THIS CONSULTING AGREEMENT (this “Agreement”), is dated January 1, 2012 (the

WHEREAS, the Company and Consultant previously entered into that certain
Consulting Agreement, dated as of May 16, 2008, and effective October 10, 2007
(the “Original Agreement”) to govern the terms and conditions of the engagement
of Consultant as non-executive Chairman (“Chairman”) of the Board of Directors
of the Company (the “Board”);
WHEREAS, the Original Agreement expired on October 10, 2009 and, in accordance
therewith, the Company and Consultant extended the Consultant's term as Chairman
in a Consulting Agreement dated as of February 18, 2010 and effective October
10, 2009 (the “Amended Consulting Agreement”);
WHEREAS, the Consultant and Company desire to amend the terms and conditions of

NOW, THEREFORE, in consideration of the mutual covenants and agreements set
forth in this Agreement, the Company and Consultant hereby agree as follows:
1.Appointment; Consulting Arrangement. The Company hereby confirms Consultant's
appointment as Chairman effective as of the Commencement Date, and Consultant
will, from time to time at the request of the Company and/or the Board upon
reasonable advance notice, provide external and internal leadership and
involvement in political and regulatory affairs of the Company and such other
duties and responsibilities as shall be agreed upon between Consultant and the
Company and/or the Board (collectively, the “Services”).

Nothing in this Agreement shall be deemed to affect Consultant's status as a

Formation, as amended.
2.Term; Termination. The term of Consultant's tenure as Chairman (the
“Consulting Term”) commenced as of Commencement Date and shall terminate on
December 31, 2015 (the “Initial Expiration Date”), unless extended by the mutual
agreement of the parties. If the parties agree to extend the Consulting Term

Consultant's compensation) may be revised by mutual agreement of the parties at
the time of such extension in light of the existing circumstances at the time.
The Company or Consultant may terminate this Agreement by giving thirty (30)
days prior written notice to the other party.

may

--------------------------------------------------------------------------------

(i) (A) continue to serve on the boards of directors of the entities listed on
and pursuant to Schedule 1 attached hereto and (B) serve on the boards of
directors of any investment fund or other pooled investment vehicle that is a
subsidiary or an affiliate of those entities listed on Schedule 1, including,
without limitation, any such subsidiary or affiliate that may be formed after

shall not be unreasonably withheld or delayed), serve on the board of directors
of other for-profit companies that do not compete with the Company, (iii) serve
on civic or charitable boards or committees, and (iv) manage personal
investments.
3.Compensation.

(a)Base Compensation. Consultant shall be paid in cash an annual advisory fee by
the Company equal to $2,500,000 per year (the “Base Fee”) in quarterly
installments of $625,000, payable on the last day of every third month during
the Consulting Term.
 
(b)Equity Arrangements.

(i)Stock Purchases. Once each fiscal year of the Consulting Term, during the
seven (7) day period beginning on the date the Company releases earnings for the
fourth quarter of the fiscal year, Consultant shall have the right, but not the
obligation, to purchase from the Company shares of Common Stock, no par value,
of the Company (“Common Stock”); provided, that, the aggregate fair market value
of the shares of Common Stock (determined as of the date(s) of purchase)
purchased by Consultant in any one fiscal year of the Company pursuant to this
Section 3(b)(i) shall not exceed $2,000,000. The purchase price per share of
Common Stock purchased pursuant to this Section 3(b)(i) shall be equal to the
fair market value (determined in accordance with the 2007 Stock Incentive Plan
for Key Employees of Energy Future Holdings Corp. and its Affiliates, as amended
from time to time (the “Plan”)) (“Fair Market Value”) on the date of purchase.
Any shares purchased by the Consultant pursuant to this Section 3(b)(i) shall be
promptly evidenced by book entry on the Company's stock record and no stock
certificates will be issued to Consultant.
 
(ii)Exchange of Options. No later than February 28, 2012, the Company shall
grant to Consultant an award (the “Exchange Option Award”) of an option to
purchase 600,000 shares of Common Stock. The Exchange Option Award shall be
fully vested when granted. The exercise price of the shares of Common Stock
covered by the option (the “Exercise Price”) shall be equal to the fair market
value, as determined by the Board, of one share of Common Stock as of the date
of grant, which, consistent with Treasury Regulation Section
1.409A-1(b)(5)(iv)(B), shall be the fair market value of such Common Stock as
determined by an independent appraisal, as of December 31, 2011, or, if use of
such value is determined by the Board not to be reasonable, then fair market
value shall be determined by the Board using an alternate reasonable valuation
method. The Exchange Option Award will be granted only if Consultant agrees to
the surrender and cancellation of the option award granted to Consultant in May
2008 and fully vested in October 2009.

