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

      The combined  balance sheets as of June 30, 1998,  combined  statements of
      operations  for the three and six months ended June 30, 1998 and 1997, and
      combined  statements  of cash flows for the six months ended June 30, 1998
      and 1997 have been  prepared  by  Geodyne  Resources,  Inc.,  the  General
      Partner  of  the  limited   partnerships,   without  audit.  Each  limited
      partnership  is a general  partner in the related  Geodyne  Energy  Income
      Production  Partnership  in which Geodyne  Resources,  Inc.  serves as the
      managing partner.  Unless the context indicates otherwise,  all references
      to a  "Partnership"  or the  "Partnerships"  are references to the limited
      partnership and its related production partnership,  collectively, and all
      references to the "General  Partner" are references to the general partner
      of the limited  partnerships  and the managing  partner of the  production
      partnerships,  collectively.  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, 1998,  the  combined  results of  operations  for the
      three and six months ended June 30, 1998 and 1997,  and the combined  cash
      flows for the six months ended June 30, 1998 and 1997.

      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, 1997. The
      results  of  operations  for  the  period  ended  June  30,  1998  are not
      necessarily indicative of the results to be expected for the full year.

      The  Limited  Partners'  net  income  or loss per unit is based  upon each
      $1,000 initial capital contribution.





                                       22




      OIL AND GAS PROPERTIES
      ----------------------

      The  Partnerships  follow the successful  efforts method of accounting for
      their oil and gas properties.  Under the successful  efforts  method,  the
      Partnerships  capitalize all property  acquisition  costs and  development
      costs incurred in connection  with the further  development of oil and gas
      reserves.  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  Partnerships of
      properties  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.  Leasehold impairment
      is recognized based upon an individual property assessment and exploratory
      experience.  Upon discovery of commercial  reserves,  leasehold  costs are
      transferred to producing properties.

      Depletion of the costs of producing oil and gas  properties,  amortization
      of related intangible  drilling and development costs, and depreciation of
      tangible lease and well  equipment are computed on the  unit-of-production
      method.  The  Partnerships'  depletion,   depreciation,  and  amortization
      includes  estimated  dismantlement and abandonment costs, net of estimated
      salvage value.

      When complete units of depreciable property are retired or sold, the asset
      cost and related accumulated  depreciation are eliminated with any gain or
      loss  reflected in income.  When less than complete  units of  depreciable
      property  are  retired  or sold,  the  difference  between  asset cost and
      salvage value is charged to accumulated depreciation.





                                       23




      Statement of Financial  Accounting Standards ("SFAS") No. 121, "Accounting
      for the  Impairment  of Long Lived  Assets and Assets Held for  Disposal",
      requires successful efforts companies, like the Partnerships,  to evaluate
      the  recoverability  of the  carrying  costs of their  proved  oil and gas
      properties at the lowest level for which there are identifiable cash flows
      that are largely  independent of the cash flows of other groups of oil and
      gas properties.  With respect to the Partnerships' oil and gas properties,
      this evaluation was performed for each field.  SFAS No. 121, provides that
      if the  unamortized  costs of oil and gas properties for each field exceed
      the expected undiscounted future cash flows from such properties, the cost
      of the  properties  is written down to fair value,  which is determined by
      using  the  discounted   future  cash  flows  from  the  properties.   The
      Partnerships  recorded  a non-cash  charge  against  earnings  (impairment
      provision)  during the six months ended June 30, 1997 pursuant to SFAS No.
      121 as follows:

                  Partnership               Amount
                  -----------             -----------
                    I-B                    $ 19,726
                    I-C                       4,679
                    I-D                      61,790
                    I-E                     291,690
                    I-F                     114,631

      No such charge was  recorded in the six months  ended June 30,  1998.  The
      risk that the  Partnerships  will be required  to record  such  impairment
      provisions in the future increases when oil and gas prices are depressed.

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, 1998 the  following  payments were made to the

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  and operating
      producing oil and gas properties located in the continental United States.
      In general, a Partnership acquired producing properties and did not engage
      in  development  drilling  or  enhanced  recovery  projects,  except as an
      incidental  part of the management of the producing  properties  acquired.
      Therefore,  the  economic  life  of  each  Partnership,  and  its  related
      Production Partnership, is limited to the period of time required to fully
      produce its acquired oil and gas  reserves.  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.



                                       26




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
              -----------     ------------------        ---------------

                 I-B          July 12, 1985               $11,957,700
                 I-C          December 20, 1985             8,884,900
                 I-D          March 4, 1986                 7,194,700
                 I-E          September 10, 1986           41,839,400
                 I-F          December 16, 1986            14,320,900

      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  operations  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,  1998  and  the  net  revenue
      generated from future operations will provide  sufficient  working capital
      to meet current and future obligations.

      The  Partnerships'  Statements of Cash Flows for the six months ended June
      30, 1998 include  proceeds from the sale of oil and gas properties  during
      the six months ended June 30, 1998.  These  proceeds  received  during the
      first quarter were included in the Partnerships'  cash  distributions paid
      during May 1998, and the proceeds  received during the second quarter will
      be included in the Partnerships'  cash  distributions to be paid in August
      1998. It is possible that the  Partnerships'  repurchase values and future
      cash  distributions  could decline as a result of the disposition of these
      properties.  On the other hand, the General Partner believes there will be
      beneficial operating  efficiencies related to the Partnerships'  remaining
      properties.  This is primarily  due to the fact that the  properties  sold
      generally  bore a higher  ratio  of  operating  expenses  as  compared  to
      reserves than the Partnerships' remaining properties.




