Net income for the second quarter of 2003 increased by $6.0 million, or 96%, to
$12.3 million, or $0.46 basic income per share and $0.44 diluted income per
share compared to second quarter of 2002. Net income for the first six months of
2003 increased by $17.4 million, or 268%, to $24.0 million or $0.91 basic income
per share and $0.86 diluted income per share compared to the first six months of
2002. Net income in 2003 increased primarily due to increased production and
commodity prices partially offset by higher exploration expenses and higher
operating costs due to new producing properties.

Net cash flow provided by operations increased by $11.5 million to $38.2 million
during the second quarter and by $33.6 million to $63.2 million for the first
half of 2003 compared to the same periods in the prior year. Net cash flow
provided by operations before changes in working capital for the second quarter
of 2003 increased by $16.8 million, or 80%, compared to the second quarter of
2002. Net cash flow provided by operations before changes in working capital for
the first six months of 2003 increased by $38.5 million, or 110%, compared to
the first six months of 2002. The following table reconciles net cash flow
provided by operations to net cash flow provided by operations before changes in
working capital accounts.

* Includes the increases or decreases in accounts receivable, prepaid expenses
and other current assets, and accounts payable and accrued liabilities.

Total production increased by 1.0 Bcfe, or 13%, to 8.5 Bcfe during the second
quarter of 2003. Total production for the first half of 2003 increased by 1.1
Bcfe, or 7%, to 15.6 Bcfe. The increase is primarily the result of production
from new properties in the Gulf of Mexico. Average oil prices increased by 13%
to $28.15 per barrel during the second quarter of 2003 and increased by 35% to
$30.09 per barrel during the first six months of 2003. Average gas prices
increased by 71% to $5.67 per Mcf during the second quarter of 2003 and
increased by 102% to $5.97 per Mcf during the first six months of 2003.

Operating costs (which include direct operating expenses, transportation,
severance taxes, and delay rentals) for the three-month periods were $5.3
million ($0.62/Mcfe) during 2003 versus $4.5 million ($0.59/Mcfe) during 2002.
For the six-month periods operating costs were $9.7 million ($0.62 per Mcfe)
during 2003 and $7.7 million ($0.53 per Mcfe) in 2002. Operating costs increased
primarily due to new operated properties. In addition, increases in delay rental
expense for unproved properties, insurance rates, and repairs expense on
existing properties increased operating costs and expenses.

Exploration expense increased by $1.4 million during the second quarter of 2003
and by $4.8 million during the first six months of 2003 primarily because of
increased dry hole expense. Dry hole expense for 2003 includes 6 wells in the
Gulf of Mexico, one well in Mississippi and one well in South Texas for a total
cost of $12.3 million compared to $8.3 million dry hole expense in 2002. During
the second quarter of 2003 dry hole expense totaled $5.8 million compared to
$4.3 million during the second quarter of 2002.

Depreciation, depletion, and amortization expense increased from $10.3 million
($1.35 per Mcfe) during the second quarter of 2002 to $12.8 million ($1.50 per
Mcfe) during the second quarter of 2003 and from $19.8 million ($1.36 per Mcfe)
during the first six months of 2002 to $23.5 million ($1.51 per Mcfe) during the
first six months of 2003. The increase in the rate is the result of the increase
in production from properties with higher property costs per Mcfe.

General and administrative expenses have increased slightly due to employee
related expense, but have remained at $0.26 per Mcfe for the three months ended
June 30, 2003 and 2002 and at $0.25 per Mcfe for the six months ended June 30,
2003 and 2002. Included in general and administrative expenses is non-cash stock
based compensation expense which is $0.04 and $0.05 per Mcfe during the three
months ended June 30, 2003 and 2002, respectively and $0.05 and $0.06 per Mcfe
for the six months ended June 30, 2003 and 2002, respectively.

                                     -more-

Interest and financing expenses increased slightly during the second quarter of
2003 compared to the




second quarter of 2002, but decreased by 31% because of lower average bank debt
during the first six months of 2003 compared to 2002. On a per Mcfe basis
interest and financing costs are unchanged at $0.06 per Mcfe during the second
quarters of 2003 and 2002, and are 36% lower in the first six months of 2003
compared to the same period in 2002.

In this report we have combined into one line item of general and administrative
expense what we previously reported separately as stock based compensation and
other general and administrative expenses. Further, in previous reports,
production taxes were treated as a reduction in revenue. In this report
production taxes have been reclassified to operating expenses for all periods
presented.

James A. Watt, President and Chief Executive Officer said, "Our excellent
financial results for the quarter were driven by increased production volumes
and higher commodity prices. On a Mcfe basis our costs were within guidance
provided to the marketplace. We intend to maintain our high activity level for
the remainder of the year investing our cash flow in new opportunities for our
shareholders."

Statements concerning future revenues and expenses, results of exploration,
exploitation, development and acquisition expenditures, and reserve levels are
forward-looking statements. These statements are based on assumptions concerning
commodity prices, drilling results and production, administrative and interest
costs that management believes are reasonable based on currently available
information; however, management's assumptions and the Company's future
performance are subject to a wide range of business risks and there is no
assurance that these goals and projections can or will be met. Further
information is available in the Company's filings with the Securities and
Exchange Commission, which are incorporated by this reference.
