                       REMINGTON OIL AND GAS CORPORATION

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

NOTE 1.  ACCOUNTING POLICIES AND BASIS OF PRESENTATION

     Remington Oil and Gas Corporation is an independent oil and gas exploration
and production company incorporated in Delaware. Our oil and gas properties are
located in the shallow water offshore Gulf of Mexico and the onshore Gulf Coast.

     We prepared these financial statements according to the instructions for
Form 10-Q. Therefore, the financial statements do not include all disclosures
required by generally accepted accounting principles. However, we have recorded
all transactions and adjustments necessary to fairly present the financial
statements included in this Form 10-Q/A. The adjustments made are normal and
recurring. The following notes describe only the material changes in accounting
policies, account details or financial statement notes during the first nine
months of 2003. Therefore, please read these financial statements and notes to
the financial statements together with the audited financial statements and
notes to financial statements in our 2002 Form 10-K/A. The income statements for
the three and nine months ended September 30, 2003, cannot necessarily be used
to project results for the full year. We have made certain reclassifications to
prior year financial statements in order to conform to current year
presentations.

NOTE 2.  NEW ACCOUNTING POLICIES

     We adopted Statement of Financial Accounting Standards No. 143, "Accounting
for Asset Retirement Obligations," effective January 1, 2003. The statement
requires that we estimate the fair value for our asset retirement obligations
(dismantlement and abandonment of oil and gas wells and offshore platforms) in
the periods the assets are first placed in service. We then adjust the current
estimated obligation for estimated inflation and market risk contingencies to
the projected settlement date of the liability. The result is then discounted to
a present value from the projected settlement date to the date the asset was
first placed in service. We recorded the present value of the asset retirement
obligation as an additional property cost and as an asset retirement liability.
A combination of the amortization of the additional property cost (using the
unit of production method) and the accretion of the discounted liability is
recorded as a periodic expense in our income statement.

     Prior to this adoption, we accrued an estimated dismantlement, restoration
and abandonment liability using the unit of production method over the life of a
property and included the accrued amount in depreciation, depletion and
amortization expense. The total accrued liability ($5.5 million) was reflected
as additional accumulated depreciation, depletion and amortization of oil and
gas properties on our balance sheet.

     In conformity with the new statement we recorded the cumulative effect of
this accounting change as of January 1, 2003 as if we had used this method in
the prior years. At January 1, 2003, we increased our oil and gas properties by
$9.0 million, recorded $11.8 million as an Asset Retirement Obligation liability
and reduced our accumulated depreciation by $2.8 million ($5.5 million accrued
dismantlement in prior years less accumulated depreciation, depletion and
amortization of $2.7 million on the increased property costs). The

adoption of the new standard had no material effect on our net income. The
following table reflects the reconciliation of the asset retirement obligations
during the first nine months of 2003.

     SFAS No. 141, "Business Combinations" and SFAS No. 142, "Goodwill and
Intangible Assets" became effective for us on July 1, 2001, and January 1, 2002,
respectively. SFAS No. 141 requires all business combinations initiated after
June 30, 2001, to be accounted for using the purchase method. Additionally, SFAS
No. 141 requires companies to disaggregate and report separately from goodwill
certain intangible assets. SFAS No. 142 establishes new guidelines for
accounting for goodwill and other intangible assets. Under SFAS No. 142,
goodwill and certain other intangible assets are not amortized, but rather are
reviewed annually for impairment. The appropriate application of SFAS Nos. 141
and 142 to oil and gas mineral rights held under lease and other contractual
arrangements representing the right to extract such reserves is unclear.
Depending on how the accounting and disclosure literature is clarified, these
oil and gas mineral rights held under lease and other contractual arrangements
representing the right to extract such reserves for both undeveloped and
developed leaseholds may be classified separately from oil and gas properties,
as intangible assets on our balance sheets. Additional disclosures required by
SFAS Nos. 141 and 142 would be included in the notes to financial statements.
Historically, we, like many other oil and gas companies, have included these oil
and gas mineral rights held under lease and other contractual arrangements
representing the right to extract such reserves as part of the oil and gas
properties, even after SFAS Nos. 141 and 142 and became effective.