                                       27




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.  Predicting  future  prices  is very  difficult.
      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 are at or near their lowest level
      in the past  decade  due  primarily  to the  global  surplus of crude oil.
      Management is unable to predict whether future oil and gas prices will (i)
      stabilize, (ii) increase, or (iii) decrease.

      I-B PARTNERSHIP

      THREE  MONTHS  ENDED JUNE 30, 1998 AS COMPARED TO THE THREE  MONTHS  ENDED
      JUNE 30, 1997.

                                                ---------------------------
                                                    1998             1997
                                                  -------          --------
      Oil and gas sales                           $59,328          $109,096
      Oil and gas production expenses             $16,796          $ 37,612
      Barrels produced                                265               527
      Mcf produced                                 28,541            37,735
      Average price/Bbl                           $ 11.15          $  18.83
      Average price/Mcf                           $  1.98          $   2.63

      As shown in the table  above,  total oil and gas sales  decreased  $49,768
      (45.6%) for the three  months ended June 30, 1998 as compared to the three
      months ended June 30, 1997.  Of this  decrease,  approximately  $5,000 and
      $24,000, respectively, were related to decreases in volumes of oil and gas
      sold and approximately $2,000 and $19,000,  respectively,  were related to
      decreases  in the average  prices of oil and gas sold.  Volumes of oil and
      gas sold decreased 262 barrels and 9,194 Mcf, respectively,  for the three
      months  ended June 30, 1998 as compared to the three months ended June 30,
      1997. The decrease in volumes of oil sold resulted  primarily from (i) the
      sale  of one  significant  well in  1997  and  (ii) a  normal  decline  in
      production due to diminishing  reserves on one significant well during the
      three  months  ended June 30,  1998.  The  decrease in volumes of gas sold
      resulted primarily



                                       28




      from (i) positive  prior period  volume  adjustments  by purchasers on two
      significant  wells during the three  months ended June 30, 1997,  (ii) the
      sale of one  significant  well in  1997,  and  (iii) a normal  decline  in
      production due to diminishing  reserves on one significant well during the
      three months ended June 30, 1998.  Average oil and gas prices decreased to
      $11.15 per barrel and $1.98 per Mcf,  respectively,  for the three  months
      ended  June  30,   1998  from   $18.83  per  barrel  and  $2.63  per  Mcf,
      respectively, for the three months ended June 30, 1997.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes)  decreased  $20,816  (55.3%) for the three months ended
      June 30, 1998 as compared to the three months  ended June 30,  1997.  This
      decrease  resulted  primarily  from (i) a  decrease  in  production  taxes
      associated  with the decrease in oil and gas sales discussed  above,  (ii)
      the  decreases  in volumes of oil and gas sold during the six months ended
      June 30,  1998 as compared to the six months  ended June 30,  1997,  (iii)
      workover  expenses  incurred  on two  significant  wells  during the three
      months  ended June 30, 1997 in order to improve the  recovery of reserves,
      and (iv) the sale of one significant  well in 1997. As a percentage of oil
      and gas sales,  these  expenses  decreased  to 28.3% for the three  months
      ended June 30, 1998 from 34.5% for the three  months  ended June 30, 1997.
      This  percentage  decrease was  primarily  due to the decrease in workover
      expenses discussed above.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      decreased  $3,785  (24.7%)  for the three  months  ended June 30,  1998 as
      compared to the three months ended June 30, 1997.  This decrease  resulted
      primarily  from the  decreases  in volumes of oil and gas sold  during the
      three  months  ended June 30, 1998 as compared to the three  months  ended
      June 30 1997. As a percentage of oil and gas sales, this expense increased
      to 19.5% for the three months ended June 30, 1998 from 14.1% for the three
      months ended June 30, 1997. This percentage  increase was primarily due to
      the  decreases in the average  prices of oil and gas sold during the three
      months  ended June 30, 1998 as compared to the three  months ended June 30
      1997.

      General and administrative expenses decreased $4,798 (27.1%) for the three
      months  ended June 30, 1998 as compared to the three months ended June 30,
      1997.  This decrease  resulted  primarily from a decrease in  professional
      fees for the three  months  ended June 30,  1998 as  compared to the three
      months ended June 30, 1997.  As a percentage  of oil and gas sales,  these
      expenses  increased to 21.7% for the three months ended June 30, 1998 from
      16.2% for the three months ended June 30, 1997. This  percentage  increase
      was primarily due to the decrease in oil and gas sales discussed above.

      Average price/Bbl                           $  13.17         $  20.01
      Average price/Mcf                           $   2.09         $   2.46

      As shown in the table  above,  total oil and gas sales  decreased  $71,338
      (37.2%)  for the six months  ended June 30,  1998 as  compared  to the six
      months ended June 30, 1997.  Of this  decrease,  approximately  $7,000 and
      $39,000, respectively, were related to decreases in volumes of oil and gas
      sold and approximately $5,000 and $20,000,  respectively,  were related to
      decreases  in the average  prices of oil and gas sold.  Volumes of oil and
      gas sold  decreased  377 barrels  and 15,809 Mcf for the six months  ended
      June 30,  1998 as  compared  to the six months  ended June 30,  1997.  The
      decrease in volumes of oil sold  resulted  primarily  from (i) the sale of
      one  significant  well in 1997 and (ii) a normal decline in production due
      to  diminishing  reserves  on one  significant  well during the six months
      ended  June 30,  1998.  The  decrease  in  volumes  of gas  sold  resulted
      primarily  from  (i) the  sale of two  significant  wells in 1997 and (ii)
      positive  prior period volume  adjustments  by purchasers on several wells
      during the six  months  ended June 30,  1997.  Average  oil and gas prices
      decreased  to $13.17 per barrel and $2.09 per Mcf,  respectively,  for the
      six months  ended June 30,  1998 from $20.01 per barrel and $2.46 per Mcf,
      respectively, for the six months ended June 30, 1997.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes) decreased $25,450 (41.5%) for the six months ended June
      30, 1998 as compared to the six months ended June 30, 1997.  This decrease
      resulted primarily from (i) a decrease in production taxes associated with
      the decrease in oil and gas sales discussed  above,  (ii) the decreases in
      volumes of oil and gas sold  during the six months  ended June 30, 1998 as
      compared  to the six  months  ended  June 30,  1997,  and  (iii)  workover
      expenses on one  significant  well during the three  months ended June 30,
      1997. As a percentage of oil and gas sales,  these  expenses  decreased to
      29.9% for the six months ended June 30, 1998 from 32.1% for the six months
      ended June 30, 1997.  This  percentage  decrease was  primarily due to the
      decrease in workover expenses discussed above.



