         1. Representations, Warranties and Agreements of the Company. The
Company represents, warrants and agrees that:

              (a) A registration statement on Form S-3 (No. 333-62697),
    including a form of prospectus relating to certain debt and equity
    securities (the "Registered Securities") to be issued from time to time by
    the Company, has been filed with the Securities and Exchange Commission
    (the "Commission") and has been declared effective under the Securities Act
    of 1933, as amended (the "Act"), and the Indenture has been qualified under
    the Trust Indenture Act of 1939 (the "Trust Indenture Act"). The Company
    proposes to file with the Commission pursuant to Rule 424 under the Act, a
    form of prospectus supplement specifically relating to the Securities. The
    regis tration statement, as amended at the time of this Agreement,
    including all material incorporated by reference therein, is hereinafter
    referred to as the "Registration State ment," and the form of prospectus
    included in such Registration Statement, as supple mented by the prospectus
    supplement specifically relating to the Securities, as first filed with the
    Commission pursuant to and in accordance with Rule 424(b) ("Rule 424(b)")
    under the Act, including all material incorporated by reference therein, is
    hereinafter referred to as the "Prospectus". No document has been or will
    be prepared or distrib uted in reliance on Rule 434 under the Act.

              (b) On the effective date of the registration statement relating
    to the Registered Securities, such registration statement conformed in all
    material respects to the requirements of the Act and the rules and
    regulations of the Commission ("Rules and Regulations") thereunder and did
    not include any untrue statement of a material fact or omit to state any
    material fact required to be stated therein or necessary to make the
    statements therein not misleading, and on the date of this Agreement, the
    Registration Statement conforms, and at the time of filing of the
    Prospectus pursuant to Rule 424(b), the Registration Statement and the
    Prospectus will conform, in all material respects to the requirements of
    the Act and the Rules and Regulations, and none of such documents includes,
    or will include, any untrue statement of a material fact or omits, or will
    omit, to state any material fact required to be stated therein or necessary
    to make the statements therein (with respect to the Prospectus, in the
    light of the circumstances under which they were made) not misleading,
    except that the foregoing does not apply to statements in or omissions from
    the Registration Statement or the Prospectus based upon written information
    furnished to the Company by or on behalf of any Underwriter through the
    Representatives specifically for use therein, it being understood and
    agreed that the only such information is that described as such in Section
    8(e); and the Indenture conforms in all material respects to the
    requirements of the Trust Indenture Act and the Rules and Regulations of
    the Commission thereunder.

              (c) The documents incorporated by reference in the Registration
    Statement and the Prospectus, when they became effective or were last
    amended or filed

                                       2

<PAGE>

    with the Commission, as the case may be, conformed in all material respects
    to the requirements of the Act or the Securities Exchange Act of 1934, as
    amended (the "Exchange Act"), as applicable, and the Rules and Regulations,
    and none of such docu ments 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 in light of the
    circumstances under which they were made, and any further documents so
    filed and incorporated by reference in the Registration Statement and the
    Prospectus, when such documents become effective or are filed with the
    Commission, as the case may be, shall conform in all material respects to
    the requirements of the Act and the Exchange Act as applicable, and the
    Rules and Regulations and shall 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 in light
    of the circumstances under which they were made.

              (d) The Company, each Subsidiary (as defined below) and each
    Joint Venture (as defined below) have been duly organized and are validly
    existing and, if applicable, in good standing under the laws of their
    respective jurisdictions of organization as a corporation, limited
    liability company or partnership, as the case may be, and have the power
    and authority to own, lease and operate their property and conduct their
    businesses as described in the Prospectus; the Company, the Subsidiaries
    and the Joint Ventures are duly qualified to do business and are in good
    standing as foreign corporations or foreign partnerships, as the case may
    be, in each jurisdiction, domestic or foreign, in which such registration
    or qualification or good standing is required (whether by reason of the
    ownership or leasing of property, the conduct of business or otherwise),
    except where the failure to so register or qualify or be in good standing
    is not reasonably likely to have a material adverse effect on the financial
    condition, business or results of operations of the Company, the
    Subsidiaries and the Joint Ventures taken as a whole. For purposes of this
    Agreement, (A) the term "Subsidiary" shall mean the entities listed in
    Schedule B hereto ("Schedule B") and (B) the term "Joint Venture" shall
    mean the entities listed in Schedule C hereto ("Schedule C"), it being
    understood that such term means the general or limited partnership or other
    joint venture entity and not the individual general or limited partners or
    other joint venturers thereof. The Subsidiaries listed in Schedule B are
    all the material direct and indirect "subsidiaries" of the Company, as such
    term is defined in Rule 405 of the Rules and Regulations, and are all of
    the "Significant Subsidiaries" of the Company, as such term is defined in
    Rule 1-02 of Regulation S-X.

              (e) All the outstanding shares of capital stock of each
    Subsidiary have been duly and validly authorized and issued and are
    fully-paid and nonassessable; and except as otherwise set forth in Schedule
    B or disclosed in or contemplated by the Prospectus, all outstanding shares
    of capital stock of each Subsidiary are owned beneficially by the Company
    free and clear of any material claims, liens, encumbrances and security
    interests. All of the partnership interests in the Joint Ventures
    beneficially

                                       3

<PAGE>

    owned by the Company (as reflected in Schedule C) have been duly and
    validly autho rized and issued and, except as otherwise set forth in
    Schedule C or disclosed in or contemplated by the Prospectus, are owned
    beneficially by the Company free and clear of any material claims, liens,
    encumbrances and security interests.

              (f) All the outstanding shares of capital stock of the Company
    have been duly and validly authorized and issued and are fully paid and
    nonassessable.

              (g) The Securities have been duly authorized by the Company, and,
    when duly executed, authenticated, issued and delivered against payment
    therefor as contemplated hereby and by the Indenture, shall be validly
    issued and outstanding, and shall constitute valid and binding obligations
    on the part of the Company, entitled to the benefits of the Indenture, and
    enforceable against the Company in accordance with their terms, except as
    enforcement may be limited by applicable bankruptcy, fraudulent conveyance,
    insolvency, reorganization, moratorium or other similar laws affecting
    creditors' rights generally and by equitable principles generally; and the
    Securities, when issued and delivered, shall conform in all material
    respects to the descriptions thereof contained in the Prospectus.

              (h) Each of the Base Indenture and the Second Supplemental
    Indenture has been duly authorized, and when duly executed and delivered by
    the Company, shall constitute a valid and binding agreement on the part of
    the Company, enforceable against the Company in accordance with its terms,
    except as enforcement may be limited by applicable bankruptcy, fraudulent
    conveyance, insolvency, reorganization, moratorium or other similar laws
    affecting creditors' rights generally and by equitable principles
    generally; and the Base Indenture and the Second Supplemental Indenture,
    when executed and delivered, shall conform in all material respects to the
    descriptions thereof contained in the Prospectus.

              (i) The use of the proceeds of the offering of the Securities as
    described in the Prospectus has been duly authorized by all necessary
    action on the part of the Company.

              (j) Except as disclosed in the Prospectus, there are no
    contracts, agreements or understandings between the Company and any person
    that would give rise to a valid claim against the Company or any
    Underwriter for a brokerage commission, finder's fee or other like payment
    in connection with the offering of the Securities.

              (k) Except as disclosed in the Prospectus, there are no
    contracts, agreements or understandings which have not been satisfied or
    waived between the Company and any person requiring the Company to include
    securities of the Company owned or to be owned by such person in the
    securities registered pursuant to the Registration Statement.

                                       4

              (l) The execution, delivery and performance of this Agreement,
    the Base Indenture and the Second Supplemental Indenture, and the issuance
    and sale of the Securities and the use of the proceeds of the offering of

    the corporate charter or by-laws or partnership agreement of the Company,
    any Subsidiary or any Joint Venture, (B) conflict with, result in the
    creation or imposition of any lien, charge or other encumbrance (other than

    breach of, or default under, any agreement, indenture or other instrument
    to which the Company, any Subsidiary or any Joint Venture is a party or by
    which the Company, any Subsidiary or any Joint Venture is bound or to which
    any of the properties of the Company, any Subsidiary or any Joint Venture
    is subject, or (C) result in a violation of any statute, rule, regulation,
    order, judgment or decree of any court or governmental agency, body or
    authority having jurisdiction over the Company, any Subsidiary or any Joint
    Venture or any of their properties where any such conflicts, encumbrances,
    breaches, defaults or violations under clauses (B) or (C), individually or
    in the aggregate, is reasonably likely to (i) have a material adverse
    effect on the financial condition, business or results of operations of the
    Company, the Subsidiaries and the Joint Ventures taken as a whole or (ii)
    impair the validity or enforceability of the Securities under the Act.

