Purpose

..   This Agreement and its attachments are not intended and shall
not  be  construed to create a joint venture or other partnership

the  Tax  Partnership (as an entity) if necessary to comply  with
the applicable Operating Agreement.

     2.02 Purpose

..   The  purpose for which this Agreement is being entered is  to
further  align  the interests of the Participants with  those  of

indirectly, by CWEI and the Participants.

     5.04

Funding of Costs and Expenses

..

     (a)   The Parties agree to pay timely the costs and expenses
allocated  and  charged  to them pursuant  to  Section  5.01  and
elsewhere herein.

(b)  To the extent that costs and expenses are allocated and
charged to Participants pursuant to Section 5.01 and elsewhere in
this Agreement, and not retained by CWEI from a distribution to
Participants pursuant to Section 5.05, CWEI shall send written
notice to the Participants (a "Contribution Notice") setting
forth (i) the date on which such additional funds shall be
payable (the "Contribution Date"), which date shall be not less
than 10 days after the date of the Contribution Notice, and (ii)
the total amount of funds required to be paid by each Participant
pursuant to this Section 5.04.  The funds required of each
Participant shall be in proportion to the number of Interests
held by such Participant.
(c)  If a Participant does not pay timely the costs and expenses
allocated and charged to such Participant (a "Non-Contributing
Party") at the time or in the manner provided in the Contribution
Notice, CWEI, in its sole discretion, may pay the costs and
expenses that the Non-Contributing Party failed to pay within 20
days after the Contribution Notice, in which case the Non-
Contributing Party, without further action on his or her part,
shall be deemed to have assigned to CWEI the economic rights to
the Interests held by the Non-Contributing Party pursuant to this
Agreement, and CWEI, as the assignee of the Non-Contributing
Party and the holder of such Interests, shall be entitled to
receive all allocations of income, gain, loss, deduction, credit
or similar items, and all distributions, to which the Non-
Contributing Party would otherwise be entitled from and after the
Contribution Date.  CWEI shall hold such Interests attributable
to the Non-Contributing Party until such time as CWEI, as the
holder of such Interests, shall have received distributions
pursuant to Section 5.05 in an aggregate amount equal to 200% of
the additional funds paid by CWEI pursuant to this Section
5.04(c), whereupon CWEI, without further action on its part,
shall be deemed to have re-assigned the economic rights to such
Interests to the Non-Contributing Party.  CWEI may use the power
of attorney set forth in Section 8.13 to reflect any assignment
pursuant to this Section 5.04(c).  Furthermore, a Non-
Contributing Party shall indemnify and hold harmless each other
Party to the fullest extent permitted by law, from and against
the costs and expenses that the Non-Contributing Party failed to
pay, including any losses, costs, liabilities, damages, and
expenses (including, without limitation, costs of suit and
attorneys' fees) paid or incurred in attempting to collect the
costs that the Non-Contributing Party failed to pay.
     5.05 Distributions of Revenues

..   Subject  to  Section 5.04(c), all revenues  relating  to  the
Designated  Property shall be distributed to the  Party  to  whom
such  revenues are allocated pursuant to Section 5.02;  provided,
however,  that  CWEI  shall,  in  lieu  of  issuing  Contribution
Notices,  be  entitled  to retain from any  distribution  to  any
Participant  an  amount  necessary to  discharge  the  costs  and
expenses  allocated to such Participant pursuant to Section  5.01
that  remains  unpaid; provided, further, that  if  Payout  would
occur  as a result of a distribution of cash funds to CWEI,  such
distribution  shall  be deemed to constitute  two  distributions:
(i)  the  first distribution shall consist of the amount of  cash
funds  necessary  to cause Payout to occur, and (ii)  the  second
distribution  shall  consist of the balance  of  the  funds  then
distributed.

     5.06 Withholding Taxes

..   CWEI  shall  at all times be entitled (but not obligated)  to
make  payments required to discharge any obligation  of  CWEI  to
withhold  or  make  payments to any governmental  authority  with
respect  to  any  federal, state or local tax  liability  of  any
Participant  for  such  taxes arising out of  such  Participant's
interest  in  the Designated Property.  The amount of  each  such
payment  made  by CWEI with respect to any Participant  shall  be
deducted  from  any  distributions  otherwise  payable  to   such
Participant   pursuant   to   this  Agreement.    Notwithstanding
anything  contained  in this Agreement to the  contrary,  in  the
event  CWEI  fails to withhold any federal, state or local  taxes
in  respect  of any Participant when required to do so (including
as  a  result of any change in law or interpretation  thereof  or
otherwise)   any  liability  incurred  by  CWEI  (including   any
interest  and  penalties) as a result of such  failure  shall  be
borne  by  such  Participant (and charged to  such  Participant's
Capital  Account), and such Participant shall indemnify and  hold
harmless  CWEI  from  and against any and  all  claims,  demands,
liabilities,  costs, damages and causes of action of  any  nature
whatsoever related to such withholding obligation.

     6.01 Maintenance of Books and Records

..   The  books  of  account  for the  Tax  Partnership  shall  be
maintained  on an accrual basis in accordance with the  terms  of
this  Agreement, except that the Capital Accounts of the  Parties
shall be maintained in accordance with Exhibit D.  The accounting
year of the Tax Partnership shall be the calendar year.

