                                   (Unaudited)




1.    ACCOUNTING POLICIES
      -------------------

      The combined balance sheets as of March 31, 2000,  combined  statements of
      operations  for the  three  months  ended  March 31,  2000 and  1999,  and
      combined  statements  of cash flows for the three  months  ended March 31,
      2000 and 1999 have been prepared by Geodyne  Resources,  Inc., the General
      Partner  of  the  Geodyne   Institutional/Pension  Energy  Income  Limited
      Partnerships, without audit. Each limited partnership is a general partner
      in the related Geodyne NPI Partnership (the "NPI  Partnerships")  in which
      Geodyne Resources,  Inc. serves as the managing partner.  For the purposes
      of these financial  statements,  the general partner and managing  partner
      are  collectively  referred to as the  "General  Partner"  and the limited
      partnerships  and NPI  Partnerships  are  collectively  referred to as the
      "Partnerships".  In the opinion of  management  the  financial  statements
      referred to above include all necessary adjustments,  consisting of normal
      recurring  adjustments,  to present fairly the combined financial position
      at March 31, 2000, the combined results of operations for the three months
      ended March 31, 2000 and 1999,  and the combined  cash flows for the three
      months ended March 31, 2000 and 1999.

      Information  and  footnote  disclosures  normally  included  in  financial
      statements  prepared in  accordance  with  generally  accepted  accounting
      principles  have been  condensed  or  omitted.  The  accompanying  interim
      financial  statements should be read in conjunction with the Partnerships'
      Annual Report on Form 10-K filed for the year ended December 31, 1999. The
      results  of  operations  for the  period  ended  March  31,  2000  are not
      necessarily indicative of the results to be expected for the full year.

      As used in these financial  statements,  the Partnerships' net profits and
      royalty  interests in oil and gas sales are  referred to as "Net  Profits"
      and the  Partnerships'  net profits and royalty  interests  in oil and gas
      properties  are  referred  to as  "Net  Profits  Interests".  The  working
      interests from which the  Partnerships'  Net Profits  Interests are carved
      are referred to as "Working Interests".

      The Limited  Partners' net income or loss per unit is based upon each $100
      initial capital contribution.




                                      -20-





      NET PROFITS INTERESTS
      ---------------------

      The  Partnerships  follow the successful  efforts method of accounting for
      their Net Profits Interests.  Under the successful efforts method, the NPI
      Partnerships  capitalize all acquisition costs. Property acquisition costs
      include  costs  incurred by the  Partnerships  or the  General  Partner to
      acquire  producing  properties,   including  related  title  insurance  or
      examination costs,  commissions,  engineering,  legal and accounting fees,
      and similar costs directly related to the acquisitions,  plus an allocated
      portion,   of  the  General  Partner's   property   screening  costs.  The
      acquisition cost to the NPI Partnership of Net Profits Interests  acquired
      by the General  Partner is  adjusted  to reflect  the net cash  results of
      operations,  including  interest incurred to finance the acquisition,  for
      the period of time the properties are held by the General Partner prior to
      their transfer to the Partnerships. Impairment of Net Profits Interests is
      recognized based upon an individual property assessment.

      Depletion  of the  costs  of Net  Profits  Interests  is  computed  on the
      unit-of-production  method. The Partnerships'  calculation of depletion of
      its Net Profits Interests includes estimated dismantlement and abandonment
      costs, net of estimated salvage value.

      The  Partnerships  do  not  directly  bear  capital  costs.  However,  the
      Partnerships  indirectly bear certain capital costs incurred by the owners
      of the  Working  Interests  to the extent such  capital  costs are charged
      against the applicable oil and gas revenues in calculating the Net Profits
      payable to the Partnerships.  For financial  reporting purposes only, such
      capital costs are reported as capital  expenditures  in the  Partnerships'
      Statements of Cash Flows.


2.    TRANSACTIONS WITH RELATED PARTIES
      ---------------------------------

      The Partnerships'  partnership agreements provide for reimbursement to the
      General Partner for all direct general and administrative expenses and for
      the general and  administrative  overhead  applicable to the  Partnerships
      based on an allocation of actual costs  incurred.  During the three months
      ended  March 31,  2000 the  following  payments  were made to the  General
      Partner or its affiliates by the Partnerships:

              P-6                13,468               37,641

      Affiliates  of the  Partnerships  operate  certain  of  the  Partnerships'
      properties and their policy is to bill the  Partnerships for all customary
      charges and cost reimbursements associated with their activities.

