EXPLANATORY NOTE

     This Amendment No 1 to the Quarterly Report on Form 10-Q (the “Amended 10-Q”) of Quicksilver Resources Inc. (“Quicksilver” or the “Company”) for the three months ended March 31, 2009, originally filed on May 7, 2009 (the “Original Form 10-Q”), is being filed to correct certain footnote disclosures regarding amounts reported for Quicksilver’s guarantor and non-guarantor subsidiaries and to include disclosure of information for restricted subsidiaries that was not previously presented. The previously reported information was contained in Note 12 in the Original 10-Q. In Note 12 Condensed Consolidating Financial Information in Item 1 of this Amended 10-Q, Quicksilver has identified and corrected errors in the presentation of its guarantor and non-guarantor condensed consolidating financial information. Also, as previously disclosed in Note 6 Long-Term Debt, Quicksilver indicated that it was in compliance with its long-term debt, other notes and loans. Subsequent to the filing of the Original Form 10-Q, Quicksilver determined that financial information about the Company and its restricted subsidiaries should be included in the notes to the condensed consolidated financial statements pursuant to its supplemental indentures. Accordingly, Note 6 has been restated to reference the inclusion within Note 12 of the condensed consolidating financial information about the Company and its restricted subsidiaries.

     The Amended 10-Q also revises Management’s Discussion and Analysis of Financial Condition and Results of Operation in Item 2 to provide information about the Company and its restricted subsidiaries. Also, Item 4 Controls and Procedures has been amended to report the material weaknesses associated with the restatements described above. Part II. Item 1A. Risk Factors has also been updated.

     This Amended 10-Q does not alter or adjust the previously reported consolidated results of operation, financial position or cash flows for Quicksilver as reported in the Original Form 10-Q. Items previously reported in the Original Form 10-Q not affected by the error corrections have been omitted. The information in this Amended 10-Q reflects no events after May 7, 2009.

Forward-looking statements give our current expectations or forecasts of future events. Words such as “may,” “assume,” “forecast,” “position,” “predict,” “strategy,” “expect,” “intend,” “plan,” “estimate,” “anticipate,” “believe,” “project,” “budget,” “potential,” or “continue,” and similar expressions are used to identify forward-looking statements. They can be affected by assumptions used or by known or unknown risks or uncertainties. Consequently, no forward-looking statements can be guaranteed. Actual results may vary materially. You are cautioned not to place undue reliance on any forward-looking statements. You should also understand that it is not possible to predict or identify all such factors and should not consider the following list to be a complete statement of all potential risks and uncertainties. Factors that could cause our actual results to differ materially from the results contemplated by such forward-looking statements include:

• changes in general economic conditions;

• fluctuations in natural gas, NGL and crude oil prices;

• failure or delays in achieving expected production from exploration and development projects;

• uncertainties inherent in estimates of natural gas, NGL and crude oil reserves and predicting natural gas, NGL and crude oil reservoir performance;

• effects of hedging natural gas, NGL and crude oil prices;

• fluctuations in the value of certain of our assets and liabilities;

• competitive conditions in our industry;

• actions taken or non-performance by third parties, including suppliers, contractors operators, processors, transporters, customers and counterparties;

• changes in the availability and cost of capital;

• delays in obtaining oilfield equipment and increases in drilling and other service costs;

• operating hazards, natural disasters, weather-related delays, casualty losses and other matters beyond our control;

• the effects of existing and future laws and governmental regulations;

• the effects of existing or future litigation; and

• certain factors discussed elsewhere in this quarterly report.

     This list of factors is not exhaustive, and new factors may emerge or changes to these factors may occur that would impact our business. Additional information regarding these and other factors may be contained in our filings with the SEC, especially on Forms 10-K, 10-Q and
8-K. All such risk factors are difficult to predict, and are subject to material uncertainties that may affect actual results and may be beyond our control.

     All forward-looking statements are expressly qualified in their entirety by the foregoing cautionary statements.

NOTES TO CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS

UNAUDITED

1. ACCOUNTING POLICIES AND DISCLOSURES

     The accompanying condensed consolidated interim financial statements of Quicksilver Resources Inc. have not been audited. In the opinion of our management, the accompanying condensed consolidated interim financial statements contain all adjustments necessary to present fairly our financial position as of March 31, 2009 and our results of operations and cash flows for the three months ended March 31, 2009 and 2008. All such adjustments are of a normal recurring nature. The results for interim periods are not necessarily indicative of annual results.

     The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of certain assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during each reporting period. We believe our estimates and assumptions are reasonable, but actual results could differ from our estimates.

     Certain disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted. Accordingly, these financial statements should be read in conjunction with our consolidated financial statements and notes thereto included in our 2008 Annual Report on Form 10-K, as amended.

Earnings per Share

     The following is a reconciliation of the weighted average common shares used in the basic and diluted earnings (loss) per common share calculations for the three-month periods ended March 31, 2009 and 2008. The basic and diluted earnings (loss) per common share for each of the periods presented have been computed in compliance with guidance provided in Financial Staff Position (“FSP”) EITF 03-6-1. For additional information see Recently Issued Accounting Standards below. For the quarter ended March 31, 2009, approximately 10.2  million potentially dilutive securities, including 9.8 million for the convertible debentures, were excluded from the diluted net loss per share calculation as they were antidilutive. No potentially dilutive securities were excluded from the diluted net income per share calculation for the three-month period ended March 31, 2008.

Recently Issued Accounting Standards

• Pronouncements Impacting Quicksilver That Have Been Implemented

     SFAS No. 141 (revised 2007), Business Combinations, (“SFAS No. 141(R)”) was issued in December 2007. SFAS No. 141(R) replaces SFAS No. 141, Business Combinations, while retaining its fundamental requirements that the acquisition method of accounting be used for all business combinations and for an acquirer to be identified for each business combination. SFAS No. 141(R) defines the acquirer as the entity that obtains control in the business combination and it establishes the criteria to determine the acquisition date. The Statement also requires an acquirer to recognize the assets acquired and liabilities assumed measured at their fair values as of the acquisition date. In addition, acquisition costs are required to be recognized separately from the acquisition. SFAS No. 141(R) was further clarified by FSP FAS 141(R)-1, issued on April 1, 2009. FSP FAS 141(R)-1 addressed application issues regarding initial recognition and measurement, subsequent measurement and accounting, and disclosure of assets and liabilities arising from contingencies in a business combination. We will apply the Statement to any acquisition we enter into after January 1, 2009, but otherwise adoption had no effect on our financial statements.

     SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statements — an amendment of ARB No. 51 (“SFAS No. 160”) was issued in December 2007. The Statement amends prior standards to establish new accounting and reporting standards for the noncontrolling interest in a subsidiary (previously referred to as “minority interest”) and for the deconsolidation of a subsidiary. SFAS No. 160 clarifies that a noncontrolling interest in a subsidiary is an ownership interest in the consolidated entity that should be reported as a component of its equity. The Statement also changes the way the consolidated income statement is presented by requiring consolidated net income to be reported at amounts that include the amounts attributable to both the parent and noncontrolling interest. Additionally, SFAS No. 160 establishes a single method for accounting for changes in a parent’s ownership interest in a subsidiary that do not result in deconsolidation. We adopted this Statement on January 1, 2009, which resulted in the reclassification of the minority interest liability of $29.9 million and deferred tax benefit of $3.2 million, or $26.7 million to stockholders’ equity. Also, our adoption resulted in the reclassification of the $79.3 million deferred gain related to the KGS IPO to “paid in capital in excess of par value” within stockholders’ equity. Our consolidated balance sheet as of December 31, 2008 has been presented to conform to SFAS No. 160.

     In February 2008, the FASB issued FSP FAS 157-2, “Effective Date of FASB Statement No. 157” (“FSP FAS 157-2”), which granted a one-year deferral of the effective date of SFAS No. 157 as it applies to non-financial assets and liabilities that are recognized or disclosed at fair value on a nonrecurring basis (e.g. those measured at fair value in a business combination and asset retirement obligations). Beginning January 1, 2009, we applied SFAS No. 157 to non-financial assets and liabilities.

     The FASB issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities, (“SFAS No. 161”) in March 2008. SFAS No. 161 requires disclosures of the fair value of all derivative and hedging instruments and their gains or losses in tabular format and information about credit risk-related features in derivative agreements, counterparty credit risk, and its strategies and objectives for using derivative instruments. We adopted SFAS No. 161 on January 1, 2009 and the prescribed disclosures may be found in Note 3.

     In May 2008, the FASB issued FSP APB 14-1, “Accounting for Convertible Debt Instruments That May Be Settled in Cash upon Conversion (Including Partial Cash Settlement)” (“FSP APB 14-1”), which clarifies that convertible debt instruments that may be settled in cash upon conversion (including partial cash settlement) are not addressed by paragraph 12 of APB Opinion No. 14, “Accounting for Convertible Debt and Debt Issued with Stock Purchase Warrants.” In addition, FSP APB 14-1 indicates that issuers of such instruments generally should separately account for the liability and equity components in a manner that will reflect the entity’s nonconvertible debt borrowing rate when interest cost is recognized in subsequent periods. We adopted FSP APB 14-1 on January 1, 2009, which resulted in recognition of a $26.8 million addition to “paid in capital in excess of par value”, additional deferred tax liability of $5.8 million and decreases to other assets, long-term debt and retained earnings of $2.4 million, $19.0 million and $16.0 million, respectively. We have also presented all comparable prior period information in conformity with FSP APB 14-1.

