NOTE 1 - BASIS OF PRESENTATION

The  Unaudited  Pro Forma Balance Sheet as of September 30, 2006 is presented as
if the  divestitures had occurred on September 30, 2006. The Unaudited Pro Forma
Statements of Operations  for the years ended  December 31, 2005,  2004 and 2003
and for the  nine  months  ended  September  30,  2006 are  presented  as if the
divestitures had occurred on January 1, 2003.

The Partnership  follows the successful efforts method of accounting under which
proceeds from the sale of oil and gas  properties  are accounted for as gains or
losses net of their carrying costs and transaction expenses.

The Pro Forma  Statements of Operations  for the years ended  December 31, 2005,
2004 and 2003, and for the nine months ended  September 30, 2006, do not reflect
the estimated gain on the  divestitures.  Assuming the sales closed on September
30, 2006, an estimated  non-recurring gain of $3,165,628 for the October auction
and an estimated  non-recurring  gain of $315,661 for the December auction would
have been recognized.

NOTE 2 - PRO FORMA ADJUSTMENTS

(a)   Reflects net sales proceeds from the October auction of $3,285,062 for the
      P-1  Partnership  and the  reversal of the Net Profits  Interests  and the
      asset retirement obligations associated with the properties sold.

(b)   Reflects net sales proceeds from the December  auction of $322,460 for the
      P-1  Partnership  and the  reversal of the Net Profits  Interests  and the
      asset retirement obligations associated with the properties sold.

(c)   Oil and gas sales,  lease  operating  expenses,  and production  taxes are
      adjusted to reflect the reversal of revenues and expenses  attributable to
      the sold  properties.  Depletion of Net Profits  Interests is adjusted for
      the reductions in depletion of Net Profits  Interests and asset retirement
      obligation  accretion expenses  attributable to the properties sold. These
      adjustments  were not necessary in the  Unaudited Pro Forma  Statements of
      Operations  for the nine months ended  September 30, 2006 as the operating
      results of the sold  properties  were already  reflected  as  discontinued
      operations.
