GASTAR EXPLORATION LTD. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

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 consolidated financial statements in its Annual Report on Form 10-K for the year ended December 31, 2005. Such policies have been continued without change except for the adoption of Financial Accounting
Standards Board (FASB) SFAS 123R, Shared Based Payments (SFAS 123R). 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 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, 2006 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 (U.S.) dollars unless otherwise noted and have been prepared by management in accordance with accounting principles generally accepted
in the United States of America (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 periods has been reclassified to conform to the presentation adopted in 2006.

2. Deferred Charges

Deferred financing charges include costs of debt financings undertaken by the Company including
commissions, legal fees and other direct costs of the financing. Using the interest method, the deferred financing charges are amortized over the term of the related debt. Deferred leasing charges represent future demobilization and transportation
costs of leased natural gas treatment plants in East Texas. The deferred leasing charges are amortized into lease operating expense over the term of the agreements.

The following table sets forth information regarding deferred charges for the period indicated:

Senior Secured Notes

On June 17, 2005,
the Company issued $63.0 million in principal amount of senior secured notes (Senior Secured Notes). On September 19, 2005, the Company issued to the holders of the Senior Secured Notes an additional $10.0 million of Senior Secured
Notes on substantially the same terms as the original June 2005 private placement. The Senior Secured Notes are secured by substantially all of the Companys assets, bear interest at the sum of the three-month LIBOR rate plus 6% (11.48% at
June 30, 2006), payable quarterly and mature five years and one day from the date of issuance. The Senior Secured Notes are redeemable in whole or in part prior to maturity at the Companys option at any time after the first anniversary
date of issuance upon payment of the principal and accrued and unpaid interest plus a premium ranging from 5% to 3% of redeemed principal; provided that, a redemption at the Companys option is not permitted following the public announcement of
certain pending, proposed or intended change of control transactions.

In connection with the Senior Secured Notes issuances, the Company
agreed to issue to the note holders, for no additional consideration, common shares in increments valued at CDN$4.5 million with respect to the $63.0 million of Senior Secured Notes and additional common shares in increments valued at CDN$714,286
with respect to the $10.0 million of Senior Secured Notes at closing and on each of the six, twelve and eighteen-month anniversaries of the closing date, valued on a five day weighted average trading price immediately prior to the date of issuance.
On March 20, 2006, the six-month anniversary of the September 19, 2005 $10.0 million Senior Secured Notes issuance, the Company issued to the note holders an additional 152,299 common shares at CDN$4.69 per share. On June 19, 2006,
the twelve-month anniversary of the June 17, 2005 $63.0 million Senior Secured Notes issuance, the Company issued to the note holders an additional 1,607,143 common shares at CDN$2.80 per share. The issuance of common shares was recorded based
on their fair issuance values recorded to common shares issued and a corresponding reduction in the liability to be settled by the issuance of common shares.

The Company has the right on a quarterly basis to require the note holders to purchase up to an aggregate of $10.0 million principal amount of additional Senior Secured Notes through June 16, 2007. If additional
Senior Secured Notes are issued, the note holders will be entitled to receive, for no additional consideration, additional common shares on similar terms as those issued with the original Senior Secured Notes in a pro rata amount based on the
additional principal amount of the Senior Secured Notes.

Debentures). The Convertible Senior Debentures have a term of five years, bear interest at 9.75% per annum, payable quarterly and mature on November 20, 2009. The Convertible Senior Debentures are convertible by the holders into
common shares at a conversion price of $4.38 per share. The Convertible Senior Debentures are not redeemable by the Company on or before November 12, 2006, except in the event of the satisfaction of certain conditions after a change of
control, as defined in the Trust Indenture. After November 12, 2006, the Convertible Senior Debentures may be redeemed at any time by the Company at a redemption price equal to par plus accrued and unpaid interest; provided that, the

8. Share Based Compensation

Share-based compensation 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 ten years. Vesting generally occurs over a four-year period at 25% per year. Once exercisable, the employee may purchase common shares of the Company at the
market price on the date the option was granted. New common shares are issued in regards to stock option exercises.

On June 1, 2006, at annual meeting of shareholders, the 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 to directors, officers and employees of the Company and its subsidiaries to purchase a maximum of
5.0 million common shares. The contractual life and vesting period for options granted will be determined by the Board of Directors at the time stock options are granted. As of June 30, 2006, no stock options had been granted under the
2006 Gastar Long Term Stock Incentive Plan.

