        GEODYNE INSTITUTIONAL/PENSION ENERGY INCOME LIMITED PARTNERSHIPS
              CONDENSED NOTES TO THE COMBINED FINANCIAL STATEMENTS
                               SEPTEMBER 30, 2005
                                   (Unaudited)


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

      The combined balance sheets as of September 30, 2005,  combined statements
      of operations  for the three and nine months ended  September 30, 2005 and
      2004,  and  combined  statements  of cash flows for the nine months  ended
      September 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 September 30, 2005,  the combined  results of operations  for the three
      and nine months ended  September 30, 2005 and 2004,  and the combined cash
      flows for the nine months ended September 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  September  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.
      Estimated abandonment dates will be revised in the future based on changes
      to related  economic lives,  which vary with product prices and production
      costs.  Estimated  plugging costs may also be adjusted to reflect changing
      industry experience.  The Partnerships' asset retirement  obligations were
      revised  upward for the three  months ended  September  30, 2005 due to an
      increase in both the labor and

                                      -23-


      rig costs associated with plugging wells. Cash flows would not be affected
      until wells are actually plugged and abandoned.

      The asset  retirement  obligation will be adjusted upwards each quarter in
      order to recognize accretion of the time-related  discount factor. For the
      nine months ended  September  30, 2005,  the P-1,  P-3,  P-4, P-5, and P-6
      Partnerships recognized approximately $13,000,  $23,000, $21,000, $23,000,
      and $76,000 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 nine months ended September 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 September 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.

      Pursuant to the terms of the  Partnerships'  partnership  agreements  (the
      "Partnership Agreements"),  the Partnerships are scheduled to terminate on
      December 31, 2005.  However,  the Partnership  Agreements provide that the
      General  Partner  may extend the term of each  Partnership  for up to five
      periods of two years each. As of the date of this  Quarterly  Report,  the
      General Partner has extended the terms of the Partnerships for their first
      two year extension period to December 31, 2007.


                                      -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.
      Estimated abandonment dates will be revised in the future based on changes
      to related  economic lives,  which vary with product prices and production
      costs.  Estimated  plugging costs may also be adjusted to reflect changing
      industry experience.  The Partnerships' asset retirement  obligations were
      revised  upward for the three  months ended  September  30, 2005 due to an
      increase in both the labor and rig costs  associated  with plugging wells.
      Cash flows would not be  affected  until  wells are  actually  plugged and
      abandoned.


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

                                      -32-


      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.

      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 September  30, 2005,  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


                                      -38-


      market prices for oil and gas production subsequent to September 30, 2005.
      There can be no  assurance  that the prices  used in  calculating  the net
      present value of the  Partnerships'  proved reserves at September 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;
                                      -39-


            *     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 and the impact of  weather-related events;
            *     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.

      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.

      Average price/Bbl                           $  58.40         $  39.47
      Average price/Mcf                           $   6.96         $   4.57

      As shown in the table above,  total Net Profits increased $235,630 (60.5%)
      for the three  months  ended  September  30, 2005 as compared to the three
      months ended  September  30, 2004.  Of this  increase,  approximately  (i)
      $88,000 and  $154,000,  respectively,  were  related to  increases  in the
      average prices of oil and gas sold, (ii) $18,000 was related to a decrease
      in  production  expenses,  and (iii) $15,000 was related to an increase in
      volumes of oil sold.  These increases were partially  offset by a decrease
      of approximately $39,000 related to a decrease in volumes of gas sold.

