1. Summary of Significant Accounting Policies

The accounting policies followed by Gastar Exploration Ltd. (the Company) are set forth in the notes to the Companys audited condensed
consolidated financial statements in its Annual Report on Form 10-K for the year ended December 31, 2007. Additionally, refer to the notes to those financial statements for additional details of the Companys financial condition, results
of operations and cash flows. All material items included in those notes have not changed except as a result of normal transactions in the interim or as disclosed within this report. The accompanying interim condensed consolidated financial
statements have not been audited by independent registered public accountants but, in the opinion of management, reflect all normal and recurring adjustments considered necessary for a fair presentation of the financial position and results of
operations. The results of operations for the three and six months ended June 30, 2008 are not necessarily indicative of results to be expected for the full year.

The condensed consolidated financial statements of the Company are presented in United States dollars unless otherwise noted and have been prepared by management in accordance with US GAAP. The preparation of
financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates with regard to these financial statements include the estimate of proved natural gas
and oil reserve quantities and the related present value of estimated future net cash flows.

The condensed consolidated financial
statements include the accounts of the Company and the consolidated accounts of all its subsidiaries. The entities included in these consolidated accounts are all wholly owned. All significant intercompany accounts and transactions have been
eliminated in consolidation.

Certain information provided for the prior period has been reclassified to conform to the presentation
adopted in 2008.

New Accounting Pronouncements

Disclosures about Derivative Instruments and Hedging Activities. In March 2008, the Financial Accounting Standards Board (FASB) issued Statements of Financial Accounting Standards (SFAS)
SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities (SFAS No. 161). SFAS No. 161 does not change accounting policy for derivatives but requires enhanced disclosures about how and why
an entity uses derivative instruments, how derivative instruments and related hedged items (if any) are accounted for, and how they affect the Companys financial position, financial performance and cash flows. SFAS No. 161 is effective
for annual and interim periods beginning with the first quarter of 2009. The Company is evaluating the provisions of SFAS No. 161.

Non-controlling Interests in Consolidated Financial Statements. In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statements, an amendment of Accounting Research Bulletin
No. 51 (SFAS No. 160), which improves the relevance, comparability and transparency of the financial information that a reporting entity provides in its consolidated financial statements by establishing accounting and
reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. This statement is effective for fiscal years beginning after December 15, 2008. The Company does not expect the adoption of SFAS
No. 160 to have a material impact on the Companys consolidated financial position, results of operations or cash flows.

Business Combinations.In December 2007, FASB issued SFAS No. 141 (revised 2007), Business Combinations (SFAS No. 141R), which replaces SFAS No. 141, Business Combinations
(SFAS No. 141). SFAS 141R retains the fundamental requirements in SFAS No. 141 that the acquisition method of accounting (which SFAS No. 141 called the purchase method) be used for all business combinations. SFAS
No. 141R also establishes principles and requirements for how the acquirer: (a) recognizes and

measures in its financial statements the identifiable assets acquired, the liabilities assumed, and any noncontrolling interest in the acquiree;
(b) recognizes and measures the goodwill acquired in the business combination or a gain from a bargain purchase; and (c) determines what information to disclose to enable users of the financial statements to evaluate the nature and
financial effects of the business combination. SFAS No. 141R is effective as of the beginning of an entitys fiscal year that begins after December 15, 2008. Early adoption is prohibited. The Company is currently evaluating the impact
of adopting SFAS No. 141R, which also requires acquisition transaction costs to be expensed as incurred rather than capitalized as a direct cost of the acquisition, as transaction costs are not considered an element of the fair value of the
company acquired. Depending upon the size, nature and complexity of a future acquisition transaction, such transaction costs could be material to the Companys results of operations.

Accounting Standard Fair Value for Financial Assets and Financial Liabilities.In February 2007, the FASB issued SFAS No. 159, The Fair
Value Option for Financial Assets and Financial Liabilities (SFAS No. 159). SFAS No. 159 allows entities the option to measure eligible financial instruments at fair value as of specified dates. Such election,
which may be applied on an instrument-by-instrument basis, is typically irrevocable once elected. SFAS No. 159 is effective for fiscal years beginning after November 15, 2007, and early application is allowed under certain
circumstances. The Company adopted SFAS No. 159 on January 1, 2008, which allows an entity the irrevocable option to elect fair value for the initial and subsequent measurement for certain financial assets and liabilities on a
contract-by-contract basis. The Company did not elect fair value as an alternative, as provided under SFAS No. 159 for any of its financial assets and liabilities that are not currently measured at fair value.

Fair Value Measurements.In September 2006, the FASB issued SFAS 157, Fair Value Measurements (SFAS No. 157), which
defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. SFAS No. 157 applies to other accounting pronouncements that require or permit fair value measurements; however, it
does not require any new fair value measurements. The provisions of SFAS No. 157 are effective for the years beginning after November 15, 2007 and interim periods within those years. The FASB has also issued Staff Position FSP FAS
No. 157-2 (FSP FAS No. 157-2), which delays the effective date of SFAS No. 157 for nonfinancial assets and liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a
recurring basis (at least annually), until fiscal years beginning after November 15, 2008. Effective January 1, 2008, the Company adopted SFAS No. 157 and has chosen to defer the implementation of nonfinancial assets and liabilities
in accordance with FSP FAS No. 157-2. The effect of adoption in January 1, 2008 was immaterial to the Companys financial position. The adoption of FSP FAS No. 157-2 is not expected to have a material impact on the Companys
results of operations, cash flows or financial positions. See Note 10 for additional information regarding the adoption of SFAS No. 157.

At June 30, 2008, unproved properties not being amortized consisted of United States drilling
in progress costs of $2.5 million, United States acreage acquisition costs of $91.0 million and Australian unevaluated property costs of $17.3 million.

There was no impairment of United States or Australian properties during the six months ended June 30, 2008. For the six months ended June 30, 2007, the results of managements ceiling test evaluation
resulted in an impairment of United States proved properties of $28.5 million. Management determined that no impairment was required on Australian properties during six months ended June 30, 2007.

purposes. Interest is payable semi-annually in arrears on June 1 and December 1, in cash on the principal amount at an annual rate of 123/4%. The annual effective interest rate, after amortization of the debt discount and fees paid to establish the 123/4% Senior Secured Notes, is 14.85%. The 123/4% Senior Secured Notes are fully and unconditionally guaranteed jointly and severally by Gastar USA, the Parent and all of the Parents existing and future material domestic subsidiaries.
The 123/4% Senior Secured Notes and the guarantees are secured by a lien on Gastar USAs principal domestic natural gas and
oil properties and other assets that secure Gastar USAs revolving credit facility (Revolving Credit Facility), subject to certain exceptions. The 123/4% Senior Secured Notes mature on December 1, 2012.