                           ARTICLE VII
                           TERMINATION

     7.01 Termination

..   This  Agreement shall terminate on the first to occur of  the
following:

     (a)  the third anniversary of Payout;

      (b)   the  election  of CWEI, in its  sole  discretion,  to
terminate this Agreement.


     7.02 Distributions upon Termination

..   Upon termination of this Agreement, CWEI shall distribute all
Designated  Property (or proceeds therefrom) to  the  Parties  as
follows:

     (a)   CWEI may sell any or all Designated Property and other
assets, including to Parties, and any resulting gain or loss from
each sale shall be computed and allocated to the Capital Accounts
of the Parties in accordance with Section 7.02(c);

(b)  With respect to all Designated Property that has not been
sold, the fair market value of such Designated Property shall be
determined by CWEI and any unrealized income, gain, loss, and
deduction inherent in such property that has not been reflected
in the Capital Accounts of the Parties previously shall be
allocated among the Parties in accordance with Section 7.02(c);
(c)  All items of income, gain, loss and deduction referred to in
Sections 7.02(a) and (b) shall be allocated among the Parties in
such a manner as to cause, to the maximum extent possible, the
positive Capital Account balance of each Party to equal the
distribution such Party would receive if the distributions upon
liquidation of the proceeds described in Section 7.02(a) and
proceeds equal in amount to the fair market value of property
described in Section 7.02(d) were made in accordance with Section
5.05 of this Agreement;
(d)  Designated Property (and proceeds therefrom) shall then be
distributed among the Parties in accordance with the positive
Capital Account balances of the Parties, as determined after
taking into account all Capital Account adjustments for the
taxable year of the Tax Partnership during which the termination
of this Agreement occurs (other than those made by reason of
distributions pursuant to this clause (d)), and those
distributions shall be made by the end of the taxable year of the
Tax Partnership during which the termination of this Agreement
occurs (or, if later, 90 days after the date of the liquidation);
(e)  It is intended that the distributions made to each Party
pursuant to this Section 7.02 be equal to the distributions to
which such Party would be entitled if liquidating distributions
were made in accordance with Section 5.05 of this Agreement.  To
the extent the Parties' positive Capital Account balances after
application of Section 7.02(c) do not correspond to the amounts
of such intended distributions, the allocations provided for in
Exhibit D for the taxable year in which the liquidation occurs
shall be adjusted, to the maximum extent possible, to produce
Capital Account balances which correspond to the amount of such
intended distributions.
All  distributions  in  kind to the Participants  shall  be  made
subject to the liability of each distributee for his, her or  its
allocable  share  of  costs, expenses and liabilities  previously
incurred  or  for which CWEI has committed prior to the  date  of
termination  and those costs, expenses and liabilities  shall  be
allocated  to  the  distributee  under  this  Section  7.02.  The
distribution  of cash or property to a Participant in  accordance
with  the  provisions of this Section 7.02 constitutes a complete
distribution to the Participant of his, her or its Interests  and
all  the  Designated Property and other assets and constitutes  a
compromise  to  which all Parties have consented. To  the  extent
that a Participant returns funds to CWEI, it has no claim against
any other Party for those funds.

     7.03 Termination

..  On  completion  of the distribution of Partnership  assets  as
provided  in  this  Agreement,  the  Tax  Partnership  shall   be
considered terminated.

                          ARTICLE VIII
                       GENERAL PROVISIONS

     8.01 Offset

..   Whenever  CWEI  is  to pay any sum to  any  Participant,  any
amounts  that  Participant owes CWEI or  its  Affiliates  may  be
deducted from that sum before payment.

     8.02 Notices

..   All notices, requests or consents required or permitted to be
given  under  this  Agreement must be in  writing  and  shall  be
considered  as  properly given if mailed by  first  class  United
States  mail,  postage  paid, and registered  or  certified  with
return  receipt  requested, or if delivered to the  recipient  in
person,  by  courier  or  by  facsimile  transmission.   Notices,
requests  and  consents shall be sent to  a  Participant  at  the
address  shown  on  its  Signature  Page  for  Participants.    A
Participant  may change its address by giving written  notice  to
CWEI.   Any notice, request or consent to CWEI shall be  sent  to
CWEI  at  its  principal place of business, to the  attention  of
Patti Hollums.

     8.03 Entire Agreement

..  This Agreement constitutes the entire agreement of the Parties
relating to the Tax Partnership and the Designated Property,  and
supersedes  all  prior  contracts  or  agreements  with   respect
thereto, whether oral or written.

     8.04 Effect of Waiver or Consent

..   A  waiver or consent, express or implied, to or of any breach
or default by any Person in the performance by that Person of its
obligations  with respect to this Agreement is not a  consent  or
waiver to or of any other breach or default in the performance by
that  Person of the same or any other obligations of that  Person
with  respect to this Agreement.  Failure on the part of a Person
to  complain of any act of any Person or to declare any Person in
default with respect to this Agreement, irrespective of how  long
that  failure  continues, does not constitute a  waiver  by  that
Person  of  its  rights with respect to that  default  until  the
applicable statute of limitations period has run.

