Note 1  General

Endeavour International Corporation (a Nevada corporation formed in 2000) is an independent oil and gas company engaged in the acquisition, exploration and development of energy reserves. Our goal is to become a leading upstream company
with an exploration focus primarily in the North Sea. We strive to achieve this position through acquisitions, licensing rounds and exploration drilling.

As used in these Notes to Condensed Consolidated Financial Statements, the terms Endeavour, we, us, our and similar terms refer to Endeavour International Corporation and, unless the context
indicates otherwise, its consolidated subsidiaries. The accompanying condensed consolidated financial statements of Endeavour and other information included in this Quarterly Report on Form 10-Q should be read in conjunction with our consolidated
financial statements and notes thereto included in our Annual Report on Form 10K for the year ended December 31, 2007.

Basis of
Presentation and Use of Estimates

The accompanying unaudited condensed consolidated financial statements have been prepared in accounting in
accordance with accounting principles generally accepted in the United States of America (US GAAP) and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes
required by US GAAP for complete financial statements, and have been presented on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. These accounting principles
require management to use estimates, judgments and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements, and revenues and expenses during the reporting period. Management reviews its
estimates, including those related to the determination of proved reserves, estimates of future dismantlement costs, income taxes and litigation. Actual results could differ from those estimates. In the opinion of management, all normal recurring
adjustments considered necessary for a fair presentation have been included in these financial statements. Certain amounts for prior periods have been reclassified to conform to the current presentation.

Management believes that it is reasonably possible that the following material estimates affecting our financial statements could change in the coming year:
(1) estimates of proved oil and gas reserves, (2) estimates as to our expected future cash flows from proved oil and gas properties, (3) estimates of future dismantlement and restoration costs, (4) estimates of fair values used
in purchase accounting and (5) estimates of the fair value of derivative instruments.

Income (Loss) Per Share

Basic income (loss) per common share is computed by dividing net income (loss) 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 preferred stock, convertible securities and certain stock incentive plans under the treasury stock method, if including these instruments would be
dilutive.

For the nine months ended September 30, 2008, 82.1 million common shares potentially issuable under our
warrants, convertible securities and certain stock incentive plans were excluded from diluted weighted average shares outstanding as their effects were anti-dilutive (i.e., increased the net income per share). For the three and nine months ended
September 30, 2007, 66.2 million common shares potentially issuable under our warrants, convertible securities and certain stock incentive plans were excluded from diluted weighted average shares outstanding as their effects were
anti-dilutive.

New Accounting Developments

In January 2008, we adopted two new interpretations issued by the Financial Accounting Standards Board. Both interpretations pertain to fair value measurement in financial reporting. The first interpretation defines fair value, outlines a
structure for measuring fair value and requires expanded financial statement disclosures about fair value measurements. It is applicable to all financial assets and liabilities that are being measured and reported on a fair value basis. The second
interpretation allows entities the option of fair value measurement for certain eligible financial instruments and other financial assets and liabilities. The results of our adoption and application of these standards are presented in Note 10.

In March 2008, the Financial Accounting Standards Board issued a new statement that requires expanded disclosures of
entities hedging activities and derivative instruments. This statement is effective for fiscal years and interim periods beginning after November 15, 2008. We are currently reviewing this new standard.

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 our option, however
it has been our practice to settle in stock. The restricted stock and options generally vest over three years and the options have a five year term. The vesting of these shares and options is dependent upon the continued service of the grantees to
Endeavour. Upon the occurrence of a change in control, each share of restricted stock and option outstanding on the date on which the change in control occurs will immediately vest. For the third quarter of 2008, we included non-cash stock-based
compensation of $0.8 million and $0.4 million in general and administrative expenses and capitalized general and administrative expenses, respectively. For the same period in 2007, we included non-cash stock-based compensation of $0.8 million and
$0.5 million in general and administrative expenses and capitalized general and administrative expenses, respectively. For the nine months ended September 30, 2008 and 2007, we included non-cash stockbased compensation of $1.5 million and
$2.7 million, in general and administrative expenses, respectively. For the nine months ended September 30, 2008 and 2007, we also included non-cash stockbased compensation of $0.9 million and $1.6 million in capitalized general and
administrative expenses, respectively. At September 30, 2008, total compensation costs related to nonvested awards not yet recognized was approximately $5.1 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 historical volatility of common stock prices of Endeavour and our peer companies where there is a lack
of relevant Endeavour volatility information for the length of the expected term. The expected term is the average of the vesting period and the term of the option. We use historical data to estimate option exercises and employee terminations within
the valuation model. The risk-free rate for the expected term is the yield on the zero-coupon U.S. treasury security with a term comparable to the expected term of the option. We do not include an estimated dividend yield since we have not
historically paid dividends on our common stock.