As of June 30, 2008, the Company was in compliance with all debt covenants under the 123/4% Senior Secured Notes.

Revolving Credit Facility

On November 29, 2007,
concurrent with the closing of the 123/4% Senior Secured Notes, Gastar USA entered into a Revolving Credit Facility providing
for a first priority lien borrowing base. The borrowing base is to be redetermined at least semi-annually, using the lenders usual and customary criteria for natural gas and oil reserve valuation. The administrative agent to the Companys
Revolving Credit Facility has recently approved, subject to the agreement of the other syndication banks, to increase our borrowing base to $45.0 million, of which $6.5 million is being utilized as collateral for a letter of credit to support the
Companys hedging activities. The applicable interest rate margin varies from -0.75% to 0.0% in the case of borrowings based on the prime rate and from 1.5% to 2.25% in the case of borrowings based on the Eurodollar rate, depending on the
utilization level in relation to the borrowing base. At June 30, 2008, the prime rate and the Eurodollar rate were 5.0% and 2.5%, respectively. The Revolving Credit Facility is guaranteed by the Parent and all its current domestic subsidiaries
and all future domestic subsidiaries formed during the term of the Revolving Credit Facility. Borrowings and related guarantees under the Revolving Credit Facility are secured by a first priority lien on all domestic natural gas and oil properties
currently owned by or later acquired by Gastar USA, excluding de minimus value properties as determined by the lender. The Revolving Credit Facility matures on October 15, 2009.

As of June 30, 2008, the Company was in compliance with all debt covenants under the Revolving Credit Facility.

Convertible Senior Unsecured Debentures

In
November 2004, the Company issued $30.0 million aggregate principal amount of convertible senior unsecured debentures. The convertible senior unsecured debentures have a term of five years and are due November 20, 2009 and bear interest at
9.75% per annum, payable quarterly. The convertible senior unsecured debentures are convertible by the holders into 6,849,315 common shares at a conversion price of $4.38 per share.

Subordinated Unsecured Notes Payable

The Companys subordinated unsecured notes mature
between April 2009 and September 2009, bear interest at 10% per annum and are callable by the Company at 101%. As of June 30, 2008, $2.9 million of the subordinated unsecured notes was reflected as current portion of long-term debt.

4. Equity Compensation Plans

Share-Based
Compensation Plans

2002 Stock Option Plan. The Companys 2002 Stock Option Plan was approved and ratified by the
Companys shareholders in July 2002. It authorizes the Companys Board of Directors to issue stock options to directors, officers, employees and consultants of the Company and its subsidiaries to purchase a maximum of 25.0 million
common shares. Stock option grant expirations vary between five and 10 years.

The vesting schedule has varied from two years to four years but generally has occurred over a four-year period at 25% per year beginning on the first
anniversary date of the grant. Stock options issued pursuant to the Companys 2002 Stock Option Plan have an exercise price determined by the Board of Directors, but that exercise price cannot be less than the market price on the date
immediately prior to the date of grant as reported by any stock exchange on which the Companys common shares are listed. If a stock option granted under the Companys 2002 Stock Option Plan expires or terminates for any reason in
accordance with the terms of the 2002 Stock Option Plan, the unpurchased common shares subject to that stock option become available for other stock option grants.

In April 2004, the Board of Directors amended the provisions of the 2002 Stock Option Plan to specifically incorporate a provision to provide for stock options to be exercised on a cashless basis, whereby the Company
issues to the optionee the number of common shares equal to the stock option exercised, less the number of common shares which when multiplied by the market price at the date of exercise equals the aggregate exercise price for all of the common
shares exercised.

As of June 30, 2008, stock option grants covering the issuance of 9,648,750 common shares were outstanding under
the 2002 Stock Option Plan.

2006 Gastar Long-Term Stock Incentive Plan.On June 1, 2006, the Companys shareholders
approved the 2006 Gastar Long-Term Stock Incentive Plan. The 2006 Gastar Long-Term Stock Incentive Plan authorizes the Companys Board of Directors to issue stock options, stock appreciation rights, bonus stock awards and any other type of
award established by the Remuneration Committee, which is consistent with the Plans purposes, to directors, officers and employees of the Company and its subsidiaries covering a maximum of 5.0 million common shares. The contractual life
and vesting period for a grant is determined by the Board of Directors at the time the grant is awarded. The vesting period for restricted common stock grants during 2007 and 2008 was over four years, with one-third vesting on the second, third and
fourth anniversaries of the date of grant. As of June 30, 2008, grants covering the issuance of 2,796,343 restricted common shares were outstanding under the 2006 Gastar Long-Term Stock Incentive Plan.

Determining Fair Value under SFAS No. 123R

In determining fair value for stock option grants pursuant to SFAS 123R, Share-Based Payments (SFAS No. 123R), the Company utilized the following assumptions:

Valuation and Amortization Method. The Company estimates the fair value of share-based awards granted using the Black-Scholes-Merton valuation
model. The fair value of all awards is expensed using the graded-vesting method.

Expected Life.The expected life of
awards granted represents the period of time that stock options are expected to be outstanding. Prior to 2008, the Company determined the expected life using the simplified method resulting in a 6.25-year expected life in accordance with
Staff Accounting Bulletin No. 107 for all stock options issued with a four-year vesting period and a ten-year grant expiration. Using the simplified method, stock options that have been issued with two and three-year vesting periods and having
a ten-year expiration have an expected life of 5.75 and 6.0 years, respectively. Beginning in 2008, management determined the expected life of stock option grants to be 6.25 years, based on historical records.

Expected Volatility. Using the Black-Scholes-Merton valuation model, the Company estimates the volatility of its common shares at the beginning of
the quarter in which the stock option is granted. The volatility is based on historical movements of our common share price on the American Stock Exchange and the Toronto Stock Exchange over a period that approximates the expected life.

Risk-Free Interest Rate. The Company utilizes a risk-free interest rate equal to the rate of
United States Treasury zero-coupon issues as of the date of grant with a term equivalent to the stock options expected life.

Expected Dividend Yield. The Company has not paid any cash dividends on its common shares and does not anticipate paying any cash dividends in the foreseeable future. Consequently, a dividend yield of zero is utilized in the
Black-Scholes-Merton valuation model.

Expected Forfeitures. Beginning March 1, 2008, the Company increased the forfeiture rate
to 6% from 5%. The forfeiture rate is used in calculating compensation expense and is based on the number of forfeitures of all unvested stock option since January 1, 2004 as a percentage of all stock option grants since January 1, 2004
calculated at the beginning of the year.

