A summary of the Plan begins on page 3 of this Prospectus, which should be retained for future reference. Holders of the Company's Common Stock who choose not to participate in the Plan will receive cash dividends, as declared, in the usual manner. Shares of Common Stock needed for the Plan will be purchased either directly from the Company or the open market. The price of shares of Common Stock purchased by participants in the Plan with reinvested dividends, initial investments or optional payments will be (i) in the case of the purchase of authorized but unissued shares of Common Stock from the Company, the composite closing price of the Common Stock on the "Investment Date" as reported on the consolidated tape for New York Stock Exchange listed securities administered by the Consolidated Tape Association (or, if no trading in the Common Stock occurs on such date, the composite closing price on the next preceding date on which trading occurred), and (ii) in the case of the purchase of shares of Common Stock in the open market, the weighted average price (excluding brokerage commissions) paid to obtain them during the "Investment Period." The Common Stock is listed on both the New York and Pacific Stock Exchanges. The annual expenses payable by the Company in connection with the operation of the Plan are approximately $33,000. _________________ THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND EXCHANGE COMMISSION NOR HAS THE COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS.

The Company will provide without charge to each person, including any beneficial owner, to whom a copy of the Prospectus has been delivered, upon the written or oral request of such person, a copy of any or all of the documents referred to above which have been or may be incorporated in this Prospectus by reference, other than certain exhibits to such documents. Written or oral requests for such copies should be directed to: Shareholder Services, Southwest Gas Corporation, P.O. Box 98511, Las Vegas, Nevada 89193-8511, (800) 331-1119 or (702) 876-7280. 2 THE COMPANY The registrant, Southwest Gas Corporation (the "Company"), is incorporated under the laws of the State of California effective March 1931 and is comprised of two operating segments: natural gas operations and financial services. The financial services segment consists of PriMerit Bank, a Federal Savings Bank (the "Bank"), a wholly owned subsidiary, which operates principally in the thrift industry. The executive offices of the Company are located at 5241 Spring Mountain Road, P.O. Box 98510, Las Vegas, Nevada 89193-8510, telephone number (702) 876-7237. USE OF PROCEEDS To the extent that authorized but unissued shares of Common Stock are purchased under the Plan from the Company, the net proceeds from their sale will be used in connection with the Company's construction program, to pay for additional capital improvements to the Company's facilities, and for other corporate purposes. Pending disbursement for this purpose, such proceeds may be used to reduce the amount of the Company's short-term indebtedness. The Company cannot predict how many shares of Common Stock will be sold under the Plan and, therefore, cannot estimate the amount of net proceeds that it will receive. DESCRIPTION OF THE DIVIDEND REINVESTMENT AND STOCK PURCHASE PLAN The Company is offering its shareholders, natural gas customers and employees an opportunity to purchase directly through the Company shares of its Common Stock and to reinvest their Common Stock dividends automatically into shares of Common Stock through the Plan. The following is a detailed description, in question and answer form, of the Plan. For additional information concerning the Plan, you may telephone the Company at (800) 331-1119 or (702) 876-7280. PURPOSE 1. What is the purpose of the Plan? The purpose of the Plan is to provide shareholders, natural gas customers and employees of the Company a simple and convenient method of investing in shares of the Company's Common Stock. Shares purchased under the Plan will be either, (i) authorized but unissued shares purchased from the Company, or (ii) outstanding shares purchased in the open market or through negotiated transactions ("Open Market" or "Open Market Purchases"). The decision to purchase shares on the open market will depend upon the relationship of the purchase price of the shares of Common Stock and book value of such stock. To the extent shares will be purchased directly from the Company, the Company will use the proceeds for its continuing construction program and for other corporate purposes. FEATURES 2. What are the features of the Plan? A natural gas customer or employee of the Company, who is not already a shareholder, may make an initial investment in shares of the Company's Common Stock by making a minimum payment of $100. Thereafter, a participant may invest in additional shares of Common Stock by making an optional payment of no less than $25; provided that the participant's initial investment and/or optional payments in aggregate do not exceed $50,000 per calendar year. 3 Participants must reinvest all of their cash dividends automatically in additional shares of Common Stock of the Company when the total shares owned by a participant are less than 250 shares. Participants with 250 or more shares have the option of receiving one-half of the quarterly dividends in cash. The Company will pay any brokerage commissions or service fees for purchases of Common Stock under the Plan and it will pay all costs for administration of the Plan. Full investment of funds is possible under the Plan because fractions of shares, as well as full shares, will be credited to participants' accounts. In addition, dividends on such fractions, as well as full shares, will be credited to participants' accounts. Regular statements of account will provide simplified record keeping. ADMINISTRATION 3. Who administers the Plan for Participants? The Company administers the Plan, maintains records, sends statements of account to participants and performs other duties relating to the Plan. The Company will appoint an independent agent/trustee ("Trustee") to act as an independent agent for the Plan participants in purchasing and selling shares for participants in the open market or through negotiated transactions. Subject to the objective of obtaining the lowest overall cost of shares purchased, the Trustee will have full discretion as to all matters relating to purchases and sale of such shares. Shares of Common Stock purchased by a participant under the Plan will be registered in the name of a nominee of the Company for participants in the Plan, and will be held by the nominee for participants' accounts until the Company is otherwise instructed by the participant. 4. Where should correspondence regarding the Plan be directed? All correspondence concerning the Plan should be addressed to: Shareholder Services Southwest Gas Corporation P.O. Box 98511 Las Vegas, NV 89193-8511 PARTICIPATION 5. Who may participate in the Plan? All shareholders of record of Common Stock, natural gas customers and employees of the Company are eligible to participate in the Plan. An account may be opened in the participant's own name, in the joint name of the participant and another person, or in the participant's name as custodian for a minor or as trustee for another person by completing the Enrollment and Authorization Form ("Enrollment Form") in the proper manner. If you are a beneficial owner, but not a customer, employee or record owner of Common Stock (that is, if your shares are held for you and registered in a name other than your own, such as in the name of a broker, bank nominee or trustee) and you wish to become a participant in the Plan, you must transfer those shares you desire to be enrolled in the Plan into your own name. Employees whose shares are held in the Company's Employees' Investment Plan ("EIP") do not have to transfer such shares to participate in the Plan. 6. How does a shareholder, natural gas customer or employee join the Plan? If you are a shareholder of record, you may join the Plan by completing and returning an Enrollment Form. 4 If you are a natural gas customer, you may join the Plan by completing an Enrollment Form and returning it along with a minimum initial investment of $100 to the Company. If you are an employee of the Company and participate in the Company's EIP, you may join the Plan by completing and returning an Enrollment Form. If you are an employee of the Company and do not participate in the Company's EIP, you may join the Plan by completing an Enrollment Form and returning it along with a minimum initial investment of $100 to the Company. An Enrollment Form will be furnished to you at any time upon request to Shareholder Services, Southwest Gas Corporation, P.O. Box 98511, Las Vegas, Nevada 89193-8511, or by telephoning the Company at (800) 331-1119 or (702) 876-7280. 