Ladies and Gentlemen:

Southwest Gas Corporation, a California corporation (the "Company"), confirms its agreement with Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated, Dean Witter Reynolds Inc. and PaineWebber Incorporated (each, an "Agent" and collectively, the "Agents") with respect to the issue and sale by the Company of its Medium-Term Notes, Series A due nine months or more from date of issue (the "Notes"). The Notes are to be issued pursuant to an Indenture, dated as of July 15, 1996, as amended, supplemented or modified from time to time including by the Second Supplemental Indenture dated as of December 30, 1996 (as so amended, supplemented or modified, the "Indenture"), between the Company and Harris Trust and Savings Bank, as trustee (the "Trustee"). As of the date hereof, the Company has authorized the issuance and sale of up to $150,000,000 aggregate initial offering price of Notes to or through the Agents pursuant to the terms of this Agreement. It is understood, however, that the Company may from time to time authorize the issuance of additional Notes and that such additional Notes may be sold to or through the Agents pursuant to the terms of this Agreement, all as though the issuance of such Notes were authorized as of the date hereof.


The Company has filed with the Securities and Exchange Commission (the "SEC") in accordance with the provisions of the Securities Act of 1933, as amended (the "1933 Act"), a registration statement on Form S-3 (File No. 33- 55621) (the "1994 Registration Statement") for the offering from time to time in accordance with Rule 415 of the rules and regulations of the SEC under the 1933 Act (the "1933 Act Regulations") of its debt securities, preferred stock and/or common stock having an aggregate offering price of $300,000,000 and the 1994 Registration Statement has become effective. While an aggregate offering price of $270,112,800 of such securities remained unsold under the 1994 Registration Statement, the Company and Southwest Gas Capital I, a statutory business trust organized under the Business Trust Act of the State of Delaware (the "Trust"), filed with the SEC a registration statement on Form S-3 (No. 33-62143), as amended (the "1995 Registration Statement"), under the 1933 Act for the offering from time to time in accordance with Rule 415 of the 1933 Act Regulations of the Company's debt securities, preferred stock and/or common stock and the Trust's preferred securities and related guarantee of preferred securities by the Company having an aggregate offering price of $270,400,000 and the 1995 Registration Statement has become effective. While an aggregate offering price of $60,400,000 of such securities remained unsold under the 1994 Registration Statement and the 1995 Registration Statement, the Company filed with the SEC a registration statement on Form S-3 (No. 333-14605)(the "1996 Registration Statement"), under the 1933 Act for the offering from time to time in accordance with Rule 415 of the 1933 Act Regulations of its debt securities, including the Notes, preferred stock and/or common stock having an aggregate offering price of $250,000,000 (all of which securities remain unsold) and the 1996 Registration Statement has become effective. The 1994 Registration Statement, the 1995 Registration Statement and the 1996 Registration Statement (and any further registration statements that may be filed by the Company for the purpose of registering additional Notes and in connection with which this Agreement is included or incorporated by reference as an exhibit) and the combined prospectus constituting a part of the 1996 Registration Statement pursuant to Rule 429 of the 1933 Act Regulations, and any prospectus supplement (a "Prospectus Supplement") and pricing supplement (a "Pricing Supplement") relating to the Notes, including all documents that are filed by the Company with the SEC under the Securities Exchange Act of 1934, as amended (the "1934 Act"), or the rules and regulations of the SEC under the 1934 Act (the "1934 Act Regulations") that are at any time incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act (the "Incorporated Documents"), as from time to time amended or supplemented by the filing of documents pursuant to the 1934 Act, the 1934 Act Regulations, the 1933 Act, the 1933 Act Regulations or otherwise, are referred to herein as the "Registration Statements" and the "Prospectus," respectively, except that if any revised prospectus shall be provided to the Agents by the Company for use in connection with the offering of the Notes, whether or not such revised prospectus is required to be filed by the Company pursuant to Rule 424(b) of the 1933 Act Regulations, the term "Prospectus" shall refer to such revised prospectus from and after the time it is first provided to the Agents for such use.

All references in this Agreement to financial statements and schedules and other information that is "contained," "included" or "stated" in the Registration Statements or the Prospectus (and all other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information that are or are deemed to be incorporated by reference in the Registration Statements or the Prospectus, as the case may be; and all


references in this Agreement to amendments or supplements to the Registration Statements or the Prospectus shall be deemed to mean and include the filing of any Incorporated Document after the time of execution of this Agreement; provided, however, that any supplement to the Prospectus filed with the SEC pursuant to Rule 424(b) of the 1933 Act Regulations with respect to an offering of securities of the Company, other than the Notes, or the Trust shall not be deemed to be a supplement to, or a part of, the Prospectus.

SECTION 1. Appointment as Agent.

(a) Appointment. Subject to the terms and conditions stated herein and subject to the reservation by the Company of the right to sell Notes directly on its own behalf, the Company hereby agrees that Notes will be sold exclusively to or through the Agents. The Company may from time to time offer and sell Notes otherwise than through an Agent; provided, however, that so long as this Agreement shall be in effect, (i) the Company shall not solicit offers to purchase Notes through any agent without (A) amending this Agreement to appoint such agent as an additional Agent hereunder on the same terms and conditions as provided herein for the Agents and (B) giving the Agents prior notice of such appointment and (ii) the Company may accept any offer to purchase Notes through any agent other than an Agent, provided that (A) the Company shall not have solicited such offer, (B) the Company and such agent shall have entered into an agreement with respect to such purchase having terms and conditions (including, without limitation, any commissions with respect thereto) in substance identical to the terms and conditions that would apply to such purchase under this Agreement if such agent were an Agent hereunder, which may be effected by incorporating the terms and conditions of this Agreement by reference into such agreement in the form of Exhibit B hereto, and
(C) the Company shall provide the Agents with notice of such offer to purchase, together with a copy of such agreement, promptly following the acceptance thereof.

(b) Sale of Notes. The Company shall not sell or approve the solicita- tion of purchases of Notes in excess of the amount that shall be authorized by the Company and the Public Utilities Commission of the State of California (the "CPUC") from time to time or in excess of the aggregate initial offering price of Notes registered pursuant to the Registration Statements. The Agents shall have no responsibility for maintaining records with respect to the aggregate initial offering price of Notes sold, or of otherwise monitoring the availability of Notes for sale, under the Registration Statements or applicable CPUC authorizations.

(c) Purchases as Principal. The Agents shall not have any obligation to purchase Notes from the Company as principal, but one or more Agents may agree from time to time to purchase Notes as principal for resale to investors and other purchasers determined by such Agent or Agents. Any such purchase of Notes by an Agent as principal shall be made in accordance with Section 3(a) hereof.

(d) Solicitations as Agent. If agreed upon by an Agent and the Company, such Agent, acting solely as agent for the Company and not as principal, will solicit purchases of the Notes. Such Agent will communicate to the Company, orally, each offer to purchase Notes solicited by it on an agency basis, other than those offers rejected by such Agent. Such Agent shall have the right, in its discretion reasonably exercised, to reject any proposed purchase of Notes, as a whole or in part, and any such rejection shall not be deemed a breach of its agreement contained herein. The Company may accept or reject any proposed purchase of Notes, in whole or in part. Such Agent shall make reasonable efforts to assist the Company in obtaining performance by each purchaser whose offer to purchase Notes has been solicited by it and accepted by the Company. Such Agent shall not have any liability to the Company in the event that any such purchase is not consummated for any reason. If the Company shall default on its obligation to deliver Notes to a purchaser whose offer it has accepted, the Company shall (i) hold such Agent harmless against any loss, claim or damage arising from or as a result of such default by the Company and (ii) pay to such Agent any commission to which it would otherwise be entitled absent such default.


(e) Reliance. The Company and the Agents agree that any Notes purchased by one or more Agents as principal shall be purchased, and any Notes the placement of which an Agent arranges as agent shall be placed by such Agent, in reliance on the representations, warranties, covenants and agreements of the Company contained herein and on the terms and conditions and in the manner provided herein.

SECTION 2. Representations and Warranties.

(a) The Company represents and warrants to each Agent as of the date hereof, as of the date of each acceptance by the Company of an offer for the purchase of Notes (whether to such Agent as principal or through such Agent as agent), as of the date of each delivery of Notes (whether to such Agent as principal or through such Agent as agent) (the date of each such delivery to the Agent as principal being hereafter referred to as a "Settlement Date"), and as of any time that the Registration Statements or the Prospectus shall be amended or supplemented or there is filed with the SEC any Incorporated Document (each of the times referenced above being referred to herein as a "Representation Date"), as follows:

(i) Requirements for Use of Form S-3; No Stop Orders. The Company meets the requirements for the use of Form S-3 and Rule 415 of the 1933 Act Regulations and has filed or will file with the SEC a Prospectus Supplement relating to the Notes required to be filed pursuant to Rule 424(b) of the 1933 Act Regulations. No stop order suspending the effectiveness of any of the Registration Statements has been issued by the SEC, and no proceedings for the issuance of such a stop order have been instituted or, to the knowledge of the Company, threatened by the SEC.

(ii) Registration Statements and Prospectus. The Registration Statements, at the respective Effective Dates thereof, fully complied, and as of each Representation Date will fully comply, and the Prospectus, at the time of the most recent filing thereof and of any supplement or amendment thereto (including each Pricing Supplement) with the SEC pursuant to Rule 424(b) of the 1933 Act Regulations and as of each Representation Date, as it may then be amended or supplemented, and the Indenture, as of each Representation Date, will fully comply in all material respects with the applicable provisions of the 1933 Act, the 1933 Act Regulations, the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"), and the rules and regulations of the Commission thereunder (the "Trust Indenture Act Regulations"), or pursuant to said rules and regulations did or will be deemed to comply therewith. On the respective Effective Dates thereof and as of each Representation Date, the Registration Statements did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. The Prospectus, at the time of the most recent filing thereof and of any supplement or amendment thereto (including each Pricing Supplement) with the SEC pursuant to Rule 424(b) of the 1933 Act Regulations and as of each Representation Date, will not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The foregoing representations and warranties in this paragraph (ii) shall not apply to statements or


omissions made in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Agents specifically for use in connection with the preparation of the Registration Statements or the Prospectus, as they may be amended or supplemented, or to any statements in or omissions from the statement of eligibility, as it may be amended, under the Trust Indenture Act, of the Trustee under the Indenture (the "Statement of Eligibility"). As used herein, the term "Effective Date" means, with respect to each of the Registration Statements, at any time, the later of (i) the date that such Registration Statement or any post-effective amendment thereto was or is declared effective by the SEC under the 1933 Act and (ii) the date that the Company's Annual Report on Form 10-K for its most recently completed fiscal year is filed with the SEC under the 1934 Act, in each case at such time.

(iii) Incorporated Documents. The Incorporated Documents heretofore filed, when they were filed (or, if any amendment with respect to any such document was filed, when such amendment was filed), conformed in all material respects with the requirements of the 1934 Act and the 1934 Act Regulations, and any further Incorporated Documents so filed will, when they are filed, conform in all material respects with the requirements of the 1934 Act and the 1934 Act Regulations; no such Incorporated Document when it was filed (or, if an amendment with respect to any such document was filed, when such amendment was filed) contained any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; and such further Incorporated Documents, when filed, will not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(iv) Indenture. The Indenture has been duly and validly authorized by all necessary corporate action on the part of the Company, has been duly and validly executed and delivered by the Company, is a legal, valid and binding instrument of the Company enforceable against the Company in accordance with its terms, except as limited by bankruptcy, insolvency, reorganization, fraudulent conveyance or other similar laws affecting creditors' rights and general equitable principles (whether considered in a proceeding in equity or at law), and has been duly qualified under the Trust Indenture Act and no proceedings to suspend such qualification have been instituted or, to the knowledge of the Company, threatened by the SEC. The Indenture conforms in all material respects to all statements relating thereto contained in the Prospectus.

The Notes have been duly authorized by all necessary corporate action on the part of the Company, and, when the terms of the Notes have been established pursuant to the Indenture and when the Notes are authenticated and delivered in accordance with the Indenture against payment therefor, the Notes will constitute the legally, valid and binding obligations of the Company enforceable against the Company in accordance with their terms, except as limited by bankruptcy, insolvency, reorganization, fraudulent conveyance or other similar laws affecting creditors' rights and general equitable principles (whether considered in a proceeding in equity or at law), and will be entitled to the


benefits of the Indenture. The Notes will conform in all material respects to all statements relating thereto contained in the Prospectus.

(b) Additional Certifications. Any certificate signed by any director or officer of the Company and delivered to one or more Agents or to counsel for the Agents in connection with an offering of Notes to one or more Agents as principal or through an Agent as agent shall be deemed a representation and warranty by the Company to such Agent or Agents as to the matters covered thereby on the date of such certificate and at each Representation Date subsequent thereto.

SECTION 3. Purchases as Principal; Solicitations as Agent.

(a) Purchases as Principal. Unless otherwise agreed by an Agent and the Company, Notes shall be purchased by one or more Agents as principal in accordance with terms agreed upon by such Agent or Agents and the Company (which terms, unless otherwise agreed, shall, to the extent applicable, include those terms specified in Exhibit A hereto and be agreed upon orally with written confirmation prepared by such Agent or Agents and mailed or sent by facsimile transmission to the Company). An Agent's commitment to purchase Notes as principal shall be deemed to have been made on the basis of the representations and warranties of the Company herein contained and shall be subject to the terms and conditions herein set forth. Unless the context otherwise requires, references herein to "this Agreement" shall include the applicable agreement of one or more Agents to purchase Notes from the Company as principal. Each purchase of Notes, unless otherwise agreed, shall be at a discount from the principal amount of each such Note equivalent to the applicable commission set forth in Schedule A hereto. The Agents may engage the services of any other broker or dealer in connection with the resale of the Notes purchased by them as principal and may allow all or any portion of the discount received in connection with such purchases from the Company to such brokers and dealers. At the time of each purchase of Notes by one or more Agents as principal, such Agent or Agents shall specify the requirements for the stand-off agreement, officers' certificate, opinions of counsel and comfort letter pursuant to Sections 4(k), 7(b), 7(c) and 7(d) hereof.