Effective January 1, 2003, the Company adopted the provisions of SFAS No. 123,
Accounting for Stock-Based Compensation, using the modified prospective application method. In December of 2004, the FASB issued SFAS 123R which addressed the accounting for transactions in which an entity exchanges its equity
instruments for goods and services. It also addressed transactions in which an entity incurs liabilities in exchange for goods or services that are based on the fair value of the entitys equity instruments or that may be settled by the
issuance of those equity instruments. This statement supersedes APB Opinion No. 25 and requires a public entity to measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value
of the award. That cost is recognized over the period during which an employee is required to provide service in exchange for the award  the requisite service period (usually the vesting period). Because the Company had previously adopted SFAS
123 and recorded the fair value of stock options granted after January 1, 2003, SFAS 123R had minimal impact upon adoption effective January 1, 2006.

Determining Fair Value Under SFAS No. 123R

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 amortized on a straight-line basis over the requisite service periods, which are generally the vesting periods.

Expected Life. The expected life of awards granted represents the period of time that stock options are expected to be outstanding. The Company
determines the expected life using the simplified method in accordance with Staff Accounting Bulletin No. 107 for all stock options issued with ten-year grant expiration. An expected life of five years was utilized for all stock
options with five-year grant expiration.

Expected Volatility. Using the Black-Scholes-Merton valuation model, the Company estimates
the volatility of its common shares at the date of grant based on its historical volatility.

Risk-Free Interest Rate. The Company
assumes a risk-free interest rate of 5.0% in the Black-Scholes-Merton option valuation model, which approximates the implied yield currently available on U.S. Treasury zero-coupon issues with an equivalent remaining term equal to the expected life
of the award.

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. To date the Company has had limited forfeitures and thus has not included expected forfeitures in determining compensation expense.

The fair value of each option grant is estimated on the date of grant using the Black-Scholes-Merton
valuation pricing model. During the first six months of 2006 and 2005, we granted 1,195,000 and 426,000 stock options, respectively. A summary of the weighted average assumptions and results for stock options granted during the six months ended

Share Based Compensation

For the three months ended June 30, 2006 and 2005, the Company recorded $772,000 and $748,000, respectively, in stock-based compensation expense for
stock options granted using the fair-value method. For the six months ended June 30, 2006 and 2005, the Company recorded $1.3 million and $1.5 million, respectively, in stock-based compensation expense for stock options granted using the
fair-value method and $7,500 for director fees waived during the during the first six months of 2006. All stock based compensation costs were expensed and not tax effected as the Company currently records no tax expense.

At June 30, 2006, the Company had unvested stock options to purchase 5,439,500 shares with a weighted average grant date fair value of $1.14. As of
June 30, 2006, the Company had approximately $2.3 million of total unrecognized compensation cost related to unvested stock options, which is expected to be amortized over the following periods:

9. Loss per Share

In accordance with the provisions of SFAS No. 128, Earnings per Share, basic earnings per share is computed on the basis of the weighted average number of common shares outstanding during the periods.
Diluted earnings 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.

12. Commitments and Contingencies

Litigation

The Company is party to various litigation matters arising out of the normal
course of business. The ultimate outcome of each of these matters 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 these proceedings will have a material adverse effect on its financial position or results of operations. The more significant litigation matters are summarized below.

Estate of Virgil Sparks and Oil Wells of Kentucky, Inc. vs. First Sourcenergy Group Inc. and Geostar Corporation Arbitration. In August 2002, FSG,
a wholly owned Company subsidiary, was a named party to this arbitration proceeding. The dispute involves historical dealings with the development of an Authority to Prospect (ATP) Area in Queensland, Australia, as well as an ancillary
agreement. The formal arbitration is in discovery stages. FSG and GeoStar have moved to dismiss the arbitration on the grounds of a claimed prior settlement and release agreement. FSG and GeoStar are vigorously defending the arbitration, and firmly
believe that its position is sound and intends to continue to defend vigorously against the claim. Further, FSGs interest in ATP 560 were transferred from FSG to a third party in 2001, the result of which means that, although FSG is a named
defendant, the third party and GeoStar would bear primary liability from this arbitration action.

