Note 1 – Summary of Significant Accounting Policies
General
Endeavour International Corporation is an international oil and gas exploration and production company primarily focused on the acquisition, exploration and development of energy reserves in the North Sea. As used in these Notes to Condensed Consolidated Financial Statements, the terms “Company”, “Endeavour”, “we”, “us”, “our” and similar terms refer to Endeavour International Corporation and, unless the context indicates otherwise, its consolidated subsidiaries. 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–K/A for the year ended December 31, 2005.
Basis of Presentation and Use of Estimates
The accompanying financial statements 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.
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.
Income (Loss) Per Share
Basic income (loss) per common share is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding for the period. Diluted income (loss) per share includes the effect of our outstanding stock options, warrants and shares issuable pursuant to convertible debt and certain stock incentive plans under the treasury stock method, if including such instruments is dilutive.

For the six months ended June 30, 2006, 18.4 million common shares potentially issuable, relating to convertible debt, outstanding options and warrants and certain stock incentive plans, were excluded from diluted weighted average shares outstanding as their effects were anti-dilutive (i.e., reduce the net loss per share). For the six months ended June 30, 2005, 14.4 million common shares potentially issuable related to convertible debt and certain stock incentive plans were excluded from diluted weighted average shares outstanding as their effects were anti-dilutive (i.e., increase the net income per share).
Other-Than-Temporary Impairments of Debt and Equity Securities
In November 2005, accounting standards were revised to provide guidance for determining and measuring other-than-temporary impairments of debt and equity securities. The new guidance is effective for reporting periods beginning after December 15, 2005. At June 30, 2006, available-for-sale investments in our marketable securities had unrealized losses totaling $0.9 million which are recorded in Other Accumulated Comprehensive Income. This investment represents equity securities in a publicly traded oil and gas exploration company. We have determined that the unrealized losses as of June 30, 2006 do not represent an other-than-temporary decline in value, primarily due to both our assessment that there are no specific adverse conditions affecting the investment, and our ability to hold the investment through a downturn in market value which may be caused by results of short-term exploration activities. If our assessment regarding these factors were to change, we may be required to record an impairment charge equal to the difference between the fair value of the securities and the amortized cost of the securities.

Adoption of Fair Value Accounting for Share-Based Payments
In December 2004, the Financial Accounting Standards Board (“FASB”) revised rules that require all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements based on their fair values. We adopted these new rules effective January 1, 2006 using the modified prospective method in which the prior period financial statements are not restated. The share-based compensation cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense over the employee’s requisite service period (generally the vesting period of the equity award). Prior to January 1, 2006, we accounted for share-based compensation to employees under the intrinsic value method.
The adoption of these new rules resulted in a cumulative effect of change in accounting principle, net of tax, of less than $60,000. Because the amount was immaterial, we have included it in general and administrative expense on our consolidated statement of income.
It is our policy to use unissued shares of stock when stock options are exercised. At June 30, 2006, we had approximately 1.7 million additional shares available for issuance pursuant to our existing stock incentive plan.
New Accounting Developments
In July 2006, the FASB issued an interpretation which clarifies the accounting for uncertainty in income taxes recognized in a company’s financial statements by prescribing a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken in a tax return. The interpretation also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.
This new accounting guidance is effective for fiscal years beginning after December 15, 2006. We are reviewing the interpretation and analyzing the potential impact, if any, of this new guidance.
Note 2 – Stock-Based Compensation Arrangements
We grant restricted stock and stock options, including notional restricted stock and options, to employees and directors as incentive compensation. The notional restricted stock and options may be settled in cash or stock upon vesting, at the Company’s option. It has been the company’s practice to settle in stock. The restricted stock and options generally vest over three years and the options have a five year expiration. The vesting of these shares and options is dependent upon the continued service of the grantees to the Company. Upon the occurrence of a change in control, each share of restricted stock and stock option outstanding on the date on which the change in control occurs will immediately become vested. For the second quarter of

2006, we included non-cash stock-based compensation of $2.1 million and $0.9 million in general and administrative expenses and capitalized general and administrative expenses, respectively. For the six months ended June 30, 2006, we included non-cash stock-based compensation of $4.2 million and $1.9 million in general and administrative expenses and capitalized general and administrative expenses, respectively. At June 30, 2006, total compensation costs related to nonvested awards not yet recognized was approximately $17.0 million and is expected to be recognized over a weighted average period of less than two years.
Stock Options
The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model. Expected volatility is based on an average of our peer companies due to the lack of relevant Endeavour volatility information for the length of the expected term. The expected term is the average of the vesting date and the expiration of the option. We use historical data to estimate option exercises and employee terminations within the valuation model. The risk-free rate for periods within the contractual life of the option is based on the U.S. treasury yield curve in effect at the time of grant. The following table sets forth the assumptions used to determine compensation cost for our non-qualified stock options granted during the six months ended June 30, 2006.

