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

      The combined  balance sheets as of June 30, 2005,  combined  statements of
      operations  for the three and six months ended June 30, 2005 and 2004, and
      combined  statements  of cash flows for the six months ended June 30, 2005
      and 2004 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, 2005, the combined results of operations for the three and six
      months ended June 30, 2005 and 2004,  and the combined  cash flows for the
      six months ended June 30, 2005 and 2004.

      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, 2004. The
      results  of  operations  for  the  period  ended  June  30,  2005  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.




                                      -22-


      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.

      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 and estimated salvage value of the equipment.

      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.


      ASSET RETIREMENT OBLIGATIONS
      ----------------------------

      The Partnerships' wells must be properly plugged and abandoned after their
      oil and gas reserves are exhausted.  The Partnerships  follow FAS No. 143,
      "Accounting for Asset Retirement Obligations" in accounting for the future
      expenditures  that will be necessary to plug and abandon these wells.  FAS
      No. 143 requires the estimated plugging and abandonment  obligations to be
      recognized in the period in which they are incurred (i.e. when the well is
      drilled or acquired)  if a  reasonable  estimate of fair value can be made
      and to be capitalized as part of the carrying amount of the well.





                                      -23-


      The asset  retirement  obligation will be adjusted upwards each quarter in
      order to recognize accretion of the time-related  discount factor. For the
      six  months  ended  June  30,  2005,  the  P-1,  P-3,  P-4,  P-5,  and P-6
      Partnerships recognized  approximately $2,000, $3,000, $1,000, $2,000, and
      $5,000 of an increase in  depletion  of Net Profits  Interests,  which was
      comprised of accretion of the asset retirement obligation and depletion of
      the increase in Net Profits Interests.

      The components of the change in asset retirement obligations for the three
      and six months ended June 30, 2005 and 2004 are as shown below.

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  underlying  Working
      Interests.   The  net  proceeds  from  the  oil  and  gas  operations  are
      distributed to the Limited Partners


                                      -29-


      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-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, 2005 and the net
      revenue generated from future operations will provide  sufficient  working
      capital to meet current and future obligations.

      Occasional  expenditures  by the owners of the Working  Interests  for new
      wells or well recompletions or workovers, however, may reduce or eliminate
      cash available for a particular quarterly cash distribution.

      The  Partnerships'  termination  date under the partnership  agreements is
      December  31,  2005.  The  General  Partner  may  extend  the terms of the
      Partnerships  for up to  five  two-year  extension  periods.  The  General
      Partner  has not yet  determined  whether it will  extend the terms of any
      Partnership.



                                      -30-


CRITICAL ACCOUNTING POLICIES
- ----------------------------

      The  Partnerships  follow the successful  efforts method of accounting for
      their Net Profits  Interests.  Under the successful  efforts  method,  the
      Partnerships  capitalize all acquisition  costs.  Such  acquisition  costs
      include  costs  incurred by the  Partnerships  or the  General  Partner to
      acquire a Net Profits  Interest,  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  net
      acquisition  cost to the  Partnerships  of the Net  Profits  Interests  in
      properties  acquired  by the  General  Partner  consists  of the  cost  of
      acquiring the underlying  properties  adjusted for the net cash results of
      operations,  including any interest  incurred to finance the  acquisition,
      for the period of time the properties are held by the General Partner.

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

      The  Partnerships  evaluate the  recoverability  of the carrying  costs of
      their Net Profits  Interests in proved oil and gas properties for each oil
      and gas field (rather than  separately for each well).  If the unamortized
      costs of a Net  Profits  Interest  within  a field  exceeds  the  expected
      undiscounted future cash flows from such Net Profits Interest, the cost of
      the  Net  Profits  Interest  is  written  down  to fair  value,  which  is
      determined  by using the estimated  discounted  future cash flows from the
      Net Profits Interest.


      Accounts Receivable (Accounts Payable) - Net Profits

      Revenues from a Net Profits Interest consist of a share of the oil and gas
      sales  of the  property,  less  operating  and  production  expenses.  The
      partnerships  accrue for oil and gas revenues  less  expenses from the Net
      Profits  Interests.  Sales of gas applicable to the Net Profits  Interests
      are  recorded  as revenue  when the gas is metered  and title  transferred
      pursuant  to the gas sales  contracts.  During  such times as sales of gas
      exceed a  Partnership's  pro rata share of  estimated  total gas  reserves
      attributable  to the  underlying  property,  such  excess is recorded as a
      liability. The rates per Mcf used to calculate this liability are based on
      the average gas price for which the  Partnerships  are currently  settling
      this  liability.  This  liability  is recorded as a reduction  of accounts
      receivable.


                                      -31-


      Also included in accounts  receivable  (payable) - Net Profits are amounts
      which  represent  costs  deferred or accrued  for Net Profits  relating to
      lease operating expenses incurred in connection with the net underproduced
      or overproduced gas imbalance positions.  The rate used in calculating the
      deferred  charge or accrued  liability  is the annual  average  production
      costs per Mcf.  Also  included  in  accounts  receivable  (payable)  - Net
      Profits is the asset retirement obligation.


ASSET RETIREMENT OBLIGATIONS
- ----------------------------

      The Partnerships' wells must be properly plugged and abandoned after their
      oil and gas reserves are exhausted.  The Partnerships  follow FAS No. 143,
      "Accounting for Asset Retirement Obligations" in accounting for the future
      expenditures  that will be necessary to plug and abandon these wells.  FAS
      No. 143 requires the estimated plugging and abandonment  obligations to be
      recognized in the period in which they are incurred (i.e. when the well is
      drilled or acquired)  if a  reasonable  estimate of fair value can be made
      and to be capitalized as part of the carrying amount of the well.