Western Gas Resources, Lance Oil and
Gas Company, Inc. and Williams Production RMT Company vs. First Sourcenergy Wyoming, Inc. and First Sourcenergy Group, Inc.On May 3, 2005, FSW and FSG, both wholly owned Company subsidiaries, were party to a complaint concerning a June
2002 Lease Exchange and Purchase Agreement between certain of the parties. The issue involves a certain natural gas gathering agreement and its applicability to some of the properties exchanged under the June 2002 Agreement. A formal response to the
complaint was filed in June 2005. Discovery on this matter is currently underway and trial is scheduled to commence in September 2006. After evaluation of potential exposure and legal preparation and trial costs, the Company elected to settle this
matter by cash payment of $1.2 million. Settlement documents and payment are anticipated to be completed by the end of August 2006.

Navasota Resources L.P. vs. First Source Texas, Inc., First Source Gas L.P. and Gastar Exploration Ltd. (Cause No. 0-05-451) District Court of Leon County, Texas 12thJudicial District.This lawsuit 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 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 has filed an appeal of the summary judgment ruling. The Company intends to
continue to vigorously defend against this claim.

Gastar Exploration Texas L P vs. John E. McFarlane, et al (Cause No. 0-06-161)
87thJudicial District Court of Leon County, Texas.This
suit is one to quiet title to minerals under an oil and gas lease dated December 4, 2003 covering approximately 2,598 gross acres (Lease). John E. McFarlane, and certain other family members, contend that minerals subject to the
Estate of Fay Watson McFarlane are not subject to the Lease. The Company claims that said minerals are in fact subject to the Lease. The existence of unleased mineral interests in this Lease could adversely impact future development of the Lease.
The Company will continue to vigorously pursue this claim.

Burning Rock Energy, LLC, et al vs. First Sourcenergy Wyoming, Inc. (now Gastar Exploration USA,
Inc.), et al.Burning Rock contends in this 2006 lawsuit that Gastar and the operator of certain Wyoming properties were obligated under a January 1, 2004 Exchange Agreement to make lease maintenance payments on certain leases to be
assigned to Burning Rock under the Exchange Agreement. The case is in the discovery phase and the Company intends to vigorously defend against the claim.

Commitments

In March 2006, the Company entered into an agreement with a drilling contractor to provide contracted
drilling services in the Hilltop Area of East Texas for a three year period at agreed upon day rates. The Company made an initial payment of $1.0 million upon execution of the agreement and is required to make a second advance payment of $1.0
million upon rig delivery, which is anticipated prior to year end 2006. The advance payments will be amortized over the three-year term of the agreement. The Company is required to pay the drilling contractor a minimum of $6.3 million per year in
drilling day rate fees, net of the amortization of the advance payments, during the term of the agreement.

Future Share Issuances

Pursuant to the GeoStar Acquisition, GeoStar may receive additional common shares based on look-backs at June 30, 2006 and
June 30, 2007 on the East Texas assets, based on a required number of drilled wells, and net reserve additions valued at $1.50 per Mcf less attributable development expenditures to GeoStars acquired interest. The look-back calculations
are to be based on a third party engineering report and calculated within 60 days of receipt of the engineering report. Common shares to be issued, if any, are to be based on the five day weighted average trading price on the day preceding the
actual payment of shares, discounted by ten percent.

|(1) | In accordance with U.S. principles, the Company recognizes revenue and expenses on the statement of operations without regard to levels of commercial production and calculated and
reported depletion on the income statement. For Canadian principles, since the Company had not reached commercial levels of production, it was considered to be in the pre-production stage. While in the pre-production stage, the Company netted their
natural gas and oil revenue and lease operating expenses against natural gas and oil properties on the balance sheet and did not record depletion on their natural gas and oil properties. The Company was in the pre-production stage until
June 30, 2002.

|(2) | In accordance with U.S. principles, the amount of Convertible Senior Debentures is recognized as debt and is offset by the value attributable to the beneficial conversion feature.
The value of the warrants attached to debt as well as the value of the conversion feature of the convertible debt is recognized as paid-in capital in Shareholders Equity. The amortization of the beneficial conversion feature is amortized over
the term of the related convertible notes. For Canadian principles, these convertible notes are considered to be compound financial instruments and the liability component and the equity component must be presented separately as determined at
initial recognition.

determined by independent engineers. For Canadian principles, the Company adopted the new Canadian
guideline AcG-16 in 2003, in which a similar ceiling test calculation is performed with the exception that cash flows from proved reserves are undiscounted and utilize forecast pricing, based on sales prices achievable under existing contracts and
posted average reference prices in effect between the end of the year and the finalization of the year end audit and current costs to determine whether impairment exists. Any impairment amount is measured using the fair value of proved and probable
reserves. Unproved properties are tested separately for impairment.

