Ladies and Gentlemen:

        From time to time Southwest Gas Corporation, a California corporation
(the "Company"), proposes to enter into one or more Pricing Agreements (each a
"Pricing Agreement") in the form of Annex I hereto, with such additions and
deletions as the parties thereto may determine, and, subject to the terms and
conditions stated herein and therein, to issue and sell to the firms named in
Schedule I to the applicable Pricing Agreement (such firms constituting the
"Underwriters" with respect to such Pricing Agreement and the securities
specified therein) certain of its debt securities (the "Securities") specified
in Schedule II to such Pricing Agreement (with respect to such Pricing
Agreement, the "Designated Securities").

        The terms and rights of any particular issuance of Designated Securities
shall be as specified in the Pricing Agreement relating thereto and in or
pursuant to the indenture (the "Indenture") identified in such Pricing
Agreement.

        1. Particular sales of Designated Securities may be made from time to
time to the Underwriters of such Securities, for whom the firm or firms
designated as representatives of the Underwriters of such Securities in the
Pricing Agreement relating thereto will act as representatives (the
"Representatives"). The term "Representatives" also refers to a single firm
acting as sole representative of the Underwriters and to an Underwriter or
Underwriters who act without any firm being designated as its or their
representatives. This Underwriting Agreement shall not be construed as an
obligation of the Company to sell any of the Securities or as an obligation of
any of the Underwriters to purchase the Securities. The obligation of the
Company to issue and sell any of the Securities and the obligation of any of the
Underwriters to purchase any of the Securities shall be evidenced by the Pricing
Agreement with respect to the Designated Securities specified therein. Each
Pricing Agreement shall specify the aggregate principal amount of such
Designated Securities, the initial public offering price of such

   2

Designated Securities, the purchase price to the Underwriters of such Designated
Securities, the names of the Underwriters of such Designated Securities, the
names of the Representatives of such Underwriters and the principal amount of
such Designated Securities to be purchased by each Underwriter and shall set
forth the date, time and manner of delivery of such Designated Securities and
payment therefor. The Pricing Agreement shall also specify (to the extent not
set forth in the Indenture and the registration statement and prospectus with
respect thereto) the terms of such Designated Securities. A Pricing Agreement
shall be in the form of an executed writing (which may be in counterparts), and
may be evidenced by an exchange of telegraphic communications or any other rapid
transmission device designed to produce a written record of communications
transmitted. The obligations of the Underwriters under this Agreement and each
Pricing Agreement shall be several and not joint.

        2. The Company represents and warrants to, and agrees with, each of the
Underwriters that:

             (a) A registration statement on Form S-3 (File No. 333-52224) (the
        "Initial Registration Statement") in respect of the Securities has been
        filed with the Securities and Exchange Commission (the "Commission");
        the Initial Registration Statement and any post-effective amendment
        thereto, each in the form heretofore delivered or to be delivered to the
        Representatives and, excluding exhibits to the Initial Registration
        Statement, but including all documents incorporated by reference in the
        prospectus contained therein, to the Representatives for each of the
        other Underwriters, has been declared effective by the Commission in
        such form; other than a registration statement, if any, increasing the
        size of the offering (a "Rule 462(b) Registration Statement"), filed
        pursuant to Rule 462(b) under the Securities Act of 1933, as amended
        (the "Act"), which became effective upon filing, no other document with
        respect to the Initial Registration Statement or document incorporated
        by reference therein has heretofore been filed or transmitted for filing
        with the Commission (other than prospectuses filed pursuant to Rule
        424(b) of the rules and regulations of the Commission under the Act,
        each in the form heretofore delivered to the Representatives); and no
        stop order suspending the effectiveness of the Initial Registration
        Statement, any post-effective amendment thereto or the Rule 462(b)
        Registration Statement, if any, has been issued and no proceeding for
        that purpose has been initiated or threatened by the Commission (any
        preliminary prospectus included in the Initial Registration Statement or
        filed with the Commission pursuant to Rule 424(a) of the rules and
        regulations of the Commission under the Act, is hereinafter called a
        "Preliminary Prospectus"; the various parts of the Initial Registration
        Statement, any post-effective amendment thereto and the Rule 462(b)
        Registration Statement, if any, including all exhibits thereto and the
        documents incorporated by reference in the prospectus contained in the
        Initial Registration Statement at the time such part of the Initial
        Registration Statement became effective but excluding Form T-1, each as
        amended at the time such part of the Initial Registration Statement
        became effective or such part of the Rule 462(b) Registration Statement,
        if any, became or hereafter becomes effective, are hereinafter
        collectively called the "Registration Statement"; the prospectus
        relating to the Securities, in the form in which it has most recently
        been filed, or transmitted for filing, with the Commission on or prior
        to the date of this Agreement, being hereinafter called the
        "Prospectus"; any reference herein to any Preliminary Prospectus or the
        Prospectus shall be deemed to refer to and include the documents
        incorporated by reference therein pursuant to the applicable form under
        the Act, as of the date of such Preliminary Prospectus or Prospectus, as
        the case may



                                       2
   3

        be; any reference to any amendment or supplement to any Preliminary
        Prospectus or the Prospectus shall be deemed to refer to and include any
        documents filed after the date of such Preliminary Prospectus or
        Prospectus, as the case may be, under the Securities Exchange Act of
        1934, as amended (the "Exchange Act"), and incorporated by reference in
        such Preliminary Prospectus or Prospectus, as the case may be; any
        reference to any amendment to the Initial Registration Statement shall
        be deemed to refer to and include any annual report of the Company filed
        pursuant to Sections 13(a) or 15(d) of the Exchange Act after the
        effective date of the Initial Registration Statement that is
        incorporated by reference in the Registration Statement; and any
        reference to the Prospectus as amended or supplemented shall be deemed
        to refer to the Prospectus as amended or supplemented in relation to the
        applicable Designated Securities in the form in which it is filed with
        the Commission pursuant to Rule 424(b) of the rules and regulations of
        the Commission under the Act in accordance with Section 5(a) hereof,
        including any documents incorporated by reference therein as of the date
        of such filing).

             (b) The documents incorporated by reference in the Prospectus, when
        they became effective or were filed with the Commission, as the case may
        be, conformed in all material respects to the requirements of the
        Exchange Act and the rules and regulations of the Commission thereunder,
        and none of such documents 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, in light of the
        circumstances under which they were made, not misleading; and any
        further documents so filed and incorporated by reference in the
        Prospectus or any further amendment or supplement thereto, when such
        documents become effective or are filed with the Commission, as the case
        may be, will conform in all material respects to the requirements of the
        Exchange Act and the rules and regulations of the Commission thereunder
        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, in light of the circumstances under which they
        were made, not misleading; provided, however, that this representation
        and warranty shall not apply to any statements or omissions made in
        reliance upon and in conformity with information furnished in writing to
        the Company by an Underwriter of Designated Securities through the
        Representatives expressly for use in the Prospectus as amended or
        supplemented relating to such Securities.