                                       30





      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      decreased  $6,299  (22.3%)  for the six  months  ended  June  30,  1998 as
      compared to the six months ended June 30,  1997.  This  decrease  resulted
      primarily  from the decrease in volumes of oil and gas sold during the six
      months  ended June 30, 1998 as  compared  to the six months  ended June 30
      1997.  As a percentage  of oil and gas sales,  this  expense  increased to
      18.3% for the six months ended June 30, 1998 from 14.8% for the six months
      ended June 30, 1997.  This  percentage  increase was  primarily due to the
      decreases in the average  prices of oil and gas sold during the six months
      ended June 30, 1998 as compared to the six months ended June 30, 1997.

      The I-B  Partnership  recognized  a non-cash  charge  against  earnings of
      $19,726 during the six months ended June 30, 1997. Of this amount, $17,233
      was  related to the decline in oil and gas prices  used to  determine  the
      recoverability of proved oil and gas reserves at March 31, 1997 and $2,493
      was  related to the writing off of  unproved  properties.  These  unproved
      properties were written off based on the General  Partner's  determination
      that it was unlikely  that such  properties  would be developed due to the
      low  oil and  gas  prices  received  over  the  prior  several  years  and
      provisions in the I-B Partnership's  partnership agreement which limit the
      level of permissible  drilling  activity.  No similar charge was necessary
      during the three months ended June 30, 1998.

      General and  administrative  expenses  decreased $2,410 (6.6%) for the six
      months  ended June 30, 1998 as  compared to the six months  ended June 30,
      1997. As a percentage of oil and gas sales,  these  expenses  increased to
      28.3%  for the six  months  ended  June 30,  1998  from 19.0 % for the six
      months ended June 30, 1997. This percentage  increase was primarily due to
      the decrease in oil and gas sales discussed above.

      The Limited  Partners have received  cash  distributions  through June 30,
      1998  totaling   $6,650,527  or  55.62%  of  Limited   Partners'   capital
      contributions.

      Average price/Mcf                           $  1.90          $   2.64

      As shown in the table above,  total oil and gas sales  decreased  $110,709
      (53.6%) for the three  months ended June 30, 1998 as compared to the three
      months ended June 30, 1997. Of this  decrease,  approximately  $40,000 and
      $24,000, respectively, were related to decreases in volumes of oil and gas
      sold and approximately $23,000 and $23,000, respectively,  were related to
      decreases  in the average  prices of oil and gas sold.  Volumes of oil and
      gas sold  decreased  2,145  barrels and 9,159 Mcf,  respectively,  for the
      three  months  ended June 30, 1998 as compared to the three  months  ended
      June 30, 1997. The decrease in volumes of oil sold resulted primarily from
      the sale of one  significant  well during 1997. The decrease in volumes of
      gas sold  resulted  primarily  from a normal  decline in production on one
      significant well during the three months ended June 30, 1998.  Average oil
      and gas  prices  decreased  to  $11.45  per  barrel  and  $1.90  per  Mcf,
      respectively,  for the three  months  ended June 31,  1998 from $18.78 per
      barrel and $2.64 per Mcf,  respectively,  for the three  months ended June
      30, 1997.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes)  decreased  $40,841  (43.2%) for the three months ended
      June 30, 1998 as compared to the three months  ended June 30,  1997.  This
      decrease  was  primarily  due  to  (i)  a  decrease  in  production  taxes
      associated  with the decrease in oil and gas sales discussed  above,  (ii)
      the  decreases  in volumes of oil and gas sold for the three  months ended
      June 30, 1998 as compared to the three  months  ended June 30,  1997,  and
      (iii)  workover  expenses  incurred on three wells during the three months
      ended June 30, 1997 in order to improve the  recovery  of  reserves.  As a
      percentage of oil and gas sales, these expenses increased to 56.0% for the
      three  months  ended June 30, 1998 from 45.8% for the three  months  ended
      June 30, 1997. This percentage increase was primarily due to the decreases
      in the average prices of oil and gas sold for the



                                       32




      three  months  ended June 30, 1998 as compared to the three  months  ended
      June 30, 1997.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      decreased  $5,112  (47.6%)  for the three  months  ended June 30,  1998 as
      compared to the three months ended June 30, 1997.  This decrease  resulted
      primarily  from the  decreases  in volumes of oil and gas sold  during the
      three  months  ended June 30, 1998 as compared to the three  months  ended
      June 30, 1997. As a percentage of oil and gas sales, this expense remained
      relatively  constant at 5.9% for the three  months ended June 30, 1998 and
      5.2% for the three months ended June 30, 1997.