(b) Solicitations as Agent. On the basis of the representations and warranties herein contained, but subject to the terms and conditions herein set forth, when agreed by the Company and an Agent, such Agent, as an agent of the Company, will use its reasonable efforts to solicit offers to purchase the Notes upon the terms and conditions set forth in the Prospectus. The Agents are not authorized to appoint sub-agents with respect to Notes sold through them as agent. All Notes sold through an Agent as agent will be sold at 100% of their principal amount unless otherwise agreed to by the Company and such Agent.


The Company reserves the right, in its sole discretion, to suspend solicitation of purchases of the Notes through an Agent, as agent, commencing at any time for any period of time or permanently. As soon as practicable after receipt of instructions from the Company, such Agent will suspend solicitation of purchases from the Company until such time as the Company has advised such Agent that such solicitation may be resumed.

The Company agrees to pay each Agent a commission, in the form of a discount, equal to the applicable percentage of the principal amount of each Note sold by the Company as a result of a solicitation made by such Agent as set forth in Schedule A hereto.

(c) Administrative Procedures. The purchase price, interest rate or formula, maturity date and other terms of the Notes (as applicable) specified in Exhibit A hereto shall be agreed upon by the Company and the applicable Agent or Agents and specified in a Pricing Supplement to be prepared in connection with each sale of Notes. Except as may be otherwise specified in the applicable Pricing Supplement, the Notes will be issued in denominations of $1,000 or any larger amount that is an integral multiple of $1,000. Administrative procedures with respect to the sale of Notes shall be agreed upon from time to time by the Company, the Agents and the Trustee (the "Proce- dures"). The Agents and the Company agree to perform, and the Company agrees to cause the Trustee to agree to perform, their respective duties and obligations specifically provided to be performed by them in the Procedures.

SECTION 4. Covenants of the Company.

(a) Legal Opinions. On the date hereof, the Agents shall have received the following legal opinions, dated as of the date hereof and in form and substance satisfactory to the Agents:

(1) Opinion of Company Counsel. The favorable opinion of O'Melveny & Myers, counsel to the Company, to the effect that:

(i) The Company has been duly incorporated and is validly existing in good standing under the laws of the State of California, with corporate power to own and lease its properties, to carry on its business as described in the Prospectus and to enter into this Agreement and to issue and deliver the Notes as provided therein.

(ii) The statements in the Prospectus under the captions "Description of the Notes" (except under the caption "--Book-Entry Notes") and "Description of Debt Securities" (except under the caption "--Book-Entry Debt Securities"), insofar


as such statements constitute matters of California, New York or federal law applicable to the Company or summaries of the Indenture, fairly present the information required to be included therein by the 1933 Act, the 1933 Act Regulations, the Trust Indenture Act and the Trust Indenture Act Regulations.

(iii) The Notes have been duly authorized by all necessary corporate action on the part of the Company, and, when the terms of the Notes have been established pursuant to the Indenture and upon payment for and delivery of the Notes in accordance with this Agreement and the Indenture, the Notes will constitute the legal, valid and binding obligations of the Company enforceable against the Company in accordance with their terms, except as may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or affecting creditors' rights generally (including, without limitation, fraudulent conveyance laws) and by general principles of equity including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing and the possible unavailability of specific performance or injunctive relief, regardless of whether considered in a proceeding in equity or at law.

(iv) Each of the Registration Statements has been declared effective under the 1933 Act and, to the knowledge of such counsel, no stop order suspending the effectiveness of any of the Registration Statements has been issued or threatened by the SEC.

(v) The execution, delivery and performance of this Agreement have been duly and validly authorized by all necessary corporate action on the part of the Company and this Agreement has been duly executed and delivered by the Company.

(vi) No consent, approval, authorization or order of, or filing with, any federal, California or New York governmental authority is required on the part of the Company for the issuance and sale of the Notes as contemplated by this Agreement, except (i) such as may have been obtained under the 1933 Act, the 1933 Act Regulations, the Trust Indenture Act or the Trust Indenture Act Regulations, (ii) the authorizations of the CPUC referred to in
Section 2(a)(x) of this Agreement which have been obtained, remain in full force and effect and are, to the knowledge of such counsel, not the subject of any pending or threatened application for rehearing or petition for modification, and (iii) such as may be required under state securities or blue sky laws or the by-laws and rules of the National Association of Securities Dealers, Inc. in connection with the purchase and distribution of the Notes.

(vii) The Indenture has been duly authorized by all necessary corporate action on the part of the Company, executed and delivered by the Company and qualified under the Trust Indenture Act and constitutes the legal, valid and binding obligation of the Company enforceable against the Company in accordance with its


terms, except as may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or affecting creditors' rights generally (including, without limitation, fraudulent conveyance laws) and by general principles of equity including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing and the possible unavailability of specific performance or injunctive relief, regardless of whether considered in a proceeding in equity or at law.

(viii) The Company's execution, delivery and performance of this Agreement, the Indenture and the Notes do not violate the Company's Articles of Incorporation, Bylaws or any applicable California, New York or federal law, ordinance, administrative or governmental rule or regulation.

(ix) The Registration Statements, at the respective Effective Dates thereof, and the Prospectus, at the date it was filed with, or transmitted for filing to, the SEC pursuant to Rule 424(b) of the 1933 Act Regulations, appeared on their face to comply in all material respects with the requirements as to form under the 1933 Act and the 1933 Act Regulations in effect at the date of filing, except that such counsel need express no opinion concerning the financial statements and other financial information contained or incorporated by reference therein. The Incorporated Documents, on the respective dates they were filed, appeared on their face to comply in all material respects with the requirements as to form for reports on Form 10-K, Form 10-Q and Form 8-K, as the case may be, under the 1934 Act and the 1934 Act Regulations in effect at the respective dates of their filing, except that such counsel need express no opinion concerning the financial statements and other financial information contained or incorporated by reference therein.

(x) Neither the Company nor any of its subsidiaries is a "holding company" or a "subsidiary company" of a "holding company" or an "affiliate" of a "holding company" or of such a "subsidiary company" within the meaning of the 1935 Act.

(xi) The statements set forth in the Prospectus Supplement under the caption "Certain Tax Considerations," constitute a fair and accurate summary of the matters addressed therein, based upon current law and the assumptions stated or referred to therein.

In connection with such counsel's participation in the preparation of the Registration Statements and the Prospectus (excluding the summary financial information attached to the Form 8-Ks dated February 14, 1996 and May 2, 1996 incorporated by reference therein), such counsel need not independently verify the accuracy, completeness or fairness of the statements contained or incorporated therein, and the limitations inherent in the examination made by such counsel and the knowledge available to it are such that such counsel need not assume any responsibility for such accuracy, completeness or fairness (except as otherwise specifically stated in paragraphs (ii) and (xi) above).


However, on the basis of such counsel's review of the Registration Statements, the Prospectus and the Incorporated Documents and such counsel's participation in conferences in connection with the preparation of the Registration Statements and the Prospectus (excluding the summary financial information attached to the Form 8-Ks dated February 14, 1996 and May 2, 1996 incorporated by reference therein), such counsel does not believe that any of the Registration Statements and the Incorporated Documents, as of the respective Effective Dates thereof, considered as a whole as of such date, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and such counsel does not believe that the Prospectus and the Incorporated Documents, considered as a whole at the time the Prospectus was filed with, or transmitted for filing to, the SEC pursuant to Rule 424(b) of the 1933 Act Regulations and on the date of such opinion (in each case including the Incorporated Documents and considered as whole as of such dates), contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. However, such counsel need not express any opinion or belief as to (x) the financial statements and other financial or statistical data included or incorporated by reference in the Registration Statements or the Prospectus or (y) the Statement of Eligibility.

All the outstanding shares of capital stock of the Subsidiaries have been duly authorized and validly issued, are fully paid and nonassessable, and are owned of record directly by the Company free and clear of any perfected security interest, or, to the best knowledge of such counsel after reasonable inquiry, any other security interest, lien, adverse claim, equity or other encumbrance.

(iii) To the best knowledge of such counsel after due inquiry, neither the Company nor either of the Subsidiaries is in violation of or is in default in the performance of any obligation contained in any bond, debenture, note or any other evidence of indebtedness or in any material agreement, indenture, lease or other instrument to which the Company or either of the Subsidiaries is a


party or by which any of them or any of their respective properties may be bound which violation or default could reasonably be expected to have a Material Adverse Effect.

(iv) To the best knowledge of such counsel, after reasonable inquiry, there are no rights that entitle or will entitle any person to acquire any security of the Company upon the issuance of the Notes by the Company; to the best knowledge of such counsel after due inquiry, there is no holder of any security of the Company or any other person who has the right contractual or otherwise to cause the Company to sell or otherwise issue to them, or to permit them to underwrite the sale of, any securities of the Company as a result of the issuance of the Notes by the Company.

(v) The Company's execution, delivery and performance of this Agreement, the Indenture and the Notes do not (i) violate, breach, or result in a default under, any existing obligation of the Company under any agreement, indenture, lease or other instrument to which the Company is a party or by which it or any of its properties is bound that is an exhibit to the Registration Statements or to any Incorporated Document or any other material agreement, indenture, lease or other instrument known to such counsel after due inquiry,

Section 2(a)(x) of this Agreement which have been obtained, remain in full force and effect and are, to the knowledge of such counsel, not the subject of any pending or threatened application for rehearing or petition for modification, and (iii) such as may be required under state securities or blue sky laws or the by-laws and rules of the National Association of Securities Dealers, Inc. in connection with the purchase and distribution of the Notes.

(vii) To the best knowledge of such counsel after reasonable inquiry, other than as described or contemplated in the Prospectus, there are no legal or governmental proceedings pending or threatened against the Company or either of the Subsidiaries, or to which the Company or either of the Subsidiaries, or any of their property, is subject, which are required to be described in the Registration Statements or Prospectus and are not so described.


In addition, such counsel shall include in his opinion a statement substantially to the effect set forth in the last paragraph of subsection
(a)(1) above.

In rendering their opinions as aforesaid, counsel may rely upon an opinion or opinions, each dated the date hereof, of other counsel retained by them or the Company as to laws of any jurisdiction other than the United States or (x) in the case of O'Melveny & Myers, the States of California and New York and (y) in the case of Robert M. Johnson, Esq., the States of Arizona and Nevada, provided that (1) such reliance is expressly authorized by each opinion so relied upon, (2) a signed copy of each such opinion is delivered to the Agents that states that the Agents may rely thereon and is otherwise in form and substance satisfactory to them and their counsel, and (3) counsel shall state in their opinion that they believe that they and the Agents are justified in relying thereon.

Each time that (i) any of the Registration Statements or the Prospectus shall be amended or supplemented to include additional financial information (other than by an amendment or supplement relating solely to the issuance and/or offering of securities other than the Notes), (ii) there is filed with the SEC any Incorporated Document that contains additional financial information, or (iii) (if required in connection with the purchase of Notes from the Company by one or more Agents as principal) the Company sells Notes to such Agent or Agents as principal, the Company shall cause Arthur Andersen LLP forthwith to furnish to the Agents a letter, dated the date of effectiveness of such amendment, supplement or document with the SEC, or the date of such sale, as the case may be, in form satisfactory to the Agents, of the same tenor as the portions of the letter referred to in clauses (i) and (ii) of Section 5(c) hereof but modified to relate to the Registration Statements and Prospectus as amended and supple- mented to the date of such letter, and of the same general tenor as the portions of the letter referred to in clauses (iii) and (iv) of said Section 5(c) with such changes as may be necessary to reflect changes in the financial statements and other information derived from the accounting records of the Company.

(e) Subsequent Delivery of CPUC Authorizations. Each time that the Company gives to the Agents the written notification required by Section 4(a)(vi) of this Agreement, the Company shall concurrently deliver to the Agents and to counsel for the Agents (i) a certified copy of each such authorization, and (ii) written opinions of O'Melveny & Myers, counsel to the Company, and Robert M. Johnson, Associate General Counsel for the Company, to the effect set forth in paragraph (vi) of Section 5(a)(1) and paragraph (vi) of Section 5(a)(2), respectively, of this Agreement modified to reflect such authorizations.


SECTION 8. Indemnification.

(a) Indemnification of the Agents. The Company will indemnify and hold harmless each Agent, the directors, officers, employees and agents of each Agent and each person, if any, who controls each Agent within the meaning of
Section 15 of the 1933 Act or Section 20 of the 1934 Act from and against any and all losses, claims, liabilities, expenses and damages (including any and all investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted), to which they, or any of them, may become subject under the 1933 Act, the 1934 Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, liabilities, expenses or damages arise out of or are based on any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or the Prospectus or any amendment or supplement to the Registration Statement or the Prospectus or in any Incorporated Documents (when read together with the Prospectus), or the omission or alleged omission to state in such document a material fact required to be stated in it or necessary to make the statements in it not misleading, provided that the Company will not be liable to the extent that such loss, claim, liability, expense or damage arises from the sale of the Notes in the public offering to any person by such Agent and is based on an untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with information relating to such Agent furnished in writing to the Company by such Agent expressly for inclusion in the Registration Statement or the Prospectus, or based upon statements in or omissions from the Statement of Eligibility. This indemnity agreement will be in addition to any liability that the Company might otherwise have.

(b) Indemnification of the Company. Each Agent will indemnify and hold harmless the Company, each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, each director of the Company and each officer of the Company who signed the Registration Statement to the same extent as the foregoing indemnity from the Company to each Agent, but only insofar as losses, claims, liabilities, expenses or damages arise out of or are based on any untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with information relating to such Agent furnished in writing to the Company by such Agent expressly for inclusion in the Registration Statement or the Prospectus. This indemnity will be in addition to any liability that each Agent might otherwise have.

