       "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;  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.

insufficient to generate cash sufficient to pay such General and  Administrative
Costs in the period in which  they are  incurred  or  accrued or if the  General
Partner,  in its sole  discretion,  elects to defer  payment of such General and
Administrative  Costs (and not charge  interest  thereon  during  such  deferred

Partnership do not exceed the forgoing  limitations,  such unreimbursed  General

distribution  to the Unit Holders or increase the maximum amount of reimbursable

contract   precisely   setting  forth  the  services  to  be  rendered  and  the
compensation to be paid.  Each such contract,  other than this Agreement and the
NPI  Partnership  Agreement,  shall  contain  a  provision  which  shall  permit
termination  of the contract by the Limited  Partnership  without  penalty on 30
days' prior written notice.

       Section 4.9.  Other Operations

        The  General  Partner and its  Affiliates  shall at all times be free to

       B. The General Partner and its Affiliates  shall have no liability to the
Limited  Partnership or to any Unit Holders for any loss suffered by the Limited
Partnership which arises out of any action or inaction of the General Partner or
its  Affiliates  if the  General  Partner  and its  Affiliates,  in good  faith,
determined  that such course of conduct was in the best interests of the Limited
Partnership  and  such  course  of  conduct  did not  constitute  negligence  or
misconduct of the General Partner or its Affiliates. The General Partner and its
Affiliates shall be indemnified by the Limited  Partnership  against any losses,
judgments,  liabilities,  expenses and amounts paid in  settlement of any claims
sustained by it in connection  with the Limited  Partnership,  provided that the
same were not the result of  negligence or misconduct on the part of the General
Partner or its Affiliates.  Any indemnification under this Section 4.10 shall be
satisfied solely out of the assets and Income of the Limited  Partnership and no
Unit Holder or Limited Partner shall have any liability therefor.

any Person acting as a  broker-dealer  shall not be indemnified  for liabilities
arising  under  federal  and state  securities  laws unless (i) 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 (ii) 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 General  Partner shall
apprise the court of the current  published  positions,  if any, of the federal,
Massachusetts   State  Securities   Administrator  and  other  applicable  state
securities administrators regarding indemnification of program sponsors prior to
obtaining court approval of any such indemnification.

       D. The Limited Partnership shall not incur the cost of the portion of any
insurance  which  insures any party against any liability as to which such party
is herein prohibited from being indemnified.

       E. For purposes of this Section 4.10, the term  Affiliates  shall include
only those Affiliates, as defined in Article I, performing services on behalf of
the Limited Partnership.

       Section 4.11.  Dealer Manager

        The Dealer Manager shall have no duties, responsibilities or obligations
to the  Limited  Partnership,  the General  Partner 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  Partner  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 Unit  Holders for the account of the  Depositary  (either
directly  to such Unit  Holders or as they shall  direct by their  notice to the
General Partner pursuant to the  reinvestment  option set forth in Section 5.lB)
and the General Partner promptly upon receipt of cash distributions from the NPI
Partnership.  Subject to Section 9.2B,  Distributable  Cash shall be distributed
99% to the  Depositary  (on behalf of the Unit Holders as a class) and 1% to the
General  Partner  except that (i) any  Distributable  Cash  attributable  to the
receipt by the NPI  Partnership  of  investment  income  (as  defined in the NPI
Partnership Agreement) shall be distributed 100% to the Depositary (on behalf of
the  Unit  Holders  as a  class)  and,  (ii)  any  Distributable  Cash  which is
attributable to a return  pursuant to Section 3.3 shall be distributed  entirely
to those Persons (other than corporate affiliates of Geodyne Resources,  Inc. or
the Dealer Manager or any purchasers of Depositary  Units therefrom with respect
to the  distribution  of cash  contributed  by the  Managing  Partner to the NPI
Partnership  pursuant to Section 3.4 of the NPI Partnership  Agreement or to the
Limited  Partnership  by the  General  Partner  pursuant  to Section 3.4 of this
Agreement) who are, at the time of the distribution, Unit Holders. Distributions
to the Unit Holders  shall be allocated to each Unit Holder  pursuant to Section
5.3. All distributions of Distributable Cash shall reduce  dollar-for-dollar the
balances of the Partners' and Unit Holders' Capital Accounts.

       B.

             (i)  Prior  to  the  first  cash   distribution   by  the   Limited
       Partnership,  each Unit Holder will be given an  opportunity  to elect to
       have all or a portion of such Unit Holder's cash  distributions  (1) paid
       directly  to the  Unit  Holder  in cash,  or (2)  held in a  reinvestment
       account  established  for Unit  Holders of the Limited  Partnership,  any
       Prior  Limited  Partnerships  and  any  Subsequent  Limited  Partnership,
       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 Depositary  Units of any Subsequent  Limited
       Partnership.  After  receipt  of  the  Prospectus  with  respect  to  any
       Subsequent  Limited  Partnership,  each Unit  Holder may revoke such Unit
       Holder's  prior  election to have such Unit Holder's  cash  distributions
       held in the  reinvestment  account  invested in  Depositary  Units of the
       Subsequent Limited Partnership. Such revocation shall be made by the Unit
       Holder's  delivery  to the  Limited  Partnership  of a written  notice of
       revocation.  On or before  30 days  prior to the  reinvestment  of a Unit
       Holder's cash  distributions  in a Subsequent  Limited  Partnership,  the
       General