      General and administrative expenses decreased $3,527 (12.6%) for the three
      months  ended June 30, 1998 as compared to the three months ended June 30,
      1997.  This  decrease was  primarily  due to decreased  professional  fees
      during the three  months  ended  June 30,  1998 as  compared  to the three
      months ended June 30, 1997.  As a percentage  of oil and gas sales,  these
      expenses  increased to 25.7% for the three months ended June 30, 1998 from
      13.6% for the three months ended June 30, 1997. This  percentage  increase
      was primarily due to the decrease in oil and gas sales discussed above.

      As shown in the table above,  total oil and gas sales  decreased  $189,880
      (40.2%)  for the six months  ended June 30,  1998 as  compared  to the six
      months ended June 30, 1997. Of this  decrease,  approximately  $77,000 and
      $49,000, respectively, were related to decreases in volumes of oil and gas
      sold and approximately $55,000 and $9,000,  respectively,  were related to
      decreases  in the average  prices of oil and gas sold.  Volumes of oil and
      gas sold decreased 3,840 barrels and 17,562 Mcf, respectively, for the six
      months  ended June 30, 1998 as  compared to the six months  ended June 30,
      1997. The decrease in volumes of oil sold resulted primarily from the sale
      of one  significant  well during 1997. The decrease in volumes of gas sold
      resulted  primarily  from  a  normal  decline  in  production  on  another
      significant well during the six months ended June

      30,  1998.  Average oil and gas prices  decreased to $12.45 per barrel and
      $2.64 per Mcf,  respectively,  for the six months ended June 30, 1998 from
      $19.94  per  barrel  and $2.77 per Mcf,  respectively,  for the six months
      ended June 30, 1997.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes) decreased $40,109 (26.5%) for the six months ended June
      30, 1998 as compared to the six months ended June 30, 1997.  This decrease
      was primarily due to (i) a decrease in production  taxes  associated  with
      the decrease in oil and gas sales  discussed  above and (ii) the decreases
      in volumes of oil and gas sold for the six months  ended June 30,  1998 as
      compared to the six months ended June 30, 1997. As a percentage of oil and
      gas sales, these expenses increased to 39.4% for the six months ended June
      30,  1998  from  32.0%  for the six  months  ended  June  30,  1997.  This
      percentage  increase  was  primarily  due to the  decreases in the average
      prices  of oil and gas  sold for the six  months  ended  June 30,  1998 as
      compared to the six months ended June 30, 1997.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      decreased  $10,290  (44.2%)  for the six  months  ended  June 30,  1998 as
      compared to the six months ended June 30,  1997.  This  decrease  resulted
      primarily from the decreases in volumes of oil and gas sold during the six
      months  ended June 30, 1998 as  compared to the six months  ended June 30,
      1997.  As a  percentage  of oil  and  gas  sales,  this  expense  remained
      relatively  constant  at 4.6% for the six months  ended June 30,  1998 and
      4.9% for the six months ended June 30, 1997.

      The I-C  Partnership  recognized  a non-cash  charge  against  earnings of
      $4,679 during the six months ended June 30, 1997 primarily  related to the
      decline in oil and gas prices  used to  determine  the  recoverability  of
      proved oil and gas  reserves  at March 31,  1997.  No  similar  charge was
      necessary during the six months ended June 30, 1998.

      General and  administrative  expenses  decreased $1,906 (3.3%) for the six
      months  ended June 30, 1998 as  compared to the six months  ended June 30,
      1997. As a percentage of oil and gas sales,  these  expenses  increased to
      19.6% for the six months ended June 30, 1998 from 12.1% for the six months
      ended June 30, 1997.  This  percentage  increase was  primarily due to the
      decrease in oil and gas sales discussed above.

      The Limited  Partners have received  cash  distributions  through June 30,
      1998  totaling   $8,131,300  or  91.52%  of  Limited   Partners'   capital
      contributions.

      As shown in the table above,  total oil and gas sales  decreased  $145,475
      (43.8%) for the three  months ended June 30, 1998 as compared to the three
      months ended June 30, 1997. Of this  decrease,  approximately  $14,000 and
      $97,000, respectively, were related to decreases in volumes of oil and gas
      sold and approximately $18,000 and $16,000, respectively,  were related to
      decreases  in the average  prices of oil and gas sold.  Volumes of oil and
      gas sold decreased 787 barrels and 45,623 Mcf, respectively, for the three
      months  ended June 30, 1998 as compared to the three months ended June 30,
      1997. The decrease in volumes of oil sold resulted primarily from a normal
      decline in  production  on one  significant  well during the three  months
      ended  June 30,  1998.  The  decrease  in  volumes  of gas  sold  resulted
      primarily from normal  declines in production on three  significant  wells
      during the three months  ended June 30,  1998.  Average oil and gas prices
      decreased  to $11.95 per barrel and $1.93 per Mcf,  respectively,  for the
      three months ended June 30, 1998 from $17.98 per barrel and $2.14 per Mcf,
      respectively, for the three months ended June 30, 1997.

      As discussed in Liquidity and Capital Resources above, the I-D Partnership
      sold certain oil and gas properties during the three months ended June 30,
      1998 and  recognized a $108,746  gain on such sales.  Similar sales during
      the three  months  ended June 30,  1997  resulted  in the I-D  Partnership
      recognizing similar gains totaling $15,824.