(iii)New Options. No later than February 28, 2012, the Company shall grant to
Consultant an award (the “2012 Option Award”) of an option to purchase 4,400,000
shares of Common Stock. The Exercise Price shall be equal to the fair market
value, as determined by the Board, of one share of Common Stock as of the date
of grant, which, consistent with Treasury Regulation Section
1.409A-1(b)(5)(iv)(B), shall be the fair market value of such Common Stock as
determined by an independent appraisal, as of December 31, 2011, or, if use of
such value is determined by the Board not to be reasonable, then fair market
value shall be determined by the Board using an alternate reasonable valuation
method. Subject to the Consultant's continued service with the Company, the

--------------------------------------------------------------------------------

2012 Option Award shall become vested and exercisable in equal annual
installments, beginning on December 31, 2012 and each December 31 thereafter,
ending December 31, 2015.
  
(iv)Governing Documents. The rights and obligations of Consultant relating to
the Common Stock purchased directly by Consultant from the Company pursuant to
Section 3(b)(i) hereof shall be governed by the terms and conditions of a Stock
Purchase Agreement, a Stockholder Agreement, and a Sale Participation Agreement,
to be entered into between Consultant and the Company (collectively, the “Equity
Documents”). The rights and obligations of Consultant relating to the Common
Stock issued pursuant to Sections 3(b)(ii) and 3(b)(iii) shall be governed by
the terms and conditions of a Stock Option Agreement to be entered into between
Consultant and the Company, the Sale Participation Agreement, dated May 16,
2008, and the Stockholder Agreement, dated May 16, 2008.

(c)If Consultant Terminates the Agreement without Good Reason or if the Company
Terminates the Agreement for Cause. If Consultant terminates the Agreement for
any reason other than for Good Reason or the Company terminates the Agreement
for Cause (both as defined herein), (i) Consultant shall forfeit any right to
compensation not yet granted or paid under Section 3(a) or 3(b), except a
pro-rated portion of the Base Fee not yet paid by the Company but earned by
Consultant prior to the termination of the Agreement (calculated as set forth
below), which shall be paid in a single lump sum within thirty (30) days
following the termination of the Agreement; and (ii) Consultant shall be
entitled, subject to the requirements of Section 4(a), to receive reimbursement
for any reasonable expenses incurred in connection with the performance of
Services prior to the end of the Consulting Term. The calculation of any Base
Fee to be paid to Consultant under this Section 3(c) following termination of
the Agreement shall be determined by multiplying $625,000 by a fraction, the
numerator of which is the number of days commencing on the first day of the
quarter in which such termination occurred and ending on the date of termination
and the denominator of which is the number of days in the quarter.

(d)If Consultant Terminates the Agreement for Good Reason or the Company
Terminates the Agreement Without Cause. If Consultant terminates the Agreement
for Good Reason or the Company terminates the Agreement for any reason other
than Cause (as defined below), the Company shall provide to Consultant the
following: (i) any unpaid Base Fee (whether or not earned at the time of
termination) that would have been paid to Consultant if the Services had
continued until the end of the Consulting Term, which Base Fee shall be paid in
a single lump sum within thirty (30) days following the termination of the
Agreement, and (ii) subject to the requirements of Section 4(a), reimbursement
for any reasonable expenses incurred in connection with the performance of
Services prior to the end of the Term.

(e)Definitions. For purposes of this Agreement, the terms specified below shall
be given the following meanings:

(i)“Cause” shall be defined as: (A) Consultant's continued failure to
substantially perform the Services which continues beyond ten (10) days
following the date on which a written demand for substantial performance is
delivered to Consultant by the Company (the “Cure Period”); (B) if, in
performing Services for Company, Consultant engages in conduct that constitutes
(1) a material breach of his fiduciary duty to the Company or its shareholders
(including, without limitation, a material breach of the restrictive covenants
under this Agreement, which breach is not cured, if curable, during the Cure
Period after written notice from the Company) or (2) gross neglect or
(3) misconduct resulting in material economic harm to the Company, or (C) upon
the conviction of the Consultant for, or the plea of guilty or nolo contendere
by Consultant to, any crime involving moral turpitude and/or any felony.