    Supplemental Indenture and the Securities.

              (o) This Agreement has been duly authorized, executed and

    and valid title to, or valid and enforceable leasehold or contractual
    interests in, all real properties and all other properties and assets owned

    among the Company, Maverick Reincorporation Sub, Inc., MidAmerican and MAVH
    Inc.(including all exhibits and schedules thereto, the "MidAmerican Merger
    Agreement") has been duly and validly authorized, executed and delivered by
    the Company and, assuming the due execution and delivery by the other
    parties thereto, constitutes a valid and binding agreement on the part of
    the Company, enforceable against the Company in accordance with its terms,
    except as enforcement may be limited by applicable bankruptcy, fraudulent
    conveyance, insolvency, reorganization, moratorium or other similar laws
    affecting creditors' rights generally and by equitable principles
    generally. No facts have come to the Company's attention that have led the
    Company to believe that the MidAmerican Merger or the reincorporation of
    the Company contemplated by the MidAmerican Merger Agreement will not be
    consummated on terms (subject to satisfaction of applicable conditions)
    that are materially consistent with those described in the Prospectus.

              (aj) The Company's pending acquisition of MidAmerican Energy
    Holdings Company (the "MidAmerican Merger") and the consummation of the
    transactions contemplated thereby, shall not (A) conflict with the
    corporate charter of the Company, (B) constitute a breach of, or default
    under, any agreement, indenture or other instrument to which the Company,
    any Subsidiary or any Joint Venture is a party or by

                                       11

    which the Company, any Subsidiary or any Joint Venture is bound or to which
    any of the properties of the Company, any Subsidiary or Joint Venture is
    subject, or (C) result in a violation of any statue, rule, regulation,
    order, judgment or decree of any court or governmental agency, body or
    authority, having jurisdiction over the Company or, to the best of the
    Company's knowledge, MidAmerican; except in the case of clauses (B) and (C)
    such breaches, defaults or violations which, individually or in the
    aggregate, would not have a material adverse effect on the financial
    condition, business or results of operations of the Company, the
    Subsidiaries and Joint Ventures taken as a whole.

              (ak) To the best of the Company's knowledge, the representations

    are true and correct in all material respects as if made on the date
    hereof.

                   (a) The Company will file the Prospectus with the Commission
         pursuant to and in accordance with subparagraph (2) (or, if applicable
         and if consented to by Lehman, subparagraph (5)) of Rule 424(b) not
         later than the second business day following the execution and
         delivery of this Agreement. The Company will advise CSFB promptly of
         any such filing pursuant to Rule 424(b).

                   (b) The Company will advise the Representatives promptly of
         any proposal to amend or supplement the Registration Statement or the

         unreasonably withheld; and the Company will also advise the
         Representatives promptly of the effectiveness of any amendment or
         supplementation of the Registration Statement or the Prospectus and of
         the institution by the Commission of any stop order proceedings in
         respect of the Registration Statement and will use its reasonable best
         efforts to prevent the issuance of any such stop order and to obtain
         as soon as possible its lifting, if issued.

                   (c) If, at any time when a prospectus relating to the
         Securities is required, in the opinion of counsel for the
         Underwriters, to be delivered under the Act in connection with sales
         by any Underwriter or dealer, any event occurs 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 to make the statements therein, in the light of the
         circumstances under which they were made, not misleading, or if it is
         necessary at any such time to amend the Prospectus to comply with the
         Act, the Company will promptly notify the Representatives of such
         event and will promptly prepare and file with the Commission, at its
         own expense, an amendment or supplement which will correct such
         statement or omission or an amendment which will effect such
         compliance. Neither the Representatives' consent to, nor the
         Underwriters' delivery of, any such amendment or supplement shall
         constitute a waiver of any of the conditions set forth in Section 7.

                                       13

<PAGE>

                   (d) As soon as practicable, but not later than 16 months

         recent Annual Report on Form 10- K filed with the Commission prior to
         the date of this Agreement, which will satisfy the provisions of
         Section 11(a) of the Act.

                   (e) The Company will furnish to the Representatives copies
         of the Registration Statement (three of which will be signed and will
         include all exhibits), each preliminary prospectus and preliminary
         prospectus supplement relating to the Securities, and, so long as
         delivery of a prospectus relating to the Securities is required to be
         delivered under the Act in connection with sales by any Underwriter or
         dealer, the Prospectus and all amendments and supplements to such
         documents, in each case as soon as available and in such quantities as
         the Representatives request. The Company will pay the expenses of
         printing and distributing to the Underwriters all such documents.

         Securities for sale under the laws of such jurisdictions in the United
         States as the Representatives designate and will continue such
         qualifications in effect so long as required for the distribution,
         provided that, in connection therewith the Company shall not, with
         respect to any such jurisdiction, be required to qualify as a foreign
         corporation, to file a general consent to service of process or to
         take any other action that would subject it to service of process in
         suits other than those arising out of the offering of the Securities
         or to taxation in respect of doing business in any jurisdiction in
         which it is not other wise subject.

                   (g) During the period of three years hereafter, the Company
         will furnish to the Representatives and, upon request, to each of the
         Underwriters, as soon as practicable, after the end of each fiscal

         a copy of each report and any definitive proxy statement of the
         Company filed with the Commission under the Exchange Act or mailed to

                   (h) The Company will indemnify and hold harmless the
         Underwriters against any documentary, stamp or similar issuance tax,
         including any interest and penalties, on the issuance and sale of the
         Securities and on the execution and delivery of this Agreement. All

         In that event, the Company shall pay such additional amounts as may be
         necessary in order that the net amounts received after such

                                       14

<PAGE>

         withholding or deduction shall equal the amounts that would have been
         re ceived if no withholding or deduction had been made.

                   (i) The Company shall apply the net proceeds from the sale
         of the Notes as set forth in the Prospectus.

         distribution of the Securities, will be taken by the Company in any
         jurisdiction outside the United States that would permit a public
         offering of the Securities, or possession or distribution of the
         Prospectus, or any amendment or supplement thereto, or any related
         preliminary prospectus or preliminary prospectus supplement issued in
         connection with the offering of the Securities, or any other offering
         material, in any country or jurisdiction where action for that purpose
         is required.

         6. Expenses. The Company agrees to pay (a) the costs incident to the

              All financial statements and schedules included in material
    incorporated by reference into the Registration Statement and the

    results of operations of the Company, the Subsidiaries and the Joint
    Ventures, taken as a whole, which, in the judgment of a majority in
    interest of the Underwriters including the Representatives, is material and
    adverse and makes it impractical or inadvisable to proceed with comple tion
    of the public offering or the sale of and payment for the Securities; (ii)
    any down grading in the rating of any debt securities or preferred stock of
    the Company by any "nationally recognized statistical rating organization"

    exchange, or any suspension of trading of any securities of the Company on
    any exchange or in the over-the-counter market; (iv) any banking moratorium
    declared by Federal or New York authorities; or (v) any outbreak or

    effect of any such outbreak, escalation, declaration, calamity or

                                       16

    emergency on the financial markets makes it impracticable or inadvisable to

              (ii) Each of the Company, the Subsidiaries and the Joint Ventures
         is duly registered or qualified to do business and (to the extent

         partnership or a foreign limited liability company, as the case may
         be, in each jurisdiction, domestic or foreign, in which such
         registration, qualification or good standing is required (whether by
         reason of the ownership or leasing of property, the conduct of its
         business or otherwise), except where the failure to so register or
         qualify or be in good standing is not reasonably likely to have a
         material adverse effect on the financial condition, business or
         results of operation of the Company, the Subsid iaries and the Joint
         Ventures taken as a whole;

              (iii) The Company has the authorized and outstanding
         capitalization as set forth under the caption "Capitalization" in the

         outstanding shares of capital stock of each Subsid iary have been duly
         and validly authorized and issued and are fully paid and
         nonassessable; and to the best knowledge of such counsel, except as
         otherwise set forth in Schedule B attached hereto or disclosed in or
         contemplated by the Prospectus, all outstanding shares of capital
         stock of each Subsidiary are owned beneficially by the Company free
         and clear of any material claims, liens, encumbrances and security
         interests; and to the best knowledge of such counsel, all of the
         partnership interests in the Joint Ventures owned by the Company (as
         reflected in Schedule C attached hereto) have been duly and validly
         authorized and issued, and, except as otherwise disclosed in or

         free and clear of any material claims, liens, encumbrances and
         security interests;