(c) General. Any party that proposes to assert the right to be indemnified under this Section 8 will, promptly after receipt of notice of commencement of any action against such party in respect of which a claim is to be made against an indemnifying party or parties under this Section 8, notify each such indemnifying party of the commencement of such action, enclosing a copy of all papers served, but the omission so to notify such indemnifying party will not relieve it from any liability that it may have to any indemnified party under the foregoing provisions of this Section 8 unless, and only to the extent that, such omission results in the forfeiture of or substantial prejudice to substantive rights or defense by the indemnifying party. If any such action is brought against any indemnified party and it notifies the indemnifying party of its commencement, the indemnifying party will be entitled to participate in and, to the extent that it elects by delivering written notice to the indemnified party promptly after receiving notice of the commencement of the action from the indemnified party, jointly with any other indemnifying party similarly notified, to assume the defense of the action, with counsel satisfactory to the indemnified party, and after


notice from the indemnifying party to the indemnified party of its election to assume the defense, the indemnifying party will not be liable to the indemnified party for any legal or other expenses except as provided below and except for the reasonable costs of investigation subsequently incurred by the indemnified party in connection with the defense. The indemnified party will have the right to employ its own counsel in any such action, but the fees, expenses and other charges of such counsel will be at the expense of such indemnified party unless (i) the employment of counsel by the indemnified party has been authorized in writing by the indemnifying party, (ii) the indemnified party has reasonably concluded (based on advice of counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, (iii) a conflict or potential conflict exists (based on advice of counsel to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party) or (iv) the indemnifying party has not in fact employed counsel to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action, in each of which cases the reasonable fees, disbursements and other charges of counsel will be at the expense of the indemnifying party or parties. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm admitted to practice in such jurisdiction at any one time for all such indemnified party or parties. All such fees, disbursements and other charges will be reimbursed by the indemnifying party promptly as they are incurred. An indemnifying party will not be liable for any settlement of any action or claim effected without its written consent (which consent will not be unreasonably withheld).

SECTION 9. Contribution.

In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in Section 8 of this Agreement is applicable in accordance with its terms but for any reason is held to be unavailable from the Company or the Agents, the Company and the Agents will contribute to the total losses, claims, liabilities, expenses and damages (including any investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted, but after deducting any contribution received by the Company from persons other than the Agents, such as persons who control the Company within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act, officers of the Company who signed the Registration Statement and directors of the Company, who also may be liable for contribution) to which the Company and any one or more of the Agents may be subject in such proportion as shall be appropriate to reflect the relative


benefits received by the Company on the one hand and the Agents on the other. The relative benefits received by the Company on the one hand and the Agents on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) of any Notes received by the Company bear to the total underwriting discounts and commissions received by the Agents, in each case as set forth in the applicable Pricing Supplement. If, but only if, the allocation provided by the foregoing sentence is not permitted by applicable law, the allocation of contribution shall be made in such proportion as is appropriate to reflect not only the relative benefits referred to in the foregoing sentence but also the relative fault of the Company, on the one hand, and the Agents, on the other, with respect to the statements or omissions that resulted in such loss, claim, liability, expense or damage, or action in respect thereof, as well as any other relevant equitable considerations with respect to such offering. Such relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Agents, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Agents agree that it would not be just and equitable if contributions pursuant to this Section 9 were to be determined by pro rata allocation (even if the Agents were treated as one entity for such purpose) or by any other method of allocation which does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, liability, expense or damage, or action in respect thereof, referred to above in this Section 9 shall be deemed to include, for purposes of this Section 9, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 9, no Agent shall be required to contribute any amount in excess of the underwriting discounts and commissions received by it, and no person found guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 9, any person who controls a party to this Agreement within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act Regulations will have the same rights to contribution as that party, and each officer of the Company who signed the Registration Statement will have the same rights to contribution as the Company, subject in each case to the provisions hereof. Any party entitled to contribution, promptly after receipt of notice of commencement of any action against such party in respect of which a claim for contribution may be made under this Section 9, will notify any such party or parties from whom contribution may be sought, but the omission so to notify will not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have under this Section 9. No party will be liable for contribution with respect to any action or claim settled without its written consent (which consent will not be unreasonably withheld). The indemnity and contribution agreements contained in Section 8 of this Agreement and this Section 9 and the representations and warranties of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of the Agents, (ii) acceptance of any of the Notes and payment therefor or (iii) any termination of this Agreement.

SECTION 10. Payment of Expenses.

The Company will pay all expenses incident to the performance of its obligations under this Agreement, including:

(a) The preparation and filing of the Registration Statements and all amendments thereto and the Prospectus and any amendments or supplements thereto;

(b) The preparation, filing and reproduction of this Agreement;


(c) The preparation, printing, issuance and delivery of the Notes, including any fees and expenses relating to the eligibility and issuance of Notes in book-entry form;

(d) The fees and disbursements of the Company's accountants and counsel, of the Trustee and its counsel, and of any calculation agent;

(e) The reasonable fees and disbursements of counsel to the Agents incurred in connection with the establishment of the program relating to the Notes and incurred from time to time in connection with the transactions contemplated hereby;

(f) The qualification of the Notes under state securities laws in accordance with the provisions of Section 4(i) hereof, including filing fees and the reasonable fees and disbursements of counsel for the Agents in connection therewith and in connection with the preparation of any blue sky survey;

(g) The printing and delivery to the Agents in quantities as hereinabove stated of copies of the Registration Statements and any amendments thereto, and of the Prospectus and any amendments or supplements thereto, and the delivery by the Agents of the Prospectus and any amendments or supplements thereto in connection with solicitations or confirmations of sales of the Notes;

(h) The preparation, reproducing and delivery to the Agents of copies of the Indenture and all amendments, supplements and modifications thereto;

(i) Any fees charged by nationally recognized statistical rating organizations for the rating of the Notes;

(j) The fees and expenses incurred in connection with any listing of Notes on a securities exchange;

(k) The fees and expenses incurred with respect to any filing with the National Association of Securities Dealers, Inc.;

(l) Any advertising and other out-of-pocket expenses of the Agents incurred with the approval of the Company; and

(m) The cost of providing any CUSIP or other identification numbers for the Notes.

SECTION 11. Representations, Warranties and Agreements to Survive Delivery.

All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company submitted pursuant hereto or thereto shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of the Agents or any con- trolling person of an Agent, or by or on behalf of the Company, and shall survive each delivery of and payment for any of the Notes.


SECTION 12. Termination.

(a) Termination of this Agreement. This Agreement (excluding any agreement by one or more Agents to purchase Notes from the Company as principal) may be terminated for any reason, at any time by either the Company or an Agent, as to itself, upon the giving of 30 days' written notice of such termination to the other party hereto.

(b) Termination of Agreement to Purchase Notes as Principal. The applicable Agent or Agents may terminate any agreement by such Agent or Agents to purchase Notes from the Company as principal, immediately upon notice to the Company, at any time prior to the Settlement Date relating thereto, if (i) there has been, since the date of such agreement or since the respective dates as of which information is given in the Prospectus, any material adverse change in the condition (financial or other), business, prospects, properties, net worth or results of operations of the Company and its subsidiaries consid- ered as one enterprise, whether or not arising in the ordinary course of business, or (ii) there shall have occurred any material adverse change in the financial markets in the United States or any outbreak or escalation of hostilities or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of such Agent or Agents, impracticable to market the Notes or enforce contracts for the sale of the Notes, or (iii) trading in any securities of the Company has been suspended by the SEC, the New York Stock Exchange or the Pacific Stock Exchange, or if trading generally on either the American Stock Exchange or the New York Stock Exchange or in the over-the- counter market shall have been suspended or limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by either of said exchanges or by such system or by order of the SEC, the National Association of Securities Dealers, Inc. or any other governmental authority, or if a banking moratorium shall have been declared by either Federal or New York authorities, or (iv) the rating assigned by any nationally recognized statistical rating organization to any debt securities of the Company as of the date of such agreement shall have been lowered since that date or if any such rating organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any debt securities of the Company, or (v) there shall have come to the attention of such Agent or Agents any facts that would cause them to believe that the Prospectus, at the time it was required to be delivered to a purchaser of Notes, included any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at the time of such delivery, not misleading. As used in this Section 12(b), the term "Prospectus" means the Prospectus in the form first provided to the applicable Agent or Agents for use in confirming sales of the related Notes.

(c) General. In the event of any such termination, neither party will have any liability to the other party hereto, except that (i) the Agents shall be entitled to any commission earned in accordance with the third paragraph of
Section 3(b) hereof, (ii) if at the time of termination (a) any Agent shall own any Notes purchased by it as principal with the intention of reselling them or (b) an offer to purchase any of the Notes has been accepted by the Company but the time of delivery to the purchaser or his agent of the Note or Notes relating thereto has not occurred, the covenants set forth in Sections 4


and 7 hereof shall remain in effect until such Notes are so resold or deliv- ered, as the case may be, and (iii) the covenant set forth in Section 4(h) hereof, the provisions of Section 10 hereof, the indemnity and contribution agreements set forth in Sections 8 and 9 hereof, and the provisions of Sections 11, 14 and 15 hereof shall remain in effect.

SECTION 13. Notices.

APPENDIX A
SOUTHWEST GAS CORPORATION

ADMINISTRATIVE PROCEDURES

FOR FIXED RATE AND FLOATING RATE MEDIUM-TERM NOTES, SERIES A
DUE NINE MONTHS OR MORE FROM DATE OF ISSUE

(Dated as of December 30, 1996)

Medium-Term Notes, Series A due nine months or more from date of issue (the "Notes") are to be offered on a continuous basis by Southwest Gas Corporation, a California corporation (the "Company"), to or through Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated, Dean Witter Reynolds Inc. and PaineWebber Incorporated (each, an "Agent" and, collectively, the "Agents") pursuant to a Distribution Agreement, dated December 30, 1996 (the "Distribution Agreement"), by and among the Company and the Agents.

Unless otherwise agreed by an Agent and the Company, Notes shall be purchased by the one or more Agents as principal in accordance with terms agreed upon by such Agent or Agents and the Company (which terms, unless otherwise agreed, shall, to the extent applicable, include those terms specified in Exhibit A to the Distribution Agreement, and be agreed upon orally with written confirmation prepared by such Agent or Agents and mailed or sent by facsimile transmission to the Company). If agreed upon by any Agent or Agents and the Company, the Agent or Agents, acting solely as agent or agents for the Company and not as principal, will use reasonable efforts to solicit offers to purchase the Notes. Only those provisions in these Administrative Procedures that are applicable to the particular role to be performed by the related Agent or Agents shall apply to the offer and sale of the relevant Notes.

The Notes will be issued as a series of debt securities under an Indenture, dated as of July 15, 1996, as amended, supplemented or modified from time to time, including by the Second Supplemental Indenture dated as of December 30, 1996 (as so amended, supplemented or modified, the "Indenture"), between the Company and Harris Trust and Savings Bank, as trustee (together with any successor in such capacity, the "Trustee"). The Company has filed Registration Statements (as defined in the Distribution Agreement) with the Securities and Exchange Commission (the "Commission") registering, among other securities, debt securities (which include the Notes). A pricing supplement to the Prospectus (as defined in the Distribution Agreement) setting forth the purchase price, interest rate or formula, maturity date and other terms of any Notes (as applicable) is herein referred to as a "Pricing Supplement".


The Notes will either be issued (a) in book-entry form and represented by one or more fully registered Notes without coupons (each, a "Global Note") delivered to the Trustee, as agent for The Depository Trust Company ("DTC"), and recorded in the book-entry system maintained by DTC, or (b) in certificated form (each, a "Certificated Note") delivered to the investor or other purchaser thereof or a person designated by such investor or other purchaser.

General procedures relating to the issuance of all Notes are set forth in Part I hereof. Additionally, Global Notes will be issued in accordance with the procedures set forth in Part II hereof and Certificated Notes will be issued in accordance with the procedures set forth in Part III hereof. Capitalized terms used but not otherwise defined herein shall have the meanings ascribed thereto in the Indenture or the Notes, as the case may be.

PART I: PROCEDURES OF GENERAL
APPLICABILITY

Date of Issuance/
 Authentication:        Each Note will be dated as of the date of its
                        authentication by the Trustee.  Each Note shall also
                        bear an original issue date (each, an "Original
                        Issue Date").  The Original Issue Date shall remain
                        the same for all Notes subsequently issued upon
                        transfer, exchange or substitution of an original
                        Note regardless of their dates of authentication.

Maturities:             Each Note will mature on a date nine months or more
                        from its Original Issue Date (the "Stated Maturity
                        Date") selected by the investor or other purchaser

Interest Rate Bases
 applicable to
 Floating Rate
 Notes:                 Unless otherwise provided in the applicable Pricing
                        Supplement, Floating Rate Notes will bear interest
                        at a rate or rates determined by reference to the CD
                        Rate, the CMT Rate, the Commercial Paper Rate, the


                        11th District Cost of Funds Rate, the Federal Funds
                        Rate, LIBOR, the Prime Rate, the J.J. Kenny Rate,
                        the Treasury Rate, or such other interest rate basis
                        or formula as may be set forth in the applicable
                        Pricing Supplement, or by reference to two or more
                        such rates, as adjusted by the Spread and/or Spread
                        Multiplier, if any, applicable to such Floating Rate
                        Notes.

Redemption/Repayment:   The Notes will be subject to redemption by the
                        Company in accordance with the terms of the Notes,
                        which will be fixed at the time of sale and set
                        forth in the applicable Pricing Supplement.  If no
                        Initial Redemption Date is indicated with respect to
                        a Note, such Note will not be redeemable prior to
                        its Stated Maturity Date.

                        The Notes will be subject to repayment at the option
                        of the Holders thereof in accordance with the terms
                        of the Notes, which will be fixed at the time of
                        sale and set forth in the applicable Pricing
                        Supplement.  If no optional repayment date is
                        indicated with respect to a Note, such Note will not
                        be repayable at the option of the Holder prior to
                        its Stated Maturity Date.

Calculation of
 Interest:              In case of Fixed Rate Notes, interest (including
                        payments for partial periods) will be calculated and
                        paid on the basis of a 360-day year of twelve 30-day
                        months.

                        The interest rate on each Floating Rate Note (and
                        Floating Rate Notes designated as "Floating Rate/Fixed
                        Rate Notes" or "Inverse Floating Rate Notes") will be
                        calculated by reference to the specified Interest
                        Rate Basis or Bases plus or minus the applicable
                        Spread, if any, and/or multiplied by the applicable
                        Spread Multiplier, if any.