Restricted Stock

At September 30, 2008, our employees and directors held 3.8 million restricted shares of our common stock that vest over service periods 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. Compensation expense is recorded on a straight-line basis over the restricted share vesting period.

Convertible Bonds

In January 2008, we issued 11.5% Convertible Bonds due 2014 (the Convertible Bonds) for gross proceeds of $40 million pursuant to a private offering to a sophisticated investor in Norway. The net proceeds
from the issuance of the Convertible Bonds was used to repay a portion of our outstanding indebtedness.

The $40 million Convertible Bonds bear interest at
a rate of 11.5% per annum, compounded quarterly, and are unconditionally guaranteed by us on a senior unsecured basis. Interest is compounded quarterly and added to the outstanding principal balance each quarter. Interest is not payable in
cash, but is instead payable in kind upon maturity of the bonds. The bonds are convertible into shares of our common stock at an initial conversion price of $2.36 per $1,000 of principal. The conversion price will be adjusted in accordance with the
terms of the bonds upon occurrence of certain events, including payment of common stock dividends, common stock splits or issuance of common stock at a price below the then current market price.

Upon the fourth anniversary, the holders have the right to redeem the Convertible Bonds if the weighted average closing price of our common stock for the preceding 30
days is less than the conversion price, as adjusted. If the holders do not exercise this right, the right will lapse and the conversion price will be reset to the then current market price of our common stock if such price is lower than the
conversion price, as adjusted.

If we undergo a change of control as defined, the holders of the bonds have the right, subject to certain
conditions, to redeem the bonds and accrued interest. The bonds may become immediately due upon the occurrence of certain events of default, as defined.

Embedded derivatives

Two derivatives are associated with the conversion and change in control features of the Convertible
Bonds. At September 30, 2008, the combined fair market value of these derivatives is $15.3 million, reflecting a $6.3 million decrease during the third quarter that was recorded in other expense.

Junior Facility

We also borrowed $25 million under a
Junior Facility Agreement (the Junior Facility), dated January 22, 2008, bearing interest at LIBOR plus 3.5%. By September 30, 2008, we terminated the Junior Facility Agreement and repaid the outstanding indebtedness in its
entirety.

The costs not subject to amortization relate to unproved oil and gas 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. We capitalized $1.0 million and $1.6 million in interest related to exploration
activities for the quarters ended September 30, 2008 and 2007, respectively. For the nine months ended September 30, 2008 and 2007, we capitalized $3.2 million and $5.6 million, respectively, in interest related to exploration. We also
capitalized $3.0 million and $2.2 million in certain employee costs directly related to exploration activities for the quarters ended September 30, 2008 and 2007, respectively. We capitalized $7.2 million and $6.5 million in certain employee
costs directly related to exploration activities for the nine months ended September 30, 2008 and 2007, respectively. For the quarter ended September 30, 2008 and 2007, we included approximately $0.4 million and $0.5 million, respectively,
of stock-based compensation in capitalized G&A expenses in property and equipment.

Note 5  Derivative Instruments

Commodity derivatives

From time to time, we may utilize derivative financial instruments with respect
to a portion of our oil and gas production or a portion of our variable rate debt to achieve more predictable cash flows by reducing our exposure to price fluctuations. These transactions are likely to be swaps, collars or options and to be entered
into with major financial institutions or commodities trading institutions. Derivative instruments are intended to:



| |  |  | reduce our exposure to declines in the market prices of crude oil and natural gas that we produce and sell;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | reduce our exposure to increases in interest rates; and
| | - |  | -------------------------------------------------------



| |  |  | provide more stable cash flows in support of our annual capital expenditure budget.
| | - |  | -----------------------------------------------------------------------------------

We have various oil and gas derivative instruments intended to satisfy certain obligations under our financing agreements and to stabilize cash flows. Hedge accounting has not been elected for these instruments and
during the third quarter 2008 and 2007, we recorded $112.8 million and $(13.0) million in other income (expense) related to the net unrealized gains (losses) for these contracts. In addition, we realized $(13.6) million and $0.3 million in gains
(losses) on the settlement of instruments that closed during the third quarter of 2008 and 2007, respectively. The fair market value of these derivative instruments is included in our balance sheet as follows:

Note 9  Commitments and Contingencies

Rig Commitments

During 2008, we have held three long term rig commitments: (i) a heavy-duty harsh
environment jack-up rig in the UK, (ii) a semi-submersible rig in the UK and (iii) a semi-submersible rig in Norway. Each of these rig commitments is discussed below.

