The Board of Directors: Committees, Meetings, and Directors' Fees Standing Committees. The Company has certain standing committees, each of which is described below. The members of each committee discussed below served in such capacities during the last fiscal year. The Executive Committee consists of Messrs. Best, Koonce, Quinn 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. The Executive Committee held two meetings during the last fiscal year. The Audit Committee consists of Messrs. Bain, Busbee, Cardin, Lewis, Meredith and Ware. Mr. Busbee serves as chairman of the committee. The Audit Committee reviews the scope and procedures of internal auditing work, the results of independent audits, and the accounting policies of management, and it recommends to the Board the appointment of the Company's outside auditors. The Audit Committee held three meetings during the last fiscal year. 7 The Human Resources Committee consists of Messrs. Bain, Busbee, Garland, Nichol and Quinn. Mr. Quinn serves as chairman of the committee. This committee reviews and makes recommendations to the Board of Directors regarding compensation for 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 Nominating Committee consists of Messrs. Cardin, Koonce, Lewis, Meredith and Nichol. Mr. Nichol serves as chairman of the committee. This committee selects candidates for consideration by the full Board to fill any vacancies on the Board, which may occur from time to time. The Nominating Committee held one meeting during the last fiscal year. The Nominating Committee also considers sound and meritorious nomination suggestions for directors from shareholders. All letters of recommendation for nomination should be sent to the Corporate Secretary of the Company at the Company's headquarters and should include, in addition to the nominee's name and address, a listing of the nominee's background and 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 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 Shareholders Meeting. During the last fiscal year, the Work Session/Annual Meeting Committee held two meetings. Attendance at Board Meetings. During the last fiscal year, the Board of Directors of the Company held ten meetings. During fiscal year 1999, each director attended at least seventy-five 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. Directors' Fees. As compensation for serving as a director, each of the non- employee directors receives an annual retainer of $20,000 and a fee of $1,000 per day for attendance at each Board and committee meeting (excluding telephone conference meetings). The fee paid for participation in a telephonic conference meeting of the Board or a committee is one-half of the regular meeting fee. Committee chairmen are also paid a fee for additional work done in connection with their committee duties. 8 Other Compensation for Non-Employee Directors. In August 1998, the Board adopted the Company's Equity Incentive and Deferred Compensation Plan for Non- Employee Directors, 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 their 1999 Annual Meeting in February 1999. Under the terms of this 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. All directors who are eligible to participate in this plan have elected to receive share units. In addition, under the terms of this plan, the directors receive an annual grant of share units for each year of service on the Board. The specific unit amounts credited to each director are shown in the Security Ownership Table on page 2 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 Common Stock of the Company rather than in cash. 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 the Company's Common Stock on the last day of the applicable quarter. The fair market value is the closing price of a share of Common Stock of the Company as reported by the New York Stock Exchange. Only whole numbers of shares are issued; fractional shares are paid in cash. In addition, 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. Other Arrangements with Mr. Vaughan. Effective October 1, 1994, Mr. Vaughan retired as an officer and employee of the Company and entered into a five-year Consulting Agreement with the Company. Under the agreement, Mr. Vaughan performs such consulting services as the Board may request from time to time. The term of the agreement may be extended for additional one-year periods upon the agreement of the Board and Mr. Vaughan. The term of the agreement was extended by amendment approved by the Board in August 1998 for an additional one-year period, ending September 30, 2000, and again in November 1999 for an additional one-year period, ending September 30, 2001. The agreement provides for future payments to Mr. Vaughan, in consideration for his consulting services, of $130,000 during fiscal year 2000 and fiscal year 2001. During the 1999 fiscal year, Mr. Vaughan received $130,000 in payment for his services under the Consulting Agreement. The payments are made in semi-annual installments payable on October 1 and April 1 of each fiscal year. 9 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 the Company's 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 the Company's 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 last 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.

The following table sets forth the compensation paid by the Company for each of the Company's last three completed fiscal years to Mr. Best and the Company's four most highly compensated executive officers other than Mr. Best.

