       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



                                      -7-
<PAGE>




                  (2) "Proved Developed Non-Producing 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;  provided  that proved  reserves for other
       undrilled  units  can  be  claimed  where  it can  be  demonstrated  with
       certainty,  based on accepted  geological,  geophysical  and  engineering
       studies and data, that there is continuity of production from an existing
       productive  formation.  No estimates for Proved Undeveloped  Reserves are
       attributable to any acreage for which improved  recovery is contemplated,
       unless the techniques to be employed have been proved effective by actual
       tests in the same area and reservoir.

       "Remove",  "Removed"  or  "Removal"  shall mean,  with  reference  to the
removal of the Managing  Partner,  the  termination  of the  management  powers,
duties and  responsibilities of the Managing Partner pursuant to Section 6.2 and
the removal of the Managing Partner as a Partner.

       "Royalty"  shall mean an interest,  including an overriding  royalty,  in
gross  production  or the  proceeds  therefrom  which does not require the owner
thereof  to  bear  any of the  cost of  production,  development,  operation  or
maintenance.

       "Sale" shall mean any event or  transaction  that is, for federal  income
tax purposes,  considered a sale, exchange or abandonment by the NPI Partnership
of any NPI Partnership Property.

       "State" shall mean the State of Oklahoma.

       "Substituted   Partner"  shall  mean  any  Person  admitted  to  the  NPI

this  Agreement to the extent that the amount of Income  allocated to it (and/or
the amount of NPI Partnership borrowings incurred on its behalf) is insufficient
to pay such costs.

       Section 3.2.  Other General Partner

       The name, address and Capital Contribution of the Limited Partnership are
set forth in Schedule A attached hereto and are hereby incorporated herein.

       Section 3.3.  Application of Capital Contributions

       The Managing  Partner  shall deposit in the NPI  Partnership  Account the
Capital  Contributions  of the Limited  Partnership and the Managing Partner and
apply such Capital  Contributions  to the payment of the  Acquisitions  Fee. The
balance  of such  Capital  Contributions  shall  be held in the NPI  Partnership
Account to be applied to the payment of Property  Acquisition  Costs and, to the
extent not payable out of Income or  Investment  Income,  Direct  Administrative
Costs and other NPI Partnership costs (except General and Administrative  Costs)
allocable to the Limited Partnership;  provided, however, that such funds may be
temporarily  invested  prior to the  payment  of such costs in  accordance  with
Section 9.3.

       Section 3.4.  Certain Returns of Capital

       Any  portion  of the  Capital  Contribution  of the  Limited  Partnership
(except for necessary  operating  capital) that has not been expended or that is
not, or in the determination of the Managing Partner,  will not be committed for
expenditure by the second  anniversary of the Activation of the NPI  Partnership
will promptly be refunded to the Limited  Partnership as a return of part of its
Capital  Contribution  at the  earlier  of  such  determination  or  the  second
anniversary of the Activation of the NPI Partnership.  In addition, the Managing
Partner shall contribute cash to the NPI Partnership  (with respect to which its
Capital  Accounts will be credited) in an amount equal to the amount paid to the
Managing  Partner  in  respect  of  the  Acquisitions  Fee  attributable  (on  a
proportionate  basis) to the  unexpended  amount  of  Capital  Contributions  so
refunded,  which cash shall be refunded to the Limited Partnership together with
the unexpended  Capital  Contributions so refunded.  Geodyne Production shall be
responsible for the obligation of the Managing Partner to contribute cash to the
NPI  Partnership  pursuant to this  Section  3.4. All amounts so refunded to the
Limited Partnership shall reduce dollar for dollar its Capital Account.

disproportion therein as between Partners.

       B. The NPI Partnership shall not redeem any Partner's Interest. Except as
provided in Sections  3.4,  6.1, 6.2 and 8.2, no Partner shall have the right to

involving a return of any Capital Contribution,  no Partner shall have the right
to receive any property other than cash,  except as may otherwise be provided in
Sections 6.1, 6.2 and 8.2.

       Section 3.6.  Liability of Partners

       Each  Partner  signatory  hereto  or  subsequently  admitted  to the  NPI
Partnership  agrees that it shall remain  generally liable for any obligation or
recourse liability of the NPI Partnership incurred during the period in which it
is a Partner.  However,  all  present  and future  Partners  hereby  agree among
themselves  to  contribute  to each  other  the  amount  of funds  necessary  to
effectuate  a  sharing  of  such  NPI   Partnership   obligations  and  recourse
liabilities  in  proportion  to each  Partner's  share of such  obligations  and
liabilities at the time of their accrual.

all specific  rights and powers required or appropriate to its management of the
NPI  Partnership's  business  which,  by way of  illustration  but not by way of
limitation, shall include the following rights and powers to:

             (i) expend the Capital  Contributions of the Partners and apply NPI

       acquisition  of an  interest  in a  Producing  Property,  or as  soon  as
       practicable  thereafter,  file or cause to be filed  for  recordation  an
       appropriate  conveyance  or agreement  evidencing  the NPI  Partnership's
       interest  in such  Producing  Property  in the  jurisdiction  where  such
       Producing  Property is located  pursuant to such  jurisdiction's  Uniform
       Commercial  Code  and/or  in the real  property  records  of the clerk or
       recorder of the county in which the Producing Property is situated;  and,
       provided,  further,  that filings of such conveyances or agreements shall
       also be made as the Managing Partner believes  necessary to establish the
       NPI Partnership's priority of interest; and, provided, further, Producing

       if such action is deemed  necessary by the Managing Partner to facilitate
       the acquisition and  administration  of such interest and if such nominee
       record holder conducts no other business or operations other than holding
       record title to interests in properties;

            (iii) execute such  instruments and agreements,  to do such acts, to
      employ  such  persons and to contract  for such  services as the  Managing

      Investment Company Act of 1940, as amended;