The heavy-duty harsh environment jack-up rig was originally contracted for 220 days. In 2007, we made a $22 million escrow payment under this commitment and utilized a portion of the commitment.

In March 2008, we entered into a $51.9 million agreement with Applied Drilling Technology International for use of a semi-submersible drilling rig in the UK during the
fourth quarter of 2008 and mid 2009.

During the third quarter of 2008, we applied the $22 million escrow toward the first of two drilling slots on the UK
semi-submersible rig and were released from the remaining term under the 220 day heavy duty jack-up commitment. This escrow payment is included in Restricted cash on our Condensed Consolidated Balance Sheet. We expect to utilize this
first rig slot during the fourth quarter of 2008 for the planned well at Rochelle.

(Unaudited)



The semi-submersible rig in Norway is contracted through a consortium, with several other operators in the Norwegian
Continental Shelf. The contract commits us to 100 days (for two wells) for drilling services for $38 million. We currently estimate the rig will be initially delivered in the second quarter of 2009 and again in the first quarter of 2010.

Contingencies

In November 2006, we purchased
various oil and gas properties, including the Ivanhoe, Rob Roy, Hamish (collectively, IVRRH), Renee and Rubie fields. Hess Limited, the operator of the facility supporting production from the IVRRH fields, has advised us that there has been a
mis-measurement of the volumes of oil produced from the IVRRH fields. During the third quarter of 2008, the estimate of our liability from this mis-measurement remained at $4.1 million. As the settlement of the mis-measurement liability is covered
under the purchase agreement for these assets, the increase in our net liability since December 31, 2007 was recorded as an increase to goodwill during the second quarter of 2008.

Note 10  Fair Value Measurements

Effective January 1, 2008, we adopted the new guidance for fair value
measurements of financial assets and liabilities measured on a recurring basis. This new standard defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market
participants at the measurement date. It also clarifies that fair value should be based on assumptions that market participants would use when pricing an asset or liability, including assumptions about risk and the risks inherent in valuation
techniques and the inputs to valuations. This includes not only the credit standing of counterparties involved and the impact of credit enhancements but also the impact of our own nonperformance risk on our liabilities. According to this new
standard, fair value measurements are classified and disclosed in one of the following categories:



|         |  |                                                                                                                                                                                                                                                                                                                                                                                                 
|-------- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|Level 1: |  | Fair value is based on actively-quoted market prices, if available.                                                                                                                                                                                                                                                                                                                             
|         | 
|Level 2: |  | In the absence of actively-quoted market prices, we seek price information from external sources, including broker quotes and industry publications. Substantially all of these inputs are
observable in the marketplace during the entire term of the instrument, can be derived from observable data, or supported by observable levels at which transactions are executed in the marketplace.
|         | 
|Level 3: |  | If valuations require inputs that are both significant to the fair value measurement and less observable from objective sources, we must estimate prices based on available historical and
near-term future price information and certain statistical methods that reflect our market assumptions.

We apply fair value measurements to certain assets and liabilities including commodity and interest rate derivative
instruments, marketable securities and embedded derivatives relating to conversion and change in control features in certain of our debt instruments. We seek to maximize the use of observable inputs and minimize the use of unobservable inputs when
measuring fair value.

Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value
measurement. The following table summarizes the valuation of our investments and financial instruments by pricing levels as of September 30, 2008:

Our commodity and interest rate derivative contracts were measured based on quotes from our counterparties, which
are major financial institutions or commodities trading institutions. Such quotes have been derived using models that consider various inputs including current market and contractual prices for the underlying instruments, quoted forward prices for
natural gas and crude oil, volatility factors and interest rates, such as a LIBOR curve for a similar length of time as the derivative contract term. The inputs for the fair value models for our swaps and Brent oil collars are all observable market
data and these instruments have been classified as Level 2. Although we utilize the same option pricing models to assess the reasonableness of the fair values of our gas collars, an active futures market does not exist for our UK gas options. We
base the inputs to the option models for our UK gas collars on observable market data in other markets to verify the reasonableness of the counterparty quotes. These UK gas collars are classified as Level 3.

|Item 2: | Managements Discussion and Analysis of Financial Condition and Results of Operations
|------- | -------------------------------------------------------------------------------------

Unless the context otherwise requires, references to 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 unaudited condensed consolidated financial statements and related notes thereto included elsewhere in this report and in our condensed consolidated financial
statements and related notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2007. The following discussion also includes non-GAAP financial measures, which may not be comparable to similarly titled measures
presented by other companies. Accordingly, we strongly encourage investors to review our financial statements in their entirety and not rely on any single financial measure.

