<PAGE>



quantities  of  Hydrocarbons  which can be expected,  with little  doubt,  to be
recoverable  commercially at current prices and costs, under existing regulatory
practices  and with  existing  conventional  equipment  and  operating  methods.
Depending  upon their  status of  development,  such  proved  reserves  shall be
subdivided   into  the   following   classifications   and  have  the  following
definitions:

              (a) "Proved  Developed  Reserves" shall mean proved reserves which
        can be expected to be recovered  through  existing  wells with  existing
        equipment and operating methods. This classification shall include:

                    (1) "Proved Developed  Producing  Reserves" which are proved
              developed reserves which are expected to be produced from existing
              wells; and

                    (2)  "Proved  Developed  Nonproducing  Reserves"  which  are
              proved  developed  reserves  which  exist  behind  the  casing  of
              existing  wells,  or at minor depths  below the present  bottom of
              such wells,  which are expected to be produced through these wells
              in the predictable  future,  where the cost of making Hydrocarbons
              available for  production  should be relatively  small compared to
              the cost of a new well.

              Additional  Hydrocarbons  expected  to  be  obtained  through  the
        application  of improved  recovery  techniques  are  included as "Proved
        Developed  Reserves"  only after testing by a pilot project or after the
        operation  of an  installed  program has  confirmed  through  production
        responses that increased recovery will be achieved.

              (b) "Proved  Undeveloped  Reserves"  shall mean all reserves which
        are expected to be recovered from new wells on undrilled acreage or from
        existing  wells where a  relatively  major  expenditure  is required for
        recompletion.  Such  reserves on undrilled  acreage are limited to those
        drilling units offsetting  productive units which are reasonably certain
        of production  when drilled.  Proved  reserves for other undrilled units
        are claimed only where it can be demonstrated with reasonable certainty,
        based on accepted  geological,  geophysical and engineering  studies and
        data, that there is continuity of production from an existing productive

provisions of this Agreement,  shall have the full and exclusive right to manage
and control the business and affairs of the Production  Partnership  and to make
all decisions  regarding the business of the  Production  Partnership  and shall
have all of the rights, powers and obligations of managing general partners of a
general  partnership  under the laws of the State.  The Managing  Partners shall

with  respect  to  the  acquisition  of  Producing  Properties  whose  aggregate
acquisition price,  together with the anticipated aggregate acquisition price of
Producing  Properties  subject to such purchase options,  is in excess of 20% of
the Limited Partnership's Capital Contribution, and (b) no single acquisition of
Producing Properties by Geodyne Production pursuant to this proviso shall exceed
10% of the Limited Partners' capital  contributions to the Limited  Partnership;

transfer of any Producing Property that constitutes a significant portion of the
assets of the Production  Partnership;  and (vi) the determination not to extend
the term of the  Production  Partnership  as set  forth in  Section  2.4 of this
Agreement.  The  Management  Committee  shall  have the  power to  delegate  its
management  authority  with  respect to any  "significant"  action to a Managing
Partner  at such  times and under  such  conditions  as it may decide in its own
discretion.

        The Managing Partners' management authority respecting all other actions
which are in the ordinary course of the Production  Partnership's operations may
be exercised by either  Managing  Partner  without the  concurrence of the other
Managing Partner,  provided that the Managing Partner exercising such management
authority  shall,  upon  inquiry  by the  other  Managing  Partner,  notify  the
inquiring  Managing Partner of the nature of such actions undertaken without the
concurrence of the inquiring  Managing Partner.  The Management  Committee shall
have the authority (i) to determine  that the  "significant"  actions  specified
herein shall no longer be "significant" actions for the purposes of this Section
4.1C and to amend this Agreement  pursuant to Section l0.1A of this Agreement to
reflect  such  determination,  and  (ii) to  determine  which  other  Production
Partnership  operations,  other than those specified  herein,  are "significant"
actions for purposes of this Section 4.1C.

      Affiliates' insurance, at the Production Partnership's expense, to protect
      the  Production  Partnership  Property and the business of the  Production
      Partnership  against loss,  and to protect the Managing  Partners  against
      liability  to  third  parties   arising  out  of  Production   Partnership
      activities,  such  insurance to be in such  limits,  to be subject to such
      deductibles  and to  cover  such  risks  as  the  Managing  Partners  deem
      appropriate;

            (xxii) pay all ad  valorem  taxes  levied or  assessed  against  the
      Production  Partnership  Properties,  all taxes  upon or  measured  by the

      income taxes) directly  related to operations  conducted by the Production
      Partnership;

            (xxiii)  enter  into   agreements   on  behalf  of  the   Production
      Partnership  with  Affiliates  subject  to the  limitations  set  forth in
      Section 4.3B of this Agreement;

            (xxiv) sell all or  substantially  all of the  properties  and other

      Partnership  consideration consisting of cash, securities,  other property
      or any other form of consideration,  or any combination  thereof,  at such
      prices  and for  such  forms  of  consideration  as they  deem in the best
      interests of the Limited Partners;  provided,  however,  that no such sale
      shall be consummated  without the prior Consent of the Limited Partnership
      pursuant to the provisions of Section 4.4B of this Agreement. In the event
      of the dissolution of the Production Partnership followed by any such sale
      of the  Production  Partnership's  assets,  the Managing  Partners  shall,

      the  commencement  of a  partnership  level  audit or a final  partnership
      administrative  judgment,  and Geodyne Production shall perform all duties

      B. Reliance by Third Parties on Managing Partners'  Authority.  No person,
firm or corporation dealing with the Production Partnership shall be required to
inquire  into the  authority  of the  Managing  Partners to take or refrain from

inquiring shall be entitled to rely upon a certificate of the Managing  Partners
as to their due authorization.

      Section 4.3.  Sales, Purchases and Operation of Producing Properties;
                    Additional Financing
      ---------------------------------------------------------------------

      A. Except with respect to Producing  Properties  whose aggregate  purchase
price does not exceed 10% of the Limited Partners' capital  contributions to the
Limited  Partnership,  no Producing Property shall be acquired by the Production
Partnership  unless there has been prepared and evaluated  with respect  thereto
either an Acquisition  Reserve Report or an Engineering  Audit Letter acceptable
to the Management Committee;



                                      -26-
<PAGE>




      B. Neither the Managing Partners nor any Affiliate shall sell, transfer or
convey any or all of their  interest in Producing  Properties to the  Production
Partnership  or purchase or acquire any oil and gas  properties or interest from
the  Production  Partnership,   directly  or  indirectly,   except  pursuant  to
transactions  that are fair and reasonable to the Limited  Partnership under the
circumstances  at the time such  transaction is consummated.  Such  transactions
shall be further subject to the following restrictions:

            (i)  Prior to the  date on  which  the  Production  Partnership  has
      acquired its final Producing  Property,  neither the Managing Partners nor
      any Affiliate of a Managing  Partner  (other than an  Affiliated  Program)
      shall  acquire  any  Producing   Property  after  the  Activation  of  the
      Production  Partnership  unless prior thereto the  Production  Partnership
      shall have been offered the right to acquire such Producing  Property,  or
      an interest  therein,  and the Management  Committee shall have determined
      that the acquisition of such Producing  Property,  or an interest therein,
      is not in the best interests of the Production Partnership;

            (ii)  Any  purchase  or sale of a  Producing  Property  from or to a
      Managing   Partner  or  any  Affiliate  shall  be  made  at  the  Property
      Acquisition  Cost for such Producing  Property as adjusted for intervening
      operations,  unless the Managing  Partner or such Affiliate has reasonable
      grounds  to  believe  that cost is  materially  more or less than the fair
      market value of such  property,  in which case such sale or purchase shall
      be made at a price equal to the fair market value thereof as determined by
      an independent petroleum engineer;

            (iii) If a Managing Partner sells, transfers or conveys any oil, gas
      or other mineral interests or property to the Production  Partnership,  it
      must,  at the  same  time,  sell to the  Production  Partnership  an equal
      proportionate  interest in all its other property in the same Prospect.  A
      Sale or conveyance to the  Production  Partnership of less than the entire
      ownership  interest  of a  Managing  Partner  or  any  Affiliate  is  only
      permitted  if: (a) the  interests  retained or  obtained  by the  Managing
      Partners or  Affiliate  and  acquired by the  Production  Partnership  are
      either (x)  proportionate,  uniform and undivided Working Interests if the
      Producing Property



                                      -27-
<PAGE>



      acquired  by the  Production  Partnership  is a  Working  Interest  or (y)
      proportionate,  uniform and undivided  Royalty  Interests if the Producing
      Property  acquired by the  Production  Partnership  is a Royalty,  (b) the
      respective  obligations  of the  Managing  Partners or  Affiliate  and the
      Production Partnership are substantially the same, and (c) the interest of
      the Managing  Partners or their Affiliates in revenues does not exceed the
      amount  proportionate to their interest.  The Managing  Partners and their
      Affiliates  may not retain or obtain any overrides or other burdens on the
      interest  obtained by the Production  Partnership,  and may not enter into
      any  Farmouts  with  respect  to  their  retained   interest,   except  to
      nonaffiliated third parties or to an Affiliated Program;