The fair value of each stock option grant is estimated on the date of grant using the
Black-Scholes-Merton valuation pricing model. There were no stock options granted during the six months ended June 30, 2008. The table below summarizes the number of stock options granted and the assumptions for the stock options granted for
the six months ended June 30, 2007.



|                        |  |                                      |

The weighted average grant date fair value of stock options granted and the intrinsic value of
stock options exercised are shown below for the periods indicated. Intrinsic value of stock options is calculated using the difference between the common share price on the date of exercise and the exercise price times the number of stock options
exercised. There were no stock options granted or exercised during the six months ended June 30, 2008. The table below sets forth the weighted average fair value per share of stock options granted and the intrinsic value of stock options
exercised during the six months ended June 30, 2007.

As
of June 30, 2008, the Companys current cash flow hedge positions were with counterparties that are major United States financial institutions. The credit support for certain of the Companys hedges is a $6.5 million letter of credit,
with the remaining credit support under the Revolving Credit Facility through intercreditor agreements. Based on the Companys third party engineering report, the Company had approximately 50% of its remaining 2008 estimated natural gas
production hedged and 24% of its 2009 estimated natural gas production hedged as of June 30, 2008.

The Company recorded a short-term
and a long-term derivative liability of $11.9 million and $2.6 million, respectively, related to the difference between hedged commodity prices and market prices on hedged volumes as of June 30, 2008, after application of SFAS No. 157. All
of the Companys derivative instruments have been designated as cash flow hedging instruments and are deemed to be highly effective. The Company recognized unrealized losses in the statement of operations for the six months ended June 30,
2008 of $1.9 million related to the time value of the costless collars and did not recognize any ineffectiveness on the cash flow hedges. The Company records time value on the costless collars designated as cash flow hedges currently in earnings, as
it has elected to exclude time value from its assessment of hedge effectiveness.

9. Income Taxes

Due to the Companys significant net operating loss carryforwards, the Company did not record any income tax expense for the six months ended June 30, 2008 and 2007. The Company fully reserves its deferred
tax asset through a valuation allowance.

10. Fair Value Measurements

Fair Value Measurements.In September 2006, the FASB issued SFAS No. 157, which defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements.
SFAS No. 157 applies to other accounting pronouncements that require or permit fair value measurements; however, it does not require any new fair value measurements.

SFAS No. 157 establishes a valuation hierarchy for disclosure of the inputs to valuation used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows:



| |  |  | Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities.
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or
indirectly through market corroboration, for substantially the full term of the financial instrument.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 3 inputs are measured based on prices or valuation models that require inputs that are both significant to the fair value measurement and less observable from
objective sources. The

| | Companys valuation models consider various inputs including (a) quoted forward prices for commodities, (b) time value, (c) volatility
factors and (d) current market and contractual prices for the underlying instruments. Level 3 instruments are natural gas zero cost collars. Although the Company utilizes third party broker quotes to assess the reasonableness of prices and
valuation techniques, the Company does not have sufficient corroborating market evidence to support classifying these assets and liabilities as Level 2.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

A financial assets or liabilitys classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The determination of the fair values
below incorporates various factors required under SFAS No. 157, including the impact of our nonperformance risk on our liabilities. The following table provides the assets and liabilities carried at fair value measured on a recurring basis as
of June 30, 2008:

11. Earnings or Loss per Share

In accordance with the provisions of Statement of Financial Standards No. 128 Earnings per Share, basic earnings or loss per share is computed on the basis of the weighted average number of common
shares outstanding during the periods. Diluted earnings or loss per share is computed based upon the weighted average number of common shares plus the assumed issuance of common shares for all potentially dilutive securities. Diluted amounts are not
included in the computation of diluted loss per share, as such would be anti-dilutive.

GeoStar Corporation (GeoStar) to settle the look-back dispute and all other related outstanding disputes. The settlement included an upfront cash payment by the Company of approximately $25.7 million, plus the issuance to GeoStar of a
warrant to purchase 10.0 million of the Companys common shares (the Warrant). Pursuant to the settlement, GeoStar assigned to the Company all of GeoStars natural gas and oil interests in West Virginia, while the Company
acknowledged GeoStars clear title to an exploration license (EL 4416) and assigned to GeoStar its interest in an exploration license application (EL 4968), both located in Victoria, Australia. As of the settlement date, EL 4416 and EL 4968 had
no attributable proved reserves or production. In addition, the Company released its claim to GeoStar on approximately 340 acres in East Texas that were in dispute. Certain other corrective lease assignments and releases are being made between the
Company and GeoStar. The Company and GeoStar have mutually agreed to release all claims against each other, their affiliates and current and past officers and directors.

As part of the settlement, GeoStar has the right to farm-in from the Company two Hilltop well
locations in East Texas and received an additional cash payment of approximately $3.2 million. The designated farm-in area is not included in the Companys future Bossier or Knowles drilling plans and does not include any proven or probable
reserves.

The Warrant is exercisable for $2.75 per share in the event that on or before June 11, 2011, the Company sells up to all or
substantially all of its present natural gas and oil interests located in Leon and Robertson Counties in East Texas for net proceeds exceeding $500 million. A sale, or a series of sales, of all or substantially all of the Companys present East
Texas properties prior to June 11, 2011 for $500 million or less will terminate the Warrant. If the Company does not sell all or substantially all of these properties by June 11, 2011, the Warrant will be exercisable for a six-month period
commencing on that date at $3.00 per share. The Company is not obligated to sell any of its East Texas properties and is not currently pursuing any sale of its East Texas assets.

As a result of the settlement with GeoStar, the Company had, net of the fair market value of Australian properties conveyed and the West Virginia
properties received, a net increase in natural gas and oil properties of $31.5 million as of June 30, 2008. Major components of this increase in natural gas and oil properties are as follows:

13. Commitments and Contingencies

Litigation

The Company is party to various litigation matters. The ultimate outcome of the
matters discussed below cannot presently be determined, nor can the liability that could potentially result from an adverse outcome be reasonably estimated at this time. The Company does not expect that the outcome of the following will have a
material adverse effect on its financial position, results of operations or cash flow.