      The receivable from the General Partner at March 31, 2000 for the P-1, P-2
      and P-3 Partnerships  represents proceeds due to the Partnerships from the
      sale of oil and gas  properties to third parties  during the first quarter
      of 2000.  Subsequent to March 31, 2000,  this  receivable was collected by
      the Partnerships.

ITEM 2.    MANAGEMENT'S  DISCUSSION  AND  ANALYSIS OF FINANCIAL  CONDITION  AND
           RESULTS OF OPERATIONS


USE OF FORWARD-LOOKING STATEMENTS AND ESTIMATES
- -----------------------------------------------

      This Quarterly Report contains  certain  forward-looking  statements.  The
      words "anticipate",  "believe",  "expect",  "plan", "intend",  "estimate",
      "project", "could", "may" and similar expressions are intended to identify
      forward-looking  statements.  Such statements reflect management's current
      views  with  respect  to future  events and  financial  performance.  This
      Quarterly Report also includes certain information,  which is, or is based
      upon,  estimates  and  assumptions.  Such  estimates and  assumptions  are
      management's  efforts to accurately reflect the condition and operation of
      the Partnerships.

      Use of  forward-looking  statements and estimates and assumptions  involve
      risks  and  uncertainties  which  include,  but are not  limited  to,  the
      volatility of oil and gas prices, the uncertainty of reserve  information,
      the operating risk associated  with oil and gas properties  (including the
      risk of personal injury,  death,  property  damage,  damage to the well or
      producing  reservoir,  environmental  contamination,  and other  operating
      risks), the prospect of changing tax and regulatory laws, the availability
      and capacity of  processing  and  transportation  facilities,  the general
      economic climate,  the supply and price of foreign imports of oil and gas,
      the level of consumer  product demand,  and the price and  availability of
      alternative  fuels.  Should  one or more of these  risks or  uncertainties
      occur or should  estimates  or  underlying  assumptions  prove  incorrect,
      actual  conditions or results may vary materially and adversely from those
      stated, anticipated, believed, estimated, and otherwise indicated.


GENERAL
- -------

      The  Partnerships  are engaged in the  business of  acquiring  Net Profits
      Interests in producing oil and gas properties  located in the  continental
      United States.  In general,  a Partnership  acquired passive  interests in
      producing  properties and does not directly engage in development drilling
      or  enhanced  recovery  projects.  Therefore,  the  economic  life of each
      limited  partnership,  and its related NPI Partnership,  is limited to the
      period  of  time  required  to  fully  produce  its  acquired  oil and gas
      reserves. A Net Profits Interest entitles the Partnerships to a portion of
      the  oil  and  gas  sales  less  operating  and  production  expenses  and
      development costs generated by the owner of the



                                      -23-




      underlying  Working  Interests.  The net  proceeds  from  the oil and gas
      operations  are  distributed  to the  Limited  Partners  and the  General
      Partner in  accordance  with the terms of the  Partnerships'  partnership
      agreements.


LIQUIDITY AND CAPITAL RESOURCES
- -------------------------------

      The Partnerships began operations and investors were assigned their rights
      as Limited Partners,  having made capital contributions in the amounts and
      on the dates set forth below:

                                                     Limited
                                Date of          Partner Capital
            Partnership       Activation          Contributions
            -----------    ------------------    ---------------

               P-1         October 25, 1988        $10,807,400
               P-2         February 9, 1989          9,009,400
               P-3         May 10, 1989             16,963,700
               P-4         November 21, 1989        12,630,600
               P-5         February 27, 1990        11,844,900
               P-6         September 5, 1990        14,304,100

      In general,  the amount of funds  available for  acquisition  of producing
      properties was equal to the capital contributions of the Limited Partners,
      less 15% for sales  commissions and  organization and management fees. All
      of the Partnerships have fully invested their capital contributions.

      Net proceeds from the  Partnerships'  Net Profits Interests less necessary
      operating  capital are distributed to the Limited  Partners on a quarterly
      basis.  Revenues and net proceeds of a Partnership  are largely  dependent
      upon the volumes of oil and gas sold and the prices  received for such oil
      and gas. While the General  Partner cannot predict future pricing  trends,
      it believes the working capital available as of March 31, 2000 and the net
      revenue generated from future operations will provide  sufficient  working
      capital to meet current and future obligations.

