CComparison of the Quarters Ending June 30 2003 and 2002

The Company recognized $1,436,848 in oil and gas revenues from its Kansas
Properties and the Swan Creek Field during the second quarter of 2003 compared
to $1,233,473 in the second quarter of 2002. The increase in revenues was due to
an increase in price from oil and gas sales. Oil prices averaged $26.47 per
barrel in 2003 as compared to $23.73 in 2002. Gas prices averaged $5.00 per Mcf
in 2003 as compared to $3.30 for 2002. The Swan Creek Field produced 95,389 Mcf
and 192,960 Mcf in the second quarter of 2003 and 2002, respectively. This
decrease was due to natural declines in production which could not be offset as
the Company did not have the funds to continue drilling new wells, due to it's
dispute with it's primary lender, Bank One NA. The decrease in pipeline
transportation revenues is directly related to the decrease in gas volumes.

The Company realized a net loss attributable to common shareholders of $786,802
(($.07) per share of common stock) during the second quarter of 2003 compared to
a net loss in the second quarter of 2002 to common shareholders of $984,139
(($.09) per share of common stock)