     8.05 Amendment or Modification

          .

     (a)   Except as otherwise provided in this Section 8.05, any
amendment to this Agreement must be proposed by CWEI and approved
in  writing  by CWEI and at least a Majority in Interest  of  the
Participants within 90 days of its proposal to be effective.

(b)  CWEI may amend this Agreement without the consent of any
Participant (i) to remove or correct any inconsistency, ambiguity
or error contained herein, provided that such amendment does not
materially and adversely affect the Participants, (ii) to reflect
any Transfer or forfeiture of Interests pursuant to Sections 4.03
and 4.04 , (iii) to amend Exhibit B from time to time to amend
the Area of Interest, or (iv) to amend Exhibit C from time to
time to add additional Wells to become subject to this Agreement.
     (c)   Upon  publication of final regulations in the  Federal
Register  (or other official pronouncement), CWEI shall have  the
authority,   without   any  requirement  for   consent   by   any
Participant,  to  amend  this  Agreement  to  the   extent   CWEI
determines, in its sole discretion, is necessary (a)  to  provide
for the making and filing of any available election to obtain the
benefits  of a safe harbor corresponding to that described  under
proposed  U.S.  Treasury Regulations section  1.83-3(1)  (or  any
similar  provision)  under which the  fair  market  value  of  an
interest  that is transferred in connection with the  performance
of services is treated as being equal to the liquidation value of
that  interest,  and  (b) to reflect the agreement  of,  and  the
requirement  that,  the Tax Partnership and all  of  the  Parties
comply with all of the requirements set forth in such regulations
and  Notice  2005-43 (and any other guidance to  a  substantially
similar effect provided by the IRS with respect to such election)
with respect to all interests transferred in connection with  the
performance of services while the election remains effective.

     8.06 Binding Effect

..   Subject  to the restrictions on Transfers set forth  in  this
Agreement, this Agreement is binding on and inures to the benefit
of the Parties and their respective successors and assigns.

     8.07 Governing Law; Severability

..   THIS  AGREEMENT  IS  GOVERNED BY AND SHALL  BE  CONSTRUED  IN
ACCORDANCE  WITH  THE  LAW OF THE STATE OF TEXAS,  EXCLUDING  ANY
CONFLICT  OF  LAWS  RULE  OR  PRINCIPLE  THAT  MIGHT  REFER   THE
GOVERNANCE  OR THE CONSTRUCTION OF THIS AGREEMENT TO THE  LAW  OF
ANOTHER JURISDICTION.  If any provision of this Agreement or  its
application  to  any Person or circumstance is  held  invalid  or
unenforceable to any extent, the remainder of this Agreement  and
the   application   of  that  provision  to  other   Persons   or
circumstances shall not be affected and that provision  shall  be
enforced to the fullest extent permitted by law.

     8.08 Further Assurances

..   In  connection  with  this  Agreement  and  the  transactions
contemplated  by  it, each Party shall execute  and  deliver  any
additional  documents and instruments and perform any  additional
acts  that  may  be  necessary or appropriate to  effectuate  and
perform the provisions of this Agreement and those transactions.

     8.09 Waiver of Certain Rights

..   Except  for CWEI, each Party irrevocably waives any right  it
may have to maintain any action for partition of the property  of
the Tax Partnership.

     8.10 Insurance

          .   CWEI  may purchase and maintain insurance or  enter
into  other  arrangements on behalf of a Participant against  any
liability  asserted against the Participant and incurred  by  the
Participant  in  that capacity or arising out of this  Agreement.
In  the  absence of actual fraud, the judgment of CWEI as to  the
terms  and  conditions of the insurance or other arrangement  and
the  identity of the insurer or other Person participating in  an
arrangement  shall  be  conclusive, and the  insurance  or  other
arrangement  shall  not be voidable and shall  not  subject  CWEI
approving the insurance or other arrangement to liability, on any
ground, regardless of whether CWEI will be a beneficiary.

     8.11 Indemnification

          .

     (a)  CWEI agrees to indemnify and hold harmless the Participants
(each,  an  "Indemnified Person") to the fullest extent permitted
by law, from and against all losses, costs, liabilities, damages,
and  expenses (including, without limitation, costs of  suit  and
attorneys' fees) paid or incurred in connection with or resulting
from  any  and  all  claims,  actions  or  demands  against  such
Indemnified Person that arise out of or in any way relate  to  or
are incidental to the Tax Partnership, the Designated Property or
the  business or affairs of the Tax Partnership that occurs prior
to  the  termination of this Agreement; provided,  however,  that
this  indemnity  shall not extend to (i) any bad  faith,  willful
misconduct,  or gross negligence of such Indemnified  Person,  or
(ii) the failure of such Indemnified Person to perform any of its
obligations  under  this Agreement, including without  limitation
obligations  set  forth in Sections 5.01, 5.04,  and  5.06.   THE
PARTIES  INTEND  THAT  THE  INDEMNIFIED  PERSONS  BE  INDEMNIFIED
PURSUANT  TO  THIS AGREEMENT FROM LIABILITY FOR THEIR  OWN  SOLE,
PARTIAL OR CONCURRENT NEGLIGENCE.