NEW ACCOUNTING PRONOUNCEMENTS
- -----------------------------

      The  Partnerships  are  not  aware  of  any  recently  issued   accounting
      pronouncements  that  would  have an  impact on the  Partnerships'  future
      results of operations and financial position.


PROVED RESERVES AND NET PRESENT VALUE
- -------------------------------------

      The process of  estimating  oil and gas  reserves  is  complex,  requiring
      significant   subjective   decisions  in  the   evaluation   of  available
      geological,  engineering,  and economic data for each reservoir.  The data
      for a given reservoir may change  substantially  over time as a result of,
      among other things,  additional development activity,  production history,
      and  viability  of   production   under   varying   economic   conditions;
      consequently,  it  is  reasonably  possible  that  material  revisions  to
      existing  reserve  estimates  may  occur  in the  future.  Although  every
      reasonable  effort has been made to ensure  that these  reserve  estimates
      represent the most accurate assessment  possible,  the significance of the
      subjective  decisions required and variances in available data for various
      reservoirs  make  these  estimates   generally  less  precise  than  other
      estimates presented in connection with financial statement disclosures.


                                      -32-


      The  following  tables   summarize   changes  in  net  quantities  of  the
      Partnerships'  proved  reserves,  all of which are  located  in the United
      States, for the periods  indicated.  The proved reserves were estimated by
      petroleum  engineers  employed by affiliates of the Partnerships,  and are
      annually reviewed by an independent  engineering  firm.  "Proved reserves"
      refers to those  estimated  quantities  of crude oil, gas, and gas liquids
      which   geological  and  engineering   data  demonstrate  with  reasonable
      certainty  to be  recoverable  in  future  years  from  known  oil and gas
      reservoirs under existing economic and operating conditions. The following
      information includes certain gas balancing adjustments which cause the gas
      volume to differ from the reserve reports prepared by the General Partner.

      The  net  present   value  of  the   Partnerships'   reserves  may  change
      dramatically  as oil and gas prices  change or as  volumes  change for the
      reasons  described above.  Net present value  represents  estimated future
      gross cash flow from the  production and sale of proved  reserves,  net of
      estimated oil and gas production  costs  (including  production  taxes, ad
      valorem taxes, and operating  expenses) and estimated  future  development
      costs, discounted at 10% per annum.

      The  following  table  indicates  the  estimated  net present value of the
      Partnerships'  proved  reserves as of June 30, 2005,  March 31, 2005,  and
      December 31, 2004.  Net present value  attributable  to the  Partnerships'
      proved reserves was calculated on the basis of current costs and prices as
      of the date of  estimation.  Such  prices  were not  escalated  except  in
      certain   circumstances   where   escalations   were  fixed  and   readily
      determinable in accordance with applicable contract provisions.  The table
      also indicates the gas prices in effect on the dates  corresponding to the
      reserve  valuations.  Changes  in the oil and gas prices  have  caused the
      estimates of remaining  economically  recoverable reserves, as well as the
      values  placed  on  said  reserves  to  fluctuate.   The  prices  used  in
      calculating the net present value attributable to the Partnerships' proved
      reserves  do not  necessarily  reflect  market  prices  for  oil  and  gas
      production subsequent to June 30, 2005. There can be no assurance that the
      prices  used in  calculating  the net present  value of the  Partnerships'
      proved  reserves  at June 30,  2005 will  actually  be  realized  for such
      production.

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

      GENERAL DISCUSSION

      The following  general  discussion  should be read in conjunction with the
      analysis of results of operations provided below.

      The primary source of liquidity and Partnership cash  distributions  comes
      from the net revenues generated from the sale of oil and gas produced from
      the  Partnerships'  oil and gas  properties.  The level of net revenues is
      highly  dependent  upon the total volumes of oil and natural gas sold. Oil
      and gas  reserves  are  depleting  assets and will  experience  production
      declines over time, thereby likely resulting in reduced net revenues.  The
      level of net revenues is also highly  dependent  upon the prices  received
      for oil and gas sales,  which prices have  historically been very volatile
      and may continue to be so.

      Additionally,  lower oil and  natural  gas prices may reduce the amount of
      oil and gas that is  economic  to produce  and  reduce  the  Partnerships'
      revenues and cash flow.  Various factors beyond the Partnerships'  control
      will affect prices for oil and natural gas, such as:

            *     Worldwide and domestic supplies of oil and natural gas;
            *     The ability of the members of the  Organization of Petroleum
                  Exporting  Countries  ("OPEC") to agree to and  maintain oil
                  prices and production quotas;
            *     Political  instability  or armed  conflict in  oil-producing
                  regions or around major shipping areas;
            *     The level of consumer demand and overall economic activity;
            *     The competitiveness  of alternative fuels;
            *     Weather  conditions;
            *     The availability  of pipelines  for  transportation;  and
            *     Domestic and foreign government regulations and taxes.

      It is not  possible to predict the future  direction of oil or natural gas
      prices or whether the above discussed trends will remain. Operating costs,
      including General and Administrative  Expenses,  may not decline over time
      or may experience  only a gradual  decline,  thus adversely  affecting net
      revenues as either  production or oil and natural gas prices  decline.  In
      any  particular  period,  net  revenues may also be affected by either the
      receipt of proceeds  from  property  sales or the  incursion of additional
      costs as a result of well workovers, recompletions, new well drilling, and
      other events.