      Volumes  of oil sold  increased  382  barrels,  while  volumes of gas sold
      decreased  8,580 Mcf for the three  months  ended  September  30,  2005 as
      compared to the three months  ended  September  30, 2004.  The increase in
      volumes of oil sold was primarily due to (i) the successful  completion of
      two new wells  during late 2004,  (ii) an increase  in  production  on one
      significant  well  following the  successful  workover of that well during
      late 2004, and (iii) a positive prior period volume adjustment made by the
      operator  on  another  significant  well  during  the three  months  ended
      September 30, 2005.  The decrease in volumes of gas sold was primarily due
      to (i) normal declines in production and (ii) positive prior period volume
      adjustments made by the operators on several wells during the three months
      ended  September  30,  2004.  The  decrease  in  production  expenses  was
      primarily  due to  workover  expenses  incurred on two  significant  wells
      during the three  months  ended  September  30,  2004.  This  decrease was
      partially  offset by (i) an increase in production  taxes  associated with
      the increase in oil and gas sales and (ii) workover  expenses  incurred on
      several wells during the three months ended September 30, 2005.

      Depletion of Net Profits Interests  increased $5,005 (24.4%) for the three
      months  ended  September  30, 2005 as compared to the three  months  ended
      September 30, 2004. Of this increase (i)  approximately  $8,000 was due to
      the  depletion  of  additional  Net Profits  Interests  as a result of the
      upward revision in the estimate of the asset  retirement  obligations,  of
      which approximately $5,000 was related to previously fully depleted wells,
      and (ii)  approximately  $2,000 was due to accretion  of these  additional
      asset retirement obligations. These increases were partially offset by the
      decrease in volumes of gas sold.  As a  percentage  of Net  Profits,  this
      expense decreased to 4.1%

                                      -41-


      for the three  months  ended  September  30,  2005 from 5.3% for the three
      months ended September 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
      three months ended  September  30, 2005 and 2004.  As a percentage  of Net
      Profits,  these  expenses  decreased  to 4.9% for the three  months  ended
      September  30, 2005 from 7.9% for the three  months  ended  September  30,
      2004.  This  percentage  decrease was primarily due to the increase in Net
      Profits.

      As shown in the table above,  total Net Profits increased $418,076 (35.0%)
      for the nine  months  ended  September  30,  2005 as  compared to the nine
      months ended  September  30, 2004.  Of this  increase,  approximately  (i)
      $226,000  and  $279,000,  respectively,  were  related to increases in the
      average  prices  of oil and gas sold  and (ii)  $3,000  was  related  to a
      decrease in production expenses.  These increases were partially offset by
      decreases of approximately  $4,000 and $86,000,  respectively,  related to
      decreases in volumes of oil and gas sold.

      Volumes  of oil and  gas  sold  decreased  106  barrels  and  18,515  Mcf,
      respectively,  for the nine months ended September 30, 2005 as compared to
      the nine months  ended  September  30,  2004. A decrease in volumes of oil
      sold primarily due to (i) a negative prior period volume  adjustment  made
      by the  operator on one  significant  well  during the nine  months  ended
      September 30, 2005, (ii) normal declines in production, and (iii) positive
      prior period  volume  adjustments  made by the  operators on several wells
      during the nine months ended September 30, 2004 was  substantially  offset
      by positive  prior  period  volume  adjustments  made by the  operators on
      several other wells during the nine months ended  September 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 nine months ended  September 30, 2005,  (ii) normal declines in
      production, and (iii) positive prior period volume adjustments made by the
      operators  on several  wells during the nine months  ended  September  30,
      2004. These decreases were partially offset by positive prior period

                                      -42-


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

      Depletion of Net Profits  Interests  increased $6,309 (12.0%) for the nine
      months  ended  September  30, 2005 as  compared  to the nine months  ended
      September 30, 2004. Of this increase (i)  approximately  $8,000 was due to
      the  depletion  of  additional  Net Profits  Interests  as a result of the
      upward revision in the estimate of the asset  retirement  obligations,  of
      which approximately $5,000 was related to previously fully depleted wells,
      and (ii)  approximately  $2,000 was due to accretion  of these  additional
      asset retirement obligations. 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 nine months  ended  September  30,
      2005  from  4.4%  for the nine  months  ended  September  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
      nine months ended  September  30, 2005 and 2004.  As a  percentage  of Net
      Profits,  these  expenses  decreased  to 7.0%  for the nine  months  ended
      September 30, 2005 from 9.4% for the nine months ended September 30, 2004.
      This percentage decrease was primarily due to the increase in Net Profits.