(b)  The indemnification rights contained in this Section 8.11
shall be cumulative of and in addition to any and all other
rights, remedies and recourses to which any Indemnified Person or
their respective heirs, personal representatives, successors and
assigns shall be entitled, whether pursuant to some other
provisions of this Agreement, at law or in equity.
(c)  CWEI shall advance to any Indemnified Person all reasonable
fees, costs and expenses (including attorneys' fees and related
costs), of defending any claim, action or demand that arises out
of or in any way relates to or is incidental to the Tax
Partnership, the Designated Property, business or affairs of the
Tax Partnership that occurs during any period in which such
Indemnified Person is an employee of CWEI; provided, that such
Indemnified Person agrees in writing to repay to the Tax
Partnership all such advances in the event that it is finally
determined that such Indemnified Person is not entitled to
indemnification hereunder with respect to such claim, action or
demand.
     8.12 CWEI Counsel

          .   CWEI  has  selected Vinson & Elkins  L.L.P.  ("CWEI
Counsel")  as legal counsel to it with respect to this Agreement.
Each   Participant  acknowledges  that  CWEI  Counsel  does   not
represent  such Participant, and that CWEI Counsel shall  owe  no
duties  directly  to such Participant.  Each Participant  further
acknowledges that, whether or not CWEI Counsel has  in  the  past
represented  or  is currently representing such Participant  with
respect  to  other  matters,  CWEI Counsel  has  not  advised  or
represented  the interests of any Participant in the negotiation,
preparation,   execution,  delivery  and  performance   of   this
Agreement.

     8.13 Power of Attorney

..   By  the  execution of this Agreement, each  Participant  does
irrevocably  constitute  and appoint CWEI,  with  full  power  of
substitution, as true and lawful attorney-in-fact and agent  with
full power and authority to act in such Participant's name, place
and  stead  and to execute all documents which such  attorney-in-
fact deems necessary or reasonably appropriate in furtherance  of
this Agreement.

     8.14 Counterparts

..   This  Agreement may be executed in any number of counterparts
(including by facsimile transmission) with the same effect as  if
all   signing   parties  had  signed  the  same  document.    All
counterparts shall be construed together and constitute the  same
instrument.

     8.15 No Employment Contract

          .    Nothing  contained  in  this  Agreement  shall  be
construed as conferring upon any Participant who is or may become
an  employee  of  CWEI  or any Affiliate of  CWEI  any  right  to
continue  in the employment of CWEI or any Affiliate of CWEI  for
any  period of time or interfere with or restrict in any way  the
rights  of  CWEI or any Affiliate of CWEI or such Participant  to
terminate the employment of such Participant at any time for  any
reason (or without any reason) whatsoever, with or without cause.
For  the  avoidance of doubt, any termination of a  Participant's
employment  with CWEI shall not affect any of such  Participant's
rights pursuant to this Agreement.

     8.16 Designation of Wells

          .   Each  of  the Parties hereby agrees that all  Wells
that  are  located within the Area of Interest that are commenced
after  the  date hereof and prior to the Cut-Off  Date  shall  be
subject  to this Agreement.  For purposes of this Agreement,  the
"Cut-Off  Date"  shall  be the date that  CWEI  identifies  in  a
written  notice delivered to each Participant indicating that  no
Wells  within  the Area of Interest commenced after  the  Cut-Off
Date  will be made subject to this Agreement.  Additionally, each
Participant acknowledges that certain circumstances may  make  it
appropriate  for  CWEI to deliver such a written  notice  to  the
Participants  and  to  enter  into  agreements  similar  to  this
Agreement  with  other  parties (which may  or  may  not  include
certain  of  the  Participants) that relate  to  Wells  that  are
located  in  the  Area of Interest but are not  subject  to  this
Agreement.

     8.17 Acknowledgement of 409A Issues.  Notwithstanding anything
herein  to  the contrary, each Participant (i) acknowledges  that
this  Agreement  and  the underlying transactions,  as  currently
structured,  may  be considered to be a deferral of  compensation
under  section 409A of the Internal Revenue Code ("section 409A")
and (ii) agrees that CWEI may, in its own discretion and upon its
own  initiative  and  without any action by  or  consent  of  the
Participants,  if existing or future guidance from  the  Internal
Revenue Service or other interpretative authority indicates  that
such  action  is  necessary or advisable, modify  this  Agreement
and/or   restructure  the  transactions  contemplated   by   this
Agreement in any manner CWEI determines is appropriate under  the
circumstances in an effort to avoid any adverse tax  consequences
for the Participants and/or CWEI that may otherwise be imposed by
section  409A  and the Treasury Regulations thereunder,  and  the
Participants hereby consent to any such action that may be  taken
by  CWEI  and  expressly ratify this Agreement as it  may  be  so
amended.

                    [Signature Pages Follow]

     IN   WITNESS   WHEREOF,  the  parties  have  executed   this

federal  and  state tax purposes, but for no other  purpose,  all
transactions  effected  by  the  Parties  with  respect  to   the

have  been effected through the Tax Partnership, rather  than  by
the Parties individually, as set out in this Article II.

