to sixty-six and two-thirds percent (66-2/3%) of the Net Income
          attributable to each Plan Year’s or Partial Plan Year’s accounting
          pool shall be available for allocation among any eligible Participants who have

determined pursuant to Section 5.1 (or their beneficiaries) and who are either
employed by the Company as of the last day of the latest Plan Year or are vested in
accordance with Section 5.4 in accordance with their original sharing ratios in each
such accounting pool (the “Original Sharing Ratios”);
provided, however, that, in the case of Pre-2004 Pools (as defined in Section 5.4(b)
below), the Original Sharing Ratios shall be increased proportionately to account for the
forfeiture of interests because of (a) the termination of employment of Participants
prior to becoming fully vested in accordance with Section 5.4, or (b) those
matters specified in Section 5.5; provided further, that, in the case of Post-2003

A vested Participant shall continue
to share in the distribution of Net Income or Net Proceeds (as set forth in Section 3.3)
from each Post-2003 Pool in which he was previously allocated an interest pursuant to the
terms of this Plan in the same manner as Participants who are employed by the Company,
based upon his vested percentage of his participation in such Post-2003 Pool at the date
of his termination of employment and his percentage of the Net Income and Net Proceeds (as
set forth in Section 3.3) of each such Post-2003 Pool as of the end of the Plan Year
immediately preceding or coincident with the date of his termination of employment.
Notwithstanding any other provision of this Plan to the contrary, upon a
Participant’s reaching age 65 while continuously employed by the Company, such
Participant’s right to continue to participate in each Post-2003 Pool in which he
originally shared shall become fully vested. 

            (d)      If
a Participant who is an Employee dies or becomes disabled during his           employment
(such qualifying disability to be determined by the Committee in its           sole
discretion) prior to becoming fully vested in accordance           with subsections
(b) or (c) above, as applicable, such Participant (or his           beneficiary) shall
nevertheless be fully vested for purposes of future           distributions from all
accounting pools relating to Plan Years in which he was           previously allocated an
interest pursuant to the terms of this Plan.  

        5.5    
Forfeiture-Termination for Cause.  

            (a)      If
a Participant’s employment with the Company is terminated for cause, as
          determined by the Company in its sole discretion, the Participant, regardless
of           his or her vested percentage, shall forfeit all rights to any further
          distributions or payments from the Plan as of the date of such termination.  

-13- 

            (b)    
        If a vested non-Employee Participant is later determined by the Company in its
          sole discretion to have engaged in any activity which would be grounds for
          termination for cause while employed by the Company, such Participant shall,
          upon such determination, forfeit all rights to any further distributions or
          payments from the Plan.  

ARTICLE VI

Administrative Responsibilities 

        6.1    
     The Company. 

            The
Company  shall be  responsible  for:  (a) keeping  accurate  books and accounts with
respect to properties contributed to the Plan and all Net Income and Net Proceeds which
it receives attributable to properties which have been allocated to the Plan; (b) keeping
accurate books and records with respect to its Employees and their Compensation and
furnishing such data to the Committee; and (c) making payments to Plan Participants
and their beneficiaries in accordance with the provisions of the Plan. 

        6.2    
The Committee.  

            The
Committee shall administer the Plan and shall have all powers necessary for that purpose,
including, but not by way of limitation, power to specify the economic interest
contributed, and percentages of Net Income and Net Proceeds allocated, to the Plan each
Plan Year or Partial Plan Year, to interpret the Plan, to determine the eligibility,

Committee shall direct all distributions in accordance with the provisions of the Plan
and shall maintain all Plan records except records required to be kept by the Company. 

        6.3    
Indemnification of Committee Members.  

            The
Company shall indemnify each member of the Committee against any and all claims, loss,

or willful misconduct of such person.