            (v) subject to Section  4.3B,  abandon or  otherwise  dispose of any

      purposes of the NPI  Partnership  for which the proceeds of borrowings may
      be applied;

            (vii) borrow  monies from time to time,  for the purpose and subject
      to the limitations  stated in Section 4.3C of this Agreement,  in the form
      of recourse or nonrecourse borrowings, or otherwise to draw, make, execute
      and  issue   promissory   notes  and  other  negotiable  or  nonnegotiable
      instruments and evidences of  indebtedness,  and to secure the payments of
      the sums so borrowed  and to mortgage,  pledge,  or assign in trust all or
      any part of NPI Partnership Property,  including Net Profits Interests and
      Royalties,  production and proceeds of production, or to assign any monies
      owing or to be owing to the NPI  Partnership,  and to  engage in any other
      means of financing customary in the petroleum industry; provided, however,
      that a creditor who makes a nonrecourse loan to the NPI Partnership  shall
      not have or  acquire,  at any time as a result  of making  the  loan,  any
      direct or indirect  interest in the profits,  capital,  or property of the
      NPI Partnership other than as a secured creditor;

      for such other things,  whether  similar or  dissimilar,  as may be deemed
      necessary or  appropriate  for carrying on and  performing the business of
      the NPI Partnership;

            (xi) enter into such  agreements and contracts with such parties and
      to give such receipts,  releases,  and discharges  with respect to any and
      all of the  foregoing  and any matters  incident  thereto as the  Managing
      Partner may deem advisable or appropriate;

<PAGE>




            (xv)  purchase  insurance,  or extend the Managing  Partner's or its
      Affiliates'  insurance,  at the NPI Partnership's  expense, to protect the

      the Managing Partner deems appropriate;

            (xvi) pay all ad valorem  taxes  levied or assessed  against the NPI
      Partnership  Properties,  all taxes upon or measured by the  production of
      Hydrocarbons  therefrom,  and all other taxes  (other  than income  taxes)
      directly related to operations conducted by the NPI Partnership;

            (xvii) enter into agreements on behalf of the NPI  Partnership  with
      Affiliates subject to the limitations set forth in Section 4.3C;

            (xviii) sell a portion or all or substantially all of the properties
      and  other  assets  of  the  NPI  Partnership  to  itself,  or  any of its
      Affiliates or  Affiliated  Programs or any other person and to receive for
      the NPI 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 it deems in the best
      interests of the Unit Holders; 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 NPI Partnership followed by any such sale of the

       Consent of the Limited Partnership  pursuant to the provisions of Section
       4.4B;

             (xx) take such other  action and perform  such other acts as may be
       deemed appropriate to carry out the business of the NPI Partnership; and

             (xxi) inform each other Partner of all  administrative and judicial
       proceedings  for  an  adjustment  at  the  NPI   Partnership   level  for

       imposed by Sections  6221  through  6232 of the Code as the "tax  matters
       partner"  of the NPI  Partnership,  including,  but not  limited  to, the
       following:  (a) the power to conduct all audits and other  administrative
       proceedings  (including  windfall  profit tax audits) with respect to NPI
       Partnership items; the power to extend the statute of limitations for all
       Partners with respect to NPI Partnership tax items;  and (b) the power to
       file a petition with an  appropriate  federal court for review of a final

       B. No person,  firm or corporation dealing with the NPI Partnership shall
be required to inquire into the  authority  of the  Managing  Partner to take or
refrain from taking any action or make or refrain from making any decision,  but
any person so  inquiring  shall be  entitled to rely upon a  certificate  of the
Managing Partner as to its due authorization.

       Section  4.3.   Sales,   Purchases   and   Management  of  Net  Profits
Interests and Royalties; Additional Financing

       A.  The  provisions  of  Section  4.3C  notwithstanding,  if one or  more
Affiliated  Programs intends to acquire Working  Interests,  acquisitions of Net
Profits  Interests by the NPI  Partnership  may be made in connection  with such
Affiliated  Program's  acquisitions of Working Interests.  Net Profits Interests
acquired  by the NPI  Partnership  may either be  carved-out  of the  Affiliated
Program's Working Interests or reserved from the limited partnership Affiliate's
Working  Interests by the sellers of such Working Interests on such basis as the
Managing  Partner  determines.  Any  Net  Profits  Interest  acquired  by an NPI
Partnership may not exceed 75% of the net profits  attributable to the aggregate
Working  Interests in the Producing  Properties  acquired by the NPI Partnership
and Affiliated  Program together.  The primary factor in determining the sharing
of net profits between the Working Interests  acquired by the Affiliated Program
and the Net Profits Interest  acquired by the NPI Partnership will be the amount
of money  contributed  to each  acquisition  by each  purchaser.  In fixing such
sharing percentages, the Managing Partner need not give special consideration to
risks  associated  with the  ownership  of the Working  Interests or to costs of
equipment  which will be owned by the  Affiliated  Program  as Working  Interest
owners if such costs  will be  amortized  against  the  proceeds  of oil and gas
production  in  arriving  at the  amount  of net  profits  from  which  the  NPI
Partnership's   (as  Net  Profits   Interest  holder)  share  of  production  is
determined.  If the NPI Partnership  acquires a Royalty  interest in a Producing
Property in which a Working Interest is acquired by the Affiliated Program, each
participant's  portion of the purchase  price will be determined on the basis of
an appraisal by the Managing Partner's  petroleum reservoir engineer of the fair
market values of the respective interests in the property being acquired (taking
into account the tax consequences  applicable to the several  participants).  If
the Managing  Partner or an Affiliate other than an Affiliated  Program acquires
an interest in any such property  acquisition,  such appraisal will be performed
by an independent  petroleum  engineer and if the aggregate  revenue interest of
the Managing Partner and its Affiliates in any Affiliated Program participant in
such a property  acquisition is greater than their aggregate revenue interest in
the NPI Partnership, then with respect to the property interests so acquired the
greater  aggregate  revenue  interest  shall be  reduced so as not to exceed the
lesser revenue interest.