In computing its consolidated net loss for US GAAP purposes, the
Company recorded a write down of properties in 2000, 2001, 2002, 2003, 2004, 2005 and 2006 as a result of the application of the US GAAP ceiling test. For Canadian principles, the Company recorded a write down in 2002 and 2003 only. Therefore,
the depletion base of unamortized capitalized costs is less for US GAAP purposes.

Effective January 1, 2004, the Canadian
Accounting Standards Board amended the Full Cost Accounting Guideline. Under Canadian GAAP, depletion charges are calculated by reference to proved reserves estimated using estimated future prices and costs. Under US GAAP, depletion
charges are calculated by reference to proved reserves estimated using constant prices.



|(5) | For U.S. principles, the value of the warrants is allocated based on relative fair values and is netted against the debt and is amortized as interest expense. For Canadian
principles, the fair value of the warrants are recorded as a deferred charge and amortized over the life of the note.

|(6) | In accordance with U.S. principles, debt discount is netted against the debt and not deferred as a financing cost. The debt discount is amortized as interest expense using the
interest method. For Canadian principles, the fair value of the debt discount is recorded as a deferred charge and amortized over the life of the note.

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

The following discussion and analysis should be read in conjunction with accompanying condensed consolidated financial statements and related notes included elsewhere in this Form 10-Q. It contains forward looking statements that reflect
our future plans, estimates, beliefs and expected performance. The forward looking statements are dependent upon events, risks and uncertainties that may be outside our control. Our actual results could differ materially from those discussed in
these forward looking statements. Factors that could cause or contribute to such differences include, but are not limited to, market prices for natural gas and oil, economic and competitive conditions, regulatory changes, estimates of proved
reserves, potential failure to achieve production from development projects, capital expenditures and other uncertainties, as well as those factors discussed below in this Form 10-Q and in our Annual Report on Form 10-K for the year ended
December 31, 2005, particularly in Risk Factors and Cautionary Notes Regarding Forward Looking Statements, all of which are difficult to predict. In light of these risks, uncertainties and assumptions, the forward
looking events discussed may not occur.

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. Our principal business activities include the identification,
acquisition, and subsequent exploration and development of natural gas and oil properties. Our emphasis is on prospective deep structures identified through seismic and other analytical techniques as well as unconventional natural gas reserves, such
as coal bed methane, or CBM. We currently are pursuing conventional natural gas exploration in the Deep Bossier play in the Hilltop area in East Texas and the Appalachian Basin in West Virginia. Our primary CBM properties are in the United States in
the Powder River Basin and in the Gunnedah and Gippsland Basins of Australia.

Recent Activities

Hilltop Area, East Texas

During the six months ended
June 30, 2006, we continued our exploratory drilling program in the Hilltop area of East Texas. In January 2006, we placed the Donelson #1 (100% working interest) and #2 (100% working interest) wells on production. The Donelson #1 is producing
from the lower Bossier formation, while the Donelson #2 was initially completed in the Knowles formation. In May 2006, the Donelson #2 was dually completed in the Pettet formation, significantly increasing the wells oil and natural gas and oil
production. In January 2006 drilling commenced on the Wildman Trust #1 (67% working interest) and the well was ultimately completed in the middle and upper Bossier formations in May 2006.

Also in May 2006, we added an additional rig in East Texas and commenced drilling the Wildman Trust #2 (56% before casing point, 67% after casing point
working interest) and the John Parker #1 (42% before casing point, 50% after casing point) wells. The Wildman Trust #2 well, located in the Hilltop area, is targeted to test the upper, middle and lower Bossier formations with a projected total depth
of approximately 19,200 feet. Total well depth is anticipated to be reached in September 2006. The John Parker #1 well is located on the northwestern portion of our leasehold position and is in a structural position projected to be similar to recent
successful wells drilled in close proximity by other operators. This well is targeted to test the middle Bossier formation with a projected total depth of approximately 17,500 feet. Total depth is anticipated to be reached in late August 2006.

