      "Proved Reserves" shall mean those quantities of Hydrocarbons, which, upon
analysis of geologic and engineering data,  appear with reasonable  certainty to
be recoverable in the future from known  Hydrocarbon  reservoirs  under existing
economic  and  operating  conditions.  Proved  reserves  are  limited  to  those
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  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. Proved




                                      -7-
<PAGE>




      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 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.

      "PW Energy" shall mean PW Energy Inc., a Delaware corporation.

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

      "Right of  Presentment"  shall mean the  acquisition  by a purchaser  of a
Limited Partner's Interest pursuant to Section 7.5 of this Agreement.

      "Royalty"  shall mean an interest,  including an overriding  royalty and a
net profits interest,  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 Limited Partnership
of any Limited Partnership Property.

      "Selected  Dealer"  shall mean a member in good  standing of the  National

Manager to offer and sell the Units.

      "State" shall mean the State of Oklahoma.

limited partnership interest are offered and sold pursuant to the Prospectus.

      A. The General Partners, within the authority granted to them under and in
accordance  with  the  provisions  of this  Agreement,  shall  have the full and
exclusive  right to manage and control the  business  and affairs of the Limited
Partnership  and to make all  decisions  regarding  the  business of the Limited

      C. The General Partners'  management authority with respect to significant
Limited Partnership actions shall be exercised jointly by both General Partners,
including without  limitation such actions as the determination of the amount of

Partnership  action delegated to a General Partner under Section  4.lC(iii)) may
be exercised by either  General  Partner  without the  concurrence  of the other
General  Partner,  provided that the General Partner  exercising such management
authority shall, upon inquiry by the other General Partner, notify the inquiring
General Partner of the nature of such actions undertaken without the concurrence
of the inquiring General Partner.  The General Partners shall have the authority
to (i) determine that the "significant"  action specified herein shall no longer
be a  "significant"  action for  purposes of this Section 4.lC and to amend this
Agreement   pursuant  to  Section  l0.lA  of  this  Agreement  to  reflect  such
determination,  (ii) to determine which other Limited Partnership actions, other
than that  specified  herein,  are  "significant"  actions for  purposes of this
Section 4.1C, and (iii) delegate their management  authority to a single General
Partner with

respect to  "significant"  Limited  Partnership  actions at such times and under
such conditions as they may mutually agree upon.

      Limited Partners to the Production  Partnership as required by the Limited
      Partnership's  interest therein, and to execute the Production Partnership
      Agreement  (including any amendment and restatement  thereof) on behalf of
      the Limited Partnership;

              (ii) if the Production Partnership is dissolved, to enter into all

      anything to the contrary contained herein;

              (iii) to maintain the books and records of the Limited Partnership

firm or corporation  dealing with the Limited  Partnership  shall be required to
inquire into the authority of any General 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 a General  Partner as
to its due authorization.

      benefit of any General Partner or Affiliate;

              (ii) neither the General  Partners nor any Affiliate  shall render

              comparable services or selling or leasing comparable equipment and

              Partnership; and

              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  General  Partner  or
              Affiliate or the  competitive  rate which could be obtained in the

Partnership.

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

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

      B. In any threatened,  pending or completed action,  suit or proceeding to
which the General  Partners are a party or are  threatened to be made a party by
reason of the fact that they are the General Partners of the Limited Partnership
(other than an action by or in the right of the Limited  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 of
the Limited  Partnership,  the Limited  Partnership  shall indemnify the General
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 Limited 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 General  Partners did not act
in good faith and in a manner which they  reasonably  believed to be in the best
interests of the Limited Partnership.

      C. In any  threatened,  pending or  completed  action or suit by or in the
right of the Limited  Partnership,  to which the General Partners are a party or
are  threatened  to be made a party,  involving an alleged  cause of action by a
Limited  Partner or Limited  Partners for damages arising from the activities of
the General Partners in the performance of management of the internal affairs of
the Limited  Partnership as prescribed in this Agreement or by law, or both, the
Limited  Partnership  shall  indemnify the General  Partners  against  expenses,
including   attorneys'  fees,  actually  and  reasonably  incurred  by  them  in
connection with the defense or settlement of such action or suit



                                      -24-
<PAGE>




if they acted in good faith and in a manner  they  reasonably  believed to be in
the best interests of the Limited  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  General  Partners'  course  of  conduct  constituted
negligence or misconduct.

      D. To the extent that the General  Partners  have been  successful  on the
merits or otherwise in defense of any action,  suit or proceeding referred to in
Sections 4.1OB or 4.1OC of this Agreement,  or in defense of any claim, issue or
matter  therein,  the  Limited  Partnership  shall  indemnify  them  against the
expenses, including attorneys' fees, actually and reasonably incurred by them in
connection therewith.

      E. Any  indemnification  under Section 4.1OB and 4.1OC of this  Agreement,
unless  ordered by a court,  shall be made by the  Limited  Partnership  only as
authorized in the specific  case and only upon a  determination  by  independent
legal counsel in a written opinion that  indemnification of the General Partners
is proper in the circumstances  because they have met the applicable standard of
conduct set forth in Sections 4.1OB or 4.1OC of this Agreement.

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

      Section 4.11.  Dealer Manager
      -----------------------------

      The Dealer Manager shall have no duties,  responsibilities  or obligations
to the Limited  Partnership,  the General  Partners or any Limited  Partner as a
consequence of its right to receive  Commissions,  except to the extent provided
under the  Securities  Act of 1933,  as  amended.  The  Dealer  Manager  has not
assumed,  and will not assume,  any  responsibility  with respect to the Limited
Partnership  nor will it be  permitted  by the  General  Partners  to assume any
duties, responsibilities or obligations regarding the management,  operations or
any of the business affairs of the Limited Partnership subsequent to the date on
which the Limited Partnership is Activated.