Navasota Resources L.P. (Navasota)
vs. First Source Texas, Inc., First Source Gas L.P. (now Gastar Exploration Texas LP) and Gastar Exploration Ltd. (Cause No. 0-05-451) District Court of Leon County, Texas 12th Judicial District. This lawsuit, dated October 31, 2005,
contends that the Company breached Navasotas preferential right to purchase 33.33% of the Companys interest in certain natural gas and oil leases located in Leon and Robertson Counties and sold to Chesapeake Energy Corporation pursuant
to a transaction closed November 4, 2005. The preferential right claimed is under an operating agreement dated July 7, 2000. The Company contends, among other things, that Navasota neither properly nor timely exercised any preferential
right election it may have had with respect to the inter-dependent Chesapeake transaction. In July 2006, the District Court of Leon County, Texas issued a summary judgment in favor of the Company and Chesapeake. Navasota filed a Notice of Appeal to
the Tenth Court of Appeals in Waco. Oral argument was heard on September 26, 2007 and the Court of Appeals issued its opinion on January 9, 2008 reversing the trial courts rulings and rendering judgment in favor of Navasota on all
counts. The Company and Chesapeake filed a motion for rehearing on February 6, 2008, which was denied on March 18, 2008. The Company and Chesapeake filed a joint Petition for Review in the Texas Supreme Court on May 13, 2008, and
the Texas Supreme Court requested a Response from Navasota,

which was filed on July 16, 2008. The Company and Chesapeake filed a Reply to Navasotas Response on July 31, 2008 and
is awaiting a determination from the Texas Supreme Court on whether the Court will request full briefing on the merits. Pursuant to an agreement between the Company and Chesapeake, any adverse result in this matter should impact only
Chesapeakes assigned leasehold interests. While this matter is pending, it is possible that expenditures incurred, or authorizations for proposed expenditures, for drilling activities on leases which include the disputed interest may remain
unpaid or not be authorized by the non-operators asserting competing ownership rights, which could require the Company to either fund a disproportionate amount of drilling costs at its own risk or postpone its drilling program on affected leases.

Gastar Exploration Texas LP v. John E. McFarlane, et al (Cause No. 0-06-161) 87th Judicial District Court of Leon County, Texas.
This suit is to quiet title to an undivided 25% mineral interest under an oil and gas lease dated December 4, 2003, covering approximately 2,598 gross acres (the Lease). John E. McFarlane and certain other family members
contend that an undivided 25% mineral interest in the lands covered by the Lease are owned in trust by the grandchildren of Fay W. McFarlane and are not covered by the Lease as Gastar claims. McFarlane, et. al., filed an answer to the
Companys petition and also filed several different motions for summary judgment which were denied by the District Court. A day long mediation of this lawsuit occurred on August 24, 2007, but the parties were unable to settle this matter
at that time. The lawsuit is in the discovery phase and is currently set for a non-jury trial on December 2, 2008. The existence of unleased mineral interests in this Lease could adversely impact the future development of the Lease. The Company
will continue to vigorously pursue this claim.

Spencer D. Plummer, III v. GeoStar Corporation, Classic Star LLC, Gastar Exploration,
Ltd., Thom Robinson, Tony Ferguson, and John W. Parrott; In the United States District Court of Utah, Central Division (Case No. 2:07-CV-00409). This lawsuit was filed on May 24, 2007 initially in Utah state court by Spencer
Plummer, or the Plaintiff, in which he asserts breaches of his Employment Agreement and subsequent Termination Agreement (the Agreements) with his employer, Classic Star, a subsidiary of GeoStar. The Plaintiff claims that he has not
received benefits promised under such Agreements, including 699,249 shares of Company stock. The Company is not a party to the Agreements on which Plaintiffs claims are expressly based; however, the Company and Plaintiff are parties to a Stock
Option Agreement on which Plaintiff claim to Company stock is partially based. The Company filed an Answer and Motion to Dismiss for lack of personal jurisdiction in Utah and for Plaintiffs failure to state a claim upon which relief can be
granted. On August 1, 2008, the Kentucky courts granted the Companys Motion to Dismiss.

Craig S. Tillotson v. S. David Plummer 2nd, Spencer Plummer 3rd, Tony Ferguson, John Parrott, Thomas Robinson, GeoStar Corporation, First Source Wyoming, Inc. GeoStar Financial Services Corporation, Gastar Exploration Ltd., Zeus Investments, LLC and John Does 1-10
(Civil No. 080412334).This lawsuit was filed on July 7, 2008 in Utah state court by Craig S. Tillotson, or the Plaintiff, in which he alleges that he was fraudulently induced to invest in a
mare leasing program operated by Classic Star LLC, a subsidiary of GeoStar, on the basis of certain verbal representations, and to convert interests in that program into shares of a working interest in the Powder River Basin. The Plaintiff asserts
causes of action against all defendants including common law fraud, fraudulent inducement, statutory securities fraud under Utah state law, civil conspiracy, and negligent misrepresentation, and asserts certain additional causes of action only
against GeoStar, a GeoStar affiliate, and the Plummers. The Company has not yet answered or otherwise responded. The Company intends to vigorously defend the suit.

Commitments

In March 2008, the Company entered into formal agreements with ETC Texas
Pipeline, Ltd. (ETC) for the gathering, treating, purchase and transportation of the Companys natural gas production from the Hilltop area of East Texas. These agreements are effective September 1, 2007 and have a term of 10
years. ETC currently provides the Company 50 MMcfd of treating capacity and 120 MMcfd of gathering capacity. The Company has the right to request ETC build, at their cost, up to 150 MMcfd of treating and gathering capacity during the term of the
agreement, provided that the Companys production equals 85% of the then existing treating and gathering capacity for a 30 day period. The Company may at any time elect to have its treating and gathering capacity increased subject to cost
indemnifications to ETC.

Additional treating and gathering capacity requests must be in at least 25 MMcfd and 5 MMcfd increments, respectively. In addition, the Company must furnish
to ETC information that reasonably demonstrates that its projected production for the five years after expansion is sufficient to warrant the costs to create the expanded treating and gathering capacity. The incremental volume increases in treating
and gathering capacity shall be subject to marginal increases in treating fees. Pursuant to the agreements, the Company has access up to 150 MMcfd of firm transportation on ETCs system or the pipelines of its affiliates or subsidiaries from
the tailgate of the treating facility to Katy Hub. The Company has the option to sell and ETC has the obligation to buy, up to 150 MMcfd of the Companys Hilltop production at delivery points upstream of ETCs gathering and treating
facilities. The Company does not have an obligation to deliver to ETC volumes in excess of 150 MMcfd, but should ETC elect to purchase such excess volumes, purchases will be subject to the treating and gathering expansion terms set forth in the
agreements.

Registration Obligation

On November 29, 2007, Gastar USA sold $100.0 million aggregate principal amount of 123/4% Senior Secured Notes at an issue price of 99.50% in a private placement to qualified institutional buyers. In connection with the
sale, Gastar USA, the Company and all of Gastar USAs existing domestic subsidiaries entered into a registration rights agreement providing for the exchange of new notes registered under the Securities Act of 1933, as amended (the
Securities Act). On August 4, 2008, the Company completed the exchange offer in which it issued $100.0 million aggregate principal amount of new 123/4% Senior Secured Notes due 2012 registered under the Securities Act in exchange for all of the old notes.