Our operational plans for the deep Bossier play for the remainder of 2006 include the drilling of at least two additional deep Bossier
wells following the John Parker #1 and the Wildman Trust #2 wells and the possible addition of a third rig in the fourth quarter of 2006. We also are participating in a large scale 3-D seismic survey that will cover the majority of our acreage
position in the Hilltop area. The 3-D seismic data should be available for processing during the first quarter of 2007.

Sabine Island, Orange County,
Texas

In May 2006, we commenced drilling on the Odom #1well (33% before casing point, 25% after casing point working interest) located
in Orange County, Texas. This 3-D seismic based non-operated exploratory well is targeting the Yegua formation. The well is anticipated to reach the targeted depth during the third quarter of 2006.

PEL 238, Gunnedah Basin, New South Wales, Australia.

We have a 35% interest in PEL 238, a CBM property covering approximately 2.0 million gross acres (700,000 net acres), located in the Gunnedah Basin
of New South Wales approximately 250 miles northwest of Sydney, Australia. During the six months ended June 30, 2006, the operator drilled 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. The new wells will be perforated in the Bohena coal seam and then hydraulically fracture stimulated before being placed into test production during the fourth quarter. The closely spaced
nine-spot production pilot is designed to accelerate dewatering of the thick Bohena coal seam and to achieve commercial natural gas production rates in a shorter period than would be possible for an isolated well or for wells drilled on
wider spacing. A pressure monitoring well was drilled approximately 2.2 kilometers (1.4 miles) north of the existing wells in 2006 to assist in determining the extent of in-seam permeability communication in the Bohena coal seam.

EL 4416, Gippsland Basin, Victoria, Australia

We
have a 75% interest in the CBM rights in EL 4416, an approximate 1.0 million gross acre property (750,000 net acres), covering a substantial portion of the onshore Gippsland Basin. The property is located east of Melbourne in the State of
Victoria, Australia. During the second quarter of 2006 we began initial long-term testing of the first of two wells completed on EL 4416. Early water production has been significant, indicating permeability in the targeted coal seam. Current plans
are to increase the downhole pump capacity to accelerate the dewatering process. Drilling of additional wells is anticipated to commence by early 2007 to evaluate the viability of commercial CBM production from this property.

Results of Operations

The following is a comparative
discussion of the results of operations for the three and six months ended June 30, 2006 and 2005. It should be read in conjunction with the condensed consolidated financial statements and the related notes and other information included
elsewhere in this Form 10-Q.

Three Months Ended June 30, 2006 Compared to the Three Months Ended June 30, 2005.

Net loss. We reported a net loss attributable to common shares for the three months ended June 30, 2006 of $6.7 million, compared to a net
loss of $8.7 million for the three months ended June 30, 2005. The net loss for 2006 includes a litigation settlement expense of $1.2 million. The net loss for 2005 includes an impairment of natural gas and oil properties of $4.3 million.

Revenues. Substantially all of our revenues are derived from the production of natural gas in the United States. We reported
revenues of $6.7 million for the three months ended June 30, 2006, up from $4.9 million for the comparable period in 2005. The 35% increase in revenues was primarily attributable to a 58% increase in production resulting from the June 2005
GeoStar Acquisition, commencement of production of natural gas from several new wells in East Texas in 2005 and 2006 and an increase, effective June 1, 2006, in our Wyoming properties net revenue interest as a result of a joint venture payout.
The increase in production was partially offset by a 15% decline in natural gas prices.

Lease operating, transportation and selling. We reported expenses for lease operating,
transportation and selling of $2.1 million for the three months ended June 30, 2006, up from $477,000 for the comparable period in 2005. This increase was attributable to higher production volumes and the inclusion of a severance tax refund
benefit in 2005 of $350,000. Our lease operating expense per Mcfe increased to $1.77 per Mcfe during the three months ended June 30, 2006 from $1.09 per Mcfe for the comparable period in 2005, excluding the 2005 severance tax refund benefit.
The increase in per Mcfe cost primarily was the result of additional fixed costs associated with natural gas treatment plants in East Texas and an increase in the number of producing wells.

