PETROHAWK ENERGY CORPORATION

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 disclosed in its Report on Form 10-K for the preceding fiscal year, as amended and filed with the Securities and Exchange Commission (SEC). Please
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.

On July 12, 2006, the Company
completed its previously announced merger with KCS Energy, Inc. (KCS). Please refer to Note 2, Acquisitions and Divestitures, for more details on KCSs merger with and into the Company and various related transactions.

Recently Issued Accounting Pronouncements

During
July 2006, the Financial Accounting Standards Board (FASB) issued Financial Interpretation (FIN) No. 48, Accounting for Uncertainty in Income Taxesan Interpretation of FASB Statement No. 109 (FIN 48). FIN 48 addresses the
accounting for uncertainty in income taxes recognized in an enterprises financial statements in accordance with Statement of Financial Accounting Standards (SFAS) No. 109, Accounting for Income Taxes. FIN 48 prescribes specific
criteria for the financial statement recognition and measurement of the tax effects of a position taken or expected to be taken in a tax return. This interpretation also provides guidance on derecognition of previously recognized tax benefits,
classification of tax liabilities on the balance sheet, recording interest and penalties on tax underpayments, accounting in interim periods, and disclosure requirements. FIN 48 is effective for fiscal periods beginning after December 15, 2006.
The Company is currently assessing the impact, if any, that the adoption of FIN 48 will have on its financial statements.

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 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 results.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)(Continued)



As allowed by SFAS 123(R), the Company utilizes 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 nine
months ended September 30, 2006 and 2005 are disclosed in the following table:

The weighted average grant date fair value of the shares granted during the nine month period ended September 30, 2006 was $18.2 million. At September 30, 2006, the unrecognized compensation expense related to non-vested
restricted stock totaled $13.0 million and will be recognized on a straight line basis over the weighted average remaining vesting period of 2.1 years. In conjunction with the KCS merger, KCS restricted stock was converted into 0.6 million
shares of Petrohawk restricted stock.

2. ACQUISITIONS AND DIVESTITURES

KCS Energy, Inc.

On April 21, 2006, the Company and KCS announced they had entered into a
definitive agreement to merge the companies. This merger was consummated on July 12, 2006 and was consistent with managements goals of acquiring properties within the Companys core operating areas that have a significant proved
reserve component and which management believes have additional development and exploration opportunities.

Upon the closing of the merger,
KCS stockholders became entitled to receive a combination of $9.00 cash and 1.65 shares of Petrohawk common stock for each share of KCS common stock. At the time of the merger, there were 50.0 million shares of KCS common stock outstanding that
converted into 82.6 million shares of Petrohawk common stock. Total consideration for the shares of KCS common stock was comprised of approximately $1.1 billion of Petrohawk common stock, calculated based on the five day average of
Petrohawks common stock around the merger announcement date, or $13.44, approximately $450 million of cash and the assumption of $275 million of KCS debt. In addition, all outstanding options to purchase KCS common stock were converted into
options to purchase Petrohawk common stock using an exchange ratio of approximately 2.3706 shares of Petrohawk common stock to one share of KCS common stock.

The merger 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 KCS were included in the Companys September 30, 2006 consolidated balance sheet. The Company reflected the results of operations of KCS beginning
July 12, 2006. The Company recorded the estimated fair values of the assets acquired and liabilities assumed at July 12,

2006, which primarily consisted of oil and gas properties of $1.6 billion, asset retirement obligations of $15.1 million, a deferred income tax liability of
$421.6 million, a deferred income tax asset of $49.1 million and goodwill of $767.1 million. The deferred income tax liability recognizes the difference between the tax basis and the fair value of the acquired oil and gas properties. The recorded
book value of the oil and gas properties was increased and goodwill was recorded to recognize this tax basis differential. The deferred income tax asset pertains to net operating loss carry-forwards and alternative minimum tax credits in the amounts
of $44 million, net of tax, and $5.1 million, respectively. 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.

Goodwill represents the excess of the purchase price over the estimated fair value of the assets acquired net
of the fair value of liabilities assumed in the acquisition. SFAS 142 requires that intangible assets with indefinite lives, including goodwill, be evaluated on an annual basis for impairment or more frequently if an event occurs or circumstances
change that could potentially result in an impairment.

The impairment test requires the allocation of goodwill and all other assets and
liabilities to reporting units. The reporting unit used by the Company for testing will be the entire company. If the fair value of the reporting unit is less than the book value (including goodwill) then goodwill is reduced to its implied fair
value and the amount of the writedown is charged against earnings.

The Company completed its annual impairment review during the third
quarter of 2006. No impairment was deemed necessary. Downward revisions of estimated reserves or production, increases in estimated future costs or decreases in oil and gas prices could lead to an impairment of all or a portion of the Companys
goodwill in future periods.

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). These proceeds were recorded as a
decrease to the Companys full cost pool. The transaction had an effective date of January 1, 2006.

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). The aggregate consideration paid was approximately $208 million in cash after certain closing adjustments.

The Winwell
acquisition 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 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
from Redley Company, Burris Run Company and Red Clay Minerals (together with the Winwell acquisition, the North Louisiana Acquisitions). The aggregate consideration paid in this transaction was approximately $86.1 million ($86.2 million after
certain closing adjustments). The Company reflected the results of operations of the acquired assets beginning January 27, 2006.

The
Company deposited $15 million in earnest money in connection with the Winwell acquisition, and $7.5 million in connection with the asset acquisition. The $22.5 million in deposits were included in other non-current assets at December 31, 2005
and applied to the overall purchase price in January 2006.

Mission Resources Corporation

On July 28, 2005, the Company and Mission Resources Corporation (Mission), completed a two-step merger transaction which resulted in Missions
merger with and into the Company. 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 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 Mission 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 income tax liability of $134.8 million, and goodwill of $138.9 million. The deferred income 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.

Pro forma Results of Operations for the KCS and Mission Mergers

The Companys unaudited pro forma results of
operations for the three and nine months ended September 30, 2006 and 2005 are presented below 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 KCS and Mission mergers on January 1, 2005. The unaudited pro forma results of operations 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.