                                      -21-
<PAGE>



      Partner shall provide each Unit Holder who has previously  elected to have
      cash distributions from the Limited  Partnership  reinvested in Depositary
      Units of a Subsequent Limited  Partnership,  and who has $100 or more held
      in the  reinvestment  account on such Unit Holder's behalf, a form for the
      Unit Holder to provide  the Limited  Partnership  such  written  notice of
      revocation.   The  cash  distributions  of  a  Unit  Holder  held  in  the
      reinvestment  account  shall  at all  times  be the  property  of the Unit
      Holder,  and the Unit Holder may withdraw such cash  distributions held in
      the  reinvestment  account on such Unit Holder's  behalf upon thirty days'
      prior  written  notice to the Limited  Partnership.  No interest  shall be
      payable to Unit Holders on the amount of their cash  distributions held in
      such reinvestment  account;  provided,  however,  that the General Partner
      shall hold the Unit Holders harmless against any losses sustained  therein
      and the General  Partner  shall deposit into the  reinvestment  account an
      amount equal to any loss suffered by a Unit Holder prior to the earlier of
      the  time  the  Unit  Holder  withdraws  the  Unit  Holder's  share  or an
      investment in a Subsequent  Limited  Partnership  is made on behalf of the
      Unit  Holder.  Prior to  investment  in  Depositary  Units of a Subsequent
      Limited  Partnership  or  distribution  of such funds,  monies held in the
      reinvestment  account  may be  invested  in  investments  permitted  under
      Section 10.3 of this Agreement. Any costs and interest income attributable
      to the maintenance of the reinvestment  account shall be paid or credited,
      as the case may be, to the General Partner.

            (ii) Cash distributions  held in the reinvestment  account on behalf
      of a Unit Holder will be delivered to such Unit Holder,  and no investment
      in a Subsequent  Limited  Partnership  will be made on such Unit  Holder's
      behalf,  upon (1) a  decision  by the  General  Partner  not to offer,  or
      continue  the  offering  of,  Depositary  Units  of a  Subsequent  Limited
      Partnership,  (2) a  decision  by such  Unit  Holder  not to  invest  in a
      Subsequent  Limited  Partnership,  or (3) such cash distributions have not
      been invested in a Subsequent  Limited  Partnership within 180 days of the
      date such  distributions  were  initially  deposited  in the  reinvestment
      accounts.  Subject to the Limited Partnership's receipt of a Unit Holder's
      written notice of revocation or withdrawal referred to in Section 5.1B(i),
      amounts held in the reinvestment  account on behalf of a Unit Holder 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 Unit  Holder's  cash  distribution  will be  reinvested  in
      Depositary   Units  of  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
      Depositary  Units  is  qualified  for  sale  under  the  applicable  state
      securities  laws and the Unit  Holder  meets the  appropriate  suitability
      standards.  The General  Partner may  terminate its offering of Depositary
      Units in a  Subsequent  Limited  Partnership  at any time and will have no
      obligation to



                                      -22-
<PAGE>



      continue  to  offer  Depositary   Units  or  to  permit   reinvestment  of
      Distributable  Cash  therein.  In the event  the  General  Partner  or its
      Affiliates offer limited  partnerships  other than the Subsequent  Limited
      Partnerships  and provide Unit Holders the  opportunity  to reinvest  cash
      distributions  from the Limited  Partnership in such  Depositary  Units of
      limited partnerships,  the terms and conditions of such reinvestment shall
      be determined by the General  Partner or its  Affiliates in its discretion
      (which  may  differ  from the  terms and  conditions  of  reinvestment  in
      Depositary Units of Subsequent Limited Partnerships provided herein).

       Section  5.2.  Allocation  of  Income,   Gain,  Loss,  Cost,  Deduction
and Credit

       A. 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 on or before March 15 of each year.

       B.  Direct  Administrative  Costs and General  and  Administrative  Costs
directly  incurred by the Limited  Partnership  shall be allocated to, and borne
by, the  Partners in the same amounts and  proportions  as they would be if such
costs were incurred or borne by only the NPI Partnership.

       C.  Except as set forth in  Sections  5.2B,  5.2F and 5.2G,  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:

       Depositary (on behalf of
       the Unit Holders as a class)  99%
       Geodyne Properties                    1%

       D.  Notwithstanding  anything to the  contrary  that may be  expressed or
implied in this Agreement,  the interest of the General Partner 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 Partner's interest in such items for the
purpose of this Section 5.2D,  Depositary Units or units of limited  partnership
interest owned by the General Partner shall not be taken into account.

       E.  Notwithstanding any other provision of this Agreement,  if, under any
provision of this  Agreement,  the Capital Account of any Partner or Unit Holder
is  adjusted  to  reflect  the  difference  between  the  basis  to the  Limited
Partnership  of  Limited  Partnership  Property  and  such  Limited  Partnership
Property's  fair  market  value,  then all  items of  Income,  gain,  loss,  and
deduction with respect to such Limited  Partnership  Property shall be allocated
among the  Partners  and Unit  Holders so as to take  account  of the  variation
between the basis



                                      -23-
<PAGE>



of such  Limited  Partnership  Property and its fair market value at the time of
the  adjustment  to  such  Partner's  Capital  Account  in  accordancewith   the
requirements of subsection 704(c) of the Code, or in the same manner as provided
under subsection 704(c) of the Code.


       F. Notwithstanding anything to the contrary stated herein,

             (i) There shall be  allocated  to the  General  Partner any item of
       loss,  deduction,  credit or allowance  that,  but for this Section 5.2F,
       would have been allocated to a Unit Holder thereby  causing or increasing
       a deficit balance in such Unit Holder's  Capital Account as of the end of
       the Limited  Partnership's  taxable year to which such allocation related
       (after taking into consideration the provisions of Section 5.3D(v));

             (ii) Any Unit  Holder  who  unexpectedly  receives  an  adjustment,
       allocation or  distribution  specified in Section 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 General Partner  pursuant to clause (i) of this
       Section 5.2F,  the General  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 the
       General Partner pursuant to clause (i) of this Section 5.2F.

