QUESTIONS AND ANSWERS ABOUT THE PROXY MATERIAL, ANNUAL MEETING AND VOTING

Why am I receiving these proxy materials?

Our Board is soliciting your proxy to vote at our Annual Meeting because you owned shares of our common stock at the close of business on April 14, 2010, the record date for the Annual Meeting (the “Record Date”), and are therefore entitled to vote at the Annual Meeting.

At the Annual Meeting, our shareholders will be asked to: (1) fix the number of directors from five (5) to six (6) members; (2) elect six (6) members to the Board to serve until our annual meeting of shareholders in 2011 or until their successors are elected and qualified; (3) ratify the Audit Committee’s appointment of BDO Seidman, LLP, as our independent registered public accounting firm for the year ending December 31, 2010; and (4) transact any such other business as may properly be brought before the Annual Meeting or any adjournment or postponement thereof.

The Board unanimously recommends that you vote:

We do not expect any matters to be presented for action at the Annual Meeting other than the items described in this Proxy Statement. By signing and returning the enclosed proxy, however, you will give to the

1

Table of Contents

persons named as proxies discretionary voting authority with respect to any other matter that may properly come before the Annual Meeting, and they intend to vote on any such other matter in accordance with their best judgment.

In addition, our executive management will report on our business and financial performance during fiscal year 2009 and respond to your questions.

How many votes may I cast?

Each of our common shares that you own on the Record Date entitles you to one vote on each matter that is properly brought before the Annual Meeting. You may cast one vote for every common share that you owned on the Record Date.

How many votes can be cast by all shareholders?

As of the Record Date, there were 50,407,642 common shares outstanding and entitled to vote at the Annual Meeting.

Is my vote important?

Your vote is important regardless of how many common shares you own. Please take the time to vote. Please read the instructions below, choose the way to vote that is easiest and most convenient for you and cast your vote as soon as possible.

How many common shares must be present to hold the Annual Meeting?

A quorum of shareholders is necessary for a valid Annual Meeting. The required quorum for the transaction of business at the Annual Meeting is the presence of a holder or holders of not less than 5% of the total outstanding common shares entitled to vote at the Annual Meeting, either present in person or represented by proxy. Abstentions and broker non-votes will be counted for the purpose of determining the presence of a quorum. A broker non-vote occurs if a broker or other nominee of shares does not have discretionary authority and has not received voting instructions with respect to a particular matter.

What are the voting requirements to elect the directors and to approve each of the proposals discussed in this Proxy Statement?

With respect to the election of directors, votes may be cast in favor of or withheld from the election of each nominee. Votes that are withheld from a director’s election will be counted toward a quorum, but will not affect

2

Table of Contents

the outcome of the vote on the election of a director. Abstentions and broker non-votes will have no effect on the outcome of the election of directors, assuming a quorum is present or represented by proxy at the Annual Meeting. With respect to all other matters, abstentions and broker non-votes are not considered to be votes cast and therefore will have no effect on such matters.

How do I vote my common shares?

If you own your common shares as of the Record Date, you may vote by submitting your proxy by mail, by the Internet or in person at the Annual Meeting.

To Vote by Mail. You may vote by completing and signing the proxy card that accompanies this Proxy Statement and promptly mailing it in the enclosed envelope. The common shares you own will be voted according to the instructions on the proxy card that you provide. If you return the proxy card but do not give any instructions on a particular matter described in this Proxy Statement, the common shares you own will be voted in accordance with the recommendations of the Board. In order to be valid and acted upon at the Annual Meeting, your proxy card must be received by our registrar and transfer agent, American Stock Transfer & Trust Company, Attention: Proxy Department, 6201 15^th Avenue, Brooklyn, New York 11219, at least 24 hours before the time of the Annual Meeting or any adjournment thereof, excluding weekends and holidays.

To Vote in Person. If you attend the Annual Meeting, you may vote by delivering your completed proxy card in person or you may vote by completing a ballot. Ballots will be available at the Annual Meeting. Attending the Annual Meeting without completing a ballot will not count as a vote. Submitting a proxy will not prevent a shareholder from attending the Annual Meeting and voting in person.

To vote by the Internet. Go the following Internet address: http://www.proxyvote.com. You may use the Internet to vote your proxy 24 hours a day, seven days a week until 11:59 p.m. (central time) on June 2, 2010. Have your proxy card available, and follow the instructions to obtain your records and create an electronic ballot.

Can I change my vote after I have mailed my proxy card?

Yes. You can change your vote and revoke your proxy at any time before the polls close at the Annual Meeting by doing any one of the following things:

Your attendance at the Annual Meeting alone will not revoke your proxy.

Can I vote if my shares are held in “street name”?

If your common shares are held in a stock brokerage account or by a bank or other nominee, you are considered the beneficial owner of the common shares held in “street name”. As the beneficial owner, you have the right to direct your broker or nominee how to vote your common shares and are also invited to attend the Annual Meeting. However, since you are not the shareholder of record, you may not vote these shares in person at the Annual Meeting unless you obtained a signed proxy from the record holder giving you the right to vote the shares. In order to vote your common shares, you will need to follow the directions your bank or brokerage firm provides you.

Our directors, officers and regular employees may solicit proxies by telephone, e-mail and personal interviews without additional remuneration for these services.

CORPORATE GOVERNANCE

Information about the Board

The Board believes that good corporate governance improves corporate performance and benefits all shareholders. The Canadian Securities Administrators (the “CSA”) have adopted National Policy 58-201 Corporate Governance Guidelines, which provides non-prescriptive guidelines on corporate governance practices for reporting issuers such as us. In addition, the CSA have implemented National Instrument 58-101 Disclosure of Corporate Governance Practices (“NI 58-101”), which prescribes certain disclosure by us of our corporate governance practices.

This section sets out our approach to corporate governance and addresses our compliance with NI 58-101 and the applicable rules and regulations of the NYSE Amex.

Mandate of the Board

The Board is responsible for managing our business affairs. The primary responsibility of the Board is to promote our best interests and the best interests of our shareholders. This responsibility includes: (i) approving annual capital expenditure budgets and general and administrative expense budgets and reviewing fundamental operating, financial and other corporate plans, strategies and objectives; (ii) outlining key operating parameters including debt levels and ratios; (iii) evaluating our performance and the performance of our senior management; (iv) determining, evaluating and fixing the compensation of executive officers; (v) adopting policies of corporate governance and conduct; (vi) considering risk management matters; (vii) reviewing the process of providing appropriate financial and operational information to shareholders and the public generally; and (viii) evaluating

Table of Contents

the overall effectiveness of the Board. The Board explicitly acknowledges its responsibility for our stewardship. The Board reviews with management matters of strategic planning, business risk identification, succession planning, communications policy and integrity of internal control and management information systems. The Board fulfills its responsibilities through regular and special meetings.