Depletion, depreciation and amortization.We reported depletion, depreciation and amortization (DD&A) of $3.6 million for the
three months ended June 30, 2006, up from $2.3 million for the comparable period in 2005. The DD&A increase primarily due to higher production volumes. The DD&A rate for the three months ended June 30, 2006 was $2.97 per Mcfe,
compared $2.99 per Mcfe for the three months ended June 30, 2005.

Impairment of natural gas and oil properties.The weighted
average natural gas price utilized for the June 30, 2006 ceiling impairment evaluation was $6.60 per Mcf, held constant, and resulted in a ceiling cushion of natural gas and oil properties of $26.7 million. For the three months ended
June 30, 2005, we reported a $4.3 million impairment of natural gas and oil properties, primarily as a result of lower natural gas prices. The impairment of natural gas and oil properties for the three months ended June 30, 2005 was based
on a weighted average natural gas price of $5.32 per Mcf, held constant.

Interest and debt related items.We reported interest
expense of $3.8 million for the three months ended June 30, 2006, down from $5.0 million for the comparable period in 2005. In June 2005, as a condition to the issuance of the senior secured notes, the 15% senior notes were called and repaid in
full resulting in 2005 interest expense including a call premium of $662,000 and expensing of unamortized deferred costs of $630,000.

General and administrative expenses. We reported general and administrative expenses of $3.1 million for the three months ended June 30, 2006, up from $1.8 million for the comparable period in 2005. The increase in general and
administrative expenses was primarily due to a higher level of permanent and contract staff and professional service charges. Included in current quarter general and administrative expenses is approximately $345,000 of professional fees related to
the proposed Gippsland Basin Victoria, Australia brown coal acquisition that was ultimately canceled.

Investment income and other.
We reported $492,000 in investment income and other for the three months ended June 30, 2006, up from $22,000 for the comparable period in 2005. This increase was due to investment income earned on the cash balances from the proceeds received
as a result of the issuance of common shares in November 2005.

Litigation settlement expense.Represents 2006 settlement cost to be
incurred in conjunction with the Western Gas Resources, et al litigation matter.

Six Months Ended June 30, 2006 Compared to the Six Months Ended June 30, 2005.

Net loss. We reported a net loss attributable to common shares for the six months ended June 30, 2006 of $49.6 million,
compared to a net loss of $16.3 million for the six months ended June 30, 2005. The net losses for 2006 and 2005 include impairment of natural gas and oil properties of $37.3 million and $8.7 million, respectively. The net loss for 2006 also
includes a litigation settlement expense of $1.2 million.

Revenues. Substantially all of our revenues are derived from the
production of natural gas in the United States. We reported revenues of $13.3 million for the six months ended June 30, 2006, up from $9.7 million for the comparable period in 2005. The increase in revenues was primarily attributable to a 36%
increase in production resulting from the June 2005 GeoStar Acquisition, the commencement of production of natural gas from new wells in East Texas in 2005 and 2006 and an increase in Wyoming production from new CBM wells drilled in the Powder River
Basin and effective June 1, 2006 an increase in the companys Wyoming net revenue interest as a result of a joint venture payout. Of the increase in revenues, 96% was attributed to higher production rates and 4% resulted from natural gas
and oil price increases.

Natural Gas and Oil Production and Average Sales Prices. Natural gas represents substantially all of our

Lease operating, transportation and selling. We reported expenses for lease operating,
transportation and selling of $4.1 million for the six months ended June 30, 2006, up from $1.8 million for the comparable period in 2005. This increase was attributable to higher production volumes and the inclusion of a severance tax refund
benefit in 2005 of $350,000. Our lease operating expense per Mcfe increased to $1.86 per Mcfe during the first six months of 2006, up from $1.33 per Mcfe for the comparable period in 2005, excluding the severance tax refund benefit. The increase in
per Mcfe cost primarily was the result of additional fixed costs associated with natural gas treatment plants in East Texas and an increase in the number of producing wells.

