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 nine months ended September 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 effective 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
September 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. On September 19, 2006,
the twelve-month anniversary of the September 19, 2005 $10.0 million Senior Secured Notes issuance, the Company issued to the note holders an additional 256,016 common shares at CDN$2.79 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. 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 volume weighted average trading
price of the common shares of the Company, for at least 20 trading days in any consecutive 30-day period, equals or exceeds $5.69.

Subordinated
Unsecured Notes Payable

In July 2004, the Company completed a $3.25 million subordinated unsecured note financing (Unsecured
Notes). The Unsecured Notes mature between April 2009 and September 2009, bear interest at 10% per annum and are callable by the Company after two years at 108% of the principal amount. The call premium reduces to 105% after three years
and to a 101% after four years.

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 two, three or four-year period at 50%, 33% or 25% per year. Once exercisable, the
employee may purchase common shares of the Company at the market price on the date the stock option was granted. New common shares are issued upon exercise of stock options.

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 stock options granted will be determined by the Board of Directors at the time stock options are granted. As of September 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 resulting in a 6.5-year expected life 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 initial
compensation expense.

Share Based Compensation

For the three months ended September 30, 2006 and 2005, the Company recorded $1.4 million and $524,000, respectively, in stock-based compensation
expense for stock options granted using the fair-value method and $3,000 for director meeting fees waived during the three months ended September 30, 2006. For the nine months ended September 30, 2006 and 2005, the Company recorded $2.6
million and $2.1 million, respectively, in stock-based compensation expense for stock options granted using the fair-value method and $10,500 for director meeting fees waived during the first nine months of 2006. All stock based compensation costs
were expensed and not tax effected as the Company currently records no tax expense.

At September 30, 2006, the Company had unvested
stock options to purchase 7,834,500 common shares with a weighted average grant date fair value of $1.25. As of September 30, 2006, the Company had approximately $6.4 million of total unrecognized compensation cost related to unvested stock
options, which is expected to be amortized over the following 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.

11. Warrants

In February 2006, the Company issued 21,948 common shares upon exercise of warrants related to the Convertible Senior Debentures. In May 2006, the remaining 237,792 of Convertible Subordinated Debentures warrants
expired, resulting in total warrants outstanding at September 30, 2006 of 2,732,521.

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 their position is sound and intend 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 involved 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. After evaluation of potential exposure and legal preparation and trial costs, the Company elected to settle this matter by cash payment of $1.7 million. Settlement documents and payment were completed in September
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 itself against this claim.

Gastar Exploration Texas LP 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 itself against the claim.

GeoStar Arbitration Request. On October 18, 2006, in connection with ten wells to be drilled in Victoria, Australia on the jointly owned EL 4416 license, operated by GeoStar Corporation, Gastar sent a
letter to GeoStar demanding the arbitration of certain disputed issues and interpretations under a Participation and Operating Agreement (POA) with GeoStar and its subsidiaries. Among other items, Gastar presented for resolution in
arbitration are: GeoStars failure to deliver certain documents to Gastar and GeoStars demands for cash calls under the POA while simultaneously asserting that certain provisions of the POA, including overhead reimbursement rates, need to
be renegotiated on terms that Gastar believes are not reasonable and within industry standards. Gastar has requested an expedited hearing and is waiting for the scheduling of the hearing. Our former Chairman of the Board is President and a major
shareholder of GeoStar.

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 December 31, 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 Gastar common shares or forfeit Gastar common shares held by GeoStar 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 Gastars third party engineering report of proven and probable
reserves and calculated within 60 days of receipt of the engineering report. Pursuant to the purchase and sale agreement, GeoStar has elected, at their sole cost, to retain an independent, professionally certified reservoir engineering firm to
independently prepare a proven and probable engineering report on the East Texas assets utilizing existing Securities and Exchange Commission and Society of Professional Engineers reserve calculation guidelines. If the GeoStar engineering report
determines that the East Texas reserves are greater than Gastars engineering report, the average of the Gastar and GeoStar engineering report reserves will be utilized for the look-back calculation. Common shares to be issued or forfeited, 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. Based on Gastars look-back analysis at June 30, 2006, no additional Gastar Common shares
were due to GeoStar. Gastar is still awaiting confirmation of GeoStars June 30, 2006 engineering report and look-back analysis to support that conclusion.

|(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.

future net operating revenue from proved reserves plus unimpaired unproved property costs less future
development costs, related production costs, abandonment and reclamation costs and applicable taxes, as 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.