      Cumulative cash  distributions to the Limited  Partners through  September
      30,  2005  were  $17,819,558  or  164.88%  of  Limited  Partners'  capital
      contributions.

      As shown in the table above,  total Net Profits increased $326,871 (57.9%)
      for the three  months  ended  September  30, 2005 as compared to the three
      months ended  September  30, 2004.  Of this  increase,  approximately  (i)
      $114,000  and  $238,000,  respectively,  were  related to increases in the
      average  prices  of oil and gas  sold,  (ii)  $19,000  was  related  to an
      increase  in  volumes  of oil sold,  and (iii)  $16,000  was  related to a
      decrease in production expenses.  These increases were partially offset by
      a decrease of  approximately  $60,000  related to a decrease in volumes of
      gas sold.

      Volumes  of oil sold  increased  482  barrels,  while  volumes of gas sold
      decreased  12,823 Mcf for the three  months  ended  September  30, 2005 as
      compared to the three months  ended  September  30, 2004.  The increase in
      volumes of oil sold was primarily due to (i) the successful  completion of

      to (i) normal declines in production and (ii) positive prior period volume
      adjustments made by the operators on several wells during the three months
      ended  September  30,  2004.  The  decrease  in  production  expenses  was

      several wells during the three months ended September 30, 2005.

      Depletion of Net Profits Interests decreased $55,997 (56.3%) for the three
      months  ended  September  30, 2005 as compared to the three  months  ended
      September 30, 2004. This decrease was primarily due to (i) one significant
      well being fully depleted during the three months ended September 30, 2004
      due to the lack of remaining  reserves and (ii) the decrease in volumes of
      gas sold.  These  decreases  were  partially  offset by  increases  of (i)
      approximately  $15,000  due to the  depletion  of  additional  Net Profits
      Interests as a result of the upward  revision in the estimate of the asset
      retirement  obligations,  of which  approximately  $8,000  was  related to
      previously  fully depleted  wells,  and (ii)  approximately  $4,000 due to
      accretion of these additional asset retirement

      obligations.  As a percentage  of Net Profits,  this expense  decreased to
      4.9% for the three  months  ended  September  30,  2005 from 17.6% for the
      three  months  ended  September  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 remained  relatively constant for the

      As shown in the table above,  total Net Profits increased $569,139 (32.6%)
      for the nine  months  ended  September  30,  2005 as  compared to the nine
      months ended September 30, 2004. Of this increase,  approximately $292,000
      and  $427,000,  respectively,  were  related to  increases  in the average
      prices of oil and gas  sold.  These  increases  were  partially  offset by
      decreases of approximately $5,000 and $145,000,  respectively,  related to
      decreases in volumes of oil and gas sold.

      Volumes  of oil and  gas  sold  decreased  134  barrels  and  30,420  Mcf,
      respectively,  for the nine months ended September 30, 2005 as compared to
      the nine months ended  September 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 nine months ended
      September 30, 2005, (ii) normal declines in production, and (iii) positive
      prior period  volume  adjustments  made by the  operators on several wells
      during the nine months ended  September  30, 2004.  These  decreases  were
      substantially  offset by positive prior period volume  adjustments made by
      the  operators  on  several  other  wells  during  the nine  months  ended
      September 30, 2005.  The decrease in volumes of gas sold was primarily due
      to (i) normal declines in production,  (ii) a negative prior period volume
      adjustment  made by the operator on one  significant  well during the nine
      months ended  September 30, 2005,  and (iii)  positive prior period volume
      adjustments made by the

                                      -45-


      operators  on several  wells during the nine months  ended  September  30,
      2004.  These  decreasee  were  partially  offset by positive  prior period
      volume  adjustments made by the operators on several wells during the nine
      months  ended  September  30,  2005.  An increase in  production  expenses
      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 nine  months  ended  September  30,  2005,  and (iii) an
      increase in salt water disposal  expenses incurred on one significant well
      during the nine months  ended  September  30, 2005 as compared to the nine
      months ended September 30, 2004 was  substantially  offset by (i) workover
      expenses  incurred on several wells during the nine months ended September
      30, 2004 and (ii) the receipt of ad valorem tax credits on one significant
      well during the nine months ended September 30, 2005.

