              CONDENSED NOTES TO THE COMBINED FINANCIAL STATEMENTS
                                  JUNE 30, 1999
                                   (Unaudited)


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

      The combined  balance sheets as of June 30, 1999,  combined  statements of
      operations  for the three and six months ended June 30, 1999 and 1998, and
      combined  statements  of cash flows for the six months ended June 30, 1999
      and 1998 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 June 30, 1999, the combined results of operations for the three and six
      months ended June 30, 1999 and 1998,  and the combined  cash flows for the
      six months ended June 30, 1999 and 1998.

      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, 1998. The
      results  of  operations  for  the  period  ended  June  30,  1999  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.






                                      -26-





      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  June 30,  1999 the  following  payments  were  made to the  General
      Partner or its affiliates 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




                                      -29-





      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 June 30, 1999 and the net
      revenue generated from future operations will provide  sufficient  working
      capital to meet current and future obligations.

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
      variable  affecting the Partnerships'  revenues is the prices received for
      the  sale of oil and gas.  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.  In addition,  crude oil prices were  recently at or near their
      lowest  level in the past decade due  primarily  to the global  surplus of
      crude oil.  However,  as of the date of this  Quarterly  Report oil prices
      have rebounded  primarily due to a decrease in the global oil surplus as a
      result of production  curtailments by several major oil producing nations.
      Management is unable to predict whether future oil and gas prices will (i)
      stabilize, (ii) increase, or (iii) decrease.

      Mcf produced                                  84,519           72,268
      Average price/Bbl                           $  14.98         $  15.89
      Average price/Mcf                           $   1.78         $   1.84

      As shown in the table above, total Net Profits decreased $5,250 (2.6%) for
      the three months ended June 30, 1999 as compared to the three months ended
      June  30,  1998.  Of  this  decrease,  approximately  $6,000  and  $5,000,
      respectively,  were related to decreases in the average  prices of oil and
      gas sold and approximately $26,000 was related to a decrease in volumes of
      oil sold.  These  decreases  were  partially  offset by  increases  of (i)
      approximately  $23,000  related to an  increase in volumes of gas sold and
      (ii)  approximately  $9,000  related to a decrease in production  expenses
      incurred




                                      -31-





      by the owners of the  Working  Interests.  Volumes  of oil sold  decreased
      1,627 barrels while volumes of gas sold increased 12,251 Mcf for the three
      months  ended June 30, 1999 as compared to the three months ended June 30,
      1998.  The decrease in volumes of oil sold was primarily due to a positive
      prior period  volume  adjustment  made by the  purchaser on several  wells
      during the three months  ended June 30,  1998.  The increase in volumes of
      gas sold was primarily due to (i) increased  production on one significant
      well due to repairs made during 1998 and (ii) the successful  recompletion
      of  another  significant  well  during the  fourth  quarter  of 1998.  The
      decrease in production  expenses was primarily due to (i) a negative prior
      period  adjustment of production  taxes by the operator of one significant
      well  during  the  three  months  ended  June 30,  1999 and (ii)  workover
      expenses incurred during the three months ended June 30, 1998 on two other
      significant  wells in order to improve the recovery of  reserves.  Average
      oil and gas  prices  decreased  to $14.98  per  barrel  and $1.78 per Mcf,
      respectively,  for the three  months  ended June 30,  1999 from $15.89 per
      barrel and $1.84 per Mcf,  respectively,  for the three  months ended June
      30, 1998.

      The P-1 Partnership  sold certain Net Profits  Interests  during the three
      months ended June 30, 1999 and recognized a $34 gain on such sales.  Sales
      of Net  Profits  Interests  during the three  months  ended June 30,  1998
      resulted in the P-1 Partnership recognizing similar gains of $392,604.

