corp. trading policies or applicable securities law from selling the Shares, EFH Corp. shall, immediately repurchase such number of Shares that, on the Distribution Date, have a Fair Market Value
equal to the minimum statutory tax withholding obligation attributable to delivery of the Shares. 
 3.3 Tax Assessment Prior to
Distribution Date. If there is a final tax assessment against the Executive that any amount otherwise payable under this Agreement is taxable in a year prior to the year that includes the Distribution Date, EFH Corp. shall immediately pay or
distribute the cash or Shares that otherwise would have been paid or delivered on the Distribution Date, and if the Executive cannot promptly within a reasonable time thereafter resell such Shares either because there is no public market for the
Shares, or the Executive is restricted under the Management Stockholders Agreement, EFH Corp. trading policies or applicable securities law from selling the Shares, EFH Corp. shall immediately repurchase such number of Shares that, on the
Distribution Date, have a Fair Market Value equal to the amount of such tax assessment (or, if such assessment exceeds the Fair Market Value of all of the Shares, then all of the Shares will be repurchased).

or 
 (ii)(A) counsel for the Management Stockholder (which counsel shall be reasonably acceptable to the Company) shall have
furnished the Company with an opinion or other advice, reasonably satisfactory in form and substance to the Company, that no such registration is required because of the availability of an exemption from registration under the Act and (B) if

 23

reasonably satisfactory in form and substance to the Company to the effect that such transfer will comply with the securities laws of such jurisdiction. 
 Notwithstanding the foregoing, the Company acknowledges and agrees that any of the following transfers of Stock are deemed to be in compliance with the Act and this Agreement (including without limitation any restrictions or prohibitions
herein), and no opinion of counsel is required in connection therewith: (1) a transfer made pursuant to Sections 3, 4, 5, 6 or 9 hereof, (2) a transfer (x) upon the death or Disability of the Management Stockholder to the Management

warranties and other obligations of this Agreement; and provided further that it is expressly understood and agreed that if such Management Stockholder’s Trust at any point includes any person or entity other than the Management
Stockholder, his spouse (or ex-spouse) or his lineal descendants (including adopted children) such that it fails to meet the definition thereof as set forth in Section 7(b) hereof, such transfer shall no longer be deemed in compliance with this
Agreement and shall be subject to 3(c) below and (4) a transfer made by the Management Stockholder, with the Board’s approval, to the Company or any Subsidiary of the Company.

ALL APPLICABLE FEDERAL AND STATE SECURITIES LAWS.” 
 (c) The Management Stockholder acknowledges that he has been advised that
(i) the Stock is characterized as “restricted securities” under the Act inasmuch as they are being acquired from the Company in a transaction not involving a Public Offering and that under the Act (including applicable regulations)
the Stock may be resold without registration 

  

 24

Rule 144 under the Act or otherwise, the Management Stockholder shall promptly notify the Company of such intended disposition and shall deliver to the Company at or prior to the time of such disposition such documentation as the Company may
reasonably request in connection with such sale and take any actions reasonably requested by the Coordination Committee prior to any such sale (provided that such instructions shall not have a disproportionate adverse impact on any Management
Stockholder vis-à-vis any other stockholders of the Company or limited partners of Parent) and, in the case of a disposition pursuant to Rule 144, shall deliver to the Company an executed copy of any notice on Form 144 required to
be filed with the SEC.

 4. Right of First Refusal. 
 (a) If, at any time after the fifth anniversary of the Closing Date and prior to the earlier to occur of a Change in Control or consummation of a
Qualified Public Offering, the Management Stockholder proposes to transfer any or all of the Management Stockholder’s Stock (any such transferee, the “ROFR Transferee”) (other than any transfer pursuant to clauses (1),
(2), (3) or (4) of Section 2(a)), the Management Stockholder shall notify the Company in writing of the Management Stockholder’s intention to transfer such Stock (such written notice, a “ROFR Notice”). The ROFR
Notice shall include a true and correct description of the number of shares of Stock to be transferred and the material terms of such proposed transfer (including the price and identity, including name and address, of the proposed transferee) and a
copy of any proposed documentation to be entered into with any ROFR Transferee in respect of such transfer) and shall contain an irrevocable offer to sell such Stock to the Company or its designees (as provided below) (in the manner set forth below)
at a purchase price equal to the minimum price at which the Management Stockholder proposes to transfer such Stock to any ROFR Transferee and on substantially the same terms and conditions as the proposed transfer. At any time within twenty
(20) days after the date of the receipt by the Company of the ROFR Notice, the Company shall have the right and option to purchase, or to arrange for a Subsidiary, third party or Affiliate to purchase, all (but not less than all) of the shares
of Stock proposed to be transferred to a ROFR Transferee, pursuant to Section 4(b). 
 (b) The Company shall have the right and option
to purchase, or to arrange for a Subsidiary, third party or Affiliate to purchase, all of the shares of Stock proposed to be transferred to any ROFR Transferee at a purchase price equal to the minimum price at which the Management Stockholder
proposes to transfer such Stock to any ROFR Transferee and otherwise on substantially the same terms and conditions as the proposed transfer (or, if the proposed transfer to any ROFR Transferee includes any consideration other than cash, then at the
sole option of the Company, at the equivalent all cash price, determined in good faith by the Board), by delivering (i) a certified bank check or checks in the appropriate amount (or by wire transfer of immediately available funds, if the
Management Stockholder Entities provide to the Company wire transfer instructions) and/or (ii) if the proposed transfer to any ROFR Transferee includes any consideration other than cash, any such non-cash consideration, in each case to be paid
to the Management Stockholder at the principal office of the Company against delivery of certificates or other instruments representing the shares of Stock so purchased, appropriately endorsed by the Management Stockholder. If at the end of the
20-day period, the Company has not tendered (or caused to be tendered) the purchase price for such shares in the manner set forth above, the Management Stockholder may, during the succeeding 60-day period, sell not less than all of the shares of
Stock proposed to be transferred to any ROFR Transferee (subject to compliance with the other terms of this Agreement) on terms no less favorable to the Management Stockholder than those contained in the ROFR Notice. Promptly after such sale, the
Management Stockholder shall notify the Company of the consummation thereof and shall furnish such evidence of the completion and time of completion of such sale and of the terms thereof as may reasonably be requested by the Company. If, at the end
of sixty (60) days following the expiration of the 20-day period during which the Company is entitled hereunder to purchase the Stock, the Management Stockholder has not completed the sale of such shares of the Stock as aforesaid, all of the
restrictions on sale, transfer or assignment contained in this Agreement shall again be in effect with respect to such shares of the Stock. 
  

