NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

1. FINANCIAL STATEMENT PRESENTATION

During interim periods, Petrohawk Energy Corporation (Petrohawk or the Company) follows the same accounting policies used in its Report on Form 10-K, as amended and filed with the Securities and Exchange Commission (SEC). People using financial information produced for interim periods are encouraged to refer to the footnotes in the Form 10-K when reviewing interim financial results.

These unaudited consolidated financial statements reflect, in the opinion of the Company’s management, all adjustments, consisting only of normal and recurring adjustments, necessary to present fairly the financial position as of, and results of operations for, the periods presented. Interim period results are not necessarily indicative of results of operations or cash flows for the full year.

Recently Issued Accounting Pronouncements

In May 2005, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 154, Accounting Changes and Error Corrections-A replacement of APB Opinion No. 20 (APB 20) and FASB Statement No. 3 (SFAS 154). In order to enhance financial reporting consistency between periods, SFAS 154 modifies the requirements for the accounting and reporting of the direct effects of changes in accounting principles. Under APB 20, the cumulative effect of voluntary changes in accounting principle was recognized in net income in the period of the change. Unlike the treatment previously prescribed by APB 20, retrospective application is now required, unless it is not practical to determine the specific effects in each period or the cumulative effect. If the period specific effects cannot be determined, it is required that the new accounting principle must be retrospectively applied in the earliest period possible to the balance sheet accounts and a corresponding adjustment be made to the opening balance of retained earnings or another equity account. If the cumulative effect cannot be determined, it is necessary to apply the new accounting principles prospectively at the earliest practical date. If it is not feasible to retrospectively apply the change in principle, the reason that this is not possible and the method used to report the change is required to be disclosed. The statement also provides that changes in accounting for depreciation, depletion or amortization should be treated as changes in an accounting estimate inseparable from a change in accounting principle and that disclosure of the preferability of the change is required. SFAS 154 is effective for accounting changes made in fiscal years beginning after December 15, 2005. The Company adopted this FASB on January 1, 2006. The adoption of this pronouncement did not materially impact the Company’s operating results, financial position or cash flows.

In December 2004, the FASB issued SFAS No. 123(R), Share-Based Payment (SFAS 123(R)). SFAS 123(R) revises SFAS No. 123, Accounting for Stock-Based Compensation (SFAS 123), and focuses on accounting for share-based payments for services provided by employee to employer. The statement requires companies to expense the fair value of employee stock options and other equity-based compensation at the grant date. The statement does not require a certain type of valuation model, and either a binomial or Black-Scholes model may be used. During the first quarter of 2005, the SEC approved a new rule for public companies to delay the adoption of this standard. In April 2005, the SEC took further action to amend Regulation S-X to state that the provisions of SFAS No. 123(R) will be effective beginning with the first annual or interim reporting period of the registrant’s first fiscal year beginning on or after June 15, 2005 for all non-small business issuers. As a result, the Company did not adopt this SFAS until January 1, 2006. The Company used the modified prospective application method as detailed in SFAS No. 123(R). The adoption of this pronouncement did not materially impact the Company’s operating results, financial position or cash flows. See Stock-Based Compensation below for further information.

Stock-Based Compensation

Prior to 2006, the Company followed SFAS No. 123 and related interpretations in accounting for its employee and director stock options and applied the fair value based method of accounting to such options. Under SFAS 123, the fair value of each option granted is estimated on the date of grant using the Black-Scholes option-pricing model. All activity in 2005 was accounted for under SFAS 123 and was included in stock-based compensation in the Company’s operating events.

In December 2004, the FASB issued SFAS 123(R). SFAS 123(R) is a revision of SFAS No. 123, Accounting for Stock Based Compensation, and supersedes APB 25, Accounting for Stock Issued to Employees (APB 25). Among other items, SFAS 123(R) eliminates the use of APB 25 and the intrinsic value method of accounting and requires companies to recognize the cost of employee services received in exchange for awards of equity instruments based on the grant date fair value of those awards in their financial statements. As allowed by SFAS 123R, the Company continued utilizing the Black-Scholes option pricing model to measure the fair value of stock options granted upon adoption of SFAS 123(R).

The assumptions used in the fair value method calculation for the three months ended March 31, 2006 and 2005 are disclosed in the following table:


	Three Months Ended March 31,
	2006		2005
Weighted average value per option granted during the period ⁽¹⁾	$	4.07	$	1.99
Assumptions ⁽²⁾:
Stock price volatility		35.0%		27.2%
Risk free rate of return		4.4%		3.4%
Expected term		3 years		3 years

⁽¹⁾

Calculated using the Black-Scholes fair value based method.

⁽²⁾

The Company does not pay dividends on its common stock.

The following table sets forth the option transactions for the three-month period ended March 31, 2006 (dollars in thousands).


	Number of Options		Weighted Average Exercise Price Per Share		Aggregate Intrinsic Value ⁽¹⁾		Weighted Average Remaining Contractual Life (Years)
Outstanding at December 31, 2005	5,698,547		$	6.16			5.6

Granted	802,000			14.03
Exercised	(75,245	)		7.91
Forfeited	(21,729	)		9.55

Outstanding at March 31, 2006	6,403,573		$	7.07	$	42,449	5.9

Exercisable at March 31, 2006	4,648,901		$	5.45	$	38,353	4.6

⁽¹⁾

The intrinsic value of a stock option is the amount by which the current market value of the underlying stock exceeds the exercise price of the option. The aggregate intrinsic value of stock options exercised during the three month period ended March 31, 2006 was approximately $0.5 million.

There were no options which expired in the three month period ended March 31, 2006. The weighted average grant date fair value of options granted during the three month period ended March 31, 2006 was $3.3 million. At March 31, 2006, the unrecognized compensation expense related to non-vested stock options totaled $3.9 million and will be recognized on a straight line basis over the vesting period.