Since January 1, 1999, the executive officers listed in the Summary Compensation Table have been covered by the Company's new Pension Account Plan, which covers all employees of the Company. Such executive officers had an opening account balance established for them as of January 1, 1999 equal to the then present value of their respective accrued benefits under the Retirement Plan as of December 31, 1998. The present value factor is based on average life expectancy, normal retirement age and a discount rate of seven percent. The Pension Account Plan will credit an allocation to each participant's account at the end of each year according to a formula based on his age, service and total eligible pay up to $160,000 (excluding incentive pay). The Pension Account Plan provides for an additional annual allocation based upon a participant's age as of January 1, 1999 for those participants who were participants in the Retirement Plan. The Pension Account Plan will credit this additional allocation each year through December 31, 2008. In addition, at the end of each year, a participant's account will be credited with interest on the participant's prior year account balance. A special grandfather benefit also applies through December 31, 2008, for participants who were at least age 50 as of January 1, 1999, and who were participants in the Retirement Plan on December 31, 1998. Participants are fully 13 vested in their account balances after five years of eligibility service and may choose to receive their account balances as a lump sum or an annuity. Each of the executive officers listed in the Summary Compensation Table also participates in the Company's Supplemental Executive Benefits Plan (the "Supplemental Plan"), which provides retirement benefits (as well as supplemental disability and death benefits) to all officers and utility business unit presidents of the Company. A participant who has been an officer or utility business unit president for at least two years, has five years of vesting service under the Pension Account Plan or a similar plan, and attained age 55 is entitled to a supplemental pension in an amount that, when added to his or her pension payable under the Pension Account Plan or a similar plan, equals 75% of his compensation, subject to reductions for less than ten years of vesting service and for retirement prior to age 62. The following table illustrates the estimated combined annual benefits payable under the Pension Account Plan and the Supplemental Plan upon retirement at age 62 or later to persons in specified compensation categories and years-of-service classifications as determined in such person's last year of employment.

The Pension Account Plan covers only the regular salary of each of its participants, excluding incentive pay (subject to the maximum covered compensation limit of $160,000 as of January 1, 1997 established by the Internal Revenue Code for qualified plans). The Supplemental Plan covers compensation in an amount equal to the sum of (a) the greater of the participant's annual base salary at the date of termination of employment or the average of the participant's annual base salary for the highest of three calendar years (whether or not consecutive) of employment with the Company; and (b) the greater of the amount of the participant's last award under any of the Company's annual performance bonus or incentive plans or the average of the participant's highest three performance awards under such plan (whether or not consecutive). The amount of current compensation covered by the Supplemental Plan as of the end of the last fiscal year for each of the executive officers listed in the Summary Compensation Table is as follows: Robert W. Best, $1,005,000; Larry J. Dagley, $625,900; J. Charles Goodman, $331,400; Glen A. Blanscet, $246,543; and Wynn D. McGregor, $181,400. Each of such executive officers has the following approximate number of years of credited service under the retirement plans: Mr. Best, 2 years; Mr. Dagley, 2 years; Mr. Goodman, 18 years; Mr. Blanscet, 14 years; and Mr. McGregor, 11 years. Each of the executive officers listed in the Summary Compensation Table has also entered into a Participation Agreement with the Company as required by the Supplemental Plan. The Supplemental Plan provides that the accrued benefits, as calculated pursuant to the plan, of each participant will vest in the event of (a) a termination of the participant's employment by the Company without "cause" (i) following a "change of control" of the Company (as both terms are defined in the plan), (ii) in anticipation of a "change in control" (whether or not a "change in control" ever occurs), or (iii) at the request of a party to a pending transaction that will constitute a "change in control", if and when the transaction is consummated, (b) a termination of the plan, (c) an amendment to the plan resulting in a decrease in the benefits otherwise payable to the participant, (d) a termination of the participant's employment for any reason other than "cause", or (e) a termination of the participant's participation in the plan for any reason other than "cause" prior to the participant's termination of employment. The approval of the United Cities Merger by the shareholders on November 12, 1996 constituted a "change in control" as defined in the Supplemental Plan, and as a result, Messrs. Blanscet, Goodman and McGregor, who were participants in the Supplemental Plan as of November 12, 1996, are each entitled to receive unreduced supplemental pension benefits commencing at age 55. The Participation Agreements set forth the specific rights of the participants to their accrued benefits upon the occurrence of the events described above and constitute enforceable contracts separate from the provisions of the Supplemental Plan. 15 Employment Severance Compensation Agreements and Change-in-Control Arrangements. The Company has entered into severance agreements with