 27 








 (c) Notwithstanding anything in this Agreement to the contrary, this Section 4 shall terminate and
be of no further force or effect upon the earlier of occurrence of a Change in Control or a Qualified Public Offering. 
 5. The

 (a) Except as otherwise provided herein, if the
Management Stockholder’s employment with the Company (or, if applicable, any of its Subsidiaries or Affiliates) terminates as a result of the death or Disability of the Management Stockholder, then the applicable Management Stockholder Entity,
shall, during the later of the following: (x) the 365-day period following the date of such termination for death or Disability or (y) if the Company has declared an Event (as defined below) has occurred, the 30-day period following the
date on which the Management Stockholder Entity receives notice that an Event which was declared by the Company while the Management Stockholder Entity held the Stock no longer exists; provided, however, the Management Stockholder
Entity shall not be entitled to exercise the Management Stockholder’s rights pursuant to this Section 5 unless the Management Stockholder Entity has held the Stock to be resold pursuant to this Section 5 for at least six
(6) months (including as a result of net settlement as specified in Section 5(a)(ii) (the “Put Period”), have the right to: 
 (i) With respect to Stock (including Net Settled Stock, defined below), sell to the Company, and the Company shall be required to purchase, on one occasion, all of the shares of Stock then held by the applicable
Management Stockholder Entities at a per share price equal to the Fair Market Value on the Repurchase Calculation Date; 
 (ii) With respect to any outstanding vested Options, upon the occurrence of the applicable event identified in this Section 5 giving rise to the Management Stockholder’s rights hereunder, the Company shall deem the Management
Stockholder Entity to have exercised the outstanding vested Options, in accordance with the terms of the relevant Stock Option Agreement, and be entitled to receive from the Company, on one occasion, in exchange for all of the outstanding vested
Options then held by the applicable Management Stockholder Entity, if any, a number of shares of Stock equal to the quotient of (x) the product of (A) the excess, if any, of the Fair Market Value on the Repurchase Calculation Date, over
the Option Exercise Price and (B) the number of shares then acquirable on exercise, divided by (y) the Fair Market Value on the Repurchase Calculation Date, which Options shall be terminated in exchange for such payment of shares of Stock
(such shares of Stock, the “Net Settled Stock”). In the event the foregoing amount is zero or a negative number, all outstanding exercisable Options shall be automatically terminated without any payment in respect thereof; and

 (iii) With respect to any outstanding unvested Options, all outstanding unvested Options shall be terminated and cancelled
without any payment in respect thereof. 
 (b) In the event the applicable Management Stockholder Entities intend to exercise their rights
pursuant to Section 5(a), such Management Stockholder Entities shall send written notice to the Company, at any time during the Put Period, of their intention to sell shares of Stock (including Net Settled Stock) in exchange for the payment
referred to in Section 5(a)(i) and shall indicate the number of shares of Stock (including Net Settled Stock)

Company, of a certified bank check or checks in the appropriate amount payable to the order of each of the applicable Management Stockholder Entities (or by wire transfer of immediately available funds, if the Management Stockholder Entities provide
to the Company wire transfer instructions) against delivery of certificates or other instruments representing the Stock so purchased. 
 (c)
Notwithstanding anything in this Section 5 to the contrary, if there exists and is continuing a default or an event of default on the part of the Company or any Subsidiary of the Company under any loan, guarantee or other agreement under which
the Company or any Subsidiary of the Company has borrowed money or if the repurchase referred to in Section 5(a) (or Section 6 below, as the case may be) would result in a default or an event of default on the part of the Company or any
Affiliate of the Company under any such agreement or if a repurchase would reasonably be expected to be prohibited by the Texas Business Organization Code (“TBOC”) or any federal or state securities laws or regulations (or if the
Company reincorporates in another state, the business corporation law of such state) (each such occurrence being an “Event”), the Company shall not be obligated to repurchase any of the Stock or the Options from the applicable
Management Stockholder Entities to the extent it would cause any such default or would be so prohibited by the Event for cash but instead, with respect to such portion with respect to which cash settlement is prohibited, may satisfy its obligations
with respect to the Management Stockholder Entities’ exercise of their rights under Section 5(a) by delivering to the applicable Management Stockholder Entity a note with a principal amount equal to the amount payable under this
Section 5 that was not paid in cash, having terms acceptable to the Company’s (and its Affiliate’s, as applicable) lenders and permitted under the Company’s (and its Affiliate’s, as applicable) debt instruments but which in
any event (i) shall be mandatorily repayable promptly and to the extent that an Event no longer prohibits the payment of cash to the applicable Management Stockholder Entity pursuant to this Agreement; and (ii) shall bear interest at a
rate equal to the effective rate of interest in respect of the Company’s U.S. dollar-denominated subordinated public debt securities (including any original issue discount). 
 (d) Notwithstanding anything in this Agreement to the contrary, this Section 5 shall terminate and be of no further force or effect upon the earlier
of (i) a Change in Control, or (ii) the later of (x) the fifth anniversary of the Closing Date or (y) the consummation of a Qualified Public Offering, except for any payment obligation of the Company or transfer obligation of the
Management Stockholder Entities which has arisen prior to such termination date. 
 (e) Notwithstanding the foregoing and subject to
Section 5(d), if an Event exists and is continuing for ninety (90) days after the date of the Redemption Notice, the Management Stockholder Entities shall be permitted by written notice to rescind any Redemption Notice with respect to that
portion of the Stock (including Net Settled Stock) repurchased by the Company from the Management Stockholder Entities pursuant to this Section 5 with the note described above, to the extent such note remains unpaid, and such repurchase shall
be rescinded; provided that, upon such rescission, such note shall be immediately canceled without any action on the part of the Company or the Management Stockholder Entities, and notwithstanding anything herein or in such note to the
contrary, the Company shall have no obligation to pay any amounts of principal or interest thereunder.

 6. The Company’s Option to Purchase Stock (including Net Settled Stock) and Options of the
Management Stockholder Upon Certain Terminations of Employment. 
 (a) Termination by the Management Stockholder without Good Reason.
If, prior to the fifth anniversary of the Closing Date the Management Stockholder’s active employment with the Company (or, if applicable, its Subsidiaries or Affiliates) is terminated by the Management Stockholder without Good Reason,
other than on account of death, Disability or Retirement (such event, a “Section 6(a) Call Event”), then: 
 (i) With respect to any Purchased Shares or Deferred Stock, the Company may purchase, on one occasion, all or any portion of the Purchased Shares or Deferred Stock then held by the applicable Management Stockholder Entities at a per share
purchase price equal to the Base Price (or, if higher, the Indirect Sale Price); 
 (ii) With respect to any Option Stock or
Net Settled Stock, the Company may purchase, on one occasion, all or any portion of the shares of such Option Stock or Net Settled Stock then held by the applicable Management Stockholder Entities at a per share purchase price equal to the Fair
Market Value of the Option Stock or Net Settled Stock less 20% of the amount, if any, by which such Fair Market Value exceeds exercise price paid for such Option Stock or Net Settled Stock (which exercise price shall be zero with respect to the Net
Settled Stock); 
 (iii) With respect to any outstanding vested Options, upon the occurrence of a Section 6(a) Call
Event, the Company shall deem the Management Stockholder Entity to have exercised the outstanding vested Options, in accordance with the terms of the relevant Stock Option Agreement, and be entitled to receive from the Company, on one occasion, Net
Settled Stock in exchange for all of the outstanding vested Options then held by the applicable Management Stockholder Entity; and 
 (iv) With respect to any outstanding unvested Options, all outstanding unvested Options shall be automatically terminated without any payment in respect thereof upon the occurrence of the Section 6(a) Call Event. 
 For the avoidance of any doubt, the termination of the Management Stockholder’s active employment with the Company (or, if applicable, its Subsidiaries or
Affiliates) by the Management Stockholder without Good Reason upon or following the fifth anniversary of the Closing Date shall not constitute a Section 6(a) Call Event with respect to Stock or Options. 
 (b) Termination for Cause by the Company and other Call Events. If at any time (i) the Management Stockholder’s active employment with
the Company (or, if applicable, its Subsidiaries or Affiliates) is terminated by the Company (or, if applicable, its Subsidiaries or Affiliates) for Cause or (ii) within 18 months following any termination of the Management Stockholder’s
employment with the Company (and/or, if applicable, its 

  