      During  the three  months  ended  March  31,  2000,  capital  expenditures
      indirectly  incurred  by  the  P-6  Partnership  totaled  $37,129.   These
      expenditures   were   primarily   due   to  the   Partnership's   indirect
      participation  in the  recompletion  of the  Myron No. 2 well  located  in
      Grayson County, Texas in order to improve the recovery of reserves.




                                      -24-





RESULTS OF OPERATIONS
- ---------------------

      GENERAL DISCUSSION

      The following  general  discussion  should be read in conjunction with the
      analysis  of results of  operations  provided  below.  The most  important
      variables affecting the Partnerships' revenues are the prices received for
      the  sale of oil and gas and  the  volumes  of oil and gas  produced.  The
      Partnerships'  production  is mainly  natural  gas,  so such  pricing  and
      volumes are the most significant factors.

      Due to the volatility of oil and gas prices,  forecasting future prices is
      subject to great  uncertainty  and  inaccuracy.  Substantially  all of the
      Partnerships' gas reserves are being sold in the "spot market".  Prices on
      the  spot  market  are  subject  to wide  seasonal  and  regional  pricing
      fluctuations due to the highly competitive nature of the spot market. Such
      spot market sales are  generally  short-term  in nature and are  dependent
      upon the obtaining of transportation services provided by pipelines. It is
      likewise difficult to predict production volumes. However, oil and gas are
      depleting  assets,  so it can be  expected  that  production  levels  will
      decline   over  time.   Recent  gas  prices  have  been  higher  than  the
      Partnerships'  historical  average.  This is  attributable  to the  higher
      prices for crude oil,  a  substitute  fuel in some  markets,  and  reduced
      production due to low prices in 1998.

                                           --------       --------
      Net Profits                          $290,633       $157,465
      Barrels produced                        5,732          7,426
      Mcf produced                           92,487        118,847
      Average price/Bbl                    $  27.33       $  10.22
      Average price/Mcf                    $   2.25       $   1.53

      As shown in the table above,  total Net Profits increased $133,168 (84.6%)
      for the three  months ended March 31, 2000 as compared to the three months
      ended March 31, 1999. Of this increase, approximately $98,000 and $66,000,
      respectively,  were related to increases in the average  prices of oil and
      gas sold and approximately $26,000 was related to a decrease in production
      expenses. These increases were partially offset by decreases of



                                      -25-




      approximately $17,000 and $40,000,  respectively,  related to decreases in
      volumes of oil and gas sold.  Volumes of oil and gas sold decreased  1,694
      barrels and 26,360 Mcf, respectively, for the three months ended March 31,
      2000 as compared to the three months ended March 31, 1999. The decrease in
      volumes of oil sold was  primarily  due to positive  prior  period  payout
      related volume  adjustments made by the operators on two significant wells
      during  the three  months  ended  March 31,  1999 and normal  declines  in
      production.  The  decrease in volumes of gas sold was  primarily  due to a
      positive  prior  period  payout  related  volume  adjustment  made  by the
      operator  during the three months ended March 31, 1999 and normal declines
      in  production.  The decrease in production  expenses was primarily due to
      (i) a decrease in lease operating  expenses  associated with the decreases
      in volumes of oil and gas sold, (ii) workover expenses incurred during the
      three  months  ended  March 31, 1999 on one  significant  well in order to
      improve the recovery of reserves,  and (iii) a positive prior period lease
      operating expense  adjustment on another  significant well made during the
      three months ended March 31, 1999. Average oil and gas prices increased to
      $27.33 per barrel and $2.25 per Mcf,  respectively,  for the three  months
      ended   March  31,  2000  from  $10.22  per  barrel  and  $1.53  per  Mcf,
      respectively, for the three months ended March 31, 1999.

      Depletion of Net Profits Interests decreased $25,548 (38.1%) for the three
      months  ended March 31, 2000 as compared to the three  months  ended March
      31, 1999.  This  decrease was primarily due to the decreases in volumes of
      oil and gas sold and upward  revisions in the  estimates of remaining  oil
      and gas  reserves at December 31,  1999.  As a percentage  of Net Profits,
      this expense  decreased to 14.3% for the three months ended March 31, 2000
      from 42.5% for the three  months  ended March 31,  1999.  This  percentage
      decrease was primarily  due to the increases in the average  prices of oil
      and  gas  sold  and  the  dollar  decrease  in  depletion  of Net  Profits
      Interests.

      General and  administrative  expenses  increased $472 (1.2%) for the three
      months  ended March 31, 2000 as compared to the three  months  ended March
      31, 1999.  As a percentage  of Net Profits,  these  expenses  decreased to
      13.3% for the three  months  ended March 31, 2000 from 24.2% for the three
      months ended March 31, 1999. This percentage decrease was primarily due to
      the increase in Net Profits.