Overview

We are an international oil and gas exploration and production company focused on the
acquisition, exploration and development of energy reserves. To date, we have invested a significant amount of our resources on various development, acquisition and exploration projects.

Oil prices continue to be impacted by supply and demand on a worldwide basis, while natural gas prices are more impacted by regional economic and weather patterns. Although oil prices have declined significantly in
recent weeks, natural gas prices in the UK and Norway have not experienced similar steep declines. Lower production volumes due to planned maintenance had a larger effect on our revenues for the third quarter than the falling oil prices as much of
the decline in prices occurred late in the quarter or after September 30, 2008. While we expect revenues to decline from third quarter 2008 to fourth quarter 2008 as a result of the sharp decline in oil prices, the full impact on our cash flows will
be substantially mitigated by our balance of gas to oil production and our commodity derivative positions. As of September 30, 2008, our outstanding commodity derivatives covered approximately 50% of our anticipated production for the remainder of
2008 and a substantial portion of expected 2009 production.

The worldwide credit and capital markets have recently exhibited adverse conditions. Continued
volatility in the credit and capital markets may increase costs associated with issuing debt instruments due to, among other things, increased spreads over relevant interest rate benchmarks and affect our ability to access those markets. At this
point, we do not believe our liquidity has been materially affected by the recent events in the global financial markets and we do not expect our liquidity to be materially impacted in the near future. We will continue to monitor our capital
requirements, the credit and capital markets and circumstances surrounding each of our lenders in our senior bank facility. To date we have experienced no disruptions in our ability to access additional funding through our senior facility. However,
we cannot predict with any certainty the impact to us of any further disruptions in the credit environment.

We believe the combination of cash on hand, cash flow from operations and our ability to time capital expenditures
allows us to manage volatile markets.

Results of Operations

As oil prices climbed to record levels and gas prices in our markets have recovered from last year, our realized price before derivatives increased 40% from the third quarter of 2007 to the third quarter of 2008. This
substantial increase in prices helped revenue grow from $121.6 million in the first nine months of 2007 to $219.1 million in the same period of 2008. With this higher revenue and strong fiscal discipline over expenses, we repaid $32.0 million in
debt, spent $46.5 million in capital expenditures during the first nine months of 2008 and increased cash from year end by $9.2 million. At September 30, 2008, we held $25.7 million in cash and another $22.0 million in cash restricted for
drilling rig commitments.

Even with the substantial growth in revenues, net income can be significantly affected by various non-cash items, such as
unrealized gains and losses on our commodity derivatives, currency impact of long-term liabilities and deferred taxes. Net loss to common stockholders for the first nine months of 2008 was $10.7 million, or $0.08 per share, reflecting the
significant unrealized loss on the mark-to-market of commodity derivatives. For the first nine months of 2007, net loss to common stockholders was $30.7 million, or $0.25 per share. The net loss for 2007 reflects a smaller unrealized loss on the
mark-to-market of commodity derivatives. Net income as adjusted for the nine months of 2008 would have been $6.6 million, or $0.05 per share without the effect of derivative transactions and currency impacts of deferred taxes as compared to net loss
as adjusted of $2.1 million, or $0.02 per share, in 2007. Net income and net income as adjusted for 2008 include $4.3 million in interest expense, including $2.1 million in cash, related to the early repayment of the Second Lien Term Loan. Adjusted
EBITDA increased to $142.9 million in 2008 from $89.0 million in 2007.

Discretionary cash flow was $105.1 million for the first nine months of 2008
compared to $79.4 million for the same period in 2007, reflecting the increase in revenues over the periods. Cash flows provided by operating activities increased to $99.6 million for the nine months ended September 30, 2008 as compared to
$95.2 million for the nine months ended September 30, 2007 primarily due to decreases in net cash provided by changes in operating assets and liabilities partially offset by higher commodity prices.