7. When can a shareholder, natural gas customer or employee join the Plan? A shareholder of record and an employee who is participating in the Company's EIP may join the Plan at any time. If an Enrollment Form is received on or before the record date for a dividend payment, reinvestment of dividends will begin with that dividend. If the Enrollment Form is received after the record date, reinvestment of dividends will begin with the next dividend payment date. (See Question 10.) Natural gas customers or employees who are not already shareholders can join the Plan at any time. An initial investment of $100 received during any month will be invested as of the next Investment Date or during the next Investment Period. (See Question 9.) With the purchase of Common Stock, such customers or employees will become Plan participants. 8. What does the Enrollment Form provide? The Enrollment Form authorizes the Company to do the following: INITIAL INVESTMENT--Upon receipt of a minimum initial investment payment of $100 from a natural gas customer or employee of the Company, the Company or the Trustee will purchase Common Stock for the account of the customer or employee on the next available Investment Date or during the next Investment Period. (See Question 9.) OPTIONAL PAYMENTS--Upon receipt of optional payments from a minimum of $25 up to a maximum of $50,000 per calendar year, the Company or the Trustee will purchase Common Stock for the participant's account on the next Investment Date or during the next Investment Period. (See Question 11.) DIVIDEND REINVESTMENT--The Company or the Trustee will automatically reinvest dividends on all shares of Common Stock held in Plan accounts on the Investment Date or during the next Investment Period that coincides with the payment of dividends for shares of Common Stock. (See Question 10.) The Company or the Trustee will also automatically reinvest dividends on all of the shares of Common Stock held of record by a participant outside a Plan account. Participants with a total of 250 or more shares of Common Stock will have the option of receiving one-half of their dividends in cash. INITIAL INVESTMENTS 9. When will initial investment payments be invested? The timing for the investment of the initial payments depends upon whether the Common Stock will be purchased directly from the Company, as original issue shares, or in the Open-Market. During periods in which the payments will be invested in original issue shares, purchases will occur twice during the month. During periods in which the payment will be invested in shares purchased on the open-market or through negotiated transactions, purchases will occur once each month. No interest will be paid on payments received and held by the Company prior to investment. 5 ORIGINAL ISSUE PURCHASES--Initial investment payments received by the Company by the 10th day of any month (or the first business day following the 10th, if such day is not a business day) will be invested on the first business day following the 14th day of the month. Initial investment payments received by the Company after the 10th and on or before the 25th day of any month (or the first business day following the 25th, if such day is not a business day) will be invested on the first business day of the following month. Such dates are the "Investment Date(s)" for purposes of the Plan. OPEN-MARKET PURCHASES--Initial investment payments received by the 25th day of any month will be invested by the Trustee during the 30-day period commencing on the 26th day of the month. Such period is the "Investment Period" for the purposes of the Plan. Upon written request received by the Company on or before the Investment Date or the day before the start of the Investment Period in which the initial investment payment is being held by the Company, a participant may, without withdrawing from the Plan, receive the return of a portion of the initial investment payment, provided that a minimum of $100 is maintained in the Plan. REINVESTED DIVIDENDS 10. When will dividends be reinvested? Any dividends on Common Stock to be reinvested will be reinvested on the Investment Date or Investment Period coinciding with the payment of a dividend for shares of Common Stock. Common Stock dividends have ordinarily been paid on the first business day of March, June, September, and December, but no assurance can be given that the Company will continue to pay dividends on this basis. Instructions regarding the automatic reinvestment of dividends on shares of record will be effective on the next dividend payment date if the shareholder's Enrollment Form is received by the Company by the record date (which is normally the 15th calendar day of the month preceding the month in which a dividend is paid) established for a dividend payment. Instructions received after the record date for a dividend will not be effective until the next dividend payment date following the dividend payment date on which the instructions would otherwise have been effective. OPTIONAL PAYMENTS 11. Who is eligible to make optional payments? A participant is eligible to make optional cash payments of at least $25 at any time. An optional cash payment may be made when joining the Plan by enclosing the payment with the Enrollment Form. Thereafter, optional cash payments should be accompanied by the form provided with your statement of account. Optional cash payments can not be less than $25 and can not exceed $50,000 per calendar year per participant. Optional cash payments shall be made by check or money order payable to: Southwest Gas Corporation, P.O. Box 98511, Las Vegas, Nevada 89193-8511, Attention: Shareholder Services. Your Plan account number should be included on all checks. 12. When will optional payments be invested and when will dividends be paid on shares purchased with optional payments? The timing for the investment of optional payments depends upon whether the Common Stock will be purchased directly from the Company, as original issue shares, or in the Open-Market. During periods in which the payments will be invested in original issue shares, purchases will occur twice during the month. During periods in which the payment will be invested in shares purchased on the open-market or through negotiated transactions, purchases will occur once each month. No interest will be paid on payments received and held by the Company prior to investment. 6 ORIGINAL ISSUE PURCHASES--Optional payments received by the Company by the 10th day of any month (or the first business day following the 10th, if such day is not a business day) will be invested on the first business day following the 14th day of the month. Optional payments received by the Company after the 10th and on or before the 25th day of any month (or the first business day following the 25th, if such day is not a business day) will be invested on the first business day of the following month. OPEN-MARKET PURCHASES--Optional payments received by the 25th day of any month will be invested by the Trustee during the Investment Period, the 30-day period commencing on the 26th day of the month. Any dividends on Common Stock purchased with optional payments will be reinvested on the Investment Date coinciding with the payment of a dividend when the Common Stock is purchased directly from the Company. Common Stock dividend payment dates are ordinarily the first business day of March, June, September, and December. No assurance can be given that the Company will continue to pay dividends on this basis. When the shares of Common Stock are purchased on the open market or through a negotiated transaction, the Investment Period will be the 30-day period beginning on the 26th day of the month preceding the dividend date. A participant may, without withdrawing from the Plan, have returned any optional payment upon written request received by the Company on or before the Investment Date or the day before the start of the Investment Period for any payment being held by the Company. 