NOTE 1 - BASIS OF PRESENTATION

The consolidated financial statements of Endeavour International Corporation,
formerly Continental Southern Resources, Inc., a Nevada corporation, included
herein have been prepared, without audit, pursuant to the rules and regulations
of the Securities and Exchange Commission ("SEC"), and, accordingly, certain
information normally included in financial statements prepared in accordance
with accounting principles generally accepted in the United States has been
condensed or omitted. As used in these Notes to Condensed Consolidated
Financial Statements, the terms the "Company", "Endeavour", "we", "us", "our"
and similar terms refer to Endeavour International Corporation and, unless the
context indicates otherwise, its consolidated subsidiaries.

The financial statements herein reflect all normal recurring adjustments that,
in the opinion of management, are necessary for a fair presentation. Certain
amounts for prior periods have been reclassified to conform to the current
presentation. In preparing financial statements, management makes informed
judgments and estimates that affect the reported amounts of assets and
liabilities as of the date of the financial statements and affect the reported
amounts of revenues and expenses during the reporting period. Changes in facts
and circumstances may result in revised estimates and actual results may differ
from these estimates.

The accompanying consolidated financial statements of Endeavour should be read
in conjunction with the consolidated financial statements and notes included in
our Annual Report on Form 10-KSB for the year ended December 31, 2003 and Form
8-K filed on July 12, 2004. As discussed in Note 2, the Company changed its
method of accounting for oil and gas properties in the second quarter of 2004.
The Form 8-K filed on July 12, 2004 provides restated financial information for
the years ended December 31, 2003 and 2002 and the quarters ended March 31,
2004 and 2003 under this new method of accounting.

In February 2004, the Company significantly restructured its business in a
series of simultaneous transactions (the Offering, Merger and Restructuring)
and changed its name to Endeavour International Corporation (see Note 3). In
June 2004, our common stock began trading on the American Stock Exchange under
the symbol "END." Prior to June 2004, our common stock traded on the OTC
Bulletin Board.


NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES

CHANGE IN METHOD OF ACCOUNTING FOR OIL AND GAS PROPERTIES

Effective April 1, 2004, we changed our method of accounting for oil and gas
properties from the successful efforts method to the full cost method. We
believe that the full cost method of accounting is more appropriate for
Endeavour in light of the significant changes in our operations that have
recently occurred. We believe capitalization of seismic and other

                                  (UNAUDITED)


exploration technology expenditures as well as the cost of all exploratory
wells recognizes the value these expenditures add to the program of an
exploration focused company like Endeavour. Amortization of these costs over
the life of the discovered reserves provides a more appropriate method of
matching revenues and expenses related to our exploration strategy. Our
technical strategy is founded on a philosophy that regional petroleum systems
analyses improve competitive advantage, reduce exploration risk and optimize
value creation. Regional petroleum systems analysis has been successfully
employed by our new management and technical team in their past experiences to
identify and commercialize reserves in basins worldwide.

On February 26, 2004, we completed a series of transactions that significantly
transformed the nature and scope of our business. These changes include:

     o   a new management team;
     o   a new business strategy of exploration, exploitation and acquisition
         that will be focused on the North Sea;
     o   the acquisition of NSNV, Inc. which possessed the seismic data and
         management team that will be central to the Company's new strategy;
         and
     o   a restructuring which resulted in the sale of substantially all
         interests in U.S. oil and gas properties.

Prior to February 2004, the Company had no technical exploration and production
staff, and the Company did not have any production until the fourth quarter of
2003. The only producing property, which had minimal production, was sold in
the February 2004 restructuring.

We believe that the full cost method of accounting will more accurately reflect
the results of our future operations. The full cost method of accounting is
used by many independent oil and gas companies and its use will allow investors
to better assess the performance of the Company.