                                       35







      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes)  decreased  $27,494  (40.5%) for the three months ended
      June 30, 1998 as compared to the three months  ended June 30,  1997.  This
      decrease  resulted  primarily  from (i) a  decrease  in  production  taxes
      associated with the decrease in oil and gas sales discussed above and (ii)
      the  decreases  in volumes of oil and gas sold for the three  months ended
      June 30, 1998 as compared to the three months  ended June 30,  1997.  As a
      percentage  of oil and  gas  sales,  these  expenses  remained  relatively
      constant at 21.6% for the three  months  ended June 30, 1998 and 20.4% for
      the three months ended June 30, 1997.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      decreased  $16,871  (59.0%)  for the three  months  ended June 30, 1998 as
      compared to the three months ended June 30, 1997.  This decrease  resulted
      primarily from (i) the decreases in volumes of oil and gas sold during the
      three months ended June 3, 1998 as compared to the three months ended June
      30, 1997 and (ii) upward  revisions in the  estimates of remaining oil and
      gas reserves at December 31, 1997.  As a percentage  of oil and gas sales,
      this  expense  decreased  to 6.3% for the three months ended June 30, 1998
      from  8.6% for the three  months  ended  June 30,  1997.  This  percentage
      decrease was  primarily  due to the upward  revisions in the  estimates of
      remaining oil and gas reserves discussed above.

      General and administrative expenses decreased $3,196 (12.8%) for the three
      months  ended June 30, 1998 as compared to the three months ended June 30,
      1997.  This decrease was primarily a result of a decrease in  professional
      fees during the three  months ended June 30, 1998 as compared to the three
      months ended June 30, 1997.  As a percentage  of oil and gas sales,  these
      expenses  increased to 11.6% for the three months ended June 30, 1998 from
      7.5% for the three months ended June 30, 1997.  This  percentage  increase
      was primarily due to the decrease in oil and gas sales discussed above.

      As shown in the table above,  total oil and gas sales  decreased  $324,732
      (40.3%)  for the six months  ended June 30,  1998 as  compared  to the six
      months ended June 30, 1997. Of this  decrease,  approximately  $45,000 and
      $169,000,  respectively,  were  related to decreases in volumes of oil and
      gas sold and approximately $47,000 and $64,000, respectively, were related
      to decreases in the average prices of oil and gas sold. Volumes of oil and
      gas sold decreased 2,186 barrels and 69,298 Mcf, respectively, for the six
      months  ended June 30, 1998 as  compared to the six months  ended June 30,
      1997.  The decrease in volumes of oil sold resulted  primarily from normal
      declines in  production  on two  significant  wells  during the six months
      ended  June 30,  1998.  The  decrease  in  volumes  of gas  sold  resulted
      primarily  from normal  declines in production on several wells during the
      six months  ended June 30, 1998.  Average oil and gas prices  decreased to
      $13.23  per  barrel  and $2.10 per Mcf,  respectively,  for the six months
      ended  June  30,   1998  from   $20.66  per  barrel  and  $2.44  per  Mcf,
      respectively, for the six months ended June 30, 1997.

      As discussed in Liquidity and Capital Resources above, the I-D Partnership
      sold certain oil and gas  properties  during the six months ended June 30,
      1998 and  recognized a $255,796  gain on such sales.  Similar sales during
      the six  months  ended  June  30,  1997  resulted  in the I-D  Partnership
      recognizing similar gains totaling $15,824.




                                       37





      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes) decreased $38,753 (30.3%) for the six months ended June
      30, 1998 as compared to the six months ended June 30, 1997.  This decrease
      resulted primarily from (i) a decrease in production taxes associated with
      the decrease in oil and gas sales  discussed  above and (ii) the decreases
      in volumes of oil and gas sold  during the six months  ended June 30, 1998
      as compared to June 30, 1997. As a percentage of oil and gas sales,  these
      expenses  increased  to 18.6% for the six months  ended June 30, 1998 from
      15.9% for the six months ended June 30, 1997. This percentage increase was
      primarily due to the  decreases in the average  prices of oil and gas sold
      during the six months  ended June 30,  1998 as  compared to the six months
      ended June 30, 1997.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      decreased  $32,699  (54.2%)  for the six  months  ended  June 30,  1998 as
      compared to the six months ended June 30,  1997.  This  decrease  resulted
      primarily from (i) the decreases in volumes of oil and gas sold during the
      six months  ended June 30, 1998 as  compared to the six months  ended June
      30, 1997 and (ii) upward  revisions in the  estimates of remaining oil and
      gas reserves at December 31, 1997.  As a percentage  of oil and gas sales,
      this expense decreased to 5.7% for the six months ended June 30, 1998 from
      7.5% for the six months ended June 30, 1997.

      The I-D  Partnership  recognized  a non-cash  charge  against  earnings of
      $61,790 during the six months ended June 30, 1998. Of this amount, $12,290
      was  related to the decline in oil and gas prices  used to  determine  the
      recoverability  of  proved  oil and gas  reserves  at March  31,  1997 and
      $49,500  was related to the  writing  off of  unproved  properties.  These
      unproved  properties  were  written  off  based on the  General  Partner's
      determination that it was unlikely that such properties would be developed
      due to the low oil and gas prices  received  over the prior  several years
      and provisions in the I-D Partnership's  partnership agreement which limit
      the  level  of  permissible  drilling  activity.  No  similar  charge  was
      necessary during the six months ended June 30, 1998.

      General and  administrative  expenses  decreased $1,800 (3.6%) for the six
      months  ended June 30, 1998 as  compared to the six months  ended June 30,
      1997. As a percentage of oil and gas sales,  these  expenses  increased to
      9.9% for the six months  ended June 30,  1998 from 6.1% for the six months
      ended June 30, 1997.  This  percentage  increase was  primarily due to the
      decrease in oil and gas sales discussed above.

      The Limited  Partners have received  cash  distributions  through June 30,
      1998  totaling   $13,496,175  or  187.58%  of  Limited  Partners'  capital
      contributions.