Current Members of the Board

The Board currently is comprised of five members whose names and committee memberships are set forth below. The Board has determined that the members of the Board, with the exception of Mr. Porter, have no material relationship with us (either directly or as partners, shareholders or officers of an organization that has a relationship with us) and are independent within the meaning of the rules and regulations of the NYSE Amex and NI 58-101 director independence standards. Mr. Porter, as our President and Chief Executive Officer, is not considered to be independent. Further, the Board has determined that each of the members of the Audit Committee, the Remuneration Committee, the Nomination Committee, the Corporate Governance Committee and the Reserves Committee has no material relationship with us (either directly or as a partner, shareholder or officer of an organization that has a relationship with us) and is independent within the meaning of the rules and regulations of the NYSE Amex and the NI 58-101 director independence standards.

Board and Committee Meetings

The Board meets a minimum of four times per year. In addition, the Board meets at such other times as may be required if it is not possible to deal with our business at a regularly scheduled quarterly meeting.

The Board facilitates its independent supervision over management in a number of ways, including by holding regular meetings at which members of management and non-independent directors are not in attendance and by retaining independent consultants where it deems necessary.

For the year ended December 31, 2009, each member of the Board and each director that was a member of a committee attended at least 85% of all meetings held by the Board and each committee of which he was a member at the time of the meeting. The following chart discloses the number of Board and Committee meetings held during 2009 and the attendance of each director.

Table of Contents

Board Composition and Leadership Structure

Mr. Rooney serves as our Chairman of the Board, and Mr. Porter serves as our President and Chief Executive Officer and also is a director. We separated the positions of Chairman of the Board and Chief Executive Officer in January 2010, and we named Mr. Rooney as Chairman. In connection with our entry into an agreement with Palo Alto Investors, LLC relating to certain corporate governance matters (as discussed in more detail under the heading “Certain Relationships and Related Transactions” on page 32 of this Proxy Statement), our Board determined that the separation of these roles would maximize management’s efficiency and further our ongoing efforts to strengthen corporate governance and assure shareholder representation and the independent, objective and effective oversight of management. Separating these positions allows our Chief Executive Officer to focus on our day-to-day business, while allowing the Chairman to lead the Board in its fundamental role of providing guidance to and oversight of management. On January 11, 2010, our Board approved amendments to our Bylaws and corporate governance guidelines have been amended to require this separation, as the Board believes that having separate positions for the Chairman of the Board and for the President and Chief Executive Officer is the appropriate leadership structure for us at this time. Our Board, however, periodically reviews its leadership structure and may make changes in the future as it deems appropriate and in the best interests of the Company and our shareholders. If our shareholders approve the related proposal to amend the Bylaws included in this Proxy Statement, the amendment will become effective when it is filed with the Alberta Registrar of Corporations.

Orientation and Continuing Education

When new directors are appointed, they receive orientation, commensurate with their previous experience, on our properties, business, operations and industry and on the responsibilities of directors. Board meetings may also include presentations by our management and employees to give the directors additional insight into our business. New directors are provided with access to our publicly filed documents, technical reports and internal financial information and given copies of all the minutes of Board and Committee meetings and corporate governance materials. Directors are encouraged to ask questions and communicate with management, auditors and technical consultants to keep themselves current with industry trends and developments and changes in the legislation.

Nomination of Directors

The Board has delegated the responsibility of identifying new, director candidates to the Nomination Committee. The process and responsibility of the Nomination Committee is set forth on page 13 under the heading “Nomination Committee”.

Compensation

The Board has delegated the responsibility of determining compensation strategies and recommending the forms and amounts of compensation for directors, officers, consultants and employees to the Remuneration Committee. Please refer to the disclosure on page 12 under the heading “Remuneration Committee”.

Position Descriptions

The Board has developed written position descriptions of responsibilities for each of the Committees, which inter alia, provide guidance on providing effective Board and Committee leadership; overseeing all aspects of its direction and administration in fulfilling the respective terms of reference for the Board and the Committee; and overseeing the structure, composition, membership and activities delegated to the Board and Committees.

The roles and responsibilities of the Chief Executive Officer are established each year through discussion and recommendation by and among the Chief Executive Officer, the Remuneration Committee and the Board. The roles and responsibilities of the Chief Executive Officer are reviewed, discussed and further defined on an ongoing basis through meetings of the Board and the Committees of the Board.

Remuneration Committee

The compensation committee of the Board, which we refer to as the Remuneration Committee, currently is comprised of Messrs. Penner (Chairman), Coley, Rooney and Selser. None of our executive officers serves as a member of a board of directors or compensation committee (or committee performing similar functions) of any other entity, one or more of whose executive officers serve on our Board or Remuneration Committee.

The aim of the Remuneration Committee is to award and compensate our officers and employees in a manner which provides incentives for the enhancement of shareholder value, for the successful implementation of our business plan and for continuous improvement in corporate and personal performance. The compensation program is based on a pay-for-performance philosophy and consists of three components: base salary, annual incentive (bonus) paid in cash and long-term equity based incentives.

The Remuneration Committee reviews and recommends the compensation philosophy and guidelines for us which include reviewing the compensation philosophy and guidelines for employees, including recommendation to the Board for its consideration and approval related to annual salary, incentive policies and programs, material new benefit programs and material changes to existing benefit programs.

The Remuneration Committee reviews on an annual basis the cash compensation, performance and overall compensation package for each executive officer. It then submits to the Board recommendations with respect to the base salary, bonus and participation in long-term incentive compensation arrangements for each executive officer. In conducting its review, the Remuneration Committee was satisfied that all recommendations complied with the Remuneration Committee’s philosophy and guidelines. In 2008, the Remuneration Committee, at the request of the Board, retained an independent consulting firm to prepare a summary regarding current executive compensation environment practices in today’s market. In determining 2009 annual incentive cash awards, the Remuneration Committee used compensation data provided by Equilar, Inc. (“Equilar”), a company that monitors executive and board compensation, equity grants and award policies and corporate compensation practices. For more information on the role of the Remuneration Committee and the use independent consulting firms and market data, see “Executive Compensation” below.

Nomination Committee

The Nomination Committee currently is comprised of Messrs. Selser (Chairman), Coley, Penner and Rooney. The role of the Nomination Committee is to assist the Board in ensuring that the Board is comprised of individuals who are best able to discharge the responsibilities of directors, having an understanding of our industry, stage of growth, the law and the highest standards of governance. The tasks and responsibilities of the Nomination Committee are defined in its Terms of Reference, which was approved by the Board. The Nomination Committee did not meet formally in 2009. The Board, as a whole, did discuss on several occasions and ultimately nominated John R. Rooney to stand for election as a director at the 2009 annual meeting of shareholders. Mr. Rooney was chosen as a director nominee because he brought valuable perspective and industry-specific business knowledge and managerial experience to the Board.