 30 








 
Subsidiaries or Affiliates), the Management Stockholder engages in a Competing Business (such event under item (ii), a “Section 6(b)(ii) Call
Event” and each event described above under items (i) and (ii), a “Section 6(b) Call Event”), then: 
 (i) With respect to Stock or Net Settled Stock (and in the case of a Section 6(b)(ii) Call Event, with respect to Option Stock only), the Company may purchase, on one occasion, all or any portion of the shares of
Stock then held by the applicable Management Stockholder Entities at a per share purchase price equal to the lesser of (x) Base Price (or other applicable price paid by such Management Stockholder Entities for such Stock) and (y) the Fair
Market Value of the Stock; and 
 (ii) With respect to any outstanding Options (whether vested or unvested), all outstanding
Options shall be automatically terminated without any payment in respect thereof upon the occurrence of the Section 6(b) Call Event. 
 (iii) Notwithstanding the foregoing, to the extent the Management Stockholder engages in a Section 6(b)(ii) Call Event after the Management Stockholder has exercised his or her outstanding Options and/or sold the
underlying Option Stock, Section 22(c) shall apply. 
 (c) Call Notice. The Company shall have a period (the “Call
Period”) of ninety (90) days following the later to occur of (A) the date of any Call Event and (B) (i) with respect to Option Stock and Net Settled Stock, the date on which the Management Stockholder Entity has held the
Stock most recently acquired to be sold pursuant to this Section 6 for at least six (6) months, or (ii) with respect to Purchased Shares or Deferred Stock, the date on which the Management Stockholder Entity has held the Stock most
recently acquired to be sold pursuant to this Section 6 for at least six (6) months following a termination for any reason other than a termination without Good Reason, in which to give notice in writing to the Management Stockholder of
its election to exercise its rights and obligations pursuant to this Section 6 (“Repurchase Notice”). The completion of the purchases pursuant to the foregoing shall take place at the principal office of the Company no later
than the fifteenth Business Day after the giving of the Repurchase Notice. The applicable Repurchase Price shall be paid by delivery to the applicable Management Stockholder Entities of a certified bank check or checks in the appropriate amount
payable to the order of each of the applicable Management Stockholder Entities (or by wire transfer of immediately available funds, if the Management Stockholder Entities provide to the Company wire transfer instructions) against delivery of
certificates or other instruments representing the Stock so purchased. For purposes of this Section 6, any determination of Fair Market Value shall be made as of the Repurchase Calculation Date. 
 (d) Use of Note to Satisfy Call Payment. Notwithstanding any other provision of this Section 6 to the contrary, if there exists and is
continuing any Event, the Company will, to the extent it has exercised its rights to purchase Stock pursuant to this Section 6, in order to complete the purchase of any Stock pursuant to this Section 6, deliver to the applicable Management
Stockholder Entities (i) a cash payment for any amounts payable pursuant to this Section 6 that would not cause an Event and (ii) a note having the same terms as that provided in Section 5(c) above with a principal amount equal
to the amount payable but not paid in cash pursuant to this Section 6 due to the Event. 

  

 31 








 
Notwithstanding the foregoing, if an Event exists and is continuing for ninety (90) days from the date of the Section 6(b) Call Event, the
Management Stockholder Entities shall be permitted by written notice to cause the Company to rescind any Repurchase Notice with respect to that portion of the Stock repurchased by the Company from the Management Stockholder Entities pursuant to this
Section 6 with the note described in the foregoing sentence, to the extent such note remains unpaid; provided that, upon such rescission, such repurchase shall be immediately rescinded and such note shall be immediately canceled without
any action on the part of the Company or the Management Stockholder Entities and, notwithstanding anything herein or in such note to the contrary, the Company shall have no obligation to pay any amounts of principal or interest thereunder.

 (e) Termination. Notwithstanding anything in this Agreement to the contrary, this Section 6 shall terminate and be of no
further force or effect upon the earlier of (i) a Change in Control, or (ii) the later of (x) the fifth anniversary of the Closing Date or (y) the consummation of a Qualified Public Offering, except for any payment obligation of
the Company or transfer obligation of the Management Stockholder Entities which has arisen prior to such termination date.

 38 








 
of the Coordination Committee of Parent or the Company) without registration under the Exchange Act within the limitations of the exemptions provided by

 9.
“Piggyback” Registration Rights. Effective after the occurrence of an initial Public Offering: 
 (a) The Parties agree to be
bound by all of the terms, conditions and obligations of the Registration Rights Agreement as they relate to the exercise of piggyback registration rights as provided in Sections 3, 4, 5, 6, 7, 8 and 12 of the Registration Rights Agreement (the
“Piggyback Registration Rights”) as in effect on the date hereof (subject, with respect to any such Management Stockholder provided Piggyback Registration Rights, only to any amendments thereto to which such Management Stockholder
has agreed in writing to be bound), and, if any member of the Sponsor Group is selling stock, the Management Stockholder shall have all of the rights and privileges of the Piggyback Registration Rights (including, without limitation, the right to
participate in the Public Offering and any rights to indemnification and/or contribution from the Company and/or the Sponsor Group), in each case as if the Management Stockholder were an original party (other than the Company) to the Registration
Rights Agreement, subject to applicable and customary underwriter restrictions; provided, however, that at no time shall the Management Stockholder have any rights to request registration under Section 3 of the Registration Rights
Agreement. All Stock purchased or held by the applicable Management Stockholder Entities pursuant to this Agreement shall be deemed to be “Registrable Securities” as defined in the Registration Rights Agreement. 
 (b) In the event of a proposed registration of Common Stock by any member of the Sponsor Group in accordance with the terms of the Registration Rights
Agreement, the Company will, within ten days after receipt of such demand notice, notify each Management Stockholder in writing (a “Piggyback Notice”) of such proposed registration (a “Proposed Registration”),
offering, subject to the limitations in this Section 9 and the Registration Rights Agreement, to include in such registration shares of Stock held by such Management Stockholder. If within fifteen (15) days after such Piggyback Notice is


  

 39 








 
given to the Management Stockholder, the Company receives from the applicable Management Stockholder Entities a written request (a
“Request”) to include shares of Stock held by the applicable Management Stockholder Entities in such registration (which Request will be irrevocable unless otherwise mutually agreed to in writing by the Management Stockholder and
the Company), subject to subsections 9(c) and (d) below, the Company shall include in such registration (if ultimately completed), shares of Stock properly and timely requested to be included in such Request. 
 (c) The maximum number of shares of Stock which will be registered pursuant to a Request will be the lowest of (i) the number of shares of Stock
then held by the Management Stockholder Entities, including all shares of Stock which the Management Stockholder Entities are then entitled to acquire under an unexercised Option to the extent then exercisable, multiplied by a fraction, the
numerator of which is the aggregate number of shares of Stock being registered by holders of Registrable Securities and the denominator of which is the aggregate number of shares of Stock owned by the holders of Registrable Securities or
(ii) the maximum number of shares of Stock which the Company can register in connection with such Request in the Proposed Registration without adverse effect on the registration or offering in the view of the managing underwriters (reduced pro
rata as more fully described in subsection (d) of this Section 9) and (iii) the maximum number of shares which the Management Stockholder (pro rata based upon the aggregate number of shares of Stock the Management Stockholder and all
Other Management Stockholders have requested to be registered) is permitted to register under the Piggyback Registration Rights. 
 (d) If a
Proposed Registration involves an underwritten offering and the managing underwriter advises the Company in writing that in its view the total number or dollar amount of shares of Stock proposed to be sold in such offering is such as to adversely
affect the success of such offering, then there shall be included in such underwritten offering the number or dollar amount of shares of Registrable Securities that in the opinion of such managing underwriter can be sold without adversely affecting
such offering. To the extent that pursuant to the Registration Rights Agreement any such reduction in the number of shares of Registrable Securities to be included in such underwritten offering results in reduction to the number of shares to be
registered in such Proposed Registration by the selling holders of Registrable Securities (as defined in the Registration Rights Agreement), the Management Stockholder and all Other Management Stockholders and any other Persons who are entitled to
piggyback or incidental registration rights in respect of Registrable Securities (together, the “Holders”), the number of shares of Stock included in the Proposed Registration by Holders, shall be allocated pro rata among all
requesting Holders on the basis of the relative number of shares of Registrable Securities requested to be included in such Proposed Registration by each such Holder. 
 (e) Upon delivering a Request a Management Stockholder having Piggyback Registration Rights pursuant to clause (b) of this Section 9 will, if requested by the Company, execute and deliver a custody agreement
and power of attorney having customary terms and in form and substance reasonably satisfactory to the Company with respect to the shares of Stock to be registered pursuant to this Section 9 (a “Custody Agreement and Power of
Attorney”). The Custody Agreement and Power of Attorney will provide, among other things, that the Management Stockholder will deliver to and deposit in custody with the custodian and attorney-in-fact named therein a certificate or
certificates (to the extent applicable) representing such shares of Stock (duly endorsed in blank by the registered owner or owners thereof or accompanied by duly executed stock powers in blank) and irrevocably 