The weighted average grant-date fair value of options granted during 2006 was $1.22 per option.
Prior to January 1, 2006, we recorded shared-based compensation under the intrinsic value method and no compensation expense was recorded for stock options granted when the exercise price of options granted was equal to or greater than the fair market value of our common stock on the date of grant.
We apply the fair value method in accounting for share-based grants to non-employees using the Black-Scholes option-pricing model.
Restricted Stock
At June 30, 2006, our employees and directors held 4.7 million restricted shares of our common stock that vest over the service period of up to three years. The restricted stock awards were valued based on the closing price of our common stock on the measurement date, typically the date of grant, and compensation expense is recorded on a straight-line basis over the restricted share vesting period.
Status of the restricted shares as of June 30, 2006 and the changes during the six months ended June 30, 2006 is presented below:

Pro Forma Disclosures
During 2003, we granted 700,000 options to then-current directors and 495,000 of these options remain outstanding at June 30, 2006. While all the options granted had an exercise price higher than the market value of the stock on the date of grant, a subsequent modification of these options has triggered variable accounting. Prior to the adoption of the fair value method of accounting for stock-based compensation, we were required to record 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. For the three and six months ended June 30, 2005, we recorded non-cash general and administrative expenses of $0.1 million and $(0.4), respectively, related to these options.
Had compensation expense been determined under fair value provisions, our net income and net income per share would have been the following:

Note 3 – Acquisitions and Dispositions
Purchase of Minority Interest in OER Oil AS
In January 2005, we purchased the remaining 23.34% minority interest, representing 1,299,772 shares, in OER Oil AS (“OER”), a privately held Norwegian exploration and production company based in Oslo, Norway (the “OER Acquisition”), for consideration of NOK 6.98 per share in cash and 1.68 shares of our common stock per share of OER. The aggregate consideration paid of $10.7 million was approximately $1.4 million in cash and 2,183,617 shares of our common stock. As a result of this purchase, goodwill increased by $7.7 million.
Purchase of Interest in Enoch Field
During the second quarter of 2006, we invested $12 million for the purchase of an eight percent interest in the Enoch Field located in Block 16/13a in the North Sea.
Sale of Partnership Interests in Thailand Project
During the second quarter of 2005, we sold our partnership interests in Thailand to a private entity for net cash proceeds of approximately $19 million. We recorded a gain on the sale of these interests of approximately $15 million.
Pending Acquisition
During the second quarter of 2006, we announced that our subsidiary, Endeavour Energy UK Limited, entered into an agreement with a subsidiary of Talisman Energy Inc. to purchase all of the outstanding shares of Talisman Expro Limited for US $414 million (the “Talisman Acquisition”). Seven producing fields in the United Kingdom sector of the North Sea are included in the transaction. At June 30, 2006, approximately $14.7 million of various costs to secure financing and professional fees associated with the Talisman Acquisition are included in prepaid expenses and accrued expenses.
We expect to close this transaction before the end of the year with a January 1, 2006 effective date. The purchase is subject to approval of governmental regulatory authorities and third party consents.