              (iv) Each of the Base Indenture and the Second Supplemental
         Indenture and the MidAmerican Merger Agreement has been duly and
         validly authorized, executed and delivered by the Company and
         constitutes the legal, valid and 

                                       17

<PAGE>

         binding obligation of the Company, enforceable against the Company in
         accordance with its terms, except as enforcement may be limited by
         bankruptcy, insolvency (involving, without limitation, all laws
         relating to fraudulent trans fers), reorganization or other laws
         relating to or affecting creditors' rights generally and except as
         enforcement thereof is subject to general principles of equity

         equity or at law);

              (v) The Securities have been validly authorized by the Company,
         and, assuming due authentication by the Trustee, when issued and
         delivered as contemplated by the Indenture upon payment therefor as
         provided in this Agreement, will be validly issued and outstanding,
         and will constitute valid and binding obligations of the Company,
         entitled to the benefits of the Indenture and enforceable against the
         Company in accordance with their terms, except as enforcement may be
         limited by bankruptcy, insolvency (involving, without limitation, all

         equity or at law);

              (vi) The statements in the Prospectus under the captions
         "Description of the Securities" and "Description of Debt Securities,"
         insofar as they purport to summarize the provisions of the Indenture
         and the Securities, fairly summarized such provisions in all material
         respects.

              (vii) To such counsel's knowledge, except as otherwise disclosed
         in the Prospectus, there are no contracts, agreements or

         brokerage commission, finder's fee or other like payment;

              (viii) To such counsel's knowledge, there are no contracts,

         such person or to require the Company to include any such securities

         or in any securities being registered pursuant to any other regis
         tration statement filed by the Company under the Act;

              (ix) Except as disclosed in or contemplated by the Prospectus,
         each of the Company, the Subsidiaries and the Joint Ventures has good
         and valid title to, or valid and enforceable leasehold or contractual
         interests in, all real prop erties and all other properties and assets
         owned or leased by each of them that are material to

                                       18

         Registration Statement or (ii) that, if determined adversely to the
         Company, any Subsidiary or any Joint Venture, is reasonably likely to
         have, individually or in the aggregate, a material adverse effect on
         the financial condition, business or results of operations of the
         Company, the Subsidiaries and the Joint Ventures taken as a whole or
         on the ability of the Company to perform its obligations under this
         Agreement, the Indenture or the Securities;

              (xi) To such counsel's knowledge, the Company, each Subsidiary
         and each Joint Venture (i) has obtained each license, permit,

         their businesses as described in the Prospectuses and (ii) is in
         compliance with all terms and conditions of such license, permit,
         certificate, franchise or other governmental authorization, except (x)

    that (i) such counsel (in the case of Willkie Farr & Gallagher, such
    counsel may state that they have acted as special counsel to the Company
    for purposes of the offering of the Securities) have participated in
    conferences with representatives of the Company, some of which have been
    attended by the Underwriters and their counsel, at which conferences the
    contents of the Registration Statement, the Prospectus, each amendment
    thereof and supplement thereto and related matters were discussed, although
    such counsel has not independently checked or verified and is not passing
    upon and assumes no responsibility for the factual accuracy, completeness
    or fairness of the statements (except to the extent set forth in the
    opinion of such counsel) contained in the Registra tion Statement, the
    Prospectus, any amendment thereof or supplement thereto, and did not
    participate in the preparation of the documents incorporated by reference
    in the Registration Statement and (ii) based on the foregoing, no facts
    have come to the atten tion of such counsel which cause them to believe

    financial and statistical information contained therein or omitted
    therefrom as to all of which such counsel need not express any belief) (I)
    the Registration Statement, as of its effective date and as of the date of
    this Agreement, contained any untrue statement of a material fact or
    omitted to state a material fact required to be stated therein or necessary
    in order to make the statements therein not misleading, or that the
    Prospectus, as amended and supplemented as of the date of this Agreement or
    the Delivery Date, contain any untrue statement of a material fact or omit
    to state a material fact required to be stated therein or necessary in
    order to make the statements therein, in light of the circumstances under
    which they were made, not misleading or (II), in the case of the General
    Counsel of the Company, any document incorporated by reference in the
    Prospectus or any further amendment or supplement to such incorporated
    document made by the Company prior to the Delivery Date when they became
    effective or were filed with the Commission, as the case may be, contained,
    in the case of a registration statement that became effective under the
    Act, any untrue statement of a material fact or omitted to state a material
    fact required to be stated therein, in the light of the circumstances under
    which they were made, or necessary in order to make the statements therein
    not misleading, or, in the case of other documents which were filed under
    the Exchange Act with the Commission, an untrue statement of a material
    fact or omitted to state a material fact necessary in order to make the
    statements therein, in light of the circumstances under which they were
    made, not misleading.

              (h) The Representatives shall have received from Skadden, Arps,
    Slate Meagher & Flom LLP, counsel for the Underwriters, such opinion or
    opinions, dated the Delivery Date, with respect to the issuance and sale of
    the Securities, the Regis tration Statement, the Prospectus and other
    related matters as the Representatives may require, and the Company shall
    have furnished to such counsel such documents as they request for the
    purpose of enabling them to pass upon such matters.

                                       23

              (i) The Representatives shall have received a certificate, dated
    the Delivery Date, of the President or any Vice-President and a principal
    financial or accounting officer of the Company in which such officers shall
    state that, to the best of their knowledge after reasonable investigation,
    the representations and warranties of the Company in this Agreement are
    true and correct in all material respects, that the Company has complied
    with all agreements and satisfied all conditions on its part to be
    performed or satisfied hereunder at or prior to the Delivery Date, that no
    stop order suspending the effectiveness of the Registration Statement has
    been issued and no proceedings for that purpose have been instituted or are
    contemplated by the Commission and that, subsequent to the date of the most
    recent financial statements included or incorporated by reference in the
    Prospectus, there has been no material adverse change, nor any development
    or event involving a prospective material adverse change, in the financial
    condition, business or results of operations of the Company, the
    Subsidiaries and the Joint Ventures taken as a whole except as set forth in
    or contemplated by the Prospectuses or as described in such certificate.

              (j) The Representatives shall have received letters, dated the
    Delivery Date, of Deloitte & Touche LLP and such other independent
    accountants for subsidiaries and acquired businesses which meet the
    requirements of subsection (a) of this Section, except that the specified
    date referred to in such subsection will be a date not more than three days
    prior to the Delivery Date for the purposes of this subsection.

              (k) The Representatives shall have received letters, dated the
    Delivery Date, of PricewaterhouseCoopers LLP and such other independent
    accountants for subsidiaries and acquired businesses which meet the
    requirements of subsection (b) of this Section, except that the specified
    date referred to in such subsection will be a date not more than three days
    prior to the Delivery Date for the purposes of this subsection.

              (l) Since the date of the latest audited financial statements
    included or incorporated by reference in the Prospectus (i) except as
    disclosed in the Prospectus, there shall have been no material adverse
    change, or a development which is reasonably likely to lead to a material
    adverse change, in the financial condition, business or results of
    operations of the Company, the Subsidiaries and the Joint Ventures taken as
    a whole and (ii) except as disclosed in the Prospectus, there shall not
    have been any transactions entered into by the Company, the Subsidiaries or
    any Joint Venture, other than those in the ordinary course of business,
    which are material and adverse to the Company, the Subsidiaries and the
    Joint Ventures taken as a whole, and which, in the judgment of the
    Representatives, make it impracticable or inadvisable to proceed with the
    public offering or the delivery of the Securities on the terms and in the
    manner contemplated in the Prospectus.

              All opinions, letters, evidence and certificates mentioned above
    or elsewhere in this Agreement shall be deemed in compliance with the
    provisions hereof 

                                       24

<PAGE>

    only if they are in the form and substance reasonably satisfactorily to
    counsel for the Underwriters.