             (c) The Registration Statement and the Prospectus conform, and any
        further amendments or supplements to the Registration Statement or the
        Prospectus will conform, in all material respects to the requirements of
        the Act and the Trust Indenture Act of 1939, as amended (the "Trust
        Indenture Act"), and the rules and regulations of the Commission
        thereunder and do not and will not, as of the applicable effective date
        as to the Registration Statement and any amendment thereto and as of the
        applicable filing date as to the Prospectus and any amendment or
        supplement thereto, 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; provided, however, that
        this representation and warranty shall not apply to any statements or
        omissions made in reliance upon and in conformity with information
        furnished in writing to the Company by an Underwriter of Designated
        Securities through the Representatives expressly for use in the
        Prospectus as amended or supplemented relating to such Securities.



                                       3

               (d) Neither the Company nor Northern Pipeline Construction Co. or
        Paiute Pipeline Company (together, the "Subsidiaries"), has sustained
        since the date of the latest audited financial statements included or
        incorporated by reference in the Prospectus any material loss or
        interference with its business from fire, explosion, flood or other
        calamity, whether or not covered by insurance, or from any labor dispute
        or court or governmental action, order or decree, otherwise than as set
        forth or contemplated in the Prospectus; and, since the respective dates
        as of which information is given in the Registration Statement and the
        Prospectus, there has not been any change in the capital stock or
        long-term debt of the Company or any of its subsidiaries, except for
        issuances of capital stock pursuant to the Company's dividend
        reinvestment program and employee benefit plans existing on or prior to
        the date hereof, or any material adverse change, or any development
        involving a prospective material adverse change, in or affecting the
        general affairs, management, financial position, shareholders' equity or
        results of operations of the Company and its subsidiaries, otherwise
        than as set forth or contemplated in the Prospectus.

             (e) The Company has been duly incorporated and is validly existing
        as a corporation in good standing under the laws of the State of
        California, with full corporate power and authority to own, lease and
        operate its properties and to conduct its business as described in the
        Registration Statement and the Prospectus, and is duly registered and
        qualified to conduct its business and is in good standing in each
        jurisdiction or place where the nature of its properties or the conduct
        of its business requires such registration or qualification.

             (f) The Company has an authorized capitalization as set forth in
        the Prospectus, and all of the issued shares of capital stock of the
        Company have been duly and validly authorized and issued and are fully
        paid and non-assessable.

             (g) The Designated Securities have been duly authorized, and, when
        Designated Securities are issued and delivered pursuant to this
        Agreement and the Pricing Agreement with respect to such Designated
        Securities, such Designated Securities will have been duly executed,
        authenticated, issued and delivered and will constitute valid and
        legally binding obligations of the Company entitled to the benefits
        provided by the Indenture, which will be substantially in the form filed
        as an exhibit to the Registration Statement; the Indenture has been duly
        authorized and duly qualified under the Trust Indenture Act and, at the
        Time of Delivery for such Designated Securities (as defined in Section 4
        hereof), the Indenture will constitute a valid and legally binding
        instrument, enforceable in accordance with its terms, subject, as to
        enforcement, to bankruptcy, insolvency, reorganization and other laws of
        general applicability relating to or affecting creditors' rights and to
        general equity principles; and the Indenture conforms, and the
        Designated Securities will conform, to the descriptions thereof
        contained in the Prospectus as amended or supplemented with respect to
        such Designated Securities.

             (h) All of the Company's subsidiaries are listed in an exhibit to
        the Company's Annual Report on Form 10-K for the year ended December 31,
        1999, which is incorporated by reference into the Prospectus. Other than
        the Subsidiaries, (i) no subsidiary of the Company is a "significant
        subsidiary" as defined in Regulation S-X and (ii) no two or more
        subsidiaries of the Company considered in the aggregate constitute a
        "significant subsidiary" as defined in Regulation S-X.

             (i) The issue and sale of the Securities and the compliance by the
        Company with all of the provisions of the Securities, the Indenture,
        this Agreement and any Pricing Agreement, and the consummation of the
        transactions herein and therein contemplated, will not conflict with or
        result in a breach or violation of any of the terms or provisions of, or
        constitute a default under, any indenture, mortgage, deed of trust, loan
        agreement or other agreement or instrument to which the Company or
        either of the Subsidiaries is a party or by which the Company or either
        of the Subsidiaries is bound or to which any of the property or assets
        of the Company or either of the Subsidiaries is subject, nor will such
        action result in: (i) any violation of the provisions of the Articles of
        Incorporation or By-Laws of the Company or either of the Subsidiaries or
        any statute or any order, rule or regulation of any court or
        governmental agency or body having jurisdiction over the Company or
        either of the Subsidiaries or any of their respective properties or (ii)
        the creation or imposition of any lien, charge or encumbrance upon any
        property or assets of the Company or either of the Subsidiaries pursuant
        to the terms of any agreement or instrument to which any of them is a
        party or by which any of them may be bound or to which any of the
        property or assets of any of them is subject; and no consent, approval,
        authorization, order, registration or qualification of or with any such
        court or governmental agency or body is required for the issue and sale
        of the Securities or the consummation by the Company of the transactions
        contemplated by this Agreement or any Pricing Agreement or the
        Indenture, except such as have been, or will have been prior to the Time
        of Delivery, obtained (i) under the Act and the rules and regulations of
        the Commission thereunder, (ii) under the Trust Indenture Act and the
        rules and regulations of the Commission thereunder and (iii) from the
        Public Utilities Commission of the State of California, and such
        consents, approvals, authorizations, registrations or qualifications as
        may be required under state securities or blue sky laws in connection
        with the purchase and distribution of the Securities by the
        Underwriters.

             (j) The statements set forth in the Prospectus under the captions
        "Description of Debt Securities" and "Description of Notes", insofar as
        they purport to constitute a summary of the terms of the Securities, and
        under the captions "Plan of Distribution" and "Underwriting", insofar as
        they purport to describe the provisions of the laws and documents
        referred to therein, are accurate, complete and fair.

             (k) Except as disclosed in the Prospectus, neither the Company nor
        either of the Subsidiaries is: (i) in violation of its respective
        Articles of Incorporation or By-Laws or to the best knowledge of the
        Company after due inquiry, of any law, ordinance, administrative or
        governmental rule or regulation applicable to the Company or either of
        the Subsidiaries, the violation of which would reasonably be expected to
        have a material adverse effect on the general affairs, management,
        financial position, shareholders' equity or results of operations of the
        Company and its subsidiaries (a "Material Adverse Effect") or of any
        decree of any court or governmental agency or body having jurisdiction
        over the Company or either of the Subsidiaries or (ii) is in default in
        the performance or observance of any material obligation, agreement,
        covenant or condition contained in any bond, debenture, note or any
        other evidence of indebtedness, indenture, mortgage, deed of trust, loan
        agreement, lease or other agreement or instrument to which the Company
        or either of the Subsidiaries is a party or by which the Company or
        either of the Subsidiaries or any of their respective properties may be
        bound.