Given the significant impact that non-cash items may have on our net income, we use various measures in addition to net income, including non-financial performance
indicators and non-GAAP measures as key metrics to manage our business. These key metrics demonstrate the

companys ability to maintain or grow production levels and reserves, internally fund capital expenditures and service debt as well as provide
comparisons to other oil and gas exploration and production companies. These measures include, among others, debt and cash balances, production levels, oil and gas reserves, drilling results, discretionary cash flow, adjusted earnings before
interest, taxes, depreciation, depletion and amortization (Adjusted EBITDA) and adjusted net income.

For definitions of Adjusted EBITDA and
Discretionary Cash Flow, and a reconciliation of Adjusted EBITDA to net income as adjusted, please see Reconciliation of Non-GAAP Accounting Measures.

Revenues

Our revenues are sensitive to changes in prices received for our products. Our production is sold at prevailing
market prices which fluctuate in response to many factors that are outside of our control. Given the current tightly balanced supply-demand market, small variations in either supply or demand, or both, can have dramatic effects on prices we receive
for our oil and natural gas production. While the market price received for oil and natural gas varies among geographic areas, oil trades in a worldwide market, whereas natural gas, which has a limited global transportation system, is subject to
local supply and demand conditions. Consequently, price movements for all types and grades of crude oil generally move in the same direction, while natural gas price movements have historically followed local market conditions. The majority of our
natural gas is sold in the UK market. UK natural gas prices are influenced by European natural gas markets, liquefied natural gas (LNG) supply and new Norwegian gas supply. With the advent of more LNG facilities, natural gas price
movements will likely become more global in nature with a probable convergence of pricing between European and North American markets.

For the third
quarter of 2008 and 2007, we had sales volumes of 8,477 BOE per day and 9,713 per day barrels of oil equivalent (BOE), respectively. Sales volumes of 8,477 per day BOE reflect scheduled downtime at many of our fields to perform
planned maintenance activities during the third quarter of 2008. We record oil revenues on the sales method, i.e. when delivery has occurred. Physical production may differ based on the timing of tanker liftings. We use the entitlements method to
account for sales of gas production. During the nine months ended September 30, 2008 and 2007, we had sales volumes of 9,162 BOE per day and 9,205 BOE per day, respectively. We continue to expect full year 2008 production to range from 8,600 to
9,000 BOE per day.

During the nine months ended September 30, 2008, we realized $31.3 million in losses on the settlement of
our commodity derivatives, compared to $15.4 million in gains for the same nine month period in 2007. For the nine months ended September 30, 2008, we also recognized $41.2 million in losses on the mark-to-market of our commodity derivatives
that were not accounted for as hedges with $41.3 million in losses for the same period in 2007. In the third quarter of 2008, we realized $13.6 million in losses on the settlement of our commodity derivatives, compared to $0.3 million in gains for
the same period in 2007. In the third quarter of 2008, we also recognized $119.1 million in gains on the mark-to-market of our commodity derivatives with $13.0 million in losses for the same period in 2007.

Operating costs per BOE increased from $10.68 per BOE in the third quarter of 2007 to $13.98 per BOE in the third quarter of 2008, and from $11.93 per BOE
for the nine months ended September 30, 2007 to $13.90 per BOE for the nine months ended September 30, 2008. These increases were primarily due to higher operating costs at some of our non-operated fields.

General and administrative (G&A) expenses increased to $5.0 million during the third quarter of 2008 as compared to $4.1 million for the corresponding
period in 2007 but remained flat for the corresponding nine month periods. These decreases resulted from changes in non-cash stock-based compensation as a result of the final vesting of inducement grants given in 2004 upon the formation of Endeavour
and current year forfeitures. The decreases were partially offset by increases resulting from compensation expense, legal and tax consulting fees and occupancy costs. The compensation expense increase reflects additional payroll taxes and salary
expense related to increases in staffing. Occupancy costs increased due to additional rental space related to the staffing increase, while property acquisitions furthered the increase in legal and tax consulting fees. Components of G&A expenses
for these periods are as follows:

The increase in income tax expense from $1.8 million to $23.0 million for the first nine months of 2007 and 2008,
respectively, is primarily the result of increased revenues resulting from higher commodity prices and partially offset by the effect of foreign currency changes on our deferred tax liabilities.

In 2008 and 2007, we did not record any income tax benefits in the U.S. and certain other jurisdictions as there was no assurance that we could generate any taxable
earnings, resulting in a full valuation allowance of deferred tax assets generated.

As our deferred tax liabilities are denominated in their respective
currencies, we revalue those deferred tax liabilities to the applicable foreign currency exchange rate at the end of each period. Those foreign currency gains and losses are included in income tax expense as shown above.