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 depletion 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. Full cost
companies must use the prices in effect at the end of each accounting quarter to calculate the ceiling test value of their reserves. However, subsequent commodity price increases may be utilized to calculate the ceiling value and reserves. At
September 30, 2006, the ceiling test value of the Companys reserves was calculated based upon quoted market prices of $4.18 per Mcf for Henry Hub gas and $59.38 per barrel for West Texas Intermediate oil, adjusted for market
differentials. Using these prices, the Companys net book value of oil and gas properties would have exceeded the ceiling amount by approximately $579.0 million (net of tax) at September 30, 2006. However, subsequent to quarter end, the
market price for Henry Hub gas and West Texas Intermediate oil increased significantly. As a consequence, prior to October 31, 2006, the Company elected to use prices on October 31, 2006, which were $6.98 per Mcf for Henry Hub gas and
$58.73 per barrel for West Texas Intermediate, adjusted for basis differentials. Utilizing these prices, the Companys net book value of oil and gas properties would not have exceeded the ceiling amount. As a result of the increase in the
ceiling amount using the subsequent prices, the Company has not recorded a write down of its oil and gas property costs. Decreases in product price levels, as well as changes in production rates, levels of reserves, the evaluation of costs excluded
from amortization, future development costs, and service costs and other factors could result in significant future ceiling test impairments.

Senior Revolving Credit Facility

In connection with the KCS merger, the Company amended and restated its Amended and Restated Senior Revolving Credit Agreement dated July 28, 2005. The agreement provides for a $1 billion facility with a
borrowing base that will be redetermined on a semi-annual basis. The Company and the lenders each have the right to one annual interim unscheduled redetermination to adjust the borrowing base based on the Companys oil and gas properties,
reserves, other indebtedness and other relevant factors. At September 30, 2006, the borrowing base was $700 million. The Company expects the borrowing base to be increased to $750 million during the fourth quarter of 2006 based upon the
completion of the redetermination process currently in progress. Amounts outstanding bear interest at specified margins over LIBOR of 1.00% to 1.75% for Eurodollar loans or at specified margins over ABR of 0.00% to 0.50% for ABR loans. Such margins
fluctuate based on the utilization of the facility. Borrowings are secured by first priority liens on substantially all of the Companys assets, including pursuant to the terms of the Second Amended and Restated Guarantee and Collateral
Agreement, all of the assets of, and equity interest in, the Companys subsidiaries. Amounts drawn down on the facility will mature on July 12, 2010.

The revolving credit facility contains customary financial and other covenants, including minimum working capital levels, minimum coverage of interest expense, and a maximum leverage ratio. 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 September 30, 2006, the Company is in compliance with all of
its debt covenants under the revolving credit facility.

71/8% Senior Notes

Upon effectiveness of the KCS merger, the Company assumed
(pursuant to the Second Supplemental Indenture relating to the 71/8Notes, also referred to as the 2012 Notes),
and subsidiaries of the Company guaranteed (pursuant to the Third Supplemental Indenture relating to such notes), all the obligations (approximately $275 million) of KCS under the 2012 Notes and the Indenture dated April 1, 2004 (the 2012
Indenture) among KCS, U.S. Bank National Association, as trustee, and the subsidiary guarantors named therein, which governs the terms of the 71/8% senior notes due 2012. The 2012 Notes are guaranteed on an
unsubordinated, unsecured basis by all of the Companys current subsidiaries, including the subsidiaries of KCS that the Company acquired in the KCS merger. Interest on the 2012 Notes is payable semi-annually, on each April 1 and
October 1. At any time prior to April 1, 2007, the Company may redeem up to 35% of the aggregate original principal amount of the 2012 Notes, using the net proceeds of equity offerings, at a redemption price equal to 107.125% of the
principal amount of the 2012 Notes, plus accrued and unpaid interest. On or after April 1, 2008, the Company may redeem all or a portion of the 2012 Notes at a redemption price equal to 100% of the principal amount plus accrued and unpaid
interest, if any, plus a specified premium which decreases annually from 3.568% in 2008 to 0% in 2010 and thereafter.

The
2012 Indenture contains a provision requiring the Company to offer to purchase the 2012 Notes at 101% of face value in the event of a change of control (as defined in the 2012 Indenture). Certain 2012 Note Holders have alleged that the KCS merger
constitutes a change of control as set forth in the 2012 Indenture. Based upon consultation with counsel, Petrohawk does not believe such a change of control has occurred. See Note 6, Commitments and Contingencies for more details.

91/8% Senior Notes

On July 12, 2006, the Company consummated its private
placement of the 91/8% senior notes, also referred to as the 2013 Notes pursuant to an Indenture dated as of July 12, 2006 (2013 Indenture) and the First Supplemental Indenture to the 2013 Notes (the 2013 First
Supplemental Indenture), among the Company, the Companys subsidiaries named therein as guarantors, and U.S. Bank National Association, as trustee. The 2013 Notes were issued at 98.735% of the face amount for gross proceeds of approximately
$642.0 million, before estimated offering expenses and the initial purchasers discount. The Company applied a portion of the net proceeds from the sale of the 2013 Notes to fund the cash consideration paid by the Company to the KCS
stockholders in connection with the KCS merger and purchase of the 2011 Notes in connection with the Companys tender offer.

The 2013 Notes bear interest at the rate of 9.125% per annum, payable semi-annually on January 15 and July 15 of each year, commencing January 15, 2007. The 2013 Notes mature on July 15, 2013. The 2013 Notes are
senior unsecured obligations of the Company and rank equally with all of its current and future senior indebtedness, including the 2012 Notes. The 2013 Notes rank effectively subordinate to the Companys secured debt to the extent of the
collateral, including secured debt under the revolving credit facility, and senior to any future subordinated indebtedness. The 2013 Notes are jointly and severally guaranteed on a senior unsecured basis by the Companys subsidiaries,
including, pursuant to the 2013 First Supplemental Indenture, the KCS subsidiaries acquired in the KCS merger.

