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  increased 3% to $1,110,822 for the six
months  ended June 30,  2001 as compared  to  $1,082,369  for the same period in
2000. The increase in revenues  resulted from higher average prices received for
gas and NGLs,  offset  by a  decrease in  production and  lower  average  prices

                                       7

received for oil. For the six months ended June 30, 2001, 26,035 barrels of oil,
12,266 barrels of natural gas liquids  ("NGLs") and 57,564 mcf of gas were sold,
or 47,895 barrel of oil equivalents ("BOEs").  For the six months ended June 30,
2000,  26,759 barrels of oil,  16,307 barrels of NGLs and 68,163 mcf of gas were
sold, or 54,427 BOEs.

The average price received per barrel of oil decreased  $.61, or 2%, from $27.63
for the six months  ended June 30,  2000 to $27.02 for the same  period in 2001.
The average price received per barrel of NGLs increased $.95, or 7%, from $13.27
during the six months ended June 30, 2000 to $14.22 for the same period in 2001.
The average price  received per mcf of gas increased  117% from $1.86 during the
six months ended June 30, 2000 to $4.04 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.

Costs and Expenses:

Total costs and expenses increased to $603,950 for the six months ended June 30,
2001 as  compared  to  $557,731  for the same  period in 2000,  an  increase  of
$46,219, or 8%. This increase was primarily due to increases in production costs
and  general  and  administrative  expenses  ("G&A"),  offset  by a  decline  in
depletion.

Production  costs  were  $509,980  for the six months  ended  June 30,  2001 and
$464,779 for the same period in 2000  resulting in a $45,201  increase,  or 10%.
The increase was primarily due to additional well maintenance and workover costs
incurred to stimulate well 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
8% from  $34,139 for the six months  ended June 30, 2000 to $36,760 for the same
period in 2001,  primarily due to a higher  percentage  of the managing  general
partner's  G&A being  allocated  (limited  to 3% of oil and gas  revenues)  as a
result of increased oil and gas revenues and an increase in audit and tax fees.

Depletion  was  $57,210  for the six months  ended June 30,  2001 as compared to
$58,813 for the same period in 2000, a decrease of $1,603,  or 3%. This decrease
was the result of a decline in oil  production of 724 barrels for the six months
ended June 30, 2001 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 13% to $476,179 for the three
months  ended June 30, 2001 as compared to $549,309 for the same period in 2000.
The  decrease  in revenues  resulted  from a decrease  in  production  and lower
average  prices  received  for oil and NGLs,  offset by  higher  average  prices
received for gas. For the three  months ended June 30, 2001,  12,406  barrels of
oil,  5,875 barrels of NGLs and 24,014 mcf of gas were sold, or 22,283 BOEs. For


                                        8

<PAGE>



the three months ended June 30, 2000,  13,188  barrels of oil,  8,087 barrels of
NGLs and 33,092 mcf of gas were sold, or 26,790 BOEs.

The average price received per barrel of oil decreased  $.78, or 3%, from $27.65
for the three  months  ended June 30, 2000 to $26.87 for the three  months ended
June 30, 2001. The average price received per barrel of NGLs decreased $1.77, or
13%,  from $13.84  during the three months ended June 30, 2000 to $12.07 for the
same period in 2001.  The average price received per mcf of gas increased 36% to
$2.99 for the three months ended June 30, 2001 from $2.20 for the same period in
2000.

Costs and Expenses:

Total costs and  expenses  increased to $304,833 for the three months ended June
30, 2001 as compared  to  $290,116  for the same period in 2000,  an increase of
$14,717, or 5%. This increase was primarily due to increases in production costs
and depletion, offset by a decline in G&A.

Production  costs were  $261,190  for the three  months  ended June 30, 2001 and
$245,145 for the same period in 2000 resulting in an increase of $16,045, or 7%.
The increase was primarily due to additional well maintenance and workover costs
incurred to stimulate well production.

During this period,  G&A  decreased  27% from $19,804 for the three months ended
June 30, 2000 to $14,541 for the same period in 2001,  primarily  due to a lower
percentage of the managing general partner's G&A being allocated  (limited to 3%
of oil and gas  revenues)  as a result of  decreased  oil and gas revenues and a
decrease in audit and tax fees.

Depletion  was $29,102 for the three  months  ended June 30, 2001 as compared to
$25,167  for the same  period in 2000,  an  increase  of  $3,935,  or 16%.  This
increase was the result of a reduction in  revisions to proved  reserves  during
the period ended June 30, 2001 as a result of lower commodity prices,  offset by
a decline in oil  production  of 782 barrels for the three months ended June 30,
2001 as compared to the same period in 2000.

Liquidity and Capital Resources

Net Cash Provided by Operating Activities

Net cash  provided by operating  activities  increased  $116,462  during the six
months  ended  June 30,  2001 from the same  period  ended June 30,  2000.  This
increase  was due to an increase of $28,821 in oil and gas sales  receipts and a
reduction  in working  capital of $135,463,  offset by  increases in  production
costs of  $45,201  and G&A  expenses  of  $2,621.  The  increase  in oil and gas
receipts  resulted  from the  increase in gas and NGL prices of $164,517  during
2001, offset by $119,533  resulting from the decline in production and a $16,163
decline  resulting  from lower oil prices  during  2001 as  compared to the same
period in 2000. The increase in production costs was primarily due to additional
well maintenance and workover costs incurred to stimulate well  production.  The
increase in G&A was primarily due to a higher percentage of the managing general
partner's  G&A being  allocated  (limited  to 3% of oil and gas  revenues)  as a
result of increased oil and gas revenues and an increase in audit and tax fees.

Net Cash Used in Investing Activities

The  Partnership's  principal  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.

Net Cash Used in Financing Activities

For the six months ended June 30, 2001, cash  distributions to the partners were
$373,828,  of which $94,450 was distributed to the general partners and $279,378
to the  limited  partners.  For the  same  period  ended  June  30,  2000,  cash
distributions  to the partners were $507,986,  of which $129,953 was distributed
to the general partners and $378,033 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
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.