         8. Indemnification and Contribution.

              (a) The Company shall indemnify and hold harmless each
    Underwriter, its officers and employees and each person, if any, who
    controls any Underwriter within the meaning of the Act, from and against
    any loss, claim, damage or liability, joint or several, or any action in
    respect thereof (including, but not limited to, any loss, claim, damage,
    liability or action relating to purchases and sales of the Securities), to
    which that Underwriter, officer, employee or controlling person may become
    subject, under the Act or otherwise, insofar as such loss, claim, damage,
    liability or action arises out of, or is based upon, (i) any untrue
    statement or alleged untrue statement of a material fact contained in the
    Registration Statement, the Prospectus, or in any amendment or supplement
    thereto, or in any related preliminary prospectus or preliminary prospectus
    supplement, (ii) the omission or alleged omission to state in the
    Registration Statement or the Prospectus, or in any amendment or supplement
    thereto, or any related preliminary prospectus or preliminary prospectus
    supplement, any material fact required to be stated therein or necessary to
    make the statements therein (with respect to any prospectus or prospectus
    supplement, in light of the circumstances under which they were made) not
    misleading, and shall reimburse each Underwriter and each officer, employee
    or controlling person promptly upon demand for any legal or other expenses
    reasonably incurred by that Underwriter in connection with investigating or
    defending or preparing to defend against any such loss, claim, damage,
    liability or action 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, liability or action arises out of, or is based
    upon, an untrue statement or alleged untrue statement or omission or
    alleged omission made in any preliminary prospectus or preliminary
    prospectus supplement, the Registration Statement or the Prospectus, or in
    any such amendment or supplement, in reliance upon and in conformity with
    written information furnished to the Company through the Representatives by
    or on behalf of any Underwriter specifically for inclusion therein;
    provided, that, with respect to any untrue statement or omission in the
    Preliminary Prospectus Supplement dated September 9, 1998 (the "Preliminary
    Prospectus"), this indemnity agreement shall not inure to the benefit of
    any Underwriter, or its officers, employees or controlling persons, on
    account of any loss, claim, damage, liability or action arising from the
    sale of any Securities to any person by that Underwriter if that
    Underwriter failed to send or give a copy of the Prospectus, as the same
    may be amended or supplemented, to that person within the time required by
    the Act, and the untrue statement or alleged untrue statement of a material
    fact or omission or alleged omission to state a material fact in such
    Preliminary Prospectus was corrected in the Prospectus and the Prospectus
    was made available to the Underwriters prior to the sale of the Securities.
    For purposes of the last proviso to the immediately preceding sentence, the
    term

                                       25

<PAGE>

    "Prospectus" shall not be deemed to include the documents incorporated by
    reference therein, and no Under writer shall be obligated to send or give
    any supplement or amendment to any document incorporated by reference in
    the Preliminary Prospectus or Prospectus to any person other than a person
    to whom such Underwriter had delivered such incorporated document or
    documents in response to a written request therefor.

              (b) Each Underwriter, severally and not jointly, shall indemnify
    and hold harmless the Company, its officers and employees, each of its
    directors, and each person, if any, who controls the Company within the
    meaning of the Act, from and against any loss claim, damage or liability,
    joint or several, or any action in respect thereof, to which the Company
    may become subject, under the Act or otherwise, insofar as such loss,
    claim, damage, liability or action arises out of, or is based upon, (i) any
    untrue statement or alleged untrue statement of a material fact contained
    (A) in the Registration Statement or the Prospectus or in any amendment or
    supplement thereto, or any related preliminary prospectus or preliminary
    prospectus supplement or (ii) the omission or alleged omission to state in
    the Registration Statement or the Prospectus, or in any amendment or
    supplement thereto, or in any related preliminary prospectus or preliminary
    prospectus supplement, any material fact required to be stated therein or
    necessary to make the statements therein (with respect to any prospectus or
    prospectus supplement, in the light of the circumstances under which they
    were made) not misleading, but in each case only to the extent that the
    untrue statement or alleged untrue statement or omission or alleged
    omission was made in reliance upon and in conformity with written
    information furnished to the Company through the Representatives by or on
    behalf of such Underwriter specifically for inclusion therein, and shall
    reimburse the Company and any such director, officer or controlling person
    for any legal or other expenses reasonably incurred by the Company in
    connection with investigating or defending or preparing to defend against
    any such loss, claim, damage, liability or action as such expenses are
    incurred. The foregoing indemnity agreement is in addition to any liability
    which any Underwriter may otherwise have to the Company or any such
    director, officer, employee or controlling person.

              (c) Promptly after receipt by an indemnified party under this
    Section 8 of notice of any claim or the commencement of any action, the
    indemnified party shall, if a claim in respect thereof is to be made
    against the indemnifying party under this Section 8, notify the
    indemnifying party in writing of the claim or the commencement of that
    action; provided, however, that the failure to notify the indemnifying
    party shall not relieve it from any liability which it may have under this
    Section 8 except to the extent it has been materially prejudiced by such
    failure and, provided further, that the failure to notify the indemnifying
    party shall not relieve it from any liability which it may have to an
    indemnified party otherwise than under this Section 8. If any such claim or
    action shall be brought against an indemnified party, and it shall notify
    the indemnifying party thereof, the indemnifying party shall be entitled to
    participate therein and, to the extent that it wishes, jointly with any
    other similarly notified indemnifying party, to assume the

                                       26

<PAGE>

    defense thereof with counsel reasonably satisfactory to the indemnified
    party. After notice from the indemnifying party to the indemnified party of
    its election to assume the defense of such claim or action, the
    indemnifying party shall not be liable to the indemnified party under this
    Section 8 for any legal or other expenses subsequently incurred by the
    indemnified party in connection with the defense thereof other than
    reasonable costs of investigation; provided, however, that the
    Representatives shall have the right to employ counsel to represent jointly
    the Representatives and those other Underwriters and their respective
    officers, employees and controlling persons who may be subject to liability
    arising out of any claim in respect of which indemnity may be sought by the
    Underwriters against the Company under this Section 8 if the employment of
    such counsel shall have been authorized in writing by the Company in
    connection with the defense of such action or, if in the writ ten opinion
    of counsel to either the Company or the Representatives, representation of
    both parties by the same counsel would be inappropriate due to actual or
    likely conflicts of interest between the Representatives and those
    Underwriters, officers, employees, directors and controlling persons and in
    that event the fees and expenses of such separate counsel shall be paid by
    the Company. No indemnifying party shall (i) without the prior written
    consent of the indemnified parties (which consent shall not be unreasonably
    withheld), settle or compromise or consent to the entry of any judgment
    with respect to any pending or threatened claim, action, suit or proceeding
    in respect of which indemnification or contribution may be sought hereunder
    (whether or not the indemnified parties are actual or potential parties to
    such claim or action) unless such settlement, compromise or consent
    includes an unconditional release of each indemnified party from all
    liability arising out of such claim, action, suit or proceeding, or (ii) be
    liable for any settlement of any such action effected without its written
    consent (which consent shall not be unreasonably withheld), but if settled
    with the consent of the indemnifying party or if there be a final judgment
    of the plaintiff in any such action, the indemnifying party agrees to
    indemnify and hold harmless any indemnified party from and against any loss
    or liability by reason of such settlement or judgment.

              (d) If the indemnification provided for in this Section 8 shall
    for any reason be unavailable to or insufficient to hold harmless an
    indemnified party under Section 8(a) or 8(b) in respect of any loss, claim,
    damage or liability, or any action in respect thereof, referred to therein,
    then each indemnifying party shall, in lieu of indemnifying such
    indemnified party, contribute to the amount paid or payable by such
    indemnified party as a result of such loss, claim, damage or liability, or
    action in respect thereof, (i) in such proportion as shall be appropriate
    to reflect the relative benefits received by the Company on the one hand
    and the Underwriters on the other from the offering of the Securities or
    (ii) if the allocation provided by clause (i) above is not permitted by
    applicable law, in such proportion as is appropriate to reflect not only
    the relative benefits referred to in clause (i) above but also the relative
    fault of the Company on the one hand and the Underwriters on the other with
    respect to the statements or omissions which resulted in such loss, claim,
    damage or liability, or action in respect

                                       27

<PAGE>

    thereof, as well as any other relevant equitable considerations. The
    relative benefits received by the Company on the one hand and the
    Underwriters on the other with respect to such offering shall be deemed to
    be in the same proportion as the total net proceeds from the offering of
    the Securities purchased under this Agreement (before deducting expenses)
    received by the Company, bear to the total underwriting discounts and
    commissions received by the Underwriters with respect to the Securities
    purchased under this Agreement. The 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 Underwriters, 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
    Underwriters agree that it would not be just and equitable if contribution
    pursuant to this Section were to be 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 into account the equitable
    considerations referred to herein. The amount paid or payable by an
    indemnified party as a result of the loss, claim, damage or liability, or
    action in respect thereof, referred to above in this Section shall be
    deemed to include, for purposes of this Section 8(d), 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 8(d), no Underwriter shall be required to
    contribute any amount in excess of the amount by which the total price at
    which the amount of Securities underwritten by it and distributed to the
    public was offered to the public exceeds the amount of any damages which
    such Underwriter has otherwise paid or become liable to pay by reason of
    any 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 Underwriters'
    obligations to contribute as provided in this Section 11(d) are several in
    proportion to their respective underwriting obligations and not joint.

