 EFH 
 SECOND SUPPLEMENTAL RETIREMENT PLAN 
 (As amended and restated effective as of October     , 2007) 

ARTICLE ONE  
 Purposes of the
Plan 
 1.1 The EFH Second Supplemental Retirement Plan (“Plan”) is a restatement and amendment of the TXU Supplemental
Retirement Plan (the “First Plan”) which was initially established, effective January 1, 1983, was amended and restated effective as of January 1, 1995, August 11, 1998, May 12, 2000, August 17,
2001, January 1, 2005, and January 1, 2007. The Plan is renamed and restated effective as of October 10, 2007, in order to recognize the change in the Company’s name from TXU Corp. to Energy Future Holdings Corp. As amended
and restated, the Plan is intended to satisfy the requirements of Code section 409A. The principal purpose of the Plan is to provide benefits, not otherwise provided by the First Plan, for Participants in excess of the limitations on contributions
and benefits imposed by relevant provisions of the Internal Revenue Code of 1986, as amended (the “Code”), on qualified defined benefit plans. 
 1.2 The Plan is established for the benefit of Participants as an unfunded compensation arrangement; provided, however, Supplemental Retirement Benefits for Eligible Participants shall be provided, in whole or
in part, under the Trust Agreement for Participants who are eligible to receive Supplemental Retirement Benefits under the Trust Agreement, and shall be provided under the Second Trust Agreement for all other Participants and for Eligible
Participants, to the extent such Supplemental Retirement Benefits are not payable under the Trust Agreement. Any Supplemental Retirement Benefit not paid under the Trust Agreement or the Second Trust Agreement shall be paid by the Participating
Employer under the provisions of the Plan. 
  

 1 

 1.3 The Plan does not give Participants any rights not expressly granted them in the Plan.

 ARTICLE TWO 
 Definitions

 The following definitions apply to the Plan unless the context clearly indicates otherwise: 
 2.1 “Adjusted Retirement Benefit” shall mean the Retirement Income Allowance which would have been payable under the provisions of
Section 7 of the Retirement Plan without regard to Section 8 of the Retirement Plan and without excluding from Earnings: (i) amounts awarded under the Company’s Executive Annual Incentive Plan (“Executive AIP”) (but
only with respect to Participants who are employed by Oncor Electric Delivery Company LLC, and other Participants who, as of October 1, 2008, were participating in the Executive AIP), or amounts deferred under nonqualified executive
compensation plans and arrangements adopted from time to time by Participating Employers; and (ii) amounts in excess of the dollar maximum imposed on Earnings, as defined in the Retirement Plan. Adjusted Retirement Benefit shall also mean and
include special retirement compensation not payable under the Retirement Plan to which a Participating Employer is contractually committed to pay to a Participant pursuant to an individually negotiated agreement between the Participating Employer
and the Participant. For purposes of this Plan, such special retirement compensation shall be referred to as “Special Contractual Retirement Compensation.” 
 2.2 “Board of Directors” shall mean the Board of Directors of TXU Corp. 
 2.3
“Affiliated Entity” shall mean any entity, more than 50% of the equity interest or profit interest of which is owned, directly or indirectly by the Company; any company which is 

  

 2 

 
in a controlled group of corporations (within the meaning of Code section 414(b)) that includes any such Affiliated Entity; any entity that is under common
control (within the meaning of Code section 414(c)) that includes any such Affiliated Entity; and any entity that is within an affiliated service group (determined in accordance with Code section 414(m)) that includes any such Affiliated Entity.