       G. Commissions and  Organizational  and Offering Costs shall be allocated
1% to the  General  Partner  and 99% to the  Depositary  (on  behalf of the Unit
Holders as a class), and will be allocated and charged among the Unit Holders as
follows:  (i)  to the  extent  necessary,  to  each  Unit  Holder  in an  amount
sufficient to cause all of the Unit Holders'  Capital Account  balances to be in
the  ratio of the  Depositary  Units  owned by the  Unit  Holders,  and (ii) any
remaining amount pursuant to Section 5.3.

       Section 5.3.  Determinations  of Allocations  and  Distributions  Among
Unit Holders

       A. Except as set forth in Section 5.lA, each item of Income,  gain, loss,
cost,  deduction or credit allocated to the Unit Holders,  as a class,  shall be
allocated  to each Unit  Holder in the ratio that (i) the  number of  Depositary
Units  held of  record by each  Unit  Holder  as of the first day of each  month
during  the  period  ("Record  Date")  bears to (ii)  the  aggregate  number  of
Depositary Units outstanding on each such monthly Record Date.  Distributions of
Distributable Cash for a calendar quarter will be made to Unit Holders of record
on the first day of such  calendar  quarter in the ratio which (i) the number of
Depositary  Units  owned of record by each Unit Holder on such record date bears
to (ii) the aggregate number of Depositary Units



                                      -24-
<PAGE>



outstanding  on such record date.  Unless  otherwise  designated  by the General
Partner,  the record date for  distributions of  Distributable  Cash will be the
last day of the calendar quarter to which such  distributions  are attributable.
Each  distribution  in respect of Depositary  Units shall be paid by the Limited
Partnership only to the Persons who are record holders of Depositary Units as of
the first day of the calendar quarter for which such distribution is being made.
Such  payment  shall  constitute  full payment and  satisfaction  of the Limited
Partnership's  liability in respect of such payment  regardless  of any claim of
any Person who may have an interest in such  payment by reason of an  assignment
or otherwise.

       B. The  Limited  Partnership's  share of the NPI  Partnership's  adjusted
basis in each of its Net Profits Interests and Royalties  (allocated pursuant to
the  Managing  Partner's  and  the  Limited   Partnership's   interests  in  NPI
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 Unit Holders and Partners in proportion to the interest of each in the
Limited Partnership capital ultimately used to acquire that property.

       C. All items of Income,  gain, loss, expense deduction and credit and all
recapture  of such  deductions  and credits  shall be  allocated  and charged or
credited to the Partners and Unit Holders 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 Net Profits  Interest or Royalty shall
be determined at the Partner or Unit Holder level and shall be determined in the
case of percentage  depletion on the same basis that Income from the Net Profits
Interest or Royalty is allocated.

       D. Capital  Accounts shall be established and maintained for each Partner
and Unit Holder 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:

             (i) Each  Partner's or Unit Holder's  Capital  Account shall be (a)
       increased  by the  amount  of cash  contributed  by or on  behalf of such
       Partner or Unit Holder, the fair market value of property  contributed by
       it or on its  behalf  to the  Limited  Partnership  (net  of  liabilities
       securing  such  contributed  property  that the  Limited  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 (b)  decreased  by the amount of  Distributable
       Cash distributed to it, the fair market value of property  distributed to
       it  by  the  Limited  Partnership  (net  of  liabilities   securing  such
       distributed  property  that such Partner or Unit Holder is  considered to
       assume or take subject to under



                                      -25-
<PAGE>



      section  752 of the Code) and  allocations  to it of  Limited  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 Limited  Partnership  Property is distributed to a
      Partner or Unit Holder,  then,  before the Capital Account of such Partner
      or Unit Holder is adjusted as required by clause (i) of this Section 5.3D,
      the Capital Accounts of the Partners and Unit Holders shall be adjusted to
      reflect  the  manner  in  which  the  unrealized  Income,  gain,  loss and
      deduction inherent in such Limited Partnership Property (that has not been
      reflected in such Capital  Accounts  previously)  would be allocated among
      the Partners and Unit Holders if there were a taxable  disposition of such
      Limited  Partnership  Property  for its fair  market  value on the date of
      distribution.

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

            (iv) The  Partners'  and Unit  Holders'  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 or Unit Holders); provided, however,
      that the choice  between  the cost  depletion  method  and the  percentage
      depletion   method   shall   be  made  by  the   General   Partner   on  a
      property-by-property  basis  and  such  choice  shall be  binding  for all
      Limited Partnership taxable years during which such oil or gas property is
      held by the Limited  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' and Unit Holders' Capital
      Accounts in the same  proportions  as the adjusted basis in the particular
      property is allocated  to each  Partner or Unit  Holder.  Upon the taxable
      disposition  of an oil or gas  property  by the Limited  Partnership,  the
      Limited  Partnership's  simulated  gain or loss  shall  be  determined  by
      subtracting its simulated adjusted basis (aggregate  adjusted tax basis of
      the Partners and Unit Holders less simulated depletion allowances) in such
      property from the amount  realized on such  disposition  and the Partners'
      and Unit Holders' 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' and Unit Holders'  allocable
      shares of the total amount realized on such disposition.



                                      -26-
<PAGE>




             (v) For purposes of determining  the Capital Account balance of any
       Partner or Unit Holder as of the end of any Limited  Partnership  taxable
       year for  purposes  of Section  5.2G,  such  Partner's  or Unit  Holder'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 or Unit Holder'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 Limited Partnership, and

                   (b)  Allocations of loss and deduction that, as of the end of
             such year,  reasonably  are  expected to be made to such Partner or
             Unit  Holder  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 or Unit Holder's
             Capital  Account that  reasonably  are expected to occur during (or
             prior  to) the  Limited  Partnership  taxable  years in which  such
             distributions reasonably are expected to be made.