13. How do participants make payments? The amount of the optional payment made each time may vary. However, participants are encouraged to set an investment goal and then send a fixed amount every month or quarter. A payment may be made by enclosing a check or money order payable to Southwest Gas Corporation with the Enrollment Form or on the optional payment form provided with your statement. A payment to be invested must not be included in a check or money order submitted for payment of gas service. EXPENSES 14. Are there any expenses charged to participants in connection with participation in the Plan? There are no expenses charged to participants in connection with purchases of Common Stock under the Plan. All costs of administration of the Plan and any brokerage commissions or service fees incurred resulting from open market purchases of shares of Common Stock or through a negotiated transaction will be paid by the Company. However, if a participant requests that the Company sell his or her shares of Common Stock, any related brokerage commissions or service fees incurred by the Company will be deducted from the proceeds remitted to the participant. PRICING AND PURCHASING OF SHARES 15. How many shares of Common Stock will be purchased for a participant? The number of shares to be purchased for each participant on any Investment Date or during the Investment Period will depend upon the amount of the optional payments received since the last investment in the Plan, the amount of the participant's dividends to be reinvested and the price of the Company's Common Stock on the Investment Date or during the Investment Period. On each Investment Date or at the end of each Investment Period, each participant's account will be credited with that number of shares, including fractional shares computed to four decimal points, equal to the total amount to be invested and reinvested on the participant's behalf, divided by the price of the Common Stock on the Investment Date or during the Investment Period. Fractional shares will earn proportionate dividends as declared. 7 16. How is the price of new shares determined? When purchasing new shares of Common Stock for the Plan from the Company, the price of the shares will be the composite closing price of the Common Stock as reported on the consolidated tape for New York Stock Exchange listed securities administered by the Consolidated Tape Association on the Investment Date or, if no trading in the Common Stock occurs on such date, the composite closing price on the next preceding date on which trading occurred. When purchasing shares of Common Stock for the Plan in the Open Market, the price of the shares will be the weighted average price of all Common Stock acquired by the Trustee during the Investment Period. PARTICIPANTS' ACCOUNTS AND RECORDS 17. What records and accounts will be maintained by the Company for Participants? The Company will maintain an account for each participant. All shares purchased for a participant under the Plan will be credited to his account and held for him. When certificates for shares are issued to a participant or shares are sold for his account pursuant to the Plan, such shares will be withdrawn from his Plan account. 18. What reports will be sent to Participants in the Plan? Each participant in the Plan will receive a quarterly statement of his or her account. Additional monthly statements will be provided to participants that reflect purchases of additional shares with optional cash payments or other account transactions. THESE STATEMENTS ARE A PARTICIPANT'S CONTINUING RECORD OF THE COST OF HIS PURCHASES AND SHOULD BE RETAINED FOR INCOME TAX PURPOSES. In addition, each participant will receive each amended Prospectus for the Plan and copies of all communications sent to all other holders of the Company's Common Stock, including the Company's quarterly reports to shareholders, the annual report to shareholders, notice of annual meeting and proxy statement and tax information with respect to dividends paid. A participant is entitled to vote all shares, including fractional shares, held in his or her Plan account and will receive a Plan proxy enabling him to vote his or her shares. PARTIAL WITHDRAWAL 19. Will certificates be issued for shares of Common Stock purchased under the Plan? Certificates for shares of Common Stock purchased under the Plan will be issued to participants upon their written request to the Company. Upon receipt of such request, certificates for any number of whole shares credited to a participant's Plan account may be withdrawn from the account and issued to the participant. Any remaining full and fractional shares will continue to be credited to the participant's account. Certificates for shares issued to a participant will be registered in the same name or names in which the participant's Plan account is maintained. Dividends on all of the participant's shares, including those shares for which certificates have been issued, will either be reinvested or paid in cash as provided for in the Plan. (See Question 8.) Certificates for fractional shares will not be issued under any circumstances. 20. May a portion of the shares held in the Plan be sold? Yes. Upon receipt of a written request, the Company will withdraw and sell, through the Trustee, any number of whole shares credited to that participant's Plan account; provided, the participant maintains a minimum of 100 shares in his or her account. The participant will be charged any related brokerage commissions or service fees and will receive the proceeds of the sale less these amounts. If the partial withdrawal request is received within three business days of the ex-dividend date for a particular dividend or between such date and the record date for that dividend, it will be processed after the record date. Dividends on the shares to be withdrawn will either be reinvested or paid in cash as provided for in the Plan. (See Question 8.) The participant must 8 have a certified tax identification number on file with the Company on or prior to requesting the sale of shares. 21. May shares in a Plan account be pledged or assigned? Shares credited to the account of a participant may not be assigned or pledged. A participant who wishes to assign or pledge shares must request that certificates for the shares be issued in his or her name. WITHDRAWAL AND TERMINATION 22. When may a participant withdraw from the Plan? A participant may withdraw from the Plan by providing a written request to the Company. Such requests will be processed upon receipt except during the periods commencing three business days prior to the ex-dividend date for a particular dividend through the payment date for that dividend. During that period, such a request will be processed depending upon the time the request is received by the Company. If the request is received within three business days of the ex-dividend date for a particular dividend and on or before the record date for that dividend, the request will be processed after the record date. If the request is received after the record date and on or before the Investment Date or Investment Period for that dividend, the request will not be processed until that dividend is reinvested in the participant's account. (See Question 25.) 23. How does a participant withdraw from the Plan? In order to withdraw from the Plan, a participant must notify the Company in writing and instruct the Company to either issue the whole shares in the participant's account to the participant or deliver the proceeds of sale to the participant. Fractional shares will be sold in all cases. The participant must have a certified tax identification number on file with the Company on or prior to requesting the sale of shares. 24. Can the Company terminate a participant? Yes. The administrative costs to the Company for each customer account do not justify an inactive account. The Company reserves the right to terminate the account of any participant who has not invested and/or reinvested a minimum of $100 in any twelve month period. In addition, the Company reserves the right to terminate the account of any participant if a participant's checks or other form of remittance have not been honored. 25. What happens upon withdrawal, termination or discontinuance? When a participant withdraws from the Plan or when the Company terminates the account of a participant, or upon discontinuance of the Plan by the Company, certificates for all shares credited to the participant's account will be issued and a cash payment will be made for fractional shares. Fractional shares will be sold through the Trustee and any brokerage commissions or service fees will be deducted from the proceeds before the cash payment is made. In the alternative, a participant may request that all of the shares, both whole and fractional, credited to his or her Plan account be sold. If a participant requests a sale, the sale will be made for the account of the participant by the Trustee. If the request is received within three business days of the ex-dividend date for a particular dividend and on or before the record date for that dividend, the request will be processed after the record date. If the request is received after the record date and on or before the Investment Date or Investment Period for that dividend, the request will not be processed until that dividend is reinvested in the participant's account. The participant will be charged any related brokerage commissions or service fees, and will receive the proceeds of the sale less these amounts. If the withdrawal request of a participant is received by the Company on or before the record date for a particular dividend, that dividend and all subsequent dividends upon shares registered in the participant's name will be 9 paid directly to the participant. If the request is received after the record date, the withdrawal request will not be processed until that dividend is reinvested in the participant's account. Once the request is processed, all subsequent dividends upon shares registered in the participant's name will be paid directly to the participant. If the withdrawal request of a participant is received by the Company on or before the Investment Date or the day before the start of the next Investment Period, any payment being held by the Company will be returned. If the request is received after such dates, any payment being held will be reinvested. OTHER INFORMATION 26. How will participants' shares be voted at meetings of shareholders? Participants will receive Plan proxy cards covering total full and fractional shares held under the Plan, enabling them to vote their shares. If a proxy card is returned to the Company properly signed and marked for voting, all the shares covered by such proxy card will be voted as marked. 