      Depletion of Net Profits Interests  decreased $53,051 (35.8%) for the nine
      months  ended  September  30, 2005 as  compared  to the nine months  ended
      September 30, 2004. This decrease was primarily due to (i) one significant
      well being fully depleted  during the nine months ended September 30, 2004
      due to the lack of remaining reserves and (ii) the decreases in volumes of
      oil and gas sold.  These  decreases were partially  offset by increases of
      (i)  approximately  $15,000 due to the depletion of additional Net Profits
      Interests as a result of the upward  revision in the estimate of the asset
      retirement  obligations,  of which  approximately  $8,000  was  related to
      previously  fully depleted  wells,  and (ii)  approximately  $4,000 due to
      accretion  of  these  additional  asset  retirement   obligations.   As  a
      percentage  of Net Profits,  this  expense  decreased to 4.1% for the nine
      months  ended  September  30,  2005  from 8.5% for the nine  months  ended
      September 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 remained  relatively constant for the
      nine months ended  September  30, 2005 and 2004.  As a  percentage  of Net
      Profits,  these  expenses  decreased  to 7.1%  for the nine  months  ended
      September 30, 2005 from 9.4% for the nine months ended September 30, 2004.
      This percentage decrease was primarily due to the increase in Net Profits.

      Cumulative cash  distributions to the Limited  Partners through  September
      30,  2005  were  $24,936,401  or  147.00%  of  Limited  Partners'  capital
      contributions.

      As shown in the table above,  total Net Profits  increased $43,484 (10.5%)
      for the three  months  ended  September  30, 2005 as compared to the three
      months ended September 30, 2004. Of this increase,  approximately  $71,000
      and  $122,000,  respectively,  were  related to  increases  in the average
      prices of oil and gas  sold.  These  increases  were  partially  offset by
      decreases of approximately (i) $37,000 and $62,000, respectively,  related
      to decreases in volumes of oil and gas sold and (ii) $51,000 related to an
      increase in production expenses.

      Volumes  of oil and  gas  sold  decreased  884  barrels  and  11,591  Mcf,
      respectively, for the three months ended September 30, 2005 as compared to
      the three months ended  September 30, 2004. The decrease in volumes of oil
      sold was primarily due to (i) normal  declines in production  and (ii) the
      shutting-in of one significant  well during mid 2005 in order to perform a
      workover.  As of the date of this Quarterly  Report,  the shut-in well has
      returned to production at a lower rate than  previously  experienced.  The
      decrease in volumes of gas sold was primarily  due to (i) normal  declines
      in production,  (ii) positive prior period volume  adjustments made by the
      operators on two significant wells during the three months ended September
      30, 2004, and (iii) the shutting-in of two significant  wells during early
      2005 in  order to  perform  workovers.  As of the  date of this  Quarterly
      Report,  the operator has not yet  determined  when the shut-in wells will
      return to  production.  The increase in production  expenses was primarily
      due to (i) workover  expenses incurred on two significant wells during the
      three months ended  September  30,  2005,  (ii) an increase in  production
      taxes  associated  with the increase in oil and gas sales,  and (iii) salt
      water disposal  expenses incurred on several wells during the three months
      ended September 30, 2005.

      Depletion  of Net Profits  Interests  increased  $16,240  (128.7%) for the
      three  months  ended  September  30, 2005 as compared to the three  months
      ended September 30, 2004. Of this increase (i)  approximately  $17,000 was
      due to the  depletion of additional  Net Profits  Interests as a result of
      the upward revision in the estimate of the asset  retirement  obligations,
      of which  approximately  $10,000 was related to previously  fully depleted
      wells, and (ii) approximately

                                      -47-


      $2,000  was  due  to  accretion  of  these   additional  asset  retirement
      obligations. These increases were partially offset by (i) the decreases in
      volumes  of oil and gas sold and (ii) one  significant  well  being  fully
      depleted  during the nine months ended  September 30, 2004 due to the lack
      of  remaining  reserves.  As a  percentage  of Net  Profits,  this expense
      increased to 6.3% for the three months ended  September 30, 2005 from 3.0%
      for the three months ended September 30, 2004.  This  percentage  increase
      was  primarily  due to the dollar  increase  in  depletion  of Net Profits
      Interests.