each of the executive officers named in the Summary Compensation Table (other than Mr. Blanscet) to provide certain severance benefits for them in the event of the termination of their employment within three years following a "change in control" (as defined in the agreements) of the Company. Under each of the severance agreements and plans described below, a "change in control" of the Company is deemed to occur if, among other things, the shareholders of the Company approve a merger or other similar transaction, whereby the shareholders prior to the transaction will not own at least 60% of the voting power of the Company after the transaction. The severance agreement for each executive officer other than Mr. Goodman provides that if employment is terminated by the Company other than for "cause" (as defined in the agreement), retirement, death, or disability, or by the employee for other than "constructive termination" (as defined in the agreement), the Company will pay such executive officer a lump sum severance payment equal to 2.5 times such executive officer's total compensation, comprised of the annual base salary and "Average Bonus", as such term is defined in the agreement. If the total of such lump sum severance payment plus all other payments, distributions or benefits of any type made to or on behalf of the executive officer results in the imposition of the excise tax imposed by Section 4999 of the Internal Revenue Code, the lump sum severance payment will be increased in an amount required for the executive officer to pay any such excise taxes due the Internal Revenue Service. In addition, such executive officer will be entitled to all rights and benefits, if any, provided under any other plan or agreement between him and the Company. Mr. Goodman's severance agreement provides that if his employment is terminated by the Company other than for "cause" (as defined in the agreement), retirement, death, or disability, or by the employee for "good reason" (as defined in the agreement), the Company will pay him a lump sum severance payment equal to 2.99 times his "base amount" compensation, as defined in Section 280G of the Internal Revenue Code. If the total of such lump sum severance payment plus all other payments made in connection with a change in control pursuant to any other plan, arrangement, or agreement results in the imposition of the excise tax imposed by Section 4999 of the Internal Revenue Code, such lump sum severance payment will be reduced to the extent necessary to make the total of all such payments not be subject to such excise tax unless the total of all such payments as reduced by the amount of such excise tax is greater than the lump sum severance payment described above. In addition, Mr. Goodman will be entitled to all rights and benefits, if any, provided under any other plan or agreement between him and the Company. Each of the executive officers listed in the Summary Compensation Table (other than Mr. Blanscet) also participates in the Company's Restricted Stock Grant Plan and has received, from time to time, awards of stock 16 that are restricted with respect to their transferability. The restrictions lapse pursuant to a schedule established by the Board of Directors at the date of the grant. Notwithstanding any established schedule for the removal of restrictions, however, the restrictions are immediately removed in the event of the participant's death, disability, or retirement at normal retirement age (age 62) or in the event of a "change of control" (as defined in the plan) of the Company. Human Resources Committee Interlocks and Insider Participation. The members of the Human Resources Committee during the last fiscal year were Messrs. Bain, Busbee, Garland, Nichol and Quinn. From August 1998 through August 1999, Mr. Busbee was of counsel to the law firm of Gibson, Dunn & Crutcher in Dallas, Texas, which the Company retains from time to time to perform legal services. There are no interlocking relationships between any executive officer of the Company and any other company. Human Resources Committee Report on Executive Compensation. THE ROLE OF THE COMMITTEE. The Human Resources Committee of the Board of Directors is charged with the responsibility of providing oversight and direction with respect to the compensation programs and employee benefit plans of the Company. All members of the Committee are non-employee directors who serve on the Board of Directors. Specific duties and responsibilities of the Committee include: . The establishment and oversight of the Company's executive compensation policy and strategy. . Development of recommendations to the Board of Directors regarding the pay of Company officers and of the CEO's compensation. . Development of recommendations to the Board of Directors regarding performance targets and criteria underlying the Company's various incentive compensation plans and approval of such targets and criteria with respect to the Company's incentive compensation plans subject to Section 162(m) of the Internal Revenue Code. . Interaction with outside advisors and consultants regarding the Company's current compensation and benefit plans as well as periodic assessments of the competitive marketplace, emerging trends and legislative developments, and best practices employed by other corporations. . Review and determination, for recommendation to the Board of Directors, of the Company's program for providing compensation to non-employee directors. . Assurance that the Company's compensation program for the CEO and other officers is aligned with the Company's overall business strategy and focuses upon the creation of value for the Company's shareholders. 