       B. Net Profits  Interests and Royalties  whose purchase price exceeds 10%
of the Unit Holders' Subscriptions to the Limited Partnership may be acquired by
the NPI  Partnership  only if an  Acquisition  Reserve  Report or an Engineering
Audit Letter has been prepared and evaluated with respect thereto.



                                      -15-

       C. Neither the Managing Partner nor any Affiliate shall sell, transfer or
convey any or all of its  interest in a Producing  Property  (including  any Net
Profits  Interests and any Royalty  interest  therein) to the NPI Partnership or
purchase  or  acquire  any oil and  gas  properties  or  interest  from  the NPI
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 NPI  Partnership  has  fully
       expended  that  portion of its  Capital  Contribution  available  for the
       acquisition of Net Profits Interests and Royalties,  neither the Managing
       Partner  nor  any  Affiliate  of the  Managing  Partner  (other  than  an
       Affiliated  Program) shall acquire an interest in any Producing  Property
       after the Activation of the NPI Partnership  unless prior thereto the NPI
       Partnership  shall have been  offered the right to acquire an interest in
       such Producing Property, or an interest therein, and the Managing Partner
       shall  have  determined  that  the  acquisition  of an  interest  in such
       Producing Property is not in the best interests of the NPI Partnership;

             (ii) Any  purchase or sale of an  interest in a Producing  Property
       from or to the  Managing  Partner or any  Affiliate  shall be made at the
       Property  Acquisition Cost for an interest in 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 the Managing Partner or its Affiliates sells, transfers or
       conveys any oil, gas or other  mineral  interests or property  (including
       Net Profits Interests and Royalties) to the NPI Partnership,  it must, at
       the  same  time,  sell  to the NPI  Partnership  an  equal  proportionate
       interest  in all its  other  property  in the  same  Prospect.  A Sale or
       conveyance  to the NPI  Partnership  of less  than the  entire  ownership
       interest of the Managing  Partner or any Affiliate is only  permitted if:
       (a) the  interests  retained  or  obtained  by the  Managing  Partner  or
       Affiliate   and   acquired  by  the  NPI   Partnership   are  either  (x)
       proportionate,  uniform  and  undivided  Net  Profits  Interests  if  the
       interest in a Producing Property acquired by the NPI Partnership is a Net
       Profits  Interest or (y)  proportionate,  uniform and  undivided  Royalty
       interests  if the  interest in a Producing  Property  acquired by the NPI
       Partnership is a Royalty, (b) the respective  obligations of the Managing
       Partner or Affiliate and the NPI Partnership are  substantially the same,
       and (c) the interest of the Managing Partner or its Affiliate in revenues
       does not exceed the amount  proportionate  to its interest.  The Managing
       Partner and its Affiliate may not retain or obtain any overrides or other
       burdens on the  interest  obtained  by the NPI  Partnership,  and may not
       enter into any Farmouts with respect to its retained interest,  except to
       nonaffiliated third parties or to an Affiliated Program;



                                      -16-
<PAGE>




            (iv) In the event the Managing Partner or any Affiliate  proposes to
      acquire an  interest  in a Prospect  in which the NPI  Partnership  has an
      interest or in a Prospect abandoned by the NPI Partnership within one year
      preceding  such proposed  acquisition,  the Managing  Partner or Affiliate
      shall offer the interest to the NPI Partnership;  and if cash or financing
      is not available to the NPI Partnership to purchase such interest, neither
      the  Managing  Partner  nor  Affiliate  shall  acquire an interest in such
      Prospect.  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 NPI Partnership's interest in the Prospect. This
      subsection shall not apply after the lapse of five years of the Activation
      of the NPI Partnership or to any Affiliated  Program where the interest of
      the Managing Partner or an Affiliate is less than or equal to its interest
      in the NPI  Partnership,  there are no duplication of fees to the Managing
      Partner or an Affiliate, and the Managing Partner or an Affiliate does not
      obtain a greater  benefit from purchase of the interest by the  Affiliated
      Program  than  it  would  if  the  interest  were  purchased  by  the  NPI
      Partnership;

            (v) During the  existence of the NPI  Partnership  and before it has
      ceased  operations,   neither  the  Managing  Partner  nor  any  Affiliate
      (excluding  any  Affiliated  Program  where the  interest of the  Managing
      Partner or an  Affiliate  is less than or equal to its interest in the NPI
      Partnership)  shall  acquire,  retain or drill for its own account any oil
      and gas interest in any Prospect upon which the NPI Partnership  possesses
      an interest,  except for transactions which comply with Section 4.3C(iii).
      The geological limits of a Prospect shall be enlarged or contracted on the
      basis of  subsequently  acquired  geological data to define the productive
      limits of a reservoir and shall  include all of the acreage  determined by
      the subsequent data to be encompassed by such reservoir. If the geological
      limits of a Prospect,  as so enlarged,  encompass any interest held by the
      Managing  Partner or an Affiliate of the Managing  Partner  (excluding  an
      Affiliated  Program  where the  interest  of the  Managing  Partner  or an
      Affiliate   is  identical  to  or  less  than  its  interest  in  the  NPI
      Partnership), such a Net Profits Interest therein shall be sold to the NPI
      Partnership in accordance with the provisions of Section  4.3C(iv) and any
      net income previously  received by the Managing Partner or Affiliate shall
      be  paid  over to the  NPI  Partnership.  If the  Managing  Partner  or an
      Affiliate  acquires  additional  acreage or interests in a Prospect of the
      NPI  Partnership,  it  must  sell  such  to  the  NPI  Partnership  and is
      prohibited from retaining any such interest, except as may be permitted by
      Section 4.3C.  Notwithstanding the foregoing,  neither the NPI Partnership
      nor the Limited Partnership will be required to expend additional funds to
      acquire any such  interest  unless  funds are  available  from the Capital
      Contributions of the Partners;