15. Subsequent Event  Private Placement of Common Shares

On November 14, 2006, the Company announced that it had priced a private placement of 25,000,000 of its common shares at $2.00 per share. The shares were sold to institutional accredited investors in the United
States, including Chesapeake Energy Corporation. The private placement is expected to close on or about November 17, 2006, subject to receipt of applicable regulatory approvals, as well as the satisfaction of other customary closing conditions.
Net proceeds from this placement, estimated at $47.9 million, after deducting placement fees and estimated expenses, will be used to fund the Companys drilling programs and for general corporate purposes.

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 nine months ended
September 30, 2006, we continued our exploratory drilling program in the Hilltop area of East Texas. In January 2006, we placed the Donelson #1 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 natural gas and oil production. In April
2006, we completed drilling of the Wildman Trust #1 (67% working interest), and the well was ultimately completed in the middle and upper Bossier formations in May 2006.

In May 2006, we increased the number of drilling rigs in the Hilltop area to two 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 was drilled to a depth of approximately 19,500 feet and log analysis showed prospective zones in the middle and lower Bossier formations. To date, we have tested
three lower Bossier formations with one of the zones capable of producing natural gas. Middle Bossier completion operations have been delayed due to two mechanical problems with the well. A component on the surface wellhead equipment partially
failed and has now been repaired. In addition, coiled tubing, being used to clean the well bore prior to fracture stimulation, was stuck and will need to be removed before completion operations can continue. The coiled tubing problem was caused by
strong gas flows prior to fracture stimulation from the middle Bossier formation. The well is expected to be fracture stimulated in the first middle Bossier sand and capable of gas sales by December 2006. The John Parker #1 well located on the
northwestern portion of our leasehold position was drilled to a depth of approximately 17,500 feet, and log analysis indicated potential pay zones in four middle Bossier sands. The well was successfully completed in two middle Bossier zones, and we
are planning to fracture stimulate one additional middle Bossier sand in November 2006 and return the well to production.

In the third
quarter, we commenced drilling the John Parker #2 (42% before casing point, 50% after casing point working interest) and the Williams #1 (56 before casing point, 67% after casing point). The John Parker #2, an offset to the John Parker #1, is
targeted to test the middle Bossier formation with a projected total

depth of approximately 18,000 feet. The Williams #1, an offset to the Wildman Trust #2 well, is targeting prospective
middle and lower Bossier sands. Total depth on both wells is anticipated to be reached in December 2006. We anticipate adding a third drilling rig by mid-November to expedite our Bossier drilling activity. The new rig will be under a three year
contract and will initially be utilized to drill middle Bossier exploration and development wells in the Hilltop area.

We plan to continue
an active drilling program into 2007 and beyond to further evaluate and develop our Deep Bossier assets. We are also 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.
Due to well bore problems, the well was unable to reach targeted depth and was abandoned. The operator currently plans to redrill this 3-D seismic-based Yegua exploratory well in 2007. Our share of drilling costs in this well was approximately $5.0
million.

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 nine months ended September 30, 2006, the operator completed the drilling of nine 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 have been successfully perforated and hydraulically fracture stimulated in the Bohena coal seam. The wells are currently being completed and will be placed into test
production by year end. 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. Before pump
failure, early water production had been significant, indicating permeability in the targeted coal seam. A ten well drilling program is scheduled to commence late fourth quarter 2006, for which we have committed $6.5 million, will include the
establishment of two 5-spot pilots, one incorporating the two existing wells, and two wells designed to test for the presence and production potential of the coals at additional locations within the license area. The two previously
drilled wells are also scheduled to have larger capacity pumps installed to facilitate de-watering operations.