                       Distributions, Fees and Allocations
                       -----------------------------------

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

      A. The Distributable Cash of the Limited  Partnership shall be distributed
simultaneously to the Limited Partners (either directly to such Limited Partners
or as they shall direct by their notice to the General Partners  pursuant to the
reinvestment option set forth in Section 5.lB of this Agreement) and the General
Partners  promptly  upon  receipt  of cash  distributions  from  the  Production
Partnership.  Each Partner's share of each such distribution shall be determined
after giving effect to the allocations set forth in Sections 5.2 and 5.3 of this
Agreement, except that (i) any Distributable Cash attributable to the receipt by
the Production  Partnership  of investment  income (as defined in the Production
Partnership  Agreement)  shall be distributed  100% to the Limited Partners and,
(ii) any  Distributable  Cash  which is  attributable  to a return  pursuant  to
Section 3.4 shall be distributed  entirely to those Limited Partners (other than
corporate  affiliates of Geodyne  Resources,  Inc. or the Dealer  Manager or any
purchasers  of  Units  therefrom  with  respect  to  the  distribution  of  cash
contributed by the Managing Partners to the Production  Partnership  pursuant to
Section  3.4  of  the  Production   Partnership  Agreement  or  to  the  Limited
Partnership  by the General  Partners  pursuant to Section  3.4) who are, at the
time of the distribution,  Limited Partners.  All distributions of Distributable
Cash shall  reduce  dollar-for-dollar  the  balances  of the  Partners'  Capital
Accounts.

        B.

            (i)  Except in North  Carolina  and  Texas,  prior to the first cash
      distribution  by the Limited  Partnership,  each  Limited  Partner will be
      given an  opportunity  to elect to have all or a portion  of such  Limited
      Partner's cash  distributions  (1) paid directly to the Limited Partner in
      cash,  or (2)  held in a  reinvestment  account  established  for  Limited
      Partners of the Limited  Partnership,  any Prior Limited  Partnerships and
      any Subsequent Limited Partnership, any Prior Limited Partnerships and any
      Subsequent  Limited  Partnerships  pending the  reinvestment  of such cash
      distributions in a minimum amount of $100 (with  reinvestment in excess of
      such  minimum  being  permitted  in  whole  increments  of  $100)  in  any
      Subsequent  Limited  Partnership.  After  receipt of the  Prospectus  with
      respect to any Subsequent Limited Partnership, each Limited Partner




                                      -26-
<PAGE>




      may revoke such  Limited  Partner's  prior  election to have such  Limited
      Partner's cash distributions held in the reinvestment  account invested in
      the Subsequent Limited  Partnership.  Such revocation shall be made by the
      Limited Partner's delivery to the Limited  Partnership of a written notice
      of revocation. On or before 30 days prior to the reinvestment of a Limited
      Partner's cash  distributions  in a Subsequent  Limited  Partnership,  the
      General  Partners  shall provide each Limited  Partner who has  previously
      elected to have cash distributions from the Limited Partnership reinvested
      in a Subsequent Limited Partnership,  and who has $100 or more held in the
      reinvestment  account on such  Limited  Partner's  behalf,  a form for the
      Limited Partner to provide the Limited  Partnership such written notice of
      revocation.  The  cash  distributions  of a  Limited  Partner  held in the
      reinvestment  account  shall at all times be the  property  of the Limited
      Partner, and the Limited Partner may withdraw such cash distributions held
      in the reinvestment  account on such Limited  Partner's behalf upon thirty
      days' prior written notice to the Limited  Partnership.  No interest shall
      be payable to Limited  Partners on the amount of their cash  distributions
      held in such reinvestment  account;  provided,  however,  that the General
      Partners  shall hold the  Limited  Partners  harmless  against  any losses
      sustained  therein  and  the  General  Partners  shall  deposit  into  the
      reinvestment  account an amount  equal to any loss  suffered  by a Limited
      Partner prior to the earlier of the time the Limited Partner withdraws the
      Limited  Partner's  share  or  an  investment  in  a  Subsequent   Limited
      Partnership is made on behalf of the Limited Partner.  Prior to investment
      in a Subsequent Limited  Partnership or distribution of such funds, monies
      held in the reinvestment account may be invested in investments  permitted
      under  Section  9.3 of this  Agreement.  Any  costs  and  interest  income
      attributable  to the  maintenance  of the  reinvestment  account  shall be
      charged  or paid,  as the case may be, 50% to PW Energy and 50% to Geodyne
      Properties.

            (ii) Cash distributions  held in the reinvestment  account on behalf
      of a Limited  Partner will be delivered  to such Limited  Partner,  and no
      investment  in a  Subsequent  Limited  Partnership  will  be  made on such
      Limited Partner's behalf,  upon (1) a decision by the General Partners not
      to offer, or continue the offering of, a Subsequent Limited Partnership or
      (2) a  decision  by such  Limited  Partner  not to invest in a  Subsequent
      Limited  Partnership.  Subject to the Limited  Partnership's  receipt of a
      Limited Partner's  written notice of revocation or withdrawal  referred to
      in Section 5.1B(i), amounts held in the reinvestment account




                                      -27-
<PAGE>




      on behalf of a Limited  Partner  which are not  reinvested in a Subsequent
      Limited Partnership (either because such amount is less than $100 or is in
      excess of a whole  increment  of $100) shall  remain in such  reinvestment
      account.

