ELECTION OF DIRECTORS

Pursuant to the Company’s Bylaws, the Board of Directors is divided into three classes, each of which class consists, as nearly as possible, of one-third of the total number of directors constituting the entire Board of Directors. Directors for Class II are to be elected at this Annual Meeting for three-year terms expiring in 2009. Richard W. Cardin, Thomas C. Meredith, Nancy K. Quinn, Stephen R. Springer and Richard Ware II have been nominated to serve as Class II directors. All nominees were recommended for nomination by the non-management members of the Nominating and Corporate Governance Committee of the Board of Directors. We did not pay a fee to any third party to identify, evaluate or assist in identifying or evaluating potential nominees for the Board of Directors. The Nominating and Corporate Governance Committee did not receive any recommendations from a shareholder or a group of shareholders who, individually or in the aggregate, beneficially owned greater than five percent of our common stock for at least one year.

Mr. Cardin, Dr. Meredith, and Mr. Ware were last elected to three-year terms by the shareholders at the 2003 Annual Meeting. Ms. Quinn was elected to a one-year term as a Class II director by the shareholders at the 2005 Annual Meeting, after having been appointed to the Board effective August 16, 2004, while Mr. Springer was appointed to the Board as a Class II director, effective September 1, 2005. The Board is nominating Ms. Quinn, Dr. Meredith and Messrs. Cardin, Springer and Ware to continue serving as Class II directors, whose three-year terms will expire in 2009.

The other directors listed on the following pages will continue to serve in their positions for the remainder of their current terms. The names, ages and biographical summaries of (i) the persons who have been nominated to serve as directors of the Company and (ii) the directors who are continuing in office until the expiration of their terms and the class in which such nominee or other director has been designated, are set forth in the following table. Each of the nominees has consented to be a nominee and to serve as a director if elected, and all votes authorized by the enclosed proxy will be cast FOR all of the nominees. If we receive proxies that are signed but do not specify how to vote, we will vote your shares FOR all of the nominees. If we receive proxies that contain a vote to “withhold authority” for the election of one or more director nominees, such vote will not be counted in determining the number of votes cast for those nominees but will be counted for quorum purposes. In order to be elected as a director, our Bylaws require a nominee to receive the vote of a majority of all outstanding shares of our common stock entitled to vote and represented in person or by proxy at a meeting of shareholders at which a quorum is present.

Certain Business Relationships

Until his retirement from the firm in March 2003, Mr. Gordon was Vice Chairman, Investment Banking, for Merrill Lynch & Co., which firm has provided various types of investment banking services to the Company, including serving as an underwriter on our public debt and equity offerings and providing advice in connection with merger and acquisition transactions. Mr. Ware is the president and a shareholder of Amarillo National Bank, Amarillo, Texas, which bank provides an $18 million short-term line of credit to the Company, serves as a depository bank for the Company and is trustee for the Company’s 1998 Long-Term Incentive Plan. The Company pays fees to Amarillo National Bank, which are normal and customary for these types of services.

Independence of Directors

All non-management members of the Board of Directors, other than Mr. Springer, satisfy the independence requirements of the New York Stock Exchange. Because Mr. Springer’s son-in-law is employed as an auditor with Ernst & Young LLP, the Company’s independent registered public accounting firm, under the corporate governance-related listing standards of the New York Stock Exchange, Mr. Springer may not be considered independent from the Company. Mr. Springer’s son-in-law is not involved in the audit of the Company and is not considered a “covered person” with respect to the Company, as defined under the SEC’s independence-related regulations for auditors. Thus, this relationship has no effect on Ernst & Young LLP’s independence as our auditors. In addition, Mr. Springer does not serve on our Audit Committee. The Board of Directors has also adopted categorical standards of director independence, which are attached as Exhibit A to this Proxy Statement, which standards supplement the independence requirements by the New York Stock Exchange. Directors who meet these standards are considered to be “independent.” Note that for purposes of the standards, the Board has adopted the definition of an “immediate family member”, as set forth by the New York Stock Exchange, which includes parents, siblings and in-laws of the director, as well as anyone else (other than domestic employees) who shares such director’s home. The Board has determined that Messrs. Gordon and Ware, as well as all other current non-management directors other than Mr. Springer, as discussed above, meet these standards and are, therefore, considered to be independent directors because none of their relationships with the Company have been determined to be material.

Presiding Director and Communications with Directors

In accordance with the corporate governance-related listing standards of the New York Stock Exchange, the Company has designated Mr. Vaughan as the presiding director at all meetings of non-management directors during the 2006 fiscal year, which meetings will be held on a regular basis. Shareholders may communicate with Mr. Vaughan, individual non-management directors, or the non-management directors as a group, by writing to Board of Directors, Atmos Energy Corporation, P.O. Box 650205, Dallas, Texas, 75265-0205 or by email at boardofdirectors@atmosenergy.com. The Senior Vice President and General Counsel of the Company, Louis P. Gregory, receives all such communications initially and forwards such communications to Mr. Vaughan or another individual non-management director, if applicable, as he deems appropriate. Shareholders may also contact the only management director of the Company, Mr. Robert W. Best, Chairman, President and Chief Executive Officer, by mail at Atmos Energy Corporation, P.O. Box 650205, Dallas, Texas 75265-0205, by email at robert.best@atmosenergy.com or by telephone at 972-934-9227.