                        Unless otherwise provided in the applicable Pricing
                        Supplement, accrued interest on each Floating Rate
                        Note will be calculated by multiplying its principal
                        amount by an accrued interest factor.  Such accrued
                        interest factor is computed by adding the interest
                        factors calculated for each day in the period for
                        which accrued interest is being calculated.  Unless
                        otherwise provided in the applicable Pricing
                        Supplement, the interest factor (expressed as a
                        decimal calculated to seven decimal places without
                        rounding) for each such day is computed by dividing
                        the interest rate in effect on such day by 360 if

                        the CD Rate, Commercial Paper Rate, 11th District
                        Cost of Funds Rate, Federal Funds Rate, LIBOR or
                        Prime Rate is an applicable Interest Rate Basis, or
                        by the actual number of days in the year if the CMT
                        Rate or Treasury Rate is an applicable Interest
                        Rate Basis, or by 365 days if the J.J. Kenny Rate is
                        an applicable Interest Rate Basis.  Unless otherwise
                        provided in the applicable Pricing Supplement, the
                        interest factor for Notes for which the interest
                        rate is calculated with reference to two or more
                        Interest Rate Bases will be calculated in each
                        period in the same manner as if only the lowest,
                        highest or average of the applicable Interest Rate
                        Bases applied.

Interest:               General.  Each Note will bear interest in accordance
                        with its terms.  Unless otherwise provided in the
                        applicable Pricing Supplement, interest on each Note
                        will accrue from and including the Original Issue
                        Date of such Note for the first interest period or
                        from the most recent Interest Payment Date (as
                        defined below) to which interest has been paid or
                        duly provided for all subsequent interest periods to
                        but excluding the applicable Interest Payment Date
                        or the Stated Maturity Date or date of earlier
                        redemption or repayment, as the case may be (the
                        Stated Maturity Date or date of earlier redemption
                        or repayment is referred to herein as the "Maturity
                        Date" with respect to the principal repayable on
                        such date).

                        If an Interest Payment Date or the Maturity Date
                        with respect to any Fixed Rate Note falls on a day
                        that is not a Business Day (as defined below), the
                        required payment to be made on such day need not be
                        made on such day, but may be made on the next
                        succeeding Business Day with the same force and
                        effect as if made on such day, and no interest shall
                        accrue on such payment for the period from and after
                        such day to the next succeeding Business Day.  If an
                        Interest Payment Date other than the Maturity Date
                        with respect to any Floating Rate Note would
                        otherwise fall on a day that is not a Business Day,
                        such Interest Payment Date will be postponed to the
                        next succeeding Business Day, except that in the
                        case of a Note for which LIBOR is an applicable
                        Interest Rate Basis, if such Business Day falls in
                        the next succeeding calendar month, such Interest
                        Payment Date will be the immediately preceding
                        Business Day.  If the Maturity Date with respect to

                        any Floating Rate Note falls on a day that is not a
                        Business Day, the required payment to be made on
                        such day need not be made on such day, but may be
                        made on the next succeeding Business Day with the
                        same force and effect as if made on such day, and no
                        interest shall accrue on such payment for the period
                        from and after the Maturity Date to the next
                        succeeding Business Day.  Unless otherwise provided
                        in the applicable Pricing Supplement, "Business Day"
                        means any day, other than a Saturday or Sunday, that
                        is neither a legal holiday nor a day on which
                        banking institutions or trust companies are
                        authorized or required by law, regulation or
                        executive order to close in The City of New York or
                        in any Place of Payment with respect to any Note;
                        PROVIDED, HOWEVER, that, with respect to Notes for
                        which LIBOR is an applicable Interest Rate Basis,
                        such day is also a London Banking Day (as defined
                        below).  "London Banking Day" means any day on
                        which dealings in deposits in U.S. dollars are
                        transacted in the London interbank market.

                        Regular Record Dates.  Unless otherwise provided in
                        the applicable Pricing Supplement, the "Regular
                        Record Date" for a Floating Rate Note shall be the
                        date 15 calendar days (whether or not a Business
                        Day) preceding the applicable Interest Payment Date
                        and, for a Fixed Rate Note, shall be March 15 or
                        September 15 (whether or not a Business Day)
                        immediately preceding the applicable Interest
                        Payment Date for such Fixed Rate Notes.

                        Interest Payment Dates.  Interest payments will be
                        made on each Interest Payment Date commencing with
                        the first Interest Payment Date following the
                        Original Issue Date; PROVIDED, HOWEVER, the first
                        payment of interest on any Note originally issued
                        between a Regular Record Date and an Interest
                        Payment Date will occur on the Interest Payment Date
                        following the next succeeding Regular Record Date.

                        Unless otherwise provided in the applicable Pricing
                        Supplement, interest payments on Fixed Rate Notes
                        will be made semiannually in arrears on April 1 and
                        October 1 of each year and on the Maturity Date, while
                        interest payments on Floating Rate Notes will be
                        made as specified in the applicable Pricing
                        Supplement.

                        such Agent acting solely as agent for the Company
                        and not as principal will solicit purchases of the

                        Company's agreement contained in the Distribution
                        Agreement.  Each Agent has agreed to make reasonable
                        efforts to assist the Company in obtaining
                        performance by each purchaser whose offer to

                        in Parts II and III hereof under "Settlement
                        Procedure Timetable" with respect to Global Notes
                        and Certificated Notes, respectively (each such date
                        fixed for settlement is hereinafter referred to as a
                        "Settlement Date").  If procedures A and B of the
                        applicable Settlement Procedures with respect to a
                        particular offer are not completed on or before the
                        time set forth under the applicable "Settlement


                        Procedures Timetable", such offer shall not be
                        settled until the Business Day following the
                        completion of settlement procedures A and B or such
                        later date as the purchaser and the Company shall
                        agree.

                        The foregoing settlement procedures may be modified
                        with respect to any purchase of Notes by an Agent as
                        principal if so agreed by the Company and such
                        Agent.

Procedure for Changing
 Rates or Other
 Variable Terms:        When a decision has been reached to change the
                        interest rate or any other variable term on any
                        Notes being sold by the Company, the Company will
                        promptly advise the Agents and the Trustee by
                        facsimile transmission and the Agents will forthwith
                        suspend solicitation of offers to purchase such
                        Notes.  The Agents will telephone the Company with
                        recommendations as to the changed interest rates or
                        other variable terms.  At such time as the Company
                        notifies the Agents and the Trustee of the new
                        interest rates or other variable terms, the Agents
                        may resume solicitation of offers to purchase such
                        Notes.  Until such time, only "indications of
                        interest" may be recorded.  Immediately after
                        acceptance by the Company of an offer to purchase
                        Notes at a new interest rate or new variable term,
                        the Company, the Offering Agent and the Trustee
                        shall follow the procedures set forth under the
                        applicable "Settlement Procedures".

Suspension of
 Solicitation;
 Amendment or
 Supplement:            The Company may instruct the Agents to suspend
                        solicitation of offers to purchase Notes at any
                        time.  Upon receipt of such instructions, the
                        Agents will forthwith suspend solicitation of offers
                        to purchase from the Company until such time as the
                        Company has advised the Agents that solicitation of
                        offers to purchase may be resumed.  If the Company
                        decides to amend or supplement the Registration
                        Statements or the Prospectus (other than to
                        establish or change interest rates or formulas,
                        maturities, prices or other similar variable terms
                        with respect to the Notes), it will promptly advise
                        the Agents and will furnish the Agents and their

                        supplement.  Copies of such amendment or supplement
                        will be delivered or mailed to the Agents, their
                        counsel and the Trustee in quantities which such

                        offers to purchase from the Company is suspended
                        (other than to  establish or change interest rates
                        or formulas, maturities, prices or other similar

                        shall be any offers to purchase Notes that have been
                        accepted by the Company that have not been settled,
                        the Company will promptly advise the Offering Agent
                        and the Trustee whether such offers may be settled
                        and whether copies of the Prospectus as theretofore
                        amended and/or supplemented as in effect at the time
                        of the suspension may be delivered in connection
                        with the settlement of such offers.  The Company
                        will have the sole responsibility for such decision
                        and for any arrangements that may be made in the
                        event that the Company determines that such offers
                        may not be settled or that copies of such Prospectus

                        Prospectus and the applicable Pricing Supplement.

                        Owners of beneficial interests in Global Notes will
                        be entitled to physical delivery of Certificated
                        Notes equal in principal amount to their respective
                        beneficial interests only upon certain limited
                        circumstances described in the Prospectus.


Identification:         The Company has arranged with the CUSIP Service
                        Bureau of Standard & Poor's (the "CUSIP Service
                        Bureau") for the reservation of one series of CUSIP
                        numbers, which series consists of approximately
                        900 CUSIP numbers which have been reserved for and
                        relating to Global Notes and the Company has
                        delivered to each of the Trustee and DTC such list
                        of such CUSIP numbers.  The Company will assign
                        CUSIP numbers to Global Notes as described below
                        under Settlement Procedure B.  DTC will notify the
                        CUSIP Service Bureau periodically of the CUSIP
                        numbers that the Company has assigned to Global
                        Notes.  The Trustee will notify the Company at any
                        time when fewer than 100 of the reserved CUSIP
                        numbers remain unassigned to Global Notes, and, if
                        it deems necessary, the Company will reserve and
                        obtain additional CUSIP numbers for assignment to
                        Global Notes.  Upon obtaining such additional CUSIP
                        numbers, the Company will deliver a list of such
                        additional numbers to the Trustee and DTC.  Notes
                        issued in book-entry form in excess of $200,000,000
                        aggregate principal amount and otherwise required to
                        be represented by the same Global Note will instead
                        be represented by two or more Global Notes which
                        shall all be assigned the same CUSIP number.

Registration:           Unless otherwise specified by DTC, each Global Note
                        will be registered in the name of Cede & Co., as
                        nominee for DTC, on the register maintained by the
                        Trustee under the Indenture.  The beneficial owner
                        of a Note issued in book-entry form (i.e., an owner
                        of a beneficial interest in a Global Note) (or one
                        or more indirect participants in DTC designated by
                        such owner) will designate one or more participants
                        in DTC (with respect to such Note issued in
                        book-entry form, the "Participants") to act as agent
                        for such beneficial owner in connection with the
                        book-entry system maintained by DTC, and DTC will
                        record in book-entry form, in accordance with
                        instructions provided by such Participants, a credit
                        balance with respect to such Note issued in
                        book-entry form in the account of such Participants.
                        The ownership interest of such beneficial owner in
                        such Note issued in book-entry form will be recorded
                        through the records of such Participants or through
                        the separate records of such Participants and one or
                        more indirect participants in DTC.


Transfers:              Transfers of beneficial ownership interests in a
                        Global Note will be accomplished by book entries
                        made by DTC and, in turn, by Participants (and in
                        certain cases, one or more indirect participants in
                        DTC) acting on behalf of beneficial transferors and
                        transferees of such Global Note.

Exchanges:              The Trustee may deliver to DTC and the CUSIP Service
                        Bureau at any time a written notice specifying (a)
                        the CUSIP numbers of two or more Global Notes
                        outstanding on such date that represent Global Notes
                        having the same Fixed Rate Terms or Floating Rate
                        Terms, as the case may be (other than Original Issue
                        Dates), and for which interest has been paid to the
                        same date; (b) a date, occurring at least 30 days
                        after such written notice is delivered and at least
                        30 days before the next Interest Payment Date for
                        the related Notes issued in book-entry form, on
                        which such Global Notes shall be exchanged for a
                        single replacement Global Note; and (c) a new CUSIP
                        number, obtained from the Company, to be assigned to
                        such replacement Global Note.  Upon receipt of such
                        a notice, DTC will send to its Participants
                        (including the Trustee) a written reorganization
                        notice to the effect that such exchange will occur
                        on such date.  Prior to the specified exchange date,
                        the Trustee will deliver to the CUSIP Service Bureau
                        written notice setting forth such exchange date and
                        the new CUSIP number and stating that, as of such
                        exchange date, the CUSIP numbers of the Global Notes
                        to be exchanged will no longer be valid.  On the
                        specified exchange date, the Trustee will exchange
                        such Global Notes for a single Global Note bearing
                        the new CUSIP number and the CUSIP numbers of the
                        exchanged Notes will, in accordance with CUSIP
                        Service Bureau procedures, be canceled and not
                        immediately reassigned.  Notwithstanding the
                        foregoing, if the Global Notes to be exchanged
                        exceed $200,000,000 in aggregate principal amount,
                        one replacement Note will be authenticated and
                        issued to represent each $200,000,000 in aggregate
                        principal amount of the exchanged Global Notes and
                        an additional Global Note or Notes will be
                        authenticated and issued to represent any remaining
                        principal amount of such Global Notes (See
                        "Denominations" below).


Denominations:          Unless otherwise provided in the applicable Pricing
                        Supplement, Notes issued in book-entry form will be
                        issued in denominations of $1,000 and integral
                        multiples thereof.  Global Notes will not be
                        denominated in excess of $200,000,000 aggregate
                        principal amount.  If one or more Notes are issued
                        in book-entry form in excess of $200,000,000
                        aggregate principal amount and would, but for the
                        preceding sentence, be represented by a single
                        Global Note, then one Global Note will be issued to
                        represent each $200,000,000 in aggregate principal
                        amount of such Notes issued in book-entry form and
                        an additional Global Note or Notes will be issued to
                        represent any remaining aggregate principal amount
                        of such Note or Notes issued in book-entry form.  In
                        such a case, each of the Global Notes representing
                        Notes issued in book-entry form shall be assigned
                        the same CUSIP number.

Payments of Principal
  and Interest:         Payments of Interest Only.  Promptly after each
                        Regular Record Date, the Trustee will deliver to the
                        Company and DTC a written notice specifying by CUSIP
                        number the amount of interest to be paid on each
                        Global Note on the following Interest Payment Date
                        (other than an Interest Payment Date coinciding with
                        the Maturity Date) and the total of such amounts.
                        DTC will confirm the amount payable on each Global
                        Note on such Interest Payment Date by reference to
                        the daily bond reports published by Standard &
                        Poor's.  On such Interest Payment Date, the Company
                        will pay to the Trustee in immediately available
                        funds an amount sufficient to pay the interest then
                        due and owing on the Global Notes, and upon receipt
                        of such funds from the Company, the Trustee in turn
                        will pay to DTC such total amount of interest due on
                        such Global Notes (other than on the Maturity Date),
                        at the times and in the manner set forth below under
                        "Manner of Payment".  The Trustee shall make payment
                        of that amount of interest due and owing on any
                        Global Notes that Participants have elected to
                        receive in foreign or composite currencies directly
                        to such Participants.