The following table sets forth the restricted stock transactions for the three-month period ended March 31, 2006 (dollars in thousands).


	Number of Shares		Weighted Average Grant Date Fair Value Per Share		Aggregate Intrinsic Value *⁽¹⁾*
Unvested outstanding shares at December 31, 2005	73,334		$	10.87

Granted	223,500			15.62
Vested	(21,667	)		10.76
Forfeited	(1,667	)		8.51


Unvested outstanding shares at March 31, 2006	273,500		$	14.77	$	3,747

⁽¹⁾

The intrinsic value of restricted stock was calculated as the closing market price on March 31, 2006 of the underlying stock multiplied by the number of restricted shares. The intrinsic value of the shares vested for the three months ended March 31, 2006 was $0.3 million.

The weighted average grant date fair value of the shares granted during the three month period ended March 31, 2006 is $3.4 million. At March 31, 2006, the unrecognized compensation expense related to non-vested restricted stock totaled $3.5 million and will be recognized on a straight line basis over the vesting period.

2. ACQUISITIONS AND DIVESTITURES

Gulf of Mexico Divestiture

On March 21, 2006, the Company completed the sale of substantially all of its Gulf of Mexico properties for $52.5 million ($43.2 million after certain closing adjustments). The transaction had an effective date of January 1, 2006.

The North Louisiana Acquisitions

On January 27, 2006, the Company completed the acquisition of all of the issued and outstanding common stock of Winwell Resources, Inc. (Winwell) pursuant to a Stock Purchase Agreement with Winwell and all of its shareholders made and entered into as of December 14, 2005 (the Stock Purchase Transaction). Winwell is engaged in oil and gas exploration and production activities. The aggregate consideration paid in the Stock Purchase Transaction was approximately $208 million in cash after certain closing adjustments.

The Stock Purchase Transaction was accounted for using the purchase method of accounting under the accounting standards established in SFAS No. 141, Business Combinations (SFAS 141) and No. 142, Goodwill and Other Intangible Assets (SFAS 142). As a result, the assets and liabilities of Winwell were included in the Company’s March 31, 2006 consolidated balance sheet. The Company reflected the results of operations of Winwell beginning January 27, 2006. The Company recorded the estimated fair values of the assets acquired and liabilities assumed at January 27, 2006, which primarily consisted of oil and gas properties of $219.8 million, asset retirement obligations of $0.5 million, a net deferred tax liability of $78.9 million, and goodwill of $33.5 million. The deferred tax liability recognizes the difference between the historical tax basis of Winwell’s assets and the acquisition cost recorded for book purposes. The recorded book value of the oil and gas properties was increased and goodwill was recorded to recognize this tax basis differential. The purchase price allocation is preliminary and subject to change as additional information becomes available. Management does not expect to make any material changes to the original purchase price allocation.

Also on January 27, 2006, the Company completed the acquisition of certain oil and gas assets pursuant to an Asset Purchase Agreement with Redley Company, made and entered into as of December 14, 2005, as amended, (the Asset Purchase Transaction)(the Stock Purchase Transaction and the Asset Purchase Transaction, collectively the North Louisiana Acquisitions). The aggregate consideration paid in the Asset Purchase Transaction was approximately $86.1 million ($86.2 million after certain closing adjustments). The Company reflected the results of operations of the Asset Purchase Transaction beginning January 27, 2006.

We deposited $15 million in earnest money under the terms of the Stock Purchase Transaction, and $7.5 million under the terms of the Asset Purchase Transaction. The $22.5 million deposit was included in other non-current assets at December 31, 2005. The deposit was applied to the overall purchase price.

Mission Resources Corporation

On July 28, 2005, the Company and Mission Resources Corporation (Mission), a Delaware corporation, completed a two-step merger transaction which resulted in Mission’s merger with and into the Company (the Merger). Total consideration for the shares of Mission common stock was comprised of 60.1% Company common stock and 39.9% cash. Accordingly, consideration paid to Mission stockholders in the Merger consisted of approximately $139.5 million in cash and approximately 19.565 million shares of the Company’s common stock. In addition, all outstanding options to purchase Mission common stock were converted into options to purchase Petrohawk common stock using the exchange ratio of 0.7641 shares of Petrohawk common stock per share of Mission common stock underlying each option. The Company assumed Mission’s long-term debt of approximately $184 million.

The Merger was accounted for using the purchase method of accounting under the accounting standards established in SFAS 141 and SFAS 142. As a result, the assets and liabilities of Mission were included in the Company’s September 30, 2005 consolidated balance sheet. The Company reflected the results of operations of Mission beginning July 28, 2005. The Company recorded the estimated fair values of the assets acquired and liabilities assumed at July 28, 2005, which primarily consisted of oil and gas properties of $606.7 million, derivative liabilities of $29.4 million, asset retirement obligations of $37.7 million, a net deferred tax liability of $134.8 million, and goodwill of $138.9 million. The deferred tax liability recognizes the difference between the historical tax basis of Mission’s assets and the acquisition cost recorded for book purposes. The recorded book value of the oil and gas properties was increased and goodwill was recorded to recognize this tax basis differential. The purchase price allocation is preliminary and subject to change as additional information becomes available. Management does not expect to make any material changes to the original purchase price allocation.

Proforma for North Louisiana Acquisitions and Mission

The Company’s unaudited pro forma results are presented below for the three months ended March 31, 2006 and 2005. The unaudited pro forma results for the three months ended March 31, 2005 have been prepared to illustrate the approximated pro forma effects on the Company’s results of operations under the purchase method of accounting as if the Company had completed the North Louisiana Acquisitions and Mission merger on January 1, 2005. The unaudited pro forma results for the three months ended March 31, 2006 have been prepared to illustrate the approximated pro forma effects on the Company’s results of operations under the purchase method of accounting as if the Company had completed the North Louisiana Acquisitions on January 1, 2006. The unaudited pro forma results do not purport to represent what the results of operations would actually have been if the transactions had in fact occurred on such date or to project the Company’s results of operations for any future date or period.


