BOX 98510 - LAS VEGAS, NEVADA 89193-8510 PROXY STATEMENT MARCH 31, 1998 This Proxy Statement is furnished in connection with the solicitation by the Board of Directors of Southwest Gas Corporation (the "Company") of proxies representing the common stock of the Company (the "Common Stock") to be voted at the Annual Meeting of Shareholders of the Company to be held on May 14, 1998, and at any adjournment thereof. This Proxy Statement and accompanying proxy card are being mailed to shareholders on or about March 31, 1998. A form of proxy is enclosed for your use. The Company will acknowledge revocation of any proxy upon request of the record holder made in person or in writing prior to the exercise of the proxy, or upon receipt of a valid proxy bearing a later date. Delivery of said revocation or valid proxy bearing a later date shall be made upon the Corporate Secretary of the Company. If a shareholder executes two or more proxies with respect to the same shares, the proxy bearing the most recent date will be honored if otherwise valid. All shares represented by valid proxies received pursuant to this solicitation will be voted at the Annual Meeting. Where a shareholder specifies by means of the proxy a choice with respect to any matter to be acted upon, his or her shares will be voted in accordance with each specification so made. The entire cost of soliciting proxies will be paid by the Company. In following up the original mail solicitation of proxies, the Company will make arrangements with brokerage houses and other custodians, nominees, and fiduciaries to send proxies and proxy materials to the beneficial owners of Common Stock and will reimburse them for their expenses in so doing. Under an agreement with the Company, Morrow & Co. will assist in obtaining proxies from certain larger and other shareholders at an estimated cost of $4,500 plus certain expenses. The total number of shares of Common Stock outstanding at the close of business on March 18, 1998 (the "Record Date"), the Record Date for the determination of shareholders entitled to notice of and to vote at the Annual Meeting, was 27,521,170. Only holders of Common Stock on the Record Date are entitled to notice of and to vote at the Annual Meeting of Shareholders. The Company will appoint one or three employees to function as inspectors of election in advance of the meeting to tabulate votes, to ascertain whether a quorum is present, and to determine the voting results on all matters presented to shareholders. A majority of all shares of Common Stock entitled to vote, represented in person or by proxy, constitutes a quorum. Abstentions and broker non-votes are each included in the determination of the number of shares present; however, they are not counted for the purpose of determining the election of each nominee for director. Each share of Common Stock is entitled to one vote. Shareholders have cumulative voting rights with respect to the election of directors, if certain conditions are met. Any shareholder otherwise entitled to vote may cumulate his or her votes for a candidate or candidates placed in nomination at the meeting if, prior to the voting, he or she has given notice at the meeting that he or she intends to cumulate his or her votes. A shareholder electing to cumulate his or her votes may cast as many votes as there are directors to be elected, multiplied by the number of shares of Common Stock standing in his or her name on the books of the Company at the close of business on the Record Date. A shareholder may cast all of his or her votes for one candidate or allocate them among two or more candidates in any manner he or she chooses. If any one shareholder has given such notice, all shareholders may cumulate their votes for candidates in nomination. The persons named in the proxies solicited by the Board of Directors, unless otherwise instructed, intend to vote the shares represented by such proxies FOR the selection of Arthur Andersen LLP as independent public accountants and, in the case of the election of directors, 6 equally FOR each of the 11 candidates for director named in this Proxy Statement; HOWEVER, if sufficient numbers of shareholders exercise cumulative voting rights to elect one or more other candidates, the management proxies will (i) determine the number of directors they are entitled to elect, (ii) select such number from among the named candidates, (iii) cumulate their votes, and (iv) cast their votes for each candidate among the number they are entitled to elect. ELECTION OF DIRECTORS (ITEM 1 ON THE PROXY CARD) NAMES AND QUALIFICATIONS OF NOMINEES Each director elected at the Annual Meeting of Shareholders will serve until the next Annual Meeting (normally held on the second Thursday of May) and until his or her successor shall be elected and qualified. Eight of the nominees were elected to their present term of office at the last Annual Meeting of Shareholders on May 8, 1997. Directors Kropid and Wright were elected in July 1997 and Director Biehl was elected in January 1998 to fill retirement vacancies (actual and expected) on the Board.