--------------------------------------------------------------------------------

(ii)“Good Reason” shall mean, provided that Consultant has not previously given
the Company his written consent, (A) a reduction in Consultant's Base Fee or (B)
any material breach of this Agreement; provided, however, that any isolated,
insubstantial or inadvertent failure by the Company that is not in bad faith and
is cured within ten (10) business days after Consultant gives the Company
written notice of any such event set forth above, shall not constitute Good
Reason.

4.Expenses and Administrative Support.

(a)Reimbursement of Reasonable and Customary Business Expenses. In addition to
the compensation payable to Consultant pursuant to Section 3 hereof, Consultant
is authorized to incur reasonable and customary business expenses on the
Company's behalf in connection with the performance of Services hereunder,
including, without limitation, expenditures for business travel, lodgings, meals
and entertainment expenses (“Business Expenses”). The Company shall, subject to
the requirements of this Section 4(a), reimburse Consultant for all Business
Expenses upon presentation by Consultant, from time to time, of appropriately
itemized accounts of such expenditures. Consultant shall provide such itemized
accounts within sixty (60) days after the expense is incurred and the Company
shall reimburse Consultant within fifteen (15) days after receipt of such
account. Expenses shall be reimbursed as soon as practicable following the
Company's receipt of such accounts.

(b)Secondment of Personnel. Consultant shall be provided at the expense of the
Company with support from personnel of his choosing in the following roles, in
each case at the sole expense of the Company: 1) a Chief of Staff to be based in
either Dallas or Midland, Texas with an annual salary not to exceed $200,000; 2)
an executive assistant based in Dallas, Texas; and 3) an executive assistant
based in Midland, Texas.

(c)Expenses Associated with Midland Office. The Company agrees to pay Consultant
a flat fee of $100,000 per year to offset expenses associated with maintaining
Consultant's office in Midland, Texas. Such payments shall be made in quarterly
installments and at the same time as Consultant's Base Fee.
 
5.Status; Taxes.

(a)Status of Consultant. It is the intention of the parties hereto that, in
performing the Services, Consultant shall act as and be deemed in all respects
to be an independent contractor, and not for any purpose as an employee or agent
of the Company except on authority specifically so delegated to Consultant to
act as agent, and he shall not represent to the contrary to any person.
Consultant shall only consult, render advice and perform such tasks as
Consultant determines are necessary to provide the Services. Although the
Company may specify the tasks to be performed by Consultant and may control and
direct him in that regard, the Company shall not control or direct Consultant as
to the details or means by which such tasks are accomplished.

(b)Taxes. It is intended that the fees paid hereunder shall constitute income to
Consultant. Subject to the following provisions of this Section 5(b), Consultant
shall have full responsibility and the Company shall have no responsibility for
satisfying any liability for any federal, state or local income or other taxes
required by law to be paid with respect to the fees paid hereunder.

(c)Benefits. Consultant shall not be entitled to participate in any employee
benefit plans or other programs in which participation is restricted to
employees of the Company.

--------------------------------------------------------------------------------

6.Nondisclosure of Confidential Information and Non-Disparagement.

(a)Non-Disclosure of Confidential Information. Consultant shall not, without the
prior written consent of the Company, use, divulge, disclose or make accessible
to any other person, firm, partnership, corporation or other entity any
Confidential Information pertaining to the business of the Company, its parent
or any of its subsidiaries (each, an “Affiliate”), except (i) while providing
Services to the Company, in the business of and for the benefit of the Company,
or (ii) as required by law, provided, however, that if Consultant receives a
subpoena to produce any Confidential Information, Consultant will notify the
Company promptly so that the Company can seek a protective order, if desired.
For purposes of this Section 6, “Confidential Information” shall mean
information: (A) disclosed to or known by Consultant as a consequence of or
through his engagement with the Company or any Affiliate; (B) not publicly
available or not generally known outside the Company or any Affiliate; and
(C) that relates to the business and/or development of the Company or any
Affiliate. Any information that does not meet each of the criteria listed above
(in subsections (A) - (C)), other than by Consultant's breach of the terms
hereof, 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; 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
Consultant conceived or developed during his engagement with the Company or an
Affiliate or learned from other employees or contractors of the Company or an
Affiliate that meets the definition of Confidential Information shall be treated
as such. Consultant acknowledges that the Confidential Information of the
Company is valuable, special and unique to its business and is information on
which such business depends, is proprietary to the Company, and that the Company
wishes to protect such Confidential Information by keeping it secret and
confidential for the sole use and benefit of the Company. Consultant will take
all commercially reasonable steps necessary and reasonably requested by the
management of the Company, to ensure that all such Confidential Information is
kept secret and confidential for the sole use and benefit of the Company.

