CORPORATE GOVERNANCE

Board Independence and Composition

The core responsibility of the Board of Directors is to provide objective, independent judgment in its management oversight function and the Board’s composition reflects that principle. The Board is composed of a majority of independent directors. A director’s independence is determined in accordance with the definition set forth in National Association of Securities Dealers (“NASDAQ”) listing standards and other pertinent and applicable legal and regulatory standards. The Board of Directors annually reviews the relationships between directors or members of their immediate families and the Company, in order to make recommendations to the full Board for its determination regarding the independence of each director. As a result of this review, the Board has determined that the following directors are independent directors: Matthias Eckenstein, H. Gifford Fong, Thomas S.T. Gimbel, and Jan K. Smeets.Smeets are independent directors and that Ebersole Gaines Wehrle will qualify as an independent director.

Board Leadership

The Board of Directors, in its discretion, may elect a Chairman of the Board. The Chairman leads the Board and presides at all Board meetings, and is responsible for delivery of information for the Board’s informed decision-making.

Based upon the structure that best serves the interests of the Company, the Board determines whether the role of the Chairman of the Board and the Chief Executive Officer should be held by one individual or should be separated. Currently, the Board believes that the positions of Chairman of the Board and Chief Executive Officer should be held by the same person because this combination has served the Company well in the past and continues to work well today, by providing unified leadership and direction. The Directors have also determined that it is not necessary to appoint a lead independent director at this time.

The Board’s Role in Risk Oversight

The Company’s risk management efforts are the responsibility of the Board of Directors.

All of the members of the Board of Directors attended the Annual Meeting of the Company held in May 20122013 in person except Matthias Eckenstein and Thomas S. T. Gimbel.Gimbel who attended by telephone conference.

Committees of the Board

The Board of Directors has an Executive Committee, an Audit Committee and a Compensation Committee.

Executive Committee

The Executive Committee, composed of Messrs. Drimal, Jr., Hurt, Smeets and Ms. Cummings, is authorized to exercise all the authority of the Board in the business and affairs of the Company, except as limited by applicable law. The Executive Committee met threefour times during 2012,2013, and informally, by telephone conference on a regular basis, usually weekly, during the year.

Audit Committee

The Audit Committee, composed of Messrs. Eckenstein, HurtGimbel and Smeets, met once in 2012.2013. All members of the Audit Committee were independent under NASDAQ listing standards and other pertinent legal and regulatory standards. The Board of Directors has determined that Mr. Smeets meets the qualifications of an “audit committee financial expert” within the meaning of the regulations of the Securities and Exchange Commission and NASDAQ listing standards. The Committee selects and engages independent auditors to audit the books, records and accounts of the Company, determines the scope of such audits, and reviews the financial policies and control procedures of the Company. The report of the Audit Committee is included in this Proxy Statement on page 11.pages 11-12. The Board of Directors and the Audit Committee have adopted a written charter for the Audit Committee, a copy of which wasis attached as AnnexExhibit A to the Company’s 2011this Proxy Statement. The Board of Directors has determined that Mr. Hurt no longer meets the criteria for director independence under NASDAQ listing standards. The Board will select another member of the Committee during 2013.

Compensation Committee

The Compensation Committee, composed of Messrs. Hurt, Gimbel and Smeets, met twiceonce in 2012.2013. All members of the Compensation Committee were independent under NASDAQ listing standards and other pertinent legal and regulatory standards. The charter of the Compensation Committee also requires that members of the Committee also qualify as “outside directors” within the meaning of Section 162(m) of the Internal Revenue and as “non-employee” directors within the meaning of Rule 16b-3 of the Securities Exchange Act of 1934, as amended. The Committee annually reviews and evaluates the Company’s compensation policies and establishes salaries, bonuses and other compensation for the Company’s executive officers and directors. Mr. Drimal and Ms. Cummings participate in discussions with the Compensation Committee and make recommendations to the Committee with respect to the compensation of executive officers and directors. Neither Mr. Drimal nor Ms. Cummings participates in the deliberations or approval of the Committee concerning their respective compensation.