	Three Months Ended March 31,
	2006		2005
	(In thousands, except per share amounts)
Pro forma:
Oil and gas sales	$	105,848	$	78,210
Net income (loss) available (applicable) to common stockholders		38,269		(51,753	)

Basic earnings (loss) per share	$	0.46	$	(0.85	)
Diluted earnings (loss) per share	$	0.45	$	(0.85	)

3. OIL AND GAS PROPERTIES

The Company uses the full cost method of accounting for its investment in oil and gas properties. Under this method of accounting, all costs of acquisition, exploration and development of oil and gas reserves (including such costs as leasehold acquisition costs, geological expenditures, dry hole costs, tangible and intangible development costs and direct internal costs) are capitalized as the cost of oil and gas properties when incurred. To the extent that capitalized costs of oil and gas properties, net of accumulated depreciation, depletion and amortization, exceed the discounted future net revenues of proved oil and gas reserves net of deferred taxes, such excess capitalized costs would be charged to expense. No such charges were required during the three month periods ending March 31, 2006 and 2005.

4. LONG-TERM DEBT

Long-term debt as of March 31, 2006 and December 31, 2005 consisted of the following:

Senior Revolving Credit Facility

On January 27, 2006, the Company amended its Amended and Restated Senior Revolving Credit Agreement dated as of July 28, 2005, as amended (the Senior Credit Agreement) in connection with the North Louisiana Acquisitions. Pursuant to the amendment, the maximum credit amounts were increased to $600 million and the borrowing base was increased to $400 million. The execution of the amendment by the lenders also constituted a waiver by the lenders permitting the transactions to be completed. In conjunction with the closing of the Gulf of Mexico properties sale, the Senior Credit Agreement’s borrowing base was decreased to $385 million.

Amounts outstanding under the Senior Credit Agreement bear interest at a specified margin over the London Interbank Offered Rate (LIBOR) of 1.25% to 2.00% for Eurodollar loans or at specified margins over the Alternate Base Rate (ABR) of 0.00% to 0.50% for ABR loans. Such margins will fluctuate based on the utilization of the facility. Borrowings under the Senior Credit Agreement are secured by first priority liens on substantially all of the Company’s assets, including equity interest in the Company’s subsidiaries. Amounts drawn on the facility mature on July 28, 2009.

The Senior Credit Agreement requires the Company to maintain certain financial covenants pertaining to minimum working capital levels, minimum coverage of interest expense, and a maximum leverage ratio. The Company may not permit its ratio of total present value of reserves to total debt to be less than 1.5 to 1.0 after March 31, 2005. The Company may not permit its ratio of total debt to EBITDA (as defined in the debt agreement) for the period of four fiscal quarters immediately preceding the date of redetermination for which financial statements are available to be greater than 4.0 to 1.0. In addition, the Company is subject to covenants limiting dividends, and other restricted payments, transactions with affiliates, incurrence of debt, changing of control, asset sales, and liens on properties. At March 31, 2006, the Company is in compliance with all of its debt covenants under the Senior Credit Agreement.

Second Lien Term Loan Facility

On January 27, 2006, the Company amended its Amended and Restated Term Loan Agreement dated as of July 28, 2005, as amended (the Term Loan) in connection with the North Louisiana Acquisitions. At March 31, 2006, the Company had $175 million outstanding under the Term Loan. Pursuant to the amendment, the maximum allowed commitment amount thereunder was increased to $300 million. The Company has the ability to draw down an additional $125 million subject to the approval of the administrative agent under the Term Loan (which is not to be unreasonably withheld) and the additional commitment of the lenders to lend an amount over $50 million.

Amounts repaid under the Term Loan may not be re-borrowed. Amounts outstanding bear interest at a specified margin over the LIBOR rate of 4.50% for Eurodollar loans or at specified margins over the ABR rate of 3.50% for ABR loans. The Company is obligated to repay 1% per annum of the original principal balance beginning on July 28, 2006, with the remaining 96% of the original principal balance due and payable on July 28, 2010.

The Company is subject to certain financial covenants pertaining to minimum asset coverage ratio and a maximum leverage ratio as discussed above under the Senior Credit Agreement. In addition, the Company is subject to covenants limiting dividends and other restricted payments, transactions with affiliates, incurrence of debt, changes of control, asset sales, and liens on properties. At March 31, 2006, the Company is in compliance with all of its debt covenants under the Term Loan.

9⁷/8% Senior Notes

On April 8, 2004, Mission issued $130.0 million of its 9⁷/8% senior notes due 2011 (the Notes). Interest on the notes is payable semi-annually, on each April 1 and October 1, commencing on October 1, 2004. In conjunction with the Merger, the Company assumed these notes. In November 2005, the Company acquired, at market price, $5.5 million face amount of the Notes from an investor. The Company retired those Notes and recognized a gain on extinguishment of debt of approximately $0.1 million.

The purchase method of accounting for the Merger required that the Company record the assets and liabilities acquired at fair value. The Notes were trading at a premium on the merger date, therefore, a $11.1 million premium on the Notes was recorded to reflect the merger date fair value of the Notes on Petrohawk’s balance sheet. The premium will be amortized over the life of the Notes using the effective interest method. The amortization resulted in a $0.4 million reduction of interest expense for the three months ended March 31, 2006. Future amortization will result in a reduction of interest expense.

The Notes contain covenants that, subject to certain exceptions and qualifications, limit the Company’s ability and the ability of certain of its subsidiaries to incur or guarantee additional indebtedness, issue certain types of equity securities, transfer or sale assets, or pay dividends. Additionally, transactions with affiliates, selling stock of a subsidiary, merging or consolidating are subject to qualifications. At March 31, 2006, the Company is in compliance with all of its covenants under the Notes.