On or before July 15,
2009, the Company may redeem up to 35% of the aggregate principal amount of the 2013 Notes with the net cash proceeds of certain equity offerings at a redemption price of 109.13% of the principal amount thereof plus accrued interest and unpaid
interest to the redemption date provided that: (i) at least 65% in aggregate principal amount of the 2013 Notes originally issued under the 2013 Indenture remain outstanding immediately after the occurrence of such redemption (excluding 2013
Notes held by the Company and its subsidiaries); and (ii) each such redemption must occur within 90 days of the date of the closing of the related equity offering.

In addition, on or before July 15, 2010, the Company may redeem all or part of the 2013 Notes upon not less than 30 nor more than 60 days notice, at a redemption price equal to the sum of (i) the
principal amount thereof, plus (ii) accrued and unpaid interest, if any, to the redemption date, plus (iii) the make whole premium at the redemption date.

On or after July 15, 2010, the Company may redeem some or all of the 2013 Notes at any time. If any of the 2013 Notes are redeemed during any 12-month period beginning on July 15 of the year indicated below,
the Company must pay the following redemption prices (expressed as percentages of principal amount) plus accrued and unpaid interest thereon, if any, to the applicable redemption date:



|     |  |           
|---- |  | ----------
|Year |  | Percentage
|2010 |  | 104.563   
|2011 |  | 102.281   
|2012 |  | 100.000   

The Company may be required to offer to repurchase the 2013 Notes at a purchase price of 101% of
the principal amount, plus accrued and unpaid interest, if any, to the redemption date, in the event of a change of control (as defined in the 2013 Indenture). Additionally, the Company may be required to offer to all holders of the 2013 Notes the
repurchase of the 2013 Notes and to the extent required by the terms thereof, all holders of other indebtedness (as defined in the 2013 Indenture) that is pari passu with the 2013 Notes (at a purchase price

of 100% of the principal amount or accreted value in the case of any such other pari passu indebtedness issued with a significant original issue
discount) plus accrued and unpaid interest, if any, to the date of purchase, in the event net proceeds from assets sales are not applied as required by the 2013 Indenture.

The 2013 Indenture contains covenants that, among other things, restrict or limit the ability of the Company and the guarantors to: (i) borrow
money; (ii) pay dividends on stock; (iii) purchase or redeem stock or subordinated indebtedness; (iv) make investments; (v) create liens; (vi) enter into transactions with affiliates; (vii) sell assets; and
(viii) merge with or into other companies or transfer all or substantially all of the Companys assets. Additionally, the Indenture covering the 2013 Notes contains a provision which provides for a rate increase of 1/8 of one percent if
the Company refinances any part of its 2012 Notes on or before July 11, 2007.

On July 27, 2006, the Company consummated a
private placement of an additional $125 million of 91/8% senior notes due 2013. The additional 2013 Notes were
issued pursuant to the same Indenture at 101.125% of the face amount, for gross proceeds of approximately $140.6 million, before estimated offering expenses and the initial purchasers discount. The Company applied the net proceeds from
the sale of the additional 2013 Notes to repay indebtedness outstanding under its revolving credit facility.

Repayment of the Second Lien Term
Loan Facility

On July 12, 2006, in connection with its entry into the revolving credit facility and the closing of its sale of the
2013 Notes, the Company repaid all amounts outstanding under, and terminated, its Amended and Restated Second Lien Term Loan, dated as of July 28, 2005, between the Company, each of the Lenders from time to time party thereto and BNP Paribas,
as administrative agent for the Lenders.

97/8% Senior Notes

On April 8, 2004, Mission issued $130.0 million of its 97/8% senior notes due 2011 (the 2011 Notes). The Company assumed these notes upon the closing of the Mission merger. In conjunction with the KCS merger, the Company extinguished
substantially all of its 2011 Notes for a premium of $14.9 million plus accrued interest of $3.5 million. There were approximately $0.3 million of the notes which were not redeemed and are still outstanding as of September 30, 2006.

Debt Issuance Costs

The
Company capitalizes certain direct costs associated with the issuance of long-term debt. At September 30, 2006, the Company has approximately $15.6 million of net debt issuance costs being amortized over the lives of the respective debt. Debt
issuance costs increased $13.6 million from December 31, 2005 primarily due to the issuance of additional debt in the third quarter of 2006.

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.

6. COMMITMENTS AND CONTINGENCIES

The Company is a defendant in various legal proceedings arising in the normal course of
business. 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 for 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 Companys operating results, financial position or cash flows.

In connection with the KCS
merger of the Company and KCS, the Company assumed by operation of law all liabilities of KCS, including the 2012 Notes, which were originally issued by KCS in April 2004. U.S. Bank National Association served as Trustee under the indenture
governing the 2012 Indenture from and after the date of issuance until October 13, 2006 when the Company believes it resigned. The Company intends to exercise its rights under the 2012 Indenture to appoint a successor trustee.

Prior to the merger, the Company carefully considered the Change of Control provisions of the 2012 Indenture and, at the consummation of the merger, the
Company concluded that the transaction did not trigger a Change of Control based upon the facts and the specific language of the 2012 Indenture. Consequently, the Company did not make a Change of Control Offer within 30 days of the merger.

On September 15, 2006, The Law Debenture Company of New York filed suit in the Court of Chancery of the State of Delaware, New Castle
County, against the Company, its board of directors, certain of its officers, KCS and certain former members of the board of directors and past management of KCS, based on the assertion that a Change of Control occurred as a consequence of the
Companys merger with KCS. On October 9, 2006, the Company received a letter from Law Debenture alleging default on the basis of the Companys failure to make a Change of Control Offer. The Company does not believe that Law Debenture
has been validly appointed Trustee and, therefore, believes that any action purportedly taken by Law Debenture in such capacity is invalid and without effect. In addition, the Company has never received a valid Notice of Default, as required by the
2012 Indenture. The Company intends to vigorously defend itself against these claims and to aggressively pursue all legal remedies available to it.

On October 2, 2006, the Company deposited a regular semi-annual interest payment on the 2012 Notes with its paying agent, The Bank of New York Trust Company, N.A., to be held in trust for payment on the 2012 Notes. In disregard of that
trust, without any notice to the Company, and lacking authorization or entitlement of

any kind, Law Debenture instructed the Companys paying agent to deduct $1.2 million from that deposit for the use of Law Debenture for its own fees,
costs and expenses. This action effectively reduced interest payments to all holders by $1.2 million.