The Board as Nominating Committee

The Company does not have a standing nominating committee. The Board of Directors acts as the nominating committee, with Mr. Drimal and Ms. Cummings abstaining. The majority of the Directors of the Company, Messrs. Eckenstein, Fong, Gimbel and Smeets, who function as a nominating committee, are believed to satisfy applicable regulatory requirements for independence. Those Directors are responsible for collecting and analyzing information with regard to directors’ “independence” as defined by NASDAQ listing standards and other pertinent legal and/or regulatory standards in effect at the time. They are also responsible for making recommendations concerning committee membership and ensuring that committee members satisfy the criteria for membership on a particular committee for independence and have the skills to effectively participate on a particular committee. The Directors who function as the nominating committee are also responsible for identifying and evaluating prospective nominees for vacancies on the Board of Directors. The Board of Directors will consider meritorious director candidates submitted to it by members of the Board and by stockholders of the Company, without regard to race, religion, gender, national origin or disability. The Board does not have a formal policy with regard to considering diversity in its consideration of director nominations. Candidates for election must be willing to devote the time necessary to serve as a director and must possess the level of education, experience, and expertise, both with respect to financial matters and the oil and gas industry in general, required to perform the duties of a member of the board of directors of a public company, and in particular of the Company. The Board of Directors strive to recommend candidates that further its objective of having a board that encompasses a broad range of talents and expertise and reflects a diversity of background, experience and viewpoints. The procedure to be followed by a shareholder to submit a nominee to the Committee is set forth in “Stockholder Proposals and Nominations” in this Proxy Statement.

The Board of Directors believes that this procedure is adequate in the process of selecting persons for elections as Directors of the Company. The sevenAll of the Directors of the Company currently serving as Directors (other than Matthias Eckenstein) were designated as nominees for re-election at the 20132014 Annual Meeting of Stockholders. No other nomineesMr. Eckenstein has chosen not to stand for re-election as a Director at the 2014 Annual Meeting for health reasons. The Board of Directors considered individuals to nominate as director to fill the vacancy left by Mr. Eckenstein’s decision, and recommends Ebersole Gaines Wehrle as nominee for Director. There were considered and no nominations were proposed by any stockholder or group.

EXECUTIVE AND DIRECTOR COMPENSATION

Compensation Overview

The Company has been guided by its Chief Executive Office, Charles E. Drimal, Jr., and Chief Financial Officer, Beverly A. Cummings since 1987. The Board of Directors attributes much of the success of the Company to Mr. Drimal’s and Ms. Cummings’ leadership, skills and dedication to the Company and its shareholders. In order to retain such highly skilled and experienced professionals for its senior management team, the Board of Directors must offer highly competitive compensation packages. At the same time, the Board of Directors is mindful that the primary goal of the Company is to build long-term shareholder value.

There are three elements of the compensation paid to the senior management team, to wit: (i) base salary; (ii) bonus (cash incentive) compensation, and (iii) equity awards. The base salaries that were provided to the senior management team were based upon a number of considerations including each executive officer’s level of responsibility, changes in their responsibilities from year to year, experience, skills and leadership ability. Additionally, the Compensation Committee gave consideration to the executive officer’s ability to be awarded additional compensation in the form of a bonus which compensation was more directly tied to the Company’s performance. After discussing all of those considerations, the Compensation Committee recommended the same percentage increase in each of the executive officer’s salary. The base salary paid to each executive officer in 20122013 is set forth in the “Salary” column of the Summary Compensation Table set forth in this proxy statement.