Under the full cost method, all acquisition, exploration and development costs,
including certain directly related employee costs and a portion of interest
expense, incurred for the purpose of finding oil and gas are capitalized. These
capitalized costs are accumulated in pools on a country-by-country basis.
Capitalized costs include the cost of drilling and equipping all wells, lease
acquisition costs, seismic and other geological and geophysical costs, delay
rentals and costs related to such activities. Employee costs associated with
production and other operating activities and general corporate activities are
expensed in the period incurred. For the three months ended September 30, 2004
and 2003, we capitalized certain employee-related costs of approximately $1.3
million and none, respectively. For the nine months ended September 30, 2004
and 2003, we capitalized certain employee-related costs of approximately $3.1
million and none, respectively.

Where proved reserves are established, capitalized costs are limited on a
country-by-country basis (the ceiling test). The ceiling test is calculated as
the sum of the present value of future net cash flows related to estimated
production of proved reserves, using end-of-the-current-period prices,
discounted at 10%, plus the lower of cost or estimated fair value of unproved
properties,

                      ENDEAVOUR INTERNATIONAL CORPORATION
                          (A DEVELOPMENT STAGE ENTITY)
                   NOTES TO CONDENSED CONSOLIDATED STATEMENTS
                                  (UNAUDITED)


all net of expected income tax effects. Under the ceiling test, if the
capitalized cost of a full cost pool exceeds the ceiling limitation, the excess
is charged as an impairment expense.

We utilize a single cost center for each country where we have operations for
amortization purposes. Any conveyances of properties are treated as adjustments
to the cost of oil and gas properties with no gain or loss recognized unless
the operations are terminated in the entire cost center or the conveyance is
significant in nature.

The costs of investments in unproved properties and portions of costs
associated with major development projects are excluded from the depreciation,
depletion and amortization ("DD&A") calculation until the project is evaluated.
Since we are in the start-up phase of our operations, all costs are currently
associated with undeveloped properties.

Unproved property costs include leasehold costs, seismic costs and other costs
incurred during the exploration phase. In areas where proved reserves are
established, significant unproved properties are evaluated periodically for
impairment. If a reduction in value has occurred, these property costs are
considered impaired and are transferred to the related full cost pool. Unproved
properties whose acquisition costs are not individually significant are
aggregated, and the portion of such costs estimated to be ultimately
nonproductive, based on experience, is amortized to the full cost pool over an
average holding period.

In countries where the existence of proved reserves has not yet been
determined, leasehold costs, seismic costs and other costs incurred during the
exploration phase remain capitalized in unproved property cost centers until
proved reserves have been established or until exploration activities cease. If
exploration activities result in the establishment of a proved reserve base,
amounts in the unproved property cost center are reclassified as proved
properties and become subject to depreciation, depletion and amortization and
the application of the ceiling test. If exploration efforts in a country are
unsuccessful in establishing proved reserves, it may be determined that the
value of exploratory costs incurred have been permanently diminished in part or
in whole. Based on the impairment evaluation and future exploration plans, the
unproved property cost centers related to areas of interest could be impaired,
and accumulated costs charged against earnings.

We have restated all prior financial statements as a result of the conversion
to full cost accounting. As a part of this process, all previous charges
related to the successful efforts method of accounting for oil and gas assets
were reversed, increasing the book value of properties as well as our
stockholders' equity. The full cost method, however, requires performing
quarterly ceiling tests to ensure that the carrying value of oil and gas assets
on the balance sheet is not overstated. In ceiling tests performed for the
quarter ended December 31, 2003, a $10.1 million impairment was recorded as
capitalized costs exceeded the ceiling test limits. The ceiling test was based
on natural gas prices of $4.735 per thousand cubic feet (Mcf) that included
adjustments for basis differentials and other pricing factors. Future quarterly
full cost ceiling tests will be based on the current market prices for both
natural gas and oil. The end

result of the full cost conversion is that both the book value of our
properties and stockholders' equity are at approximately the same levels that
would have existed if we had continued with the successful efforts method of
accounting as of December 31, 2003.

STOCK-BASED COMPENSATION ARRANGEMENTS

In accordance with the provisions of Statement of Financial Accounting Standard
("SFAS") No. 123, "Accounting for Stock-Based Compensation," as amended by SFAS
No. 148, "Accounting for Stock-Based Compensation - Transition and Disclosure,"
our stock-based employee compensation plans are accounted for under the
intrinsic value method that requires compensation expense to be recorded only
if, on the date of grant, the current market price of our common stock exceeds
the exercise price the employee must pay for the stock. The intrinsic value of
unvested stock-based compensation is recorded as deferred compensation and
amortized on a straight-line basis over the vesting period of the award.