       E. The Capital  Accounts of those  Partners  and Unit  Holders  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.

                                   ARTICLE SIX

                   Withdrawal or Removal of General Partner

       Section 6.1.  Withdrawal of General Partner

        The General  Partner  (including  by definition  any  successor  General
Partner) shall have the right to retire or withdraw,  upon 120 days Notification

assign or transfer its General Partner



                                      -27-
<PAGE>



Interest to a person who shall  become a successor  General  Partner;  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 General Partner.

       Section 6.3.  Removal of General Partner

       A. Subject to Section  12.3,  upon the Consent of the  Depositary,  which
shall  be given if the  Consent  of Unit  Holders  owning  more  than 50% of the
outstanding  Depositary  Units is  obtained,  the  power  shall be vested in the
Depositary to (a) remove the General Partner and (b) cause the General  Partner,
on behalf of the Limited Partnership, to Remove the Managing Partner.

       B. (i) If the Unit  Holders  elect  to  Remove  the  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 Unit Holders and admitted to the
       Limited Partnership pursuant to Section 11.2.

             (ii)  Notwithstanding  Section 3.6B, any General  Partner who shall
       withdraw or be Removed from the Limited  Partnership shall be released by

       debts and obligations  incurred by the Limited  Partnership  prior to the
       time of such Removal.

       6.4 Option to Purchase Interest from Former General Partner

        In the event the General Partner withdraws or is Removed and a successor
General Partner selected, the incoming General Partner and the departing General
Partner shall, by mutual agreement,  select an independent  petroleum consultant
to value the departing General Partner's Interest in the Limited Partnership. If
no  agreement  can be reached on the  selection of a qualified  consultant,  the
departing  General  Partner and incoming  General  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  General Partner.  The incoming  General  Partner,  or the Limited
Partnership,  shall have the option to purchase at least 20% of the interests of
the  departing  General  Partner  for the value  determined  by the  independent
appraisal.  The departing 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  departing  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  departing  General  Partner in the Limited
Partnership  prior to  Removal,  less the  portion  purchased  by the  successor
General Partner or the Limited Partnership.

Partner  meeting  the  requirements  of  Section  6.5B to take the  place of the
departing  General  Partner upon the Consent of the  Depositary,  which shall be

Depositary Units is obtained.

       B. If there is admitted to the Limited  Partnership  a successor  General

General Partner and (ii) it has a net worth  sufficient to satisfy the net worth

individual,  has the authority to become a successor  General  Partner under the
terms of this Agreement;  and (b) the proposed  successor  General Partner shall
have (i) become a party to, and adopted all of the terms and conditions of, this

outstanding  Depositary Units, may elect to reconstitute the Limited Partnership
prior to application of the liquidation provisions of Section 9.2.

       B. Upon the  Incapacity  of the  General  Partner,  the Person who is its
legal  representative  shall  have all the rights of a General  Partner  for the

Partnership,  to terminate  any  contracts  between the Managing  Partner or any

       Assignment of Limited Partner Interests to Unit Holders

       Section 7.1      Assignments of the Interests of the Depositary.

       A. Pursuant to Sections 7.lB and 13.1, the Depositary shall issue to each
Person purchasing one or more Depositary Units a Depositary  Receipt  evidencing
such Depositary Units. The Limited Partnership shall recognize as a Unit Holder,
for the  number  of  Depositary  Units for which  the  Limited  Partnership  has
received  proceeds,  each  Person  to whom the  Depositary  issues a  Depositary
Receipt as of the date  provided  in Section  13.1 or  otherwise  as the General
Partner shall determine in accordance with the provisions of this Agreement.

       B.  The  Depositary,  by the  execution  of this  Agreement,  irrevocably
assigns to the Unit Holders all of the  Depositary's  rights and interest in and
to the  Interests,  except  as  otherwise  provided  herein,  as of the  date of
Activation of the Limited  Partnership.  The rights and interest so  transferred

             (iv) all  rights in respect of  allocations  to Capital  Accounts

             (vi) all  rights to  inspect  books and  records  and to  receive
       reports pursuant to Article Ten;

             (vii) the right to bring derivative actions pursuant to the Act (in
       the event any such action  must be brought in the name of the  Depositary
       as a Limited Partner,  the Depositary agrees to bring such action, at the
       expense of the Unit Holder(s) requesting such action); and



                                      -30-
<PAGE>




           (viii) all rights which  limited  partners  have,  or may have in the
       future,  under this  Agreement or the Act,  except as otherwise  provided
       herein.

       C. The General Partner,  by the execution of this Agreement,  irrevocably
consents  to and  acknowledges  that (i) the  foregoing  assignment  pursuant to
Section 7.1B by the  Depositary to the Unit Holders of the  Depositary's  rights
and  interest  in the  Interests  is  effective  and (ii) the Unit  Holders  are
intended to be  third-party  beneficiaries  of all rights and  privileges of the
Depositary in respect of the Interests. The General Partner covenants and agrees
that,  in  accordance  with  the  foregoing  transfer  and  assignment,  all the
Depositary's  rights and  privileges in respect of Interests may be exercised by
the Unit Holders, including, without limitation, those listed in Section 7.lB.

       D. The Depositary, by execution of this Agreement, irrevocably commits to
exercise its voting rights as the Limited  Partner in accordance with directions
it receives from the Unit Holders such that it will vote a  proportionate  share
of its  Interest  as the owner,  as shown on the books of the  Depositary,  of a
corresponding Depositary Unit shall direct in writing, by proxy or otherwise.

