You are entitled to receive all cash distributions made with respect to
Restricted Units registered in your name and are entitled to vote such
Restricted Units, unless and until the Restricted Units are forfeited. Such cash
distribution shall be made without interest no later than on the first day of
the month next following the month in which cash distributions are made to
Unitholders.

The number of Restricted Units that vest as of each date described above will be
rounded down to the nearest whole Restricted Unit, with any remaining Restricted
Units to vest with the final installment. Your employment with the Partnership,

order for the Award to become vested with respect to additional Units on such
date.

3.   EVENTS OCCURRING PRIOR TO REGULAR VESTING.

     (A)  DEATH OR DISABILITY. If your employment with the Employer terminates
          as a result of your death or a disability (within the meaning of
          Section 22(e)(3) of the Internal Revenue Code of 1986, as amended and
          in effect from time to time (the "Code")), the Restricted Units then
          held by you automatically will become fully vested upon such
          termination.

<PAGE>

     (B)  TERMINATION BY THE PARTNERSHIP OTHER THAN FOR CAUSE. If your
          employment is terminated by the Partnership for any reason other than
          "Cause," as determined by the Partnership, the Restricted Units then
          held by you automatically will become fully vested upon such
          termination.

     (C)  OTHER TERMINATIONS. Except as provided in Section 3 hereof, if you
          terminate from the Partnership for any reason other than as provided
          in Sections 3(a) and (b) above, all unvested Restricted Units then
          held by you automatically shall be forfeited without payment upon such
          termination.

     (D)  CHANGE OF CONTROL. All outstanding Restricted Units held by you
          automatically shall become fully vested upon a Change of Control.

For purposes of this Section 3, "employment with the Partnership" shall include
being an employee of or a director or consultant to the Partnership or an
Affiliate.

For purposes of this Section 3, "Cause" is defined as:

(1) an act by the Grantee of willful misrepresentation, fraud or willful
dishonesty intended to result in substantial personal enrichment at the expense
of the Partnership or an Affiliate;

(2) the Grantee's willful misconduct with regard to the Partnership or an
Affiliate that is intended to have a material adverse impact on the Partnership
or an Affiliate;

Affiliate guidelines or policies or the Grantee's fiduciary duties which has or
is intended to have a material adverse impact on the Partnership or an
Affiliate;

(4) the Grantee's willful or reckless behavior in the performance of his or her
duties which has a material adverse impact on the Partnership or an Affiliate;

(5) the Grantee's willful failure to perform his or her duties or to follow a
written direction of the Chairman or the board of directors of the Partnership;

(6) the Grantee's conviction of, or pleading nolo contendere or guilty to, a
felony; or

(7) any other willful material breach by the Grantee of his or her obligations
to the Partnership or an Affiliate that, if curable, is not cured within 20 days
of receipt of written notice from the Partnership or an Affiliate.

4.   UNIT CERTIFICATES. A certificate evidencing the Restricted Units may be
     issued in your name, pursuant to which you shall have all voting rights.
     The certificate shall bear the following legend:

                  The Units evidenced by this certificate have been issued
         pursuant to an agreement made as of ________, 200__, a copy of which is
         attached hereto and incorporated herein, between Legacy Reserves LP
         (the "Partnership") and the registered holder of the Units, and are
         subject to forfeiture

                                       2

<PAGE>

         to the Partnership under certain circumstances described in such
         agreement. The sale, assignment, pledge or other transfer of the Units
         evidenced by this certificate is prohibited under the terms and
         conditions of such agreement, and such Units may not be sold,
         assigned, pledged or otherwise transferred except as provided in such
         agreement.

The Partnership may cause the certificate to be delivered upon issuance to the
Secretary of the Company as a depository for safekeeping until the forfeiture
occurs or the restrictions lapse pursuant to the terms of this Agreement. Upon
request of the Partnership, you shall deliver to the Partnership a unit power,
endorsed in blank, relating to the Restricted Units then subject to the
restrictions. Upon the lapse of the restrictions without forfeiture, the
Partnership shall cause a certificate or certificates to be issued without
legend in your name in exchange for the certificate evidencing the Restricted
Units.

5.   LIMITATIONS UPON TRANSFER. All rights under this Agreement shall belong to
     you alone and may not be transferred, assigned, pledged, or hypothecated by
     you in any way (whether by operation of law or otherwise), other than by
     will or the laws of descent and distribution and shall not be subject to
     execution, attachment, or similar process. Upon any attempt by you to
     transfer, assign, pledge, hypothecate, or otherwise dispose of such rights
     contrary to the provisions in this Agreement or the Plan, or upon the levy
     of any attachment or similar process upon such rights, such rights shall
     immediately become null and void.

6.   RESTRICTIONS. By accepting this grant, you agree that any Units which you
     may acquire upon vesting of this award will not be sold or otherwise
     disposed of in any manner which would constitute a violation of any
     applicable federal or state securities laws. You also agree that (i) the
     certificates representing the Units acquired under this award may bear such
     legend or legends as the Committee deems appropriate in order to assure
     compliance with applicable securities laws, (ii) the Company may refuse to
     register the transfer of the Units acquired under this award on the
     transfer records of the Partnership if such proposed transfer would in the
     opinion of counsel satisfactory to the Partnership constitute a violation
     of any applicable securities law, and (iii) the Partnership may give
     related instructions to its transfer agent, if any, to stop registration of
     the transfer of the Units to be acquired under this award.