      As shown in the table above,  total oil and gas sales  decreased  $433,002
      (29.7%) for the three  months ended June 30, 1998 as compared to the three
      months ended June 30, 1997. Of this  decrease,  approximately  $42,000 and
      $174,000,  respectively,  were  related to decreases in volumes of oil and
      gas  sold and  approximately  $122,000  and  $95,000,  respectively,  were
      related to decreases in the average prices of oil and gas sold. Volumes of
      oil and gas sold decreased 2,290 barrels and 82,417 Mcf, respectively, for
      the three months ended June 30, 1998 as compared to the three months ended
      June 30, 1997. The decrease in volumes of oil sold resulted primarily from
      (i) normal  declines in  production  on two  significant  wells during the
      three months ended June 30, 1998 and (ii) the sale of one significant well
      in 1997.  The  decrease  in volumes of gas sold  resulted  primarily  from
      normal  declines in production on two  significant  wells during the three
      months ended June 30, 1998. Average oil and gas prices decreased to $11.53
      per barrel and $1.89 per Mcf,  respectively,  for the three  months  ended
      June 30, 1998 from $18.39 per barrel and $2.11 per Mcf, respectively,  for
      the three months ended June 30, 1997.

      As discussed in Liquidity and Capital Resources above, the I-E Partnership
      sold certain oil and gas properties during the three months ended June 30,
      1998 and  recognized a $489,455  gain on such sales.  Similar sales during
      the three  months  ended June 30,  1997  resulted  in the I-E  Partnership
      recognizing similar gains totaling $62,609.



                                       39





      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes)  decreased  $120,163 (27.8%) for the three months ended
      June 30, 1998 as compared to the three months  ended June 30,  1997.  This
      decrease  resulted  primarily  from (i) a  decrease  in  production  taxes
      associated  with the decrease in oil and gas sales discussed  above,  (ii)
      the decreases in volumes of oil and gas sold during the three months ended
      June 30, 1998 as compared to the three  months  ended June 30,  1997,  and
      (iii) decreased general repair and maintenance expenses on two significant
      wells during the three months ended June 30, 1998 as compared to the three
      months ended June 30, 1997.  As a percentage  of oil and gas sales,  these
      expenses  increased to 30.4% for the three months ended June 30, 1998 from
      29.6% for the three months ended June 30, 1997. This  percentage  increase
      was primarily  due to the  decreases in the average  prices of oil and gas
      sold during the three  months ended June 30, 1998 as compared to the three
      months ended June 30, 1997,  which  increase was  partially  offset by the
      decreased general repair and maintenance expenses discussed above.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      decreased  $42,180  (20.9%)  for the three  months  ended June 30, 1998 as
      compared to the three months ended June 30, 1997.  This decrease  resulted
      primarily from (i) the decreases in volumes of oil and gas sold during the
      three  months  ended June 30, 1998 as compared to the three  months  ended
      June 30, 1997 and (ii) upward  revisions in the estimates of remaining gas
      reserves at December 31, 1997. As a percentage of oil and gas sales,  this
      expense  increased  to 15.6% for the three months ended June 30, 1998 from
      13.8% for the three months ended June 30, 1997.

      General and  administrative  expenses  decreased  $17,804  (12.7%) for the
      three  months  ended June 30, 1998 as compared to the three  months  ended
      June  30,  1997.  This  decrease  was  primarily  due  to  a  decrease  in
      professional  fees during the three months ended June 30, 1998 as compared
      to the three months ended June 30,  1997.  As a percentage  of oil and gas
      sales,  these expenses  increased to 11.9% for the three months ended June
      30,  1998  from  9.6% for the  three  months  ended  June 30,  1997.  This
      percentage increase was primarily due to the decrease in oil and gas sales
      discussed above.

      As shown in the table above, total oil and gas sales decreased  $1,119,376
      (34.9%)  for the six months  ended June 30,  1998 as  compared  to the six
      months ended June 30, 1997. Of this decrease,  approximately  $108,000 and
      $399,000,  respectively,  were  related to decreases in volumes of oil and
      gas sold and  approximately  $253,000  and  $359,000,  respectively,  were
      related to decreases in the average prices of oil and gas sold. Volumes of
      oil and gas sold  decreased  5,249 barrels and 170,288 Mcf,  respectively,
      for the six months ended June 30, 1998 as compared to the six months ended
      June 30, 1997. The decrease in volumes of oil sold resulted primarily from
      (i) the sale of one  significant  well in 1997 and (ii) normal declines in
      production on several wells during the six months ended June 30, 1998. The
      decrease  in volumes of gas sold  resulted  primarily  from (i) a negative
      prior period volume  adjustment  made by the purchaser on one  significant
      well during the six months ended June 30, 1998 and (ii) normal declines in
      production  on several  wells during the six months ended June 30, 1998 as
      compared to the six months ended June 30, 1997. Average oil and gas prices
      decreased  to $13.15 per barrel and $1.92 per Mcf,  respectively,  for the
      six months  ended June 30,  1998 from $20.63 per barrel and $2.34 per Mcf,
      respectively, for the six months ended June 30, 1997.

      As discussed in Liquidity and Capital Resources above, the I-E Partnership
      sold certain oil and gas  properties  during the six months ended June 30,
      1998 and recognized a $1,149,051 gain on such sales.  Similar sales during
      the six  months  ended  June  30,  1997  resulted  in the I-E  Partnership
      recognizing similar gains totaling $62,609.