Results of Operations

The following is a comparative discussion of the results of operations for the three and nine months ended September 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 September 30, 2006 Compared to the Three Months Ended September 30, 2005.

Net
loss. We reported a net loss attributable to common shares for the three months ended September 30, 2006 of $7.7 million, compared to a net loss of $4.6 million for the three months ended September 30, 2005.

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 September 30, 2006, down from $7.8 million for the comparable period in 2005. The 15% decrease in revenues was primarily attributable to a 34% decrease in natural
gas prices. The decrease in price was partially offset by a 25% increase in production resulting from the commencement of production of natural gas and oil from several new wells in East Texas in 2005 and 2006 and an increase, effective June 1,
2006, in our net revenue interest as a result of a joint venture payout on our Wyoming properties.

Natural Gas and Oil Production and
Average Sales Prices. Natural gas represents substantially all of our production. The table below sets forth production and sales information for the periods indicated:

Lease operating, transportation and selling. We reported expenses for lease operating,
transportation and selling of $2.5 million for the three months ended September 30, 2006, up from $2.2 million for the comparable period in 2005. This increase was attributable to higher production volumes. Our lease operating expense per Mcfe
decreased to $2.01 per Mcfe during the three months ended September 30, 2006 from $2.21 per Mcfe for the comparable period in 2005. The decrease in per Mcfe cost primarily was the result of the fixed costs associated with natural gas treatment
plants in East Texas being allocated over higher production volumes.

Depletion, depreciation and amortization.We reported
depletion, depreciation and amortization (DD&A) of $3.6 million for the three months ended September 30, 2006, down from $4.1 million for the comparable period in 2005. The DD&A decrease is primarily due to higher reserve
amounts at September 30, 2006. The DD&A rate for the three months ended September 30, 2006 was $2.88 per Mcfe, compared to $4.05 per Mcfe for the three months ended September 30, 2005.

Impairment of natural gas and oil properties.We did not record an impairment of natural gas and oil properties for the three months ended
September 30, 2006 or 2005. The weighted average natural gas price utilized for the September 30, 2006 ceiling impairment evaluation was $5.52 per Mcf, held constant, resulting in a ceiling cushion of natural gas and oil properties of
$24.4 million.

Interest and debt related items.We reported interest expense of $4.0 million for the three months ended
September 30, 2006, up from $3.6 million for the comparable period in 2005. The increase is primarily due to additional debt discount amortization and higher effective interest rate on the Senior Secured Notes.

General and administrative expenses. We reported general and administrative expenses of $2.7 million for the three months ended September 30,
2006, up from $1.9 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.

Stock option expense. We reported stock option expense of $1.4 million for the three months ended September 30, 2006 up from $524,000 for the
comparable period in 2005. The increase was primarily due the additional stock option grants in 2006.

Investment income and other. We reported $372,000 in investment income and other for the three
months ended September 30, 2006, up from $25,000 for the comparable period in 2005. This increase was primarily 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.The $465,000 litigation settlement expense incurred in 2006 was in conjunction with
the Western Gas Resources, et al, final settlement payment made in September 2006.

Nine Months Ended September 30, 2006 Compared to the
Nine Months Ended September 30, 2005.

Net loss. We reported a net loss attributable to common shares for the nine
months ended September 30, 2006 of $57.3 million, compared to a net loss of $20.9 million for the nine months ended September 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 $1.7 million.

Revenues. We
reported revenues of $20.0 million for the nine months ended September 30, 2006, up from $17.5 million for the comparable period in 2005. The increase in revenues was primarily attributable to a 32% increase in production resulting from the
September 2005 GeoStar Acquisition, the commencement of production of natural gas from new wells in East Texas in 2005 and 2006, an increase in Wyoming production from new CBM wells drilled in the Powder River Basin and an increase in our Wyoming
net revenue interest as a result of a joint venture payout effective June 1, 2006. The increase in natural gas and oil production was partially offset by a 15% decrease in natural gas prices.