7.   WITHHOLDING OF TAX. To the extent that the grant or vesting of a Restricted
     Unit results in the receipt of compensation by you with respect to which
     the Partnership or an Affiliate has a tax withholding obligation pursuant
     to applicable law, unless other arrangements have been made by you that are
     acceptable to the Partnership or such Affiliate, you shall deliver to the
     Partnership or the Affiliate such amount of money as the Partnership or the
     Affiliate may require to meet its withholding obligations under such
     applicable law. No issuance of an unrestricted Unit shall be made pursuant
     to this Agreement until you have paid or made arrangements approved by the
     Partnership or the Affiliate to satisfy in full the applicable tax
     withholding requirements of the Partnership or Affiliate with respect to
     such event.

                                       3

     under Section 83(b) of the Code, to include an amount in income in respect
     of the Award of Restricted Units in accordance with the requirements of

9.   BINDING EFFECT. This Agreement shall be binding upon and inure to the
     benefit of any successor or successors of the Partnership and upon any
     person lawfully claiming under you.

     parties with regard to the subject matter hereof, and contains all the
     covenants, promises, representations, warranties and agreements between the
     parties with respect to the Restricted Units granted hereby. Without
     limiting the scope of the preceding sentence, all prior understandings and

     hereof are hereby null and void and of no further force and effect. Any
     modification of this Agreement shall be effective only if it is in writing
     and signed by both you and an authorized officer of the Company.

                              EMPLOYMENT AGREEMENT

     The parties to this Employment Agreement (this "Agreement") are LEGACY
RESERVES SERVICES, INC., a Texas corporation (the "Employer") and CARY D. BROWN
(the "Employee"). The parties desire to provide for the employment of the
Employee as Chief Executive Officer of LEGACY RESERVES GP, LLC, a Delaware
limited liability company (the "Company") on the terms set forth herein
effective as of the date of completion of a private placement of equity
securities ("Units") of LEGACY RESERVES LP, a Delaware limited partnership
("Legacy"). Legacy is joining in this agreement for the limited purposes of
reflecting its agreement to the matters set forth herein as to it, but such
joinder is not intended to make Legacy the employer of the Employee for any
purpose. The date this Agreement becomes effective is herein referred to as the
"Effective Date".

1. POSITION AND DUTIES

     1.1 Employment; Titles; Reporting. On the Effective Date, the Employer
agrees to employ the Employee and the Employee agrees to enter employment with
the Employer, upon the terms and subject to the conditions provided under this
Agreement. During the Employment Term (as defined in Section 2), the Employee
will serve as Chief Executive Officer of the Company. In such capacity, the
Employee will report to and otherwise will be subject to the direction and
control of the Board of Directors of the Company (including any committee
thereof, the "Board") and will have such duties, responsibilities and
authorities as may be assigned to him by the Board from time to time and
otherwise consistent with such position in a public company, comparable in size
to Legacy, which is engaged in natural gas and oil acquisition, development and
production (including, but not limited to, maintaining, to the extent
applicable, compliance with the Sarbanes-Oxley Act of 2002 and related
regulations and all other federal, state and local laws and regulations, as well
as all regulations and rules of any exchange or electronic trading system on
which Legacy's securities may be traded).

     1.2 Duties. During the Employment Term, the Employee will devote
substantially all of his full working time to the business and affairs of the
Employer, the Company and Legacy, will use his best efforts to promote the
Employer's, the Company's and Legacy's interests and will perform his duties and
responsibilities faithfully, diligently and to the best of his ability,
consistent with sound business practices. The Employee may be required by the
Board to provide services to, or otherwise serve as an officer or director of,
any direct or indirect subsidiary of the Employer, the Company or Legacy (the
Employer, the Company, Legacy and all such direct and indirect subsidiaries of
the Employer, the Company or Legacy being referred to herein as the "Related
Parties"), as applicable. The Employee will comply with the Employer's, the
Company's and Legacy's policies, codes and procedures, as they may be in effect
from time to time, applicable to executive officers of the Company and Legacy.
Nevertheless, the Employee may, with the prior approval of the Board in each
instance, engage in such other business and charitable activities that do not
violate Section 7, create a conflict of interest with the Employer, the Company
or Legacy or materially interfere with the performance of his obligations to the
Employer, the Company or Legacy under this Agreement. The activities in which
the Employee is engaged as of the Effective Date, all of which have been
approved by the Board, are listed on Exhibit A hereto.

     1.3 Place of Employment. The Employee will perform his duties under this
Agreement at the Company's offices in Midland, Texas, with the likelihood of
substantial business travel.

<PAGE>

2. TERM OF EMPLOYMENT. The term of the Employee's employment by the Employer
under this Agreement (the "Employment Term") will commence on the Effective Date
and will continue until employment is terminated by either party under Section
5. The date on which the Employee's employment ends is referred to in this
Agreement as the "Termination Date."

3. COMPENSATION.

     3.1 Base Salary. During the Employment Term, the Employee will be entitled
to receive a base salary ("Base Salary") at an annual rate of not less than
$200,000 for services rendered to the Employer, any of its affiliates and any of
its or their direct or indirect subsidiaries, payable in accordance with the
Employer's regular payroll practices. The Employee's Base Salary will be
reviewed annually by the Board and may be adjusted upward in the Board's sole
discretion.

     3.2 Annual Bonus Compensation. During the Employment Term, the Employee
will be entitled to receive incentive compensation in such amounts and at such
times as the Board may determine in its sole discretion to award to him under
any incentive compensation or other bonus plan or arrangement as may be
established by the Board from time to time (collectively, the "Employee Bonus
Plan"). Any additional incentive compensation payable under any Employee Bonus
Plan will be referred to in the aggregate in this Agreement as the Employee's
"Bonus."