The net loss for both the three and nine months ended September 30, 2003
includes stock-based compensation cost of $212,000 related to options and
restricted stock granted to a prior director. During 2003, the Company repriced
500,000 options granted to prior directors from an exercise price of $5.00 per
share to $2.30 per share. This modification in 2003 of the options granted to
prior directors triggered variable accounting under APB 25 and FASB
Interpretation No. 44. This requires recording compensation expense if the
modified option price is lower than the market price of the stock at the end of
each reporting period until the options expire or are exercised. For the third
quarter of 2004 and 2003, we recorded a non-cash increase (reduction) in
general and administrative expenses of $(84,000) and none, respectively,
related to these options. For the nine months ended September 30, 2004 and
2003, we recorded non-cash general and administrative expenses of $574,000 and
none, respectively, related to these options. See Note 9 for a discussion of
the restricted stock and stock option grants during 2004.

Had compensation expense for stock option plans been determined based on the
fair value at the grant date for awards through September 30, 2004 consistent
with the provisions of SFAS No. 123, our net loss and net loss per share would
have been reduced to the pro forma amounts indicated below:

NOTE 3 - THE OFFERING, MERGER AND RESTRUCTURING

On February 26, 2004, we completed a series of mutually interdependent
transactions to significantly expand our scope and objectives under the
leadership of a new management team.

THE OFFERING

In an offering of common stock (the "Offering") that closed February 26, 2004,
we issued 25 million shares of common stock at $2.00 per share in a private
placement. The estimated net proceeds of the Offering were $46 million, after
offering costs of $3.9 million. In addition, warrants to purchase 700,000
shares of common stock at $2.00 per share were issued to the placement agent.
The net proceeds were used for the purchase of approximately 14.1 million
shares of our common stock and 103,500 shares of our Series B Preferred Stock
for $5.3 million and for $1.5 million for repayment of the principal amount of
certain outstanding convertible notes, with the remainder of the net proceeds
to be used for general corporate purposes, including potential acquisitions.

THE MERGER

Concurrent with the closing of the Offering, we acquired NSNV, Inc. ("NSNV"),
through a merger (the "Merger") of NSNV into a newly created Delaware corporate
subsidiary of the Company. The newly created subsidiary was the survivor of the
Merger and is a wholly-owned subsidiary of the company that was renamed
Endeavour Operating Corporation. NSNV was a private company owned by William L.
Transier, John N. Seitz and PGS Exploration (UK) Limited ("PGS"), a United
Kingdom corporation that is a provider of geophysical services. The former
shareholders of NSNV received an aggregate of 12.5 million shares of common
stock of

common stock of the Company immediately after the closing of the Merger.

The Merger was accounted for as a purchase of assets and not a business
combination. Therefore, the consideration given was allocated to the fair value
of the identifiable assets and liabilities acquired. Any consideration given in
excess of the fair value of identifiable assets acquired was expensed.

The following is a calculation of the consideration given:

THE RESTRUCTURING

Simultaneous with the consummation of the Merger and the Offering, we
restructured various financial and shareholder related items (the
"Restructuring"). Specifically, completed were the following:

     o   Repaid $1.5 million principal amount of our outstanding convertible
         notes;

     o   Issued 1,026,624 shares of our common stock in exchange for the $1.55
         million principal balance and accrued interest due under the Michael
         P. Marcus convertible debenture at a conversion price of $1.75;
     o   Issued 375,000 shares of our common stock in exchange for the $600,000
         principal balance and accrued interest due under the Trident
         convertible debenture at a conversion price of $1.60;
     o   Issued 2,808,824 shares of our common stock upon conversion of all of
         the outstanding Series C Preferred Stock, and accrued dividends, at a
         conversion price of $1.70 per share;
     o   Purchased all outstanding shares of Series A Preferred Stock and
         20,212.86 shares of Series B Preferred Stock in exchange for certain
         of our non-core assets (see below); and
     o   Purchased 14,097,672 shares of common stock and 103,500.07 shares of
         Series B Preferred Stock from RAM Trading, Ltd. (who held more than
         10% of our outstanding stock prior to this purchase) for approximately
         $5.3 million in cash.