SELECTION OF INDEPENDENT PUBLIC ACCOUNTANTS (ITEM 2 ON THE PROXY CARD) The Board of Directors has selected Arthur Andersen LLP as independent public accountants for the Company for the year ending December 31, 1998, subject to ratification of the selection by shareholders. Arthur Andersen LLP has served as independent public accountants for the Company since 1957. To the knowledge of the Company, at no time has Arthur Andersen LLP had any direct or indirect financial interest in or any connection with the Company or any of its subsidiaries other than in connection with services rendered to the Company as described below. The affirmative vote of a majority of the shares represented at the Annual Meeting in person or by proxy is necessary to ratify the selection of Arthur Andersen LLP as independent public accountants for the Company. The selection of Arthur Andersen LLP by the Board of Directors was based on the recommendation of the Audit Committee, which is composed wholly of outside directors. The Audit Committee meets periodically with the Company's internal auditors and independent public accountants to review the scope and results of the audit function and the policies relating to auditing procedures. In making its annual recommendation, the Audit Committee reviews both the audit scope and estimated fees for the coming year. If the shareholders do not ratify this appointment, other firms of certified public accountants will be considered by the Board of Directors upon recommendation of the Audit Committee. During 1997, the Company paid Arthur Andersen LLP for (i) the audit of the annual financial statements, (ii) reviews of unaudited quarterly financial information, (iii) assistance and consultation in connection with preparing various Securities and Exchange Commission (the "SEC") filings, (iv) the audit of the annual financial statements of the Company's employee benefit plans, (v) consultation in connection with various tax and accounting matters, and (vi) certain other professional services. The Audit Committee approved the audit and other professional services and considered the costs of all such services and what effect, if any, performance of the other professional services might have on the independence of the accountants. Representatives of Arthur Andersen LLP will be present at the Annual Meeting of Shareholders. They will have the opportunity to make statements, if they are so inclined, and will be available to respond to appropriate questions. GENERAL INFORMATION BOARD OF DIRECTORS The Board of Directors is responsible for the overall affairs of the Company and for establishing broad corporate policies. 8 13 Regular meetings of the Board of Directors are scheduled for the third Tuesdays of January, July, September, and November; the first Tuesday of March; and the second Wednesday of May. An organizational meeting is also held immediately following the Annual Meeting of Shareholders. The Board of Directors held six regular meetings, one special meeting, and one organizational meeting in 1997. Each director attended more than 75 percent of the meetings of the Board of Directors and standing committees on which he or she served during 1997. DIRECTORS COMPENSATION Outside directors receive an annual retainer of $24,000, plus $1,000 for each Board of Directors or committee meeting attended. Committee chairpersons receive an additional $500 for each committee meeting attended. The Chairman of the Board of Directors receives an additional $25,000 annually for serving in that capacity. Directors who are full-time employees of the Company or its subsidiaries receive no additional compensation for Board of Directors service. Each outside director other than directors Kropid and Wright received on May 8, 1997, options to purchase 2,000 shares of the Company's Common Stock under the provisions of the shareholder approved Option Plan. Directors Kropid and Wright each received on July 15, 1997, options to purchase 1,660 shares of the Company's Common Stock under the provisions of the Option Plan. The purchase price for the options is the market price of the Common Stock on the date of the grant and will become exercisable, in increments over three years, commencing with the first anniversary of the grant. Additional options to purchase 2,000 shares of Common Stock will be granted to each outside director on the date of each Annual Meeting of Shareholders during the 10-year term of the Option Plan. All options granted to the outside directors will expire 10 years after the date of each grant. Outside directors may defer their compensation until retirement or other termination of status as a director. Amounts deferred bear interest at 150% of the Moody's Seasoned Corporate Rate. The Company also provides a retirement plan for its outside directors. With a minimum of 10 years of service, an outside director can retire and receive a benefit equal to the annual retainer, at retirement, for serving on the Company's Board. Directors who retire before age 65, after satisfying the minimum service obligation, will receive retirement benefits upon reaching age 65. COMMITTEES OF THE BOARD In order to assist it in discharging its duties, the Board of Directors has established six permanent committees. The committees consist of Executive, Audit, Compensation, Finance, Nominating, and Pension Plan Investment. The Executive Committee meets, if necessary, to consider corporate policy matters requiring timely action and recommend other matters for consideration and action by the Board of Directors. The Executive Committee consists of Directors Hartley (Chairman), Dyer, Judd, Kropid, Maffie, and