     3.3 Long-Term Incentive Compensation. Awards of Unit options, Unit grants,
restricted Units and/or other forms of equity-based compensation to the Employee
on or after the Effective Date may be made from time to time during the
Employment Term by the Board in its sole discretion, whose decision will be
based upon performance and award guidelines for executive officers of the
Company and Legacy established periodically by the Board in its sole discretion.

4. EXPENSES AND OTHER BENEFITS.

     4.1 Reimbursement of Expenses. The Employee will be entitled to receive
prompt reimbursement for all reasonable expenses, including professional fees,
incurred by him during the Employment Term (in accordance with the policies and
practices presently followed by the Company or as may be established by the
Board from time to time for the Company's senior executive officers) in
performing services under this Agreement, provided that the Employee properly
accounts for such expenses in accordance with the Company's and Legacy's
policies as in effect from time to time.

     4.2 Vacation. Employee will be entitled to paid vacation time each year
during the Employment Term that will accrue in accordance with the Company's
policies and procedures now in force or as such policies and procedures may be
modified with respect to all senior executive officers of the Company.

     4.3 Other Employee Benefits. In addition to the foregoing, during the
Employment Term, the Employee will be entitled to participate in and to receive
benefits as a senior executive under all of the Company's and Legacy's employee
benefit plans, programs and arrangements available to senior executives, subject
to the eligibility criteria and other terms and conditions thereof, as such
plans, programs and arrangements may be duly amended, terminated, approved or
adopted by the Board from time to time.

5. TERMINATION OF EMPLOYMENT.

     5.1 Death. The Employee's employment under this Agreement will terminate
upon his death.

     5.2 Termination by the Employer.

          (a) Terminable at Will. The Employer may terminate the Employee's
     employment under this Agreement at any time with or without Cause (as
     defined below).

          (b) Definition of Cause. For purposes of this Agreement, the Employer
     will have "Cause" to terminate the Employee's employment under this
     Agreement by reason of any of the following: (i) the Employee's conviction
     of, or plea of nolo contendere to, any felony or to any crime or offense
     causing substantial harm to any of Legacy or its direct or indirect
     subsidiaries (whether or not for personal gain) or involving acts of theft,
     fraud, embezzlement, moral turpitude or similar conduct; (ii) the
     Employee's repeated intoxication by alcohol or drugs during the performance
     of his duties; (iii) malfeasance in the conduct of Employee's duties,
     including, but not limited to, (A) willful and intentional misuse or
     diversion of any of the Related Parties' funds, (B) embezzlement or (C)
     fraudulent or willful and material misrepresentations or concealments on
     any written reports submitted to any of the Related Parties; (iv) the
     Employee's material failure to perform the duties of the Employee's
     employment consistent with Employee's position, expressly including the
     provisions of this Agreement, or material failure to follow or comply with
     the reasonable and lawful written directives of the Board; (v) a material
     breach of this Agreement; or (vi) a material breach by the Employee of
     written policies of the Related Parties concerning employee discrimination
     or harassment.

          (c) Notice and Cure Opportunity in Certain Circumstances. The Employee
     may be afforded a reasonable opportunity to cure any act or omission that
     would otherwise constitute "Cause" hereunder according to the following
     terms: The Board will cause the Employer to give the Employee written
     notice stating with reasonable specificity the nature of the circumstances
     determined by the Board in good faith to constitute "Cause." If, in the
     good faith judgment of the Board, the alleged breach is reasonably
     susceptible to cure, the Employee will have fifteen (15) days from his
     receipt of such notice to effect the cure of such circumstances or such
     breach to the good faith satisfaction of the Board. The Board will state
     whether the Employee will have such an opportunity to cure in the initial
     notice of "Cause" referred to above. If, in the good faith judgment of the
     Board the alleged breach is not reasonably susceptible to cure, or such
     circumstances or breach have not been satisfactorily cured within such
     fifteen (15) day cure period, such breach will thereupon constitute "Cause"
     hereunder.

     5.3 Termination by the Employee.

          (a) Terminable at Will. The Employee may terminate his employment
     under this Agreement at any time with or without Good Reason (as defined
     below).

          (b) Notice and Cure Opportunity. If such termination is with Good
     Reason, the Employee will give the Employer written notice, which will
     identify with reasonable specificity the grounds for the Employee's
     resignation and provide the Employer with fifteen (15) days from the day
     such notice is given to cure the alleged grounds for resignation contained
     in the notice. A termination will not be for Good Reason if such

                                       -3-

<PAGE>

     notice is given by the Employee to the Employer more than thirty (30) days
     after the occurrence of the event that the Employee alleges is Good Reason
     for his termination hereunder.

          (c) Definition of Good Reason. For purposes of this Agreement, "Good
     Reason" will mean any of the following to which the Employee has not
     consented in writing: (a) a reduction in the Employee's Base Salary; (b) a
     relocation of the Employee's primary place of employment to a location more
     than 20 miles from Midland, Texas; or (c) any material reduction in the
     Employee's title, authority or responsibilities as Chief Executive Officer
     of the Company.

     5.4 Notice of Termination. Any termination of the Employee's employment by
the Employer or by the Employee during the Employment Term (other than
termination pursuant to Section 5.1) will be communicated by written Notice of
Termination to the other party hereto in accordance with Section 8.7. For
purposes of this Agreement, a "Notice of Termination" means a written notice
that (a) indicates the specific termination provision in this Agreement relied
upon, (b) to the extent applicable, sets forth in reasonable detail the facts
and circumstances claimed to provide a basis for termination of the Employee's
employment under the provision so indicated, and (c) if the Termination Date (as
defined herein) is other than the date of receipt of such notice, specifies the
Termination Date (which Termination Date will be not more than thirty (30) days
after the giving of such notice).

