PART I



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

Overview

We are a Houston, Texas-based independent natural gas and oil company engaged in the exploration,
development and production of natural gas and oil in the United States and Australia. Our domestic drilling activities are focused on exploiting our multi-year inventory of drilling locations in the deep Bossier sands and Knowles Limestone plays in
the Hilltop area of East Texas and continuing exploitation of our coal bed methane, or CBM, assets in the Powder River Basin of Wyoming and Montana. Our operations in Australia are focused on the development of over 7.0 million
gross (2.9 million net) acres of CBM rights in New South Wales and Victoria, Australia. We believe that our dual focus enables us to generate high initial production and long-lived producing wells with strong cash flow dynamics from our East Texas
activities, while also providing us with significant reserve upside through the development of our Australian resource plays. We are a Canadian corporation incorporated in Alberta in 1987. We are publicly traded on the American Stock Exchange under
the ticker symbol GST and on the Toronto Stock Exchange, or TSX, under the ticker symbol YGA.

Our Strategy

Continue Exploitation of Existing East Texas Assets.Our East Texas
portfolio includes 18 producing wells, which we anticipate will grow to 25 wells over the next 12 months. We have identified numerous Bossier and Knowles Limestone potential drilling opportunities on our current acreage position. These assets
represent opportunities with strong return characteristics supportive of significant near-term production and cash flow growth.

Actively Manage Our Domestic Drilling Program.We believe operating our core East Texas properties enables us to control the timing and cost of our drilling budget, as well as control operating costs and the
marketing of our production. We have assembled an experienced team of operating professionals with specialized skills necessary to plan and execute the drilling and completion of the deep, high-temperature and high-pressure wells targeting the deep
Bossier formation.

Exploit CBM Asset Base.Our asset positions in southeastern Australia represent
opportunities for significant reserve growth through our CBM drilling programs. Due to our pilot production success and the anticipated build up in the energy infrastructure in New South Wales, we anticipate continued participation with our
operating partners in further pilot production, core-hole and other exploratory CBM activities. Initial commercial production from the Petroleum Exploration License PEL No. 238, or PEL 238, is anticipated in late 2008.
We continue to evaluate our other CBM assets in the Powder River Basin in Wyoming and Montana for continued development drilling and re-completion activities that provide a source of stable production and cash flow.

Manage and Utilize Technological Expertise.We believe that 3-D seismic analysis, enhanced natural gas recovery processes,
horizontal drilling, and other advanced drilling technologies and production techniques are useful tools that improve drilling results and ultimately enhance production and returns. We believe that utilizing these technologies and production
techniques in exploring for, developing and exploiting natural gas and oil properties will help us reduce drilling risks, lower finding costs and provide for more efficient production of natural gas and oil from our properties.

Pursue Opportunistic Acquisitions.    We review opportunities to acquire
producing properties, leasehold acreage and drilling prospects that are located in our core operating areas. We are seeking to acquire properties that provide a strategic fit with our existing activities or that represent new strategic areas that
have a proved reserve base coupled with significant exploration or exploitation potential.

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

Hilltop Area, East Texas.    The majority of our activities 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. This exploration play has attracted some of the largest and most active operators in the U.S. Wells in this area target multiple potentially productive
natural gas formations and are typically characterized by high initial production, significant decline rates and long-lived reserves.

Our
first successful operated well was spudded in 2003 and placed on production in September 2004. As of December 31, 2007, we had successfully completed 14 out of 15 deep Bossier wells and four out of four Knowles Limestone wells. During 2007, we
drilled and successfully completed a total of five gross (3.0 net) Bossier wells and three gross (1.5 net) Knowles Limestone wells.

In May
2007, we sold a portion of our undeveloped natural gas and oil acreage in the Hilltop area of East Texas for approximately $66.5 million, net of transaction costs of approximately $1.2 million, resulting in a gain on sale of $38.5 million. We
currently have a total of approximately 35,400 gross (16,300 net) acres in the Bossier play. In July 2007, we completed the processing of a 3-D seismic survey purchased earlier in the year. This survey covered all of our retained undeveloped acreage
position and is being interpreted and used in the selection of our drilling locations. For 2008, we plan to drill up to three deep Bossier wells and four Knowles Limestone wells.

For the year ended December 31, 2007, net production from the Hilltop area averaged 13.0 MMcf per day. In January 2008, net production from the
Hilltop area averaged approximately 20.2 MMcf per day.

Coalbed MethanePowder River Basin, Wyoming and Montana

We own an approximate 40% average working interest in approximately 55,000 gross (21,900 net) acres in the Powder River Basin of Wyoming and Montana. The
Powder River Basin has been an important natural gas 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 the 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 27 (12.5 net) CBM wells. As of December 31, 2007, we had an interest in 283 gross (125.2 net) productive CBM wells producing in the Basin. For the year ended December 31, 2007, our average net
production from our CBM properties in the Powder River Basin was approximately 5.1 MMcf per day. We anticipate continuing our recompletion and drilling program in 2008. Our activity level will be influenced by regional natural gas prices, which
remained lower than its historic prices relative to Gulf Coast Henry Hub natural gas prices during late 2007. Regional prices in early 2008 have rebounded to, or above, historic price levels.

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

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

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

During 2007,
we and our joint venture partner were approached by potential buyers with an interest in potentially contracting for up to 1 Tcf of natural gas from PEL 238. In March 2007, we announced that we and our joint venture partner had executed a Memorandum
of Understanding (MOU) with Macquarie Generation, a New South Wales government-owned electricity generator, for the potential future supply of natural gas for its Bayswater power station. 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 long-term natural gas supply and purchase agreement with Macquarie Generation could include up to 500 Bcf to be delivered over a
15 to 20 year period commencing in late 2010, though there is no assurance that such an agreement will ultimately be reached or that such volumes will ultimately be produced from PEL 238. In addition, a potential gas supply and purchase agreement
with Macquarie Generation would serve to underpin the development of the approximately 300 kilometers of pipeline infrastructure necessary to transport gas from the PEL 238 concession to Bayswater. An additional 150 kilometers of pipeline
infrastructure would be required to access the natural gas markets of Sydney-Newcastle-Wollongong area.

In November 2007, we announced
that we and our joint venture partner had entered into a second MOU with Babcock & Brown (Babcock & Brown MOU) to supply gas from the PEL 238 and PEL 433 concessions for use in the generation of electricity. The
Babcock & Brown MOU envisions the supply of up to 30 Bcf per year of natural gas from the Gunnedah Gas Project to be delivered over multiple years for use in a gas fueled power station to be developed by Babcock & Brown in northern
New South Wales, Australia commencing in late 2010. Natural gas sales under the anticipated agreements could be expanded to meet requirements for power station developments at other locations, though there is no assurance that such an agreement will
ultimately be reached or that such volumes will ultimately be produced from the PEL 238 and PEL 433 concessions.

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

Petroleum Assessment Lease 2, or PAL 2, was issued by the New South Wales Department of Primary Industries on
October 30, 2007. PAL 2, in which Gastar holds a 35% interest, lies within PEL 238 and covers the existing Bohena Project Area of approximately 65,000 gross acres including the Bibblewindi and Bohena Production Pilots, with umbilical areas
connecting to the Wilga Park Power Station. The assessment lease, which

##### Index to Financial Statements

is intended for the area to be assessed for an eventual production lease, allows gas production from the two production pilots to ultimately be transported
by a dedicated gas gathering system to the power station for electricity production and sale. We and our joint venture partner are in the permitting phase for the construction of the gathering system and pipeline, which is anticipated to be
completed by late 2008.

During 2008, we, together with our joint venture partner intend to expand our pilot production drilling program on
the PEL 238 concession. Through a planned development program in PEL 238 consisting of additional production pilot projects and core hole drilling, we are aiming to convert a portion of the substantial gross resource potential into additional
certifiable proved and probable reserves as we move towards large-scale commercial production. We anticipate the certification of proved reserves and the growth of our probable reserves as necessary to support the development of infrastructure to
service growing natural gas demand in New South Wales. Contracts and capital commitments for the construction of such infrastructure as well as gas sales or use contracts on PEL 238, will be necessary before we can recognize proved reserves under
SEC guidelines.

The area on which PEL 238 is located is subject to a native title claim lodged in March 2007 by the Gomeroi Narrabri
People (NSD437/07). See Governmental Regulation-Australian Governmental Regulation-Native Title.

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

PEL 433 is located south of PEL 238 where Gastar and our joint venture partner, Eastern
Star Gas Limited, are developing the Gunnedah Basin Gas Project (Coal Seam Gas Joint Venture). Coal evaluation core-hole drilling completed during the 1970s and 1980s by the New South Wales government identified the distribution and thickness of the
coal measures within a portion of PEL 433. The Hoskissons Coal Seam is believed to be approximately 4 to 6 meters thick and widely distributed within the eastern part of PEL 433. There has been no previous coal seam gas exploration and evaluation
work in the area, and there is no information on gas content, gas composition or coal permeability.

In July 2007, we entered into a
Farm-In Agreement with Eastern Star Gas Limited under which we have earned a 35% working interest in the PEL 433 and adjoining PEL 434 properties. Under the terms of the Farm-In Agreement, we paid the costs of a two core-hole program and the related
costs of the evaluation of the coal reservoirs intersected by the core-holes.

The two corehole drilling program commenced during July 2007
and evaluated the coal seam gas potential of the Hoskissons Coal Seam within the Late Permian Black Jack Coal Measures. Additional coring may be undertaken on PEL 433 to provide additional data on coal depth, thickness, permeability, gas contents
and composition.

The area believed to be the most prospective for coal seam gas within PEL 433 underlies and is in close proximity to the
Central Ranges Natural Gas Pipeline that links Dubbo with Tamworth and joins with the larger Moomba-Sydney Gas Pipeline. This gas pipeline would enable gas sales within the region and potentially in Sydney and surrounding markets.

The area on which PEL 433 is located is subject to a native title claim lodged in June 2002 by the Tubba-Gah People (NSD6010/02). See Governmental
RegulationAustralian Governmental RegulationNative Title.

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

##### Index to Financial Statements

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. In late 2006, we pre-funded $6.5 million for a 10-well drilling program, which commenced drilling operations in late 2006. The
program included the establishment of two five-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.

Prior to the completion
of the 10-well program mentioned above, Gastar and the operator of EL 4416, a subsidiary of GeoStar Corporation (GeoStar), became involved in a number of disputes concerning Gastars right to an assignment of its interest in EL 4416
and other jointly-owned properties. As a result, the operator has not provided Gastar with information concerning the results of the 10-well drilling program nor an accounting for the use of the funds provided for the drilling of the 10 CBM wells.
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. We have sent a letter to
GeoStar demanding the arbitration of these issues. See Item 3, Legal ProceedingsArbitration and Litigation with GeoStar Corporation and Affiliates.

No native title claims have been lodged at this time in relation to the area on which EL 4416 is located. See Governmental RegulationAustralian Governmental RegulationNative Title.

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.

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 any natural gas infrastructure. The initial gas market for PEL 238 natural gas is anticipated to be an electricity
generation facility owned and operated by Eastern Star Gas Ltd. 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 in the permitting phase for the construction of the gathering system and pipeline, which is anticipated to be completed by late 2008.

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. Recent announcements of planned LNG facilities in southern Queensland are to be sourced from coalbed methane
projects, which could potentially lead to the possibility of a portion of future PEL 238 production being sold to LNG export facilities. In March 2007, we announced that we had executed, along with our joint venture partner, a 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 Macquarie Generations Bayswater power
station. In November 2007, we announced that we and our Joint venture partner had entered into a second MOU with Babcock & Brown (Babcock & Brown MOU) to supply gas from the PEL 238 and PEL 433 concessions for use in
the generation of electricity. The Babcock & Brown MOU envisions the supply of up to 38 Bcf per year of natural gas from the Gunnedah Gas Project over multiple years for use in a gas fueled power station to be developed by
Babcock & Brown in northern New South Wales, Australia commencing in late 2010. Natural gas sales under the anticipated agreements could be expanded to meet requirements for power station developments at other locations, though there is no
assurance that such an agreement will ultimately be reached or that such volumes will ultimately be produced from the PEL 238 and PEL 433 concessions. In addition, a potential gas supply and purchase agreement with Macquarie Generation would serve
to underpin the development of the approximately 300 kilometers of pipeline infrastructure necessary to transport gas from the PEL 238 concession to Bayswater. An additional 150 kilometers of pipeline infrastructure would be required to access the
natural gas markets of Sydney-Newcastle-Wollongong area.

The area on which PEL 433 is located is subject to a native title claim lodged in
June 2002 by the Tubba-Gah People (NSD6010/02). See Governmental Regulation  Australian Governmental Regulation-Native Title.

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 the Appalachian Basin in 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 March 2008, we entered into formal agreements with ETC Texas Pipeline, Ltd. (ETC) for the gathering, treating,
purchase and transportation of our natural gas production from the Hilltop area of East Texas. These agreements are effective September 1, 2007 and have a term of 10 years. ETC currently provides us 50 MMcfd of treating capacity and 120 MMcfd
of gathering capacity. We have the right to request ETC build, at their cost, up to 150 MMcfd of treating and gathering capacity during the term of the agreement, provided that our production equals 85% of the then existing treating and gathering
capacity for a 30 day period. We may at any time elect to have our treating and gathering capacity increased subject to cost indemnifications to ETC. Additional treating and gathering capacity requests must be in at least 25 MMcfd and 5 MMcfd
increments, respectively. In addition, we must furnish to ETC information that reasonably demonstrates that our projected production for the five years after expansion is sufficient to warrant the costs to create the expanded treating and gathering
capacity. The incremental volume increases in treating and gathering capacity shall be subject to marginal increases in treating fees. Pursuant to the agreements, we have access up to 150 MMcfd of firm transportation on ETCs system or the
pipelines of its affiliates or subsidiaries from the tailgate of the treating facility to Katy Hub. We have the option to sell and ETC has the obligation to buy, up to 150 MMcfd of our Hilltop production at delivery points upstream of ETCs
gathering and treating facilities. We do not have an obligation to deliver to ETC volumes in excess of 150 MMcfd, but should ETC elect to purchase such excess volumes, purchases will be subject to the treating and gathering expansion terms set forth
in the agreements.

During 2007, ETC and Enserco Energy, Inc. (Enserco) accounted for 78% and 20% of our natural
gas and oil revenues, respectively. During 2006, sales to ETC and Enserco 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. Although ETC is the major natural gas purchaser and transporter in the area of our deep Bossier play and only 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 and would minimize any 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, many of whom 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.

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 smaller and have a more limited operating history than most of
our competitors 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 providing
the manpower to operate them and provide related services.

Governmental Regulation

In addition to the environmental regulations discussed below, 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 prospect or acreage.

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 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, or 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. The 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 natural gas

and oil wells; the spacing of wells; and the plugging and abandonment of wells and removal of related production equipment. These regulations can limit the
amount 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, or acquisition of urban land will require review and approval under the
commonwealth foreign investment policy and regulations.

Native Title.In a landmark Australian High Court
decision in 1992, it was recognized that the native title to land of Indigenous Australians survived the acquisition of sovereignty by the British Crown. However native title to any particular area will only survive to the present if it has not been
extinguished subsequently. Native title may be extinguished by the action of government, such as the creation of an interest that is inconsistent with native title. In particular, the grant of the right to exclusive possession through freehold title
or a lease will wholly extinguish native title. Native title may also be extinguished if the connection between the land and the group of Aboriginal people claiming native title has been lost. The Native Title Act 1993 (Cth) 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 how dealings affecting native title can be conducted in the future. Native title claims by Aboriginal groups can
cover 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 or determinations. To validly affect native title, permits and licenses must be granted in compliance with the Native Title Act 1993 (Cth).

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 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 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 U.S. natural gas and oil exploration and production operations and similar
operations that we do not operate but in which we own a working interest 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



10

##### Index to Financial Statements

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 transported, 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. In the past, proposals have been made to amend RCRA to rescind this exemption.
Repeal or modification of the exception or similar exemptions in state law could increase the amount of hazardous waste we are required to manage and dispose of and could cause us to incur increased operating cost, which could have a significant
impact on us as well as 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 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 CAA 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.

Our CBM production operations involve the use of gas-fired compressors to produce or 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 that have
been 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 the 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. One bill recently approved by the U.S. Senate Environment and
Public Works Committee, known as the Lieberman-Warner Climate Security Act or S.2191, would require a 70% reduction in emissions of greenhouse gases from sources within the United States between 2012 and 2050. The Lieberman-Warner bill proposes a
cap and trade scheme of regulation of greenhouse gas emissions or a ban on emissions above a defined reducing annual cap. Covered parties will be authorized to emit greenhouse emissions through the acquisition and subsequent surrender of
emission allowances that may be traded or acquired on the open market. A vote on this bill by the full Senate is expected to occur before mid-year 2008. In addition, at least 17 states have already taken legal measures to reduce emissions of
greenhouse gases, primarily through the planned development of greenhouse gas emission inventories and/or regional greenhouse gas cap and trade programs. Most of these cap and trade programs require either major sources of emissions, such as
electric power plants, or major producers of fuels, such as refineries or gas processing plants, to acquire and surrender emission allowances. The number of allowances available for purchase is reduced each year until the overall greenhouse gas
emission reduction goal is achieved. Depending on the particular program, we could be required to purchase and surrender allowances, either for greenhouse gas emissions resulting from our operations or from combustion of fuels (such as natural gas
or oil) we produce. Although we would not be impacted to a greater degree than other similarly situated producers of natural gas and oil, a stringent greenhouse gas control program could have an adverse effect on our cost of doing business and could
reduce demand for the natural gas and oil we produce.

Also, as a result of the U.S. Supreme Courts decision on April 2, 2007 in
Massachusetts, et al. v. EPA, the EPA may be required to regulate carbon dioxide and other greenhouse gas emissions from mobile sources, such as cars and trucks even if Congress does not adopt new legislation specifically addressing emissions
of greenhouse gases. The EPA has indicated that it will issue a rulemaking notice to address carbon dioxide and other greenhouse gas emissions from vehicles and automobile fuels, although the date for issuance of this notice has not been finalized.
The Supreme Courts holding in Massachusetts that greenhouse gases including carbon dioxide fall under the federal Clean Air Acts definition of air pollutant may also result in future regulation of carbon dioxide and
other greenhouse gas emissions from stationary sources under certain Clean Air Act programs. New federal or state restrictions on emissions of carbon dioxide that may be imposed in areas of the United States in which we conduct business could also
adversely affect our cost of doing business and demand for the natural gas and oil we produce.

