</Table>

Total revenues, net income and cash flow from operations before changes in
working capital increased during the first quarter of 2003 primarily because of
higher average oil and gas prices. Production was 7.1 Bcfe, a 2% increase over
the first quarter of 2002, and a sequential 13% increase over the fourth quarter
of 2002. Gas sales revenue increased by $16.4 million, or 134%, and oil sales
revenue increased by $6.5 million, or 93%. Net income increased by $11.4 million
and cash flow provided by operations before changes in working capital increased
by $21.7 million. Average gas prices increased from $2.57 per Mcf in 2002 to
$6.35 per Mcf in 2003. Average oil prices increased from $19.15 per barrel to
$31.87 per barrel. No hedges or forward sales were in place in the first
quarter. Total oil production increased by 16% primarily from new properties in
the Gulf of Mexico, and total gas production decreased by 5% because of property
sales in South Texas in 2002 partially offset by increased production from the
Gulf of Mexico.

Operating costs and expenses were $0.60 per Mcfe compared to $0.45 per Mcfe in
2002 partially due to a higher proportion of more costly oil production.
Depreciation, depletion, and amortization increased from $1.38 per Mcfe to $1.52
per Mcfe in 2003 reflecting an increase in our rate due to increased production
from new higher cost properties. General and administrative expenses did not
change at $0.18 per Mcfe for each of the quarters ending March 31, 2003 and
2002. Interest and financing costs decreased to $0.06 per Mcfe from $0.12 per
Mcfe, or by 52%, due to lower average rates and a decrease in the average debt
outstanding.




                                    - more -

Deferred income tax expense increased by $6.2 million because of higher income
before taxes in the first quarter of 2003 compared to the first quarter of 2002.
Exploration expenses increased to $7.1 MM from $3.7 MM primarily because of dry
hole costs for wells drilled in the Gulf of Mexico, reflecting a much more
active drilling program in the first quarter of 2003.

The adoption of Statement of Financial Accounting Standards No. 143, "Accounting
for Asset Retirement Obligations," had no material effect on our first quarter
net income. Our prior estimates of abandonment liabilities were in line with the
estimation methodology required under FASB 143.

James A. Watt, President and Chief Executive Officer said, "First quarter
operating margins were excellent. We expect DD&A, LOE, G&A and interest costs to
be within guidance provided to the marketplace allowing for continued excellent
margins, even in a somewhat lower commodity price environment. Production is on
track for 35-37 Bcfe for the year providing cash flow to continue growing our
reserve base primarily through exploration drilling."

Remington Oil and Gas Corporation is an independent oil and gas exploration and
production company headquartered in Dallas, Texas, with operations concentrating
in the onshore and offshore regions of the Gulf Coast.

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.