     5.5 Disability. If the Employer determines in good faith that the
Disability (as defined herein) of the Employee has occurred during the
Employment Term, it may, without breaching this Agreement, give to the Employee
written notice in accordance with Section 5.4 of its intention to terminate the
Employee's employment. In such event, the Employee's employment with the
Employer will terminate effective on the fifteenth (15th) day after receipt of
such notice by the Employee (the "Disability Effective Date"), provided that,
within the fifteen (15) days after such receipt, the Employee will not have
returned to full-time performance of the Employee's duties. "Disability" means
the determination by a physician selected by the Employer that the Employee has
been unable to perform substantially the Employee's usual and customary duties
under this Agreement for a period of at least one hundred twenty (120)
consecutive days or a non-consecutive period of one hundred eighty (180) days
during any twelve-month period as a result of incapacity due to mental or
physical illness or disease. At any time and from time to time, upon reasonable
request therefor by the Employer, the Employee will submit to reasonable medical
examination for the purpose of determining the existence, nature and extent of
any such disability.

6. COMPENSATION OF THE EMPLOYEE UPON TERMINATION.

     6.1 Death. If the Employee's employment under this Agreement is terminated
by reason of his death, the Employer will pay to the person or persons
designated by the Employee for that purpose in a notice filed with the Employer,
or, if no such person will have been so designated, to his estate, the amount of
(a) the Employee's accrued but unpaid Base Salary through the Termination Date
paid in a lump sum within thirty (30) days following the Termination Date, (b)
any accrued but unpaid Bonus, which Bonus will be payable at such time as the
bonuses of other executive officers of the Company are payable, (c) a pro rata
portion of any Bonus for the fiscal year in which the Termination Date occurs,
payable at such time as bonuses for the annual period are paid to other
executive officers of the Company, determined by multiplying the Employee's
target Bonus for such period by a fraction, the numerator of which is the number
of days from the first day of the fiscal year of the Company in which such

                                       -4-

<PAGE>

termination occurs through and including the Termination Date and the
denominator of which is 365 ("Pro Rata Bonus"), and (d) any other amounts that
may be reimbursable by the Employer to the Employee as expressly provided under
this Agreement paid in a lump sum within thirty (30) days following the
Termination Date, and the Employer thereafter will have no further obligation to
the Employee under this Agreement, other than for payment of any amounts accrued
and vested under any employee benefit plans or programs of the Related Parties
and any payments or benefits required to be made or provided under applicable
law. Without limiting the generality of the foregoing, any rights the Employee's
beneficiary(ies) may have to the proceeds of any life insurance arrangement set
forth in Section 4.3 will be in lieu of any special entitlement to severance pay
or benefits upon the Employee's death.

     6.2 Disability. In the event of the Employee's termination by reason of
Disability pursuant to Section 5.5, the Employee will continue to receive his
Base Salary and participate in applicable employee benefit plans or programs of
the Related Parties (on an equivalent basis to Section 6.4(a)(iv) below) through
the Termination Date, subject to offset dollar-for-dollar by the amount of any
disability income payments provided to the Employee under any disability policy
or program funded by any of the Related Parties, and will receive (a) the
Employee's accrued but unpaid Base Salary through the Termination Date paid in a
lump sum within thirty (30) days following the Termination Date, (b) any accrued
but unpaid Bonus, which Bonus will be payable at such time as the bonuses of
other executive officers of the Company are payable, (c) the Employee's Pro-Rata
Bonus, payable at such time as bonuses for the annual period are paid to other
executive officers of the Company, and (d) any other amounts that may be
reimbursable by the Employer to the Employee as expressly provided under this
Agreement paid in a lump sum within thirty (30) days following the Termination
Date, and the Employer thereafter will have no further obligation to the
Employee under this Agreement, other than for payment of any amounts accrued and
vested under any employee benefit plans or programs of the Related Parties and
any payments or benefits required to be made or provided under applicable law.

     6.3 By the Employer for Cause or the Employee Without Good Reason. If the
Employee's employment is terminated by the Employer for Cause, or if the
Employee terminates his employment other than for Good Reason, the Employee will
receive (a) the Employee's accrued but unpaid Base Salary through the

          Salary through the Termination Date paid in a lump sum within thirty
          (30) days following the Termination Date, (b) any accrued but unpaid
          Bonus, which Bonus will be payable at such time as the bonuses of

               (ii) twenty-four (24) monthly payments each in an amount equal to
          one-twelfth (1/12) of the Employee's annual Base Salary at the highest
          rate in effect at any time during the thirty-six (36)-month period
          prior to the Termination Date plus the average annual Bonus of the two
          (2) years preceding the Termination Date, commencing with the calendar
          month immediately following the calendar month in which the
          Termination Date occurs, it being agreed that for purposes hereof, the
          Employee's Base Salary during the first twelve (12) months following
          the Effective Date will be deemed to be $200,000;

               (iii) a cash amount equal to the Employee's Pro-Rata Bonus for
          the fiscal year in which the Termination Date occurs, payable at such

               (iv) the Employer will pay the full cost of the Employee's COBRA
          continuation coverage for such period, as such coverage is required to
          be continued under applicable law; provided, however, that,
          notwithstanding the foregoing, the benefits described in this Section
          6.4(a)(iv) may be discontinued prior to the end of the period provided
          in this subsection (iv) to the extent, but only to the extent, that
          the Employee receives substantially similar benefits from a subsequent
          employer ("COBRA Benefit").