Finally, legislation continues to be
introduced in Congress and development of regulations continues in the Department of Homeland Security, or DHS, 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. The federal Department of Homeland Security Appropriations Act of 2007 required the DHS to issue regulations establishing risk-based performance
standards for the security of chemical and industrial facilities, including natural gas and oil facilities that are deemed to present high levels of security risk. The DHS issued an interim final rule, known as the Chemical Facility
Anti-Terrorism Standards Interim Final Rule, in April 2007 regarding risk-based performance standards to be attained pursuant to the Act and, on November 20, 2007, further issued an Appendix A to the interim rule that establish chemicals of
interest and their respective threshold quantities that trigger compliance with this rule. Facilities that possess the threshold quantities of chemicals of interest must submit to an initial screening process for DHS to determine if they present a
high level of security risk. Facilities that are deemed to pose a high level of security risk will be required to prepare and submit Security Vulnerability Assessments and Site Security Plans and comply with other regulatory requirements including
those regarding inspections, audits, recordkeeping and protection of Chemical-terrorism Vulnerability Information. We have not yet determined the extent to which our facilities are subject to the interim rules or the associated costs to comply, but
it is possible that such costs 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.

Australia ratified the Kyoto Protocol on December 3, 2007, and officially
committed to meeting its Kyoto Protocol target. Australia set a target to reduce greenhouse gas emissions by 60% on 2000 levels by 2050 and committed to actively participate in negotiations working towards a post 2012 agreement involving developed
and developing countries. Australia has introduced a National Greenhouse and Energy Reporting Act 2007, which establishes a single national system for reporting greenhouse gas emissions, abatement actions and energy consumption and production
by corporations from July 1, 2008. Data reported through the system will underpin the Australian Emissions Trading Scheme, or AETS, which is to be introduced by 2010. The consultation stage and detailed design of the AETS is to be finalized by
the end of 2008. The government has made it clear that it plans to introduce a cap and trade scheme in which total emissions are capped, permits allocated up to the cap and trading allowed to let the market find the cheapest way to meet
any necessary emission reductions. As the details of the AETS are not yet finalized, we are unable at this stage to assess the likely impact of the AETS on our operations in Australia.

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.

Industry Segment and Geographic Information

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

Employees

As of March 10, 2008, we had 23 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.

|-------- | ------------

Risk Factors Related to Our
Business

In addition to the other information set forth elsewhere in this Form 10-K, you should carefully consider the following
material risk factors associated with our business and our common shares when evaluating Gastar. An investment in Gastar is subject to risks inherent in our business. The trading price of our common shares will be affected by the performance of our
business relative to, among other things, competition, market conditions and general economic and industry conditions. The value of an investment in Gastar may decrease, resulting in a loss.

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, such as Venezuela;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | 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 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. As of December 31, 2007, approximately 72% of our production is priced based on the Katy Hub
(Katy) basis point, and the remainder is priced on the CIG basis point. Recently, natural gas prices on CIG have been extremely volatile, and spot sales of natural gas in the region traded at prices substantially below historic levels,
when compared to prices in other primary natural gas sales points in the country. This has been attributed primarily to limitations in available pipeline capacity for natural gas deliveries out of the Rocky Mountain area. In 2007, spot prices for
CIG Rocky Mountains on occasion dipped to less than $1.00 per MMBtu. While this volatility currently has been alleviated by completion of a major pipeline system in January 2008, this relief may be offset over time by the expected increase in supply
of natural gas available in the Rocky Mountains. At December 31, 2007, the Katy hub basis traded at approximately par to Henry Hub, and CIG hub basis traded at approximately 11% less then Henry Hub. Low natural gas prices in any or all of the
areas where we operate would negatively impact our financial condition and results of operations.

In Victoria and New South Wales the wholesale price for gas is determined by contract negotiations and is
not related to a hub or spot market price. Prospective natural gas sales related to our pilot CBM project in New South Wales will be dependent on electricity prices in the area since the natural gas is being dedicated
initially as fuel for an electric generation facility.

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 successful exploration and development activities and/or acquire properties containing proved reserves. 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, which could have a material adverse effect on our financial condition, future cash flows and the results of operations.

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 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 $30.5 million, $84.8 million and $25.7 million for the years ended December 31, 2007, 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.

We have a substantial amount of debt, which may adversely affect our cash flow and our ability to operate our
business, to remain in compliance with debt covenants and make payments on our debt.

As December 31, 2007, we have had total debt of $133.3 million of which $100.0 million consisted of the 123/4%
senior secured notes due 2012 (123/4% Senior Secured Notes), $30.0 million consisted of convertible senior
debentures due 2009 and $3.3 million consisted of subordinated unsecured notes due 2009. Our level of indebtedness affects our operations in several ways, including the following:



| |  |  | We may have difficulty borrowing money in the future for acquisitions, capital expenditures or to meet our operating expenses or other general corporate
obligations;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We will need to use a substantial portion of our cash flows to pay principal and interest on our debt, which will reduce the amount of money we have for operations,
working capital, capital expenditures, expansion, acquisitions or general corporate or other business activities;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We have substantial capital requirements, and we may be unable to obtain needed financing on satisfactory terms;
| | - |  | ----------------------------------------------------------------------------------------------------------------



| |  |  | We may be more vulnerable to economic downturns and adverse developments in our industry or the economy in general, especially declines in natural gas and oil
prices; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



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

We may incur substantially more debt, which may intensify the risks described above, including our ability to service our indebtedness.

We may to incur substantially more debt in the future. Although the indenture governing the 123/4% Senior Secured Notes and our Revolving Credit Facility contain restrictions on our incurrence of additional indebtedness, these
restrictions are subject to a number of qualifications and exceptions, and under certain circumstances, indebtedness incurred in compliance with these restrictions could be substantial.

Disputes have arisen between GeoStar and us in connection with the POA, general operating and administrative activity, and purchase price adjustments relating to
certain Texas properties.

Over the past six years, we entered into various transactions or agreements with GeoStar, one of our
former majority shareholders and an affiliate of our former Chairman of the Board. In 2001, we entered into a Participation and Operating Agreement (the POA) with GeoStar that governed certain property acquisition, exploration and
development activities of GeoStar and us. Various disputes have arisen, primarily over the past year, in connection with the POA and general operating and administrative activity between GeoStar and us. GeoStar claims that we have breached alleged
agreements to reimburse it for various payments and services allegedly performed by GeoStar and its personnel and paid on our behalf by GeoStar. GeoStar claims that the amounts of the payments and the value of the services exceed $17.0 million.
GeoStar alternatively alleges that if there was no contract covering those payments and services, it allegedly is entitled to reimbursement on equitable principles. We have also requested that GeoStars Australian subsidiary provide a record
title assignment of our 75% beneficial interests in EL 4416, the exploration license in the Gippsland Basin property in Victoria, Australia. GeoStar seeks a declaration that we do not own rights in EL 4416. Although we strongly contend that these
additional GeoStar charges are without merit and that GeoStar owes us approximately $3.7 million at December 31, 2007, we may not prevail. Payment to GeoStar of the amounts asserted would have a material adverse effect on our financial
condition, future cash flows and the result of operations.

In addition, a dispute has arisen regarding the Purchase and Sale Agreements (the PSAs)
between GeoStar and the Company relating to certain East Texas properties acquired by us in 2005. The PSAs contain a provision whereby a Look Back Payment is calculated based in part on changes in proved and probable reserves
attributable to certain of our East Texas leasehold interests over certain periods of time. Payments to GeoStar under the PSAs, if any, are to be effected through the issuance of our common shares. On November 7, 2007, GeoStar submitted a
reserve report to us that reports substantially greater reserve estimates than the estimates we have obtained. GeoStar has also asserted that the Look Back analysis should be based on changes in reserves attributable to the entirety, or 8/8ths, of
the leasehold interests with respect to the East Texas properties, rather than on changes in reserves attributable to GeoStars net revenue interest in those properties as of the effectiveness of the PSAs, as we believe. We vigorously dispute
that GeoStars reserves report complies with the requirements of the PSAs and vigorously dispute GeoStars contention as to the portion of reserves subject to the Look Back analysis. However, if GeoStar were to present both of these
current assertions in litigation and obtain an outcome adverse to the Company on both issues, we could be required to issue a number of shares to GeoStar sufficient to cause a change in control of the ownership of Gastar.

In 2007, the Company recorded a $1.4 million litigation settlement expense accrual related to a proposed settlement with GeoStar regarding the various
GeoStar arbitration and litigation matters. The settlement proposal was never finalized. Information about our legal proceedings is set forth in Note 16Commitments and ContingenciesLitigation to our consolidated financial statements,
which begin on Page F-1.

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 drilling an exploration well, the operator of the well will typically obtain a preliminary title review of the drillsite lease 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. 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 Note
16Commitments and ContingenciesLitigation to our consolidated financial statements, which begin on page F-1.

A dispute between third
parties affecting the ownership of undivided interests in certain East Texas oil and gas leases that we sold in 2005 may make it difficult for us, as operator of those leases, to obtain funds for some of our planned joint drilling operations until
the dispute is resolved.

In 2005, we sold Chesapeake Energy Corporation a one-third undivided interest in various oil and gas
leases, located in Leon and Robertson Counties, Texas together with shares of our common stock. Navasota Resources, L.P. filed a lawsuit against us and Chesapeake asserting a preferential right to purchase the undivided leasehold interest under an
operating agreement. While this issue was resolved by the trial court in favor of Chesapeake, an appeals court has recently reversed and rendered judgment favoring Navasotas right to acquire the undivided interest. Chesapeake and the
Company filed a motion for rehearing and, if unsuccessful, may consider an appeal to the Texas Supreme Court. While ownership of this undivided leasehold interest remains unresolved, Chesapeake and Navasota are disputing responsibility for paying
the proportionate share of joint capital and operating costs relating to this interest or approving authorizations for future joint drilling expenditures. Delays in determining ultimate ownership of this interest could lead to the Company
paying a disproportionate share of costs at its own risk or result in a delay in drilling of wells planned on this acreage in East Texas, which could have a material adverse effect on our financial condition, future cash flows and the results of
operations.

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 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;
| | - |  | -----------------------------------------



| |  |  | Actual prices received for natural gas in the future being different than those used in the estimate;
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | 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, 2007, approximately 60% 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, 2007 assumes that we will spend significant development capital
expenditures to develop these reserves, including an estimated $39.1 million and $9.5 million in 2008 and 2009, respectively. 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, future cash flows and the 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 entered into contracts for the
services of drilling rigs in North America and Australia, we may not be successful in doing so in the future. 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 have a material adverse effect on our financial condition, future cash flows and the results of operations.

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 effect on our financial condition, future cash flows and the 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, 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.

Native title, which is based on the traditional laws of Aboriginal groups, was recognized in Australia in 1992. Since 1994 there has been a process under the Native Title Act 1993 (Cth) through which indigenous
groups claiming to hold native title can have their title formally recognized. Because native title, by definition, has existed uninterrupted since white settlement of Australia, claims with a reasonable prospect of success are
registered and registered claimants have certain rights to participate in government land use decisions affecting land to which they may hold native title. Through the claims process, there are some areas in Australia where native title
is now formally recognized. However, in New South Wales and Victoria, where we have our Australian operations, most native title claims are yet to be resolved.

Native title can and has been extinguished across much of Australia and cannot be revived. Native title may be wholly extinguished in relation to particular areas of land by a grant of an inconsistent title, such as
freehold or a lease conferring exclusive possession. Where this has occurred it is possible to determine that native title has been extinguished irrespective of the formal resolution of a claim. Native title has no effect in relation to land use in
such areas. Native title is also extinguished where the traditional Aboriginal owners have lost their traditional links to the land. This can usually only be determined through the claim resolution process.

Native title can impact our Australian operations in two important ways:



| |  |  | Validity of interests: Where we are seeking to obtain an authority to prospect, develop resources or construct a pipeline over land subject to a registered native
title claim or determination, in respect of which prior extinguishment cannot be demonstrated, it is necessary to follow the processes contained in the Commonwealth native title the Native Title Act 1993 (Cth) to ensure validity of the
authority insofar as it affects native title.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Costs and delays associated with procedural rights of registered native title claimants/holders when seeking government authorities: Under the Native Title Act
1993 (Cth), registered native title claimants or holders (native title parties) have certain procedural rights in relation to the grant of authorities by the state government in respect of land to which they may or do hold native title. We may
be required to attempt to reach agreement with any native title parties as to the terms on which they will agree to the grant of the authority we seek. Such an agreement may include immediate payments, revenue sharing, or both. Payments are likely
to apply even before the claim is formally resolved. An agreement may also restrict the area where prospecting or development can occur in order to ensure that areas of cultural heritage significance are preserved. Reaching agreement with a native
title party can be costly and cause delay. Generally, the costs associated with the grant of pipeline licenses are less than those for production approvals. It is possible to request the National Native Title Tribunal to arbitrate a dispute
regarding the terms on which a prospecting or production authority can be granted, if there has been no resolution after six months. Other processes are available for resolution of disputes regarding pipeline licensing approvals according to state
laws.

There are registered native title claims in the Gunnedah Basin in New South Wales affecting PEL 238 and 433. EL
4416 in the Gippsland Basin in Victoria is not presently subject to a native title claim. However, a claim may be lodged which affects this property in the future.

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;

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 79% of our revenues for the year ended December 31, 2007 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 East Texas could unexpectedly be disrupted or curtailed due to reservoir or mechanical problems. Our natural gas produced
from this area contains levels of carbon dioxide and hydrogen sulfide that are above levels accepted by gas purchasers. This production must be treated by the purchaser. A majority of our East Texas production is processed by the purchaser. If the
purchasers facilities ceased to operate, were destroyed or otherwise needed replacement, it could require 60 to 90 days to replace or repair these facilities. A 60 to 90 day curtailment of our East Texas production could reduce current
revenues by an estimated $5.0 to $7.5 million, with a corresponding reduction in our cash flow.

The CBM which we produce in the Powder River Basin
may be drained by offsetting production wells.

Our drilling locations in the Powder River Basin are spaced primarily using 80-acre
spacing. Producing wells located on the 80-acre spacing units contiguous with our drilling locations may drain the acreage underlying our wells. If a substantial number of productive wells are drilled on spacing units adjacent to our properties,
they may decrease our revenue and could have an adverse impact on the economically recoverable reserves of our properties that are susceptible to such drainage.

Our Powder River Basin CBM wells typically have a shorter reserve life and lower rates of production than conventional natural gas wells, which may adversely affect our profitability during periods of low natural gas prices.

The shallow coals from which we produce CBM in the Powder River Basin typically have a two to six year reserve life and have lower total
reserves and produce at lower rates than most conventional natural gas wells. We depend on drilling a large number of wells each year to replace production and reserves in the Powder River Basin and to distribute operational expenses over a larger
number of wells. A decline in natural gas prices could make certain wells uneconomical because production rates are lower on an individual well basis and may be insufficient to cover operational costs.

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 transporters in the Hilltop area in East Texas. For the year ended December 31, 2007, ETC accounted for
substantially all of our revenues from this area. If ETC were to cease purchasing and transporting our natural gas and we were unable to contract with another transporter, it would have a material adverse effect on our financial condition, future
cash flows and the 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 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.

In recent years pipeline capacity for natural gas deliveries out of the Rocky Mountain area has been, at times,
significantly constrained resulting in an oversupply and creating substantial discounts on spot natural gas prices received for regional production. This has had a substantial impact on the prices received for natural gas production from Wyoming and
Montana, as compared to Gulf Coast natural gas prices. While a recently completed interstate pipeline currently has alleviated the problem by providing access to the Midwest interstate pipelines and markets, the relief may be offset over time by the
expected increase in supply of natural gas available in the Rocky Mountains.

Australian natural gas markets and transmission
infrastructure exists but they are not as developed or interconnected as the markets and infrastructure in the United States. Specifically, the PEL 238 concession is currently not served by natural gas transmission infrastructure. The initial gas
market for PEL 238 natural gas is anticipated to be an electricity generation facility located near the town of Narrabri, New South Wales. A short transmission pipeline is required to be built to serve this initial market. Access to a larger
electricity facility will require construction of a pipeline of approximately 300 kilometers to reach PEL 238 with an additional 150 kilometers of pipeline infrastructure required to access the natural gas markets in the Sydney-Newcastle-Wollongong
markets. The capital costs for these projects, if deemed feasible, would be substantial in order to realize the value of any identified reserves and construction would require significant amounts of time.

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. At the time production commences, the existing pipelines may have constraints in the capacity available to transport natural gas from the EL 4416 license to markets in the area of Sydney, Melbourne and Tasmania.

Our exploration rights in Australia are subject to renewal at the discretion of the government.

Coal bed methane exploration in Victoria is conducted under an exploration license granted under the Mineral Resources (Sustainable Development) Act
1990 (Victoria) which is granted at the discretion of the Minister for Primary Industries. Each exploration license requires the expenditure of a set amount of exploration costs and is generally subject to renewal for five years after the
initial term of five years. On renewal of an exploration license, the Minister may require reduction of the area to which the exploration license applies.

Coal bed methane exploration in New South Wales is conducted under a Petroleum Exploration License (PEL) granted under the Petroleum (Onshore) Act 1991 (NSW), which is granted at the discretion of
the Minister. Each PEL requires the expenditure of a set amount of exploration costs and is generally subject to renewal a term of up to six years after the initial term of up to six years. On renewal of a PEL, the Minister may require reduction of
the area to which the PEL applies.

We cannot assure that our exploration licenses or PELs will be renewed. Non-renewal or loss of an
exploration licenses or PELs could adversely affect our exploration and development plans, results of operations, financial condition or cash flows.

Competition in the natural gas and oil industry is intense. We are smaller and have less operating history than
many 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 have a material adverse effect on our financial condition,
future cash flows and the 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



26

##### Table of Contents

##### Index to Financial Statements

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, many 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. If one or more of the technologies that we currently use or may implement in the
future were to become obsolete or if we are unable to use the most advanced commercially available technology, it could have a material adverse effect on our financial condition, future cash flows and the results of operations.

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.

Our 2008 capital expenditures under our current
business plan are estimated to total approximately $65.4 million, of which $43.4 million is estimated to be spent on unconventional natural gas and oil exploration and development operations in East Texas, $7.4 million is estimated to be spent on
CBM projects and additional projects in the United States and $14.6 million is estimated to be spent on CBM projects in Australia. 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 and scheduled debt maturities beyond the next 12
months. 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 credit agreements will 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.

Disputes with
GeoStar may make it difficult for us to raise capital through the sale of equity.