 2.4 “Change in Control” shall mean means the occurrence of any one or more of the following events: 
 (a) individuals who, on the effective date hereof, constitute the Board of Directors (the “Board”) of the Company (the “Incumbent
Directors”) cease for any reason to constitute at least a majority of the Board, provided that any person becoming a director subsequent to the effective date whose election or nomination for election was approved by a vote of at least
two-thirds of the Incumbent Directors then on the Board (either by a specific vote or by approval of the proxy statement of the Company in which such person is named as a nominee for director, without written objection to such nomination) shall be
an Incumbent Director; provided, however, that no individual initially elected or nominated as a director of the Company as a result of an actual or threatened election contest with respect to directors or as a result of any other actual or
threatened solicitation of proxies or consents by or on behalf of any person other than the Board shall be deemed to be an Incumbent Director; 
 (b) any “person” (as such term is defined in Section 3(a)(9) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and as used in Sections 13(d)(3) and 14(d)(2) of the Exchange Act) is or
becomes a “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing 25% or more of the combined voting power of the Company’s then outstanding
securities eligible to 

  

 3 

 
vote for the election of the Board (the “Company Voting Securities”); provided, however, that the event described in this paragraph (b) shall
not be deemed to be a Change in Control by virtue of any of the following acquisitions: (1) by the Company or any entity a majority of the voting securities or other voting interests of which are owned, directly or indirectly, by the
Company (“Subsidiary”), (2) by any employee benefit plan (or related trust) sponsored or maintained by the Company or any Subsidiary, (3) by any underwriter temporarily holding securities pursuant to an offering of such
securities, (4) pursuant to a Non-Qualifying Transaction (as defined in paragraph (c) below), (5) with respect to any Eligible Executive, pursuant to any acquisition by such Eligible Executive or any group of persons including such
Eligible Executive (or any entity controlled by such Eligible Executive or controlled by any group of persons including such Eligible Executive); or (6) a transaction (other than one described in paragraph (c) below) in which Company
Voting Securities are acquired from the Company, if a majority of the Incumbent Directors approve a resolution providing expressly that the acquisition pursuant to this clause (6) does not constitute a Change in Control under this
paragraph (b); 
 (c) the consummation of a merger, consolidation, statutory share exchange or similar form of corporate transaction
involving the Company or any of its Subsidiaries that requires the approval of the Company’s shareholders other than approval required solely by Article XI of the Company’s articles of incorporation, whether for such transaction or the
issuance of securities in the transaction (a “Business Combination”), unless immediately following such Business Combination: (1) more than 50% of the total voting power of (x) the corporation or other entity resulting from such
Business Combination (the “Surviving Corporation”), or (y) if applicable, the ultimate parent corporation or other entity that, directly or indirectly, has beneficial ownership of at least 95% of the voting securities eligible to
elect directors (or persons 

  

 4 

 
performing similar functions) of the Surviving Corporation (the “Parent Corporation”), is represented by Company Voting Securities that were
outstanding immediately prior to such Business Combination (or, if applicable, is represented by voting securities into which such Company Voting Securities were converted or for which such Company Voting Securities were exchanged pursuant to such
Business Combination), and such voting power of the Parent Corporation (or, if there is no Parent Corporation, the Surviving Corporation) among the holders thereof is held in substantially the same proportion as the voting power of such Company
Voting Securities held by the holders thereof immediately prior to the Business Combination, (2) no person (other than any employee benefit plan (or related trust) sponsored or maintained by the Surviving Corporation or the Parent Corporation,
as the case may be, or any Subsidiary thereof), is or becomes the beneficial owner, directly or indirectly, of 25% or more of the total voting power of the outstanding voting securities eligible to elect directors (or persons performing similar
functions) of the Parent Corporation (or, if there is no Parent Corporation, the Surviving Corporation) and (3) at least a majority of the members of the board of directors (or similar governing body) of the Parent Corporation (or, if there is
no Parent Corporation, the Surviving Corporation) following the consummation of the Business Combination were Incumbent Directors at the time of the Board’s approval of the execution of the initial agreement providing for such Business
Combination or, if any director was elected after such time but prior to the consummation of such Business Combination, such director was elected to fill a vacancy on the Board created in the ordinary course and qualifies as an Incumbent Director
(any Business Combination which satisfies all of the criteria specified in (1), (2) and (3) above shall be deemed to be a “Non-Qualifying Transaction”); or 
  