                                      -37-


      In addition to pricing, the level of net revenues is also highly dependent
      upon the total  volumes of oil and natural gas sold.  Oil and gas reserves
      are depleting  assets and will experience  production  declines over time,
      thereby  likely  resulting in reduced net  revenues.  Despite this general
      trend of declining  production,  several  factors can cause the volumes of
      oil and gas sold to increase or  decrease at an even  greater  rate over a
      given  period.  These  factors  include,  but  are  not  limited  to,  (i)
      geophysical  conditions  which  cause an  acceleration  of the  decline in
      production,  (ii) the  shutting in of wells (or the opening of  previously
      shut-in wells) due to low oil and gas prices (or high oil and gas prices),
      mechanical   difficulties,   loss  of  a  market  or  transportation,   or
      performance of workovers,  recompletions, or other operations in the well,
      (iii) prior period volume  adjustments  (either positive or negative) made
      by the  purchasers  of  the  production,  (iv)  ownership  adjustments  in
      accordance  with  agreements  governing  the operation or ownership of the
      well (such as  adjustments  that occur at payout),  and (v)  completion of
      enhanced recovery projects which increase production for the well. Many of
      these  factors  are very  significant  as related  to a single  well or as
      related  to many wells over a short  period of time.  However,  due to the
      large  number  of  wells  owned by the  Partnerships,  these  factors  are
      generally  not material as compared to the normal  declines in  production
      experienced on all remaining wells.

      As shown in the table above,  total Net Profits  increased $51,376 (13.2%)
      for the three  months  ended June 30, 2005 as compared to the three months
      ended June 30,  2004.  Of this  increase,  approximately  (i)  $63,000 and
      $8,000,  respectively,  were related to increases in the average prices of
      oil and gas sold and (ii) $7,000 and $3,000, respectively, were related to
      increases in volumes of oil and gas sold.  These  increases were partially
      offset by a decrease of  approximately  $30,000  related to an increase in
      production expenses. Volumes of oil and gas sold increased 211 barrels and
      623 Mcf,  respectively,  for the  three  months  ended  June  30,  2005 as
      compared to the three months ended June 30, 2004. The increases in volumes
      of oil and gas sold


                                      -38-


      were primarily due to positive prior period volume adjustments made by the
      operators  on several  wells  during the three months ended June 30, 2005.
      These  increases were  partially  offset by a negative prior period volume
      adjustment  made by the  operator on another  significant  well during the
      three months ended June 30, 2005. The increase in production  expenses was
      primarily  due to (i) workover  expenses  incurred on several wells during
      the three months ended June 30, 2005, (ii) an increase in production taxes
      associated  with the increase in oil and gas sales,  and (iii) an increase
      in salt water disposal  expenses  incurred on one significant  well during
      the three months ended June 30, 2005 as compared to the three months ended
      June 30, 2004.

      Depletion of Net Profits Interests  increased $4,574 (34.6%) for the three
      months  ended June 30, 2005 as compared to the three months ended June 30,
      2004.  This increase was  primarily  due to (i) downward  revisions in the
      estimates of remaining gas reserves since June 30, 2004,  (ii) an increase
      in  depletable  Net Profits  Interests  during 2005  primarily  due to the
      drilling of one developmental  well, and (iii) the increases in volumes of
      oil and gas sold. As a percentage of Net Profits,  this expense  increased
      to 4.0% for the three  months  ended June 30, 2005 from 3.4% for the three
      months ended June 30, 2004. This percentage  increase was primarily due to
      the dollar increase in depletion of Net Profits Interests.

      General and administrative expenses decreased $14,371 for the three months
      ended June 30, 2005 as compared to the three  months  ended June 30, 2004.
      As a percentage of Net Profits,  these expenses  decreased to 7.0% for the
      three  months  ended June 30, 2005 from 11.6% for the three  months  ended
      June 30, 2004.  This  percentage  decrease was primarily due to the dollar
      decrease in general and administrative expenses.

      As shown in the table above,  total Net Profits increased $182,446 (22.6%)
      for the six months ended June 30, 2005 as compared to the six months ended
      June 30, 2004.  Of this  increase,  approximately  $135,000 and  $124,000,
      respectively,  were related to increases in the average  prices of oil and
      gas sold. These increases were partially offset by


                                      -39-


      decreases of approximately (i) $16,000 and $46,000, respectively,  related
      to decreases in volumes of oil and gas sold and (ii) $15,000 related to an
      increase in production expenses. Volumes of oil and gas sold decreased 488
      barrels  and 9,935 Mcf,  respectively,  for the six months  ended June 30,
      2005 as compared to the six months ended June 30, 2004.

      The  decrease in volumes of oil sold was  primarily  due to (i) a negative
      prior period  volume  adjustment  made by the operator on one  significant
      well during the six months ended June 30, 2005, (ii) positive prior period
      volume  adjustments  made by the operators on several wells during the six
      months ended June 30, 2004, and (iii) normal declines in production. These
      decreases   were   partially   offset  by  positive  prior  period  volume
      adjustments  made by the  operators on several wells during the six months
      ended June 30, 2005. The decrease in volumes of gas sold was primarily due
      to (i) a negative prior period volume  adjustment  made by the operator on
      one  significant  well  during the six months  ended June 30,  2005,  (ii)
      normal  declines in  production,  and (iii) a positive prior period volume
      adjustment made by the operator on another significant well during the six
      months ended June 30,  2004.  These  decreases  were  partially  offset by
      positive prior period volume  adjustments made by the operators on several
      wells during the six months ended June 30, 2005.