                                       5
   6

             (l) Other than as set forth in the Prospectus, there are no legal
        or governmental proceedings pending to which the Company or any of its
        subsidiaries is a party or of which any property of the Company or any
        of its subsidiaries is the subject which, if determined adversely to the
        Company or any of its subsidiaries, would individually or in the
        aggregate have a Material Adverse Effect and, to the best of the
        Company's knowledge, no such proceedings are threatened or contemplated
        by governmental authorities or threatened by others.

             (m) Arthur Andersen, LLP, who have certified certain financial
        statements of the Company and the Subsidiaries, are independent public
        accountants with respect to the Company as required by the Act and the
        rules and regulations of the Commission thereunder.

             (n) The financial statements, together with related schedules and
        notes, included or incorporated by reference in the Registration
        Statement and the Prospectus (and any amendment or supplement thereto),
        present fairly the consolidated financial position, results of
        operations and changes in financial position of the Company and the
        Subsidiaries on the basis stated in the Registration Statement and the
        Prospectus at the respective dates or for the respective periods to
        which they apply; such statements and related schedules and notes have
        been prepared in accordance with generally accepted accounting
        principles consistently applied throughout the periods involved, except
        as disclosed therein; and the other financial and statistical
        information and data included or incorporated by reference in the
        Registration Statement and the Prospectus (and any amendment or
        supplement thereto) are accurately presented and prepared on a basis
        consistent with such financial statements and the books and records of
        the Company and the Subsidiaries.

             (o) The execution and delivery of, and the performance by the
        Company of its obligations under, this Agreement have been duly and
        validly authorized by the Company, and this Agreement has been duly
        executed and delivered by the Company and constitutes the valid and
        legally binding agreement of the Company, enforceable against the
        Company in accordance with its terms, except as rights to indemnity and
        contribution hereunder, may be limited by applicable law and as limited
        by bankruptcy, insolvency, reorganization, fraudulent conveyance or
        other similar laws affecting creditors rights and general equitable
        principles (whether considered in equity or law).

             (p) Each of the Company and the Subsidiaries has such permits,
        licenses, franchises and authorizations of governmental or regulatory
        authorities (the "permits") as are necessary to own its respective
        properties and to conduct its business in the manner described in the
        Prospectus, except where the failure to fulfill or perform any such
        obligation would not reasonably be expected to have a Material Adverse
        Effect; to the best knowledge of the Company after due inquiry, each of
        the Company and the Subsidiaries has fulfilled and performed all its
        material obligations with respect to such permits, except where the
        failure to fulfill or perform any such obligation would not reasonably
        be expected to have a Material Adverse Effect; and no event has occurred
        that allows, or after notice or lapse of time would allow, revocation or
        termination of any material permits or results or would result in any
        other material impairment of the rights of the holder of any such
        material permits, subject in each case to such qualifications as may be
        set forth in the Prospectus.



                                       6

             (q) No holder of any security of the Company has any right to
        require registration of any security of the Company because of the
        filing of the Registration Statement or consummation of the transactions
        contemplated by this Agreement.

             (r) Neither the Company nor any of its subsidiaries is currently
        subject to regulation under the Public Utility Holding Company Act of
        1935, as amended.

             (s) The Company is not and, after giving effect to the offering and
        sale of the Securities, will not be an "investment company" as such term
        is defined in the Investment Company Act of 1940, as amended.

         3. Upon the execution of the Pricing Agreement applicable to any
Designated Securities and authorization by the Representatives of the release of
such Designated Securities, the several Underwriters propose to offer such
Designated Securities for sale upon the terms and conditions set forth in the
Prospectus as amended or supplemented.

        4. Designated Securities to be purchased by each Underwriter pursuant to
the Pricing Agreement relating thereto, in the form specified in such Pricing
Agreement, and in such authorized denominations and registered in such names as
the Representatives may request upon at least forty-eight hours' prior notice to
the Company, shall be delivered by or on behalf of the Company to the
Representatives for the account of such Underwriter, against payment by such
Underwriter or on its behalf of the purchase price therefor by wire transfer of
Federal (same-day) funds to the account specified by the Company to the
Representatives at least forty-eight hours in advance or at such other place and
time and date as the Representatives and the Company may agree upon in writing,
such time and date being herein called the "Time of Delivery" for such
Securities.

        5. The Company agrees with each of the Underwriters of any Designated
Securities:

             (a) To prepare the Prospectus as amended or supplemented in
        relation to the applicable Designated Securities in a form approved by
        the Representatives and to file such Prospectus pursuant to Rule 424(b)
        of the rules and regulations of the Commission under the Act not later
        than the Commission's close of business on the second business day
        following the execution and delivery of the Pricing Agreement relating
        to the applicable Designated Securities or, if applicable, such earlier
        time as may be required by Rule 424(b); to make no further amendment or
        any supplement to the Registration Statement or Prospectus as amended or
        supplemented after the date of the Pricing Agreement relating to such
        Securities and prior to the Time of Delivery for such Securities which
        shall be disapproved by the Representatives for such Securities promptly
        after reasonable notice thereof; to advise the Representatives promptly
        of any such amendment or supplement after such Time of Delivery and
        furnish the Representatives with copies thereof; to file promptly all
        reports and any definitive proxy or information statements required to
        be filed by the Company with the Commission pursuant to Section 13(a),
        13(c), 14 or 15(d) of the Exchange Act for so long as the delivery of a
        prospectus is required in connection with the offering or sale of such
        Securities, and during such same period to advise the Representatives,
        promptly after it receives notice thereof, of the time when any
        amendment to the Registration Statement has been filed or becomes
        effective or any supplement to the Prospectus or any amended Prospectus
        has been filed with the Commission, of the issuance by the Commission of
        any stop order or of any order preventing or suspending the use of any
        prospectus relating to the Securities, of the suspension of the
        qualification of such



                                       7
   8

        Securities for offering or sale in any jurisdiction, of the initiation
        or threatening of any proceeding for any such purpose, or of any request
        by the Commission for the amending or supplementing of the Registration
        Statement or Prospectus or for additional information; and, in the event
        of the issuance of any such stop order or of any such order preventing
        or suspending the use of any prospectus relating to the Securities or
        suspending any such qualification, to promptly use its best efforts to
        obtain the withdrawal of such order;

             (b) Promptly from time to time to take such action as the
        Representatives may reasonably request to qualify such Securities for
        offering and sale under the securities laws of such jurisdictions as the
        Representatives may request and to comply with such laws so as to permit
        the continuance of sales and dealings therein in such jurisdictions for
        as long as may be necessary to complete the distribution of such
        Securities, provided that in connection therewith the Company shall not
        be required to qualify as a foreign corporation or to file a general
        consent to service of process in any jurisdiction;