     Section  2.02    Receipts, Profits, Income and  Gains.   For
purposes  of  applying  the provisions of  this  Exhibit  D,  all

received by the Tax Partnership and then to have been distributed
to  such Party by the Tax Partnership in the manner specified  in
the  Agreement.   All such items shall be taken into  account  in
computing the Tax Partnership's gross income and gain or loss, as
appropriate,  and  shall  be  allocated  among  the  Parties   in
accordance with Article III hereof.

     Section 2.03   Costs, Expenses, Deductions and Losses.   For
purposes of applying the provisions of this Exhibit D, all  costs
incurred  or  payments  made  by any  Party  in  respect  of  the
Designated  Property pursuant to the Agreement  shall  be  deemed
first  to  have  been  received  by  the  Tax  Partnership  as  a
contribution  by  the  Party incurring the  cost  or  making  the
payment  pursuant to the terms of the Agreement and then to  have
been paid, incurred or distributed by the Tax Partnership to  the
payee  or  obligee of the cost or the recipient of  the  payment.
All  such items shall be taken into account in computing the  Tax
Partnership's  basis,  depreciation,  depletion,  gross   income,
deductible  expenses, and/or gain or loss,  as  appropriate,  and
shall  be allocated among the Parties in accordance with  Article
III hereof.

     Section   2.04     Contributions  and  Distributions.    For
purposes   of  applying  the  provisions  of  this   Exhibit   D,
contributions  to  the Tax Partnership ("Capital  Contributions")
shall  include all Acquisition Costs, Well Costs, and  any  other
costs  incurred  or  payments made in respect of  the  Designated
Property  pursuant to the Agreement.  Similarly, for purposes  of
applying the provisions of this Exhibit D, distributions from the
Tax  Partnership  shall include, in the case of  any  Party,  all
receipts  by  such  Party in respect of the  Designated  Property
pursuant to the Agreement.

     Section  2.05   Debt Financing.     For purposes of applying
the  provisions  of  this  Exhibit D, unless  the  Parties  agree
otherwise  and  this  Exhibit  D  is  amended  to  reflect   such
agreement,  (a) all debt financing incurred by a Party  shall  be
for  the  sole account of that Party and shall not be  considered
debt financing of the Tax Partnership, and (b) no Tax Partnership
asset  shall be acquired by assumption of, or taking subject  to,
any debt financing.

     Section  2.06   Record Title.       For purposes of applying
the  provisions  of  this  Exhibit D,  (a)  all  legal  title  to
Designated Property held by any Party shall be deemed to be  held
by  such  Party strictly as nominee for the Tax Partnership,  (b)
all assignments made among the Parties with respect to Designated
Property  prior  to termination of the Tax Partnership  shall  be
disregarded, and (c) upon termination of the Tax Partnership each
Party holding record title to any Designated Property shall  make
such assignments as are required to comply with the provisions of
the Agreement.

                           ARTICLE III

                 ALLOCATIONS OF PROFIT AND LOSS

     Section  3.01    Allocations for  Capital  Account  and  Tax
Purposes.  Subject to Section 7.02 of the Agreement and except as
otherwise   provided  herein,  for  purposes  of  any  applicable
federal, state or local income tax law, rule or regulation  items
of  income,  gain,  deduction, loss, credit and  amount  realized
shall be allocated to the Parties as follows:

      (a)  Income from the sale of oil or gas production and  any
credits allowed by Section 29 of the Code relating thereto  shall
be  allocated  in  the  same  manner as  proceeds  therefrom  are
allocated and credited pursuant to Section 5.02 of the Agreement.

      (b)   Cost and percentage depletion deductions and the gain
or  loss  on  the  sale  or  other disposition  of  property  the
production  from which is subject to depletion (herein  sometimes
called "Depletable Property") as computed for tax purposes  shall
be  taken into account separately by the Parties rather than  the
Tax  Partnership  and, except to the extent  and  in  the  manner
provided  in Section 5.01(b) of this Exhibit D, shall not  affect
any     Party's    Capital    Account.     For    purposes     of
Section 613A(c)(7)(D) of the Code, the Tax Partnership's adjusted
basis  in  each  Depletable Property shall be  allocated  to  the
Parties  in  proportion to each Party's respective share  of  the
costs  and  expenses  which entered into  the  Tax  Partnership's
adjusted  basis  for  each Depletable Property,  and  the  amount
realized  on  the  sale or other disposition of  each  Depletable
Property shall be allocated to the Parties in proportion to  each
Party's  respective share of the proceeds from the sale or  other
disposition of such property provided for in Section 5.02 of  the
Agreement.  For purposes of allocating amounts realized upon  any
such  sale  or  disposition which are deemed to be  received  for
federal or state income tax purposes and are attributable to  Tax
Partnership indebtedness or indebtedness to which the  Depletable
Property is subject at the time of such sale or disposition, such
amounts  shall  be  allocated in the same manner  as  Partnership
proceeds  used for the repayment of such indebtedness would  have
been allocated under Section 5.02 of the Agreement.