Sundt. The Audit Committee, whose functions are discussed above under the caption "Selection of Independent Public Accountants," consists of directors Cortez (Chairman), Batastini, Jager, Lincicome, Sparks, and Wright. The Compensation Committee makes recommendations to the Board of Directors on such matters as directors' fees and benefit programs, executive compensation and benefits, and compensation and benefits for all other Company employees. The committee is also responsible for the executive compensation report and related disclosures contained in this Proxy Statement. The Compensation Committee consists of directors Judd (Chairman), Cortez, Dyer, Hartley, Lincicome, and Wright. The Finance Committee reviews and makes recommendations to the Board of Directors regarding the financial policies, plans, and procedures for the Company and the financial implications of proposed corporate actions. Its responsibilities include reviewing strategies and recommen- 9 14 dations with respect to financing programs, dividend reinvestment and stock purchase programs, and capital structure goals. The Finance Committee consists of directors Lincicome (Chairman), Batastini, Jager, Kropid, and Sparks. The Nominating Committee makes recommendations to the Board of Directors regarding nominees to be proposed by the Board of Directors for election as directors, evaluates the size and composition of the Board of Directors, and establishes the criteria for the selection of directors. In considering candidates for the Board of Directors, the Nominating Committee seeks to achieve an appropriate balance of expertise and diversity of interests recognizing factors such as the character and quality of individuals, experience, age, education, geographic location, anticipated participation in Board of Directors activities, and other personal attributes or special talents. The Nominating Committee will consider written suggestions from shareholders regarding potential nominees for election as directors. To be considered by the Nominating Committee for inclusion in the slate of nominees to be proposed by the Board of Directors, such suggestions should be addressed to the Company's Corporate Secretary. The Nominating Committee also is responsible for recommending Board of Directors committee assignments. The Nominating Committee consists of directors Dyer (Chairman), Hartley, Judd, Kropid, and Sundt. The Pension Plan Investment Committee establishes, monitors, and oversees, on a continuing basis, asset investment policy and practices for the retirement plan. The Pension Plan Investment Committee consists of directors Jager (Chairman), Batastini, Cortez, Sparks, Sundt, and Wright. In 1997, one Executive Committee meeting was held, the Audit Committee held three meetings, the Compensation Committee held three meetings, the Finance Committee held three meetings, the Nominating Committee held two meetings and the Pension Plan Investment Committee held three meetings. EXECUTIVE COMPENSATION AND BENEFITS EXECUTIVE COMPENSATION REPORT The Compensation Committee of the Board of Directors (the "Committee") administers the Company's executive compensation program. Under the supervision of the Committee, the Company has developed and implemented an executive compensation program designed to satisfy the objectives of (i) reasonableness, (ii) competitiveness, (iii) internal equity, and (iv) performance. These objectives are addressed through industry-based compensation comparisons and incentive plans that focus on specific annual and long-term Company financial and productivity performance goals. Base Compensation The nature of the Company's operation has historically led to the use of compensation systems widely used in industry, weighted for utility companies, and accepted by various utility regulatory agencies. Companies of comparable size used to establish the peer group index for the "Performance Graph" were factored into the compensation review. Other utility and general industry surveys were also used to assess the Company's compensation program. Continued use of such systems is designed to address the first three compensation objectives. A range of salaries that are comparable with industry levels provides an objective standard to judge the reasonableness of the Company's salaries, maintains the Company's ability to compete for and retain qualified executive officers, and provides a means for ensuring that responsibilities are properly rewarded. Salaries for the Company's executives are set relative to the midpoint levels for their positions based on this industry comparison. Compensation above these levels is tied to achieving specific financial and productivity performance goals. 10 15 Performance-based Compensation The fourth objective of the Company's compensation program, performance, is addressed through the Company's Management Incentive Plan (the "MIP") and the Option Plan, collectively referred to as the "Incentive Plans." The Incentive Plans are designed to retain key management employees and to focus on specific annual and long-term Company financial and productivity performance goals. Financial, productivity, and customer satisfaction factors are incorporated in the MIP, while the Option Plan is designed to enable executives to benefit from increases in the price of the Company's common stock, thereby aligning their economic interests with those of the Company's shareholders. Under the MIP, an incentive opportunity expressed as a percentage of salary is established annually for each executive officer. The maximum award opportunities cannot exceed 140 percent of the targeted awards for meeting the performance