     This interpretation of SFAS Nos. 141 and 142 would affect only our balance
sheet classification of oil and gas leaseholds. Our results of operations and
cash flows would not be affected, since these oil and gas mineral rights held
under lease and other contractual arrangements representing the right to extract
such reserves would continue to be amortized in accordance with accounting rules
for oil and gas companies provided in SFAS No. 19, "Financial Accounting and
Reporting by Oil and Gas Producing Companies."

     At September 30, 2003, we had net leaseholds cost of approximately $37.2
million. If we applied the interpretation currently being deliberated, this
classification would require us to make the disclosures set forth under SFAS No.
142 related to these interests. We will continue to classify our oil and gas
leaseholds as oil and gas properties until further guidance is provided.

NOTE 5.  NOTES PAYABLE

     Effective May 1, 2003, we agreed with our lenders to increase our borrowing
base from $75.0 million to $100.0 million and to extend the maturity date of the
loan facility from May 3, 2004, to May 3, 2006. As of September 30, 2003, we had
$37.4 million borrowed under the facility. The banks review the borrowing base
semi-annually and may decrease or propose an increase to the borrowing base
relative to a redetermined estimate of proved oil and gas reserves. Our oil and
gas properties are pledged as collateral for the line of credit. Additionally,
we have agreed not to pay dividends.

NOTE 6.  COMMITMENTS AND CONTINGENCIES

     For the period July 1, 2003, through December 31, 2003, we have physical

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

     The following discussion will assist in the understanding of our financial
position and results of operations. Our discussion contains both historical and
forward-looking information. We assess the risks and uncertainties about our
business, long-term strategy, and financial condition before we make any
forward-looking statements, but we cannot guarantee that our assessment is
accurate or that our goals and projections can or will be met. Statements
concerning results of future exploration, exploitation, development, and
acquisition expenditures as well as revenue, expense, and reserve levels are
forward-looking statements. We make assumptions about commodity prices, drilling
results, production costs, administrative expenses, and interest costs that we
believe are reasonable based on currently available information.

     This discussion is primarily an update to the Management's Discussion and
Analysis of Financial Condition and Results of Operations included in the 2002
Form 10-K/A. We recommend that you read the information below in conjunction
with the financial statements, the related notes to financial statements, and
our Form 10-K/A for the year ended December 31, 2002.

     Our long-term strategy is to increase our oil and gas reserves and
production while keeping our finding and development costs and operating costs
competitive with our industry peers. We will implement this strategy through
drilling exploratory and development wells from our inventory of available
prospects that we have evaluated for geologic and mechanical risk and future
reserve or resource potential. Our drilling program will contain some high
risk/high reserve potential opportunities as well as some lower risk/lower
reserve potential opportunities, in order to achieve a balanced program of
reserve and production growth. Success of this strategy is contingent on various
risk factors, as discussed in our filings with the Securities and Exchange
Commission.

     On September 30, 2003, our current assets exceeded our current liabilities
by $26.1 million. Our current ratio was 1.69 to 1.

     Net cash flow provided by operations increased by $36.1 million, or 68%,
primarily because of higher oil and gas revenues during the nine months of 2003
compared to 2002. Gas sales increased by $54.9 million, or 132% because
production increased by 27% and average prices increased by 83%. In addition,
oil sales increased by $7.3 million, or 23%, primarily because oil prices
increased by 24%.

     During the first nine months of 2003, our capital expenditures totaled
$89.1 million of which $82.7 million, or 93%, was spent in the Gulf of Mexico
where we incurred costs to drill and complete wells and upgrade and complete
platforms and facilities. We anticipate total capital expenditures for 2003 to
be approximately $110.0 million, which is a 14% increase over the original
capital and exploration budget of $96.1 million. The increase is due to
additional development costs anticipated as a result of successful exploration
drilling. We expect that our cash, estimated future cash flow from operations,
and available bank line of credit will be adequate to fund these expenditures
for the remainder of 2003.