  

 40 








 
appoint said custodian and attorney-in-fact as the Management Stockholder’s agent and attorney-in-fact with full power and authority to act under the
Custody Agreement and Power of Attorney on the Management Stockholder’s behalf with respect to the matters specified therein. 
 (f) The
Management Stockholder agrees that he will execute such other agreements as the Company may reasonably request to further evidence the provisions of this Section 9, including reasonable and customary lock-up agreements consistent with the
requirements of the Registration Rights Agreement; provided that Parent and its Affiliates that own Common Stock in the Company enter into a similar agreement. 
 (g) This Section 9 will terminate on the earlier of (i) the occurrence of a Change in Control and (ii) with respect to each Management Stockholder, on the date on which such Management Stockholder
ceases to own any Registrable Securities. 
 10. Rights to Negotiate Repurchase Price. Nothing in this Agreement shall be deemed to
restrict or prohibit the Company from purchasing, redeeming or otherwise acquiring for value shares of Stock or Options from the Management Stockholder, at any time, upon such terms and conditions, and for such price, as may be mutually agreed upon
in writing between the Parties, whether or not at the time of such purchase, redemption or acquisition circumstances exist which specifically grant the Company the right to purchase, or the Management Stockholder the right to sell, shares of Stock
or any Options under the terms of this Agreement; provided that no such purchase, redemption or acquisition shall be consummated, and no agreement with respect to any such purchase, redemption or acquisition shall be entered into, without the
prior approval of the Board. 
 11. Notice of Change of Beneficiary. Immediately prior to any transfer of Stock to a Management
Stockholder’s Trust, the Management Stockholder shall provide the Company with a copy of the instruments creating the Management Stockholder’s Trust and with the identity of the beneficiaries of the Management Stockholder’s Trust. The
Management Stockholder shall notify the Company as soon as practicable prior to any change in the identity of any beneficiary of the Management Stockholder’s Trust. 
 12. Recapitalizations, etc. The provisions of this Agreement shall apply, to the full extent set forth herein with respect to the Stock or the Options, to any and all shares of capital stock of the Company or
any capital stock, partnership units or any other security evidencing ownership interests in any successor or assign of the Company (whether by merger, consolidation, sale of assets or otherwise) which may be issued in respect of, in exchange for,
or substitution of the Stock or the Options by reason of any stock dividend, split, reverse split, combination, recapitalization, liquidation, reclassification, merger, consolidation or otherwise. 
 13. Management Stockholder’s Employment by the Company. Nothing contained in this Agreement (a) obligates the Company or any Subsidiary
of the Company to employ the Management Stockholder in any capacity whatsoever or (b) prohibits or restricts the Company (or any such Subsidiary) from terminating the employment of the Management Stockholder at any time or for any reason
whatsoever, with or without Cause, and the Management Stockholder hereby acknowledges and agrees that neither the Company nor any other person has made any representations or promises whatsoever to the Management Stockholder concerning the
Management Stockholder’s employment or continued employment by the Company or any Subsidiary of the Company. 
  

 41 








 14. Binding Effect. The provisions of this Agreement shall be binding upon and accrue to the
benefit of the parties hereto and their respective heirs, legal representatives, successors and assigns. In the case of a transferee permitted under clauses (2), (3) or (4) of Section 2(a) or clauses (ii) and (v) of
Section 3(a) hereof, such transferee shall be deemed the Management Stockholder hereunder; provided, however, that no transferee (including without limitation, transferees referred to in Section 2(a) or Section 3(a)
hereof) shall derive any rights under this Agreement unless and until such transferee has delivered to the Company a valid undertaking and becomes bound by the terms of this Agreement. No provision of this Agreement is intended to or shall confer
upon any Person other than the Parties any rights or remedies hereunder or with respect hereto. 
 15. Amendment. This Agreement may
be amended by the Company at any time; provided that any amendment (i) that materially disadvantages the Management Stockholder shall not be effective unless and until the Management Stockholder has consented thereto in writing and
(ii) that disadvantages the Management Stockholders in more than a de minimis way but less than a material way shall require the consent of Management Stockholders holding a majority of the equity interests held by the Management Stockholders.

 16. Closing. Except as otherwise provided herein, the closing of each purchase and sale of shares of Stock pursuant to this
Agreement shall take place at the principal office of the Company on the tenth Business Day following delivery of the notice by either Party to the other of its exercise of the right to purchase or sell such Stock hereunder. 
 17. Applicable Law; Jurisdiction; Arbitration; Legal Fees. 
 (a) The laws of the State of Texas applicable to contracts executed and to be performed entirely in such state shall govern the interpretation, validity and performance of the terms of this Agreement. 
 (b) In the event of any controversy among the parties hereto arising out of, or relating to, this Agreement which cannot be settled amicably by the
parties, such controversy shall be finally, exclusively and conclusively settled by mandatory arbitration conducted expeditiously in accordance with the American Arbitration Association rules by a single independent arbitrator. Such arbitration
process shall take place in Dallas, Texas. The decision of the arbitrator shall be final and binding upon all parties hereto and shall be rendered pursuant to a written decision, which contains a detailed recital of the arbitrator’s reasoning.
Judgment upon the award rendered may be entered in any court having jurisdiction thereof. 
 (c) Notwithstanding the foregoing, the
Management Stockholder acknowledges and agrees that the Company, its Subsidiaries, the Sponsor Group and any of their respective Affiliates shall be entitled to injunctive or other relief in order to enforce the covenant not to compete, covenant not
to solicit and/or confidentiality covenants as set forth in Section 22(a) of this Agreement. 
 (d) In the event of any arbitration or
other disputes with regard to this Agreement or any other document or agreement referred to herein, each Party shall pay its own legal fees and expenses, unless otherwise determined by the arbitrator. 
  

 42 








 18. Assignability of Certain Rights by the Company. The Company shall have the right to assign any
or all of its rights or obligations to purchase shares of Stock pursuant to Sections 4, 5 and 6 hereof; provided, however, that no such assignment shall relieve the Company from its obligations thereunder. 
 19. Miscellaneous. 
 (a) In this
Agreement all references to “dollars” or “$” are to United States dollars and the masculine pronoun shall include the feminine and neuter, and the singular the plural, where the context so indicates.

shall not be affected, but shall remain in full force and effect. 
 20. Withholding. The Company or its Subsidiaries shall have the
right to deduct from any cash payment made under this Agreement to the applicable Management Stockholder Entities any federal, state or local income or other taxes required by law to be withheld with respect to such payment, if applicable.