27. What is the responsibility of the Company and the Trustee under the Plan? The Plan provides that the Company and any Trustee appointed by the Company in administering the Plan will not be liable for any act done in good faith or for any good faith omission to act, including, without limitation, any claim of liability arising out of failure to terminate a participant's Plan participation upon such participant's death prior to receipt of legally sufficient instructions with respect thereto. PARTICIPANTS SHOULD RECOGNIZE THAT NEITHER THE COMPANY NOR THE TRUSTEE CAN ASSURE PARTICIPANTS OF PROFITS OR PROTECT PARTICIPANTS AGAINST LOSSES IN THE VALUE OF THE SHARES PURCHASED UNDER THE PLAN OR ASSURE THE PARTICIPANT OF FUTURE DIVIDENDS. 28. May the Plan be changed or discontinued? The Company reserves the right to suspend, modify or discontinue the Plan at any time and to interpret and regulate the Plan as it deems necessary or desirable in connection with the operation of the Plan. All participants will receive notice of any suspension, modification or termination. The notices will be mailed to the participants at the addresses shown on the Company's record. 29. What happens if the Company makes a rights offering, declares a stock split or issues a stock dividend? As shareholders of record, participants will be notified by the Company of a rights offering. Upon receiving such notification, participants should instruct the Company, on or before the record date established for the rights offering, to issue certificates for those shares for which they wish to exercise rights. If the Company does not receive such instructions, the Trustee will sell on the open market the unexercised rights and proportionally credit participant accounts to the extent such rights are not exercised with the proceeds for investment on the next Investment Date or Investment Period. In the event of a stock split or stock dividend, the Company will proportionally credit to each participant's Plan account the additional shares attributable to his or her interest in the Plan. 30. Can a complete text of the Plan be obtained? Yes, it can be obtained upon request to Shareholder Services. 10 FEDERAL INCOME TAX CONSEQUENCES OF THE PLAN The Company believes the following is an accurate summary of the tax consequences of participation in the Plan as of the date of this Prospectus. This summary may not reflect every possible situation that could result from participation in the Plan, and, therefore, participants in the Plan are advised to consult their own tax advisors with respect to the tax consequences (including federal, state, local and other tax laws and U.S. tax withholding laws) applicable to their particular situations. In general, the amount of cash dividends paid by the Company is includable in income even though reinvested under the Plan. Under this general rule, the cost basis for federal income tax purposes of any shares acquired through the Plan will be the price at which the shares are credited to the account of the participant as described in the section entitled Pricing and Purchasing of Shares. In connection with open market purchases, brokerage commissions paid by the Company on a participant's behalf are to be treated as distributions subject to income tax in the same manner as dividends. The amounts paid for brokerage commissions are, however, includable in the cost basis of shares purchased. The information return sent to participants and the IRS at year-end, if so required, will show such amounts paid on their behalf. A U.S. shareholder electing to participate in the Plan must provide his Taxpayer Identification Number (generally, an individual's Social Security Number) or certify that they are exempt from backup withholdings. Failure to provide a correct Taxpayer Identification Number will result in backup withholdings of 31 percent. Withholding may also occur upon notification from the Internal Revenue Service directing the Plan to institute backup withholdings. A foreign shareholder who is a participant and whose dividends are subject to United States income tax withholding will have the amount of the tax to be withheld deducted from such dividends before reinvestment in additional shares for such participant's Plan account. The statements confirming purchases made for a foreign participant will indicate that tax has been withheld. The final statement received from the Company during any calendar year will include information for that year regarding total dividends paid on Plan shares. In addition, the Company will send each participant an IRS Form 1099- Dividend at year-end showing total dividends paid on shares held of record. Both statements should be retained for tax reporting purposes. INTERESTS OF NAMED EXPERTS AND COUNSEL Robert M. Johnson, Esq., Associate General Counsel for the Company, has given an opinion to the Commission upon the validity of the shares of Common Stock being registered. Mr. Johnson is employed by the Company on a full-time basis. The financial statements incorporated by reference in this Registration Statement have been audited by Arthur Andersen LLP, independent public accountants, as indicated in their report included in the Annual Report on Form 10-K for the year ended December 31, 1994, and are included herein in reliance upon the authority of said firm as experts in accounting and auditing in giving said report. DISCLOSURE OF SECURITIES AND EXCHANGE COMMISSION POSITION ON INDEMNIFICATION FOR SECURITIES ACT LIABILITIES Section 317 of California's General Corporation Law authorizes a court to award, or a corporation's Board of Directors to grant, indemnification to directors, officers and other agents in terms sufficiently broad to permit indemnification under certain circumstances for liabilities, including expenses, arising in connection with the Securities Act of 1933, as amended. Pursuant to the Articles of Incorporation and the Bylaws of the Company, and in accordance with applicable law, directors and officers of the Company are generally indemnified against judgments, expenses and other amounts 11 actually and reasonably incurred by or imposed upon them in connection with or arising out of any action in which they were or are parties or are threatened to be made parties by reason of their being or having been a director or officer of the Company. In addition, the Company has entered into indemnification agreements with certain officers and directors which provide for indemnification to the full extent permitted by California law. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers or persons controlling the Company, the Company has been informed that in the opinion of the Commission such indemnification is against public policy as expressed in the Act and is therefore unenforceable. 12 ====================================== ====================================== No dealer, salesperson or other individual has been authorized to give any information or to make any representations other than those contained or incorporated by reference in this Prospectus in connection with the offer made by this Prospectus and, if given or made, such information or representations must not be relied upon as having been authorized by the [SWG LOGO] Company or any agent, dealer or underwriter.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS Section 317 of the General Corporation Law of California provides that a corporation has the power, and in some cases is required, to indemnify an agent, including a director or officer, who was or is a party or is threatened to be made a party to any proceeding, against certain expenses, judgments, fines, settlements and other amounts under certain circumstances. Article VIII of the Registrant's Bylaws provides for the indemnification of directors, officers and agents as allowed by statute. In addition, the Registrant has purchased directors and officers insurance policies which provide insurance against certain liabilities for directors and officers. ITEM 16. EXHIBITS.