              (e) The Underwriters severally confirm and the Company
    acknowledges that the statements with respect to the public offering of the
    Securities by the Underwriters set forth on the cover page concerning the
    terms of the offering by the Underwriters and the information relating to
    over-allotments and stabilizing in paragraphs 7, 8, 9 and 10 in the section
    "Underwriting" in the Prospectus constitute the only information concerning
    such Underwriters furnished in writing to the Company by or on behalf of
    the Underwriters specifically for inclusion in the Registration Statement
    and the Prospectus.

                                       28

         9. Defaulting Underwriters.

         If, on the Delivery Date, any Underwriter defaults in the performance
of its obligations under this Agreement, the remaining non-defaulting
Underwriters shall be obligated to purchase the Securities which the defaulting
Underwriter agreed but failed to purchase on the Delivery Date in the
respective proportions which the principal amount of the Securities set
opposite the name of each remaining non-defaulting Underwriter in Schedule A
hereto bears to the aggregate principal amount of the Securities set opposite
the names of all the remaining non-defaulting Underwriters in Schedule A
hereto; provided, however, that the remaining non-defaulting Underwriters shall
not be obligated to purchase any of the Securities on the Delivery Date if the
aggregate principal amount of the Securities which the defaulting Underwriter
or Underwriters agreed but failed to purchase on such date exceeds 10% of the
aggregate principal amount of the Securities to be purchased on the Delivery
Date, and any remaining non-defaulting Underwriter shall not be obligated to
purchase more than 110% of the aggregate principal amount of the Securities
which it agreed to purchase on the Delivery Date pursuant to the terms of
Section 3. If the foregoing maximums are exceeded, the remaining non-defaulting
Underwriters, or those other underwriters satisfactory to the Representatives
who so agree, shall have the right, but shall not be obligated, to purchase, in
such proportion as may be agreed upon among them, the aggregate principal
amount of the Securities to be purchased on the Delivery Date. If the remaining
Underwriters or other underwriters satisfactory to the Representatives do not
elect to purchase the principal amount of Securities which the defaulting
Underwriter or Underwriters agreed but failed to purchase within 36 hours after
such default, this Agreement shall terminate without liability on the part of
any non-defaulting Underwriter or the Company, except that the Company will
continue to be liable for the payment of expenses to the extent set forth in
Sections 6 and 11. As used in this Agreement, the term "Underwriter" includes,
for all purposes of this Agreement unless the context requires otherwise, any
party not listed in Schedule A hereto who, pursuant to this Section 9,
purchases Securities which a defaulting Underwriter agreed but failed to
purchase.

         Nothing contained herein shall relieve a defaulting Underwriter of any
liability it may have to the Company for damages caused by its default. If
other underwriters are obligated or agree to purchase the Securities of a
defaulting or withdrawing Underwriter, either the Representative or the Company
may postpone the Delivery Date for up to seven full business days in order to
effect any changes that in the opinion of counsel for the Company or counsel
for the Underwriters may be necessary in the Registration Statement, the
Prospectus or in any other document or arrangement.

         10. Termination. The obligations of the Underwriters hereunder may be
terminated by the Representatives by notice given to and received by the
Company prior to delivery of and payment for the Securities if, prior to that
time, any of the events described in Sections 7(d) or 7(l), shall have occurred
or if the Underwriters shall decline to purchase the Notes for any reason
permitted under this Agreement.

                                       29

<PAGE>

         11. Reimbursement of Underwriters' Expenses. If the Company shall fail
to tender the Securities for delivery to the Underwriters by reason of any
failure, refusal or inability on the part of the Company to perform any
material agreement on its part to be performed, or because any other material
condition of the Underwriters' obligations hereunder required to be fulfilled
by the Company is not fulfilled, the Company will reimburse the Underwriters
for all reasonable out-of-pocket expenses (including fees and disbursements of
counsel) reasonably incurred by the Underwriters in connection with this
Agreement and the proposed purchase of the Securities in excess of $250,000,
and upon demand the Company shall pay the full amount thereof to the
Representatives; provided, however, that in no event shall such amount exceed
$100,000. If this Agreement is terminated pursuant to Section 9 by reason of
the default of one or more Underwriters, the Company shall not be obligated to
reimburse any defaulting Underwriter on account of those expenses.

         12. Notices, etc. All statements, requests, notices and agreements
hereunder shall be in writing, and:

              (a) if to the Underwriters, shall be delivered or sent by mail,
    telex or facsimile transmission to Credit Suisse First Boston Corporation,
    Eleven Madison Avenue, New York, New York 10010, Attention: Investment
    Banking Department/Transaction Advisory Group (Fax: (212) 325-8278);

              (b) 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: General Counsel (Fax: (402) 231-1658);

              provided, however, that any notice to an Underwriter pursuant to
    Section 8(c) shall be delivered or sent by mail, telex or facsimile
    transmission to such Underwriter at its address set forth in its acceptance
    telex to the Representatives, which address will be supplied to any other
    party hereto by the Representatives upon request. Any such statements,
    requests, notices or agreements shall take effect at the time of receipt
    thereof. The Company shall be entitled to act and rely upon any request,
    consent, notice or agreement given or made on behalf of the Underwriters by
    CSFB on behalf of the Representatives.

         13. Persons Entitled to Benefit of Agreement. This Agreement shall
inure to the benefit of and be binding upon the Underwriters, the Company and
their respective successors. This Agreement and the terms and provisions hereof
are for the sole benefit of only those persons, except that (A) the
representations, warranties, indemnities and agreements of the Company
contained in this Agreement shall also be deemed to be for the benefit of the
person or persons, if any, who control any Underwriter within the meaning of
Section 15 of the Act and (B) the indemnity agreement of the Underwriters
contained in Section 8(b) of this Agreement shall be deemed to be for the
benefit of directors of the Company, officers of the Company who have signed
the Registration Statement and any person controlling the Company within the
meaning of

                                       30

<PAGE>

Section 15 of the Act. Nothing in this Agreement is intended or shall be
construed to give any person, other than the persons referred to in this
Section 13, any legal or equitable right, remedy or claim under or in respect
of this Agreement or any provision contained herein.

         14. Survival. The respective indemnities, representations, warranties
and agreements of the Company and the Underwriters contained in this Agreement
or made by or on behalf on them, respectively, pursuant to this Agreement,
shall survive the delivery of and payment for the Securities and shall remain
in full force and effect, regardless of any investigation made by or on behalf
of any of them or any person controlling any of them.

         15. Definition of the Term "Business Day". For purposes of this
Agreement, "business day" means any day on which the New York Stock Exchange,
Inc. is open for trading.

         16. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF NEW YORK.

         Each party irrevocably agrees that any legal suit, action or
proceeding arising out of or based upon this Agreement or the transactions
contemplated hereby ("Related Proceedings") may be instituted in the federal
courts of the United States of America located in the City of New York or the

counterparts and, if executed in more than one counterpart, the executed
counterparts shall each be deemed to be an original but all such counterparts

                  SECTION 2.6.  Restrictions on Liens

                  Following the Rating Event Date:

                  (a) So long as any of the Securities are outstanding, the
Company shall not pledge, mortgage, hypothecate or permit to exist any
mortgage, pledge or other lien upon any property or assets at any time directly
owned by the Company to secure any Indebtedness, without making effective
provisions whereby the Securities shall be equally and ratably secured with any
and all such Indebtedness and with any other Indebtedness similarly entitled to
be equally and ratably secured; provided however, that this Section 2.6(a)
shall not apply to or prevent the creation or exis tence of: (i) liens existing
on the Rating Event Date; (ii) purchase money liens which do not exceed the
cost or value of the purchased property or assets; (iii) liens not to exceed

<PAGE>



granted in connection with extending, renewing, replacing or refinancing in
whole or in part the Indebtedness (including, without limitation, increasing
the principal amount of such Indebtedness) secured by liens described in the
foregoing clauses (i) through (iii), provided that the liens in connection with
any such extension, renewal, replacement or refinancing will be limited to the
specific property or assets that was subject to the original lien.