      Cumulative cash  distributions  to the Limited  Partners through March 31,
      2000  were  $12,129,558  or  112.23%  of  the  Limited  Partners'  capital
      contributions.

      Average price/Mcf                   $   1.89       $   1.53

      As shown in the table above,  total Net Profits  increased $68,923 (57.3%)
      for the three  months ended March 31, 2000 as compared to the three months
      ended March 31, 1999. Of this increase, approximately $69,000 and $26,000,
      respectively,  were related to increases in the average  prices of oil and
      gas sold and approximately $21,000 was related to a decrease in production
      expenses.   These   increases  were  partially   offset  by  decreases  of
      approximately $14,000 and $33,000,  respectively,  related to decreases in
      volumes of oil and gas sold.  Volumes of oil and gas sold decreased  1,323
      barrels and 21,722 Mcf, respectively, for the three months ended March 31,
      2000 as compared to the three months ended March 31, 1999. The decrease in
      volumes of oil sold was  primarily  due to positive  prior  period  volume
      adjustments  made by the  operators  on two  significant  wells during the
      three months ended March 31, 1999 and normal  declines in production.  The
      decrease  in volumes  of gas sold was  primarily  due to a positive  prior
      period payout related volume  adjustment  made by the operator  during the
      three months ended March 31, 1999 and normal  declines in production.  The
      decrease in  production  expenses was  primarily  due to (i) a decrease in
      lease operating  expenses  associated with the decreases in volumes of oil
      and gas sold,  (ii)  workover  expenses  incurred  during the three months
      ended  March 31,  1999 on one  significant  well in order to  improve  the
      recovery of reserves,  and (iii) a positive  prior period lease  operating
      expense  adjustment  on  another  significant  well made  during the three
      months  ended  March 31,  1999.  Average oil and gas prices  increased  to
      $27.33 per barrel and $1.89 per Mcf,  respectively,  for the three  months
      ended   March  31,  2000  from  $10.29  per  barrel  and  $1.53  per  Mcf,
      respectively, for the three months ended March 31, 1999.

      Depletion of Net Profits Interests decreased $20,605 (38.0%) for the three
      months  ended March 31, 2000 as compared to the three  months  ended March
      31, 1999.  This decrease was primarily due to (i) the decreases in volumes
      of oil  and gas  sold  and  (ii)  upward  revisions  in the  estimates  of
      remaining  oil and gas reserves at December 31, 1999.  As a percentage  of
      Net Profits,  this  expense  decreased to 17.7% for the three months ended
      March 31, 2000 from 45.0% for the three months ended March 31, 1999.  This
      percentage  decrease  was  primarily  due to the  increases in the average
      prices of oil and gas sold and the dollar  decrease  in  depletion  of Net
      Profits Interests.

      General and  administrative  expenses  increased $324 (1.0%) for the three
      months  ended March 31, 2000 as compared to the three  months  ended March

      As shown in the table above,  total Net Profits increased $116,595 (52.2%)
      for the three  months ended March 31, 2000 as compared to the three months
      ended  March  31,  1999.  Of this  increase,  approximately  $127,000  and
      $38,000, respectively,  were related to increases in the average prices of
      oil and gas sold and  approximately  $39,000  was related to a decrease in
      production expenses. These increases were partially offset by decreases of
      approximately $25,000 and $62,000,  respectively,  related to decreases in
      volumes of oil and gas sold.  Volumes of oil and gas sold decreased  2,436
      barrels and 40,389 Mcf, respectively, for the three months ended March 31,
      2000 as compared to the three months ended March 31, 1999. The



                                      -28-




      decrease in volumes of oil sold was primarily due to positive prior period
      volume  adjustments made by the operators on two significant  wells during
      the three months ended March 31, 1999 and normal  declines in  production.
      The decrease in volumes of gas sold was primarily due to a positive  prior
      period payout related volume  adjustment  made by the operator  during the
      three months ended March 31, 1999 and normal  declines in production.  The
      decrease in  production  expenses was  primarily  due to (i) a decrease in
      lease operating  expenses  associated with the decreases in volumes of oil
      and gas sold,  (ii)  workover  expenses  incurred  during the three months
      ended  March 31,  1999 on one  significant  well in order to  improve  the
      recovery of reserves,  and (iii) a positive  prior period lease  operating
      expense  adjustment  on  another  significant  well made  during the three
      months  ended  March 31,  1999.  Average oil and gas prices  increased  to
      $27.33 per barrel and $1.81 per Mcf,  respectively,  for the three  months
      ended   March  31,  2000  from  $10.29  per  barrel  and  $1.53  per  Mcf,
      respectively, for the three months ended March 31, 1999.