      (c)   Items  of deduction, loss and credit not specifically
provided  for  above  (other than loss from  the  sale  or  other
disposition of Designated Property), including depreciation, cost
recovery and amortization deductions, shall be allocated  to  the
Parties in the same manner that the costs and expenses of the Tax
Partnership that gave rise to such items of deduction,  loss  and
credit were allocated pursuant to Section 5.01 of the Agreement.

      (d)   Gain from the sale or other disposition of Designated
Property  that  is not specifically provided for above  shall  be
allocated to the Parties in a manner which reflects each  Party's
allocable  share of the revenue from the sale of  the  Designated
Property provided for in Section 5.02 of the Agreement, and  loss
from the sale or other disposition of Designated Property that is
not  specifically  provided for above shall be allocated  to  the
Parties  in a manner which reflects each Party's allocable  share
of the costs and expenses of the Designated Property provided for
in Section 5.01 of the Agreement.

      (e)   All recapture of income tax deductions resulting from
the  sale  or other disposition of Designated Property  shall  be
allocated  to the Party to whom the deduction that gave  rise  to
such  recapture was allocated hereunder to the extent  that  such
Party is allocated any gain from the sale or other disposition of
such property.

      (f)  Any other items of Tax Partnership income or gain  not
specifically provided for above shall be allocated  in  the  same
manner  as  the revenue that resulted in such income or  gain  is
allocated and credited pursuant to Section 5.02 of the Agreement.

     (g)  Notwithstanding any of the foregoing provisions of this
Section 3.01 to the contrary:

          (i)   If  during any fiscal year of the Tax Partnership
     there  is a net increase in Minimum Gain attributable  to  a
     Partner   Nonrecourse  Debt  that  gives  rise  to   Partner
     Nonrecourse Deductions, each Party bearing the economic risk
     of loss for such Partner Nonrecourse Debt shall be allocated
     items  of  Partnership deductions and losses for  such  year
     (consisting   first   of  cost  recovery   or   depreciation
     deductions with respect to property that is subject to  such
     Partner Nonrecourse Debt and then, if necessary, a pro  rata
     portion  of  the Tax Partnership's other items of deductions
     and  losses, with any remainder being treated as an increase
     in  Minimum Gain attributable to Partner Nonrecourse Debt in
     the  subsequent year) equal to such Party's share of Partner
     Nonrecourse  Deductions, as determined  in  accordance  with
     applicable Regulations.

          (ii)  If  for  any  fiscal year of the Tax  Partnership
     there  is  a  net  decrease in Minimum Gain attributable  to
     Partnership  Nonrecourse Liabilities, each  Party  shall  be
     allocated items of Tax Partnership income and gain for  such
     year   (consisting  first  of  gain  recognized,   including
     Simulated Gain, from the disposition of Designated  Property
     subject  to  one or more Partnership Nonrecourse Liabilities
     and  then,  if  necessary, a pro rata  portion  of  the  Tax
     Partnership's  other  items  of  income  and  gain,  and  if
     necessary, for subsequent years) equal to such Party's share
     of  such  net  decrease (except to the extent  such  Party's
     share  of  such net decrease is caused by a change  in  debt
     structure  with such Party commencing to bear  the  economic
     risk   of  loss  as  to  all  or  part  of  any  Partnership
     Nonrecourse Liability or by such Party contributing  capital
     to  the  Tax  Partnership that the Tax Partnership  uses  to
     repay a Partnership Nonrecourse Liability), as determined in
     accordance with applicable Regulations.

          (iii)     If for any fiscal year of the Tax Partnership
     there  is a net decrease in Minimum Gain attributable  to  a
     Partner  Nonrecourse  Debt, each Party  shall  be  allocated
     items  of  Tax  Partnership income and gain  for  such  year
     (consisting  first  of gain recognized, including  Simulated
     Gain, from the disposition of Designated Property subject to
     Partner Nonrecourse Debt, and then, if necessary, a pro rata
     portion  of the Tax Partnership's other items of income  and
     gain, and if necessary, for subsequent years) equal to  such
     Party's  share  of such net decrease (except to  the  extent
     such  Party's  share of such net decrease  is  caused  by  a
     change in debt structure or by the Tax Partnership's use  of
     capital   contributed  by  such  Party  to   repay   Partner
     Nonrecourse   Debt)   as  determined  in   accordance   with
     applicable Regulations.