      Depletion of Net Profits  Interests  decreased $3,792 (7.0%) for the three
      months  ended June 30, 1999 as compared to the three months ended June 30,
      1998. As a percentage of Net Profits,  this expense decreased to 25.4% for
      the three months ended June 30, 1999 from 26.6% for the three months ended
      June 30, 1998.

      General and  administrative  expenses  increased $431 (1.4%) for the three
      months  ended June 30, 1999 as compared to the three months ended June 30,
      1998. As a percentage of Net Profits,  these  expenses  increased to 15.3%
      for the three  months  ended June 30, 1999 from 14.7% for the three months
      ended June 30, 1998.

      for the six months ended June 30, 1999 as compared to the six months ended
      June 30,  1998.  Of this  decrease,  approximately  $37,000  and  $66,000,
      respectively,  were related to decreases in the average  prices of oil and
      gas sold,  approximately  $18,000  was related to a decrease in volumes of
      oil  sold,  and  approximately  $25,000  was  related  to an  increase  in
      production expenses incurred by the owners of the Working Interests. These
      decreases were partially  offset by an increase of  approximately  $79,000
      related  to an  increase  in  volumes  of gas  sold.  Volumes  of oil sold
      decreased 1,161 barrels while volumes of gas sold increased 40,112 Mcf for
      the six months  ended June 30, 1999 as  compared  to the six months  ended
      June 30, 1998.  The increase in volumes of gas sold was  primarily  due to
      (i) a positive prior period volume  adjustment made by the operator during
      the six months  ended June 30,  1999 due to the payout of one  significant
      well,  (ii) the  successful  recompletion  of one well  during  the fourth
      quarter of 1998, and (iii) increased  production on one  significant  well
      due to repairs made during 1998.  The increase in production  expenses was
      primarily  due to (i) ad valorem  taxes paid  during the six months  ended
      June 30, 1999, (ii) workover  expenses  incurred on one  significant  well
      during the six months ended June 30, 1999 in order to improve the recovery
      of reserves, and (iii) lease operating expenses paid during the six months
      ended June 30,  1999  related to prior  periods on the well which  reached
      payout.  Average  oil and gas  prices  decreased  to $12.42 per barrel and
      $1.64 per Mcf,  respectively,  for the six months ended June 30, 1999 from
      $15.08  per  barrel  and $1.96 per Mcf,  respectively,  for the six months
      ended June 30, 1998.

      The P-1  Partnership  sold  certain Net Profits  Interests  during the six
      months ended June 30, 1999 and recognized a $698 gain on such sales. Sales
      of Net  Profits  Interests  during  the six  months  ended  June 30,  1998
      resulted in the P-1 Partnership recognizing similar gains of $475,798.

      Average price/Mcf                          $   1.95          $   1.89

      As shown in the table above, total Net Profits increased $8,718 (5.7%) for
      the three months ended June 30, 1999 as compared to the three months ended
      June 30, 1998. Of this increase,  approximately  $18,000 was related to an
      increase  in volumes of gas sold,  approximately  $4,000 was related to an
      increase in the average price of gas sold,  and  approximately  $7,000 was
      related to a decrease in production expenses incurred by the owners of the
      Working  Interests.  These increases were partially offset by decreases of
      approximately (i) $16,000 related to a decrease in volumes of oil sold and
      (ii)  $4,000  related  to a  decrease  in the  average  price of oil sold.
      Volumes of oil sold  decreased  1,036  barrels  while  volumes of gas sold
      increased  9,812 Mcf for the three  months ended June 30, 1999 as compared
      to the three months  ended June 30,  1998.  The decrease in volumes of oil
      sold was primarily due to a positive prior period volume  adjustment  made
      by the  purchaser on several  wells during the three months ended June 30,
      1998. The increase




