Partnership  as of June 30, 2001 and for the three and six months ended June 30,
2001 and 2000 include all  adjustments  and accruals  consisting  only of normal
recurring accrual adjustments which are necessary for a fair presentation of the
results for the  interim  period.  These  interim  results  are not  necessarily

Item 2.     Management's Discussion and Analysis of Financial Condition
               and Results of Operations (1)

Results of Operations

Six months ended June 30, 2001 compared with six months ended
  June 30, 2000

Revenues:

The  Partnership's  oil and gas revenues  decreased 1% to $1,086,570 for the six
months  ended June 30,  2001 as compared  to  $1,095,887  for the same period in
2000.  The decrease in revenues  resulted from a decline in production and lower
average prices  received for oil,  offset by higher average prices  received for
gas and NGLs.  For the six months ended  June 30,  2001,  23,078 barrels of oil,

                                        7

<PAGE>



10,759 barrels of natural gas liquids  ("NGLs") and 56,204 mcf of gas were sold,
or 43,204 barrel of oil equivalents ("BOEs").  For the six months ended June 30,
2000,  25,927 barrels of oil,  16,013 barrels of NGLs and 70,252 mcf of gas were
sold, or 53,649 BOEs.

The average price received per barrel of oil decreased  $.15, or 1%, from $27.78
for the six months  ended June 30,  2000 to $27.63 for the same  period in 2001.
The average  price  received per barrel of NGLs  increased  $2.54,  or 18%, from
$14.10  during the six months  ended June 30, 2000 to $16.64 for the same period
in 2001.  The average price  received per mcf of gas  increased  125% from $2.13
during the six months  ended June 30, 2000 to $4.80 for the same period in 2001.
The market price for oil and gas has been extremely  volatile in the past decade
and  management  expects  a certain  amount of  volatility  to  continue  in the
foreseeable  future.  The  Partnership may therefore sell its future oil and gas
production at average  prices lower or higher than that received  during the six
months ended June 30, 2001.

A gain on disposition of assets of $10,923 was recognized  during the six months
ended June 30, 2001 from salvage income  received on a well that was plugged and
abandoned  in the prior year.  A gain of $5,351 was  recognized  during the same
period ended June 30, 2000 from equipment  credits  received on a fully depleted
well.

Costs and Expenses:

Total costs and expenses increased to $673,377 for the six months ended June 30,
2001 as  compared  to  $567,246  for the same  period in 2000,  an  increase  of
$106,131,  or 19%.  This  increase  resulted  from higher  production  costs and
general and administrative expenses ("G&A"), offset by a decline in depletion.

Production  costs  were  $584,983  for the six months  ended  June 30,  2001 and
$480,127 for the same period in 2000 resulting in a $104,856  increase,  or 22%.
The increase was primarily due to additional workover and well maintenance costs
incurred to stimulate production.

G&A's  components are independent  accounting and engineering  fees and managing
general partner personnel and operating costs. During this period, G&A increased
5% from  $34,788 for the six months  ended June 30, 2000 to $36,427 for the same
period in 2001, primarily due to increased audit and tax fees.

Depletion  was  $51,967  for the six months  ended June 30,  2001 as compared to
$52,331 for the same period in 2000,  a decrease of $364,  or 1%. This  decrease
was primarily due to a reduction in the  Partnership's net depletable basis from
charges taken in accordance with Statement of Financial Accounting Standards No.
121,  "Accounting  for the  Impairment of Long-Lived  Assets and for Long- Lived
Assets to be Disposed Of" ("SFAS  121") during the fourth  quarter of 2000 and a
decline in oil  production  of 2,849  barrels for the six months  ended June 30,
2001 as compared to the same period in 2000.

Three months ended June 30, 2001 compared with three months ended June 30, 2000

Revenues:

The  Partnership's  oil and gas revenues  decreased 5% to $519,120 for the three
months  ended June 30, 2001 as compared to $545,418 for the same period in 2000.
The decrease in revenues resulted from a decline in production and lower average
prices  received for oil,  offset by higher average prices  received for gas and
NGLs.  For the three months ended June 30, 2001,  12,473  barrels of oil,  5,587
barrels of NGLs and 26,602 mcf of gas were sold,  or 22,494 BOEs.  For the three
months ended June 30, 2000,  12,194  barrels of oil,  7,964  barrels of NGLs and
34,873 mcf of gas were sold, or 25,970 BOEs.

The average price received per barrel of oil decreased  $.92, or 3%, from $27.91
for the three  months  ended June 30, 2000 to $26.99 for the three  months ended
June 30, 2001. The average price received per barrel of NGLs increased  slightly
from $14.72  during the three  months ended June 30, 2000 to $14.76 for the same
period in 2001.  The average  price  received per mcf of gas  increased 49% from
$2.52  during the three  months ended June 30, 2000 to $3.76 for the same period
in 2001.

A gain on  disposition  of assets of  $10,923  was  recognized  during the three
months  ended June 30,  2001 from  salvage  income  received  on a well that was
plugged and abandoned in the prior year. A gain of $1,428 was recognized  during
the same period ended June 30, 2000 from equipment  credits  received on a fully
depleted well.