      (h)   CWEI shall use all reasonable efforts to prevent  any
allocation or distribution from causing a negative balance  in  a
Party's  Adjusted  Capital  Account.  Consistent  therewith,  and
notwithstanding   any  of  the  foregoing  provisions   of   this
Section 3.01 of this Exhibit D to the contrary, if for any fiscal
year  of  the  Tax  Partnership the allocation  of  any  loss  or
deduction (net of any income or gain) to any Party would cause or
increase  a  negative  balance in such Party's  Adjusted  Capital
Account  as of the end of such fiscal year (the "Deficit  Party")
after  taking into account the provisions of Section  3.01(g)  of
this  Exhibit  D, only the amount of such loss or deduction  that
reduces  the  balance to zero shall be allocated to such  Deficit
Party  and the remaining loss or deduction shall be allocated  to
the  Parties  whose  Adjusted Capital Accounts  have  a  positive
balance remaining at such time (each, a "Positive Party").  After
any   such  allocation,  any  Tax  Partnership  income  or   gain
(including  Simulated Gain) that would otherwise be allocated  to
the  Deficit  Party shall be allocated instead  to  the  Positive
Parties  up  to  an amount equal to the Tax Partnership  loss  or
deduction  allocated to each Positive Party under  the  preceding
sentence; provided, however, that no allocation of income or gain
realized shall be made under this sentence if the effect of  such
allocation would be to cause the Adjusted Capital Account of  the
Deficit  Party  to  be  less than zero.  If,  after  taking  into
account   the   allocation  in  the  first   sentence   of   this
Section  3.01(h),  the Adjusted Capital Account  balance  of  the
Deficit Party remains less than zero at the end of a fiscal year,
a pro rata portion of each item of Tax Partnership income or gain
(including  Simulated Gain) otherwise allocable to  the  Positive
Parties  for such fiscal year (or if there is no such  income  or
gain allocable to the Positive Parties for such fiscal year,  all
such  income  or gain (including Simulated Gain) so allocable  in
the  succeeding fiscal year or years) shall be allocated  to  the
Deficit  Party  in  an  amount necessary to  cause  its  Adjusted
Capital  Account  balance  to  equal  zero;  provided,  that   no
allocation  under this sentence shall have the effect of  causing
the  Positive  Party's Adjusted Capital Account to be  less  than
zero.   After  any  such  allocation, any  Tax  Partnership  gain
(including  Simulated  Gain) resulting from  the  sale  or  other
disposition  of  Designated  Property  that  would  otherwise  be
allocated  to  the Deficit Party for any fiscal year  under  this
Section  3.01 shall be allocated instead to the Positive  Parties
until  the amount of gain so allocated equals the amount of  gain
(including  Simulated Gain) previously allocated to such  Deficit
Party  under  the  preceding sentence of  this  Section  3.01(h);
provided,   however,  that  no  allocation  of  gain   (including
Simulated  Gain) shall be made under this sentence if the  effect
of such allocation would be to cause the Adjusted Capital Account
of a Deficit Party to be less than zero.

                           ARTICLE IV

                        OTHER TAX MATTERS

     Section 4.01   Tax Elections.

     (a)   For  tax purposes, the Tax Partnership shall elect  to
use  the  calendar as its taxable year, and to report income  and
loss under the accrual method of accounting.

     (b)  In connection with any Transfer or other assignment  of
an  interest  in the Tax Partnership permitted by the  terms  and
provisions of this Agreement, CWEI shall, at the written  request
of  the transferor, transferee or other successor, cause the  Tax
Partnership to make an election to adjust the basis  of  the  Tax
Partnership's property in the manner provided in sections  734(b)
and 743(b) of the Code (or any like statute or regulation then in
effect), and such transferor, transferee or other successor shall
pay  all  costs  incurred  by the Tax Partnership  in  connection
therewith,  including, without limitation, reasonable  attorneys'
and accountants' fees.

     (c)    Unless   approved  by  the  Participants,   the   Tax
Partnership shall not file any election pursuant to sections  761
or  7701  of  the Code, section 301.7701-3 of the Regulations  or
otherwise,  the  effect of which would cause the Tax  Partnership
not  to  be  treated  as  a partnership for  Federal  income  tax
purposes.

     (d)   Except as otherwise specifically provided herein, CWEI
shall  have  the sole and absolute discretion to make  any  other
available  election  under  the  Code  on  behalf  of   the   Tax
Partnership without the prior approval by the Participants.

     Section   4.02    Tax  Matters  Partner.   CWEI  is   hereby
designated  the  "tax  matters partner" of  the  Tax  Partnership
pursuant to Section 6231(a)(7) of the Code.

                            ARTICLE V

                   CAPITAL ACCOUNT MAINTENANCE

     Section   5.01     Maintenance  of  Capital  Accounts.    An
individual  Capital  Account  (a  "Capital  Account")  shall   be
maintained  by  the  Tax Partnership for each Party  as  provided
below:

     (a)   The  Capital  Account of each Party shall,  except  as
otherwise  provided  herein,  be (A)  credited  by  such  Party's
Capital  Contributions when made (net of liabilities  secured  by
contributed  property that the Tax Partnership is  considered  to
assume  or  take subject to under Section 752 of the  Code),  (B)
credited  with the amount of any item of taxable income  or  gain
and  the  amount  of any item of income or gain exempt  from  tax
allocated to such Party, (C) credited with the Party's  share  of
Simulated Gain as provided in Section 5.01(b) of this Exhibit  D,
(D)  debited by the amount of any item of tax deduction  or  loss
allocated  to such Party, (E) debited with the Party's  share  of
Simulated   Loss   and  Simulated  Depletion   as   provided   in
Section  5.01(b) of this Exhibit D, (F) debited by  such  Party's
allocable  share  of  expenditures of  the  Tax  Partnership  not
deductible in computing the Tax Partnership's taxable income  and
not  properly  chargeable as capital expenditures, including  any
non-deductible book amortizations of capitalized costs,  and  (G)
debited  by  the amount of cash or the fair market value  of  any
property distributed to such Party (net of liabilities secured by
such distributed property that such Party is considered to assume
or  take  subject to under Section 752 of the Code).  Immediately
prior  to any distribution of assets by the Tax Partnership  that
is not pursuant to a liquidation of the Tax Partnership or all or
any  portion of a Party's interest therein, the Parties'  Capital
Accounts  shall be adjusted by (X) assuming that the  distributed
assets  were  sold  by  the Tax Partnership  for  cash  at  their
respective  fair market values as of the date of distribution  by
the  Tax  Partnership and (Y) crediting or debiting each  Party's
Capital  Account  with its respective share of  the  hypothetical
gains  or losses, including Simulated Gains and Simulated Losses,
resulting from such assumed sales in the same manner as each such
Capital Account would be debited or credited for gains or  losses
on actual sales of such assets.