The Board of Directors: Committees, Meetings and Directors’ Fees

Standing Committees.     The Company has certain standing committees, each of which is described below.

The Executive Committee consists of Messrs. Best, Koonce and Vaughan. Mr. Vaughan serves as chairman of the committee. In accordance with the Bylaws of the Company, the Executive Committee has, and may exercise, all of the powers of the Board during the intervals between the Board’s meetings, subject to certain limitations and restrictions as set forth in the Bylaws or as may be established by resolution of the Board of Directors from time to time. In addition, Messrs. Best and Vaughan serve as ex officio members of every other Board Committee. The Executive Committee held no meetings during the 2005 fiscal year.

The Board of Directors has established a separately-designated standing Audit Committee in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934. The Audit Committee consists of Ms. Quinn and Messrs. Bain, Busbee, Cardin and Dr. Meredith. Mr. Busbee serves as chairman of the committee. Each member of the Audit Committee satisfies the independence standards of Section 301 of the Sarbanes-Oxley Act of 2002 and related rules and regulations of the Securities and Exchange Commission, as well as the corporate governance-related listing standards of the New York Stock Exchange. The Board of Directors has designated Messrs. Busbee and Cardin as well as Ms. Quinn, each as an “audit committee financial expert,” as such term is defined by applicable rules and regulations of the Securities and Exchange Commission. The Audit Committee oversees the accounting and financial reporting processes and procedures of the Company; reviews the scope and procedures of the internal audit function; appoints the Company’s independent registered public accounting firm and is responsible for the oversight of its work and the review of the results of its independent audits. The

9

Audit Committee held eight meetings during the last fiscal year. The Audit Committee has adopted a charter, which it follows in conducting its activities. The Committee’s charter is attached hereto as Exhibit B and is also available on the Company’s web site at www.atmosenergy.com under the link entitled “Corporate Governance.”

The Human Resources Committee consists of Messrs. Bain, Busbee, Garland, Gordon, Koonce and Nichol. Mr. Koonce serves as chairman of the committee. Each member of the Committee satisfies the independence requirements of the New York Stock Exchange. This committee reviews and makes recommendations to the Board of Directors regarding compensation for the Chief Executive Officer as well as other officers of the Company. In addition to compensation matters, the committee determines, develops and makes recommendations to the Board regarding benefit packages, special bonus or stock plans, severance agreements and succession planning with respect to the Company’s officers. This committee also administers the Company’s 1998 Long-Term Incentive Plan and Annual Incentive Plan for Management. During the last fiscal year, the Human Resources Committee held three meetings. The Committee has adopted a charter, which it follows in conducting its activities. The Committee’s charter is available on the Company’s web site at www.atmosenergy.com under the link entitled “Corporate Governance.”

The Nominating and Corporate Governance Committee consists of Ms. Quinn, Messrs. Cardin, Gordon, Nichol, Ware and Dr. Meredith. Mr. Nichol serves as chairman of the committee. Each member of the Committee satisfies the independence requirements of the New York Stock Exchange. This committee selects candidates for consideration by the full Board to fill any vacancies on the Board, which may occur from time to time, and oversees all corporate governance matters for the Company. The Committee held four meetings during the last fiscal year. The Committee has adopted a charter, which it follows in conducting its activities. The Committee’s charter is available on the Company’s web site at www.atmosenergy.com under the link entitled “Corporate Governance.”

The Committee also considers sound and meritorious nomination suggestions for directors from shareholders. Nominees for director should possess the level of education, experience, sophistication and expertise required to perform the duties of a member of the board of directors of a public company of the Company’s size and scope. Neither the Committee, the Board of Directors nor the Company itself discriminates in any way against potential nominees on the basis of age, sex, race, religion or other personal characteristics. There are no differences in the manner in which the Committee evaluates nominees for director based on whether or not the nominee is recommended by a shareholder. All letters of recommendation for nomination should be sent to the Corporate Secretary of the Company at the Company’s headquarters and must be received no later than January 23, 2006. Such letters should include, in addition to the name, address and number of shares owned by the nominating shareholder, the nominee’s name and address, a listing of the nominee’s background and

10

qualifications. A signed statement from the nominee should accompany the letter of recommendation indicating that he or she consents to being considered as a nominee and that, if nominated by the Board and elected by the shareholders, he or she will serve as a director.

The Work Session/Annual Meeting Committee consists of Messrs. Bain, Garland, Koonce, Nichol, Springer and Ware. Mr. Bain serves as chairman of the committee. This committee selects the site and plans the meeting and agenda for the special meeting of the Board held each year for the purpose of focusing on long-range planning and corporate strategy issues and selects the site for the Annual Meeting of Shareholders. During the last fiscal year, the Work Session/Annual Meeting Committee held three meetings.