                  (b) In the event that the Company shall propose to pledge,
mort gage or hypothecate or permit to exist any pledge, mortgage or other lien
upon any property or assets at any time directly owned by it to secure any
Indebtedness, other than as permitted by clauses (i) through (iv) of subsection
(a) above, the Company shall give prior written notice thereof to the Trustee
and the Company will, prior to or simultaneously with such pledge, mortgage or
hypothecation, effectively secure all the Securities equally and ratably with
such Indebtedness.

                  (c) The provisions of this Section 2.6 shall not restrict the
ability of the Company's Subsidiaries and Affiliates to pledge, mortgage,
hypothecate or permit to exist any mortgage, pledge or lien upon their property
or assets, in connec tion with project financings or otherwise.

                  SECTION 2.7.  Consolidation, Merger, Sale of Assets

                  Following the Rating Event Date:

                  (a) So long as any of the Securities are outstanding, the
Company shall not consolidate with or merge with or into any other Person, or
convey, transfer or lease its consolidated properties and assets substantially
as an entirety to any Person, or permit any Person to merge into or consolidate
with the Company, unless: (i) the Company is the surviving or continuing
corporation or the surviving or con tinuing corporation or purchaser or lessee
is a corporation incorporated under the laws of the United States of America,
one of the States thereof or the District of Columbia or Canada and assumes the
Company's obligations under the Securities and under the Indenture and (ii)
immediately before and after such transaction, no Event of Default shall have
occurred and be continuing.

                  (b) Except for a sale of the consolidated properties and
assets of the Company substantially as an entirety pursuant to subsection (a)
above, and other than properties or assets required to be sold to conform with
laws or governmental regulations, the Company shall not, directly or
indirectly, sell or otherwise dispose of any of its consolidated properties or
assets (other than short-term, readily marketable investments purchased for
cash management purposes with funds not representing the proceeds of other
asset sales) if on a pro forma basis, the aggregate net book value of all such
sales during the most recent 12-month period would exceed 10% of Consolidated
Net Tangible Assets computed as of the end of the most recent quarter




<PAGE>



preceding such sale; provided, however, that any such sales shall be
disregarded for purposes of this 10% limitation if the net proceeds are
invested in properties or assets in similar or related lines of business of the
Company and its Subsidiaries and, provided further, that the Company may sell
or otherwise dispose of consolidated properties and assets in excess of such
10% limitation if the net proceeds from such sales or dispositions, which are
not reinvested as provided above, are retained by the Company as cash or Cash
Equivalents or used to retire Indebtedness of the Company (other than
Indebtedness which is subordinated to the Securities) and its Subsidiaries.

                  SECTION  2.8.  Redemption.

                  The Securities are not subject to any mandatory sinking fund.

                  The Securities are subject to optional redemption by the
Company in whole at any time, or in part from time to time, upon notice as
provided in the Section 1105 of the Indenture, at a redemption price equal to
100% of the principal amount of the Securities to be redeemed, plus interest
accrued on such principal amount through the Redemption Date plus a yield
maintenance premium (the "Premium") calculated by the Company with respect to a
particular series of Securi ties as of the Redemption Date as follows:

                  (1) the average life of the remaining scheduled payments of
         principal in respect of outstanding Securities of such series (the
         "Remaining Average Life") shall be calculated as of the Redemption
         Date;

                  (2) the yield to maturity shall be calculated as of the
         Business Day immediately preceding the Redemption Date for the United
         States Treasury security having an average life equal to the Remaining
         Average Life and trading in the secondary market at the price closest
         to par (the "Primary Issue"); provided, however, that if no United
         States Treasury security has an average life equal to the Remaining
         Average Life, the yields (the "Other Yields") for the two maturities
         of United States Treasury securities having average lives most closely
         corresponding to such Remaining Average Life and trading in the
         secondary market at the price closest to par shall be calcu lated, and
         the yield to maturity for the Primary Issue shall be the yield
         interpolated or extrapolated from such Other Yields on a straight-line
         basis, rounding in each of such relevant periods to the nearest month;

                  (3) the discounted present value of the then remaining
         scheduled payments of principal and interest (but excluding that
         portion of any sched uled payment of interest that is actually due and
         paid on the Redemption Date) in respect of outstanding Securities of
         such series shall be calculated as of the Redemption Date using a
         discount factor equal to the sum of (a) the yield to maturity for the
         Primary Issue, plus (b) (i) 25 basis points for the




<PAGE>



         2003 Notes, (ii) 37.5 basis points for the 2005 Notes, (iii) 37.5
         basis points for the 2008 Notes or (iv) 50 basis points for the Bonds;
         and

                  (4) the amount of Premium in respect of Securities to be
         redeemed shall be an amount equal to (a) the discounted present value
         of such Securities to be redeemed determined in accordance with clause
         (3) above minus (b) the unpaid principal amount of such Securities;
         provided, however, that the Premium shall not be less than zero.

                  The Trustee may conclusively rely on an Officers' Certificate
setting forth the calculation of the Premium, which Officers' Certificate shall
be delivered to the Trustee on or before the Redemption Date.

                  SECTION 2.9.  Global Form.

                  The Securities shall initially be issued in the form of one
or more Global Securities as provided in Section 201(a) of the Indenture. The
Depositary for the Securities shall be The Depository Trust Company. Except as
otherwise pro vided in Sections 201, 307 or 309 of the Indenture, owners of
beneficial interests in the Global Security or Securities will not be entitled
to receive physical delivery of Certificated Securities.

Exhibit B hereto. The 2008 Notes shall be substantially in the form attached as
Exhibit C hereto. The Bonds shall be substantially in the form attached as

on) the Securities shall be made only upon presen tation and surrender thereof
at any such office or agency and, at the option of the Company, payment of
interest may be made by check mailed to the address of the Person entitled
thereto as such address shall appear in the Security Register.

to those covenants specified in Section 1203 of the Indenture.

                             (REVERSE OF SECURITY)


                  This Security is one of a duly authorized issue of Debt
Securities of the Company designated as its 6.96% Senior Notes due 2003 (herein
called the "Securities"), limited in aggregate principal amount of $215,000,000
issued and to be issued under an Indenture, dated as of October 15, 1997, as
supplemented by the First Supplemental Indenture dated as of October 28, 1997
and by the Second Supplemental Indenture dated as of September 22, 1998 (as so
supplemented, herein called the "Indenture", which term shall have the meaning
assigned to it in such in strument), between the Company and IBJ Schroder Bank
& Trust Company, as Trustee (herein called the "Trustee" which term includes
any successor trustee under the Indenture), and reference is hereby made to the
Indenture 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 of the terms upon which the Securities are, and are to be,
authenticated and delivered.

                  The Securities do not have the benefit of any sinking fund
obligations.

                  The Securities are subject to optional redemption by the
Company in whole at any time, or in part from time to time, at a redemption
price equal to 100% of the principal amount of the Securities to be redeemed,
plus interest accrued on such principal amount through the Redemption Date plus
a Premium calculated as of the Redemption Date, as provided in the Second
Supplemental Indenture dated as of September 22, 1998.

                  Upon the occurrence of a Change of Control, the Company shall
be required to make an Offer to Purchase all or a specified portion of the
Securities at a purchase price in cash equal to 101% of the principal amount
thereof on any Pur chase Date plus accrued and unpaid interest, if any, to such
Purchase Date. If the Company, any Restricted Subsidiary or any Eligible Joint
Venture consummates an Asset Disposition, under certain circumstances, the
Company shall be required to make an Offer to Purchase up to all or a specified
portion of the Securities at a purchase price in cash equal to 100% of the
principal amount thereof on any Pur chase Date, plus accrued and unpaid
interest, if any, to such Purchase Date, in an amount equal to any Net Cash
Proceeds from such an Asset Disposition that are not used to reinvest in the
business of the Company and/or repay in a permanent reduc tion of Debt of the
Company or Debt of its Restricted Subsidiaries or Eligible Joint Ventures.
Holders of Securities shall receive notice of any such Offer to Purchase from
the Company prior to the related Purchase Date and may elect to have such
Securities purchased by completing the form entitled "Option of Holder to Elect
Purchase" appearing on the reverse side of this Security.



