PART I



|Item 1. | Business
|------- | --------

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 additional unconventional natural gas exploration in the deep Bossier
play in the Hilltop area in East Texas. Our primary CBM properties are in the Powder River Basin in Wyoming and in the Gunnedah and Gippsland Basins of Australia. Gastar Exploration Ltd. is a Canadian corporation that is subsisting under the
Business Corporations Act (Alberta).

Our Strategy

Management believes that:



| |  |  | Natural gas is an environmentally friendly fuel that will be increasingly valued in the United States and Australia;
| | - |  | --------------------------------------------------------------------------------------------------------------------



| |  |  | CBM projects provide us with lower risk exposure to long-lived natural gas production and reserves;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | We have confirmed a sizeable natural gas discovery in the deep Bossier play in the Hilltop area of East Texas that will require continued exploration and
development to fully define and exploit;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We have the ability to assemble the technical and commercial resources needed to pursue these projects; and
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | Our successful development of one or more large potential natural gas projects will create substantial asset and shareholder value.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------

Based on these beliefs, we have pursued a strategy that includes:



| |  |  | Accelerating seismic activities and exploration and development drilling on our deep Bossier play in East Texas;
| | - |  | ----------------------------------------------------------------------------------------------------------------



| |  |  | Combining lower risk CBM projects with higher risk unconventional natural gas exploration; and
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | Reducing risk by maintaining financial flexibility through accessing various sources of capital and participating in certain assets through joint venture
arrangements with industry participants thus limiting our capital commitments.

Natural Gas and Oil Activities

The following provides an overview of our major natural gas and oil projects.
While actively pursuing specific exploration and development activities in each of the following areas, we continue to review other opportunities. There is no assurance that new drilling opportunities will be identified or that any new drilling
opportunities will be successful if drilled.

Hilltop Area, East Texas

The majority of our activity focus has been in the deep Bossier play in the Hilltop area, located in East Texas approximately midway between Dallas and
Houston in Leon and Robertson Counties, Texas. This area is an emerging unconventional play and has attracted some of the largest and most active operators in the U.S. Wells in this area target multiple potentially productive natural gas geologic
horizons and are typically characterized by high initial production, significant decline rates and long-lived reserves. We have accumulated 51,975 gross (26,374 net) acres in the Bossier play. Our first successful well was spudded in 2003 and placed
on production in September 2004. During 2004 and 2005, we drilled an additional 6 gross (5.5 net) wells in the Hilltop area. During 2006, we continued our exploratory drilling program in the Hilltop area by drilling an additional 4 gross (2.3 net)
wells. In May 2006, we increased the number of drilling rigs in the Hilltop area to two rigs, and in November 2006, we added a third drilling rig under a three year contract to expedite our Bossier drilling activity. As of December 31, 2006, we
had successfully completed 10 of 11 deep Bossier wells. For the year ended December 31, 2006, our net production from the Hilltop area averaged approximately 7.9 MMcfed.

We are participating in a 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 early in the second quarter of 2007 and available for interpretation later that quarter. We currently have plans to drill an additional eight deep Bossier wells during 2007.

Coalbed MethanePowder River Basin, Wyoming

We own an approximate 40% average working interest in 54,966 gross (21,854 net) acres in the Powder River Basin of Wyoming. The Powder River Basin has been an important natural gas and oil producing area for nearly 100 years. Generally, CBM
wells are shallow and less costly than conventional natural gas wells. Our primary areas of activity in the Powder River Basin are Squaw Creek, Ring of Fire and adjacent fields, all of which are located north of Gillette, Wyoming in an active
drilling area.

During 2006, we participated in the drilling of approximately 43 (19.5 net) wells. Based on our third party reservoir
engineering report at December 31, 2006, we had an interest in 258 gross (104.7 net) economic CBM wells producing in the Basin. For the year ended December 31, 2006, our average net production from our CBM properties in the Powder River
Basin was approximately 4.8 MMcfed. We anticipate continuing an active recompletion and drilling program in 2007.

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

We have a 35% interest in PEL 238, a CBM exploratory property covering approximately
2.0 million gross (700,000 net) acres, located in the Gunnedah Basin of New South Wales, approximately 250 miles northwest of Sydney, Australia, near the town of Narrabri. We believe that the strategic location of these potential CBM reserves
near the large natural gas markets in Sydney-Newcastle-Wollongong area, and the concessions location relative to other developing gas markets should create a competitive advantage for the natural gas reserves that may be developed on PEL 238.

Extensive coring of the coal on PEL 238 by the Australian government has provided a thorough understanding of the coal resources and
potential CBM resource in place on our license. Two primary coal seams are found on the PEL 238 license, the Late Permian aged Hoskisson coal formation and the Early Permian aged Maules Creek coal formation.

During 2006, we participated with our joint venture partners in the drilling of eight new vertical coal
seam natural gas wells on approximately 40-acre spacing in close proximity to an existing well within the Bohena Project Area. The new wells have been successfully completed, and the pilot program wells were placed into test production in late 2006.
The closely spaced nine-spot production pilot is designed to accelerate dewatering of the Bohena coal seam and to achieve commercial natural gas production rates in a shorter time period than would be possible for an isolated well or for
wells drilled on wider spacing. The early results from the pilot production phase of the program have been positive, with the results confirming the high measured permeability of the coal and the presence of natural gas in the coal. If sustained
commercial natural gas production rates are achieved, we and our joint venture partners will proceed with development of the CBM resources. Our current pilot program will evaluate the commercialization of the Gunnedah Basin CBM project, with a
target to achieve initial certified natural gas reserves by the end of 2007.

In March 2007, we announced that we and our joint venture
partner had executed a Memorandum of Understanding with Macquarie Generation, a NSW Government-owned electricity generator, for the potential future supply of natural gas for the expansion of its Bayswater power station. Macquarie Generation is
Australias largest electricity producer and owns and operates two coal fired power stations in the Hunter ValleyBayswater and Liddell. A potential long-term natural gas supply and purchase agreement could reach as much as 500 billion
cubic feet in total and increase NSWs natural gas consumption by as much as 25%.

The area on which PEL 238 is located is subject to
native title claims; however, no such claims have been lodged at this time.

Coalbed MethaneEL 4416, Gippsland Basin, Victoria, Australia

We have a 75% interest in the CBM rights in EL 4416, an approximate 1.0 million gross (750,000 net) acre property covering a
substantial part of the onshore portion of the Gippsland Basin of Victoria, Australia, located approximately 130 miles east of Melbourne. The EL 4416 property is well situated with three existing natural gas transmission lines running through the
license area from productive offshore fields to a large natural gas processing facility and then to markets near Sydney, Melbourne and in Tasmania. The EL 4416 coal is classified as low-rank brown coal. The Victorian government has extensively
evaluated the potential coal resources through detailed coal resource studies. Due to our large acreage position and the fact that this thick coal is present over a large percentage of the license area, the CBM resource potential is believed to be
significant.

During 2006, we began initial long-term testing of the first of two wells completed on EL 4416. Before a pump failure, early
water production had been significant, indicating permeability in the targeted coal seam. We have pre-funded $6.5 million for a 10-well drilling program, which commenced late fourth quarter 2006. The program includes the establishment of two
5-spot pilots, one incorporating two existing wells and two wells designed to test for the presence and production potential of the coal at additional locations within the license area. In one of the two previously drilled wells, we have
installed larger capacity pumps to facilitate de-watering operations.

Our activities on EL 4416 are operated by a subsidiary of Geostar.
While we believe we have good beneficial title to our interest in EL 4416, the subsidiary of Geostar has not delivered to us a title assignment of our interest in a form to be recorded with Australian government officials. Various disputes have
arisen between us and Geostar regarding joint interest operations and billings, including the operations on EL 4416. We have sent a letter to Geostar demanding the arbitration of these issues. This proceeding is described in Footnote 16
Commitments and Contingencies - Litigation to our consolidated financial statements beginning on page F-1 of this report.

The
area on which EL 4416 is located is subject to native title claims. Three native title claims have been lodged over the area which includes EL 4416 in Victoria. The Gunai/Kurnai People claim is registered and two others, the Gunai/Kurnai/Boonerwring
claim and Kurnai People claim, are applications. The Kurnai People claim overlaps with the Gunai/Kurnai Peoples claim and have been in dispute for four to five years. The claims remain

in intra-indigenous mediation with the National Native Title Tribunal. The existence of these competing claims may prolong any mandatory negotiation process
undertaken in relation to this area.

Markets and Customers

The success of our operations is dependent upon prevailing prices for natural gas and
oil. The markets for natural gas and oil have historically been volatile and may continue to be volatile in the future. Natural gas and oil prices are beyond our control. However, rising demand for natural gas to fuel power generation and meet
increasing environmental requirements has led some industry observers to indicate that long-term demand for natural gas is increasing.

Our
current United States production has access to major intrastate and interstate pipeline systems. We contract to sell natural gas from our properties with spot market contracts that vary with market forces on a monthly basis. While overall natural
gas prices at major markets, such as Henry Hub in Louisiana, may have some impact on regional prices, the regional natural gas price at our production facilities may move somewhat independently of broad industry price trends. Because some of our
operations are located in specific regions, we are directly impacted by regional natural gas prices in those regions regardless of pricing at major market hubs. The East Texas Basin area has an extensive natural gas pipeline infrastructure in place.
Our deep Bossier production is transported to the Katy Hub in Katy, Texas, where numerous parties are available to purchase our natural gas production. Powder River Basin natural gas is sold under spot market contracts to major pipeline and natural
gas marketing companies. These companies purchase essentially all of our current production.

Australian natural gas markets and
infrastructure exist and are viable markets; however, they are not as developed as the markets and infrastructure in the United States. Specifically, the PEL 238 concession is currently not served by natural gas infrastructure. The initial gas
market for PEL 238 natural gas is anticipated to be an electricity generation facility owned and operated by our joint venture partner and located near the town of Narrabri, New South Wales, Australia. Although there currently is no pipeline from
the existing and planned CBM project areas, we and our joint venture partner are finalizing plans for a gathering system and pipeline to transport our CBM gas to the electricity generation facility.

The longer term market for PEL 238 natural gas is considered to be future gas-fired power generation facilities in New South Wales and the industrial and
residential markets in the Sydney-Newcastle-Wollongong areas of New South Wales. In March 2007, we announced that we had executed, along with our PEL 238 joint venture partner, a Memorandum of Understanding (MOU) with Macquarie
Generation, a government-owned electricity generator in the state of New South Wales, Australia. The MOU sets the framework for negotiation of a potential long-term agreement to supply natural gas for the expansion of Macquarie Generations
Bayswater power station.

The EL 4416 license in the Gippsland Basin of Victoria, the site of recent pilot CBM drilling and planned
production testing, is served by three existing natural gas transmission pipelines. The existing pipelines have capacity to transport natural gas from the EL 4416 license to markets in the area of Sydney, Melbourne and Tasmania. If our efforts
result in commercial CBM production from this license, minimal infrastructure expenditures would be necessary to connect to existing pipelines. Victoria has both a spot market for natural gas and a developed market for contract sales of natural gas.

Our very limited oil production in Texas and West Virginia is sold under spot sales transactions at market prices. The availability and
price responsiveness of the multiple oil purchasers provides for a highly competitive and liquid market for oil sales.

In February 2007,
we entered into a letter agreement with ETC Texas Pipeline, Ltd. that expands our existing transportation and treating agreement to meet the future gathering, treating and transportation of natural gas produced and owned or controlled by us in the
Hilltop area of East Texas. Under the letter agreement, ETC would construct a gathering system sufficient to gather and treat up to 150 MMcfd, and we would deliver to ETC a minimum of approximately 135 Bcf over a 10-year period. Minimum annual sales
over the 10-year period and fees for the gathering and treating of natural gas are currently being negotiated.

##### Table of Contents

##### Index to Financial Statements

During 2006, ETC Texas Pipeline Ltd. and Enserco Energy, Inc. accounted for 63% and 25% of our natural
gas and oil revenues, respectively. During 2005, ETC. and Enserco accounted for 65% and 26%, respectively, of our natural gas and oil revenues. During 2004, ETC and Western Gas Resources, Inc. accounted for 59% and 35%, respectively, of our natural
gas and oil revenues. Although ETC is the major natural gas purchaser and transporter in the area of our deep Bossier play and limited natural gas purchaser and transporter alternatives are currently available in this area, management believes that
other natural gas purchasers and transporters could ultimately be located thus minimizing a long-term material adverse impact on our financial condition or results of operations. Management believes that the loss of Enserco in the Powder River Basin
would not have a long-term material adverse impact on our financial position or results of operations, as there are numerous other purchasers operating in the Powder River Basin.

Competition

The natural gas and oil industry is intensely competitive and speculative in all of its phases. We
encounter competition from other natural gas and oil companies in all areas of our operations. In seeking suitable natural gas and oil properties for acquisition, we compete with other companies operating in our areas of interest, including large
natural gas and oil companies and other independent operators, which have greater financial resources and in many instances, have been engaged in the exploration and production business for a much longer time than we have. Many of our competitors
also have substantially larger operating staffs than we do. Many of these competitors not only explore for and produce natural gas and oil but also market natural gas and oil and other products on a regional, national or worldwide basis. These
competitors may be able to pay more for productive natural gas and oil properties and exploratory prospects and define, evaluate, bid for and purchase a greater number of properties and prospects than us. In addition, these competitors may have a
greater ability to continue exploration activities during periods of low market prices. Our ability to acquire additional properties and to discover reserves in the future will depend on our ability to evaluate and select suitable properties and to
consummate transactions in a highly competitive environment.

The prices of our natural gas and oil production are controlled by market
forces. However, competition in the natural gas and oil exploration industry also exists in the form of competition to acquire leases and obtain favorable transportation prices. We are relatively small and may have difficulty acquiring additional
acreage and/or projects and may have difficulty arranging for the transportation of our production. We also face competition in obtaining natural gas and oil drilling rigs and in sourcing the manpower to run them and provide related services.

Governmental Regulation

In addition to the environmental regulations discussed below under the heading
Environmental Regulation, our natural gas and oil exploration, production and related operations are subject to extensive rules and regulations promulgated in the United States and Australia. These laws and regulations, all of which are
subject to change from time to time, include matters relating to land tenure; drilling and production practices such as discharge permits and the spacing of wells; the disposal of water resulting from operations and the processing, handling and
disposal of hazardous materials such as hydrocarbons and naturally occurring radioactive materials; bonding requirements; ongoing obligations for licensing; reporting requirements; marketing and pricing policies; royalties; taxation; and foreign
trade and investment.

Failure to comply with these rules and regulations can result in substantial penalties. Furthermore, we could be
liable for personal injuries, property damage, spills, discharge of hazardous materials, reclamation costs, remediation, clean-up costs and other environmental damages as a consequence of acquiring a natural gas or oil opportunity.

The regulatory burden on the natural gas and oil industry increases our cost of doing business and affects our financial condition. Although we believe
we are in substantial compliance with all applicable laws and regulations, we are unable to predict the future cost or impact of complying with such laws because those laws



5



---

##### Table of Contents

##### Index to Financial Statements

and regulations are frequently amended or reinterpreted. We are unable to predict what additional legislation or amendments may be proposed that will affect
our operations or when any such proposals, if enacted, might become effective.

U.S. Governmental Regulation

Transportation and Sale of Natural Gas.    Historically, the transportation and sale for resale of natural gas in interstate
commerce have been regulated pursuant to the Natural Gas Act of 1938, the Natural Gas Policy Act of 1978 and the regulations promulgated thereunder by the Federal Energy Regulatory Commission (FERC). In the past, the federal government has regulated
the prices at which natural gas could be sold. Deregulation of natural gas sales by producers began with the enactment of the Natural Gas Policy Act of 1978. In 1989, Congress enacted the Natural Gas Wellhead Decontrol Act, which removed all
remaining Natural Gas Act of 1938 and Natural Gas Policy Act of 1978 price and non-price controls affecting producer sales of natural gas effective January 1, 1993. Congress could, however, re-enact price controls in the future.

FERC regulates interstate natural gas pipeline transportation rates and service conditions, which affect the marketing of natural gas produced by us and
the revenues received by us for sales of such natural gas. FERC requires interstate pipelines to provide open-access transportation on a non-discriminatory basis for all natural gas shippers. FERC frequently reviews and modifies its regulations
regarding the transportation of natural gas with the stated goal of fostering competition within all phases of the natural gas industry. In addition, with respect to production onshore or in state waters, the intra-state transportation of natural
gas would be subject to state regulatory jurisdiction as well.

Additional proposals and proceedings that might affect the natural gas
industry are considered from time to time by Congress, FERC, state regulatory bodies and the courts. We cannot predict when or if any such proposals might become effective or their effect, if any, on our operations. The natural gas industry
historically has been closely regulated; thus, there is no assurance that the less stringent regulatory approach recently pursued by FERC and Congress will continue indefinitely into the future. We do not believe that we will be affected by any
action taken in a materially different way than other natural gas producers, gatherers and marketers with which we compete.

Federal
Regulation of Sales and Transportation of Crude Oil.    Our sales of crude oil and condensate are not currently regulated and are made at market prices. In a number of instances, however, the ability to transport and sell
such products is dependent on pipelines whose rates, terms and conditions of service are subject to FERC jurisdiction under the Interstate Commerce Act. Certain regulations implemented by FERC in recent years could result in an increase in the cost
of pipeline transportation service. We do not believe, however, that these regulations affect us any differently than other producers.

Our
operations are subject to extensive and continually changing regulation affecting the natural gas and oil industry. Many departments and agencies, both federal and state are authorized by statute to issue, and have issued, rules and regulations
binding on the natural gas and oil industry and its individual participants. The failure to comply with such rules and regulations can result in substantial penalties. The regulatory burden on the natural gas and oil industry increases our cost of
doing business and, consequently, affects our profitability. We do not believe that we are affected in a significantly different manner by these regulations than are our competitors.

Regulation of Production.    The production of natural gas and oil is subject to regulation under a wide range of state and
federal statutes, rules, orders and regulations. State and federal statutes and regulations require permits for drilling operations, drilling bonds, and reports concerning operations. Most states in which we own and operate properties, have
regulations governing conservation matters, including provisions for the unitization or pooling of the natural gas and oil properties, the establishment of maximum rates of production from oil and natural gas wells, the spacing of wells, and the
plugging and abandonment of wells and removal of related production equipment. Many states also restrict production to the market demand for the natural gas and oil and several states have indicated interests in revising applicable regulations.
These regulations can limit the amount



6

##### Table of Contents

##### Index to Financial Statements

of the natural gas and oil we can produce from our wells, limit the number of wells, or limit the locations at which we can conduct drilling operations.
Moreover, each state generally imposes a production or severance tax with respect to production and sale of natural gas, natural gas liquids and crude oil within its jurisdiction.

Australian Governmental Regulation

Commonwealth and State Laws and
Regulations.    The regulation of the activities of participants in the natural gas and oil industry in Australia is similar to that of the United States, in that regulatory controls are imposed at both the state and
commonwealth (federal) levels. Specific commonwealth regulations impose environmental, petroleum industry licensing, foreign investment, cultural heritage and native title restrictions on accessing resources in Australia. These regulations are in
addition to any state level regulations.

Foreign Investment Regulation.Foreign investment in Australia is
regulated by the commonwealth through its foreign investment legislation and policy. In some circumstances, Australian foreign investment regulation and policy requires foreign interests to obtain prior approval from the Treasurer before investing
in specific industry sectors. The Foreign Investment Review Board administers the regulation of foreign investment on behalf of the commonwealth. Its functions include analyzing proposals by foreign interests for investment in Australia and making
recommendations to the Government on the compatibility of those proposals with Government policy and the relevant legislation. In some circumstances the acquisition of, investment in or formation of a new business will require review and approval
under the commonwealth foreign investment policy and regulations.

Native title.Australian law recognizes
that in some instances native title, that is the laws and customs of the Aboriginal inhabitants, has survived European settlement. Native title will only survive if it has not been extinguished. Native title may be extinguished by an Act of
Government, such as the creation of a title that is inconsistent with native title. This may include a grant of the right to exclusive possession through freehold title or lease. Native title may also be extinguished if the connection between the
land and the group of Aboriginal people claiming native title has been lost. Native title legislation was enacted in 1993 in order to provide a statutory framework for deciding questions such as where native title exists, who holds native title and
the nature of native title which were left unanswered by a landmark 1992 Australian High Court decision. Native title claims by Aboriginal groups can include claims over existing and potential natural gas and oil exploration and development areas.
If we apply to the relevant State or Territory for an onshore exploration permit or production license over Crown land or Aboriginal land which has a registered native title claimant or a registered native title holder, we will have to
go through a mandatory negotiation process, followed by an arbitration conducted by the National Native Title Tribunal if no agreement can be reached through negotiation. The results of the negotiation may impose significant financial obligations on
us. Each application for an exploration permit, production license or a pipeline license must be examined individually in order to determine the existence of native title claims. Native title claims can impact the validity of any rights granted to
us if they affect native title and have been granted other than in compliance with the Native Title Act 1993 (Cth) after 1993. Depending on the locality of a project other access rights form private or Crown land holders may also need to be
obtained.

Australian Petroleum Regulation and Gas Markets.    All petroleum tenements in which we hold an
interest are subject to specific licensing regulation in the relevant States. Each exploration permit or production license will (depending on the nature of the license and the State in which the project is located) be issued subject to various
obligations. These may include obligations as to expenditure, payment of rent, consultation with occupiers and rehabilitation. These obligations must be met to maintain the good standing of the tenement Licenses may be cancelled or revoked for non
compliance. In Australia the ownership of minerals (including petroleum) is vested in the Government (the Crown) and ownership only passes to the license holder once the relevant mineral is extracted. We are required to pay Government royalties of
10% of the wellhead value of petroleum extracted. Several statutory mechanisms regulate access rights to a range of infrastructure in Australia including gas transmission pipelines. These involve generic access regulations contained in the Trade
Practices Act 1974 Cth.and industry specific schemes contained in specific legislative instruments, industry codes and schemes. Objectives of this regulatory regime include providing a process for establishing third party access to



7

##### Index to Financial Statements

natural gas pipelines, facilitating the development and operation of a national natural gas market, promoting a competitive market for natural gas in which
customers are able to choose their supplier, and providing a right of access to transmission and distribution networks on fair and reasonable terms and conditions. We cannot currently ascertain the impact of the regime objectives on our operations
but believe it could benefit us.