                                      -34-





      in  volumes  of  gas  sold  was  primarily  due  to  (i)  the   successful
      recompletion of another significant well during the fourth quarter of 1998
      and (ii) increased  production on another  significant well due to repairs
      made during 1998. The decrease in production expenses was primarily due to
      (i) a negative  prior period  adjustment of  production  taxes made by the
      operator on one  significant  well during the three  months ended June 30,
      1999 and (ii)  workover  expenses  incurred  during the three months ended
      June 30, 1998 on two significant wells in order to improve the recovery of
      reserves.  Average gas prices decreased to $14.93 per barrel for the three
      months  ended June 30,  1999 from  $15.84 per barrel for the three  months
      ended June 30, 1998. Average gas prices increased to $1.95 per Mcf for the
      three  months  ended June 30, 1999 from $1.89 per Mcf for the three months
      ended June 30, 1998.

      and  approximately  $21,000  was  related  to an  increase  in  production
      expenses incurred by the owners of the Working Interests.  These decreases
      were partially offset by an increase of  approximately  $62,000 related to
      an  increase  in volumes of gas sold.  Volumes of oil sold  decreased  635
      barrels while volumes of gas sold increased  31,251 Mcf for the six months
      ended June 30, 1999 as compared to the six months ended June 30, 1998. The

      ended June 30, 1998.

      The P-3  Partnership  sold  certain Net Profits  Interests  during the six
      months  ended June 30,  1999 and  recognized  a $1,252 gain on such sales.
      Sales of Net Profits  Interests  during the six months ended June 30, 1998
      resulted in the P-3 Partnership recognizing similar gains of $605,649.

      Depletion of Net Profits  Interests  increased  $16,100 (9.9%) for the six
      months  ended June 30, 1999 as  compared to the six months  ended June 30,
      1998. As a percentage of Net Profits,  this expense increased to 33.8% for
      the six  months  ended June 30,  1999 from 27.2% for the six months  ended
      June 30, 1998. This percentage increase was primarily due to the decreases
      in the average prices of oil and gas sold.

      General and  administrative  expenses  increased $1,719 (1.6%) for the six
      months  ended June 30, 1999 as  compared to the six months  ended June 30,

      for the six months ended June 30, 1999 from 17.7% for the six months ended
      June 30, 1998. This percentage  increase was primarily due to the decrease
      in Net Profits.

      As shown in the table above,  total Net Profits  increased $22,993 (12.9%)
      for the three  months  ended June 30, 1999 as compared to the three months
      ended June 30, 1998. Of this increase,  approximately  $24,000 was related
      to a decrease in production expenses incurred by the owners of the Working
      Interests  and  approximately  $12,000  was  related to an increase in the
      average  price of oil  sold.  These  increases  were  partially  offset by
      decreases of approximately (i) $10,000 related to a decrease in volumes of
      gas sold and (ii) $4,000 related to a decrease in the average price of gas
      sold.  Volumes of oil sold  increased 1 barrel  while  volumes of gas sold
      decreased  4,237 Mcf for the three  months ended June 30, 1999 as compared
      to the three  months  ended June 30,  1998.  The  decrease  in  production
      expenses was  primarily due to (i) workover  expenses  incurred on several
      wells  during the three months ended June 30, 1998 in order to improve the
      recovery of reserves,  (ii) ad valorem  taxes paid during the three months
      ended  June 30,  1998,  and (iii) a general  decrease  in lease  operating
      expenses.  Average oil prices increased to $15.05 per barrel for the three
      months  ended June 30,  1999 from  $12.29 per barrel for the three  months
      ended June 30, 1998. Average gas prices decreased to $2.21 per Mcf for the
      three  months  ended June 30, 1999 from $2.25 per Mcf for the three months
      ended June 30, 1998.