                                      -17-
<PAGE>




             (vi)  If a  Net  Profits  Interest  or  Royalty  held  by  the  NPI
       Partnership  burdens  undeveloped  acreage in which an Affiliated Program
       owns an interest,  the owner of such undeveloped leasehold interest shall
       have the  right  to farm out all or a  portion  of the  Working  Interest
       constituting  such  undeveloped  leasehold  interest,  and if the Working
       Interest remaining or reverting to the owner of the undeveloped leasehold
       interest is reduced by such Farmout,  the Net Profits Interest or Royalty
       shall be proportionately  reduced, but shall share proportionately in any
       benefits  derived from such Farmout.  In the event a Net Profits Interest
       does not, by its terms, provide the specific consequences of a Farmout of
       the Working Interest constituting such undeveloped leasehold interest and
       if such undeveloped leasehold interest is farmed out to an Affiliate, the
       Managing  Partner  may  subordinate  the NPI  Partnership's  Net  Profits
       Interest to such Farmout,  provided that the Net Profits  Interest  shall
       burden any Working  Interest or other interest  retained by, or which may
       revert to, the owner of the undeveloped  leasehold  interest  pursuant to
       any such Farmout. The terms of the Farmout will be consistent with and no
       less  favorable  to the  NPI  Partnership  than  the  terms  of  Farmouts
       prevalent in the geographic area for similar arrangements.

             (vii) Any  operating  agreements  pursuant  to which  the  Managing
       Partner  or any  Affiliate  acts  as  operator  of  Producing  Properties
       burdened with a Net Profits Interest owned by the NPI Partnership,  shall
       be of a nature  customary  in the  industry  and payments to the 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; and

             (viii) To the extent the Managing Partner or any Affiliate acquires
       an interest in a Producing Property in which the NPI Partnership acquires
       an interest,  the 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.

       D. If the  Managing  Partner  determines  that funds in  addition  to the
Capital Contributions to the NPI Partnership are required for the payment of NPI
Partnership costs (other than Property  Acquisition Costs), the Managing Partner
may apply or reserve  Income or  Investment  Income for the  payment of such NPI
Partnership  costs and/or the Managing  Partner may cause the NPI Partnership to
borrow  funds  for the  payment  of such  costs;  provided,  however,  that  the
aggregate  outstanding  principal amount of such borrowings shall not at any one
time  exceed an amount  equal to 5% of the Unit  Holders'  Subscriptions  to the
Limited Partnership.

       E. The 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 NPI Partnership  costs by assigning to lenders all or part of
its interest in Profits and  Distributable  Cash;  provided,  however,  that the
Managing  Partner,  shall retain  unencumbered at least a 1% interest in Profits
and Distributable



                                      -18-
<PAGE>



Cash.  Notwithstanding  anything to the contrary in this Agreement, in the event
of any sale or foreclosure of the Managing Partner's interest in full or partial
satisfaction of such borrowings:  (i) 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  will not
bear any of the costs attributable to such sold or foreclosed  interest and that
the  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 the  Managing
Partner; and (ii) the Limited  Partnership's share of General and Administrative
Costs and Direct Administrative Costs shall not be increased as a result of such
sale  or  foreclosure.   The  Managing   Partner  shall  indemnify  the  Limited
Partnership  against any expenses  resulting  from a sale or  foreclosure of the
Managing Partner's interest.

       Section 4.4.  Prohibited Transactions

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

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

             (ii) neither the Managing  Partner nor any Affiliate shall make any
       loans to the NPI  Partnership  except at a rate of interest not in excess
       of the interest  cost  incurred by the Managing  Partner or Affiliates or
       the amount of  interest  that  would be  charged  to the NPI  Partnership
       (without  regard  to the  Managing  Partner's  or  Affiliate's  financial
       abilities or guarantees) by unrelated  banks on comparable  loans for the
       same purpose, whichever is lower, and the Managing Partner 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 the Managing  Partner or any  Affiliate
       shall be compensated by the NPI Partnership for his or her services;

             (iv)  other  than  those  received  for  the  account  of  the  NPI
       Partnership,  no rebates may be received by the  Managing  Partner or any
       Affiliate in connection with NPI Partnership  operations or expenditures,
       nor  may  the  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 the
       Managing  Partner or an Affiliate for the account of the NPI  Partnership
       shall be  determined  and the net  amount  resulting  from  such  monthly
       settlement shall be deposited into a NPI Partnership Account and no funds
       which, after such monthly settlement, are



                                      -19-
<PAGE>



      determined to be held for the account of the NPI Partnership shall be kept
      in any account  other than a NPI  Partnership  Account,  and the  Managing
      Partner shall not employ, or permit any other Person to employ, such funds
      in any manner  except for the  benefit  of the NPI  Partnership;  it being
      understood  that the  Managing  Partner may invest NPI  Partnership  funds
      temporarily in the  investments set forth in Section 9.3 of this Agreement
      pending their use by the NPI Partnership.  After such monthly  settlement,
      NPI  Partnership  funds may not be commingled  with separate  funds of the
      Managing Partner or any other entity; and

             (vi) the Limited  Partnership shall not make any advance payment to
       the Managing Partner or its Affiliates.

       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 Partner shall not:

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

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

             (iii) except as set forth in Section  10.1A,  amend any provision
       of this Agreement; or

             (iv) dissolve the NPI Partnership.

       Section 4.5  Other Agreements of the Managing Partner

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

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

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

                  (b)   the commitment of future production;

             (ii)   all   benefits   from   marketing   arrangements   or  other

       and the  NPI  Partnership  shall  be  fairly  and  equitably  apportioned
       according to the respective interests of each;



                                      -20-

       Section  4.6.       Contracts    with   the   Managing    Partner   and
Affiliates

       All services  provided to the NPI Partnership by the 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 NPI
Partnership and the Managing  Partner or any Affiliate shall contain a provision
which shall permit  termination of the contract by the NPI  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
NPI Partnership.

