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  12% to $955,101 for the six
months  ended June 30, 2001 as compared to $856,273 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  received
for oil.  For the six months ended June 30, 2001,  19,403 barrels of oil, 10,669

                                        7





barrels of natural  gas  liquids  ("NGLs")  and 54,393 mcf of gas were sold,  or
39,138  barrel of oil  equivalents  ("BOEs").  For the six months ended June 30,
2000,  21,638 barrels of oil,  12,002 barrels of NGLs and 45,739 mcf of gas were
sold, or 41,263 BOEs.

The average price received per barrel of oil decreased  $.22, or 1%, from $27.64
for the six months  ended June 30,  2000 to $27.42 for the same  period in 2001.
The average  price  received per barrel of NGLs  increased  $2.26,  or 16%, from
$13.72  during the six months  ended June 30, 2000 to $15.98 for the same period
in 2001.  The average price  received per mcf of gas  increased  126% from $2.05
during the six months  ended June 30, 2000 to $4.64 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 decreased to $522,597 for the six months ended June 30,
2001 as compared to $554,066 for the same period in 2000, a decrease of $31,469,
or 6%. This  decrease was due to declines in  depletion  and  production  costs,
offset by an increase in general and administrative expenses ("G&A").

Production  costs  were  $433,153  for the six months  ended  June 30,  2001 and
$448,472  for the same period in 2000  resulting in a $15,319  decrease,  or 3%.
This decrease was due to lower well maintenance and workover costs.

G&A's  components are independent  accounting and engineering  fees and managing
general partner personnel and operating costs. During this period, G&A increased
12% from  $25,688 for the six months ended June 30, 2000 to $28,653 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  $60,791  for the six months  ended June 30,  2001 as compared to
$79,906 for the same period in 2000, a decline of $19,115, or 24%. This decrease
was due to upward revisions in proved reserves on three significant wells during
the period ended June 30, 2001 and a decrease in oil production of 2,235 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 4% to $422,897 for the three
months  ended June 30, 2001 as compared to $439,126 for the same period in 2000.
The  decrease  in revenues  resulted  from a decrease  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,  9,459  barrels of oil,
5,538 barrels of NGLs and 25,535 mcf of gas were sold,  or 19,253 BOEs.  For the


                                        8





three months ended June 30, 2000,  10,480  barrels of oil, 6,550 barrels of NGLs
and 23,989 mcf of gas were sold, or 21,028 BOEs.

The average price received per barrel of oil decreased  $.86, or 3%, from $27.72
for the three  months ended June 30, 2000 to $26.86 for the same period in 2001.
The average price received per barrel of NGLs increased $.24, or 2%, from $13.79
during the three  months  ended June 30,  2000 to $14.03 for the same  period in
2001.  The average price received per mcf of gas increased 47% from $2.43 during
the three months ended June 30, 2000 to $3.57 for the same period in 2001.

Costs and Expenses:

Total costs and  expenses  decreased to $258,243 for the three months ended June
30,  2001 as compared  to  $281,440  for the same period in 2000,  a decrease of
$23,197, or 8%. This decrease was due to declines in production costs, depletion
and G&A.

Production  costs were  $215,988  for the three  months  ended June 30, 2001 and
$231,517  for the same period in 2000  resulting in a $15,529  decrease,  or 7%.
This decrease was primarily due to lower workover and well maintenance costs.

During this  period,  G&A  decreased  4% from $13,174 for the three months ended
June 30,  2000 to  $12,687  for the same  period  in  2001,  primarily  due to a
decrease in audit and tax fees

Depletion  was $29,568 for the three  months  ended June 30, 2001 as compared to
$36,749 for the same period in 2000, a decrease of $7,181, or 20%. This decrease
was primarily due to upward  revisions to proved  reserves on three  significant
wells during the period ended June 30, 2001 and a decrease in oil  production of
1,021  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  $222,080  during the six
months  ended  June 30,  2001 from the same  period  ended June 30,  2000.  This
increase  was  due to an  increase  of  $99,580  in oil  and  gas  receipts  and
reductions  of $110,146 in working  capital  and  $15,319 in  production  costs,
offset by an increase in G&A  expenses  of $2,965.  The  increase in oil and gas
receipts  resulted  from the  increase in gas and NGL prices of $145,824  during
2001,  offset  by a  decline  of  $42,415  in  production  and a $3,829  decline
resulting  from lower oil prices as  compared  to the same  period in 2000.  The
decrease in production  costs was primarily  due to lower well  maintenance  and
workover costs. 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 investing activities during the six months ended June 30, 2001
and  2000  were  related  to  expenditures  for  equipment  upgrades  on  active
properties.

                                        9





Proceeds from  disposition  of assets of $311  recognized  during the six months
ended  June 30,  2001  were  due to  equipment  credits  received  on an  active
property.

Net Cash Used in Financing Activities

For the six months ended June 30, 2001, cash  distributions to the partners were
$311,278,  of which $3,113 was  distributed to the managing  general partner and
$308,165 to the limited partners.  For the same period ended June 30, 2000, cash
distributions to the partners were $351,708,  of which $3,517 was distributed to
the managing general partner and $348,191 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.