The Company believes that Law
Debentures actions are unlawful, and has filed an action in the United States District Court for the Southern District of New York asserting claims for conversion and tortious interference and asking the court to impose a constructive trust in
favor of the Company. The Company seeks relief including the return of monies diverted by Law Debenture, an award of restitution and damages (including punitive damages) and such other relief as the court deems just, equitable and proper.

Prior to the acquisition of Mission Resources Corporation by the Company, 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 September 30, 2006, there have
been no payments made, or liabilities recorded, as a result of these agreements.

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 September 30, 2006, the Company had 73 open positions summarized in the table below: 30 natural gas price collar arrangements, 11
natural gas price swap arrangements, five natural gas put options, six crude oil price swap arrangements and 21 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 September 30, 2006, the Company had a $56.0 million derivative asset, $44.6 million of which is classified as current, and a $28.7 million derivative liability, $13.6 million of which is classified as current. The weighted average
of the forward strip prices used to value the derivative liability were $67.42 per barrel of oil (Bbl) and $7.47 per million British thermal unit (Mmbtu) of natural gas.

The Company recorded a net derivative gain of $68.0 million ($0.7 million cash paid on settled contracts) and $94.5 million ($11.8 million cash paid on settled contracts) for the three and nine months ended
September 30, 2006, respectively.

At September 30, 2005, the Company had 65 open positions: 33 natural gas price collar
arrangements, one natural gas price swap arrangement, one crude oil price swap arrangement and 30 crude oil collar arrangements. The Company had a $132.7 million derivative liability, $86.4 million of which was classified as current.

The Company recorded a net derivative loss of $83.6 million and $120.6 million for the three and nine months ended September 30, 2005, respectively.

8. STOCKHOLDERS EQUITY

In conjunction with the KCS merger on July 12, 2006, the Company issued approximately 83.8 million shares of its common stock as consideration to the former shareholders of KCS.

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
(as defined below) 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. These 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 outside the United States within the meaning of Regulation S under the Act. The placement agents for this offering received a cash payment of approximately $7.7 million as compensation
for services provided in connection with the offering and to reimburse them for certain expenses.

These shares were registered for resale
on March 20, 2006 in conjunction with the filing of a Registration Statement on Form S-3 (No. 33-132565) in accordance with the terms of a registration rights agreement entered into by the Company.

The Company registered 19.565 million shares of common stock that were issued as merger consideration to holders of Mission stock.

8% Cumulative Preferred Stock

In June 2001, the
Company completed a Private Placement offering of 8% cumulative convertible preferred stock and common stock purchase warrants, offered as units of one preferred share and one-half of one warrant at $9.25 per unit. In the offering, the Company
issued 604,271 preferred shares and 151,070 warrants to purchase a like number of shares of the Companys common stock. In April 2006, the Company initiated a buyback of the preferred stock for $9.25 per unit. On June 9, 2006, the Company
sent the holders of the preferred shares notice of redemption as set forth in the certificate of designation for the preferred stock. On July 10, 2006, the Company completed the redemption of the preferred stock. As of September 30, 2006,
there were no remaining preferred shares outstanding. All Class A and Class B warrants associated with the preferred stock expired on June 29, 2006.

Stock Option Grants

During the first nine months of 2006, the Company granted stock options covering 1,866,270 shares of
common stock to employees of the Company. The options have exercise prices ranging from $9.80 to $16.04 with a weighted average price of $11.93. These options vest over a three year period at a rate of one-third on the annual anniversary date of the
grant and expire ten years from the grant date.

shares of common stock to employees of the Company. The options vest over a two-year period with one-third vesting on the date of grant, one-third one year from the date of the grant and the remaining one-third two years from the date of the grant.

In connection with the KCS merger, the Company converted legacy KCS stock options into a total of
2,585,950 Petrohawk stock options on July 12, 2006. These options vest over a three-year period and expire ten years after the date of grant. Weighted average grant date fair value of the options was determined to be $9.81 per share, using the
Black-Scholes fair value method. The Company recognized $0.4 million in compensation cost for the quarter ended September 30, 2006 and will recognize $1.7 million in future periods related to these options.

Restricted Stock

During the first nine months of
2006, the Company granted 887,638 shares of restricted common stock to employees and non-employee directors of the Company. These restricted shares were granted at prices ranging from $9.80 to $16.04 with a weighted average price of $11.71. Employee
shares vest over a three-year period at a rate of one-third on the annual anniversary date of the grant and the directors shares cliff vest after a six-month period.

In connection with the KCS merger, the Company converted legacy KCS restricted stock into 616,238 shares of Petrohawk restricted stock on July 12,
2006. These shares cliff vest after a three-year period and expire ten years after the date of grant. These shares were valued at the closing price on the date of the KCS merger of $12.36. The Company recognized $0.5 million in compensation cost for
the quarter ended September 30, 2006 and will recognize $3.8 million in future periods related to these shares.

Employee shares vest over a three-year period at a rate of one-third on the annual anniversary date of the grant and the directors shares cliff vest after a six-month period.

Performance Shares

In conjunction with the KCS merger, the Company adopted a plan under which
performance share awards are granted under the KCS 2005 Stock Plan. Performance awards contain a contingent right to receive shares of common stock. The grantee would earn between 0% and 200% of the target amount of performance shares upon the
achievement of pre-determined objectives over a three-year performance period. The objectives relate to the Companys total stockholder return (as defined in the form of performance share agreement) as compared to the total stockholder return
of a group of peer companies during the performance period. The Company does not anticipate the issuance of any additional performance share awards in future periods. No performance shares have yet been earned.

The fair value of this award using a Monte Carlo technique was $10.89 per share. The Company will recognize compensation cost of $1.5 million over the
expected service life of this performance share award whether or not the threshold is achieved. The Company recognized $0.1 million in compensation cost for the period between the KCS merger and September 30, 2006.

Treasury Stock

In August 2004, the
Companys Board of Directors terminated the stock repurchase program. During the quarter ended September 30, 2006, the Company retired its 8,382 treasury shares.