                        Notice of Interest Rates.  Promptly after each
                        Interest Determination Date or Calculation Date, as
                        the case may be, for Floating Rate Notes issued in
                        book-entry form, the Trustee will notify each of
                        Moody's Investors Service, Inc. and Standard &
                        Poor's of the interest rates determined as of such
                        Interest Determination Date.


Payments at Maturity. On or about the first Business Day of each month, the Trustee will deliver to the Company and DTC a written list of principal, premium, if any, and interest to be paid on each Global Note maturing or otherwise becoming due in the following month. The Trustee, the Company and DTC will confirm the amounts of such principal, premium, if any, and interest payments with respect to each such Global Note on or about the fifth Business Day preceding the Maturity Date of such Global Note. On the Maturity Date, the Company will pay to the Trustee in immediately available funds an amount sufficient to make the required payments, and upon receipt of such funds the Trustee in turn will pay to DTC the principal amount of Global Notes, together with premium, if any, and interest due on the Maturity Date, at the times and in the manner set forth below under "Manner of Payment". Promptly after payment to DTC of the principal, premium, if any, and interest due on the Maturity Date of such Global Note, the Trustee will cancel such Global Note and deliver it to the Company with an appropriate debit advice. On the first Business Day of each month, the Trustee will deliver to the Company a written statement indicating the total principal amount of outstanding Global Notes as of the close of business on the immediately preceding Business Day.

Manner of Payment. The total amount of any principal, premium, if any, and interest due on Global Notes on any Interest Payment Date or the Maturity Date, as the case may be, shall be paid by the Company to the Trustee in funds available for use by the Trustee no later than 10:00 a.m., New York City time, on such date. The Company will make such payment on such Global Notes to an account specified by the Trustee. Upon receipt of such funds, the Trustee will pay by separate wire transfer (using Fedwire message entry instructions in a form previously specified by DTC) to an account at the Federal Reserve Bank of New York previously specified by DTC, in funds available for immediate use by DTC, each payment of principal, premium, if any, and interest due on Global Notes on such date. Thereafter on such date, DTC will pay, in accordance with its SDFS operating procedures then in effect, such amounts in funds available for immediate use to the respective Participants in whose names the beneficial interests in such Global Notes are


                        recorded in the book-entry system maintained by DTC.
                        Neither the Company nor the Trustee shall have any
                        responsibility or liability for the payment by DTC
                        of the principal of, or premium, if any, or interest
                        on, the Global Notes.

                        Withholding Taxes.  The amount of any taxes required
                        under applicable law to be withheld from any
                        interest payment on a Global Note will be determined
                        and withheld by the Participant, indirect
                        participant in DTC or other Person responsible for
                        forwarding payments and materials directly to the
                        beneficial owner of such Global Note.

Settlement Procedure H is subject to extension in accordance with any extension of Fedwire closing deadlines and in the other events specified in the SDFS operating procedures in effect on the Settlement Date.

If settlement of a Note issued in book-entry form is rescheduled or canceled, the Trustee will deliver to DTC, through DTC's Participant Terminal System, a cancellation message to such effect by no later than


                        5:00 p.m., New York City time, on the Business Day
                        immediately preceding the scheduled Settlement Date.

Failure to Settle:      If the Trustee fails to enter an SDFS deliver order
                        with respect to a Note issued in book-entry form
                        pursuant to Settlement Procedure F, the Trustee may
                        deliver to DTC, through DTC's Participant Terminal
                        System, as soon as practicable a withdrawal message
                        instructing DTC to debit such Note to the
                        participant account of the Trustee maintained at
                        DTC.  DTC will process the withdrawal message,
                        provided that such participant account contains a
                        principal amount of the Global Note representing
                        such Note that is at least equal to the principal
                        amount to be debited.  If withdrawal messages are
                        processed with respect to all the Notes represented
                        by a Global Note, the Trustee will mark such Global
                        Note "canceled", make appropriate entries in its
                        records and send certification of destruction of
                        such canceled Global Note to the Company.  The CUSIP
                        number assigned to such Global Note shall, in
                        accordance with CUSIP Service Bureau procedures, be
                        canceled and not immediately reassigned.  If
                        withdrawal messages are processed with respect to a
                        portion of the Notes represented by a Global Note,
                        the Trustee will exchange such Global Note for two
                        Global Notes, one of which shall represent the
                        Global Notes for which withdrawal messages are
                        processed and shall be canceled immediately after
                        issuance and the other of which shall represent the
                        other Notes previously represented by the
                        surrendered Global Note and shall bear the CUSIP
                        number of the surrendered Global Note.

                        In the case of any Note in book-entry form sold
                        through the Offering Agent, as agent, if the
                        purchase price for any such Note is not timely paid
                        to the Participants with respect thereto by the
                        beneficial investor or other purchaser thereof (or a
                        person, including an indirect participant in DTC,
                        acting on behalf of such investor or other
                        purchaser), such Participants and, in turn, the
                        related Offering Agent may enter SDFS deliver orders
                        through DTC's Participant Terminal System reversing
                        the orders entered pursuant to Settlement Procedures
                        F and G, respectively.  Thereafter, the Trustee will

                        deliver the withdrawal message and take the related
                        actions described in the preceding paragraph.  If
                        such failure shall have occurred for any reason
                        other than default by the applicable Offering Agent
                        to perform its obligations hereunder or under the
                        Distribution Agreement, the Company will reimburse
                        such Offering Agent on an equitable basis for its
                        reasonable loss of the use of funds during the
                        period when the funds were credited to the account
                        of the Company.

                        Notwithstanding the foregoing, upon any failure to
                        settle with respect to a Note in book-entry form,
                        DTC may take any actions in accordance with its SDFS
                        operating procedures then in effect.  In the event
                        of a failure to settle with respect to a Note that
                        was to have been represented by a Global Note also
                        representing other Notes, the Trustee will provide,
                        in accordance with Settlement Procedure D, for the
                        authentication and issuance of a Global Note
                        representing such remaining Notes and will make
                        appropriate entries in its records.

                  PART III:  PROCEDURES FOR CERTIFICATED NOTES


Denominations:          Unless otherwise provided in the applicable Pricing
                        Supplement, the Certificated Notes will be issued in
                        denominations of $1,000 and integral multiples
                        thereof.

                        principal of, premium, if any, and interest on, each
                        Certificated Note on the Maturity Date in
                        immediately available funds.  All interest payments
                        on a Certificated Note, other than interest due on
                        the Maturity Date, will be made by check mailed to
                        the address of the person entitled thereto as such
                        address shall appear in the Security Register;
                        PROVIDED, HOWEVER, that Holders of $10,000,000 or
                        more in aggregate principal amount of Certificated

This Security is one of the series designated on the face hereof. The Securities of this series may be issued from time to time at varying maturities, interest rates and other terms as may be designated with respect to a Security.

The interest rate borne by this Security shall be determined as follows:

(i) Unless this Security is designated as a "Floating Rate/Fixed Rate Note," an "Inverse Floating Rate Note" or as having an Addendum


attached, this Security shall be designated as a "Regular Floating Rate Note" and, except as described below or as specified on the face hereof, bear interest at the rate determined by reference to the Interest Rate Basis or Bases specified on the face hereof (a) plus or minus the Spread, if any, specified on the face hereof and/or (b) multiplied by the Spread Multiplier, if any, specified on the face hereof. Commencing on the first Interest Reset Date (as defined below), the rate at which interest on this Security shall be payable shall be reset as of each Interest Reset Date; provided, however, that the interest rate in effect for the period from the Original Issue Date to the first Interest Reset Date shall be the Initial Interest Rate specified on the face hereof.

(ii) If this Security is designated as a "Floating Rate/Fixed Rate Note," then, except as described below or as specified on the face hereof, this Security shall bear interest at the rate determined by reference to the Interest Rate Basis or Bases specified on the face hereof (a) plus or minus the Spread, if any, specified on the face hereof and/or (b) multiplied by the Spread Multiplier, if any, specified on the face hereof. Commencing on the first Interest Reset Date, the rate at which interest on this Security shall be payable shall be reset as of each Interest Reset Date; provided, however, that the interest rate in effect for the period from the Original Issue Date to the first Interest Reset Date shall be the Initial Interest Rate specified on the face hereof and the interest rate in effect commencing on the Fixed Rate Commencement Date specified on the face hereof to Stated Maturity shall be the Fixed Interest Rate, if such rate is specified on the face hereof or, if no such Fixed Interest Rate is so specified, the interest rate in effect hereon on the day immediately preceding the Fixed Rate Commencement Date.

(iii) If this Security is designated as an "Inverse Floating Rate Note," then, except as described below or as specified on the face hereof, this Security shall bear interest equal to the Fixed Interest Rate specified on the face hereof minus the rate determined by reference to the Interest Rate Basis or Bases specified on the face hereof (a) plus or minus the Spread, if any, specified on the face hereof and/or
(b) multiplied by the Spread Multiplier, if any, specified on the face hereof; provided, however, that, unless otherwise specified on the face hereof, the interest rate hereon shall not be less than zero during any Interest Rate Reset Period (as defined below). Commencing on the first Interest Reset Date, the rate at which interest on this Security is payable shall be reset as of each Interest Reset Date; provided, however, that the interest rate in effect for the period from the Original Issue


Date to the first Interest Reset Date shall be the Initial Interest Rate specified on the face hereof.

Notwithstanding the foregoing, if this Security is designated as having an Addendum attached as specified on the face hereof, this Security shall bear interest in accordance with the terms described in such Addendum and as specified on the face hereof.

Except as set forth above or as specified on the face hereof, the interest rate in effect on each day shall be (i) if such day is an Interest Reset Date, the interest rate determined as of the Interest Determination Date (as defined below) immediately preceding such Interest Reset Date or (ii) if such day is not an Interest Reset Date, the interest rate determined as of the Interest Determination Date immediately preceding the most recent Interest Reset Date.

Unless otherwise specified on the face hereof:

(1) The "Interest Reset Date" shall be, if the interest rate specified on the face hereof resets (i) daily, each Business Day;
(ii) weekly, the Wednesday of each week (except with respect to the Treasury Rate which shall reset on the Tuesday of each week, except as described below); (iii) monthly, the third Wednesday of each month (except with respect to the 11th District Cost of Funds Rate which shall reset on the first calendar day of the month); (iv) quarterly, the third Wednesday of March, June, September and December of each year;
(v) semiannually, the third Wednesday of the two months specified on the face hereof; and (vi) annually, the third Wednesday of the month specified on the face hereof. If any Interest Reset Date would otherwise be a day that is not a Business Day, such Interest Reset Date shall be postponed to the next succeeding day that is a Business Day, unless LIBOR is an applicable Interest Rate Basis, in which case, if such Business Day falls in the next succeeding calendar month, such Interest Reset Date shall be the immediately preceding Business Day.

(2) The "Interest Determination Date" with respect to this Security shall be: (i) if the applicable Interest Rate Basis is the CD Rate, the CMT Rate, the Commercial Paper Rate, the Federal Funds Rate, the J.J. Kenny Rate or the Prime Rate, the second Business Day immediately preceding the applicable Interest Reset Date; (ii) if the applicable Interest Rate Basis is the 11th District Cost of Funds Rate, the last Business Day of the month immediately preceding the applicable Interest Reset Date on which the Federal Home Loan Bank of San Francisco publishes the Index (as defined below); (iii) if the applicable Interest Rate Basis is LIBOR, the second London Banking Day (as defined below) immediately preceding the applicable Interest Reset Date; and (iv) if the applicable


Interest Rate Basis is the Treasury Rate, the day of the week in which the applicable Interest Reset Date falls on which day Treasury Bills (as defined below) are normally auctioned; provided, however, that if an auction is held on the Friday of the week preceding the applicable Interest Reset Date, the Interest Determination Date will be such preceding Friday; and provided, further, that if an auction falls on the applicable Interest Reset Date, then the Interest Reset Date will instead be the first Business Day following such auction. If the interest rate on this Security is determined by reference to two or more Interest Rate Bases, the Interest Determination Date shall be the second Business Day prior to the applicable Interest Reset Date for this Security on which each Interest Rate Basis is determinable. Each Interest Rate Basis will be determined on such date, and the applicable interest rate will take effect on the applicable Interest Reset Date.

(3) The "Calculation Date," if applicable, pertaining to any Interest Determination Date will be the earlier of (i) the tenth calendar day after such Interest Determination Date, or, if such day is not a Business Day, the next succeeding Business Day or (ii) the Business Day immediately preceding the applicable Interest Payment Date or Stated Maturity, as the case may be.

Unless otherwise specified on the face hereof, the interest rate with respect to each Interest Rate Basis shall be determined in accordance with the following provisions:

Determination of CD Rate

If the Interest Rate Basis with respect to this Security is the CD Rate, such rate shall be determined by the Calculation Agent appointed as agent by and of the Company to calculate the rates of interest applicable to securities including this Security ("Calculation Agent") in accordance with the following provisions:

"CD Rate" means, with respect to any Interest Determination Date, the rate on such date for negotiable certificates of deposit having the Index Maturity specified on the face hereof as published by the Board of Governors of the Federal Reserve System in "Statistical Release H.15(519), Selected Interest Rates" or any successor publication ("H.15(519)") under the heading "CDs (Secondary Market)," or, if not published by 3:00 p.m., New York City time, on the related Calculation Date, the rate on such Interest Determination Date for negotiable certificates of deposit of the Index Maturity specified on the face hereof as published by the Federal Reserve Bank of New York in its daily statistical release "Composite 3:30 p.m. Quotations for U.S. Government Securities" or any successor publication ("Composite Quotations") under the heading "Certificates of Deposit." If such rate is not yet published in either H.15(519) or Composite Quotations by 3:00 p.m., New York City time, on


the related Calculation Date, then the CD Rate on such Interest Determination Date will be calculated by the Calculation Agent and will be the arithmetic mean of the secondary market offered rates as of 10:00 a.m., New York City time, on such Interest Determination Date, of three leading nonbank dealers in negotiable United States dollar certificates of deposit in The City of New York selected by the Calculation Agent for negotiable United States certificates of deposit of major United States money market banks for negotiable United States certificates of deposit with a remaining maturity closest to the Index Maturity specified on the face hereon; provided, however, that if the dealers so selected by the Calculation Agent are not quoting as mentioned in this sentence, the CD Rate determined as of such Interest Determination Date will be the CD Rate in effect on such Interest Determination Date.