Environmental Regulation

Our natural gas and oil exploration and production operations and similar operations
that we do not operate but in which we own a working interest in the United States are subject to significant federal, state and local environmental laws and regulations governing environmental protection as well as the discharge of substances into
the environment. These laws and regulations may restrict the types, quantities and concentrations of various substances that can be released into the environment as a result of natural gas and oil drilling, production and processing activities;
suspend, limit or prohibit construction, drilling and other activities in certain lands lying within wilderness, wetlands and other protected areas; require remedial measures to mitigate pollution from historical and on-going operations such as the
use of pits and plugging of abandoned wells; and restrict injection of liquids into subsurface strata that may contaminate groundwater. Governmental authorities have the power to enforce compliance with their laws, regulations and permits, and
violations may result in the issuance of injunctions limiting or prohibiting operations, as well as administrative, civil and even criminal penalties. The effects of these laws and regulations, as well as the assessment of other laws or regulations
that are adopted in the future, could have a material adverse impact on our operations and other operations in which we own an interest. As discussed below, our Australian operations are similarly subject to regulation by Australian authorities.

We believe that we are in substantial compliance with existing applicable environmental laws and regulations. However, it is possible that
new environmental laws and regulations or the modification or more stringent enforcement of existing laws and regulations could have a material adverse effect on our operations and other operations in which we own an interest. As a general matter,
the recent trend in environmental legislation and regulation is toward stricter standards, and this trend will likely continue. To date, we have not been required to expend significant resources in order to satisfy existing applicable environmental
laws and regulations. However, there is no assurance that costs to comply with existing and any new environmental laws and regulations in the future will not be material. In addition, if substantial liabilities to third parties or governmental
entities are incurred, the payment of such claims may reduce or eliminate the funds available for project investment or result in loss of our properties. Moreover, a serious incident of pollution may result in the suspension or cessation of
operations in the affected area. Although we maintain insurance coverage against costs of clean-up operations, no assurance can be given that we are fully insured against all such potential risks. The imposition of any of these liabilities or
compliance obligations on us may have a material adverse effect on our financial condition and results of operations.

The following is a
summary of some of the existing environmental laws, rules and regulations to which our business operations are subject.

U.S. Environmental
Regulations

In the United States, environmental laws are implemented principally by the United States Environmental Protection
Agency, or EPA, the Department of Transportation and the Department of the Interior, as well as other comparable state agencies.

Comprehensive Environmental Response, Compensation and Liability Act.    The Comprehensive Environmental Response, Compensation and Liability Act, or CERCLA, also known as the Superfund law, imposes strict, joint
and several liability without regard to fault or legality of conduct, on persons who are considered to have contributed to the release of a hazardous substance into the environment. These persons include the owner or operator of the site
where the release occurred and companies that disposed or arranged for the disposal of the hazardous substance released at the site. Under CERCLA, such persons may be liable for the costs of cleaning up the hazardous substances that have been
released into the environment, for damages to natural resources and for the costs of certain health studies. In addition, it is not uncommon for neighboring land

owners and other third parties to file claims for personal injury and property damage allegedly caused by the hazardous substances released into the
environment. Although CERCLA currently excludes petroleum and natural gas, natural gas liquids, liquefied natural gas or synthetic gas useable for fuel, from the definition of hazardous substance, our operations
as well as other operations in which we own an interest may generate materials that are subject to regulation as hazardous substances under CERCLA.

CERCLA may require payment for cleanup of certain abandoned waste disposal sites, even if such waste disposal activities were undertaken in compliance with regulations applicable at the time of disposal. Under CERCLA, one party may, under
certain circumstances, be required to bear more than its proportional share of cleanup costs if payment cannot be obtained from other responsible parties. CERCLA authorizes the EPA and, in some cases, third parties to take actions in response to
threats to the public health or the environment and to seek to recover from the responsible classes of persons the costs they incur. The scope of financial liability under these laws involves inherent uncertainties.

Resource Conservation and Recovery Act.    The Resource Conservation and Recovery Act, or RCRA, and comparable state programs
regulate the management, treatment, storage and disposal of hazardous and non-hazardous solid wastes. Our operations and other operations in which we own an interest generate wastes, including hazardous wastes that are subject to RCRA and comparable
state laws. We believe that these operations are currently complying in all material respects with applicable RCRA requirements. Although RCRA currently exempts certain natural gas and oil exploration and production wastes from the definition of
hazardous waste, we cannot assure you that this exemption will be preserved in the future, which could have a significant impact on us as well as of the natural gas and oil industry in general.

We currently own, lease, own a working interest in, or operate numerous properties that for many years have been used by third parties for the
exploration and production of natural gas and oil. Although we abide by standard industry operating and disposal practices, hazardous substances, wastes, or hydrocarbons may have been released on or under the properties owned or leased by us or in
which we own an interest, or on or under other locations, including off-site locations, where such substances have been taken for disposal or recycling. In addition, many of these properties have been operated by third parties or by previous owners
or operators whose treatment and disposal of hazardous substances, wastes, or hydrocarbons was not under our control. These properties and the substances disposed or released on them may be subject to CERCLA, RCRA and analogous state laws. Under
such laws, we could be required to remove previously disposed substances and wastes (including substances disposed of or released by prior owners or operators), remediate contaminated property, or perform remedial plugging or pit closure operations
to prevent future contamination.

Water Discharges.Our operations and other operations in which we own a
working interest are subject to the Clean Water Act, or CWA, as well as the Oil Pollution Act, or OPA, and analogous state laws and regulations. These laws and regulations impose detailed requirements and strict controls regarding the discharge of
pollutants, including spills and leaks of oil and other substances, into waters of the United States, including wetlands. Under the CWA and OPA, any unpermitted release of pollutants from operations could cause us to become subject to the costs of
remediating a release; administrative, civil or criminal fines or penalties; or OPA specified damages, such as damages for loss of use and natural resource damages. In addition, in the event that spills or releases of produced water from natural gas
and oil production operations were to occur, we would be subject to spill notification and response requirements under the CWA or the equivalent state regulatory program. Depending on the nature and location of these operations, spill response plans
may also have to be prepared.

Our natural gas and oil exploration and production operations and other operations in which we own an
interest generate produced water as a waste material, which is subject to the disposal requirements of the CWA, Safe Drinking Water Act, or SDWA, or an equivalent state regulatory program. Naturally occurring groundwater is also typically produced
by CBM production in our operations or in other operations in which we own an interest. This produced water is disposed of by re-injection into the subsurface through disposal wells, discharge to the surface, or in evaporation ponds. Whichever
disposal method is used, produced water must be disposed of in compliance with permits issued by regulatory agencies, and in compliance with applicable environmental



9

##### Index to Financial Statements

regulations. This water can sometimes be disposed of by discharging it under discharge permits issued pursuant to the CWA or an equivalent state program.
Another common method of produced water disposal is subsurface injection in disposal wells. Such disposal wells are permitted under the SDWA, or an equivalent state regulatory program. To date, we believe that all necessary surface discharge or
disposal well permits have been obtained and that the produced water has been discharged into the produced water disposal wells in substantial compliance with such obtained permits and applicable laws. Nonetheless, in connection with CBM production
in the Powder River Basin, a concern common to many operators in the basin is the potential for opposition by individuals or groups to the issuance of a permit for the discharge or disposal of water generated by production activities. Such
opposition could result in delays, limitations, or denials with respect to environmental or other approvals necessary to develop our acreage in the Powder River Basin, which could adversely affect our financial condition or results of operations.

Air Emissions.    The Clean Air Act, or CAA, and comparable state laws and regulations govern emissions of
various air pollutants through the issuance of permits and the imposition of other requirements. Air emissions from some equipment found at our operations or other operations in which we own an interest, such as gas compressors, are potentially
subject to regulations under the Clean Air Act or equivalent state and local regulatory programs, although many small air emission sources are expressly exempt from such regulations. To the extent that these air emissions are regulated, they are
generally regulated by permits issued by state regulatory agencies. To date, we believe that no unusual difficulties have been encountered in obtaining air permits. However, there is no assurance in the future, we will not be required to incur
capital expenditures in connection with maintaining or obtaining operating permits and approvals addressing air emission-related issues.

CBM production operations involve the use of gas-fired compressors to transport gas that is produced. Emissions of combustible by-products from compressors at one location may be large enough to subject the compressors to CAA and comparable
state air quality regulation requirements for pre-construction and operating permits. To date, we believe that such gas-fired compressors operated by us or at other operations in which we own a working interest have been operated in substantial
compliance with obtained permits and the applicable federal, state and local laws and regulations without undue cost to or burden on our business activities. Another air emission associated with these CBM operations that may be subject to regulation
and permitting requirements is particulate matter resulting from construction activities and vehicle traffic. To date, we do not believe there has been any unusual difficulty in complying with requirements related to particulate matter.

Other Laws and Regulations.Our operations and other operations in which we own a working interest are also impacted by
regulations governing the handling, transportation, storage and disposal of naturally occurring radioactive materials. Furthermore, owners, lessees and operators of natural gas and oil properties are also subject to increasing civil liability
brought by surface owners and adjoining property owners. Such claims are predicated on the damage to or contamination of land resources occasioned by drilling and production operations and the products derived therefrom, and are often based on
negligence, trespass, nuisance, strict liability or fraud.

In response to recent studies suggesting that emissions of certain gases
including carbon dioxide, may be contributing to warming of the Earths atmosphere, many foreign nations have agreed to limit emissions of these gases, generally referred to as greenhouse gases, pursuant to the United Nations
Framework Convention on Climate Change, also known as the Kyoto Protocol. Although the United States is not participating in the Kyoto Protocol, the current session of Congress is considering climate change legislation, with multiple
bills having already been introduced in the Senate that propose to restrict greenhouse gas emissions. By comparison, several states have already adopted legislation, regulations and/or regulatory initiatives to reduce emissions of greenhouse gases.
Also, on November 29, 2006, the U.S. Supreme Court heard arguments on a case appealed from the U.S. Circuit Court of Appeals for the District Columbia, Massachusetts, et al. v. EPA, in which the appellate court held that the U.S.
Environmental Protection Agency had discretion under the federal Clean Air Act to refuse to regulate carbon dioxide emissions from mobile sources. Passage of climate change legislation by Congress or a Supreme Court reversal of the appellate
decision could result in federal regulation of carbon dioxide emissions and other greenhouse gases. In particular, the natural gas and oil exploration and production industry is a direct source of certain greenhouse gas emissions, namely carbon
dioxide and methane, and future restrictions on such emissions could impact our future operations. Our operations and other operations in which

we own an interest currently are not adversely impacted by current federal, state and local climate change initiatives; however, it is not possible to
accurately estimate how potential future laws and regulations restricting emissions of greenhouse gases in areas of the United States in which we conduct business would adversely affect our operations and other operations in which we own an
interest.

Finally, legislation continues to be introduced in Congress and development of regulations continues in the Department of
Homeland Security and other agencies concerning the security of industrial facilities, including natural gas and oil facilities. Our operations and the operations of the natural gas and oil industry in general may be subject to such laws and
regulations. Presently, it is not possible to accurately estimate the costs we could incur to comply with any such facility security laws or regulations, but such expenditures could be substantial.

Australian Environmental Regulations

Australia has environmental laws and regulations that are similar in scope and impact to United States environmental laws and regulations. Similar approval, licensing and operational impacts apply at a commonwealth, state and local
government level. As a result, environmental laws and regulations can result in similar licensing and operational impacts in Australia that are similar to those discussed above with respect to the United States.

The legislation regulating environmental assessment at a commonwealth level is the Environmental Protection and Biodiversity Conservation Act 1999
(Cth.). This Commonwealth Act establishes a regime for protecting the environment, flora and fauna biodiversity and Australian national heritage. It requires any person taking an action which could have a significant impact on one of these
values to refer it to the commonwealth Minister for the Environment for consideration and potential assessment. The Act only applies to matters of national environmental or heritage significance. These are matters which impact on a world heritage
site, Ramsar wetlands, species which are listed as threatened under the Act, migratory species, nuclear actions and commonwealth marine areas or places listed on the commonwealth heritage list. Operators are required to assess their projects to
determine whether an action is likely to have a significant impact on matters of national environmental significance, and make a decision respecting submission of that assessment to a public referral process. The referral is expected to add time to
the existing approval process but its effect on a project will depend on the significance of the impact identified. In addition, see the discussion in BusinessGunnedah Basin, New South Wales, Australia for a discussion of the New
South Wales governments bioregion study involving PEL 238.

Environmental protection and planning issues are also regulated in each
State and Territory by specific legislation enacted by each State or Territory. The governments of New South Wales and Victoria both have a suite of legislation regulating environmental matters in their States. Generally speaking, onshore natural
gas and oil projects in New South Wales and Victoria require an environmental approval from the State (and sometimes Commonwealth) Government, land use planning approval from local government and an approval under the relevant petroleum regime (as
referred to above. Legislation provides for the integrated assessment of these issues. The environmental regulators in both New South Wales and Victoria have the ability to require a project operator to prepare and implement a plan to improve the
environmental performance of a project, and may also amend the conditions on an existing environmental approval. As such, the environmental regulation of a project may not be assumed to remain static following approval, and may become more onerous
over time. The legislation imposes a licensing approval and contamination management scheme which may impact on our operations and impose a liability which may extend beyond the time period during which properties are operated, occupied or owned.
The laws and regulations also restrict emissions to air, land and water and may control or regulate substances which can be released into the environment and the manner in which they are transported and disposed of. Approvals will usually include
terms which require remediation and reinstatement obligations for the site during the course of operations and following closure of the project.

Australian laws and regulations protecting archeological relics, cultural, natural and built heritage as well as native flora and fauna can also impact on our operations and impose obligations in respect of restitution or

replacement, as well as liability in respect of damage. In particular, indigenous cultural heritage protection laws are becoming increasingly stringent and
in many States and the Northern Territory the specialist indigenous heritage protection laws require a proponent to negotiate directly with indigenous groups with respect to a major project.

Employees

As of March 20, 2007, we had 19 employees, all of whom are full time. We use the services of
independent consultants and contractors to perform various professional services, including reservoir engineering, land, legal, regulatory reporting, environmental and tax services. On those properties where we are not the operator, we rely on
outside operators to drill, produce and market our natural gas and oil. Our employees do not belong to a union or have a collective bargaining organization. Management considers its relationship with employees to be good.

Corporate Offices

We lease our corporate offices at 1331 Lamar Street, Suite 1080, Houston, Texas 77010. Our
office space covers 9,332 square feet at a monthly rental of $17,100 through October 2010. During 2006, we maintained an office in Miami, Florida (our Chief Executive Officers city of residence) at a monthly rental of $2,700 per month.

Natural gas and oil prices are volatile and a decline in natural gas and oil prices can significantly affect our
financial condition and results of operations.

The success of our business greatly depends on market prices of natural gas and oil.
The higher market prices are, the more likely it is that we will be financially successful. On the other hand, declines in natural gas or oil prices may have a material adverse affect our financial condition, profitability and liquidity. Lower
prices also may reduce the amount of natural gas or oil that we can produce economically. Natural gas and oil are commodities whose prices are set by broad market forces. Historically, the natural gas and oil markets have been volatile. Natural gas
and oil prices will likely continue to be volatile in the future. Prices for natural gas and oil are subject to wide fluctuations in response to relatively minor changes in the supply of and demand for natural gas or oil, market uncertainty and a
variety of additional factors that are beyond our control. These factors include:



| |  |  | The domestic and foreign supply of natural gas and oil;
| | - |  | -------------------------------------------------------



| |  |  | Overall economic conditions;
| | - |  | ----------------------------



| |  |  | Weather conditions;
| | - |  | -------------------



| |  |  | Political conditions in the Middle East and other oil producing regions;
| | - |  | ------------------------------------------------------------------------



| |  |  | Domestic and foreign governmental regulations;
| | - |  | ----------------------------------------------



| |  |  | The level of consumer product demand; and
| | - |  | -----------------------------------------



| |  |  | The price and availability of alternative fuels.
| | - |  | ------------------------------------------------

Our success is influenced by natural gas prices in the specific areas where we operate, and these prices may be lower than prices at major markets.

Even though overall natural gas prices at major markets, such as Henry Hub in Louisiana, may be high, regional natural gas prices may move somewhat independent of broad industry price trends. Because some of our
operations are located outside major markets, we are directly impacted by regional natural gas prices regardless of Henry Hub or other major market pricing. For example, surplus natural gas supplies relative to available transportation in the Powder
River Basin in 2002 caused local natural gas prices to be much less than national natural gas prices, and we, therefore, were unable to take advantage of those higher national natural gas prices. Low natural gas prices in any or all of the areas
where we operate would negatively impact our financial condition and results of operations.

Natural gas and oil reserves are depleting assets, and
the failure to replace our reserves would adversely affect our production and cash flows.

Our future natural gas and oil production
depends on our success in finding or acquiring new reserves. If we fail to replace reserves, our level of production and cash flows would be adversely impacted. Production from natural gas and oil properties decline as reserves are depleted, with
the rate of decline depending on reservoir characteristics. Our total proved reserves will decline as reserves are produced unless we conduct other successful exploration and development activities or acquire properties containing proved reserves,
or both. Our ability to make the necessary capital investment to maintain or expand our asset base of natural gas and oil reserves would be impaired to the extent cash flow from operations is reduced and external sources of capital become limited or
unavailable. We may not be successful in exploring for, developing or acquiring additional reserves. If we are not successful, our future production and revenues will be materially adversely affected.

Exploration is a high risk activity, and our participation in drilling activities may not be successful.

Our future success will largely depend on the success of our exploration drilling program. Participation in exploration drilling activities involves
numerous risks, including the risk that no commercially productive natural



13

gas or oil reservoirs will be discovered. The cost of drilling, completing and operating wells is often uncertain, and drilling operations may be curtailed,
delayed or canceled as a result of a variety of factors, including:



| |  |  | Unexpected drilling conditions;
| | - |  | -------------------------------



| |  |  | Blowouts, fires or explosions with resultant injury, death or environmental damage;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | Pressure or irregularities in formations;
| | - |  | -----------------------------------------



| |  |  | Equipment failures or accidents;
| | - |  | --------------------------------



| |  |  | Adverse weather conditions;
| | - |  | ---------------------------



| |  |  | Compliance with governmental requirements and laws, present and future; and
| | - |  | ---------------------------------------------------------------------------



| |  |  | Shortages or delays in the availability of drilling rigs and the delivery of equipment.
| | - |  | ---------------------------------------------------------------------------------------

We use available seismic data to assist in the location of potential drilling sites. Even when properly used and interpreted, 2-D and 3-D seismic data
and other visualization techniques are only tools used to assist geoscientists in identifying subsurface structures and hydrocarbon indicators. They do not allow the interpreter to know conclusively if hydrocarbons are present or economically
producible. Poor results from our drilling activities would have a material adverse affect our financial condition, future cash flows and results of operations. In addition, using seismic data and other advanced technologies involves substantial
upfront costs and is more expensive than traditional drilling strategies, and we could incur losses as a result of these expenditures.

We have
incurred significant net losses since our inception and may incur additional significant net losses in the future.

We have not been
profitable since we started our business. We incurred net losses of $84.8 million and $25.7 million for the years ended December 31, 2006 and 2005, respectively. Our capital has been employed in an increasingly expanding natural gas and oil
exploration and development program with the focus on finding significant natural gas and oil reserves and producing from them over the long-term rather than focusing on achieving immediate net income. The uncertainties described in this section may
impede our ability to ultimately find, develop and exploit natural gas and oil reserves. As a result, we may not be able to achieve or sustain profitability or positive cash flows from operating activities in the future.

Our level of indebtedness reduces our financial and operational flexibility, and our level of indebtedness may increase.

As of December 31, 2006, the principal amount of our long-term debt was $106.3 million. Our level of indebtedness affects our operations in several
ways, including the following:



| |  |  | A significant portion of our cash flow must be used to service our indebtedness;
| | - |  | --------------------------------------------------------------------------------



| |  |  | A high level of debt increases our vulnerability to general adverse economic and industry conditions;
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | The covenants contained in the agreements governing our outstanding indebtedness limit our ability to borrow additional funds, dispose of assets, pay dividends,
sell common shares below certain prices and make certain investments;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Although we have the ability, subject to the limitations specified in the agreement, to borrow an additional $10.0 million of senior secured notes through June
2007, the terms of our senior secured notes prohibit us from borrowing funds senior or pari passu to the senior secured notes and may limit our ability to borrow subordinated funds;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our debt covenants may also affect our flexibility in planning for, and reacting to, changes in the economy or in our industry;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------

| |  |  | A high level of debt may impair our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions or general
corporate purposes; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | A default under our senior secured note covenants could result in required principal payments that we may not be able to meet, resulting in higher penalty interest
rates and/or debt maturity acceleration.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We may incur additional debt, including significant additional secured
indebtedness, in order to develop our properties in accordance with our business plan for the next twelve months. A higher level of indebtedness increases the risk that we may default on our debt obligations. Our ability to meet our debt obligations
and to reduce our level of indebtedness depends on our future performance. General economic conditions, natural gas and oil prices and financial, business and other factors affect our operations and our future performance. Many of these factors are
beyond our control. We may not be able to generate sufficient cash flow to pay the interest on our debt and future working capital, borrowings or equity financing may not be available to pay or refinance such debt. Factors that will affect our
ability to raise cash through an offering of our capital stock or a refinancing of our debt include financial market conditions, the value of our assets and our performance at the time we need capital.