The 2005 Purchase and Sale Agreements, or 2005
PSAs, between GeoStar and the Company relating to certain East Texas properties acquired by the Company contain a look back contingent payment provision that is the subject of claims in certain litigation matters with GeoStar. The
2005 PSAs sets forth a formula by which



27



---

##### Table of Contents

##### Index to Financial Statements

the amount of the look back payment is based in large part upon estimates of proved and probable reserves attributable to the East Texas properties as of
June 30 of 2006 and 2007. Under the 2005 PSAs, the look back payment is to be settled by the issuance of our common shares. GeoStar asserts that, under its calculations, it is entitled to a look back payment of approximately 1.7 billion shares
of our common stock, which if issued would constitute approximately 89% of our outstanding common equity. The Company strongly disputes GeoStars assertions. While these litigation matters remain pending, it will be difficult for us to
raise equity capital through the sale of our common stock to fund future operations and capital needs. Information about our legal proceedings with GeoStar is set forth under the caption LitigationArbitration and Litigation with GeoStar
and its Affiliates in Note 16Commitments and Contingencies to our consolidated financial statements, which begin on page F-1.

Hedging of
our production may result in losses or prevent us from benefiting to the fullest extent possible from increases in prices for natural gas and oil.

In September 2007, we commenced hedging our natural gas production utilizing costless collars. Although these hedges may partially protect us from by declines in natural gas prices, the use of these arrangements may
limit our ability to benefit from significant increases in the prices of natural gas.

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, chief financial officer and chief
operating officer could negatively impact our future operations. We have employment agreements 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 financial condition, future cash flows
and the results of operations.

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, 2007, Chesapeake Energy Corporation owned approximately 16.3% 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 of or amendment to provisions in our Amended and Restated
Articles of Incorporation, 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 an observer present 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 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 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.

A change of control of the Company could have a material adverse effect on us, and if GeoStar prevails in its look back claim, it could result in a
change of control of the Company.

Under the terms or agreements for our
123/4% Senior Secured Notes, the Revolving Credit Facility and the convertible senior debentures, which collectively constitute
substantially all of our indebtedness, upon the occurrence of specific types of changes of control in the Company, we will be required to either repay or make an offer to repurchase all outstanding debt under these agreements. If such a change
of control were to occur, including as a result of payment of a disputed look back payment if GeoStar were to prevail in its assertion discussed elsewhere in this report, we may not have sufficient funds available to repay debt becoming due or
repurchase debt tendered to us. In that event, we would need to seek waivers from lenders and debtholders, which may not be obtainable, or a refinancing, which may not be available or on terms as favorable as the refinanced debt. Such a required
repayment, repurchase or refinancing could have a material adverse effect on our financial condition, future cash flows and the results of operations.

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 are 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 large 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 material adverse effect on our financial condition, future cash flows and the results of 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 might trade. 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 not 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 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 123/4% Senior Secured Notes that were sold in a November 2007 private placement could result in us being required to pay additional interest, which could be significant.

On November 29, 2007, we sold $100.0 million of our 123/4% Senior Secured Notes. We are obligated to prepare and file with the SEC within 150 days of the issue date of the 123/4% Senior Secured Notes, or April 27, 2008, a registration statement to exchange the 123/4% Senior Secured Notes for registered, publicly tradable notes that have substantially identical terms as the 123/4% Senior Secured Notes. We are to use our best efforts to cause the registration statement to be declared effective within 240 day
of the issue date of the 123/4% Senior Secured Notes, or July 24, 2008. In the event we fail to meet our registration
obligations we will be required to pay additional cash interest on the 123/4% Senior Secured Notes equal to 0.25% per annum
for the first 90-day period, increasing an additional 0.25% the next 90-day period, to a maximum of 0.50% per annum.

Issuance of the common shares upon conversion of our convertible debenture 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 conversion of our convertible debentures. These issuances will dilute the ownership
interest of existing shareholders. Any sales in the public market of the common shares issuable upon conversion of additional common shares could adversely affect prevailing market prices of our common shares. In addition, the existence of these
convertible debentures may encourage short selling by market participants.

Natural Gas and Oil Reserves

Our estimated total net proved reserves of natural gas and oil as of
December 31, 2007 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 NSAI and are part of their reserve reports on our
natural gas and oil properties. The estimates of NSAI were based on a review of geologic, economic, ownership and engineering data that we provided.

In accordance with SEC regulations, estimates of our proved reserves and future net revenues are made using sales prices in effect as of the date of the 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 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 the NSAI reserve reports are the period-end prices for natural gas and oil at December 31, 2007. 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, 2007
|                                        |  | Gas ($/MMBtu)           |       | Oil ($/Bbl)
|Production:                             |  |                         |       |             |   |      
|Hilltop Area, East Texas                |  | $                       | 6.795 |             | $ | 92.50
|Powder River Basin, Wyoming and Montana |  | $                       | 6.040 |             | $ |     

The weighted average natural gas and oil prices after basis adjustments used in our reserve
valuation as of December 31, 2007 were $6.08 per Mcf and $93.88 per barrel.

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, 2007. 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.

For additional information
concerning our estimated proved reserves, the standardized measure of discounted future net cash flows of the proved reserves at December 31, 2007, 2006 and 2005 and the changes in quantities and standardized measure of such reserves for each
of the three years then ended, see Note 21Supplemental Oil & Gas DisclosuresUnaudited to our consolidated financial statements, which begin on page F-1.

our 123/4% Senior Secured Notes and revolving credit facility contain covenants that prohibit us from paying cash dividends as
long as such debt remains outstanding. Pursuant to the provisions of the Business Corporations Act(Alberta), we are prohibited from declaring or paying a dividend if there are reasonable grounds for believing that (1) we are, or would
after the payment be, unable to pay our liabilities as they become due or (2) the realizable value of our assets would thereby be less than the aggregate of our liabilities and stated capital of all classes.

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 begin 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 FASB No. 123R, 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 CBM. We are also 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 Montana and in the Gunnedah and Gippsland Basins of Australia.

Our major domestic asset is approximately 35,400 gross (16,300 net) acres in the Bossier play in the Hilltop area of East Texas. During the past three years, we spent approximately $196.6 million in acreage, seismic
and reserve acquisition and exploratory and development drilling on this acreage. While we have not attained positive net income from operations in the past three years, and there can be no assurance that operating income and net earnings will be
achieved in future periods, our recent efforts have resulted in significant growth in production over the past three-year period. As we continue the exploitation and development drilling in the Hilltop area, we expect to show further improvement in
our operations.

Our international activities are focused on CBM development in Australia on over 6.0 million gross (2.1 million net)
acres in New South Wales. We are in the early stages of development of this potentially significant asset, which could have a material and positive long-term impact on our financial results. Although we currently have no commercial production, we
and our joint venture partner have been approached by potential buyers with an interest in potentially contracting for future deliveries of natural gas from PEL 238 for use in the generation of electricity. In September 2007, NSAI certified a
quantity of proved and probable reserves under guidelines established by the Society of Petroleum Engineers (SPE), as a result of the success of one of our pilot production projects on PEL 238. These reserves, however, are not yet
established as proved reserves under SEC guidelines nor can we assure that other unevaluated acreage will contain similar reserves.

Our
financial results depend upon many factors which significantly affect our results of operations including the following:



| |  |  | The level and success of exploration and development activity;
| | - |  | --------------------------------------------------------------



| |  |  | The sales prices of natural gas and crude oil;
| | - |  | ----------------------------------------------



| |  |  | The level of total sales volumes of natural gas and crude oil; and
| | - |  | ------------------------------------------------------------------



| |  |  | The availability of and our ability to raise the capital necessary to meet our cash flow and liquidity needs.
| | - |  | -------------------------------------------------------------------------------------------------------------

We plan our activities and budget based on conservative sales price assumptions, given the inherent volatility of natural gas and oil prices that are
influenced by many factors beyond our control. We focus our efforts on increasing natural gas and oil reserves and production and strive to control costs at an appropriate level. Our future earnings and cash flows are dependent on our ability to
manage our overall cost structure to a level that allows for profitable production. Our future earnings will also be impacted by the changes in the fair market value of hedges we executed to mitigate the volatility in the changes of natural gas and
oil prices in future periods. These instruments meet the criteria to be accounted for as cash flow hedges, and until settlement, the changes in fair market value of our hedges will be included as a component of stockholders equity to the
extent effective in periods of rising prices, these transactions will mitigate future earnings and in periods of declining prices will increase future earnings in the respective period the positions are settled.

Like other natural gas and oil exploration and production companies, we face the fact of natural production declines. As initial reservoir pressures are
depleted, natural gas and oil production from a given well will decrease. Thus, a natural gas and oil exploration and production company depletes part of its asset base with each

unit of natural gas and oil it produces. We attempt to overcome this natural decline by adding reserves in excess of what we produce through successful
drilling or acquisition. Our future growth will depend on our ability to continue to add reserves in excess of our production. We will maintain our focus on adding reserves through drilling and acquisitions, while placing a clear priority on
lowering our cost of replacing reserves. Consistent with our stated strategies, we will emphasize maintaining a high-quality inventory of drilling locations, while also focusing on improving our capital and cost efficiency.

Critical Accounting Policies and Estimates

The preparation of financial statements in accordance with
accounting principles generally accepted in the United States of America (US GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses, contingent assets and
liabilities and the related disclosures in the accompanying 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 are uncertain at the time the estimate is 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 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.

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 at December 31, 2006 and at June 30, 2007. 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 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 after
basis adjustments used in the reserve valuations as of December 31, 2006 and June 30,2007 were $6.12 per Mcf and $5.72 per Mcf, respectively.

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. At December 31, 2007, we had a ceiling impairment cushion of $45.2 million. A 10% decrease in prices would have resulted in a decrease in the cushion of approximately $24.1 million. A 10% increase in prices used
would have resulted in an increase in the cushion approximately $20.7 million.

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

Effect if different assumptions
used.A 10% increase in reserves would have decreased our depletion expense for the year ended December 31, 2007 by approximately 2%, while a 10% decrease in reserves would have increased our depletion expense by
approximately 3%.

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, 2007, we had $46.5 million allocated to unproved United States property costs which was comprised primarily of unevaluated acreage costs. The unproven property costs



39

##### Index to Financial Statements

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 1% for the year ended December 31, 2007.

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 Statement of 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 asset retirement obligation, or 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 primarily 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 as an estimate based on field or industry practices. We expect to see our calculations impacted significantly if interest rates move from
their current levels, 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.

Capitalized Interest

We capitalize interest for two purposes:    (1) capitalized interest on funds borrowed for specific projects, such as our long-term development of our CBM assets in New South Wales and
Victoria, Australia and (2) capitalized interest on borrowed funds used to invest in unproven natural gas and oil properties not being

##### Index to Financial Statements

amortized. The methodology for capitalizing interest on general funds, consistent with SFAS No. 34, Capitalization of Interest Cost,
begins with a determination of the borrowings applicable to our qualifying assets. The basis of this approach is the assumption that the portion of the interest costs that are capitalized on expenditures during an assets acquisition period
could have been avoided if the expenditures had not been made. This methodology takes the view that if funds are not required for construction then they would have been used to pay off other debt. We use our best judgment in determining which
borrowings represent the cost of financing the acquisition of the assets. The primary debt instruments included in the rate calculation of interest incurred on the funds is our 123/4% Senior Secured Notes. The interest to be capitalized for any period is derived by multiplying this fixed rate of interest times the average qualifying assets during the period. To qualify for
interest capitalization, we must continue to make progress on the development of the assets.

Stock-Based Compensation

Nature of Critical Estimate Item.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
required 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.

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 2007
and 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).

The Company reports compensation expense for stock options and restricted common shares granted to officers, directors and employees using the fair value
method in accordance with SFAS 123R. Stock-based compensation costs are recorded over the requisite service period, which approximates the vesting period.

The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes-Merton valuation pricing model. The fair value of all awards is expensed using the graded-vesting method,
which recognizes compensation costs over the requisite service period for each separately vesting tranche of an award as though the award were, in substance, multiple awards.

Assumption/Approach Used.    The Black-Scholes-Mertron model requires various highly judgmental assumptions including
volatility, expected option life and forfeiture rate. If any of the assumptions used in the Black-Scholes-Mertron model change significantly, stock-based compensation expense may differ materially in the future from that recorded in the current
period. The table below summarizes the key assumptions for the stock options granted for the periods indicated:

|Expected life (in years) |  | 6.25                            |   |  | 6.5  |  
|Expected forfeitures     |  | 5.0                             | % |  | 5.0  | %

Effect if different assumptions used.A 10% increase or decrease in
the volatility rate would increase or decrease our stock based compensation for the year ended December 31, 2007 by approximately 6.4% and 6.6%, respectively. A 10% increase or decrease in expected life would increase or decrease our stock
based compensation expense for the year ended December 31, 2007 by approximately 4.6% and 4.9%, respectively. A 10% increase or decrease in forfeiture rate would have a corresponding impact on our stock based compensation expense for the year
ended December 31, 2007.

Year Ended December 31, 2007 compared to Year Ended December 31, 2006

Revenues.Substantially all of our revenues are derived from the production of natural gas in the United States. Revenues
were $34.6 million for the year ended December 31, 2007, up 29% from $26.8 million for the year ended December 31, 2006. The increase in revenues was the result of a 42% increase in natural gas production primarily in East Texas, which was
partially offset by an 8% decrease in natural gas prices.

Production taxes.    We reported production taxes of
$765,000 for the year ended December 31, 2007, down from $1.5 million for the year ended December 31, 2006. This decrease was the result of tight sand credit refunds on our Texas natural gas sales and lower Wyoming taxes due to gas price
declines.

Lease operating expenses.    We reported lease operating expenses of $6.3 million for the year ended
December 31, 2007, up from $5.5 million for the year ended December 31, 2006. This increase was due to an increased number of producing wells and increased production. Our lease operating expenses were $0.95 per Mcfe for the year ended
December 31, 2007, compared to $1.18 per Mcfe for the comparable period in 2006.

Transportation and
treating.    We reported transportation expenses of $1.6 million for the years ended December 31, 2007 and 2006. Transportation and treating expense was constant as it relates to our Powder River Basin CBM production,
which did not change significantly from 2006.

Depreciation, depletion and amortization.Depreciation,
depletion and amortization was $21.5 million for the year ended December 31, 2007, up from $16.3 million for the year ended December 31, 2006. The increase in DD&A expense was the result of a 40% increase in production, primarily
attributable to new East Texas wells drilled during 2007. The DD&A rate for the year ended December 31, 2007 was $3.22 per Mcfe, as compared to $3.44 for the comparable period in 2006.

Impairment of natural gas and oil properties.Impairment of U.S. natural gas and oil properties was $28.5 million for the
year ended December 31, 2007, compared to $56.3 million for the comparable period ended December 31, 2006. The 2007 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 weighted average after basis
adjustment prices in effect at June 30, 2007, the date of the impairment, held constant at $5.72 per Mcf for natural gas, discounted at 10%, and unproven properties at historical costs of $43.6 million. The 2006 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, discounted at 10%, and unproven property at historical cost of $81.5 million, as adjusted for related income taxes and other adjustments.

General and administrative.We reported general and administrative expenses of $16.9 million for the year ended December 31, 2007, up from $13.5 million for the year ended
December 31, 2006. This increase in general and administrative expenses was primarily due to an increase in allowance for doubtful accounts and professional service charges, including Sarbanes-Oxley compliance costs, partially offset by a
decline in contract personnel costs. The allowance for doubtful accounts was increased by $3.7 million to fully reserve the GeoStar receivable due to current litigation. Non-cash stock-based compensation expense pursuant to the SFAS 123R, which is
included in general and administrative expenses, was $3.9 million for both years ended December 31, 2007 and 2006.

Litigation
settlement expense.    The $1.4 million litigation settlement expense incurred in 2007 was primarily the result of an accrual of a settlement payment related to a proposed settlement with GeoStar on certain matters. The
settlement proposal was never finalized (Note 16Commitments and Contingencies LitigationArbitration and Litigation with GeoStar Corporation and Affiliates). 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. litigation involving a gas gathering agreement and its applicability to properties we exchanged in 2002 and settlement of the Burning Rock Energy LLC,
et. al. litigation by assigning our interest in certain disputed properties.

Interest expense.We
reported interest expense of $14.1 million for the year ended December 31, 2006, compared to $15.6 million for the year ended December 31, 2006. The decrease in interest expense was primarily the result of $1.9 million of capitalized
interest in 2007, resulting from capital activity expansion in Texas and Australia. Interest expense includes deferred cost and debt discount amortization of $4.2 million for 2007, a decrease of $100,000 from the comparable 2006 period. There was no
capitalized interest in 2006

Debt extinguishment
expense.    We reported debt extinguishment expense of $15.7 million for the year ended December 31, 2007. This resulted from the expensing of a prepayment penalty of $3.7 million and deferred financing and debt discount
costs of $12.0 million incurred related to $73.0 million of senior secured notes. The senior secured notes were repaid prior to maturity with the proceeds from the sale of $100.0 million of 123/4% Senior Secured Notes in November 2007. There was no debt extinguishment expense in 2006.

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.

Production taxes.    We reported production taxes of $1.5 million for the year ended December 31, 2006, up from $1.1
million for the year ended December 31, 2005. This increase was the result of increased production from new wells and a $350,000 tight sands gas tax refund in 2005.

Lease operating expenses.    We reported lease operating expenses of $5.5 million for the year ended December 31, 2006, up from $3.9 million for the year ended December 31, 2005.
This increase was due to an increase in the number of producing wells. Our lease operating expenses were $1.18 per Mcfe for the year ended December 31, 2006, compared to $1.01 per Mcfe for the comparable period in 2005.

Transportation and treating.    We reported transportation expenses of $1.6
million for the year ended December 31, 2006, down from $2.0 million for the year ended December 31, 2005. The decrease in expense was primarily the result of lower Powder River Basin transportation costs. This decrease was the result of a
decrease in per Mcf cost from $1.43 per Mcf in 2005 to $0.88 per Mcf in 2006.

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 a 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 U.S. 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 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, discounted at 10%, and 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 was 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, discounted at 10%, and unproven properties at
historical costs of $93.3 million, 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. Non-cash stock-based compensation expense
for 2006 pursuant to the SFAS 123R, which is included in general and administrative expenses, 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 and settlement of the Burning Rock Energy LLC, et. al. litigation by assigning our interest in certain disputed properties. There was no
litigation settlement expense in 2005.

Interest expense.We reported interest expense of $15.6 million for
the year ended December 31, 2006, compared to $13.9 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. Interest expense includes
deferred financing cost and debt discount amortization of $4.3 million for 2006, a decrease of $500,000 from 2005.

Debt extinguishment
expense.    In June 2005, in conjunction with the issuance of the senior secured notes, the Company retired certain senior notes, resulting in a debt extinguishment expense of $1.4 million, comprised of $662,000 of early
prepayment penalty and $694,000 of unamortized deferred financing costs.