As consideration for the acquisition of all of the Series A Preferred Stock and
20,212.86 shares of the Series B Preferred Stock, we exchanged the following
non-core assets with CSOR Preferred Liquidation, LLC, a newly created entity
owned by the former holders of the Series A Preferred Stock and certain former
holders of the Series B Preferred Stock:

     o   100% of the ownership interest in BWP Gas, LLC.;
     o   864,560 shares of restricted common stock of BPK Resources, Inc.;
     o   400,000 shares of common stock of Trimedia Group, Inc.;
     o   Note receivable due from CSR Hackberry, LLC in the principal amount of
         $25,000;
     o   Note receivable due from Snipes, LLC in the principal amount of
         $122,500;
     o   Subscription receivable due from FEQ Investments in the principal
         amount of $175,000;
     o   Subscription receivable due from GWR Trust in the principal amount of
         $250,000; and
     o   Note receivable due from BPK Resources, Inc. in the principal amount
         of $670,000.

As consideration for services rendered in connection with the purchase of the
shares of common stock and Series B Preferred stock from RAM, we issued to an
unrelated party 300,000 shares of our common stock.

During the first quarter of 2004, the Company sold all of its limited
partnership units in Knox Miss Partners, L.P. for $5 million and received
$500,000 in cash and a $4.5 million short-term note that is secured by a pledge
of the limited partnership interest. At September 30, 2004, the $4.5 million
short-term note has been paid in full.

During the second quarter of 2004, we sold all of our equity interest in
Louisiana Shelf Partners, L.P. for $250,000 in cash and a $2 million contingent
deferred payment that is payable from proceeds from production of drilling
activities on the oil and gas leases held by Louisiana Shelf Partners, L.P.
With the uncertainty of collection of the contingent deferred payment, no
receivable was recorded at the time of the sale. In connection with the sale,
we recorded a loss of $895,000 during the second quarter of 2004.

NOTE 5 - MARKETABLE SECURITIES

In May 2004, we received 1.2 million common shares of Touchstone Resources USA,
Inc. (a public company trading on the OTC Bulletin Board) (the "Touchstone
Shares") in exchange for $3.6 million of convertible promissory notes of
Touchstone Resources, Ltd. (the "Touchstone Exchange"). The net book value of
the convertible promissory notes was zero; as such, we recorded a non-cash gain
on the Touchstone Exchange of approximately $1.8 million, the market value of
the Touchstone Shares on the date of the exchange. The Touchstone Shares
reflected in these financial statements are deemed by management to be
"available-for-sale" and, accordingly are reported at fair value, with
unrealized gains and losses reported in other comprehensive income. At
September 30, 2004, the fair value of the Touchstone Shares was $1.2 million
with a $612,000 unrealized loss recognized in other comprehensive income.


NOTE 6 - SUPPLEMENTAL CASH FLOW INFORMATION

We had noncash investing activities with the purchase of NSNV for 12.5 million
shares of our common stock with a total purchase price of approximately $25
million. Therefore, the Merger increased current assets by $1 million, oil and
gas properties by $11.4 million, other assets by $8.3 million, current
liabilities by $2.5 million, other liabilities by $3.5 million, and equity by
$25 million through a noncash transaction that was not reflected in the
statement of cash flows. However, $66,000 of acquisition costs reflected in
"investing activities" in the statement of cash flows represents the cash
expenses paid in connection with the Merger, less the cash of NSNV on the date
of the Merger. Noncash investing activities also were incurred with the
exchange of certain non-core assets, including BWP Gas, LLC, for all of the
Series A Preferred Stock and 20,212.86 shares of the Series B Preferred Stock,
and the Touchstone Exchange. Noncash financing activities were also incurred,
including the conversion of all of our Series C Preferred Stock and a portion
of our convertible notes into common stock.