Natural Gas and Oil Production and Average Sales Prices. Natural gas represents substantially all of our production. The table below sets forth
production and sales information for the periods indicated:

Lease operating, transportation and selling. We reported expenses for lease operating,
transportation and selling of $6.6 million for the nine months ended September 30, 2006, up from $4.0 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 $1.92 per Mcfe during the first nine months of 2006, up from $1.67 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 DD&A of $11.5 million for the nine months ended September 30, 2006, up from $9.1
million for the comparable period in 2005. DD&A increased primarily due to higher production rates, which was partially offset by a 3% reduction in DD&A rate per unit. The DD&A rate for the nine months ended September 30, 2006 was
$3.33 per Mcfe, compared $3.45 per Mcfe for the nine months ended September 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 nine months ended September 30, 2006 of $37.3 million, up from the $8.7 million reported for the comparable period in 2005. The 2006
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 September 30, 2006 ceiling impairment evaluation was $5.52 per Mcf, held constant, and resulted in a ceiling cushion of natural gas and oil properties of $24.4 million. The impairment of natural gas and oil properties for the
nine months ended September 30, 2005 of $8.7 million was based on weighted average natural gas prices of $5.32 per Mcf at June 30, 2005, held constant.

General and administrative expenses. We reported general and administrative expenses of $7.0 million for the nine months ended September 30, 2006, up from $3.9 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 nine months ended September 30, 2006 general and administrative expenses
is approximately $345,000 of professional fees related to the proposed Gippsland Basin Victoria, Australia brown coal investment that was ultimately canceled.

Stock option expense. We reported stock option expense of $2.6 million for the nine months ended September 30, 2006 up from $2.1 million for the comparable period in 2005. The increase was primarily due to
the additional stock option grants in 2006.

Interest and debt related items.We reported interest expense of $11.6 million for the
nine months ended September 30, 2006, up from $10.7 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 September and
December 2005, which was partially offset by the repayment of $25.0 million senior notes in September 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.

Investment income
and other. We reported $1.4 million in investment income and other for the nine months ended September 30, 2006, up from $87,000 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.The $1.7
million litigation settlement expense incurred in 2006 was in conjunction with the Western Gas Resources, et al, final settlement payment made in September 2006.

Liquidity and Capital Resources

For the nine months ended September 30, 2006, we reported
positive cash flow from operations of $9.0 million. Capital expenditures on natural gas and oil properties totaled $46.4 million during the period. At September 30, 2006, approximately $21.3 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 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 during
the period beginning on June 17, 2006 until June 17, 2007. On June 17, 2007, the 1P PV(10) reserve ratio maintenance covenant increases to a minimum of 1.5:1 and on June 17, 2008 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 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, 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 $97.3 million, of which $78.8 million
is estimated to be spent on conventional natural gas and oil exploration and development operations, $7.0 million is estimated to be spent on CBM projects in the United States and $11.5 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 $50 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. If we can not obtain these funds in capital market transactions, loans or otherwise, we may have to revise
our business plan and reduce our capital drilling program.

On November 14, 2006, the Company announced that it had priced a private
placement of 25,000,000 of its common shares at $2.00 per share. The shares were sold to institutional accredited investors in the United States, including Chesapeake Energy Corporation. The private placement is expected to close on or about
November 17, 2006, subject to receipt of applicable regulatory approvals, as well as the satisfaction of other customary closing conditions. Net proceeds from this placement, estimated at $47.9 million, after deducting placement fees and
estimated expenses, will be used to fund the Companys drilling programs and for general corporate purposes.

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
September 30, 2006, we were in compliance with all debt covenants.

Off-Balance Sheet Arrangements

As of September 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



24

##### Table of Contents

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 nine months ended September 30, 2006, a 10%
change in the prices received for natural gas production would have had an approximate $2.0 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 September 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 rate debt, 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 $830,000 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 September 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.