      The increase in  production  expenses was primarily due to (i) an increase
      in  production  taxes  associated  with the increase in oil and gas sales,
      (ii)  workover  expenses  incurred on several  wells during the six months
      ended June 30, 2005, and (iii) an increase in salt water disposal expenses
      incurred on one significant well during the six months ended June 30, 2005
      as compared to the six months ended June 30, 2004.  These  increases  were
      partially  offset  by  the  receipt  of ad  valorem  tax  credits  on  one
      significant well during the six months ended June 30, 2005.

      Depletion of Net Profits  Interests  increased  $1,304  (4.1%) for the six
      months  ended June 30, 2005 as  compared to the six months  ended June 30,
      2004. This increase was primarily due to (i) an increase in depletable Net
      Profits  Interests  during  2005  primarily  due  to the  drilling  of two
      developmental  wells  and (ii)  downward  revisions  in the  estimates  of
      remaining gas reserves since June 30, 2004. These increases were partially
      offset by the decreases in volumes of oil and gas sold. As a percentage of
      Net Profits,  this expense decreased to 3.4% for the six months ended June
      30, 2005 from 4.0% for the six months ended June 30, 2004. This percentage
      decrease was primarily  due to the increases in the average  prices of oil
      and gas sold.



                                      -40-




      General and  administrative  expenses  increased $1,010 for the six months
      ended June 30, 2005 as compared to the six months ended June 30, 2004.  As
      a percentage of Net Profits,  these expenses decreased to 8.4% for the six
      months  ended June 30,  2005 from 10.1% for the six months  ended June 30,
      2004.  This  percentage  decrease was primarily due to the increase in Net
      Profits.

      Cumulative cash  distributions  to the Limited  Partners  through June 30,

      for the three  months  ended June 30, 2005 as compared to the three months
      ended June 30,  2004.  Of this  increase,  approximately  (i)  $79,000 and
      $30,000, respectively,  were related to increases in the average prices of
      oil and gas sold and (ii) $8,000 and $1,000, respectively, were related to
      the  increases  in  volumes  of oil and gas  sold.  These  increases  were
      partially  offset by a decrease  of  approximately  $42,000  related to an
      increase in production expenses. Volumes of oil and gas sold increased 234
      barrels and 284 Mcf,  respectively,  for the three  months  ended June 30,
      2005 as compared to the three months ended June 30, 2004. The increases in
      volumes of oil and gas sold were  primarily  due to positive  prior period
      volume adjustments made by the operators on several wells during the three
      months ended June 30, 2005.  These  increases were  partially  offset by a
      negative  prior period volume  adjustment  made by the operator on another
      significant well during the three months ended June 30, 2005. The increase
      in production expenses was primarily due to (i) workover expenses incurred
      on several  wells during the three  months  ended June 30,  2005,  (ii) an
      increase in production  taxes  associated with the increase in oil and gas
      sales, and (iii) an increase in salt water disposal  expenses  incurred on
      one  significant  well  during the three  months  ended  June 30,  2005 as
      compared to the three months ended June 30, 2004.


                                      -41-


      Depletion of Net Profits Interests  increased $4,114 (21.4%) for the three
      months  ended June 30, 2005 as compared to the three months ended June 30,
      2004.  This increase was primarily due to (i) one  significant  well being
      fully depleted during the three months ended June 30, 2005 due to the lack
      of  remaining  reserves,  (ii)  downward  revisions  in the  estimates  of
      remaining  gas  reserves  since June 30,  2004,  and (iii) an  increase in
      depletable Net Profits Interests during 2005 primarily due to the drilling
      of one  developmental  well. As a percentage of Net Profits,  this expense
      increased  to 3.7% for the three  months ended June 30, 2005 from 3.4% for
      the three months ended June 30, 2004.

      General and administrative expenses decreased $14,689 for the three months

      As a percentage of Net Profits,  these expenses  decreased to 7.5% for the
      three  months  ended June 30, 2005 from 11.1% for the three  months  ended
      June 30, 2004.  This  percentage  decrease was primarily due to the dollar

      As shown in the table above,  total Net Profits increased $242,268 (20.5%)
      for the six months ended June 30, 2005 as compared to the six months ended
      June 30, 2004.  Of this  increase,  approximately  $175,000 and  $188,000,
      respectively,  were related to increases in the average  prices of oil and
      gas  sold.   These  increases  were  partially   offset  by  decreases  of
      approximately (i) $20,000 and $85,000, respectively,  related to decreases
      in volumes of oil and gas sold and (ii) $15,000  related to an increase in
      production expenses. Volumes of oil and gas sold decreased 616 barrels and
      17,597  Mcf,  respectively,  for the six  months  ended  June 30,  2005 as
      compared to the six months ended June 30, 2004.

      The  decrease in volumes of oil sold was  primarily  due to (i) a negative
      prior period  volume  adjustment  made by the operator on one  significant
      well during the six months ended June 30, 2005, (ii) positive prior period
      volume  adjustments  made by the operators on several wells during the six
      months ended June 30, 2004, and (iii) normal declines in production. These
      decreases   were   partially   offset  by  positive  prior  period  volume
      adjustments made by the


                                      -42-


      operators  on several  other  wells  during the six months  ended June 30,
      2005.  The  decrease  in  volumes of gas sold was  primarily  due to (i) a
      negative  prior  period  volume  adjustment  made by the  operator  on one
      significant  well during the six months ended June 30,  2005,  (ii) normal
      declines  in  production,   and  (iii)  a  positive  prior  period  volume
      adjustment made by the operator on another significant well during the six
      months ended June 30,  2004.  These  decreases  were  partially  offset by
      positive prior period volume  adjustments made by the operators on several
      other wells during the six months ended June 30, 2005.