      Depletion of Net Profits Interests  decreased $7,782 (12.5%) for the three
      months  ended June 30, 1999 as compared to the three months ended June 30,
      1998.  This  decrease was  primarily due to (i) the decrease in volumes of
      gas sold and (ii) upward  revisions in the  estimates of remaining oil and
      gas reserves at December 31, 1998.  As a percentage  of Net Profits,  this
      expense  decreased  to 27.0% for the three months ended June 30, 1999 from
      34.9% for the three months ended June 30, 1998. This  percentage  decrease
      was primarily due to the increase in the average price of oil sold.

      for the six months ended June 30, 1999 as compared to the six months ended
      June 30, 1998. Of this  decrease,  approximately  $58,000 was related to a
      decrease in the average  price of gas sold and  approximately  $21,000 was
      related to a decrease in volumes of gas sold.  Volumes of oil and gas sold
      decreased  199  barrels  and 9,494 Mcf,  respectively,  for the six months
      ended June 30,  1999 as compared  to the six months  ended June 30,  1998.

      months  ended June 30, 1999 as  compared to the six months  ended June 30,
      1998.  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, 1998. As a percentage of Net Profits,
      this  expense  increased  to 34.6% for the six months  ended June 30, 1999
      from  31.4%  for the six  months  ended  June 30,  1998.  This  percentage
      increase was primarily  due to the decreases in the average  prices of oil
      and gas sold.

      As shown in the table above,  total Net Profits  increased  $17,292 (9.5%)
      for the three  months  ended June 30, 1999 as compared to the three months
      ended June 30, 1998. Of this increase,  approximately  $10,000 was related
      to an increase in volumes of oil sold,  approximately  $7,000 and $24,000,
      respectively,  were related to increases in the average  prices of oil and
      gas sold, and approximately $6,000 was related to a decrease in production
      expenses incurred by the owners of the Working Interests.  These increases
      were partially offset by a decrease of approximately  $30,000 related to a
      decrease in volumes of gas sold. Volumes of oil sold increased 791 barrels
      while volumes of gas sold decreased  17,572 Mcf for the three months ended
      June 30, 1999 as compared to the three  months  ended June 30,  1998.  The
      increase  in  volumes  of oil sold was  primarily  due to the  receipt  of
      revenues on a well which paid out in late 1998. The decrease in volumes of
      gas sold was  primarily due to positive  prior period  volume  adjustments
      made by the  purchasers on two  significant  wells during the three months
      ended June 30, 1998. The decrease in production expenses was primarily due
      to repair and  maintenance  expenses  incurred on several wells during the
      six months  ended June 30, 1998.  Average oil and gas prices  increased to
      $15.29 per barrel and $1.89 per Mcf,  respectively,  for the three  months
      ended  June  30,   1999  from   $12.26  per  barrel  and  $1.68  per  Mcf,
      respectively, for the three months ended June 30, 1998.

      The P-5 Partnership  sold certain Net Profits  Interests  during the three

      Depletion of Net Profits Interests  decreased $9,853 (16.0%) for the three
      months  ended June 30, 1999 as compared to the three months ended June 30,
      1998.  This  decrease was  primarily due to (i) the decrease in volumes of
      gas sold and (ii) one significant well being fully depleted in 1998 due to
      the lack of  remaining  reserves.  As a percentage  of Net  Profits,  this
      expense  decreased  to 25.9% for the three months ended June 30, 1999 from
      33.7% for the three months ended June 30, 1998. This  percentage  decrease
      was primarily  due to the  increases in the average  prices of oil and gas
      sold.

      for the six months ended June 30, 1999 as compared to the six months ended
      June 30, 1998. Of this  decrease,  approximately  $77,000 was related to a
      decrease in the average  price of gas sold and  approximately  $34,000 was
      related  to a  decrease  in  volumes  of gas sold.  These  decreases  were
      partially  offset by an increase  of  approximately  $20,000  related to a
      decrease  in  production  expenses  incurred  by the owners of the Working
      Interests.  Volumes of oil sold increased 561 barrels while volumes of gas
      sold  decreased  16,874  Mcf for the six  months  ended  June 30,  1999 as
      compared to the six months ended June 30, 1998. The increase in volumes of
      oil sold was primarily due to the receipt of revenues on a well which paid
      out in late 1998. The decrease in production expenses was primarily due to
      (i) a decrease in  production  taxes  associated  with the decrease in Net
      Profits,  (ii) a decrease in ad valorem taxes paid on one significant well
      during the six months ended June 30,