(b)Non-Disparagement.

(i)Consultant agrees not to defame, or make any false or disparaging statements
about the Company and/or its Affiliates, or any of their respective products,
services, finances, financial condition, capabilities or other aspect of or any
of their respective businesses, in any medium to any person or entity; or
otherwise, to take any action that primarily is designed to have the effect of
discouraging any employee, lessor, licensor, customer, supplier, or other
business associate of the Company from maintaining its business relationships
with the Company and/or its Affiliates (any

--------------------------------------------------------------------------------

such statement or act a “Prohibited Statement” or “Prohibited Action”).
Consultant shall be permitted to issue press releases, make statements to the
press, give guidance to the market or make statements to regulators,
governmental agencies, legislators or other governmental officials; or otherwise
to take such actions necessary in connection with Consultant's duties and
responsibilities under this Agreement, without such statements or actions being
considered a Prohibited Statement or Prohibited Action under this Agreement.

(ii)The Company hereby agrees that Company and its officers shall not defame, or
make any disparaging statements in any medium to any person or entity about
Consultant.

(iii)Notwithstanding any provision of this Section 6(b) to the contrary,
(A) both Consultant and the Company (including the Board and its executive
officers) may (1) confer in confidence with their legal representatives and make
truthful statements as required by law and (2) make private statements to any
officer, director or employee of the Company or any of its affiliates; and
(B) nothing herein shall prevent any person from (1) responding publicly to
incorrect, disparaging or derogatory public statements to the extent reasonably
necessary to correct or refute such public statement or (2) making any truthful
statement to the extent (x) necessary with respect to any litigation,
arbitration or mediation involving this Agreement (or any Exhibit hereto) or any
other agreement among or between any party hereto or (y) required by law or by
any court, arbitrator, mediator or administrative or legislative body (including
any committee thereof) with actual or apparent jurisdiction to order such person
to disclose or make accessible such information.

(iv)By signing this Agreement, Consultant agrees and acknowledges that
Consultant is making, after the opportunity to confer with counsel, a knowing,
voluntary and intelligent waiver of rights Consultant may have to make
disparaging comments regarding the Company and/or its affiliates, including
rights under the First Amendment to the United States Constitution and any other
applicable federal and state constitutional rights.

(c)The non-disclosure and non-disparagement obligations contained in this
Section 6 shall continue in full force and effect after the conclusion of
Consultant's engagement with the Company and shall survive the expiration,
termination, or cancellation of this Agreement, in each case in accordance with
their respective terms, regardless of the reason for such termination or
restriction. Consultant's obligations with respect to any specific Confidential
Information shall cease only when that specific portion of the Confidential
Information becomes publicly known, other than as a result of disclosure by
Consultant, in its entirety, without combining portions of such Confidential
Information with other Confidential Information obtained separately.

7.Indemnification. The Company shall, to the fullest extent permitted by law,
indemnify and hold Consultant harmless if Consultant is, or is threatened to be,
made a party to or involved in any other capacity in any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (including any action by or in the right of the Company or its
affiliates), by reason of any actions or omissions or alleged acts or omissions
arising out of Consultant's activities either on behalf of the Company or its
affiliates or in what Consultant reasonably believed to be in furtherance of the
interests of any of the above or arising out of or in connection with any of the
above, if such activities were performed in good faith either on behalf of the
Company or its affiliates and in a manner reasonably believed by Consultant to
be within the scope of the authority conferred to Consultant or conferred by
law, against losses, damages or expenses for which Consultant has not otherwise
been reimbursed (including attorneys' fees, judgments, fines and amounts paid in
settlement) and which were actually incurred by Consultant in connection with
such action, suit or proceeding. In addition, Consultant shall be covered, in

--------------------------------------------------------------------------------

respect of Consultant's activities as a director of the Company, by the
Company's Directors and Officers liability policy or other comparable policies
obtained by the Company's successors, to the fullest extent permitted by such
policies.

unenforceability shall not affect the remaining provisions hereof which shall
remain in full force and effect.