            (iv) In the event a Managing  Partner or any  Affiliate  proposes to
      acquire  an  interest  in a  Producing  Property  in which the  Production
      Partnership  has an interest or in a Producing  Property  abandoned by the
      Production   Partnership   within  one  year   preceding   such   proposed
      acquisition,  such Managing  Partner or Affiliate shall offer the interest
      to the Production  Partnership;  and if cash or financing is not available
      to the  Production  Partnership  to purchase such  interest,  neither such
      Managing Partner nor Affiliate shall acquire an interest in such Producing
      Property.  The term "abandon" for the purpose of this  subparagraph  shall
      mean the  termination,  either  voluntary  or by operation of the Lease or
      otherwise,  of  all  of  the  Production  Partnership's  interest  in  the
      Producing  Property.  This  subsection  shall not apply after the lapse of
      five  years of the  Activation  of the  Production  Partnership  or to any
      Affiliated  Program  where the interest of such  Managing  Partner is less
      than or equal to its interest in the Production Partnership,  there are no
      duplication of fees to the Managing Partners, and the Managing Partners do
      not  obtain  a  greater  benefit  from  purchase  of the  interest  by the
      Affiliated  Program than they would if the interest were  purchased by the
      Production Partnership;

            (v) During the existence of the Production Partnership and before it
      has  ceased  operations,   neither  Managing  Partner  nor  any  Affiliate
      (excluding  any  Affiliated  Program  where the interest of such  Managing
      Partner  is  less  than  or  equal  to  its  interest  in  the  Production
      Partnership)  shall  acquire,  retain or drill for its own account any oil
      and gas interest in any Prospect



                                      -28-
<PAGE>



      upon which the Production  Partnership  possesses an interest,  except for
      transactions which comply with Section 4.3B(iii) or 4.8 of this Agreement.
      The  geological  limits of a Producing  Property  owned by the  Production
      Partnership  shall be enlarged or contracted on the basis of  subsequently
      acquired  geological  data to define the productive  limits of a reservoir
      and must include all of the acreage  determined by the subsequent  data to
      be encompassed by such reservoir.  If the geological limits of a Producing
      Property, as so enlarged, encompass any interest held by either a Managing
      Partner or an Affiliate of a Managing  Partner  (excluding  an  Affiliated
      Program  where the  interest of such  Managing  Partner is identical to or
      less than its interest in the Production Partnership), such interest shall
      be sold to the Production Partnership in accordance with the provisions of
      Section 4.3B(iv) of this Agreement and any net income previously  received
      by the Managing  Partner or Affiliate shall be paid over to the Production
      Partnership.   If  a  Managing  Partner  acquires  additional  acreage  or
      interests in a Prospect of the Production  Partnership,  it must sell such
      to the Production  Partnership  and is prohibited  from retaining any such
      interest,  except as may be permitted  by Section 4.3B of this  Agreement.
      Notwithstanding  the  foregoing,  the Production  Partnership  will not be
      required to expend  additional  funds to acquire any such interest  unless
      funds are available from the Capital Contributions of the Partners;

            (vi)  Producing  Properties  may be sold,  Farmed-out  or  otherwise
      transferred from or to an Affiliated Program only pursuant to transactions
      that (a) comply with Sections  4.3B(iii)  and 4.3B(iv) of this  Agreement,
      and (b)  are in  exchange  for  the  transferee's  obligation  to  conduct
      exploratory  drilling,   Development  Drilling,   Identified   Development
      Drilling  or  Improved  Recovery  operations  on  such  properties  or  in
      connection  with the  formation of a joint  venture  among the  Production
      Partnership and such Affiliated  Program,  provided that the  compensation
      arrangement or any other interest or right of the Managing Partners or any
      Affiliate  is  the  same  in the  Production  Partnership  and  Affiliated
      Program,  or, if  different,  the aggregate  compensation  of the Managing
      Partners  does not  exceed the lower of the  compensation  they would have
      received in the Production  Partnership or the Affiliated Program, and the
      terms of such Sale,  Farmout or  transfer  comply with the  provisions  of
      Section 4.8 of this Agreement;



                                      -29-
<PAGE>



            (vii) Any Sale of  inventory or other  materials  by the  Production
      Partnership  to any  Managing  Partner or  Affiliate  shall be made at the
      applicable  rates  set  forth  in the  standard  form  of  the  accounting
      procedure  then  recommended  by  the  Council  of  Petroleum  Accountants
      Societies of North America;

            (viii)  Any  operating  agreements  pursuant  to which any  Managing
      Partner or any Affiliate acts as operator of Producing Properties shall be
      of a nature customary in the industry and payments to any Managing Partner
      or any Affiliate for acting as operator shall not exceed the  compensation
      which would be paid by  unaffiliated  third parties in the same geographic
      area  for  similar  goods  and  services.  Reimbursement  of the  Managing
      Partner's  overhead  pursuant  to such  operating  agreement  will  not be
      duplicative of any reimbursement of General and Administrative  Costs made
      pursuant to Section 5.2 of this Agreement; and

            (ix) To the extent a Managing  Partner or any Affiliate  acquires an
      interest  in a  Producing  Property  in which the  Production  Partnership
      acquires an interest,  such  Managing  Partner or Affiliate  shall pay its
      allocable  portion  of the  cost  of the  preparation  of the  Acquisition
      Reserve Report or Engineering Audit Letter, as the case may be, respecting
      such Producing Property.

      C.  The  Managing  Partners  may  not  expend  any  amount  of  Production
Partnership funds over the term of the Production Partnership for the payment of
Production  Partnership  costs  (other  than  recompletion  costs)  incurred  in
connection  with  Development  Drilling and Identified  Development  Drilling in
excess of 10% of the amount of the Limited  Partners'  capital  contributions to
the  Limited  Partnership  and the  Production  Partnership  borrowings.  If the
Managing Partners determine that funds in addition to the Capital  Contributions
to the  Production  Partnership  are  required  for the  payment  of  Production
Partnership costs (other than Property Acquisition Costs), the Managing Partners
may apply or  reserve  Income  or  Investment  Income  for the  payment  of such
Production  Partnership  costs  and/or  the  Managing  Partners  may  cause  the
Production Partnership to borrow funds for the payment of Production Partnership
costs incurred in connection with Development




                                      -30-
<PAGE>




Drilling,  Identified  Development  Drilling and Improved  Recovery  operations;
provided,  however,  that the  aggregate  outstanding  principal  amount of such
borrowings  shall  not at any one  time  exceed  an  amount  equal to 20% of the
Limited Partners' capital contributions to the Limited Partnership.

        D. Each Managing  Partner shall have the authority to secure the payment
of  borrowings  incurred by it for its own account or for purposes of paying its
allocable share of Production  Partnership  costs by assigning to lenders all or
part of its Managing Partner's  interest in Profits and Distributable  Cash, and
by  granting  such  lenders a security  interest  or  mortgage  in an  undivided
interest  in any  Production  Partnership  Property  not to exceed its  Managing
Partner's percentage interest in Income;  provided,  however,  that the Managing
Partners, in the aggregate,  shall retain unencumbered at least a 1% interest in
each  of  Production  Partnership  Property,  Profits  and  Distributable  Cash.
Notwithstanding  anything to the contrary in this Agreement, in the event of any
sale or  foreclosure  of a  Managing  Partner's  interest  in  full  or  partial
satisfaction of such borrowings,  appropriate  adjustments  shall be made in the
Capital Accounts of the Partners and in the method by which Income and costs are
allocated to the Partners to assure that the Limited  Partnership  and the other
Managing  Partner  will not bear any of the costs  attributable  to such sold or
foreclosed interest and that such Managing Partner will not share or participate
in any of the capital, Income, costs or distributions  attributable to such sold
or  foreclosed  interest  except  to the  extent  of the  unencumbered  interest
retained by such Managing Partner.