Determination of CMT Rate

If the Interest Rate Basis with respect to this Security is the CMT Rate, such rate shall be determined by the Calculation Agent in accordance with the following provisions:

"CMT Rate" means, with respect to any Interest Determination Date, the rate displayed on the Designated CMT Telerate Page (as defined below) under the caption " . . . Treasury Constant Maturities . . . Federal Reserve Board Release H.15 . . . Monday's Approximately 3:45 p.m.," under the column for the Designated CMT Maturity Index (as defined below) for (i) if the Designated CMT Telerate Page is 7055, the rate on such Interest Determination Date and (ii) if the Designated CMT Telerate Page is 7052, the week, or the month, as applicable, ended immediately preceding the week in which the related Interest Determination Date occurs. If such rate is no longer displayed on the relevant page, or if not displayed by 3:00 p.m., New York City time, on the related Calculation Date, then the CMT Rate for such Interest Determination Date will be such treasury constant maturity rate for the Designated CMT Maturity Index as published in the relevant H.15(519). If such rate is no longer published, or if not published by 3:00 p.m., New York City time, on the related Calculation Date, then the CMT Rate for such Interest Determination Date will be such treasury constant maturity rate for the Designated CMT Maturity Index (or other United States Treasury rate for the Designated CMT Maturity Index) for the Interest Determination Date with respect to such Interest Reset Date as may then be published by either the Board of Governors of the Federal Reserve System or the United States Department of the Treasury that the Calculation Agent determines to be comparable to the rate formerly displayed on the Designated CMT Telerate Page and published in the relevant H.15(519). If such information is not provided by 3:00 p.m., New York City time, on the related Calculation Date, then the CMT Rate for the Interest Determination Date will be calculated by the Calculation Agent and will be a yield to maturity, based on the arithmetic


mean of the secondary market closing offer side prices as of approximately 3:30 p.m., New York City time, on the Interest Determination Date reported, according to their written records, by three leading primary United States government securities dealers (each, a "Reference Dealer") in The City of New York selected by the Calculation Agent (from five such Reference Dealers selected by the Calculation Agent and eliminating the highest quotation (or, in the event of equality, one of the highest) and the lowest quotation (or, in the event of equality, one of the lowest), for the most recently issued direct noncallable fixed rate obligations of the United States ("Treasury Notes") with an original maturity of approximately the Designated CMT Maturity Index and a remaining term to maturity of not less than such Designated CMT Maturity Index minus one year. If the Calculation Agent cannot obtain three such Treasury Note quotations, the CMT Rate for such Interest Determination Date will be calculated by the Calculation Agent and will be a yield to maturity based on the arithmetic mean of the secondary market offer side prices as of approximately 3:30 p.m., New York City time, on the Interest Determination Date of three Reference Dealers in The City of New York (from five such Reference Dealers selected by the Calculation Agent and eliminating the highest quotation (or, in the event of equality, one of the highest) and the lowest quotation (or, in the event of equality, one of the lowest)), for Treasury Notes with an original maturity of the number of years that is the next highest to the Designated CMT Maturity Index and a remaining term to maturity closest to the Designated CMT Maturity Index and in an amount of at least $100 million. If three or four (and not five) of such Reference Dealers are quoting as described above, then the CMT Rate will be based on the arithmetic mean of the offer prices obtained and neither the highest nor the lowest of such quotes will be eliminated; provided, however, that if fewer than three Reference Dealers selected by the Calculation Agent are quoting as described herein, the CMT Rate will be the CMT Rate in effect on such Interest Determination Date. If two Treasury Notes with an original maturity as described in the third preceding sentence have remaining terms to maturity equally close to the Designated CMT Maturity Index, the quotes for the Treasury Note with the shorter remaining term to maturity will be used.

"Designated CMT Telerate Page" means the display on the Dow Jones Telerate Service on the page specified on the face hereof (or any other page as may replace such page on that service) for the purpose of displaying Treasury Constant Maturities as reported in H.15(519). If no such page is specified on the face hereof, the Designated CMT Telerate Page shall be 7052, for the most recent week.

"Designated CMT Maturity Index" means the original period to maturity of the Treasury Notes (either 1, 2, 3, 5, 7, 10, 20 or 30 years) specified on the face hereof with respect to which the CMT Rate will be calculated. If no such maturity is specified on the face hereof, the Designated CMT Maturity Index shall be 2 years.


Determination of Commercial Paper Rate

If the Interest Rate Basis with respect to this Security is the Commercial Paper Rate, such rate shall be determined by the Calculation Agent in accordance with the following provisions:

"Commercial Paper Rate" means, with respect to any Interest Determination Date, the Money Market Yield (as defined below) on such date of the rate for commercial paper having the Index Maturity specified on the face hereof as published in H.15(519) under the heading "Commercial Paper." In the event that such rate is not published by 3:00 p.m., New York City time, on the related Calculation Date then the Commercial Paper Rate shall be the Money Market Yield on such Interest Determination Date of the rate for commercial paper having the Index Maturity specified on the face hereof as published in Composite Quotations under the heading "Commercial Paper" (with an Index Maturity of one month or three months being deemed to be equivalent to an Index Maturity of 30 days or 90 days, respectively). If by 3:00 p.m., New York City time, on the related Calculation Date such rate is not yet published in H.15(519) or Composite Quotations, then the Commercial Paper Rate on such Interest Determination Date shall be calculated by the Calculation Agent and shall be the Money Market Yield of the arithmetic mean of the offered rates at approximately 11:00 a.m., New York City time, on such Interest Determination Date of three leading dealers of commercial paper in The City of New York (selected by the Calculation Agent in its discretion) for commercial paper having the Index Maturity specified on the face hereof placed for an industrial issuer whose bond rating is "Aa," or the equivalent, from a nationally recognized rating agency; provided, however, that if the dealers selected as aforesaid by the Calculation Agent are not quoting as mentioned in this sentence, the Commercial Paper Rate will be the Commercial Paper Rate in effect on such Interest Determination Date.

"Money Market Yield" means a yield (expressed as a percentage rounded to the nearest one-hundredth of a percent, with five one-thousandths of a percent rounded upwards) calculated in accordance with the following formula:

D X 360

Money Market Yield = ----------------- X 100
360 - (D X M)

where "D" refers to the applicable per annum rate for commercial paper quoted on a bank discount basis and expressed as a decimal and "M" refers to the actual number of days in the interest period for which interest is being calculated.

Determination of 11th District Cost of Funds Rate

If the Interest Rate Basis with respect to this Security is the 11th District Cost of Funds Rate, such rate shall be determined by the Calculation


Agent in accordance with the following provisions:

"11th District Cost of Funds Rate" means, with respect to any Interest Determination Date, the rate equal to the monthly weighted average cost of funds for the calendar month immediately preceding the month in which such Interest Determination Date falls, as set forth under the caption "11th District" on Telerate Page 7058 as of 11:00 a.m., San Francisco time, on such Interest Determination Date. If such rate does not appear on Telerate Page 7058 on any related Interest Determination Date, the 11th District Cost of Funds Rate for such Interest Determination Date shall be the monthly weighted average cost of funds paid by member institutions of the 11th Federal Home Loan Bank District that was most recently announced (the "Index") by the Federal Home Loan Bank of San Francisco as such cost of funds for the calendar month immediately preceding the date of such announcement. If the Federal Home Loan Bank of San Francisco fails to announce such rate for the calendar month immediately preceding such Interest Determination Date, then the 11th District Cost of Funds Rate determined as of such Interest Determination Date will be the 11th District Cost of Funds Rate in effect on such Interest Determination Date.

Determination of Federal Funds Rate

If the Interest Rate Basis with respect to this Security is the Federal Funds Rate, such rate shall be determined by the Calculation Agent in accordance with the following provisions:

"Federal Funds Rate" means, with respect to any Interest Determination Date, the rate on such date for federal funds as published in H.15(519) under the heading "Federal Funds (Effective)" or, if not published by 3:00 p.m., New York City time, on the related Calculation Date, the rate on such Interest Determination Date as published in Composite Quotations under the column "Effective Rate" under the heading "Federal Funds." If by 3:00 p.m., New York City time, on the related Calculation Date such rate is not published in either H.15(519) or Composite Quotations, then the Federal Funds Rate on such Interest Determination Date will be calculated by the Calculation Agent and will be the arithmetic mean of the rates for the last transaction in overnight United States dollar federal funds arranged by three leading brokers of federal funds transactions in The City of New York selected by the Calculation Agent prior to 9:00 a.m., New York City time, on such Interest Determination Date; provided, however, that if the brokers so selected by the Calculation Agent are not quoting as mentioned in this sentence, the Federal Funds Rate determined as of such Interest Determination Date will be the Federal Funds Rate in effect on such Interest Determination Date.


Determination of LIBOR

If the Interest Rate Basis with respect to this Security is LIBOR, such rate shall be determined by the Calculation Agent in accordance with the following provisions:

(i) With respect to an Interest Determination Date, LIBOR will be, as specified on the face hereof, either: (a) the arithmetic mean of the offered rates (unless the Reuters Screen LIBO Page by its terms provides only for a single rate in which case the single rate shall be used) for deposits in U.S. dollars having the Index Maturity specified on the face hereof, commencing on the second London Banking Day immediately following that Interest Determination Date, that appear (or, if only a single rate is required as aforesaid, appears) on the Reuters Screen LIBO Page as of 11:00 a.m., London time, on that Interest Determination Date, if at least two such offered rates appear on the Reuters Screen LIBO Page ("LIBOR Reuters"), or (b) the rate for deposits in U.S. dollars having the Index Maturity specified on the face hereof, commencing on the second London Banking Day immediately following that Interest Determination Date, that appears on the Telerate Page 3750 as of 11:00 a.m., London time, on that Interest Determination Date ("LIBOR Telerate"). "Reuters Screen LIBO Page" means the display designated as page "LIBO" on the Reuters Monitor Money Rates Service (or such other page as may replace the LIBO page on that service for the purpose of displaying London interbank offered rates of major banks). "Telerate Page 3750" means the display designated as page "3750" on the Telerate Service (or such other page as may replace the 3750 page on that service or such other service or services as may be nominated by the British Bankers' Association for the purpose of displaying London interbank offered rates for U.S. dollar deposits). If neither LIBOR Reuters nor LIBOR Telerate is specified on the face hereof, LIBOR will be determined as if LIBOR Telerate had been specified. If fewer than two offered rates appear on the Reuters Screen LIBO Page, in the case where (a) above applies, or if no rate appears on the Telerate Page 3750, in the case where (b) above applies, as applicable, LIBOR in respect of that Interest Determination Date will be determined as if the parties had specified the rate described in (ii) below.

(ii) With respect to an Interest Determination Date on which fewer than two offered rates appear on the Reuters Screen LIBO Page, as specified in
(i)(a) above, or on which no rate appears on Telerate Page 3750, as specified in (i)(b) above, as applicable, LIBOR will be determined on the basis of the rates at which deposits in U.S. dollars having the Index Maturity specified on the face hereof are offered at approximately 11:00 a.m., London time, on that Interest Determination Date by four major banks in the London interbank market selected by the Calculation Agent ("Reference Banks") to prime banks in the London interbank market commencing on the second London Banking Day immediately following that Interest Determination Date and in a principal


amount that is representative for a single transaction in such market at such time. The Calculation Agent will request the principal London office of each of the Reference Banks to provide a quotation of its rate. If at least two such quotations are provided, LIBOR in respect of that Interest Determination Date will be the arithmetic mean of such quotations. If fewer than two quotations are provided, LIBOR in respect of that Interest Determination Date will be the arithmetic mean of the rates quoted at approximately 11:00 a.m., New York City time, on that Interest Determination Date by three major banks in The City of New York selected by the Calculation Agent for the loans in U.S. dollars to leading European banks having the Index Maturity specified on the face hereof commencing on the second London Banking Day immediately following that Interest Determination Date and in a principal amount that is representative for a single transaction in such market at such time; provided, however, that if the banks selected as aforesaid by the Calculation Agent are not quoting as mentioned in this sentence, LIBOR with respect to such Interest Determination Date will be the rate of LIBOR in effect on such date.

"London Banking Day" means any day on which dealings in deposits in U.S. dollars are transacted in the London interbank market.

Determination of Prime Rate

If the Interest Rate Basis with respect to this Security is the Prime Rate, such rate shall be determined by the Calculation Agent in accordance with the following provisions:

"Prime Rate" means, with respect to any Interest Determination Date, the rate on such date as such rate is published in H.15(519) under the heading "Bank Prime Loan." If such rate is not published prior to 3:00 p.m., New York City time, on the related Calculation Date, then the Prime Rate shall be the arithmetic mean of the rates of interest publicly announced by each bank that appears on the Reuters Screen US PRIME 1 Page (as defined below) as such bank's prime rate or base lending rate as in effect for such Interest Determination Date. If fewer than four such rates but more than one such rate appear on the Reuters Screen US PRIME 1 Page for such Interest Determination Date, the Prime Rate shall be the arithmetic mean of the prime rates quoted on the basis of the actual number of days in the year divided by a 360-day year as of the close of business on such Interest Determination Date by four major money center banks in The City of New York selected by the Calculation Agent. If fewer than four such rates appear on the Reuters Screen US PRIME 1, the Prime Rate for such Interest Determination Date will be calculated by the Calculation Agent and will be the arithmetic mean of four prime rates quoted on the basis of the actual number of days in the year divided by a 360-day year as of the close of business on such Interest Determination Date furnished in the City of New York on such Interest Determination Date by the major money center banks, if any, that have provided such quotations and by a reasonable number of substitute banks or trust companies organized and doing


business under the laws of the United States, or any state thereof, having total equity capital of at least U.S. $500 million and being subject to supervision or examination by a Federal or state authority, selected by the Calculation Agent to provide such rates; provided, however, that if the Prime Rate is not published in H.15(519) and the banks or trust companies selected as aforesaid are not quoting as mentioned in this sentence, the Prime Rate determined as of such Interest Determination Date will be the Prime Rate in effect on such Interest Determination Date.