      General and administrative  expenses remained  relatively constant for the
      three months ended  September  30, 2005 and 2004.  As a percentage  of Net
      Profits,  these  expenses  decreased  to 7.8% for the three  months  ended

      As shown  in the  table  above,  total  Net  Profits  remained  relatively
      constant for the nine months ended September 30, 2005 and 2004.  Decreases
      of  approximately  (i) $102,000  and  $154,000,  respectively,  related to
      decreases in volumes of oil and gas sold and (ii)  $128,000  related to an
      increase in production expenses were substantially  offset by increases of
      approximately $175,000 and $205,000, respectively, related to increases in
      the average prices of oil and gas sold.

      Volumes  of oil and gas sold  decreased  2,713  barrels  and  27,871  Mcf,
      respectively,  for the nine months ended September 30, 2005 as compared to
      the nine months ended  September 30, 2004.  The decrease in volumes of oil
      sold was primarily due to (i) the  shutting-in  of two  significant  wells
      during late 2004 and early to mid 2005 in order to perform workovers, (ii)
      the  shutting-in  of two 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 nine months ended  September
      30, 2004, (ii) normal declines in production, and

                                      -48-


      (iii) the shutting-in of two significant  wells during early 2005 in order
      to  perform  workovers.  As of the  date of  this  Quarterly  Report,  the
      operator  has not yet  determined  when the  shut-in  wells will return to
      production.  The increase in production  expenses was primarily due to (i)
      workover  expenses  incurred on several wells during the nine months ended
      September 30, 2005, (ii) an increase in production  taxes  associated with
      the  increase  in oil and gas  sales,  and (iii) a positive  prior  period
      production tax  adjustment  made by the operator on one  significant  well
      during the nine months ended September 30, 2005.

      Depletion of Net Profits Interests  decreased $20,207 (28.1%) for the nine
      months  ended  September  30, 2005 as  compared  to the nine months  ended
      September 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) one
      significant  well  being  fully  depleted  during  the nine  months  ended
      September 30, 2004 due to the lack of remaining reserves.  These decreases
      were partially offset by increases of (i) approximately $17,000 due to the
      depletion of  additional  Net Profits  Interests as a result of the upward
      revision in the  estimate of the asset  retirement  obligations,  of which
      approximately  $10,000 was related to previously fully depleted wells, and
      (ii)  approximately  $2,000 due to  accretion  of these  additional  asset
      retirement  obligations.  As a  percentage  of Net  Profits,  this expense
      decreased to 4.1% for the nine months ended  September  30, 2005 from 5.7%
      for the nine months ended September 30, 2004. This percentage decrease was
      primarily  due  to  the  dollar  decrease  in  depletion  of  Net  Profits
      Interests.

      General and  administrative  expenses increased $1,853 (1.5%) for the nine
      months  ended  September  30, 2005 as  compared  to the nine months  ended
      September  30,  2004.  As a  percentage  of Net  Profits,  these  expenses
      increased to 10.3% for the nine months ended September 30, 2005 from 10.1%
      for the nine months ended September 30, 2004.

      Cumulative cash  distributions to the Limited  Partners through  September

      As shown in the table above,  total Net Profits increased $178,700 (68.1%)
      for the three  months  ended  September  30, 2005 as compared to the three
      months ended  September  30, 2004.  Of this  increase,  approximately  (i)
      $20,000 and  $158,000,  respectively,  were  related to  increases  in the
      average  prices of oil and gas sold and (ii)  $24,000  was  related  to an
      increase in volumes of oil sold.  These increases were partially offset by
      decreases of approximately (i) $13,000 related to a decrease in volumes of
      gas sold and (ii) $10,000 related to an increase in production expenses.

