                        NOTES TO CONSOLIDATED STATEMENTS
                                   (UNAUDITED)


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 the 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.

In 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).

NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES

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 net loss for 2003 does not include any stock-based compensation cost, as
there was no stock-based compensation outstanding during the first quarter of
2003. The modification in 2003 of 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
a reporting period until the options expire or are exercised. Since the modified
option exercise price for the 700,000 options was lower than the market price of
the stock at March 31, 2004, we recorded non-cash compensation expense of
$1,106,000 under APB 25 for the quarter ended March 31, 2004. See Note 7 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 March 31, 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:

These pro forma amounts may not be representative of future disclosures since
the estimated fair value of stock options is amortized to expense over the
vesting period and additional options may be issued in future years. The
estimated fair value of each option granted was calculated using the
Black-Scholes Method. The following summarizes the weighted average of the
assumptions used in the method.

OTHER PROPERTY, PLANT AND EQUIPMENT

Other oil and gas assets and furniture and fixtures are recorded at cost, less
accumulated depreciation. The assets are depreciated using the straight-line
method over their estimated useful lives of two to five years.

NOTE 3 - THE OFFERING, MERGER AND RESTRUCTURING

On February 29, 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 $46,000,000, after
deduction of placement agent commissions of $2,500,000, financial advisory fees
of $1,250,000 and offering expenses of $101,000. 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 common stock and 103,500.07 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 in the Merger, representing approximately 18.9% of outstanding common
stock 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.

      properties.

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 $1,500,000 principal amount of our outstanding convertible notes;

   o  Issued 1,026,624 shares of our common stock in exchange for the $1,550,000
      principal balance and accrued interest due under the Michael P. Marcus
      convertible debenture at a conversion price of $1.75;

   o  Issued 2,808,824 shares of our common stock upon conversion of all of the

   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 that 10% of
      our outstanding stock prior to this purchase) for $5,330,948 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 BPK Resources, Inc. with a principal balance of

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 $5,000,000 and received
$500,000 in cash and a $4,500,000 short-term note that is secured by a pledge of
the limited partnership interest.

NOTE 4 - 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 property 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, $65,811 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. Noncash financing activities were also incurred, including the
conversion of all of our Series C Preferred Stock and our convertible notes into
common stock.

NOTE 5 - LEASES

We are the lessee of various 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 asset. 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 March 31, 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 company's incremental borrowing rate at the inception of
each lease or the lessor's implicit rate of return.

NOTE 6 - 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 because their inclusion would be antidilutive (i.e., reduce the
net loss per share). At March 31, 2004,

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 the state court in Oklahoma City,
Oklahoma. In the petition, Plaintiffs allege that CSOR intended to acquire a
majority of the membership interests in BWP and that HBA in turn entered into an
agreement to assign Plaintiff 2.5 million common shares of CSOR 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 CSOR common stock. Plaintiffs seek delivery of the stock as
well as a temporary restraining order, a primary and permanent injunction (i)
enjoining all dilutions of Plaintiff rights pertaining to CSOR 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 CSOR stock that is allegedly in Plaintiff'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. Subsequently,
Endeavour made a motion for dismissal of the action for lack of jurisdiction
over Endeavour in Oklahoma. Management intends to litigate vigorously and
believes it has good and valid defenses beyond its jurisdictional defense.
However, the action has just begun and counsel is unable to opine on the outcome
of the litigation.

In May 2004, we completed the sale of our equity interest in Louisiana Shelf
Partners, L.P. for $2,250,000 and received $250,000 in cash and a $2,000,000
contingent deferred payment that is payable from proceeds of drilling activities
on the oil and gas leases held by Louisiana Shelf Partners, L.P. As of March 31,
2004, our net book value in Louisiana Shelf Partners, L.P. was approximately
$1.1 million.

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 Consolidated Financial Statements and
related Notes thereto included elsewhere in this Report.

RESULTS OF OPERATIONS

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
unaudited financial statements herein. With the transactions, we have a new
focus, primarily on international oil and gas exploration, and a license for
seismic data in the North Sea.

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 April 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.

Exploration expenses increase from $610,255 during the first quarter of 2003 to
$2,201,373 during the first quarter of 2004. Exploration expenses for 2004
consisted primarily of the $1.8


                                       15

                       ENDEAVOUR INTERNATIONAL CORPORATION


million expense for the portion of the seismic data, covering 79,200 square
kilometers of the North Sea which was acquired in the Merger, received through
March 31, 2004.

General and administrative expenses increased to $3,027,158 during the three
months ended March 31, 2004 as compared to $245,355 for the corresponding period
in 2003. Expenses for 2004 included a non-cash charge of approximately $1.1
million for the variable plan accounting adjustment for the options granted to
former officers and directors. In addition, general and administrative expenses
for 2004 included approximately $1.1 million in non-cash charges for the
amortization of deferred compensation granted to the new management and
employees after the Merger in February 2004. Expenses for 2003 consisted
primarily of professional fees, officer compensation and consulting fees.

Bad debt expenses were $900,000 during the three months ended March 31, 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.

Other expense increased to $9,920,722 during the three months ended March 31,
2004 as compared to other income of $441,437 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 $252,672 incurred primarily on outstanding convertible debt
and a $206,971 loss in on the sale of marketable securities as part of the
Restructuring, partially offset by $1.2 million gain in connection with our sale
of our partnership interest in Knox Miss., L.P. The 2003 income consisted of a
$1.2 million gain in connection with the sale of CSR-Waha, offset by interest
expense of $846,025. All of the convertible debt and marketable securities were
sold or converted to common stock as part of the Restructuring. The 2003 expense
consisted primarily of interest expense incurred on outstanding convertible
debt. With the repayment or conversion 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 $46,000,000, after deduction of
placement agent commissions of $2,500,000, financial advisory fees of $1,250,000
and offering expenses of $101,000. 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 103,500.07 shares of our
Series B Preferred Stock for $5.3 million and for the repayment of $1.5 million
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.


                                       16

<PAGE>

                       ENDEAVOUR INTERNATIONAL CORPORATION


After completion of the Offering with $50 million of gross proceeds, we believe
we have sufficient funding for at least 24 months to continue to execute our
business plan. Through the Restructuring, there is no outstanding debt and only
immaterial amounts of outstanding preferred stock. Therefore, we do not expect
to incur significant interest expense nor pay significant preferred dividends
for the remainder of 2004.

ANTICIPATED CHANGE IN METHOD OF ACCOUNTING FOR OIL AND GAS OPERATIONS

In May 2004, we expect to request preclearance by the Securities and Exchange
Commission to change our accounting method for oil and gas operations from the
successful efforts method to the full cost method in light of the significant
changes in our operations that have recently occurred. 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  an experienced technical team in both Houston and London;

   o  a new, balanced business strategy of exploration, exploitation and
      acquisition of producing oil and gas properties that will be focused on
      the North Sea; and

   o  the sale of all interests in U.S. oil and gas producing and exploration
      ventures.

We believe that the full cost method of accounting is more appropriate for an
exploration focused company with a large regional concentration and 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. We believe
capitalization of seismic and other exploration technology as well as the cost
of all exploratory wells recognizes the value these expenditures add to the
exploration 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.

We expect that this determination will be made in the second quarter.

ITEM 3: QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our cash balances are primarily maintained in money market accounts and as such,
we do not believe we are exposed to significant market risk.

ITEM 4:  CONTROLS AND PROCEDURES

Our Co-Chief Executive Officers and Chief Accounting Officer performed an
evaluation of our disclosure controls and procedures, which have been designed
to permit us to effectively identify and timely disclose important information.
They concluded that the controls and procedures were effective as of March 31,
2004 to ensure that material information was accumulated and communicated to the
Company's management, including our Co-Chief Executive Officers and


                                       17

                       ENDEAVOUR INTERNATIONAL CORPORATION


Chief Accounting Officer, as appropriate to allow timely decisions regarding
required disclosure. During the three months ended March 31, 2004, no change in
our internal controls over financial reporting has been made 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 the state court in Oklahoma City,
Oklahoma. In the petition, Plaintiffs allege that CSOR intended to acquire a
majority of the membership interests in BWP and that HBA in turn entered into an
agreement to assign Plaintiff 2.5 million common shares of CSOR 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 CSOR common stock. Plaintiffs seek delivery of
the stock as well as a temporary restraining order, a primary and permanent
injunction (i) enjoining all dilutions of Plaintiff rights pertaining to CSOR
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 CSOR stock that is allegedly in Plaintiff'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.
Subsequently, Endeavour made a motion for dismissal of the action for lack of
jurisdiction over Endeavour in Oklahoma. Management intends to litigate
vigorously and believes it has good and valid defenses beyond its jurisdictional
defense. However, the action has just begun and counsel is unable to opine on
the outcome of the litigation.


ITEM 2: CHANGES IN SECURITIES, USE OF PROCEEDS AND ISSUER PURCHASES OF EQUITY
        SECURITIES

In each of the following transactions, the securities were issued in a private
placement exempt from the registration requirements of the Securities Act of
1933, as amended, pursuant to Section 4(2) thereof or Rule 506 of Regulation D