Disputes have arisen between the Company and Geostar in connection with the POA and general operating and administrative activity,

Over the past six years, we have entered into various transactions or agreements with Geostar, a related party. In 2001, the Company entered into a
Participation and Operating Agreement (the POA) with Geostar that governed the joint Geostar and Company United States and Australian property acquisition and exploration and development activities. We have also requested that
Geostars Australian subsidiary provide a record title assignment of our beneficial interests in EL 4416, the exploration license in the Gippsland Basin property in Victoria, Australia. Various disputes have arisen, primarily over the past
year, in connection with the POA and general operating and administrative activity between Geostar and us, including claims by Geostar that we owe Geostar approximately $3.0 million of additional charges for operating and administrative costs not
previously billed and approximately $11.0 million in demands for finder fees for funds previously provided by Geostar on our behalf. Although we strongly contend that these additional Geostar charges are without merit and that Geostar owes us
approximately $3.8 million at December 31, 2006, we may not prevail. Payment to Geostar of the amounts asserted would have a material adverse effect on our financial position.

Deficiencies of title to our leased interests could significantly affect our financial condition.

Our practice in acquiring exploration leases or undivided interests in natural gas and oil leases is not to incur the expense of retaining lawyers to examine the title to the mineral interest prior to executing the lease. Instead, we rely
upon the judgment of lease brokers and others to perform the field work in examining records in the appropriate governmental or county clerks office before leasing a specific mineral interest. This practice is widely followed in the industry.
Prior to the drilling of an exploration well, the operator of the well will typically obtain a preliminary title review of the drillsite lease and/or spacing unit within which the proposed well is to be drilled to identify any obvious deficiencies
in title to the well and, if there are deficiencies, to identify measures necessary to cure those defects to the extent reasonably possible. However, such deficiencies may have been cured by the operator of any such wells. It does happen, from time
to time, that the examination made by the title lawyers reveals that the lease or leases are invalid, having been purchased in error from a person who is not the rightful owner of the mineral interest desired. In these circumstances, we may not be
able to proceed with our exploration and development of the lease site or may incur costs to remedy a defect, which could affect our financial condition and results of operations. Information about our legal proceedings is set forth in Footnote 16
Commitments and ContingenciesLitigation to our consolidated financial statements, which begins on page F-1.

Reserve estimates
depend on many assumptions that may turn out to be inaccurate. Any material inaccuracies in these reserve estimates or underlying assumptions could materially affect the quantities and present values of our reserves.

The process of estimating natural gas and oil reserves is complex. It requires interpretations of available technical data and various assumptions,
including assumptions relating to economic factors. Any significant



15

##### Table of Contents

##### Index to Financial Statements

inaccuracies in these interpretations or assumptions could materially affect the estimated quantities and present value of reserves.

There are many uncertainties inherent in estimating natural gas and oil reserves and their values, many of which are beyond our control. Reservoir
engineering is a subjective process of estimating underground accumulations of natural gas or oil that cannot be measured in an exact manner. Estimates of economically recoverable natural gas or oil reserves and of future net cash flows necessarily
depend on many variables and assumptions, such as:



| |  |  | Historical natural gas or oil production from that area, compared with production from other producing areas;
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | The assumed effects of regulations by governmental agencies;
| | - |  | ------------------------------------------------------------



| |  |  | Assumptions concerning future prices;
| | - |  | -------------------------------------



| |  |  | Assumptions concerning future operating costs;
| | - |  | ----------------------------------------------



| |  |  | Assumptions concerning severance and excise taxes; and
| | - |  | ------------------------------------------------------



| |  |  | Assumptions concerning development costs and workover and remedial costs.
| | - |  | -------------------------------------------------------------------------

Any of these assumptions could vary considerably from actual results. For these reasons, estimates of the economically recoverable quantities of natural
gas or oil attributable to any particular group of properties, classifications of those reserves based on risk recovery and estimates of the future net cash flows expected from them prepared by different engineers, or by the same engineer at
different times, may vary substantially. Because of this, our reserve estimates may materially change at any time.

You should not consider
the present values of estimated future net cash flows referred to in this Form 10-K to be the current market value of the estimated reserves attributable to our properties. The estimated discounted future net cash flows from proved reserves are
generally based on prices and costs in effect when the estimate is made. However, actual future prices and costs may be materially higher or lower. Actual future net cash flows also will be affected by factors such as:



| |  |  | The amount and timing of actual production, supply and demand for natural gas or oil;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | Curtailments or increases in consumption of natural gas or oil;
| | - |  | ---------------------------------------------------------------



| |  |  | Changes in governmental regulations or taxation; and
| | - |  | ----------------------------------------------------



| |  |  | The timing of both production and expenses in connection with the development and production of natural gas or oil properties.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------

In this Form 10-K, the net present value of future net revenues is calculated using a 10% discount rate. This rate is not necessarily the most
appropriate discount factor based on interest rates in effect from time to time and risks associated with our reserves or the natural gas and oil industry in general.

The imprecise nature of estimating proved natural gas and oil reserves, future downward revisions of proved reserves and increased drilling expenditures without current additions to proved reserves may lead to
write downs in the carrying value of our natural gas and oil properties.

Due to the imprecise nature of estimating natural gas and
oil reserves as well as the potential volatility in natural gas and oil prices and their effect on the carrying value of our natural gas and oil properties, write downs in the future may be required as a result of factors that may negatively affect
the present value of proved natural gas and oil reserves. These factors can include volatile natural gas and oil prices, downward revisions in estimated proved natural gas and oil reserve quantities, limited classification of proved reserves
associated with successful wells and unsuccessful drilling activities.

A majority of our proved reserves are classified as proved developed non-producing and proved undeveloped and may
ultimately prove to be less than estimated.

At December 31, 2006, approximately 63.5% of our total proved reserves were
classified as proved developed non-producing and proved undeveloped. It will take substantial capital to recomplete or drill our non-producing and undeveloped locations. Our estimate of proved reserves at December 31, 2006 assumes that we will
spend significant development capital expenditures to develop these reserves, including an estimated $30.9 million in 2007. Further, our drilling efforts may be delayed or unsuccessful, and actual reserves may prove to be less than current reserve
estimates, which could have a material adverse effect on our financial condition and results of operations.

We may experience shortages of equipment
and personnel, which could significantly disrupt or delay our operations.

From time to time, there has been a general shortage of
drilling rigs, equipment, supplies and oilfield services in North America and Australia, which could intensify with increased industry activity. In addition, the costs and delivery times of rigs, equipment and supplies have risen. Shortages of
drilling rigs, equipment, supplies or trained personnel could delay and adversely affect our operations and drilling plans, which could have an adverse effect on our results of operations. While we intend to enter into contracts for the services of
drilling rigs in North America and Australia, we may not be successful in doing so. The demand for, and wage rates of, qualified rig crews have begun to rise in the drilling industry due to the increasing number of active rigs in service. Personnel
shortages have occurred in the past during times of increasing demand for drilling services. If the number of active drilling rigs increases, we may experience shortages of qualified personnel to operate our drilling rigs, which could delay our
drilling operations and adversely affect our business.

We are subject to complex laws and regulations, including environmental laws and regulations
that can adversely affect the cost, manner or feasibility of conducting our business.

Our exploration and production interests and
operations are subject to stringent and complex federal, state and local laws and regulations governing the operation and maintenance of our facilities and the handling and discharge of substances into the environment. These existing laws and
regulations impose numerous obligations that are applicable to our interests and operations including:



| |  |  | Air and water discharge permits for drilling and production operations;
| | - |  | -----------------------------------------------------------------------



| |  |  | Drilling and abandonment bonds or other financial responsibility assurances;
| | - |  | ----------------------------------------------------------------------------



| |  |  | Reports concerning operations;
| | - |  | ------------------------------



| |  |  | Spacing of wells;
| | - |  | -----------------



| |  |  | Access to properties, particularly in the Powder River Basin;
| | - |  | -------------------------------------------------------------



| |  |  | Taxation; and
| | - |  | -------------



| |  |  | Other regulatory controls on operating activities.
| | - |  | --------------------------------------------------

In addition, regulatory agencies have from time to time imposed price controls and limitations on production by restricting the flow rate of wells below actual production capacity in order to conserve supplies of
natural gas and oil.

Failure to comply with environmental and other laws and regulations applicable to our interests and operations could
result in the assessment of administrative, civil, and criminal penalties, the imposition of remedial obligations, and the issuance of orders enjoining or limiting future operations, any of which could have a material adverse affect on our financial
condition. Legal requirements are sometimes unclear or subject to reinterpretation and may be frequently changed in response to economic or political conditions. As a result, it is hard to predict the ultimate cost of compliance with these
requirements or their affect on our interests and operations. In addition, existing laws or regulations, as currently interpreted or reinterpreted in the future, or future laws or regulations may have a material adverse affect on our financial
condition and results of operations.

The production, handling, storage, transportation and disposal of natural gas and oil, by-products of
natural gas and oil and other substances produced or used in connection with natural gas and oil production operations are regulated by laws and regulations focused on the protection of human health and the environment. Joint and several, strict
liability may be incurred without regard to fault, or the legality of the original conduct, under certain of these laws and regulations for the remediation of contaminated areas. Private parties, including the owners of properties located near our
storage facilities or through which our pipeline systems pass, also may have the right to pursue legal actions to enforce compliance, as well as seek damages for non-compliance with environmental laws and regulations or for personal injury or
property damage. Consequently, the discharge or release of natural gas, oil or other substances into the air, soil or water, even by predecessor operators, could subject us to liabilities arising from environmental cleanup and restoration costs,
claims made by neighboring landowners and other third parties for personal injury and property and natural resource damage, and fines or penalties for related violations of environmental laws or regulations. Moreover, the possibility exists that
stricter laws, regulations or enforcement policies could significantly increase our compliance costs and the cost of any remediation that may become necessary. We may not be able to recover some or any of these costs from insurance.

Our Australian operations are subject to unique risks relating to Aboriginal land claims and government licenses.

Our Australian operations could be affected by native title claims by Aboriginal groups. Australian law recognizes that in some instances native title,
that is the laws and customs of the Aboriginal inhabitants, has survived European settlement. Native title will only survive if it has not been extinguished. Native title may be extinguished by an Act of Government, such as the creation of a title
that is inconsistent with native title. This may include a grant of the right to exclusive possession through freehold title or lease. Native title may also be extinguished if the connection between the land and the group of Aboriginal people
claiming native title has been lost. Each authority to prospect, and license in areas in which we desire to engage in exploration or production activities must be examined individually in order to determine the validity of any native title claim. We
may be required to negotiate with any Aborigines who can make a valid claim to having ancestral ties to the areas in which we desire to engage in exploration or production activities. These negotiations could both delay the timing of our exploration
or production activities, as well as add an additional layer of cost or a requirement to share revenues if any Aboriginal claimants are proved to have native title rights in the exploration areas. Approximately 27.5% of our Gippsland Basin property
in Victoria may be subject to native title claims. We have been informed by the government of New South Wales that the proportion of land within PEL 238 in the Gunnedah Basin, New South Wales, which is potentially subject to native title claims,
cannot be readily determined.

The process of drilling for and producing natural gas and oil involves many operating risks that can cause substantial
losses, and we may not have enough insurance to cover these risks adequately.

The natural gas and oil business involves many
operating hazards, such as:



| |  |  | Well blowouts, fires and explosions;
| | - |  | ------------------------------------



| |  |  | Surface craterings and casing collapses;
| | - |  | ----------------------------------------



| |  |  | Uncontrollable flows of natural gas, oil or well fluids;
| | - |  | --------------------------------------------------------



| |  |  | Pipe and cement failures;
| | - |  | -------------------------



| |  |  | Formations with abnormal pressures;
| | - |  | -----------------------------------



| |  |  | Stuck drilling and service tools;
| | - |  | ---------------------------------



| |  |  | Pipeline ruptures or spills;
| | - |  | ----------------------------



| |  |  | Natural disasters; and
| | - |  | ----------------------



| |  |  | Releases of toxic natural gas.
| | - |  | ------------------------------

Any of these events could cause substantial losses to us as a result of:



| |  |  | Injury or death;
| | - |  | ----------------



| |  |  | Damage to and destruction of property, natural resources and equipment;
| | - |  | -----------------------------------------------------------------------



| |  |  | Pollution and other environmental damage;
| | - |  | -----------------------------------------



| |  |  | Regulatory investigations and penalties;
| | - |  | ----------------------------------------



| |  |  | Suspension of operations; and
| | - |  | -----------------------------



| |  |  | Repair and remediation costs.
| | - |  | -----------------------------

We
could also be responsible for environmental damage caused by previous owners of property that we purchase or lease. As a result, we may incur substantial liabilities to third parties or governmental entities. Although we maintain what we believe is
appropriate and customary insurance for these risks, the insurance may not be available or sufficient to cover all of these liabilities. If these liabilities are not covered by our insurance, paying them could reduce or eliminate the funds available
for exploration, development or acquisitions or result in the loss of our properties.

Approximately 66% of our revenues for the year ended
December 31, 2006 was from the production of wells located in our deep Bossier play in East Texas. Any disruption in production or our ability to process and sell our natural gas production from this area would have a material adverse effect on
our results of operations.

Production of the natural gas in the deep Bossier play in East Texas could unexpectedly be disrupted or
curtailed due to reservoir or mechanical problems. Additionally, a majority of our East Texas production is processed through two on-site processing facilities. If these facilities ceased to operate, were destroyed or otherwise needed replacement,
it could require 60 to 90 days to replace either one or both of these facilities. A 60 to 90 day curtailment of our East Texas production could reduce current revenues by an estimated $3.1 to $4.6 million, with a corresponding reduction in our cash
flow.

There are a limited number of natural gas purchasers and transporters in the Hilltop area of our deep Bossier play in East Texas. The loss of
our current purchaser and transporter and an inability to locate another purchaser and transporter would have a material adverse effect on our financial condition and results of operations.

There are a limited number of natural gas purchasers and transporters in the Hilltop area of the deep Bossier play in East Texas. During 2006, ETC Texas
Pipeline, Ltd. accounted for substantially all of our revenues from our deep Bossier play in East Texas. If ETC were to cease purchasing and transporting our natural gas and we were unable to contract with another purchaser and transporter, it would
have a material adverse effect on our financial condition and results of operations.

Our ability to market our natural gas and oil may be impaired
by capacity constraints on the gathering systems and pipelines that transport our natural gas and oil.

The availability of a ready
market for our natural gas production depends on the proximity of our reserves to and the capacity of natural gas gathering systems, pipelines and trucking or terminal facilities. We enter into agreements with companies that own pipelines used to
transport natural gas from the wellhead to contract destination. Those pipelines are limited in size and volume of natural gas flow. Should production begin, other outstanding contracts with other producers and developers could interfere with our
access to a natural gas line to deliver natural gas to the market. We do not own or operate any natural gas lines or distribution facilities. Further, interstate transportation and distribution of natural gas is regulated by the federal government
through the Federal Energy Regulatory Commission, or FERC. FERC sets rules and carries out administratively the oversight of interstate markets for natural gas and other energy policy. Among FERCs powers is the ability to dictate sale and
delivery of natural gas to any markets it oversees.

Additionally, state regulators have vast powers over sale, supply and delivery of natural gas and oil
within their state borders. While we do employ certain companies to represent our interests before state regulatory agencies, our interests may not receive favorable rulings from any state agency, or some future occurrence may drastically alter our
ability to enter into contracts or deliver natural gas to the market.

Competition in the natural gas and oil industry is intense. We are smaller and
have a more limited operating history than most of our competitors, and increased competitive pressure could adversely affect our results of operations.

We operate in a highly competitive environment. We compete with other natural gas and oil companies in all areas of our operations, including the acquisition of exploratory prospects and proven properties. Our
competitors include major integrated natural gas and oil companies, numerous independent natural gas and oil companies, individuals and drilling and income programs. Many of our competitors are large, well-established companies that have
substantially larger operating staffs and greater capital resources than we do and that, in many instances, have been engaged in the natural gas and oil business for a much longer time than we have. These companies may be able to pay more for
exploratory prospects and productive natural gas and oil properties and may be able to define, evaluate, bid for and purchase more properties and prospects than our financial and human resources permit. In addition, these companies may be able to
spend more on the existing and changing technologies that we believe are and will be increasingly important to the current and future success of natural gas and oil companies. Our ability to explore for natural gas and oil prospects and to acquire
additional properties in the future will depend on our ability to conduct our operations, to evaluate and select suitable properties and to consummate transactions in this highly competitive environment. Increased competitive pressure could
adversely affect our financial condition and results of operations.

Acquisition prospects are difficult to assess and may pose additional risks to
our operations.

Where appropriate, we may evaluate and pursue acquisition opportunities on terms our management considers
favorable. In particular, we expect to pursue acquisitions that have the potential to economically increase our natural gas and oil reserves. The successful acquisition of natural gas and oil properties requires an assessment of:



| |  |  | Recoverable reserves;
| | - |  | ---------------------



| |  |  | Exploration potential;
| | - |  | ----------------------



| |  |  | Future natural gas and oil prices;
| | - |  | ----------------------------------



| |  |  | Operating costs;
| | - |  | ----------------



| |  |  | Potential environmental and other liabilities; and
| | - |  | --------------------------------------------------



| |  |  | Permitting and other environmental authorizations required for our operations.
| | - |  | ------------------------------------------------------------------------------

In connection with such an assessment, we would expect to perform a review of the subject properties that we believe to be generally consistent with
industry practices. Nonetheless, the resulting conclusions are inexact and their accuracy inherently uncertain, and such an assessment may not reveal all existing or potential problems, nor will it necessarily permit a buyer to become sufficiently
familiar with the properties to fully assess their merits and deficiencies. Inspections may not always be performed on every platform or well, and structural and environmental problems are not necessarily observable even when an inspection is
undertaken. Future acquisitions could pose additional risks to our operations and financial results, including:



| |  |  | Problems integrating the purchased operations, personnel or technologies;
| | - |  | -------------------------------------------------------------------------



| |  |  | Unanticipated costs;
| | - |  | --------------------



| |  |  | Diversion of resources and management attention from our exploration business;
| | - |  | ------------------------------------------------------------------------------



| |  |  | Entry into regions or markets in which we have limited or no prior experience; and
| | - |  | ----------------------------------------------------------------------------------



| |  |  | Potential loss of key employees, particularly those of the acquired organization.
| | - |  | ---------------------------------------------------------------------------------

We cannot control the activities on properties we do not operate, which may affect the timing and success of our
future operations.

Other companies operate some of the properties in which we have an interest. As a result, we have a limited
ability to exercise influence over operations for these properties or their associated costs. Our dependence on the operator and other working interest owners for these projects and our limited ability to influence operations and associated costs
could have a material adverse affect on the realization of our targeted returns on capital in drilling or acquisition activities. The success and timing of our drilling and development activities on properties operated by others therefore depend
upon a number of factors that are outside of our control, including:



| |  |  | Timing and amount of capital expenditures;
| | - |  | ------------------------------------------



| |  |  | The operators expertise and financial resources;
| | - |  | -------------------------------------------------



| |  |  | Approval of other participants in drilling wells; and
| | - |  | -----------------------------------------------------



| |  |  | Selection of technology.
| | - |  | ------------------------

Technological
changes could affect our operations.

The natural gas and oil industry is characterized by rapid and significant technological
advancements and introductions of new products and services utilizing new technologies. As others use or develop new technologies, we may be placed at a competitive disadvantage, and competitive pressures may force us to implement such new
technologies at substantial costs. In addition, other natural gas and oil companies have greater financial, technical and personnel resources that may allow them to enjoy technological advantages and may in the future allow them to implement new
technologies before we can. We may be unable to respond to such competitive pressures and implement such technologies on a timely basis or at an acceptable cost. One or more of the technologies that we currently use or may implement in the future
may become obsolete.

Rapid growth could result in a strain on our resources.

Because of our size, our growth, if achieved, will likely place a significant strain on our financial, technical, operational and management resources.
The failure to continue to upgrade our technical, administrative, operating and financial control systems or the occurrence of unexpected expansion difficulties, including the recruitment and retention of experienced managers, geoscientists and
engineers, could have a material adverse effect on our business, financial condition and results of operations and our ability to timely execute our business plan.

Our ability to successfully execute and maximize our business plan is dependent on our ability to obtain adequate financing.

In order to maximize our business plan, we will need to raise at least $50.0 million of new capital to develop our properties in accordance with our business plan for the next twelve months. Our business plan, which includes participation
in 3-D seismic shoots, the drilling of exploration prospects and development projects and producing property acquisitions, has required and will continue to require substantial capital expenditures. We will require additional financing to fund our
planned growth. Our ability to raise additional capital will depend on the results of our operations and the status of various capital and industry markets at the time we seek such capital. Accordingly, we cannot be certain that additional financing
will be available to us on acceptable terms, if at all. In particular, the terms of our senior secured notes limit our ability to incur additional indebtedness. In the event additional capital resources are unavailable, we may be required to curtail
our exploration and development activities or be forced to sell some of our assets in an untimely fashion or on less than favorable terms.

Not
hedging our production may result in losses.

We currently do not hedge our natural gas and oil production. By not hedging our
production, we may be more adversely affected by declines in natural gas and oil prices than our competitors who engage in hedging



21

##### Table of Contents

##### Index to Financial Statements

arrangements. Further, should we elect to hedge in the future, such hedges may result in us receiving lower than current prevailing market prices and place
additional financial strains on us due to having to post margin calls on our hedges.

Exchange rate fluctuations subject us to unique risks.

As our Australian activities increase, we will be increasingly exposed to the impact of fluctuations in the exchange rate between
the Australian dollar and the U.S. dollar. We have only minimal exposure to Canadian currency fluctuations, as almost all of our current revenues and expenses are in U.S. dollars.

We depend on our key personnel, the loss of which could adversely affect our operations and financial performance.

We depend to a large extent on the services of a limited number of senior management personnel and directors. Particularly, the loss of the services of our chief executive officer and chief financial officer could
negatively impact our future operations. We have employment contracts with these key members of our senior management team; although, we do not maintain key-man life insurance on any of our senior management. We believe that our success is also
dependent on our ability to continue to retain the services of skilled technical personnel. Our inability to retain skilled technical personnel could have a material adverse effect on our business.

Our major shareholder may influence the activities and operations of certain jointly owned properties, which also could result in conflicts of interest.