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

Overview

We are an independent energy company engaged
in the exploration, development and production of natural gas and oil in the United States and Australia. Gastar pursues a strategy combining select higher risk, deep natural gas exploration prospects with lower risk coal bed methane (CBM)
development. Gastar owns and operates exploration and development acreage in the deep Bossier gas play of East Texas and has recently commenced exploration operations in the Marcellus Shale play in West Virginia and Pennsylvania. Gastars CBM
activities are conducted within the Powder River Basin of Wyoming and Montana and on approximately 6.0 million gross acres controlled by us and our joint development partner in Australias Gunnedah Basin, located in New South Wales.

Hilltop Area, East Texas

Hilltop
Area, East Texas. The majority of our drilling activities have been in the deep Bossier and Knowles Limestone plays in the Hilltop area, located in East Texas approximately midway between Dallas and Houston in Leon and Robertson Counties.
This exploration play has attracted some of the largest and most active operators in the United States. Wells in this area target multiple potentially productive natural gas formations and are typically characterized by high initial production,
significant decline rates and long-lived reserves.

Our first successful operated well was spudded in 2003 and placed on production in
September 2004. As of June 30, 2008, we had successfully completed 16 out of 17 deep Bossier wells and five out of five Knowles Limestone wells. As of June 30, 2008, we were drilling 1 gross (0.5 net) Bossier well and 1 gross (0.5 net)
Knowles Limestone well.

During the three months ended June 30, 2008, we completed the drilling of the Lone Oak Ranch #6, or LOR #6,
well to a total depth of 16,475 feet and, based on drilling and log analysis, we encountered two productive middle Bossier sands. The well was initially completed in the deepest pay zone and placed on production at a gross sales rate of 17.5 MMcfd
with flowing casing pressure of 9,200 psi. The well was subsequently completed in the upper zone and is currently producing at a rate of 10.6 MMcfd with flowing casing pressure of 6,200 psi. We are currently evaluating the optimal time to co-mingle
the production from both zones. Gastar has a 50% working interest before payout (approximately 37.5% net revenue interest) in the LOR #6 well.

During the quarter, we also side-tracked and completed the LOR #4, a horizontal Knowles Limestone well, which currently is producing at a stabilized gross stabilized sales rate of 1.2 MMcfd. Gastar has a 50.0% working interest
(approximately 37.5% net revenue interest) in the LOR #4 well.

##### Table of Contents

The Brunette #1, a horizontal Knowles Limestone well, was drilled to a total measured depth of 15,251
feet (total vertical depth of 13,341 feet). The well encountered approximately 640 feet of reservoir quality formation within the 1,367-foot horizontal section of the wellbore. The Brunette #1 was stimulated and placed on production in mid-April
2008 and is currently producing at a gross stabilized rate of 0.3 MMcf per day. The well appears to have mechanical problems, and we anticipate initiating workover procedures in the near future.

Currently, we are drilling one deep Bossier well, the Belin #1, (an offset to the Wildman #3) and one middle Bossier well, the Lone Oak Ranch #7, (an
offset to the LOR #6).

For the three and six months ended June 30, 2008, net production from the Hilltop area averaged 16.4 MMcfe per
day and 18.6 MMcfe per day, respectively. For the balance of 2008, we anticipate a two-rig drilling program in East Texas focused on drilling Bossier wells offsetting recent successful wells.

Marcellus Shale  West Virginia and Pennsylvania

The Marcellus Shale, is a black shale of Middle Devonian age that underlies much of Pennsylvania, New York, Ohio, West Virginia and adjacent states. The depth of the Marcellus Shale and its low permeability have historically made the
Marcellus an unconventional exploration target. Within the past few years, two technologies, hydrofracing and horizontal drilling, have been tested in the Marcellus Shale with very promising results. These developments have resulted in increased
leasing and drilling activity in the area. In late 2007, we began acquiring an acreage position in the Marcellus Shale in West Virginia and Eastern Pennsylvania. For the remainder of 2008, we plan to continue to build our lease acreage position in
this area. We anticipate that drilling in the Marcellus Shale will commence in late 2008 or early 2009.

Coalbed Methane  Powder River Basin,
Wyoming and Montana

We own an approximate 40% average non-operated working interest in approximately 55,000 gross (21,900 net) acres in
the Powder River Basin of Wyoming and Montana. Generally, CBM wells are shallow and less costly than conventional natural gas wells. Our primary areas of activity in the Powder River Basin are the Squaw Creek, Ring of Fire and adjacent fields, all
of which are located north of Gillette, Wyoming in an active drilling area.

We had no drilling activity in the Powder River Basin during
the three months ended June 30, 2008 but anticipate an increase in capital activity later this year. For both of the three and six months ended June 30, 2008, our average net production from our CBM properties in the Powder River Basin was
approximately 5.5 MMcf per day.

Coalbed Methane  PEL 238, Gunnedah Basin, New South Wales, Australia

We have a 35% interest in PEL 238, a CBM exploratory property covering approximately 2.2 million gross (786,000 net) acres, located in the Gunnedah
Basin of New South Wales (NSW), approximately 250 miles northwest of Sydney, Australia, near the town of Narrabri. We believe that the strategic location of the properties and potential CBM reserves near the large natural gas markets in
the Sydney-Newcastle-Wollongong area and the concessions location relative to other developing gas markets should create a competitive marketing advantage for the natural gas reserves that may be developed on PEL 238.

During 2006, we participated with our joint venture partner and license operator, Eastern Star Gas Limited (ESG), in the drilling of eight
new vertical coal seam natural gas wells on approximately 40-acre spacing in close proximity to an existing well within the Bohena Project Area of PEL 238 and one additional monitoring well. The results from the pilot production phase of the program
have been positive, with the results confirming the high measured permeability of the coal and the presence of natural gas in the coal.

##### Table of Contents

During 2007, we and ESG were approached by potential buyers with an interest in potentially contracting
for up to 1.0 Tcf of natural gas from PEL 238 to be delivered over a 15 to 20-year period commencing in late 2010, though there is no assurance that such an agreement will ultimately be reached or that such volumes will ultimately be produced from
PEL 238. In March 2007, we announced that we and ESG had executed a Memorandum of Understanding (MOU) with Macquarie Generation, a New South Wales government-owned electricity generator, for the potential future supply of natural gas for
its Bayswater power station. In November 2007, we announced that we and ESG had entered into a second MOU with Babcock & Brown to supply gas from the PEL 238 and PEL 433 concessions for use in the generation of electricity.