      Depletion of Net Profits Interests decreased $38,566 (38.3%) for the three
      months  ended March 31, 2000 as compared to the three  months  ended March
      31, 1999.  This  decrease was primarily due to the decreases in volumes of
      oil and gas sold and upward  revisions in the  estimates of remaining  oil
      and gas  reserves at December 31,  1999.  As a percentage  of Net Profits,
      this expense  decreased to 18.3% for the three months ended March 31, 2000
      from 45.2% for the three  months  ended March 31,  1999.  This  percentage
      decrease was primarily  due to the increases in the average  prices of oil
      and  gas  sold  and  the  dollar  decrease  in  depletion  of Net  Profits
      Interests.

      The P-3  Partnership  should  achieve payout during the three months ended
      June  30,  2000.  After  payout,  operations  and  revenues  for  the  P-3
      Partnership will be allocated using after payout percentages. After payout
      percentages  allocate  operating  income and  expenses  10% to the General
      Partner and 90% to the Limited Partners.  Before payout,  operating income
      and  expenses  are  allocated  5% to the  General  Partner  and 95% to the
      Limited Partners. See the Partnerships' Annual Report on Form 10-K for the
      year ended  December  31,  1999 for a further  discussion  of pre and post
      payout allocations of income and expense.

      General and  administrative  expenses  increased $734 (1.2%) for the three
      months  ended March 31, 2000 as compared to the three  months  ended March
      31, 1999.  As a percentage  of Net Profits,  these  expenses  decreased to
      17.8% for the three  months  ended March 31, 2000 from 26.8% for the three
      months ended March 31, 1999. This percentage decrease was primarily due to
      the increase in Net Profits.

      As shown in the table above,  total Net Profits  increased $85,519 (66.1%)
      for the three  months ended March 31, 2000 as compared to the three months
      ended March 31, 1999. Of this increase, approximately $97,000 and $30,000,
      respectively,  were related to increases in the average  prices of oil and
      gas sold and  approximately  $17,000 was related to an increase in volumes
      of oil  sold.  These  increases  were  partially  offset by  decreases  of
      approximately (i) $36,000 related to a decrease in volumes of gas sold and
      (ii) $22,000 related to an increase in production expenses. Volumes of oil
      sold increased  1,517 barrels while volumes of gas sold  decreased  21,917
      Mcf for the three  months  ended  March 31,  2000 as compared to the three
      months  ended  March 31,  1999.  The  increase  in volumes of oil sold was
      primarily due to increased  production on two wells  following  successful
      workovers  completed during late 1999. The decrease in volumes of gas sold
      was  primarily  due to normal  declines  in  production.  The  increase in
      production  expenses was primarily due to an increase in production  taxes
      associated  with the increase in Net  Profits.  Average oil and gas prices
      increased  to $26.70 per barrel and $2.05 per Mcf,  respectively,  for the
      three  months  ended  March 31,  2000 from $10.90 per barrel and $1.66 per
      Mcf, respectively, for the three months ended March 31, 1999.

      Depletion of Net Profits Interests decreased $14,808 (24.7%) for the three
      months  ended March 31, 2000 as compared to the three  months  ended March
      31, 1999.  This  decrease was  primarily due to the decrease in volumes of
      gas sold and upward  revisions in the  estimates of remaining  oil and gas
      reserves at December  31,  1999.  As a  percentage  of Net  Profits,  this
      expense  decreased to 21.0% for the three months ended March 31, 2000 from
      46.3% for the three months ended March 31, 1999. This percentage  decrease
      was



                                      -30-




      primarily due the increases in the average prices of oil and gas sold.

      for the three  months ended March 31, 2000 as compared to the three months
      ended  March  31,  1999.  Of  this  increase,  approximately  $28,000  and
      $102,000, respectively, were related to increases in the average prices of
      oil and gas sold.  These increases were partially  offset by a decrease of
      approximately  $29,000  related to an  increase  in  production  expenses.
      Volumes  of oil sold  increased  125  barrels,  while  volumes of gas sold
      decreased  5,802 Mcf for the three months ended March 31, 2000 as compared
      to the three  months  ended March 31,  1999.  The  increase in  production
      expenses  was  primarily  due to  (i)  an  increase  in  production  taxes
      associated with the increase in Net Profits and (ii) the timing of payment
      of ad valorem taxes on three significant wells. Average oil and gas prices
      increased  to $28.30 per barrel and $2.34 per Mcf,  respectively,  for the
      three  months  ended  March 31,  2000 from $11.50 per barrel and $1.48 per
      Mcf, respectively, for the three months ended March 31, 1999.