Depletion, depreciation and amortization.We reported depletion, depreciation and amortization (DD&A) of $7.9 million for the six
months ended June 30, 2006, up from $5.0 million for the comparable period in 2004. DD&A increased primarily due to higher production rates and a higher DD&A rate per unit. Of the increase in DD&A expense, 61% was attributed to
higher production rates and 39% was due to an increase in DD&A rate per unit. The DD&A rate for the six months ended June 30, 2006 was $3.59 per Mcfe, compared $3.08 per Mcfe for the six months ended June 30, 2005.

Impairment of natural gas and oil properties.We reported a non-cash ceiling test impairment of natural gas and oil properties for the six months
ended June 30, 2006 of $37.3 million, up from the $8.7 million reported for the comparable period in 2005. The impairment was the result of a decline in natural gas prices from year end 2005, together with limited first quarter drilling results
in East Texas and the related lag in reserve recognition. At March 31, 2006, the weighted average natural gas price utilized for ceiling impairment was $5.79 per Mcf, held constant, a 22% decline from year end 2005 comparable price of $7.39 per
Mcf. The weighted average natural gas price utilized for the June 30, 2006 ceiling impairment evaluation was $6.60 per Mcf, held constant, and resulted in a ceiling cushion of natural gas and oil properties of $26.7 million. The impairment of
natural gas and oil properties for the six months ended June 30, 2005 of $8.7 million was based on a weighted average natural gas price of $5.32 per Mcf, held constant.

Interest and debt related items.We reported interest expense of $7.6 million for the six months
ended June 30, 2006, up from $7.1 million for the comparable period in 2005. This increase was due to an increase in debt outstanding as a result of the issuance of $73.0 million of senior secured notes in June and December 2005, which was
partially offset by the repayment of $25.0 million senior notes in June 2005. In June 2005, as a condition to the issuance of the senior secured notes, the 15% senior notes were called and repaid in full resulting in 2005 interest expense including
a call premium of $662,000 and expensing of unamortized deferred costs of $667,000.

General and administrative expenses. We
reported general and administrative expenses of $5.6 million for the six months ended June 30, 2006, up from $3.5 million for the comparable period in 2005. The increase in general and administrative expenses was primarily due to a higher level
of permanent and contract staff and professional service charges. Included in the six months ended June 30, 2006 general and administrative expenses is approximately $345,000 of professional fees related to the proposed Gippsland Basin
Victoria, Australia brown coal acquisition that was ultimately canceled.

Investment income and other. We reported $1.0 million in
investment income and other for the six months ended June 30, 2006, up from $62,000 for the comparable period in 2005. This increase was due to investment income earned on the cash balances from the proceeds received as a result of the issuance
of common shares in November 2005.

Litigation settlement expense.Represents 2006 settlement cost to be incurred in conjunction
with the Western Gas Resources, et al litigation matter.

Liquidity and Capital Resources

For the six months ended June 30, 2006, we reported positive cash flow from operations of $8.4 million. Capital expenditures on natural gas and oil
properties totaled $26.4 million during the period. At June 30, 2006, approximately $38.9 million remained in available cash and cash equivalents for future capital expenditures as well as other corporate purposes.

Pursuant to the terms of our senior secured notes, we have the right, exercisable quarterly to June 16, 2007, to require the original purchasers of
the senior secured notes to purchase additional notes in an amount limited to an aggregate of $10.0 million in principal, provided that we comply with proved plus probable reserve present value discounted at 10%, or PV(10), to net senior secured
debt coverage ratio of 2.0:1 and other general covenants and conditions. The PV(10) value is to be based on a third party independent reserve report utilizing constant pricing based on the lower of current natural gas and oil prices, adjusted for
area basis differentials, or $6.00 per Mcf of natural gas and $40.00 per barrel of oil. Utilizing the same reserve pricing criteria above, the proved plus probable reserves PV(10) (2P PV(10)) to net senior secured notes debt reserve
maintenance ratio covenant must be a minimum of 1.5:1 from date of issuance of the notes up to the day immediately preceding the first anniversary date. On the first anniversary date of the senior secured notes, the 2P PV(10) reserve ratio
maintenance covenant increased to a minimum of 2.5:1 and will increase on the second anniversary to 3.0:1 and on the third anniversary and for all test periods thereafter until maturity to 3.5:1. Utilizing the same reserve pricing criteria above,
the proved reserves PV(10) (1P PV(10)) to net senior secured notes debt reserve maintenance ratio covenant must be a minimum of 1.0:1 from date of issuance of the notes up to the day immediately preceding the second anniversary date. On
the second anniversary date of the senior secured notes, the 1P PV(10) reserve ratio maintenance covenant increases to a minimum of 1.5:1 and on the third anniversary and for all test periods thereafter until maturity to 2.0:1. We must maintain
compliance with the reserve ratio covenants at all future quarterly and annual covenant determination dates or be subject to mandatory principal redemptions under certain conditions. The senior secured notes prohibit us from issuing any debt senior
or pari passu to the senior secured notes and may limit our ability to borrow subordinated funds and payment of dividends.