          (b) Change of Control Benefits. Subject to the provisions of Section
     6.4(d), if within the one (1) year period following the occurrence of a
     Change of Control, the Employer terminates the Employee's employment
     without Cause, or the Employee terminates his employment for Good Reason,
     then, in lieu of the Severance Benefits under Section 6.4(a), the Employee
     will be entitled to benefits (the "Change of Control Benefits") identical

          beneficial ownership (within the meaning of Rule 13d-3 promulgated
          under the Exchange Act) of 35% or more of either (A) the

          voting securities of Legacy entitled to vote generally in the election
          of directors (the "Outstanding Legacy Voting Securities"); provided,
          however, that, for purposes of this Section 6.4(c)(i), the following
          acquisitions will not constitute a Change of

                                       -6-

<PAGE>

          Control: (A) any acquisition directly from Legacy, (B) any acquisition

          acquisition of shares from Legacy arising out of or in connection with
          an IPO or private placement of Legacy's securities;

               (ii) Any time at which individuals who, as of the date hereof,
          constitute the Board (the "Incumbent Board") cease for any reason to
          constitute at least a majority of the Board; provided, however, that
          (A) any individual becoming a director subsequent to the date hereof
          whose election, or nomination for election by Legacy's Unitholders,
          was approved by a vote of at least a majority of the directors then
          comprising the Incumbent Board will be considered as though such
          individual were a member of the Incumbent Board, but excluding, for
          this purpose, any such individual whose initial assumption of office
          occurs as a result of an actual or threatened election contest with
          respect to the election or removal of directors or other actual or
          threatened solicitation of proxies or consents by or on behalf of a
          Person other than the Board and (B) any individual becoming a director
          subsequent to the date hereof whose election resulted from Legacy's
          failure to file a registration statement within 240 days of the

          exchange or consolidation or similar corporate transaction involving

          assets or equity interests of another entity by Legacy or any of its
          subsidiaries (each, a "Business Combination"), in each case unless,
          following such Business Combination, (A) all or substantially all of
          the individuals and entities that were the beneficial owners of the
          Outstanding Legacy Equity and the Outstanding Legacy Voting Securities
          immediately prior to such Business Combination beneficially own,
          directly or indirectly, more than 50% of the then-outstanding equity
          interests and the combined voting power of the then-outstanding voting
          securities entitled to vote generally in the election of directors, as
          the case may be, of the corporation resulting from such Business
          Combination (including, without limitation, a corporation or other
          entity that, as a result of such transaction, owns Legacy or all or
          substantially all of Legacy's assets either directly or through one or
          more subsidiaries) in substantially the same proportions as their
          ownership immediately prior to such Business Combination of the
          Outstanding Legacy Equity and the Outstanding Legacy Voting
          Securities, as the case may be, (B) no Person (excluding any
          corporation resulting from such Business Combination or any employee
          benefit plan (or related trust) of Legacy or such corporation or other
          entity resulting from such Business Combination) beneficially owns,
          directly or indirectly, 35% or more of, respectively, the
          then-outstanding equity interests of the corporation or other entity
          resulting from such Business Combination or the combined voting power
          of the then-outstanding voting securities of such corporation or other
          entity, except to the extent that such ownership existed prior to the
          Business Combination, and (C) at least a majority of the members of
          the board of directors of the corporation or equivalent body of any
          other entity resulting from such Business Combination

                                       -7-

          were members of the Incumbent Board at the time of the execution of
          the initial agreement or of the action of the Board providing for such
          Business Combination; or

               (iv) Consummation of a complete liquidation or dissolution of
          Legacy.

          (d) Conditions to Receipt of Severance Benefits.

               (i) Release. As a condition to receiving any Severance Benefits
          or Change of Control Benefits to which the Employee may otherwise be
          entitled under Section 6.4(a) or Section 6.4(b), the Employee will
          execute a release (the "Release"), which will include an affirmation
          of the restrictive covenants set forth in Section 7 and a
          non-disparagement provision, in form and substance satisfactory to the
          Employer, of any claims, whether arising under federal, state or local
          statute, common law or otherwise, against the Employer and the Related
          Parties which arise or may have arisen on or before the date of the
          Release, other than any claims under this Agreement or any rights to
          indemnification from the Employer and the Related Parties pursuant to
          any provisions of the Related Parties' organizational documents or any
          directors and officers liability insurance policies maintained by any
          of the Related Parties. If the Employee fails or otherwise refuses to
          execute a Release within a reasonable time after the Employer's
          request to do so, and in all events prior to the date on which such
          benefits are to be first paid to him, the Employee will not be
          entitled to any Severance Benefits or Change of Control Benefits, as
          the case may be, or any other benefits provided under this Agreement
          and the Employer will have no further obligations with respect to the
          provision of those benefits except as may be required by law.

               (ii) Limitation on Benefits. If, following a termination of
          employment that gives the Employee a right to the payment of Severance
          Benefits under Section 6.4(a) or Section 6.4(b), the Employee violates
          in any material respect any of the covenants in Section 7 or as
          otherwise set forth in the Release, the Employee will have no further
          right or claim to any payments or other benefits to which the Employee
          may otherwise be entitled under Section 6.4(a) or Section 6.4(b) from
          and after the date on which the Employee engages in such activities
          and the Employer will have no further obligations with respect to such
          payments or benefits, and the covenants in Section 7 will nevertheless
          continue in full force and effect.