NOTE 7 - LEASES

We are the lessee of various items of computer equipment under capital leases
expiring in various years through 2006. The assets and liabilities under
capital leases are recorded at the lower of the present value of the minimum
lease payments or the fair value of the assets. The assets are depreciated over
the lower of their related lease terms or their estimated productive lives.
Depreciation of assets under capital leases is included in depreciation
expense.

Minimum future lease payments under capital leases as of September 30, 2004,
for each of the next three years and in the aggregate are:

Interest rates on capitalized leases are approximately 3.5% and are imputed
based on the lower of the Company's incremental borrowing rate at the inception
of each lease or the lessor's implicit rate of return.


NOTE 8 - LOSS PER SHARE

Loss per common share is calculated in accordance with SFAS No. 128, "Earnings
Per Share." Basic loss per common share is computed by dividing net loss
attributable to common stockholders by the weighted average number of common
shares outstanding. Diluted loss per share is computed similarly to basic loss
per share except that the denominator is increased to include the number of
additional common shares that would have been outstanding if potentially
dilutive common shares had been issued and if the additional common shares were
dilutive. Shares associated with stock options, warrants and convertible debt
are not included in the calculation of weighted average number of common shares
outstanding because their inclusion would be antidilutive (i.e., reduce the net
loss per share). At September 30, 2004, there were potentially dilutive shares
of approximately 1.9 million.

common stock, $.001 par value per share, were issued at a purchase price of
$2.00 per share.

We exercised our call option to buy back 10 of the Company's 99 limited
partnership units in Knox Miss Partners, L.P. from RAM Trading, Ltd. on
February 10, 2004 and issued 835,000 shares of our common stock in full payment
of the option. All of our interest in Knox Miss Partners, L.P. was sold in
February 2004.

During the second quarter of 2004, in a private offering, we issued 175,000
shares of our common stock to fulfill a commitment made for services performed
in connection with the Merger.

Effective June 21, 2004, certificates of withdrawal were filed with respect to
our Series A and Series C preferred stock.

Effective September 17, 2004, we registered for sale approximately 40 million
shares of our common stock that were previously issued to numerous stockholders
in the Offering or were required to be registered upon registration of the
Offering shares. We did not and will not receive any proceeds from the
registration of these shares of our common stock.

LEGAL PROCEEDING

On or about March 4, 2004, the GHK Company, LLC, GHK/Potato Hills Limited
Partnership, and Brian F. Egolf (collectively "Plaintiffs") commenced an action
against Endeavour International Corporation ("Endeavour"), f/k/a Continental
Southern Resources, Inc., as well as BWP Gas, L.L.C. ("BWP") and HBA Gas, Inc.
("HBA") (collectively "defendants") in state court in Oklahoma City, Oklahoma.
In the petition, Plaintiffs allege that Endeavour intended to acquire a
majority of the membership interests in BWP and that HBA in turn entered into
an agreement to assign Plaintiffs 2.5 million common shares of Endeavour stock
upon compliance by Plaintiffs with certain contractual obligations including
but not limited to completion and initial commercial production of the Mary
#2-34 well, along with the presentation of a development plan and the
commencement of the next exploration or development well in the Potato Hills
Deep Prospect. Plaintiffs further allege in their petition that BWP, HBA and
Endeavour are alter egos of each other and jointly and severally liable to
Plaintiffs for failing to deliver to Plaintiffs the Endeavour common stock.
Plaintiffs seek delivery of the stock as well as a temporary restraining order
and a primary and permanent injunction (i) enjoining all dilutions of
Plaintiffs rights pertaining to Endeavour stock; (ii) enjoining Endeavour from
all future stock issuances and transfers of assets not in the ordinary course
of business and (iii) prohibiting the alienation or encumbrance of the
Endeavour stock that is allegedly in HBA's possession. On April 6, 2004, the
defendants removed the action from the state court to the United States
District Court for the Western District of Oklahoma. On October 21, 2004 the
United States District Court granted the motion to remand to state court filed
by the Plaintiffs and remanded the matter to the District Court of Oklahoma
County, Oklahoma. Management intends to litigate vigorously and believes it has
good and valid defenses in this litigation. However, as of this time, counsel
is unable to opine on the outcome of the litigation.