             (c) Prior to 10:00 a.m., New York City time, on the New York
        Business Day (as defined in Section 14 hereof) next succeeding the date
        of this Agreement and from time to time, to furnish the Underwriters
        with written and electronic copies of the Prospectus, as amended or
        supplemented, in New York City in such quantities as the Representatives
        may reasonably request, and, if the delivery of a prospectus is required
        at any time in connection with the offering or sale of the Securities
        and if at such time any event shall have occurred as a result of which
        the Prospectus as then amended or supplemented would include an untrue
        statement of a material fact or omit to state any material fact
        necessary in order to make the statements therein, in the light of the
        circumstances under which they were made when such Prospectus is
        delivered, not misleading, or, if for any other reason it shall be
        necessary during such same period to amend or supplement the Prospectus
        or to file under the Exchange Act any document incorporated by reference
        in the Prospectus in order to comply with the Act, the Exchange Act or
        the Trust Indenture Act, to notify the Representatives and upon their
        request to file such document and to prepare and furnish without charge
        to each Underwriter and to any dealer in securities as many written and
        electronic copies as the Representatives may from time to time
        reasonably request of an amended Prospectus or a supplement to the
        Prospectus which will correct such statement or omission or effect such
        compliance;

             (d) To make generally available to its securityholders as soon as
        practicable, but in any event not later than eighteen months after the
        effective date of the Registration Statement (as defined in Rule 158(c)
        of the rules and regulations of the Commission under the Act), an
        earnings statement of the Company and the Subsidiaries (which need not
        be audited) complying with Section 11(a) of the Act and the rules and
        regulations of the Commission thereunder (including, at the option of
        the Company, Rule 158);

             (e) During the period beginning from the date of the Pricing
        Agreement for such Designated Securities and continuing to and including
        the later of: (i) the termination of trading restrictions for such
        Designated Securities, as notified to the Company by the Representatives
        and (ii) the Time of Delivery for such Designated Securities, not to
        offer, sell, contract to sell or otherwise dispose of any debt
        securities of the Company which mature more than one year after such
        Time of Delivery and which are



                                       8
   9

        substantially similar to such Designated Securities, without the prior
        written consent of the Representatives; and

             (f) If the Company elects to rely upon Rule 462(b) of the rules and
        regulations of the Commission under the Act, the Company shall file a
        Rule 462(b) Registration Statement with the Commission in compliance
        with Rule 462(b) by 10:00 P.M., Washington, D.C. time, on the date of
        this Agreement, and the Company shall at the time of filing either pay
        to the Commission the filing fee for the Rule 462(b) Registration
        Statement or give irrevocable instructions for the payment of such fee
        pursuant to Rule 111(b) of the rules and regulations of the Commission
        under the Act.

        6. The Company covenants and agrees with the several Underwriters that
the Company will pay or cause to be paid the following: (a) the fees,
disbursements and expenses of the Company's counsel and accountants in
connection with the registration of the Securities under the Act and all other
expenses in connection with the preparation, printing and filing of the
Registration Statement, any Preliminary Prospectus and the Prospectus and
amendments and supplements thereto and the mailing and delivering of copies
thereof to the Underwriters and dealers; (b) the cost of printing or producing
any Agreement among Underwriters, this Agreement, any Pricing Agreement, any
Indenture, any blue sky and legal investment memoranda, closing documents
(including any compilations thereof) and any other documents in connection with
the offering, purchase, sale and delivery of the Securities; (c) all expenses in
connection with the qualification of the Securities for offering and sale under
state securities laws as provided in Section 5(b) hereof, including the fees and
disbursements of counsel for the Underwriters in connection with such
qualification and in connection with the blue sky and legal investment surveys;
(d) any fees charged by securities rating services for rating the Securities;
(e) any filing fees incident to, and the fees and disbursements of counsel for
the Underwriters in connection with, any required review by the National
Association of Securities Dealers, Inc. of the terms of the sale of the
Securities; (f) the cost of preparing the Securities; (g) the fees and expenses
of any Trustee and any agent of any Trustee and the fees and disbursements of
counsel for any Trustee in connection with any Indenture and the Securities; and
(h) all other costs and expenses incident to the performance of its obligations
hereunder which are not otherwise specifically provided for in this Section. It
is understood, however, that, except as provided in this Section, and Sections 8
and 11 hereof, the Underwriters will pay all of their own costs and expenses,
including the fees of their counsel, transfer taxes on resale of any of the
Securities by them, and any advertising expenses connected with any offers they
may make.

        7. The obligations of the Underwriters of any Designated Securities
under the Pricing Agreement relating to such Designated Securities shall be
subject, in the discretion of the Representatives, to the condition that all
representations and warranties and other statements of the Company in or
incorporated by reference in the Pricing Agreement relating to such Designated
Securities are, at and as of the Time of Delivery for such Designated
Securities, true and correct, the condition that the Company shall have
performed all of its obligations hereunder theretofore to be performed, and the
following additional conditions:

             (a) The Prospectus as amended or supplemented in relation to the
        applicable Designated Securities shall have been filed with the
        Commission pursuant to Rule 424(b) of the rules and regulations of the
        Commission under the Act within the applicable time period prescribed
        for such filing by the rules and regulations of the Commission under the
        Act and in accordance with Section 5(a) hereof; if the Company has
        elected to rely upon Rule 462(b) of the rules and regulations of the
        Commission



                                       9
   10

        under the Act, the Rule 462(b) Registration Statement shall have become
        effective by 10:00 P.M., Washington, D.C. time, on the date of this
        Agreement; no stop order suspending the effectiveness of the
        Registration Statement or any part thereof shall have been issued and no
        proceeding for that purpose shall have been initiated or threatened by
        the Commission; and all requests for additional information on the part
        of the Commission shall have been complied with to the Representatives'
        reasonable satisfaction.

             (b) Counsel for the Underwriters shall have furnished to the
        Representatives their written opinion (a draft of such opinion is
        attached as Annex II(a) hereto), dated the Time of Delivery for such
        Designated Securities, with respect to the matters covered in paragraphs
        (i), (ii), (iii), (v), (vii) and (ix) of subsection (c) below as well as
        such other related matters as the Representatives may reasonably
        request, and such counsel shall have received such papers and
        information as they may reasonably request to enable them to pass upon
        such matters.

              (c) O'Melveny & Myers LLP or other external counsel for the
        Company satisfactory to the Representatives shall have furnished to the
        Representatives their written opinion (a draft of such opinion is
        attached as Annex II(b) hereto), dated the Time of Delivery for such
        Designated Securities, in form and substance satisfactory to the
        Representatives, 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, as
               amended or supplemented, to enter into this Agreement and to
               issue and deliver the Designated Securities as provided therein.