      Volumes  of oil sold  increased  552  barrels,  while  volumes of gas sold
      decreased  2,919 Mcf for the three  months  ended  September  30,  2005 as
      compared to the three months  ended  September  30, 2004.  The increase 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
      three months ended September 30, 2005,  (ii) the successful  completion of
      two new  wells  during  early  and mid  2005,  and  (iii)  the  successful
      completion of another new well during mid 2004. The decrease in volumes of
      gas sold was primarily due to normal declines in production. This decrease
      was  partially  offset by (i) the  successful  completion of two new wells
      during mid 2004, (ii) the successful completion of another new well during
      early 2005, and (iii) positive prior period volume adjustments made by the
      operators on two significant wells during the three months ended September
      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 one significant well during the
      three months ended September 30, 2005, and (iii) an increase in repair and
      maintenance expenses incurred on another significant well during the three
      months  ended  September  30, 2005 as compared to the three  months  ended
      September 30, 2004.  These  increases  were  partially  offset by workover
      expenses  incurred on two significant  wells during the three months ended
      September 30, 2004.

      Depletion  of Net Profits  Interests  increased  $28,492  (291.5%) for the
      three  months  ended  September  30, 2005 as compared to the three  months
      ended September 30, 2004. Of this increase (i)  approximately  $18,000 was
      due to the  depletion of additional  Net Profits  Interests as a result of
      the upward revision in the estimate of the asset  retirement  obligations,
      of which  approximately  $14,000 was related to previously  fully depleted
      wells,  and  (ii)  approximately  $2,000  was due to  accretion  of  these
      additional asset retirement obligations. This increase was also due to two
      significant  wells  being  fully  depleted  during the nine  months  ended
      September 30, 2005 due to the lack of remaining reserves.  As a percentage
      of Net Profits,  this expense increased to 8.7% for the three months ended
      September  30, 2005 from 3.7% for the three  months  ended  September  30,
      2004. This percentage increase was primarily due to the dollar increase in
      depletion of Net Profits Interests.

      General and administrative  expenses remained  relatively constant for the
      three months ended  September  30, 2005 and 2004.  As a percentage  of Net
      Profits,  these  expenses  decreased  to 7.6% for the three  months  ended
      September  30, 2005 from 12.7% for the three  months ended  September  30,
      2004.  This  percentage  decrease was primarily due to the increase in Net
      Profits.

      Average price/Mcf                         $     6.25         $   5.08

      As shown in the table above,  total Net Profits increased $290,599 (30.9%)
      for the nine  months  ended  September  30,  2005 as  compared to the nine
      months ended  September  30, 2004.  Of this  increase,  approximately  (i)
      $56,000 and  $247,000,  respectively,  were  related to  increases  in the
      average   prices  of  oil  and  gas  sold  and  (ii)  $4,000  and  $5,000,
      respectively,  were  related  to the  increases  in volumes of oil and gas
      sold.

      Volumes  of oil  and  gas  sold  increased  122  barrels  and  1,049  Mcf,
      respectively,  for the nine months ended September 30, 2005 as compared to
      the nine months ended  September 30, 2004.  The increase 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 nine months
      ended September 30, 2005, (ii) the successful  completion of two new wells
      during early and mid 2005, and (iii) the successful  completion of another
      new well during mid 2004.


                                      -51-

      The  increase  in volumes of gas sold was  primarily  due to (i)  downward
      revisions  in the  estimates of  remaining  gas  reserves  during the nine
      months ended September 30, 2004 on one  significant  well resulting in the
      P-5  Partnership  becoming over  produced in excess of estimated  ultimate
      reserves  thereby  increasing gas imbalance  payable,  (ii) the successful
      completion  of several new wells  during mid and late 2004,  and (iii) the
      successful  completion of one new well during early 2005.  These increases
      were  substantially  offset by (i) normal  declines in production,  (ii) a
      substantial  decline in  production  during 2005 on one  significant  well
      following  a  workover  of that  well  during  mid  2004,  and  (iii)  the
      shutting-in of one significant well during the nine months ended September
      30, 2005 in order to perform a workover.  As of the date of this Quarterly
      Report,  the shut-in  well is  producing  at a lower rate than  previously
      experienced.