                                      A-5

<PAGE>



                  In the event of purchase, pursuant to an Offer to Purchase,
of this Security in part only, a new Security or Securities for the portion
hereof not pur chased shall be issued in the name of the Holder hereof upon
surrender of this Security to the Trustee for cancellation thereof.

                  Following the Rating Event Date (and provided no Event of
Default or Default shall exist on the Rating Event Date), substantially all the
covenants contained in the Indenture (excluding the covenant relating to the
Company's obligation to make an Offer to Purchase Securities upon the
occurrence of a Change of Control) will cease to apply to the Securities. In
their place, certain other cove nants regarding restrictions on liens and the
ability of the Company to merge or consolidate with or into any other Person,

supplemented by the First Supplemental Indenture dated as of October 28, 1997
and by the Second Supplemental Indenture dated as of September 22, 1998 (as so
supplemented, herein called the "Indenture", which term shall have the meaning
assigned to it in such in strument), between the Company and IBJ Schroder Bank
& Trust Company, as Trustee (herein called the "Trustee" which term includes
any successor trustee under the Indenture), and reference is hereby made to the
Indenture 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 of the terms upon which the Securities are, and are to be,

                  The Securities do not have the benefit of any sinking fund
obligations.

                  The Securities are subject to optional redemption by the

                  In the event of purchase, pursuant to an Offer to Purchase,

hereof not pur chased shall be issued in the name of the Holder hereof upon
surrender of this Security to the Trustee for cancellation thereof.

                  Following the Rating Event Date (and provided no Event of
Default or Default shall exist on the Rating Event Date), substantially all the
covenants contained in the Indenture (excluding the covenant relating to the
Company's obligation to make an Offer to Purchase Securities upon the
occurrence of a Change of Control) will cease to apply to the Securities. In
their place, certain other cove nants regarding restrictions on liens and the
ability of the Company to merge or consolidate with or into any other Person,
or to transfer or lease assets will apply to the Securities.

of the entire Debt of the Company with respect to this Security or certain
restrictive covenants and Events of Default with respect to this Security,

such date.

                  The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Holders of the Securities
under the Indenture at any time by the Company and the Trustee with the consent
of the Holders of a majority in aggregate principal amount of the Securities at
the time Outstanding. The Inden ture also contains provisions permitting the
Holders of specified percentages in aggregate principal amount of the
Securities of any series at the time Outstanding, on behalf of the Holders of
all Securities of such series, to waive compliance by the Company with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences in each case with respect to the Securities of such series.
In addition, without the consent of any Holder of a Security, the Indenture and
the Securities may be amended and supplemented to cure any ambiguity or
inconsistency, make other changes that shall not adversely affect the rights of
the Holders or certain other matters specified in the Indenture. Any such
consent or waiver by the Holder of this Security shall be conclusive and
binding upon such Holder and upon all future Holders of this Security and of
any Security issued upon the registration of transfer hereof or in exchange
herefor or in lieu hereof, whether or not notation of such consent or waiver is

                             (REVERSE OF SECURITY)


                  This Security is one of a duly authorized issue of Debt
Securities of the Company designated as its 7.52% Senior Notes due 2008 (herein
called the "Securities"), limited in aggregate principal amount of $450,000,000
issued and to be issued under an Indenture, dated as of October 15, 1997, as
supplemented by the First Supplemental Indenture dated as of October 28, 1997
and by the Second Supplemental Indenture dated as of September 22, 1998 (as so
supplemented, herein called the "Indenture", which term shall have the meaning
assigned to it in such in strument), between the Company and IBJ Schroder Bank
& Trust Company, as Trustee (herein called the "Trustee" which term includes
any successor trustee under the Indenture), and reference is hereby made to the
Indenture 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 of the terms upon which the Securities are, and are to be,
authenticated and delivered.

                  The Securities do not have the benefit of any sinking fund
obligations.

                  The Securities are subject to optional redemption by the
Company in whole at any time, or in part from time to time, at a redemption
price equal to 100% of the principal amount of the Securities to be redeemed,
plus interest accrued on such principal amount through the Redemption Date plus
a Premium calculated as of the Redemption Date, as provided in the Second
Supplemental Indenture dated as of September 22, 1998.

                  Upon the occurrence of a Change of Control, the Company shall
be required to make an Offer to Purchase all or a specified portion of the
Securities at a purchase price in cash equal to 101% of the principal amount
thereof on any Pur chase Date plus accrued and unpaid interest, if any, to such
Purchase Date. If the Company, any Restricted Subsidiary or any Eligible Joint
Venture consummates an Asset Disposition, under certain circumstances, the
Company shall be required to make an Offer to Purchase up to all or a specified
portion of the Securities at a purchase price in cash equal to 100% of the
principal amount thereof on any Pur chase Date, plus accrued and unpaid
interest, if any, to such Purchase Date, in an amount equal to any Net Cash
Proceeds from such an Asset Disposition that are not used to reinvest in the
business of the Company and/or repay in a permanent reduc tion of Debt of the
Company or Debt of its Restricted Subsidiaries or Eligible Joint Ventures.
Holders of Securities shall receive notice of any such Offer to Purchase from
the Company prior to the related Purchase Date and may elect to have such
Securities purchased by completing the form entitled "Option of Holder to Elect
Purchase" appearing on the reverse side of this Security.



                                      C-5

<PAGE>



                  In the event of purchase, pursuant to an Offer to Purchase,
of this Security in part only, a new Security or Securities for the portion
hereof not pur chased shall be issued in the name of the Holder hereof upon
surrender of this Security to the Trustee for cancellation thereof.

                  Following the Rating Event Date (and provided no Event of
Default or Default shall exist on the Rating Event Date), substantially all the
covenants contained in the Indenture (excluding the covenant relating to the
Company's obligation to make an Offer to Purchase Securities upon the
occurrence of a Change of Control) will cease to apply to the Securities. In
their place, certain other cove nants regarding restrictions on liens and the
ability of the Company to merge or consolidate with or into any other Person,
or to transfer or lease assets will apply to the Securities.

                  The Indenture contains provisions for defeasance at any time
of the entire Debt of the Company with respect to this Security or certain
restrictive covenants and Events of Default with respect to this Security,
including, without limitation, covenants relating to Offers to Purchase, in
each case upon compliance with certain conditions set forth in the Indenture.

                  If an Event of Default shall occur and be continuing, there
may be declared due and payable the Default Amount of the Securities, in the
manner and with the effect provided in the Indenture. The Default Amount in
respect of this Security as of any particular date shall equal 100% of the
principal amount of this Security plus accrued and unpaid interest, if any, to
such date.

                  The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Holders of the Securities
under the Indenture at any time by the Company and the Trustee with the consent
of the Holders of a majority in aggregate principal amount of the Securities at
the time Outstanding. The Inden ture also contains provisions permitting the
Holders of specified percentages in aggregate principal amount of the
Securities of any series at the time Outstanding, on behalf of the Holders of
all Securities of such series, to waive compliance by the Company with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences in each case with respect to the Securities of such series.
In addition, without the consent of any Holder of a Security, the Indenture and
the Securities may be amended and supplemented to cure any ambiguity or
inconsistency, make other changes that shall not adversely affect the rights of
the Holders or certain other matters specified in the Indenture. Any such
consent or waiver by the Holder of this Security shall be conclusive and
binding upon such Holder and upon all future Holders of this Security and of
any Security issued upon the registration of transfer hereof or in exchange
herefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Security.

                  As provided in and subject to the provisions of the
Indenture, the Holder of this Security shall not have the right to institute
any proceeding with respect to the Indenture or for the appointment of a
receiver, or trustee or for any other remedy thereunder, unless such Holder
shall have previously given the Trustee written notice of a continuing Event of
Default with respect to the Securities, the Holders of not less than 25% in
principal amount of the Securities of this series at the time Outstanding shall
have made written request to the Trustee to institute proceed ings in respect
of such Event of Default as Trustee and offered the Trustee reasonable
indemnity, and the Trustee shall not have received from the Holders of a
majority in principal amount of Securities of this series at the time
Outstanding a direction inconsistent with such request and shall have failed to
institute any such proceeding for 60 days after receipt of such notice, request
and offer of indemnity. The forego ing shall not apply to certain suits
described in the Indenture, including any suit instituted by the Holder of this
Security for the enforcement of any payment of principal hereof or any premium
or interest hereon on or after the respective due dates expressed herein (or,
in the case of any purchase of this Security required to be made pursuant to an
Offer to Purchase, on or after the Purchase Date).

