PART I. FINANCIAL INFORMATION

Item 1. Financial Statements (Unaudited)

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and
Stockholders of

Quicksilver Resources Inc.

Fort Worth, Texas

We have reviewed the
accompanying condensed consolidated balance sheet of Quicksilver Resources Inc. and subsidiaries (the Company) as of March 31, 2006, and the related condensed consolidated statements of income and comprehensive (loss) income and cash flows for
the three-month periods ended March 31, 2006 and 2005. These interim financial statements are the responsibility of the Companys management.

We
conducted our reviews in accordance with standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons
responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an
opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our reviews, we are not aware of any
material modifications that should be made to such condensed consolidated interim financial statements for them to be in conformity with accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of Quicksilver
Resources Inc. and subsidiaries as of December 31, 2005, and the related consolidated statements of income and comprehensive income, stockholders equity and cash flows for the year then ended (not presented herein); and in our report
dated March 1, 2006, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2005, is fairly
stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

As discussed in Note 2 to the condensed
consolidated financial statements, effective January 1, 2006, the Company adopted Statement of Financial Accounting Standards No. 123 (Revised 2004), Share-Based Payment.

QUICKSILVER RESOURCES INC.

NOTES TO CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS

UNAUDITED

1. ACCOUNTING POLICIES AND DISCLOSURES

The
accompanying condensed consolidated interim financial statements of Quicksilver Resources Inc. (Quicksilver or the Company) have not been audited by an independent registered public accounting firm. In the opinion of Company
management, the accompanying condensed consolidated interim financial statements contain all adjustments necessary to present fairly the financial position of the Company as of March 31, 2006 and its income, comprehensive income and cash flows
for the three-month periods ended March 31, 2006 and 2005. 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 of America 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. Management believes its estimates and assumptions are reasonable; however, such estimates and assumptions are subject to a number of risks and uncertainties, which may cause actual results to differ materially from the
Companys estimates.

Certain disclosures normally included in financial statements prepared in accordance with accounting principles
generally accepted in the United States of America have been condensed or omitted. Accordingly, these financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Companys Form
10-K for the year ended December 31, 2005.

Stock Split

On June 1, 2005, Quicksilver announced that its Board of Directors declared a three-for-two stock split of Quicksilvers outstanding common stock effected in the form of a stock dividend. The stock
dividend was payable on June 30, 2005, to holders of record at the close of business on June 15, 2005. The split did not affect treasury shares.

The share and earnings per share data included in these notes and the accompanying condensed consolidated statement of income for the prior period presented has been adjusted to retroactively reflect the stock split.

Net Income per Common Share

Basic net
income or loss per common share is computed by dividing the net income or loss attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted net income or loss per common share is
computed using the treasury stock method, which considers the impact to net income and common shares from the potential issuance of common shares underlying stock options, stock warrants and outstanding convertible securities. The following is a
reconciliation of the weighted average common shares used in the basic and diluted net income per common share calculations for the three-month periods ended March 31, 2006 and 2005. Outstanding options to purchase 2,401 shares and 1,637 shares
were excluded from the diluted net income per share calculation for the periods ended March 31, 2006 and 2005, respectively, as those options were out of the money and, therefore, considered to be antidilutive.

2. STOCK-BASED COMPENSATION

In December 2004, the Financial Accounting Standards Boards (FASB) issued SFAS No. 123 (revised 2004), Share-Based Payment (SFAS No. 123(R)).This statement
requires the cost resulting from all share-based payment transactions be recognized in the financial statements at their fair value on the grant date. SFAS No. 123(R) was adopted by the Company on January 1, 2006. The Company previously
accounted for stock awards under the recognition and measurement principles of APB No. 25, Accounting for Stock Issued to Employees, and related Interpretations. No stock-based employee compensation cost other than that for restricted
stock and stock unit grants was reflected in net income, as all options granted under the plan had an exercise price equal to the market value of the underlying common stock on the date of grant.