      1999 as compared to the six months ended June 30,  1998,  and (iii) repair
      and maintenance  expenses  incurred on one significant well during the six
      months ended June 30, 1998. Average oil and gas prices decreased to $13.79
      per barrel and $1.68 per Mcf, respectively,  for the six months ended June
      30, 1999 from $14.99 per barrel and $2.00 per Mcf,  respectively,  for the
      six months ended June 30, 1998.

      The P-5  Partnership  sold  certain Net Profits  Interests  during the six
      months ended June 30, 1998 and  recognized a $340,014  gain of such sales.
      No such gains were recognized on sales of Net Profits Interests during the
      six months ended June 30, 1999.

      Depletion of Net Profits  Interests  decreased $14,633 (12.2%) for the six
      months  ended June 30, 1999 as  compared to the six months  ended June 30,
      1998.  This  decrease was  primarily due to (i) the decrease in volumes of
      gas sold and (ii) one significant well being fully depleted in 1998 due to
      the lack of  remaining  reserves.  As a percentage  of Net  Profits,  this
      expense  increased  to 30.5% for the six months  ended June 30,  1999 from
      27.8% for the six months ended June 30, 1998. This percentage increase was
      primarily due to the decreases in the average prices of oil and gas sold.

      General and  administrative  expenses  increased $1,244 (1.7%) for the six
      months  ended June 30, 1999 as  compared to the six months  ended June 30,

      for the three months ended June 30, 1999 as




                                      -44-





      compared  to the three  months  ended  June 30,  1998.  Of this  increase,
      approximately $11,000 and $25,000, respectively, were related to increases
      in the  average  prices of oil and gas  sold,  approximately  $39,000  was
      related to an increase in volumes of oil sold, and  approximately  $27,000
      was related to a decrease in production expenses incurred by owners of the
      Working Interests.  These increases were partially offset by a decrease of
      approximately  $33,000  related  to a  decrease  in  volumes  of gas sold.
      Volumes of oil sold  increased  3,288  barrels  while  volumes of gas sold
      decreased  18,689 Mcf for the three months ended June 30, 1999 as compared
      to the three months  ended June 30,  1998.  The increase in volumes of oil
      sold was primarily due to (i) the receipt of revenues on a well which paid
      out in  late  1998,  (ii)  the  sale of oil on  several  wells  which  had
      previously been curtailed due to low oil prices,  and (iii) the successful
      recompletion of one well in 1998. The decrease in production  expenses was
      primarily  due  to  (i) a  decrease  in  ad  valorem  taxes  paid  on  two
      significant  wells  during the three months ended June 30, 1999 and (ii) a
      decrease in repair and  maintenance  expenses  incurred on two significant
      wells during the three months ended June 30, 1999 as compared to the three
      months ended June 30, 1998. Average oil and gas prices increased to $13.61
      per barrel and $1.91 per Mcf,  respectively,  for the three  months  ended
      June 30, 1999 from $11.89 per barrel and $1.78 per Mcf, respectively,  for
      the three months ended June 30, 1998.

      The P-6 Partnership  sold certain Net Profits  Interests  during the three
      months ended June 30, 1998 and recognized a $68,179 gain on such sales. No
      such gains were  recognized on sales of Net Profits  Interests  during the
      three months ended June 30, 1999.

      Depletion  of Net Profits  Interests  decreased  $393 (0.4%) for the three
      months  ended June 30, 1999 as compared to the three months ended June 30,
      1998. As a percentage of Net Profits,  this expense decreased to 29.0% for
      the three months ended June 30, 1999 from 36.3% for the three months ended
      June 30, 1998. This percentage decrease was primarily due to the increases
      in the average prices of oil and gas sold.