     The FASB issued FSP EITF 03-6-1, “Determining Whether Instruments Granted in Share-Based Payments Transactions Are Participating Securities” (“FSP EITF 03-6-1”) in June 2008 and was effective and adopted by us on January 1, 2009. Under FSP EITF 03-6-1, unvested share-based payment awards that contain nonforfeitable rights to dividends (whether paid or unpaid) are participating securities and should be included in the computation of basic earnings per share pursuant to the two-class method. Based upon the characteristics of our equity awards, approximately 2.7 million restricted shares have been identified as participating securities and have been included in the basic earnings per share calculation for the three months ended March 31, 2009. Basic earnings per share for the quarter ended March 31, 2008 have been retrospectively adjusted to reflect approximately 1.1 million restricted shares as participating securities. Basic earnings per share for the quarter ended March 31, 2008 as adjusted were lowered by $0.01 for the combined effect of additional participating securities pursuant to FSP EITF 03-6-1 and by lower net income pursuant to adopting FSP APB 14-1.

     The following table summarizes the impact of implementing the accounting pronouncements:

     On April 9, 2009, the FASB issued FSP FAS 107-1 and APB 28-1, Interim Disclosures about Fair Value of Financial Instruments. This FSP amended SFAS No. 107, Disclosures about Fair Value of Financial Instruments, APB Opinion No. 28, Interim Financial Reporting, by requiring disclosures about fair value of financial instruments for interim reporting periods. The FSP also amended APB Opinion No. 28, Interim Financial Reporting, to require those disclosures in summarized financial information at interim reporting periods. We adopted the disclosures requirements under the FSP for the period ending March 31, 2009 as allowed by the FSP.

     FSP FAS 115-52 and FAS 124.2, Recognition and Presentation of Other-Than-Temporary Impairments, was also issued on April 9, 2009. This FSP amends the other-than-temporary impairment guidance for debt securities held as investments and presentation and disclosure of other-than-temporary impairments for such securities. We adopted this FSP for the quarter ended March 31, 2009, but it did not impact us.

     FSP FAS 157-4, Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly, (“FSP FAS 157-4”) was issued on April 9, 2009. FSP FAS 157-4 provides additional guidance for estimating fair value in instances when changes in the activity for a financial asset or liability have significantly decreased. We adopted FSP FAS 157-4 for the period ending March 31, 2009, which had no impact on fair value measurements at March 31, 2009.

• Pronouncements Not Yet Implemented

     The SEC adopted revisions to its required oil and gas reporting disclosures in December 2008. The revisions impacting us include: 1) use of 12-month average of the first-day-of-the-month prices for determination of proved reserve values included in calculating full cost ceiling limitations; 2) limitations on the types of technologies that may be relied upon to establish the levels of certainty required to classify reserves; and 3) ability to disclose “probable” and “possible” reserves as defined by the SEC. The SEC also updated the required disclosure requirements and eliminated use of price recoveries subsequent to period end for use in the ceiling test. We will adopt these changes effective on January 1, 2010 in accordance with the SEC’s transition rules and are still reviewing the implications of this adoption.

2. ALLIANCE ACQUISITION

     On August 8, 2008, Quicksilver completed the Alliance Acquisition, whereby the Company acquired leasehold, royalty and midstream assets associated with the Barnett Shale formation in northern Tarrant and southern Denton counties of Texas. The purchase price was funded as follows:

3. DERIVATIVES AND FAIR VALUE MEASUREMENTS

     We use derivatives to mitigate price risk associated with the sale of our natural gas, NGL and crude oil production. Prices for these products are capable of wide fluctuations that may negatively affect profitability and cash flow from operations. We mitigate the risk of adverse price movements through the use of swaps and collars, which also limits future gains from favorable price movements.

We enter into financial derivatives with counterparties who are generally lenders under our credit facility. The credit facility provides for collateralization of amounts outstanding from our derivative instruments in addition to amounts outstanding under the facility. Additionally, default on any of our obligations under derivative instruments with counterparty lenders could result in acceleration of the amounts outstanding under the credit facility. The credit facility and our internal credit policies require that any counterparties, including facility lenders, with whom we enter into commodity financial derivatives have credit ratings that meet or exceed BBB- or Baa3 from Standard and Poor’s or Moody’s, respectively.

     The estimated fair values of our derivatives of March 31, 2009 and December 31, 2008 are provided below. Derivatives are recorded in the balance sheet as current and non-current derivative assets and liabilities as determined by the expected timing of settlements. As of March 31, 2009, we had price collars or fixed price swaps hedging our anticipated natural gas production of approximately 190 MMcfd for the remainder of 2009. We have also hedged approximately 120 MMcfd of our anticipated 2010 natural gas production using natural gas price collars. In March 2009, we executed the early settlement of a price collar that hedged the sale of 40 MMcfd of our forecasted 2010 natural gas production. We received $54.9 million that had been previously recognized in AOCI. As natural gas is produced and sold during 2010, we will reclassify a portion of the settlement value from AOCI into natural gas revenue. Our gross derivative positions are presented as follows:

⁽¹⁾ Represents amounts netted under master netting arrangements with counterparties.

     The change in carrying value of our financial derivatives since December 31, 2008 principally resulted from the continued decline in market prices for natural gas relative to the prices in our derivative instruments partially offset by the $54.9 million early settlement of a natural gas collar that hedged the sale of 2010 natural gas production, and by monthly settlements received during the three months ended March 31, 2009.

     Gains and losses from the effective portion of derivative assets and liabilities held in AOCI that are expected to be reclassified to earnings over the next twelve months are $181.7 million net of income taxes. Gains from the effective portion of non-current derivative assets will be reclassified to earnings from AOCI over the nine months ending December 31, 2010. Hedge derivative ineffectiveness resulted in losses of $1.1 million and $5.5 million recorded in other revenue for the three months ended March 31, 2009 and 2008, respectively.

4. INVESTMENT IN BREITBURN ENERGY PARTNERS L.P.

     We own approximately 21.3 million common units of BBEP, a publicly traded limited partnership, which we acquired in connection with the BreitBurn Transaction. On June 17, 2008, BBEP announced that it had repurchased and retired 14.4 million units, which represented approximately 22% of the units previously outstanding. The resulting reduction in the number of BBEP common units outstanding increased our ownership from approximately 32% to approximately 41%.

     During the first quarter of 2009, we evaluated our investment in BBEP for impairment in response to further decreases in prevailing commodity prices and BBEP’s unit price since December 31, 2008. As a result of these decreases and the outlook for petroleum prices and broad limitations on available capital, we made the determination that the decline in value was other-than-temporary. Accordingly, our impairment analysis utilized the March 31, 2009 closing price of $6.53 per BBEP unit, which resulted in an aggregate fair value of $139.4 million for the portion of BBEP units owned by Quicksilver. The $139.4 million aggregate fair value was compared to an aggregate carrying value of $241.5 million. We recorded the difference of $102.1 million as a pre-tax impairment charge during the first quarter of 2009. Additional impairment of our investment in BBEP units could occur during the remainder of 2009 as BBEP suspended distributions to unitholders citing its intention to repay debt and reduce its aggregate borrowings and letters of credit below 90% of its borrowing base.

     We account for our investment in BBEP units using the equity method, utilizing a one-quarter lag from BBEP’s publicly available information. Summarized estimated financial information for BBEP is as follows:

	For the Three Months		For the Two Months
	Ended		Ended

Ceiling Test Analysis

     Under the full cost method in accounting for our oil and gas properties, we must perform a quarterly ceiling test for each of our cost centers. In determining the ceiling limitation, the ceiling test incorporates pricing, costs and discount rates over which management has no influence. Additionally, we do not include the benefits associated with our ownership and consolidation of KGS.

     The 2009 first quarter U.S. ceiling amount was computed using benchmark prices of $3.63 per Mcf of natural gas, $24.12 per barrel of NGL and $49.66 per barrel of crude oil. When we determined the present value of our U.S. reserves, the carrying value of our U.S. oil and gas properties exceeded the ceiling limit by $786.9 million (pre-tax). We computed the 2009 first quarter Canadian ceiling amount using a benchmark price of $2.92 per Mcf. Upon calculation of the present value of our Canadian reserves, the carrying value of our Canadian oil and gas properties exceeded the ceiling limit by $109.6 million (pre-tax). We recorded a total impairment charge of $896.5 million in the first quarter of 2009 as summarized below:

	Net				Pre-tax
	Capitalized		Ceiling		Charge for
	Costs (1)		Limitation (2)		Impairment
	(In thousands)
United States	$	2,727,130	$	1,940,263	$	786,867
Canada		458,135		348,519		109,616
Total	$	3,185,265	$	2,288,782	$	896,483

(1)

Net capitalized costs before impairment includes all costs associated with development, exploration and acquisition of oil and gas properties net of accumulated depletion and impairment, reduced by the related deferred income tax liability and asset retirement obligations.