      Oil and gas production  expenses  (including lease operating  expenses and
      production taxes) decreased $210,553 (25.9%) for the six months ended June
      30, 1998 as compared to the six months ended June 30, 1997.  This decrease
      resulted primarily from (i) a decrease in production taxes associated with
      the decrease in oil and gas sales  discussed  above and (ii) the decreases
      in volumes of oil and gas sold  during the six months  ended June 30, 1998
      as compared to the six months ended June 30, 1997.  As a percentage of oil
      and gas sales,  these expenses increased to 28.7% for the six months ended
      June 30,  1998 from 25.3% for the six months  ended  June 30,  1997.  This
      percentage  increase  was  primarily  due to the  decreases in the average
      prices of oil and gas sold  during the six months  ended June 30,  1998 as
      compared to the six months ended June 30, 1997.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      decreased  $86,865  (21.7%)  for the six  months  ended  June 30,  1998 as
      compared to the six months ended June 30,  1997.  This  decrease  resulted
      primarily from (i) the decreases in volumes of oil and gas sold during the
      six months  ended June 30, 1998 as  compared to the six months  ended June
      30, 1997 and (ii) upward  revisions  in the  estimates  of  remaining  gas
      reserves at December 31, 1997. As a percentage of oil and gas sales,  this
      expense  increased  to 14.9% for the six months  ended June 30,  1998 from
      12.4% for the six months ended June 30, 1997. This percentage increase was
      primarily due to the  decreases in the average  prices of oil and gas sold
      during the six months  ended June 30,  1998 as  compared to the six months
      ended June 30, 1997.

      The I-E  Partnership  recognized  a non-cash  charge  against  earnings of
      $291,690  during  the six  months  ended June 30,  1997.  Of this  amount,
      $59,728 was related to the decline in oil and gas prices used to determine
      the  recoverability  of proved oil and gas  reserves at March 31, 1997 and
      $231,962  was related to the writing  off of  unproved  properties.  These
      unproved  properties  were  written  off  based on the  General  Partner's
      determination that it was unlikely that such properties would be developed
      due to the low oil and gas prices  received  over the prior  several years
      and provisions in the I-E Partnership's  partnership agreement which limit
      the  level  of  permissible  drilling  activity.  No  similar  charge  was
      necessary during the six months ended June 30, 1998.

      General and  administrative  expenses  decreased $9,724 (3.4%) for the six
      months  ended June 30, 1998 as  compared to the six months  ended June 30,
      1997. As a percentage of oil and gas sales,  these  expenses  increased to
      13.0% for the six months ended June 30, 1998 from 8.8% for the six months

      ended June 30, 1997.  This  percentage  increase was  primarily due to the
      decrease in oil and gas sales discussed  above.  The Limited Partners have
      received cash distributions  through June 30, 1998 totaling $51,797,552 or
      123.80% of Limited Partners' capital contributions.

      As shown in the table above,  total oil and gas sales  decreased  $207,890
      (39.3%) for the three  months ended June 30, 1998 as compared to the three
      months ended June 30, 1997. Of this  decrease,  approximately  $26,000 and
      $92,000, respectively, were related to decreases in volumes of oil and gas
      sold and approximately $54,000 and $36,000, respectively,  were related to
      decreases  in the average  prices of oil and gas sold.  Volumes of oil and
      gas sold  decreased  1,433 barrels and 38,202 Mcf,  respectively,  for the
      three  months  ended June 30, 1998 as compared to the three  months  ended
      June 30, 1997. The decrease in volumes of oil sold resulted primarily from
      (i) normal  declines  in  production  due to  diminishing  reserves on two
      significant wells during the three months ended June 30, 1998 and (ii) the
      sale of one  significant  well during 1997. The decrease in volumes of gas
      sold resulted primarily from (i) a negative prior period volume adjustment
      by a purchaser on one significant  well during the three months ended June
      30, 1998 and (ii) the sale of several  wells  during the six months  ended
      June 30, 1998.  Average oil and gas prices  decreased to $11.74 per barrel
      and $2.07 per Mcf, respectively,  for the three months ended June 30, 1998
      from  $18.21  per barrel  and $2.41 per Mcf,  respectively,  for the three
      months ended June 30, 1997.

      As discussed in Liquidity and Capital Resources above, the I-F Partnership
      sold certain oil and gas properties during the three months ended June 30,
      1998 and recognized a $45,507 gain on such sales. Similar sales during the
      three  months  ended  June  30,  1997  resulted  in  the  I-F  Partnership
      recognizing similar gains totaling $46,356.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes)  decreased  $64,375  (31.6%) for the three months ended
      June 30, 1998 as compared to the three months  ended June 30,  1997.  This
      decrease  resulted  primarily from (i) the decreases in volumes of oil and
      gas sold during the three  months  ended March 31, 1998 as compared to the
      three months ended March 31, 1997 and (ii) a decrease in production  taxes
      associated  with the decrease in oil and gas sales  discussed  above. As a
      percentage of oil and gas sales, these expenses increased to 43.5% for the
      three  months  ended June 30, 1998 from 38.6% for the three  months  ended
      June 30, 1997. This percentage increase was primarily due to the decreases
      in the average  prices of oil and gas sold during the three  months  ended
      June 30, 1998 as compared to the three months ended June 30, 1997.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      decreased  $15,822  (25.0%)  for the three  months  ended June 30, 1998 as
      compared to the three months ended June 30, 1997.  This decrease  resulted
      primarily  from the  decreases  in volumes of oil and gas sold  during the
      three  months  ended June 30, 1998 as compared to the three  months  ended
      June  30,  1997.  As a  percentage  of oil and  gas  sales,  this  expense
      increased to 14.8% for the three months ended June 30, 1998 from 12.0% for
      the three  months  ended  June 30,  1997.  This  percentage  increase  was
      primarily due to the  decreases in the average  prices of oil and gas sold
      during the three  months  ended  June 30,  1998 as  compared  to the three
      months ended June 30, 1997.