UNDERTAKINGS. The undersigned Registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a posteffective amendment to this Registration Statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, unless the information required to be included in such posteffective amendment is contained in a periodic II-1 report filed by Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 and incorporated herein by reference; (ii) To reflect in the Prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent posteffective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement, unless the information required to be included in such posteffective amendment is contained in a periodic report filed by Registrant pursuant to Section 13 or Section 15(d) of the Securities Act of 1934 and incorporated herein by reference; (iii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement; (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such posteffective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; (3) To remove from registration by means of a posteffective amendment any of the securities being registered which remain unsold at the termination of the offering. (4) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the Registration Statement shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the provisions described in Item 15 above, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue. II-2 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Las Vegas, State of Nevada, on the 6th day of March, 1995.

                          SOUTHWEST GAS CORPORATION
                DIVIDEND REINVESTMENT AND STOCK PURCHASE PLAN


1.     Purpose
       -------

       The purpose of the Plan is to provide shareholders, natural gas customers
       and employees of the Company a simple and convenient method of investing
       in shares of the Company's Common Stock.  Shares purchased under the Plan
       will be either, (i) authorized but unissued shares purchased from the
       Company or (ii) outstanding shares purchased in the open market or
       through negotiated transactions ("Open Market" or "Open Market
       Purchases").  The decision to purchase shares on the Open Market will
       depend upon the relationship of the market price and book value of the
       Common Stock.  To the extent shares are purchased directly from the
       Company, the Company will use the proceeds for its continuing
       construction program and for other corporate purposes.


2.     Participation
       -------------

       2.1  Company shareholders of record, natural gas customers and employees
            of the Company are eligible to participate in the Plan.  Beneficial
            owners whose shares are held by brokers in street names (or
            otherwise registered in names other than their own), to be eligible
            to participate in the Plan, must withdraw their shares from the
            street name or other names and register them in their own name. 
            Employees whose shares are held by the Company's Employees'
            Investment Plan ("EIP") do not have to withdraw the shares from the
            EIP to participate in the Plan.

       2.2  An account may be opened in the participant's own name, in the joint
            name of the participant and another person, or in the participant's
            name as custodian for a minor or as trustee for another person by
            completing the "Enrollment and Authorization Form" (Enrollment Form)
            in the proper manner.    

       2.3  An Enrollment Form will be furnished to you at any time upon request
            to Shareholder Services, Southwest Gas Corporation, P.O. Box 98511,
            Las Vegas, Nevada 89193-8511, or by telephoning the Company at
            (702) 876-7280 or (800) 331-1119.


3.     Plan Enrollment
       ---------------

       3.1  Shareholders of record and employees who are participating in the
            Company's EIP may join the Plan at any time by completing and

            returning an Enrollment Form.  Natural gas customers and other
            employees may join the Plan at any time by completing an Enrollment
            Form and returning it along with a minimum initial investment of
            $100 to the Company. 

       3.2  The Enrollment Form authorizes the Company to do the following:

            (a)  INITIAL INVESTMENT--Upon receipt of a minimum initial
                 investment payment of $100 from a natural gas customer or
                 employee of the Company, the Company or the Trustee will
                 purchase Common Stock for the account of the customer or
                 employee on the next Investment Date or during the next
                 Investment Period. 

            (b)  OPTIONAL PAYMENTS--Upon receipt of optional payments from a
                 minimum of $25 up to a maximum of $50,000 per calendar year,
                 the Company or the Trustee will purchase Common Stock for the
                 participant's account on the next Investment Date or during the
                 next Investment Period. 