      General and  administrative  expenses  increased $419 (1.1%) for the three
      months  ended June 30, 1999 as compared to the three months ended June 30,
      1998. As a percentage of Net Profits,  these  expenses  decreased to 11.6%
      for the three  months  ended June 30, 1999 from 14.3% for the three months
      ended June 30, 1998.  This  percentage  decrease was  primarily due to the
      increase in Net Profits.

      As shown in the table above,  total Net Profits  decreased  $61,394 (9.9%)
      for the six months ended June 30, 1999 as compared to the six months ended
      June 30,  1998.  Of this  decrease,  approximately  $12,000 and  $119,000,
      respectively,  were related to decreases in the average  prices of oil and
      gas  sold,   which  decreases  were  partially   offset  by  increases  of
      approximately  $33,000 and $7,000,  respectively,  related to increases in
      volumes  of oil and gas  sold and an  increase  of  approximately  $29,000
      related to a decrease in production expenses incurred by the owners of the
      Working Interests. Volumes of oil and gas sold increased 2,341 barrels and
      3,838  Mcf,  respectively,  for the six  months  ended  June  30,  1999 as
      compared to the six months ended June 30, 1998. The increase in volumes of
      oil sold was  primarily due to (i) the receipt of revenues on a well which
      paid out in late  1998,  (ii) the sale of oil on several  wells  which had
      previously been curtailed due to low oil prices,  and (iii) the successful
      recompletion of one well in 1998. The decrease in production  expenses was
      primarily due to (i) a decrease in production  taxes  associated  with the
      decrease in Net  Profits  and (ii) a decrease in ad valorem  taxes paid on
      three significant wells during the six months ended June 30, 1999. Average
      oil and gas  prices  decreased  to $12.77  per  barrel  and $1.65 per Mcf,
      respectively,  for the six  months  ended  June 30,  1999 from  $14.10 per
      barrel and $1.92 per Mcf, respectively,  for the six months ended June 30,
      1998.

      The P-6  Partnership  sold  certain Net Profits  Interests  during the six
      months ended June 30, 1998 and  recognized a $134,525  gain on such sales.
      No such gains were recognized on sales of Net Profits Interests during the
      six months ended June 30, 1999.

      Depletion of Net Profits  Interests  increased  $5,733  (2.9%) for the six
      months  ended June 30, 1999 as  compared to the six months  ended June 30,
      1998. As a percentage of Net Profits,  this expense increased to 36.7% for
      the six  months  ended June 30,  1999 from 32.1% for the six months  ended
      June 30, 1998. This percentage increase was primarily due to the decreases
      in the average prices of oil and gas sold.

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

      IN GENERAL

      The Year 2000 Issue ("Y2K")  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.  For  example,
      computer programs and imbedded chips that are date sensitive may recognize
      a date  using  (00) as the  year  1900  rather  than the  year  2000.  The
      consequence of Y2K is that computer and imbedded processing systems may be
      at risk of malfunctioning, particularly during the transition from 1999 to
      2000.

      The effects of Y2K are exacerbated by the  interdependence of computer and
      telecommunication  systems throughout the world. This interdependence also
      exists  among  the  Partnerships,   Samson  Investment   Company  and  its
      affiliates  ("Samson"),   and  their  vendors,   customers,  and  business
      partners, as well as with regulators.  The potential risks associated with
      Y2K for an oil and gas  production  company fall into three general areas:
      (i)  financial,   leasehold  and  administrative  computer  systems,  (ii)
      imbedded  systems in field process  control  units,  and (iii) third party
      exposures. As discussed below, General Partner does not believe that these
      risks will be material to the Partnerships' operations.

      The  Partnerships'  business  is  producing  oil and gas.  The  day-to-day
      production of the  Partnerships' oil and gas is not dependent on computers
      or equipment with imbedded chips. As further  discussed below,  management
      anticipates that the Partnerships'  daily business  activities will not be
      materially affected by Y2K.