       Section 4.7.    Other Operations

       The Managing  Partner shall devote such time to the NPI Partnership as is
reasonably required to carry on the NPI Partnership  business,  and the Managing
Partner  and  its  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. The Managing Partner will meet all fiduciary obligations that it owes to
the Limited Partnership and the Unit Holders. Without limiting the generality of
the foregoing,  the Managing  Partner and its Affiliates shall have the right to
organize and operate  other  partnerships,  joint  ventures or other oil and gas
investment programs similar to the Limited Partnership and the NPI Partnership.

       Section  4.8.       Prosecution,  Defense  and  Settlement  of  Claims;
Indemnification

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

       B. The Managing Partner and its Affiliates shall have no liability to the
NPI  Partnership  or to any Partner or Unit Holders for any loss suffered by the
NPI  Partnership  which  arises out of any action or  inaction  of the  Managing
Partner or its Affiliates if the Managing  Partner and its  Affiliates,  in good
faith,  determined  that such course of conduct was in the best interests of the
NPI  Partnership  and such course of conduct did not  constitute  negligence  or
misconduct of the Managing  Partner or its Affiliates.  The Managing Partner and
its Affiliates  shall be indemnified by the NPI Partnership  against any losses,
judgments,  liabilities,  expenses and amounts paid in  settlement of any claims
sustained by them in connection with the NPI Partnership, provided that the same
were not the result of  negligence  or  misconduct  on the part of the  Managing
Partner or its Affiliates.  Any indemnification  under this Section 4.8 shall be
satisfied  solely  out of the  Assets  and  Income of the NPI  Partnership.  All
amounts  payable  under  this  Section  4.8  shall  be a  liability  of the  NPI
Partnership only and no Unit Holders or Limited Partners will have any liability
therefor.



                                      -21-
<PAGE>




       C. Notwithstanding the above, the Managing Partner and its Affiliates and
any Person acting as a  broker-dealer  shall not be indemnified  for liabilities
arising  under  federal  and state  securities  laws unless (1) there has been a
successful  adjudication  on the merits of each count  involving  securities law
violations and the court approves such  indemnification and the litigation costs
thereof;  or (2) such claims have been dismissed with prejudice on the merits by
a court of competent  jurisdiction  and the court approves such  indemnification
and the litigation  costs thereof.  In any such case, the Managing Partner shall
apprise the court of the current  published  positions,  if any, of the federal,
the  Massachusetts  State Securities  Administrators  and other applicable state
securities administrators regarding indemnification of program sponsors prior to
obtaining court approval of any such indemnification.

       D. The NPI  Partnership  shall not incur  the  costs of that  portion  of
insurance  which insures the Managing  Partner for any liability as to which the
Managing Partner is prohibited from being indemnified under Section 4.8.

       E. For purposes of this Section 4.8,  the term  Affiliate  shall  include
only those Affiliates, as defined in Article I, performing services on behalf of
the NPI Partnership.

                                  ARTICLE FIVE
                       Distributions, Fees and Allocations

       Section 5.1.  Distributions of NPI Partnership Funds

       The  Distributable  Cash  of the NPI  Partnership  shall  be  distributed
simultaneously  to the Limited  Partnership  and the Managing  Partner within 45
days after the close of each calendar quarter. Each Partner's share of each such
distribution of Distributable Cash other than as specified in Section 5.3G shall
be based on the ratio of their  respective  positive  Capital Account  balances,
such balances being  determined after giving effect to the allocations set forth
in Sections  5.3 and 5.4 for such period.  All  distributions  of  Distributable
Cash,   including  sales  proceeds   pursuant  to  Section  5.3G,  shall  reduce
dollar-for-dollar the balances of the Partners' Capital Accounts.

       Section 5.2.       Fees and  Reimbursement  of Expenses to the Managing
Partner

       Geodyne Energy shall receive as Managing  Partner (1) upon Activation and
on a nonrecurring  basis, the Acquisitions Fee in an amount equal to 3.5% of the
Unit Holders'  Subscriptions;  and (2) reimbursement  for Direct  Administrative
Costs  billed  directly to the Managing  Partner and General and  Administrative
Costs incurred by the Managing  Partner or its  Affiliates  allocable to the NPI
Partnership,  except to the extent that the Managing Partner or its Affiliate is
otherwise  reimbursed for such costs through the payment of Property Acquisition
Costs or otherwise.  The aggregate  amount of General and  Administrative  Costs
allocable to the accounts of the Unit Holders for



                                      -22-
<PAGE>



which the Managing  Partner will be  reimbursed by the NPI  Partnership  and the
General Partner by the Limited  Partnership  will not (a) in the first 12 months
following  Activation of the NPI Partnership,  exceed an amount equal to 2.5% of
the Unit  Holders'  Subscriptions,  and (b) in any  succeeding  12 month period,
exceed an amount equal to 1% of the Unit Holders' Subscriptions.

       Section  5.3.   Allocation  of  Income,   Investment   Income,   Gains,
Losses, Deductions and Credits

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

       B. Except as otherwise provided in this Article Five

         (i)   100% of Investment Income,  Property Acquisition Costs, and the
               Acquisitions  Fee  referred to in Section  5.2(1)  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  Partner.  Except as otherwise  provided
               in this  Section  5.3B(i)  and  Sections  5.3B(ii)  and  (iii),
               Income,  gain,  General and  Administrative  Costs,  and Direct
               Administrative  Costs and other losses,  deductions and credits
               shall be  allocated  among,  and borne by, the  Partners in the
               following percentages:

               (a)  Until Payout:
                    Limited Partnership                     95.9596%

                    Geodyne Energy                           4.0404%

               (b)  After Payout:
                    Limited Partnership                     85.8586%