17 This report has been prepared by the Committee immediately following the meeting of the Committee on October 20, 1999, at which time the Committee established incentive targets and performance measures for the 2000 performance year, reviewed salary recommendations for all officers and business unit presidents, and conducted other matters consistent with the Committee's charter. COMPENSATION STRATEGY. The Company's approach to compensation for all employees is based upon the tenets of "total rewards." Total rewards is a comprehensive approach to compensation and benefits which emphasizes the importance of the entire rewards package of the Company: base salary, incentive compensation, employee benefits, training and development opportunities, and the corporate environment. Consistent with the total rewards approach for all employees, the Company's compensation program for executives is founded upon the same underlying tenets of total reward opportunities. The Company's executive compensation strategy is founded upon the following guiding principles: . The Company's executive compensation strategy should be aligned with the overall Company's business strategy of focusing upon growth opportunities in both regulated and nonregulated business sectors, seeking on-going improvements in operating efficiencies and service levels, and preparing for a more competitive environment in a consolidating industry. . Overall pay targets should reflect the Company's intent to pay executive base salaries at the 50th percentile of the competitive market practice with targeted total cash and targeted total direct compensation to be paid at the 75th percentile of competitive market practice if performance targets are reached. . Key executives who are charged with the responsibility for establishing and executing the Company's business strategy should have incentive compensation opportunities that are aligned with the creation of shareholder value. . Stock ownership is an important component for ensuring that executives' interests are aligned with shareholders. . To facilitate stock ownership for executives, the Company should provide stock options and other stock-based incentive vehicles that focus on shareholder value creation. . Incentive compensation opportunities should have significant upside potential with commensurate downside risk. . The Company's compensation strategy should place a greater emphasis upon stock options and related long-term incentive opportunities, with limited emphasis upon special benefits and perquisites. 18 . The incentive compensation plans of the Company, to the extent that it is practical and consistent with the overall corporate business strategy, should comply with Section 162(m) of the Internal Revenue Code so that the Company can take the full tax deduction for executive compensation. SHIFT IN STRATEGY FOR NON-EMPLOYEE DIRECTOR COMPENSATION. The Committee has worked closely with the management consulting firm of Towers Perrin over the past 18 months to ensure that the compensation program for non-employee directors serving on the Board of Directors is competitive and reflective of current best practices in the marketplace. The Company's shareholders last year approved the adoption of the Equity Incentive and Deferred Compensation Plan for Non-Employee Directors. As a result of this action, all current non- employee directors have voluntarily elected to participate in this new plan and to cease their participation in the Company's Retirement Plan for Non- Employee Directors. ASSESSMENT OF COMPETITIVE PRACTICES. The Committee regularly evaluates competitive compensation data provided by management consultants to ensure that the Company's pay policy and practices are aligned with the competitive marketplace. Over the course of the past 12 months, the Committee reviewed on three occasions competitive compensation levels from numerous survey sources and analyses provided by Towers Perrin. These sources of competitive compensation data included: . A review of the total direct compensation of the five highest paid executives for a select peer group of 17 gas utility companies which have annual revenues and market capitalizations comparable to the Company. . Published survey data of the utility industry provided by the Executive Compensation Service. . Published and private survey data of both the utility industry and general industry provided by Towers Perrin. These survey sources provide a comprehensive review of national compensation practices as well as selected companies that compete in specific geographic markets in which the Company participates. The organizations participating in these surveys are different than some of the companies that appear in the attached Performance Graph, which is based upon a published index for local gas distribution companies. Specific job comparisons and access to market data for companies included in the performance graph are not readily available to the Committee. For the most recently completed fiscal year, the Company's executive compensation program was comprised of base salary, annual incentive compensation, and long-term incentive compensation in the form of stock options. The following paragraphs discuss each of these program components. 19 BASE SALARY. All positions in the Company, including executive positions, have been assigned to formal salary grades and ranges. Positions are compared on the basis of job content to similar positions in companies of comparable revenue size and market capitalization to the Company. Salary ranges for all positions are reviewed on an annual basis, and proposed salary ranges are presented to the Committee for its review and consideration each year in October. The midpoint of each salary range is designed to approximate the 50th percentile of base salaries of comparable companies in the marketplace, as defined above. The base salary for an individual executive may be more than or less than the salary range midpoint based upon the individual's performance and his or her level of experience in the position. In determining appropriate salary levels, the Committee also considers current economic conditions and national and industry trends in executive