(2)

The ceiling limitation is the sum of (i) estimated future net cash flows, discounted at 10% per annum, from proved reserves, based on unescalated period-end prices and costs, adjusted for asset retirement obligations and financial derivatives that hedge our oil and gas revenue, (ii) the costs of properties not being amortized, (iii) the lower of cost or market value of unproved properties not included in the costs being amortized, less (iv) income tax effects related to differences between book and tax bases of the oil and gas properties.

6. LONG-TERM DEBT (Restated)

     Except for issues arising from the failure to provide certain financial information about the Company and our restricted subsidiaries required to be disclosed under our supplemental indentures, as of March 31, 2009, we were in compliance with all covenants associated with our long-term debt, other notes and loans. On June 15, 2009, we completed receipt of acknowledgements from our lenders for the senior secured credit facility wherein they agreed to waive any defaults associated with the provision of financial information about the Company and our restricted subsidiaries. We believe that the provision of the financial information about the Company and our restricted subsidiaries herein and in our 2008 Annual Report on Form 10-K, as amended, satisfies the reporting requirements for all previous periods and requires no further waivers from our lenders, and accordingly have made no change to the anticipated maturities of the outstanding debt, as previously reported. Note 12 has also been restated to reflect inclusion of this financial information.

Long-term debt consisted of the following:

	March 31,			December 31,
	2009			2008
	(In thousands)
Senior secured credit facility	$	906,182		$	827,868

Less current maturities		(6,579	)		(6,579	)
Long-term debt	$	2,687,214		$	2,586,046

Senior Secured Credit Facility

     Approximately $283 million was available under the credit facility at March 31, 2009. In April 2009, the lenders affirmed our borrowing base at $1.2 billion and the interest spreads on our facility were revised upward.

Convertible Debentures

     The convertible debentures are contingently convertible into shares of Quicksilver common stock at a rate of 65.4418 shares for each $1,000 debenture, subject to adjustment. Upon conversion, we have the option to deliver any combination of Quicksilver common stock and cash. Should all debentures be converted to Quicksilver common stock, an additional 9,816,270 shares would become outstanding; however, as of April 1, 2009, the debentures were not convertible.

     On January 1, 2009, Quicksilver adopted FSP APB 14-1 as described in Note 1. The fair value of the equity component of our convertible debentures at the time of issuance was determined to be $26.8 million, net of deferred tax liabilities based upon an interest rate of 6.75%. The remaining unamortized discount on the debentures at December 31, 2008 was $20.8 million and $19.1 at March 31, 2009 and will be amortized through October 2011.

     For the quarters ending March 31, 2009 and 2008, interest expense on our convertible debentures was recognized at an effective interest rate of 6.75% was $2.4 million and $2.3 million, respectively. Previously, interest expense based on the coupon rate for the quarter ended March 31, 2008 had been $0.7 million for our convertible debentures and would have been the same amount for the quarter ended March 31, 2009. As of March 31, 2009, the carrying value of the $150 million convertible debentures was $130.9 million. The carrying value will be accreted to face value through October 2011.

KGS Credit Agreement

     At March 31, 2009, KGS’ borrowing capacity remained at the December 31, 2008 amount of $235 million, with $38.1 million of available capacity.

Quicksilver Stock Options

     Options to purchase shares of common stock were granted in 2009 with an estimated fair value of $8.7 million. We recognized expense of $1.2 million for stock options in the first three months of 2009. At March 31, 2009, we had unearned compensation cost of $10.7 million remaining, which will be recognized in expense through January 2011.

Wtd avg grant date fair value	$6.21
Wtd avg grant date	Jan 2, 2009
Wtd avg risk-free interest rate	1.90%
Expected life (in years)	6.0
Wtd avg volatility	56.8%
Expected dividends	—

12. CONDENSED CONSOLIDATING FINANCIAL INFORMATION (Restated)

     The following information reflects corrections to amounts previously reported. The previously reported information contained errors, most notably that combining adjustments for non-guarantor subsidiaries were reported as consolidating eliminations and certain earnings of consolidated non-guarantors were not appropriately reflected in their guarantor owners’ financial condition and results of operations. As more fully discussed in Note 6, we are also including financial information about the Company and our restricted subsidiaries.

     The following tables illustrate the effects of the errors on previously reported condensed consolidating financial information. These errors had no effect on either the condensed consolidating cash flows or on the consolidated amounts previously reported.

     The following tables provide information about the entities that guarantee our Senior Notes and our Senior Subordinated Notes. The guarantees are full and unconditional and joint and several. Under SEC rules, we are required to present financial information segregated between our guarantor and non-guarantor subsidiaries. The indentures under both our Senior Notes and the our Senior Subordinated Notes distinguish between “restricted” subsidiaries and “unrestricted” subsidiaries and further specify supplemental information that is not required under GAAP. Prior to August 2007, there was no unrestricted subsidiary that required provision of supplemental information in that none had both $10 million or more of net assets and assets that exceeded its liabilities by more than 5% of the amount by which our consolidated assets exceeded our consolidated liabilities. The following table illustrates our subsidiaries and their status pursuant to the Senior Notes and the Senior Subordinated Notes:

Guarantor Subsidiaries -	Non-Guarantor Subsidiaries
Restricted	Restricted	Unrestricted
Cowtown Pipeline Funding, Inc.	Quicksilver Resources Canada, Inc.	Quicksilver Gas Services Holdings LLC

	Beaver Creek Pipeline, LLC(1)	Cowtown Pipeline Partners L.P. (2)
	Quicksilver Resources Horn River Inc.	Cowtown Gas Processing Partners L.P. (2)
	Cowtown Drilling Inc.

(1)	Prior to the sale of the Northeast Operations in November 2007, these entities were restricted guarantor subsidiaries. After the sale, they have been reclassified to restricted non-guarantor subsidiaries for all periods presented.
(2)	Each entity is a wholly owned subsidiary of and consolidated into Quicksilver Gas Services LP.

     We own 100% of each of the restricted subsidiaries. We and the restricted subsidiaries conduct all of our exploration and production activities, and the unrestricted subsidiaries only conduct midstream operations. Neither the restricted non-guarantor subsidiaries nor the unrestricted non-guarantor subsidiaries guarantee the obligations under the Senior Notes and the Senior Subordinated Notes. However, the restricted non-guarantor subsidiaries, like the restricted guarantor subsidiaries, are limited in their activity by the covenants in the indenture for such matters as:

• incurring additional indebtedness;

• paying dividends;

• making investments; and

• making restricted payments.

     Subject to restrictions set forth in the indentures, we may in the future designate one or more additional subsidiaries as unrestricted.

The following is the financial information, as restated, and includes the financial information about the Company and our restricted subsidiaries:

ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

     The following discussion and analysis of our consolidated financial condition and results of operations should be read in conjunction with our condensed consolidated financial statements, and notes thereto, and the other financial data included elsewhere in this quarterly report. The following discussion should also be read in conjunction with our audited consolidated financial statements, and notes thereto, and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our 2008 Annual Report on
Form 10-K, as amended.

EXECUTIVE OVERVIEW

     We are an independent energy company engaged primarily in exploration, development and production of unconventional natural gas onshore in North America. We own producing oil and natural gas properties in the United States, principally in Texas, and in Alberta, Canada, where we had total estimated aggregate proved reserves of approximately 2.2 Tcfe of natural gas at December 31, 2008. We also have properties in the Horn River Basin of Northeast British Columbia and the Delaware Basin of West Texas where we are exploring for additional reserves, but have recognized no proved reserves. In addition, we own approximately 73% of KGS, a publicly traded midstream master limited partnership controlled by us, and we own approximately 41% of the limited partner units of BBEP, a publicly traded oil and natural gas exploration and production master limited partnership, which we account for using the equity method.

FIRST QUARTER AND OTHER 2009 HIGHLIGHTS

Increase in Production

     Daily production increased 57% during the three months ended March 31, 2009 from the corresponding period in 2008. The production increase is discussed further in Results of Operations below.

Amended Senior Secured Credit Facility

     On April 20, 2009, our bank group affirmed the borrowing base on our Senior Secured Credit Facility at $1.2 billion. The borrowing base is subject to annual and certain other redeterminations. The credit facility continues to provide for $1.2 billion of revolving credit commitments and we have the option to increase the facility to $1.45 billion with consent of the lenders. We can also extend the facility, which matures on February 9, 2012, up to two additional years with lender approval.