            (c)  DIVIDEND REINVESTMENT--The Company or the Trustee will
                 automatically reinvest dividends on all shares of Common Stock
                 held in Plan accounts on the Investment Date or during the
                 Investment Period that coincides with the payment of dividends
                 for shares of Common Stock.  The Company or the Trustee will
                 also automatically reinvest dividends on all of the shares of
                 Common Stock held of record by a participant outside of the
                 Plan.  Participants with a total of 250 or more shares of
                 Common Stock will have the option of receiving one-half of
                 their dividends in cash.


4.     Investment of Initial and Optional Payments
       -------------------------------------------

       4.1  The timing for the investment of the initial and optional payments
            depends upon whether the Common Stock will be purchased directly
            from the Company, as original issue shares, or in the Open Market. 
            During periods in which the payments will be invested in original
            issue shares, purchases will occur twice during the month.  During
            periods in which the payments will be invested in shares purchased
            in the Open Market, purchases will occur once each month.

            (a)  ORIGINAL ISSUE PURCHASES--Initial and optional payments
                 received by the Company by the 10th day of any month (or the
                 first business day following the 10th, if such day is not
                 business day) will be invested on the first business day
                 following the 14th day of the month.  Initial investment
                 payments received by the Company after the 10th and on or
            
                                       2
            
                 before the 25th day of any month (or the first business day
                 following the 25th, if such day is not a business day) will be
                 invested as of the first business day of the following month. 
                 Such dates are the "Investment Date" for purposes of the Plan.

            (b)  OPEN-MARKET PURCHASES--Initial and optional payments received
                 by the 25th day of any month will be invested by the Trustee
                 during the 30-day period commencing on the 26th day of the
                 month.  Such period is the "Investment Period" for the purposes
                 of the Plan. 

       4.2  Common Stock acquired with initial and optional payments will be
            original issue Common Stock, so long as the market price of the
            Company's Common Stock exceeds seventy-five percent (75%) of the
            book value of the Common Stock, as determined on a quarterly basis.
  
       4.3  Upon written request received by the Company on or before the next
            Investment Date or the day before the start of the next Investment
            Period in which the initial payment is being held by the Company, a
            customer or an employee may receive the return of the initial
            payment and become a participant in the Plan, provided that a
            minimum of $100 is maintained in the Plan.  If the customer or
            employee requests the entire return of the initial payment, the
            payment will be returned and the individual will no longer be
            enrolled in the Plan.

       4.4  Upon written request received by the Company on or before the next
            Investment Date or the day before the start of the next Investment
            Period in which the optional payment is being held by the Company, a
            participant may, without withdrawing from the Plan, receive the
            return of all or part of the optional payment.

       4.5  No interest will be paid on payments received and held by the
            Company before investment.


5.     Reinvestment of Dividends
       -------------------------

       5.1  Dividends on Common Stock held by a Plan participant, including
            proportionate dividends on fractional shares, will be reinvested on
            the Investment Date or Investment Period coinciding with the payment
            of a dividend for shares of Common Stock.  Common Stock dividends
            have ordinarily been paid on the first business day of March, June,
            September and December but no assurance can be given that the
            Company will continue to pay dividends on this basis.  When the
            shares of Common Stock are purchased in the Open Market with
       
                                       3

            reinvested dividends, the Investment Period will be the 30-day
            period beginning on the 26th day of the month preceding the dividend
            date.  

       5.2  Common Stock acquired with reinvested dividends will be original
            issue Common Stock, so long as the market price of the Company's
            Common Stock exceeds seventy-five percent (75%) of the book value of
            the Common Stock, as determined on a quarterly basis.       
  
       5.3  Dividends on shares of record will be reinvested effective on the
            next dividend payment date if the shareholder's Enrollment Form is
            received by the Company by the record date (which is normally the
            15th calendar day of the month preceding the month in which a
            dividend is paid) established for a dividend payment.  Instructions
            received after the record date for a dividend will not be effective
            until the next dividend payment date following the dividend payment
            date.

       5.4  Participants must reinvest all of their dividends automatically in
            additional shares of Common Stock of the Company when the total
            shares owned by a participant is less than 250 shares.  Participants
            with 250 or more shares have the option of receiving one-half of the
            quarterly dividends in cash.


6.     Pricing and Purchasing of Shares
       --------------------------------

       6.1  The number of shares to be purchased for each participant on any
            Investment Date or during the Investment Period will depend upon the
            amount paid by the participant preceding the Investment Date, the
            amount of the participant's dividends to be reinvested and the price
            of the Company's Common Stock on the Investment Date or during the
            Investment Period.  On each Investment Date or at the end of each
            Investment Period, each participant's account will be credited with
            that number of shares, including fractional shares computed to four
            decimal points, equal to the total amount to be invested and
            reinvested on the participant's behalf, divided by the price of the
            Common Stock on the Investment Date or during the Investment Period.
       

       6.2  When purchasing new shares of Common Stock for the Plan from the
            Company, the price of the shares will be the composite closing price
            of the Common Stock as reported on the consolidated tape for New
            York Stock Exchange listed securities administered by the
            Consolidated Tape Association on the Investment Date or, if no
            trading in the Common Stock occurs on such date, the composite
            closing price on the next preceding date on which trading occurred.
       
                                       4

       6.3  When purchasing shares of Common Stock for the Plan in the Open
            Market, the price of the shares will be the weighted average price
            of all Common Stock acquired by the Trustee during the Investment
            Period.


7.     Partial Plan Withdrawal
       -----------------------

       7.1  Certificates for shares of Common Stock purchased under the Plan
            will be issued to participants upon their written request to the
            Company.  Upon receipt of such request, certificates for any number
            of whole shares credited to a participant's Plan account may be
            withdrawn from the account and issued to the participant.  Any
            remaining full and fractional shares will continue to be credited to
            the participant's account.  Certificates for shares issued to a
            participant will be registered in the same name or names in which
            the participant's Plan account is maintained.  Dividends on all of
            the participant's shares, including those shares for which
            certificates have been issued, will either be reinvested or paid in
            cash as provided for in the Plan.  Certificates for fractional
            shares will not be issued under any circumstances.