The Company adopted SFAS No. 123(R) using the modified prospective application method described in the statement. Under the modified prospective
application method, the Company applied the standard to new awards and to awards modified, repurchased, or cancelled after January 1, 2006. Additionally, compensation cost for the unvested portion of stock option awards outstanding as of
January 1, 2006 has been recognized as compensation expense as the requisite service is rendered after January 1, 2006. The compensation cost for unvested stock option awards granted before adoption of SFAS No. 123(R) shall be
attributed to periods beginning January 1, 2006 using the attribution method that was used under SFAS No. 123. At January 1, 2006, the Company had total compensation cost of $1.0 million, net of income taxes, related to unvested stock
options with a weighted average remaining vesting period of 1.5 years. The Company recorded expense of $0.2 million, net of income taxes, in the first quarter of 2006 for options awarded prior to the adoption of SFAS No. 123(R). At March 31,
2006, the Company had $0.8 million of expense, net of income taxes, remaining in unrecognized compensation cost for unvested stock options.

At January 1, 2006, the Company had total compensation cost of $3.2 million related to unvested restricted stock and stock unit awards. Additionally, the January 2006 grants of restricted stock and stock units had total compensation
cost of $11.5 million at the time of grant. During the first quarter of 2006, the Company recognized $0.8 million of expense, net of income tax, for vesting of restricted stock and stock units. Total unvested compensation cost was $13.2 million at
March 31, 2006 with a weighted average remaining vesting period of 1.8 years.

Prior to the adoption of SFAS 123(R), the Company
presented any tax benefits of deductions resulting from the exercise of stock options within operating cash flows in the condensed consolidated statements of cash flow. SFAS 123(R) requires tax benefits resulting from tax deductions in excess of the
compensation cost recognized for those options (excess tax benefits) to be classified and reported as both an operating cash outflow and a financing cash inflow upon adoption of SFAS 123(R). As a result of the Companys net
operating losses, the excess tax benefits that would otherwise be available to reduce income taxes payable have the effect of increasing the Companys net operating loss carry forwards. Accordingly, because the Company is not currently able to
realize these excess tax benefits, such benefits have not been recognized in the condensed statement of cash flow for the quarterly period ended March 31, 2006.

Employee Stock Plans

On October 4, 1999, the Board of Directors adopted the Companys 1999 Stock Option and Retention Stock Plan (the 1999 Plan), which was approved at the annual stockholders meeting held in
June 2000. Upon approval of the 1999 Plan, 3.9 million shares of common stock were reserved for issuance pursuant to grants of incentive stock options, non-qualified stock options, stock appreciation rights and retention stock awards. Pursuant
to an amendment approved at the annual shareholders meeting held in May 2004, an additional 3.6 million shares were reserved for issuance pursuant to the 1999 Plan.

In February 2004, the Board of Directors adopted the Companys 2004 Non-Employee Director Equity Plan (the 2004 Plan), which was
approved at the annual stockholders meeting held in May 2004. There were 750,000 shares reserved under the 2004 Plan, which provides for the grant of non-qualified options and restricted stock awards to Quicksilvers non-employee
directors.

Under terms of the 1999 Plan and 2004 Plan, retention stock awards and options may be granted to officers, employees and
non-employee directors at an exercise price that is not less than 100% of the fair market value on the date of grant. Incentive stock options and non-qualified options may not be exercised more than ten years from date of grant.

Stock Options

On January 3, 2006, a
non-employee director of the Company received options to purchase a total of 2,401 shares of stock at a strike price of $44.39. These options will become fully vested one year from the date of grant provided the non-employee director remains a
member of the Board of Directors of the Company.

The following table summarizes the Companys stock option activity during the first
quarter of 2006.

Restricted Stock
Grants

During January 2006, the Company awarded 254,685 shares of restricted stock and stock units at a weighted average market price
of $43.77. Of the stock awarded, 90,000 shares were awarded to executive officers as a retention award that will cliff vest in January 2009. The remaining restricted stock and stock unit awards will vest ratably over a three-year period. On
January 3, 2006, the non-employee directors of the Company received a grant of 6,760 restricted shares at a market value of $44.39 per share. These restricted shares will become fully vested one year from the date of grant provided the
non-employee director remains a member of the Board of Directors of the Company.