The Board currently does not have a policy relating to consideration of director nominees by our shareholders. The Board may consider such a policy in the future. At present, the Board believes that the Nomination Committee is in the best position to identify and evaluate director candidates. New candidates are identified by the Nomination Committee, whose responsibility is to develop, annually update and recommend to the Board for approval, a long-term plan for the composition of the Board that takes into consideration the following: (a) the independence of each director; (b) the competencies and skills the Board, as a whole, should possess; (c) the current strengths, skills and experience represented by each director, as well as each director’s personality and other qualities as they affect dynamics of the Board; and (d) our strategic direction. Although we

13

do not have a policy regarding the consideration of diversity, in assessing a director nominee, the Board considers the individual’s background, experience and competencies that the Board desires to have represented among its members. From time to time, the Nomination Committee has used a third party to assist it in identifying and evaluating potential director candidates. Most recently in 2009, the Nomination Committee engaged Preng & Associates, an executive search firm, to identify potential director nominees with strong technical and operational backgrounds.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

This Compensation Discussion and Analysis provides information regarding the compensation paid to J. Russell Porter, our President and Chief Executive Officer (“CEO”), and to Michael A. Gerlich, our Chief Financial Officer (“CFO”). These individuals are referred to as “Named Executive Officers”. Messrs. Porter and Gerlich are our only Named Executive Officers.

Compensation Philosophy and Objectives

Our executive compensation program is designed to provide compensation at a level necessary to retain talented and experienced executives and to motivate them to achieve both short-term and long-term corporate goals that enhance shareholder value. Consistent with this philosophy, following are the key objectives of our compensation programs.

Attract, Motivate and Retain Key Employees. Our executive compensation program is shaped by the competitive market for management talent in the independent natural gas and oil exploration and production industry. We believe our executive compensation should be comparable to that of the companies with which we compete for talent. Our goal is to provide compensation and benefits at levels that attract, motivate and retain superior executive talent for the long-term.

Shareholder Interest Alignment. One of the objectives of our executive compensation program is to ensure that an appropriate relationship exists between executive pay, our financial performance and the creation of shareholder value. We believe that linking executive compensation to corporate performance results in a better alignment of compensation with corporate goals and shareholder interests. Our compensation program aligns pay to performance by making a substantial portion of total executive compensation variable, or “at-risk”, through an annual bonus program based on our performance goals and the granting of long-term incentive equity awards, which have included restricted common shares and stock options. As performance goals are met, not met or exceeded, executives are rewarded commensurately.

Determination of Executive Compensation

Role of the Remuneration Committee. Executive compensation is the responsibility of the Remuneration Committee (the “Committee”). The Committee operates under a written charter, or “Terms of Reference”, adopted by the Board. Randolph C. Coley, Robert D. Penner, John R. Rooney and John M. Selser are members of the Board and the current members of the Committee. Mr. Penner is the current Committee Chairman. Each member of the Committee qualifies as an independent director under the NYSE Amex LLC listing standards and under the Exchange Act. A copy of the Committee’s Terms of Reference is available to shareholders on our website at www.gastar.com.

The role of the Committee is to award and compensate our officers and employees in a manner that provides incentives for the enhancement of shareholder value, for the successful implementation of our business plan and for continuous improvement in corporate and personal performance. The compensation program is based on a pay-for-performance philosophy and consists of three components: base salary, annual incentive bonus and long-term equity-based incentive compensation.

Annually, the Committee reviews and recommends the compensation philosophy for executive management and makes a recommendation to the Board for its consideration and approval.

During 2009, the Committee reviewed the cash compensation, performance and overall compensation package for each Named Executive Officer. It then submitted to the Board recommendations with respect to the

15

Table of Contents

salary, bonus and participation in equity-based compensation arrangements for each Named Executive Officer. In conducting, the Committee was satisfied that all recommendations complied with the Committee’s philosophy and guidelines.

Interaction between the Remuneration Committee and Management. Our CEO plays an important role in the executive compensation process and is closely involved in assessing the performance of our other Named Executive Officer and making recommendations to the Committee regarding base salary, bonus targets, performance goals established for the annual incentive plan, and weighting and equity compensation for this executive officer. His recommendations are based on an assessment of the Named Executive Officer’s responsibilities and performance, our performance and the compensation that companies in our peer group pay their executives in comparable positions. Our CFO also plays an important role in our executive compensation process. He makes recommendations to the Committee regarding the structure of the annual cash bonus awards program and the target size of such awards. These recommendations are drawn from his previous work experience, informal discussions with CFOs and review of other companies publicly filed information of other similarly-sized natural gas and oil companies regarding their bonus programs.

Role of Consultant and Market Analysis. For 2009, the Committee utilized 2008 data previously supplied by Longnecker & Associates (“L&A”). L&A is an independent, Texas-based consulting firm that is experienced in executive compensation and has access to national compensation surveys. For the purposes of its report, L&A’s engagement objectives included:

Companies reviewed by L&A included:

Abraxas Petroleum Corporation

Approach Resources, Inc.

Bankers Petroleum

Brigham Exploration Company

Canadian Superior Energy, Inc.

Edge Petroleum Corporation

Falcon Oil & Gas Ltd.

Gasco Energy, Inc.

GeoMet, Inc.

TXCO Resources, Inc.

Warren Resources, Inc.

L&A also provided us with market compensation data from published survey sources utilizing companies that operate in the natural gas and oil industries. Specific surveys included:

16

Table of Contents

In late 2009, the Committee also used market analysis data obtained from Equilar. Equilar allowed the Committee access to its competitive data for a peer group of companies in the natural gas and oil industries with market capitalization and revenues similar to our own. For 2009 annual incentive cash awards, which were paid in 2010, Equilar developed a grouping of approximately 180 similar sized natural gas and oil companies and developed statistics with respect to the groups CEO and CFO base salary, annual incentive bonus and long-term equity-based incentive compensation. This data was then used to develop a smaller company list based on market capitalization and revenues. These statistics were used to judge reasonableness of the annual incentive cash compensation received by our CEO and CFO for 2009. Companies included in this smaller company list were:

Callon Petroleum Co.

GMX Resources Inc.

Harvest Natural Resources Inc.

NGAS Resources, Inc.

Toreador Resources Corporation

Warren Resources Inc.