     6.5 Severance Benefits Not Includable for Employee Benefits Purposes.
Except to the extent the terms of any applicable benefit plan, policy or program
provide otherwise, any benefit programs of any of the Related Parties that takes
into account the Employee's income will exclude any and all Severance Benefits
and Change of Control Benefits provided under this Agreement.

     6.6 Exclusive Severance Benefits. The Severance Benefits payable under
Section 6.4(a) or the Change of Control Benefits payable under Section 6.4(b),
if they become applicable under the terms of this Agreement, will be in lieu of
any other severance or similar benefits that would otherwise be payable under
any other agreement, plan, program or policy of the Employer.

                                       -8-

     6.7 Additional Payments by the Employer. Notwithstanding anything in this
Agreement to the contrary, in the event that any benefits payable or otherwise
provided under this Agreement would be

          (a) subject to the excise tax imposed by Section 4999 of the Internal
     Revenue Code of 1986, as amended (the "Code"), (such excise tax referred to
     in this Agreement as the "Excise Tax"), then the Board may, in its sole
     discretion, provide for the payment of, or otherwise reimburse the Employee
     for, an amount up to such Excise Tax and any related taxes, fees or
     penalties thereon as the Board may consider to be customary and appropriate
     for a comparable public company; or

          (b) deemed to constitute non-qualified deferred compensation subject
     to Section 409A of the Code, the Employer will have the discretion to
     adjust the terms of such payment or benefit as it deems necessary to comply
     with the requirements of Section 409A to avoid the imposition of any excise
     tax or other penalty with respect to such payment or benefit under Section
     409A of the Code.

7. RESTRICTIVE COVENANTS.

     7.1 Confidential Information. The Employee hereby acknowledges that in
connection with his employment by the Employer he has been provided and may in
the future be provided Confidential Information (as defined below) (including,
without limitation, procedures, memoranda, notes, records and customer and
supplier lists whether such information has been or is made, developed or
compiled by the Employee or otherwise has been or is made available to him)
regarding the business and operations of the Related Parties. The Employee
further acknowledges that such Confidential Information is unique, valuable,
considered trade secrets and deemed proprietary by the Related Parties. For
purposes of this Agreement, "Confidential Information" includes, without
limitation, any information heretofore or hereafter acquired, developed or used
by any of the Related Parties relating to Business Opportunities or Intellectual
Property or other geological, geophysical, economic, financial or management
aspects of the business, operations, properties or prospects of the Related
Parties, whether oral or in written form. The Employee agrees that all
Confidential Information is and will remain the property of one or more of the
Related Parties. The Employee further agrees, except for disclosures occurring
in the good faith performance of his duties for the Related Parties, during the
Employment Term and for a period of two (2) years after the Termination Date, to
hold in the strictest confidence all Confidential Information, and not to,
directly or indirectly, duplicate, sell, use, lease, commercialize, disclose or
otherwise divulge to any person or entity any portion of the Confidential
Information or use any Confidential Information for his own benefit or profit or
allow any person, entity or third party, other than the Related Parties and
authorized executives of the same, to use or otherwise gain access to any
Confidential Information. The Employee will have no obligation under this
Agreement with respect to any information that becomes generally available to
the public other than as a result of a disclosure by the Employee or his agent
or other representative or becomes available to the Employee on a
non-confidential basis from a source other than the Related Parties. Further,
the Employee will have no obligation under this Agreement to keep confidential
any of the Confidential Information to the extent that a disclosure of it is
required by law or is consented to by the Employer, the Company or Legacy;
provided, however, that if and when such a disclosure is required by law, the
Employee promptly will provide the Employer with notice of such requirement, so
that an appropriate protective order may be sought.

               (ii) all investments made by the Employee (whether in his own
          name or in the name of any family members or other nominees or made by
          the Employee's controlled affiliates), which relate to the leasing,
          acquisition, exploration, production, gathering or marketing of
          hydrocarbons and related products will be made solely through the
          Related Parties, unless approved in writing by a majority of the
          independent members of the Board of Directors or unless such activity
          is set forth on Exhibit A; and the Employee will not (directly or

          that is in direct competition with the business of the Related Parties
          in the leasing, acquiring, exploring, producing, gathering or
          marketing of hydrocarbons and related products; provided that, this
          subsection (ii) will not preclude the Employee from making investments
          in securities of oil and gas companies which are registered on a
          national stock exchange, if (A) the aggregate amount owned by the
          Employee and all family members and affiliates does not exceed 5% of
          such company's outstanding securities, and (B) the aggregate amount
          invested in such investments by the Employee and all family members
          and affiliates after the date hereof does not exceed $5,000,000.

          (c) Not Applicable Following Change of Control Termination. The
     Employee will not be subject to the covenants contained in this Section 7.3
     and such covenants will not be enforceable against the Employee from and
     after the date that the Employee's employment is terminated within one (1)
     year after a Change of Control.

     7.4 Non-Solicitation. During the Employment Term and for a period of
twenty-four (24) months after the Termination Date, the Employee will not,
whether for his own account or for the account of any other Person (other than
the Related Parties), intentionally solicit, endeavor to entice away from the
Related Parties, or otherwise interfere with the relationship of the Related
Parties with, (a) any person who is employed by the Related Parties (including
any independent sales representatives or organizations), or (b) any client or
customer of the Related Parties.