Reconciliation of Non-GAAP Measures

Net Income (Loss) as Adjusted,
Adjusted EBITDA and Discretionary Cash Flow are internal, supplemental measures of our performance that are not required by, or presented in accordance with, generally accepted accounting principles (GAAP). We use these non-GAAP measures
as internal measures of performance and to aid in our budgeting and forecasting processes. We view these non-GAAP measures, and we believe that others in the oil and gas industry view these, or similar, non-GAAP measures, as commonly used analytic
indicators to compare

performance among companies. We further believe that these non-GAAP measures are frequently used by securities analysts, investors, and other interested
parties in the evaluation of issuers, many of which present these measures when reporting their results. We believe these non-GAAP measures provide useful information to both management and investors to gain an overall understanding of our current
financial performance and provide investors with financial measures that most closely align to our internal measurement processes. Since the application of mark-to-market accounting has the effect of pulling forward into current periods non-cash
gains and losses related to commodity derivatives relating to future delivery periods, analysis of results of operations from one period to another can be difficult. We believe that excluding these unrealized non-cash gains and losses related to
commodity derivatives and currency exchange changes provides a more meaningful representation of our economic performance in the reporting period and is therefore useful to us, investors, analysts and others in facilitating the analysis of our
results of operations from one period to another. These measures should not be considered as measures of financial performance under GAAP, and the items excluded from these measures are significant components in understanding and assessing financial
performance.

These non-GAAP measures should not be considered in isolation or as an alternative to net income, operating income, or any other performance
measures derived in accordance with GAAP or as alternatives to cash flows generated by operating, investing or financing activities as a measure of our liquidity. Because Net Income (Loss) as Adjusted, Adjusted EBITDA and Discretionary Cash Flow are
not measurements determined in accordance with GAAP and thus susceptible to varying calculations, Net Income (Loss) as Adjusted, Adjusted EBITDA and Discretionary Cash Flow as presented may not be comparable to other similarly titled measures of
other companies.

Net Income (Loss) as Adjusted, Adjusted EBITDA and Discretionary Cash Flow have limitations as analytical tools, and you should not
consider these measures in isolation, or as a substitute for analysis of our financial statement data presented in the consolidated financial statements as reported under GAAP. For example, Net Income (Loss) as Adjusted, Adjusted EBITDA and
Discretionary Cash Flow may not reflect:



| |  |  | our cash expenditures, or future requirements, for capital expenditures or contractual commitments;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | changes in, or cash requirements for, our working capital needs;
| | - |  | ----------------------------------------------------------------



| |  |  | unrealized gains (losses) on derivatives;
| | - |  | -----------------------------------------



| |  |  | non-cash foreign currency gains (losses);
| | - |  | -----------------------------------------



| |  |  | our interest expense, or the cash requirements necessary to service interest and principal payments on our debts;
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | our preferred stock dividend requirements; and
| | - |  | ----------------------------------------------



| |  |  | depreciation, depletion and amortization.
| | - |  | -----------------------------------------

Because
of these limitations, Net Income (Loss) as Adjusted, Adjusted EBITDA and Discretionary Cash Flow should not be considered as measures of cash available to us to invest in the growth of our business. We compensate for these limitations by relying
primarily on our GAAP results and by using Net Income (Loss) as Adjusted, Adjusted EBITDA and Discretionary Cash Flow only supplementally.

Liquidity and Capital Resources

Our main sources of liquidity and capital resources are internally generated cash flow from operations, a senior bank facility with both uncommitted and committed availability and access to both the debt and equity
capital markets. We believe that these sources of liquidity will be sufficient to meet our working capital requirements, anticipated capital expenditures (other than major capital improvements or acquisitions), scheduled debt payments and dividend
payments. Our ability to satisfy our obligations and planned expenditures will depend upon future operating performance, which will be affected by, among other things, prevailing economic conditions in the commodity markets of oil and natural gas,
some of which are beyond our control.

We have commodity derivative instruments to secure our realized prices for a portion of our oil and gas production
through 2011. We review the credit ratings our counterparties to derivative contracts (who are all lenders under our senior bank facility) on a regular basis and to date we have not experienced any non-performance by any of our counterparties. In
addition, much of our capital program is within our ability to control the timing of drilling and development expenditures. We intend to use a combination of cash on hand, debt capacity, derivative positions and timing of capital expenditures to
manage lower cash flows resulting from the recent decline in oil prices.