            (iii) A Limited  Partner's cash distribution will be reinvested in a
      Subsequent Limited  Partnership only if a registration  statement covering
      interests in the  Subsequent  Limited  Partnership  is in effect under the
      Securities  act of 1933,  the offering of interests is qualified  for sale
      under the applicable  state  securities laws and the Limited Partner meets
      the appropriate suitability standards.  The General Partners may terminate
      their  offering of interests in a Subsequent  Limited  Partnership  at any
      time and will have no  obligation  to  continue to offer  interests  or to
      permit  reinvestment  of  Distributable  Cash  therein.  In the  event the
      General Partners or their Affiliates offer limited  partnership  interests
      in limited partnerships other than the Subsequent Limited Partnerships and
      provide Limited  Partners the  opportunity to reinvest cash  distributions
      from the Limited Partnership in such limited  partnerships,  the terms and
      conditions  of  such  reinvestment  shall  be  determined  by the  General
      Partners or their  Affiliates in their  discretion  (which may differ from
      the  terms  and   conditions  of   reinvestment   in  Subsequent   Limited
      Partnerships provided herein).

      Section 5.2.  Allocation of Profits and Losses
      ----------------------------------------------

      A. The  Profits  and  Losses and each item of Income,  gain,  loss,  cost,
deduction  and  credit  of the  Limited  Partnership  shall  be  determined  and
allocated with respect to each Fiscal Year of the Limited Partnership as of, and
within 75 days after, the end of such Fiscal Year.

      B. Direct  Administrative Costs and General and Administrative Costs shall
be  allocated  to, and borne by, the  Partners  as  follows:  90% to the Limited
Partners  and 10% to the  General  Partners  prior  to,  and 85% to the  Limited
Partners  and 15% to the  General  Partners  after,  Payout  (as  defined in the
Production Partnership Agreement).

      C. Except as set forth in Section  5.2B,  Profits and Losses and each item
of Income,  gain,  loss, cost,  deduction and credit of the Limited  Partnership
shall be allocated between the Partners and credited to or charged against their
Capital Accounts in the following ratio:




                                      -28-
<PAGE>





       Limited Partners
       (including the General
       Partners to the extent
       they purchase Units)               99%

       Geodyne Properties and
       PW Energy (in the aggregate)        1%

      The General  Partners shall allocate  between  themselves  their aggregate
Interest in a manner such that PW Energy shall be  allocated a percentage  equal
to PW  Production's  percentage  sharing  ratio  in the  Production  Partnership
determined under Section 5.3B(i) of the Production  Partnership  Agreement,  and
the  remaining  amount  shall be allocated  to Geodyne  Properties.  The General
Partners  may amend this  Agreement  to  provide  for any  different  allocation
between themselves at their discretion.

      D. The General  Partners  may not be required to  contribute  funds to the
Limited  Partnership  to pay for Limited  Partnership  costs  allocated  to them
except to the extent necessary to pay costs referred to in Section 5.2B.

      E.  Notwithstanding  anything to the  contrary  that may be  expressed  or
implied in this Agreement, the interest of the General Partners in each material
item of Partnership Income, gain, loss, deduction or credit shall be equal to at
least one  percent of each such item at all times  during the  existence  of the
Partnership. In determining the General Partners' interest in such items for the
purpose of this Section 5.2E, units of limited partnership interest owned by the
General Partners shall not be taken into account.

      Section 5.3.  Determinations of Allocations and Distributions Among
                    Partners
      -------------------------------------------------------------------

      A. Except as set forth in Section 5.lA, all Distributable Cash distributed
to the Limited Partners, as a class, and all Profits and Losses and each item of
Income, gain, loss, cost, deduction or credit allocated to the Limited Partners,
as a class,  shall be  distributed  or  allocated,  as the case may be,  to each
Limited  Partner  in the ratio that the  Capital  Contribution  of such  Limited
Partner bears to the total Capital Contributions of all Limited Partners.




                                      -29-
<PAGE>





      B. Distributable  Cash, Profits and Losses and each item of Income,  gain,
loss, cost,  deduction or credit  distributed or allocated to the Partners shall
be  distributed  or  allocated,  as the case  may be,  to the  Persons  who were
Partners, subject to the provisions of Section 10.2 of this Agreement, 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,
Profits  and Losses and each item of Income,  gain,  loss,  cost,  deduction  or
credit  attributable to the Interest so sold,  assigned or transferred  shall 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 by the
Production  Partnership  shall be distributed to those Partners who are Partners
on the day the  distribution  of such  Distributable  Cash  occurs.  The General
Partners  shall inform the Limited  Partners of the  occurrence and terms of any
such Sale by the Production  Partnership as soon as practicable  after such Sale
has been consummated.

      C.  The  Limited  Partnership's  share  of  the  Production  Partnership's
adjusted basis in each of its Producing  Properties  (allocated  pursuant to the
Managing  Partners'  and  the  Limited  Partnership's  interests  in  Production
Partnership  capital  at the date of  acquisition  of the  respective  Producing
Properties)  shall be allocated  pursuant to Section 613A(c) (7) (D) of the Code
among  the  Partners  in  proportion  to the  interest  of each  in the  Limited
Partnership capital ultimately used to acquire that property.

      D. All items of Income,  gain,  loss,  deduction and credit  allowable for
Federal  income tax purposes and all  recapture of 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 Income from the  Producing
Property is allocated.