       (b)    The  allocation  of  basis  prescribed  by  Section
613A(c)(7)(D) of the Code and provided for in Section 3.01(b)  of
this  Exhibit  D  and each Party's separately computed  depletion
deductions  shall  not reduce such Party's Capital  Account,  but
such  Party's  Capital Account shall be decreased  by  an  amount
equal  to  the  product  of the depletion deductions  that  would
otherwise  be allocable to the Tax Partnership in the absence  of
Section 613A(c)(7)(D) of the Code (computed without regard to any
limitations  which theoretically could apply to any Party)  times
such  Party's  percentage  share of the  adjusted  basis  of  the
property  (determined under Section 3.01(b) of  this  Exhibit  D)
with  respect  to  which  such depletion is  claimed  ("Simulated
Depletion").   The  Tax  Partnership's basis  in  any  Depletable
Property  as  adjusted  from  time  to  time  for  the  Simulated
Depletion  allocable  to  all  Parties  (and  where  the  context
requires, each Party's allocable share thereof, which share shall
be  determined  in  the same manner as the  allocation  of  basis
prescribed in Section 3.01(b) of this Exhibit D) is herein called
"Simulated   Basis."   No  Party's  Capital  Account   shall   be
decreased,    however,   by   Simulated   Depletion    deductions
attributable  to  any  Depletable Property  to  the  extent  such
deductions  exceed  such  Party's  allocable  share  of  the  Tax
Partnership's  remaining Simulated Basis in such  property.   The
Tax  Partnership shall compute simulated gain ("Simulated  Gain")
or  simulated loss ("Simulated Loss") attributable to the sale or
other   disposition  of  a  Depletable  Property  based  on   the
difference  between the amount realized from such sale  or  other
disposition  and  the  Simulated  Basis  of  such  property,   as
theretofore  adjusted.  Any Simulated Gain shall be allocated  to
the  Parties and shall increase their respective Capital Accounts
in the same manner as the amount realized from such sale or other
disposition  in  excess  of  Simulated  Basis  shall  have   been
allocated  pursuant to Section 3.01(b) of this  Exhibit  D.   Any
Simulated Loss shall be allocated to the Parties and shall reduce
their respective Capital Accounts in the same percentages as  the
costs  of the property sold were allocated up to an amount  equal
to each Party's share of the Tax Partnership's Simulated Basis in
such property at the time of such sale.

      (c)   Any  adjustments  of  basis  of  Designated  Property
provided  for under Sections 734 and 743 of the Internal  Revenue
Code  and comparable provisions of state law (resulting  from  an
election  under Section 754 of the Code or comparable  provisions
of  state  law)  and  any election by an individual  Party  under
Section  59(e)(4) of the Code to amortize such Party's  share  of
intangible  drilling and development costs shall not  affect  the
Capital  Accounts  of the Parties (unless otherwise  required  by
applicable  Treasury  Regulations),  and  the  Parties'   Capital
Accounts  shall be debited or credited pursuant to the  terms  of
this Section 5.01 as if no such election had been made.

      (d)   Capital  Accounts  shall be  adjusted,  in  a  manner
consistent with this Section 5.01, to reflect any adjustments  in
items  of  Tax  Partnership income, gain, loss or deduction  that
result  from  amended  returns filed by the  Tax  Partnership  or
pursuant to an agreement by the Tax Partnership with the Internal
Revenue Service or a final court decision.

     (e)  In the case of property carried on the books of the Tax
Partnership  at an amount which differs from its adjusted  basis,
the  Parties'  Capital Accounts shall be debited or credited  for
items   of  depreciation,  cost  recovery,  Simulated  Depletion,
amortization  and  gain  or  loss (including  Simulated  Gain  or
Simulated  Loss)  with respect to such property computed  in  the
same  manner as such items would be computed if the adjusted  tax
basis of such property were equal to such book value, in lieu  of
the  capital  account adjustments provided above for such  items,
all in accordance with Regulation Section 1.704-1(b)(2)(iv)(g).

      (f)   It  is the intention of the Parties that the  Capital
Accounts  of  each  Party be kept in the  manner  required  under
Regulation   Section  1.704-1(b)(2)(iv).   To  the   extent   any
additional adjustment to the Capital Accounts is required by such
regulations,  CWEI is hereby authorized to make  such  adjustment
after notice to the Party.

                       [End of Exhibit D]