The cash incentive bonus compensation awarded to each executive officer is intended to correlate to the Company’s performance. The Compensation Committee focused on performance measures such as the increase in oil and gas reserves, cash flow, debt level, growth in the Company’s well servicing subsidiaries and growth in the

Company’s oil and gas operations. The Compensation Committee believes this combination of metric categories isrepresents the important measurementmeasurements necessary for increasing shareholder value and growing the Company. As a result, the Compensation Committee awarded each of the executive officersofficer’s a cash incentive bonus. The cash bonus paid to each executive officer in 20122013 is set forth in the “Bonus” column of the Summary Compensation Table set forth in this proxy statement.

The Company awarded options to purchase shares of the Company’s common stock to the executive officers in May 1989. The objective of the award was to retain high level officers and to motivate them to continue their relationship with the Company and thereby align their interests with the long term interests of its shareholders. The options that were awarded have been fully exercisable by the executive officers since May 1994. The Compensation Committee believes the options awarded to the executive officers represent a significant stake in the Company and determined not to award any more options or other types of equity compensation to the executive officers in 2012.2013.

At the Annual Meeting held in 2013, the shareholders voted to hold an advisory, non-binding vote to approve executive compensation every three years. The next “say on pay” vote will occur at the Company’s Annual Meeting in 2016.

ADVISORY NON-BINDING VOTE ON EXECUTIVE COMPENSATION

(Proposal No. 2 on the Proxy)

The Board of Directors believes that the Company’s compensation programs and policies are centered on a pay for performance culture and are strongly aligned with the long-term interests of shareholders.

The Board of Directors is asking shareholders to vote in an advisory, non-binding manner on the compensation paid to our Principal Executive Officer and Principal Financial Officer (collectively, the “Named Executive Officers”), as disclosed in this Proxy Statement pursuant to Item 402 of Regulation S-K (including the compensation tables and accompanying narrative discussion). Item 402 of Regulation S-K is the SEC regulation that sets forth what companies must include in their proxy statement as to compensation.

This proposal, commonly known as a “Say on Pay” proposal, gives you as a shareholder the opportunity to vote on the Company’s executive pay program. In proposal no. 3, the Board of Directors is seeking your advice

on the frequency of such votes in the future. Pursuant to section 14A of the Securities and Exchange Act of 1934, which is applicable to smaller reporting companies this year, the Board of Directors is requesting shareholders to cast a non-binding advisory vote on the following resolution:

“Resolved, that the compensation paid to the Company’s Named Executive Officers, as disclosed pursuant to Item 402 of Regulation S-K, compensation tables and narrative discussion is hereby APPROVED.”

Since your vote is advisory, it will not be binding upon the Board of Directors. However, the Compensation Committee will take into account the outcome of the vote when considering future executive compensation arrangements.

The Board of Directors recommends a voteFOR this Resolution.

(Proposal No. 2 on the Proxy)

ADVISORY NON-BINDING VOTE ON FREQUENCY OF SAY-ON-PAY VOTES

(Proposal No. 3 on the Proxy)

Pursuant to Section 14A of the Exchange Act, which is applicable to smaller reporting companies this year, our shareholders are being asked to vote, on an advisory basis, on how frequently our shareholders should have a “Say on Pay” vote in the future. Although this frequency vote is advisory and is not binding on the Board of Directors, the Compensation Committee will take into account the outcome of the vote when considering how frequently to hold Say on Pay votes. You may choose from the following alternatives: every year, every two years, every three years or you may abstain. The Directors of the Company will ask you to vote on an advisory basis on the frequency of Say on Pay votes at least once every six years. Shareholders are not voting to approve or disapprove the Board of Director’s recommendation.

The Board of Directors believes and recommends that the Say on Pay vote should be conducted every three years so that shareholders may express their views on the Company’s executive compensation program. The Compensation Committee, which administers the Company’s executive compensation program, values the opinions expressed by shareholders in these votes and will continue to consider the outcome of these votes in making its decisions on executive compensation.

The Board of Directors recommends that you vote to conduct future Say on Pay votes everythree years.

(Proposal No. 3 on the Proxy)