                                        9


     If our exploratory drilling results in significant new discoveries, we will
have to expend additional capital for the completion, development, and potential
additional opportunities generated by our success. We believe that, because of
the additional reserves resulting from the exploratory success and our record of
reserve growth in recent years, we will be able to acquire sufficient additional
capital through additional bank financing and/or offerings of debt or equity
securities.

     Effective May 1, 2003, we agreed with our lenders to increase our borrowing
base from $75.0 million to $100.0 million and to extend the maturity date of the
loan facility from May 3, 2004, to May 3, 2006. As of September 30, 2003, we had
$37.4 million borrowed under the facility. The banks review the borrowing base
semi-annually and may decrease or propose an increase to the borrowing base
relative to a redetermined estimate of proved oil and gas reserves. Our oil and
gas properties are pledged as collateral for the line of credit. Additionally,
we have agreed not to pay dividends.

     On June 19, 2003, we filed a shelf registration statement to issue up to
$200 million of common stock, debt securities, preferred stock, and/or warrants.
We expect the registration statement to become effective during the fourth
quarter of this year.

RESULTS OF OPERATIONS

     We recorded net income for the three months ended September 30, 2003, of
$10.1 million or $0.38 basic income per share and $0.36 diluted income per share
compared to $4.0 million or $0.15 basic income per share and $0.14 diluted
income per share for the three months ended September 30, 2002. For the first
nine months of 2003 we recorded net income of $34.0 million or $1.28 basic
income per share and $1.22 diluted income per share compared to $10.5 million or
$0.42 basic income per share and $0.39 diluted income per share for the first
nine months of 2002. Net income for the three and nine months ended September
30, 2003, was higher than in the prior year primarily because of increased oil
and gas revenues, partially offset by higher exploration expenses and a $4.1
million gain from the sale of certain South Texas properties in 2002. The
following table reflects the increase or decrease in oil and gas sales revenue
due to the changes in prices and volumes.

     Oil sales revenue for the third quarter of 2003 compared to the same period
in 2002 decreased by $515,000, or 4%, primarily because of lower oil production
partially offset by higher average prices. Oil

                                        10


production from new properties added 70,000 barrels of production during the
third quarter of 2003 which was more than offset by natural depletion from
existing properties. Average prices increased from $25.91 during the third
quarter of 2002 to $28.18 during the third quarter of 2003.

     Oil sales revenue for the first nine months of 2003 increased by $7.3
million, or 23%, compared to the same period in 2002 primarily because average
oil prices increased by $5.77, or 24%, partially offset by slightly lower
production. Total oil production decreased by a net 10,000 barrels, or 1%.
Production from new wells totaling 135,000 barrels partially offset the overall
decreased from natural depletion of existing producing properties and the sale
of certain properties in South Texas in 2002. Average prices increased from
$23.69 during the first nine months of 2002 to $29.45 during the first nine
months of 2003, which increased oil revenues by $7.6 million.

     Gas sales revenue for the three months ended September 30, 2003, compared
to the same period in 2002 increased by $21.4 million, or 163% because of
increases in both total production and average prices. During the three months
ended September 30, 2003, production from new wells totaled 3.8 Bcf, partially
offset by natural depletion from producing properties and the sale of certain
South Texas properties in 2002. Average prices increased from $3.26 during the
three months ended September 30, 2002 to $5.00 during the same three months of
2003, which increased gas revenues by $7.0 million.

     Gas sales revenue for the first nine of 2003 increased by $54.9 million, or
132%, compared to the first nine months of 2002 because of increases in both
total production and average prices. During 2003, production from new wells
totaled 7.2 Bcf, partially offset by natural depletion from producing properties
and the sale of certain South Texas properties in 2002. Average prices increased
from $3.04 during the first nine months of 2002 to $5.58 during the first nine
months of 2003, which increased gas revenues by $34.6 million.

     Other income decreased primarily because we realized a $4.1 million gain
from the sale of properties in South Texas in April 2002.