     In connection with affirming the borrowing base, Quicksilver and its bank group have amended the senior secured revolving credit facility to (i) increase the Eurodollar and specified rate margins from a range of 1.375% to 2.125% to a range of 2.25% to 3.25% (depending on the then-current borrowing base usage), (ii) increase the ABR margin from a range of 0% to 0.625% to a range of 1.375% to 2.375% (depending on the then-current borrowing base usage), (iii) add a floor to the ABR margin of one-month Libor plus 1%, and (iv) increase the unused commitment fee rate from a range of 0.25% to 0.375% to a flat rate of 0.5%. The margins across all grids will decrease by 0.25% upon full repayment of the Senior Secured Second Lien Facility.

Update on Horn River

     During the first quarter of 2009, we spent $29.3 million at our Horn River prospect where we have drilled a total of two wells. Our capital expenditures include costs related to infrastructure development, such as construction of roads. Also, we have reached an agreement with a third party that provides midstream services for the firm transportation of 3 MMcfd of natural gas out of the Horn River Basin with volumes increasing through May 2013 when the agreement allows transportation of up to 100 MMcfd. We expect that one of the wells drilled will commence production during the third quarter of 2009 with the second well commencing production during the fourth quarter of 2009.

BBEP Update

     On April 17, 2009, BBEP announced that its borrowing base under its credit facility had been reaffirmed, with no additional fees and no increase in borrowing rates, to be $760 million, which exceeded its then current borrowings of $717 million. Additionally, BBEP suspended its distributions to remain in compliance with certain provisions of its credit facility and to redirect cash flow to reduce its debt. BBEP management stated that the future resumption of distributions may be at levels below the recent distribution rate, but it cannot forecast or predict when distributions will resume. We have previously received quarterly distributions of $10 to $11 million.

OUTLOOK FOR REMAINDER OF 2009

     Commodity prices, drilling and well completion costs and access to capital are the most significant drivers of our business. As of the date of this quarterly report, the credit markets remain very tight and natural gas prices, both in the near-term and intermediate future, continue to experience downward pressure due to the global recession and the level of natural gas supply. As a result, we have reduced our 2009 capital program from $600 million to approximately $500 million, which we believe allows us to maintain flexibility and spend at or within our operating cash inflows for the year. We continue to focus primarily on the continued development of our properties in Texas and Alberta. For the remainder of 2009, we have allocated $160 million for exploration and development activities, $75 million for midstream facilities, including approximately $28 million to be funded directly by KGS and $5 million for other property and equipment. On a regional basis, approximately $220 million has been allocated to Texas to drill approximately 75 wells on operated properties and to complete and tie-in approximately 50 of those wells.

     Canada has been allocated $25 million to maintain current production levels through drilling of approximately 10 wells, completing approximately 20 wells, tie-in of approximately 30 wells and to continue the previously discussed exploratory activities in the Horn River Basin. The remaining capital budget is spread among our other operating areas.

     Our planned drilling program described above is dynamic and there are a number of factors that could impact our decisions to invest capital. Commodity prices, well costs, and program performance are a few factors that individually or in combination could change the scale or relative allocation of our capital program for 2009.

     The following table summarizes the changes in our production revenues during the quarter ended March 31, 2009 compared with the first quarter of 2008:

	Natural
	Gas			NGL			Oil			Total
	(In thousands)
Revenue for the quarter ended March 31, 2008	$	104,487		$	45,053		$	8,816		$	158,356
Volume changes		70,154			14,268			1,611			86,033
Price changes		(21,117	)		(33,925	)		(5,793	)		(60,835	)
Revenue for the quarter ended March 31, 2009	$	153,524		$	25,396		$	4,634		$	183,554

     Natural gas revenue increased as a result of a 99.1 MMcfd increase in production partially offset by a decrease in realized prices for the first quarter of 2009 as compared to the comparable 2008 period. Natural gas volumes for Texas increased 96.9 MMcfd from the properties purchased in the Alliance Transaction and from new wells placed into service in our other Fort Worth Basin properties subsequent to March 31, 2008. These increases were partially offset by natural production declines from existing Fort Worth Basin wells. Canadian natural gas production increased slightly as production from new wells placed into service subsequent to March 31, 2008 were almost entirely offset by natural declines of production from existing wells.

     The decrease in NGL revenue was due to a $28.23 per barrel decrease in realized prices for the first quarter of 2009 compared to the 2008 period. Partially offsetting the price decrease was a 3,359 Bbld production increase from the Fort Worth Basin due to new wells placed into production subsequent to the first quarter of 2008 and the improved NGL recoveries from the Corvette Plan, which was placed into service by KGS during the first quarter of 2009.

     Oil revenue for the first quarter of 2009 decreased due to a $43.03 per barrel decrease in realized prices for the first quarter of 2009 as compared to the 2008 period. A 243 Bbld increase in production for the first quarter of 2009 partially offset the impact of lower realized prices. Higher oil production was due to new wells placed into production subsequent to the first quarter of 2008.

     We expect our average production for the second quarter of 2009 to range from 330 MMcfed to 335 MMcfed.

Other Revenue

     Other revenue in the quarter ended March 31, 2009 increased $3.1 million from the comparable 2008 quarter. The increase was primarily due to a $4.4 million reduction in losses resulting from partial ineffectiveness of the derivatives hedging our Canadian production for the first quarter of 2009 as compared to the 2008 first quarter, which was offset by slight decreases in revenue from marketing and transition services provided during the first quarter of 2008.

     Production expense was virtually unchanged primarily because of cost containment efforts in the Fort Worth Basin during the first quarter of 2009 when compared to the first quarter of 2008 despite higher production levels. As discussed above, our daily production from the Fort Worth Basin increased approximately 82% while production expense increased only $1.0 million when comparing the first quarter of 2009 to the 2008 first quarter. Fort Worth Basin production expense per Mcfe for the first quarter of 2009 decreased 42% from the first quarter of 2008. First quarter Fort Worth Basin production expense of $0.98 per Mcfe also reflected a 10% decrease from $1.09 per Mcfe for the fourth quarter of 2008. These decreases resulted from ongoing stringent efforts to contain costs through vendor bidding processes, bulk purchasing and additional reliance on automation.

     Canadian production expense for the first quarter of 2009 decreased $1.8 million, or $0.35 per Mcfe, from the first quarter of 2008. Decreased Canadian production expense was primarily the result of favorable changes in U.S.-Canadian exchanges rates for the first quarter of 2009 when compared to the first quarter of 2008. Canadian production expense on a Canadian dollar basis increased approximately C$0.7 million.

     First quarter 2009 production and ad valorem taxes increased $1.7 million when compared to the first quarter of 2008. The addition of wells and midstream facilities in the Fort Worth Basin over the past twelve months increased ad valorem taxes approximately $2.3 million from the first quarter of 2008 to the first quarter of 2009.

Total depletion, depreciation and accretion	$	59,696	$	2.00	$	35,059	$	1.82

     Higher depletion for the first quarter of 2009 was due primarily to an increase in both production and the depletion rate. Our U.S. depletion expense increased due primarily to a 79% increase in U.S. sales volumes. The lower depletion rate for our Canadian properties reflects favorable changes in the U.S.-Canadian dollar exchange rate and the maturity of our Canadian properties. The improvement in the exchange rate decreased depletion $0.6 million when comparing the first quarter of 2009 to the 2008 first quarter. The $2.9 million increase in U.S. depreciation for the first quarter of 2009 as compared to the 2008 first quarter was primarily associated with additions of Fort Worth Basin field compression and KGS’ gathering system in addition to KGS’ Corvette Plant that was placed into service in the first quarter of 2009. After recognition of the impairment charge (described more fully below), we expect our depletion expense on a Mcfe-basis to decrease 20% to 25% for the remainder of 2009.

Impairment of Oil and Gas Properties

     We recognized a non-cash pre-tax charge of $896.5 million ($593.7 million after tax) for impairment related to both our U.S. and Canadian oil and gas properties in March 2009. Benchmark natural gas prices at March 31, 2009 for the U.S. and Canada decreased $2.08 per Mcf and $2.52 per Mcf, respectively, from December 31, 2008 and resulted in significant decreases to the future net cash flows from our proved oil and gas reserves. As required under full cost accounting rules, we performed a ceiling test by comparing the book value of our oil and gas properties, net of related deferred tax liability and asset retirement obligations, to the period-end ceiling limitation, which is the after-tax value of the future net cash flows from proved oil and gas reserves, including the effect of hedges. As also required under full cost accounting rules prescribed by the SEC, the ceiling amount was based upon period-end prices and costs held constant into the future, discounted at 10% per year. See Note 5 to our condensed consolidated financial statements for more information.

Total general and administrative expense	$	17,381	$	0.58	$	15,415	$	0.80

     General and administrative expense for the first quarter of 2009 increased from the comparable 2008 period due a $1.6 million increase for the vesting of stock-based compensation and $0.8 million for all other employee compensation and benefits. Expenses for legal fees increased general and administrative expense by approximately $1.4 million for the first quarter of 2009 as compared to the 2008 first quarter, and were associated with various corporate legal matters including our litigation with BBEP.