Liquidity and Capital Resources

At December 31, 2007, we had cash and cash equivalents of $85.9 million.
For the year ended December 31, 2007, we reported cash flow from operations of $7.4 million. Capital expenditures on natural gas and oil properties totaled $74.2 million, excluding property divestments, during the period for the year ended
December 31, 2007.

On November 29, 2007, Gastar USA sold $100.0
million aggregate principal amount of 123/4% Senior Secured Notes at an issue price of 99.50%. Approximately $76.7 million of
the $92.5 million net proceeds from the offering was used to repay the $73.0 million of our outstanding senior secured notes, with the remaining net proceeds used for general corporate purposes. The 123/4% Senior Secured Notes mature on December 1, 2012. The 123/4% Senior Secured Notes contain certain covenants that among other things limit Gastar USAs and the guarantors ability to: (i) incur additional indebtedness; (ii) pay distributions on, or
repurchase or redeem equity interests; (iii) make certain investments; (iv) incur liens; (v) enter into certain transactions with affiliates; and (vi) sell assets or consolidate or merge into other companies. Notwithstanding the
above, we may incur other indebtedness, which would be subordinate to the 123/4% Senior Secured Notes, up to an aggregate $25.0
million of indebtedness under the Revolving Credit Facility or such additional amounts of 123/4% Senior Secured Notes; provided,
that Gastar USAs consolidated cash flow to fixed charges for the most recent four quarters giving the effect of the incurrence at the beginning of such four-quarter-period is at least 2.0 to 1.0.

On November 29, 2007, concurrent with the closing of the 123/4% Senior Secured Notes, Gastar USA entered into a Revolving Credit Facility, which provides for an initial first priority lien
borrowing base of $19.4 million. At December 31, 2007, there were no amounts outstanding under the Revolving Credit Facility.

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

We continually evaluate our capital needs and compare them to our capital resources. To execute our operational plans, 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, sales of assets and the issuance of additional debt or equity. We may also attempt to balance future capital expenditures through joint venture
development of certain properties with industry partners. We cannot be certain that future funds will be available to fully execute our current business plan.

Our 2008 capital expenditures under our current business plan are estimated to total approximately $65.4 million, of which $43.4 million is estimated to be spent on unconventional natural gas and oil exploration and
development operations in East Texas, $7.4 million is estimated to be spent on CBM projects and additional projects in the United States and $14.6 million is estimated to be spent on CBM projects in Australia. Based on our current budget, we have
sufficient capital, together with internally generated cash flow, to fund our exploration and development activities in East Texas and Australia for 2008 and a significant portion of 2009s projected capital needs in excess of the next 12
months.

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

In the third and fourth quarters of 2007, we entered into two costless collar transactions with
counterparties. The first transaction covers a notional volume of 2,000 MMBtu per day or approximately 0.8 Bcf of natural gas production for the year 2008 with a $5.50 per MMBtu floor and a $7.50 MMBtu ceiling price that represent hedge prices at
Inside FERC Colorado Interstate Gas Rocky Mountains (CIG). The second transaction covers a notional volume of 5,000 MMBtu per day or approximately 1.8 Bcf for the year 2008 with a $6.75 per MMBtu floor and a $8.00 MMBtu ceiling price
that represent hedge prices at East-Houston-KatyHouston Ship Channel (HSC). The volume hedged as of December 31, 2007 represents approximately 43% of 2008 projected production, as estimated by our third party reservoir
engineer at December 31, 2007.

In January 2008, we hedged an additional 5,000 MMBtu per day of our Texas production at HSC prices
between $7.00 per MMBtu and $8.88 per MMBtu for February 2008 through December 2008 and hedged 800 MMBtu per day of natural gas of our Powder River Basin production at CIG prices between $6.00 per MMBtu and $7.90 per MMBtu for February 2008 through
December 2008. Additionally in February 2008, we hedged 5,000 MMBtu per day of our Texas production at HSC prices between $8.00 per MMBtu and $9.30 per MMBtu for January 2009 through December 2009. All 2008 hedges were costless collars.

Covenants in our 123/4% Senior Secured Notes Indenture and our Revolving Credit Facility Agreement restrict us from hedging more than 75% of the projected production from proved developed producing reserves.

At December 31, 2007, we were in compliance with all debt covenants.

Off Balance Sheet Arrangements

As of December 31, 2007, 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, 2007:

We have employment agreements with our Chief Executive Officer, Chief Financial Officer and Chief
operating 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

During 2006, we 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 are being 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-year term of the
agreement commencing November 2006.

In March 2008, we entered into formal agreements with ETC Texas Pipeline, Ltd. (ETC) for
the gathering, treating, purchase and transportation of our natural gas production from Hilltop area of East Texas. These agreements are effective September 1, 2007 and have a term of 10 years. ETC currently provides us 50 MMcfd of treating
capacity and 120 MMcfd of gathering capacity. We have the right to request ETC build, at their cost, up to 150 MMcfd of treating and gathering capacity during the term of the agreement, provided that our production equals 85% of the then existing
treating and gathering capacity for a 30 day period. We may at any time elect to have our treating and gathering capacity increased subject to cost indemnifications to ETC. Additional treating and gathering capacity requests must be in at least 25
MMcfd and 5 MMcfd increments, respectively. In addition, we must furnish to ETC information that reasonably demonstrates that our projected production for the five years after expansion is sufficient to warrant the costs to create the expanded
treating and gathering capacity. The incremental volume increases in treating and gathering capacity shall be subject to marginal increases in treating fees. Pursuant to the agreements, we have access up to 150 MMcfd of firm transportation on
ETCs system or the pipelines of its affiliates or subsidiaries from the tailgate of the treating facility to Katy Hub. We have the option to sell and ETC has the obligation to buy, up to 150 MMcfd of our Hilltop production at delivery points
upstream of ETCs gathering and treating facilities. We do not have an obligation to deliver to ETC volumes in excess of 150 MMcfd, but should ETC elect to purchase such excess volumes, purchases will be subject to the treating and gathering
expansion terms set forth in the agreements.

Registration Obligation and Penalties

On
November 29, 2007, Gastar USA, a wholly owned subsidiary of Gastar Exploration Ltd., sold $100 million aggregate principal amount of 123/4% Senior Secured Notes at an issue price of 99.50%. Gastar USA is obligated to prepare and file with the SEC within 150 days of the issue date of the 123/4% Senior Secured Notes, or April 27, 2008, a registration statement to exchange the 123/4% Senior Secured Notes for registered, publicly tradable notes that have substantially identical terms as the 123/4% Senior Secured Notes. Gastar USA is to use its best efforts to cause the registration statement to be declared effective within 240 day of the issue date of the 123/4% Senior Secured Notes, or July 24, 2008. Gastar USA has agreed to offer exchange notes in exchange for the 123/4% Senior Secured Notes as soon as is practicable after the registration statement has become effective, unless prohibited by law or SEC policy, and to file a shelf registration
statement for the resale of the 123/4% Senior Secured Notes if Gastar USA cannot consummate the exchange offer within 290 days
of the date of the issuance of the 123/4% Senior Secured Notes, or September 12, 2008, and in certain other circumstances.
In the event Gastar USA fails to meet its registration obligations as set forth above, Gastar USA has agreed to pay liquidated damages to the holders of the 123/4% Senior Secured Notes in the form of additional cash interest payments on the 123/4% Senior Secured Notes equal to 0.25% per annum for the first 90-day period, increasing to a maximum of 0.50% per annum for each subsequent 90-day period.

New Accounting Pronouncements

Fair Value Measurements.In September 2006, the
Financial Accounting Standards Board (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 US GAAP. As a result of SFAS No. 157 there is now a common definition of fair value to be used throughout US GAAP. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007, and interim periods within those years. The FASB also has issued Staff Position FAS 157-2 (FSP No. 157-2), which delays the effective date of SFAS No. 157 for
nonfinancial assets and liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually), until fiscal years beginning after November 15, 2008. The Company does
not expect the adoption of SFAS No. 157 or FSP No. 157-2 to have a material impact on the Companys consolidated financial position, results of operations or cash flows.

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

Business Combinations.    In December 2007, FASB issued SFAS No. 141, Business Combinations
(SFAS No. 141R), which creates greater consistency in the accounting and financial reporting of business combinations. This statement is effective for fiscal years beginning after December 15, 2008. The Company does not expect
the adoption of SFAS No. 141R to have a material impact on the Companys consolidated financial position, results of operations or cash flows.

The Fair Value Option for Financial Assets and Financial Liabilities.    In February 2007, FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial
LiabilitiesIncluding an Amendment of FASB Statement No. 115 (SFAS No 159), which permits an entity to choose to measure certain financial assets and liabilities at fair value. SFAS No. 159 also revises provisions of
SFAS No. 115 that apply to available-for-sale and trading securities. This statement is effective for fiscal years beginning after November 15, 2007. The Company does not expect the adoption of SFAS No. 159 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, 2007, a 10% change in the prices received for natural gas production would have had an approximate $3.4 million impact on our revenues. We have entered into hedge transactions to mitigate our commodity pricing risk. See Note
9Commodity Hedging Contracts to our consolidated financial statements, beginning on page F-1, for additional information on our hedging activities.

Interest Rate Risk

The carrying value of our debt approximates fair value. At December 31, 2007, we had
approximately $133.3 million in principal amount of long-term debt, all of which was at a fixed interest rate. A 10% fluctuation in interest rates would have no impact on 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 2007, our Australian activities consisted of capital expenditures totaling approximately $15.2 million. We have no plans in the foreseeable future to implement hedges or
financial instruments to manage international currency changes.

|Item 9A. | Controls and Procedures
|-------- | -----------------------

Evaluation of Disclosure Controls and Procedures

As required by Rule 13a-15(b) under the Exchange Act, 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 Annual Report on Form 10-K. Based upon that evaluation, our principal executive officer and principal financial officer concluded that our
disclosure controls and procedures were effective as of December 31, 2007, to ensure that information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate,
to allow timely decisions regarding required disclosure and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC.

Notwithstanding the foregoing, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that
all control issues and instances of fraud, if any, within our Company have been detected. These inherent limitations include the realities that judgments in decision making can be faulty and that breakdowns can occur because of a simple error or
mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the control. Moreover, the design of any system of controls is also based in part upon
certain assumptions about the likelihood of future events.

Managements Report on Internal Control over Financial Reporting

Our disclosure controls and procedures are designed to ensure that information required to be disclosed by us in the reports that are filed or submitted
under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commissions rules and forms. These disclosure controls and procedures include controls and procedures
designed to ensure that information required to be disclosed under the Exchange Act is accumulated and communicated to our management on a timely basis to allow decisions regarding required disclosure. Under the supervision and with the
participation of our management, including our chief executive officer, chief financial officer, and chief accounting officer, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of
December 31, 2007 based on criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

Our internal control over financial reporting includes policies and procedures that (1) pertain to maintenance of records that, in reasonable
detail, accurately and fairly reflect transactions and dispositions of assets;

##### Index to Financial Statements

(2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally
accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of our management and board of directors; and (3) provide reasonable assurance regarding prevention or timely detection of
unauthorized acquisition, use, or disposition of assets that could have a material effect on the financial statements.

Due to its inherent
limitations, internal control over financial reporting may not prevent or detect misstatements and, even when determined to be effective, can only provide reasonable, not absolute, assurance with respect to financial statement preparation and
presentation. Projections of any evaluation of effectiveness to future periods are subject to risk that controls may become inadequate as a result of changes in conditions or deterioration in the degree of compliance.

Based on the assessment, our management has concluded that our internal control over financial reporting was effective as of December 31, 2007 and
provides reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with generally accepted accounting principles. The results of managements
assessment were reviewed with the Audit Committee of our Board of Directors.

Our internal control over financial reporting has been
audited by BDO Seidman, LLP, an independent registered public accounting firm, as stated in their report which is included herein.

in our internal control over financial reporting that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

Board of Directors and Shareholders

Gastar Exploration Ltd.

Houston, Texas

We have audited Gastar Exploration
Ltd.s (the Company) internal control over financial reporting as of December 31, 2007, based on criteria established in Internal ControlIntegrated Frameworkissued by the Committee of Sponsoring Organizations of
the Treadway Commission (the COSO Criteria). The Companys management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial
reporting, included in the accompanying Item 9A, Managements Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the effectiveness of internal control over financial reporting of
the Company based on our audit.

We conducted our audit 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 effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an
understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included
performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A companys internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for
external purposes in accordance with generally accepted accounting principles. A companys internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable
detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with
generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding
prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Gastar Exploration Ltd. maintained, in all material respects, effective internal control over financial reporting as of December 31,
2007, based on the COSO Criteria.

We also have audited, in accordance with the standards of the Public Company Accounting
Oversight Board (United States), the consolidated balance sheets of Gastar Exploration Ltd. and subsidiaries as of December 31, 2007 and 2006 and the related consolidated statements of operations, stockholders equity, and cash flows for
each of the three years in the period ended December 31, 2007 and our report dated March 14, 2008 expressed an unqualified opinion thereon.

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, 2007.

Code of Ethics

We adopted a Code of Ethics on December 15, 2005. A copy of our Code of Ethics for all
employees was filed as an exhibit to our Registration Statement on Form S-1/A on December 22, 2005 and is available on our 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. The Whistleblower procedure adopted by the Audit Committee is available on our website at www.gastar.com.

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. Penner 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. On July 16, 2007, we announced that Mr. Robert D. Penner had been appointed a director and a member of the Audit
Committee, bringing us into compliance with the American Stock Exchange Company Guide Rule.

Notwithstanding our temporary 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.

Compensation Discussion and Analysis

The following Compensation Discussion and Analysis explains our
compensation objectives, philosophy and practices with respect to our Chief Executive Officer, Chief Financial Officer and Chief Operating Officer, who are referred to as named executive officers. These individuals are our only executive officers.

Compensation Philosophy

Our
compensation programs for our 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 performance that is critical to our success;
| | - |  | -------------------------------------------------------------------------



| |  |  | Align the interests of our named executive officers and our shareholders by motivating our named executive officers to increase shareholder value and rewarding them
based on operational and financial success and when shareholder value increases; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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

Our executive compensation is structured to achieve these goals through our mix of short-term cash payments and long-term equity compensation.

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 operational successes, common share performance and creation of shareholder value. The terms of the named
executive officers employment, including their compensation and other benefits, are set forth in employment agreements, described below.

Role
of the Remuneration Committee, its Consultant and Management

Executive compensation is the responsibility of the Remuneration
Committee (for purposes of this analysis, the Committee). The Committee operates under a written charter, or the Terms of Reference, adopted by the Board of Directors. Abby F. Badwi, Robert D. Penner and John M. Selser Sr.
are members of the Board of Directors and members of the Committee. Mr. Badwi is the Committee Chairman. Each member of the Committee qualifies as an independent director under the American Stock Exchange listing standards and under the
Exchange Act.

The aim of the Committee is to award and compensate officers and employees in a manner which provides incentives for the
enhancement of shareholder value, for the successful implementation of the Companys business plan and for continuous improvement in corporate and personal performance. The compensation program is based on a pay-for-performance philosophy.

The Committee reviews and recommends the compensation philosophy and guidelines for the Company, which include reviewing the compensation
philosophy and guidelines (a) for executive management, for recommendation to the Board for its consideration and approval, and (b) relating to all employees, including annual salary and incentive policies and programs, and material new
benefit programs or material changes to existing benefit programs.

During 2007, the Committee engaged Thomas J. Reno &
Associates, Inc. (TJR), a consulting firm experienced in executive compensation, which has access to national compensation surveys and our compensation information. TJRs responsibilities include



| |  |  | Providing recommendations on compensation based on review of the compensation of our peer group (as described below);
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | Gathering and analyzing publicly available proxy data from the peer group and other peer group data;
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | Analyzing pay survey data and analyses provided by our management;
| | - |  | ------------------------------------------------------------------



| |  |  | Reviewing and advising on the performance measures to be used in bonus formulas and equity awards; and
| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | Reviewing and advising on target bonus levels, actual year end bonus calculations and the design and size of equity awards.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------

These peer companies reviewed by TJR included Abraxas Petroleum Corp., Exploration Company of Delaware, Gasco Energy Inc., GMX Resources Inc., Harvest
Natural resources Inc., NGAS Resources Inc., Toreador Resources Corp., Transmeridian Exploration Inc. and Warren Resources Inc. TJR reviewed the amount or form of executive and director compensation, as well as periodic detailed analyses of peer
group executive salaries, cash bonus awards and other incentive compensation bonus awards and other incentive compensation awards, such as stock options and restricted common stock grants. This information is used by the Committee to insure that
base salaries and other benefits are reasonable and competitive with those offered by our peer group to their executives.

Our Chief Executive Officer also plays an important role in the executive compensation process and is
closely involved in assessing the performance of our named executive officers and making recommendations regarding base salary, bonus targets, performance measures and weighting and equity compensation for these executive officers. The compensation
of our Chief Financial Officer and Chief Operating Officer is determined by the Committee, after receiving the recommendations of the Chief Executive Officer as to what he considers to be fair compensation for our named executive officers. The
recommendations are based on an assessment of the Chief Financial Officers and Chief Operating 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 Committee that are related to the Chief Financial Officers and Chief Operating Officers compensation. The compensation of our Chief Executive Officer is determined
by the Committee. In determining the compensation of the Chief Executive Officer, the 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.

Our Chief
Financial Officer also plays an important role in our executive compensation process. Our Chief Financial Officer makes recommendations to the Committee regarding the structure of the annual cash bonus awards program and the size of such awards.
These recommendations are drawn from our Chief Financial Officers previous work experience and informal surveys of the annual cash bonus programs of other similar sized companies and other oil and natural gas companies.

Benchmarking of Compensation

When making
compensation decisions, we also look to the compensation of our named executive officers relative to the compensation paid to similarly-situated executives at other organizations that are similar in size and operations to us. During 2007, TJR
provided us with competitive compensation data from our peer group as well as business and technical considerations. In 2007, we used three primary resources to identify competitive compensation relevant to our named executive officers:



| |  |  | TJR;
| | - |  | ----



| |  |  | 2007 U.S. Energy Compensation Survey; and
| | - |  | -----------------------------------------



| |  |  | SEC disclosure data for similarly sized organizations within the natural gas and oil industry.
| | - |  | ----------------------------------------------------------------------------------------------

Third-party survey data, such as that provided by TJR and information from other resources and industry contacts, is considered when evaluating external
competitiveness. We use this data to ensure that we are maintaining a level of compensation that is both commensurate with our size and sufficient to retain personnel we consider essential. In reviewing comparative data, we do not engage in
benchmarking for the purpose of establishing compensation levels relative to any predetermined point. In the Committees view, third-party survey data provides insight into external competitiveness but is not an appropriate single basis for
establishing compensation levels. This is primarily due to the differences in the size of comparable companies and the lack of sufficient appropriate matches to provide statistical relevance. Our preference is that performance, rather than third
party survey data, should drive executive compensation. The Committee seeks the input of our Chief Executive Officer in evaluating the performance of all of our executive officers, excluding himself. Our Chief Financial Officer assists in the
gathering of information regarding the employment market assessment.