ARTICLE VIII

Termination and
Amendment 

        7.1    
     Termination of Plan; Change in Control; Accelerated Vesting. 

            The
Company  presently  intends to continue the Plan  indefinitely,  but the continuance of
the Plan is not assumed as a contractual obligation and the Company may terminate the
Plan at any time by delivering written notice of termination to the Committee and each
Participant and beneficiary then entitled to receive distributions from the Plan. Upon
(a) the voluntary termination of the Plan by the Company, or (b) a Change in Control (as
defined in Section 1.4), the interests of all Participants in the Plan who are Employees
at such time shall become 100% vested as to all Plan Years or the Partial Plan Year in
which such Participant was allocated an interest pursuant to the terms of this Plan.
Further, upon the voluntary termination of the Plan by the Company or a Change in Control
(as defined in Section 1.5), all remaining oil and gas properties in the Plan which are
categorized as proven undeveloped reserves previously contributed to the Plan as a
Contributed Economic Interest but not allocated to a particular Plan Year shall be
allocated (together with the allocation of Net Income and Net Proceeds, if any, as set
forth in Sections 4.2 and 3.3, respectively) to the Partial Plan Year established as the
result of such voluntary termination or Change in Control and the interests of all
Participants in the Plan who are Employees at such time shall become 100% vested as to
such Partial Plan Year Net Income and such remaining properties.  

        7.2    
     Distributions Upon Voluntary Termination or Change in Control. 

            (a)              Upon
voluntary termination of the Plan by the Company, (i) the fair market value           of
the existing interest of each non-Employee Participant (or beneficiary           thereof)
as of the date of such voluntary termination shall be distributed in           one lump
sum and (ii) the fair market value of the vested interest of each           Employee
Participant as described in Section 7.1 as of the date of such           voluntary
termination shall be distributed in one lump sum, in each case twelve           (12)
months after the date of such termination. The determination of fair market
          value shall be made by the Company, using the valuation reports, discount rates
          and other factors then being used by the Company for the purchase of oil and
gas           properties from third parties. This provision shall not be effective unless
all           other plans required to be aggregated with this Plan under U.S. Internal
Revenue           Code Section 409A are also terminated and no similar plan is adopted by
the           Company within five (5) years of the date of termination.  

-15- 

        (b)              Upon
a Change in Control (as defined in Section 1.5), the Plan shall           automatically
terminate, and (i) the existing interest of each non-Employee           Participant (or
beneficiary thereof), valued in accordance with           Section 7.2(a) as of the
date of such Change in Control, shall be           distributed in one lump sum and (ii)
the vested interest of each Employee           Participant as described in Section 7.1,
valued in accordance with Section           7.2(a) as of the date of such Change in
Control, shall be distributed in one           lump sum, in each case as soon as
practicable after the date of such Change in           Control but no later than one (1)
month after the date of such Change in           Control. 

        7.3    
Amendment by Company.  

            The
Company may at any time amend the Plan in any respect by action of its Board of
Directors, but no amendment shall be made which would have the effect of materially and
adversely affecting the interest of any person under the Plan with respect to then
existing Pools.  

ARTICLE VIII

Miscellaneous 

        8.1    
Right to Dismiss Employees.  

            The
Company may  terminate  the  employment  of any Employee as freely and with the same
effect as if this Plan were not in existence.  

        8.2    
Withholding of Taxes, Etc.  

            The
 Company  shall  withhold  from  all  payments  to  Participants  and  beneficiaries
hereunder, and pay to the appropriate governmental authority, all amounts of income and
employment taxes and other authorized deductions and amounts which are required by
applicable law and regulation to be withheld from wage payments to Employees of the
Company.  

        8.3    
Source of Benefits.  

            All
 benefits  payable  under the Plan shall be paid solely  from the general  assets of the
Company and no allocation of royalty interest or income on the books of the Company shall
be deemed to create a separate fund or any ownership interest on the part of the Plan in
any properties being used to measure Plan income or in any production from such
properties. The right of a Participant or his beneficiary to receive a distribution
hereunder shall be an unsecured claim.  