We
continually evaluate our capital needs and compare them to our capital resources. To execute our operational plans, particularly our drilling plans in East Texas, 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, the issuance of additional senior secured notes or the issuance of additional
equity. We may also attempt to balance future capital expenditures through joint venture development of certain properties with industry partners. We are in the early stages of exploration and development of our East Texas properties. Amounts and
timing of future cash flows is dependent on confirmation of production from recently completed wells, together with the success of currently drilling and future wells to be drilled. We cannot be certain that future funds will be available to fully
execute our current business plan.

Our capital expenditures in the next 12 months under our current business plan are estimated to total
approximately $79.0 million, of which $68.3 million is estimated to be spent on conventional natural gas and oil exploration and development operations, $4.5 million is estimated to be spent on CBM projects in the United States and $6.2 million is
estimated to be spent on CBM projects in Australia. Given the forecast for natural gas and oil prices, cash on hand and projected production volume increases, we believe that approximately $30 million of additional financing will be necessary to
execute our business and operational plans over the next 12 months. The additional financing funds will most likely include the issuance of additional equity and additional senior secured notes.

We 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 senior secured notes, resulting in mandatory principal reduction under certain conditions.

We currently have no natural gas price financial instruments or hedges in place. Our natural gas marketing contracts use spot market prices.
We may enter into long-term fixed-price natural gas contracts, swap or hedge positions, other gas financial instruments or financial derivatives later in 2006. A senior secured notes covenant restricts us from hedging more than 50% of future
production.

As of June 30, 2006, we were in compliance with all debt covenants.

Off-Balance Sheet Arrangements

As of June 30,
2006, 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 principles generally accepted
in the United States of America 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 our Annual Report of Form 10-K for the year ended December 31, 2005.

Item 3.Quantitative and Qualitative Disclosure about Market Risk

Commodity 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. For the six months ended June 30, 2006, a 10% change in
the prices received for natural gas production would have had an approximate $1.3 million impact on our revenues. To date, we have not entered into hedge transactions to mitigate our commodity pricing risk.

Interest Rate Risk

The carrying value of our
debt approximates fair value. At June 30, 2006, we had approximately $106.3 million in principal amount of long-term debt of which $73.0 million of the senior secured notes was subject to a floating interest rate of LIBOR plus 6%. Our
convertible senior debentures and subordinated unsecured notes payable are fixed debt rate, but the interest rates are not materially different than current prevailing market rates and, as such, their carrying value approximates fair value. A 10%
fluctuation in interest rates would have an approximate $838,000 impact on annual interest expense.

Currency Translation Risk

Because our revenues and expenses are primarily in U.S. dollars, we have little exposure to currency translation risk, and, therefore, 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 Conclusion on the Effectiveness of Disclosure Controls
and Procedures

Our Chief Executive Officer and the Chief Financial Officer performed an evaluation of our disclosure controls and
procedures. As defined in Exchange Act Rule 13a-15(e) and 15d-15(e), disclosure controls and procedures are designed to ensure that information required to be disclosed by us in reports we file or submit under the Exchange Act is recorded,
processed, summarized and reported within the time periods specified in the SECs rules and forms. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that the Companys disclosure controls and
procedures were effective as of June 30, 2006 at a reasonable assurance level. While our disclosure controls and procedures provide reasonable assurance that the appropriate information will be available on timely basis, this assurance is
subject to limitations inherent in any control system, no matter how well it may be designed or administered.

Changes in Internal Control over
Financial Reporting

There was no change in our internal control over financial reporting during the quarter ended June 30, 2006,
that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