In the processes used by the Committee to establish and adjust
executive compensation levels, third party-survey data is considered, along with performance, experience and the potential of the individual to contribute to the Companys operations and growth. The Committee can exercise both positive and
negative discretion in relation to the compensation awards and its allocation between cash and non-cash awards. The Committee has the authority to approve, deny and suggest alternative compensation packages.

Elements of Executive Compensation and Rationale

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. The agreements with Messrs. Porter and Gerlich set forth, among other things, annual compensation, and adjustments thereto, minimum bonus payments, termination
provisions, fringe benefits, termination and severance provisions. The agreements automatically renew annually; however, they may be terminated at any time with or without cause. The Company and Jeffery C. Pettit, our Chief Operating Officer,
entered into a letter agreement on August 21, 2008. The letter agreement sets forth, among other things, Mr. Pettits initial base salary, a guaranteed 2007 bonus, fringe benefits, such as vacation and medical insurance coverage, and
severance provisions for his at will employment, which may be terminated at any time by us or Mr. Pettit with or without cause. See Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table for
additional information on employment agreement to the named executive officers.

Base Salary.Base salary
represents the fixed element of the named executive officers cash compensation. The base salary reflects economic consideration for each individuals level of responsibility, expertise, skills, knowledge, experience and performance. Base
salaries for our named executive officers are reviewed annually. Each of our named executive officers initial annual salary is set for the terms of their respective employment agreement but may be adjusted upward or downward at each
anniversary date of each officers employment at the discretion of the Committee. The base salary amounts for Messrs. Porter and Gerlich have been set at $450,000 and $275,000 respectively. Mr. Pettits letter agreement with us set
his initial base salary at $285,000. A description of the material terms of each named executive officers employment agreement is provided in Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards
TableEmployment Agreements.

In 2007, the Committee made no changes to the base salary amounts for any of our named executive
officers, based on the Committees determination that the existing base salaries were competitive and appropriate in light of the named executive officers tenure with the Company and the overall level of corporate activity.

Annual Cash Bonus Awards.Our cash bonus awards reflect our philosophy to pay for performance. These awards provide our
named executive officers, as well as our other employees on the same basis, with an opportunity to earn an annual cash bonus based on an evaluation of individual performance and the Company achieving certain operational and financial performance
targets. At the beginning of each year, the Committee approves a target cash bonus pool, which equals the sum of a bonus target percentages of each employee times each employees annual salary. The targeted bonus percentages for named executive
officers was determined using the experiences of the members of the Committee, the review of cash bonus awards of named executive officers with other companies, many of which have substantially more resources to evaluate such matters, and on
informal surveys with other companies. At the end of each year, the Companys performance is evaluated against certain specific operational and financial target criteria. Each criterion is given a certain weighting, with a majority of the
weighting allocated to operational factors. In developing the appropriate target criteria and their respective weightings, the Committee analyses the relative importance of each of the target criteria to our business strategy for the upcoming fiscal
year. Criteria and weightings used in 2007 were:



| |  |  | Achieving a target average annual production per day for the year (20%);
| | - |  | ------------------------------------------------------------------------



| |  |  | Achieving a target total Company proved reserves (20%);
| | - |  | -------------------------------------------------------



| |  |  | Achieving specific Texas average (per Mcfe) finding and development costs and controllable lifting costs (20%);
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | Achieving specific overall per Mcfe average cash general and administrative expense (5%);
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | Achieving specific level of operating cash flow (25%); and
| | - |  | ----------------------------------------------------------



| |  |  | Accomplishing certain financing goals during the year (10%).
| | - |  | ------------------------------------------------------------

##### Index to Financial Statements

Performance above or below the targeted criteria results in a calculated increase or decrease in the cash
bonus pool. Certain minimum targets are also established for the individual criteria which, if not met, results in no bonus being earned for that criterion. At the end of the year, an approved bonus pool is calculated based on the bonus pool
criteria accomplishments. The amount of the calculated bonus pool is subject to adjustment and final approval by the Committee. As a result of our 2007 operational and financial performance, we surpassed all of the performance targets except one
operational criterion. This would have resulted in a calculated bonus pool of an amount equal to 250% of the target cash bonus pool. In its discretion, the Committee reduced the calculated bonus pool to an amount equal to 150% of the target cash
bonus pool.

For 2007, the Committee determined that Mr. Porters target cash bonus would be 50% of his annual compensation based
on the reasons described above. As a result of our operational and financial performance, he was awarded a cash bonus of $337,500, or 75% of his base salary in 2007, which is equal to 150% of his target bonus. He received an amount based on the same
formula applicable to all employees of 1.5 times targeted cash bonus. His 2007 bonus reflected his leadership in raising significant debt and equity capital to finance our expanded exploration activities in East Texas and Australia, as well as the
Company meeting and exceeding the operational and financial targets described above.

For 2007, the Committee determined that
Mr. Gerlichs target cash bonus would be 35% of his annual compensation based on the reasons described above. As a result of our operational and financial performance, he was awarded a cash bonus of $145,000, or 53% of his base salary in
2007, which is equal to 150% of his target bonus. He received an amount based on the same formula applicable to all employees of 1.5 times targeted cash bonus. His 2007 bonus recognized his financial skills used to successfully raise significant
debt and equity capital to finance our expanded exploration activities in East Texas and Australia, providing the leadership in the successful completion of the Sarbanes Oxley compliance process, including IT compliance, as well as the Company
meeting and exceeding the operational and financial targets described above.

For 2007, the Committee determined that
Mr. Pettits target cash bonus would be 25% of his annual compensation based on the reasons described above. In 2007, he was awarded a cash bonus of $40,000, or 38% of his base salary, pro rated for the period he was employed by us during
the year. He received an amount based on the same formula applicable to all employees of 150% of targeted cash bonus. His 2007 bonus recognized his contribution to the overall improvement in operational activities since becoming our Chief Operating
Officer, as well as the Company meeting and exceeding the operational and financial targets described above.

In 2007, a significant factor
in determining the 150% of multiplier to calculate the level of cash bonus awards was the Companys substantially improved exploration and operational results, as compared to those of 2006, and the substantial increase in year end proved
reserves.

Cash Retention Payment Award.    The Company is involved in a number of litigation matters, where an
adverse ruling could have a material adverse effect on us. Retention of our named executive officers and all other employees has become a meaningful consideration in our overall compensation package. As a result of the uncertainties created by this
situation, the Board of Directors at the Committees recommendation approved cash retention payment awards for the named executive officers, as well as all other employees. Each named executive officer and other current employees of the Company
who are still employed by the Company on January 31, 2009 will receive a cash retention payment equal to their target bonus. The cash incentive bonus awards for Messrs. Porter, Gerlich and Pettit are calculated to be $225,000, $96,250 and
$71,250.

Stock-based Compensation.We believe that equity compensation is the most effective means of
linking compensation provided to our named executive officers with long-term operational success and increases in shareholders value. The Board of Directors has discretionary authority to determine granting and vesting periods of stock option
and restricted common share grants. We use stock-based compensation as a long-term vehicle because we believe:



| |  |  | Stock-based compensation align the interests of named executive officers and our other employees with those of the shareholders;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



59



---

##### Table of Contents

##### Index to Financial Statements

| |  |  | The vesting period incorporated into stock-based compensation fosters a longer term perspective necessary for staff retention, stability and continuity; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Stock-based compensation helps to provide a longer term balance to our overall compensation program.
| | - |  | ----------------------------------------------------------------------------------------------------

Historically, we used stock options as the equity compensation vehicle. In mid-2007, we began using grants of restricted common shares to employees as a
compensation vehicle, rather than stock options. This change occurred in response to the Committees judgment that to retain and attract qualified employees we needed a more definable deferred monetary incentive than was being provided by stock
option grants. Currently, restricted common shares are granted to new hires at the time of employment and to all others, including our named executive officers, in the first half of the year, as determined by the Committee. The 2007 grants of
restricted common shares vest one-third on the second, third and fourth anniversaries of the grant. This vesting schedule was based on the Chief Executive Officers belief that a vesting schedule that delayed the initial vesting of shares until
the second anniversary of the grant provides more incentive for retention of employees than might be provided by a shorter initial vesting period.

Although we do not anticipate using stock option grants for employees in the future, we have utilized stock option grants as the equity compensation vehicle for our directors, although this may change in the future.

In July 2007, Messrs. Porter and Gerlich received a restricted common share grant for an aggregate of 225,000 and 137,500 of our restricted common
shares, respectively. The restricted common shares granted to Messrs. Porter and Gerlich were part of a larger annual grant of restricted common shares to employees designed to retain and provide additional employee incentives.

The number of restricted common shares is calculated by multiplying 50% times the employees base salary. For 2007, TJR recommended that the target
bonus percentage be 100% of base salary based on their review of the compensation practices of our peer companies. The Committee determined that the target bonus percentage for 2007 would be 50% of each employees base salary. In making this
determination, the committee also considered other factors, such as Mr. Porters leadership and his success during the year in raising significant debt and equity capital to finance our expanded exploration activities in East Texas and
Australia, Mr. Gerlichs contribution during the year in raising significant equity capital to finance our expanded exploration activities in East Texas and Australia and the Companys successful completion and compliance with the
Sarbanes Oxley Act, and Mr. Pettits guidance in the overall improvement in our operational activities.

Mr. Pettit joined
us as Chief Operating Officer in August 21, 2007. As a part of his employment package, Mr. Pettit received a restricted common share grant for an aggregate of 112,500 restricted common shares.

Perquisites.The named executive officers are eligible to participate in the same comprehensive benefits as are offered to
all full-time employees. Additionally, Mr. Porters employment agreement provides that we will pay or reimburse him up to $25,000 for his membership dues in 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. During 2007, we paid, or reimbursed, Mr. Porter a total of
$73,138. See footnote 3 to Summary Compensation Table for details of payment of perquisites to Mr. Porter in 2007.

During
2007, other than the comprehensive benefits offered to all full-time employees, neither Mr. Gerlich nor Mr. Pettit received any perquisites having a value over $10,000 in aggregate.

Post Termination or Change of Control Compensation and Benefits

On March 23, 2007, our Board of Directors approved a change of control severance plan, as amended February 15, 2008, covering all employees,
including the named executive officers. The purpose of the severance plan is to promote stability and continuity of management and employees in the event a change of control transaction should occur. Pursuant to the terms of their respective
employment agreements and the provisions of our change of control severance plan, Messrs. Porter, Gerlich and Pettit 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 or as set forth in the Employee Change of Control Severance Plan. See Narrative Disclosure to Summary
Compensation Table and Grants of Plan-Based Awards Table and Potential Payments upon Termination or Change of Control below.

|(1) | The fair values of stock option awards are determined by using the Black-Scholes-Merton valuation model as of the date of grant, as set forth in SFAS 123R. See Note 8Equity
Compensation PlansDetermining Fair Value under SFAS 123R to our consolidated financial statements, which begins on Page F-1, for a discussion of assumptions made in the valuation of option awards. The fair value at the date of grant is
amortized using the graded-vesting method, which recognizes compensation costs over the requisite service period for each separately vesting tranche of an award as though the award were, in substance, multiple awards. The amounts shown
in these column represent the stock-based compensation expense for the years ended December 31, 2007 and 2006, prior to a 5.0% deduction for estimated forfeitures, attributable to stock options and restricted common share grants that was
attributable to all stock options and restricted common shares granted to the named executive officer and outstanding during each respective year that is recognized by us in that respective year. During 2007, total fair value attributable to
restricted common share grants to Messrs. Porter, Gerlich and Pettit as of the date of grant was $495,000, $203,500 and $187,875, respectively. During 2006, total fair value attributable to stock options granted to Messrs. Porter and
Mr. Gerlich as of the date of grant was $1,677,646 and $1,035,262, respectively.

|(2) | Grant date fair value of restricted common share awards is equal to the closing price of our common shares on the day prior to the date of grant times the number of common shares
granted. This fair value is used to determine the stock-based compensation expense, as shown in our consolidated financial statements. The amounts shown in these column represent the stock-based compensation expense for the year ended
December 31, 2007 prior to a 5.0% deduction for estimated forfeitures, attributable to restricted common share grants that was attributable to all restricted common shares granted to the named executive officer and outstanding during each
respective year that is recognized by us in that respective year. During 2007, total fair value attributable to restricted common share grants to Messrs. Porter, Gerlich and Pettit as of the date of grant was $281,250, $171,875 and $140,625,
respectively.

Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table

The following is a
narrative of our various compensation plans and the general terms of each:

2002 Stock Option Plan.    The
Companys 2002 Stock Option Plan was approved and ratified by the Companys shareholders in July 2002. It authorizes the Companys Board of Directors to issue stock options to directors, officers, employees and consultants of the
Company and its subsidiaries to purchase a maximum of 25.0 million common shares. Stock option grant expirations vary between five and 10 years. The vesting schedule has varied from two years to four years but generally has occurred over a
four-year period at 25% per year beginning on the first anniversary date of the grant. Stock options issued pursuant to the Companys 2002 Stock Option Plan have an exercise price determined by the Board of Directors, but that exercise
price cannot be less than the market price on the date immediately prior to the date of grant as reported by any stock exchange on which the Companys common shares are listed. If a stock option granted under the Companys 2002 Stock
Option Plan expires or terminates for any reason in accordance with the terms of the Companys Stock Option Plan, the unpurchased common shares subject to that stock option become available for other stock option grants.

In April 2004, the Board of Directors amended the provisions of the 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. As of December 31, 2007, stock option grants covering the issuance of 10,173,750 common shares were
outstanding under the 2002 Stock Option Plan.

2006 Gastar Long-Term Stock Incentive Plan.On June 1,
2006, the Companys shareholders approved the 2006 Gastar Long-Term Stock Incentive Plan. The 2006 Gastar Long-Term Stock Incentive Plan authorizes the Companys Board of Directors to issue stock options, stock appreciation rights, bonus
stock awards and any other type of award established by the Committee which is consistent with the Plans purposes to directors, officers and employees of the Company and its subsidiaries covering a maximum of 5.0 million common shares.
The contractual life and vesting period for a grant will be determined by the Board of Directors at the time grant is awarded. The vesting period for restricted common stock grants during 2007 was over four years, with one-third vesting on the
second, third and fourth anniversaries of the date of grant. As of December 31, 2007, only grants covering the issuance of 1,096,000 restricted common shares were outstanding under the 2006 Gastar Long-Term Stock Incentive Plan.

All stock options incorporate the following features:



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



| |  |  | Grant price 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 that is determined by the Board of Directors.
| | - |  | --------------------------------------------------------------------------------------

In 2006 and a portion of 2007, stock options were granted to new hires at the time of employment and to all other employees, including our named
executive officers, around the time of our annual meeting of shareholders. The Board of Directors has discretionary authority to determine granting and vesting periods of stock options. Typically, vesting periods have been over a four-year period
with 25% vesting on the first, second, third and fourth anniversary dates. Certain stock options granted in 2006 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.

Pursuant to our incentive plans, the Board of Directors has designated the Remuneration Committee as the entity to administer
the granting of stock options, restricted common stock grants and other forms of stock-based compensation. Grants are determined by the Committee, based on the recommendations of our Chief Executive Officer, except in the case of grants awarded to
the Chief Executive Officer. In determining a grant to named executive officers, the Committee has taken 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 current individual performance and corporate performance.

Employee Change of Control Severance
Plan.    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 change of control
severance plan does not change the specific, non-change of control severance payments in place under the existing employment agreements 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 change of control 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 set forth in the change of control severance plan:



|                                         |  |                         |  |                       |  
|---------------------------------------- |  | ----------------------- |  | --------------------- | -
|                                         |  | SeverancePeriodin
Years |  | TargetBonusPercentage |  
|Chief Executive Officer                  |  | 3.00                    |  | 50                    | %
|Chief Financial Officer                  |  | 2.50                    |  | 35                    | %
|Vice President (Chief Operating Officer) |  | 2.00                    |  | 25                    | %

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.

Employment Agreements.    We 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. The agreements with Messrs. Porter and Gerlich
set forth, among other things, annual compensation, and adjustments thereto, minimum bonus payments, fringe benefits, termination and severance provisions. The agreements renew annually; however, they may be terminated at any time with or without
cause. Jeffery C. Pettit, our Chief Operating Officer, entered into an employment letter agreement on August 21, 2008. The letter agreement sets forth, among other things, Mr. Pettits initial base salary, a guaranteed 2007 bonus,
fringe benefits and severance provisions for Mr. Pettits, which may be terminated at any time by us or Mr. Pettit with or without cause.

Mr. Porters employment agreement provides that he is entitled to an annual bonus in an amount that 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.

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

##### Table of Contents

upon a showing of Reasonable Cause, as defined in his employment agreement. If he is terminated by us for any reason other than cause, he will
receive severance pay of two years total compensation. The severance payment will consist of the payment of Porters W-2 compensation earned in the calendar year coincident with or immediately preceding Porters termination of employment,
payable over the appropriate number of weeks after termination of employment (the Severance Pay Period) and continuation of health insurance for Mr. Porter and his family at our expense during the Severance Pay Period. If
Mr. Porter dies during the Severance Pay Period, severance pay and health benefits will continue for the benefit of his eligible beneficiary during the remainder of the Severance Pay Period.

Mr. Gerlichs employment agreement provides that the Committee may on a yearly basis, or more frequently, award Mr. Gerlich a
discretionary bonus or bonuses based not only on the positive results of our operations and business, but Mr. Gerlichs contribution as Chief Financial Officer. Such bonuses may take the form of cash compensation, the award of stock or
stock options, royalty rights or otherwise. Mr. Gerlichs employment agreement also provides that his employment shall terminate (i) without notice, upon his death; (ii) without notice, upon his Disability, as defined
in his employment agreement; (iii) upon two months written notice to us 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 agreement 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 us for
any or no reason, with or without cause and (vi) or by us without prior notice, upon a showing of Reasonable Cause, as defined in his employment agreement. If he is terminated by us for any reason other than cause, he will receive
severance pay of two years annual gross salary, exclusive of bonuses received, stock options granted or exercised, or other non cash compensation. The severance payment will be calculated on the basis of his then current annual salary, to be earned
in Mr. Gerlichs then current employment year coincident with or immediately preceding the notice of termination of employment, payable in equal amounts over 100 weeks (the Severance Pay Period). There will be continuation of
health insurance for Mr. Gerlich and his family at our expense during the Severance Pay Period. If Mr. Gerlich dies during the Severance Pay Period, severance pay and health benefits will continue for the benefit of his eligible
beneficiary during the remainder of the Severance Pay Period.