                      (ii) The statements in the Prospectus under the captions
               "Description of Debt Securities" and "Description of Notes,"
               insofar as they purport to constitute a summary of the terms of
               the Indenture and the Notes, fairly present the information
               required to be included therein by the Act and the Trust
               Indenture Act.

                      (iii) The Designated Securities have been duly authorized
               by all necessary corporate action on the part of the Company and
               executed by the Company and, upon payment for and delivery of the
               Designated Securities in accordance with this Agreement,
               constitute legally valid and binding obligations of the Company,
               entitled to the benefits provided by the Indenture.

                      (iv) The Registration Statement has been declared
               effective under the Act and, to the knowledge of such counsel, no
               stop order suspending the effectiveness of the Registration
               Statement has been issued or threatened by the Commission.

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

                      (vi) No consent, approval, authorization or order of, any
               federal, California or New York governmental authority is
               required on the part of the Company for the issuance and sale of
               the Designated Securities as contemplated by the Agreement or the
               Pricing Agreement, except (A)



                                       10
   11

               such as have been obtained under the Act or the Trust Indenture
               Act and the rules and regulations of the Commission thereunder,
               (B) the authorization of the Public Utilities Commission of the
               State of California referred to in Section 2(i) of this Agreement
               which has been obtained and remains in full force and effect and
               is, to the knowledge of such counsel, not the subject of any
               pending or threatened application for rehearing or petition for
               modification, and (C) such as may be required under foreign or
               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 Designated Securities
               by the Underwriters.

                      (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 legally 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 Pricing Agreement, the Indenture and the
               Designated Securities do not violate the Company's Articles of
               Incorporation, By-Laws or any applicable California, New York or
               federal law, ordinance, administrative or governmental rule or
               regulation.

                      (ix) The Company is not an investment company required to
               register under the Investment Company Act of 1940, as amended.

                      (x) The Registration Statement, at its effective date, and
               the Prospectus, as of the date it was filed with the Commission,
               and any further amendments and supplements thereto made by the
               Company prior to the Time of Delivery for the Designated
               Securities at their respective effective dates or respective
               dates of filing, as applicable, appeared on their face to comply
               as to form in all material respects with the requirements of the
               Act and the Trust Indenture Act and the rules and regulations
               thereunder, except that such counsel need express no opinion
               concerning the financial statements and other financial
               information contained or incorporated by reference therein. The
               documents incorporated by reference in the Prospectus, 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 Exchange Act and the rules and regulations of the
               Commission thereunder in effect at such dates, except that such
               counsel need express no opinion concerning the financial
               statements and other financial information contained or
               incorporated by reference therein.

               In connection with such counsel's participation in conferences in
        connection with the preparation of the Registration Statement and the
        Prospectus (excluding the summary financial information attached to any
        Form 8-Ks incorporated by reference in the Registration Statement or
        Prospectus), 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,



                                       11
   12

        completeness or fairness (except as otherwise specifically stated in
        subparagraph (ii) above). However, on the basis of such counsel's review
        of the Registration Statement, the Prospectus as amended or supplemented
        and any further amendments and supplements thereto made by the Company
        prior to the Time of Delivery of the Designated Securities and the
        documents incorporated by reference in the Prospectus and such counsel's
        participation in conferences in connection with the preparation of the
        Registration Statement and the Prospectus as amended or supplemented and
        any further amendments and supplements thereto made by the Company prior
        to the Time of Delivery of the Designated Securities such counsel does
        not believe that the Registration Statement, when the Registration
        Statement became effective, 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, as of its date and on the date of such
        opinion the Prospectus as amended or supplemented and any further
        amendments and supplements thereto made by the Company prior to the Time
        of Delivery of the Designated Securities (in each case including the
        documents then incorporated by reference and considered as a 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: (i) as to the financial statements and
        other financial information included or incorporated by reference in the
        Registration Statement or the Prospectus as amended or supplemented and
        any further amendments and supplements thereto made by the Company prior
        to the Time of Delivery of the Designated Securities, (ii) the statement
        of eligibility, as it may be amended, under the Trust Indenture Act, of
        the Trustee under the Indenture or (iii) any document filed by the
        Company under the Exchange Act, whether before or after the effective
        date of the Registration Statement, except to the extent that any such
        document is a document incorporated by reference in the Registration
        Statement on its effective date, considered as a whole, or is a document
        incorporated by reference and read together with the Prospectus at the
        time it was filed with the Commission and considered as a whole. Counsel
        does not know of any contracts or other documents of a character
        required to be filed as an exhibit to the Registration Statement or the
        documents incorporated by reference therein which are not filed as
        required.

             (d) Robert M. Johnson, Assistant General Counsel for the Company,
        shall have furnished to the Representatives his written opinion (a draft
        of such opinion is attached as Annex II(a) hereto), dated the Time of
        Delivery for such Designated Securities, in form and substance
        satisfactory to the Representatives, to the effect that:

                      (i) The Subsidiaries have been duly incorporated and are
               validly existing in good standing under the laws of the State of
               Nevada, with corporate power to own and lease their respective
               properties and to carry on their respective businesses as
               described in the Prospectus.

                      (ii) The Company has an authorized capitalization as set
               forth in the Prospectus as amended or supplemented and all of the
               issued shares of capital stock of the Company have been duly
               authorized by all necessary corporate action on the part of the
               Company and are validly issued, fully paid and non-assessable.

                      (iii) The Company is duly qualified to do business as a
               foreign corporation and is in good standing under the laws of the
               States of Nevada and Arizona and neither the Company nor the
               Subsidiaries own or lease material properties or conduct material
               business in any other jurisdiction which would require such
               qualification. All the outstanding shares of capital stock of the
               Subsidiaries have been duly authorized and validly issued, are
               fully paid and nonassessable, and



                                       12
   13

               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.

                      (iv) To the best knowledge of such counsel after
               reasonable 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.

                      (v) 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 Designated Securities by the Company; to the best
               knowledge of such counsel after reasonable 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 security of the Company as a result of the issuance
               of the Designated Securities by the Company.

                      (vi) The Company's execution, delivery and performance of
               this Agreement, the Pricing Agreement, the Indenture and the
               Designated Securities do not: (A) violate, breach, or result in a
               default under any existing obligation of the Company or the
               Subsidiaries under any agreement, indenture, lease or other
               instrument to which the Company or the Subsidiaries is a party or
               by which it or any of its properties is bound that is an exhibit
               to the Registration Statement or to any document incorporated by
               reference in the Prospectus or any other material agreement,
               indenture, lease or other instrument known to such counsel after
               reasonable inquiry, (B) breach or otherwise violate any existing
               obligation of the Company under any order, judgment or decree of
               any Arizona, California or Nevada or federal court or
               governmental authority binding on the Company, or (C) violate any
               applicable Arizona or Nevada law, ordinance, administrative or
               governmental rule or regulation.