The fair values of all natural gas and crude oil financial instruments and firm sale and purchase
commitments as of March 31, 2006 and December 31, 2005 were estimated based on market prices of natural gas and crude oil for the periods covered by the hedge derivatives. The net differential between the contractual prices in each hedge
derivative and commitment and market prices for future periods, as adjusted for estimated basis, has been applied to the volumes stipulated in each contract to arrive at an

estimated future value. This estimated future value was discounted on each contract at rates commensurate with federal treasury instruments with similar
contractual lives. As a result, the estimated fair value of the Companys hedge derivatives and sales commitments does not necessarily represent the value a third party would pay or be paid to assume the Companys contract positions.

At March 31, 2006, derivative assets of $2.8 million and derivative liabilities of $6.9 million have been classified as current based
on the maturity of the derivative instruments. The Company estimates $2.6 million of after-tax losses will be reclassified from other comprehensive income over the next twelve months.

On March 16, 2006, the Company issued $350 million in principal amount of Senior Subordinated
Notes due 2016 (Senior Subordinated Notes). The Senior Subordinated Notes are unsecured, senior subordinated obligations of the Company and bear interest at an annual rate of 7.125% payable semiannually on April 1 and October 1
of each year. The terms and conditions of the Senior Subordinated Notes require the Company to comply with certain covenants, which primarily limit certain activities, including, among other things, levels of indebtedness, restricted payments,
payments of dividends, capital stock repurchases, investments, liens, distributions from restricted subsidiaries, affiliate transactions and mergers and consolidations. At March 31, 2006, the Company was in compliance with such covenants.

In March 2006, the Company used $70 million of the proceeds from the Senior Subordinated Notes to retire the second lien mortgage notes.
As a result of the repayment, the Company recognized additional interest expense of $1.0 million consisting of a prepayment premium of $0.8 million and a charge of $0.3 million for associated unamortized deferred financing costs, partially offset by
recognition of an associated deferred hedging gain of $0.1 million.

As of March 31, 2006, the Companys borrowing base under its
senior secured credit facility was $600 million, of which approximately $327.4 million was available for borrowing. The loan agreements for the senior credit facility prohibit the declaration or payment of dividends by the Company and contain
certain financial covenants, which, among other things, require the maintenance of a minimum current ratio and a minimum earnings (before interest, taxes, depreciation, depletion, amortization, non-cash income and expense and exploration costs) to
interest ratio. The Company was in compliance with all such covenants at March 31, 2006.

5. ASSET RETIREMENT OBLIGATIONS

The Company records the fair value of the liability for asset retirement obligations in the period in which it is incurred. Upon initial recognition of
the asset retirement liability, an asset retirement cost is capitalized by increasing the carrying amount of the long-lived asset by the same amount as the liability. In periods subsequent to initial measurement, the asset retirement cost is
allocated to expense using a systematic method over the assets useful life. Changes in the liability for the asset retirement obligation are recognized for (a) the passage of time and (b) revisions to either the timing or the amount
of the original estimate of undiscounted cash flows.

During the three-month periods ended March 31, 2006 and 2005, accretion expense
was recognized and included in depletion, depreciation and accretion expense reported in the consolidated statement of income for the period. At March 31, 2006 and December 31, 2005, retirement obligations classified as current were $0.1
million. The following table provides a reconciliation of the changes in the estimated asset retirement obligation for the three-month periods ended March 31, 2006 and 2005.

6. COMMITMENTS AND CONTINGENCIES

In August 2001, a group of royalty owners, Athel E. Williams et al., brought suit against the Company and three of its subsidiaries in the Circuit Court
of Otsego County, Michigan. The suit alleges that Terra Energy Ltd, one of Quicksilvers subsidiaries, underpaid royalties or overriding royalties to the 13 named plaintiffs and to a class of plaintiffs who have yet to be determined. The
pleadings of the plaintiffs seek damages in an unspecified amount and injunctive relief against future underpayments. On January 21, 2005, the Circuit Court issued an order certifying certain claims to proceed on behalf of a class. The
certification is currently under appeal with the Michigan Court of Appeals.