      General and administrative expenses decreased $6,145 (12.7%) for the three
      months  ended June 30, 1998 as compared to the three months ended June 30,
      1997. This decrease was primarily due to a decrease in  professional  fees
      for the three  months  ended June 30, 1998 as compared to the three months
      ended June 30, 1997. As a percentage of oil and gas sales,  these expenses
      increased  to 13.2% for the three months ended June 30, 1998 from 9.2% for
      the three  months  ended  June 30,  1997.  This  percentage  increase  was
      primarily due to the decrease in oil and gas sales discussed above.

      SIX MONTHS  ENDED JUNE 30, 1998 AS  COMPARED TO THE SIX MONTHS  ENDED JUNE

                                                  -------------------------
                                                    1998            1997
                                                  --------       ----------
      Oil and gas sales                           $686,935       $1,128,873
      Oil and gas production expenses             $260,496       $  372,243
      Barrels produced                              16,194           19,522
      Mcf produced                                 220,708          291,400
      Average price/Bbl                           $  13.32       $    20.65
      Average price/Mcf                           $   2.14       $     2.49

      As shown in the table above,  total oil and gas sales  decreased  $441,938
      (39.1%)  for the six months  ended June 30,  1998 as  compared  to the six
      months ended June 30, 1997. Of this  decrease,  approximately  $69,000 and
      $176,000,  respectively,  were  related to decreases in volumes of oil and
      gas  sold and  approximately  $119,000  and  $78,000,  respectively,  were
      related to decreases in the average prices of oil and gas sold. Volumes of
      oil and gas sold decreased 3,328 barrels and 70,692 Mcf, respectively, for
      the six months  ended June 30, 1998 as  compared  to the six months  ended
      June 30, 1997. The decrease in volumes of oil sold resulted primarily from
      (i) normal  declines in  production  on several  significant  wells due to
      diminishing  reserves  during the six months  ended June 30, 1998 and (ii)
      the sale of one  significant  well in 1997. The decrease in volumes of gas
      sold resulted  primarily from (i) negative prior period volume adjustments
      on one  significant  well made by a purchaser  during the six months ended
      June 30, 1998 and (ii)  positive  prior period volume  adjustments  on two
      significant wells made by a purchaser during the six months ended June 30,
      1997.  Average oil and gas prices decreased to $13.32 per barrel and $2.14
      per Mcf, respectively,  for the six months ended June 30, 1998 from $20.65
      per barrel and $2.49 per Mcf, respectively,  for the six months ended June
      30, 1997.

      As discussed in Liquidity and Capital Resources above, the I-F Partnership
      sold certain oil and gas  properties  during the six months ended June 30,
      1998 and  recognized a $333,266  gain on such sales.  Similar sales during
      the three  months  ended June 30,  1997  resulted  in the I-F  Partnership
      recognizing similar gains totaling $46,356.




                                       45





      Oil and gas production  expenses  (including lease operating  expenses and
      production taxes) decreased $111,747 (30.0%) for the six months ended June
      30, 1998 as compared to the six months ended June 30, 1997.  This decrease
      resulted  primarily  from (i) the decreases in volumes of oil and gas sold
      during the six months  ended June 30,  1998 as  compared to the six months
      ended June 30, 1997 and (ii) a decrease  in  production  taxes  associated
      with the decrease in oil and gas sales discussed above. As a percentage of
      oil and gas sales,  these  expenses  increased to 37.9% for the six months
      ended June 30,  1998 from 33.0% for the six  months  ended June 30,  1997.
      This percentage increase was primarily due to the decreases in the average
      prices of oil and gas sold  during the six months  ended June 30,  1998 as
      compared to the six months ended June 30, 1997.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      decreased  $30,754  (24.3%)  for the six  months  ended  June 30,  1998 as
      compared to the six months ended June 30,  1997.  This  decrease  resulted
      primarily from the decreases in volumes of oil and gas sold during the six
      months  ended June 30, 1998 as  compared to the six months  ended June 30,
      1997.  As a percentage  of oil and gas sales,  this  expense  increased to
      14.0% for the six months ended June 30, 1998 from 11.2% for the six months
      ended June 30, 1997.  This  percentage  increase was  primarily due to the
      decreases in the average  prices of oil and gas sold during the six months
      ended June 30, 1998 as compared to the six months ended June 30, 1997.

      The I-F  Partnership  recognized  a non-cash  charge  against  earnings of
      $114,631  during  the six  months  ended June 30,  1997.  Of this  amount,
      $20,908 was related to the decline in oil and gas prices used to determine
      the  recoverability  of proved oil and gas  reserves at March 31, 1997 and
      $93,723  was related to the  writing  off of  unproved  properties.  These
      unproved  properties  were  written  off  based on the  General  Partner's
      determination that it was unlikely that such properties would be developed
      due to the low oil and gas prices  received  over the prior  several years
      and provisions in the I-F Partnership's  partnership agreement which limit
      the  level  of  permissible  drilling  activity.  No  similar  charge  was
      necessary during the six months ended June 30, 1998.

      General and  administrative  expenses  decreased $3,383 (3.5%) for the six
      months  ended June 30, 1998 as  compared to the six months  ended June 30,
      1997. As a percentage of oil and gas sales,  these  expenses  increased to
      13.7% for the six months ended June 30, 1998 from 8.6% for the six months



                                       46




      ended June 30, 1997. This  percentage  increase was primarily due to the
      decrease in oil and gas sales discussed above.

      The Limited  Partners have received  cash  distributions  through June 30,
      1998  totaling   $17,512,664  or  122.29%  of  Limited  Partners'  capital
      contributions.