12. SUBSEQUENT EVENTS

The Company has entered into two separate definitive agreements with two different buyers to sell certain of its oil and gas assets in Wyoming and Michigan. All of these assets were acquired by the Company as a result
of the KCS merger. The total purchase price for both transactions is approximately $90 million, before adjustments. The Company expects both transactions to close during the fourth quarter of 2006. Upon closing, proceeds from sale will be recorded
as a decrease to the Companys full cost pool.

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

The
following review of operations for the three and nine months ended September 30, 2006 and 2005 should be read in conjunction with our Consolidated Financial Statements and the Notes thereto included in this Form 10-Q and with the Consolidated
Financial Statements, Notes and Managements Discussion and Analysis included in our 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 East Texas/North Louisiana, Gulf Coast, Permian Basin, and Anadarko/Arkoma regions. 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. We have increased our
proved reserves and production principally through acquisitions in conjunction with an active drilling program. Our acquisition activities 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 nine months of 2006, we produced 50.6 billion cubic
feet of natural gas equivalent (Bcfe) compared to production of 19.0 Bcfe for the comparable period of the prior year. Natural gas production was 38.9 billion cubic feet (Bcf) and oil production was 1,962 thousand barrels of oil (Mbbls) for the
first nine months of 2006. Natural gas equivalent production increased 31.6 Bcfe from the same period in 2005. This increase was primarily attributable to the completion of our merger with KCS in July 2006 as well as the acquisition of Mission in
July of 2005, the North Louisiana Acquisitions in January of 2006 as well as our continued drilling success. We drilled 235 wells during the first nine months of 2006 (105 during the third quarter), 227 of which were successful (103 for the third
quarter) for a success rate of 97% (98% for the third quarter). We reported oil and gas revenues for the nine months ended September 30, 2006 of $385.9 million. This represents an increase of $235.9 million as compared to the prior year. The
increase in our production and oil and natural gas revenues was principally through acquisitions complemented by our continued drilling success.

Our financial results depend upon many factors, particularly commodity prices 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. Our risk management policy provides for the use of derivative instruments to manage these risks. The types of derivative instruments that we may utilize include futures, swaps, options and
fixed price physical delivery contracts. The volume of derivative instruments we utilize is governed by the risk management policy and can vary from year to year.

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. During the first nine months of
2006, our average price realized for equivalent gas production decreased approximately $0.26 per thousand cubic feet of natural gas equivalent (Mcfe), or 3.3%, to $7.62 compared to the $7.88 per Mcfe realized in the prior year. The change in the
average price realized primarily reflects changes in average spot market prices. Historically, commodity prices have been volatile and we expect them to remain volatile.

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

Capital Resources and Liquidity

For the first nine
months of 2006, we funded our capital program exclusive of acquisitions primarily with cash flows from operations. The North Louisiana Acquisitions in January 2006 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
indebtedness under our debt facilities. 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.
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 decrease in cash is summarized as follows:

Operating Activities. Net cash provided by operating activities for the nine months ended
September 30, 2006 and 2005 were $182.3 million and $85.4 million, respectively. Key drivers of net operating cash flows are commodity prices, production volumes and operating costs. Average natural gas prices decreased 9.5% over 2005, while
crude oil prices increased 19.3% over the same period. Production volumes increased significantly with a 167% increase in equivalent production in 2006 compared to 2005 primarily due to the acquisition of KCS in July 2006, Mission in July 2005 and
the completion of the North Louisiana Acquisitions in January 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 was $925.6 million and $149.8 million for the nine months ended September 30, 2006 and 2005, respectively.

On April 21, 2006, we announced that we entered into definitive agreement to merge with KCS. This transaction was consummated on
July 12, 2006 and was consistent with our goals of acquiring properties within our core operating areas that have a significant proved reserve component and which we believe have additional development and exploration opportunities. Total
consideration for the shares of KCS common stock was comprised of approximately $1.1 billion of our common stock, approximately $450 million of cash and the assumption of $275 million of KCS debt. In addition, all outstanding options to purchase KCS
common stock were converted into options to purchase our common stock.

During the first quarter of 2006, we completed the acquisition of
Winwell for $208 million in cash after closing adjustments, as well as the acquisition of certain oil and gas properties for $86 million in cash after closing adjustments. In conjunction with these acquisitions, we deposited a total of $22.5 million
in earnest money that was included in other non-current assets at December 31, 2005 and applied to the overall purchase price in January of 2006.

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 debt facilities. We received an additional $12.6 million in proceeds from the sale of assets during the third quarter of 2006 primarily related to the sale of a group of non-operated properties.

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.

##### Table of Contents

Our capital budget for the remainder of 2006 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.

Financing Activities. Net cash flows provided by financing activities were $736.6 million for the nine months ended September 30, 2006. Cash
flows provided by financing activities in 2006 were the result of increased borrowings, primarily to fund acquisitions.

the North Louisiana Acquisitions, on February 1, 2006, we issued and sold 13 million shares of our common stock for $14.50 per share, for an aggregate offering amount of approximately $188.5 million. Contemporaneously with the offering, we
repurchased approximately 3.3 million shares of common stock, $46.2 million from EnCap Investments, L.P. and certain of its affiliates. We incurred a total of $10.7 million of offering costs during the nine months ended September 30, 2006.

We strive to maintain excess availability under our debt facilities. Excess cash flow and non-core asset sales are used to repay debt to
the extent available. During the first nine months of 2006, we had net borrowings of $637.9 million primarily due to the funding requirements to close the KCS merger and the North Louisiana Acquisitions.

Financing activities in 2006 included $14.6 million of cash paid on settled derivative contracts that were acquired in conjunction with our acquisition
activities.

During the first nine months of 2006, we paid our previously accrued fourth quarter of 2005 dividends of $0.1 million on our
8% cumulative convertible preferred stock as well as our first and second quarter 2006 dividends of $0.1 million each. In April 2006, we initiated a buyback of this preferred stock for $9.25 per unit, resulting in a $4.4 million use of cash from
financing activities.