                    Geodyne Energy                          14.1414%

         (ii)  As used in this  subsection,  the  "Property  Investment  Period"
               shall mean that  period  which  begins  with the first day of the
               calendar quarter following either (i) the calendar quarter during
               which  90%  of  the  NPI  Partnership's   capital  available  for
               purchasing  Net  Profits  Interests  and  Royalties  has  been so
               expended,  or (ii) the  calendar  quarter in which 50% of the NPI
               Partnership's   capital  available  for  purchasing  Net  Profits
               Interests  and  Royalties  has been so expended,  as the Managing
               Partner shall elect,  and  terminates at Payout.  Notwithstanding
               anything to the contrary  contained  herein,  if, at Payout,  the
               total amount of cash distributions by the Limited  Partnership to
               the Unit Holders from the commencement of the Property Investment
               Period have  averaged on a  twelve-month  basis an amount that is
               less than 12% of the Unit Holders' Subscriptions,  the percentage
               of Income,  and costs which are shared in the same proportions as
               Income, allocated to the Managing



                                      -23-
<PAGE>



               and  General  Partners  will  increase  to only  10% and the Unit
               Holders will be allocated  90% thereof  until such time, if ever,
               that the  distributions to the Unit Holders from the commencement
               of the Property Investment Period reaches a twelve-month  average
               equal to at  least  12% of the Unit  Holders'  Subscriptions,  at
               which time Income,  gain and costs and other  losses,  deductions
               and  credits  shared in the same  proportions  as Income  will be
               allocated  14.1414% to the  Managing  Partner and 85.8586% to the
               Limited Partnership.

          (iii)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 Unit
               Holders'  Subscriptions  to the  Limited  Partnership  shall  not
               include any amounts attributable to the NPI Partnership's payment
               of any windfall profits tax.

         (iv)  Notwithstanding anything to the contrary contained herein, if and
               to the  extent  the NPI  Partnership  sells  any  Royalty  or Net
               Profits  Interest and applies any portion of the proceeds thereof
               to  the  purchase  of any  additional  Royalties  or Net  Profits
               Interests,  the  Property  Acquisition  Costs  of the  additional
               Producing  Property shall be allocated to and considered  charged
               to the  Managing  Partner  and  Limited  Partnership  in the same
               proportions  that such portion of sale  proceeds  would have been
               distributed to them, had the sale proceeds been distributed.

       C. All items of Income, gain, loss, expense, deduction and credit 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 NPI
Partnership  shall  allocate,  under  Section  613A(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 NPI 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
Partner deems 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:



                                      -24-
<PAGE>




            (i) 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 NPI Partnership (net of liabilities securing such
      contributed  property that the NPI  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  including  sales proceeds
      distributed to it, the fair market value of property  distributed to it by
      the NPI 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 NPI Partnership loss,  deduction
      (except to the extent such loss or deduction has previously been reflected
      in its Capital Account by adjustments thereto) and expenditures  described
      in section 705(a)(2)(B) of the Code.

            (ii) In the event  NPI  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 NPI 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
      NPI  Partnership  Property  for  its  fair  market  value  on the  date of
      distribution.

            (iii) If,  pursuant to this Agreement,  NPI Partnership  Property is
      reflected on the books of the NPI Partnership at a book value that differs
      from the adjusted  tax basis of such NPI  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 NPI Partnership Property.

            (iv) 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  choice  shall be binding for all NPI
      Partnership taxable years during which such oil or gas property is held by
      the NPI  Partnership.  Such  reductions for depletion shall not exceed the
      aggregate  adjusted basis  allocated to the Partners and Unit Holders with
      respect to such oil or gas property.  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  allocated to each
      Partner. Upon the taxable disposition of an oil or gas property by the NPI
      Partnership,  the  NPI  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



                                      -25-
<PAGE>



      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.

             (v) For purposes of determining  the Capital Account balance of any
       Partner as of the end of any NPI 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 NPI
             Partnership, and

                  (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 NPI
             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 NPI  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 NPI
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
NPI Partnership's Net Profits Interest or Royalties shall be distributed 100% to
the  Limited  Partnership  to the extent of its  adjusted  basis in such sold or
transferred NPI Partnership Property. Proceeds in excess of said amount shall be
distributed  100% in  accordance  with the  percentages  set  forth  in  Section
5.3B(i)(a) and (b), 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 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  NPI  Partnership  of NPI
Partnership Property and such NPI Partnership Property's fair market value, then
all  items of  Income,  gain,  loss,  and  deduction  with  respect  to such NPI
Partnership Property shall be allocated among the Partners so as to take account
of the variation between the basis of such NPI 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,

             (i) Subject only to the provisions of Section 5.3J,  there shall be
       allocated to the Managing Partner, 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 NPI  Partnership's  taxable year to which such  allocation
       related  (after taking into  consideration  the  provisions of Subsection
       5.3D(v) hereof);

             (ii) 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

             (iii) In the event any  allocations of loss,  deduction,  credit or
       allowance are made to the Managing Partner pursuant to clause (i) of this
       Subsection 5.3I, the Managing Partner 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  amount  of any  such
       allocations  of loss,  deduction,  credit or allowance  allocated to such
       Partners pursuant to clause (1) of this Subsection 5.3I.

       J. In the event there is a net  decrease in the  "minimum  gain," as that
term is defined in the 704  Regulations,  of the NPI  Partnership  during an NPI
Partnership  taxable year, all Partners with deficit Capital Account balances at
the end of such year shall be  allocated,  before any other  allocation  is made
under this Article Five, Income and gain of the NPI Partnership for such taxable
year (and, if necessary,  subsequent  years) in the amount and in the proportion
necessary to eliminate  such  deficits as quickly as possible.  The  allocations
required by this  Section  5.3J shall be made as  required by and in  accordance
with Section  l.704-1(b)(4)(iv)(e)  of the 704 Regulations.  It is intended that
the provision set forth in this Section 5.3J will



                                      -27-
<PAGE>



constitute   a   "minimum   gain    chargeback"    as   described   in   Section
1.704-l(b)(4)(iv)(e)  of the 704 Regulations.  The 704 Regulations shall control
in the case of any conflict between the 704 Regulations and this Section 5.3J.