                      (vii) No consent, approval, authorization or order of, or
               filing with, any federal, California, Arizona or Nevada
               governmental authority is required on the part of the Company for
               the issuance and sale of the Designated Securities as
               contemplated by this Agreement, except: (A) such as have been
               obtained under the Act, the Trust Indenture Act or the rules and
               regulations of the Commission thereunder, (B) the authorization
               of the Public Utilities Commission of the State of California
               referred to in Section 2(i) of this Agreement which has been
               obtained, remains in full force and effect and is, to the best
               knowledge of such counsel, not the subject of any pending or
               threatened application for rehearing or petition for
               modification, and (C) such as may be required under applicable
               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 Designated Securities
               by the Underwriters.

                      (viii) 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 any of its
               subsidiaries, or to which the Company or



                                       13
   14

               any of its subsidiaries or any of their property, is subject,
               which are required to be described in the Registration Statement
               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 (c) above.

               In rendering their opinions as aforesaid, counsel may rely upon
        an opinion or opinions, each dated the Time of Delivery for such
        Designated Securities, 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 LLP, 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 Underwriters which states that the Underwriters 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 Underwriters are justified in relying
        thereon.

                (e) On the date of the Pricing Agreement for such Designated
        Securities at a time prior to the execution of the Pricing Agreement
        with respect to such Designated Securities and at the Time of Delivery
        for such Designated Securities, Arthur Andersen LLP, independent
        certified public accountants, shall have furnished to the
        Representatives a letter, dated the date of the Pricing Agreement and a
        letter dated such Time of Delivery, respectively, to the effect set
        forth in Annex II hereto, and in form and substance satisfactory to the
        Representatives.

               (f) (i) Neither the Company nor either of the Subsidiaries shall
               have sustained since the date of the latest audited financial
               statements included or incorporated by reference in the
               Prospectus as amended prior to the date of the Pricing Agreement
               relating to the Designated Securities any loss or interference
               with its business from fire, explosion, flood or other calamity,
               whether or not covered by insurance, or from any labor dispute or
               court or governmental action, order or decree, otherwise than as
               set forth or contemplated in the Prospectus as amended prior to
               the date of the Pricing Agreement relating to the Designated
               Securities, and (ii) since the respective dates as of which
               information is given in the Prospectus as amended prior to the
               date of the Pricing Agreement relating to the Designated
               Securities there shall not have been any change in the capital
               stock or long-term debt of the Company or its subsidiaries or any
               change, or any development involving a prospective change, in or
               affecting the general affairs, management, financial position,
               shareholders' equity or results of operations of the Company and
               its subsidiaries, otherwise than as set forth or contemplated in
               the Prospectus as amended prior to the date of the Pricing
               Agreement relating to the Designated Securities, the effect of
               which, in any such case described in clause (i) or (ii), is in
               the judgment of the Representatives so material and adverse as to
               make it impracticable or inadvisable to proceed with the public
               offering or the delivery of the Designated Securities on the
               terms and in the manner contemplated in the Prospectus as first
               amended or supplemented relating to the Designated Securities.

               (g) On or after the date of the Pricing Agreement relating to the
        Designated Securities: (i) no downgrading shall have occurred in the
        rating accorded the Company's debt securities or preferred securities by
        any "nationally recognized statistical rating



                                       14
   15

        organization", as that term is defined by the Commission for purposes of
        Rule 436(g)(2) of the rules and regulations of the Commission under the
        Act, and (ii) no such organization shall have publicly announced that it
        has under surveillance or review, with possible negative implications,
        its rating of any of the Company's debt securities or preferred
        securities.

               (h) On or after the date of the Pricing Agreement relating to the
        Designated Securities there shall not have occurred any of the
        following: (i) a suspension or material limitation in trading in
        securities generally on the New York Stock Exchange (the "NYSE"); (ii) a
        suspension or material limitation in trading in the Company's securities
        on the NYSE; (iii) a general moratorium on commercial banking activities
        declared by either Federal or New York State authorities; or (iv) a
        material adverse change in financial markets or the outbreak or
        escalation of hostilities involving the United States or the declaration
        by the United States of a national emergency or war, if the effect of
        any such event specified in this clause (iv) in the judgment of the
        Representatives makes it impracticable or inadvisable to proceed with
        the public offering or the delivery of the Designated Securities on the
        terms and in the manner contemplated in the Prospectus as first amended
        or supplemented relating to the Designated Securities.

               (i) The Company shall have complied with the provisions of
        Section 5(c) hereof with respect to the furnishing of prospectuses on
        the New York Business Day next succeeding the date of this Agreement.

               (j) The Company shall have furnished or caused to be furnished to
        the Representatives at the Time of Delivery for the Designated
        Securities a certificate or certificates of officers of the Company
        satisfactory to the Representatives as to the accuracy of the
        representations and warranties of the Company herein at and as of such
        Time of Delivery, as to the performance by the Company of all of its
        obligations hereunder to be performed at or prior to such Time of
        Delivery, as to the matters set forth in subsections (a) and (f) of this
        Section and as to such other matters as the Representatives may
        reasonably request.

        8. (a) The Company will indemnify and hold harmless each Underwriter
        against any losses, claims, damages or liabilities, joint or several, to
        which such Underwriter may become subject, under the Act or otherwise,
        insofar as such losses, claims, damages or liabilities (or actions in
        respect thereof) arise out of or are based upon an untrue statement or
        alleged untrue statement of a material fact contained in any Preliminary
        Prospectus, any preliminary prospectus supplement, the Registration
        Statement, the Prospectus as amended or supplemented and any other
        prospectus relating to the Securities, or any amendment or supplement
        thereto, or arise out of or are based upon the omission or alleged
        omission to state therein a material fact required to be stated therein
        or necessary to make the statements therein not misleading, and will
        reimburse each Underwriter for any legal or other expenses reasonably
        incurred by such Underwriter in connection with investigating or
        defending any such action or claim as such expenses are incurred;
        provided, however, that the Company shall not be liable in any such case
        to the extent that any such loss, claim, damage or liability arises out
        of or is based upon an untrue statement or alleged untrue statement or
        omission or alleged omission made in any Preliminary Prospectus, any
        preliminary prospectus supplement, the Registration Statement, the
        Prospectus as



                                       15
   16

        amended or supplemented and any other prospectus relating to the
        Securities, or any such amendment or supplement in reliance upon and in
        conformity with written information furnished to the Company by any
        Underwriter of Designated Securities through the Representatives
        expressly for use in the Prospectus as amended or supplemented relating
        to such Securities; and provided, further, that the Company shall not be
        liable to any Underwriter under the indemnity agreement in subsection
        (a) of this Section with respect to any Preliminary Prospectus to the
        extent that any such loss, claim, damage or liability of such
        Underwriter results from the fact that such Underwriter sold the
        Designated Securities to a person as to whom it shall be established
        that there was not sent or given, at or prior to the written
        confirmation of such sale, a copy of the Prospectus (excluding documents
        incorporated by REFERENCE) or of the Prospectus as then amended or
        supplemented (excluding documents incorporated by reference) in any case
        where such delivery is required by the Act if the Company has previously
        furnished copies thereof in sufficient quantity to such Underwriter and
        the loss, claim, damage or liability of such Underwriter results from an
        untrue statement or omission of a material fact contained in the
        Preliminary Prospectus which was identified in writing at such time to
        such Underwriter and corrected in the Prospectus (excluding documents
        incorporated by reference) or in the Prospectus as then amended or
        supplemented (excluding documents incorporated by reference) and such
        correction would have cured the defect giving rise to such loss, claim,
        damage or liability.