      The increase in  production  expenses was primarily due to (i) an increase
      in  production  taxes  associated  with the increase in oil and gas sales,
      (ii)  workover  expenses  incurred on several  wells during the six months
      ended June 30, 2005, and (iii) an increase in salt water disposal expenses
      incurred on one significant well during the six months ended June 30, 2005
      as compared to the six months ended June 30, 2004.  These  increases  were
      partially  offset  by  the  receipt  of ad  valorem  tax  credits  on  one
      significant well during the six months ended June 30, 2005.

      Depletion of Net Profits  Interests  increased  $2,946  (6.1%) for the six
      months  ended June 30, 2005 as  compared to the six months  ended June 30,
      2004. This increase was primarily due to (i) an increase in depletable Net
      Profits  Interests  during  2005  primarily  due  to the  drilling  of two
      developmental wells, (ii) downward revisions in the estimates of remaining
      gas reserves  since June 30, 2004,  and (iii) one  significant  well being
      fully  depleted  during the six months ended June 30, 2005 due to the lack
      of  remaining  reserves.  These  increases  were  partially  offset by the
      decreases in volumes of oil and gas sold.  As a percentage of Net Profits,
      this expense decreased to 3.6% for the six months ended June 30, 2005 from
      4.1% for the six months ended June 30, 2004. This percentage  decrease was
      primarily due to the increases in the average prices of oil and gas sold.

      General and administrative  expenses remained  relatively constant for the
      six months ended June 30, 2005 and 2004.  As a percentage  of Net Profits,
      these  expenses  decreased  to 8.2% for the six months ended June 30, 2005
      from 9.8% for the six months ended June 30, 2004. This percentage decrease
      was primarily due to the increase in Net Profits.

      Cumulative cash  distributions  to the Limited  Partners  through June 30,

      the three months ended June 30, 2005 as compared to the three months ended
      June 30,  2004.  Of this  increase,  approximately  $59,000  and  $32,000,
      respectively,  were related to increases in the average  prices of oil and
      gas  sold.   These  increases  were  partially   offset  by  decreases  of
      approximately (i) $33,000 and $34,000, respectively,  related to decreases
      in volumes of oil and gas sold and (ii) $17,000  related to an increase in
      production expenses. Volumes of oil and gas sold decreased 911 barrels and
      5,753 Mcf,  respectively,  for the three  months  ended  June 30,  2005 as
      compared to the three months ended June 30, 2004.  The decrease in volumes
      of oil sold was  primarily due to (i) normal  declines in  production  and
      (ii) the  shutting-in of several wells during early 2005 due to mechanical
      problems.  As of the date of this Quarterly Report, the shut-in wells have
      returned to production at a lower rate than  previously  experienced.  The
      decrease in volumes of gas sold was  primarily  due to normal  declines in
      production.  The increase in production  expenses was primarily due to (i)
      workover  expenses incurred on several wells during the three months ended
      June 30, 2005, (ii) compression  expenses  incurred on several other wells
      during the three  months  ended June 30,  2005,  and (iii) an  increase in
      production taxes associated with the increase in oil and gas sales.

      Depletion of Net Profits Interests decreased $13,995 (56.0%) for the three
      months  ended June 30, 2005 as compared to the three months ended June 30,
      2004.  This  decrease  was  primarily  due to (i) upward  revisions in the
      estimates of remaining oil and gas reserves on one significant  well since
      June 30, 2004,  (ii) the  abandonment of another  significant  well during
      2004  following  an  unsuccessful  recompletion  attempt,  and  (iii)  the
      decreases in volumes of oil and gas sold.  As a percentage of Net Profits,
      this  expense  decreased  to 2.5% for the three months ended June 30, 2005
      from  5.7% for the three  months  ended  June 30,  2004.  This  percentage
      decrease  was  primarily  due to the dollar  decrease in  depletion of Net
      Profits Interests.

      three  months  ended June 30, 2005 from 11.5% for the three  months  ended
      June 30, 2004.  This  percentage  decrease was primarily due to the dollar
      decrease in general and administrative expenses.

      As shown in the table above,  total Net Profits  decreased  $47,726 (5.7%)
      for the six months ended June 30, 2005 as compared to the six months ended
      June 30, 2004. Of this  decrease,  approximately  (i) $65,000 and $91,000,
      respectively, were related to decreases in volumes of oil and gas sold and
      (ii)  $78,000 was related to an increase  in  production  expenses.  These
      decreases were partially offset by increases of approximately $104,000 and
      $82,000,  respectively,  related to increases in the average prices of oil
      and gas sold.  Volumes of oil and gas sold  decreased  1,829  barrels  and
      16,280  Mcf,  respectively,  for the six  months  ended  June 30,  2005 as
      compared to the six months ended June 30, 2004. The decrease in volumes of
      oil sold was primarily due to (i) the shutting-in of one significant  well
      during  late  2004 and early  2005 due to  mechanical  problems,  (ii) the
      shutting-in  of several  other wells during  early 2005 due to  mechanical
      problems, and (iii) normal declines in production.  As of the date of this
      Quarterly Report, the shut-in wells have returned to production at a lower
      rate than previously experienced.  The decrease in volumes of gas sold was
      primarily due to (i) a positive prior period volume adjustment made by the
      operator on one significant well during the six months ended June 30, 2004
      and (ii)  normal  declines  in  production.  The  increase  in  production
      expenses was  primarily due to (i) workover  expenses  incurred on several
      wells  during the six months ended June 30,  2005,  (ii) a positive  prior
      period  production tax adjustment  made by the operator on one significant
      well during the six months ended June 30,  2005,  and (iii) an increase in
      salt water  disposal  expenses  incurred on several other wells during the
      six months  ended June 30, 2005 as  compared to the six months  ended June
      30, 2004.