As of December 31, 2006, Chesapeake Energy Corporation owned approximately 16.5% of our outstanding common shares. As a
result, Chesapeake is in a position to heavily influence the outcome of matters requiring a shareholder vote, including the election of directors, the adoption or amendment of provisions in our Amended and Restated Articles of Incorporation and
Bylaws and the approval of mergers and other significant corporate transactions. Their high level of ownership may also delay, defer or prevent a change in control of us and may adversely affect the voting and other rights of other shareholders.
Chesapeake has the right to have present an observer at our board of directors meetings.

Chesapeake and its subsidiaries are also engaged
in the natural gas and oil business. Although we have entered into a joint operating agreement with Chesapeake, it is possible that we may in some circumstances be in direct or indirect competition with Chesapeake, including competition with respect
to certain business strategies and transactions that we may propose to undertake. These conflicts of interest may have a material adverse affect our results of operations.

Some of our directors may not be subject to suit in the United States.

Two of our directors
reside in Canada. As a result, it may be difficult or impossible to effect service of process within the United States upon those directors, to bring suit against them in the United States or to enforce in the United States courts any judgment
obtained there against them predicated upon any civil liability provisions of the United States federal securities laws. Investors should not assume that Canadian courts (a) will enforce judgments of United States courts obtained in actions
against those directors predicated upon the civil liability provisions of the United States federal securities laws or the securities or blue sky laws of any state within the United States; or (b) will enforce, in original actions,
liabilities against those directors upon the United States federal securities laws or any such state securities or blue sky laws.

If we are unable
to meet the SECs requirements related to the assessment, attestation and effectiveness of our internal controls, we may suffer a loss of investor confidence, and the price of our common shares may be adversely affected.

Under the Securities Exchange Act, we will be required to include in our annual report a report on internal controls over financial reporting. This report
must state managements responsibility for establishing and



22

##### Table of Contents

##### Index to Financial Statements

maintaining an adequate internal control structure and procedures for financial reporting. The report must also contain an assessment as of the end of the
year of the effectiveness of those internal controls. The Exchange Act also requires our registered public accounting firm to test and report on the assessment made by management. These new rules will become effective for us for the year ending
December 31, 2007. In order to meet these requirements, we must document and test the effectiveness of our internal controls and then allow time for our registered public accounting firm to audit our internal control structure. The amount of
work required by us to prepare, maintain and test our internal control structure could be extensive. In the event that management is unable to complete its assessment of the effectiveness of our internal controls over financial reporting or our
auditors are unable to attest to managements assessment or do their own assessment, or if these internal controls are not effective, we might experience an adverse reaction in the financial marketplace due to a loss of investor confidence in
the reliability of our financial statements, which could negatively impact the market price of our common shares.

Risk Factors Related to Our Common
Shares

Our common share price has been and is likely to continue to be highly volatile.

The trading price of our common shares are subject to wide fluctuations in response to a variety of factors, including quarterly variations in operating
results, announcements of drilling and rig activity, economic conditions in the natural gas and oil industry, general economic conditions or other events or factors that our beyond our control. Information about the market price of our common shares
since trading commenced on the American Stock Exchange on January 5, 2006 is set forth in Item 5. Market for Registrants Common Equity and Related Shareholder Matters and Issuer Purchases of Equity SecuritiesMarket
Information.

In addition, the stock market in general and the market for natural gas and oil exploration companies in particular
have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating results or asset values of those companies. These broad market and industry factors may seriously impact the market price and
trading volume of our common shares regardless of our actual operating performance. In the past, following periods of volatility in the overall market and in the market price of a companys securities, securities class action litigation has
been instituted against these companies. If this type of litigation were instituted against us following a period of volatility in our common shares trading price, it could result in substantial costs and a diversion of our managements
attention and resources, which could have a materially adverse impact on our operations.

Future issuances of our common shares may adversely affect
the price of our common shares.

The future issuance of a substantial number of common shares into the public market, or the
perception that such issuance could occur, could adversely affect the prevailing market price of our common shares. A decline in the price of our common shares could make it more difficult to raise funds through future offerings of our common shares
or securities convertible into common shares.

Our ability to issue an unlimited number of our common shares under our articles of incorporation may
result in dilution or make it more difficult to effect a change in control of the company, which could adversely affect the price of our common shares.

Unlike most corporations formed in the United States, our Amended and Restated Articles of Incorporation chartered under the laws of the Province of Alberta, Canada permit the board of directors to issue an unlimited
number of new common shares without shareholder approval, subject only to the rules of the American Stock Exchange and the Toronto Stock Exchange or any future exchange on which our common shares trades. The issuance of a large number of common
shares could be effected by our directors to thwart a takeover attempt or offer for us by a third party, even if doing so would benefit our shareholders, which could result in the common shares being valued less in the market. The issuance, or the
threat of issuance, of a large number of common



23

##### Table of Contents

##### Index to Financial Statements

shares, at prices that are dilutive to the outstanding common shares could also result in the common shares being valued less in the market.

Failure to register our common shares that were sold in a November 2006 private placement could result in us being required to pay fees, which could be
significant.

On November 2006, we issued 25 million common shares for aggregate proceeds of $50.0 million. We are required to
use our reasonable commercial efforts to file a registration statement with the SEC covering the resale of the common shares within 120 days of the November 2006 closing date and to use our reasonable commercial efforts to cause the registration
statement to be declared effective within 180 days of the closing date. If a registration statement is not filed or declared effective within the time prescribed, we will be required to pay an amount in cash equal to 1.5% of the aggregate proceeds
per month, up to aggregate payments of 8% of the aggregate proceeds, or $4.0 million, until the registration statement is declared effective or the common shares become freely tradable pursuant to Rule 144(k).

Issuance of the common shares upon exercise of warrants and conversion of convertible debentures, together with additional issuances of common shares to purchasers
of our senior secured notes for no additional consideration, will dilute the ownership interest of existing shareholders and could adversely affect the market price of our common shares.

We are obligated to issue a substantial number of common shares upon exercise of outstanding common share purchase warrants and upon conversion of our
convertible debentures. In connection with the issuance of $73.0 million of senior secured notes in June and September 2005, we issued 6,697,125 common shares to the purchasers of our senior secured notes pursuant subscription receipts. Additionally
we have the right until June 2007 to issue an additional $10.0 million of senior secured notes, which would require the issuance of additional subscription rights. These issuances will dilute the ownership interest of existing shareholders. Any
sales in the public market of the common shares issuable upon such exercise of warrants, conversion, or issuance of additional common shares could adversely affect prevailing market prices of our common shares. In addition, the existence of these
warrants and convertible debentures may encourage short selling by market participants.

Production, Prices and Operating Expenses

The following table presents information regarding the production

Natural Gas and Oil Reserves

Our estimated total net proved reserves of natural gas and oil as of
December 31, 2006, and the present values of estimated future net revenues attributable to those reserves as of those dates, are presented in the following table. These estimates were prepared by Netherland, Sewell & Associates, Inc.,
independent reservoir engineers, and are part of their reserve reports on our natural gas and oil properties. Netherland, Sewell & Associates estimates were based on a review of geologic, economic, ownership and engineering data that
we provided. In estimating the reserve quantities that are economically recoverable, end-of-period natural gas and oil prices, held constant, were utilized. In accordance with SEC regulations, no price or cost escalation or reduction was considered.

In accordance with SEC regulations, estimates of our proved reserves and future net revenues are
made using sales prices estimated to be in effect as of the date of such reserve estimates and are held constant throughout the life of the properties, except to the extent a contract specifically provides for escalation. Estimated quantities of
proved reserves and future net revenues therefrom are affected by natural gas and oil prices, which have fluctuated significantly in recent years. Our estimated proved reserves have not been filed with or included in reports to any U.S. federal
agency.

Pricing Assumptions

SEC regulations require that the natural gas and oil prices used in Netherland, Sewell & Associates reserve reports are the period-end prices for natural gas and oil at December 31, 2006. These prices are held constant
in accordance with SEC guidelines for the life of the wells included in the reserve reports but are adjusted by lease for energy content, quality, transportation, compression and gathering fees, and regional price differentials. The pricing
assumptions are listed below:



|                                 |  |                         |      |             |   |      
|-------------------------------- |  | ----------------------- | ---- | ----------- | - | -----
|                                 |  | As of December 31, 2006
|                                 |  | Gas ($/MMBtu)           |      | Oil ($/Bbl)
|Production:                      |  |                         |      |             |   |      
|Hilltop Area, East Texas         |  | $                       | 5.42 |             | $ | 57.75
|Powder River Basin, Wyoming      |  | $                       | 4.46 |             | $ | 57.75
|Appalachian Basin, West Virginia |  | $                       | 5.63 |             | $ | 57.75
|Cherokee Basin, Kansas           |  | $                       | 5.64 |             | $ | 57.75

The weighted average natural gas and oil prices after basis adjustments used in our reserve
valuation as of December 31, 2006 were $56.59 per barrel and $4.76 per Mcf.

The prices used in calculating the estimated future net
revenue attributable to proved reserves do not reflect market prices for natural gas and oil production sold subsequent to December 31, 2006. There can be no assurance that all of the estimated proved reserves will be produced and sold at the
assumed prices. Accordingly, the foregoing prices should not be interpreted as a prediction of future prices.

|Item 7. | Managements Discussion and Analysis of Financial Condition and Results of Operations
|------- | -------------------------------------------------------------------------------------

The following discussion and analysis should be read in conjunction with accompanying consolidated financial statements and related notes included in
Item 8. Financial Statements and Supplementary Data, which begins on page F-1. 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, the impact of acquisitions, changes due to the adoption of SASB 123(R), estimates of proved reserves, potential failure to achieve production
from development projects, capital expenditures and other uncertainties, as well as those factors discussed below and elsewhere in this Form 10-K, 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 additional unconventional natural gas exploration in the deep Bossier
play in the Hilltop area in East Texas. Our primary CBM properties are in the United States in the Powder River Basin and in the Gunnedah and Gippsland Basins of Australia.

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 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.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------

All other significant accounting policies that we employ are presented in the notes to the consolidated
financial statements. The following discussion presents 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.

Full Cost Method of Accounting

We follow the full cost method of accounting for natural gas and oil operations, whereby all costs incurred in the acquisition, exploration and development of natural gas and oil reserves are initially capitalized
into cost centers on a country-by-country basis. Our current cost centers are located in the United States and Australia. Such costs include land acquisition costs, geological and geophysical expenditures, carrying charges on

##### Index to Financial Statements

non-producing properties, costs of drilling and overhead charges directly related to acquisition, exploration and development activities.

Costs capitalized, together with the costs of production equipment, are depleted and amortized on the unit-of-production method based on the estimated
net proved reserves, as determined by independent petroleum engineers. The percentage of total reserve volumes produced during the year is multiplied by the net capitalized investment plus future estimated development costs in those reserves.

Costs of acquiring and evaluating unproved properties are initially excluded from depletion calculations. These unevaluated properties are
assessed periodically to ascertain whether impairment has occurred. When proved reserves are assigned or the property is considered to be impaired, the cost of the property or the amount of the impairment is added to costs subject to depletion
calculations.

In applying the full cost method, we perform a quarterly ceiling test on the cost center properties whereby the net cost of
natural gas and oil properties, net of related deferred income taxes (net cost), is limited to the sum of the estimated future net revenues from proved reserves using prices in effect at the end of the period held constant, discounted at
10%, and the lower of cost or fair value of unproved properties, adjusted for related income tax effects (ceiling). If the net cost exceeds the ceiling, an impairment loss is recognized for the amount by which the net cost exceeds the
ceiling and is shown as a reduction in natural gas and oil properties and as additional depletion. Proceeds from a sale of natural gas and oil properties will be applied against capitalized costs, with no gain or loss recognized, unless such a sale
would significantly alter the rate of depletion or amortization.

Natural Gas and Oil Reserves

Nature of Critical Estimate Item.    Our estimate of proved reserves is based on the quantities of natural gas and oil which
geological and engineering data demonstrate, with reasonable certainty, to be recoverable in the future years from known reservoirs under existing economic and operating conditions. The accuracy of any reserve estimate is a function of the quality
of available data, engineering and geological interpretation, and judgment. For example, we must estimate the amount and timing of future operating costs, severance taxes, development costs, and workover costs, all of which may in fact vary
considerably from actual results. In addition, as prices and cost levels change from year to year, the economics of producing the reserves may change and therefore the estimate of proved reserves also may change. Any significant variance in these
assumptions could materially affect the estimated quantity and value of our reserves. Despite the inherent imprecision in these engineering estimates, our proved reserve volumes and values are used to calculate depletion and impairment provisions,
respectively.

Assumptions/Approach Used.    Units-of-production method to amortize our natural gas and oil
propertiesThe quantity of reserves could significantly impact our depletion expense. Any reduction in proved reserves without a corresponding reduction in capitalized costs will increase the depletion rate.

Ceiling Limitation TestThe full-cost method of accounting for natural gas and oil properties requires a quarterly calculation of a
limitation on capitalized costs, often referred to as a full-cost ceiling calculation. The ceiling is the discounted present value of our estimated total proved reserves using a 10% discount rate. To the extent that our capitalized costs (net of
accumulated depletion and deferred taxes) exceed the ceiling, the excess must be written off to expense. Once incurred, this impairment of natural gas and oil properties is not reversible at a later date even if natural gas and oil prices increase.
Impairments were required in the years ended December 31, 2006, and 2005. The calculation of our proved reserves could significantly impact our ceiling limitation used in determining whether an impairment of our capitalized costs is necessary.
The ceiling calculation dictates that prices and costs in effect as of the last day of the period are generally held constant indefinitely, but subsequent period end prices may be used if such prices would reduce the ceiling impairment. Therefore,
the future net revenues associated with the estimated proved reserves are not based on our assessment



32

##### Table of Contents

##### Index to Financial Statements

of future prices or costs, but rather are based on prices and costs in effect at the time of evaluation. The weighted average natural gas and oil prices
after basis adjustments used in the reserve valuations as of December 31, 2006 and 2005 were $54.85 per barrel and $6.11 per Mcf and $56.00 per barrel and $7.39 per Mcf, respectively.

Effect if different assumptions used.    Units-of-production method to amortize our natural gas and oil propertiesA 10%
increase in reserves would have decreased our depletion expense for the year ended December 31, 2006 by approximately 3%, while a 10% decrease in reserves would have increased our depletion expense by approximately 3% with an offsetting
adjustment to ceiling impairment.

The most likely factor to contribute to a ceiling test impairment is the price used to calculate the
reserve limitation threshold. A significant reduction in the prices at a future measurement date could trigger a full-cost ceiling impairment. A 10% decrease in prices would have resulted in the recognition of additional 2006 ceiling impairment
expense of approximately $14.4 million. A 10% increase in prices used would have reduced our 2006 ceiling impairment expense by approximately $14.8 million.

Unproved Property Impairment

Nature of Critical Estimate Item.    We have elected to use
the full-cost method to account for our natural gas and oil activities. Investments in unproved properties are not amortized until proved reserves associated with the properties can be determined or until impairment occurs. Unproved properties are
evaluated quarterly for impairment on a field basis. If the results of an assessment indicate that an unproved property is impaired, the amount of impairment is added to the proved natural gas and oil property costs to be amortized.

Assumptions/Approach Used.    At December 31, 2006, we had $81.5 million allocated to unproved United States property
costs which was comprised primarily of unevaluated acreage costs. The unproven property costs are evaluated by the technical team and management of whether the property has potential attributable reserves. Therefore, the assessment made by our
technical team and management of the potential reserves will determine whether costs are moved from the unproved category to the full-cost pool for depletion or whether an impairment is taken.

Effect if different assumptions used.    A 10% increase or decrease in the unproved property balance would have decreased or
increased our depletion expense by approximately 2% for the year ended December 31, 2006. A 10% decrease in unproved property balance would have increased our 2006 ceiling impairment expense by approximately $7.9 million.

Asset Retirement Obligation

Nature of
Critical Estimate Item.    We have certain obligations to remove tangible equipment and restore land at the end of natural gas and oil production operations. Our removal and restoration obligations are primarily associated
with plugging and abandoning wells. Under Financial Accounting Standards (SFAS) No. 143, Accounting for Asset Retirement Obligations, as discussed in Note 2 to our Consolidated Financial Statements, we estimate
asset retirement costs for all of our assets, inflation adjust those costs to the forecast abandonment date, discount that amount using a credit-adjusted-risk-free rate back to the date we acquired the asset or obligation to retire the asset and
record an ARO liability in that amount with a corresponding addition to our capitalized cost. We then accrete the liability quarterly using the period-end effective credit-adjusted-risk-free rate. As new wells are drilled or purchased, their initial
asset retirement cost and liability is calculated and recorded. Should either the estimated life or the estimated abandonment costs of a property change upon our quarterly review, a new calculation is performed using the same methodology of taking
the abandonment cost and inflating it forward to its abandonment date and then discounting it back to the present using our credit-adjusted-risk-free rate. The carrying value of the asset retirement obligation is adjusted to the newly calculated
value, with a corresponding offsetting adjustment to the asset retirement cost (included in the full-cost pool);

therefore, abandonment costs will almost always approximate the estimate. When wells are sold the related liability and asset costs are removed from the
balance sheet.

Assumptions/Approach Used.    Estimating the future asset removal costs is difficult and
requires management to make estimates and judgments because most of the removal obligations are many years in the future and contracts and regulations often have vague descriptions of what constitutes removal. Asset removal technologies and costs
are constantly changing, as are regulatory, political, environmental, safety and public relations considerations. Inherent in the estimate of the present value calculation of our AROs are numerous assumptions and judgments including the ultimate
settlement amounts, inflation factors, credit-adjusted-risk-free-rates, timing of settlement, and changes in the legal, regulatory, environmental and political environments.

Effect if different assumptions used.    Since there are so many variables in estimating AROs, we attempt to limit the impact
of managements judgment on certain of these variables by using input of qualified third parties. We engage independent petroleum engineers, who have consented to the use of their name and reports in this Form 10-K, to evaluate our properties
annually. We use the remaining estimated useful life from the year end reserve reports by our independent reserve engineer in estimating when abandonment could be expected for each property. We expect to see our calculations impacted significantly
if interest rates move from their current lows, as the credit-adjusted-risk-free rate is one of the variables used on a quarterly basis. Our technical team developed a standard cost estimate based on historical costs, industry quotes and depth of
wells. Unless we expect a wells plugging to be significantly different than a normal abandonment, we use this estimate. The resulting estimate, after application of a discount factor and some significant calculations, could differ from actual
results, despite all our efforts to make an accurate estimate.

Stock-Based Compensations

Effective January 1, 2003, we adopted the provisions of SFAS No. 123, Accounting for Stock-Based Compensation (SFAS
No. 123), using the prospective application method of SFAS No. 148, Accounting for Stock-Based CompensationTransition and Disclosure. This statement requires us to record compensation costs for options granted under our
stock option plan in accordance with the fair value method prescribed in SFAS No. 123.

Prior to January 1, 2003, we accounted
for stock options under the intrinsic value method of Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees and its related interpretations. No compensation expense was recognized for
stock options that had an exercise price equal to the market value of the underlying common stock on the date of grant. The fair values were determined by using the Black-Scholes-Merton valuation model.

Effective January 1, 2006, we adopted the fair value recognition provisions of SFAS 123(R), Share-Based Payment, using the
modified-prospective method. Under that method, compensation cost for 2006 includes: (a) compensation cost for all share-based payments granted prior to, but not yet vested as of, January 1, 2006, based on the grant date fair value
estimated in accordance with the original provisions of SFAS No. 123, and (b) compensation cost for all share-based payments granted subsequent to January 1, 2006, based on the grant-date fair value estimated in accordance with the
provisions of SFAS 123(R). Compensation expense is recognized on a straight-line basis over the options estimated lives for fixed awards with ratable vesting provisions.

Year Ended December 31, 2006 compared to Year Ended December 31, 2005

Revenues.    Substantially all of our revenues are derived from the production of natural gas in the United States. Revenues
were $26.8 million for the year ended December 31, 2006, down from $27.4 million for the year ended December 31, 2005. The decrease in revenues was the result of a 21% decrease in natural gas prices, which was partially offset by a 23%
increase in production.

Natural Gas and Oil Production and Average Sales Prices.    Natural gas represents
substantially all of our production. The table above sets forth production and sales information for the years ended December 31, 2006 and 2005.

Lease operating, transportation and selling expenses.    Lease operating, transportation and selling expenses were $8.6 million for the year ended December 31, 2006, up from $6.9
million for the year ended December 31, 2005. This increase was due to an increased number of producing wells. Our lease operating, transportation and selling expenses was $1.82 per Mcfe for the year ended December 31, 2006, compared to
$1.81 for the comparable period in 2005.

Depreciation, depletion and amortization.    Depreciation, depletion
and amortization was $16.3 million for the year ended December 31, 2006, up from $13.9 million for the year ended December 31, 2005. This increase primarily was attributable to new East Texas wells drilled and placed into production during
2006 and additional production from new CBM wells drilled in the Powder River Basin. The increase in DD&A expense was the result of a 23% increase in production, which was partially offset by an 5% decrease in the DD&A rate per unit of
production. The DD&A rate for the year ended December 31, 2006 was $3.44 per Mcfe, as compared to $3.63 for the comparable period in 2005.

Impairment of natural gas and oil properties.    Impairment of natural gas and oil properties was $56.3 million for the year ended December 31, 2006, compared to $8.7 million for the comparable period ended
2005. The 2006 year impairment was the result of net natural gas and oil property costs, as adjusted for related deferred income taxes and other adjustments, exceeding the sum of estimated future net revenues using post end of period weighted
average after basis adjustment prices held constant of $6.11 per Mcf for natural gas and $54.85 per barrel for oil, discounted at 10%, and United States unproven property at historical cost of $81.5 million, which was lower than the estimated fair
market value, as adjusted for related income taxes and other adjustments. The

2005 impairment is the result of net natural gas and oil property costs, as adjusted for related deferred income taxes, if any, and other adjustments,
exceeding the sum of estimated future net revenues using prices in effect at June 30, 2005, the date of the impairment, held constant at $5.32 per Mcf for natural gas and $52.33 per barrel for oil, discounted at 10%, and unproven properties at
historical costs of $93.3 million, which was lower than estimated fair market value, as adjusted for related deferred income taxes and other adjustments.