Based upon comparative pay information of our peer group and the published survey data referred to above, the Committee determined that the Named Executive Officers’ (a) 2009 base salaries were slightly above the market 75^th percentile, (b) 2009 total cash compensation (base salary, plus the annual cash incentive award), excluding one-time bonus awards related to the sale of our assets in Australia and retention, were below the market 50^th percentile, (c) 2009 long-term equity awards were below the market 75^th percentile, and (d) 2009 total direct compensation (total cash compensation, plus equity incentive awards) was below the market 75^th percentile. Based upon these findings, the Committee believes that the individual pay components and total direct compensation levels of the Named Executive Officers in 2009 was fair, reasonable and aligned with competitive pay practices of our peer group and the published survey data.

Though we review information regarding the compensation practices of our peer group of companies and the survey data just discussed, individual compensation decisions for our Named Executive Officers are subject to upward or downward adjustment, based on the recommendations of our CEO and a number of factors related to both corporate and individual performance. We use the data regarding the pay practices of companies in our peer group as a reference point and as a guide to competitiveness and reasonableness, but we do not adhere to rigid targets based upon the compensation components of employees at companies within that group. Our objective is to maintain total direct compensation, consisting of base salary, performance-based cash compensation and equity awards, in proximity to a median range of our peer group. However, the Committee has the discretion to adjust an award upward to account for individual achievement in the last fiscal year, the requirements of a particular position, and market competitiveness for a particular individual’s skills and services, among other factors.

Compensation for our Named Executive Officers and Rationale

Base Salary. Base salary represents the fixed element of the Named Executive Officers’ cash compensation. The base salary reflects results of individual negotiations, economic consideration for each individual’s level of responsibility, expertise, skills, knowledge, experience and performance and reasonable comparability of similar executive base salaries for executives employed by our peer group companies. Each of our Named Executive Officer’s initial annual salary was set in his respective employment agreement but may be adjusted upward or downward at the discretion of the Committee on the anniversary date of each officer’s employment.

Mr. Porter’s base salary was originally set at $450,000 in his employment agreement dated February 24, 2005. The Committee increased Mr. Porters’ base salary to $500,000, effective in September 2009, in recognition of his continued high level of performance and due to us no longer being responsible for Mr. Porter’s Houston living accommodations or travel cost to his previous residence in Miami, Florida. Mr. Gerlich’s base salary originally was set at $275,000 in his employment agreement, dated May 17, 2005. The Committee increased

17

Table of Contents

Mr. Gerlich’s base salary to $300,000, effective as of April 1, 2008, in recognition of his continued high level of performance. Mr. Gerlich’s base salary was not adjusted in 2009 and continues at $300,000. Each of Messrs. Porter’s and Gerlich’s 2009 base salaries slightly exceeded the 75^th percentile of peer group companies based on the Equilar information. The Committee believes that the increased salary levels are appropriate considering the multiple roles that both executives perform their positions.

Annual Cash Incentive Awards. Our annual cash incentive awards reflect our philosophy to reward performance. These awards provide our Named Executive Officers with an opportunity to earn an annual cash bonus based on pre-established operational and financial performance targets and an evaluation of individual performance. At the beginning of 2009, the Committee approved a $900,000 total target cash bonus pool, which was based on the sum of all our employee’s “target bonus” opportunity expressed as a percentage of the employee’s base salary. For 2008 and 2009, the targeted bonus percentages of our CEO and CFO were 50% and 35%, respectively. When combined with base salaries, these target amounts approximated the 50^th percentile range of total cash compensation (base salary plus annual incentive awards) for similar executives with other peer group companies. The bonus pool is accrued throughout the year, and bonuses are paid out early in the following year. The bonus pool is capped at the lesser of twice the target cash bonus pool total or 10% of earnings before interest, taxes and depreciation and amortization.

At the beginning of the year and as part of our budgeting process, specific operational and financial target criteria are established by the Committee. In developing the appropriate target criteria and their respective weightings, the Committee analyzes the relative importance of each of the target criteria to our business strategy for the upcoming year. Each criterion is given a certain weighting, with a majority of the 2009 weighting allocated to operational factors. During the year, operational and financial performance is measured against the criteria. Judgments that the criteria are being met or not being met may lead to an increase in the pool and an adjustment in the bonus accrual. Criteria and weightings used in 2009 were as follows:

If threshold targets are not met with respect to a criterion, then the portion of the bonus allocable to that criterion is not paid. 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. In 2009, based on a weighted average of actual results compared to targets, the overall bonus pool target was adjusted to 44% of the original bonus target, or from $900,000 to 400,000.

Mr. Porter’s 2009 annual target cash bonus was 50% of his annual base salary. Based on an achievement of 44% of target goals, Mr. Porter was entitled to receive 44% of his 50% target opportunity, or a total of approximately 22% of his base salary.

Mr. Gerlich’s 2009 annual target cash bonus was 35% of his annual base salary. Based on our achievement of only 44% of our target goals, Mr. Gerlich was entitled to receive 44% of his 35% target opportunity, or a total of 15% of his base salary.

The Committee elected to adjust the amount of the payout for Messrs. Porter and Gerlich from 22% to 27% and Mr. Gerlich’s from 15% to 20% of their base salaries, which resulted in actual bonuses of $135,000 and

18

Table of Contents

$60,000, respectively. The Committee believed the adjustments from actual target bonus percentages were warranted due to the successful efforts of Mr. Porter’s development of our assets in East Texas and Appalachia Marcellus Shale. Mr. Gerlich’s upward adjustment was due to his continuing efforts regarding the closing of the sale of our Australian assets. These bonuses we paid in cash in early April 2010.

Other Cash Bonus Award. In August 2009, Messrs. Porter and Gerlich received one time cash bonuses of $1,000,000 and $100,000, respectively. The Committee granted these one-time special bonuses as a result of the successful sale of our Australian assets and related retirement of our long-term debt. The bonus grants were based on a study and recommendation prepared by L&A and was consistent to bonuses earned at other companies related to such highly profitable asset sales.

An additional cash bonus was paid to Messrs. Porter and Gerlich in 2009 of $250,000 and $97,000, respectively, as a retention bonus for continuing their employment with us during 2008, which was a period of significant operational and financial instability for us and, in particular, the uncertainty surrounding the GeoStar litigation. These one time cash bonuses were earned and paid in February 2009.