       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 7.3 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 Net Profits
Interest or Royalty shall be  distributed  to those Partners who are Partners on
the day the distribution of such Distributable Cash occurs. The Managing Partner
shall inform the other  Partners of the occurrence and terms of any such Sale by
the NPI Partnership as soon as practicable after such Sale has been consummated.


                                   ARTICLE SIX
                  Withdrawal or Removal of Managing Partner

       Section 6.1.  Transferability of Managing Partner's Interest

       A. Upon 120 days Notification to all other Partners, the Managing Partner
may retire or withdraw from the NPI Partnership as Managing Partner,  subject to
its obligation to pay all costs and expenses  incurred by the NPI Partnership by
virtue of such retirement or withdrawal.  In addition,  there may be substituted
in its stead as Managing  Partner any entity that has, by merger,  consolidation
or otherwise,  acquired  substantially  all of the Managing  Partner's assets or
capital stock and continued its business.

       B.  Subject to Section  11.1 of this  Agreement,  upon the Consent of the
Limited Partnership,  which shall be given if the Consent of Unit Holders owning
more than 50% of the  outstanding  Depositary  Units is  obtained,  the Managing
Partner may assign or transfer its Managing Partner Interest; provided, however,
that no such  consent  shall be required in  connection  with an  assignment  or
transfer   pursuant  to  the  merger,   consolidation  or  transfer  of  all  or
substantially all of the assets of the Managing Partner.

       C. The Managing  Partner may, upon at least 90 days'  Notification to the
Limited  Partnership,  cause  the NPI  Partnership  to  distribute,  in  partial
liquidation  of its Interest in the NPI  Partnership,  to the  Managing  Partner
fractional,  undivided  interests in the Net Profits  Interests and Royalties of
the NPI Partnership (such interest of the



                                      -28-
<PAGE>



Managing Partner in a Net Profits Interest or Royalty distributed is hereinafter
referred to as the "Distributed  Interest") up to an aggregate interest equal in
value to 75% of the value of the Net Profits  Interests and Royalties of the NPI
Partnership that it would have been entitled to upon a hypothetical  liquidation
of the NPI Partnership  after  application of the provisions of Section 8.2 (the
interest in a Net Profits  Interest or Royalty of the Managing  Partner retained
in the NPI Partnership is hereinafter  referred to as the "Retained  Interest");
provided,  however,  that no such  distribution  shall occur (i) more than once,
(ii) prior to seven years after the Activation of the NPI  Partnership and (iii)
unless the Managing Partner obtains an opinion of counsel to the NPI Partnership
to the effect that such distribution will not result in any material adverse tax
consequence  to the Unit  Holders.  Notwithstanding  anything to the contrary in
this  Agreement,  in the event that any such  distribution is made, the Managing
Partner shall:

       (1)   make  appropriate  adjustments  in  the  Capital  Accounts  of  the
             Partners and in the allocation of NPI Partnership  Income and costs
             to assure that the Managing  Partner will not share or  participate
             in any of the capital, costs, Income, or distributions attributable
             to the Net Profits  Interests and Royalties of the NPI  Partnership
             except  to the  extent of the  Retained  Interest  of the  Managing
             Partner;

       (2)   not voluntarily or otherwise  dispose of its  Distributed  Interest
             unless the undivided  interest of the NPI  Partnership  in such Net
             Profits  Interests  and Royalties is also sold or disposed of for a
             proportionately equivalent consideration;

       (3)   ensure  that  the  Limited   Partnership's  share  of  General  and
             Administrative  Costs  and  Direct  Administrative  Costs  does not
             increase as a result of such withdrawal; and

       (4)   indemnify the Limited  Partnership  against any expenses  resulting
             from such withdrawal.

       Section 6.2. Removal of the Managing Partner

       The power  shall be vested in the  Limited  Partnership  to remove at any
time the 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 the Managing Partner by the Limited Partnership. A successor Managing
Partner  shall be selected  pursuant to the  provisions  of Section 6.3C of this
Agreement.

       Section 6.3.  Successor Managing Partner

       A. (i) If the Managing  Partner is Removed or  withdraws  and a successor
       Managing Partner is to be admitted to the NPI Partnership,  the departing
       Managing  Partner  shall not  withdraw  or be Removed  until a  successor
       Managing  Partner has been  admitted to the NPI  Partnership  pursuant to
       Article Ten of this Agreement.



                                      -29-
<PAGE>




          (ii) In the event the Managing Partner  withdraws or is Removed by the
     Limited Partnership and a successor Managing Partner is to be admitted, the
     incoming  Managing  Partner and the departing  Managing  Partner shall,  by
     mutual agreement,  select an independent  petroleum consultant to value the
     departing  Managing  Partner's  Interest  in  the  NPI  Partnership.  If no
     agreement  can be reached on the selection of a qualified  consultant,  the
     departing  Managing Partner and incoming Managing Partner shall each select
     an  independent  petroleum  consultant,  who together  shall select a third
     consultant,  and the three consultants shall together  determine a value of
     the  interests of the departing  Managing  Partner.  The incoming  Managing
     Partner, or the NPI Partnership, shall have the option to purchase at least
     20% of the  Interest  of the  departing  Managing  Partner  for  the  value
     determined by the independent  appraisal.  The departing Managing Partner's
     Interest  in the NPI  Partnership  shall be  transferred  to the  successor
     Managing  Partner,  and the successor  Managing Partner shall assign to the
     departing Managing Partner a portion of NPI Partnership  Income,  costs and
     Distributable Cash as and when such items are allocated or distributed,  as
     the case may be, by the NPI Partnership equal to the percentage interest of
     the departing  Managing Partner in the NPI Partnership  prior to withdrawal
     or Removal, less the portion purchased by the successor Managing Partner or
     the NPI Partnership.

       B. Notwithstanding  Section 3.6, the Managing Partner, upon withdrawal or
removal  shall be  released by the other  Partners  from all  liability  for NPI
Partnership  debts and obligations  incurred by the NPI Partnership prior to the
date of such withdrawal or Removal.