       7.2  Upon receipt of a written request, the Company will withdraw and
            sell, through the Trustee, any number of whole shares credited to
            that participant's Plan account; provided, the participant maintains
            a minimum of 100 shares in his account. The participant will be
            charged any related brokerage commissions or service fees and will
            receive the proceeds of the sale less these amounts.

       7.3  If the partial withdrawal request is received within three business
            days of the ex-dividend date for a particular dividend or between
            such date and the record date for that dividend, it will be
            processed after the record date.  Dividends on the shares to be
            withdrawn will either be reinvested or paid in cash as provided for
            in the Plan.  The participant must have a certified tax
            identification number on file with the Company before the shares
            will be sold.

       7.4  Shares credited to the account of a participant may not be assigned
            or pledged.  A participant who wishes to assign or pledge shares
            must withdraw such shares from the Plan.


8.     Plan Withdrawal or Termination
       ------------------------------

       8.1  A participant may withdraw from the Plan by providing a written
            request to the Company.  Such requests will be processed upon
            receipt except during the periods commencing three business days
            prior to the ex-dividend date for a particular dividend through the
            payment date for that dividend.  During that period, such a request
       
                                       5

            will be processed depending upon the time the request is received by
            the Company.  If the request is received within three business days
            of the ex-dividend date for a particular dividend and on or before
            the record date for that dividend, the request will be processed
            after the record date.  If the request is received after the record
            date and on or before the Investment Date or Investment Period for
            that dividend, the request will not be processed until that dividend
            is reinvested in the participant's account.  

       8.2  When a participant withdraws from the Plan or when the Company
            terminates the account of a participant, or upon discontinuance of
            the Plan by the Company, certificates for all shares credited to the
            participant's account will be issued and a cash payment will be made
            for fractional shares.  Fractional shares will be sold through the
            Trustee and any brokerage commissions or service fees will be
            deducted from the proceeds before the cash payment is made. 

       8.3  A participant may request that all of the shares, both whole and
            fractional, credited to his Plan account be sold.  If a participant
            requests a sale, the sale will be made for the account of the
            participant by the Trustee.  A sale request will be processed as
            provided for in Section 8.1 above.  The participant will be charged
            any related brokerage commissions or service fees, and will receive
            the proceeds of the sale less these amounts.

       8.4  If the withdrawal request of a participant is received by the
            Company on or before the record date for a particular dividend, that
            dividend and all subsequent dividends upon shares registered in the
            participant's name will be paid directly to the participant.  If the
            request is received after the record date, the withdrawal request
            will not be processed until that dividend is reinvested in the
            participant's account.  Once the request is processed, all
            subsequent dividends upon shares registered in the participant's
            name will be paid directly to the participant.

       8.5  If the withdrawal request of a participant is received by the
            Company on or before the next Investment Date or the day before the
            start of the next Investment Period, any payment being held by the
            Company will be returned.  If the request is received after such
            dates, any payment being held will be reinvested under the Plan.

       8.6  The Company reserves the right to terminate the account of any
            participant who has not invested and/or reinvested a minimum of $100
            in any twelve month period.  In addition, the Company reserves the
            right to terminate the account of any participant if a participant's
            checks or other form of remittance have not been honored.
       
                                       6

9.     Plan Expenses
       -------------

       There are no expenses charged to participants in connection with
       purchases of Common Stock under the Plan.  All costs of administration of
       the Plan and any brokerage commissions or service fees incurred resulting
       from Open Market Purchases of shares of Common Stock will be paid by the
       Company.  However, if a participant requests that the Company sell his
       shares of Common Stock, any related brokerage commissions or service fees
       incurred by the Company will be deducted from the proceeds remitted to
       the participant.


10.    Participant Accounts and Records
       --------------------------------

       10.1 The Company will maintain an account for each participant.  All
            shares purchased for a participant under the Plan will be credited
            to his account and held for him.  When certificates for shares are
            issued to a participant or shares are sold for his account pursuant
            to the Plan, such shares will be withdrawn from his Plan account.

       10.2 Each participant in the Plan will receive a quarterly statement of
            his account.  Additional monthly statements will be provided to
            participants to reflect optional cash purchases or other account
            transactions.  Such statements are a participant's continuing record
            of the cost of his purchases and should be retained for income tax
            purposes.  

       10.3 In addition, participants will receive each amended Prospectus for
            the Plan and copies of all communications sent to all other holders
            of the Company's Common Stock, including the Company's quarterly
            reports to shareholders, the annual report to shareholders, notice
            of annual meeting and proxy statement and tax information with
            respect to dividends paid.  


11.    Custody of Shares and Shareholder Voting
       ----------------------------------------

       11.1 Shares of Common Stock purchased by a participant under the Plan
            will be registered in the name of a nominee of the Company for
            participants, and will be held by the nominee for participants'
            accounts until the Company is otherwise instructed by the
            participant.

       11.2 Shares credited to a participant's account, including fractional
            shares, will be voted as the participant directs. Participants will
            receive Plan proxy cards covering total full and fractional shares
            held under the Plan, enabling them to vote their shares in
            connection with any annual or special meeting of shareholders.  If a
            
                                       7
            
            proxy card is returned to the Company properly signed and marked for
            voting, all the shares covered by such proxy card will be voted as
            marked.

       11.3 As in the case of shareholders who are not participating in the
            Plan, if no instructions are indicated on a properly signed and
            returned proxy card, all of the participant's shares credited to his
            Plan account will be voted in accordance with the recommendations of
            the Company.  If the Plan proxy card is not returned, a
            participant's shares may be voted only if the participant or a duly
            appointed representative votes in person at the meeting. 


12.    Rights Offering, Stock Dividends and Stock Splits
       -------------------------------------------------

       12.1 As shareholders of record, participants will be notified by the
            Company of a rights offering.  Upon receiving such notification,
            participants should instruct the Company, on or before the record
            date established for the rights offering, to issue certificates for
            those shares for which they wish to exercise rights.  If the Company
            does not receive such instructions, the Trustee will sell on the
            open market the unexercised rights and proportionally credit
            participant accounts to the extent such rights are not exercised
            with the proceeds for investment on the next Investment Date or
            Investment Period.