The costs not subject to amortization relate to unproved properties and properties being made ready to be placed in service which are excluded from amortized capital costs until it is determined whether or not proved reserves can be assigned to such properties. All the costs related to the acquisition of the Enoch field are classified as unevaluated and are not subject to amortization at June 30, 2006. During 2006, we recorded $0.9 million in impairment of oil and gas properties related to exploratory wells. We capitalized $2.4 million and $1.9 million in certain employee costs directly related to exploration activities for the quarter ended June 30, 2006 and 2005, respectively. We capitalized $5.1 million and $3.5 million in certain employee costs directly related to exploration activities for the six months ended June 30, 2006 and 2005, respectively.
Note 5 – Derivative Instruments
At June 30, 2006 we have an oil commodity swap where we pay market IPE Brent and receive a fixed price that ranges from $41.00 per barrel to $40.00 per barrel. The contract covers 600 barrels per day through December 2006 and has been accounted for as a hedge. For the three and six months ended June 30, 2006, we realized $1.6 million and $2.7 million, respectively, as a reduction to revenue related to settlements for this contract. For the three and six months ended June 30, 2005, we realized $0.4 million and $0.5 million, respectively, as a reduction to revenue related to settlements for this contract. We did not exclude any component of the hedging instrument’s gain or loss when assessing effectiveness. At June 30, 2006, the net deferred loss recognized in accumulated other comprehensive income was $3.1 million, net of tax, all of

which is expected to be transferred out of accumulated other comprehensive income and recognized within earnings over the next 6 months.
We discontinue hedge accounting prospectively when (1) we determine that the derivative is no longer effective in offsetting changes in the fair value or cash flows of a hedged item (including hedged items such as firm commitments or forecasted transactions); (2) the derivative expires; (3) it is no longer probable that the forecasted transaction will occur; (4) a hedged firm commitment no longer meets the definition of a firm commitment; or (5) management determines that designating the derivative as a hedging instrument is no longer appropriate.
In connection with the pending Talisman Acquisition, we entered into various oil and gas derivative instruments to stabilize cash flows from the assets to be acquired. Hedge accounting has not been elected for these instruments and during the second quarter of 2006, we recorded $3.3 million in other expense related to the net unrealized losses for these contracts. The fair market value of these derivative instruments is included in our balance sheet as follows: $7.3 million in prepaid expenses and other current assets; $0.8 million in other long-term assets; $1.5 million in accrued expenses and other current liabilities; and $1.5 million in other long-term liabilities.
At June 30, 2006, we had the following derivative instruments related to future oil and gas production outstanding:

Note 8 – Commitments and Contingencies
General
The oil and gas industry is subject to regulation by federal, state and local authorities. In particular, gas and oil production operations and economics are affected by environmental protection statutes, tax statutes and other laws and regulations relating to the petroleum industry. We believe we are in compliance with all federal, state and local laws and regulations applicable to the Company and its properties and operations, the violation of which would have a material adverse effect on us or our financial condition.
Legal Proceeding
In March 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 certain other entities in state court in Oklahoma City, Oklahoma. During the fourth quarter of 2005, we recorded $5.3 million in litigation settlement expense to reflect the settlement of the litigation between Endeavour and the Plaintiffs on January 25, 2006. The settlement provided for the issuance of 1.5 million shares of our common stock and the granting of certain registration rights. These shares were issued in February 2006 and we have filed a registration statement on Form S-3 in accordance with the terms of the settlement agreement.
Rig Commitments
In the UK, we have a commitment for drilling services with a semi-submersible drilling rig, for two wells in the last half of 2006 for approximately $13.5 million. We joined with several other operators in the Norwegian Continental Shelf to form a consortium that has entered into a contract for the use of a drilling rig for a three-year period beginning the second half of 2006. The agreement allows us to move forward with our exploration program in Norway and fulfill our role as an operator of Norwegian licenses. The contract commits us to 100 days (for two wells) of drilling services, for approximately $37.8 million, between late 2007 and 2008 conducted by Bredford Dolphin, a semi-submersible drilling rig.
During the second quarter of 2006, a wholly owned subsidiary entered into a rig commitment for 220 days over a one-year period beginning in March 2007 for the United Kingdom sector of the North Sea. The value of this contact is approximately $66 million. The arrangement with Applied Drilling Technology International, a division of GlobalSantaFe, will be for the GSF Magellan, a heavy-duty harsh environment jack-up suitable for most drilling activities the company will operate in 2007-2008.