       E. The  Depositary may transfer its Interest as the Depositary to another
Person only with the Consent of the General  Partner and Unit  Holders  owning a
majority of the outstanding Depositary Units.

       F. All  Persons  becoming  Unit  Holders  will by their  payment  for and
acceptance of Depositary Receipts agree to comply with and be bound by the terms
and  conditions of and will be entitled to all rights of Unit Holders under this
Agreement.

       G. Other than pursuant to Sections  7.1B,  7.1E and 7.2, the Depositary
shall  not  transfer,  assign,  encumber,  pledge  or  hypothecate  any of its
Interest.

       Section 7.2  Rights of Unit     Holders

       A. In accordance  with the transfer and  assignment  described in Section
7.1B, it is the intention of the parties hereto that Unit Holders shall have the
same rights and obligations  that Limited Partners have under this Agreement and
under the Act. The fiduciary  duties and  obligations of the General  Partner to
the Limited  Partner under the Act and this  Agreement  shall extend to the Unit
Holders.

       B. Without  limiting the  generality of Section 7.2A,  persons who become
Limited Partners pursuant to Section 7.3 below and Unit Holders shall share pari
passu on the basis of one Limited Partner  Interest for one Depositary Unit, and
shall be  considered  as a single  class,  with respect to all rights to receive
distributions and allocations pursuant to this Agreement.



                                      -31-
<PAGE>




       C. Limited  Partners  (other than the  Depositary) and Unit Holders shall
vote on all  matters in respect of which they are  entitled  to vote  (either in
person, by proxy, or by written  consent),  as a single class, with each Limited
Partner  Interest  and each  Depositary  Unit  entitled  to one vote;  provided,
however, that the Depositary shall vote on behalf of and only as directed by the
Unit Holders.

       Section  7.3.   Conversion  of  Depositary  Units  into  Limited  Partner
Interests.  Subject to the consent of the General Partner,  which consent may be
granted or withheld in its absolute  discretion,  any Unit Holder who desires to
convert his Depositary  Units into an equal number of Limited Partner  Interests
may do so following  Activation of the Limited  Partnership by delivering to the
Depositary  all (but no less  than  all) of his  Depositary  Receipts  (properly
endorsed),  an executed  subscription  agreement and transfer application (which
are available  upon request from the General  Partner),  accompanied  by written
instructions  which  set forth an  intention  to  become a  Substituted  Limited
Partner and request admission as such to the Limited Partnership,  together with
such other instruments or documents as the General Partner or the Depositary may
deem  necessary or desirable,  including the written  acceptance and adoption by
such  Unit  Holder  of the  provisions  of this  Agreement  and  the  execution,
acknowledgment  and  delivery  to the  General  Partner  of a  special  power of
attorney,  the form and  content  of which are  reasonably  satisfactory  to the
General Partner.  Such Depositary  Receipts shall be accompanied by a payment to
the Limited  Partnership  by such Unit Holder of a fee (not to exceed  $100) for
legal and  administrative  costs  and  recording  fees.  Unit  Holders  becoming
Substituted  Limited  Partners  will  be  admitted  to the  Limited  Partnership
quarterly,  or as  promptly  as  possible  after  the  commencement  of the next
calendar  quarter.  Persons who effect such  conversion will receive one Limited
Partner  Interest for each  Depositary Unit they convert and will not be able to
re-exchange  their Limited Partner  Interests for Depositary  Units. The Capital
Account of the  Depositary  shall be reduced by an amount  equal to the  Capital
Account of such  former  Unit  Holder and such  amount  will be  credited as the
former Unit  Holder's  new Capital  Account as a  Substituted  Limited  Partner.
Depositary  Units which have been converted into Limited Partner  Interests will
be cancelled and will not be reissued.  Except as specifically  stated or as the
context  otherwise  requires,  references in all but Articles Seven and Eight of
this Agreement to Unit Holders shall include Substituted Limited Partners and to
Depositary Units shall include Limited Partner Interests of Substituted  Limited
Partners.

                 Transferability of Limited Partner Interests
                              and Depositary Units

       Section  8.1.    Assignments  of  Limited Partner Interests by Limited
 Partners Other than the Depositary.



                                      -32-
<PAGE>




       A.  Subject to the  provisions  of Section  8.6, no  Substituted  Limited
Partner may assign,  sell or transfer his Limited Partner  Interests without the
approval  of the General  Partner.  In  exercising  its  obligations  under this
Section 8.1A,  the General  Partner shall use its best effort to ensure that the
terms of transfer  are not in  contravention  of any of the  provisions  of this
Agreement and shall not approve any transfer:

             (i)   to a Person who makes a market in the  Depositary  Units or
       Limited Partner Interests;

             (ii)  which  is  effected  through  a  matching  agent  unless  the
       procedures  of such  matching  agent  with  respect  to the  transfer  of
       Depositary  Units or Limited Partner  Interests have been approved by the
       General  Partner  as not  being  incident  to a  public  trading  of such
       securities within the meaning of Code Sections 7704, 469(k) or 512(c);

             (iii) if such sale,  assignment,  transfer or exchange  would be in
       violation of any applicable  federal or state  securities laws (including
       any  applicable  suitability  standard  and, with respect to transfers by
       residents of California,  the  restrictions on transfer set forth in Rule
       260.l41.11 of Title 10 of the  California  Administrative  Code) or would
       cause  the  Limited  Partnership  to be taxed as an entity  other  than a
       partnership under the Code;

             (iv)  except for  transfers  by gift or  inheritance,  intra-family
       transfers,  transfers  resulting from family  dissolutions,  transfers to
       Affiliates or transfers of such transferor's  entire remaining holding of
       Limited  Partner  Interests,  if the  transferor  would hold less than 10
       Limited Partner Interests.