       Section 4.4.  Prohibited Transactions
       -------------------------------------

      A.  Notwithstanding any other provision of this Agreement to the contrary,
the following transactions are expressly prohibited:

            (i) the  Production  Partnership  shall  not  make  any  loans  to a
      Managing Partner or any Affiliate;

              (ii) neither the Managing  Partners nor any  Affiliate  shall make
      any loans to the Production  Partnership  except at a rate of interest not
      in excess of the  interest  cost  incurred  by the  Managing  Partners  or
      Affiliates  or the  amount  of  interest  that  would  be  charged  to the
      Production Partnership (without regard to the Managing Partner's or




                                      -31-
<PAGE>




      Affiliate's  financial  abilities or  guarantees)  by  unrelated  banks on
      comparable  loans  for the  same  purpose,  whichever  is  lower,  and the
      Managing  Partners and  Affiliates  shall not receive  points or financing
      charges or fees regardless of the amount;

              (iii) except as expressly contemplated hereby, no agent, attorney,
      accountant  or other  independent  consultant  or  contractor  who is also
      employed on a full-time  basis by any  Managing  Partner or any  Affiliate
      shall  be  compensated  by  the  Production  Partnership  for  his  or her
      services;

              (iv) other than those  received for the account of the  Production
      Partnership,  no rebates may be received  by any  Managing  Partner or any
      Affiliate  in  connection  with  Production   Partnership   operations  or
      expenditures, nor may any Managing Partner or any Affiliate participate in
      any  reciprocal  business  arrangement  that would  circumvent  any of the
      provisions of this Agreement;

              (v) on a monthly  basis,  costs paid and  revenues  received  by a
      Managing  Partner  or an  Affiliate  for  the  account  of the  Production
      Partnership  shall be determined  and the net amount  resulting  from such
      monthly  settlement  shall  be  deposited  into a  Production  Partnership
      Account and no funds which, after such monthly settlement,  are determined
      to be held for the account of the Production  Partnership shall be kept in
      any account other than a Production  Partnership Account, and the Managing
      Partners  shall not  employ,  or permit any other  Person to employ,  such
      funds in any manner except for the benefit of the Production  Partnership;
      it being  understood  that the  Managing  Partners  may invest  Production
      Partnership  funds temporarily in the investments set forth in Section 9.3
      of this Agreement pending their use by the Production  Partnership.  After
      such  monthly  settlement,   Production   Partnership  funds  may  not  be
      commingled  with separate  funds of either  Managing  Partner or any other
      entity; and

              (vi) the Limited Partnership shall not make any advance payment to
      the  Managing  Partners or their  Affiliates,  except  where  necessary to
      secure tax benefits of prepaid drilling costs.

      B.  Notwithstanding any other provision of this Agreement to the contrary,
without the prior  Consent of the Limited  Partnership  granted  pursuant to the
provisions of Article Eleven of this Agreement and the provisions of the Limited
Partnership Agreement, the Managing Partners shall not:

            (i)  lease,  sell,  or dispose  of all or  substantially  all of the
      Production Partnership's assets;

            (ii)  make,  exercise  or deliver  any  general  assignment  for the
      benefit of the Production Partnership's creditors;

            (iii) except as set forth in Section  l0.1A,  amend any provision of
      this Agreement; or

            (iv) dissolve the Production Partnership.

      Section 4.5.  Other Agreements of the Managing Partners
      -------------------------------------------------------

      A.  Anything in this  Agreement  to the  contrary  notwithstanding,  it is
agreed that:

              (i) the Managing  Partners and their Affiliates shall not take any
      action  with  respect  to  the  assets  or  property  of  the   Production
      Partnership which does not benefit exclusively the Production Partnership,
      including:

                  (a)  the  utilization  of  Production   Partnership  funds  as
            compensating balances for the benefit of the Managing Partners or an
            Affiliate of a Managing Partner; and

                  (b) the commitment of future production;

              (ii)  all   benefits   from   marketing   arrangements   or  other
      relationships  affecting property of any Managing Partner or its Affiliate
      and the Production  Partnership shall be fairly and equitably  apportioned
      according to the respective interests of each;

            (iii) the  Managing  Partners may never  profit  themselves  nor any
      Affiliate by  Development  Drilling,  Identified  Development  Drilling or
      Improved   Recovery   operations  in   contravention  of  their  fiduciary
      obligation to the Limited Partnership; and




                                      -33-
<PAGE>





              (iv) neither the Managing  Partners nor any Affiliate shall render
      to the Production Partnership any oil field, equipage or drilling services
      nor sell or lease to the Production  Partnership  any equipment or related
      supplies unless:

                  (a) such Person is engaged,  independently  of the  Production
            Partnership and as an ordinary and ongoing business, in the business
            of rendering  such services or selling or leasing such equipment and
            supplies to a substantial extent to other Persons in the oil and gas
            industry in addition to drilling  and income  programs in which such
            Person has an interest;

                  (b) the compensation,  price or rental therefor is competitive
            with the compensation,  price or rental of other Persons in the area
            engaged in the business of rendering  comparable services or selling
            or leasing comparable  equipment and supplies which could reasonably
            be made available to the Production Partnership;

                  (c)   the drilling  services  are billed on either a per foot,
            per day or per hour rate, or some combination thereof; and

                  (d) provided that, if such Person is not engaged in a business
            within the meaning of subdivision (a), then such compensation, price
            or rental shall be the cost of such services,  equipment or supplies
            to such  Person or the  competitive  rate which could be obtained in
            the area, whichever is less.

      Section 4.6.  Construction of Gas Gathering Lines
      -------------------------------------------------

      The Managing  Partners may cause the  Production  Partnership to construct
gas  gathering  lines if, in the opinion of the Managing  Partners,  it would be
economically  feasible and otherwise  consistent with prudent operating practice
to do so. The costs of any such  gathering  lines will be deemed to be Operating
Costs and shall be charged to the accounts of the Partners as such. The Managing
Partners  may,  in their  discretion,  construct,  or cause  an  Affiliate  of a
Managing  Partner or other person to construct,  gathering lines from Production
Partnership Wells to gas transmission systems.

<PAGE>




Whenever the Managing  Partners  construct,  or cause an Affiliate of a Managing
Partner to construct,  a gathering line from a Production  Partnership Well to a
gas  transmission  system,  the  Production  Partnership  shall pay the Managing
Partners or such  Affiliate an amount that is not greater than the  compensation
that an  unrelated  party  could  have  reasonably  charged  in an  arm's-length
transaction  for  similar  services  in the area as a  transmission  fee for the
transmission  of all gas through the  gathering  system so  constructed,  and no
other  transmission  fee  shall  be  paid  to the  Managing  Partners  or to any
Affiliate.

      Section 4.7.  Contracts with the Managing Partners and Affiliates
      -----------------------------------------------------------------

      All services provided to the Production  Partnership by a Managing Partner
or any  Affiliate  for which it is  compensated  shall be  embodied in a written
contract   precisely   setting  forth  the  services  to  be  rendered  and  the
compensation  to be paid.  Each contract  relating to a transaction  between the
Production Partnership and any Managing Partner or any Affiliate shall contain a
provision  which shall  permit  termination  of the  contract by the  Production
Partnership  without  penalty on 30 days'  prior  written  notice.  The  Limited
Partnership  shall have the power to terminate,  without  cause or penalty,  any
such contract on behalf of the Production Partnership.

       Section 4.8.  Farmouts
       ----------------------

      The  Management  Committee may dispose of Producing  Properties by Sale or
Farmout  when the  Management  Committee,  exercising  the standard of a prudent
operator,  determines that (a) the Production Partnership lacks sufficient funds
to conduct Development  Drilling,  Identified  Development  Drilling or Improved
Recovery  operations on the  properties and cannot obtain  suitable  alternative
financing for such  Development  Drilling,  Identified  Development  Drilling or
Improved Recovery operations;  (b) the properties have been downgraded by events
occurring  after  assignment  to the  Production  Partnership  to the point that
additional  Development  Drilling,  Identified  Development  Drilling,  Improved
Recovery operations or continued  production would no longer be desirable to the
Production  Partnership;   (c)  Development  Drilling,   Identified  Development
Drilling or Improved  Recovery  operations on the properties  would result in an
excessive concentration of Production Partnership funds on a



                                      -35-
<PAGE>



Producing Property creating, in the opinion of the Management  Committee,  undue
risk to the Production Partnership;  or (d) the best interests of the Production
Partnership would be served by the Sale or Farmout.  The Production  Partnership
shall not conduct any  drilling of wells  other than  Development  Drilling  and
Identified Development Drilling;  provided,  however, that the drilling of wells
other than  Development  Drilling  and  Identified  Development  Drilling may be
performed on behalf of the Production Partnership pursuant to Farmouts.  Neither
the Managing  Partners nor any  Affiliate  shall enter into any Farmout or other
agreement with the Production Partnership where in consideration for services to
be rendered,  an interest in production  is payable to the Managing  Partners or
any Affiliate,  unless the  Production  Partnership  has previously  expended or
committed to expend the maximum amount that is authorized to use for Development
Drilling  or  Identified  Development  Drilling.  Any Sale,  Farmout  or similar
agreement between the Production  Partnership and a Managing Partner,  Affiliate
or Affiliated Program will be permitted under the restrictions set forth in this
Article Four and will be subject to the following conditions:

               (i)  the  Management   Committee  (or  a  Managing  Partner,   if
      management  authority of the Production  Partnership  with respect thereto
      has been  delegated  to it by the  Management  Committee)  exercising  the
      standard of a prudent operator,  shall determine that the Sale, Farmout or
      similar agreement is in the best interests of the Production  Partnership;
      and

              (ii) the terms of the  Sale,  Farmout  or  similar  agreement  are
      consistent  with and in any case no less  favorable than those utilized in
      the same geographic area for similar arrangements.