General and administrative.    We reported general and administrative expenses of $13.5 million for the year ended December 31, 2006, up from $8.7 million for the year ended
December 31, 2005. This increase in general and administrative expenses was primarily due to increases in staff, contract personnel and professional service charges and the recording of non-cash compensation expense due to the granting of stock
options. Stock-based compensation expense for 2006 pursuant to the SFAS 123(R), was $3.9 million, up from $2.3 million in 2005.

Litigation settlement expense.    The $2.4 million litigation settlement expense incurred in 2006 was primarily the result of a settlement payment regarding Western Gas Resources, Inc., et. al., of a
lawsuit involving a gas gathering agreement and its applicability to properties we exchanged in 2002.

Interest
expense.    We reported interest expense of $15.6 million for the year ended December 31, 2006, compared to $15.3 million for the year ended December 31, 2005. The increase in interest expense was the result of
higher average debt outstanding and higher interest rates, which were partially offset by a decline in financing cost amortization. Interest expense includes deferred financing cost amortization of $4.3 million for 2006, a decrease of $500,000 from
2005.

Year Ended December 31, 2005 compared to Year Ended December 31, 2004

Revenues.    Substantially all of our revenues are derived from the production of natural gas in the United States. We reported
revenues of $27.4 million for the year ended December 31, 2005, up from $6.1 million for the year ended December 31, 2004. This increase was attributable to the commencement of production of natural gas from our East Texas deep Bossier
Field in late 2004 and continued 2005 field development and related production increases coupled with additional production from new CBM wells drilled in the Powder River Basin. The acquisition of additional leasehold and working interests in East
Texas and the Powder River Basin from Geostar and higher prices for both natural gas and oil also contributed to the increase. Of the increase in revenues, 68% was attributed to higher production rates and 32% resulted from price increases.

Natural Gas and Oil Production and Average Sales Prices.    Natural gas represents substantially all of our
production. The table above sets forth production and sales information for the years ended December 31, 2005 and 2004.

Lease
operating, transportation and selling expenses.    Our lease operating, transportation and selling expenses were $6.9 million for the year ended December 31, 2005, up from $2.0 million for the year ended
December 31, 2004. This increase was due to higher production volumes and an increased number of producing wells, which was partially offset by a reduction in severance and property taxes. Our lease operating, transportation and selling
expenses per Mcfe were $1.81 during the year ended December 31, 2005, compared to $1.78 for the comparable period in 2004.

Depreciation, depletion and amortization.    Depreciation, depletion and amortization was $13.9 million for the year ended December 31, 2005, up from $3.2 million for the year ended December 31, 2004.
This increase was attributable to the commencement of natural gas production from the wells in East Texas and the acquisition of additional leasehold and working interest properties in East Texas and the Powder River Basin from Geostar. Of the
increase in DD&A expense, 73% was attributed to higher production rates and 27% was due to an increase in DD&A rate per unit. The DD&A rate for the year ended December 31, 2005 was $3.63 per Mcfe, as

##### Index to Financial Statements

compared to prior comparable period of $2.89 per Mcfe. The increase in the DD&A rate is primarily due to higher capital expenditures in East Texas.

Impairment of natural gas and oil properties.    Impairment of natural gas and oil properties was $8.7 million
for the year ended December 31, 2005, up from $6.3 million for 2004. The 2005 impairment is the result of net natural gas and oil property costs, as adjusted for related deferred income taxes and other adjustments, exceeding the sum of
estimated future net revenues using prices in effect at June 30, 2005, the date of the impairment, held constant at $5.32 per Mcf for natural gas and $52.33 per barrel for oil, discounted at 10%, and unproven properties at historical costs of
$93.3 million, which was lower than estimated fair market value, as adjusted for related deferred income taxes and other adjustments. The 2005 impairment was primarily the result of limited reserve additions during the current interim period and
higher costs incurred to drill and complete the East Texas wells.

General and administrative.    General and
administrative expenses were $8.7 million for the year ended December 31, 2005, up from $4.0 million for 2004. This increase in general and administrative expenses was primarily due to personnel increases, higher contract increases in staff,
contract personnel and professional service charges, costs associated with our Form S-1 Registration Statement and non-cash compensation expense due to the issuance of stock options. Stock-based compensation expense for 2005 was $2.3 million, up
from $1.4 million for 2004.

Interest expense.    Interest expense was $15.3 million for the year ended
December 31, 2005, up from $3.2 million for the year ended December 31, 2004. This increase was due to higher debt outstanding as a result of the sale in 2004 of $3.25 million of subordinated unsecured notes payable, the sale in 2004 of
$30.0 million of convertible senior debentures, the private placement in 2005 of $73.0 million of senior secured notes and the issuance in June 2005 of $32.0 million in unsecured subordinated notes to Geostar. Interest expense includes deferred
financing cost and debt discount amortization of $4.8 million for 2005, an increase of $4.0 million from 2004. In addition in June 2005, the senior unsecured notes were paid in full and a call premium of $622,000 was paid.

Liquidity and Capital Resources

At December 31, 2006, we had cash and cash equivalents of $40.7 million
and the ability to issue up to $10.0 million of additional senior secured notes. For the year ended December 31, 2006, we reported negative cash flow from operations of $1.3 million. Capital expenditures on natural gas and oil properties during
2006 totaled $55.7 million during the period.

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 2.5:1 and proved reserve PV10 to net senior secured debt coverage ratio of 1.0:1 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 or $6.00 per Mcf of natural gas and $40.00 per barrel of oil.

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, non-strategic asset sales, the issuance of additional senior secured notes, the issuance of subordinated notes or the issuance of



37

##### Index to Financial Statements

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 twelve months under our current business plan are estimated to total approximately $75.8 million, of which $54.5 million is estimated to be spent on our deep Bossier natural gas exploration and development
operations, $3.8 million is estimated to be spent on CBM projects in the United States and $17.5 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 twelve months. The additional financing funds will most likely include internally
generated cash flow, cash on hand, non-strategic asset sales, the issuance of additional senior secured notes, the issuance of subordinated notes or the issuance of additional equity. 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 17, 2006, the
Company closed 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. Net proceeds from this placement of $47.8 million, after
deducting placement fees and estimated expenses, is being 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 2007. A senior secured notes covenant restricts us from hedging more than 50% of future production.

At December 31, 2006, we were in compliance with all debt covenants.

Off Balance Sheet Arrangements

As of December 31, 2006, we had no off balance sheet arrangements. We
have no plans to enter into any off balance sheet arrangements in the foreseeable future.

Contractual Obligations

The following table summarizes our future contractual obligations under these
arrangements as of December 31, 2006:

We maintain a reserve for cost associated with the retirement of tangible long-lived assets. At December 31, 2006, our reserve for these obligations
totaled $4.2 million for which no contractual commitment exists. Information about this reserve is set forth in Footnote 9 Asset Retirement Obligation to our consolidated financial statements, which begins on page F-1.

We have employment contracts with our Chief Executive Officer and Chief Financial Officer, which obligate us to pay a specified level of salary, target
bonus and certain other payments and reimbursements to them during their employment and in the event of termination or change of control. Information about such payments is set forth in Item 11, Executive Compensation.

Commitments

In February 2007, we entered into a letter agreement with ETC Texas Pipeline, Ltd. that expands
our existing transportation and treating agreement to meet the future gathering, treating and transportation of natural gas produced and owned or controlled by us in the Hilltop area of East Texas. Under the letter agreement, ETC would construct a
gathering system sufficient to gather and treat up to 150 MMcfd, and we would deliver to ETC a minimum of approximately 135 Bcf over a 10-year period. Minimum annual sales over the 10-year period and fees for the gathering and treating of natural
gas are currently being negotiated.

In March 2007, we and our Australian joint venture partner in PEL 238 agreed to acquire outstanding
overriding royalty interests from several outside parties including directors of the joint venture partner. The terms of the agreements call for us to acquire and terminate our 35% share of a 4% overriding royalty interest in PEL 238 at a net cash
price of $2.5 million payable May 3, 2007. In addition, we are to reimburse our joint venture partner in cash for our 35% share of overriding royalty interests acquired and terminated by the joint venture partner using the joint venture
partners common stock as compensation. We expect our share of the costs associated with the acquisition and termination of overriding royalty interests acquired to be approximately $2.9 million due on or before May 2, 2007 or within three
days of notice from the joint venture partner if the shares are issued after May 2, 2007.

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. Based on our look-back analysis at June 30, 2006, no additional shares are due to Geostar at this time. We are still awaiting confirmation of
Geostars June 30, 2006 look-back review results.

As of the date of this filing, Geostar has neither responded to the
June 30, 2006 look-back analysis that we provided nor provided us an independent reserve analysis disputing our June 30, 2006 look-back analysis, which, as called for in the Purchase and Sale Agreement, would be averaged with our
independent reserve analysis for the purpose of determining how many, if any, shares would be due to Geostar.

On November 17, 2006 (Closing Date), we
issued to various subscribers 25 million of our common shares for $50.0 million (Aggregate Subscription Price). We have agreed to use our reasonable commercial efforts to file a registration statement covering the resale of the
common shares within 120 days of the Closing Date (the Filing Deadline) and to cause the registration statement to be declared effective within 180 days of the Closing Date (the Effectiveness Deadline). We agreed to cause the
registration statement to remain effective until the earlier of (i) 30 days after all the common shares have been sold under the registration statement, or (ii) one year from the Closing Date (the Effectiveness Period). If the
registration statement is not filed by the Filing Deadline, we agreed to pay to the subscribers an amount in cash equal to 1.5% of the Aggregate Subscription Price per month for the period between the Filing Deadline and the date that the
registration statement is filed. If the registration statement is not declared effective by the Effectiveness Deadline or shall cease to be effective for any period of time during the Effectiveness Period, we agreed to pay to the subscriber an
amount in cash equal to 1.5% of the Aggregate Subscription Price per month until such time as the registration statement is declared effective or the common shares become freely tradable pursuant to Rule 144(k), generally two years. Such amounts
will accrue daily and be paid monthly in arrears. The total penalty fee payable to the subscribers is limited to aggregate payments of 8% of the Aggregate Subscription Price or $4.0 million. We filed an S-3 Registration Statement on February 2,
2007 in regards to the common shares and are waiting for such to be declared effective once our Annual Report on Form 10-K is filed.

New Accounting Pronouncements

Accounting for Certain Hybrid Financial Instruments

In February 2006, the Financial Accounting Standards Board, or FASB, issued SFAS No. 155, Accounting for Certain Hybrid Instrumentsan
amendment of SFAS Statements 133 and 140,which is effective for all financial instruments acquired or issued after the beginning of an entitys first fiscal year that begins after September 15, 2006.The statement
improves financial reporting by eliminating the exemption from applying SFAS No. 133 to interests in securitized financial assets so that similar instruments are accounted for similarly regardless of the form of the instruments. The statement
also improves financial reporting by allowing a preparer to elect fair value measurement at acquisition, at issuance, or when a previously recognized financial instrument is subject to a re-measurement event, on an instrument-by-instrument basis, in
cases in which a derivative would otherwise have to be bifurcated, if the holder elects to account for the whole instrument on a fair value basis. The adoption of this statement is not expected to have a material impact on the Companys
consolidated financial position, results of operations, or cash flows.

Accounting for Uncertainty in Income Taxes

In June 2006, the FASB issued SFAS No. 48, Accounting for Uncertainty in Income Taxesan interpretation of SFAS
No. 109(FIN 48). This interpretation provides guidance for recognizing and measuring uncertain tax positions, as defined in SFAS No. 109, Accounting for Income Taxes. FIN 48 prescribes a threshold
condition that a tax position must meet for any of the benefit of the uncertain tax position to be recognized in the financial statements. Guidance is also provided regarding derecognition, classification and disclosure of these uncertain tax
positions. FIN 48 is effective for fiscal years beginning after December 15, 2006. The adoption of this Interpretation is not expected to have a material impact on the Companys consolidated financial position, results of operations, or
cash flows.

Guidance for Quantifying Financial Statement Misstatement

In September 2006, the SEC issued Staff Accounting Bulletin No. 108, Considering the Effects of Prior Year Misstatements when Quantifying
Misstatements in Current Year Financial Statements (SAB 108), which establishes an approach requiring the quantification of financial statement errors based on the effect of the error on each of the companys financial
statements and the related financial statement disclosures. This model is



40

##### Table of Contents

##### Index to Financial Statements

commonly referred to as a dual approach because it requires quantification of errors under both the iron curtain and
roll-over methods. The roll-over method focuses primarily on the impact of a misstatement on the income statement, including the reversing effect of prior year misstatements; however, its use can lead to the accumulation of
misstatements in the balance sheet. The iron curtain method focuses primarily on the effect of correcting the period end balance sheet with less emphasis on the reversing effects of prior year errors on the income statement. The Company currently
uses the iron curtain method for quantifying financial statement misstatements. The Company will initially apply the provisions of SAB 108 in connection with the preparation of the Companys annual financial statements for the year ending
December 31, 2006. The use of the dual approach did not have a material impact on the Companys consolidated financial position, results of operations, or cash flows.

Fair Value Measurements

In September 2006, the FASB issued SFAS No. 157,Fair Value Measurements (SFAS No. 157), which addresses how companies should measure fair value when companies are required to use a fair value measure for recognition or disclosure purposes under generally accepted
accounting principles (GAAP). As a result of SFAS No. 157, there is now a common definition of fair value to be used throughout GAAP. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after
November 15, 2007, and interim periods within those years. Although the disclosure requirements may be expanded where certain assets or liabilities are fair valued such as those related to stock compensation expense and hedging activities, the
Company does not expect the adoption of SFAS No. 157 to have a material impact on the Companys consolidated financial position, results of operations, or cash flows.



|Item 7A. | Quantitative and Qualitative Disclosure about Market Risk
|-------- | ---------------------------------------------------------

Commodity Price Risk

Our major commodity price risk exposure is to the prices received for our natural gas
production. Realized commodity prices received for our production are the spot prices applicable to natural gas in the region produced. Prices received for natural gas are volatile and unpredictable and are beyond our control. For the year ended
December 31, 2006, a 10% change in the prices received for natural gas production would have had an approximate $2.7 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 December 31, 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%. A 10% fluctuation in interest rates would have an approximate $391,000
impact on annual interest expense.

Currency Translation Risk

Our revenues and expenses and the majority of our capital expenditures are
primarily in U.S. dollars, thus limiting our exposure to currency translation risk. In 2006, our Australian activities consisted of capital expenditures totaling approximately $4.6 million. We have no plans in the foreseeable future to implement
hedges or financial instruments to manage international currency changes.

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

As required by SEC
Rule 13a-15(b), we have evaluated, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure
controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Our disclosure controls and procedures are designed to provide reasonable assurance that the information
required to be disclosed by the Company in reports that it files under the Exchange Act is accumulated and communicated to the Companys management, including our principal executive officer and principal financial officer, as appropriate, to
allow timely decisions regarding required disclosure and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Our principal executive officer and principal financial officer have
concluded that our current disclosure controls and procedures were effective as of December 31, 2006 at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over
financial reporting during the quarter ended December 31, 2006, that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Section 16 Reporting

Section 16(a) of the Exchange Act requires the Companys directors and
officers and persons who own more than 10% of a registered class of the Companys equity securities to file reports of ownership and changes in ownership with the SEC. Directors, officers, and greater-than-10% stockholders are required by SEC
regulations to furnish the Company with copies of all Section 16(a) forms they file. Based solely on review of information furnished to the Company, the Company believes that all Section 16(a) filing requirements applicable to its
directors, officers, and greater than 10% beneficial owners were complied with during the year ended December 31, 2006.

Code of Ethics

We adopted a Code of Ethics for senior management including our principal executive officer
and principal financial officer on December 15, 2005. A copy of our Code of Ethics was filed as an exhibit to our Registration Statement on Form S-1/A on December 22, 2005 and is also available on our internet website at
www.gastar.com. A copy of our Code of Ethics will be provided to any person without charge, upon request. Such requests should be directed to J. Russell Porter, President and Chief Executive Officer, 1331 Lamar Street, Suite 1080, Houston,
Texas 77010.

Shareholders or other interested parties may send communications to the Board of Directors by writing through the Secretary
of the Company at 1331 Lamar Street, Suite 1080, Houston, Texas 77010. The Secretary will forward to the directors all communications that, in his or her judgment, are appropriate for consideration by the directors. Comments or complaints relating
to our accounting, internal accounting controls or auditing matters will also be referred to members of the Audit Committee. The Audit Committee has procedures for (a) receipt, retention and treatment of complaints received by us regarding
accounting, internal accounting controls, or auditing matters and (b) the confidential, anonymous submission by our employees of concerns regarding questionable accounting or auditing matters.

Audit Committee

The Audit Committee currently is comprised of Messrs. Badwi (Chairman and financial
expert) and Crow. After reviewing the qualifications of the current members of the Audit Committee, the Board of Directors has determined that all current Audit Committee members are independent, as that concept is defined in
Section 10A of the Exchange Act, and the applicable rules of the American Stock Exchange. The Board of Directors also determined that all current Audit Committee members are financially literate and that Mr. Badwi is a financial
expert under the applicable rules of the Exchange Act. In accordance with its Terms of Reference, the Audit Committee examines and reviews on behalf of the Board of Directors, internal financial controls, financial and accounting policies and
practices, related party transactions and the form and content of financial reports and statements. The Audit Committee is responsible for the hiring, overseeing and terminating the independent accountants engaged to prepare any audit or issue any
audit report, and the work of the external auditors. The Chief Financial Officer attends the meetings of the Audit Committee by invitation.

On March 15, 2007, we notified the American Stock Exchange that we were not in compliance with the American Stock Exchange Company Guide Rule 121(B)(2)(a), which requires that each listed company must have, and certify that it has and
will continue to have, an audit committee of at least three independent members. As a result of an independent member of our Audit Committee not standing for reelection at our 2006 annual meeting of shareholders, the Audit Committee was left with
two independent members, one of whom remains designated as its financial expert.

Notwithstanding our current non-compliance with the American Stock Exchange rule regarding the number of
independent directors serving on the Audit Committee, at all times since January 4 2006, the date we first became listed and subject to the reporting requirements of the Exchange Act, as amended, our Audit Committee has consisted solely of
directors meeting the independence requirements of the American Stock Exchange and Section 10A of the Exchange Act.

We intend to
rectify this non-compliance as soon as practicable. We have instituted a search and expect to appoint a new director meeting the independence requirements to fill the vacancy on the Audit Committee prior to our annual meeting of shareholders
expected to be held in June 2007. As of the date of this report, we have not received any warning notice or notice of deficiency from the American Stock Exchange regarding this non-compliance.

Compensation Discussion and Analysis

The following Compensation Discussion and Analysis explains our
compensation objectives, philosophy and practices with respect to our chief executive officer and chief financial officer, who are referred to as Named Executive Officers. These individuals are our only executive officers.

Remuneration Committee

Executive compensation
is the responsibility of the Remuneration Committee. The Remuneration Committee operates under a written charter, or the Terms of Reference, adopted by the Board of Directors. Abby F. Badwi, Thomas L. Crow and Richard A. Kapuscinski are
members of the Board of Directors and members of the Remuneration Committee. Mr. Badwi is the Remuneration Committee Chairman. Each member of the Remuneration Committee qualifies as an independent director under the American Stock Exchange
listing standards and under the Exchange Act.

Compensation Consultants

The Remuneration Committee does not generally engage a compensation consultant to provide advice with respect to the amount or form of executive and
director compensation.

Role of Named Executive Officers in Establishing Compensation

The compensation of our Chief Executive Officer is determined by the Remuneration Committee. In determining the compensation of the Chief Executive
Officer, the Remuneration Committee takes into account the Chief Executive Officers responsibilities and performance, the Companys performance and the market in which the Company competes for executive talent. The Chief Executive Officer
does not attend any meetings related to his compensation. The compensation of our Chief Financial Officer is determined by the Remuneration Committee, after receiving the recommendations of the Chief Executive Officer. The recommendations are based
on an assessment of the Chief Financial Officers responsibilities and performance, the Companys performance and the market in which the Company competes for executive talent. The Chief Executive Officer attends those portions of the
meetings of the Remuneration Committee that are related to the Chief Financial Officers compensation.

Compensation Philosophy

Our compensation programs for Named Executive Officers are designed to achieve the following objectives:



| |  |  | Attract and retain highly talented individuals who will engage in behavior essential to our success;
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | Motivate and reward employee behavior that is critical to our success;
| | - |  | ----------------------------------------------------------------------

##### Table of Contents

##### Index to Financial Statements

| |  |  | Align the interests of our Named Executive Officers and our shareholders by motivating our Named Executive Officers to increase shareholder value and rewarding them
when shareholder value increases; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Balance annual cash and longer-term equity compensation.
| | - |  | --------------------------------------------------------

Benchmarking of Compensation

We believe that the compensation of the Named Executive Officers should be competitive
with the market in which we compete for executive talent. We gather information about this market by reviewing publicly available information about our competitors and by having discussions with individuals knowledgeable in recruiting executives in
the natural gas and oil industry.

Elements of Executive Compensation and Rationale

There are three key elements to our compensation: base salary, annual cash bonus awards and stock-based compensation. We believe that a combination of
these three elements balances rewards for current performance and longer term corporate objectives as measured, among other things, by stock performance. The terms of the Named Executive Officers employment, including their compensation and
other benefits, are set forth in employment contracts, described below.

The Company entered into employment agreements with J. Russell
Porter, our President and Chief Executive Officer, and Michael A. Gerlich, our Chief Financial Officer, effective February 24, 2005 and May 17, 2005, respectively. Each agreement renews annually unless terminated in accordance with the
provisions of the agreement. Each year the Remuneration Committee determines base salary, bonus and equity awards under each employment agreement, subject to certain provisions of the agreement.

Base Salary.Base pay represents the fixed element of the Named Executive Officers cash compensation. The base pay
reflects the individuals responsibilities, performance, skill set and the market value of that skill set. Base salaries for our Named Executive Officers are set at the beginning of each employment contract anniversary year.