      The average gas price increased to $6.25 per Mcf for the nine months ended
      September 30, 2005 from $5.08 per Mcf for the nine months ended  September
      30, 2004. Due to the gas imbalance  situation on one  significant  well as
      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 nine months ended  September 30, 2004.
      This resulted in a higher  average price per Mcf for the nine months ended
      September 30, 2004 than if the liability  had not been  recorded.  No such
      material  adjustments were recorded during the nine months ended September
      30, 2005.

      Depletion of Net Profits Interests  increased $14,132 (22.3%) for the nine
      months  ended  September  30, 2005 as  compared  to the nine months  ended
      September 30, 2004. Of this increase (i) approximately  $18,000 was due to
      the  depletion  of  additional  Net Profits  Interests  as a result of the
      upward revision in the estimate of the asset  retirement  obligations,  of
      which  approximately  $14,000 was  related to  previously  fully  depleted
      wells,  and  (ii)  approximately  $2,000  was due to  accretion  of  these
      additional asset retirement obligations.  This increase was also due to an
      increase in depletable Net Profits  Interests during 2005 primarily due to
      the drilling of two  developmental  wells.  These increases were partially
      offset by two  significant  wells  being  fully  depleted  during the nine
      months ended September 30, 2004 due to the lack of remaining reserves.  As
      a percentage of Net Profits,  this expense  decreased to 6.3% for the nine
      months  ended  September  30,  2005  from 6.7% for the nine  months  ended
      September 30, 2004.

                                      -52-


      General and  administrative  expenses increased $1,935 (1.6%) for the nine
      months  ended  September  30, 2005 as  compared  to the nine months  ended
      September  30,  2004.  As a  percentage  of Net  Profits,  these  expenses
      decreased to 9.9% for the nine months ended  September 30, 2005 from 12.7%
      for the nine months ended September 30, 2004. This percentage decrease was
      primarily due to the increase in Net Profits.

      Cumulative cash  distributions to the Limited  Partners through  September
      30,  2005  were  $13,950,759  or  117.78%  of  Limited  Partners'  capital
      contributions.

      As shown in the table above,  total Net Profits increased $315,884 (94.0%)
      for the three  months  ended  September  30, 2005 as compared to the three
      months ended  September  30, 2004.  Of this  increase,  approximately  (i)
      $47,000 and  $161,000,  respectively,  were  related to  increases  in the
      average  prices  of oil  and  gas  sold  and  (ii)  $94,000  and  $34,000,
      respectively,  were  related to  increases in volumes of oil and gas sold.
      These  increases  were  partially  offset by a decrease  of  approximately
      $20,000 related to an increase in production expenses.

      Volumes  of oil and gas  sold  increased  3,350  barrels  and  6,286  Mcf,
      respectively, for the three months ended September 30, 2005 as compared to
      the three months ended  September 30, 2004. The increase in volumes of oil
      sold was primarily due to (i) a substantial  negative  prior period volume
      adjustment made by the operator on one  significant  well during the three
      months ended September 30, 2004, (ii) the successful completion of two new
      wells during mid 2005, and (iii) the successful completion of one new well
      during late 2004.  Without the negative prior period adjustment volumes of
      oil sold for the three  months  ended  September  30, 2004 would have been
      1,629 barrels with an average price of $42.63.  The increase 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 three
      months ended  September 30, 2004 and (ii) an increase in production on one
      significant well following the successful workover of that well during mid
      and late 2004. These increases were partially offset by normal declines in
      production. The

                                      -53-

      increase  in  production  expenses  was  primarily  due to an  increase in
      production taxes associated with the increase in oil and gas sales.