The following table summarizes our net cash flows from operating, investing and
financing activities for the periods indicated. For additional details regarding the components of our primary cash flow amounts, see the Condensed Consolidated Statements of Cash Flows.

The net cash flows provided by operating activities are primarily impacted by the earnings from our business
activities. The net cash flows provided by operating activities increased to $99.6 million for the nine months ended September 30, 2008 as compared to $95.2 million for the nine months ended September 30, 2007 primarily due to decreases in
cash flows provided by changes in net operating assets and liabilities, partially offset by higher commodity prices.

The net cash used in investing
activities represents expenditures for capital projects and asset purchases, as discussed in Drilling Program below, and increases to restricted cash under escrow for our rig commitments for 2007. The net cash used in financing
activities generally consists of borrowings and repayments of debt, proceeds from the issuance of equity securities and payment of financing costs.

In
January 2008, we completed the refinancing of certain debt with the following:



| |  |  | Repayment of the outstanding balance of $75 million under our Second Lien Term Loan, plus accrued interest;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | Issuance of $40 million under a private offering of 11.5% guaranteed convertible bonds to a company controlled by the Smedvig Family Office of Norway; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Issuance of $25 million under a Junior Facility Agreement (the Junior Facility).
| | - |  | ----------------------------------------------------------------------------------

The Convertible Bonds are unconditionally guaranteed by us on a senior unsecured basis. Interest is compounded quarterly and added to the outstanding principal balance
each quarter. Interest is not payable in cash, but is instead payable in kind upon maturity of the bonds.

We also borrowed $25 million under the Junior Facility. Amounts borrowed under the Junior Facility were repaid in
full by September 30, 2008.

Simultaneously with entering into the Junior Facility and issuing the Convertible Bonds, discussed above, we terminated
the Second Lien Term Loan and repaid all of the $78.6 million in outstanding indebtedness including accrued interest, related fees and expenses of approximately $4.3 million. The amount outstanding under the Second Lien Term Loan was scheduled to
mature in 2011.

Drilling Program

We originally
anticipated spending approximately $90 million during 2008 to fund oil and gas exploration and development in the North Sea. With delays in timing for delivery of the necessary drilling rigs, certain projects have been rescheduled for 2009. We
currently expect to spend $60 to $70 million in 2008, with $46.5 million spent through September 30, 2008. We intend to use a combination of cash available from operations and borrowings under our senior bank facility to fund the remainder of
our 2008 drilling program. The primary activity on exploration prospects and appraisal wells includes the following:

Norway

| |  |  | Galtvort (2.5% interest)  Drilling of Galtvort, a new field prospect, operated by StatoilHydro Petroleum AS, discovered gas. A sidetrack well was
drilled up-dip and encountered gas. Geologic evaluations of the data are continuing. As a result of a farm-out agreement with a private company, we are carried for all costs associated with the drilling of these well bores and will be carried on the
next exploration well and any sidetracks planned for 2009.

| |  |  | Noatun C (2.5% interest)  We encountered gas condensate at the discovery well and sidetrack at the Noatun C prospect. Noatun is a potential tieback to
the Njord field.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Brage North(4.4% interest)  A discovery at the Knockandoo prospect will begin production immediately upon completion from Brage field facilities.

United Kingdom



| |  |  | Rochelle (Operated, 55.6% interest)  An appraisal well is planned for the Rochelle discovery in which we hold a 55.6% interest. We will use our
existing commitment for a semi-submersible drilling rig in the fourth quarter of 2008 to drill this well.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Cygnus (12.5% interest)  We will drill an appraisal well in the Cygnus fault block IIb during the fourth quarter.
| | - |  | ------------------------------------------------------------------------------------------------------------------

The timing and order of this program will be determined by the completion of ongoing technical work, partner approvals and rig scheduling for individual prospects. We
may increase or decrease our planned activities for 2008 or high grade our 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. We believe we have a production base that generates significant cash flow to fund our future growth plans and ongoing operations.

In March 2008, we were awarded interests in two production licenses on the Norwegian Continental Shelf, a 15%
interest in PL453S and a 20% interest in PL457. Total acreage for the two awards approximates 538,000 acres, which brings our total acreage to 1,423,000 acres. We also entered into an agreement to farm down our interest in the Galtvort and Gygrid
prospects.

We submitted a Field Development Plan for governmental approval on the Columbus project in October 2008. The plan calls for a multi-phased
subsea tieback to link Columbus production to existing processing and pipeline facilities. First production is forecast to begin in the third quarter of 2010.