compensation. Each year, the Chief Executive Officer and senior officers of the Company provide the Committee with an oral presentation discussing the performance and contributions of each executive. The Company uses a performance evaluation process that has seven performance ratings and which considers individual goals and areas of accountability. The individual executive's salary increase is based upon his performance rating and the overall salary increase budget and guidelines established by the Company for the year. ANNUAL INCENTIVE COMPENSATION. The Company's corporate officers, business unit presidents, and officers/direct reports to the business unit presidents, participate in the Annual Incentive Plan for Management (the "Incentive Plan"). The Incentive Plan, which has been designed to comply with Section 162(m) of the Internal Revenue Code, considers both financial and operational quantitative measurements of performance at both the corporate and business unit levels. Each participant in the plan has a stated target annual incentive award opportunity stated as a percentage of base salary, with such target opportunities ranging from 10 percent to 60 percent of the participant's respective base salary. Awards pursuant to the Incentive Plan are typically paid in cash. However, subject to the terms of the Plan and the approval of the Committee, the participant may make a voluntary election to convert his award to Company bonus stock, restricted shares or stock options. Such voluntary elections must be made by a participant prior to the beginning of the Performance Period as defined in the Plan. For fiscal year 1999, the Company failed to reach the minimum financial performance hurdle for purposes of funding the Incentive Plan. As such, no incentive awards or bonuses were earned or paid under the provisions of the Incentive Plan to any Company employees for 1999 performance, including the five proxy-named executives. The Company's failure to reach the threshold level of financial performance also resulted in the Company not funding a special incentive plan developed for all employees (eligible participants are those who do not participate in the management plan). 20 LONG-TERM INCENTIVE COMPENSATION. The Company currently grants long-term awards in the form of both time-lapse restricted stock and nonqualified stock options. The Committee believes that restricted shares allow key executives to share fully in the interests of all shareholders by having the executive receive voting rights and dividends applicable to the restricted shares that have been granted. In addition, the Company grants stock options to key executives. All stock options are granted at fair market value on the date of grant and have a term of ten years. Executives will only realize value from their stock options should the share price appreciate above the grant price on the date such option shares were granted. The Committee believes that stock options further parallel the interests of executives with the interests of other shareholders by focusing upon shareholder value. During the 1999 fiscal year, the Company granted nonqualified stock options and restricted stock to a select number of key executives and officers. All of these grants were made in consideration of the Company's performance in fiscal year 1998, a year in which the Company achieved record earnings. In addition, the Company adopted share ownership guidelines for key officers in fiscal year 1999. The guidelines are voluntary and should be achieved by each officer over the course of five years. The Committee strongly advocates executive share ownership as a means by which to better align executive interests with those of all shareholders. The Chief Executive Officer has a guideline to reach a share ownership position of five times his base salary over the course of the five years. Other officer positions have share ownership guidelines ranging from 2.5 to 1.0 times the officer's base salary. COMPENSATION OF THE CHIEF EXECUTIVE OFFICER. The Committee has not changed the base salary of Mr. Robert W. Best, Chairman, President, and Chief Executive Officer of the Company for 2000. In 1999, Mr. Best's base salary was at the level of $555,000. Mr. Best will not earn an annual incentive award under the Annual Incentive Plan for Management for the 1999 fiscal year. The Company's performance did not meet the minimum financial performance hurdle during fiscal year 1999, thereby negating any payouts for participants pursuant to the Incentive Plan. Mr. Best received a grant of 50,000 nonqualified stock options and 50,000 restricted shares during fiscal year 1999, which is consistent with the grants awarded to other Company key executives and with the Company's past practices. Both the nonqualified stock option grant and the restricted stock grant awarded to Mr. Best in fiscal year 1999 were in recognition of Mr. Best's contributions to the achievement of record earnings performance during fiscal year 1998. COMPLIANCE WITH SECTION 162(m). The Board of Directors has elected to fully comply with Section 162(m) of the Internal Revenue Code. The Company's decision to comply means that the Company can maintain the tax deductibility for performance-based compensation paid to the five proxy-named executives. In order to 21 comply with Section 162(m), all actions taken by the Committee with respect to the compensation of the five proxy-named executives will be taken by those members who constitute a "non-employee director" as defined in Section 162(m). One member of the present Human Resources Committee, Dan Busbee, does not meet the Section 162(m) definition due to the professional services provided to the Company by the law firm with which Mr. Busbee was formerly employed until August 1999. Therefore, Mr. Busbee has formally rescued himself from all executive compensation matters discussed by the Human Resources Committee affecting Section 162(m) compliance.