Long Term Stock-based Compensation. We believe that stock-based compensation is the most effective means of linking compensation provided to our Named Executive Officers with long-term operational success and increases in shareholder value. The Board has discretionary authority to determine granting and vesting periods of stock option and restricted common share grants. We use these stock-based compensation as a long-term vehicle for compensation because we believe:

Prior to the adopting of the 2006 Plan, the only vehicle that was available to us for long-term equity incentives was grants of stock options. After the adoption of the 2006 Plan, grants of restricted common shares became available as incentive vehicle. During 2007 and 2008, grants of restricted common shares to employees were used as long-term compensation to balance the types of equity incentives that employees had received to date. 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 alone. During 2009, the Committee used a combination of restricted common share grants and stock option grants as equity incentives. Typically, 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 Committee adheres to our policy of only granting stock-based compensation grants during open trading windows. The 2009 grants of restricted common shares vest in one-quarter increments on the first, second, third and fourth anniversaries of the grant. The 2009 grants of stock options have a life of 10 years and vest in one-quarter increments on the first, second, third and fourth anniversaries of the grant.

In 2009, Messrs. Porter and Gerlich received a restricted common share grants of 180,000 shares and 110,000 shares, respectively, and stock options grants to purchase 30,000 common shares and 20,000 common shares, respectively. These fair values of these grants calculated to be 150% and 143% of Messrs. Porter’s and Gerlich’s base salary, respectively. The goal of the Committee was to move more of the officer’s total executive compensation to variable, or “at-risk” and thus better align the interest of the officer with the shareholders by providing the Named Executive Officers a greater stake in our long-term performance. Historically, Mr. Porter’s and Mr. Gerlich’s long term stock-based compensation awards have been placed materially below the 50^th percentile of our peer group companies’ long term stock-based compensation, which target stock-based compensation to base pay percentages at 180% and 160%, respectively, for similar executives.

All Other Compensation. The Named Executive Officers are eligible to participate on a non-discriminatory basis in the same comprehensive benefits as are offered to all full-time employees. These benefits are provided so

19

Table of Contents

as to assure that we are able to maintain a competitive position in terms of attracting and retaining executive officers and other employees. During 2009, we paid or reimbursed Mr. Porter a total of $24,492 for Houston living accommodations and air travel to his place of residence in Miami, Florida. See Note 3 to “Summary Compensation Table” for details of payment of perquisites to Mr. Porter in 2009. Messrs. Gerlich received no payments in the form of other compensation. The Committee reviews all perquisites and personal benefits available to the Named Executive Officers at least annually. 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. Mr. Porter received no such payments or reimbursements during 2009.

Tax Deductions for Compensation

In conducting our executive compensation programs, the Committee considers the effects of Section 162(m) of the Internal Revenue Code (“Section 162(m)”), which denies publicly held companies a tax deduction for annual compensation in excess of $1.0 million paid to their chief executive officer or any of their four other most highly compensated corporate officers, other than the chief financial officer, who are employed on the last day of a given year, unless their compensation is based on performance criteria that are established by a compensation committee which is made up of outside directors and approved, as to their material terms, by our shareholders. While the Committee generally considers structuring and administering executive compensation plans and arrangements so that they will not be subject to the deduction limit under Section 162(m), the Committee may in the future approve payments that cannot be deducted in order to maintain flexibility in structuring appropriate compensation programs it feels to be appropriate.

Post Termination or Compensation and Benefits

On March 23, 2007, our Board approved a change of control severance plan, as amended February 15, 2008 (the “Severance Plan”), covering all employees, including the Named Executive Officers. The purpose of the severance plan is to promote stability and continuity of management and employees in the event a change of control transaction should occur (as defined below). Pursuant to the terms of our Severance Plan, our Named Executive Officers are entitled to receive certain post-termination compensation and benefits upon the occurrence of certain events. In order for the Named Executive Officers to receive payments under the Severance Plan, the Named Executive Officers would have to be terminated within two years of a change of control. See “Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table” and “Potential Payments upon Termination or Change of Control” below.

Hedging Prohibitions

Our insider trading policy prohibits our Named Executive Officers from engaging in any speculative transactions involving our common shares including buying or selling puts or calls, short sales or purchases of securities on margin or otherwise hedging the risk of ownership of our stock. Any such activity would require the approval and authorization of either the CEO or the Chairman of the Audit Committee (in the case of a transaction involving our CEO).

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:

2006 Plan. At the annual meeting of shareholders held June 4, 2009, we shareholders approved amendments to our 2006 Long-Term Stock Incentive Plan that, effective as of April 1, 2009, merged our Stock Option Plan with and into the 2006 Long-Term Stock Incentive Plan so that all outstanding equity awards and all future equity awards to be made to employees, officers and directors would be under one plan – the “2006 Plan”.

Additionally, the approved amendments to the 2006 Plan (a) provide that the Remuneration Committee, in its discretion, may provide in an award agreement that an individual who is granted an award under the 2006 Plan (a “participant”) may elect to have common shares withheld from (or “netted against”) the total number of common shares otherwise issuable to such participant pursuant to his award in order to pay the exercise or purchase price of such award and/or to satisfy all employer tax withholding obligations with respect to the participant’s award under the 2006 Plan, (b) clarify that common shares issuable under the 2006 Plan and forfeited back to the 2006 Plan will be deemed not to have been issued under the 2006 Plan and will again be available for the grant of an award under the 2006 Plan, (c) provide that common shares withheld from (or “netted against”) an award granted under the 2006 Plan for payment of (1) the exercise or purchase price of an award and (2) all applicable employer tax withholding obligations associated with an award will be deemed not to have been issued under the 2006 Plan and will again be available for the grant of an award under the 2006 Plan, (d) provide that the maximum number of common shares that may be subject to stock options, bonus stock awards, and stock appreciation rights granted to any one individual during any calendar year may not exceed 200,000 common shares (subject to adjustment pursuant to Section 11(a) of the 2006 Plan), and (e) provide that the definition of “performance criteria” in the 2006 Plan include a criteria relating to the growth of our proved natural gas and oil reserves.

Our 2006 Plan authorizes our Board to issue stock options, stock appreciation rights, bonus stock awards and any other type of award, which are consistent with the 2006 Plan’s purposes to our directors, officers and employees and our subsidiaries covering a maximum of 6.0 million common shares. The contractual lives and vesting periods for grants are determined by the Board at the time a grant is awarded. Recent stock option grants have an expiration of ten years. Stock options granted prior to October 2005 have an expiration of five years. The vesting schedule for stock option grants has varied from two years to four years but generally has been over a four-year period vesting at 25% per year beginning on the first anniversary date of the grant. Stock options granted pursuant to the 2006 Plan have exercise prices determined by the Board, but an 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 our common shares are listed. The vesting period for recent restricted common stock grants have typically been over four years, with one-quarter vesting on the first, second, third and fourth anniversaries of the date of grant.

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 or (3) a sale or other disposition of all or substantially all of our assets. The Severance Plan does not change the specific, non-change of control severance payments in place under the existing employment 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 Severance Plan does not allow for any duplication of severance benefits.