      Depletion of Net Profits Interests decreased $14,101 (26.4%) for the three
      months  ended March 31, 2000 as compared to the three  months  ended March
      31, 1999.  This  decrease was  primarily due to the decrease in volumes of
      gas sold and upward  revisions in the  estimates of remaining  oil and gas
      reserves at December  31,  1999.  As a  percentage  of Net  Profits,  this
      expense  decreased to 16.5% for the three months ended March 31, 2000 from
      37.0% for the three months ended March 31, 1999. This percentage  decrease
      was primarily  due to the  increases in the average  prices of oil and gas
      sold.

      General and  administrative  expenses  increased $489 (1.2%) for the three
      months  ended March 31, 2000 as compared to the three  months  ended March

      Barrels produced                        4,203          2,714
      Mcf produced                          215,861        235,103
      Average price/Bbl                    $  26.81       $  10.74
      Average price/Mcf                    $   2.44       $   1.43

      As shown in the table above, total Net Profits increased $247,516 (119.3%)
      for the three  months ended March 31, 2000 as compared to the three months
      ended  March  31,  1999.  Of  this  increase,  approximately  $68,000  and
      $218,000, respectively, were related to increases in the average prices of
      oil and gas sold.  These  increases were partially  offset by decreases of
      approximately (i) $28,000 related to a decrease in volumes of gas sold and
      (ii) $27,000 related to an increase in production expenses. Volumes of oil
      sold increased 1,489 barrels,  while volumes of gas sold decreased  19,242
      Mcf for the three  months  ended  March 31,  2000 as compared to the three
      months  ended  March 31,  1999.  The  increase  in volumes of oil sold was
      primarily  due to the sale during the three months ended March 31, 2000 of
      oil on



                                      -32-




      several wells which had  previously  been curtailed due to low oil prices.
      The increase in  production  expenses was primarily due to (i) an increase
      in production  taxes  associated with the increase in Net Profits and (ii)
      the  timing of  payment  of ad  valorem  taxes on two  significant  wells.
      Average  oil and gas prices  increased  to $26.81 per barrel and $2.44 per
      Mcf,  respectively,  for the three months ended March 31, 2000 from $10.74
      per barrel and $1.43 per Mcf,  respectively,  for the three  months  ended
      March 31, 1999.

      Depletion of Net Profits Interests decreased $23,111 (22.4%) for the three
      months  ended March 31, 2000 as compared to the three  months  ended March
      31, 1999.  This  decrease was  primarily due to the decrease in volumes of
      gas sold and upward  revisions in the  estimates of remaining  oil and gas
      reserves at December  31,  1999.  As a  percentage  of Net  Profits,  this
      expense  decreased to 17.6% for the three months ended March 31, 2000 from
      49.7% for the three months ended March 31, 1999. This percentage  decrease
      was primarily  due to the  increases in the average  prices of oil and gas
      sold.

      General and  administrative  expenses  increased $609 (1.2%) for the three
      months  ended March 31, 2000 as compared to the three  months  ended March
      31, 1999.  As a percentage  of Net Profits,  these  expenses  decreased to
      11.2% for the three  months  ended March 31, 2000 from 24.3% for the three
      months ended March 31, 1999. This percentage decrease was primarily due to
      the increase in Net Profits.

      Cumulative cash  distributions  to the Limited  Partners through March 31,
      2000  were  $11,127,248  or  77.79%  of  the  Limited   Partners'  capital
      contributions.


YEAR 2000 COMPUTER ISSUES
- -------------------------

      The year  2000  issue  refers  to the  inability  of  computer  and  other
      information   technology   systems  to  properly  process  date  and  time
      information,  stemming from the earlier programming  practice of using two
      digits  rather than four to represent the year in a date. To the knowledge
      of the General Partner, the Partnerships have not experienced any material
      effects from the year 2000 issue.  Costs incurred by the  Partnerships  in
      order  to  ensure  year  2000  compatibility  were  not  material  to  the
      Partnerships.

           RISK.