                                      -30-
<PAGE>





      E. The Capital  Account of each Partner  shall be credited or debited with
its  Capital  Contribution  and  distributions  of  Distributable  Cash,  by the
adjusted basis of partnership property distributed in kind and with its share of
Income,  gain,  loss,  and  deductions  of the Limited  Partnership.  Solely for
purposes of making  adjustments  to Capital  Accounts,  the Limited  Partnership
shall compute a simulated depletion allowance on each oil and gas property using
that method,  as between the cost depletion  method or the percentage  depletion
method  (without  regard to  limitations  which could apply to less than all the
Partners  such as the quantity  limitations  of Code Section  613A(c)(3))  which
results in the greatest simulated depletion allowance. The Limited Partnership's
simulated depletion allowance shall reduce each Partner's Capital Account in the
same  proportion as such Partner's  share of the adjusted basis of such property
as determined in Section 5.3C above. In no event shall the Limited Partnership's
aggregate simulated  depletion  allowances with respect to a property exceed the
Limited  Partnership's  adjusted basis in such property  (maintained  solely for
Capital  Account  purposes).  Upon  the  taxable  disposition  of all oil or gas
property by the Limited  Partnership,  the  Limited  Partnership's  gain or loss
shall be determined  (solely for Capital  Account  purposes) by subtracting  its
adjusted basis in such property (maintained solely for Capita1 Account purposes)
from the amount  realized from such  disposition.  Any resultant  simulated gain
shall be  allocated  to the  Partners in the same manner as that  portion of the
amount realized from such  disposition  which exceeds the Limited  Partnership's
adjusted basis in such property (maintained solely for Capital Account purposes)
is allocated to the Partners and shall increase such Partners'  Capital Accounts
accordingly.  Any resultant simulated loss shall be allocated to the Partners in
the same  proportion as such Partners (or their  predecessors  in interest) were
allocated  adjusted  basis under  Section 5.3C with respect to such property and
shall reduce such Partners' Capital Accounts accordingly.

      F. The  Capital  Accounts  of those  Partners  which are  charged  with an
expense  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.

                 Non-Transferability of General Partner Interest
                 -----------------------------------------------


      Section 6.1.  Non-Transferability of General Partner Interest
      -------------------------------------------------------------

      Except as  provided  in Section  6.2B,  a General  Partner  (including  by
definition  any successor  General  Partner) shall not have the right to retire,
withdraw, transfer or assign its General Partner Interest, except that there may
be substituted  in its stead as General  Partner any entity that has, by merger,
consolidation or otherwise,  acquired substantially all of its assets or capital
stock and continued its business.

      Section 6.2.  Removal of General Partners
      -----------------------------------------

      A.  Subject to Section  11.3 of this  Agreement,  upon the Consent of more
than 50% in  Interest  (as to capital  and  Profits  and  Losses) of the Limited
Partners

            (i) the power shall be vested in the Limited  Partners to (a) remove
      any or all General Partners and (b) cause the General Partners,  on behalf
      of the Limited Partnership, to Remove any Managing Partner.

            (ii) (a) The power shall be vested in each General Partner to Remove
            the other  General  Partner,  and pursuant to Section  l0.1A of this
            Agreement admit a successor general 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 General  Partner  has been guilty of
            gross negligence, fraud, intentional misconduct or similar breach of
            fiduciary  responsibility  in  carrying  out its duties as a General
            Partner,  or (ii) a General  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 General  Partner for the purpose of  dissolution  or
            liquidation on account of




                                      -32-
<PAGE>




            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 General Partner and
            its consolidated  corporate  affiliates is issued by the independent
            accountants  for such  General  Partner that is qualified on a going
            concern basis, or (b) either General Partner requests an audit to be
            performed  of  the  other  General  Partner  and  its   consolidated
            corporate  affiliates by the  independent  accountants for the other
            General Partner (the expense of such audit being paid by the General
            Partner  requesting  the  audit),  and  such  audit  results  in the
            issuance of an opinion with respect to the  financial  statements of
            the other General 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 General  Partner  is  Removed  by the  Limited
      Partners  or the other  General  Partner,  the Removed  General  Partner's
      Interest  in the Limited  Partnership  shall be  transferred  to the other
      General Partner, and the other General Partner shall assign to the Removed
      General  Partner  a  portion  of  Limited  Partnership  Income,  costs and
      Distributable Cash as and when such items are allocated or distributed, as
      the case  may be,  by the  Limited  Partnership  equal  to the  percentage
      interest of the Removed General Partner in the Limited  Partnership  prior
      to its Removal.

            (ii) If the Limited  Partners elect to Remove a sole General Partner
      as  permitted  under this  Section,  and  further  elect to  continue  the
      business of the Limited  Partnership  with one or more  successor  General
      Partners,  the  removed  General  Partner  shall  not be  Removed  until a
      successor  General  Partner has been selected by the Limited  Partners and
      admitted  to the  Limited  Partnership  pursuant  to Section  10.2 of this
      Agreement.

            (iii) In the  event  the sole  General  Partner  is  Removed  by the
      Limited Partners and a successor  General Partner  selected,  the incoming
      General   Partner  and  the  Removed  General  Partner  shall,  by  mutual
      agreement, select an independent petroleum consultant to value the Removed
      General Partner's Interest in the Limited Partnership.  In determining the
      value of the General 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




                                      -33-
<PAGE>




      factor"  discount  no less than that  utilized  in the most  recent  offer
      extended  pursuant to Section 7.5 of the  Agreement,  if any. The incoming
      General  Partner,  or the  Limited  Partnership,  shall have the option to
      purchase at least 20% of the interests of the Removed  General Partner for
      the value  determined by the  independent  appraisal.  The Removed General
      Partner's Interest in the Limited  Partnership shall be transferred to the
      successor General Partner,  and the successor General Partner shall assign
      to the Removed  General Partner a portion of Limited  Partnership  Income,
      costs and  Distributable  Cash as and when such  items  are  allocated  or
      distributed,  as the case may be, by the Limited  Partnership equal to the
      percentage  interest  of  the  Removed  General  Partner  in  the  Limited
      Partnership prior to Removal,  less the portion purchased by the successor
      General Partner or the Limited Partnership.

            (iv) If the Limited  Partners  have Removed a General  Partner,  the
      power shall be vested in the Limited  Partners to Consent to the admission
      of a successor General Partner meeting the requirements of Section 6.2B(v)
      of this Agreement to take the place of a Removed  General Partner upon the
      consent  of more than 50% in  Interest  (as to  capital  and  Profits  and
      Losses) of the Limited Partners.