For the Named Executive Officers, the Severance Plan provides that if a Named Executive Officer’s employment is terminated within two years following a change of control for any reason other than (i) death, (ii) disability, (iii) by us for “cause” or (iv) by the Named Executive Officer for other than a “good reason,” the Named Executive Officer will receive a lump-sum payment equal to a multiple that is equal to the applicable severance period, as set forth in the 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 Severance Plan:

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 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 CEO, and Michael A. Gerlich, our CFO, effective February 24, 2005, and May 17, 2005, respectively, each amended July 25, 2008. 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.

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 our operations and business, but also his contribution as President and CEO.

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 CFO. Such bonuses may take the form of cash compensation, the award of common shares or stock options, royalty rights or otherwise.

Salary and Cash Bonus in Proportion to Total Compensation

Option Exercises and Stock Vested for 2009

During the year ended December 31, 2009, our Named Executive Officers exercised no stock options. The following restricted common shares vested to the benefit of our Named Executive Officers during 2009:

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 for Messrs. Porter and Gerlich below assume that such termination was effective as of December 31, 2009, and thus include amounts earned through such date and are estimates of the amounts that 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 Named Executive Officer is terminated.

26

Table of Contents

Per Mr. Gerlich’s employment agreement, if he is involuntarily terminated for any reason other than for Reasonable Cause (as defined below), he will be entitled to a lump sum severance payment equal to the product of 2.5 and the sum of (1) his highest annual base salary in effect at any time during the one year period preceding his termination (at December 31, 2009, this amount was $300,000) and (2) his target bonus amount of 35% of his base salary ($105,000). If Mr. Gerlich is considered a “specified employee” under Section 409A of the Code at the time of his termination, this payment will be delayed for a period of six months if necessary to avoid the additional excise tax under Section 409A of the Code. If Mr. Gerlich timely elects COBRA continuation coverage, he and his family will be entitled to continuation of health insurance at our expense, the “COBRA Continuation Period”. As of December 31, 2009, the cost for health and medical coverage for Mr. Gerlich and his family was $1,619 per month for Mr. Gerlich’s family. If Mr. Gerlich dies during the COBRA Continuation Period, his family will be entitled to continuation of health insurance at our expense, subject to the limitations imposed by law and our insurance plan. At December 31, 2009, the maximum cost over the 18-month period would be $20,538 at $1,141 per month. In addition, Mr. Gerlich will receive a lump-sum cash payment of his unused vacation time of up to 10 days per each year employed, up to a maximum of 15 days. As of December 31, 2009, Mr. Gerlich had 8.6 days of available accrued but unused vacation pay. Per Mr. Gerlich’s stock option agreements, he will have 90 days after termination to exercise all vested options. As of December 31, 2009, Mr. Gerlich had 37,500 unvested stock options. As of December 31, 2009, the only options that Mr. Gerlich held that were “in-the-money” were unvested stock options, thus there are no payments included for him in this column relating to stock option exercises. Additionally, on December 31, 2009, he had 158,333 unvested restricted common shares, but all such unvested restricted common shares would be canceled upon his termination.

27

Table of Contents

The employment agreements of Messrs. Porter and Gerlich 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 our best interests.

“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.

28

Table of Contents

Under Mr. Gerlich’s employment agreement, a “change of control” occurs 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 Severance Plan generally uses the following terms:

“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 or (3) a sale or other disposition of all or substantially all of our assets, or (4) the Board’s adoption of a plan of dissolution or liquidation for us.

“Involuntary Termination” means any termination of employment that occurs within two years following a Change of Control and which (1) is by us other than for cause (but excluding a termination due to the employee’s failure to accept comparable employment), or (2) is by the employee for Good Reason. An “Involuntary Termination” does not include: (a) a termination of the employee by us for cause, (b) a termination of the employee due to his death or disability, (c) a voluntary resignation by the employee other than for Good Reason, or (d) any termination of the employee by the employer as a result of the employee declining to accept an offer of comparable employment with a successor employer.

“Good Reason” means the occurrence of any of the following events after a Change of Control: (1) relocating the covered employee’s place of employment without his consent to a place that would constitute a material change in his place of employment 2) reducing the covered employee’s annual base salary or (3) 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.

The 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 4999 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 accounting firm.

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 compete with us directly or indirectly.

Mr. Gerlich’s employment agreement provides that, unless specifically pre-approved by the CEO 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.

DIRECTORS’ COMPENSATION FOR 2009

Effective July 1, 2008, non-employee directors received the following fees:

We also grant to our non-employee directors stock options and restricted common shares under our stock-based compensation plan in addition to their specified cash compensation to be paid as directors. These grants are, in part, to compensate our directors for the strict 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 following table shows certain information about non-employee director compensation for the year ended December 31, 2009:

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Palo Alto Investors, LLC

On January 12, 2010, we entered into an agreement with Palo Alto Investors, LLC and certain of its affiliates (collectively, “Palo Alto”) with respect to certain governance matters of the Company. Palo Alto is an investment advisory firm that, as of January 12, 2010, owned or exercised control or direction over 4,674,744 common shares, which at such time represented approximately 9.3% of our outstanding common shares.

Pursuant to the agreement, we agreed that no later than January 15, 2010, the Board would appoint a new independent director to the Board and to the Nomination Committee. We also agreed that the Board would authorize an increase in the size of the Board to six directors, subject to approval by the shareholders at the Annual Meeting, and take all actions necessary to cause one additional new independent director to be recommended by the Nomination Committee to the shareholders for election at the Annual Meeting. We further agreed that no later than January 15, 2010 the Board and our management would cause the positions of Chief Executive Officer and Chairman of the Board to be held by different individuals and to take all actions necessary to amend our Bylaws to prohibit any one person from holding both positions concurrently.

The parties’ rights and obligations under the agreement will terminate upon the earlier to occur of: (i) December 31, 2010; (ii) the date 90 days following the date on which Palo Alto and its affiliates own shares of any class of our capital stock that are then entitled to vote generally in the election of directors that represent, in the aggregate, 5.0% or less of the Company’s then-outstanding common shares, provided that such ownership has remained at or below 5.0% for the entire 90-day period; (iii) the date that the Board publicly announces its intention to solicit a proposal for (a) the merger, consolidation, amalgamation, arrangement, share exchange, business combination, liquidation, dissolution, recapitalization, reorganization or other similar transaction involving the Company, (other than any such transaction where the Company is the surviving person or immediately after such transaction the former shareholders of the Company own a majority of the equity interest of the surviving person), (b) the sale or issuance of more than 50% of the capital stock of the Company or its subsidiaries, (c) the sale of more than 50.0% of the assets or businesses of the Company and its subsidiaries (each a “Sale Proposal”), or (d) publicly approves or recommends to the Company’s shareholders their approval of, or their conveyance of any Voting Securities pursuant to, any Sale Proposal; (iv) the date that the Company has entered into a letter of intent, agreement in principle, definitive agreement, or any similar agreement with any party (other than a customary confidentiality agreement) with respect to a Sale Proposal; or (v) the date that any person or group shall have acquired or announced its intention to acquire, including by commencement of a tender offer or exchange offer, beneficial ownership of more than 50.0% of the Voting Securities.