Rig Commitments

At September 20, 2008, we have long-term rig commitments for two rigs: a semi-submersible in the UK and one in Norway.
Each rig is committed for a two well program. We expect to utilize this first UK rig slot during the fourth quarter of 2008 for the planned well at Rochelle. We currently estimate the Norwegian rig will be delivered in the second quarter of 2009 and
in the first quarter of 2010.

2008 Outlook

We expect
production for 2008 to range from 8,600 to 9,000 BOE per day, with approximately 50%  55% of that production as gas. For 2008, we expect realized prices before derivatives to be $0.30 - $0.40 per Mcf less than the National Balance Point price
for gas and $4.00 - $5.00 per Bbl less than the Dated Brent price for oil. For the nine months ended September 30, 2008, our production averaged 9,200 BOE per day. According to the sales method of accounting, oil revenues are recognized when
production is sold to a purchaser at a fixed or determinable price, when delivery has occurred and title has transferred, and collectibility of the revenue is probable.

We expect operating costs per BOE to be in the range of $14 to $15 per BOE for 2008. Commodity prices can also affect our operating cash flow through an indirect effect on operating expenses. Commodity prices can also
affect our operating cash flow through an indirect effect on operating expenses. Significant commodity price increases, as experienced in recent years, can lead to an increase in drilling and development activities. As a result, the demand and cost
for people, services, equipment and materials may also increase, causing a negative impact on our cash flow.

|Item 3: | Quantitative and Qualitative Disclosures about Market Risk
|------- | ----------------------------------------------------------

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 regional gas spot market prices that have 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 that we consider favorable. For additional information regarding our derivative instruments, see Note 6 to the Condensed Consolidated Financial Statements.



|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, under the supervision and with the
participation of our chief executive officer (the CEO) and chief financial officer (the CFO), of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) and
15d-15(r) of the Securities Exchange Act of 1934, as amended). Based on that evaluation, the CEO and CFO concluded:

(i) that our disclosure
controls and procedures are designed to ensure that information we are required to disclose in our reports filed or submitted under the Securities Exchange Act of 1934, as amended, is (a) recorded, processed, summarized and reported within the
time periods specified in the SECs rules and forms, and (b) is accumulated and communicated to our management, including the CEO and CFO, as appropriate, to allow timely decisions regarding required disclosure; and

(ii) that our disclosure controls and procedures were effective as of September 30, 2008.

Changes in Internal Control over Financial Reporting

There was no change in our system of internal control over financial reporting during the last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

|Part II. | Other Information
|-------- | -----------------



|Item 1A: | Risk Factors
|-------- | ------------

In addition to the other information set forth in
this Form 10-Q, you should carefully consider the factors discussed in Item 1A Risk Factors, in our Annual Report on Form 10-K for the year ended December 31, 2007, which could materially affect our business, financial
condition or future results. The risks described in this Form 10-Q and in our Annual Report on Form 10-K are not the only risks facing our company. Additional risks and uncertainties not currently known to us or that we currently deem to be
immaterial also may materially adversely affect our business, financial conditions or future results.

Recent changes in the financial and credit
markets may impact economic growth, and a sustained decline of oil and natural gas prices can also affect our ability to obtain funding, obtain funding on acceptable terms or obtain funding under our current senior bank facility. This may hinder or
prevent us from meeting our future capital needs.

Global financial markets and economic conditions have been, and continue to be, disrupted and
volatile. The credit and capital markets have become exceedingly distressed. These issues, along with significant write-offs in the financial services sector, the re-pricing of credit risk and the current weak economic conditions have made, and will
likely continue to make, it difficult to obtain funding.

In addition, we may be unable to obtain adequate funding under our current senior bank facility
because (i) our lending counterparties may be unwilling or unable to meet their funding obligations or (ii) our borrowing base under our current senior bank facility is redetermined at least twice per year and may decrease as a result of
lower oil or natural gas prices, operating difficulties, declines in reserves, lending requirements or regulations, or for any other reason.

Due to these
factors, we cannot be certain that funding will be available if needed, and to the extent required, on acceptable terms. If funding is not available as needed, or is available only on unfavorable terms, we may be unable to meet our obligations as
they come due, or we may be unable to implement our development plan, enhance our existing business, complete acquisitions or otherwise take advantage of business opportunities or respond to competitive pressures, any of which could have a material
adverse effect on our production, revenues and results of operations.