               (b) Each Underwriter will indemnify and hold harmless the Company
        against any losses, claims, damages or liabilities to which the Company
        may become subject, under the Act or otherwise, insofar as such losses,
        claims, damages or liabilities (or actions in respect thereof) arise out
        of or are based upon an untrue statement or alleged untrue statement of
        a material fact contained in any Preliminary Prospectus, any preliminary
        prospectus supplement, the Registration Statement, the Prospectus as
        amended or supplemented and any other prospectus relating to the
        Securities, or any amendment or supplement thereto, or arise out of or
        are based upon the omission or alleged omission to state therein a
        material fact required to be stated therein or necessary to make the
        statements therein not misleading, in each case to the extent, but only
        to the extent, that such untrue statement or alleged untrue statement or
        omission or alleged omission was made in any Preliminary Prospectus, any
        preliminary prospectus supplement, the Registration Statement, the
        Prospectus as amended or supplemented and any other prospectus relating
        to the Securities, or any such amendment or supplement in reliance upon
        and in conformity with written information furnished to the Company by
        such Underwriter through the Representatives expressly for use therein;
        and will reimburse the Company for any legal or other expenses
        reasonably incurred by the Company in connection with investigating or
        defending any such action or claim as such expenses are incurred.

               (c) Promptly after receipt by an indemnified party under
        subsection (a) or (b) above of notice of the commencement of any action,
        such indemnified party shall, if a claim in respect thereof is to be
        made against the indemnifying party under such subsection, notify the
        indemnifying party in writing of the commencement thereof; but the
        omission so to notify the indemnifying party shall not relieve it from
        any liability which it may have to any indemnified party otherwise than
        under such subsection. In case any such action shall be brought against
        any indemnified party and it shall notify the indemnifying party of the
        commencement thereof, the indemnifying party shall be



                                       16
   17

        entitled to participate therein and, to the extent that it shall wish,
        jointly with any other indemnifying party similarly notified, to assume
        the defense thereof, with counsel satisfactory to such indemnified party
        (who shall not, except with the consent of the indemnified party, be
        counsel to the indemnifying party), and, after notice from the
        indemnifying party to such indemnified party of its election so to
        assume the defense thereof, the indemnifying party shall not be liable
        to such indemnified party under such subsection for any legal expenses
        of other counsel or any other expenses, in each case subsequently
        incurred by such indemnified party, in connection with the defense
        thereof other than reasonable costs of investigation. No indemnifying
        party shall, without the written consent of the indemnified party,
        effect the settlement or compromise of, or consent to the entry of any
        judgment with respect to, any pending or threatened action or claim in
        respect of which indemnification or contribution may be sought hereunder
        (whether or not the indemnified party is an actual or potential party to
        such action or claim) unless such settlement, compromise or judgment (i)
        includes an unconditional release of the indemnified party from all
        liability arising out of such action or claim and (ii) does not include
        a statement as to or an admission of fault, culpability or a failure to
        act, by or on behalf of any indemnified party.

               (d) If the indemnification provided for in this Section 8 is
        unavailable to or insufficient to hold harmless an indemnified party
        under subsection (a) or (b) above in respect of any losses, claims,
        damages or liabilities (or actions in respect thereof) referred to
        therein, then each indemnifying party shall contribute to the amount
        paid or payable by such indemnified party as a result of such losses,
        claims, damages or liabilities (or actions in respect thereof) in such
        proportion as is appropriate to reflect the relative benefits received
        by the Company on the one hand and the Underwriters of the Designated
        Securities on the other from the offering of the Designated Securities
        to which such loss, claim, damage or liability (or action in respect
        thereof) relates. If, however, the allocation provided by the
        immediately preceding sentence is not permitted by applicable law or if
        the indemnified party failed to give the notice required under
        subsection (c) above, then each indemnifying party shall contribute to
        such amount paid or payable by such indemnified party in such proportion
        as is appropriate to reflect not only such relative benefits but also
        the relative fault of the Company on the one hand and the Underwriters
        of the Designated Securities on the other in connection with the
        statements or omissions which resulted in such losses, claims, damages
        or liabilities (or actions in respect thereof), as well as any other
        relevant equitable considerations. The relative benefits received by the
        Company on the one hand and such Underwriters on the other shall be
        deemed to be in the same proportion as the total net proceeds from such
        offering (before deducting expenses) received by the Company bear to the
        total underwriting discounts and commissions received by such
        Underwriters. The relative fault shall be determined by reference to,
        among other things, whether the untrue or alleged untrue statement of a
        material fact or the omission or alleged omission to state a material
        fact relates to information supplied by the Company on the one hand or
        such Underwriters on the other and the parties' relative intent,
        knowledge, access to information and opportunity to correct or prevent
        such statement or omission. The Company and the Underwriters agree that
        it would not be just and equitable if contribution pursuant to this
        subsection (d) were determined by pro rata allocation (even if the
        Underwriters were treated as one entity for such purpose) or by any
        other method of allocation which does not take account of the equitable
        considerations referred to above in this subsection (d). The amount paid
        or payable by an indemnified party as a



                                       17
   18

        result of the losses, claims, damages or liabilities (or actions in
        respect thereof) referred to above in this subsection (d) shall be
        deemed to include 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 subsection
        (d), no Underwriter shall be required to contribute any amount in excess
        of the amount by which the total price at which the applicable
        Designated Securities underwritten by it and distributed to the public
        were offered to the public exceeds the amount of any damages which such
        Underwriter has otherwise been required to pay by reason of such untrue
        or alleged untrue statement or omission or alleged omission. No person
        guilty of fraudulent misrepresentation (within the meaning of Section
        11(f) of the Act) shall be entitled to contribution from any person who
        was not guilty of such fraudulent misrepresentation. The obligations of
        the Underwriters of Designated Securities in this subsection (d) to
        contribute are several in proportion to their respective underwriting
        obligations with respect to such Securities and not joint.