"Reuters Screen US PRIME 1" means the display designated as page "USPRIME1" on the Reuters Monitor Money Rates Service (or such other page as may replace the USPRIME1 page on that service for the purpose of displaying prime rates or base lending rates of major United States banks).

Determination of Treasury Rate

If the Interest Rate Basis with respect to this Security is the Treasury Rate, such rate shall be determined by the Calculation Agent in accordance with the following provisions:

"Treasury Rate" means, with respect to an Interest Determination Date, the rate applicable to the most recent auction of direct obligations of the United States ("Treasury Bills") having the Index Maturity specified on the face hereof as published in H.15(519) under the heading "U.S. Government Securities--Treasury bills--Auction Average (Investment)" or, if not so published by 3:00 p.m., New York City time, on the related Calculation Date pertaining to such Interest Determination Date, the auction average rate (expressed as a bond equivalent on the basis of a year of 365 or 366 days, as applicable, and applied on a daily basis) as otherwise announced by the United States Department of the Treasury. In the event that the results of the auction of Treasury Bills having the Index Maturity specified on the face hereof are not published or reported as provided above by 3:00 p.m., New York City time, on such Calculation Date or if no such auction is held on such Interest Determination Date, then the Treasury Rate shall be calculated by the Calculation Agent and shall be a yield to maturity (expressed as a bond equivalent on the basis of a year of 365 or 366 days, as applicable, and applied on a daily basis) of the arithmetic mean of the secondary market bid rates, as of approximately 3:30 p.m., New York City time, on such Interest Determination Date, of three leading primary United States government securities dealers selected by the Calculation Agent for the issue of Treasury Bills with a remaining maturity closest to the Index Maturity specified on the face hereof; provided, however, that if the dealers selected as aforesaid by the Calculation Agent are not quoting as mentioned in this sentence, the Treasury Rate will be the Treasury Rate in effect on such Interest Determination Date.


Determination of J.J. Kenny Rate

If the Interest Rate Basis with respect to this Security is the J.J. Kenny Rate, such rate shall be determined by the Calculation Agent in accordance with the following provisions:

"J.J. Kenny Rate" means with respect to an Interest Determination Date, the high grade weekly index made available by Kenny Information Systems to the Calculation Agent for 30-day yield evaluations at par of bonds, the interest on which is exempt from Federal income taxation under the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code"), of not less than five high grade component issuers selected by Kenny, including, without limitation, issuers of general obligation bonds, but excluding any bonds on which the interest is subject to a minimum tax or similar tax under the Internal Revenue Code unless all tax-exempt bonds are subject to such tax. In the event Kenny ceases to make available such Weekly Index, a successor indexing agent will be selected by the Calculation Agent, such index to reflect the prevailing rate for bonds rated in the highest short-term rating category by Moody's Investors Service, Inc. and Standard & Poor's in respect of issuers most closely resembling the high grade component issuers selected by Kenny for its Weekly Index, the interest on which is (i) variable on a weekly basis, (ii) exempt from Federal income taxation under the Internal Revenue Code and (iii) not subject to a minimum tax or similar tax under the Internal Revenue Code unless all tax-exempt bonds are subject to such tax. If such successor indexing agent is not available, the J.J. Kenny Rate for such Interest Reset Period will be 67% of the rate determined as if the Treasury Rate option had been originally selected.

Notwithstanding the foregoing, the interest rate hereon shall not be greater than the Maximum Interest Rate, if any, or less than the Minimum Interest Rate, if any, shown on the face hereof. The Calculation Agent shall calculate the interest rate on this Security in accordance with the foregoing on each Interest Determination Date.

The interest rate on this Security will in no event be higher than the maximum rate permitted by New York or California law as the same may be modified by the United States law of general applicability.

The Calculation Agent will, upon the request of the Holder of this Security, provide to such Holder the interest rate hereon then in effect and, if different, the interest rate which will become effective as of the next applicable Interest Reset Date.

If any Interest Payment Date specified on the face hereof would otherwise be a day that is not a Business Day, the Interest Payment Date shall be postponed to the next day that is a Business Day, except that if (i) the rate of interest on this Security shall be determined in accordance with the


provisions of the heading "Determination of LIBOR" above, and (ii) such Business Day is in the next succeeding calendar month, such Interest Payment Date shall be the immediately preceding Business Day. "Business Day" means
(i) any day that is not a Saturday or Sunday and that is not a day on which banking institutions or trust companies are generally authorized or obligated by law to close, and (ii) if any Security has LIBOR as the applicable Interest Rate Basis, is also a London Banking Day.

Interest payments for this Security will include interest accrued from and including the date of issue or from and including the last date in respect of which interest has been paid, as the case may be, to, but excluding, the Interest Payment Date or Stated Maturity, as the case may be. Accrued interest hereon from the Original Issue Date or from the last date to which interest hereon has been paid, as the case may be, shall be an amount calculated by multiplying the face amount hereof by an accrued interest factor. Such accrued interest factor shall be computed by adding the interest factor calculated for each day from the Original Issue Date or from the last date to which interest shall have been paid, as the case may be, to the date for which accrued interest is being calculated. Unless otherwise specified on the face hereof, the interest factor for each such day shall be computed by dividing the interest rate (expressed as a decimal calculated to seven decimals without rounding) applicable to such day by 360, in case the Interest Rate Basis of this Security is the Commercial Paper Rate, LIBOR the CD Rate, the Prime Rate, the Federal Funds Rate and the 11th District Cost of Funds Rate, or by the actual number of days in the year in the case the Interest Rate Basis of this Security is the Treasury Rate or the CMT Rate, or 365 days in the case of the J.J. Kenny Rate. Unless otherwise specified on the face hereof, the interest factor for which the interest rate is calculated with reference to one or more Interest Rate Bases will be calculated in each period in the same manner as if only the applicable Interest Rate Basis specified on the face hereof applied.

On each Optional Reset Date, if any, specified on the face hereof, the Company has the option to reset the Spread and the Spread Multiplier. If no date or dates for such reset are set forth on the face hereof, this Security will not be subject to such reset. The Company may exercise such option by notifying the Trustee of such exercise at least 45 but not more than 60 days prior to an Optional Reset Date. Not later than 40 days prior to such Optional Reset Date, the Trustee will mail to the Holder hereof a notice (the "Reset Notice"), first class, postage prepaid. The Reset Notice will indicate whether the Company has elected to reset the Spread or Spread Multiplier and if so, (i) such new Spread or Spread Multiplier, as the case may be; and (ii) the provisions, if any, for redemption during the period from such Optional Reset Date to the next Optional Reset Date or, if there is no such next Optional Reset Date, to Stated Maturity (each such period a "Subsequent


Interest Period"), including the date or dates on which or the period or periods during which and the price or prices at which such redemption may occur during such Subsequent Interest Period.

Notwithstanding the foregoing, the Company may, at its option, revoke the Spread or Spread Multiplier as provided for in the Reset Notice, and establish a Spread or Spread Multiplier that is higher (or lower if this Security is designated an Inverse Floating Rate Note) than the Spread or Spread Multiplier provided for in the relevant Reset Notice for the Subsequent Interest Period commencing on such Optional Reset Date, by causing the Trustee to mail, not later than 20 days prior to an Optional Reset Date, a notice of such new Spread or Spread Multiplier to the Holder hereof. Such notice will be irrevocable. The Company must notify the Trustee of its intentions to revoke such Reset Notice at least 25 days prior to such Optional Reset Date. If the Spread or Spread Multiplier hereof is reset on an Optional Reset Date and the Holder hereof has not tendered this Security for repayment (or has validly revoked any such tender) pursuant to the next succeeding paragraph, such Holder will bear such new Spread or Spread Multiplier for the Subsequent Interest Period.

If the Company elects to reset the Spread or Spread Multiplier as described above, the Holder hereof will have the option to elect repayment hereof by the Company on any Optional Reset Date at a price equal to the aggregate principal amount hereof outstanding on, plus any interest accrued to, such Optional Reset Date. In order to exercise such option, the Holder hereof must follow the procedures set forth below for optional repayment, except that (i) the period for delivery of this Security or notification to the Trustee will be at least 25 but not more than 35 days prior to such Optional Reset Date and (ii) a Holder who has tendered for repayment pursuant to a Reset Notice may, by written notice to the Trustee, revoke any such tender until the close of business on the tenth day prior to such Optional Reset Date.

Unless otherwise indicated on the face of this Security, this Security may not be redeemed prior to Stated Maturity. If so indicated on the face of this Security, this Security may be redeemed, at the option of the Company, on any date on or after the date set forth on the face hereof, either in whole or from time to time in part at redemption prices declining from a specified premium, if any, to par, together with interest accrued and unpaid thereon to the date of redemption. Notice of redemption shall be mailed to the Holders of the Securities designated for redemption at their addresses as the same shall appear in the Security Register not less than 30 and not more than 60 days prior to the date of redemption, subject to all the conditions and provisions of the Indenture. In the event of any redemption, the Company will not be required to (i) issue, register the transfer of, or exchange any Security during a period beginning at the opening of business 15 days before any selection of Securities to be redeemed and ending at the close of business


on the date of mailing of the relevant notice of redemption or (ii) register the transfer or exchange of any Security, or any portion thereof, called for redemption, except the unredeemed portion of any Security being redeemed in part. Only a new Security or Securities for the amount of the unredeemed portion hereof shall be issued in the name of the Holder upon the cancellation hereof.

If so provided on the face of this Security, the Security will be subject to repayment at the option of the Holder on the date or dates so indicated on the face hereof. If no date or dates for such repayment are set forth on the face hereof, this Security will not be repayable at the option of the Holder prior to Stated Maturity. On an optional repayment date, if any, this Security will be repayable in whole or in part in increments of $1,000 at the option of the Holder at redemption prices declining from a specified premium, if any, to par, together with interest thereon payable to the date of repayment, if the "Option to Elect Repayment," duly completed and received by the Company in accordance with the terms of this Security, is received by the Company not more than 60 nor less than 30 days prior to the date or dates of repayment set forth on the face hereof. In the event of repayment of this Security in part only, a new Security for the unrepaid portion hereof shall be issued in the name of the Holder hereof upon the surrender hereof.

In certain circumstances described in the Indenture, the Company's obligations in respect of the Securities or in respect of certain covenants made for the benefit of the Securities may be discharged prior to payment upon the deposit with the Trustee of cash and/or U.S. Government Obligations in the required amount and upon compliance with certain conditions and other provisions of the Indenture.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of the series may be declared due and payable in the manner and with the effect provided in the Indenture.

Unless otherwise specified on the face hereof, if (i) this Security is issued with original issue discount (as defined in the Internal Revenue Code of 1986, as amended) and (ii) the principal hereof is declared to be due and payable immediately, the amount of principal due and payable with respect hereto shall be limited to the Principal Amount hereof multiplied by the sum of the Issue Price hereof (expressed as a percentage of the Principal Amount hereof) plus the original issue discount amortized from the Original Issue Date to the date of declaration, which amortization shall be computed in accordance with generally accepted bond yield computation principles in effect on the date of declaration.

The Indenture contains provisions permitting the Company and the Trustee, with the consent of the Holders of not less than a majority in


aggregate principal amount of the Notes of each series affected at the time outstanding, as defined in the Indenture, to execute supplemental indentures for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or of modifying in any manner the rights of the Holders of the Notes, provided, however, that no such supplemental indenture shall (i) extend the fixed maturity of any Notes of any series, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon, without the consent of the Holder of each Note so affected, or (ii) reduce the aforesaid percentage of Notes, the Holders of which are required to consent to any such supplemental indenture, without the consent of the Holders of each Note then outstanding and affected thereby. The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the Notes of any series at the time outstanding affected thereby, on behalf of all of the Holders of the Notes of such series, to waive any past default in the performance of any of the covenants contained in the Indenture, or established pursuant to the Indenture with respect to such series, and its consequences, except a default in the payment of the principal of or interest on any of the Notes of such series. Any such consent or waiver by the registered Holder of this Note (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future Holders and owners of this Note and of any Note issued in exchange herefor or in place hereof (whether by registration of transfer or otherwise), irrespective of whether or not any notation of such consent or waiver is made upon this Note.

In certain limited circumstances, the Indenture also permits the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holder, at any time by the Company and the Trustee, without notice to or the consent of the Holders.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Security at the times, places and rate, and in the coin or currency, herein prescribed. However, the Indenture limits Holder's rights to enforce the Indenture and this Security.

As provided in the Indenture and subject to certain limitations set forth therein, the transfer of this Security is registrable in the Securities Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and interest on this Security are payable, duly endorsed by or accompanied by a written instrument of transfer in form satisfactory to the Company and the Securities Registrar duly executed by the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this


series, of authorized denominations, of like aggregate principal amount and bearing interest at the same rate or pursuant to the same formula, having the same date of issuance, redemption provisions, if any, Stated Maturity and other terms will be issued to the designated transferee or transferees. The Securities of this series are issuable only in registered form without coupons in denominations of $1,000 and any integral multiples thereof. As provided in the Indenture and subject to certain limitations set forth therein, Securities of this series are exchangeable for other Securities of this series of a different authorized denomination and like principal amount and bearing the same date of issuance, redemption provisions, if any, Stated Maturity and other terms. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue and none of the Company, the Trustee or any such agent shall be affected by notice to the contrary.

No recourse shall be had for the payment of principal of or the interest on this Security, or any claim based hereon or on the Indenture, against any incorporator, shareholder, officer or director, past, present or future, as such, of the Company or of any predecessor or successor Corporation, under any rule of law, statute, or constitution or by the enforcement of any assessment or otherwise, all such liability being released by the Holder by the acceptance of this Security and being likewise waived and released by the terms of this Indenture.

All percentages resulting from any calculation on this Security will be rounded to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards, and all dollar amounts used in or resulting from such calculation on this Security will be rounded to the nearest cent (with one-half cent being rounded upwards).