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
We are an international oil and gas exploration and production company focused on the acquisition, exploration and development of energy reserves in the North Sea. Since focusing our operations in the North Sea in February 2004, we have established an exploration portfolio with prospects in the United Kingdom and Norwegian sectors of the North Sea. To date, we have invested a significant amount of our resources on various development, acquisition and exploration projects. We intend to continue to allocate a significant portion of our capital to such projects.
Pending Acquisition
During the second quarter of 2006, we entered into an agreement with a subsidiary of Talisman Energy Inc. to purchase all of the outstanding shares of Talisman Expro Limited for US $414

million (the “Talisman Acquisition”). This acquisition will significantly increase the size of our operations and reserves upon closing, which is expected to occur before the end of the year. The Talisman Acquisition will provide our first production in the UK and should also provide cash flow to support our ongoing exploration drilling program. The purchase is subject to approval of governmental regulatory authorities and third party consents.
The assets to be acquired in the Talisman Acquisition include seven producing fields in the United Kingdom sector of the North Sea with approximately 9,100 barrels of oil equivalent per day in current production. Those producing areas will include the following fields:
                 
    Interest     Operator   Hydrocarbon
Alba
    2.25 %   Chevron   Oil
Bittern
    2.38 %   Shell   Oil/Gas
Goldeneye
    7.50 %   Shell   Gas/Condensate
Ivanhoe, Rob Roy, Hamish
    23.46 %   Hess   Oil
Renee
    77.50 %   Endeavour   Oil
Rubie
    40.78 %   Endeavour   Oil
Rochelle
    55.62 %   Endeavour   Oil
Total estimated cash costs for the Talisman Acquisition, including various costs to secure financing and put a commodity hedging program in place, are estimated to be approximately $469 million. We have secured financing commitments for $550 million — a potential $300 million through a five-year term loan facility that would bear interest at LIBOR plus 4% and a potential $250 million for issuance of convertible preferred stock. We are continuing to pursue these and other financing opportunities and currently anticipate the transaction financing to consist of the following:
         
Net cash flow from January 1, 2006 from the acquired assets (1)
  $ 40  
Cash on hand
    19  
Convertible preferred stock (2)
    125 – 250  
Senior bank facility (3)

(1)   Assumes a September 30, 2006 closing and includes assumed interest paid on acquisition purchase price from January 1, 2006 through September 30, 2006.
 
(2)   Convertible preferred stock would pay 8% dividends in cash or stock, at our option and would have a conversion price of $3.40. Such terms are subject to adjustment upon occurrence of certain events.
 
(3)   North Sea Reserve Based loans typically bear interest at LIBOR plus 1% to 3%.
Results of Operations
Our producing assets are concentrated in Norway with interests in two producing fields, both operated by Norsk Hydro. Oil and condensate sales volumes decreased from the second quarter

of 2005 to the second quarter of 2006 primarily due to planned shut-downs at one of the producing fields for maintenance. Oil and condensate sales volumes decreased from the six months ended June 30, 2005 to the same period of 2006 primarily due to the planned shut-down, the schedule of tanker liftings between the periods and delays in development activities. With the significant increases in worldwide oil and gas commodity prices from 2005 to 2006, our revenues and realized prices have increased correspondingly, partially offset by the losses realized under our oil hedging activities. During the second quarter of 2006 and 2005, we realized $1.6 million and $0.4 million, respectively, as a reduction to revenue related to settlements of oil hedging activities. During the six months ended June 30, 2006 and 2005, we realized $2.7 million and $0.5 million, respectively, as a reduction to revenue related to settlements of oil hedging activities. The following table shows our average sales volumes and sales prices:

Operating expenses decreased by $0.2 million for the six months ended June 30, 2006 as compared to the same period in 2005 primarily due to the scheduling of tanker liftings between the periods.
Impairment of oil and gas properties of $0.9 million for the six months ended June 30, 2006 represents the final abandonment and rig demobilization costs incurred on the Turriff well which was determined to be unsuccessful in the fourth quarter of 2005. All other costs for the Turriff well were included in impairments during the fourth quarter of 2005.
General and administrative (“G&A”) expenses increased to $5.3 million during the second quarter of 2006 as compared to $4.4 million for the corresponding period in 2005. G&A expenses increased to $10.7 million during the six months ended June 30, 2006 as compared to $8.5 million for the corresponding period in 2005. This increase was driven primarily by increases in compensation costs including non-cash stock-based compensation. Compensation costs increased as we increased operational, technical and financial staff to support our drilling program. Non-cash stock-based compensation increased as a result of the adoption of the fair value method of accounting for share-based payments effective January 1, 2006 and the issuance of additional stock-based compensation under the long-term incentive plan. Components of G&A expenses for these periods are as follows:

Interest expense increased to $2.3 million for the six months ended June 30, 2006 as compared to $2.0 million for the corresponding period in 2005 primarily due to the issuance of our convertible senior notes during the middle of the first quarter of 2005. The increase in cash generated as a result of the issuance of our convertible senior notes is also the primary reason for the increase in interest income to $1.2 million for the six months ended June 30, 2006.
Income Taxes
Our tax expense, relating solely to our Norwegian operations, of $6.8 million and $3.9 million for the six months ended June 30, 2006 and 2005, respectively, includes $1.9 million and $(1.2) million, respectively of foreign currency (gains) losses attributable to tax liability balances. For the six months ended June 30, 2006 and 2005, our Norwegian operations had income before taxes of $3.7 million and $7.3 million, respectively, as compared to a net income (loss) before taxes of $(10.4) million and $12.5 million, respectively, for us on a consolidated basis. During each of the periods presented for 2006 and 2005, we did not record any income tax benefits on our non-Norwegian operations as there was no assurance that we could generate any taxable earnings, and therefore recorded valuation allowances on the full amount of deferred tax assets generated. The gain from the sale of our partnership interests in 2005 were substantially offset by other current year tax losses in the U.S.
Our tax expense of $3.0 million and $2.9 million for the second quarter of 2006 and 2005, respectively, includes $1.2 million and $(0.4) million, respectively of foreign currency (gains) losses attributable to tax liability balances. For the second quarter of 2006 and 2005, our Norwegian operations had income before taxes of $1.2 million and $4.2 million, respectively, as compared to a net income (loss) before taxes of $(7.4) million and $14.1 million, respectively, for us on a consolidated basis.

Liquidity and Capital Resources
Cash flows used by operating activities were $13.9 million for the six months ended June 30, 2006 as compared to cash flows provided by operating activities of $9.3 million for the six months ended June 30, 2005 primarily due to lower revenues in 2006 resulting from the decreased production discussed above, higher interest expense in 2006 as discussed above and the changes in assets and liabilities between the two periods.
During the six months ended June 30, 2006, we have incurred approximately $21.3 million in exploration and development capital expenditures, primarily related to our drilling activities on the Cygnus well, final abandonment costs for the Turriff well, which was determined to be unsuccessful in the fourth quarter of 2005, and development expenditures on our producing fields in Norway and the Enoch field. During 2006, we also purchased the eight percent interest in the Enoch field for approximately $11.6 million. Exploration and development capital expenditures for the six months ended June 30, 2005 were $10.2 million which were primarily incurred in Norway since we did not begin drilling in the UK until the last half of 2005.
In addition, we sold our partnership interests in Thailand in April 2005 for net cash proceeds of approximately $19 million. Proceeds from the sale and capital expenditures originally targeted for Thailand were used to accelerate North Sea drilling activity in 2005.
In the first quarter of 2005, we issued $81.25 million in convertible senior notes due 2012. Interest expense on the senior notes is expected to be approximately $4.9 million annually and we anticipate being able to fund interest payments from cash flows from operating activities.
As previously discussed, we have a pending acquisition that will require significant financing. We are currently working to secure favorable terms for that financing and expect the transaction to close before the end of the year. The exact nature, terms and amounts of the various financing opportunities are still being determined.
Drilling Program
We currently anticipate exploration and development capital expenditures in 2006 to be approximately $42 million. It is expected that over $32 million of the 2006 capital program will be spent in the United Kingdom with the remaining $10 million spent in Norway. We may increase or decrease our planned activities for 2006 or pursue other attractive exploratory prospects, depending upon drilling results, potential acquisition candidates, product prices, the availability of capital resources, and other factors affecting the economic viability of such activities. In addition to the exploration and development budget, we invested $12 million for the purchase of an eight percent interest in the Enoch Field located in Block 16/13a in the North Sea during the second quarter of 2006.
Capital expenditures for 2006 reflect the continuation of our North Sea exploratory drilling program and development expenditures for existing operations in Norway and development drilling on the Enoch field. The first of our wells to begin drilling in 2006, the Cygnus well, was spud in early February 2006 in the UK sector of the North Sea. The well has successfully tested