            (v) If there is  admitted  to the  Limited  Partnership  a successor
      General  Partner,  such admission  shall not become  effective  unless the
      Limited Partnership shall have received a certificate, duly executed by or
      on behalf of such proposed successor General Partner,  to the effect that:
      (a) it is experienced in performing (or employs  sufficient  personnel who
      are experienced in performing)  functions of the type then being performed
      by the Removed General  Partner and (b) it has a net worth,  together with
      the net worth of any remaining General Partner,  sufficient to satisfy the
      net worth  requirements of the Code,  Treasury  Regulations,  the Internal
      Revenue Service or the courts applicable to a general partner in a limited
      partnership in order to ensure that the Limited  Partnership will not fail
      to be classified for Federal income tax purposes as a partnership.

            (vi) Notwithstanding  Section 3.7B, any General Partner who shall be
      Removed from the Limited  Partnership  shall be released by the  remaining
      General  Partner and any successor  General Partner from all liability for
      Limited  Partnership  debts  and  obligations   incurred  by  the  Limited
      Partnership prior to the time of such Removal.

cause the General Partners,  on behalf of the Limited Partnership,  to terminate
any contracts  between the Managing Partners or any Affiliate and the Production

Partnership,  to select, as the case may be, a replacement  Person therefor upon

      B. In no event  shall all or any part of a Limited  Partner's  Interest be
assigned or transferred to a minor or an incompetent  except in trust or by will
or intestate  succession  or to any Person not  qualified  to hold  interests in

      C. No purported sale,  assignment or transfer by a transferor  after which
the  transferor  would  continue  to hold an  Interest  representing  a  Capital
Contribution of less than $1,000 will be permitted or recognized for any purpose
without the Consent of the General Partners, which Consent shall be granted only
for good cause shown.

      D. No sale,  exchange,  transfer  or  assignment  of a  Limited  Partner's
Interest shall be made if in the opinion of counsel to the Limited  Partnership,
such  sale,  exchange,  transfer  or  assignment,  would (i)  cause the  Limited
Partnership to lose its status as a partnership for Federal income tax purposes,
or (ii) violate the Securities Act of 1933, as amended,  or any state securities
or "blue sky" laws (including any investor  suitability  standard  applicable to
the Limited  Partnership or the Interest to be sold,  exchanged,  transferred or
assigned).

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

      If a Limited  Partner becomes  Incapacitated,  the Person who is its legal
representative shall have all the rights of a Limited Partner for the purpose of
settling  or  managing  its estate and such power as the  Incapacitated  Limited
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  Limited  Partner.  The  Incapacity  of a Limited  Partner shall not
dissolve the Limited Partnership.

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

      A. The  Limited  Partnership  shall  not  recognize  for any  purpose  any
purported sale, assignment or transfer of all or any fraction of the Interest of
a Limited  Partner unless the provisions of Section 7.1 shall have been complied
with and there  shall  have been  filed  with the  Limited  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,



                                      -36-
<PAGE>




assignment  or  transfer  shall be  recognized  by the  Limited  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 Limited
Partnership,  and  otherwise  shall be  recognized as effective on the date such
Notification is filed with the Limited Partnership.

      B. Any Limited  Partner which shall assign all of its Interest shall cease
to be a Limited  Partner,  except that,  unless and until a Substituted  Limited
Partner is admitted in its stead,  such assigning  Limited  Partner shall retain
the statutory rights and obligations of a Limited Partner under the Act.

      C. A Person who is the  assignee of all or any fraction of the Interest of
a Limited  Partner shall be subject to all the  provisions of this Article Seven
to the same  extent and in the same manner as any  Limited  Partner  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  Limited  Partnership  as a
Substituted Limited Partner only with the Consent of the General Partners, which
Consent may be granted or  withheld  by the  General  Partners at their sole and
absolute discretion.

      The admission of such Person as a  substituted  Partner shall be evidenced
by the execution by a General Partner of a certificate  evidencing the admission
of such Person as a Limited Partner and an amendment to this Agreement  executed
by a General  Partner  on its own  behalf,  as well as on  behalf of each  other
Limited  Partner,  pursuant to the power of attorney granted pursuant to Section
12.5 of this Agreement and recorded or filed in the proper records of the State.

      E. No Person shall become a Substituted  Limited Partner until such Person
shall have satisfied the requirements of Section 10.2; provided,  however,  that
for the purpose of allocating Profits,  Losses, and items of income, gain, loss,
cost,  deductions,  credits and Distributable Cash, a Person shall be treated as
having become, and as appearing in the records of the Limited  Partnership as, a
Limited Partner on such date as the sale,  assignment or transfer to such Person
was recognized by the Limited Partnership pursuant to Section 7.3A.




                                      -37-
<PAGE>





      F. Each Limited  Partner  shall  indemnify  and hold  harmless the Limited
Partnership, the General Partners and their Affiliates and every Limited Partner
who was or is a party or is  threatened  to be made a party  to any  threatened,
pending or  completed  action,  suit or  proceeding,  whether  civil,  criminal,
administrative  or  investigative,  by reason of or  arising  from any actual or
alleged  misrepresentation  or  misstatement of facts or omission to state facts
made (or  omitted to be made) by such  Limited  Partner in  connection  with any
assignment,  transfer, encumbrance or other disposition of all or any part of an
Interest,  or the  admission  of a  Substituted  Limited  Partner to the Limited
Partnership,  against  expenses for which the Limited  Partnership or such other
Person has not otherwise been reimbursed  (including attorneys' fees, judgments,
fines and amounts paid in settlement)  actually and reasonably incurred by it in
connection with such action, suit or proceeding.

      G. At the end of each calendar quarter in which (i) a Substituted  Limited
Partner has been  approved for  admission by the General  Partners or (ii) there
has been any return of the Capital  Contributions of the Limited  Partners,  the
General Partners shall file an amended  certificate of limited  partnership with
the  appropriate  authorities  of each  state in which the  Limited  Partnership
transacts business for the purpose of adding as Substituted Limited Partners all
assignees of Interests previously approved by the General Partners for admission
as  Substituted  Limited  Partners  and for  reflecting  accurately  the Capital
Contributions of the Limited Partners.