Pursuant to the agreement, on January 13, 2010, the Board appointed Randolph C. Coley as a director and a member of each of the Audit, Nomination and Corporate Governance Committees of the Board, and he was subsequently appointed to the Remuneration and Reserve Committees. Mr. Coley has been nominated to stand for election at the Annual Meeting, and the Nomination Committee has also named Floyd R. Price as an additional director to stand for election at the Annual Meeting pursuant to the agreement.

Chesapeake Energy Corporation

On November 4, 2005, November 11, 2006 and May 23, 2007, Chesapeake Energy Corporation (“Chesapeake”) acquired 5,430,328, 1,000,000 and 351,439 common shares, respectively, in private placement transactions. Chesapeake has the right, with certain exceptions, to maintain its percentage ownership of us, on a fully diluted basis, by participating in future stock issuances and has the right to have an observer present at meetings of the Board. As of April 14, 2010, Chesapeake owned 6,781,767, or 13.5%, of our outstanding common shares.

Policies Relating to Related Party Transactions

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.

LEGAL PROCEEDINGS

We are a 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 following litigation matter relates to a related party and is summarized below.

Navasota Resources L.P. (“Navasota”) vs. First Source Texas, Inc., First Source Gas L.P. (now Gastar Exploration Texas LP) and Gastar Exploration Ltd. (Cause No. 0-05-451) District Court of Leon County, Texas 12th Judicial District. This lawsuit, dated October 31, 2005, contends that the Company breached Navasota’s preferential right to purchase 33.33% of the Company’s interest in certain natural gas and oil leases located in Leon and Robertson Counties and sold to Chesapeake Energy Corporation pursuant to a transaction closed November 4, 2005. The preferential right claimed is under an operating agreement dated July 7, 2000. The Company contends, among other things, that Navasota neither properly nor timely exercised any referential 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, rendering judgment in favor of Navasota on its claims for breach of contract and specific performance, and remanding the case for further proceedings on Navasota’s other counts, which include claims for suit to quiet title, trespass to try title, tortious interference with contract, conversion, money had and received, and declaratory relief. The Company and Chesapeake filed a motion for rehearing on February 6, 2008, which was denied on March 18, 2008. The Company and Chesapeake filed a joint Petition for Review in the Texas Supreme Court on May 13, 2008. On August 28, 2008, the Texas Supreme Court requested briefing on the merits. On January 9, 2009, the Texas Supreme Court denied the Petition for Review. On January 26, 2009, the Company and Chesapeake jointly filed a motion for rehearing in the Texas Supreme Court on its denial of the Petition for Review. On April 24, 2009, the Texas Supreme Court denied the Petition for Review.

Pursuant to a provision in the November 4, 2005 Purchase and Sale and Exploration Development Agreement with Chesapeake, Chesapeake acknowledged the existence of the Navasota lawsuit and claims and further agreed that if Navasota were to prevail on its claims, that Chesapeake would convey the affected interests it purchased from the Company to Navasota upon receipt of the purchase price and/or other consideration paid by Navasota. Therefore, the Company believes that Navasota’s exercise of its rights of specific performance should impact only Chesapeake’s assigned leasehold interests. However, in December 2008, Chesapeake stated to the Company that if the Texas Supreme Court were not to reverse the decision of the Tenth Court of Appeals, Chesapeake would seek rescission of the 2005 transaction and restitution of consideration paid, indicating that Chesapeake might assert such rescission and restitution as to the November 4, 2005 Purchase and Sale and Exploration Development Agreement; a November 4, 2005 Exploration and Development Agreement; and a November 4, 2005 Common Share Purchase Agreement. In its December 2008 communication, Chesapeake did

33

Table of Contents

not identify particular sums as to which it might seek restitution, but amounts paid to the Company in connection with the 2005 transaction could be asserted to include the $76.0 million paid by Chesapeake for the purchase of 5.5 million common shares as part of the transaction in 2005 and/or other amounts. Chesapeake has amended its Answer to include cross-claims and counterclaims, including a claim for rescission.

On or about June 9, 2009, Navasota filed and served its Fourth Amended Petition, essentially re-pleading its previously-asserted claims against the Company and Chesapeake. Navasota has exercised its rights of specific performance, and Chesapeake assigned leases to Navasota in July 2009.

In addition, while the Navasota Resources litigation 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. The Company intends to vigorously defend all claims asserted in the suit.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Exchange Act requires our officers and directors and persons who own more than 10% of our Common Stock to file reports of ownership and changes in ownership with the SEC. These persons are required by SEC regulations to furnish us with copies of all Section 16(a) reports they file. Based on our review of the copies of such reports, we believe that all such filing requirements were complied with during the fiscal year ended June 30, 2003 except as follows:

At our 2009 annual meeting of shareholders held on June 4, 2009, John R. Rooney was elected a director, which required that a “Form 3” be filed with the SEC no later than June 14, 2009. Mr. Rooney’s Form 3 was filed on June 23, 2009.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

During the year ended December 31, 2009, the Compensation Committee of the Board, which we refer to as the Remuneration Committee, was comprised of three independent directors: Messrs. Penner (Chairman), Rooney and Selser. None of these directors who served on the Remuneration Committee during 2009 is or has ever served as one of our officers or employees. None of our executive officers serves or has served as a director or member of a board of directors or compensation committee (or committee performing similar functions) of any other entity, one or more of whose executive officers serve on our Board or Remuneration Committee.

BOARD ROLE IN OVERSIGHT OF RISK MANAGEMENT

The Board is actively involved in oversight of risks that could affect us. This oversight is conducted in part through committees of the Board. In particular, the Audit Committee is charged with oversight of our risks relating to finance, legal, regulatory and accounting compliance, and is updated at least quarterly on our compliance with internal controls. The Board satisfies its oversight responsibility through full reports by each Committee Chairman regarding the Committee’s considerations and actions, as well as through reports from officers responsible for oversight of our particular risks. In addition, we have internal audit systems in place to review adherence to established policies and procedures.