NOTE 13 - SUBSEQUENT EVENTS

On October 12, 2004, we announced that one of our wholly-owned subsidiaries
entered into an agreement to acquire a majority interest in OER Oil AS ("OER"),
a privately held Norwegian exploration and production company based in Oslo,
for approximately $26 million in cash. The transaction is expected to close by
the end of the year subject to necessary government approvals and certain other
conditions.

Following the closing, we will hold the approximately 76 percent interest in
OER previously held by Lundin Petroleum B.V. We have made an offer to purchase
the remaining minority interests in OER, which includes interests held by OER
management, for a combination of our common stock and cash. OER management has
endorsed the acquisition as a means to establish the combined entity as a
leading independent exploration and production company in the Norwegian sector.

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

Unless the context otherwise requires, references to the "Company",
"Endeavour", "we", "us" or "our", mean Endeavour International Corporation or
any of our consolidated subsidiaries or partnership interests. The following
discussion should be read in conjunction with our Condensed Consolidated
Financial Statements and related Notes thereto included elsewhere in this
Report.

GENERAL

During the first quarter of 2004, we completed a series of mutually
interdependent transactions that significantly expanded our scope and
objectives - the Offering, the Merger and the Restructuring as discussed in
Note 3 to the Condensed Consolidated Financial Statements herein. With the
transactions, we have a new focus, primarily on international oil and gas
exploration.

As a result of these transactions, all of our producing operations were sold as
well as our exploration activities in Mississippi. We retained our equity
interests in Thailand and Louisiana through the end of the first quarter;
however our equity interest in Louisiana was sold in May 2004. In addition, all
of the outstanding balances of our convertible debt were either repaid or
converted to common stock. Further, substantially all of our outstanding
preferred stock was repurchased or converted to common stock.

UNITED KINGDOM

During the second quarter of 2004, we participated in the 22nd Seaward
Licensing Round in the United Kingdom in a significant manner. Acting alone and
with others, we were awarded nine production licenses covering 18 blocks in
September 2004.

Endeavour will serve as operator of five production licenses located in the
Central North Sea. These licenses, and our interest therein, include:

     o   Blocks 21/11c and 20/15b (100 percent equity)
     o   Block 21/20c (100 percent equity)
     o   Blocks 22/24e (60 percent equity)
     o   Block 30/23b (60 percent equity )
     o   Blocks 31/26b and 39/1b (60 percent equity)

The company was also awarded a non-operated 47.5 percent equity in Blocks
23/16e and 23/17b in the Central North Sea. Other non-operated licenses and our
interests therein include the following in the Southern Gas Basin:

     o   Blocks 42/10 and 42/15 (50 percent equity)
     o   Blocks 43/22, 43/23, 43/27b, 43/28 and 43/29 (25 percent equity)
     o   Blocks 44/21c and 44/25b (25 percent equity)

The licenses cover more than a half million acres, approximately 2,160 square
kilometers, or the equivalent to more than 100 Gulf of Mexico blocks. Of the
production licenses, four licenses covering eight blocks were granted under
traditional terms that require the company to fulfill a work program within
four years from the date of award. The remaining five licenses covering 10
blocks are under "promote" terms that allow the company to pay reduced license
fees for a two-year period as exploratory evaluations are conducted.

NORWAY

On September 21, 2004, we announced that we were notified by the Ministry of
Petroleum and Energy in Norway of our pre-qualification as a licensee on the
Norwegian Continental Shelf. The process evaluates the competency of a company
from a financial, technical and organizational perspective to participate in
exploration and production activities on the Norwegian Continental Shelf. It
also considers the company's competency concerning issues related to health,
safety and the environment.