      Depletion of Net Profits  Interests  increased  $104,653  (456.9%) for the
      three  months  ended  September  30, 2005 as compared to the three  months
      ended September 30, 2004. Of this increase (i)  approximately  $62,000 was
      due to the  depletion of additional  Net Profits  Interests as a result of
      the upward revision in the estimate of the asset  retirement  obligations,
      of which  approximately  $45,000 was related to previously  fully depleted
      wells,  and  (ii)  approximately  $7,000  was due to  accretion  of  these
      additional asset retirement obligations.  This increase was also due to an
      increase in depletable Net Profits  Interests during 2005 primarily due to
      the recompletion of two significant wells. As a percentage of Net Profits,
      this expense  increased to 19.6% for the three months ended  September 30,
      2005  from  6.8% for the three  months  ended  September  30,  2004.  This
      percentage  increase was primarily due to the dollar increase in depletion
      of Net Profits Interests.

      General and administrative  expenses remained  relatively constant for the
      three months ended  September  30, 2005 and 2004.  As a percentage  of Net
      Profits,  these  expenses  decreased  to 6.2% for the three  months  ended
      September  30, 2005 from 11.9% for the three  months ended  September  30,
      2004.  This  percentage  decrease was primarily due to the increase in Net
      Profits.

      for the nine  months  ended  September  30,  2005 as  compared to the nine
      months ended  September  30, 2004.  Of this  increase,  approximately  (i)
      $87,000 and  $309,000,  respectively,  were  related to  increases  in the
      average  prices of oil and gas sold and (ii)  $144,000  was  related to an
      increase in volumes of oil sold.  These increases were partially offset by
      a decrease of  approximately  $18,000  related to a decrease in volumes of
      gas sold.

      Volumes of oil sold  increased  3,395  barrels,  while volumes of gas sold
      decreased  3,440  Mcf for the nine  months  ended  September  30,  2005 as
      compared to the nine months ended


                                      -54-



      September 30, 2004.  The increase 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 nine months ended September 30, 2004, (ii)
      the successful  completion of two new wells during mid 2005, and (iii) the
      successful  completion  of one new well during late 2004.  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. These
      decreases were partially offset by (i) downward revisions in the estimates
      of remaining gas reserves  during the nine months ended September 30, 2004
      on one  significant  well resulting in the P-6  Partnership  becoming over
      produced in excess of estimated  ultimate reserves thereby  increasing gas
      imbalance  payable and (ii) a negative prior period volume adjustment made
      by the  operator on one  significant  well  during the nine  months  ended
      September 30, 2004.

      The average gas price increased to $6.18 per Mcf for the nine months ended
      September 30, 2005 from $5.24 per Mcf for the nine months ended  September
      30, 2004. Due to the gas imbalance  situation on one  significant  well as
      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 nine months ended  September 30, 2004.
      This resulted in a higher  average price per Mcf for the nine months ended
      September 30, 2004 than if the liability  had not been  recorded.  No such
      material  adjustments were recorded during the nine months ended September
      30, 2005.

      Depletion of Net Profits  Interests  increased  $112,786  (118.3%) for the
      nine months ended  September 30, 2005 as compared to the nine months ended
      September 30, 2004. Of this increase (i) approximately  $62,000 was due to
      the  depletion  of  additional  Net Profits  Interests  as a result of the
      upward revision in the estimate of the asset  retirement  obligations,  of
      which  approximately  $45,000 was  related to  previously  fully  depleted
      wells,  and  (ii)  approximately  $7,000  was due to  accretion  of  these
      additional asset retirement obligations.  This increase was also due to an
      increase in depletable Net Profits  Interests during 2005 primarily due to
      the recompletion of two significant wells. As a percentage of Net Profits,
      this expense  increased to 10.9% for the nine months ended  September  30,
      2005  from  6.7%  for the nine  months  ended  September  30,  2004.  This
      percentage  increase was primarily due to the dollar increase in depletion
      of Net Profits Interests.

      decreased to 7.4% for the nine months ended  September  30, 2005 from 9.9%
      for the nine months ended September 30, 2004. This percentage decrease was