The Notes are jointly and severally and fully and unconditionally guaranteed on a senior unsecured basis by all of the Company’s current subsidiaries. Petrohawk Energy Corporation, the issuer of the Notes, has no material independent assets or operations apart from the assets and operations of its subsidiaries.

Debt Issuance Costs

The Company capitalizes certain direct costs associated with the issuance of long-term debt.

In conjunction with the North Louisiana Acquisitions, the Company modified its Term Loan. This modification increased the Company’s borrowing capacity to $300 million and was appropriately treated as an extinguishment of debt for accounting purposes.

At March 31, 2006, the Company has approximately $2.6 million of net debt issuance costs that are being amortized over the lives of the respective debt.

5. ASSET RETIREMENT OBLIGATIONS

If a reasonable estimate of the fair value of an obligation to perform site reclamation, dismantle facilities or plug and abandon wells can be made, the Company records a liability (an asset retirement obligation or ARO) on the consolidated balance sheet and capitalizes the asset retirement cost in oil and gas properties in the period in which the retirement obligation is incurred. In general, the amount of an ARO and the costs capitalized will be equal to the estimated future cost to satisfy the abandonment obligation using current prices that are escalated by an assumed inflation factor up to the estimated settlement date, which is then discounted back to the date that the abandonment obligation was incurred using an assumed cost of funds for the company. After recording these amounts, the ARO is accreted to its future estimated value using the same assumed cost of funds and the additional capitalized costs are depreciated on a unit-of-production basis.

The Company recorded the following activity related to the ARO liability for the three months ended March 31, 2006:

⁽¹⁾

Refer to Note 2, Acquisitions and Divestitures, for more details.

The Company currently plans to plug approximately 50 gross wells in the next twelve months. Accordingly, the Company has classified $1.5 million of the overall $31.2 million liability as a current liability in accounts payable and accrued liabilities at March 31, 2006 compared to $1.1 million at December 31, 2005.

6. COMMITMENTS AND CONTINGENCIES

The Company is a defendant in various legal proceedings arising in the normal course of business. All known liabilities are accrued based on management’s best estimate of the potential loss. While the outcome and impact of such legal proceedings on the Company cannot be predicted with certainty, the Company’s management and legal counsel believe that the resolution of these proceedings through settlement or adverse judgment will not have a material adverse effect on the Company’s consolidated results of operations, financial position or cash flow.

A lawsuit was filed by Andrew A. Roth (Mr. Roth) against the Company, as a nominal defendant, certain of Company’s directors and certain of the Company’s current and former stockholders, including PHAWK, LLC, which alleged violations of Section 16(b) of the Exchange Act of 1934, as amended. The lawsuit sought recovery, on behalf of the Company, of alleged short-swing profits of at least $6.5 million. Mr. Roth filed the lawsuit in the United States District Court for the Southern District of New York on October 31, 2005 as Andrew A. Roth derivatively on behalf of Petrohawk Energy Corporation v. PHAWK, LLC, et. al., and the case was assigned Civil Case Number: 05 CV 9247. Pursuant to an August 1, 2005 demand letter from Mr. Roth, an independent committee of the board of directors of the Company investigated Mr. Roth’s claims prior to the filing of the lawsuit and concluded they had no merit. This case was dismissed by the court on April 19, 2006.

The Company has established reserves for certain legal proceedings. The establishment of a reserve involves an estimation process that includes the advice of legal counsel and subjective judgment of management. Management believes these reserves to be adequate, and does not expect the Company to incur additional losses with respect to those matters in which reserves have been established. However, future changes in the facts and circumstances could result in the actual liability exceeding the estimated ranges of loss and amounts accrued. While the outcome and impact on the Company cannot be predicted with certainty, management believes that the resolution of these proceedings through settlement or adverse judgment will not have a material adverse effect on the consolidated results of operations, financial position or cash flows of the Company.

Prior to the acquisition of Mission by Petrohawk, Mission entered into agreements with a surety company and other third parties. All parties involved agreed to be jointly and severally liable to the surety company for certain liabilities arising under the agreement and limited to approximately $35 million. As of March 31, 2006, there have been no payments made as a result of this agreement.

7. DERIVATIVE ACTIVITIES

Periodically, the Company enters into derivative commodity instruments to hedge its exposure to price fluctuations on anticipated oil and gas production. Under collar arrangements, if the index price rises above the ceiling price, the Company pays the counterparty. If the index price falls below the floor price, the counterparty pays the Company. Under price swaps, the Company is required to make payments to, or receive payments from, the counterparties based upon the differential between a specified fixed price and a price related to those quoted on the New York Mercantile Exchange for each respective period. Under put options, the Company pays a fixed premium to lock in a specified floor price. If the index price falls below the floor price, the counterparty pays the Company net of the fixed premium. If the index price rises above floor price, the Company pays the fixed premium.

At March 31, 2006, the Company had 40 open positions: 16 natural gas price collar arrangements, one natural gas price swap arrangement, four natural gas put options, one crude oil price swap arrangement and 18 crude oil collar arrangements. The Company elected not to designate any positions as cash flow hedges for accounting purposes, and accordingly, recorded the net change in the mark-to-market valuation of these derivative contracts in the consolidated statement of operations.

At March 31, 2006, the Company had a $6.1 million derivative asset, $4.0 million of which is classified as current, and a $58.4 million derivative liability, $31.2 million of which is classified as current. The weighted average of the forward strip prices used to value the derivative liability were $68.92 per barrel of oil (Bbl) and $8.85 per million British thermal unit (Mmbtu) of natural gas.

The Company recorded a net derivative gain of $24.8 million for the three months ended March 31, 2006.