      H.      (i) Each Limited Partner represents and  warrants that such person
      does not own, directly or indirectly,  more than  20% of  the  outstanding
      stock of the General Partners or any  of their  Affiliates  as  defined in
      Section 1504(a) of the Code.

              (ii) Each Limited Partner further represents and warrants that the
      following  statements  are  true:  (a)  if  such  Limited  Partner  is  an
      individual, such Limited Partner is a U.S. citizen, and is 21 years of age
      or older; if such Limited Partner is a partnership or an association,  all
      of its  members  are of such  citizenship;  if such  Limited  Partner is a
      corporation,  it is  authorized  and otherwise  duly  qualified to hold an
      Interest  in  the  Limited  Partnership;  (b)  such  Limited  Partner  has
      thoroughly  read the  Prospectus and this  Agreement and  understands  the
      nature of the risks involved in the proposed investment;  (c) such Limited
      Partner is  experienced  in  investment  and  business  matters;  (d) such
      Limited  Partner,  or in the case of an IRA or Employee  Benefit  Plan (as
      those terms are defined in the




                                      -38-
<PAGE>




      Prospectus), each beneficiary of such Limited Partner has (x) a net worth,
      exclusive of home, furnishings and automobiles of at least $25,000 and had
      during the last tax year, or estimates that such Limited Partner will have
      during the current year,  "taxable income" as defined in Section 63 of the
      Code, of $25,000 or more (income of $20,000 in  California),  or (y) a net
      worth,  exclusive of home, furnishings and automobiles of at least $90,000
      ($75,000 in California) or (z) satisfies any more restrictive  suitability
      requirements imposed by applicable Blue Sky laws; (e) such Limited Partner
      recognizes that the Limited  Partnership  will be newly organized and will
      have no history of operations  or earnings and is a  speculative  venture;
      (f) such Limited  Partner  understands  that the  transferability  of such
      Limited  Partner's  Interest(s)  in the Limited  Partnership is restricted
      pursuant to the provisions of the Agreement and that such Limited  Partner
      cannot expect to be able to liquidate  such Limited  Partner's  investment
      readily in case of emergency;  and (g) unless otherwise  indicated in such
      Limited  Partner's  Subscription  Agreement  and Power of  Attorney,  such
      Limited  Partner is the sole party in interest in such  Limited  Partner's
      Interest and, as such,  is vested with all legal and  equitable  rights in
      such Interest.

              (iii) In the event that the  General  Partners  believe any of the
      representations  made by a Limited  Partner in Section 7.3H were untrue at
      the time of such Limited  Partner's  acquisition  of an Interest or if the
      General  Partners  believe  any of the  representations  made  in  Section
      7.3H(i)  and (ii)(a)  become  untrue at any time during the time that such
      Limited Partner is a Limited Partner,  the General Partners shall have the
      right,  exercisable  at their  sole  discretion,  within 60 days after the
      receipt of knowledge of such untruth or the recognition of such belief, to
      buy such  Limited  Partner's  Interest  in the  Limited  Partnership  at a
      purchase price calculated in a manner identical to the manner set forth in
      Section  7.5 of this  Agreement.  In the event that the  General  Partners
      believe the  representation  contained in Section  7.3H(ii) (g) has become
      untrue at any time with respect to a Limited Partner, such Limited Partner
      shall immediately file with the General Partners (i) a statement signed by
      the Limited  Partner and the other  interested  parties  setting forth the
      nature  and the  extent of the  interest  of each,  and the  nature of the
      agreement between them, and (ii) such other information,  statements,  and
      grants of powers of attorney as may be requested by the General Partners.




                                      -39-
<PAGE>




      The effective  date of any purchase made pursuant to this Section shall be
the first day of the  calendar  month  during  which the General  Partners  give
notice to the  Limited  Partner  of their  desire to  exercise  their  rights of
purchase hereunder.

      Section 7.4.  Incapacity of a Limited Partner
      ---------------------------------------------
      Upon the Incapacity of a Limited  Partner or upon the seizure of a Limited
Partner's  Interest in the Limited  Partnership,  the  successor to such Limited
Partner's  Interest  ("Successor")  shall be deemed an assignee of such  Limited
Partner's  Interest in the Limited  Partnership  and neither the Limited Partner
nor the Successor shall have the right to demand immediate valuation and payment
of such Limited Partner's Interest.

      Section 7.5.  Right of Presentment
      ----------------------------------

      A. Each Limited  Partner who has subscribed for Units will have the option
subject to the terms and conditions set forth in this Section 7.5 to require the
General  Partners  to purchase  all of such  Limited  Partner's  Interest in the
Limited  Partnership,  provided  that the option may not be exercised  after the
date of any notice that will effect a dissolution and termination of the Limited
Partnership pursuant to Section 8.1 of this Agreement. The obligation of each of
PW Energy and Geodyne  Properties  to purchase  Units shall be joint and several
and shall be limited to an aggregate amount during any four  consecutive  fiscal
quarters equal to 1% of the Limited Partners' Capital  Contributions  (exclusive
of Capital  Contributions  made by either General Partner or an Affiliate in its
capacity  as a  Limited  Partner).  The  obligations  of  the  General  Partners
hereunder  shall be satisfied to the extent an Affiliate of a General Partner or
an partnership  sponsored by the General Partners or their  Affiliates  acquires
tendered Units. A Limited Partner may exercise the Limited Partner's option only
with respect to all of the Limited Partner's  Interest.  Any such exercise shall
be effected by a  Notification  thereof to the  General  Partners.  Prior to the
expiration of twelve months after the date on which 90% of the Limited Partners'
Capital  Contributions  have been expended by the Production  Partnership,  such
latter date being the "Valuation Date," such Limited Partner may, subject to the
terms and conditions of this Section 7.5, sell such Limited  Partner's  Interest
to the  General  Partners at a purchase  price equal to 75% of the  Subscription
amount therefor,  less the amount of any distributions of Distributable  Cash to
such Limited Partner.  Thereafter, each such Limited Partner may, subject to the
terms and conditions of this Section 7.5, tender such Limited Partner's Interest
to the General  Partners for purchase at a price  determined in accordance  with
Section 7.5C of this Agreement.