Attendance at Board Meetings.     During the last fiscal year, the Board of Directors of the Company held 13 meetings. During the 2005 fiscal year, each director attended at least 75 percent of the aggregate of (a) all meetings of the Board and (b) all meetings of the committees of the Board on which such director served. In addition, all members of the Board of Directors attended the 2005 Annual Meeting of Shareholders in Dallas, Texas on February 9, 2005. The Company strongly supports and encourages each member of the Board of Directors to attend each of the Company’s annual meetings of shareholders.

Directors’ Fees.     As compensation for serving as a director, each of the non-employee directors receives an annual retainer of $30,000; however, beginning October 1, 2005, each of the non-employee directors will receive an annual retainer of $35,000. Each non-employee director receives a fee of $1,500 per meeting for attendance at each meeting of the Board of Directors or Board committee as well as any other Company-related business meeting (excluding telephone conference meetings). The fee paid to non-employee directors for participation in any telephonic conference meeting is one-half of the regular meeting fee. Committee chairpersons are also paid an additional annual fee of $5,000 for additional work done in connection with their committee duties and responsibilities.

In August 1998, the Board adopted the Company’s Equity Incentive and Deferred Compensation Plan for Non-Employee Directors (the “Plan”), representing an amendment to the Company’s Deferred Compensation Plan for Outside Directors that was originally adopted in May 1990. This amended plan became effective when shareholders of the Company approved such amendment at the 1999 Annual Meeting in February 1999 and replaced the annual pension formerly payable to the Company’s non-employee directors under the Company’s Retirement Plan for Non-Employee Directors. Under the terms of the Plan, each non-employee director is allowed to defer receipt of his annual retainer and meeting fees and to invest his deferred compensation into either a cash account or a stock account. In addition, each non-employee director has received under the Plan an annual grant of share units. Beginning in the 2004 fiscal year, each non-employee director has continued to receive an annual grant of share units under the Company’s 1998 Long-Term Incentive Plan. Such directors have

11

also been allowed to continue to defer receipt of his or her annual retainer and meeting fees and to invest his or her deferred compensation into either a cash account or a stock account under the Company’s 1998 Long-Term Incentive Plan. The specific unit amounts credited to each director are shown in the Security Ownership table on page 3 of this Proxy Statement.

In November 1994, the Board adopted the Outside Directors Stock-for-Fee Plan, which plan was approved by the shareholders of the Company in February 1995. The plan permits non-employee directors to receive all or part of their annual retainer and meeting fees in our common stock rather than in cash or having such retainer and fees deferred under the Company’s Equity Incentive and Deferred Compensation Plan for Non-Employee Directors or 1998 Long-Term Incentive Plan. An election by a director to receive his or her fees in stock does not alter the amount of fees payable but results in the deferral of payment of the stock portion of the fees until after the end of each quarter in which the fees were earned. The number of shares of common stock issued at such time will be equal to (a) the dollar amount of the fees to be paid in stock divided by (b) the fair market value of our common stock on the last day of the applicable quarter. The fair market value is the closing price of a share of our common stock as reported by the New York Stock Exchange. Only whole numbers of shares are issued; fractional shares are paid in cash. All such shares issued to non-employee directors are reflected in the Security Ownership table on page 3 of this Proxy Statement.

Other Compensation for Non-Employee Directors.     The Company provides business travel accident insurance for non-employee directors and their spouses. The policy provides $100,000 coverage to directors and $50,000 coverage to their spouses per accident while traveling on Company business.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 requires the Company’s directors and executive officers and persons who beneficially own more than ten percent of our common stock to file with the Securities and Exchange Commission and the New York Stock Exchange initial reports of ownership and reports of changes in their ownership in our common stock. Directors, executive officers and greater-than-ten-percent beneficial shareholders are required by SEC regulations to furnish the Company with copies of all Section 16(a) forms they file. Based solely on a review of the copies of such reports furnished to the Company, the Company believes that, during the 2005 fiscal year, all of the Company’s directors, executive officers and greater-than-ten-percent beneficial owners were in compliance with the Section 16(a) filing requirements.

Corporate Governance

In accordance with and pursuant to relevant provisions of the Sarbanes-Oxley Act of 2002, related rules and regulations of the Securities and Exchange Commission as well as the corporate governance-related listing

12

standards of the New York Stock Exchange, the Board of Directors of the Company adopted the Company’s Corporate Governance Guidelines and revised the Company’s Code of Conduct, which is applicable to all directors, officers and employees of the Company. In addition, the Board of Directors updated the charters for each of its Audit, Human Resources and Nominating and Corporate Governance Committees. All of the foregoing documents are posted on the Corporate Governance page of the Company’s website at www.atmosenergy.com and are also available in print to any shareholder who requests a printed copy of such documents from the Corporate Secretary at the principal executive offices of the Company.