       C. Under circumstances in which the Limited  Partnership  Consents to the
admission  of a successor  Managing  Partner,  such  admission  shall not become
effective  unless the NPI  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 departing Managing Partner.

          Transferability of Limited Partnership's Interest

       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 NPI Partnership,  such
Sale, exchange, transfer or assignment,  would cause the NPI Partnership to lose
its status as a partnership  for federal income tax purposes.  In addition,  the
Managing   Partner  may  require  an  opinion  of  the   transferor's   counsel,
satisfactory  to the Managing  Partner,  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 the 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  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 NPI Partnership.

       Section 7.3. Assignees and Substituted Partners

       A. The NPI 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 NPI  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  NPI  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 NPI Partnership,  and otherwise shall
be recognized as effective on the date such  Notification  is filed with the NPI
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  NPI  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  and an  amendment  to this  Agreement
executed by the Managing Partner on its own behalf, as well as on behalf of each
other  Partner,  pursuant to the power of attorney  granted  pursuant to Section
12.5.

       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
purpose of allocating Income,  Investment Income,  Profits,  Losses,  costs, and
Distributable Cash, a Person shall be treated as having become, and as appearing
in the  records of the NPI  Partnership  as, a Partner on such date as the sale,
assignment  or  transfer to such Person was  recognized  by the NPI  Partnership
pursuant to Section 7.3A.

       Section 7.4.  Incapacity of the Limited Partnership

       Upon the  Incapacity of the Limited  Partnership or upon the seizure of a
Limited  Partnership's  Interest in the NPI  Partnership,  the successor to such
Limited Partnership's Interest ("Successor") shall be deemed an assignee of such
Limited  Partnership's  Interest  in the NPI  Partnership  and  neither  the NPI
Partnership nor the Successor shall have the right to demand immediate valuation
and payment of such Limited Partnership's Interest.

                   Dissolution, Liquidation and Termination
                             of the NPI Partnership

       Section 8.1.  Events Causing Dissolution

       A.    The NPI Partnership  shall be dissolved upon the happening of any
of the following events:

             (i) the  expiration of its term,  unless its term shall have been
       extended by the Managing Partner pursuant to Section 2.3;

             (ii) the  Incapacity  of the Managing  Partner.  However,  within
       ninety  days   thereafter   the   remaining   Partners   may  elect  to
       reconstitute   the  NPI   Partnership   prior  to  application  of  the
       liquidation provisions of Section 8.2;

             (iii)  the  Sale  or  other  disposition  at one  time  of all or
       substantially all of the assets of the NPI Partnership  existing at the
       time of such Sale;

             (iv)  the  election  to  dissolve  the NPI  Partnership  (a) by the
       Managing  Partner  (which  election  shall be Consented to by the Limited
       Partnership),  or (b) by the  Consent  of all  Partners  other  than  the
       Managing Partner;

             (v) ninety days after the Removal or withdrawal (unless the Limited
       Partnership  Consents  to a  Successor  pursuant  to Section  6.2) of the
       Managing Partner;

             (vi) the  happening of any other event causing the  dissolution  of
       the  NPI  Partnership  under  the  laws of the  State,  except  that  the
       Incapacity  of any Partner  (other than the Managing  Partner)  shall not
       dissolve  the NPI  Partnership  and the  seizure of the  Interest  of any
       Partner shall not dissolve the NPI Partnership.

<PAGE>




       B.  Dissolution of the NPI  Partnership  shall be effective on the day on
which the event occurs giving rise to the  dissolution,  but the NPI Partnership
shall  not  terminate  until  the  Managing  Partner  has  recorded  a notice of
dissolution of the NPI Partnership in the proper records of any  jurisdiction in
which this  Agreement has been recorded and shall have complied with the laws of
the states in which it does business and the assets of the NPI Partnership  have
been distributed as provided in Section 8.2.

       C. Nothing  contained in this Agreement  shall impair,  restrict or limit
the rights and powers of the Partners under the laws of the State of Oklahoma or
any other  jurisdiction in which the NPI Partnership is doing business to reform
and reconstitute  themselves as a general partnership  following  dissolution of
the NPI Partnership either under provisions  identical to those set forth herein
or under any other provisions.

       Section  8.2.  Liquidation  of the NPI  Partnership;  Liquidation  of a
Partner's Interest

       A. Upon dissolution of the NPI Partnership, its liabilities shall be paid
in the order provided herein.  The Managing  Partner shall either  distribute in
kind or sell the NPI  Partnership's  property so that such disposition is in the
best  interests of the Limited  Partnership,  and shall  execute all  amendments
terminating the NPI Partnership.  In connection with any such Sale, the Managing
Partner shall attempt to obtain the best prices for such property.  Pending such
Sales,  the  Managing  Partner  shall have the right to  continue  to manage and
otherwise  to  deal  with  NPI  Partnership  property.  In  the  event  the  NPI
Partnership is dissolved on account of the Incapacity or Removal of the Managing
Partner,  the NPI 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 NPI Partnership and winding up
its affairs,  and shall pay to such  Liquidating  Agent its reasonable  fees and
expenses  incurred in connection  therewith.  In the event of a distribution  in
kind of any NPI  Partnership  Property  (including  a Net Profits  Interest  and
Royalty), each Partner's Capital Account shall first be credited or debited with
its share of the  unrealized  appreciation  of  depreciation  in the fair market
value of such NPI Partnership 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 the gain or loss on an actual Sale of such
NPI  Partnership  Property.  The Capital  Account of each  Partner to whom a NPI
Partnership  Property is distributed shall be debited with the fair market value
of the NPI Partnership  Property  distributed to it. The Capital Account of each
Partner to whom an  interest in a Producing  Property  is  distributed  shall be
debited  with the fair  market  value of the  interest  distributed  to it.  Any
liquidation  of the NPI  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  NPI
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