Net cash flows provided by financing activities were $62.9 million for the nine months ended September 30, 2005
primarily due to our net borrowings of $61 million. Financing activities in 2005 included $9.7 million of cash paid on settled derivative contracts that were acquired in conjunction with our acquisition activity. During the first nine months of
2005, we paid the first and second quarter dividends of $0.1 million each and accrued the third quarter dividend of $0.1 million as it was not paid until the fourth quarter of 2005.

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.

On July 12, 2006, we completed our previously
announced merger with KCS. Please refer to Note 2, Acquisitions and Divestitures, for more details on the KCS merger and various related transactions that occurred in conjunction with the closing of the merger.

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 September 30, 2006 and 2005

We reported net income of $52.7 million for the three months ended
September 30, 2006 compared to a net loss of $36.4 million for the comparable period in 2005. The increase in net income of $89.1 million from prior year was primarily driven by an increase in sales volumes due to our acquisition activities, as
well as a $151.6 million net increase in our gain on derivative contracts primarily due to the recent decline in natural gas prices.

##### Table of Contents

For the three months ended September 30, 2006, oil and gas sales increased $115.0 million from the
comparable period in 2005, to $196.4 million. The increase for the three months is primarily attributable to an increase in production volumes from the closing of the KCS merger in July 2006 as well as the acquisition of Mission in July 2005
and the North Louisiana Acquisitions in January 2006. This increase in production was partially offset by a decrease in our realized natural gas equivalent price of $1.65, or 18.3%, which decreased revenues approximately $44.0 million.

Lease operating expenses increased $7.3 million for the three months ended September 30, 2006 as compared to the same period in 2005. This
increase is primarily due to the increase in overall production of 17.6 Bcfe as a result of our recent acquisition activities and our continued drilling success. On a per unit basis, lease operating expenses decreased $0.48 per Mcfe to $0.66 per
Mcfe as compared to $1.14 per Mcfe for the same period in 2005. The decrease on a per unit basis is primarily due to our continued cost control efforts to lower our lease operating expenses. We continue to identify divestment prospects which tend to
be outlying properties, properties that are not in our core focus areas, or those properties that are deemed to be higher cost, such as the offshore properties that we acquired from Mission in July 2005 and divested in 2006. Also contributing to the
decrease on a per unit basis was our acquisition of lower cost properties from KCS and properties we acquired in the North Louisiana Acquisitions.

Taxes other than income increased $9.3 million for the three months ended September 30, 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 decreased $0.12 per Mcfe to $0.59 per Mcfe in 2006 as compared to $0.71 per Mcfe during
the same period in 2005. As a percentage of oil and gas sales, taxes other than income were approximately eight percent for both periods.

General and administrative expenses for the three months ended September 30, 2006 increased $6.4 million to $12.1 million compared to the same period in 2005. This increase was primarily due to the acquisition of KCS in July of 2006
which increased compensation and other costs associated with increased staffing levels to meet the demands of our expanding operations. General and administrative expenses have decreased significantly on a per Mcfe basis from $0.64 per Mcfe for the
three months ended September 30, 2005 to $0.46 per Mcfe for the comparable period of 2006 as production increases have outpaced our administrative expenses. As previously discussed, we intend to concentrate our activities in our core operating
areas and exploit our multi-year drilling inventory. Operating in concentrated areas helps us to better control our overhead by enabling us to manage a greater amount of acreage with fewer employees and minimize incremental costs of increased
drilling and production. Our strategy of targeting our operations in relatively focused areas permits us to more efficiently capitalize on our base of geological, engineering and production experience in these regions.

Stock-based compensation increased $2.4 million for the three months ended September 30, 2006 as compared to the same period in 2005. This increase
is primarily related to additional stock options and restricted stock grants assumed as part of the acquisition of KCS in July of 2006, as well as the stock options and restricted stock grants given to employees and non-employee directors in the
third quarter of 2006.

Depletion expense increased $66.3 million, to $88.5 million for the three months ended September 30, 2006 as
compared to the same period in 2005. 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 $0.86 per Mcfe to $3.32 per Mcfe. This increase is primarily due to the acquisition of KCS in July of 2006, the
North Louisiana Acquisitions in January of 2006 and the acquisition of Mission in July of 2005, as well as an increase in our estimated future development costs which are a significant component of the depletion calculation.

We enter into derivative commodity instruments to hedge our exposure to price fluctuations on our anticipated oil and gas production. Consistent with the
prior year, 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 September 30, 2006, we had a net derivative asset of $27.3 million and recorded an unrealized net derivative gain of $68.0 million ($0.7 million cash paid on settled contracts) for the three months ended
September 30, 2006 compared to a net derivative loss of $83.6 million in the prior year. The increase in our net derivative gain over the prior year period is due to the decrease in commodity prices, primarily the decline in natural gas prices
in July.

Interest expense and other for the three months ended September 30, 2006 increased $25.9 million from the same period in
2005. This increase is primarily due to the additional debt we incurred in conjunction with the acquisition of KCS in July of 2006, the acquisition of Mission in July of 2005 and the closing of the North Louisiana Acquisitions in January of 2006, as
well as premiums paid to extinguish previously assumed Mission debt.

increased $53.3 million from the prior year. The increase in income tax expense from prior year is primarily due to our pre-tax income of $82.9 million in 2006 compared to a pre-tax net loss of $59.5 million in 2005. The effective tax rates for the
three months ended September 30, 2006 and 2005 were 36.5% and 38.8%, respectively. The decrease in our effective tax rate from the prior year is primarily due to changes in state apportionment percentages due to the merger of KCS properties
with historical Petrohawk properties. Offsetting this decrease was an increase in the Companys effective tax rate for the recognition of a change in the Texas state income tax rate due to a change in the tax law. In May 2006, the State of
Texas enacted substantial changes to its tax structure beginning in 2007 by imposing a new tax based upon modified gross revenue referred to as the Margin Tax. We determined the Margin Tax to be an income tax as defined
under Statement of Financial Accounting Standards No. 109,Accounting for Income Taxes.

Results of Operations

Nine Months Ended September 30, 2006 and 2005

We
reported net income of $90.5 million for the nine months ended September 30, 2006 compared to a net loss of $52.9 million for the comparable period in 2005. The increase in net income of $143.3 million from prior year was primarily driven by an
increase in sales volumes due to our acquisition activities, as well as a $215.1 million net increase in our gain on derivative contracts primarily due to the recent decline in natural gas prices.