 22. Confidential Information; Covenant Not to Compete; Covenant Not to Solicit. 
 (a) In consideration of the Company entering into this Agreement with the Management Stockholder and hereby promising and committing itself to provide the
Management Stockholder with Confidential Information and/or specialized training after the Management Stockholder executes this Agreement, unless there exists any covenant that pertains to the same subject matter as set forth in this Section 22
in any employment agreement or change in control agreement in effect at the time of termination of employment between the Management Stockholder and the Company or any of its Subsidiaries or Affiliates, in which case such covenants shall supersede
the covenants contained in this Section 22; then the Management Stockholder shall be subject to the covenants contained in this Section 22. Subject to the preceding sentence, the Management Stockholder shall not, directly or indirectly:

 (i) at any time during or after the Management Stockholder’s employment with the Company or its Subsidiaries,
disclose any Confidential Information pertaining to the business of the Company or any of its Subsidiaries or the Sponsor Group or any of their respective Affiliates, except when required to perform his or her duties to the Company or one of its
Affiliates, or by law or judicial process, provided that the Management Stockholder gives the Company reasonable notice of any legal or judicial proceeding requiring the Management Stockholder to disclose Confidential Information and an opportunity
to challenge the disclosure of any such information, and the Management Stockholder agrees to provide such reasonable notice in writing to: 
 General Counsel 
 Energy Future Holdings Corp. 
 1601 Bryan Street, 6th Floor 
 Dallas, Texas 75201 
 (214) 812-6032 (facsimile); 
 (ii) at any time during the Management Stockholder’s
employment with the Company or its Subsidiaries and for a period of eighteen 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 Parent, any of its Subsidiaries, or the Company operates or conducts business; or 
 (iii) at any time during the Management Stockholder’s employment with the Company or its Subsidiaries and for a period of
eighteen months thereafter, directly or indirectly (A) solicit customers or clients of the Company or any of its Subsidiaries to terminate their relationship with the Company or any of its Subsidiaries or otherwise solicit such customers or
clients to compete with any business of the Company, or its Subsidiaries, 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 the
Management Stockholder’s employment employed by the Company or any of its Subsidiaries; 
  

 44 








 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 business that directly or indirectly competes, at the relevant determination date, with one or more of the businesses of the Company, or its Subsidiaries. If the Management
Stockholder is bound by any other agreement with the Company regarding the use or disclosure of Confidential Information, the provisions of this Agreement shall be read in such a way as to further restrict and not to permit any more extensive use or
disclosure of Confidential Information. Notwithstanding the foregoing, for the purposes of Section 22(a)(ii), (A) the Management Stockholder may, directly or indirectly own, solely as an investment, securities of any Person engaged in the
business of the Company or its Affiliates which are publicly traded on a national or regional stock exchange or quotation system or on the over-the-counter market if the Management Stockholder (I) is not a controlling person of, or a member of
a group which controls, such person and (II) does not, directly or indirectly, own 5% or more of any class of securities of such Person, and (B) the Non-Compete Period shall not be triggered by any exercise of tag-along rights under the Sale
Participation Agreement or Drag Transaction that may occur after the date hereof. 
 (b) Notwithstanding clause (a) above, if at any
time a court holds that the restrictions stated in such clause (a) are unreasonable or otherwise unenforceable under circumstances then existing, the parties hereto agree that the maximum period, scope or geographic area determined to be
reasonable under such circumstances by such court will be substituted for the stated period, scope or area. Because the Management Stockholder’s services are unique and because the Management Stockholder has had access to Confidential
Information, the parties hereto agree that money damages will be an inadequate remedy for any breach of this Agreement (except with respect to any violation of provisions of Section 22(a)(ii)). In the event of a breach or threatened breach of
this Agreement, the Company or its successors or assigns may, in addition to other rights and remedies existing in their favor, apply to any court of competent jurisdiction for specific performance and/or injunctive relief in order to enforce, or
prevent any violations of, the provisions hereof (without the posting of a bond or other security). 
 (c) In the event that the Management
Stockholder engages in activity giving rise to a Section 6(b)(ii) Call Event or breaches any of the provisions of Sections 22(a)(ii) or 22(a)(iii), the Management Stockholder shall be required to pay to the Company any amounts actually
paid to him or her or otherwise received in respect of any repurchase or disposition of any Options or Option Stock (including Net Settled Stock) held by such Management Stockholder; provided that with respect to Option Stock (including Net
Settled Stock), the Management Stockholder shall be required to pay to the Company only such amounts, if any, that the Management Stockholder received in excess of the exercise or purchase price paid by the Management Stockholder in acquiring such
Stock, on a net after-tax basis; provided further, in the event the Management Stockholder engages in activity giving rise to a Section 6(b)(ii) Call Event (to the extent the provisions of Section 6(b)(iii) are applicable) or
breaches any of the provisions of Section 22(a)(ii), the provisions of this Section 22(c) shall be the Company’s sole remedy. 
 23. Irrevocable Proxy. Subject to and to the extent permitted by the laws of the State of Texas, each Management Stockholder hereby irrevocably appoints Parent and any authorized representatives and designees thereof as its lawful
proxy and attorney-in-fact to 

  

 45 








 
exercise with full power in such Management Stockholder’s name and on its behalf such Management Stockholder’s right to vote all of the shares of
outstanding Common Stock owned by the Management Stockholder at any regular or special meeting of the stockholders of the Company for the express purpose of electing any one or more members to the Board or approving any Change in Control transaction
or agreement. If voting under such proxy Parent and any authorized representatives and designees thereof shall vote under this proxy on behalf of each such Management Stockholder in the same manner as Parent votes any outstanding shares of Common
Stock owned by it at any such regular or special meeting of the stockholders of the Company for the express purpose of electing any one or more members to the Board or approving any Change in Control transaction or agreement. This proxy is
irrevocable and is coupled with an interest and shall not be terminable as long as this Agreement remains effective among the parties hereto, their successors, transferees and assigns and, if such Management Stockholder is a natural person, shall
not terminate on the disability or incompetence of such Management Stockholder. The Company is hereby requested and directed to honor this proxy upon its presentation by Parent and any authorized representatives and designees thereof, without
any duty of investigation whatsoever on the part of the Company. Each such Management Stockholder agrees that the Company, and the Company’s secretary shall not be liable to such Management Stockholder for so honoring this proxy. This
Section 23 shall terminate and be of no further force or effect upon the later of (x) the fifth anniversary of the Closing Date or (y) the consummation of a Qualified Public Offering.