     7.5 Assignment of Developments. The Employee assigns and agrees to assign
without further compensation to the Employer and its successors, assigns or
designees, all of the Employee's right, title and interest in and to all
Business Opportunities and Intellectual Property (as those terms are defined
below), and further acknowledges and agrees that all Business Opportunities and
Intellectual Property constitute the exclusive property of the Employer.

     For purposes of this Agreement, "Business Opportunities" means all business
ideas, prospects, proposals or other opportunities pertaining to the lease,
acquisition, exploration, production, gathering or marketing of hydrocarbons and
related products and the exploration potential of geographical areas on which
hydrocarbon exploration prospects are located, which are developed by the
Employee during the Employment Term, or originated by any third party

                                      -11-

<PAGE>

and brought to the attention of the Employee during the Employment Term,
together with information relating thereto (including, without limitation,
geological and seismic data and interpretations thereof, whether in the form of
maps, charts, logs, seismographs, calculations, summaries, memoranda, opinions
or other written or charted means).

     For purposes of this Agreement, "Intellectual Property" shall mean all
ideas, inventions, discoveries, processes, designs, methods, substances,
articles, computer programs and improvements (including, without limitation,
enhancements to, or further interpretation or processing of, information that
was in the possession of the Employee prior to the date of this Agreement),
whether or not patentable or copyrightable, which do not fall within the
definition of Business Opportunities, which the Employee discovers, conceives,
invents, creates or develops, alone or with others, during the Employment Term,
if such discovery, conception, invention, creation or development (A) occurs in
the course of the Employee's employment with the Employer, or (B) occurs with
the use of any of the time, materials or facilities of the Related Parties, or
(C) in the good faith judgment of the Board, relates or pertains in any material
way to the purposes, activities or affairs of the Related Parties.

     7.6 Injunctive Relief. The Employee acknowledges that a breach of any of
the covenants contained in this Section 7 may result in material, irreparable
injury to the Employer for which there is no adequate remedy at law, that it
will not be possible to measure damages for such injuries precisely and that, in
the event of such a breach or threat of breach, the Employer will be entitled to
obtain a temporary restraining order and/or a preliminary or permanent
injunction restraining the Employee from engaging in activities prohibited by
this Section 7 or such other relief as may be required to specifically enforce
any of the covenants in this Section 7. To the extent that the Employer seeks a
temporary restraining order (but not a preliminary or permanent injunction), the
Employee agrees that a temporary restraining order may be obtained ex parte.

     7.7 Adjustment of Covenants. The parties consider the covenants and
restrictions contained in this Section 7 to be reasonable. However, if and when
any such covenant or restriction is found to be void or unenforceable and would
have been valid had some part of it been deleted or had its scope of application
been modified, such covenant or restriction will be deemed to have been applied
with such modification as would be necessary and consistent with the intent of
the parties to have made it valid, enforceable and effective.

     7.8 Forfeiture Provision.

          (a) Detrimental Activities. If the Employee engages in any activity
     that violates any covenant or restriction contained in this Section 7, in
     addition to any other remedy the Employer may have at law or in equity, (i)
     the Employee will be entitled to no further payments or benefits from the
     Employer under this Agreement or otherwise, except for any payments or
     benefits required to be made or provided under applicable law, (ii) all
     unexercised Unit options, restricted Units and other forms of equity
     compensation held by or credited to the Employee will terminate effective
     as of the date on which the Employee engages in that activity, unless
     terminated sooner by operation of another term or condition of this
     Agreement or other applicable plans and agreements, and (iii) any exercise,
     payment or delivery pursuant to any equity compensation award that occurred
     within one year prior to the date on which the Employee engages in that
     activity may be rescinded within one year after the first date that a
     majority of the members of the Board first became aware that the Employee
     engaged in that activity. In the event of any such rescission, the Employee
     will pay to the

                                      -12-

<PAGE>

     Employer the amount of any gain realized or payment received as a result of
     the rescinded exercise, payment or delivery, in such manner and on such
     terms and conditions as may be required.

          (b) Right of Set-Off. The Employee consents to a deduction from any
     amounts the Employer owes the Employee from time to time (including amounts
     owed as wages or other compensation, fringe benefits, or vacation pay, as
     well as any other amounts owed to the Employee by the Employer), to the
     extent of the amounts the Employee owes the Employer under Section 7.8(a)
     above. Whether or not the Employer elects to make any set-off in whole or
     in part, if the Employer does not recover by means of set-off the full
     amount the Employee owes, calculated as set forth above, the Employee
     agrees to pay immediately the unpaid balance to the Employer. In the
     discretion of the Board, reasonable interest may be assessed on the amounts
     owed, calculated from the later of (i) the date the Employee engages in the
     prohibited activity and (ii) the applicable date of exercise, payment or
     delivery.

8. MISCELLANEOUS.

     8.1 Assignment; Successors; Binding Agreement. This Agreement may not be
assigned by either party, whether by operation of law or otherwise, without the
prior written consent of the other party, except that any right, title or
interest of the Employer arising out of this Agreement may be assigned to any
corporation or entity controlling, controlled by, or under common control with
the Employer, or succeeding to the business and substantially all of the assets
of the Employer or any affiliates for which the Employee performs substantial
services. Subject to the foregoing, this Agreement will be binding upon and will
inure to the benefit of the parties and their respective heirs, legatees,
devisees, personal representatives, successors and assigns.

     8.2 Modification and Waiver. Except as otherwise provided below, no
provision of this Agreement may be modified, waived, or discharged unless such
waiver, modification or discharge is duly approved by the Board and is agreed to
in writing by the Employee and such officer(s) as may be specifically authorized
by the Board to effect it. No waiver by any party of any breach by any other
party of, or of compliance with, any term or condition of this Agreement to be
performed by any other party, at any time, will constitute a waiver of similar
or dissimilar terms or conditions at that time or at any prior or subsequent
time.