At March 31, 2005, the Company had 78 open positions: 36 natural gas price collar arrangements, eight natural gas price swap arrangements, six crude oil price swap arrangements and 28 crude oil collar arrangements. The Company had a $21.2 million derivative liability, $7.8 million of which is classified as current. In addition, the Company recorded a net derivative loss of $28.7 million for the three months ended March 31, 2005.

8. STOCKHOLDERS’ EQUITY

In connection with the North Louisiana Acquisitions, on February 1, 2006, the Company issued and sold 13 million shares of its common stock for $14.50 per share, for an aggregate offering amount of approximately $188.5 million. The Company received approximately $180.4 million in net proceeds from the offering. Contemporaneously with the offering, the Company agreed to repurchase, and EnCap agreed to sell, approximately 3.3 million shares for $46.2 million, which represents the price equal to the net proceeds received for those 3.3 million shares by the Company from the private offering. See Note 9 Related Party Transactions below. The shares of common stock were privately placed in the offering and were not registered under the Securities Act of 1933, as amended (the Act), or any state securities laws. The common stock was offered and sold pursuant to the private placement exceptions from registration provided by Regulation D, Rule 506, under Section 4(2) of the Act and Regulation S of the Act. Shares of the common stock were offered and sold only to “accredited investors” (as defined in Rule 501(a) of the Act) and non-United States persons pursuant to the offers and sales that occur outside the United States within the meaning of Regulation S under the Act. The placement agents for this offering received a cash fee equal to approximately $7.7 million as compensation for services provided in connection with the offering and to reimburse them for certain expenses.

Pursuant to a related registration rights agreement by the Company and for the benefit of the purchasers in the aforementioned private offering, the Company agreed to file and cause to be declared effective by the SEC a registration statement covering resales of shares of the Company’s common stock sold in this offering as promptly as reasonably practical and in any event within 75 days after the closing of the offering. These shares were registered pursuant to the registration rights agreement by the Company on March 20, 2006 in conjunction with the filing of a Registration Statement on Form S-3 (No. 33-132565).

During the second and third quarters of 2005 and in conjunction with the Merger with Mission Resources, the Company filed two Registration Statements on Form S-8 and one Registration Statement on Form S-4. The first Registration Statement on Form S-8 was filed to register an additional 3.5 million shares of the Company’s common stock under stock options granted pursuant to the Second Amended and Restated 2004 Employee Incentive Plan and an additional 0.2 million shares of the Company’s common stock pursuant to the Second Amended and Restated 2004 Non-Employee Director Incentive Plan. The second Registration Statement on Form S-8 was filed to register approximately 3.85 million shares of common stock of the Company for issuance pursuant to employee benefit plans and nonstatutory stock option agreements of Mission which the Company agreed to assume under the term of the merger agreement. The Company also increased its authorized number of common shares to 125 million from 75 million.

9. RELATED PARTY TRANSACTIONS

The Company entered into a stock purchase agreement with EnCap Investments, L.P. and certain of its affiliates (collectively EnCap), pursuant to which the Company agreed to repurchase, and EnCap agreed to sell, approximately 3.3 million shares of the Company’s common stock held by EnCap at a price per share equal to the net proceeds per share that the Company received from the private offering. The 3.3 million shares were repurchased for $46.2 million, which represents the price equal to the net proceeds received for those 3.3 million shares by the Company from the private offering. As of March 31, 2006 the Company had retired the shares.

10. NET EARNINGS/ (LOSS) PER COMMON SHARE

Basic earnings (loss) per share (EPS) is calculated by dividing net income by the weighted average number of shares of common stock (other than unvested restricted stock) outstanding during the period. Diluted earnings per share incorporates the dilutive impact of common stock equivalents (using the treasury stock method) and unvested restricted stock.

The following is the calculation of basic and diluted weighted average shares outstanding and EPS for the three months ended March 31, 2006 and 2005:

12. SUBSEQUENT EVENTS

On April 21, 2006, the Company and KCS Energy, Inc. (KCS) announced that they have entered into a definitive agreement to merge the companies and create a combined oil and gas exploration and production company. The combined company will continue to be known as Petrohawk Energy Corporation and will be headquartered in Houston, Texas.

Under the terms of the merger agreement, KCS stockholders will receive $9.00 per share in cash and 1.65 shares of Petrohawk common stock for each share of KCS common stock they own. This represents consideration to KCS stockholders of $31.41 per share based on the closing price of Petrohawk shares on April 20, 2006. KCS stock options will convert into Petrohawk options pursuant to the terms of the merger agreement. Following the transaction, KCS stockholders will own approximately 50% of the combined company.

Mr. Floyd C. Wilson will continue his role as the Company’s Chairman, President and CEO. KCS’s James W. Christmas will serve as Vice Chairman and William N. Hahne as Executive Vice President and Chief Operating Officer of the combined company. Following the completion of the merger, the Company will have nine directors, five nominated by Petrohawk, including Mr. Wilson, and four nominated by KCS, including Mr. Christmas.

The transaction is subject to the approval of the stockholders of Petrohawk and KCS. The boards of directors of both companies have unanimously approved the merger agreement, which is subject to customary conditions, including approval of listing of the Petrohawk shares to be issued in the merger on NASDAQ and regulatory approvals. The transaction is expected to be completed during the third quarter of 2006.

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

The following review of operations for the three months ended March 31, 2006 and 2005 should be read in conjunction with our Consolidated Financial Statements and the Notes included in this Form 10-Q and with the Consolidated Financial Statements, Notes and Management’s Discussion and Analysis included in the Petrohawk Energy Corporation Form 10-K, as amended for the year-ended December 31, 2005.

Overview

We are an independent oil and gas company engaged in the acquisition, development, production and exploration of oil and gas properties located in North America. Our properties are concentrated in the Permian Basin, East Texas, North Louisiana, Gulf Coast, South Texas, Anadarko and Arkoma regions. We have increased our proved reserves and production principally through acquisitions in conjunction with an active drilling program.