Pursuant to the terms of Mr. Porters employment agreement, his base salary is initially set at $450,000 but may be adjusted upward or downward
at each years anniversary date at the discretion of the Remuneration Committee, except that in the event that the Remuneration Committee should determine to decrease Mr. Porters base salary, Mr. Porter has the right to be
advised of the basis for this decision and an opportunity to discuss the decision with the Remuneration Committee. In 2006, the Remuneration Committee made no changes to Mr. Porters base salary, based on its determination that the
existing base salary was competitive and appropriate in light of the overall level of corporate activity. Mr. Gerlichs annual compensation is set at $275,000 but may be adjusted upward, or downward, at each years anniversary date at
the discretion of the Remuneration Committee, except that in the case of a downward adjustment, such decrease can generally not be greater than ten percent (10%) per year and no more than twenty percent (20%) in total of his original
salary, unless the salary of the Chief Executive Officer has been reduced in certain specified amounts as well. In 2006, the Remuneration Committee made no changes to Mr. Gerlichs base salary, based on its determination that the existing
salary was competitive and appropriate in light of Mr. Gerlichs tenure with the Company and the overall level of corporate activity.

Annual Cash Bonus Awards.Our cash bonus awards provide our Named Executive Officers, as well as other employees, an opportunity to earn an annual cash bonus that is based on an evaluation of individual
performance and the performance of the Company. Annual cash bonuses are determined for our Named Executive Officers by the Remuneration Committee. In the case of the bonus for the Chief Financial Officer, the Chief Executive Officer makes a
recommendation to the Remuneration Committee with respect to the cash

##### Index to Financial Statements

bonus. Subject to the terms of the employment agreements relating to the Named Executive Officers, as described below, determinations relating to the amount
of the cash bonus are based on an evaluation of the Companys performance over the past year, the Named Executive Officers performance and the contributions of the Named Executive Officer to the Companys performance. Annual cash
bonus awards for our Named Executive Officers are determined at the end of each calendar year. Additional cash bonuses may be awarded to our Named Executive Officers during the year, as determined in the discretion of the Remuneration Committee.
Other than annual cash bonuses paid in 2006, no other cash bonuses were paid in 2006.

Mr. Porters employment contract provides
that he is entitled to an annual bonus in an amount which may take the form of cash compensation, the award of stock or stock options, royalty rights or otherwise and that he shall receive an annual cash bonus equal to at least 20% of his annual
base salary. The employment agreement further provides that the bonuses shall reflect not only the results of the Companys operations and business, but his contribution as President and Chief Executive Officer. For 2006, Mr. Porter was
paid a cash bonus of $225,000, or 50% of his base salary. His bonus for 2006 reflected the Remuneration Committees positive evaluation of Mr. Porters leadership during a year that we became a reporting company under United
States securities law, listed on the American Stock Exchange, as well as his success in completing the sale of a significant ownership position in the Company to an industry partner and in raising significant equity capital to finance our
expanded exploration activities in East Texas and Australia. No stock awards (other than stock option grants) or royalty awards were made to Mr. Porter in 2006.

Mr. Gerlichs employment contract provides that his first year bonus shall equal at least 20% of his gross salary. In future years, the Remuneration Committee may (but is not obligated) on a yearly basis, or
at such more frequent times as it may elect, award Mr. Gerlich a discretionary bonus or bonuses. Such bonuses may take the form of cash compensation, the award of stock or stock options, royalty rights or otherwise. A bonus reflects not only
the results of our operations and business, but of Mr. Gerlichs contribution to our operations and business. For 2006, Mr. Gerlich was paid a cash bonus of $96,000, or 35% of his base salary. His bonus reflected
Mr. Porters and the Remuneration Committees positive evaluation of Mr. Gerlichs leadership in establishing an autonomous Houston-based accounting and financial department, in transitioning us from a Canadian reporting
company to a United States reporting company listed on the American Stock Exchange, and his contributions in completing the sale of a significant ownership position to an industry partner, and in raising significant equity capital to finance our
expanded exploration activities in East Texas and Australia. No stock awards (other than stock option grants) or royalty awards were made to Mr. Gerlich in 2006.

Stock-based Compensation.We believe that equity compensation is the most effective means of linking compensation provided to our Named Executive Officers with increases in
shareholders value. Historically, we have used stock options as the equity compensation vehicle. Stock options are generally granted to new hires at the time of employment and to all others, including our Named Executive Officers, around the
time of our annual meeting of shareholders. Additional stock options may be granted during the year upon accomplishment of certain corporate goals or as an incentive tool. The Board of Directors has discretionary authority to determine vesting
periods of stock options. Typically, vesting periods are over a four year period beginning with 25% of the award vesting on the first anniversary of the date of the grant and an additional 25% vesting on each of the next three anniversary dates.
However, recent stock option grants to our Chief Executive Officer and certain technical managers vest over two years. Other stock options granted on the same date to the Chief Financial Officer and other employees vest over three years. The stock
option awards having shorter vesting periods were granted to provide additional shorter term incentive to our Named Executive Officers, certain technical and other employees. All stock options incorporate the following features:



| |  |  | Existing grants have a term of five or 10 years;
| | - |  | ------------------------------------------------



| |  |  | Grant prices is not less than the closing market price on the date immediately prior to the date of grant;
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | Grants do not include reload provisions;
| | - |  | ------------------------------------------



| |  |  | Repricing of options is prohibited, unless approved by the shareholders; and

| |  |  | Stock options vest over a period of time determined by the Board of Directors.
| | - |  | ------------------------------------------------------------------------------

We continue to use stock options as a long-term incentive vehicle because we believe:



| |  |  | Stock options align the interests of Named Executive Officers and our other employees with those of the shareholders;
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | Stock options foster the long-term perspective necessary for our success since the value received by the recipient from a stock option is based on the growth of the
stock price above the stock option exercise price; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Stock options help to provide a longer term balance to our overall compensation program.
| | - |  | ----------------------------------------------------------------------------------------

Pursuant to our stock option plans, the Board of Directors has designated the Remuneration Committee as the committee to administer the granting of stock
options. Stock option grants are determined by the Remuneration Committee, based on the recommendations of our Chief Executive Officer, except in the case of stock option grants awarded to the Chief Executive Officer. In determining the number of
stock options to be granted to Named Executive Officers, as well as other employees, the Remuneration Committee takes into account the Named Executive Officers position, the scope of his responsibilities, his ability to affect profits and
shareholder value and the individuals past and recent performance.

In 2006, Mr. Porter was granted stock options to acquire an
aggregate of 1,150,000 of our common shares, of which 150,000 stock options vest over four years and 1,000,000 stock options vest over two years. In the event of Mr. Porters termination, with or without cause, all unvested options will
vest and be exercisable for a period of 90 days from the date of termination. The 150,000 share grant dated April 5, 2006 was a part of a larger grant of stock options to employees designed to motivate and provide additional employee
incentives. The 1,000,000 share grant dated July 14, 2006 was in recognition of Mr. Porters leadership during a transition year, the completion of the sale of a significant ownership position in us to an industry partner and his
success during the year in raising significant equity capital to finance our expanded exploration activities in East Texas and Australia.

In 2006, Mr. Gerlich received three grants to acquire a total of 650,000 common shares. Of the 250,000 share grant dated January 16, 2006, 125,000 stock options were granted pursuant to his employment agreement and 125,000 stock
options were granted in recognition of our successful transition from a Canadian reporting company to a United States reporting company listed on the American Stock Exchange. The 100,000 share grant dated April 5, 2006 was a part of the larger
grant of stock option to employees described above. The 300,000 share grant dated July 14, 2006 was in recognition of Mr. Gerlichs successful establishment of an autonomous Houston-based accounting and financial department, his role
in our transition to a United States reporting company and his contributions to our capital raising program.

Perquisites.The Named Executive Officers are eligible to participate in the same comprehensive benefits as are offered to all full-time employees. Mr. Porters employment agreement provides that we
will pay or reimburse Mr. Porter up to $25,000 for his membership dues in such clubs and/or organizations as are reasonable and customary for a senior executive officer and will reimburse him for the cost of a yearly executive physical
examination and all required or recommended medical testing in connection with that yearly examination.

We paid, or reimbursed,
Mr. Porter a total of $95,892 during 2006. Of this amount, $19,962 related to the rental and related utility costs for an apartment in Houston, Texas; $41,264 related to the rental of an office in Miami, Florida (our Chief Executive
Officers city of residence); and $13,274 related to the use of a rental car while in Houston. The balance of $21,392 was related to airfare between Houston and Miami, club dues, an executive health physical examination and the Companys
contribution to Mr. Porters 401-K plan. Each of the items was incurred by or on behalf of Mr. Porter in the ordinary course of business or for his convenience and was considered reasonable and customary perquisites for a senior
executive officer.

Other than the comprehensive benefits offered to all full-time employees, Mr. Gerlich did not
receive any perquisites having a value over $10,000 in aggregate during 2006.

Post Termination or Change of Control Compensation and Benefits

Mr. Porters employment agreement provides that his employment shall terminate (i) without notice upon his death;
(ii) without notice upon his Disability, as defined in his employment contract; (iii) upon six months written notice to the Company by Mr. Porter for any or no reason, with or without cause; (iv) upon one
years written notice to Mr. Porter by the Company for any or no reason, with or without cause; or (v) by the Company without prior notice upon a showing of Reasonable Cause (as defined in his employment contract).

Mr. Gerlichs employment agreement provides that his employment shall terminate (i) without notice, upon his death;
(ii) without notice, upon his Disability, as defined in his employment contract; (iii) upon two months written notice to the Company by Mr. Gerlich for any or no reason, with or without cause; (iv) if there is a
change of control, as defined in his employment contract and that change in control results in a material change in the scope of Mr. Gerlichs duties and responsibilities such that he terminates his employment;
(v) upon two months written notice to Mr. Gerlich by the Company for any or no reason, with or without cause; (vi) or by the Company without prior notice, upon a showing of Reasonable Cause (as defined in his
employment contract).

Pursuant to the terms of their respective employment agreements, Messrs. Porter and Gerlich are entitled to receive
certain post termination compensation and benefits. These benefits were determined in the negotiations with each individual and were based on what the Board of Directors determined were elements of a competitive compensation arrangement at the time.
See Potential Payments upon Termination or Change of Control below.

On March 23, 2007, our Board of Directors approved a
change of control severance plan covering all employees, including the Named Executive Officers. The purpose of the severance plan is to promote stability and continuity of management and regular employees in the event a change of control
transaction should occur. A change of control is defined in the severance plan to mean (1) the consummation of a merger, consolidation, reorganization or other transaction whereby our shareholders retain less than 50% control, directly or
indirectly, of us or the surviving company, (2) our incumbent directors cease to constitute a majority of the board of directors or (3) a sale or other disposition of all or substantially all of our assets. The severance plan does not
change the specific, non-change of control severance payments in place under the existing employment contracts with our Named Executive Officers but does provide change of control severance benefits to the Named Executive Officers only if they are
greater than the severance benefits provided under the employment agreement. The change of control severance plan does not allow for any duplication of severance benefits.

For the Named Executive Officers, the severance plan provides that if a Named Executive Officers employment is terminated within two years
following a change of control for any reason other than (i) death, (ii) disability, (iii) by us for cause, or (iv) by the Named Executive Officer for other than a good reason, the Named Executive Officer
will receive a lump-sum payment equal to a multiple that is equal to the applicable severance period, as set forth in the change of control severance plan, times the sum of (1) his annual salary and (2) annual target bonus.

The following summarizes the severance periods and target bonus percentages for the Named Executive Officers:



|                        |  |                           |  |                        |  
|----------------------- |  | ------------------------- |  | ---------------------- | -
|Named Executive Officer |  | Severance Period in Years |  | TargetBonus Percentage |  
|Chief Executive Officer |  | 3.00                      |  | 50                     | %
|Chief Financial Officer |  | 2.50                      |  | 35                     | %

Additionally, during the applicable severance period, Named Executive Officers would receive
reimbursement for the cost of COBRA continuation health care coverage, less the amount charged at the time of termination to the employee for their medical coverage.

If the Named Executive Officer receives a payment or benefit that is subject to the golden parachute excise tax, the Named Executive Officer will receive an additional payment under the severance plan to
make him or her whole for that excise tax and any taxes on the additional parachute tax gross-up payment.

If the
individuals employment is terminated within six months prior to a change of control and it is reasonably shown to have been in connection with the change of control, then the change of control will be treated, with respect to that employee, as
having occurred prior to his or her termination.

|(1) | The fair values of stock option awards were determined by using the Black-Scholes-Merton valuation model as of the date of grant, as set forth in SFAS 123(R). See Note 10 to the
consolidated financial statements in this Form 10-K Equity Compensation Plans-Determining Fair Value under SFAS 123(R) for a discussion of assumptions made in the valuation of option awards. The amounts shown in this column represent the
stock-based compensation expense recognized by the Company during the year ended December 31, 2006 that was attributable to all stock options granted to the Named Executive Officer and outstanding during the year. Total fair value attributable
to stock options granted to Mr. Porter and Mr. Gerlich during 2006 as of the date of grant was $1,677,646 and $1,035,262 respectively.

Potential Payments Upon Termination or Change of Control

The table below discloses the amount of compensation
and/or other benefits due to Messrs. Gerlich and Porter in the event of their termination of employment, including, but not limited to, in connection with a change in control of the Company. The amounts shown assume that such termination was
effective as of December 31, 2006, and thus includes amounts earned through such time and are estimates of the amounts which would be paid out to the executives upon their respective termination. The actual amounts to be paid out can only be
determined at the time of such executives separation from the Company.

options. As of December 31, 2006, Mr. Gerlich had 62,500 stock options that were vested. The exercise prices of all of Mr. Gerlichs stock options were greater than the market price of our common shares on December 31, 2006.



|(2) | Mr. Porters employment contract does not specifically address a change of control situation. It does however provide that he may terminate his own employment for any or
no reason, with or without cause, upon six months written notice. In such case, his severance would be determined as provided in footnote 1 above.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Mr. Gerlichs employment contract provides that if a change in control (as defined in his employment agreement) results in material change in the scope of his duties and responsibilities, he will be entitled
to receive a severance payment in the form and amount as determined in footnote 1 above.



|(3) | Per their respective employment agreements, we are not obligated to pay any amounts to Mr. Gerlich or Mr. Porter, other than accrued and unused vacation days and their
pro-rata base salary through the date of his termination of employment, as a result of a termination for reasonable cause (as defined in their respective employment agreements).
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(4) | Per their respective employment agreements, if Mr. Porters or Mr. Gerlichs employment terminates due to death, his eligible beneficiary will be entitled to
receive his severance payment over the severance period described in footnote 1 above. If Mr. Porters or Mr. Gerlichs employment terminates due to a disability (as defined in their respective employment agreements), he shall be
entitled to receive a severance payment in the form and amount as determined in footnote 1 above.

Mr. Gerlichs

us for a period of two years following his termination of employment.

confidentiality provision applicable both during the term of his employment and following his termination of employment. Pursuant to the confidentiality provision, Mr. Porter agrees to hold in confidence and not disclose any confidential
information about our business, except as required in the ordinary course of performing his employment duties with us. A breach of this confidentiality provision could result in a reasonable cause termination. Mr. Porters employment

|(1) | The fair values of stock option awards were determined in accordance with SFAS 123(R) by using the Black-Scholes-Merton valuation model as of the date of grant. See Equity
Compensation Plans-Determining Fair Value under SFAS 123(R) in Note 10 to the consolidated financial statements in this Form 10-K for a discussion of assumptions made in the valuation of option awards. The amounts shown in this column
represent the stock-based compensation expense recognized by the Company during the year ended December 31, 2006 that was attributable to stock options granted to directors. Total fair value attributable to stock options granted to
Mr. Badwi, Crow and Kapuscinski during 2006 as of the date of grant was $640,000, $384,000 and $384,000, respectively. During 2006, Messrs. Badwi, Crow and Kapuscinski were awarded stock options to purchase 500,000, 300,000 and 300,000 common
shares, respectively. We have granted to our directors stock options in addition to their specified compensation to be paid as directors. These grants are, in part, to compensate our directors for the stricter regulatory role in which they have to
operate and to provide them with incentives to remain as a director by offering them a long term stake in our potential future value. In determining the number of stock options granted, consideration was given to the number of stock options granted
to the Named Executive Officer, as well as to management. Additional consideration was given to Mr. Badwi, who serves as the chairman of the Audit Committee, as well as other committees of the Board of Directors.

|(2) | As permitted by the rules promulgated by the SEC, no amounts are shown with respect to perquisites and personal benefits for a director if the total value of all perquisites and
personal benefits is less than $10,000.

|(3) | Mr. Robinson resigned as Chairman of the Board effective August 1, 2006. During 2006, while serving Chairman, he waived receipt of his directors fees and received no
stock option grants.

|(4) | Mr. Heysel did not stand for reelection at the Annual Meeting of Shareholders held June 1, 2006. During 2006, while serving as a director, he did not receive any
directors fees for meeting attendance and received no stock option grants.

|Item 12. | Security Ownership of Certain Beneficial Owners and Management and Related Shareholder Matters
|-------- | ----------------------------------------------------------------------------------------------

Securities Authorized for Issuance under Equity Compensation Plans

2002 Stock Option Plan

Our 2002 Stock Option Plan was approved and ratified by our shareholders on July 5, 2002. The 2002 Stock Option Plan superseded and replaced our
prior stock-based compensation plans. Unexercised stock options granted under our prior stock option plans that had not expired or been cancelled on the effective date of the 2002 Stock Option Plan were ratified and confirmed as included under the
2002 Plan. Consequently, all currently outstanding stock options are subject to the terms of the 2002 Stock Option Plan. In April 2004, our Board of Directors amended the provisions of the 2002 Stock Option Plan to specifically incorporate a
provision to provide for stock options to be exercised on a cashless basis whereby we issue the optionee the number of common shares equal to the stock option exercised, less the number of common shares which when multiplied by the market price at
the date of exercise equals the aggregate exercise price for all of the common shares exercised.

We have authorized to issue, and have
reserved, a maximum of 25.0 million common shares for awards under the 2002 Stock Option Plan. If any stock option granted under the 2002 Stock Option Plan expires or terminates for any reason in accordance with its terms without being
exercised, the unpurchased shares subject to that stock option will become available for other option grants under the 2002 Stock Option Plan.

The 2002 Stock Option Plan is administered by our Remuneration Committee. Pursuant to the 2002 Stock Option Plan, our Remuneration Committee may allocate non-transferable options to purchase common shares to directors, officers, employees
and consultants of Gastar and its subsidiaries. At the time of granting options under the 2002 Stock Option Plan, the aggregate number of common shares underlying all options granted and the aggregate number of common shares underlying the options
granted to each individual may not exceed the maximum number permitted by any stock exchange on which our common shares are listed or by any other regulatory body having jurisdiction. Options issued pursuant to the 2002 Stock Option Plan have an
exercise price determined by the Remuneration Committee, but that exercise price cannot be less than the price permitted by any stock exchange on which our common shares are then listed.

As of December 31, 2006, we had options outstanding to purchase 10,472,750 common shares pursuant to the 2002 Stock Option Plan, 2,931,500 common
shares of which are vested but have not been exercised.

2006 Gastar Long-Term Stock Incentive Plan

On June 1, 2006, at the 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 issuance of stock options, common shares and stock appreciation rights to directors, officers and employees of the Company and its subsidiaries to purchase a maximum of 5.0 million common shares.
Stock options may be exercised on a cash or cashless basis. The contractual life and vesting period for stock options granted will be determined at the time stock options are granted. If any stock option granted under the 2006 Gastar Long-Term Stock
Incentive Plan expires or terminates for any reason in accordance with the its terms without being exercised, the unpurchased shares subject to that stock option will become available for other option grants under the 2006 Gastar Long-Term Stock
Incentive Plan.

The 2006 Gastar Long-Term Stock Incentive Plan is administered by our Remuneration Committee. Pursuant to the 2006 Gastar
Long-Term Stock Incentive Plan, our Remuneration Committee may allocate

non-transferable options to purchase common shares to directors, officers, employees and consultants of Gastar and its subsidiaries. At the time of granting
stock options under the 2006 Gastar Long-Term Stock Incentive Plan, the aggregate number of common shares underlying all stock options granted and the aggregate number of common shares underlying the options granted to each individual may not exceed
the maximum number permitted by any stock exchange on which our common shares are listed or by any other regulatory body having jurisdiction. Options issued pursuant to the 2006 Gastar Long-Term Stock Incentive Plan have an exercise price determined
by the Remuneration Committee, but that exercise price cannot be less than the price permitted by any stock exchange on which our common shares are then listed.

As of December 31, 2006, no stock options had been granted under the 2006 Gastar Long-Term Stock Incentive Plan.

|Item 13. | Certain Relationships, Related Transactions, and Director Independence
|-------- | ----------------------------------------------------------------------

Information concerning related party transactions is set forth in Footnote 13 Related Party Transactions to our consolidated financial
statements, which begins on page F-1.

Our written policy or procedure for the review, approval or ratification of related party
transactions is set forth in the Terms of Reference for the Audit Committee. The Audit Committee reviews and approves all related party transactions. In the course of its review, the Audit Committee considers the nature of the transactions and the
costs to be incurred by us or payments to us; an analysis of the costs and benefits associated with the transaction and a comparison of comparable or alternative goods or services that are available to us from unrelated parties; the business
advantage we would gain by engaging in the transaction; and an analysis of the significance of the transaction to us and to the related party. As a matter of course, any Audit Committee member that cannot be viewed as independent will withhold his
vote, declaring his interest in the transaction. A vote of a majority of the remaining members is required to approve a related party transaction.

Our Board of Directors is comprised of four members whose names and committee memberships are set forth below. Our Board of Directors has determined that a majority of the members of the Board of Directors have no material relationship with
the Company (either directly or as partners, shareholders or officers of an organization that has a relationship with the Company) and are independent within the meaning of the AMEX director independence standards. J. Russell Porter, as our
President and Chief Executive Officer, is not considered to be independent. Furthermore, the Board has determined that each of the members of the Audit Committee, the Remuneration Committee, the Nomination and the Governance Committee has no
material relationship to the Company (either directly or as a partner, shareholder or officer of an organization that has a relationship with the Company) and is independent within the meaning of the AMEX director independence standards.