In September 2007, our independent petroleum engineers, Netherland Sewell & Associates, Inc., certified a quantity of proved and probable
reserves under guidelines established by the Society of Petroleum Engineers, as a result of the success of one of our pilot production projects on PEL 238. These reserves, however, are not yet established as proved reserves under Securities and
Exchange Commission, or SEC, guidelines nor can we assure that other unevaluated acreage will contain similar reserves.

Beginning in 2008,
we and ESG expanded our pilot production drilling program in the Bohena Project Area of PEL 238 and have successfully completed the drilling of the first three test coreholes, the Dewhurst #2, #3 and #4, in a 20-corehole exploration and appraisal
drilling program on PEL 238. The results of the coreholes confirmed the presence of a thick Bohena coal seam developed to the south and east of the Bibblewindi pilot production area. The Dewhurst #2 encountered approximately 39 meters of coal within
the Black Jack and Maules Creek coal formations, including approximately 18 meters in the targeted Bohena seam of which 14.7 meters was found in a single coal zone. The Dewhurst #3 encountered approximately 39 meters of coal within the Black Jack
and Maules Creek coal formations, including approximately 17 meters in the targeted Bohena seam. We recently finished drilling the third corehole, the Dewhurst #4. The well encountered 39 meters of coal within the Black Jack and Maules Creek
formations, including 16 meters in the Bohena seam. We are currently drilling the Dewhurst #7.

In late June 2008, we announced, subject to
certain approvals, an agreement to acquire a 35% interest in the Wilga Park Power Station in New South Wales, Australia from ESG, which owns the remaining 65% interest. This acquisition aligns both of our ownerships in PEL 238 and the Wilga Park
Power Station. The power station is located approximately 20 miles north of the Bohena Project Area of PEL 238. The acquisition also includes a 35% working interest in Petroleum Production License 3, which contains the Coonarah conventional gas
field. Upon closing, anticipated in the third quarter of 2008, we will pay $3.0 million in cash to ESG, with an additional payment of $250,000 contingent upon the Wilga Park Power Station being successfully expanded to a capacity of seven megawatts
(MW). The facility currently has a capacity of four MW with plans in place to gradually increase capacity up to 40 MW as coal seam gas production from PEL 238 increases. Construction of a flowline to deliver gas from the PEL 238
production pilots to the power station is in the final stages of permitting and right-of-way acquisition and is expected to be completed by the end of 2008. The power station will be the primary market for natural gas from PEL 238 until we begin
fulfilling our supply arrangements under the two previously announced MOUs.

In July 2008, we and ESG entered into a Heads of Agreement
(HoA) with the APA Group (APA), owner of the Central West and Moomba Sydney Gas Pipelines. Under the HoA, options for early delivery of coal seam gas from PEL 238 into NSW gas market are to be investigated. Under the HoA, it
is anticipated that coal seam gas would be initially delivered to New South Wales gas markets via APAs Central West Pipeline, with APAs NSW pipeline system to subsequently be expanded as gas production and markets grow. By matching gas
production, pipeline and market requirements in this manner, we and ESG believe we can minimize capital requirements, while realizing favorable gas transportation tariffs.

Coal Bed Methane  PEL 433-434, Gunnedah Basin, New South Wales, Australia

PEL 433 and PEL 434
are located adjacent to our PEL 238 project and cover approximately 3.8 million gross (1.3 million net) acres. Coal evaluation core-hole drilling completed during the 1970s and

##### Table of Contents

1980s by the New South Wales government identified the distribution and thickness of the coal measures within a portion of PEL 433. The Hoskissons Coal Seam
is believed to be approximately 4 to 6 meters thick and widely distributed within the eastern part of PEL 433. There has been no previous coal seam gas exploration and evaluation work in the area, and there is no information on gas content, gas
composition or coal permeability.

In July 2007, we entered into a Farm-In Agreement with ESG under which we have earned a 35% working
interest in the PEL 433 and PEL 434. Under the terms of the Farm-In Agreement, we paid the costs of a two core-hole program on PEL 433 and the related costs of the evaluation of the coal reservoirs intersected by the core-holes. A two corehole
drilling program, designed to evaluate the coal seam gas permeability, gas content and gas composition, was completed in early 2008. The results from these wells showed good coal development, gas composition and excellent permeability in the area.
Gas contents were low due to the shallow dept of the coal. Further investigation is underway to identify areas with improved gas content. Analysis of the core samples is continuing. This two corehole program fulfilled the first year capital
expenditure commitment for PEL 433.

Both PEL 433 and 434 are set to expire February 2009. We and ESG plan to submit a renewal application
including a drilling program to meet work commitment during the term of the renewal. As is customary, we and ESG anticipate that a renewal will necessitate a relinquishment of up to 25% of our current acreage.

Three Months Ended June 30, 2008 compared to the Three Months Ended June 30, 2007

Revenues.Substantially all of our revenues are derived from the production of natural gas in the United States. Natural gas
and oil revenues were $15.9 million for the three months ended June 30, 2008, up 100% from $8.0 million for the three months ended June 30, 2007. Of the increase in revenues, 49% was the result of a 49% increase in production volumes,
primarily in East Texas, and 51% was due to a 34% increase in prices. During the three months ended June 30, 2008, approximately 61% of our total natural gas production was hedged. The realized effect of hedging on natural gas sales was a
decrease of $2.6 million in revenues, resulting in a decrease in total price received from $9.01 per Mcf to $7.71 per Mcf.

Unrealized
natural gas hedge loss of $513,000 is related to the time value of the costless collars. For the remainder of 2008, we have approximately 50% of our estimated natural gas production hedged.

Production taxes. We reported production taxes of $474,000 for the three months ended
June 30, 2008, compared to $220,000 for the three months ended June 30, 2007. The increase in production tax was primarily the result of higher production and prices, primarily in Wyoming, and a severance tax refund in the second quarter
of 2007 for our Texas wells.

Lease operating expenses. We reported lease operating expenses of $2.4 million for the three months
ended June 30, 2008, up from $1.5 million for the three months ended June 30, 2007. Our lease operating expenses were $1.18 per Mcfe for the three months ended June 30, 2008, compared to $1.10 per Mcfe for the comparable period in
2007. The increase in total lease operating expenses was due to an increase in Texas workover costs coupled with higher production volumes. During the current quarter, workover costs totaled $952,000, or $0.47 per Mcfe, as compared to $276,000, or
$0.20 per Mcfe for the same period in 2007. Excluding workover costs, lease operating costs for the three months ended June 30, 2008 were $0.71 per Mcfe, as compared to $0.90 per Mcfe for the same period in 2007.