We focus on maintaining a balanced, geographically diverse portfolio of long-lived, lower risk reserves along with shorter lived, higher margin reserves. We believe that this balanced reserve mix provides a diversified cash flow foundation to fund our development and exploration drilling program.

Our financial results depend upon many factors, particularly the price of oil and gas and our ability to market our production. Commodity prices are affected by changes in market demands, which are impacted by overall economic activity, weather, pipeline capacity constraints, inventory storage levels, basis differentials and other factors. As a result, we cannot accurately predict future oil and gas prices, and therefore, we cannot determine what effect increases or decreases will have on our capital program, production volumes and future revenues. In addition to production volumes and commodity prices, finding and developing sufficient amounts of oil and gas reserves at economical costs are critical to our long-term success.

In the first three months of 2006, we produced 12.2 billion cubic feet of natural gas equivalent (Bcfe) compared to production of 4.8 Bcfe for the comparable period of the prior year. Natural gas production was 8.6 billion cubic feet (Bcf) and oil production was 596 thousand barrels of oil (Mbbls) for the first three months of 2006. Oil and natural gas production in the current period increased 7.4 Bcfe from the same period in 2005. This increase was primarily attributable to the acquisition of Mission in July of 2005 (5.2 Bcfe) and the North Louisiana Acquisitions in January of 2006 (1.0 Bcfe). The remaining increase in production was due to our continued drilling success as we drilled 66 wells during the quarter, 63 of which were successful for a success rate of 95%. We reported oil and gas revenues for the three months ended March 31, 2006 of $103.0 million. This represents an increase of $70.7 million as compared to the same period of the prior year. The increase in our production and oil and natural gas revenues was principally through acquisitions and increases in our realized commodity prices. We focus on properties within our core operating areas that have significant proved reserve components and which we believe have additional development and exploration opportunities.

In the first three months of 2006, natural gas prices were higher than the comparable period of the prior year and our financial results reflect their impact. Our realized natural gas equivalent price increased $1.72 per thousand cubic feet of natural gas equivalent (Mcfe), or 26%, to $8.40 compared to the $6.68 per Mcfe realized in the same period of the prior year. Commodity prices are determined by factors that are outside of our control. Historically, commodity prices have been volatile and we expect them to remain volatile. Commodity prices are affected by changes in market demands, overall economic activity, weather, pipeline capacity constraints, storage levels, basis differentials and other factors. As a result, we cannot accurately predict future natural gas and crude oil prices, and therefore, cannot accurately predict revenues.

We believe that our cash flow from operations and other financial resources will provide us with the ability to fully develop our existing properties, to finance our current exploration projects and to pursue new acquisition opportunities.

On April 21, 2006, we entered into a definitive agreement to merge with KCS Energy, Inc. (KCS). The combined company will continue to be known as Petrohawk Energy Corporation and will be headquartered in Houston, Texas. On an estimated pro forma basis, we will have estimated proved reserves of approximately one trillion cubic feet of natural gas equivalents of which approximately 68% would be classified as proved developed and approximately 82% would be natural gas.

Under the terms of the agreement, KCS stockholders will receive $9.00 per share in cash and 1.65 shares of Petrohawk common stock for each share of KCS common stock they own. This represents consideration to KCS stockholders of $31.41 per share based on the closing price of Petrohawk shares on April 20, 2006. Following the transaction, KCS stockholders will own approximately 50% of the combined company.

Capital Resources and Liquidity

We funded our capital program exclusive of acquisitions with cash flows from operations. The North Louisiana Acquisitions were funded through the issuance of common stock and additional borrowings under our debt facilities. Proceeds from the divestiture of our Gulf of Mexico properties were used to reduce the revolving credit facility. Operating cash flow fluctuations are substantially driven by commodity prices and changes in our production volumes. Prices for natural gas and crude oil have historically been subject to seasonal influences characterized by peak demand and higher prices in the winter heating season; however, the impact of other risks and uncertainties have influenced prices throughout recent years. Working capital is substantially influenced by these variables. Our working capital deficit at March 31, 2006 is primarily driven by our current portion of the unrealized mark-to-market derivative liability. Fluctuations in cash flow may result in an increase or decrease in our capital and exploration expenditures. See below for additional discussion and analysis of cash flow.

Net increase in cash and cash equivalents is summarized as follows:


	Three Months Ended March 31,
	2006			2005
	*(In thousands)*
Cash flows provided by operating activities	$	53,921		$	20,557
Cash flows (used in) provided by investing activities		(239,998	)		7,688
Cash flows provided by (used in) financing activities		176,808			(27,546	)

Net (decrease) increase in cash and cash equivalents	$	(9,269	)	$	699

Operating Activities. Net cash provided by operating activities for the three months ended March 31, 2006 increased $33.4 million from the same period in 2005. This increase was primarily due to the increase in our net income as a result of our increase in oil and gas revenues due to higher commodity prices and an increase in sales volumes primarily attributable to the Mission acquisition and the North Louisiana Acquisitions. Average realized prices for the three months increased 26% from $6.68 per Mcfe in 2005 to $8.40 per Mcfe in 2006. Production volumes for the three months ended March 31, 2006 increased from 4.8 Bcfe in 2005 to 12.2 Bcfe in 2006.

Investing Activities. The primary driver of cash used in investing activities was capital spending, inclusive of acquisitions and net of dispositions. Cash used in investing activities increased to $240.0 million from cash provided by operations of $7.7 million for the same period in 2005.