Mr. Pettits employment agreement provides that he or us may
terminate his employment and any time, with or without cause. If he is terminated by us for cause (as defined in his employment agreement), he will not be eligible for severance or other compensation; except for, accrued annual salary to the date of
termination. If he is terminated by us without cause during his first two years, he will receive 1.0 times his annual salary plus stock options or restricted common shares vested prior to the date of termination. If he is terminated by us without
cause after his second year of employment, he will receive 1.5 times his annual salary plus stock options or restricted common shares vested prior to the date of termination. Any severance or other compensation shall be paid over the termination
period. We may terminate Mr. Pettits employment if a disability results in Mr. Pettit being unable to work for more than 90 days; provided, however, this will not apply to injury occurring while performing job duties.

Option Exercises and Stock Vested

During the year ended December 31, 2007, no restricted common shares that were granted to the named executive officers vested, and no stock options were exercised by the named executive officers. The named
executive officers have no other outstanding stock awards other than those shown above.

Potential Payments Upon Termination or Change of Control

The table below discloses the amount of compensation
and/or other benefits due to the named executive officers in the event of their termination of employment, including, but not limited to, in connection with a change in control. The amounts shown assume that such termination was effective as of
December 31, 2007, and thus include amounts earned through such date and are estimates of the amounts which would be paid to the named executive officers upon their respective termination. The actual amounts to be paid out can only be
determined at the time the executive is terminated.

|(5) | The Companys Employee Change of Control Severance Plan provides that 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 (the
gross-up payment). To determine Mr. Porters amount of the gross-up payment, Mr. Porters base amount was calculated using the five-year average of his compensation for the years 2002-2006. In the case of
Mr. Gerlich, the amount is calculated using the two-year average of his W-2 earnings for 2006 and his annualized salary plus paid bonus for 2005, as his employment with the Company commenced in mid-2005. The payments received in connection with
the change of control in excess of a named executive officers base amount is considered an excess parachute payment as provided by Section 280G of the Code. If the total of all parachute payments is
equal to or greater than three times the base amount, the amount of the excess parachute payment will be subject to the excise tax. In making the calculation, the following assumptions were used: (a) the change of control occurred on
December 31, 2007, (b) the closing price of our stock was $1.25 on such date, (c) the excise tax rate under Section 4999 of the Code is 20%, the federal income tax rate is 35%, the Medicare rate is 1.45%, the adjustment to
reflect the phase-out of itemized deductions is 1.05%, and there is no state or local income taxes, (d) no amounts will be discounted as attributable to reasonable compensation, (e) all cash severance payments are contingent upon a change
of control, (f) the presumption required under applicable regulations that the equity awards granted were contingent upon a change of control could be rebutted.

|(6) | The Gastar Employee Change of Control Severance Plan provides that if there is a transaction that results in a change of control and the surviving entity does not assume or convert
the awards, then such awards will immediately vest. For the purpose of this disclosure, we have assumed the surviving entity does not assume or convert the awards. The amount shown is the product of the number of restricted shares held by the named
executive officer times the closing price of our common shares on December 31, 2007, or $1.25 per common share.

The
employment agreements of Messrs. Porter, Gerlich and Pettit generally use the following terms:

Reasonable Cause means any of
the following (a) an act or omission that amounts to dishonesty, disloyalty, fraud, deceit, gross negligence, willful misconduct or recklessness, including the willful violation of any of our policies or procedures; (b) a felony
conviction; (c) a breach of any material term of the employment agreement; (d) the refusal to perform any services that the named executive officer is required to perform under the employment agreement; or (e) with respect to
Mr. Porters agreement only, an act that is determined by the vote of two-thirds of the shareholders to constitute Reasonable Cause or to be detrimental to the best interests of the Company.

Disability means the inability to perform the functions essential to the named executive
officers position with or without accommodation during a continuous 12 month period, due to physical or mental illness of the named executive officer. The date of disability is the last day of the 12 month period. Successive periods of illness
or injury that are due to the same or related causes are considered one period of disability unless the named executive officer returns to work full-time for three successive months. Except that Mr. Pettits employment agreement defines
disability as the inability to perform all duties of his job for more than ninety days.

Mr. Gerlichs employment
agreement describes a change of control as a change of control as a result of a sale of all or substantially all of our assets, purchase of over 50% of our stock, or through merger, consolidation, corporate restructuring or
otherwise.

The Employee Change of Control Severance Plan generally uses the following terms:

A change of control means (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.

Involuntary Termination means any termination of employment that occurs within two years following a Change of
Control and which (1) does not result from a voluntary resignation by the covered employee (except for Good Reason), (2) results from a resignation by the Covered Employee for Good Reason, but (3) does not result from a termination by
the Company for Cause, as a result of the covered employees death or Disability, or because the covered employee declined to accept an offer of comparable employment from the successor employer.

Good Reason means the occurrence of any of the following after a Change of Control: (1) relocating the covered employees place of
employment without his consent to a place outside of the 35-mile radius of his previous place of employment, (2) reducing the covered employees annual base salary or materially reducing his benefits that were provided immediately prior to
the Change of Control, (3) the Companys material breach of the Employee Change of Control Severance Plan, (4) a purported termination of the covered employees employment for Cause by the Company that does not otherwise comply
with the terms of the Employee Change of Control Severance Plan, or (5) a substantial reduction in the covered employees position or responsibilities. In certain circumstances, the occurrence of one of these events within six months prior
to the Change of Control may be Good Reason.

Our Employee Change of Control Severance Plan provides that if any payment made,
or benefit provided, to or on behalf of a covered employee pursuant to the plan or otherwise (Payments) results in a covered employee being subject to the excise tax imposed by Section 409 of the Code (or any successor or similar
provision) (Excise Tax), we shall, as soon as administratively practicable, pay such covered employee an additional amount in cash (the Additional Payment) such that after payment by the covered employee of all taxes,
including, without limitation, any taxes imposed on the Additional Payment, such Covered Employee retains an amount of the Additional Payment equal to the Excise Tax imposed on the Payments. Such determinations shall be made by our independent
certified public accountants.

Mr. Porters employment agreement contains a 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 agreement further provides that, for a period of two years
after his termination of employment with us for a reason other than reasonable cause, (six months if terminated for reasonable cause), Mr. Porter shall not, directly or indirectly, compete with us.

Mr. Gerlichs employment agreement provides that, unless specifically pre-approved by the Chief
Executive Officer in writing, which approval may not be unreasonably withheld, Mr. Gerlich will not directly compete (as defined in the employment agreement) with us for a period of two years following his termination of employment.

Mr. Pettits employment agreement contains a confidentiality provision applicable both during the term of his employment and following his
termination of employment. Pursuant to the confidentiality provision, he agrees to hold in confidence and not disclose any confidential and proprietary 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.

|(1) | 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. The fair values of stock option awards were
determined in accordance with SFAS 123R by using the Black-Scholes-Merton valuation model as of the date of grant. See Note 8Equity Compensation PlansDetermining Fair Value under SFAS 123R to our consolidated financial statements ,
which begins on Page F-1, for a discussion of assumptions made in the valuation of option awards. The amounts shown in this column represents the stock-based compensation expense, prior to a 5.0% deduction for estimated forfeitures, attributable to

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 authorization 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, 2007, we had stock options outstanding to purchase
10,173,750 common shares pursuant to the 2002 Stock Option Plan, 5,127,916 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, restricted 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 grants 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. If any restricted common shares granted under the 2006 Gastar Long-Term Stock Incentive Plan that are unvested at the time of a grantees termination of employment, the
unvested shares will be canceled with a corresponding reduction of common shares outstanding.

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 and employees 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. Stock 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, 2007, a total of 1,096,00 restricted common shares had been granted to employees and were outstanding under the 2006 Gastar
Long-Term Stock Incentive Plan. As of December 31, 2007, there were no stock options outstanding 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 Note 13Related Party Transactions to our consolidated financial statements, which
begin 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 American Stock Exchange director independence standards. J. Russell Porter, as our President and Chief
Executive Officer, is not considered to be independent. The Board has determined that each of the members of the Audit Committee, the Remuneration Committee, the Nomination Committee, Governance Committee and the Reserve 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 American Stock Exchange director independence standards.

The audit fees for the years ended
December 31, 2007 and 2006 were primarily for professional services rendered in connection with the audit of our consolidated financial statements, fees related to our compliance with the Sarbanes-Oxley Act of 2002, together with services
rendered in connection with quarterly reviews of financial statements and various documents filed with various governmental agencies. Audit related fees primarily include the review of certain documents filed with the SEC, the 123/4% Senior Secured Notes financing and related offering circular, and other accounting related matters. Fees for tax services were
for services related to tax compliance, including the preparation of tax returns. During 2007 and 2006, there were no other accounting fees.

The Audit Committee pre-approves all audit and non-audit services provided by our independent registered public accounting firm prior to its engagement with respect to such services. In addition to separately approved services, the Audit
Committees pre-approval policy provides for pre-approval of all audit and non-audit services provided by our independent registered public accounting firm.

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. (the Company) and subsidiaries as of
December 31, 2007 and 2006, and the related consolidated statements of operations, shareholders equity and cash flows for each of the three years in the period ended December 31, 2007. In connection with our audit of the financial
statements, we have also audited the schedule listed in Item 15(a)(2) of this Form 10-K. These financial statements and the schedule are the responsibility of the Companys management. Our responsibility is to express an opinion on these
financial statements and the schedule 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. An audit 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 presentation of the financial statements and
schedule. 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, 2007 and 2006, and the results of their operations and their cash flows for each of the three years
in the period ended December 31, 2007, in conformity with accounting principles generally accepted in the United States of America.

Also, in our opinion, the schedule when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth herein.

As more fully described in Note 2 to the consolidated financial statements, effective January 1, 2006, the Company adopted the provisions of SFAS
No. 123(R), Share-Based Payment.

We also have audited, in accordance with the standards of the Public Company Accounting
Oversight Board (United States), Gastar Exploration Ltd.s internal control over financial reporting as of December 31, 2007, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission (COSO) and our report dated March 14, 2008 expressed an unqualified opinion thereon.

GASTAR EXPLORATION LTD. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Description of Business

Gastar Exploration Ltd.
(the Company) is 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 (CBM). The Company is pursuing unconventional natural gas exploration in the deep Bossier play in the Hilltop area in East Texas. The Companys 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 USA), Gastar Exploration Texas, Inc., Gastar Exploration Texas LP, Gastar Exploration Texas LLC, Gastar Exploration New South Wales, Inc.,
Gastar Exploration Victoria, Inc. (collectively, Guarantors) and Gastar Power Pty Ltd. (Gastar Power). All significant intercompany accounts and transactions have been eliminated in consolidation.

Foreign Currency Translation and Exchange

The
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$). Our Australian properties represent CBM wells that are in the exploration or pre-production stage. Although we have exploration and development operations in Australia, we currently have no commercial production operations there.
Limited operations are conducted in Canadian dollars (CDN$). 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 consolidated statement 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 U.S.
subsidiaries are maintained in U.S. dollars. The accounts of Gastar Power are maintained in Australian dollars. Translation gains and losses recorded on investments in subsidiaries that are of a permanent nature are not tax effected.

Cash and Cash Equivalents

Cash and cash equivalents, which includes 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 $85.9 million and
$40.7 million as of December 31, 2007 and 2006, 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

Accounts receivable are reported net of the allowance for doubtful accounts. The allowance for doubtful accounts is determined based on a review of the
Companys 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.

The following table indicates deferred charges and related accumulated amortization as of the dates indicated:

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.

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 is
added to costs subject to depletion calculations.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



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.

Capitalized Interest

The Company capitalizes interest based on the cost of major development projects, which are excluded from current depreciation, depletion and amortization
calculation. Capitalized interest costs were approximately $1.9 million for 2007. The Company reported no capitalized interest for 2006 or 2005.

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 123/4% Senior Secured Notes, the convertible senior debentures and the subordinated unsecured notes payable are fixed rate debt, but the interest rates are not materially different than current prevailing market rates
based on relative maturities, and as such, their carrying value approximates fair value for such instruments.

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, 2007 and 2006.

Asset
Retirement Obligation

The Company accounts for its asset retirement obligations in accordance with Statement of Financial
Accounting Standards (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 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, 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.

Earnings or Loss per Share

In accordance with the provisions of SFAS No. 128, Earnings per Share (SFAS No. 128), basic
earnings or loss per share is computed on the basis of the weighted average number of common shares outstanding, excluding unvested restricted common shares, during the periods. Diluted earnings or loss per share is computed based upon the weighted
average number of common shares outstanding, excluding unvested restricted common shares, 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, restricted common shares and
warrants and the as if converted method for the convertible senior debentures.

Stock-Based Compensation

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

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 stock-based 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 SFAS
No.123R, Share-Based Payment (SFAS No. 123R), using the modified-prospective method. Under that method, stock-based compensation cost for 2006 included: (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 No. 123(R). Compensation expense is recognized using the graded-vesting method,

which recognizes compensation costs over the requisite service period for each separately vesting tranche of an award as though the award were, in substance,
multiple awards. The adoption of SFAS No. 123R had an immaterial effect on 2006 financial results.

The table below reflects the
pro-forma impact of stock-based compensation on the Companys net loss and loss per share had the Company applied SFAS No. 123 to stock options granted prior to January 1, 2003 that vested in 2005:

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.

Hedging Program

The Company accounts for derivatives and hedging activities in accordance with SFAS Statement No. 133, Accounting for Derivative Instruments and
Certain Hedging Activities, as amended, which requires entities to recognize all derivative instruments as either assets or liabilities in the balance sheet at their respective fair values. For derivatives designated as hedges, changes in the
fair value are either offset against the change in fair value of the assets and liabilities through earnings, or recognized in accumulated other comprehensive income until the hedged item is recognized in earnings.

The Company utilizes derivative instruments in the form of natural gas costless collar price arrangements in order to manage price risk associated with
future natural gas production. Such agreements are accounted for as hedges using the deferral method of accounting. Gains and losses resulting from these transactions, recorded at market value, are deferred and recorded in accumulated other
comprehensive income as appropriate, until recognized as operating income in the Companys consolidated statements of operations as the physical production hedged by the contracts is delivered.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



The Company is required to assess the effectiveness of all our derivative contracts at inception and
at every quarter-end. If open contracts cease to qualify for hedge accounting, mark-to-market accounting is utilized and changes in the fair value of open contracts are recognized in the consolidated statements of operations. Not qualifying for
hedge accounting may cause volatility in net income. Fair value is assessed, measured and estimated by obtaining forward commodity pricing, credit adjusted risk-free interest rates and estimated volatility factors. In addition, forward price curves
and estimates of future volatility factors are used to assess and measure the effectiveness of our open contracts at the end of each period. The fair values we report in our consolidated financial statements change as estimates are revised to
reflect actual results, changes in market conditions or other factors, many of which are beyond our control.

The net cash flows related to
any recognized gains or losses associated with these hedges are reported as oil and gas revenues and presented in cash flows from operations. If the hedge is terminated prior to expected maturity, gains or losses are deferred and included in income
in the same period as the physical production hedged by the contracts is delivered.

The conditions to be met for a derivative instrument
to qualify as a cash flow hedge are the following: (i) the item to be hedged exposes the Company to price risk; (ii) the derivative reduces the risk exposure and is designated as a hedge at the time the derivative contract is entered into;
and (iii) at the inception of the hedge and throughout the hedge period there is a high correlation of changes in the market value of the derivative instrument and the fair value of the underlying item being hedged.

When the designated item associated with a derivative instrument matures, is sold, extinguished or terminated, derivative gains or losses are recognized
as part of the gain or loss on sale or settlement of the underlying item. When a derivative instrument is associated with an anticipated transaction that is no longer expected to occur or if correlation no longer exists, the gain or loss on the
derivative is recognized in income to the extent the future results have not been offset by the effects of price changes on the hedged item since the inception of the hedge.

Restricted Cash

The Company is required to maintain cash balances that are restricted by
provisions of certain banking agreements to support commodity hedging transactions. Restricted cash is invested in short term instruments at market rates; therefore, the carrying value approximates fair value. Such cash is included as Other Assets
and is excluded from cash and cash equivalents in the consolidated balance sheets.

Reclassifications

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

Recent Accounting Pronouncements

Fair
Value Measurements.In September 2006, the Financial Accounting Standards Board (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 US GAAP. As a result of SFAS No. 157, there is now a common definition of fair value to be used throughout US GAAP. SFAS
No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those years. The FASB has also issued Staff Position FAS 157-2 (FSP No. 157-2), which
delays the effective date of SFAS No. 157 for nonfinancial assets and liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis (at

least annually), until fiscal years beginning after November 15, 2008. The Company does not expect the adoption of SFAS No. 157 or FSP
No. 157-2 to have a material impact on the Companys consolidated financial position, results of operations or cash flows.

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

Business Combinations. In December 2007, FASB issued SFAS No. 141 (revised 2007), Business Combinations (SFAS No. 141R), which replaces SFAS No. 141 (SFAS No. 141). This
statement retains the fundamental requirements in SFAS No. 141 that the acquisition method of accounting (which SFAS No. 141 called the purchasemethod) be used for all business combinations. SFAS No. 141R also establishes
principles and requirements for how the acquirer: (a) recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, and any noncontrolling interest in the acquiree; (b) recognizes and
measures the goodwill acquired in the business combination or a gain from a bargain purchase; and (c) determines what information to disclose to enable users of the financial statements to evaluate the nature and financial effects of the
business combination. SFAS No. 141R is effective as of the beginning of an entitys fiscal year that begins after December 15, 2008. Early adoption is prohibited. The Company is currently evaluating the impact of adopting SFAS
No. 141R, which also requires acquisition transaction costs to be expensed as incurred rather than capitalized as a direct cost of the acquisition, as transaction costs are not considered an element of the fair value of the company acquired.
Depending upon the size, nature and complexity of a future acquisition transaction, such transaction costs could be material to the Companys results of operations.

3. Drilling Advances

Drilling advances 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. 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 are being amortized over the three-year term of the drilling contract agreement on a straight line basis as an increase to capitalized natural gas and oil property costs.