goals. Awards under the MIP are determined based on the Company's annual return-on-equity performance, customers to employee ratios, and customer service satisfaction targets. The financial performance factors used to make this determination involve the average of the Company's return-on-equity performance over the last three years (which is weighted and adjusted for inflation) and the Company's current utility return-on-equity performance in comparison to a peer group of natural gas distribution companies. The productivity performance factors used to make this determination involve an absolute target of Company customers to employee ratio and the actual customers to employee ratio in comparison to a peer group of natural gas distribution companies. Additionally, customer service satisfaction experienced throughout the Company's operating divisions is measured by an independent outside entity. Each of the five factors is equally weighted, and if the threshold percentage for any factor is achieved, a percentage of annual performance awards will have been earned. While the financial factors incorporated in the MIP are significant to shareholder interests, customer satisfaction and productivity factors are significant to customer interests. In prior regulatory proceedings, various commissions insisted that these customer factors be included in the MIP, in order to recover the cost of the program in the Company's natural gas rates. Regardless of whether such awards are earned, no awards will be paid unless the Company's common stock dividend equals or exceeds the prior year's dividend. If annual performance awards are earned and payable, payment of the awards will be subject to a possible downward adjustment depending upon satisfaction of individual performance goals. The Committee will make such a determination for the Company's chief executive officer's individual performance, who in turn will make a like determination for the other executive officers. Further, the annual awards will be split, with 40 percent paid in cash and the remaining 60 percent converted into performance shares tied to the value of the Company's common stock on the date of the awards. The performance shares will be restricted for three years and the ultimate payout in Company common stock will be subject to continued employment. The Company's performance during 1997 exceeded the threshold percentages for each of the established productivity targets. The Company's operations exceeded the target for the internal customers to employee ratio, the customers to employee ratio in comparison to a peer group of natural gas distribution companies, and the customer service satisfaction survey. Grants under the Option Plan were provided to the Company's executive officers during 1997. The options granted were not based upon a predetermined formula, but rather on the Committee's judgment as to the individual's anticipated contribution to the future success of the Company. The number of options granted to the named executive officers in 1997 are shown on the Option Grant Table section of this Proxy Statement. CEO Compensation Compensation paid to Mr. Maffie as president and chief executive officer for 1997 consisted of his base salary and performance award under the MIP. Mr. Maffie's base salary was set relative to 11 16 the midpoint level for salaries paid to chief executive officers of comparable companies, taking into consideration the length of service in his current position, and reflects a 5.6% increase in base salary effective July 7, 1997. Mr. Maffie's performance award under the MIP totaled $330,037 and represented the Company's overall performance in relation to established performance goals. During the year, the Company's performance exceeded each of the established productivity targets, internal customers to employee ratio, customers to employee ratio in comparison to a peer group of natural gas distribution companies, and customer service satisfaction. Mr. Maffie's target performance award for 1997 was set equal to $427,500 or 90% of his annualized December 31, 1997, salary (not the actual salary shown in the Summary Compensation Table), with the award ranging from 14% to 126% of his base annualized salary. Based on the Company's overall 1997 performance in relation to the established goals, Mr. Maffie earned 77.2% of his target award under the MIP, with 40% being paid in cash and 60% in performance shares. Deductibility of Compensation The Company's executive compensation program is being administered to maintain the tax deductibility of all compensation paid to the named executive officers pursuant to Section 162(m) of the Internal Revenue Code (the "Code"). Section 162(m) of the Code provides that compensation paid to the officers in excess of $1,000,000 cannot be deducted by the Company for federal income tax purposes unless, in general, such compensation is performance based, is established by an independent committee of directors, is objective, and the plan or agreement providing for such performance-based compensation has been approved in advance by shareholders or is otherwise exempt from such limitation. The MIP and Option Plan were designed to satisfy these requirements and management believes that the compensation provided thereunder should be deductible. In the future, however, the Company may pay compensation that is non-deductible in limited circumstances if sound management of the Company so requires. The Committee believes that the compensation program addresses the Company's compensation objectives, enhances the commitment of key management employees, and strengthens long-term shareholder value.