 Exhibit IV 
 Sale Participation Agreement 
 SLT Form 
 July 1, 2008 
  

	To:	The Person whose name is 

 set forth on the signature page
hereof 
 Dear Sir or Madam: 
 Concurrently with
entering into this letter agreement, you are entering into a Management Stockholder’s Agreement with Energy Future Holdings Corp., a Texas corporation formerly known as “TXU Corp.” (the “Company”) and Texas Energy
Future Holdings Limited Partnership, a Delaware limited partnership (“Parent”) (the “Management Stockholder’s Agreement”) relating to (i) the grant by the Company to you of new options (the
“Options”) to purchase shares of the Company’s common stock, no par value (the “Common Stock”), and (ii) the grant by the Company to you of deferred share units (“Deferred Share Units”)
representing your right to receive shares of Common Stock at a future time. 
 Parent hereby agrees with you as follows: 
 1. (a) In the event that at any time on or after the date hereof (i) Parent or (ii) any member of the Sponsor Group (as defined in the
Management Stockholder’s Agreement) solely to the extent that such member of the Sponsor Group is selling limited partnership units of Parent (“LP Units”) in connection with a sale (or series of related sales) of outstanding LP
Units to a transferee that is not an Affiliate of any member of the Sponsor Group and other than such sales (or series of related sales) prior to December 31, 2009 that do not exceed the Indirect Sale Threshold (as defined below) (each a
“Selling Entity”) proposes to sell directly for cash or any other consideration (x) in the case of clause (i) any shares of Common Stock owned by Parent and (y) in the case of clause (ii) any LP Units, in any
transaction other than a Public Offering (as defined in the Management Stockholder’s Agreement) or a sale, directly or indirectly, to an Affiliate of Parent, then, unless such Selling Entity is entitled to and does exercise the drag-along
rights pursuant to Paragraph 7 below and a Drag Transaction (as defined below) is consummated, Parent will notify you or your Management Stockholder’s Estate or Management Stockholder’s Trust (as such terms are defined in the Management
Stockholder’s Agreement, and collectively with you, the “Management Stockholder Entities”), as the case may be, in writing (a “Notice”) of such proposed sale (a “Proposed Sale”) specifying the
principal terms and conditions of the Proposed Sale (the “Material Terms”) including (A) the number of Shares of Common Stock or LP Units proposed to be included in the Proposed Sale, (B) the percentage of the outstanding
Common Stock or LP Units at the time the Notice is given that is represented by the number of shares of Common Stock or LP Units proposed to be included in the Proposed Sale, (C) the price per share of Common Stock subject to the Proposed Sale
(where the event 








 
triggering the Notice is a sale of LP Units, such price per share of Common Stock shall be deemed to be equal to the price per LP Unit subject to the
proposed sale, subject to equitable adjustment for stock or unit dividends or splits, recapitalizations or similar events), including a description of any pricing formulae and of any non-cash consideration sufficiently detailed to permit the
valuation thereof, (D) the Tag Along Sale Percentage (as defined below) of the Selling Entity and (E) the name and address of the Person (as defined in the Management Stockholder’s Agreement) to whom the Common Stock or LP Units is
proposed to be sold. 
 “Indirect Sale Threshold” means (1) prior to December 31, 2008, any sales of LP Units
that, together with prior sales of LP Units to a transferee that is not an Affiliate of any member of the Sponsor Group, are of less than 50% of the LP Units, and that are at a cash price of less than 120% of the Base Price, and (2) from
December 31, 2008 through December 31, 2009, any sales of LP Units that, together with other sales of LP Units from December 31, 2008 through December 31, 2009 to a transferee that is not an Affiliate of any member of the Sponsor
Group, are of less than 20% of the LP Units, and that for all such sales prior to December 31, 2009 under clause (1) and this clause (2) are less than 50% of the LP Units in the aggregate, and that are at a cash price of less than
120% of the Base Price. 
 (b) If, within 10 Business Days after the delivery of Notice under Paragraph 1(a), Parent receives from a
Management Stockholder Entity a written request (a “Request”) to include Common Stock held by such Management Stockholder Entity in the Proposed Sale (which Request shall be irrevocable except (a) as set forth in clauses
(c) and (d) of this Paragraph 1 below or (b) if otherwise mutually agreed to in writing by the Management Stockholder Entity and Parent), the Common Stock held by such Management Stockholder Entities plus (i) all shares of Common
Stock which you are then entitled to acquire under any unexercised portion of Options, to the extent such Option is then exercisable or would become exercisable as a result of the consummation of the Proposed Sale, and (ii) all shares of Common
Stock subject to the Deferred Share Units that are deliverable to you as a result of the consummation of the Proposed Sale (not in any event, other than as provided for below in Paragraph 2(a) in respect of the first (if any) Proposed Sale of LP
Units that exceeds the Indirect Sale Threshold, to exceed the Tag Along Sale Percentage of the Selling Entity multiplied by the total number of shares of Common Stock held by the Management Stockholder Entities in the aggregate, including all shares
of Common Stock which you are then entitled to acquire under any unexercised portion of Options, to the extent such Option is then exercisable or would become exercisable as a result of the consummation of the Proposed Sale, and all shares of Common
Stock subject to the Deferred Share Units) will be so included as provided herein. Promptly after the execution of the definitive sale agreement, if any, for such Proposed Sale (the “Sale Agreement”), Parent will furnish each
Management Stockholder Entity with a copy of the Sale Agreement, if any. For purposes of this Agreement, the “Tag Along Sale Percentage” shall mean the fraction, expressed as a percentage, determined by dividing the number of shares
of Common Stock or LP Units, as applicable, to be purchased from the Selling Entity by the total number of shares of Common Stock or LP Units, as applicable, owned directly by the Selling Entity. 
 (c) Notwithstanding anything to the contrary contained in this Agreement, if any of the economic terms of the Proposed Sale change, including without
limitation if the per share price will be less than the per share price disclosed in the Notice, or any of the other principal terms or conditions will be materially less favorable to the selling Management

Stockholder Entities than those described in the Notice, Parent will provide written notice thereof to each Management Stockholder Entity who has made a
Request and each such Management Stockholder Entity will then be given an opportunity to withdraw the offer contained in such holder’s Request (by providing prompt (and in any event within five (5) Business Days; provided that,
notwithstanding the foregoing, if the proposed closing with respect to the Proposed Sale is to occur within five (5) Business Days or less, no later than three (3) Business Days prior to such closing) written notice of such withdrawal to
Parent), whereupon such withdrawing Management Stockholder Entity will be released from all obligations thereunder. 
 (d) If the Selling
Entity does not complete the Proposed Sale by the end of the 120th day following the date of the effectiveness of the Notice, each selling Management Stockholder Entity may elect on or prior to such date to be released on and after such date from
all obligations under the applicable Request by notifying Parent and any Selling Entity (if not Parent) in writing of its desire to so withdraw. Upon receipt of that withdrawal notice, the Notice of the relevant Management Stockholder Entity shall
be null and void, and it will then be necessary for a separate Notice to be furnished, and the terms and provisions of clauses (a) and (b) of this Paragraph 1 separately complied with, in order to consummate such Proposed Sale pursuant to
this Paragraph 1, unless the failure to complete such Proposed Sale resulted from any failure by any selling Management Stockholder Entity to comply with the terms of this Paragraph 1. 
 (e) Notwithstanding anything to the contrary in the foregoing provisions of this Paragraph 1, the Selling Entity may, in its sole discretion, decide
whether or not to pursue, consummate, postpone or abandon the Proposed Sale and the terms and conditions thereof. None of the Company, the Selling Entities or any of their respective Affiliates shall have any liability to any Management Stockholder
Entity arising from, relating to or in connection with the pursuit, consummation, postponement, abandonment or terms and conditions of any such Proposed Sale. 
 2. (a) The number of shares of Common Stock that you will be permitted to include in a Proposed Sale pursuant to a Request will be the lesser of (A) the number of shares of Common Stock that you have offered
to sell in the Proposed Sale as set forth in the Request and (B) the product of (i) the aggregate number of shares of Common Stock or LP Units, as applicable, to be included in the Proposed Sale multiplied by (ii) a fraction
the numerator of which is the number of shares of Common Stock owned by you plus all shares of Common Stock which you are then entitled to acquire under any unexercised portion of Options, to the extent such Option is then exercisable or
would become exercisable as a result of the consummation of the Proposed Sale plus all shares of Common Stock subject to the Deferred Share Units, and the denominator of which is the total number of shares of Common Stock owned by you and all
other Persons participating in such sale as tag-along sellers pursuant to Other Management Stockholders Agreements (as defined in the Management Stockholder’s Agreement) or other agreements (all such other participants, the “Tag Along
Sellers”) plus the total number of shares of Common Stock which you and such Tag Along Sellers are then entitled to acquire under any unexercised portion of Options, to the extent such Options are then exercisable or would become
exercisable as a result of the consummation of the Proposed Sale, plus the total number of Common Stock subject to the Deferred Share Units held by you and such Tag Along Sellers, plus all shares of Common Stock or LP Units, as
applicable, owned by Parent; provided, that in 