Transportation and treating. We reported transportation expenses of $498,000 for the three months ended June 30, 2008, up from $339,000 for
the three months ended June 30, 2007. This increase was primarily due to increased production and prices of natural gas in Wyoming.

Depreciation, depletion and amortization. We reported depreciation, depletion and amortization (DD&A) of $5.9 million for the three months ended June 30, 2008, up from $5.4 million for the three months ended
June 30, 2007. The increase in DD&A expense was primarily the result of an increase in production volumes of 49%. The DD&A rate for the three months ended June 30, 2008 was $2.88 per Mcfe, as compared to $3.97 per Mcfe for the
comparable period in 2007.

Impairment of natural gas and oil properties. There was no impairment of natural gas and oil properties
recorded during the three months ended June 30, 2008. We recorded a $28.5 million impairment of natural gas and oil properties for the three months ended June 30, 2007. The weighted average natural gas price utilized for the June 30,
2007 ceiling impairment evaluation was $5.75 per Mcf, held constant.

General and administrative. We reported general and
administrative expenses of $4.1 million for the three months ended June 30, 2008, up from $3.5 million for the three months ended June 30, 2007. The increase in general and administrative expenses was primarily due to an increase in legal
costs and higher personnel costs. Legal costs related to the GeoStar litigation totaled approximately $968,000 in the current quarter an increase of $859,000 from the same period in 2007. Non-cash stock-based compensation expense pursuant to the
SFAS 123R, which is included in general and administrative expenses, was $855,000 and $931,000 for the three months ended June 30, 2008 and 2007, respectively.

Interest expense. We reported interest expense of $1.9 million for the three months ended
June 30, 2008, compared to $3.7 million for the three months ended June 30, 2007. The decrease in interest expense was primarily the result of $2.6 million of interest being capitalized during the three months ended June 30, 2008,
resulting from capital activity expansion, which was partially offset by higher interest expense on the new 123/4% Senior
Secured Notes. There was no capitalized interest recorded for the comparable period in 2007.

Gain on sales of natural gas and
oil properties. In May 2007, we sold a portion of our undeveloped natural gas and oil acreage in the Hilltop area of East Texas for approximately $68.2 million before transaction costs of approximately $1.4 million, resulting in a gain on sale
of $38.9 million.

Six Months Ended June 30, 2008 compared to the Six Months Ended June 30, 2007

Revenues. Substantially all of our revenues are derived from the production of natural gas in the United States. Natural gas and oil revenues were
$32.7 million for the six months ended June 30, 2008, up 112% from $15.5 million for the six months ended June 30, 2007. Of the increase in revenues, 62% was the result of a 69% increase in production volumes, primarily in East Texas, and
38% was due to a 25% increase in prices. During the six months ended June 30, 2008, approximately 51% of our natural gas production was hedged. The realized effect of hedging on natural gas sales was a decrease of $2.9 million in revenues,
resulting in a decrease in total price received from $7.95 per Mcf to $7.30 per Mcf.

Unrealized natural gas hedge loss of $1.9 million is related to the time value of the costless collars.
For the remainder of 2008, we have approximately 50% of our estimated natural gas production hedged.

Production taxes. We reported
production taxes of $743,000 for the six months ended June 30, 2008, compared to $514,000 for the six months ended June 30, 2007. The increase in production taxes was the result of higher production and prices, primarily in Wyoming, and a
severance tax refund in the second quarter of 2007 for our Texas wells.

Lease operating expenses. We reported lease operating
expenses of $4.0 million for the six months ended June 30, 2008, up from $3.2 million for the six months ended June 30, 2007. Our lease operating expenses were $0.89 per Mcfe for the six months ended June 30, 2008, compared to $1.21
per Mcfe for the comparable period in 2007. The increase in total lease operating expenses was due to higher Texas workover costs coupled with higher production volumes. During the current period, workover costs totaled $933,000, or $0.21 per Mcfe,
as compared to $331,000, or $0.13 per Mcfe during the same period in 2007. Excluding workover costs, lease operating costs for the six months ended June 30, 2008 was $0.68 per Mcfe, as compared to $1.08 per Mcfe for the same period in 2007.

Transportation and treating. We reported transportation expenses of $957,000 for the six months ended June 30, 2008, up from
$662,000 for the six months ended June 30, 2007. This increase was primarily due to increased production and prices in Wyoming.

Depreciation, depletion and amortization. We reported DD&A of $12.3 million for the six months ended June 30, 2008, up from $9.8 million for the six months ended June 30, 2007. The increase in DD&A expense was the
result of a 69% increase in production, primarily attributable to new East Texas wells. The DD&A rate for the six months ended June 30, 2008 was $2.76 per Mcfe, as compared to $3.70 per Mcfe for the comparable period in 2007.

Impairment of natural gas and oil properties. There was no impairment recorded during the six months ended June 30, 2008. We recorded a $28.5
million impairment of natural gas and oil properties for the six months ended June 30, 2007. The weighted average natural gas price utilized for the June 30, 2007 ceiling impairment evaluation was $5.75 per Mcf, held constant.

General and administrative. We reported general and administrative expenses of $8.3 million for the six months ended June 30, 2008, down
from $10.3 million for the six months ended June 30, 2007. This decrease in general and administrative expenses was primarily due to a $3.6 million allowance for doubtful accounts established for certain GeoStar receivables during the six month
period ended June 30, 2007. Excluding this GeoStar allowance, general and administrative expenses were up $1.6 million due to higher legal and personnel costs. Legal costs related to the GeoStar litigation totaled approximately $1.7 million for
the six months ended June 30, 2008, an increase of $1.6 million for the same period in 2007. Non-cash stock-based compensation expense pursuant to the SFAS 123R, which is included in general and administrative expenses, was $1.7 and $2.2
million for the six months ended June 30, 2008 and 2007, respectively.

Litigation settlement expense. There was no litigation
settlement expense for the six months ended June 30, 2008. The $1.4 million litigation settlement expense incurred in the six months ended June 30, 2007 was primarily the result of an accrual related to a proposed settlement with GeoStar
on certain matters, which was not settled during the period.

Interest
expense. We reported interest expense of $4.0 million for the six months ended June 30, 2008, compared to $7.7 million for the six months ended June 30, 2007. The decrease in interest expense was primarily the result of $5.0 million of
interest being capitalized during the six months ended June 30, 2008, resulting from capital activity expansion, which was partially offset by higher interest expense on the new 123/4% Senior Secured Notes. There was no capitalized interest recorded for the comparable period in 2007.