as a gas discovery with significant potential upside. Operations at the site are being suspended following the completion of testing. It is expected that most of the key pre-development studies needed to facilitate a commerciality decision will be completed by the end of this year. Given a positive decision, it is anticipated that production could be initiated by the middle of 2008. The accumulation is located within close proximity to several potential transportation routes.
We also entered into a seismic acquisition contract for a proprietary 3-D survey covering 500 square kilometers on five blocks in the Inner Moray Firth acquired in the UK 23rd Seaward Licensing Round in 2005. Acquisition and processing should be completed by the end of the year in preparation for exploratory wells expected to be drilled in the area in 2007.
Rig Commitments
In the UK, we have a commitment for drilling services with a semi-submersible drilling rig for two wells beginning in the last half of 2006 for approximately $13.5 million. In the first quarter of 2006, we joined with several other operators in the Norwegian Continental Shelf to form a consortium that has entered into a contract for the use of a semi-submersible drilling rig for a three-year period beginning the second half of 2006. The agreement allows us to move forward with our exploration program in Norway and fulfill our role as an operator of Norwegian licenses. The contract commits us to 100 days (for two wells) of drilling services, for approximately $37.8 million, between late 2007 and 2008. We believe these rig-contracting efforts offer compelling economics and facilitate our drilling strategy.
During the second quarter of 2006, a wholly owned subsidiary entered into a rig commitment for 220 days over a one-year period beginning in March 2007 for the United Kingdom sector of the North Sea. The value of this contact is approximately $66 million. The arrangement with Applied Drilling Technology International, a division of GlobalSantaFe, will be for the GSF Magellan, a heavy-duty harsh environment jack-up suitable for most drilling activities the company will operate in 2007-2008.
As is common in the oil and gas industry, we operate in many instances through joint ventures under joint operating or similar agreements. Typically, the operator under a joint operating agreement enters into contracts, such as rig commitment contracts, for the benefit of all joint venture partners. Through the joint operating agreement, the non-operators reimburse, and in some cases advance, the funds necessary to meet the contractual obligations entered into by the operator. These obligations are typically shared on a “working interest” basis. The joint operating agreement provides remedies to the operator in the event that the non-operator does not satisfy its share of the contractual obligations. Occasionally, the operator is permitted by the joint operating agreement to enter into lease obligations and other contractual commitments that are then passed on to the non-operating joint interest owners as lease operating expenses, frequently without any identification as to the long-term nature of any commitments underlying such expenses.

Item 3: Quantitative and Qualitative Disclosures about Market Risk
Foreign Exchange Risk
The international scope of our business operations exposes us to the risk of fluctuations in foreign currency markets. As a result, we are subject to foreign currency exchange rate risk due to effects that foreign exchange rate movements of those currencies have on our costs and on the cash flows that we receive from foreign operations. We operate a centralized currency management operation to take advantage of potential opportunities to naturally offset exposures against each other. To date, we have addressed our foreign currency exchange rate risks principally by maintaining our liquid assets in interest-bearing accounts in U.S. dollars, until payments in foreign currency are required, but we have not reduced this risk by hedging to date.
Commodity Price Risk
We produce and sell crude oil and natural gas. Realized pricing is primarily driven by the prevailing worldwide price for crude oil and spot market prices applicable which has been volatile and unpredictable for several years. As a result, our financial results can be significantly impacted as these commodity prices fluctuate widely in response to changing market forces. We may engage in oil and gas hedging activities to realize commodity prices which we consider favorable.
See Note 5 to our Condensed Consolidated Financial Statements for a summary of our derivative instruments at June 30, 2006.
Interest Rate Risk
Our convertible senior notes bear interest at a fixed rate of 6%. We are exposed to changes in interest rates through the effect on interest earned on cash and cash equivalents. We do not currently use interest rate derivative financial instruments to manage exposure to interest rate changes, but may do so in the future.
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”), chief financial officer (“CFO”), and 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, CFO and CAO believe:
(i) that our disclosure controls and procedures are designed to ensure (a) that information we are required to disclose in our reports filed or submitted under the

Endeavour International Corporation
Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and (b) that such information is accumulated and communicated to our management, including the CEOs, CFO 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 change in our internal controls over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f), during the quarter ended June 30, 2006 that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.