      Section 4.9.  Other Operations
      ------------------------------

      The Managing Partners and the Management  Committee shall devote such time
to  the  Production  Partnership  as is  reasonably  required  to  carry  on the
Production  Partnership  business,  and the  Managing  Partners,  members of the
Management Committee and their Affiliates shall at all times be free, subject to
any restrictions  contained herein, to engage in all aspects of the Hydrocarbons
and natural  resources  business  for their own accounts and for the accounts of
others. Without limiting the generality of the foregoing,  the Managing Partners
and their Affiliates shall have the right to organize and operate other




                                      -36-
<PAGE>




partnerships, joint ventures or other oil and gas investment programs similar to
the Limited Partnership and the Production Partnership.

      Section 4.10.  Prosecution, Defense and Settlement of Claims;
                     Indemnification
      -------------------------------------------------------------

      A. The Managing  Partners  shall arrange to prosecute,  defend,  settle or
compromise  actions  at  law  or in  equity  at the  expense  of the  Production
Partnership  as may be  necessary  to enforce or protect  the  interests  of the
Production  Partnership.  The  Managing  Partners  shall  satisfy any  judgment,
decree,  decision or settlement,  first, out of any insurance proceeds available
therefor,  next,  out of the  Production  Partnership  assets and  Income,  and,
finally,  out of the assets of the Managing Partners and the general partners of
the Limited Partnership.

      B. In any threatened,  pending or completed action,  suit or proceeding to
which the Managing  Partners are a party or are threatened to be made a party by
reason  of the  fact  that  they are the  Managing  Partners  of the  Production
Partnership  (other  than  an  action  by or in  the  right  of  the  Production
Partnership)  involving an alleged cause of action for damages  arising from the
performance of their duties under this Agreement or other activities relative to
the management and  disposition of Producing  Properties or production from such
properties,  the Production  Partnership  shall indemnify the Managing  Partners
against  expenses,  including  attorneys'  fees,  judgments  and amounts paid in
settlement,  actually and  reasonably  incurred by them in connection  with such
action,  suit or  proceeding  if they acted in good  faith and in a manner  they
reasonably  believed to be in the best interests of the Production  Partnership,
and provided that their conduct does not  constitute  negligence or  misconduct.
The  termination  of any  action,  suit or  proceeding  by  judgment,  order  or
settlement shall not of itself create a presumption  that the Managing  Partners
did not act in good faith and in a manner which they  reasonably  believed to be
in the best interests of the Production Partnership.

      C. In any  threatened,  pending or  completed  action or suit by or in the
right of the Production Partnership,  to which the Managing Partners are a party
or are  threatened  to be made a party,  involving an alleged cause of action by
the Limited Partnership for damages arising from the activities of the




                                      -37-
<PAGE>




Managing  Partners in the  management of the internal  affairs of the Production
Partnership  as prescribed in this  Agreement or by law, or both, the Production
Partnership shall indemnify the Managing  Partners against  expenses,  including
attorneys' fees, actually and reasonably incurred by them in connection with the
defense or  settlement of such action or suit if they acted in good faith and in
a manner they reasonably  believed to be in the best interests of the Production
Partnership  as specified  in this  subsection,  except that no  indemnification
shall be made in respect of any claim,  issue or matter as to which the Managing
Partners' course of conduct constituted negligence or misconduct.

      D. To the extent that a Managing Partner has been successful on the merits
or  otherwise  in defense  of any  action,  suit or  proceeding  referred  to in
Sections 4.l0B or 4.l0C of this Agreement,  or in defense of any claim, issue or
matter  therein,  the  Production  Partnership  shall  indemnify  it against the
expenses,  including  attorneys' fees, actually and reasonably incurred by it in
connection therewith.

      E. Any  indemnification  under Section 4.l0B and 4.10C of this  Agreement,
unless ordered by a court,  shall be made by the Production  Partnership only as
authorized in the specific  case and only upon a  determination  by  independent
legal counsel in a written  opinion that such  indemnification  is proper in the
circumstances  because the indemnified party has met the applicable  standard of
conduct set forth in Sections 4.l0B or 4.l0C of this Agreement.

      F. The Production Partnership shall not incur the costs of that portion of
insurance which insures the Managing  Partners for any liability as to which the
Managing Partners are prohibited from being indemnified under Section 4.10.

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

      Section 5.1.  Distributions of Production Partnership Funds
      -----------------------------------------------------------

      The Distributable Cash of the Production  Partnership shall be distributed
simultaneously  to the Limited  Partnership and the Managing  Partners within 45
days after the close of each calendar quarter. Each Partner's share of each such



                               -38-
<PAGE>




distribution of  Distributable  Cash shall be determined  after giving effect to
the  allocations  set forth in Sections 5.3 and 5.4 of this  Agreement  for such
period. All distributions of Distributable  Cash shall reduce  dollar-for-dollar
the balances of the Partners' Capital Accounts.

      Section 5.2.  Fees and Reimbursement of Expenses to the Managing Partners
      -------------------------------------------------------------------------

      Geodyne  Production and PW Production  shall receive as Managing  Partners
(1) on a nonrecurring  basis, the Management Fee in an amount equal to 1-1/2% of
the Limited Partners' capital contributions to the Limited Partnership;  and (2)
reimbursement  for Direct  Administrative  Costs billed directly to the Managing
Partners and General and Administrative  Costs incurred by the Managing Partners
or their  Affiliates  allocable  to the  Production  Partnership,  except to the
extent that the Managing  Partners or their Affiliates are otherwise  reimbursed
for such costs  through  the payment of Property  Acquisition  Costs,  Operating
Costs or otherwise.  Geodyne Production and PW Production shall allocate between
themselves the payment of the  Management  Fee as follows:  in the event the Fee
(as defined in the Limited Partnership  Agreement)  (hereinafter  referred to as
the "Limited Partnership Fee") is less than the actual organization and offering
costs of the  Limited  Partnership  plus  Unreimbursed  Prior  Organization  and
Offering  Costs (as  defined in the  Limited  Partnership  Agreement),  then the
Management Fee shall be paid 60% to PW Production and 40% to Geodyne  Production
to the  extent  of such  deficiency,  60% to PW  Production  and 40% to  Geodyne
Production to the extent of organization and offering costs and the remainder of
the  Management  Fee  shall  be paid  75% to PW  Production  and 25% to  Geodyne
Production. In the event the Limited Partnership Fee is equal to or greater than
the actual  organization  and  offering  costs of the Limited  Partnership  plus
Unreimbursed  Prior  Organization  and Offering Costs (as defined in the Limited
Partnership  Agreement),  then  the  Management  Fee  shall  be  paid  60% to PW
Production  and 40% to  Geodyne  Production  to the extent of  organization  and
offering  costs and the  remainder  shall be paid as  follows:  in the event the
payment referred to in Section 3.6B(i) of the Limited Partnership  Agreement has
been made (but the payments in Section 3.6B(ii) and (iii) have not been made) to
the general  partners of the Limited  Partnership,  the  Management Fee shall be
paid 75% to PW  Production  and 25% to  Geodyne  Production;  in the  event  the
payment referred to in Section 3.6B(ii) of the Limited



                                      -39-

Partnership  Agreement  has been made (but the payment in Section  3.6B(iii) has
not been made) to the general partners of the Limited Partnership, the excess of
the Management  Fee over the amount paid to the general  partners of the Limited
Partnership  pursuant to Section 3.6B(ii) of the Limited  Partnership  Agreement
shall be paid 75% to PW Production and 25% to Geodyne Production, the balance of
the  Management  Fee, but not in excess of 1% of the Limited  Partners'  capital
contributions to the Limited Partnership, shall be paid 50% to PW Production and
50% to Geodyne Production, and any remaining balance of the Management Fee shall
be paid 70% to PW Production and 30% to Geodyne Production; and in the event the
payment referred to in Section  3.6B(iii) of the Limited  Partnership  Agreement
has been made to the general partners of the Limited Partnership,  the excess of
the Management  Fee over the amount paid to the general  partners of the Limited
Partnership pursuant to Section 3.6B(iii) of the Limited Partnership  Agreement,
but not in excess of 1% of the Limited  Partners'  capital  contributions to the
Limited  Partnership,  shall be paid  50% to PW  Production  and 50% to  Geodyne
Production,  and the  balance  of the  Management  Fee  shall  be paid 70% to PW
Production and 30% to Geodyne Production.

      Section 5.3.  Allocation of Income, Investment Income, Costs and
                    Deductions
      ----------------------------------------------------------------

      A. The Income,  Investment Income,  Profits,  Production Partnership costs
and losses of the Production  Partnership shall be determined and allocated with
respect to each Fiscal Year of the  Production  Partnership  as of and within 75
days after the end of such Fiscal Year.