BBEP-Related Income and Expense

     During the first quarter of 2009, we recognized $102.1 million for equity earnings from our investment in BBEP for the fourth quarter of 2008 as compared to $6.2 million for the two-month period ending December 31, 2007. A portion of the increase in equity earnings is the result of an increase in our proportionate ownership of BBEP from 32% to 41% as a result of BBEP’s purchase and retirement of units in June 2008 while the remaining increase is primarily from large unrealized gains from its derivative instruments. BBEP continues to experience significant volatility in its net earnings due to changes in value of its derivative instruments for which it does not employ hedge accounting.

     During the first quarter of 2009, we reevaluated our investment in BBEP for impairment in response to further decreases in prevailing commodity prices and BBEP’s unit price since December 31, 2008. As a result of these decreases and the outlook for petroleum prices and broad limitations on available capital, we made the determination that the decline in value was other-than-temporary. Accordingly, our impairment analysis utilized the March 31, 2009 closing price of $6.53 per BBEP unit, which resulted in an aggregate fair value of $139.4 million for the portion of BBEP units owned by Quicksilver. The $139.4 million aggregate fair value was compared to the $241.5 million carrying value of our investment in BBEP. We recorded the difference of $102.1 million as an impairment charge during the first quarter of 2009. We believe that additional impairment of our investment in BBEP units may occur during the remainder of 2009 as BBEP suspended distributions to unitholders citing its intention to repay debt and reduce its aggregate borrowings and letters of credit below 90% of its borrowing base. See Note 4 to our condensed consolidated financial statements for more information.

Interest expense	$	40,201		$	13,435

     Interest costs for the first quarter of 2009 were higher than the 2008 first quarter primarily because of the issuance of our 2015 Senior Notes and our Senior Secured Second Lien Facility in June and August of 2008, respectively, as well as additional borrowings outstanding under our Senior Secured Credit Facility. We expect interest expense to increase during future quarters based on increases to base borrowing rates, announced as part of the affirmation of our borrowing base under our Senior Secured Credit Facility, and by a decrease in the amount of interest costs capitalized after placing the Corvette Plant into service.

     Our provision for income taxes for the first quarter of 2009 decreased from the prior-year period due to a $296.8 million decrease in U.S. income tax expense and a $24.3 million decrease in Canadian income tax associated with lower pre-tax earnings that were primarily the result of impairment charges for our oil and gas properties recognized during the 2009 first quarter. The effective tax rate for the 2009 first quarter was most significantly affected by the resulting taxable net loss in both the U.S. and Canada that will be taxed at approximately 35% and approximately 25%, respectively. We expect our effective income tax rate to be in a range from 34% to 35% for all of 2009.

Quicksilver Resources Inc. and its Restricted Subsidiaries

     The indentures under both our Senior Notes and our Senior Subordinated Notes distinguish between “restricted” subsidiaries and “unrestricted” subsidiaries. Our unrestricted subsidiaries consist of:

• Quicksilver Gas Services Holdings LLC;

• Quicksilver Gas Services GP LLC;

• Quicksilver Gas Services LP;

• Quicksilver Gas Services Operating LLC;

• Quicksilver Gas Services Operating GP LLC;

• Cowtown Pipeline Partners L.P.; and

• Cowtown Gas Processing Partners L.P.

     All of our other subsidiaries are restricted subsidiaries (collectively, the “Restricted Subsidiaries”). The Company and its Restricted Subsidiaries conduct all of our exploration and production activities, where as the “unrestricted subsidiaries” conduct only midstream operations.

     The combined results of operations for the Company and its restricted subsidiaries are substantially similar to our consolidated results of operations, which are discussed above under “Results of Operations”. The combined financial position of the Company and its restricted subsidiaries and our consolidated financial position are materially the same except for the property, plant and equipment purchased by the unrestricted subsidiaries since the KGS IPO, the borrowings under the KGS credit facility and the equity of the unrestricted subsidiaries. The other balance sheet items are discussed below in “Financial Position.” The combined operating cash flows, financing cash flows and investing cash flows for the Company and its restricted subsidiaries are substantially similar to our consolidated operating cash flows, financing cash flows and investing cash flows, which are discussed below in “Liquidity, Capital Resources and Financial Position.” Further information regarding the Company, our restricted subsidiaries and our unrestricted subsidiaries is included in Item 1 of this Report.

LIQUIDITY, CAPITAL RESOURCES AND FINANCIAL POSITION

Cash Flow Activity

     Our financial condition and results of operations, including our liquidity and profitability, are significantly affected by the prices that we realize for our natural gas, NGL and oil production and the volumes of natural gas, NGL and oil that we produce.

     The natural gas, NGL and oil that we produce are commodity products for which established trading markets exist. Accordingly, product pricing is determined by the relationship between supply and demand for these products in the relevant markets. Product supply is affected primarily by fluctuations in production volumes, and product demand is affected by the state of the economy in general, the availability and price of alternative fuels and a variety of other factors. Prices for our products historically have been volatile, and we have no meaningful influence over the timing and extent of price changes for our products. Although we have mitigated our near term exposure to such price declines through the use of derivative financial instruments covering substantial portions of our expected near-term production, we cannot confidently predict whether or when market prices for natural gas, NGL and oil will increase or decrease.

     The volumes that we produce may be significantly affected by the rates at which we acquire leaseholds and other mineral interests and explore, exploit and develop our leaseholds and other mineral interests through drilling and production activities. These activities require substantial capital expenditures, and our ability to fund these activities through cash flow from our operations, borrowings and other sources may be significantly affected by both the continued turmoil in the credit and financial markets, resulting in us and other industry participants announcing reductions year-over-year in planned levels of capital expenditures and drilling activities for the remainder of 2009.

Effect of exchange rate changes in cash		(224	)		(474	)

     Operating Cash Flows

     Net cash provided by operations in the first quarter of 2009 increased compared to the first quarter of 2008 primarily due to significantly higher production from our Texas oil and gas properties partially offset by lower average realized natural gas, NGL and crude oil prices. Additionally, the early settlement of a derivative hedging 40 MMcfd of 2010 natural gas production provided $54.9 million of operating cash flow. Working capital otherwise decreased $13.6 million in the first quarter of 2009. Furthermore, our 2009 first quarter receipt of cash distributions on our BBEP units increased $1.4 million from the first quarter of 2008 to $11.1 million. BBEP subsequently announced in April 2009 that it was suspending its distributions to its unitholders.

     For the quarter ended March 31, 2009, price collars and swaps covered approximately 78% of our natural gas production and resulted in higher realized revenues from our production of $53.9 million. As of March 31, 2009, we had price collars or fixed price swaps hedging our anticipated natural gas production of approximately 190 MMcfd for the remainder of 2009. We have also hedged approximately 120 MMcfd of our anticipated sale of 2010 natural gas production using natural gas price collars. We recorded the receipt of the $54.9 million settlement of the previously discussed 40 Mmcfd contract in AOCI. As natural gas is produced and sold during 2010, we will reclassify the proportionate amount of the settlement into natural gas revenue.

     In April 2009, we received a U.S. federal income tax refund of $41.1 million attributable to the taxable loss generated during 2008 in the U.S. This amount was included in accounts receivable as of March 31, 2009.

     Investing Cash Flows

     Our expenditures for property and equipment (payments for property and equipment plus non-cash changes in working capital associated with property and equipment) during the first quarter of 2009 totaled $198.8 million as detailed below.

     During the first quarter of 2009, we paid $256 million for property and equipment, a decrease of approximately $76 million from the 2008 period.

     Financing Cash Flows

     As of March 31, 2009, approximately $283 million was available for borrowing under our Senior Secured Credit Facility. We were in compliance with all covenants under our debt agreements at March 31, 2009. In April 2009, the lenders affirmed our borrowing base at $1.2 billion and the spreads on our facility were revised upward. Please see First Quarter and Other 2009 Highlights on page 23 for additional information.

     KGS’ $235 million senior secured credit facility had $196.9 million of borrowings outstanding and KGS was in compliance with all of its covenants at March 31, 2009.

     As of March 31, 2009 and December 31, 2008, we had the following total capitalization:

     We currently anticipate that remaining 2009 capital expenditures of approximately $250 million will be funded from operating cash inflows.

Financial Position

     The following impacted our balance sheet as of March 31, 2009, as compared to our balance sheet as of December 31, 2008:

• Our current derivative assets increased $89.5 million while our deferred derivative assets decreased $34.0 million as a result of higher derivative valuations partially offset by monthly settlements of $53.9 million, and the early settlement of a derivative hedging a portion of our 2010 production for $54.9 million. Our derivative liabilities decreased $9.1 million as a result of the Michigan Sales Contract expiring on March 31, 2009. Our current

	deferred income tax liability increased $37.6 million as a result of an overall increase in the valuations of our derivatives.
•	Our net property, plant and equipment balances decreased $785 million as a result of charges for impairment of our oil gas properties of $896.5 million and DD&A expense of $59.7 million partially offset by $198.8 million of costs incurred for property, plant and equipment.
•	Our deferred income tax liability decreased $199.3 million and a deferred tax asset of $108.8 million was reclassified in connection with the impairment of both our investment in BBEP and our oil and gas properties.