 5 

 (d) the consummation of a complete liquidation or dissolution of the Company required to be approved by
the Company’s shareholders or a sale of all or substantially all of the assets of the Company and its Subsidiaries, considered as a whole. 
 Notwithstanding the foregoing, a Change in Control of the Company shall not be deemed to occur solely because any person acquires beneficial ownership of more than 25% of the Company Voting Securities as a result of the acquisition of
Company Voting Securities by the Company which reduces the number of Company Voting Securities outstanding; provided, that if after such acquisition by the Company such person becomes the beneficial owner of additional Company Voting Securities that
increases the percentage of outstanding Company Voting Securities beneficially owned by such person, a Change in Control of the Company shall then occur.

 ARTICLE FOUR  
 Benefits 
 4.1 A Participant shall be entitled to receive a Supplemental Retirement Benefit, pursuant to the provisions of the Plan and/or the First Plan;
provided, however, Benefits payable to Eligible Participants under the Trust Agreement or the Second Trust Agreement shall be subject to additional provisions set forth in the Trust Agreement and/or the Second Trust

 (i) With respect to a Participant entitled to a benefit under the Traditional
Retirement Plan Formula of the Retirement Plan, in the form of a single life annuity or any other actuarially equivalent life annuity form available under the Retirement Plan (which shall specifically exclude payment in a lump sum or any Social
Security leveling option), commencing upon the later of (A) the first day of the month following such Participant’s Separation from Service, or (B) the earliest date at which such Participant would be eligible to commence benefits

defined therein) if such Participant had remained in continuous employment and not experienced a Separation from Service. 
  

 9 

 4.3 Special Contractual Retirement Compensation shall be paid at such time and in such form as
provided in the underlying agreement or as elected by the Participant pursuant to the terms thereof; provided, however that if the Plan Administrator determines that the terms of such agreement, or the circumstances of such election, do not meet the
requirements of Code section 409A or any applicable transition relief, such Special Contractual Retirement Compensation shall be paid pursuant to the applicable provisions of Section 4.2(b)(i) or 4.2(b)(ii) above, or, if said sections do not

death of the Participant, or (b) if, at the time of such Participant’s Separation from Service, no stock of either the Company or the Participant’s employer is publicly traded on an established securities market or otherwise.

 4.6 Any Benefit payable under the Plan shall constitute a general unsecured obligation of the Company, and shall be subject to the
claims of the Company’s creditors. 
  

 10 

 ARTICLE FIVE  
 Miscellaneous 
 5.1 The Board of Directors shall be vested with full power and authority to
amend the Plan or to terminate the Plan at any time; provided that no act of amendment or termination shall reduce any Benefit accrued to the date such act is adopted. Furthermore, if the Plan is terminated, amended, or frozen or any other action is
taken to limit future Benefit accruals under the Plan, or in the event of a Change in Control, each of the Participating Employers shall be obligated to take all action as may be provided for under the Trust Agreement, the Second Trust Agreement or
any other agreement affecting, in any way, the funding and/or securitization and the current or future payment of Benefits. 
 5.2 The
Plan Administrator shall have the same powers, duties and responsibilities with respect to the administration of the Plan as provided to the Plan of Administrator under the Retirement Plan for purposes of administering the terms thereof.
Furthermore, the Plan Administrator may appoint one or more persons to assist in carrying out the day-to-day operation of the Plan, the Trust Agreement and/or the Second Trust Agreement. The powers, duties and responsibilities of the Plan
Administrator shall include specifically, but not by way of limitation, the authority to carry out the policy of the Company that applicable remuneration for a taxable year beginning after December 31, 1993, with respect to an Eligible
Participant, shall not exceed the level of deductibility provided for in Section 162(m) of the Internal Revenue Code or any successor provision. Notwithstanding any other provision of this Plan, in the event of a Change in Control, the
Independent Committee shall have the powers, duties and responsibilities provided for in the Second Trust Agreement. 
 5.3
Notwithstanding Section 5.1 or any other provision of the Plan or the Trust to the contrary, the Plan Administrator may authorize the Trustee to make the following payments even 