      B.  (i) 100% of  Investment  Income,  Property  Acquisition  Costs,  costs
      incurred in connection with Identified Development Drilling (including any
      interest,  commitment  fees and other  finance  charges  with  respect  to
      borrowings  incurred  in  connection  therewith)  and the  Management  Fee
      referred to in Section 5.2(1) of this Agreement shall all be allocated to,
      and borne by, the Limited  Partnership.  100% of Organization and Offering
      Costs  shall be  allocated  to, and borne by,  the  Managing  Partners  as
      follows:  60% to PW Production  and 40% to Geodyne  Production.  Except as
      otherwise provided in Sections 5.3B(ii) and 5.3B(iii), Income, General and
      Administrative  Costs,  Operating Costs, costs incurred in connection with
      Development Drilling and



                                      -40-
<PAGE>



      Direct  Administrative  Costs shall be allocated  among, and borne by, the
      Partners in the following percentages:

            (a)   Until Payout:
                  Limited Partnership             90.9091%

                  PW Production and Geodyne
                  Production (in the aggregate)    9.0909%


            (b)   After Payout:
                  Limited Partnership             85.8586%

                  PW Production and Geodyne
                  Production (in the aggregate)   14.1414%

      The Managing  Partners shall allocate  between  themselves their aggregate
      Interest before and after Payout as follows:  70% to PW Production and 30%
      to Geodyne  Production if the Production  Partnership is Activated  within
      twelve  months after the date on which the  registration  statement  filed
      with the Securities and Exchange  Commission  with respect to the Units is
      declared  effective (the "Effective  Date"),  and 60% to PW Production and
      40% to Geodyne  Production  if the  Production  Partnership  is  Activated
      during  the  twelve  month  period  ending  twenty-four  months  after the
      Effective Date; provided,  however, that if the Production Partnership was
      Activated  more  than  twelve  months  after  the  Effective  Date and the
      immediately  preceding  Prior  Production  Partnership  was  activated (as
      defined in the  partnership  agreement  respecting  such Prior  Production
      Partnership)  within  twelve  months  after the  Effective  Date,  then PW
      Production  shall be allocated that  percentage of the aggregate  Managing
      Partners'  Interest  represented by a fraction,  the numerator of which is
      equal  to the sum of (i) 70  multiplied  by the  number  of days  from the
      activation  of the  immediately  preceding  Prior  Production  Partnership
      through the date that is 12 months after the Effective  Date,  and (ii) 60
      multiplied by the number of days from the date that is 12 months after the
      Effective  Date  through  the  date of the  Activation  of the  Production
      Partnership, and the denominator of which is the total number of days that
      has  elapsed  from  the  activation  of the  immediately  preceding  Prior
      Production  Partnership to the  Activation of the Production  Partnership,
      and Geodyne  Production  shall be allocated  the balance of the  aggregate
      Managing Partners' Interest (such allocation



                                      -41-
<PAGE>



      between the  Managing  Partners of their  aggregate  Interest  being their
      "Sharing Ratios"). The Managing Partners shall have the authority to amend
      this Agreement to provide for any different  allocation between themselves
      at their discretion.

            (ii) As used in this  subsection,  the "Measuring Date" shall be the
      earlier  of the date on which  90% of the  Limited  Partnership's  Capital
      Contribution has been expended or the second anniversary of the Activation
      of the Production Partnership;  the first "Allocation Period" shall be the
      twelve  month  period  beginning  on the last day of the first full Fiscal
      Year  quarter  after the  Measuring  Date;  and each twelve  month  period
      following the end of the first Allocation Period shall also be referred to
      as an  "Allocation  Period".  Notwithstanding  anything  to  the  contrary
      contained herein,  if during each of the first two Allocation  Periods the
      amount of cash distributed to the Limited Partnership that is attributable
      to the  allocations  set forth in Section  5.3B(i) is less than a 15.1515%
      cumulative  (but  not  compounded)  twelve-month  return  on  the  Limited
      Partners'  capital  contributions to the Limited  Partnership,  then there
      shall be distributed to the Limited Partnership thereafter (in addition to
      the amount of Distributable  Cash  distributed to the Limited  Partnership
      resulting  from the  allocations to the Limited  Partnership  set forth in
      Section  5.3B(i))  an  amount  of  cash  up to 50% of the  cash  otherwise
      distributable  to  the  Managing  Partners   thereafter  pursuant  to  the
      allocations  set forth in Section  5.3B(i) not to exceed the amount of any
      such  deficiency (the amount of such cash  distribution  being a "Transfer
      Amount"),   and  Income  and  costs  sufficient  to  yield  an  amount  of
      Distributable Cash equal to the Transfer Amount and otherwise allocable to
      the  Managing  Partners  during the Fiscal  Year in which such  Allocation
      Period ends and,  to the extent  necessary,  each  Fiscal Year  thereafter
      pursuant to Section 5.3B(i) shall be allocated to the Limited Partnership.
      If during any Allocation Period after the initial two Allocation  Periods,
      the Limited  Partnership is being  allocated  Income and costs pursuant to
      Section 5.3B(i) such that there is distributed to the Limited  Partnership
      an amount of cash in excess of a 15.1515%  cumulative (but not compounded)
      twelve-month return on the Limited Partners' capital  contributions to the
      Limited  Partnership  since the  beginning  of the  first  two  Allocation
      Periods  (such excess amount of cash being the  "Surplus"),  and there has
      been distributed to the Limited Partnership a



                                      -42-
<PAGE>



      Transfer Amount,  then there shall be distributed to the Managing Partners
      thereafter  an aggregate  amount of cash  otherwise  distributable  to the
      Limited  Partnership  pursuant  to the  allocations  set forth in  Section
      5.3B(i)  equal to the  amount  of any  Surplus  (the  amount  of such cash
      distribution  being a  "Reverse  Transfer  Amount"),  and Income and costs
      sufficient to yield an amount of  Distributable  Cash equal to the Reverse
      Transfer Amount and otherwise  allocable to the Limited Partnership during
      the Fiscal  Year in which such  Allocation  Period ends and, to the extent
      necessary,  each Fiscal Year thereafter  pursuant to Section 5.3B(i) shall
      be allocated to the Managing Partners;  provided, however, that the amount
      of any Reverse Transfer Amount  distributed to the Managing Partners shall
      not  exceed an  amount  equal to the  aggregate  of the  Transfer  Amounts
      distributed to the Limited  Partnership  less the aggregate of all Reverse
      Transfer Amounts previously distributed to the Managing Partners.

            (iii) Notwithstanding  anything to the contrary contained herein, if
      on the seventh anniversary of the last day of the Fiscal Year in which the
      Production  Partnership  commences  Development  Drilling,  or  Identified
      Development  Drilling,  and  in  each  Fiscal  Year  thereafter,  (a)  the
      aggregate  amount  of Income  less the  aggregate  amount of direct  lease
      operating expenses and severance, ad valorem, windfall profits, excise and
      other taxes (but not income  taxes)  allocated to the Limited  Partnership
      pursuant to Section  5.3(B)(i)  attributable to production  resulting from
      Development  Drilling  and  Identified  Development  Drilling on Producing
      Properties is less than (b) the aggregate amount of costs allocated to the
      Limited  Partnership  pursuant to Section 5.3(B)(i) incurred in connection
      with Development Drilling and Identified Development Drilling on Producing
      Properties  during  each  Fiscal  Year  ending  seven or more years  prior
      thereto,  then  Income  and  costs  otherwise  allocable  to the  Managing
      Partners  pursuant to Section 5.3B(i) shall thereafter be allocated to the
      Limited Partnership until such deficiency in Income is eliminated.

            (iv) For purposes of the allocations  set forth in Section  5.3B(ii)
      of  this  Agreement,  the  amount  of  cash  distributed  to  the  Limited
      Partnership  for  purposes  of  determining  the  return  on  the  Limited
      Partners'  capital  contributions  to the  Limited  Partnership  shall not
      include any amounts attributable to the Production  Partnership's  payment
      of any windfall profits tax.




                                      -43-

      C. All items of Income,  gain,  loss,  deduction and credit  allowable for
Federal income tax purposes and all recapture of any such deductions and credits
shall be  allocated  and charged or credited to the  Partners in the same manner
that the revenues,  costs or expenses giving rise to such items of income, gain,
loss,  deduction  and credit  are  allocated  and  charged.  Federal  income tax
deductions  for cost or  percentage  depletion  with  respect  to any  Producing
Property shall be determined at the Partner level and shall be determined in the
case of  percentage  depletion  on the  same  basis  that  the  Income  from the
Producing Property is allocated;  and the Production Partnership shall allocate,
under Section  612A(c)(7)(D)  of the Code,  its adjusted basis in each Producing
Property to the Partners in proportion to the interest of each in the Production
Partnership capital ultimately used to acquire that property. If such allocation
of basis is not permitted  under the Code, the basis of each such property shall
be allocated in the manner  which the Managing  Partners  deem will most closely
achieve the result intended above.