       B. Any attempted sale, assignment,  transfer or exchange in contravention
of the provisions of this Section 8.1 shall, unless otherwise  determined by the
General Partner in its sole discretion, be void and deemed ineffectual and shall
not bind or be recognized by the Limited Partnership.

       C. The Limited  Partnership  need not recognize for any purpose any sale,
assignment or transfer of the Limited Partner Interests of a Substituted Limited
Partner  unless  there  shall have been filed with the Limited  Partnership  and
recorded on the Limited  Partnership's  books a duly  executed and  acknowledged
instrument of assignment,  and such instrument  evidences the written acceptance
by the assignee of all of the terms and provisions of this Agreement, represents
that  such  assignment  was  made in  accordance  with all  applicable  laws and
regulations  and in all other respects is  satisfactory in form and substance to
the General Partner.



                                      -33-
<PAGE>




       D. The  Partnership  shall not  recognize  for any purpose any  purported
sale,  assignment  or  transfer  of all or part  of the  Interest  of a  Limited
Partner, and such purported sale,  assignment or transfer shall be null and void
if, in the opinion of counsel:

             (i) such sale,  transfer,  assignment  or transfer  would cause the
       Limited  Partnership  to  be  treated  as  an  association  taxable  as a
       corporation  for federal  income tax purposes or, when added to the total
       of all other sales or  exchanges  or  Interests  within the  preceding 12
       months,  would result in the Limited Partnership being considered to have
       terminated within the meaning of Section 708 of the Code; and the General
       Partner is expressly  authorized to enforce this  provision by suspending
       transfers  if and when any such  transfer  would  result in  transfers of
       Interests in the Limited Partnership which represent in the aggregate 40%
       or more of all Interests;

             (ii) such sale,  transfer  or  assignment  would  violate any state
       securities  or "blue  sky" laws  (including  any  applicable  suitability
       standards)  applicable to the Limited  Partnership  or the Interest to be
       transferred  or assigned,  except in the case of transfers upon the death
       of the Limited  Partner (by bequest or  inheritance)  or by  operation of
       law; or

             (iii) such sale,  transfer  or  assignment  might cause the Limited
       Partnership to be classified as a publicly traded  partnership within the
       meaning of Code Sections 7702 469(k) or 512(c).

       E. Unless otherwise provided by the General Partner, any sale, assignment
or transfer of a Substituted  Limited Partner's  Interest shall be recognized by
the Limited  Partnership as of the first business day of the month following the
approval of such  assignment  or transfer  by the  General  Partner,  or as soon
thereafter  as  practicable.  The  General  Partner  shall  not  approve  sales,
assignments or transfers  more  frequently  than quarterly  unless it receives a
written opinion of counsel that more frequent approvals shall not jeopardize the
Limited  Partnership's  federal income tax status as a partnership.  The Limited
Partnership  and the General  Partner shall be entitled to treat the assignor of
such Limited  Partner  Interests as the absolute  owner thereof in all respects,
and shall incur no liability for any allocation of Profit or Loss, distribution,
or  transmittal  of reports or notice  required to be given to Limited  Partners
hereunder  which is made in good faith to such  assignor  until such time as the
written  instrument of assignment  has been received by the Limited  Partnership
and recorded on its books.

       F. The General Partner may reasonably interpret, and is hereby authorized
to take such action as it deems necessary or desirable to effect,  the foregoing
provisions  of this  Section 8.1.  The General  Partner  may, in its  reasonable
discretion,  and without the  approval of the Limited  Partner or Unit  Holders,
amend the  provisions  of this  Agreement  in such manner as may be necessary or
desirable to (i)



                                      -34-
<PAGE>



preserve  the tax status of the Limited  Partnership  as a  partnership  or (ii)
avoid  a  classification  of  the  Limited  Partnership  as  a  publicly  traded
partnership  within the meaning of Code  Sections  7704,  469(k) or 512(c).  The
General Partner may, in its reasonable  discretion,  and without the approval of
the  Limited  Partners  or Unit  Holders,  also  amend  the  provisions  of this
Agreement to include  provisions  governing the  transferability of Interests in
the Limited  Partnership which may be approved in future  legislation,  Treasury
Regulations,   administrative  rulings  and  other  pronouncements  or  judicial
decisions.

       G. No  purported  sale,  assignment  or  transfer by a  transferor  of an
Interest shall be recognized  unless (i) the transferor  shall have  represented
that such transfer (x) was effected  through a  broker-dealer  or matching agent
whose procedures with respect to the transfer of Interests have been approved by
the General  Partner as not being  incident to a public  trading  market and not
through any other  broker-dealer  or  matching  agent or (y)  otherwise  was not
effected  through a  broker-dealer  or  matching  agent  which makes a market in
Interests or which provides a readily available, regular and ongoing opportunity
to holders of Interests  to sell or exchange  their  Interests  through a public
means of obtaining or providing  information  of offers to buy, sell or exchange
Interests and (ii) the General Partner determines that such sale,  assignment or
transfer  would not, by itself or together  with any other  sales,  transfers or
assignments,  likely result in the Limited  Partnership's  being classified as a
publicly-traded partnership.

       Section 8.2.  Substituted Limited Partners.

       A. The  consent  of the  General  Partner  shall be  required  before the
assignee  of any Limited  Partner  Interest  shall be admitted as a  Substituted
Limited  Partner,  which  consent  may be  withheld  in the  sole  and  absolute
discretion of the General Partner.