  

 11 

 
if they would otherwise not be permitted by the Trust, and a Participating Employer may refrain from making any contributions or payments otherwise required
or permitted to be made by the Plan or the Trust, to the extent necessary to satisfy the following requirements. 
 (a) No
amount shall be set aside or reserved directly or indirectly (under the Trust or otherwise), during any restricted period (as defined in Section 409A(b)(3)(B) of the Code) for the purpose of paying a Benefit under the Plan to any Eligible
Participant who is an applicable covered employee (as defined in Section 409A(b)(3)(D) of the Code). It is understood that a restricted period will generally occur in a Plan Year if any single-employer defined benefit plan (an “Applicable
Plan”) maintained by the Company or any company that is in a controlled group that includes the Company (within the meaning of Sections 414(b) and (c) of the Code and guidance issued by the Internal Revenue Service) is “at risk”
within the meaning of Section 430(i) of the Code for the preceding Plan Year. “Applicable covered employee” generally includes any Participant who is, with respect to the Company or any entity under common control with the Company,
described in section 162(m)(3) of the Code or subject to the requirements of Section 16(a) of the Securities Exchange Act of 1934. All such persons are referred to herein as “Covered Employees.” 
 (b) The Plan Administrator shall monitor the funding status of each Applicable Plan and will determine whether a restricted period exists
with respect to any such plan. If the Plan Administrator determines that a restricted period exists for a Plan Year, it shall determine whether any amount, including earnings, has been set aside or reserved during that period for the purpose of
paying a Benefit to any Covered Employee or would be set aside but for the action of the Plan Administrator. The Plan 

  

 12 

 
Administrator may request the Trustee to pay such amount to the Company or to any other person designated by the Plan Administrator or to otherwise segregate
such amount from the assets of the Trust. The foregoing shall not apply, however, to the extent that the Company elects to treat the amount set aside or reserved as a transfer of property for tax purposes and taxable to the Covered Employee
accordingly. 
 (c) Subject to any guidance issued by the Internal Revenue Service, the Plan Administrator may use any method
it deems appropriate to calculate the amount set aside or reserved for any Covered Employee during a restricted period. The determination made by the Plan Administrator shall be binding on the Trustee and each Covered Employee and any person
claiming any interest in or payment from the Trust related to such Covered Employee. The Plan Administrator may also utilize any program approved by the Internal Revenue Service to correct any amount that was improperly set aside under the Trust,
and may adopt such rules and procedures as it deems necessary to comply with Section 409A(b)(3) of the Code. 
 (d) The
Plan Administrator shall maintain a record of any amount transferred from the Trust pursuant to paragraph (b), or that a Participating Employer does not contribute to the Trust. Such amount shall be credited with interest or earnings based on what
would have been allocable to such amounts if they had been held in the Trust. Such amount shall be paid to the Trust as soon as possible after the Plan Administrator determines that no Applicable Plan remains in a restricted period. If any payment
from the Trust to a Covered Employee or the Covered Employee’s beneficiary has been reduced or withheld as a result of the restrictions of this Section, such amount shall be paid to such employee in a lump sum as soon as possible after the
amount contemplated in the foregoing sentence is paid to the Trustee. The Company may also make such payments directly. 
  