Report of Independent Registered Public Accounting Firm

Board of Directors and Shareholders

Gastar Exploration Ltd.

Houston, Texas

We have audited the accompanying consolidated balance sheets of Gastar Exploration Ltd. and subsidiaries as of December 31, 2006 and 2005, and the
related consolidated statements of operations, shareholders equity and cash flows for each of the two years in the period ended December 31, 2006. These financial statements are the responsibility of the Companys management. Our
responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the
standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatements. The
Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis of designing audit procedures that
are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Companys internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining,
on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to
above present fairly, in all material respects, the financial position of Gastar Exploration Ltd. and subsidiaries at December 31, 2006 and 2005, and the results of its operations and its cash flows for each of the two years in the period ended
December 31, 2006, in conformity with accounting principles generally accepted in the United States of America.

As more fully
described in Note 2 to the consolidated financial statements, effective January 1, 2006, the Company adopted the provisions of SFAS 123(R), Share-Based Payment.

GASTAR EXPLORATION LTD. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Description of Business

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 are additionally pursuing
unconventional natural gas exploration in the deep Bossier play in the Hilltop area in East Texas. Our primary CBM properties are in the United States in the Powder River Basin in Wyoming and in the Gunnedah and Gippsland Basins of Australia.

2. Summary of Significant Accounting Policies

The consolidated financial statements of the Company are stated 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 (See Supplemental Oil and Gas Disclosures).

Principles of Consolidation

The 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 and are Gastar Exploration USA, Inc., Gastar Exploration Texas,
Inc., Gastar Exploration Texas LP, Gastar Exploration Texas LLC, Gastar Exploration New South Wales, Inc. and Gastar Exploration Victoria, Inc. All significant intercompany accounts and transactions have been eliminated in consolidation.

Foreign Currency Translation and Exchange

A majority of the Companys operations are conducted by its U.S. subsidiaries in U.S. dollars. The operations outside of the U.S. are primarily natural gas and oil property development in Australia, which are conducted in Australian
dollars (AUD$). Our Australian properties represent CBM wells that are in the exploration or pre-production stage. We currently have no commercial production operations in Australia. Limited operations are conducted in Canadian dollars
(CDN$). Foreign operations are translated using rates in effect at the period end for the balance sheet, while the income statement is translated at the average rates prevailing during the period. Adjustments resulting from financial
statement translations are included in cumulative translation adjustments in Accumulated Other Comprehensive Loss and as a component of shareholders equity.

Foreign currency balances and non-monetary assets and liabilities are translated at the rates of exchange on the particular transaction date. Monetary assets and liabilities denominated in foreign currencies that
remain outstanding at the balance sheet date are translated at period end exchange rates with resulting gains (losses) being recognized in the period. The accounts of all active subsidiaries are maintained in U.S. dollars. Translation gains and
losses recorded on investments in subsidiaries that are of a permanent nature are not tax effected.

Cash Equivalents

Cash equivalents include short-term investments, such as money market deposits or highly liquid debt instruments, with a maturity of three months or less when purchased, amounted to $33.9 and $54.0 million as of
December 31, 2006 and 2005, respectively. The Company maintains its cash in bank deposit accounts, which, at times, may exceed federally insured limits. The Company has not experienced any losses in such accounts and believes it is not exposed
to any significant risk of loss.

Accounts Receivable

At December 31, 2006 and 2005, the Company had no allowance for doubtful accounts recorded. The allowance for doubtful accounts is determined based on a review of Company receivables. Receivable accounts are
charged off when collection efforts have failed and the account is deemed uncollectible.

Deferred Financing Costs and Debt Discount

Deferred financing costs include costs of debt financings undertaken by the Company including commissions, legal fees, value
attributed to warrants issued in conjunction with a financing and other direct costs of the financing. Using the effective interest method, the deferred financing costs are amortized over the term of the related debt instrument.

Debt discount is amortized over the term of the related debt utilizing the effective interest method.

Natural Gas and Oil Properties

The Company
follows the full cost method of accounting for natural gas and oil operations, whereby all costs incurred in the acquisition, exploration and development of natural gas and oil reserves are initially capitalized into cost centers on a
country-by-country basis. The Companys current cost centers are located in the United States and Australia. Such costs include land acquisition costs, geological and geophysical expenditures, carrying charges on non-producing properties, costs
of drilling and overhead charges directly related to acquisition, exploration and development activities.

Costs capitalized, together with
the costs of production equipment, are depleted and amortized on the unit-of-production method based on the estimated net proved reserves, as determined by independent petroleum engineers. The percentage of total reserve volumes produced during the
year is multiplied by the net capitalized investment plus future estimated development costs in those reserves.

Costs of acquiring and
evaluating unproved properties are initially excluded from depletion calculations. These unevaluated properties are assessed periodically to ascertain whether impairment has occurred. When proved reserves are assigned or the property is considered
to be impaired, the cost of the property or the amount of the impairment is added to costs subject to depletion calculations.

In applying
the full cost method, the Company performs a quarterly ceiling test on the cost center properties whereby the net cost of natural gas and oil properties, net of related deferred income taxes (net cost), is limited to the sum of the
estimated future net revenues from proved reserves using prices in effect at the end of the period held constant, discounted at 10%, and the lower of cost or fair value of unproved properties, adjusted for related income tax effects
(ceiling). If the net cost exceeds the ceiling, an impairment loss is recognized for the amount by which the net cost exceeds the ceiling and is shown as a reduction in natural gas and oil properties and as additional depletion. Proceeds
from a sale of natural gas and oil properties will be applied against capitalized costs, with no gain or loss recognized, unless such a sale would significantly alter the rate of depletion or amortization.

Furniture and Equipment

Furniture and equipment are recorded at historical cost and are depreciated over their estimated useful lives, which ranges from three to seven years on a straight-line basis.

Fair Value of Financial Instruments

The
carrying amounts of the Companys short-term financial instruments, including cash equivalents, trade accounts receivable and trade accounts payable, approximate their fair values based on the short maturities of those instruments. The
Companys Senior Secured Notes are variable rate debt and, as such, approximates fair value, as interest rates are variable based on prevailing market rates. The Companys 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.

Revenue Recognition

The Company records revenues from the sale of natural gas and oil when
delivery to the customer has occurred and title has transferred. This recording of revenues occurs when natural gas or oil has been delivered to a pipeline or a tank lifting has occurred. Revenues from natural gas and oil production are recorded
using the sales method. Under this method, revenues are recorded based on the Companys net revenue interest, as delivered. The Company had no material gas imbalances at December 31, 2006.

Asset Retirement Obligation

The Company
accounts for its asset retirement obligations in accordance with SFAS No. 143, Accounting for Asset Retirement Obligations (SFAS No. 143). Asset retirement costs and liabilities associated with future site
restoration and abandonment of tangible long-lived assets are initially measured at a fair value which approximates the cost a third party would incur in performing the tasks necessary to retire such assets. The fair value is recognized in the
financial statements as the present value of expected future cash expenditures for site restoration and abandonment. Subsequent to the initial measurement, the effect of the passage of time on the liability for the asset retirement obligation
(accretion expense) and the amortization of the asset retirement cost are recognized in the results of operations.

Mineral Resource Properties

Mineral resource properties are properties that may hold mineral deposits of rutile (titanium dioxide), zircon (zirconium silicate)
and other resource minerals. All exploration and related direct and indirect overhead expenditures for mineral resources are expensed. Capitalized acquisition costs, if any, are written off when the decision to abandon the mineral resource property
is made.

Deferred Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing
assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary
differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized as income in the period that

includes the enactment date. The Company has established a valuation reserve to offset its net deferred tax asset since, on a more likely than not basis,
such benefits are not considered recoverable at this time.

Loss per Share

In accordance with the provisions of SFAS No. 128, Earnings per Share (SFAS No. 128), 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 outstanding plus the incremental effect of the
assumed issuance of common shares for all potentially dilutive securities. Diluted per share amounts reflect the potential dilution that could occur if securities or other contracts to issue common shares were exercised or converted to common
shares. The treasury stock method is used to determine the dilutive effect of stock options and warrants and the as if converted method for the Senior Convertible Debentures.

Stock-Based Compensation

The Company reports compensation expense for stock options granted
to officers, directors and employees using the fair value method. Compensation costs are recorded over the requisite service period, which approximates the vesting period.

Prior to January 1, 2003, the Company accounted for stock options under the intrinsic value method of Accounting Principles Board (APB)
Opinion No. 25, Accounting for Stock Issued to Employees and its related interpretations. No compensation expense was recognized for stock options that had an exercise price equal to the market value of the underlying common stock
on the date of grant. The fair values were determined by using the Black-Scholes-Merton valuation model.

Effective January 1, 2003,
the Company adopted the provisions of SFAS No. 123, Accounting for Stock-Based Compensation (SFAS No. 123), using the prospective application method of SFAS No. 148, Accounting for Stock-Based
Compensation  Transition and Disclosure. This statement requires the Company to record compensation costs for options granted under the Companys stock option plan in accordance with the fair value method prescribed in SFAS
No. 123.

Effective January 1, 2006, the Company adopted the fair value recognition provisions of the Financial Accounting
Standards Board (FASB) SFAS 123(R), Share-Based Payment, using the modified-prospective method. Under that method, compensation cost for 2006 includes: (a) compensation cost for all share-based payments granted prior to, but not yet
vested as of, January 1, 2006, based on the grant date fair value estimated in accordance with the original provisions of SFAS No. 123, and (b) compensation cost for all share-based payments granted subsequent to January 1, 2006,
based on the grant-date fair value estimated in accordance with the provisions of SFAS 123(R). Compensation expense is recognized on a straight-line basis over the requisite service period, which is equivalent to the vesting period. The adoption of
SFAS 123(R) had an immaterial effect on 2006 financial results.

Joint Venture Operation

The majority of the Companys natural gas and oil exploration activities are conducted jointly with others. These consolidated financial statements
reflect only the Companys proportionate interest in such activities.

Industry Segment and Geographic Information

The Company operates in one industry segment, which is the exploration, development and production of natural gas and oil. The Companys operational
activities are conducted in the United States and Australia with only the United States currently having revenue generating operating results.

Treasury Stock

The Companys common shares are without par value. Treasury stock purchases are recorded at cost
as a reduction to common stock. Common shares are cancelled upon repurchase.

Reclassifications

Certain information provided for the prior years have been reclassified to conform to the current year presentation adopted in 2006.

New Accounting Pronouncements

Accounting
for Certain Hybrid Financial Instruments.    In February 2006, FASB issued SFAS No. 155, Accounting for Certain Hybrid Instrumentsan amendment of SFAS Statements 133 and 140,which is effective
for all financial instruments acquired or issued after the beginning of an entitys first fiscal year that begins after September 15, 2006.The statement improves financial reporting by eliminating the exemption from applying SFAS
No. 133 to interests in securitized financial assets so that similar instruments are accounted for similarly regardless of the form of the instruments. The statement also improves financial reporting by allowing a preparer to elect fair value
measurement at acquisition, at issuance, or when a previously recognized financial instrument is subject to a re-measurement event, on an instrument-by-instrument basis, in cases in which a derivative would otherwise have to be bifurcated, if the
holder elects to account for the whole instrument on a fair value basis. The adoption of this statement is not expected to have a material impact on the Companys financial statements.

Accounting for Uncertainty in Income Taxes.In June 2006, the FASB issued SFAS Interpretation No. 48, Accounting
for Uncertainty in Income Taxesan interpretation of SFAS Statement No. 109(FIN 48). This interpretation provides guidance for recognizing and measuring uncertain tax positions, as defined in SFAS

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



No. 109, Accounting for Income Taxes. FIN 48 prescribes a threshold condition that a tax position must meet for any of the benefit of the
uncertain tax position to be recognized in the financial statements. Guidance is also provided regarding de-recognition, classification and disclosure of these uncertain tax positions. FIN 48 is effective for fiscal years beginning after
December 15, 2006. The adoption of this Interpretation is not expected to have a material impact on the Companys financial statements.

Guidance for Quantifying Financial Statement Misstatement.    In September 2006, the SEC issued Staff Accounting Bulletin No. 108, Considering the Effects of Prior Year Misstatements when Quantifying
Misstatements in Current Year Financial Statements (SAB 108), which establishes an approach requiring the quantification of financial statement errors based on the effect of the error on each of the companys financial
statements and the related financial statement disclosures. This model is commonly referred to as a dual approach because it requires quantification of errors under both the iron curtain and roll-over
methods. The roll-over method focuses primarily on the impact of a misstatement on the income statement, including the reversing effect of prior year misstatements; however, its use can lead to the accumulation of misstatements in the balance
sheet. The iron curtain method focuses primarily on the effect of correcting the period end balance sheet with less emphasis on the reversing effects of prior year errors on the income statement. The Company has applied the provisions of SAB 108 in
connection with the preparation of the Companys annual financial statements for the year ending December 31, 2006. The use of the dual approach did not have a material impact on the Companys financial statements.

Fair Value Measurements.    In September 2006, the FASB issued SFAS No. 157,Fair Value Measurements
(SFAS No. 157), which addresses how companies should measure fair value when companies are required to use a fair value measure for recognition or disclosure purposes under generally accepted accounting principles
(GAAP). As a result of SFAS No. 157, there is now a common definition of fair value to be used throughout GAAP. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007,
and interim periods within those years. Although the disclosure requirements may be expanded where certain assets or liabilities are fair valued such as those related to stock compensation expense and hedging activities, the Company does not expect
the adoption of SFAS No. 157 to have a material impact on the Companys financial statements.

3. Cash Call Receivable

Cash call receivable represents the Companys proportionate share of planned authorized expenditures payable to the operator upon execution of the
final drilling authorization of expenditures and an advance payment to a drilling contractor. Of the total cash calls paid during the year ended December 31, 2006, $8.2 million was paid to Geostar Corporation (Geostar), a
significant shareholder at the time, and the remainder was paid to other outside parties. In 2005, Geostar refunded $2.1 million of unused cash call balances to the Company pursuant to the acquisition of Geostars working interests in East
Texas. The Company made advance payments totaling $2.0 million to a drilling contractor prior to the delivery of a drilling rig in November 2006. The advance payments will be amortized over the three-year term of the drilling contract agreement on a
straight line basis as a reduction to capitalized natural gas and oil property costs.

At December 31, 2006, unproved properties not being amortized consisted of drilling in
progress costs and acreage acquisition costs of $13.0 million and $76.6 million, respectively. As of December 31, 2005, unproved properties not being amortized consisted of drilling in progress costs and acreage acquisition costs of $439,000
and $73.6 million, respectively.

As of December 31, 2006, 2005 and 2004, the results of managements ceiling test evaluation
resulted in an impairment of the U.S. proved properties of $56.3 million, $8.7 million and $6.3 million, respectively. The December 31, 2006 U.S. proved property impairment was based on post end of year weighted average, after basis adjustment,
prices held constant of $6.11 per Mcf for natural gas and $54.85 per barrel of oil. Management determined that an impairment was not required on the Australian properties at December 31, 2006, 2005 or 2004.

For the years ended December 31, 2006, 2005 and 2004, expenditures on natural gas and oil properties totaled $67.4 million, $88.1 million and $34.2
million, respectively.

5. Geostar Acquisition

On June 17, 2005, the Company completed the acquisition of additional leasehold and working interests from Geostar in the deep Bossier Hilltop prospect of East Texas and in the Powder River Basin of Wyoming and
Montana (the Geostar Acquisition Properties). The Company paid a total of $73.1 million, after acquisition costs of $400,000 and purchase price adjustments of $4.2 million for the interest acquired from January 1, 2005
(Effective Date) to June 17, 2005 (Acquisition Date). This amount consisted of $30.9 million in cash, 1,650,133 common shares valued at $6.0 million based on a per share price of CDN$4.50 and $32.0 million in unsecured
subordinated notes scheduled to mature on January 31, 2006 and bearing interest at the rate of 3.42% (Geostar Subordinated Notes). The acquisition was accounted for using the purchase method in which the cost of the acquisition is
allocated first to identifiable net assets acquired based on estimated fair values. The results of operations are included in the accompanying consolidated financial statements only from the Acquisition Date. On March 31, 2006, the purchase
price adjustment of $4.2 million was settled for $2.1 million in cash and the issuance of 548,128 common shares of the Company valued at CDN$4.50 per share.

The initial carrying values of the Geostar Acquisition Properties as of June 17, 2005 was entirely allocated to natural gas and oil properties, of which $14.5 million was for proved developed properties, $8.7
million was for proved undeveloped properties and $49.9 million was for unproved properties.

In addition, Geostar may receive additional
common shares at prevailing market prices 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. For additional information, see Footnote 13, Related Party TransactionsGeostar Corporation.

On August 11, 2005, the Company executed an agreement with Geostar whereby the Geostar Subordinated Notes were cancelled. In conjunction with the
cancellation of the Geostar Subordinated Notes, the Company issued to Geostar 6,373,694 common shares of the Company valued at $17.0 million based on a per share price of CDN $3.25 and a new unsecured subordinated note (New Geostar
Subordinated Note) for $15.0 million. The New Geostar Subordinated Note was to bear interest, payable monthly commencing February 15, 2006, at three-month LIBOR plus 4.5%. On November 28, 2005, concurrent with the transaction with
Chesapeake Energy Corporation (Chesapeake), the New Geostar Subordinated Note was paid in full, as required by the agreement.

The following unaudited pro forma results for the years ended December 31, 2005 and 2004 show
the effect on the Companys consolidated results of operations as if the Geostar Acquisition had occurred at the beginning of each respective period presented. The pro forma results are the result of combining the statement of operations of the
Company with the statements of revenues and direct operating expenses for the properties acquired from Geostar adjusted for (1) the financing and share issuance directly attributable to the acquisition, (2) assumption of ARO liabilities
and accretion expense for the properties acquired and (3) additional depreciation, depletion and amortization expense as a result of the Companys increased ownership in the acquired properties. The statements of revenues and direct
operating expenses for the Geostar assets exclude all other historical expenses of Geostar. As a result, certain estimates and judgments were made in preparing the pro forma adjustments. Further, the pro forma information includes numerous
assumptions and is not necessarily indicative of future results of operations.

Senior Secured Notes

On June 17, 2005, we issued $63.0 million in principal amount of senior secured notes. On September 19, 2005, we issued to the holders of these 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 our assets, bear interest at the sum of the three-month LIBOR rate plus 6% (11.48% at December 31, 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 our 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 our 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, we 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. The Company initially recorded a liability of $17.0
million related to common shares to be issued and a corresponding amount recorded as a debt discount to be accreted to interest expense using the effective interest method. The Company also incurred an estimated $3.0 million of direct financing
costs for legal fees and fees paid to an agent as deferred charges and will amortize these costs over the term of the Senior Secured Notes.

In conjunction with the senior secured notes, we issued to the note holders pursuant to subscription rights the following number of additional common shares, based on the five-day weighted average trading price immediately prior to the date
of issuance as follows

As of December 31, 2006 and 2005, the Company had obligations to issue additional common
shares valued at $606,000 and $11.2 million, respectively, under the senior secured notes.

We have 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, we will issue to note holders subscription
receipts entitling them 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. Under the terms of the Senior Secured Notes, the Company may not at any time issue common shares to note holders to the extent the issuance of the common shares would cause the note holders and/or their affiliates to beneficially own more
than 9.9% of our outstanding common shares. In addition, the aggregate common shares issueable to the holders of the Senior Secured Notes are limited to the maximum number that may be issued without breaching the Companys obligations under the
rules and regulations of the principal market or exchange where the Companys common shares trade. In the event the issuance of common shares to the holders of the Senior Secured Note reach that maximum, the issuances would be proportionately
reduced, and the Company would be required to pay cash for such unissued common shares on a formula for determining the number of common shares required to be issued. In the event of a change of control or upon a sale of substantially all of the
Companys assets or a reorganization or merger where the Company is not the surviving entity, the holders of the Senior Secured Notes may require the Company to accelerate the future issuance of common shares.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



The issuance of additional senior secured notes is contingent upon compliance with reserves to net
senior secured notes debt coverage ratios and other general covenants and conditions. Under the senior secured notes, the PV(10) valuation 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. From the first anniversary of the issuance of the senior secured notes up to the second anniversary of the
issuance of the notes, proved reserves PV(10) (1P (PV10)) to net senior secured notes debt must be a minimum of 1.0:1. On the second anniversary date of the senior secured notes, the 1P PV(10) reserve ratio covenant increases to a
minimum of 1.5:1 and it increases to 2.0:1 on the third anniversary date and for all test periods thereafter until maturity. 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 first anniversary date and 2.0:1 to issue additional notes. On the first anniversary date of the senior secured
notes, the 2P PV(10) reserve ratio maintenance covenant and covenant to issue additional notes increased to a minimum of 2.5:1, 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. 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. As of December 31, 2006, the Company
was in compliance with all debt covenants. 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.

Our bank deposit accounts are subject to account agreements in favor of our senior lenders that allow the senior lenders to take certain
actions under specific circumstances to pay interest and/or principal outstanding related to the senior secured notes.

Convertible Senior Debentures

In November 2004, the Company issued $30.0 million aggregate principal amount of convertible senior unsecured debentures
(Convertible Senior Debentures). The Convertible Senior Debentures have a term of five years and will be due November 20, 2009 and 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 6,849,315 common shares at a conversion price of $4.38 per share. The Convertible Senior Debentures may be redeemed at any time after November 12, 2006 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.

The Company incurred an estimated $1.9 million of direct financing costs for legal fees and other expenses as deferred charges, which are
being amortized over the term of Convertible Senior Debentures. The Company also issued 259,740 broker warrants with an exercise price of $3.87 and a fair value of $359,000. Interest expense relating to the amortization of the warrants for each of
the years ended December 31, 2006, 2005 and 2004 was $72,000, $72,000 and $6,000, respectively. There was no beneficial conversion feature associated with the Convertible Senior Debentures.

On February 3, 2006, the Company issued 21,948 common shares upon exercise of 21,948 broker warrants at $3.87 per share issued in connection with
the sale of the Convertible Senior Debentures. The remaining 237,792 broker warrants expired in May 2006.