THE INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED

IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

As Trustee

Authorized Officer

SOUTHWEST GAS CORPORATION
MEDIUM-TERM NOTES, SERIES A
(FIXED RATE)

This Security is one of a duly authorized issue of Medium-Term Notes, Series A of the Company (herein called the "Securities"), issued and to be issued under an Indenture dated as of July 15, 1996, as amended by the First Supplemental Indenture dated as of August 1, 1996 and Second Supplemental Indenture dated as of December 30, 1996, (herein called the "Indenture") between the Company and Harris Trust and Savings Bank, as trustee (herein called the "Trustee", which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Securities of this series may be issued from time to time at varying maturities, interest rates and other terms as may be designated with respect to a Security.


Interest payments for this Security will include interest accrued to but excluding the Interest Payment Dates. Interest payments for this Security shall be computed and paid on the basis of a 360-day year of twelve 30-day months. If any Interest Payment Date specified on the face hereof would otherwise be a day that is not a Business Day, the Interest Payment Date shall be postponed to the next day that is a Business Day and without any interest or other payment in respect of such delay. "Business Day" means any day that is not a Saturday or Sunday and that is not a day on which banking institutions or trust companies are generally authorized or obligated to close.

Unless otherwise indicated on the face of this Security, this Security may not be redeemed prior to Stated Maturity. If so indicated on the face of this Security, this Security may be redeemed, at the option of the Company, on any date on or after the date set forth on the face hereof, either in whole or from time to time in part at redemption prices declining from a specified premium, if any, to par, together with interest accrued and unpaid thereon to the date of redemption. Notice of redemption shall be mailed to the Holders of the Securities designated for redemption at their addresses as the same shall appear in the Security Register not less than 30 and not more than 60 days prior to the date of redemption, subject to all the conditions and provisions of the Indenture. In the event of any redemption, the Company will not be required to (i) issue, register the transfer of, or exchange any Security during a period beginning at the opening of business 15 days before any selection of Securities to be redeemed and ending at the close of business on the date of mailing of the relevant notice of redemption or (ii) register the transfer or exchange of any Security, or any portion thereof, called for redemption, except the unredeemed portion of any Security being redeemed in part. Only a new Security or Securities for the amount of the unredeemed portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof.

If so provided on the face of this Security, the Security will be subject to repayment at the option of the Holder on the date or dates so indicated on the face hereof. If no date or dates for such repayment are set forth on the face hereof, this Security will not be repayable at the option of the Holder prior to Stated Maturity. On an optional repayment date, if any, this Security will be repayable in whole or in part in increments of $1,000 at the option of the Holder at redemption prices declining from a specified premium, if any, to par, together with interest thereon payable to the date of repayment, if the "Option to Elect Repayment," duly completed and received by the Company in accordance with the terms of this Security, is received by the Company not more than 60 nor less than 30 days prior to the date or dates of


repayment set forth on the face hereof. In the event of repayment of this Security in part only, a new Security for the unrepaid portion hereof shall be issued in the name of the Holder hereof upon the surrender hereof.

In certain circumstances described in the Indenture, the Company's obligation in respect of the Securities or in respect of certain covenants made for the benefit of the Securities may be discharged prior to payment upon the deposit with the Trustee of cash and/or U.S. Government Obligations in the required amount and upon compliance with certain conditions and other provisions of the Indenture.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

Unless otherwise specified on the face hereof, if (i) this Security is issued with original issue discount (as defined in the Internal Revenue Code of 1986, as amended) and (ii) the principal hereof is declared to be due and payable immediately, the amount of principal due and payable with respect hereto shall be limited to the Principal Amount hereof multiplied by the sum of the Issue Price hereof (expressed as a percentage of the Principal Amount hereof) plus the original issue discount amortized from the Original Issue Date to the date of declaration, which amortization shall be computed in accordance with generally accepted bond yield computation principles in effect on the date of declaration.

The Indenture contains provisions permitting the Company and the Trustee, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes of each series affected at the time outstanding, as defined in the Indenture, to execute supplemental indentures for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or of modifying in any manner the rights of the Holders of the Notes, provided, however, that no such supplemental indenture shall (i) extend the fixed maturity of any Notes of any series, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon, without the consent of the Holder of each Note so affected, or (ii) reduce the aforesaid percentage of Notes, the Holders of which are required to consent to any such supplemental indenture, without the consent of the Holders of each Note then outstanding and affected thereby. The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the Notes of any series at the time outstanding affected thereby, on behalf of all of the Holders of the Notes of such series, to waive any past default in the performance of any of the covenants contained in the Indenture, or


established pursuant to the Indenture with respect to such series, and its consequences, except a default in the payment of the principal of or interest on any of the Notes of such series. Any such consent or waiver by the registered Holder of this Note (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future Holders and owners of this Note and of any Note issued in exchange herefor or in place hereof (whether by registration of transfer or otherwise), irrespective of whether or not any notation of such consent or waiver is made upon this Note.

In certain limited circumstances, the Indenture also permits the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders, at any time by the Company and the Trustee, without notice to or the consent of the Holders.

No reference herein to the Indenture and no provisions of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Security at the times, places and rate, and in the coin or currency, herein prescribed. However, the Indenture limits Holder's rights to enforce the Indenture and this Security.

As provided in the Indenture and subject to certain limitations set forth therein, the transfer of this Security is registrable in the Securities Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and interest on this Security are payable, duly endorsed by or accompanied by a written instrument of transfer in form satisfactory to the Company and the Securities Registrar duly executed by the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations, of like aggregate principal amount and bearing interest at the same rate or pursuant to the same formula, having the same date of issuance, redemption provisions, if any, Stated Maturity and other terms will be issued to the designated transferee or transferees. The Securities of this series are issuable only in registered form without coupons in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations set forth therein, Securities of this series are exchangeable for other Securities of this series of a different authorized denomination and principal amount and bearing interest at the same rate or pursuant to the same formula, having the same date of issuance, redemption provisions, if any, Stated Maturity and other terms. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.


Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and none of the Company, the Trustee or any such agent shall be affected by notice to the contrary.

No recourse shall be had for the payment of the principal of or the interest on this Security, or for any claim based hereon or on the Indenture, against any incorporator, shareholder, officer or director, past, present or future, as such, of the Company or of any predecessor or successor Corporation, under any rule of law, statute or constitution or by the enforcement of any assessment or otherwise, all such liability being released by the Holder by the acceptance of this Security and being likewise waived and released by the terms of the Indenture.

HARRIS TRUST AND SAVINGS BANK

THIS AGREEMENT is made as of December 30, 1996, between SOUTHWEST GAS CORPORATION (the "Company"), and HARRIS TRUST AND SAVINGS BANK (the

WHEREAS, the Company proposes to issue and sell on a continuous basis its Medium-Term Notes, Series A (the "Notes") pursuant to the terms and conditions of a Distribution Agreement (the "Distribution Agreement") dated December 30, 1996 by and among the Company and Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated, PaineWebber Incorporated and Dean Witter Reynolds Inc.

(b) In no event shall the interest rate be less than the minimum interest rate, if any, or higher than the maximum interest rate, if any, designated in the applicable pricing supplement.

(c) The Calculation Agent shall calculate the amount of interest payable on each Floating Rate Note in the manner and at the times set forth in such Note.
(d) As soon as practicable after each Calculation Date, the Calculation Agent will cause to be forwarded to the Company and the Trustee information regarding the interest rates, the interest periods, the amount of interest for each interest period and the relevant Interest Payment Dates. The Calculation Agent will, upon the request of any holder of any Floating Rate Note, provide the interest rate which will become effective as a result of a determination made with respect to the most recent Interest Determination Date with respect to such Note.

SECTION 3. Status of Calculation Agent. Any acts taken by the Calculation Agent under this Agreement or in connection with any Floating Rate Notes, including, specifically, without limitation, the calculation of any interest rate for a Floating Rate Note, shall be deemed to have been taken by the Calculation Agent solely in its capacity as agent of the Company and shall not create or imply any obligation to, or any agency or trust relationship with any of the owners or holders of the Floating Rate Notes.


SECTION 4. Fees and Expenses. The Calculation Agent shall be entitled to such compensation for its services under this Agreement as may be agreed upon with the Company, and the Company shall pay such compensation and shall reimburse the Calculation Agent for all reasonable expenses, disbursements and advances incurred or made by the Calculation Agent in connection with the services rendered by it under this Agreement, including reasonable counsel fees.

SECTION 5. Rights and Liabilities of Calculation Agent. The Calculation Agent shall incur no liability for, or in respect of, any action taken or omitted to be taken, or suffered by it in reliance upon any Floating Rate Note, written instruction, notice, request, direction, certificate, consent, report, affidavit, statement, order or other instrument, paper, document or communication reasonably believed by it in good faith to be genuine. Any order, certificate, affidavit, instruction, notice, request, direction, statement or other comments from the Company or given by it and sent, delivered or directed to the Calculation Agent under, pursuant to or as permitted by any provision of this Agreement shall be sufficient for purposes of this Agreement if such comment is in writing and signed by an officer of the Company. The Calculation Agent may consult with counsel satisfactory to it and the advice of such counsel shall constitute full and complete authorization and protection of the Calculation Agent with respect to any action taken, omitted to be taken, or suffered by it hereunder in good faith and in accordance with and in reliance upon the advice of such counsel. Neither the Calculation Agent nor its officers or employees shall be liable to the Company or any other party for any act or omission hereunder, except in the case of gross negligence or willful misconduct and, in any event, to the extent permitted by law, it is agreed that the liability of the Calculation Agent and its officers and employees hereunder for damages, regardless of the form of the action, shall not exceed the fees payable to the Calculation Agent hereunder for a period of six months, and that this shall be the exclusive remedy for any damages hereunder. No party shall be liable for any default resulting from force majeure, which shall be deemed to include any circumstance beyond the reasonable control of the party affected. No action, regardless of form, arising out of or pertaining to the role of the Calculation Agent hereunder may be brought by any party hereto or beneficiary hereof more than twelve (12) months after the cause of action has accrued.

SECTION 6. Duties of Calculation Agent. The Calculation Agent shall be obligated only to perform such duties as are specifically set forth herein and no other duties or obligations on the part of the Calculation Agent


in its capacity as such, shall be implied by this Agreement. Neither the Calculation Agent nor its officers and directors guarantee the correctness or completeness of any data or other information furnished hereunder.

SECTION 7. Termination, Resignation or Removal of Calculation Agent. The Calculation Agent may at any time terminate this Agreement by giving written notice to the Company and the Trustee specifying the date on which its desired resignation shall become effective, provided that such notice shall be given no less than ninety (90) days prior to said effective date unless the Calculation Agent, Company and Trustee otherwise agree in writing. The Company may terminate this Agreement at any time by giving written notice to the Calculation Agent and specifying the date when the termination shall become effective; provided that such effective date of the Company's termination shall be at least twenty (20) days after the date of notice and shall not be less than forty-five (45) days before the Interest Payment Date on any Floating Rate Note that shall be the final Interest Payment Date with respect to which such Calculation Agent shall serve as the Calculation Agent. No termination by either the Calculation Agent or the Company shall become effective prior to the date of the appointment by the Company of a successor Calculation Agent and the acceptance of such appointment by such successor Calculation Agent as provided in Section 8 hereof. Upon termination by either party pursuant to the provisions of this Section, the Calculation Agent shall be entitled to the payment of any compensation owed to it by the Company hereunder and to the reimbursement of all reasonable expenses incurred in connection with the services rendered by it hereunder, as provided by
Section 4 hereof. The provisions of Sections 9 and 13 hereof shall remain in effect following termination by either party.

Any successor Calculation Agent appointed by the Company and approved by the Trustee following termination of this Agreement pursuant to the provisions of
Section 7 hereof, shall execute and deliver to the original Calculation Agent, the Company and the Trustee an instrument accepting such appointment. Thereupon, such successor Calculation Agent shall, without any further act, deed or conveyance, become vested with all the authority, rights, powers, trusts, immunities, duties and obligations of the Calculation Agent and with like effect as if originally named as Calculation Agent hereunder, and the original Calculation Agent shall thereupon be obligated to transfer and deliver such relevant records or copies thereof maintained by the Calculation Agent in connection with the performance of its obligations hereunder.

Re: Up to $150,000,000 Aggregate Principal Amount of Medium-Term Notes, Series A of Southwest Gas Corporation (the "Company")

Ladies and Gentlemen:

We have acted as special counsel in connection with the issuance and sale by the Company of an aggregate of up to $150,000,000 principal amount of the Company's Medium-Term Notes, Series A (the "Notes") pursuant to that certain Distribution Agreement dated December 30, 1996 (the "Agreement") among the Company, Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated, Dean Witter Reynolds Inc. and Painewebber Incorporated. The Notes are to be issued pursuant to an Indenture dated as of July 15, 1996 (the "Original Indenture") between the Company and Harris Trust and Savings Bank, as Trustee (the "Trustee"), as supplemented and amended by the First Supplemental Indenture dated as of August 1, 1996 (the "First Supplement") and the Second Supplemental Indenture dated as of December 30, 1996 (the "Second Supplement" and together with the First Supplement and the Original Indenture, the "Indenture").

On the basis of our consideration of such questions of law as we have deemed relevant in the circumstances, we are of the opinion, subject to the assumptions and limitations set forth herein, that the Notes have been duly authorized by all necessary corporate action on the part of the Company and, when the final terms of a particular Note and of its issuance and sale have been duly established in conformity with the Indenture and when such


Page 2 - Southwest Gas Corporation - December 30, 1996

Note has been duly executed, authenticated and issued in accordance with the provisions of the Indenture and upon payment for and delivery of the Notes in accordance with the terms of the Agreement and the Indenture, will constitute the legally valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except as may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or affecting creditors' rights generally (including, without limitation, fraudulent conveyance laws), and except that the enforceability of the Notes is subject to the effect of general principles of equity, including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing and the possible unavailability of specific performance or injunctive relief, regardless of whether considered in a proceeding in equity or at law.

We have, with your approval, assumed that the certificates for the Notes will conform to the forms thereof examined by us, that the signatures on all documents examined by us are genuine, that all items submitted as originals are authentic, and that all items submitted as copies conform to the originals, assumptions which we have not independently verified.

We consent to the incorporation of this opinion in the Company's current Report on Form 8-K, event date December 30, 1996.

Respectfully submitted,

/s/ O'MELVENY & MYERS LLP