Costs and Expenses:

Total costs and  expenses  increased to $349,935 for the three months ended June
30, 2001 as compared  to  $287,547  for the same period in 2000,  an increase of
$62,388, or 22%. This increase was due to higher production costs and depletion,
offset by a decline in G&A.

Production  costs were  $306,551  for the three  months  ended June 30, 2001 and
$247,177 for the same period in 2000  resulting in a $59,374  increase,  or 24%.
This  increase was primarily  due to  additional  workover and well  maintenance
costs incurred to stimulate production.

During this period,  G&A  decreased  11% from $17,899 for the three months ended
June 30, 2000 to $15,891 for the same period in 2001, primarily due to decreased
audit and tax fees.

Depletion  was $27,493 for the three  months  ended June 30, 2001 as compared to
$22,471  for the same  period in 2000,  an  increase  of  $5,022,  or 22%.  This
increase  was  primarily  due to a reduction  in proved  reserves for the period
ended  June 30,  2000 due to  lower  commodity  prices  and an  increase  in oil
production  of 279 barrels for the three months ended June 30, 2001  compared to
the same period in 2000.

Liquidity and Capital Resources

Net Cash Provided by Operating Activities

Net cash  provided by  operating  activities  increased  $21,840  during the six
months ended June 30, 2001 from the same period in 2000.  This  increase was due
to a reduction of $138,801 in working capital, offset by increases in production
costs of $104,856 and G&A expenses of $1,639 and a decline of $10,466 in oil and
gas sales receipts. The decrease in oil and gas receipts resulted from a decline
of $233,580 in production during 2001 as compared to the same period in 2000 and
a decline in oil prices of $3,664,  offset by an  increase in gas and NGL prices
of $226,778  during 2001. The increase in production  costs was primarily due to
additional  workover  and well  maintenance  costs  incurred to  stimulate  well
production.  The increase in G&A was  primarily  due to increased  audit and tax
fees.

Net Cash Provided by Investing Activities

The Partnership's investing activities during the six months ended June 30, 2001
and 2000 were for  expenditures  related to oil and gas  equipment  upgrades  on
active properties.

Proceeds from asset  disposition of $10,923 and $5,358 were received  during the
six months ended June 30, 2001 and 2000,  respectively.  The  proceeds  received
during the period in 2001 were due to salvage income  received on a well plugged
and abandoned in the prior year. The proceeds received during the period in 2000
were for equipment credits on active properties.

Net Cash Used in Financing Activities

For the six months ended June 30, 2001, cash  distributions to the partners were
$349,414,  of which $90,005 was distributed to the general partners and $259,409
to the  limited  partners.  For the  same  period  ended  June  30,  2000,  cash
distributions  to the partners were $574,504,  of which $144,738 was distributed
to the general partners and $429,766 to the limited partners.

For the three  months  ended June 30, 2001,  no  distributions  were made by the
partnership to its partners.  Subsequent to June 30, 2001 the cash  distribution
that  otherwise  would  have been  mailed to  partners  in late June was made to
holders  of  record  as of July 9, 2001 and was  mailed  on July 13,  2001.  For
further information, see "Proposal to acquire partnerships" below.

Proposal to acquire partnerships

On June 29, 2001,  Pioneer Natural Resources Company  ("Pioneer") filed with the
Securities and Exchange Commission  Amendment No. 1 to the Form S-4 Registration
Statement (File No. 333-59094) (the "preliminary  proxy  statement/prospectus"),
which  proposes an agreement and plan of merger among Pioneer,  Pioneer  Natural
Resources USA, Inc. ("Pioneer USA"), a wholly-owned  subsidiary of Pioneer,  and
46 Parker & Parsley limited  partnerships.  Each  partnership  that approves the
agreement and plan of merger and the other related  merger  proposals will merge
with and into Pioneer USA upon the closing of the transactions  described in the
preliminary proxy  statement/prospectus,  and the partnership  interests of each
such  partnership  will be converted  into the right to receive  Pioneer  common
stock.  The Partnership is one of the 46 Parker & Parsley  limited  partnerships


                                       10

that will be asked to approve the agreement and plan of merger.  The preliminary
proxy statement/prospectus is non-binding and is subject to, among other things,
consideration  of offers from third parties to purchase any  partnership  or its
assets and the majority  approval of the limited  partnership  interests in each
partnership.

Pioneer USA will solicit  proxies  from limited  partners to approve the mergers
only when the proxy  statement/prospectus  is final and declared  effective.  No
solicitation will be made using preliminary  materials.  Nonetheless,  copies of
the preliminary proxy  statement/prospectus  may be obtained without charge upon
request from Pioneer Natural Resources Company, 5205 North O'Connor Blvd., Suite
1400, Irving, Texas 75039, Attention: Investor Relations.

The limited partners are urged to read the proxy statement/prospectus of Pioneer
filed with the Securities and Exchange Commission, when it is finalized, because
it  contains  important  information  about  the  proposed  mergers,   including
information  about the direct and indirect  interests of Pioneer USA and Pioneer
in the mergers.  The limited  partners may also obtain the preliminary and (when
filed) final proxy statement/prospectus and other relevant documents relating to
the proposed mergers free through the internet web site that the Securities and
Exchange Commission maintains at www.sec.gov.