  

 3 








 
the case of either of (A) or (B) above, for the first (if any) Proposed Sale of LP Units that exceeds the Indirect Sale Threshold, the number of
shares of Common Stock you will be permitted to include shall be increased by the number of shares of Common Stock that you would have been entitled to include in all prior sales of LP Units that would have been Proposed Sales if they had exceeded
the Indirect Sale Threshold, calculated as if those sales of LP Units had exceeded the Indirect Sale Threshold and were subject to these tag-along provisions. Each Tag Along Seller shall be permitted to conditionally exercise then-exercisable
Options such that if the Proposed Sale in not consummated, such exercise shall be void and such Options shall remain exercisable on the same terms and conditions as prior to such conditional exercise. 
 (b) If one or more Tag Along Sellers elect not to include the maximum number of shares of Common Stock which such Tag Along Seller would have been
permitted to include in a Proposed Sale pursuant to Paragraph 2(a) (such non-included shares, the “Eligible Shares”), then you and each of the remaining Tag Along Sellers, or any of them, will have the right to sell in the Proposed
Sale a number of additional shares of Common Stock equal to your pro rata portion of the number of Eligible Shares, based on the relative number of shares of Common Stock then held by you and each such Tag Along Seller plus all shares of
Common Stock which you and such Tag Along Seller are then entitled to acquire under any unexercised portion of the Option, to the extent such Option is then exercisable or would become exercisable as a result of the consummation of the Proposed
Sale, plus the total number of Common Stock subject to the Deferred Share Units held by you and such Tag Along Sellers. Such additional shares of Common Stock which you and such Tag Along Seller propose to sell shall not be included in any
calculation made pursuant to Paragraph 2(a) for the purpose of determining the number of shares of Common Stock which you will be permitted to include in a Proposed Sale. Notwithstanding any of the foregoing, the Selling Entity will have the
right to sell in the Proposed Sale additional shares of Common Stock or LP Units, as applicable, owned by it equal to the number, if any, of the total remaining Eligible Shares, which will not be included in any calculation made pursuant to
Paragraph 2(a) for the purpose of determining the number of shares of Common Stock which you will be permitted to include in a Proposed Sale. 
 3. Except as may otherwise be provided herein, shares of Common Stock subject to a Request will be included in a Proposed Sale pursuant hereto and in any agreements with purchasers relating thereto on the same terms and subject to the same
conditions applicable to the shares of Common Stock or LP Units which the Selling Entity proposes to sell in the Proposed Sale. Such terms and conditions shall include, without limitation: the sale price; the payment of fees, commissions and
expenses; the provision of, and customary representations and warranties as to, information reasonably requested by the Selling Entity covering matters regarding the Management Stockholder Entities’ ownership of shares; and the provision of
requisite indemnification; provided that any indemnification provided by the Management Stockholder Entities shall be pro rata in proportion with the number of shares of Common Stock or LP units to be sold; provided, further,
that no Management Stockholder Entity shall be required to (x) indemnify any Person for an amount, in the aggregate, in excess of the gross proceeds received in such Proposed Sale, or (y) agree to any non-compete or non-solicit provisions
that are more restrictive than such similar agreement between the Company and the applicable Management Stockholder. Notwithstanding anything to the contrary in the foregoing, if the consideration payable for shares of Common Stock is securities and
the acquisition of such securities by a Management Stockholder Entity would reasonably be expected to be prohibited under U.S., 

  

 4 








 
foreign or state securities laws, such Management Stockholder Entity shall be entitled to receive an amount in cash equal to the value of any such securities
such Person would otherwise be entitled to receive. 
 4. Upon delivering a Request, the Management Stockholder Entities will, if requested
by Parent, execute and deliver a custody agreement and power of attorney in form and substance reasonably satisfactory to Parent with respect to the shares of Common Stock which are to be sold by the Management Stockholder Entities pursuant hereto
(a “Custody Agreement and Power of Attorney”). The Custody Agreement and Power of Attorney will contain customary provisions and will provide, among other things, that the Management Stockholder Entities will deliver to and deposit
in custody with the custodian and attorney-in-fact named therein a certificate or certificates (if such shares are certificated) representing such shares of Common Stock (duly endorsed in blank by the registered owner or owners thereof) and
irrevocably appoint said custodian and attorney-in-fact as the Management Stockholder Entities’ agent and attorney-in-fact with full power and authority to act under the Custody Agreement and Power of Attorney on the Management Stockholder
Entities’ behalf with respect to the matters specified therein. 
 5. Your right pursuant hereto to participate in a Proposed Sale shall
be contingent on your material compliance with each of the provisions hereof and your willingness to execute such documents in connection therewith as may be reasonably requested by the Selling Entity. 
 6. If the consideration to be paid in exchange for shares of Common Stock in a Proposed Sale pursuant to Paragraph 1 includes any securities, and the
receipt thereof by the Selling Entity and a Management Shareholder Entity would require under applicable law (a) the registration or qualification of such securities or of any Person as a broker or dealer or agent with respect to such
securities or (b) the provision to any selling Management Shareholder Entity of any information regarding the Company, its subsidiaries, such securities or the issuer thereof that would not be required to be delivered in an offering solely to a
limited number of “accredited investors” under Regulation D promulgated under the Securities Act of 1933, as amended, and the rules and regulations in effect thereunder, the Selling Entity and such Management Shareholder Entity shall not,
subject to the following sentence, have the right to sell shares of Common Stock in such proposed sale. In such event, the Selling Entity shall have the right to cause to be paid to such selling Management Shareholder Entity in lieu thereof, against
surrender of the shares of Common Stock which would have otherwise been sold by such selling Management Shareholder Entity to the prospective buyer in the proposed sale, an amount in cash equal to the Fair Market Value (as defined in the Management
Stockholder’s Agreement) of such shares of Common Stock as of the date such securities would have been issued in exchange for such shares of Common Stock. 
 7. (a) If any Selling Entity that directly owns shares of Common Stock or LP Units proposes to transfer, directly or indirectly (whether by means of a merger, consolidation, reorganization or recapitalization,
sale, transfer or otherwise), a number of shares of Common Stock or LP Units equal to 50% or more of the outstanding Common Stock or LP Units, as applicable (such Person, the “Drag-Along Purchaser”), then if requested by such
Selling Entity, each Management Stockholder Entity shall be required to sell a number of shares of Common 

  