Based on information currently available to the Company, the
Companys management believes that the final resolution of this matter will not have a material effect on its financial position, results of operations, or cash flows.

As of March 31, 2006, the Company had entered into contracts for the use of eight drilling rigs in its drilling and exploration programs for periods
ranging from one to three years at estimated day rates ranging from $15,500 to $21,500 per day. Each of the contracts requires payment of the specified day rate for the entire lease term of each contract regardless of the Companys utilization
of the drilling rigs. Under these contracts, the Company estimates $137.8 million will be paid as follows: $16.7 million in 2006; $51.3 million in 2007; $47.7 million in 2008; and, $22.1 million in 2009.

The Company is subject to various possible contingencies, which arise primarily from interpretation of federal and state laws and regulations affecting
the natural gas and crude oil industry. Such contingencies include differing interpretations as to the prices at which natural gas and crude oil sales may be made, the prices at which royalty owners may be paid for production from their leases,
environmental issues and other matters. Although management believes it has complied with the various laws and regulations, administrative rulings and interpretations thereof, adjustments could be required as new interpretations and regulations are
issued. In addition, production rates, marketing and environmental matters are subject to regulation by various federal and state agencies.

8. RELATED PARTY TRANSACTIONS

As of March 31, 2006, members of the Darden family, Mercury Exploration Company (Mercury) and Quicksilver Energy L.P., entities that are owned by members of the Darden family, beneficially owned
approximately 34% of the Companys outstanding common stock. Thomas Darden, Glenn Darden and Anne Darden Self are officers and directors of the Company.

Quicksilver and its associated entities paid $0.3 million and $0.2 million for rent in the first three months of 2006 and 2005, respectively, for rent on buildings owned by Pennsylvania Avenue LP (PALP), a
Mercury affiliate. Rental rates were determined based on comparable rates charged by third parties. In February 2006, the Company entered into an amendment to its lease with PALP to increase the amount of office space covered thereby. In conjunction
with this lease amendment, in February 2006, the Company also entered into a sublease for a portion of the property it leases from PALP to Mercury. The rental rate under the sublease was determined using comparable rates charged by third parties.
During 2006, the Company has paid Regal Aviation LLC, an unrelated airplane management company, $0.1 million for use of an airplane owned by Sevens Aviation, LLC, a company owned indirectly by members of the Darden family. Usage rates are determined
based on comparable rates charged by third parties.

Natural gas sales of $86.9 million for the first quarter of 2006 were 82% higher than the $47.9
million for the first quarter of 2005. A $2.63 per Mcf increase in average realized sales prices increased natural gas revenue $29.0 million. Natural gas revenue also increased $10.0 million because of a 13% increase in sales volumes as compared to
the first quarter of 2005. Production from our coal bed methane (CBM) projects and conventional properties in Canada increased for the first quarter of 2006 by approximately 1.1 MMcf from the first quarter of 2005 as a result of
new wells placed into production since March 31, 2005. Natural production declines partially offset the Canadian production increases. New productive wells in the Fort Worth Basin in north Texas increased sales volumes by approximately 1.3 MMcf
for the first quarter of 2006 compared to the first quarter of 2005. U.S. production increases were partially offset by natural production declines.

Oil and condensate sales were $8.4 million for the three months ended March 31, 2006 compared to $5.9 million for the first quarter of 2005. Higher production, primarily from new productive wells in the Fort
Worth Basin, increased revenue by $0.9 million compared to the prior year quarter. The average realized oil and condensate sales price for the first quarter of 2006 was $58.64 per Bbl compared to $46.05 per Bbl in the first quarter of 2005. Higher
realized sales prices increased revenue by $1.6 million.

Our first quarter 2006 NGL sales increased $2.3 million to $3.4 million when
compared to the first quarter of 2005. NGL production increased by almost 52,500 Bbl compared to the first quarter of 2005. NGL production in the Fort Worth Basin increased approximately 42,100 Bbl as a result of new productive wells and gas
processing facilities in the Fort Worth Basin.