Contractual Obligations and Commercial Commitments

     There have been no significant changes to our contractual obligations and commercial commitments as disclosed in Item 7 in our 2008 Annual Report on Form 10-K, as amended.

Critical Accounting Estimates

     Management’s discussion and analysis of financial condition and results of operations are based on our condensed consolidated interim financial statements and related footnotes contained within this report. Our more critical accounting estimates used in the preparation of the consolidated financial statements were discussed in our 2008 Annual Report on Form 10-K, as amended. These critical estimates, for which no significant changes occurred during the three months ended March 31, 2009, include estimates and assumptions for:

• full cost ceiling calculation;

• oil and gas reserves;

• derivative instruments;

• asset retirement obligations;

• stock-based compensation; and

• income taxes.

     The process of preparing financial statements in conformity with GAAP requires the use of estimates and assumptions to determine certain of the assets, liabilities, revenues and expenses. These estimates and assumptions are based upon what we believe is the best information available at the time of the estimates or assumptions. The estimates and assumptions could change materially as conditions within and beyond our control change. Accordingly, actual results could differ materially from those estimates.

Off-Balance Sheet Arrangements

     We have no off-balance sheet arrangements within the meaning of Item 303(a)(4) of SEC Regulation S-K.

Recently Issued Accounting Standards

     The information regarding recent accounting pronouncements is included in Note 1 to our condensed consolidated financial statements included in Item 1 of this quarterly report.

ITEM 4. Controls and Procedures

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

     We carried out an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report pursuant to Securities Exchange Act Rule 13a-15. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of March 31, 2009, our disclosure controls and procedures were not effective to provide reasonable assurance that material information required to be disclosed by us (including our consolidated subsidiaries) in reports that we file or submit under the Securities Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that information required to be disclosed by us in the reports we file or submit under the Securities Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

     As disclosed in our 2008 Annual Report on Form 10-K, as amended, we identified material weaknesses relating to:

• Preparation and review of combined financial information within our condensed consolidating financial information. The condensed consolidating information previously reported contained errors that resulted from inadequate review of the combined financial information. These errors did not affect the amounts previously reported in our consolidated financial statements.

• Monitoring the Company’s financial reporting requirements. The review associated with the completeness of the required information failed to highlight omitted information related to the Company and its restricted subsidiaries.

Changes in Internal Control Over Financial Reporting

     In response to the identification of these material weaknesses, management has revised its process to better structure the preparation and allow for further review of its consolidating financial information. Further, management has enhanced its process for documenting and satisfying the full extent of the Company’s financial reporting requirements. Management believes that these enhancements and improvements, when repeated in future periods, remediate the material weaknesses described above.

     Other than the identification and remediation plans for the material weaknesses described above, there has been no change in our internal control over financial reporting during the quarter ended March 31, 2009 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. Other Information

     As further discussed in Note 12 (Restated) to our condensed consolidated financial statements in Item 1 of this Report, we have restated certain guarantor and non-guarantor financial information previously reported and have included information about the Company and its restricted subsidiaries, and the following risk factors have been updated to reflect risks associated therewith.

Item 1A. Risk Factors

     The following risk factors update the risk factors set forth in Part I, Item IA, “Risk Factors” of our 2008 Annual Report on Form 10-K, as amended. You should carefully consider the following risk factors together with all of the other information included in this quarterly report and the other information that we file with the SEC, including the financial statements and related notes, when deciding to invest in us. You should be aware that the occurrence of any of the events described in this Risk Factors section and elsewhere in this quarterly report could have a material adverse effect on our business, financial position, results of operations and cash flows.

Natural gas, NGL and crude oil prices fluctuate widely, and low prices could have a material adverse impact on our business, financial condition, results of operations and cash flows.

     Our revenue, profitability and future growth depend in part on prevailing natural gas, NGL and crude oil prices. These prices also affect the amount of cash flow available to service our debt, pay for our capital expenditures and fund our other liquidity needs, as well as our ability to borrow, raise additional capital and comply with the terms of our debt agreements. Among other things, the amount we can borrow under our Senior Secured Credit Facility is subject to periodic redetermination based in part on changing expectations of future prices. Lower prices may also reduce the amount of natural gas, NGLs and crude oil that we can economically produce.

     While prices for natural gas and crude oil may be favorable at any point in time, they fluctuate widely, particularly as evidenced by price movements in the latter half of 2008 and the first quarter of 2009. Among the factors that can cause these fluctuations are:

• domestic and foreign demand for natural gas and crude oil;

• the level of domestic and foreign natural gas and crude oil supplies;

• the price and availability of alternative fuels;

• weather conditions;

• domestic and foreign governmental regulations;

• impact of trade organizations, such as OPEC;

• political conditions in oil and natural gas producing regions; and

• worldwide economic conditions.

     Due to the volatility of natural gas and crude oil prices and our inability to control the factors that influence them, we cannot predict future pricing levels.

If natural gas, NGL or crude oil prices decrease, our exploration and development efforts are unsuccessful or our costs increase substantially, we may be required to recognize impairment of our oil and gas properties, which could have a material adverse effect on our financial condition, our results of operations and our ability to borrow under and comply with our debt agreements.

     We employ the full cost method of accounting for our oil and gas properties, whereby all costs associated with acquiring, exploring for, and developing natural gas and crude oil reserves are capitalized and accumulated in separate country cost centers. These capitalized costs are amortized based on production from the reserves for each country cost center. Each capitalized cost pool cannot exceed the net present value of the underlying natural gas, NGL and crude oil reserves. Impairment to the carrying value of our oil and gas properties was recognized in both the fourth quarter of 2008 and the first quarter of 2009 and could occur again in the future if natural gas, NGL or crude oil prices at a reporting period end result in decreased value of our reserves. Increased operating and capitalized costs without incremental increases in natural gas and crude oil reserves could also trigger impairment based on decreased value of our reserves. In the event of impairment of our oil and gas properties, we reduce their carrying value and recognize expense in the amount of the impairment, which could be material and could adversely affect our financial condition and results of operations and our ability to borrow under and comply with the terms of our debt agreements.

Reserve estimates depend on many assumptions that may turn out to be inaccurate and any material inaccuracies in these reserve estimates or underlying assumptions may materially affect the quantities and present value of our reserves.

     The process of estimating natural gas, NGL and crude oil reserves is complex. It requires interpretations of available technical data and various assumptions, including assumptions relating to economic factors. Any significant inaccuracies in these interpretations or assumptions could materially affect the estimated quantities and present value of reserves disclosed in our filings with the SEC.

     In order to prepare these estimates, we and independent reserve engineers engaged by us must project production rates and timing of development expenditures. We and the engineers must also analyze available geological, geophysical, production and engineering data, and the extent, quality and reliability of this data can vary. The process also requires economic assumptions with respect to natural gas and crude oil prices, drilling and operating expenses, capital expenditures, taxes and availability of funds. Therefore, estimates of natural gas, NGL and crude oil reserves are inherently imprecise.

     Actual future production, natural gas, NGL and crude oil prices and revenue, taxes, development expenditures, operating expenses and quantities of recoverable natural gas and crude oil reserves most likely will vary from our estimates. Any significant variance could materially affect the estimated quantities and present value of reserves disclosed in our Annual Report on Form 10-K, as amended. In addition, we may adjust estimates of proved reserves to reflect production history, results of exploration and development, prevailing petroleum prices and other factors, which may be beyond our control.

     At December 31, 2008, approximately 37% of our estimated proved reserves were undeveloped. Undeveloped reserves, by their nature, are less certain than comparable developed reserves. Recovery of undeveloped reserves requires additional capital expenditures and successful drilling and completion operations. Our reserve data assumes that we will make significant capital expenditures to develop our reserves. Although we have prepared estimates of our reserves and the costs associated with them in accordance with industry standards, there is risk that the estimated costs are inaccurate, that development will not occur as scheduled or that actual results will not be as estimated.

     The present value of future net cash flows disclosed in Item 8 of our Annual Report on Form 10-K, as amended, is not necessarily the fair value of our estimated proved natural gas and crude oil reserves. In accordance with SEC requirements, the estimated discounted future net cash flows from proved reserves are based on prices and costs as of period end. Actual future prices and costs may be materially higher or lower than the prices and costs as of the date of the estimate. Any changes in consumption by natural gas, NGL and crude oil purchasers or in governmental regulations or taxation will also affect actual future net cash flows. The timing of both the production and the expenses from the development and production of natural gas and crude oil properties will affect the timing of actual future net cash flows from proved reserves and their present value. In addition, the 10% discount factor, which is required by the SEC to be used in calculating discounted future net cash flows for reporting purposes, is not necessarily the most appropriate discount factor. The effective interest rate at various times and the risks associated with our business or the oil and natural gas industry in general will affect the appropriateness of the 10% discount factor in arriving at the reserves’ actual fair value.

Our production is concentrated in a small number of geographic areas.