      D. Capital  Accounts shall be established  and maintained for each Partner
in accordance with tax accounting  principles and with valid regulations  issued
by the U.S.  Treasury  Department under subsection  704(b) of the Code (the "704
Regulations").  To the  extent  that  tax  accounting  principles  and  the  704
Regulations  may conflict,  the latter shall  control.  In  connection  with the
establishment and maintenance of such Capital Accounts, the following provisions
shall apply:

            (1) Each  Partner's  Capital  Account  shall be (i) increased by the
      amount of its  Capital  Contribution,  the fair  market  value of property
      contributed  by it to  the  Production  Partnership  (net  of  liabilities
      securing such  contributed  property that the  Production  Partnership  is
      considered to assume or take subject to under section 752 of the Code) and
      allocations  to it of Income and gain (except to the extent such Income or
      gain has previously  been reflected in its Capital  Account by adjustments
      thereto)  and  (ii)  decreased  by  the  amount  of   Distributable   Cash
      distributed to it, the fair market value of property  distributed to it by
      the Production  Partnership (net of liabilities  securing such distributed
      property  that such  Partner is  considered  to assume or take  subject to
      under  section  752 of  the  Code)  and  allocations  to it of  Production
      Partnership  loss,  deduction (except to the extent such loss or deduction
      has previously been reflected



                                      -44-
<PAGE>



      in its Capital Account by adjustments thereto) and expenditures  described
      in section 705(a)(2)(B) of the Code.

            (ii) In the event Production  Partnership Property is distributed to
      a Partner, then, before the Capital Account of such Partner is adjusted as
      required by clause (i) of this Section 5.3D,  the Capital  Accounts of the
      Partners  shall be adjusted to reflect the manner in which the  unrealized
      Income,  gain, loss and deduction inherent in such Production  Partnership
      Property (that has not been reflected in such Capital Accounts previously)
      would be allocated among the Partners if there were a taxable  disposition
      of such Production  Partnership  Property for its fair market value on the
      date of distribution.

            (iii)  If,  pursuant  to  this  Agreement,   Production  Partnership
      Property is reflected on the books of the Production Partnership at a book
      value  that  differs  from  the  adjusted  tax  basis  of such  Production
      Partnership  Property,  then  the  Partners'  Capital  Accounts  shall  be
      adjusted in accordance  with the 704  Regulations  for  allocations to the
      Partners of depreciation,  depletion,  amortization,  and gain or loss, as
      computed for book purposes,  with respect to such  Production  Partnership
      Property.

            (iv) The Partner's  Capital Accounts shall be adjusted for depletion
      and gain or loss with respect to the Production  Partnership's  oil or gas
      properties  in whichever of the  following  manners the Managing  Partners
      determine is in the best interests of the Partners:

                  (a) The  Partners'  Capital  Accounts  shall be  reduced  by a
            simulated  depletion  allowance computed on each oil or gas property
            using either the cost depletion  method or the percentage  depletion
            method (without regard to the limitations under the Code which could
            apply to less than all Partners); provided, however, that the choice
            between  the cost  depletion  method  and the  percentage  depletion
            method  shall  be  made on a  property-by-property  basis  and  such
            choices  shall be binding  for all  Production  Partnership  taxable
            years  during  which  such  oil  or  gas  property  is  held  by the
            Production  Partnership.  Such  reductions  for  depletion  shall be
            allocated  among  the  Partners'   Capital   Accounts  in  the  same
            proportions as the adjusted basis in the particular property is



                                      -45-
<PAGE>



            allocated to each Partner. Upon the taxable disposition of an oil or
            gas  property  by  the   Production   Partnership,   the  Production
            Partnership's   simulated  gain  or  loss  shall  be  determined  by
            subtracting  its simulated  adjusted basis  (aggregate  adjusted tax
            basis of the Partners less simulated  depletion  allowances) in such
            property  from  the  amount  realized  on such  disposition  and the
            Partners'  Capital  Accounts  shall be increased or reduced,  as the
            case may be,  by the  amount of the  simulated  gain or loss on such
            disposition in proportion to the Partners'  allocable  shares of the
            total amount realized on such disposition, or

                  (b)  The  Production  Partnership  shall  reduce  the  Capital
            Account  of each  Partner  in an  amount  equal  to  such  Partner's
            depletion  allowance with respect to each oil or gas property of the
            Production  Partnership  (for the  Partner's  taxable year that ends
            within  the  Production   Partnership's   taxable  year),  but  such
            reductions  for  depletion  shall  not  exceed  the  adjusted  basis
            allocated to such Partner  with respect to such  property.  Upon the
            taxable  disposition  of an oil or gas  property  by the  Production
            Partnership, the Capital Account of each Partner shall be reduced or
            increased,  as the  case may be,  by the  amount  of the  difference
            between such Partner's  allocable share of the total amount realized
            on such disposition and such Partner's  remaining adjusted tax basis
            in such property.

            (v) For purposes of determining  the Capital  Account balance of any
      Partner  as of the end of any  Production  Partnership  taxable  year  for
      purposes of Subsection 5.3I hereto,  such Partner's  Capital Account shall
      be reduced by:

                  (a) Adjustments  that, as of the end of such year,  reasonably
            are expected to be made to such Partner's  Capital Account  pursuant
            to paragraph  (b)(2)(iv)(k)  of the 704  Regulations  for  depletion
            allowances  with respect to oil and gas properties of the Production
            Partnership, and



                                      -46-
<PAGE>



                  (b) Distributions that, as of the end of such year, reasonably
            are  expected to be made to such  Partner  pursuant to Code  section
            704(e)(2),  Code section 706(d), and paragraph (b)(2)(ii) of section
            1.751-1 of regulations promulgated under the Code, and

                  (c) Distributions that, as of the end of such year, reasonably
            are  expected  to be made to such  Partner to the extent they exceed
            offsetting   increases  to  such  Partner's   Capital  Account  that
            reasonably are expected to occur during (or prior to) the Production
            Partnership  taxable years in which such  distributions are expected
            to be made.

      E. The  Capital  Accounts  of those  Partners  which are  charged  with an
expense of the Production Partnership shall be credited with any portion of that
expense  which is finally  determined,  judicially  or  administratively,  to be
nondeductible  for  Federal  income  tax  purposes,  less  any  amortization  or
depreciation thereof incurred prior to the date that the credit is made.

      F. In  allocating  Income and costs for any Fiscal Year in which the ratio
for  sharing  Income  and  costs  changes  pursuant  to  Section  5.3B(i),   the
allocations  of Income and costs shall be made,  and the books of the Production
Partnership  shall be  closed,  as soon as  practicable  after  the date  Payout
occurs,  to determine  each Partner's  share of pre-change  Income and costs and
each Partner's share of post-change Income and costs for that Fiscal Year.

      G.  Proceeds  received from the Sale or transfer of all or any part of the
Production  Partnership's Producing Properties shall be allocated to the Limited
Partnership  and the Managing  Partners to the extent of their adjusted basis in
such sold or transferred Production Partnership Property.  Proceeds in excess of
said amount shall be allocated in accordance  with the  percentages set forth in
Section  5.3B(i) , except that,  notwithstanding  the provisions of Section 5.3F
and solely for purposes of this Section 5.3G,  where the proceeds from such Sale
are  distributed  to  the  Partners  and a  portion  of the  Distributable  Cash
attributable  to such Sale  proceeds is  sufficient in amount to cause Payout to
occur in  accordance  with the  allocation  percentages  in effect until Payout,
Payout  shall be  deemed  to occur  such  that  Income  and  Distributable  Cash
attributable to the portion of such Sale proceeds in excess of



                                      -47-
<PAGE>



the  portion of Sales  proceeds  sufficient  in amount to cause  Payout to occur
shall be allocated in accordance with the allocation percentages in effect after
Payout.

      H.  Notwithstanding  any other provision of this Agreement,  if, under any
provision of this  Agreement,  the Capital Account of any Partner is adjusted to
reflect  the  difference  between  the basis to the  Production  Partnership  of
Production  Partnership Property and such Production Partnership Property's fair
market value,  then all items of Income,  gain, loss, and deduction with respect
to such Production Partnership Property shall be allocated among the Partners so
as to take  account  of the  variation  between  the  basis  of such  Production
Partnership  Property and its fair market value at the time of the adjustment to
such Partner's Capital Account in accordance with the requirements of subsection
704(c) of the Code, or in the same manner as provided under subsection 704(c) of
the Code.

      I.    Notwithstanding anything to the contrary stated herein,

            (a) There shall be allocated to the Managing Partners, pro rata, any
      item of loss,  deduction,  credit or allowance  that, but for this Section
      5.3I,  would have been allocated to the other General  Partner that is not
      obligated to restore any deficit balance in such Partner's Capital Account
      and would have  thereupon  caused or  increased a deficit  balance in such
      Partner's  Capital  Account as of the end of the Production  Partnership's
      taxable  year  to  which  such  allocation   related  (after  taking  into
      consideration the provisions of Subsection 5.3D(v) hereof);

            (b) Any General Partner that is not obligated to restore any deficit
      balance in such Partner's  Capital  Account who  unexpectedly  receives an
      adjustment,  allocation or  distribution  specified in Subsection  5.3D(v)
      hereof shall be allocated items of Income and gain in an amount and manner
      sufficient to eliminate such deficit balance as quickly as possible; and

            (c) In the  event  any  allocations  of loss,  deduction,  credit or
      allowance are made to the Managing Partners pursuant to clause (a) of this
      Subsection 5.3I, the Managing Partners shall be subsequently allocated all
      items of Income and gain until the aggregate amount of such allocations of
      Income and gain is equal to the aggregate



                                      -48-
<PAGE>



      amount of any such  allocations  of loss,  deduction,  credit or allowance
      allocated to such Partners pursuant to clause (a) of this Subsection 5.3I.