Oil and gas operations expense was $21.4 million for the 2006 first quarter. The $4.4 million
increase over the prior year quarter included a $1.7 million increase in Canadian production costs. Canadian operating costs were $5.2 million for the first quarter of 2006. Compared to the first quarter of 2005, production overhead increased $1.3
million. Compensation expense increased over $1.0 million, including $0.2 million for vesting of restricted stock and stock option awards, primarily as a result of an increase of 19 employees. Operation of gas facilities constructed in 2005
contributed to the remainder of the Canadian operating cost increase.

Oil and gas operations expense for U.S. operations increased $2.7
million from the prior years quarter to $16.2 million for the first quarter of 2006. The growth of our operations in the Fort Worth Basin increased operating expense approximately $2.8 million. The increases were primarily for transportation,
processing, salt water disposal and equipment rentals. U.S. production overhead for the first three months of 2006 increased approximately $0.9 million as compared to the first quarter of 2005. Increased operating activity and the addition of
employees in Texas contributed $0.5 million of the increase while vesting of restricted stock and stock option awards contributed approximately $0.2 million of the increase in U.S. production overhead. Increases in production overhead were partially
offset by a $0.3 million decrease in expense for compressor overhauls and repairs in Michigan as well as smaller decreases in several other expense categories for the first quarter of 2006 as compared to the 2005 period.

Production and Ad Valorem Taxes

Production and ad
valorem tax expense for the first three months of 2006 was $4.2 million compared to $2.7 million for the first quarter of 2005. Production taxes increased $1.0 million for the first quarter of 2006 as a result of higher sales volumes and sales
prices during the period. The increase in ad valorem taxes for the 2006 period was primarily the result of additional assets constructed and acquired in conjunction with our drilling program in the Fort Worth Basin.

Depletion for the first quarter of 2006 was $14.8 million and $4.1 million higher than depletion
for the 2005 quarter primarily as a result of a 20% increase in the depletion rate and a 15% increase in sales volumes. Our depletion rate increased over the first quarter of 2005 as a result of our significant actual and estimated future capital
expenditures and proved reserves added for our

Canadian CBM and Forth Worth Basin properties. The $1.2 million increase in depreciation for the first quarter of 2006 is associated with new gas processing
facilities in Canada and gas processing and transportation assets located in the Fort Worth Basin.

General and Administrative Expense

General and administrative expense for the three months ended March 31, 2006 was $6.3 million. The most significant increase in general and
administrative expense for the first quarter of 2006 was the $1.9 million increase in employee compensation and benefits, including approximately $0.8 million of expense for vesting of restricted stock and stock option awards. Additionally,
approximately 20 additional employees were employed in the corporate office during the first quarter of 2006 compared to the first quarter of 2005. Office rentals, insurance and other related expenses increased approximately $0.5 million as a result
of additional office space and employees. Legal fees increased approximately $0.3 million for the first quarter of 2006 primarily as a result of a review of our debt indentures for our senior credit facility and second lien mortgage notes, and
general corporate legal work handled by outside attorneys. Several smaller increases made up the remainder of the $0.4 million increase in general and administrative expense for the first quarter of 2006 as compared to the 2005 period.

Interest Expense

Interest expense for the first
quarter of 2006 was $9.2 million, net of capitalized interest of $0.4 million, an increase of $4.5 million compared to the first quarter of 2005. Interest expense for the first quarter of 2006 included a charge of $1.0 million as a result of the
prepayment of $70.0 million in principal amount of our second lien mortgage notes payable with a portion of the proceeds from the issuance of $350 million in principal amount of our senior subordinated notes. The $1.0 million charge consisted of a
prepayment premium of $0.8 million and the write-off of $0.3 million of remaining deferred financing costs, partially offset by recognition of the remainder of an associated deferred hedging gain of $0.1 million. Recurring interest expense increased
primarily as a result of higher debt levels during the first quarter of 2006. Higher interest rates during the first quarter of 2006 also contributed to increased interest expense.