      Depletion of Net Profits  Interests  decreased $36,447 (61.6%) for the six
      months  ended June 30, 2005 as  compared to the six months  ended June 30,
      2004.  This  decrease  was  primarily  due to (i) the  abandonment  of one
      significant  well  during  2004  following  an  unsuccessful  recompletion
      attempt,  (ii) the  decreases  in volumes  of oil and gas sold,  and (iii)
      upward revisions in the estimates of remaining oil and gas reserves on one
      significant well since June 30, 2004. As a percentage of Net Profits, this
      expense decreased to 2.9% for the six months ended June 30, 2005 from 7.1%
      for the six months  ended June 30,  2004.  This  percentage  decrease  was
      primarily  due  to  the  dollar  decrease  in  depletion  of  Net  Profits
      Interests.

      General and  administrative  expenses  increased $1,743 for the six months
      ended June 30, 2005 as compared to the six months ended June 30, 2004.  As

      As shown in the table above,  total Net Profits  increased $50,030 (13.7%)
      for the three  months  ended June 30, 2005 as compared to the three months
      ended June 30,  2004.  Of this  increase,  approximately  (i)  $89,000 was
      related to an increase in volumes of gas sold and (ii) $14,000 was related
      to an increase  in the average  price of oil sold.  These  increases  were
      partially  offset by decreases of  approximately  (i) $42,000 related to a
      decrease in the average  price of gas sold and (ii)  $12,000  related to a
      decrease  in  volumes  of oil  sold.  Volumes  of oil sold  decreased  330
      barrels,  while  volumes  of gas sold  increased  14,115 Mcf for the three
      months  ended June 30, 2005 as compared to the three months ended June 30,
      2004.


                                      -46-



      The  decrease  in  volumes  of oil sold was  primarily  due to (i)  normal
      declines in production and (ii) positive  prior period volume  adjustments
      made by the  operators  on two  significant  wells during the three months
      ended June 30, 2004. The increase in volumes of gas sold was primarily due
      to (i)  downward  revisions in the  estimates  of  remaining  gas reserves
      during  the three  months  ended  June 30,  2004 on one  significant  well
      resulting in the P-5  Partnership  becoming  over  produced  past ultimate
      reserves  thereby  increasing gas imbalance  payable,  (ii) the successful
      completion  of  several  new wells  during  mid and late  2004,  and (iii)
      positive prior period volume  adjustments made by the operators on several
      wells during the three months ended June 30, 2005.  These  increases  were
      partially offset by (i) a substantial decline in production during 2005 on
      one  significant  well following the workover of that well during mid 2004
      and (ii) normal  declines  in  production.  The well with the  substantial
      decline in  production  is not expected to return to its  previously  high
      levels of production.

      The  average  gas price  decreased  to $5.75 per Mcf for the three  months
      ended June 30, 2005 from $6.31 per Mcf for the three months ended June 30,
      2004. Due to a gas imbalance  situation on one significant  well discussed
      above,  gas  volumes  for that  well were  recorded  as a  liability  at a
      substantially  lower rate per Mcf than the average  price per Mcf received
      by the P-5  Partnership  during the three months ended June 30, 2004. This
      resulted in a higher average price per Mcf for the three months ended June
      30, 2004 than if the  liability  had not been  recorded.  No such material
      adjustments were recorded during the three months ended June 30, 2005.

      A decrease in production  expenses  primarily due to (i) workover expenses
      incurred on several  wells during the three months ended June 30, 2004 and
      (ii) a decrease  in repair and  maintenance  expenses  incurred on several
      other wells during the three months ended June 30, 2005 as compared to the
      three months ended June 30, 2004 was substantially  offset by (i) workover
      expenses  incurred on several wells during the three months ended June 30,
      2005 and (ii) an increase in production taxes associated with the increase
      in oil and gas sales.

      Depletion of Net Profits Interests decreased $13,981 (60.3%) for the three
      months  ended June 30, 2005 as compared to the three months ended June 30,
      2004. This decrease was primarily due to two significant wells being fully
      depleted  during the three  months  ended June 30, 2004 due to the lack of
      remaining reserves. As a percentage of Net Profits, this expense decreased
      to 2.2% for the three  months  ended June 30, 2005 from 6.4% for the three
      months ended June 30, 2004. This percentage  decrease was primarily due to
      the dollar decrease in depletion of Net Profits Interests.


                                      -47-



      General and administrative expenses decreased $14,423 for the three months

      As a percentage of Net Profits,  these expenses  decreased to 8.1% for the
      three  months  ended June 30, 2005 from 13.2% for the three  months  ended
      June 30, 2004.  This  percentage  decrease was primarily due to the dollar
      decrease in general and administrative expenses.

      As shown in the table above,  total Net Profits increased $111,899 (16.5%)
      for the six months ended June 30, 2005 as compared to the six months ended
      June 30, 2004. Of this  increase,  approximately  (i) $31,000 and $86,000,
      respectively,  were related to increases in the average  prices of oil and
      gas sold and (ii)  $22,000  was  related to an  increase in volumes of gas
      sold.  These increases were partially offset by decreases of approximately
      (i) $15,000  related to a decrease in volumes of oil sold and (ii) $12,000
      related  to an  increase  in  production  expenses.  Volumes  of oil  sold
      decreased 430 barrels,  while volumes of gas sold increased  3,968 Mcf for
      the six months  ended June 30, 2005 as  compared  to the six months  ended
      June 30, 2004.