     8.3 Entire Agreement. This Agreement embodies the entire understanding of
the parties hereof, and, upon the Effective Date, will supersede all other oral
or written agreements or understandings between them regarding the subject
matter hereof. No agreement or representation, oral or otherwise, express or
implied, with respect to the subject matter of this Agreement, has been made by
either party which is not set forth expressly in this Agreement.

     8.4 Governing Law. The validity, interpretation, construction and
performance of this Agreement will be governed by the laws of the State of Texas
other than the conflict of laws provision thereof.

     8.5 Consent to Jurisdiction and Service of Process.

          (a) Section 7 Disputes. In the event of any dispute, controversy or
     claim between the Employer and the Employee arising out of or relating to
     the interpretation, application or enforcement of the provisions of Section
     7, the Employer and the

                                      -13-

<PAGE>

     Employee agree and consent to the personal jurisdiction of the state and
     local courts of Midland County, Texas and/or the United States District
     Court for the Western District of Texas for resolution of the dispute,
     controversy or claim, and that those courts, and only those courts, will
     have jurisdiction to determine any dispute, controversy or claim related
     to, arising under or in connection with Section 7 of this Agreement. The
     Employer and the Employee also agree that those courts are convenient
     forums for the parties to any such dispute, controversy or claim and for
     any potential witnesses and that process issued out of any such court or in
     accordance with the rules of practice of that court may be served by mail
     or other forms of substituted service to the Employer at the address of its
     principal executive offices and to the Employee at his last known address
     as reflected in the Employer's records.

          (b) Disputes Other Than Under Section 7. In the event of any dispute
     relating to this Agreement, other than a dispute relating solely to Section
     7, the parties will use their best efforts to settle the dispute, claim,
     question, or disagreement. To this effect, they will consult and negotiate
     with each other in good faith and, recognizing their mutual interests,
     attempt to reach a just and equitable solution satisfactory to both
     parties. If such a dispute cannot be settled through negotiation, the
     parties agree first to try in good faith to settle the dispute by mediation
     administered by the American Arbitration Association under its Commercial
     Mediation Rules before resorting to arbitration, litigation, or some other
     dispute resolution procedure. If the parties do not reach such solution
     through negotiation or mediation within a period of sixty (60) days, then,
     upon notice by either party to the other, all disputes, claims, questions,
     or differences will be finally settled by arbitration administered by the
     American Arbitration Association in accordance with the provisions of its
     Commercial Arbitration Rules. The arbitrator will be selected by agreement
     of the parties or, if they do not agree on an arbitrator within thirty (30)
     days after either party has notified the other of his or its desire to have
     the question settled by arbitration, then the arbitrator will be selected
     pursuant to the procedures of the American Arbitration Association (the
     "AAA") in Midland, Texas. The determination reached in such arbitration
     will be final and binding on all parties. Enforcement of the determination
     by such arbitrator may be sought in any court of competent jurisdiction.
     Unless otherwise agreed by the parties, any such arbitration will take
     place in Midland, Texas, and will be conducted in accordance with the
     Commercial Arbitration Rules of the AAA.

     8.6 Withholding of Taxes. The Employer will withhold from any amounts
payable under the Agreement all federal, state, local or other taxes as legally
will be required to be withheld.

     8.7 Notices. All notices, consents, waivers, and other communications under
this Agreement must be in writing and will be deemed to have been duly given
when (a) delivered by hand (with written confirmation of receipt), (b) sent by
facsimile (with written confirmation of receipt), provided that a copy is mailed
by registered mail, return receipt requested, or (c) when received by the
addressee, if sent by a nationally recognized overnight delivery service
(receipt requested), in each case to the appropriate addresses and facsimile

recorded address of that party.

     8.8 Severability. The invalidity or unenforceability of any provision or
provisions of this Agreement will not affect the validity or enforceability of
any other provision of this Agreement, which will remain in full force and
effect.

     8.9 Counterparts. This Agreement may be executed in one or more
counterparts, each of which will be deemed to be an original but all of which
together will constitute one and the same instrument.

     8.10 Headings. The headings used in this Agreement are for convenience
only, do not constitute a part of the Agreement, and will not be deemed to
limit, characterize, or affect in any way the provisions of the Agreement, and
all provisions of the Agreement will be construed as if no headings had been
used in the Agreement.

     8.11 Construction. As used in this Agreement, unless the context otherwise
requires: (a) the terms defined herein will have the meanings set forth herein
for all purposes; (b) references to "Section" are to a section hereof; (c)
"include," "includes" and "including" are deemed to be followed by "without
limitation" whether or not they are in fact followed by such words or words of
like import; (d) "writing," "written" and comparable terms refer to printing,
typing, lithography and other means of reproducing words in a visible form; (e)
"hereof," "herein," "hereunder" and comparable terms refer to the entirety of

regulation are referred to as amended or supplemented from time to time (and, in
the case of a statute or regulation, to any successor provision).

     8.12 Capacity; No Conflicts. The Employee represents and warrants to the
Employer that: (i) he has full power, authority and capacity to execute and
deliver this Agreement, and to perform his obligations hereunder, (ii) such
execution, delivery and performance will not (and with the giving of notice or
lapse of time, or both, would not) result in the breach of any agreement or
other obligation to which he is a party or is otherwise bound, and (iii) this
Agreement is his valid and binding obligation, enforceable in accordance with
its terms.