       12.2 In the event of a stock split or stock dividend, the Company will
            proportionally credit to each participant's Plan account the
            additional shares attributable to his interest in the Plan.


13.    Administration
       --------------

       13.1 The Plan shall be administered by the Company's Board of Directors.
            The Board will have full power to administer the Plan and shall
            determine questions of interpretation or policy.  Further, the Board
            has the authority to delegate its responsibilities under the Plan to
            individual officers of the Company, who may, in turn, delegate the
            day-to-day administration of the Plan to the Shareholder Services
            department of the Company.

       13.2 The Board will appoint an independent agent/trustee ("Trustee") to
            act as an independent agent for the Plan participants in purchasing
            and selling shares for participants in the Open Market.  The Trustee
            will, subject to the objective of obtaining the lowest overall cost
            of shares purchased, have full discretion as to all matters relating
            to the purchase and sale of such shares.
            
                                       8

14.    Amendment, Termination and Suspension of the Plan
       -------------------------------------------------

       14.1 The Board of Directors has the right at any time and from time to
            time to adopt written amendments, amending in whole or in part, any
            provision of the Plan.  The Board also has the right to adopt a
            written amendment to suspend or terminate the Plan in whole or in
            part at any time.  All Participants will receive notice of any
            amendment, suspension or termination of the Plan.  The notices will
            be mailed to the participants at the addresses shown on the
            Company's record.

       14.2 If the Plan is terminated, shares in the Plan accounts will be
            issued or sold as provided for in Section 8 above.


15.    Responsibility of the Company and Trustee
       -----------------------------------------

       15.1 The Plan provides that the Company and any Trustee appointed by the
            Company in administering the Plan will not be liable for any act
            done in good faith or for any good faith omission to act, including,
            without limitation, any claim of liability: (i) arising out of
            failure to terminate a participant's Plan participation upon such
            participant's death prior to receipt of legally sufficient
            instructions with respect thereto; (ii) with respect to the prices
            at which shares of Common Stock are purchased or sold for the
            participant's account and the times when such purchases or sales are
            made; or (iii) with respect to any fluctuation in the market value
            after the purchase or sale of shares.

       15.2 Participants should recognize that neither the Company nor the
            Trustee can assure participants of profits, protect participants
            against losses in the value of the shares purchased under the Plans
            or assure participants of future dividends.


16.    Tax Withholdings on Dividends
       -----------------------------

       16.1 A U.S. shareholder electing to participate in the Plan must provide
            his Taxpayer Identification Number (generally, an individual's
            Social Security Number) or certify that they are exempt from backup
            withholdings.  Failure to provide a correct Taxpayer Identification
            Number will result in backup withholdings of a participant's
            dividends, as prescribed by applicable provisions of the Internal
            Revenue Code.  Withholding may also occur upon notification from the
            Internal Revenue Service directing the Plan to institute backup
            withholdings.
            
                                       9

       16.2 A foreign shareholder who is a participant and whose dividends are
            subject to United States income tax withholding will have the amount
            of the tax to be withheld deducted from such dividends before
            reinvestment in additional shares for such participant's Plan
            account.  The statements confirming purchases made for a foreign
            participant will indicate that tax has been withheld.

       16.3 The final statement received from the Company during any calendar
            year will include information for that year regarding total
            dividends paid on Plan shares.  In addition, the Company will send
            each participant an IRS Form 1099-Dividend at year-end showing total
            dividends paid on shares held of record.  Both statements should be
            retained for tax reporting purposes.


17.    Miscellaneous
       -------------

       17.1 This Plan is purely voluntary on the part of the Company. Neither
            the Plan's establishment nor any amendment nor the creation of any
            Plan account will be construed as giving participants any legal or
            equitable rights against the Company or the Trustee unless
            specifically provided for in the Plan or conferred by affirmative
            action of the Company or the Trustee according to the terms and
            provisions of the Plan.  Such actions will not be construed as
            giving any employee the right to be retained in the service of the
            Company.

       17.2 Whenever any words are used herein in the masculine gender, they
            will be construed as though they were also used in the feminine
            gender in all cases where they would apply, and vice versa. 
            Whenever any words are used herein in the singular form, they will
            be construed as though they were also used in the plural form in all
            cases where they would apply, and vice versa.

       17.3 The Plan will be governed by and construed according to the federal
            laws governing dividend reinvestment and stock purchase plans and
            according to the laws of the State of California where such laws are
            not in conflict with the aforementioned federal laws.

       IN WITNESS WHEREOF, Southwest Gas Corporation has adopted this amended
and restated Plan effective March 7, 1995.

March 14, 1995



Southwest Gas Corporation
P.O. Box 98510
Las Vegas, NV  89193-8510

Ladies and Gentlemen:

As Counsel for Southwest Gas Corporation ("Company"), I have examined the
Registration Statement on Form S-3 to be filed by the Company with the
Securities and Exchange Commission in connection with the registration under
the Securities Act of 1933, as amended, of 1,200,000 shares of the Company's
$1 par value Common Stock ("Stock") pursuant to the Company's Dividend
Reinvestment and Stock Purchase Plan.  I also have examined the proceedings
heretofore taken by the Company and its Board of Directors in connection with
the authorization and proposed issuance and sale of the Stock, and I am
familiar with the forms of resolutions adopted and further actions proposed to
be taken by the Board of Directors of the Company in connection therewith.  I
also am familiar with the application filed by the Company with the California
Public Utilities Commission for authority to issue the Stock, and the order
issued by said Commission authorizing the issuance thereof.

Based upon the foregoing and upon such other matters as I deem relevant in the
circumstances, it is my opinion that the Company has received all required
authorizations from state regulatory agencies having jurisdiction over the
issuance of the Stock by the Company, and that, subject to the actions
authorized by the Company's Board of Directors being taken, the Stock, upon
issuance and sale thereof in the manner specified in the Registration
Statement, will be duly authorized, legally issued fully paid and
nonassessable outstanding Stock of the Company.

I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement, and I further consent to the use of my name under the
caption "Interests of Named Experts and Counsel" in the Registration Statement
and the Prospectus which forms a part thereof.