- --------------- (1) Forty percent (40%) of the options become exercisable one year after the grant. Thirty percent (30%) of the options become exercisable two years after the grant, with the remaining becoming exercisable on the third anniversary of the grant. (2) The 5% and 10% growth rates for the period ending July 14, 2007, which were determined in accordance with the rules of the SEC, illustrate that the potential future value of the granted options is linked to future increases in growth of the price of the Company's Common Stock. Because the exercise price for the options equals the market price of the Company's Common Stock on the date of the grant, there will be no gain to the named executive officers without an increase in the stock price. The 5% and 10% growth rates are for illustration only and are not intended to be predictive of future growth. - --------------- OPTIONS/SAR EXERCISES AND YEAR-END VALUES Shown below is information with respect to unexercised options granted under the Option Plan to the named executive officers and held by them at December 31, 1997.

- --------------- (1) Years of service beyond 30 years will not increase benefits under the basic retirement plan. (2) For 1998, the maximum annual compensation that can be considered in determining benefits under the Plan is $160,000. For future years the maximum annual compensation will be adjusted to reflect changes in the cost of living as established by the Internal Revenue Service. - --------------- Compensation covered under the basic retirement plan is based on salary depicted in the Summary Compensation Table. As of December 31, 1997, the credited years of service for the named executive officers shown in the Summary Compensation Table are as follows: Mr. Maffie, 19 years; Mr. Biehl, 12 years; Mr. Lowman, 28 years; Mr. Sondeno, 18 years; and Mr. Zub, 19 years. Amounts shown in the pension plan table are straight life annuity amounts notwithstanding the availability of joint survivorship benefit provisions. Benefits paid under the basic and supplemental retirement plans are not reduced by any Social Security benefits received. Supplemental Retirement Plan. The named executive officers also participate in the Company's supplemental retirement plan. Such officers with 10 or more years of service may retire at age 55 or older and will receive benefits under the plan. Benefits from the plan, when added to benefits received under the basic retirement plan, will equal 60% of their highest 12-months of salary, as depicted in the Summary Compensation Table. For Mr. Maffie, compensation used to determine such benefits includes salary, cash bonuses other than the 1996 non-utility bonus, and the payment of restrictive stock awards depicted in the Summary Compensation Table. The cost to the Company for benefits under the supplemental retirement plan for any one of the named executive officers cannot be properly allocated or determined because of the overall plan assumptions and options available. SEVERANCE AND CHANGE IN CONTROL ARRANGEMENTS In July 1996, the Company entered employment agreements (the "Agreements") with seven designated officers, including the named executive officers. These agreements generally provide for the payment, upon termination of employment by the Company without cause, as defined therein, of up to two years of total annual compensation (base salary, a predetermined level of incentive 15 20 compensation and fringe benefits), and up to three years of total annual compensation for Mr. Maffie. The agreements further provide for the payment, upon the termination of employment by such officers for "good reason," as defined therein, within two years following a change in control of the Company, of an amount equal to one and one/half times their total annual compensation other than Mr. Maffie. Under such circumstance, Mr. Maffie would be entitled to a payment equal to three times his total annual compensation. Vesting and payment of benefits under the Supplemental Retirement Plan (described in this Proxy Statement) would also be accelerated if such officers are entitled to benefits under these agreements. If any payment under these agreements will constitute a "parachute payment" subject to any excise tax under the Internal Revenue Code, the officer receiving such payment will be responsible for payment of such tax. The terms of these agreements are for 24 months for each of the designated officers, other than Mr. Maffie, and 36 months for Mr. Maffie, and will be extended for successive one-year periods unless canceled by the Company. 16 21 PERFORMANCE GRAPH The performance graph below compares the five-year cumulative total return on the Company's Common Stock, assuming reinvestment of dividends, with the total returns on the Standard & Poor's 500 Stock Composite Index (S&P 500) and the Edward D.