      The  Partnerships  rely on Samson to provide all of their  operational and
      administrative  services on either a direct or indirect  basis.  Samson is
      addressing each of the three




                                      -47-





      Y2K areas discussed above through a readiness process that seeks to:

      1.    increase the awareness of the issue among key employees;
      2.    identify areas of potential risk;
      3.    assess the relative  impact of these risks and Samson's  ability to
            manage them; and
      4.    remediate these risks on a priority basis wherever possible.

      One  of  Samson   Investment   Company's   Executive  Vice  Presidents  is
      responsible  for  communicating  to its Board of Directors Y2K actions and
      for the  ultimate  implementation  of its Y2K plan.  He has  delegated  to
      Samson   Investment   Company's  Senior  Vice   President-Technology   and
      Administrative Services principal responsibility
      for ensuring Y2K compliance within Samson.

      Samson  has  been  planning  for  the  impact  of Y2K  on its  information
      technology systems since 1993. As of July 15, 1999, Samson is in the final
      stages of implementation of a Y2K plan, as summarized below:

      FINANCIAL AND ADMINISTRATIVE SYSTEMS

      1. Awareness. Samson has alerted its officers, managers and supervisors of
      Y2K  issues  and asked them to have  their  employees  participate  in the
      identification  of potential Y2K risks which might  otherwise go unnoticed
      by higher level  employees  and  officers.  As a result,  awareness of the
      issue is considered high.

      2.  Risk   Identification.   Samson's  most   significant   financial  and
      administrative  systems  exposure is the Y2K status of the  accounting and
      land  administration  system used to collect and manage data for  internal
      management  decision making and for external  revenue and accounts payable
      purposes.  Other concerns include network  hardware and software,  desktop
      computing  hardware  and  software,  telecommunications,  and office space
      readiness.

      3. Risk  Assessment.  The failure to identify  and correct a material  Y2K
      problem could result in inaccurate or untimely  financial  information for
      management  decision-making  or cash flow and payment purposes,  including
      maintaining oil and gas leases.

      4.  Remediation.  Since 1993, Samson has been upgrading its accounting and
      land administration  software.  Substantially all of the Y2K upgrades have
      been completed,  with the remainder  scheduled to be completed  during the
      3rd quarter of 1999.  In  addition,  in 1997 and 1998  Samson  replaced or
      applied software patches to substantially all of its network




                                      -48-





      and desktop  software  applications  and believes them to be generally Y2K
      compliant.  Additional  patches or  software  upgrades  will be applied no
      later than  September 30, 1999 to complete this process.  The costs of all
      such risk  assessments  and remediation are not expected to be material to
      the Partnerships.

      5. Contingency  Planning.  Notwithstanding the foregoing,  should there be
      significant   unanticipated   disruptions   in  Samson's   financial   and
      administrative systems, all of the accounting processes that are currently
      automated will need to be performed  manually.  Samson has communicated to
      its management  team the importance of having  adequate staff available to
      manually perform necessary functions to minimize disruptions.


      IMBEDDED SYSTEMS

      1.  Awareness.  Samson's  Y2K  program  has  involved  all levels of field
      personnel from production  foremen and higher.  Employees at all levels of
      the organization  have been asked to participate in the  identification of
      potential  Y2K risks,  which might  otherwise go unnoticed by higher level
      employees and officers of Samson, and as a result,  awareness of the issue
      is considered high.

      2. Risk  Identification.  Samson has inventoried all possible exposures to
      imbedded chips and systems. Such exposures can be classified as either (i)
      oil and gas production and  processing  equipment or (ii) office  machines
      such as faxes, copiers, phones, etc.