At December 31, 2007, unproved properties not being amortized consisted of drilling in
progress costs and acreage acquisition costs of $21.1 million and $48.7 million, respectively. As of 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.

For the years ended December 31, 2007, 2006 and 2005, the results of managements
ceiling test evaluation resulted in an impairment of the U.S. proved properties of $28.5 million, $56.3 million and $8.7 million, respectively. The December 31, 2007 U.S. proved property impairment was reported in the second quarter of 2007
utilizing a weighted average natural gas price of $5.72 per Mcf. Management determined that impairment was not required on the Australian properties at December 31, 2007, 2006 or 2005.

In May 2007, the Company sold a portion of its undeveloped natural gas and oil acreage in the Hilltop area of East Texas for approximately $66.5 million
in cash, net of transaction costs of approximately $1.2 million,

resulting in a gain on sale of $38.5 million. The Company follows the full cost method of accounting, which typically does not allow for gain on sale
recognition involving less than 25% of the reserves in a given cost center. Reducing the U.S. full cost pool by the $66.5 million in net sales proceeds would have resulted in an approximate 39% reduction in capitalized cost with no change in proved
reserves, thus significantly altering the relationship of capitalized costs to proved reserves. The significant reduction in the full cost pool was deemed to be an out-of-the-ordinary situation, and the Company determined
that gain recognition on the sale of unproven property was the proper accounting treatment.

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 and 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 was 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 16,
Commitments and ContingenciesLitigation.

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 bore interest, payable monthly commencing July 1, 2005, 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 year ended December 31, 2005 show the effect on the Companys consolidated results of
operations as if the GeoStar Acquisition had occurred at the beginning of the period presented. The pro forma results are the result of combining the statement of operations of the Company with the statement 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 statement of revenues

123/4% Senior Secured Notes due 2012

On November 29, 2007, Gastar USA, a wholly owned subsidiary of Gastar Exploration Ltd.,
(Parent) sold $100.0 million aggregate principal amount of 123/4% Senior Secured Notes due December 1, 2012
(123/4% Senior Secured Notes) at an issue price of 99.50%. Approximately $76.7 million of the $92.5 million net
proceeds from the offering were used to repay the then outstanding senior secured notes, with the remaining net proceeds to be used for general corporate purposes. The 123/4% Senior Secured Notes mature on December 1, 2012.

GASTAR EXPLORATION LTD. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



Interest is payable, semi-annually on
June 1 and December 1, in cash on the principal amount at an annual rate of 123/4%. The annual effective interest
rate, after amortization of the debt discount and fees paid to establish the 123/4% Senior Secured Notes, is 14.89%. The 123/4% Senior Secured Notes are fully and unconditionally guaranteed jointly and severally by Gastar USA, the Parent and all of the
Parents existing and future material domestic subsidiaries. The 123/4% Senior Secured Notes and the guarantees rank equal
in right of payment with all existing and future senior indebtedness of Gastar USA and the Guarantors and senior in right of payment to any future subordinated indebtedness of Gastar USA and the Guarantors, as applicable. The 123/4% Senior Secured Notes and the guarantees are secured by a lien on Gastar USAs principal domestic oil and gas properties and
other assets that secure Gastar USAs revolving credit facility (Revolving Credit Facility), subject to certain exceptions. Pursuant to the terms of an intercreditor agreement, the lien securing the 123/4% Senior Secured Notes is contractually subordinated to (i) the lien that secures the Revolving Credit Facility and
(ii) certain hedging obligations of Gastar USA. Consequently, the 123/4% Senior Secured Notes and the guarantees are
effectively subordinated to Gastar USAs and the Guarantors secured obligations, including the Revolving Credit Facility, to the extent of the value of the assets securing such obligations.

At any time prior to June 1,
2010, Gastar USA may redeem the 123/4% Senior Secured Notes in whole or in part at a redemption price equal to 100% of the
principal amount plus the applicable premium. The applicable premium is the greater of (i) 1.0% of the 123/4% Senior
Secured Notes being redeemed and (ii) the excess of (A) the present value at such time of (1) redemption price of 123/4% Senior Secured Notes as of June 1, 2010 (without regard to accrued and unpaid interest) plus (2) all required interest payments due on 123/4% Senior Secured Notes through June 1, 2010, computed using a discount rate equal to the Treasury Rate plus 50 basis points, over (B) the principal amount of 123/4% Senior Secured Notes. At any time and from time to time prior to June 1, 2010, Gastar USA may redeem up to 35% of the aggregate principal amount of the 123/4% Senior Secured Notes with the net cash proceeds of one or more equity offerings at 112.750% of the aggregate principal amount,
plus accrued and unpaid interest. On or after June 1, 2010, Gastar USA may redeem the 123/4% Senior Secured Notes during
the 12-month periods beginning on June 1 of the years and at a premium as set forth below:



|                                      |  |            |

|2012                                  |  | 100.000    | %

If a change of control of Parent, as
defined in the indenture governing the 123/4% Senior Secured Notes, occurs prior to December 1, 2008, Gastar USA may elect
to redeem all, but not less than all, of the 123/4% Senior Secured Notes at the price of 112.75%, plus accrued and unpaid
interest. If a change of control occurs under the indenture, the holders of the 123/4% Senior Secured Notes have the right to
require Gastar USA to repurchase the 123/4% Senior Secured Notes at 101% of principal amount, plus accrued and unpaid interest.

Within 30 days of an asset sale greater than $10.0
million, excluding Wyoming property sales, Gastar USA will offer to use the net proceeds to repurchase that portion of the 123/4% Senior Secured Notes at a premium as set forth below:

Gastar USA is obligated to prepare and file
with the Securities and Exchange Commission (SEC) within 150 days of the issue date of the 123/4% Senior Secured
Notes, or April 27, 2008, a registration statement to exchange the 123/4% Senior Secured Notes for registered, publicly
tradable notes that have substantially identical terms as the 123/4% Senior Secured Notes. Gastar USA is to use its best efforts
to cause the registration statement to be declared effective within 240 day of the issue date of the 123/4% Senior Secured
Notes, or July 24, 2008. Gastar USA has agreed to offer exchange notes in exchange for the 123/4% Senior Secured Notes as
soon as is practicable after the registration statement has become effective, unless prohibited by law or Securities and Exchange Commission (SEC) policy, and to file a shelf registration statement for the resale of the 123/4% Senior Secured Notes if Gastar USA cannot consummate the exchange offer within 290 days of the date of the issuance of the
123/4% Senior Secured Notes, or September 12, 2008, and in certain other circumstances. In the event Gastar USA fails to
meet its registration obligations as set forth above, Gastar USA has agreed to pay liquidated damages to the holders of the 123/4% Senior Secured Notes in the form of additional cash interest payments on the 123/4% Senior Secured Notes equal to
0.25% per annum for the first 90-day period, increasing to a maximum of 0.50% per annum for each subsequent 90-day period. The Company intends to file a registration statement with the SEC on or before April 27, 2008 and to use its
best efforts to have such statement effective on or before September 12, 1008.

The 123/4% Senior Secured Notes contain certain covenants, that among other things, limit Gastar USAs and the Guarantors ability to: (i) incur additional indebtedness; (ii) pay distributions on, or
repurchase or redeem Company equity interests; (iii) make certain investments; (iv) incur liens; (v) enter into certain transactions with affiliates; and (vi) sell assets or consolidate or merge into other companies.
Notwithstanding the above, Gastar USA may incur up to $25.0 million of indebtedness under the Revolving Credit Facility (see below) and such additional amounts of 123/4% Senior Secured Notes or indebtedness subordinate to the 123/4% Senior
Secured Notes; provided that Gastar USAs consolidated cash flow to fixed charges for the most recent four quarters giving the effect of the incurrence at the beginning of such four-quarter-period is at least 2.0 to 1.0. As of December 31,
2007, the Company was in compliance with all debt covenants.

Revolving Credit Facility

On November 29, 2007, concurrent with the closing of the 123/4% Senior Secured Notes, Gastar USA entered into a Revolving Credit Facility providing for an initial first priority lien maximum borrowing base of $19.4
million at December 31, 2007, of which no amounts were outstanding. The borrowing base is to be redetermined at least semiannually, using the lenders usual and customary criteria for natural gas and oil reserve valuation. If at any time
the outstanding credit extended under the Revolving Credit Facility exceeds the lesser of the aggregate commitments or the applicable borrowing base, the deficiency will be required to be amortized in three monthly installments, and until the
deficiency is eliminated, increases in some applicable interest rate margins apply.

The lenders commitment under the
Revolving Credit Facility will be limited to a maximum of $250 million outstanding at any one time, subject to applicable borrowing base limitations. Borrowings under the Revolving Credit Facility bears interest, at Gastar USAs election, at a
prime rate or Eurodollar rate, plus in each case an applicable margin. The applicable interest rate margin varies from -0.75% to 0.0% in the case of borrowings based on the prime rate and from 1.5% to 2.25% in the case of borrowings based on the
Eurodollar rate, depending on the utilization level in relation to the borrowing base. At December 31, 2007, the prime rate and the Eurodollar rate were 7.25% and 4.70%, respectively. At closing, Gastar USA paid a commitment fee of $73,000. In
addition, an annual commitment fee, ranging from 0.375% to 0.50% depending on borrowing base utilization, is payable on the unused portion of each lenders commitment; provided, however, such rate as to the portion of the available commitment
allocable to the lender on the basis of its percentage share as a lender shall be reduced if certain cash deposit investments are maintained with the lender.

8. Equity Compensation Plans

Share-Based Compensation Plans

2002 Stock Option Plan.    The
Companys 2002 Stock Option Plan was approved and ratified by the Companys shareholders in July 2002. It authorizes the Companys Board of Directors to issue stock options to directors, officers, employees and consultants of the
Company and its subsidiaries to purchase a maximum of 25.0 million common shares. Stock option grant expirations vary between five and 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. Stock options issued pursuant to the Companys 2002 Stock Option Plan have an exercise price determined by the Board of Directors, but that exercise
price cannot be less than the market price on the date immediately prior to the date of grant as reported by any stock exchange on which the Companys common shares are listed. If a stock option granted under the Companys 2002 Stock
Option Plan expires or terminates for any reason in accordance with the terms of the Companys Stock Option Plan, the unpurchased common shares subject to that stock option become available for other stock option grants.

In April 2004, the Board of Directors amended the provisions of the 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. As of December 31, 2007, stock option grants covering the issuance of 10,173,750 common shares were outstanding under the 2002 Stock Option Plan.

2006 Gastar Long-Term Stock Incentive Plan.    On June 1, 2006, the Companys shareholders approved
the 2006 Gastar Long-Term Stock Incentive Plan. The 2006 Gastar Long-Term Stock Incentive Plan authorizes the Companys Board of Directors to issue stock options, stock appreciation rights, bonus stock awards and any other type of award
established by the Committee which is consistent with the Plans purposes to directors, officers and employees of the Company and its subsidiaries covering a maximum of 5.0 million common shares. The contractual life and vesting period for
a grant will be determined by the Board of Directors at the time grant is awarded. The vesting period for restricted common stock grants during 2007 was over four years, with one-third vesting on the second, third and fourth anniversaries of the
date of grant. As of December 31, 2007, only grants covering the issuance of 1,096,000 restricted common shares were outstanding under the 2006 Gastar Long-Term Stock Incentive Plan.

Determining Fair Value under SFAS No. 123R

In determining fair value for stock option grants pursuant to SFAS No. 123R, the Company utilized the following assumptions:

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

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

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

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

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

Expected Forfeitures.    The Company utilized a forfeiture rate of 5% for
2007 and 2006 in determining initial compensation expense, based on forfeitures of all unvested stock option as a percentage of all stock option grants calculated at the beginning of the year.

The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes-Merton valuation pricing model. The table below
summarizes the number of stock options granted and the assumptions for the stock options granted for the periods indicated:



|                         |  |                                 |   |  |           |   |  |         |

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 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 and May 23, 2007, Chesapeake acquired an additional 5,000,000 common shares and 1,757,195 common shares, respectively, in private placement transactions. As of December 31, 2007, Chesapeake owned 33,908,836 common
shares, or 16.3% of the Companys outstanding common shares.

For Australian income tax purposes, the Company has net operating loss carry forwards of
approximately $21.8 million. There is currently no time limit on the utilization of tax losses in Australia. Ability to use Australian tax losses is based on statutory tests.

In June 2006, the FASB issued FIN 48. FIN 48 requires that the Company recognize the financial statement benefit of a tax position only after
determining that the relevant tax authority would more likely than not sustain the position following an audit. For a tax position meeting the more likely than not threshold, the amount recognized in the financial statements is the largest benefit
that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant tax authority. The Company did not have any unrecognized tax benefits and there was no effect on our financial condition or results of
operations as a result of implementing FIN 48.

It is expected that the amount of unrecognized tax benefits may change in the next twelve
months; however, the Company does not expect the change to have a significant impact on financial condition or results of operations. As of December 31, 2007, the Company has no unrecognized tax benefits that if recognized would affect the
effective tax rate.

The Company is subject to examination of income tax filings in the U. S., various state jurisdictions and the foreign
jurisdictions of Canada and Australia for the tax periods 2000 and forward due to the Companys continued loss position in such jurisdictions.

Estimated interest and penalties related to potential underpayment on any unrecognized tax benefits are classified as a component of general and administrative expense in the consolidated statement of operations. The Company has not
recorded any interest or penalties associated with unrecognized tax benefits.

15. Earnings or Loss per share

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

Litigation

The Company is party to various litigation matters arising out of the normal course of business. 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.

Arbitration and Litigation with GeoStar Corporation and Affiliates

Arbitration against GeoStar and Affiliates. On October 18, 2006, in connection with 10 wells to be drilled in Victoria, Australia on the
jointly owned EL 4416 exploration license operated by GeoStar Corporation, the Company sent a letter to GeoStar demanding the arbitration of certain disputed issues and interpretations under a Participation and Operating Agreement (POA)
with GeoStar and its subsidiaries. Among other items, the claims the Company presented for resolution in arbitration include claims relating to 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 the Company believes are not reasonable or within industry standards. The Company has also requested that GeoStars Australian subsidiary
provide a record title assignment of the Companys beneficial interests in EL 4416, the exploration license in the Gippsland Basin property in Victoria, Australia. The Company has approximately $9.9 million invested in EL 4416 as of
December 31, 2007. GeoStar contends that the Company is not entitled to the record title assignment notwithstanding the Companys significant investment. The Companys former Chairman of the Board is a major shareholder and President
of GeoStar. GeoStar has voluntarily dismissed its efforts to enjoin the arbitration from proceeding and has answered and asserted counterclaims. Those counterclaims include (a) a request for a declaration that the Company has no rights to
participate in brown coal projects in EL 4416, (b) a request for a declaration that the Company did not earn an interest under the POA as to certain wells the Company drilled in East Texas, (c) breach of contract for failure to pay certain
bills and expenses related to West Virginia properties, and (d) breach of contract to pay for employee expenses and services. The Company, which denies and intends to vigorously defend each of these counterclaims, contends that it has
participation rights to the full scope of EL 4416 under the terms of the POA and that the Texas wells were drilled on lands to which the Company obtained rights under separate 2005 Purchase and Sale Agreements. The three-member arbitration panel has
been appointed and an arbitration hearing is currently scheduled for June 2008.

Gastar Exploration, Ltd., Gastar Exploration Texas,
Inc., f/k/a First Texas Development, Inc., Gastar Exploration Texas LLC, f/k/a Bossier Basin, LLC, and Gastar Exploration Texas LP, f/k/a First Source Gas, LP v. GeoStar Corporation, First Source Texas, Inc., First Source Bossier, LLC, and First
Texas Gas, LP. In July 2007, the Company filed a lawsuit in Robertson County, Texas against GeoStar and affiliates seeking relief in connection with the failure by GeoStar and its affiliates to execute formal assignments of certain leases
that were omitted from the schedule of leases attached to the assignments executed by GeoStar affiliates in June 2005

pursuant to Purchase and Sale Agreements covering Texas properties of GeoStar and its affiliates. The lawsuit asks the court to decree that in the
transaction evidenced by the Purchase and Sale Agreements, affiliates of the Company acquired title to all properties in Texas in which GeoStar and its affiliates owned an interest and that GeoStar and its affiliates are obligated to execute formal
assignments with regard to all such leases. GeoStar and one of its affiliates have filed a challenge to the Texas courts jurisdiction. Additionally, GeoStar and certain of its affiliates have also filed counterclaims in this litigation
substantively identical to the counterclaims filed in the Harris County lawsuit described in the next paragraph and in the section below entitled GeoStar Look Back Developments.

Gastar Exploration Ltd., Gastar Exploration USA, Inc. f/k/a First Sourcenergy Wyoming Inc., Gastar Exploration New South Wales, Inc., f/k/a First
Sourcenergy Group, Inc., Gastar Exploration Victoria, Inc. f/k/a First Sourcenergy Victoria, Inc.,, Gastar Exploration Texas, Inc., f/k/a First Texas Development, Inc., Gastar Exploration Texas LLC, f/k/a Bossier Basin, LLC, and Gastar Exploration
Texas LP, f/k/a First Source Gas, LP v. GeoStar Corporation. In July 2007, the Company and affiliates filed a lawsuit in the District Court of Harris County, Texas against GeoStar in connection with GeoStars failure to deliver to the
Company and its affiliates the corporate records of the Company and to its affiliates that have been retained by GeoStar. Representatives of the Company and its affiliates previously demanded return of the corporate records retained by GeoStar, but
GeoStar failed to return the records. The lawsuit asks the court to decree that the Company and its affiliates are entitled to possession of the corporate records and order their return to the Company and its affiliates. The lawsuit also seeks
recovery of actual and punitive damages, costs, and attorneys fees. GeoStar has now delivered some of the requested records that are the subject of this litigation to the Company, and the Company has requested that GeoStar deliver additional
records.

Gastar Exploration, Ltd., Gastar Exploration Texas, Inc., f/k/a First Texas Development, Inc., Gastar Exploration Texas LLC,
f/k/a Bossier Basin, LLC, and Gastar Exploration Texas LP, f/k/a First Source Gas, LP v. GeoStar Corporation, First Source Texas, Inc., First Source Bossier, LLC, and First Texas Gas, LP. In August 2007, the Company and certain affiliates
filed a second lawsuit in Robertson County, Texas, seeking a declaratory judgment that the Company and its affiliates have complied with the Look-Back provisions of the Texas Purchase and Sale Agreements that are the subject of the other Robertson
County, Texas lawsuit referenced above, that the Company and its affiliates have complied with the provisions of the Texas Purchase and Sale Agreements relating to the drilling of wells, and that GeoStar and its affiliates hold no farm-in interest
in properties owned by the Companys affiliates. GeoStar and one of its affiliates have filed a challenge to the Texas courts jurisdiction. The defendants also have generally denied the allegations made in the lawsuit. Additionally,
GeoStar and certain of its affiliates have also filed counterclaims in this litigation substantively identical to the counterclaims filed in the Harris County litigation described above in the discussion of that litigation and below in the section
entitled GeoStar Look Back Developments.