      Section 5.4.  Determinations of Allocations and Distributions
      -------------------------------------------------------------

      Distributable Cash, Income, Investment Income, costs, deductions,  Profits
and Losses  allocable to the Partners shall be distributed or allocated,  as the
case may be, to the Persons who were Partners,  as of the last day of the fiscal
period for which the  distribution  or allocation is to be made,  except that in
any fiscal period in which a Partner sells, assigns or transfers all or any part
of such  Partner's  Interest  to any Person  who  during  the  fiscal  period is
admitted as a Substituted  Partner,  the Distributable Cash, Income,  Investment
Income,  costs,  deductions,  Profits and Losses attributable to the Interest so
sold,  assigned or transferred shall,  subject to the provisions of Section 10.2
of this Agreement, be allocated between the transferor and the transferee on the
basis of the number of days in the fiscal  period before the  admission,  and on
and after the admission,  of the transferee as a Substituted Partner;  provided,
however,  that the  Distributable  Cash  attributable  to a Sale of a  Producing
Property  shall be distributed to those Partners who are Partners on the day the
distribution  of such  Distributable  Cash occurs.  The Managing  Partners shall
inform the other  Partners of the  occurrence  and terms of any such Sale by the
Production  Partnership  as  soon  as  practicable  after  such  Sale  has  been
consummated.

                 Transferability of Managing Partner's Interests
                 -----------------------------------------------

      Section 6.1.  Transferability of Managing Partner's Interest
      ------------------------------------------------------------

        A. Except as provided in Sections  6.lB and 6.2B,  each of the  Managing
Partners  shall not have the right to retire,  withdraw,  transfer or assign its
Managing Partner Interest,  except that there may be substituted in its stead as
Managing  Partner any entity that has, by merger,  consolidation  or  otherwise,
acquired  substantially  all of its assets or capital  stock and  continued  its
business.



                                      -49-
<PAGE>




        B. Each Managing  Partner may, upon at least ninety days' written notice
to the Limited Partnership and the other Managing Partner,  cause the Production
Partnership  to  distribute,  in  partial  liquidation  of its  Interest  in the
Production Partnership, to such Managing Partner fractional, undivided interests
in the Producing  Properties of the Production  Partnership  (such interest of a
Managing Partner in a Producing Property  distributed is hereinafter referred to
as the "Distributed Interest") up to an aggregate interest equal in value to 75%
of the value of the Producing  Properties of the Production  Partnership that it
would have been entitled to upon a  hypothetical  liquidation  of the Production
Partnership after application of the provisions of Section 8.2 of this Agreement
(the  interest in a Producing  Property  of a Managing  Partner  retained in the
Production  Partnership is hereinafter  referred to as the "Retained  Interest")
provided, however, that no such distribution shall occur (i) more than once with
respect to a Managing Partner, (ii) prior to seven years after the Activation of
the Production  Partnership  and (iii) unless such Managing  Partner  obtains an
opinion  of  counsel  to the  Production  Partnership  to the  effect  that such
distribution  will not result in any  material  adverse tax  consequence  to the
other Managing Partner or to the Limited Partners.  Notwithstanding  anything to
the contrary in this Agreement, in the event that any such distribution is made,
appropriate  adjustments  shall be made in the Capital  Accounts of the Partners
and in the allocation of Production  Partnership Income and costs to assure that
the other Managing  Partner will not share or participate in any of the capital,
costs, Income, or distributions  attributable to the Producing Properties of the
Production  Partnership  except to the extent of the  Retained  Interest of such
Managing Partner.

       Section 6.2.  Removal of Managing Partners
       ------------------------------------------

       A.   (i) The power shall be vested in the Limited  Partnership  to remove
            at any time any Managing  Partner.  The power shall be vested in the
            Limited  Partnership  to consent  to the  admission  of a  successor
            Managing  Partner  following the Removal of any Managing  Partner by
            the Limited  Partnership.  A  successor  Managing  Partner  shall be
            selected  pursuant  to  the  provisions  of  Section  6.2D  of  this
            Agreement.



                                      -50-
<PAGE>




             (ii) (a) A  Managing  Partner  shall  have the power to Remove  the
            other  Managing  Partner,  and  pursuant  to  Section  l0.lA of this
            Agreement,  admit a  successor  Managing  Partner,  for  "Cause"  as
            defined in Section 6.2A(ii)(b), but for no other reason.

                    (b) "Cause" for  purposes  of Section  6.2A(ii)(a)  shall be
            deemed  to exist  only (i)  when a court of  competent  jurisdiction
            shall have made a final  determination  (which  determination is not
            successfully  appealed)  that a Managing  Partner has been guilty of
            gross negligence, fraud, intentional misconduct or similar breach of
            fiduciary  responsibility  in carrying  out its duties as a Managing
            Partner,  or (ii) a Managing  Partner is dissolved or  liquidated on
            account of  insolvency  or any other event  occurs  resulting in the
            appointment  of a trustee or receiver  who  acquires  control of the
            affairs of such Managing  Partner for the purpose of  dissolution or
            liquidation on account of  insolvency,  and such trustee or receiver
            is not dismissed within 90 days after appointment of such trustee or
            receiver,  or (iii) (a) a report on the audited financial statements
            of a Managing Partner and its consolidated  corporate  affiliates is
            issued by the independent accountants for such Managing Partner that
            is  qualified  on a going  concern  basis,  or (b)  either  Managing
            Partner  requests  an audit to be  performed  of the other  Managing
            Partner and its consolidated corporate affiliates by the independent
            accountants  for the other  Managing  Partner  (the  expense of such
            audit being paid by the Managing Partner requesting the audit) , and
            such audit results in the issuance of an opinion with respect to the
            financial   statements  of  the  other  Managing   Partner  and  its
            consolidated  corporate affiliates for the period ending, and as of,
            the most recent date feasible,  that is qualified on a going concern
            basis.

      B.    (i) In the event that a Managing  Partner is  Removed,  the  Removed
            Managing Partner's  Interest in the Production  Partnership shall be
            transferred  to the other Managing  Partner,  and the other Managing
            Partner  shall assign to the Removed  Managing  Partner a portion of
            Production  Partnership Income,  costs and Distributable Cash as and
            when such items are allocated or distributed, as the case may be, by
            the



                                      -51-
<PAGE>



            Production  Partnership  equal  to the  percentage  interest  of the
            Removed Managing Partner in the Production  Partnership prior to its
            Removal;  provided,  however,  that such assignment shall be reduced
            proportionately in the event of a foreclosure or sale referred to in
            Section 4.3D with respect to the Removed Managing Partner's interest
            transferred  to the  other  Managing  Partner  to the  extent of the
            foreclosed or sold interest.

            (ii) If a sole Managing Partner is Removed and a successor  Managing
            Partner is to be admitted to the Production Partnership, the removed
            Managing  Partner  shall not be Removed  until a successor  Managing
            Partner has been admitted to the Production  Partnership pursuant to
            Article 10 of this Agreement.

            (iii) In the event a sole Managing Partner is Removed by the Limited
            Partnership and a successor Managing Partner is to be admitted,  the
            incoming Managing Partner and the Removed Managing Partner shall, by
            mutual  agreement,  select an  independent  petroleum  consultant to
            value the Removed  Managing  Partner's  Interest  in the  Production
            Partnership.  In  determining  the value of the  Managing  Partner's
            Interest,   the  independent   consultant  will  take  into  account
            appropriate discount factors in light of the risk of recovery of oil
            and gas  reserves,  and, in any event,  will utilize a "risk factor"
            discount  no less  than  that  utilized  in the  most  recent  offer
            extended  pursuant  to  Section  7.5  of  the  Limited   Partnership
            Agreement,  if any. The incoming Managing Partner, or the Production
            Partnership,  shall have the option to  purchase at least 20% of the
            Interest of the Removed Managing Partner for the value determined by
            the independent  appraisal.  The Removed Managing Partner's Interest
            in the Production  Partnership shall be transferred to the successor
            Managing Partner, and the successor Managing Partner shall assign to
            the Removed  Managing  Partner a portion of  Production  Partnership
            Income,  costs and  Distributable  Cash as and when  such  items are
            allocated  or  distributed,  as the case may be,  by the  Production
            Partnership equal to the percentage interest of the Removed Managing
            Partner in the  Production  Partnership  prior to Removal,  less the
            portion   purchased  by  the  successor   Managing  Partner  or  the
            Production Partnership.

      C. Notwithstanding  Section 3.6, any Managing Partner who shall be Removed
pursuant  to the  provisions  of  Section  6.2  shall be  released  by the other
Partners from all liability for  Production  Partnership  debts and  obligations
incurred by the Production Partnership prior to the date of such Removal.