      The  decrease  in volumes of oil sold was  primarily  due to (i)  positive
      prior period volume  adjustments  made by the operators on two significant
      wells during the six months  ended June 30, 2004 and (ii) normal  declines
      in  production.  The increase in volumes of gas sold was  primarily due to
      (i) downward  revisions in the estimates of remaining gas reserves  during
      the six months ended June 30, 2004 on one  significant  well  resulting in
      the P-5 Partnership  becoming over produced past ultimate reserves thereby
      increasing  gas  imbalance  payable,  (ii) the  successful  completion  of
      several  new wells  during mid and late  2004,  and (iii)  positive  prior
      period  volume  adjustments  made by the  operators on several other wells
      during the six months ended June 30, 2005.  These increases were partially
      offset by (i) normal declines in production and (ii) a substantial decline
      in production  during 2005 on one significant  well following the workover
      of that well  during mid 2004.  The well with the  substantial  decline in
      production is not expected to return to its


                                      -48-


      previously  high levels of production.  The average gas price increased to
      $6.06 per Mcf for the six months  ended  June 30,  2005 from $5.44 per Mcf
      for the six months ended June 30, 2004.  Due to a gas imbalance  situation
      on one significant  well discussed  above,  gas volumes for that well were
      recorded as a  liability  at a  substantially  lower rate per Mcf than the
      average  price per Mcf  received  by the P-5  Partnership  during  the six
      months ended June 30, 2004.  This  resulted in a higher  average price per
      Mcf for the six months ended June 30, 2004 than if the  liability  had not
      been recorded.  No such material  adjustments were recorded during the six
      months ended June 30, 2005.

      The  increase in  production  expenses was  primarily  due to (i) workover
      expenses  incurred on several wells during the six months ended June,  30,
      2005, (ii) an increase in production taxes associated with the increase in
      oil and gas  sales,  and  (iii) an  increase  in  repair  and  maintenance
      expenses  incurred on two  significant  wells  during the six months ended
      June 30,  2005 as compared to the six months  ended June 30,  2004.  These
      increases were partially offset by workover  expenses  incurred on several
      other wells during the six months ended June 30, 2004.

      Depletion of Net Profits  Interests  decreased $14,360 (26.8%) for the six
      months  ended June 30, 2005 as  compared to the six months  ended June 30,
      2004. This decrease was primarily due to two significant wells being fully
      depleted  during  the six months  ended  June 30,  2004 due to the lack of
      remaining  reserves.  This decrease was partially offset by an increase in
      depletable Net Profits Interests during 2005 primarily due to the drilling
      of two developmental  wells. As a percentage of Net Profits,  this expense
      decreased to 5.0% for the six months ended June 30, 2005 from 7.9% for the
      six months ended June 30, 2004. This percentage decrease was primarily due
      to (i) the dollar decrease in depletion of Net Profits  Interests and (ii)
      the increases in the average prices of oil and gas sold.

      General and  administrative  expenses  increased $1,828 for the six months
      ended June 30, 2005 as compared to the six months ended June 30, 2004.  As
      a percentage of Net Profits, these expenses decreased to 11.2% for the six
      months  ended June 30,  2005 from 12.7% for the six months  ended June 30,
      2004.  This  percentage  decrease was primarily due to the increase in Net
      Profits.

      Cumulative cash  distributions  to the Limited  Partners  through June 30,
      2005  were   $13,666,759   or  115.38%  of   Limited   Partners'   capital

      Barrels produced                               2,830          2,502

      Average price/Bbl                           $  51.17       $  37.56
      Average price/Mcf                           $   6.10       $   5.70

      As shown in the table above,  total Net Profits increased $128,230 (23.7%)
      for the three  months  ended June 30, 2005 as compared to the three months
      ended June 30,  2004.  Of this  increase,  approximately  (i)  $39,000 and
      $45,000, respectively,  were related to increases in the average prices of
      oil and gas sold,  (ii)  $28,000  was related to an increase in volumes of
      gas sold,  and (iii)  $5,000  was  related  to a  decrease  in  production
      expenses. Volumes of oil and gas sold increased 328 barrels and 4,828 Mcf,
      respectively,  for the three months ended June 30, 2005 as compared to the
      three months ended June 30, 2004.

      The  increase  in volumes of gas sold was  primarily  due to (i)  downward
      revisions  in the  estimates of  remaining  gas reserves  during the three
      months ended June 30, 2004 on one  significant  well  resulting in the P-6
      Partnership   becoming  over  produced  past  ultimate   reserves  thereby
      increasing  gas  imbalance  payable,  (ii)  positive  prior period  volume
      adjustments made by the operators on several wells during the three months
      ended June 30, 2005,  and (iii) the  successful  completion of several new
      wells during mid and late 2004.  These increases were partially  offset by
      (i)  normal  declines  in  production  and (ii) a  substantial  decline in
      production  during 2005 on one  significant  well  following a workover of
      that well  during  mid  2004.  The well with the  substantial  decline  in
      production  is not  expected  to return to its  previously  high levels of
      production. The average gas price increased to $6.10 per Mcf for the three
      months  ended June 30, 2005 from $5.70 per Mcf for the three  months ended
      June 30, 2004. Due to a gas imbalance  situation on one  significant  well
      discussed above, gas volumes for that well were recorded as a liability at
      a substantially lower rate per Mcf than the average price per Mcf received
      by the P-6  Partnership  during the three months ended June 30, 2004. This
      resulted in a higher average price per Mcf for the three months ended June
      30, 2004 than if the  liability  had not been  recorded.  No such material
      adjustments were recorded during the three months ended June 30, 2005.