Income Tax Expense

Our provision for income taxes increased $8.9 million from the prior year period
as a result of higher pretax income for the first quarter of 2006. Our U.S. income tax provision of $8.6 million was established using the statutory U.S. federal rate of 35%. The Canadian tax provision of approximately $5.0 million was accrued at a
Canadian combined federal and provincial statutory rate of 33.6% and included a current tax provision of $0.1 million.

LIQUIDITY, CAPITAL RESOURCES AND
FINANCIAL POSITION

Net cash from operations was $63.3 million for the three months ended March 31, 2006, an increase of $41.2
million compared to the same period in 2005. The increase was due primarily to additional net income for the first quarter of 2006 as compared to the 2005 period. Net income of $27.5 was $16.8 million higher than net income for the first quarter of
2005 primarily as a result of a 15% increase in sales volumes and a 56% increase in realized sales prices. Non-cash expenses including depletion, depreciation and amortization, deferred taxes, stock-based compensation and deferred financing costs
increased for 2006 by $15.8 million.

Our principal sources of cash include sales of natural gas, crude oil and NGLs. During the three
months ended March 31, 2006, sales under our long-term contracts with price floors covered 22% of our natural gas production. Additionally, price collars covered 58% of our 2006 first quarter production. As of May 1, 2006, we have price
collars hedging our natural gas and crude oil production of approximately 73,400 Mcfd and 1,500 Bbld, respectively, for the remainder of 2006. The natural gas collars have weighted average price floors and caps of $7.27 per Mcf and $10.11 per Mcf,
respectively, and the crude oil collars have average price floors and caps of $49.67 per Bbld and $83.22 per Bbld, respectively. We have hedged approximately 42,200 Mcfd of our estimated 2007 natural gas sales using price collars with average price
floors and caps of $7.78 per Mcf and $12.34 per Mcf, respectively.

In the first quarter of 2006, we paid $140.0 million for property and
equipment, an increase of $79.6 million when compared to the first quarter of 2005. Property and equipment costs incurred (payments for property and equipment plus noncash changes in working capital associated with property and equipment) for the
2006 period totaled $133.6 million, which consisted of $102.2 million expended for exploration and development activities, $22.3 million expended for construction of the Cowtown gas processing facility in Hood County, Texas and lateral extensions of
the Cowtown pipeline and $7.9 million expended for Canadian gas processing facilities. Of the $73.1 million incurred for U.S. exploration and development, $63.6 million was spent in Texas, including $6.7 million for non-producing leasehold costs.
Canadian leasehold costs were $1.7 million of the $29.0 million spent on Canadian exploration and development.

Net cash provided by financing activities for the three months ended March 31, 2006 was
$187.2 million. On March 16, 2006, we issued $350 million in principal amount of Senior Subordinated Notes due in 2016. The Senior Subordinated Notes are unsecured, senior subordinated obligations and bear interest at an annual rate of 7.125%
payable semiannually on April 1 and October 1 of each year. The terms and conditions of the Senior Subordinated Notes require us to comply with certain covenants, which primarily limit certain activities, including, among other things,
levels of indebtedness, restricted payments, payments of dividends, capital stock repurchases, investments, liens, distributions from restricted subsidiaries, affiliate transactions, transfers or sales of assets and mergers and consolidations. At
March 31, 2006, we were in compliance with such covenants.

In March 2006, we used $70 million of the proceeds of the Senior
Subordinated Notes to retire our second lien mortgage notes. As a result of the repayment, we recognized additional interest expense of $1.0 million consisting of a prepayment premium of $0.8 million and a charge of $0.3 million for associated
unamortized deferred financing costs, partially offset by recognition of an associated deferred hedging gain of $0.1 million. We also used approximately $128 million of the proceeds to repay a portion of the borrowings outstanding under the U.S.
portion of our senior secured credit facility.

As of March 31, 2006, our borrowing base under our senior secured credit facility was
$600 million, of which approximately $327.4 million was available for borrowing. The loan agreements for the senior credit facility prohibit the declaration or payment of dividends by us and contain certain financial covenants, which, among other
things, require the maintenance of a minimum current ratio and a minimum earnings (before interest, taxes, depreciation, depletion, amortization, non-cash income and expense and exploration costs) to interest ratio. We were in compliance with all
such covenants at March 31, 2006.