PARTICULARS OF MATTERS TO BE ACTED UPON AT THE 2010 ANNUAL MEETING

Proposal 1. Fixing the Number of Directors at Six (6)

Our Bylaws require that our shareholders fix the number of directors on the Board for the following year. The Board was fixed by the shareholders at five (5) members at our 2009 annual meeting of shareholders. The Nomination Committee has recommended six (6) for election to the Board at the Annual Meeting. Our Amended and Restated Articles of Incorporation provide that the Board be comprised of a minimum of three (3) and a maximum of fifteen (15) members. Accordingly, a proposal to fix the number of members of the Board at six (6) is being presented to our shareholders for approval at the Annual Meeting.

As discussed in more detail under the heading “Certain Relationships and Related Transactions – Palo Alto Investors, LLC” on page 32 of this Proxy Statement, Mr. Price has been nominated for election and Mr. Coley was named to the Board in January 2010 and has been nominated for re-election pursuant to an agreement dated January 12, 2010 between the Company and Palo Alto Investors, LLC, an investment advisory firm that, as of January 12, 2010, owned or exercised control or direction over approximately 9.3% of our outstanding common shares. Pursuant to the agreement, we were obligated to appoint a new independent director to the Board and to the Nomination Committee by January 15, 2010 and were further obligated to recommend the approval of an increase in the size of the Board to six (6) directors and, in connection therewith, the election of one additional new independent director to be recommended by the Nominating Committee for election at the Annual Meeting.

The affirmative vote of a majority of the votes cast in person or by proxy is required to fix the Board at six (6) members.

THE BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE PROPOSAL TO FIX THE NUMBER OF MEMBERS OF THE BOARD AT SIX.

Proposal 2. Election of the Board

As of the Record Date, the Board consists of five directors and the term of each director currently serving on the Board will expire on the date of the Annual Meeting. Based upon the recommendation of the Nomination Committee, Messrs. Porter, Penner, Rooney, Selser and Coley have been nominated for re-election to the Board at this Annual Meeting. Subject to the shareholders’ approval of Proposal 1, the Nomination Committee has also recommended the nomination of Floyd R. Price as an additional director to stand for election as a director at the Annual Meeting.

If any nominee should become unavailable for election, your proxy may be voted for a substitute nominee selected by the Board, or the Board’s size may be reduced accordingly. The Board is unaware of any circumstances likely to render any nominee unavailable. Once elected, our directors hold office until our next annual meeting of shareholders, until successors are elected and qualified or until their earlier resignation of removal.

As discussed in more detail under the heading “Corporate Governance” on page 7 of this Proxy Statement, the Board considers several qualifications, characteristics and other factors when evaluating individual directors, as well as the composition of the Board as a whole. As part of this process, the Board and its Nominating and Corporate Governance Committees review the particular experiences, qualifications, attributes or skills that caused the Nomination and Corporate Governance Committees and the Board to determine that the person should serve as one of our directors. The biographies of each of the nominees below contain information as of April 14, 2010 regarding the person’s service as a director, business experience, director positions held currently or at any time during the last five years and information regarding involvement in certain legal or administrative proceedings over the past 10 years, if applicable. They also highlight the particular experiences, qualifications, attributes or skills that caused the Nomination and Corporate Governance Committees and the Board to conclude that the person should serve as a director of the Company.

In January 2010, we separated the positions of Chairman of the Board and Chief Executive Officer and our Board approved amendments to our Bylaws to effect and require the same, as set forth below. Accordingly, we are seeking shareholder ratification of an amendment to our Bylaws to prohibit any one person from holding the positions of both Chairman of the Board and Chief Executive Officer concurrently. For more information regarding the reasons for and general effect of the proposed amendment, see “Corporate Governance – Board Composition and Leadership Structure” on page 9 and “Certain Relationships and Related Transactions – Palo Alto Investors, LLC” on page 32.

Form of Amendment. Based on the foregoing discussion, the Board requests that shareholders approve the amendment of Subsection 5 of Section VI of the Bylaws to read as follows:

“5. Chairperson of the Board

If appointed and present at the meeting, the Chairperson of the Board presides at all meetings of Directors, Committees of Directors and, in the absence of the President, at all meetings of Shareholders. The Chairperson of the Board must be a director and must not concurrently hold the office of Chief Executive Officer of the Corporation.”

The affirmative vote of a majority of the votes cast in person or by proxy is required to approve the foregoing amendment to the Bylaws.

THE BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR” AMENDING OUR BYLAWS TO PROHIBIT ANY ONE PERSON FROM HOLDING THE POSITIONS OF BOTH CHAIRMAN OF THE BOARD AND CHIEF EXECUTIVE OFFICER CONCURRENTLY.

Unless otherwise directed, it is management’s intention to vote the proxies in favor of an ordinary resolution to ratify the appointment of the firm of BDO Seidman, LLP as our independent registered public accounting firm.

HOUSEHOLDING OF PROXY MATERIALS

We have adopted a procedure approved by the SEC called “householding”. Under this procedure, shareholders of record who have the same address will receive only one copy of the proxy material unless we have received contrary instructions from one or more of such shareholders. This procedure reduces our printing costs and postage fees. Shareholders at a shared address to which a single copy of the proxy materials was delivered who would like to receive a separate copy of the proxy materials (including with respect to those materials that may be delivered to shareholders in connection with future annual or special meetings of shareholders) should contact us by written notification to our corporate offices at 1331 Lamar Street, Suite 1080, Houston, Texas 77010 or by telephone at 713/739-1800, and upon receipt of such request, we will promptly provide a separate copy of the proxy materials. Shareholders who currently receive multiple copies of the proxy materials at their shared address and would like to request “householding” of their communications should notify us of the same at the contact information set out above.

SHAREHOLDER PROPOSALS AND NOMINATIONS

Any shareholder who wishes to submit a proposal for inclusion in the proxy materials for our annual meetings must comply with the requirements of Rule 14a-8 under the Exchange Act. Under Rule 14a-8, such proposal must be submitted to our Secretary at the address indicated on the cover page of this Proxy Statement, so that the Secretary receives it no later than December 31^st of the year that the annual meeting is held (assuming that it is held in June of that year). However, if the date of the 2011 annual meeting of shareholders is changed by more than 30 days from June 3, 2011, the deadline is a reasonable time prior to our printing of the proxy materials, which deadline will be communicated to the shareholders in our public filings.

ADDITIONAL INFORMATION

Additional information relating to us is and filed with the SEC at www.sec.gov and is available on SEDAR at www.sedar.com. Shareholders may contact us at 1331 Lamar Street, Suite 1080, Houston Texas 77010 to request at no charge copies of our 2009 Form 10-K, which includes our financial statements for the year ended December 31, 2009.