 13 

 (e) The purpose of this Section is to comply with the restrictions of
Section 409A(b)(3) of the Code and shall be interpreted accordingly. This provision is intended to impose only those restrictions that are required by that Section and only on the persons covered by the Section. The Plan Administrator shall
interpret and apply this Section accordingly. 
 5.4 Any Participating Employer, as defined herein, may participate under this Plan
upon approval of the Board of Directors and approval of the board of directors of such Participating Employer. Any Participating Employer may, by action of its board of directors, withdraw from participation in the Plan upon thirty days prior notice
to the Company. 
 5.5 The Plan is intended to satisfy the requirements of Code section 409A and the regulations adopted thereunder,
and shall be construed to that end. Except as otherwise preempted by Federal law, the Plan shall be construed under the laws of Texas. 
 Executed on December 15, 2008, to be effective as of October 10, 2007.

 This AMENDED AND RESTATED 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 Parties previously entered into an employment

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

any sign on bonus received within one year before such termination or resignation. 
 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. On or after the Effective Date, the Company shall grant Executive: (i) an option to purchase 2,500,000 shares of Company common stock

executives of the Company, to the extent consistent with applicable law and the terms of the applicable plans and standard perquisites. 
 c.
During the Employment Term, Executive shall be entitled to fringe benefits consistent with the practices of the Company. 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

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. 
  

 4 

 b. Disability or Death. 
 (i) The Employment Term and Executive’s employment hereunder shall terminate upon Executive’s death and may be terminated by the Company if
Executive has a Disability as hereinafter defined. Upon termination of Executive’s employment hereunder for either Disability or death, Executive or Executive’s estate (as the case may be) shall be entitled to receive: 
 (A) the Accrued Rights; and 
 (B) a
pro-rata portion of the Annual Bonus Target, if any, that Executive would have been entitled to receive pursuant to Section 4 hereof for the fiscal year of termination, multiplied by a fraction, the numerator of which is the number of days
during which Executive was employed by the Company in the fiscal year of Executive’s termination, and the denominator of which is 365 (the “Pro-Rata Bonus”), with such Pro-Rata Bonus payable to Executive pursuant to Section 4 as
if Executive’s employment had not terminated. 
 Following Executive’s termination of employment due to death or Disability, except as set forth in
this Section 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 

  

 5 

 
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 
 (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 

  

 6 

 
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 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 

  

 7 

 
pursuant to this Section 8(e)(i)(C) during a period of time during which, in the absence of the 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); 
  

 8 

 (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
the date that is six (6) months following Executive’s termination of employment with the Company (or the earliest date as is permitted under Section 409A of the Code), provided that amounts which do not exceed the limits set forth in
Section 402(g)(1)(B) of the Code in the year of such termination shall be payable immediately upon termination. If any payments or benefits are deferred due to such requirements, such amounts will be paid in a lump sum to Executive at the end
of such six (6) month period. The Company shall consult with Executive in good faith regarding the implementation of the provisions of this Section 10(g). 
 h. Indemnity. The Company, Texas Energy Future Holdings Limited Partnership and Texas Energy Future Merger Sub Corp. shall indemnify and hold Executive harmless for all acts and omissions occurring during his
employment or service as a member of the Board of the Company and of such other companies (as applicable), or both, to the maximum extent provided under each of the Company’s and such other companies’ charters, certificates of formation,
limited partnership agreements, by-laws and applicable law. During the Employment Term and for a term of six (6) years thereafter, the Company, or any successor to the Company, and such other companies, above, and their successors, shall
purchase and maintain, at their own expense, directors’ and officers’ liability insurance providing coverage for Executive in the same amount as for members of the Board. 
 i. Successors; Binding Agreement. This Agreement shall inure to the benefit of and be binding upon personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. In the event of Executive’s death before receiving all amounts and benefits due to him hereunder, such amounts shall be payable to Executive’s estate or as otherwise
provided under applicable benefit plans or arrangements. 
 j. Notice. For the purpose of this Agreement, notices and all other
communications provided for in the Agreement shall be in writing and shall be deemed to have been duly given when delivered by hand or overnight courier or three (3) days after it has been mailed by United States registered mail, return receipt

 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). 
  

 Exhibit V - 1 

 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 

  

 Exhibit V - 2 

 
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.