##### Table of Contents

For the nine months ended September 30, 2006, oil and gas sales increased $235.9 million from the
comparable period in 2005, to $385.9 million. The increase for the nine months is primarily attributable to an increase in production volumes of 31.6 Bcfe from the closing of the KCS merger in July of 2006 as well as the acquisition of Mission
in July of 2005 and the North Louisiana Acquisitions in January of 2006. This increase in production was partially offset by a decrease in our realized natural gas equivalent price of $0.26, or 3.3%, which decreased revenues approximately $13
million.

Lease operating expenses increased $20.6 million for the nine months ended September 30, 2006 as compared to the same period
in 2005. This increase is primarily due to the increase in overall production of 31.6 Bcfe as a result of our recent acquisition activities and our continued drilling success. On a per unit basis, lease operating expenses decreased $0.24 per Mcfe to
$0.80 per Mcfe as compared to $1.04 per Mcfe for the same period in 2005. The decrease on a per unit basis is primarily due to our continued cost control efforts to lower our lease operating expenses. We continue to identify divestment prospects
which tend to be outlying properties, properties that are not in our core focus areas, or those properties that are deemed to be higher cost, such as the offshore properties that we acquired from Mission in July of 2005 and divested in 2006. Also
contributing to the decrease on a per unit basis was our acquisition of lower cost properties from KCS and properties we acquired in the North Louisiana Acquisitions.

Taxes other than income increased $19.5 million for the nine months ended September 30, 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 $0.03 per Mcfe to $0.60 per Mcfe in 2006 as compared
to $0.57 per Mcfe during the same period in 2005. As a percentage of oil and gas sales, taxes other than income were approximately eight percent and seven percent for the nine months ended September 30, 2006 and 2005, respectively.

General and administrative expenses for the nine months ended September 30, 2006 increased $12.6 million to $25.9 million compared to the same
period in 2005. This increase was primarily due to the acquisition of KCS in July of 2006 which increased compensation and other costs associated with increased staffing levels to meet the demands of our expanding operations. General and
administrative expenses have decreased significantly on a per Mcfe basis from $0.70 per Mcfe for the nine months ended September 30, 2005 to $0.51 per Mcfe for the comparable period of 2006 as production increases have outpaced our
administrative expenses. Operating in concentrated areas helps us to better control our overhead by enabling us to manage a greater amount of acreage with fewer employees and minimize incremental costs of increased drilling and production. Our
strategy of targeting our operations in relatively focused areas permits us to more efficiently capitalize on our base of geological, engineering and production experience in these regions.

Stock-based compensation increased $2.0 million for the nine months ended September 30, 2006 as compared to the same period in 2005. This increase
is primarily related to additional stock options and restricted stock grants assumed as part of the acquisition of KCS in July of 2006, as well as the stock options and restricted stock grants given to employees and non-employee directors during
2006.

Depletion expense increased $118.1 million to $162.2 million for the nine months ended September 30, 2006 as compared to the
same period in 2005. 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 $0.88 per Mcfe to $3.20 per Mcfe. This increase is primarily due to the acquisition of KCS in July of 2006, the North Louisiana
Acquisitions in January of 2006 and the acquisition of Mission in July of 2005, as well as an increase in our estimated future development costs which are a significant component of the depletion calculation.

##### Table of Contents

We enter into derivative commodity instruments to hedge our exposure to price fluctuations on our
anticipated oil and gas production. Consistent with the prior year, 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 September 30, 2006, we had a net derivative asset of $27.3 million and recorded
an unrealized net derivative gain of $94.5 million ($11.8 million cash paid on settled contracts) for the nine months ended September 30, 2006 compared to a net derivative loss of $120.6 million in the prior year. The increase in our net
derivative gain in the current year over the prior year is due to the decrease in commodity prices, primarily the decline in natural gas prices in July.

Interest expense and other for the nine months ended September 30, 2006 increased $35.6 million from the same period in 2005. This increase is primarily due to the additional debt we incurred in conjunction with
the acquisition of KCS in July of 2006, the acquisition of Mission in July of 2005 and the closing of the North Louisiana Acquisitions in January of 2006, as well as premiums paid to extinguish previously assumed Mission debt.

Income tax expense for the nine months ended September 30, 2006 increased $87.2 million from the prior year. The increase from prior year is
primarily due to our pre-tax income of $144.1 million in 2006 compared to a pre-tax net loss of $86.4 million in 2005. The effective tax rates for the nine months ended September 30, 2006 and 2005 were 37.2% and 38.8%, respectively. The
decrease in our effective tax rate from prior year is primarily due to changes in state apportionment percentages due to the merger of KCS properties with historical Petrohawk properties. Offsetting this decrease was an increase in the
Companys effective tax rate for the recognition of a change in the Texas state income tax rate due to a change in the tax law.

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 Disclosures about Market Risk

We are exposed to various risks
including energy commodity price risk. Management expects energy prices to remain volatile and unpredictable. If energy prices were to decline significantly, revenues and cash flow would significantly decline, and our ability to borrow to finance
our operations could be adversely impacted. In addition, a noncash writedown of our oil and gas properties could be required under full cost accounting rules if prices were to decline significantly. 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 risk management policy provides for the use of derivative instruments to manage these risks. The types of derivative instruments that we utilize include
futures, swaps, options and fixed price physical delivery contracts. The volume of derivative instruments that we may utilize is governed by the risk management policy and can vary from year to year, but under most circumstances will 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 additional information.

We are also exposed to market risk related to adverse changes in interest rates. Our interest rate risk exposure results primarily from fluctuations
in short-term rates, which are LIBOR and ABR based and may result in reductions of earnings or cash flows due to increases in the interest rates we pay on these obligations.