     Approximately 75% of our 2008 production was from Texas and approximately 24% was from Alberta, Canada. Because of our concentration in these geographic areas, any regional events that increase costs, reduce availability of equipment or supplies, reduce demand or limit production, including weather and natural disasters, may impact us more than if our operations were more geographically diversified.

Our Canadian operations present unique risks and uncertainties, different from or in addition to those we face in our domestic operations.

     In addition to the various risks associated with our U.S. operations, risks associated with our operations in Canada, where we have substantial operations, include, among other things, risks related to increases in taxes and governmental royalties, changes in laws and policies governing operations of foreign-based companies, currency

restrictions and exchange rate fluctuations. Laws and policies of the United States affecting foreign trade and taxation may also adversely affect our Canadian operations.

We may have difficulty financing our planned growth.

     We have experienced capital expenditure and working capital needs, particularly as a result of our property acquisition and drilling activities. For 2009, we plan to operate our capital program within our operating cash flows. However, in the future, we may require additional financing above the level of cash generated by our operations to fund our growth. If revenue decreases as a result of lower petroleum prices or otherwise, our ability to expend the capital necessary to replace our reserves or to maintain production of current levels may be limited, resulting in a decrease in production over time. If our cash flow from operations is not sufficient to satisfy our capital expenditure requirements, we cannot be certain that additional financing will be available to us on acceptable terms or at all. In the event additional capital resources are unavailable, we may curtail our activities or be forced to sell some of our assets on an untimely or unfavorable basis.

We are vulnerable to operational hazards, transportation dependencies, regulatory risks and other uninsured risks associated with our activities.

     The oil and natural gas business involves operating hazards such as well blowouts, explosions, uncontrollable flows of crude oil, natural gas or well fluids, fires, formations with abnormal pressures, treatment plant “downtime”, pipeline ruptures or spills, pollution, releases of toxic gas and other environmental hazards and risks, any of which could cause us to experience substantial losses. Also, the availability of a ready market for our natural gas and crude oil production depends on the proximity of reserves to, and the capacity of, natural gas and crude oil gathering systems, treatment plants, pipelines and trucking or terminal facilities.

     U.S. and Canadian federal, state and provincial regulation of oil and natural gas production and transportation, tax and energy policies, changes in supply and demand and general economic conditions could adversely affect our ability to produce and market our natural gas, NGLs and crude oil. In addition, we may be liable for environmental damage caused by previous owners of properties purchased or leased by us.

     As a result of operating hazards, regulatory risks and other uninsured risks, we could incur substantial liabilities to third parties or governmental entities. We maintain insurance against some, but not all, of such risks and losses in accordance with customary industry practice. Generally, environmental risks are not fully insurable. The occurrence of an event that is not covered, or not fully covered, by insurance could have a material adverse effect on our business, financial condition and results of operations.

The failure to replace our reserves could adversely affect our production and cash flows.

     Our future success depends upon our ability to find, develop or acquire additional reserves that are economically recoverable. Our proved reserves will generally decline as reserves are produced, except to the extent that we conduct successful exploration or development activities or acquire properties containing proved reserves. In order to increase reserves and production, we must continue our development drilling and recompletion programs or undertake other replacement activities. Our current strategy is to maintain our focus on low-cost operations while increasing our reserve base and production through exploration and development of our existing properties. Our planned exploration or development projects or any acquisition activities that we may undertake might not result in meaningful additional reserves and we might not have continuing success drilling productive wells. Furthermore, while our revenue may increase if prevailing petroleum prices increase materially, our finding costs also could increase.

We have risk through our investment in BBEP.

     We own a 41% limited partner interest in BBEP, but have no management oversight over BBEP, its financial condition, its operating results or its financial reporting process and are subject to the risks associated with BBEP’s business and operations. Moreover, the management of BBEP has discretion over the amount, if any, that they distribute to unitholders, and on April 17, 2009 BBEP announced that it was suspending such distributions.

     The nature of our ownership interest in a publicly-traded entity subjects us to market risks associated with most ownership interests traded on a public exchange. Sales of substantial amounts of BBEP limited partner units, or a perception that such sales could occur, and various other factors, including BBEP suspending distributions on its units, could adversely affect the market price of BBEP limited partner units. Impairment to the carrying value of BBEP limited partnership units was recognized in both the forth quarter of 2008 and the first quarter of 2009, and could occur again in the future if the market price for BBEP units declines further. In the event of impairment of our BBEP units, we reduce the carrying value of our BBEP units and recognize expense in the amount of the impairment, which could be material and could adversely affect our financial condition and results of operations and our ability to borrow under and comply with the provisions of our debt agreements.

We have risk through our ownership of KGS.

     Through our ownership interest in KGS, we share in KGS’ results of operations and may be entitled to distributions from KGS. Accordingly, we have diminished control over assets owned by KGS and assets which KGS has a right to acquire. We are also subject to the risks associated with KGS’ business and operations, including, but not limited to:

• changes in general economic conditions;

• fluctuations in natural gas prices;

• failure or delays in us and third parties achieving expected production from natural gas projects;

• competitive conditions in the midstream industry;

• actions taken on non-performance by third parties, including suppliers, contractors, operators, processors, transporters and customers;

• changes in the availability and cost of capital;

• operating hazards, natural disasters, weather-related delays, casualty losses and other matters beyond our control;

• construction costs or capital expenditures exceeding estimated or budgeted amounts;

• the effects of existing and future laws and governmental regulations;

• the effects of future litigation; and

• other factors discussed in KGS’ Annual Report on Form 10-K and as are or may be detailed from time to time in KGS’ public announcements and other filings with the SEC.

We cannot control the operations of gas processing and transportation facilities we do not own or operate.

     We deliver our Canadian production to market primarily by either the TransCanada or ATCO systems. We have no influence over the operation of these facilities and must depend upon their owners to minimize any loss of processing and transportation capacity.

The loss of key personnel could adversely affect our ability to operate.

     Our operations are dependent on a relatively small group of key management personnel, including our executive officers. There is a risk that the services of all of these individuals may not be available to us in the future. Because competition for experienced personnel in our industry can be intense, we may be unable to find acceptable replacements with comparable skills and experience and their loss could have an adverse effect on us.

Competition in our industry is intense, and we are smaller and have a more limited operating history than many of our competitors.

     We compete with major and independent oil and natural gas companies for property acquisitions. We also compete for the equipment and labor required to develop and operate our properties. Many of our competitors have substantially greater financial and other resources than we do. In addition, larger competitors may be able to absorb the burden of any changes in federal, state, provincial and local laws and regulations more easily than we can, which would adversely affect our competitive position. These competitors may be able to pay more for exploratory prospects and productive natural gas and crude oil properties and may be able to define, evaluate, bid for and purchase a greater number of properties and prospects than we can. Our ability to explore for natural gas and crude

oil prospects and to acquire additional properties in the future will depend on our ability to conduct operations, to evaluate and select suitable properties and to complete transactions in this highly competitive environment. Furthermore, the oil and natural gas industry competes with other industries in supplying the energy and fuel needs of industrial, commercial, and other consumers.

Hedging our production may result in losses or limit our ability to benefit from price increases.

     To reduce our exposure to petroleum price fluctuations, we have entered into financial hedging arrangements which may limit the benefit we would receive from increases in petroleum prices. These hedging arrangements also expose us to risk of financial losses in some circumstances, including the following:

• our production could be materially less than expected; or

• the other parties to the hedging contracts could fail to perform their contractual obligations.

     The result of natural gas market prices exceeding collar ceilings requires us to make monthly cash payments. If we choose not to engage in hedging arrangements in the future, we could be more affected by changes in natural gas, NGL and crude oil prices than our competitors who engage in hedging arrangements.

Delays in obtaining oil field equipment and increases in drilling and other service costs could adversely affect our ability to pursue our drilling program and our results of operations.

     As natural gas, NGL and crude oil prices increase, demand and costs for drilling equipment, crews and associated supplies, equipment and services can increase significantly. We cannot be certain that in a higher petroleum price environment we would be able to obtain necessary drilling equipment and supplies in a timely manner or on satisfactory terms, and we could experience shortages of, or material increases in the cost of, drilling equipment, crews and associated supplies, equipment and services. Any such delays and price increases could adversely affect our ability to pursue our drilling program and our results of operations.

Our activities are regulated by complex laws and regulations, including environmental regulations that can adversely affect the cost, manner or feasibility of doing business.

     Natural gas, NGL and crude oil operations are subject to various U.S. and Canadian federal, state, provincial and local government laws and regulations that could change in response to economic or political conditions. Matters that are typically regulated include:

• discharge permits for drilling operations;

• water obtained for drilling purposes;

• drilling permits and bonds;

• reports concerning operations;

• spacing of wells;

• disposal wells;

• unitization and pooling of properties;

• environmental protection; and

• taxation.

     From time to time, regulatory agencies have imposed price controls and limitations on production by restricting the rate of flow of natural gas and crude oil wells below actual production capacity to conserve supplies of natural gas and crude oil. We also are subject to changing and extensive tax laws, the effects of which cannot be predicted.