                                      -40-
<PAGE>





      B. Each  Limited  Partner  tendering  an Interest who does not revoke such
Limited  Partner's  election pursuant to Section 7.5D shall assign such Interest
to the purchaser  thereof  pursuant to the power of attorney granted the General
Partners in the  Subscription  Agreement and Power of Attorney  executed by such
Limited Partner. The purchase price for such Interests will be determined, as of
the close of business of the last day of the calendar  quarter  (the  "Effective
Date"),  with respect to all Interests  tendered to the General  Partners during
each such calendar quarter after the Valuation Date.

      C. The purchase  price to be paid for the Interest of any Limited  Partner
who tenders an Interest  pursuant to this Section 7.5 after the  Valuation  Date
will be determined by assuming the sale of all Production  Partnership  Property
and the subsequent liquidation of the Production Partnership pursuant to Section
8.2 of the Production  Partnership  Agreement and the liquidation of the Limited
Partnership  pursuant to Section 8.2 of this Agreement.  The hypothetical credit
balance in a Limited  Partner's  Capital Account shall be the purchase price for
such Limited Partner's  Interest;  provided,  however,  that such purchase price
shall be reduced by an amount equal to 70% of the distributions of Distributable
Cash received by such Limited  Partner on or before the date the Limited Partner
receives a check in payment for the Limited Partner's tendered Interest which is
attributable  to  sales  of  Production   Partnership   Hydrocarbon   production
attributable  to  Proved  Reserves  since  the date as of which  the  Production
Partnership's  Proved Reserves are calculated for purposes of this Section 7.5C.
In order to value the sale proceeds to be received  upon such assumed sale,  the
General  Partners  shall  employ the  petroleum  engineering  reports  and other
petroleum reserve information  referred to in Section 9.4C of this Agreement for
the end of the Fiscal Year  preceding  the  applicable  Effective  Date.  First,
future gross revenues expected to be derived from the production and sale of the
Proved Reserves attributable to the Production  Partnership Producing Properties
will be  estimated  using  either  (i)  escalations  of future  sales  prices of
Hydrocarbons  supplied by the General  Partners (the  "Escalated  Case") or (ii)
only  escalations  of such future  sales  prices of  Hydrocarbons  permitted  by
Regulation  S-X adopted by the  Securities  and  Exchange  Commission  (the "SEC
Case"), as the General Partners may determine in their discretion.  Next, future
net revenues  will be calculated by deducting  anticipated  expenses  (including
operating  expenses  and other  costs that will be  incurred  in  producing  and
marketing such reserves and any gross  production,  excise,  windfall  profit or
other  taxes,  other  than  Federal  income  taxes,  based  on  the  Hydrocarbon
production of the Production  Partnership  or sales  thereof)  (using either (i)
escalations of future costs supplied


                                      -41-
<PAGE>



by the General  Partners in the event the General Partners adopted the Escalated
Case with respect to future sales prices of Hydrocarbons or (ii) constant future
costs in the event the General  Partners  adopted  the SEC Case with  respect to
future sales prices of Hydrocarbons) from estimated future gross revenues.  Then
the present worth of the future net revenues  will be calculated by  discounting
the  estimated  future  net  revenues  at either  10% (in the event the  General
Partners employed pricing criteria in accordance with the SEC case) or that rate
per annum  which is one (1)  percentage  point  higher  than the  prime  rate of
interest of The Chase  Manhattan Bank, N.A. or any successor bank, as such prime
rate of interest is  announced  by said bank from time to time (in the event the
General  Partners  employed  pricing  criteria in accordance  with the Escalated
Case).  If the latter  interest  rate is used and  exceeds  11% per  annum,  the
General  Partners will provide,  for  comparative  purposes only, the repurchase
price if computed based upon a 10% per annum discount rate.  This amount will be
reduced by an additional 30% to take into account the uncertainties attendant to
the  production  and  sale  of   Hydrocarbon   reserves  and  other   unforeseen
contingencies.  This reduced amount is subject to upward or downward  adjustment
by the General Partners,  in the event that during the period between the end of
the Fiscal Year preceding the applicable Effective Date and such Effective Date,
there has occurred any material increase or decrease in the current price of oil
or gas or in the estimated  amount of  Production  Partnership  Proved  Reserves
thereof  from the current oil and gas prices or the  estimated  Proved  Reserves
used in the above  calculation  of the present worth of the future net revenues.
Salvage  value of tangible  equipment  installed on the  Production  Partnership
Wells and costs of plugging and abandoning the productive Production Partnership
Wells, both discounted at the applicable  aforementioned  rate from the expected
date  of  abandonment,  will be  estimated,  and  the  Production  Partnership's
Producing Properties which do not have Proved Reserves  attributable to them but
which have not been condemned will have such reserves  valued at their then fair
value as determined by an independent petroleum engineering firm. The Production
Partnership's  cash on  hand,  prepaid  expenses,  accounts  receivable  (less a
reasonable  reserve for  doubtful  accounts)  and the market  value of its other
assets as determined by a qualified  independent  appraiser will be added to the
value of the Production  Partnership's Producing Properties thus determined,  to
arrive at the Production  Partnership's  hypothetical sale proceeds for purposes
of this Section 7.5C.