On October 12, 2004, our wholly-owned subsidiary, Endeavour Energy Norge AS,
entered into an agreement to acquire a majority interest in OER Oil AS ("OER"),
a privately held Norwegian exploration and production company based in Oslo,
for approximately $26 million in cash. The transaction is expected to close by
the end of the year subject to necessary government approvals and certain other
conditions.

Following the closing, we will hold the approximately 76 percent interest in
OER previously held by Lundin Petroleum B.V. We have made an offer to purchase
the remaining minority interests in OER, which includes interests held by OER
management, for a combination of our

common stock and cash. OER management has endorsed the acquisition as a means
to establish the combined entity as a leading independent exploration and
production company in the Norwegian sector.

THAILAND

Through a limited liability company in which we hold an interest, we have an
interest in the Phu Horm Gas Field Project, an onshore gas discovery in
northern Thailand. In May 2004, the Phu Horm Project was approved as a
Production Area by the Thailand Department of Mineral Fuels. Drilling of two
additional appraisal wells commenced during the second quarter of 2004. These
wells have been completed successfully and tested gas and have expanded the
known limits of the reservoir. Engineering, design and permitting for the gas
production facilities for the project are continuing. A gas sales agreement is
in place to provide gas to the existing Nam Phong power plant. First gas sales
are expected to commence from the Phu Horm Project in 2006. In addition, we
have interests in two exploration licenses in proximity to the Phu Horm Project
which have certain work commitments and obligations.

RESULTS OF OPERATIONS

Impairment of oil and gas properties of $15 million during 2003 represents all
drilling costs incurred through September 30, 2003 plus 100% of the lease
acquisition costs for the entire Hell Hole Prospect. The wells were dry and all
of the leasehold for this prospect were relinquished.

Bad debt expenses were $1.2 million during the nine months ended September 30,
2003 and consisted of impairment charges related to our investment in
Touchstone Resources, Ltd. At December 31, 2003, all investments in Touchstone
Resources, Ltd. were fully impaired. As discussed in Note 5, we received 1.2
million shares of Touchstone USA, Inc. in exchange for our convertible
promissory notes of Touchstone Resources, Ltd. and recorded a gain of $1.8
million.

General and administrative ("G&A") expenses increased to $3.7 million during
the three months ended September 30, 2004 as compared to $981,000 for the
corresponding period in 2003 and increased to $9.1 million during the nine
months ended September 30, 2004 as compared to $1.9 million for the
corresponding period in 2003. Components of G&A expenses for these periods are
as follows:

Other income increased to $143,000 during the three months ended September 30,
2004 as compared to other expense of $944,000 for the corresponding period in
2003 primarily due to interest expense on convertible debt during 2003. Other
expense increased to $8.6 million during the nine months ended September 30,
2004 as compared to $2.7 million for the corresponding period in 2003. The 2004
expense consisted of a $10.8 million expense for consideration given in excess
of fair value of identifiable assets acquired in the Merger, interest expense of
$262,000 incurred primarily on outstanding convertible debt and a $207,000 loss
in on the sale of marketable securities as part of the Restructuring, partially
offset by $355,000 net gain in connection with our sales of our partnership
interests and $1.8 million in income related to the gain on the Touchstone
Exchange. The 2003 other expense consisted primarily of interest expense of $2.9
million incurred on outstanding convertible debt. All of the convertible debt
was sold or converted to common stock as part of the Restructuring. With the
Restructuring of all of the outstanding convertible debt, we do not expect to
incur significant interest expense for the remainder of 2004.

LIQUIDITY AND CAPITAL RESOURCES

On February 4, 2004, a private placement for 125,000 shares of our common
stock, $.001 par value per share, at a purchase price of $2.00 per share, was
completed.