                                      -50-


      The  decrease in  production  expenses was  primarily  due to (i) workover
      expenses  incurred on several wells during the three months ended June 30,
      2004 and (ii) a decrease in repair and  maintenance  expenses  incurred on
      several  other  wells  during  the three  months  ended  June 30,  2005 as
      compared to the three  months ended June 20, 2004.  These  decreases  were
      partially offset by (i) workover expenses incurred on one significant well
      during  the three  months  ended  June 30,  2005 and (ii) an  increase  in
      production taxes associated with the increase in oil and gas sales.

      Depletion of Net Profits Interests increased $15,267 (42.0%) for the three
      months  ended June 30, 2005 as compared to the three months ended June 30,
      2004.  This increase was  primarily  due to an increase in depletable  Net
      Profits  Interests  during 2005 primarily due to the  recompletion  of one
      significant  well,  which  increase was partially  offset by several wells
      being fully  depleted  during the three  months ended June 30, 2004 due to
      the lack of  remaining  reserves.  As a percentage  of Net  Profits,  this
      expense  increased  to 7.7% for the three  months ended June 30, 2005 from
      6.7% for the three months ended June 30, 2004.  This  percentage  increase
      was  primarily  due to the dollar  increase  in  depletion  of Net Profits
      Interests.

      General and administrative expenses decreased $14,551 for the three months
      ended June 30, 2005 as compared to the three  months  ended June 30, 2004.
      As a percentage of Net Profits,  these expenses  decreased to 6.0% for the
      three  months  ended June 30, 2005 from 10.1% for the three  months  ended
      June 30,  2004.  This  percentage  decrease was  primarily  due to (i) the
      dollar  decrease  in  general  and  administrative  expenses  and (ii) the
      increase in Net Profits.

      Average price/Mcf                           $     5.82     $     5.17

      As shown in the table above,  total Net Profits increased $178,878 (16.6%)
      for the six months ended June 30, 2005 as compared to the six months ended
      June 30, 2004. Of this increase,  approximately  (i) $88,000 and $146,000,
      respectively,  were related to increases in the average  prices of oil and
      gas sold and (ii)  $2,000  was  related to an  increase  in volumes of oil
      sold. These increases were


                                      -51-


      partially  offset by decreases of  approximately  (i) $50,000 related to a
      decrease in volumes of gas sold and (ii) $7,000  related to an increase in
      production  expenses.  Volumes of oil sold  increased  45  barrels,  while
      volumes of gas sold decreased  9,726 Mcf for the six months ended June 30,
      2005 as compared to the six months ended June 30, 2004.

      The increase in volumes of oil sold was primarily due to a positive  prior
      period  volume  adjustment  made by the operator on one  significant  well
      during  the  six  months   ended  June  30,  2005,   which   increase  was
      substantially  offset by normal  declines in  production.  The decrease in
      volumes of gas sold was primarily due to (i) normal declines in production
      and  (ii)  a  substantial   decline  in  production  during  2005  on  one
      significant  well  following a workover of that well during mid 2004.  The
      well with the substantial  decline in production is not expected to return
      to  its  previously  high  levels  of  production.  These  decreases  were
      partially  offset by (i) downward  revisions in the estimates of remaining
      gas reserves  during the six months ended June 30, 2004 on one significant
      well resulting in the P-6 Partnership becoming over produced past ultimate
      reserves thereby  increasing gas imbalance payable and (ii) the successful
      completion of several new wells during mid and late 2004.  The average gas
      price  increased  to $5.82 per Mcf for the six months  ended June 30, 2005
      from $5.17 per Mcf for the six months  ended June 30,  2004.  Due to a gas
      imbalance  situation on one significant  well discussed above, gas volumes
      for that well were recorded as a liability at a  substantially  lower rate
      per Mcf than the average  price per Mcf  received  by the P-6  Partnership
      during  the six months  ended June 30,  2004.  This  resulted  in a higher
      average  price per Mcf for the six months  ended June 30, 2004 than if the
      liability  had not  been  recorded.  No  such  material  adjustments  were
      recorded during the six months ended June 30, 2005.

      The  increase in  production  expenses was  primarily  due to (i) workover
      expenses incurred on one significant well during the six months ended June
      30, 2005 and (ii) an  increase in  production  taxes  associated  with the
      increase in oil and gas sales.  These  increases were partially  offset by
      (i)  workover  expenses  incurred on several  wells  during the six months
      ended June 30, 2004 and (ii) a decrease in repair and maintenance expenses
      incurred on several  other wells during the six months ended June 30, 2005
      as compared to the six months ended June 20, 2004.




                                      -52-



      Depletion of Net Profits  Interests  increased  $8,133 (11.2%) for the six
      months  ended June 30, 2005 as  compared to the six months  ended June 30,
      2004.  This increase was  primarily  due to an increase in depletable  Net
      Profits  Interests  during 2005 primarily due to the  recompletion  of one
      significant  well. This increase was partially offset by (i) several wells
      being fully depleted  during the six months ended June 30, 2004 due to the
      lack of  remaining  reserves and (ii) the decrease in volumes of gas sold.
      As a percentage of Net Profits, this expense decreased to 6.4% for the six
      months  ended June 30,  2005 from 6.7% for the six  months  ended June 30,
      2004.

      General and  administrative  expenses  increased $1,557 for the six months
      ended June 30, 2005 as compared to the six months ended June 30, 2004.  As
      a percentage of Net Profits,  these expenses decreased to 8.1% for the six
      months  ended June 30,  2005 from 9.3% for the six  months  ended June 30,
      2004.  This  percentage  decrease was primarily due to the increase in Net
      Profits.

      Cumulative cash  distributions  to the Limited  Partners  through June 30,
      2005  were   $20,188,248   or  141.14%  of   Limited   Partners'   capital
      contribution.