      With respect to oil and gas production and processing  equipment,  neither
      Samson nor the Partnerships operate offshore wells, significant processing
      plants, or wells with older electronic  monitoring  systems.  As a result,
      Samson's  inventory  identified less than 10  applications  using imbedded
      chips.  All of these have been tested by the  respective  vendors and have
      been found to be Y2K compliant or have been upgraded or replaced.

      Office machines have been tested by Samson and vendors and are believed to
      be compliant.

      3. Risk Assessment and Remediation.  The failure to identify and correct a
      material  Y2K  problem in an  imbedded  system  could  result in  outcomes
      ranging  from errors in data  reporting  to  curtailments  or shutdowns in
      production.  As noted above,  Samson has identified  less than 10 imbedded
      system  applications  all of which have been made  compliant  or replaced.
      None of these  applications  are  believed to be material to Samson or the
      Partnerships. Samson believes




                                      -49-





      that sufficient manual processes are available to minimize any field level
      risk and that there will be no material  impact on the  Partnerships  with
      respect to these applications.

      4. Contingency Planning. Should material production disruptions occur as a
      result of Y2K  failures  in field  operations,  Samson  will  utilize  its
      existing  field  personnel in an attempt to avoid any  material  impact on
      operating cash flow. Samson is not able to quantify any potential exposure
      in the event of systems failure or inadequate manual alternatives.


      THIRD PARTY EXPOSURES

      1. Awareness.  Samson has advised  management to consider Y2K implications
      with its outside vendors, customers, and business partners. Management has
      been asked to participate in the  identification  of potential third party
      Y2K risks and, as a result, awareness of the issue is considered high.

      2. Risk Identification. Samson's most significant third party Y2K exposure
      is its  dependence  on third  parties for the receipt of revenues from oil
      and gas sales.  However,  virtually all of these purchasers are very large
      and sophisticated  companies.  Other Y2K concerns include the availability
      of  electric  power  to  Samson's  field  operations,   the  integrity  of
      telecommunication  systems,  and the  readiness  of  commercial  banks  to
      execute electronic fund transfers.

      3. Risk  Assessment.  Because of the high  awareness of the Y2K problem in
      the U.S.,  Samson  has not  undertaken  and does not plan to  undertake  a
      formal company wide plan to make inquiries of third parties on the subject
      of Y2K readiness. If it did so, Samson has no ability to require responses
      to such inquiries or to independently  verify their accuracy.  Samson has,
      however,  received  oral  assurances  from  its  significant  oil  and gas
      purchasers  of Y2K  compliance.  If  significant  disruptions  from  major
      purchasers were to occur,  however,  there could be a material and adverse
      impact  on  the  Partnerships'  results  of  operations,   liquidity,  and
      financial conditions.

      It is  important  to note that  third  party oil and gas  purchasers  have
      significant  incentives to avoid  disruptions  arising from a Y2K failure.
      For example,  most of these parties are under  contractual  obligations to
      purchase oil and gas or disperse revenues to Samson.  The failure to do so
      will result in  contractual  and statutory  penalties.  Therefore,  Samson
      believes  that it is  unlikely  that there will be  material  third  party
      non-compliance with purchase and remittance obligations as a result of Y2K
      issues.




                                      -50-






      4.   Remediation.   Where  Samson   perceives   significant  risk  of  Y2K
      non-compliance  that may have a  material  impact  on it,  and  where  the
      relationship  between Samson and a vendor,  customer,  or business partner
      permits,  joint testing may be undertaken  during the remainder of 1999 to
      further identify these risks.

      5. Contingency  Planning.  In the unlikely event that material  production
      disruptions  occur as a result  of Y2K  failures  of  third  parties,  the
      Partnerships' operating cash flow could be impacted. This contingency will
      be  factored   into   deliberations   on  the  level  of  quarterly   cash
      distributions paid out during any such period of cash flow disruption.

ITEM 3.     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET
            RISK.

            The Partnerships do not hold any market risk sensitive instruments.