At September 30, 2006, total debt was $1.4 billion, of which approximately 74.3%, or $1.0 billion, bears interest at a weighted average fixed
interest rate of 8.6% per year. The remaining 25.7% of our total debt balance at September 30, 2006, or $363.0 million, bears interest at floating or market interest rates that at our option are

tied to prime rate or LIBOR. Fluctuations in market interest rates will cause our annual interest costs to fluctuate. At September 30, 2006, the
interest rate on our variable rate debt was 6.6% per year. If the balance of our bank debt at September 30, 2006 were to remain constant, a 10% change in market interest rates would impact our cash flow by approximately $0.6 million per
quarter.

Item 4. Controls and Procedures

As of the end of the 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 (as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended) 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.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

In connection with the KCS merger, the Company assumed by operation of law all
liabilities of KCS, including the 2012 Notes, which were originally issued by KCS in April 2004. U.S. Bank National Association served as Trustee under the indenture governing the 2012 Indenture from and after the date of issuance until
October 13, 2006 when the Company believes it resigned. The Company intends to exercise its rights under the 2012 Indenture to appoint a successor trustee.

Prior to the merger, the Company carefully considered the Change of Control provisions of the 2012 Indenture and, at the consummation of the merger, the Company concluded that the transaction did not trigger a Change
of Control based upon the facts and the specific language of the 2012 Indenture. Consequently, the Company did not make a Change of Control Offer within 30 days of the merger.

On September 15, 2006, The Law Debenture Company of New York filed suit in the Court of Chancery of the State of Delaware, New Castle County,
against the Company, its board of directors, certain of its officers, KCS and certain former members of the board of directors and past management of KCS, based on the assertion that a Change of Control occurred as a consequence of the
Companys merger with KCS and requesting, among other things, that the Company offer to repurchase the 2012 Notes at 101% face value. On October 9, 2006, the Company received a letter from Law Debenture alleging default on the basis of the
Companys failure to make a Change of Control Offer. The Company does not believe that Law Debenture has been validly appointed Trustee and, therefore, believes that any action purportedly taken by Law Debenture in such capacity is invalid and
without effect. In addition, the Company has never received a valid Notice of Default, as required by the 2012 Indenture. The Company intends to vigorously defend itself against these claims and to aggressively pursue all legal remedies available to
it.

On October 2, 2006, the Company deposited a regular semi-annual interest payment on the 2012 Notes with its paying agent, The
Bank of New York Trust Company, N.A., to be held in trust for payment on the 2012 Notes. In disregard of that trust, without any notice to the Company, and lacking authorization or entitlement of any kind, Law Debenture instructed the Companys
paying agent to deduct $1.2 million from that deposit for the use of Law Debenture for its own fees, costs and expenses. This action effectively reduced interest payments to all holders by $1.2 million.

##### Table of Contents

The Company believes that Law Debentures actions are unlawful, and has filed an action in the
United States District Court for the Southern District of New York asserting claims for conversion and tortious interference and asking the court to impose a constructive trust in favor of the Company. The Company seeks relief including the return
of monies diverted by Law Debenture, an award of restitution and damages (including punitive damages) and such other relief as the court deems just, equitable and proper.

Item 1A. Risk Factors

The following revised risk factors amend and supplement the Companys risk
factors as disclosed in Item 1A of Part I of the Companys 2005 Form 10-K:

We may not be able to successfully integrate the
businesses of Petrohawk and KCS following the KCS merger.

The success of the KCS merger depends in large part upon our ability to
integrate our organizations, operations, systems and personnel. The integration of two previously independent companies is a challenging, time-consuming and costly process. We have grown rapidly through recent acquisitions and will be required to
integrate our recent acquisitions with KCS. It is possible that the integration process could result in the loss of key employees, the disruption of each companys ongoing businesses or inconsistencies in standards, controls, procedures and
policies that adversely affect our ability to maintain relationships with suppliers, customers and employees or to achieve the anticipated benefits of the KCS merger. In addition, successful integration of the companies will require the dedication
of significant management resources, which will temporarily detract attention from the day-to-day businesses of the combined company. It we are not able to integrate our organizations, operations, systems and personnel in a timely and efficient
manner, the anticipated benefits of the KCS merger may not be realized fully or at all or may take longer to realize than expected.

We
may be required to take non-cash asset writedowns if natural gas and oil prices decline.

We may be required under full cost accounting
rules to write down the carrying value of natural gas and oil properties if natural gas and oil prices decline or if there are substantial downward adjustments to our estimated proved reserves, increases in our estimates of development costs or
deterioration in our exploration results.

We utilize the full cost method of accounting for natural gas and oil exploration and
development activities. Under full cost accounting, we are required by SEC regulations to perform a ceiling test each quarter. The ceiling test is an impairment test and generally establishes a maximum, or ceiling, of the book value of
natural gas and oil properties that is equal to the expected after tax present value (discounted at 10%) of the future net cash flows from proved reserves, including the effect of cash flow hedges, calculated using prevailing natural gas and oil
prices on the last day of the period or a subsequent higher price under certain limited circumstances. If the net book value of natural gas and oil properties (reduced by any related net deferred income tax liability and asset retirement obligation)
exceeds the ceiling limitation, SEC regulations require us to impair or writedown the book value of our natural gas and oil properties. Depending on the magnitude, a ceiling test writedown could significantly reduce income, or produce a
loss. As ceiling test computations involve the prevailing natural gas and oil prices, as of a fixed date, it is impossible to predict the likelihood, timing and magnitude of any future impairments. The book value of our proved natural gas and oil
properties increased in 2005 and during 2006 as a function of higher acquisition, exploration and development costs and the increase in future development costs associated with additional reserves. To the extent finding and development costs
continue to increase, we will become more susceptible to ceiling test writedowns in lower price environments.

Our results of operations could be adversely affected as a result of non-cash goodwill impairments.

In conjunction the recording of the KCS purchase price allocation, we recorded goodwill which represents the excess of the purchase
price paid by us for KCS plus liabilities assumed, including deferred taxes recorded in connection with the KCS merger, over the estimated fair market value of the tangible net assets acquired.

Goodwill is not amortized, but instead must be tested at least annually for impairment by applying a fair value based test. Goodwill is deemed impaired
to the extent of any excess of its carrying amount over the residual fair value of the business. Such non-cash impairment could significantly reduce earnings during the period in which the impairment occurs, and would result in a corresponding
reduction to goodwill and stockholders equity.