 5 








 
Stock equal to the aggregate number of shares of Common Stock held by the Management Stockholder Entities (including shares of Common Stock underlying
exercisable Options and Deferred Share Units) multiplied by the Tag Along Sale Percentage (such transaction, a “Drag Transaction”). 
 (b) Shares of Common Stock held by the Management Stockholder Entities included in a Drag Transaction will be included in any agreements with the Drag-Along Purchaser relating thereto on the same terms and subject to
the same conditions applicable to the shares of Common Stock or LP Units, as applicable, which the Drag-Along Purchaser proposes to sell in the Drag Transaction. Such terms and conditions shall include, without limitation: the pro rata reduction of
the number of shares of Common Stock or LP Units to be sold by the Drag-Along Purchaser and the Management Stockholder Entities to be included in the Drag Transaction if required by the Drag-Along Purchaser; the sale price; the payment of fees,
commissions and expenses; the provision of, and representation and warranty as to, information reasonably requested by the Drag-Along Purchaser covering matters regarding the Management Stockholder Entities’ ownership of shares of Common Stock;
and the provision of requisite indemnification; provided that any indemnification provided by the Management Stockholder Entities shall be pro rata in proportion with the number of shares of Common Stock or LP Units to be sold;
provided, further, that no Management Stockholder Entity shall be required to (x) indemnify any Person for an amount, in the aggregate, in excess of the gross proceeds received in such Proposed Sale, or (y) agree to any
non-compete or non-solicit provisions that are more restrictive than such similar agreement between the Company and the applicable Management Stockholder. 
 (c) Your pro rata share of any amount to be paid pursuant to Paragraph 3 or 7(b) shall be based upon the number of shares of Common Stock intended to be transferred by the Management Stockholder Entities plus the
number of shares of Common Stock you would have the right to acquire under any unexercised portion of the Option which is then vested or would become vested as a result of the Proposed Sale or Drag Transaction, assuming that you receive a payment in
respect of such Option. 
 (d) Notwithstanding anything to the contrary in the foregoing, if the consideration payable to Management
Stockholder Entities for shares of Common Stock is securities and the acquisition of such securities by a Management Stockholder Entity would reasonably be expected to be prohibited under U.S., foreign or state securities laws, such Management
Stockholder Entity shall be entitled to receive an amount in cash equal to the value of any such securities such Person would otherwise be entitled to receive. 
 8. The obligations of Parent hereunder shall extend only to you and your transferees (“Permitted Transferees”) who (a) are party to a Stockholder’s Agreement with the Company and
(b) have acquired Common Stock pursuant to clause (ii) of the definition of a Permitted Transfer (as defined in the Management Stockholder’s Agreement), and none of the Management Stockholder Entities’ successors or assigns, with
the exception of any Permitted Transferee and only with respect to the Common Stock acquired by such Permitted Transferee pursuant to a Permitted Transfer, shall have any rights pursuant hereto. 
 9. This Agreement shall terminate and be of no further force and effect on the occurrence of the earlier of (A) the consummation of a Qualified
Public Offering (as defined in the Management Stockholder’s Agreement) and (B) the later of the fifth anniversary of the Closing Date and a Change in Control (as defined in the Management Stockholder’s Agreement).

Stockholders holding a majority of the equity interests held by the Management Stockholders.

 Exhibit V 
 Paragraph 1. In the event it shall be determined that any payment, benefit or distribution (or combination thereof) by the Company, any of its affiliates, or one or more trusts established by the Company or any of its affiliates for
the benefit of their employees, to or for the benefit of Executive (whether paid or payable or distributed or distributable pursuant to the terms of this Agreement, or otherwise) (a “Payment”) is subject to the excise tax imposed by
Section 4999 of the Code or any interest or penalties are incurred by Executive with respect to such excise tax (such excise tax, together with any such interest and penalties, hereinafter collectively referred to as the “Excise
Tax”), Executive shall be entitled to receive an additional payment (a “Gross-Up Payment”) in an amount such that after payment by Executive of all taxes (including any interest or penalties imposed with respect to such taxes),
including, without limitation, any 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. 
 Paragraph 2. All determinations required to be made under this Exhibit V,
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 Exhibit V, shall be paid by the Company to Executive (or to the appropriate taxing authority on Executive’s behalf) when due. If the Accounting Firm determines that no Excise Tax is payable by Executive, it shall so indicate to
Executive in writing. Any determination by the Accounting Firm shall be binding upon the Company and Executive (subject to Paragraph 3). As a result of the uncertainty in the application of Section 4999 of the Code, it is possible that the
amount of the Gross-Up Payment determined by the Accounting Firm to be due to (or on behalf of) Executive was lower than the amount actually due (“Underpayment”). In the event that the Company exhausts its remedies pursuant to Paragraph 3
of Exhibit V 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). 







 Paragraph 3. Executive shall notify the Company in writing of any claim by the Internal Revenue Service that, if
successful, would require the payment by the Company of any Gross-Up Payment. Such notification shall be given as soon as practicable but no later than ten (10) business days after Executive is informed in writing of such claim and shall
apprise the Company of the nature of such claim and the date on which such claim is requested to be paid. Executive shall not pay such claim prior to the expiration of the thirty (30) day period following the date on which it gives such notice
to the Company (or such shorter period ending on the date that any payment of taxes with respect to such claim is due). If the Company notifies Executive in writing prior to the expiration of such period that it desires to contest such claim,
Executive shall (i) give the Company any information reasonably requested by the Company relating to such claim, (ii) take such action in connection with contesting such claim as the Company shall reasonably request in writing from time to
time, including, without limitation, accepting legal representation with respect to such claim by an attorney reasonably selected by the Company, (iii) cooperate with the Company in good faith in order to effectively contest such claim and
(iv) permit the Company to participate in any proceedings relating to such claim; provided, however, that the Company shall bear and pay directly all costs and expenses (including additional interest and penalties) incurred in connection with
such contest and shall indemnify and hold Executive harmless, on an after-tax basis, for any Excise Tax or income tax (including interest and penalties with respect thereto) imposed as a result of such representation and payment of costs and
expenses. Without limitation on the foregoing provisions of this Paragraph 3, the Company shall control all proceedings taken in connection with such contest and, at its sole option, may pursue or forego any and all administrative appeals,
proceedings, hearings and conferences with the taxing authority in respect of such claim and may, at its sole option, either direct Executive to pay the tax claimed and sue for a refund or contest the claim in any permissible manner, and Executive
agrees to prosecute such contest to a determination before any administrative tribunal, in a court of initial jurisdiction and in one (1) or more appellate courts, as the Company shall determine; provided that if the Company directs Executive
to pay such claim and sue for a refund, the Company shall advance the amount of such payment to Executive, on an interest-free basis, and shall indemnify and hold Executive harmless, on an after-tax basis, from any Excise Tax or income tax
(including interest or penalties with respect thereto) imposed with respect to such advance or with respect to any imputed income with respect to such advance; provided, further, that if Executive is required to extend the statute of limitations to
enable the Company to contest such claim, Executive may limit this extension solely to such contested amount. The Company’s control of the contest shall be limited to issues with respect to which a Gross-Up Payment would be payable hereunder
and Executive shall be entitled to settle or contest, as the case may be, any other issue raised by the Internal Revenue Service or any other taxing authority. 
 Paragraph 4. If, after the receipt by Executive of an amount paid or advanced by the Company pursuant to this Exhibit V, Executive becomes entitled to receive any refund with respect to a Gross-Up Payment, Executive shall (subject to
the Company’s complying with the requirements of Paragraph 3 of this Exhibit V) promptly pay to the Company the amount of such refund received (together with any interest paid or credited thereon after taxes applicable thereto). If, after the
receipt by Executive of an amount advanced by the Company pursuant to Paragraph 3 of this Exhibit V, 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. 
 Paragraph 5. For the avoidance of doubt, all payments to or for the benefit of Executive provided for in this Exhibit V 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.