      D. Under  circumstances in which the Limited  Partnership  Consents to the
admission  of a successor  Managing  Partner,  such  admission  shall not become
effective unless the Production  Partnership  shall have received a certificate,
duly executed by or on behalf of such proposed successor Managing Partner to the
effect  that  it is  experienced  in  the  performance  (or  employs  sufficient
personnel who are experienced in performing) of functions of the type then being
performed by the Removed Managing Partner.

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

        Section 7.1.  Transferability of Limited Partnership's Interest
        ---------------------------------------------------------------

      No Sale,  exchange,  transfer or assignment  of the Limited  Partnership's
Interest may be made if in the opinion of counsel to the Production Partnership,
such Sale, exchange, transfer or assignment,  would (i) result in the Production
Partnership  being  considered to have terminated  within the meaning of Section
708 of the Code, or (ii) cause the Production  Partnership to lose its status as
a  partnership  for Federal  income tax  purposes.  In  addition,  the  Managing
Partners may require an opinion of the transferor's counsel, satisfactory to the
Managing Partners,  that such Sale,  exchange,  transfer or assignment would not
violate the Securities Act of 1933, as amended, or any state securities or "blue
sky" laws.


      Section 7.2.  Incapacity of Partners
      ------------------------------------

      If a Partner  (including a Managing  Partner) becomes  Incapacitated,  the
Person  who is its legal  representative  shall have all the rights of a Partner
for the purpose of settling or




                                      -53-
<PAGE>




managing  its estate and such power as the  Incapacitated  Partner  possessed to
assign  all or any  part of its  Interest  and to join  with  such  assignee  in
satisfying conditions precedent to such assignee becoming a Substituted Partner.
The Incapacity of a Partner shall not dissolve the Production Partnership.

      Section 7.3.  Assignees and Substituted Partners
      ------------------------------------------------

      A. The  Production  Partnership  shall not  recognize  for any purpose any
purported sale, assignment or transfer of all or any fraction of the Interest of
the Limited  Partnership  unless the  provisions  of Section 7.1 shall have been
complied with and there shall have been filed with the Production  Partnership a
dated  Notification  of  such  sale,   assignment  or  transfer,   executed  and
acknowledged  by both the seller,  assignor  or  transferor  and the  purchaser,
assignee or transferee and such  Notification (i) contains the acceptance by the
purchaser,  assignee or  transferee  of all of the terms and  provisions of this
Agreement and (ii) represents that such sale, assignment or transfer was made in
accordance with all applicable  laws and  regulations.  Any sale,  assignment or
transfer shall be recognized by the  Production  Partnership as effective on the
date of such  Notification if the date of such Notification is within 30 days of
the date on which such  Notification  is filed with the Production  Partnership,
and otherwise shall be recognized as effective on the date such  Notification is
filed with the Production Partnership.

      B. If the Limited  Partnership assigns all of its Interest to an assignee,
the Limited Partnership shall cease to be a Partner.

      C. A Person who is the  assignee of all or any fraction of the Interest of
the Limited  Partnership  shall be subject to all the provisions of this Article
Seven to the same  extent  and in the same  manner  as the  Limited  Partnership
desiring to make an assignment of its Interest.

      D. Any purchaser,  assignee,  transferee,  donee,  heir,  legatee or other
recipient of an Interest  shall be admitted to the  Production  Partnership as a
Substituted  Partner only with the Consent of the other Partners,  which Consent
may be  granted  or  withheld  by such  Partners  at  their  sole  and  absolute
discretion.  The  admission  of such Person as a  Substituted  Partner  shall be
evidenced  by the  execution  by the Partners of a  certificate  evidencing  the
admission of such Person as a Partner



                                      -54-
<PAGE>



and an amendment to this  Agreement  executed by the Managing  Partners on their
own behalf, as well as on behalf of each other Partner, pursuant to the power of
attorney granted pursuant to Section 12.5 of this Agreement.

      E. No Person shall become a  Substituted  Partner  until such Person shall
have satisfied the requirements of Section 10.2; provided, however, that for the

              (vi) the happening of any other event causing the  dissolution  of

      Section 8.2.  Liquidation
      -------------------------

      A. Upon dissolution of the Production  Partnership,  its liabilities shall
be paid in the  order  provided  herein.  The  Managing  Partners  shall  either
distribute in kind or sell the  Production  Partnership's  property so that such
disposition is in




                                      -56-
<PAGE>




the best interests of the Limited Partnership,  and shall execute all amendments
terminating  the Production  Partnership.  In connection with any such Sale, the
Managing  Partners  shall  attempt to obtain the best prices for such  property.
Pending such Sales,  the Managing  Partners  shall have the right to continue to
operate and otherwise to deal with Production Partnership property. In the event
the Production  Partnership is dissolved on account of the Incapacity or Removal
of the sole  Managing  Partner,  the  Production  Partnership  shall  elect,  in
accordance  with the provisions of Article  Eleven,  a person (the  "Liquidating
Agent") to perform the function of a Managing  Partner in liquidating the assets
of the Production  Partnership and winding up its affairs, and shall pay to such
Liquidating  Agent its  reasonable  fees and  expenses  incurred  in  connection
therewith.  Gain or  loss  realized  on the  Sale or  other  disposition  of the
Production  Partnership's  assets  will be  credited to (in the case of gain) or
charged  against  (in the case of loss) each  Partner's  Capital  Account to the
extent  allocable  to it under  Sections 5.3 and 5.4 of this  Agreement.  In the
event of a distribution  in kind of (a) any property other than an interest in a
Producing  Property,  each Partner's  Capital  Account shall be debited with the
portion of the Production  Partnership's  adjusted basis thereof attributable to
the interest  therein  distributed  to it and (b) any  Producing  Property or an
interest in any Producing  Property,  each Partner's Capital Account shall first
be  credited  or  debited  with its  share  of the  unrealized  appreciation  or
depreciation in the fair market value of said Producing  Property or interest in
said Producing Property. Each Partner's share of said unrealized appreciation or
depreciation  shall be equivalent to its share  (allocated  pursuant to Sections
5.3 and 5.4 of this  Agreement)  of the gain or loss on an  actual  Sale of such
Producing  Property or interest therein.  The Capital Account of each Partner to
whom a Producing  Property or an interest in a Producing Property is distributed
shall  be  debited  with  the  fair  market  value  of  the  Producing  Property
distributed  to it. Any  liquidation of the  Production  Partnership  shall take
place out of court and without  application being made therefor to the Secretary
of State of the State of Oklahoma.

      B. In settling  accounts after  dissolution,  the assets of the Production
Partnership  shall  be paid  out in the  following  order:  (i) to  third  party
creditors,  in the order or priority as  provided by law;  (ii) to the  Managing
Partners  and  any  Liquidating   Agent  for  any  expenses  of  the  Production
Partnership  paid by or  payable  to them to the  extent  they are  entitled  to
reimbursement therefor pursuant to this Agreement; (iii) to the




                                      -57-
<PAGE>




Limited  Partnership  in the amount  equivalent  to the  amount of its  positive
Capital Account  balances (as adjusted  pursuant to Section 8.2A) on the date of
distribution;  (iv) to the  Managing  Partners in the amount  equivalent  to the
amount of their  positive  Capital  Account  balances (as  adjusted  pursuant to
Section 8.2A) on the date of distribution;  and (v) the balance shall be paid to
the  Partners in the manner  provided  for by Sections  5.1, 5.3 and 5.4 of this
Agreement with respect to Distributable Cash.

      C. If any Managing  Partner has a deficit  balance in its Capital  Account
following the distribution(s)  provided for in Section 8.2B above, as determined
after taking into account all adjustments to its Capital Account for the taxable
year of the Production  Partnership during which such distribution(s)  occur, it
shall restore the amount of such deficit  balance to the Production  Partnership
within 90 days and such account  shall be  distributed  to the other  Parties in
accordance with their positive Capital Account balances.

      D. Upon the liquidation or partial  liquidation of any Managing  Partner's
Interest  pursuant to Article 6 hereof,  distribution  to the  Managing  Partner
whose  Interest is being  liquidated  shall be made pro rata to such  Partner in
accordance  with and to the extent of such Partner's  positive  Capital  Account
balance  after the  Partners'  Capital  Accounts  are  adjusted as if all of the
Production  Partnership's  property  had  been  sold at its  fair  market  value
immediately  prior to such  distribution  and the gain or loss  realized on such
sale charged or credited to the Partners'  Capital  Accounts in accordance  with
the provisions of Article 5 hereof, provided,  however, that if such Partner has
a deficit  balance  in its  Capital  Account  following  such  distribution  (or
adjustment of such  Partner's  Capital  Account  pursuant to this Section 8.2D),
such Partner shall restore the amount of such deficit  balance to the Production
Partnership by the later of the end of the Production  Partnership  taxable year
in which the liquidation of such Partner's  Interest occurs or 90 days after the
date of such liquidation.