Subordinated Unsecured Notes Payable

The Companys subordinated unsecured notes mature between April 2009 and September 2009, bear interest at 10% per annum
and are callable by the Company after two years at 108% of the principal amount. The

call premium reduces to 105% after three years and 101% after four years. The subscribers were issued 232,521 warrants exercisable at prices ranging from
$2.76 to $3.03 expiring at varying dates between April 2009 and September 2009. A value of $235,000 was ascribed to the warrants and recorded as a debt discount to be accreted to interest expense using the effective interest method. Cash commissions
of $196,000 were incurred, which have been capitalized and are being amortized over the term of the subordinated unsecured notes.

7. Drilling Advances Liability

On September 23, 2002, the Company pre-sold working interests to third parties in four wells for $4.0 million to be used for the planned drilling
program on the Companys East Texas Bossier field. The amount was classified as a drilling advances liability, with 25% being credited to natural gas and oil properties when a well was drilled. One well was drilled in 2003, two in
2004 and one well in 2005. A total of 2,005,027 common share purchase warrants (the Bossier Warrants) were issued to subscribers on a pro-rata basis and were fully vested and non-forfeitable at the date of issuance. The Bossier Warrants
had a three year term, expiring on September 23, 2005, entitling the holder to acquire one common share of Company at a cash price of $1.49 per share or on a cashless exercise basis. Under the cashless exercise basis, the holder does not pay
cash consideration at the time the warrants are exercised but agrees to surrender the required number of shares (based on the trading price as of the exercise date) to settle the amounts due on the exercise. In September 2005, the 2,005,027 Bossier
Warrants were exercised and converted into common shares of the Company. Of the warrants exercised, 207,814 were exercised for cash proceeds of $413,000 and 1,797,213 were exercised on a cashless basis. The Bossier Warrants exercised on a cashless
basis resulted in the issuance of 841,224 net Company common shares.

The Company determined the fair value of the share purchase warrants
relating to the private placement offering for drilling advances liability using the Black-Scholes-Merton option pricing model, using weighted average assumption of a nil dividend yield, expected volatility of 30%, a risk-free interest rate of 5%
and a term of one year, after the hold period. As such, in 2002, the Company recorded a deferred charge of $425,000 as additional paid-in capital, which was amortized once drilling commenced and on the same basis as the release of the drilling
advances liability.

9. Equity Compensation Plans

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

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

On June 1, 2006, our
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 December 31, 2006,
no stock options had been granted under the 2006 Gastar Long-Term Stock Incentive Plan.

In applying the provisions of SFAS
No. 123(R), the Company used the following assumptions:

Valuation and Amortization Method.    The Company
estimates the fair value of share-based awards granted using the Black-Scholes-Merton valuation model. The proportionate fair value of all awards is amortized on a straight-line basis over its requisite service periods, which generally is the
individual vesting period for each grant.

Expected Life.    The expected life of awards granted represents the
period of time that stock options are expected to be outstanding. The Company determined 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. In 2006, the Company utilized a forfeitures rate of 5%
in determining initial compensation expense. Prior to 2006, the Company did not include expected forfeitures in determining initial compensation expense.

The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes-Merton valuation pricing model. During the years ended December 31, 2006, 2005 and 2004, we granted 4,790,000,
711,000 and 5,470,000 stock options, respectively. A summary of the weighted average assumptions and results for stock options granted during the years ended December 31, 2006, 2005 and 2004 are as follows:



|                         |  |                                 |   |  |      |   |  |      |

Stock-Based Compensation

For the years ended December 31, 2006, 2005 and 2004, the Company recorded $3.9 million, $2.3 million and $1.4 million, respectively, consisting of
stock-based compensation expense for stock options granted using the fair-value method. All stock based compensation costs were expensed and not tax effected as the Company currently records no income tax expense. All common shares issued upon
exercise are reserved and non-assessable.

At December 31, 2006, the Company had unvested stock options to purchase 7,541,250 common
shares with a weighted average grant date fair value of $1.26. As of December 31, 2006, the Company had approximately $4.8 million of total unrecognized compensation cost related to unvested stock options, which is expected to be amortized over
the following periods:

13. Related Party Transactions

Chesapeake Energy Corporation

On November 4, 2005, the Company completed an integrated
transaction with Chesapeake whereby Chesapeake acquired 27,151,641 million newly issued Company common shares equal to 19.9% of the then outstanding common shares, acquired a 33.3% working interest in the Companys Bossier play in the
Hilltop area of East Texas and formed an area of mutual interest to explore jointly in 13 counties in East Texas. As part of this transaction, Chesapeake paid an additional $7.8 million, before fees and expenses, to reimburse the Company for
Chesapeakes pro rata share of leasehold interests acquired and to pay a disproportionate amount of future drilling costs in exchange for an undivided 33.3% of the Companys leasehold working interests in the deep Bossier Hilltop prospect,
less and except 160 acres surrounding each existing well bore. Chesapeake agreed to pay 44.44% of the drilling costs through casing point in the first six wells drilled by the parties in the Hilltop prospect to a depth sufficient to test the deep
Bossier formation (an approximate depth of 19,000 feet) in order to earn its 33.33% leasehold working interest. The leasehold reimbursement was recorded as a reduction to natural gas and oil property cost. The Company utilized a portion of the
proceeds of the Chesapeake transaction to pay the New Geostar Subordinated Note in full.

As a result of its purchase of common shares,
Chesapeake has the right to negotiate exclusively with the Company for a period of 30 days on any proposed sale of assets. Additionally, Chesapeake has the right, with certain exceptions, to maintain its percentage ownership of the Company, on a
fully diluted basis, by participating in future stock issuances and has the right to an observer being present at meetings of the Board of Directors.

On November 11, 2006, Chesapeake acquired an additional 5,000,000 common shares in a private placement transaction to institutional investors. As of December 31, 2006, Chesapeake owned 32,191,641 common
shares, or 16.5% of the Companys outstanding common shares.

All related party balances are the result of well operations activity
governed by an existing standard form joint operating agreement. All balances are typically due and payable within 30 days.

Geostar Corporation

As of December 31, 2006, Geostars was the beneficial owner of approximately 8.1% of the Companys common shares,
based on SEC filings. Our former Chairman of the Board who resigned August 1, 2006 is President and a major shareholder of Geostar. In 2001, the Company entered into a Participation and Operating Agreement (the POA) with Geostar.
The POA governed the joint activities of Geostar and Company in relation to United States and Australian property acquisition and exploration and development operations. In 2005, the POA was cancelled as it related to properties located in Texas and
Wyoming as a result of the Geostar Acquisition. Although the POA expired by its terms on June 15, 2006, the joint interest billing activity between the parties has continued with respect to interests in Victoria Australia and West Virginia
pursuant to the POA.

Various disputes have arisen primarily over the past year, in connection with the POA and general operating and
administrative activity between Geostar and the Company, including claims by Geostar that the Company owes Geostar approximately $3.0 million comprised of additional charges for operating and administrative costs not previously billed and
approximately $11.0 million in demands for finder fees for funds previously provided by Geostar on behalf of the Company, including the funds borrowed and repaid by the Company under a non-interest bearing convertible debenture agreement. The
Company strongly contends these additional Geostar charges are without merit, as no agreement exists that would obligate the Company to pay these amounts. Excluding the Geostar amounts deemed without merit, Geostar owes the Company approximately
$3.8 million at December 31, 2006.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



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. Based on Gastars look-back analysis at June 30, 2006, no additional shares are due to Geostar at this time. Gastar is still awaiting confirmation of Geostars
June 30, 2006 look-back review results.

As of the date of this filing, Geostar has neither responded to the June 30, 2006
look-back analysis provided by Gastar or provided an independent reserve analysis disputing Gastars June 30, 2006 look-back analysis, which, as called for in the Purchase and Sale Agreement, would be averaged with Gastars
independent reserve analysis for the purpose of determining how many, if any, shares would be due to Geostar.

15. Loss per share

In accordance with the provisions of SFAS No. 128, 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.

Litigation

The Company is party to various litigation matters arising out of the normal course of business. During 2006, the Company incurred $2.4 million of litigation settlement expense primarily related to a settlement
payment regarding Western Gas Resources, Inc., et. al., of a lawsuit involving a gas gathering agreement and its applicability to properties the Company exchanged in 2002. The ultimate outcome of the matters discussed below cannot presently
be determined, nor can the liability that could potentially result from an adverse outcome be reasonably estimated at this time. The Company does not expect that the outcome of these proceedings will have a material adverse effect on its financial
position, results of operations or cash flow. 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. 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.

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 and sold to Chesapeake Energy Corporation pursuant to a transaction closed November 4, 2005. The preferential right claimed is under an operating agreement is 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 and other related lawsuits 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. At December 31, 2006 the Companys present value,
discounted at 10%, of the leases in dispute was approximately $742,000. The case is currently being arbitrated. If settlement can not be reached, the Company intends to vigorously defend itself against this 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, Gastar sent a letter to Geostar demanding

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



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 also requested that Geostars Australian subsidiary provide a
record title assignment of Gastars beneficial interests in EL 4416, the exploration license in the Gippsland Basin property in Victoria, Australia. Gastar has requested an expedited hearing and is waiting for the scheduling of the hearing. The
Companys former Chairman of the Board is President and a major shareholder of Geostar.

Larry McNiell v. Geostar Corporation,
First Source Wyoming, Inc. and Gastar Exploration Ltd. (Case No. 2:06cv00911 TS); In the United States District Court for the District of Utah, Central Division.This lawsuit was filed by Larry McNeill seeking damages
arising out of certain agreements entered into with First Source Wyoming, Inc. (FSW), a Geostar subsidiary, and Geostar. In the lawsuit, McNeill asserts breaches of contract and conversion against GeoStar and FSW for their alleged
failures to make required payments, deliver required Gastar shares without restrictions and cover certain McNeills loans. McNeill asserts a cause of action for declaratory judgment against Gastar asking the Court to declare that Gastar cannot
place restrictions on the shares owed by GeoStar to McNeill. The Company filed a Motion to Dismiss for lack of personal jurisdiction in Utah and for McNeills failure to state a claim upon which relief can be granted. The Company will continue
to vigorously defend itself against this claim.

Roland Spongberg v. Geostar Corporation, First Source Wyoming, Inc. and Gastar
Exploration Ltd., and Does 1 through 100 (Case No. VC046736); In the Superior Court of California, Los Angeles County.This lawsuit was filed June 1, 2006 and arises out of Plaintiffs investment in First Source
Wyoming, Inc.s, a Geostar subsidiary, (FSW) Coalbed Methane Drilling Program. On December 28, 2001, Plaintiff entered a 2001 Coalbed Methane Subscription Agreement with FSW investing cash in exchange for a working interest in
wells in the Powder River Basin in Wyoming. Plaintiff alleges that FSW was used by Geostar and the Company to offer investment securities to the general public in the form of oil, gas and coalbed methane working interests. Plaintiff alleges he
entered into such agreement based on representations made at a meeting with certain Geostar and Company officers contemporaneously therewith, Plaintiff entered into a Conversion Agreement with Geostar by which Plaintiff had the right to exchange his
working interests for common shares of the Company held by Geostar. Plaintiff alleges he notified Geostar of his desire to convert his interest at a time when the Gastar stock was priced at $1.10 per share. Plaintiff alleges further that in
September 2004, Geostar informed him that he did not properly exercise his conversion rights, and therefore did not have claim to any Geostar Company shares. Plaintiff alleges that between the date of his election and September 2004, the
Companys stock price tripled. Plaintiff asserts claims against all defendants for fraud, negligent misrepresentation, breach of contract, breach of fiduciary duty, violations of Securities Exchange Act §10B, and conspiracy to defraud, and
seeks an accounting of the value of the Companys stock, compensatory, special and punitive damages, interest and attorneys fees. The Company plans to file a Motion to Dismiss for lack of personal jurisdiction in California and for
Plaintiffs failure to state a claim upon which relief can be granted to the Company. This claim is primarily related to Geostar actions and Company common shares claimed to be owed to the Plaintiff by Geostar. The Company intends to vigorously
defend itself against this claim.

Spencer D. Plummer, III v. ClassicStar Farm, Inc., GeoStar Corporation and Gastar Exploration,
Ltd. This arbitration was filed with the American Arbitration Association by Plaintiff on November 1, 2006 pursuant to Plaintiffs employment agreement with ClassicStar Farm, Inc., a Geostar subsidiary (ClassicStar).
Plaintiff asserts breaches of his employment agreement and subsequent termination agreement with ClassicStar claiming he was denied certain benefits pursuant to such agreements, including 699,249 common shares of the Company. The Company is not a
party to the employment agreement or termination agreement on which Plaintiffs claims

are expressly based; however, the Company and Plaintiff are parties to a previously cancelled stock option agreement for 400,000 stock options. The Company
has filed an answer asserting that it is not bound by the arbitration provision, and therefore, it should be dismissed from the arbitration. The Company also denies any liability to Plaintiff under the stock option agreement. An arbitrator has been
appointed and a ruling on the Companys motion for dismissal is anticipated by March 21, 2007. The Company intends to vigorously defend itself against this claim.

Commitments

During 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 advance payments totaling $2.0 million prior to drilling rig delivery in November 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 three-term
of the agreement.

In February 2007, the Company entered into a letter agreement with ETC Texas Pipeline, Ltd. that expands our existing
transportation and treating agreement to meet the future gathering, treating and transportation of natural gas produced and owned or controlled by the Company in the Hilltop area of East Texas. Under the letter agreement, ETC would construct a
gathering system sufficient to gather and treat up to 150 MMcfd, and the Company would deliver to ETC a minimum of approximately 135 Bcf over a 10-year period. Minimum annual sales over the 10-year period and fees for the gathering and treating of
natural gas are currently being negotiated.

Common Share Registration Obligation and Penalties

On November 17, 2006 (Closing Date), the Company issued to various subscribers 25 million of its common shares for $50.0 million
(Aggregate Subscription Price). The Company has agreed to use its reasonable commercial efforts to file a registration statement covering the resale of the common shares within 120 days of the Closing Date (the Filing
Deadline) and to cause the registration statement to be declared effective within 180 days of the Closing Date (the Effectiveness Deadline). The Company agreed to cause the registration statement to remain effective until the
earlier of (i) 30 days after all the common shares have been sold under the registration statement, or (ii) one year from the Closing Date (the Effectiveness Period). If the registration statement is not filed by the Filing
Deadline, the Company agreed to pay to the subscribers an amount in cash equal to 1.5% of the Aggregate Subscription Price per month for the period between the Filing Deadline and the date that the registration statement is filed. If the
registration statement is not declared effective by the Effectiveness Deadline or shall cease to be effective for any period of time during the Effectiveness Period, the Company agreed to pay to the subscriber an amount in cash equal to 1.5% of the
Aggregate Subscription Price per month until such time as the registration statement is declared effective or the common shares become freely tradable pursuant to Rule 144(k), generally two years. Such amounts will accrue daily and be paid monthly
in arrears. The total penalty fee payable to the subscribers is limited to aggregate payments of 8% of the Aggregate Subscription Price or $4.0 million. The Company filed an S-3 Registration Statement on February 2, 2007 in regards to the
common shares and is waiting for such to be declared effective once the Companys Annual Report on Form 10-K is filed.

Restoration, Removal and
Environmental Liabilities

The Company is subject to various regulatory and statutory requirements relating to the protection of the
environment. These requirements, in addition to contractual agreements and management decisions, result in the accrual of estimated future removal and site restoration costs. These costs are initially measured at a fair value and are recognized in
the consolidated financial statements as the resent value of expected future cash flows.

GASTAR EXPLORATION LTD. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



Subsequent to the initial measurement, the effect of the passage of time on the liability for the asset retirement obligation (accretion expense) and the
amortization of the asset retirement obligation cost are recognized in the results of operations. Costs attributable to these commitments and contingencies are expected to be incurred over an extended period of time and are to be funded mainly from
the Companys cash provided by operating activities. Although the ultimate impact of these matters on net earnings cannot be determined at this time, it could be material for any quarter or year.

Indemnifications

Indemnifications in the
ordinary course of business have been provided pursuant to provisions of purchase and sale contracts, service agreements, joint venture agreements, operating agreements and leasing agreements. In these agreements, the Company may indemnify
counterparties if certain events occur. These indemnification provisions vary on an agreement by agreement basis. In some cases, there are no pre-determined amounts or limits included in the indemnification provisions and the occurrence of
contingent events that will trigger payment, if any, is difficult to predict.

Employment Agreements

Under the terms of employment agreements executed in March 2005 and April 2005, the Company has agreed to indemnify two executives, who have acted at the
Companys request to be officers of the Company, to the extent permitted by law, against any and all damages, liabilities, costs, charges or expenses suffered by or incurred by the individuals as a result of their service. The nature of the
indemnification agreements prevents the Company from making a reasonable estimate of the maximum potential amount it could be required to pay to beneficiary of such indemnification agreement. In addition to defining the terms of employment, the
agreements provide for severance benefits of up to two years compensation.

17. Concentration of Risk and Significant Customers

Approximately 66% of the Companys 2006 revenues was from production from the Companys eight producing wells in the East Texas Bossier Field in
Texas.

During 2006, ETC Texas Pipeline Ltd. and Enserco Energy, Inc. accounted for 63% and 25% of the Companys natural gas and oil
revenues, respectively. During 2005, ETC. and Enserco accounted for 65% and 26%, respectively, of the Companys natural gas and oil revenues. During 2004, ETC and Western Gas Resources, Inc. accounted for 59% and 35%, respectively, of the
Companys natural gas and oil revenues. Although ETC is the major natural gas purchaser and transporter in the area of Gastars deep Bossier play and limited natural gas purchaser and transporter alternatives are currently available in
this area, management believes that other natural gas purchasers and transporters could ultimately be located thus minimizing a long-term material adverse impact on the Companys financial condition or results of operations. Management believes
that the loss of Enserco in the Powder River Basin would not have a long-term material adverse impact on the financial position or results of operations of the Company, as there are numerous other purchasers operating in the Powder River Basin.

|(1) | In accordance with U.S. principles, the Company recognizes revenue and expenses on the income statement 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 oil and gas 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.

|(3) | In accordance with U.S. principles, expenditures on mineral resource properties are expensed. For Canadian principles, the Company capitalizes expenditures on mineral resource
properties.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(4) | In accordance with U.S. principles, a ceiling test is applied to ensure the unamortized capitalized costs in each cost center do not exceed the sum of the present value, discounted
at 10 percent, of the estimated unescalated 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 U.S. 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 U.S. 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 U.S. 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 U.S. 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

On March 19, 2006, the
eighteen-month anniversary of the September 19, 2005 $10.0 million Senior Secured Notes issuance, the Company issued to the note holders an additional 375,939 common shares valued at CDN$714,286. The issuance of the common shares was exempt
from registration pursuant to Section 3(a)(9) of the Securities Act of 1933

In March 2007, the Company and its Australian joint
venture partner in PEL 238 agreed to acquire outstanding overriding royalty interests from several outside parties including directors of the joint venture partner. The terms of the agreements call for the Company to acquire and terminate its 35%
share of a 4% overriding royalty interest in PEL 238 at a net cash price of $2.5 million payable April 3, 2007. In addition, the Company is to reimburse its joint venture partner in cash for its 35% share of other overriding royalty interests
acquired and terminated by the joint venture partner using the joint venture partners common stock as compensation. The Company expects its share of the costs associated with the acquisition and termination of overriding royalty interests
acquired to be approximately $2.9 million due on or before May 2, 2007 or within three days of notice from the joint venture partner if the shares are issued after May 2, 2007.

Net Proved and Proved Developed Reserve
Summary

The Companys proved developed and proved undeveloped reserves are located only in the United States. The Company
cautions that there are many uncertainties inherent in estimating proved reserve quantities and in projecting future production rates and the timing of development expenditures. In addition, estimates of new discoveries are more imprecise than those
of properties with a production history. Accordingly, these estimates are expected to change as future information becomes available. Material revisions of reserve estimates may occur in the future; development and production of the oil and gas
reserves may not occur in the periods assumed and actual prices realized and actual costs incurred may vary significantly from those used. Proved reserves represent estimated quantities of natural gas, crude oil and condensate that geological and
engineering data demonstrate, with reasonable certainty, to be recoverable in future years from known reservoirs under economic and operating conditions existing at the time the estimates were made. Proved developed reserves are proved reserves
expected to be recovered through wells and equipment in place and under operating methods being utilized at the time the estimates were made.

The 2006 downward revision of previous estimates is primarily attributed to a decrease in natural
gas prices and performance revisions in our Powder River Basin reserves in Wyoming. A decline in natural gas prices of approximately 36% from 2005 resulted in a decrease in proved reserves of approximately 4,836 MMcf. The remaining proved reserve
revision of previous estimates is attributed to downward revisions in the Powder River Basin based on updated well performance and reservoir pressure data, which was partially offset by upward performance revisions in the East Texas Bossier field.

Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil and Gas Reserves

The following information has been developed utilizing procedures prescribed by SFAS No. 69 and based on natural gas and crude
oil reserve and production volumes estimated by the independent petroleum reservoir engineers. This information may be useful for certain comparison purposes but should not be solely relied upon in evaluating the Company or its performance. Further,
information contained in the following table should not be considered as representative of realistic assessments of future cash flows, nor should the standardized measure of discounted future net cash flows be viewed as representative of the current
value of the Companys oil and gas assets.

The future cash flows presented below are based on sales prices, cost rates and statutory
income tax rates in existence at year end. It is expected that material revisions to some estimates of natural gas and crude oil reserves may occur in the future, development and production of the reserves may occur in periods other than those
assumed, and actual prices realized and costs incurred may vary significantly from those used. Income tax expense has been computed using expected future tax rates and giving effect to tax deductions and credits available, under current laws, and
which relate to oil and gas producing activities. Operating loss carryforwards to the extent estimated to be available in the future were also considered, thereby reducing expected tax expense.

Management does not rely upon the following information in making investment and operating decisions. Such decisions are based upon a wide range of
factors, including estimates of probable as well as proved reserves and varying price and cost assumptions considered more representative of a range of possible economic conditions that may be anticipated.

The Standardized Measure of Discounted Future Net Cash Flows relating to proved oil and gas reserves is presented below:
