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.
This Form 8-K 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 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

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:

      -     a new management team;

      -     a new business strategy of exploration, exploitation and acquisition
            that will be focused on the North Sea;

      -     the acquisition of NSNV, Inc. which possessed the seismic data and
            management team that will be central to the Company's new strategy;
            and

      -     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 June 30, 2004 and
2003, we capitalized certain employee - related costs of approximately $1.3
million and none, respectively. For the six months ended June 30, 2004 and 2003,
we capitalized certain employee - related costs of approximately $1.8 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,

                                       7

                       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 suspended 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.

The effect of the accounting change on net loss follows:

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 2003 does not include any stock-based compensation cost, as
there were no stock-based compensation arrangements outstanding through June 30,
2003. Stock-based compensation was granted in the fourth quarter of 2003 by our
previous Board of Directors. 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
each reporting period until the options expire or are exercised. For the second
quarter of 2004, we recorded a non-cash reduction in general and administrative
expenses of $448,000 related to these options. For the six months ended June 30,
2004, we recorded non-cash general and administrative expenses of $658,000
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 June 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 the Company in the Merger, representing approximately 18.9% of
outstanding 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:

"Restructuring"). Specifically, completed were the following:

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

      -     Issued 1,026,624 shares of our common stock in exchange for the
            $1.55 million principal balance and accrued interest due under the

      -     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;

      -     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;

      -     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

      -     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:

      -     100% of the ownership interest in BWP Gas, LLC.;

      -     864,560 shares of restricted common stock of BPK Resources, Inc.;

      -     400,000 shares of common stock of Trimedia Group, Inc.;

      -     Note receivable due from CSR Hackberry, LLC in the principal amount
            of $25,000;

      -     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.

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"). At December 31, 2003,
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 June 30, 2004, the fair value of the Touchstone Shares was $1.7 million with
a $108,000 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 June 30, 2004, for each
of the next three years and in the aggregate are:

</TABLE>

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 because their inclusion would be antidilutive (i.e., reduce the
net loss per share). At June 30, 2004, there were potentially dilutive shares of
approximately 2.8 million.

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 Endeavour 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 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, a primary and permanent injunction (i) enjoining all
dilutions of Plaintiff 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 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, as of this time, counsel is unable to opine on the outcome of the
litigation.

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
unaudited 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.

During the second quarter of 2004, we participated in the 22nd licensing round
in the United Kingdom in a significant manner. Acting alone and with others, we
submitted eight applications covering 21 blocks. Four of these applications were
promote applications and four were

                                       20
<PAGE>

                       ENDEAVOUR INTERNATIONAL CORPORATION

traditional applications. Pursuant to the applications, we committed to
undertake certain work obligations. We expect the United Kingdom government to
announce the results of the 22nd licensing round in August or September 2004. We
are also considering other opportunities in the United Kingdom sector of the
North Sea, including possible farm-ins to existing licenses.

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, which are expected to be
completed in the fall of 2004. Engineering, design and permitting for the gas
production facilities for the project are continuing at this time. 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 early
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

General and administrative expenses increased to $3.0 million during the three
months ended June 30, 2004 as compared to $730,000 for the corresponding period
in 2003 and increased to $5.5 million during the six months ended June 30, 2004
as compared to $975,000 for the corresponding period in 2003. For the second
quarter of 2004, we recorded a non-cash reduction in general and administrative
expenses of $448,000 related to the mark-to-market adjustment of options under
variable plan accounting. For the six months ended June 30, 2004, we recorded
non-cash general and administrative expenses of $658,000 related to these same
options. In addition, general and administrative expenses for the second quarter
of 2004 included approximately $1.9 million in non-cash charges for the
amortization of deferred compensation granted to the new management and
employees after the Merger in February 2004, and $2.9 million for the six months
ended June 30, 2004. For the three months ended June 30, 2004 and 2003, we
capitalized certain employee - related costs of approximately $1.3 million and
none, respectively. For the six months ended June 30, 2004 and 2003, we
capitalized certain employee - related costs of approximately $1.8 million and
none, respectively. Expenses for the three months and six months ended June 30,
2003 consisted primarily of professional fees, compensation and consulting fees.

Bad debt expenses were $900,000 during the six months ended June 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.

Other income increased to $1.1 million during the three months ended June 30,
2004 as compared to other expense of $1.0 million for the corresponding period
in 2003. The other income for the second quarter of 2004 consisted primarily of
$1.8 million in income related to the gain on the Touchstone Exchange, partially
offset by the $895,000 loss on the sale of our

                                       21

                       ENDEAVOUR INTERNATIONAL CORPORATION

interest in Louisiana Shelf Partners, Inc. The other expense for the second
quarter of 2003 consisted primarily of interest expense on convertible debt.
Other expense increased to $8.8 million during the six months ended June 30,
2004 as compared of $1.8 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
$254,000 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 The 2003 other expense consisted primarily of interest expense of $1.9
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
acquisitions.

After completion of the Offering with $50 million of gross proceeds, we believe
we have sufficient funding at least through the end of 2005 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.

DISCLOSURES ABOUT CONTRACTUAL OBLIGATIONS AND COMMERCIAL COMMITMENTS

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

      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.

PART II. OTHER INFORMATION

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, a primary and permanent injunction (i) enjoining
all dilutions of Plaintiff 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 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, as of this time counsel is unable to opine on the outcome of the

1933, as amended, pursuant to Section 4(2) thereof or Rule 506 of Regulation D
promulgated thereunder without payment of underwriting discounts or commissions
to any persons.

private offering.

ITEM 5. OTHER INFORMATION