Although it previously contested jurisdiction in Texas, GeoStar (together with
certain of its affiliates) has as of January 2008 asserted counterclaims in all three Texas lawsuits similar to claims GeoStar had previously asserted and dismissed in the Michigan lawsuit described below. The counterclaims relate to Texas
properties that were the subject of Purchase and Sale Agreements entered into in 2005, under which the Company acquired the interests of GeoStar-affiliated entities in properties in Texas. Specifically, GeoStar claims that the Company breached the
Purchase and Sale Agreements by failing to provide information in connection with contingent Look Back payments under provisions of the Purchase and Sale Agreements, and by failing to make payments allegedly due to GeoStar under the
Look-Back provisions, arising out of alleged changes in reserves following the sale of the Texas properties in June 2005. Although requesting only damages in an unspecified amount, GeoStar contends in the counterclaim that it would have been
entitled under the Purchase and Sale Agreements to approximately 1.7 billion shares of Gastar stock. GeoStar also claims that the Company failed to timely comply

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



with provisions of the Purchase and Sale Agreements relating to the drilling of 20 wells on the properties conveyed under the Purchase and Sale Agreements
and by failing to drill and test at least two wells in the Travis Peak formation in Texas, allegedly entitling GeoStar to unspecified damages related to a farm-in interest under which it was allegedly entitled to the right to drill, complete, and
operate wells in the Travis Peak formation on certain acreage. The Company intends to vigorously defend the counterclaims. The Company has moved to abate the Harris County proceedings with respect the counterclaims in favor of the earlier-filed
Robertson County proceedings. Certain information that may be relevant to this matter is set forth below in the section below entitled GeoStar Look Back Developments.

GeoStar Corporation and West Virginia Gas Corporation v. Gastar Exploration Ltd. and J. Russell Porter. On July 27, 2007, the Company
was served with a lawsuit filed by GeoStar and one of its affiliates, West Virginia Gas Corporation, in federal court in Saginaw, Michigan. GeoStar asserted a broad range of claims against the Company and its current chief executive officer, J.
Russell Porter.

GeoStar initially sought in the Michigan suit to enjoin the Companys arbitration against GeoStar and its affiliates.
GeoStar has now voluntarily dismissed that request with prejudice.

GeoStar also claims in the Michigan suit that the POA was cancelled
effective January 1, 2005, and that the parties have operated under oral contracts since that date. GeoStar asserts that the Company has breached the alleged oral contracts by allegedly failing to pay joint interest billings, authorizations for
expenditures, and cash calls relating to operations or proposed operations on EL 4416 in Australia and West Virginia properties, in an unspecified amount exceeding $75,000. GeoStar also claims that the Company has breached alleged agreements to
reimburse GeoStar for various payments and services allegedly performed by GeoStar and its personnel and paid on behalf of the Company by GeoStar. GeoStar claims that the amounts of the payments and the value of the services exceed $10.0 million.
GeoStar alternatively alleges that if there was no contract covering those payments and services, it allegedly is entitled to reimbursement on equitable principles. On January 15, 2008, the federal court granted the Companys motion to
dismiss these claims for failure to state a claim on which relief could be granted. GeoStar filed a motion asking that the Court reconsider that ruling or permit it to replead the claims. On February 8, 2008, the federal court denied the motion
to reconsider but granted GeoStar permission to replead those claims, which it did on February 22, 2008. In repleading those claims, GeoStar has restated the prior claims for oral agreement to reimburse certain expenses or equitable entitlement
to reimbursement of certain expenses, and it specifies a number of items for which GeoStar is allegedly entitled to reimbursement from the Company. GeoStar seeks approximately $17.0 million. The Company filed a response to these claims on
March 7, 2008.

GeoStar also asserted claims in the Michigan lawsuit relating to Texas properties that were the subject of Purchase
and Sale Agreements entered into in 2005. GeoStar has voluntarily dismissed those claims without prejudice from the Michigan lawsuit and re-asserted similar claims in pending litigation in Harris and Robertson Counties, Texas as discussed below
under GeoStar Look Back Developments.

West Virginia Gas Corporation (WVGC), an affiliate of GeoStar, also asserts claims
against the Companys current chief executive officer, alleging that the Company and its current chief executive officer tortiously interfered with an alleged contract between WVGC and certain West Virginia individuals and entities. According
to the lawsuit, these individuals and entities allegedly promised to give their oil, gas, and coalbed methane opportunities in West Virginia and Pennsylvania to WVGC. WVGC alleged that Gastar and its chief executive officer caused those individuals
and entities to establish and use new business entities to allegedly conceal opportunities from West Virginia Gas Corporation and to funnel them to the Company, the Companys chief executive officer and the West Virginia individuals and
entities. On January 15, 2008, the federal court dismissed

these claims to the extent they were brought by GeoStar and to the extent they were brought against the Company. The court denied our chief executives
motions to dismiss WVGCs claim and a motion to reconsider that denial. Our chief executive intends to vigorously defend the claim.

GeoStar Look Back Developments. The Purchase and Sale Agreements between GeoStar and the Company relating to certain East Texas properties acquired by the Company in 2005 (the PSAs) contain a Look Back
provision that is the subject of claims in three of the previously described lawsuits with GeoStar. Under the 2005 PSAs, GeoStar conveyed interests in certain Texas properties to the Company and was paid an agreed $43.5 million in consideration for
the properties (including cash, 8.6 million shares of Company common stock, and promissory notes), subject to certain purchase price adjustments relating to the period prior to closing. The interests conveyed by the PSAs comprise a portion of
the security for the notes and the Guarantees.

Under the Look Back provision, two Look Back payments are to be calculated based in part on
changes in proved and probable reserves attributable to certain of the Companys leasehold interests over certain periods of time ending June 30, 2006 and 2007. If a Look Back payment is due to GeoStar under the PSAs, the PSAs require the
payment to be effected through the issuance of the Companys stock.

The PSAs provide that the calculation of the Look Back payment
shall be based upon reserve estimates reported by Netherland Sewell & Associates, Inc. (NSA), or in certain circumstances, based upon an average of the NSA estimates and estimates obtained by GeoStar from an independent,
professionally certified reservoir engineering firm utilizing the same regulatory requirements and reserve calculation guidelines as those employed by NSA in its estimates. Based on the NSA reserves estimate and the Look Back calculations set forth
in the PSAs, the Company believes that no additional issuance of Company common shares is due GeoStar under the Look Back provision.

On
November 1, 2007, GeoStar informed the board of directors of our Parent that it intended to submit a reserve report for purposes of the June 30, 2006 and 2007 Look Back analyses showing that the gross reserves attributable to the
Companys leasehold interests are substantially greater than those reflected in the NSA reserve reports on which the Companys Look Back analyses were based. On November 7, 2007, GeoStar submitted a reserve report to the Company that
reported a substantially greater reserve estimate than the estimates in the NSA reserve report.

On November 14, 2007, the Company
received a reserve report of T.J. Smith & Company, Inc. (T.J. Smith) as well as a demand letter from GeoStars counsel (the Demand Letter) in which GeoStar asserted a purported right under the PSAs to receive
additional shares of Gastar stock as a Look Back payment. In the Demand Letter, GeoStar asserts that T.J. Smith has estimated that the total proved and probable reserves in the Companys Texas properties attributable to 100% of the working
interest amount to 2.15 trillion cubic feet of gas, a number which is approximately fourteen times more than the proved and probable reserves estimated by NSA, the engineering firm selected by the parties in the PSAs. On the basis of that reserves
estimate, GeoStar asserts in the Demand Letter that it is entitled to a Look Back payment of approximately 1.7 billion shares of Gastar stock, which if issued would constitute approximately 89% of the Companys common equity and would result in
a change in control of the Company under the Companys debt agreements. In the Demand Letter, GeoStar further asserts that if its demand is not met, it will pursue remedies that may include reclaiming operatorship over certain of the
Companys Texas properties, rescission of the PSAs resulting in return of the properties covered by the PSAs and consideration paid, and unspecified injunctive relief. The Company does not believe that GeoStar is entitled to these remedies.

The Company believes that GeoStars assertions are without merit. The Company believes that the T.J. Smith reserve report was
submitted in bad faith and does not meet the requirements of the PSAs because, among



F-37

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



other things, it does not follow the same regulatory requirements and reserve calculation guidelines as those employed by NSA, as required by the terms of
the PSAs. In addition, GeoStar has asserted that the Look Back analysis should be based on changes in reserves attributable to the entirety, or 8/8ths, of the Companys leasehold interests with respect to its Texas properties, rather than on
changes in reserves attributable to GeoStars net revenue interest in those properties as of the effectiveness of the PSAs, as the Company believes. The Company is pursuing discovery of data pertinent to the T.J. Smith report and GeoStars
contentions relating thereto and will continue to evaluate the Companys legal positions and options based on such discovery.

The
Company intends to vigorously defend itself against GeoStars assertions. However, an unfavorable outcome in litigation relating to the Look Back could have a material adverse effect on the Company were GeoStar to obtain issuance of the
requested shares and obtain control of the Company, rescission of the PSAs, or other relief to which it asserted it was entitled in the November demand letter. A change in control of the Company as a result of an issuance of shares to GeoStar may
require the Company to refinance substantially all of its indebtedness under its existing debt agreements, which refinancing may not be obtainable or may not be on terms as favorable as under current debt agreements. Although the Company does not
currently anticipate the need to access the equity capital markets through 2008 to continue its business plan, until these issues are resolved in whole or in significant part, it will be difficult for the Company to raise capital through the sale of
equity.

In 2007, the Company recorded a $1.4 million litigation settlement expense accrual related to a proposed settlement with GeoStar
regarding the various GeoStar arbitration and litigation matters. The settlement proposal was never finalized. At December 31, 2007, the Company had a receivable from GeoStar of approximately $3.7 million that was fully reserved due to the
various litigation matters.

Other Litigation

Navasota Resources L.P. (Navasota) vs. First Source Texas, Inc. (now Gastar Exploration Texas, Inc.), First Source Gas L.P. (now Gastar Exploration Texas LP) and Gastar Exploration Ltd. (Cause No. 0-05-451) District Court of
Leon County, Texas 12th Judicial District. This lawsuit, dated October 31, 2005, contends that the Company breached Navasotas preferential right to purchase 33.33% of the Companys interest in certain natural gas and oil
leases located in Leon and Robertson Counties and sold to Chesapeake Energy Corporation pursuant to a transaction closed November 4, 2005. The preferential right claimed is under an operating agreement dated July 7, 2000. The Company
contends, among other things, that Navasota neither properly nor timely exercised any preferential right election it may have had with respect to the inter-dependent Chesapeake transaction. In July 2006, the District Court of Leon County, Texas
issued a summary judgment in favor of the Company and Chesapeake. Navasota filed a Notice of Appeal to the Tenth Court of Appeals in Waco. Oral argument was heard on September 26, 2007 and the Court of Appeals issued its opinion on
January 9, 2008 reversing the trial courts rulings and rendering judgment in favor of Navasota on all counts. The Company and Chesapeake filed a motion for rehearing on February 6, 2008, and if unsuccessful, will consider filing a
petition for review to the Texas Supreme Court. Pursuant to an agreement between the Company and Chesapeake, any adverse result in this matter should impact only Chesapeakes assigned leasehold interests. While this matter is pending, it is
possible that expenditures incurred, or authorizations for proposed expenditures, for drilling activities on leases which include the disputed interest may remain unpaid or not be authorized by the non-operators asserting competing ownership rights,
which could require the Company to either fund a disproportionate amount of drilling costs at its own risk or postpone its drilling program on affected leases.

Gastar Exploration Texas LP v. John E. McFarlane, et al (Cause No. 0-06-161) 87th Judicial District Court of Leon County, Texas. This suit is to quiet title to an undivided 25% mineral interest under an
oil and gas lease

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



dated December 4, 2003, covering approximately 2,598 gross acres (the Lease). John E. McFarlane and certain other family members
contend that an undivided 25% mineral interest in the lands covered by the Lease are owned in trust by the grandchildren of Fay W. McFarlane and are not covered by the Lease as Gastar claims. McFarlane, et. al., has filed an answer to the
Companys petition and also filed several different motions for summary judgment, which have been denied by the District Court. A day long mediation of this lawsuit occurred on August 24, 2007, but the parties were unable to settle this
matter. The lawsuit is currently in the discovery phase. The existence of unleased mineral interests in this Lease could adversely impact the future development of the Lease. The Company will continue to vigorously pursue this claim.

Spencer D. Plummer, III v. GeoStar Corporation, Classic Star LLC, Gastar Exploration, Ltd., Thom Robinson, Tony Ferguson, and John W. Parrott; In the
United States District Court of Utah, Central Division (Case No. 2:07-CV-00409). This lawsuit was filed on May 24, 2007 initially in Utah state court by Spencer Plummer, or the Plaintiff, in which he asserts breaches of his
Employment Agreement and subsequent Termination Agreement (the Agreements) with his employer, Classic Star, a subsidiary of GeoStar. The Plaintiff claims that he has not received benefits promised under such Agreements, including 699,249
shares of Company stock. The Company is not a party to the Agreements on which Plaintiffs claims are expressly based; however, the Company and Plaintiff are parties to a Stock Option Agreement on which Plaintiff claim to Company stock is
partially based. The Company filed an Answer and Motion to Dismiss for lack of personal jurisdiction in Utah and for Plaintiffs failure to state a claim upon which relief can be granted. Plaintiff filed a Motion to Remand to state court, and
on September 5, 2007, the Court denied Plaintiffs Motion to Remand. Thereafter, the Companys co-defendant, Classic Star LLC, moved to transfer and consolidate the case in a United States Judicial Panel on Multi District Litigation
(MDL Panel) in Kentucky with other cases in which Classic Star LLC is a named defendant. On October 22, 2007, the MDL Panel granted the motion to transfer. The Company is awaiting the Kentucky courts ruling on its Motion to
Dismiss.

Commitments

In March
2008, the Company entered into formal agreements with ETC Texas Pipeline, Ltd. (ETC) for the gathering, treating, purchase and transportation of the Companys natural gas production from Hilltop area of East Texas. These agreements
are effective September 1, 2007 and have a term of 10 years. ETC currently provides us 50 MMcfd of treating capacity and 120 MMcfd of gathering capacity. The Company has the right to request ETC build, at their cost, up to 150 MMcfd of treating
and gathering capacity during the term of the agreement, provided that the Companys production equals 85% of the then existing treating and gathering capacity for a 30 day period. The Company may at any time elect to have its treating and
gathering capacity increased subject to cost indemnifications to ETC. Additional treating and gathering capacity requests must be in at least 25 MMcfd and 5 MMcfd increments, respectively. In addition, the Company must furnish to ETC information
that reasonably demonstrates that its projected production for the five years after expansion is sufficient to warrant the costs to create the expanded treating and gathering capacity. The incremental volume increases in treating and gathering
capacity shall be subject to marginal increases in treating fees. Pursuant to the agreements, the Company has access up to 150 MMcfd of firm transportation on ETCs system or the pipelines of its affiliates or subsidiaries from the tailgate of
the treating facility to Katy Hub. The Company have the option to sell and ETC has the obligation to buy, up to 150 MMcfd of the Companys Hilltop production at delivery points upstream of ETCs gathering and treating facilities. The
Company does not have an obligation to deliver to ETC volumes in excess of 150 MMcfd, but should ETC elect to purchase such excess volumes, purchases will be subject to the treating and gathering expansion terms set forth in the agreements.

Gastar Exploration USA, Inc., other Guarantors and the Company entered into a registration rights agreement. Pursuant to the registration rights agreement, the Company and the Guarantors agreed that they would (1) within 150 days after the date
of original issue of the 123/4% Senior Secured Notes file a registration statement with the SEC to exchange the 123/4% Senior Secured Notes for new notes of the Company having terms substantially identical in all material respects to the notes
(except that the new notes will not contain terms relating to transfer restrictions); (2) use their reasonable best efforts to cause the registration statement to be declared effective within 240 days after the issue date; (3) as soon as
practicable after the effectiveness of the registration statement, offer the new notes to the holders of the notes in exchange for the notes; and (4) keep the exchange offer open for not less than 30 days (or longer if required by applicable
law) after the date notice of the exchange offer is mailed to the holders of the notes. Under existing SEC interpretations, the new notes will be freely transferable by holders other than Company affiliates after the exchange offer without further
registration. In the event Gastar USA fails to meet its registration obligations as set forth above, Gastar USA has agreed to pay liquidated damages to the holders of the 123/4% Senior Secured Notes in the form of additional cash interest payments on the 123/4% Senior Secured Notes equal to 0.25% per annum for the first 90-day period, increasing to a maximum of 0.50% per annum for each subsequent 90-day period.

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 recent value of expected future cash flows. 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

We entered into employment agreements with our President and Chief
Executive Officer and our Chief Financial Officer, effective February 24, 2005 and May 17, 2005, respectively. The agreements set forth, among other things, annual compensation, and adjustments thereto, minimum bonus payments, termination
provisions, fringe benefits, termination and severance provisions. The agreements renew annually; however, they may be terminated at any time with or without cause. We entered into a letter agreement with our Chief Operating

Officer on August 21, 2007. The letter agreement sets forth, among other things, his initial base salary, a guaranteed 2007 bonus, fringe benefits such
as vacation and medical insurance coverage, and severance provisions for his at will employment, which may be terminated at any time by us or him with or without cause.

We also have entered into agreements with these executives, who are acting at the Companys request to be officers of the Company, to indemnify them the fullest 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.

17. Concentration of Risk and Significant Customers

Approximately 80%, 66% and 65% of the Companys revenues for the years ended December 31, 2007, 2006 and 2005, respectively,
were from production from producing wells in the Hilltop area East Texas.

During 2007, ETC and Enserco Energy, Inc. (Enserco)
accounted for 78% and 20% of the Companys natural gas and oil revenues, respectively. During 2006, ETC and Enserco 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. 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.

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 2007 upward revision of previous estimates is primarily attributed to an increase in natural
gas prices and performance revisions. An increase in natural gas prices of approximately 28% from 2006 resulted in an increase in 2007 proved reserves of approximately 3,815 MMcf, with the remaining portion of the increase attributable to upward
performance revisions primarily in the Hilltop area of East Texas. 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 Hilltop area of East Texas.

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.