On February 26, 2004, we completed an offering of 25 million shares of our
common stock for estimated net proceeds of $46 million, after offering costs of
$3.9 million. In addition, warrants to purchase 700,000 shares of common stock
at an exercise price of $2.00 per share were issued to the placement agent. The
net proceeds were used for the purchase of approximately 14.1 million shares of
common stock and 103,500 shares of our Series B Preferred Stock for $5.3
million and for the repayment of $1.8 million of the principal amount of
certain outstanding convertible notes and other notes, with the remainder of
the net proceeds to be used for general corporate purposes, including potential

In combination with the Offering of $50 million of gross proceeds, our ability
to issue additional equity or utilize our debt capacity, we believe we have
sufficient funding to continue to execute

our business plan for the next several years. Our proposed purchase of OER,
including our intent to offer to purchase the remaining minority interests, is
anticipated to be initially financed through a combination of our common stock
and cash. We are currently discussing long-term debt options with financial
institutions and expect that our financing capacity will be adequate to fund a
portion of the cash acquisition cost of OER.

ITEM 3:  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our cash balances are primarily maintained in money market accounts with U.S.
financial institutions and as such, we do not believe we are exposed to
significant market or currency risk.


ITEM 4:  CONTROLS AND PROCEDURES

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

         As of the end of the period covered by this report, our management
carried out an evaluation, with the participation of our co-chief executive
officers (the "CEOs") and our chief accounting officer (the "CAO"), of the
effectiveness of our disclosure controls and procedures required by Rule 13a-15
of the Securities Exchange Act of 1934. Based on that evaluation, the CEOs and
CAO believe:

         (i)      that our disclosure controls and procedures are designed to
                  ensure that information required to be disclosed by us in the
                  reports that we file or submit under the Securities Exchange
                  Act of 1934 is recorded, processed, summarized and reported
                  within the time periods specified in the SEC's rules and
                  forms, and that such information is accumulated and
                  communicated to our management, including the CEOs and CAO, as
                  appropriate to allow timely decisions regarding required
                  disclosure; and

         (ii)     that our disclosure controls and procedures are effective.

CHANGES IN INTERNAL CONTROLS OVER FINANCIAL REPORTING

         There has been no significant change in our internal controls over
financial reporting during the period covered by this report that has
materially affected, or is reasonably likely to materially affect, our internal
controls over financial reporting.



PART II. OTHER INFORMATION
ITEM 1:  LEGAL PROCEEDINGS

On or about March 4, 2004, the GHK Company, LLC, GHK/Potato Hills Limited
Partnership, and Brian F. Egolf (collectively "Plaintiffs") commenced an action
against Endeavour International Corporation ("Endeavour"), f/k/a Continental
Southern Resources, Inc., as well as BWP Gas, L.L.C. ("BWP") and HBA Gas, Inc.
("HBA") (collectively "defendants") in state court in Oklahoma City, Oklahoma.
In the petition, Plaintiffs allege that Endeavour intended to acquire a
majority of the membership interests in BWP and that HBA in turn entered into
an agreement to assign Plaintiffs 2.5 million common shares of Endeavour stock
upon compliance by Plaintiffs with certain contractual obligations including
but not limited to completion and initial commercial production of the Mary
#2-34 well, along with the presentation of a development plan and the
commencement of the next exploration or development well in the Potato Hills
Deep Prospect. Plaintiffs further allege in their petition that BWP, HBA and
Endeavour are alter egos of each other and jointly and severally liable to
Plaintiffs for failing to deliver Plaintiffs the Endeavour common stock.
Plaintiffs seek delivery of the stock as well as a temporary restraining order
and a primary and permanent injunction (i) enjoining all dilutions of
Plaintiffs rights pertaining to Endeavour stock; (ii) enjoining Endeavour from
all future stock issuances and transfers of assets not in the ordinary course
of business and (iii) prohibiting the alienation or encumbrance of the
Endeavour stock that is allegedly in HBA's possession. On April 6, 2004, the
defendants removed the action from the state court to the United States
District Court for the Western District of Oklahoma. On October 21, 2004 the
United States District Court granted the motion to remand to state court filed
by the Plaintiffs and remanded the matter to the District Court of Oklahoma
County, Oklahoma. Management intends to litigate vigorously and believes it has
good and valid defenses in this litigation. However, as of this time counsel is
unable to opine on the outcome of the litigation.


ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

At the Annual Meeting of Stockholders of the Company held on August 24, 2004,
the stockholders elected five directors to serve terms expiring in 2005, 2006
and 2007, and approved the 2004 Incentive Plan.
