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

Results of Operations

Revenues:

The Partnership's  oil and gas revenues  increased 19% to $634,643 for the three
months ended March 31, 2001 as compared to $533,060 for the same period in 2000.
The increase in revenues resulted from higher average prices received, offset by
a decline in  production.  For the three  months  ended March 31,  2001,  13,629
barrels of oil, 6,391 barrels of natural gas liquids  ("NGLs") and 33,550 mcf of
gas were  sold,  or 25,612  barrel of oil  equivalents  ("BOEs").  For the three
months ended March 31, 2000,  13,571  barrels of oil,  8,220 barrels of NGLs and
35,071 mcf of gas were sold, or 27,636 BOEs.

The average price received per barrel of oil decreased  $.45, or 2%, from $27.61
for the three months ended March 31, 2000 to $27.16 for the same period in 2001.
The average  price  received per barrel of NGLs  increased  $3.50,  or 28%, from
$12.70 for the three  months  ended March 31, 2000 to $16.20 for the same period
in 2001.  The average price  received per mcf of gas  increased  212% from $1.54
during the three  months  ended  March 31,  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 three
months ended March 31, 2001.

Costs and Expenses:

Total costs and expenses  increased to $299,117 for the three months ended March
31, 2001 as compared  to  $267,615  for the same period in 2000,  an increase of
$31,502,  or 12%.  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  $248,790  for the three  months ended March 31, 2001 and
$219,634 for the same period in 2000  resulting in a $29,156  increase,  or 13%.
The increase was primarily due to additional well maintenance  costs incurred to
stimulate well production and higher production taxes associated with higher oil
and gas prices.

G&A's  components are independent  accounting and engineering  fees and managing
general partner  personnel and  administrative  costs.  During this period,  G&A
increased  55% from $14,335 for the three months ended March 31, 2000 to $22,219
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 the
accrual for tax preparation fees.

Depletion  was $28,108 for the three  months ended March 31, 2001 as compared to
$33,646 for the same period in 2000, a decrease of $5,538, or 16%. This decrease
was the result of positive  revisions to proved reserves during the three months
ended March 31, 2001 as a result of higher commodity prices.

Liquidity and Capital Resources

Net Cash Provided by Operating Activities

Net cash provided by operating  activities  increased  $63,503  during the three
months  ended March 31, 2001 from the same period in 2000.  The increase was due
to an increase of $102,540 in oil and gas sales receipts, offset by increases in
production  costs of $29,156,  G&A  expenses  of $7,884 and  working  capital of
$1,997.  The  increase in oil and gas  receipts  resulted  from the  increase in
commodity prices during 2001 which contributed an additional $137,887 to oil and
gas receipts,  offset by $35,347 resulting from the decline in production during
2001 as compared to the same period in 2000.  The increase in  production  costs
was primarily due to additional  well  maintenance  costs  incurred to stimulate
well production and  increased production  taxes associated  with higher oil and

gas prices.  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 the
accrual for tax preparation fees.

Net Cash Used in Investing Activities

The Partnership's  principal investing  activities during the three months ended
March 31, 2001 and 2000 were for  expenditures  related to oil and gas equipment
upgrades on active properties.

Net Cash Used in Financing Activities

For the three months ended March 31, 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 March 31, 2000, cash
distributions to the partners were $215,712, of which $54,767 was distributed to
the general partners and $160,945 to the limited partners.

Proposal to acquire partnerships

On April  17,  2001,  Pioneer  Natural  Resources  Company  ("Pioneer")  filed a
preliminary  proxy   statement/prospectus   with  the  Securities  and  Exchange
Commission  proposing an agreement  and plan of merger  among  Pioneer,  Pioneer
Natural  Resources  USA, Inc.  ("Pioneer  USA"),  a wholly- owned  subsidiary of
Pioneer,  and the limited partners of 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,  and the
partnership  interests of each such partnership will be converted into the right
to receive cash and Pioneer  common  stock.  Pioneer USA is the sole or managing
general partner of the  partnerships.  The Partnership is one of the 46 Parker &
Parsley limited  partnerships  being requested 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,  the majority  approval of the limited
partnership  interests in each  partnership and the resolution of Securities and
Exchange  Commission  review  comments.  No  solicitation  will  be  made  using
preliminary materials.