As of March 31, 2006 and December 31, 2005, our total capitalization was as follows:

Contractual Obligations and Commercial Commitments

Information regarding our contractual obligations as of March 31, 2006 is set forth below. This information should be read in conjunction with the
information provided in the contractual obligations and commercial commitments table included in our Annual Report on Form 10-K for the period ended December 31, 2005.

Our outstanding long-term debt as of March 31, 2006, was $769.8 million, which includes $350 million in principal amount of Senior Subordinated
Notes due in 2016. We pay interest semi-annually at a rate of 7.125% per annum. In March 2006, we used $70 million of the proceeds from issuance of the Senior Subordinated Notes to retire our second lien mortgage notes and approximately $128
million of the proceeds to repay some of the borrowings outstanding under the U.S. portion of our senior secured credit facility. In April 2006, we used an additional $64.5 million of the proceeds to repay the remaining borrowings outstanding under
the U.S. portion of our senior secured credit facility outstanding.

At March 31, 2006, we were contractually obligated to purchase goods and services in connection with
construction of two gas processing plants in Texas. For the first gas processing plant, we have $2.5 million remaining in purchase obligations including $1.5 million recorded as a liability at March 31, 2006. Our total remaining purchase
obligations for construction and completion of the second gas processing plant at March 31, 2006 were $17.4 million including liabilities of $4.1 million recorded for goods received and services performed.

We lease drilling rigs from third parties for use in our development and exploration programs. At March 31, 2006 we had entered into the following
contracts for use of eight drilling rigs:



|                        |  |                 |  |

|1                       |  | $18,500 per day |  | Two years beginning January 2007    

Each of the contracts requires payment of the specified day rate for the entire lease term
regardless of our utilization of the drilling rigs. We estimate $137.8 million will be paid under the contracts as follows: $16.7 million in 2006; $51.3 million in 2007; $47.7 million in 2008; and, $22.1 million in 2009.

Stock-Based Compensation

In December 2004, the
Financial Accounting Standards Boards (FASB) issued SFAS No. 123 (revised 2004), Share-Based Payment (SFAS No. 123(R)).This statement requires the cost resulting from all share-based payment
transactions be recognized in the financial statements at their fair value on the grant date. We adopted SFAS No. 123(R) on January 1, 2006. We previously accounted for stock awards under the recognition and measurement principles of APB
No. 25, Accounting for Stock Issued to Employees, and related Interpretations. No stock-based employee compensation cost other than that for restricted stock and stock unit grants was reflected in net income, as all options granted under
the plan had an exercise price equal to the market value of the underlying common stock on the date of grant.

We adopted SFAS
No. 123(R) using the modified prospective application method described in the statement. Under the modified prospective application method, we have applied the standard to new awards and to awards modified, repurchased, or cancelled after
January 1, 2006. Additionally, compensation cost for the unvested portion of stock option awards outstanding as of January 1, 2006 has been recognized as compensation expense as the requisite service is rendered after January 1, 2006.
The compensation cost for unvested stock option awards granted before adoption of SFAS No. 123(R) shall be attributed to periods beginning January 1, 2006 using the attribution method that was used under SFAS No. 123. At
January 1, 2006, we had total compensation cost of $1.1 million related to unvested stock options with a weighted average remaining vesting period of 1.5 years. We recorded $0.2 million of compensation expense in the first quarter of 2006 for
stock option grants awarded prior to adoption of SFAS No. 123(R) and will recognize an additional $0.4 million of expense, net of income taxes, over the remainder of 2006. All compensation costs for restricted stock and stock unit grants was
recorded as previously required under the recognition and measurement principles of APB No. 25, Accounting for Stock Issued to Employees, and related Interpretations. We recorded compensation expense of $1.2 million and $0.1 million for
all stock awards during the three-month periods ending March 31, 2006 and 2005, respectively.

ITEM 3. Quantitative and Qualitative Disclosures About Market Risk

We have established policies and
procedures for managing risk within our organization, including internal controls. The level of risk assumed by us is based on our objectives and capacity to manage risk.

