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 128% to $550,469 for the three
months ended March 31, 2000 as compared to $241,121 for the same period in 1999.
The increase in revenues  resulted from higher  average  prices  received and an
increase  in  production.  For the three  months  ended March 31,  2000,  13,733
barrels of oil, 8,049 barrels of natural gas liquids  ("NGLs") and 35,379 mcf of
gas were  sold,  or 27,679  barrel of oil  equivalents  ("BOEs").  For the three
months ended March 31, 1999,  14,283  barrels of oil,  6,157 barrels of NGLs and
32,543 mcf of gas were sold, or 25,864 BOEs.

The average price  received per barrel of oil increased  $15.94,  or 136%,  from
$11.72 for the three  months  ended March 31, 1999 to $27.66 for the same period
in 2000. The average price received per barrel of NGLs increased $8.05, or 148%,
from  $5.43 for the three  months  ended  March 31,  1999 to $13.48 for the same
period in 2000.  The average  price  received per mcf of gas  increased 42% from
$1.24  during the three months ended March 31, 1999 to $1.76 for the same period
in 2000.  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, 2000.

The volatility of commodity prices has had, and continues to have, a significant
impact on the Partnership's revenues and operating cash flow and could result in
additional  decreases to the  carrying  value of the  Partnership's  oil and gas
properties.

A gain on  disposition  of assets  of $3,923  during  2000 was  recognized  from
equipment credits received on one fully depleted well.

Costs and Expenses:

Total costs and expenses  decreased to $279,699 for the three months ended March
31,  2000 as compared  to  $296,942  for the same period in 1999,  a decrease of
$17,243,  or 6%. This  decrease  was due to a decrease in  depletion,  offset by
increases in production costs and general and administrative expenses ("G&A").

Production  costs were  $232,950  for the three  months ended March 31, 2000 and
$206,189 for the same period in 1999  resulting in a $26,761  increase,  or 13%.
The increase  was due to higher  production  taxes due to increased  oil and gas
revenues and well maintenance 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,  in  aggregate,  85% from $9,139 for the three months ended March 31,
1999 to $16,889 for the same period in 2000  primarily  due to increased oil and
gas revenues.

Depletion  was $29,860  for the three  months  ended March 31, 2000  compared to
$81,614  for the same  period in 1999,  a  decrease  of  $51,754,  or 63%.  This
decrease was the result of a combination of factors that included an increase in
proved  reserves  during the three  months  ended  March 31,  2000 due to higher
commodity  prices,  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 1999 and a
decline in oil  production  of 550 barrels for the three  months ended March 31,
2000 compared to the same period in 1999.

Liquidity and Capital Resources

Net Cash Provided by Operating Activities:

Net cash provided by operating  activities  increased  $246,880 during the three
months  ended  March 31,  2000 from the same period in 1999.  The  increase  was
primarily attributable to an increase of $289,162 in oil and gas sales receipts,
offset by increases in operating  costs paid of $30,146 and G&A expenses paid of
$12,136.

Cash Provided by (Used in) Investing Activities:

The Partnership's investing activities for the three months ended March 31, 2000
and 1999 were for  expenditures  related to oil and gas  equipment  upgrades  on
active properties.

Proceeds from asset  dispositions of $3,923  recognized  during the three months
ended March 31, 2000 were from equipment  credits received on one fully depleted
well.

Net Cash Used in Financing Activities:

For the three months ended March 31, 2000,  cash  distributions  to the partners
were  $272,131,  of which $68,700 was  distributed  to the general  partners and
$203,431 to the limited partners. For the same period ended March 31, 1999, cash
distributions  to the partners were $31,077,  of which $8,640 was distributed to
the general partners and $22,437 to the limited partners.

Other Items

Year 2000

During 1998, the managing general partner established a "Year 2000" project that
assessed the Partnership's and the managing general partner's internal Year 2000
problem; took remedial actions necessary to minimize the Year 2000 risk exposure
to the managing  general  partner and third  parties;  and,  tested the managing
general partner's systems and processes once remedial actions were taken.

The  managing  general  partner  has  closely   monitored  its  information  and
non-information   technology  systems  since  the  beginning  of  2000  and  has
identified no significant Year 2000 failures or problems.