       B. No  person  shall  have the right to  become a  Substituted  Limited
Partner in place of his assignor  unless all of the following  conditions  are
first satisfied:

             (i)  a  duly  executed  and  acknowledged   written  instrument  of
       assignment  complying  with  Section  8.1 shall  have been filed with the
       Limited  Partnership and recorded on its books,  which  instrument  shall
       specify the Limited  Partner  Interests  being assigned and set forth the
       intention of the assignor  that the  assignee  succeed to the  assignor's
       interest as a Substituted Limited Partner in his place;

             (ii) the  transferor  and his  assignee  shall  have  executed  and
       acknowledged  such other  instruments  as the  General  Partner  may deem
       necessary or desirable to effect such substitution, including the written
       acceptance  and  adoption  by the  assignee  of the  provisions  of  this
       Agreement, as the same may be amended, and his execution,  acknowledgment
       and delivery to the General  Partner of a special power of attorney,  the
       form and  content of which are  reasonably  satisfactory  to the  General
       Partner; and



                                      -35-
<PAGE>




             (iii) a transfer fee  sufficient to cover all  reasonable  expenses
       connected with such substitution (not to exceed $50) shall have been paid
       to the Limited Partnership.

       C. By  executing or adopting  this  Agreement,  each Limited  Partner and
Substituted Limited Partner and, by the purchase of a Depositary Unit, each Unit
Holder hereby consents to the admission of Substituted  Limited  Partners by the
General Partner in accordance with the foregoing.

       D. The  General  Partner  shall amend this  Agreement  at least once each
quarter if necessary to effect the substitution of Substituted Limited Partners.

       Section 8.3  Transferability of Depositary Units.

       A.  Depositary  Units  may  be  transferred  only  as  provided  in  this
Agreement.  The Depositary Units shall be evidenced by Depositary Receipts which
shall be issued in registered form only and shall be transferable subject to the
same  restrictions  and  conditions  applicable to transfers of Limited  Partner
Interests  set forth in Section 8.1 above.  The  Depositary  shall not recognize
transfers  of  Depositary  Units  except by a transfer  of  Depositary  Receipts
therefor.  Unit Holders who are residents of the State of  California  must meet
the  restrictions  on transfers set forth in Rule  260.14l.11 of Title 10 of the
California  Administrative  Code. Except as provided in Section 8.4, no transfer
of  Depositary  Receipts  will  be  recorded  or  otherwise  recognized  by  the
Depositary or Limited  Partnership for any purpose  whatsoever  unless and until
the transferee has certified to the Depositary  that he is an Eligible  Investor
and,  unless  the  transfer  is among  members  of the  immediate  family of the
transferor Unit Holder,  paid a transfer fee to reimburse the Depositary for all
actual,  reasonable and necessary  expenses (not to exceed $50 per  transaction)
incurred in connection with the transfer.

       B. A transferee who has accepted  delivery of a Depositary  Receipt shall
be  deemed to have  agreed  to comply  with and be bound by all of the terms and
conditions of this Agreement.

       Section 8.4 Eligible Investors.  If the General Partner determines that a
Unit Holder or Substituted  Limited Partner is not an Eligible Investor (i) then
the Unit  Holder  shall  immediately  be  divested  of his  rights to Consent on
matters submitted to Unit Holders and Substituted  Limited Partners (and no such
Depositary  Units shall be  Consented  by the  Depositary  or  otherwise  deemed
outstanding for purposes of Consents of Unit Holders under this Agreement),  and
(ii) if such Person is subject to a higher rate of windfall profits tax than the
rate imposed  upon other Unit  Holders and  Substituted  Limited  Partners,  the
General Partner shall adjust actual cash distributions payable to such Person in
order to reflect  accurately  any varying rate of windfall  profits tax imposed.
Any amounts so  withheld  shall be deemed to have been  distributed  and the tax
shall be treated as paid by the Person.

       Section  8.5  Death,  Incompetency  or  Dissolution  of  a  Substituted
Limited Partner or Unit Holder.

        If a  Substituted  Limited  Partner or Unit Holder who is an  individual
dies or a court of  competent  jurisdiction  adjudges him to be  incompetent  to
manage his person or his property,  such Substituted Limited Partner's executor,
administrator,  guardian, conservator or other legal representative may exercise
all of such  Substituted  Limited  Partner's  or Unit  Holder's  rights  for the
purpose of settling his estate or  administering  his  property,  including  any
power  under this  Agreement  of an  assignee  to become a  Substituted  Limited
Partner or Unit Holder.  If a  Substituted  Limited  Partner or Unit Holder is a
corporation, trust or other entity and is dissolved or terminated, the powers of
such  Substituted  Limited  Partner or Unit Holder may be exercised by its legal
representative or successor.

                           of the Limited Partnership

       Section 9.1.  Events Causing Dissolution

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

             (i) the expiration of its term, without any continuation  thereof
       as set forth in Section 2.3;

             (ii) the  Incapacity  of the  General  Partner.  However,  within
       ninety days thereafter the Unit Holders may elect to  reconstitute  the

       shall not dissolve the Limited Partnership.

       B. Dissolution of the Limited  Partnership  shall be effective on the day
on which  the event  occurs  giving  rise to the  dissolution,  but the  Limited
Partnership  shall not terminate until the General Partner has recorded a notice
of  dissolution of the Limited  Partnership  with the office of the Secretary of
State of the State and shall have  complied with the laws of the other states in
which its does  business  and the assets of the  Limited  Partnership  have been

       Section 9.2.  Liquidation

       A. Upon dissolution of the Limited Partnership,  its liabilities shall be
paid in the order provided  herein.  The General  Partner shall sell the Limited
Partnership's  property so that such disposition is in the best interests of the
Unit  Holders,  and  shall  execute  all  amendments   terminating  the  Limited
Partnership. In connection with any such Sale, the General Partner shall attempt
to obtain the best prices for such  property.  Pending  such Sales,  the General
Partner  shall have the right to continue to operate and  otherwise to deal with
Limited Partnership property. In the event the Limited Partnership is



                                      -38-
<PAGE>



dissolved on account of the  Incapacity or Removal of the General  Partner,  the
Limited  Partnership  shall elect,  in accordance with the provisions of Article
Twelve,  a person  (the  "Liquidating  Agent") to perform  the  function  of the
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  or
Unit Holder's  Capital  Account to the extent  allocable to such Partner or Unit
Holder under Sections 5.2 and 5.3. 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.