On January 27, 2006, we completed the acquisition of all of the issued and outstanding common stock of Winwell pursuant to a Stock Purchase Agreement with Winwell and all of its shareholders made and entered into as of December 14, 2005 (the Stock Purchase Transaction). The aggregate consideration paid in the Stock Purchase Transaction was approximately $208 million in cash after certain closing adjustments. Also on January 27, 2006, we completed the acquisition of assets pursuant to an Asset Purchase Agreement with Redley, made and entered into as of December 14, 2005, as amended, (the Asset Purchase Transaction). The aggregate consideration paid in the Asset Purchase Transaction was approximately $86 million in cash after certain closing adjustments. We deposited $15 million in earnest money under the terms of the Stock Purchase Transaction, and $7.5 million under the terms of the Asset Purchase Transaction. The $22.5 million deposit was included in other non-current assets at December 31, 2005. The deposit and interest earned was applied to the overall purchase price.

We closed the previously announced $52.5 million divestment of substantially all of our properties in the Gulf of Mexico on March 21, 2006. The net proceeds received in this transaction were used to pay down a portion of our long-term debt.

During the first quarter of 2005, we completed the acquisition of Proton Oil & Gas Corporation for $52.6 million in cash and the disposition of certain royalty interest properties previously acquired from Wynn-Crosby Energy, Inc. and certain of its affiliates for approximately $78.5 million in cash. These transactions had effective dates of January 1, 2005.

We have established a capital budget of $210 million for 2006 which is expected to be funded primarily from cash flows from operations. We establish the budget for these amounts based on our current estimate of future commodity prices. Due to the volatility of commodity prices our budget may be periodically adjusted. We expect to be operating eight to ten drilling rigs during the remainder of 2006 and expects that five to ten non-operated rigs will be running at all times. Significant ongoing activities will occur in South Texas, East Texas, North and South Louisiana, the Permian Basin and the Arkoma Basin.

Financing Activities. Net cash flows provided by financing activities were $176.8 million for the three months ended March 31, 2006 compared to a net cash use of $27.5 million for the three months ended March 31, 2005. Cash flows provided by financing activities in 2006 were the result of increased borrowings, primarily to fund acquisitions. Financing activities in 2006 included $4.5 million of cash paid on settled derivative contracts that were acquired in conjunction with our acquisition activity compared with $1.3 million in 2005.

We strive to maintain excess availability under our senior revolving credit facility. Excess cash flow and non-core asset sales are used to repay debt to the extent possible. During the first quarter of 2006, the Company had net borrowings of $50 million primarily due to the capital requirements of the closing of the North Louisiana Acquisitions.

During the first quarter of 2006, we paid our previously accrued fourth quarter of 2005 dividends of $0.1 million on our 8% cumulative convertible preferred stock. We have accrued the first quarter 2006 dividend of $0.1 million. During the first quarter of 2005, we paid the first quarter dividend of $0.1 million.

Contractual Obligations

We have no material long-term commitments associated with our capital expenditure plans or operating agreements. Consequently, we believe we have a significant degree of flexibility to adjust the level of such expenditures as circumstances warrant. Our level of capital expenditures will vary in future periods depending on the success we experience in our acquisition, developmental and exploration activities, oil and gas price conditions and other related economic factors. Currently no sources of liquidity or financing are provided by off-balance sheet arrangements or transactions with unconsolidated, limited-purpose entities. As previously discussed, we have entered into an agreement with KCS to merge the companies. The transaction is currently expected to close during the third quarter of this year.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operation are based upon the consolidated financial statements, which have been prepared in accordance with accounting principals generally accepted in the United States of America. Preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. There have been no changes to our critical accounting policies from those described in the 2005 Form 10-K, as amended.

Results of Operations

Quarters ended March 31, 2006 and 2005

We reported net income of $32.9 million for the three months ended March 31, 2006 compared to a net loss of $14.3 million for the comparable period in 2005. The increase in net income of $47.2 million from prior year was primarily driven by an increase in sales volumes due to our acquisition activities, higher realized prices and a decrease in our unrealized loss on derivative contracts.

For the three months ended March 31, 2006, oil and gas sales increased $70.7 million from the comparable period in 2005, to $103.0 million. The increase for the three months is primarily attributable ($50 million) to an increase in production as a result of the acquisition of Mission in July of 2005 (5.2 Bcfe) and the closing of the North Louisiana Acquisitions (1.0 Bcfe). Higher commodity prices led to an approximate $21 million increase in revenues from the comparable period in 2005 as our realized average price per Mcfe for the three month period increased $1.72 to $8.40 in 2006 from $6.68 in 2005.

Lease operating expenses increased $7.0 million for the three months ended March 31, 2006 as compared to the same period in 2005. This increase is primarily due to the increase in overall production of 7.4 Bcfe as a result of our recent acquisition activities. On a per unit basis, lease operating expense remained flat at $0.94 per Mcfe as we have been able to successfully integrate our acquisitions into our overall business while maintaining our focus on lease operating expenses.

Taxes other than income increased $6.0 million for the three months ended March 31, 2006 as compared to the same period in 2005 due to a corresponding increase in oil and gas revenues. The largest portion of taxes other than income are production and severance taxes which are generally assessed as a percentage of gross oil and natural gas sales. On a per unit basis, taxes other than income increased $0.20 per Mcfe to $0.68 per Mcfe in 2006 as compared to $0.48 per Mcfe during the same period in 2005. As a percentage of oil and gas sales, taxes other than income were approximately 8% and 7% for the quarters ended March 31, 2006 and 2005, respectively.

General and administrative expenses for the three months ended March 31, 2006 increased $2.7 million to $6.0 million compared to the same period in 2005. This increase was primarily due to the acquisition of Mission in July of 2005. Employee headcount almost doubled due to the Company leveraging the hiring opportunity of Mission employees to appropriately staff the Company. Additionally, office expenses increased from prior year due primarily to an increase in office rent associated with the leasing of additional space to accommodate the employees from Mission. In January 2005, we made the decision to bring the previously outsourced accounting function back in house, but did not see the full effect of that in the first quarter of 2005. The decrease in the outsource fee has been partially offset by an increase in costs associated with an internal accounting department. General and administrative expenses have decreased significantly on a per Mcfe basis from $0.68 per Mcfe for the three months ended March 31, 2005 to $0.49 per Mcfe for the comparable period of 2006 as production increases have outpaced our administrative expenses. We focus on reducing general and administrative expenses as a part of our overall business integration plan to the extent possible.