                  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 (and
premium, if any) and interest on this Security at the times, place, manner and
rate, and in the coin or currency, herein prescribed.

                  As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of this Security is registrable in
the Security Register, upon surrender of this Security for registration of
transfer at the office or agency of the Company in the Borough of Manhattan,
The City of New York (which initially shall be the Corporate Trust Office of
the Trustee), duly endorsed by, or accompanied by a written instrument of
transfer in form satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Securities, of authorized denominations and for the
same aggregate principal amount, shall be issued to the designated transferee
or transferees.

                  The Securities 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 therein set forth,
Securities are exchange able for a like aggregate principal amount of
Securities of like tenor of a different authorized denomination, as requested
by the Holder surrendering the same.

                  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.

                  A director, officer, employee, stockholder or incorporator of
the Company shall not have any liability for any obligations of the Company
under this Security or the Indenture or for any claim based on, in respect of
or by reason of such obligations or their creation. Each Holder by accepting
this Security waives and releases all such liability. Such waiver and release
are part of the consideration for the issuance of this Security.

                  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 is overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

                  Interest on this Security shall be computed on the basis of a
360-day year of twelve 30-day months.

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

                  THE INDENTURE AND THIS SECURITY SHALL BE GOV ERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, INCLUDING
SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW.

America as at the time of payment is legal tender for payment of public and
private debts, provided that payment of the principal of (and premium, if any,
on) this Security shall be made only upon presentation and surrender hereof at
any such office or agency and, at the option of the Company, payment of
interest may be made by check mailed to the address of the Person entitled

                             (REVERSE OF SECURITY)


                  This Security is one of a duly authorized issue of Debt
Securities of the Company designated as its 8.48% Senior Bonds due 2028 (herein
called the "Securities"), limited in aggregate principal amount of $475,000,000
issued and to be issued under an Indenture, dated as of October 15, 1997, as
supplemented by the First Supplemental Indenture dated as of October 28, 1997
and by the Second Supplemental Indenture dated as of September 22, 1998 (as so
supplemented, herein called the "Indenture", which term shall have the meaning
assigned to it in such in strument), between the Company and IBJ Schroder Bank
& Trust Company, as Trustee (herein called the "Trustee" which term includes
any successor trustee under the Indenture), and reference is hereby made to the
Indenture 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 of the terms upon which the Securities are, and are to be,
authenticated and delivered.

                  The Securities do not have the benefit of any sinking fund
obligations.

                  The Securities are subject to optional redemption by the
Company in whole at any time, or in part from time to time, at a redemption
price equal to 100% of the principal amount of the Securities to be redeemed,
plus interest accrued on such principal amount through the Redemption Date plus
a Premium calculated as of the Redemption Date, as provided in the Second
Supplemental Indenture dated as of September 22, 1998.

                  Upon the occurrence of a Change of Control, the Company shall
be required to make an Offer to Purchase all or a specified portion of the
Securities at a purchase price in cash equal to 101% of the principal amount
thereof on any Pur chase Date plus accrued and unpaid interest, if any, to such
Purchase Date. If the Company, any Restricted Subsidiary or any Eligible Joint
Venture consummates an Asset Disposition, under certain circumstances, the
Company shall be required to make an Offer to Purchase up to all or a specified
portion of the Securities at a purchase price in cash equal to 100% of the
principal amount thereof on any Pur chase Date, plus accrued and unpaid
interest, if any, to such Purchase Date, in an amount equal to any Net Cash
Proceeds from such an Asset Disposition that are not used to reinvest in the
business of the Company and/or repay in a permanent reduc tion of Debt of the
Company or Debt of its Restricted Subsidiaries or Eligible Joint Ventures.
Holders of Securities shall receive notice of any such Offer to Purchase from
the Company prior to the related Purchase Date and may elect to have such
Securities purchased by completing the form entitled "Option of Holder to Elect
Purchase" appearing on the reverse side of this Security.



                                      D-5

<PAGE>



                  In the event of purchase, pursuant to an Offer to Purchase,
of this Security in part only, a new Security or Securities for the portion
hereof not pur chased shall be issued in the name of the Holder hereof upon
surrender of this Security to the Trustee for cancellation thereof.

                  Following the Rating Event Date (and provided no Event of
Default or Default shall exist on the Rating Event Date), substantially all the
covenants contained in the Indenture (excluding the covenant relating to the
Company's obligation to make an Offer to Purchase Securities upon the
occurrence of a Change of Control) will cease to apply to the Securities. In
their place, certain other cove nants regarding restrictions on liens and the
ability of the Company to merge or consolidate with or into any other Person,
or to transfer or lease assets will apply to the Securities.

                  The Indenture contains provisions for defeasance at any time
of the entire Debt of the Company with respect to this Security or certain
restrictive covenants and Events of Default with respect to this Security,
including, without limitation, covenants relating to Offers to Purchase, in
each case upon compliance with certain conditions set forth in the Indenture.

                  If an Event of Default shall occur and be continuing, there
may be declared due and payable the Default Amount of the Securities, in the
manner and with the effect provided in the Indenture. The Default Amount in
respect of this Security as of any particular date shall equal 100% of the
principal amount of this Security plus accrued and unpaid interest, if any, to
such date.

                  The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Holders of the Securities
under the Indenture at any time by the Company and the Trustee with the consent
of the Holders of a majority in aggregate principal amount of the Securities at
the time Outstanding. The Inden ture also contains provisions permitting the
Holders of specified percentages in aggregate principal amount of the
Securities of any series at the time Outstanding, on behalf of the Holders of
all Securities of such series, to waive compliance by the Company with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences in each case with respect to the Securities of such series.
In addition, without the consent of any Holder of a Security, the Indenture and
the Securities may be amended and supplemented to cure any ambiguity or
inconsistency, make other changes that shall not adversely affect the rights of
the Holders or certain other matters specified in the Indenture. Any such
consent or waiver by the Holder of this Security shall be conclusive and
binding upon such Holder and upon all future Holders of this Security and of
any Security issued upon the registration of transfer hereof or in exchange
herefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Security.

<PAGE>



                  As provided in and subject to the provisions of the
Indenture, the Holder of this Security shall not have the right to institute
any proceeding with respect to the Indenture or for the appointment of a
receiver, or trustee or for any other remedy thereunder, unless such Holder
shall have previously given the Trustee written notice of a continuing Event of
Default with respect to the Securities, the Holders of not less than 25% in
principal amount of the Securities of this series at the time Outstanding shall
have made written request to the Trustee to institute proceed ings in respect
of such Event of Default as Trustee and offered the Trustee reasonable
indemnity, and the Trustee shall not have received from the Holders of a
majority in principal amount of Securities of this series at the time
Outstanding a direction inconsistent with such request and shall have failed to
institute any such proceeding for 60 days after receipt of such notice, request
and offer of indemnity. The forego ing shall not apply to certain suits
described in the Indenture, including any suit instituted by the Holder of this
Security for the enforcement of any payment of principal hereof or any premium
or interest hereon on or after the respective due dates expressed herein (or,
in the case of any purchase of this Security required to be made pursuant to an
Offer to Purchase, on or after the Purchase Date).

                  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 (and
premium, if any) and interest on this Security at the times, place, manner and
rate, and in the coin or currency, herein prescribed.

                  As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of this Security is registrable in
the Security Register, upon surrender of this Security for registration of
transfer at the office or agency of the Company in the Borough of Manhattan,
The City of New York (which initially shall be the Corporate Trust Office of
the Trustee), duly endorsed by, or accompanied by a written instrument of
transfer in form satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Securities, of authorized denominations and for the
same aggregate principal amount, shall be issued to the designated transferee
or transferees.

                  The Securities 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 therein set forth,
Securities are exchange able for a like aggregate principal amount of
Securities of like tenor of a different authorized denomination, as requested
by the Holder surrendering the same.

                  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.

the Company shall not have any liability for any obligations of the Company
under this Security or the Indenture or for any claim based on, in respect of
or by reason of such obligations or their creation. Each Holder by accepting
this Security waives and releases all such liability. Such waiver and release
are part of the consideration for the issuance of this Security.

                  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 is overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

360-day year of twelve 30-day months.

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

CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, INCLUDING