       The  Liquidating  Agent shall agree not to resign at any time  without 15
days'  prior  written  notice and (if other  than the  General  Partner)  may be
removed at any time,  with or without  cause,  by notice of removal  approved by
Unit  Holders  owning a  majority  of the  outstanding  Depositary  Units.  Upon
dissolution,  removal,  or resignation of the Liquidating Agent, a successor and
substitute  Liquidating Agent (who shall have and succeed to all rights,  powers
and duties of the original  Liquidating Agent) shall, within 30 days thereafter,
be selected by Unit  Holders  owning a majority  of the  outstanding  Depositary
Units. The right to appoint a successor or substitute  Liquidating  Agent in the
manner  provided  herein shall be recurring  and  continuing  for so long as the
functions and services of the Liquidating Agent are authorized to continue under
the provisions hereof, and every reference herein to the Liquidating Agent shall
be deemed  to refer  also to any such  successor  substitute  Liquidating  Agent
appointed in the manner herein  provided.  The Liquidating  Agent shall have and
may exercise,  without  further  authorization  or Consent of any of the parties
hereto,  all of the powers conferred upon the General Partner under the terms of
this Agreement (but subject to all of the  applicable  limitations,  contractual
and  otherwise,  upon the exercise of such powers,  other than the limitation on
sales set forth in Section  4.5B) to the extent  necessary  or  desirable in the
good  faith  judgment  of the  Liquidating  Agent to carry  out the  duties  and
functions of the Liquidating  Agent hereunder for and during such period of time
as shall be reasonably  required in the good faith  judgment of the  Liquidating
Agent to complete the winding-up and  liquidation of the Limited  Partnership as
provided for herein.

       Notwithstanding   the  provision  of  Section  9.1  which   requires  the
liquidation of the assets of the Limited  Partnership,  but subject to the order
or priorities set forth herein, if on dissolution of the Limited Partnership the
General Partner or Liquidating  Agent  determines that an immediate sale of part
or all of the Limited Partnership's assets would be impracticable or would cause
undue loss to the Unit Holders, the General Partner or Liquidating Agent may, in
its absolute  discretion,  defer for a reasonable  time the  liquidation  of any
assets except those necessary to satisfy  liabilities of the Limited Partnership
(other than those to Partners).

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
Partner 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 Unit  Holders in the
amount  equivalent to the amount of their positive  Capital Account balances (as
adjusted  pursuant  to Section  9.2A) on the date of  distribution;  (iv) to the
General Partner in the amount  equivalent to the amount of its positive  Capital
Account  balance  (as  adjusted  pursuant  to  Section  9.2A)  on  the  date  of
distribution;  and (v) the  balance,  if any,  shall be paid to the Partners and
Unit Holders in the manner in which Income is then being allocated.

       C. If the General  Partner has a deficit  balance in its Capital  Account
following the distribution(s)  provided for in Section 9.2B above, as determined
after taking into account all adjustments to its Capital Account for the taxable
year of the Limited  Partnership  during which such  distribution(s)  occur,  it
shall  restore the amount of such  deficit  balance to the  Limited  Partnership
within 90 days and such amount shall be  distributed  to the other  Partners and
Unit Holders in accordance with their positive Capital Account balances.

       D. Notwithstanding  anything to the contrary in this Agreement,  upon the
dissolution  and  termination  of the  Partnership,  the  General  Partner  will
contribute  to the  Partnership  the lesser of: (a) the  deficit  balance in its
capital  account;  or (b)  the  excess  of 1.01  percent  of the  total  Capital
Contribution  of the Depositary over the capital  previously  contributed by the
General Partner.

a material adverse effect upon the Unit Holders. Amendments to this Agreement to

Unit  Holders,  with the views,  if any, of the General  Partner with respect to
such proposed  amendment,  unless the General Partner has received prior thereto

will impair the limited liability of the Unit Holders,  or will adversely affect
the  classification  of the Limited  Partnership  as a  partnership  for federal
income tax purposes.


       B.  Amendments to this Agreement  shall be adopted if: (i) in the case of
amendments  other  than  those  referred  to in  Section  11.2,  the  conditions

signed  writing  directing the manner in which it desires that its vote be cast,
which writing must be received by the General Partner prior to such meeting,  or
(ii) without a meeting,  by a signed  writing  directing  the manner in which it
desires that its vote be cast,  which writing must be received by the Depositary

        The General  Partner may at any time call a meeting of the Unit  Holders
or for a vote, without a meeting,  of the Unit Holders on matters upon which the

meeting or vote upon receipt by the General  Partner of a request  therefor made

Limited Partnership or counsel designated by Unit Holders owning at least 10% of
the  outstanding  Depositary  Units delivers to the Depositary an opinion to the
effect that the grant or the exercise of those powers is  prohibited by the Act,
will impair the limited  liability of the Depositary or the Unit Holders or will
affect the  classification  of the  Limited  Partnership  as a  partnership  for
Federal income tax purposes.

       Section  12.4.  Submissions to Unit Holders

        The General Partner shall give all the Unit Holders  Notification of any