                                      -42-
<PAGE>





      D. Within sixty (60) days after the applicable Effective Date, the General
Partners  will  deliver to each Limited  Partner who has  tendered  such Limited
Partner's Interest to the General Partners during the calendar quarter ending on
such  Effective  Date a check  in the  amount  of the  purchase  price  for such
Interest  together  with  a  statement  evidencing  that  such  price  has  been
determined in accordance with the provisions of Section 7.5C. The statement will
show which  portion of the  purchase  price is  represented  by the value of the
Proved  Reserves  and by each of the other  classes  of  Production  Partnership
assets and liabilities  attributable  to the account of the Limited  Partnership
and,  by virtue of a Limited  Partner's  Interest  in the  Limited  Partnership,
attributable  to the account of the Limited  Partner.  The Limited  Partner will
then have thirty (30) days after  receipt of payment  for such  Interest  from a
General Partner to revoke,  by notice to the General Partners and return of such
check, the sale of such Limited Partner's Interest.  If the Limited Partner does
not timely revoke such Limited  Partner's  intention to sell,  the assignment of
such  Limited  Partner's  Interest to the  purchaser  of such  Interest  will be
executed on such Limited  Partner's  behalf by a General  Partner as attorney in
fact; provided, however, that the obligation of the General Partners to purchase
the Interests  tendered by the Limited Partners shall be limited during any four
consecutive  fiscal  quarters  to an amount  not in excess of 1% of the  Limited
Partners' Capital Contributions  (exclusive of Capital Contributions made by the
General Partners or their Affiliates as Limited Partners). Moreover, the General
Partners  will not be obligated to buy any Units  pursuant to such right if such
purchase,  when added to the total of all other Sales or other  dispositions  of
Interest within the preceding 12 months, would result in the Limited Partnership
being  considered  to have  terminated  within the meaning of Section 708 of the
Internal  Revenue  Code  of  1954,  as  amended,  or  would  cause  the  Limited
Partnership to lose its status as a partnership for Federal income tax purposes.
If  less  than  all of the  Interests  tendered  are  purchased,  the  Interests
purchased will be selected by lot. The Limited Partners whose tendered Interests
were  rejected by reason of the foregoing  limitations  shall not be entitled to
priority in the  following  quarter.  Contemporaneously  with the closing of any
such sale,  which shall not be earlier than 30 days after tender of the purchase
price for an Interest to a Limited Partner,  a General  Partner,  as attorney in
fact for such Limited Partner, will execute such certificates or other documents
and perform such acts as the General  Partners deem necessary to effect the sale
and transfer of the liquidating  Limited Partner's Interest to the purchaser and
to preserve the limited  liability status of the Limited  Partnership  under the
laws of the jurisdictions in which it is doing business.

rights  and  powers  of the  Partners  under  the laws of the State or any other
jurisdiction  in which the Limited  Partnership  is doing business to reform and

or under any other provisions.

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

      A. Upon dissolution of the Limited  Partnership,  its liabilities shall be
paid in the order provided herein.  The General Partners shall either distribute
in kind or sell the Limited  Partnership's  property so that such disposition is
in the best interests of the Limited Partners,  and shall execute all amendments
terminating  the Limited  Partnership.  In  connection  with any such Sale,  the
General  Partners  shall  attempt to obtain the best  prices for such  property.
Pending  such Sales,  the General  Partners  shall have the right to continue to
operate and otherwise to deal with Limited  Partnership  property.  In the event
the Limited  Partnership is dissolved on account of the Incapacity or Removal of
the sole General  Partner,  the Limited  Partnership  shall elect, in accordance
with the provisions of Article  Eleven,  a person (the  "Liquidating  Agent") to
perform  the  function  of a General  Partner in  liquidating  the assets of the
Limited  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 Limited
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 such Partner under Sections 5.2 and 5.3 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 Limited 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



                                      -45-
<PAGE>




      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 5.2 and 5.3 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. No Partner shall be  distributed an
interest in any asset if the  distribution  would result in a deficit balance or
increase  the  deficit   balance  in  its  Capital  Account  (after  making  the
adjustments  referred to in this Section 8.2A relating to distribution in kind).
Any  liquidation  of the Limited  Partnership  shall take place out of court and
without application being made therefor to the Secretary of State of the State.

      B. In  settling  accounts  after  dissolution,  the assets of the  Limited
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 General
Partners and any Liquidating  Agent for any expenses of the Limited  Partnership
paid by or payable  to them to the extent  they are  entitled  to  reimbursement
therefor pursuant to this Agreement; (iii) to all of the Limited Partners in the
amount  equivalent to the amount of their positive  Capital Account balances (as
adjusted   pursuant  to  Section  8.2A  of  this   Agreement)  on  the  date  of
distribution;  (iv) to the  General  Partners  in the amount  equivalent  to the
amount of their  positive  Capital  Account  balances (as  adjusted  pursuant to
Section 8.2A of this Agreement) on the date of distribution; and (v) the balance
shall be paid to the Partners in the manner provided for by Sections 5.2 and 5.3
of this Agreement with respect to Distributable Cash.

      C. In the event that following the final  distribution  under Section 8.2B
the General  Partners have a deficit balance in their Capital Account  balances,
they shall  contribute  cash to the Limited  Partnership  necessary to eliminate
said deficit balance, which amount shall be distributed to the other Partners to
the extent of their remaining positive Capital Account balances.

      D.  Notwithstanding  anything to the contrary in this Agreement,  upon the
dissolution  and  termination  of the  Partnership,  the General  Partners  will
contribute to the Partnership  the lesser of: (a) the deficit  balances in their
capital  accounts;  or (b) the  excess  of 1.01  percent  of the  total  Capital
Contributions of the Limited Partners over the capital previously contributed by
the General Partners.