               (e) The obligations of the Company under this Section 8 shall be
        in addition to any liability which the Company may otherwise have and
        shall extend, upon the same terms and conditions, to each person, if
        any, who controls any Underwriter within the meaning of the Act; and the
        obligations of the Underwriters under this Section 8 shall be in
        addition to any liability which the respective Underwriters may
        otherwise have and shall extend, upon the same terms and conditions, to
        each officer and director of the Company and to each person, if any, who
        controls the Company within the meaning of the Act.

        9. (a) If any Underwriter shall default in its obligation to purchase
        the Designated Securities which it has agreed to purchase under the
        Pricing Agreement relating to such Designated Securities, the
        Representatives may in their discretion arrange for themselves or
        another party or other parties to purchase such Designated Securities on
        the terms contained herein. If within thirty-six hours after such
        default by any Underwriter the Representatives do not arrange for the
        purchase of such Designated Securities, then the Company shall be
        entitled to a further period of thirty-six hours within which to procure
        another party or other parties satisfactory to the Representatives to
        purchase such Designated Securities on such terms. In the event that,
        within the respective prescribed period, the Representatives notify the
        Company that they have so arranged for the purchase of such Designated
        Securities, or the Company notifies the Representatives that it has so
        arranged for the purchase of such Designated Securities, the
        Representatives or the Company shall have the right to postpone the Time
        of Delivery for such Designated Securities for a period of not more than
        seven days, in order to effect whatever changes may thereby be made
        necessary in the Registration Statement or the Prospectus as amended or
        supplemented, or in any other documents or arrangements, and the Company
        agrees to file promptly any amendments or supplements to the
        Registration Statement or the Prospectus which in the opinion of the
        Representatives may thereby be made necessary. The term "Underwriter" as
        used in this Agreement shall include any person substituted under this
        Section with like effect as if such person had originally been a party
        to the Pricing Agreement with respect to such Designated Securities.

               (b) If, after giving effect to any arrangements for the purchase
        of the Designated Securities of a defaulting Underwriter or Underwriters
        by the Representatives and the Company as provided in subsection (a)
        above, the aggregate



                                       18
   19

        principal amount of such Designated Securities which remains unpurchased
        does not exceed one-eleventh of the aggregate principal amount of the
        Designated Securities, then the Company shall have the right to require
        each non-defaulting Underwriter to purchase the principal amount of
        Designated Securities which such Underwriter agreed to purchase under
        the Pricing Agreement relating to such Designated Securities and, in
        addition, to require each non-defaulting Underwriter to purchase its pro
        rata share (based on the principal amount of Designated Securities which
        such Underwriter agreed to purchase under such Pricing Agreement) of the
        Designated Securities of such defaulting Underwriter or Underwriters for
        which such arrangements have not been made; but nothing herein shall
        relieve a defaulting Underwriter from liability for its default.

               (c) If, after giving effect to any arrangements for the purchase
        of the Designated Securities of a defaulting Underwriter or Underwriters
        by the Representatives and the Company as provided in subsection (a)
        above, the aggregate principal amount of Designated Securities which
        remains unpurchased exceeds one-eleventh of the aggregate principal
        amount of the Designated Securities, as referred to in subsection (b)
        above, or if the Company shall not exercise the right described in
        subsection (b) above to require non-defaulting Underwriters to purchase
        Designated Securities of a defaulting Underwriter or Underwriters, then
        the Pricing Agreement relating to such Designated Securities shall
        thereupon terminate, without liability on the part of any non-defaulting
        Underwriter or the Company, except for the expenses to be borne by the
        Company and the Underwriters as provided in Section 6 hereof and the
        indemnity and contribution agreements in Section 8 hereof; but nothing
        herein shall relieve a defaulting Underwriter from liability for its
        default.

        10. The respective indemnities, agreements, representations, warranties
and other statements of the Company and the several Underwriters, as set forth
in this Agreement or made by or on behalf of them, respectively, pursuant to
this Agreement, shall remain in full force and effect, regardless of any
investigation (or any statement as to the results thereof) made by or on behalf
of any Underwriter or any controlling person of any Underwriter, or the Company,
or any officer or director or controlling person of the Company, and shall
survive delivery of and payment for the Securities.

        11. If any Pricing Agreement shall be terminated pursuant to Section 9
hereof, the Company shall not then be under any liability to any Underwriter
with respect to the Designated Securities covered by such Pricing Agreement
except as provided in Sections 6 and 8 hereof; but, if for any other reason
Designated Securities are not delivered by or on behalf of the Company as
provided herein, the Company will reimburse the Underwriters through the
Representatives for all out-of-pocket expenses approved in writing by the
Representatives, including fees and disbursements of counsel, reasonably
incurred by the Underwriters in making preparations for the purchase, sale and
delivery of such Designated Securities, but the Company shall then be under no
further liability to any Underwriter with respect to such Designated Securities
except as provided in Sections 6 and 8 hereof.

        12. In all dealings hereunder, the Representatives of the Underwriters
of Designated Securities shall act on behalf of each of such Underwriters, and
the parties hereto shall be entitled to act and rely upon any statement,
request, notice or agreement on behalf of any Underwriter made or given by such
Representatives jointly or by such of the Representatives, if any, as may be
designated for such purpose in the Pricing Agreement.

        All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to the address of the Representatives as set forth in the
Pricing Agreement; and if to the Company shall be delivered or sent by mail,
telex or facsimile transmission to the address of the Company set forth in the
Registration Statement: Attention: Secretary; provided, however, that any notice
to an Underwriter pursuant to Section 8(c) hereof shall be delivered or sent by
mail, telex or facsimile transmission to such Underwriter at its address set
forth in its Underwriters' Questionnaire, or telex constituting such
Questionnaire, which address will be supplied to the Company by the
Representatives upon request. Any such statements, requests, notices or
agreements shall take effect upon receipt thereof.

        13. This Agreement and each Pricing Agreement shall be binding upon, and
inure solely to the benefit of, the Underwriters, the Company and, to the extent
provided in Sections 8 and 10 hereof, the officers and directors of the Company
and each person who controls the Company or any Underwriter, and their
respective heirs, executors, administrators, successors and assigns, and no
other person shall acquire or have any right under or by virtue of this
Agreement or any such Pricing Agreement. No purchaser of any of the Securities
from any Underwriter shall be deemed a successor or assign by reason merely of
such purchase.

        14. Time shall be of the essence of each Pricing Agreement. As used
herein, "business day" shall mean any day when the Commission's office in
Washington, D.C. is open for business. As used herein, "New York Business Day"
shall mean any day other than Saturday, Sunday or any day on which banks located
in the State of New York are authorized or obligated to close.

        15. This Agreement and each Pricing Agreement shall be governed by and
construed in accordance with the laws of the State of New York.

        16. This Agreement and each Pricing Agreement may be executed by any one
or more of the parties hereto and thereto in any number of counterparts, each of
which shall be deemed to be an original, but all such respective counterparts
shall together constitute one and the same instrument.