Our primary risk exposure is related to natural gas and crude oil commodity prices. We have mitigated the risk of adverse price movements through the use of swaps and collars; however, we have also limited future
gains from favorable movements.

Commodity Price Risk

We enter into financial contracts to hedge our exposure to commodity price risk associated with anticipated future natural gas production. These contracts have included no-cost collars and fixed price swaps. We sell
approximately 10.0 MMcfd and 25.0 MMcfd of natural gas for floor prices of $2.47 per Mcf and $2.49 per Mcf, respectively, under long-term contracts that extend through March 2009. Approximately 3.8 MMcfd of the natural gas sold under these contracts
during the first three months of 2006 were third-party volumes controlled by us.

As of May 1, 2006, we have hedged approximately 73.4
MMcfd of our natural gas production for the remaining nine months of 2006 using no-cost collars with a weighted average floor price of $7.27 per Mcf and a weighted average cap price of $10.11 per Mcf. We also have 1,500 Bbld of oil and condensate
production hedged with price collars for the remainder of 2006.

Price collars have also been put in place to hedge 2007 natural gas
production of approximately 42.2 MMcfd and first quarter 2008 natural gas production of approximately 20.0 MMcfd. Crude oil production of 2,000 Bbld has been hedged for the first half of 2007 using no-cost collars with a floor price of $50.00 per
Bbl and a cap price of $85.85 per Bbl.

The following table summarizes our open financial hedge positions as of March 31, 2006 related
to natural gas and crude oil production.

Commodity price fluctuations affect our remaining natural gas and crude oil volumes as well as our
NGL volumes. We also sell a portion of our natural gas under long-term natural gas sales contracts with market pricing. Up to 4.5 MMcfd of natural gas is committed at market price through May 2006. Additional natural gas volumes of 16.5 MMcfd are
committed at market price through September 2008. Approximately 8.9 MMcfd of our natural gas production was sold under these contracts. The remaining contractual volumes were third-party volumes controlled by us.

We also enter into financial contracts to hedge our exposure to commodity price risk associated with
future contractual natural gas sales and purchases. These contracts consist of fixed price sales to third parties. As a result of these firm sale commitments, the associated financial price swaps have qualified as fair value hedges. The following
table summarizes our open financial derivative positions and hedged firm commitments as of March 31, 2006 related to natural gas marketing.

Utilization of our hedging program may result in natural gas and crude oil realized prices varying
from market prices that we receive from the sale of natural gas and crude oil. Our revenue from natural gas and crude oil production was $2.3 million and $9.6 million lower as a result of the hedging programs for the first three months of 2006 and
2005, respectively. Marketing revenue was $0.2 million and $0.3 million lower as a result of hedging activities in the first quarter of 2006 and 2005, respectively.

Interest Rate Risk

Our interest rate swap covering $75.0 million notional variable-rate debt ended
on March 31, 2005. The interest rate swap converted a floating three-month LIBOR base to a 3.74% fixed-rate.

A gain of $0.3 million
for the termination of an interest rate swap hedging $40.0 million of fixed-rate second lien mortgage notes in January 2004 was deferred and was being recognized over the period remaining to original maturity of our second lien mortgage notes. We
repaid and retired the second lien mortgage notes in March 2006. The remaining deferred gain of $0.1 million was recognized upon retirement of these notes.

As a result of these swaps, interest expense was $0.1 million and $0.2 million lower, respectively, for the three months ended March 31, 2006 and 2005.

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 the end of the first quarter of 2006, our disclosure controls and procedures were 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 on a timely basis.

Changes in Internal Control Over Financial Reporting

In January 2006, Quicksilver Resources Canada Inc., our Canadian subsidiary, implemented Qbyte FM software for its general ledger system. This implementation resulted in certain changes to processes and internal controls impacting financial
reporting. While there are inherent risks involved with the implementation of any new system, management believes that it is adequately monitoring and managing the transition and that this change will enhance our internal control over financial
reporting. There has been no other change in our internal control over financial reporting during the quarter ended March 31, 2006 that has materially affected, or is reasonably likely to materially affect, our internal control over financial
reporting.