Liquidity and Capital Resources

At June 30, 2008, we had cash and cash equivalents of $42.0 million. The administrative agent to our Revolving Credit Facility has recently approved, subject to the agreement of our other syndication banks, an
increase in our borrowing base to $45.0 million, of which $6.5 million is being utilized as collateral for a letter of credit to support the Companys hedging activities. This increase will provide us with an additional $38.5 million of
borrowing capacity availability under our Revolving Credit Facility. For the six months ended June 30, 2008, we reported cash flow from operations of $24.3 million, up from $5.7 million of cash flow from operations for the six months ended
June 30, 2007. This increase resulted primarily from a 69% increase in production volumes and a 25% increase in prices. Capital expenditures on natural gas and oil properties totaled $66.2 million for the six months ended June 30, 2008,
including $25.8 million related to the GeoStar settlement regarding the look-back dispute.

Covenants in our 123/4% Senior Secured Notes indenture, our indenture governing our 9.75% convertible senior unsecured
subordinated debentures and our Revolving Credit Facility agreement require us to make an offer to repurchase or repay all of the outstanding indebtedness thereunder in the event of a change of control of the Company, as defined in the respective
agreements. Each of the indentures provides that if there is a change of control of the Company, we are required to make an offer to each holder to repurchase all or any part of the 123/4% Senior Secured Notes or the 9.75% convertible senior unsecured subordinated debentures, as the case may be, at 101% of the aggregate principal amount of the notes or
debentures tendered for repurchase, plus accrued and unpaid interest. In the event of a change of control, as defined in the Revolving Credit Facility agreement, all obligations under the Revolving Credit Facility will become immediately due and
payable. If the change of control event occurs in one or more of these agreements, we may not have adequate financing available to meet the resulting payment obligations.

We continually evaluate our capital needs and compare them to our capital resources. To execute our operational plans in East Texas, Appalachia and
Australia, additional funds will be needed for acreage acquisition, seismic and other geologic analysis, drilling, undertaking completion activities and for general corporate purposes. We may have to significantly reduce our drilling and development
program if our internally generated cash flow from operations and cash flow from financing activities are not sufficient to pay debt service, corporate overhead and expenditures associated with our projected drilling and development activities. We
expect to fund these expenditures from internally generated cash flow, cash on hand, sales of assets and the issuance of additional debt or equity. We may also attempt to balance future capital expenditures through joint venture development of
certain properties with industry partners. We cannot be certain that future funds will be available to fully execute our current business plan.

Based on our current budget, we have sufficient capital, together with internally generated cash flow and borrowing capacity under our existing Revolving Credit Facility to fund our exploration and development activities in United States
and Australia for the remainder of 2008. We anticipate having to secure additional funding of $50.0 to $80.0 million to fund our current budgeted 2009 capital program, including capital required for additional acreage acquisitions and exploration
activities in West Virginia and Eastern Pennsylvania, and related debt maturities. The funding of any capital short fall could include non-strategic asset sales, promoting a joint venture partner on our properties outside of Texas, and additional
debt or equity issuances.

Our cash flow and ability to raise capital are highly
dependent upon natural gas pricing. A material decrease in current and projected natural gas prices could impact our ability to fund future activities, impair our ability to raise additional capital on acceptable terms and result in a financial
covenant default under the our Revolving Credit Facility or 123/4% Senior Secured Notes, resulting in mandatory principal
reduction under certain conditions.

##### Table of Contents

In 2007 and 2008, we entered into various costless collar transactions with counterparties. The volumes
currently hedged represent approximately 50% of our remaining 2008 projected production and 24% of our 2009 projected production.

A
covenant in our Revolving Credit Facility agreement restricts us from hedging more than 85% of the projected natural gas production from proved developed producing reserves.

At June 30, 2008, we were in compliance with all debt covenants.

Off Balance Sheet Arrangements

As of June 30, 2008, we had no off balance sheet arrangements.
We have no plans to enter into any off balance sheet arrangements in the foreseeable future.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with accounting US GAAP requires management to make estimates and assumptions that affect
the reported amounts of assets, liabilities, revenues, expenses, contingent assets and liabilities and the related disclosures in the accompanying condensed consolidated financial statements. Changes in these estimates and assumptions could
materially affect our financial position, results of operations or cash flows. Management considers an accounting estimate to be critical if:



| |  |  | It requires assumptions to be made that were uncertain at the time the estimate was made; and
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | Changes in the estimate or different estimates that could have been selected could have a material impact on our consolidated results of operations or financial
condition.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Significant accounting policies that we employ and information about the nature of our most critical
accounting estimates, our assumptions or approach used and the effects of hypothetical changes in the material assumptions used to develop each estimate are presented in Note 2 to our condensed consolidated financial statements in our Annual Report
on Form 10-K for the year ended December 31, 2007.

For information as to new accounting pronouncements, see Note 1 to our condensed
consolidated financial statements in this Form 10-Q.



|Item 3. | Quantitative and Qualitative Disclosure About Market Risk
|------- | ---------------------------------------------------------

Commodity Price Risk

Our major commodity price risk exposure is to the prices received for our
natural gas production. Realized commodity prices received for our production are the spot prices applicable to natural gas in the region produced. Prices received for natural gas are volatile and unpredictable and are beyond our control. We have
entered into hedge transactions to mitigate our commodity pricing risk. For the six months ended June 30, 2008, a 10% change in the prices received for natural gas production would have had an approximate $3.5 million impact on our revenues
before mitigating factors that might result from having hedge transactions in place. See Note 5 to our condensed consolidated financial statements for additional information on our commodity hedging activities.

Interest Rate Risk

The carrying value of our debt
approximates fair value. At June 30, 2008, we had approximately $133.3 million in principal amount of long-term debt, all of which was at a fixed interest rate. A 10% fluctuation in interest rates would have no impact on our annual interest
expense.

Currency Translation Risk

Our revenues and expenses and the majority of our capital expenditures are primarily in United States dollars, thus limiting our exposure to currency translation risk. During the six months ended June 30, 2008,
we spent approximately $3.1 million of capital expenditures on our Australian activities. We have no plans in the foreseeable future to implement hedges or financial instruments to manage international currency changes.



|Item 4. | Controls and Procedures
|------- | -----------------------

Managements
Evaluation on the Effectiveness of Disclosure Controls and Procedures

As required by SEC Rule 13a-15(b), we have evaluated, under the
supervision and with the participation of our management, including our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules
13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Form 10-Q. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by us in reports
we file under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure and is recorded,
processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were effective as of
June 30, 2008 at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting during the quarter ended June 30, 2008 that materially affected, or is
reasonably likely to materially affect, our internal control over financial reporting.