     The development, production, handling, storage, transportation and disposal of natural gas and crude oil, by-products and other substances and materials produced or used in connection with our operations are also subject to laws and regulations primarily relating to protection of human health and the environment. The discharge of natural gas, crude oil or pollutants into the air, soil or water may give rise to significant liabilities on our part to the government and third parties and may result in the assessment of civil or criminal penalties or require us to incur substantial costs of remediation.

     Legal and tax requirements frequently are changed and subject to interpretation, and we are unable to predict the ultimate cost of compliance with these requirements or their effect on our operations. We cannot assure you that existing laws or regulations, as currently interpreted or reinterpreted in the future, or future laws or regulations, will not materially adversely affect our business, results of operations and financial condition.

The risks associated with our debt could adversely affect our business, financial condition and results of operations and the value of our securities.

     Subject to the limits contained in our various debt agreements, we may incur additional debt. Our ability to incur additional debt and to comply with the terms of our debt agreements is affected by a variety of factors, including natural gas, NGL and crude oil prices and their effects on our financial condition, results of operations and cash flows. Among other things, our ability to borrow under our Senior Secured Credit Facility is subject to the quantity and value of our proved reserves and other assets, including our investment in BBEP. If we incur additional debt or fail to increase the quantity and value of our proved reserves, the risks that we now face as a result of our indebtedness could intensify.

     We have demands on our cash resources in addition to interest expense, including operating expenses, principal payments under our debt and funding of our capital expenditures. Our level of debt, the value of our oil and gas properties and other assets, the demands on our cash resources, and the provisions of our debt agreements could have important effects on our business and on the value of our securities. For example, they could:

• make it more difficult for us to satisfy our obligations with respect to our debt;

• require us to dedicate a substantial portion of our cash flow from operations to payments on our debt, thereby reducing the amount of our cash flow available for working capital, capital expenditures, acquisitions and other general corporate purposes;

• require us to make principal payments if the quantity and value of our proved reserves are insufficient to support our level of borrowings;

• limit our flexibility in planning for, or reacting to, changes in the oil and natural gas industry;

• place us at a competitive disadvantage compared to our competitors who may have lower debt service obligations and greater financing flexibility than we do;

• limit our financial flexibility, including our ability to borrow additional funds;

• increase our interest expense on our variable rate borrowings if interest rates increase;

• limit our ability to make capital expenditures to develop our properties;

• increase our vulnerability to exchange risk associated with Canadian dollar denominated indebtedness;

• increase our vulnerability to general adverse economic and industry conditions; and

• result in a default or event of default under our debt agreements, which, if not cured or waived, could adversely affect our financial condition, results of operations and cash flows.

     Our ability to pay principal and interest on our debt, to otherwise comply with the provisions of our debt agreements and to refinance our debt may be affected by economic and capital markets conditions and other factors that may be beyond our control. If we are unable to service our debt and fund our other liquidity needs, we will be forced to adopt alternative strategies that may include:

• reducing or delaying capital expenditures;

• seeking additional debt financing or equity capital;

• selling assets;

• restructuring or refinancing debt; or

• reorganizing our capital structure.

     We cannot assure you that we would be able to implement any of these strategies on satisfactory terms, if at all, and our inability to do so could cause the holders of our securities to experience a partial or total loss of their investment in us.

Our debt agreements restrict our ability to engage in certain activities.

     Our debt agreements restrict our ability to, among other things:

• incur additional debt;

• pay dividends on or redeem or repurchase capital stock;

• make certain investments;

• incur or permit certain liens to exist;

• enter into certain types of transactions with affiliates;

• merge, consolidate or amalgamate with another company;

• transfer or otherwise dispose of assets, including capital stock of subsidiaries; and

• redeem subordinated debt.

     Our debt agreements, among other things, also require the maintenance of financial covenants that are more fully described in Note 2 to the condensed consolidated financial statements in Item 1 of this quarterly report. Our ability to comply with these covenants and other provisions of our debt agreements may be affected by events beyond our control, and we may be unable to comply with all aspects of our debt agreements in the future. In addition, our ability to borrow under our Senior Secured Credit Facility is dependent upon the quantity and value of our proved reserves and other assets, including our investment in BBEP.

     The provisions of our debt agreements may affect the manner in which we obtain future financing, pursue attractive business opportunities and plan for and react to changes in business conditions. In addition, failure to comply with the provisions of our debt agreements could result in an event of default which could enable the applicable creditors, subject to the terms and conditions of the applicable agreement, to declare the outstanding principal of that debt, together with accrued interest, to be immediately due and payable. Moreover, any of our debt agreements that contain a cross-default or cross-acceleration provision could also be subject to acceleration. If we were unable to repay the accelerated amounts, the creditors could proceed against the collateral granted to them to secure such debt. If the payment of our debt is accelerated, there can be no assurance that our assets would be sufficient to repay such debt in full, and the holders of our securities could experience a partial or total loss of their investment.

Parties with whom we do business may become unable or unwilling to timely perform their obligations to us.

     We enter into contracts and transactions with various third parties, including contractors, suppliers, customers, lenders and counterparties to hedging arrangements, under which such third parties incur performance or payment obligations to us. Any delay or failure on the part of one or more of such third parties to perform their obligations to us could, depending upon the nature and magnitude of such failure or failures, have a material adverse effect on our business, financial condition and results of operations.

A small number of existing stockholders exercise significant control over our company, which could limit your ability to influence the outcome of stockholder votes.

     Members of the Darden family, together with entities controlled by them, beneficially owned approximately 30% of our common stock as of March  31, 2009. As a result, they are generally able to significantly affect the outcome of stockholder votes, including votes concerning the election of directors, the adoption or amendment of provisions in our charter or bylaws and the approval of mergers and other significant corporate transactions.

A large number of our outstanding shares and shares to be issued upon conversion of our outstanding convertible debentures or exercise of our outstanding options may be sold into the market in the future, which could cause the market price of our common stock to drop significantly, even if our business is performing well.

     Our shares that are eligible for future sale may adversely affect the price of our common stock. There were more than 169 million shares of our common stock outstanding at March  31, 2009. Approximately 117 million of these shares are freely tradable without substantial restriction or the requirement of future registration under the Securities Act. In addition, when the conditions permitting conversion of our convertible debentures are satisfied, the holders could elect to convert such debentures. Based on the applicable conversion rate at March 31, 2009, the holders’ election to convert such debentures could result in an aggregate of 9,816,270 shares of our common stock

being issued. We also had options outstanding to purchase 3,675,128 shares of our common stock at March  31, 2009.

     Sales of substantial amounts of common stock, or a perception that such sales could occur, and the existence of conversion and option rights to acquire shares of common stock at prices that may be below the then current market price of the common stock, could adversely affect the market price of our common stock and could impair our ability to raise capital through the sale of our equity securities.

Our amended and restated certificate of incorporation, restated bylaws and stockholder rights plan contain provisions that could discourage an acquisition or change of control without our board of directors’ approval.

     Our amended and restated certificate of incorporation and restated bylaws contain provisions that could discourage an acquisition or change of control without our board of directors’ approval. In this regard:

• our board of directors is authorized to issue preferred stock without stockholder approval;

• our board of directors is classified; and

• advance notice is required for director nominations by stockholders and actions to be taken at annual meetings at the request of stockholders.

     In addition, we have adopted a stockholder rights plan which could also impede a merger, consolidation, takeover or other business combination involving us, even if that change of control might be beneficial to stockholders, thus increasing the likelihood that incumbent directors will retain their positions. In certain circumstances, the fact that corporate devices are in place that will inhibit or discourage takeover attempts could reduce the market value of our common stock.

     We have identified material weaknesses in our internal controls that, if not properly corrected, could result in material misstatements in our financial statements.

      We and our auditors have identified two material weaknesses in our system of internal control over financial reporting as of March 31, 2009. A material weakness is a deficiency, or combination of deficiencies in internal controls over financial reporting that results in a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

     The first material weakness related to the preparation of combined financial information within our condensed consolidating financial information. The condensed consolidating information previously reported contained errors that included “combining adjustments” for non-guarantor subsidiaries being reported within “consolidating eliminations” and in the amounts reported for equity earnings of wholly owned subsidiaries. These errors did not affect the amounts previously reported in our consolidated financial statements. To remedy this material weakness, we have revised our process to better structure the preparation and allow for further review of our consolidating financial information.

     The second material weakness related to the monitoring of our financial reporting requirements, particularly with respect to the form and content of our condensed consolidating financial information and the financial information about the Company and our restricted subsidiaries. To remedy this material weakness we have enhanced our process for documenting and satisfying the full extent of our financial reporting requirements.

     Although there can be no assurances, we believe these enhancements and improvements, when repeated in future periods, will remediate the material weaknesses described above. If we are not able to remedy the material weaknesses in a timely manner, we may be unable to provide our securityholders with the required financial information in a timely and reliable manner and we may incorrectly report financial information, either of which could subject us to litigation and regulatory enforcement actions.