-16- 

        8.4    
Ownership of Properties.  

            Nothing
 contained  in this Plan shall in any way  restrict  the right of the Company to sell,
 transfer,  mortgage,  encumber or otherwise  deal with the  properties  giving rise to
the revenues  used to measure Plan income.  

        8.5    
Beneficiaries.  

            Each
Participant  shall file with the Committee a designation of the  beneficiaries  and
contingent beneficiaries to whom income attributable to his interest under the Plan shall
be paid in the event of his death on such form as may be prescribed by the Committee. The
last properly completed beneficiary designation received by the Committee while the
Participant is living shall be given effect. Such designation may be changed by the
Participant at any time and without the consent of any previously designated beneficiary.
In the absence of an effective beneficiary designation as to any portion of a Participant’s
interest under the Plan, income attributable to such interest shall be paid to the
Participant’s personal representative, but if the Committee believes that none has
been appointed within six months after the Participant’s death, the Committee may
direct that such income shall not be paid until a personal representative has been
appointed or may direct that such income shall be paid to the Participant’s
surviving spouse as defined by federal law in effect at the time the Committee makes its
decision.  

        8.6    
Non-transferability of Benefits.  

            No
 Participant  or  beneficiary  shall  have any right to assign,  alienate,  transfer,
hypothecate, encumber or anticipate his interest in any benefits under this Plan, nor
shall such benefits be subject to any legal process to levy upon or attach the same for
payment of any claim against any such Participant or beneficiary.  

        8.7    
Payments Due Minors or Incapacitated Persons.  

            If
any  person  entitled  to a payment  under the Plan is a minor,  or if the  Committee
determines that any such person is incapacitated by reason of physical or mental
disability, whether or not legally adjudicated as such, the Committee shall have the
power to cause the payments becoming due to such person to be made to his personal
representative or to another for his benefit, without responsibility of the Committee to
see to the application of such payments. The Committee shall have no responsibility to
investigate the physical or mental condition of a Participant and any determination of
disability made by the Committee shall be binding on the Participant and all other
persons. Payments made pursuant to such power shall operate as a complete discharge of
the Plan, the Company and the Committee.  

-17- 

        8.8    
Notification of Address.  

            Each
 Participant  must file with the  Company  from  time to time in  writing  his post
office address and the post office address of each of his beneficiaries and each change
of post office address. Any communication, statement or notice addressed to a Participant
or beneficiary at his last post office address filed with the Company, or as shown on the
Company’s records, will be binding on the Participant and his beneficiaries for all
purposes of the Plan. Neither the Committee nor the Company shall be required to search
for or locate a Participant or beneficiary.  

        8.9    
     Offset. 

            The
 Company  shall  have the right to offset  from any  amount  payable  hereunder  any
amount that the  Participant  owes to the  Company  without the  consent of the
 Participant  (or his  beneficiary, following the Participant's death). 

        8.10    
    Severability. 

            If
any  provision  of this Plan is or  becomes  or is deemed to be  invalid,  illegal or
unenforceable in any jurisdiction, or as to any person, payment or circumstance, under
any law the Committee deems applicable, then such provision should be construed or deemed
amended to conform to applicable laws, or if it cannot be so construed or deemed amended,
then such provision should be stricken as to such jurisdiction, person, payment or
circumstance, and the remainder of this Plan will remain in full force and effect. 

-18- 

        8.11    
Governing Law; Limitations; Venue.  

            The
construction and interpretation of this Plan shall be governed by the laws of the State
of Colorado without reference to conflict of law principles thereof. Any action or other
legal proceeding with respect to the Plan may be brought only within the period ending on
the earlier of (a) one year after the date the claimant in such action or proceeding
knows or with the exercise of reasonable care should have known of the facts giving rise
to the claim, or (b) the expiration of the applicable statute of limitations period under
applicable law. Exclusive jurisdiction over any such actions or legal proceedings shall
reside in the courts of the State of Colorado and the United States District Court
located in Denver, Colorado.