Depletion expense increased $26.2 million from the same period in 2005 to $36.8 million for the three months ended March 31, 2006. Depletion for oil and gas properties is calculated using the unit of production method, which amortizes the capitalized costs associated with the evaluated properties based on the ratio of production volume for the current period to total remaining reserve volumes for the evaluated properties. On a per unit basis, depletion expense increased $0.82 per Mcfe to $3.00 per Mcfe. This increase is primarily due to the North Louisiana Acquisitions and partially offset by the Gulf of Mexico property divestiture.

We enter into derivative commodity instruments to hedge our exposure to price fluctuations on our anticipated oil and gas production. At March 31, 2006, we had 40 open positions: 16 natural gas price collar arrangements, one natural gas price swap arrangement, four natural gas put options, one crude oil price swap arrangement and 18 crude oil collar arrangements. Consistent with 2005, we have elected not to designate any positions as cash flow hedges for accounting purposes, and accordingly, we recorded the net change in the mark-to-market valuation of these derivative contracts in the consolidated statement of operations. At March 31, 2006, we had a net derivative liability of $52.3 million and recognized a net derivative gain of $24.8 million for the three months ended March 31, 2006 compared to a net derivative loss of $28.7 million in the prior year. This increase of $53.5 million from the prior year is primarily due to the decrease in forward commodity prices during the first quarter of 2006 as compared to commodity prices at December 31, 2005.

Interest expense and other for the first quarter of 2006 increased $5.7 million from the same period in 2005. This increase is primarily due to the additional debt incurred in conjunction with the acquisition of Mission and the closing of the North Louisiana Acquisitions as our long-term debt excluding the premium recorded on our 9⁷/8% Senior Notes and our deferred premiums on derivatives increased from $213.0 million at March 31, 2005 to $534.5 million at March 31, 2006.

Income tax expense for the first quarter of 2006 increased $27.9 million from the prior year. The increase from prior year is primarily due to our pre-tax net income of approximately $52.2 million for the first quarter of 2006 compared to a pre-tax net loss of $23.0 million for the first quarter of 2005.

Recently Issued Accounting Pronouncements

We discuss recently adopted and issued accounting standards in Item 1. Consolidated Financial Statements Note 1, Financial Statement Presentation.

Item 3. Quantitative and Qualitative Disclosure about Market Risk

We are exposed to various risks including energy commodity price risk. We have designed our hedging policy to reduce the risk of price volatility for our production in the natural gas and crude oil markets. Our hedging arrangements apply to only a portion of our current and anticipated production and provide only partial price protection against declines in oil and gas prices. We are exposed to market risk on our open contracts, to the extent of changes in market prices of oil and gas. However, the market risk exposure on these hedged contracts is generally offset by the gain or loss recognized upon the ultimate sale of the commodity that is hedged. Further, if our counterparties defaulted, this protection might be limited as we might not receive the benefits of the hedges. Please refer to Item 1. Consolidated Financial Statements Note 7, Derivative Activities for the required disclosures.

We are also exposed to market risk related to adverse changes in interest rates. Our interest rate risk exposure results primarily from short-term rates, which are LIBOR and ABR based.

Item 4. Controls and Procedures

As of the end of the current reported period covered by this report, the Company carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the Company’s disclosure controls and procedures pursuant to Rule 13a-15 of the Securities Exchange Act of 1934 (the Exchange Act). Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures are effective, in all material respects, with respect to the recording, processing, summarizing and reporting, within the time periods specified in the Commission’s rules and forms, of information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act.

There were no changes in the Company’s internal control over financial reporting that occurred during the most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

In connection with the North Louisiana Acquisitions, on February 1, 2006, the Company issued and sold 13 million shares of its common stock for $14.50 per share, for an aggregate offering amount of approximately $188.5 million. The Company received approximately $180.4 million in net proceeds from the offering. Contemporaneously with the offering, the Company agreed to repurchase, and EnCap agreed to sell, approximately 3.3 million shares for $46.2 million, which represents the price equal to the net proceeds received for those 3.3 million shares by the Company from the private offering. The shares of common stock were privately placed in the offering and were not registered under the Securities Act of 1933, as amended (the Act), or any state securities laws. The common stock was offered and sold pursuant to the private placement exceptions from registration provided by Regulation D, Rule 506, under Section 4(2) of the Act and Regulation S of the Act. Shares of the common stock were offered and sold only to “accredited investors” (as defined in Rule 501(a) of the Act) and non-United States persons pursuant to the offers and sales that occur outside the United States within the meaning of Regulation S under the Act. The placement agents for this offering received a cash fee equal to approximately $7.7 million as compensation for services provided in connection with the offering and to reimburse them for certain expenses.

Pursuant to a related registration rights agreement by the Company and for the benefit of the purchasers in the aforementioned private offering, the Company agreed to file and cause to be declared effective by the SEC a registration statement covering resales of shares of the Company’s common stock sold in this offering as promptly as reasonably practical and in any event within 75 days after the closing of the offering. These shares were registered pursuant to the registration rights agreement by the Company on March 20, 2006 in conjunction with the filing of a registration statement on Form S-3 (No. 33-132565).

Issuer Purchases of Equity Securities

On January 26, 2006, the Company entered into a stock purchase agreement with EnCap Investments, L.P. and certain of its affiliates (collectively EnCap), pursuant to which the Company agreed to repurchase, and EnCap agreed to sell, approximately 3.3 million shares of the Company’s common stock held by EnCap at a price per share equal to the net proceeds per share that the Company received from the private offering (see table below). The stock purchase agreement was effective as of January 10, 2006.