     The following table presents certain expense items per Mcf equivalent
(Mcfe) of production. (Barrels of oil are converted to Mcfe at a ratio of one

     Operating costs and expenses for the third quarter of 2003 compared to the
third quarter of 2002 increased by $845,000, or 19%, and for the first nine
months of 2003 compared to 2002 increased by $2.8 million, or 23% primarily
because of new operated properties in the Gulf of Mexico. In addition, increases
in delay rental expense for unproved properties, insurance rates, and repairs
expense on existing properties also increased operating costs and expenses. The
primary reason for the decrease in the rate per Mcfe occurred because of the 36%
increase in total Mcfe production.

     Exploration expense, including dry hole costs and property impairment
costs, increased by $5.0 million during the third quarter of 2003 and by $9.8
million during the first nine months of 2003. The expense increased primarily
because of increased dry hole expense. Dry hole expense for 2003 includes 8
wells in the Gulf of Mexico, one well in Mississippi and one well in South Texas
for a total cost of $19.7 million compared to $9.8 million dry hole expense in
2002.

                                        11


     Depreciation, depletion, and amortization expense increased by $5.7 million
during the third quarter of 2003 and by $9.4 million during the first nine
months of 2003 compared to the same period in the prior year primarily because
of an increase in the number of producing properties.

     General and administrative expenses have increased slightly due to employee
related expense. Included in general and administrative expenses is stock based
compensation expense which includes the amortized compensation cost related to
the contingent stock grant and the directors fees paid in common stock.

     Interest and financing expenses increased slightly during the third quarter
of 2003 compared to the third quarter of 2002 because of higher bank debt during
the quarter partially offset by lower rates. During the first nine months of
2003 interest and financing expenses decreased by 23% because of lower average
bank debt and lower interest rates as compared to the nine month period of 2002.
In March 2002, we issued 3.0 million shares of common stock at $18.50 per share.
We used $44.0 million of the net proceeds to reduce outstanding bank debt from
$71.0 million to $27.0 million.

     Income tax expense increased for the three and nine months ended September
30, 2003 because of the increase in income before taxes.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

  INTEREST RATE RISK

     Our revolving bank line of credit is sensitive to changes in interest
rates. At September 30, 2003, the unpaid principal balance under the line was
$37.4 million which approximates its fair value. The interest rate on this debt
is based on a premium of 150 to 225 basis points over the London Interbank
Offered Rate ("Libor"). The rate is reset periodically, usually every three
months. If on September 30, 2003, Libor changed by one full percentage point
(100 basis points) the fair value of our revolving debt would change by
approximately $93,000. We have not entered into any interest rate hedging
contracts.

  COMMODITY PRICE RISK

     A vast majority of our production is sold on the spot markets. Accordingly,
we are at risk for the volatility in the commodity prices inherent in the oil
and gas industry.

     Occasionally we sell forward portions of our production under physical
delivery contracts that by their terms cannot be settled in cash or other
financial instruments. Such contracts are not subject to the provisions of
Statement of Financial Accounting Standards No. 133, "Accounting for Derivative
Instruments and Hedging Activities." Accordingly, we do not provide sensitivity
analysis for such contracts. For the period July 1, 2003, through December 31,
2003, we have physical delivery contracts in place to sell 21,500 MMBtu of gas
per day and 1,200 barrels of oil per day at the following prices:



                                                                PRICE PER

ITEM 4. CONTROLS AND PROCEDURES

     As of the end of the period covered by this report, our management,
including our Chief Executive Officer and our Principal Financial Officer,
evaluated the effectiveness of our disclosure controls and procedures as defined
in Exchange Act Rule 13a-15(e). Based on that evaluation, our management,
including the Chief Executive Officer and the Principal Financial Officer,
concluded that our disclosure controls and procedures were effective as of the
end of the period covered by this report. Further, during the period covered by
this report, there was no significant change in internal controls over financial
reporting that has materially affected, or is reasonably likely to materially
affect, our internal control over financial reporting.
